It's the response code a SIP User Agent Server (UAS) will send to the client after the client sends a CANCEL request for the original unanswered INVITE request (yet to receive a final response).

Here is a nice CANCEL SIP Call Flow illustration.

Normally HEAD points to a branch. When it is not pointing to a branch instead when it points to a commit hash like 69e51 it means you have a detached HEAD. You need to point it two a branch to fix the issue. You can do two things to fix it.

1. git checkout other_branch // Not possible when you need the code in that commit hash
2. create a new branch and point the commit hash to the newly created branch.

HEAD must point to a branch, not a commit hash is the golden rule.

The align-items, or respectively align-content attribute controls this behaviour.

align-items defines the items' positioning perpendicularly to flex-direction.

The default flex-direction is row, therfore vertical placement can be controlled with align-items.

There is also the align-self attribute to control the alignment on a per item basis.

#a {_x000D_
  display:flex;_x000D_
_x000D_
  align-items:flex-start;_x000D_
  align-content:flex-start;_x000D_
  }_x000D_
_x000D_
#a > div {_x000D_
  _x000D_
  background-color:red;_x000D_
  padding:5px;_x000D_
  margin:2px;_x000D_
  }_x000D_
 #a > #c {_x000D_
  align-self:stretch;_x000D_
 }

<div id="a">_x000D_
  _x000D_
  <div id="b">left</div>_x000D_
  <div id="c">middle</div>_x000D_
  <div>right<br>right<br>right<br>right<br>right<br></div>_x000D_
  _x000D_
</div>

css-tricks has an excellent article on the topic. I recommend reading it a couple of times.

Since Java 8 this kind of code compiles as expected and the type parameter gets inferred by the compiler.

public Person(String name) {
    this(name, Collections.emptyList()); // Inferred to List<String> in Java 8
}

public Person(String name, List<String> nicknames) {
    this.name = name;
    this.nicknames = nicknames;
}

The new thing in Java 8 is that the target type of an expression will be used to infer type parameters of its sub-expressions. Before Java 8 only direct assignments and arguments to methods where used for type parameter inference.

In this case the parameter type of the constructor will be the target type for Collections.emptyList(), and the return value type will get chosen to match the parameter type.

This mechanism was added in Java 8 mainly to be able to compile lambda expressions, but it improves type inferences generally.

Java is getting closer to proper Hindley–Milner type inference with every release!

If only two values are required to create the object with a valid state, you could simply remove all the other optional arguments and provide setters for them (unless you dont want them to changed at runtime). Then just instantiate the object with the two required arguments and set the others as needed through the setter.

Further reading

• Martin Fowler on Constructor vs Setter Injection and
• Dependency injection through constructors or property setters?

List<int>[]  a = new List<int>[100];

You still would have to allocate each individual list in the array before you can use it though:

for (int i = 0; i < a.Length; i++)
    a[i] = new List<int>();

This should do the trick:

df[- grep("REVERSE", df$Name),]

Or a safer version would be:

df[!grepl("REVERSE", df$Name),]

I got this after saving the JSON file using Notepad2, so I had to open it with Notepad++ and then say "Convert to UTF-8". Then it worked.

Yes it is true.

If you create two instance of your class

Test t1 = new Test();
Test t2 = new Test();

Then t1.foo and t2.foo both synchronize on the same static object and hence block each other.

I'm really late to party here, but most of the answers seem to be about the whys and whens of using assertions in general, rather than using AssertionError in particular.

assert and throw new AssertionError() are very similar and serve the same conceptual purpose, but there are differences.

1. throw new AssertionError() will throw the exception regardless of whether assertions are enabled for the jvm (i.e., through the -ea switch).
2. The compiler knows that throw new AssertionError() will exit the block, so using it will let you avoid certain compiler errors that assert will not.

For example:

    {
        boolean b = true;
        final int n;
        if ( b ) {
            n = 5;
        } else {
            throw new AssertionError();
        }
        System.out.println("n = " + n);
    }

    {
        boolean b = true;
        final int n;
        if ( b ) {
            n = 5;
        } else {
            assert false;
        }
        System.out.println("n = " + n);
    }

The first block, above, compiles just fine. The second block does not compile, because the compiler cannot guarantee that n has been initialized by the time the code tries to print it out.

$.each(data,function(index,itemData){
    $('#dropListBuilding').append($("<option></option>")
        .attr("value",key)
        .text(value)); 
});

I had the same problem for days until I noticed (how could I look at it and not read the code :-(..) that config.inc.php is calling config-db.php

** MySql Server version: 5.7.5-m15
** Apache/2.4.10 (Ubuntu)
** phpMyAdmin 4.2.9.1deb0.1

/etc/phpmyadmin/config-db.php:

$dbuser='yourDBUserName';
$dbpass='';
$basepath='';
$dbname='phpMyAdminDBName';
$dbserver='';
$dbport='';
$dbtype='mysql';

Here you need to define your username, password, dbname and others that are showing empty' use default unless you changed their configuration. That solved the issue for me.
U hope it helps you.

Java 8 support a more declarative approach to iteration, in that we specify the result we want rather than how to compute it. Benefits of the new approach are that it can be more readable, less error prone.

public static void mapRemove() {

    Map<Integer, String> map = new HashMap<Integer, String>() {
        {
            put(1, "one");
            put(2, "two");
            put(3, "three");
        }
    };

    map.forEach( (key, value) -> { 
        System.out.println( "Key: " + key + "\t" + " Value: " + value );  
    }); 

    map.keySet().removeIf(e->(e>2)); // <-- remove here

    System.out.println("After removing element");

    map.forEach( (key, value) -> { 
        System.out.println( "Key: " + key + "\t" + " Value: " + value ); 
    });
}

And result is as follows:

Key: 1   Value: one
Key: 2   Value: two
Key: 3   Value: three
After removing element
Key: 1   Value: one
Key: 2   Value: two

Enumerations are used to represent a set of integer values.

The class keyword after the enum specifies that the enumeration is strongly typed and its enumerators are scoped. This way enum classes prevents accidental misuse of constants.

For Example:

enum class Animal{Dog, Cat, Tiger};
enum class Pets{Dog, Parrot};

Here we can not mix Animal and Pets values.

Animal a = Dog;       // Error: which DOG?    
Animal a = Pets::Dog  // Pets::Dog is not an Animal

Try this:

bool matchFound = myList.Any(s => s.Contains("Mdd LH"));

The Any() will stop searching the moment it finds a match, so is quite efficient for this task.

The characters '<', and '>', are to indicate a place-holder, you should remove them to read:

php /usr/local/solusvm/scripts/pass.php --type=admin --comm=change --username=ADMINUSERNAME

Make sure you restart your computer after you install the Build Tools.

This was what was causing the error for me.

function setPixel(imageData, x, y, r, g, b, a) {
    var index = 4 * (x + y * imageData.width);
    imageData.data[index+0] = r;
    imageData.data[index+1] = g;
    imageData.data[index+2] = b;
    imageData.data[index+3] = a;
}

if you want both out and err streams redirected

dir >> a.txt 2>&1

myInt.ToString("D4");

In addition to Sophie's answer, I also have found a use in sending in child component types, doing something like this:

var ListView = React.createClass({
    render: function() {
        var items = this.props.data.map(function(item) {
            return this.props.delegate({data:item});
        }.bind(this));
        return <ul>{items}</ul>;
    }
});

var ItemDelegate = React.createClass({
    render: function() {
        return <li>{this.props.data}</li>
    }
});

var Wrapper = React.createClass({    
    render: function() {
        return <ListView delegate={ItemDelegate} data={someListOfData} />
    }
});

You can do it in 1 line, by using Linq

listBox1.Cast<ListItem>().Where(p=>p.Text.Contains("OBJECT")).ToList().ForEach(listBox1.Items.Remove);

I don't hear about "apstring".If you want to use string with c++ ,you can do like this:

#include<string>
using namespace std;
int main()
{
   string str;
   cin>>str;
   cout<<str;
   ...
   return 0;
}

I hope this can avail

if (false === file_get_contents("http://example.com/path/to/image")) {
    $image = $default_image;
}

Should work ;)

Use the modern version of the Fisher–Yates shuffle algorithm:

/**
 * Shuffles array in place.
 * @param {Array} a items An array containing the items.
 */
function shuffle(a) {
    var j, x, i;
    for (i = a.length - 1; i > 0; i--) {
        j = Math.floor(Math.random() * (i + 1));
        x = a[i];
        a[i] = a[j];
        a[j] = x;
    }
    return a;
}

ES2015 (ES6) version

/**
 * Shuffles array in place. ES6 version
 * @param {Array} a items An array containing the items.
 */
function shuffle(a) {
    for (let i = a.length - 1; i > 0; i--) {
        const j = Math.floor(Math.random() * (i + 1));
        [a[i], a[j]] = [a[j], a[i]];
    }
    return a;
}

Note however, that swapping variables with destructuring assignment causes significant performance loss, as of October 2017.

Use

var myArray = ['1','2','3','4','5','6','7','8','9'];
shuffle(myArray);

Implementing prototype

Using Object.defineProperty (method taken from this SO answer) we can also implement this function as a prototype method for arrays, without having it show up in loops such as for (i in arr). The following will allow you to call arr.shuffle() to shuffle the array arr:

Object.defineProperty(Array.prototype, 'shuffle', {
    value: function() {
        for (let i = this.length - 1; i > 0; i--) {
            const j = Math.floor(Math.random() * (i + 1));
            [this[i], this[j]] = [this[j], this[i]];
        }
        return this;
    }
});

I had a similar issue and blogged about it here. I started with the regular expression for alpha numerics, then added in the few basic punctuation characters I liked:

select dump(a,1016), a, b
from
 (select regexp_replace(COLUMN,'[[:alnum:]/''%()> -.:=;[]','') a,
         COLUMN b
  from TABLE)
where a is not null
order by a;

I used dump with the 1016 variant to give out the hex characters I wanted to replace which I could then user in a utl_raw.cast_to_varchar2.

I'll give you the query which you can run on kibana.

GET /_cat/indices?v

and the CURL version will be

CURL -XGET http://localhost:9200/_cat/indices?v

Some of the answers have already provided various approaches related to getting rid of the create extension and comment on extensions. For me, the following command line seemed to work and be the simplest approach to solve the problem:

cat /tmp/backup.sql.gz | gunzip - | \
  grep -v -E '(CREATE\ EXTENSION|COMMENT\ ON)' |  \
    psql --set ON_ERROR_STOP=on -U db_user -h localhost my_db

Some notes

• The first line is just uncompressing my backup and you may need to adjust accordingly.
• The second line is using grep to get rid of offending lines.
• the third line is my psql command; you may need to adjust as you normally would use psql for restore.

try your task using IN condition or OR condition and also this query is working on spark-1.6.x

 SELECT  patient, patient_id FROM `patient` WHERE patient IN ('User4', 'User3');

or

SELECT  patient, patient_id FROM `patient` WHERE patient = 'User1' OR patient = 'User2';

In ES5 or ES6 if you need check it several times you cand do:

const excluded = [null, undefined, ''];_x000D_
_x000D_
if (!exluded.includes(varToCheck) {_x000D_
  // it will bee not null, not undefined and not void string_x000D_
}

I had to add the .classpath too, form a java project. I made a dummy java project and looked in the workspace for this dummy java project to see what is required. I transferred the two files. profile and .claspath to my checked out, and disconnected source from my subversion server. From then on it turned to a java project from just a plain old project.

Break-down:

• 8 says that you want to show 8 digits
• 0 that you want to prefix with 0's instead of just blank spaces
• x that you want to print in lower-case hexadecimal.

Quick example (thanks to Grijesh Chauhan):

#include <stdio.h>
int main() {
    int data = 29;
    printf("%x\n", data);    // just print data
    printf("%0x\n", data);   // just print data ('0' on its own has no effect)
    printf("%8x\n", data);   // print in 8 width and pad with blank spaces
    printf("%08x\n", data);  // print in 8 width and pad with 0's

    return 0;
}

Output:

1d
1d
      1d
0000001d

StringBuilder is significantly more efficient but you will not see that performance unless you are doing a large amount of string modification.

Below is a quick chunk of code to give an example of the performance. As you can see you really only start to see a major performance increase when you get into large iterations.

As you can see the 200,000 iterations took 22 seconds while the 1 million iterations using the StringBuilder was almost instant.

string s = string.Empty;
StringBuilder sb = new StringBuilder();

Console.WriteLine("Beginning String + at " + DateTime.Now.ToString());

for (int i = 0; i <= 50000; i++)
{
    s = s + 'A';
}

Console.WriteLine("Finished String + at " + DateTime.Now.ToString());
Console.WriteLine();

Console.WriteLine("Beginning String + at " + DateTime.Now.ToString());

for (int i = 0; i <= 200000; i++)
{
    s = s + 'A';
}

Console.WriteLine("Finished String + at " + DateTime.Now.ToString());
Console.WriteLine();
Console.WriteLine("Beginning Sb append at " + DateTime.Now.ToString());

for (int i = 0; i <= 1000000; i++)
{
    sb.Append("A");
}
Console.WriteLine("Finished Sb append at " + DateTime.Now.ToString());

Console.ReadLine();

Result of the above code:

Beginning String + at 28/01/2013 16:55:40.

Finished String + at 28/01/2013 16:55:40.

Beginning String + at 28/01/2013 16:55:40.

Finished String + at 28/01/2013 16:56:02.

Beginning Sb append at 28/01/2013 16:56:02.

Finished Sb append at 28/01/2013 16:56:02.

ModHeader extension for Google Chrome, is also a good option. You can just set the Headers you want and just enter the URL in the browser, it will automatically take the headers from the extension when you hit the url. Only thing is, it will send headers for each and every URL you will hit so you have to disable or delete it after use.

Yes, you can simulate a mouse click by creating an event and dispatching it:

function click(x,y){
    var ev = document.createEvent("MouseEvent");
    var el = document.elementFromPoint(x,y);
    ev.initMouseEvent(
        "click",
        true /* bubble */, true /* cancelable */,
        window, null,
        x, y, 0, 0, /* coordinates */
        false, false, false, false, /* modifier keys */
        0 /*left*/, null
    );
    el.dispatchEvent(ev);
}

Beware of using the click method on an element -- it is widely implemented but not standard and will fail in e.g. PhantomJS. I assume jQuery's implemention of .click() does the right thing but have not confirmed.

Here is the code I use which doesn't have any issues decoding large images in memory on Android. I have been able to decode images larger then 20MB as long as my input parameters are around 1024x1024. You can save the returned bitmap to another file. Below this method is another method which I also use to scale images to a new bitmap. Feel free to use this code as you wish.

Using the stack is convenient(like recursive call), but it comes at a cost: storing detailed information can take up a lot of memory.

If the stack is high, it means that the computer stores a lot of information about function calls.

The method only takes up constant memory(like iteration).

Or Using for loop

def fact(n):
    result = 1
    for i in range(2, n + 1):
        result *= i
    return result

Check running results

cProfile.run('fact(126000)')

4 function calls in 4.708 seconds

Or Using builtin function math

That is for removing any space that is when you getting text from any text field but if you want to remove space between string you can use

xyz =[xyz.text stringByReplacingOccurrencesOfString:@" " withString:@""];

It will replace empty space with no space and empty field is taken care of by below method:

searchbar.text=[searchbar.text stringByTrimmingCharactersInSet: [NSCharacterSet whitespaceCharacterSet]];

The HTML5 history spec is quirky.

history.pushState() doesn't dispatch a popstate event or load a new page by itself. It was only meant to push state into history. This is an "undo" feature for single page applications. You have to manually dispatch a popstate event or use history.go() to navigate to the new state. The idea is that a router can listen to popstate events and do the navigation for you.

Some things to note:

• history.pushState() and history.replaceState() don't dispatch popstate events.
• history.back(), history.forward(), and the browser's back and forward buttons do dispatch popstate events.
• history.go() and history.go(0) do a full page reload and don't dispatch popstate events.
• history.go(-1) (back 1 page) and history.go(1) (forward 1 page) do dispatch popstate events.

You can use the history API like this to push a new state AND dispatch a popstate event.

history.pushState({message:'New State!'}, 'New Title', '/link'); window.dispatchEvent(new PopStateEvent('popstate', { bubbles: false, cancelable: false, state: history.state }));

Then listen for popstate events with a router.

There is no difference, in browsers that you can find in the wild these days (that is, excluding things like Netscape 1 that you might find in a museum). There is no reason to suspect that any of them would be deprecated ever, especially since they are all valid in XML, in HTML 4.01, and in HTML5 CR.

There is no reason to use any of them, as opposite to using the Ascii quotation mark (") directly, except in the very special case where you have an attribute value enclosed in such marks and you would like to use the mark inside the value (e.g., title="Hello "world""), and even then, there are almost always better options (like title='Hello "word"' or title="Hello “word”".

If you want to use “smart” quotation marks instead, then it’s a different question, and none of the constructs has anything to do with them. Some people expect notations like " to produce “smart” quotes, but it is easy to see that they don’t; the notations unambiguously denote the Ascii quote ("), as used in computer languages.

As suggested above, I just opened up the Postgres App on my Mac, clicked Open Psql, closed the psql window, restarted my rails server in my terminal, and it was working again, no more error.

I used to dislike std::for_each and thought that without lambda, it was done utterly wrong. However I did change my mind some time ago, and now I actually love it. And I think it even improves readability, and makes it easier to test your code in a TDD way.

The std::for_each algorithm can be read as do something with all elements in range, which can improve readability. Say the action that you want to perform is 20 lines long, and the function where the action is performed is also about 20 lines long. That would make a function 40 lines long with a conventional for loop, and only about 20 with std::for_each, thus likely easier to comprehend.

Functors for std::for_each are more likely to be more generic, and thus reusable, e.g:

struct DeleteElement
{
    template <typename T>
    void operator()(const T *ptr)
    {
        delete ptr;
    }
};

And in the code you'd only have a one-liner like std::for_each(v.begin(), v.end(), DeleteElement()) which is slightly better IMO than an explicit loop.

All of those functors are normally easier to get under unit tests than an explicit for loop in the middle of a long function, and that alone is already a big win for me.

std::for_each is also generally more reliable, as you're less likely to make a mistake with range.

And lastly, compiler might produce slightly better code for std::for_each than for certain types of hand-crafted for loop, as it (for_each) always looks the same for compiler, and compiler writers can put all of their knowledge, to make it as good as they can.

Same applies to other std algorithms like find_if, transform etc.

A good resource start off point would be MSDN as your looking into a microsoft product

Also be advised, that while Java is in general very beginner friendly, getting into JavaEE, Servlets, Facelets, Eclipse integration, JSP and getting everything in Tomcat up and running is not. Certainly not the easiest way to build a website and probably way overkill for most things.

On top of that you may need to host your website yourself, because most webspace providers don't provide Servlet Containers. If you just want to check it out for fun, I would try Ruby or Python, which are much more cooler things to fiddle around with. But anyway, to provide at least something relevant to the question, here's a nice Servlet tutorial: link

You can't set the value of a file input in the markup, like you did with value="123".

Update:

http://gitlab.org/ is another alternative now as well.

Update 2:

Gitorious has now joined with GitLab

Missing Context file location in configuration can cause this, one approach to solve this:

• Specifying Context file location in ContextConfiguration

like:

@ContextConfiguration(locations = { "classpath:META-INF/your-spring-context.xml" })

More details

@RunWith( SpringJUnit4ClassRunner.class )
@ContextConfiguration(locations = { "classpath:META-INF/your-spring-context.xml" })
public class UserServiceTest extends AbstractJUnit4SpringContextTests {}

Reference:Thanks to @Xstian

Try this:

 declare @MyFloatVal float;

    set @MyFloatVal=(select convert(decimal(10, 2), 10.254000))

    select  @MyFloatVal

    Convert(decimal(18,2),r.AdditionAmount) as AdditionAmount

More simple way...:

    Dim dt As DataTable = DirectCast(GridView1.DataSource, DataTable)
    Dim dv As New DataView(dt)

    If GridView1.Attributes("dir") = SortDirection.Ascending Then
        dv.Sort = e.SortExpression & " DESC" 
        GridView1.Attributes("dir") = SortDirection.Descending

    Else
        GridView1.Attributes("dir") = SortDirection.Ascending
        dv.Sort = e.SortExpression & " ASC"

    End If

    GridView1.DataSource = dv
    GridView1.DataBind()

There are several ways to achieve this.

The first option is easier, but bit more inefficient.

Override getItemPosition in your PagerAdapter like this:

public int getItemPosition(Object object) {
    return POSITION_NONE;
}

This way, when you call notifyDataSetChanged(), the view pager will remove all views and reload them all. As so the reload effect is obtained.

The second option, suggested by Alvaro Luis Bustamante (previously alvarolb), is to setTag() method in instantiateItem() when instantiating a new view. Then instead of using notifyDataSetChanged(), you can use findViewWithTag() to find the view you want to update.

The second approach is very flexible and high performant. Kudos to alvarolb for the original research.

The $http legacy promise methods success and error have been deprecated. Use the standard then method instead. Have a look at the docs https://docs.angularjs.org/api/ng/service/$http

Now the right way to use is:

// Simple GET request example:
$http({
  method: 'GET',
  url: '/someUrl'
}).then(function successCallback(response) {
    // this callback will be called asynchronously
    // when the response is available
  }, function errorCallback(response) {
    // called asynchronously if an error occurs
    // or server returns response with an error status.
});

The response object has these properties:

• data – {string|Object} – The response body transformed with the transform functions.
• status – {number} – HTTP status code of the response.
• headers – {function([headerName])} – Header getter function.
• config – {Object} – The configuration object that was used to generate the request.
• statusText – {string} – HTTP status text of the response.

A response status code between 200 and 299 is considered a success status and will result in the success callback being called.

You cannot use the Directory directive in .htaccess. However if you create a .htaccess file in the /system directory and place the following in it, you will get the same result

#place this in /system/.htaccess as you had before
deny from all

simply assign a variable to () or " ", then when needed type

print(x, x, x, Hello World, x)

or something like that.

Hope this is a little less complicated:)

You can control the data returned from SQL database by ordering the data returned:

orderby [Name]

If you execute the SQL query from your application, order the data returned. For example, make a function that calls the procedure or executes the SQL and give it a parameter that gets the orderby criteria. Because if you ordered the data returned from database it will consume time but order it since it's executed as you say that you want it to be ordered not from the UI you want it to be ordered in the run time so order it when executing the SQL query.

Update

I later found that, there is an official way to see all the routes, by going to http://localhost:3000/rails/info/routes. Official docs: https://guides.rubyonrails.org/routing.html#listing-existing-routes

Though, it may be late, But I love the error page which displays all the routes. I usually try to go at /routes (or some bogus) path directly from the browser. Rails server automatically gives me a routing error page as well as all the routes and paths defined. That was very helpful :)

So, Just go to http://localhost:3000/routes

The on-heap store refers to objects that will be present in the Java heap (and also subject to GC). On the other hand, the off-heap store refers to (serialized) objects that are managed by EHCache, but stored outside the heap (and also not subject to GC). As the off-heap store continues to be managed in memory, it is slightly slower than the on-heap store, but still faster than the disk store.

The internal details involved in management and usage of the off-heap store aren't very evident in the link posted in the question, so it would be wise to check out the details of Terracotta BigMemory, which is used to manage the off-disk store. BigMemory (the off-heap store) is to be used to avoid the overhead of GC on a heap that is several Megabytes or Gigabytes large. BigMemory uses the memory address space of the JVM process, via direct ByteBuffers that are not subject to GC unlike other native Java objects.

WHERE `column` LIKE '%$needle%'

If you want to literally use the method code from A and B you can make your C class contain an instance of each. If you code against interfaces for A and B then your clients don't need to know you're giving them a C rather than an A or a B.

interface IA { void SomeMethodOnA(); }
interface IB { void SomeMethodOnB(); }
class A : IA { void SomeMethodOnA() { /* do something */ } }
class B : IB { void SomeMethodOnB() { /* do something */ } }
class C : IA, IB
{
    private IA a = new A();
    private IB b = new B();
    void SomeMethodOnA() { a.SomeMethodOnA(); }
    void SomeMethodOnB() { b.SomeMethodOnB(); }
}

there are actually industry standards for widths (well according to yahoo at least). Their supported widths are 750, 950, 974, 100%

There are advantages of these widths for their predefined grids (column layouts) which work well with standard dimensions for advertisements if you were to include any.

Interesting talk too worth watching.

see YUI Base

In Python 2,

type(instance).__name__ != instance.__class__.__name__
# if class A is defined like
class A():
   ...

type(instance) == instance.__class__
# if class A is defined like
class A(object):
  ...

Example:

>>> class aclass(object):
...   pass
...
>>> a = aclass()
>>> type(a)
<class '__main__.aclass'>
>>> a.__class__
<class '__main__.aclass'>
>>>
>>> type(a).__name__
'aclass'
>>>
>>> a.__class__.__name__
'aclass'
>>>


>>> class bclass():
...   pass
...
>>> b = bclass()
>>>
>>> type(b)
<type 'instance'>
>>> b.__class__
<class __main__.bclass at 0xb765047c>
>>> type(b).__name__
'instance'
>>>
>>> b.__class__.__name__
'bclass'

You can use a background image to accomplish this;

From MDN - Background Size: Contain:

This keyword specifies that the background image should be scaled to be as large as possible while ensuring both its dimensions are less than or equal to the corresponding dimensions of the background positioning area.

Demo

CSS:

#im {
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    background-image: url("path/to/img");
    background-repeat: no-repeat;
    background-size: contain;
}

HTML:

<div id="wrapper">
    <div id="im">
    </div>
</div>

you are trying to set the 10th element of the array to the array try

data = new int[] {10,20,30,40,50,60,71,80,90,91};

FTFY

With the arrival of the HTTPClient API, not only was the Http API replaced, but a new one was added, the HttpInterceptor API.

AFAIK one of its goals is to add default behavior to all the HTTP outgoing requests and incoming responses.

So assumming that you want to add a default error handling behavior, adding .catch() to all of your possible http.get/post/etc methods is ridiculously hard to maintain.

This could be done in the following way as example using a HttpInterceptor:

import { Injectable } from '@angular/core';
import { HttpEvent, HttpInterceptor, HttpHandler, HttpRequest, HttpErrorResponse, HTTP_INTERCEPTORS } from '@angular/common/http';
import { Observable } from 'rxjs/Observable';
import { _throw } from 'rxjs/observable/throw';
import 'rxjs/add/operator/catch';

/**
 * Intercepts the HTTP responses, and in case that an error/exception is thrown, handles it
 * and extract the relevant information of it.
 */
@Injectable()
export class ErrorInterceptor implements HttpInterceptor {
    /**
     * Intercepts an outgoing HTTP request, executes it and handles any error that could be triggered in execution.
     * @see HttpInterceptor
     * @param req the outgoing HTTP request
     * @param next a HTTP request handler
     */
    intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
        return next.handle(req)
            .catch(errorResponse => {
                let errMsg: string;
                if (errorResponse instanceof HttpErrorResponse) {
                    const err = errorResponse.message || JSON.stringify(errorResponse.error);
                    errMsg = `${errorResponse.status} - ${errorResponse.statusText || ''} Details: ${err}`;
                } else {
                    errMsg = errorResponse.message ? errorResponse.message : errorResponse.toString();
                }
                return _throw(errMsg);
            });
    }
}

/**
 * Provider POJO for the interceptor
 */
export const ErrorInterceptorProvider = {
    provide: HTTP_INTERCEPTORS,
    useClass: ErrorInterceptor,
    multi: true,
};

// app.module.ts

import { ErrorInterceptorProvider } from 'somewhere/in/your/src/folder';

@NgModule({
   ...
   providers: [
    ...
    ErrorInterceptorProvider,
    ....
   ],
   ...
})
export class AppModule {}

Some extra info for OP: Calling http.get/post/etc without a strong type isn't an optimal use of the API. Your service should look like this:

// These interfaces could be somewhere else in your src folder, not necessarily in your service file
export interface FooPost {
 // Define the form of the object in JSON format that your 
 // expect from the backend on post
}

export interface FooPatch {
 // Define the form of the object in JSON format that your 
 // expect from the backend on patch
}

export interface FooGet {
 // Define the form of the object in JSON format that your 
 // expect from the backend on get
}

@Injectable()
export class DataService {
    baseUrl = 'http://localhost'
    constructor(
        private http: HttpClient) {
    }

    get(url, params): Observable<FooGet> {

        return this.http.get<FooGet>(this.baseUrl + url, params);
    }

    post(url, body): Observable<FooPost> {
        return this.http.post<FooPost>(this.baseUrl + url, body);
    }

    patch(url, body): Observable<FooPatch> {
        return this.http.patch<FooPatch>(this.baseUrl + url, body);
    }
}

Returning Promises from your service methods instead of Observables is another bad decision.

And an extra piece of advice: if you are using TYPEscript, then start using the type part of it. You lose one of the biggest advantages of the language: to know the type of the value that you are dealing with.

If you want a, in my opinion, good example of an angular service, take a look at the following gist.

Session["YourItem"] = "";

Works great in .net razor web pages.

This is simple program showing append('t') to the list.
n=['f','g','h','i','k']

for i in range(1):
    temp=[]
    temp.append(n[-2:])
    temp.append('t')
    print(temp)

Output: [['i', 'k'], 't']

Assuming that your objects are all of a similar type you could add a method as a category of their base class that calls the function you're using for your criteria. Then create an NSPredicate object that refers to that method.

In some category define your method that uses your function

@implementation BaseClass (SomeCategory)
- (BOOL)myMethod {
    return someComparisonFunction(self, whatever);
}
@end

Then wherever you'll be filtering:

- (NSArray *)myFilteredObjects {
    NSPredicate *pred = [NSPredicate predicateWithFormat:@"myMethod = TRUE"];
    return [myArray filteredArrayUsingPredicate:pred];
}

Of course, if your function only compares against properties reachable from within your class it may just be easier to convert the function's conditions to a predicate string.

Since no one seemed to be using NSDateComponents, I thought I would pitch one in... In this version, no NSDateFormatter is used, hence no string parsing, and NSDate is not used to represent time outside of GMT (UTC). The original NSDate is in the variable i_date.

NSCalendar *anotherCalendar = [[NSCalendar alloc] initWithCalendarIdentifier:i_anotherCalendar];
anotherCalendar.timeZone = [NSTimeZone timeZoneWithName:i_anotherTimeZone];

NSDateComponents *anotherComponents = [anotherCalendar components:(NSCalendarUnitEra | NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitDay | NSCalendarUnitHour | NSCalendarUnitMinute | NSCalendarUnitSecond | NSCalendarUnitNanosecond) fromDate:i_date];

// The following is just for checking   
anotherComponents.calendar = anotherCalendar; // anotherComponents.date is nil without this
NSDate *anotherDate = anotherComponents.date;

i_anotherCalendar could be NSCalendarIdentifierGregorian or any other calendar. The NSString allowed for i_anotherTimeZone can be acquired with [NSTimeZone knownTimeZoneNames], but anotherCalendar.timeZone could be [NSTimeZone defaultTimeZone] or [NSTimeZone localTimeZone] or [NSTimeZone systemTimeZone] altogether.

It is actually anotherComponents holding the time in the new time zone. You'll notice anotherDate is equal to i_date, because it holds time in GMT (UTC).

In my case, I had the variable named "AWS_PROFILE" on Environment variables with an old value.

Works fine for me, please try:

.scroll-container {
  max-height: 250px;
  overflow: auto;
  -webkit-overflow-scrolling: touch;
}

here is the example using Pure JavaScript

function scrollpage() {  _x000D_
 function f() _x000D_
 {_x000D_
  window.scrollTo(0,i);_x000D_
  if(status==0) {_x000D_
      i=i+40;_x000D_
   if(i>=Height){ status=1; } _x000D_
  } else {_x000D_
   i=i-40;_x000D_
   if(i<=1){ status=0; }  // if you don't want continue scroll then remove this line_x000D_
  }_x000D_
 setTimeout( f, 0.01 );_x000D_
 }f();_x000D_
}_x000D_
var Height=document.documentElement.scrollHeight;_x000D_
var i=1,j=Height,status=0;_x000D_
scrollpage();_x000D_
</script>

<style type="text/css">_x000D_
_x000D_
 #top { border: 1px solid black;  height: 20000px; }_x000D_
 #bottom { border: 1px solid red; }_x000D_
_x000D_
</style>

An alternative method to finding out the amount of rows in a dataframe which I think is the most readable variant is pandas.Index.size.

Do note that, as I commented on the accepted answer,

Suspected pandas.Index.size would actually be faster than len(df.index) but timeit on my computer tells me otherwise (~150 ns slower per loop).

This is an old question and you might have got the answer already.

My plnkr explains on my approach to accomplish selecting a default dropdown value. Basically, I have a service which would return the dropdown values [hard coded to test]. I was not able to select the value by default and almost spend a day and finally figured out that I should have set $scope.proofGroupId = "47"; instead of $scope.proofGroupId = 47; in the script.js file. It was my bad and I did not notice that I was setting an integer 47 instead of the string "47". I retained the plnkr as it is just in case if some one would like to see. Hopefully, this would help some one.

I found an easy way to run Visual Studio as administrator. I did it in windows 10 but I believe it would work on any windows.

1. Go to Start Menu
2. Search Visual Studio
3. Right Click on Visual Studio
4. Run As administrator

It turns out the best solution for me here was to just reformat the drive. Once reformatted all these problems were no longer problems.

I have the same error and it fixed it including in the file the following

#include <stdint.h>

at the beginning of your file.

Boost has something to help: the Boost.Iterator library.

More precisely this page: boost::iterator_adaptor.

What's very interesting is the Tutorial Example which shows a complete implementation, from scratch, for a custom type.

template <class Value>
class node_iter
  : public boost::iterator_adaptor<
        node_iter<Value>                // Derived
      , Value*                          // Base
      , boost::use_default              // Value
      , boost::forward_traversal_tag    // CategoryOrTraversal
    >
{
 private:
    struct enabler {};  // a private type avoids misuse

 public:
    node_iter()
      : node_iter::iterator_adaptor_(0) {}

    explicit node_iter(Value* p)
      : node_iter::iterator_adaptor_(p) {}

    // iterator convertible to const_iterator, not vice-versa
    template <class OtherValue>
    node_iter(
        node_iter<OtherValue> const& other
      , typename boost::enable_if<
            boost::is_convertible<OtherValue*,Value*>
          , enabler
        >::type = enabler()
    )
      : node_iter::iterator_adaptor_(other.base()) {}

 private:
    friend class boost::iterator_core_access;
    void increment() { this->base_reference() = this->base()->next(); }
};

The main point, as has been cited already, is to use a single template implementation and typedef it.

Make SymbolIndexer( const SymbolIndexer& ) private. If you're assigning to a reference, you're not copying.

Are you ssh'ing to a directory that's inside your work tree? If the root of your ssh mount point doesn't include the .git dir, then zsh won't be able to find git info. Make sure you're mounting something that includes the root of the repo.

As for GIT_DISCOVERY_ACROSS_FILESYSTEM, it doesn't do what you want. Git by default will stop at a filesystem boundary. If you turn that on (and it's just an env var), then git will cross the filesystem boundary and keep looking. However, that's almost never useful, because you'd be implying that you have a .git directory on your local machine that's somehow meant to manage a work tree that's comprised partially of an sshfs mount. That doesn't make much sense.

Try figsize param in df.plot(figsize=(width,height)):

df = pd.DataFrame({"a":[1,2],"b":[1,2]})
df.plot(figsize=(3,3));

df = pd.DataFrame({"a":[1,2],"b":[1,2]})
df.plot(figsize=(5,3));

The size in figsize=(5,3) is given in inches per (width, height)

For Sequelize 4

Query

SELECT * FROM Student WHERE LastName='Doe' 
AND (FirstName = "John" or FirstName = "Jane") AND Age BETWEEN 18 AND 24 

Syntax with Operators

const Op = require('Sequelize').Op;

var r = await to (Student.findAll(
{
  where: {
    LastName: "Doe",
    FirstName: {
      [Op.or]: ["John", "Jane"]
    },
    Age: {
      // [Op.gt]: 18
      [Op.between]: [18, 24]
    }
  }
}
));

Notes

• For better security Sequelize recommends dropping alias operators $ (e.g $and, $or ...)
• Unless you have {freezeTableName: true} set in the table model then Sequelize will query against the plural form of its name ( Student -> Students )

I think I got what I was looking for..

data.train <- read.table("Assign2.WineComplete.csv",sep=",",header=T)
fit <- rpart(quality ~ ., method="class",data=data.train)
plot(fit)
text(fit, use.n=TRUE)
summary(fit)

The collections don't maintain order of insertion. Some just default to add a new value at the end. Maintaining order of insertion is only useful if you prioritize the objects by it or use it to sort objects in some way.

As for why some collections maintain it by default and others don't, this is mostly caused by the implementation and only sometimes part of the collections definition.

• Lists maintain insertion order as just adding a new entry at the end or the beginning is the fastest implementation of the add(Object ) method.

• Sets The HashSet and TreeSet implementations don't maintain insertion order as the objects are sorted for fast lookup and maintaining insertion order would require additional memory. This results in a performance gain since insertion order is almost never interesting for Sets.

• ArrayDeque a deque can used for simple que and stack so you want to have ''first in first out'' or ''first in last out'' behaviour, both require that the ArrayDeque maintains insertion order. In this case the insertion order is maintained as a central part of the classes contract.

I had the same. Script been underlined. I added a reference to System.Web.Extensions. Thereafter the Script was no longer underlined. Hope this helps someone.

The answer is pretty much never. IDs are mainly used internally to Python.

The average Python programmer will probably never need to use id() in their code.

If your are going to replace all of the connection strings with news ones for production environment, you can simply replace all connection strings with production ones using this syntax:

<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">

<connectionStrings xdt:Transform="Replace">
    <!-- production environment config --->
    <add name="ApplicationServices" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnetdb.mdf;User Instance=true"
      providerName="System.Data.SqlClient" />
    <add name="Testing1" connectionString="Data Source=test;Initial Catalog=TestDatabase;Integrated Security=True"
      providerName="System.Data.SqlClient" />
</connectionStrings>
....

Information for this answer are brought from this answer and this blog post.

notice: As others explained already, this setting will apply only when application publishes not when running/debugging it (by hitting F5).

Within a module, to have a combination of flavors, flavor resources (layout, values) and flavors resource resources, the main thing to keep in mind are two things:

1. When adding resource directories in res.srcDirs for flavor, keep in mind that in other modules and even in src/main/res of the same module, resource directories are also added. Hence, the importance of using an add-on assignment (+=) so as not to overwrite all existing resources with the new assignment.

2. The path that is declared as an element of the array is the one that contains the resource types, that is, the resource types are all the subdirectories that a res folder contains normally such as color, drawable, layout, values, etc. The name of the res folder can be changed.

An example would be to use the path "src/flavor/res/values/strings-ES" but observe that the practice hierarchy has to have the subdirectory values:

+-- module 
   +-- flavor
      +-- res
         +-- values
            +-- strings-ES
               +-- values
                  +-- strings.xml
               +-- strings.xml
 

The framework recognizes resources precisely by type, that is why normally known subdirectories cannot be omitted.

Also keep in mind that all the strings.xml files that are inside the flavor would form a union so that resources cannot be duplicated. And in turn this union that forms a file in the flavor has a higher order of precedence before the main of the module.

flavor {
        res.srcDirs += [
            "src/flavor/res/values/strings-ES"
        ]
}

Consider the strings-ES directory as a custom-res which contains the resource types.

1. What is the difference between connection and read timeout for sockets?

The connection timeout is the timeout in making the initial connection; i.e. completing the TCP connection handshake. The read timeout is the timeout on waiting to read data¹. If the server (or network) fails to deliver any data <timeout> seconds after the client makes a socket read call, a read timeout error will be raised.

2. What does connection timeout set to "infinity" mean? In what situation can it remain in an infinitive loop? and what can trigger that the infinity-loop dies?

It means that the connection attempt can potentially block for ever. There is no infinite loop, but the attempt to connect can be unblocked by another thread closing the socket. (A Thread.interrupt() call may also do the trick ... not sure.)

3. What does read timeout set to "infinity" mean? In what situation can it remain in an infinite loop? What can trigger that the infinite loop to end?

It means that a call to read on the socket stream may block for ever. Once again there is no infinite loop, but the read can be unblocked by a Thread.interrupt() call, closing the socket, and (of course) the other end sending data or closing the connection.

^{1 - It is not ... as one commenter thought ... the timeout on how long a socket can be open, or idle.}

Not necessarily better, but since it's nice to have options here's how to do it using Jinja statements:

- debug:
    msg: "{% for address in network.addresses.private_man %}\
        {% if address.type == 'fixed' %}\
          {{ address.addr }}\
        {% endif %}\
      {% endfor %}"

Or if you prefer to put it all on one line:

- debug:
    msg: "{% for address in network.addresses.private_man if address.type == 'fixed' %}{{ address.addr }}{% endfor %}"

Which returns:

ok: [localhost] => {
    "msg": "172.16.1.100"
}

To change even less on your original query, you can turn your join into a RIGHT join

SELECT person.person_id, COUNT(appointment.person_id) AS "number_of_appointments"
FROM appointment
RIGHT JOIN person ON person.person_id = appointment.person_id
GROUP BY person.person_id;

This just builds on the selected answer, but as the outer join is in the RIGHT direction, only one word needs to be added and less changes. - Just remember that it's there and can sometimes make queries more readable and require less rebuilding.

I know there isn't any need to add a plugin for this.

But this can be useful if you are doing so many things with numbers. So checkout this plugin at least for a knowledge point of view.

The rest of karim79's answer is super cool.

I have used this way and Its a best forever. In this code null also handled

SELECT Title,
FirstName,
lastName, 
ISNULL(Title,'') + ' ' + ISNULL(FirstName,'') + ' ' + ISNULL(LastName,'') as FullName 
FROM Customer

Try this...

Years later, another one is below. But for everyday use I just

np.set_printoptions( threshold=20, edgeitems=10, linewidth=140,
    formatter = dict( float = lambda x: "%.3g" % x ))  # float arrays %.3g

''' printf( "... %.3g ... %.1f  ...", arg, arg ... ) for numpy arrays too

Example:
    printf( """ x: %.3g   A: %.1f   s: %s   B: %s """,
                   x,        A,        "str",  B )

If `x` and `A` are numbers, this is like `"format" % (x, A, "str", B)` in python.
If they're numpy arrays, each element is printed in its own format:
    `x`: e.g. [ 1.23 1.23e-6 ... ]  3 digits
    `A`: [ [ 1 digit after the decimal point ... ] ... ]
with the current `np.set_printoptions()`. For example, with
    np.set_printoptions( threshold=100, edgeitems=3, suppress=True )
only the edges of big `x` and `A` are printed.
`B` is printed as `str(B)`, for any `B` -- a number, a list, a numpy object ...

`printf()` tries to handle too few or too many arguments sensibly,
but this is iffy and subject to change.

How it works:
numpy has a function `np.array2string( A, "%.3g" )` (simplifying a bit).
`printf()` splits the format string, and for format / arg pairs
    format: % d e f g
    arg: try `np.asanyarray()`
-->  %s  np.array2string( arg, format )
Other formats and non-ndarray args are left alone, formatted as usual.

Notes:

`printf( ... end= file= )` are passed on to the python `print()` function.

Only formats `% [optional width . precision] d e f g` are implemented,
not `%(varname)format` .

%d truncates floats, e.g. 0.9 and -0.9 to 0; %.0f rounds, 0.9 to 1 .
%g is the same as %.6g, 6 digits.
%% is a single "%" character.

The function `sprintf()` returns a long string. For example,
    title = sprintf( "%s  m %g  n %g  X %.3g",
                    __file__, m, n, X )
    print( title )
    ...
    pl.title( title )

Module globals:
_fmt = "%.3g"  # default for extra args
_squeeze = np.squeeze  # (n,1) (1,n) -> (n,) print in 1 line not n

The title attribute displays a tooltip when the mouse is hovering the element. While this is a great addition, it doesn't help people who cannot use the mouse (due to mobility disabilities) or people who can't see this tooltip (e.g.: people with visual disabilities or people who use a screen reader).

As such, the mindful approach here would be to serve all users. I would add both title and aria-label attributes (serving different types of users and different types of usage of the web).

Here's a good article that explains aria-label in depth

Yes, via the text-overflow property in CSS 3. Caveat: it is not universally supported yet in browsers.

I always have to look this one up time and time again, so here is my answer.

Asserting multiple method calls on different objects of the same class

Suppose we have a heavy duty class (which we want to mock):

In [1]: class HeavyDuty(object):
   ...:     def __init__(self):
   ...:         import time
   ...:         time.sleep(2)  # <- Spends a lot of time here
   ...:     
   ...:     def do_work(self, arg1, arg2):
   ...:         print("Called with %r and %r" % (arg1, arg2))
   ...:  

here is some code that uses two instances of the HeavyDuty class:

In [2]: def heavy_work():
   ...:     hd1 = HeavyDuty()
   ...:     hd1.do_work(13, 17)
   ...:     hd2 = HeavyDuty()
   ...:     hd2.do_work(23, 29)
   ...:    

Now, here is a test case for the heavy_work function:

In [3]: from unittest.mock import patch, call
   ...: def test_heavy_work():
   ...:     expected_calls = [call.do_work(13, 17),call.do_work(23, 29)]
   ...:     
   ...:     with patch('__main__.HeavyDuty') as MockHeavyDuty:
   ...:         heavy_work()
   ...:         MockHeavyDuty.return_value.assert_has_calls(expected_calls)
   ...:  

We are mocking the HeavyDuty class with MockHeavyDuty. To assert method calls coming from every HeavyDuty instance we have to refer to MockHeavyDuty.return_value.assert_has_calls, instead of MockHeavyDuty.assert_has_calls. In addition, in the list of expected_calls we have to specify which method name we are interested in asserting calls for. So our list is made of calls to call.do_work, as opposed to simply call.

Exercising the test case shows us it is successful:

In [4]: print(test_heavy_work())
None

If we modify the heavy_work function, the test fails and produces a helpful error message:

In [5]: def heavy_work():
   ...:     hd1 = HeavyDuty()
   ...:     hd1.do_work(113, 117)  # <- call args are different
   ...:     hd2 = HeavyDuty()
   ...:     hd2.do_work(123, 129)  # <- call args are different
   ...:     

In [6]: print(test_heavy_work())
---------------------------------------------------------------------------
(traceback omitted for clarity)

AssertionError: Calls not found.
Expected: [call.do_work(13, 17), call.do_work(23, 29)]
Actual: [call.do_work(113, 117), call.do_work(123, 129)]

Asserting multiple calls to a function

To contrast with the above, here is an example that shows how to mock multiple calls to a function:

In [7]: def work_function(arg1, arg2):
   ...:     print("Called with args %r and %r" % (arg1, arg2))

In [8]: from unittest.mock import patch, call
   ...: def test_work_function():
   ...:     expected_calls = [call(13, 17), call(23, 29)]    
   ...:     with patch('__main__.work_function') as mock_work_function:
   ...:         work_function(13, 17)
   ...:         work_function(23, 29)
   ...:         mock_work_function.assert_has_calls(expected_calls)
   ...:    

In [9]: print(test_work_function())
None

There are two main differences. The first one is that when mocking a function we setup our expected calls using call, instead of using call.some_method. The second one is that we call assert_has_calls on mock_work_function, instead of on mock_work_function.return_value.

How about a NuGet Windows Identity Foundation. Just add it you you project and away you go! Its one of the MS owned NuGets so should be maintained accordingly.

EDIT: In Windows 8 Windows Identity Foundation is installed (enabled) by turning a windows feature on in Control Panel > All Control Panel Items > Programs and Features > Turn Windows feature on or off the feature is Windows Identity Foundation 3.5. Installers linked in the answer above will not work on Windows 8

I activated the Apache module headers a2enmod headers, and the issue has been solved.

Hard & Fast Rule

If all you need to do is add, subtract or multiply the numbers you are storing, DECIMAL is best.

If you need to divide or do any other form of arithmetic or algebra on the data you're almost certainly going to be happier with float. Floating point libraries, and on Intel processors, the floating point processor itself, have TONs of operations to correct, fix-up, detect and handle the blizzard of exceptions that occur when doing typical math functions - especially transcendental functions.

As for accuracy, I once wrote a budget system that computed the % contribution of each of 3,000+ accounts, for 3,600 budget units, by month to that unit's consolidation node, then based on that matrix of percentages (3,000 + x 12 x 3,600) I multiplied the amounts budgeted by the highest organizational nodes down to the next 3 levels of the organizational nodes, and then computed all (3,000 + 12) values for all 3,200 detail units from that. Millions and millions and millions of double precision floating point calculations, any one of which would throw off the roll-up of all of those projections in a bottoms-up consolidation back to the highest level in the organization.

The total floating point error after all of those calculations was ZERO. That was in 1986, and floating point libraries today are much, much better than they were back then. Intel does all of it's intermediate calculations of doubles in 80 bit precision, which all but eliminates rounding error. When someone tells you "it's floating point error" it's almost certainty NOT true.

Every method (other than a constructor) must have a return type.

public double diameter(){...

reinterpret_cast

declare @T table(Roles xml)

insert into @T values
('<root>
   <role>Alpha</role>
   <role>Beta</role>
   <role>Gamma</role>
</root>')

declare @Role varchar(10)

set @Role = 'Beta'

select Roles
from @T
where Roles.exist('/root/role/text()[. = sql:variable("@Role")]') = 1

If you want the query to work as where col like '%Beta%' you can use contains

declare @T table(Roles xml)

insert into @T values
('<root>
   <role>Alpha</role>
   <role>Beta</role>
   <role>Gamma</role>
</root>')

declare @Role varchar(10)

set @Role = 'et'

select Roles
from @T
where Roles.exist('/root/role/text()[contains(., sql:variable("@Role"))]') = 1

Maybe you need some dependency injection

public class Alpha {

    private Beta cbeta;

    public Alpha(Beta beta) {
        this.cbeta = beta;
    }

    public void DoSomethingAlpha() {
        this.cbeta.DoSomethingBeta();
    }
}

and then

Alpha cAlpha = new Alpha(new Beta());   

In large 24/7 or 24/6 systems -- systems that react to messages, RPC requests or that poll a database or process continuously -- it is useful to have a way to identify memory leaks. For this, I tend to add a mechanism to the application to temporarily suspend any processing and then perform full garbage collection. This puts the system into a quiescent state where the memory remaining is either legitimately long lived memory (caches, configuration, &c.) or else is 'leaked' (objects that are not expected or desired to be rooted but actually are).

Having this mechanism makes it a lot easier to profile memory usage as the reports will not be clouded with noise from active processing.

To be sure you get all of the garbage, you need to perform two collections:

GC.Collect();
GC.WaitForPendingFinalizers();
GC.Collect();

As the first collection will cause any objects with finalizers to be finalized (but not actually garbage collect these objects). The second GC will garbage collect these finalized objects.

var dataString = "flag=fetchmediaaudio&id="+id;

$.ajax
({
  type: "POST",
  url: "ajax.php",
  data: dataString,
  success: function(html)
  {
     alert(html);
  }
});

Do you mean something like this?

In [39]: df2.pivot_table(values='X', rows='Y', cols='Z', 
                         aggfunc=lambda x: len(x.unique()))
Out[39]: 
Z   Z1  Z2  Z3
Y             
Y1   1   1 NaN
Y2 NaN NaN   1

Note that using len assumes you don't have NAs in your DataFrame. You can do x.value_counts().count() or len(x.dropna().unique()) otherwise.

well this worked for me:

pip install mysqlclient

this is for python 3.x in window 7 i am not sure about other windows os versions

It is ternary operator, like an if/else statement.

if(a > b) {
what to do;
}
else {
what to do;
}

In ternary operator it is like that: condition ? what to do if condition is true : what to do if it is false;

(a > b) ? what to do if true : what to do if false;

Beware that when the mounted event is fired on a component, not all Vue components are replaced yet, so the DOM may not be final yet.

To really simulate the DOM onload event, i.e. to fire after the DOM is ready but before the page is drawn, use vm.$nextTick from inside mounted:

mounted: function () {
  this.$nextTick(function () {
    // Will be executed when the DOM is ready
  })
}

Instead of running perror on any error code you get, you can retrieve a complete listing of errno values on your system with the following one-liner:

cpp -dM /usr/include/errno.h | grep 'define E' | sort -n -k 3

While this can't be achieved with CSS/HTML alone, it can be achieved with JavaScript (without need of a library):

var textareas = document.getElementsByTagName('textarea');

for (i=0;i<textareas.length;i++){
    // you can omit the 'if' if you want to style the parent node regardless of its
    // element type
    if (textareas[i].parentNode.tagName.toString().toLowerCase() == 'div') {
        textareas[i].onfocus = function(){
            this.parentNode.style.borderStyle = 'solid';
        }
        textareas[i].onblur = function(){
            this.parentNode.style.borderStyle = 'dashed';
        }
    }
}

JS Fiddle demo.

Incidentally, with a library, such as jQuery, the above could be condensed down to:

$('textarea').focus(
    function(){
        $(this).parent('div').css('border-style','solid');
    }).blur(
    function(){
        $(this).parent('div').css('border-style','dashed');
    });

I am late for this Answer, but i just want to share what i did, which is basically the easiest solution

First of all-> Go to your info.plist File and add Status Bar Style->Transparent Black Style(Alpha of 0.5)

Now ,here it Goes:-

Add this code in your AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
    {
     //Whatever your code goes here
  if(kDeviceiPad){

     //adding status bar for IOS7 ipad
         if (IS_IOS7) {
              UIView *addStatusBar = [[UIView alloc] init];
              addStatusBar.frame = CGRectMake(0, 0, 1024, 20);
              addStatusBar.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:1]; //change this to match your navigation bar
              [self.window.rootViewController.view addSubview:addStatusBar];
                    }
                }
    else{

         //adding status bar for IOS7 iphone
        if (IS_IOS7) {
            UIView *addStatusBar = [[UIView alloc] init];
            addStatusBar.frame = CGRectMake(0, 0, 320, 20);
            addStatusBar.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:1]; //You can give your own color pattern
            [self.window.rootViewController.view addSubview:addStatusBar];
        }

    return YES;
   }

Read the doc:

In general, php://input should be used instead of $HTTP_RAW_POST_DATA.

as in the php Manual

What about:

datetime.now().strftime('%M:%S.%f')[:-4]

I'm not sure what you mean by "Milliseconds only 2 digits", but this should keep it to 2 decimal places. There may be a more elegant way by manipulating the strftime format string to cut down on the precision as well -- I'm not completely sure.

EDIT

If the %f modifier doesn't work for you, you can try something like:

now=datetime.now()
string_i_want=('%02d:%02d.%d'%(now.minute,now.second,now.microsecond))[:-4]

Again, I'm assuming you just want to truncate the precision.

PDOStatement->execute() can throw an exception

so what you can do is

try
{
PDOStatement->execute();
//record inserted
}
catch(Exception $e)
{
//Some error occured. (i.e. violation of constraints)
}

If you want to use small inline commands in the onclick tag you could go with something like this.

<button id="" class="delete" onclick="javascript:if(confirm('Are you sure you want to delete this entry?')){jQuery(this).parent().remove(); return false;}" type="button"> Delete </button>

Sorry, now I've read what you expected better, so I'm updating the answer.

Based on the HTML5 Specs from W3C, nothing is wrong. I created this JSFiddle test and it's behaving correctly based on the specs (for those browsers based on the specs, like Chrome 11 and Firefox 4):

<form>_x000D_
    <input type="checkbox" name="q" id="a-0" required autofocus>_x000D_
    <label for="a-0">a-1</label>_x000D_
    <br>_x000D_
_x000D_
    <input type="checkbox" name="q" id="a-1" required>_x000D_
    <label for="a-1">a-2</label>_x000D_
    <br>_x000D_
_x000D_
    <input type="checkbox" name="q" id="a-2" required>_x000D_
    <label for="a-2">a-3</label>_x000D_
    <br>_x000D_
_x000D_
    <input type="submit">_x000D_
</form>

I agree that it isn't very usable (in fact many people have complained about it in the W3C's mailing lists).

But browsers are just following the standard's recommendations, which is correct. The standard is a little misleading, but we can't do anything about it in practice. You can always use JavaScript for form validation, though, like some great jQuery validation plugin.

Another approach would be choosing a polyfill that can make (almost) all browsers interpret form validation rightly.

Just for reference's sake. This is how to do it with JQuery (useful for instance when you cannot query by element id):

$('#iframe').get(0).contentWindow.document.body.innerHTML

To prevent the flex items from shrinking, set the flex shrink factor to 0:

The flex shrink factor determines how much the flex item will shrink relative to the rest of the flex items in the flex container when negative free space is distributed. When omitted, it is set to 1.

You have a couple of options here, I think.

One would be to use a BackgroundWorker. This is a common helper for multithreading in applications. It exposes a DoWork event which is handled on a background thread from the Thread Pool and a RunWorkerCompleted event which is invoked back on the main thread when the background thread completes. It also has the benefit of try/catching the code running on the background thread so that an unhandled exception doesn't kill the application.

If you don't want to go that route, you can use the WPF dispatcher object to invoke an action to update the GUI back onto the main thread. Random reference:

http://www.switchonthecode.com/tutorials/working-with-the-wpf-dispatcher

There are many other options around too, but these are the two most common that come to mind.

These files are user-specific options, which should be independent of the solution itself. Visual Studio will create new ones as necessary, so they do not need to be checked in to source control. Indeed, it would probably be better not to as this allows individual developers to customize their environment as they see fit.

1> You can add image from layout itself:

<ImageView
                android:id="@+id/iv_your_image"
                android:layout_width="wrap_content"
                android:layout_height="25dp"
                android:background="@mipmap/your_image"
                android:padding="2dp" />

OR

2> Programmatically in java class:

ImageView ivYouImage= (ImageView)findViewById(R.id.iv_your_image);
        ivYouImage.setImageResource(R.mipmap.ic_changeImage);

OR for fragments:

View rowView= inflater.inflate(R.layout.your_layout, null, true);

ImageView ivYouImage= (ImageView) rowView.findViewById(R.id.iv_your_image);
        ivYouImage.setImageResource(R.mipmap.ic_changeImage);

Go to someplace the namespace is declared in one of your files. Put the cursor on the part of the namespace you want to change, and press F2. This should rename the namespace in every file. At least, it worked in my little demo project I created to test this answer!

Depending on your VS version, the shortcut might also be Ctrl-R,Ctrl-R.

You should always refrain from increasing the timeouts, I doubt your backend server response time is the issue here in any case.

I got around this issue by clearing the connection keep-alive flag and specifying http version as per the answer here: https://stackoverflow.com/a/36589120/479632

server {
    location / {
        proxy_set_header   X-Real-IP $remote_addr;
        proxy_set_header   Host      $http_host;

        # these two lines here
        proxy_http_version 1.1;
        proxy_set_header Connection "";

        proxy_pass http://localhost:5000;
    }
}

Unfortunately I can't explain why this works and didn't manage to decipher it from the docs mentioned in the answer linked either so if anyone has an explanation I'd be very interested to hear it.

In their simplest form, reset resets the index without touching the working tree, while checkout changes the working tree without touching the index.

Resets the index to match HEAD, working tree left alone:

git reset

Conceptually, this checks out the index into the working tree. To get it to actually do anything you would have to use -f to force it to overwrite any local changes. This is a safety feature to make sure that the "no argument" form isn't destructive:

git checkout

Once you start adding parameters it is true that there is some overlap.

checkout is usually used with a branch, tag or commit. In this case it will reset HEAD and the index to the given commit as well as performing the checkout of the index into the working tree.

Also, if you supply --hard to reset you can ask reset to overwrite the working tree as well as resetting the index.

If you current have a branch checked out out there is a crucial different between reset and checkout when you supply an alternative branch or commit. reset will change the current branch to point at the selected commit whereas checkout will leave the current branch alone but will checkout the supplied branch or commit instead.

Other forms of reset and commit involve supplying paths.

If you supply paths to reset you cannot supply --hard and reset will only change the index version of the supplied paths to the version in the supplied commit (or HEAD if you don't specify a commit).

If you supply paths to checkout, like reset it will update the index version of the supplied paths to match the supplied commit (or HEAD) but it will always checkout the index version of the supplied paths into the working tree.

What @BoltClock mentioned are pretty solid. And Here I just want to add several more solutions for this problem. check this w3c_collapsing margin. The green parts are the potential thought how this problem can be solved.

Solution 1

Margins between a floated box and any other box do not collapse (not even between a float and its in-flow children).

that means I can add float:left to either #outer or #inner demo1.

also notice that float would invalidate the auto in margin.

Solution 2

Margins of elements that establish new block formatting contexts (such as floats and elements with 'overflow' other than 'visible') do not collapse with their in-flow children.

other than visible, let's put overflow: hidden into #outer. And this way seems pretty simple and decent. I like it.

#outer{
    width: 500px;
    height: 200px;
    background: #FFCCCC;
    margin: 50px auto;
    overflow: hidden;
}
#inner {
    background: #FFCC33;
    height: 50px;
    margin: 50px;
}

Solution 3

Margins of absolutely positioned boxes do not collapse (not even with their in-flow children).

#outer{
    width: 500px;
    height: 200px;
    background: #FFCCCC;
    margin: 50px auto;
    position: absolute; 
}
#inner{
    background: #FFCC33;
    height: 50px;
    margin: 50px;
}

or

#outer{
    width: 500px;
    height: 200px;
    background: #FFCCCC;
    margin: 50px auto;
    position: relative; 
}
#inner {
    background: #FFCC33;
    height: 50px;
    margin: 50px;
    position: absolute;
}

these two methods will break the normal flow of div

Solution 4

Margins of inline-block boxes do not collapse (not even with their in-flow children).

Solution 5

The bottom margin of an in-flow block-level element always collapses with the top margin of its next in-flow block-level sibling, unless that sibling has clearance.

This has not much work to do with the question since it is the collapsing margin between siblings. it generally means if a top-box has margin-bottom: 30px and a sibling-box has margin-top: 10px. The total margin between them is 30px instead of 40px.

Solution 6

The top margin of an in-flow block element collapses with its first in-flow block-level child's top margin if the element has no top border, no top padding, and the child has no clearance.

This is very interesting and I can just add one top border line

#outer{
    width: 500px;
    height: 200px;
    background: #FFCCCC;
    margin: 50px auto;
    border-top: 1px solid red;

}
#inner {
    background: #FFCC33;
    height: 50px;
    margin: 50px;

}

And Also <div> is block-level in default, so you don't have to declare it on purpose. Sorry for not being able to post more than 2 links and images due to my novice reputation. At least you know where the problem comes from next time you see something similar.

As you've discovered, you can't do that. You can do:

libtest_LIBS = 

...

if HAVE_CLIENT
libtest_LIBS += libclient.la
endif

if HAVE_SERVER
libtest_LIBS += libserver.la
endif

You are thinking in the right direction. Merge master with mobiledevicesupport continuously and merge mobiledevicesupport with master when mobiledevicesupport is stable. Each developer will have his own branch and can merge to and from either on master or mobiledevicesupport depending on their role.

You need to uninstall IIS (Internet Information Services) but the key thing here is to make sure you uninstall the Windows Process Activation Service or otherwise your ApplicationHost.config will be still around. When you uninstall WAS then your configuration will be cleaned up and you will truly start with a fresh new IIS (and all data/configuration will be lost).

1. you have to have a reference to the form object in order to access its elements
2. the elements have to be declared public in order for another class to access them
3. don't do this - your class has to know too much about how your form is implemented; do not expose form controls outside of the form class
4. instead, make public properties on your form to get/set the values you are interested in
5. post more details of what you want and why, it sounds like you may be heading off in a direction that is not consistent with good encapsulation practices

If you are using the Sun JVM, and are interested in the internal memory usage of the application (how much out of the allocated memory your app is using) I prefer to turn on the JVMs built-in garbage collection logging. You simply add -verbose:gc to the startup command.

From the Sun documentation:

The command line argument -verbose:gc prints information at every collection. Note that the format of the -verbose:gc output is subject to change between releases of the J2SE platform. For example, here is output from a large server application:

[GC 325407K->83000K(776768K), 0.2300771 secs]
[GC 325816K->83372K(776768K), 0.2454258 secs]
[Full GC 267628K->83769K(776768K), 1.8479984 secs]

Here we see two minor collections and one major one. The numbers before and after the arrow

325407K->83000K (in the first line)

indicate the combined size of live objects before and after garbage collection, respectively. After minor collections the count includes objects that aren't necessarily alive but can't be reclaimed, either because they are directly alive, or because they are within or referenced from the tenured generation. The number in parenthesis

(776768K) (in the first line)

is the total available space, not counting the space in the permanent generation, which is the total heap minus one of the survivor spaces. The minor collection took about a quarter of a second.

0.2300771 secs (in the first line)

Is it possible to use a .netrc file on Windows?

Yes: You must:

• define environment variable %HOME% (pre-Git 2.0, no longer needed with Git 2.0+)
• put a _netrc file in %HOME%

If you are using Windows 7/10, in a CMD session, type:

setx HOME %USERPROFILE%

and the %HOME% will be set to 'C:\Users\"username"'.
Go that that folder (cd %HOME%) and make a file called '_netrc'

Note: Again, for Windows, you need a '_netrc' file, not a '.netrc' file.

Its content is quite standard (Replace the <examples> with your values):

machine <hostname1>
login <login1>
password <password1>
machine <hostname2>
login <login2>
password <password2>

Luke mentions in the comments:

Using the latest version of msysgit on Windows 7, I did not need to set the HOME environment variable. The _netrc file alone did the trick.

This is indeed what I mentioned in "Trying to “install” github, .ssh dir not there":
git-cmd.bat included in msysgit does set the %HOME% environment variable:

@if not exist "%HOME%" @set HOME=%HOMEDRIVE%%HOMEPATH%
@if not exist "%HOME%" @set HOME=%USERPROFILE%

??? believes in the comments that "it seems that it won't work for http protocol"

However, I answered that netrc is used by curl, and works for HTTP protocol, as shown in this example (look for 'netrc' in the page): . Also used with HTTP protocol here: "_netrc/.netrc alternative to cURL".

A common trap with with netrc support on Windows is that git will bypass using it if an origin https url specifies a user name.

For example, if your .git/config file contains:

[remote "origin"]
     fetch = +refs/heads/*:refs/remotes/origin/*
     url = https://[email protected]/p/my-project/

Git will not resolve your credentials via _netrc, to fix this remove your username, like so:

[remote "origin"]
     fetch = +refs/heads/*:refs/remotes/origin/*
     url = https://code.google.com/p/my-project/

Alternative solution: With git version 1.7.9+ (January 2012): This answer from Mark Longair details the credential cache mechanism which also allows you to not store your password in plain text as shown below.

With Git 1.8.3 (April 2013):

You now can use an encrypted .netrc (with gpg).
On Windows: %HOME%/_netrc (_, not '.')

A new read-only credential helper (in contrib/) to interact with the .netrc/.authinfo files has been added.

That script would allow you to use gpg-encrypted netrc files, avoiding the issue of having your credentials stored in a plain text file.

Files with the .gpg extension will be decrypted by GPG before parsing.
Multiple -f arguments are OK. They are processed in order, and the first matching entry found is returned via the credential helper protocol.

When no -f option is given, .authinfo.gpg, .netrc.gpg, .authinfo, and .netrc files in your home directory are used in this order.

To enable this credential helper:

git config credential.helper '$shortname -f AUTHFILE1 -f AUTHFILE2'

(Note that Git will prepend "git-credential-" to the helper name and look for it in the path.)

# and if you want lots of debugging info:
git config credential.helper '$shortname -f AUTHFILE -d'

#or to see the files opened and data found:
git config credential.helper '$shortname -f AUTHFILE -v'

See a full example at "Is there a way to skip password typing when using https:// github"

With Git 2.18+ (June 2018), you now can customize the GPG program used to decrypt the encrypted .netrc file.

See commit 786ef50, commit f07eeed (12 May 2018) by Luis Marsano (``).

git-credential-netrc: accept gpg option

git-credential-netrc was hardcoded to decrypt with 'gpg' regardless of the gpg.program option.
This is a problem on distributions like Debian that call modern GnuPG something else, like 'gpg2'

It depends a bit on your version. Before 5.0.13 this is not possible with mysqldump.

From the mysqldump man page (v 5.1.30)

 --routines, -R

      Dump stored routines (functions and procedures) from the dumped
      databases. Use of this option requires the SELECT privilege for the
      mysql.proc table. The output generated by using --routines contains
      CREATE PROCEDURE and CREATE FUNCTION statements to re-create the
      routines. However, these statements do not include attributes such
      as the routine creation and modification timestamps. This means that
      when the routines are reloaded, they will be created with the
      timestamps equal to the reload time.
      ...

      This option was added in MySQL 5.0.13. Before that, stored routines
      are not dumped. Routine DEFINER values are not dumped until MySQL
      5.0.20. This means that before 5.0.20, when routines are reloaded,
      they will be created with the definer set to the reloading user. If
      you require routines to be re-created with their original definer,
      dump and load the contents of the mysql.proc table directly as
      described earlier.

Put this line into your vimrc:

set nobk nowb noswf noudf " nobackup nowritebackup noswapfile noundofile

In windows that would be the:

C:\Program Files (x86)\vim\_vimrc

file for system-wide vim configuration for all users.

Setting the last one noundofile is important in Windows to prevent the creation of *~ tilda files after editing.

I wish Vim had that line included by default. Nobody likes ugly directories.

Let the user choose if and how she wants to enable advanced backup/undo file features first.

This is the most annoying part of Vim.

The next step might be setting up:

set noeb vb t_vb= " errorbells visualbell

to disable beeping in vim as well :-)

Here is a very nifty way.

First format the content such that the column to be compared for uniqueness is a fixed width. One way of doing this is to use awk printf with a field/column width specifier ("%15s").

Now the -f and -w options of uniq can be used to skip preceding fields/columns and to specify the comparison width (column(s) width).

Here are three examples.

In the first example...

1) Temporarily make the column of interest a fixed width greater than or equal to the field's max width.

2) Use -f uniq option to skip the prior columns, and use the -w uniq option to limit the width to the tmp_fixed_width.

3) Remove trailing spaces from the column to "restore" it's width (assuming there were no trailing spaces beforehand).

printf "%s" "$str" \
| awk '{ tmp_fixed_width=15; uniq_col=8; w=tmp_fixed_width-length($uniq_col); for (i=0;i<w;i++) { $uniq_col=$uniq_col" "}; printf "%s\n", $0 }' \
| uniq -f 7 -w 15 \
| awk '{ uniq_col=8; gsub(/ */, "", $uniq_col); printf "%s\n", $0 }'

In the second example...

Create a new uniq column 1. Then remove it after the uniq filter has been applied.

printf "%s" "$str" \
| awk '{ uniq_col_1=4; printf "%15s %s\n", uniq_col_1, $0 }' \
| uniq -f 0 -w 15 \
| awk '{ $1=""; gsub(/^ */, "", $0); printf "%s\n", $0 }'

The third example is the same as the second, but for multiple columns.

printf "%s" "$str" \
| awk '{ uniq_col_1=4; uniq_col_2=8; printf "%5s %15s %s\n", uniq_col_1, uniq_col_2, $0 }' \
| uniq -f 0 -w 5 \
| uniq -f 1 -w 15 \
| awk '{ $1=$2=""; gsub(/^ */, "", $0); printf "%s\n", $0 }'

There is now a beta available of Google Maps KML Importing Utility.

It is part of the Google Maps Android API Utility Library. As documented it allows loading KML files from streams

KmlLayer layer = new KmlLayer(getMap(), kmlInputStream, getApplicationContext());

or local resources

KmlLayer layer = new KmlLayer(getMap(), R.raw.kmlFile, getApplicationContext());

After you have created a KmlLayer, call addLayerToMap() to add the imported data onto the map.

layer.addLayerToMap();

the best way i found was to set the image you want to view responsively as a background image and sent a css property for the div as cover.

background-image : url('YOUR URL');

It seem to ignore the settings for the current active transaction, it only apply settings to a new transaction:

org.springframework.transaction.PlatformTransactionManager
TransactionStatus getTransaction(TransactionDefinition definition)
                         throws TransactionException
Return a currently active transaction or create a new one, according to the specified propagation behavior.
Note that parameters like isolation level or timeout will only be applied to new transactions, and thus be ignored when participating in active ones.
Furthermore, not all transaction definition settings will be supported by every transaction manager: A proper transaction manager implementation should throw an exception when unsupported settings are encountered.
An exception to the above rule is the read-only flag, which should be ignored if no explicit read-only mode is supported. Essentially, the read-only flag is just a hint for potential optimization.

Most likely, the problem is that you're using a relative file path to open the file, but the current working directory isn't set to what you think it is.

It's a common misconception that relative paths are relative to the location of the python script, but this is untrue. Relative file paths are always relative to the current working directory, and the current working directory doesn't have to be the location of your python script.

You have three options:

• Use an absolute path to open the file:

  file = open(r'C:\path\to\your\file.yaml')
  

• Generate the path to the file relative to your python script:

  from pathlib import Path
  
  script_location = Path(__file__).absolute().parent
  file_location = script_location / 'file.yaml'
  file = file_location.open()
  

  (See also: How do I get the path and name of the file that is currently executing?)

• Change the current working directory before opening the file:

  import os
  
  os.chdir(r'C:\path\to\your\file')
  file = open('file.yaml')
  

Other common mistakes that could cause a "file not found" error include:

• Accidentally using escape sequences in a file path:

  path = 'C:\Users\newton\file.yaml'
  # Incorrect! The '\n' in 'Users\newton' is a line break character!
  

  To avoid making this mistake, remember to use raw string literals for file paths:

  path = r'C:\Users\newton\file.yaml'
  # Correct!
  

  (See also: Windows path in Python)

• Forgetting that Windows doesn't display file extensions:

  Since Windows doesn't display known file extensions, sometimes when you think your file is named file.yaml, it's actually named file.yaml.yaml. Double-check your file's extension.

For some reason contents() didn't work for me, so if it didn't work for you, here's a solution I made, I created jQuery.fn.descendants with the option to include text nodes or not

Usage

Get all descendants including text nodes and element nodes

jQuery('body').descendants('all');

Get all descendants returning only text nodes

jQuery('body').descendants(true);

Get all descendants returning only element nodes

jQuery('body').descendants();

Coffeescript Original:

jQuery.fn.descendants = ( textNodes ) ->

    # if textNodes is 'all' then textNodes and elementNodes are allowed
    # if textNodes if true then only textNodes will be returned
    # if textNodes is not provided as an argument then only element nodes
    # will be returned

    allowedTypes = if textNodes is 'all' then [1,3] else if textNodes then [3] else [1]

    # nodes we find
    nodes = []


    dig = (node) ->

        # loop through children
        for child in node.childNodes

            # push child to collection if has allowed type
            nodes.push(child) if child.nodeType in allowedTypes

            # dig through child if has children
            dig child if child.childNodes.length


    # loop and dig through nodes in the current
    # jQuery object
    dig node for node in this


    # wrap with jQuery
    return jQuery(nodes)

Unminified Javascript version: http://pastebin.com/cX3jMfuD

This is cross browser, a small Array.indexOf polyfill is included in the code.

Since Python 3.5 this is finally no longer awkward:

>>> b'\xde\xad\xbe\xef'.hex()
'deadbeef'

and reverse:

>>> bytes.fromhex('deadbeef')
b'\xde\xad\xbe\xef'

works also with the mutable bytearray type.

All of these are returning equals. They arent actually doing a comparison, which is useful for sort. This will behave more like a comparator:

private static final Comparator stringFallbackComparator = new Comparator() {
    public int compare(Object o1, Object o2) {
        if (!(o1 instanceof Comparable))
            o1 = o1.toString();
        if (!(o2 instanceof Comparable))
            o2 = o2.toString();
        return ((Comparable)o1).compareTo(o2);
    }
};

public int compare(Map m1, Map m2) {
    TreeSet s1 = new TreeSet(stringFallbackComparator); s1.addAll(m1.keySet());
    TreeSet s2 = new TreeSet(stringFallbackComparator); s2.addAll(m2.keySet());
    Iterator i1 = s1.iterator();
    Iterator i2 = s2.iterator();
    int i;
    while (i1.hasNext() && i2.hasNext())
    {
        Object k1 = i1.next();
        Object k2 = i2.next();
        if (0!=(i=stringFallbackComparator.compare(k1, k2)))
            return i;
        if (0!=(i=stringFallbackComparator.compare(m1.get(k1), m2.get(k2))))
            return i;
    }
    if (i1.hasNext())
        return 1;
    if (i2.hasNext())
        return -1;
    return 0;
}

The keepNA = TRUE option prevents problems with NA

nchar(NA)
## [1] 2
nchar(NA, keepNA=TRUE)
## [1] NA

1 is substantially different from 2 and 3, since it leaves the array in tact, whereas the other two leave it empty.

I'd say #3 is pretty wacky and probably less efficient, so forget that.

Which leaves you with #1 and #2, and they do not do the same thing, so one cannot be "better" than the other. If the array is large and you don't need to keep it, generally scope will deal with it (but see NOTE), so generally, #1 is still the clearest and simplest method. Shifting each element off will not speed anything up. Even if there is a need to free the array from the reference, I'd just go:

undef @Array;

when done.

• NOTE: The subroutine containing the scope of the array actually keeps the array and re-uses the space next time. Generally, that should be fine (see comments).

ElementTree is not too smart about namespaces. You need to give the .find(), findall() and iterfind() methods an explicit namespace dictionary. This is not documented very well:

namespaces = {'owl': 'http://www.w3.org/2002/07/owl#'} # add more as needed

root.findall('owl:Class', namespaces)

Prefixes are only looked up in the namespaces parameter you pass in. This means you can use any namespace prefix you like; the API splits off the owl: part, looks up the corresponding namespace URL in the namespaces dictionary, then changes the search to look for the XPath expression {http://www.w3.org/2002/07/owl}Class instead. You can use the same syntax yourself too of course:

root.findall('{http://www.w3.org/2002/07/owl#}Class')

If you can switch to the lxml library things are better; that library supports the same ElementTree API, but collects namespaces for you in a .nsmap attribute on elements.

Use like this:

when(
  fooDao.getBar(
    Matchers.<Bazoo>any()
  )
).thenReturn(myFoo);

Before you need to import Mockito.Matchers

I'm guessing you're using the date_select helper to generate the tags for the date. Another way you could do it is to use select form helper for the day, month, year fields. Like this (example I used is the created_at date field):

<%= f.select :month, (1..12).to_a, selected: @user.created_at.month %>
<%= f.select :day, (1..31).to_a, selected: @user.created_at.day %>
<%= f.select :year, ((Time.now.year - 20)..Time.now.year).to_a, selected: @user.created_at.year %>

And in the model, you validate the date:

attr_accessor :month, :day, :year
validate :validate_created_at

private

def convert_created_at
  begin
    self.created_at = Date.civil(self.year.to_i, self.month.to_i, self.day.to_i)
  rescue ArgumentError
    false
  end
end

def validate_created_at
  errors.add("Created at date", "is invalid.") unless convert_created_at
end

If you're looking for a plugin solution, I'd checkout the validates_timeliness plugin. It works like this (from the github page):

class Person < ActiveRecord::Base
  validates_date :date_of_birth, on_or_before: lambda { Date.current }
  # or
  validates :date_of_birth, timeliness: { on_or_before: lambda { Date.current }, type: :date }
end 

The list of validation methods available are as follows:

validates_date     - validate value as date
validates_time     - validate value as time only i.e. '12:20pm'
validates_datetime - validate value as a full date and time
validates          - use the :timeliness key and set the type in the hash.

If you happened to run npm install command on Windows, first make sure you open your command prompt with Administration Privileges. That's what solved the issue for me.

Confusing messages

These messages are rather misleading and understandably a source of confusion. Older Ubuntu versions used Libav which is a fork of the FFmpeg project. FFmpeg returned in Ubuntu 15.04 "Vivid Vervet".

The fork was basically a non-amicable result of conflicting personalities and development styles within the FFmpeg community. It is worth noting that the maintainer for Debian/Ubuntu switched from FFmpeg to Libav on his own accord due to being involved with the Libav fork.

The real ffmpeg vs the fake one

For a while both Libav and FFmpeg separately developed their own version of ffmpeg.

Libav then renamed their bizarro ffmpeg to avconv to distance themselves from the FFmpeg project. During the transition period the "not developed anymore" message was displayed to tell users to start using avconv instead of their counterfeit version of ffmpeg. This confused users into thinking that FFmpeg (the project) is dead, which is not true. A bad choice of words, but I can't imagine Libav not expecting such a response by general users.

This message was removed upstream when the fake "ffmpeg" was finally removed from the Libav source, but, depending on your version, it can still show up in Ubuntu because the Libav source Ubuntu uses is from the ffmpeg-to-avconv transition period.

In June 2012, the message was re-worded for the package libav - 4:0.8.3-0ubuntu0.12.04.1. Unfortunately the new "deprecated" message has caused additional user confusion.

Starting with Ubuntu 15.04 "Vivid Vervet", FFmpeg's ffmpeg is back in the repositories again.

libav vs Libav

To further complicate matters, Libav chose a name that was historically used by FFmpeg to refer to its libraries (libavcodec, libavformat, etc). For example the libav-user mailing list, for questions and discussions about using the FFmpeg libraries, is unrelated to the Libav project.

How to tell the difference

If you are using avconv then you are using Libav. If you are using ffmpeg you could be using FFmpeg or Libav. Refer to the first line in the console output to tell the difference: the copyright notice will either mention FFmpeg or Libav.

Secondly, the version numbering schemes differ. Each of the FFmpeg or Libav libraries contains a version.h header which shows a version number. FFmpeg will end in three digits, such as 57.67.100, and Libav will end in one digit such as 57.67.0. You can also view the library version numbers by running ffmpeg or avconv and viewing the console output.

If you want to use the real ffmpeg

Ubuntu 15.04 "Vivid Vervet" or newer

The real ffmpeg is in the repository, so you can install it with:

apt-get install ffmpeg

For older Ubuntu versions

Your options are:

• Download a recent Linux build of ffmpeg,
• follow a step-by-step guide to compile ffmpeg,
• or use Doug McMahon's PPA (for Ubuntu 14.04 LTS "Trusty Tahr")

These methods are non-intrusive, reversible, and will not interfere with the system or any repository packages.

Another possible option is to upgrade to Ubuntu 15.04 "Vivid Vervet" or newer and just use ffmpeg from the repository.

grouper('ABCDEFG', 3, 'x') --> 'ABC' 'DEF' 'Gxx'

Note: on Python 2 use izip_longest instead of zip_longest.

It's simple, every time you open Jupyter Notebook and you are in your current work directory, open the Terminal in the near top right corner position where create new Python file in. The terminal in Jupyter will appear in the new tab. Type command cd <your new work directory> and enter, and then type Jupyter Notebook in that terminal, a new Jupyter Notebook will appear in the new tab with your new work directory.

Here is what I did to solve just by 2 ways:

1. make ID column as int type

2. if you are using autogenerate in ID dont assing value in the setter of ID. If your mapping the some then sometimes autogenetated ID is not concedered. (I dont know why)

3. try using @GeneratedValue(strategy=GenerationType.SEQUENCE) if possible

Passing no-sandbox to exec seems important for jenkins on windows in foreground or as service. Here's my solution

Since You Have used the float property we don't have many options except to adjust it manually.

The DateTime class takes a string in the constructor. If you prefix the timestamp with a @-character you create a DateTime object with the timestamp. For formating use the 'c' format ... a predefined ISO 8601 compound format.

If could use the DateTime class like this ... set the right timezone or leave it out if you want a UTC time.

$dt = new DateTime('@1333699439');
$dt->setTimezone(new DateTimeZone('America/New_York'));
echo $dt->format('c');

There's no guarantee that the content length you're provided is actually correct. Try something akin to the following:

ByteArrayOutputStream baos = new ByteArrayOutputStream();
InputStream is = null;
try {
  is = url.openStream ();
  byte[] byteChunk = new byte[4096]; // Or whatever size you want to read in at a time.
  int n;

  while ( (n = is.read(byteChunk)) > 0 ) {
    baos.write(byteChunk, 0, n);
  }
}
catch (IOException e) {
  System.err.printf ("Failed while reading bytes from %s: %s", url.toExternalForm(), e.getMessage());
  e.printStackTrace ();
  // Perform any other exception handling that's appropriate.
}
finally {
  if (is != null) { is.close(); }
}

You'll then have the image data in baos, from which you can get a byte array by calling baos.toByteArray().

This code is untested (I just wrote it in the answer box), but it's a reasonably close approximation to what I think you're after.

In PowerShell you can use the command Set-Service:

Set-Service -Name Winmgmt -StartupType Manual

I haven't found a PowerShell command to view the startup type though. One would assume that the command Get-Service would provide that, but it doesn't seem to.

Try this:

for view in container_view.subviews {
    view.removeFromSuperview()
}

# Autoload lib/ folder including all subdirectories
config.autoload_paths += Dir["#{config.root}/lib/**/"]

Please mind that files contained in the lib folder are only loaded when the server is started. If you want the comfort to autoreload those files, read: Rails 3 Quicktip: Auto reload lib folders in development mode. Be aware that this is not meant for a production environment since the permanent reload slows down the machine.

Common reasons for the error:

• use of assignment (=) instead of equality (==/===)
• assigning to result of function foo() = 42 instead of passing arguments (foo(42))
• simply missing member names (i.e. assuming some default selection) : getFoo() = 42 instead of getFoo().theAnswer = 42 or array indexing getArray() = 42 instead of getArray()[0]= 42

In this particular case you want to use == (or better === - What exactly is Type Coercion in Javascript?) to check for equality (like if(one === "rock" && two === "rock"), but it the actual reason you are getting the error is trickier.

The reason for the error is Operator precedence. In particular we are looking for && (precedence 6) and = (precedence 3).

Let's put braces in the expression according to priority - && is higher than = so it is executed first similar how one would do 3+4*5+6 as 3+(4*5)+6:

 if(one= ("rock" && two) = "rock"){...

Now we have expression similar to multiple assignments like a = b = 42 which due to right-to-left associativity executed as a = (b = 42). So adding more braces:

 if(one= (  ("rock" && two) = "rock" )  ){...

Finally we arrived to actual problem: ("rock" && two) can't be evaluated to l-value that can be assigned to (in this particular case it will be value of two as truthy).

Note that if you'd use braces to match perceived priority surrounding each "equality" with braces you get no errors. Obviously that also producing different result than you'd expect - changes value of both variables and than do && on two strings "rock" && "rock" resulting in "rock" (which in turn is truthy) all the time due to behavior of logial &&:

if((one = "rock") && (two = "rock"))
{
   // always executed, both one and two are set to "rock"
   ...
}

For even more details on the error and other cases when it can happen - see specification:

Those classes are common extension points for Java UI designs. First off, realize that they don't necessarily have much to do with each other directly, so trying to find a relationship between them might be counterproductive.

JApplet - A base class that let's you write code that will run within the context of a browser, like for an interactive web page. This is cool and all but it brings limitations which is the price for it playing nice in the real world. Normally JApplet is used when you want to have your own UI in a web page. I've always wondered why people don't take advantage of applets to store state for a session so no database or cookies are needed.

JComponent - A base class for objects which intend to interact with Swing.

JFrame - Used to represent the stuff a window should have. This includes borders (resizeable y/n?), titlebar (App name or other message), controls (minimize/maximize allowed?), and event handlers for various system events like 'window close' (permit app to exit yet?).

JPanel - Generic class used to gather other elements together. This is more important with working with the visual layout or one of the provided layout managers e.g. gridbaglayout, etc. For example, you have a textbox that is bigger then the area you have reserved. Put the textbox in a scrolling pane and put that pane into a JPanel. Then when you place the JPanel, it will be more manageable in terms of layout.

Regular Expressions are compiled before being used when using the second version. If you are going to executing it many times it is definatly better to compile it first. If not compiling every time you match for one off's is fine.

You can set a property on the form to do this for you if you have a button on the form that closes the form already.

Set the CancelButton property of the form to that button.

Gets or sets the button control that is clicked when the user presses the Esc key.

If you don't have a cancel button then you'll need to add a KeyDown handler and check for the Esc key in that:

private void Form_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Escape)
    {
        this.Close();
    }
}

You will also have to set the KeyPreview property to true.

Gets or sets a value indicating whether the form will receive key events before the event is passed to the control that has focus.

However, as Gargo points out in his answer this will mean that pressing Esc to abort an edit on a control in the dialog will also have the effect of closing the dialog. To avoid that override the ProcessDialogKey method as follows:

protected override bool ProcessDialogKey(Keys keyData)
{
    if (Form.ModifierKeys == Keys.None && keyData == Keys.Escape)
    {
        this.Close();
        return true;
    }
    return base.ProcessDialogKey(keyData);
}

I've reduced your code sample to the following lines to make it easier to understand the explanation of the concept.

var results = [];
var config = JSON.parse(queries);
for (var key in config) {
    var query = config[key].query;
    search(query, function(result) {
        results.push(result);
    });
}
res.writeHead( ... );
res.end(results);

The problem with the previous code is that the search function is asynchronous, so when the loop has ended, none of the callback functions have been called. Consequently, the list of results is empty.

To fix the problem, you have to put the code after the loop in the callback function.

    search(query, function(result) {
        results.push(result);
        // Put res.writeHead( ... ) and res.end(results) here
    });

However, since the callback function is called multiple times (once for every iteration), you need to somehow know that all callbacks have been called. To do that, you need to count the number of callbacks, and check whether the number is equal to the number of asynchronous function calls.

To get a list of all keys, use Object.keys. Then, to iterate through this list, I use .forEach (you can also use for (var i = 0, key = keys[i]; i < keys.length; ++i) { .. }, but that could give problems, see JavaScript closure inside loops – simple practical example).

Here's a complete example:

var results = [];
var config = JSON.parse(queries);
var onComplete = function() {
    res.writeHead( ... );
    res.end(results);
};
var keys = Object.keys(config);
var tasksToGo = keys.length;
if (tasksToGo === 0) {
   onComplete();
} else {
    // There is at least one element, so the callback will be called.
    keys.forEach(function(key) {
        var query = config[key].query;
        search(query, function(result) {
            results.push(result);
            if (--tasksToGo === 0) {
                // No tasks left, good to go
                onComplete();
            }
        });
    });
}

Note: The asynchronous code in the previous example are executed in parallel. If the functions need to be called in a specific order, then you can use recursion to get the desired effect:

var results = [];
var config = JSON.parse(queries);
var keys = Object.keys(config);
(function next(index) {
    if (index === keys.length) { // No items left
        res.writeHead( ... );
        res.end(results);
        return;
    }
    var key = keys[index];
    var query = config[key].query;
    search(query, function(result) {
        results.push(result);
        next(index + 1);
    });
})(0);

What I've shown are the concepts, you could use one of the many (third-party) NodeJS modules in your implementation, such as async.

Definition

A callback is executable code that is passed as an argument to other code.

Implementation

// Parent can Read
public class Parent
{
    public string Read(){ /*reads here*/ };
}

// Child need Info
public class Child
{
    private string information;
    // declare a Delegate
    delegate string GetInfo();
    // use an instance of the declared Delegate
    public GetInfo GetMeInformation;

    public void ObtainInfo()
    {
        // Child will use the Parent capabilities via the Delegate
        information = GetMeInformation();
    }
}

Usage

Parent Peter = new Parent();
Child Johny = new Child();

// Tell Johny from where to obtain info
Johny.GetMeInformation = Peter.Read;

Johny.ObtainInfo(); // here Johny 'asks' Peter to read

You need to handle it via ajax submit.

Something like this:

$(function(){
    $('#subscribe-email-form').on('submit', function(e){
        e.preventDefault();
        $.ajax({
            url: url, //this is the submit URL
            type: 'GET', //or POST
            data: $('#subscribe-email-form').serialize(),
            success: function(data){
                 alert('successfully submitted')
            }
        });
    });
});

A better way would be to use a django form, and then render the following snippet:

<form>
    <div class="modal-body">
        <input type="email" placeholder="email"/>
        <p>This service will notify you by email should any issue arise that affects your plivo service.</p>
    </div>
    <div class="modal-footer">
        <input type="submit" value="SUBMIT" class="btn"/>
    </div>
</form>

via the context - example : {{form}}.

You may try this way. just use a function to get your object

def get_object(self, id):
    try:
        return Comment.objects.get(pk=id)
    except Comment.DoesNotExist:
        return False

FAQ

Questions from the top of my head since that time I gone crazy with jacoco.

My application server (jBoss, Glassfish..) located in Iraq, Syria, whatever.. Is it possible to get multi-module coverage when running integration tests on it? Jenkins and Sonar are also on different servers.

Yes. You have to use jacoco agent that runs in mode output=tcpserver, jacoco ant lib. Basically two jars. This will give you 99% success.

How does jacoco agent works?

You append a string

-javaagent:[your_path]/jacocoagent.jar=destfile=/jacoco.exec,output=tcpserver,address=*

to your application server JAVA_OPTS and restart it. In this string only [your_path] have to be replaced with the path to jacocoagent.jar, stored(store it!) on your VM where app server runs. Since that time you start app server, all applications that are deployed will be dynamically monitored and their activity (meaning code usage) will be ready for you to get in jacocos .exec format by tcl request.

Could I reset jacoco agent to start collecting execution data only since the time my test start?

Yes, for that purpose you need jacocoant.jar and ant build script located in your jenkins workspace.

So basically what I need from http://www.eclemma.org/jacoco/ is jacocoant.jar located in my jenkins workspace, and jacocoagent.jar located on my app server VM?

That's right.

I don't want to use ant, I've heard that jacoco maven plugin can do all the things too.

That's not right, jacoco maven plugin can collect unit test data and some integration tests data(see Arquillian Jacoco), but if you have for example rest assured tests as a separated build in jenkins, and want to show multi-module coverage, I can't see how maven plugin can help you.

What exactly does jacoco agent produce?

Only coverage data in .exec format. Sonar then can read it.

Does jacoco need to know where my java classes located are?

No, sonar does, but not jacoco. When you do mvn sonar:sonar path to classes comes into play.

So what about the ant script?

It has to be presented in your jenkins workspace. Mine ant script, I called it jacoco.xml looks like that:

<project name="Jacoco library to collect code coverage remotely" xmlns:jacoco="antlib:org.jacoco.ant">
    <property name="jacoco.port" value="6300"/>
    <property name="jacocoReportFile" location="${workspace}/it-jacoco.exec"/>

    <taskdef uri="antlib:org.jacoco.ant" resource="org/jacoco/ant/antlib.xml">
        <classpath path="${workspace}/tools/jacoco/jacocoant.jar"/>
    </taskdef>

    <target name="jacocoReport">
            <jacoco:dump address="${jacoco.host}" port="${jacoco.port}" dump="true" reset="true" destfile="${jacocoReportFile}" append="false"/>
    </target>

    <target name="jacocoReset">
            <jacoco:dump address="${jacoco.host}" port="${jacoco.port}" reset="true" destfile="${jacocoReportFile}" append="false"/>
        <delete file="${jacocoReportFile}"/>
    </target>
</project>

Two mandatory params you should pass when invoking this script -Dworkspace=$WORKSPACE use it to point to your jenkins workspace and -Djacoco.host=yourappserver.com host without http://

Also notice that I put my jacocoant.jar to ${workspace}/tools/jacoco/jacocoant.jar

What should I do next?

Did you start your app server with jacocoagent.jar?

Did you put ant script and jacocoant.jar in your jenkins workspace?

If yes the last step is to configure a jenkins build. Here is the strategy:

1. Invoke ant target jacocoReset to reset all previously collected data.
2. Run your tests
3. Invoke ant target jacocoReport to get report

If everything is right, you will see it-jacoco.exec in your build workspace.

Look at the screenshot, I also have ant installed in my workspace in $WORKSPACE/tools/ant dir, but you can use one that is installed in your jenkins.

How to push this report in sonar?

Maven sonar:sonar will do the job (don't forget to configure it), point it to main pom.xml so it will run through all modules. Use sonar.jacoco.itReportPath=$WORKSPACE/it-jacoco.exec parameter to tell sonar where your integration test report is located. Every time it will analyse new module classes, it will look for information about coverage in it-jacoco.exec.

I already have jacoco.exec in my `target` dir, `mvn sonar:sonar` ignores/removes it

By default mvn sonar:sonar does clean and deletes your target dir, use sonar.dynamicAnalysis=reuseReports to avoid it.

docker rmi docker images -a | grep "<none>" | awk {'print $3'}

Firstly run this query

SHOW VARIABLES LIKE '%char%';

You have character_set_server='latin1'

If so,go into your config file,my.cnf and add or uncomment these lines:

character-set-server = utf8
collation-server = utf8_unicode_ci

Restart the server. Yes late to the party,just encountered the same issue.

Notice that in most suggestions the initial random value that you have got from rand() function, which is typically from 0 to RAND_MAX, is simply wasted. You are creating only one random number out of it, while there is a sound procedure that can give you more.

Assume that you want [min,max] region of integer random numbers. We start from [0, max-min]

Take base b=max-min+1

Start from representing a number you got from rand() in base b.

That way you have got floor(log(b,RAND_MAX)) because each digit in base b, except possibly the last one, represents a random number in the range [0, max-min].

Of course the final shift to [min,max] is simple for each random number r+min.

int n = NUM_DIGIT-1;
while(n >= 0)
{
    r[n] = res % b;
    res -= r[n];
    res /= b;
    n--;
}

If NUM_DIGIT is the number of digit in base b that you can extract and that is

NUM_DIGIT = floor(log(b,RAND_MAX))

then the above is as a simple implementation of extracting NUM_DIGIT random numbers from 0 to b-1 out of one RAND_MAX random number providing b < RAND_MAX.

I would recommend you to use worksheet's index instead of using worksheet's name, in this way you can also loop through sheets "dynamically"

for i=1 to thisworkbook.sheets.count
 sheets(i).activate
'You can add more code 
with activesheet
 'Code...
end with
next i

It will also, improve performance.

If you don't care about the columns where the missing files are, considering that the dataframe has the name New and one wants to assign the new dataframe to the same variable, simply run

New = New.drop_duplicates()

If you specifically want to remove the rows for the empty values in the column Tenant this will do the work

New = New[New.Tenant != '']

This may also be used for removing rows with a specific value - just change the string to the value that one wants.

Note: If instead of an empty string one has NaN, then

New = New.dropna(subset=['Tenant'])

You can also create a Docker container with Alpine as the OS and the install Python and Pyspark as packages. That will have it all containerised.

The simple way to use XMLHttpRequest with pure JavaScript. You can set custom header but it's optional used based on requirement.

1. Using POST Method:

window.onload = function(){
    var request = new XMLHttpRequest();
    var params = "UID=CORS&name=CORS";

    request.onreadystatechange = function() {
        if (this.readyState == 4 && this.status == 200) {
            console.log(this.responseText);
        }
    };

    request.open('POST', 'https://www.example.com/api/createUser', true);
    request.setRequestHeader('api-key', 'your-api-key');
    request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    request.send(params);
}

You can send params using POST method.

2. Using GET Method:

Please run below example and will get an JSON response.

window.onload = function(){_x000D_
    var request = new XMLHttpRequest();_x000D_
_x000D_
    request.onreadystatechange = function() {_x000D_
        if (this.readyState == 4 && this.status == 200) {_x000D_
            console.log(this.responseText);_x000D_
        }_x000D_
    };_x000D_
_x000D_
    request.open('GET', 'https://jsonplaceholder.typicode.com/users/1');_x000D_
    request.send();_x000D_
}

You can use Class.forName() to get a Class object of the desired class.

Then use getConstructor() to find the desired Constructor object.

Finally, call newInstance() on that object to get your new instance.

Class<?> c = Class.forName("mypackage.MyClass");
Constructor<?> cons = c.getConstructor(String.class);
Object object = cons.newInstance("MyAttributeValue");

http://jira.springframework.org/browse/SPR-6464 provided me with what I needed to get things working until Spring MVC offers the functionality (potentially in the 3.0.2 release). Although I simply implemented the classes they have temporarily and added the filter to my web application context. Works great!

Here the code to use your app.js

input specifies file name

res.download(__dirname+'/'+input);

The last part of the error message you quoted states: ...with ("checkPermission") or explicitly handle a potential "SecurityException"

A much quicker/simpler way of checking if you have permissions is to surround your code with try { ... } catch (SecurityException e) { [insert error handling code here] }. If you have permissions, the 'try' part will execute, if you don't, the 'catch' part will.

In VS Code, press Ctrl + Shift + F and enter your old package name in 'Find' and enter your new package in 'Replace'. Then press 'Replace all occurrences'.

Definitely not the pragmatic way. But, it's done the trick for me.

You just go to here to see if your pg version support Win32 platform, then use this command to install:

gem install pg -v 0.14.1 --platform=x86-mingw32

The numpy and scipy libraries include the composite trapezoidal (numpy.trapz) and Simpson's (scipy.integrate.simps) rules.

Here's a simple example. In both trapz and simps, the argument dx=5 indicates that the spacing of the data along the x axis is 5 units.

from __future__ import print_function

import numpy as np
from scipy.integrate import simps
from numpy import trapz


# The y values.  A numpy array is used here,
# but a python list could also be used.
y = np.array([5, 20, 4, 18, 19, 18, 7, 4])

# Compute the area using the composite trapezoidal rule.
area = trapz(y, dx=5)
print("area =", area)

# Compute the area using the composite Simpson's rule.
area = simps(y, dx=5)
print("area =", area)

Output:

area = 452.5
area = 460.0

Simplest way to add a separator line under each tableview cell can be done in the storyboard itself. First select the tableview, then in the attribute inspector select the separator line property to be single line. After this, select the separator inset to be custom and update the left inset to be 0 from the left.

Example
