If you only want to develop a single web service and have it hosted on many different endpoints (i.e. SOAP + REST, with XML, JSON, CSV, HTML outputes). You should also consider using ServiceStack which I've built for exactly this purpose where every service you develop is automatically available on on both SOAP and REST endpoints out-of-the-box without any configuration required.

The Hello World example shows how to create a simple with service with just (no config required):

public class Hello {
    public string Name { get; set; }
}

public class HelloResponse {
    public string Result { get; set; }
}

public class HelloService : IService
{
    public object Any(Hello request)
    {
        return new HelloResponse { Result = "Hello, " + request.Name };
    }
}

No other configuration is required, and this service is immediately available with REST in:

• SOAP
• XML
• JSON
• HTML

It also comes in-built with a friendly HTML output (when called with a HTTP client that has Accept:text/html e.g a browser) so you're able to better visualize the output of your services.

Handling different REST verbs are also as trivial, here's a complete REST-service CRUD app in 1 page of C# (less than it would take to configure WCF ;):

• Front-end TODO applicaiton
• Back-end REST Service implementation

Make sure your AndroidManifest file contains a package name in the manifest node. Setting a package name fixed this problem for me.

The name of CA file to use you could pass via verify:

cafile = 'cacert.pem' # http://curl.haxx.se/ca/cacert.pem
r = requests.get(url, verify=cafile)

If you use verify=True then requests uses its own CA set that might not have CA that signed your server certificate.

In selection formula try this

Date(Year({datetimefield}), Month({datetimefield}), Day({datetimefield}))

Try this

package main

import "fmt"
import "strconv"

func FloatToString(input_num float64) string {
    // to convert a float number to a string
    return strconv.FormatFloat(input_num, 'f', 6, 64)
}

func main() {
    fmt.Println(FloatToString(21312421.213123))
}

If you just want as many digits precision as possible, then the special precision -1 uses the smallest number of digits necessary such that ParseFloat will return f exactly. Eg

strconv.FormatFloat(input_num, 'f', -1, 64)

Personally I find fmt easier to use. (Playground link)

fmt.Printf("x = %.6f\n", 21312421.213123)

Or if you just want to convert the string

fmt.Sprintf("%.6f", 21312421.213123)

You can still do this in top. While top is running, press '1' on your keyboard, it will then show CPU usage per core.

Limit the processes shown by having that specific process run under a specific user account and use Type 'u' to limit to that user

I have answered on this.

In my case, the problem was because of Video Downloader professional and AdBlock

In short, this problem occurs due to some google chrome plugins

There is no maximum since Ruby 2.4, as Bignum and Fixnum got unified into Integer. see Feature #12005

> (2 << 1000).is_a? Fixnum
(irb):322: warning: constant ::Fixnum is deprecated
=> true

> 1.is_a? Bignum
(irb):314: warning: constant ::Bignum is deprecated
=> true

> (2 << 1000).class
=> Integer

There won't be any overflow, what would happen is an out of memory.

These steps worked on me:

1. write mongod --port 27017 on cmd
2. then connect to mongo shell : mongo --port 27017
3. create the user admin : use admin db.createUser( { user: "myUserAdmin", pwd: "abc123", roles: [ { role: "userAdminAnyDatabase", db: "admin" } ] } )
4. disconnect mongo shell
5. restart the mongodb : mongod --auth --port 27017
6. start mongo shell : mongo --port 27017 -u "myUserAdmin" -p "abc123" --authenticationDatabase "admin"
7. To authenticate after connecting, Connect the mongo shell to the mongod: mongo --port 27017
8. switch to the authentication database : use admin db.auth("myUserAdmin", "abc123"

Better to just use .addClass() and .removeClass() even if you have 1 or more styles to change. It's more maintainable and readable.

If you really have the urge to do multiple CSS properties, then use the following:

.css({
   'font-size' : '10px',
   'width' : '30px',
   'height' : '10px'
});

NB!
Any CSS properties with a hyphen need to be quoted.
I've placed the quotes so no one will need to clarify that, and the code will be 100% functional.

if b > 0:
    int mod = (mod = a % b) < 0 ? a + b : a;

Doesn't use the % operator twice.

After hours of searching and looking for answer, finally I made it!!!!! Code is below :))))

HTML:

<form id="fileinfo" enctype="multipart/form-data" method="post" name="fileinfo">
    <label>File to stash:</label>
    <input type="file" name="file" required />
</form>
<input type="button" value="Stash the file!"></input>
<div id="output"></div>

jQuery:

$(function(){
    $('#uploadBTN').on('click', function(){ 
        var fd = new FormData($("#fileinfo"));
        //fd.append("CustomField", "This is some extra data");
        $.ajax({
            url: 'upload.php',  
            type: 'POST',
            data: fd,
            success:function(data){
                $('#output').html(data);
            },
            cache: false,
            contentType: false,
            processData: false
        });
    });
});

In the upload.php file you can access the data passed with $_FILES['file'].

Thanks everyone for trying to help:)

I took the answer from here (with some changes) MDN

Short function to remove all non-numeric characters but keep the decimal (and return the number):

parseNum = str => +str.replace(/[^.\d]/g, '');_x000D_
let str = 'a1b2c.d3e';_x000D_
console.log(parseNum(str));

To my mind the case for a PT (as @Nathan Fisher) is a 'no brainer', but I would add a column to facilitate ordering by rank (up or down):

OPS is entered as VALUES (Sum of) twice so I have renamed the column labels to make clearer which is which. The PT is in a different sheet from the data but could be in the same sheet.

Rank is set with a right click on a data point selected in that column and Show Values As... and Rank Largest to Smallest (there are other options) with the Base field as Player and the filter is a Value Filters, Top 10... one:

Once in a PT the power of that feature can very easily be applied to view the data in many other ways, with no change of formula (there isn't one!).

In the case of a tie for the last position included in the filter both results are included (Top 5 would show six or more results). A tie for top rank between just two players would show as 1 1 3 4 5 for Top 5.

The NoSuchMethodError javadoc says this:

Thrown if an application tries to call a specified method of a class (either static or instance), and that class no longer has a definition of that method.

Normally, this error is caught by the compiler; this error can only occur at run time if the definition of a class has incompatibly changed.

In your case, this Error is a strong indication that your webapp is using the wrong version of the JAR defining the org.objectweb.asm.* classes.

You could do something like this also:

ol {
  font-weight: bold;
}

ol > li > * {
  font-weight: normal;
}

So you have no "style" attributes in your HTML

In C++11, the using keyword when used for type alias is identical to typedef.

7.1.3.2

A typedef-name can also be introduced by an alias-declaration. The identifier following the using keyword becomes a typedef-name and the optional attribute-specifier-seq following the identifier appertains to that typedef-name. It has the same semantics as if it were introduced by the typedef specifier. In particular, it does not define a new type and it shall not appear in the type-id.

Bjarne Stroustrup provides a practical example:

typedef void (*PFD)(double);    // C style typedef to make `PFD` a pointer to a function returning void and accepting double
using PF = void (*)(double);    // `using`-based equivalent of the typedef above
using P = [](double)->void; // using plus suffix return type, syntax error
using P = auto(double)->void // Fixed thanks to DyP

Pre-C++11, the using keyword can bring member functions into scope. In C++11, you can now do this for constructors (another Bjarne Stroustrup example):

class Derived : public Base { 
public: 
    using Base::f;    // lift Base's f into Derived's scope -- works in C++98
    void f(char);     // provide a new f 
    void f(int);      // prefer this f to Base::f(int) 

    using Base::Base; // lift Base constructors Derived's scope -- C++11 only
    Derived(char);    // provide a new constructor 
    Derived(int);     // prefer this constructor to Base::Base(int) 
    // ...
}; 

Ben Voight provides a pretty good reason behind the rationale of not introducing a new keyword or new syntax. The standard wants to avoid breaking old code as much as possible. This is why in proposal documents you will see sections like Impact on the Standard, Design decisions, and how they might affect older code. There are situations when a proposal seems like a really good idea but might not have traction because it would be too difficult to implement, too confusing, or would contradict old code.

Here is an old paper from 2003 n1449. The rationale seems to be related to templates. Warning: there may be typos due to copying over from PDF.

First let’s consider a toy example:

template <typename T>
class MyAlloc {/*...*/};

template <typename T, class A>
class MyVector {/*...*/};

template <typename T>

struct Vec {
typedef MyVector<T, MyAlloc<T> > type;
};
Vec<int>::type p; // sample usage

The fundamental problem with this idiom, and the main motivating fact for this proposal, is that the idiom causes the template parameters to appear in non-deducible context. That is, it will not be possible to call the function foo below without explicitly specifying template arguments.

template <typename T> void foo (Vec<T>::type&);

So, the syntax is somewhat ugly. We would rather avoid the nested ::type We’d prefer something like the following:

template <typename T>
using Vec = MyVector<T, MyAlloc<T> >; //defined in section 2 below
Vec<int> p; // sample usage

Note that we specifically avoid the term “typedef template” and introduce the new syntax involving the pair “using” and “=” to help avoid confusion: we are not defining any types here, we are introducing a synonym (i.e. alias) for an abstraction of a type-id (i.e. type expression) involving template parameters. If the template parameters are used in deducible contexts in the type expression then whenever the template alias is used to form a template-id, the values of the corresponding template parameters can be deduced – more on this will follow. In any case, it is now possible to write generic functions which operate on Vec<T> in deducible context, and the syntax is improved as well. For example we could rewrite foo as:

template <typename T> void foo (Vec<T>&);

We underscore here that one of the primary reasons for proposing template aliases was so that argument deduction and the call to foo(p) will succeed.

The follow-up paper n1489 explains why using instead of using typedef:

It has been suggested to (re)use the keyword typedef — as done in the paper [4] — to introduce template aliases:

template<class T> 
    typedef std::vector<T, MyAllocator<T> > Vec;

That notation has the advantage of using a keyword already known to introduce a type alias. However, it also displays several disavantages among which the confusion of using a keyword known to introduce an alias for a type-name in a context where the alias does not designate a type, but a template; Vec is not an alias for a type, and should not be taken for a typedef-name. The name Vec is a name for the family std::vector< [bullet] , MyAllocator< [bullet] > > – where the bullet is a placeholder for a type-name. Consequently we do not propose the “typedef” syntax. On the other hand the sentence

template<class T>
    using Vec = std::vector<T, MyAllocator<T> >;

can be read/interpreted as: from now on, I’ll be using Vec<T> as a synonym for std::vector<T, MyAllocator<T> >. With that reading, the new syntax for aliasing seems reasonably logical.

I think the important distinction is made here, aliases instead of types. Another quote from the same document:

An alias-declaration is a declaration, and not a definition. An alias- declaration introduces a name into a declarative region as an alias for the type designated by the right-hand-side of the declaration. The core of this proposal concerns itself with type name aliases, but the notation can obviously be generalized to provide alternate spellings of namespace-aliasing or naming set of overloaded functions (see ? 2.3 for further discussion). [My note: That section discusses what that syntax can look like and reasons why it isn't part of the proposal.] It may be noted that the grammar production alias-declaration is acceptable anywhere a typedef declaration or a namespace-alias-definition is acceptable.

Summary, for the role of using:

• template aliases (or template typedefs, the former is preferred namewise)
• namespace aliases (i.e., namespace PO = boost::program_options and using PO = ... equivalent)
• the document says A typedef declaration can be viewed as a special case of non-template alias-declaration. It's an aesthetic change, and is considered identical in this case.
• bringing something into scope (for example, namespace std into the global scope), member functions, inheriting constructors

It cannot be used for:

int i;
using r = i; // compile-error

Instead do:

using r = decltype(i);

Naming a set of overloads.

// bring cos into scope
using std::cos;

// invalid syntax
using std::cos(double);

// not allowed, instead use Bjarne Stroustrup function pointer alias example
using test = std::cos(double);

You can get a complete list of environment variables by running the command set from the command prompt.

To select by class, you can do this:

$("input.className:checkbox:not(:checked)")

Relying on compiler optimizations is fragile. The benchmarks linked in the accepted answer and numbers given by Antoine-tran are not to be trusted. Andrew Hare makes the mistake of including a call to repr in his methods. That slows all the methods equally but obscures the real penalty in constructing the string.

Use join. It's very fast and more robust.

Accidently I found a simple workaroud to this issue. Running Maven with -X option forces it to try other servers to download source code. Instead of trash HTML inside some jar files there is correct content.

mvn clean install -X > d:\log.txt

And in the log file you find messages like these:

Downloading: https://repository.apache.org/content/groups/public/org/apache/axis2/mex/1.6.1-wso2v2/mex-1.6.1-wso2v2-impl.jar

You see, Maven switched repository.apache.org to maven.wso2.org when it encountered a download problem. So the following error is now gone:

Java 8 provides different utility api methods to help us sort the streams better.

If your list is a list of Integers(or Double, Long, String etc.,) then you can simply sort the list with default comparators provided by java.

List<Integer> integerList = Arrays.asList(1, 4, 3, 4, 5);

Creating comparator on fly:

integerList.stream().sorted((i1, i2) -> i1.compareTo(i2)).forEach(System.out::println);

With default comparator provided by java 8 when no argument passed to sorted():

integerList.stream().sorted().forEach(System.out::println); //Natural order

If you want to sort the same list in reverse order:

 integerList.stream().sorted(Comparator.reverseOrder()).forEach(System.out::println); // Reverse Order

If your list is a list of user defined objects, then:

List<Person> personList = Arrays.asList(new Person(1000, "First", 25, 30000),
        new Person(2000, "Second", 30, 45000),
        new Person(3000, "Third", 35, 25000));

Creating comparator on fly:

personList.stream().sorted((p1, p2) -> ((Long)p1.getPersonId()).compareTo(p2.getPersonId()))
        .forEach(person -> System.out.println(person.getName()));

Using Comparator.comparingLong() method(We have comparingDouble(), comparingInt() methods too):

personList.stream().sorted(Comparator.comparingLong(Person::getPersonId)).forEach(person -> System.out.println(person.getName()));

Using Comparator.comparing() method(Generic method which compares based on the getter method provided):

personList.stream().sorted(Comparator.comparing(Person::getPersonId)).forEach(person -> System.out.println(person.getName()));

We can do chaining too using thenComparing() method:

personList.stream().sorted(Comparator.comparing(Person::getPersonId).thenComparing(Person::getAge)).forEach(person -> System.out.println(person.getName())); //Sorting by person id and then by age.

Person class

public class Person {
    private long personId;
    private String name;
    private int age;
    private double salary;

    public long getPersonId() {
        return personId;
    }

    public void setPersonId(long personId) {
        this.personId = personId;
    }

    public Person(long personId, String name, int age, double salary) {
        this.personId = personId;
        this.name = name;
        this.age = age;

        this.salary = salary;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public double getSalary() {
        return salary;
    }

    public void setSalary(double salary) {
        this.salary = salary;
    }
}

to have the camera write to sdcard but keep in a new Album on the gallery app I use this :

 File imageDirectory = new File("/sdcard/signifio");
          String path = imageDirectory.toString().toLowerCase();
           String name = imageDirectory.getName().toLowerCase();


            ContentValues values = new ContentValues(); 
            values.put(Media.TITLE, "Image"); 
            values.put(Images.Media.BUCKET_ID, path.hashCode());
            values.put(Images.Media.BUCKET_DISPLAY_NAME,name);

            values.put(Images.Media.MIME_TYPE, "image/jpeg");
            values.put(Media.DESCRIPTION, "Image capture by camera");
           values.put("_data", "/sdcard/signifio/1111.jpg");
         uri = getContentResolver().insert( Media.EXTERNAL_CONTENT_URI , values);
            Intent i = new Intent("android.media.action.IMAGE_CAPTURE"); 

            i.putExtra(MediaStore.EXTRA_OUTPUT, uri);

            startActivityForResult(i, 0); 

Please note that you will need to generate a unique filename every time and replace teh 1111.jpg that I wrote. This was tested with nexus one. the uri is declared in the private class , so on activity result I am able to load the image from the uri to imageView for preview if needed.

inet_ntoa() works for IPv4; inet_ntop() works for both IPv4 and IPv6.

Given an input struct sockaddr *res, here are two snippets of code (tested on macOS):

Using inet_ntoa()

#include <arpa/inet.h>

struct sockaddr_in *addr_in = (struct sockaddr_in *)res;
char *s = inet_ntoa(addr_in->sin_addr);
printf("IP address: %s\n", s);

Using inet_ntop()

#include <arpa/inet.h>
#include <stdlib.h>

char *s = NULL;
switch(res->sa_family) {
    case AF_INET: {
        struct sockaddr_in *addr_in = (struct sockaddr_in *)res;
        s = malloc(INET_ADDRSTRLEN);
        inet_ntop(AF_INET, &(addr_in->sin_addr), s, INET_ADDRSTRLEN);
        break;
    }
    case AF_INET6: {
        struct sockaddr_in6 *addr_in6 = (struct sockaddr_in6 *)res;
        s = malloc(INET6_ADDRSTRLEN);
        inet_ntop(AF_INET6, &(addr_in6->sin6_addr), s, INET6_ADDRSTRLEN);
        break;
    }
    default:
        break;
}
printf("IP address: %s\n", s);
free(s);

You can specify you format Gson gson = builder.setDateFormat("yyyy-MM-dd").create(); in this method instead of yyyy-MM-dd you can use anyother formats

 GsonBuilder builder = new GsonBuilder();
                        builder.registerTypeAdapter(Date.class, new JsonDeserializer<Date>() {
                            public Date deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws JsonParseException {
                                return new Date(json.getAsJsonPrimitive().getAsLong());
                            }
                        });

                        Gson gson = builder.setDateFormat("yyyy-MM-dd").create();

If you have pandas installed you can turn it into a series with the keys as the index. So something like

import pandas as pd

s = pd.Series(my_dict)

s[['key1', 'key3', 'key2']]

As far as I understand, you have more than one form tag in your web page that causes the problem. Make sure you have only one server-side form tag for each page.

Maybe this helps. You have to refer the @param

         /**       
         * Display a listing of the resource.
         *
         * @param  Illuminate\Http\Request $request
         * @return Response
         */
        public function index(Request $request)
        {
            if($request->ajax()){
                return "AJAX";
            }
            return "HTTP";
        }

basename and dirname solutions are more convenient. Those are alternative commands:

FILE_PATH="/opt/datastores/sda2/test.old.img"
echo "$FILE_PATH" | sed "s/.*\///"

This returns test.old.img like basename.

This is salt filename without extension:

echo "$FILE_PATH" | sed -r "s/.+\/(.+)\..+/\1/"

It returns test.old.

And following statement gives the full path like dirname command.

echo "$FILE_PATH" | sed -r "s/(.+)\/.+/\1/"

It returns /opt/datastores/sda2

Avoid hardcoding try making the code that is dynamic below is the code it will work for any xml I have used SAX Parser you can use dom,xpath it's upto you I am storing all the tags name and values in the map after that it becomes easy to retrieve any values you want I hope this helps
SAMPLE XML:

<parent>
<child >
    <child1> value 1 </child1>
    <child2> value 2 </child2>
    <child3> value 3 </child3>
    </child>
    <child >
     <child4> value 4 </child4>
    <child5> value 5</child5>
    <child6> value 6 </child6>

OK, the first thing to note is that <i> has been deprecated, and shouldn't be used <i> has not been deprecated, but I still do not recommend using it—see the comments for details. This is because it goes entirely against keeping presentation in the presentation layer, which you've pointed out. Similarly, <span class="italic"> seems to break the mold too.

So now we have two real ways of doing things: <em> and <span class="footnote">. Remember that em stands for emphasis. When you wish to apply emphasis to a word, phrase or sentence, stick it in <em> tags regardless of whether you want italics or not. If you want to change the styling in some other way, use CSS: em { font-weight: bold; font-style: normal; }. Of course, you can also apply a class to the <em> tag: if you decide you want certain emphasised phrases to show up in red, give them a class and add it to the CSS:

Fancy some <em class="special">shiny</em> text?

em { font-weight: bold; font-style: normal; }
em.special { color: red; }

If you're applying italics for some other reason, go with the other method and give the section a class. That way, you can change its styling whenever you want without adjusting the HTML. In your example, footnotes should not be emphasised—in fact, they should be de-emphasised, as the point of a footnote is to show unimportant but interesting or useful information. In this case, you're much better off applying a class to the footnote and making it look like one in the presentation layer—the CSS.

The package names in Jackson 2.x got changed to com.fasterxml1 from org.codehaus2. So if you just need ObjectMapper, I think Jackson 1.X can satisfy with your needs.

With C++11, you can do std::string(v.data()) or, if your vector does not contain a '\0' at the end, std::string(v.data(), v.size()).

To turn off line numbering, again follow the preceding instructions, except this time enter the following line at the : prompt:

set nonumber

The error message says that getComputedStyle requires the parameter to be Element type. You receive it because the parameter has an incorrect type.

The most common case is that you try to pass an element that doesn't exist as an argument:

my_element = document.querySelector(#non_existing_id);

Now that element is null, this will result in mentioned error:

my_style = window.getComputedStyle(my_element);

If it's not possible to always get element correctly, you can, for example, use the following to end function if querySelector didn't find any match:

if (my_element === null) return;

From ES6, one can use arrow function syntax as well.

In this example, the code delays keyup event for 400ms after users finish typeing before calling searchFunc make a query request.

const searchbar = document.getElementById('searchBar');
const searchFunc = // any function

// wait ms (milliseconds) after user stops typing to execute func
const delayKeyUp = (() => {
    let timer = null;
    const delay = (func, ms) => {
        timer ? clearTimeout(timer): null
        timer = setTimeout(func, ms)
    }
    return delay
})();

searchbar.addEventListener('keyup', (e) => {
    const query = e.target.value;
    delayKeyUp(() => {searchFunc(query)}, 400);
})

The answer above is now obsolete with Unity 5 or newer. Use this instead!

GetComponent<Rigidbody2D>().AddForce(new Vector2(0,10), ForceMode2D.Impulse);

I also want to add that this leaves the jump height super private and only editable in the script, so this is what I did...

    public float playerSpeed;  //allows us to be able to change speed in Unity
public Vector2 jumpHeight;

// Use this for initialization
void Start () {

}
// Update is called once per frame
void Update ()
{
    transform.Translate(playerSpeed * Time.deltaTime, 0f, 0f);  //makes player run

    if (Input.GetMouseButtonDown(0) || Input.GetKeyDown(KeyCode.Space))  //makes player jump
    {
        GetComponent<Rigidbody2D>().AddForce(jumpHeight, ForceMode2D.Impulse);

This makes it to where you can edit the jump height in Unity itself without having to go back to the script.

Side note - I wanted to comment on the answer above, but I can't because I'm new here. :)

When an iFrame loads, it initially contains the #document, so checking the load state might best work by checking what's there now..

if ($('iframe').contents().find('body').children().length > 0) {
    // is loaded
} else {
    // is not loaded
}

If you are using Photoshop go File > Save for web (Command + Option + Shift + S). Make sure the Transparency is unchecked and this should work.

The answer provided by Zin Min solved my problem with a single line of code. Excellent!

I was having the same issue of converting a generic List to a generic ObservableCollection to use the values from my List to populate a ComboBox that is participating in binding via a factory class for a WPF Window.

_expediteStatuses = new ObservableCollection<ExpediteStatus>(_db.getExpediteStatuses());

Here is the signature for the getExpediteStatuses method:

public List<ExpediteStatus> getExpediteStatuses()

I had the same problem with rails 3.1.0, and I solved adding in file the followings lines:

app/assets/javascripts/application.js
//= require_tree
//= require jquery
//= require jquery_ujs

In addition to the answers already given you probably want to replace all the occurrences. To do this you will need a regular expression as follows :

str = str.replace(/-/g, ' ');  // Replace all '-'  with ' '

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

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

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

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

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

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

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

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

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

To show it only for larger screens, use this:

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

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

Using only css and having no problems with covered and unclickable content before (the point of this is the pointer-events:none):

CSS

.anchored::before {
    content: '';
    display: block;
    position: relative;
    width: 0;
    height: 100px;
    margin-top: -100px;
}

HTML

<a href="#anchor">Click me!</a>
<div style="pointer-events:none;">
<p id="anchor" class="anchored">I should be 100px below where I currently am!</p>
</div>

There's a whole page of the Django documentation devoted to this, well indexed from the contents page.

As that page states, you need to do:

my_obj.categories.add(fragmentCategory.objects.get(id=1))

or

my_obj.categories.create(name='val1')

the simple and easy way to do that is use on event:

$('body').on('click','#element',function(){
    //somthing
});

but we can say this is not the best way to do this. I suggest a another way to do this is use clone() method instead of using dynamic html. Write some html in you file for example:

<div id='div1'></div>

Now in the script tag make a clone of this div then all the properties of this div would follow with new element too. For Example:

var dynamicDiv = jQuery('#div1').clone(true);

Now use the element dynamicDiv wherever you want to add it or change its properties as you like. Now all jQuery functions will work with this element

Its so simple to get logs in React-Native

Use console.log and console.warn

console.log('character', parameter)

console.warn('character', parameter)

This log you can view in browser console. If you want to check device log or say production APK log you can use

adb logcat

adb -d logcat

I solved the problem like this

public static String getUrlParameterValue(String url, String paramName) {
String value = "";
List<NameValuePair> result = null;

try {
    result = URLEncodedUtils.parse(new URI(url), UTF_8);
    value = result.stream().filter(pair -> pair.getName().equals(paramName)).findFirst().get().getValue();
    System.out.println("-------------->  \n" + paramName + " : " + value + "\n");
} catch (URISyntaxException e) {
    e.printStackTrace();
} 
return value;

}

What is the difference between the following ways of handling InterruptedException? What is the best way to do it?

You've probably come to ask this question because you've called a method that throws InterruptedException.

First of all, you should see throws InterruptedException for what it is: A part of the method signature and a possible outcome of calling the method you're calling. So start by embracing the fact that an InterruptedException is a perfectly valid result of the method call.

Now, if the method you're calling throws such exception, what should your method do? You can figure out the answer by thinking about the following:

Does it make sense for the method you are implementing to throw an InterruptedException? Put differently, is an InterruptedException a sensible outcome when calling your method?

• If yes, then throws InterruptedException should be part of your method signature, and you should let the exception propagate (i.e. don't catch it at all).

  Example: Your method waits for a value from the network to finish the computation and return a result. If the blocking network call throws an InterruptedException your method can not finish computation in a normal way. You let the InterruptedException propagate.

  int computeSum(Server server) throws InterruptedException {
      // Any InterruptedException thrown below is propagated
      int a = server.getValueA();
      int b = server.getValueB();
      return a + b;
  }
  

• If no, then you should not declare your method with throws InterruptedException and you should (must!) catch the exception. Now two things are important to keep in mind in this situation:

  1. Someone interrupted your thread. That someone is probably eager to cancel the operation, terminate the program gracefully, or whatever. You should be polite to that someone and return from your method without further ado.

  2. Even though your method can manage to produce a sensible return value in case of an InterruptedException the fact that the thread has been interrupted may still be of importance. In particular, the code that calls your method may be interested in whether an interruption occurred during execution of your method. You should therefore log the fact an interruption took place by setting the interrupted flag: Thread.currentThread().interrupt()

  Example: The user has asked to print a sum of two values. Printing "Failed to compute sum" is acceptable if the sum can't be computed (and much better than letting the program crash with a stack trace due to an InterruptedException). In other words, it does not make sense to declare this method with throws InterruptedException.

  void printSum(Server server) {
       try {
           int sum = computeSum(server);
           System.out.println("Sum: " + sum);
       } catch (InterruptedException e) {
           Thread.currentThread().interrupt();  // set interrupt flag
           System.out.println("Failed to compute sum");
       }
  }
  

By now it should be clear that just doing throw new RuntimeException(e) is a bad idea. It isn't very polite to the caller. You could invent a new runtime exception but the root cause (someone wants the thread to stop execution) might get lost.

Other examples:

Implementing Runnable: As you may have discovered, the signature of Runnable.run does not allow for rethrowing InterruptedExceptions. Well, you signed up on implementing Runnable, which means that you signed up to deal with possible InterruptedExceptions. Either choose a different interface, such as Callable, or follow the second approach above.

Calling Thread.sleep: You're attempting to read a file and the spec says you should try 10 times with 1 second in between. You call Thread.sleep(1000). So, you need to deal with InterruptedException. For a method such as tryToReadFile it makes perfect sense to say, "If I'm interrupted, I can't complete my action of trying to read the file". In other words, it makes perfect sense for the method to throw InterruptedExceptions.

String tryToReadFile(File f) throws InterruptedException {
    for (int i = 0; i < 10; i++) {
        if (f.exists())
            return readFile(f);
        Thread.sleep(1000);
    }
    return null;
}

Way to instantly get first value:

$neededObject = array_reduce(
    $arrayOfObjects,
    function ($result, $item) use ($searchedValue) {
        return $item->id == $searchedValue ? $item : $result;
    }
);

This is a newer answer to this excellent old question. From Hadley's Advanced R:

In a Nutshell

An unwind segue (sometimes called exit segue) can be used to navigate back through push, modal or popover segues (as if you popped the navigation item from the navigation bar, closed the popover or dismissed the modally presented view controller). On top of that you can actually unwind through not only one but a series of push/modal/popover segues, e.g. "go back" multiple steps in your navigation hierarchy with a single unwind action.

When you perform an unwind segue, you need to specify an action, which is an action method of the view controller you want to unwind to.

Objective-C:

- (IBAction)unwindToThisViewController:(UIStoryboardSegue *)unwindSegue
{
}

Swift:

@IBAction func unwindToThisViewController(segue: UIStoryboardSegue) {
}

The name of this action method is used when you create the unwind segue in the storyboard. Furthermore, this method is called just before the unwind segue is performed. You can get the source view controller from the passed UIStoryboardSegue parameter to interact with the view controller that initiated the segue (e.g. to get the property values of a modal view controller). In this respect, the method has a similar function as the prepareForSegue: method of UIViewController.

iOS 8 update: Unwind segues also work with iOS 8's adaptive segues, such as Show and Show Detail.

An Example

Let us have a storyboard with a navigation controller and three child view controllers:

From Green View Controller you can unwind (navigate back) to Red View Controller. From Blue you can unwind to Green or to Red via Green. To enable unwinding you must add the special action methods to Red and Green, e.g. here is the action method in Red:

Objective-C:

@implementation RedViewController

- (IBAction)unwindToRed:(UIStoryboardSegue *)unwindSegue
{
}

@end

Swift:

@IBAction func unwindToRed(segue: UIStoryboardSegue) {
}

After the action method has been added, you can define the unwind segue in the storyboard by control-dragging to the Exit icon. Here we want to unwind to Red from Green when the button is pressed:

You must select the action which is defined in the view controller you want to unwind to:

You can also unwind to Red from Blue (which is "two steps away" in the navigation stack). The key is selecting the correct unwind action.

Before the the unwind segue is performed, the action method is called. In the example I defined an unwind segue to Red from both Green and Blue. We can access the source of the unwind in the action method via the UIStoryboardSegue parameter:

Objective-C:

- (IBAction)unwindToRed:(UIStoryboardSegue *)unwindSegue
{
    UIViewController* sourceViewController = unwindSegue.sourceViewController;

    if ([sourceViewController isKindOfClass:[BlueViewController class]])
    {
        NSLog(@"Coming from BLUE!");
    }
    else if ([sourceViewController isKindOfClass:[GreenViewController class]])
    {
        NSLog(@"Coming from GREEN!");
    }
}

Swift:

@IBAction func unwindToRed(unwindSegue: UIStoryboardSegue) {
    if let blueViewController = unwindSegue.sourceViewController as? BlueViewController {
        println("Coming from BLUE")
    }
    else if let redViewController = unwindSegue.sourceViewController as? RedViewController {
        println("Coming from RED")
    }
}

Unwinding also works through a combination of push/modal segues. E.g. if I added another Yellow view controller with a modal segue, we could unwind from Yellow all the way back to Red in a single step:

Unwinding from Code

When you define an unwind segue by control-dragging something to the Exit symbol of a view controller, a new segue appears in the Document Outline:

Selecting the segue and going to the Attributes Inspector reveals the "Identifier" property. Use this to give a unique identifier to your segue:

After this, the unwind segue can be performed from code just like any other segue:

Objective-C:

[self performSegueWithIdentifier:@"UnwindToRedSegueID" sender:self];

Swift:

performSegueWithIdentifier("UnwindToRedSegueID", sender: self)

Try this:

$("#test-element").on("click" ,function() {
    alert("click");
});

The document way of doing it is weird too. That would make sense to me if used for a class selector, but in the case of an id you probably just have useless DOM traversing there. In the case of the id selector, you get that element instantly.

As nextXXX() methods don't read newline, except nextLine(). We can skip the newline after reading any non-string value (int in this case) by using scanner.skip() as below:

Scanner sc = new Scanner(System.in);
int x = sc.nextInt();
sc.skip("(\r\n|[\n\r\u2028\u2029\u0085])?");
System.out.println(x);
double y = sc.nextDouble();
sc.skip("(\r\n|[\n\r\u2028\u2029\u0085])?");
System.out.println(y);
char z = sc.next().charAt(0);
sc.skip("(\r\n|[\n\r\u2028\u2029\u0085])?");
System.out.println(z);
String hello = sc.nextLine();
System.out.println(hello);
float tt = sc.nextFloat();
sc.skip("(\r\n|[\n\r\u2028\u2029\u0085])?");
System.out.println(tt);

Use an object (key/value pairs, the nearest JavaScript has to an associative array) for this and not the array object. Other than that, I believe that is the most elegant way

var foo = {};
foo['alfa'] = "first item";
foo['beta'] = "second item";

for (var key in foo) {
        console.log(key);
}

Note: JavaScript doesn't guarantee any particular order for the properties. So you cannot expect the property that was defined first to appear first, it might come last.

EDIT:

In response to your comment, I believe that this article best sums up the cases for why arrays in JavaScript should not be used in this fashion -

• "Associative Arrays" considered Harmful

Directly from the GitHub project homepage:

Dapper allow you to pass in IEnumerable and will automatically parameterize your query.

connection.Query<int>(
    @"select * 
      from (select 1 as Id union all select 2 union all select 3) as X 
      where Id in @Ids", 
    new { Ids = new int[] { 1, 2, 3 });

Will be translated to:

select * 
from (select 1 as Id union all select 2 union all select 3) as X 
where Id in (@Ids1, @Ids2, @Ids3)

// @Ids1 = 1 , @Ids2 = 2 , @Ids2 = 3

I had similar issues. I work on a Windows tool chain with a shared repository with Linux guys, and they happily create files with the same (except for case) names in a given folder.

The effect is that I can clone the repository and immediately have dozens of 'modified' files that, if I checked in, would create havoc.

I have Windows set to case sensitive and Git to not ignore case, but it still fails (in the Win32 API calls apparently).

If I gitignore the files then I have to remember to not track the .gitignore file.

But I found a good answer here:

http://archive.robwilkerson.org/2010/03/02/git-tip-ignore-changes-to-tracked-files/index.html

Just put your file.exe in the \bin\Debug folder and use:

Process.Start("File.exe");

one cannot use the Context of the Service; was able to get the (package) Context alike:

Intent intent = new Intent(getApplicationContext(), SomeActivity.class);

http://momentjs.com/docs/#/displaying/unix-timestamp/

You get the number of unix seconds, not milliseconds!

You you need to multiply it with 1000 or using valueOf() and don't forget to use a formatter, since you are using a non ISO 8601 format. And if you forget to pass the formatter, the date will be parsed in the UTC timezone or as an invalid date.

moment("10/15/2014 9:00", "MM/DD/YYYY HH:mm").valueOf()

The recommended way is to use a Mutex. You can check out a sample here : http://www.codeproject.com/KB/cs/singleinstance.aspx

In specific the code:

        /// 
        /// check if given exe alread running or not
        /// 
        /// returns true if already running
        private static bool IsAlreadyRunning()
        {
            string strLoc = Assembly.GetExecutingAssembly().Location;
            FileSystemInfo fileInfo = new FileInfo(strLoc);
            string sExeName = fileInfo.Name;
            bool bCreatedNew;

            Mutex mutex = new Mutex(true, "Global\\"+sExeName, out bCreatedNew);
            if (bCreatedNew)
                mutex.ReleaseMutex();

            return !bCreatedNew;
        }

If you're using jQuery with rails, be wary of allowing entry to methods without verifying the authenticity token.

jquery-ujs can manage the tokens for you

You should have it already as part of the jquery-rails gem, but you might need to include it in application.js with

//= require jquery_ujs

That's all you need - your ajax call should now work

For more information, see: https://github.com/rails/jquery-ujs

case when isdate(inputdate) = 1

As others have said multiprocessing can only transfer Python objects to worker processes which can be pickled. If you cannot reorganize your code as described by unutbu, you can use dills extended pickling/unpickling capabilities for transferring data (especially code data) as I show below.

This solution requires only the installation of dill and no other libraries as pathos:

import os
from multiprocessing import Pool

import dill


def run_dill_encoded(payload):
    fun, args = dill.loads(payload)
    return fun(*args)


def apply_async(pool, fun, args):
    payload = dill.dumps((fun, args))
    return pool.apply_async(run_dill_encoded, (payload,))


if __name__ == "__main__":

    pool = Pool(processes=5)

    # asyn execution of lambda
    jobs = []
    for i in range(10):
        job = apply_async(pool, lambda a, b: (a, b, a * b), (i, i + 1))
        jobs.append(job)

    for job in jobs:
        print job.get()
    print

    # async execution of static method

    class O(object):

        @staticmethod
        def calc():
            return os.getpid()

    jobs = []
    for i in range(10):
        job = apply_async(pool, O.calc, ())
        jobs.append(job)

    for job in jobs:
        print job.get()

Unicode string handling is already standardized in Python 3.

1. char's are already stored in Unicode (32-bit) in memory

2. You only need to open file in utf-8
   (32-bit Unicode to variable-byte-length utf-8 conversion is automatically performed from memory to file.)

   out1 = "(???? ??? ??´ ??` ???` )"
   fobj = open("t1.txt", "w", encoding="utf-8")
   fobj.write(out1)
   fobj.close()
   

Since .NET 4.0 you have System.Tuple<T1, T2> class:

// pair is implicitly typed local variable (method scope)
var pair = System.Tuple.Create("Current century", 21);

Looks very similar to mine but I use the full package name for the receiver:

<receiver android:name=".StartupIntentReceiver">

I have:

<receiver android:name="com.your.package.AutoStart"> 

Unfortunately, the meaning of things like ( and \( are swapped between Emacs style regular expressions and most other styles. So if you try to escape these you may be doing the opposite of what you want.

So you really have to know what style you are trying to quote.

This answer can be a possible solution from many. This answer is for the people who are facing this error while working with File Upload..

We were using middleware for token based encryption - decryption and we encountered same error.

Following was our code in route file:

  router.route("/uploadVideoMessage")
  .post(
    middleware.checkToken,
    upload.single("video_file"),
    videoMessageController.uploadVideoMessage
  );

here we were calling middleware before upload function and that was causing the error. So when we changed it to this, it worked.

router.route("/uploadVideoMessage")
  .post(
    upload.single("video_file"),
    middleware.checkToken,
    videoMessageController.uploadVideoMessage
  );

We cant connect to iPhones normally by bluetooth.it is so difficult.so,please try any other file transfers like zapya,xender.it seems good

A list is immutable by Default, you can use ArrayList instead. like this :

 val orders = arrayListOf<String>()

then you can add/delete items from this like below:

orders.add("Item 1")
orders.add("Item 2")

by default ArrayList is mutable so you can perform the operations on it.

Looks like the inner JSON struct is passed along as a string. You'll have to JSON.parse() it once more to get that data as an object.

try {
  responseData = JSON.parse(responseData);
}
catch (e) {}

Edit: Try the following:

$.ajax({
    type: 'GET',
    dataType: "json",
    url: "http://someotherdomain.com/service.svc",
    success: function (responseData, textStatus, jqXHR) {
        console.log("in");
        var data = JSON.parse(responseData['AuthenticateUserResult']);
        console.log(data);
    },
    error: function (responseData, textStatus, errorThrown) {
        alert('POST failed.');
    }
});

You can look at the following in linux

cd /root

ls -al

vi .mysql_history It may help

The method OfType() will skip the null values:

List<EmailParameterClass> parameterList =
    new List<EmailParameterClass>{param1, param2, param3...};

IList<EmailParameterClass> parameterList_notnull = 
    parameterList.OfType<EmailParameterClass>();

For mobile application i did a solution by injecting javascript in the dialog view. There is a hidden web view in my ios app. That load the fb message send dialog api .. then i inject some javascript to set the "to" and "message" field and submit the form.. So that end user need not to do anything. Message sent to facebook inbox silently...

You need to install a plugin, There is a free one from the eclipse foundation called the Web Tools Platform. It has all the development functionality that you'll need.

You can get the Java EE Edition of eclipse with has it pre-installed.

To create and run your first servlet:

1. New... Project... Dynamic Web Project.
2. Right click the project... New Servlet.
3. Write some code in the doGet() method.
4. Find the servers view in the Java EE perspective, it's usually one of the tabs at the bottom.
5. Right click in there and select new Server.
6. Select Tomcat X.X and a wizard will point you to finding the installation.
7. Right click the server you just created and select Add and Remove... and add your created web project.
8. Right click your servlet and select Run > Run on Server...

That should do it for you. You can use ant to build here if that's what you'd like but eclipse will actually do the build and automatically deploy the changes to the server. With Tomcat you might have to restart it every now and again depending on the change.

By declaring it global inside the function that accesses it:

g_c = 0

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

The Python documentation says this, about the global statement:

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

Make sure that this element you would like to control with z-index does not have a parent with z-index property, because element is in a lower stacking context due to its parent’s z-index level.

Here's an example:

<section class="content">            
    <div class="modal"></div>
</section>

<div class="side-tab"></div>

// CSS //
.content {
    position: relative;
    z-index: 1;
}

.modal {
    position: fixed;
    z-index: 100;
}

.side-tab {
    position: fixed;
    z-index: 5;
}

In the example above, the modal has a higher z-index than the content, although the content will appear on top of the modal because "content" is the parent with a z-index property.

Here's an article that explains 4 reasons why z-index might not work: https://coder-coder.com/z-index-isnt-working/

If you don't see stencils creating new document with a template you may open the template directly. In my case they are located at 'C:\Program Files\Microsoft Office\Office15\Visio Content\1049\' Last foler name varies regarding locale, I guess. UML template is named 'DBUML_M.VSTX'

A lambda expression is like an anonymous method written in place of a delegate instance.

delegate int MyDelagate (int i);
MyDelagate delSquareFunction = x => x * x;

Consider the lambda expression x => x * x;

The input parameter value is x (on the left side of =>)

The function logic is x * x (on the right side of =>)

A lambda expression's code can be a statement block instead of an expression.

x => {return x * x;};

Example

Note: Func is a predefined generic delegate.

    Console.WriteLine(MyMethod(x => "Hi " + x));

    public static string MyMethod(Func<string, string> strategy)
    {
        return strategy("Lijo").ToString();
    }

Take a look on life cycle of Activity

Where

***onCreate()***

Called when the activity is first created. This is where you should do all of your normal static set up: create views, bind data to lists, etc. This method also provides you with a Bundle containing the activity's previously frozen state, if there was one. Always followed by onStart().

***onStart()***

Called when the activity is becoming visible to the user. Followed by onResume() if the activity comes to the foreground, or onStop() if it becomes hidden.

And you can write your simple class to take a look when these methods call

public class TestActivity extends Activity {
    /** Called when the activity is first created. */

    private final static String TAG = "TestActivity";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

Bootstrap 4

It is used to create a bottom margin of 0 (margin-bottom:0). You can see more of the new spacing utility classes here: https://getbootstrap.com/docs/4.0/utilities/spacing/

The best I've seen is Zend Guard.

I know I am late, but what worked for me (total git newbie) was executing the following set of git commands:

git rm -r --cached . 
git add .
git commit -am "Remove ignored files and resubmitting files

To give credit where it is due, here is the link to the source.

With hidden field you need to use like this:

$("._statusDDL").val(2);
$("._statusDDL").change();

or

$("._statusDDL").val(2).change();

linterOptions is currently only handled by the CLI. If you're not using CLI then depending on the code base you're using you'll need to set the ignore somewhere else. webpack, tsconfig, etc

you can do this:

<div class="picture1">&nbsp;</div>

and put this into your css file:

div.picture1 {
   width:100px; /*width of your image*/
   height:100px; /*height of your image*/
   background-image:url('yourimage.file');
   margin:0; /* If you want no margin */
   padding:0; /*if your want to padding */
}

otherwise, just use them as plain

You could use the RedirectMatch directive in Apache to do something similar you want.

It's pretty simple.

RedirectMatch / http://222.222.222.222/

Anyway, I can't see any reason to do that thing. Aren't you trying to intercept traffic? There are better ways. For Linux boxes as a router: iptables -j REDIRECT + Squid or Apache. For Cisco routers, you can use WCCP to a Cache or Web Server...

colrm x

For example, if you need the first 100 characters:

cat file |colrm 101 

It's been around for years and is in most linux's and bsd's (freebsd for sure), usually by default. I can't remember ever having to type apt-get install colrm.

The official language specification for XPath 2.0 on W3.org details that the language does indeed support if statements. See Section 3.8 Conditional Expressions, in particular. Along with the syntax format and explanation, it gives the following example:

if ($widget1/unit-cost < $widget2/unit-cost) 
  then $widget1
  else $widget2

This would suggest that you shouldn't have brackets surrounding your expressions (otherwise the syntax looks correct). I'm not wholly confident, but it's surely worth a try. So you'll want to change your query to look like this:

if (fn:ends-with(//div [@id='head']/text(),': '))
  then fn:substring-before(//div [@id='head']/text(),': ')
  else //div [@id='head']/text()

I do strongly suspect this may fix it however, as the fact that your XPath engine seems to be trying to interpret if as a function, where it is in fact a special construct of the language.

Finally, to point out the obvious, insure that your XPath engine does in fact support XPath 2.0 (as opposed to an earlier version)! I don't believe conditional expressions are part of previous versions of XPath.

LIKE does matching like wildcards char [*, ?] at the shell

Depends on the case actually.

Hooking in programming is a technique employing so-called hooks to make a chain of procedures as an event handler.

It's not the angular way, remove the function from html body and use it in controller, or use

angular.element(document).ready

In Layout .xml file

<Button
 android:id="@+id/button1"
 android:background="@drawable/btn_selector"
 android:layout_width="100dp"
 android:layout_height="50dp"
 android:text="press" />

btn_selector.xml

<?xml version="1.0" encoding="utf-8"?>

 <item android:drawable="@drawable/btn_bg_selected" android:state_selected="true"></item>
<item android:drawable="@drawable/btn_bg_pressed" android:state_pressed="true"></item>
<item android:drawable="@drawable/btn_bg_normal"></item>

There is an easier way than the one written by CommonsWare. Just create a drawable resource that specifies the way the EditText will be drawn:

<?xml version="1.0" encoding="utf-8"?>
<!--  res/drawable/rounded_edittext.xml -->
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" 
    android:padding="10dp">

    <solid android:color="#FFFFFF" />
    <corners
        android:bottomRightRadius="15dp"
        android:bottomLeftRadius="15dp"
        android:topLeftRadius="15dp"
        android:topRightRadius="15dp" />
</shape>

Then, just reference this drawable in your layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <EditText  
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:padding="5dip"
        android:background="@drawable/rounded_edittext" />
</LinearLayout>

You will get something like:

Edit

Based on Mark's comment, I want to add the way you can create different states for your EditText:

<?xml version="1.0" encoding="utf-8"?>
<!-- res/drawable/rounded_edittext_states.xml -->
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item 
        android:state_pressed="true" 
        android:state_enabled="true"
        android:drawable="@drawable/rounded_focused" />
    <item 
        android:state_focused="true" 
        android:state_enabled="true"
        android:drawable="@drawable/rounded_focused" />
    <item 
        android:state_enabled="true"
        android:drawable="@drawable/rounded_edittext" />
</selector>

These are the states:

<?xml version="1.0" encoding="utf-8"?>
<!-- res/drawable/rounded_edittext_focused.xml -->
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" android:padding="10dp">

    <solid android:color="#FFFFFF"/>
    <stroke android:width="2dp" android:color="#FF0000" />
    <corners
        android:bottomRightRadius="15dp"
        android:bottomLeftRadius="15dp"
        android:topLeftRadius="15dp"
        android:topRightRadius="15dp" />
</shape>

And... now, the EditText should look like:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <EditText  
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:text="@string/hello"
        android:background="@drawable/rounded_edittext_states"
        android:padding="5dip" />
</LinearLayout>

you must check if you implemented the page in the controller for example:

   public ActionResult Register()
        {
            return View();
        } 

what this means ? is there any problem in my code

It means that you are accessing a location or index which is not present in collection.

To find this, Make sure your Gridview has 5 columns as you are using it's 5th column by this line

dataGridView1.Columns[4].Name = "Amount";

Here is the image which shows the elements of an array. So if your gridview has less column then the (index + 1) by which you are accessing it, then this exception arises.

Your issue is, that you have an apache webserver already running that is already using port 80. So, you can either:

1. Kill apache: You should probably do this via /etc/init.d/apache2 stop, rather than simply killing them.

2. Deploy your flask app in your apache process, as flask in apache describes.

The following groovy script would be useful, if your job does not use "Source Code Management" directly (likewise "Git Parameter Plugin"), but still have access to a local (cloned) git repository:

import jenkins.model.Jenkins

def envVars = Jenkins.instance.getNodeProperties()[0].getEnvVars() 
def GIT_PROJECT_PATH = envVars.get('GIT_PROJECT_PATH') 
def gettags = "git ls-remote -t --heads origin".execute(null, new File(GIT_PROJECT_PATH))

return gettags.text.readLines()
         .collect { it.split()[1].replaceAll('\\^\\{\\}', '').replaceAll('refs/\\w+/', '')  }
         .unique()

I wanted to do the same thing as, but I wanted to do it in the one file.

So the logic would be:

• if a script with my name is running, kill it, then exit
• if a script with my name is not running, do stuff

I modified the answer by Bakuriu and came up with this:

from os import getpid
from sys import argv, exit
import psutil  ## pip install psutil

myname = argv[0]
mypid = getpid()
for process in psutil.process_iter():
    if process.pid != mypid:
        for path in process.cmdline():
            if myname in path:
                print "process found"
                process.terminate()
                exit()

## your program starts here...

Running the script will do whatever the script does. Running another instance of the script will kill any existing instance of the script.

I use this to display a little PyGTK calendar widget which runs when I click the clock. If I click and the calendar is not up, the calendar displays. If the calendar is running and I click the clock, the calendar disappears.

hmm, well here's a workaround anyway:

function JSON_stringify(s, emit_unicode)
{
   var json = JSON.stringify(s);
   return emit_unicode ? json : json.replace(/[\u007f-\uffff]/g,
      function(c) { 
        return '\\u'+('0000'+c.charCodeAt(0).toString(16)).slice(-4);
      }
   );
}

test case:

js>s='15\u00f8C 3\u0111';
15°C 3?
js>JSON_stringify(s, true)
"15°C 3?"
js>JSON_stringify(s, false)
"15\u00f8C 3\u0111"

Java has no map literal, so there's no nice way to do exactly what you're asking.

If you need that type of syntax, consider some Groovy, which is Java-compatible and lets you do:

def map = [name:"Gromit", likes:"cheese", id:1234]

I have not run into this problem personally, but try checking the following settings (File -> Settings or Alt+F7):

Project Settings [name]
Inspections - ensure that Android and Android Lint is checked, or alternately just set it back to default using the dropdown box at the top.

IDE Settings
Editor -> Code Completion - ensure the Autopopup code completion is checked (and check the rest of the settings based on your preference.

It's O(V+E) because each visit to v of V must visit each e of E where |e| <= V-1. Since there are V visits to v of V then that is O(V). Now you have to add V * |e| = E => O(E). So total time complexity is O(V + E).

The Abandon method should work (MSDN):

Session.Abandon();

If you want to remove a specific item from the session use (MSDN):

Session.Remove("YourItem");

EDIT: If you just want to clear a value you can do:

Session["YourItem"] = null;

If you want to clear all keys do:

Session.Clear();

If none of these are working for you then something fishy is going on. I would check to see where you are assigning the value and verify that it is not getting reassigned after you clear the value.

Simple check do:

Session["YourKey"] = "Test";  // creates the key
Session.Remove("YourKey");    // removes the key
bool gone = (Session["YourKey"] == null);   // tests that the remove worked

You can use find_all in the following way to find every a element that has an href attribute, and print each one:

from BeautifulSoup import BeautifulSoup

html = '''<a href="some_url">next</a>
<span class="class"><a href="another_url">later</a></span>'''

soup = BeautifulSoup(html)

for a in soup.find_all('a', href=True):
    print "Found the URL:", a['href']

The output would be:

Found the URL: some_url
Found the URL: another_url

Note that if you're using an older version of BeautifulSoup (before version 4) the name of this method is findAll. In version 4, BeautifulSoup's method names were changed to be PEP 8 compliant, so you should use find_all instead.

If you want all tags with an href, you can omit the name parameter:

href_tags = soup.find_all(href=True)

<head>
<meta http-equiv='X-UA-Compatible' content='IE=edge'>

worked for me, to force IE to "snap out of compatibility mode" (so to speak), BUT that meta statement must appear IMMEDIATELY after the <head>, or it won't work!

When you want to show years and the remaining days:

var m = moment(d.birthday.date, "DD.MM.YYYY");
var years = moment().diff(m, 'years', false);
var days = moment().diff(m.add(years, 'years'), 'days', false);
alert(years + ' years, ' + days + ' days');

mkdir does not support -p switch anymore on Windows 8+ systems.

You can use this:

IF NOT EXIST dir_name MKDIR dir_name

To store the third line into a variable, use below syntax:

variable=`echo "$1" | sed '3q;d' urfile`

To store the changed line into a variable, use below syntax: variable=echo 'overflow' | sed -e "s/over/"OVER"/g" output:OVERflow

No need to create a GD resource, as someone else suggested.

$input = 'http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com';
$output = 'google.com.jpg';
file_put_contents($output, file_get_contents($input));

Note: this solution only works if you're setup to allow fopen access to URLs. If the solution above doesn't work, you'll have to use cURL.

Generics only support object types, not primitives. Unlike C++ templates, generics don't involve code generatation and there is only one HashMap code regardless of the number of generic types of it you use.

Trove4J gets around this by pre-generating selected collections to use primitives and supports TCharIntHashMap which to can wrap to support the Map<Character, Integer> if you need to.

I once needed to upload PDFs to an online backup archive. But the backup would fail if the user had the file open in another program (such as PDF reader). In my haste, I attempted a few of the top answers in this thread but could not get them to work. What did work for me was trying to move the PDF file to its own directory. I found that this would fail if the file was open in another program, and if the move were successful there would be no restore-operation required as there would be if it were moved to a separate directory. I want to post my basic solution in case it may be useful for others' specific use cases.

string str_path_and_name = str_path + '\\' + str_filename;
FileInfo fInfo = new FileInfo(str_path_and_name);
bool open_elsewhere = false;
try
{
    fInfo.MoveTo(str_path_and_name);
}
catch (Exception ex)
{
    open_elsewhere = true;
}

if (open_elsewhere)
{
    //handle case
}

while test the condition before executing statements in the while loop.

do while test the condition after having executed statement inside the loop.

Timezone/daylight savings aware date increment for JavaScript dates:

function nextDay(date) {
    const sign = v => (v < 0 ? -1 : +1);
    const result = new Date(date.getTime());
    result.setDate(result.getDate() + 1);
    const offset = result.getTimezoneOffset();
    return new Date(result.getTime() + sign(offset) * offset * 60 * 1000);
}

My solution breaks down in 3 parts: the state of the user is stored in a service, in the run method you watch when the route changes and you check if the user is allowed to access the requested page, in your main controller you watch if the state of the user change.

app.run(['$rootScope', '$location', 'Auth', function ($rootScope, $location, Auth) {
    $rootScope.$on('$routeChangeStart', function (event) {

        if (!Auth.isLoggedIn()) {
            console.log('DENY');
            event.preventDefault();
            $location.path('/login');
        }
        else {
            console.log('ALLOW');
            $location.path('/home');
        }
    });
}]);

You should create a service (I will name it Auth) which will handle the user object and have a method to know if the user is logged or not.

service:

 .factory('Auth', function(){
var user;

return{
    setUser : function(aUser){
        user = aUser;
    },
    isLoggedIn : function(){
        return(user)? user : false;
    }
  }
})

From your app.run, you should listen the $routeChangeStart event. When the route will change, it will check if the user is logged (the isLoggedIn method should handle it). It won't load the requested route if the user is not logged and it will redirect the user to the right page (in your case login).

The loginController should be used in your login page to handle login. It should just interract with the Auth service and set the user as logged or not.

loginController:

.controller('loginCtrl', [ '$scope', 'Auth', function ($scope, Auth) {
  //submit
  $scope.login = function () {
    // Ask to the server, do your job and THEN set the user

    Auth.setUser(user); //Update the state of the user in the app
  };
}])

From your main controller, you could listen if the user state change and react with a redirection.

.controller('mainCtrl', ['$scope', 'Auth', '$location', function ($scope, Auth, $location) {

  $scope.$watch(Auth.isLoggedIn, function (value, oldValue) {

    if(!value && oldValue) {
      console.log("Disconnect");
      $location.path('/login');
    }

    if(value) {
      console.log("Connect");
      //Do something when the user is connected
    }

  }, true);

Emoji support for application having tech stack - mysql, java, springboot, hibernate

Apply below changes in mysql for unicode support.

1. ALTER DATABASE <database-name> CHARACTER SET = utf8mb4 COLLATE = utf8mb4_unicode_ci;
2. ALTER TABLE <table-name> CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

DB Connection - jdbc url change:

jdbc:mysql://localhost:3306/<database-name>?useUnicode=yes&characterEncoding=UTF-8

Note - If the above step is not working please update mysql-connector version to 8.0.15. (mysql 5.7 works with connector version 8.0.15 for unicode support)

If the variable is declared (either with the var keyword, as a function argument, or as a global variable), I think the best way to do it is:

if (my_variable === undefined)

jQuery does it, so it's good enough for me :-)

Otherwise, you'll have to use typeof to avoid a ReferenceError.

If you expect undefined to be redefined, you could wrap your code like this:

(function(undefined){
    // undefined is now what it's supposed to be
})();

Or obtain it via the void operator:

const undefined = void 0;
// also safe

this is a way for emulate addEventListener or attachEvent on browsers that don't support one of those
hope will help

(function (w,d) {  //

        a   = "addEventListener",
        n   = a in w,
        c   = (nc = "Event")+(n?(nc+= "", "Listener") : (nc+="Listener","") ),
        u   = n?(nu = "attach", "add"):(nu = "add","attach"),
        r   = n?(nr = "detach","remove"):(nr = "remove","detach")
/*
 * the evtf function, when invoked, return "attach" or "detach" "Event" functions if we are on a new browser, otherwise add "add" or "remove" "EventListener"
 */
    function evtf(whoe){return function(evnt,func,capt){return this[whoe]((n?((t = evnt.split("on"))[1] || t[0]) : ("on"+evnt)),func, (!n && capt? (whoe.indexOf("detach") < 0 ? this.setCapture() : this.removeCapture() ) : capt  ))}}
    w[nu + nc] = Element.prototype[nu + nc] = document[nu + nc] = evtf(u+c) // (add | attach)Event[Listener]
    w[nr + nc] = Element.prototype[nr + nc] = document[nr + nc] = evtf(r+c) // (remove | detach)Event[Listener]

})(window, document)

Many of the other solutions offered this thread are not doing this correctly.

• Splitting on \r\n\r\n is not reliable when CURLOPT_FOLLOWLOCATION is on or when the server responds with a 100 code.
• Not all servers are standards compliant and transmit just a \n for new lines.
• Detecting the size of the headers via CURLINFO_HEADER_SIZE is also not always reliable, especially when proxies are used or in some of the same redirection scenarios.

The most correct method is using CURLOPT_HEADERFUNCTION.

Here is a very clean method of performing this using PHP closures. It also converts all headers to lowercase for consistent handling across servers and HTTP versions.

This version will retain duplicated headers

This complies with RFC822 and RFC2616, please do not suggest edits to make use of the mb_ string functions, it is incorrect!

$ch = curl_init();
$headers = [];
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

// this function is called by curl for each header received
curl_setopt($ch, CURLOPT_HEADERFUNCTION,
  function($curl, $header) use (&$headers)
  {
    $len = strlen($header);
    $header = explode(':', $header, 2);
    if (count($header) < 2) // ignore invalid headers
      return $len;

    $headers[strtolower(trim($header[0]))][] = trim($header[1]);

    return $len;
  }
);

$data = curl_exec($ch);
print_r($headers);

For arbitrary precision mathematics PHP offers the Binary Calculator which supports numbers of any size and precision, represented as strings.

$s = '1234.13';
$double = bcadd($s,'0',2);

To answer the original posters question.... to 'decrypt' the password, you have to do what a password cracker would do.

In other words, you'd run a program to read from a large list of potential passwords (a password dictionary) and you'd hash each one using bcrypt and the salt and complexity from the password you're trying to decipher. If you're lucky you'll find a match, but if the password is a strong one then you likely won't find a match.

Bcrypt has the added security characteristic of being a slow hash. If your password had been hashed with md5 (terrible choice) then you'd be able to check billions of passwords per second, but since it's hashed using bcrypt you will be able to check far fewer per second.

The fact that bcrypt is slow to hash and salted is what makes it a good choice for password storage even today. That being said I believe NIST recommends the PBKDF2 for password hashing.

You simply need to remove v-bind (:) from selected and required attributes. Like this :-

<template>_x000D_
    <select class="form-control" v-model="selected" required @change="changeLocation">_x000D_
        <option selected>Choose Province</option>_x000D_
        <option v-for="option in options" v-bind:value="option.id" >{{ option.name }}</option>_x000D_
    </select>_x000D_
</template>

You are not binding anything to the vue instance through these attributes thats why it is giving error.

Here's a quick two-liner that I use to quickly create a file if it doesn't exists.

if not os.path.exists(filename):
    open(filename, 'w').close()

There are lots of answers here but unfortunately all of them are quite old and therefore rely on attr/removeAttr which is really not the way to go.

@coffeeyesplease correctly mentions that a good, cross-browser solution is to use

$("select").val([]);

Another good cross-browser solution is

// Note the use of .prop instead of .attr
$("select option").prop("selected", false);

You can see it run a self-test here. Tested on IE 7/8/9, FF 11, Chrome 19.

When you are dumping all database. Obviously it is having large data. So you can prefer below for better:

Creating Backup:

mysqldump -u [user] -p[password]--single-transaction --quick --all-databases | gzip > alldb.sql.gz

If error

-- Warning: Skipping the data of table mysql.event. Specify the --events option explicitly.

Use:

mysqldump -u [user] -p --events --single-transaction --quick --all-databases | gzip > alldb.sql.gz

Restoring Backup:

gunzip < alldb.sql.gz | mysql -u [user] -p[password]

Hope it will help :)

Sometimes you might add a state value from props in constructor or componentDidMount, you might need to call setState when the props changed but the component has already mounted so componentDidMount will not execute and neither will constructor; in this particular case, you can use componentDidUpdate since the props have changed, you can call setState in componentDidUpdate with new props.

prop.table is a nice friendly way of obtaining proportions of tables.

m <- matrix(1:4,2)

 m
     [,1] [,2]
[1,]    1    3
[2,]    2    4

Leaving margin blank gives you proportions of the whole table

 prop.table(m, margin=NULL)
     [,1] [,2]
[1,]  0.1  0.3
[2,]  0.2  0.4

Giving it 1 gives you row proportions

 prop.table(m, 1)
      [,1]      [,2]
[1,] 0.2500000 0.7500000
[2,] 0.3333333 0.6666667

And 2 is column proportions

 prop.table(m, 2)
          [,1]      [,2]
[1,] 0.3333333 0.4285714
[2,] 0.6666667 0.5714286

I think this would do it...

def validIP(address):
    parts = address.split(".")
    if len(parts) != 4:
        return False
    for item in parts:
        if not 0 <= int(item) <= 255:
            return False
    return True

From my experience event.stopPropagation() is mostly used in CSS effect or animation works, for instance when you have hover effect for both card and button element, when you hover on the button both card and buttons hover effect will be triggered in this case, you can use event.stopPropagation() stop bubbling actions, and event.preventDefault() is for prevent default behaviour of browser actions. For instance, you have form but you only defined click event for the submit action, if the user submits the form by pressing enter, the browser triggered by keypress event, not your click event here you should use event.preventDefault() to avoid inappropriate behavior. I don't know what the hell is return false; sorry.For more clarification visit this link and play around with line #33 https://www.codecademy.com/courses/introduction-to-javascript/lessons/requests-i/exercises/xhr-get-request-iv

There is no "second property" -- when you say var obj = { ... }, the properties inside the braces are unordered. Even a 'for' loop walking through them might return them in different orders on different JavaScript implementations.

this is old but for help :

you can also use the stringReader stream

string str = "asasdkopaksdpoadks";
StringReader TheStream = new StringReader( str );

Unfortunately, C++ does not allow you to directly get a callable object referring to an object and one of its member functions. &Foo::doSomething gives you a "pointer to member function" which refers to the member function but not the associated object.

There are two ways around this, one is to use std::bind to bind the "pointer to member function" to the this pointer. The other is to use a lambda that captures the this pointer and calls the member function.

std::function<void(void)> f = std::bind(&Foo::doSomething, this);
std::function<void(void)> g = [this](){doSomething();};

I would prefer the latter.

With g++ at least binding a member function to this will result in an object three-pointers in size, assigning this to an std::function will result in dynamic memory allocation.

On the other hand, a lambda that captures this is only one pointer in size, assigning it to an std::function will not result in dynamic memory allocation with g++.

While I have not verified this with other compilers, I suspect similar results will be found there.

For starters ignore all answers with tell you to use $watch. Angular works off of a listener already. I guarantee you that you are complicating things by merely thinking in this direction.

Ignore all answers that tell you to user $timeout. You cannot know how long the page will take to load, therefore this is not the best solution.

You only need to know when the page is done rendering.

<div ng-app='myApp'>
<div ng-controller="testctrl">
    <label>{{total}}</label>
    <table>
      <tr ng-repeat="item in items track by $index;" ng-init="end($index);">
        <td>{{item.number}}</td>
      </tr>
    </table>
</div>

var app = angular.module('myApp', ["testctrl"]);
var controllers = angular.module("testctrl", []);
 controllers.controller("testctrl", function($scope) {

  $scope.items = [{"number":"one"},{"number":"two"},{"number":"three"}];

  $scope.end = function(index){
  if(index == $scope.items.length -1
        && typeof $scope.endThis == 'undefined'){

            ///  DO STUFF HERE
      $scope.total = index + 1;
      $scop.endThis  = true;
 }
}
});

Track the ng-repeat by $index and when the length of array equals the index stop the loop and do your logic.

rbind(x, 1:10)
cbind(x, 1:10)
c(x, 10)

With eager evaluation, variables essentially turn into their values any time you look at them (to paraphrase). That said, Python does have built-in namespaces. For example, locals() will return a dictionary mapping a function's variables' names to their values, and globals() does the same for a module. Thus:

for name, value in globals().items():
    if value is unknown_variable:
        ... do something with name

Note that you don't need to import anything to be able to access locals() and globals().

Also, if there are multiple aliases for a value, iterating through a namespace only finds the first one.

As an addition to this previous answer, pipes can be used inside a for statement, escaped by a caret symbol:

    for /f "tokens=*" %%i in ('tasklist ^| grep "explorer"') do set VAR=%%i

Building on Brian's answer, the upload-pack path can be set permanently by running the following commands after cloning, which eliminates the need for --upload-pack on subsequent pull/fetch requests. Similarly, setting receive-pack eliminates the need for --receive-pack on push requests.

git config remote.origin.uploadpack /path/to/git-upload-pack
git config remote.origin.receivepack /path/to/git-receive-pack

These two commands are equivalent to adding the following lines to a repo's .git/config.

[remote "origin"]
    uploadpack = /path/to/git-upload-pack
    receivepack = /path/to/git-receive-pack

Frequent users of clone -u may be interested in the following aliases. myclone should be self-explanatory. myfetch/mypull/mypush can be used on repos whose config hasn't been modified as described above by replacing git push with git mypush, and so on.

[alias]
    myclone = clone --upload-pack /path/to/git-upload-pack
    myfetch = fetch --upload-pack /path/to/git-upload-pack
    mypull  = pull --upload-pack /path/to/git-upload-pack
    mypush  = push --receive-pack /path/to/git-receive-pack

This should do

import pylab as plot
params = {'legend.fontsize': 20,
          'legend.handlelength': 2}
plot.rcParams.update(params)

Then do the plot afterwards.

There are a ton of other rcParams, they can also be set in the matplotlibrc file.

Also presumably you can change it passing a matplotlib.font_manager.FontProperties instance but this I don't know how to do. --> see Yann's answer.

You could put a _ViewStart.cshtml file inside the /Views/Public folder which would override the default one in the /Views folder and specify the desired layout:

@{
    Layout = "~/Views/Shared/_PublicLayout.cshtml";
}

By analogy you could put another _ViewStart.cshtml file inside the /Views/Staff folder with:

@{
    Layout = "~/Views/Shared/_StaffLayout.cshtml";
}

You could also specify which layout should be used when returning a view inside a controller action but that's per action:

return View("Index", "~/Views/Shared/_StaffLayout.cshtml", someViewModel);

Yet another possibility is a custom action filter which would override the layout. As you can see many possibilities to achieve this. Up to you to choose which one fits best in your scenario.

UPDATE:

As requested in the comments section here's an example of an action filter which would choose a master page:

public class LayoutInjecterAttribute : ActionFilterAttribute
{
    private readonly string _masterName;
    public LayoutInjecterAttribute(string masterName)
    {
        _masterName = masterName;
    }

    public override void OnActionExecuted(ActionExecutedContext filterContext)
    {
        base.OnActionExecuted(filterContext);
        var result = filterContext.Result as ViewResult;
        if (result != null)
        {
            result.MasterName = _masterName;
        }
    }
}

and then decorate a controller or an action with this custom attribute specifying the layout you want:

[LayoutInjecter("_PublicLayout")]
public ActionResult Index()
{
    return View();
}

Restarting Your Server Can Resolve this problem.

I was getting the same error while Using Dynamic Jasper Reporting , When i deploy my Application for first use to Create Reports, the Report creation works fine, But Once I Do Hot Deployment of some code changes To the Server, I was getting This Error.

If you really want to use linq, you can do something like this

li= (from tl in li
    select new Myclass
    {
        name = tl.name,
        age = (tl.name == "di" ? 10 : (tl.name == "marks" ? 20 : 30))

    }).ToList();

or

li = li.Select(ex => new MyClass { name = ex.name, age = (ex.name == "di" ? 10 : (ex.name == "marks" ? 20 : 30)) }).ToList();

This assumes that there are only 3 types of name. I would externalize that part into a function to make it more manageable.

There are two ways to approach this problem: numerically and symbolically.

To solve it numerically, you have to first encode it as a "runnable" function - stick a value in, get a value out. For example,

def my_function(x):
    return 2*x + 6

It is quite possible to parse a string to automatically create such a function; say you parse 2x + 6 into a list, [6, 2] (where the list index corresponds to the power of x - so 6*x^0 + 2*x^1). Then:

def makePoly(arr):
    def fn(x):
        return sum(c*x**p for p,c in enumerate(arr))
    return fn

my_func = makePoly([6, 2])
my_func(3)    # returns 12

You then need another function which repeatedly plugs an x-value into your function, looks at the difference between the result and what it wants to find, and tweaks its x-value to (hopefully) minimize the difference.

def dx(fn, x, delta=0.001):
    return (fn(x+delta) - fn(x))/delta

def solve(fn, value, x=0.5, maxtries=1000, maxerr=0.00001):
    for tries in xrange(maxtries):
        err = fn(x) - value
        if abs(err) < maxerr:
            return x
        slope = dx(fn, x)
        x -= err/slope
    raise ValueError('no solution found')

There are lots of potential problems here - finding a good starting x-value, assuming that the function actually has a solution (ie there are no real-valued answers to x^2 + 2 = 0), hitting the limits of computational accuracy, etc. But in this case, the error minimization function is suitable and we get a good result:

solve(my_func, 16)    # returns (x =) 5.000000000000496

Note that this solution is not absolutely, exactly correct. If you need it to be perfect, or if you want to try solving families of equations analytically, you have to turn to a more complicated beast: a symbolic solver.

A symbolic solver, like Mathematica or Maple, is an expert system with a lot of built-in rules ("knowledge") about algebra, calculus, etc; it "knows" that the derivative of sin is cos, that the derivative of kx^p is kpx^(p-1), and so on. When you give it an equation, it tries to find a path, a set of rule-applications, from where it is (the equation) to where you want to be (the simplest possible form of the equation, which is hopefully the solution).

Your example equation is quite simple; a symbolic solution might look like:

=> LHS([6, 2]) RHS([16])

# rule: pull all coefficients into LHS
LHS, RHS = [lh-rh for lh,rh in izip_longest(LHS, RHS, 0)], [0]

=> LHS([-10,2]) RHS([0])

# rule: solve first-degree poly
if RHS==[0] and len(LHS)==2:
    LHS, RHS = [0,1], [-LHS[0]/LHS[1]]

=> LHS([0,1]) RHS([5])

and there is your solution: x = 5.

I hope this gives the flavor of the idea; the details of implementation (finding a good, complete set of rules and deciding when each rule should be applied) can easily consume many man-years of effort.

In case you don't want to set fixed width to anything

The solution below allows you to have table cell content that is long, but must not affect the width of the parent table, nor the height of the parent row. For example where you want to have a table with width:100% that still applies auto-size feature to all other cells. Useful in data grids with "Notes" or "Comment" column or something.

Add these 3 rules to your CSS:

.text-overflow-dynamic-container {
    position: relative;
    max-width: 100%;
    padding: 0 !important;
    display: -webkit-flex;
    display: -moz-flex;
    display: flex;
    vertical-align: text-bottom !important;
}
.text-overflow-dynamic-ellipsis {
    position: absolute;
    white-space: nowrap;
    overflow-y: visible;
    overflow-x: hidden;
    text-overflow: ellipsis;
    -ms-text-overflow: ellipsis;
    -o-text-overflow: ellipsis;
    max-width: 100%;
    min-width: 0;
    width:100%;
    top: 0;
    left: 0;
}
.text-overflow-dynamic-container:after,
.text-overflow-dynamic-ellipsis:after {
    content: '-';
    display: inline;
    visibility: hidden;
    width: 0;
}

Format HTML like this in any table cell you want dynamic text overflow:

<td>
  <span class="text-overflow-dynamic-container">
    <span class="text-overflow-dynamic-ellipsis" title="...your text again for usability...">
      //...your long text here...
    </span>
  </span>
</td>

Additionally apply desired min-width (or none at all) to the table cell.

jQuery uses a regex to remove script tags in some cases and I'm pretty sure its devs had a damn good reason to do so. Probably some browser does execute scripts when inserting them using innerHTML.

Here's the regex:

/<script\b[^<]*(?:(?!<\/script>)<[^<]*)*<\/script>/gi

And before people start crying "but regexes for HTML are evil": Yes, they are - but for script tags they are safe because of the special behaviour - a <script> section may not contain </script> at all unless it should end at this position. So matching it with a regex is easily possible. However, from a quick look the regex above does not account for trailing whitespace inside the closing tag so you'd have to test if </script    etc. will still work.

Try this using a previously mentioned regex:

String regex = "^([A-Za-z0-9+/]{4})*([A-Za-z0-9+/]{4}|[A-Za-z0-9+/]{3}=|[A-Za-z0-9+/]{2}==)$";
if("TXkgdGVzdCBzdHJpbmc/".matches(regex)){
    System.out.println("it's a Base64");
}

...We can also make a simple validation like, if it has spaces it cannot be Base64:

String myString = "Hello World";
 if(myString.contains(" ")){
   System.out.println("Not B64");
 }else{
    System.out.println("Could be B64 encoded, since it has no spaces");
 }

An improved solution with filtering possibilities. This result is more convenient as you can refer any object property directly with array paths like:

["aProperty.aSetting1", "aProperty.aSetting2", "aProperty.aSetting3", "aProperty.aSetting4", "aProperty.aSetting5", "bProperty.bSetting1.bPropertySubSetting", "bProperty.bSetting2", "cProperty.cSetting"]

 /**
 * Recursively searches for properties in a given object. 
 * Ignores possible prototype endless enclosures. 
 * Can list either all properties or filtered by key name.
 *
 * @param {Object} object Object with properties.
 * @param {String} key Property key name to search for. Empty string to 
 *                     get all properties list .
 * @returns {String} Paths to properties from object root.
 */
function getPropertiesByKey(object, key) {

  var paths = [
  ];

  iterate(
    object,
    "");

  return paths;

  /**
   * Single object iteration. Accumulates to an outer 'paths' array.
   */
  function iterate(object, path) {
    var chainedPath;

    for (var property in object) {
      if (object.hasOwnProperty(property)) {

        chainedPath =
          path.length > 0 ?
          path + "." + property :
          path + property;

        if (typeof object[property] == "object") {

          iterate(
            object[property],
            chainedPath,
            chainedPath);
        } else if (
          property === key ||
          key.length === 0) {

          paths.push(
            chainedPath);
        }
      }
    }

    return paths;
  }
}

added good images with explain scopes

Make your object something like

public class MyObject : IComparable
{
    public string a;
    public string b;

    virtual public int CompareTo(object obj)
    {
        if (obj is MyObject)
        {
            var compareObj = (MyObject)obj;
            if (this.a.CompareTo(compareObj.a) == 0)
            {
                // compare second value
                return this.b.CompareTo(compareObj.b);
            }
            return this.a.CompareTo(compareObj.b);
        }
        else
        {
            throw new ArgumentException("Object is not a MyObject ");
        }
    }
}

also note that the returns for CompareTo :

http://msdn.microsoft.com/en-us/library/system.icomparable.compareto.aspx

Then, if you have a List of MyObject, call .Sort() ie

var objList = new List<MyObject>();
objList.Sort();

// using System.Xml;

String rawXml =
      @"<root>
          <person firstname=""Riley"" lastname=""Scott"" />
          <person firstname=""Thomas"" lastname=""Scott"" />
      </root>";

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(rawXml);

I think this should work.

<img id="output_image" height=50px width=50px\
<input type="file" accept="image/*" onchange="preview_image(event)">

<script type"text/javascript">
  function preview_image(event) {
    var reader = new FileReader();
    reader.onload = function(){
      var output = document.getElementById('output_image');
      output.src = reader.result;
    }
    reader.readAsDataURL(event.target.files[0]);
  }
</script>

You can enable and disable button or by using condition or directly by default it will be disable : true

 // in calling function of button 
    handledisableenable()
        {
         // set the state for disabling or enabling the button
           if(ifSomeConditionReturnsTrue)
            {
                this.setState({ Isbuttonenable : true })
            }
          else
          {
             this.setState({ Isbuttonenable : false})
          }
        }

<TouchableOpacity onPress ={this.handledisableenable} disabled= 
     {this.state.Isbuttonenable}>

    <Text> Button </Text>
</TouchableOpacity>

I was getting this error, even though I have exported RouterModule from app-routing.module and imported app-routingModule in Root module(app module).

Then I identified, I've imported component in Routing Module only.

Declaring the component in my Root module(App Module) solves the problem.

Look at following demo code.

Here is your XML file for UI,

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <Button
        android:id="@+id/btnCapture"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Camera" />

</LinearLayout>

And here is your Java class file,

public class CameraDemoActivity extends Activity {
    int TAKE_PHOTO_CODE = 0;
    public static int count = 0;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        // Here, we are making a folder named picFolder to store
        // pics taken by the camera using this application.
        final String dir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES) + "/picFolder/";
        File newdir = new File(dir);
        newdir.mkdirs();

        Button capture = (Button) findViewById(R.id.btnCapture);
        capture.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {

                // Here, the counter will be incremented each time, and the
                // picture taken by camera will be stored as 1.jpg,2.jpg
                // and likewise.
                count++;
                String file = dir+count+".jpg";
                File newfile = new File(file);
                try {
                    newfile.createNewFile();
                }
                catch (IOException e)
                {
                }

                Uri outputFileUri = Uri.fromFile(newfile);

                Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);

                startActivityForResult(cameraIntent, TAKE_PHOTO_CODE);
            }
        });
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == TAKE_PHOTO_CODE && resultCode == RESULT_OK) {
            Log.d("CameraDemo", "Pic saved");
        }
    }
}

Note:

Specify the following permissions in your manifest file,

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

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

In your stylesheet:

div#content.myClass

Edit: These might help, too:

div#content.myClass.aSecondClass.aThirdClass /* Won't work in IE6, but valid */
div.firstClass.secondClass /* ditto */

and, per your example:

div#content.sectionA

Edit, 4 years later: Since this is super old and people keep finding it: don't use the tagNames in your selectors. #content.myClass is faster than div#content.myClass because the tagName adds a filtering step that you don't need. Use tagNames in selectors only where you must!

In my case i have a main.py that have dependencies with other files. After I build that app with py installer using this command:

pyinstaller --onefile --windowed main.py

I got the main.exe inside dist folder. I double clicked on this file, and I raised the error mentioned above. To fix this, I just copy the main.exe from dist directory to previous directory, which is the root directory of my main.py and the dependency files, and I got no error after run the main.exe.

It's perfectly safe as long as you always access the values through the struct via the . (dot) or -> notation.

What's not safe is taking the pointer of unaligned data and then accessing it without taking that into account.

Also, even though each item in the struct is known to be unaligned, it's known to be unaligned in a particular way, so the struct as a whole must be aligned as the compiler expects or there'll be trouble (on some platforms, or in future if a new way is invented to optimise unaligned accesses).

I'll try and answer several different things, however my contribution may not cover all of your questions. Maybe several of us can take different chunks out of this. However, this info should be helpful for you. Here we go..

Opening A Seperate File:

ChDir "[Path here]"                          'get into the right folder here
Workbooks.Open Filename:= "[Path here]"      'include the filename in this path

'copy data into current workbook or whatever you want here

ActiveWindow.Close                          'closes out the file

Opening A File With Specified Date If It Exists:

I'm not sure how to search your directory to see if a file exists, but in my case I wouldn't bother to search for it, I'd just try to open it and put in some error checking so that if it doesn't exist then display this message or do xyz.

Some common error checking statements:

On Error Resume Next   'if error occurs continues on to the next line (ignores it)

ChDir "[Path here]"                         
Workbooks.Open Filename:= "[Path here]"      'try to open file here

Or (better option):

if one doesn't exist then bring up either a message box or dialogue box to say "the file does not exist, would you like to create a new one?

you would most likely want to use the GoTo ErrorHandler shown below to achieve this

On Error GoTo ErrorHandler:

ChDir "[Path here]"                         
Workbooks.Open Filename:= "[Path here]"      'try to open file here

ErrorHandler:
'Display error message or any code you want to run on error here

Much more info on Error handling here: http://www.cpearson.com/excel/errorhandling.htm

Also if you want to learn more or need to know more generally in VBA I would recommend Siddharth Rout's site, he has lots of tutorials and example code here: http://www.siddharthrout.com/vb-dot-net-and-excel/

Hope this helps!

Example on how to ensure error code doesn't run EVERYtime:

if you debug through the code without the Exit Sub BEFORE the error handler you'll soon realize the error handler will be run everytime regarldess of if there is an error or not. The link below the code example shows a previous answer to this question.

  Sub Macro

    On Error GoTo ErrorHandler:

    ChDir "[Path here]"                         
    Workbooks.Open Filename:= "[Path here]"      'try to open file here

    Exit Sub      'Code will exit BEFORE ErrorHandler if everything goes smoothly
                  'Otherwise, on error, ErrorHandler will be run

    ErrorHandler:
    'Display error message or any code you want to run on error here

  End Sub

Also, look at this other question in you need more reference to how this works: goto block not working VBA

Possible reasons are 1. you didn't load React.JS into your page, 2. you loaded it after the above script into your page. Solution is load the JS file before the above shown script.

P.S

Possible solutions.

1. If you mention react in externals section inside webpack configuration, then you must load react js files directly into your html before bundle.js
2. Make sure you have the line import React from 'react';

To match a string that contains only those characters (or an empty string), try

"^[a-zA-Z0-9_]*$"

This works for .NET regular expressions, and probably a lot of other languages as well.

Breaking it down:

^ : start of string
[ : beginning of character group
a-z : any lowercase letter
A-Z : any uppercase letter
0-9 : any digit
_ : underscore
] : end of character group
* : zero or more of the given characters
$ : end of string

If you don't want to allow empty strings, use + instead of *.

As others have pointed out, some regex languages have a shorthand form for [a-zA-Z0-9_]. In the .NET regex language, you can turn on ECMAScript behavior and use \w as a shorthand (yielding ^\w*$ or ^\w+$). Note that in other languages, and by default in .NET, \w is somewhat broader, and will match other sorts of Unicode characters as well (thanks to Jan for pointing this out). So if you're really intending to match only those characters, using the explicit (longer) form is probably best.

 If Short.TryParse(editTransactionRow.pay_id, New Short) Then editTransactionRow.pay_id.ToString()

Because none of the above worked for me, I am adding another answer.

Goal: To vertically and horizontally align a div on a page using bootstrap 4 flexbox classes.

Step 1: Set your outermost div to a height of 100vh. This sets the height to 100% of the Veiwport Height. If you don't do this, nothing else will work. Setting it to a height of 100% is only relative to the parent, so if the parent is not the full height of the viewport, nothing will work. In the example below, I set the Body to 100vh.

Step 2: Set the container div to be the flexbox container with the d-flex class.

Step 3: Center div horizontally with the justify-content-center class.

Step 4: Center div vertically with the align-items-center

Step 5: Run page, view your vertically and horizontally centered div.

Note that there is no special class that needs to be set on the centered div itself (the child div)

<body style="background-color:#f2f2f2; height:100vh;">

<div class="h-100 d-flex justify-content-center align-items-center">
    <div style="height:600px; background-color:white; width:600px;">
</div>

</div>

</body>

You would also want to use refs on the element instead of using document.getElementById, it's just a slightly more robust thing.

From bash 4.0 onward, you can use Brace Expansion with fixed length strings. See below for the original announcement.

It will do just what you need, and does not require anything external to the shell.

$ echo {01..05}
01 02 03 04 05

for num in {01..05}
do
  echo $num
done
01
02
03
04
05

CHANGES, release bash-4.0, section 3

This is a terse description of the new features added to bash-4.0 since the release of bash-3.2.

. . .

z. Brace expansion now allows zero-padding of expanded numeric values and will add the proper number of zeroes to make sure all values contain the same number of digits.

I got the same trouble, in mobile device with Microsoft's Edge browser. I can solve the problem with: aria-haspopup="true". It need to add to the div and the :hover, :active, :focus for the other mobile browsers.

Example html:

<div class="left_bar" aria-haspopup="true">

CSS:

.left_bar:hover, .left_bar:focus, .left_bar:active{
    left: 0%;
    }

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

curl_setopt($ch, CURLOPT_PORT, 11740);

Bear in mind, you may face problems with SELinux:

Unable to make php curl request with port number

In your edit action, store the requesting url in the session hash, which is available across multiple requests:

session[:return_to] ||= request.referer

Then redirect to it in your update action, after a successful save:

redirect_to session.delete(:return_to)

You can use a generator to do this !

def sequence_generator(limit):  
    """ A generator to create strings of pattern -> string1,string2..stringN """
    inc  = 0
    while inc < limit:
        yield 'string'+str(inc)
        inc += 1

# to generate a generator. notice i have used () instead of []
a_generator  =  (s for s in sequence_generator(10))

# to generate a list
a_list  =  [s for s in sequence_generator(10)]

# to generate a string
a_string =  '['+", ".join(s for s in sequence_generator(10))+']'

At this time, there is no need for the script tag inside the iframe. This works for me (tested in Chrome, Firefox, IE11 and node-webkit 0.12):

<script>
window.onload = function() {
    var body = 'dddddd';
    var newWin = document.getElementById('printf').contentWindow;
    newWin.document.write(body);
    newWin.document.close(); //important!
    newWin.focus(); //IE fix
    newWin.print();
}
</script>

<iframe id="printf"></iframe>

Thanks to all answers, save my day.

I would use both meta, and JavaScript code and would have a link just in case.

<!DOCTYPE HTML>
<html lang="en-US">
    <head>
        <meta charset="UTF-8">
        <meta http-equiv="refresh" content="0; url=http://example.com">
        <script type="text/javascript">
            window.location.href = "http://example.com"
        </script>
        <title>Page Redirection</title>
    </head>
    <body>
        <!-- Note: don't tell people to `click` the link, just tell them that it is a link. -->
        If you are not redirected automatically, follow this <a href='http://example.com'>link to example</a>.
    </body>
</html>

For completeness, I think the best way, if possible, is to use server redirects, so send a 301 status code. This is easy to do via .htaccess files using Apache, or via numerous plugins using WordPress. I am sure there are also plugins for all the major content management systems. Also, cPanel has very easy configuration for 301 redirects if you have that installed on your server.

First register a receiver in your manifest.xml file:

    <receiver android:name="com.mileagelog.service.Broadcast_PowerUp" >
        <intent-filter>
            <action android:name="android.intent.action.ACTION_POWER_CONNECTED" />
            <action android:name="android.intent.action.ACTION_POWER_DISCONNECTED" />
        </intent-filter>
    </receiver>

and then write a broadcast for this receiver like:

public class Broadcast_PowerUp extends BroadcastReceiver {

  @Override
  public void onReceive(Context context, Intent intent) {
    String action = intent.getAction();

    if (action.equals(Intent.ACTION_POWER_CONNECTED)) {
        Toast.makeText(context, "Service_PowerUp Started",
                Toast.LENGTH_LONG).show();


    } else if (action.equals(Intent.ACTION_POWER_DISCONNECTED)) {



        Toast.makeText(context, "Service_PowerUp Stoped", Toast.LENGTH_LONG)
        .show();
    }
  }
}

Another handy difference (in English where accents are uncommon) is that an InvariantCulture comparison compares the entire strings by case-insensitive first, and then if necessary (and requested) distinguishes by case after first comparing only on the distinct letters. (You can also do a case-insensitive comparison, of course, which won't distinguish by case.) Corrected: Accented letters are considered to be another flavor of the same letters and the string is compared first ignoring accents and then accounting for them if the general letters all match (much as with differing case except not ultimately ignored in a case-insensitive compare). This groups accented versions of the otherwise same word near each other instead of completely separate at the first accent difference. This is the sort order you would typically find in a dictionary, with capitalized words appearing right next to their lowercase equivalents, and accented letters being near the corresponding unaccented letter.

An ordinal comparison compares strictly on the numeric character values, stopping at the first difference. This sorts capitalized letters completely separate from the lowercase letters (and accented letters presumably separate from those), so capitalized words would sort nowhere near their lowercase equivalents.

InvariantCulture also considers capitals to be greater than lower case, whereas Ordinal considers capitals to be less than lowercase (a holdover of ASCII from the old days before computers had lowercase letters, the uppercase letters were allocated first and thus had lower values than the lowercase letters added later).

For example, by Ordinal: "0" < "9" < "A" < "Ab" < "Z" < "a" < "aB" < "ab" < "z" < "Á" < "Áb" < "á" < "áb"

And by InvariantCulture: "0" < "9" < "a" < "A" < "á" < "Á" < "ab" < "aB" < "Ab" < "áb" < "Áb" < "z" < "Z"

You're passing the same model to the partial view as is being passed to the main view, and they are different types. The model is a DbSet of Notes, where you need to pass in a single Note.

You can do this by adding a parameter, which I'm guessing as it's the create form would be a new Note

@Html.Partial("_CreateNote", new QuickNotes.Models.Note())

Support for OFFSET and LIMIT was recently added to DB2 for i 7.1 and 7.2. You need the following DB PTF group levels to get this support:

• SF99702 level 9 for IBM i 7.2
• SF99701 level 38 for IBM i 7.1
