I recently stumbled up on the same problem. Here is the synopsis of my solution:

Basic constituent code blocks needed

The following are the required basic code blocks of your client application

1. Session request section: request a session with the provider
2. Session authentication section: provide credentials to the provider
3. Client section: create the Client
4. Security Header section: add the WS-Security Header to the Client
5. Consumption section: consume available operations (or methods) as needed

What modules do you need?

Many suggested to use Python modules such as urllib2 ; however, none of the modules work-at least for this particular project.

So, here is the list of the modules you need to get. First of all, you need to download and install the latest version of suds from the following link:

pypi.python.org/pypi/suds-jurko/0.4.1.jurko.2

Additionally, you need to download and install requests and suds_requests modules from the following links respectively ( disclaimer: I am new to post in here, so I can't post more than one link for now).

pypi.python.org/pypi/requests

pypi.python.org/pypi/suds_requests/0.1

Once you successfully download and install these modules, you are good to go.

The code

Following the steps outlined earlier, the code looks like the following: Imports:

import logging
from suds.client import Client
from suds.wsse import *
from datetime import timedelta,date,datetime,tzinfo
import requests
from requests.auth import HTTPBasicAuth
import suds_requests

Session request and authentication:

username=input('Username:')
password=input('password:')
session = requests.session()
session.auth=(username, password)

Create the Client:

client = Client(WSDL_URL, faults=False, cachingpolicy=1, location=WSDL_URL, transport=suds_requests.RequestsTransport(session))

Add WS-Security Header:

...
addSecurityHeader(client,username,password)
....

def addSecurityHeader(client,username,password):
    security=Security()
    userNameToken=UsernameToken(username,password)
    timeStampToken=Timestamp(validity=600)
    security.tokens.append(userNameToken)
    security.tokens.append(timeStampToken)
    client.set_options(wsse=security)

Please note that this method creates the security header depicted in Fig.1. So, your implementation may vary depending on the correct security header format provided by the owner of the service you are consuming.

Consume the relevant method (or operation) :

result=client.service.methodName(Inputs)

Logging:

One of the best practices in such implementations as this one is logging to see how the communication is executed. In case there is some issue, it makes debugging easy. The following code does basic logging. However, you can log many aspects of the communication in addition to the ones depicted in the code.

logging.basicConfig(level=logging.INFO) 
logging.getLogger('suds.client').setLevel(logging.DEBUG) 
logging.getLogger('suds.transport').setLevel(logging.DEBUG)

Result:

Here is the result in my case. Note that the server returned HTTP 200. This is the standard success code for HTTP request-response.

(200, (collectionNodeLmp){
   timestamp = 2014-12-03 00:00:00-05:00
   nodeLmp[] = 
      (nodeLmp){
         pnodeId = 35010357
         name = "YADKIN"
         mccValue = -0.19
         mlcValue = -0.13
         price = 36.46
         type = "500 KV"
         timestamp = 2014-12-03 01:00:00-05:00
         errorCodeId = 0
      },
      (nodeLmp){
         pnodeId = 33138769
         name = "ZION 1"
         mccValue = -0.18
         mlcValue = -1.86
         price = 34.75
         type = "Aggregate"
         timestamp = 2014-12-03 01:00:00-05:00
         errorCodeId = 0
      },
 })

I ran into the need to allow decimal values, so I used not Value like '%[^0-9.]%'

ECMAScript 6 introduced String.prototype.includes:

const string = "foo";_x000D_
const substring = "oo";_x000D_
_x000D_
console.log(string.includes(substring));

includes doesn’t have Internet Explorer support, though. In ECMAScript 5 or older environments, use String.prototype.indexOf, which returns -1 when a substring cannot be found:

var string = "foo";_x000D_
var substring = "oo";_x000D_
_x000D_
console.log(string.indexOf(substring) !== -1);

Use requests.packages.urllib3.disable_warnings() and verify=False on requests methods.

import requests
from urllib3.exceptions import InsecureRequestWarning

# Suppress only the single warning from urllib3 needed.
requests.packages.urllib3.disable_warnings(category=InsecureRequestWarning)

# Set `verify=False` on `requests.post`.
requests.post(url='https://example.com', data={'bar':'baz'}, verify=False)

Try this:

private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
        switch (e.Key.ToString())
        {
                case "Return":
                        MessageBox.Show(" Enter pressed ");
                        break;
         }
}

If you know part of the subnet (i.e. 10.3 in this example), then this will grab any addresses that are in the given subnet:

PS C:\> [System.Net.Dns]::GetHostAddresses("MyPC") | foreach { $_.IPAddressToString | findstr "10.3."}

Ensure you have an index on your firstname and lastname columns and go with 1. This really won't have much of a performance impact at all.

EDIT: After @Dems comment regarding spamming the plan cache ,a better solution might be to create a computed column on the existing table (or a separate view) which contained a concatenated Firstname + Lastname value, thus allowing you to execute a query such as

SELECT City 
FROM User 
WHERE Fullname in (@fullnames)

where @fullnames looks a bit like "'JonDoe', 'JaneDoe'" etc

Well, here's an example for overloaded constructors.

public class Employee
{
   private String name;
   private int age;

   public Employee()
   {
      System.out.println("We are inside Employee() constructor");
   }

   public Employee(String name)
   {
      System.out.println("We are inside Employee(String name) constructor");
      this.name = name;
   }

   public Employee(String name, int age)
   {
      System.out.println("We are inside Employee(String name, int age) constructor");
      this.name = name;
      this.age = age;
   }

   public Employee(int age)
   {
      System.out.println("We are inside Employee(int age) constructor");
      this.age = age; 
   }

   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;
   }
}

In the above example you can see overloaded constructors. Name of the constructors is same but each constructors has different parameters.

Here are some resources which throw more light on constructor overloading in java,

How about using strtr() to substitute all of your other delimiters with the first one?

private function multiExplode($delimiters,$string) {
    return explode(
        $delimiters[0],
        strtr(
            $string,
            array_combine(
                array_slice(    $delimiters, 1  ),
                array_fill(
                    0,
                    count($delimiters)-1,
                    array_shift($delimiters)
                )
            )
        )
    );
}

It's sort of unreadable, I guess, but I tested it as working over here.

One-liners ftw!

Apart from accepted answer, following is also valid

Model.find() can accept array of ids, and will return all records which matches. Model.find_by_id(123) also accept array but will only process first id value present in array

Model.find([1,2,3])
Model.find_by_id([1,2,3])

In Java8 you can use streams:

public static Carnet findByCodeIsIn(Collection<Carnet> listCarnet, String codeIsIn) {
    return listCarnet.stream().filter(carnet -> codeIsIn.equals(carnet.getCodeIsin())).findFirst().orElse(null);
}

Additionally, in case you have many different objects (not only Carnet) or you want to find it by different properties (not only by cideIsin), you could build an utility class, to ecapsulate this logic in it:

public final class FindUtils {
    public static <T> T findByProperty(Collection<T> col, Predicate<T> filter) {
        return col.stream().filter(filter).findFirst().orElse(null);
    }
}

public final class CarnetUtils {
    public static Carnet findByCodeTitre(Collection<Carnet> listCarnet, String codeTitre) {
        return FindUtils.findByProperty(listCarnet, carnet -> codeTitre.equals(carnet.getCodeTitre()));
    }

    public static Carnet findByNomTitre(Collection<Carnet> listCarnet, String nomTitre) {
        return FindUtils.findByProperty(listCarnet, carnet -> nomTitre.equals(carnet.getNomTitre()));
    }

    public static Carnet findByCodeIsIn(Collection<Carnet> listCarnet, String codeIsin) {
        return FindUtils.findByProperty(listCarnet, carnet -> codeIsin.equals(carnet.getCodeIsin()));
    }
}

Create an XML layout first in your project's res/layout/main.xml folder:

<?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" >
    <Button
        android:id="@+id/addBtn"
        android:text="Add New Item"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:onClick="addItems"/>
    <ListView
        android:id="@android:id/list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:drawSelectorOnTop="false"
    />
</LinearLayout>

This is a simple layout with a button on the top and a list view on the bottom. Note that the ListView has the id @android:id/list which defines the default ListView a ListActivity can use.

public class ListViewDemo extends ListActivity {
    //LIST OF ARRAY STRINGS WHICH WILL SERVE AS LIST ITEMS
    ArrayList<String> listItems=new ArrayList<String>();

    //DEFINING A STRING ADAPTER WHICH WILL HANDLE THE DATA OF THE LISTVIEW
    ArrayAdapter<String> adapter;

    //RECORDING HOW MANY TIMES THE BUTTON HAS BEEN CLICKED
    int clickCounter=0;

    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.main);
        adapter=new ArrayAdapter<String>(this,
            android.R.layout.simple_list_item_1,
            listItems);
        setListAdapter(adapter);
    }

    //METHOD WHICH WILL HANDLE DYNAMIC INSERTION
    public void addItems(View v) {
        listItems.add("Clicked : "+clickCounter++);
        adapter.notifyDataSetChanged();
    }
}

android.R.layout.simple_list_item_1 is the default list item layout supplied by Android, and you can use this stock layout for non-complex things.

listItems is a List which holds the data shown in the ListView. All the insertion and removal should be done on listItems; the changes in listItems should be reflected in the view. That's handled by ArrayAdapter<String> adapter, which should be notified using:

adapter.notifyDataSetChanged();

An Adapter is instantiated with 3 parameters: the context, which could be your activity/listactivity; the layout of your individual list item; and lastly, the list, which is the actual data to be displayed in the list.

Outside of your technique, why not use the standard Java JarFile class to get the references you want? From there most of your problems should go away.

I was asking the same too. Another solution is you could overload your method:

void remove_id(EmployeeClass);
void remove_id(ProductClass);
void remove_id(DepartmentClass);

in the call the argument will fit accordingly the object you pass. but then you will have to repeat yourself

void remove_id(EmployeeClass _obj) {
    int saveId = _obj->id;
    ...
};

void remove_id(ProductClass _obj) {
    int saveId = _obj->id;
    ...
};

void remove_id(DepartmentClass _obj) {
    int saveId = _obj->id;
    ...
};

This code sample is taken from csharp-examples.net, written by Jan Slama:

To find nodes in an XML file you can use XPath expressions. Method XmlNode.Selec­tNodes returns a list of nodes selected by the XPath string. Method XmlNode.Selec­tSingleNode finds the first node that matches the XPath string.

XML:

<Names>
    <Name>
        <FirstName>John</FirstName>
        <LastName>Smith</LastName>
    </Name>
    <Name>
        <FirstName>James</FirstName>
        <LastName>White</LastName>
    </Name>
</Names>

CODE:

XmlDocument xml = new XmlDocument();
xml.LoadXml(myXmlString); // suppose that myXmlString contains "<Names>...</Names>"

XmlNodeList xnList = xml.SelectNodes("/Names/Name");
foreach (XmlNode xn in xnList)
{
  string firstName = xn["FirstName"].InnerText;
  string lastName = xn["LastName"].InnerText;
  Console.WriteLine("Name: {0} {1}", firstName, lastName);
}

You need to add C:\xampp\php to your PATH Environment Variable, Only after then you would be able to execute php command line from outside php_home.

Try over-riding CSS using !important

like this

It is more efficient to send the files directly.

The base64 encoding of Content-Type: multipart/form-data adds an extra 33% overhead. If the server supports it, it is more efficient to send the files directly:

Doing Multiple $http.post Requests Directly from a FileList

$scope.upload = function(url, fileList) {
    var config = {
      headers: { 'Content-Type': undefined },
      transformResponse: angular.identity
    };
    var promises = fileList.map(function(file) {
      return $http.post(url, file, config);
    });
    return $q.all(promises);
};

When sending a POST with a File object, it is important to set 'Content-Type': undefined. The XHR send method will then detect the File object and automatically set the content type.

Working Demo of "select-ng-files" Directive that Works with ng-model¹

The <input type=file> element does not by default work with the ng-model directive. It needs a custom directive:

angular.module("app",[]);

angular.module("app").directive("selectNgFiles", function() {
  return {
    require: "ngModel",
    link: function postLink(scope,elem,attrs,ngModel) {
      elem.on("change", function(e) {
        var files = elem[0].files;
        ngModel.$setViewValue(files);
      })
    }
  }
});

<script src="//unpkg.com/angular/angular.js"></script>
  <body ng-app="app">
    <h1>AngularJS Input `type=file` Demo</h1>
    
    <input type="file" select-ng-files ng-model="fileList" multiple>
    
    <h2>Files</h2>
    <div ng-repeat="file in fileList">

Today March 6, 2013, Microsoft released SQL Server Data Tools – Business Intelligence for Visual Studio 2012 (SSDT BI) templates. With SSDT BI for Visual Studio 2012 you can develop and deploy SQL Server Business intelligence projects. Projects created in Visual Studio 2010 can be opened in Visual Studio 2012 and the other way around without upgrading or downgrading – it just works.

The download/install is named to ensure you get the SSDT templates that contain the Business Intelligence projects. The setup for these tools is now available from the web and can be downloaded in multiple languages right here: http://www.microsoft.com/download/details.aspx?id=36843

I think I got there in the end.

The task is like this:

- name: Populate genders
  set_fact:
    genders: "{{ genders|default({}) | combine( {item.item.name: item.stdout} ) }}"
  with_items: "{{ people.results }}"

It loops through each of the dicts (item) in the people.results array, each time creating a new dict like {Bob: "male"}, and combine()s that new dict in the genders array, which ends up like:

{
    "Bob": "male",
    "Thelma": "female"
}

It assumes the keys (the name in this case) will be unique.

I then realised I actually wanted a list of dictionaries, as it seems much easier to loop through using with_items:

- name: Populate genders
  set_fact:
    genders: "{{ genders|default([]) + [ {'name': item.item.name, 'gender': item.stdout} ] }}"
  with_items: "{{ people.results }}"

This keeps combining the existing list with a list containing a single dict. We end up with a genders array like this:

[
    {'name': 'Bob', 'gender': 'male'},
    {'name': 'Thelma', 'gender': 'female'}
]

No need of use addition CSS/JS (Tested)

1. data-toggle="dropdown" - for Clickable (can use Mobile as well web)
2. data-hover="dropdown" - for Hover (web only, because mobile doesn't have feature HOVER)

Works fine on Mobile as well :)

Output

I would use a nice UML example.

Take a university that has 1 to 20 different departments and each department has 1 to 5 professors. There is a composition link between a University and its' departments. There is an aggregation link between a department and its' professors.

Composition is just a STRONG aggregation, if the university is destroyed then the departments should also be destroyed. But we shouldn't kill the professors even if their respective departments disappear.

In java :

public class University {

     private List<Department> departments;

     public void destroy(){
         //it's composition, when I destroy a university I also destroy the departments. they cant live outside my university instance
         if(departments!=null)
             for(Department d : departments) d.destroy();
         departments.clean();
         departments = null;
     }
}

public class Department {

     private List<Professor> professors;
     private University university;

     Department(University univ){
         this.university = univ;
         //check here univ not null throw whatever depending on your needs
     }

     public void destroy(){
         //It's aggregation here, we just tell the professor they are fired but they can still keep living
         for(Professor p:professors)
             p.fire(this);
         professors.clean();
         professors = null;
     }
}

public class Professor {

     private String name;
     private List<Department> attachedDepartments;

     public void destroy(){

     }

     public void fire(Department d){
         attachedDepartments.remove(d);
     }
}

Something around this.

EDIT: an example as requested

public class Test
{
    public static void main(String[] args)
    {
        University university = new University();
        //the department only exists in the university
        Department dep = university.createDepartment();
        // the professor exists outside the university
        Professor prof = new Professor("Raoul");
        System.out.println(university.toString());
        System.out.println(prof.toString());

        dep.assign(prof);
        System.out.println(university.toString());
        System.out.println(prof.toString());
        dep.destroy();

        System.out.println(university.toString());
        System.out.println(prof.toString());

The implementation is debatable as it depends on how you need to handle creation, hiring deletion etc. Unrelevant for the OP

This solution essentially draws the image as 'aspect fit' within the given rect.

CGSize itemSize = CGSizeMake(80, 80);
UIGraphicsBeginImageContextWithOptions(itemSize, NO, UIScreen.mainScreen.scale);
UIImage *image = cell.imageView.image;

CGRect imageRect;
if(image.size.height > image.size.width) {
    CGFloat width = itemSize.height * image.size.width / image.size.height;
    imageRect = CGRectMake((itemSize.width - width) / 2, 0, width, itemSize.height);
} else {
    CGFloat height = itemSize.width * image.size.height / image.size.width;
    imageRect = CGRectMake(0, (itemSize.height - height) / 2, itemSize.width, height);
}

[cell.imageView.image drawInRect:imageRect];
cell.imageView.image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

This should provide a uniform distribution over the range [low, high) without using floats, as long as the overall range is less than RAND_MAX.

uint32_t rand_range_low(uint32_t low, uint32_t high)
{
    uint32_t val;
    // only for 0 < range <= RAND_MAX
    assert(low < high);
    assert(high - low <= RAND_MAX);

    uint32_t range = high-low;
    uint32_t scale = RAND_MAX/range;
    do {
        val = rand();
    } while (val >= scale * range); // since scale is truncated, pick a new val until it's lower than scale*range
    return val/scale + low;
}

and for values greater than RAND_MAX you want something like

uint32_t rand_range(uint32_t low, uint32_t high)
{
    assert(high>low);
    uint32_t val;
    uint32_t range = high-low;
    if (range < RAND_MAX)
        return rand_range_low(low, high);
    uint32_t scale = range/RAND_MAX;
    do {
        val = rand() + rand_range(0, scale) * RAND_MAX; // scale the initial range in RAND_MAX steps, then add an offset to get a uniform interval
    } while (val >= range);
    return val + low;
}

This is roughly how std::uniform_int_distribution does things.

I implemented it in the following way. I wanted a generic MakeRequest method that could call my API and receive content for the body of the request - and also deserialise the response into the desired type. I create a Dictionary<string, string> object to house the content to be submitted, and then set the HttpRequestMessage Content property with it:

Generic method to call the API:

    private static T MakeRequest<T>(string httpMethod, string route, Dictionary<string, string> postParams = null)
    {
        using (var client = new HttpClient())
        {
            HttpRequestMessage requestMessage = new HttpRequestMessage(new HttpMethod(httpMethod), $"{_apiBaseUri}/{route}");

            if (postParams != null)
                requestMessage.Content = new FormUrlEncodedContent(postParams);   // This is where your content gets added to the request body


            HttpResponseMessage response = client.SendAsync(requestMessage).Result;

            string apiResponse = response.Content.ReadAsStringAsync().Result;
            try
            {
                // Attempt to deserialise the reponse to the desired type, otherwise throw an expetion with the response from the api.
                if (apiResponse != "")
                    return JsonConvert.DeserializeObject<T>(apiResponse);
                else
                    throw new Exception();
            }
            catch (Exception ex)
            {
                throw new Exception($"An error ocurred while calling the API. It responded with the following message: {response.StatusCode} {response.ReasonPhrase}");
            }
        }
    }

Call the method:

    public static CardInformation ValidateCard(string cardNumber, string country = "CAN")
    { 
        // Here you create your parameters to be added to the request content
        var postParams = new Dictionary<string, string> { { "cardNumber", cardNumber }, { "country", country } };
        // make a POST request to the "cards" endpoint and pass in the parameters
        return MakeRequest<CardInformation>("POST", "cards", postParams);
    }

This will allocate storage as need and shouldn't affect performance.

Java ArrayList has an indexOf method. Java arrays have no such method.

You need to remove the scanner closing lines: scan.close();

It happened to me before and that was the reason.

git pull and git rebase are not interchangeable, but they are closely connected.

git pull fetches the latest changes of the current branch from a remote and applies those changes to your local copy of the branch. Generally this is done by merging, i.e. the local changes are merged into the remote changes. So git pull is similar to git fetch & git merge.

Rebasing is an alternative to merging. Instead of creating a new commit that combines the two branches, it moves the commits of one of the branches on top of the other.

You can pull using rebase instead of merge (git pull --rebase). The local changes you made will be rebased on top of the remote changes, instead of being merged with the remote changes.

Atlassian has some excellent documentation on merging vs. rebasing.

In the Javascript community, lots of people argue that OOP should not be used because the prototype model does not allow to do a strict and robust OOP natively. However, I don't think that OOP is a matter of langage but rather a matter of architecture.

If you want to use a real strong OOP in Javascript/Node, you can have a look at the full-stack open source framework Danf. It provides all needed features for a strong OOP code (classes, interfaces, inheritance, dependency-injection, ...). It also allows you to use the same classes on both the server (node) and client (browser) sides. Moreover, you can code your own danf modules and share them with anybody thanks to Npm.

std::copy does the job as far as moving elements is concerned:

 #include <algorithm>

 std::copy(array+3, array+5, array+2);

Note that the precondition for copy is that the destination must not be in the source range. It's permissible for the ranges to overlap.

Also, because of the way arrays work in C++, this doesn't "shorten" the array. It just shifts elements around within it. There is no way to change the size of an array, but if you're using a separate integer to track its "size" meaning the size of the part you care about, then you can of course decrement that.

So, the array you'll end up with will be as if it were initialized with:

int array[] = {1,2,4,5,5};

I found solution. It's was because I had 2 setter with same name but different type.

My class had id property int that I replaced with Integer when à Hibernitify my object.

But apparently, I forgot to remove setters and I had :

/**
 * @param id
 *            the id to set
 */
public void setId(int id) {
    this.id = id;
}

/**
 * @param id
 *            the id to set
 */
public void setId(Integer id) {
    this.id = id;
}

When I removed this setter, rest resquest work very well.

Intead to throw unmarshalling error or reflect class error. Exception HttpMediaTypeNotSupportedException seams really strange here.

I hope this stackoverflow could be help someone else.

SIDE NOTE

You can check your Spring server console for the following error message:

Failed to evaluate Jackson deserialization for type [simple type, class your.package.ClassName]: com.fasterxml.jackson.databind.JsonMappingException: Conflicting setter definitions for property "propertyname"

Then you can be sure you are dealing with the issue mentioned above.

A Meteor app does not, by default, add any X-Powered-By headers to HTTP responses, as you might find in various PHP apps. The headers look like:

$ curl -I https://atmosphere.meteor.com  HTTP/1.1 200 OK content-type: text/html; charset=utf-8 date: Tue, 31 Dec 2013 23:12:25 GMT connection: keep-alive 

However, this doesn't mask that Meteor was used. Viewing the source of a Meteor app will look very distinctive.

<script type="text/javascript"> __meteor_runtime_config__ = {"meteorRelease":"0.6.3.1","ROOT_URL":"http://atmosphere.meteor.com","serverId":"62a4cf6a-3b28-f7b1-418f-3ddf038f84af","DDP_DEFAULT_CONNECTION_URL":"ddp+sockjs://ddp--****-atmosphere.meteor.com/sockjs"}; </script> 

If you're trying to avoid people being able to tell you are using Meteor even by viewing source, I don't think that's possible.

One thing to keep in mind is that Javascript runs on the client, and not on the server. You can't really "load a file" from the server in Javascript. What happens is that Javascript sends a request to the server, and the server sends back the contents of the requested file. How does Javascript receive the contents? That's what the callback function is for. In Edward's case, that is

    client.onreadystatechange = function() {

and in danb's case, it is

 function(data) {

This function is called whenever the data happen to arrive. The jQuery version implicitly uses Ajax, it just makes the coding easier by encapsulating that code in the library.

All of the DISPATCH_QUEUE_PRIORITY_X queues are concurrent queues (meaning they can execute multiple tasks at once), and are FIFO in the sense that tasks within a given queue will begin executing using "first in, first out" order. This is in comparison to the main queue (from dispatch_get_main_queue()), which is a serial queue (tasks will begin executing and finish executing in the order in which they are received).

So, if you send 1000 dispatch_async() blocks to DISPATCH_QUEUE_PRIORITY_DEFAULT, those tasks will start executing in the order you sent them into the queue. Likewise for the HIGH, LOW, and BACKGROUND queues. Anything you send into any of these queues is executed in the background on alternate threads, away from your main application thread. Therefore, these queues are suitable for executing tasks such as background downloading, compression, computation, etc.

Note that the order of execution is FIFO on a per-queue basis. So if you send 1000 dispatch_async() tasks to the four different concurrent queues, evenly splitting them and sending them to BACKGROUND, LOW, DEFAULT and HIGH in order (ie you schedule the last 250 tasks on the HIGH queue), it's very likely that the first tasks you see starting will be on that HIGH queue as the system has taken your implication that those tasks need to get to the CPU as quickly as possible.

Note also that I say "will begin executing in order", but keep in mind that as concurrent queues things won't necessarily FINISH executing in order depending on length of time for each task.

As per Apple:

https://developer.apple.com/library/content/documentation/General/Conceptual/ConcurrencyProgrammingGuide/OperationQueues/OperationQueues.html

A concurrent dispatch queue is useful when you have multiple tasks that can run in parallel. A concurrent queue is still a queue in that it dequeues tasks in a first-in, first-out order; however, a concurrent queue may dequeue additional tasks before any previous tasks finish. The actual number of tasks executed by a concurrent queue at any given moment is variable and can change dynamically as conditions in your application change. Many factors affect the number of tasks executed by the concurrent queues, including the number of available cores, the amount of work being done by other processes, and the number and priority of tasks in other serial dispatch queues.

Basically, if you send those 1000 dispatch_async() blocks to a DEFAULT, HIGH, LOW, or BACKGROUND queue they will all start executing in the order you send them. However, shorter tasks may finish before longer ones. Reasons behind this are if there are available CPU cores or if the current queue tasks are performing computationally non-intensive work (thus making the system think it can dispatch additional tasks in parallel regardless of core count).

The level of concurrency is handled entirely by the system and is based on system load and other internally determined factors. This is the beauty of Grand Central Dispatch (the dispatch_async() system) - you just make your work units as code blocks, set a priority for them (based on the queue you choose) and let the system handle the rest.

So to answer your above question: you are partially correct. You are "asking that code" to perform concurrent tasks on a global concurrent queue at the specified priority level. The code in the block will execute in the background and any additional (similar) code will execute potentially in parallel depending on the system's assessment of available resources.

The "main" queue on the other hand (from dispatch_get_main_queue()) is a serial queue (not concurrent). Tasks sent to the main queue will always execute in order and will always finish in order. These tasks will also be executed on the UI Thread so it's suitable for updating your UI with progress messages, completion notifications, etc.

Yes, definitely don't write your own algorithm. Java has lots of cryptography APIs.

If the OS you are installing upon has a keystore, then you could use that to store your crypto keys that you will need to encrypt and decrypt the sensitive data in your configuration or other files.

ok, for me :

<style type="text/css">
    div{
        position: relative;
        display: inline-block;
        width:25px;
        height:25px;
    }
</style>
<div>toto</div>

It's very simple to define a function inside razor.

@functions {

    public static HtmlString OrderedList(IEnumerable<string> items)
    { }
}

So you can call a the function anywhere. Like

@Functions.OrderedList(new[] { "Blue", "Red", "Green" })

However, this same work can be done through helper too. As an example

@helper OrderedList(IEnumerable<string> items){
    <ol>
        @foreach(var item in items){
            <li>@item</li>
        }
    </ol>
}

So what is the difference?? According to this previous post both @helpers and @functions do share one thing in common - they make code reuse a possibility within Web Pages. They also share another thing in common - they look the same at first glance, which is what might cause a bit of confusion about their roles. However, they are not the same. In essence, a helper is a reusable snippet of Razor sytnax exposed as a method, and is intended for rendering HTML to the browser, whereas a function is static utility method that can be called from anywhere within your Web Pages application. The return type for a helper is always HelperResult, whereas the return type for a function is whatever you want it to be.

To have a constant date format irrespective of the computer settings, you must use 3 different input elements to capture day, month, and year respectively. However, you need to validate the user input to ensure that you have a valid date as shown bellow

<input id="txtDay" type="text" placeholder="DD" />

<input id="txtMonth" type="text" placeholder="MM" />

<input id="txtYear" type="text" placeholder="YYYY" />
<button id="but" onclick="validateDate()">Validate</button>


  function validateDate() {
    var date = new Date(document.getElementById("txtYear").value, document.getElementById("txtMonth").value, document.getElementById("txtDay").value);

    if (date == "Invalid Date") {
        alert("jnvalid date");

    }
}

Here's a solution that allows you to return the key as well and only does one loop. It sorts the Object's entries (by val) and then returns the first and last one.

Additionally, it returns the sorted Object which can replace the existing Object so that future sorts will be faster because it will already be semi-sorted = better than O(n). It's important to note that Objects retain their order in ES6.

const maxMinVal = (obj) => {_x000D_
  const sortedEntriesByVal = Object.entries(obj).sort(([, v1], [, v2]) => v1 - v2);_x000D_
_x000D_
  return {_x000D_
    min: sortedEntriesByVal[0],_x000D_
    max: sortedEntriesByVal[sortedEntriesByVal.length - 1],_x000D_
    sortedObjByVal: sortedEntriesByVal.reduce((r, [k, v]) => ({ ...r, [k]: v }), {}),_x000D_
  };_x000D_
};_x000D_
_x000D_
const obj = {_x000D_
  a: 4, b: 0.5, c: 0.35, d: 5_x000D_
};_x000D_
_x000D_
console.log(maxMinVal(obj));

I think we need to write more specific media query. Make sure if you write one media query it should be not effect to other view (Mob,Tab,Desk) otherwise it can be trouble. I would like suggest to write one basic media query for respective device which cover both view and one orientation media query that you can specific code more about orientation view its for good practice. we Don't need to write both media orientation query at same time. You can refer My below example. I am sorry if my English writing is not much good. Ex:

For Mobile

@media screen and (max-width:767px) {

Thanks, Jitu

In C it was a nice way to implement something like an variant.

enum possibleTypes{
  eInt,
  eDouble,
  eChar
}


struct Value{

    union Value {
      int iVal_;
      double dval;
      char cVal;
    } value_;
    possibleTypes discriminator_;
} 

switch(val.discriminator_)
{
  case eInt: val.value_.iVal_; break;

In times of litlle memory this structure is using less memory than a struct that has all the member.

By the way C provides

    typedef struct {
      unsigned int mantissa_low:32;      //mantissa
      unsigned int mantissa_high:20;
      unsigned int exponent:11;         //exponent
      unsigned int sign:1;
    } realVal;

to access bit values.

You can use strtotime() for time calculation. Here is an example:

$checkTime = strtotime('09:00:59');
echo 'Check Time : '.date('H:i:s', $checkTime);
echo '<hr>';

$loginTime = strtotime('09:01:00');
$diff = $checkTime - $loginTime;
echo 'Login Time : '.date('H:i:s', $loginTime).'<br>';
echo ($diff < 0)? 'Late!' : 'Right time!'; echo '<br>';
echo 'Time diff in sec: '.abs($diff);

echo '<hr>';

$loginTime = strtotime('09:00:59');
$diff = $checkTime - $loginTime;
echo 'Login Time : '.date('H:i:s', $loginTime).'<br>';
echo ($diff < 0)? 'Late!' : 'Right time!';

echo '<hr>';

$loginTime = strtotime('09:00:00');
$diff = $checkTime - $loginTime;
echo 'Login Time : '.date('H:i:s', $loginTime).'<br>';
echo ($diff < 0)? 'Late!' : 'Right time!';

Demo

Check the already-asked question - how to get time difference in minutes:

Subtract the past-most one from the future-most one and divide by 60.

Times are done in unix format so they're just a big number showing the number of seconds from January 1 1970 00:00:00 GMT

You need to use a Collection List. You cannot re-dimension an array.

Create a class that implements webviewclient and add the following code that allows ovveriding the url string as shown below. You can see these [example][1]

public class myWebClient extends WebViewClient {

    @Override 
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
         view.loadUrl(url); 
         return true;
     }
}

On your constructor, create a webview object as shown below.

   web = new WebView(this); web.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.FILL_PARENT)); 

Then add the following code to perform loading of urls inside your app

       WebSettings settings=web.getSettings(); 
    settings.setJavaScriptEnabled(true); 
    
    web.loadUrl("http://www.facebook.com");
    web.setWebViewClient(new myWebClient()); 
   
 web.setWebChromeClient(new WebChromeClient() {
      // 
      //
    }

Swift 3

Time format 24 hours to 12 hours

let dateAsString = "13:15"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "HH:mm"

let date = dateFormatter.date(from: dateAsString)
dateFormatter.dateFormat = "h:mm a"
let Date12 = dateFormatter.string(from: date!)
print("12 hour formatted Date:",Date12)

output will be 12 hour formatted Date: 1:15 PM

Time format 12 hours to 24 hours

let dateAsString = "1:15 PM"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "h:mm a"

let date = dateFormatter.date(from: dateAsString)
dateFormatter.dateFormat = "HH:mm"

let Date24 = dateFormatter.string(from: date!)
print("24 hour formatted Date:",Date24)

output will be 24 hour formatted Date: 13:15

In addition to the 3 floated column structure (which I would suggest as well), you have to insert a clearfix to prevent layoutproblems with elements after the columncontainer (keep the columncontainer in the flow, so to speak...).

<div id="contentBox" class="clearfix">
....
</div>

CSS:

.clearfix { zoom: 1; }
.clearfix:before, .clearfix:after { content: "\0020"; display: block; height: 0; overflow: hidden; }
.clearfix:after { clear: both; }

To further clear any confusion about the two approach i.e use of

1. @PostConstruct and
2. init-method="init"

From personal experience, I realized that using (1) only works in a servlet container, while (2) works in any environment, even in desktop applications. So, if you would be using Spring in a standalone application, you would have to use (2) to carry out that "call this method after initialization.

There is no out of the box DateTime picker for WPF..

There are however a lot of third party DateTime pickers of course :)

Just do a quick google to find more!

Try using this:

$(".move_to").on("click", function(e){
    e.preventDefault();
    $('#contactsForm').attr('action', "/test1").submit();
});

Moving the order in which you use .preventDefault() might fix your issue. You also didn't use function(e) so e.preventDefault(); wasn't working.

Here it is working: http://jsfiddle.net/TfTwe/1/ - first of all, click the 'Check action attribute.' link. You'll get an alert saying undefined. Then click 'Set action attribute.' and click 'Check action attribute.' again. You'll see that the form's action attribute has been correctly set to /test1.

Try this way:

dataGridView.CurrentCell.Value = newValue;

dataGridView.EndEdit();

dataGridView.CurrentCell.Value = newValue;

dataGridView.EndEdit();

Need to write two times...

One of the benefits is you can use it in multiple views and have a consistent label text. It is also used by asp.net MVC scaffolding to generate the labels text and makes it easier to generate meaningful text

[Display(Name = "Wild and Crazy")]
public string WildAndCrazyProperty { get; set; }

"Wild and Crazy" shows up consistently wherever you use the property in your application.

Sometimes this is not flexible as you might want to change the text in some view. In that case, you will have to use custom markup like in your second example

One simple way can be the use of assign() function that is pre-defined in vector class.

e.g.

array[5]={1,2,3,4,5};

vector<int> v;
v.assign(array, array+5); // 5 is size of array.

Well from your code its clear that $row['name'] is the location of the image on the file, try including the div tag like this

echo '<div>' .$row['name']. '</div>' ;

and do the same for others, let me know if it works because you said that one snippet of your code is giving the desired result so try this and if the div has some class specifier then do this

echo '<div class="whatever_it_is">' . $row['name'] . '</div'> ;

date +%Y:%m:%d|awk -vFS=":" -vOFS=":" '{$3=$3-1;print}'

You don't need jQuery for this. Here's a simple working example:

<!DOCTYPE html>
<html>
    <head>
        <title>box-shadow-experiment</title>
        <style type="text/css">
            #box-shadow-div{
                position: fixed;
                width: 1px;
                height: 1px;
                border-radius: 100%;
                background-color:black;
                box-shadow: 0 0 10px 10px black;
                top: 49%;
                left: 48.85%;
            }
        </style>
        <script type="text/javascript">
            window.onload = function(){
                var bsDiv = document.getElementById("box-shadow-div");
                var x, y;
    // On mousemove use event.clientX and event.clientY to set the location of the div to the location of the cursor:
                window.addEventListener('mousemove', function(event){
                    x = event.clientX;
                    y = event.clientY;                    
                    if ( typeof x !== 'undefined' ){
                        bsDiv.style.left = x + "px";
                        bsDiv.style.top = y + "px";
                    }
                }, false);
            }
        </script>
    </head>
    <body>
        <div id="box-shadow-div"></div>
    </body>
</html>

I chose position: fixed; so scrolling wouldn't be an issue.

To style the Toolbar on Android 21+ it's a bit different.

<style name="DarkTheme.v21" parent="DarkTheme.v19">
        <!-- toolbar background color -->
        <item name="android:navigationBarColor">@color/color_primary_blue_dark</item>
        <!-- toolbar back button color -->
        <item name="toolbarNavigationButtonStyle">@style/Toolbar.Button.Navigation.Tinted</item>
    </style>

    <style name="Toolbar.Button.Navigation.Tinted" parent="Widget.AppCompat.Toolbar.Button.Navigation">
        <item name="tint">@color/color_white</item>
    </style>

Jay Gilford's answer will work, but I think really the easiest way is to just slap a display: none; on a submit button in the form.

If someone uses AndroidStudio make sure that the assets folder is placed in

You have a problem one way or the other with your datetime.datetime.fromtimestamp(time.mktime(time.gmtime())) expression.

(1) If all you need is the difference between two instants in seconds, the very simple time.time() does the job.

(2) If you are using those timestamps for other purposes, you need to consider what you are doing, because the result has a big smell all over it:

gmtime() returns a time tuple in UTC but mktime() expects a time tuple in local time.

I'm in Melbourne, Australia where the standard TZ is UTC+10, but daylight saving is still in force until tomorrow morning so it's UTC+11. When I executed the following, it was 2011-04-02T20:31 local time here ... UTC was 2011-04-02T09:31

>>> import time, datetime
>>> t1 = time.gmtime()
>>> t2 = time.mktime(t1)
>>> t3 = datetime.datetime.fromtimestamp(t2)
>>> print t0
1301735358.78
>>> print t1
time.struct_time(tm_year=2011, tm_mon=4, tm_mday=2, tm_hour=9, tm_min=31, tm_sec=3, tm_wday=5, tm_yday=92, tm_isdst=0) ### this is UTC
>>> print t2
1301700663.0
>>> print t3
2011-04-02 10:31:03 ### this is UTC+1
>>> tt = time.time(); print tt
1301736663.88
>>> print datetime.datetime.now()
2011-04-02 20:31:03.882000 ### UTC+11, my local time
>>> print datetime.datetime(1970,1,1) + datetime.timedelta(seconds=tt)
2011-04-02 09:31:03.880000 ### UTC
>>> print time.localtime()
time.struct_time(tm_year=2011, tm_mon=4, tm_mday=2, tm_hour=20, tm_min=31, tm_sec=3, tm_wday=5, tm_yday=92, tm_isdst=1) ### UTC+11, my local time

You'll notice that t3, the result of your expression is UTC+1, which appears to be UTC + (my local DST difference) ... not very meaningful. You should consider using datetime.datetime.utcnow() which won't jump by an hour when DST goes on/off and may give you more precision than time.time()

Like this

sleep(no_of_seconds)

Or you may pass other possible arguments like:

sleep(5.seconds)

sleep(5.minutes)

sleep(5.hours)

sleep(5.days)

OutputDebugString function will do it.

example code

    void CClass::Output(const char* szFormat, ...)
{
    char szBuff[1024];
    va_list arg;
    va_start(arg, szFormat);
    _vsnprintf(szBuff, sizeof(szBuff), szFormat, arg);
    va_end(arg);

    OutputDebugString(szBuff);
}

XmlSerializer sr = new XmlSerializer(objectToSerialize.GetType());
TextWriter xmlWriter = new StreamWriter(filename);
XmlSerializerNamespaces namespaces = new XmlSerializerNamespaces();
namespaces.Add(string.Empty, string.Empty);
sr.Serialize(xmlWriter, objectToSerialize, namespaces);

Queues

Pros

• Simple messaging pattern with a transparent communication flow
• Messages can be recovered by putting them back on the queue

Cons

• Only one consumer can get the message
• Implies a coupling between producer and consumer as it’s an one-to-one relation

Topics

Pros

• Multiple consumers can get a message
• Decoupling between producer and consumers (publish-and-subscribe pattern)

Cons

• More complicated communication flow
• A message cannot be recovered for a single listener

Taken from a related post:

public static boolean isInteger(String s) {
    try { 
        Integer.parseInt(s); 
    } catch(NumberFormatException e) { 
        return false; 
    }
    // only got here if we didn't return false
    return true;
}

For Visible:

document.getElementById("test").style.visibility="visible";

For Invisible:

document.getElementById("test").style.visibility="hidden";

I have faced some problems with rel="sidebar". when I add it in link tag bookmarking will work on FF but stop working in other browser. so I fix that by adding rel="sidebar" dynamic by code:

jQuery('.bookmarkMeLink').click(function() {
    if (window.sidebar && window.sidebar.addPanel) { 
        // Mozilla Firefox Bookmark
        window.sidebar.addPanel(document.title,window.location.href,'');
    }
    else if(window.sidebar && jQuery.browser.mozilla){
        //for other version of FF add rel="sidebar" to link like this:
        //<a id="bookmarkme" href="#" rel="sidebar" title="bookmark this page">Bookmark This Page</a>
        jQuery(this).attr('rel', 'sidebar');
    }
    else if(window.external && ('AddFavorite' in window.external)) { 
        // IE Favorite
        window.external.AddFavorite(location.href,document.title); 
    } else if(window.opera && window.print) { 
        // Opera Hotlist
        this.title=document.title;
        return true;
    } else { 
        // webkit - safari/chrome
        alert('Press ' + (navigator.userAgent.toLowerCase().indexOf('mac') != - 1 ? 'Command/Cmd' : 'CTRL') + ' + D to bookmark this page.');

    }
});

AttributeError("'str' object has no attribute 'read'",)

This means exactly what it says: something tried to find a .read attribute on the object that you gave it, and you gave it an object of type str (i.e., you gave it a string).

The error occurred here:

json.load (jsonofabitch)['data']['children']

Well, you aren't looking for read anywhere, so it must happen in the json.load function that you called (as indicated by the full traceback). That is because json.load is trying to .read the thing that you gave it, but you gave it jsonofabitch, which currently names a string (which you created by calling .read on the response).

Solution: don't call .read yourself; the function will do this, and is expecting you to give it the response directly so that it can do so.

You could also have figured this out by reading the built-in Python documentation for the function (try help(json.load), or for the entire module (try help(json)), or by checking the documentation for those functions on http://docs.python.org .

We can custom A new String type via define new Type with Format support.

package main

import (
    "fmt"
    "text/template"
    "strings"
)

type String string
func (s String) Format(data map[string]interface{}) (out string, err error) {
    t := template.Must(template.New("").Parse(string(s)))
    builder := &strings.Builder{}
    if err = t.Execute(builder, data); err != nil {
        return
    }
    out = builder.String()
    return
}


func main() {
    const tmpl = `Hi {{.Name}}!  {{range $i, $r := .Roles}}{{if $i}}, {{end}}{{.}}{{end}}`
    data := map[string]interface{}{
        "Name":     "Bob",
        "Roles":    []string{"dbteam", "uiteam", "tester"},
    }

    s ,_:= String(tmpl).Format(data)
    fmt.Println(s)
}

<form id="upload_form" enctype="multipart/form-data">

jQuery with CodeIgniter file upload:

var formData = new FormData($('#upload_form')[0]);

formData.append('tax_file', $('input[type=file]')[0].files[0]);

$.ajax({
    type: "POST",
    url: base_url + "member/upload/",
    data: formData,
    //use contentType, processData for sure.
    contentType: false,
    processData: false,
    beforeSend: function() {
        $('.modal .ajax_data').prepend('<img src="' +
            base_url +
            '"asset/images/ajax-loader.gif" />');
        //$(".modal .ajax_data").html("<pre>Hold on...</pre>");
        $(".modal").modal("show");
    },
    success: function(msg) {
        $(".modal .ajax_data").html("<pre>" + msg +
            "</pre>");
        $('#close').hide();
    },
    error: function() {
        $(".modal .ajax_data").html(
            "<pre>Sorry! Couldn't process your request.</pre>"
        ); // 
        $('#done').hide();
    }
});

you can use.

var form = $('form')[0]; 
var formData = new FormData(form);     
formData.append('tax_file', $('input[type=file]')[0].files[0]);

or

var formData = new FormData($('#upload_form')[0]);
formData.append('tax_file', $('input[type=file]')[0].files[0]); 

Both will work.

You can use the CURDATE() and DATE_SUB() functions to achieve this:

SELECT URLX, COUNT(URLx) AS Count
FROM ExternalHits
WHERE datex BETWEEN DATE_SUB(CURDATE(), INTERVAL 7 DAY) AND CURDATE()    
GROUP BY URLx
ORDER BY Count DESC; 

In my case I was needed update the std=c++

I mean in my gradle file was this

android {
    ...

    defaultConfig {
        ...

        externalNativeBuild {
            cmake {
                cppFlags "-std=c++11", "-Wall"
                arguments "-DANDROID_STL=c++_static",
                        "-DARCORE_LIBPATH=${arcore_libpath}/jni",
                        "-DARCORE_INCLUDE=${project.rootDir}/app/src/main/libs"
            }
        }
       ....
    }

I changed this line

android {
    ...

    defaultConfig {
        ...

        externalNativeBuild {
            cmake {
                cppFlags "-std=c++17", "-Wall"   <-- this number from 11 to 17 (or 14)
                arguments "-DANDROID_STL=c++_static",
                        "-DARCORE_LIBPATH=${arcore_libpath}/jni",
                        "-DARCORE_INCLUDE=${project.rootDir}/app/src/main/libs"
            }
        }
       ....
    }

That's it...

...also do the conversion to upper or lower outside of the query:

tableName:= UPPER(someValue || '%');

...

Select * from table where upper(table.name) like tableName 

I'm preferred my own way to synchronize all Visual Studio Code extensions between laptops, using .dotfiles and small script to perform updates automatically. This way helps me every time when I want to install all extensions I have without any single mouse activity in Visual Studio Code after installing (via Homebrew).

So I just write each new added extension to .txt file stored at my .dotfiles folder. After that I pull master branch on another laptop to get up-to-date file with all extensions.

Using the script, which Big Rich had written before, with one more change, I can totally synchronise all extensions almost automatically.

Script

cat dart-extensions.txt | xargs -L 1 code --install-extension

And also there is one more way to automate that process. Here you can add a script which looks up a Visual Studio Code extension in realtime and each time when you take a diff between the code --list-extensions command and your .txt file in .dotfiles, you can easily update your file and push it to your remote repository.

A method for future reference is something like this. bannedphraseform is the first form and expectedphraseform is the second. If the first one is hit, the second one is skipped (which is a reasonable assumption in this case):

if request.method == 'POST':
    bannedphraseform = BannedPhraseForm(request.POST, prefix='banned')
    if bannedphraseform.is_valid():
        bannedphraseform.save()
else:
    bannedphraseform = BannedPhraseForm(prefix='banned')

if request.method == 'POST' and not bannedphraseform.is_valid():
    expectedphraseform = ExpectedPhraseForm(request.POST, prefix='expected')
    bannedphraseform = BannedPhraseForm(prefix='banned')
    if expectedphraseform.is_valid():
        expectedphraseform.save()

else:
    expectedphraseform = ExpectedPhraseForm(prefix='expected')

There isn't any direct equivalent to the goto concept in Java. There are a few constructs that allow you to do some of the things you can do with a classic goto.

• The break and continue statements allow you to jump out of a block in a loop or switch statement.
• A labeled statement and break <label> allow you to jump out of an arbitrary compound statement to any level within a given method (or initializer block).
• If you label a loop statement, you can continue <label> to continue with the next iteration of an outer loop from an inner loop.
• Throwing and catching exceptions allows you to (effectively) jump out of many levels of a method call. (However, exceptions are relatively expensive and are considered to be a bad way to do "ordinary" control flow¹.)
• And of course, there is return.

None of these Java constructs allow you to branch backwards or to a point in the code at the same level of nesting as the current statement. They all jump out one or more nesting (scope) levels and they all (apart from continue) jump downwards. This restriction helps to avoid the goto "spaghetti code" syndrome inherent in old BASIC, FORTRAN and COBOL code².

^{1- The most expensive part of exceptions is the actual creation of the exception object and its stacktrace. If you really, really need to use exception handling for "normal" flow control, you can either preallocate / reuse the exception object, or create a custom exception class that overrides the fillInStackTrace() method. The downside is that the exception's printStackTrace() methods won't give you useful information ... should you ever need to call them.}

^{2 - The spaghetti code syndrome spawned the structured programming approach, where you limited in your use of the available language constructs. This could be applied to BASIC, Fortran and COBOL, but it required care and discipline. Getting rid of goto entirely was a pragmatically better solution. If you keep it in a language, there is always some clown who will abuse it.}

Since I recommended printf in a comment, I should probably give some examples of its usage (although for printing a usage message, I'd be more likely to use Dennis' or Chris' answers). printf is a bit more complex to use than echo. Its first argument is a format string, in which escapes (like \n) are always interpreted; it can also contain format directives starting with %, which control where and how any additional arguments are included in it. Here are two different approaches to using it for a usage message:

First, you could include the entire message in the format string:

printf "usage: up [--level <n>| -n <levels>][--help][--version]\n\nReport bugs to: \nup home page: \n"

Note that unlike echo, you must include the final newline explicitly. Also, if the message happens to contain any % characters, they would have to be written as %%. If you wanted to include the bugreport and homepage addresses, they can be added quite naturally:

printf "usage: up [--level <n>| -n <levels>][--help][--version]\n\nReport bugs to: %s\nup home page: %s\n" "$bugreport" "$homepage"

Second, you could just use the format string to make it print each additional argument on a separate line:

printf "%s\n" "usage: up [--level <n>| -n <levels>][--help][--version]" "" "Report bugs to: " "up home page: "

With this option, adding the bugreport and homepage addresses is fairly obvious:

printf "%s\n" "usage: up [--level <n>| -n <levels>][--help][--version]" "" "Report bugs to: $bugreport" "up home page: $homepage"

I tried joonty's answer, but I also got the

exec: 1: not found

error. This is what works best for me (confirmed to work in zsh also):

#!/bin/bash
LOG_FILE=/tmp/both.log
exec > >(tee ${LOG_FILE}) 2>&1
echo "this is stdout"
chmmm 77 /makeError

The file /tmp/both.log afterwards contains

this is stdout
chmmm command not found 

The /tmp/both.log is appended unless you remove the -a from tee.

Hint: >(...) is a process substitution. It lets the exec to the tee command as if it were a file.

I think Asa's answer is essentially correct, but you could extend it a little to act more like mkdir -p, either:

import os

def mkdir_path(path):
    if not os.access(path, os.F_OK):
        os.mkdirs(path)

or

import os
import errno

def mkdir_path(path):
    try:
        os.mkdirs(path)
    except os.error, e:
        if e.errno != errno.EEXIST:
            raise

These both handle the case where the path already exists silently but let other errors bubble up.

Set proper constraint and update delegate methods as:

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return UITableViewAutomaticDimension
}
func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
    return UITableViewAutomaticDimension
}

This will resolve dynamic cell height issue. IF not you need to check constraints.

You can use pd.DataFrame.mask with np.isinf. You should ensure first your dataframe series are all of type float. Then use dropna with your existing logic.

print(df)

       col1      col2
0 -0.441406       inf
1 -0.321105      -inf
2 -0.412857  2.223047
3 -0.356610  2.513048

df = df.mask(np.isinf(df))

print(df)

       col1      col2
0 -0.441406       NaN
1 -0.321105       NaN
2 -0.412857  2.223047
3 -0.356610  2.513048

Give them a trivial pom with these jars listed as dependencies and instructions to run:

mvn dependency:go-offline

This will pull the dependencies to the local repo.

A more direct solution is dependency:get, but it's a lot of arguments to type:

mvn dependency:get -DrepoUrl=something -Dartifact=group:artifact:version

One more way for square matrix. No numpy, nor itertools, use (effective) in-place elements exchange.

def transpose(m):
    for i in range(1, len(m)):
        for j in range(i):
            m[i][j], m[j][i] = m[j][i], m[i][j]

I am using Windows and get the same error message. I find another problem which is relevant. I defined OpenCV_DIR in my path at the end of the line. However when I typed "path" in the command line, my OpenCV_DIR was not shown. I found because Windows probably has a limit on how long the path can be, it cut my OpenCV_DIR to be only part of what I defined. So I removed some other part of the path, now it works.

Here's a start. Basically, we copy the header on load, and then check (using .scrollTop() or window.scrollY) to see when the user scrolls beyond a point (e.g. 200pixels). Then we simply toggle a class (in this case .down) which moves the original into view.

Lastly all we need to do is apply a transition: top 0.2s ease-in to our clone, so that when it's in the .down state it slides into view. Dunked does it better, but with a little playing around it's easy to configure

CSS

header {
  position: relative;
  width: 100%;
  height: 60px;
}

header.clone {
  position: fixed;
  top: -65px;
  left: 0;
  right: 0;
  z-index: 999;
  transition: 0.2s top cubic-bezier(.3,.73,.3,.74);
}

body.down header.clone {
  top: 0;
}

either Vanilla JS (polyfill as required)

var sticky = {
  sticky_after: 200,
  init: function() {
    this.header = document.getElementsByTagName("header")[0];
    this.clone = this.header.cloneNode(true);
    this.clone.classList.add("clone");
    this.header.insertBefore(this.clone);
    this.scroll();
    this.events();
  },

  scroll: function() {
    if(window.scrollY > this.sticky_after) {
      document.body.classList.add("down");
    }
    else {
      document.body.classList.remove("down");
    }
  },

  events: function() {
    window.addEventListener("scroll", this.scroll.bind(this));
  }
};

document.addEventListener("DOMContentLoaded", sticky.init.bind(sticky));

or jQuery

$(document).ready(function() {
  var $header = $("header"),
      $clone = $header.before($header.clone().addClass("clone"));

  $(window).on("scroll", function() {
    var fromTop = $("body").scrollTop();
    $('body').toggleClass("down", (fromTop > 200));
  });
});

Newer Reflections

Whilst the above answers the OP's original question of "How does Dunked achieve this effect?", I wouldn't recommend this approach. For starters, copying the entire top navigation could be pretty costly, and there's no real reason why we can't use the original (with a little bit of work).

Furthermore, Paul Irish and others, have written about how animating with translate() is better than animating with top. Not only is it more performant, but it also means that you don't need to know the exact height of your element. The above solution would be modified with the following (See JSFiddle):

header.clone {
  position: fixed;
  top: 0;
  left: 0;
  right: 0;
  transform: translateY(-100%);
  transition: 0.2s transform cubic-bezier(.3,.73,.3,.74);
}

body.down header.clone {
  transform: translateY(0);
}

The only drawback with using transforms is, that whilst browser support is pretty good, you'll probably want to add vendor prefixed versions to maximize compatibility.

I know this is an old one, but I wanted to post a variation of the accepted answer that will work in IE without removing lines:

function multiLineHtmlEncode(value) {
    var lines = value.split(/\r\n|\r|\n/);
    for (var i = 0; i < lines.length; i++) {
        lines[i] = htmlEncode(lines[i]);
    }
    return lines.join('\r\n');
}

function htmlEncode(value) {
    return $('<div/>').text(value).html();
} 

SELECT account_id, open_emp_id
         ^^^^        ^^^^
          1           2

FROM account
GROUP BY 1;

In above query GROUP BY 1 refers to the first column in select statement which is account_id.

You also can specify in ORDER BY.

Note : The number in ORDER BY and GROUP BY always start with 1 not with 0.

Setting an Initial Catalog allows you to set the database that queries run on that connection will use by default. If you do not set this for a connection to a server in which multiple databases are present, in many cases you will be required to have a USE statement in every query in order to explicitly declare which database you are trying to run the query on. The Initial Catalog setting is a good way of explicitly declaring a default database.

You can try to set the proxy settings:

File -> Settings -> Appearance -> System Settings -> Http proxy -> Auto Detect

And then provide the proxy URL.

The InterruptedException is usually thrown when a sleep is interrupted.

I had the same problem, but believe it or not is was a case of case sensitivity.

This on localhost: http://localhost/.../getdata.php?id=3

Did not behave the same as this on the server: http://server/.../getdata.php?id=3

Changing the server url to this (notice the capital D in getData) solved my issue. http://localhost/.../getData.php?id=3

I wrote an unzipper in Javascript. It works.

It relies on Andy G.P. Na's binary file reader and some RFC1951 inflate logic from notmasteryet. I added the ZipFile class.

working example:
http://cheeso.members.winisp.net/Unzip-Example.htm (dead link)

The source:
http://cheeso.members.winisp.net/srcview.aspx?dir=js-unzip (dead link)

NB: the links are dead; I'll find a new host soon.

Included in the source is a ZipFile.htm demonstration page, and 3 distinct scripts, one for the zipfile class, one for the inflate class, and one for a binary file reader class. The demo also depends on jQuery and jQuery UI. If you just download the js-zip.zip file, all of the necessary source is there.

Here's what the application code looks like in Javascript:

// In my demo, this gets attached to a click event.
// it instantiates a ZipFile, and provides a callback that is
// invoked when the zip is read.  This can take a few seconds on a
// large zip file, so it's asynchronous. 
var readFile = function(){
    $("#status").html("<br/>");
    var url= $("#urlToLoad").val();
    var doneReading = function(zip){
        extractEntries(zip);
    };

    var zipFile = new ZipFile(url, doneReading);
};


// this function extracts the entries from an instantiated zip
function extractEntries(zip){
    $('#report').accordion('destroy');

    // clear
    $("#report").html('');

    var extractCb = function(id) {
        // this callback is invoked with the entry name, and entry text
        // in my demo, the text is just injected into an accordion panel.
        return (function(entryName, entryText){
            var content = entryText.replace(new RegExp( "\\n", "g" ), "<br/>");
            $("#"+id).html(content);
            $("#status").append("extract cb, entry(" + entryName + ")  id(" + id + ")<br/>");
            $('#report').accordion('destroy');
            $('#report').accordion({collapsible:true, active:false});
        });
    }

    // for each entry in the zip, extract it. 
    for (var i=0; i<zip.entries.length;  i++) {
        var entry = zip.entries[i];

        var entryInfo = "<h4><a>" + entry.name + "</a></h4>\n<div>";

        // contrive an id for the entry, make it unique
        var randomId = "id-"+ Math.floor((Math.random() * 1000000000));

        entryInfo += "<span class='inputDiv'><h4>Content:</h4><span id='" + randomId +
            "'></span></span></div>\n";

        // insert the info for one entry as the last child within the report div
        $("#report").append(entryInfo);

        // extract asynchronously
        entry.extract(extractCb(randomId));
    }
}

The demo works in a couple of steps: The readFile fn is triggered by a click, and instantiates a ZipFile object, which reads the zip file. There's an asynchronous callback for when the read completes (usually happens in less than a second for reasonably sized zips) - in this demo the callback is held in the doneReading local variable, which simply calls extractEntries, which just blindly unzips all the content of the provided zip file. In a real app you would probably choose some of the entries to extract (allow the user to select, or choose one or more entries programmatically, etc).

The extractEntries fn iterates over all entries, and calls extract() on each one, passing a callback. Decompression of an entry takes time, maybe 1s or more for each entry in the zipfile, which means asynchrony is appropriate. The extract callback simply adds the extracted content to an jQuery accordion on the page. If the content is binary, then it gets formatted as such (not shown).

It works, but I think that the utility is somewhat limited.

For one thing: It's very slow. Takes ~4 seconds to unzip the 140k AppNote.txt file from PKWare. The same uncompress can be done in less than .5s in a .NET program. EDIT: The Javascript ZipFile unpacks considerably faster than this now, in IE9 and in Chrome. It is still slower than a compiled program, but it is plenty fast for normal browser usage.

For another: it does not do streaming. It basically slurps in the entire contents of the zipfile into memory. In a "real" programming environment you could read in only the metadata of a zip file (say, 64 bytes per entry) and then read and decompress the other data as desired. There's no way to do IO like that in javascript, as far as I know, therefore the only option is to read the entire zip into memory and do random access in it. This means it will place unreasonable demands on system memory for large zip files. Not so much a problem for a smaller zip file.

Also: It doesn't handle the "general case" zip file - there are lots of zip options that I didn't bother to implement in the unzipper - like ZIP encryption, WinZip encryption, zip64, UTF-8 encoded filenames, and so on. (EDIT - it handles UTF-8 encoded filenames now). The ZipFile class handles the basics, though. Some of these things would not be hard to implement. I have an AES encryption class in Javascript; that could be integrated to support encryption. Supporting Zip64 would probably useless for most users of Javascript, as it is intended to support >4gb zipfiles - don't need to extract those in a browser.

I also did not test the case for unzipping binary content. Right now it unzips text. If you have a zipped binary file, you'd need to edit the ZipFile class to handle it properly. I didn't figure out how to do that cleanly. It does binary files now, too.

EDIT - I updated the JS unzip library and demo. It now does binary files, in addition to text. I've made it more resilient and more general - you can now specify the encoding to use when reading text files. Also the demo is expanded - it shows unzipping an XLSX file in the browser, among other things.

So, while I think it is of limited utility and interest, it works. I guess it would work in Node.js.

Use double [] when writing your vectors.

Then, if you want a row vector:

row_vector = array([[1, 2, 3]])    # shape (1, 3)

Or if you want a column vector:

col_vector = array([[1, 2, 3]]).T  # shape (3, 1)

By default Elasticsearch return 10 records so size should be provided explicitly.

Add size with request to get desire number of records.

http://{host}:9200/{index_name}/_search?pretty=true&size=(number of records)

Note : Max page size can not be more than index.max_result_window index setting which defaults to 10,000.

The following works without flattening the folder structure:

gulp.src(['input/folder/**/*']).pipe(gulp.dest('output/folder'));

The '**/*' is the important part. That expression is a glob which is a powerful file selection tool. For example, for copying only .js files use: 'input/folder/**/*.js'

Following solution also provide array of subset which provide specific sum (here sum = 9)

array = [1, 3, 4, 2, 7, 8, 9]

(0..array.size).map { |i| array.combination(i).to_a.select { |a| a.sum == 9 } }.flatten(1)

return array of subsets which return sum of 9

 => [[9], [1, 8], [2, 7], [3, 4, 2]] 

Its pretty simple you use the sort function from algorithm and add your own compare function

vector< pair<int,int > > v;
sort(v.begin(),v.end(),myComparison);

Now you have to make the comparison based on the second selection so declare you "myComparison" as

bool myComparison(const pair<int,int> &a,const pair<int,int> &b)
{
       return a.second<b.second;
}

Since you know how many pixels are occupied by the previous content, you can use the calc() function:

height: calc(100% - 50px);

Pass in the straight XML instead of a dictionary.

Best is

date -r filename +"%Y-%m-%d %H:%M:%S"

In Java:

public boolean containsNumber(String string)
{
    return string.matches(".*\\d+.*");
}  

Why does TypeError: 'list' object is not callable appear?

Explanation:

It is because you defined list as a variable before (i am pretty sure), so it would be a list, not the function anymore, that's why everyone shouldn't name variables functions, the below is the same as what you're doing now:

>>> [1,2,3]()
Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    [1,2,3]()
TypeError: 'list' object is not callable
>>>  

So you need it to be the default function of list, how to detect if it is? just use:

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

How do i detect whether a variable name is a function? well, just simple see if it has a different color, or use a code like:

>>> 'list' in dir(__builtins__)
True
>>> 'blah' in dir(__builtins__)
False
>>> 

After this, you should know why does TypeError: 'list' object is not callable appear.

Okay, so now...

How to fix this TypeError: 'list' object is not callable error?

Code:

You have to either do __builtins__.list():

>>> list = [1,2,3]
>>> __builtins__.list()
[]
>>> 

Or use []:

>>> list = [1,2,3]
>>> []
[]
>>> 

Or remove list variable from memory:

>>> list = [1,2,3]
>>> del list
>>> list()
[]
>>> 

Or just rename the variable:

>>> lst = [1,2,3]
>>> list()
[]
>>> 

P.S. Last one is the most preferable i guess :-)

There are a whole bunch of solutions that work.

This is not the exact answer to this question, but those who are not able to find setting popup. Their is two ways to open setting pop up.

Note: I had problem on Windows 7 but it might help you as well..

I had problem with android studio detecting my phone(Acer Liquid Zest 4G), tried restarting android studio, switching back and forth between PTP and MTP, OS was able to detect device normally.

So what I did was, in Developer Options i enabled USB debugging, USB connection is in PTP mode, then from phone manufacturer's site (you can find site for your phone here: https://developer.android.com/studio/run/oem-usb.html), I downloaded USB driver for my phone model, installed driver and android studio was able to detect my phone(there was no need for restart).

I will repeat again, you must have USB Debugging enabled in Developer Options, otherwise it won't work. Hope it helps.

In my case when I had this problem. I had a local file that I had renamed on the remote.

When trying to git pull Git told me the new filename was not tracked -- which it was on the remote although it didn't yet exist on local.

Because there was no instance of it locally I couldn't do git pull until I did git rm on the old filename (which wasn't obvious at first because of my stupid idea of renaming it).

updateValue(data){    
     // retriving index from array
     let indexValue = this.items.indexOf(data);
    // changing specific element in array
     this.items[indexValue].isShow =  !this.items[indexValue].isShow;
}

I think the current answers are neglecting to highlight the actual important and significant differences and what that means for the intended usage. While they might both work in certain situations because the implementer built in support for both, they have different usage scenarios. Both can annotate properties and methods but here are some important differences:

DisplayAttribute

• defined in the System.ComponentModel.DataAnnotations namespace in the System.ComponentModel.DataAnnotations.dll assembly
• can be used on parameters and fields
• lets you set additional properties like Description or ShortName
• can be localized with resources

DisplayNameAttribute

• DisplayName is in the System.ComponentModel namespace in System.dll
• can be used on classes and events
• cannot be localized with resources

The assembly and namespace speaks to the intended usage and localization support is the big kicker. DisplayNameAttribute has been around since .NET 2 and seems to have been intended more for naming of developer components and properties in the legacy property grid, not so much for things visible to end users that may need localization and such.

DisplayAttribute was introduced later in .NET 4 and seems to be designed specifically for labeling members of data classes that will be end-user visible, so it is more suitable for DTOs, entities, and other things of that sort. I find it rather unfortunate that they limited it so it can't be used on classes though.

EDIT: Looks like latest .NET Core source allows DisplayAttribute to be used on classes now as well.

IMHO, the most convenient way is to follow "Import CSV data into postgresql, the comfortable way ;-)", using csvsql from csvkit, which is a python package installable via pip.

The simplest way to add color programmatically is by using ColorLiteral.

Just add the property ColorLiteral as shown in the example, Xcode will prompt you with a whole list of colors which you can choose. The advantage of doing so is lesser code, add HEX values or RGB. You will also get the recently used colors from the storyboard.

Example: self.view.backgroundColor = ColorLiteral

Try this:

jQuery(document).ready(function(){
   $("#special").click(function(e){
      $('#status2').html(e.pageX +', '+ e.pageY);
   }); 
})

If your matrix is given in row manner like below, where size is s*s here s=5 5 31 100 65 12 18 10 13 47 157 6 100 113 174 11 33 88 124 41 20 140 99 32 111 41 20

then you can use this

s=int(input())
b=list(map(int,input().split()))
arr=[[b[j+s*i] for j in range(s)]for i in range(s)]

your matrix will be 'arr'

A wrapper like this would work:

public class ServiceClientWrapper<ServiceType> : IDisposable
{
    private ServiceType _channel;
    public ServiceType Channel
    {
        get { return _channel; }
    }

    private static ChannelFactory<ServiceType> _channelFactory;

    public ServiceClientWrapper()
    {
        if(_channelFactory == null)
             // Given that the endpoint name is the same as FullName of contract.
            _channelFactory = new ChannelFactory<ServiceType>(typeof(T).FullName);
        _channel = _channelFactory.CreateChannel();
        ((IChannel)_channel).Open();
    }

    public void Dispose()
    {
        try
        {
            ((IChannel)_channel).Close();
        }
        catch (Exception e)
        {
            ((IChannel)_channel).Abort();
            // TODO: Insert logging
        }
    }
}

That should enable you to write code like:

ResponseType response = null;
using(var clientWrapper = new ServiceClientWrapper<IService>())
{
    var request = ...
    response = clientWrapper.Channel.MyServiceCall(request);
}
// Use your response object.

The wrapper could of course catch more exceptions if that is required, but the principle remains the same.

Since you have not mentioned what needs to be copied, I have left that section empty in the code below.

Also you don't need to move the email to the folder first and then run the macro in that folder. You can run the macro on the incoming mail and then move it to the folder at the same time.

This will get you started. I have commented the code so that you will not face any problem understanding it.

First paste the below mentioned code in the outlook module.

Then

1. Click on Tools~~>Rules and Alerts
2. Click on "New Rule"
3. Click on "start from a blank rule"
4. Select "Check messages When they arrive"
5. Under conditions, click on "with specific words in the subject"
6. Click on "specific words" under rules description.
7. Type the word that you want to check in the dialog box that pops up and click on "add".
8. Click "Ok" and click next
9. Select "move it to specified folder" and also select "run a script" in the same box
10. In the box below, specify the specific folder and also the script (the macro that you have in module) to run.
11. Click on finish and you are done.

When the new email arrives not only will the email move to the folder that you specify but data from it will be exported to Excel as well.

MyAr = Split(olMail.body, vbCrLf)

For i = LBound(MyAr) To UBound(MyAr)
    '~~> This will give you the contents of your email
    '~~> on separate lines
    Debug.Print MyAr(i)
Next i

It's a linker error. ld is the linker, so if you get an error message ending with "ld returned 1 exit status", that tells you that it's a linker error.

The error message tells you that none of the object files you're linking against contains a definition for avergecolumns. The reason for that is that the function you've defined is called averagecolumns (in other words: you misspelled the function name when calling the function (and presumably in the header file as well - otherwise you'd have gotten a different error at compile time)).

With PHP I'm doing:

<a href="?action=logout">logout.</a>

if(isset($_GET['action']) && $_GET['action'] === 'logout'){
    $facebook->destroySession();
    header(WHERE YOU WANT TO REDIRECT TO);
    exit();
}

Works and is nice and easy am just trying to find a logout button graphic now!

the following code works for me in this scenario: an UIImageView forced landscape.

    imagePreview!.isUserInteractionEnabled = true
    imagePreview!.isExclusiveTouch = true
    imagePreview!.contentMode = UIView.ContentMode.scaleAspectFit
    
    // Remove all constraints
    imagePreview!.removeAllConstraints()
    
    // Add the new constraints
    let guide = view.safeAreaLayoutGuide
    imagePreview!.translatesAutoresizingMaskIntoConstraints = false
    imagePreview!.leadingAnchor.constraint(equalTo: guide.leadingAnchor).isActive = true
    imagePreview!.trailingAnchor.constraint(equalTo: guide.trailingAnchor).isActive = true
    imagePreview!.heightAnchor.constraint(equalTo: guide.heightAnchor, multiplier: 1.0).isActive = true

where removeAllConstraints is an extension

extension UIView {
    
    func removeAllConstraints() {
        var _superview = self.superview
        
        func removeAllConstraintsFromView(view: UIView) { for c in view.constraints { view.removeConstraint(c) } }
        
        while let superview = _superview {
            for constraint in superview.constraints {
                
                if let first = constraint.firstItem as? UIView, first == self {
                    superview.removeConstraint(constraint)
                }
                
                if let second = constraint.secondItem as? UIView, second == self {
                    superview.removeConstraint(constraint)
                }
            }
            
            _superview = superview.superview
        }
        
        self.removeConstraints(self.constraints)
        self.translatesAutoresizingMaskIntoConstraints = true
    }
}

The above answers don't really answer this aspect of the original question: What is a lifecycle hook? It took me a while to understand what that means until I thought of it this way.

1) Say your component is a human. Humans have lives that include many stages of living, and then we expire.

2) Our human component could have the following lifecycle script: Born, Baby, Grade School, Young Adult, Mid-age Adult, Senior Adult, Dead, Disposed of.

3) Say you want to have a function to create children. To keep this from getting complicated, and rather humorous, you want your function to only be called during the Young Adult stage of the human component life. So you develop a component that is only active when the parent component is in the Young Adult stage. Hooks help you do that by signaling that stage of life and letting your component act on it.

Fun stuff. If you let your imagination go to actually coding something like this it gets complicated, and funny.

If you have a flash FLA file that shows the FLV movie you can add a button inside the FLA file. This button can be given an action to load the URL.

on (release) {
  getURL("http://someurl/");
}

To make the button transparent you can place a square inside it that is moved to the hit-area frame of the button.

I think it would go too far to explain into depth with pictures how to go about in stackoverflow.

jQuery needs to be the first script you import. The first script on your page

<script type="text/javascript" src="/test/wp-content/themes/child/script/jquery.jcarousel.min.js"></script>

appears to be a jQuery plugin, which is likely generating an error since jQuery hasn't been loaded on the page yet.

The fastest way is to do a*a or a**2 or np.square(a) whereas np.power(a, 2) showed to be considerably slower.

np.power() allows you to use different exponents for each element if instead of 2 you pass another array of exponents. From the comments of @GarethRees I just learned that this function will give you different results than a**2 or a*a, which become important in cases where you have small tolerances.

I've timed some examples using NumPy 1.9.0 MKL 64 bit, and the results are shown below:

In [29]: a = np.random.random((1000, 1000))

In [30]: timeit a*a
100 loops, best of 3: 2.78 ms per loop

In [31]: timeit a**2
100 loops, best of 3: 2.77 ms per loop

In [32]: timeit np.power(a, 2)
10 loops, best of 3: 71.3 ms per loop

You need to use CreateProcess [ http://msdn.microsoft.com/en-us/library/windows/desktop/ms682425(v=vs.85).aspx ]

For ex:

LPTSTR szCmdline[] = _tcsdup(TEXT("\"C:\Program Files\MyApp\" -L -S")); CreateProcess(NULL, szCmdline, /.../);

As you say, hidden-xs is not enough, you have to combine xs and sm class.

Here is links to the official doc about available responsive classes and about the grid system.

• For XtraSmall device : col-xs-__
  
• For SMall device : col-sm-__
  
• For MeDium Device: col-md-__
  
• For LarGe Device : col-lg-__
  
• Make visible only (hidden on other) : visible-md (just visible in medium [not in lg xs or sm])
• Make hidden only (visible on other) : hidden-xs (just hidden in XtraSmall)

I created a custom view that is at 100%. Use the dropdowns then click to view page layout to go back to a smaller view.

TL;DR:

• If your input is mostly strings that can be converted to floats, the try: except: method is the best native Python method.
• If your input is mostly strings that cannot be converted to floats, regular expressions or the partition method will be better.
• If you are 1) unsure of your input or need more speed and 2) don't mind and can install a third-party C-extension, fastnumbers works very well.

There is another method available via a third-party module called fastnumbers (disclosure, I am the author); it provides a function called isfloat. I have taken the unittest example outlined by Jacob Gabrielson in this answer, but added the fastnumbers.isfloat method. I should also note that Jacob's example did not do justice to the regex option because most of the time in that example was spent in global lookups because of the dot operator... I have modified that function to give a fairer comparison to try: except:.

def is_float_try(str):
    try:
        float(str)
        return True
    except ValueError:
        return False

import re
_float_regexp = re.compile(r"^[-+]?(?:\b[0-9]+(?:\.[0-9]*)?|\.[0-9]+\b)(?:[eE][-+]?[0-9]+\b)?$").match
def is_float_re(str):
    return True if _float_regexp(str) else False

def is_float_partition(element):
    partition=element.partition('.')
    if (partition[0].isdigit() and partition[1]=='.' and partition[2].isdigit()) or (partition[0]=='' and partition[1]=='.' and partition[2].isdigit()) or (partition[0].isdigit() and partition[1]=='.' and partition[2]==''):
        return True
    else:
        return False

from fastnumbers import isfloat

As you can see, regex is actually not as bad as it originally seemed, and if you have a real need for speed, the fastnumbers method is quite good.

Looks like you might have until the end of 2013 before they officially close it down. http://groups.google.com/group/google-ajax-search-api/browse_thread/thread/6aaa1b3529620610/d70f8eec3684e431?lnk=gst&q=news+api#d70f8eec3684e431

Also, it sounds like they are building a replacement... but it's going to cost you.

I'd say, go to a different service. I think bing has a news API.

This isn't strictly an answer to your question about installing .gem packages, but you can specify all kinds of locations on a gem-by-gem basis by editing your Gemfile.

Specifying a :path attribute will install the gem from that path on your local machine.

gem "foreman", path: "/Users/pje/my_foreman_fork"

Alternately, specifying a :git attribute will install the gem from a remote git repository.

gem "foreman", git: "git://github.com/pje/foreman.git"

# ...or at a specific SHA-1 ref
gem "foreman", git: "git://github.com/pje/foreman.git", ref: "bf648a070c"

# ...or branch
gem "foreman", git: "git://github.com/pje/foreman.git", branch: "jruby"

# ...or tag
gem "foreman", git: "git://github.com/pje/foreman.git", tag: "v0.45.0"

Finally got the answer for datepicker date change method:

$('#formatdate').change(function(){
    $('#datpicker').datepicker("option","dateFormat","yy-mm-dd");
});

:last-child will not work if the element is not the VERY LAST element

In addition to Harry's answer, I think it's crucial to add/emphasize that :last-child will not work if the element is not the VERY LAST element in a container. For whatever reason it took me hours to realize that, and even though Harry's answer is very thorough I couldn't extract that information from "The last-child selector is used to select the last child element of a parent."

Suppose this is my selector: a:last-child {}

This works:

<div>
    <a></a>
    <a>This will be selected</a>
</div>

This doesn't:

<div>
    <a></a>
    <a>This will no longer be selected</a>
    <div>This is now the last child :'( </div>
</div>

It doesn't because the a element is not the last element inside its parent.

It may be obvious, but it was not for me...

Listen to window:scroll event for window/document level scrolling and element's scroll event for element level scrolling.

window:scroll

@HostListener('window:scroll', ['$event'])
onWindowScroll($event) {

}

or

<div (window:scroll)="onWindowScroll($event)">

scroll

@HostListener('scroll', ['$event'])
onElementScroll($event) {

}

or

<div (scroll)="onElementScroll($event)">

@HostListener('scroll', ['$event']) won't work if the host element itself is not scroll-able.

Examples

• Using Event Binding
• Using HostListener

I also had this error when I was working in a Java class once. My problem was simply that my xml file, with the references in it, was not saved. If you have both the xml file and java class open in tabs, check to make sure the xml file name in the tab doesn't have a * by it.

Hope this helps.

I took a different approach:

Background: I use mongodb, single node, local to my server, as a staging area.

I installed mongo based on instructions available in MongoDB docs.

So, this is not 'prime' infrastructure, does not need to be up all the time - but still essential.

What I do: In my run script, I check if mongo is running using -

if pgrep "mongod" >/dev/null 2>&1

If it is not running, then I run

sudo mongod &

Been working like a charm, no setup etc.

If your use case is similar, let me know if it works for you too.

Good luck!

Yes. Pass gcc the -E option. This will output preprocessed source code.

found it on this site, it works on me. Modify /res/values/styles.xml from:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
</style>

to:

<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
</style>

Basically it allows Java to store several types of objects in one structure implementation, by generic type declaration (like class MyStructure<T extends TT>), which is one of Javas main features.

Object-oriented approaches are based in modularity and reusability by separation of concerns - the ability to use a structure with any kind of types of object (as long as it obeys a few rules).

You could just instantiate things as followed:

ArrayList list = new ArrayList();

instead of

ArrayList<String> list = new ArrayList<>();

By declaring and using generic types you are informing a structure of the kind of objects it will manage and the compiler will be able to inform you if you're inserting an illegal type into that structure, for instance. Let's say:

// this works
List list1 = new ArrayList();
list1.add(1);
list1.add("one");

// does not work
List<String> list2 = new ArrayList<>();
list2.add(1); // compiler error here
list2.add("one");

If you want to see some examples check the documentation documentation:

/**
 * Generic version of the Box class.
 * @param <T> the type of the value being boxed
 */
public class Box<T> {
    // T stands for "Type"
    private T t;

    public void set(T t) { this.t = t; }
    public T get() { return t; }
}

Then you could instantiate things like:

class Paper  { ... }
class Tissue { ... }

// ...
Box<Paper> boxOfPaper = new Box<>();
boxOfPaper.set(new Paper(...));

Box<Tissue> boxOfTissues = new Box<>();
boxOfTissues.set(new Tissue(...));

The main thing to draw from this is you're specifying which type of object you want to box.

As for using Object l = new ArrayList<>();, you're not accessing the List or ArrayList implementation so you won't be able to do much with the collection.

Iterate through the list and check if contains your string "How" and if it does then remove. You can use following code:

// need to construct a new ArrayList otherwise remove operation will not be supported
List<String> list = new ArrayList<String>(Arrays.asList(new String[] 
                                  {"How are you?", "How you doing?","Joe", "Mike"}));
System.out.println("List Before: " + list);
for (Iterator<String> it=list.iterator(); it.hasNext();) {
    if (!it.next().contains("How"))
        it.remove(); // NOTE: Iterator's remove method, not ArrayList's, is used.
}
System.out.println("List After: " + list);

OUTPUT:

List Before: [How are you?, How you doing?, Joe, Mike]
List After: [How are you?, How you doing?]

A more verbose, but broadly applicable solution to this sort of problem is to use a pair of data structures: a list to contain the ordering, and a map to contain the relations.

For Example:

{
    "items":
    [
        {
            "WR":"qwe",
            "QU":"asd",
            "QA":"end",
            "WO":"hasd",
            "NO":"qwer"
        },
    ],
    "itemOrder":
        ["WR", "QU", "QA", "WO", "NO"]
}

You iterate the itemOrder list, and use those to look up the map values. Ordering is preserved, with no kludges.

I have used this method many times.

If matching a sequence of characters is not sufficient and you need to match whole words, here is a simple function that gets the job done. It basically appends spaces where necessary and searches for that in the string:

def smart_find(haystack, needle):
    if haystack.startswith(needle+" "):
        return True
    if haystack.endswith(" "+needle):
        return True
    if haystack.find(" "+needle+" ") != -1:
        return True
    return False

This assumes that commas and other punctuations have already been stripped out.

Simply:

String abc="abcdefghight";

byte[] b = abc.getBytes();

Here are three ways to parse strings into integers, from fastest runtime to slowest:

1. strconv.ParseInt(...) fastest
2. strconv.Atoi(...) still very fast
3. fmt.Sscanf(...) not terribly fast but most flexible

Here's a benchmark that shows usage and example timing for each function:

package main

import "fmt"
import "strconv"
import "testing"

var num = 123456
var numstr = "123456"

func BenchmarkStrconvParseInt(b *testing.B) {
  num64 := int64(num)
  for i := 0; i < b.N; i++ {
    x, err := strconv.ParseInt(numstr, 10, 64)
    if x != num64 || err != nil {
      b.Error(err)
    }
  }
}

func BenchmarkAtoi(b *testing.B) {
  for i := 0; i < b.N; i++ {
    x, err := strconv.Atoi(numstr)
    if x != num || err != nil {
      b.Error(err)
    }
  }
}

func BenchmarkFmtSscan(b *testing.B) {
  for i := 0; i < b.N; i++ {
    var x int
    n, err := fmt.Sscanf(numstr, "%d", &x)
    if n != 1 || x != num || err != nil {
      b.Error(err)
    }
  }
}

You can run it by saving as atoi_test.go and running go test -bench=. atoi_test.go.

i had a similar problem - firefox returned the correct value of obj.clientHeight but ie did not- it returned 0. I changed it to obj.offsetHeight and it worked. Seems there is some state that ie has for clientheight - that makes it iffy...

Yes, underscores may be used anywhere in an identifier. I believe the rules are: any of a-z, A-Z, _ in the first character and those +0-9 for the following characters.

Underscore prefixes are common in C code -- a single underscore means "private", and double underscores are usually reserved for use by the compiler.

In case you encounter an error like this

mysqldump: 1044 Access denied when using LOCK TABLES

A quick workaround is to pass the –-single-transaction option to mysqldump.

So your command will be like this.

mysqldump --single-transaction -u user -p DBNAME > backup.sql

Note that the solution to does not start with “hede”:

^(?!hede).*$

is generally much more efficient than the solution to does not contain “hede”:

^((?!hede).)*$

The former checks for “hede” only at the input string’s first position, rather than at every position.

what is an "undefined reference/unresolved external symbol"

I'll try to explain what is an "undefined reference/unresolved external symbol".

note: i use g++ and Linux and all examples is for it

For example we have some code

// src1.cpp
void print();

static int local_var_name; // 'static' makes variable not visible for other modules
int global_var_name = 123;

int main()
{
    print();
    return 0;
}

and

// src2.cpp
extern "C" int printf (const char*, ...);

extern int global_var_name;
//extern int local_var_name;

void print ()
{
    // printf("%d%d\n", global_var_name, local_var_name);
    printf("%d\n", global_var_name);
}

Make object files

$ g++ -c src1.cpp -o src1.o
$ g++ -c src2.cpp -o src2.o

After the assembler phase we have an object file, which contains any symbols to export. Look at the symbols

$ readelf --symbols src1.o
  Num:    Value          Size Type    Bind   Vis      Ndx Name
     5: 0000000000000000     4 OBJECT  LOCAL  DEFAULT    4 _ZL14local_var_name # [1]
     9: 0000000000000000     4 OBJECT  GLOBAL DEFAULT    3 global_var_name     # [2]

I've rejected some lines from output, because they do not matter

So, we see follow symbols to export.

[1] - this is our static (local) variable (important - Bind has a type "LOCAL")
[2] - this is our global variable

src2.cpp exports nothing and we have seen no its symbols

Link our object files

$ g++ src1.o src2.o -o prog

and run it

$ ./prog
123

Linker sees exported symbols and links it. Now we try to uncomment lines in src2.cpp like here

// src2.cpp
extern "C" int printf (const char*, ...);

extern int global_var_name;
extern int local_var_name;

void print ()
{
    printf("%d%d\n", global_var_name, local_var_name);
}

and rebuild an object file

$ g++ -c src2.cpp -o src2.o

OK (no errors), because we only build object file, linking is not done yet. Try to link

$ g++ src1.o src2.o -o prog
src2.o: In function `print()':
src2.cpp:(.text+0x6): undefined reference to `local_var_name'
collect2: error: ld returned 1 exit status

It has happened because our local_var_name is static, i.e. it is not visible for other modules. Now more deeply. Get the translation phase output

$ g++ -S src1.cpp -o src1.s

// src1.s
look src1.s

    .file   "src1.cpp"
    .local  _ZL14local_var_name
    .comm   _ZL14local_var_name,4,4
    .globl  global_var_name
    .data
    .align 4
    .type   global_var_name, @object
    .size   global_var_name, 4
global_var_name:
    .long   123
    .text
    .globl  main
    .type   main, @function
main:
; assembler code, not interesting for us
.LFE0:
    .size   main, .-main
    .ident  "GCC: (Ubuntu 4.8.2-19ubuntu1) 4.8.2"
    .section    .note.GNU-stack,"",@progbits

So, we've seen there is no label for local_var_name, that's why linker hasn't found it. But we are hackers :) and we can fix it. Open src1.s in your text editor and change

.local  _ZL14local_var_name
.comm   _ZL14local_var_name,4,4

to

    .globl  local_var_name
    .data
    .align 4
    .type   local_var_name, @object
    .size   local_var_name, 4
local_var_name:
    .long   456789

i.e. you should have like below

    .file   "src1.cpp"
    .globl  local_var_name
    .data
    .align 4
    .type   local_var_name, @object
    .size   local_var_name, 4
local_var_name:
    .long   456789
    .globl  global_var_name
    .align 4
    .type   global_var_name, @object
    .size   global_var_name, 4
global_var_name:
    .long   123
    .text
    .globl  main
    .type   main, @function
main:
; ...

we have changed the visibility of local_var_name and set its value to 456789. Try to build an object file from it

$ g++ -c src1.s -o src2.o

ok, see readelf output (symbols)

$ readelf --symbols src1.o
8: 0000000000000000     4 OBJECT  GLOBAL DEFAULT    3 local_var_name

now local_var_name has Bind GLOBAL (was LOCAL)

link

$ g++ src1.o src2.o -o prog

and run it

$ ./prog 
123456789

ok, we hack it :)

So, as a result - an "undefined reference/unresolved external symbol error" happens when the linker cannot find global symbols in the object files.

I just got around to doing this myself, so the following is where I am so far in terms of a CentOS init.d service controller script. It's working quite nicely so far, but I'm no leet Bash hacker, so I'm sure there's room for improvement, so thoughts on improving it are welcome.

First of all, I have a short config script /data/svcmgmt/conf/my-spring-boot-api.sh for each service, which sets up environment variables.

#!/bin/bash
export JAVA_HOME=/opt/jdk1.8.0_05/jre
export APP_HOME=/data/apps/my-spring-boot-api
export APP_NAME=my-spring-boot-api
export APP_PORT=40001

I'm using CentOS, so to ensure that my services are started after a server restart, I have a service control script in /etc/init.d/my-spring-boot-api:

#!/bin/bash
# description: my-spring-boot-api start stop restart
# processname: my-spring-boot-api
# chkconfig: 234 20 80

. /data/svcmgmt/conf/my-spring-boot-api.sh

/data/svcmgmt/bin/spring-boot-service.sh $1

exit 0

As you can see, that calls the initial config script to set up environment variables and then calls a shared script which I use for restarting all of my Spring Boot services. That shared script is where the meat of it all can be found:

#!/bin/bash

echo "Service [$APP_NAME] - [$1]"

echo "    JAVA_HOME=$JAVA_HOME"
echo "    APP_HOME=$APP_HOME"
echo "    APP_NAME=$APP_NAME"
echo "    APP_PORT=$APP_PORT"

function start {
    if pkill -0 -f $APP_NAME.jar > /dev/null 2>&1
    then
        echo "Service [$APP_NAME] is already running. Ignoring startup request."
        exit 1
    fi
    echo "Starting application..."
    nohup $JAVA_HOME/bin/java -jar $APP_HOME/$APP_NAME.jar \
        --spring.config.location=file:$APP_HOME/config/   \
        < /dev/null > $APP_HOME/logs/app.log 2>&1 &
}

function stop {
    if ! pkill -0 -f $APP_NAME.jar > /dev/null 2>&1
    then
        echo "Service [$APP_NAME] is not running. Ignoring shutdown request."
        exit 1
    fi

    # First, we will try to trigger a controlled shutdown using 
    # spring-boot-actuator
    curl -X POST http://localhost:$APP_PORT/shutdown < /dev/null > /dev/null 2>&1

    # Wait until the server process has shut down
    attempts=0
    while pkill -0 -f $APP_NAME.jar > /dev/null 2>&1
    do
        attempts=$[$attempts + 1]
        if [ $attempts -gt 5 ]
        then
            # We have waited too long. Kill it.
            pkill -f $APP_NAME.jar > /dev/null 2>&1
        fi
        sleep 1s
    done
}

case $1 in
start)
    start
;;
stop)
    stop
;;
restart)
    stop
    start
;;
esac
exit 0

When stopping, it will attempt to use Spring Boot Actuator to perform a controlled shutdown. However, in case Actuator is not configured or fails to shut down within a reasonable time frame (I give it 5 seconds, which is a bit short really), the process will be killed.

Also, the script makes the assumption that the java process running the appllication will be the only one with "my-spring-boot-api.jar" in the text of the process details. This is a safe assumption in my environment and means that I don't need to keep track of PIDs.

In my case, my dataframe has the following characteristics

<class 'pandas.core.frame.DataFrame'>
Index: 3040 entries, 15/12/2008 to  
Data columns (total 1 columns):
 #   Column  Non-Null Count  Dtype  
---  ------  --------------  -----  
 0   Close   3038 non-null   float64
dtypes: float64(1)
memory usage: 47.5+ KB

The first option data.index = pd.to_datetime(data.index) returned

ParserError: String does not contain a date: ParserError: String does not contain a date:

The second option: data.index.to_datetime() returned

AttributeError: 'Index' object has no attribute 'to_datetime'

It returned

Another option I have tested is. data.index = pd.to_datetime(data.index)

It returned: ParserError: String does not contain a date:

What could be my problem? Thanks

You can use isin method:

In [1]: df = pd.DataFrame({'A': [5,6,3,4], 'B': [1,2,3,5]})

In [2]: df
Out[2]:
   A  B
0  5  1
1  6  2
2  3  3
3  4  5

In [3]: df[df['A'].isin([3, 6])]
Out[3]:
   A  B
1  6  2
2  3  3

And to get the opposite use ~:

In [4]: df[~df['A'].isin([3, 6])]
Out[4]:
   A  B
0  5  1
3  4  5

Contains(s2) is many times (in my computer 10 times) faster than IndexOf(s2) because Contains uses StringComparison.Ordinal that is faster than the culture sensitive search that IndexOf does by default (but that may change in .net 4.0 http://davesbox.com/archive/2008/11/12/breaking-changes-to-the-string-class.aspx).

Contains has exactly the same performance as IndexOf(s2,StringComparison.Ordinal) >= 0 in my tests but it's shorter and makes your intent clear.

Adding to the mentions of jwplayer and possible TOS violations, I would like to to link to the following repository on github: YouTube Audio Player Generation Library, that allows to generate the following output:

Library has the support for the playlists and PHP autorendering given the video URL and the configuration options.

Depends on what you are looking for. If you are looking for the executable :

$ whereis mvn

If you are looking for the libs and repo :

$ locate maven

With the locate command, you could also pipe it to grep to find a particular library, i.e.

$ locate maven | grep 'jetty'

HTH

You can do this by using the following xml

<RelativeLayout
    style="@style/GenericProgressBackground"
    android:id="@+id/loadingPanel"
    >
    <ProgressBar
        style="@style/GenericProgressIndicator"/>
</RelativeLayout>

With this style

<style name="GenericProgressBackground" parent="android:Theme">
    <item name="android:layout_width">fill_parent</item>    
    <item name="android:layout_height">fill_parent</item>
    <item name="android:background">#DD111111</item>    
    <item name="android:gravity">center</item>  
</style>
<style name="GenericProgressIndicator" parent="@android:style/Widget.ProgressBar.Small">
    <item name="android:layout_width">wrap_content</item>
    <item name="android:layout_height">wrap_content</item>
    <item name="android:indeterminate">true</item> 
</style>

To use this, you must hide your UI elements by setting the visibility value to GONE and whenever the data is loaded, call setVisibility(View.VISIBLE) on all your views to restore them. Don't forget to call findViewById(R.id.loadingPanel).setVisiblity(View.GONE) to hide the loading animation.

If you dont have a loading event/function but just want the loading panel to disappear after x seconds use a Handle to trigger the hiding/showing.

You can call this function which generates random colors for each bars

var randomColorGenerator = function () { 
    return '#' + (Math.random().toString(16) + '0000000').slice(2, 8); 
};

var barChartData = {
        labels: ["001", "002", "003", "004", "005", "006", "007"],
        datasets: [
            {
                label: "My First dataset",
                fillColor: randomColorGenerator(), 
                strokeColor: randomColorGenerator(), 
                highlightFill: randomColorGenerator(),
                highlightStroke: randomColorGenerator(),
                data: [20, 59, 80, 81, 56, 55, 40]
            }
        ]
    };

private void comboBox_Loaded(object sender, RoutedEventArgs e)
{
 Combobox.selectedIndex= your index;
}

OR if you want to display some value after comparing into combobox

 foreach (var item in comboBox.Items)
            {
                if (item.ToString().ToLower().Equals("your item in lower"))
                {
                    comboBox.SelectedValue = item;
                }
            }

I hope it will help, it works for me.

In Python we use csv.writer() module to write data into csv files. This module is similar to the csv.reader() module.

import csv

person = [['SN', 'Person', 'DOB'],
['1', 'John', '18/1/1997'],
['2', 'Marie','19/2/1998'],
['3', 'Simon','20/3/1999'],
['4', 'Erik', '21/4/2000'],
['5', 'Ana', '22/5/2001']]

csv.register_dialect('myDialect',
delimiter = '|',
quoting=csv.QUOTE_NONE,
skipinitialspace=True)

with open('dob.csv', 'w') as f:
    writer = csv.writer(f, dialect='myDialect')
    for row in person:
       writer.writerow(row)

f.close()

A delimiter is a string used to separate fields. The default value is comma(,).

If GAAP Compliance is required or you need 4 decimal places:

DECIMAL(13, 4) Which supports a max value of:

$999,999,999.9999

Otherwise, if 2 decimal places is enough: DECIMAL(13,2)

If you append ..\.. to your existing path, the operating system will correctly browse the grand-parent folder.

That should do the job:

System.IO.Path.Combine("C:\\Users\\Masoud\\Documents\\Visual Studio 2008\\Projects\\MyProj\\MyProj\\bin\\Debug", @"..\..");

If you browse that path, you will browse the grand-parent directory.

Or even better, use HTML elements that fit your need. It's cleaner, and produces leaner markup. Example:

<dl>
   <dt>Lorem Ipsum etc <em>here</em></dt>
   <dd>blah</dd>
   <dd>blah blah</dd>
   <dd>blah</dd>
   <dt>lorem ipsums <em>and here</em></dt>
</dl>

Float the em to the right (with display: block), or set it to position: absolute with its parent as position: relative.

As an alternative, you might use a 9 patch image as the background for your layout, allowing for more "natural" shadows:

Result:

Put the image in your /res/drawable folder.
Make sure the file extension is .9.png, not .png

By the way, this is a modified (reduced to the minimum square size) of an existing resource found in the API 19 sdk resources folder.
I left the red markers, since they don't seem to be harmful, as shown in the draw9patch tool.

[EDIT]

About 9 patches, in case you never had anything to do with them.

Simply add it as the background of your View.

The black-marked areas (left and top) will stretch (vertically, horizontally).
The black-marked areas (right, bottom) define the "content area" (where it's possible to add text or Views - you can call the unmarked regions "padding", if you like to).

Tutorial: http://radleymarx.com/blog/simple-guide-to-9-patch/

Use this. Works fine

input.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL | InputType.TYPE_NUMBER_FLAG_SIGNED);
input.setKeyListener(DigitsKeyListener.getInstance("0123456789"));

EDIT

kotlin version

fun EditText.onlyNumbers() {
    inputType = InputType.TYPE_CLASS_NUMBER or InputType.TYPE_NUMBER_FLAG_DECIMAL or
        InputType.TYPE_NUMBER_FLAG_SIGNED
    keyListener = DigitsKeyListener.getInstance("0123456789")
}

Yes. You can tell the OS what kind of transition you want to have for your activity.

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

    ...

}

Where ANIMATION is an integer referring to a built in animation in the OS.

You can't write binary literals like 00101011 in Java so you can write it in hexadecimal instead:

byte x = 0x2b;

To calculate the result of x >> 2 you can then just write exactly that and print the result.

System.out.println(x >> 2);

You can check the output of a TensorObject without running the graph in a session, by enabling eager execution.

Simply add the following two lines of code: import tensorflow.contrib.eager as tfe tfe.enable_eager_execution()

right after you import tensorflow.

The output of print product in your example will now be: tf.Tensor([[ 12.]], shape=(1, 1), dtype=float32)

Note that as of now (November 2017) you'll have to install a Tensorflow nightly build to enable eager execution. Pre-built wheels can be found here.

Here's the same as the current top answer, but in an ES6 one-liner:

myArray.sort((a, b) => a.distance - b.distance);

You need to set a constraint on the table to trigger a "conflict" which you then resolve by doing a replace:

CREATE TABLE data   (id INTEGER PRIMARY KEY, event_id INTEGER, track_id INTEGER, value REAL);
CREATE UNIQUE INDEX data_idx ON data(event_id, track_id);

Then you can issue:

INSERT OR REPLACE INTO data VALUES (NULL, 1, 2, 3);
INSERT OR REPLACE INTO data VALUES (NULL, 2, 2, 3);
INSERT OR REPLACE INTO data VALUES (NULL, 1, 2, 5);

The "SELECT * FROM data" will give you:

2|2|2|3.0
3|1|2|5.0

Note that the data.id is "3" and not "1" because REPLACE does a DELETE and INSERT, not an UPDATE. This also means that you must ensure that you define all necessary columns or you will get unexpected NULL values.

You can do this using a combination of the Element.scrollHeight and Element.clientHeight attributes.

According to MDN:

The Element.scrollHeight read-only attribute is a measurement of the height of an element's content, including content not visible on the screen due to overflow. The scrollHeight value is equal to the minimum clientHeight the element would require in order to fit all the content in the viewpoint without using a vertical scrollbar. It includes the element padding but not its margin.

And:

The Element.clientHeight read-only property returns the inner height of an element in pixels, including padding but not the horizontal scrollbar height, border, or margin.

clientHeight can be calculated as CSS height + CSS padding - height of horizontal scrollbar (if present).

Therefore, the element will display a scrollbar if the scroll height is greater than the client height, so the answer to your question is:

function scrollbarVisible(element) {
  return element.scrollHeight > element.clientHeight;
}

Try:

EditText edt = (EditText) findViewById(R.id.YourEditText);
RelativeLayout.LayoutParams lp =
    new RelativeLayout.LayoutParams
    (
        LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT
    );
lp.setMargins(25, 0, 0, 0); // move 25 px to right (increase left margin)
edt.setLayoutParams(lp); // lp.setMargins(left, top, right, bottom);

For those who use Tomcat with Bitronix, this will fix the problem:

The error indicates that no handler could be found for your datasource 'jdbc/mydb', so you'll need to make sure your tomcat server refers to your bitronix configuration files as needed.

In case you're using btm-config.properties and resources.properties files to configure the datasource, specify these two JVM arguments in tomcat:

(if you already used them, make sure your references are correct):

• btm.root
• bitronix.tm.configuration

e.g.

-Dbtm.root="C:\Program Files\Apache Software Foundation\Tomcat 7.0.59" 
-Dbitronix.tm.configuration="C:\Program Files\Apache Software Foundation\Tomcat 7.0.59\conf\btm-config.properties" 

Now, restart your server and check the log.

I got this error using Java and PostgreSQL doing an insert on a table. I will illustrate how you can reproduce this error:

org.postgresql.util.PSQLException: ERROR: 
current transaction is aborted, commands ignored until end of transaction block

Summary:

The reason you get this error is because you have entered a transaction and one of your SQL Queries failed, and you gobbled up that failure and ignored it. But that wasn't enough, THEN you used that same connection, using the SAME TRANSACTION to run another query. The exception gets thrown on the second, correctly formed query because you are using a broken transaction to do additional work. PostgreSQL by default stops you from doing this.

I'm using: PostgreSQL 9.1.6 on x86_64-redhat-linux-gnu, compiled by gcc (GCC) 4.7.2 20120921 (Red Hat 4.7.2-2), 64-bit".

My PostgreSQL driver is: postgresql-9.2-1000.jdbc4.jar

Using Java version: Java 1.7

Here is the table create statement to illustrate the Exception:

CREATE TABLE moobar
(
    myval   INT
);

Java program causes the error:

public void postgresql_insert()
{
    try  
    {
        connection.setAutoCommit(false);  //start of transaction.
        
        Statement statement = connection.createStatement();
        
        System.out.println("start doing statement.execute");
        
        statement.execute(
                "insert into moobar values(" +
                "'this SQL statement fails, and it " +
                "is gobbled up by the catch, okfine'); ");
     
        //The above line throws an exception because we try to cram
        //A string into an Int.  I Expect this, what happens is we gobble 
        //the Exception and ignore it like nothing is wrong.
        //But remember, we are in a TRANSACTION!  so keep reading.

        System.out.println("statement.execute done");
        
        statement.close();
        
    }
    catch (SQLException sqle)
    {
        System.out.println("keep on truckin, keep using " +
                "the last connection because what could go wrong?");
    }
    
    try{
        Statement statement = connection.createStatement();
        
        statement.executeQuery("select * from moobar");

        //This SQL is correctly formed, yet it throws the 
        //'transaction is aborted' SQL Exception, why?  Because:
        //A.  you were in a transaction.
        //B.  You ran a SQL statement that failed.
        //C.  You didn't do a rollback or commit on the affected connection.
        
    }
    catch (SQLException sqle)
    {
        sqle.printStackTrace();
    }   

}

The above code produces this output for me:

start doing statement.execute

keep on truckin, keep using the last connection because what could go wrong?

org.postgresql.util.PSQLException: 
  ERROR: current transaction is aborted, commands ignored until 
  end of transaction block

Workarounds:

You have a few options:

1. Simplest solution: Don't be in a transaction. Set the connection.setAutoCommit(false); to connection.setAutoCommit(true);. It works because then the failed SQL is just ignored as a failed SQL statement. You are welcome to fail SQL statements all you want and PostgreSQL won't stop you.

2. Stay being in a transaction, but when you detect that the first SQL has failed, either rollback/re-start or commit/restart the transaction. Then you can continue failing as many SQL queries on that database connection as you want.

3. Don't catch and ignore the Exception that is thrown when a SQL statement fails. Then the program will stop on the malformed query.

4. Get Oracle instead, Oracle doesn't throw an exception when you fail a query on a connection within a transaction and continue using that connection.

In defense of PostgreSQL's decision to do things this way... Oracle was making you soft in the middle letting you do dumb stuff and overlooking it.

When working with fragments, instead of using this or refering to the context, always use getActivity(). You should call

getActivity().finish();

to finish your activity from fragment.

This code works for me:

$rootScope.$$listeners.nameOfYourEvent=[];

for line in reversed(open("file").readlines()):
    print line.rstrip()

If you are on linux, you can use tac command.

$ tac file

2 recipes you can find in ActiveState here and here

This should work - imageButton.setBackgroundColor(android.R.color.transparent);

Also you can use default() filter. Or just a shortcut d()

- name: Generating a new SSH key for the current user it's not exists already
  local_action:
    module: user
    name: "{{ login_user.stdout }}"
    generate_ssh_key: yes

  when: 
    - sshkey_result.rc == 1
    - github_username | d('none') | lower == 'none'

Adding a bit to mitigate the confusion here. Even though Darren Davies' (accepted) answer is more straight forward, I think Andrei's answer is a better approach for MVC applications.

The answer from Andrei means that you can use HttpContext just as you would use System.Web.HttpContext.Current. For example, if you want to do this:

System.Web.HttpContext.Current.User.Identity.Name

you should instead do this:

HttpContext.User.Identity.Name

Both achieve the same result, but (again) in terms of MVC, the latter is more recommended.

Another good and also straight forward information regarding this matter can be found here: Difference between HttpContext.Current and Controller.Context in MVC ASP.NET.

Use "clearfix" instead of "row". It does the exact same except it doesn't have a negative margin. Step through the "row" usage and you'll see that's the only difference.

Try following these steps:

1. Run Chrome as Administrator.
2. Go to the settings in Chrome.
3. Go to Advanced Settings (its all the way down).
4. Scroll to Network Section and click on ''Change proxy settings''.
5. A window will pop up with the name ''Internet Properties''
6. Click on ''LAN settings''
7. Un-check ''Use a proxy server for your LAN''
8. Check ''Automatically detect settings''
9. Click everything ''OK'' and you are done!

You can use some div or span instead of button and then on click call some function which submits form at he end.

<form id="my_form">
   <span onclick="submit()">submit</span>
</form>

<script>
   function submit()
   {   
       //do something
       $("#my_form").submit();

According to the latest document when state is set to be directory, you don't need to use parameter recurse to create parent directories, file module will take care of it.

- name: create directory with parent directories
  file:
    path: /data/test/foo
    state: directory

this is fare enough to create the parent directories data and test with foo

please refer the parameter description - "state" http://docs.ansible.com/ansible/latest/modules/file_module.html

If you are not required to use Apple's look and feel, a simple fix is to put the following code in your application or applet, before you add any GUI components to your JFrame or JApplet:

 try {
    UIManager.setLookAndFeel( UIManager.getCrossPlatformLookAndFeelClassName() );
 } catch (Exception e) {
            e.printStackTrace();
 }

That will set the look and feel to the cross-platform look and feel, and the setBackground() method will then work to change a JButton's background color.

if you install MySQL-python in your virtual env, you should check the pip version, if the version is older than 9.0.1, please update it

pip install --upgrade pip

When using a MVC framework I put the following in my controller.

request.setAttribute(RequestParameterNamesEnum.INBOX_ACTION.name(), RequestParameterNamesEnum.INBOX_ACTION.name());

This allows me to use the following in my JSP Page.

<script> var url = 'http://www.nowhere.com/?${INBOX_ACTION}=' + someValue;</script>

It can also be used in your comparison

<c:when test="${someModel.action == INBOX_ACTION}">

Which I prefer over putting in a string literal.
