Using the SVG from @ArnoTenkink as an data url combined with the accepted answer, this gives us the perfect solution for retina displays.

No compiler worth its weight in salt will run differently between

for(int i=0; i<10; i++)

and

for(int i=0;i<10;++i)

++i and i++ have the same cost. The only thing that differs is that the return value of ++i is i+1 whereas the return value of i++ is i.

So for those prefering ++i, there's probably no valid justification, just personal preference.

EDIT: This is wrong for classes, as said in about every other post. i++ will generate a copy if i is a class.

It's possibly a 32 - 64 bits mismatch.

If you're running on a 64-bit OS, the Assembly RevitAPI may be compiled as 32-bit and your process as 64-bit or "Any CPU".

Or, the RevitAPI is compiled as 64-bit and your process is compiled as 32-bit or "Any CPU" and running on a 32-bit OS.

Explicitly cast it as a double

double g = 1.0/3.0

This happens because Java uses the integer division operation for 1 and 3 since you entered them as integer constants.

When you are using foreach loop within view for binded model ... Your model is supposed to be in listed format.

i.e

@model IEnumerable<ViewModels.MyViewModels>


        @{
            if (Model.Count() > 0)
            {            

                @Html.DisplayFor(modelItem => Model.Theme.FirstOrDefault().name)
                @foreach (var theme in Model.Theme)
                {
                   @Html.DisplayFor(modelItem => theme.name)
                   @foreach(var product in theme.Products)
                   {
                      @Html.DisplayFor(modelItem => product.name)
                      @foreach(var order in product.Orders)
                      {
                          @Html.TextBoxFor(modelItem => order.Quantity)
                         @Html.TextAreaFor(modelItem => order.Note)
                          @Html.EditorFor(modelItem => order.DateRequestedDeliveryFor)
                      }
                  }
                }
            }else{
                   <span>No Theam avaiable</span>
            }
        }

A simple way using std::next_permutation:

#include <iostream>
#include <algorithm>
#include <vector>

int main() {
    int n, r;
    std::cin >> n;
    std::cin >> r;

    std::vector<bool> v(n);
    std::fill(v.end() - r, v.end(), true);

    do {
        for (int i = 0; i < n; ++i) {
            if (v[i]) {
                std::cout << (i + 1) << " ";
            }
        }
        std::cout << "\n";
    } while (std::next_permutation(v.begin(), v.end()));
    return 0;
}

or a slight variation that outputs the results in an easier to follow order:

#include <iostream>
#include <algorithm>
#include <vector>

int main() {
   int n, r;
   std::cin >> n;
   std::cin >> r;

   std::vector<bool> v(n);
   std::fill(v.begin(), v.begin() + r, true);

   do {
       for (int i = 0; i < n; ++i) {
           if (v[i]) {
               std::cout << (i + 1) << " ";
           }
       }
       std::cout << "\n";
   } while (std::prev_permutation(v.begin(), v.end()));
   return 0;
}

A bit of explanation:

It works by creating a "selection array" (v), where we place r selectors, then we create all permutations of these selectors, and print the corresponding set member if it is selected in in the current permutation of v.

You can implement it if you note that for each level r you select a number from 1 to n.

In C++, we need to 'manually' keep the state between calls that produces results (a combination): so, we build a class that on construction initialize the state, and has a member that on each call returns the combination while there are solutions: for instance

#include <iostream>
#include <iterator>
#include <vector>
#include <cstdlib>

using namespace std;

struct combinations
{
    typedef vector<int> combination_t;

    // initialize status
   combinations(int N, int R) :
       completed(N < 1 || R > N),
       generated(0),
       N(N), R(R)
   {
       for (int c = 1; c <= R; ++c)
           curr.push_back(c);
   }

   // true while there are more solutions
   bool completed;

   // count how many generated
   int generated;

   // get current and compute next combination
   combination_t next()
   {
       combination_t ret = curr;

       // find what to increment
       completed = true;
       for (int i = R - 1; i >= 0; --i)
           if (curr[i] < N - R + i + 1)
           {
               int j = curr[i] + 1;
               while (i <= R-1)
                   curr[i++] = j++;
               completed = false;
               ++generated;
               break;
           }

       return ret;
   }

private:

   int N, R;
   combination_t curr;
};

int main(int argc, char **argv)
{
    int N = argc >= 2 ? atoi(argv[1]) : 5;
    int R = argc >= 3 ? atoi(argv[2]) : 2;
    combinations cs(N, R);
    while (!cs.completed)
    {
        combinations::combination_t c = cs.next();
        copy(c.begin(), c.end(), ostream_iterator<int>(cout, ","));
        cout << endl;
    }
    return cs.generated;
}

test output:

1,2,
1,3,
1,4,
1,5,
2,3,
2,4,
2,5,
3,4,
3,5,
4,5,

Because your else isn't attached to anything. The if without braces only encompasses the single statement that immediately follows it.

if (choice==5)
{
    System.out.println("End of Game\n Thank you for playing with us!");
    break;
}
else
{
   System.out.println("Not a valid choice!\n Please try again...\n");
}

Not using braces is generally viewed as a bad practice because it can lead to the exact problems you encountered.

In addition, using a switch here would make more sense.

int choice;
boolean keepGoing = true;
while(keepGoing)
{
    System.out.println("---> Your choice: ");
    choice = input.nextInt();
    switch(choice)
    {
        case 1: 
            playGame();
            break;
        case 2: 
            loadGame();
            break;
        // your other cases
        // ...
        case 5: 
            System.out.println("End of Game\n Thank you for playing with us!");
            keepGoing = false;
            break;
        default:
            System.out.println("Not a valid choice!\n Please try again...\n");
     }
 }         

Note that instead of an infinite for loop I used a while(boolean), making it easy to exit the loop. Another approach would be using break with labels.

Unique Keys: The columns in which no two rows are similar

Primary Key: Collection of minimum number of columns which can uniquely identify every row in a table (i.e. no two rows are similar in all the columns constituting primary key). There can be more than one primary key in a table. If there exists a unique-key then it is primary key (not "the" primary key) in the table. If there does not exist a unique key then more than one column values will be required to identify a row like (first_name, last_name, father_name, mother_name) can in some tables constitute primary key.

Index: used to optimize the queries. If you are going to search or sort the results on basis of some column many times (eg. mostly people are going to search the students by name and not by their roll no.) then it can be optimized if the column values are all "indexed" for example with a binary tree algorithm.

Use function Number();

$(function() {_x000D_
_x000D_
  var price1 = 1000;_x000D_
  var price2 = 500000;_x000D_
  var price3 = 15245000;_x000D_
_x000D_
  $("span#s1").html(Number(price1).toLocaleString('en'));_x000D_
  $("span#s2").html(Number(price2).toLocaleString('en'));_x000D_
  $("span#s3").html(Number(price3).toLocaleString('en'));_x000D_
_x000D_
  console.log(Number(price).toLocaleString('en'));_x000D_
_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>_x000D_
_x000D_
<span id="s1"></span><br />_x000D_
<span id="s2"></span><br />_x000D_

You need to use regular expressions in your custom validator. For example, here's the code that allows only 9 digits in the input fields:

function ssnValidator(control: FormControl): {[key: string]: any} {
  const value: string = control.value || '';
  const valid = value.match(/^\d{9}$/);
  return valid ? null : {ssn: true};
}

Take a look at a sample app here:

Solution:

To your secondary question

var elem1 = $('#elem1'),
    elem2 = $('#elem2'),
    elem3 = $('#elem3');

You can use the variable as the replacement of selector.

elem1.css({'display':'none'}); //will work

In the below case selector is already stored in a variable.

$(elem1,elem2,elem3).css({'display':'none'}); // will not work

If you disable the Program Compatibility Mode and the problem persists, copy the content of ISO to a local path and try install with a simple double click

Replace

volume = (4 / 3) Math.PI * Math.pow(radius, 3);

With:

volume = (4 * Math.PI * Math.pow(radius, 3)) / 3;

Try

onsubmit="return checkRegistration()"

Just unchecking offline mode did not work for me.

while spring.jpa.open-in-view was true, I didn't have any problem with getOne but after setting it to false , i got LazyInitializationException. Then problem was solved by replacing with findById.
Although there is another solution without replacing the getOne method, and that is put @Transactional at method which is calling repository.getOne(id). In this way transaction will exists and session will not be closed in your method and while using entity there would not be any LazyInitializationException.

int Random = (int)(Math.random()*100);

if You need to generate more than one value, then just use for loop for that

 for (int i = 1; i <= 10 ; i++)
       {
        int Random = (int)(Math.random()*100);
        System.out.println(Random);
       }

If You want to specify a more decent range, like from 10 to 100 ( both are in the range )

so the code would be :

   int Random =10 +  (int)(Math.random()*(91));
   /* int Random = (min.value ) + (int)(Math.random()* ( Max - Min + 1));
  *Where min is the smallest value You want to be the smallest number possible to       
  generate and Max is the biggest possible number to generate*/

Escaping quotes in VB6 or VBScript strings is simple in theory although often frightening when viewed. You escape a double quote with another double quote.

An example:

"c:\program files\my app\app.exe"

If I want to escape the double quotes so I could pass this to the shell execute function listed by Joe or the VB6 Shell function I would write it:

escapedString = """c:\program files\my app\app.exe"""

How does this work? The first and last quotes wrap the string and let VB know this is a string. Then each quote that is displayed literally in the string has another double quote added in front of it to escape it.

It gets crazier when you are trying to pass a string with multiple quoted sections. Remember, every quote you want to pass has to be escaped.

If I want to pass these two quoted phrases as a single string separated by a space (which is not uncommon):

"c:\program files\my app\app.exe" "c:\documents and settings\steve"

I would enter this:

escapedQuoteHell = """c:\program files\my app\app.exe"" ""c:\documents and settings\steve"""

I've helped my sysadmins with some VBScripts that have had even more quotes.

It's not pretty, but that's how it works.

$('img.conversation_img[alt="example"]')
    .each(function(){
         alert($(this).attr('src'))
    });

This will display src attributes of all images of class 'conversation_img' with alt='example'

It turns out that writing a performant scaler is not trivial. I did it once for an open source project: ImageScaler.

In principle 'java.awt.Image#getScaledInstance(int, int, int)' would do the job as well, but there is a nasty bug with this - refer to my link for details.

The Helvetica font does not come included with Windows, so to use it you must download it as a .ttf file. Then you can refer matplotlib to it like this (replace "crm10.ttf" with your file):

import os
from matplotlib import font_manager as fm, rcParams
import matplotlib.pyplot as plt

fig, ax = plt.subplots()

fpath = os.path.join(rcParams["datapath"], "fonts/ttf/cmr10.ttf")
prop = fm.FontProperties(fname=fpath)
fname = os.path.split(fpath)[1]
ax.set_title('This is a special font: {}'.format(fname), fontproperties=prop)
ax.set_xlabel('This is the default font')

plt.show()

print(fpath) will show you where you should put the .ttf.

You can see the output here: https://matplotlib.org/gallery/api/font_file.html

A good example is Git, which uses a strategy to store blobs. Why does it use hashes? Partly because these are easier to perform diffs on, but also because makes it simpler to optimise a COW strategy. When you make a new commit with few files changes the vast majority of objects and trees will not change. Therefore the commit, will through various pointers made of hashes reference a bunch of object that already exist, making the storage space required to store the entire history much smaller.

Try invoking your command with Invoke-Expression:

Invoke-Expression $cmd1

Here is a working example on my machine:

$cmd = "& 'C:\Program Files\7-zip\7z.exe' a -tzip c:\temp\test.zip c:\temp\test.txt"
Invoke-Expression $cmd

iex is an alias for Invoke-Expression so you could do:

iex $cmd1

The Yahoo! Exceptional Performance team recommend placing scripts at the bottom of your page because of the way browsers download components.

Of course Levi's comment "just before you need it and no sooner" is really the correct answer, i.e. "it depends".

I just customized BootPc Deutschland's answer

You can simply use

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script>
    $(document).ready(function(){
        $('body,html').animate({
            scrollTop: 0
        }, 800);
    $('#btn-go-to-top').click(function () {
        $('body,html').animate({
            scrollTop: 0
        }, 800);
        return false;
    });
}); 
</script>

this will help you to smoothly scroll to the top of the page.

and for styling

#btn-go-to-top {
opacity: .5;
width:4%;
height:8%;
display: none;
position: fixed;
bottom: 5%;
right: 3%;
z-index: 99;
border: none;
outline: none;
background-color: red;
color: white;
cursor: pointer;
padding: 10px;
 border-radius: 50%;
}

#btn-go-to-top:hover {
opacity: 1;
}
.top {
transition: all 0.5s ease 0s;
-moz-transition: all 0.5s ease 0s;
-webkit-transition: all 0.5s ease 0s;
-o-transition: all 0.5s ease 0s;
}

this styling makes the button arrive at the bottom-right of the page.

and in your page you can add the button to go to top like this

<div id="btn-go-to-top" class="text-center top">
<img src="uploads/Arrow.png" style="margin: 7px;" width="50%" height="50%">
</div>

I like dynamic typing because it gets out of my way, but yes runtime errors can creep up that I didn't plan for. Where as static typing may fix the aforementioned errors, but drive a novice(in typed languages) programmer crazy trying to cast between a constant char and a string.

Python3. Use inspect to capture the calling local namespace then use ideas presented here. Can return more than one answer as has been pointed out.

def varname(var):

  frame = inspect.currentframe()
  var_id = id(var)
  for name in frame.f_back.f_locals.keys():
    try:
      if id(eval(name)) == var_id:
        return(name)
    except:
      pass

A Java String is an Object. (String extends Object.)

So you can get an Object reference via assignment/initialisation:

String a = "abc";
Object b = a;

 #alertlist li:hover:after,#alertlist li.selected:after
{
    position:absolute;
    top: 0;
    right:-10px;
    bottom:0;

    border-top: 10px solid transparent;
    border-bottom: 10px solid transparent;
    border-left: 10px solid #303030;
    content: "";
}?

I had similar situation. I found that one of my config maps was duplicated. I had two configmaps for the same namespace. One had the correct namespace reference, the other was pointing to the wrong namespace.

I deleted and recreated the configmap with the correct file (or fixed file). I am only using one, and that seemed to make the particular cluster happier.

So I would check the files for any typos or duplicate items that could be causing conflict.

The reasons why (including the data in the leaf level of the index) have been nicely explained. The reason that you give two shakes about this, is that when you run your query, if you don't have the additional columns included (new feature in SQL 2005) the SQL Server has to go to the clustered index to get the additional columns which takes more time, and adds more load to the SQL Server service, the disks, and the memory (buffer cache to be specific) as new data pages are loaded into memory, potentially pushing other more often needed data out of the buffer cache.

I don't understand why Nick is using margin-left: 200px; instead off floating the other div to the left or right, I've just tweaked his markup, you can use float for both elements instead of using margin-left.

Demo

#main {
    margin: auto;
    width: 400px;
}

#sidebar    {
    width: 100px;
    min-height: 400px;
    background: red;
    float: left;
}

#page-wrap  {
    width: 300px;
    background: #0f0;
    min-height: 400px;
    float: left;
}

.clear:after {
    clear: both;
    display: table;
    content: "";
}

Also, I've used .clear:after which am calling on the parent element, just to self clear the parent.

At a guess, you used Code::Blocks to create a Console Application project. Such a project does not link in the GDI stuff, because console applications are generally not intended to do graphics, and TextOut is a graphics function. If you want to use the features of the GDI, you should create a Win32 Gui Project, which will be set up to link in the GDI for you.

See What are the nuances of scope prototypal / prototypical inheritance in AngularJS?

To summarize: the way a directive accesses its parent ($parent) scope depends on the type of scope the directive creates:

1. default (scope: false) - the directive does not create a new scope, so there is no inheritance here. The directive's scope is the same scope as the parent/container. In the link function, use the first parameter (typically scope).

2. scope: true - the directive creates a new child scope that prototypically inherits from the parent scope. Properties that are defined on the parent scope are available to the directive scope (because of prototypal inheritance). Just beware of writing to a primitive scope property -- that will create a new property on the directive scope (that hides/shadows the parent scope property of the same name).

3. scope: { ... } - the directive creates a new isolate/isolated scope. It does not prototypically inherit the parent scope. You can still access the parent scope using $parent, but this is not normally recommended. Instead, you should specify which parent scope properties (and/or function) the directive needs via additional attributes on the same element where the directive is used, using the =, @, and & notation.

4. transclude: true - the directive creates a new "transcluded" child scope, which prototypically inherits from the parent scope. If the directive also creates an isolate scope, the transcluded and the isolate scopes are siblings. The $parent property of each scope references the same parent scope.
   Angular v1.3 update: If the directive also creates an isolate scope, the transcluded scope is now a child of the isolate scope. The transcluded and isolate scopes are no longer siblings. The $parent property of the transcluded scope now references the isolate scope.

The above link has examples and pictures of all 4 types.

You cannot access the scope in the directive's compile function (as mentioned here: https://github.com/angular/angular.js/wiki/Dev-Guide:-Understanding-Directives). You can access the directive's scope in the link function.

Watching:

For 1. and 2. above: normally you specify which parent property the directive needs via an attribute, then $watch it:

<div my-dir attr1="prop1"></div>

scope.$watch(attrs.attr1, function() { ... });

If you are watching an object property, you'll need to use $parse:

<div my-dir attr2="obj.prop2"></div>

var model = $parse(attrs.attr2);
scope.$watch(model, function() { ... });

For 3. above (isolate scope), watch the name you give the directive property using the @ or = notation:

<div my-dir attr3="{{prop3}}" attr4="obj.prop4"></div>

scope: {
  localName3: '@attr3',
  attr4:      '='  // here, using the same name as the attribute
},
link: function(scope, element, attrs) {
   scope.$watch('localName3', function() { ... });
   scope.$watch('attr4',      function() { ... });

I am tempted to squeeze in my favourite solution. The resulting table will consist of 2 columns: PosIdx for position of the found integer; and Value in integer.

create function FnSplitToTableInt
(
    @param nvarchar(4000)
)
returns table as
return
    with Numbers(Number) as 
    (
        select 1 
        union all 
        select Number + 1 from Numbers where Number < 4000
    ),
    Found as
    (
        select 
            Number as PosIdx,
            convert(int, ltrim(rtrim(convert(nvarchar(4000), 
                substring(@param, Number, 
                charindex(N',' collate Latin1_General_BIN, 
                @param + N',', Number) - Number))))) as Value
        from   
            Numbers 
        where  
            Number <= len(@param)
        and substring(N',' + @param, Number, 1) = N',' collate Latin1_General_BIN
    )
    select 
        PosIdx, 
        case when isnumeric(Value) = 1 
            then convert(int, Value) 
            else convert(int, null) end as Value 
    from 
        Found

It works by using recursive CTE as the list of positions, from 1 to 100 by default. If you need to work with string longer than 100, simply call this function using 'option (maxrecursion 4000)' like the following:

select * from FnSplitToTableInt
(
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0, ' + 
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0, ' +
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0, ' +
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0, ' +
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0'
) 
option (maxrecursion 4000)

You should use DrawEllipse:

//
// Summary:
//     Draws an ellipse defined by a bounding rectangle specified by coordinates
//     for the upper-left corner of the rectangle, a height, and a width.
//
// Parameters:
//   pen:
//     System.Drawing.Pen that determines the color, width,
//      and style of the ellipse.
//
//   x:
//     The x-coordinate of the upper-left corner of the bounding rectangle that
//     defines the ellipse.
//
//   y:
//     The y-coordinate of the upper-left corner of the bounding rectangle that
//     defines the ellipse.
//
//   width:
//     Width of the bounding rectangle that defines the ellipse.
//
//   height:
//     Height of the bounding rectangle that defines the ellipse.
//
// Exceptions:
//   System.ArgumentNullException:
//     pen is null.
public void DrawEllipse(Pen pen, int x, int y, int width, int height);

Try adding root path.

app.get('/', function(req, res) {
    res.sendFile('index.html', { root: __dirname });
});

I got this error after using $.getJSON() from JQuery. I just changed to post:

data = getDataObjectByForm(form);
var jqxhr = $.post(url, data, function(){}, 'json')
    .done(function (response) {
        if (response instanceof Object)
            var json = response;
        else
            var json = $.parseJSON(response);
        // console.log(response);
        // console.log(json);
        jsonToDom(json);
        if (json.reload != undefined && json.reload)
            location.reload();
        $("body").delay(1000).css("cursor", "default");
    })
    .fail(function (jqxhr, textStatus, error) {
        var err = textStatus + ", " + error;
        console.log("Request Failed: " + err);
        alert("Fehler!");
    });

Transient, scoped and singleton define object creation process in ASP.NET MVC core DI when multiple objects of the same type have to be injected. In case you are new to dependency injection you can see this DI IoC video.

You can see the below controller code in which I have requested two instances of "IDal" in the constructor. Transient, Scoped and Singleton define if the same instance will be injected in "_dal" and "_dal1" or different.

public class CustomerController : Controller
{
    IDal dal = null;

    public CustomerController(IDal _dal,
                              IDal _dal1)
    {
        dal = _dal;
        // DI of MVC core
        // inversion of control
    }
}

Transient: In transient, new object instances will be injected in a single request and response. Below is a snapshot image where I displayed GUID values.

Scoped: In scoped, the same object instance will be injected in a single request and response.

Singleton: In singleton, the same object will be injected across all requests and responses. In this case one global instance of the object will be created.

Below is a simple diagram which explains the above fundamental visually.

The above image was drawn by the SBSS team when I was taking ASP.NET MVC training in Mumbai. A big thanks goes to the SBSS team for creating the above image.

# 10GB
SIZE="10"


# check the current size
CHECK="`du -hs /media/662499e1-b699-19ad-57b3-acb127aa5a2b/Aufnahmen`"
CHECK=${CHECK%G*}
echo "Current Foldersize: $CHECK GB"

if (( $(echo "$CHECK > $SIZE" |bc -l) )); then
        echo "Folder is bigger than $SIZE GB"
else
        echo "Folder is smaller than $SIZE GB"
fi

nth-last-child sounds like it was specifically designed to solve this problem, so I doubt whether there is a more compatible alternative. Support looks pretty decent, though.

The syntax for index hints is documented here:
http://dev.mysql.com/doc/refman/5.6/en/index-hints.html

FORCE INDEX goes right after the table reference:

SELECT * FROM (
    SELECT owner_id,
           product_id,
           start_time,
           price,
           currency,
           name,
           closed,
           active,
           approved,
           deleted,
           creation_in_progress
    FROM db_products FORCE INDEX (products_start_time)
    ORDER BY start_time DESC
) as resultstable
WHERE resultstable.closed = 0
      AND resultstable.active = 1
      AND resultstable.approved = 1
      AND resultstable.deleted = 0
      AND resultstable.creation_in_progress = 0
GROUP BY resultstable.owner_id
ORDER BY start_time DESC

WARNING:

If you're using ORDER BY before GROUP BY to get the latest entry per owner_id, you're using a nonstandard and undocumented behavior of MySQL to do that.

There's no guarantee that it'll continue to work in future versions of MySQL, and the query is likely to be an error in any other RDBMS.

Search the greatest-n-per-group tag for many explanations of better solutions for this type of query.

There is also an alternative: you could use the open-source jTDS driver for MS-SQL Server, which is compatible although not made by Microsoft. For that driver, there is a maven artifact that you can use:

http://jtds.sourceforge.net/

From http://mvnrepository.com/artifact/net.sourceforge.jtds/jtds :

<dependency>
    <groupId>net.sourceforge.jtds</groupId>
    <artifactId>jtds</artifactId>
    <version>1.3.1</version>
</dependency>

UPDATE nov 2016, Microsoft now published its MSSQL JDBC driver on github and it's also available on maven now:

<dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>mssql-jdbc</artifactId>
    <version>6.1.0.jre8</version>

I can't get it to work on $.get() because it has no complete event.

I suggest to use $.ajax() like this,

$.ajax({
    url: 'http://www.example.org',
    data: {'a':1,'b':2,'c':3},
    dataType: 'xml',
    complete : function(){
        alert(this.url)
    },
    success: function(xml){
    }
});

In python:

def lcm(*args):
    """Calculates lcm of args"""
    biggest = max(args) #find the largest of numbers
    rest = [n for n in args if n != biggest] #the list of the numbers without the largest
    factor = 1 #to multiply with the biggest as long as the result is not divisble by all of the numbers in the rest
    while True:
        #check if biggest is divisble by all in the rest:
        ans = False in [(biggest * factor) % n == 0 for n in rest]
        #if so the clm is found break the loop and return it, otherwise increment factor by 1 and try again
        if not ans:
            break
        factor += 1
    biggest *= factor

'lcm of (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19) is 232792560'

Internet Explorer doesn't fully support Flexbox due to:

Partial support is due to large amount of bugs present (see known issues).

_{Screenshot and infos taken from caniuse.com}

Notes

Internet Explorer before 10 doesn't support Flexbox, while IE 11 only supports the 2012 syntax.

Known issues

• IE 11 requires a unit to be added to the third argument, the flex-basis property see MSFT documentation.
• In IE10 and IE11, containers with display: flex and flex-direction: column will not properly calculate their flexed childrens' sizes if the container has min-height but no explicit height property. See bug.
• In IE10 the default value for flex is 0 0 auto rather than 0 1 auto as defined in the latest spec.
• IE 11 does not vertically align items correctly when min-height is used. See bug.

Workarounds

Flexbugs is a community-curated list of Flexbox issues and cross-browser workarounds for them. Here's a list of all the bugs with a workaround available and the browsers that affect.

1. Minimum content sizing of flex items not honored
2. Column flex items set to align-items: center overflow their container
3. min-height on a flex container won't apply to its flex items
4. flex shorthand declarations with unitless flex-basis values are ignored
5. Column flex items don't always preserve intrinsic aspect ratios
6. The default flex value has changed
7. flex-basis doesn't account for box-sizing: border-box
8. flex-basis doesn't support calc()
9. Some HTML elements can't be flex containers
10. align-items: baseline doesn't work with nested flex containers
11. Min and max size declarations are ignored when wrapping flex items
12. Inline elements are not treated as flex-items
13. Importance is ignored on flex-basis when using flex shorthand
14. Shrink-to-fit containers with flex-flow: column wrap do not contain their items
15. Column flex items ignore margin: auto on the cross axis
16. flex-basis cannot be animated
17. Flex items are not correctly justified when max-width is used

The first parentheses are for, if you will, order of operations. The 'result' of the set of parentheses surrounding the function definition is the function itself which, indeed, the second set of parentheses executes.

As to why it's useful, I'm not enough of a JavaScript wizard to have any idea. :P

Google has documented this https://developers.google.com/web/tools/chrome-devtools/console/console-write#styling_console_output_with_css

The CSS format specifier allows you to customize the display in the console. Start the string with the specifier and give the style you wish to apply as the second parameter.

One example:

console.log("%cThis will be formatted with large, blue text", "color: blue; font-size: x-large");

From a background script you can listen to the chrome.tabs.onUpdated event and check the property changeInfo.status on the callback. It can be loading or complete. If it is complete, do the action.

Example:

chrome.tabs.onUpdated.addListener( function (tabId, changeInfo, tab) {
  if (changeInfo.status == 'complete') {

    // do your things

  }
})

Because this will probably trigger on every tab completion, you can also check if the tab is active on its homonymous attribute, like this:

chrome.tabs.onUpdated.addListener( function (tabId, changeInfo, tab) {
  if (changeInfo.status == 'complete' && tab.active) {

    // do your things

  }
})

It's better to have a proper JSON format instead of directly using the one converted from XML.

[
  {
    "number": "2013-W45",
    "days": [
      {
        "dow": "1",
        "templateDay": "Monday",
        "jobs": [
          {
            "name": "Wakeup",
            "jobs": [
              {
                "name": "prepare breakfast",

              }
            ]
          },
          {
            "name": "work 9-5",

          }
        ]
      },
      {
        "dow": "2",
        "templateDay": "Tuesday",
        "jobs": [
          {
            "name": "Wakeup",
            "jobs": [
              {
                "name": "prepare breakfast",

              }
            ]
          }
        ]
      }
    ]
  }
]

This will make things much easier and easy to loop through.

Now you can write the loop as -

<div ng-repeat="week in myData">
   <div ng-repeat="day in week.days">
      {{day.dow}} - {{day.templateDay}}
      <b>Jobs:</b><br/> 
       <ul>
         <li ng-repeat="job in day.jobs"> 
           {{job.name}} 
         </li>
       </ul>
   </div>
</div>

I would recommend making Rock, Paper and Scissors objects. The objects would have the logic of both translating to/from Strings and also "knowing" what beats what. The Java enum is perfect for this.

public enum Type{

  ROCK, PAPER, SCISSOR;

  public static Type parseType(String value){
     //if /else logic here to return either ROCK, PAPER or SCISSOR

     //if value is not either, you can return null
  }
}

The parseType method can return null if the String is not a valid type. And you code can check if the value is null and if so, print "invalid try again" and loop back to re-read the Scanner.

Type person=null;

 while(person==null){
      System.out.println("Enter your play: "); 
      person= Type.parseType(scan.next());
      if(person ==null){
         System.out.println("invalid try again");
      }
 }

Furthermore, your type enum can determine what beats what by having each Type object know:

public enum Type{

    //...

    //each type will implement this method differently
    public abstract boolean beats(Type other);


}

each type will implement this method differently to see what beats what:

ROCK{

   @Override
   public boolean beats(Type other){            
        return other ==  SCISSOR;

   }
}

 ...

Then in your code

 Type person, computer;
   if (person.equals(computer)) 
   System.out.println("It's a tie!");
  }else if(person.beats(computer)){
     System.out.println(person+ " beats " + computer + "You win!!"); 
  }else{
     System.out.println(computer + " beats " + person+ "You lose!!");
  }

Plotly's R API might be useful for you. The graph below is here.

library(plotly)
#add username and key
p <- plotly(username="Username", key="API_KEY")
#generate data
x0 = rnorm(500)
x1 = rnorm(500)+1
#arrange your graph
data0 = list(x=x0,
         name = "Carrots",
         type='histogramx',
         opacity = 0.8)

data1 = list(x=x1,
         name = "Cukes",
         type='histogramx',
         opacity = 0.8)
#specify type as 'overlay'
layout <- list(barmode='overlay',
               plot_bgcolor = 'rgba(249,249,251,.85)')  
#format response, and use 'browseURL' to open graph tab in your browser.
response = p$plotly(data0, data1, kwargs=list(layout=layout))

url = response$url
filename = response$filename

browseURL(response$url)

Full disclosure: I'm on the team.

When you run git commit with no arguments, it will open your default editor to allow you to type a commit message. Saving the file and quitting the editor will make the commit.

It looks like your default editor is Vi or Vim. The reason "weird stuff" happens when you type is that Vi doesn't start in insert mode - you have to hit i on your keyboard first! If you don't want that, you can change it to something simpler, for example:

git config --global core.editor nano

Then you'll load the Nano editor (assuming it's installed!) when you commit, which is much more intuitive for users who've not used a modal editor such as Vi.

That text you see on your screen is just to remind you what you're about to commit. The lines are preceded by # which means they're comments, i.e. Git ignores those lines when you save your commit message. You don't need to type a message per file - just enter some text at the top of the editor's buffer.

To bypass the editor, you can provide a commit message as an argument, e.g.

git commit -m "Added foo to the bar"

There is no "standard" library function to do this. The standard (perhaps surprisingly) does not actually recognise the concept of a "keyboard", albeit it does have a standard for "console input".

There are various ways to achieve it on different operating systems (see herohuyongtao's solution) but it is not portable across all platforms that support keyboard input.

Remember that C++ (and C) are devised to be languages that can run on embedded systems that do not have keyboards. (Having said that, an embedded system might not have various other devices that the standard library supports).

This matter has been debated for a long time.

Iterator objects in python conform to the iterator protocol, which basically means they provide two methods: __iter__() and __next__().

• The __iter__ returns the iterator object and is implicitly called at the start of loops.

• The __next__() method returns the next value and is implicitly called at each loop increment. This method raises a StopIteration exception when there are no more value to return, which is implicitly captured by looping constructs to stop iterating.

Here's a simple example of a counter:

class Counter:
    def __init__(self, low, high):
        self.current = low - 1
        self.high = high

    def __iter__(self):
        return self

    def __next__(self): # Python 2: def next(self)
        self.current += 1
        if self.current < self.high:
            return self.current
        raise StopIteration


for c in Counter(3, 9):
    print(c)

This will print:

3
4
5
6
7
8

This is easier to write using a generator, as covered in a previous answer:

def counter(low, high):
    current = low
    while current < high:
        yield current
        current += 1

for c in counter(3, 9):
    print(c)

The printed output will be the same. Under the hood, the generator object supports the iterator protocol and does something roughly similar to the class Counter.

David Mertz's article, Iterators and Simple Generators, is a pretty good introduction.

You could opt for a pure CSS solution:

#hfont1 {
    transition: color 1s ease-in-out;
    -moz-transition: color 1s ease-in-out; /* FF 4 */
    -webkit-transition: color 1s ease-in-out; /* Safari & Chrome */
    -o-transition: color 1s ease-in-out; /* Opera */
}

Try like this:

select field1, array_to_string(array_agg(field2), ',')
from table1
group by field1;

I had this issue after converting my Write-Host cmdlets to Write-Information and I was missing quotes and parens around the parameters. The cmdlet signatures are evidently not the same.

Write-Host this is a good idea $here
Write-Information this is a good idea $here <=BAD

This is the cmdlet signature that corrected after spending 20-30 minutes digging down the function stack...

Write-Information ("this is a good idea $here") <=GOOD

First off, avoid using a cursor if at all possible. Here are some resources for rooting it out when it seems you can't do without:

There Must Be 15 Ways To Lose Your Cursors... part 1, Introduction

Row-By-Row Processing Without Cursor

That said, though, you may be stuck with one after all--I don't know enough from your question to be sure that either of those apply. If that's the case, you've got a different problem--the select statement for your cursor must be an actual SELECT statement, not an EXECUTE statement. You're stuck.

But see the answer from cmsjr (which came in while I was writing) about using a temp table. I'd avoid global cursors even more than "plain" ones....

This is more an object initialzation question more than a jpa question, both methods work and you can have both of them at the same time , usually if the data member value is ready before the instantiation you use the constructor parameters, if this value could be updated after the instantiation you should have a setter.

To set parameters to your HttpPostRequest you can use BasicNameValuePair, something like this :

    HttpClient httpclient;
    HttpPost httpPost;
    ArrayList<NameValuePair> postParameters;
    httpclient = new DefaultHttpClient();
    httpPost = new HttpPost("your login link");


    postParameters = new ArrayList<NameValuePair>();
    postParameters.add(new BasicNameValuePair("param1", "param1_value"));
    postParameters.add(new BasicNameValuePair("param2", "param2_value"));

    httpPost.setEntity(new UrlEncodedFormEntity(postParameters, "UTF-8"));

    HttpResponse response = httpclient.execute(httpPost);

I use the consolidate function, like so:

 element.transform.baseVal.consolidate()

The .e and .f values correspond to the x and y coordinates

I had the same issue with setting StatusCode and then Response.End in HandleUnauthorizedRequest method of AuthorizeAttribute

var ctx = filterContext.HttpContext;
ctx.Response.StatusCode = (int)HttpStatusCode.Forbidden;
ctx.Response.End();

If you are using .NET 4.5+, add this line before Response.StatusCode

filterContext.HttpContext.Response.SuppressFormsAuthenticationRedirect = true;

If you are using .NET 4.0, try SuppressFormsAuthenticationRedirectModule.

CheckBoxFor takes a bool, you're passing a List<CheckBoxes> to it. You'd need to do:

@for (int i = 0; i < Model.EmploymentType.Count; i++)
{
    @Html.CheckBoxFor(m => m.EmploymentType[i].Checked, new { id = "employmentType_" + i })
    @Html.HiddenFor(m => m.EmploymentType[i].Text)
    @Html.DisplayFor(m => m.EmploymentType[i].Text)
}

Notice I've added a HiddenFor for the Text property too, otherwise you'd lose that when you posted the form, so you wouldn't know which items you'd checked.

Edit, as shown in your comments, your EmploymentType list is null when the view is served. You'll need to populate that too, by doing this in your action method:

public ActionResult YourActionMethod()
{
    CareerForm model = new CareerForm();

    model.EmploymentType = new List<CheckBox>
    {
        new CheckBox { Text = "Fulltime" },
        new CheckBox { Text = "Partly" },
        new CheckBox { Text = "Contract" }
    };

    return View(model);
}

The no-op command in shell is : (colon).

if [ "$a" -ge 10 ]
then
    :
elif [ "$a" -le 5 ]
then
    echo "1"
else
    echo "2"
fi

From the bash manual:

: (a colon)
Do nothing beyond expanding arguments and performing redirections. The return status is zero.

I like

if ('string'[/^str/]) ...

VB6: Listview1.selecteditem

VB10: Listview1.FocusedItem.Text

Suppress the @JoinColumn(name="categoria") on the ID field of the Categoria class and I think it will work.

You should use a callback parameter:

function Typer(callback)
{
    var srcText = 'EXAMPLE ';
    var i = 0;
    var result = srcText[i];
    var interval = setInterval(function() {
        if(i == srcText.length - 1) {
            clearInterval(interval);
            callback();
            return;
        }
        i++;
        result += srcText[i].replace("\n", "<br />");
        $("#message").html(result);
    },
    100);
    return true;


}

function playBGM () {
    alert("Play BGM function");
    $('#bgm').get(0).play();
}

Typer(function () {
    playBGM();
});

// or one-liner: Typer(playBGM);

So, you pass a function as parameter (callback) that will be called in that if before return.

Also, this is a good article about callbacks.

For everyone if you still strugle with Refusing connection, here is my advice. Download XAMPP or other similar sw and just start MySQL. You dont have to run apache or other things just the MySQL.

Here is an example for toggling bold, underline, and italics.

   protected override bool ProcessCmdKey( ref Message msg, Keys keyData )
   {
      if ( ActiveControl is RichTextBox r )
      {
         if ( keyData == ( Keys.Control | Keys.B ) )
         {
            r.SelectionFont = new Font( r.SelectionFont, r.SelectionFont.Style ^ FontStyle.Bold ); // XOR will toggle
            return true;
         }
         if ( keyData == ( Keys.Control | Keys.U ) )
         {
            r.SelectionFont = new Font( r.SelectionFont, r.SelectionFont.Style ^ FontStyle.Underline ); // XOR will toggle
            return true;
         }
         if ( keyData == ( Keys.Control | Keys.I ) )
         {
            r.SelectionFont = new Font( r.SelectionFont, r.SelectionFont.Style ^ FontStyle.Italic ); // XOR will toggle
            return true;
         }
      }
      return base.ProcessCmdKey( ref msg, keyData );
   }

There's no built-in function for this.

Function SheetExists(SheetName As String, Optional wb As Excel.Workbook)
   Dim s As Excel.Worksheet
   If wb Is Nothing Then Set wb = ThisWorkbook
   On Error Resume Next
   Set s = wb.Sheets(SheetName)
   On Error GoTo 0
   SheetExists = Not s Is Nothing
End Function

If you use jQuery, u can do it like this:

<form action="example" method="post" id="loginform">
  ...
  <input id="btnin" type="button" value="login"/>
  <input id="btnreg" type="button" value="regist"/>
</form>

And js will be:

$("#btnin").click(function(){
   $("#loginform").attr("action", "user_login");
   $("#loginform").submit();
}
$("#btnreg").click(function(){
   $("#loginform").attr("action", "user_regist");
   $("#loginform").submit();
}

I had the same problem. I decided in a very unexpected way. Just opened the command line as an administrator. And then typed:

pip install numpy

Nitin is correct - the issue is actually in the MDB2 code.

According to Replacement for PEAR: MDB2 on PHP 5.3 you can update to the SVN version of MDB2 for a version which is PHP5.3 compatible.

As that answer was given in March 2010, and http://pear.php.net/package/MDB2/ shows a release some months later, I expect the current version of MDB2 will solve the issue also.

Just add this below JS file

<script type="text/javascript">
    $(document).ready(function () {
        $('your input's id or class with # or .').datepicker({
            format: "dd/mm/yyyy"
        });
    });
</script>

I'm not able to comment divega's post, but among the different solutions presented here, divega's solution produces the best SQL. Both performance wise and length wise. I just checked with SQL Server Profiler and by looking at the execution plan (with "SET STATISTICS PROFILE ON").

along with these two variants, there is also jade.renderFile which generates html that need not be passed to the client.

usage-

var jade = require('jade');

exports.getJson = getJson;

function getJson(req, res) {
    var html = jade.renderFile('views/test.jade', {some:'json'});
    res.send({message: 'i sent json'});
}

getJson() is available as a route in app.js.

<style>
.row-2 UL LI A
{
  margin-top: 10px;  /* or whatever amount you need it to move down */
}
</style>

I know this is quite an old question -

A = [[1, 2, 3],
     [4, 5, 6],
     [7, 8, 9]]

Let's say, you want to extract the first 2 rows and first 3 columns

A_NEW = A[0:2, 0:3]
A_NEW = [[1, 2, 3],
         [4, 5, 6]]

Understanding the syntax

A_NEW = A[start_index_row : stop_index_row, 
          start_index_column : stop_index_column)]

If one wants row 2 and column 2 and 3

A_NEW = A[1:2, 1:3]

Reference the numpy indexing and slicing article - Indexing & Slicing

I prefer writing small one liners for each replace I have to do instead of making a more generic and complex code. E.g.:

This replaces all underscores with hyphens in any non-hidden file in the current directory

import os
[os.rename(f, f.replace('_', '-')) for f in os.listdir('.') if not f.startswith('.')]

Modal Window using ExtJS approach.

In Main Window

You have to remove the semicolon in the css rule string:

$(this).parent().css("background", "url(/images/r-srchbg_white.png) no-repeat");

I have had similar issues with Homestead and just provisioning the box worked for me. So you should try this:

vagrant provision

There's actually quite a simple native method for this:

if( $('#myfav')[0].hasChildNodes() ) { ... }

Note that this also includes simple text nodes, so it will be true for a <div>text</div>.

to_char actually lets you pull out the Year and month in one fell swoop!

select to_char(date('2014-05-10'),'Mon-YY') as year_month; --'May-14'
select to_char(date('2014-05-10'),'YYYY-MM') as year_month; --'2014-05'

or in the case of the user's example above:

select to_char(date,'YY-Mon') as year_month
       sum("Sales") as "Sales"
from some_table
group by 1;

Could this exception be thrown during an unfinished transaction, where your application is attempting to create an entity with a duplicate field to the identifier you are using to try find a single entity?

In this case the new (duplicate) entity will not be visible in the database as the transaction won't have, and will never be committed to the db. The exception will still be thrown however.

I just faced this issue, doing some research I found that the data values has to be sended as URLSearchParams, I do it like this:

getAuthToken: async () => {
const data = new URLSearchParams();
data.append('grant_type', 'client_credentials');
const fetchAuthToken = await axios({
  url: `${PAYMENT_URI}${PAYMENT_GET_TOKEN_PATH}`,
  method: 'POST',
  auth: {
    username: PAYMENT_CLIENT_ID,
    password: PAYMENT_SECRET,
  },
  headers: {
    Accept: 'application/json',
    'Accept-Language': 'en_US',
    'Content-Type': 'application/x-www-form-urlencoded',
    'Access-Control-Allow-Origin': '*',
  },
  data,
  withCredentials: true,
});
return fetchAuthToken;

},

Well, your code is not reproducible so we will never know for sure, but this is what help('break')says:

break breaks out of a for, while or repeat loop; control is transferred to the first statement outside the inner-most loop.

So yes, break only breaks the current loop. You can also see it in action with e.g.:

for (i in 1:10)
{
    for (j in 1:10)
    {
        for (k in 1:10)
        {
            cat(i," ",j," ",k,"\n")
            if (k ==5) break
        }   
    }
}

Exception code c0000005 is the code for an access violation. That means that your program is accessing (either reading or writing) a memory address to which it does not have rights. Most commonly this is caused by:

• Accessing a stale pointer. That is accessing memory that has already been deallocated. Note that such stale pointer accesses do not always result in access violations. Only if the memory manager has returned the memory to the system do you get an access violation.
• Reading off the end of an array. This is when you have an array of length N and you access elements with index >=N.

To solve the problem you'll need to do some debugging. If you are not in a position to get the fault to occur under your debugger on your development machine you should get a crash dump file and load it into your debugger. This will allow you to see where in the code the problem occurred and hopefully lead you to the solution. You'll need to have the debugging symbols associated with the executable in order to see meaningful stack traces.

As far as I know PKCS#12 is just a certificate/public/private key store. If you extracted a public key from PKCS#12 file, OpenSSH should be able to use it as long as it was extracted in PEM format. You probably already know that you also need a corresponding private key (also in PEM) in order to use it for ssh-public-key authentication.

Using data.table

 library(data.table)
 setDT(dat)[, .N, keyby=ID] #(Using @Paul Hiemstra's `dat`)

Or using dplyr 0.3

 res <- count(dat, ID)
 head(res)
 #Source: local data frame [6 x 2]

 #  ID n
 #1  a 2
 #2  b 3
 #3  c 3
 #4  d 3
 #5  e 2
 #6  f 4

Or

  dat %>% 
      group_by(ID) %>% 
      tally()

Or

  dat %>% 
      group_by(ID) %>%
      summarise(n=n())

Check this link . You were missing . before myButton. It was a small error. :)

.myButton{
    background:url(./images/but.png) no-repeat;
    cursor:pointer;
    border:none;
    width:100px;
    height:100px;
}

.myButton:active  /* use Dot here */
{   
    background:url(./images/but2.png) no-repeat;
}

The default behavior is:

1. If the parameter is a primitive type (int, bool, double, ...), Web API tries to get the value from the URI of the HTTP request.

2. For complex types (your own object, for example: Person), Web API tries to read the value from the body of the HTTP request.

So, if you have:

• a primitive type in the URI, or
• a complex type in the body

...then you don't have to add any attributes (neither [FromBody] nor [FromUri]).

But, if you have a primitive type in the body, then you have to add [FromBody] in front of your primitive type parameter in your WebAPI controller method. (Because, by default, WebAPI is looking for primitive types in the URI of the HTTP request.)

Or, if you have a complex type in your URI, then you must add [FromUri]. (Because, by default, WebAPI is looking for complex types in the body of the HTTP request by default.)

Primitive types:

public class UsersController : ApiController
{
    // api/users
    public HttpResponseMessage Post([FromBody]int id)
    {

    }
    // api/users/id
    public HttpResponseMessage Post(int id)
    {

    }       
}

Complex types:

public class UsersController : ApiController
{       
    // api/users
    public HttpResponseMessage Post(User user)
    {

    }

    // api/users/user
    public HttpResponseMessage Post([FromUri]User user)
    {

    }       
}

This works as long as you send only one parameter in your HTTP request. When sending multiple, you need to create a custom model which has all your parameters like this:

public class MyModel
{
    public string MyProperty { get; set; }
    public string MyProperty2 { get; set; }
}

[Route("search")]
[HttpPost]
public async Task<dynamic> Search([FromBody] MyModel model)
{
    // model.MyProperty;
    // model.MyProperty2;
}

From Microsoft's documentation for parameter binding in ASP.NET Web API:

When a parameter has [FromBody], Web API uses the Content-Type header to select a formatter. In this example, the content type is "application/json" and the request body is a raw JSON string (not a JSON object). At most one parameter is allowed to read from the message body.

This should work:

public HttpResponseMessage Post([FromBody] string name) { ... }

This will not work:

// Caution: This won't work!    
public HttpResponseMessage Post([FromBody] int id, [FromBody] string name) { ... }

The reason for this rule is that the request body might be stored in a non-buffered stream that can only be read once.

you can not do it in this way

Use the following instead

typedef struct
{
   int id;
   char* name;
}employee;

employee emp = {
.id = 0, 
.name = "none"
};

You can use macro to define and initialize your instances. this will make easiier to you each time you want to define new instance and initialize it.

typedef struct
{
   int id;
   char* name;
}employee;

#define INIT_EMPLOYEE(X) employee X = {.id = 0, .name ="none"}

and in your code when you need to define new instance with employee type, you just call this macro like:

INIT_EMPLOYEE(emp);

It is called favicon.ico and you can generate it from this site.

You don't need a third party package to get this information. pypi provides simple JSON feeds for all packages under

https://pypi.org/pypi/{PKG_NAME}/json

Here's some Python code using only the standard library which gets all versions.

import json
import urllib2
from distutils.version import StrictVersion

def versions(package_name):
    url = "https://pypi.org/pypi/%s/json" % (package_name,)
    data = json.load(urllib2.urlopen(urllib2.Request(url)))
    versions = data["releases"].keys()
    versions.sort(key=StrictVersion)
    return versions

print "\n".join(versions("scikit-image"))

That code prints (as of Feb 23rd, 2015):

0.7.2
0.8.0
0.8.1
0.8.2
0.9.0
0.9.1
0.9.2
0.9.3
0.10.0
0.10.1

A simple way to achieve what you want:

import cv2
s_img = cv2.imread("smaller_image.png")
l_img = cv2.imread("larger_image.jpg")
x_offset=y_offset=50
l_img[y_offset:y_offset+s_img.shape[0], x_offset:x_offset+s_img.shape[1]] = s_img

Update

I suppose you want to take care of the alpha channel too. Here is a quick and dirty way of doing so:

s_img = cv2.imread("smaller_image.png", -1)

y1, y2 = y_offset, y_offset + s_img.shape[0]
x1, x2 = x_offset, x_offset + s_img.shape[1]

alpha_s = s_img[:, :, 3] / 255.0
alpha_l = 1.0 - alpha_s

for c in range(0, 3):
    l_img[y1:y2, x1:x2, c] = (alpha_s * s_img[:, :, c] +
                              alpha_l * l_img[y1:y2, x1:x2, c])

The problem is the import of ProjectsListComponent in your ProjectsModule. You should not import that, but add it to the export array, if you want to use it outside of your ProjectsModule.

Other issues are your project routes. You should add these to an exportable variable, otherwise it's not AOT compatible. And you should -never- import the BrowserModule anywhere else but in your AppModule. Use the CommonModule to get access to the *ngIf, *ngFor...etc directives:

@NgModule({
  declarations: [
     ProjectsListComponent
  ],
  imports: [
    CommonModule,
    RouterModule.forChild(ProjectRoutes)
  ],
  exports: [
     ProjectsListComponent
  ]
})

export class ProjectsModule {}

project.routes.ts

export const ProjectRoutes: Routes = [
      { path: 'projects', component: ProjectsListComponent }
]

You have to add the targeted map :

var markers = [
            {
            "title": 'This is title',
            "lat": '-37.801578',
            "lng": '145.060508',
            "map":  map,
            "icon": 'http://google-maps-icons.googlecode.com/files/sailboat-tourism.png',
            "description": 'Vikash Rathee. <strong> This is test Description</strong> <br/><a href="http://www.pricingindia.in/pincode.aspx">Pin Code by 

City</a>'
            }
];

I found two plugins for that. One loads the values from a file and the other lets you configure the values in the job configuration screen.

Envfile Plugin — This plugin enables you to set environment variables via a file. The file's format must be the standard Java property file format.

EnvInject Plugin — This plugin makes it possible to add environment variables and execute a setup script in order to set up an environment for the Job.

Those integer types are all defined in stdint.h

I had the same issue but fixed just after running these commands:

flutter channel dev
flutter doctor
flutter channel master
flutter doctor

I would use ConfigurationManager.OpenMappedExeConfiguration.

If You want to find a specific object via search function just try something like this:

    function findArray(value){

        let countLayer = dataLayer.length;
        for(var x = 0 ; x < countLayer ; x++){

            if(dataLayer[x].user){
                let newArr = dataLayer[x].user;
                let data = newArr[value];
                return data;
            }

        }

        return null;

    }

    findArray("id");

This is an example object:

layerObj = {
    0: { gtm.start :1232542, event: "gtm.js"},
    1: { event: "gtm.dom", gtm.uniqueEventId: 52},
    2: { visitor id: "abcdef2345"},
    3: { user: { id: "29857239", verified: "Null", user_profile: "Personal", billing_subscription: "True", partners_user: "adobe"}
}

Code will iterate and find the "user" array and will search for the object You seek inside.

My problem was when the array index changed every window refresh and it was either in 3rd or second array, but it does not matter.

Worked like a charm for Me!

In Your example it is a bit shorter:

function findArray(value){

    let countLayer = Object.length;
    for(var x = 0 ; x < countLayer ; x++){

        if(Object[x].dinner === value){
            return Object[x];
        }

    }

    return null;

}

findArray('sushi');

pip install --user <package name> (no sudo needed) worked for me for a very similar problem.

char word[length];
char *rtnPtr = word;
...
return rtnPtr;

This is not good. You are returning a pointer to an automatic (scoped) variable, which will be destroyed when the function returns. The pointer will be left pointing at a destroyed variable, which will almost certainly produce "strange" results (undefined behaviour).

You should be allocating the string with malloc (e.g. char *rtnPtr = malloc(length)), then freeing it later in main.

I ended up packaging this into an extension method so (1) I could generate the label and radio at once and (2) so I didn't have to fuss with specifying my own IDs:

public static class HtmlHelperExtensions
{
    public static MvcHtmlString RadioButtonAndLabelFor<TModel, TProperty>(this HtmlHelper<TModel> self, Expression<Func<TModel, TProperty>> expression, bool value, string labelText)
    {
        // Retrieve the qualified model identifier
        string name = ExpressionHelper.GetExpressionText(expression);
        string fullName = self.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName(name);

        // Generate the base ID
        TagBuilder tagBuilder = new TagBuilder("input");
        tagBuilder.GenerateId(fullName);
        string idAttr = tagBuilder.Attributes["id"];

        // Create an ID specific to the boolean direction
        idAttr = String.Format("{0}_{1}", idAttr, value);

        // Create the individual HTML elements, using the generated ID
        MvcHtmlString radioButton = self.RadioButtonFor(expression, value, new { id = idAttr });
        MvcHtmlString label = self.Label(idAttr, labelText);

        return new MvcHtmlString(radioButton.ToHtmlString() + label.ToHtmlString());
    }
}

Usage:

@Html.RadioButtonAndLabelFor(m => m.IsMarried, true, "Yes, I am married")

It should also be noted that if you have buttons grouped together on your user form that it can link it to a different button in the group despite the one you intended being clicked.

I would like to point out that the solutions given above do not "just work" with non-trivial queries. One issue I came across were more complicated types, such as pgsql ARRAYs causing issues. I did find a solution that for me, did just work even with pgsql ARRAYs:

The linked code seems to be based on an older version of SQLAlchemy. You'll get an error saying that the attribute _mapper_zero_or_none doesn't exist. Here's an updated version that will work with a newer version, you simply replace _mapper_zero_or_none with bind. Additionally, this has support for pgsql arrays:

I encountered this problem today as well. I am using Windows and the system language by default is Chinese. Hence, someone may encounter this Unicode error similarly. Simply add encoding = 'utf-8':

with open("test.html", "r", encoding='utf-8') as f:
    text= f.read()

StewieFG suggestion is valid but if you want to add the recipient name use this, with what Marco has posted above but is email address first and display name second:

msg.To.Add(new MailAddress("[email protected]","Your name 1"));
msg.To.Add(new MailAddress("[email protected]","Your name 2"));

Add poster="placeholder.png" to the video tag.

Does that work?

It looks like you are missing including the IOBluetooth.framework in your project. You can add it by:

• Clicking on your project in the upper left of the left pane (the blue icon).

• In the middle pane, click on the Build Phases tab.

• Under "Link Binary With Libraries", click on the plus button.

• Find the IOBluetooth.framework from the list and hit Add.

This will make sure that the IOBluetooth.framework definitions are found by the linker. You can see that the framework is a member of your target by clicking on the framework in the left pane and seeing the framework's target membership in the right pane (note I've moved the framework under the Frameworks group for organization purposes):

Initially, check the type of compression with the below command: file <file_name> If the output is a Posix compressed file, use the below command to uncompress: tar xvf <file_name>

Making use of JavaScripts short-circuit evaluation. If el.shouldBeProcessed returns true, doSomeLengthyOperation

A tar.gz is a tar file inside a gzip file, so 1st you must unzip the gzip file with gunzip -d filename.tar.gz , and then use tar to untar it. However, since gunzip says it isn't in gzip format, you can see what format it is in with file filename.tar.gz, and use the appropriate program to open it.

Simple program to understand difference between continue and break

When continue is used

    public static void main(String[] args) {
    System.out.println("HelloWorld");
    for (int i = 0; i < 5; i++){
        System.out.println("Start For loop i = " + i);
        if(i==2){
            System.out.println("Inside if Statement for i = "+i);
           continue;
        }
        System.out.println("End For loop i = " + i);
    }
    System.out.println("Completely out of For loop");
}


OutPut:
HelloWorld
Start For loop i = 0
End For loop i = 0
Start For loop i = 1
End For loop i = 1
Start For loop i = 2
Inside if Statement for i = 2
Start For loop i = 3
End For loop i = 3
Start For loop i = 4
End For loop i = 4
Completely out of For loop

When break is used

public static void main(String[] args) {
    System.out.println("HelloWorld");
    for (int i = 0; i < 5; i++){
        System.out.println("Start For loop i = " + i);
        if(i==2){
            System.out.println("Inside if Statement for i = "+i);
           break;
        }
        System.out.println("End For loop i = " + i);
    }
    System.out.println("Completely out of For loop");
}

Output:
HelloWorld
Start For loop i = 0
End For loop i = 0
Start For loop i = 1
End For loop i = 1
Start For loop i = 2
Inside if Statement for i = 2
Completely out of For loop

Update 2020: HTML Solution

Since HTML 5 is so much developed and almost all major browser supporting it. So now a much cleaner approach is to use HTML5 data attributes (maxx777 provided a PHP solution I am using the simple HTML). For non-numeric data as in our scenario, we can use data-sort or data-order attribute and assign a sortable value to it.

HTML

<td data-sort='YYYYMMDD'>DD/MM/YYYY</td>

Here is working HTML solution

jQuery Solution

Here is working jQuery solution.

jQuery.extend( jQuery.fn.dataTableExt.oSort, {
"date-uk-pre": function ( a ) {
    var ukDatea = a.split('/');
    return (ukDatea[2] + ukDatea[1] + ukDatea[0]) * 1;
},

"date-uk-asc": function ( a, b ) {
    return ((a < b) ? -1 : ((a > b) ? 1 : 0));
},

"date-uk-desc": function ( a, b ) {
    return ((a < b) ? 1 : ((a > b) ? -1 : 0));
}
} );
 

Add the above code to script and set the specific column with Date values with { "sType": "date-uk" } and others as null, see below:

$(document).ready(function() {
    $('#example').dataTable( {
        "aoColumns": [
            null,
            null,
            null,
            null,
            { "sType": "date-uk" },
            null
        ]
    });
    });

• utf8_bin compares the bits blindly. No case folding, no accent stripping.
• utf8_general_ci compares one byte with one byte. It does case folding and accent stripping, but no 2-character comparisions: ij is not equal ? in this collation.
• utf8_*_ci is a set of language-specific rules, but otherwise like unicode_ci. Some special cases: Ç, C, ch, ll
• utf8_unicode_ci follows an old Unicode standard for comparisons. ij=?, but ae != æ
• utf8_unicode_520_ci follows an newer Unicode standard. ae = æ

See collation chart for details on what is equal to what in various utf8 collations.

utf8, as defined by MySQL is limited to the 1- to 3-byte utf8 codes. This leaves out Emoji and some of Chinese. So you should really switch to utf8mb4 if you want to go much beyond Europe.

The above points apply to utf8mb4, after suitable spelling change. Going forward, utf8mb4 and utf8mb4_unicode_520_ci are preferred.

• utf16 and utf32 are variants on utf8; there is virtually no use for them.
• ucs2 is closer to "Unicode" than "utf8"; there is virtually no use for it.

import datetime

timestamp = datetime.datetime.fromtimestamp(1500000000)

print(timestamp.strftime('%Y-%m-%d %H:%M:%S'))

This will give the output:

2017-07-14 08:10:00

Trying to make this as short and simple as possible. Creates directory if it doesn't exist, and then returns the desired file:

/** Creates parent directories if necessary. Then returns file */
private static File fileWithDirectoryAssurance(String directory, String filename) {
    File dir = new File(directory);
    if (!dir.exists()) dir.mkdirs();
    return new File(directory + "/" + filename);
}

In macOS 10.14 this issue may also occur if you have two or more versions installed. If you like xCode GUI you can do it by going into preferences - CMD + ,, selecting Locations tab and choosing version of Command Line Tools. Please refer to the attached print screen.

You have to do something like:

case 1:
case 2:
case 3:
//do stuff
break;

This is a two-step process:

1. you need to create a login to SQL Server for that user, based on its Windows account

   CREATE LOGIN [<domainName>\<loginName>] FROM WINDOWS;
   

2. you need to grant this login permission to access a database:

   USE (your database)
   CREATE USER (username) FOR LOGIN (your login name)
   

Once you have that user in your database, you can give it any rights you want, e.g. you could assign it the db_datareader database role to read all tables.

USE (your database)
EXEC sp_addrolemember 'db_datareader', '(your user name)'

You can use Mockito.isA() for that:

import static org.mockito.Matchers.isA;
import static org.mockito.Mockito.verify;

verify(bar).doStuff(isA(Foo[].class));

http://site.mockito.org/mockito/docs/current/org/mockito/Matchers.html#isA(java.lang.Class)

You have to select the option in ArrayAdapter:

ArrayAdapter<String> adapter = new ArrayAdapter<String>
    (this, android.R.layout.simple_list_item_single_choice, countries);

I personally found this easier to remember, as these 2 terms always confused me as beginner to web development.

There are several ways rsync compares files -- the authoritative source is the rsync algorithm description: https://www.andrew.cmu.edu/course/15-749/READINGS/required/cas/tridgell96.pdf. The wikipedia article on rsync is also very good.

For local files, rsync compares metadata and if it looks like it doesn't need to copy the file because size and timestamp match between source and destination it doesn't look further. If they don't match, it cp's the file. However, what if the metadata do match but files aren't actually the same? Then rsync probably didn't do what you intended.

Files that are the same size may still have changed. One simple example is a text file where you correct a typo -- like changing "teh" to "the". The file size is the same, but the corrected file will have a newer timestamp. --size-only says "don't look at the time; if size matches assume files match", which would be the wrong choice in this case.

On the other hand, suppose you accidentally did a big cp -r A B yesterday, but you forgot to preserve the time stamps, and now you want to do the operation in reverse rsync B A. All those files you cp'ed have yesterday's time stamp, even though they weren't really modified yesterday, and rsync will by default end up copying all those files, and updating the timestamp to yesterday too. --size-only may be your friend in this case (modulo the example above).

--ignore-times says to compare the files regardless of whether the files have the same modify time. Consider the typo example above, but then not only did you correct the typo but you used touch to make the corrected file have the same modify time as the original file -- let's just say you're sneaky that way. Well --ignore-times will do a diff of the files even though the size and time match.

You can use the code below to solve the problem or download demo here

Create two functions to handle each.

First, the canvas is drawn and the images are drawn on top of each other from point (0,0)

On button click

public void buttonMerge(View view) {

        Bitmap bigImage = BitmapFactory.decodeResource(getResources(), R.drawable.img1);
        Bitmap smallImage = BitmapFactory.decodeResource(getResources(), R.drawable.img2);
        Bitmap mergedImages = createSingleImageFromMultipleImages(bigImage, smallImage);

        img.setImageBitmap(mergedImages);
    }

Function to create an overlay.

private Bitmap createSingleImageFromMultipleImages(Bitmap firstImage, Bitmap secondImage){

    Bitmap result = Bitmap.createBitmap(firstImage.getWidth(), firstImage.getHeight(), firstImage.getConfig());
    Canvas canvas = new Canvas(result);
    canvas.drawBitmap(firstImage, 0f, 0f, null);
    canvas.drawBitmap(secondImage, 10, 10, null);
    return result;

During the creation of S3Client you can specify the endpoint mapping to a particular region. If default of s3.amazonaws.com then bucket will be created in us-east-1 which is North Virginia.

More details on S3 endpoints and regions in AWS docs: http://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region.

So, always make sure about the endpoint/region while creating the S3Client and access S3 resouces using the same client in the same region.

If the bucket is created from AWS S3 Console, then check the region from the console for that bucket then create a S3 Client in that region using the endpoint details mentioned in the above link.

len(self.table) checks for the length of the array, so you can use if-statements to find out if the length of the list is greater than 0 (not empty):

Python 2:

if len(self.table) > 0:
    #Do code here

Python 3:

if(len(self.table) > 0):
    #Do code here

It's also possible to use

if self.table:
    #Execute if self.table is not empty
else:
    #Execute if self.table is empty

to see if the list is not empty.

open AAAA,"/filepath/filename.txt";
my @array = <AAAA>; # read the file into an array of lines
close AAAA;

Just wrap your WebElement into Select Object as shown below

Select dropdown = new Select(driver.findElement(By.id("identifier")));

Once this is done you can select the required value in 3 ways. Consider an HTML file like this

<html>
<body>
<select id = "designation">
<option value = "MD">MD</option>
<option value = "prog"> Programmer </option>
<option value = "CEO"> CEO </option>
</option>
</select>
<body>
</html>

Now to identify dropdown do

Select dropdown = new Select(driver.findElement(By.id("designation")));

To select its option say 'Programmer' you can do

dropdown.selectByVisibleText("Programmer ");

or

dropdown.selectByIndex(1);

or

 dropdown.selectByValue("prog");

All you need is a control that you can set the text of, and an UpdatePanel if the exception occurs during a postback.

If occurs during a postback: markup:

<ajax:UpdatePanel id="ErrorUpdatePanel" runat="server" UpdateMode="Coditional">
<ContentTemplate>
<asp:TextBox id="ErrorTextBox" runat="server" />
</ContentTemplate>
</ajax:UpdatePanel>

code:

try
{
do something
}

catch(YourException ex)
{
this.ErrorTextBox.Text = ex.Message;
this.ErrorUpdatePanel.Update();
}

As mentioned in the accepted answer, this error is usually caused when the API returns data in a format, say object, instead of in an array.

If no existing answer here cuts it for you, you might want to convert the data you are dealing with into an array with something like:

let madeArr = Object.entries(initialApiResponse)

The resulting madeArr with will be an array of arrays.

This works fine for me whenever I encounter this error.

for jQuery 1.6 or higher:

if ($('input.checkbox_check').prop('checked')) {
    //blah blah
}

the cross-browser-compatible way to determine if a checkbox is checked is to use the property https://api.jquery.com/prop/

string = ""
name = raw_input() #The value at the field
length = input() #the length of the field
string += name
string += " "*(length-len(name)) # Add extra spaces

This will add the number of spaces needed, provided the field has length >= the length of the name provided

For all struggling around with the #selector in Swift 3 or Swift 4, here a full code example:

// WE NEED A CLASS THAT SHOULD RECEIVE NOTIFICATIONS
    class MyReceivingClass {

    // ---------------------------------------------
    // INIT -> GOOD PLACE FOR REGISTERING
    // ---------------------------------------------
    init() {
        // WE REGISTER FOR SYSTEM NOTIFICATION (APP WILL RESIGN ACTIVE)

        // Register without parameter
        NotificationCenter.default.addObserver(self, selector: #selector(MyReceivingClass.handleNotification), name: .UIApplicationWillResignActive, object: nil)

        // Register WITH parameter
        NotificationCenter.default.addObserver(self, selector: #selector(MyReceivingClass.handle(withNotification:)), name: .UIApplicationWillResignActive, object: nil)
    }

    // ---------------------------------------------
    // DE-INIT -> LAST OPTION FOR RE-REGISTERING
    // ---------------------------------------------
    deinit {
        NotificationCenter.default.removeObserver(self)
    }

    // either "MyReceivingClass" must be a subclass of NSObject OR selector-methods MUST BE signed with '@objc'

    // ---------------------------------------------
    // HANDLE NOTIFICATION WITHOUT PARAMETER
    // ---------------------------------------------
    @objc func handleNotification() {
        print("RECEIVED ANY NOTIFICATION")
    }

    // ---------------------------------------------
    // HANDLE NOTIFICATION WITH PARAMETER
    // ---------------------------------------------
    @objc func handle(withNotification notification : NSNotification) {
        print("RECEIVED SPECIFIC NOTIFICATION: \(notification)")
    }
}

In this example we try to get POSTs from AppDelegate (so in AppDelegate implement this):

// ---------------------------------------------
// WHEN APP IS GOING TO BE INACTIVE
// ---------------------------------------------
func applicationWillResignActive(_ application: UIApplication) {

    print("POSTING")

    // Define identifiyer
    let notificationName = Notification.Name.UIApplicationWillResignActive

    // Post notification
    NotificationCenter.default.post(name: notificationName, object: nil)
}

I wrote this to compare the results of a pretty nasty view I ported from Oracle to SQL Server. It creates a pair of temp tables, #DataVariances and #SchemaVariances, with differences in (you guessed it) the data in the tables and the schema of the tables themselves.

It requires both tables have a primary key, but you could drop it into tempdb with an identity column if the source tables don't have one.

For SQL Server 2012 onwards it could be easy:

SELECT id, SomeNumt, sum(SomeNumt) OVER (ORDER BY id) as CumSrome FROM @t

because ORDER BY clause for SUM by default means RANGE UNBOUNDED PRECEDING AND CURRENT ROW for window frame ("General Remarks" at https://msdn.microsoft.com/en-us/library/ms189461.aspx)

This is a very different style of programming, but I always try to rewrite things that looked like

bar = None
if foo():
    bar = "Baz"

if bar is None:
    bar = "Quux"

into just:

if foo():
    bar = "Baz"
else:
    bar = "Quux"

That is to say, I try hard to avoid a situation where some code paths define variables but others don't. In my code, there is never a path which causes an ambiguity of the set of defined variables (In fact, I usually take it a step further and make sure that the types are the same regardless of code path). It may just be a matter of personal taste, but I find this pattern, though a little less obvious when I'm writing it, much easier to understand when I'm later reading it.

I am not very sure whether it will make any difference in performance of my API.

Bear in mind that the primary benefit of asynchronous code on the server side is scalability. It won't magically make your requests run faster. I cover several "should I use async" considerations in my article on async ASP.NET.

I think your use case (calling other APIs) is well-suited for asynchronous code, just bear in mind that "asynchronous" does not mean "faster". The best approach is to first make your UI responsive and asynchronous; this will make your app feel faster even if it's slightly slower.

As far as the code goes, this is not asynchronous:

public Task<BackOfficeResponse<List<Country>>> ReturnAllCountries()
{
  var response = _service.Process<List<Country>>(BackOfficeEndpoint.CountryEndpoint, "returnCountries");
  return Task.FromResult(response);
}

You'd need a truly asynchronous implementation to get the scalability benefits of async:

public async Task<BackOfficeResponse<List<Country>>> ReturnAllCountriesAsync()
{
  return await _service.ProcessAsync<List<Country>>(BackOfficeEndpoint.CountryEndpoint, "returnCountries");
}

Or (if your logic in this method really is just a pass-through):

public Task<BackOfficeResponse<List<Country>>> ReturnAllCountriesAsync()
{
  return _service.ProcessAsync<List<Country>>(BackOfficeEndpoint.CountryEndpoint, "returnCountries");
}

Note that it's easier to work from the "inside out" rather than the "outside in" like this. In other words, don't start with an asynchronous controller action and then force downstream methods to be asynchronous. Instead, identify the naturally asynchronous operations (calling external APIs, database queries, etc), and make those asynchronous at the lowest level first (Service.ProcessAsync). Then let the async trickle up, making your controller actions asynchronous as the last step.

And under no circumstances should you use Task.Run in this scenario.

If you simply want to know if the sets are equal, the equals method on AbstractSet is implemented roughly as below:

    public boolean equals(Object o) {
        if (o == this)
            return true;
        if (!(o instanceof Set))
            return false;
        Collection c = (Collection) o;
        if (c.size() != size())
            return false;
        return containsAll(c);
    }

Note how it optimizes the common cases where:

• the two objects are the same
• the other object is not a set at all, and
• the two sets' sizes are different.

After that, containsAll(...) will return false as soon as it finds an element in the other set that is not also in this set. But if all elements are present in both sets, it will need to test all of them.

The worst case performance therefore occurs when the two sets are equal but not the same objects. That cost is typically O(N) or O(NlogN) depending on the implementation of this.containsAll(c).

And you get close-to-worst case performance if the sets are large and only differ in a tiny percentage of the elements.

UPDATE

If you are willing to invest time in a custom set implementation, there is an approach that can improve the "almost the same" case.

The idea is that you need to pre-calculate and cache a hash for the entire set so that you could get the set's current hashcode value in O(1). Then you can compare the hashcode for the two sets as an acceleration.

How could you implement a hashcode like that? Well if the set hashcode was:

• zero for an empty set, and
• the XOR of all of the element hashcodes for a non-empty set,

then you could cheaply update the set's cached hashcode each time you added or removed an element. In both cases, you simply XOR the element's hashcode with the current set hashcode.

Of course, this assumes that element hashcodes are stable while the elements are members of sets. It also assumes that the element classes hashcode function gives a good spread. That is because when the two set hashcodes are the same you still have to fall back to the O(N) comparison of all elements.

You could take this idea a bit further ... at least in theory.

WARNING - This is highly speculative. A "thought experiment" if you like.

Suppose that your set element class has a method to return a crypto checksums for the element. Now implement the set's checksums by XORing the checksums returned for the elements.

What does this buy us?

Well, if we assume that nothing underhand is going on, the probability that any two unequal set elements have the same N-bit checksums is 2^-N. And the probability 2 unequal sets have the same N-bit checksums is also 2^-N. So my idea is that you can implement equals as:

    public boolean equals(Object o) {
        if (o == this)
            return true;
        if (!(o instanceof Set))
            return false;
        Collection c = (Collection) o;
        if (c.size() != size())
            return false;
        return checksums.equals(c.checksums);
    }

Under the assumptions above, this will only give you the wrong answer once in 2^-N time. If you make N large enough (e.g. 512 bits) the probability of a wrong answer becomes negligible (e.g. roughly 10^-150).

The downside is that computing the crypto checksums for elements is very expensive, especially as the number of bits increases. So you really need an effective mechanism for memoizing the checksums. And that could be problematic.

And the other downside is that a non-zero probability of error may be unacceptable no matter how small the probability is. (But if that is the case ... how do you deal with the case where a cosmic ray flips a critical bit? Or if it simultaneously flips the same bit in two instances of a redundant system?)

You could also just put the first SELECT in a subquery. Since most optimizers will fold it into a constant anyway, there should not be a performance hit on this.

Incidentally, since you are using a predicate like this:

CONVERT(...) = CONVERT(...)

that predicate expression cannot be optimized properly or use indexes on the columns reference by the CONVERT() function.

Here is one way to make the original query somewhat better:

DECLARE @ooDate datetime
SELECT @ooDate = OO.Date FROM OLAP.OutageHours AS OO where OO.OutageID = 1

SELECT 
  COUNT(FF.HALID)
FROM
  Outages.FaultsInOutages AS OFIO 
  INNER JOIN Faults.Faults as FF ON 
    FF.HALID = OFIO.HALID 
WHERE
  FF.FaultDate >= @ooDate AND
  FF.FaultDate < DATEADD(day, 1, @ooDate) AND
  OFIO.OutageID = 1

This version could leverage in index that involved FaultDate, and achieves the same goal.

Here it is, rewritten to use a subquery to avoid the variable declaration and subsequent SELECT.

SELECT 
  COUNT(FF.HALID)
FROM
  Outages.FaultsInOutages AS OFIO 
  INNER JOIN Faults.Faults as FF ON 
    FF.HALID = OFIO.HALID 
WHERE
  CONVERT(varchar(10), FF.FaultDate, 126) = (SELECT CONVERT(varchar(10), OO.Date, 126) FROM OLAP.OutageHours AS OO where OO.OutageID = 1) AND
  OFIO.OutageID = 1

Note that this approach has the same index usage issue as the original, because of the use of CONVERT() on FF.FaultDate. This could be remedied by adding the subquery twice, but you would be better served with the variable approach in this case. This last version is only for demonstration.

Beware of localization issues: what is a swearword in one language might be a perfectly normal word in another.

One current example of this: ebay uses a dictionary approach to filter "bad words" from feedback. If you try to enter the german translation of "this was a perfect transaction" ("das war eine perfekte Transaktion"), ebay will reject the feedback due to bad words.

Why? Because the german word for "was" is "war", and "war" is in ebay dictionary of "bad words".

So beware of localisation issues.

Check Demo: https://stackblitz.com/edit/angular-6-checkbox?embed=1&file=src/app/app.component.html

  CheckBox: use change event to call the function and pass the event.

<label class="container">    
   <input type="checkbox" [(ngModel)]="theCheckbox"  data-md-icheck 
    (change)="toggleVisibility($event)"/>
      Checkbox is <span *ngIf="marked">checked</span><span 
     *ngIf="!marked">unchecked</span>
     <span class="checkmark"></span>
</label>
 <div>And <b>ngModel</b> also works, it's value is <b>{{theCheckbox}}</b></div>

Output the images in a lossless format such as PNG:

ffmpeg.exe -i 10fps.h264 -r 10 -f image2 10fps.h264_%03d.png

Edit/Update: Not quite sure why I originally gave a strange filename example (with a possibly made-up extension).

I have since found that -vsync 0 is simpler than -r 10 because it avoids needing to know the frame rate.

This is something like what I currently use:

mkdir stills
ffmpeg -i my-film.mp4 -vsync 0 -f image2 stills/my-film-%06d.png

To extract only the key frames (which are likely to be of higher quality post-edit):

ffmpeg -skip_frame nokey -i my-film.mp4 -vsync 0 -f image2 stills/my-film-%06d.png

Then use another program (where you can more precisely specify quality, subsampling and DCT method – e.g. GIMP) to convert the PNGs you want to JPEG.

It is possible to obtain slightly sharper images in JPEG format this way than is possible with -qmin 1 -q:v 1 and outputting as JPEG directly from ffmpeg.

this is one:

ls -l . | egrep -c '^-'

Note:

ls -1 | wc -l

Which means: ls: list files in dir

-1: (that's a ONE) only one entry per line. Change it to -1a if you want hidden files too

|: pipe output onto...

wc: "wordcount"

-l: count lines.

you can raise the click event on an element by doing

// this must be done after input1 exists in the DOM
var element = document.getElementById("input1");

if (element) element.click();

Example here

In C, there's no (real, distinct type of) strings. Every C "string" is an array of chars, zero terminated.

Therefore, to extract a character c at index i from string your_string, just use

char c = your_string[i];

Index is base 0 (first character is your_string[0], second is your_string[1]...).

Unfortunately that approach is not portable C++ (so far).

All standard names are in namespace std and moreover you cannot know which names are NOT defined by including and header (in other words it's perfectly legal for an implementation to declare the name std::string directly or indirectly when using #include <vector>).

Despite this however you are required by the language to know and tell the compiler which standard header includes which part of the standard library. This is a source of portability bugs because if you forget for example #include <map> but use std::map it's possible that the program compiles anyway silently and without warnings on a specific version of a specific compiler, and you may get errors only later when porting to another compiler or version.

In my opinion there are no valid technical excuses because this is necessary for the general user: the compiler binary could have all standard namespace built in and this could actually increase the performance even more than precompiled headers (e.g. using perfect hashing for lookups, removing standard headers parsing or loading/demarshalling and so on).

The use of standard headers simplifies the life of who builds compilers or standard libraries and that's all. It's not something to help users.

However this is the way the language is defined and you need to know which header defines which names so plan for some extra neurons to be burnt in pointless configurations to remember that (or try to find and IDE that automatically adds the standard headers you use and removes the ones you don't... a reasonable alternative).

You could also use a dummy form arround it like:

<mat-card-footer>
<form (submit)="search(ref, id, forename, surname, postcode)" action="#">
  <button mat-raised-button type="submit" class="successButton" id="invSearch" title="Click to perform search." >Search</button>
</form>
</mat-card-footer>

the search function has to return false to make sure that the action doesn't get executed.
Just make sure the form is focused (should be when you have the input in the form) when you press enter.

I had the same problem with a Google Docs URL. Enclosing the URL in quotes did the trick for me:

wget "https://docs.google.com/spreadsheets/export?format=tsv&id=1sSi9f6m-zKteoXA4r4Yq-zfdmL4rjlZRt38mejpdhC23" -O sheet.tsv

From your description, what you probably want is os.Readdirnames.

func (f *File) Readdirnames(n int) (names []string, err error)

Readdirnames reads the contents of the directory associated with file and returns a slice of up to n names of files in the directory, in directory order. Subsequent calls on the same file will yield further names.

...

If n <= 0, Readdirnames returns all the names from the directory in a single slice.

Snippet:

file, err := os.Open(path)
if err != nil {
    return err
}
defer file.Close()
names, err := file.Readdirnames(0)
if err != nil {
    return err
}
fmt.Println(names)

You can directly add a constraint for table

ALTER TABLE TableName
ADD CONSTRAINT ConstraintName PRIMARY KEY(ColumnName)
GO 

Make sure your primary key column should not have any null values.

Option 2:

you can change your SQL Management Studio Options like

To change this option, on the Tools menu, click Options, expand Designers, and then click Table and Database Designers. Select or clear the Prevent saving changes that require the table to be re-created check box.

>>> arr = numpy.array(((2,2),(2,-2)))
>>> tuple(map(tuple, arr))
((2, 2), (2, -2))

To make sure the event always only fires once, you can use Jquery .one() . JQuery one ensures that your event handler only called once. Additionally, you can subscribe your event handler with one to allow further clicks when you have finished the processing of the current click operation.

<div id="testDiv">
  <button class="testClass">Test Button</button>
</div>

…

var subscribeClickEvent = function() {$("#testDiv").one("click", ".testClass", clickHandler);};

function clickHandler() {
  //... perform the tasks  
  alert("you clicked the button");
  //... subscribe the click handler again when the processing of current click operation is complete  
  subscribeClickEvent();
}

subscribeClickEvent();

var students = ["Kofi", "Abena", "Peter", "Kweku", "Akosua"]

students.sort(by: >)

print(students)

Prints : "["Peter", "Kweku", "Kofi", "Akosua", "Abena"]"

You can use this keyword to access custom data, passed to $.ajax() function:

    $.ajax({
        // ... // --> put ajax configuration parameters here
        yourCustomData: {param1: 'any value', time: '1h24'},  // put your custom key/value pair here
        success: successHandler
    });

    function successHandler(data, textStatus, jqXHR) {
        alert(this.yourCustomData.param1);  // shows "any value"
        console.log(this.yourCustomData.time);
    }

For what it's worth, I've had a similar issue - when trying to add a specific allowed origin (not *).

Turns out i had to correct

<AllowedOrigin>http://mydomain:3000/</AllowedOrigin>

to

The most simple way is to use Record type Record<number, productDetails >

interface productDetails {
   productId : number , 
   price : number , 
   discount : number
};

const myVar : Record<number, productDetails> = {
   1: {
       productId : number , 
       price : number , 
       discount : number
   }
}

Since you're dealing with static content...

On the folder that acts as the root of your website- if you right click > properties > security, does "Users" show up in the list? if not click "Add..." and type it in, be sure to click "Apply" when you're done.

In my case, the problem was caused by the hosting provider I was using blocking http packets addressed to their IP block that originated from within their IP block. Un-frickin-believable!!!

Well, I understand this question is Visual Studio GUI related, but maybe the asker can try this trick also. Just giving a different perspective in solving this problem.

I like to use terminal a lot for GIT, so here are the simple steps:

Pre-requisites...

• If it's Linux or MAC, you should have git packages installed on your machine
• If it's Windows, you can try to download git bash software

Now,

1. Goto Github.com
2. In your account, create a New Repository

3. Don't create any file inside the repository. Keep it empty. Copy its URL. It should be something like https://github.com/Username/ProjectName.git

4. Open up the terminal and redirect to your Visual Studio Project directory

5. Configure your credentials

   git config --global user.name "your_git_username"
   git config --global user.email "your_git_email"
   

6. Then type these commands

   git init
   git add .
   git commit -m "First Migration Commit"
   git remote add origin paste_your_URL_here
   git push -u origin master
   

Done...Hope this helps

Neither way is necessarily correct or incorrect, they are just two different kinds of class elements:

• Elements outside the __init__ method are static elements; they belong to the class.
• Elements inside the __init__ method are elements of the object (self); they don't belong to the class.

You'll see it more clearly with some code:

class MyClass:
    static_elem = 123

    def __init__(self):
        self.object_elem = 456

c1 = MyClass()
c2 = MyClass()

# Initial values of both elements
>>> print c1.static_elem, c1.object_elem 
123 456
>>> print c2.static_elem, c2.object_elem
123 456

# Nothing new so far ...

# Let's try changing the static element
MyClass.static_elem = 999

>>> print c1.static_elem, c1.object_elem
999 456
>>> print c2.static_elem, c2.object_elem
999 456

# Now, let's try changing the object element
c1.object_elem = 888

>>> print c1.static_elem, c1.object_elem
999 888
>>> print c2.static_elem, c2.object_elem
999 456

As you can see, when we changed the class element, it changed for both objects. But, when we changed the object element, the other object remained unchanged.

    This implements a custom SQL lookup when using `__date` with datetimes.
    To enable filtering on datetimes that fall on a given date, import

    """
    lookup_name = 'date'

    def as_sql(self, compiler, connection):
        lhs, params = compiler.compile(self.lhs)
        return 'DATE({})'.format(lhs), params

    @property
    def output_field(self):
        return models.DateField()

Then you can use it in your filters like this:

Foo.objects.filter(created_on__date=date)

EDIT

This solution is definitely back end dependent. From the article:

Of course, this implementation relies on your particular flavor of SQL having a DATE() function. MySQL does. So does SQLite. On the other hand, I haven’t worked with PostgreSQL personally, but some googling leads me to believe that it does not have a DATE() function. So an implementation this simple seems like it will necessarily be somewhat backend-dependent.

Use charAt:

The charAt() method returns the character at the specified index in a string.

You can use this method in conjunction with the length property of a string to get the last character in that string.
For example:

const myString = "linto.yahoo.com.";_x000D_
const stringLength = myString.length; // this will be 16_x000D_
console.log('lastChar: ', myString.charAt(stringLength - 1)); // this will be the string

Much easier – this is what I use to avoid Shortlink tracking – is the following:

curl -IL http://bit.ly/in-the-shadows

…which also follows links.

Keeping your commands short will make them easier to remember:

git log --graph --oneline

You need to put the font files in assets folder (may be a fonts sub-folder within assets) and refer to it in the styles:

@font-face {
  font-family: lato;
  src: url(assets/font/Lato.otf) format("opentype");
}

Once done, you can apply this font any where like:

* {
  box-sizing: border-box;
  margin: 0;
  padding: 0;
  font-family: 'lato', 'arial', sans-serif;
}

You can put the @font-face definition in your global styles.css or styles.scss and you would be able to refer to the font anywhere - even in your component specific CSS/SCSS. styles.css or styles.scss is already defined in angular-cli.json. Or, if you want you can create a separate CSS/SCSS file and declare it in angular-cli.json along with the styles.css or styles.scss like:

"styles": [
  "styles.css",
  "fonts.css"
],

The error is because you are including the script links at two places which will do the override and re-initialization of date-picker

<meta charset="utf-8">_x000D_
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" />_x000D_

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>

So exclude either src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"

or src="http://code.jquery.com/ui/1.11.0/jquery-ui.js"

It will work..

you can use the views *_DEPENDENCIES, for example:

SELECT owner, NAME
  FROM dba_dependencies
 WHERE referenced_owner = :table_owner
   AND referenced_name = :table_name
   AND TYPE IN ('PACKAGE', 'PACKAGE BODY')

Your question title and your question body are different. Ruby does not have a starts_with? method. Rails, which is a Ruby framework, however, does, as sepp2k states. See his comment on his answer for the link to the documentation for it.

You could always use a regular expression though:

if SomeString.match(/^abc/) 
   # SomeString starts with abc

^ means "start of string" in regular expressions

I have used this and it works for me.Also include jquery migrate plugin,and jquery file.

if ( $.browser.webkit ) {
alert( "This is WebKit!" );
}

To answer people thinking you "have to" use vector instead of unique_ptr I have a case in CUDA programming on GPU when you allocate memory in Device you must go for a pointer array (with cudaMalloc). Then, when retrieving this data in Host, you must go again for a pointer and unique_ptr is fine to handle pointer easily. The extra cost of converting double* to vector<double> is unnecessary and leads to a loss of perf.

You might have gone through theory part from the above posts:

-The clustered Index as we can see points directly to record i.e. its direct so it takes less time for a search. Additionally it will not take any extra memory/space to store the index

-While, in non-clustered Index, it indirectly points to the clustered Index then it will access the actual record, due to its indirect nature it will take some what more time to access.Also it needs its own memory/space to store the index

I had the same problem when adding react-native-palette to my project, here is my dependencies tree:

./gradlew app:dependencies
+--- project :react-native-palette
|    +--- com.facebook.react:react-native:0.20.+ -> 0.44.2
|    |    +--- javax.inject:javax.inject:1
|    |    +--- com.android.support:appcompat-v7:23.0.1
|    |    |    \--- com.android.support:support-v4:23.0.1
|    |    |         \--- com.android.support:support-annotations:23.0.1 -> 24.2.1
...
|    \--- com.android.support:palette-v7:24.+ -> 24.2.1
|         +--- com.android.support:support-compat:24.2.1
|         |    \--- com.android.support:support-annotations:24.2.1
|         \--- com.android.support:support-core-utils:24.2.1
|              \--- com.android.support:support-compat:24.2.1 (*)
+--- com.android.support:appcompat-v7:23.0.1 (*)
\--- com.facebook.react:react-native:+ -> 0.44.2 (*)

I tried many solutons and could not fix it, until changing the com.android.support:appcompat version in android/app/build.gradle, I wish this can help:

dependencies {
    compile project(':react-native-palette')
    compile project(':react-native-image-picker')
    compile project(':react-native-camera')
    compile fileTree(dir: "libs", include: ["*.jar"])
    // compile "com.android.support:appcompat-v7:23.0.1"
    compile "com.android.support:appcompat-v7:24.2.1"
    compile "com.facebook.react:react-native:+"
}

it seems that multiple entries is not a big problem, version mismatch is

Sample

var yourString = "first line \n second line \n third line"

In case, you don't find the + operator suitable
