Try like this.

You must give a function as value to onClick()

You button:

<button type="button" onClick={ refreshPage }> <span>Reload</span> </button> 

refreshPage function:

function refreshPage(){ 
    window.location.reload(); 
}

It is the entity used to represent a non-breaking space. It is essentially a standard space, the primary difference being that a browser should not break (or wrap) a line of text at the point that this   occupies.

var a = 'something' + '&nbsp &nbsp &nbsp &nbsp &nbsp' + 'something'

Non-breaking Space

A common character entity used in HTML is the non-breaking space ( ).

Remember that browsers will always truncate spaces in HTML pages. If you write 10 spaces in your text, the browser will remove 9 of them. To add real spaces to your text, you can use the   character entity.

Demo

var a = 'something' + '&nbsp &nbsp &nbsp &nbsp &nbsp' + 'something';_x000D_
_x000D_
document.body.innerHTML = a;

Conceptually there are the two "domains" classes and interfaces. Inside these domains you are always extending, only a class implements an interface, which is kind of "crossing the border". So basically "extends" for interfaces mirrors the behavior for classes. At least I think this is the logic behind. It seems than not everybody agrees with this kind of logic (I find it a little bit contrived myself), and in fact there is no technical reason to have two different keywords at all.

This is a symlink resolver in Bash that works whether the link is a directory or a non-directory:

function readlinks {(
  set -o errexit -o nounset
  declare n=0 limit=1024 link="$1"

  # If it's a directory, just skip all this.
  if cd "$link" 2>/dev/null
  then
    pwd -P
    return 0
  fi

  # Resolve until we are out of links (or recurse too deep).
  while [[ -L $link ]] && [[ $n -lt $limit ]]
  do
    cd "$(dirname -- "$link")"
    n=$((n + 1))
    link="$(readlink -- "${link##*/}")"
  done
  cd "$(dirname -- "$link")"

  if [[ $n -ge $limit ]]
  then
    echo "Recursion limit ($limit) exceeded." >&2
    return 2
  fi

  printf '%s/%s\n' "$(pwd -P)" "${link##*/}"
)}

Note that all the cd and set stuff takes place in a subshell.

As Marc says, you run it exactly like you would from the command line. See Creating SQL Server Agent Jobs on MSDN.

I set the column widths in the HTML markup like so:

    <thead>
        <tr>

            <th style='width: 5%;'>ProjectId</th>
            <th style='width: 15%;'>Title</th>
            <th style='width: 40%;'>Abstract</th>
            <th style='width: 20%;'>Keywords</th>
            <th style='width: 10%;'>PaperName</th>
            <th style='width: 10%;'>PaperURL</th>
        </tr>
    </thead>
    <tbody>
        @foreach (var item in Model)
        {
            <tr id="@item.ID">
                <td>@item.ProjectId</td>
                <td>@item.Title</td>
                <td>@item.Abstract</td>
                <td>@item.Keywords</td>
                <td>@item.PaperName</td>
                <td>@item.PaperURL</td>
            </tr>
        }
    </tbody>
</table>

Your tables should have as immediate children just tbody and thead elements, with the rows within*. So, amend the HTML to be:

<table border="1" width="100%" id="test">
  <tbody>
    <tr>
     <td>
      <table border="1" width="100%">
        <tbody>
          <tr>
            <td>table 2</td>
          </tr>
        </tbody>
      </table>
     </td>
    </tr> 
    <tr><td>table 1</td></tr>
    <tr><td>table 1</td></tr>
    <tr><td>table 1</td></tr>
  </tbody>
</table>

Then amend your selector slightly to this:

#test > tbody > tr:last-child { background:#ff0000; }

See it in action here. That makes use of the child selector, which:

...separates two selectors and matches only those elements matched by the second selector that are direct children of elements matched by the first.

So, you are targeting only direct children of tbody elements that are themselves direct children of your #test table.

Alternative solution

The above is the neatest solution, as you don't need to over-ride any styles. The alternative would be to stick with your current set-up, and over-ride the background style for the inner table, like this:

#test tr:last-child { background:#ff0000; }
#test table tr:last-child { background:transparent; }

* It's not mandatory but most (all?) browsers will add these in, so it's best to make it explicit. As @BoltClock states in the comments:

...it's now set in stone in HTML5, so for a browser to be compliant it basically must behave this way.

dataGridView1.EnableHeadersVisualStyles = false;
dataGridView1.ColumnHeadersDefaultCellStyle.BackColor = Color.Blue;

@eric answer did the trick for me, you need to accept terms in the command you are setting i.e

"Cookie: oraclelicense=accept-securebackup-cookie"

so your final command looks thus

wget -c --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-linux-x64.tar.gz

You can decide to update the version by changing 8u131 to 8uXXX. so long it is available in the repo.

I had the same issue when I was using GIT bash to merge master branch in to my feature branch. I followed the following steps to overcome this.

1. press 'i' (To insert a merge message)
2. write your merge message
3. press esc button (To go back)
4. write ':wq' (write & quit)
5. then press enter

Just use String.IndexOf twice as in:

     string str = "My Test String";
     int index = str.IndexOf(' ');
     index = str.IndexOf(' ', index + 1);
     string result = str.Substring(0, index);

try this

 lblMsg.Text = @"Your search result for <b style=""color:green;"">" + txtCode.Text.Trim() + "</b> ";

The drawPolygon function below can be used to draw any polygon with rounded corners.

See it running here.

function drawPolygon(ctx, pts, radius) {
  if (radius > 0) {
    pts = getRoundedPoints(pts, radius);
  }
  var i, pt, len = pts.length;
  ctx.beginPath();
  for (i = 0; i < len; i++) {
    pt = pts[i];
    if (i == 0) {          
      ctx.moveTo(pt[0], pt[1]);
    } else {
      ctx.lineTo(pt[0], pt[1]);
    }
    if (radius > 0) {
      ctx.quadraticCurveTo(pt[2], pt[3], pt[4], pt[5]);
    }
  }
  ctx.closePath();
}

function getRoundedPoints(pts, radius) {
  var i1, i2, i3, p1, p2, p3, prevPt, nextPt,
      len = pts.length,
      res = new Array(len);
  for (i2 = 0; i2 < len; i2++) {
    i1 = i2-1;
    i3 = i2+1;
    if (i1 < 0) {
      i1 = len - 1;
    }
    if (i3 == len) {
      i3 = 0;
    }
    p1 = pts[i1];
    p2 = pts[i2];
    p3 = pts[i3];
    prevPt = getRoundedPoint(p1[0], p1[1], p2[0], p2[1], radius, false);
    nextPt = getRoundedPoint(p2[0], p2[1], p3[0], p3[1], radius, true);
    res[i2] = [prevPt[0], prevPt[1], p2[0], p2[1], nextPt[0], nextPt[1]];
  }
  return res;
};

function getRoundedPoint(x1, y1, x2, y2, radius, first) {
  var total = Math.sqrt(Math.pow(x2 - x1, 2) + Math.pow(y2 - y1, 2)),
      idx = first ? radius / total : (total - radius) / total;
  return [x1 + (idx * (x2 - x1)), y1 + (idx * (y2 - y1))];
};

The function receives an array with the polygon points, like this:

var canvas = document.getElementById("cv");
var ctx = canvas.getContext("2d");
ctx.strokeStyle = "#000000";
ctx.lineWidth = 5;

drawPolygon(ctx, [[20,   20],
                  [120,  20],
                  [120, 120],
                  [ 20, 120]], 10);
ctx.stroke();

This is a port and a more generic version of a solution posted here.

There's a method for this in Roslyn's Microsoft.CodeAnalysis.CSharp package on nuget :

    private static string ToLiteral(string valueTextForCompiler)
    {
        return Microsoft.CodeAnalysis.CSharp.SymbolDisplay.FormatLiteral(valueTextForCompiler, false);
    }

Obviously this didn't exist at the time of the original question, but might help people who end up here from Google.

Creating new types in a fully dynamic manner

>>> NewType = type("NewType", (object,), {"x": "hello"})
>>> n = NewType()
>>> n.x
"hello"

which is exactly the same as

>>> class NewType(object):
>>>     x = "hello"
>>> n = NewType()
>>> n.x
"hello"

Probably not the most useful thing, but nice to know.

Edit: Fixed name of new type, should be NewType to be the exact same thing as with class statement.

Edit: Adjusted the title to more accurately describe the feature.

height:59.55%;//First specify your height then make overflow auto overflow:auto;

I think you can try this.

MyObject myObj = GetMyObj(); // Create and fill a new object
MyObject newObj = new MyObject(myObj); //DeepClone it

It's Very simple there are only TWO step just copy and paste :

step 1.

  SET @DATABASE_NAME = 'name_of_your_db';
  SELECT  CONCAT('ALTER TABLE `', table_name, '` ENGINE=InnoDB;') AS  sql_statements FROM information_schema.tables AS tb WHERE   table_schema = @DATABASE_NAME AND `ENGINE` = 'MyISAM' AND `TABLE_TYPE` = 'BASE TABLE' ORDER BY table_name DESC;

(copy and paste all result in in sql tab)

step 2: (copy all result in in sql tab) and paste below in the line

START TRANSACTION;

COMMIT;

eg. START TRANSACTION;

ALTER TABLE admin_files ENGINE=InnoDB;

COMMIT;

Random color generation with brightness control:

function getRandColor(brightness){

    // Six levels of brightness from 0 to 5, 0 being the darkest
    var rgb = [Math.random() * 256, Math.random() * 256, Math.random() * 256];
    var mix = [brightness*51, brightness*51, brightness*51]; //51 => 255/5
    var mixedrgb = [rgb[0] + mix[0], rgb[1] + mix[1], rgb[2] + mix[2]].map(function(x){ return Math.round(x/2.0)})
    return "rgb(" + mixedrgb.join(",") + ")";
}

You can have almost any character, including most Unicode characters! The exact definition is in the Java Language Specification under section 3.8: Identifiers.

An identifier is an unlimited-length sequence of Java letters and Java digits, the first of which must be a Java letter. ...

Letters and digits may be drawn from the entire Unicode character set, ... This allows programmers to use identifiers in their programs that are written in their native languages.

An identifier cannot have the same spelling (Unicode character sequence) as a keyword (§3.9), boolean literal (§3.10.3), or the null literal (§3.10.7), or a compile-time error occurs.

However, see this question for whether or not you should do that.

Notice: I do update this answer as I find better solutions. I also keep the old answers for future reference as long as they remain related. Latest and best answer comes first.

Better answer:

Directives in angularjs are very powerful, but it takes time to comprehend which processes lie behind them.

While creating directives, angularjs allows you to create an isolated scope with some bindings to the parent scope. These bindings are specified by the attribute you attach the element in DOM and how you define scope property in the directive definition object.

There are 3 types of binding options which you can define in scope and you write those as prefixes related attribute.

angular.module("myApp", []).directive("myDirective", function () {
    return {
        restrict: "A",
        scope: {
            text: "@myText",
            twoWayBind: "=myTwoWayBind",
            oneWayBind: "&myOneWayBind"
        }
    };
}).controller("myController", function ($scope) {
    $scope.foo = {name: "Umur"};
    $scope.bar = "qwe";
});

HTML

<div ng-controller="myController">
    <div my-directive my-text="hello {{ bar }}" my-two-way-bind="foo" my-one-way-bind="bar">
    </div>
</div>

In that case, in the scope of directive (whether it's in linking function or controller), we can access these properties like this:

/* Directive scope */

in: $scope.text
out: "hello qwe"
// this would automatically update the changes of value in digest
// this is always string as dom attributes values are always strings

in: $scope.twoWayBind
out: {name:"Umur"}
// this would automatically update the changes of value in digest
// changes in this will be reflected in parent scope

// in directive's scope
in: $scope.twoWayBind.name = "John"

//in parent scope
in: $scope.foo.name
out: "John"


in: $scope.oneWayBind() // notice the function call, this binding is read only
out: "qwe"
// any changes here will not reflect in parent, as this only a getter .

"Still OK" Answer:

Since this answer got accepted, but has some issues, I'm going to update it to a better one. Apparently, $parse is a service which does not lie in properties of the current scope, which means it only takes angular expressions and cannot reach scope. {{,}} expressions are compiled while angularjs initiating which means when we try to access them in our directives postlink method, they are already compiled. ({{1+1}} is 2 in directive already).

This is how you would want to use:

var myApp = angular.module('myApp',[]);

myApp.directive('myDirective', function ($parse) {
    return function (scope, element, attr) {
        element.val("value=" + $parse(attr.myDirective)(scope));
    };
});

function MyCtrl($scope) {
    $scope.aaa = 3432;
}?

.

<div ng-controller="MyCtrl">
    <input my-directive="123">
    <input my-directive="1+1">
    <input my-directive="'1+1'">
    <input my-directive="aaa">
</div>????????

One thing you should notice here is that, if you want set the value string, you should wrap it in quotes. (See 3rd input)

Here is the fiddle to play with: http://jsfiddle.net/neuTA/6/

Old Answer:

I'm not removing this for folks who can be misled like me, note that using $eval is perfectly fine the correct way to do it, but $parse has a different behavior, you probably won't need this to use in most of the cases.

The way to do it is, once again, using scope.$eval. Not only it compiles the angular expression, it has also access to the current scope's properties.

var myApp = angular.module('myApp',[]);

myApp.directive('myDirective', function () {
    return function (scope, element, attr) {
        element.val("value = "+ scope.$eval(attr.value));
    }
});

function MyCtrl($scope) {
   
}?

What you are missing was $eval.

http://docs.angularjs.org/api/ng.$rootScope.Scope#$eval

Executes the expression on the current scope returning the result. Any exceptions in the expression are propagated (uncaught). This is useful when evaluating angular expressions.

The problem here is that your timer starts a thread and when it runs the callback function, the callback function ( updatelistview) is accessing controls on UI thread so this can not be done becuase of this

I think you need the Web Tools Platform package for this. Not very sure though. You can add it to your current eclipse through Help > install new software.

Then add the software repository site location for WTP for your version of eclipse. This is how you can install plugins in eclipse.

One of the most important thing to remember when decorating a method with async is that at least there is one await operator inside the method. In your example, I would translate it as shown below using TaskCompletionSource.

private Task<int> DoWorkAsync()
{
    //create a task completion source
    //the type of the result value must be the same
    //as the type in the returning Task
    TaskCompletionSource<int> tcs = new TaskCompletionSource<int>();
    Task.Run(() =>
    {
        int result = 1 + 2;
        //set the result to TaskCompletionSource
        tcs.SetResult(result);
    });
    //return the Task
    return tcs.Task;
}

private async void DoWork()
{
    int result = await DoWorkAsync();
}

Since nobody did cover this question of the OP yet:

What I wanted to do:

Make a python module install-able with "pip install ..."

Here is an absolute minimal example, showing the basic steps of preparing and uploading your package to PyPI using setuptools and twine.

This is by no means a substitute for reading at least the tutorial, there is much more to it than covered in this very basic example.

Creating the package itself is already covered by other answers here, so let us assume we have that step covered and our project structure like this:

.
+-- hellostackoverflow/
    +-- __init__.py
    +-- hellostackoverflow.py

In order to use setuptools for packaging, we need to add a file setup.py, this goes into the root folder of our project:

.
+-- setup.py
+-- hellostackoverflow/
    +-- __init__.py
    +-- hellostackoverflow.py

At the minimum, we specify the metadata for our package, our setup.py would look like this:

from setuptools import setup

setup(
    name='hellostackoverflow',
    version='0.0.1',
    description='a pip-installable package example',
    license='MIT',
    packages=['hellostackoverflow'],
    author='Benjamin Gerfelder',
    author_email='[email protected]',
    keywords=['example'],
    url='https://github.com/bgse/hellostackoverflow'
)

Since we have set license='MIT', we include a copy in our project as LICENCE.txt, alongside a readme file in reStructuredText as README.rst:

.
+-- LICENCE.txt
+-- README.rst
+-- setup.py
+-- hellostackoverflow/
    +-- __init__.py
    +-- hellostackoverflow.py

At this point, we are ready to go to start packaging using setuptools, if we do not have it already installed, we can install it with pip:

pip install setuptools

In order to do that and create a source distribution, at our project root folder we call our setup.py from the command line, specifying we want sdist:

python setup.py sdist

This will create our distribution package and egg-info, and result in a folder structure like this, with our package in dist:

.
+-- dist/
+-- hellostackoverflow.egg-info/
+-- LICENCE.txt
+-- README.rst
+-- setup.py
+-- hellostackoverflow/
    +-- __init__.py
    +-- hellostackoverflow.py

At this point, we have a package we can install using pip, so from our project root (assuming you have all the naming like in this example):

pip install ./dist/hellostackoverflow-0.0.1.tar.gz

If all goes well, we can now open a Python interpreter, I would say somewhere outside our project directory to avoid any confusion, and try to use our shiny new package:

Python 3.5.2 (default, Sep 14 2017, 22:51:06) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from hellostackoverflow import hellostackoverflow
>>> hellostackoverflow.greeting()
'Hello Stack Overflow!'

Now that we have confirmed the package installs and works, we can upload it to PyPI.

Since we do not want to pollute the live repository with our experiments, we create an account for the testing repository, and install twine for the upload process:

pip install twine

Now we're almost there, with our account created we simply tell twine to upload our package, it will ask for our credentials and upload our package to the specified repository:

twine upload --repository-url https://test.pypi.org/legacy/ dist/*

We can now log into our account on the PyPI test repository and marvel at our freshly uploaded package for a while, and then grab it using pip:

pip install --index-url https://test.pypi.org/simple/ hellostackoverflow

As we can see, the basic process is not very complicated. As I said earlier, there is a lot more to it than covered here, so go ahead and read the tutorial for more in-depth explanation.

1. in eclipse go run - > run configuration

2. in there go to JRE tab in right side panels

3. in VM Arguments section paste this

   -Duser.timezone=GMT

4. then Apply - > Run

More flexible way is to use FileTimeFilterJS.bat:

@echo off

::::::::::::::::::::::
set "_DIR=C:\Users\npocmaka\Downloads"
set "_DAYS=-5"
::::::::::::::::::::::

for /f "tokens=* delims=" %%# in ('FileTimeFilterJS.bat  "%_DIR%" -dd %_DAYS%') do (
    echo deleting  "%%~f#"
    echo del /q /f "%%~f#"
)

The script will allow you to use measurements like days, minutes ,seconds or hours. To choose weather to filter the files by time of creation, access or modification To list files before or after a certain date (or between two dates) To choose if to show files or dirs (or both) To be recursive or not

better to use touchstart event with .on() jQuery method:

$(window).load(function() { // better to use $(document).ready(function(){
    $('.List li').on('click touchstart', function() {
        $('.Div').slideDown('500');
    });
});

And i don't understand why you are using $(window).load() method because it waits for everything on a page to be loaded, this tend to be slow, while you can use $(document).ready() method which does not wait for each element on the page to be loaded first.

For completeness, guava also has a handy utility for this

ByteStreams.copy(input, output);

Set the PGPASSWORD environment variable inside the script before calling psql

PGPASSWORD=pass1234 psql -U MyUsername myDatabaseName

For reference, see http://www.postgresql.org/docs/current/static/libpq-envars.html

Edit

Since Postgres 9.2 there is also the option to specify a connection string or URI that can contain the username and password.

Using that is a security risk because the password is visible in plain text when looking at the command line of a running process e.g. using ps (Linux), ProcessExplorer (Windows) or similar tools, by other users.

One nice feature of the Immediate Window in Visual Studio is its ability to evaluate the return value of a method particularly if it is called by your client code but it is not part of a variable assignment. In Debug mode, as mentioned, you can interact with variables and execute expressions in memory which plays an important role in being able to do this.

For example, if you had a static method that returns the sum of two numbers such as:

private static int GetSum(int a, int b)
{
    return a + b;
}

Then in the Immediate Window you can type the following:

? GetSum(2, 4)
6

As you can seen, this works really well for static methods. However, if the method is non-static then you need to interact with a reference to the object the method belongs to.

For example, let’s say this is what your class looks like:

private class Foo
{
    public string GetMessage()
    {
        return "hello";
    }
}

If the object already exists in memory and it’s in scope, then you can call it in the Immediate Window as long as it has been instantiated before your current breakpoint (or, at least, before wherever the code is paused in debug mode):

? foo.GetMessage(); // object ‘foo’ already exists
"hello"

In addition, if you want to interact and test the method directly without relying on an existing instance in memory, then you can instantiate your own instance in the Immediate Window:

? Foo foo = new Foo(); // new instance of ‘Foo’
{temp.Program.Foo}
? foo.GetMessage()
"hello"

You can take it a step further and temporarily assign the method's results to variables if you want to do further evaluations, calculations, etc.:

? string msg = foo.GetMessage();
"hello"
? msg + " there!"
"hello there!"

Furthermore, if you don’t even want to declare a variable name for a new object and just want to run one of its methods/functions then do this:

? new Foo().GetMessage()
"hello" 

A very common way to see the value of a method is to select the method name of a class and do a ‘Add Watch’ so that you can see its current value in the Watch window. However, once again, the object needs to be instantiated and in scope for a valid value to be displayed. This is much less powerful and more restrictive than using the Immediate Window.

Along with inspecting methods, you can do simple math equations:

? 5 * 6
30

or compare values:

? 5==6
false
? 6==6
true

The question mark ('?') is unnecessary if you are in directly in the Immediate Window but it is included here for clarity (to distinguish between the typed in expressions versus the results.) However, if you are in the Command Window and need to do some quick stuff in the Immediate Window then precede your statements with '?' and off you go.

Intellisense works in the Immediate Window, but it sometimes can be a bit inconsistent. In my experience, it seems to be only available in Debug mode, but not in design, non-debug mode.

Unfortunately, another drawback of the Immediate Window is that it does not support loops.

Your code can get messy fast when dealing with CSS3 transitions. I would recommend using a plugin such as jQuery Transit that handles the complexity of CSS3 animations/transitions.

Moreover, the plugin uses webkit-transform rather than webkit-transition, which allows for mobile devices to use hardware acceleration in order to give your web apps that native look and feel when the animations occur.

JS Fiddle Live Demo

Javascript:

$("#startTransition").on("click", function()
{

    if( $(".boxOne").is(":visible")) 
    {
        $(".boxOne").transition({ x: '-100%', opacity: 0.1 }, function () { $(".boxOne").hide(); });
        $(".boxTwo").css({ x: '100%' });
        $(".boxTwo").show().transition({ x: '0%', opacity: 1.0 });
        return;        
    }

    $(".boxTwo").transition({ x: '-100%', opacity: 0.1 }, function () { $(".boxTwo").hide(); });
    $(".boxOne").css({ x: '100%' });
    $(".boxOne").show().transition({ x: '0%', opacity: 1.0 });

});

Most of the hard work of getting cross-browser compatibility is done for you as well and it works like a charm on mobile devices.

Hive has a relational database on the master node it uses to keep track of state. For instance, when you CREATE TABLE FOO(foo string) LOCATION 'hdfs://tmp/';, this table schema is stored in the database.

If you have a partitioned table, the partitions are stored in the database(this allows hive to use lists of partitions without going to the file-system and finding them, etc). These sorts of things are the 'metadata'.

When you drop an internal table, it drops the data, and it also drops the metadata.

When you drop an external table, it only drops the meta data. That means hive is ignorant of that data now. It does not touch the data itself.

Adding value to all these answers,

many have asked the command for running App in AVD after build sucessful.

adb install -r {path-to-your-bild-folder}/{yourAppName}.apk

I have developed a light weighted library for android, you can visit https://github.com/ChathuraHettiarachchi/RecycleClick

and follow for following sample

RecycleClick.addTo(YOUR_RECYCLEVIEW).setOnItemClickListener(new RecycleClick.OnItemClickListener() {
            @Override
            public void onItemClicked(RecyclerView recyclerView, int position, View v) {
                // YOUR CODE
            }
        });

Update to @CodeNotFound's answer.

In EF Core 3.0 DbQuery<T> has been deprecated, instead you should use Keyless entity types which supposedly does the same thing. These are configured with the ModelBuilder HasNoKey() method. In your DbContext class, do this

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder
        .Entity<YourEntityType>(eb =>
        {
            eb.HasNoKey();
        });

}

There are restrictions though, notably:

• Are never tracked for changes in the DbContext and therefore are never inserted, updated or deleted on the database.
• Only support a subset of navigation mapping capabilities, specifically:
  • They may never act as the principal end of a relationship.
  • They may not have navigations to owned entities
  • They can only contain reference navigation properties pointing to regular entities.
  • Entities cannot contain navigation properties to keyless entity types.

This means that for the question of

If I want to use them and modify data, must I necessarily add a PK to those tables, or is there a workaround so that I don't have to?

You cannot modify data this way - however you can read. One could envision using another way (e.g. ADO.NET, Dapper) to modify data though - this could be a solution in cases where you rarely need to do non-read operations and still would like to stick with EF Core for your majority cases.

Also, if you truly need/want to work with heap(keyless) tables - consider ditching EF and use another way to talk to your database.

I've created an ActionButton method for the HtmlHelper. It will generate normal input button with a bit of javascript in the OnClick event that will submit the form to the specified Controller/Action.

You use the helper like that

@Html.ActionButton("MyControllerName", "MyActionName", "button text")

this will generate the following HTML

<input type="button" value="button text" onclick="this.form.action = '/MyWebsiteFolder/MyControllerName/MyActionName'; this.form.submit();">

Here is the extension method code:

VB.Net

<System.Runtime.CompilerServices.Extension()>
Function ActionButton(pHtml As HtmlHelper, pAction As String, pController As String, pRouteValues As Object, pBtnValue As String, pBtnName As String, pBtnID As String) As MvcHtmlString
    Dim urlHelperForActionLink As UrlHelper
    Dim btnTagBuilder As TagBuilder

    Dim actionLink As String
    Dim onClickEventJavascript As String

    urlHelperForActionLink = New UrlHelper(pHtml.ViewContext.RequestContext)
    If pController <> "" Then
        actionLink = urlHelperForActionLink.Action(pAction, pController, pRouteValues)
    Else
        actionLink = urlHelperForActionLink.Action(pAction, pRouteValues)
    End If
    onClickEventJavascript = "this.form.action = '" & actionLink & "'; this.form.submit();"

    btnTagBuilder = New TagBuilder("input")
    btnTagBuilder.MergeAttribute("type", "button")

    btnTagBuilder.MergeAttribute("onClick", onClickEventJavascript)

    If pBtnValue <> "" Then btnTagBuilder.MergeAttribute("value", pBtnValue)
    If pBtnName <> "" Then btnTagBuilder.MergeAttribute("name", pBtnName)
    If pBtnID <> "" Then btnTagBuilder.MergeAttribute("id", pBtnID)

    Return MvcHtmlString.Create(btnTagBuilder.ToString(TagRenderMode.Normal))
End Function

C# (the C# code is just decompiled from the VB DLL, so it can get some beautification... but time is so short :-))

public static MvcHtmlString ActionButton(this HtmlHelper pHtml, string pAction, string pController, object pRouteValues, string pBtnValue, string pBtnName, string pBtnID)
{
    UrlHelper urlHelperForActionLink = new UrlHelper(pHtml.ViewContext.RequestContext);
    bool flag = Operators.CompareString(pController, "", true) != 0;
    string actionLink;
    if (flag)
    {
        actionLink = urlHelperForActionLink.Action(pAction, pController, System.Runtime.CompilerServices.RuntimeHelpers.GetObjectValue(pRouteValues));
    }
    else
    {
        actionLink = urlHelperForActionLink.Action(pAction, System.Runtime.CompilerServices.RuntimeHelpers.GetObjectValue(pRouteValues));
    }
    string onClickEventJavascript = "this.form.action = '" + actionLink + "'; this.form.submit();";
    TagBuilder btnTagBuilder = new TagBuilder("input");
    btnTagBuilder.MergeAttribute("type", "button");
    btnTagBuilder.MergeAttribute("onClick", onClickEventJavascript);
    flag = (Operators.CompareString(pBtnValue, "", true) != 0);
    if (flag)
    {
        btnTagBuilder.MergeAttribute("value", pBtnValue);
    }
    flag = (Operators.CompareString(pBtnName, "", true) != 0);
    if (flag)
    {
        btnTagBuilder.MergeAttribute("name", pBtnName);
    }
    flag = (Operators.CompareString(pBtnID, "", true) != 0);
    if (flag)
    {
        btnTagBuilder.MergeAttribute("id", pBtnID);
    }
    return MvcHtmlString.Create(btnTagBuilder.ToString(TagRenderMode.Normal));
}

These methods have various parameters, but for the ease of use you can create some overload that take just the parameters you need.

Give name and values to those submit buttons like:

    <td>
    <input type="submit" name='mybutton' class="noborder" id="save" value="save" alt="Save" tabindex="4" />
    </td>
    <td>
    <input type="submit" name='mybutton' class="noborder" id="publish" value="publish" alt="Publish" tabindex="5" />
    </td>

and then in your php script you could check

if($_POST['mybutton'] == 'save')
{
  ///do save processing
}
elseif($_POST['mybutton'] == 'publish')
{
  ///do publish processing here
}

Available Zoom Levels

Zoom level 0 is the most zoomed out zoom level available and each integer step in zoom level halves the X and Y extents of the view and doubles the linear resolution.

Google Maps was built on a 256x256 pixel tile system where zoom level 0 was a 256x256 pixel image of the whole earth. A 256x256 tile for zoom level 1 enlarges a 128x128 pixel region from zoom level 0.

As correctly stated by bkaid, the available zoom range depends on where you are looking and the kind of map you are using:

• Road maps - seem to go up to zoom level 22 everywhere
• Hybrid and satellite maps - the max available zoom levels depend on location. Here are some examples:
• Remote regions of Antarctica: 13
• Gobi Desert: 17
• Much of the U.S. and Europe: 21
• "Deep zoom" locations: 22-23 (see bkaid's link)

Note that these values are for the Google Static Maps API which seems to give one more zoom level than the Javascript API. It appears that the extra zoom level available for Static Maps is just an upsampled version of the max-resolution image from the Javascript API.

Map Scale at Various Zoom Levels

Google Maps uses a Mercator projection so the scale varies substantially with latitude. A formula for calculating the correct scale based on latitude is:

meters_per_pixel = 156543.03392 * Math.cos(latLng.lat() * Math.PI / 180) / Math.pow(2, zoom)

Formula is from Chris Broadfoot's comment.

What you're looking for are the scales for each zoom level. Use these:

20 : 1128.497220
19 : 2256.994440
18 : 4513.988880
17 : 9027.977761
16 : 18055.955520
15 : 36111.911040
14 : 72223.822090
13 : 144447.644200
12 : 288895.288400
11 : 577790.576700
10 : 1155581.153000
9  : 2311162.307000
8  : 4622324.614000
7  : 9244649.227000
6  : 18489298.450000
5  : 36978596.910000
4  : 73957193.820000
3  : 147914387.600000
2  : 295828775.300000
1  : 591657550.500000

You can do

if($scope.test == null || $scope.test === ""){
  // null == undefined
}

if false, 0 and NaN can also be considered as false values you can just do

if($scope.test){
 //not any of the above
}

Here is javascript I wrote to do just this.

function ImageTile(parentdiv, imagediv) {
imagediv.style.position = 'absolute';

function load(image) {
    //
    // Reset to auto so that when the load happens it resizes to fit our image and that
    // way we can tell what size our image is. If we don't do that then it uses the last used
    // values to auto-size our image and we don't know what the actual size of the image is.
    //
    imagediv.style.height = "auto";
    imagediv.style.width = "auto";
    imagediv.style.top = 0;
    imagediv.style.left = 0;

    imagediv.src = image;
}

//bind load event (need to wait for it to finish loading the image)
imagediv.onload = function() {
    var vpWidth = parentdiv.clientWidth;
    var vpHeight = parentdiv.clientHeight;
    var imgWidth = this.clientWidth;
    var imgHeight = this.clientHeight;

    if (imgHeight > imgWidth) {
        this.style.height = vpHeight + 'px';
        var width = ((imgWidth/imgHeight) * vpHeight);
        this.style.width = width + 'px';
        this.style.left = ((vpWidth - width)/2) + 'px';
    } else {
        this.style.width = vpWidth + 'px';
        var height = ((imgHeight/imgWidth) * vpWidth);
        this.style.height = height + 'px';
        this.style.top = ((vpHeight - height)/2) + 'px';
    }
};

return {
    "load": load
};

}

And to use it just do something like this:

 var tile1 = ImageTile(document.documentElement, document.getElementById("tile1"));
 tile1.load(url);

I use this for a slideshow in which I have two of these "tiles" and I fade one out and the other in. The loading is done on the "tile" that is not visible to avoid the jarring visual affect of the resetting of the style back to "auto".

It often happens when you enabled multidex in you project. This can potentially slow your development process!! According doc:

multidex configuration requires significantly increased build processing time because the build system must make complex decisions about which classes must be included in the primary DEX file and which classes can be included in secondary DEX files. This means that incremental builds using multidex typically take longer and can potentially slow your development process.

but you can optimize this:

To mitigate longer incremental build times, you should use pre-dexing to reuse multidex output between builds.

If you're using Android Studio 2.3 and higher, the IDE automatically uses this feature when deploying your app to a device running Android 5.0 (API level 21) or higher.

So you need to set the minSdkVersion to 21 or higher!

But if you production version need to support minSdkVersion lower than 21, for example 19

you can use productFlavors to set minSdkVersion 21 for you dev version:

    android {
    defaultConfig {
        ...
        multiDexEnabled true
        // The default minimum API level you want to support.
        minSdkVersion 15
    }
    productFlavors {
        // Includes settings you want to keep only while developing your app.
        dev{
            //the IDE automatically uses  pre-dexing feature to mitigate longer incremental when deploying your app to a device running Android 5.0 !
            minSdkVersion 21
        }
        prod {

        }
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'),
                                                 'proguard-rules.pro'
        }
    }
}
dependencies {
    compile 'com.android.support:multidex:1.0.3'
}

I had this same issue and a couple others being reported for a existing maven project.

I had the proper dependencies in place and I could see the jar under maven dependencies, however the project was improperly brought into eclipse.

I ended up having to delete the project, clone from git again then do an import of the project as an existing maven project.

This solved the issue in this thread and several others issues I was having. More details on solution can be found here: Maven Project in Eclipse `org.springframework cannot be resolved to a type` from target path

i think it is possible by using below technique

`ts_create` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00',
`ts_update` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP

Use:

create table new_table_name 
as
select column_name,[more columns] from Existed_table;

Example:

create table dept
as
select empno, ename from emp;

If the table already exists:

insert into new_tablename select columns_list from Existed_table;

Am using like this type of font class in swift. Using font extension class.

enum FontName: String {

  case regular      = "Roboto-Regular"

}

//MARK: - Set Font Size
enum FontSize: CGFloat {
    case size = 10

}
extension UIFont {

    //MARK: - Bold Font
  class var regularFont10: UIFont {
        return UIFont(name: FontName.regular.rawValue, size:FontSize.size.rawValue )!
    }
}

For a long value you need to add the length info 'l' and 'u' for unsigned decimal integer,

as a reference of available options see sprintf

#include <stdio.h>

    int main ()
    {
      unsigned long lval = 123;
      char buffer [50];
      sprintf (buffer, "%lu" , lval );
     }

Of course, Mike's answer doesn't work if you pass the string programmatically. In this case you need to pass a attributed string and change it's style.

NSMutableAttributedString * attrString = [[NSMutableAttributedString alloc] initWithString:@"Your \nregular \nstring"];
NSMutableParagraphStyle *style = [[NSMutableParagraphStyle alloc] init];
[style setLineSpacing:4];
[attrString addAttribute:NSParagraphStyleAttributeName
                   value:style
                   range:NSMakeRange(0, attrString.length)];
_label.attributedText = attrString;

If server if down, on python 2.7 x86 windows urllib have no timeout and program go to dead lock. So use urllib2

import urllib2
import socket

def check_url( url, timeout=5 ):
    try:
        return urllib2.urlopen(url,timeout=timeout).getcode() == 200
    except urllib2.URLError as e:
        return False
    except socket.timeout as e:
        print False


print check_url("http://google.fr")  #True 
print check_url("http://notexist.kc") #False     

Already answered by @AjaxLeung, but in comments and hard to find.
For check only

lst.stream()
    .filter(x -> x > 5)
    .findFirst()
    .isPresent()

is simplified to

lst.stream()
    .anyMatch(x -> x > 5)

For simulating keyboard events in Chrome:

There is a related bug in webkit that keyboard events when initialized with initKeyboardEvent get an incorrect keyCode and charCode of 0: https://bugs.webkit.org/show_bug.cgi?id=16735

A working solution for it is posted in this SO answer.

Assembly.GetEntryAssembly()

For Linux, "ps aux | grep kafka" see if kafka properties are shown in the results. E.g. /path/to/kafka/server.properties

Curl can post binary data from a file so I have been using process substitution and taking advantage of file descriptors whenever I need to post something nasty with curl and still want access to the vars in the current shell. Something like:

curl "http://localhost:8080" \
-H "Accept: application/json" \
-H "Content-Type:application/json" \
--data @<(cat <<EOF
{
  "me": "$USER",
  "something": $(date +%s)
  }
EOF
)

This winds up looking like --data @/dev/fd/<some number> which just gets processed like a normal file. Anyway if you wanna see it work locally just run nc -l 8080 first and in a different shell fire off the above command. You will see something like:

POST / HTTP/1.1
Host: localhost:8080
User-Agent: curl/7.43.0
Accept: application/json
Content-Type:application/json
Content-Length: 43

{  "me": "username",  "something": 1465057519  }

As you can see you can call subshells and whatnot as well as reference vars in the heredoc. Happy hacking hope this helps with the '"'"'""""'''""''.

try this, calling the activity in the constructor

        }

On Ubuntu you should be able to install the necessary PDO parts from apt using sudo apt-get install php5-mysql

There is no limitation between using PDO and mysql_ simultaneously. You will however need to create two connections to your DB, one with mysql_ and one using PDO.

Here is another way to do it, if you need something flexible where you want to display help if specific params are passed, none at all or more than 1 conflicting arg:

    parser.add_argument('-e', '--event', required=False, action="store", dest="event_id",
                        help="Check mapped inventory for a specific event", default=None)
    parser.add_argument('-b', '--broker', required=False, action="store", dest="broker_id",
                        help="Check mapped inventory for a broker", default=None)

    make_updates = args.make_updates

    no_change_counter = 0
    change_counter = 0

    req_arg = bool(days) + bool(event_id) + bool(broker_id) + bool(product_id) + bool(event_keyword) + bool(metadata)
    if not req_arg:
        print("Need to specify days, broker id, event id, event keyword or past tickets full metadata")
        parser.print_help()

        parser.print_help()
        sys.exit()

Line by line

int [] v = Stream.of(line.split(",\\s+"))
  .mapToInt(Integer::parseInt)
  .toArray();

This works in IE9 (Compatibility View and Normal Mode), Firefox 17, and Chrome 23:

<table>
    <tr>
        <td style="background-image:url(untitled.png); background-position:right 0px; background-repeat:no-repeat;">
            Hello World
        </td>
    </tr>
</table>

head or tail can do it as well:

head -c X

Prints the first X bytes (not necessarily characters if it's a UTF-16 file) of the file. tail will do the same, except for the last X bytes.

This (and cut) are portable.

This example works great.

    bottom: 0;
    left: 0;
    height: $global-footer-height;
    background-color: gray;
}

There a small difference when u use rgba(255,255,255,a),background color becomes more and more lighter as the value of 'a' increase from 0.0 to 1.0. Where as when use rgba(0,0,0,a), the background color becomes more and more darker as the value of 'a' increases from 0.0 to 1.0. Having said that, its clear that both (255,255,255,0) and (0,0,0,0) make background transparent. (255,255,255,1) would make the background completely white where as (0,0,0,1) would make background completely black.

If you use Laravel and want to use Carbon the correct solution would be the following:

$start_date = Carbon::createFromFormat('Y-m-d', '2020-01-01');
$end_date = Carbon::createFromFormat('Y-m-d', '2020-01-31');

$period = new CarbonPeriod($start_date, '1 day', $end_date);

foreach ($period as $dt) {
 echo $dt->format("l Y-m-d H:i:s\n");
}

Remember to add:

• use Carbon\Carbon;
• use Carbon\CarbonPeriod;

Note: if you were on Branch1, you will with Git 2.0 (Q2 2014) be able to type:

git checkout Branch2
git rebase -

See commit 4f40740 by Brian Gesiak modocache:

rebase: allow "-" short-hand for the previous branch

Teach rebase the same shorthand as checkout and merge to name the branch to rebase the current branch on; that is, that "-" means "the branch we were previously on".

From what I know

3 one-liners

1. a = 10 if <condition>

example:

a = 10 if true # a = 10
b = 10 if false # b = nil

2. a = 10 unless <condition>

example:

a = 10 unless false # a = 10
b = 10 unless true # b = nil

3. a = <condition> ? <a> : <b>

example:

a = true ? 10 : 100 # a = 10
a = false ? 10 : 100 # a = 100

I hope it helps.

Please read this official blog entry on Google developer blog: http://android-developers.blogspot.be/2011/03/identifying-app-installations.html

Conclusion For the vast majority of applications, the requirement is to identify a particular installation, not a physical device. Fortunately, doing so is straightforward.

There are many good reasons for avoiding the attempt to identify a particular device. For those who want to try, the best approach is probably the use of ANDROID_ID on anything reasonably modern, with some fallback heuristics for legacy devices

You can try this

var lastPostDate = reader[3] == DBNull.Value ?
                                default(DateTime?): 
                                Convert.ToDateTime(reader[3]);

You can look up the constraint name in the sys.key_constraints table:

SELECT name
FROM   sys.key_constraints
WHERE  [type] = 'PK'
       AND [parent_object_id] = Object_id('dbo.Student');

If you don't care about the name, but simply want to drop it, you can use a combination of this and dynamic sql:

DECLARE @table NVARCHAR(512), @sql NVARCHAR(MAX);

SELECT @table = N'dbo.Student';

SELECT @sql = 'ALTER TABLE ' + @table 
    + ' DROP CONSTRAINT ' + name + ';'
    FROM sys.key_constraints
    WHERE [type] = 'PK'
    AND [parent_object_id] = OBJECT_ID(@table);

EXEC sp_executeSQL @sql;

If the file is large, you may not want to load it entirely into memory at once. This approach avoids that. (Of course, making a dict out of it could still take up some RAM, but it's guaranteed to be smaller than the original file.)

my_dict = {}

    if (i - 8) % 7:
        continue
    k, v = line.split("\t")[:3:2]
    my_dict[k] = v

In your case,

df = df.reindex(columns=['mean',0,1,2,3,4])

will do exactly what you want.

In my case (general form):

df = df.reindex(columns=sorted(df.columns))
df = df.reindex(columns=(['opened'] + list([a for a in df.columns if a != 'opened']) ))

If you just want to execute the shell command in your c program, you could use,

   #include <stdlib.h>

   int system(const char *command);

In your case,

system("pwd");

The issue is that there isn't an executable file called "pwd" and I'm unable to execute "echo $PWD", since echo is also a built-in command with no executable to be found.

What do you mean by this? You should be able to find the mentioned packages in /bin/

sudo find / -executable -name pwd
sudo find / -executable -name echo

Easy peasy:

var date = DateTime.Parse("14/11/2011"); // may need some Culture help here
Console.Write(date.ToString("yyyy-MM-dd"));

Take a look at DateTime.ToString() method, Custom Date and Time Format Strings and Standard Date and Time Format Strings

string customFormattedDateTimeString = DateTime.Now.ToString("yyyy-MM-dd");

You can write your php file to the action attr of form element.
At the php side you can get the form value by $_POST['element_name'].

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

The terms "background page", "popup", "content script" are still confusing you; I strongly suggest a more in-depth look at the Google Chrome Extensions Documentation.

Regarding your question if content scripts or background pages are the way to go:

Content scripts: Definitely
Content scripts are the only component of an extension that has access to the web-page's DOM.

Background page / Popup: Maybe (probably max. 1 of the two)
You may need to have the content script pass the DOM content to either a background page or the popup for further processing.

Let me repeat that I strongly recommend a more careful study of the available documentation!
That said, here is a sample extension that retrieves the DOM content on StackOverflow pages and sends it to the background page, which in turn prints it in the console:

background.js:

// Regex-pattern to check URLs against. 
// It matches URLs like: http[s]://[...]stackoverflow.com[...]
var urlRegex = /^https?:\/\/(?:[^./?#]+\.)?stackoverflow\.com/;

// A function to use as callback
function doStuffWithDom(domContent) {
    console.log('I received the following DOM content:\n' + domContent);
}

// When the browser-action button is clicked...
chrome.browserAction.onClicked.addListener(function (tab) {
    // ...check the URL of the active tab against our pattern and...
    if (urlRegex.test(tab.url)) {
        // ...if it matches, send a message specifying a callback too
        chrome.tabs.sendMessage(tab.id, {text: 'report_back'}, doStuffWithDom);
    }
});

content.js:

// Listen for messages
chrome.runtime.onMessage.addListener(function (msg, sender, sendResponse) {
    // If the received message has the expected format...
    if (msg.text === 'report_back') {
        // Call the specified callback, passing
        // the web-page's DOM content as argument
        sendResponse(document.all[0].outerHTML);
    }
});

manifest.json:

{
  "manifest_version": 2,
  "name": "Test Extension",
  "version": "0.0",
  ...

  "background": {
    "persistent": false,
    "scripts": ["background.js"]
  },
  "content_scripts": [{
    "matches": ["*://*.stackoverflow.com/*"],
    "js": ["content.js"]
  }],
  "browser_action": {
    "default_title": "Test Extension"
  },

  "permissions": ["activeTab"]
}

changing implementation 'com.android.support:appcompat-v7:27+' to implementation 'com.android.support:appcompat-v7:+' worked for me

I am using Intellij 2019 CE, with Kotlin

What worked for me is:

GoTo

setting.gradle

1. change the name in it.
2. go to the app root folder which you want to change and refactor--> rename it.
3. close the android studio.
4. browse to the folder and change the name
5. start android studio again.
6. do the gradle sync.

And you are done!

I came across this solution but this does not really fit my need. So I digged a bit in the d3 source code. I personally would recommend to do it like d3.scale does.

So here you scale the domain to the range. The advantage is that you can flip signs to your target range. This is useful since the y axis on a computer screen goes top down so large values have a small y.

public class Rescale {
    private final double range0,range1,domain0,domain1;

    public Rescale(double domain0, double domain1, double range0, double range1) {
        this.range0 = range0;
        this.range1 = range1;
        this.domain0 = domain0;
        this.domain1 = domain1;
    }

    private double interpolate(double x) {
        return range0 * (1 - x) + range1 * x;
    }

    private double uninterpolate(double x) {
        double b = (domain1 - domain0) != 0 ? domain1 - domain0 : 1 / domain1;
        return (x - domain0) / b;
    }

    public double rescale(double x) {
        return interpolate(uninterpolate(x));
    }
}

And here is the test where you can see what I mean

public class RescaleTest {

    @Test
    public void testRescale() {
        Rescale r;
        r = new Rescale(5,7,0,1);
        Assert.assertTrue(r.rescale(5) == 0);
        Assert.assertTrue(r.rescale(6) == 0.5);
        Assert.assertTrue(r.rescale(7) == 1);

        r = new Rescale(5,7,1,0);
        Assert.assertTrue(r.rescale(5) == 1);
        Assert.assertTrue(r.rescale(6) == 0.5);
        Assert.assertTrue(r.rescale(7) == 0);

        r = new Rescale(-3,3,0,1);
        Assert.assertTrue(r.rescale(-3) == 0);
        Assert.assertTrue(r.rescale(0) == 0.5);
        Assert.assertTrue(r.rescale(3) == 1);

        r = new Rescale(-3,3,-1,1);
        Assert.assertTrue(r.rescale(-3) == -1);
        Assert.assertTrue(r.rescale(0) == 0);
        Assert.assertTrue(r.rescale(3) == 1);
    }
}

I think you're reading those stats incorrectly. They show that Python is up to about 400 times slower than C++ and with the exception of a single case, Python is more of a memory hog. When it comes to source size though, Python wins flat out.

My experiences with Python show the same definite trend that Python is on the order of between 10 and 100 times slower than C++ when doing any serious number crunching. There are many reasons for this, the major ones being: a) Python is interpreted, while C++ is compiled; b) Python has no primitives, everything including the builtin types (int, float, etc.) are objects; c) a Python list can hold objects of different type, so each entry has to store additional data about its type. These all severely hinder both runtime and memory consumption.

This is no reason to ignore Python though. A lot of software doesn't require much time or memory even with the 100 time slowness factor. Development cost is where Python wins with the simple and concise style. This improvement on development cost often outweighs the cost of additional cpu and memory resources. When it doesn't, however, then C++ wins.

Run cmd and then run node server.js. In your example, you are trying to use the REPL to run your command, which is not going to work. The ellipsis is node.js expecting more tokens before closing the current scope (you can type code in and run it on the fly here)

[I was going to post this as a comment on John Cromartie's post, but didn't realize you couldn't use formatting in a comment.]

I agree. Dropping it to a shell with os.execute() will definitely work but in general making shell calls is expensive. Wrapping some C code will be much quicker at run-time. In C/C++ on a Linux system, you could use:

static int lua_sleep(lua_State *L)
{
    int m = static_cast<int> (luaL_checknumber(L,1));
    usleep(m * 1000); 
    // usleep takes microseconds. This converts the parameter to milliseconds. 
    // Change this as necessary. 
    // Alternatively, use 'sleep()' to treat the parameter as whole seconds. 
    return 0;
}

Then, in main, do:

lua_pushcfunction(L, lua_sleep);
lua_setglobal(L, "sleep");

where "L" is your lua_State. Then, in your Lua script called from C/C++, you can use your function by calling:

sleep(1000) -- Sleeps for one second

You can use the Median of Medians algorithm to find median of an unsorted array in linear time.

If you are using Auto Layout then you can do it on the Story board.

Add a height constraint to the text field, then change the height constraint constant to any desired value. Steps are shown below:

Step 1: Create a height constraint for the text field

Step 2: Select Height Constraint

Step 3: Change Height Constraint's constant value

Method that will work. The way it is used above will not work.

declare @str varchar(50)='79136'

select 
  case 
    when  @str LIKE replicate('[0-9]',LEN(@str)) then 1 
    else 0 
  end

declare @str2 varchar(50)='79D136'

select 
  case 
    when  @str2 LIKE replicate('[0-9]',LEN(@str)) then 1 
    else 0 
  end

Yes, that is supported.

Check the documentation provided here for the supported keywords inside method names.

You can just define the method in the repository interface without using the @Query annotation and writing your custom query. In your case it would be as followed:

List<Inventory> findByIdIn(List<Long> ids);

I assume that you have the Inventory entity and the InventoryRepository interface. The code in your case should look like this:

The Entity

@Entity
public class Inventory implements Serializable {

  private static final long serialVersionUID = 1L;

  private Long id;

  // other fields
  // getters/setters

}

The Repository

@Repository
@Transactional
public interface InventoryRepository extends PagingAndSortingRepository<Inventory, Long> {

  List<Inventory> findByIdIn(List<Long> ids);

}

.last { border-right: none

.last { border-right: none !important; }

I like to run the following:

git commit -am "message";git push

dir(sys) says no. len(sys.argv) works, but in Python it is better to ask for forgiveness than permission, so

#!/usr/bin/python
import sys
try:
    in_file = open(sys.argv[1], "r")
except:
    sys.exit("ERROR. Can't read supplied filename.")
text = in_file.read()
print(text)
in_file.close()

works fine and is shorter.

If you're going to exit anyway, this would be better:

#!/usr/bin/python
import sys
text = open(sys.argv[1], "r").read()
print(text)

I'm using print() so it works in 2.7 as well as Python 3.

There's at least one situation in which you want sys.stdout instead of print.

When you want to overwrite a line without going to the next line, for instance while drawing a progress bar or a status message, you need to loop over something like

Note carriage return-> "\rMy Status Message: %s" % progress

And since print adds a newline, you are better off using sys.stdout.

Nothing much new to add, but I have had a lot of real-world experience in GIS and geocoding from a previous job. Here is what I remember:

If it is a "every once in a while" need in your application, I would definitely recommend the Google or Yahoo Geocoding APIs, but be careful to read their licensing terms.

I know that the Google Maps API in general is easy to license for even commercial web pages, but can't be used in a pay-to-access situation. In other words you can use it to advertise or provide a service that drives ad revenue, but you can't charge people to acess your site or even put it behind a password system.

Despite these restrictions, they are both excellent choices because they frequently update their street databases. Most of the free backend tools and libraries use Census and TIGER road data that is updated infrequently, so you are less likely to successfully geocode addresses in rapidly growing areas or new subdivisions.

Most of the services also restrict the number of geocoding queries you can make per day, so it's OK to look up addresses of, say, new customers who get added to your database, but if you run a batch job that feeds thousands of addresses from your database into the geocoder, you're going to get shutoff.

I don't think this one has been mentioned yet, but ESRI has ArcWeb web services that include geocoding, although they aren't very cheap. Last time I used them it cost around 1.5cents per lookup, but you had to prepay a certain amount to get started. Again the major advantage is that the road data they use is kept up to date in a timely manner and you can use the data in commercial situations that Google doesn't allow. The ArcWeb service will also serve up high-resolution satellite and aerial photos a la Google Maps, again priced per request.

If you want to roll your own or have access to much more accurate data, you can purchase subscriptions to GIS data from companies like TeleAtlas, but that ain't cheap. You can buy only a state or county worth of data if your needs are extremely local. There are several tiers of data - GIS features only, GIS plus detailed streets, all that plus geocode data, all of that plus traffic flow/direction/speed limits for routing. Of course, the price goes up as you go up the tiers.

Finally, the Wikipedia article on Geocoding has some good information on the algorithms and techniques. Even if you aren't doing it in your own code, it's useful to know what kind of errors and accuracy you can expect from various kinds of data sources.

The technical limitations with using PUT and DELETE requests does not lie with PHP or Apache2; it is instead on the burden of the browser to sent those types of requests.

Simply putting <form action="" method="PUT"> will not work because there are no browsers that support that method (and they would simply default to GET, treating PUT the same as it would treat gibberish like FDSFGS). Sadly those HTTP verbs are limited to the realm of non-desktop application browsers (ie: web service consumers).

It's called String#start_with?, not String#startswith: In Ruby, the names of boolean-ish methods end with ? and the words in method names are separated with an _. Not sure where the s went, personally, I'd prefer String#starts_with? over the actual String#start_with?

You need to cast it to a string (not an array of string) since it's a single value.

var cellValue = (string)(excelWorksheet.Cells[10, 2] as Excel.Range).Value;

mkdirs() will create the specified directory path in its entirety where mkdir() will only create the bottom most directory, failing if it can't find the parent directory of the directory it is trying to create.

In other words mkdir() is like mkdir and mkdirs() is like mkdir -p.

For example, imagine we have an empty /tmp directory. The following code

new File("/tmp/one/two/three").mkdirs();

would create the following directories:

• /tmp/one
• /tmp/one/two
• /tmp/one/two/three

Where this code:

new File("/tmp/one/two/three").mkdir();

would not create any directories - as it wouldn't find /tmp/one/two - and would return false.

If you are using IIS 7.5 or later you can generate the machine key from IIS and save it directly to your web.config, within the web farm you then just copy the new web.config to each server.

1. Open IIS manager.
2. If you need to generate and save the MachineKey for all your applications select the server name in the left pane, in that case you will be modifying the root web.config file (which is placed in the .NET framework folder). If your intention is to create MachineKey for a specific web site/application then select the web site / application from the left pane. In that case you will be modifying the web.config file of your application.
3. Double-click the Machine Key icon in ASP.NET settings in the middle pane:
4. MachineKey section will be read from your configuration file and be shown in the UI. If you did not configure a specific MachineKey and it is generated automatically you will see the following options:
5. Now you can click Generate Keys on the right pane to generate random MachineKeys. When you click Apply, all settings will be saved in the web.config file.

Full Details can be seen @ Easiest way to generate MachineKey – Tips and tricks: ASP.NET, IIS and .NET development…

.loc accept row and column selectors simultaneously (as do .ix/.iloc FYI) This is done in a single pass as well.

You just need to add disabled as option attribute

<option disabled>select one option</option>

In your comparator factory class, do something like this:

 private static final Comparator<String> MYSTRING_COMPARATOR = new Comparator<String>() {
    @Override
    public int compare(String s1, String s2) {
      return s1.compareToIgnoreCase(s2);
    }
  };

  public static Comparator<String> getMyStringComparator() {
    return MYSTRING_COMPARATOR;

This uses the compare to method which is case insensitive (why write your own). This way you can use Collections sort like this:

List<String> myArray = new ArrayList<String>();
//fill your array here    
Collections.sort(MyArray, MyComparators. getMyStringComparator());

I had this issue using Vesta CP and for me, the trick was remove .htaccess and try to access to any file again.

That resulted on regeneration of .htaccess file and then I was able to access to my files.

While LIKE is suitable for this case, a more general purpose solution is to use instr, which doesn't require characters in the search string to be escaped. Note: instr is available starting from Sqlite 3.7.15.

SELECT *
  FROM TABLE  
 WHERE instr(column, 'cats') > 0;

Also, keep in mind that LIKE is case-insensitive, whereas instr is case-sensitive.

I would not change the constraints, instead, you can insert a new record in the table_1 with the primary key (id_no = 7008255601088). This is nothing but a duplicate row of the id_no = 8008255601088. so now patient_address with the foreign key constraint (id_no = 8008255601088) can be updated to point to the record with the new ID(ID which needed to be updated), which is updating the id_no to id_no =7008255601088.

Then you can remove the initial primary key row with id_no =7008255601088.

Three steps include:

1. Insert duplicate row for new id_no
2. Update Patient_address to point to new duplicate row
3. Remove the row with old id_no

1. Open Terminal type geany .bashrc
2. Go to the top and paste this
   export CLASSPATH=$CLASSPATH:/web/apache-tomcat-8.5.39/lib/servlet-api.jar
3. Now save and close
4. Try running the program now.

Others have adequately explained what a static library is, but I'd like to point out some of the caveats of using static libraries, at least on Windows:

• Singletons: If something needs to be global/static and unique, be very careful about putting it in a static library. If multiple DLLs are linked against that static library they will each get their own copy of the singleton. However, if your application is a single EXE with no custom DLLs, this may not be a problem.

• Unreferenced code removal: When you link against a static library, only the parts of the static library that are referenced by your DLL/EXE will get linked into your DLL/EXE.

  For example, if mylib.lib contains a.obj and b.obj and your DLL/EXE only references functions or variables from a.obj, the entirety of b.obj will get discarded by the linker. If b.obj contains global/static objects, their constructors and destructors will not get executed. If those constructors/destructors have side effects, you may be disappointed by their absence.

  Likewise, if the static library contains special entrypoints you may need to take care that they are actually included. An example of this in embedded programming (okay, not Windows) would be an interrupt handler that is marked as being at a specific address. You also need to mark the interrupt handler as an entrypoint to make sure it doesn't get discarded.

  Another consequence of this is that a static library may contain object files that are completely unusable due to unresolved references, but it won't cause a linker error until you reference a function or variable from those object files. This may happen long after the library is written.

• Debug symbols: You may want a separate PDB for each static library, or you may want the debug symbols to be placed in the object files so that they get rolled into the PDB for the DLL/EXE. The Visual C++ documentation explains the necessary options.

• RTTI: You may end up with multiple type_info objects for the same class if you link a single static library into multiple DLLs. If your program assumes that type_info is "singleton" data and uses &typeid() or type_info::before(), you may get undesirable and surprising results.

CORS issue can be simply resolved by following this:

Create a new shortcut of Google Chrome(update browser installation path accordingly) with following value:

An easy way to serialize Enum is using @JsonFormat annotation. @JsonFormat can configure the serialization of a Enum in three ways.

@JsonFormat.Shape.STRING
public Enum OrderType {...}

uses OrderType::name as the serialization method. Serialization of OrderType.TypeA is “TYPEA”

@JsonFormat.Shape.NUMBER
Public Enum OrderTYpe{...}

uses OrderType::ordinal as the serialization method. Serialization of OrderType.TypeA is 1

@JsonFormat.Shape.OBJECT
Public Enum OrderType{...}

treats OrderType as a POJO. Serialization of OrderType.TypeA is {"id":1,"name":"Type A"}

JsonFormat.Shape.OBJECT is what you need in your case.

A little more complicated way is your solution, specifying a serializer for the Enum.

Scripts are loaded in the order you have defined them in the HTML.

Therefore if you first load:

<script type="text/javascript" src="./javascript.js"></script>

without loading jQuery first, then $ is not defined.

You need to first load jQuery so that you can use it.

I would also recommend placing your scripts at the bottom of your HTML for performance reasons.

I ran into this issue today. Here is my hacky solution.

I needed a fixed position element to transition up by 100 pixels as it loaded.

var delay = (ms) => new Promise(res => setTimeout(res, ms));
async function animateView(startPosition,elm){
  for(var i=0; i<101; i++){
    elm.style.top = `${(startPosition-i)}px`;
    await delay(1);
  }
}

here's a very simple hash table implementation in java. in only implements put() and get(), but you can easily add whatever you like. it relies on java's hashCode() method that is implemented by all objects. you could easily create your own interface,

interface Hashable {
  int getHash();
}

and force it to be implemented by the keys if you like.

public class Hashtable<K, V> {
    private static class Entry<K,V> {
        private final K key;
        private final V val;

        Entry(K key, V val) {
            this.key = key;
            this.val = val;
        }
    }

    private static int BUCKET_COUNT = 13;

    @SuppressWarnings("unchecked")
    private List<Entry>[] buckets = new List[BUCKET_COUNT];

    public Hashtable() {
        for (int i = 0, l = buckets.length; i < l; i++) {
            buckets[i] = new ArrayList<Entry<K,V>>();
        }
    }

    public V get(K key) {
        int b = key.hashCode() % BUCKET_COUNT;
        List<Entry> entries = buckets[b];
        for (Entry e: entries) {
            if (e.key.equals(key)) {
                return e.val;
            }
        }
        return null;
    }

    public void put(K key, V val) {
        int b = key.hashCode() % BUCKET_COUNT;
        List<Entry> entries = buckets[b];
        entries.add(new Entry<K,V>(key, val));
    }
}

This Status Code 500 is an Internal Server Error. This code indicates that a part of the server (for example, a CGI program) has crashed or encountered a configuration error.

i think the problem does'nt lie on your side, but rather on the side of the Http server. the resources you used to access may have been moved or get corrupted, or its configuration just may have altered or spoiled

Same Problem I had... I was writing all the script in a seperate file and was adding it through tag into the end of the HTML file after body tag. After moving the the tag inside the body tag it works fine. before :

</body>
<script>require('../script/viewLog.js')</script>

after :

<script>require('../script/viewLog.js')</script>
</body>

mvn eclipse:clean

then from eclipse: "Maven Update Project" does the trick!

You are getting this error because the value cannot be found in the range. String or integer doesn't matter. Best thing to do in my experience is to do a check first to see if the value exists.

I used CountIf below, but there is lots of different ways to check existence of a value in a range.

Public Sub test()

Dim rng As Range
Dim aNumber As Long

aNumber = 666

Set rng = Sheet5.Range("B16:B615")

    If Application.WorksheetFunction.CountIf(rng, aNumber) > 0 Then

        rowNum = Application.WorksheetFunction.Match(aNumber, rng, 0)

    Else
        MsgBox aNumber & " does not exist in range " & rng.Address
    End If

End Sub

ALTERNATIVE WAY

Public Sub test()
    Dim rng As Range
    Dim aNumber As Variant
    Dim rowNum As Long

    aNumber = "2gg"

    Set rng = Sheet5.Range("B1:B20")

    If Not IsError(Application.Match(aNumber, rng, 0)) Then
        rowNum = Application.Match(aNumber, rng, 0)
        MsgBox rowNum
    Else
        MsgBox "error"
    End If
End Sub

OR

Public Sub test()
    Dim rng As Range
    Dim aNumber As Variant

A simple solution might be to just store the drawable id in a temporary variable. I'm not sure how practical this would be for your situation but it's definitely a quick fix.

Definitely avoid using eval to do something like this, or you will open yourself to XSS (Cross-Site Scripting) vulnerabilities.

For example, if you were to use the eval solutions proposed here, a nefarious user could send a link to their victim that looked like this:

http://yoursite.com/foo.html?func=function(){alert('Im%20In%20Teh%20Codez');}

And their javascript, not yours, would get executed. This code could do something far worse than just pop up an alert of course; it could steal cookies, send requests to your application, etc.

So, make sure you never eval untrusted code that comes in from user input (and anything on the query string id considered user input). You could take user input as a key that will point to your function, but make sure that you don't execute anything if the string given doesn't match a key in your object. For example:

// set up the possible functions:
var myFuncs = {
  func1: function () { alert('Function 1'); },
  func2: function () { alert('Function 2'); },
  func3: function () { alert('Function 3'); },
  func4: function () { alert('Function 4'); },
  func5: function () { alert('Function 5'); }
};
// execute the one specified in the 'funcToRun' variable:
myFuncs[funcToRun]();

This will fail if the funcToRun variable doesn't point to anything in the myFuncs object, but it won't execute any code.

You only have to edit your profile file like this:

sudo su
vim ~/.profile

and put this at the end of the file:

export ANDROID_HOME=/home/(user name)/Android/Sdk
export PATH=$PATH:/tools
export PATH=$PATH:/platform-tools

Save and close the file and do:

cd ~
source .profile

now if you do:

echo $ANDROID_HOME

it should show you something like this:

/home/(user name)/Android/Sdk

SELECT E.CaseNum, E.FileNum, E.ActivityNum, E.Grade, V.Score
FROM Evaluation E
INNER JOIN Value V
ON E.CaseNum = V.CaseNum AND E.FileNum = V.FileNum AND E.ActivityNum = V.ActivityNum

First you can write the code:

{    [self.tableView setSeparatorStyle:UITableViewCellSeparatorStyleNone];}

after that

{    #define cellHeight 80 // You can change according to your req.<br>
     #define cellWidth 320 // You can change according to your req.<br>

    -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath  *)indexPath
    {
         UIImageView *imgView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"seprater_line.png"]];
        imgView.frame = CGRectMake(0, cellHeight, cellWidth, 1);
        [customCell.contentView addSubview:imgView];
         return  customCell;

     }
}

public void EndTask(string taskname)
{
      string processName = taskname.Replace(".exe", "");

      foreach (Process process in Process.GetProcessesByName(processName))
      {
          process.Kill();
      }
}

//EndTask("notepad");

Summary: no matter if the name contains .exe, the process will end. You don't need to "leave off .exe from process name", It works 100%.

You have to retrieve it from the HOST header.

var host = req.get('host');

It is optional with HTTP 1.0, but required by 1.1. And, the app can always impose a requirement of its own.

If this is for supporting cross-origin requests, you would instead use the Origin header.

var origin = req.get('origin');

Note that some cross-origin requests require validation through a "preflight" request:

req.options('/route', function (req, res) {
    var origin = req.get('origin');
    // ...
});

If you're looking for the client's IP, you can retrieve that with:

var userIP = req.socket.remoteAddress;

• message.socket.
• socket.remoteAddress

Note that, if your server is behind a proxy, this will likely give you the proxy's IP. Whether you can get the user's IP depends on what info the proxy passes along. But, it'll typically be in the headers as well.

Adding a refresh in meta inside noscript is not a good idea.

1. Because noscript tag is not XHTML compliant

2. The attribute value "Refresh" is nonstandard, and should not be used. "Refresh" takes the control of a page away from the user. Using "Refresh" will cause a failure in W3C's Web Content Accessibility Guidelines --- Reference http://www.w3schools.com/TAGS/att_meta_http_equiv.asp.

Short version of Franci's answer:

for(Iterator<String> iter = json.keys();iter.hasNext();) {
    String key = iter.next();
    ...
}

Don't put the environment configuration in catalina.bat/catalina.sh. Instead you should create a new file in CATALINA_BASE\bin\setenv.bat to keep your customizations separate of tomcat installation.

A jar is merely a container. It is a file archive a la tar. While a jar may have interesting information contained within it's META-INF hierarchy, it has no obligation to specify the vintage of the classes within it's contents. For that, one must examine the class files therein.

As as Peter Lawrey mentioned in comment to the original question, you can't necessarily know which JDK release built a given class file, but you can find out the byte code class version of the class file contained in a jar.

Yes, this kinda sucks, but the first step is to extract one or more classes from the jar. For example:

$ jar xf log4j-1.2.15.jar

On Linux, Mac OS X or Windows with Cygwin installed, the file(1) command knows the class version.

$ file ./org/apache/log4j/Appender.class
./org/apache/log4j/Appender.class: compiled Java class data, version 45.3

Or alternatively, using javap from the JDK as @jikes.thunderbolt aptly points out:

$ javap -v ./org/apache/log4j/Appender.class | grep major
 major version: 45

For Windows environments without either file or grep

> javap -v ./org/apache/log4j/Appender.class | findstr major
 major version: 45

FWIW, I will concur that javap will tell a whole lot more about a given class file than the original question asked.

Anyway, a different class version, for example:

$ file ~/bin/classes/P.class
/home/dave/bin/classes/P.class: compiled Java class data, version 50.0

The class version major number corresponds to the following Java JDK versions:

• 45.3 = Java 1.1
• 46 = Java 1.2
• 47 = Java 1.3
• 48 = Java 1.4
• 49 = Java 5
• 50 = Java 6
• 51 = Java 7
• 52 = Java 8
• 53 = Java 9
• 54 = Java 10
• 55 = Java 11
• 56 = Java 12
• 57 = Java 13
• 58 = Java 14

Late to the party, here is a short one. It has these limitations:

• It only does a plain string sort of the SubItems' Texts
• It uses the ListView's Tag
• It assumes all clicked columns will be filled

You can register & unregister any ListView to its service; make sure the Sorting is set to None..:

public static class LvSort
{
    static List<ListView> LVs = new List<ListView>();
    public static void registerLV(ListView lv)
    {
        if (!LVs.Contains(lv) && lv is ListView)
        {
            LVs.Add(lv);
            lv.ColumnClick +=Lv_ColumnClick;
        }
    }
    public static void unRegisterLV(ListView lv)
    {
        if (LVs.Contains(lv) && lv is ListView)
        {
            LVs.Remove(lv);
            lv.ColumnClick -=Lv_ColumnClick;
        }
    }

    private static void Lv_ColumnClick(object sender, ColumnClickEventArgs e)
    {
        ListView lv = sender as ListView;
        if (lv == null) return;
        int c = e.Column;
        bool asc = (lv.Tag == null) || ( lv.Tag.ToString() != c+"");
        var items = lv.Items.Cast<ListViewItem>().ToList();
        var sorted =  asc ? items.OrderByDescending(x => x.SubItems[c].Text).ToList() :
                            items.OrderBy(x => x.SubItems[c].Text).ToList();
        lv.Items.Clear();
        lv.Items.AddRange(sorted.ToArray());
        if (asc) lv.Tag = c+""; else lv.Tag = null;
    }
}

To register simply do..:

public Form1()
{
    InitializeComponent();
    LvSort.registerLV(yourListView1);
}

Update:

Here is a slightly extended version that will let you sort all sorts of data types using any sorting rule you come up with. All you need to do is write a special string conversion for your data, add it to the function list and mark your columns. To do so simply put the column names appended with a marker string in the columns' Tags.

I have added one for sorting DataTimes and one for integers.

This version will also sort jagged ListViews, i.e. those with different numbers of subitems.

public static class LvCtl
{
    static List<ListView> LVs = new List<ListView>();

    delegate string  StringFrom (string s);

    static Dictionary<string, StringFrom> funx = new Dictionary<string, StringFrom>();

    public static void registerLV(ListView lv)
    {
        if (!LVs.Contains(lv) && lv is ListView)
        {
            LVs.Add(lv);
            lv.ColumnClick +=Lv_ColumnClick;

            funx.Add("", stringFromString);
            for (int i = 0; i <  lv.Columns.Count; i++)
            {
                if (lv.Columns[i].Tag == null) continue;
                string n = lv.Columns[i].Tag.ToString();
                if (n == "") continue;
                if (n.Contains("__date")) funx.Add(n, stringFromDate);
                if (n.Contains("__int")) funx.Add(n, stringFromInt);
                else funx.Add(n, stringFromString);
            }

        }
    }

    static string stringFromString(string s)
    {
        return s;
    }
    static string stringFromInt(string s)
    {
        int i = 0;
        int.TryParse(s, out i);
        return i.ToString("00000") ;
    }
    static string stringFromDate(string s)
    {
        DateTime dt = Convert.ToDateTime(s);
        return dt.ToString("yyyy.MM.dd HH.mm.ss");
    }

    private static void Lv_ColumnClick(object sender, ColumnClickEventArgs e)
    {
        ListView lv = sender as ListView;
        if (lv == null) return;


        int c = e.Column;
        string nt = lv.Columns[c].Tag != null ? lv.Columns[c].Tag.ToString() : "";
        string n = nt.Replace("__", "§").Split('§')[0];

        bool asc = (lv.Tag == null) || ( lv.Tag.ToString() != c+"");
        var items = lv.Items.Cast<ListViewItem>().ToList();
        var sorted =  asc?
            items.OrderByDescending(x =>  funx[nt]( c < x.SubItems.Count ?
                                    x.SubItems[c].Text: "")).ToList() :
            items.OrderBy(x => funx[nt](c < x.SubItems.Count ?
                          x.SubItems[c].Text : "")).ToList();
        lv.Items.Clear();
        lv.Items.AddRange(sorted.ToArray());
        if (asc) lv.Tag = c+""; else lv.Tag = null;
    }

    public static void unRegisterLV(ListView lv)
    {
        if (LVs.Contains(lv) && lv is ListView)
        {
            LVs.Remove(lv);
            lv.ColumnClick -=Lv_ColumnClick;
        }
    }
}

Are you aware of <button> elements? <button> elements can be styled just like <div> elements and can have type="submit" so they submit the form without javascript:

<form action="whatever.html" method="post">  
    <button name="mysubmitbutton" id="mysubmitbutton" type="submit" class="customButton">  
    Button Text
    </button>  
</form>  

Using a <button> is also more semantic, whereas <div> is very generic. You get the following benefits for free:

• JavaScript is not necessary to submit the form
• Accessibility tools, e.g. screen readers, will (correctly) treat it as a button and not part of the normal text flow
• <button type="submit"> becomes a "default" button, which means the return key will automatically submit the form. You can't do this with a <div>, you'd have to add a separate keydown handler to the <form> element.

There's one (non-) caveat: a <button> can only have phrasing content, though it's unlikely anyone would need any other type of content when using the element to submit a form.

Looking at this official google link: Youtube Live encoder settings, bitrates and resolutions they have this table:

                   240p       360p        480p        720p        1080p
Resolution      426 x 240   640 x 360   854x480     1280x720    1920x1080
Video Bitrates                   
Maximum         700 Kbps    1000 Kbps   2000 Kbps   4000 Kbps   6000 Kbps
Recommended     400 Kbps    750 Kbps    1000 Kbps   2500 Kbps   4500 Kbps
Minimum         300 Kbps    400 Kbps    500 Kbps    1500 Kbps   3000 Kbps

It would appear as though this is the case, although the numbers dont sync up to the google table above:

// the bitrates, video width and file names for this clip
      bitrates: [
        { url: "bbb-800.mp4", width: 480, bitrate: 800 }, //360p video
        { url: "bbb-1200.mp4", width: 720, bitrate: 1200 }, //480p video
        { url: "bbb-1600.mp4", width: 1080, bitrate: 1600 } //720p video
      ],

One can create an empty array, fill it (otherwise map will skip it) and then map indexes to values:

Array(8).fill().map((_, i) => i * i);

First of all shuffling is the process of transfering data from the mappers to the reducers, so I think it is obvious that it is necessary for the reducers, since otherwise, they wouldn't be able to have any input (or input from every mapper). Shuffling can start even before the map phase has finished, to save some time. That's why you can see a reduce status greater than 0% (but less than 33%) when the map status is not yet 100%.

Sorting saves time for the reducer, helping it easily distinguish when a new reduce task should start. It simply starts a new reduce task, when the next key in the sorted input data is different than the previous, to put it simply. Each reduce task takes a list of key-value pairs, but it has to call the reduce() method which takes a key-list(value) input, so it has to group values by key. It's easy to do so, if input data is pre-sorted (locally) in the map phase and simply merge-sorted in the reduce phase (since the reducers get data from many mappers).

Partitioning, that you mentioned in one of the answers, is a different process. It determines in which reducer a (key, value) pair, output of the map phase, will be sent. The default Partitioner uses a hashing on the keys to distribute them to the reduce tasks, but you can override it and use your own custom Partitioner.

A great source of information for these steps is this Yahoo tutorial (archived).

A nice graphical representation of this is the following (shuffle is called "copy" in this figure):

Note that shuffling and sorting are not performed at all if you specify zero reducers (setNumReduceTasks(0)). Then, the MapReduce job stops at the map phase, and the map phase does not include any kind of sorting (so even the map phase is faster).

UPDATE: Since you are looking for something more official, you can also read Tom White's book "Hadoop: The Definitive Guide". Here is the interesting part for your question.
Tom White has been an Apache Hadoop committer since February 2007, and is a member of the Apache Software Foundation, so I guess it is pretty credible and official...

Right click on a file → Ignore → Ignore everything beneath.

If the Ignore option is grayed out then:

1. Stage a file first
2. Right click → Stop Tracking
3. That file will appear in the pane below with a question mark → Right click on it→ Ignore

Construct some data

df <- data.frame( name=c("John", "Adam"), date=c(3, 5) )

Extract exact matches:

subset(df, date==3)

  name date
1 John    3

Extract matches in range:

subset(df, date>4 & date<6)

  name date
2 Adam    5

The following syntax produces identical results:

df[df$date>4 & df$date<6, ]

  name date
2 Adam    5

Your class shoud look something like this:

class Something {     int[] array; //global array, replace type of course     void function1() {        array = new int[10]; //let say you declare it here that will be 10 integers in size     }     void function2() {        array[0] = 12; //assing value at index 0 to 12.     } } 

That way you array will be accessible in both functions. However, you must be careful with global stuff, as you can quickly overwrite something.

As Dumb Guy points out, it's important to note whether the array starts at zero and is sequential. Since you can make assignments to and unset non-contiguous indices ${#array[@]} is not always the next item at the end of the array.

$ array=(a b c d e f g h)
$ array[42]="i"
$ unset array[2]
$ unset array[3]
$ declare -p array     # dump the array so we can see what it contains
declare -a array='([0]="a" [1]="b" [4]="e" [5]="f" [6]="g" [7]="h" [42]="i")'
$ echo ${#array[@]}
7
$ echo ${array[${#array[@]}]}
h

Here's how to get the last index:

$ end=(${!array[@]})   # put all the indices in an array
$ end=${end[@]: -1}    # get the last one
$ echo $end
42

That illustrates how to get the last element of an array. You'll often see this:

$ echo ${array[${#array[@]} - 1]}
g

As you can see, because we're dealing with a sparse array, this isn't the last element. This works on both sparse and contiguous arrays, though:

$ echo ${array[@]: -1}
i

Based on the answer by 'Cassio Borghi'. With this method, there is no need to change the XAML at all.

        DataGridTextColumn colNameStatus2 = new DataGridTextColumn();
        colNameStatus2.Header = "Status";
        colNameStatus2.MinWidth = 100;
        colNameStatus2.Binding = new Binding("Status");
        grdComputer_Servives.Columns.Add(colNameStatus2);

        Style style = new Style(typeof(TextBlock));
        Trigger running = new Trigger() { Property = TextBlock.TextProperty, Value = "Running" };
        Trigger stopped = new Trigger() { Property = TextBlock.TextProperty, Value = "Stopped" };

        stopped.Setters.Add(new Setter() { Property = TextBlock.BackgroundProperty, Value = Brushes.Blue });
        running.Setters.Add(new Setter() { Property = TextBlock.BackgroundProperty, Value = Brushes.Green });

        style.Triggers.Add(running);
        style.Triggers.Add(stopped);

        colNameStatus2.ElementStyle = style;

Found a way to enable cors without importing any 'cors' library. It also works with Typescript and tested it in chrome version 81.0.

exports.createOrder = functions.https.onRequest((req, res) => {
// browsers like chrome need these headers to be present in response if the api is called from other than its base domain
  res.set("Access-Control-Allow-Origin", "*"); // you can also whitelist a specific domain like "http://127.0.0.1:4000"
  res.set("Access-Control-Allow-Headers", "Content-Type");

  // your code starts here

  //send response
  res.status(200).send();
});

<body> 
    <form method="post">

    </form>
</body>

I'd suggest to use http://docopt.org/. There's a scala-port but the Java implementation https://github.com/docopt/docopt.java works just fine and seems to be better maintained. Here's an example:

import org.docopt.Docopt

import scala.collection.JavaConversions._
import scala.collection.JavaConverters._

val doc =
"""
Usage: my_program [options] <input>

Options:
 --sorted   fancy sorting
""".stripMargin.trim

//def args = "--sorted test.dat".split(" ").toList
var results = new Docopt(doc).
  parse(args()).
  map {case(key, value)=>key ->value.toString}

val inputFile = new File(results("<input>"))
val sorted = results("--sorted").toBoolean

This is my JavaScript implementation of Algorithm P (Polar method for normal deviates) from Section 3.4.1 of Donald Knuth's book The Art of Computer Programming:

function normal_random(mean,stddev)
{
    var V1
    var V2
    var S
    do{
        var U1 = Math.random() // return uniform distributed in [0,1[
        var U2 = Math.random()
        V1 = 2*U1-1
        V2 = 2*U2-1
        S = V1*V1+V2*V2
    }while(S >= 1)
    if(S===0) return 0
    return mean+stddev*(V1*Math.sqrt(-2*Math.log(S)/S))
}

You need to give the absolute pathname to where the file exists.

        File file = new File("C:\\Users\\User\\Documents\\Workspace\\FileRead\\hello.txt");

Thankfully, with C++11 there is also the more pleasing approach of using raw string literals.

printf("She said \"time flies like an arrow, but fruit flies like a banana\".");

Becomes:

printf(R"(She said "time flies like an arrow, but fruit flies like a banana".)");

With respect to the addition of brackets after the opening quote, and before the closing quote, note that they can be almost any combination of up to 16 characters, helping avoid the situation where the combination is present in the string itself. Specifically:

any member of the basic source character set except: space, the left parenthesis (, the right parenthesis ), the backslash , and the control characters representing horizontal tab, vertical tab, form feed, and newline" (N3936 §2.14.5 [lex.string] grammar) and "at most 16 characters" (§2.14.5/2)

How much clearer it makes this short strings might be debatable, but when used on longer formatted strings like HTML or JSON, it's unquestionably far clearer.

If I understand well, you want to Join ScheduleRequest with User and apply the in clause to the userName property of the entity User.

I'd need to work a bit on this schema. But you can try with this trick, that is much more readable than the code you posted, and avoids the Join part (because it handles the Join logic outside the Criteria Query).

List<String> myList = new ArrayList<String> ();
for (User u : usersList) {
    myList.add(u.getUsername());
}
Expression<String> exp = scheduleRequest.get("createdBy");
Predicate predicate = exp.in(myList);
criteria.where(predicate);

In order to write more type-safe code you could also use Metamodel by replacing this line:

Expression<String> exp = scheduleRequest.get("createdBy");

with this:

Expression<String> exp = scheduleRequest.get(ScheduleRequest_.createdBy);

If it works, then you may try to add the Join logic into the Criteria Query. But right now I can't test it, so I prefer to see if somebody else wants to try.

Not a perfect answer though may be code snippets might help.

public <T> List<T> findListWhereInCondition(Class<T> clazz,
            String conditionColumnName, Serializable... conditionColumnValues) {
        QueryBuilder<T> queryBuilder = new QueryBuilder<T>(clazz);
        addWhereInClause(queryBuilder, conditionColumnName,
                conditionColumnValues);
        queryBuilder.select();
        return queryBuilder.getResultList();

    }


private <T> void addWhereInClause(QueryBuilder<T> queryBuilder,
            String conditionColumnName, Serializable... conditionColumnValues) {

        Path<Object> path = queryBuilder.root.get(conditionColumnName);
        In<Object> in = queryBuilder.criteriaBuilder.in(path);
        for (Serializable conditionColumnValue : conditionColumnValues) {
            in.value(conditionColumnValue);
        }
        queryBuilder.criteriaQuery.where(in);

    }

This code works well :

You seem to be confusing client-side and server side code. When the button is clicked you need to send (post, get) the variables to the server where the php can be executed. You can either submit the page or use an ajax call to submit just the data. -don

Take a look at this article: Mapping Object Relationships

There are two categories of object relationships that you need to be concerned with when mapping. The first category is based on multiplicity and it includes three types:

*One-to-one relationships.  This is a relationship where the maximums of each of its multiplicities is one, an example of which is holds relationship between Employee and Position in Figure 11.  An employee holds one and only one position and a position may be held by one employee (some positions go unfilled).
*One-to-many relationships. Also known as a many-to-one relationship, this occurs when the maximum of one multiplicity is one and the other is greater than one.  An example is the works in relationship between Employee and Division.  An employee works in one division and any given division has one or more employees working in it.
*Many-to-many relationships. This is a relationship where the maximum of both multiplicities is greater than one, an example of which is the assigned relationship between Employee and Task.  An employee is assigned one or more tasks and each task is assigned to zero or more employees. 

The second category is based on directionality and it contains two types, uni-directional relationships and bi-directional relationships.

*Uni-directional relationships.  A uni-directional relationship when an object knows about the object(s) it is related to but the other object(s) do not know of the original object.  An example of which is the holds relationship between Employee and Position in Figure 11, indicated by the line with an open arrowhead on it.  Employee objects know about the position that they hold, but Position objects do not know which employee holds it (there was no requirement to do so).  As you will soon see, uni-directional relationships are easier to implement than bi-directional relationships.
*Bi-directional relationships.  A bi-directional relationship exists when the objects on both end of the relationship know of each other, an example of which is the works in relationship between Employee and Division.  Employee objects know what division they work in and Division objects know what employees work in them. 

I would recommend you having a look at the basics of conditioning in bash.

The symbol "[" is a command and must have a whitespace prior to it. If you don't give whitespace after your elif, the system interprets elif[ as a a particular command which is definitely not what you'd want at this time.

Usage:

elif(A COMPULSORY WHITESPACE WITHOUT PARENTHESIS)[(A WHITE SPACE WITHOUT PARENTHESIS)conditions(A WHITESPACE WITHOUT PARENTHESIS)]

In short, edit your code segment to:

elif [ "$seconds" -gt 0 ]

You'd be fine with no compilation errors. Your final code segment should look like this:

#!/bin/sh    
if [ "$seconds" -eq 0 ];then
       $timezone_string="Z"
    elif [ "$seconds" -gt 0 ]
    then
       $timezone_string=`printf "%02d:%02d" $seconds/3600 ($seconds/60)%60`
    else
       echo "Unknown parameter"
    fi

Here is android.util.Patterns.EMAIL_ADDRESS

[a-zA-Z0-9+._\%-+]{1,256}\@[a-zA-Z0-9][a-zA-Z0-9-]{0,64}(.[a-zA-Z0-9][a-zA-Z0-9-]{0,25})+

String will match it if

Start by 1->256 character in (a-z, A-Z, 0-9, +, ., _, %, - , +)  
then 1 '@' character  
then 1 character in (a-z, A-Z, 0-9)  
then 0->64 character in (a-z, A-Z, 0-9, -)  
then **ONE OR MORE** 
         1 '.' character   
    then 1 character in (a-z, A-Z, 0-9)   
    then 0->25 character in (a-z, A-Z, 0-9, -)

Example some special match email

[email protected]
[email protected]
[email protected]

You may modify this pattern for your case then validate by

fun isValidEmail(email: String): Boolean {
    return Patterns.EMAIL_ADDRESS.matcher(email).matches()
}

Others have explained that no, you don't want this in version control. You should configure your version control system to ignore the file (e.g. via a .gitignore file).

To really understand why, it helps to see what's actually in this file. I wrote a command line tool that lets you see the .suo file's contents.

Install it on your machine via:

dotnet tool install -g suo

It has two sub-commands, keys and view.

suo keys <path-to-suo-file>

This will dump out the key for each value in the file. For example (abridged):

nuget
ProjInfoEx
BookmarkState
DebuggerWatches
HiddenSlnFolders
ObjMgrContentsV8
UnloadedProjects
ClassViewContents
OutliningStateDir
ProjExplorerState
TaskListShortcuts
XmlPackageOptions
BackgroundLoadData
DebuggerExceptions
DebuggerFindSource
DebuggerFindSymbol
ILSpy-234190A6EE66
MRU Solution Files
UnloadedProjectsEx
ApplicationInsights
DebuggerBreakpoints
OutliningStateV1674
...

As you can see, lots of IDE features use this file to store their state.

Use the view command to see a given key's value. For example:

$ suo view nuget --format=utf8 .suo
nuget

?{"WindowSettings":{"project:MyProject":{"SourceRepository":"nuget.org","ShowPreviewWindow":false,"ShowDeprecatedFrameworkWindow":true,"RemoveDependencies":false,"ForceRemove":false,"IncludePrerelease":false,"SelectedFilter":"UpdatesAvailable","DependencyBehavior":"Lowest","FileConflictAction":"PromptUser","OptionsExpanded":false,"SortPropertyName":"ProjectName","SortDirection":"Ascending"}}}

More information on the tool here: https://github.com/drewnoakes/suo

Have you considered using the "xcopy" command?

The xcopy command will do all that for you.

You're remarkably close.

Here's the code you wrote in the question:

questionText.replace(/[0-9]/g, '');

The code you've written does indeed look at the questionText variable, and produce output which is the original string, but with the digits replaced with empty string.

However, it doesn't assign it automatically back to the original variable. You need to specify what to assign it to:

questionText = questionText.replace(/[0-9]/g, '');

Try to convert one of the rows into timestamp using the pd.to_datetime function and then use .map to map the formular to the entire column

The simple approach of just averaging them has weird edge cases with angles when they wrap from 359' back to 0'.

A much earlier question on SO asked about finding the average of a set of compass angles.

An expansion of the approach recommended there for spherical coordinates would be:

• Convert each lat/long pair into a unit-length 3D vector.
• Sum each of those vectors
• Normalise the resulting vector
• Convert back to spherical coordinates

For Python 3.6+ using f-strings:

>>> i = 1
>>> f"{i:0>2}"  # Works for both numbers and strings.
'01'
>>> f"{i:02}"  # Works only for numbers.
'01'

For Python 2 to Python 3.5:

>>> "{:0>2}".format("1")  # Works for both numbers and strings.
'01'
>>> "{:02}".format(1)  # Works only for numbers.
'01'

this might be helpful:

// Operator overloading in C++
//assignment operator overloading
#include<iostream>
using namespace std;

class Employee
{
private:
int idNum;
double salary;
public:
Employee ( ) {
    idNum = 0, salary = 0.0;
}

void setValues (int a, int b);
void operator= (Employee &emp );

};

void Employee::setValues ( int idN , int sal )
{

salary = sal; idNum = idN;

}

void Employee::operator = (Employee &emp)  // Assignment operator overloading function
{
salary = emp.salary;
}

int main ( )
{

Employee emp1;
emp1.setValues(10,33);
Employee emp2;
emp2 = emp1; // emp2 is calling object using assignment operator

}

According to the docker-compose reference,

Ports is defined as:

Expose ports. Either specify both ports (HOST:CONTAINER), or just the container port (a random host port will be chosen).

• Ports mentioned in docker-compose.yml will be shared among different services started by the docker-compose.
• Ports will be exposed to the host machine to a random port or a given port.

My docker-compose.yml looks like:

mysql:
  image: mysql:5.7
  ports:
    - "3306"

If I do docker-compose ps, it will look like:

  Name                     Command               State            Ports
-------------------------------------------------------------------------------------
  mysql_1       docker-entrypoint.sh mysqld      Up      0.0.0.0:32769->3306/tcp

Expose is defined as:

Expose ports without publishing them to the host machine - they’ll only be accessible to linked services. Only the internal port can be specified.

Ports are not exposed to host machines, only exposed to other services.

mysql:
  image: mysql:5.7
  expose:
    - "3306"

If I do docker-compose ps, it will look like:

  Name                  Command             State    Ports
---------------------------------------------------------------
 mysql_1      docker-entrypoint.sh mysqld   Up      3306/tcp

Edit

In recent versions of Docker, expose doesn't have any operational impact anymore, it is just informative. (see also)

Explanation:

This problem occurs because Chrome allows up to 6 open connections by default. So if you're streaming multiple media files simultaneously from 6 <video> or <audio> tags, the 7th connection (for example, an image) will just hang, until one of the sockets opens up. Usually, an open connection will close after 5 minutes of inactivity, and that's why you're seeing your .pngs finally loading at that point.

Solution 1:

You can avoid this by minimizing the number of media tags that keep an open connection. And if you need to have more than 6, make sure that you load them last, or that they don't have attributes like preload="auto".

Solution 2:

If you're trying to use multiple sound effects for a web game, you could use the Web Audio API. Or to simplify things, just use a library like SoundJS, which is a great tool for playing a large amount of sound effects / music tracks simultaneously.

Solution 3: Force-open Sockets (Not recommended)

If you must, you can force-open the sockets in your browser (In Chrome only):

1. Go to the address bar and type chrome://net-internals.
2. Select Sockets from the menu.
3. Click on the Flush socket pools button.

This solution is not recommended because you shouldn't expect your visitors to follow these instructions to be able to view your site.

Old question but for a simple API and light-weight solution; you can use perfy which uses high-resolution real time (process.hrtime) internally.

var perfy = require('perfy');

function end(label) {
    return function (err, saved) {
        console.log(err ? 'Error' : 'Saved'); 
        console.log( perfy.end(label).time ); // <——— result: seconds.milliseconds
    };
}

for (var i = 1; i < LIMIT; i++) {
    var label = 'db-save-' + i;
    perfy.start(label); // <——— start and mark time
    db.users.save({ id: i, name: 'MongoUser [' + i + ']' }, end(label));
}

Note that each time perfy.end(label) is called, that instance is auto-destroyed.

If you already define your view in your layout(xml) file, only want to change the weight programmatically, this way is better

LinearLayout.LayoutParams params = (LinearLayout.LayoutParams)   
mButton.getLayoutParams();
params.weight = 1.0f;
mButton.setLayoutParams(params);

new a LayoutParams overwrites other params defined in you xml file like margins, or you need to specify all of them in LayoutParams.

From the man page for time:

1. There may be a shell built-in called time, avoid this by specifying /usr/bin/time

2. You can provide a format string and one of the format options is elapsed time - e.g. %E

   /usr/bin/time -f'%E' $CMD

Example:

$ /usr/bin/time -f'%E' ls /tmp/mako/
res.py  res.pyc
0:00.01

You may not want to disable all ssl Verificatication and so you can just disable the hostName verification via this which is a bit less scary than the alternative:

HttpsURLConnection.setDefaultHostnameVerifier(
    SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

[EDIT]

As mentioned by conapart3 SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER is now deprecated, so it may be removed in a later version, so you may be forced in the future to roll your own, although I would still say I would steer away from any solutions where all verification is turned off.

This suffices and stores the first line of filename in the variable $line:

read -r line < filename

I also like awk for this:

awk 'NR==1 {print; exit}' file

To store the line itself, use the var=$(command) syntax. In this case, line=$(awk 'NR==1 {print; exit}' file).

Or even sed:

sed -n '1p' file

With the equivalent line=$(sed -n '1p' file).

See a sample when we feed the read with seq 10, that is, a sequence of numbers from 1 to 10:

$ read -r line < <(seq 10) 
$ echo "$line"
1

$ line=$(awk 'NR==1 {print; exit}' <(seq 10))
$ echo "$line"
1

You can use a deadlock graph and gather the information you require from the log file.

The only other way I could suggest is digging through the information by using EXEC SP_LOCK (Soon to be deprecated), EXEC SP_WHO2 or the sys.dm_tran_locks table.

Methodology: a + b = c, so instead of looking for (a,b) we look for a = c - b

for me it was because in /etc/hosts file the hostname is not added

Simple solution:

/\s{2,}/

This matches all occurrences of one or more whitespace characters. If you need to match the entire line, but only if it contains two or more consecutive whitespace characters:

/^.*\s{2,}.*$/

If the whitespaces don't need to be consecutive:

/^(.*\s.*){2,}$/

Another short way you could use is a pipe (%<>%) from the magrittr package. It converts the character column mycolumn to a factor.

library(magrittr)

mydf$mycolumn %<>% factor

You can very easily use this to re-use the value of the variable in another function.

// Use this in source window.var1= oEvent.getSource().getBindingContext();

// Get value of var1 in destination var var2= window.var1;

This error seems to happen more commonly with a slow, or troubled internet connection. I have connected with good internet speed then it is worked perfectly.

I checked all above and it didn't work for me,

There are some steps I found.

I used PHP Version 5.5.9-1ubuntu4.17 on Ubuntu 14.04

First check the folder

#ls /etc/php5/mods-available/
json.ini  mcrypt.ini  mysqli.ini  mysql.ini  mysqlnd.ini  opcache.ini  pdo.ini  pdo_mysql.ini  readline.ini  xcache.ini

If it did not contain mysqli.ini, read other answer for installing it,

Open php.ini find extension_dir

In my case , I must set extension_dir = /usr/lib/php5/20121212

And restart apache2 : /ect/init.d/apache2 restart

For a test task, you can use the environment property like this:

test {
  environment "VAR", "val"
}

you can also use the environment property in an exec task

task dropDatabase(type: Exec) {
    environment "VAR", "val"
    commandLine "doit"
}

Note that with this method the environment variables are set only during the task.

To find out if a string contains substring you can use the index function:

if (index($str, $substr) != -1) {
    print "$str contains $substr\n";
} 

It will return the position of the first occurrence of $substr in $str, or -1 if the substring is not found.

The following would do but only will replace one occurence:

"string".replace('/', 'ForwardSlash');

For a global replacement, or if you prefer regular expressions, you just have to escape the slash:

"string".replace(/\//g, 'ForwardSlash');

Actually, for the configuration of the machine, just open the .vmx file with a text editor (e.g. notepad, gedit, etc.). You will be able to see the OS type, memsize, ethernet.connectionType, and other settings. Then when you make your machine, just look in the text editor for the corresponding settings. When it asks for the disk, select the .vmdk disk as mentioned above.

You probably looking for something like this.

FileInputStream in = new FileInputStream("inputFile.txt");
BufferedReader br = new BufferedReader(new InputStreamReader(in));

It is possible to increase heap size allocated by the JVM by using command line options Here we have 3 options

-Xms<size>        set initial Java heap size
-Xmx<size>        set maximum Java heap size
-Xss<size>        set java thread stack size

java -Xms16m -Xmx64m ClassName

In the above line we can set minimum heap to 16mb and maximum heap 64mb

One small addition to the solution posted by Pascal

When I followed this route, I got an error in maven while installing ojdbc jar.

[INFO] --- maven-install-plugin:2.5.1:install-file (default-cli) @ validator ---
[INFO] pom.xml not found in ojdbc14.jar

After adding -DpomFile, the problem was resolved.

$ mvn install:install-file -Dfile=./lib/ojdbc14.jar -DgroupId=ojdbc \
   -DartifactId=ojdbc -Dversion=14 -Dpackaging=jar -DlocalRepositoryPath=./repo \
   -DpomFile=~/.m2/repository/ojdbc/ojdbc/14/ojdbc-14.pom

If you use PHP5 (And you should, given that PHP4 has been deprecated), you should use PDO, since this is slowly becoming the new standard. One (very) important benefit of PDO, is that it supports bound parameters, which makes for much more secure code.

You would connect through PDO, like this:

try {
  $db = new PDO('mysql:dbname=databasename;host=127.0.0.1', 'username', 'password');
} catch (PDOException $ex) {
  echo 'Connection failed: ' . $ex->getMessage();
}

(Of course replace databasename, username and password above)

You can then query the database like this:

$result = $db->query("select * from tablename");
foreach ($result as $row) {
  echo $row['foo'] . "\n";
}

Or, if you have variables:

$stmt = $db->prepare("select * from tablename where id = :id");
$stmt->execute(array(':id' => 42));
$row = $stmt->fetch();

If you need multiple connections open at once, you can simply create multiple instances of PDO:

try {
  $db1 = new PDO('mysql:dbname=databas1;host=127.0.0.1', 'username', 'password');
  $db2 = new PDO('mysql:dbname=databas2;host=127.0.0.1', 'username', 'password');
} catch (PDOException $ex) {
  echo 'Connection failed: ' . $ex->getMessage();
}

To expand on what Naxos said (Thanks Naxos for sending me in the right direction!), I learned quite a bit from the recently released NDK examples and posted an answer in a similar question here.

How to configure NDK with Android Gradle plugin 0.7

This post has full details on linking prebuilt native libraries into your app for the various architectures as well as information on how to add NDK support directly to the build.gradle script. For the most part, you shouldn't need to do the work around zip and copy anymore.
