Programs & Examples On #Mqueue

For my case, Xcode 8.2.1, I had a Map Kit View in a view controller. So I went to

Build Phases > Link Binary With Libraries

and added MapKit.framework, then it was fine.

I think this will also apply to other views that require framework.

P.S. Running on iOS 9 told me that there was an issue about Map Kit View, while on iOS 10 told me nothing!

(This is already answered in comments, but since it lacks an actual answer, I'm writing this.)

This problem arises in newer versions of Visual C++ (the older versions usually just silently linked the program and it would crash and burn at run time.) It means that some of the libraries you are linking with your program (or even some of the source files inside your program itself) are using different versions of the CRT (the C RunTime library.)

To correct this error, you need to go into your Project Properties (and/or those of the libraries you are using,) then into C/C++, then Code Generation, and check the value of Runtime Library; this should be exactly the same for all the files and libraries you are linking together. (The rules are a little more relaxed for linking with DLLs, but I'm not going to go into the "why" and into more details here.)

There are currently four options for this setting:

1. Multithreaded Debug
2. Multithreaded Debug DLL
3. Multithreaded Release
4. Multithreaded Release DLL

Your particular problem seems to stem from you linking a library built with "Multithreaded Debug" (i.e. static multithreaded debug CRT) against a program that is being built using the "Multithreaded Debug DLL" setting (i.e. dynamic multithreaded debug CRT.) You should change this setting either in the library, or in your program. For now, I suggest changing this in your program.

Note that since Visual Studio projects use different sets of project settings for debug and release builds (and 32/64-bit builds) you should make sure the settings match in all of these project configurations.

For (some) more information, you can see these (linked from a comment above):

1. Linker Tools Warning LNK4098 on MSDN
2. /MD, /ML, /MT, /LD (Use Run-Time Library) on MSDN
3. Build errors with VC11 Beta - mixing MTd libs with MDd exes fail to link on Bugzilla@Mozilla

UPDATE: (This is in response to a comment that asks for the reason that this much care must be taken.)

If two pieces of code that we are linking together are themselves linking against and using the standard library, then the standard library must be the same for both of them, unless great care is taken about how our two code pieces interact and pass around data. Generally, I would say that for almost all situations just use the exact same version of the standard library runtime (regarding debug/release, threads, and obviously the version of Visual C++, among other things like iterator debugging, etc.)

The most important part of the problem is this: having the same idea about the size of objects on either side of a function call.

Consider for example that the above two pieces of code are called A and B. A is compiled against one version of the standard library, and B against another. In A's view, some random object that a standard function returns to it (e.g. a block of memory or an iterator or a FILE object or whatever) has some specific size and layout (remember that structure layout is determined and fixed at compile time in C/C++.) For any of several reasons, B's idea of the size/layout of the same objects is different (it can be because of additional debug information, natural evolution of data structures over time, etc.)

Now, if A calls the standard library and gets an object back, then passes that object to B, and B touches that object in any way, chances are that B will mess that object up (e.g. write the wrong field, or past the end of it, etc.)

The above isn't the only kind of problems that can happen. Internal global or static objects in the standard library can cause problems too. And there are more obscure classes of problems as well.

All this gets weirder in some aspects when using DLLs (dynamic runtime library) instead of libs (static runtime library.)

This situation can apply to any library used by two pieces of code that work together, but the standard library gets used by most (if not almost all) programs, and that increases the chances of clash.

What I've described is obviously a watered down and simplified version of the actual mess that awaits you if you mix library versions. I hope that it gives you an idea of why you shouldn't do it!

You can add any Git repository (or tarball) as a dependency to yarn by specifying the remote URL (either HTTPS or SSH):

yarn add <git remote url> installs a package from a remote git repository.
yarn add <git remote url>#<branch/commit/tag> installs a package from a remote git repository at specific git branch, git commit or git tag.
yarn add https://my-project.org/package.tgz installs a package from a remote gzipped tarball.

Here are some examples:

yarn add https://github.com/fancyapps/fancybox [remote url]
yarn add ssh://github.com/fancyapps/fancybox#3.0  [branch]
yarn add https://github.com/fancyapps/fancybox#5cda5b529ce3fb6c167a55d42ee5a316e921d95f [commit]

(Note: Fancybox v2.6.1 isn't available in the Git version.)

To support both npm and yarn, you can use the git+url syntax:

git+https://github.com/owner/package.git#commithashortagorbranch
git+ssh://github.com/owner/package.git#commithashortagorbranch

Try this

Check if table have there , and drop the table , then create

using (SqlCommand command = new SqlCommand("IF EXISTS (
SELECT *
FROM sys.tables
WHERE name LIKE '#Customer%')
DROP TABLE #Customer CREATE TABLE Customer(First_Name char(50),Last_Name char(50),Address char(50),City char(50),Country char(25),Birth_Date datetime);", con))

Java objects reside in an area called the heap, while metadata such as class objects and method objects reside in the permanent generation or Perm Gen area. The permanent generation is not part of the heap.

The heap is created when the JVM starts up and may increase or decrease in size while the application runs. When the heap becomes full, garbage is collected. During the garbage collection objects that are no longer used are cleared, thus making space for new objects.

-Xmssize Specifies the initial heap size.

-Xmxsize Specifies the maximum heap size.

-XX:MaxPermSize=size Sets the maximum permanent generation space size. This option was deprecated in JDK 8, and superseded by the -XX:MaxMetaspaceSize option.

Sizes are expressed in bytes. Append the letter k or K to indicate kilobytes, m or M to indicate megabytes, g or G to indicate gigabytes.

You can always read the image file as grayscale right from the beginning using imread from OpenCV:

img = cv2.imread('messi5.jpg', 0)

Furthermore, in case you want to read the image as RGB, do some processing and then convert to Gray Scale you could use cvtcolor from OpenCV:

gray_image = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)

It is not (with current browsers) possible to make an input field read-only through CSS alone.

Though, as you have already mentioned, you can apply the attribute readonly='readonly'.

If your main criteria is to not alter the markup in the source, there are ways to get this in, unobtrusively, with javascript.

With jQuery, this is easy:

 $('input').attr('readonly', true);

Or even with plain Javascript:

document.getElementById('someId').setAttribute('readonly', 'readonly');

window.location.href will give you the current url (as shown in the browser address). After parsing it and retrieving the relevant part you would compare it with each link href and assign the active class to the corresponding link.

You have a TH floating at the top of your table which isn't within a TR. Fix that.

With regards to your image problem you;re referencing the image absolutely from your computer's hard drive. Don't do that.

You also have a closing tag which shouldn't be there.

It should be:

<img src="h.gif" alt="" border="3" height="100" width="100" />

Also this:

<table border = 5 bordercolor = red align = center>

Your colspans are also messed up. You only seem to have three columns but have colspans of 14 and 4 in your code.

Should be:

<table border="5" bordercolor="red" align="center">

Also you have no DOCTYPE declared. You should at least add:

<!DOCTYPE html> 

I had a similar issue and ended up with this:

For me this has the advantage that data and annotation are not overlapping.

from matplotlib import pyplot as plt
import numpy as np

fig = plt.figure()
ax = fig.add_subplot(111)

A = -0.75, -0.25, 0, 0.25, 0.5, 0.75, 1.0
B = 0.73, 0.97, 1.0, 0.97, 0.88, 0.73, 0.54

plt.plot(A,B)

# annotations at the side (ordered by B values)
x0,x1=ax.get_xlim()
y0,y1=ax.get_ylim()
for ii, ind in enumerate(np.argsort(B)):
    x = A[ind]
    y = B[ind]
    xPos = x1 + .02 * (x1 - x0)
    yPos = y0 + ii * (y1 - y0)/(len(B) - 1)
    ax.annotate('',#label,
          xy=(x, y), xycoords='data',
          xytext=(xPos, yPos), textcoords='data',
          arrowprops=dict(
                          connectionstyle="arc3,rad=0.",
                          shrinkA=0, shrinkB=10,
                          arrowstyle= '-|>', ls= '-', linewidth=2
                          ),
          va='bottom', ha='left', zorder=19
          )
    ax.text(xPos + .01 * (x1 - x0), yPos,
            '({:.2f}, {:.2f})'.format(x,y),
            transform=ax.transData, va='center')

plt.grid()
plt.show()

Using the text argument in .annotate ended up with unfavorable text positions. Drawing lines between a legend and the data points is a mess, as the location of the legend is hard to address.

I recently had to resolve this issue and here's what I did :

First of all, this solution is around tuning Apache server.

Second main think is that there's a bug in the IE9 which means that the meta tag will not work, instead of this solution try this

• find/open your httpd.conf

• uncomment/or add the following line

  LoadModule headers_module modules/mod_headers.so
  

• add the following lines

  <IfModule headers_module>
      Header set X-UA-Compatible: IE=EmulateIE8
  </IfModule>
  

• save/restart your Apache server,

• browse to your page with IE9, use tools like wireshark or fiddler or use IE developer tools to check the header is there

Here is my solution in windows

git filter-branch --tree-filter "rm -f 'filedir/filename'" HEAD

git push --force

make sure that the path is correct otherwise it won't work

I hope it helps

You are using the correct API, but is the "marker" variable visible to the entire script. I don't see this marker variable declared globally.

Step 1: Build a checked/unchecked selector:

selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/yellow" android:state_checked="true" />
    <item android:color="@color/white" android:state_checked="false" />
</selector>

Step 2: use the xml attribute app:itemTextColor within NavigationView widget for selecting the text color.

<android.support.design.widget.NavigationView
    android:id="@+id/nav_view"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    app:headerLayout="@layout/navigation_header_layout"
    app:itemTextColor="@drawable/selector"
    app:menu="@menu/navigation_menu" />

Step 3:
For some reason when you hit an item from the NavigationView menu, it doesn't consider this as a button check. So you need to manually get the selected item checked and clear the previously selected item. Use below listener to do that

@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {

    int id = item.getItemId();

    // remove all colors of the items to the `unchecked` state of the selector
    removeColor(mNavigationView);

    // check the selected item to change its color set by the `checked` state of the selector
    item.setChecked(true);

    switch (item.getItemId()) {
      case R.id.dashboard:
          ...
    }

    drawerLayout.closeDrawer(GravityCompat.START);
    return true;
}

private void removeColor(NavigationView view) {
    for (int i = 0; i < view.getMenu().size(); i++) {
        MenuItem item = view.getMenu().getItem(i);
        item.setChecked(false);
    }
}

Step 4:
To change icon color, use the app:iconTint attribute in the NavigationView menu items, and set to the same selector.

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item
        android:id="@+id/nav_account"
        android:checked="true"
        android:icon="@drawable/ic_person_black_24dp"
        android:title="My Account"
        app:iconTint="@drawable/selector" />
    <item
        android:id="@+id/nav_settings"
        android:icon="@drawable/ic_settings_black_24dp"
        android:title="Settings"
        app:iconTint="@drawable/selector" />

    <item
        android:id="@+id/nav_logout"
        android:icon="@drawable/logout"
        android:title="Log Out"
        app:iconTint="@drawable/selector" />
</menu>

Result:

If you want to copy conditional formatting to another document you can use the "Copy to..." feature for the worksheet (click the tab with the name of the worksheet at the bottom) and copy the worksheet to the other document.

Then you can just copy what you want from that worksheet and right-click select "Paste special" -> "Paste conditional formatting only", as described earlier.

Now with new JavaScript version (ECMAScript 6 http://es6-features.org/#ClassDefinition) there is a better way to submit requests using nodejs and Promise request (http://www.wintellect.com/devcenter/nstieglitz/5-great-features-in-es6-harmony)

Using library: https://github.com/request/request-promise

npm install --save request
npm install --save request-promise

client:

//Sequential execution for node.js using ES6 ECMAScript
var rp = require('request-promise');

rp({
    method: 'POST',
    uri: 'http://localhost:3000/',
    body: {
        val1 : 1,
        val2 : 2
    },
    json: true // Automatically stringifies the body to JSON
}).then(function (parsedBody) {
        console.log(parsedBody);
        // POST succeeded...
    })
    .catch(function (err) {
        console.log(parsedBody);
        // POST failed...
    });

server:

var express = require('express')
    , bodyParser = require('body-parser');

var app = express();

app.use(bodyParser.json());

app.post('/', function(request, response){
    console.log(request.body);      // your JSON

    var jsonRequest = request.body;
    var jsonResponse = {};

    jsonResponse.result = jsonRequest.val1 + jsonRequest.val2;

    response.send(jsonResponse);
});


app.listen(3000);

A simple solution is to do this formula:

A1*7+DATE(A2,1,1)

If it returns a Wednesday, simply change the formula to:

(A1*7+DATE(A2,1,1))-2

This will only work for dates within one calendar year.

The easiest way to accomplish this is to override the RaisePostBackEvent method.

<input type="button" ID="btnRaisePostBack" runat="server" onclick="raisePostBack();" ... />

And in your JavaScript:

raisePostBack = function(){
    __doPostBack("<%=btnRaisePostBack.ClientID%>", "");
}

And in your code:

protected override void RaisePostBackEvent(IPostBackEventHandler source, string eventArgument)
{
    //call the RaisePostBack event 
    base.RaisePostBackEvent(source, eventArgument);

    if (source == btnRaisePostBack)
    {
         //do some logic
    }
}

this worked for me for c#

if (enableEndDateCheckBox.Checked == true)
{
    endDateDateTimePicker.Enabled = true;
    endDateDateTimePicker.Format = DateTimePickerFormat.Short;                
}
else
{
    endDateDateTimePicker.Enabled = false;
    endDateDateTimePicker.Format = DateTimePickerFormat.Custom;
    endDateDateTimePicker.CustomFormat = " ";
}

nice one guys!

I was also having a similar problem. Finally found one solution at https://techmeals.com/fe/questions/htmlcss/4/How-to-customize-the-select-drop-down-in-css-which-works-for-all-the-browsers

Note:

1) For Firefox support there is special CSS handling for SELECT element's parent, please take a closer look.

2) Download the down.png from Down.png

CSS code

        /* For Firefox browser we need to style for SELECT element parent. */

        @-moz-document url-prefix() {

            /* Please note this is the parent of "SELECT" element */

            .select-example {   
                background: url('https://techmeals.com/external/images/down.png');
                background-color: #FFFFFF;
                border: 1px solid #9e9e9e;
                background-size: auto 6px;
                background-repeat: no-repeat;
                background-position: 96% 13px;
            }
        }

        /* IE specific styles */
        @media all and (-ms-high-contrast: none), (-ms-high-contrast: active) 
        {
                select.my-select-box {
                padding: 0 0 0 5px;
            }
        }

        /* IE specific styles */
        @supports (-ms-accelerator:true) {
                select.my-select-box {
                padding: 0 0 0 5px;
            }
        }

        select.my-select-box  {
            outline: none;
            background: #fff;
            -moz-appearance: window;
            -webkit-appearance: none;
            border-radius: 0px;
            text-overflow: "";
            background-image: url('https://techmeals.com/external/images/down.png');
            background-size: auto 6px;
            background-repeat: no-repeat;
            background-position: 96% 13px;
            cursor: pointer;
            height: 30px;
            width: 100%;
            border: 1px solid #9e9e9e;
            padding: 0 15px 0 5px;
            padding-right: 15px\9;      /* This will be apllied only to IE 7, IE 8 and IE 9 as */
            *padding-right: 15px;        /* This will be apllied only to IE 7 and below. */
            _padding-right: 15px;       /* This will be apllied only to IE 6 and below. */
        }

HTML code

    <div class="select-example">
        <select class="my-select-box">
            <option value="1">First Option</option>
            <option value="2">Second Option</option>
            <option value="3">Third Option</option>
            <option value="4">Fourth Option</option>
        </select>

Simple code to redirect page

<!-- html button designing and calling the event in javascript -->
<input id="btntest" type="button" value="Check" 
       onclick="window.location.href = 'http://www.google.com'" />

In my instance of this problem I had to specify box-shadow: none

button:focus {
  outline:none;
  box-shadow: none;
}

I've made a jQuery plugin for the purpose of blinking notification messages in the browser title bar. You can specify different options like blinking interval, duration, if the blinking should stop when the window/tab gets focused, etc. The plugin works in Firefox, Chrome, Safari, IE6, IE7 and IE8.

Here is an example on how to use it:

$.titleAlert("New mail!", {
    requireBlur:true,
    stopOnFocus:true,
    interval:600
});

If you're not using jQuery, you might still want to look at the source code (there are a few quirky bugs and edge cases that you need to work around when doing title blinking if you want to fully support all major browsers).

Use CSS:

<html>
<head>
<style>
.Large
{
    font-size: 16pt;
    height: 50px;
}
</style>
<body>
<input type="text" class="Large">
</body>
</html>

These need to go as different commands e.g.:

NAME=sam; echo "$NAME"
NAME=sam && echo "$NAME"

The expansion $NAME to empty string is done by the shell earlier, before running echo, so at the time the NAME variable is passed to the echo command's environment, the expansion is already done (to null string).

To get the same result in one command:

NAME=sam printenv NAME

I'd solve it with a javascript solution (jQUery) if the sizes can vary.

window.setTimeout(function () {
    $(document).ready(function () {
        var ResizeTarget = $('#B');

        ResizeTarget.resize(function () {
            var target = $('#B2');
            target.css('height', ResizeTarget.height());
        }).trigger('resize');
    }); 
}, 500);

You can give tooltipTemplate a function, and format the tooltip as you wish:

tooltipTemplate: function(v) {return someFunction(v.value);}
multiTooltipTemplate: function(v) {return someOtherFunction(v.value);}

Those given 'v' arguments contain lots of information besides the 'value' property. You can put a 'debugger' inside that function and inspect those yourself.

sudo mysql

enter your (LINUX) account password

grant create on *.* to user@localhost;

FLUSH PRIVILEGES;

On a linux server you can just use this commands to reconfigure Tomcat to listen on port 80:

sed -i 's|port="8080"|port="80"|g' /etc/tomcat?/server.xml
sed -i 's|#AUTHBIND=no|AUTHBIND=yes|g' /etc/default/tomcat?
service tomcat8 restart

If you don't have any other indexes or sorted information for your objects, then you will have to iterate until such an object is found:

next(obj for obj in objs if obj.val == 5)

This is however faster than a complete list comprehension. Compare these two:

[i for i in xrange(100000) if i == 1000][0]

next(i for i in xrange(100000) if i == 1000)

The first one needs 5.75ms, the second one 58.3µs (100 times faster because the loop 100 times shorter).

Here are some more examples where _ is used:

val nums = List(1,2,3,4,5,6,7,8,9,10)

nums filter (_ % 2 == 0)

nums reduce (_ + _)

nums.exists(_ > 5)

nums.takeWhile(_ < 8)

In all above examples one underscore represents an element in the list (for reduce the first underscore represents the accumulator)

I solved the problem like this

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

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

}

This will convert the whole column:

select from_unixtime(unix_timestamp(transaction_date,'yyyyMMdd')) from table1

The problem here is very simple. If you want to display value in JSP, you have to use <%= %> tag instead of <% %>, here is the solved code:

<tr> <td><%=rs.getInt("ID") %></td> <td><%=rs.getString("NAME") %></td> <td><%=rs.getString("SKILL") %></td> </tr>

You have two ways to do this:

• Using javascript:

  <tr onclick="document.location = 'links.html';">

• Using anchors:

  <tr><td><a href="">text</a></td><td><a href="">text</a></td></tr>

I made the second work using:

table tr td a {
    display:block;
    height:100%;
    width:100%;
}

To get rid of the dead space between columns:

table tr td {
    padding-left: 0;
    padding-right: 0;
}

Here is a simple demo of the second example: DEMO

As far as I understand, the question is NOT about recursion. We can easily call main method of another class in your class. Following example illustrates static and calling by object. Note omission of word static in Class2

class Class1{
    public static void main(String[] args) {
        System.out.println("this is class 1");
    }    
}

class Class2{
    public void main(String[] args) {
        System.out.println("this is class 2");
    }    
}

class MyInvokerClass{
    public static void main(String[] args) {

        System.out.println("this is MyInvokerClass");
        Class2 myClass2 = new Class2();
        Class1.main(args);
        myClass2.main(args);
    }    
}

Output Should be:

this is wrapper class

this is class 1

this is class 2

Do this:

date('Y-m-d', strtotime('dd/mm/yyyy'));

But make sure 'dd/mm/yyyy' is the actual date.

This works perfectly as we want:

Unzip files:

find . -name "*.zip" | xargs -P 5 -I FILENAME sh -c 'unzip -o -d "$(dirname "FILENAME")" "FILENAME"'

Above command does not create duplicate directories.

Remove all zip files:

find . -depth -name '*.zip' -exec rm {} \;

My guess is that RAND_MAX is equal to INT_MAX and so you're overflowing it to a negative.

Just do this:

r = ((double) rand() / (RAND_MAX)) + 1;

Or even better, use C++11's random number generators.

Starting from Apache HTTPComponents 4.3.x HttpClientBuilder class sets the proxy defaults from System properties http.proxyHost and http.proxyPort or else you can override them using setProxy method.

There are two ways to sum of a column

dataset = pd.read_csv("data.csv")

1: sum(dataset.Column_name)

2: dataset['Column_Name'].sum()

If there is any issue in this the please correct me..

I ran into a similar issue today - my ruby version didn't match my rvm installs.

> ruby -v
ruby 2.0.0p481

> rvm list
rvm rubies
   ruby-2.1.2 [ x86_64 ]
=* ruby-2.2.1 [ x86_64 ]
   ruby-2.2.3 [ x86_64 ]

Also, rvm current failed.

> rvm current
Warning! PATH is not properly set up, '/Users/randallreed/.rvm/gems/ruby-2.2.1/bin' is not at first place...

The error message recommended this useful command, which resolved the issue for me:

> rvm get stable --auto-dotfiles

I had this problem, the solution was to look at the commit graph (using gitk) and see that I had the following:

*   commit I want to cherry-pick (x)
|\  
| * branch I want to cherry-pick to (y)
* | 
|/  
* common parent (x)

I understand now that I want to do

git cherry-pick -m 2 mycommitsha

This is because -m 1 would merge based on the common parent where as -m 2 merges based on branch y, that is the one I want to cherry-pick to.

I suspect the problem is because the json represents an object with the list of users as a property. Try deserializing to something like:

public class UsersResponse
{
    public List<User> Data { get; set; }
}

You could do it this way ..

var mystr = 'is my name.';_x000D_
mystr = mystr.replace (/^/,'John ');_x000D_
_x000D_
console.log(mystr);

Using #pragma once should work on any modern compiler, but I don't see any reason not to use a standard #ifndef include guard. It works just fine. The one caveat is that GCC didn't support #pragma once before version 3.4.

I also found that, at least on GCC, it recognizes the standard #ifndef include guard and optimizes it, so it shouldn't be much slower than #pragma once.

If your lines are multiple points instead, you can use this version.

I realize this post is a few years old, but I just wanted to extend this to anyone still struggling through this issue.

The company I work for still uses VS2015 so in turn I still use VS2015. I recently started working on a RPC application using C++ and found the need to download the Win32 Templates. Like many others I was having this "SDK 8.1 was not found" issue. i took the following corrective actions with no luck.

• I found the SDK through Micrsoft at the following link https://developer.microsoft.com/en-us/windows/downloads/sdk-archive/ as referenced above and downloaded it.
• I located my VS2015 install in Apps & Features and ran the repair.
• I completely uninstalled my VS2015 and reinstalled it.
• I attempted to manually point my console app "Executable" and "Include" directories to the C:\Program Files (x86)\Microsoft SDKs\Windows Kits\8.1 and C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1A\bin\NETFX 4.5.1 Tools.

None of the attempts above corrected the issue for me...

I then found this article on social MSDN https://social.msdn.microsoft.com/Forums/office/en-US/5287c51b-46d0-4a79-baad-ddde36af4885/visual-studio-cant-find-windows-81-sdk-when-trying-to-build-vs2015?forum=visualstudiogeneral

Finally what resolved the issue for me was:

• Uninstalling and reinstalling VS2015.
• Locating my installed "Windows Software Development Kit for Windows 8.1" and running the repair.
• Checked my "C:\Program Files (x86)\Microsoft SDKs\Windows Kits\8.1" to verify the "DesignTime" folder was in fact there.
• Opened VS created a Win32 Console application and comiled with no errors or issues

I hope this saves anyone else from almost 3 full days of frustration and loss of productivity.

I think it will help you

There are few answers here indicating both strategies for 2 different versions of Jackson library below:

For Jackson 2.6.*

ObjectMapper objMapper = new ObjectMapper(new JsonFactory()); // or YAMLFactory()
objMapper.setNamingStrategy(
     PropertyNamingStrategy.CAMEL_CASE_TO_LOWER_CASE_WITH_UNDERSCORES);

For Jackson 2.7.*

ObjectMapper objMapper = new ObjectMapper(new JsonFactory()); // or YAMLFactory()
objMapper.setNamingStrategy(
     PropertyNamingStrategy.SNAKE_CASE);

I kept running into the issue and saw that all my certs were invalidated -- oh no!

It turns out I never deleted the expired cert. It was not showing up for me, until I selected from Keychain Access application:

View->Show Expired Certificates

then

System->All Items

will finally display that gnarly expired cert. Delete that and retry from XCode will pick up the new valid certs.

Just make sure you search "All Items" in the Keychain Access app. The invalidated certs are a result of pointing to the expired certificate that has not been deleted yet.

Just use GETDATE() or GETUTCDATE() (if you want to get the "universal" UTC time, instead of your local server's time-zone related time).

INSERT INTO [Business]

           GETDATE(),  <LastUpdatedBy, nvarchar(50),>)

It seems this may have recently been added. Clicking command + control + z on the simulator will pop up a debug menu. From that menu, click Inspect. Inspect will present tabs. Click the network tab and that will show all network requests being made.

I wrote some macros that return the min and max of any type, regardless of signedness:

#define MAX_OF(type) \
    (((type)(~0LLU) > (type)((1LLU<<((sizeof(type)<<3)-1))-1LLU)) ? (long long unsigned int)(type)(~0LLU) : (long long unsigned int)(type)((1LLU<<((sizeof(type)<<3)-1))-1LLU))
#define MIN_OF(type) \
    (((type)(1LLU<<((sizeof(type)<<3)-1)) < (type)1) ? (long long int)((~0LLU)-((1LLU<<((sizeof(type)<<3)-1))-1LLU)) : 0LL)

Example code:

#include <stdio.h>
#include <sys/types.h>
#include <inttypes.h>

#define MAX_OF(type) \
    (((type)(~0LLU) > (type)((1LLU<<((sizeof(type)<<3)-1))-1LLU)) ? (long long unsigned int)(type)(~0LLU) : (long long unsigned int)(type)((1LLU<<((sizeof(type)<<3)-1))-1LLU))
#define MIN_OF(type) \
    (((type)(1LLU<<((sizeof(type)<<3)-1)) < (type)1) ? (long long int)((~0LLU)-((1LLU<<((sizeof(type)<<3)-1))-1LLU)) : 0LL)

int main(void)
{
    printf("uint32_t = %lld..%llu\n", MIN_OF(uint32_t), MAX_OF(uint32_t));

The white-space: nowrap; property dont let you wrap text. Just see here for an example: https://codepen.io/oezkany/pen/YoVgYK

if you want filename only :

for file in /home/user/*; do       
  f=$(echo "${file##*/}");
  filename=$(echo $f| cut  -d'.' -f 1); #file has extension, it return only filename
  echo $filename
done

for more information about cut command see here.

You can try this website http://www.decompileandroid.com Just upload the .apk file and rest of it will be done by this site.

By default docker containers run as the root user.

If you are still using the container you can use exit command to get back to root (default user) user instead of running the container again.

Example -

[dev@6c4c86bccf93 ~]$ ls
[dev@6c4c86bccf93 ~]$ other-commands..
[dev@6c4c86bccf93 ~]$ exit
[root@6c4c86bccf93 /]# ls

I'm running phonegap 3.1.0-0.15.0, since iOS7 changed the resolution to 120x120px I just added a file with those dimensions to the project then changed the info.plist file.

1. Add a 120x120 file to the project, by right clicking the project file in Xcode and selecting, "Add files to "[Your Project Name]"...
2. Go to the info.plist file in Xcode "Resources/[Your Project Name]-info.plist"
3. Under "Icon files (iOS 5)/Primary Icon/Icon files" change "Item 2" to whatever the filename your file had (I called mine "icon-120.png which I placed in the Project folder along side all the other icons, though this shouldn't matter)

More info can be found here: http://www.digifloor.com/missing-recommended-icon-file-error-ios-app-13

To fix the splash screen in iOS i just pasted in new files with the same dimensions and same filenames, overwriting the old ones. Just remember to go to Product>Clean in the menu bar in Xcode (shortcut Shift+Command+K) and it should work fine! :)

If you just want to know whether the certificate has expired (or will do so within the next N seconds), the -checkend <seconds> option to openssl x509 will tell you:

if openssl x509 -checkend 86400 -noout -in file.pem
then
  echo "Certificate is good for another day!"
else
  echo "Certificate has expired or will do so within 24 hours!"
  echo "(or is invalid/not found)"
fi

This saves having to do date/time comparisons yourself.

openssl will return an exit code of 0 (zero) if the certificate has not expired and will not do so for the next 86400 seconds, in the example above. If the certificate will have expired or has already done so - or some other error like an invalid/nonexistent file - the return code is 1.

(Of course, it assumes the time/date is set correctly)

Be aware that older versions of openssl have a bug which means if the time specified in checkend is too large, 0 will always be returned (https://github.com/openssl/openssl/issues/6180).

If you are going to trust a sub-domain, for example, aaa.localhost, Please don't do it like mkcert localhost *.localhost 127.0.0.1, this will not work since some browser doesn't accept wildcard subdomain.

Maybe try mkcert localhost aaa.localhost 127.0.0.1.

"dev" is not a string it is a const char * like var1. Thus you are indeed comparing the memory adresses. Being that var1 is a char pointer, *var1 is a single char (the first character of the pointed to character sequence to be precise). You can't compare a char against a char pointer, which is why that did not work.

Being that this is tagged as c++, it would be sensible to use std::string instead of char pointers, which would make == work as expected. (You would just need to do const std::string var1 instead of const char *var1.

While respond_to? will return true only for public methods, checking for "method definition" on a class may also pertain to private methods.

On Ruby v2.0+ checking both public and private sets can be achieved with

Foo.private_instance_methods.include?(:bar) || Foo.instance_methods.include?(:bar)

This can be archived by adding code on the onchange event of the select control.

For Example:

<select onchange="this.options[this.selectedIndex].value && (window.location = this.options[this.selectedIndex].value);">
    <option value="http://gmail.com">Gmail</option>
    <option value="http://youtube.com">Youtube</option>
</select>

This is the correct way of doing it http://blogs.msdn.com/b/managingsql/archive/2011/07/13/deleting-old-server-names-from-quot-connect-to-server-quot-dialog-in-ssms.aspx

I don't know if this is what you're looking for, but you can export the results to Excel like this:

In the results pane, click the top-left cell to highlight all the records, and then right-click the top-left cell and click "Save Results As". One of the export options is CSV.

You might give this a shot too:

INSERT INTO OPENROWSET 
   ('Microsoft.Jet.OLEDB.4.0', 
   'Excel 8.0;Database=c:\Test.xls;','SELECT productid, price FROM dbo.product')

Lastly, you can look into using SSIS (replaced DTS) for data exports. Here is a link to a tutorial:

http://www.accelebrate.com/sql_training/ssis_2008_tutorial.htm

== Update #1 ==

To save the result as CSV file with column headers, one can follow the steps shown below:

1. Go to Tools->Options
2. Query Results->SQL Server->Results to Grid
3. Check “Include column headers when copying or saving results”
4. Click OK.
5. Note that the new settings won’t affect any existing Query tabs — you’ll need to open new ones and/or restart SSMS.

I solved it this way:

$ brew uninstall --force node
$ brew uninstall --force npm

after it

$ brew install node

which suggested me to overwrite simlinks

Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink share/doc/node/gdbinit
Target /usr/local/share/doc/node/gdbinit
already exists. You may want to remove it:
  rm '/usr/local/share/doc/node/gdbinit'

To force the link and overwrite all conflicting files:
  brew link --overwrite node

after executing

$ brew link --overwrite node

everything worked again.

Sometimes this exception is caused by a bug in the support library implementation. Recently I had to downgrade from 26.1.0 to 25.4.0 to get rid of it.

You're looking for $(this).attr("href");

As noted above in many of the other answers, there are many good packages that connect to the XLS/X file and get the data in a reasonable way. However, you should be warned that under no circumstances should you use the clipboard (or a .csv) file to retrieve data from Excel. To see why, enter =1/3 into a cell in excel. Now, reduce the number of decimal points visible to you to two. Then copy and paste the data into R. Now save the CSV. You'll notice in both cases Excel has helpfully only kept the data that was visible to you through the interface and you've lost all of the precision in your actual source data.

Change:

 data: JSON.stringify({ model: source })

To:

 data: {model: JSON.stringify(source)}

And in your controller you do this:

public void PartSourceAPI(string model)
{
       System.Web.Script.Serialization.JavaScriptSerializer js = new System.Web.Script.Serialization.JavaScriptSerializer();

   var result = js.Deserialize<PartSourceModel>(model);
}

If the url you use in jquery is /api/PartSourceAPI then the controller name must be api and the action(method) should be PartSourceAPI

The query below demonstrates use of the package and some of the information you can get.

select sys_context ( 'USERENV', 'DB_NAME' ) db_name,
sys_context ( 'USERENV', 'SESSION_USER' ) user_name,
sys_context ( 'USERENV', 'SERVER_HOST' ) db_host,
sys_context ( 'USERENV', 'HOST' ) user_host
from dual

NOTE: The parameter ‘SERVER_HOST’ is available in 10G only.

Any Oracle User that can connect to the database can run a query against “dual”. No special permissions are required and SYS_CONTEXT provides a greater range of application-specific information than “sys.v$instance”.

This sub will populate a Collection with all files matching the filename or pattern you pass in.

Sub GetFiles(StartFolder As String, Pattern As String, _
             DoSubfolders As Boolean, ByRef colFiles As Collection)

    Dim f As String, sf As String, subF As New Collection, s
    
    If Right(StartFolder, 1) <> "\" Then StartFolder = StartFolder & "\"
    
    f = Dir(StartFolder & Pattern)
    Do While Len(f) > 0
        colFiles.Add StartFolder & f
        f = Dir()

The standard Java classloader is a stickler for directory structure. Each entry in the classpath is a directory or jar file (or zip file, really), which it then searches for the given class file. For example, if your classpath is ".;my.jar", it will search for com.example.Foo in the following locations:

./com/example/
my.jar:/com/example/

That is, it will look in the subdirectory that has the 'modified name' of the package, where '.' is replaced with the file separator.

Also, it is noteworthy that you cannot nest .jar files.

If you want use custom roles, you can do this:

CustomRoles class:

public static class CustomRoles
{
    public const string Administrator = "Administrador";
    public const string User = "Usuario";
}

Usage

[Authorize(Roles = CustomRoles.Administrator +","+ CustomRoles.User)]

If you have few roles, maybe you can combine them (for clarity) like this:

public static class CustomRoles
{
     public const string Administrator = "Administrador";
     public const string User = "Usuario";
     public const string AdministratorOrUser = Administrator + "," + User;  
}

Usage

[Authorize(Roles = CustomRoles.AdministratorOrUser)]

I've found the following "pattern" to be very useful:

MainCtrl.$inject = ['$scope', '$rootScope', '$location', 'socket', ...];
function MainCtrl (scope, rootscope, location, thesocket, ...) {

where, MainCtrl is a controller. I am uncomfortable relying on the parameter names of the Controller function doing a one-for-one mimic of the instances for fear that I might change names and muck things up. I much prefer explicitly using $inject for this purpose.

I had the same problem, and it was related to XSS (cross site scripting) block by the browser. I managed to make it work using a server.

Take a look at: http://www.daniweb.com/web-development/javascript-dhtml-ajax/threads/282972/why-am-i-getting-xmlhttprequest.status0

Albeit from the useless _T and incorrectly spelled histories. If you are using SQL*Plus, it does not accept create table statements with empty new lines between create table <name> ( and column definitions.

MVC, MVP, MVVM

MVC (old one)

MVP (more modular because of its low-coupling. Presenter is a mediator between the View and Model)

MVVM (You already have two-way binding between VM and UI component, so it is more automated than MVP)

First, you should use any WebSocket or polling mechanics to notify the frontend part about changes that happened. I use Flask-SocketIO wrapper, and very happy with async messaging for my tiny apps.

Nest, you can do all logic which you need in a separate thread(s), and notify the frontend via SocketIO object (Flask holds continuous open connection with every frontend client).

As an example, I just implemented page reload on backend file modifications:

<!doctype html>
<script>
    sio = io()

    sio.on('reload',(info)=>{
        console.log(['sio','reload',info])
        document.location.reload()
    })
</script>

class App(Web, Module):

    def __init__(self, V):
        ## flask module instance
        self.flask = flask
        ## wrapped application instance
        self.app = flask.Flask(self.value)
        self.app.config['SECRET_KEY'] = config.SECRET_KEY
        ## `flask-socketio`
        self.sio = SocketIO(self.app)
        self.watchfiles()

    ## inotify reload files after change via `sio(reload)``
    def watchfiles(self):
        from watchdog.observers import Observer
        from watchdog.events import FileSystemEventHandler
        class Handler(FileSystemEventHandler):
            def __init__(self,sio):
                super().__init__()
                self.sio = sio
            def on_modified(self, event):
                print([self.on_modified,self,event])
                self.sio.emit('reload',[event.src_path,event.event_type,event.is_directory])
        self.observer = Observer()
        self.observer.schedule(Handler(self.sio),path='static',recursive=True)
        self.observer.schedule(Handler(self.sio),path='templates',recursive=True)
        self.observer.start()

The new support v4 bring tint back to api 4.

you can do it like this

public static Drawable setTint(Drawable d, int color) {
    Drawable wrappedDrawable = DrawableCompat.wrap(d);
    DrawableCompat.setTint(wrappedDrawable, color);
    return wrappedDrawable;
}

Note that if you are trying to pass to a "figure level" method in seaborn (for example lmplot, catplot / factorplot, jointplot) you can and should specify this within the arguments using height and aspect.

sns.catplot(data=df, x='xvar', y='yvar', 
    hue='hue_bar', height=8.27, aspect=11.7/8.27)

See https://github.com/mwaskom/seaborn/issues/488 and Plotting with seaborn using the matplotlib object-oriented interface for more details on the fact that figure level methods do not obey axes specifications.

It is a special form of recursion where the last operation of a function is a recursive call. The recursion may be optimized away by executing the call in the current stack frame and returning its result rather than creating a new stack frame.

A recursive function is tail recursive when recursive call is the last thing executed by the function. For example the following C++ function print() is tail recursive.

An example of tail recursive function

    void print(int n) 
{ 
if (n < 0)  return; 
cout << " " << n; 
print(n-1);} 



// The last executed statement is recursive call 

The tail recursive functions considered better than non tail recursive functions as tail-recursion can be optimized by compiler. The idea used by compilers to optimize tail-recursive functions is simple, since the recursive call is the last statement, there is nothing left to do in the current function, so saving the current function’s stack frame is of no use.

Note for Chrome Browser released in 2020.

A future release of Chrome will only deliver cookies with cross-site requests if they are set with SameSite=None and Secure.

So if your backend server does not set SameSite=None, Chrome will use SameSite=Lax by default and will not use this cookie with { withCredentials: true } requests.

More info https://www.chromium.org/updates/same-site.

Firefox and Edge developers also want to release this feature in the future.

Spec found here: https://tools.ietf.org/html/draft-west-cookie-incrementalism-01#page-8

Adding to what deceze said above. This is a parse error, so in order to debug a parse error, create a new file in the root named debugSyntax.php. Put this in it:

<?php

///////    SYNTAX ERROR CHECK    ////////////
error_reporting(E_ALL);
ini_set('display_errors','On');

//replace "pageToTest.php" with the file path that you want to test. 
include('pageToTest.php'); 

?>

Run the debugSyntax.php page and it will display parse errors from the page that you chose to test.

It's not possible, opacity is inherited by child nodes and you can't avoid this. To have only the parent transparent, you have to play with positioning (absolute) of the elements and their z-index

All you need to do is this: click on (window) on the dropdown manue on top of your screen. click on (Editor). click on (zoom in) as many times as you need to.

Anyone who is here in 2021, can use @SteeveDroz answer; but unfortunately, that is only for 1 character. So I put it into a for loop to loop through and change each character of the string.

The Functions:

    function binary_encode($str){
        $bin = "";
        for($i = 0, $j = strlen($str); $i < $j; $i++) $bin .= decbin(ord($str[$i])) . " ";
        $bin = substr($bin, 0, strlen($bin) - 1);
        return $bin;
    }
    function binary_decode($bin){
        $char = explode(' ', $bin);
        $nstr = '';
        foreach($char as $ch) $nstr .= chr(bindec($ch));
        return $nstr;
    }

Usage:

$bin = binary_encode("String Here");
$str = binary_decode("1010011 1110100 1110010 1101001 1101110 1100111 100000 1001000 1100101 1110010 1100101");

For any person using @variable in concat_ws function to get concatenated values, don't forget to reinitialize it with empty value. Otherwise it can use old value for same session.

Set @Ids = '';

select 
  @Ids := concat_ws(',',@Ids,tbl.Id),
  tbl.Col1,
  ...
from mytable tbl;

Here is an enhancement to vc-74's post that handles commas the same way Excel does. Excel puts quotes around data if the data has a comma but doesn't quote if the data doesn't have a comma.

    public static string ToCsv(this DataTable inDataTable, bool inIncludeHeaders = true)
    {
        var builder = new StringBuilder();
        var columnNames = inDataTable.Columns.Cast<DataColumn>().Select(column => column.ColumnName);
        if (inIncludeHeaders)
            builder.AppendLine(string.Join(",", columnNames));
        foreach (DataRow row in inDataTable.Rows)
        {
            var fields = row.ItemArray.Select(field => field.ToString().WrapInQuotesIfContains(","));
            builder.AppendLine(string.Join(",", fields));
        }

        return builder.ToString();
    }

    public static string WrapInQuotesIfContains(this string inString, string inSearchString)
    {
        if (inString.Contains(inSearchString))
            return "\"" + inString+ "\"";
        return inString;
    }

Change it for

$results->fetch_array()

I faced same problem and tried all the above solution. Sadly nothing work.

1. Socket Timeout (Not worked)
2. User Agent (Not Worked)
3. SoapClient configuration, cache_wsdl and Keep-Alive etc..

This whole game of headers that we are passing. I solved my problem with adding the compression header property. This actually require when you are expecting response in gzip compressed format.

//set the Headers of Soap Client. 
$client = new SoapClient($wsdlUrl, array(
    'trace' => true, 
    'keep_alive' => true,
    'connection_timeout' => 5000,
    'cache_wsdl' => WSDL_CACHE_NONE,
    'compression'   => SOAP_COMPRESSION_ACCEPT | SOAP_COMPRESSION_GZIP | SOAP_COMPRESSION_DEFLATE,
));

Hope it helps.

Good luck.

Implicit and Explicit Waits

Implicit Wait

An implicit wait is to tell WebDriver to poll the DOM for a certain amount of time when trying to find an element or elements if they are not immediately available. The default setting is 0. Once set, the implicit wait is set for the life of the WebDriver object instance.

driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

Explicit Wait + Expected Conditions

An explicit waits is code you define to wait for a certain condition to occur before proceeding further in the code. The worst case of this is Thread.sleep(), which sets the condition to an exact time period to wait. There are some convenience methods provided that help you write code that will wait only as long as required. WebDriverWait in combination with ExpectedCondition is one way this can be accomplished.

WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement element = wait.until(
        ExpectedConditions.visibilityOfElementLocated(By.id("someid")));

I found a workaround to download latest version of ChromeDriver via WebDriverManager You could try something like,

WebDriver driver = null ;
boolean oldVersion = true;
String chromeVersion = "";
try {
    try{
        FileReader reader = new FileReader("chromeVersion.txt") ;
        BufferedReader br = new BufferedReader(reader) ;
        
        String line;
        
        while ((line = br.readLine()) != null){
            chromeVersion = line.trim();
        }
        reader.close();
    } catch (IOException e ) {}
    
    WebDriverManager.chromedriver().version(chromeVersion).setup();
    driver = new ChromeDriver() ;
} catch (Exception e) {
    oldVersion = false;
    String err = e.getMessage() ;
    chromeVersion = err.split("version is")[1].split("with binary path")[0].trim();
    try{
        FileWriter writer = new FileWriter("chromeVersion.txt", true) ;
        writer.write(chromeVersion) ;
        writer.close();
    } catch (IOException er ) {}
}

if (!oldVersion){
    WebDriverManager.chromedriver().version(chromeVersion).setup();
    driver = new ChromeDriver() ;
}

driver.get("https://www.google.com") ;

The pragmatic regex (<[^>]+) style=".*?" will solve this problem in all reasonable cases. The part of the match that is not the first captured group should be removed, like this:

$output = preg_replace('/(<[^>]+) style=".*?"/i', '$1', $input);

Match a < followed by one or more "not >" until we come to space and the style="..." part. The /i makes it work even with STYLE="...". Replace this match with $1, which is the captured group. It will leave the tag as is, if the tag doesn't include style="...".

My solution was to completely remove the block in local.xml and create it with the blocks I needed, so, for example

<customer_account>
        <reference name="left">
            <action method="unsetChild">
                <name>customer_account_navigation</name>
            </action>
            <block type="customer/account_navigation" name="customer_account_navigation" before="-" template="customer/account/navigation.phtml">
                <action method="addLink" translate="label" module="customer">
                    <name>account</name>
                    <path>customer/account/</path>
                    <label>Account Dashboard</label>
                </action>
                <action method="addLink" translate="label" module="customer">
                    <name>account_edit</name>
                    <path>customer/account/edit/</path>
                    <label>Account Information</label>
                </action>
        </block>
    </reference>
</customer_account>

You can use :

copy /b/v/y

See SS64 on COPY.

say you define the static getFactorial function inside a CodeController

then this is the way you need to call a static function, because static properties and methods exists with in the class, not in the objects created using the class.

CodeController::getFactorial($index);

----------------UPDATE----------------

To best practice I think you can put this kind of functions inside a separate file so you can maintain with more easily.

to do that

create a folder inside app directory and name it as lib (you can put a name you like).

this folder to needs to be autoload to do that add app/lib to composer.json as below. and run the composer dumpautoload command.

"autoload": {
    "classmap": [
                "app/commands",
                "app/controllers",
                ............
                "app/lib"
    ]
},

then files inside lib will autoloaded.

then create a file inside lib, i name it helperFunctions.php

inside that define the function.

if ( ! function_exists('getFactorial'))
{

    /**
     * return the factorial of a number
     *
     * @param $number
     * @return string
     */
    function getFactorial($date)
    {
        $fact = 1;

        for($i = 1; $i <= $num ;$i++)
            $fact = $fact * $i;

        return $fact;

     }
}

and call it anywhere within the app as

$fatorial_value = getFactorial(225);

Try this:

webBrowser1.DocumentText =
    "<html><body>Please enter your name:<br/>" +
    "<input type='text' name='userName'/><br/>" +
    "<a href='http://www.microsoft.com'>continue</a>" +
    "</body></html>";

ctrl+c and kill -INT <pid> are not exactly the same, to emulate ctrl+c we need to first understand the difference.

kill -INT <pid> will send the INT signal to a given process (found with its pid).

ctrl+c is mapped to the intr special character which when received by the terminal should send INT to the foreground process group of that terminal. You can emulate that by targetting the group of your given <pid>. It can be done by prepending a - before the signal in the kill command. Hence the command you want is:

kill -INT -<pid>

You can test it pretty easily with a script:

#!/usr/bin/env ruby

fork {
    trap(:INT) {
        puts 'signal received in child!'
        exit
    }
    sleep 1_000
}

puts "run `kill -INT -#{Process.pid}` in any other terminal window."
Process.wait

No magic involved, just subtract from the offset top of the element

$('html, body').animate({scrollTop: $('#contact').offset().top -100 }, 'slow');

IMHO it is considered as malformed header data.

You actually want to send those name value pairs as the request content (this is the way POST works) and not as headers.

The second way is true.

Why would you use it if you already knew the class and were going to cast it? Why not just do it the old fashioned way and make the class like you always make it? There's no advantage to this over the way it's done normally. Is there a way to take the text and operate on it thusly:

label1.txt = "Pizza" 
Magic(label1.txt) p = new Magic(lablel1.txt)(arg1, arg2, arg3);
p.method1();
p.method2();

If I already know its a Pizza there's no advantage to:

p = (Pizza)somefancyjunk("Pizza"); over
Pizza p = new Pizza();

but I see a huge advantage to the Magic method if it exists.

What is the portable way to annotate a byte[] property?

It depends on what you want. JPA can persist a non annotated byte[]. From the JPA 2.0 spec:

11.1.6 Basic Annotation

The Basic annotation is the simplest type of mapping to a database column. The Basic annotation can be applied to a persistent property or instance variable of any of the following types: Java primitive, types, wrappers of the primitive types, java.lang.String, java.math.BigInteger, java.math.BigDecimal, java.util.Date, java.util.Calendar, java.sql.Date, java.sql.Time, java.sql.Timestamp, byte[], Byte[], char[], Character[], enums, and any other type that implements Serializable. As described in Section 2.8, the use of the Basic annotation is optional for persistent fields and properties of these types. If the Basic annotation is not specified for such a field or property, the default values of the Basic annotation will apply.

And Hibernate will map a it "by default" to a SQL VARBINARY (or a SQL LONGVARBINARY depending on the Column size?) that PostgreSQL handles with a bytea.

But if you want the byte[] to be stored in a Large Object, you should use a @Lob. From the spec:

11.1.24 Lob Annotation

A Lob annotation specifies that a persistent property or field should be persisted as a large object to a database-supported large object type. Portable applications should use the Lob annotation when mapping to a database Lob type. The Lob annotation may be used in conjunction with the Basic annotation or with the ElementCollection annotation when the element collection value is of basic type. A Lob may be either a binary or character type. The Lob type is inferred from the type of the persistent field or property and, except for string and character types, defaults to Blob.

And Hibernate will map it to a SQL BLOB that PostgreSQL handles with a oid .

Is this fixed in some recent version of hibernate?

Well, the problem is that I don't know what the problem is exactly. But I can at least say that nothing has changed since 3.5.0-Beta-2 (which is where a changed has been introduced)in the 3.5.x branch.

But my understanding of issues like HHH-4876, HHH-4617 and of PostgreSQL and BLOBs (mentioned in the javadoc of the PostgreSQLDialect) is that you are supposed to set the following property

hibernate.jdbc.use_streams_for_binary=false

if you want to use oid i.e. byte[] with @Lob (which is my understanding since VARBINARY is not what you want with Oracle). Did you try this?

As an alternative, HHH-4876 suggests using the deprecated PrimitiveByteArrayBlobType to get the old behavior (pre Hibernate 3.5).

I figured out this problem by:

1. ./gradlew clean
2. Restart Android Studio

That you are running Windows. Read:

http://en.wikipedia.org/wiki/Sudo

It basically allows you to execute an application with elevated privileges. If you want to achieve a similar effect under Windows, open an administrative prompt and execute your command from there. Under Vista, this is easily done by opening the shortcut while holding Ctrl+Shift at the same time.

That being said, it might very well be possible that your account already has sufficient privileges, depending on how your OS is setup, and the Windows version used.

For the sake of future 'newbies' tackling this problem, I think a quick answer would be fitting to this thread.

Like bgporter said: Python strings are immutable, and so, in order to modify a string you have to make use of the pieces you already have.

In the following example I insert 'Fu' in to 'Kong Panda', to create 'Kong Fu Panda'

>>> line = 'Kong Panda'
>>> index = line.find('Panda')
>>> output_line = line[:index] + 'Fu ' + line[index:]
>>> output_line
'Kong Fu Panda'

In the example above, I used the index value to 'slice' the string in to 2 substrings: 1 containing the substring before the insertion index, and the other containing the rest. Then I simply add the desired string between the two and voilà, we have inserted a string inside another.

Python's slice notation has a great answer explaining the subject of string slicing.

The regular filter options in Excel don't allow for more than 2 criteria settings. To do 2+ criteria settings, you need to use the Advanced Filter option. Below are the steps I did to try this out.

http://www.bettersolutions.com/excel/EDZ483/QT419412321.htm

Set up the criteria. I put this above the values I want to filter. You could do that or put on a different worksheet. Note that putting the criteria in rows will make it an 'OR' filter and putting them in columns will make it an 'AND' filter.

1. E1 : Letters
2. E2 : =m
3. E3 : =h
4. E4 : =j

I put the data starting on row 5:

1. A5 : Letters
2. A6 :
3. A7 :
4. ...

Select the first data row (A6) and click the Advanced Filter option. The List Range should be pre-populated. Select the Criteria range as E1:E4 and click OK.

That should be it. Note that I use the '=' operator. You will want to use something a bit different to test for file extensions.

To run Java code as daemon (service) you can write JNI based stub.

http://jnicookbook.owsiak.org/recipe-no-022/

for a sample code that is based on JNI. In this case you daemonize the code that was started as Java and main loop is executed in C. But it is also possible to put main, daemon's, service loop inside Java.

https://github.com/mkowsiak/jnicookbook/tree/master/recipes/recipeNo029

Have fun with JNI!

If you have a very short list of elements you would like to handle, you could use the std::initializer_list introduced in C++11 together with auto:

#include <iostream>

int main(int, char*[])
{
    for(const auto& ext : { ".slice", ".socket", ".service", ".target" })
        std::cout << "Handling *" << ext << " systemd files" << std::endl;

    return 0;
}

Possible with HTML5.

We had the same issue and we resolved it using Spring's XML configuration as below:

Add this in your context xml file

<mvc:cors>
    <mvc:mapping path="/**"
        allowed-origins="*"
        allowed-headers="Content-Type, Access-Control-Allow-Origin, Access-Control-Allow-Headers, Authorization, X-Requested-With, requestId, Correlation-Id"
        allowed-methods="GET, PUT, POST, DELETE"/>
</mvc:cors>

start=$(date +%Y%m%d%H%M%S);
for x in {1..5};
do echo $x;
sleep 1; done;
end=$(date +%Y%m%d%H%M%S);
elapsed=$(($end-$start));
ftime=$(for((i=1;i<=$((${#end}-${#elapsed}));i++));
        do echo -n "-";
        done;
        echo ${elapsed});
echo -e "Start  : ${start}\nStop   : ${end}\nElapsed: ${ftime}"

Start  : 20171108005304
Stop   : 20171108005310
Elapsed: -------------6

In the radio button object creation code include these three lines:

  obj.check2 = false;    // add 'check2', a user-defined object property
  obj.onmouseup = function() { this.check2 = this.checked };
  obj.onclick = function() { this.checked = !this.check2 };

"." | "!" | "~" | "*" | "'" | "(" | ")" are also acceptable [RFC2396]. Really, anything can be in a GET parameter if it is properly encoded.

What about an onclick function:

    <form id="form">
    <input type="text" name="firstInput">
    <button type="button" name="namebutton" 
           onClick="$('#gif').css('visibility', 'visible');
                    $('#form').submit();">
    </form>

Of course you can put this in a function and then trigger it with an onClick

When I tested this, I tried using the position property and it worked perfectly.

HTML

<div class="main">
 <div class="body">
 //add content here
 </body>
</div>

CSS

.main{
 position: relative;
}

.body{
 position: absolute;
 height: 100%;
}

Try setting the style to display=none:

<img src="a.gif" style="display:none">

I would like to humbly add that according to this SO source: https://stackoverflow.com/a/14671362/1743693, this kind of trouble is now partially solved simply by using the following jQuery instruction:

<script> 
    $.support.cors = true;
</script>

I tried it on IE10.0.9200, and it worked immediately (using jquery-1.9.0.js).

On chrome 28.0.1500.95 - this instruction doesn't work (this happens all over as david complains in the comments at the link above)

Running chrome with --allow-file-access-from-files did not work for me (as Maistora's claims above)

I tried the options in the existing answers, mainly the one marked correct which did not work in my scenario. However, what did work was using phpMyAdmin. Select the database and then select the table, from the bottom drop down menu select "Repair table".

• Server type: MySQL
• Server version: 5.7.23 - MySQL Community Server (GPL)

For fromating output date use format. Second moment argument is for parsing - however if you omit it then you testDate will cause deprecation warning

Deprecation warning: value provided is not in a recognized RFC2822 or ISO format...

var testDate= "Fri Apr 12 2013 19:08:55 GMT-0500 (CDT)"_x000D_
_x000D_
let s= moment(testDate).format('MM/DD/YYYY');_x000D_
_x000D_
msg.innerText= s;

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.24.0/moment.min.js"></script>_x000D_
_x000D_
<div id="msg"></div>

to omit this warning you should provide parsing format

var testDate= "Fri Apr 12 2013 19:08:55 GMT-0500 (CDT)"_x000D_
_x000D_
let s= moment(testDate, 'ddd MMM D YYYY HH:mm:ss ZZ').format('MM/DD/YYYY');_x000D_
_x000D_
console.log(s);

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.24.0/moment.min.js"></script>

You are not writing your code inside any function, you can return from functions only. Remove return statement and just print the value you want.

I think this method produces very good results:

SSIS (SQL Server Integration Services) is an upgrade of DTS (Data Transformation Services), which is a feature of the previous version of SQL Server. SSIS packages can be created in BIDS (Business Intelligence Development Studio). These can be used to merge data from heterogeneous data sources into SQL Server. They can also be used to populate data warehouses, to clean and standardize data, and to automate administrative tasks.

SQL Server Integration Services (SSIS) is a component of Microsoft SQL Server 2005. It replaces Data Transformation Services, which has been a feature of SQL Server since Version 7.0. Unlike DTS, which was included in all versions, SSIS is only available in the "Standard" and "Enterprise" editions. Integration Services provides a platform to build data integration and workflow applications. The primary use for SSIS is data warehousing as the product features a fast and flexible tool for data extraction, transformation, and loading (ETL).). The tool may also be used to automate maintenance of SQL Server databases, update multidimensional cube data, and perform other functions.

one of the other tool (besides file) you can use is xdg-mime

eg xdg-mime query filetype <file>

if you have yum,

yum install xdg-utils.noarch

An example comparison of xdg-mime and file on a Subrip(subtitles) file

$ xdg-mime query filetype subtitles.srt
application/x-subrip

$ file --mime-type subtitles.srt
subtitles.srt: text/plain

in the above file only show it as plain text.

I found the problem was you can't use short URL for image "img/image.jpg"

you should use the full URL "http://www.website.com/img/image.jpg", yet I don't know why !!

I've same issue. I test this code and works well. This code Get Image from URL and put in - "bmpImage"

URL url = new URL("http://your URL");
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setReadTimeout(60000 /* milliseconds */);
            conn.setConnectTimeout(65000 /* milliseconds */);
            conn.setRequestMethod("GET");
            conn.setDoInput(true);
            conn.connect();
            int response = conn.getResponseCode();
            //Log.d(TAG, "The response is: " + response);
            is = conn.getInputStream();


            BufferedInputStream bufferedInputStream = new BufferedInputStream(is);

            Bitmap bmpImage = BitmapFactory.decodeStream(bufferedInputStream);

There are many possible options for specifying your log4j configuration. One is for the file to be named exactly "log4j.properties" and be in your classpath. Another is to name it however you want and add a System property to the command line when you start Java, like this:

-Dlog4j.configuration=file:///path/to/your/log4j.properties

All of them are outlined here http://logging.apache.org/log4j/1.2/manual.html#defaultInit

Try to add the following line in ~/.bashrc

export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH

Have you verified that there is in fact a row where Staff_Id = @PersonID? What you've posted works fine in a test script, assuming the row exists. If you comment out the insert statement, then the error is raised.

set nocount on

create table Timesheet_Hours (Staff_Id int, BookedHours int, Posted_Flag bit)

insert into Timesheet_Hours (Staff_Id, BookedHours, Posted_Flag) values (1, 5.5, 0)

set @PersonID = 1

IF EXISTS    
    (
    SELECT 1    
    FROM Timesheet_Hours    
    WHERE Posted_Flag = 1    
        AND Staff_Id = @PersonID

    BEGIN
        RAISERROR('Timesheets have already been posted!', 16, 1)
        ROLLBACK TRAN
    END

Two likely definitions:

• getActivity() in a Fragment returns the Activity the Fragment is currently associated with. (see http://developer.android.com/reference/android/app/Fragment.html#getActivity()).
• getActivity() is user-defined.

I use next code for disable options in selections

<select class="sel big" id="form_code" name="code" readonly="readonly">
   <option value="user_played_game" selected="true">1 Game</option>
   <option value="coins" disabled="">2 Object</option>
   <option value="event" disabled="">3 Object</option>
   <option value="level" disabled="">4 Object</option>
   <option value="game" disabled="">5 Object</option>
</select>

// Disable selection for options
$('select option:not(:selected)').each(function(){
 $(this).attr('disabled', 'disabled');
});

Inspired by Roger Pate:

import datetime
def todayAt (hr, min=0, sec=0, micros=0):
   now = datetime.datetime.now()
   return now.replace(hour=hr, minute=min, second=sec, microsecond=micros)    

# Usage demo1:
print todayAt (17), todayAt (17, 15)

# Usage demo2:    
timeNow = datetime.datetime.now()
if timeNow < todayAt (13):
   print "Too Early"

Here's a solution I find a little more readable -- but it will require a .forEach() shim for < IE8:

var getParams = function () {
  var params = {};
  if (location.search) {
    var parts = location.search.slice(1).split('&');

    parts.forEach(function (part) {
      var pair = part.split('=');
      pair[0] = decodeURIComponent(pair[0]);
      pair[1] = decodeURIComponent(pair[1]);
      params[pair[0]] = (pair[1] !== 'undefined') ?
        pair[1] : true;
    });
  }
  return params;
}

This is very good discussion. I had one of those moments when I wished or lets say hoped (successfully that I might add) to reinvent the wheel be it a square one. Any ways above is good discussion, so any one coming here looking for what is the difference between Element property and attribute. here is my penny worth and I did have to find it out hard way. I would keep it simple so no extraordinary tech jargon.

suppose we have a variable calls 'A'. what we are used to is as following.

Below will throw an error because simply it put its is kind of object that can only have one property and that is singular left hand side = singular right hand side object. Every thing else is ignored and tossed out in bin.

let A = 'f';
A.b =2;
console.log(A.b);

who has decided that it has to be singular = singular. People who make JavaScript and html standards and thats how engines work.

Lets change the example.

let A = {};
A.b =2;
console.log(A.b);

This time it works ..... because we have explicitly told it so and who decided we can tell it in this case but not in previous case. Again people who make JavaScript and html standards.

I hope we are on this lets complicate it further

let A = {};
A.attribute ={};
A.attribute.b=5;
console.log(A.attribute.b); // will work

console.log(A.b); // will not work

What we have done is tree of sorts level 1 then sub levels of non-singular object. Unless you know what is where and and call it so it will work else no.

This is what goes on with HTMLDOM when its parsed and painted a DOm tree is created for each and every HTML ELEMENT. Each has level of properties per say. Some are predefined and some are not. This is where ID and VALUE bits come on. Behind the scene they are mapped on 1:1 between level 1 property and sun level property aka attributes. Thus changing one changes the other. This is were object getter ans setter scheme of things plays role.

let A = {
attribute :{
id:'',
value:''
},
getAttributes: function (n) {
    return this.attribute[n];
  },
setAttributes: function (n,nn){
this.attribute[n] = nn;
if(this[n]) this[n] = nn;
},
id:'',
value:''
};



A.id = 5;
console.log(A.id);
console.log(A.getAttributes('id'));

A.setAttributes('id',7)
console.log(A.id);
console.log(A.getAttributes('id'));

A.setAttributes('ids',7)
console.log(A.ids);
console.log(A.getAttributes('ids'));

A.idsss=7;
console.log(A.idsss);
console.log(A.getAttributes('idsss'));

This is the point as shown above ELEMENTS has another set of so called property list attributes and it has its own main properties. there some predefined properties between the two and are mapped as 1:1 e.g. ID is common to every one but value is not nor is src. when the parser reaches that point it simply pulls up dictionary as to what to when such and such are present.

All elements have properties and attributes and some of the items between them are common. What is common in one is not common in another.

In old days of HTML3 and what not we worked with html first then on to JS. Now days its other way around and so has using inline onlclick become such an abomination. Things have moved forward in HTML5 where there are many property lists accessible as collection e.g. class, style. In old days color was a property now that is moved to css for handling is no longer valid attribute.

Element.attributes is sub property list with in Element property.

Unless you could change the getter and setter of Element property which is almost high unlikely as it would break hell on all functionality is usually not writable off the bat just because we defined something as A.item does not necessarily mean Js engine will also run another line of function to add it into Element.attributes.item.

I hope this gives some headway clarification as to what is what. Just for the sake of this I tried Element.prototype.setAttribute with custom function it just broke loose whole thing all together, as it overrode native bunch of functions that set attribute function was playing behind the scene.

An SSIS type of example .. (if this helps anyone)

boost::is_any_of

Strip for all characters from one string that appear in another given string:

#include <cassert>

#include <boost/range/algorithm/remove_if.hpp>
#include <boost/algorithm/string/classification.hpp>

int main() {
    std::string str = "a_bc0_d";
    str.erase(boost::remove_if(str, boost::is_any_of("_0")), str.end());
    assert((str == "abcd"));
}

Tested in Ubuntu 16.04, Boost 1.58.

Well, this is an old post but I will just contribute to the question -- someone may find it useful later:

adding 'cin.get();' function just before the return of the main() seems to always stop the program from exiting before printing the results: see sample code below:

int main(){ string fname, lname;

  //ask user to enter name first and last name
  cout << "Please enter your first name: ";
  cin >> fname;

  cout << "Please enter your last name: ";
  cin >> lname;     
  cout << "\n\n\n\nyour first name is: " << fname << "\nyour last name is: " 
  << lname <<endl;

  //stop program from exiting before printing results on the screen
  cin.get();
  return 0;

}

As others have pointed out, using the * operator for a mutable object duplicates references, so if you change one you change them all. If you want to create independent instances of a mutable object, your xrange syntax is the most Pythonic way to do this. If you are bothered by having a named variable that is never used, you can use the anonymous underscore variable.

[e for _ in xrange(n)]

$datediff = floor(strtotime($date1)/(60*60*24)) - floor(strtotime($date2)/(60*60*24));

and, if needed:

$datediff=abs($datediff);

This works:

$a = array(1 => 1, 2 => 2, 3 => 3);
$b = array(4 => 4, 5 => 5, 6 => 6);
$c = $a + $b;
print_r($c);

An emulator is a model of a system which will accept any valid input that that the emulated system would accept, and produce the same output or result. So your software is an emulator, only if it reproduces the behavior of the emulated system precisely.

Similar to what StuartLC was saying, my problem was not resolved until I enabled TCP/IP protocol under SQL Network Configuration>>Protocols for MSSQLSERVER in the SQL Server Configuration Manager dialogue box. After enabling this and a restart, my SSMS connected right away with just the instance name (no ~\MSSQLSERVER).

To iterate over all the key-value pairs in a table you can use pairs:

for k, v in pairs(arr) do
  print(k, v[1], v[2], v[3])
end

outputs:

pears   2   p   green
apples  0   a   red
oranges 1   o   orange

Edit: Note that Lua doesn't guarantee any iteration order for the associative part of the table. If you want to access the items in a specific order, retrieve the keys from arr and sort it. Then access arr through the sorted keys:

local ordered_keys = {}

for k in pairs(arr) do
    table.insert(ordered_keys, k)
end

table.sort(ordered_keys)
for i = 1, #ordered_keys do
    local k, v = ordered_keys[i], arr[ ordered_keys[i] ]
    print(k, v[1], v[2], v[3])
end

outputs:

  apples  a   red     5
  oranges o   orange  12
  pears   p   green   7

        <alpha android:fromAlpha="1.0" android:toAlpha="0.0"
            android:duration="@android:integer/config_mediumAnimTime" />
    </set>

2) create sliding_in_left.xml in anim folder

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate android:fromXDelta="50%p" android:toXDelta="0"
        android:duration="@android:integer/config_mediumAnimTime"/>
    <alpha android:fromAlpha="0.0" android:toAlpha="1.0"
        android:duration="@android:integer/config_mediumAnimTime" />
</set>

3) simply using fragment transaction setCustomeAnimations() with two custom xml and two default xml for animation as follows :-

 fragmentTransaction.setCustomAnimations(R.anim.sliding_in_left, R.anim.sliding_out_right, android.R.anim.slide_in_left, android.R.anim.slide_out_right );

(You're not searching through "JSON", you're searching through an array -- the JSON string has already been deserialized into an object graph, in this case an array.)

Some options:

Use an Object Instead of an Array

If you're in control of the generation of this thing, does it have to be an array? Because if not, there's a much simpler way.

Say this is your original data:

[
    {"id": "one",   "pId": "foo1", "cId": "bar1"},
    {"id": "two",   "pId": "foo2", "cId": "bar2"},
    {"id": "three", "pId": "foo3", "cId": "bar3"}
]

Could you do the following instead?

{
    "one":   {"pId": "foo1", "cId": "bar1"},
    "two":   {"pId": "foo2", "cId": "bar2"},
    "three": {"pId": "foo3", "cId": "bar3"}
}

Then finding the relevant entry by ID is trivial:

id = "one"; // Or whatever
var entry = objJsonResp[id];

...as is updating it:

objJsonResp[id] = /* New value */;

...and removing it:

delete objJsonResp[id];

This takes advantage of the fact that in JavaScript, you can index into an object using a property name as a string -- and that string can be a literal, or it can come from a variable as with id above.

Putting in an ID-to-Index Map

(Dumb idea, predates the above. Kept for historical reasons.)

It looks like you need this to be an array, in which case there isn't really a better way than searching through the array unless you want to put a map on it, which you could do if you have control of the generation of the object. E.g., say you have this originally:

[
    {"id": "one",   "pId": "foo1", "cId": "bar1"},
    {"id": "two",   "pId": "foo2", "cId": "bar2"},
    {"id": "three", "pId": "foo3", "cId": "bar3"}
]

The generating code could provide an id-to-index map:

{
    "index": {
        "one": 0, "two": 1, "three": 2
    },
    "data": [
        {"id": "one",   "pId": "foo1", "cId": "bar1"},
        {"id": "two",   "pId": "foo2", "cId": "bar2"},
        {"id": "three", "pId": "foo3", "cId": "bar3"}
    ]
}

Then getting an entry for the id in the variable id is trivial:

var index = objJsonResp.index[id];
var obj = objJsonResp.data[index];

This takes advantage of the fact you can index into objects using property names.

Of course, if you do that, you have to update the map when you modify the array, which could become a maintenance problem.

But if you're not in control of the generation of the object, or updating the map of ids-to-indexes is too much code and/ora maintenance issue, then you'll have to do a brute force search.

Brute Force Search (corrected)

Somewhat OT (although you did ask if there was a better way :-) ), but your code for looping through an array is incorrect. Details here, but you can't use for..in to loop through array indexes (or rather, if you do, you have to take special pains to do so); for..in loops through the properties of an object, not the indexes of an array. Your best bet with a non-sparse array (and yours is non-sparse) is a standard old-fashioned loop:

var k;
for (k = 0; k < someArray.length; ++k) { /* ... */ }

or

var k;
for (k = someArray.length - 1; k >= 0; --k) { /* ... */ }

Whichever you prefer (the latter is not always faster in all implementations, which is counter-intuitive to me, but there we are). (With a sparse array, you might use for..in but again taking special pains to avoid pitfalls; more in the article linked above.)

Using for..in on an array seems to work in simple cases because arrays have properties for each of their indexes, and their only other default properties (length and their methods) are marked as non-enumerable. But it breaks as soon as you set (or a framework sets) any other properties on the array object (which is perfectly valid; arrays are just objects with a bit of special handling around the length property).

document.getElementById('Id').value='new value';

This describes something like,

InvocationTargetException is a checked exception that wraps an exception thrown by an invoked method or constructor. As of release 1.4, this exception has been retrofitted to conform to the general purpose exception-chaining mechanism. The "target exception" that is provided at construction time and accessed via the getTargetException() method is now known as the cause, and may be accessed via the Throwable.getCause() method, as well as the aforementioned "legacy method."

@Bean
    public WebMvcConfigurer corsConfigurer() {
        return new WebMvcConfigurer() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/**").allowedOrigins("*").allowedMethods("*");
            }
        };
    }

this is a bit of my code that stores and retrieves to local storage. i use broadcast events to save and restore the values in the model.

app.factory('userService', ['$rootScope', function ($rootScope) {

    var service = {

        model: {
            name: '',
            email: ''
        },

        SaveState: function () {
            sessionStorage.userService = angular.toJson(service.model);
        },

        RestoreState: function () {
            service.model = angular.fromJson(sessionStorage.userService);
        }
    }

    $rootScope.$on("savestate", service.SaveState);
    $rootScope.$on("restorestate", service.RestoreState);

    return service;
}]);

for email validation, <input type="email"> is enough..

for mobile no use pattern attribute for input as follows:

<input type="number" pattern="\d{3}[\-]\d{3}[\-]\d{4}" required>

you can check for more patterns on http://html5pattern.com.

for focusing on field, you can use onkeyup() event as:

function check()
{

    var mobile = document.getElementById('mobile');
   
    
    var message = document.getElementById('message');

   var goodColor = "#0C6";
    var badColor = "#FF9B37";
  
    if(mobile.value.length!=10){
       
        mobile.style.backgroundColor = badColor;
        message.style.color = badColor;
        message.innerHTML = "required 10 digits, match requested format!"
    }}

and your HTML code should be:

<input name="mobile"  id="mobile" type="number" required onkeyup="check(); return false;" ><span id="message"></span>

I use Remote login with vnc-ltsp-config with GNOME Desktop Environment on CentOS 5.9. From experimenting today, I managed to get cut and paste working for the session and the login prompt (because I'm lazy and would rather copy and paste difficult passwords).

1. I created a file vncconfig.desktop in the /etc/xdg/autostart directory which enabled cut and paste during the session after login. The vncconfig process is run as the logged in user.

   [Desktop Entry]
   Name=No name
   Encoding=UTF-8
   Version=1.0
   Exec=vncconfig -nowin
   X-GNOME-Autostart-enabled=true
   

2. Added vncconfig -nowin & to the bottom of the file /etc/gdm/Init/Desktop which enabled cut and paste in the session during login but terminates after login. The vncconfig process is run as root.

3. Adding vncconfig -nowin & to the bottom of the file /etc/gdm/PostLogin/Desktop also enabled cut and paste during the session after login. The vncconfig process is run as root however.

import 'core-js/es7/array' 

into polyfill.ts worked for me.

Changing the owner on "system-global" folders is a hack. On a fresh install, I would configure NPM to use an already writable location for "user-global" programs:

npm config set prefix ~/npm

Then make sure you add that folder to your path:

export PATH="$PATH:$HOME/npm/bin"

See @ErikAndreas' answer to NPM modules won't install globally without sudo and longer step-by-step guide by @sindresorhus with also sets $MANPATH.

<create-report-card-form [currentReportCardCount]="providerData.reportCards.length" ...
                         ^^^^^^^^^^^^^^^^^^^^^^^^

In your HomeComponent template, you are trying to bind to an input on the CreateReportCardForm component that doesn't exist.

In CreateReportCardForm, these are your only three inputs:

@Input() public reportCardDataSourcesItems: SelectItem[];
@Input() public reportCardYearItems: SelectItem[];
@Input() errorMessages: Message[];

Add one for currentReportCardCount and you should be good to go.

There are a couple of ways to solve this problem

Pyinx - a pretty lightweight tool that allows you to call Python from withing the excel process space http://code.google.com/p/pyinex/

I've used this one a few years ago (back when it was being actively developed) and it worked quite well

If you don't mind paying, this looks pretty good

https://datanitro.com/product.html

I've never used it though

Though if you are already writting in Python, maybe you could drop excel entirely and do everything in pure python? It's a lot easier to maintain one code base (python) rather than 2 (python + whatever excel overlay you have).

If you really have to output your data into excel there are even some pretty good tools for that in Python. If that may work better let me know and I'll get the links.

Because this post is the top one found on stackoverflow when searching for "ORA-00942: table or view does not exist insert", I want to mention another possible cause of this error (at least in Oracle 12c): a table uses a sequence to set a default value and the user executing the insert query does not have select privilege on the sequence. This was my problem and it took me an unnecessarily long time to figure it out.

To reproduce the problem, execute the following SQL as user1:

create sequence seq_customer_id;

create table customer (
c_id number(10) default seq_customer_id.nextval primary key,
name varchar(100) not null,
surname varchar(100) not null
);

grant select, insert, update, delete on customer to user2;

Then, execute this insert statement as user2:

insert into user1.customer (name,surname) values ('michael','jackson');

The result will be "ORA-00942: table or view does not exist" even though user2 does have insert and select privileges on user1.customer table and is correctly prefixing the table with the schema owner name. To avoid the problem, you must grant select privilege on the sequence:

grant select on seq_customer_id to user2;

Actually, Only this these commands are needed:

VBoxManage clonehd "source.vmdk" "cloned.vdi" --format vdi
VBoxManage modifyhd "cloned.vdi" --resize 51200

Then, you can select cloned.dvi in Virtualbox GUI storage.

After that, start the virtual windows and expand your C disk as the methods of Code Chops.

It is not necessary to convert the *.vdi file to *.vmdk file back.

In addition to Delan Azabani's answer, I like to share my console.js, and I use for the same purpose. I create a noop console using an array of function names, what is in my opinion a very convenient way to do this, and I took care of Internet Explorer, which has a console.log function, but no console.debug:

// Create a noop console object if the browser doesn't provide one...
if (!window.console){
  window.console = {};
}

// Internet Explorer has a console that has a 'log' function, but no 'debug'. To make console.debug work in Internet Explorer,
// We just map the function (extend for info, etc. if needed)
else {
  if (!window.console.debug && typeof window.console.log !== 'undefined') {
    window.console.debug = window.console.log;
  }
}

// ... and create all functions we expect the console to have (taken from Firebug).
var names = ["log", "debug", "info", "warn", "error", "assert", "dir", "dirxml",
    "group", "groupEnd", "time", "timeEnd", "count", "trace", "profile", "profileEnd"];

for (var i = 0; i < names.length; ++i){
  if(!window.console[names[i]]){
    window.console[names[i]] = function() {};
  }
}

Try using SELECT INTO....

SELECT ....
INTO     TABLE_NAME(table you want to create)
FROM source_table

C#

string upTwoDir = Path.GetFullPath(Path.Combine(System.AppContext.BaseDirectory, @"..\..\"));

If the jre is installed on your machine properly then look for keytool in jre or in jre/bin

1. to find where jre is installed, use this

   sudo find / -name jre

2. Then look for keytool in path_to_jre or in path_to_jre/bin

3. cd to keytool location

4. then run ./keytool

5. Make sure to add the the path to $PATH by

   export PATH=$PATH:location_to_keytool

6. To make sure you got it right after this, run

   where keytool

7. for future edit you bash or zshrc file and source it

Yes there is a static nested class in java. When you declare a nested class static, it automatically becomes a stand alone class which can be instantiated without having to instantiate the outer class it belongs to.

Example:

public class A
{

 public static class B
 {
 }
}

Because class B is declared static you can explicitly instantiate as:

B b = new B();

Note if class B wasn't declared static to make it stand alone, an instance object call would've looked like this:

A a= new A();
B b = a.new B();

One could achieve something similar in react native with position: absolute

let footerStyle = {
  position: 'absolute',
  bottom: 0,
}

There are a few things to keep in mind though.

1. absolute positions the element relative to its parent.
2. You might have to set the width and hight of the element manually.
3. Width and hight will change when orientation changes. This has to be managed manually

A practical style definition would look something like this:

import { Dimensions } from 'react-native';

var screenWidth = Dimensions.get('window').width; //full screen width

let footerStyle = {
  position: 'absolute',
  bottom: 0,
  width: screenWidth,
  height: 60
}

There are multiple hardware revisions of Nexus 5. So, the accepted answer doesn't work for all devices (it didn't work for me).

1. Open Device Manager, right click and Properties. Now go to the "Details" tab And now select the property "Hardware Ids". Note down the PID and VID.

2. Download the Google driver

3. Update the android_winusb.inf with above VID and PID

   %CompositeAdbInterface% = USB_Install, USB\VID_18D1&**PID_4EE1**
   

4. Now in Device Manager, find Nexus 5, and update the driver software, and browse to the location where you downloaded.

5. The driver should be installed, and you should be see the device in ADB.

To specify both font size and rotation at the same time, try this:

plt.xticks(fontsize=14, rotation=90)

Mutable objects have fields that can be changed, immutable objects have no fields that can be changed after the object is created.

A very simple immutable object is a object without any field. (For example a simple Comparator Implementation).

class Mutable{
  private int value;

  public Mutable(int value) {
     this.value = value;
  }

  //getter and setter for value
}

class Immutable {
  private final int value;

  public Immutable(int value) {
     this.value = value;
  }

  //only getter
}

UDP: Anything where you don't care too much if you get all data always

• Tunneling/VPN (lost packets are ok - the tunneled protocol takes care of it)
• Media streaming (lost frames are ok)
• Games that don't care if you get every update
• Local broadcast mechanisms (same application running on different machines "discovering" each other)

TCP: Almost anything where you have to get all transmitted data

• Web
• SSH, FTP, telnet
• SMTP, sending mail
• IMAP/POP, receiving mail

EDIT: I'm not going to bother explaining the differences, since you state that you already know and every other answer explains it anyway :)

>>> lst = [1, 2, 3]
>>> print('\n'.join('{}: {}'.format(*k) for k in enumerate(lst)))
0: 1
1: 2
2: 3

Note: you just need to understand that list comprehension or iterating over a generator expression is explicit looping.

Since I haven't seen an answer that deal with numerical and non-numerical attributes, here is a complement answer.

You might want to drop the outliers only on numerical attributes (categorical variables can hardly be outliers).

Function definition

I have extended @tanemaki's suggestion to handle data when non-numeric attributes are also present:

from scipy import stats

def drop_numerical_outliers(df, z_thresh=3):
    # Constrains will contain `True` or `False` depending on if it is a value below the threshold.
    constrains = df.select_dtypes(include=[np.number]) \
        .apply(lambda x: np.abs(stats.zscore(x)) < z_thresh, reduce=False) \
        .all(axis=1)
    # Drop (inplace) values set to be rejected
    df.drop(df.index[~constrains], inplace=True)

Usage

drop_numerical_outliers(df)

Example

Imagine a dataset df with some values about houses: alley, land contour, sale price, ... E.g: Data Documentation

First, you want to visualise the data on a scatter graph (with z-score Thresh=3):

# Plot data before dropping those greater than z-score 3. 
# The scatterAreaVsPrice function's definition has been removed for readability's sake.
scatterAreaVsPrice(df)

# Drop the outliers on every attributes
drop_numerical_outliers(train_df)

# Plot the result. All outliers were dropped. Note that the red points are not
# the same outliers from the first plot, but the new computed outliers based on the new data-frame.
scatterAreaVsPrice(train_df)

I extended @Pratik Sharmas code to use BigDecimal objects instead of ints so that it can accept larger numbers, and account for any formatting in the EditText that isn't a number (like currency formatting i.e. spaces, commas and periods)

EDIT: note that this implementation has 2 as the minimum significant figures set on the BigDecimal (see the MIN_SIG_FIG constant) as I used it for currency, so there was always 2 leading numbers before the decimal point. Alter the MIN_SIG_FIG constant as necessary for your own implementation.

public class InputFilterMinMax implements InputFilter {
private static final int MIN_SIG_FIG = 2;
private BigDecimal min, max;

public InputFilterMinMax(BigDecimal min, BigDecimal max) {
    this.min = min;
    this.max = max;
}

public InputFilterMinMax(String min, String max) {
    this.min = new BigDecimal(min);
    this.max = new BigDecimal(max);
}

@Override
public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart,
        int dend) {
    try {
        BigDecimal input = formatStringToBigDecimal(dest.toString()
                + source.toString());

        if (isInRange(min, max, input)) {

            return null;
        }
    } catch (NumberFormatException nfe) {

    }
    return "";
}

private boolean isInRange(BigDecimal a, BigDecimal b, BigDecimal c) {
    return b.compareTo(a) > 0 ? c.compareTo(a) >= 0 && c.compareTo(b) <= 0
            : c.compareTo(b) >= 0 && c.compareTo(a) <= 0;
}

public static BigDecimal formatStringToBigDecimal(String n) {

    Number number = null;
    try {
        number = getDefaultNumberFormat().parse(n.replaceAll("[^\\d]", ""));

        BigDecimal parsed = new BigDecimal(number.doubleValue()).divide(new BigDecimal(100), 2,
                BigDecimal.ROUND_UNNECESSARY);
        return parsed;
    } catch (ParseException e) {
        return new BigDecimal(0);
    }
}

private static NumberFormat getDefaultNumberFormat() {
    NumberFormat nf = NumberFormat.getInstance(Locale.getDefault());
    nf.setMinimumFractionDigits(MIN_SIG_FIG);
    return nf;
}

Very short answer :

Different databases have different uses. I'm not a database expert. Rule of thumb:

• if you are doing analytics (ex. aggregating historical data) use OLAP
• if you are doing transactions (ex. adding/removing orders on an e-commerce cart) use OLTP

Short answer:

Let's consider two example scenarios:

Scenario 1:

You are building an online store/website, and you want to be able to:

• store user data, passwords, previous transactions...
• store actual products, their associated prices

You want to be able to find data for a particular user, change its name... basically perform INSERT, UPDATE, DELETE operations on user data. Same with products, etc.

You want to be able to make transactions, possibly involving a user buying a product (that's a relation). Then OLTP is probably a good fit.

Scenario 2:

You have an online store/website, and you want to compute things like

• the "total money spent by all users"
• "what is the most sold product"

This falls into the analytics/business intelligence domain, and therefore OLAP is probably more suited.

If you think in terms of "It would be nice to know how/what/how much"..., and that involves all "objects" of one or more kind (ex. all the users and most of the products to know the total spent) then OLAP is probably better suited.

Longer answer:

Of course things are not so simple. That's why we have to use short tags like OLTPand OLAP in the first place. Each database should be evaluated independently in the end.

So what could be the fundamental difference between OLAP and OLTP?

Well, databases have to store data somewhere. It shouldn't be surprising that the way the data is stored heavily reflects the possible use of said data. Data is usually stored on a hard drive. Let's think of a hard drive as a really wide sheet of paper, where we can read and write things. There are two ways to organize our reads and writes so that they can be efficient and fast.

One way is to make a book that is a bit like a phone book. On each page of the book, we store the information regarding a particular user. Now that's nice, we can find the information for a particular user very easily! Just jump to the page! We can even have a special page at the beginning to tell us on which page the users are if we want. But on the other hand, if we want to find, say, how much money all of our users spent then we would have to read every page, i.e. the whole book! That would be a row-based book/database (OLTP). The optional page at the beginning would be the index.

Another way to use our big sheet of paper is to make an accounting book. I'm no accountant, but let's imagine that we would have a page for "expenditures", "purchases"... That's nice because now we can query things like "give me the total revenue" very quickly (just read the "purchases" page). We can also ask for more involved things like "give me the top ten products sold" and still have acceptable performance. But now consider how painful it would be to find the expenditures for a particular user. You would have to go through the whole list of everyone's expenditures and filter the ones of that particular user, then sum them. Which basically amounts to "read the whole book" again. That would be a column-based database (OLAP).

It follows that:

• OLTP databases are meant to be used to do many small transactions, and usually serve as a "single source of truth".

• OLAP databases on the other hand are more suited for analytics, data mining, fewer queries but they are usually bigger (they operate on more data).

It's a bit more involved than that of course and that's a 20 000 feet overview of how databases differ, but it allows me not to get lost in a sea of acronyms.

Speaking of acronyms:

• OLTP = Online transaction processing
• OLAP = Online analytical processing

To read a bit further, here are some relevant links which heavily inspired my answer:

• http://datawarehouse4u.info/OLTP-vs-OLAP.html
• http://www.ibmsystemsmag.com/Blogs/You-and-i/Archive/db-102-database-orientation-row-vs-column/
• http://martinfowler.com/bliki/DataLake.html

call generateNumbers(numbers);, your generateNumbers(); expects int[] as an argument ans you were passing none, thus the error

If I understand your problem correctly, you are calling a method instead of passing it as a parameter. Try the following:

myTimer.Elapsed += PlayMusicEvent;

where

public void PlayMusicEvent(object sender, ElapsedEventArgs e)
{
    music.player.Stop();
    System.Timers.Timer myTimer = (System.Timers.Timer)sender;
    myTimer.Stop();
}

But you need to think about where to store your note.

In very laymen terms the class is a mold and the object is the copy made with that mold. Static belong to the mold and can be accessed directly without making any copies, hence the example above

You have to use br when using echo , like this :

echo "Thanks for your email" ."<br>". "Your orders details are below:"

and it will work properly

Bind to the change event instead of click. However, you will probably still need to check whether or not the checkbox is checked:

$(".checkbox").change(function() {
    if(this.checked) {
        //Do stuff
    }
});

The main benefit of binding to the change event over the click event is that not all clicks on a checkbox will cause it to change state. If you only want to capture events that cause the checkbox to change state, you want the aptly-named change event. Redacted in comments

Also note that I've used this.checked instead of wrapping the element in a jQuery object and using jQuery methods, simply because it's shorter and faster to access the property of the DOM element directly.

Edit (see comments)

To get all checkboxes you have a couple of options. You can use the :checkbox pseudo-selector:

$(":checkbox")

Or you could use an attribute equals selector:

$("input[type='checkbox']")

Just call it using super.

public void myMethod()
{
    // B stuff
    super.myMethod();
    // B stuff
}

To avoid refresh of page, if the return false is not working with asp:LinkButton use

href="javascript: void;"

or

href="#"

along with OnClientClick="return false;"

<asp:LinkButton ID="linkPrint" runat="server" CausesValidation="False" href="javascript: void;"
        OnClientClick="javascript:self.print();return false;">Print</asp:LinkButton>

Above is code will call the browser print without refresh the page.

I know this is old, but I ran into the same issue. I'm on a Mac/Ubuntu and switch back and forth. What I have found is that just sending a simple interrupt signal to the main R process does exactly what you're looking for. I've ran scripts that went on for as long as 24 hours and the signal interrupt works very well. You should be able to run kill in terminal:

$ kill -2 pid

You can find the pid by running

$ps aux | grep exec/R

Not sure about Windows since I'm not ever on there, but I can't imagine there's not an option to do this as well in Command Prompt/Task Manager

Hope this helps!

var jsonData = { Name: "Ricardo Vasquez", age: "46", Email: "[email protected]" };

for (x in jsonData) {   
  console.log(x +" => "+ jsonData[x]);  
  alert(x +" => "+  jsonData[x]);  
  }

This is how session state works in ASP.NET and ASP.NET MVC:

ASP.NET Session State Overview

Basically, you do this to store a value in the Session object:

Session["FirstName"] = FirstNameTextBox.Text;

To retrieve the value:

var firstName = Session["FirstName"];

Using the previous method with more than 1 slide at time was giving me the wrong total so I've used the "dotsClass", like this (on v1.7.1):

// JS

var slidesPerPage = 6

$(".slick").on("init", function(event, slick){
   maxPages = Math.ceil(slick.slideCount/slidesPerPage);
   $(this).find('.slider-paging-number li').append('/ '+maxPages);
});

$(".slick").slick({
   slidesToShow: slidesPerPage,
   slidesToScroll: slidesPerPage,
   arrows: false,
   autoplay: true,
   dots: true,
   infinite: true,
   dotsClass: 'slider-paging-number'
});

// CSS

ul.slider-paging-number {
    list-style: none;
    li {
        display: none;
        &.slick-active {
            display: inline-block;
        }
        button {
            background: none;
            border: none;
        }
    }
}

I had following Problem: Even if I set

xdebug.remote_enable=0 

Xdebug-Error-Message-Decoration was shown.

My solution:

xdebug.default_enable=0

Only if I use this Flag, Xdebug was disabled.

simple synchronous way with node:

let fs = require('fs')

let filename = "your-file.something"

let content = fs.readFileSync(process.cwd() + "/" + filename).toString()

console.log(content)

Simple generic extensions

public static class Extensions
{

    /// <summary>
    /// Generic method for format nullable values
    /// </summary>
    /// <returns>Formated value or defaultValue</returns>
    public static string ToString<T>(this Nullable<T> nullable, string format, string defaultValue = null) where T : struct
    {
        if (nullable.HasValue)
        {
            return String.Format("{0:" + format + "}", nullable.Value);
        }

        return defaultValue;
    }
}

If including a library is overkill here is a solution that is guaranteed to work.

$('div').click(function() {
    $(this).css('background-color','#FFFFCC');
    setTimeout(function() { $(this).fadeOut('slow').fadeIn('slow'); } , 1000); 
    setTimeout(function() { $(this).css('background-color','#FFFFFF'); } , 1000); 
});

1. Setup event trigger

2. Set the background color of block element

3. Inside setTimeout use fadeOut and fadeIn to create a little animation effect.

4. Inside second setTimeout reset default background color

   Tested in a few browsers and it works nicely.

An important difference is that some UARTs (16550 notably) will stop receiving characters immediately if their host instructs them to set DSR to be inactive. In contrast, characters will still be received if CTS is inactive. I believe that the intention here is that DSR indicates that the device is no longer listening and so sending any further characters is pointless, while CTS indicates that a buffer is getting full; the latter allows for a certain amount of 'skid' where the flow control line changed state between the DTE sampling it and the next character being transmitted. In (relatively) later devices that support a hardware FIFO it's possible that a number of characters could be transmitted after the DCE has set CTS to be inactive.

Quick fix:

To remove the gap under the image, you can:

• Set the vertical-align property of the image to vertical-align: bottom; vertical-align: top; or vertical-align: middle;
• Set the display property of the image to display:block;

See the following code for a live demo:

#vAlign img {_x000D_
  vertical-align :bottom;_x000D_
}_x000D_
#block img{_x000D_
  display:block;_x000D_
}_x000D_
_x000D_
div {border: 1px solid red;width:100px;}_x000D_
img {width:100px;}

<p>No fix:</p>_x000D_
<div><img src="http://i.imgur.com/RECDV24.jpg" /></div>_x000D_
_x000D_
<p>With vertical-align:bottom; on image:</p>_x000D_
<div id="vAlign"><img src="http://i.imgur.com/RECDV24.jpg" /></div>_x000D_
_x000D_
<p>With display:block; on image:</p>_x000D_
<div id="block"><img src="http://i.imgur.com/RECDV24.jpg" /></div>

Explanation: why is there a gap under the image?

The gap or extra space under the image isn't a bug or issue, it is the default behaviour. The root cause is that images are replaced elements (see MDN replaced elements). This allows them to "act like image" and have their own intrinsic dimensions, aspect ratio....
Browsers compute their display property to inline but they give them a special behaviour which makes them closer to inline-block elements (as you can vertical align them, give them a height, top/bottom margin and padding, transforms ...).

This also means that:

<img> has no baseline, so when images are used in an inline formatting context with vertical-align: baseline, the bottom of the image will be placed on the text baseline.
(source: MDN, emphasis mine)

As browsers by default compute the vertical-align property to baseline, this is the default behaviour. The following image shows where the baseline is located on text:

(Image source)

Baseline aligned elements need to keep space for the descenders that extend below the baseline (like j, p, g ...) as you can see in the above image. In this configuration, the bottom of the image is aligned on the baseline as you can see in this example:

div{border:1px solid red;font-size:30px;}_x000D_
img{width:100px;height:auto;}

<div>_x000D_
  <img src="http://i.imgur.com/RECDV24.jpg" />jpq are letters with descender_x000D_
</div>

This is why the default behaviour of the <img> tag creates a gap at the bottom of it's container and why changing the vertical-align property or the display property removes it as in the following demo:

div {width: 100px;border: 1px solid red;}_x000D_
img {width: 100px;height: auto;}_x000D_
_x000D_
.block img{_x000D_
  display:block;_x000D_
}_x000D_
.bottom img{_x000D_
  vertical-align:bottom;_x000D_
}

<p>Default:</p>_x000D_
<div>_x000D_
  <img src="http://i.imgur.com/RECDV24.jpg" />_x000D_
</div>_x000D_
<p>With display:block;</p>_x000D_
<div class="block">_x000D_
  <img src="http://i.imgur.com/RECDV24.jpg" />_x000D_
</div>_x000D_
<p>With vertical-align:bottom;</p>_x000D_
<div class="bottom">_x000D_
  <img src="http://i.imgur.com/RECDV24.jpg" />_x000D_
</div>

That's a case where you should use if clauses.

The Thread class is used for creating and manipulating a thread in Windows.

A Task represents some asynchronous operation and is part of the Task Parallel Library, a set of APIs for running tasks asynchronously and in parallel.

In the days of old (i.e. before TPL) it used to be that using the Thread class was one of the standard ways to run code in the background or in parallel (a better alternative was often to use a ThreadPool), however this was cumbersome and had several disadvantages, not least of which was the performance overhead of creating a whole new thread to perform a task in the background.

Nowadays using tasks and the TPL is a far better solution 90% of the time as it provides abstractions which allows far more efficient use of system resources. I imagine there are a few scenarios where you want explicit control over the thread on which you are running your code, however generally speaking if you want to run something asynchronously your first port of call should be the TPL.

When you use laravel modules, you may add the name's module:

@include('cimple::shared.posts_list')

var ItemSchema = new Schema({
    name : { type: String }
});

ItemSchema.set('timestamps', true); // this will add createdAt and updatedAt timestamps
