That's a known issue. Currently you have to use a workaround like shown in your question.

This is working as intended. When the change event is emitted ngModelChange (the (...) part of [(ngModel)] hasn't updated the bound model yet:

<input type="checkbox"  (ngModelChange)="myModel=$event" [ngModel]="mymodel">

Although NVARCHAR stores Unicode, you should consider by the help of collation also you can use VARCHAR and save your data of your local languages.

Just imagine the following scenario.

The collation of your DB is Persian and you save a value like '???' (Persian writing of Ali) in the VARCHAR(10) datatype. There is no problem and the DBMS only uses three bytes to store it.

However, if you want to transfer your data to another database and see the correct result your destination database must have the same collation as the target which is Persian in this example.

If your target collation is different, you see some question marks(?) in the target database.

Finally, remember if you are using a huge database which is for usage of your local language, I would recommend to use location instead of using too many spaces.

I believe the design can be different. It depends on the environment you work on.

I think @Aredridel's post was closest, but there's a bit more to that - so I will add this here; the thing is, in svn, if you're in a subfolder of a repo, and you do:

/media/disk/repo_svn/subdir$ svn export . /media/disk2/repo_svn_B/subdir

then svn will export all files that are under revision control (they could have also freshly Added; or Modified status) - and if you have other "junk" in that directory (and I'm not counting .svn subfolders here, but visible stuff like .o files), it will not be exported; only those files registered by the SVN repo will be exported. For me, one nice thing is that this export also includes files with local changes that have not been committed yet; and another nice thing is that the timestamps of the exported files are the same as the original ones. Or, as svn help export puts it:

2. Exports a clean directory tree from the working copy specified by PATH1, at revision REV if it is given, otherwise at WORKING, into PATH2. ... If REV is not specified, all local changes will be preserved. Files not under version control will not be copied.

To realize that git will not preserve the timestamps, compare the output of these commands (in a subfolder of a git repo of your choice):

/media/disk/git_svn/subdir$ ls -la .

... and:

/media/disk/git_svn/subdir$ git archive --format=tar --prefix=junk/ HEAD | (tar -t -v --full-time -f -)

... and I, in any case, notice that git archive causes all the timestamps of the archived file to be the same! git help archive says:

git archive behaves differently when given a tree ID versus when given a commit ID or tag ID. In the first case the current time is used as the modification time of each file in the archive. In the latter case the commit time as recorded in the referenced commit object is used instead.

... but apparently both cases set the "modification time of each file"; thereby not preserving the actual timestamps of those files!

So, in order to also preserve the timestamps, here is a bash script, which is actually a "one-liner", albeit somewhat complicated - so below it is posted in multiple lines:

/media/disk/git_svn/subdir$ git archive --format=tar master | (tar tf -) | (\
  DEST="/media/diskC/tmp/subdirB"; \
  CWD="$PWD"; \
  while read line; do \
    DN=$(dirname "$line"); BN=$(basename "$line"); \
    SRD="$CWD"; TGD="$DEST"; \
    if [ "$DN" != "." ]; then \
      SRD="$SRD/$DN" ; TGD="$TGD/$DN" ; \
      if [ ! -d "$TGD" ] ; then \
        CMD="mkdir \"$TGD\"; touch -r \"$SRD\" \"$TGD\""; \
        echo "$CMD"; \
        eval "$CMD"; \
      fi; \
    fi; \
    CMD="cp -a \"$SRD/$BN\" \"$TGD/\""; \
    echo "$CMD"; \
    eval "$CMD"; \
    done \
)

Note that it is assumed that you're exporting the contents in "current" directory (above, /media/disk/git_svn/subdir) - and the destination you're exporting into is somewhat inconveniently placed, but it is in DEST environment variable. Note that with this script; you must create the DEST directory manually yourself, before running the above script.

After the script is ran, you should be able to compare:

ls -la /media/disk/git_svn/subdir
ls -la /media/diskC/tmp/subdirB   # DEST

... and hopefully see the same timestamps (for those files that were under version control).

Hope this helps someone,
Cheers!

After t.thielemans' answer, I worked that just

=VLOOKUP(A1, B:C, 2, FALSE) 

works fine and does what I wanted, except that it returns #N/A for non-matches; so it is suitable for the case where it is known that the value definitely exists in the look-up column.

Edit (based on t.thielemans' comment):

To avoid #N/A for non-matches, do:

=IFERROR(VLOOKUP(A1, B:C, 2, FALSE), "No Match")

var defaultsettings = {
    ajaxsettings: {
        ...
    },
    uisettings: {
        ...
    }
};

To change transparency on an svg code the simplest way is to open it on any text editor and look for the style attributes. It depends on the svg creator the way the styles are displayed. As i am an Inkscape user the usual way it set the style values is through a style tag just as if it were html but using svg native attributes like fill, stroke, stroke-width, opacity and so on. opacity affects the whole svg object, or path or group in which its stated and fill-opacity, stroke-opacity will affect just the fill and the stroke transparency. That said, I have also used and tasted to just use fill and instead of using#fff use instead the rgba standard like this rgba(255, 255, 255, 1) just as in css. This works fine for must modern browsers.

Keep in mind that if you intend to further reedit your svg the best practice, in my experience, is to always keep an untouched version at hand. Inkscape is more flexible with hand changed svgs but Illustrator and CorelDraw may have issues importing and edited svg.

Notice that in the last example the fill-opacity has been removed as rgba standard covers both color and alpha channel.

I would rewrite your dequeue function as:

std::string FileQueue::dequeue(const std::chrono::milliseconds& timeout)
{
    std::unique_lock<std::mutex> lock(qMutex);
    while(q.empty()) {
        if (populatedNotifier.wait_for(lock, timeout) == std::cv_status::timeout ) 
           return std::string();
    }
    std::string ret = q.front();
    q.pop();
    return ret;
}

It is shorter and does not have duplicate code like your did. Only issue it may wait longer that timeout. To prevent that you would need to remember start time before loop, check for timeout and adjust wait time accordingly. Or specify absolute time on wait condition.

Promise emits a single value while Observable emits multiple values. So, while handling a HTTP request, Promise can manage a single response for the same request, but what if there are multiple responses to the same request, then we have to use Observable. Yes, Observable can handle multiple responses for the same request.

Promise

const promise = new Promise((data) =>
{ data(1);
  data(2);
  data(3); })
.then(element => console.log(‘Promise ‘ + element));

Output

Promise 1

Observable

const observable = new Observable((data) => {
data.next(1);
data.next(2);
data.next(3);
}).subscribe(element => console.log('Observable ' + element));

Output

Observable 1
Observable 2

Every time you get this kind of error

Convert the integer into a string and then you can use the STUFF function to insert in your colons into time string. Once you've done that you can convert the string into a time datatype.

SELECT CAST(STUFF(STUFF(STUFF(cast(23421155 as varchar),3,0,':'),6,0,':'),9,0,'.') AS TIME)

That should be the simplest way to convert it to a time without doing anything to crazy.

In your example you also had an int where the leading zeros are not there. In that case you can simple do something like this:

SELECT CAST(STUFF(STUFF(STUFF(RIGHT('00000000' + CAST(421151 AS VARCHAR),8),3,0,':'),6,0,':'),9,0,'.') AS TIME)

Given the fact that you can switch to origin/master (though in detached state) while having your network cable unplugged, it must be a local representation of the master branch at origin.

I took Mr. Fooz's code and also added Arlen's solution too and here are the timings that I've gotten for Octave:

clc; clear all;
V = rand(1024*1024*32,1);
N = 10;
tic; for i=1:N, V1 = V/norm(V);         end; toc % 7.0 s
tic; for i=1:N, V2 = V/sqrt(sum(V.*V)); end; toc % 6.4 s
tic; for i=1:N, V3 = V/sqrt(V'*V);      end; toc % 5.5 s
tic; for i=1:N, V4 = V/sqrt(sum(V.^2)); end; toc % 6.6 s
tic; for i=1:N, V1 = V/norm(V);         end; toc % 7.1 s
tic; for i=1:N, d = 1/norm(V); V1 = V*d;end; toc % 4.7 s

Then, because of something I'm currently looking at, I tested out this code for ensuring that each row sums to 1:

clc; clear all;
m = 2048;
V = rand(m);
N = 100;
tic; for i=1:N, V1 = V ./ (sum(V,2)*ones(1,m));                end; toc % 8.2 s
tic; for i=1:N, V2 = bsxfun(@rdivide, V, sum(V,2));            end; toc % 5.8 s
tic; for i=1:N, V3 = bsxfun(@rdivide, V, V*ones(m,1));         end; toc % 5.7 s
tic; for i=1:N, V4 = V ./ (V*ones(m,m));                       end; toc % 77.5 s
tic; for i=1:N, d = 1./sum(V,2);V5 = bsxfun(@times, V, d);     end; toc % 2.83 s
tic; for i=1:N, d = 1./(V*ones(m,1));V6 = bsxfun(@times, V, d);end; toc % 2.75 s
tic; for i=1:N, V1 = V ./ (sum(V,2)*ones(1,m));                end; toc % 8.2 s

Had the same problem, tried the solution above but though it worked generally, for some reason I was getting permission denial on Uri content provider for some images although I had the android.permission.MANAGE_DOCUMENTS permission added properly.

Anyway found other solution which is to force opening image gallery instead of KITKAT documents view with :

// KITKAT

i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    startActivityForResult(i, CHOOSE_IMAGE_REQUEST);

and then load the image:

Uri selectedImageURI = data.getData();
input = c.getContentResolver().openInputStream(selectedImageURI);
                BitmapFactory.decodeStream(input , null, opts);

EDIT

ACTION_OPEN_DOCUMENT might require you to persist permissions flags etc and generally often results in Security Exceptions...

Other solution is to use the ACTION_GET_CONTENT combined with c.getContentResolver().openInputStream(selectedImageURI) which will work both on pre-KK and KK. Kitkat will use new documents view then and this solution will work with all apps like Photos, Gallery, File Explorer, Dropbox, Google Drive etc...) but remember that when using this solution you have to create image in your onActivityResult() and store it on SD Card for example. Recreating this image from saved uri on next app launch would throw Security Exception on content resolver even when you add permission flags as described in Google API docs (that's what happened when I did some testing)

Additionally the Android Developer API Guidelines suggest:

ACTION_OPEN_DOCUMENT is not intended to be a replacement for ACTION_GET_CONTENT. The one you should use depends on the needs of your app:

Use ACTION_GET_CONTENT if you want your app to simply read/import data. With this approach, the app imports a copy of the data, such as an image file.

Use ACTION_OPEN_DOCUMENT if you want your app to have long term, persistent access to documents owned by a document provider. An example would be a photo-editing app that lets users edit images stored in a document provider.

Just a generic note. a way to keep it flexible.

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

I wrote this method:

    private string GetUrlParameter(HttpRequestBase request, string parName)
    {
        string result = string.Empty;

        var urlParameters = HttpUtility.ParseQueryString(request.Url.Query);
        if (urlParameters.AllKeys.Contains(parName))
        {
            result = urlParameters.Get(parName);
        }

        return result;
    }

And I call it like this:

string fooBar = GetUrlParameter(Request, "FooBar");
if (!string.IsNullOrEmpty(fooBar))
{

}

Try the outline property W3Schools - CSS Outline

Outline will not interfere with widths and lenghts of the elements/divs!

Please click the link I provided at the bottom to see working demos of the the different ways you can make borders, and inner/inline borders, even ones that do not disrupt the dimensions of the element! No need to add extra divs every time, as mentioned in another answer!

You can also combine borders with outlines, and if you like, box-shadows (also shown via link)

<head>
   <style type="text/css" ref="stylesheet">
      div {
        width:22px;
        height:22px;
        outline:1px solid black;
      }
   </style>
</head>
<div>
    outlined
</div>

Usually by default, 'border:' puts the border on the outside of the width, measurement, adding to the overall dimensions, unless you use the 'inset' value:

div {border: inset solid 1px black};

But 'outline:' is an extra border outside of the border, and of course still adds extra width/length to the element.

Hope this helps

PS: I also was inspired to make this for you : Using borders, outlines, and box-shadows

I just found the same issue with Aliases on a Windows install of Xampp.

To solve the 403 error:

<Directory "C:/Your/Directory/With/No/Trailing/Slash">
   Require all granted
</Directory>

Alias /dev "C:/Your/Directory/With/No/Trailing/Slash"

The default Xampp set up should be fine with just this. Some people have experienced issues with a deny placed on the root directory so flipping out the directory tag to:

<Directory "C:/Your/Directory/With/No/Trailing/Slash">
   Allow from all
   Require all granted
</Directory>

Would help with this but the current version of Xampp (v1.8.1 at the time of writing) doesn't require it.

As for op's issue with port 80 Xampp includes a handy Netstat button to discover what's using your ports. Fire that off and fix the conflict, I imagine it could have been IIS but can't be sure.

This code is for the headset profiles, probably it will work for other profiles too. First you need to provide profile listener (Kotlin code):

private val mProfileListener = object : BluetoothProfile.ServiceListener {
    override fun onServiceConnected(profile: Int, proxy: BluetoothProfile) {
        if (profile == BluetoothProfile.HEADSET) 
            mBluetoothHeadset = proxy as BluetoothHeadset            
    }

    override fun onServiceDisconnected(profile: Int) {
        if (profile == BluetoothProfile.HEADSET) {
            mBluetoothHeadset = null
        }
    }
}

Then while checking bluetooth:

mBluetoothAdapter.getProfileProxy(context, mProfileListener, BluetoothProfile.HEADSET)
if (!mBluetoothAdapter.isEnabled) {
    return Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE)
}

It takes a bit of time until onSeviceConnected is called. After that you may get the list of the connected headset devices from:

mBluetoothHeadset!!.connectedDevices

This works:

     function showhide(id) {_x000D_
        var e = document.getElementById(id);_x000D_
        e.style.display = (e.style.display == 'block') ? 'none' : 'block';_x000D_
     }

    <!DOCTYPE html>_x000D_
    <html>   _x000D_
    <body>_x000D_
    _x000D_
     <a href="javascript:showhide('uniquename')">_x000D_
      Click to show/hide._x000D_
     </a>_x000D_
    _x000D_
     <div id="uniquename" style="display:none;">_x000D_
      <p>Content goes here.</p>_x000D_
     </div>_x000D_
    _x000D_
    </body>_x000D_
    </html>

You can use querySelectorAll to get all span elements and then use new ES2015 (ES6) spread operator convert StaticNodeList that querySelectorAll returns to array of spans, and then use map operator to get list of items.

See example bellow

([...document.querySelectorAll('#test span')]).map(x => console.log(x.innerHTML))

<div id="test">_x000D_
    <span>1</span>_x000D_
    <span>2</span>_x000D_
    <span>3</span>_x000D_
    <span>4</span>_x000D_
<div>

This code is same as posted from one of above answers.. but will convert transparent pixel to white instead of black ... Thanks:)

        if (sourceWidth < sourceHeight)
        {
            int buff = newWidth;

            new Rectangle(sourceX, sourceY, sourceWidth, sourceHeight),

        grPhoto.Dispose();
        imgPhoto.Dispose();

        return bmPhoto;
    }

The issue here is that your JSP is talking directly to the response OutputStream. This technically isn't forbidden, but it's very much not a good idea.

Specifically, you call response.getOutputStream() and write data to that. Later, when the JSP engine tries to flush the response, it fails because your code has already "claimed" the response. An application can either call getOutputStream or getWriter on any given response, it's not allowed to do both. JSP engines use getWriter, and so you cannot call getOutputStream.

You should be writing this code as a Servlet, not a JSP. JSPs are only really suitable for textual output as contained in the JSP. You can see that there's no actual text output in your JSP, it only contains java.

In Oracle database we can achieve like this.

CREATE TABLE Student(
  StudentID Number(38, 0) not null,
  DepartmentID Number(38, 0) not null,
  PRIMARY KEY (StudentID, DepartmentID)
);

I had using solution all this way in this thread, and it's easy working with plugin Android Drawable Importer

If u using Android Studio on MacOS, just try this step to get in:

• Click bar menu Android Studio then choose Preferences or tap button Command + ,
• Then choose Plugins
• Click Browse repositories
• Write in the search coloumn Android Drawable Importer
• Click Install button
• And then dialog Restart is showing, just restart it Android Studio

After ur success installing the plugin, to work it this plugin just click create New menu and then choose Batch Drawable Import. Then click plus button a.k.a Add button, and go choose your file to make drawable. And then just click ok and ok the drawable has make it all of them.

If u confused with my word, just see the image tutorial from learningmechine.

For swift 4 and you can adjust imageView size

 let logoContainer = UIView(frame: CGRect(x: 0, y: 0, width: 270, height: 30))

 let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 270, height: 30))
 imageView.contentMode = .scaleAspectFit
 let image = UIImage(named: "your_image")
 imageView.image = image
 logoContainer.addSubview(imageView)
 navigationItem.titleView = logoContainer

I would recommend this to anyone looking for missing functionality:

http://code.google.com/p/ddr-ecma5/

It brings in most of the missing ecma5 functionality to older browers :)

Here is a more complete example:

import csv
import numpy as np

with open('filename','rb') as csvfile:
     cdl = list( csv.reader(csvfile,delimiter='\t'))
     print "Number of records = " + str(len(cdl))

#then later

npcdl = np.array(cdl)

Hope this helps!!

In my experience, the best way is right:0;, left:0; and margin:0 auto. This way if the div is wide then you aren't hindered by the left: 50%; that will offset your div which results in adding negative margins etc.

DEMO http://jsfiddle.net/kevinPHPkevin/DeTJH/4/

#logo {
    background:red;
    height:50px;
    position:absolute;
    width:50px;
    margin:0 auto;
    right:0;
    left:0;
}

when using (i.e.) getConstructor(String.lang) the constructor has to be declared public. Otherwise a NoSuchMethodException is thrown.

if you want to access a non-public constructor you have to use instead (i.e.) getDeclaredConstructor(String.lang).

Use jQuery

Look how easy it would be if you did.

Example:

$('#td1').html('hello world');

There's no easy answer, because Object — which every object in JavaScript derives from — includes many attributes automatically, and the exact set of attributes you get depends on the particular interpreter and what code has executed before yours. So, you somehow have to separate the ones you defined from those you got "for free."

Here's one way:

var foo = {"key1": "value1", "key2": "value2", "key3": "value3"};
Object.prototype.foobie = 'bletch'; // add property to foo that won't be counted

var count = 0;
for (var k in foo) {
    if (foo.hasOwnProperty(k)) {
       ++count;
    }
}
alert("Found " + count + " properties specific to foo");

The second line shows how other code can add properties to all Object derivatives. If you remove the hasOwnProperty() check inside the loop, the property count will go up to at least 4. On a page with other JavaScript besides this code, it could be higher than 4, if that other code also modifies the Object prototype.

try this.

if (ViewState["CurrentTable"] != null)
            {
                DataTable dtCurrentTable = (DataTable)ViewState["CurrentTable"];
                DataRow drCurrentRow = null;
                if (dtCurrentTable.Rows.Count > 0)
                {
                    for (int i = 1; i <= dtCurrentTable.Rows.Count; i++)
                    {
                        //extract the TextBox values
                        TextBox box1 = (TextBox)Gridview1.Rows[i].Cells[1].FindControl("txt_type");
                        TextBox box2 = (TextBox)Gridview1.Rows[i].Cells[2].FindControl("txt_total");
                        TextBox box3 = (TextBox)Gridview1.Rows[i].Cells[3].FindControl("txt_max");
                        TextBox box4 = (TextBox)Gridview1.Rows[i].Cells[4].FindControl("txt_min");
                        TextBox box5 = (TextBox)Gridview1.Rows[i].Cells[5].FindControl("txt_rate");

                        drCurrentRow = dtCurrentTable.NewRow();
                        drCurrentRow["RowNumber"] = i + 1;

                        dtCurrentTable.Rows[i - 1]["Column1"] = box1.Text;
                        dtCurrentTable.Rows[i - 1]["Column2"] = box2.Text;
                        dtCurrentTable.Rows[i - 1]["Column3"] = box3.Text;
                        dtCurrentTable.Rows[i - 1]["Column4"] = box4.Text;
                        dtCurrentTable.Rows[i - 1]["Column5"] = box5.Text;

                        rowIndex++;
                    }
                    dtCurrentTable.Rows.Add(drCurrentRow);
                    ViewState["CurrentTable"] = dtCurrentTable;

                    Gridview1.DataSource = dtCurrentTable;
                    Gridview1.DataBind();
                }
            }
            else
            {
                Response.Write("ViewState is null");
            }

This is how I have fixed it:

Steps:

1. Declared a global namespace, for e.g. custom.d.ts as below :

declare global {
    namespace NodeJS {
        interface Global {
            Config: {}
        }
    }
}
export default global;

2. Map the above created a file into "tsconfig.json" as below:

"typeRoots": ["src/types/custom.d.ts" ]

3. Get the above created global variable in any of the files as below:

console.log(global.config)

Note:

1. typescript version: "3.0.1".

2. In my case, the requirement was to set the global variable before boots up the application and the variable should access throughout the dependent objects so that we can get the required config properties.

Hope this helps!

Thank you

UPDATE databaseName.tableName
SET columnName = replace(columnName, '?', '''')

Reference: See DecodeConfig section on the official go lang image lib docs here

I believe you could also use DecodeConfig to get the format of an image which you could then validate against const types like jpeg, png, jpg and gif ie

import (
  "encoding/base64"
  "fmt"
  "image"
  "log"
  "strings"
  "net/http"

  // Package image/jpeg is not used explicitly in the code below,
  // but is imported for its initialization side-effect, which allows
  // image.Decode to understand JPEG formatted images. Uncomment these
  // two lines to also understand GIF and PNG images:
  // _ "image/gif"
  // _ "image/png"
  _ "image/jpeg"
   )

func main() {
  resp, err := http.Get("http://i.imgur.com/Peq1U1u.jpg")
  if err != nil {
      log.Fatal(err)
  }
  defer resp.Body.Close()
  data, _, err := image.Decode(resp.Body)
  if err != nil {
      log.Fatal(err)
  }
  reader := base64.NewDecoder(base64.StdEncoding, strings.NewReader(data))
  config, format, err := image.DecodeConfig(reader)
  if err != nil {
      log.Fatal(err)
  }
  fmt.Println("Width:", config.Width, "Height:", config.Height, "Format:", format)
}

format here is a string that states the file format eg jpg, png etc

Try This

<button class="click_on_enterkey" type="button" onclick="return false;">
<script>
$('.click_on_enterkey').on('keyup',function(event){
  if(event.keyCode == 13){
    $(this).click();
  }
});
<script>

Interpreting newlines as <br /> used to be a feature of Github-flavored markdown, but the most recent help document no longer lists this feature.

Fortunately, you can do it manually. The easiest way is to ensure that each line ends with two spaces. So, change

a
b
c

into

a__
b__
c

(where _ is a blank space).

Or, you can add explicit <br /> tags.

a <br />
b <br />
c

This is my solution for example for an div data-attributes:

<?

$attributes = array(
    'data-href'   => 'http://example.com',
    'data-width'  => '300',
    'data-height' => '250',
    'data-type'   => 'cover',
);

$dataAttributes = array_map(function($value, $key) {
    return $key.'="'.$value.'"';
}, array_values($attributes), array_keys($attributes));

$dataAttributes = implode(' ', $dataAttributes);

?>

<div class="image-box" <?= $dataAttributes; ?> >
    <img src="http://example.com/images/best-of.jpg" alt="">
</div>

To put what others have said in a pithier manner...

Exceptions are for Exceptional circumstances

If this method is pure data access layer, I would say that given some parameter that gets included in a select statement, it would expect that I may not find any rows from which to build an object, and therefore returning null would be acceptable as this is data access logic.

On the other hand, if I expected my parameter to reflect a primary key and I should only get one row back, if I got more than one back I would throw an exception. 0 is ok to return null, 2 is not.

Now, if I had some login code that checked against an LDAP provider then checked against a DB to get more details and I expected those should be in sync at all times, I might toss the exception then. As others said, it's business rules.

Now I'll say that is a general rule. There are times where you may want to break that. However, my experience and experiments with C# (lots of that) and Java(a bit of that) has taught me that it is much more expensive performance wise to deal with exceptions than to handle predictable issues via conditional logic. I'm talking to the tune of 2 or 3 orders of magnitude more expensive in some cases. So, if it's possible your code could end up in a loop, then I would advise returning null and testing for it.

Set the seed using srand(). Also, you're not specifying the max value in rand(), so it's using RAND_MAX. I'm not sure if it's actually 10000... why not just specify it. Although, we don't know what your "expected results" are. It's a random number generator. What are you expecting, and what are you seeing?

As noted in another comment, SA() isn't returning anything explicitly.

http://pubs.opengroup.org/onlinepubs/009695399/functions/rand.html http://www.thinkage.ca/english/gcos/expl/c/lib/rand.html

Edit: From Generating random number between [-1, 1] in C? ((float)rand())/RAND_MAX returns a floating-point number in [0,1]

This code only checks if the number is divisible by two. For a number to be prime, it must not be evenly divisible by all integers less than itself. This can be naively implemented by checking if it is divisible by all integers less than floor(sqrt(n)) in a loop. If you are interested, there are a number of much faster algorithms in existence.

Fully working implementation, including escaping of Unicode and ASCII non printable characters. Does not insert "+" signs like Hallgrim's answer.

    static string ToLiteral(string input) {
        StringBuilder literal = new StringBuilder(input.Length + 2);
        literal.Append("\"");
        foreach (var c in input) {
            switch (c) {
                case '\'': literal.Append(@"\'"); break;
                case '\"': literal.Append("\\\""); break;
                case '\\': literal.Append(@"\\"); break;
                case '\0': literal.Append(@"\0"); break;
                case '\a': literal.Append(@"\a"); break;
                case '\b': literal.Append(@"\b"); break;
                case '\f': literal.Append(@"\f"); break;
                case '\n': literal.Append(@"\n"); break;
                case '\r': literal.Append(@"\r"); break;
                case '\t': literal.Append(@"\t"); break;
                case '\v': literal.Append(@"\v"); break;
                default:
                    // ASCII printable character
                    if (c >= 0x20 && c <= 0x7e) {
                        literal.Append(c);
                    // As UTF16 escaped character
                    } else {
                        literal.Append(@"\u");
                        literal.Append(((int)c).ToString("x4"));
                    }
                    break;
            }
        }
        literal.Append("\"");
        return literal.ToString();
    }

copied from polyfill Array.prototype.find code of Array.find, and added the array as first parameter.

you can pass the search term as predicate function

// Example_x000D_
var listOfObjects = [{key: "1", value: "one"}, {key: "2", value: "two"}]_x000D_
var result = findInArray(listOfObjects, function(element) {_x000D_
  return element.key == "1";_x000D_
});_x000D_
console.log(result);_x000D_

// the function you want_x000D_
function findInArray(listOfObjects, predicate) {_x000D_
      if (listOfObjects == null) {_x000D_

Additionally, if your application uses SQL SERVER you can use the SQL Agent to schedule your tasks. This is where we commonly put re-occurring code that is data driven (email reminders, scheduled maintenance, purges, etc...). A great feature that is built in with the SQL Agent is failure notification options, which can alert you if a critical task fails.

In Visual Studio: Properties -> Advanced -> Entry Point -> write just the name of the function you want the program to begin running from, case sensitive, without any brackets and command line arguments.

Password boxes are also textboxes, so if you need them too:

$("input[type='text'], textarea, input[type='password']").css({width: "90%"});

and while file-input is a bit different, you may want to include them too (eg. for visual consistency):

$("input[type='text'], textarea, input[type='password'], input[type='file']").css({width: "90%"});

When we compare C++ with Java, we see that C++ was not designed with implicit Garbage Collection in mind, while Java was.

Having things like arbitrary pointers in C-Style is not only bad for GC-implementations, but it would also destroy backward compatibility for a large amount of C++-legacy-code.

In addition to that, C++ is a language that is intended to run as standalone executable instead of having a complex run-time environment.

All in all: Yes it might be possible to add Garbage Collection to C++, but for the sake of continuity it is better not to do so.

The solution of Rohan will fix the problem as the error message will not be shown but the emulator will not use the hardware acceleration and thus be again very slow.

I recommend instead to install the Intel Hardware Accelerated Execution Manager as described here:

On my machine using Node.js, I ran the following:

console.log('Testing Array:');
console.time('using[]');
for(var i=0; i<200000000; i++){var arr = []};
console.timeEnd('using[]');

console.time('using new');
for(var i=0; i<200000000; i++){var arr = new Array};
console.timeEnd('using new');

console.log('Testing Object:');

console.time('using{}');
for(var i=0; i<200000000; i++){var obj = {}};
console.timeEnd('using{}');

console.time('using new');
for(var i=0; i<200000000; i++){var obj = new Object};
console.timeEnd('using new');

Note, this is an extension of what is found here: Why is arr = [] faster than arr = new Array?

my output was the following:

Testing Array:
using[]: 1091ms
using new: 2286ms
Testing Object:
using{}: 870ms
using new: 5637ms

so clearly {} and [] are faster than using new for creating empty objects/arrays.

I've seen three results to a ping - The one we "want" where the IP replies, "Host Unreachable" and "timed out" (not sure of exact wording).

The first two return ERRORLEVEL of 0.

Timeout returns ERRORLEVEL of 1.

Are the other results and error levels that might be returned? (Besides using an invalid switch which returns the allowable switches and an errorlevel of 1.)

Apparently Host Unreachable can use one of the previously posted methods (although it's hard to figure out when someone replies which case they're writing code for) but does the timeout get returned in a similar manner that it can be parsed?

In general, how does one know what part of the results of the ping can be parsed? (Ie, why might Sent and/or Received and/or TTL be parseable, but not host unreachable?

Oh, and iSid, maybe there aren't many upvotes because the people that read this don't have enough points. So they get their question answered (or not) and leave.

I wasn't posting the above as an answer. It should have been a comment but I didn't see that choice.

What you're talking about is becoming a payment service provider. I have been there and done that. It was a lot easier about 10 years ago than it is now, but if you have a phenomenal amount of time, money and patience available, it is still possible.

You will need to contact an acquiring bank. You didnt say what region of the world you are in, but by this I dont mean a local bank branch. Each major bank will generally have a separate card acquiring arm. So here in the UK we have (eg) Natwest bank, which uses Streamline (or Worldpay) as its acquiring arm. In total even though we have scores of major banks, they all end up using one of five or so card acquirers.

Happily, all UK card acquirers use a standard protocol for communication of authorisation requests, and end of day settlement. You will find minor quirks where some acquiring banks support some features and have slightly different syntax, but the differences are fairly minor. The UK standards are published by the Association for Payment Clearing Services (APACS) (which is now known as the UKPA). The standards are still commonly referred to as APACS 30 (authorization) and APACS 29 (settlement), but are now formally known as APACS 70 (books 1 through 7).

Although the APACS standard is widely supported across the UK (Amex and Discover accept messages in this format too) it is not used in other countries - each country has it's own - for example: Carte Bancaire in France, CartaSi in Italy, Sistema 4B in Spain, Dankort in Denmark etc. An effort is under way to unify the protocols across Europe - see EPAS.org

Communicating with the acquiring bank can be done a number of ways. Again though, it will depend on your region. In the UK (and most of Europe) we have one communications gateway that provides connectivity to all the major acquirers, they are called TNS and there are dozens of ways of communicating through them to the acquiring bank, from dialup 9600 baud modems, ISDN, HTTPS, VPN or dedicated line. Ultimately the authorisation request will be converted to X25 protocol, which is the protocol used by these acquiring banks when communicating with each other.

In summary then: it all depends on your region.

• Contact a major bank and try to get through to their card acquiring arm.
• Explain that you're setting up as a payment service provider, and request details on comms format for authorization requests and end of day settlement files
• Set up a test merchant account and develop auth/settlement software and go through the accreditation process. Most acquirers help you through this process for free, but when you want to register as an accredited PSP some will request a fee.
• you will need to comply with some regulations too, for example you may need to register as a payment institution

Once you are registered and accredited you'll then be able to accept customers and set up merchant accounts on behalf of the bank/s you're accredited against (bearing in mind that each acquirer will generally support multiple banks). Rinse and repeat with other acquirers as you see necessary.

Beyond that you have lots of other issues, mainly dealing with PCI-DSS. Thats a whole other topic and there are already some q&a's on this site regarding that. Like I say, its a phenomenal undertaking - most likely a multi-year project even for a reasonably sized team, but its certainly possible.

I have encountered with same issue. When I changed content type it has solved. I'm not sure this solution will help you but maybe it is. If you don't mind about content-type, it worked for me.

axios.defaults.headers.post['Content-Type'] ='application/x-www-form-urlencoded';

Marshal.Copy works but is rather slow. Faster is to copy the bytes in a for loop. Even faster is to cast the byte array to a ulong array, copy as much ulong as fits in the byte array, then copy the possible remaining 7 bytes (the trail that is not 8 bytes aligned). Fastest is to pin the byte array in a fixed statement as proposed above in Tyalis' answer.

The file google-services.json should be pasted in the app/ directory. After this is when I sync the project with gradle file the unexpected Top level exception error comes. This is occurring because:

Project-Level Gradle File having

dependencies {
    classpath 'com.android.tools.build:gradle:1.0.0'
    classpath 'com.google.gms:google-services:1.3.0-beta1'
}

and App-Level Gradle File having:

    compile 'com.android.support:appcompat-v7:22.1.1'
    compile 'com.google.android.gms:play-services:7.5.0' // commenting this lineworks for me
}

The top line is creating a conflict between this and classpath 'com.google.gms:google-services:1.3.0-beta1' So I make comment it now it works Fine and no error of File google-services.json is missing from module root folder. The Google Quickstart Plugin cannot function without it.

There are 3 steps that needs to be run.

1. Register your app's client id from Google API console
2. Ask your end user to give consent using this api https://developers.google.com/identity/protocols/OpenIDConnect#sendauthrequest
3. Use google's oauth2 api as described at https://any-api.com/googleapis_com/oauth2/docs/userinfo/oauth2_userinfo_v2_me_get using the token obtained in step 2. (Though still I could not find how to fill "fields" parameter properly).

It is very interesting that this simplest usage is not clearly described anywhere. And i believe there is a danger, you should pay attention to the verified_emailparameter coming in the response. Because if I am not wrong it may yield fake emails to register your application. (This is just my interpretation, has a fair chance that I may be wrong!)

I find facebook's OAuth mechanics much much clearly described.

You are using a table variable i.e. you should declare the table. This is not a temporary table.

You create a temp table like so:

CREATE TABLE #customer
(
     Name varchar(32) not null
)

You declare a table variable like so:

DECLARE @Customer TABLE
(
      Name varchar(32) not null
)

Notice that a temp table is declared using # and a table variable is declared using a @. Go read about the difference between table variables and temp tables.

UPDATE:

Based on your comment below you are actually trying to create tables in a stored procedure. For this you would need to use dynamic SQL. Basically dynamic SQL allows you to construct a SQL Statement in the form of a string and then execute it. This is the ONLY way you will be able to create a table in a stored procedure. I am going to show you how and then discuss why this is not generally a good idea.

Now for a simple example (I have not tested this code but it should give you a good indication of how to do it):

CREATE PROCEDURE sproc_BuildTable 
    @TableName NVARCHAR(128)
   ,@Column1Name NVARCHAR(32)
   ,@Column1DataType NVARCHAR(32)
   ,@Column1Nullable NVARCHAR(32)
AS

   DECLARE @SQLString NVARCHAR(MAX)
   SET @SQString = 'CREATE TABLE '+@TableName + '( '+@Column1Name+' '+@Column1DataType +' '+@Column1Nullable +') ON PRIMARY '

   EXEC (@SQLString)
   GO

This stored procedure can be executed like this:

sproc_BuildTable 'Customers','CustomerName','VARCHAR(32)','NOT NULL'

There are some major problems with this type of stored procedure.

Its going to be difficult to cater for complex tables. Imagine the following table structure:

CREATE TABLE [dbo].[Customers] (
    [CustomerID] [int] IDENTITY(1,1) NOT NULL,
    [CustomerName] [nvarchar](64) NOT NULL,
    [CustomerSUrname] [nvarchar](64) NOT NULL,
    [CustomerDateOfBirth] [datetime] NOT NULL,
    [CustomerApprovedDiscount] [decimal](3, 2) NOT NULL,
    [CustomerActive] [bit] NOT NULL,
    CONSTRAINT [PK_Customers] PRIMARY KEY CLUSTERED 
    (
        [CustomerID] ASC
    ) WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF,      ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]
GO

ALTER TABLE [dbo].[Customers] ADD CONSTRAINT [DF_Customers_CustomerApprovedDiscount] DEFAULT ((0.00)) FOR [CustomerApprovedDiscount]
GO 

This table is a little more complex than the first example, but not a lot. The stored procedure will be much, much more complex to deal with. So while this approach might work for small tables it is quickly going to be unmanageable.

Creating tables require planning. When you create tables they should be placed strategically on different filegroups. This is to ensure that you don't cause disk I/O contention. How will you address scalability if everything is created on the primary file group?

Could you clarify why you need tables to be created dynamically?

UPDATE 2:

Delayed update due to workload. I read your comment about needing to create a table for each shop and I think you should look at doing it like the example I am about to give you.

In this example I make the following assumptions:

1. It's an e-commerce site that has many shops
2. A shop can have many items (goods) to sell.
3. A particular item (good) can be sold at many shops
4. A shop will charge different prices for different items (goods)
5. All prices are in $ (USD)

Let say this e-commerce site sells gaming consoles (i.e. Wii, PS3, XBOX360).

Looking at my assumptions I see a classical many-to-many relationship. A shop can sell many items (goods) and items (goods) can be sold at many shops. Let's break this down into tables.

First I would need a shop table to store all the information about the shop.

A simple shop table might look like this:

CREATE TABLE [dbo].[Shop](
    [ShopID] [int] IDENTITY(1,1) NOT NULL,
    [ShopName] [nvarchar](128) NOT NULL,
    CONSTRAINT [PK_Shop] PRIMARY KEY CLUSTERED 
    (
      [ShopID] ASC
    ) WITH (
              PAD_INDEX  = OFF
              , STATISTICS_NORECOMPUTE  = OFF
              , IGNORE_DUP_KEY = OFF
              , ALLOW_ROW_LOCKS  = ON
              , ALLOW_PAGE_LOCKS  = ON
    ) ON [PRIMARY]
    ) ON [PRIMARY]

    GO

Let's insert three shops into the database to use during our example. The following code will insert three shops:

INSERT INTO Shop
SELECT 'American Games R US'
UNION
SELECT 'Europe Gaming Experience'
UNION
SELECT 'Asian Games Emporium'

If you execute a SELECT * FROM Shop you will probably see the following:

ShopID  ShopName
1           American Games R US
2           Asian Games Emporium
3           Europe Gaming Experience

Right, so now let's move onto the Items (goods) table. Since the items/goods are products of various companies I am going to call the table product. You can execute the following code to create a simple Product table.

CREATE TABLE [dbo].[Product](
    [ProductID] [int] IDENTITY(1,1) NOT NULL,
    [ProductDescription] [nvarchar](128) NOT NULL,
 CONSTRAINT [PK_Product] PRIMARY KEY CLUSTERED 
 (
     [ProductID] ASC
 )WITH (PAD_INDEX  = OFF
        , STATISTICS_NORECOMPUTE  = OFF
        , IGNORE_DUP_KEY = OFF
        ,     ALLOW_ROW_LOCKS  = ON
         , ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
  ) ON [PRIMARY]

GO

Let's populate the products table with some products. Execute the following code to insert some products:

INSERT INTO Product
SELECT 'Wii'
UNION 
SELECT 'PS3'
UNION 
SELECT 'XBOX360'

If you execute SELECT * FROM Product you will probably see the following:

ProductID   ProductDescription
1           PS3
2           Wii
3           XBOX360

OK, at this point you have both product and shop information. So how do you bring them together? Well we know we can identify the shop by its ShopID primary key column and we know we can identify a product by its ProductID primary key column. Also, since each shop has a different price for each product we need to store the price the shop charges for the product.

So we have a table that maps the Shop to the product. We will call this table ShopProduct. A simple version of this table might look like this:

CREATE TABLE [dbo].[ShopProduct](
[ShopID] [int] NOT NULL,
[ProductID] [int] NOT NULL,
[Price] [money] NOT NULL,
CONSTRAINT [PK_ShopProduct] PRIMARY KEY CLUSTERED 
 (
     [ShopID] ASC,
      [ProductID] ASC
 )WITH (PAD_INDEX  = OFF,
     STATISTICS_NORECOMPUTE  = OFF, 
     IGNORE_DUP_KEY = OFF, 
     ALLOW_ROW_LOCKS  = ON,
     ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
  ) ON [PRIMARY]

 GO

So let's assume the American Games R Us shop only sells American consoles, the Europe Gaming Experience sells all consoles and the Asian Games Emporium sells only Asian consoles. We would need to map the primary keys from the shop and product tables into the ShopProduct table.

Here is how we are going to do the mapping. In my example the American Games R Us has a ShopID value of 1 (this is the primary key value) and I can see that the XBOX360 has a value of 3 and the shop has listed the XBOX360 for $159.99

By executing the following code you would complete the mapping:

INSERT INTO ShopProduct VALUES(1,3,159.99)

Now we want to add all product to the Europe Gaming Experience shop. In this example we know that the Europe Gaming Experience shop has a ShopID of 3 and since it sells all consoles we will need to insert the ProductID 1, 2 and 3 into the mapping table. Let's assume the prices for the consoles (products) at the Europe Gaming Experience shop are as follows: 1- The PS3 sells for $259.99 , 2- The Wii sells for $159.99 , 3- The XBOX360 sells for $199.99.

To get this mapping done you would need to execute the following code:

INSERT INTO ShopProduct VALUES(3,2,159.99) --This will insert the WII console into the mapping table for the Europe Gaming Experience Shop with a price of 159.99
INSERT INTO ShopProduct VALUES(3,1,259.99) --This will insert the PS3 console into the mapping table for the Europe Gaming Experience Shop with a price of 259.99
INSERT INTO ShopProduct VALUES(3,3,199.99) --This will insert the XBOX360 console into the mapping table for the Europe Gaming Experience Shop with a price of 199.99

At this point you have mapped two shops and their products into the mapping table. OK, so now how do I bring this all together to show a user browsing the website? Let's say you want to show all the product for the European Gaming Experience to a user on a web page – you would need to execute the following query:

SELECT      Shop.*
        , ShopProduct.*
        , Product.*
FROM         Shop 
INNER JOIN  ShopProduct ON Shop.ShopID = ShopProduct.ShopID 
INNER JOIN  Product ON ShopProduct.ProductID = Product.ProductID
WHERE       Shop.ShopID=3

You will probably see the following results:

ShopID     ShopName                 ShopID  ProductID   Price   ProductID   ProductDescription
3          Europe Gaming Experience   3         1       259.99  1           PS3
3          Europe Gaming Experience   3         2       159.99  2           Wii
3          Europe Gaming Experience   3         3       199.99  3           XBOX360

Now for one last example, let's assume that your website has a feature which finds the cheapest price for a console. A user asks to find the cheapest prices for XBOX360.

You can execute the following query:

 SELECT     Shop.*
        , ShopProduct.*
        , Product.*
 FROM         Shop 
 INNER JOIN  ShopProduct ON Shop.ShopID = ShopProduct.ShopID 
 INNER JOIN  Product ON ShopProduct.ProductID = Product.ProductID
 WHERE      Product.ProductID =3  -- You can also use Product.ProductDescription = 'XBOX360'
 ORDER BY    Price ASC

This query will return a list of all shops which sells the XBOX360 with the cheapest shop first and so on.

You will notice that I have not added the Asian Games shop. As an exercise, add the Asian games shop to the mapping table with the following products: the Asian Games Emporium sells the Wii games console for $99.99 and the PS3 console for $159.99. If you work through this example you should now understand how to model a many-to-many relationship.

I hope this helps you in your travels with database design.

I also came across the same error. Here is the fix: If you are using Cmake-GUI:

1. Clean the cache of the loaded libraries in Cmake-GUI File menu.
2. Configure the libraries.
3. Generate the Unix file.

If you missed the 3rd step:

*** No rule to make target `install'. Stop.

error will occur.

Converting and removing annoying stars:

$array = (array) $object;
foreach($array as $key => $val)
{
    $new_array[str_replace('*_', '', $key)] = $val;
}

Probably, it will be cheaper than using reflections.

Note that if you split the variables into lines, you must use backslashes to wrap the newlines.

with A() as a, \
     B() as b, \
     C() as c:
    doSomething(a,b,c)

Parentheses don't work, since Python creates a tuple instead.

with (A(),
      B(),
      C()):
    doSomething(a,b,c)

Since tuples lack a __enter__ attribute, you get an error (undescriptive and does not identify class type):

AttributeError: __enter__

If you try to use as within parentheses, Python catches the mistake at parse time:

with (A() as a,
      B() as b,
      C() as c):
    doSomething(a,b,c)

SyntaxError: invalid syntax

When will this be fixed?

This issue is tracked in https://bugs.python.org/issue12782.

Recently, Python announced in PEP 617 that they'll be replacing the current parser with a new one. Because Python's current parser is LL(1), it cannot distinguish between "multiple context managers" with (A(), B()): and "tuple of values" with (A(), B())[0]:.

The new parser can properly parse "multiple context managers" surrounded by tuples. The new parser will be enabled in 3.9, but this syntax will still be rejected until the old parser is removed in Python 3.10.

I took aberke's solution and modified it to suit my taste.

• It produces a single input element
• It optionally accepts extensions
• For US numbers it skips the leading country code
• Standard naming conventions
• Uses class from using code; doesn't make up a class
• Allows use of any other attributes allowed on an input element

We can implement ajax request by using http service in AngularJs, which helps to read/load data from remote server.

$http service methods are listed below,

 $http.get()
 $http.post()
 $http.delete()
 $http.head()
 $http.jsonp()
 $http.patch()
 $http.put()

One of the Example:

    $http.get("sample.php")
        .success(function(response) {
            $scope.getting = response.data; // response.data is an array
    }).error(){

        // Error callback will trigger
    });

http://www.drtuts.com/ajax-requests-angularjs/

Something else you can try if you are having issues encoding to 'utf-8' and want to go cell by cell you could try the following.

Python 2

(Where "df" is your DataFrame object.)

for column in df.columns:
    for idx in df[column].index:
        x = df.get_value(idx,column)
        try:
            x = unicode(x.encode('utf-8','ignore'),errors ='ignore') if type(x) == unicode else unicode(str(x),errors='ignore')
            df.set_value(idx,column,x)
        except Exception:
            print 'encoding error: {0} {1}'.format(idx,column)
            df.set_value(idx,column,'')
            continue

Then try:

df.to_csv(file_name)

You can check the encoding of the columns by:

for column in df.columns:
    print '{0} {1}'.format(str(type(df[column][0])),str(column))

Warning: errors='ignore' will just omit the character e.g.

IN: unicode('Regenexx\xae',errors='ignore')
OUT: u'Regenexx'

Python 3

for column in df.columns:
    for idx in df[column].index:
        x = df.get_value(idx,column)
        try:
            x = x if type(x) == str else str(x).encode('utf-8','ignore').decode('utf-8','ignore')
            df.set_value(idx,column,x)
        except Exception:
            print('encoding error: {0} {1}'.format(idx,column))
            df.set_value(idx,column,'')
            continue

You can try this as well, it is easy to implement

TimeZone time2 = TimeZone.CurrentTimeZone;
DateTime test = time2.ToUniversalTime(DateTime.Now);
var singapore = TimeZoneInfo.FindSystemTimeZoneById("Singapore Standard Time");
var singaporetime = TimeZoneInfo.ConvertTimeFromUtc(test, singapore);

Change the text to which standard time you want to change.

Use TimeZone feature of C# to implement.

If you want to change MSSQL server language, you can use the following QUERY:

EXEC sp_configure 'default language', 'British English';

In oracle db there is a trick for casting int to float (I suppose, it should also work in mysql):

select myintfield + 0.0 as myfloatfield from mytable

While @Heximal's answer works, I don't personally recommend it.

This is because it uses implicit casting. Although you didn't type CAST, either the SUM() or the 0.0 need to be cast to be the same data-types, before the + can happen. In this case the order of precedence is in your favour, and you get a float on both sides, and a float as a result of the +. But SUM(aFloatField) + 0 does not yield an INT, because the 0 is being implicitly cast to a FLOAT.

I find that in most programming cases, it is much preferable to be explicit. Don't leave things to chance, confusion, or interpretation.

If you want to be explicit, I would use the following.

CAST(SUM(sl.parts) AS FLOAT) * cp.price
-- using MySQL CAST FLOAT  requires 8.0

You can try the following to see what happens...

CAST(SUM(sl.parts) AS NUMERIC(10,4)) * CAST(cp.price AS NUMERIC(10,4))

As with many tasks in ggplot, the general strategy is to put what you'd like to add to the plot into a data frame in a way such that the variables match up with the variables and aesthetics in your plot. So for example, you'd create a new data frame like this:

dfTab <- as.data.frame(table(df))
colnames(dfTab)[1] <- "x"
dfTab$lab <- as.character(100 * dfTab$Freq / sum(dfTab$Freq))

So that the x variable matches the corresponding variable in df, and so on. Then you simply include it using geom_text:

ggplot(df) + geom_bar(aes(x,fill=x)) + 
    geom_text(data=dfTab,aes(x=x,y=Freq,label=lab),vjust=0) +
    opts(axis.text.x=theme_blank(),axis.ticks=theme_blank(),
        axis.title.x=theme_blank(),legend.title=theme_blank(),
        axis.title.y=theme_blank())

This example will plot just the percentages, but you can paste together the counts as well via something like this:

dfTab$lab <- paste(dfTab$Freq,paste("(",dfTab$lab,"%)",sep=""),sep=" ")

Note that in the current version of ggplot2, opts is deprecated, so we would use theme and element_blank now.

The getFilesDir() somehow didn't work. Using a method, which returns the entire path and filename gave the desired result. Here is the code:

File file = new File(inputHandle.getImgPath(id));
boolean deleted = file.delete();

<html>
<div style="width:100%; height:100%; position:fixed; left:0;top:0;overflow:hidden;">

</div>
</html>

1. Download the file from http://www.java2s.com/Code/Jar/STUVWXYZ/Downloadjavaxservletjar.htm

2. Make a folder ("lib") inside the project folder and move that jar file to there.

3. In Eclipse, right click on project > BuildPath > Configure BuildPath > Libraries > Add External Jar

Thats all

Try this

@Override
public boolean onCreateOptionsMenu(Menu menu){
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.custom_actionbar, menu);
    menu.setGroupVisible(...);
}

getClass().getResourcesAsStream() works fine on Android. Just make sure the file you are trying to open is correctly embedded in your APK (open the APK as ZIP).

Normally on Android you put such files in the assets directory. So if you put the raw_resources.dat in the assets subdirectory of your project, it will end up in the assets directory in the APK and you can use:

getClass().getResourcesAsStream("/assets/raw_resources.dat");

It is also possible to customize the build process so that the file doesn't land in the assets directory in the APK.

GCM/APNS are only for Chrome and Safari respectively.

I think you may be looking for Notification:

https://developer.mozilla.org/en-US/docs/Web/API/notification

It works in Chrome, Firefox, Opera and Safari.

If you just want to get the information of current directory, you can type:

pwd

and you don't need to use the Nautilus, or you can use a teamviewer software to remote connect to the computer, you can get everything you want.

I use this chrome extension. It'll give you the wget command for any download link you open.

I haven't really seen many practical real world uses of the %n specifier, but I remember that it was used in oldschool printf vulnerabilities with a format string attack quite a while back.

Something that went like this

void authorizeUser( char * username, char * password){

    ...code here setting authorized to false...
    printf(username);

    if ( authorized ) {
         giveControl(username);
    }
}

where a malicious user could take advantage of the username parameter getting passed into printf as the format string and use a combination of %d, %c or w/e to go through the call stack and then modify the variable authorized to a true value.

Yeah it's an esoteric use, but always useful to know when writing a daemon to avoid security holes? :D

You should use "getdents" in place of ls/find

Here is one very good article which described the getdents approach.

http://be-n.com/spw/you-can-list-a-million-files-in-a-directory-but-not-with-ls.html

Here is the extract:

ls and practically every other method of listing a directory (including Python's os.listdir and find .) rely on libc readdir(). However, readdir() only reads 32K of directory entries at a time, which means that if you have a lot of files in the same directory (e.g., 500 million directory entries) it is going to take an insanely long time to read all the directory entries, especially on a slow disk. For directories containing a large number of files, you'll need to dig deeper than tools that rely on readdir(). You will need to use the getdents() system call directly, rather than helper methods from the C standard library.

We can find the C code to list the files using getdents() from here:

There are two modifications you will need to do in order quickly list all the files in a directory.

First, increase the buffer size from X to something like 5 megabytes.

#define BUF_SIZE 1024*1024*5

Then modify the main loop where it prints out the information about each file in the directory to skip entries with inode == 0. I did this by adding

if (dp->d_ino != 0) printf(...);

In my case I also really only cared about the file names in the directory so I also rewrote the printf() statement to only print the filename.

if(d->d_ino) printf("%sn ", (char *) d->d_name);

Compile it (it doesn't need any external libraries, so it's super simple to do)

gcc listdir.c -o listdir

Now just run

./listdir [directory with an insane number of files]

psutil provides a portable way that doesn't use environment variables like the getpass solution. It is less prone to security issues, and should probably be the accepted answer as of today.

import psutil

def get_username():
    return psutil.Process().username()

Under the hood, this combines the getpwuid based method for unix and the GetTokenInformation method for Windows.

It works like a charm in PhpStorm

Solution

import UIKit

extension UIView {

    func removeConstraints() { removeConstraints(constraints) }
    func deactivateAllConstraints() { NSLayoutConstraint.deactivate(getAllConstraints()) }
    func getAllSubviews() -> [UIView] { return UIView.getAllSubviews(view: self) }

    func getAllConstraints() -> [NSLayoutConstraint] {
        var subviewsConstraints = getAllSubviews().flatMap { $0.constraints }
        if let superview = self.superview {
            subviewsConstraints += superview.constraints.compactMap { (constraint) -> NSLayoutConstraint? in
                if let view = constraint.firstItem as? UIView, view == self { return constraint }
                return nil
            }
        }
        return subviewsConstraints + constraints
    }

    class func getAllSubviews(view: UIView) -> [UIView] {
        return view.subviews.flatMap { [$0] + getAllSubviews(view: $0) }
    }
}

Usage

print("constraints: \(view.getAllConstraints().count), subviews: \(view.getAllSubviews().count)")
view.deactivateAllConstraints()

I'm not sure, what you mean as the 'mobile width'. But in each case, the CSS @media can be used for hiding elements in the screen width basis. See some example:

<div id="my-content"></div>

...and:

@media screen and (min-width: 0px) and (max-width: 400px) {
  #my-content { display: block; }  /* show it on small screens */
}

@media screen and (min-width: 401px) and (max-width: 1024px) {
  #my-content { display: none; }   /* hide it elsewhere */
}

Some truly mobile detection is kind of hard programming and rather difficult. Eventually see the: http://detectmobilebrowsers.com/ or other similar sources.

These are what's known as Shadow Copy Folders.

Simplistically....and I really mean it:

When ASP.NET runs your app for the first time, it copies any assemblies found in the /bin folder, copies any source code files (found for example in the App_Code folder) and parses your aspx, ascx files to c# source files. ASP.NET then builds/compiles all this code into a runnable application.

One advantage of doing this is that it prevents the possibility of .NET assembly DLL's #(in the /bin folder) becoming locked by the ASP.NET worker process and thus not updatable.

ASP.NET watches for file changes in your website and will if necessary begin the whole process all over again.

Theoretically the folder shouldn't need any maintenance, but from time to time, and only very rarely you may need to delete contents. That said, I work for a hosting company, we run up to 1200 sites per shared server and I haven't had to touch this folder on any of the 250 or so machines for years.

This is outlined in the MSDN article Understanding ASP.NET Dynamic Compilation

In addition to Roman's answer, something like this might be even simpler. Note that I haven't tested it because I do not have access to R right now.

# Note that I use a global variable here
# normally not advisable, but I liked the
# use here to make the code shorter
index <<- 0
new_column = sapply(df$h_no, function(x) {
  if(x == 1) index = index + 1
  return(index)
})

The function iterates over the values in n_ho and always returns the categorie that the current value belongs to. If a value of 1 is detected, we increase the global variable index and continue.

Well, there is an array type in recent Postgres versions (not 100% about PG 7.4). You can even index them, using a GIN or GIST index. The syntaxes are:

create table foo (
  bar  int[] default '{}'
);

select * from foo where bar && array[1] -- equivalent to bar && '{1}'::int[]

create index on foo using gin (bar); -- allows to use an index in the above query

But as the prior answer suggests, it will be better to normalize properly.

Follow this, it can be like what you are looking:

var obj = {_x000D_
    Objone: 'one',_x000D_
    Objtwo: 'two'_x000D_
};_x000D_
_x000D_
var key = "Objone";_x000D_
delete obj[key];_x000D_
console.log(obj); // prints { "objtwo": two}

You have to use max-width instead of min-width.

<style>
    @media (max-width: 1026px) {
        #test {
            display: none;
        }
    }
</style>
<div id="test">
    <h1>Test</h1>
</div>

Right. The function you pass to getLocations() won't get called until the data is available, so returning "country" before it's been set isn't going to help you.

The way you need to do this is to have the function that you pass to geocoder.getLocations() actually do whatever it is you wanted done with the returned values.

Something like this:

function reverseGeocode(latitude,longitude){
  var geocoder = new GClientGeocoder();
  var latlng = new GLatLng(latitude, longitude);

  geocoder.getLocations(latlng, function(addresses) {
    var address = addresses.Placemark[0].address;
    var country = addresses.Placemark[0].AddressDetails.Country.CountryName;
    var countrycode = addresses.Placemark[0].AddressDetails.Country.CountryNameCode;
    var locality = addresses.Placemark[0].AddressDetails.Country.AdministrativeArea.SubAdministrativeArea.Locality.LocalityName;
    do_something_with_address(address, country, countrycode, locality);
  });   
}

function do_something_with_address(address, country, countrycode, locality) {
  if (country==="USA") {
     alert("USA A-OK!"); // or whatever
  }
}

If you might want to do something different every time you get the location, then pass the function as an additional parameter to reverseGeocode:

function reverseGeocode(latitude,longitude, callback){
  // Function contents the same as above, then
  callback(address, country, countrycode, locality);
}
reverseGeocode(latitude, longitude, do_something_with_address);

If this looks a little messy, then you could take a look at something like the Deferred feature in Dojo, which makes the chaining between functions a little clearer.

Support for the extended ternary operator was added in Twig 1.12.0.

1. If foo echo yes else echo no:

   {{ foo ? 'yes' : 'no' }}
   

2. If foo echo it, else echo no:

   {{ foo ?: 'no' }}
   

   or

   {{ foo ? foo : 'no' }}
   

3. If foo echo yes else echo nothing:

   {{ foo ? 'yes' }}
   

   or

   {{ foo ? 'yes' : '' }}
   

4. Returns the value of foo if it is defined and not null, no otherwise:

   {{ foo ?? 'no' }}
   

5. Returns the value of foo if it is defined (empty values also count), no otherwise:

   {{ foo|default('no') }}
   

You have to cast, I'm afraid:

f((byte)0);

I believe that will perform the appropriate conversion at compile-time instead of execution time, so it's not actually going to cause performance penalties. It's just inconvenient :(

using XML, you need to set the onclick listener yourself. First have your class implements OnClickListener then add the variable Button button1; then add this to your onCreate()

button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(this);

when you implement OnClickListener you need to add the inherited method onClick() where you will handle your clicks

tl;dr

To keep Map< Integer , String > in an order sorted by key, use either of the two classes implementing the SortedMap/NavigableMap interfaces:

• TreeMap
• ConcurrentSkipListMap

If manipulating the map within a single thread, use the first, TreeMap. If manipulating across threads, use the second, ConcurrentSkipListMap.

For details, see the table below and the following discussion.

Details

Here is a graphic table I made showing the features of the ten Map implementations bundled with Java 11.

The NavigableMap interface is what SortedMap should have been in the first place. The SortedMap logically should be removed but cannot be as some 3rd-party map implementations may be using interface.

As you can see in this table, only two classes implement the SortedMap/NavigableMap interfaces:

• TreeMap
• ConcurrentSkipListMap

Both of these keep keys in sorted order, either by their natural order (using compareTo method of the Comparable(https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/Comparable.html) interface) or by a Comparator implementation you pass. The difference between these two classes is that the second one, ConcurrentSkipListMap, is thread-safe, highly concurrent.

See also the Iteration order column in the table below.

• The LinkedHashMap class returns its entries by the order in which they were originally inserted.
• EnumMap returns entries in the order by which the enum class of the key is defined. For example, a map of which employee is covering which day of the week (Map< DayOfWeek , Person >) uses the DayOfWeek enum class built into Java. That enum is defined with Monday first and Sunday last. So entries in an iterator will appear in that order.

The other six implementations make no promise about the order in which they report their entries.

>>> a = np.random.randint(0, 5, size=(5, 4))
>>> a
array([[0, 3, 3, 2],
       [4, 1, 1, 2],
       [3, 4, 2, 4],
       [2, 4, 3, 0],
       [1, 2, 3, 4]])
>>> 
>>> a[a > 3] = -101
>>> a
array([[   0,    3,    3,    2],
       [-101,    1,    1,    2],
       [   3, -101,    2, -101],
       [   2, -101,    3,    0],
       [   1,    2,    3, -101]])
>>>

See, eg, Indexing with boolean arrays.

There are different ways to delete an array element, where some are more useful for some specific tasks than others.

Deleting a single array element

If you want to delete just one array element you can use unset() or alternatively \array_splice().

If you know the value and don’t know the key to delete the element you can use \array_search() to get the key. This only works if the element does not occur more than once, since \array_search returns the first hit only.

unset()

Note that when you use unset() the array keys won’t change. If you want to reindex the keys you can use \array_values() after unset(), which will convert all keys to numerically enumerated keys starting from 0.

Code:

$array = [0 => "a", 1 => "b", 2 => "c"];
unset($array[1]);
          // ? Key which you want to delete

Output:

[
    [0] => a
    [2] => c
]

\array_splice() method

If you use \array_splice() the keys will automatically be reindexed, but the associative keys won’t change — as opposed to \array_values(), which will convert all keys to numerical keys.

\array_splice() needs the offset, not the key, as the second parameter.

Code:

$array = [0 => "a", 1 => "b", 2 => "c"];
\array_splice($array, 1, 1);
                   // ? Offset which you want to delete

Output:

[
    [0] => a
    [1] => c
]

array_splice(), same as unset(), take the array by reference. You don’t assign the return values of those functions back to the array.

Deleting multiple array elements

If you want to delete multiple array elements and don’t want to call unset() or \array_splice() multiple times you can use the functions \array_diff() or \array_diff_key() depending on whether you know the values or the keys of the elements which you want to delete.

\array_diff() method

If you know the values of the array elements which you want to delete, then you can use \array_diff(). As before with unset() it won’t change the keys of the array.

Code:

$array = [0 => "a", 1 => "b", 2 => "c", 3 => "c"];
$array = \array_diff($array, ["a", "c"]);
                          // +--------+
                          // Array values which you want to delete

Output:

[
    [1] => b
]

\array_diff_key() method

If you know the keys of the elements which you want to delete, then you want to use \array_diff_key(). You have to make sure you pass the keys as keys in the second parameter and not as values. Keys won’t reindex.

Code:

$array = [0 => "a", 1 => "b", 2 => "c"];
$array = \array_diff_key($array, [0 => "xy", "2" => "xy"]);
                               // ?           ?
                               // Array keys which you want to delete

Output:

[
    [1] => b
]

If you want to use unset() or \array_splice() to delete multiple elements with the same value you can use \array_keys() to get all the keys for a specific value and then delete all elements.

Actually I wanted same alike thing, To get one year backward date, for a given date! :-)

With the hint of above answer from @mohammad mohsenipur I got to the following link, via his given link!

Luckily, there is a method same as date_add method, named date_sub method! :-) I do the following to get done what I wanted!

$date = date_create('2000-01-01');
date_sub($date, date_interval_create_from_date_string('1 years'));
echo date_format($date, 'Y-m-d');

Hopes this answer will help somebody too! :-)

Good luck guys!

Use Thread.Sleep when you want to block the current thread.

Use Task.Delay when you want a logical delay without blocking the current thread.

Efficiency should not be a paramount concern with these methods. Their primary real-world use is as retry timers for I/O operations, which are on the order of seconds rather than milliseconds.

Using the Date object's methods will could come in handy.

e.g.:

myDate = new Date();
plusSeven = new Date(myDate.setDate(myDate.getDate() + 7));

If you are willing to part with some money, JNIWrapper is a useful library with a Winpack, you will be able to get file system events on certain files. Unfortunately windows only.

Otherwise, resorting to native code is not always a bad thing especially when the best on offer is a polling mechanism as against a native event.

I've noticed that Java file system operations can be slow on some computers and can easily affect the application's performance if not handled well.

Real, User and Sys process time statistics

One of these things is not like the other. Real refers to actual elapsed time; User and Sys refer to CPU time used only by the process.

• Real is wall clock time - time from start to finish of the call. This is all elapsed time including time slices used by other processes and time the process spends blocked (for example if it is waiting for I/O to complete).

• User is the amount of CPU time spent in user-mode code (outside the kernel) within the process. This is only actual CPU time used in executing the process. Other processes and time the process spends blocked do not count towards this figure.

• Sys is the amount of CPU time spent in the kernel within the process. This means executing CPU time spent in system calls within the kernel, as opposed to library code, which is still running in user-space. Like 'user', this is only CPU time used by the process. See below for a brief description of kernel mode (also known as 'supervisor' mode) and the system call mechanism.

User+Sys will tell you how much actual CPU time your process used. Note that this is across all CPUs, so if the process has multiple threads (and this process is running on a computer with more than one processor) it could potentially exceed the wall clock time reported by Real (which usually occurs). Note that in the output these figures include the User and Sys time of all child processes (and their descendants) as well when they could have been collected, e.g. by wait(2) or waitpid(2), although the underlying system calls return the statistics for the process and its children separately.

Origins of the statistics reported by time (1)

The statistics reported by time are gathered from various system calls. 'User' and 'Sys' come from wait (2) (POSIX) or times (2) (POSIX), depending on the particular system. 'Real' is calculated from a start and end time gathered from the gettimeofday (2) call. Depending on the version of the system, various other statistics such as the number of context switches may also be gathered by time.

On a multi-processor machine, a multi-threaded process or a process forking children could have an elapsed time smaller than the total CPU time - as different threads or processes may run in parallel. Also, the time statistics reported come from different origins, so times recorded for very short running tasks may be subject to rounding errors, as the example given by the original poster shows.

A brief primer on Kernel vs. User mode

On Unix, or any protected-memory operating system, 'Kernel' or 'Supervisor' mode refers to a privileged mode that the CPU can operate in. Certain privileged actions that could affect security or stability can only be done when the CPU is operating in this mode; these actions are not available to application code. An example of such an action might be manipulation of the MMU to gain access to the address space of another process. Normally, user-mode code cannot do this (with good reason), although it can request shared memory from the kernel, which could be read or written by more than one process. In this case, the shared memory is explicitly requested from the kernel through a secure mechanism and both processes have to explicitly attach to it in order to use it.

The privileged mode is usually referred to as 'kernel' mode because the kernel is executed by the CPU running in this mode. In order to switch to kernel mode you have to issue a specific instruction (often called a trap) that switches the CPU to running in kernel mode and runs code from a specific location held in a jump table. For security reasons, you cannot switch to kernel mode and execute arbitrary code - the traps are managed through a table of addresses that cannot be written to unless the CPU is running in supervisor mode. You trap with an explicit trap number and the address is looked up in the jump table; the kernel has a finite number of controlled entry points.

The 'system' calls in the C library (particularly those described in Section 2 of the man pages) have a user-mode component, which is what you actually call from your C program. Behind the scenes, they may issue one or more system calls to the kernel to do specific services such as I/O, but they still also have code running in user-mode. It is also quite possible to directly issue a trap to kernel mode from any user space code if desired, although you may need to write a snippet of assembly language to set up the registers correctly for the call.

More about 'sys'

There are things that your code cannot do from user mode - things like allocating memory or accessing hardware (HDD, network, etc.). These are under the supervision of the kernel, and it alone can do them. Some operations like malloc orfread/fwrite will invoke these kernel functions and that then will count as 'sys' time. Unfortunately it's not as simple as "every call to malloc will be counted in 'sys' time". The call to malloc will do some processing of its own (still counted in 'user' time) and then somewhere along the way it may call the function in kernel (counted in 'sys' time). After returning from the kernel call, there will be some more time in 'user' and then malloc will return to your code. As for when the switch happens, and how much of it is spent in kernel mode... you cannot say. It depends on the implementation of the library. Also, other seemingly innocent functions might also use malloc and the like in the background, which will again have some time in 'sys' then.

I listed dates of 2 Weeks later. You can use variable @period OR function datediff(dd, @date_start, @date_end)

declare @period INT, @date_start datetime, @date_end datetime, @i int;

set @period = 14
set @date_start = convert(date,DATEADD(D, -@period, curent_timestamp))
set @date_end = convert(date,current_timestamp)
set @i = 1

create table #datesList(dts datetime)
insert into #datesList values (@date_start)
while @i <= @period
    Begin
        insert into #datesList values (dateadd(d,@i,@date_start))
        set @i = @i + 1
    end
select cast(dts as DATE) from #datesList
Drop Table #datesList

As some of the other answers have pointed out, the a element requires an href attribute and the # is used as a placeholder, but it is also a historical artifact.

From Mozilla Developer Network:

href

This was the single required attribute for anchors defining a hypertext source link, but is no longer required in HTML5. Omitting this attribute creates a placeholder link. The href attribute indicates the link target, either a URL or a URL fragment. A URL fragment is a name preceded by a hash mark (#), which specifies an internal target location (an ID) within the current document.

Also, per the HTML5 spec:

If the a element has no href attribute, then the element represents a placeholder for where a link might otherwise have been placed, if it had been relevant, consisting of just the element's contents.

Setting the launcher icons like a native developer

I was having some trouble using and understanding the flutter_launcher_icons package. This answer is how you would do it if you were creating an app for Android or iOS natively. It is pretty fast and easy once you have done it a few times.

Android

Android launcher icons have both a foreground and a background layer.

(image adapted from Android documentation)

The easiest way to create launcher icons for Android is to use the Asset Studio that is available right in Android Studio. You don't even have to leave your Flutter project. (VS Code users, you might consider using Android Studio just for this step. It's really very convenient and it doesn't hurt to be familiar with another IDE.)

Right click on the android folder in the project outline. Go to New > Image Asset. (Try right clicking the android/app folder if you don't see Image Asset as an option. Also see the comments below for more suggestions.) Now you can select an image to create your launcher icon from.

Note: I usually use a 1024x1024 pixel image but you should certainly use nothing smaller that 512x512. If you are using Gimp or Inkscape, you should have two layers, one for the foreground and one for the background. The foreground image should have transparent areas for the background layer to show through.

(lion clipart from here)

This will replace the current launcher icons. You can find the generated icons in the mipmap folders:

If you would prefer to create the launcher icons manually, see this answer for help.

Finally, make sure that the launcher icon name in the AndroidManifest is the same as what you called it above (ic_launcher by default):

application android:icon="@mipmap/ic_launcher"

Run the app in the emulator to confirm that the launcher icon was created successfully.

iOS

I always used to individually resize my iOS icons by hand, but if you have a Mac, there is a free app in the Mac App Store called Icon Set Creator. You give it an image (of at least 1024x1024 pixels) and it will spit out all the sizes that you need (plus the Contents.json file). Thanks to this answer for the suggestion.

iOS icons should not have any transparency. See more guidelines here.

After you have created the icon set, start Xcode (assuming you have a Mac) and use it to open the ios folder in your Flutter project. Then go to Runner > Assets.xcassets and delete the AppIcon item.

After that right-click and choose Import.... Choose the icon set that you just created.

That's it. Confirm that the icon was created by running the app in the simulator.

If you don't have a Mac...

You can still create all of the images by hand. In your Flutter project go to ios/Runner/Assets.xcassets/AppIcon.appiconset.

The image sizes that you need are the multiplied sizes in the filename. For example, [email protected] would be 29 times 3, that is, 87 pixels square. You either need to keep the same icon names or edit the JSON file.

DELETE FROM on_search 
WHERE search_date < UNIX_TIMESTAMP(DATE_SUB(NOW(), INTERVAL 180 DAY))

The logging module has everything you could want. It may seem excessive at first, but only use the parts you need. I'd recommend using logging.basicConfig to toggle the logging level to stderr and the simple log methods, debug, info, warning, error and critical.

import logging, sys
logging.basicConfig(stream=sys.stderr, level=logging.DEBUG)
logging.debug('A debug message!')
logging.info('We processed %d records', len(processed_records))

According to the Git documentation, the last argument of the git push command can be the repository that you want to push to:

    git push [--all | --mirror | --tags] [-n | --dry-run] [--receive-pack=<git-receive-pack>]
             [--repo=<repository>] [-f | --force] [--prune] [-v | --verbose] [-u | --set-upstream]
             [<repository> [<refspec>…]]

And the repository parameter can be either a URL or a remote name.

So you can specify username and password the same way as you do in your example of clone command.

The trick is to use useradd instead of its interactive wrapper adduser. I usually create users with:

RUN useradd -ms /bin/bash newuser

which creates a home directory for the user and ensures that bash is the default shell.

You can then add:

USER newuser
WORKDIR /home/newuser

to your dockerfile. Every command afterwards as well as interactive sessions will be executed as user newuser:

docker run -t -i image
newuser@131b7ad86360:~$

You might have to give newuser the permissions to execute the programs you intend to run before invoking the user command.

Using non-privileged users inside containers is a good idea for security reasons. It also has a few drawbacks. Most importantly, people deriving images from your image will have to switch back to root before they can execute commands with superuser privileges.

You can use a property setter to raise an event whenever the value of a field is going to change.

You can have your own EventHandler delegate or you can use the famous System.EventHandler delegate.

Usually there's a pattern for this:

1. Define a public event with an event handler delegate (that has an argument of type EventArgs).
2. Define a protected virtual method called OnXXXXX (OnMyPropertyValueChanged for example). In this method you should check if the event handler delegate is null and if not you can call it (it means that there are one or more methods attached to the event delegation).
3. Call this protected method whenever you want to notify subscribers that something has changed.

Here's an example

private int _age;

//#1
public event System.EventHandler AgeChanged;

//#2
protected virtual void OnAgeChanged()
{ 
     if (AgeChanged != null) AgeChanged(this,EventArgs.Empty); 
}

public int Age
{
    get
    {
         return _age;
    }

    set
    {
         //#3
         _age=value;
         OnAgeChanged();
    }
 }

The advantage of this approach is that you let any other classes that want to inherit from your class to change the behavior if necessary.

If you want to catch an event in a different thread that it's being raised you must be careful not to change the state of objects that are defined in another thread which will cause a cross thread exception to be thrown. To avoid this you can either use an Invoke method on the object that you want to change its state to make sure that the change is happening in the same thread that the event has been raised or in case that you are dealing with a Windows Form you can use a BackgourndWorker to do things in a parallel thread nice and easy.

var partsOfStr = str.split(',');

split()

just delete the archetype in maven local repository. As said above, it happens in case of failed archetype downloads.

Google Closure Compiler, YUI compressor, Minify, /Packer/... etc, are options for compressing/obfuscating your JS codes. But none of them can help you from hiding your code from the users.

Anyone with decent knowledge can easily decode/de-obfuscate your code using tools like JS Beautifier. You name it.

So the answer is, you can always make your code harder to read/decode, but for sure there is no way to hide.

Problem is system is not able to find the file tools.jar

So first check that the file is there in the JDK installation of the directory.

Make the below entry in POM.xml as rightly pointed by others

<dependency>
<groupId>com.sun</groupId>
<artifactId>tools</artifactId>
<version>1.6</version>
<scope>system</scope>
<systemPath>C:\Program Files\Java\jdk1.8.0_241\lib\tools.jar</systemPath>
</dependency> 

then Follow the below steps also to remove the problem

1) Right Click on your project

2) Click on Build path

As per the below image, select the workspace default JRE and click on finish.

Let's see how your algorithm works:

an array of unique values:

[1, 2, 3]

check 1 == 1. yes, there is duplicate, assigning duplicate to true.
check 1 == 2. no, doing nothing.
check 1 == 3. no, doing nothing.
check 2 == 1. no, doing nothing.
check 2 == 2. yes, there is duplicate, assigning duplicate to true.
check 2 == 3. no, doing nothing.
check 3 == 1. no, doing nothing.
check 3 == 2. no, doing nothing.
check 3 == 3. yes, there is duplicate, assigning duplicate to true.

a better algorithm:

for (j=0;j<zipcodeList.length;j++) {
    for (k=j+1;k<zipcodeList.length;k++) {
        if (zipcodeList[k]==zipcodeList[j]){ // or use .equals()
            return true;
        }
    }
}
return false;

sudo ln -s /usr/bin/nodejs /usr/bin/node

or install legacy nodejs:

sudo apt-get install nodejs-legacy

As seen in this GitHub issue.

Case where [] notation is helpful :

If your object is dynamic and there could be some random values in keys like number and []or any other special character, for example -

var a = { 1 : 3 };

Now if you try to access in like a.1 it will through an error, because it is expecting an string over there.

This will get you the current SHA1 hash

Abbreviated Commit Hash

git show <tag> --format="%h" --> 42e646e

Commit Hash

git show <tag> --format="%H" --> 42e646ea3483e156c58cf68925545fffaf4fb280

I think a nice solution is with the function filter of pandas and regex (match everything except "b"):

df.filter(regex="^(?!b$)")

If you want to allow every bot to crawl everything, this is the best way to specify it in your robots.txt:

User-agent: *
Disallow:

Note that the Disallow field has an empty value, which means according to the specification:

Any empty value, indicates that all URLs can be retrieved.

Your way (with Allow: / instead of Disallow:) works, too, but Allow is not part of the original robots.txt specification, so it’s not supported by all bots (many popular ones support it, though, like the Googlebot). That said, unrecognized fields have to be ignored, and for bots that don’t recognize Allow, the result would be the same in this case anyway: if nothing is forbidden to be crawled (with Disallow), everything is allowed to be crawled.
However, formally (per the original spec) it’s an invalid record, because at least one Disallow field is required:

At least one Disallow field needs to be present in a record.

I've come up with an awkward but functional solution for my problem. It works for a one-dimensional array (more dimensions would be tricky) and input that fits into a varchar:

  declare pos int;           -- Keeping track of the next item's position
  declare item varchar(100); -- A single item of the input
  declare breaker int;       -- Safeguard for while loop 

  -- The string must end with the delimiter
  if right(inputString, 1) <> '|' then
     set inputString = concat(inputString, '|');
  end if;

  DROP TABLE IF EXISTS MyTemporaryTable;
  CREATE TEMPORARY TABLE MyTemporaryTable ( columnName varchar(100) );
  set breaker = 0;

  while (breaker < 2000) && (length(inputString) > 1) do
     -- Iterate looking for the delimiter, add rows to temporary table.
     set breaker = breaker + 1;
     set pos = INSTR(inputString, '|');
     set item = LEFT(inputString, pos - 1);
     set inputString = substring(inputString, pos + 1);
     insert into MyTemporaryTable values(item);
  end while;

For example, input for this code could be the string Apple|Banana|Orange. MyTemporaryTable will be populated with three rows containing the strings Apple, Banana, and Orange respectively.

I thought the slow speed of string handling would render this approach useless, but it was quick enough (only a fraction of a second for a 1,000 entries array).

Hope this helps somebody.

void method(boolean u,int max)
{
    uu=u;
    maxi=max;
    if (uu==true)
    { 
        CountDownTimer uy = new CountDownTimer(maxi, 1000) 
  {
            public void onFinish()
            {
                text.setText("Finish"); 
            }

            @Override
            public void onTick(long l) {
                String currentTimeString=DateFormat.getTimeInstance().format(new Date());
                text.setText(currentTimeString);
            }
        }.start();
    }

    else{text.setText("Stop ");
}

You are correct. Local variables are not allowed in a VIEW.

You can set a local variable in a table valued function, which returns a result set (like a view does.)

http://msdn.microsoft.com/en-us/library/ms191165.aspx

e.g.

CREATE FUNCTION dbo.udf_foo()
RETURNS @ret TABLE (col INT)
AS
BEGIN
  DECLARE @myvar INT;
  SELECT @myvar = 1;
  INSERT INTO @ret SELECT @myvar;
  RETURN;
END;
GO
SELECT * FROM dbo.udf_foo();
GO

You also can send in mutable objects as parameters, if you use methods to modify them then they will be modified when you return from the function. It won't work on stuff like Float, since it is immutable.

public class HelloWorld{

     public static void main(String []args){
        HelloWorld world = new HelloWorld();

        world.run();
     }



    private class Dog
    {
       private String name;
       public void setName(String s)
       {
           name = s;
       }
       public String getName() { return name;}
       public Dog(String name)
       {
           setName(name);
       }
    }

    public void run()
    {
       Dog newDog = new Dog("John");
       nameThatDog(newDog);
       System.out.println(newDog.getName());
     }


     public void nameThatDog(Dog dog)
     {
         dog.setName("Rutger");
     }
}

The result is: Rutger

We have two ways to change default port number in Angular.

First way to cli command:

ng serve --port 2400 --open

Second way is by configuration at the location: ProjectName\node_modules\@angular-devkit\build-angular\src\dev-server\schema.json.

Make changes in schema.json file.

I've tried different ways of blocking scrolling when the arrow keys are pressed, both jQuery and native Javascript - they all work fine in Firefox, but don't work in recent versions of Chrome.
Even the explicit {passive: false} property for window.addEventListener, which is recommended as the only working solution, for example here.

In the end, after many tries, I found a way that works for me in both Firefox and Chrome:

window.addEventListener('keydown', (e) => {
    if (e.target.localName != 'input') {   // if you need to filter <input> elements
        switch (e.keyCode) {
            case 37: // left
            case 39: // right
                e.preventDefault();
                break;
            case 38: // up
            case 40: // down
                e.preventDefault();
                break;
            default:
                break;
        }
    }
}, {
    capture: true,   // this disables arrow key scrolling in modern Chrome
    passive: false   // this is optional, my code works without it
});

Quote for EventTarget.addEventListener() from MDN

options Optional
   An options object specifies characteristics about the event listener. The available options are:

capture
   A Boolean indicating that events of this type will be dispatched to the registered listener before being dispatched to any EventTarget beneath it in the DOM tree.
once
   ...
passive
   A Boolean that, if true, indicates that the function specified by listener will never call preventDefault(). If a passive listener does call preventDefault(), the user agent will do nothing other than generate a console warning. ...

The simplest way to remove duplicates whilst preserving order is to use collections.OrderedDict (Python 2.7+).

from collections import OrderedDict
d = OrderedDict()
for x in mylist:
    d[x] = True
print d.iterkeys()

margin-left: auto works well. But clean flex box solution would be space-between in the main class. Space between works well if there is two or more elements. I have added a solution for single element as well.

.main { display: flex; justify-content: space-between; }
.a, .b, .c { background: #efefef; border: 1px solid #999; padding: 0.25rem; margin: 0.25rem;}
.b { flex: 1; text-align: center; }

.c-wrapper {
  display: flex;
  flex: 1;
  justify-content: flex-end;
}

.c-wrapper2 {
  display: flex;
  flex: 1;
  flex-flow: row-reverse;
}

<div class="main">
    <div class="a"><a href="#">Home</a></div>
    <div class="b"><a href="#">Some title centered</a></div>
    <div class="c"><a href="#">Contact</a></div>
</div>

<div class="main">
    <div class="a"><a href="#">Home</a></div>
    <div class="c"><a href="#">Contact</a></div>
</div>

<div class="main">
    <div class="c-wrapper">
      <a class="c" href="#">Contact</a>
      <a class="c" href="#">Contact2</a>
    </div>
</div>
<div class="main">
    <div class="c-wrapper2">
      <span class="c">Contact</span>
      <span class="c">Contact2</span>
    </div>
</div>

Simple example below. Note you should pass in a larger buffer, and test to see if the buffer was large enough or not

void Log(LPCWSTR pFormat, ...) 
{
    va_list pArg;
    va_start(pArg, pFormat);
    char buf[1000];
    int len = _vsntprintf(buf, 1000, pFormat, pArg);
    va_end(pArg);
    //do something with buf
}

I actually have a similar problem. I have a page with multiple radio buttons; each button will set the title and description meta tags of the page, via JavaScript upon change.

For example, if users select the first button, the meta tags will say:

<meta name="title" content="First Title">
<meta name="description" content="First Description">

If the user select the second button, this changes the meta tags to:

<meta name="title" content="Second Title">
<meta name="description" content="Second Description">

... and so on. I have confirmed that the code is working fine via Firebug (i.e. I can see that those two tags were properly changed).

Apparently, Facebook Share only pulls in the title and description meta tags that are available upon page load. The changes to those two tags post page load are completely ignored.

Does anybody have any ideas on how to solve this? That is, to force Facebook to get the latest values that are change after the page loads.

If you use Windows, you will found it follow this: File-->Project Structure-->Facets

chose your Android project and in the "Facet 'Android'" window click TAB "Packaging",you will found what you want

Even more reliable than @mifmif :

Go to Window Menu > Preferences > General > Appearance > Colors and Fonts

then go to Basic.

This section has about 5 different fonts in it, all of which contain a size. If you go to an item in any other section (like Java > Java Editor Text Font as @mifmif suggested) the Edit Default and Go to Default buttons will be enabled. Clicking the latter takes you to the corresponding item in the Basic section. Clicking the former lets you edit that item directly.

Changing the Basic font items will handle not only Java text but just about every other text in Eclipse that can be resized, as far as I can tell.

I eventually shut-down and restarted Microsoft SQL Server Management Studio; and that fixed it for me. But at other times, just starting a new query window was enough.

void transfer(double x) {
unsigned long long* p = (unsigned long long*)&x;
for (int i = sizeof(unsigned long long) * 8 - 1; i >= 0; i--) {cout<< ((*p) >>i & 1);}}

I am not sure but as per my knowledge I share my views. I always accept best answer if I am wrong .

Alarm Manager

The Alarm Manager holds a CPU wake lock as long as the alarm receiver's onReceive() method is executing. This guarantees that the phone will not sleep until you have finished handling the broadcast. Once onReceive() returns, the Alarm Manager releases this wake lock. This means that the phone will in some cases sleep as soon as your onReceive() method completes. If your alarm receiver called Context.startService(), it is possible that the phone will sleep before the requested service is launched. To prevent this, your BroadcastReceiver and Service will need to implement a separate wake lock policy to ensure that the phone continues running until the service becomes available.

Note: The Alarm Manager is intended for cases where you want to have your application code run at a specific time, even if your application is not currently running. For normal timing operations (ticks, timeouts, etc) it is easier and much more efficient to use Handler.

Timer

timer = new Timer();

    timer.scheduleAtFixedRate(new TimerTask() {

        synchronized public void run() {

            \\ here your todo;
            }

        }, TimeUnit.MINUTES.toMillis(1), TimeUnit.MINUTES.toMillis(1));

Timer has some drawbacks that are solved by ScheduledThreadPoolExecutor. So it's not the best choice

ScheduledThreadPoolExecutor.

You can use java.util.Timer or ScheduledThreadPoolExecutor (preferred) to schedule an action to occur at regular intervals on a background thread.

Here is a sample using the latter:

ScheduledExecutorService scheduler =
    Executors.newSingleThreadScheduledExecutor();

scheduler.scheduleAtFixedRate
      (new Runnable() {
         public void run() {
            // call service
         }
      }, 0, 10, TimeUnit.MINUTES);

So I preferred ScheduledExecutorService

But Also think about that if the updates will occur while your application is running, you can use a Timer, as suggested in other answers, or the newer ScheduledThreadPoolExecutor. If your application will update even when it is not running, you should go with the AlarmManager.

The Alarm Manager is intended for cases where you want to have your application code run at a specific time, even if your application is not currently running.

Take note that if you plan on updating when your application is turned off, once every ten minutes is quite frequent, and thus possibly a bit too power consuming.

One more solution:

#footer { display:table; margin:0 auto; }
#footer li { display:table-cell; padding: 0px 10px; }

Then ul doesn't jump to the next line in case of zooming text.

The .bashrc file is used for setting variables used by interactive login shells. If you want those environment variables available in Eclipse you need to put them in /etc/environment.

If you don't "care" about the data you can just do something like:

search_params = params[:search].valid_encoding? ? params[:search].gsub(/\W+/, '') : "nothing"

I just used valid_encoding? to get passed it. Mine is a search field, and so i was finding the same weirdness over and over so I used something like: just to have the system not break. Since i don't control the user experience to autovalidate prior to sending this info (like auto feedback to say "dummy up!") I can just take it in, strip it out and return blank results.

Another alternative:

Use the code from the unicodecsv package ...

https://pypi.python.org/pypi/unicodecsv/

>>> import unicodecsv as csv
>>> from io import BytesIO
>>> f = BytesIO()
>>> w = csv.writer(f, encoding='utf-8')
>>> _ = w.writerow((u'é', u'ñ'))
>>> _ = f.seek(0)
>>> r = csv.reader(f, encoding='utf-8')
>>> next(r) == [u'é', u'ñ']
True

This module is API compatible with the STDLIB csv module.

Netbeans 8.0 (beta at the time of this post) has Angular support as well as HTML5 support.

Thanx to @Jota.Toledo, I got the solution for my table creation. Please find the working code below:

component.html

<mat-table #table [dataSource]="dataSource" matSort>
  <ng-container matColumnDef="{{column.id}}" *ngFor="let column of columnNames">
    <mat-header-cell *matHeaderCellDef mat-sort-header> {{column.value}}</mat-header-cell>
    <mat-cell *matCellDef="let element"> {{element[column.id]}}</mat-cell>
  </ng-container>

  <mat-header-row *matHeaderRowDef="displayedColumns"></mat-header-row>
  <mat-row *matRowDef="let row; columns: displayedColumns;"></mat-row>
</mat-table>

component.ts

import { Component, OnInit, ViewChild } from '@angular/core';
import { MatTableDataSource, MatSort } from '@angular/material';
import { DataSource } from '@angular/cdk/table';

@Component({
  selector: 'app-m',
  templateUrl: './m.component.html',
  styleUrls: ['./m.component.css'],
})
export class MComponent implements OnInit {

  dataSource;
  displayedColumns = [];
  @ViewChild(MatSort) sort: MatSort;

  /**
   * Pre-defined columns list for user table
   */
  columnNames = [{
    id: 'position',
    value: 'No.',

  }, {
    id: 'name',
    value: 'Name',
  },
    {
      id: 'weight',
      value: 'Weight',
    },
    {
      id: 'symbol',
      value: 'Symbol',
    }];

  ngOnInit() {
    this.displayedColumns = this.columnNames.map(x => x.id);
    this.createTable();
  }

  createTable() {
    let tableArr: Element[] = [{ position: 1, name: 'Hydrogen', weight: 1.0079, symbol: 'H' },
      { position: 2, name: 'Helium', weight: 4.0026, symbol: 'He' },

    this.dataSource = new MatTableDataSource(tableArr);
    this.dataSource.sort = this.sort;
  }
}

export interface Element {
  position: number,
  name: string,
  weight: number,
  symbol: string
}

You need to use reflection to get the method to start with, then "construct" it by supplying type arguments with MakeGenericMethod:

MethodInfo method = typeof(Sample).GetMethod(nameof(Sample.GenericMethod));
MethodInfo generic = method.MakeGenericMethod(myType);
generic.Invoke(this, null);

For a static method, pass null as the first argument to Invoke. That's nothing to do with generic methods - it's just normal reflection.

As noted, a lot of this is simpler as of C# 4 using dynamic - if you can use type inference, of course. It doesn't help in cases where type inference isn't available, such as the exact example in the question.

If you did literally this:

encodeURIComponent('&')

Then the result is %26, you can test it here. Make sure the string you are encoding is just & and not & to begin with...otherwise it is encoding correctly, which is likely the case. If you need a different result for some reason, you can do a .replace(/&/g,'&') before the encoding.

Lazy Set

VARIABLE = value

Normal setting of a variable, but any other variables mentioned with the value field are recursively expanded with their value at the point at which the variable is used, not the one it had when it was declared

Immediate Set

VARIABLE := value

Setting of a variable with simple expansion of the values inside - values within it are expanded at declaration time.

Lazy Set If Absent

VARIABLE ?= value

Setting of a variable only if it doesn't have a value. value is always evaluated when VARIABLE is accessed. It is equivalent to

ifeq ($(origin FOO), undefined)
  FOO = bar
endif

See the documentation for more details.

Append

VARIABLE += value

Appending the supplied value to the existing value (or setting to that value if the variable didn't exist)

Or use JodaTime:

DateTime lastWeek = new DateTime().minusDays(7);

Add this to the top of your file and the site will refresh every 30 seconds.

<script type="text/javascript">
    window.onload = Refresh;

    function Refresh() {
        setTimeout("refreshPage();", 30000);
    }
    function refreshPage() {
        window.location = location.href;
    }
</script>

Another one is: Add in the head tag

<meta http-equiv="refresh" content="30">

Will it warn you if you pass a 32-bit unsigned integer to a %lu format? It should be fine since the conversion is well-defined and doesn't lose any information.

I've heard that some platforms define macros in <inttypes.h> that you can insert into the format string literal but I don't see that header on my Windows C++ compiler, which implies it may not be cross-platform.

print my_string[0:100]

you can save them into a $_SESSION variable and then when the user calls that page again populate all the inputs with their respective session variables.

Using this,

        String s = "03/24/2013 21:54";
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("MM/dd/yyyy HH:mm");
        try
        {
            Date date = simpleDateFormat.parse(s);

            System.out.println("date : "+simpleDateFormat.format(date));
        }
        catch (ParseException ex)
        {
            System.out.println("Exception "+ex);
        }

Try this code :-

SELECT *
   FROM one one1
   WHERE ( n ) = ( SELECT COUNT( one2.salary )
                   FROM one one2
                   WHERE one2.salary >= one1.salary
                 )

Okay a lot has been said, but just in case nothing of the previous answers work, you can try;

https://www.scipy.org/install.html

According to them;

For most users, especially on Windows, the easiest way to install the packages of the SciPy stack is to download one of these Python distributions, which include all the key packages:

• Anacond: A free distribution for the SciPy stack. Supports Linux, Windows and Mac.
• Enthought Canopy: The free and commercial versions include the core SciPy stack packages. Supports Linux, Windows and Mac.
• Python(x,y) A free distribution including the SciPy stack, based around the Spyder IDE. Windows only.
• WinPython: A free distribution including the SciPy stack. Windows only.
• Pyzo: A free distribution based on Anaconda and the IEP interactive development environment. Supports Linux, Windows and Mac.

Still for me, Anaconda did solve this problem. Do remember to check the bit (32/64 bit) version before downloading and re-adjust your compiler to the Python implementation installed with the Python distribution you are installing.

1. Log in to your github account.
2. Go to the "Settings" page (the "wrench and screwdriver" icon in the top right corner of the page).
3. Go to "SSH keys" page.
4. Generate a new SSH key (probably studying the links provided by github on that page).
5. Add your new key using the "Add SSH key" link.
6. Verify your new key works.
7. Make gitub forget your old key by using the "Delete" link next to it in the list of known keys.

var iframe = $('iframe'); // or some other selector to get the iframe
$('[tokenid=' + token + ']', iframe.contents()).addClass('border');

Also note that if the src of this iframe is pointing to a different domain, due to security reasons, you will not be able to access the contents of this iframe in javascript.

Solution-1: - If you want to search for a combination of characters or an independent word from a sentence.

String sentence = "In the Name of Allah, the Most Beneficent, the Most Merciful."
if (sentence.matches(".*Beneficent.*")) {return true;}
else{return false;}

Solution-2: - There is another possibility you want to search for an independent word from a sentence then Solution-1 will also return true if you searched a word exists in any other word. For example, If you will search cent from a sentence containing this word ** Beneficent** then Solution-1 will return true. For this remember to add space in your regular expression.

String sentence = "In the Name of Allah, the Most Beneficent, the Most Merciful."
if (sentence.matches(".* cent .*")) {return true;}
else{return false;}

Now in Solution-2 it wll return false because no independent cent word exist.

Additional: You can add or remove space on either side in 2nd solution according to your requirements.

This will work, use the following code in .htaccess file RewriteEngine On

# Send would-be 404 requests to Craft
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !^/(favicon\.ico|apple-touch-icon.*\.png)$ [NC]
RewriteRule (.+) index.php?p=$1 [QSA,L]

You could iterate on a copy (clone) of your original list:

List<String> copy = new ArrayList<String>(list);
for (String s : copy) {
    // And if you have to add an element to the list, add it to the original one:
    list.add("some element");
}

Note that it is not even possible to add a new element to a list while iterating on it, because it will result in a ConcurrentModificationException.

Attach your variable to the req object, not res.

Instead of

res.somevariable = variable1;

Have:

req.somevariable = variable1;

As others have pointed out, res.locals is the recommended way of passing data through middleware.

For some reason classLoader.getResource() always returned null when I deployed the web application to WildFly 14. getting classLoader from getClass().getClassLoader() or Thread.currentThread().getContextClassLoader() returns null.

getClass().getClassLoader() API doc says,

"Returns the class loader for the class. Some implementations may use null to represent the bootstrap class loader. This method will return null in such implementations if this class was loaded by the bootstrap class loader."

may be if you are using WildFly and yours web application try this

request.getServletContext().getResource() returned the resource url. Here request is an object of ServletRequest.

Did you check for DataReaders that are not closed and response.redirects before closing the connection or a datareader. Connections stay open when you dont close them before a redirect.

I ran into the same problem.

I downloaded the 'popper.min.js' file from the CDN on the bootstrap website.

Use a javascript constructor with a callback that fires when the image has finished loading in the background. Just used it and works great for me cross-browser. Here's the thread with the answer.

You can use

git log -g branchname

to see git reflog information formatted like the git log output

"Everything should be made as simple as possible, but not simpler." - Einstein.

Two ways:

1. Implement ActionListener in your class, then use jBtnSelection.addActionListener(this); Later, you'll have to define a menthod, public void actionPerformed(ActionEvent e). However, doing this for multiple buttons can be confusing, because the actionPerformed method will have to check the source of each event (e.getSource()) to see which button it came from.

2. Use anonymous inner classes:

jBtnSelection.addActionListener(new ActionListener() { 
  public void actionPerformed(ActionEvent e) { 
    selectionButtonPressed();
  } 
} );

Later, you'll have to define selectionButtonPressed(). This works better when you have multiple buttons, because your calls to individual methods for handling the actions are right next to the definition of the button.

The second method also allows you to call the selection method directly. In this case, you could call selectionButtonPressed() if some other action happens, too - like, when a timer goes off or something (but in this case, your method would be named something different, maybe selectionChanged()).

The solution, as Dennis Smolek said, is dead simple. Set window.location.href to the URL you want to switch to and it just works.

For example, if you had this method in your component's class file (controller):

goCNN() {
    window.location.href='http://www.cnn.com/';
}

Then you could call it quite simply with the appropriate (click) call on a button (or whatever) in your template:

<button (click)="goCNN()">Go to CNN</button>

As mentioned in other answers Node JS currently doesn't support ES6 imports.

(As of now, read EDIT 2)

Enable ES6 imports in node js provides a solution to this issue. I have tried this and it worked for me.

Run the command:

    npm install babel-register babel-preset-env --save-dev

Now you need to create a new file (config.js) and add the following code to it.

    require('babel-register')({
        presets: [ 'env' ]
    })
    // Import the rest of our application.
    module.exports = require('./your_server_file.js')

Now you can write import statements without getting any errors.

Hope this helps.

EDIT:

You need to run the new file which you created with above code. In my case it was config.js. So I have to run:

    node config.js

EDIT 2:

While experimenting, I found one easy solution to this issue.

Create .babelrc file in the root of your project.

Add following (and any other babel presets you need, can be added in this file):

    {
        "presets": ["env"]
    }

Install babel-preset-env using command npm install babel-preset-env --save, and then install babel-cli using command npm install babel-cli -g --save

Now, go to the folder where your server or index file exists and run using: babel-node fileName.js

Or you can run using npm start by adding following code to your package.json file:

    "scripts": {
        "start": "babel-node src/index.js"
    }

A Web Reference allows you to communicate with any service based on any technology that implements the WS-I Basic Profile 1.1, and exposes the relevant metadata as WSDL. Internally, it uses the ASMX communication stack on the client's side.

A Service Reference allows you to communicate with any service based on any technology that implements any of the many protocols supported by WCF (including but not limited to WS-I Basic Profile). Internally, it uses the WCF communication stack on the client side.

Note that both these definitions are quite wide, and both include services not written in .NET.

It is perfectly possible (though not recommended) to add a Web Reference that points to a WCF service, as long as the WCF endpoint uses basicHttpBinding or some compatible custom variant.

It is also possible to add a Service Reference that points to an ASMX service. When writing new code, you should always use a Service Reference simply because it is more flexible and future-proof.

JObjects can be enumerated via JProperty objects by casting it to a JToken:

foreach (JProperty x in (JToken)obj) { // if 'obj' is a JObject
    string name = x.Name;
    JToken value = x.Value;
}

If you have a nested JObject inside of another JObject, you don't need to cast because the accessor will return a JToken:

foreach (JProperty x in obj["otherObject"]) { // Where 'obj' and 'obj["otherObject"]' are both JObjects
    string name = x.Name;
    JToken value = x.Value;
}

Stopwatch with cumulative cycles

Works with server and client (Node or DOM), uses the Performance API. Good when you have many small cycles e.g. in a function called 1000 times that processes 1000 data objects but you want to see how each operation in this function adds up to the total.

So this one uses a module global (singleton) timer. Same as a class singleton pattern, just a bit simpler to use, but you need to put this in a separate e.g. stopwatch.js file.

const perf = typeof performance !== "undefined" ? performance : require('perf_hooks').performance;
const DIGITS = 2;

let _timers = {};

const _log = (label, delta?) => {
    if (_timers[label]) {
        console.log(`${label}: ` + (delta ? `${delta.toFixed(DIGITS)} ms last, ` : '') +
            `${_timers[label].total.toFixed(DIGITS)} ms total, ${_timers[label].cycles} cycles`);
    }
};

export const Stopwatch = {
    start(label) {
        const now = perf.now();
        if (_timers[label]) {
            if (!_timers[label].started) {
                _timers[label].started = now;
            }
        } else {
            _timers[label] = {
                started: now,
                total: 0,
                cycles: 0
            };
        }
    },
    /** Returns total elapsed milliseconds, or null if stopwatch doesn't exist. */
    stop(label, log = false) {
        const now = perf.now();
        if (_timers[label]) {
            let delta;
            if(_timers[label].started) {
                delta = now - _timers[label].started;
                _timers[label].started = null;
                _timers[label].total += delta;
                _timers[label].cycles++;
            }
            log && _log(label, delta);
            return _timers[label].total;
        } else {
            return null;
        }
    },
    /** Logs total time */
    log: _log,
    delete(label) {
        delete _timers[label];
    }
};

Unfortunately the previous answers were no option for me so i researched for a while and found this solution:

http://blog.alessio.marchetti.name/post/2011/02/12/the-Oliver-Becker-s-XPath-method

I use it to output text if a certain Node exists. 4 is the length of the text foo. So i guess a more elegant solution would be the use of a variable.

substring('foo',number(not(normalize-space(/elements/the/element/)))*4)

You can use in Content-security-policy add "img-src 'self' data:;" And Use outline CSS.Don't use Inline CSS.It's secure from attackers.

Or this:

$(document).ready(function(){
    $(".header").click(function(){
        $(this).children(".children").toggle();
    });
   $(".header a").click(function(e) {
        return false;
   });
});

I used Rafid's suggestion of using AJAX.

This worked for me:

var url = "http://www.example.com/file.json";

var jsonFile = new XMLHttpRequest();
    jsonFile.open("GET",url,true);
    jsonFile.send();

    jsonFile.onreadystatechange = function() {
        if (jsonFile.readyState== 4 && jsonFile.status == 200) {
            document.getElementById("id-of-element").innerHTML = jsonFile.responseText;
        }
     }

I basically(almost literally) copied this code from http://www.w3schools.com/ajax/tryit.asp?filename=tryajax_get2 so credit to them for everything.

I dont have much knowledge of how this works but you don't have to know how your brakes work to use them ;)

Hope this helps!

You can also use either the spring utils, or load properties via the PropertiesFactoryBean.

<util:properties id="myProps" location="classpath:com/foo/myprops.properties"/>

or:

<bean id="myProps" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
  <property name="location" value="classpath:com/foo/myprops.properties"/>
</bean>

Then you can pick them up in your application with:

@Resource(name = "myProps")
private Properties myProps;

and additionally use these properties in your config:

<context:property-placeholder properties-ref="myProps"/>

This is also in the docs: http://docs.spring.io/spring/docs/current/spring-framework-reference/htmlsingle/#xsd-config-body-schemas-util-properties

maybe not as stylish, but easier:

#!/bin/bash
log="/var/log/yourlog"
/path/to/your/script.py 2>&1 | (while read; do echo "$REPLY" >> $log; done)

String start_dt = "2011-01-31";

DateFormat parser = new SimpleDateFormat("yyyy-MM-dd"); 
Date date = (Date) parser.parse(start_dt);

DateFormat formatter = new SimpleDateFormat("MM-dd-yyyy"); 
System.out.println(formatter.format(date));

Prints: 01-31-2011

My favorite way is:

df = df[0:0] 

The way you are performing the injection of the property will not work, because the injection is done after the constructor is called.

You need to do one of the following:

Better solution

@Component
public class MyBean {

    private final String prop;

    @Autowired
    public MyBean(@Value("${some.prop}") String prop) {
        this.prop = prop;
        System.out.println("================== " + prop + "================== ");
    }
}

Solution that will work but is less testable and slightly less readable

@Component
public class MyBean {

    @Value("${some.prop}")
    private String prop;

    public MyBean() {

    }

    @PostConstruct
    public void init() {
        System.out.println("================== " + prop + "================== ");
    }
}

Also note that is not Spring Boot specific but applies to any Spring application

If you're running your PHP script from the command-line, passthru() has one large benefit. It will let you execute scripts/programs such as vim, dialog, etc, letting those programs handle control and returning to your script only when they are done.

If you use system() or exec() to execute those scripts/programs, it simply won't work.

Gotcha: For some reason, you can't execute less with passthru() in PHP.

This might sound like a really basic "DUH" answer, but make sure that the column you're using to Lookup from on the merging file is actually full of unique values!

I noticed earlier today that PowerQuery won't throw you an error (like in PowerPivot) and will happily allow you to run a Many-Many merge. This will result in multiple rows being produced for each record that matches with a non-unique value.

I needed to do something similar and came across the same issues. I used the AfterSelect event to make sure I wasn't getting the previously selected node.

It's actually really easy to reference the correct node to receive the new child node.

private void TreeView1_AfterSelect(object sender, System.Windows.Forms.TreeViewEventArgs e)
{
   //show dialogbox to let user name the new node
   frmDialogInput f = new frmDialogInput();
   f.ShowDialog();

    //find the node that was selected
    TreeNode myNode = TreeView1.SelectedNode;
    //create the new node to add
    TreeNode newNode = new TreeNode(f.EnteredText);
    //add the new child to the selected node
    myNode.Nodes.Add(newNode);
}

<properties>
    <maven.test.skip>true</maven.test.skip>
</properties>

is also a way to add in pom file

A single line method within bash works like this.

[some out put] >$(date "+%Y.%m.%d-%H.%M.%S").ver

will create a file with a timestamp name with ver extension. A working file listing snap shot to a date stamp file name as follows can show it working.

find . -type f -exec ls -la {} \; | cut -d ' ' -f 6- >$(date "+%Y.%m.%d-%H.%M.%S").ver

Of course

cat somefile.log > $(date "+%Y.%m.%d-%H.%M.%S").ver

or even simpler

ls > $(date "+%Y.%m.%d-%H.%M.%S").ver
