Wow...there is a lot of low-level security code in this thread -- most of which did not work for me, either -- although I learned a lot in the process. One thing that I learned is that most of this code is not geared to applications seeking per user access rights -- it is for Administrators wanting to alter rights programmatically, which -- as has been pointed out -- is not a good thing. As a developer, I cannot use the "easy way out" -- by running as Administrator -- which -- I am not one on the machine that runs the code, nor are my users -- so, as clever as these solutions are -- they are not for my situation, and probably not for most rank and file developers, either.

Like most posters of this type of question -- I initially felt it was "hackey", too -- I have since decided that it is perfectly alright to try it and let the possible exception tell you exactly what the user's rights are -- because the information I got did not tell me what the rights actually were. The code below -- did.

  Private Function CheckUserAccessLevel(folder As String) As Boolean
Try
  Dim newDir As String = String.Format("{0}{1}{2}",
                                       folder,
                                       If(folder.EndsWith("\"),
                                          "",
                                          "\"),
                                       "LookWhatICanDo")
  Dim lookWhatICanDo = Directory.CreateDirectory(newDir)

  Directory.Delete(newDir)
  Return True

Catch ex As Exception
  Return False
End Try

End Function

A more idiomatic approach would be to use Array.prototype.reduce:

var arr = [_x000D_
  [ 'cardType', 'iDEBIT' ],_x000D_
  [ 'txnAmount', '17.64' ],_x000D_
  [ 'txnId', '20181' ],_x000D_
  [ 'txnType', 'Purchase' ],_x000D_
  [ 'txnDate', '2015/08/13 21:50:04' ],_x000D_
  [ 'respCode', '0' ],_x000D_
  [ 'isoCode', '0' ],_x000D_
  [ 'authCode', '' ],_x000D_
  [ 'acquirerInvoice', '0' ],_x000D_
  [ 'message', '' ],_x000D_
  [ 'isComplete', 'true' ],_x000D_
  [ 'isTimeout', 'false' ]_x000D_
];_x000D_
_x000D_
var obj = arr.reduce(function (o, currentArray) {_x000D_
  var key = currentArray[0], value = currentArray[1]_x000D_
  o[key] = value_x000D_
  return o_x000D_
}, {})_x000D_
_x000D_
console.log(obj)_x000D_
document.write(JSON.stringify(obj).split(',').join(',<br>'))

This is more visually appealing, when done with ES6 (rest parameters) syntax:

let obj = arr.reduce((o, [ key, value ]) => {
    o[key] = value
    return o
}, {})

this is my sample you can use:

        public static string GetFileNameValidChar(string fileName)
    {
        foreach (var item in System.IO.Path.GetInvalidFileNameChars())
        {
            fileName = fileName.Replace(item.ToString(), "");
        }
        return fileName;
    }

    public static string GetFileNameFromUrl(string url)
    {
        string fileName = "";
        if (Uri.TryCreate(url, UriKind.Absolute, out Uri uri))
        {
            fileName = GetFileNameValidChar(Path.GetFileName(uri.AbsolutePath));
        }
        string ext = "";
        if (!string.IsNullOrEmpty(fileName))
        {
            ext = Path.GetExtension(fileName);
            if (string.IsNullOrEmpty(ext))
                ext = ".html";
            else
                ext = "";
            return GetFileNameValidChar(fileName + ext);

        }

        fileName = Path.GetFileName(url);
        if (string.IsNullOrEmpty(fileName))
        {
            fileName = "noName";
        }
        ext = Path.GetExtension(fileName);
        if (string.IsNullOrEmpty(ext))
            ext = ".html";
        else
            ext = "";
        fileName = fileName + ext;
        if (!fileName.StartsWith("?"))
            fileName = fileName.Split('?').FirstOrDefault();
        fileName = fileName.Split('&').LastOrDefault().Split('=').LastOrDefault();
        return GetFileNameValidChar(fileName);
    }

Usage:

var fileName = GetFileNameFromUrl("http://cdn.p30download.com/?b=p30dl-software&f=Mozilla.Firefox.v58.0.x86_p30download.com.zip");

I just want to build upon Serpens answer and add the line:

logger.setLevel('DEBUG')

This will allow you to chose what level of message gets logged.

For example in Serpens example,

logger.info('Info message')

Will not get recorded as it defaults to only recording Warnings and above.

More about levels used can be read about here

You can import the module and check the module.__file__ string. It contains the path to the associated source file.

Alternatively, you can read the File tag in the the module documentation, which can be accessed using help(module), or module? in IPython.

Well, one way is to compile it as x64 with VS2008

This runs as you would expect:

int normalInt = 5; 
unsigned long long int num=285212672;
printf(
    "My number is %d bytes wide and its value is %ul. 
    A normal number is %d \n", 
    sizeof(num), 
    num, 
    normalInt);

For 32 bit code, we need to use the correct __int64 format specifier %I64u. So it becomes.

int normalInt = 5; 
unsigned __int64 num=285212672;
printf(
    "My number is %d bytes wide and its value is %I64u. 
    A normal number is %d", 
    sizeof(num),
    num, normalInt);

This code works for both 32 and 64 bit VS compiler.

Two things you have to do.

Install development package for Python, in case of Debian/Ubuntu/Mint it's done with command:

sudo apt-get install python-dev

Second thing is that include files are not by default in the include path, nor is Python library linked with executable by default. You need to add these flags (replace Python's version accordingly):

-I/usr/include/python2.7 -lpython2.7 

In other words your compile command ought to be:

gcc -Wall -I/usr/include/python2.7 -lpython2.7  utilsmodule.c -o Utilc 

I wanted to build a string from a list. Couldn't find an answer for that so I post it here. Here is what I did:

list=(1 2 3 4 5)
string=''

for elm in "${list[@]}"; do
    string="${string} ${elm}"
done

echo ${string}

and then I get the following output:

1 2 3 4 5

You can also get the WINDOW width and height, avoiding browser toolbars and... (not just screen size).

To do this, use: window.innerWidth and window.innerHeight properties. See it at w3schools.

In most cases it will be the best way, in example, to display a perfectly centred floating modal dialog. It allows you to calculate positions on window, no matter which resolution orientation or window size is using the browser.

Missing a semicolon

if [ -a myApp ];
then
  rm myApp
fi

However, I assume you are checking for existence before deletion to prevent an error message. If so, you can just use rm -f myApp which "forces" delete, i.e. doesn't error out if the file didn't exist.

you can use below code to check for brokers available if server is running.

import org.I0Itec.zkclient.ZkClient;
     public static boolean isBrokerRunning(){
        boolean flag = false;
        ZkClient zkClient = new ZkClient(endpoint.getZookeeperConnect(), 10000);//, kafka.utils.ZKStringSerializer$.MODULE$);
        if(zkClient!=null){
            int brokersCount = zkClient.countChildren(ZkUtils.BrokerIdsPath());
            if(brokersCount > 0){
                logger.info("Following Broker(s) {} is/are available on Zookeeper.",zkClient.getChildren(ZkUtils.BrokerIdsPath()));
                flag = true;    
            }
            else{
                logger.error("ERROR:No Broker is available on Zookeeper.");
            }
            zkClient.close();

        }
        return flag;
    }

pretty sure you just want the plain old replace function. use like this:

myString.replace('username1','');

i suppose if you want to remove the trailing comma do this instead:

myString.replace('username1,','');

edit:

here is your site specific code:

jQuery("#post_like_list-510").text().replace(...) 

foreach ($tmpArray as $innerArray) {
    //  Check type
    if (is_array($innerArray)){
        //  Scan through inner loop
        foreach ($innerArray as $value) {
            echo $value;
        }
    }else{
        // one, two, three
        echo $innerArray;
    }
}

Annotation-driven indicates to Spring that it should scan for annotated beans, and to not just rely on XML bean configuration. Component-scan indicates where to look for those beans.

Here's some doc: http://static.springsource.org/spring/docs/current/spring-framework-reference/html/mvc.html#mvc-config-enable

Corrected as of 25.06.2019:

var newDate = new Date(date.setMonth(date.getMonth()+8));

Old From here:

var jan312009 = new Date(2009, 0, 31);
var eightMonthsFromJan312009  = jan312009.setMonth(jan312009.getMonth()+8);

Classic example:

window.foo = 'bar';

A modern, safe example following best practice by using an IIFE:

;(function (root) {
    'use strict'

    root.foo = 'bar';
)(this));

Nowadays, there's also the option of using the WebStorage API:

localStorage.foo = 42;

or

sessionStorage.bar = 21;

Performance-wise, I'm not sure whether it is noticeably slower than storing values in variables.

Widespread browser support as stated on Can I use....

Here is another solution I wrote in C# to auto startup native node server or pm2 server on Windows.

I suggest qTip.

Try

this.router.navigate([], { 
  queryParams: {
    query: value
  }
});

will work for same route navigation other than single quotes.

This is a recurring subject in Stackoverflow and since I was unable to find a relevant implementation I decided to accept the challenge.

I made some modifications to the squares demo present in OpenCV and the resulting C++ code below is able to detect a sheet of paper in the image:

void find_squares(Mat& image, vector<vector<Point> >& squares)
{
    // blur will enhance edge detection
    Mat blurred(image);
    medianBlur(image, blurred, 9);

    Mat gray0(blurred.size(), CV_8U), gray;
    vector<vector<Point> > contours;

    // find squares in every color plane of the image
    for (int c = 0; c < 3; c++)
    {
        int ch[] = {c, 0};
        mixChannels(&blurred, 1, &gray0, 1, ch, 1);

        // try several threshold levels
        const int threshold_level = 2;
        for (int l = 0; l < threshold_level; l++)
        {
            // Use Canny instead of zero threshold level!
            // Canny helps to catch squares with gradient shading
            if (l == 0)
            {
                Canny(gray0, gray, 10, 20, 3); // 

                // Dilate helps to remove potential holes between edge segments
                dilate(gray, gray, Mat(), Point(-1,-1));
            }
            else
            {
                    gray = gray0 >= (l+1) * 255 / threshold_level;
            }

            // Find contours and store them in a list
            findContours(gray, contours, CV_RETR_LIST, CV_CHAIN_APPROX_SIMPLE);

            // Test contours
            vector<Point> approx;
            for (size_t i = 0; i < contours.size(); i++)
            {
                    // approximate contour with accuracy proportional
                    // to the contour perimeter
                    approxPolyDP(Mat(contours[i]), approx, arcLength(Mat(contours[i]), true)*0.02, true);

                    // Note: absolute value of an area is used because
                    // area may be positive or negative - in accordance with the
                    // contour orientation
                    if (approx.size() == 4 &&
                            fabs(contourArea(Mat(approx))) > 1000 &&
                            isContourConvex(Mat(approx)))
                    {
                            double maxCosine = 0;

                            for (int j = 2; j < 5; j++)
                            {
                                    double cosine = fabs(angle(approx[j%4], approx[j-2], approx[j-1]));
                                    maxCosine = MAX(maxCosine, cosine);
                            }

                            if (maxCosine < 0.3)
                                    squares.push_back(approx);
                    }
            }
        }
    }
}

After this procedure is executed, the sheet of paper will be the largest square in vector<vector<Point> >:

I'm letting you write the function to find the largest square. ;)

alter table Employee alter column salary numeric(22,5)

You need only this:

android:autoLink="web"

Insert this line to TextView, that can be clickable with reference to the web. URL address set as a text of this TextView.

Example:

 <TextView
    android:id="@+id/textViewWikiURL"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="20sp"
    android:textStyle="bold"
    android:text="http://www.wikipedia.org/"
    android:autoLink="web" />

You dont have to

RUN mkdir -p /usr/src/app

This will be created automatically when you specifiy your WORKDIR

FROM node:latest
WORKDIR /usr/src/app
COPY package.json .
RUN npm install
COPY . ./
EXPOSE 3000
CMD [ “npm”, “start” ] 

According to the HTML5 CR, which requires continued support to “obsolete” features, too, the align=center attribute is rather tricky. Rendering rules for tables say: td elements with that attribute “are expected to center text within themselves, as if they had their 'text-align' property set to 'center' in a presentational hint, and to align descendants to the center.”

And aligning descendants is defined as so that a browser will “align only those descendants that have both their 'margin-left' and 'margin-right' properties computing to a value other than 'auto', that are over-constrained and that have one of those two margins with a used value forced to a greater value, and that do not themselves have an applicable align attribute. When multiple elements are to align a particular descendant, the most deeply nested such element is expected to override the others. Aligned elements are expected to be aligned by having the used values of their left and right margins be set accordingly.”

So it really depends on the content.

Two things. First, you must base64 decode the mykey.pem file yourself. Second, the openssl private key format is specified in PKCS#1 as the RSAPrivateKey ASN.1 structure. It is not compatible with java's PKCS8EncodedKeySpec, which is based on the SubjectPublicKeyInfo ASN.1 structure. If you are willing to use the bouncycastle library you can use a few classes in the bouncycastle provider and bouncycastle PKIX libraries to make quick work of this.

import java.io.BufferedReader;
import java.io.FileReader;
import java.security.KeyPair;
import java.security.Security;

import org.bouncycastle.jce.provider.BouncyCastleProvider;
import org.bouncycastle.openssl.PEMKeyPair;
import org.bouncycastle.openssl.PEMParser;
import org.bouncycastle.openssl.jcajce.JcaPEMKeyConverter;

// ...   

String keyPath = "mykey.pem";
BufferedReader br = new BufferedReader(new FileReader(keyPath));
Security.addProvider(new BouncyCastleProvider());
PEMParser pp = new PEMParser(br);
PEMKeyPair pemKeyPair = (PEMKeyPair) pp.readObject();
KeyPair kp = new JcaPEMKeyConverter().getKeyPair(pemKeyPair);
pp.close();
samlResponse.sign(Signature.getInstance("SHA1withRSA").toString(), kp.getPrivate(), certs);

Your if statements are checking for int values. raw_input returns a string. Change the following line:

Use alter session set current_schema = <username>, in your case as an execute immediate.

See Oracle's documentation for further information.

In your case, that would probably boil down to (untested)

DECLARE

   CURSOR client_cur IS
     SELECT  distinct username 
       from all_users 
      where length(username) = 3;

   -- client cursor 
   CURSOR emails_cur IS
   SELECT id, name 
     FROM org;

BEGIN

   FOR client IN client_cur LOOP

   -- ****
      execute immediate 
     'alter session set current_schema = ' || client.username;
   -- ****

      FOR email_rec in client_cur LOOP

         dbms_output.put_line(
             'Org id is ' || email_rec.id || 
             ' org nam '  || email_rec.name);

      END LOOP;

  END LOOP;
END;

You repository is bare, i.e. it does not have a working tree attached to it. You can clone it locally to create a working tree for it, or you could use one of several other options to tell Git where the working tree is, e.g. the --work-tree option for single commands, or the GIT_WORK_TREE environment variable. There is also the core.worktree configuration option but it will not work in a bare repository (check the man page for what it does).

# git --work-tree=/path/to/work/tree checkout master
# GIT_WORK_TREE=/path/to/work/tree git status

You can try this code:

/**code starts here**/

a.class_name { display : block;text-align : center; }

I had a similar problem and the solution was in the right use of the '$' (end-of-string) character:

My main url.py looked like this (notice the $ character):

urlpatterns = [
url(r'^admin/', include(admin.site.urls )),
url(r'^$', include('card_purchase.urls' )),
]

and my url.py for my card_purchases app said:

urlpatterns = [
url(r'^$', views.index, name='index'),
url(r'^purchase/$', views.purchase_detail, name='purchase')
]

I used the '$' twice. So a simple change worked:

urlpatterns = [
url(r'^admin/', include(admin.site.urls )),
url(r'^cp/', include('card_purchase.urls' )),
]

Notice the change in the second url! My url.py for my card_purchases app looks like this:

urlpatterns = [
url(r'^$', views.index, name='index'),
url(r'^purchase/$', views.purchase_detail, name='purchase')
]

Apart from this, I can confirm that quotes around named urls are crucial!

If you're accessing this via a View then try sp_recompile or refreshing views.

sp_recompile:

Causes stored procedures, triggers, and user-defined functions to be recompiled the next time that they are run. It does this by dropping the existing plan from the procedure cache forcing a new plan to be created the next time that the procedure or trigger is run. In a SQL Server Profiler collection, the event SP:CacheInsert is logged instead of the event SP:Recompile.

Arguments

[ @objname= ] 'object'

The qualified or unqualified name of a stored procedure, trigger, table, view, or user-defined function in the current database. object is nvarchar(776), with no default. If object is the name of a stored procedure, trigger, or user-defined function, the stored procedure, trigger, or function will be recompiled the next time that it is run. If object is the name of a table or view, all the stored procedures, triggers, or user-defined functions that reference the table or view will be recompiled the next time that they are run.

Return Code Values

0 (success) or a nonzero number (failure)

Remarks

sp_recompile looks for an object in the current database only.

The queries used by stored procedures, or triggers, and user-defined functions are optimized only when they are compiled. As indexes or other changes that affect statistics are made to the database, compiled stored procedures, triggers, and user-defined functions may lose efficiency. By recompiling stored procedures and triggers that act on a table, you can reoptimize the queries.

When I stumbled up on this answer I was looking for a way to get an output that is easy to parse. For me the option --with-colons did the trick:

$ gpg --with-colons file

ssb::4096:1:BBBBBBBBBBBBBBBB:YYYY-MM-DD::::

The command curl http://localhost:8080/job/someJob/build?delay=0sec can run a Jenkins job, where someJob is the name of the Jenkins job.

Search for the "hooks" folder in your hidden .git folder. Rename the "post-commit.sample" file to "post-commit". Open it with Notepad, remove the ": Nothing" line and paste the above command into it.

That's it. Whenever you do a commit, Git will trigger the post-commit commands defined in the file.

Interesting question!

capitalize transforms every first letter of a word to uppercase, but it does not transform the other letters to lowercase. Not even the :first-letter pseudo-class will cut it (because it applies to the first letter of each element, not each word), and I can't see a way of combining lowercase and capitalize to get the desired outcome.

So as far as I can see, this is indeed impossible to do with CSS.

@Harmen shows good-looking PHP and jQuery workarounds in his answer.

This was a really silly one for me. Adding this here as it's one of the more popular threads on svc 404 issues.

I had in my Project Settings' \ Web \ Project URL, pasted:

http://blah.webservice.local.blahblah.com/Blah.svc

And for some unknown reason (having done this a thousand times) didn't spot straight away that the name of the .svc file was at the end.

DOH!

I had just pasted the address from my WCF test client and hadn't checked it sufficiently. What this did in the background was create an IIS application at the .svc address and I was getting nothing out of IIS. I couldn't work out how I couldn't even hit the .svc file.

Simple fix, obviously, just remove the application in IIS and change the project URL.

After almost 20 years at this, you can still make schoolboy errors / rookie mistakes. Hope this helps someone.

Found the solution as below.... posting it as it could help somebody else too :)

DateFormat format = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
Date date = format.parse("2014-04-24 11:15:00");

GregorianCalendar cal = new GregorianCalendar();
cal.setTime(date);

XMLGregorianCalendar xmlGregCal =  DatatypeFactory.newInstance().newXMLGregorianCalendar(cal);

System.out.println(xmlGregCal);

Output:

2014-04-24T11:15:00.000+02:00

i use firebase-database in html signup but last error i cannot understand if anybody know tell me . error is "Failed to load resource: the server responded with a status of 404 ()"

The problem is the std namespace you are missing. cout is in the std namespace.
Add using namespace std; after the #include

As I'm trying to remove an EventListener within a Protractor test and do not have access to the Listener in the test, the following works to remove all event listeners of a single type:

function(eventType){
    getEventListeners(window).[eventType].forEach(
        function(e){
            window.removeEventListener(eventType, e.listener)
        }
    );
}

I hope this helps someone as previous answer were using the "remove" method which since then does not work anymore.

DataTable dt = myDataRowCollection.CopyToDataTable<DataRow>();

If you use the SQLite DB-Browser you can change the default value in this way:

1. Choose database structure
2. select the table
3. modify table
4. in your column put under 'default value' the value: =(datetime('now','localtime'))

I recommend to make an update of your database before, because a wrong format in the value can lead to problems in the SQLLite Browser.

It could be some other line as well. PHP is not always that exact.

Probably you are just missing a semicolon on previous line.

How to reproduce this error, put this in a file called a.php:

<?php
  $a = 5
  $b = 7;        // Error happens here.
  print $b;
?>

Run it:

eric@dev ~ $ php a.php

PHP Parse error:  syntax error, unexpected T_VARIABLE in
/home/el/code/a.php on line 3

Explanation:

The PHP parser converts your program to a series of tokens. A T_VARIABLE is a Token of type VARIABLE. When the parser processes tokens, it tries to make sense of them, and throws errors if it receives a variable where none is allowed.

In the simple case above with variable $b, the parser tried to process this:

$a = 5 $b = 7;

The PHP parser looks at the $b after the 5 and says "that is unexpected".

Use the partial argument of sort(). For the second highest value:

n <- length(x)
sort(x,partial=n-1)[n-1]

I solved it with library PHP_PDO , because my hosting provider didn't accept my requirement for installation of PDO driver to apache server.

HTML

<div id="replaceMe">i need to be replaced</div>
<div id="iamReplacement">i am replacement</div>

JavaScript

jQuery('#replaceMe').replaceWith(jQuery('#iamReplacement'));

I think token should be handled just like password. As such, they should be encrypted in DB.

I'n doing something like this to generate a unique new token for a model:

key = ActiveSupport::KeyGenerator
                .new(Devise.secret_key)
                .generate_key("put some random or the name of the key")

loop do
  raw = SecureRandom.urlsafe_base64(nil, false)
  enc = OpenSSL::HMAC.hexdigest('SHA256', key, raw)

  break [raw, enc] unless Model.exist?(token: enc)
end

Please explain your problem. You say:

But this involves adding character " to the string.

What problem is that? You can't type string foo = "Foo"bar"";, because that'll invoke a compile error. As for the adding part, in string size terms that is not true:

@"""".Length == "\"".Length == 1

var newObj = { a: 4, b: 0.5 , c: 0.35, d: 5 };
var maxValue = Math.max(...Object.values(newObj))
var minValue = Math.min(...Object.values(newObj))

Kotlin helper method to attach click to copy Texts on a TextView

Put this method somewhere in Util class. This method attach click listener on textview to Copy Content of textView to a clipText on click of that textView

/**
 * Param:  cliplabel, textview, context
 */
fun attachClickToCopyText(textView: TextView?, clipLabel: String, context: Context?) {
    if (textView != null && null != context) {
        textView.setOnClickListener {
            val clipboard = context.getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager
            val clip = ClipData.newPlainText(clipLabel, textView!!.text)
            clipboard.primaryClip = clip
            Snackbar.make(textView,
                    "Copied $clipLabel", Snackbar.LENGTH_LONG).show()
        }
    }

}

If your list as multiple elements that need to be converted to numeric, you can achieve this with lapply(a, as.numeric).

With PostgreSQL there are a number of date/time functions available, see here.

In your example, you could use:

SELECT * FROM myTable WHERE date_trunc('day', dt) = 'YYYY-MM-DD';

If you are running this query regularly, it is possible to create an index using the date_trunc function as well:

CREATE INDEX date_trunc_dt_idx ON myTable ( date_trunc('day', dt) );

One advantage of this is there is some more flexibility with timezones if required, for example:

CREATE INDEX date_trunc_dt_idx ON myTable ( date_trunc('day', dt at time zone 'Australia/Sydney') );
SELECT * FROM myTable WHERE date_trunc('day', dt at time zone 'Australia/Sydney') = 'YYYY-MM-DD';

This is my code to add paddingRight and paddingBottom to a View to dodge the Navigation Bar. I combined some of the answers here and made a special clause for landscape orientation together with isInMultiWindowMode. The key is to read navigation_bar_height, but also check config_showNavigationBar to make sure we should actually use the height.

None of the previous solutions worked for me. As of Android 7.0 you have to take Multi Window Mode into consideration. This breaks the implementations comparing display.realSize with display.size since realSize gives you the dimensions of the whole screen (both split windows) and size only gives you the dimensions of your App window. Setting padding to this difference will leave your whole view being padding.

/** Adds padding to a view to dodge the navigation bar.

    Unfortunately something like this needs to be done since there
    are no attr or dimens value available to get the navigation bar
    height (as of December 2016). */
public static void addNavigationBarPadding(Activity context, View v) {
    Resources resources = context.getResources();
    if (hasNavigationBar(resources)) {
        int orientation = resources.getConfiguration().orientation;
        int size = getNavigationBarSize(resources);
        switch (orientation) {
        case Configuration.ORIENTATION_LANDSCAPE:
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N &&
                context.isInMultiWindowMode()) { break; }
            v.setPadding(v.getPaddingLeft(), v.getPaddingTop(),
                         v.getPaddingRight() + size, v.getPaddingBottom());
            break;
        case Configuration.ORIENTATION_PORTRAIT:
            v.setPadding(v.getPaddingLeft(), v.getPaddingTop(),
                         v.getPaddingRight(), v.getPaddingBottom() + size);
            break;
        }
    }
}

private static int getNavigationBarSize(Resources resources) {
    int resourceId = resources.getIdentifier("navigation_bar_height",
                                             "dimen", "android");
    return resourceId > 0 ? resources.getDimensionPixelSize(resourceId) : 0;
}

private static boolean hasNavigationBar(Resources resources) {
    int hasNavBarId = resources.getIdentifier("config_showNavigationBar",
                                              "bool", "android");
    return hasNavBarId > 0 && resources.getBoolean(hasNavBarId);
}

The non-recursive version of the function is not too hard - here it is for integers:

long powi(long x, unsigned n)
{
    long p = x;
    long r = 1;

    while (n > 0)
    {
        if (n % 2 == 1)
            r *= p;
        p *= p;
        n /= 2;
    }

    return(r);
}

(Hacked out of code for raising a double value to an integer power - had to remove the code to deal with reciprocals, for example.)

You don't need the 'values' clause when using a 'select' as your source.

insert into table1 (col1, col2) 
select t1.col1, t2.col2 from oldtable1 t1, oldtable2 t2;

bash doesn't know boolean variables, nor does test (which is what gets called when you use [).

A solution would be:

if $myVar ; then ... ; fi

because true and false are commands that return 0 or 1 respectively which is what if expects.

Note that the values are "swapped". The command after if must return 0 on success while 0 means "false" in most programming languages.

SECURITY WARNING: This works because BASH expands the variable, then tries to execute the result as a command! Make sure the variable can't contain malicious code like rm -rf /

Not sure if this does all expected things, but you can do just like that:

>>> del mymodule
>>> import mymodule

The #1 answer has problems:

• Won't work on mac.
• If a file is installed which includes spaces or other special characters, the xargs command will fail, and delete any files/directories which matched the individual words.
• the -r in rm -rf is unnecessary and at worst could delete things you don't want to.

Instead, for unix-like:

sudo python setup.py install --record files.txt
# inspect files.txt to make sure it looks ok. Then:
tr '\n' '\0' < files.txt | xargs -0 sudo rm -f --

And for windows:

python setup.py bdist_wininst
dist/foo-1.0.win32.exe

There are also unsolvable problems with uninstalling setup.py install which won't bother you in a typical case. For a more complete answer, see this wiki page:

I've found the very simple answer: isAdded():

Return true if the fragment is currently added to its activity.

@Override
protected void onPostExecute(Void result){
    if(isAdded()){
        getResources().getString(R.string.app_name);
    }
}

To avoid onPostExecute from being called when the Fragment is not attached to the Activity is to cancel the AsyncTask when pausing or stopping the Fragment. Then isAdded() would not be necessary anymore. However, it is advisable to keep this check in place.

You can use - matplotlib.gridspec.GridSpec

Check - https://matplotlib.org/stable/api/_as_gen/matplotlib.gridspec.GridSpec.html

The short answer is yes, yes there is a way to get around mysql_real_escape_string(). #For Very OBSCURE EDGE CASES!!!

The long answer isn't so easy. It's based off an attack demonstrated here.

The Attack

So, let's start off by showing the attack...

mysql_query('SET NAMES gbk');
$var = mysql_real_escape_string("\xbf\x27 OR 1=1 /*");
mysql_query("SELECT * FROM test WHERE name = '$var' LIMIT 1");

In certain circumstances, that will return more than 1 row. Let's dissect what's going on here:

1. Selecting a Character Set

   mysql_query('SET NAMES gbk');
   

   For this attack to work, we need the encoding that the server's expecting on the connection both to encode ' as in ASCII i.e. 0x27 and to have some character whose final byte is an ASCII \ i.e. 0x5c. As it turns out, there are 5 such encodings supported in MySQL 5.6 by default: big5, cp932, gb2312, gbk and sjis. We'll select gbk here.

   Now, it's very important to note the use of SET NAMES here. This sets the character set ON THE SERVER. If we used the call to the C API function mysql_set_charset(), we'd be fine (on MySQL releases since 2006). But more on why in a minute...

2. The Payload

   The payload we're going to use for this injection starts with the byte sequence 0xbf27. In gbk, that's an invalid multibyte character; in latin1, it's the string ¿'. Note that in latin1 and gbk, 0x27 on its own is a literal ' character.

   We have chosen this payload because, if we called addslashes() on it, we'd insert an ASCII \ i.e. 0x5c, before the ' character. So we'd wind up with 0xbf5c27, which in gbk is a two character sequence: 0xbf5c followed by 0x27. Or in other words, a valid character followed by an unescaped '. But we're not using addslashes(). So on to the next step...

3. mysql_real_escape_string()

   The C API call to mysql_real_escape_string() differs from addslashes() in that it knows the connection character set. So it can perform the escaping properly for the character set that the server is expecting. However, up to this point, the client thinks that we're still using latin1 for the connection, because we never told it otherwise. We did tell the server we're using gbk, but the client still thinks it's latin1.

   Therefore the call to mysql_real_escape_string() inserts the backslash, and we have a free hanging ' character in our "escaped" content! In fact, if we were to look at $var in the gbk character set, we'd see:

   ?' OR 1=1 /*

   Which is exactly what the attack requires.

4. The Query

   This part is just a formality, but here's the rendered query:

   SELECT * FROM test WHERE name = '?' OR 1=1 /*' LIMIT 1
   

Congratulations, you just successfully attacked a program using mysql_real_escape_string()...

The Bad

It gets worse. PDO defaults to emulating prepared statements with MySQL. That means that on the client side, it basically does a sprintf through mysql_real_escape_string() (in the C library), which means the following will result in a successful injection:

$pdo->query('SET NAMES gbk');
$stmt = $pdo->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$stmt->execute(array("\xbf\x27 OR 1=1 /*"));

Now, it's worth noting that you can prevent this by disabling emulated prepared statements:

$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);

This will usually result in a true prepared statement (i.e. the data being sent over in a separate packet from the query). However, be aware that PDO will silently fallback to emulating statements that MySQL can't prepare natively: those that it can are listed in the manual, but beware to select the appropriate server version).

The Ugly

I said at the very beginning that we could have prevented all of this if we had used mysql_set_charset('gbk') instead of SET NAMES gbk. And that's true provided you are using a MySQL release since 2006.

If you're using an earlier MySQL release, then a bug in mysql_real_escape_string() meant that invalid multibyte characters such as those in our payload were treated as single bytes for escaping purposes even if the client had been correctly informed of the connection encoding and so this attack would still succeed. The bug was fixed in MySQL 4.1.20, 5.0.22 and 5.1.11.

But the worst part is that PDO didn't expose the C API for mysql_set_charset() until 5.3.6, so in prior versions it cannot prevent this attack for every possible command! It's now exposed as a DSN parameter.

The Saving Grace

As we said at the outset, for this attack to work the database connection must be encoded using a vulnerable character set. utf8mb4 is not vulnerable and yet can support every Unicode character: so you could elect to use that instead—but it has only been available since MySQL 5.5.3. An alternative is utf8, which is also not vulnerable and can support the whole of the Unicode Basic Multilingual Plane.

Alternatively, you can enable the NO_BACKSLASH_ESCAPES SQL mode, which (amongst other things) alters the operation of mysql_real_escape_string(). With this mode enabled, 0x27 will be replaced with 0x2727 rather than 0x5c27 and thus the escaping process cannot create valid characters in any of the vulnerable encodings where they did not exist previously (i.e. 0xbf27 is still 0xbf27 etc.)—so the server will still reject the string as invalid. However, see @eggyal's answer for a different vulnerability that can arise from using this SQL mode.

Safe Examples

The following examples are safe:

mysql_query('SET NAMES utf8');
$var = mysql_real_escape_string("\xbf\x27 OR 1=1 /*");
mysql_query("SELECT * FROM test WHERE name = '$var' LIMIT 1");

Because the server's expecting utf8...

mysql_set_charset('gbk');
$var = mysql_real_escape_string("\xbf\x27 OR 1=1 /*");
mysql_query("SELECT * FROM test WHERE name = '$var' LIMIT 1");

Because we've properly set the character set so the client and the server match.

$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
$pdo->query('SET NAMES gbk');
$stmt = $pdo->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$stmt->execute(array("\xbf\x27 OR 1=1 /*"));

Because we've turned off emulated prepared statements.

$pdo = new PDO('mysql:host=localhost;dbname=testdb;charset=gbk', $user, $password);
$stmt = $pdo->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$stmt->execute(array("\xbf\x27 OR 1=1 /*"));

Because we've set the character set properly.

$mysqli->query('SET NAMES gbk');
$stmt = $mysqli->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$param = "\xbf\x27 OR 1=1 /*";
$stmt->bind_param('s', $param);
$stmt->execute();

Because MySQLi does true prepared statements all the time.

Wrapping Up

If you:

• Use Modern Versions of MySQL (late 5.1, all 5.5, 5.6, etc) AND mysql_set_charset() / $mysqli->set_charset() / PDO's DSN charset parameter (in PHP = 5.3.6)

OR

• Don't use a vulnerable character set for connection encoding (you only use utf8 / latin1 / ascii / etc)

You're 100% safe.

Otherwise, you're vulnerable even though you're using mysql_real_escape_string()...

In computer programming, particularly in the C, C++, and C# programming languages, a variable or object declared with the volatile keyword usually has special properties related to optimization and/or threading. Generally speaking, the volatile keyword is intended to prevent the (pseudo)compiler from applying any optimizations on the code that assume values of variables cannot change "on their own."

You are mixing tabs and spaces. Don't do that. Specifically, the __init__ function body is indented with tabs while your on_data method is not.

Here is a screenshot of your code in my text editor; I set the tab stop to 8 spaces (which is what Python uses) and selected the text, which causes the editor to display tabs with continuous horizontal lines:

You have your editor set to expanding tabs to every fourth column instead, so the methods appear to line up.

Run your code with:

python -tt scriptname.py

and fix all errors that finds. Then configure your editor to use spaces only for indentation; a good editor will insert 4 spaces every time you use the TAB key.

If you have Java installed, java.exe will be in the bin directory. If you can't find it, download and install Java, then use the install path + "\bin".

It does not allow it, use interface to achieve it.

Why it is so?

Here is the answer: It's allowed the compiler to make a very reasoned and rational decision that was always going to consistent about what was inherited and where it was inherited from so that when you did casting and you always know exactly which implementation you were dealing with.

it's like this :)

window.addEventListener("scroll", (event) => {
    let scroll = this.scrollY;
    console.log(scroll)
});

Probably you are trying to access the excel with the index 0, please note that Excel rows/columns start from 1.

If you have multiple versions of a package / module, you need to be using virtualenv (emphasis mine):

virtualenv is a tool to create isolated Python environments.

The basic problem being addressed is one of dependencies and versions, and indirectly permissions. Imagine you have an application that needs version 1 of LibFoo, but another application requires version 2. How can you use both these applications? If you install everything into /usr/lib/python2.7/site-packages (or whatever your platform’s standard location is), it’s easy to end up in a situation where you unintentionally upgrade an application that shouldn’t be upgraded.

Or more generally, what if you want to install an application and leave it be? If an application works, any change in its libraries or the versions of those libraries can break the application.

Also, what if you can’t install packages into the global site-packages directory? For instance, on a shared host.

In all these cases, virtualenv can help you. It creates an environment that has its own installation directories, that doesn’t share libraries with other virtualenv environments (and optionally doesn’t access the globally installed libraries either).

That's why people consider insert(0, to be wrong -- it's an incomplete, stopgap solution to the problem of managing multiple environments.

I think that it's around 2GB. While the answer by Pete Kirkham is very interesting and probably holds truth, I have allocated upwards of 3GB without error, however it did not use 3GB in practice. That might explain why you were able to allocate 2.5 GB on 2GB RAM with no swap space. In practice, it wasn't using 2.5GB.

In Java 8, it can be done using

String[] arrayFromList = fromlist.stream().toArray(String[]::new);

I think the only way is by using internel PHP code like MANOJ and Fernando suggest.

curl post/get in php file on your server --> call this php file with ajax

The PHP file let say (fb.php):

$commentdata=$_GET['commentdata'];
$fbUrl="https://graph.facebook.com/16453004404_481759124404/comments?access_token=my_token";
curl_setopt($ch, CURLOPT_URL,$fbUrl);
curl_setopt($ch, CURLOPT_POST, 1);
// POST data here
curl_setopt($ch, CURLOPT_POSTFIELDS,
        "message=".$commentdata);

// receive server response ...
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$server_output = curl_exec ($ch);
echo $server_output;
curl_close ($ch);

Than use AJAX GET to

fb.php?commentmeta=your comment goes here

from your server.

Or do this with simple HTML and JavaScript from externel server:

Message: <input type="text" id="message">
<input type="submit" onclick='PostMessage()'>
<script>
function PostMessage() {
var comment = document.getElementById('message').value;
    window.location.assign('http://yourdomain.tld/fb.php?commentmeta='+comment)
}
</script>

I installed ArcGIS Pro 1.4 and it didn't register the Python 3.5.2 it installed which prevented me from installing any add-ons. I resolved this by using the "reg" command in an Administrator PowerShell session to manually create and populate the necessary registry keys/values (where Python is installed in C:\Python35):

reg add "HKLM\Software\Python\PythonCore\3.5\Help\Main Python Documentation" /reg:64 /ve /t REG_SZ /d "C:\Python35\Doc\Python352.chm"
reg add "HKLM\Software\Python\PythonCore\3.5\InstallPath" /reg:64 /ve /t REG_SZ /d "C:\Python35\"
reg add "HKLM\Software\Python\PythonCore\3.5\InstallPath\InstallGroup" /reg:64 /ve /t REG_SZ /d "Python 3.5"
reg add "HKLM\Software\Python\PythonCore\3.5\PythonPath" /reg:64 /ve /t REG_SZ /d "C:\Python35\Lib;C:\Python35\DLLs;C:\Python35\Lib\lib-tk"

I find this easier than using Registry Editor but that's solely a personal preference.

The same commands can be executed in CMD.EXE session if you prefer; just make sure you run it as Administrator.

Recursion in Python works just as recursion in an other language, with the recursive construct defined in terms of itself:

For example a recursive class could be a binary tree (or any tree):

class tree():
    def __init__(self):
        '''Initialise the tree'''
        self.Data = None
        self.Count = 0
        self.LeftSubtree = None
        self.RightSubtree = None

    def Insert(self, data):
        '''Add an item of data to the tree'''
        if self.Data == None:
            self.Data = data
            self.Count += 1
        elif data < self.Data:
            if self.LeftSubtree == None:
                # tree is a recurive class definition
                self.LeftSubtree = tree()
            # Insert is a recursive function
            self.LeftSubtree.Insert(data)
        elif data == self.Data:
            self.Count += 1
        elif data > self.Data:
            if self.RightSubtree == None:
                self.RightSubtree = tree()
            self.RightSubtree.Insert(data)

if __name__ == '__main__':
    T = tree()
    # The root node
    T.Insert('b')
    # Will be put into the left subtree
    T.Insert('a')
    # Will be put into the right subtree
    T.Insert('c')

As already mentioned a recursive structure must have a termination condition. In this class, it is not so obvious because it only recurses if new elements are added, and only does it a single time extra.

Also worth noting, python by default has a limit to the depth of recursion available, to avoid absorbing all of the computer's memory. On my computer this is 1000. I don't know if this changes depending on hardware, etc. To see yours :

import sys
sys.getrecursionlimit()

and to set it :

import sys #(if you haven't already)
sys.setrecursionlimit()

edit: I can't guarentee that my binary tree is the most efficient design ever. If anyone can improve it, I'd be happy to hear how

Very often you have no option to setup the sending server so what I did I changed the XMLHttpRequest.open call in my javascript to a local get-file.php file where I have the following code in it:

<?php_x000D_
  $file = file($_GET['url']);_x000D_
  echo implode('', $file);_x000D_
?>

javascript is doing this:

var xhttp = new XMLHttpRequest();_x000D_
xhttp.onreadystatechange = function() {_x000D_
  if (this.readyState == 4 && this.status == 200) {_x000D_
    // File content is now in the this.responseText_x000D_
  }_x000D_
};_x000D_
xhttp.open("GET", "get-file.php?url=http://site/file", true);_x000D_
xhttp.send();

In my case this solved the restriction/situation just perfectly. No need to hack Firefox or servers. Just load your javascript/html file with that small php file into the server and you're done.

You could use javax.servlet.Filter if there wasn't a requirement to log java method that been executed.

But with this requirement you have to access information stored in handlerMapping of DispatcherServlet. That said, you can override DispatcherServlet to accomplish logging of request/response pair.

Below is an example of idea that can be further enhanced and adopted to your needs.

public class LoggableDispatcherServlet extends DispatcherServlet {

    private final Log logger = LogFactory.getLog(getClass());

    @Override
    protected void doDispatch(HttpServletRequest request, HttpServletResponse response) throws Exception {
        if (!(request instanceof ContentCachingRequestWrapper)) {
            request = new ContentCachingRequestWrapper(request);
        }
        if (!(response instanceof ContentCachingResponseWrapper)) {
            response = new ContentCachingResponseWrapper(response);
        }
        HandlerExecutionChain handler = getHandler(request);

        try {
            super.doDispatch(request, response);
        } finally {
            log(request, response, handler);
            updateResponse(response);
        }
    }

    private void log(HttpServletRequest requestToCache, HttpServletResponse responseToCache, HandlerExecutionChain handler) {
        LogMessage log = new LogMessage();
        log.setHttpStatus(responseToCache.getStatus());
        log.setHttpMethod(requestToCache.getMethod());
        log.setPath(requestToCache.getRequestURI());
        log.setClientIp(requestToCache.getRemoteAddr());
        log.setJavaMethod(handler.toString());
        log.setResponse(getResponsePayload(responseToCache));
        logger.info(log);
    }

    private String getResponsePayload(HttpServletResponse response) {
        ContentCachingResponseWrapper wrapper = WebUtils.getNativeResponse(response, ContentCachingResponseWrapper.class);
        if (wrapper != null) {

            byte[] buf = wrapper.getContentAsByteArray();
            if (buf.length > 0) {
                int length = Math.min(buf.length, 5120);
                try {
                    return new String(buf, 0, length, wrapper.getCharacterEncoding());
                }
                catch (UnsupportedEncodingException ex) {
                    // NOOP
                }
            }
        }
        return "[unknown]";
    }

    private void updateResponse(HttpServletResponse response) throws IOException {
        ContentCachingResponseWrapper responseWrapper =
            WebUtils.getNativeResponse(response, ContentCachingResponseWrapper.class);
        responseWrapper.copyBodyToResponse();
    }

}

HandlerExecutionChain - contains the information about request handler.

You then can register this dispatcher as following:

    @Bean
    public ServletRegistrationBean dispatcherRegistration() {
        return new ServletRegistrationBean(dispatcherServlet());
    }

    @Bean(name = DispatcherServletAutoConfiguration.DEFAULT_DISPATCHER_SERVLET_BEAN_NAME)
    public DispatcherServlet dispatcherServlet() {
        return new LoggableDispatcherServlet();
    }

And here's the sample of logs:

http http://localhost:8090/settings/test
i.g.m.s.s.LoggableDispatcherServlet      : LogMessage{httpStatus=500, path='/error', httpMethod='GET', clientIp='127.0.0.1', javaMethod='HandlerExecutionChain with handler [public org.springframework.http.ResponseEntity<java.util.Map<java.lang.String, java.lang.Object>> org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletRequest)] and 3 interceptors', arguments=null, response='{"timestamp":1472475814077,"status":500,"error":"Internal Server Error","exception":"java.lang.RuntimeException","message":"org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.RuntimeException","path":"/settings/test"}'}

http http://localhost:8090/settings/params
i.g.m.s.s.LoggableDispatcherServlet      : LogMessage{httpStatus=200, path='/settings/httpParams', httpMethod='GET', clientIp='127.0.0.1', javaMethod='HandlerExecutionChain with handler [public x.y.z.DTO x.y.z.Controller.params()] and 3 interceptors', arguments=null, response='{}'}

http http://localhost:8090/123
i.g.m.s.s.LoggableDispatcherServlet      : LogMessage{httpStatus=404, path='/error', httpMethod='GET', clientIp='127.0.0.1', javaMethod='HandlerExecutionChain with handler [public org.springframework.http.ResponseEntity<java.util.Map<java.lang.String, java.lang.Object>> org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletRequest)] and 3 interceptors', arguments=null, response='{"timestamp":1472475840592,"status":404,"error":"Not Found","message":"Not Found","path":"/123"}'}

UPDATE

In case of errors Spring does automatic error handling. Therefore, BasicErrorController#error is shown as request handler. If you want to preserve original request handler, then you can override this behavior at spring-webmvc-4.2.5.RELEASE-sources.jar!/org/springframework/web/servlet/DispatcherServlet.java:971 before #processDispatchResult is called, to cache original handler.

INSERT INTO table
SELECT 'jonny', NULL
  FROM dual -- Not Oracle? No need for dual, drop that line
 WHERE NOT EXISTS (SELECT NULL -- canonical way, but you can select
                               -- anything as EXISTS only checks existence
                     FROM table
                    WHERE name = 'jonny'
                  )

If you want to overwrite only one file:

git fetch
git checkout origin/master <filepath>

If you want to overwrite all changed files:

git fetch
git reset --hard origin/master

(This assumes that you're working on master locally and you want the changes on the origin's master - if you're on a branch, substitute that in instead.)

There is a manual page dedicated to help choosing between mysql, mysqli and PDO at

• http://php.net/manual/en/mysqlinfo.api.choosing.php and
• http://www.php.net/manual/en/mysqlinfo.library.choosing.php

The PHP team recommends mysqli or PDO_MySQL for new development:

It is recommended to use either the mysqli or PDO_MySQL extensions. It is not recommended to use the old mysql extension for new development. A detailed feature comparison matrix is provided below. The overall performance of all three extensions is considered to be about the same. Although the performance of the extension contributes only a fraction of the total run time of a PHP web request. Often, the impact is as low as 0.1%.

The page also has a feature matrix comparing the extension APIs. The main differences between mysqli and mysql API are as follows:

                               mysqli     mysql

If by numbers between 1 and 10 you mean any float that is >= 1 and < 10, then it's easy:

select random() * 9 + 1

This can be easily tested with:

# select min(i), max(i) from (
    select random() * 9 + 1 as i from generate_series(1,1000000)
) q;
       min       |       max
-----------------+------------------
 1.0000083274208 | 9.99999571684748
(1 row)

If you want integers, that are >= 1 and < 10, then it's simple:

select trunc(random() * 9 + 1)

And again, simple test:

# select min(i), max(i) from (
    select trunc(random() * 9 + 1) as i from generate_series(1,1000000)
) q;
 min | max
-----+-----
   1 |   9
(1 row)

#father {
   position: relative;
}

#son1 {
   position: absolute;
   top: 0;
}

#son2 {
   position: absolute;
   bottom: 0;
}

This works because position: absolute means something like "use top, right, bottom, left to position yourself in relation to the nearest ancestor who has position: absolute or position: relative."

So we make #father have position: relative, and the children have position: absolute, then use top and bottom to position the children.

The solution for me was to set the git path in the Manage Jenkins > Global Tool Configuration settings. In the Git section, I changed the Path to Git executable to /usr/local/bin/git.

echo.|set /p=>file

echo. suppress the "Command ECHO activated"

|set /p= prevent newline (and file is now 0 byte)

I wrote the following code to convert an image from sdcard to a Base64 encoded string to send as a JSON object.And it works great:

String filepath = "/sdcard/temp.png";
File imagefile = new File(filepath);
FileInputStream fis = null;
try {
    fis = new FileInputStream(imagefile);
    } catch (FileNotFoundException e) {
    e.printStackTrace();
}

Bitmap bm = BitmapFactory.decodeStream(fis);
ByteArrayOutputStream baos = new ByteArrayOutputStream();  
bm.compress(Bitmap.CompressFormat.JPEG, 100 , baos);    
byte[] b = baos.toByteArray(); 
encImage = Base64.encodeToString(b, Base64.DEFAULT);

I am not sure why you cannot use "lat" but, if you must you can rename the columns in a derived table.

select latitude from (SELECT lat AS latitude FROM poi_table) p where latitude < 500

using List Comprehensions of python

[range(t,t+10) for t in range(1,1000,10)]

[[1, 2, 3, 4, 5, 6, 7, 8, 9, 10],
 [11, 12, 13, 14, 15, 16, 17, 18, 19, 20],
 [21, 22, 23, 24, 25, 26, 27, 28, 29, 30],....
 ....[981, 982, 983, 984, 985, 986, 987, 988, 989, 990],
 [991, 992, 993, 994, 995, 996, 997, 998, 999, 1000]]

visit this link to know about List Comprehensions

You can also try this:

constructor(props) {
        super(props);
        this.state = {height: props.height, width:props.width};
      }

componentWillMount(){
          console.log("WINDOW : ",window);
          this.setState({height: window.innerHeight + 'px',width:window.innerWidth+'px'});
      }

render() {
        console.log("VIEW : ",this.state);
}

You can use either jQuery Autocomplete or ASP.NET AJAX Toolkit Autocomplete

Why not using exit codes? If a git repository exists in the current directory, then git branch and git tag commands return exit code of 0; otherwise, a non-zero exit code will be returned. This way, you can determine if a git repository exist or not. Simply, you can run:

git tag > /dev/null 2>&1 && [ $? -eq 0 ]

Advantage: Flexibe. It works for both bare and non-bare repositories, and in sh, zsh and bash.

Explanation

1. git tag: Getting tags of the repository to determine if exists or not.
2. > /dev/null 2>&1: Preventing from printing anything, including normal and error outputs.
3. [ $? -eq 0 ]: Check if the previous command returned with exit code 0 or not. As you may know, every non-zero exit means something bad happened. $? gets the exit code of the previous command, and [, -eq and ] perform the comparison.

As an example, you can create a file named check-git-repo with the following contents, make it executable and run it:

#!/bin/sh

if git tag > /dev/null 2>&1 && [ $? -eq 0 ]; then
    echo "Repository exists!";
else
    echo "No repository here.";
fi

Another take on this (heavily derived from solutions above) but

• uses null for padding
• does not use lambda (never been a fan)

• tested with python 2.7 and 3.6.5

  #!/usr/bin/python2.7
  # you'll have to adjust for your setup, e.g., #!/usr/bin/python3
  
  
  import base64, re
  from Crypto.Cipher import AES
  from Crypto import Random
  from django.conf import settings
  
  class AESCipher:
      """
        Usage:
        aes = AESCipher( settings.SECRET_KEY[:16], 32)
        encryp_msg = aes.encrypt( 'ppppppppppppppppppppppppppppppppppppppppppppppppppppppp' )
        msg = aes.decrypt( encryp_msg )
        print("'{}'".format(msg))
      """
      def __init__(self, key, blk_sz):
          self.key = key
          self.blk_sz = blk_sz
  
      def encrypt( self, raw ):
          if raw is None or len(raw) == 0:
              raise NameError("No value given to encrypt")
          raw = raw + '\0' * (self.blk_sz - len(raw) % self.blk_sz)
          raw = raw.encode('utf-8')
          iv = Random.new().read( AES.block_size )
          cipher = AES.new( self.key.encode('utf-8'), AES.MODE_CBC, iv )
          return base64.b64encode( iv + cipher.encrypt( raw ) ).decode('utf-8')
  
      def decrypt( self, enc ):
          if enc is None or len(enc) == 0:
              raise NameError("No value given to decrypt")
          enc = base64.b64decode(enc)
          iv = enc[:16]
          cipher = AES.new(self.key.encode('utf-8'), AES.MODE_CBC, iv )
          return re.sub(b'\x00*$', b'', cipher.decrypt( enc[16:])).decode('utf-8')
  

You can use TRIM('"' FROM '"this "is" a test"') which returns: this "is" a test

As this is one of the top questions about external redirect in WebView, here is a "modern" solution on Kotlin:

webView.webViewClient = object : WebViewClient() {
        override fun shouldOverrideUrlLoading(
            view: WebView?,
            request: WebResourceRequest?
        ): Boolean {
            val url = request?.url ?: return false
            //you can do checks here e.g. url.host equals to target one
            startActivity(Intent(Intent.ACTION_VIEW, url))
            return true
        }
    }

The HTML5 spec says that the type attribute is purely advisory and explains in detail how browsers should act if it's omitted (too much to quote here). It doesn't explicitly say that an omitted type attribute is either valid or invalid, but you can safely omit it knowing that browsers will still react as you expect.

Update 2018

Bootstrap 2.x

You could create a new CSS class such as:

.img-center {margin:0 auto;}

And then, add this to each IMG:

 <img src="images/2.png" class="img-responsive img-center">

OR, just override the .img-responsive if you're going to center all images..

 .img-responsive {margin:0 auto;}

Demo: http://bootply.com/86123

Bootstrap 3.x

EDIT - With the release of Bootstrap 3.0.1, the center-block class can now be used without any additional CSS..

 <img src="images/2.png" class="img-responsive center-block">

Bootstrap 4

In Bootstrap 4, the mx-auto class (auto x-axis margins) can be used to center images that are display:block. However, img is display:inline by default so text-center can be used on the parent.

<div class="container">
    <div class="row">
        <div class="col-12">
            <img class="mx-auto d-block" src="//placehold.it/200">  
        </div>
    </div>
    <div class="row">
        <div class="col-12 text-center">
            <img src="//placehold.it/200">  
        </div>
    </div>
</div>

Bootsrap 4 - center image demo

  class Swap2Values{
    public static void main(String[] args){
       int a = 20, b = 10;

       //before swaping
       System.out.print("Before Swapping the values of a and b are: a = "+a+", b = "+b);

       //swapping
       a = a + b;
       b = a - b;
       a = a - b;

       //after swapping
      System.out.print("After Swapping the values of a and b are: a = "+a+", b = "+b);
    }
  }

You can use the open pragma.

For eg. below sets STDOUT, STDIN & STDERR to use UTF-8....

use open qw/:std :utf8/;

We can divide data into a particular ratio here it is 80% train and 20% in a test dataset.

ind <- sample(2, nrow(dataName), replace = T, prob = c(0.8,0.2))
train <- dataName[ind==1, ]
test <- dataName[ind==2, ]

<form id="uploadbanner" enctype="multipart/form-data" method="post" action="#">
   <input id="fileupload" name="myfile" type="file" />
   <input type="submit" value="submit" id="submit" />
</form>

To upload a file, it is essential to set enctype="multipart/form-data" on your form

You need that form type and then some php to process the file :)

You should probably check out Uploadify if you want something very customisable out of the box.

If you're wondering whether to type HEAD^ or HEAD~ in your command, just use either:

They're both names for the same commit - the first parent of the current commit.

Likewise with master~ and master^ - both names for the first parent of master.

In the same way as 2 + 2 and 2 x 2 are both 4 - they're different ways of getting there, but the answer is the same.

This answers the question: What's the difference between HEAD^ and HEAD~ in Git?

If you just did a merge (so your current commit has more than one parent), or you're still interested in how the caret and tilde work, see the other answers (which I won't duplicate here) for an in-depth explanation, as well as how to use them repeatedly (e.g.HEAD~~~), or with numbers (e.g.HEAD^2). Otherwise, I hope this answer saves you some time.

Yes, it means "not equal", either less than or greater than. e.g

If x <> y Then

can be read as

if x is less than y or x is greater than y then

The logical outcome being "If x is anything except equal to y"

Below is the Dynamic Script to enable or disable the Triggers.

select 'alter table '+ (select Schema_name(schema_id) from sys.objects o 
where o.object_id = parent_id) + '.'+object_name(parent_id) + ' ENABLE TRIGGER '+
Name as EnableScript,*
from sys.triggers t 
where is_disabled = 1

I had read yesterday that the issue was fixed for someone when that person cleared cookies. I had tried that but it did not work for me.

Checking the following section in DatabaseInterface.class.php,

        define(
            'PMA_MYSQL_INT_VERSION',
            PMA_Util::cacheGet('PMA_MYSQL_INT_VERSION', true)
        );

I figured that somehow cache is the problem. So, I remembered that I was restarting the service instead of doing a start and stop.

# restart the service
systemd restart php-fpm

# start and stop the service
systemd stop php-fpm
systemd start php-fpm

Doing a stop followed by a start fixed the issue for me.

If there is no ORDER BY, a UNION ALL may bring rows back as it goes, whereas a UNION would make you wait until the very end of the query before giving you the whole result set at once. This can make a difference in a time-out situation - a UNION ALL keeps the connection alive, as it were.

So if you have a time-out issue, and there's no sorting, and duplicates aren't an issue, UNION ALL may be rather helpful.

As your input is in string you are getting value error message use countvectorizer it will convert data set in to sparse matrix and train your ml algorithm you will get the result

m - for classes that set margin, like this :

• mt - for classes that set margin-top
• mb - for classes that set margin-bottom
• ml - for classes that set margin-left
• mr - for classes that set margin-right
• mx - for classes that set both margin-left and margin-right
• my - for classes that set both margin-top and margin-bottom

Where size is one of margin :

• 0 - for classes that eliminate the margin by setting it to 0, like mt-0
• 1 - (by default) for classes that set the margin to $spacer * .25, like mt-1
• 2 - (by default) for classes that set the margin to $spacer * .5, like mt-2

I use zope.event. It's the most bare bones you can imagine. :-) In fact, here is the complete source code:

subscribers = []

def notify(event):
    for subscriber in subscribers:
        subscriber(event)

Note that you can't send messages between processes, for example. It's not a messaging system, just an event system, nothing more, nothing less.

main is a static method. It cannot refer to balance, which is an attribute (non-static variable). balance has meaning only when it is referred through an object reference (such as myAccount.balance or yourAccount.balance). But it doesn't have any meaning when it is referred through class (such as Account.balance (whose balance is that?))

I made some changes to your code so that it compiles.

public static void main(String[] args) {
    Account account = new Account(1122, 20000, 4.5);
    account.withdraw(2500);
    account.deposit(3000);

and:

public void withdraw(double withdrawAmount) {
    balance -= withdrawAmount;
}

public void deposit(double depositAmount) {
    balance += depositAmount;
}   

Summary

With either string concatenation or string interpolation (via template literals).

Here with JavaScript template literal:

function geoPreview() {
    var lat = document.getElementById("lat").value;
    var long = document.getElementById("long").value;

    window.location.href = `http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat=${lat}&lon=${long}&setLatLon=Set`;
}

Both parameters are unused and can be removed.

Remarks

String Concatenation

Join strings with the + operator:

window.location.href = "http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat=" + elemA + "&lon=" + elemB + "&setLatLon=Set";

String Interpolation

For more concise code, use JavaScript template literals to replace expressions with their string representations. Template literals are enclosed by `` and placeholders surrounded with ${}:

window.location.href = `http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat=${elemA}&lon=${elemB}&setLatLon=Set`;

Template literals are available since ECMAScript 2015 (ES6).

return Task.CompletedTask; // this will make the compiler happy

I was not able to find any solution for this type of animation using ViewPropertyAnimator.

Here's an example:

Layout:

<FrameLayout
android:id="@+id/child_view_container"
android:layout_width="match_parent"
android:layout_height="wrap_content">

    <EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/child_view"
        android:gravity="center_horizontal"
        android:layout_gravity="center_horizontal"
    />
</FrameLayout>

Animate - Right to left and exit view:

final childView = findViewById(R.id.child_view);
View containerView = findViewById(R.id.child_view_container);
childView.animate()
  .translationXBy(-containerView.getWidth())
  .setDuration(TRANSLATION_DURATION)
  .setInterpolator(new AccelerateDecelerateInterpolator())
  .setListener(new AnimatorListenerAdapter() {
    @Override
    public void onAnimationEnd(Animator animation) {
        childView.setVisibility(View.GONE);
    }
});

Animate - Right to left enter view:

final View childView = findViewById(R.id.child_view);
View containerView = findViewById(R.id.child_view_container);
childView.setTranslationX(containerView.getWidth());
childView.animate()
    .translationXBy(-containerView.getWidth())
    .setDuration(TRANSLATION_DURATION)
    .setInterpolator(new AccelerateDecelerateInterpolator())
    .setListener(new AnimatorListenerAdapter() {
        @Override
        public void onAnimationStart(Animator animation) {
            childView.setVisibility(View.VISIBLE);
        }
    });

This answer does not address the Debug button (you'd have to design a form and use the buttons on that to do something like the method in your next question). But it does address this part:

now I don't want to lose the comfortableness of the default handler which also point me to the exact line where the error has occured.

First, I'll assume you don't want this in production code - you want it either for debugging or for code you personally will be using. I use a compiler flag to indicate debugging; then if I'm troubleshooting a program, I can easily find the line that's causing the problem.

# Const IsDebug = True

Sub ProcA()
On Error Goto ErrorHandler
' Main code of proc

ExitHere:
    On Error Resume Next
    ' Close objects and stuff here
    Exit Sub

ErrorHandler:
    MsgBox Err.Number & ": " & Err.Description, , ThisWorkbook.Name & ": ProcA"
    #If IsDebug Then
        Stop            ' Used for troubleshooting - Then press F8 to step thru code 
        Resume          ' Resume will take you to the line that errored out
    #Else
        Resume ExitHere ' Exit procedure during normal running
    #End If
End Sub

Note: the exception to Resume is if the error occurs in a sub-procedure without an error handling routine, then Resume will take you to the line in this proc that called the sub-procedure with the error. But you can still step into and through the sub-procedure, using F8 until it errors out again. If the sub-procedure's too long to make even that tedious, then your sub-procedure should probably have its own error handling routine.

There are multiple ways to do this. Sometimes for smaller programs where I know I'm gonna be stepping through it anyway when troubleshooting, I just put these lines right after the MsgBox statement:

    Resume ExitHere         ' Normally exits during production
    Resume                  ' Never will get here
Exit Sub

It will never get to the Resume statement, unless you're stepping through and set it as the next line to be executed, either by dragging the next statement pointer to that line, or by pressing CtrlF9 with the cursor on that line.

Here's an article that expands on these concepts: Five tips for handling errors in VBA. Finally, if you're using VBA and haven't discovered Chip Pearson's awesome site yet, he has a page explaining Error Handling In VBA.

Create one simple FileUtil class & use to create, copy and rename the file

I used uri.toString() and uri.getPath() but not work for me. I finally found this solution.

import android.content.Context;
import android.database.Cursor;
import android.net.Uri;
import android.provider.OpenableColumns;
import android.util.Log;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class FileUtil {
    private static final int EOF = -1;
    private static final int DEFAULT_BUFFER_SIZE = 1024 * 4;

    private FileUtil() {

    }

    public static File from(Context context, Uri uri) throws IOException {
        InputStream inputStream = context.getContentResolver().openInputStream(uri);
        String fileName = getFileName(context, uri);
        String[] splitName = splitFileName(fileName);
        File tempFile = File.createTempFile(splitName[0], splitName[1]);
        tempFile = rename(tempFile, fileName);
        tempFile.deleteOnExit();
        FileOutputStream out = null;
        try {
            out = new FileOutputStream(tempFile);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
        if (inputStream != null) {
            copy(inputStream, out);
            inputStream.close();
        }

        if (out != null) {
            out.close();
        }
        return tempFile;
    }

    private static String[] splitFileName(String fileName) {
        String name = fileName;
        String extension = "";
        int i = fileName.lastIndexOf(".");
        if (i != -1) {
            name = fileName.substring(0, i);
            extension = fileName.substring(i);
        }

        return new String[]{name, extension};
    }

    private static String getFileName(Context context, Uri uri) {
        String result = null;
        if (uri.getScheme().equals("content")) {
            Cursor cursor = context.getContentResolver().query(uri, null, null, null, null);
            try {
                if (cursor != null && cursor.moveToFirst()) {
                    result = cursor.getString(cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME));
                }
            } catch (Exception e) {
                e.printStackTrace();
            } finally {
                if (cursor != null) {
                    cursor.close();
                }
            }
        }
        if (result == null) {
            result = uri.getPath();
            int cut = result.lastIndexOf(File.separator);
            if (cut != -1) {
                result = result.substring(cut + 1);
            }
        }
        return result;
    }

    private static File rename(File file, String newName) {
        File newFile = new File(file.getParent(), newName);
        if (!newFile.equals(file)) {
            if (newFile.exists() && newFile.delete()) {
                Log.d("FileUtil", "Delete old " + newName + " file");
            }
            if (file.renameTo(newFile)) {
                Log.d("FileUtil", "Rename file to " + newName);
            }
        }
        return newFile;
    }

    private static long copy(InputStream input, OutputStream output) throws IOException {
        long count = 0;
        int n;
        byte[] buffer = new byte[DEFAULT_BUFFER_SIZE];
        while (EOF != (n = input.read(buffer))) {
            output.write(buffer, 0, n);
            count += n;
        }
        return count;
    }
}

Use FileUtil class in your code

try {
         File file = FileUtil.from(MainActivity.this,fileUri);
         Log.d("file", "File...:::: uti - "+file .getPath()+" file -" + file + " : " + file .exists());

  } catch (IOException e) {
          e.printStackTrace();
  }

You are getting NullPointerException as the "output" is null when the while loop ends. You can collect the output in some buffer and then use it, something like this-

    StringBuilder buffer = new StringBuilder();
    String output;
    System.out.println("Output from Server .... \n");
    while ((output = br.readLine()) != null) {
        System.out.println(output);
        buffer.append(output);
    }
    output = buffer.toString(); // now you have the output
    conn.disconnect();

myList.Where(item=>item.Name == nameToExtract)

Recent updates to ggplot (0.9.2+) have overhauled the syntax for themes. Most notably, opts() is now deprecated, having been replaced by theme(). Sandy's answer will still (as of Jan '12) generates a chart, but causes R to throw a bunch of warnings.

Here's updated code reflecting current ggplot syntax:

library(ggplot2)
a <- seq(1,20)
b <- a^0.25
df <- as.data.frame(cbind(a,b))

#base ggplot object
p <- ggplot(df, aes(x = a, y = b))

p +
  #plots the points
  geom_point() +

  #theme with white background
  theme_bw() +

  #eliminates background, gridlines, and chart border
  theme(
    plot.background = element_blank(),
    panel.grid.major = element_blank(),
    panel.grid.minor = element_blank(),
    panel.border = element_blank()
  ) +

  #draws x and y axis line
  theme(axis.line = element_line(color = 'black'))

generates:

Here is the best way I found for Python 2:

def inplace_change(file,old,new):
        fin = open(file, "rt")
        data = fin.read()
        data = data.replace(old, new)
        fin.close()

        fin = open(file, "wt")
        fin.write(data)
        fin.close()

An example:

inplace_change('/var/www/html/info.txt','youtub','youtube')

In CSS:

  textarea { 
    border-style: none; 
    border-color: Transparent; 
    overflow: auto;        
  }

A Window is always shown independently, A Page is intended to be shown inside a Frame or inside a NavigationWindow.

The greater sign ( > ) selector in CSS means that the selector on the right is a direct descendant / child of whatever is on the left.

An example:

article > p { }

Means only style a paragraph that comes after an article.

IIUC you want the number of different ID for every domain, then you can try this:

output = df.drop_duplicates()
output.groupby('domain').size()

output:

    domain
facebook.com    1
google.com      1
twitter.com     2
vk.com          3
dtype: int64

You could also use value_counts, which is slightly less efficient.But the best is Jezrael's answer using nunique:

%timeit df.drop_duplicates().groupby('domain').size()
1000 loops, best of 3: 939 µs per loop
%timeit df.drop_duplicates().domain.value_counts()
1000 loops, best of 3: 1.1 ms per loop
%timeit df.groupby('domain')['ID'].nunique()
1000 loops, best of 3: 440 µs per loop

It is 2018 now, so in ASP.NET Core, there is a straight forward built in function. To delete a cookie try this code:

if(Request.Cookies["aa"] != null)
{
    Response.Cookies.Delete("aa");
}
return View();

I haven't used it, but there's a PECL extension for getting a file's mimetype. The official documentation for it is in the manual.

Depending on your purposes, a file extension can be ok, but it's not incredibly reliable since it's so easily changed.

In Ubuntu:

unzip file.jar -d dir_name_where_extracting

How about this solution

public class BaseActivity extends Activity
{

    static String currentAct = "";

    @Override
    protected void onStart()
    {
        super.onStart();

        if (currentAct.equals(""))
            Toast.makeText(this, "Start", Toast.LENGTH_LONG).show();

        currentAct = getLocalClassName();
    }

    @Override
    protected void onStop()
    {
        super.onStop();

        if (currentAct.equals(getLocalClassName()))
        {
            currentAct = "";
            Toast.makeText(this, "Stop", Toast.LENGTH_LONG).show();
        }
    }
}

All Activity need to extends BaseActivity.

When an activity call another (A->B) then currentAct is not equal getLocalClassName() because the onStart() of the second activity (B) is called before the onStop() of the first (A) (https://developer.android.com/guide/components/activities.html#CoordinatingActivities).

When the user press the home button or change between application will just call onStop() and then currentAct is equal getLocalClassName().

Intresting Question for the programmers. See it will take long long long time to build OS like Windows or Mac but if you want build a simple ones then you can try your best

1. You need to focus on Assembly Language,C and C++. You should be expert in these languages.
2. First read a good book on how OS works[Google it], then read all the info from Wiki OS
3. Search in youtube "How to create your own OS in Assembly Language" watch the video, Eg. Video
4. Download Linux OS source code and compile it yourself and try to modify the code yourself
5. Now you are an experienced OS editor now download Minix and QNX and start developing with them and get their docs from here Minix Doc and QNX Doc

Now you have gained the master degree(Not completely just a little more to go) in creating OS now distribute this knownledge to your freinds and with their help try to create an OS as powerful as Mac, Linux or Windows

Try -webkit-font-smoothing: subpixel-antialiased;

You can use %%:

printf("100%%");

The result is:

100%

In SQL Server 2008 you can use

http://www.sommarskog.se/share_data.html#tableparam

or else simple and same as common execution

CREATE PROCEDURE OrderSummary @MaxQuantity INT OUTPUT AS

SELECT Ord.EmployeeID, SummSales = SUM(OrDet.UnitPrice * OrDet.Quantity)
FROM Orders AS Ord
     JOIN [Order Details] AS OrDet ON (Ord.OrderID = OrDet.OrderID)
GROUP BY Ord.EmployeeID
ORDER BY Ord.EmployeeID

SELECT @MaxQuantity = MAX(Quantity) FROM [Order Details]

RETURN (SELECT SUM(Quantity) FROM [Order Details])
GO

I hopes its help to you

Your code works when run in an script because Python encodes the output to whatever encoding your terminal application is using. If you are piping you must encode it yourself.

A rule of thumb is: Always use Unicode internally. Decode what you receive, and encode what you send.

# -*- coding: utf-8 -*-
print u"åäö".encode('utf-8')

Another didactic example is a Python program to convert between ISO-8859-1 and UTF-8, making everything uppercase in between.

import sys
for line in sys.stdin:
    # Decode what you receive:
    line = line.decode('iso8859-1')

    # Work with Unicode internally:
    line = line.upper()

    # Encode what you send:
    line = line.encode('utf-8')
    sys.stdout.write(line)

Setting the system default encoding is a bad idea, because some modules and libraries you use can rely on the fact it is ASCII. Don't do it.

from datetime import datetime

date = datetime.today().date()

print(date)

If you scale 1600x900 to 1280x720 you have

scale_x = 1280.0/1600
scale_y = 720.0/900

Then you can use it to find button size, and button position

button_width  = 300 * scale_x
button_height = 300 * scale_y

button_x = 1440 * scale_x
button_y = 860  * scale_y

If you scale 1280x720 to 1600x900 you have

scale_x = 1600.0/1280
scale_y = 900.0/720

and rest is the same.

I add .0 to value to make float - otherwise scale_x, scale_y will be rounded to integer - in this example to 0 (zero) (Python 2.x)

You still have to wrap it in an ISERROR, but you could use MATCH() instead of VLOOKUP():

Returns the relative position of an item in an array that matches a specified value in a specified order. Use MATCH instead of one of the LOOKUP functions when you need the position of an item in a range instead of the item itself.

Here's a complete example, assuming you're looking for the word "key" in a range of cells:

=IF(ISERROR(MATCH("key",A5:A16,FALSE)),"missing","found")

The FALSE is necessary to force an exact match, otherwise it will look for the closest value.

You can use JVM args

java -Duser.country=ES -Duser.language=es -Duser.variant=Traditional_WIN

A DTU is a unit of measure for the performance of a service tier and is a summary of several database characteristics. Each service tier has a certain number of DTUs assigned to it as an easy way to compare the performance level of one tier versus another.

Database Throughput Unit (DTU): DTUs provide a way to describe the relative capacity of a performance level of Basic, Standard, and Premium databases. DTUs are based on a blended measure of CPU, memory, reads, and writes. As DTUs increase, the power offered by the performance level increases. For example, a performance level with 5 DTUs has five times more power than a performance level with 1 DTU. A maximum DTU quota applies to each server.

The DTU Quota applies to the server, not the individual databases and each server has a maximum of 1600 DTUs. The DTU% is the percentage of units your particular database is using and it seems that this number can go over 100% of the DTU rating of the service tier (I assume to the limit of the server). This percentage number is designed to help you choose the appropriate service tier.

From down toward the bottom of this announcement:

For example, if your DTU consumption shows a value of 80%, it indicates it is consuming DTU at the rate of 80% of the limit an S2 database would have. If you see values greater than 100% in this view it means that you need a performance tier larger than S2.

As an example, let’s say you see a percentage value of 300%. This tells you that you are using three times more resources than would be available in an S2. To determine a reasonable starting size, compare the DTUs available in an S2 (50 DTUs) with the next higher sizes (P1 = 100 DTUs, or 200% of S2, P2 = 200 DTUs or 400% of S2). Because you are at 300% of S2 you would want to start with a P2 and re-test.

Try this one-

<VirtualHost *:80> 
  ProxyPreserveHost On
  ProxyRequests Off
  ServerName www.adminbackend.example.com
  ServerAlias adminbackend.example.com
  ProxyPass / http://localhost:6000/
  ProxyPassReverse / http://localhost:6000/
  ErrorLog ${APACHE_LOG_DIR}/error.log
  CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost> 

You can refer to socket.io rooms. When you handshaked socket - you can join him to named room, for instance "user.#{userid}".

After that, you can send private message to any client by convenient name, for instance:

io.sockets.in('user.125').emit('new_message', {text: "Hello world"})

In operation above we send "new_message" to user "125".

Range.EntireColumn

Yes! You can use Range.EntireColumn MSDN

dim column : column = 4

dim column_range : set column_range = Sheets(1).Cells(column).EntireColumn

Range("ColumnName:ColumnName")

If you were after a specific column, you could create a hard coded column range with the syntax e.g. Range("D:D").

However, I'd use entire column as it provides more flexibility to change that column at a later time.

Worksheet.Columns

Worksheet.Columns provides Range access to a column within a worksheet. MSDN

If you would like access to the first column of the first sheet. You would call the Columns function on the worksheet.

dim column_range: set column_range = Sheets(1).Columns(1)

The Columns property is also available on any Range MSDN

EntireRow can also be useful if you have a range for a single cell but would like to reach other cells on the row, akin to a LOOKUP

dim id : id = 12345


dim found : set found = Range("A:A").Find(id)

if not found is Nothing then
    'Get the fourth cell from the match
    MsgBox found.EntireRow.Cells(4)
end if

This will help you. :) Follow the next steps,

1. Open the Query Designer

2. Copy Paste the Following code as it is,it will create the Function which convert the String to Int

   CREATE FUNCTION dbo.SplitInts
   (
      @List      VARCHAR(MAX),
      @Delimiter VARCHAR(255)
   )
   RETURNS TABLE
   AS
     RETURN ( SELECT Item = CONVERT(INT, Item) FROM
         ( SELECT Item = x.i.value('(./text())[1]', 'varchar(max)')
           FROM ( SELECT [XML] = CONVERT(XML, '<i>'
           + REPLACE(@List, @Delimiter, '</i><i>') + '</i>').query('.')
             ) AS a CROSS APPLY [XML].nodes('i') AS x(i) ) AS y
         WHERE Item IS NOT NULL
     );
   GO
   

3. Create the Following stored procedure

    CREATE PROCEDURE dbo.sp_DeleteMultipleId
    @List VARCHAR(MAX)
    AS
    BEGIN
         SET NOCOUNT ON;
         DELETE FROM TableName WHERE Id IN( SELECT Id = Item FROM dbo.SplitInts(@List, ',')); 
    END
    GO
   

4. Execute this SP Using exec sp_DeleteId '1,2,3,12' this is a string of Id's which you want to delete,

5. You convert your array to string in C# and pass it as a Stored Procedure parameter

   int[] intarray = { 1, 2, 3, 4, 5 };  
   string[] result = intarray.Select(x=>x.ToString()).ToArray();
   

    

   SqlCommand command = new SqlCommand();
   command.Connection = connection;
   command.CommandText = "sp_DeleteMultipleId";
   command.CommandType = CommandType.StoredProcedure;
   command.Parameters.Add("@Id",SqlDbType.VARCHAR).Value=result ;
   

This will delete multiple rows, All the best

You can reference the image using relative path:

<img src="../images/logo.png">
          __ ______ ________
          |    |       |
          |    |       |___ 3. Get the file named "logo.png"
          |    |
          |    |___ 2. Go inside "images/" subdirectory
          | 
          | 
          |____ 1. Go one level up

Or you can use absolute path: / means that this is an absolute path on the server, So if your server is at https://example.org/, referencing /images/logo.png from any page would point to https://example.org/images/logo.png

<img src="/images/logo.png">
          |______ ________

The * character is not allowed in the path of the URL, but there is no problem using it in the query string:

http://localhost:3286/Search/?q=test*

It's not an encoding issue, the * character has no special meaning in an URL, so it doesn't matter if you URL encode it or not. You would need to encode it using a different scheme, and then decode it.

For example using an arbitrary character as escape character:

query = query.Replace("x", "xxx").Replace("y", "xxy").Replace("*", "xyy");

And decoding:

query = query.Replace("xyy", "*").Replace("xxy", "y").Replace("xxx", "x");

You probably do not need to be making lists and appending them to make your array. You can likely just do it all at once, which is faster since you can use numpy to do your loops instead of doing them yourself in pure python.

To answer your question, as others have said, you cannot access a nested list with two indices like you did. You can if you convert mean_data to an array before not after you try to slice it:

R = np.array(mean_data)[:,0]

instead of

R = np.array(mean_data[:,0])

But, assuming mean_data has a shape nx3, instead of

R = np.array(mean_data)[:,0]
P = np.array(mean_data)[:,1]
Z = np.array(mean_data)[:,2]

You can simply do

A = np.array(mean_data).mean(axis=0)

which averages over the 0th axis and returns a length-n array

But to my original point, I will make up some data to try to illustrate how you can do this without building any lists one item at a time:

Like @Alexis Dufrenoy proposed, the query could be:

SELECT * FROM `table` WHERE find_in_set('sports', interests)>0 OR find_in_set('pub', interests)>0

More information in the manual.

h2.myClass refers to all h2 with class="myClass".

.myClass h2 refers to all h2 that are children of (i.e. nested in) elements with class="myClass".

If you want the h2 in your HTML to appear blue, change the CSS to the following:

.myClass h2 {
    color: blue;
}

If you want to be able to reference that h2 by a class rather than its tag, you should leave the CSS as it is and give the h2 a class in the HTML:

<h2 class="myClass">This header should be BLUE to match the element.class selector</h2>

Use wp_localize_script and pass url there:

wp_localize_script( some_handle, 'admin_url', array('ajax_url' => admin_url( 'admin-ajax.php' ) ) );

then inside js, you can call it by

admin_url.ajax_url 

This could also be a solution:

$yourArray = array('first_key'=> 'First', 2, 3, 4, 5);
$first_key = current(array_flip($yourArray));
echo $first_key;

I have tested it and it works.

Working Code.

I had the same question. This works great in Wordpress!

If you're looking for a solution from Selenium RC, you can use simply

// assuming 'selenium' is a healthy Selenium instance
selenium.type("someLocator", "");

Try this:

System.Windows.Forms.MessageBox.Show("Here's a message!");

In C everything is pass-by-value. The use of pointers gives us the illusion that we are passing by reference because the value of the variable changes. However, if you were to print out the address of the pointer variable, you will see that it doesn't get affected. A copy of the value of the address is passed-in to the function. Below is a snippet illustrating that.

void add_number(int *a) {
    *a = *a + 2;
}

int main(int argc, char *argv[]) {
   int a = 2;

   printf("before pass by reference, a == %i\n", a);
   add_number(&a);
   printf("after  pass by reference, a == %i\n", a);

   printf("before pass by reference, a == %p\n", &a);
   add_number(&a);
   printf("after  pass by reference, a == %p\n", &a);

}

before pass by reference, a == 2
after  pass by reference, a == 4
before pass by reference, a == 0x7fff5cf417ec
after  pass by reference, a == 0x7fff5cf417ec

You could also speed things up with a while loop (see here: http://jsperf.com/javascript-while-vs-for-loops). Also much more terse and legible IMHO:

i = 10
while(i--)
    //- iterate here
    div= i

Binding events from html is NOT recommended. This is recommended way:

document.getElementById('btn').addEventListener('click', function(){
    pay();
    cls();
});

You can do this:

app-routing-modules.ts:

import { NgModule                  }    from '@angular/core';
import { RouterModule, Routes      }    from '@angular/router';
import { PowerBoosterComponent     }    from './component/power-booster.component';


export const routes: Routes = [
  { path:  'pipeexamples',component: PowerBoosterComponent, 
data:{  name:'shubham' } },
    ];
    @NgModule({
      imports: [ RouterModule.forRoot(routes) ],
      exports: [ RouterModule ]
    })
    export class AppRoutingModule {}

In this above route, I want to send data via a pipeexamples path to PowerBoosterComponent.So now I can receive this data in PowerBoosterComponent like this:

power-booster-component.ts

import { Component, OnInit } from '@angular/core';
import { Router, ActivatedRoute, Params, Data } from '@angular/router';

@Component({
  selector: 'power-booster',
  template: `
    <h2>Power Booster</h2>`
})

export class PowerBoosterComponent implements OnInit {
  constructor(
    private route: ActivatedRoute,
    private router: Router

  ) { }
  ngOnInit() {
    //this.route.snapshot.data['name']
    console.log("Data via params: ",this.route.snapshot.data['name']);
  }
}

So you can get the data by this.route.snapshot.data['name'].

In my environment, I just added the two files to class path. And is work fine.

slf4j-jdk14-1.7.25.jar
slf4j-api-1.7.25.jar

jQuery UI draggable and droppable are the two plugins I would use to achieve this effect. As for the insertion marker, I would investigate modifying the div (or container) element that was about to have content dropped into it. It should be possible to modify the border in some way or add a JavaScript/jQuery listener that listens for the hover (element about to be dropped) event and modifies the border or adds an image of the insertion marker in the right place.

The Date constructor (click the link!) accepts the time as long in milliseconds, not seconds. You need to multiply it by 1000 and make sure that you supply it as long.

Date d = new Date(1220227200L * 1000);

This shows here

The ActiveDirectory module for powershell can be installed by adding the RSAT-AD-Powershell feature.

In an elevated powershell window:

Add-WindowsFeature RSAT-AD-PowerShell

or

Enable-WindowsOptionalFeature -FeatureName ActiveDirectory-Powershell -Online -All

If you are using read only input field, you can use ng-value with filter.

for example:

ng-value="price | number:8"

You can try Tsuru. Tsuru is a opensource PaaS inspired in Heroku, and it is already with some products in production at Globo.com(internet arm of the biggest Broadcast Television Company in Brazil)

It manages the entire flow of an application, since the container creation, deploy, routing(with hipache) with many nice features as docker cluster, scaling of units, segregated deploy, etc.

Take a look in our documentation bellow: http://docs.tsuru.io/

Here our post covering our environment: http://blog.tsuru.io/2014/04/04/running-tsuru-in-production-scaling-and-segregating-docker-containers/

Make sure your code is in DOM Ready as pointed by rocket-hazmat

.click()

$('#RootNode').click(function(){
  //do something
});

document.getElementById("RootNode").onclick = function(){//do something}

Use event Delegation/

$(document).on("click", "#RootNode", function(){
   //do something
});

Wrap Code in Dom Ready

$(document).ready(function(){
    $('#RootNode').click(function(){
     //do something
    });
});

I have used this one successfully

System.IO.Path.GetDirectoryName(Process.GetCurrentProcess().MainModule.FileName)

It works even inside linqpad.

Do not forget the . at the end, which indicates end of line

Directly from ngStyle docs:

Expression which evals to an object whose keys are CSS style names and values are corresponding values for those CSS keys.

<div ng-style="{'width': '20px', 'height': '20px', ...}"></div>

So you could do this:

<div ng-style="{'background-color': data.backgroundCol}"></div>

Hope this helps!

I had the same problem and could not find a solution. Mark90 is right there are a lot info.plist files and you should edit the correct. Go to Project, under TARGETS select the project (not the tests), in the tab bar select Info and add the permission under "Custom iOS Target Properties".

The author of this question mentions that it’s usually only after MySQL prints its output that he realises that the wrong query was executed. As noted, in this case, Ctrl-C doesn’t help. However, I’ve noticed that it will abort the current query – if you catch it before any output is printed. For example:

mysql> select * from jos_users, jos_comprofiler;

MySQL gets busy generating the Cartesian Product of the above two tables and you soon notice that MySQL hasn't printed any output to screen (the process state is Sending data) so you type Ctrl-C:

Ctrl-C -- sending "KILL QUERY 113240" to server ...
Ctrl-C -- query aborted.
ERROR 1317 (70100): Query execution was interrupted

Ctrl-C can similarly be used to stop an UPDATE query.

If what your asking is to only show rows that have 1 link for them then you can use the following:

SELECT * FROM posted WHERE link NOT IN 
(SELECT link FROM posted GROUP BY link HAVING COUNT(LINK) > 1)

Again this is assuming that you want to cut out anything that has a duplicate link.

what led me to this page is that I set within a page then the inside of an included page I did the increment

and here is the problem

so to solve such a problem, simply use scope="request" when you declare the variable or the increment

//when you set the variale add scope="request"
<c:set var="nFilters" value="${0}" scope="request"/>
//the increment, it can be happened inside an included page
<c:set var="nFilters" value="${nFilters + 1}"  scope="request" />

hope this saves your time

Phoronix did some benchmarks about this, but it is about a snapshot version of Clang/LLVM from a few months back. The results being that things were more-or-less a push; neither GCC nor Clang is definitively better in all cases.

Since you'd use the latest Clang, it's maybe a little less relevant. Then again, GCC 4.6 is slated to have some major optimizations for Core 2 and i7, apparently.

I figure Clang's faster compilation speed will be nicer for original developers, and then when you push the code out into the world, Linux distro/BSD/etc. end-users will use GCC for the faster binaries.

ElementTree is not too smart about namespaces. You need to give the .find(), findall() and iterfind() methods an explicit namespace dictionary. This is not documented very well:

namespaces = {'owl': 'http://www.w3.org/2002/07/owl#'} # add more as needed

root.findall('owl:Class', namespaces)

Prefixes are only looked up in the namespaces parameter you pass in. This means you can use any namespace prefix you like; the API splits off the owl: part, looks up the corresponding namespace URL in the namespaces dictionary, then changes the search to look for the XPath expression {http://www.w3.org/2002/07/owl}Class instead. You can use the same syntax yourself too of course:

root.findall('{http://www.w3.org/2002/07/owl#}Class')

If you can switch to the lxml library things are better; that library supports the same ElementTree API, but collects namespaces for you in a .nsmap attribute on elements.

To convert the byte[] to string[], simply use the below line.

byte[] fileData; // Some byte array
//Convert byte[] to string[]
var table = (Encoding.Default.GetString(
                 fileData, 
                 0, 
                 fileData.Length - 1)).Split(new string[] { "\r\n", "\r", "\n" },
                                             StringSplitOptions.None);

Just a minor addition: The speed difference between memcpy() and std::copy() can vary quite a bit depending on if optimizations are enabled or disabled. With g++ 6.2.0 and without optimizations memcpy() clearly wins:

Benchmark             Time           CPU Iterations
---------------------------------------------------
bm_memcpy            17 ns         17 ns   40867738
bm_stdcopy           62 ns         62 ns   11176219
bm_stdcopy_n         72 ns         72 ns    9481749

When optimizations are enabled (-O3), everything looks pretty much the same again:

Benchmark             Time           CPU Iterations
---------------------------------------------------
bm_memcpy             3 ns          3 ns  274527617
bm_stdcopy            3 ns          3 ns  272663990
bm_stdcopy_n          3 ns          3 ns  274732792

The bigger the array the less noticeable the effect gets, but even at N=1000 memcpy() is about twice as fast when optimizations aren't enabled.

Source code (requires Google Benchmark):

#include <string.h>
#include <algorithm>
#include <vector>
#include <benchmark/benchmark.h>

constexpr int N = 10;

void bm_memcpy(benchmark::State& state)
{
  std::vector<int> a(N);
  std::vector<int> r(N);

  while (state.KeepRunning())
  {
    memcpy(r.data(), a.data(), N * sizeof(int));
  }
}

void bm_stdcopy(benchmark::State& state)
{
  std::vector<int> a(N);
  std::vector<int> r(N);

  while (state.KeepRunning())
  {
    std::copy(a.begin(), a.end(), r.begin());
  }
}

void bm_stdcopy_n(benchmark::State& state)
{
  std::vector<int> a(N);
  std::vector<int> r(N);

  while (state.KeepRunning())
  {
    std::copy_n(a.begin(), N, r.begin());
  }
}

If you are asking about cache where eclipse stores your project and workspace information right click on your project(s) and choose refresh. Then go to project in the menu on top of the window and click "clean".

This typically does what you need.

If it does not try to remove project from the workspace (just press "delete" on the project and then say that you DO NOT want to remove the sources). Then open project again.

If this does not work too, do the same with the workspace. If this still does not work, perform fresh checkout of your project from source control and create new workspace.

Well, this should work.

you can use:

sort data.txt| uniq -u

this sort data and filter by unique values

With C# 6.0, you can create a dictionary in following way:

var dict = new Dictionary<string, int>
{
    ["one"] = 1,
    ["two"] = 2,
    ["three"] = 3
};

It even works with custom types.

In production code you should be checking the return values of the API calls, but I left that out to make the example clearer.

I have been investigating these ideas and here is my five cents worth. It avoids calling BoundaryNorm as well as specifying norm as an argument to scatter and colorbar. However I have found no way of eliminating the rather long-winded call to matplotlib.colors.LinearSegmentedColormap.from_list.

Some background is that matplotlib provides so-called qualitative colormaps, intended to use with discrete data. Set1, e.g., has 9 easily distinguishable colors, and tab20 could be used for 20 colors. With these maps it could be natural to use their first n colors to color scatter plots with n categories, as the following example does. The example also produces a colorbar with n discrete colors approprately labelled.

import matplotlib, numpy as np, matplotlib.pyplot as plt
n = 5
from_list = matplotlib.colors.LinearSegmentedColormap.from_list
cm = from_list(None, plt.cm.Set1(range(0,n)), n)
x = np.arange(99)
y = x % 11
z = x % n
plt.scatter(x, y, c=z, cmap=cm)
plt.clim(-0.5, n-0.5)
cb = plt.colorbar(ticks=range(0,n), label='Group')
cb.ax.tick_params(length=0)

which produces the image below. The n in the call to Set1 specifies the first n colors of that colormap, and the last n in the call to from_list specifies to construct a map with n colors (the default being 256). In order to set cm as the default colormap with plt.set_cmap, I found it to be necessary to give it a name and register it, viz:

cm = from_list('Set15', plt.cm.Set1(range(0,n)), n)
plt.cm.register_cmap(None, cm)
plt.set_cmap(cm)
...
plt.scatter(x, y, c=z)

You shoud do something like :

print line.split()[0]

I have used the following before:

var my_form = $('#form-id');
var data = {};

$('input:not([type=checkbox]), input[type=checkbox]:selected, select, textarea', my_form).each(
    function() {
        var name = $(this).attr('name');
        var val = $(this).val();

        if (!data.hasOwnProperty(name)) {
            data[name] = new Array;
        }

        data[name].push(val);
    }
);

This is just written from memory, so might contain mistakes, but this should make an object called data that contains the values for all your inputs.

Note that you have to deal with checkboxes in a special way, to avoid getting the values of unchecked checkboxes. The same is probably true of radio inputs.

Also note using arrays for storing the values, as for one input name, you might have values from several inputs (checkboxes in particular).

Create a new instance each time, where each new instance has the correct state, rather than continually modifying the state of the same instance.

Alternately, store an explicitly-made copy of the object (using the hint at this page) at each step, rather than the original.

Install Firebig to see where your error is happening. You could also set up a callback in your ajax call to return your error messages from your PHP. Eg.

error: function(e){
     alert(e);
     }

If you trying to get worked hours with some accuracy, try this (tested in SQL Server 2016)

SELECT DATEDIFF(MINUTE,job_start, job_end)/60.00;

Various DATEDIFF functionalities are:

SELECT DATEDIFF(year,        '2005-12-31 23:59:59.9999999', '2006-01-01 00:00:00.0000000');
SELECT DATEDIFF(quarter,     '2005-12-31 23:59:59.9999999', '2006-01-01 00:00:00.0000000');
SELECT DATEDIFF(month,       '2005-12-31 23:59:59.9999999', '2006-01-01 00:00:00.0000000');
SELECT DATEDIFF(dayofyear,   '2005-12-31 23:59:59.9999999', '2006-01-01 00:00:00.0000000');
SELECT DATEDIFF(day,         '2005-12-31 23:59:59.9999999', '2006-01-01 00:00:00.0000000');
SELECT DATEDIFF(week,        '2005-12-31 23:59:59.9999999', '2006-01-01 00:00:00.0000000');
SELECT DATEDIFF(hour,        '2005-12-31 23:59:59.9999999', '2006-01-01 00:00:00.0000000');
SELECT DATEDIFF(minute,      '2005-12-31 23:59:59.9999999', '2006-01-01 00:00:00.0000000');
SELECT DATEDIFF(second,      '2005-12-31 23:59:59.9999999', '2006-01-01 00:00:00.0000000');

Solved myself. Done some small structural changes also. Route from Component1 to Component2 is done by a single <router-outlet>. Component2 to Comonent3 and Component4 is done by multiple <router-outlet name= "xxxxx"> The resulting contents are :

Component1.html

<nav>
    <a routerLink="/two" class="dash-item">Go to 2</a>
</nav>
    <router-outlet></router-outlet>

Component2.html

 <a [routerLink]="['/two', {outlets: {'nameThree': ['three']}}]">In Two...Go to 3 ...       </a>
 <a [routerLink]="['/two', {outlets: {'nameFour': ['four']}}]">   In Two...Go to 4 ...</a>

 <router-outlet name="nameThree"></router-outlet>
 <router-outlet name="nameFour"></router-outlet>

The '/two' represents the parent component and ['three']and ['four'] represents the link to the respective children of component2 . Component3.html and Component4.html are the same as in the question.

router.module.ts

const routes: Routes = [
{
    path: '',
    redirectTo: 'one',
    pathMatch: 'full'
},
{
    path: 'two',
    component: ClassTwo, children: [

        {
            path: 'three',
            component: ClassThree,
            outlet: 'nameThree'
        },
        {
            path: 'four',
            component: ClassFour,
            outlet: 'nameFour'
        }
    ]
},];

The below code worked for me :)

window.open('your current page URL', '_self', '');
window.close();

Very nice example from Matt, I fixed the typo and also pyqt4.8 is common now so I removed the dummy class as well and added an example for the dataReady signal

# -*- coding: utf-8 -*-
import sys
from PyQt4 import QtCore, QtGui
from PyQt4.QtCore import Qt


# very testable class (hint: you can use mock.Mock for the signals)
class Worker(QtCore.QObject):
    finished = QtCore.pyqtSignal()
    dataReady = QtCore.pyqtSignal(list, dict)

    @QtCore.pyqtSlot()
    def processA(self):
        print "Worker.processA()"
        self.finished.emit()

    @QtCore.pyqtSlot(str, list, list)
    def processB(self, foo, bar=None, baz=None):
        print "Worker.processB()"
        for thing in bar:
            # lots of processing...
            self.dataReady.emit(['dummy', 'data'], {'dummy': ['data']})
        self.finished.emit()


def onDataReady(aList, aDict):
    print 'onDataReady'
    print repr(aList)
    print repr(aDict)


app = QtGui.QApplication(sys.argv)

thread = QtCore.QThread()  # no parent!
obj = Worker()  # no parent!
obj.dataReady.connect(onDataReady)

obj.moveToThread(thread)

# if you want the thread to stop after the worker is done
# you can always call thread.start() again later
obj.finished.connect(thread.quit)

# one way to do it is to start processing as soon as the thread starts
# this is okay in some cases... but makes it harder to send data to
# the worker object from the main gui thread.  As you can see I'm calling
# processA() which takes no arguments
thread.started.connect(obj.processA)
thread.finished.connect(app.exit)

thread.start()

# another way to do it, which is a bit fancier, allows you to talk back and
# forth with the object in a thread safe way by communicating through signals
# and slots (now that the thread is running I can start calling methods on
# the worker object)
QtCore.QMetaObject.invokeMethod(obj, 'processB', Qt.QueuedConnection,
                                QtCore.Q_ARG(str, "Hello World!"),
                                QtCore.Q_ARG(list, ["args", 0, 1]),
                                QtCore.Q_ARG(list, []))

# that looks a bit scary, but its a totally ok thing to do in Qt,
# we're simply using the system that Signals and Slots are built on top of,
# the QMetaObject, to make it act like we safely emitted a signal for
# the worker thread to pick up when its event loop resumes (so if its doing
# a bunch of work you can call this method 10 times and it will just queue
# up the calls.  Note: PyQt > 4.6 will not allow you to pass in a None
# instead of an empty list, it has stricter type checking

app.exec_()

function checkForm(& $fields){
    foreach($fields as $field){
        if($field['required'] && strlen($_POST[$field['name']]) <= 0){
            $fields[$field]['value'] = "Some error";
        }
    }
    return $fields;
}

This is what I would Suggest pass by reference

Is it a console program, running in Windows? If so, run it from a console you've already opened. i.e. run "cmd", then change to your directory that has the .exe in it (using the cd command), then type in the exe name. Your console window will stay open.

What about this?

var Restaurant = (function() {

 var _id = 0;
 var privateVars = [];

 function Restaurant(name) {
     this.id = ++_id;
     this.name = name;
     privateVars[this.id] = {
         cooked: []
     };
 }

 Restaurant.prototype.cook = function (food) {
     privateVars[this.id].cooked.push(food);
 }

 return Restaurant;

})();

Private variable lookup is impossible outside of the scope of the immediate function. There is no duplication of functions, saving memory.

The downside is that the lookup of private variables is clunky privateVars[this.id].cooked is ridiculous to type. There is also an extra "id" variable.

A big thank you to @Musa and here is a neat function that converts the data to a base64 string. This may come handy to you when handling a binary file (pdf, png, jpeg, docx, ...) file in a WebView that gets the binary file but you need to transfer the file's data safely into your app.

// runs a get/post on url with post variables, where:
// url ... your url
// post ... {'key1':'value1', 'key2':'value2', ...}
//          set to null if you need a GET instead of POST req
// done ... function(t) called when request returns
function getFile(url, post, done)
{
   var postEnc, method;
   if (post == null)
   {
      postEnc = '';
      method = 'GET';
   }
   else
   {
      method = 'POST';
      postEnc = new FormData();
      for(var i in post)
         postEnc.append(i, post[i]);
   }
   var xhr = new XMLHttpRequest();
   xhr.onreadystatechange = function() {
      if (this.readyState == 4 && this.status == 200)
      {
         var res = this.response;
         var reader = new window.FileReader();
         reader.readAsDataURL(res); 
         reader.onloadend = function() { done(reader.result.split('base64,')[1]); }
      }
   }
   xhr.open(method, url);
   xhr.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
   xhr.send('fname=Henry&lname=Ford');
   xhr.responseType = 'blob';
   xhr.send(postEnc);
}

The presence of the n option attached to the -k5 causes the global -r option to be ignored for that field. You have to specify both n and r at the same level (globally or locally).

sort -t $'\t' -k5,5rn

or

sort -rn -t $'\t' -k5,5

This works fine for me

1. Run Command Prompt as Administrator

2. Navigate to the folder containing nodejs (eg. C:\Program Files\nodejs)

3. Run Powershell -ExecutionPolicy Unrestricted

4. Run npm-windows-upgrade

5. This will show list of versions available to install. Just select your desired version by moving up/down key & Press Enter.
   
   This'll update your npm
6. To check the current version of npm

   Run npm --version
