You will not be able to do that. You can download apps again to the same userid account on different devices, but you cannot transfer those licenses to other userids.

There is no way to do this programatically - I don't think you can do that practically (except for trying to call customer support at the Play Store).

For comparison, I tried transfering a 299GB ntfs disk image from an i5 laptop running Raring Ringtail Ubuntu alpha 2 live cd to an i7 desktop running Ubuntu 12.04.1. Reported speeds:

over wifi + powerline: scp: 5MB/sec (40 Mbit/sec)

over gigabit ethernet + netgear G5608 v3:

scp: 44MB/sec

sftp: 47MB/sec

sftp -C: 13MB/sec

So, over a good gigabit link, sftp is slightly faster than scp, 2010-era fast CPUs seem fast enough to encrypt, but compression isn't a win in all cases.

Over a bad gigabit ethernet link, though, I've had sftp far outperform scp. Something about scp being very chatty, see "scp UNBELIEVABLY slow" on comp.security.ssh from 2008: https://groups.google.com/forum/?fromgroups=#!topic/comp.security.ssh/ldPV3msFFQw http://fixunix.com/ssh/368694-scp-unbelievably-slow.html

This is very easy by import repository feature Login to github.com,

Side of profile picture you will find + button click on that then there will be option to import repository. you will find page like this. Your old repository’s clone URL is required which is gitlab repo url in your case. then select Owner and then type name for this repo and click to begin import button.

You could use the CSS calc parameter to calculate the height dynamically like so:

.dynamic-height {_x000D_
   color: #000;_x000D_
   font-size: 12px;_x000D_
   margin-top: calc(100% - 10px);_x000D_
   text-align: left;_x000D_
}

<div class='dynamic-height'>_x000D_
    <p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. Aenean massa. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Donec quam felis, ultricies nec, pellentesque eu, pretium quis, sem.</p>_x000D_
</div>

DataGridViewColumn column0 = dataGridViewGroup.Columns[0];
DataGridViewColumn column1 = dataGridViewGroup.Columns[1];
column1.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleRight;
column1.Width = 120;

If you're using Bash you could also use one of the following commands:

printf '%(%Y%m%d%H%M%S)T'       # prints the current time
printf '%(%Y%m%d%H%M%S)T' -1    # same as above
printf '%(%Y%m%d%H%M%S)T' -2    # prints the time the shell was invoked

You can use the Option -v varname to store the result in $varname instead of printing it to stdout:

printf -v varname '%(%Y%m%d%H%M%S)T'

While the date command will always be executed in a subshell (i.e. in a separate process) printf is a builtin command and will therefore be faster.

In Scala,

val ticks = "'([^']*)'".r

ticks findFirstIn mydata match {
    case Some(ticks(inside)) => println(inside)
    case _ => println("nothing")
}

for (ticks(inside) <- ticks findAllIn mydata) println(inside) // multiple matches

val Some(ticks(inside)) = ticks findFirstIn mydata // may throw exception

val ticks = ".*'([^']*)'.*".r    
val ticks(inside) = mydata // safe, shorter, only gets the first set of ticks

If you need apache Listen port other than 80, you should add next file under ubuntu

"/etc/apache2/ports.conf"

the list of Listen ports

Listen 80
Listen 81
Listen 82

After you have to go on your Virtual hosts conf file and define next

<VirtualHost *:80>
  #...v host 1
</VirtualHost>


<VirtualHost *:81>
  #...host 2
</VirtualHost>


<VirtualHost *:82>
  #...host 3
</VirtualHost>

One good example of when to use something like this is with Java Simple Serial Connector, accessing serial ports. Typically you'll write something to the port, and asyncronously, on another thread, the device will respond on a SerialPortEventListener. Typically, you'll want to pause after writing to the port to wait for the response. Handling the thread locks for this scenario manually is extremely tricky, but using Countdownlatch is easy. Before you go thinking you can do it another way, be careful about race conditions you never thought of!!

Pseudocode:

CountDownLatch latch;
void writeData() { 
   latch = new CountDownLatch(1);
   serialPort.writeBytes(sb.toString().getBytes())
   try {
      latch.await(4, TimeUnit.SECONDS);
    } catch (InterruptedException e) {
   }
}
class SerialPortReader implements SerialPortEventListener {
    public void serialEvent(SerialPortEvent event) {
        if(event.isRXCHAR()){//If data is available
            byte buffer[] = serialPort.readBytes(event.getEventValue());
            latch.countDown();
         }
     }
}

For documentation purpose, it's better to list the string values that are legal:

size: PropTypes.oneOfType([
    PropTypes.number,
    PropTypes.oneOf([ 'SMALL', 'LARGE' ]),
]),

Vertically centering a div inside another div

#outerDiv{_x000D_
  width: 500px;_x000D_
  height: 500px;_x000D_
  position:relative;_x000D_
  _x000D_
  background-color: lightgrey;  _x000D_
}_x000D_
_x000D_
#innerDiv{_x000D_
  width: 284px;_x000D_
  height: 290px;_x000D_
  _x000D_
  position: absolute;_x000D_
  top: 50%;_x000D_
  left: 50%;_x000D_
  transform: translate(-50%, -50%);_x000D_
  -ms-transform: translate(-50%, -50%); /* IE 9 */_x000D_
  -webkit-transform: translate(-50%, -50%); /* Chrome, Safari, Opera */ _x000D_
  _x000D_
  background-color: grey;_x000D_
}

<div id="outerDiv">_x000D_
  <div id="innerDiv"></div>_x000D_
</div>

One other way around this is to use @Mock annotation instead. Doesn't work in all cases, but looks much sexier :)

Here's an example:

@RunWith(MockitoJUnitRunner.class)
public class FooTests {

    @Mock
    public Foo<Bar> fooMock;

    @Test
    public void testFoo() {
        when(fooMock.getValue()).thenReturn(new Bar());
    }
}

The MockitoJUnitRunner initializes the fields annotated with @Mock.

text-align aligns text and other inline content. It doesn't align block element children.

To do that, you want to give the element you want aligned a width, with ‘auto’ left and right margins. This is the standards-compliant way that works everywhere except IE5.x.

<div style="width: 50%; margin: 0 auto;">Hello</div>

For this to work in IE6, you need to make sure Standards Mode is on by using a suitable DOCTYPE.

If you really need to support IE5/Quirks Mode, which these days you shouldn't really, it is possible to combine the two different approaches to centering:

<div style="text-align: center">
    <div style="width: 50%; margin: 0 auto; text-align: left">Hello</div>
</div>

(Obviously, styles are best put inside a stylesheet, but the inline version is illustrative.)

you can use solutions without adding "Access-Control-Allow-Origin": "*", if your server is already using Proxy gateway this issue will not happen because the front and backend will be route in the same IP and port in client side but for development, you need one of this three solution if you don't need extra code 1- simulate the real environment by using a proxy server and configure the front and backend in the same port

2- if you using Chrome you can use the extension called Allow-Control-Allow-Origin: * it will help you to avoid this problem

3- you can use the code but some browsers versions may not support that so try to use one of the previous solutions

the best solution is using a proxy like ngnix its easy to configure and it will simulate the real situation of the production deployment

This is with HPUX, if the content of the files has space between words, use this:

egrep "[[:space:]]ABC\.log[[:space:]]" a.tmp

You can as long as

• The value is unique
• No existing foreign keys are violated

A solution working with map built-in fonction !

arg_names = ['command' ,'operation', 'parameter']
args = map(None, arg_names, sys.argv)
args = {k:v for (k,v) in args}

Then you just have to call your parameters like this:

if args['operation'] == "division":
    if not args['parameter']:
        ...
    if args['parameter'] == "euclidian":
        ...

There's a proposed feature which you could use for arbitrarily shaped drop shadows. You could see it here, courtesy of Lea Verou:

Browser support is minimal, though.

To multiply, use mult for signed multiplication and multu for unsigned multiplication. Note that the result of the multiplication of two 32-bit numbers yields a 64-number. If you want the result back in $v0 that means that you assume the result will fit in 32 bits.

The 32 most significant bits will be held in the HI special register (accessible by mfhi instruction) and the 32 least significant bits will be held in the LO special register (accessible by the mflo instruction):

E.g.:

li $a0, 5
li $a1, 3
mult $a0, $a1
mfhi $a2 # 32 most significant bits of multiplication to $a2
mflo $v0 # 32 least significant bits of multiplication to $v0

To divide, use div for signed division and divu for unsigned division. In this case, the HI special register will hold the remainder and the LO special register will hold the quotient of the division.

E.g.:

div $a0, $a1
mfhi $a2 # remainder to $a2
mflo $v0 # quotient to $v0

Example: Read json from file

/* test.json */
{
   "appDesc": {
      "description": "SomeDescription",
      "message": "SomeMessage"
   },
   "appName": {
      "description": "Home",
      "message": "Welcome",
      "imp":["awesome","best","good"]
   }
}


void readJson()
   {
      QString val;
      QFile file;
      file.setFileName("test.json");
      file.open(QIODevice::ReadOnly | QIODevice::Text);
      val = file.readAll();
      file.close();
      qWarning() << val;
      QJsonDocument d = QJsonDocument::fromJson(val.toUtf8());
      QJsonObject sett2 = d.object();
      QJsonValue value = sett2.value(QString("appName"));
      qWarning() << value;
      QJsonObject item = value.toObject();
      qWarning() << tr("QJsonObject of description: ") << item;

      /* in case of string value get value and convert into string*/
      qWarning() << tr("QJsonObject[appName] of description: ") << item["description"];
      QJsonValue subobj = item["description"];
      qWarning() << subobj.toString();

      /* in case of array get array and convert into string*/
      qWarning() << tr("QJsonObject[appName] of value: ") << item["imp"];
      QJsonArray test = item["imp"].toArray();
      qWarning() << test[1].toString();
   }

OUTPUT

QJsonValue(object, QJsonObject({"description": "Home","imp": ["awesome","best","good"],"message": "YouTube"}) )

Example: Read json from string

Assign json to string as below and use the readJson() function shown before:

val =   
'  {

Based on a feature mentioned in this answer to another question I have found a very generally applicable solution for placing labels on a bar chart.

Other solutions unfortunately do not work in many cases, because the spacing between label and bar is either given in absolute units of the bars or is scaled by the height of the bar. The former only works for a narrow range of values and the latter gives inconsistent spacing within one plot. Neither works well with logarithmic axes.

The solution I propose works independent of scale (i.e. for small and large numbers) and even correctly places labels for negative values and with logarithmic scales because it uses the visual unit points for offsets.

I have added a negative number to showcase the correct placement of labels in such a case.

The value of the height of each bar is used as a label for it. Other labels can easily be used with Simon's for rect, label in zip(rects, labels) snippet.

# In my original code I create a series and run on that,
# so for consistency I create a series from the list.
freq_series = pd.Series.from_array(frequencies)

x_labels = [108300.0, 110540.0, 112780.0, 115020.0, 117260.0, 119500.0,

                                        # positive and negative values.


# Call the function above. All the magic happens there.
add_value_labels(ax)

plt.savefig("image.png")

Edit: I have extracted the relevant functionality in a function, as suggested by barnhillec.

This produces the following output:

And with logarithmic scale (and some adjustment to the input data to showcase logarithmic scaling), this is the result:

use sys module

import sys
sys.exit()

The simplest way is using libraries like google-http-java-client but if you want parse the JSON response by yourself you can do that in a multiple ways, you can use org.json, json-simple, Gson, minimal-json, jackson-mapper-asl (from 1.x)... etc

A set of simple examples:

Using Gson:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;

public class Gson {

    public static void main(String[] args) {
    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);
            String json = EntityUtils.toString(result.getEntity(), "UTF-8");

            com.google.gson.Gson gson = new com.google.gson.Gson();
            Response respuesta = gson.fromJson(json, Response.class);

            System.out.println(respuesta.getExample());
            System.out.println(respuesta.getFr());

        } catch (IOException ex) {
        }
        return null;
    }

    public class Response{

        private String example;
        private String fr;

        public String getExample() {
            return example;
        }
        public void setExample(String example) {
            this.example = example;
        }
        public String getFr() {
            return fr;
        }
        public void setFr(String fr) {
            this.fr = fr;
        }
    }
}

Using json-simple:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;

public class JsonSimple {

    public static void main(String[] args) {

    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);

            String json = EntityUtils.toString(result.getEntity(), "UTF-8");
            try {
                JSONParser parser = new JSONParser();
                Object resultObject = parser.parse(json);

                if (resultObject instanceof JSONArray) {
                    JSONArray array=(JSONArray)resultObject;
                    for (Object object : array) {
                        JSONObject obj =(JSONObject)object;
                        System.out.println(obj.get("example"));
                        System.out.println(obj.get("fr"));
                    }

                }else if (resultObject instanceof JSONObject) {
                    JSONObject obj =(JSONObject)resultObject;
                    System.out.println(obj.get("example"));
                    System.out.println(obj.get("fr"));
                }

            } catch (Exception e) {
                // TODO: handle exception
            }

        } catch (IOException ex) {
        }
        return null;
    }
}

etc...

No. The first returns a DOM element, or null, whereas the second always returns a jQuery object. The jQuery object will be empty if no element with the id of contents was matched.

The DOM element returned by document.getElementById('contents') allows you to do things such as change the .innerHTML (or .value) etc, however you'll need to use jQuery methods on the jQuery Object.

var contents = $('#contents').get(0);

Is more equivilent, however if no element with the id of contents is matched, document.getElementById('contents') will return null, but $('#contents').get(0) will return undefined.

One benefit on using the jQuery object is that you won't get any errors if no elements were returned, as an object is always returned. However you will get errors if you try to perform operations on the null returned by document.getElementById

The linefeed character \n is not the line separator in certain operating systems (such as windows, where it's "\r\n") - my suggestion is that you use \r\n instead, then it'll both see the line-break with only \n and \r\n, I've never had any problems using it.

Also, you should look into using a StringBuilder instead of concatenating the String in the while-loop at BookCatalog.toString(), it is a lot more effective. For instance:

public String toString() {
        BookNode current = front;
        StringBuilder sb = new StringBuilder();
        while (current!=null){
            sb.append(current.getData().toString()+"\r\n ");
            current = current.getNext();
        }
        return sb.toString();
}

File mode, write and binary. Since you are writing a .jpg file, it looks fine.

But if you supposed to read that jpg file you need to use 'rb'

More info

On Windows, 'b' appended to the mode opens the file in binary mode, so there are also modes like 'rb', 'wb', and 'r+b'. Python on Windows makes a distinction between text and binary files; the end-of-line characters in text files are automatically altered slightly when data is read or written. This behind-the-scenes modification to file data is fine for ASCII text files, but it’ll corrupt binary data like that in JPEG or EXE files.

When reading the strtok documentation, I see you need to pass in a NULL pointer after the first "initializing" call. Maybe you didn't do that. Just a guess of course.

When you want one element placed at the bottom other element you use this code in CSS. It is used for floats.

If you float content you can float left or right... so in a common layout you might have a left nav, a content div and a footer.

To ensure the footer stays below both of these floats (if you have floated left and right) then you put the footer as clear: both.

This way it will stay below both floats.

(If you are only clearing left then you only really need to clear: left;.)

Go through this tutorial:

For okhttp3 this has changed a bit.

Now you set up the times using the builder, and not setters, like this:

OkHttpClient client = new OkHttpClient.Builder()
        .connectTimeout(10, TimeUnit.SECONDS)
        .writeTimeout(10, TimeUnit.SECONDS)
        .readTimeout(30, TimeUnit.SECONDS)
        .build();

More info can be found in their wiki: https://github.com/square/okhttp/blob/b3dcb9b1871325248fba917458658628c44ce8a3/docs/recipes.md#timeouts-kt-java

Let me explain with an example and you would be able to see how it works.

Assuming you have the following table DIM_EQUIPMENT:

VIN         MAKE    MODEL   YEAR    COLOR
-----------------------------------------
1234ASDF    Ford    Taurus  2008    White
1234JKLM    Chevy   Truck   2005    Green
5678ASDF    Ford    Mustang 2008    Yellow

Run below SQL

SELECT VIN,
  MAKE,
  MODEL,
  YEAR,
  COLOR ,
  COUNT(*) OVER (PARTITION BY YEAR) AS COUNT2
FROM DIM_EQUIPMENT

The result would be as below

VIN         MAKE    MODEL   YEAR    COLOR     COUNT2
 ----------------------------------------------  
1234JKLM    Chevy   Truck   2005    Green     1
5678ASDF    Ford    Mustang 2008    Yellow    2
1234ASDF    Ford    Taurus  2008    White     2

See what happened.

You are able to count without Group By on YEAR and Match with ROW.

Another Interesting WAY to get same result if as below using WITH Clause, WITH works as in-line VIEW and can simplify the query especially complex ones, which is not the case here though since I am just trying to show usage

 WITH EQ AS
  ( SELECT YEAR AS YEAR2, COUNT(*) AS COUNT2 FROM DIM_EQUIPMENT GROUP BY YEAR
  )
SELECT VIN,
  MAKE,
  MODEL,
  YEAR,
  COLOR,
  COUNT2
FROM DIM_EQUIPMENT,
  EQ
WHERE EQ.YEAR2=DIM_EQUIPMENT.YEAR;

Something like this works:

input + label::after {_x000D_
  content: 'click my input';_x000D_
  color: black;_x000D_
}_x000D_
_x000D_
input:focus + label::after {_x000D_
  content: 'not valid yet';_x000D_
  color: red;_x000D_
}_x000D_
_x000D_
input:valid + label::after {_x000D_
  content: 'looks good';_x000D_
  color: green;_x000D_
}

<input id="input" type="number" required />_x000D_
<label for="input"></label>

Then add some floats or positioning to order stuff.

To add a new file in SVN

svn add file_name
svn commit -m "text about changes..."

To add a new file in a directory in SVN

svn add directory_name/file_name
svn commit -m "text about changes"

To add all new files in a directory with some targets (files) are already versioned (added):

svn add directory_name/*
svn commit -m "text about changes"

A) For a cheap comparison / arithmetics dummy use math.inf. Or math.nan, which compares FALSE in any direction (including nan == nan) except identity check (is) and renders any arithmetics (like nan - nan) nan. Or a reasonably high real integer number according to your use case (e.g. sys.maxsize). For a bitmask dummy (e.g. in mybits & bitmask) use -1.

B) To get the platform primitive maximum signed long int (or long long):

>>> 256 ** sys.int_info.sizeof_digit // 2 - 1  # Python’s internal primitive
2147483647
>>> 256 ** ctypes.sizeof(ctypes.c_long) // 2 - 1  # CPython
2147483647
>>> 256 ** ctypes.sizeof(ctypes.c_longlong) // 2 - 1  # CPython
9223372036854775807
>>> 2**63 - 1  # Java / JPython primitive long
9223372036854775807

C) The maximum Python integer could be estimated by a long running loop teasing for a memory overflow (try 256**int(8e9) - can be stopped by KeyboardInterrupt). But it cannot not be used reasonably, because its representation already consumes all the memory and its much greater than sys.float_info.max.

Adding style="width:100%;max-width:640px" to the image tag will scale it up to the viewport width, i.e. for larger windows it will look fixed width.

You could follow maven's standard project layout. You don't have to actually use maven, but it would make the transition easier in the future (if necessary). Plus, other developers will be used to seeing that layout, since many open source projects are layed out this way,

I'm surprised no one mentioned the HTML entities   and   which produce horizontal white space equivalent to the characters n and m, respectively. If you want to accumulate horizontal white space quickly, those are more efficient than  .

1. no space
2.   
3.  
4.  

Along with <space> and  , these are the five entities HTML provides for horizontal white space.

Note that except for  , all entities allow breaking. Whatever text surrounds them will wrap to a new line if it would otherwise extend beyond the container boundary. With   it would wrap to a new line as a block even if the text before   could fit on the previous line.

Depending on your use case, that may be desired or undesired. For me, unless I'm dealing with things like names (John Doe), addresses or references (see eq. 5), breaking as a block is usually undesired.

Dumping an ActiveRecord object to JSON (in the Rails console):

pp User.first.as_json

# => {
 "id" => 1,
 "first_name" => "Polar",
 "last_name" => "Bear"
}

BE CAREFUL with those other answers as they will not play properly with bodyParser if you're looking to also support json, urlencoded, etc. To get it to work with bodyParser you should condition your handler to only register on the Content-Type header(s) you care about, just like bodyParser itself does.

To get the raw body content of a request with Content-Type: "text/plain" into req.rawBody you can do:

app.use(function(req, res, next) {
  var contentType = req.headers['content-type'] || ''
    , mime = contentType.split(';')[0];

  if (mime != 'text/plain') {
    return next();
  }

  var data = '';
  req.setEncoding('utf8');
  req.on('data', function(chunk) {
    data += chunk;
  });
  req.on('end', function() {
    req.rawBody = data;
    next();
  });
});

Just getting the name from scm.branches is not enough if you've used a build parameter as a branch specifier, e.g. ${BRANCH}. You need to expand that string into a real name:

scm.branches.first().getExpandedName(env.getEnvironment())

Note that getEnvironment() must be an explicit getter otherwise env will look up for an environment variable called environment.

Don't forget that you need to approve those methods to make them accessible from the sandbox.

What I found useful and I found on one link above is this FQL query where you ask for likes, total, share and click count of one link by looking at the link_stat table

https://graph.facebook.com/fql?q=SELECT%20like_count,%20total_count,%20share_count,%20click_count,%20comment_count%20FROM%20link_stat%20WHERE%20url%20=%20%22http://google.com%22

That will output something like this:

{
    data: [
        {
             like_count: 3440162,
             total_count: 13226503,
             share_count: 7732740,
             click_count: 265614,
             comment_count: 2053601
         }
    ]
}

This is for SQL Server:

ALTER TABLE TableName
ADD ColumnName (type) -- NULL OR NOT NULL
DEFAULT (default value)
WITH VALUES

Example:

ALTER TABLE Activities
ADD status int NOT NULL DEFAULT (0)
WITH VALUES

If you want to add constraints then:

ALTER TABLE Table_1
ADD row3 int NOT NULL
CONSTRAINT CONSTRAINT_NAME DEFAULT (0)
WITH VALUES

You can use Spacers if all you want is a little bit of spacing between items in a row. The example below centers 2 Text widgets within a row with some spacing between them.

Spacer creates an adjustable, empty spacer that can be used to tune the spacing between widgets in a Flex container, like Row or Column.

In a row, if we want to put space between two widgets such that it occupies all remaining space.

    widget = Row (
    children: <Widget>[
      Spacer(flex: 20),
      Text(
        "Item #1",
      ),
      Spacer(),  // Defaults to flex: 1
      Text(
        "Item #2",
      ),
      Spacer(flex: 20),
    ]
  );

Just typing this single line would give you a json array ,

echo json_encode($array);

Normally you use json_encode to read data from an ios or android app. so make sure you do not echo anything else other than the accurate json array.

Here is a DB2 Stored Procidure that receive a parameter

If your project's source code has import statements that reference classes that are in widget.jar, you should add the jar to your projects Compile-time Libraries. (The jar widget.jar will automatically be added to your project's Run-time Libraries). That corresponds to (1).

If your source code has imports for classes in some other jar and the source code for those classes has import statements that reference classes in widget.jar, you should add widget.jar to the Run-time libraries list. That corresponds to (2).

You can add the jars directly to the Libraries list in the project properties. You can also create a Library that contains the jar file and then include that Library in the Compile-time or Run-time Libraries list.

If you create a NetBeans Library for widget.jar, you can also associate source code for the jar's content and Javadoc for the APIs defined in widget.jar. This additional information about widget.jar will be used by NetBeans as you debug code. It will also be used to provide addition information when you use code completion in the editor.

You should avoid using Tools >> Java Platform to add a jar to a project. That dialog allows you to modify the classpath that is used to compile and run all projects that use the Java Platform that you create. That may be useful at times but hides your project's dependency on widget.jar almost completely.

Sort normally and use Collections.reverse();

Had the same problem while working with bootstrap modal. I had accidentally set the z-index for .ui-datepicker using !important which overrides the date picker z-index css attribute on the element. Removing !important worked.

v is a query parameter, technically you need to consider cases ala: http://www.youtube.com/watch?p=DB852818BF378DAC&v=1q-k-uN73Gk

In .NET I would recommend to use System.Web.HttpUtility.ParseQueryString

HttpUtility.ParseQueryString(url)["v"];

And you don't even need to check the key, as it will return null if the key is not in the collection.

Don't use CREATE TYPE to return a polymorphic result. Use and abuse the RECORD type instead. Check it out:

CREATE FUNCTION test_ret(a TEXT, b TEXT) RETURNS RECORD AS $$
DECLARE 
  ret RECORD;
BEGIN
  -- Arbitrary expression to change the first parameter
  IF LENGTH(a) < LENGTH(b) THEN
      SELECT TRUE, a || b, 'a shorter than b' INTO ret;
  ELSE
      SELECT FALSE, b || a INTO ret;
  END IF;
RETURN ret;
END;$$ LANGUAGE plpgsql;

Pay attention to the fact that it can optionally return two or three columns depending on the input.

test=> SELECT test_ret('foo','barbaz');
             test_ret             
----------------------------------
 (t,foobarbaz,"a shorter than b")
(1 row)

test=> SELECT test_ret('barbaz','foo');
             test_ret             
----------------------------------
 (f,foobarbaz)
(1 row)

This does wreak havoc on code, so do use a consistent number of columns, but it's ridiculously handy for returning optional error messages with the first parameter returning the success of the operation. Rewritten using a consistent number of columns:

CREATE FUNCTION test_ret(a TEXT, b TEXT) RETURNS RECORD AS $$
DECLARE 
  ret RECORD;
BEGIN
  -- Note the CASTING being done for the 2nd and 3rd elements of the RECORD
  IF LENGTH(a) < LENGTH(b) THEN
      ret := (TRUE, (a || b)::TEXT, 'a shorter than b'::TEXT);
  ELSE
      ret := (FALSE, (b || a)::TEXT, NULL::TEXT);
   END IF;
RETURN ret;
END;$$ LANGUAGE plpgsql;

Almost to epic hotness:

test=> SELECT test_ret('foobar','bar');
   test_ret    
----------------
 (f,barfoobar,)
(1 row)

test=> SELECT test_ret('foo','barbaz');
             test_ret             
----------------------------------
 (t,foobarbaz,"a shorter than b")
(1 row)

But how do you split that out in to multiple rows so that your ORM layer of choice can convert the values in to your language of choice's native data types? The hotness:

test=> SELECT a, b, c FROM test_ret('foo','barbaz') AS (a BOOL, b TEXT, c TEXT);
 a |     b     |        c         
---+-----------+------------------
 t | foobarbaz | a shorter than b
(1 row)

test=> SELECT a, b, c FROM test_ret('foobar','bar') AS (a BOOL, b TEXT, c TEXT);
 a |     b     | c 
---+-----------+---
 f | barfoobar | 
(1 row)

This is one of the coolest and most underused features in PostgreSQL. Please spread the word.

Here's a slightly modified version of @David Brainer-Bankers answer that sorts alphabetically by string, or numerically by number, and ensures that words beginning with Capital letters don't sort above words starting with a lower case letter (e.g "apple,Early" would be displayed in that order).

function sortByKey(array, key) {
    return array.sort(function(a, b) {
        var x = a[key];
        var y = b[key];

        if (typeof x == "string")
        {
            x = (""+x).toLowerCase(); 
        }
        if (typeof y == "string")
        {
            y = (""+y).toLowerCase();
        }

        return ((x < y) ? -1 : ((x > y) ? 1 : 0));
    });
}

Try using the EXCEPT syntax.
Something like this:

   SELECT * 
    FROM   clientDetails 
    EXCEPT 
    (SELECT TOP (numbers of rows - how many rows you want) * 
     FROM   clientDetails) 

Use machinepack-datetime to format the datetime.

tutorialSchema.virtual('createdOn').get(function () {
    const DateTime = require('machinepack-datetime');
    let timeAgoString = "";
    try {
        timeAgoString = DateTime.timeFrom({
            toWhen: DateTime.parse({
                datetime: this.createdAt
            }).execSync(),
            fromWhen: new Date().getTime()
        }).execSync();
    } catch(err) {
        console.log('error getting createdon', err);
    }
    return timeAgoString; // a second ago
});

Machine pack is great with clear API unlike express or general Javascript world.

This is a very simple to create file in git bash at first write touch then file name with extension

for example

touch filename.extension

Try python-request or python-grab

int length;
    Scanner input = new Scanner(System.in);
    System.out.println("How many numbers you wanna enter?");
    length = input.nextInt();
    System.out.println("Enter " + length + " numbers, one by one...");
    int[] arr = new int[length];
    for (int i = 0; i < arr.length; i++) {
        System.out.println("Enter the number " + (i + 1) + ": ");
        //Below is the way to collect the element from the user
        arr[i] = input.nextInt();

        // auto generate the elements
        //arr[i] = (int)(Math.random()*100);
    }
    input.close();
    System.out.println(Arrays.toString(arr));

For users looking for a Swift 3.0 version of @amro's answer:

     userDefaults.set(true, forKey: "hasRunBefore")

Under Linux, to find the location of $JAVA_HOME:

readlink -f /usr/bin/java | sed "s:bin/java::"

the cacerts are under lib/security/cacerts:

$(readlink -f /usr/bin/java | sed "s:bin/java::")lib/security/cacerts

Under mac OS X , to find $JAVA_HOME run:

/usr/libexec/java_home

the cacerts are under Home/lib/security/cacerts:

$(/usr/libexec/java_home)/lib/security/cacerts

UPDATE (OS X with JDK)

above code was tested on computer without JDK installed. With JDK installed, as pR0Ps said, it's at

$(/usr/libexec/java_home)/jre/lib/security/cacerts

What worked for me was:

1. Update prettier to version 2.2.1 (latest version at the moment) as Roberto LL suggested. To do it execute

npm update prettier

2. Execute lint fix as Hakan suggested (This will modify all files in the project to convert line ending to LF).

npm run lint -- --fix

It was not necessary to change .eslintrc and .prettierrc files!

Oracle stores only the fractions up to second in a DATE field.

Use TIMESTAMP instead:

SELECT  TO_TIMESTAMP('2004-09-30 23:53:48,140000000', 'YYYY-MM-DD HH24:MI:SS,FF9')
FROM    dual

, possibly casting it to a DATE then:

SELECT  CAST(TO_TIMESTAMP('2004-09-30 23:53:48,140000000', 'YYYY-MM-DD HH24:MI:SS,FF9') AS DATE)
FROM    dual

Use this SQL command to drop a unique constraint:

ALTER TABLE tbl_name
DROP INDEX column_name

Oracle has various combinations of b-tree, bitmap, partitioned and non-partitioned, reverse byte, bitmap join, and domain indexes.

Here's a link to the 11gR1 documentation on the subject: http://download.oracle.com/docs/cd/B28359_01/server.111/b28274/data_acc.htm#PFGRF004

This warning comes because your dataframe x is a copy of a slice. This is not easy to know why, but it has something to do with how you have come to the current state of it.

You can either create a proper dataframe out of x by doing

x = x.copy()

This will remove the warning, but it is not the proper way

You should be using the DataFrame.loc method, as the warning suggests, like this:

x.loc[:,'Mass32s'] = pandas.rolling_mean(x.Mass32, 5).shift(-2)

u can also try from yours design

    <div <%=If(True = True, "style='display: none;'", "")%> >True</div>
<div <%=If(True = False, "style='display: none;'", "")%> >False</div>
<div <%=If(Session.Item("NameExist") IsNot Nothing, "style='display: none;'", "")%> >NameExist</div>
<div <%=If(Session.Item("NameNotExist") IsNot Nothing, "style='display: none;'", "")%> >NameNotExist</div>

Output html

    <div style='display: none;' > True</div>
<div  >False</div>
<div style='display: none;' >NameExist</div>
<div  >NameNotExist</div>

I solved by this simple trick.

I had this issue. This how I fixed it.

The connection seems to close while trying to flush or persist. Trying to reopen it is a bad choice because creates new issues. I tryed to understand why the connection was closed and found that I was doing too many modifications before the persist.

persist() earlier solved the issue.

There are several good answers on here but I wanted to add one since it may be helpful for users like me who have Tomcat installed as a service on a Windows machine.

Option 3 here: http://www.codejava.net/servers/tomcat/4-ways-to-change-jre-for-tomcat

Basically, open tomcatw.exe and point Tomcat to the version of the JVM you need to use then restart the service. Ensure your deployed applications still work as well.

Your function declares a constant reference to a string:

int foo(const string &myname) {
  cout << "called foo for: " << myname << endl;
  return 0;
}

A reference has some special properties, which make it a safer alternative to pointers in many ways:

• it can never be NULL
• it must always be initialised
• it cannot be changed to refer to a different variable once set
• it can be used in exactly the same way as the variable to which it refers (which means you do not need to deference it like a pointer)

How does the function signature differ from the equivalent C:

int foo(const char *myname)

There are several differences, since the first refers directly to an object, while const char* must be dereferenced to point to the data.

Is there a difference between using string *myname vs string &myname?

The main difference when dealing with parameters is that you do not need to dereference &myname. A simpler example is:

int add_ptr(int *x, int* y)
{
    return *x + *y;
}
int add_ref(int &x, int &y)
{
    return x + y;
}

which do exactly the same thing. The only difference in this case is that you do not need to dereference x and y as they refer directly to the variables passed in.

const string &GetMethodName() { ... }

What is the & doing here? Is there some website that explains how & is used differently in C vs C++?

This returns a constant reference to a string. So the caller gets to access the returned variable directly, but only in a read-only sense. This is sometimes used to return string data members without allocating extra memory.

There are some subtleties with references - have a look at the C++ FAQ on References for some more details.

You need to open the file in binary mode i.e. wb instead of w. If you don't, the end of line characters are auto-converted to OS specific ones.

Here is an excerpt from Python reference about open().

The default is to use text mode, which may convert '\n' characters to a platform-specific representation on writing and back on reading.

var i = 10;
i = i / -1;

Result: -10

var i = -10;
i = i / -1;

Result: 10

If you divide by negative 1, it will always flip your number either way.

try changing the connection port to 8012

open xampp as administrator

Mysql config => my.ini change the port from 3306 to 8012

close and run it again I hope it will work.

If you've already displayed the element on the page previously, you can simply take the height directly from the DOM element (reachable in jQuery with .get(0)), since it is set even when the element is hidden:

$('.hidden-element').get(0).height;

same for the width:

$('.hidden-element').get(0).width;

(thanks to Skeets O'Reilly for correction)

I have MinGW and also mingw32-make.exe in my bin in the C:\MinGW\bin . same other I add bin path to my windows path. After that I change it's name to make.exe . Now I can Just write command "make" in my Makefile direction and execute my Makefile same as Linux.

For reloading the page for a given route path :-

$location.path('/path1/path2');
$route.reload();

Here's C/C++ recursive function that makes use of dirname() to traverse bottom-up the directory tree. It will stop as soon as it finds an existing ancestor.

#include <libgen.h>
#include <string.h>

int create_dir_tree_recursive(const char *path, const mode_t mode)
{
    if (strcmp(path, "/") == 0) // No need of checking if we are at root.
        return 0;

    // Check whether this dir exists or not.
    struct stat st;
    if (stat(path, &st) != 0 || !S_ISDIR(st.st_mode))
    {
        // Check and create parent dir tree first.
        char *path2 = strdup(path);
        char *parent_dir_path = dirname(path2);
        if (create_dir_tree_recursive(parent_dir_path, mode) == -1)
            return -1;

        // Create this dir.
        if (mkdir(path, mode) == -1)
            return -1;
    }

    return 0;
}

Your syntax is wrong.

You need to call attr with two parameters, like this:

$('.salesperson', newOption).attr('defaultSelected', "selected");

Your current code assigns the value "selected" to the variable defaultSelected, then passes that value to the attr function, which will then return the value of the selected attribute.

ALL YOU HAVE TO DO:

HTML:

<table id="my-table"><tr>
<td> CELL 1 With a lot of text in it</td>
<td> CELL 2 </td>
<td> CELL 3 </td>
<td> CELL 4 With a lot of text in it </td>
<td> CELL 5 </td>
</tr></table>

CSS:

#my-table{width:100%;} /*or whatever width you want*/
#my-table td{width:2000px;} /*something big*/

if you have th you need to set it too like this:

#my-table th{width:2000px;}

You aren't assigning the result of the replace method back to your variable. When you call replace, it returns a new string without modifying the old one.

For example, load this into your favorite browser:

<html><head></head><body>
    <script type="text/javascript">
        var str1 = "a,d,k";
        str1.replace(/\,/g,"");
        var str2 = str1.replace(/\,/g,"");
        alert (str1);
        alert (str2);
    </script>
</body></html>

In this case, str1 will still be "a,d,k" and str2 will be "adk".

If you want to change str1, you should be doing:

var str1 = "a,d,k";
str1 = str1.replace (/,/g, "");

Read many answers and posts and determined the most accurate solution. Tested in Safari, Chrome, Firefox (desktop and iOS versions). First we need to detect Apple vendor and then exclude Chrome and Firefox (for iOS).

let isSafari = navigator.vendor.match(/apple/i) &&
             !navigator.userAgent.match(/crios/i) &&
             !navigator.userAgent.match(/fxios/i);

if (isSafari) {
  //
} else {
  //
}

You can use mkdir:

$ man 2 mkdir

#include <sys/stat.h>
#include <sys/types.h>

int result = mkdir("/home/me/test.txt", 0777);

Try > workdirectory/filename.txt

This would:

• truncate the file if it exists
• create if it doesn't exist

You can consider it equivalent to:

rm -f workdirectory/filename.txt; touch workdirectory/filename.txt

There is a plugin to do just that for jQuery, jquery.serializeJSON. I have used it successfully on a few projects now. It works like a charm.

You should copy folder WebApplications from C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\ to C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v11.0\

What will you have? You'll probably end up with a default search and a search that you load from somewhere. Default search requires a default constructor, so make one like Dismissile has already suggested.

If you load the search criteria from elsewhere, then you should probably have some mapping logic.

You can have a look at the source code (here it is v1.7.2).

Except for the animation that we can set, this also keep in memory the old display style (which is not in all cases block, it can also be inline, table-cell, ...).

You are not selecting multiple indexes with PriceList[0][1][2][3][4][5][6] , instead each [] is going into a sub index.

Try this

PizzaChange=float(input("What would you like the new price for all standard pizzas to be? "))      
PriceList[0:7]=[PizzaChange]*7  
PriceList[7:11]=[PizzaChange+3]*4

Since Python 3.4 / PEP450 there is a statistics module in the standard library, which has a method stdev for calculating the standard deviation of iterables like yours:

>>> A_rank = [0.8, 0.4, 1.2, 3.7, 2.6, 5.8]
>>> import statistics
>>> statistics.stdev(A_rank)
2.0634114147853952

The clue is to work with the dict's items (i.e. key-value pair tuples). Then by using the second element of the item as the max key (as opposed to the dict key) you can easily extract the highest value and its associated key.

 mydict = {'A':4,'B':10,'C':0,'D':87}
>>> max(mydict.items(), key=lambda k: k[1])
('D', 87)
>>> min(mydict.items(), key=lambda k: k[1])
('C', 0)

You could try:

Hello! Here is some code:_x000D_
_x000D_
<xmp>_x000D_
<div id="hello">_x000D_
_x000D_
</div>_x000D_
</xmp>

Use

YourCommaSeparatedString.split(',');

Well, you can always try WHERE textcolumn LIKE "%SUBSTRING%" - but this is guaranteed to be pretty slow, as your query can't do an index match because you are looking for characters on the left side.

It depends on the field type - a textarea usually won't be saved as VARCHAR, but rather as (a kind of) TEXT field, so you can use the MATCH AGAINST operator.

To get the columns that don't match, simply put a NOT in front of the like: WHERE textcolumn NOT LIKE "%SUBSTRING%".

Whether the search is case-sensitive or not depends on how you stock the data, especially what COLLATION you use. By default, the search will be case-insensitive.

Updated answer to reflect question update:

I say that doing a WHERE field LIKE "%value%" is slower than WHERE field LIKE "value%" if the column field has an index, but this is still considerably faster than getting all values and having your application filter. Both scenario's:

1/ If you do SELECT field FROM table WHERE field LIKE "%value%", MySQL will scan the entire table, and only send the fields containing "value".

2/ If you do SELECT field FROM table and then have your application (in your case PHP) filter only the rows with "value" in it, MySQL will also scan the entire table, but send all the fields to PHP, which then has to do additional work. This is much slower than case #1.

Solution: Please do use the WHERE clause, and use EXPLAIN to see the performance.

Once you have connected your UITableView delegate and datasource to your controller, you could do something like this:

ObjC

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {

    NSString *sectionName;
    switch (section) {
        case 0:
            sectionName = NSLocalizedString(@"mySectionName", @"mySectionName");
            break;
        case 1:
            sectionName = NSLocalizedString(@"myOtherSectionName", @"myOtherSectionName");
            break;
        // ...
        default:
            sectionName = @"";
            break;
    }    
    return sectionName;
}

Swift

func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {

    let sectionName: String
    switch section {
        case 0:
            sectionName = NSLocalizedString("mySectionName", comment: "mySectionName")
        case 1:
            sectionName = NSLocalizedString("myOtherSectionName", comment: "myOtherSectionName")
        // ...
        default:
            sectionName = ""
    }
    return sectionName
}

db.<COLLECTION NAME>.find({ "<FIELD NAME>": { $exists: true, $ne: null } })

I did not know about DMBS_METADATA, but your answers prompted me to create a utility to script all objects owned by an Oracle user.

HTML

<a href="demoLink" id="myLink"> myLink </a>
<button onclick="fireLink(event)"> Call My Link </button>

JS

// click event listener of the link element --------------  
document.getElementById('myLink').addEventListener("click", callLink);
function callLink(e) {
    // code to fire
}

// function invoked by the button element ----------------
function fireLink(event) {                   
    document.getElementById('myLink').click();      // script calls the "click" event of the link element 
}

You have to call the super.paintComponent(); as well, to allow the Java API draw the original background. The super refers to the original JPanel code.

public void paintComponent(Graphics g){
    super.paintComponent(g);

    g.setColor(Color.red);
    g.fillOval(player.getxCenter(), player.getyCenter(), player.getRadius(), player.getRadius());
}

There is another case where 'Java Class' don't show, maybe some reserved words exist in the package name, for example:

com.liuyong.package.case

com.liuyong.import.package

It's the same reason as @kuporific 's answer: the package name is invalid.

Talking about IBM Notes v. 9 is pretty easy.

To choose the e-mail to be attached and drag until the new e-mail.

You should use the secondary constructor for File to specify the directory in which it is to be symbolically created. This is important because the answers that say to create a file by prepending the directory name to original name, are not as system independent as this method.

Sample code:

String dirName = /* something to pull specified dir from input */;

String fileName = "test.txt";
File dir = new File (dirName);
File actualFile = new File (dir, fileName);

/* rest is the same */

Hope it helps.

If you are in the U.S. Pacific time zone, then the epoch for you is 4 p.m. on December 31, 1969. You added the milliseconds since the epoch to

new DateTime(1970, 01, 01)

which, since it did not have a timezone, was interpreted as being in your timezone.

There is nothing really wrong with thinking of instants in time as milliseconds since the epoch but understand the epoch is only 1970-01-01T00:00:00Z.

You can't think of instants in times, when represented as dates, without timezones.

You may need the following two functions: pad- to pad(when doing encryption) and unpad- to unpad (when doing decryption) when the length of input is not a multiple of BLOCK_SIZE.

BS = 16
pad = lambda s: s + (BS - len(s) % BS) * chr(BS - len(s) % BS) 
unpad = lambda s : s[:-ord(s[len(s)-1:])]

So you're asking the length of key? You can use the md5sum of the key rather than use it directly.

More, according to my little experience of using PyCrypto, the IV is used to mix up the output of a encryption when input is same, so the IV is chosen as a random string, and use it as part of the encryption output, and then use it to decrypt the message.

And here's my implementation, hope it will be useful for you:

import base64
from Crypto.Cipher import AES
from Crypto import Random

class AESCipher:
    def __init__( self, key ):
        self.key = key

    def encrypt( self, raw ):
        raw = pad(raw)
        iv = Random.new().read( AES.block_size )
        cipher = AES.new( self.key, AES.MODE_CBC, iv )
        return base64.b64encode( iv + cipher.encrypt( raw ) ) 

    def decrypt( self, enc ):
        enc = base64.b64decode(enc)
        iv = enc[:16]
        cipher = AES.new(self.key, AES.MODE_CBC, iv )
        return unpad(cipher.decrypt( enc[16:] ))

The tool you want is ps. To get information about what java programs are doing:

ps -F -C java 

To get information about http:

ps -F -C httpd

If your program is ending before you get a chance to run these, open another terminal and run:

while true; do ps -F -C myCoolCode ; sleep 0.5s ; done

localStorage is something that is kept on the client side. There is no data transmitted to the server side.

You can only get the data with JavaScript and you can send it to the server side with Ajax.

I also use watch: in some situations.

I had similar problem, but in folder which I wanted to move I had files which I was not tracking.

let's say I had files

a/file1
a/untracked1
b/file2
b/untracked2

And I wanted to move only tracked files to subfolder subdir, so the goal was:

subdir/a/file1
subdir/a/untracked1
subdir/b/file2
subdir/b/untracked2

what I had done was:

• I created new folder and moved all files that I was interested in moving: mkdir tmpdir && mv a b tmpdir
• checked out old files git checkout a b
• created new dir and moved clean folders (without untracked files) to new subdir: mkdir subdir && mv a b subdir
• added all files from subdir (so Git could add only tracked previously files - it was somekind of git add --update with directory change trick): git add subdir (normally this would add even untracked files - this would require creating .gitignore file)
• git status shows now only moved files
• moved rest of files from tmpdir to subdir: mv tmpdir/* subdir
• git status looks like we executed git mv :)

you have to do:

LIKE '%' + @param + '%'

You can use this one for return type of generic list:

public string ListType<T>(T value)
{
    var valueType = value.GetType().GenericTypeArguments[0].FullName;
    return valueType;
}

With a bit of extension method abuse, we can get the following "elegant" solution:

using System;

namespace Elegant {
    public class Range {
        public int Lower { get; set; }
        public int Upper { get; set; }
    }

    public static class Ext {
        public static Range To(this int lower, int upper) {
            return new Range { Lower = lower, Upper = upper };
        }

        public static bool In(this int n, Range r) {
            return n >= r.Lower && n <= r.Upper;
        }
    }

    class Program {
        static void Main() {
            int x = 55;
            if (x.In(1.To(100)))
                Console.WriteLine("it's in range! elegantly!");
        }
    }
}

Because you set visibility either true or false. try that setVisible(0) to visible true . and setVisible(4) to visible false.

If you want you can use the recommended Bootstrap plugin to dynamize your custom file input: https://www.npmjs.com/package/bs-custom-file-input

This plugin can be use with or without jQuery and works with React an Angular

I think the Angular 2 way of doing this is the filter method:

this.data = this.data.filter(item => item !== data_item);

where data_item is the item that should be deleted

Fundamentally you hadn't declare location which is what nginx uses to bind URL with resources.

 server {
            listen       80;
            server_name  localhost;

            access_log  logs/localhost.access.log  main;

            location / {
                root /var/www/board/public;
                index index.html index.htm index.php;
            }
       }

Another syntax of doing the same thing is:

rails g migration AddUserToUpload user:belongs_to

To actually cover your pattern, i.e, valid file names according to your rules, I think that you need a little more. Note this doesn't match legal file names from a system perspective. That would be system dependent and more liberal in what it accepts. This is intended to match your acceptable patterns.

^([a-zA-Z0-9]+[_-])*[a-zA-Z0-9]+\.[a-zA-Z0-9]+$

Explanation:

• ^ Match the start of a string. This (plus the end match) forces the string to conform to the exact expression, not merely contain a substring matching the expression.
• ([a-zA-Z0-9]+[_-])* Zero or more occurrences of one or more letters or numbers followed by an underscore or dash. This causes all names that contain a dash or underscore to have letters or numbers between them.
• [a-zA-Z0-9]+ One or more letters or numbers. This covers all names that do not contain an underscore or a dash.
• \. A literal period (dot). Forces the file name to have an extension and, by exclusion from the rest of the pattern, only allow the period to be used between the name and the extension. If you want more than one extension that could be handled as well using the same technique as for the dash/underscore, just at the end.
• [a-zA-Z0-9]+ One or more letters or numbers. The extension must be at least one character long and must contain only letters and numbers. This is typical, but if you wanted allow underscores, that could be addressed as well. You could also supply a length range {2,3} instead of the one or more + matcher, if that were more appropriate.
• $ Match the end of the string. See the starting character.

Week Start & End Date From Date For Power BI Dax Formula

WeekStartDate = [DateColumn] - (WEEKDAY([DateColumn])-1)
WeekEndDate = [DateColumn] + (7-WEEKDAY([DateColumn]))

To your first question: I would go with Paul R's comment and terminate with '\0'. But the value 0 itself works also fine. A matter of taste. But don't use the MACRO NULLwhich is meant for pointers.

To your second question: If your string is not terminated with\0, it might still print the expected output because following your string is a non-printable character in your memory. This is a really nasty bug though, since it might blow up when you might not expect it. Always terminate a string with '\0'.

No, you can't.

It's a security/anti-phishing feature.

I didn't see it mentioned here, but you can also use CSS spec selectors. See the docs

$('#parentContainer td:nth-child(2)')

If this doesn't work I'm out of ideas. This way you get the 4 columns in both tables (as Bar owns them and Foo uses them to reference Bar) and the generated IDs in both entities. The set of 4 columns has to be unique in Bar so the many-to-one relation doesn't become a many-to-many.

@Embeddable
public class AnEmbeddedObject
{
    @Column(name = "column_1")
    private Long column1;
    @Column(name = "column_2")
    private Long column2;
    @Column(name = "column_3")
    private Long column3;
    @Column(name = "column_4")
    private Long column4;
}

@Entity
public class Foo
{
    @Id
    @Column(name = "id")
    @GeneratedValue(generator = "seqGen")
    @SequenceGenerator(name = "seqGen", sequenceName = "FOO_ID_SEQ", allocationSize = 1)
    private Long id;
    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumns({
        @JoinColumn(name = "column_1", referencedColumnName = "column_1"),
        @JoinColumn(name = "column_2", referencedColumnName = "column_2"),
        @JoinColumn(name = "column_3", referencedColumnName = "column_3"),
        @JoinColumn(name = "column_4", referencedColumnName = "column_4")
    })
    private Bar bar;
}

@Entity
@Table(uniqueConstraints = @UniqueConstraint(columnNames = {
    "column_1",
    "column_2",
    "column_3",
    "column_4"
}))
public class Bar
{
    @Id
    @Column(name = "id")
    @GeneratedValue(generator = "seqGen")
    @SequenceGenerator(name = "seqGen", sequenceName = "BAR_ID_SEQ", allocationSize = 1)
    private Long id;
    @Embedded
    private AnEmbeddedObject anEmbeddedObject;
}

Casting is not a mathematical operation and doesn't behave as such. Try

int y = (int)round(x);

function validateFileExtensions(){
        var validFileExtensions = ["jpg", "jpeg", "gif", "png"];
        var fileErrors = new Array();

        $( "input:file").each(function(){
            var file = $(this).value;
            var ext = file.split('.').pop();
            if( $.inArray( ext, validFileExtensions ) == -1) {
                fileErrors.push(file);
            }
        });

        if( fileErrors.length > 0 ){
            var errorContainer = $("#validation-errors");
            for(var i=0; i < fileErrors.length; i++){
                errorContainer.append('<label for="title" class="error">* File:'+ file +' do not have a valid format!</label>');
            }
            return false;
        }
        return true;
    }

Will something like this work for you? What this does is query the content resolver to find the file path data that is stored for that content entry

public static String getRealPathFromUri(Context context, Uri contentUri) {
    Cursor cursor = null;
    try {
        String[] proj = { MediaStore.Images.Media.DATA };
        cursor = context.getContentResolver().query(contentUri, proj, null, null, null);
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        return cursor.getString(column_index);
    } finally {
        if (cursor != null) {
            cursor.close();
        }
    }
}

This will end up giving you an absolute file path that you can construct a file uri from

My answer below shows how to embed images using data URIs. This is useful for the web, but will not work reliably for most email clients. For email purposes be sure to read Shadow2531's answer.

Base-64 data is legal in an img tag and I believe your question is how to properly insert such an image tag.

You can use an online tool or a few lines of code to generate the base 64 string.

The syntax to source the image from inline data is:

<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUA
AAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO

Two flavours of module.exports / require:

(see here)

Flavour 1
export file (misc.js):

var x = 5;
var addX = function(value) {
  return value + x;
};
module.exports.x = x;
module.exports.addX = addX;

other file:

var misc = require('./misc');
console.log("Adding %d to 10 gives us %d", misc.x, misc.addX(10));

Flavour 2
export file (user.js):

var User = function(name, email) {
  this.name = name;
  this.email = email;
};
module.exports = User;

other file:

var user = require('./user');
var u = new user();

Here are the steps:

1. Start the command line.
2. Enter the folder containing the .m file with cd C:\M1\M2\M3
3. Run the following: C:\E1\E2\E3\matlab.exe -r mfile

Windows systems will use your current folder as the location for MATLAB to search for .m files, and the -r option tries to start the given .m file as soon as startup occurs.

I have a helper method for this in my System.Web.UI.Page class

protected T FindControlFromMaster<T>(string name) where T : Control
{
     MasterPage master = this.Master;
     while (master != null)
     {
         T control = master.FindControl(name) as T;
         if (control != null)
             return control;

         master = master.Master;
     }
     return null;
}

then you can access using below code.

Label lblStatus = FindControlFromMaster<Label>("lblStatus");
if(lblStatus!=null) 
    lblStatus.Text = "something";

BIT should only allow 0 and 1 (and NULL, if the field is not defined as NOT NULL). TINYINT(1) allows any value that can be stored in a single byte, -128..127 or 0..255 depending on whether or not it's unsigned (the 1 shows that you intend to only use a single digit, but it does not prevent you from storing a larger value).

For versions older than 5.0.3, BIT is interpreted as TINYINT(1), so there's no difference there.

BIT has a "this is a boolean" semantic, and some apps will consider TINYINT(1) the same way (due to the way MySQL used to treat it), so apps may format the column as a check box if they check the type and decide upon a format based on that.

First of all, understand what's wrong with this code:

var funcs = [];
for (var i = 0; i < 3; i++) {          // let's create 3 functions
    funcs[i] = function() {            // and store them in funcs
        console.log("My value: " + i); // each should log its value.
    };
}
for (var j = 0; j < 3; j++) {
    funcs[j]();                        // and now let's run each one to see
}

Here when the funcs[] array is being initialized, i is being incremented, the funcs array is initialized and the size of func array becomes 3, so i = 3,. Now when the funcs[j]() is called, it is again using the variable i, which has already been incremented to 3.

Now to solve this, we have many options. Below are two of them:

1. We can initialize i with let or initialize a new variable index with let and make it equal to i. So when the call is being made, index will be used and its scope will end after initialization. And for calling, index will be initialized again:

   var funcs = [];
   for (var i = 0; i < 3; i++) {          
       let index = i;
       funcs[i] = function() {            
           console.log("My value: " + index); 
       };
   }
   for (var j = 0; j < 3; j++) {
       funcs[j]();                        
   }
   

2. Other Option can be to introduce a tempFunc which returns the actual function:

   var funcs = [];
   function tempFunc(i){
       return function(){
           console.log("My value: " + i);
       };
   }
   for (var i = 0; i < 3; i++) {  
       funcs[i] = tempFunc(i);                                     
   }
   for (var j = 0; j < 3; j++) {
       funcs[j]();                        
   }

The solutions above do not work on Linux.

Using .NET Core, attempting to execute new Uri("/home/foo/README.md") results in an exception:

Unhandled Exception: System.UriFormatException: Invalid URI: The format of the URI could not be determined.
   at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind)
   at System.Uri..ctor(String uriString)
   ...

You need to give the CLR some hints about what sort of URL you have.

This works:

Uri fileUri = new Uri(new Uri("file://"), "home/foo/README.md");

...and the string returned by fileUri.ToString() is "file:///home/foo/README.md"

This works on Windows, too.

new Uri(new Uri("file://"), @"C:\Users\foo\README.md").ToString()

...emits "file:///C:/Users/foo/README.md"

myList.GroupBy(i => i.id).Select(group => group.First())

This is my main activity where i take the username and password from edit text and setting to the intent

class MainActivity : AppCompatActivity() {
val userName = null
val password = null
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
button.setOnClickListener {
    val intent = Intent(this@MainActivity,SecondActivity::class.java);
    var userName = username.text.toString()
    var password = password_field.text.toString()
    intent.putExtra("Username", userName)
    intent.putExtra("Password", password)
    startActivity(intent);
 }
}

This is my second activity where i have to receive values from the main activity

override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_second)
var strUser: String = intent.getStringExtra("Username")
var strPassword: String = intent.getStringExtra("Password")
user_name.setText("Seelan")
passwor_print.setText("Seelan")
}

Are you looking for something like this?

SELECT CASE WHEN LEFT(created_ts, 1) LIKE '[0-9]' 
            THEN CONVERT(VARCHAR(10), CONVERT(datetime, created_ts,   1), 101)
            ELSE CONVERT(VARCHAR(10), CONVERT(datetime, created_ts, 109), 101)
      END created_ts
  FROM table1

Output:

| CREATED_TS |
|------------|
| 02/20/2012 |
| 11/29/2012 |
| 02/20/2012 |

Here is SQLFiddle demo

Starting from Visual Studio 2017 another solution to keep using the AssemblyInfo.cs file is to turn off automatic assembly info generation like this:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <GenerateAssemblyInfo>false</GenerateAssemblyInfo>
  </PropertyGroup>
</Project>

I personally find it very useful for projects which need to support both .NET Framework and .NET Standard.

file_name = open("data.json", "w")
json.dump(test_response, file_name)
file_name.close()

or use context manager, which is better:

with open("data.json", "w") as file_name:
    json.dump(test_response, file_name)

I just ran into this problem and stumbled across a different situation. Although it's probably just a unicorn, I thought I'd lay it out.

I had one session that was smaller, and I noticed that the font sizes were different: the smaller session had the smaller fonts. Apparently, I had changed window font sizes for some reason.

So in OS X, I just did Cmd-+ on the smaller sized session, and it snapped back into place.

You could also use indexOf instead to do this

var i = review.indexOf('\u2022 \u2022 \u2022');
if (i !== -1) review.splice(i,1);

I have created a data frame in a for loop with the help of a temporary empty data frame. Because for every iteration of for loop, a new data frame will be created thereby overwriting the contents of previous iteration.

Hence I need to move the contents of the data frame to the empty data frame that was created already. It's as simple as that. We just need to use .append function as shown below :

temp_df = pd.DataFrame() #Temporary empty dataframe
for sent in Sentences:
    New_df = pd.DataFrame({'words': sent.words}) #Creates a new dataframe and contains tokenized words of input sentences
    temp_df = temp_df.append(New_df, ignore_index=True) #Moving the contents of newly created dataframe to the temporary dataframe

Outside the for loop, you can copy the contents of the temporary data frame into the master data frame and then delete the temporary data frame if you don't need it

If you are using Query builder then you may use a blow

DB::table(Newsletter Subscription)
->select('*')
->whereIn('id', $send_users_list)
->get()

If you are working with Eloquent then you can use as below

$sendUsersList = Newsletter Subscription:: select ('*')
                ->whereIn('id', $send_users_list)
                ->get();

Install Multiple Versions Of Xcode using the Xcode-Install Ruby Gem

You can do this whole process a lot easier if you use the xcode-install RubyGem.

If you already have a working installation of the Xcode CommandLineTools and Ruby (I'd suggest using Homebrew for installing Ruby) but I think it works with the Ruby supplied by macOS as well if you install the Gem either using sudo or as a user install. (Details on the GitHub page) Basically:

    $ gem install xcode-install
    $ xcversion list
    6.0.1
    6.1
    6.1.1
    6.2 (installed)
    6.3
    $ xcversion install 8
    ######################################################################## 100.0%
    Please authenticate for Xcode installation...

    Xcode 8
    Build version 6D570

To select a version as active, you'll run:
$ xcversion select 8

To select a version as active and change the symlink at /Applications/Xcode, you'll run:
$ xcversion select 8 --symlink

xcode-install can also manage your local simulators using the simulators command.

Read the instructions on the GitHub Project page for more info.

Another alternative with data.table.

EXAMPLE DATA

dt1 <- data.table(df1)
dt2 <- data.table(df2)
setkey(dt1,x)
setkey(dt2,x)

CODE

dt2[dt1,list(y=ifelse(is.na(y),0,y))]

Here's mine

public static String dec2Hex(int num)
{
    String hex = "";

    while (num != 0)
    {
        if (num % 16 < 10)
            hex = Integer.toString(num % 16) + hex;
        else
            hex = (char)((num % 16)+55) + hex;
        num = num / 16;
    }

    return hex;
}

Introduction

Object-Relational Mapping (ORM) is a technique that lets you query and manipulate data from a database using an object-oriented paradigm. When talking about ORM, most people are referring to a library that implements the Object-Relational Mapping technique, hence the phrase "an ORM".

An ORM library is a completely ordinary library written in your language of choice that encapsulates the code needed to manipulate the data, so you don't use SQL anymore; you interact directly with an object in the same language you're using.

For example, here is a completely imaginary case with a pseudo language:

You have a book class, you want to retrieve all the books of which the author is "Linus". Manually, you would do something like that:

book_list = new List();
sql = "SELECT book FROM library WHERE author = 'Linus'";
data = query(sql); // I over simplify ...
while (row = data.next())
{
     book = new Book();
     book.setAuthor(row.get('author');
     book_list.add(book);
}

With an ORM library, it would look like this:

book_list = BookTable.query(author="Linus");

The mechanical part is taken care of automatically via the ORM library.

Pros and Cons

Using ORM saves a lot of time because:

• DRY: You write your data model in only one place, and it's easier to update, maintain, and reuse the code.
• A lot of stuff is done automatically, from database handling to I18N.
• It forces you to write MVC code, which, in the end, makes your code a little cleaner.
• You don't have to write poorly-formed SQL (most Web programmers really suck at it, because SQL is treated like a "sub" language, when in reality it's a very powerful and complex one).
• Sanitizing; using prepared statements or transactions are as easy as calling a method.

Using an ORM library is more flexible because:

• It fits in your natural way of coding (it's your language!).
• It abstracts the DB system, so you can change it whenever you want.
• The model is weakly bound to the rest of the application, so you can change it or use it anywhere else.
• It lets you use OOP goodness like data inheritance without a headache.

But ORM can be a pain:

• You have to learn it, and ORM libraries are not lightweight tools;
• You have to set it up. Same problem.
• Performance is OK for usual queries, but a SQL master will always do better with his own SQL for big projects.
• It abstracts the DB. While it's OK if you know what's happening behind the scene, it's a trap for new programmers that can write very greedy statements, like a heavy hit in a for loop.

How to learn about ORM?

Well, use one. Whichever ORM library you choose, they all use the same principles. There are a lot of ORM libraries around here:

• Java: Hibernate.
• PHP: Propel or Doctrine (I prefer the last one).
• Python: the Django ORM or SQLAlchemy (My favorite ORM library ever).
• C#: NHibernate or Entity Framework

If you want to try an ORM library in Web programming, you'd be better off using an entire framework stack like:

• Symfony (PHP, using Propel or Doctrine).
• Django (Python, using a internal ORM).

Do not try to write your own ORM, unless you are trying to learn something. This is a gigantic piece of work, and the old ones took a lot of time and work before they became reliable.

here is my solution:

public static Bitmap getBitmapFromView(View view) {
    Bitmap returnedBitmap = Bitmap.createBitmap(view.getWidth(), view.getHeight(),Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(returnedBitmap);
    Drawable bgDrawable =view.getBackground();
    if (bgDrawable!=null) 
        bgDrawable.draw(canvas);
    else 
        canvas.drawColor(Color.WHITE);
    view.draw(canvas);
    return returnedBitmap;
}

Enjoy :)

Here's one reason you shouldn't use it: it's going to piss off most anti-virus programs running on Windows if you're passing the program over to another machine because it's a security threat. Even if your program only consists of a simple cout << "hello world\n"; system("pause"); It's resource heavy and the program gets access to the cmd command, which anti viruses see as a threat.

From my experience I would advise great caution with using DoEvents in .NET. I experienced some very strange results when using DoEvents in a TabControl containing DataGridViews. On the other hand, if all you're dealing with is a small form with a progress bar then it might be OK.

The bottom line is: if you are going to use DoEvents, then you need to test it thoroughly before deploying your application.

When setting your display to flex, you could simply use the flex property to mark which content can grow and which content cannot.

Flex property

div.content {_x000D_
 height: 300px;_x000D_
 display: flex;_x000D_
 flex-direction: column;_x000D_
}_x000D_
_x000D_
div.up {_x000D_
  flex: 1;_x000D_
}_x000D_
_x000D_
div.down {_x000D_
  flex: none;_x000D_
}

<div class="content">_x000D_
  <div class="up">_x000D_
    <h1>heading 1</h1>_x000D_
    <h2>heading 2</h2>_x000D_
    <p>Some more or less text</p>_x000D_
  </div>_x000D_
_x000D_
  <div class="down">_x000D_
    <a href="/" class="button">Click me</a>_x000D_
  </div>_x000D_
</div>

"Confirm" in Javascript stops the whole process until it gets a mouse response on its buttons. If that is what you are looking for, you can refer jquery-ui but if you have nothing running behind your process while receiving the response and you control the flow programatically, take a look at this. You will have to hard-code everything by yourself but you have complete command over customization. https://www.w3schools.com/howto/howto_css_modals.asp

if (Enum.IsDefined(typeof(foo), value))
{
   return (Foo)Enum.Parse(typeof(foo), value);
}

Hope this helps

Edit This answer got down voted as value in my example is a string, where as the question asked for an int. My applogies; the following should be a bit clearer :-)

Type fooType = typeof(foo);

if (Enum.IsDefined(fooType , value.ToString()))
{
   return (Foo)Enum.Parse(fooType , value.ToString());
}

From what I learned after several days of research, Here is the Guide for ASP .Net Core MVC 2.x Custom User Authentication

In Startup.cs :

Add below lines to ConfigureServices method :

public void ConfigureServices(IServiceCollection services)
{

services.AddAuthentication(
    CookieAuthenticationDefaults.AuthenticationScheme
).AddCookie(CookieAuthenticationDefaults.AuthenticationScheme,
    options =>
    {
        options.LoginPath = "/Account/Login";
        options.LogoutPath = "/Account/Logout";
    });

    services.AddMvc();

    // authentication 
    services.AddAuthentication(options =>
    {
       options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
    });

    services.AddTransient(
        m => new UserManager(
            Configuration
                .GetValue<string>(
                    DEFAULT_CONNECTIONSTRING //this is a string constant
                )
            )
        );
     services.AddDistributedMemoryCache();
}

keep in mind that in above code we said that if any unauthenticated user requests an action which is annotated with [Authorize] , they well force redirect to /Account/Login url.

Add below lines to Configure method :

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
        app.UseBrowserLink();
        app.UseDatabaseErrorPage();
    }
    else
    {
        app.UseExceptionHandler(ERROR_URL);
    }
     app.UseStaticFiles();
     app.UseAuthentication();
     app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: DEFAULT_ROUTING);
    });
}

Create your UserManager class that will also manage login and logout. it should look like below snippet (note that i'm using dapper):

public class UserManager
{
    string _connectionString;

    public UserManager(string connectionString)
    {
        _connectionString = connectionString;
    }

    public async void SignIn(HttpContext httpContext, UserDbModel user, bool isPersistent = false)
    {
        using (var con = new SqlConnection(_connectionString))
        {
            var queryString = "sp_user_login";
            var dbUserData = con.Query<UserDbModel>(
                queryString,
                new
                {
                    UserEmail = user.UserEmail,
                    UserPassword = user.UserPassword,
                    UserCellphone = user.UserCellphone
                },
                commandType: CommandType.StoredProcedure
            ).FirstOrDefault();

            ClaimsIdentity identity = new ClaimsIdentity(this.GetUserClaims(dbUserData), CookieAuthenticationDefaults.AuthenticationScheme);
            ClaimsPrincipal principal = new ClaimsPrincipal(identity);

            await httpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, principal);
        }
    }

    public async void SignOut(HttpContext httpContext)
    {
        await httpContext.SignOutAsync();
    }

    private IEnumerable<Claim> GetUserClaims(UserDbModel user)
    {
        List<Claim> claims = new List<Claim>();

        claims.Add(new Claim(ClaimTypes.NameIdentifier, user.Id().ToString()));
        claims.Add(new Claim(ClaimTypes.Name, user.UserFirstName));
        claims.Add(new Claim(ClaimTypes.Email, user.UserEmail));
        claims.AddRange(this.GetUserRoleClaims(user));
        return claims;
    }

    private IEnumerable<Claim> GetUserRoleClaims(UserDbModel user)
    {
        List<Claim> claims = new List<Claim>();

        claims.Add(new Claim(ClaimTypes.NameIdentifier, user.Id().ToString()));
        claims.Add(new Claim(ClaimTypes.Role, user.UserPermissionType.ToString()));
        return claims;
    }
}

Then maybe you have an AccountController which has a Login Action that should look like below :

public class AccountController : Controller
{
    UserManager _userManager;

    public AccountController(UserManager userManager)
    {
        _userManager = userManager;
    }

    [HttpPost]
    public IActionResult LogIn(LogInViewModel form)
    {
        if (!ModelState.IsValid)
            return View(form);
         try
        {
            //authenticate
            var user = new UserDbModel()
            {
                UserEmail = form.Email,
                UserCellphone = form.Cellphone,
                UserPassword = form.Password
            };
            _userManager.SignIn(this.HttpContext, user);
             return RedirectToAction("Search", "Home", null);
         }
         catch (Exception ex)
         {
            ModelState.AddModelError("summary", ex.Message);
            return View(form);
         }
    }
}

Now you are able to use [Authorize] annotation on any Action or Controller.

Feel free to comment any questions or bug's.

I might misunderstand, but are you trying to delete files newly ignored or do you want to ignore new modifications to these files ? In this case, the thing is working.

If you want to delete ignored files previously commited, then use

git rm –cached `git ls-files -i –exclude-standard`
git commit -m 'clean up'

Let's say you have an associative array like this:

$a = array(
    "one" => 1,
    "two" => 2,
    "three" => 3,
    "seventeen" => array('x'=>123)
);

In the first iteration : $key="one" and $value=1.

Sometimes you need this key ,if you want only the value , you can avoid using it.

In the last iteration : $key='seventeen' and $value = array('x'=>123) so to get value of the first element in this array value, you need a key, x in this case: $value['x'] =123.

CookieManager.getInstance().setAcceptCookie(true); Normally it should work if your webview is already initialized

or try this:

CookieSyncManager.createInstance(this);
CookieManager cookieManager = CookieManager.getInstance();
cookieManager.removeAllCookie();
cookieManager.setAcceptCookie(true);

Better to use change event on input field.

Updated source:

var myfile="";

$('#resume_link').click(function( e ) {
    e.preventDefault();
    $('#resume').trigger('click');
});

$('#resume').on( 'change', function() {
   myfile= $( this ).val();
   var ext = myfile.split('.').pop();
   if(ext=="pdf" || ext=="docx" || ext=="doc"){
       alert(ext);
   } else{
       alert(ext);
   }
});

Updated jsFiddle.

I had a similar problem and found that if you remove the size definition, it works for some reason.

Remove:

<size
    android:width="60dp"
    android:height="40dp" />

from the shape.

Let me know if this works!

A slight generalization to Alexander's answer - np.reshape can take -1 as an argument, meaning "total array size divided by product of all other listed dimensions":

e.g. to flatten all but the last dimension:

>>> arr = numpy.zeros((50,100,25))
>>> new_arr = arr.reshape(-1, arr.shape[-1])
>>> new_arr.shape
# (5000, 25)

In my case I needed to raise an exception so I did:

class UnableToStripEnd(Exception):
    """A Exception type to indicate that the suffix cannot be removed from the text."""

    @staticmethod
    def get_exception(text, suffix):
        return UnableToStripEnd("Could not find suffix ({0}) on text: {1}."
                                .format(suffix, text))


def strip_end(text, suffix):
    """Removes the end of a string. Otherwise fails."""
    if not text.endswith(suffix):
        raise UnableToStripEnd.get_exception(text, suffix)
    return text[:len(text)-len(suffix)]

On a slightly-related topic, I wanted to do the same multi-command sudo via SSH but none of the above worked.

For example on Ubuntu,

$ ssh host.name sudo sh -c "whoami; whoami"
[sudo] password for ubuntu:
root
ubuntu

The trick discovered here is to double-quote the command.

$ ssh host.name sudo sh -c '"whoami; whoami"'
[sudo] password for ubuntu:
root
root

Other options that also work:

ssh host.name sudo sh -c "\"whoami; whoami\""
ssh host.name 'sudo sh -c "whoami; whoami"'

In principle, double-quotes are needed because I think the client shell where SSH is run strips the outermost set of quotes. Mix and match the quotes to your needs (eg. variables need to be passed in). However YMMV with the quotes especially if the remote commands are complex. In that case, a tool like Ansible will make a better choice.

I tried all the solutions and nothing worked. The following, however, does:

tr -cd '\11\12\15\40-\176'

Which I found here:

https://alvinalexander.com/blog/post/linux-unix/how-remove-non-printable-ascii-characters-file-unix

My problem needed it in a series of piped programs, not directly from a file, so modify as needed.

From what I've found online, this is a bug introduced in JDK 1.7.0_45. It appears to also be present in JDK 1.7.0_60. A bug report on Oracle's website states that, while there was a fix, it was removed before the JDK was released. I do not know why the fix was removed, but it confirms what we've already suspected -- the JDK is still broken.

The bug report claims that the error is benign and should not cause any run-time problems, though one of the comments disagrees with that. In my own experience, I have been able to work without any problems using JDK 1.7.0_60 despite seeing the message.

If this issue is causing serious problems, here are a few things I would suggest:

• Revert back to JDK 1.7.0_25 until a fix is added to the JDK.

• Keep an eye on the bug report so that you are aware of any work being done on this issue. Maybe even add your own comment so Oracle is aware of the severity of the issue.

• Try the JDK early releases as they come out. One of them might fix your problem.

Instructions for installing the JDK on Mac OS X are available at JDK 7 Installation for Mac OS X. It also contains instructions for removing the JDK.

This is what you really want.

<Button

       android:background="@color/colorAccent"
       android:drawableStart="@drawable/ic_settings_black_24dp"
       android:paddingStart="40dp"

I loved @james answer but I was looking for its inverse i.e. stop fixed position right before footer, here is what I came up with

var $fixed_element = $(".some_element")
if($fixed_element.length){
        var $offset = $(".footer").position().top,
            $wh = $(window).innerHeight(),
            $diff = $offset - $wh,
            $scrolled = $(window).scrollTop();
        $fixed_element.css("bottom", Math.max(0, $scrolled-$diff));
    }

So now the fixed element would stop right before footer. and will not overlap with it.

I was also having same issue and stuck for some days, but after some research i figured out that we can actually use chrome's "--remote-debugging-port" to intercept requests in conjunction with selenium web driver. Use following Pseudocode as a reference:-

create instance of chrome driver with remote debugging

int freePort = findFreePort();

chromeOptions.addArguments("--remote-debugging-port=" + freePort);

ChromeDriver driver = new ChromeDriver(chromeOptions);`

make a get call to http://127.0.0.1:freePort

String response = makeGetCall( "http://127.0.0.1" + freePort  + "/json" );

Extract chrome's webSocket Url to listen, you can see response and figure out how to extract

String webSocketUrl = response.substring(response.indexOf("ws://127.0.0.1"), response.length() - 4);

Connect to this socket, u can use asyncHttp

socket = maketSocketConnection( webSocketUrl );

Enable network capture

socket.send( { "id" : 1, "method" : "Network.enable" } );

Now chrome will send all network related events and captures them as follows

socket.onMessageReceived( String message ){

    Json responseJson = toJson(message);
    if( responseJson.method == "Network.responseReceived" ){
       //extract status code
    }

you can do everything mentioned in dev tools site. see https://chromedevtools.github.io/devtools-protocol/ Note:- use chromedriver 2.39 or above.

I hope it helps someone.

If there is no possibility to remove or change path to a hard disc file using Virtual Media Manager (in my case) then:

1. Open '.vbox' and '.vbox-prev' (if exist) files in any text editor.
2. Edit 'location' attribute of the element 'HardDisk' to your path, for example: "d:/VM/VirtualBox/Win10/Win10.vmdk" (screenshot).

The headers and footers for printing from browsers is, sadly, a browser preference, not a document-level element that you can style. Refer to my very similar question for further workarounds and disappointment.

For UI-Router(>=1.0), StateChange events have been deprecated. For complete migration guide, click here

To get the previous state of the current state in UI-Router 1.0+:

app.run(function ($transitions) {
    $transitions.onSuccess({}, function (trans) {
         // previous state and paramaters
         var previousState = trans.from().name;
         var previousStateParameters = trans.params('from');
    });
});

I have managed to modify some of @alpiii's code and discovered that List comprehension is a little faster than for loop. It might be caused by int(), it is not fair between list comprehension and for loop.

from functools import reduce
import datetime

def time_it(func, numbers, *args):
    start_t = datetime.datetime.now()
    for i in range(numbers):
        func(args[0])
    print (datetime.datetime.now()-start_t)

def square_sum1(numbers):
    return reduce(lambda sum, next: sum+next*next, numbers, 0)

def square_sum2(numbers):
    a = []
    for i in numbers:
        a.append(i*2)
    a = sum(a)
    return a

def square_sum3(numbers):
    sqrt = lambda x: x*x
    return sum(map(sqrt, numbers))

def square_sum4(numbers):
    return(sum([i*i for i in numbers]))

time_it(square_sum1, 100000, [1, 2, 5, 3, 1, 2, 5, 3])
time_it(square_sum2, 100000, [1, 2, 5, 3, 1, 2, 5, 3])
time_it(square_sum3, 100000, [1, 2, 5, 3, 1, 2, 5, 3])
time_it(square_sum4, 100000, [1, 2, 5, 3, 1, 2, 5, 3])

This error is caused by a line of code in /usr/share/phpmyadmin/libraries/sql.lib.php.

It seems when I installed phpMyAdmin using apt, the version in the repository (phpMyAdmin v4.6.6) is not fully compatible with PHP 7.2. There is a newer version available on the official website (v4.8 as of writing), which fixes these compatibility issues with PHP 7.2.

You can download the latest version and install it manually or wait for the repositories to update with the newer version.

Alternatively, you can make a small change to sql.lib.php to fix the error.

Firstly, backup sql.lib.php before editing.

1-interminal:

sudo cp /usr/share/phpmyadmin/libraries/sql.lib.php /usr/share/phpmyadmin/libraries/sql.lib.php.bak

2-Edit sql.lib.php. Using vi:

sudo vi /usr/share/phpmyadmin/libraries/sql.lib.php

OR Using nano:

sudo nano /usr/share/phpmyadmin/libraries/sql.lib.php

Press CTRL + W (for nano) or ? (for vi/vim) and search for (count($analyzed_sql_results['select_expr'] == 1)

Replace it with ((count($analyzed_sql_results['select_expr']) == 1)

Save file and exit. (Press CTRL + X, press Y and then press ENTER for nano users / (for vi/vim) hit ESC then type :wq and press ENTER)

Yes, you need to write it like your second line. Java doesn't have the python style syntactic sugar of your first line.

Alternatively you could put your valid values into an array and check for the existence of symbol in the array.

try this one

    <asp:DropDownList ID="ddList" runat="server">
    <asp:ListItem Value="">--Select Month--</asp:ListItem>
    <asp:ListItem Value="1">January</asp:ListItem>
    <asp:ListItem Value="2">Feburary</asp:ListItem>
    ...
    <asp:ListItem Value="12">December</asp:ListItem>
    </asp:DropDownList>

Value should be empty for the default selected listitem, then it works fine

What if using promises which ajax and checking if the file is valid and well saved in your backend, so you can use some animation in front while user is navigating thought your page.

You can even make it paralel upload or stacking with recursive approach

If you are trying to use mysqlclient on WINDOWS with this failure, try to install the lower version instead:

pip install mysqlclient==1.3.4

\d means a digit in most languages. You can also use [0-9] in all languages. For the "period or comma" use [\.,]. Depending on your language you may need more backslashes based on how you quote the expression. Ultimately, the regular expression engine needs to see a single backslash.

* means "zero-or-more", so \d* and [0-9]* mean "zero or more numbers". ? means "zero-or-one". Neither of those qualifiers means exactly one. Most languages also let you use {m,n} to mean "between m and n" (ie: {1,2} means "between 1 and 2")

Since the dot or comma and additional numbers are optional, you can put them in a group and use the ? quantifier to mean "zero-or-one" of that group.

Putting that all together you can use:

\d{1,2}([\.,][\d{1,2}])?

Meaning, one or two digits \d{1,2}, followed by zero-or-one of a group (...)? consisting of a dot or comma followed by one or two digits [\.,]\d{1,2}

I looked at a lot of these solutions and didn't like many of them. Mostly because the annoying step of having to identify your known hosts. That and JSCH is at a ridiculously low level relative to the scp command.

I found a library that doesn't require this but it's bundled up and used as a command line tool. https://code.google.com/p/scp-java-client/

I looked through the source code and discovered how to use it without the command line. Here's an example of uploading:

    uk.co.marcoratto.scp.SCP scp = new uk.co.marcoratto.scp.SCP(new uk.co.marcoratto.scp.listeners.SCPListenerPrintStream());
    scp.setUsername("root");
    scp.setPassword("blah");
    scp.setTrust(true);
    scp.setFromUri(file.getAbsolutePath());
    scp.setToUri("root@host:/path/on/remote");
    scp.execute();

The biggest downside is that it's not in a maven repo (that I could find). But, the ease of use is worth it to me.

It is possible to list all event listeners in JavaScript: It's not that hard; you just have to hack the prototype's method of the HTML elements (before adding the listeners).

function reportIn(e){
    var a = this.lastListenerInfo[this.lastListenerInfo.length-1];
    console.log(a)
}


HTMLAnchorElement.prototype.realAddEventListener = HTMLAnchorElement.prototype.addEventListener;

HTMLAnchorElement.prototype.addEventListener = function(a,b,c){
    this.realAddEventListener(a,reportIn,c); 
    this.realAddEventListener(a,b,c); 
    if(!this.lastListenerInfo){  this.lastListenerInfo = new Array()};
    this.lastListenerInfo.push({a : a, b : b , c : c});
};

Now every anchor element (a) will have a lastListenerInfo property wich contains all of its listeners. And it even works for removing listeners with anonymous functions.

Found the solution to the problem.

When you click on a thickbox link that open a iframe, it insert an iframe with an id of TB_iframeContent.

Instead of relying on the $(document).ready event in the iframe code, I just have to bind to the load event of the iframe in the parent document:

$('#TB_iframeContent', top.document).load(ApplyGalleria);

This code is in the iframe but binds to an event of a control in the parent document. It works in FireFox and IE.

actually , this has turned out to be couple of javascript changes in the code. calling of javascript method with ; at the end. placing script tags in body instead of head. and interestingly even change the text displayed (please "click") to something that is not an event. so Please rate etc.

turned debugger on safari, it didnot give much information or even errors at times.

Install GIT. During installation of GIT, add GIT Bash to windows context menu by selecting its option. After installation right click in your folder select GIT Bash Here (see attached pic) and use your sh command like for example:

sh test.sh

With async / await and Typescript I would do:

import * as fs from 'fs'

async function upsertFile(name: string) {
  try {
    // try to read file
    await fs.promises.readFile(name)
  } catch (error) {
    // create empty file, because it wasn't found
    await fs.promises.writeFile(name, '')
  }
}

EG : COMPARE TO VILLAGE NAME

ALTER PROCEDURE POSMAST
(@COLUMN_NAME VARCHAR(50))
AS
SELECT * FROM TABLE_NAME
WHERE 
village_name LIKE + @VILLAGE_NAME + '%';

Bootstrap v4+ solution

Here's a solution that doesn't require rethinking the HTML structure or any additional CSS trickery involving padding:

<html style="height:100%;">
  ...
  <body class="d-flex flex-column h-100">
    ...
    <main class="flex-grow-1">...</main>
    <footer>...</footer>
  </body>
  ...
</html>

Note that this solution allows for footers with flexible heights, which particularly comes in handy when designing pages for multiple screen sizes with content wrapping when shrunk.

Why this works

• style="height:100%;" makes the <html> tag take the whole space of the document.
• class d-flex sets display:flex to our <body> tag.
• class flex-column sets flex-direction:column to our <body> tag. Its children (<header>, <main>, <footer> and any other direct child) are now aligned vertically.
• class h-100 sets height:100% to our <body> tag, meaning it will cover the entire screen vertically.
• class flex-grow-1 sets flex-grow:1 to our <main>, effectively instructing it to fill any remaining vertical space, thus amounting to the 100% vertical height we set before on our <body> tag.

Okay here some more complex sample for the use of For /F

:: Main
@prompt -$G
    call :REGQUERY  "Software\Classes\CLSID\{3E6AE265-3382-A429-56D1-BB2B4D1D}"

@goto :EOF

:REGQUERY
:: Checks HKEY_LOCAL_MACHINE\ and HKEY_CURRENT_USER\ 
:: for the key and lists its content

    @call :EXEC "REG QUERY  HKCU\%~1"
    @call :EXEC "REG QUERY "HKLM\%~1""

@goto :EOF    

:EXEC
    @set output=

    @for /F "delims=" %%i in ('%~1 2^>nul') do @(
        set output=%%i
    )

    @if not "%output%"=="" (
        echo %1 -^> %output%
    )

@goto :EOF

I packed it into the sub function :EXEC so all of its nasty details of implementation doesn't litters the main script. So it got some kinda some batch tutorial. Notes 'bout the code:

1. the output from the command executed via call :EXEC command is stored in %output%. Batch cmd doesn't cares about scopes so %output% will be also available in the main script.
2. the @ the beginning is just decoration and there to suppress echoing the command line. You may delete them all and just put some @echo off at the first line is really dislike that. However like this I find debugging much more nice. Decoration Number two is prompt -$G. It's there to make command prompt look like this ->
3. I use :: instead of rem
4. the tilde(~) in %~1 is to remove quotes from the first argument
5. 2^>nul is there to suppress/discard stderr error output. Normally you would do it via 2>nul. Well the ^ the batch escape char is there avoids to early resolving the redirector(>). There's some simulare use a little later in the script: echo %1 -^>... so there ^ makes it possible the output a '>' via echo what else wouldn't have been possible.
6. even if the compare at @if not "%output%"==""looks like in most common programming languages - it's maybe different that you expected (if you're not used to MS-batch). Well remove the '@' at the beginning. Study the output. Change it tonot %output%==""-rerun and consider why this doesn't work. ;)

It's easy to define one yourself. That's the power of JavaScript.

if(!Array.prototype.last) {
    Array.prototype.last = function() {
        return this[this.length - 1];
    }
}

var arr = [1, 2, 5];
arr.last(); // 5

However, this may cause problems with 3rd-party code which (incorrectly) uses for..in loops to iterate over arrays.

However, if you are not bound with browser support problems, then using the new ES5 syntax to define properties can solve that issue, by making the function non-enumerable, like so:

Object.defineProperty(Array.prototype, 'last', {
    enumerable: false,
    configurable: true,
    get: function() {
        return this[this.length - 1];
    },
    set: undefined
});

var arr = [1, 2, 5];
arr.last; // 5

If RecyclerView showing only one row inside ScrollView. You just need to set height of your row to android:layout_height="wrap_content".

For others who land here in the future (including myself), add a -name option to find specific file types, for instance: find /var -name "*.php" -mtime -1 -ls

@echo off
setlocal
set "list=a b c d"
(
 for %%i in (%list%) do (
  echo(%%i
  echo(
 )
)>file.txt

You don't need - actually, can't "declare" variables in batch. Assigning a value to a variable creates it, and assigning an empty string deletes it. Any variable name that doesn't have an assigned value HAS a value of an empty string. ALL variables are strings - WITHOUT exception. There ARE operations that appear to perform (integer) mathematical functions, but they operate by converting back and forth from strings.

Batch is sensitive to spaces in variable names, so your assignment as posted would assign the string "A B C D" - including the quotes, to the variable "list " - NOT including the quotes, but including the space. The syntax set "var=string" is used to assign the value string to var whereas set var=string will do the same thing. Almost. In the first case, any stray trailing spaces after the closing quote are EXCLUDED from the value assigned, in the second, they are INCLUDED. Spaces are a little hard to see when printed.

ECHO echoes strings. Clasically, it is followed by a space - one of the default separators used by batch (the others are TAB, COMMA, SEMICOLON - any of these do just as well BUT TABS often get transformed to a space-squence by text-editors and the others have grown quirks of their own over the years.) Other characters following the O in ECHO have been found to do precisely what the documented SPACE should do. DOT is common. Open-parenthesis ( is probably the most useful since the command

ECHO.%emptyvalue%

will produce a report of the ECHO state (ECHO is on/off) whereas

ECHO(%emptyvalue%

will produce an empty line.

The problem with ECHO( is that the result "looks" unbalanced.

on Ubuntu 12.04 and the packaged version of NodeJs is too old to install Bower using the PPA

sudo add-apt-repository ppa:chris-lea/node.js 
sudo apt-get update
sudo apt-get -y install nodejs

When this has installed, check the version:

npm --version
1.4.3

Now install Bower:

sudo npm install -g bower

This will fetch and install Bower globally.

Using a supposed name property as the map key:

for (Product p: productList) { s.put(p.getName(), p); }

The answer of @PeterOlson may be worked back in the day but it looks like Object.create is changed. I would go for the copy-constructor way like @user166390 said in the comments.
The reason I necromanced this post is because I needed such implementation.

Nowadays we can use Object.assign (credits to @SayanPal solution) & ES6 syntax:

class Person {
  constructor(obj) {
    obj && Object.assign(this, obj);
  }

  getFullName() {
    return `${this.lastName} ${this.firstName}`;
  }
}

Usage:

const newPerson = new Person(person1)
newPerson.getFullName() // -> Freeman Gordon

ES5 answer below

function Person(obj) {
    for(var prop in obj){
        // for safety you can use the hasOwnProperty function
        this[prop] = obj[prop];
    }
}

Usage:

var newPerson = new Person(person1);
console.log(newPerson.getFullName()); // -> Freeman Gordon

Using a shorter version, 1.5 liner:

function Person(){
    if(arguments[0]) for(var prop in arguments[0]) this[prop] = arguments[0][prop];
}

jsfiddle

Please try this:

<input class="col-xs-12 col-sm-8 col-sm-offset-2 col-md-8 col-md-offset-2" type="text" name="name" value="" placeholder="Your Name" style="background-color:blue;"/>

You basically put all the CSS inside the style part of the input tag and it works.

Something like

script > /dev/null 2>&1

This will prevent standard output and error output, redirecting them both to /dev/null.

Try this

SELECT DATEADD(MINUTE,HOW_MANY_MINUTES,TO_WHICH_TIME)

Here MINUTE is constant which indicates er are going to add/subtract minutes from TO_WHICH_TIME specifier. HOW_MANY_MINUTES is the interval by which we need to add minutes, if it is specified negative, time will be subtracted, else would be added to the TO_WHICH_TIME specifier and TO_WHICH_TIME is the original time to which you are adding MINUTE.

Hope this helps.

after installing the 1.7jdk from oracle, i changed my bash scripts to add:

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_13.jdk/Contents/Home

and then running java -version showed the right version.
