Select * from 
(
    Select ROW_NUMBER() OVER ( order by Id) as 'Row_Number', * 
    from tbl_Contact_Us
) as tbl
Where tbl.Row_Number = 5

You don't have to do everything in one line:

case 'SOME_ACTION':
  const newState = { ...state };
  newState.contents = 
    [
      newState.contents[0],
      {title: newState.contnets[1].title, text: action.payload}
    ];
  return newState

use jQuery.live() instead . Documentation here

e.g

$("mylink").live("click", function(event) { alert("new link clicked!");});

value_counts() is now a DataFrame method since pandas 1.1.0

I had the same problem on OSX OpenSSL 1.0.1i from Macports, and also had to specify CApath as a workaround (and as mentioned in the Ubuntu bug report, even an invalid CApath will make openssl look in the default directory). Interestingly, connecting to the same server using PHP's openssl functions (as used in PHPMailer 5) worked fine.

CriteriaBuilder criteriaBuilder = em.getCriteriaBuilder();
CriteriaQuery<Employee> criteriaQuery = criteriaBuilder.createQuery(Employee.class);
Root<Employee> empleoyeeRoot = criteriaQuery.from(Employee.class);

Subquery<Project> projectSubquery = criteriaQuery.subquery(Project.class);
Root<Project> projectRoot = projectSubquery.from(Project.class);
projectSubquery.select(projectRoot);

Expression<String> stringExpression = empleoyeeRoot.get(Employee_.ID);
Predicate predicateIn = stringExpression.in(projectSubquery);

criteriaQuery.select(criteriaBuilder.count(empleoyeeRoot)).where(predicateIn);

The problem here is that you have defined ID as a field in your data file when what you want is to just use an expression without any data from the data file. You can fix this by defining ID as an expression (or a sequence in this case)

ID EXPRESSION "ID_SEQ.nextval"

or

ID SEQUENCE(count)

See: http://docs.oracle.com/cd/B28359_01/server.111/b28319/ldr_field_list.htm#i1008234 for all options

I had the same problem. I followed these steps (in this exact order, this is VERY important):

1. Create child component in the "app.module.ts"
2. Build the application
3. Create parent component
4. Build the application
5. Create HTML archive
6. Build the application

This happens mainly because Angular won't build those modules in the correct order, i.e before the HTML.

e.g My code:

  <mat-toolbar> <!-- 2 -->
    <button mat-icon-button class="example-icon" aria-label="Example icon-button with menu icon">
      <mat-icon>favorite</mat-icon> <!-- 1 -->
    </button>
    <span>My App</span>
    <span class="example-spacer"></span>
    <button mat-icon-button class="example-icon favorite-icon" aria-label="Example icon-button with heart icon">
    </button>
    <button mat-icon-button class="example-icon" aria-label="Example icon-button with share icon">
    </button>
  </mat-toolbar>

Yes, you can configure the Spring servlet context xml file to define your beans (i.e., classes), so that it can do the automatic injection for you. However, do note, that you have to do other configurations to have Spring up and running and the best way to do that, is to follow a tutorial ground up.

Once you have your Spring configured probably, you can do the following in your Spring servlet context xml file for Example 1 above to work (please replace the package name of com.movies to what the true package name is and if this is a 3rd party class, then be sure that the appropriate jar file is on the classpath) :

<beans:bean id="movieFinder" class="com.movies.MovieFinder" />

or if the MovieFinder class has a constructor with a primitive value, then you could something like this,

<beans:bean id="movieFinder" class="com.movies.MovieFinder" >
    <beans:constructor-arg value="100" />
</beans:bean>

or if the MovieFinder class has a constructor expecting another class, then you could do something like this,

<beans:bean id="movieFinder" class="com.movies.MovieFinder" >
    <beans:constructor-arg ref="otherBeanRef" />
</beans:bean>

...where 'otherBeanRef' is another bean that has a reference to the expected class.

I'd like to understand how the respond_to block actually works. What type of variable is format? Are .html and .json methods of the format object?

In order to understand what format is, you could first look at the source for respond_to, but quickly you'll find that what really you need to look at is the code for retrieve_response_from_mimes.

From here, you'll see that the block that was passed to respond_to (in your code), is actually called and passed with an instance of Collector (which within the block is referenced as format). Collector basically generates methods (I believe at Rails start-up) based on what mime types rails knows about.

So, yes, the .html and .json are methods defined (at runtime) on the Collector (aka format) class.

You can just make sure your css file parses AFTER boostrap.css , like so:

<link href="css/bootstrap.css" rel="stylesheet">
<link href="css/myFile.css" rel="stylesheet">

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

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

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

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

I put the data starting on row 5:

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

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

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

The only built-in way to "downgrade" a database from one SQL Server version to a lower one is the hard way: Script out the whole database, schema and data, then execute the script on the target server.

This is do-able but tends to be brutal.

and the version to work on the array type:

select
  array_to_string(
    array(select distinct unnest(zip_codes) from table),
    ', '
);

Or maybe

 background: transparent !important;
 color: #ffffff;

I would like to plug my own graph python library: graph-tool.

It is very fast, since it is implemented in C++ with the Boost Graph Library, and it contains lots of algorithms and extensive documentation.

If you are using Sass:

$card-column-sizes: (
    xs: 2,
    sm: 3,
    md: 4,
    lg: 5,
);

@each $breakpoint-size, $column-count in $card-column-sizes {
    @include media-breakpoint-up($breakpoint-size) {
      .card-columns {
        column-count: $column-count;
        column-gap: 1.25rem;

        .card {
          display: inline-block;
          width: 100%; // Don't let them exceed the column width
        }

    }
}

nawk:

$ nawk 'BEGIN{print srand()}'

• Works even on old versions of Solaris and probably other UNIX systems, where '''date +%s''' isn't implemented
• Doesn't work on Linux and other distros where the posix tools have been replaced with the GNU versions (nawk -> gawk etc.)
• Pretty unintuitive but definitelly amusing :-)

I assume that you have some sort of List component and some sort of Item component. The way I did it in one project was to let the item know if it was active or not; the item would ask the list to scroll it into view if necessary. Consider the following pseudocode:

class List extends React.Component {
  render() {
    return <div>{this.props.items.map(this.renderItem)}</div>;
  }

  renderItem(item) {
    return <Item key={item.id} item={item}
                 active={item.id === this.props.activeId}
                 scrollIntoView={this.scrollElementIntoViewIfNeeded} />
  }

  scrollElementIntoViewIfNeeded(domNode) {
    var containerDomNode = React.findDOMNode(this);
    // Determine if `domNode` fully fits inside `containerDomNode`.
    // If not, set the container's scrollTop appropriately.
  }
}

class Item extends React.Component {
  render() {
    return <div>something...</div>;
  }

  componentDidMount() {
    this.ensureVisible();
  }

  componentDidUpdate() {
    this.ensureVisible();
  }

  ensureVisible() {
    if (this.props.active) {
      this.props.scrollIntoView(React.findDOMNode(this));
    }
  }
}

A better solution is probably to make the list responsible for scrolling the item into view (without the item being aware that it's even in a list). To do so, you could add a ref attribute to a certain item and find it with that:

class List extends React.Component {
  render() {
    return <div>{this.props.items.map(this.renderItem)}</div>;
  }

  renderItem(item) {
    var active = item.id === this.props.activeId;
    var props = {
      key: item.id,
      item: item,
      active: active
    };
    if (active) {
      props.ref = "activeItem";
    }
    return <Item {...props} />
  }

  componentDidUpdate(prevProps) {
    // only scroll into view if the active item changed last render
    if (this.props.activeId !== prevProps.activeId) {
      this.ensureActiveItemVisible();
    }
  }

  ensureActiveItemVisible() {
    var itemComponent = this.refs.activeItem;
    if (itemComponent) {
      var domNode = React.findDOMNode(itemComponent);
      this.scrollElementIntoViewIfNeeded(domNode);
    }
  }

  scrollElementIntoViewIfNeeded(domNode) {
    var containerDomNode = React.findDOMNode(this);
    // Determine if `domNode` fully fits inside `containerDomNode`.
    // If not, set the container's scrollTop appropriately.
  }
}

If you don't want to do the math to determine if the item is visible inside the list node, you could use the DOM method scrollIntoView() or the Webkit-specific scrollIntoViewIfNeeded, which has a polyfill available so you can use it in non-Webkit browsers.

I've found it helpful to go into my "tmp" folder and delete all hanging rsession files. This usually frees any memory that seems to be "stuck".

As Mark C points out, you can use the MSXML Base64 encoding functionality as described here.

I prefer late binding because it's easier to deploy, so here's the same function that will work without any VBA references:

Function EncodeBase64(text As String) As String
  Dim arrData() As Byte
  arrData = StrConv(text, vbFromUnicode)

  Dim objXML As Variant
  Dim objNode As Variant

  Set objXML = CreateObject("MSXML2.DOMDocument")
  Set objNode = objXML.createElement("b64")

  objNode.dataType = "bin.base64"
  objNode.nodeTypedValue = arrData
  EncodeBase64 = objNode.text

  Set objNode = Nothing
  Set objXML = Nothing
End Function

They don't have the same structure... I can guarantee they are different

I know you've already created it... There is already an object named ‘tbltable1’ in the database

What you may want is this (which also fixes your other issue):

Drop table tblTable1

select * into tblTable1 from tblTable1_Link

You can use scanf function to read string

scanf("%[^\n]",name);

i don't know about other better options to receive string,

You can put your servers in the default_step group and those vars will apply to it:

# inventory file
[default_step]
prod2
web_v2

Then just move your default_step.yml file to group_vars/default_step.yml.

As a quick and very scoped solution:

Task.Result

Both Task.Result and Task.Wait won't allow to improving scalability when used with I/O, as they will cause the calling thread to stay blocked waiting for the I/O to end.

When you call .Result on an incomplete Task, the thread executing the method has to sit and wait for the task to complete, which blocks the thread from doing any other useful work in the meantime. This negates the benefit of the asynchronous nature of the task.

Visual Studio 2015 does include Xamarin Starter edition https://xamarin.com/starter

Xamarin Starter is free and allows developers to build and publish simple apps with the following limitations:

• Contain no more than 128k of compiled user code (IL)
• Do NOT call out to native third party libraries (i.e., developers may not P/Invoke into C/C++/Objective-C/Java)
• Built using Xamarin.iOS / Xamarin.Android (NOT Xamarin.Forms)

Xamarin Starter installs automatically with Visual Studio 2015, and works with VS 2012, 2013, and 2015 (including Community Editions). When your app outgrows Starter, you will be offered the opportunity to upgrade to a paid subscription, which you can learn more about here: https://store.xamarin.com/

How to allocate a contiguous multidimensional array in GNU C++? There's a GNU extension that allows the "standard" syntax to work.

It seems the problem come from operator new []. Make sure you use operator new instead :

double (* in)[n][n] = new (double[m][n][n]);  // GNU extension

And that's all : you get a C-compatible multidimensional array...

Setting git proxy on terminal

if

• you do not want set proxy for each of your git projects manually, one by one
• always want to use same proxy for all your projects

Set it globally once

git config --global http.proxy username:password@proxy_url:proxy_port
git config --global https.proxy username:password@proxy_url:proxy_port

if you want to set proxy for only one git project (there may be some situations where you may not want to use same proxy or any proxy at all for some git connections)

//go to project root
cd /bla_bla/project_root
//set proxy for both http and https
git config http.proxy username:password@proxy_url:proxy_port
git config https.proxy username:password@proxy_url:proxy_port

if you want to display current proxy settings

git config --list 

if you want to remove proxy globally

git config --global --unset http.proxy
git config --global --unset https.proxy

if you want to remove proxy for only one git root

//go to project root
cd /bla-bla/project_root
git config --unset http.proxy
git config --unset https.proxy

cURL-less you can use in php5

$url = 'URL';
$data = array('field1' => 'value', 'field2' => 'value');
$options = array(
        'http' => array(
        'header'  => "Content-type: application/x-www-form-urlencoded\r\n",
        'method'  => 'POST',
        'content' => http_build_query($data),
    )
);

$context  = stream_context_create($options);
$result = file_get_contents($url, false, $context);
var_dump($result);

I found out it was:

$ git fetch upstream
$ git merge upstream/master

another way to do this operation:

public class TimeUtils {

    /**
     * @param timestamp
     * @return
     */
    public static boolean isToday(long timestamp) {
        Calendar now = Calendar.getInstance();
        Calendar timeToCheck = Calendar.getInstance();
        timeToCheck.setTimeInMillis(timestamp);
        return (now.get(Calendar.YEAR) == timeToCheck.get(Calendar.YEAR)
                && now.get(Calendar.DAY_OF_YEAR) == timeToCheck.get(Calendar.DAY_OF_YEAR));
    }

}

As Kris mentions, you can use the $resource service to interact with the server, but I get the impression you are beginning your journey with Angular - I was there last week - so I recommend to start experimenting directly with the $http service. In this case you can call its get method.

If you have the following JSON

[{ "text":"learn angular", "done":true },
 { "text":"build an angular app", "done":false},
 { "text":"something", "done":false },
 { "text":"another todo", "done":true }]

You can load it like this

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

App.controller('TodoCtrl', function($scope, $http) {
  $http.get('todos.json')
       .then(function(res){
          $scope.todos = res.data;                
        });
});

The get method returns a promise object which first argument is a success callback and the second an error callback.

When you add $http as a parameter of a function Angular does it magic and injects the $http resource into your controller.

I've put some examples here

• http://plnkr.co/edit/Wuc6M7?p=preview
• https://gist.github.com/3938567

You need to use the await keyword when use async and your function return type should be generic Here is an example with return value:

public async Task<object> MethodName()
{
    return await Task.FromResult<object>(null);
}

Here is an example with no return value:

public async Task MethodName()
{
    await Task.CompletedTask;
}

The problem is that C++ is a statically-typed language, meaning that if something is declared as a string, it's a string, and if something is declared as a double, it's a double. Unlike other languages like JavaScript or PHP, there is no way to automatically convert from a string to a numeric value because the conversion might not be well-defined. For example, if you try converting the string "Hi there!" to a double, there's no meaningful conversion. Sure, you could just set the double to 0.0 or NaN, but this would almost certainly be masking the fact that there's a problem in the code.

To fix this, don't buffer the file contents into a string. Instead, just read directly into the double:

double lol;
openfile >> lol;

This reads the value directly as a real number, and if an error occurs will cause the stream's .fail() method to return true. For example:

double lol;
openfile >> lol;

if (openfile.fail()) {
    cout << "Couldn't read a double from the file." << endl;
}

Set the Format to Custom and then specify the format:

dateTimePicker1.Format = DateTimePickerFormat.Custom;
dateTimePicker1.CustomFormat = "MM/dd/yyyy hh:mm:ss";  

or however you want to lay it out. You could then type in directly the date/time. If you use MMM, you'll need to use the numeric value for the month for entry, unless you write some code yourself for that (e.g., 5 results in May)

Don't know about the picker for date and time together. Sounds like a custom control to me.

The trick for me was not setting the height -- but instead setting the minHeight. This must be applied to the root view of whatever layout your custom adapter is using to render each row.

Well, there's nothing really that can pass through that, other than % wildcard. It could be dangerous if you were using LIKE statement as attacker could put just % as login if you don't filter that out, and would have to just bruteforce a password of any of your users. People often suggest using prepared statements to make it 100% safe, as data can't interfere with the query itself that way. But for such simple queries it probably would be more efficient to do something like $login = preg_replace('/[^a-zA-Z0-9_]/', '', $login);

Another useful property of the cross product is that its magnitude is related to the sine of the angle between the two vectors:

| a x b | = |a| . |b| . sine(theta)

or

sine(theta) = | a x b | / (|a| . |b|)

So, in implementation 1 above, if a and b are known in advance to be unit vectors then the result of that function is exactly that sine() value.

I actually had an issue where my db was pretty much locked by the processes and a race condition with them, by the time I got one command executed refreshed and they had it locked again... I had to run the following commands back to back in SSMS and got me offline and from there I did my restore and came back online just fine, the two queries where:

First ran:

USE master
GO

DECLARE @kill varchar(8000) = '';
SELECT @kill = @kill + 'kill ' + CONVERT(varchar(5), spid) + ';'
FROM master..sysprocesses 
WHERE dbid = db_id('<yourDbName>')

EXEC(@kill);

Then immediately after (in second query window):

USE master ALTER DATABASE <yourDbName> SET OFFLINE WITH ROLLBACK IMMEDIATE

Did what I needed and then brought it back online. Thanks to all who wrote these pieces out for me to combine and solve my problem.

Worked for me below code:

DateTime date = DateTime.Parse(this.Text, CultureInfo.CreateSpecificCulture("fr-FR"));

Namespace

using System.Globalization;

@qbzenker provided the most idiomatic method IMO

Here are a few alternatives:

In [28]: df.query('Col2 != Col2') # Using the fact that: np.nan != np.nan
Out[28]:
   Col1  Col2  Col3
1     0   NaN   0.0

In [29]: df[np.isnan(df.Col2)]
Out[29]:
   Col1  Col2  Col3
1     0   NaN   0.0

It only seems to because that is what it is printing out. But actually, you shouldn't write the logic this way. This is equivalent:

insert into errortable (dateupdated, table1id)
    values (sysdate, 1083);

It seems silly to convert the system date to a string just to convert it back to a date.

If you want to see the full date, then you can do:

select TO_CHAR(dateupdated, 'YYYY-MM-DD HH24:MI:SS'), table1id
from errortable;

run command creates a container from the image and then starts the root process on this container. Running it with run --rm flag would save you the trouble of removing the useless dead container afterward and would allow you to ignore the existence of docker start and docker remove altogether.

run command does a few different things:

docker run --name dname image_name bash -c "whoami"

1. Creates a Container from the image. At this point container would have an id, might have a name if one is given, will show up in docker ps
2. Starts/executes the root process of the container. In the code above that would execute bash -c "whoami". If one runs docker run --name dname image_name without a command to execute container would go into stopped state immediately.
3. Once the root process is finished, the container is stopped. At this point, it is pretty much useless. One can not execute anything anymore or resurrect the container. There are basically 2 ways out of stopped state: remove the container or create a checkpoint (i.e. an image) out of stopped container to run something else. One has to run docker remove before launching container under the same name.

How to remove container once it is stopped automatically? Add an --rm flag to run command:

docker run --rm --name dname image_name bash -c "whoami"

How to execute multiple commands in a single container? By preventing that root process from dying. This can be done by running some useless command at start with --detached flag and then using "execute" to run actual commands:

docker run --rm -d --name dname image_name tail -f /dev/null
docker exec dname bash -c "whoami"
docker exec dname bash -c "echo 'Nnice'"

Why do we need docker stop then? To stop this lingering container that we launched in the previous snippet with the endless command tail -f /dev/null.

Use

$items[] = $username;

If you are using SQL Server 2008 or later

select convert(date, getdate())

Otherwise

select convert(varchar(10), getdate(),120)

You can use virtualenv --clear. which won't install any packages, then install the ones you want.

Maybe you could try:

There are several ways you can achieve this based on the approach you take. For reactive approach, you can pass the default value to the constructor of the FormControl(import from @angular/forms)

this.randomForm = new FormGroup({
      'amateur': new FormControl(false),
});

Instead of true or false value, yes you can send variable name as well like FormControl(this.booleanVariable)

In template driven approach you can use 1 way binding [ngModel]="this.booleanVariable" or 2 way binding [(ngModel)]="this.booleanVariable" like this

<mat-checkbox
     name="controlName"
     [(ngModel)]="booleanVariable">
     {{col.title}}
</mat-checkbox>

You can also use the checked directive provided by angular material and bind in similar manner

The ASPX code will look something like this:

 <asp:RadioButtonList ID="rblist1" runat="server">

    <asp:ListItem Text ="Item1" Value="1" />
    <asp:ListItem Text ="Item2" Value="2" />
    <asp:ListItem Text ="Item3" Value="3" />
    <asp:ListItem Text ="Item4" Value="4" />

    </asp:RadioButtonList>

    <asp:Button ID="btn1" runat="server" OnClick="Button1_Click" Text="select value" />

And the code behind:

protected void Button1_Click(object sender, EventArgs e)
        {
            string selectedValue = rblist1.SelectedValue;
            Response.Write(selectedValue);
        }

I had a similiar problem that caused me some hours of headache.

My repository method was:

public List<ResultClass> findAllByTypeAndObjects(String type, List<Object> objects);

I got the error, that the property type was not found for type ResultClass.

The solution was, that jpa/hibernate does not support plurals? Nevertheless, removing the 's' solved the problem:

public List<ResultClass> findAllByTypeAndObject(String type, List<Object>

Just follow closely the chain of events.

• Grab 10
• Grab 20
• Grab 30
• Grab EOF

Look at the second-to-last iteration. You grabbed 30, then carried on to check for EOF. You haven't reached EOF because the EOF mark hasn't been read yet ("binarically" speaking, its conceptual location is just after the 30 line). Therefore you carry on to the next iteration. x is still 30 from previous iteration. Now you read from the stream and you get EOF. x remains 30 and the ios::eofbit is raised. You output to stderr x (which is 30, just like in the previous iteration). Next you check for EOF in the loop condition, and this time you're out of the loop.

Try this:

while (true) {
    int x;
    iFile >> x;
    if( iFile.eof() ) break;
    cerr << x << endl;
}

By the way, there is another bug in your code. Did you ever try to run it on an empty file? The behaviour you get is for the exact same reason.

I wrote a plugin that implements update_without_callbacks in Rails 3:

http://github.com/dball/skip_activerecord_callbacks

The right solution, I think, is to rewrite your models to avoid callbacks in the first place, but if that's impractical in the near term, this plugin may help.

If you're using python 3.4.1 then you get a different answer to your question.

list = [1,2,3]
id(list[0])
id(list[1])
id(list[2])

returns:

1705950792   
1705950808  # increased by 16   
1705950824  # increased by 16

The integers -5 to 256 have a constant id, and on finding it multiple times its id does not change, unlike all other numbers before or after it that have different id's every time you find it. The numbers from -5 to 256 have id's in increasing order and differ by 16.

The number returned by id() function is a unique id given to each item stored in memory and it is analogy wise the same as the memory location in C.

I found the solution this problem very simple and which works always. It is change the eclipse setting file.

For example (change HTML indentation size):

1. Found org.eclipse.wst.html.core.prefs file which should be in your_workspace/.metadata/.plugins/org.eclipse.core.runtime/.settings/
2. Add/Change to line in file:

indentationChar=space

indentationSize=4

Start with looking up the z-value for your desired confidence interval from a look-up table. The confidence interval is then mean +/- z*sigma, where sigma is the estimated standard deviation of your sample mean, given by sigma = s / sqrt(n), where s is the standard deviation computed from your sample data and n is your sample size.

Something like this could be used, and still maintaining meanings of return (to return control signals) and echo (to return information) and logging statements (to print debug/info messages).

v_verbose=1
v_verbose_f=""         # verbose file name
FLAG_BGPID=""

e_verbose() {
        if [[ $v_verbose -ge 0 ]]; then
                v_verbose_f=$(tempfile)
                tail -f $v_verbose_f &
                FLAG_BGPID="$!"
        fi
}

d_verbose() {
        if [[ x"$FLAG_BGPID" != "x" ]]; then
                kill $FLAG_BGPID > /dev/null
                FLAG_BGPID=""
                rm -f $v_verbose_f > /dev/null
        fi
}

init() {
        e_verbose

        trap cleanup SIGINT SIGQUIT SIGKILL SIGSTOP SIGTERM SIGHUP SIGTSTP
}

cleanup() {
        d_verbose
}

init

fun1() {
    echo "got $1" >> $v_verbose_f
    echo "got $2" >> $v_verbose_f
    echo "$(( $1 + $2 ))"
    return 0
}

a=$(fun1 10 20)
if [[ $? -eq 0 ]]; then
    echo ">>sum: $a"
else
    echo "error: $?"
fi
cleanup

In here, I'm redirecting debug messages to separate file, that is watched by tail, and if there is any changes then printing the change, trap is used to make sure that background process always ends.

This behavior can also be achieved using redirection to /dev/stderr, But difference can be seen at the time of piping output of one command to input of other command.

It seems all answers here suggest some sort of versioning in the naming scheme, which has its downsides.

Browsers should be well aware of what to cache and what not to cache by reading the web server's response, in particular the HTTP headers - for how long is this resource valid? Was this resource updated since I last retrieved it? etc.

If things are configured 'correctly', just updating the files of your application should (at some point) refresh the browser's caches. You can for example configure your web server to tell the browser to never cache files (which is a bad idea).

A more in-depth explanation of how that works is in How Web Caches Work.

if anyone gets in here again this worked for me...

"aoColumnDefs": [{ "bVisible": false, "aTargets": [0] }]

First things is this is only for advanced developers persons Who all are now beginner to php dont use this function if you are using the huge project in core php use this function

function displayAllRecords($serverName, $userName, $password, $databaseName,$sqlQuery='')
{
    $databaseConnectionQuery =  mysqli_connect($serverName, $userName, $password, $databaseName);
    if($databaseConnectionQuery === false)
    {
        die("ERROR: Could not connect. " . mysqli_connect_error());
        return false;
    }

    $resultQuery = mysqli_query($databaseConnectionQuery,$sqlQuery);
    $fetchFields = mysqli_fetch_fields($resultQuery);
    $fetchValues = mysqli_fetch_fields($resultQuery);

    if (mysqli_num_rows($resultQuery) > 0) 
    {           

        echo "<table class='table'>";
        echo "<tr>";
        foreach ($fetchFields as $fetchedField)
         {          
            echo "<td>";
            echo "<b>" . $fetchedField->name . "<b></a>";
            echo "</td>";
        }       
        echo "</tr>";
        while($totalRows = mysqli_fetch_array($resultQuery)) 
        {           
            echo "<tr>";                                
            for($eachRecord = 0; $eachRecord < count($fetchValues);$eachRecord++)
            {           
                echo "<td>";
                echo $totalRows[$eachRecord];
                echo "</td>";               
            }
            echo "<td><a href=''><button>Edit</button></a></td>";
            echo "<td><a href=''><button>Delete</button></a></td>";
            echo "</tr>";           
        } 
        echo "</table>";        

    } 
    else
    {
      echo "No Records Found in";
    }
}

All set now Pass the arguments as For Example

$queryStatment = "SELECT * From USERS "; $testing = displayAllRecords('localhost','root','root@123','email',$queryStatment); echo $testing;

Here

localhost indicates Name of the host,

root indicates the username for database

root@123 indicates the password for the database

$queryStatment for generating Query

hope it helps

Nitin is correct - the issue is actually in the MDB2 code.

According to Replacement for PEAR: MDB2 on PHP 5.3 you can update to the SVN version of MDB2 for a version which is PHP5.3 compatible.

As that answer was given in March 2010, and http://pear.php.net/package/MDB2/ shows a release some months later, I expect the current version of MDB2 will solve the issue also.

Using split()

Snippet :

var data =$('#date').text();_x000D_
var arr = data.split('/');_x000D_
$("#date").html("<span>"+arr[0] + "</span></br>" + arr[1]+"/"+arr[2]);   

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="date">23/05/2013</div>

Fiddle

When you split this string ---> 23/05/2013 on /

var myString = "23/05/2013";
var arr = myString.split('/');

you'll get an array of size 3

arr[0] --> 23
arr[1] --> 05
arr[2] --> 2013

Use Ctrl + K + 0 to fold all and Ctrl + K + J to unfold all.

I would recommend overriding the onResume() method in activity number 1, and in there include code to refresh your array adapter, this is done by using [yourListViewAdapater].notifyDataSetChanged();

Read this if you are having trouble refreshing the list: Android List view refresh

This is the correct syntax:

String arlist1 [] = { "value1`", "value2", "value3" };
JSONArray jsonArray1 = new JSONArray(arlist1);

In my experience, the "I" convention applies to interfaces that are intended to provide a contract to a class, particularly when the interface itself is not an abstract notion of the class.

For example, in your case, I'd only expect to see IUser if the only user you ever intend to have is User. If you plan to have different types of users - NoviceUser, ExpertUser, etc. - I would expect to see a User interface (and, perhaps, an AbstractUser class that implements some common functionality, like get/setName()).

I would also expect interfaces that define capabilities - Comparable, Iterable, etc. - to be named like that, and not like IComparable or IIterable.

As others have answered, this breaks because .ToString fails to translate to relevant SQL on the way into the database.

However, Microsoft provides the SqlFunctions class that is a collection of methods that can be used in situations like this.

For this case, what you are looking for here is SqlFunctions.StringConvert:

from p in context.pages
where  p.Serial == SqlFunctions.StringConvert((double)item.Key.Id)
select p;

Good when the solution with temporary variables is not desirable for whatever reasons.

Similar to SqlFunctions you also have the EntityFunctions (with EF6 obsoleted by DbFunctions) that provides a different set of functions that also are data source agnostic (not limited to e.g. SQL).

I was stuck on this for a long time. After a lot of tries I was able to configured it properly.

There can be different reasons of raising the error. I am trying to provide the reason and the solution to overcome from that situation.

1. 6379 Port is not allowed by ufw firewall.

   Solution: type following command sudo ufw allow 6379

2. The issue can be related to permission of redis user. May be redis user doesn't have permission of modifying necessary redis directories. The redis user should have permissions in the following directories:

   • /var/lib/redis
   • /var/log/redis
   • /run/redis
   • /etc/redis

   To give the owner permission to redis user, type the following commands:

   • sudo chown -R redis:redis /var/lib/redis
   • sudo chown -R redis:redis /var/log/redis
   • sudo chown -R redis:redis /run/redis
   • sudo chown -R redis:redis /etc/redis.

   Now restart redis-server by following command:

   sudo systemctl restart redis-server

Hope this will be helpful for somebody.

add some id for an input

var multi = product(2,3);
document.getElementById('id').value=multi;

DBQuery.shellBatchSize = 300

will do.

I believe what you are looking for is "git restore".

The easiest way is to remove the file locally, and then execute the git restore command for that file:

$ rm file.txt
$ git restore file.txt 

If you want to use regular expressions, then try:

ls -c | grep "^d" | wc -l

Because you can ask the server to prepend a prefix to the returned JSON object. E.g

function_prefix(json_object);

in order for the browser to eval "inline" the JSON string as an expression. This trick makes it possible for the server to "inject" javascript code directly in the Client browser and this with bypassing the "same origin" restrictions.

In other words, you can achieve cross-domain data exchange.

Normally, XMLHttpRequest doesn't permit cross-domain data-exchange directly (one needs to go through a server in the same domain) whereas:

<script src="some_other_domain/some_data.js&prefix=function_prefix>` one can access data from a domain different than from the origin.

Also worth noting: even though the server should be considered as "trusted" before attempting that sort of "trick", the side-effects of possible change in object format etc. can be contained. If a function_prefix (i.e. a proper js function) is used to receive the JSON object, the said function can perform checks before accepting/further processing the returned data.

Here is another solution:

SELECT Isnull(Nullif(listing.offertext, ''), company.offertext) AS offer_text, 
FROM   tbl_directorylisting listing 
       INNER JOIN tbl_companymaster company 
         ON listing.company_id = company.company_id

Easy way to get JSON especially for Android SDK 23:

public class MainActivity extends AppCompatActivity {

Button btnHit;
TextView txtJson;
ProgressDialog pd;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    btnHit = (Button) findViewById(R.id.btnHit);
    txtJson = (TextView) findViewById(R.id.tvJsonItem);

    btnHit.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            new JsonTask().execute("Url address here");
        }
    });


}


private class JsonTask extends AsyncTask<String, String, String> {

    protected void onPreExecute() {
        super.onPreExecute();

        pd = new ProgressDialog(MainActivity.this);
        pd.setMessage("Please wait");
        pd.setCancelable(false);
        pd.show();
    }

    protected String doInBackground(String... params) {


        HttpURLConnection connection = null;
        BufferedReader reader = null;

        try {
            URL url = new URL(params[0]);
            connection = (HttpURLConnection) url.openConnection();
            connection.connect();


            InputStream stream = connection.getInputStream();

            reader = new BufferedReader(new InputStreamReader(stream));

            StringBuffer buffer = new StringBuffer();
            String line = "";

            while ((line = reader.readLine()) != null) {
                buffer.append(line+"\n");
                Log.d("Response: ", "> " + line);   //here u ll get whole response...... :-) 

            }

            return buffer.toString();


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

If you want to get a floating point value with two decimal places limited at the time of calling input,

Check this out ~

a = eval(format(float(input()), '.2f'))   # if u feed 3.1415 for 'a'.
print(a)                                  # output 3.14 will be printed.

After Python 3.0 onward, print is no longer just a statement, its a function instead. and is included in PEP 3105.

Also I think the Python 3.0 package has still these special functionality. Lets see its usability through a traditional "Pyramid program" in Python:

from __future__ import print_function

class Star(object):
    def __init__(self,count):
        self.count = count

    def start(self):
        for i in range(1,self.count):
            for j in range (i): 
                print('*', end='') # PEP 3105: print As a Function 
            print()

a = Star(5)
a.start()

Output:
*
**
***
****

If we use normal print function, we won't be able to achieve the same output, since print() comes with a extra newline. So every time the inner for loop execute, it will print * onto the next line.

Mabey you only need:

Step one:

grant all privileges on *.* to 'user'@'IP' identified by 'password';

or

grant all privileges on *.* to 'user'@'%' identified by 'password';

Step two:

sudo ufw allow 3306

Step three:

sudo service mysql restart

Programming the Mandelbrot is easy.
My quick-n-dirty code is below (not guaranteed to be bug-free, but a good outline).

Here's the outline: The Mandelbrot-set lies in the Complex-grid completely within a circle with radius 2.

So, start by scanning every point in that rectangular area. Each point represents a Complex number (x + yi). Iterate that complex number:

[new value] = [old-value]^2 + [original-value] while keeping track of two things:

1.) the number of iterations

2.) the distance of [new-value] from the origin.

If you reach the Maximum number of iterations, you're done. If the distance from the origin is greater than 2, you're done.

When done, color the original pixel depending on the number of iterations you've done. Then move on to the next pixel.

public void MBrot()
{
    float epsilon = 0.0001; // The step size across the X and Y axis
    float x;
    float y;
    int maxIterations = 10; // increasing this will give you a more detailed fractal
    int maxColors = 256; // Change as appropriate for your display.

    Complex Z;
    Complex C;
    int iterations;
    for(x=-2; x<=2; x+= epsilon)
    {
        for(y=-2; y<=2; y+= epsilon)
        {
            iterations = 0;
            C = new Complex(x, y);
            Z = new Complex(0,0);
            while(Complex.Abs(Z) < 2 && iterations < maxIterations)
            {
                Z = Z*Z + C;
                iterations++;
            }
            Screen.Plot(x,y, iterations % maxColors); //depending on the number of iterations, color a pixel.
        }
    }
}

Some details left out are:

1.) Learn exactly what the Square of a Complex number is and how to calculate it.

2.) Figure out how to translate the (-2,2) rectangular region to screen coordinates.

Expanding on the answer from Grin/Dan Abramov, this works across multiple input types. Tested in React >= 15.5

const inputTypes = [
    window.HTMLInputElement,
    window.HTMLSelectElement,
    window.HTMLTextAreaElement,
];

export const triggerInputChange = (node, value = '') => {

    // only process the change on elements we know have a value setter in their constructor
    if ( inputTypes.indexOf(node.__proto__.constructor) >-1 ) {

        const setValue = Object.getOwnPropertyDescriptor(node.__proto__, 'value').set;
        const event = new Event('input', { bubbles: true });

        setValue.call(node, value);
        node.dispatchEvent(event);

    }

};

        var theNewScript = document.createElement("script");
        theNewScript.type = "text/javascript";
        theNewScript.src = "http://code.jquery.com/jquery.min.js";

        document.getElementsByTagName("head")[0].appendChild(theNewScript);

    alert('here' + jsonData.length.toString());
    GDNUtils.loadJquery();

    $.each(jsonData, function (i, v) {

        if (v[keytoSearch] == valuetoSearch) {
            alert(v[keytoGet].toString());

            return;
        }
    });



};




GDNUtils.searchJson = function (jsonData, keytoSearch, valuetoSearch) {
    GDNUtils.loadJquery();
    alert('here' + jsonData.length.toString());
    GDNUtils.loadJquery();
    var row;
    $.each(jsonData, function (i, v) {

        if (v[keytoSearch] == valuetoSearch) {

    });

    return row;

The iPhoneOS does capture onscroll events, except not the way you may expect.

One-finger panning doesn’t generate any events until the user stops panning—an onscroll event is generated when the page stops moving and redraws—as shown in Figure 6-1.

Similarly, scroll with 2 fingers fires onscroll only after you've stopped scrolling.

The usual way of installing the handler works e.g.

window.addEventListener('scroll', function() { alert("Scrolled"); });
// or
$(window).scroll(function() { alert("Scrolled"); });
// or
window.onscroll = function() { alert("Scrolled"); };
// etc 

(See also https://developer.apple.com/library/content/documentation/AppleApplications/Reference/SafariWebContent/HandlingEvents/HandlingEvents.html)

What you want to do is separate the content of the table from the header of the table. You want only the <th> elements to be scrolled. You can easily define this separation in HTML with the <tbody> and the <thead> elements.
Now the header and the body of the table are still connected to each other, they will still have the same width (and same scroll properties). Now to let them not 'work' as a table anymore you can set the display: block. This way <thead> and <tbody> are separated.

table tbody, table thead
{
    display: block;
}

Now you can set the scroll to the body of the table:

table tbody 
{
   overflow: auto;
   height: 100px;
}

And last, because the <thead> doesn't share the same width as the body anymore, you should set a static width to the header of the table:

th
{
    width: 72px;
}

You should also set a static width for <td>. This solves the issue of the unaligned columns.

td
{
    width: 72px;
}

<tr>
     <th>head1</th>
     <th>head2</th>
     <th>head3</th>
     <th>head4</th>
</tr>

I hope this is what you meant.

jsFiddle

Addendum

If you would like to have more control over the column widths, have them to vary in width between each other, and course keep the header and body columns aligned, you can use the following example:

    table th:nth-child(1), td:nth-child(1) { min-width: 50px;  max-width: 50px; }
    table th:nth-child(2), td:nth-child(2) { min-width: 100px; max-width: 100px; }
    table th:nth-child(3), td:nth-child(3) { min-width: 150px; max-width: 150px; }
    table th:nth-child(4), td:nth-child(4) { min-width: 200px; max-width: 200px; }

You can't have duplicate ids. Ids are supposed to be unique. You might want to use a specialized class instead.

INSERT INTO `table` ( `data` , `date` ) VALUES('".$data."',NOW()+INTERVAL 1 DAY);

in my main script detectiveROB.py file i need call passGen function which generate password hash and that functions is under modules\passwordGen.py

The quickest and easiest solution for me is

Below is my directory structure

So in detectiveROB.py i have import my function with below syntax

from modules.passwordGen import passGen

You do not need to insert the current timestamp manually as MySQL provides this facility to store it automatically. When the MySQL table is created, simply do this:

• select TIMESTAMP as your column type
• set the Default value to CURRENT_TIMESTAMP
• then just insert any rows into the table without inserting any values for the time column

You'll see the current timestamp is automatically inserted when you insert a row. Please see the attached picture.

I use the get_queried_object function to get the current category on a category.php template page.

$current_category = get_queried_object();

Jordan Eldredge is right, get_the_category is not suitable here.

I use this to open a workbook and then copy that workbook's data to the template.

Private Sub CommandButton24_Click()
Set Template = ActiveWorkbook
 With Application.FileDialog(msoFileDialogOpen)
    .InitialFileName = "I:\Group - Finance" ' Yu can select any folder you want
    .Filters.Clear
    .Title = "Your Title"
    If Not .Show Then
        MsgBox "No file selected.": Exit Sub
    End If
    Workbooks.OpenText .SelectedItems(1)

'The below is to copy the file into a new sheet in the workbook and paste those values in sheet 1

    Set myfile = ActiveWorkbook
    ActiveWorkbook.Sheets(1).Copy after:=ThisWorkbook.Sheets(1)
    myfile.Close
    Template.Activate
    ActiveSheet.Cells.Select
    Selection.Copy
    Sheets("Sheet1").Select
    Cells.Select
    ActiveSheet.Paste

End With

If you want to ensure a file is closed you should use the block form of File.open:

File.open("myFile.txt", "w") do |file|
  begin
    file << "#{content} \n"
  rescue
  #handle the error here
  end
end

get_current_user_id() will return the current user id (an integer), or will return 0 if the user is not logged in.

if (get_current_user_id()) {
   // display navbar here
}

More details here get_current_user_id().

You need to have a doGet method as:

public void doGet(HttpServletRequest request,
        HttpServletResponse response)
throws IOException, ServletException
{
    response.setContentType("text/html");
    PrintWriter out = response.getWriter();

    out.println("<html>");
    out.println("<head>");
    out.println("<title>Hola</title>");
    out.println("</head>");
    out.println("<body bgcolor=\"white\">");
    out.println("</body>");
    out.println("</html>");
}

A Linq one-liner for converting a byte array byteArrFilename read from a file to a pure ascii C-style zero-terminated string would be this: Handy for reading things like file index tables in old archive formats.

String filename = new String(byteArrFilename.TakeWhile(x => x != 0)
                              .Select(x => x < 128 ? (Char)x : '?').ToArray());

I use '?' as default char for anything not pure ascii here, but that can be changed, of course. If you want to be sure you can detect it, just use '\0' instead, since the TakeWhile at the start ensures that a string built this way cannot possibly contain '\0' values from the input source.

UPDATE Table SET Column = REPLACE(Column, char(9), '')

document.location was originally a read-only property, although Gecko browsers allow you to assign to it as well. For cross-browser safety, use window.location instead.

This is how I organized my application's static resources.

Java doesn't natively allow building of an exe, that would defeat its purpose of being cross-platform.

AFAIK, these are your options:

1. Make a runnable JAR. If the system supports it and is configured appropriately, in a GUI, double clicking the JAR will launch the app. Another option would be to write a launcher shell script/batch file which will start your JAR with the appropriate parameters

2. There also executable wrappers - see How can I convert my Java program to an .exe file?

If the performance is an issue, you can use this command in MS_DOS:

dir /OD >d:\dir.txt

This command generate a dir.txt file in **d:** root the have all files sorted by date. And then read the file from your code. Also, you add other filters by * and ?.

Kushagra Gour's solution does work (at least in Chrome and IE) and solves the original problem without having to use display: table; and display: table-cell;. See plunker: http://plnkr.co/edit/ULEgY1FDCsk8yiRTfOWU

Setting min-height: 100%; height: 1px; on the outer div causes its actual height to be at least 100%, as required. It also allows the inner div to correctly inherit the height.

public class lab {
public static void main(String args[]){
   Scanner input = new Scanner(System.in);
   System.out.println("Enter a string:");
   String s1;
   s1 = input.nextLine();
   int k = s1.length();
   char s2;
   s2=s1.charAt(k-1);
   s1=s2+s1+s2;
   System.out.println("The new string is\n" +s1);
   }
  }

Here's the output you'll get.

* Enter a string CAT The new string is TCATT *

It prints the the last character of the string to the first and last place. You can do it with any character of the String.

I was following this tutorial to host Font Awesome Pro 5.13 myself.

https://fontawesome.com/how-to-use/on-the-web/setup/hosting-font-awesome-yourself

For some reason I could not get <link href="%PUBLIC_URL%/font-awesome/all.min.css" rel="stylesheet"> to load webfonts that in turn resulted in only squares showing up. But when I used <script defer src="%PUBLIC_URL%/font-awesome/all.min.js"></script> everything started working. Both links were added in HTML <head>.

if your SQL query is this

SELECT id,name,roll FROM student WHERE name='Amit' AND roll='7'

then rawQuery will be

String query="SELECT id, name, roll FROM student WHERE name = ? AND roll = ?";
String[] selectionArgs = {"Amit","7"} 
db.rawQuery(query, selectionArgs);

The advantage of a wordier approach comes when your code is inside a 300,000 line project.

Using the action, as you have, there is no way to tell me what bool, int, and Blah are. If your action passed an object that defined the parameters then ok.

Using an EventHandler that wanted an EventArgs and if you would complete your DiagnosticsArgs example with getters for the properties that commented their purpose then you application would be more understandable. Also, please comment or fully name the arguments in the DiagnosticsArgs constructor.

In my component I need access to window.location.search. This is what I did in the Jest test:

Object.defineProperty(global, "window", {
  value: {
    location: {
      search: "test"
    }
  }
});

In case window properties must be different in different tests, we can put window mocking into a function, and make it writable in order to override for different tests:

function mockWindow(search, pathname) {
  Object.defineProperty(global, "window", {
    value: {
      location: {
        search,
        pathname
      }
    },
    writable: true
  });
}

And reset after each test:

afterEach(() => {
  delete global.window.location;
});

As long as your program die, then without detach or join of the thread, this error will occur. Without detaching and joining the thread, you should give endless loop after creating thread.

int main(){

std::thread t(thread,1);

while(1){}

//t.detach();
return 0;}

It is also interesting that, after sleeping or looping, thread can be detach or join. Also with this way you do not get this error.

Below example also shows that, third thread can not done his job before main die. But this error can not happen also, as long as you detach somewhere in the code. Third thread sleep for 8 seconds but main will die in 5 seconds.

void thread(int n) {std::this_thread::sleep_for (std::chrono::seconds(n));}

int main() {
std::cout << "Start main\n";
std::thread t(thread,1);
std::thread t2(thread,3);
std::thread t3(thread,8);
sleep(5);

t.detach();
t2.detach();
t3.detach();
return 0;}

It's not relative to performance...

You set async to false, when you need that ajax request to be completed before the browser passes to other codes:

<script>
    // ...
    $.ajax(... async: false ...); // Hey browser! first complete this request, 
                                  // then go for other codes

    $.ajax(...); // Executed after the completion of the previous async:false request.
</script>

I got it done by only encoding the output using utf-8. Here is the code example

new_tweets = api.GetUserTimeline(screen_name = user,count=200)
result = new_tweets[0]
try: text = result.text
except: text = ''

with open(file_name, 'a', encoding='utf-8') as f:
    writer = csv.writer(f)
    writer.writerows(text)

i.e: do not encode when collecting data from api, encode the output (print or write) only.

You can use format:

library(zoo)
x <- as.yearmon(Sys.time())
format(x,"%b")
[1] "Mar"
format(x,"%Y")
[1] "2012"

The simplest way is just to accept the incoming request, and pull out the variables you want in the Controller:

Route::get('search', ['as' => 'search', 'uses' => 'SearchController@search']);

and then in SearchController@search:

class SearchController extends BaseController {

    public function search()
    {
        $category = Input::get('category', 'default category');
        $term = Input::get('term', false);

        // do things with them...
    }
}

Usefully, you can set defaults in Input::get() in case nothing is passed to your Controller's action.

As joe_archer says, it's not necessary to put these terms into the URL, and it might be better as a POST (in which case you should update your call to Form::open() and also your search route in routes.php - Input::get() remains the same)

Try this

Sub Sample()
    Dim test As Worksheet
    Sheets(1).Copy After:=Sheets(Sheets.Count)
    Set test = ActiveSheet
    test.Name = "copied sheet!"
End Sub

For a structure definition that is to be used across more than one source file, you should definitely put it in a header file. Then include that header file in any source file that needs the structure.

The extern declaration is not used for structure definitions, but is instead used for variable declarations (that is, some data value with a structure type that you have defined). If you want to use the same variable across more than one source file, declare it as extern in a header file like:

extern struct a myAValue;

Then, in one source file, define the actual variable:

struct a myAValue;

If you forget to do this or accidentally define it in two source files, the linker will let you know about this.

Not with primitive arrays. You'll need to use a List or some other data structure:

List<Integer> items = Collections.unmodifiableList(Arrays.asList(0,1,2,3));

The sequel gem adds an update_or_create method which seems to do what you're looking for.

Have you used the variable sum anywhere else? That would explain it.

>>> sum = 1
>>> numbers = [1, 2, 3]
>>> numsum = (sum(numbers))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'int' object is not callable

The name sum doesn't point to the function anymore now, it points to an integer.

Solution: Don't call your variable sum, call it total or something similar.

The following event listener solved this nicely for me even when using multiple markers and info windows:

//Add click event listener
google.maps.event.addListener(marker, 'click', function() {
  // Helper to check if the info window is already open
  google.maps.InfoWindow.prototype.isOpen = function(){
      var map = infoWindow.getMap();
      return (map !== null && typeof map !== "undefined");
  }
  // Do the check
  if (infoWindow.isOpen()){
    // Close the info window
    infoWindow.close();
  } else {
    //Set the new content
    infoWindow.setContent(contentString);
    //Open the infowindow
    infoWindow.open(map, marker);
  }
});

Sample code block for strong password:

(?=.*[0-9])(?=.*[a-z])(?=.*[A-Z])(?=.*[^a-zA-Z0-9])(?=\\S+$).{6,18}

1. at least 6 digits
2. up to 18 digits
3. one number
4. one lowercase
5. one uppercase
6. can contain all special characters

For remove in NestJS need to add option to Shema() decorator

Read SVNBook | Client Credentials.

With modern SVN you can just run svn auth to display the list of cached credentials. Don't forget to make sure that you run up-to-date SVN client version because svn auth was introduced in version 1.9. The last line will specify the path to credential store which by default is %APPDATA%\Subversion\auth on Windows and ~/.subversion/auth/ on Unix-like systems.

PS C:\Users\MyUser> svn auth
------------------------------------------------------------------------
Credential kind: svn.simple
Authentication realm: <https://svn.example.local:443> VisualSVN Server
Password cache: wincrypt
Password: [not shown]

Credentials cache in 'C:\Users\MyUser\AppData\Roaming\Subversion' contains 5 credentials

You should use this:

<Link to={this.props.myroute} onClick={hello}>Here</Link>

Or (if method hello lays at this class):

<Link to={this.props.myroute} onClick={this.hello}>Here</Link>

Update: For ES6 and latest if you want to bind some param with click method, you can use this:

    const someValue = 'some';  
....  
    <Link to={this.props.myroute} onClick={() => hello(someValue)}>Here</Link>

There is a simplified solution from bootstrap here (where you don't need to create a new class): http://getbootstrap.com/examples/sticky-footer-navbar/

When you open that page, right click on a browser and "View Source" and open the sticky-footer-navbar.css file (http://getbootstrap.com/examples/sticky-footer-navbar/sticky-footer-navbar.css)

you can see that you only need this CSS

/* Sticky footer styles
-------------------------------------------------- */
html {
  position: relative;
  min-height: 100%;
}
body {
  /* Margin bottom by footer height */
  margin-bottom: 60px;
}
.footer {
  position: absolute;
  bottom: 0;
  width: 100%;
  /* Set the fixed height of the footer here */
  height: 60px;
  background-color: #f5f5f5;
}

for this HTML

<html>
    ...
    <body>
        <!-- Begin page content -->
        <div class="container">
        </div>
        ...

        <footer class="footer">
        </footer>
    </body>
</html>

Two problems- List is empty. You need to add some buttons to the list first. Second problem: You can't add buttons to "this". "This" is not referencing what you think, I think. Change this to reference a Panel for instance.

//Assume you have on your .aspx page:
<asp:Panel ID="Panel_Controls" runat="server"></asp:Panel>


private void button1_Click(object sender, EventArgs e)
    {
        List<Button> buttons = new List<Button>();


        for (int i = 0; i < buttons.Capacity; i++)
        {
            Panel_Controls.Controls.Add(buttons[i]);   
        }
    }

Spring MVC will give you the HttpRequest if you just add it to your controller method signature:

For instance:

/**
 * Generate a PDF report...
 */
@RequestMapping(value = "/report/{objectId}", method = RequestMethod.GET)
public @ResponseBody void generateReport(
        @PathVariable("objectId") Long objectId, 
        HttpServletRequest request, 
        HttpServletResponse response) {

    // ...
    // Here you can use the request and response objects like:
    // response.setContentType("application/pdf");
    // response.getOutputStream().write(...);

}

As you see, simply adding the HttpServletRequest and HttpServletResponse objects to the signature makes Spring MVC to pass those objects to your controller method. You'll want the HttpSession object too.

EDIT: It seems that HttpServletRequest/Response are not working for some people under Spring 3. Try using Spring WebRequest/WebResponse objects as Eduardo Zola pointed out.

I strongly recommend you to have a look at the list of supported arguments that Spring MVC is able to auto-magically inject to your handler methods.

Check it's value property:

In jQuery (since your tag mentions it):

$('#fileInput').val()

Or in vanilla JavaScript:

document.getElementById('myFileInput').value

At some point, I suppose you will add your programatically created LinearLayout to some root layout that you defined in .xml. This is just a suggestion of mine and probably one of many solutions, but it works: Simply set an ID for the programatically created layout, and add it to the root layout that you defined in .xml, and then use the set ID to add the Fragment.

It could look like this:

LinearLayout rowLayout = new LinearLayout();
rowLayout.setId(whateveryouwantasid);
// add rowLayout to the root layout somewhere here

FragmentManager fragMan = getFragmentManager();
FragmentTransaction fragTransaction = fragMan.beginTransaction();   

Fragment myFrag = new ImageFragment();
fragTransaction.add(rowLayout.getId(), myFrag , "fragment" + fragCount);
fragTransaction.commit();

Simply choose whatever Integer value you want for the ID:

rowLayout.setId(12345);

If you are using the above line of code not just once, it would probably be smart to figure out a way to create unique-IDs, in order to avoid duplicates.

UPDATE:

Here is the full code of how it should be done: (this code is tested and works) I am adding two Fragments to a LinearLayout with horizontal orientation, resulting in the Fragments being aligned next to each other. Please also be aware, that I used a fixed height and width of 200dp, so that one Fragment does not use the full screen as it would with "match_parent".

MainActivity.java:

public class MainActivity extends Activity {

    @SuppressLint("NewApi")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);     

        LinearLayout fragContainer = (LinearLayout) findViewById(R.id.llFragmentContainer);

        LinearLayout ll = new LinearLayout(this);
        ll.setOrientation(LinearLayout.HORIZONTAL);

        ll.setId(12345);

        getFragmentManager().beginTransaction().add(ll.getId(), TestFragment.newInstance("I am frag 1"), "someTag1").commit();
        getFragmentManager().beginTransaction().add(ll.getId(), TestFragment.newInstance("I am frag 2"), "someTag2").commit();

        fragContainer.addView(ll);
    }
}

TestFragment.java:

public class TestFragment extends Fragment {

    public static TestFragment newInstance(String text) {

        TestFragment f = new TestFragment();

        Bundle b = new Bundle();
        b.putString("text", text);
        f.setArguments(b);
        return f;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View v =  inflater.inflate(R.layout.fragment, container, false);

        ((TextView) v.findViewById(R.id.tvFragText)).setText(getArguments().getString("text"));     
        return v;
    }
}

activity_main.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/rlMain"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="5dp"
    tools:context=".MainActivity" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

    <LinearLayout
        android:id="@+id/llFragmentContainer"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignLeft="@+id/textView1"
        android:layout_below="@+id/textView1"
        android:layout_marginTop="19dp"
        android:orientation="vertical" >
    </LinearLayout>
</RelativeLayout>

fragment.xml:

  <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="200dp"
    android:layout_height="200dp" >

    <TextView
        android:id="@+id/tvFragText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:text="" />

</RelativeLayout>

And this is the result of the above code: (the two Fragments are aligned next to each other)

A parameter is the variable which is part of the method’s signature (method declaration). An argument is an expression used when calling the method.

Consider the following code:

void Foo(int i, float f)
{
    // Do things
}

void Bar()
{
    int anInt = 1;
    Foo(anInt, 2.0);
}

Here i and f are the parameters, and anInt and 2.0 are the arguments.

The solution above won't work if the original string has no spaces.

Try this:

var title = "This is your title";
var shortText = jQuery.trim(title).substring(0, 10)
                          .trim(this) + "...";

You can add and remove classes with jQuery like so:

$(".first").addClass("second")
// remove a class
$(".first").removeClass("second")

By the way you can set multiple classes in your markup right away separated with a whitespace

<div class="second first"></div>

    function calculatePercentage($oldFigure, $newFigure)
{
    $percentChange = (($oldFigure - $newFigure) / $oldFigure) * 100;
    return round(abs($percentChange));
}

Use on :

$('#registered_participants').on('click', '.new_participant_form', function() {

So that the click is delegated to any element in #registered_participants having the class new_participant_form, even if it's added after you bound the event handler.

By default, Elasticsearch installed goes into read-only mode when you have less than 5% of free disk space. If you see errors similar to this:

Elasticsearch::Transport::Transport::Errors::Forbidden: [403] {"error":{"root_cause":[{"type":"cluster_block_exception","reason":"blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"}],"type":"cluster_block_exception","reason":"blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"},"status":403}

Or in /usr/local/var/log/elasticsearch.log you can see logs similar to:

flood stage disk watermark [95%] exceeded on [nCxquc7PTxKvs6hLkfonvg][nCxquc7][/usr/local/var/lib/elasticsearch/nodes/0] free: 15.3gb[4.1%], all indices on this node will be marked read-only

Then you can fix it by running the following commands:

curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_cluster/settings -d '{ "transient": { "cluster.routing.allocation.disk.threshold_enabled": false } }'
curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'

u[8] = (u[8] | 0x80) & 0xBF // what's the purpose ?
u[6] = (u[6] | 0x40) & 0x4F // what's the purpose ?

These lines clamp the values of byte 6 and 8 to a specific range. rand.Read returns random bytes in the range 0-255, which are not all valid values for a UUID. As far as I can tell, this should be done for all the values in the slice though.

If you are on linux, you can alternatively call /usr/bin/uuidgen.

package main

import (
    "fmt"
    "log"
    "os/exec"
)

func main() {
    out, err := exec.Command("uuidgen").Output()
    if err != nil {
        log.Fatal(err)
    }
    fmt.Printf("%s", out)
}

Which yields:

$ go run uuid.go 
dc9076e9-2fda-4019-bd2c-900a8284b9c4

Without the use of any other library you can look at the BMP file format. I've implemented it in the past and it can be done without too much work.

Bitmap-File Structures

Each bitmap file contains a bitmap-file header, a bitmap-information header, a color table, and an array of bytes that defines the bitmap bits. The file has the following form:

BITMAPFILEHEADER bmfh;
BITMAPINFOHEADER bmih;
RGBQUAD aColors[];

I've written shyaml in python for YAML query needs from the shell command line.

Overview:

$ pip install shyaml      ## installation

Example's YAML file (with complex features):

$ cat <<EOF > test.yaml
name: "MyName !!"
subvalue:
    how-much: 1.1
    things:
        - first
        - second
        - third
    other-things: [a, b, c]
    maintainer: "Valentin Lab"
    description: |
        Multiline description:
        Line 1
        Line 2
EOF

Basic query:

$ cat test.yaml | shyaml get-value subvalue.maintainer
Valentin Lab

More complex looping query on complex values:

$ cat test.yaml | shyaml values-0 | \
  while read -r -d $'\0' value; do
      echo "RECEIVED: '$value'"
  done
RECEIVED: '1.1'
RECEIVED: '- first
- second
- third'
RECEIVED: '2'
RECEIVED: 'Valentin Lab'
RECEIVED: 'Multiline description:
Line 1
Line 2'

A few key points:

• all YAML types and syntax oddities are correctly handled, as multiline, quoted strings, inline sequences...
• \0 padded output is available for solid multiline entry manipulation.
• simple dotted notation to select sub-values (ie: subvalue.maintainer is a valid key).
• access by index is provided to sequences (ie: subvalue.things.-1 is the last element of the subvalue.things sequence.)
• access to all sequence/structs elements in one go for use in bash loops.
• you can output whole subpart of a YAML file as ... YAML, which blend well for further manipulations with shyaml.

More sample and documentation are available on the shyaml github page or the shyaml PyPI page.

Look at the Java documentation for the Thread class. You can check the thread's state. If you put the three threads in member variables, then all three threads can read each other's states.

You have to be a bit careful, though, because you can cause race conditions between the threads. Just try to avoid complicated logic based on the state of the other threads. Definitely avoid multiple threads writing to the same variables.

There's Salamander, which is a native .NET compiler and linker from Remotesoft that can deploy applications without the .NET framework. I don't know how well it lives up to its claims.

You can use preg_replace in this case;

$res = preg_replace("/[^0-9]/", "", "Every 6 Months" );

$res return 6 in this case.

If want also to include decimal separator or thousand separator check this example:

$res = preg_replace("/[^0-9.]/", "", "$ 123.099");

$res returns "123.099" in this case

Include period as decimal separator or thousand separator: "/[^0-9.]/"

Include coma as decimal separator or thousand separator: "/[^0-9,]/"

Include period and coma as decimal separator and thousand separator: "/[^0-9,.]/"

Remove the semicolon ( ; ).

In oracle, you can use semicolon or not when u ran query directly on DB. But when u using java to ran a oracle query, u have to remove semicolon at the end.

I think this is very nice and short

<img src="imagenotfound.gif" alt="Image not found" onerror="this.src='imagefound.gif';" />

But, be careful. The user's browser will be stuck in an endless loop if the onerror image itself generates an error.

EDIT To avoid endless loop, remove the onerror from it at once.

<img src="imagenotfound.gif" alt="Image not found" onerror="this.onerror=null;this.src='imagefound.gif';" />

By calling this.onerror=null it will remove the onerror then try to get the alternate image.

NEW I would like to add a jQuery way, if this can help anyone.

<script>
$(document).ready(function()
{
    $(".backup_picture").on("error", function(){
        $(this).attr('src', './images/nopicture.png');
    });
});
</script>

<img class='backup_picture' src='./images/nonexistent_image_file.png' />

You simply need to add class='backup_picture' to any img tag that you want a backup picture to load if it tries to show a bad image.

Some time when we use Environ() function we may get the Library or property not found error. Use VBA.Environ() or VBA.Environ$() to avoid the error.

What I do in my scripts is check at runtime if the 'verbose' option is set, and then set my logging level to debug. If it's not set, I set it to info. This way you don't have 'if verbose' checks all over your code.

If you are not averse to boost, boost.tokenizer is flexible enough to solve this

#include <string>
#include <iostream>
#include <boost/tokenizer.hpp>

void split_and_show(const std::string s)
{
    boost::char_separator<char> sep(" ", "", boost::keep_empty_tokens);
    boost::tokenizer<boost::char_separator<char> > tok(s, sep);
    for(auto i = tok.begin(); i!=tok.end(); ++i)
            std::cout << '"' << *i << "\"\n";
}
int main()
{
    split_and_show("This is a string");
    split_and_show("This  is a string");

}

Yes using Option Explicit is a good habit. Using .Select however is not :) it reduces the speed of the code. Also fully justify sheet names else the code will always run for the Activesheet which might not be what you actually wanted.

Is this what you are trying?

Option Explicit

Sub Sample()
    Dim lastRow As Long, i As Long
    Dim CopyRange As Range

    '~~> Change Sheet1 to relevant sheet name
    With Sheets("Sheet1")
        lastRow = .Range("A" & .Rows.Count).End(xlUp).Row

        For i = 2 To lastRow
            If Len(Trim(.Range("A" & i).Value)) <> 0 Then
                If CopyRange Is Nothing Then
                    Set CopyRange = .Rows(i)
                Else
                    Set CopyRange = Union(CopyRange, .Rows(i))
                End If
            Else
                Exit For
            End If
        Next

        If Not CopyRange Is Nothing Then
            '~~> Change Sheet2 to relevant sheet name
            CopyRange.Copy Sheets("Sheet2").Rows(1)
        End If
    End With
End Sub

NOTE

If if you have data from Row 2 till Row 10 and row 11 is blank and then you have data again from Row 12 then the above code will only copy data from Row 2 till Row 10

If you want to copy all rows which have data then use this code.

Option Explicit

Sub Sample()
    Dim lastRow As Long, i As Long
    Dim CopyRange As Range

    '~~> Change Sheet1 to relevant sheet name
    With Sheets("Sheet1")
        lastRow = .Range("A" & .Rows.Count).End(xlUp).Row

        For i = 2 To lastRow
            If Len(Trim(.Range("A" & i).Value)) <> 0 Then
                If CopyRange Is Nothing Then
                    Set CopyRange = .Rows(i)
                Else
                    Set CopyRange = Union(CopyRange, .Rows(i))
                End If
            End If
        Next

        If Not CopyRange Is Nothing Then
            '~~> Change Sheet2 to relevant sheet name
            CopyRange.Copy Sheets("Sheet2").Rows(1)
        End If
    End With
End Sub

Hope this is what you wanted?

I don't know if this is happening to you, but sometimes I choose the wrong directory to merge and I get this error even though all the files appear completely fine.

Example:

Merge /svn/Project/branches/some-branch/Sources to /svn/Project/trunk ---> Tree conflict

Merge /svn/Project/branches/some-branch to /svn/Project/trunk ---> OK

This might be a stupid mistake, but it's not always obvious because you think it's something more complicated.

List is an ordered sequence of elements whereas Set is a distinct list of elements which is unordered (thank you, Quinn Taylor).

List<E>:

An ordered collection (also known as a sequence). The user of this interface has precise control over where in the list each element is inserted. The user can access elements by their integer index (position in the list), and search for elements in the list.

Set<E>:

A collection that contains no duplicate elements. More formally, sets contain no pair of elements e1 and e2 such that e1.equals(e2), and at most one null element. As implied by its name, this interface models the mathematical set abstraction.

You should definitely have a look at this answer of mine:

• Extracting table contents from a collection of PDF files

and also have a look at all the links included therein.

Tabula/TabulaPDF is currently the best table extraction tool that is available for PDF scraping.

states.split() will return

['Alaska',
 'Alabama',
 'Arkansas',
 'American',
 'Samoa',
 'Arizona',
 'California',
 'Colorado']

If you need one random from them, then you have to use the random module:

import random

states = "... ..."

random_state = random.choice(states.split())

The "coef" option of the geom_boxplot function allows to change the outlier cutoff in terms of interquartile ranges. This option is documented for the function stat_boxplot. To deactivate outliers (in other words they are treated as regular data), one can instead of using the default value of 1.5 specify a very high cutoff value:

library(ggplot2)
# generate data with outliers:
df = data.frame(x=1, y = c(-10, rnorm(100), 10)) 
# generate plot with increased cutoff for outliers:
ggplot(df, aes(x, y)) + geom_boxplot(coef=1e30)

It sounds like something like the below will suit your needs:

With Sheets("Sheet1")
    .Rows( X & ":" & .Rows.Count).Delete
End With

Where X is a variable that = the row number ( 415 )

The following shell script will iterate through all users and print only those user names which belong to a given group:

#!/usr/bin/env bash
getent passwd | while IFS=: read name trash
do
    groups $name 2>/dev/null | cut -f2 -d: | grep -i -q -w "$1" && echo $name
done
true

Usage example:

./script 'DOMAIN+Group Name'

Note: This solution will check NIS and LDAP for users and groups (not only passwd and group files). It will also take into account users not added to a group but having group set as primary group.

Edit: Added fix for rare scenario where user does not belong to group with the same name.

Edit: written in the form of a shell script; added true to exit with 0 status as suggested by @Max Chernyak aka hakunin; discarded stderr in order to skip those occasional groups: cannot find name for group ID xxxxxx.

I think this will work perfectly. I used the same:

For Android Studio:

1. Click on Build > Generate Signed APK.
2. You will get a message box, just click OK.
3. Now there will be another window just copy Key Store Path.
4. Now open a command prompt and go to C:\Program Files\Java\jdk1.6.0_39\bin> (or any installed jdk version).
5. Type keytool -list -v -keystore and then paste your Key Store Path (Eg. C:\Program Files\Java\jdk1.6.0_39\bin>keytool -list -v -keystore "E:\My Projects \Android\android studio\signed apks\Hello World\HelloWorld.jks").
6. Now it will Ask Key Store Password, provide yours and press Enter to get your SHA1 and MD5 Certificate keys.

A little modification to typescript:

  public encodeData(data: any): string {
    return Object.keys(data).map((key) => {
      return [key, data[key]].map(encodeURIComponent).join("=");
    }).join("&");
  }

Here is a function that compares your test data against the training data, with the Tf-Idf transformer fitted with the training data. Advantage is that you can quickly pivot or group by to find the n closest elements, and that the calculations are down matrix-wise.

def create_tokenizer_score(new_series, train_series, tokenizer):
    """
    return the tf idf score of each possible pairs of documents
    Args:
        new_series (pd.Series): new data (To compare against train data)
        train_series (pd.Series): train data (To fit the tf-idf transformer)
    Returns:
        pd.DataFrame
    """

    train_tfidf = tokenizer.fit_transform(train_series)
    new_tfidf = tokenizer.transform(new_series)
    X = pd.DataFrame(cosine_similarity(new_tfidf, train_tfidf), columns=train_series.index)
    X['ix_new'] = new_series.index
    score = pd.melt(
        X,
        id_vars='ix_new',
        var_name='ix_train',
        value_name='score'
    )
    return score

train_set = pd.Series(["The sky is blue.", "The sun is bright."])
test_set = pd.Series(["The sun in the sky is bright."])
tokenizer = TfidfVectorizer() # initiate here your own tokenizer (TfidfVectorizer, CountVectorizer, with stopwords...)
score = create_tokenizer_score(train_series=train_set, new_series=test_set, tokenizer=tokenizer)

The previous answers were accurate, but perhaps too terse. I will try to add some examples.

First of all, the word "proxy" describes someone or something acting on behalf of someone else.

In the computer realm, we are talking about one server acting on the behalf of another computer.

For the purposes of accessibility, I will limit my discussion to web proxies - however, the idea of a proxy is not limited to websites.

FORWARD proxy

Most discussion of web proxies refers to the type of proxy known as a "forward proxy."

The proxy event, in this case, is that the "forward proxy" retrieves data from another web site on behalf of the original requestee.

A tale of 3 computers (part I)

For an example, I will list three computers connected to the internet.

• X = your computer, or "client" computer on the internet
• Y = the proxy web site, proxy.example.org
• Z = the web site you want to visit, www.example.net

Normally, one would connect directly from X --> Z.

However, in some scenarios, it is better for Y --> Z on behalf of X, which chains as follows: X --> Y --> Z.

Reasons why X would want to use a forward proxy server:

Here is a (very) partial list of uses of a forward proxy server:

• 1) X is unable to access Z directly because

  • a) Someone with administrative authority over X's internet connection has decided to block all access to site Z.

    • Examples:

      • The Storm Worm virus is spreading by tricking people into visiting familypostcards2008.com, so the system administrator has blocked access to the site to prevent users from inadvertently infecting themselves.

      • Employees at a large company have been wasting too much time on facebook.com, so management wants access blocked during business hours.

      • A local elementary school disallows internet access to the playboy.com website.

      • A government is unable to control the publishing of news, so it controls access to news instead, by blocking sites such as wikipedia.org. See TOR or FreeNet.

  • b) The administrator of Z has blocked X.

    • Examples:

      • The administrator of Z has noticed hacking attempts coming from X, so the administrator has decided to block X's IP address (and/or netrange).

      • Z is a forum website. X is spamming the forum. Z blocks X.

REVERSE proxy

A tale of 3 computers (part II)

For this example, I will list three computers connected to the internet.

• X = your computer, or "client" computer on the internet
• Y = the reverse proxy web site, proxy.example.com
• Z = the web site you want to visit, www.example.net

Normally, one would connect directly from X --> Z.

However, in some scenarios, it is better for the administrator of Z to restrict or disallow direct access and force visitors to go through Y first. So, as before, we have data being retrieved by Y --> Z on behalf of X, which chains as follows: X --> Y --> Z.

What is different this time compared to a "forward proxy," is that this time the user X does not know he is accessing Z, because the user X only sees he is communicating with Y. The server Z is invisible to clients and only the reverse proxy Y is visible externally. A reverse proxy requires no (proxy) configuration on the client side.

The client X thinks he is only communicating with Y (X --> Y), but the reality is that Y forwarding all communication (X --> Y --> Z again).

Reasons why Z would want to set up a reverse proxy server:

• 1) Z wants to force all traffic to its web site to pass through Y first.
  • a) Z has a large web site that millions of people want to see, but a single web server cannot handle all the traffic. So Z sets up many servers and puts a reverse proxy on the internet that will send users to the server closest to them when they try to visit Z. This is part of how the Content Distribution Network (CDN) concept works.
    • Examples:
      • Apple Trailers uses Akamai
      • Jquery.com hosts its JavaScript files using CloudFront CDN (sample).
      • etc.
• 2) The administrator of Z is worried about retaliation for content hosted on the server and does not want to expose the main server directly to the public.
  • a) Owners of Spam brands such as "Canadian Pharmacy" appear to have thousands of servers, while in reality having most websites hosted on far fewer servers. Additionally, abuse complaints about the spam will only shut down the public servers, not the main server.

In the above scenarios, Z has the ability to choose Y.

If you happen to use LuaSocket in your project, or just have it installed and don't mind to use it, you can use the socket.sleep(time) function which sleeps for a given amount of time (in seconds).

This works both on Windows and Unix, and you do not have to compile additional modules.

I should add that the function supports fractional seconds as a parameter, i.e. socket.sleep(0.5) will sleep half a second. It uses Sleep() on Windows and nanosleep() elsewhere, so you may have issues with Windows accuracy when time gets too low.

Put this in your CSS:

white-space:nowrap;

Get more information here: http://www.w3.org/wiki/CSS/Properties/white-space

white-space

The white-space property declares how white space inside the element is handled.

Values

normal This value directs user agents to collapse sequences of white space, and break lines as necessary to fill line boxes.

pre This value prevents user agents from collapsing sequences of white space. Lines are only broken at newlines in the source, or at occurrences of "\A" in generated content.

nowrap This value collapses white space as for 'normal', but suppresses line breaks within text.

pre-wrap This value prevents user agents from collapsing sequences of white space. Lines are broken at newlines in the source, at occurrences of "\A" in generated content, and as necessary to fill line boxes.

pre-line This value directs user agents to collapse sequences of white space. Lines are broken at newlines in the source, at occurrences of "\A" in generated content, and as necessary to fill line boxes.

inherit Takes the same specified value as the property for the element's parent.

Even in base Python you can do the computation in generic form

result = sum(x**2 for x in some_vector) ** 0.5

x ** 2 is surely not an hack and the computation performed is the same (I checked with cpython source code). I actually find it more readable (and readability counts).

Using instead x ** 0.5 to take the square root doesn't do the exact same computations as math.sqrt as the former (probably) is computed using logarithms and the latter (probably) using the specific numeric instruction of the math processor.

I often use x ** 0.5 simply because I don't want to add math just for that. I'd expect however a specific instruction for the square root to work better (more accurately) than a multi-step operation with logarithms.

One of the most important steps is to sanitize any user input before it is processed and/or rendered back to the browser. PHP has some "filter" functions that can be used.

The form that XSS attacks usually have is to insert a link to some off-site javascript that contains malicious intent for the user. Read more about it here.

You'll also want to test your site - I can recommend the Firefox add-on XSS Me.

In my case, I had 2 forms in differents views and differents router files. The first router used the name field with view one and its file name was "inputGroupFile02". The second view had another name for file input. For some reason Multer not allows you set differents name in different views, so I dicided to use same name for the file input in both views.

What you wrote sends a list of newline separated file names (and paths) to rm, but rm doesn't know what to do with that input. It's only expecting command line parameters.

xargs takes input, usually separated by newlines, and places them on the command line, so adding xargs makes what you had work:

find . -name .svn | xargs rm -fr

xargs is intelligent enough that it will only pass as many arguments to rm as it can accept. Thus, if you had a million files, it might run rm 1,000,000/65,000 times (if your shell could accept 65,002 arguments on the command line {65k files + 1 for rm + 1 for -fr}).

As persons have adeptly pointed out, the following also work:

find . -name .svn -exec rm -rf {} \;
find . -depth -name .svn -exec rm -fr {} \;
find . -type d -name .svn -print0|xargs -0 rm -rf

The first two -exec forms both call rm for each folder being deleted, so if you had 1,000,000 folders, rm would be invoked 1,000,000 times. This is certainly less than ideal. Newer implementations of rm allow you to conclude the command with a + indicating that rm will accept as many arguments as possible:

find . -name .svn -exec rm -rf {} +

The last find/xargs version uses print0, which makes find generate output that uses \0 as a terminator rather than a newline. Since POSIX systems allow any character but \0 in the filename, this is truly the safest way to make sure that the arguments are correctly passed to rm or the application being executed.

In addition, there's a -execdir that will execute rm from the directory in which the file was found, rather than at the base directory and a -depth that will start depth first.

Otherwise we may change the default property configurator name, setting the property spring.config.name=test and then having class-path resource src/test/test.properties our native instance of org.springframework.boot.SpringApplication will be auto-configured from this separated test.properties, ignoring application properties;

Benefit: auto-configuration of tests;

Drawback: exposing "spring.config.name" property at C.I. layer

If you're using AVD manager add a hardware property Keyboard support and set it to false.

That should disable the shown keyboard, and show the virtual one.

File > Invalidate Caches/Restart... 

For conversion,you can create ~/.my.cnf file in host:

[Mysql]
user=root
password=yourpass
host=127.0.0.1
port=3306

Then next time just run mysql for mysql client to open connection.

I would start by reading up on streams on MSDN: http://msdn.microsoft.com/en-us/library/system.io.stream.aspx

Memorystream and FileStream are streams used to work with raw memory and Files respectively...

The equivalence would be

for i in (0...array.size)
end

or

(0...array.size).each do |i|
end

or

i = 0
while i < array.size do
   array[i]
   i = i + 1 # where you may freely set i to any value
end

iCalendar was based on a vCalendar and Outlook 2007 handles both formats well so it doesn't really matters which one you choose.

I'm not sure if this stands for Outlook 2003. I guess you should give it a try.

Outlook's default calendar format is iCalendar (*.ics)

A covering index is one which can satisfy all requested columns in a query without performing a further lookup into the clustered index.

There is no such thing as a covering query.

Have a look at this Simple-Talk article: Using Covering Indexes to Improve Query Performance.

Here's an example of how to validate a int and a String that you pass from the Java Controller to the JSP file.

MainController.java:

@RequestMapping(value="/ImportJavaToJSP")
public ModelAndView getImportJavaToJSP() {
    ModelAndView model2= new ModelAndView("importJavaToJSPExamples");

    int someNumberValue=6;
    String someStringValue="abcdefg";
    //model2.addObject("someNumber", someNumberValue);
    model2.addObject("someString", someStringValue);

    return model2;
}

importJavaToJSPExamples.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<p>${someNumber}</p>
<c:if test="${not empty someNumber}">
    <p>someNumber is Not Empty</p>
</c:if>
<c:if test="${empty someNumber}">
    <p>someNumber is Empty</p>
</c:if>
<p>${someString}</p>
<c:if test="${not empty someString}">
    <p>someString is Not Empty</p>
</c:if>
<c:if test="${empty someString}">
    <p>someString is Empty</p>
</c:if>

Another answer, hopefully simpler. (for fellow googlers)

Suppose you have Team and Member objects.

Obviously it's a relationship : the Team object will have pointers to its Members. And it's likely that the members will also have a back pointer to their Team object.

Then you have a dependency cycle. If you use shared_ptr, objects will no longer be automatically freed when you abandon reference on them, because they reference each other in a cyclic way. This is a memory leak.

You break this by using weak_ptr. The "owner" typically use shared_ptr and the "owned" use a weak_ptr to its parent, and convert it temporarily to shared_ptr when it needs access to its parent.

Store a weak ptr :

weak_ptr<Parent> parentWeakPtr_ = parentSharedPtr; // automatic conversion to weak from shared

then use it when needed

shared_ptr<Parent> tempParentSharedPtr = parentWeakPtr_.lock(); // on the stack, from the weak ptr
if( !tempParentSharedPtr ) {
  // yes, it may fail if the parent was freed since we stored weak_ptr
} else {
  // do stuff
}
// tempParentSharedPtr is released when it goes out of scope

Starting from Angular version 9:

Breaking changes:

Components can no longer be imported through "@angular/material". Use the individual secondary entry-points, such as @angular/material/button.

This means that:

import { MatInputModule, MatCardModule } from "@angular/material";

becomes:

import { MatInputModule } from "@angular/material/input";
import { MatCardModule } from "@angular/material/card";

This one is easy. When you start the installation, Anaconda asks "Destination Folder" as below screenshot. If you are not sure where did default installation go, double click setup file and see what anaconda offers as a default location.

I noticed that you commented in 2011 but i thought i should post this answer anyway, in case anyone needs to "replace the original string" and runs into this answer ..

Im using a EditText as an example

// GIVE TARGET TEXT BOX A NAME

 EditText textbox = (EditText) findViewById(R.id.your_textboxID);

// STRING TO REPLACE

 String oldText = "hello"
 String newText = "Hi";      
 String textBoxText = textbox.getText().toString();

// REPLACE STRINGS WITH RETURNED STRINGS

String returnedString = textBoxText.replace( oldText, newText );

// USE RETURNED STRINGS TO REPLACE NEW STRING INSIDE TEXTBOX

textbox.setText(returnedString);

This is untested, but it's just an example of using the returned string to replace the original layouts string with setText() !

Obviously this example requires that you have a EditText with the ID set to your_textboxID

This can get really cool with an extension (functioning as a proxy), for example:

collection.SelectWithIndex(); 
// vs. 
collection.Select((item, index) => item);

Which will automagically assign indexes to the collection accessible via this Index property.

Interface:

public interface IIndexable
{
    int Index { get; set; }
}

Custom extension (probably most useful for working with EF and DbContext):

public static class EnumerableXtensions
{
    public static IEnumerable<TModel> SelectWithIndex<TModel>(
        this IEnumerable<TModel> collection) where TModel : class, IIndexable
    {
        return collection.Select((item, index) =>
        {
            item.Index = index;
            return item;
        });
    }
}

public class SomeModelDTO : IIndexable
{
    public Guid Id { get; set; }
    public string Name { get; set; }
    public decimal Price { get; set; }

    public int Index { get; set; }
}

// In a method
var items = from a in db.SomeTable
            where a.Id == someValue
            select new SomeModelDTO
            {
                Id = a.Id,
                Name = a.Name,
                Price = a.Price
            };

return items.SelectWithIndex()
            .OrderBy(m => m.Name)
            .Skip(pageStart)
            .Take(pageSize)
            .ToList();

This usually means that you have "incompatibilities with the current version of MySQL Server", see mysql_upgrade. I ran into this same issue and simply had to run:

mysql_upgrade --password The documentation states that, "mysql_upgrade should be executed each time you upgrade MySQL".

All Possible Word with stack

from itertools import permutations
for i in permutations('stack'):
    print(''.join(i))

permutations(iterable, r=None)

Return successive r length permutations of elements in the iterable.

If r is not specified or is None, then r defaults to the length of the iterable and all possible full-length permutations are generated.

Permutations are emitted in lexicographic sort order. So, if the input iterable is sorted, the permutation tuples will be produced in sorted order.

Elements are treated as unique based on their position, not on their value. So if the input elements are unique, there will be no repeat values in each permutation.

This Jquery method returns the default vale 0 when page loads...

$('input[type="radio"]:checked').val();

Hello you can make use of input and output. Input let you to pass variable form parent to child. Output the same but from child to parent.

The easiest way is to pass "startdate" and "endDate" as input

<calendar [startDateInCalendar]="startDateInSearch" [endDateInCalendar]="endDateInSearch" ></calendar>

In this way you have your startdate and enddate directly in search page. Let me know if it works, or think another way. Thanks

if you have a list a and then following statements

list<int>::iterator it; // declare an iterator
    list<int>::const_iterator cit; // declare an const iterator 
    it=a.begin();
    cit=a.begin();

you can change the contents of the element in the list using “it” but not “cit”, that is you can use “cit” for reading the contents not for updating the elements.

*it=*it+1;//returns no error
    *cit=*cit+1;//this will return error

Statsmodels kan build an OLS model with column references directly to a pandas dataframe.

Short and sweet:

model = sm.OLS(df[y], df[x]).fit()

Code details and regression summary:

# imports
import pandas as pd
import statsmodels.api as sm
import numpy as np

# data
np.random.seed(123)
df = pd.DataFrame(np.random.randint(0,100,size=(100, 3)), columns=list('ABC'))

# assign dependent and independent / explanatory variables
variables = list(df.columns)
y = 'A'
x = [var for var in variables if var not in y ]

# Ordinary least squares regression
model_Simple = sm.OLS(df[y], df[x]).fit()

# Add a constant term like so:
model = sm.OLS(df[y], sm.add_constant(df[x])).fit()

model.summary()

Output:

I tried lots of ways, and found that using datepicker was the best, but the date format causes problems with JavaScript....

So here's my answer and can be run out of the box.

<input type="text" id="startdate">
<input type="text" id="enddate">
<input type="text" id="days">

<script src="https://code.jquery.com/jquery-1.8.3.js"></script>
<script src="https://code.jquery.com/ui/1.10.0/jquery-ui.js"></script>
<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/redmond/jquery-ui.css" />
<script>
$(document).ready(function() {

$( "#startdate,#enddate" ).datepicker({
changeMonth: true,
changeYear: true,
firstDay: 1,
dateFormat: 'dd/mm/yy',
})

$( "#startdate" ).datepicker({ dateFormat: 'dd-mm-yy' });
$( "#enddate" ).datepicker({ dateFormat: 'dd-mm-yy' });

$('#enddate').change(function() {
var start = $('#startdate').datepicker('getDate');
var end   = $('#enddate').datepicker('getDate');

if (start<end) {
var days   = (end - start)/1000/60/60/24;
$('#days').val(days);
}
else {
alert ("You cant come back before you have been!");
$('#startdate').val("");
$('#enddate').val("");
$('#days').val("");
}
}); //end change function
}); //end ready
</script>

I would also like to mention a new functionality of AngularJS ng-repeat, namely, special repeat start and end points. That functionality was added in order to repeat a series of HTML elements instead of just a single parent HTML element.

In order to use repeater start and end points you have to define them by using ng-repeat-start and ng-repeat-end directives respectively.

The ng-repeat-start directive works very similar to ng-repeat directive. The difference is that is will repeat all the HTML elements (including the tag it's defined on) up to the ending HTML tag where ng-repeat-end is placed (including the tag with ng-repeat-end).

Sample code (from a controller):

// ...
$scope.users = {};
$scope.users["182982"] = {name:"John", age: 30};
$scope.users["198784"] = {name:"Antonio", age: 32};
$scope.users["119827"] = {name:"Stephan", age: 18};
// ...

Sample HTML template:

<div ng-repeat-start="(id, user) in users">
    ==== User details ====
</div>
<div>
    <span>{{$index+1}}. </span>
    <strong>{{id}} </strong>
    <span class="name">{{user.name}} </span>
    <span class="age">({{user.age}})</span>
</div>

<div ng-if="!$first">
   <img src="/some_image.jpg" alt="some img" title="some img" />
</div>
<div ng-repeat-end>
    ======================
</div>

Output would look similar to the following (depending on HTML styling):

==== User details ====
1.  119827 Stephan (18)
======================
==== User details ====
2.  182982 John (30)
[sample image goes here]
======================
==== User details ====
3.  198784 Antonio (32)
[sample image goes here]
======================

As you can see, ng-repeat-start repeats all HTML elements (including the element with ng-repeat-start). All ng-repeat special properties (in this case $first and $index) also work as expected.

Just because I made this mistake every time when using the submit function.

This is the full code you need:

Add the id "yourid" to the HTML form tag.

<form id="yourid" action='XXX' name='form' method='POST' accept-charset='UTF-8' enctype='multipart/form-data'>

the jQuery code:

$('#yourid').submit(function() {
  // do something
});

for (int j=0; j<test.length; j++) {
   System.out.format("%02X ", test[j]);
}
System.out.println();

If this is your first push

just change the

git push <repo name> master

change it like this!

git push -f <repo name> master

In some situations, it could be desirable to ensure the Unique key does not exists before create it. In such cases, the script below might help:

IF Exists(SELECT * FROM sys.indexes WHERE name Like '<index_name>')
    ALTER TABLE dbo.<target_table_name> DROP CONSTRAINT <index_name> 
GO

ALTER TABLE dbo.<target_table_name> ADD CONSTRAINT <index_name> UNIQUE NONCLUSTERED (<col_1>, <col_2>, ..., <col_n>) 
GO

The scope of local variables should always be the smallest possible.

In your example I presume str is not used outside of the while loop, otherwise you would not be asking the question, because declaring it inside the while loop would not be an option, since it would not compile.

So, since str is not used outside the loop, the smallest possible scope for str is within the while loop.

So, the answer is emphatically that str absolutely ought to be declared within the while loop. No ifs, no ands, no buts.

The only case where this rule might be violated is if for some reason it is of vital importance that every clock cycle must be squeezed out of the code, in which case you might want to consider instantiating something in an outer scope and reusing it instead of re-instantiating it on every iteration of an inner scope. However, this does not apply to your example, due to the immutability of strings in java: a new instance of str will always be created in the beginning of your loop and it will have to be thrown away at the end of it, so there is no possibility to optimize there.

EDIT: (injecting my comment below in the answer)

In any case, the right way to do things is to write all your code properly, establish a performance requirement for your product, measure your final product against this requirement, and if it does not satisfy it, then go optimize things. And what usually ends up happening is that you find ways to provide some nice and formal algorithmic optimizations in just a couple of places which make our program meet its performance requirements instead of having to go all over your entire code base and tweak and hack things in order to squeeze clock cycles here and there.

Mine Solution was just to add below style. <div class="modal-body" style="clear: both;overflow: hidden;">

If you are using windows, then take a look at this link. Otherwise, you may look for your OS specific version api. I don't think C++ comes with a cross-platform way to do it. At the end, it's NOT C++'s work, it's the OS's work.
