Remember you can access good old ECMAScript APIs, in this case, JSON.stringify().

For simple arrays like the one in your example:

require('fs').writeFile(

    './my.json',

    JSON.stringify(myArray),

    function (err) {
        if (err) {
            console.error('Crap happens');
        }
    }
);

It's difficult to tell what you're actually trying to do and if this is what you really need but you might also use a callback:

function myFunction(value1,callback)
{
     //Do stuff and 

     if(typeof callback == 'function'){
        callback(somevalue2,somevalue3);
    }
}


myFunction("1", function(value2, value3){
    if(value2 && value3)
    {
    //Do some stuff
    }
});

This answer on super user I think is a better answer. From https://superuser.com/a/573761/67952

"But since you asked for a way without using Before and After, you can use:

Type=idle

which as man systemd.service explains

Behavior of idle is very similar to simple; however, actual execution of the service program is delayed until all active jobs are dispatched. This may be used to avoid interleaving of output of shell services with the status output on the console. Note that this type is useful only to improve console output, it is not useful as a general unit ordering tool, and the effect of this service type is subject to a 5s time-out, after which the service program is invoked anyway. "

$(this).closest('form').find('input,textarea,select').not(':image').prop('disabled', true);

function extractSummary(iCalContent) {
  var rx = /\nSUMMARY:(.*)\n/g;
  var arr = rx.exec(iCalContent);
  return arr[1]; 
}

You need these changes:

• Put the * inside the parenthesis as suggested above. Otherwise your matching group will contain only one character.

• Get rid of the ^ and $. With the global option they match on start and end of the full string, rather than on start and end of lines. Match on explicit newlines instead.

• I suppose you want the matching group (what's inside the parenthesis) rather than the full array? arr[0] is the full match ("\nSUMMARY:...") and the next indexes contain the group matches.

• String.match(regexp) is supposed to return an array with the matches. In my browser it doesn't (Safari on Mac returns only the full match, not the groups), but Regexp.exec(string) works.

Docker now (version 1.13 or 17.06 and higher) has support for managing secret information. Here's an overview and more detailed documentation

Similar feature exists in kubernetes and DCOS

Show Notificaton in android 8.0

@TargetApi(Build.VERSION_CODES.O)
@RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN)

  public void show_Notification(){

    Intent intent=new Intent(getApplicationContext(),MainActivity.class);
    String CHANNEL_ID="MYCHANNEL";
    NotificationChannel notificationChannel=new NotificationChannel(CHANNEL_ID,"name",NotificationManager.IMPORTANCE_LOW);
    PendingIntent pendingIntent=PendingIntent.getActivity(getApplicationContext(),1,intent,0);
    Notification notification=new Notification.Builder(getApplicationContext(),CHANNEL_ID)
            .setContentText("Heading")
            .setContentTitle("subheading")
            .setContentIntent(pendingIntent)
            .addAction(android.R.drawable.sym_action_chat,"Title",pendingIntent)
            .setChannelId(CHANNEL_ID)
            .setSmallIcon(android.R.drawable.sym_action_chat)

    NotificationManager notificationManager=(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.createNotificationChannel(notificationChannel);
    notificationManager.notify(1,notification);


}

You can add the rules based on that selector using .rules("add", options), just remove any rules you want class based out of your validate options, and after calling $(".formToValidate").validate({... });, do this:

$(".checkBox").rules("add", { 
  required:true,  
  minlength:3
});

here is one that works:

UPDATE  `table_1`
INNER JOIN 
 `table_2` SET  col1= value, col2= val,col3= val,col4= val;

value is the column from table_2

I had a same problem and this fixed it:

You should add:

If you are like me who has tried all the above solutions and still your problem is not solved, I have a got a great solution for you that works like a charm. First I want clarify few things about some of solutions mentioned above.

1. In my case IQkeyboardmanager was working only when there is no auto layout applied on the elements, if it is applied then IQkeyboard manager will not work the way we think.
2. Same thing with upward movement of self.view.
3. i have wriiten a objective c header with a swift support for pushing UITexfield upward when user clicks on it, solving the problem of keyboard covering the UITextfield : https://github.com/coolvasanth/smart_keyboard.
4. One who has An intermediate or higher level in iOS app development can easily understand the repository and implement it. All the best

Below is a fully functional example of what I believe you're trying to do (with a functional snippet).

Explanation

Based on your question, you seem to be modifying 1 property in state for all of your elements. That's why when you click on one, all of them are being changed.

In particular, notice that the state tracks an index of which element is active. When MyClickable is clicked, it tells the Container its index, Container updates the state, and subsequently the isActive property of the appropriate MyClickables.

Example

class Container extends React.Component {_x000D_
  state = {_x000D_
    activeIndex: null_x000D_
  }_x000D_
_x000D_
  handleClick = (index) => this.setState({ activeIndex: index })_x000D_
_x000D_
  render() {_x000D_
    return <div>_x000D_
      <MyClickable name="a" index={0} isActive={ this.state.activeIndex===0 } onClick={ this.handleClick } />_x000D_
      <MyClickable name="b" index={1} isActive={ this.state.activeIndex===1 } onClick={ this.handleClick }/>_x000D_
      <MyClickable name="c" index={2} isActive={ this.state.activeIndex===2 } onClick={ this.handleClick }/>_x000D_
    </div>_x000D_
  }_x000D_
}_x000D_
_x000D_
class MyClickable extends React.Component {_x000D_
  handleClick = () => this.props.onClick(this.props.index)_x000D_
  _x000D_
  render() {_x000D_
    return <button_x000D_
      type='button'_x000D_
      className={_x000D_
        this.props.isActive ? 'active' : 'album'_x000D_
      }_x000D_
      onClick={ this.handleClick }_x000D_
    >_x000D_
      <span>{ this.props.name }</span>_x000D_
    </button>_x000D_
  }_x000D_
}_x000D_
_x000D_
ReactDOM.render(<Container />, document.getElementById('app'))

button {_x000D_
  display: block;_x000D_
  margin-bottom: 1em;_x000D_
}_x000D_
_x000D_
.album>span:after {_x000D_
  content: ' (an album)';_x000D_
}_x000D_
_x000D_
.active {_x000D_
  font-weight: bold;_x000D_
}_x000D_
_x000D_
.active>span:after {_x000D_
  content: ' ACTIVE';_x000D_
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.6.1/react.min.js"></script>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.6.1/react-dom.min.js"></script>_x000D_
<div id="app"></div>

Update: "Loops"

In response to a comment about a "loop" version, I believe the question is about rendering an array of MyClickable elements. We won't use a loop, but map, which is typical in React + JSX. The following should give you the same result as above, but it works with an array of elements.

// New render method for `Container`
render() {
  const clickables = [
    { name: "a" },
    { name: "b" },
    { name: "c" },
  ]

  return <div>
      { clickables.map(function(clickable, i) {
          return <MyClickable key={ clickable.name }
            name={ clickable.name }
            index={ i }
            isActive={ this.state.activeIndex === i }
            onClick={ this.handleClick }
          />
        } )
      }
  </div>
}

This code may help you

var sr = $("#Search Result");
sr.load("AJAX-Search.aspx?q=" + $("#q")
.val() + "&rnd=" + String((new Date).getTime())
.replace(/\D/gi, ""));

If I were doing this I would probably use WCF REST on the server and a REST library on the Java/Android client.

Sounds like you should stay with the defaults ;-)

Seriously: The number of maximum parallel connections you should set depends on your expected tomcat usage and also on the number of cores on your server. More cores on your processor => more parallel threads that can be executed.

See here how to configure...

Tomcat 9: https://tomcat.apache.org/tomcat-9.0-doc/config/executor.html

Tomcat 8: https://tomcat.apache.org/tomcat-8.0-doc/config/executor.html

A couple of issues arise when trying to reload/source ~/.profile file. [This refers to Ubuntu linux - in some cases the details of the commands will be different]

1. Are you running this directly in terminal or in a script?
2. How do you run this in a script?

Ad. 1)

Running this directly in terminal means that there will be no subshell created. So you can use either two commands:

source ~/.bash_profile

or

. ~/.bash_profile

In both cases this will update the environment with the contents of .profile file.

Ad 2) You can start any bash script either by calling

sh myscript.sh 

or

. myscript.sh

In the first case this will create a subshell that will not affect the environment variables of your system and they will be visible only to the subshell process. After finishing the subshell command none of the exports etc. will not be applied. THIS IS A COMMON MISTAKE AND CAUSES A LOT OF DEVELOPERS TO LOSE A LOT OF TIME.

In order for your changes applied in your script to have effect for the global environment the script has to be run with

.myscript.sh

command.

In order to make sure that you script is not runned in a subshel you can use this function. (Again example is for Ubuntu shell)

#/bin/bash

preventSubshell(){
  if [[ $_ != $0 ]]
  then
    echo "Script is being sourced"
  else
    echo "Script is a subshell - please run the script by invoking . script.sh command";
    exit 1;
  fi
}

I hope this clears some of the common misunderstandings! :D Good Luck!

theharshest answered the question but here is another way to do the same thing. Also, In your example you have NAME in caps and in your code you have name in lowercase.

s = '<div class="question" id="get attrs" name="python" x="something">Hello World</div>'
soup = BeautifulSoup(s)

attributes_dictionary = soup.find('div').attrs
print attributes_dictionary
# prints: {'id': 'get attrs', 'x': 'something', 'class': ['question'], 'name': 'python'}

print attributes_dictionary['class'][0]
# prints: question

print soup.find('div').get_text()
# prints: Hello World

You can upload those .py files to Google drive and allow Colab to use to them:

!mkdir -p drive
!google-drive-ocamlfuse drive

All your files and folders in root folder will be in drive.

I was looking for a way how to output a formatted time with minimal code, so here is my solution. Many people use Pandas anyway, so in some cases this can save from additional library imports.

import pandas as pd
start = pd.Timestamp.now()
# code
print(pd.Timestamp.now()-start)

Output:

0 days 00:05:32.541600

I would recommend using this if time precision is not the most important, otherwise use time library:

%timeit pd.Timestamp.now() outputs 3.29 µs ± 214 ns per loop

%timeit time.time() outputs 154 ns ± 13.3 ns per loop

JAutoDoc:

an Eclipse Plugin for automatically adding Javadoc and file headers to your source code. It optionally generates initial comments from element name by using Velocity templates for Javadoc and file headers...

To check if an element contains a class, you use the contains() method of the classList property of the element:*

element.classList.contains(className);

*Suppose you have the following element:

<div class="secondary info">Item</div>*

To check if the element contains the secondary class, you use the following code:

 const div = document.querySelector('div');
 div.classList.contains('secondary'); // true

The following returns false because the element doesn’t have the class error:

 const div = document.querySelector('div');
 div.classList.contains('error'); // false

TextView textv = (TextView) findViewById(R.id.textview1);
textv.setShadowLayer(1, 0, 0, Color.BLACK);

Put and Patch method are similar . But in rails it has different metod If we want to update/replace whole record then we have to use Put method. If we want to update particular record use Patch method.

Seems your selector is wrong, try using:

a.button:hover{
     background: #383;
}

Your code

a.button a:hover

Means it is going to search for an a element inside a with class button.

I had a situation where I needed two 'if' statements that could both go true and an 'else' or default if neither were true, not sure if this is an improvement on Jossef's answer but it seemed cleaner to me:

ng-class="{'class-one' : value.one , 'class-two' : value.two}" class="else-class"

Where value.one and value.two are true, they take precedent over the .else-class

Be sure that the tag "php" is stick in the code like this:

?php phpinfo(); ?>

Not like this:

? php phpinfo(); ?>

OR the server will treat it as a (normal word), so the server will not understand the language you are writing to deal with it so it will be blank.

I know it's a silly error ...but it happened ^_^

You can also get control of grand parent index by the following code

$parent.$parent.$index

There is an XML value alpha that takes double values.

Since API 11+ the range is from 0f to 1f (inclusive), 0f being transparent and 1f being opaque:

• android:alpha="0.0" thats invisible

• android:alpha="0.5" see-through

• android:alpha="1.0" full visible

That's how it works.

Step 1: Find the config.inc.php file located in the phpmyadmin directory. In my case it is located here:

C:\wamp\apps\phpmyadmin3.4.5\config.inc.php 

Note: phymyadmin3.4.5 folder name is different in different version of wamp

Step 2: Find the line with $cfg['UploadDir'] on it and update it to:

$cfg['UploadDir'] = 'upload';

Step 3: Create a directory called ‘upload’ within the phpmyadmin directory.

C:\wamp\apps\phpmyadmin3.2.0.1\upload\

Step 4: Copy and paste the large sql file into upload directory which you want importing to phymyadmin

Step 5: Select sql file from drop down list from phymyadmin to import.

Use function for multilevel loops - this is good way:

function find_dup () {
    for (;;) {
        for(;;) {
            if (done) return;
        }
    }
}

In addition to the other responses:

Once obtained, Access Tokens are typically sent along with every request from Clients to protected Resource Servers. This induce a risk for access token stealing and replay (assuming of course that access tokens are of type "Bearer" (as defined in the initial RFC6750).

Examples of those risks, in real life:

• Resource Servers generally are distributed application servers and typically have lower security levels compared to Authorization Servers (lower SSL/TLS config, less hardening, etc.). Authorization Servers on the other hand are usually considered as critical Security infrastructure and are subject to more severe hardening.

• Access Tokens may show up in HTTP traces, logs, etc. that are collected legitimately for diagnostic purposes on the Resource Servers or clients. Those traces can be exchanged over public or semi-public places (bug tracers, service-desk, etc.).

• Backend RS applications can be outsourced to more or less trustworthy third-parties.

The Refresh Token, on the other hand, is typically transmitted only twice over the wires, and always between the client and the Authorization Server: once when obtained by client, and once when used by client during refresh (effectively "expiring" the previous refresh token). This is a drastically limited opportunity for interception and replay.

Last thought, Refresh Tokens offer very little protection, if any, against compromised clients.

I don't see any reason why it would be a bad practice PROVIDED that you want to complete STOP processing at that point.

header($_SERVER['SERVER_PROTOCOL'] . ' 500 Internal Server Error', true, 500);

You put them in the workspace/projects folder. You should put them directly in the workspace folder and then do an Import Existing Projects into workspace.

This is the problem

double a[] = null;

Since a is null, NullPointerException will arise every time you use it until you initialize it. So this:

a[i] = var;

will fail.

A possible solution would be initialize it when declaring it:

double a[] = new double[PUT_A_LENGTH_HERE]; //seems like this constant should be 7

IMO more important than solving this exception, is the fact that you should learn to read the stacktrace and understand what it says, so you could detect the problems and solve it.

java.lang.NullPointerException

This exception means there's a variable with null value being used. How to solve? Just make sure the variable is not null before being used.

at twoten.TwoTenB.(TwoTenB.java:29)

This line has two parts:

• First, shows the class and method where the error was thrown. In this case, it was at <init> method in class TwoTenB declared in package twoten. When you encounter an error message with SomeClassName.<init>, means the error was thrown while creating a new instance of the class e.g. executing the constructor (in this case that seems to be the problem).
• Secondly, shows the file and line number location where the error is thrown, which is between parenthesis. This way is easier to spot where the error arose. So you have to look into file TwoTenB.java, line number 29. This seems to be a[i] = var;.

From this line, other lines will be similar to tell you where the error arose. So when reading this:

at javapractice.JavaPractice.main(JavaPractice.java:32)

It means that you were trying to instantiate a TwoTenB object reference inside the main method of your class JavaPractice declared in javapractice package.

For me, I usually use DataContext together in order to bind two-depth property such as this question.

<TextBlock DataContext="{Binding SelectedRule}" Text="{Binding Name}" />

Or, I prefer to use ElementName because it achieves bindings only with view controls.

<TextBlock DataContext="{Binding ElementName=lbRules, Path=SelectedItem}" Text="{Binding Name}" />

import java.util.Calendar;

Calendar cal = Calendar.getInstance();
int currentHour = cal.get(Calendar.HOUR);
if (currentHour > 10 && currentHour < 18) {
    //then rock on
}

Try to use Action class to reach the element

Actions action = new Actions(driver);
action.MoveToElement(driver.findElement(By.xpath("//a[text()='AppConfiguration']")));
action.Perform();

You can also try the following project that aims to help use that api. It's here:https://github.com/MathiasSeguy-Android2EE/GDirectionsApiUtils

How it works, definitly simply:

public class MainActivity extends ActionBarActivity implements DCACallBack{
/**
 * Get the Google Direction between mDevice location and the touched location using the     Walk
 * @param point
 */
private void getDirections(LatLng point) {
     GDirectionsApiUtils.getDirection(this, mDeviceLatlong, point,     GDirectionsApiUtils.MODE_WALKING);
}

/*
 * The callback
 * When the direction is built from the google server and parsed, this method is called and give you the expected direction
 */
@Override
public void onDirectionLoaded(List<GDirection> directions) {        
    // Display the direction or use the DirectionsApiUtils
    for(GDirection direction:directions) {
        Log.e("MainActivity", "onDirectionLoaded : Draw GDirections Called with path " + directions);
        GDirectionsApiUtils.drawGDirection(direction, mMap);
    }
}

I found this line worked best for one of my Windows Server 2008 R2 servers. A couple of others had no issues without this line in my PowerShell scripts:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Force -Scope Process

select tab1.name,
count(distinct tab2.id) as tab2_record_count
count(distinct tab3.id) as tab3_record_count
count(distinct tab4.id) as tab4_record_count
from tab1
left join tab2 on tab2.tab1_id = tab1.id
left join tab3 on tab3.tab1_id = tab1.id
left join tab4 on tab4.tab1_id = tab1.id

What worked for me after following all your workarounds was to call the API:

 <script async defer src="https://maps.googleapis.com/maps/api/js?key=you_API_KEY&callback=initMap&libraries=places"
            type="text/javascript"></script>

before my : <div id="map"></div>

I am using .ASP NET (MVC)

To avoid strange side-effects with closures in java variables referenced by an anonymous delegate must be marked as final, so to refer to lastPrice and price within the timer task they need to be marked as final.

This obviously won't work for you because you wish to change them, in this case you should look at encapsulating them within a class.

public class Foo {
    private PriceObject priceObject;
    private double lastPrice;
    private double price;

    public Foo(PriceObject priceObject) {
        this.priceObject = priceObject;
    }

    public void tick() {
        price = priceObject.getNextPrice(lastPrice);
        lastPrice = price;
    }
}

now just create a new Foo as final and call .tick from the timer.

public static void main(String args[]){
    int period = 2000;
    int delay = 2000;

    Price priceObject = new Price();
    final Foo foo = new Foo(priceObject);

    Timer timer = new Timer();
    timer.scheduleAtFixedRate(new TimerTask() {
        public void run() {
            foo.tick();
        }
    }, delay, period);
}

In case of adding new rows for array in loop, Assign the array directly for firsttime in loop instead of initialising an empty array.

for i in range(0,len(0,100)):
    SOMECALCULATEDARRAY = .......
    if(i==0):
        finalArrayCollection = SOMECALCULATEDARRAY
    else:
        finalArrayCollection = np.vstack(finalArrayCollection,SOMECALCULATEDARRAY)

This is mainly useful when the shape of the array is unknown

If lakes is your DataFrame, you can do something like

area_dict = dict(zip(lakes.area, lakes.count))

You can increase client_max_body_size and upload_max_filesize + post_max_size all day long. Without adjusting HTTP timeout it will never work.

//You need to adjust this, and probably on PHP side also. client_body_timeout 2min // 1GB fileupload

SELECT d1.Short_Code 
FROM domain1 d1
LEFT JOIN domain2 d2
ON d1.Short_Code = d2.Short_Code
WHERE d2.Short_Code IS NULL

You can get the screenshot of a division and save it easily just using the below snippet. Here I'm used the entire body, you can choose the specific image/div elements just by putting the id/class names.

 html2canvas(document.getElementsByClassName("image-div")[0], {
  useCORS: true,
}).then(function (canvas) {
  var imageURL = canvas.toDataURL("image/png");
  let a = document.createElement("a");
  a.href = imageURL;
  a.download = imageURL;
  a.click();
});

It was changing the line endings (from Windows CRLF to Unix LF) in the .htaccess file that fixed it for me.

select controls are still clickable even on readonly attrib

if you want to still disable the control but you want its value posted. You might consider creating a hidden field. with the same value as your control.

then create a jquery, on select change

$('#your_select_id').change(function () {
    $('#your_hidden_selectid').val($('#your_select_id').val());
});

1. Go to your Android project directory

   C:\Users\HP\AndroidStudioProjects
   

   

2. Delete which one you need to delete

3. Restart Android Studio

String all = "";
        try {
            BufferedReader br = new BufferedReader(new FileReader(filePath));
            String strLine;
            while ((strLine = br.readLine()) != null){
                all = all + strLine;
            }
        } catch (IOException e) {
            Log.e("notes_err", e.getLocalizedMessage());
        }

An alternative approach would be to "emulate" bold text via text-shadow. This has the bonus (/malus, depending on your case) to work also on font icons.

   nav li a:hover {
      text-decoration: none;
      text-shadow: 0 0 1px; /* "bold" */
   }

Kinda hacky, although it saves you from duplicating text (which is useful if it is a lot, as it was in my case).

String in java is immutable. So whenever a string is created, it will remain in the memory until it is garbage collected. So anyone who has access to the memory can read the value of the string.
If the value of the string is modified then it will end up creating a new string. So both the original value and the modified value stay in the memory until it is garbage collected.

With the character array, the contents of the array can be modified or erased once the purpose of the password is served. The original contents of the array will not be found in memory after it is modified and even before the garbage collection kicks in.

Because of the security concern it is better to store password as a character array.

You can convert Date to almost any format using the Snippet I have added below.

Code:

dateFormat(new Date(),"dd/mm/yy h:MM TT")
//"20/06/14 6:49 PM"

Other examples

// Can also be used as a standalone function
dateFormat(new Date(), "dddd, mmmm dS, yyyy, h:MM:ss TT");
// Saturday, June 9th, 2007, 5:46:21 PM

dateFormat(new Date(),"dddd d mmmm yyyy")
//Monday 2 June 2014"

Snippet:

Add following code taken from this link into your code.

var dateFormat = function () {
    var token = /d{1,4}|m{1,4}|yy(?:yy)?|([HhMsTt])\1?|[LloSZ]|"[^"]*"|'[^']*'/g,
        timezone = /\b(?:[PMCEA][SDP]T|(?:Pacific|Mountain|Central|Eastern|Atlantic) (?:Standard|Daylight|Prevailing) Time|(?:GMT|UTC)(?:[-+]\d{4})?)\b/g,
        timezoneClip = /[^-+\dA-Z]/g,
        pad = function (val, len) {
            val = String(val);

The only portable way to achieve consistency between rooms and tags and making sure rooms are never returned after they had been deleted is locking them with SELECT FOR UPDATE.

However in some systems locking is a side effect of concurrency control, and you achieve the same results without specifying FOR UPDATE explicitly.

To solve this problem, Thread 1 should SELECT id FROM rooms FOR UPDATE, thereby preventing Thread 2 from deleting from rooms until Thread 1 is done. Is that correct?

This depends on the concurrency control your database system is using.

• MyISAM in MySQL (and several other old systems) does lock the whole table for the duration of a query.

• In SQL Server, SELECT queries place shared locks on the records / pages / tables they have examined, while DML queries place update locks (which later get promoted to exclusive or demoted to shared locks). Exclusive locks are incompatible with shared locks, so either SELECT or DELETE query will lock until another session commits.

• In databases which use MVCC (like Oracle, PostgreSQL, MySQL with InnoDB), a DML query creates a copy of the record (in one or another way) and generally readers do not block writers and vice versa. For these databases, a SELECT FOR UPDATE would come handy: it would lock either SELECT or the DELETE query until another session commits, just as SQL Server does.

When should one use REPEATABLE_READ transaction isolation versus READ_COMMITTED with SELECT ... FOR UPDATE?

Generally, REPEATABLE READ does not forbid phantom rows (rows that appeared or disappeared in another transaction, rather than being modified)

• In Oracle and earlier PostgreSQL versions, REPEATABLE READ is actually a synonym for SERIALIZABLE. Basically, this means that the transaction does not see changes made after it has started. So in this setup, the last Thread 1 query will return the room as if it has never been deleted (which may or may not be what you wanted). If you don't want to show the rooms after they have been deleted, you should lock the rows with SELECT FOR UPDATE

• In InnoDB, REPEATABLE READ and SERIALIZABLE are different things: readers in SERIALIZABLE mode set next-key locks on the records they evaluate, effectively preventing the concurrent DML on them. So you don't need a SELECT FOR UPDATE in serializable mode, but do need them in REPEATABLE READ or READ COMMITED.

Note that the standard on isolation modes does prescribe that you don't see certain quirks in your queries but does not define how (with locking or with MVCC or otherwise).

When I say "you don't need SELECT FOR UPDATE" I really should have added "because of side effects of certain database engine implementation".

MySQL documentation covers this topic.

Here is a synopsis. When using join or inner join, the on condition is optional. This is different from the ANSI standard and different from almost any other database. The effect is a cross join. Similarly, you can use an on clause with cross join, which also differs from standard SQL.

A cross join creates a Cartesian product -- that is, every possible combination of 1 row from the first table and 1 row from the second. The cross join for a table with three rows ('a', 'b', and 'c') and a table with four rows (say 1, 2, 3, 4) would have 12 rows.

In practice, if you want to do a cross join, then use cross join:

from A cross join B

is much better than:

from A, B

and:

from A join B -- with no on clause

The on clause is required for a right or left outer join, so the discussion is not relevant for them.

If you need to understand the different types of joins, then you need to do some studying on relational databases. Stackoverflow is not an appropriate place for that level of discussion.

you will get the time without specifying the date format. convert the string to date using Date object

var myDate = new Date('Mon 03-Jul-2017, 06:00 PM');

working solution:

var myDate= new Date('Mon 03-Jul-2017, 06:00 PM');_x000D_
console.log(moment(myDate).format('HH:mm')); // 24 hour format _x000D_
console.log(moment(myDate).format('hh:mm'));_x000D_
console.log(moment(myDate).format('hh:mm A'));

If you want the default colors of Android ICS, you just have to go to your Android SDK and look for this path: platforms\android-15\data\res\values\colors.xml.

Here you go:

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

1. If foo echo yes else echo no:

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

2. If foo echo it, else echo no:

   {{ foo ?: 'no' }}
   

   or

   {{ foo ? foo : 'no' }}
   

3. If foo echo yes else echo nothing:

   {{ foo ? 'yes' }}
   

   or

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

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

   {{ foo ?? 'no' }}
   

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

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

If you are using Eclipse then go to Windows -> Preferences -> Maven and uncheck the "Do not automatically update dependencies from remote repositories" checkbox.

This works with Maven 3 as well.

Use this code:

The answer that worked for me was indeed what OP mentions in his 2015 update: uncheck these two boxes in your Python run config:

• "Add content roots to PYTHONPATH"
• "Add source roots to PYTHONPATH"

I already had the run config set to use the proper venv, so PyCharm doing additional work to add things to the path was not necessary. Instead it was causing errors.

I did everything above but had to do one more thing in IntelliJ:

Project Structure > Modules

I had to change every module's "language level"

What I have here is a "center" method that ensures the element you are attempting to center is not only of "fixed" or "absolute" positioning, but it also ensures that the element you are centering is smaller than its parent, this centers and element relative to is parent, if the elements parent is smaller than the element itself, it will pillage up the DOM to the next parent, and center it relative to that.

$.fn.center = function () {
        /// <summary>Centers a Fixed or Absolute positioned element relative to its parent</summary>

        var element = $(this),
            elementPos = element.css('position'),
            elementParent = $(element.parent()),
            elementWidth = element.outerWidth(),
            parentWidth = elementParent.width();

        if (parentWidth <= elementWidth) {
            elementParent = $(elementParent.parent());
            parentWidth = elementParent.width();
        }

        if (elementPos === "absolute" || elementPos === "fixed") {
            element.css('right', (parentWidth / 2) - elementWidth / 2 + 'px');
        }
    };

As stated in other answers, the simplest method is to uniquely identify the root element (by ID or class name) and use the direct descendent selector.

$('ul.topMenu > li > a')

However, I came across this question in search of a solution which would work on unnamed elements at varying depths of the DOM.

This can be achieved by checking each element, and ensuring it does not have a parent in the list of matched elements. Here is my solution, wrapped in a jQuery selector 'topmost'.

jQuery.extend(jQuery.expr[':'], {
  topmost: function (e, index, match, array) {
    for (var i = 0; i < array.length; i++) {
      if (array[i] !== false && $(e).parents().index(array[i]) >= 0) {
        return false;
      }
    }
    return true;
  }
});

Utilizing this, the solution to the original post is:

$('ul:topmost > li > a')

// Or, more simply:
$('li:topmost > a')

Complete jsFiddle available here.

I faced the same error with my Visual Studio Team Services account (formerly Visual Studio Online, Team Foundation Service).

I simply entered the credentials using the VS 2013 "Connect to Team Foundation Server" Window, and then connected it to the Visual Studio Team Services Team Project. It worked this way.

Short answer: 400-800 pixels.

What I have read is that HTML newsletter width should be as narrow as possible without being too narrow. For instance, 400-500 pixels for a one column layout is a lower limit. Any less may look too weird.

Today's widescreen monitors allow for more horizontal pixels and most web email clients will either be of the two-column variety (Gmail) or 3-pane layout where the content window bellow the inbox list (Hotmail and Yahoo). In either case, you can be okay with 800 pixels if you're targeting the 1280 wide audience. An older or less technical audience may have older, square monitors.

There is the problem of Outlook having a three-column layout. That limits the width of your email even more. With them, you may want to go even narrower.

I just recently created a template that required an ad banner that is 730 pixels wide. It was near in the wide range, but not so much that most people could not double-click the email an open a new window in Outlook (the web email users should be okay for the most part).

Hope this advice helps.

Oh, there are tons of example. Just have a look at anything within glib or gtk. You can see the work of function pointers in work there all the way.

Here e.g the initialization of the gtk_button stuff.

static void
gtk_button_class_init (GtkButtonClass *klass)
{
  GObjectClass *gobject_class;
  GtkObjectClass *object_class;
  GtkWidgetClass *widget_class;
  GtkContainerClass *container_class;

  gobject_class = G_OBJECT_CLASS (klass);
  object_class = (GtkObjectClass*) klass;
  widget_class = (GtkWidgetClass*) klass;
  container_class = (GtkContainerClass*) klass;

  gobject_class->constructor = gtk_button_constructor;
  gobject_class->set_property = gtk_button_set_property;
  gobject_class->get_property = gtk_button_get_property;

And in gtkobject.h you find the following declarations:

struct _GtkObjectClass
{
  GInitiallyUnownedClass parent_class;

  /* Non overridable class methods to set and get per class arguments */
  void (*set_arg) (GtkObject *object,
           GtkArg    *arg,
           guint      arg_id);
  void (*get_arg) (GtkObject *object,
           GtkArg    *arg,
           guint      arg_id);

  /* Default signal handler for the ::destroy signal, which is
   *  invoked to request that references to the widget be dropped.
   *  If an object class overrides destroy() in order to perform class
   *  specific destruction then it must still invoke its superclass'
   *  implementation of the method after it is finished with its
   *  own cleanup. (See gtk_widget_real_destroy() for an example of
   *  how to do this).
   */
  void (*destroy)  (GtkObject *object);
};

The (*set_arg) stuff is a pointer to function and this can e.g be assigned another implementation in some derived class.

Often you see something like this

struct function_table {
   char *name;
   void (*some_fun)(int arg1, double arg2);
};

void function1(int  arg1, double arg2)....


struct function_table my_table [] = {
    {"function1", function1},
...

So you can reach into the table by name and call the "associated" function.

Or maybe you use a hash table in which you put the function and call it "by name".

You could try passing a callback function to perform the replacement:

var tagsToReplace = {
    '&': '&',
    '<': '&lt;',
    '>': '&gt;'
};

function replaceTag(tag) {
    return tagsToReplace[tag] || tag;
}

function safe_tags_replace(str) {
    return str.replace(/[&<>]/g, replaceTag);
}

Here is a performance test: http://jsperf.com/encode-html-entities to compare with calling the replace function repeatedly, and using the DOM method proposed by Dmitrij.

Your way seems to be faster...

Why do you need it, though?

Use the createFromFormat method:

$start_date = DateTime::createFromFormat("U", $dbResult->db_timestamp);

UPDATE

I now recommend the use of Carbon

This is a great chance to introduce you to the File Exchange. Though the organization of late has suffered from some very unfortunately interface design choices, it is still a great resource for pre-packaged solutions to common problems. Though many here have given you the gory details of how to achieve this (@prm!), I had a similar need a few years ago and found that addaxis worked very well. (It was a File Exchange pick of the week at one point!) It has inspired later, probably better mods. Here is some example output:

addaxis example http://www.mathworks.com/matlabcentral/fx_files/9016/1/addaxis_screenshot.jpg

I just searched for "plotyy" at File Exchange.

Though understanding what's going on in important, sometimes you just need to get things done, not do them yourself. Matlab Central is great for that.

You can make use of the following code incase you want to check the types of primitive data types.

// Returns 0 if the object type is equal to double
strcmp([myNumber objCType], @encode(double)) 

They have wrapped most stuff need to solve your problem, one of the tests looks like this:

String filename = CSSURLEmbedderTest.class.getResource("folder.png").getPath().replace("%20", " ");
String code = "background: url(folder.png);";

StringWriter writer = new StringWriter();
embedder = new CSSURLEmbedder(new StringReader(code), true);
embedder.embedImages(writer, filename.substring(0, filename.lastIndexOf("/")+1));

String result = writer.toString();
assertEquals("background: url(" + folderDataURI + ");", result);

Schema in SQL Server is an object that conceptually holds definitions for other database objects such as tables,views,stored procedures etc.

If you are simply looking to make the input relative to the screen width, an easy way would be to use Dimensions:

// De structure Dimensions from React
var React = require('react-native');
var {
  ...
  Dimensions
} = React; 

// Store width in variable
var width = Dimensions.get('window').width; 

// Use width variable in style declaration
<TextInput style={{ width: width * .8 }} />

I've set up a working project here. Code is also below.

https://rnplay.org/apps/rqQPCQ

'use strict';

var React = require('react-native');
var {
  AppRegistry,
  StyleSheet,
  Text,
  View,
  TextInput,
  Dimensions
} = React;

var width = Dimensions.get('window').width;

var SampleApp = React.createClass({
  render: function() {
    return (
      <View style={styles.container}>
        <Text style={{fontSize:22}}>Percentage Width In React Native</Text>
        <View style={{marginTop:100, flexDirection: 'row',justifyContent: 'center'}}>
            <TextInput style={{backgroundColor: '#dddddd', height: 60, width: width*.8 }} />
          </View>
      </View>
    );
  }
});

var styles = StyleSheet.create({
  container: {
    flex: 1,
    marginTop:100
  },

});

AppRegistry.registerComponent('SampleApp', () => SampleApp);

For logout button on last screen of app, use this code on logout button listener to finish all open previous activities, and your problem is solved.

{
Intent intent = new Intent(this, loginScreen.class);
ntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);
}

This can be accomplished by Unmarshaling into a map[string]json.RawMessage.

var objmap map[string]json.RawMessage
err := json.Unmarshal(data, &objmap)

To further parse sendMsg, you could then do something like:

var s sendMsg
err = json.Unmarshal(objmap["sendMsg"], &s)

For say, you can do the same thing and unmarshal into a string:

var str string
err = json.Unmarshal(objmap["say"], &str)

EDIT: Keep in mind you will also need to export the variables in your sendMsg struct to unmarshal correctly. So your struct definition would be:

type sendMsg struct {
    User string
    Msg  string
}

Example: https://play.golang.org/p/OrIjvqIsi4-

Here are the steps:

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

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

Did you actually set up your specific user? The walkthrough setup guide in AWS explains how to set a default user, and then how to set up additional users. If you didn't complete the full setup, you'll just have a default block and your myName won't have been created..

$('input, select').attr('disabled', 'disabled');

I have another solution for your question .

In the first when use date the output is like this :

Thu 28 Jan 2021 22:29:40 IST

Then if you want only to show current time in hours and minutes you can use this command :

date | cut -d " " -f5 | cut -d ":" -f1-2 

Then the output :

22:29

If by string you mean std::string you can do it with this method:

QString QString::fromStdString(const std::string & str)

std::string str = "Hello world";
QString qstr = QString::fromStdString(str);

If by string you mean Ascii encoded const char * then you can use this method:

QString QString::fromAscii(const char * str, int size = -1)

const char* str = "Hello world";
QString qstr = QString::fromAscii(str);

If you have const char * encoded with system encoding that can be read with QTextCodec::codecForLocale() then you should use this method:

QString QString::fromLocal8Bit(const char * str, int size = -1)

const char* str = "zazólc gesla jazn";      // latin2 source file and system encoding
QString qstr = QString::fromLocal8Bit(str);

If you have const char * that's UTF8 encoded then you'll need to use this method:

QString QString::fromUtf8(const char * str, int size = -1)

const char* str = read_raw("hello.txt"); // assuming hello.txt is UTF8 encoded, and read_raw() reads bytes from file into memory and returns pointer to the first byte as const char*
QString qstr = QString::fromUtf8(str);

There's also method for const ushort * containing UTF16 encoded string:

QString QString::fromUtf16(const ushort * unicode, int size = -1)

const ushort* str = read_raw("hello.txt"); // assuming hello.txt is UTF16 encoded, and read_raw() reads bytes from file into memory and returns pointer to the first byte as const ushort*
QString qstr = QString::fromUtf16(str);

I have faced same problem and It will resolve this issue in all android versions

private void setCookie() {
    try {
        CookieSyncManager.createInstance(context);
        CookieManager cookieManager = CookieManager.getInstance();
        cookieManager.setAcceptCookie(true);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            cookieManager.setCookie(Constant.BASE_URL, getCookie(), value -> {
                String cookie = cookieManager.getCookie(Constant.BASE_URL);
                CookieManager.getInstance().flush();
                CustomLog.d("cookie", "cookie ------>" + cookie);
                setupWebView();
            });
        } else {
            cookieManager.setCookie(webUrl, getCookie());
            new Handler().postDelayed(this::setupWebView, 700);
            CookieSyncManager.getInstance().sync();
        }

    } catch (Exception e) {
        CustomLog.e(e);
    }
}

split doesn't work that way in groovy. you have to use tokenize...

See the docs:

http://groovy-lang.org/gdk.html#split()

Setting \itemindent for a new itemize environment solves the problem:

\newenvironment{beameritemize}
{ \begin{itemize}
  \setlength{\itemsep}{1.5ex}
  \setlength{\parskip}{0pt}
  \setlength{\parsep}{0pt}   
  \addtolength{\itemindent}{-2em}  }
{ \end{itemize} } 

Yes, they are different and while many people have made a great suggestion of using console.log to see for yourself. However, I didn't see anyone mention event.location that you can use that to determine if the number is coming from the keypad event.location === 3 vs the top of the main keyboard / general keys event.location === 0. This approach would be best suited for when you need to generally determine if keystrokes are coming from a region of the keyboard or not, event.key is likely better for the specific keys.

In SQL Server , cast text as datetime

select cast('5/21/2013 9:45:48' as datetime)

OUTDATED - see this answer for a simpler approach

To obtain readable x tick labels without additional dependencies, you want to use:

  ... +
  theme(axis.text.x = element_text(angle = 90, hjust = 1, vjust = 0.5)) +
  ...

This rotates the tick labels 90° counterclockwise and aligns them vertically at their end (hjust = 1) and their centers horizontally with the corresponding tick mark (vjust = 0.5).

Full example:

library(ggplot2)
data(diamonds)
diamonds$cut <- paste("Super Dee-Duper",as.character(diamonds$cut))
q <- qplot(cut,carat,data=diamonds,geom="boxplot")
q + theme(axis.text.x = element_text(angle = 90, hjust = 1, vjust = 0.5))

Note, that vertical/horizontal justification parameters vjust/hjust of element_text are relative to the text. Therefore, vjust is responsible for the horizontal alignment.

Without vjust = 0.5 it would look like this:

q + theme(axis.text.x = element_text(angle = 90, hjust = 1))

Without hjust = 1 it would look like this:

q + theme(axis.text.x = element_text(angle = 90, vjust = 0.5))

If for some (wired) reason you wanted to rotate the tick labels 90° clockwise (such that they can be read from the left) you would need to use: q + theme(axis.text.x = element_text(angle = -90, vjust = 0.5, hjust = -1)).

All of this has already been discussed in the comments of this answer but I come back to this question so often, that I want an answer from which I can just copy without reading the comments.

To create elements with equal width using Flex, you should set to your's child (flex elements):

flex-basis: 25%;
flex-grow: 0;

It will give to all elements in row 25% width. They will not grow and go one by one.

Without punctuation (as @Burusothman has mentioned):

current_date_time="`date +%Y%m%d%H%M%S`";
echo $current_date_time;

O/P:

20170115072120

With punctuation:

current_date_time="`date "+%Y-%m-%d %H:%M:%S"`";
echo $current_date_time;

O/P:

2017-01-15 07:25:33

Since Spring Boot 1.5, you can complete ignore the error-prone string literal in pom or build.gradle. The repackaging tool (via maven or gradle plugin) will pick the one annotated with @SpringBootApplication for you. (Refer to this issue for detail: https://github.com/spring-projects/spring-boot/issues/6496 )

I recently had to revert to a particular revision to debug an older build and this worked like magic:

svn up -r 3340 (or what ever your desired revision number)

I had to resolve all conflicts using "tc" option as I did not care about local changes (checked in everything I cared about prior to reverting)

To get back to head revision was simple too:

svn up

protected bool CheckIfPalindrome(string text)
{
    if (text != null)
    {
        string strToUpper = Text.ToUpper();
        char[] toReverse = strToUpper.ToCharArray();
        Array.Reverse(toReverse );
        String strReverse = new String(toReverse);
        if (strToUpper == toReverse)
        {
            return true;
        }
        else
        {
            return false;
        }
    }
    else
    {
        return false;
    }
}

Use this the sipmlest way.

It allows you to read from the standard input (mainly, the console). This SO question may helps you.

Both ways are viable, but they do different things when it comes to inheritance with an overridden static method. Choose the one whose behavior you expect:

class Super {
  static whoami() {
    return "Super";
  }
  lognameA() {
    console.log(Super.whoami());
  }
  lognameB() {
    console.log(this.constructor.whoami());
  }
}
class Sub extends Super {
  static whoami() {
    return "Sub";
  }
}
new Sub().lognameA(); // Super
new Sub().lognameB(); // Sub

Referring to the static property via the class will be actually static and constantly give the same value. Using this.constructor instead will use dynamic dispatch and refer to the class of the current instance, where the static property might have the inherited value but could also be overridden.

This matches the behavior of Python, where you can choose to refer to static properties either via the class name or the instance self.

If you expect static properties not to be overridden (and always refer to the one of the current class), like in Java, use the explicit reference.

For those who may be running WAMP 3.1.4 with Apache 2.4.35 on Windows 10 (64-bit)

If you're having issues with external devices connecting to your localhost, and receiving a 403 Forbidden error, it may be an issue with your httpd.conf and the httpd-vhosts.conf files and the "Require local" line they both have within them.

[Before] httpd-vhosts.conf

<VirtualHost *:80>
 ServerName localhost
 ServerAlias localhost
 DocumentRoot "${INSTALL_DIR}/www"
 <Directory "${INSTALL_DIR}/www/">
   Options +Indexes +Includes +FollowSymLinks +MultiViews
   AllowOverride All
   Require local     <--- This is the offending line.
 </Directory>
</VirtualHost>

[After] httpd-vhosts.conf

<VirtualHost *:80>
 ServerName localhost
 ServerAlias localhost
 DocumentRoot "${INSTALL_DIR}/www"
 <Directory "${INSTALL_DIR}/www/">
   Options +Indexes +Includes +FollowSymLinks +MultiViews
   AllowOverride All
 </Directory>
</VirtualHost>

Additionally, you'll need to update your httpd.conf file as follows:

[Before] httpd.conf

DocumentRoot "${INSTALL_DIR}/www"
<Directory "${INSTALL_DIR}/www/">
#   onlineoffline tag - don't remove

    Require local  #<--- This is the offending line.
</Directory>

[After] httpd.conf

DocumentRoot "${INSTALL_DIR}/www"
<Directory "${INSTALL_DIR}/www/">
#   onlineoffline tag - don't remove

#   Require local
</Directory>

Make sure to restart your WAMP server via (System tray at bottom-right of screen --> left-click WAMP icon --> "Restart all Services").

Then refresh your machine's browser on localhost to ensure you've still got proper connectivity there, and then refresh your other external devices that you were previously attempting to connect.

Disclaimer: If you're in a corporate setting, this is untested from a security perspective; please ensure you're keenly aware of your local development environment's access protocols before implementing any sweeping changes.

Typically you add a class selector to the :not() pseudo-class like so:

:not(.printable) {
    /* Styles */
}

:not([attribute]) {
    /* Styles */
}

But if you need better browser support (IE8 and older don't support :not()), you're probably better off creating style rules for elements that do have the "printable" class. If even that isn't feasible despite what you say about your actual markup, you may have to work your markup around that limitation.

Keep in mind that, depending on the properties you're setting in this rule, some of them may either be inherited by descendants that are .printable, or otherwise affect them one way or another. For example, although display is not inherited, setting display: none on a :not(.printable) will prevent it and all of its descendants from displaying, since it removes the element and its subtree from layout completely. You can often get around this by using visibility: hidden instead which will allow visible descendants to show, but the hidden elements will still affect layout as they originally did. In short, just be careful.

One way is to use assert:

def myFunction(a,b,c):
    "This is an example function I'd like to check arguments of"
    assert isinstance(a, int), 'a should be an int'
    # or if you want to allow whole number floats: assert int(a) == a
    assert b > 0 and b < 10, 'b should be betwen 0 and 10'
    assert isinstance(c, str) and c, 'c should be a non-empty string'

For those getting blank/black screens this code worked for me.

    let vc = self.storyboard?.instantiateViewController(withIdentifier: myVCID) as! myVCName
    self.present(vc, animated: true, completion: nil)

To set the "Identifier" to your VC just go to identity inspector for the VC in the storyboard. Set the 'Storyboard ID' to what ever you want to identifier to be. Look at the image below for reference.

Other answers rightly point out that there is no need to use jQuery in order to navigate to another URL; that's why there's no jQuery function which does so!

If you're asking how to click a link via jQuery then assuming you have markup which looks like:

<a id="my-link" href="/relative/path.html">Click Me!</a>

You could click() it by executing:

$('#my-link').click();

You can compare for exactly the same type using:

class A {
}
var a = new A();
var typeOfa = a.GetType();
if (typeOfa == typeof(A)) {
}

typeof returns the Type object from a given class.

But if you have a type B, that inherits from A, then this comparison is false. And you are looking for IsAssignableFrom.

class B : A {
}
var b = new B();
var typeOfb = b.GetType();

if (typeOfb == typeof(A)) { // false
}

if (typeof(A).IsAssignableFrom(typeOfb)) { // true
}

Recursive solution for browsers that support ECMAScript 5:

var getObjectKeys = function(obj) {
    var keys = Object.keys(obj);
    var length = keys.length;

    if (length !== 0) {
        for (var i = 0; i < length; i++) {
            if (typeof obj[keys[i]] === 'object') {
                keys[keys[i]] = getObjectKeys(obj[keys[i]]);
            }
        }
    }

    return keys;
};

Try this::

sb_trim = Regex.Replace(stw, @"(\D+)\s+\$([\d,]+)\.\d+\s+(.)",
    m => string.Format(
        "{0},{1},{2}",
        m.Groups[1].Value,
        m.Groups[2].Value.Replace(",", string.Empty),
        m.Groups[3].Value));

This is about as clean an answer as you'll get, at least with regexes.

• (\D+): First capture group. One or more non-digit characters.
• \s+\$: One or more spacing characters, then a literal dollar sign ($).
• ([\d,]+): Second capture group. One or more digits and/or commas.
• \.\d+: Decimal point, then at least one digit.
• \s+: One or more spacing characters.
• (.): Third capture group. Any non-line-breaking character.

The second capture group additionally needs to have its commas stripped. You could do this with another regex, but it's really unnecessary and bad for performance. This is why we need to use a lambda expression and string format to piece together the replacement. If it weren't for that, we could just use this as the replacement, in place of the lambda expression:

"$1,$2,$3"

<asp:Panel ID="Panel2" runat="server" DefaultButton="bttxt">

SO what I change is I load upload library each time

                $config = array();
                $config['upload_path'] = $filePath;
                $config['allowed_types'] = 'gif|jpg|png';
                $config['max_size']      = '0';
                $config['overwrite']     = FALSE;

                $files = $_FILES;
                $count = count($_FILES['nameUpload']['name']);


                for($i=0; $i<$count; $i++)
                {
                    $this->load->library('upload', $config);

                    $_FILES['nameUpload']['name']= $files['nameUpload']['name'][$i];
                    $_FILES['nameUpload']['type']= $files['nameUpload']['type'][$i];
                    $_FILES['nameUpload']['tmp_name']= $files['nameUpload']['tmp_name'][$i];
                    $_FILES['nameUpload']['error']= $files['nameUpload']['error'][$i];
                    $_FILES['nameUpload']['size']= $files['nameUpload']['size'][$i];

                    $this->upload->do_upload('nameUpload');
                }

And it work for me.

You need to put the font file name / path in quotes.
Eg.

url("../fonts/Gotham-Medium.ttf")

or

url('../fonts/Gotham-Medium.ttf')

and not

url(../fonts/Gotham-Medium.ttf)

Also @FONT-FACE only works with some font files. :o(

All the sites where you can download fonts, never say which fonts work and which ones don't.

Without the combined child selector you would probably do something similar to this:

foo {
  bar {
    baz {
      color: red;
    }
  }
}

If you want to reproduce the same syntax with >, you could to this:

foo {
  > bar {
    > baz {
      color: red;
    }
  }
}

This compiles to this:

foo > bar > baz {
  color: red;
}

Or in sass:

foo
  > bar
    > baz
      color: red

Just put the DATABASE NAME in front of INFORMATION_SCHEMA.TABLES:

select table_name from YOUR_DATABASE.INFORMATION_SCHEMA.TABLES where TABLE_TYPE = 'BASE TABLE'

You can do this via a couple ways.

One is when you run your application, you can pass it a flag.

java -Dgate.home="http://gate.ac.uk/wiki/code-repository" your_application

Or set it programmatically in code before the piece of code that needs this property set. Java keeps a Properties object for System wide configuration.

Properties props = System.getProperties();
props.setProperty("gate.home", "http://gate.ac.uk/wiki/code-repository");

Setting android:background and android:button of the RadioButton like the accepted answer didn't work for me. The drawable image was being displayed as a background(eventhough android:button was being set to transparent ) to the radio button text as

android:background="@drawable/radiobuttonstyle"
    android:button="@android:color/transparent"

so gave radiobutton as the custom drawable radiobuttonstyle.xml

<RadioButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:checked="true"
    android:text="Maintenance"
    android:id="@+id/radioButton1"
    android:button="@drawable/radiobuttonstyle"
      />

and radiobuttonstyle.xml is as follows

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

and after this radiobutton with custom button style worked.

For the record, we had the same problem today. We fixed it by using this option:

-XX:-UseConcMarkSweepGC

Apparently, this modified the strategy used for garbage collection, which made the issue disappear.

Robi Code is work for me, just put if !null so that if phone number is null, user can fill the phone number by him/her self.

editTextPhoneNumber = (EditText) findViewById(R.id.editTextPhoneNumber);
TelephonyManager tMgr;
tMgr= (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
String mPhoneNumber = tMgr.getLine1Number();
if (mPhoneNumber != null){
editTextPhoneNumber.setText(mPhoneNumber);
}

Java is faster than Python. Easily.

Python is favorable for many things; speed isn't necessarily one of them.

You first Perl example doesn't look unreasonable to me.

It's for reasons like this that I migrated from writing shell scripts (in bash/sh etc.) to writing all but the most trivial scripts in Perl. I found that I was having to launch Perl for particular requirements, and as I did that more and more, I realised that writing the scripts in Perl was probably a more powerful (in terms of the language and the wide array of libraries available via CPAN) and more efficient way to achieve what I wanted.

Note that other shell-scripting languages (e.g. python/ruby) will no doubt have similar facilities, and you may want to evaluate these for your purposes. I only discuss Perl since that's the language I use and am familiar with.

You want to duplicate the behavior of an old HP calculator, there are two options:

1. You write new program that draws the calculator's display and keys, and when the user clicks on the keys, your programs does what the old calculator did. This is a Simulator

2. You get a dump of the calculator's firmware, then write a program that loads the firmware and interprets it the same way the microprocessor in the calculator did. This is an Emulator

The Simulator tries to duplicate the behavior of the device.
The Emulator tries to duplicate the inner workings of the device.

This works:

var form = $(this).closest('form');

form = form.serializeArray();

form = form.concat([
    {name: "customer_id", value: window.username},
    {name: "post_action", value: "Update Information"}
]);

$.post('/change-user-details', form, function(d) {
    if (d.error) {
        alert("There was a problem updating your user details")
    } 
});

In bootstrap 4 it is much easier to have a border on the fieldset that blends with the legend. You don't need custom css to achieve it, it can be done like this:

<fieldset class="border p-2">
   <legend  class="w-auto">Your Legend</legend>
</fieldset>

which looks like this:

Syntax errors is not checked easily in external servers, just runtime errors.

What I do? Just like you, I use

ini_set('display_errors', 'On');
error_reporting(E_ALL);

However, before run I check syntax errors in a PHP file using an online PHP syntax checker.

The best, IMHO is PHP Code Checker

I copy all the source code, paste inside the main box and click the Analyze button.

It is not the most practical method, but the 2 procedures are complementary and it solves the problem completely

This checks if the array is empty

if (!empty($result) {
    // do stuf if array is not empty
} else {
    // do stuf if array is empty
}

This checks if the array is null or not

if (is_null($result) {
   // do stuf if array is null
} else {
   // do stuf if array is not null
}

I'll assume you mean the URI:

class BankController < ActionController::Base
  before_filter :pre_process 

  def index
    # do something
  end

  private
    def pre_process
      logger.debug("The URL" + request.url)
    end
end

As per your comment below, if you need the name of the controller, you can simply do this:

  private
    def pre_process
      self.controller_name        #  Will return "order"
      self.controller_class_name  # Will return "OrderController"
    end

this is the current Object instance. Whenever you have a non-static method, it can only be called on an instance of your object.

Flat Assembler does not need an extra linker. This makes assembler programming quite easy. It is also available for Linux.

This is hello.asm from the Fasm examples:

include 'win32ax.inc'

.code

  start:
    invoke  MessageBox,HWND_DESKTOP,"Hi! I'm the example program!",invoke GetCommandLine,MB_OK
    invoke  ExitProcess,0

.end start

Fasm creates an executable:

>fasm hello.asm
flat assembler  version 1.70.03  (1048575 kilobytes memory)
4 passes, 1536 bytes.

And this is the program in IDA:

You can see the three calls: GetCommandLine, MessageBox and ExitProcess.

Have a look at the documentation. You made the following mistakes. Firstly, ps.executeQuery() doesn't have any parameters. Instead you passed the SQL query into it.

Secondly, regarding the prepared statement, you have to use the ? symbol if want to pass any parameters. And later bind it using

setXXX(index, value) 

Here xxx stands for the data type.

When You want to open new tab/window (depends on Your browser configuration defaults):

output = 'Hello, World!';
window.open().document.write(output);

When output is an Object and You want get JSON, for example (also can generate any type of document, even image encoded in Base64)

output = ({a:1,b:'2'});
window.open('data:application/json;' + (window.btoa?'base64,'+btoa(JSON.stringify(output)):JSON.stringify(output)));

Update

Google Chrome (60.0.3112.90) block this code:

Not allowed to navigate top frame to data URL: data:application/json;base64,eyJhIjoxLCJiIjoiMiJ9

When You want to append some data to existing page

output = '<h1>Hello, World!</h1>';
window.open('output.html').document.body.innerHTML += output;

output = 'Hello, World!';
window.open('about:blank').document.body.innerText += output;

Is there a step missing?

Yes. You need to create the directory:

mkdir ${HOME}/.ssh

Additionally, SSH requires you to set the permissions so that only you (the owner) can access anything in ~/.ssh:

% chmod 700 ~/.ssh

Should the .ssh dir be generated when I use the ssh-keygen command?

No. This command generates an SSH key pair but will fail if it cannot write to the required directory:

% ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/xxx/.ssh/id_rsa): /Users/tmp/does_not_exist
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
open /Users/tmp/does_not_exist failed: No such file or directory.
Saving the key failed: /Users/tmp/does_not_exist.

Once you've created your keys, you should also restrict who can read those key files to just yourself:

% chmod -R go-wrx ~/.ssh/*

I like to do this witch i think is cleaner :

1 - Add the model to namespace:

use App\Employee;

2 - then you can do :

$employees = Employee::get();

or maybe somthing like this:

$employee = Employee::where('name', 'John')->first();

(trunc(random() * 10) % 10) + 1

Made a sample code implementing the same with slide effects from left, right, top and bottom. (For those who dont want to make all those anim xml files :) )

Checkout out the code on github

You could be lazy, and wrap it in a lambda:

my_hash = YAML.load_file('yml')
my_lamb = lambda { |key| my_hash[key.to_s] }

my_lamb[:a] == my_hash['a'] #=> true

But this would only work for reading from the hash - not writing.

To do that, you could use Hash#merge

my_hash = Hash.new { |h,k| h[k] = h[k.to_s] }.merge(YAML.load_file('yml'))

The init block will convert the keys one time on demand, though if you update the value for the string version of the key after accessing the symbol version, the symbol version won't be updated.

irb> x = { 'a' => 1, 'b' => 2 }
#=> {"a"=>1, "b"=>2}
irb> y = Hash.new { |h,k| h[k] = h[k.to_s] }.merge(x)
#=> {"a"=>1, "b"=>2}
irb> y[:a]  # the key :a doesn't exist for y, so the init block is called
#=> 1
irb> y
#=> {"a"=>1, :a=>1, "b"=>2}
irb> y[:a]  # the key :a now exists for y, so the init block is isn't called
#=> 1
irb> y['a'] = 3
#=> 3
irb> y
#=> {"a"=>3, :a=>1, "b"=>2}

You could also have the init block not update the hash, which would protect you from that kind of error, but you'd still be vulnerable to the opposite - updating the symbol version wouldn't update the string version:

irb> q = { 'c' => 4, 'd' => 5 }
#=> {"c"=>4, "d"=>5}
irb> r = Hash.new { |h,k| h[k.to_s] }.merge(q)
#=> {"c"=>4, "d"=>5}
irb> r[:c] # init block is called
#=> 4
irb> r
#=> {"c"=>4, "d"=>5}
irb> r[:c] # init block is called again, since this key still isn't in r
#=> 4
irb> r[:c] = 7
#=> 7
irb> r
#=> {:c=>7, "c"=>4, "d"=>5}

So the thing to be careful of with these is switching between the two key forms. Stick with one.

In my case after downgrading from .NET 4.5 to .NET 4.0 project was working fine on a local machine, but was failing on server after publishing.

Turns out that destination had some old assemblies, which were still referencing .NET 4.5.

Fixed it by enabling publishing option "Delete all existing files prior to publish"

I am also using mssql server 2008 and jtds.In my case I am using the following connect string and it works.

Class.forName( "net.sourceforge.jtds.jdbc.Driver" );
Connection con = DriverManager.getConnection( "jdbc:jtds:sqlserver://<your server ip     
address>:1433/zacmpf", userName, password );
Statement stmt = con.createStatement();

If you want to set different color for clicked and unclicked radio button just use:

   android:buttonTint="@drawable/radiobutton"  in xml of the radiobutton and your radiobutton.xml will be:  
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:color="#1E88E5"/>
<item android:state_checked="true" android:color="#00e676"/>
<item android:color="#ffffff"/>

Simpler with the ANY construct:

SELECT value_variable = ANY ('{1,2,3}'::int[])

The right operand of ANY (between parentheses) can either be a set (result of a subquery, for instance) or an array. There are several ways to use it:

• SQLAlchemy: how to filter on PgArray column types?
• IN vs ANY operator in PostgreSQL

Important difference: Array operators (<@, @>, && et al.) expect array types as operands and support GIN or GiST indices in the standard distribution of PostgreSQL, while the ANY construct expects an element type as left operand and does not support these indices. Example:

• Index for finding an element in a JSON array

None of this works for NULL elements. To test for NULL:

• Check if NULL exists in Postgres array

I found this solution in "Super useful bits of PHP, Form and JavaScript code" at Skytopia.

Inside "page1.php" or "page1.html":

// Send the variables myNumber=1 and myFruit="orange" to the new PHP page...
<a href="page2c.php?myNumber=1&myFruit=orange">Send variables via URL!</a> 

    //or as I needed it.
    <a href='page2c.php?myNumber={$row[0]}&myFruit={$row[1]}'>Send variables</a>

Inside "page2c.php":

<?php
    // Retrieve the URL variables (using PHP).
    $num = $_GET['myNumber'];
    $fruit = $_GET['myFruit'];
    echo "Number: ".$num."  Fruit: ".$fruit;
?>

Try just clearing the data (not the entire table including headers):

ACell.ListObject.DataBodyRange.ClearContents

String extends Object, which means an Object. Object o = a; If you really want to get as Object, you may do like below.

String s = "Hi";

Object a =s;

This can be achieved by doing

(a2 & a1) == a2

This creates the intersection of both arrays, returning all elements from a2 which are also in a1. If the result is the same as a2, you can be sure you have all elements included in a1.

This approach only works if all elements in a2 are different from each other in the first place. If there are doubles, this approach fails. The one from Tempos still works then, so I wholeheartedly recommend his approach (also it's probably faster).

Nick Craver's comment is the simplest to avoid the error that occurs if the dialog has not yet been defined:

if ($('#elem').is(':visible')) { 
  // do something
}

You should set visibility in your CSS first though, using simply:

#elem { display: none; }

The REST API for Dropbox, Twitter, Google Web Services and Facebook all uses underscores.

Even when the question is regarding Java 7, I think it adds value to know that from Java 11 onward, there is a static method in Path class that allows to do this straight away:

With all the path in one String:

Path.of("/tmp/foo");

With the path broken down in several Strings:

Path.of("/tmp","foo");

For whom are using Spring Boot, you can configure the default behaviour of Jackson by using the Jackson2ObjectMapperBuilder.

For example :

@Bean
public Jackson2ObjectMapperBuilder configureObjectMapper() {
    Jackson2ObjectMapperBuilder oMapper = new Jackson2ObjectMapperBuilder();
    oMapper.failOnUnknownProperties(false);
    return oMapper;
}

Then you can autowire the ObjectMapper everywhere you need it (by default, this object mapper will also be used for http content conversion).

Markdown is just a text file which optionally has .md, or .markdown extensions. It can be converted to HTML. To know syntax of Markdown, Check out

GitHub Flavored Markdown.

You can use any text editor for markdown. If you are sublime text user, you can check out Markdown Preview plugin which will display the rendered markdown content in browser and updates whenever you change the markdown file.

Some of the online markdown editor

• Markable
• dillinger
• markdownviewer

I think the easiest way to solve this issue, if you only need it on 1 or 2 boxes is by using the HTML input's "onsubmit" function.

Check this out and i will explain what it does:

<input type="text" name="val" onsubmit="if(this == ''){$this.val('empty');}" />

So we have created the HTML text box, assigned it a name ("val" in this case) and then we added the onsubmit code, this code checks to see if the current input box is empty and if it is, then, upon form submit it will fill it with the words empty.

Please note, this code should also function perfectly when using the HTML "Placeholder" tag as the placeholder tag doesn't actually assign a value to the input box.

I think the best way to implement enumeration like types is with symbols since the pretty much behave as integer (when it comes to performace, object_id is used to make comparisons ); you don't need to worry about indexing and they look really neat in your code xD

UPDATE (GEOCODE MULTIPLE ADDRESSES)

Here's the working Example Geocoding with multiple addresses.

 <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false">

  var mapOptions = {
    zoom: 5,
    center: latlng,
    mapTypeId: google.maps.MapTypeId.ROADMAP
  }
  var geocoder = new google.maps.Geocoder(); 
  var map = new google.maps.Map(document.getElementById("map"), mapOptions);
  var bounds = new google.maps.LatLngBounds();

  function geocodeAddress(address, next) {
    geocoder.geocode({address:address}, function (results,status)
      { 
         if (status == google.maps.GeocoderStatus.OK) {
          var p = results[0].geometry.location;
          var lat=p.lat();
          var lng=p.lng();
          createMarker(address,lat,lng);
        }
        else {
           if (status == google.maps.GeocoderStatus.OVER_QUERY_LIMIT) {
            nextAddress--;
            delay++;
          } else {
                        }   
        }
        next();
      }
    );
  }
 function createMarker(add,lat,lng) {
   var contentString = add;
   var marker = new google.maps.Marker({
     position: new google.maps.LatLng(lat,lng),
     map: map,
           });

  google.maps.event.addListener(marker, 'click', function() {
     infowindow.setContent(contentString); 
     infowindow.open(map,marker);
   });

   bounds.extend(marker.position);

 }
  var locations = [
           'New Delhi, India',
           'Mumbai, India',
           'Bangaluru, Karnataka, India',
           'Hyderabad, Ahemdabad, India',
           'Gurgaon, Haryana, India',
           'Cannaught Place, New Delhi, India',
           'Bandra, Mumbai, India',
           'Nainital, Uttranchal, India',
           'Guwahati, India',
           'West Bengal, India',
           'Jammu, India',

  ];
  var nextAddress = 0;
  function theNext() {
    if (nextAddress < locations.length) {
      setTimeout('geocodeAddress("'+locations[nextAddress]+'",theNext)', delay);
      nextAddress++;
    } else {
      map.fitBounds(bounds);
    }
  }
  theNext();

</script>

As we can resolve this issue with setTimeout() function.

Still we should not geocode known locations every time you load your page as said by @geocodezip

Another alternatives of these are explained very well in the following links:

Provide a module whose responsibility is to execute requests sequentially, while tracking the current index of each operation in an ordinal manner. Define the operation in a Command Pattern for flexibility.

Participants

• Context: The object whose member method performs an operation.
• SequentialPromise: Defines an execute method to chain & track each operation. SequentialPromise returns a Promise-Chain from all operations performed.
• Invoker: Creates a SequentialPromise instance, providing it context & action, and calls its execute method while passing in an ordinal list of options for each operation.

Consequences

Use SequentialPromise when ordinal behavior of Promise resolution is needed. SequentialPromise will track the index for which a Promise was rejected.

Implementation

clear();

var http = {
    get(url) {
        var delay = Math.floor( Math.random() * 10 ), even = !(delay % 2);
        var xhr = new Promise(exe);

        console.log(`REQUEST`, url, delay);
        xhr.then( (data) => console.log(`SUCCESS: `, data) ).catch( (data) => console.log(`FAILURE: `, data) );

        function exe(resolve, reject) {
            var action = { 'true': reject, 'false': resolve }[ even ];
            setTimeout( () => action({ url, delay }), (1000 * delay) );
        }

        return xhr;
    }
};

var SequentialPromise = new (function SequentialPromise() {
    var PRIVATE = this;

    return class SequentialPromise {

        constructor(context, action) {
            this.index = 0;
            this.requests = [ ];
            this.context = context;
            this.action = action;

            return this;
        }

        log() {}

        execute(url, ...more) {
            var { context, action, requests } = this;
            var chain = context[action](url);

            requests.push(chain);
            chain.then( (data) => this.index += 1 );

            if (more.length) return chain.then( () => this.execute(...more) );
            return chain;
        }

    };
})();

var sequence = new SequentialPromise(http, 'get');
var urls = [
    'url/name/space/0',
    'url/name/space/1',
    'url/name/space/2',
    'url/name/space/3',
    'url/name/space/4',
    'url/name/space/5',
    'url/name/space/6',
    'url/name/space/7',
    'url/name/space/8',
    'url/name/space/9'
];
var chain = sequence.execute(...urls);
var promises = sequence.requests;

chain.catch( () => console.warn(`EXECUTION STOPPED at ${sequence.index} for ${urls[sequence.index]}`) );

// console.log('>', chain, promises);

The easiest way was to (prior to Java 8) use,

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");

But SimpleDateFormat is not thread-safe. Neither java.util.Date. This will lead to leading to potential concurrency issues for users. And there are many problems in those existing designs. To overcome these now in Java 8 we have a separate package called java.time. This Java SE 8 Date and Time document has a good overview about it.

So in Java 8 something like below will do the trick (to format the current date/time),

LocalDateTime.now()
   .format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS"));

And one thing to note is it was developed with the help of the popular third party library joda-time,

The project has been led jointly by the author of Joda-Time (Stephen Colebourne) and Oracle, under JSR 310, and will appear in the new Java SE 8 package java.time.

But now the joda-time is becoming deprecated and asked the users to migrate to new java.time.

Note that from Java SE 8 onwards, users are asked to migrate to java.time (JSR-310) - a core part of the JDK which replaces this project

Anyway having said that,

If you have a Calendar instance you can use below to convert it to the new java.time,

    Calendar calendar = Calendar.getInstance();
    long longValue = calendar.getTimeInMillis();         

    LocalDateTime date =
            LocalDateTime.ofInstant(Instant.ofEpochMilli(longValue), ZoneId.systemDefault());
    String formattedString = date.format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS"));

    System.out.println(date.toString()); // 2018-03-06T15:56:53.634
    System.out.println(formattedString); // 2018-03-06 15:56:53.634

If you had a Date object,

    Date date = new Date();
    long longValue2 = date.getTime();

    LocalDateTime dateTime =
            LocalDateTime.ofInstant(Instant.ofEpochMilli(longValue2), ZoneId.systemDefault());
    String formattedString = dateTime.format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS"));

    System.out.println(dateTime.toString()); // 2018-03-06T15:59:30.278
    System.out.println(formattedString);     // 2018-03-06 15:59:30.278

If you just had the epoch milliseconds,

LocalDateTime date =
        LocalDateTime.ofInstant(Instant.ofEpochMilli(epochLongValue), ZoneId.systemDefault());

declare @x varchar(20),@y varchar(20)
select @x='sam'
select 
case when @x is null then @y
      when @y is null then @x
      else @x+','+@y
end


go

declare @x varchar(20),@y varchar(20)
select @x='sam'
--,@y='john'
DECLARE @listStr VARCHAR(MAX)   

SELECT @listStr = COALESCE(@x + ', ' ,'') +coalesce(@y+',','')
SELECT left(@listStr,len(@listStr)-1)

you can try this

td.setAttribute("style", "font-weight:bold");

public class TypedProperty<T> : Property
{
    public T TypedValue
    {
        get { return (T)(object)base.Value; }
        set { base.Value = value.ToString();}
    }
}

I using converting via an object. It is a little bit simpler.

Command-line arguments are passed in the first String[] parameter to main(), e.g.

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

In the example above, args contains all the command-line arguments.

The short, sweet answer to the question posed is:

public static void main( String[] args ) {
    if( args.length > 0 && args[0].equals( "a" ) ) {
        // first argument is "a"
    } else {
        // oh noes!?
    }
}

In my case, I was using wrong linking.
It was managed c++ (cli) but with native exporting. I have added to linker -> input -> assembly link resource the dll of the library from which the function is exported. But native c++ linking requires .lib file to "see" implementations in cpp correctly, so for me helped to add the .lib file to linker -> input -> additional dependencies.
[Usually managed code does not use dll export and import, it uses references, but that was unique situation.]

In MVC 4 If you want maxlenght in input type text ? You can !

@Html.TextBoxFor(model => model.Item3.ADR_ZIP, new { @class = "gui-input ui-oblig", @maxlength = "5" })

What you are looking for is called Model persistence in sklearn words and it is documented in introduction and in model persistence sections.

So you have initialized your classifier and trained it for a long time with

clf = some.classifier()
clf.fit(X, y)

After this you have two options:

1) Using Pickle

import pickle
# now you can save it to a file
with open('filename.pkl', 'wb') as f:
    pickle.dump(clf, f)

# and later you can load it
with open('filename.pkl', 'rb') as f:
    clf = pickle.load(f)

2) Using Joblib

from sklearn.externals import joblib
# now you can save it to a file
joblib.dump(clf, 'filename.pkl') 
# and later you can load it
clf = joblib.load('filename.pkl')

One more time it is helpful to read the above-mentioned links

Just create new package and move Classes to created package.

(default package) means that is no package.

In any web application, there will be a web.xml in the WEB-INF/ folder.

If you dont have one in your web app, as it seems to be the case in your folder structure, the default Tomcat web.xml is under TOMCAT_HOME/conf/web.xml

Either way, the relevant lines of the web.xml are

<welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

so any file matching this pattern when found will be shown as the home page.

In Tomcat, a web.xml setting within your web app will override the default, if present.

For route controller method we have to define only one route. In get or post method we have to define the route separately.

And the resources method is used to creates multiple routes to handle a variety of Restful actions.

Here the Laravel documentation about this.

You could also just put the first SELECT in a subquery. Since most optimizers will fold it into a constant anyway, there should not be a performance hit on this.

Incidentally, since you are using a predicate like this:

CONVERT(...) = CONVERT(...)

that predicate expression cannot be optimized properly or use indexes on the columns reference by the CONVERT() function.

Here is one way to make the original query somewhat better:

DECLARE @ooDate datetime
SELECT @ooDate = OO.Date FROM OLAP.OutageHours AS OO where OO.OutageID = 1

SELECT 
  COUNT(FF.HALID)
FROM
  Outages.FaultsInOutages AS OFIO 
  INNER JOIN Faults.Faults as FF ON 
    FF.HALID = OFIO.HALID 
WHERE
  FF.FaultDate >= @ooDate AND
  FF.FaultDate < DATEADD(day, 1, @ooDate) AND
  OFIO.OutageID = 1

This version could leverage in index that involved FaultDate, and achieves the same goal.

Here it is, rewritten to use a subquery to avoid the variable declaration and subsequent SELECT.

SELECT 
  COUNT(FF.HALID)
FROM
  Outages.FaultsInOutages AS OFIO 
  INNER JOIN Faults.Faults as FF ON 
    FF.HALID = OFIO.HALID 
WHERE
  CONVERT(varchar(10), FF.FaultDate, 126) = (SELECT CONVERT(varchar(10), OO.Date, 126) FROM OLAP.OutageHours AS OO where OO.OutageID = 1) AND
  OFIO.OutageID = 1

Note that this approach has the same index usage issue as the original, because of the use of CONVERT() on FF.FaultDate. This could be remedied by adding the subquery twice, but you would be better served with the variable approach in this case. This last version is only for demonstration.

Regards.

If X and beta do not have the same shape as the second term in the rhs of your last line (i.e. nsample), then you will get this type of error. To add an array to a tuple of arrays, they all must be the same shape.

I would recommend looking at the numpy broadcasting rules.

Types are dependent to your initialization:

var IsLoggedIn1 = "true"; //string
var IsLoggedIn2 = 1; //integer
var IsLoggedIn3 = true; //bool

But take a look at this example:

var IsLoggedIn1 = "true"; //string
IsLoggedIn1 = true; //now your variable is a boolean

Your variables' type depends on the assigned value in JavaScript.

exec sp_helptext 'your_sp_name' -- don't forget the quotes

In management studio by default results come in grid view. If you would like to see it in text view go to:

Query --> Results to --> Results to Text

or CTRL + T and then Execute.

We cant connect to iPhones normally by bluetooth.it is so difficult.so,please try any other file transfers like zapya,xender.it seems good

Best aproach for me was:

  private void grid_receptie_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
    {
        int X = 1;
        foreach(DataGridViewRow row in grid_receptie.Rows)
        {
            row.Cells["NR_CRT"].Value = X;
            X++;
        }
    }

Use this one :

 onSelect: function(dateText) {
                 $("input#DateTo").datepicker('option', 'minDate', dateText);
            }

Mock is a method/object that simulates the behavior of a real method/object in controlled ways. Mock objects are used in unit testing.

Often a method under a test calls other external services or methods within it. These are called dependencies. Once mocked, the dependencies behave the way we defined them.

With the dependencies being controlled by mocks, we can easily test the behavior of the method that we coded. This is Unit testing.

What is the purpose of mock objects?

Mocks vs stubs

Unit tests vs Functional tests

You can solve this problem by following two ways:
A) Start your WAMP befor you login to skype. So that WAMP will take over the the port and there will be no conflict with the port number. And you are able to use Skype as well as WAMP.
But this is not the permanent solution for your problem. Whenever you want to start WAMP you need to signout Skype first and than only you are able to start WAMP. Which is really i don’t like.

B) Second option is to change the port of Skype itself, so that it will not conflict with WAMP. Following screen/steps will help you to solve this problem:
1) SignIn to Skype.
2) Got to the Tools -> options
3) Select the “Advanced” -> Connection
4) Unchecked “Use port 80 and 443 as alternatives for incoming connections” checkbox and click save.
5) Now Signout and SignIn again to skype. (this change will take affect only you relogin to skype)
Now every time you start WAMP will not conflict with skype.

Instead of rolling your own, simply use what's provided for you.

As mentioned previously, do not disable caching for everything. For instance, jQuery scripts used heavily in ASP.NET MVC should be cached. Actually ideally you should be using a CDN for those anyway, but my point is some content should be cached.

What I find works best here rather than sprinkling the [OutputCache] everywhere is to use a class:

[System.Web.Mvc.OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")]
public class NoCacheController  : Controller
{
}

All of your controllers you want to disable caching for then inherit from this controller.

If you need to override the defaults in the NoCacheController class, simply specify the cache settings on your action method and the settings on your Action method will take precedence.

[HttpGet]
[OutputCache(NoStore = true, Duration = 60, VaryByParam = "*")]
public ViewResult Index()
{
  ...
}

Hmm..I did this right now by just downloading Python 3.6.5 for Windows at https://www.python.org/downloads/release/python-365/ and made sure that the launcher would be installed. Then, I followed the instructions for using python 2 and python 3. Restart the command prompt and then use py -2.7 to use Python 2 and py or py -3.6 to use Python 3. You can also use pip2 for Python 2's pip and pip for Python 3's pip.

for (StackTraceElement ste : Thread.currentThread().getStackTrace()) {
    System.out.println(ste);
}

assuming both elements have 50% width, here is what i used:

css:

  .parent {
    width: 100%;
    display: flex;
  }  
  .child-1 {
    width: 50%;
    margin-right: -50%;
    margin-left: 50%;
    background: #ff0;
  }
  .child-2 {
    width: 50%;
    margin-right: 50%;
    margin-left: -50%;
    background: #0f0;
  }

html:

<div class="parent">
  <div class="child-1">child1</div>
  <div class="child-2">child2</div>
</div>

example: https://jsfiddle.net/gzveri/o6umhj53/

btw, this approach works for any 2 nearby elements in a long list of elements. For example I have a long list of elements with 2 items per row and I want each 3-rd and 4-th element in the list to be swapped, so that it renders elements in a chess style, then I use these rules:

  .parent > div:nth-child(4n+3) {
    margin-right: -50%;
    margin-left: 50%;
  }
  .parent > div:nth-child(4n+4) {
    margin-right: 50%;
    margin-left: -50%;
  }

If you are using Oracle Database then you can achieve this using contains query. Contains querys are faster than like query.

If you need all of the words

SELECT * FROM MyTable WHERE CONTAINS(Column1,'word1 and word2 and word3', 1) > 0

If you need any of the words

SELECT * FROM MyTable WHERE CONTAINS(Column1,'word1 or word2 or word3', 1) > 0

Contains need index of type CONTEXT on your column.

CREATE INDEX SEARCH_IDX ON MyTable(Column) INDEXTYPE IS CTXSYS.CONTEXT

you define the struct as xyx but you're trying to create the struct called xyz.

UPDATED for clarification and example

examples: http://jsfiddle.net/pxfunc/5kpeJ/

Method 1. input event

In modern browsers use the input event. This event will fire when the user is typing into a text field, pasting, undoing, basically anytime the value changed from one value to another.

In jQuery do that like this

$('#someInput').bind('input', function() { 
    $(this).val() // get the current value of the input field.
});

starting with jQuery 1.7, replace bind with on:

$('#someInput').on('input', function() { 
    $(this).val() // get the current value of the input field.
});

Method 2. keyup event

For older browsers use the keyup event (this will fire once a key on the keyboard has been released, this event can give a sort of false positive because when "w" is released the input value is changed and the keyup event fires, but also when the "shift" key is released the keyup event fires but no change has been made to the input.). Also this method doesn't fire if the user right-clicks and pastes from the context menu:

$('#someInput').keyup(function() {
    $(this).val() // get the current value of the input field.
});

Method 3. Timer (setInterval or setTimeout)

To get around the limitations of keyup you can set a timer to periodically check the value of the input to determine a change in value. You can use setInterval or setTimeout to do this timer check. See the marked answer on this SO question: jQuery textbox change event or see the fiddle for a working example using focus and blur events to start and stop the timer for a specific input field

I don't know if this is only in the recent versions, but right clicking on the Tables option in the Navigator pane pops up an option called Search Table Data. This opens up a search box where you fill in the search string and hit search.

You do need to select the table you want to search in on the left pane. But if you hold down shift and select like 10 tables at a time, MySql can handle that and return results in seconds.

For anyone that is looking for better options! :)

This post is old, but I change your code to:

scope.$watch("assignments", function (value) {//I change here
  var val = value || null;            
  if (val)
    element.dataTable({"bDestroy": true});
  });
}

see jsfiddle.

I hope it helps you

I have done it two different ways,

1.) make a Map

        HashMap<String, String> applicationSettings = new HashMap<String,String>();
        for(int i=0; i<settings.length(); i++){
            String value = settings.getJSONObject(i).getString("value");
            String name = settings.getJSONObject(i).getString("name");
            applicationSettings.put(name, value);
        }

2.) make a JSONArray of names

    JSONArray names = json.names();
    JSONArray values = json.toJSONArray(names);
    for(int i=0; i<values.length(); i++){
        if (names.getString(i).equals("description")){
            setDescription(values.getString(i));
        }
        else if (names.getString(i).equals("expiryDate")){
            String dateString = values.getString(i);
            setExpiryDate(stringToDateHelper(dateString)); 
        }
        else if (names.getString(i).equals("id")){
            setId(values.getLong(i));
        }
        else if (names.getString(i).equals("offerCode")){
            setOfferCode(values.getString(i));
        }
        else if (names.getString(i).equals("startDate")){
            String dateString = values.getString(i);
            setStartDate(stringToDateHelper(dateString));
        }
        else if (names.getString(i).equals("title")){
            setTitle(values.getString(i));
        }
    }

In my case an additional file not belonging to the database was inside the database folder. Mysql found the folder not empty after dropping all tables which triggered the error. I remove the file and the drop database worked fine.

You are using Python 2 for which the input() function tries to evaluate the expression entered. Because you enter a string, Python treats it as a name and tries to evaluate it. If there is no variable defined with that name you will get a NameError exception.

To fix the problem, in Python 2, you can use raw_input(). This returns the string entered by the user and does not attempt to evaluate it.

Note that if you were using Python 3, input() behaves the same as raw_input() does in Python 2.

In your script, why are you using single quotes around the variables? These will not be expanded. Use double quotes for variable expansion or just the variable names themselves.

unzipRelease –Src '$ReleaseFile' -Dst '$Destination'

to

unzipRelease –Src "$ReleaseFile" -Dst "$Destination"

In VB code, when trying to submit an INSERT query, you must submit a double query in the same 'executenonquery' like this:

sqlQuery = "SET IDENTITY_INSERT dbo.TheTable ON; INSERT INTO dbo.TheTable (Col1, COl2) VALUES (Val1, Val2); SET IDENTITY_INSERT dbo.TheTable OFF;"

I used a ; separator instead of a GO.

Works for me. Late but efficient!

You can provide padding to an input like this:

HTML:

<input type=text id=firstname />

CSS:

input {
    width: 250px;
    padding: 5px;
}

however I would also add:

input {
    width: 250px;
    padding: 5px;
    -webkit-box-sizing: border-box; /* Safari/Chrome, other WebKit */
    -moz-box-sizing: border-box;    /* Firefox, other Gecko */
    box-sizing: border-box;         /* Opera/IE 8+ */
}

Box sizing makes the input width stay at 250px rather than increase to 260px due to the padding.

For reference.

For those searching for a solution to the issue of the ripple effect not working on a programmatically created CardView (or in my case custom view which extends CardView) being shown in a RecyclerView, the following worked for me. Basically declaring the XML attributes mentioned in the other answers declaratively in the XML layout file doesn't seem to work for a programmatically created CardView, or one created from a custom layout (even if root view is CardView or merge element is used), so they have to be set programmatically like so:

private class MadeUpCardViewHolder extends RecyclerView.ViewHolder {
    private MadeUpCardView cardView;

    public MadeUpCardViewHolder(View v){
        super(v);

        this.cardView = (MadeUpCardView)v;

        // Declaring in XML Layout doesn't seem to work in RecyclerViews
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            int[] attrs = new int[]{R.attr.selectableItemBackground};
            TypedArray typedArray = context.obtainStyledAttributes(attrs);
            int selectableItemBackground = typedArray.getResourceId(0, 0);
            typedArray.recycle();

            this.cardView.setForeground(context.getDrawable(selectableItemBackground));
            this.cardView.setClickable(true);
        }
    }
}

Where MadeupCardView extends CardView Kudos to this answer for the TypedArray part.

You can use SVGKit for example.

1) Integrate it according to instructions. Drag&dropping the .framework file is fast and easy.

2) Make sure you have an Objective-C to Swift bridge file bridging-header.h with import code in it:

#import <SVGKit/SVGKit.h>
#import <SVGKit/SVGKImage.h>

3) Use the framework like this, assuming that dataFromInternet is NSData, previously downloaded from network:

let anSVGImage: SVGKImage = SVGKImage(data: dataFromInternet)
myIUImageView.image = anSVGImage.UIImage

The framework also allows to init an SVGKImage from other different sources, for example it can download image for you when you provide it with URL. But in my case it was crashing in case of unreachable url, so it turned out to be better to manage networking by myself. More info on it here.

You can use process monitor written by Mark Russinovich. This is a fantastic little application that will allow you to attach to any running process on the system and see all of the system calls that process is currently making.

    res.send('Hello World!')

I had the same problem, but I didn't want to change to PTP mode. This is how I fixed it with MTP still enabled.

1. Uninstalled Google USB Driver from Eclipse in the Android SDK Manager.
2. Uninstalled the driver from Device Manager - click box for "delete driver from my computer"
3. Unplugged and re-plugged my phone into the computer.
4. Windows "improperly" installed drivers for the Nexus 4.
5. The Nexus 4 was now showing up in My Computer like a drive.
6. Reinstall Google USB Driver in SDK Manager.
7. Update Nexus 4 driver in Device Manager.
8. Everything works.

As your intuition correctly guessed, the naive solution with a pair of exists / writeFile calls is wrong. Asynchronous code runs in unpredictable ways. And in given case it is

• Is there a file a.txt? — No.
• (File a.txt gets created by another program)
• Write to a.txt if it's possible. — Okay.

But yes, we can do that in a single call. We're working with file system so it's a good idea to read developer manual on fs. And hey, here's an interesting part.

'w' - Open file for writing. The file is created (if it does not exist) or truncated (if it exists).

'wx' - Like 'w' but fails if path exists.

So all we have to do is just add wx to the fs.open call. But hey, we don't like fopen-like IO. Let's read on fs.writeFile a bit more.

fs.readFile(filename[, options], callback)#

filename String

options Object

encoding String | Null default = null

flag String default = 'r'

callback Function

That options.flag looks promising. So we try

fs.writeFile(path, data, { flag: 'wx' }, function (err) {
    if (err) throw err;
    console.log("It's saved!");
});

And it works perfectly for a single write. I guess this code will fail in some more bizarre ways yet if you try to solve your task with it. You have an atomary "check for a_#.jpg existence, and write there if it's empty" operation, but all the other fs state is not locked, and a_1.jpg file may spontaneously disappear while you're already checking a_5.jpg. Most* file systems are no ACID databases, and the fact that you're able to do at least some atomic operations is miraculous. It's very likely that wx code won't work on some platform. So for the sake of your sanity, use database, finally.

Some more info for the suffering

Imagine we're writing something like memoize-fs that caches results of function calls to the file system to save us some network/cpu time. Could we open the file for reading if it exists, and for writing if it doesn't, all in the single call? Let's take a funny look on those flags. After a while of mental exercises we can see that a+ does what we want: if the file doesn't exist, it creates one and opens it both for reading and writing, and if the file exists it does so without clearing the file (as w+ would). But now we cannot use it neither in (smth)File, nor in create(Smth)Stream functions. And that seems like a missing feature.

So feel free to file it as a feature request (or even a bug) to Node.js github, as lack of atomic asynchronous file system API is a drawback of Node. Though don't expect changes any time soon.

Edit. I would like to link to articles by Linus and by Dan Luu on why exactly you don't want to do anything smart with your fs calls, because the claim was left mostly not based on anything.

use the nextSibling and previousSibling properties:

<div id="foo1"></div>
<div id="foo2"></div>
<div id="foo3"></div>

document.getElementById('foo2').nextSibling; // #foo3
document.getElementById('foo2').previousSibling; // #foo1

However in some browsers (I forget which) you also need to check for whitespace and comment nodes:

var div = document.getElementById('foo2');
var nextSibling = div.nextSibling;
while(nextSibling && nextSibling.nodeType != 1) {
    nextSibling = nextSibling.nextSibling
}

Libraries like jQuery handle all these cross-browser checks for you out of the box.

I faced this issue when I imported a two project in the workspace. It created a different jar somehow so we can delete the jars and the class files and build the project again to get the dependencies right.

Paul Irish has a way to do this that covers most of the common problems. See his bullet-proof @font-face article:

The final variant, which stops unnecessary data from being downloaded by IE, and works in IE8, Firefox, Opera, Safari, and Chrome looks like this:

@font-face {
  font-family: 'Graublau Web';
  src: url('GraublauWeb.eot');
  src: local('Graublau Web Regular'), local('Graublau Web'),
    url("GraublauWeb.woff") format("woff"),
    url("GraublauWeb.otf") format("opentype"),
    url("GraublauWeb.svg#grablau") format("svg");
}

He also links to a generator that will translate the fonts into all the formats you need.

As others have already specified, this will only work in the latest generation of browsers. Your best bet is to use this in conjunction with something like Cufon, and only load Cufon if the browser doesn't support @font-face.

According to the Wordpress documentation, you should use wp_localize_script() in your functions.php file. This will create a Javascript Object in the header, which will be available to your scripts at runtime.

See Codex

Example:

<?php wp_localize_script('mylib', 'WPURLS', array( 'siteurl' => get_option('siteurl') )); ?>

To access this variable within in Javascript, you would simply do:

<script type="text/javascript">
    var url = WPURLS.siteurl;
</script>

How about this other solution to keep the nice switch instead of an if-else:

private enum LayoutElement {
    NONE(-1),
    PLAY_BUTTON(R.id.playbtn),
    STOP_BUTTON(R.id.stopbtn),
    MENU_BUTTON(R.id.btnmenu);

    private static class _ {
        static SparseArray<LayoutElement> elements = new SparseArray<LayoutElement>();
    }

    LayoutElement(int id) {
        _.elements.put(id, this);
    }

    public static LayoutElement from(View view) {
        return _.elements.get(view.getId(), NONE);
    }

}

So in your code you can do this:

public void onClick(View src) {
    switch(LayoutElement.from(src)) {
    case PLAY_BUTTTON:
        checkwificonnection();
        break;

    case STOP_BUTTON:
        Log.d(TAG, "onClick: stopping srvice");
        Playbutton.setImageResource(R.drawable.playbtn1);
        Playbutton.setVisibility(0); //visible
        Stopbutton.setVisibility(4); //invisible
        stopService(new Intent(RakistaRadio.this,myservice.class));
        clearstatusbar();
        timer.cancel();
        Title.setText(" ");
        Artist.setText(" ");
        break;

    case MENU_BUTTON:
        openOptionsMenu();
        break;
    }
}

Enums are static so this will have very limited impact. The only window for concern would be the double lookup involved (first on the internal SparseArray and later on the switch table)

That said, this enum can also be utilised to fetch the items in a fluent manner, if needed by keeping a reference to the id... but that's a story for some other time.

Its work perfectly

ALTER TABLE `products` ADD `LastUpdate` varchar(200) NULL;

But if you want more precise in table then you can try AFTER.

ALTER TABLE `products` ADD `LastUpdate` varchar(200) NULL AFTER `column_name`;

It will add LastUpdate column after specified column name (column_name).

for( int i = 1; i * i <= num; i++ )
{
/* upto sqrt is because every divisor after sqrt
    is also found when the number is divided by i.
   EXAMPLE like if number is 90 when it is divided by 5
    then you can also see that 90/5 = 18
    where 18 also divides the number.
   But when number is a perfect square
    then num / i == i therefore only i is the factor
