UTF-8 is not a character set, it's an encoding. The character set for UTF-8 is Unicode. If you want to store Unicode text you use the nvarchar data type.

If the database would use UTF-8 to store text, you would still not get the text out as encoded UTF-8 data, you would get it out as decoded text.

You can easily store UTF-8 encoded text in the database, but then you don't store it as text, you store it as binary data (varbinary).

using uncontrolled fields:

export default class MyComponent extends React.Component {

    onSubmit(e) {
        e.preventDefault();
        console.log(e.target.neededField.value);
    }

    render(){
        return (
            ...
            <form onSubmit={this.onSubmit} className="form-horizontal">
                ...
                <input type="text" name="neededField" className="form-control" ref={(c) => this.title = c} name="title" />
                ...
            </form>
            ...
            <button type="button" className="btn">Save</button>
            ...
        );
    }

};

Using a ScaleGestureDetector

When learning a new concept I don't like using libraries or code dumps. I found a good description here and in the documentation of how to resize an image by pinching. This answer is a slightly modified summary. You will probably want to add more functionality later, but it will help you get started.

Layout

The ImageView just uses the app logo since it is already available. You can replace it with any image you like, though.

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

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@mipmap/ic_launcher"
        android:layout_centerInParent="true"/>

</RelativeLayout>

Activity

We use a ScaleGestureDetector on the activity to listen to touch events. When a scale (ie, pinch) gesture is detected, then the scale factor is used to resize the ImageView.

public class MainActivity extends AppCompatActivity {

    private ScaleGestureDetector mScaleGestureDetector;
    private float mScaleFactor = 1.0f;
    private ImageView mImageView;

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

        // initialize the view and the gesture detector
        mImageView = findViewById(R.id.imageView);
        mScaleGestureDetector = new ScaleGestureDetector(this, new ScaleListener());
    }

    // this redirects all touch events in the activity to the gesture detector
    @Override
    public boolean onTouchEvent(MotionEvent event) {
        return mScaleGestureDetector.onTouchEvent(event);
    }

    private class ScaleListener extends ScaleGestureDetector.SimpleOnScaleGestureListener {

        // when a scale gesture is detected, use it to resize the image
        @Override
        public boolean onScale(ScaleGestureDetector scaleGestureDetector){
            mScaleFactor *= scaleGestureDetector.getScaleFactor();
            mImageView.setScaleX(mScaleFactor);
            mImageView.setScaleY(mScaleFactor);
            return true;
        }
    }
}

Notes

• Although the activity had the gesture detector in the example above, it could have also been set on the image view itself.

• You can limit the size of the scaling with something like

  mScaleFactor = Math.max(0.1f, Math.min(mScaleFactor, 5.0f));
  

• Thanks again to Pinch-to-zoom with multi-touch gestures In Android

• Documentation
• Use Ctrl + mouse drag to simulate a pinch gesture in the emulator.

Going on

You will probably want to do other things like panning and scaling to some focus point. You can develop these things yourself, but if you would like to use a pre-made custom view, copy TouchImageView.java into your project and use it like a normal ImageView. It worked well for me and I only ran into one bug. I plan to further edit the code to remove the warning and the parts that I don't need. You can do the same.

tl;dr - TWBSColor - Generate your own Bootstrap navbar

Version notes: - Online tool: Bootstrap 3.3.2+ / 4.0.0+ - This answer: Bootstrap 3.0.x

Available navbars

You've got two basic navbars:

<!-- A light one -->
<nav class="navbar navbar-default" role="navigation"></nav>
<!-- A dark one -->
<nav class="navbar navbar-inverse" role="navigation"></nav>

Default color usage

Here are the main colors and their usage:

• #F8F8F8: navbar background
• #E7E7E7: navbar border
• #777: default color
• #333: hover color (#5E5E5E for .nav-brand)
• #555: active color
• #D5D5D5: active background

Default style

If you want to put some custom style, here's the CSS you need to change:

/* navbar */
.navbar-default {
    background-color: #F8F8F8;
    border-color: #E7E7E7;
}
/* Title */
.navbar-default .navbar-brand {
    color: #777;
}
.navbar-default .navbar-brand:hover,
.navbar-default .navbar-brand:focus {
    color: #5E5E5E;
}
/* Link */
.navbar-default .navbar-nav > li > a {
    color: #777;
}
.navbar-default .navbar-nav > li > a:hover,
.navbar-default .navbar-nav > li > a:focus {
    color: #333;
}
.navbar-default .navbar-nav > .active > a,
.navbar-default .navbar-nav > .active > a:hover,
.navbar-default .navbar-nav > .active > a:focus {
    color: #555;
    background-color: #E7E7E7;
}
.navbar-default .navbar-nav > .open > a,
.navbar-default .navbar-nav > .open > a:hover,
.navbar-default .navbar-nav > .open > a:focus {
    color: #555;
    background-color: #D5D5D5;
}
/* Caret */
.navbar-default .navbar-nav > .dropdown > a .caret {
    border-top-color: #777;
    border-bottom-color: #777;
}
.navbar-default .navbar-nav > .dropdown > a:hover .caret,
.navbar-default .navbar-nav > .dropdown > a:focus .caret {
    border-top-color: #333;
    border-bottom-color: #333;
}
.navbar-default .navbar-nav > .open > a .caret,
.navbar-default .navbar-nav > .open > a:hover .caret,
.navbar-default .navbar-nav > .open > a:focus .caret {
    border-top-color: #555;
    border-bottom-color: #555;
}
/* Mobile version */
.navbar-default .navbar-toggle {
    border-color: #DDD;
}
.navbar-default .navbar-toggle:hover,
.navbar-default .navbar-toggle:focus {
    background-color: #DDD;
}
.navbar-default .navbar-toggle .icon-bar {
    background-color: #CCC;
}
@media (max-width: 767px) {
    .navbar-default .navbar-nav .open .dropdown-menu > li > a {
        color: #777;
    }
    .navbar-default .navbar-nav .open .dropdown-menu > li > a:hover,
    .navbar-default .navbar-nav .open .dropdown-menu > li > a:focus {
          color: #333;
    }
}

Custom colored navbar examples

Here are four examples of a custom colored navbar:

And the SCSS code:

$bgDefault   : #e74c3c;
$bgHighlight : #c0392b;
$colDefault  : #ecf0f1;
$colHighlight: #ffbbbc;
.navbar-default {
  background-color: $bgDefault;
  border-color: $bgHighlight;
  .navbar-brand {
    color: $colDefault;
    &:hover, &:focus {
      color: $colHighlight; }}
  .navbar-text {
    color: $colDefault; }
  .navbar-nav {
    > li {
      > a {
        color: $colDefault;
        &:hover,  &:focus {
          color: $colHighlight; }}}
    > .active {
      > a, > a:hover, > a:focus {
        color: $colHighlight;
        background-color: $bgHighlight; }}
    > .open {
      > a, > a:hover, > a:focus {
        color: $colHighlight;
        background-color: $bgHighlight; }}}
  .navbar-toggle {
    border-color: $bgHighlight;
    &:hover, &:focus {
      background-color: $bgHighlight; }
    .icon-bar {
      background-color: $colDefault; }}
  .navbar-collapse,
  .navbar-form {
    border-color: $colDefault; }
  .navbar-link {
    color: $colDefault;
    &:hover {
      color: $colHighlight; }}}
@media (max-width: 767px) {
  .navbar-default .navbar-nav .open .dropdown-menu {
    > li > a {
      color: $colDefault;
      &:hover, &:focus {
        color: $colHighlight; }}
    > .active {
      > a, > a:hover, > a:focus, {
        color: $colHighlight;
        background-color: $bgHighlight; }}}
}

And finally, a little gift

I've just made a script which will allow you to generate your theme: TWBSColor - Generate your own Bootstrap navbar

[Update]: TWBSColor now generates SCSS/SASS/Less/CSS code.
[Update]: From now, you can use Less as the default language provided by TWBSColor
[Update]: TWBSColor now supports drop down menus colorization
[Update]: TWBSColor now allows to choose your version (Bootstrap 4 support added)

You can use the status command in MySQL client.

<button id="OpenImgUpload" onclick="$('#imgupload').trigger('click');">Image Upload</button>
<input type="file" id="imgupload" style="display:none"/> 

A slight variant of Matthew Dowell's post which avoids the short flash, but displays whenever the contact form 7 form is visible:

div.grecaptcha-badge{
    width:0 !important;
}

div.grecaptcha-badge.show{
    width:256px !important; 
}

I then added the following to the header.php in my child theme:

<script>
jQuery( window ).load(function () { 
    if( jQuery( '.wpcf7' ).length ){ 
        jQuery( '.grecaptcha-badge' ).addClass( 'show' );
    }
});
</script>

First, note that since Java is garbage-collected, it is rare to need to do anything about object destruction. Firstly because you don't usually have any managed resources to free, and secondly because you can't predict when or if it will happen, so it's inappropriate for things that you need to occur "as soon as nobody is using my object any more".

You can be notified after an object has been destroyed using java.lang.ref.PhantomReference (actually, saying it has been destroyed may be slightly inaccurate, but if a phantom reference to it is queued then it's no longer recoverable, which usually amounts to the same thing). A common use is:

• Separate out the resource(s) in your class that need to be destructed into another helper object (note that if all you're doing is closing a connection, which is a common case, you don't need to write a new class: the connection to be closed would be the "helper object" in that case).
• When you create your main object, create also a PhantomReference to it. Either have this refer to the new helper object, or set up a map from PhantomReference objects to their corresponding helper objects.
• After the main object is collected, the PhantomReference is queued (or rather it may be queued - like finalizers there is no guarantee it ever will be, for example if the VM exits then it won't wait). Make sure you're processing its queue (either in a special thread or from time to time). Because of the hard reference to the helper object, the helper object has not yet been collected. So do whatever cleanup you like on the helper object, then discard the PhantomReference and the helper will eventually be collected too.

There is also finalize(), which looks like a destructor but doesn't behave like one. It's usually not a good option.

1. You have to replace \n with <br/> before inset into database.

   $data = str_replace("\n", "<br/>", $data);

   In this case in database table you will see <br/> instead of new line.

   e.g.

   First Line
Second Line

   will look like:

   First Line<br/>Second Line

2. Another way to view data with new line. First read data from database. And then replace \n with <br/> e.g. :

   echo $data;
$data = str_replace("\n", "<br/>", $data);
echo "<br/><br/>" . $data;

   output:

   First Line Second Line

First Line
Second Line

   
   You will find details about function str_replace() here: http://php.net/manual/en/function.str-replace.php

Download the source package, open Terminal.app, navigate to the directory where you currently have the file, and then execute:

R CMD INSTALL RJSONIO_0.2-3.tar.gz

Do note that this will only succeed when either: a) the package does not need compilation or b) the needed system tools for compilation are present. See: https://cran.r-project.org/bin/macosx/tools/

Try this:

.menu a.main-nav-item:hover { }

In order to understand how this works it is important to read this the way the browser does. The a defines the element, the .main-nav-item qualifies the element to only those which have that class, and finally the psuedo-class :hover is applied to the qualified expression that comes before.

Basically it boils down to this:

Apply this hover rule to all anchor elements with the class main-nav-item that are a descendant child of any element with the class menu.

I recommend you to use enums :)

Check this out:

public enum Foo 
{
    BAR("bar"),
    BAZ("baz"),
    BAM("bam");

    private final String description;

    private Foo(String description)
    {
        this.description = description;
    }

    public String getDescription()
    {
        return description;
    }
}

Then you can use it like this:

System.out.println(Foo.BAR.getDescription());

The easiest way would be to flush the stream multiple times ( ideally larger then any possible console ) 1024*1024 is likely a size no console window could ever be.

int main(int argc, char *argv)
{
  for(int i = 0; i <1024*1024; i++)
      std::cout << ' ' << std::endl;

  return 0;
}

The only problem with this is the software cursor; that blinking thing ( or non blinking thing ) depending on platform / console will be at the end of the console, opposed to the top of it. However this should never induce any trouble hopefully.

The m2e plugin uses it's own distribution of Maven, packaged with the plugin.

In order to use Maven from command line, you need to have it installed as a standalone application. Here is an instruction explaining how to do it in Windows

Once Maven is properly installed (i.e. be sure that MAVEN_HOME, JAVA_HOME and PATH variables are set correctly): you must run mvn eclipse:eclipse from the directory containing the pom.xml.

Use the pointtype and pointsize options, e.g.

plot "./points.dat" using 1:2 pt 7 ps 10  

where pt 7 gives you a filled circle and ps 10 is the size.

See: Plotting data.

Are you sure the page you are redirecting too doesn't have a redirection within that if no session data is found? That could be your problem

Also yes always add whitespace like @Peter O suggested.

git log -p will show you not just the commit logs but also the diff of each commit (except merge commits). Then you can press /, enter filename and press enter. Press n or p to go to the next/previous occurrence. This way you will not just see the changes in the file but also the commit information.

Using http.createServer is very low-level and really not useful for creating web applications as-is.

A good framework to use on top of it is Express, and I would seriously suggest using it. You can install it using npm install express.

When you have, you can create a basic application to handle your form:

var express = require('express');
var bodyParser = require('body-parser');
var app     = express();

//Note that in version 4 of express, express.bodyParser() was
//deprecated in favor of a separate 'body-parser' module.
app.use(bodyParser.urlencoded({ extended: true })); 

//app.use(express.bodyParser());

app.post('/myaction', function(req, res) {
  res.send('You sent the name "' + req.body.name + '".');
});

app.listen(8080, function() {
  console.log('Server running at http://127.0.0.1:8080/');
});

You can make your form point to it using:

<form action="http://127.0.0.1:8080/myaction" method="post">

The reason you can't run Node on port 80 is because there's already a process running on that port (which is serving your index.html). You could use Express to also serve static content, like index.html, using the express.static middleware.

Try:

sudo /etc/init.d/mysql reload

or

sudo /etc/init.d/mysql force-reload

That should initiate a reload of the configuration. Make sureyour init.d script supports it though, I don't know what version of MySQL/OS you are using?

My MySQL script contains the following:

'reload'|'force-reload')
        log_daemon_msg "Reloading MySQL database server" "mysqld"
        $MYADMIN reload
        log_end_msg 0
        ;;

Messed around at regexpal and ended up with this regex: (Don't ask me how it works, I barely understand even tho I wrote it lol)

"(([^"\\]?(\\\\)?)|(\\")+)+"

for /f "tokens=* delims= " %%f in (myfile) do

This reads a file line-by-line, removing leading spaces (thanks, jeb).

set line=%%f

sets then the line variable to the line just read and

call :procesToken

calls a subroutine that does something with the line

:processToken

is the start of the subroutine mentioned above.

for /f "tokens=1* delims=/" %%a in ("%line%") do

will then split the line at /, but stopping tokenization after the first token.

echo Got one token: %%a

will output that first token and

set line=%%b

will set the line variable to the rest of the line.

if not "%line%" == "" goto :processToken

And if line isn't yet empty (i.e. all tokens processed), it returns to the start, continuing with the rest of the line.

 XmlReaderSettings _configsettings = new XmlReaderSettings();
 _configsettings.IgnoreComments = true;

 XmlReader _configreader = XmlReader.Create(ConfigFilePath, _configsettings);
 XmlDocument doc_config = new XmlDocument();
 doc_config.Load(_configreader);
 _configreader.Close();

 foreach (XmlNode RootName in doc_config.DocumentElement.ChildNodes)
 {
     if (RootName.LocalName == "appSettings")
     {
         if (RootName.HasChildNodes)
         {
             foreach (XmlNode _child in RootName.ChildNodes)
             {
                 if (_child.Attributes["key"].Value == "HostName")
                 {
                     if (_child.Attributes["value"].Value == "false")
                         _child.Attributes["value"].Value = "true";
                 }
             }
         }
     }
 }
 doc_config.Save(ConfigFilePath);

You can increment the stack depth allowed - with this, deeper recursive calls will be possible, like this:

import sys
sys.setrecursionlimit(10000) # 10000 is an example, try with different values

... But I'd advise you to first try to optimize your code, for instance, using iteration instead of recursion.

The possibility could be, the SSH might not be enabled on your server/system.

1. Check sudo systemctl status ssh is Active or not.
2. If it's not active, try installing with the help of these commands

sudo apt update

sudo apt install openssh-server

Now try to access the server/system with following command

ssh username@ip_address

Business rules go in the model.

Say you were displaying emails for a mailing list. The user clicks the "delete" button next to one of the emails, the controller notifies the model to delete entry N, then notifies the view the model has changed.

Perhaps the admin's email should never be removed from the list. That's a business rule, that knowledge belongs in the model. The view may ultimately represent this rule somehow -- perhaps the model exposes an "IsDeletable" property which is a function of the business rule, so that the delete button in the view is disabled for certain entries - but the rule itself isn't contained in the view.

The model is ultimately gatekeeper for your data. You should be able to test your business logic without touching the UI at all.

This may also be useful: {{ form.field.as_hidden }}

The next link will bring you to a great tutorial, that helped me a lot!

How to SQLITE in C#

I nearly used everything in that article to create the SQLite database for my own C# Application.

Don't forget to download the SQLite.dll, and add it as a reference to your project. This can be done using NuGet and by adding the dll manually.

After you added the reference, refer to the dll from your code using the following line on top of your class:

using System.Data.SQLite;

You can find the dll's here:

SQLite DLL's

You can find the NuGet way here:

NuGet

Up next is the create script. Creating a database file:

SQLiteConnection.CreateFile("MyDatabase.sqlite");

SQLiteConnection m_dbConnection = new SQLiteConnection("Data Source=MyDatabase.sqlite;Version=3;");
m_dbConnection.Open();

string sql = "create table highscores (name varchar(20), score int)";

SQLiteCommand command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();

sql = "insert into highscores (name, score) values ('Me', 9001)";

command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();

m_dbConnection.Close();

After you created a create script in C#, I think you might want to add rollback transactions, it is safer and it will keep your database from failing, because the data will be committed at the end in one big piece as an atomic operation to the database and not in little pieces, where it could fail at 5th of 10 queries for example.

Example on how to use transactions:

 using (TransactionScope tran = new TransactionScope())
 {
     //Insert create script here.

     //Indicates that creating the SQLiteDatabase went succesfully, so the database can be committed.
     tran.Complete();
 }

Try this:

 private void cleanlistbox(object sender, EventArgs e)
  {
     listBox1.DataSource = null;
     listBox1.Items.Clear();
  }

Install & Add Material to Angular Projects

There is an automatic/easy way of adding Material to Angular Projects. Use the Angular CLI's install schematic to set up your Angular Material project by running the following command:

ng add @angular/material

The ng add command will additionally perform the following configurations:

• Add project dependencies to package.json
• Add the Roboto font to your index.html
• Add the Material Design icon font to your index.html
• Add a few global CSS styles to:
  • Remove margins from body
  • Set height: 100% on html and body
  • Set Roboto as the default application font

You're done! Angular Material is now configured to be used in your application.

This is what worked for me perfectly:-

// slide the view from its current position to below itself
public void slideUp(final View view, final View llDomestic){

    ObjectAnimator animation = ObjectAnimator.ofFloat(view, "translationY",0f);
    animation.setDuration(100);
    llDomestic.setVisibility(View.GONE);
    animation.start();

}

// slide the view from below itself to the current position
public void slideDown(View view,View llDomestic){
    llDomestic.setVisibility(View.VISIBLE);
    ObjectAnimator animation = ObjectAnimator.ofFloat(view, "translationY",   0f);
    animation.setDuration(100);
    animation.start();
}

llDomestic : The view which you want to hide. view: The view which you want to move down or up.

You need to import the module datetime first:

>>> import datetime

After that it works:

>>> import datetime
>>> date = datetime.date.today()
>>> date
datetime.date(2013, 11, 12)

If it's open to a modification, you could use a suffix instead of a prefix. Then you could use tab-completion to get the original filename and add the suffix.

Otherwise, no this isn't something that is supported by the mv command. A simple shell script could cope though.

You don't really need it today, because the current standard makes it optional -- and every useful browser currently assumes that a style sheet is CSS, even in versions of HTML that considered the attribute "required".

With HTML being a "living standard" now, though -- and thus subject to change -- you can only guarantee so much. And there's no new DTD that you can point to and say the page was written for that version of HTML, and no reliable way even to say "HTML as of such-and-such a date". For forward-compatibility reasons, in my opinion, you should specify the type.

Use the Log class. Output visible with LogCat

I think to add timestamp to every record and get the latest. In this situation you can get any ids, pack rows and other ops.

use android:drawbleStart propery on EditText

    <EditText

This helped to me (in ionic, but idea is the same) https://mhartington.io/post/setting-input-focus/

in template:

<ion-item>
      <ion-label>Home</ion-label>
      <ion-input #input type="text"></ion-input>
</ion-item>
<button (click)="focusInput(input)">Focus</button>

in controller:

  focusInput(input) {
    input.setFocus();
  }

Instead of using:

self.present(viewControllerToPresent: UIViewController, animated: Bool, completion: (() -> Void)?)

you can use:

self.navigationController?.pushViewController(viewController: UIViewController, animated: Bool)

if explode is used together with foreach to build a new string you can simulate explode by using a while loop like this:

CREATE FUNCTION explode_and_loop(sep VARCHAR(),inputstring VARCHAR()) RETURNS VARCHAR() 
BEGIN
    DECLARE part,returnstring VARCHAR();
    DECLARE cnt,partsCnt INT();
    SET returnstring = '';
    SET partsCnt = ((LENGTH(inputstring ) - LENGTH(REPLACE(inputstring,sep,''))) DIV LENGTH(sep);
    SET cnt = 0;
    WHILE cnt <= partsCnt DO
        SET cnt = cnt + 1;
        SET part = SUBSTRING_INDEX(SUBSTRING_INDEX(inputstring ,sep,cnt),sep,-1);
        -- DO SOMETHING with the part eg make html:
        SET returnstring = CONCAT(returnstring,'<li>',part,'</li>')
    END WHILE;
    RETURN returnstring;
END

this example will return a html list of the parts. (required variable legths have to be added)

This may work for you. I used it for cleaning folders during deployments for deleting old deployment files.

clean_anyfolder() {
    local temp2="$1/**"; //PATH
    temp3=( $(ls -d $temp2 -t | grep "`date | awk '{print $2" "$3}'`") )
    j=0;
    while [ $j -lt ${#temp3[@]} ]
    do
            echo "to be removed ${temp3[$j]}"
            delete_file_or_folder ${temp3[$j]} 0 //DELETE HERE
        fi
        j=`expr $j + 1`
    done
}

I have personally found some errors in when using unix_timestamp based date converstions from dd-MMM-yyyy format to yyyy-mm-dd, using spark 1.6, but this may extend into recent versions. Below I explain a way to solve the problem using java.time that should work in all versions of spark:

I've seen errors when doing:

from_unixtime(unix_timestamp(StockMarketClosingDate, 'dd-MMM-yyyy'), 'yyyy-MM-dd') as FormattedDate

Below is code to illustrate the error, and my solution to fix it. First I read in stock market data, in a common standard file format:

    import sys.process._
    import org.apache.spark.sql.SQLContext
    import org.apache.spark.sql.functions.udf
    import org.apache.spark.sql.types.{StructType, StructField, StringType, IntegerType, DateType}
    import sqlContext.implicits._

    val EODSchema = StructType(Array(
        StructField("Symbol"                , StringType, true),     //$1       
        StructField("Date"                  , StringType, true),     //$2       
        StructField("Open"                  , StringType, true),     //$3       
        StructField("High"                  , StringType, true),     //$4
        StructField("Low"                   , StringType, true),     //$5
        StructField("Close"                 , StringType, true),     //$6
        StructField("Volume"                , StringType, true)      //$7
        ))

    val textFileName = "/user/feeds/eoddata/INDEX/INDEX_19*.csv"

    // below is code to read using later versions of spark
    //val eoddata = spark.read.format("csv").option("sep", ",").schema(EODSchema).option("header", "true").load(textFileName)


    // here is code to read using 1.6, via, "com.databricks:spark-csv_2.10:1.2.0"

    val eoddata = sqlContext.read
                               .format("com.databricks.spark.csv")
                               .option("header", "true")                               // Use first line of all files as header
                               .option("delimiter", ",")                               //.option("dateFormat", "dd-MMM-yyyy") failed to work
                               .schema(EODSchema)
                               .load(textFileName)

    eoddata.registerTempTable("eoddata")

And here is the date conversions having issues:

%sql 
-- notice there are errors around the turn of the year
Select 
    e.Date as StringDate
,   cast(from_unixtime(unix_timestamp(e.Date, "dd-MMM-yyyy"), 'YYYY-MM-dd') as Date)  as ProperDate
,   e.Close
from eoddata e
where e.Symbol = 'SPX.IDX'
order by cast(from_unixtime(unix_timestamp(e.Date, "dd-MMM-yyyy"), 'YYYY-MM-dd') as Date)
limit 1000

A chart made in zeppelin shows spikes, which are errors.

and here is the check that shows the date conversion errors:

// shows the unix_timestamp conversion approach can create errors
val result =  sqlContext.sql("""
Select errors.* from
(
    Select 
    t.*
    , substring(t.OriginalStringDate, 8, 11) as String_Year_yyyy 
    , substring(t.ConvertedCloseDate, 0, 4)  as Converted_Date_Year_yyyy
    from
    (        Select
                Symbol
            ,   cast(from_unixtime(unix_timestamp(e.Date, "dd-MMM-yyyy"), 'YYYY-MM-dd') as Date)  as ConvertedCloseDate
            ,   e.Date as OriginalStringDate
            ,   Close
            from eoddata e
            where e.Symbol = 'SPX.IDX'
    ) t

FINISHED   

After this result, I switched to java.time conversions with a UDF like this, which worked for me:

// now we will create a UDF that uses the very nice java.time library to properly convert the silly stockmarket dates
// start by importing the specific java.time libraries that superceded the joda.time ones
import java.time.LocalDate
import java.time.format.DateTimeFormatter

// now define a specific data conversion function we want

def fromEODDate (YourStringDate: String): String = {

    val formatter = DateTimeFormatter.ofPattern("dd-MMM-yyyy")
    var   retDate = LocalDate.parse(YourStringDate, formatter)

    // this should return a proper yyyy-MM-dd date from the silly dd-MMM-yyyy formats
    // now we format this true local date with a formatter to the desired yyyy-MM-dd format

    val retStringDate = retDate.format(DateTimeFormatter.ISO_LOCAL_DATE)
    return(retStringDate)
}

Now I register it as a function for use in sql:

sqlContext.udf.register("fromEODDate", fromEODDate(_:String))

and check the results, and rerun test:

val results = sqlContext.sql("""
    Select
        e.Symbol    as Symbol
    ,   e.Date      as OrigStringDate
    ,   Cast(fromEODDate(e.Date) as Date) as ConvertedDate
    ,   e.Open

    ,   e.Low
    ,   e.Close
    from eoddata e
    order by Cast(fromEODDate(e.Date) as Date)
""")

results.printSchema()
results.cache()
results.registerTempTable("results")
results.show(10)

only showing top 10 rows

which looks ok, and I rerun my chart, to see if there are errors/spikes:

As you can see, no more spikes or errors. I now use a UDF as I've shown to apply my date format transformations to a standard yyyy-MM-dd format, and have not had spurious errors since. :-)

If you're getting this bug with Xcode Beta, it's a beta bug and can be ignored (as far as I've been told). If you can build and run on a release build of Xcode without this error, then it is not your app that has the problem.

Not 100% on this, but see if this fixes the problem:

iOS Simulator -> Hardware -> Keyboard -> Toggle Software Keyboard.

Then, everything works

Go to file->export->JAR file, there you may select "Export generated class files and sources" and make sure that your project is selected, and all folder under there are also! Good luck!

I needed to make a ListView with items of different colors. I modified Shardul's method a bit and result in this:

ArrayAdapter<String> adapter = new ArrayAdapter<String>(
                this, android.R.layout.simple_list_item_1, colorString) {
            @Override
            public View getView(int position, View convertView, ViewGroup parent) {
                TextView textView = (TextView) super.getView(position, convertView, parent);
                textView.setBackgroundColor(assignBackgroundColor(position));
                textView.setTextColor(assignTextColor(position));
                return textView;
            }
        };
        colorList.setAdapter(adapter);

assignBackgroundColor() and assignTextColor() are methods that assign color you want. They can be replaced with int[] arrays.

setDate only seems to be an issue with an inline datepicker used in jquery UI, the specific error is InternalError: too much recursion.

If you are going to use it with Retrofit library, I suggest you to use Square's gson library as:

implementation 'com.squareup.retrofit2:converter-gson:2.4.0'

To generate a certificate on the Apple provisioning profile website, firstly you have to generate keys on your mac, then upload the public key. Apple will generate your certificates with this key. When you download your certificates, tu be able to use them you need to have the private key.

The error "XCode could not find a valid private-key/certificate pair for this profile in your keychain." means you don't have the private key.

Maybe because your Mac was reinstalled, maybe because this key was generated on another Mac. So to be able to use your certificates, you need to find this key and install it on the keychain.

If you can not find it you can generate new keys restart this process on the provisioning profile website and get new certificates you will able to use.

The problem

The problem is in the network layer. Here are the status codes explained:

• Connection refused: The peer is not listening on the respective network port you're trying to connect to. This usually means that either a firewall is actively denying the connection or the respective service is not started on the other site or is overloaded.

• Connection timed out: During the attempt to establish the TCP connection, no response came from the other side within a given time limit. In the context of urllib this may also mean that the HTTP response did not arrive in time. This is sometimes also caused by firewalls, sometimes by network congestion or heavy load on the remote (or even local) site.

In context

That said, it is probably not a problem in your script, but on the remote site. If it's occuring occasionally, it indicates that the other site has load problems or the network path to the other site is unreliable.

Also, as it is a problem with the network, you cannot tell what happened on the other side. It is possible that the packets travel fine in the one direction but get dropped (or misrouted) in the other.

It is also not a (direct) DNS problem, that would cause another error (Name or service not known or something similar). It could however be the case that the DNS is configured to return different IP addresses on each request, which would connect you (DNS caching left aside) to different addresses hosts on each connection attempt. It could in turn be the case that some of these hosts are misconfigured or overloaded and thus cause the aforementioned problems.

Debugging this

As suggested in the another answer, using a packet analyzer can help to debug the issue. You won't see much however except the packets reflecting exactly what the error message says.

To rule out network congestion as a problem you could use a tool like mtr or traceroute or even ping to see if packets get lost to the remote site. Note that, if you see loss in mtr (and any traceroute tool for that matter), you must always consider the first host where loss occurs (in the route from yours to remote) as the one dropping packets, due to the way ICMP works. If the packets get lost only at the last hop over a long time (say, 100 packets), that host definetly has an issue. If you see that this behaviour is persistent (over several days), you might want to contact the administrator.

Loss in a middle of the route usually corresponds to network congestion (possibly due to maintenance), and there's nothing you could do about it (except whining at the ISP about missing redundance).

If network congestion is not a problem (i.e. not more than, say, 5% of the packets get lost), you should contact the remote server administrator to figure out what's wrong. He may be able to see relevant infos in system logs. Running a packet analyzer on the remote site might also be more revealing than on the local site. Checking whether the port is open using netstat -tlp is definetly recommended then.

Make sure you are on the Lastest version

implementation 'com.github.bumptech.glide:glide:4.10.0'

Kotlin:

Glide.with(this)
        .asBitmap()
        .load(imagePath)
        .into(object : CustomTarget<Bitmap>(){
            override fun onResourceReady(resource: Bitmap, transition: Transition<in Bitmap>?) {
                imageView.setImageBitmap(resource)
            }
            override fun onLoadCleared(placeholder: Drawable?) {
                // this is called when imageView is cleared on lifecycle call or for
                // some other reason.
                // if you are referencing the bitmap somewhere else too other than this imageView
                // clear it here as you can no longer have the bitmap
            }
        })

Bitmap Size:

if you want to use the original size of the image use the default constructor as above, else You can pass your desired size for bitmap

into(object : CustomTarget<Bitmap>(1980, 1080)

Java:

Glide.with(this)
        .asBitmap()
        .load(path)
        .into(new CustomTarget<Bitmap>() {
            @Override
            public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {
                imageView.setImageBitmap(resource);
            }

            @Override
            public void onLoadCleared(@Nullable Drawable placeholder) {
            }
        });

Old Answer:

With compile 'com.github.bumptech.glide:glide:4.8.0' and below

Glide.with(this)
        .asBitmap()
        .load(path)
        .into(new SimpleTarget<Bitmap>() {
            @Override
            public void onResourceReady(Bitmap resource, Transition<? super Bitmap> transition) {
                imageView.setImageBitmap(resource);
            }
        });

For compile 'com.github.bumptech.glide:glide:3.7.0' and below

Glide.with(this)
        .load(path)
        .asBitmap()
        .into(new SimpleTarget<Bitmap>() {
            @Override
            public void onResourceReady(Bitmap resource, GlideAnimation<? super Bitmap> glideAnimation) {
                imageView.setImageBitmap(resource);
            }
        });

Now you might see a warning SimpleTarget is deprecated

Reason:

The main point of deprecating SimpleTarget is to warn you about the ways in which it tempts you to break Glide's API contract. Specifically, it doesn't do anything to force you to stop using any resource you've loaded once the SimpleTarget is cleared, which can lead to crashes and graphical corruption.

The SimpleTarget still can be used as long you make sure you are not using the bitmap once the imageView is cleared.

I was also facing the same issue where I was receiving the Transaction_Date as YYYYMMDD in bigint format. So I converted it into Datetime format using below query and saved it in new column with datetime format. I hope this will help you as well.

SELECT
convert( Datetime, STUFF(STUFF(Transaction_Date, 5, 0, '-'), 8, 0, '-'), 120) As [Transaction_Date_New]
FROM mydb

Try putting the following in the header:

Courtesy Paul Irish's HTML5 Boilerplate (but it works in XHTML Transitional, too).

Use

table.put(key, val);

to add a new key/value pair or overwrite an existing key's value.

From the Javadocs:

V put(K key, V value): Associates the specified value with the specified key in this map (optional operation). If the map previously contained a mapping for the key, the old value is replaced by the specified value. (A map m is said to contain a mapping for a key k if and only if m.containsKey(k) would return true.)

If you have reason to avoid the use of the datetime module, then these functions will work.

Use the system stored procedure sp_who2.

ad 1. It does not implement its methods.

ad 4. The purpose of one interface extending, not implementing another, is to build a more specific interface. For example, SortedMap is an interface that extends Map. A client not interested in the sorting aspect can code against Map and handle all the instances of for example TreeMap, which implements SortedMap. At the same time, another client interested in the sorted aspect can use those same instances through the SortedMap interface.

In your example you are repeating the methods from the superinterface. While legal, it's unnecessary and doesn't change anything in the end result. The compiled code will be exactly the same whether these methods are there or not. Whatever Eclipse's hover says is irrelevant to the basic truth that an interface does not implement anything.

Usually to use the library you need to install the dev version.

Try

sudo apt-get install libusb-1.0-0-dev

Simply because you don't have c++ compiler installed there in your machine, check the following

• Download Microsoft Visual C++ 2008 from this page. That is a generally useful page anyway, so you should probably bookmark it. For Python 3.3+ use MS Visual C++ 2010. Install it.

• Open Windows explorer (the file browser) and search for the location of ‘vcvarsall.bat’ and cut it to your clipboard.

• run regedit from the Windows start key. You will need admin privilges.

• Add a registry entry to HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\VisualStudio\9.0\Setup\VC\ProductDir (64 bit Windows) or HKEY_LOCAL_MACHINE\Software\Microsoft\VisualStudio\9.0\Setup\VC\ProductDir (32 bit) as described here.

Hint: 0.9 in the registery directory is the currently installed version of your visual studio, if you running VS 2013, you have to find the path HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\VisualStudio\12.0....

• At the Windows start key, type cmd to get a command shell. If you need to, go to your virtual environment and run activate.bat.

• pip install or whatever you use to install it.

Just use indexOf:

haystack.indexOf(needle) >= 0

If you want to support old Internet Explorers (< IE9), you'll have to include your current code as a workaround though.

Unless your list is sorted, you need to compare every value to the needle. Therefore, both your solution and indexOf will have to execute n/2 comparisons on average. However, since indexOf is a built-in method, it may use additional optimizations and will be slightly faster in practice. Note that unless your application searches in lists extremely often (say a 1000 times per second) or the lists are huge (say 100k entries), the speed difference will not matter.

Simply try this

It's another way

public enum CaseOriginCode
{
    Web = 0,
    Email = 1,
    Telefoon = 2
}

public void setCaseOriginCode(string CaseOriginCode)
{
    int caseOriginCode = (int)(CaseOriginCode)Enum.Parse(typeof(CaseOriginCode), CaseOriginCode);
}

If you have installed Apache with OpenSSL navigate to bin directory. In my case D:\apache\bin.

*These commands also work if you have stand alone installation of openssl.

Run these commands:

openssl req -config d:\apache\conf\openssl.cnf -new -out d:\apache\conf\server.csr -keyout d:\apache\conf\server.pem
openssl rsa -in d:\apache\conf\server.pem -out d:\apache\conf\server.key
openssl x509 -in d:\apache\conf\server.csr -out d:\apache\conf\server.crt -req -signkey d:\apache\conf\server.key -days 365

*This will create self-signed certificate that you can use for development purposes

Again if you have Apache installed in the httpd.conf stick these:

  <IfModule ssl_module>
    SSLEngine on
    SSLCertificateFile "D:/apache/conf/server.crt"
    SSLCertificateKeyFile "D:/apache/conf/server.key"
  </IfModule>

Decimal has a fixed precision while float has variable precision.

EDIT (failed to read entire question): Float(53) (aka real) is a double-precision (64-bit) floating point number in SQL Server. Regular Float is a single-precision (32-bit) floating point number. Double is a good combination of precision and simplicty for a lot of calculations. You can create a very high precision number with decimal -- up to 136-bit -- but you also have to be careful that you define your precision and scale correctly so that it can contain all your intermediate calculations to the necessary number of digits.

The way I would do this manually is:

• Use Data - AutoFilter
• Apply a custom filter based on a date range
• Copy the filtered data to the relevant month sheet
• Repeat for every month

Listed below is code to do this process via VBA.

It has the advantage of handling monthly sections of data rather than individual rows. Which can result in quicker processing for larger sets of data.

    Sub SeperateData()

    Dim vMonthText As Variant
    Dim ExcelLastCell As Range
    Dim intMonth As Integer

   vMonthText = Array("January", "February", "March", "April", "May", _
 "June", "July", "August", "September", "October", "November", "December")

        ThisWorkbook.Worksheets("Sharepoint").Select
        Range("A1").Select

    RowCount = ThisWorkbook.Worksheets("Sharepoint").UsedRange.Rows.Count
'Forces excel to determine the last cell, Usually only done on save
    Set ExcelLastCell = ThisWorkbook.Worksheets("Sharepoint"). _
     Cells.SpecialCells(xlLastCell)
'Determines the last cell with data in it


        Selection.EntireColumn.Insert
        Range("A1").FormulaR1C1 = "Month No."
        Range("A2").FormulaR1C1 = "=MONTH(RC[1])"
        Range("A2").Select
        Selection.Copy
        Range("A3:A" & ExcelLastCell.Row).Select
        ActiveSheet.Paste
        Application.CutCopyMode = False
        Calculate
    'Insert a helper column to determine the month number for the date

        For intMonth = 1 To 12
            Range("A1").CurrentRegion.Select
            Selection.AutoFilter Field:=1, Criteria1:="" & intMonth
            Selection.Copy
            ThisWorkbook.Worksheets("" & vMonthText(intMonth - 1)).Select
            Range("A1").Select
            ActiveSheet.Paste
            Columns("A:A").Delete Shift:=xlToLeft
            Cells.Select
            Cells.EntireColumn.AutoFit
            Range("A1").Select
            ThisWorkbook.Worksheets("Sharepoint").Select
            Range("A1").Select
            Application.CutCopyMode = False
        Next intMonth
    'Filter the data to a particular month
    'Convert the month number to text
    'Copy the filtered data to the month sheet
    'Delete the helper column
    'Repeat for each month

        Selection.AutoFilter
        Columns("A:A").Delete Shift:=xlToLeft
 'Get rid of the auto-filter and delete the helper column

    End Sub

You can use forever-service for doing this.

npm install -g forever-service
forever-service install test

This will provision app.js in the current directory as a service via forever. The service will automatically restart every time system is restarted. Also when stopped it will attempt a graceful stop. This script provisions the logrotate script as well.

NOTE: I am the author of forever-service.

update:

I found the terms of use from Google Map:

Section 10.5

No caching or storage. You will not pre-fetch, cache, index, or store any Content to be used outside the Service, except that you may store limited amounts of Content solely for the purpose of improving the performance of your Maps API Implementation due to network latency (and not for the purpose of preventing Google from accurately tracking usage), and only if such storage: is temporary (and in no event more than 30 calendar days); is secure; does not manipulate or aggregate any part of the Content or Service; and does not modify attribution in any way.

It means we can cache for limited time actually

Aside from personal design preferences, there are cases where one wants to make use of composite primary keys. Tables may have two or more fields that provide a unique combination, and not necessarily by way of foreign keys.

As an example, each US state has a set of unique Congressional districts. While many states may individually have a CD-5, there will never be more than one CD-5 in any of the 50 states, and vice versa. Therefore, creating an autonumber field for Massachusetts CD-5 would be redundant.

If the database drives a dynamic web page, writing code to query on a two-field combination could be much simpler than extracting/resubmitting an autonumbered key.

So while I'm not answering the original question, I certainly appreciate Adam's direct answer.

I would suggest adding class no-js to your html to nest your CSS selectors under it like:

.loading {
    display: none;
 }

.no-js .loading {
 display: block;
 //....
}

and when you finish loading your credit code remove it:

$('html').removeClass('no-js');

This will hide your loading spinner as there's no no-js class in html it means you already loaded your credit code

Yes, fill in a Rectangle with a solid color across the canvas, use the height and width of the canvas itself:

var canvas = document.getElementById("canvas");
var ctx = canvas.getContext("2d");
ctx.fillStyle = "blue";
ctx.fillRect(0, 0, canvas.width, canvas.height);

canvas{ border: 1px solid black; }

<canvas width=300 height=150 id="canvas">

array1.equals(array2) is the same as array1 == array2, i.e. is it the same array. As @alf points out it's not what most people expect.

Arrays.equals(array1, array2) compares the contents of the arrays.

Similarly array.toString() may not be very useful and you need to use Arrays.toString(array).

To link means not to work properly. Digging into stdio.h of VS2012 and VS2015 the following worked for me. Alas, you have to decide if it should work for one of { stdin, stdout, stderr }, never more than one.

extern "C" FILE* __cdecl __iob_func()
{
    struct _iobuf_VS2012 { // ...\Microsoft Visual Studio 11.0\VC\include\stdio.h #56
        char *_ptr;
        int   _cnt;
        char *_base;
        int   _flag;
        int   _file;
        int   _charbuf;
        int   _bufsiz;
        char *_tmpfname; };
    // VS2015 has only FILE = struct {void*}

    int const count = sizeof(_iobuf_VS2012) / sizeof(FILE);

    //// stdout
    //return (FILE*)(&(__acrt_iob_func(1)->_Placeholder) - count);

    // stderr
    return (FILE*)(&(__acrt_iob_func(2)->_Placeholder) - 2 * count);
}

You can do:

hash=$(genhash --use-ssl -s $IP -p 443 --url $URL)

or

hash=`genhash --use-ssl -s $IP -p 443 --url $URL`

If you want to result of the entire pipe to be assigned to the variable, you can use the entire pipeline in the above assignments.

The reason I used a + instead of a '*' is because a plus is defined as one or more of the preceding element, where an asterisk is zero or more. In this case we want a delimiter that's a little more concrete, so "one or more" spaces.

word[Aa]\s+word[Bb]\s+word[Cc]

will match:

wordA wordB     wordC
worda wordb wordc
wordA   wordb   wordC

The words, in this expression, will have to be specific, and also in order (a, b, then c)

Just put context.SaveChanges() after end of your foreach(loop).

df[df['ids'].str.contains('ball', na = False)] # valid for (at least) pandas version 0.17.1

Step-by-step explanation (from inner to outer):

• df['ids'] selects the ids column of the data frame (technically, the object df['ids'] is of type pandas.Series)
• df['ids'].str allows us to apply vectorized string methods (e.g., lower, contains) to the Series
• df['ids'].str.contains('ball') checks each element of the Series as to whether the element value has the string 'ball' as a substring. The result is a Series of Booleans indicating True or False about the existence of a 'ball' substring.
• df[df['ids'].str.contains('ball')] applies the Boolean 'mask' to the dataframe and returns a view containing appropriate records.
• na = False removes NA / NaN values from consideration; otherwise a ValueError may be returned.

Try this:

 git fetch --all
 git reset --hard origin/master

Explanation:

git fetch downloads the latest from remote without trying to merge or rebase anything.

Please let me know if you have any questions!

I know this is old, but i think i have good solution. Comparing to other answers and also comparing to accepted, mine accepts multiple values. Basically filter object with key:value search parameters (also object within object). Also it works with numbers etc, cause when comparing, it converts them to string.

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({name: 'filter'})
export class Filter implements PipeTransform {
    transform(array: Array<Object>, filter: Object): any {
        let notAllKeysUndefined = false;
        let newArray = [];

        if(array.length > 0) {
            for (let k in filter){
                if (filter.hasOwnProperty(k)) {
                    if(filter[k] != undefined && filter[k] != '') {
                        for (let i = 0; i < array.length; i++) {
                            let filterRule = filter[k];

                            if(typeof filterRule === 'object') {
                                for(let fkey in filterRule) {
                                    if (filter[k].hasOwnProperty(fkey)) {
                                        if(filter[k][fkey] != undefined && filter[k][fkey] != '') {
                                            if(this.shouldPushInArray(array[i][k][fkey], filter[k][fkey])) {
                                                newArray.push(array[i]);
                                            }
                                            notAllKeysUndefined = true;
                                        }
                                    }
                                }
                            } else {
                                if(this.shouldPushInArray(array[i][k], filter[k])) {
                                    newArray.push(array[i]);
                                }
                                notAllKeysUndefined = true;
                            }
                        }
                    }
                }
            }
            if(notAllKeysUndefined) {
                return newArray;
            }
        }

        return array;
    }

    private shouldPushInArray(item, filter) {
        if(typeof filter !== 'string') {
            item = item.toString();
            filter = filter.toString();
        }

        // Filter main logic
        item = item.toLowerCase();
        filter = filter.toLowerCase();
        if(item.indexOf(filter) !== -1) {
            return true;
        }
        return false;
    }
}

I had the same problem, when I needed to reset all the collections but didn't want to loose any database users. Use the following line of code, if you would like to save the user configuration for the database:

use <whichever database>
db.getCollectionNames().forEach(function(c) { if (c.indexOf("system.") == -1) db[c].drop(); })

This code will go through all collection names from one database and drop those which do not start with "system.".

One of the reason may be if any one of table column have an underscore(_) in its name . That is considered as invalid characters by the JDBC . Rename the column by a ALTER Command and change in your code SQL , that will fix .

The accepted answer didn't work for me but the following did:

>PsExec.exe \\<SERVER FQDN> -u <DOMAIN\USER> -p <PASSWORD> /accepteula cmd 
    /c "powershell -noninteractive -command gci c:\"

Example from here

Quick sort is an in-place sorting algorithm, so its better suited for arrays. Merge sort on the other hand requires extra storage of O(N), and is more suitable for linked lists.

Unlike arrays, in liked list we can insert items in the middle with O(1) space and O(1) time, therefore the merge operation in merge sort can be implemented without any extra space. However, allocating and de-allocating extra space for arrays have an adverse effect on the run time of merge sort. Merge sort also favors linked list as data is accessed sequentially, without much random memory access.

Quick sort on the other hand requires a lot of random memory access and with an array we can directly access the memory without any traversing as required by linked lists. Also quick sort when used for arrays have a good locality of reference as arrays are stored contiguously in memory.

Even though both sorting algorithms average complexity is O(NlogN), usually people for ordinary tasks uses an array for storage, and for that reason quick sort should be the algorithm of choice.

EDIT: I just found out that merge sort worst/best/avg case is always nlogn, but quick sort can vary from n2(worst case when elements are already sorted) to nlogn(avg/best case when pivot always divides the array in two halves).

For simple situations like the exact example in the OP, I agree that Thierry's answer is the best. However, I think it's useful to point out another approach that becomes easier when you're trying to maintain consistent color schemes across multiple data frames that are not all obtained by subsetting a single large data frame. Managing the factors levels in multiple data frames can become tedious if they are being pulled from separate files and not all factor levels appear in each file.

One way to address this is to create a custom manual colour scale as follows:

#Some test data
dat <- data.frame(x=runif(10),y=runif(10),
        grp = rep(LETTERS[1:5],each = 2),stringsAsFactors = TRUE)

#Create a custom color scale
library(RColorBrewer)
myColors <- brewer.pal(5,"Set1")
names(myColors) <- levels(dat$grp)
colScale <- scale_colour_manual(name = "grp",values = myColors)

and then add the color scale onto the plot as needed:

#One plot with all the data
p <- ggplot(dat,aes(x,y,colour = grp)) + geom_point()
p1 <- p + colScale

#A second plot with only four of the levels
p2 <- p %+% droplevels(subset(dat[4:10,])) + colScale

The first plot looks like this:

and the second plot looks like this:

This way you don't need to remember or check each data frame to see that they have the appropriate levels.

Still an issue.

Using parameters like "..css?something=random-value" changes nothing in my customer-support experience. Only name changes works.

Another take on the file renaming. I use URL Rewrite in IIS. Sometimes Helicon's Isapi Rewrite.

Add new rule.

+ Name: lame-chrome-fix.
+ Pattern: styles/(\w+)_(\d+)
+ Rewrite URL: /{R:1}.css

Note: I reserve the use of undercase to separate the name from the random number. Could be anything else.

Example:

<link href="/styles/template_<% 
Response.Write( System.DateTime.UtcNow.ToString("ddmmyyhhmmss")); %>" 
type="text/css" />

(No styles folder it's just a name part of the pattern)

Output code as:

<link href="/styles/template_285316115328" 
rel="stylesheet" type="text/css">

Redirect as:

(R:1 = template)

/template.css

Only the explanation is long.

You can set the environment variable through process global variable as follows:

process.env['NODE_ENV'] = 'production';

Works in all platforms.

In Java 8 you can do this to add all elements from an Iterable to Collection and return it:

public static <T> Collection<T> iterableToCollection(Iterable<T> iterable) {
  Collection<T> collection = new ArrayList<>();
  iterable.forEach(collection::add);
  return collection;
}

Inspired by @Afreys answer.

Like well explained in the link below, an identifying relation is somewhat like a weak entity type relation to its parent in the ER conceptual model. UML style CADs for data modeling do not use ER symbols or concepts, and the kind of relations are: identifying, non-identifying and non-specific.

Identifying ones are relations parent/child where the child is kind of a weak entity (even at the traditional ER model its called identifying relationship), which does not have a real primary key by its own attributes and therefore cannot be identified uniquely by its own. Every access to the child table, on the physical model, will be dependent (inclusive semantically) on the parent's primary key, which turns into part or total of the child's primary key (also being a foreign key), generally resulting in a composite key on the child side. The eventual existing keys of the child itself are only pseudo or partial-keys, not sufficient to identify any instance of that type of Entity or Entity Set, without the parent's PK.

Non-identifying relationship are the ordinary relations (partial or total), of completely independent entity sets, whose instances do not depend on each others' primary keys to be uniquely identified, although they might need foreign keys for partial or total relationships, but not as the primary key of the child. The child has its own primary key. The parent idem. Both independently. Depending on the cardinality of the relationship, the PK of one goes as a FK to the other (N side), and if partial, can be null, if total, must be not null. But, at a relationship like this, the FK will never be also the PK of the child, as when an identifying relationship is the case.

The proper way to fade a UILabel (or any UIView for that matter) is to use a Core Animation Transition. This will not flicker, nor will it fade to black if the content is unchanged.

A portable and clean solution is to use a Extension in Swift (invoke prior changing visible elements)

// Usage: insert view.fadeTransition right before changing content


extension UIView {
    func fadeTransition(_ duration:CFTimeInterval) {
        let animation = CATransition()
        animation.timingFunction = CAMediaTimingFunction(name:
            CAMediaTimingFunctionName.easeInEaseOut)
        animation.type = CATransitionType.fade
        animation.duration = duration
        layer.add(animation, forKey: CATransitionType.fade.rawValue)
    }
}

Invocation looks like this:

// This will fade
aLabel.fadeTransition(0.4)
aLabel.text = "text"

Prolog predicates 'unify' -

So, in an imperative langauge I'd write

function bazoo(integer foo)
{
   if(foo == 5)
       doSomething();
   else
       doSomeOtherThing();
}

In Prolog I'd write

bazoo(5) :-  doSomething.
bazoo(Foo) :- Foo =/= 5, doSomeOtherThing.

which, when you understand both styles, is actually a lot clearer.
"I'm bazoo for the special case when foo is 5"
"I'm bazoo for the normal case when foo isn't 5"

It is not possible directly. You may as well write some preprocessor which can handle that.

If I understand it correctly then below are the things that can be helpful to achieve that:

• Use a pre-processor which will run through your JS files for example looking for patterns like "@import somefile.js" and replace them with the content of the actual file. Nicholas Zakas(Yahoo) wrote one such library in Java which you can use (http://www.nczonline.net/blog/2009/09/22/introducing-combiner-a-javascriptcss-concatenation-tool/)

• If you are using Ruby on Rails then you can give Jammit asset packaging a try, it uses assets.yml configuration file where you can define your packages which can contain multiple files and then refer them in your actual webpage by the package name.

• Try using a module loader like RequireJS or a script loader like LabJs with the ability to control the loading sequence as well as taking advantage of parallel downloading.

JavaScript currently does not provide a "native" way of including a JavaScript file into another like CSS ( @import ), but all the above mentioned tools/ways can be helpful to achieve the DRY principle you mentioned. I can understand that it may not feel intuitive if you are from a Server-side background but this is the way things are. For front-end developers this problem is typically a "deployment and packaging issue".

Hope it helps.

I like assylias' answer, however I would refactor it as follows:

Sub test()

Dim origNum As String
Dim creditOrDebit As String

origNum = "30062600006"
creditOrDebit = "D"

If creditOrDebit = "D" Then
  If origNum = "006260006" Then
    MsgBox "OK"
  ElseIf origNum = "30062600006" Then
    MsgBox "OK"
  End If
End If

End Sub

This might save you some CPU cycles since if creditOrDebit is <> "D" there is no point in checking the value of origNum.

Update:

I used the following procedure to test my theory that my procedure is faster:

Public Declare Function timeGetTime Lib "winmm.dll" () As Long

Sub DoTests2()

  Dim startTime1 As Long
  Dim endTime1 As Long
  Dim startTime2 As Long
  Dim endTime2 As Long
  Dim i As Long
  Dim msg As String

  Const numberOfLoops As Long = 10000
  Const origNum As String = "006260006"
  Const creditOrDebit As String = "D"

  startTime1 = timeGetTime
  For i = 1 To numberOfLoops
    If creditOrDebit = "D" Then
      If origNum = "006260006" Then
        ' do something here
        Debug.Print "OK"
      ElseIf origNum = "30062600006" Then
        ' do something here
        Debug.Print "OK"
      End If
    End If
  Next i
  endTime1 = timeGetTime

  startTime2 = timeGetTime
  For i = 1 To numberOfLoops
    If (origNum = "006260006" Or origNum = "30062600006") And _
      creditOrDebit = "D" Then
      ' do something here
      Debug.Print "OK"
    End If
  Next i
  endTime2 = timeGetTime

  msg = "number of iterations: " & numberOfLoops & vbNewLine
  msg = msg & "JP proc: " & Format$((endTime1 - startTime1), "#,###") & _
       " ms" & vbNewLine
  msg = msg & "assylias proc: " & Format$((endTime2 - startTime2), "#,###") & _
       " ms"

  MsgBox msg

End Sub

I must have a slow computer because 1,000,000 iterations took nowhere near ~200 ms as with assylias' test. I had to limit the iterations to 10,000 -- hey, I have other things to do :)

After running the above procedure 10 times, my procedure is faster only 20% of the time. However, when it is slower it is only superficially slower. As assylias pointed out, however, when creditOrDebit is <>"D", my procedure is at least twice as fast. I was able to reasonably test it at 100 million iterations.

And that is why I refactored it - to short-circuit the logic so that origNum doesn't need to be evaluated when creditOrDebit <> "D".

At this point, the rest depends on the OP's spreadsheet. If creditOrDebit is likely to equal D, then use assylias' procedure, because it will usually run faster. But if creditOrDebit has a wide range of possible values, and D is not any more likely to be the target value, my procedure will leverage that to prevent needlessly evaluating the other variable.

rownumber() over(...) is working but I didn't like this solution for 2 reasons. - This function is not available when you using older version of SQL like SQL2000 - Dependency on function and is not really readable.

Another solution is:

SELECT tmpall.[OrderNO] ,
       tmpall.[PartCode] ,
       tmpall.[Quantity] ,
FROM   (SELECT [OrderNO],
               [PartCode],
               [Quantity],
               [DateEntered]
        FROM   you_table) AS tmpall
       INNER JOIN (SELECT [OrderNO],
                          Max([DateEntered]) AS _max_date
                   FROM   your_table
                   GROUP  BY OrderNO ) AS tmplast
               ON tmpall.[OrderNO] = tmplast.[OrderNO]
                  AND tmpall.[DateEntered] = tmplast._max_date

The return type of a procedure is int.

You can also return result sets (as your code currently does) (okay, you can also send messages, which are strings)

Those are the only "returns" you can make. Whilst you can add table-valued parameters to a procedure (see BOL), they're input only.

Edit:

(Or as another poster mentioned, you could also use a Table Valued Function, rather than a procedure)

you can give aviation to the view by adding z axis to it and can have default shadow to it. this feature was provided in L preview and will be available after it release. For now you can simply add a image the gives this look for button background

Use try-catch, even if it has an error it will still copy.

Try
   Clipboard.SetText("copy me to clipboard")
Catch ex As Exception

End Try

If you use a message box to capture the exception, it will show you error, but the value is still copied to clipboard.

Pure CSS Workaround:

I was using both bootstrap and jQuery UI and changing the order of adding the scripts broke some other objects. I ended up using pure CSS workaround:

.ui-dialog-titlebar-close {
  background: url("http://code.jquery.com/ui/1.10.3/themes/smoothness/images/ui-icons_888888_256x240.png") repeat scroll -93px -128px rgba(0, 0, 0, 0);
  border: medium none;
}
.ui-dialog-titlebar-close:hover {
  background: url("http://code.jquery.com/ui/1.10.3/themes/smoothness/images/ui-icons_222222_256x240.png") repeat scroll -93px -128px rgba(0, 0, 0, 0);
}

Update: new JsonParser().parse(...) is @deprecated

Based on the javadoc for Gson 2.8.6:

No need to instantiate this class, use the static methods instead.

JsonParser static methods:

JsonParser.parseString?(jsonString);
JsonParser.parseReader?(reader);

Packages:

import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
import com.google.gson.JsonParser;

Example:

private Gson GSON = new GsonBuilder().setPrettyPrinting().create();
public static String getPerfectJSON(String unformattedJSON) {
    String perfectJSON = GSON.toJson(JsonParser.parseString(unformattedJSON));
    return perfectJSON;
}

Google Gson dependency using Maven:

<dependency>
    <groupId>com.google.code.gson</groupId>
    <artifactId>gson</artifactId>
    <version>2.8.6</version>
</dependency>

The problem could be that the Python libraries, per HTTP-Standard, first send an unauthenticated request, and then only if it's answered with a 401 retry, are the correct credentials sent. If the Foursquare servers don't do "totally standard authentication" then the libraries won't work.

Try using headers to do authentication:

import urllib2, base64

request = urllib2.Request("http://api.foursquare.com/v1/user")
base64string = base64.b64encode('%s:%s' % (username, password))
request.add_header("Authorization", "Basic %s" % base64string)   
result = urllib2.urlopen(request)

Had the same problem as you and found the solution from this thread: http://forums.shopify.com/categories/9/posts/27662

You need to tell scp where to send the file. In your command that is not working:

scp C:\Users\Admin\Desktop\WMU\5260\A2.c ~

You have not mentioned a remote server. scp uses : to delimit the host and path, so it thinks you have asked it to download a file at the path \Users\Admin\Desktop\WMU\5260\A2.c from the host C to your local home directory.

The correct upload command, based on your comments, should be something like:

C:\> pscp C:\Users\Admin\Desktop\WMU\5260\A2.c [email protected]:

If you are running the command from your home directory, you can use a relative path:

C:\Users\Admin> pscp Desktop\WMU\5260\A2.c [email protected]:

You can also mention the directory where you want to this folder to be downloaded to at the remote server. i.e by just adding a path to the folder as below:

C:/> pscp C:\Users\Admin\Desktop\WMU\5260\A2.c [email protected]:/home/path_to_the_folder/

The trick is to visit the original page using the 64-bit version of Internet Explorer. The site will then offer you the appropriate download options.

You have two basic options provided by java.util.Collections:

• <T extends Comparable<? super T>> void sort(List<T> list)
  • Use this if T implements Comparable and you're fine with that natural ordering
• <T> void sort(List<T> list, Comparator<? super T> c)
  • Use this if you want to provide your own Comparator.

Depending on what the Collection is, you can also look at SortedSet or SortedMap.

I just want to point out, that there has been a recent addition to the .NET documentation regarding email validation, also utilitzing Regex operations. A thorough explanation to their implementation can be found there.

https://docs.microsoft.com/en-us/dotnet/standard/base-types/how-to-verify-that-strings-are-in-valid-email-format

For convenience, here is a list of their test results:

//       Valid: [email protected]
//       Valid: [email protected]

1. Connection String / Connection Permissions

Check the connection string again.

Make sure the user you are connecting with still has permission to read from [__MigrationHistory] and has permission to edit the schema.

You can also try changing the connection string in the App or Web config file to use Integrated Security (Windows Auth) to run the add-migration command as yourself.

For example:

connectionString="data source=server;initial catalog=db;persist security info=True;Integrated Security=SSPI;" 

This connection string would go in the App.config file of the project where the DbContext is located.

2. StartUp Project

You can specify the StartUp project on the command line or you can right click the project with the DbContext, Configuration and Migrations folder and select Set as StartUp project. I'm serious, this can actually help.

I almost always use curly-braces; however, in some cases where I'm writing tests, I do keyword packing/unpacking, and in these cases dict() is much more maintainable, as I don't need to change:

a=1,
b=2,

to:

'a': 1,
'b': 2,

It also helps in some circumstances where I think I might want to turn it into a namedtuple or class instance at a later time.

In the implementation itself, because of my obsession with optimisation, and when I don't see a particularly huge maintainability benefit, I'll always favour curly-braces.

In tests and the implementation, I would never use dict() if there is a chance that the keys added then, or in the future, would either:

• Not always be a string
• Not only contain digits, ASCII letters and underscores
• Start with an integer (dict(1foo=2) raises a SyntaxError)

So when sending the message to telegram you use:

$token = <Enter Your Token Here>
$url = "https://api.telegram.org/bot".$token;

$chat_id = <The Chat Id Goes Here>;
$test = <Message goes Here>;

//sending Message normally without styling
$response = file_get_content($url."\sendMessage?chat_id=$chat_id&text=$text");

If our message has html tags in it we add "parse_mode" so that our url becomes:

$response = file_get_content($url."\sendMessage?chat_id=$chat_id&text=$text&parse_mode=html")

parse mode can be "HTML" or "markdown"

Set the style on the textbox as text-transform: uppercase?

Just to add more info if you want to format like: HH:mm:ss

0 <= HH <= infinite

0 <= mm < 60

0 <= ss < 60

use this:

int h = (int) ((startTimeInMillis / 1000) / 3600);
int m = (int) (((startTimeInMillis / 1000) / 60) % 60);
int s = (int) ((startTimeInMillis / 1000) % 60);

I just had this issue now and figured this out

SELECT some_cols
FROM prefix_users
WHERE (some conditions)
ORDER BY pic_set DESC, last_activity;

I've come across the same issue after adding the following dependency:

implementation 'com.evernote:android-state:1.4.1'
annotationProcessor 'com.evernote:android-state-processor:1.4.1'

And the reason was that latest version of evernote uses dependencies to AndroidX, while I had support library version 27.1.1 in my project. So there was an option of upgrading support libraries to 28.0.0, as the other answers suggest, but that was a bit tricky for a large project with lots of custom views. So, I resolved the issue by downgrading evernote version to 1.3.1.

boolean isEquals(List<String> firstList, List<String> secondList){
    ArrayList<String> commons = new ArrayList<>();

    for (String s2 : secondList) {
        for (String s1 : firstList) {
           if(s2.contains(s1)){
               commons.add(s2);
           }
        }
    }

    firstList.removeAll(commons);
    secondList.removeAll(commons);
    return !(firstList.size() > 0 || secondList.size() > 0) ;
}

If you want to use this answer, I found out that when you are using MacDown on MacOs, you can <div style="text-align: justify"> at the beginning of the document to justify all text and keep all code formating. Maybe it works on other editors too, for you to try ;)

If the variable ax.xaxis._autolabelpos = True, matplotlib sets the label position in function _update_label_position in axis.py according to (some excerpts):

    bboxes, bboxes2 = self._get_tick_bboxes(ticks_to_draw, renderer)
    bbox = mtransforms.Bbox.union(bboxes)
    bottom = bbox.y0
    x, y = self.label.get_position()
    self.label.set_position((x, bottom - self.labelpad * self.figure.dpi / 72.0))

You can set the label position independently of the ticks by using:

    ax.xaxis.set_label_coords(x0, y0)

that sets _autolabelpos to False or as mentioned above by changing the labelpad parameter.

EDIT: first try the new pip method:

Windows: pip3 install opencv-python opencv-contrib-python

Ubuntu: sudo apt install python3-opencv

or continue below for build instructions

Note: The original question was asking for OpenCV + Python 3.3 + Windows. Since then, Python 3.5 has been released. In addition, I use Ubuntu for most development so this answer will focus on that setup, unfortunately

OpenCV 3.1.0 + Python 3.5.2 + Ubuntu 16.04 is possible! Here's how.

These steps are copied (and slightly modified) from:

• http://docs.opencv.org/3.1.0/d7/d9f/tutorial_linux_install.html
• https://opencv-python-tutroals.readthedocs.io/en/latest/py_tutorials/py_setup/py_setup_in_fedora/py_setup_in_fedora.html#install-opencv-python-in-fedora

Prerequisites

Install the required dependencies and optionally install/update some libraries on your system:

# Required dependencies
sudo apt install build-essential cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
# Dependencies for Python bindings
# If you use a non-system copy of Python (eg. with pyenv or virtualenv), then you probably don't need to do this part
sudo apt install python3.5-dev libpython3-dev python3-numpy
# Optional, but installing these will ensure you have the latest versions compiled with OpenCV
sudo apt install libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev

Building OpenCV

CMake Flags

There are several flags and options to tweak your build of OpenCV. There might be comprehensive documentation about them, but here are some interesting flags that may be of use. They should be included in the cmake command:

# Builds in TBB, a threading library
-D WITH_TBB=ON
# Builds in Eigen, a linear algebra library
-D WITH_EIGEN=ON

Using non-system level Python versions

If you have multiple versions of Python (eg. from using pyenv or virtualenv), then you may want to build against a certain Python version. By default OpenCV will build for the system's version of Python. You can change this by adding these arguments to the cmake command seen later in the script. Actual values will depend on your setup. I use pyenv:

-D PYTHON_DEFAULT_EXECUTABLE=$HOME/.pyenv/versions/3.5.2/bin/python3.5
-D PYTHON_INCLUDE_DIRS=$HOME/.pyenv/versions/3.5.2/include/python3.5m
-D PYTHON_EXECUTABLE=$HOME/.pyenv/versions/3.5.2/bin/python3.5
-D PYTHON_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython3.5m.so.1

CMake Python error messages

The CMakeLists file will try to detect various versions of Python to build for. If you've got different versions here, it might get confused. The above arguments may only "fix" the issue for one version of Python but not the other. If you only care about that specific version, then there's nothing else to worry about.

This is the case for me so unfortunately, I haven't looked into how to resolve the issues with other Python versions.

Install script

# Clone OpenCV somewhere
# I'll put it into $HOME/code/opencv
OPENCV_DIR="$HOME/code/opencv"
OPENCV_VER="3.1.0"
git clone https://github.com/opencv/opencv "$OPENCV_DIR"
# This'll take a while...

# Now lets checkout the specific version we want
cd "$OPENCV_DIR"
git checkout "$OPENCV_VER"

# First OpenCV will generate the files needed to do the actual build.
# We'll put them in an output directory, in this case "release"
mkdir release
cd release

# Note: This is where you'd add build options, like TBB support or custom Python versions. See above sections.
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local "$OPENCV_DIR"

# At this point, take a look at the console output.
# OpenCV will print a report of modules and features that it can and can't support based on your system and installed libraries.
# The key here is to make sure it's not missing anything you'll need!
# If something's missing, then you'll need to install those dependencies and rerun the cmake command.

# OK, lets actually build this thing!
# Note: You can use the "make -jN" command, which will run N parallel jobs to speed up your build. Set N to whatever your machine can handle (usually <= the number of concurrent threads your CPU can run).
make
# This will also take a while...

# Now install the binaries!
sudo make install

By default, the install script will put the Python bindings in some system location, even if you've specified a custom version of Python to use. The fix is simple: Put a symlink to the bindings in your local site-packages:

ln -s /usr/local/lib/python3.5/site-packages/cv2.cpython-35m-x86_64-linux-gnu.so $HOME/.pyenv/versions/3.5.2/lib/python3.5/site-packages/

The first path will depend on the Python version you setup to build. The second depends on where your custom version of Python is located.

Test it!

OK lets try it out!

For that, you need to update the redis configuration file.By default, there is no any password for redis.

01) open redis configuration file

sudo vi /etc/redis/redis.conf

find requirepass field under SECURITY section and uncomment that field.Then set your password instead of "foobared"

# requirepass foobared

It should be like,

requirepass YOUR_PASSWORD

Then restart redis and start redis-cli.

If you need to check whether you have set the password correctly, you can run below commads in redis-cli.

To include an external Javascript file you use the <script> tag. The src attribute points to the location of your Javascript file within your web project.

<script src="some.js" type="text/javascript"></script>

JQuery is simply a Javascript file, so if you download a copy of the file you can include it within your page using a script tag. You can also include Jquery from a content distribution network such as the one hosted by Google.

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>

Yes, some how the ajax call aborted. The cause may be following.

1. Before completion of ajax request, user navigated to other page.
2. Ajax request have timeout.
3. Server is not able to return any response.

My approach would not be to start by writing your own API. Life's too short, and there are more pressing problems to solve. In this situation, I typically:

• Find a library that appears to do what I want. If one doesn't exist, then implement it.
• If a library does exist, but I'm not sure it'll be suitable for my needs, write a thin adapter API around it, so I can control how it's called. The adapter API expresses the API I need, and it maps those calls to the underlying API.
• If the library doesn't turn out to be suitable, I can swap another one in underneath the adapter API (whether it's another open source one or something I write myself) with a minimum of effort, without affecting the callers.

Start with something someone has already written. Odds are, it'll do what you want. You can always write your own later, if necessary. OpenCSV is as good a starting point as any.

if location == a2:
    img = Image.open("picture.jpg")
    Img.show

Make sure the name of the image is in parantheses this should work

If you're not familiar or comfortable with is(), you could just check the value of prop("selected").

As seen here:

$('#mySelectBox option').each(function() {
    if ($(this).prop("selected") == true) {
       // do something
    } else {
       // do something
    }
});?

Edit:

As @gdoron pointed out in the comments, the faster and most appropriate way to access the selected property of an option is via the DOM selector. Here is the fiddle update displaying this action.

if (this.selected == true) {

appears to work just as well! Thanks gdoron.

It happened to me that I had an instance of the packager running with an old project (I ran react-native start as usual). I was using Ubuntu 14.04. So what I did was to stop that instance and go to my project folder and in two different console tabs I ran these two commands separately:

npm start #here I used to run react-native start
react-native run-android

npm start is defined in my package.json as:

"start": "node_modules/react-native/packager/packager.sh"

I don't know if there is a sort of confusing stuff for react-native but that did the trick.

Try this, it works!

<div class="row">
    <div class="center">
        <div class="col-xs-12 col-sm-4">
            <p>hi 1!</p>
        </div>
        <div class="col-xs-12 col-sm-4">
            <p>hi 2!</p>
        </div>
        <div class="col-xs-12 col-sm-4">
            <p>hi 3!</p>
        </div>
    </div>
</div>

Then, in css define the width of center div and center in a document:

.center {
    margin: 0 auto;
    width: 80%;
}

If you editing info.plist directly, below should help you, don't key in "YES" as string below:

<key>UIFileSharingEnabled</key>
<string>YES</string>

You should use this:

<key>UIFileSharingEnabled</key>
<true/>

As of Jackson 1.6, you can use:

I know this is a bit late but what I did to our application is this. Hope this will help someone tho. But it works for me:

One of the pitfalls as I know is IE problem with custom elements. As quoted from the docs:

3) you do not use custom element tags such as (use the attribute version instead)

4) if you do use custom element tags, then you must take these steps to make IE 8 and below happy

<!doctype html>
  <html xmlns:ng="http://angularjs.org" id="ng-app" ng-app="optionalModuleName">

Double pipe stands for logical "OR". This is not really the case when the "parameter not set", since strictly in the javascript if you have code like this:

function foo(par) {
}

Then calls

foo()
foo("")
foo(null)
foo(undefined)
foo(0)

are not equivalent.

Double pipe (||) will cast the first argument to boolean and if resulting boolean is true - do the assignment otherwise it will assign the right part.

This matters if you check for unset parameter.

Let's say, we have a function setSalary that has one optional parameter. If user does not supply the parameter then the default value of 10 should be used.

if you do the check like this:

function setSalary(dollars) {
    salary = dollars || 10
}

This will give unexpected result on call like

setSalary(0) 

It will still set the 10 following the flow described above.

Have you tried HttpServerUtility.UrlDecode or HttpUtility.UrlDecode?

I wrote a mixin for some syntactic sugar ;)
Maybe someone likes this way of writing if-then-else better than using guards

depends on Less 1.7.0

https://github.com/pixelass/more-or-less/blob/master/less/fn/_if.less

Usage:

.if(isnumber(2), {
    .-then(){
        log {
            isnumber: true;
        }
    }
    .-else(){
        log {
            isnumber: false;
        }
    }
});

.if(lightness(#fff) gt (20% * 2), {
    .-then(){
        log {
            is-light: true;
        }
    }
});

using on example from above

.if(@debug, {
    .-then(){
        header {
            background-color: yellow;
            #title {
                background-color: orange;
            }
        }
        article {
            background-color: red;
        }
    }
});

you can simply use,

var className = $('#id').attr('class');

Using jQuery it's quite trivial. v2.0 uses the table class on all tables.

$('.table > tbody > tr').click(function() {
    // row was clicked
});

Once a thread is started, it is not necessary to retain a reference to the Thread object. The thread continues to execute until the thread procedure ends.

new Thread(new ThreadStart(SecondFoo)).Start();

Set decoding to true

Your decoding is not set to true. If you don't have access to set the source to true. The code below will fix it for you.

$WorkingArray = json_decode(json_encode($data),true);

Jan 2020 Update

@Flimm has explained all the differences very well. Generally, we want to know the difference between all tools because we want to decide what's best for us. So, the next question would be: which one to use? I suggest you choose one of the two official ways to manage virtual environments:

• Python Packaging now recommends Pipenv
• Python.org now recommends venv

This is actually a documented feature, and can be found here

// This event listener calls addMarker() when the map is clicked.
  google.maps.event.addListener(map, 'click', function(e) {
    placeMarker(e.latLng, map);
  });

  function placeMarker(position, map) {
    var marker = new google.maps.Marker({
      position: position,
      map: map
    });  
    map.panTo(position);
  }

try this one : java.net.URL;
JOptionPane.showMessageDialog(null, getDomainName(new URL("https://en.wikipedia.org/wiki/List_of_Internet_top-level_domains")));

public String getDomainName(URL url){
String strDomain;
String[] strhost = url.getHost().split(Pattern.quote("."));
String[] strTLD = {"com","org","net","int","edu","gov","mil","arpa"};

if(Arrays.asList(strTLD).indexOf(strhost[strhost.length-1])>=0)
    strDomain = strhost[strhost.length-2]+"."+strhost[strhost.length-1];
else if(strhost.length>2)
    strDomain = strhost[strhost.length-3]+"."+strhost[strhost.length-2]+"."+strhost[strhost.length-1];
else
    strDomain = strhost[strhost.length-2]+"."+strhost[strhost.length-1];
return strDomain;}

I think Alt+R+F is the correct one for creating property from a variable declaration

If you're trying to test existing code that you're reluctant or unable to change, reflection is a good choice.

If the class's design is still flexible, and you've got a complicated private method that you'd like to test separately, I suggest you pull it out into a separate class and test that class separately. This doesn't have to change the public interface of the original class; it can internally create an instance of the helper class and call the helper method.

If you want to test difficult error conditions coming from the helper method, you can go a step further. Extract an interface from the helper class, add a public getter and setter to the original class to inject the helper class (used through its interface), and then inject a mock version of the helper class into the original class to test how the original class responds to exceptions from the helper. This approach is also helpful if you want to test the original class without also testing the helper class.

There are a couple of libraries out there. onnov/detect-encoding looks promising. It claims to do better than mb_detect_encoding

Example usage for converting string in unknown character encoding to UTF-8:

use Onnov\DetectEncoding\EncodingDetector;
$detector->iconvXtoEncoding('??????????? ?????')

To simply detect encoding:

$encoding = $detector->getEncoding('??????????? ?????');

My understanding is driver.close(); will close the current browser, and driver.quit(); will terminate all the browser that.

The <textarea> element automatically aligns text at the top of a textbox, if you don't want to use CSS to force it.

You can use the runOnUiThread() method as follows. If you're not using a ListActivity, just adapt the code to get a reference to your ArrayAdapter.

final ArrayAdapter adapter = ((ArrayAdapter)getListAdapter());
runOnUiThread(new Runnable() {
    public void run() {
        adapter.notifyDataSetChanged();
    }
});

In your example number is a primitive, so will be stored as a value.

If you want to use a reference then you should use one of the wrapper types (e.g. Integer)

If it's available to you, then it's difficult to think of a reason not to use the Java 5 executor framework. Calling:

ScheduledExecutorService ex = Executors.newSingleThreadScheduledExecutor();

will give you a ScheduledExecutorService with similar functionality to Timer (i.e. it will be single-threaded) but whose access may be slightly more scalable (under the hood, it uses concurrent structures rather than complete synchronization as with the Timer class). Using a ScheduledExecutorService also gives you advantages such as:

• You can customize it if need be (see the newScheduledThreadPoolExecutor() or the ScheduledThreadPoolExecutor class)
• The 'one off' executions can return results

About the only reasons for sticking to Timer I can think of are:

• It is available pre Java 5
• A similar class is provided in J2ME, which could make porting your application easier (but it wouldn't be terribly difficult to add a common layer of abstraction in this case)

There are several ways to UPDATE using sqlalchemy

1) for c in session.query(Stuff).all():
       c.foo += 1
   session.commit()

2) session.query().\
       update({"foo": (Stuff.foo + 1)})
   session.commit()

3) conn = engine.connect()
   stmt = Stuff.update().\
       values(Stuff.foo = (Stuff.foo + 1))
   conn.execute(stmt)

After Playing around a bit I came up with this and it seems to work just splendidly

<select name="options[]" id="options" class="form-control" multiple>
    @foreach($settings->includes->get('optionList') as $option)
        <option value="{{ $option->id }}" {{ (collect(old('options'))->contains($option->id)) ? 'selected':'' }}>{{ $option->name }}</option>
    @endforeach
</select>

I may be 100% wrong in leveraging the collect function but it works fine on many of my tests. After seeing a few other posts on the site I saw someone recommend leveraging the in_array($needle, $array) function but after noticing that if my old('options') was null it would error out because it requires in_array requires, bet you guessed an array. So after finding the solution to that albeit ugly solution I played with the collect method because after all we are using larval right! well anyway the ugly solution is as follows

@if (old("options")){{ (in_array($option->id, old("options")) ? "selected":"") }}@endif

inline but man that looks ugly to me so long story short I am using the following instead

{{ (collect(old('options'))->contains($option->id)) ? 'selected':'' }}

Hope this helps others!!

This does not seem to work for a non multiple select field ill get back with one that does work for that though.

Clear = Button(root,text="Clear",command=clear).pack()                       

Input is set the textvariable in the entry, which is the string variable and when I set the text of the string variable as "" this clears the text in the entry

printf '%b' "-123\nABC" | tr '[:space:]' '_' | grep -q '^-\?[[:digit:]]\+$' && echo "Integer." || echo "NOT integer."

Remove the -\? in grep matching pattern if you don't accept negative integer.

DAYS360 does not calculate what you want, i.e. the number of days passed between the two dates. Use simple subtraction (-) or MINUS(). I made an updated copy of @DrCord’s sample spreadsheet to illustrate this.

Are you SURE you want DAYS360? That is a specialized function used in the financial sector to simplify calculations for bonds. It assumes a 360 day year, with 12 months of 30 days each. If you really want actual days, you'll lose 6 days each year. [source]

So you didn't say you wanted the application to quit or exit abruptly, so as another option, perhaps just have the response loop end out elegantly. (I am assuming you have a while loop waiting for user instructions. This is some code from a project I just wrote today.

        Console.WriteLine("College File Processor");
        Console.WriteLine("*************************************");
        Console.WriteLine("(H)elp");
        Console.WriteLine("Process (W)orkouts");
        Console.WriteLine("Process (I)nterviews");
        Console.WriteLine("Process (P)ro Days");
        Console.WriteLine("(S)tart Processing");
        Console.WriteLine("E(x)it");
        Console.WriteLine("*************************************");

        string response = "";
        string videotype = "";
        bool starting = false;
        bool exiting = false;

        response = Console.ReadLine();

        while ( response != "" )
        {
            switch ( response  )
            {
                case "H":
                case "h":

                        Console.WriteLine("Please Select Video Type Before Starting");
                    }

            if ( starting || exiting)
            {
                break;
            }
            else
            {
                response = Console.ReadLine();
            }

Native tooltip cannot be styled.

That being said, you can use some library that would show styles floating layers when element is being hovered (instead of the native tooltips, and suppress them) requiring little or no code modifications...

try this one: http://www.applied-mathematics.net/tools/xmlParser.html
it's easier and faster than RapidXML or PUGXML.
TinyXML is the worst of the "simple parser".

Try this

rm -rf /usr/local/var/mysql && brew postinstall [email protected] && brew services restart [email protected]

As above the question was originally about MySQL

Use REGEXP, not LIKE:

SELECT * FROM `table` WHERE ([url] NOT REGEXP '^[-A-Za-z0-9/.]+$')

In my case, it was oursql that was causing the same(generic) error as below.

In file included from oursqlx/oursql.c:236:0:
  oursqlx/compat.h:13:19: fatal error: mysql.h: No such file or directory
  compilation terminated.
  error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

  ----------------------------------------
  Failed building wheel for oursql
  Running setup.py clean for oursql

So, I knew that I need to have libmysqlcppconn-dev package.

sudo apt-get install libmysqlcppconn-dev

And all good!

What worked for me was adding a div around the content. Originally i had this. Css applied to the td had no effect.

        <td>           
             @Html.DisplayFor(modelItem => item.Message)           
        </td>

Then I wrapped the content in a div and the css worked as expected

       <td>
            <div class="largeContent">
                @Html.DisplayFor(modelItem => item.Message)
            </div>
        </td>

In my case "el-ri-1.0.jar" was missing.

You can try following way

<input type= "file" name="Upload" accept = "application/pdf,.csv, application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, application/vnd.ms-excel">

OR (in asp.net mvc)

@Html.TextBoxFor(x => x.FileName, new { @id = "doc", @type = "file", @accept = "application/pdf,.csv, application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, application/vnd.ms-excel" })

Table elements don't appear to support this directly. Place the table in a div and set the height of the div and set overflow: auto.

This is SUPER late and probably not relevant anymore, but if anyone stumbles upon this answer, I believe I know the cause.

So the JSON encoded string is perfectly valid with the degree symbol in it, as the other answer mentions. The problem is most likely in the character encoding that you are reading/writing with. Depending on how you are using Gson, you are probably passing it a java.io.Reader instance. Any time you are creating a Reader from an InputStream, you need to specify the character encoding, or java.nio.charset.Charset instance (it's usually best to use java.nio.charset.StandardCharsets.UTF_8). If you don't specify a Charset, Java will use your platform default encoding, which on Windows is usually CP-1252.

As your list is an ArrayList, it can be assumed that it is unsorted. Therefore, there is no way to search for your element that is faster than O(n).

If you can, you should think about changing your list into a Set (with HashSet as implementation) with a specific Comparator for your sample class.

Another possibility would be to use a HashMap. You can add your data as Sample (please start class names with an uppercase letter) and use the string you want to search for as key. Then you could simply use

Sample samp = myMap.get(myKey);

If there can be multiple samples per key, use Map<String, List<Sample>>, otherwise use Map<String, Sample>. If you use multiple keys, you will have to create multiple maps that hold the same dataset. As they all point to the same objects, space shouldn't be that much of a problem.

I had the same problem. I fixed it by adding this piece of code inside the text area's style.

resize: vertical;

You can check the Bootstrap reference here

JSONObject params = new JSONObject();
try {
   params.put(key, val);
}catch (JSONException e){
   e.printStackTrace();
}

this is how i pass "params"(JSONObject) through POST

connection.getOutputStream().write(params.toString().getBytes("UTF-8"));

To plot just a selection of your columns you can select the columns of interest by passing a list to the subscript operator:

ax = df[['V1','V2']].plot(kind='bar', title ="V comp", figsize=(15, 10), legend=True, fontsize=12)

What you tried was df['V1','V2'] this will raise a KeyError as correctly no column exists with that label, although it looks funny at first you have to consider that your are passing a list hence the double square brackets [[]].

import matplotlib.pyplot as plt
ax = df[['V1','V2']].plot(kind='bar', title ="V comp", figsize=(15, 10), legend=True, fontsize=12)
ax.set_xlabel("Hour", fontsize=12)
ax.set_ylabel("V", fontsize=12)
plt.show()

I prefer to use ToString() and IFormatProvider.

double value = 100000.3
Console.WriteLine(value.ToString("0,0.00", new CultureInfo("en-US", false)));

Output: 10,000.30

x if y else z is the syntax for the expression you're returning for each element. Thus you need:

[ x if x%2 else x*100 for x in range(1, 10) ]

The confusion arises from the fact you're using a filter in the first example, but not in the second. In the second example you're only mapping each value to another, using a ternary-operator expression.

With a filter, you need:

[ EXP for x in seq if COND ]

Without a filter you need:

[ EXP for x in seq ]

and in your second example, the expression is a "complex" one, which happens to involve an if-else.

You also can use in this form:

<a href="@Url.Action("Information", "Admin", null)"> Admin</a>

If you have them already in a byte[] array, you can use:

int result = ByteBuffer.wrap(bytes).getInt();

request.getSession() will return a current session. if current session does not exist, then it will create a new one.

request.getSession(true) will return current session. If current session does not exist, then it will create a new session.

So basically there is not difference between both method.

request.getSession(false) will return current session if current session exists. If not, it will not create a new session.

This is my solution with prepared statements and stored procedure is returning several rows not only one value.

<?php

require 'config.php';
header('Content-type:application/json');
$connection->set_charset('utf8');

$mIds = $_GET['ids'];

$stmt = $connection->prepare("CALL sp_takes_string_returns_table(?)");
$stmt->bind_param("s", $mIds);

$stmt->execute();

$result = $stmt->get_result();
$response = $result->fetch_all(MYSQLI_ASSOC);
echo json_encode($response);

$stmt->close();
$connection->close();

Delete the unit testing from your project follow the below steps this will solve the issue.

select your project from the project navigator to open the project editor. From the target delete the test from the left side of the project editor and press the Delete key.

I was looking for a solution for this same problem, to create a list of logos.

I came up with this solution that uses a bit of flexbox, which works for us since we're not worried about old browsers.

This example assumes a 100x100px box but I'm pretty sure the size could be flexible/responsive.

.img__container {
    display: flex;
    padding: 15px 12px;
    box-sizing: border-box;
    width: 100px; height: 100px;

    img {
        margin: auto;
        max-width: 100%;
        max-height: 100%;
    }
}

ps.: you may need to add some prefixes or use autoprefixer.

For reference, here is a minimal implementation using Java 8 :

@Override
public void start(Stage mainStage) throws Exception {

    Scene scene = new Scene(new Region());
    mainStage.setWidth(640);
    mainStage.setHeight(480);
    mainStage.setScene(scene);

    //this makes all stages close and the app exit when the main stage is closed
    mainStage.setOnCloseRequest(e -> Platform.exit());

    //add real stuff to the scene...
    //open secondary stages... etc...
}

Use <f:convertDateTime>. You can nest this in any input and output component. Pattern rules are same as java.text.SimpleDateFormat.

<h:outputText value="#{someBean.dateField}" >
    <f:convertDateTime pattern="dd.MM.yyyy HH:mm" />
</h:outputText>

Thanks a lot it worked , please note I did a typo in php as it should be mysqli_query( $con2, $sql )

This is a very highly upvoted issue request in Github for Floating Windows.

Until they support it, you can try the following workarounds:

1. Duplicate Workspace in New Window ^[1]

The Duplicate Workspace in new Window Command was added in v1.24 (May 2018) to sort of address this.

1. Open up Keyboard Shortcuts Ctrl + K, Ctrl + S
2. Map workbench.action.duplicateWorkspaceInNewWindow to Ctrl + Shift + N or whatever you'd like

2. Open Active File in New Window ^[2]

Rather than manually open a new window and dragging the file, you can do it all with a single command.

1. Open Active File in New Window Ctrl + K, O

3. New Window with Same File ^[3]

As AllenBooTung also pointed out, you can open/drag any file in a separate blank instance.

1. Open New Window Ctrl + Shift + N
2. Drag tab into new window

4. Open Workspace and Folder Simultaneously ^[4]

VS Code will not allow you to open the same folder in two different instances, but you can use Workspaces to open the same directory of files in a side by side instance.

1. Open Folder Ctrl + K,Ctrl + O
2. Save Current Project As a Workspace
3. Open Folder Ctrl + K,Ctrl + O

For any workaround, also consider setting setting up auto save so the documents are kept in sync by updating the files.autoSave setting to afterDelay, onFocusChange, or onWindowChange

If you want to force-run a single specific directory or daemon's log files, you can usually find the configuration in /etc/logrotate.d, and they will work standalone.

Keep in mind that global configuration specified in /etc/logrotate.conf will not apply, so if you do this you should ensure you specify all the options you want in the /etc/logrotate.d/[servicename] config file specifically.

You can try it out with -d to see what would happen:

logrotate -df /etc/logrotate.d/nginx

Then you can run (using nginx as an example):

logrotate -f /etc/logrotate.d/nginx

And the nginx logs alone will be rotated.

Considering that you already have a full backup I’d just restore that backup into separate database and migrate the data from there.

If your data has changed after the latest backup then what you recover all data that way but you can try to recover that by reading transaction log.

If your database was in full recovery mode than transaction log has enough details to recover updates to your data after the latest backup.

You might want to try with DBCC LOG, fn_log functions or with third party log reader such as ApexSQL Log

Unfortunately there is no easy way to read transaction log because MS doesn’t provide documentation for this and stores the data in its proprietary format.

You can also set the color individually for each point/bar if you change the data array to be configuration objects instead of numbers.

data: [
      {y: 34.4, color: 'red'},     // this point is red
      21.8,                        // default blue
      {y: 20.1, color: '#aaff99'}, // this will be greenish
      20]                          // default blue

Example on jsfiddle

$("#h273yrjdfhgsfyiruwyiywer").children('[value="' + i + '"]').prop("selected", true);

max(stats, key=stats.get)

Use the wc utility with the print the byte counts (-c) option:

$ SO="stackoverflow"
$ echo -n "$SO" | wc -c
    13

You'll have to use the do not output the trailing newline (-n) option for echo. Otherwise, the newline character will also be counted.

Simple version here What is a general function for JavaScript trim?

function trim(str) {
        return str.replace(/^\s+|\s+$/g,"");
}

Any solution to this problem boils down to a shared secret. I also don't like the hard-coded user-name and password option but it does have the benefit of being quite simple. The client certificate is also good but is it really much different? There's a cert on the server and one on the client. It's main advantage is that it's harder to brute force. Hopefully you've got other protections in place to protect against that though.

I don't think your point A for the client certificate solution is difficult to resolve. You just use a branch. if (client side certificat) { check it } else { http basic auth } I'm no java expert and I've never worked with it to do client side certificates. However a quick Google leads us to this tutorial which looks right up your alley.

Despite all of this "what's best" discussion, let me just point out that there is another philosophy that says, "less code, less cleverness is better." (I personally hold this philosophy). The client certificate solution sounds like a lot of code.

I know you expressed questions about OAuth, but the OAuth2 proposal does include a solution to your problem called "bearer tokens" which must be used in conjunction with SSL. I think, for the sake of simplicity, I'd choose either the hard-coded user/pass (one per app so that they can be revoked individually) or the very similar bearer tokens.

Type-check with the -is operator returns false for any null value. In most cases, if not all, $value -is [System.Object] will be true for any possible non-null value. (In all cases, it will be false for any null-value.)

My value is nothing if not an object.

firstly you need to import the Select class and then you need to create the instance of Select class. After creating the instance of Select class, you can perform select methods on that instance to select the options from dropdown list. Here is the code

from selenium.webdriver.support.select import Select

select_fr = Select(driver.find_element_by_id("fruits01"))
select_fr.select_by_index(0)

Global die() function for development purposes:

var die = function(msg) {
    throw new Error(msg);
}

Use die():

die('Error message here');

if you have child elements like dropdown menus

$('html').click(function(e) {
  //if clicked element is not your element and parents aren't your div
  if (e.target.id != 'your-div-id' && $(e.target).parents('#your-div-id').length == 0) {
    //do stuff
  }
});

I have had this exact issue for almost 2 weeks, extremely frustrating but I FINALLY found this site and it was a clear walk-through of what to do.

I hope this helps people because it was exactly what I was looking for

Elegant way

In my humble opinion the most elegant way to encode query params is to create an object with params like

const queryParams = { param1: 'value1', param2: 'value2' }

and then encode it using:

const queryString = new URLSearchParams(queryParams).toString()

as mentioned in this answer: https://stackoverflow.com/a/53171438/7284582

Check out the moment.js library. It works with browsers as well as with Node.JS. Allows you to write

moment().hour();

or

moment().hours();

without prior writing of any functions.

Something like this...

var res = from row in myDTable.AsEnumerable()
where row.Field<int>("EmpID") == 5 &&
(row.Field<string>("EmpName") != "abc" ||
row.Field<string>("EmpName") != "xyz")
select row;

Complementing the above answers and also "Parroting" from the Windows Dev Center documentation,

The Winsock2.h header file internally includes core elements from the Windows.h header file, so there is not usually an #include line for the Windows.h header file in Winsock applications. If an #include line is needed for the Windows.h header file, this should be preceded with the #define WIN32_LEAN_AND_MEAN macro. For historical reasons, the Windows.h header defaults to including the Winsock.h header file for Windows Sockets 1.1. The declarations in the Winsock.h header file will conflict with the declarations in the Winsock2.h header file required by Windows Sockets 2.0. The WIN32_LEAN_AND_MEAN macro prevents the Winsock.h from being included by the Windows.h header ..

instead of

document.getElementById("txtBillingGroupName").value = groupName;

You can use

$("#txtBillingGroupName").val(groupName);

instead of groupName you can pass string value like "Group1"

The best solution is to set the checked or unchecked state (either from client or server) and to not let the user change it after wards (i.e make it readonly) do the following:

<input type="radio" name="name" onclick="javascript: return false;" />
