I know this is an older post, but it helped me out. I've also found that for bootstrap v4 you can also change the arrow color by overriding the controls like this:

.carousel-control-prev-icon {
 background-image: url("data:image/svg+xml;charset=utf8,%3Csvg xmlns='http://www.w3.org/2000/svg' fill='%23fff' viewBox='0 0 8 8'%3E%3Cpath d='M5.25 0l-4 4 4 4 1.5-1.5-2.5-2.5 2.5-2.5-1.5-1.5z'/%3E%3C/svg%3E") !important;
}

.carousel-control-next-icon {
  background-image: url("data:image/svg+xml;charset=utf8,%3Csvg xmlns='http://www.w3.org/2000/svg' fill='%23fff' viewBox='0 0 8 8'%3E%3Cpath d='M2.75 0l-1.5 1.5 2.5 2.5-2.5 2.5 1.5 1.5 4-4-4-4z'/%3E%3C/svg%3E") !important;
}

Where you change fill='%23fff' the fff at the end to any hexadecimal value that you want. For example:

fill='%23000' for black, fill='%23ff0000' for red and so on. Just a note, I haven't tested this without the !important declaration.

Try this

Get-ChildItem  | % { Write-Host "$($_.FullName)\$buildConfig\$($_.Name).dll" }

In your code,

1. $build-Config is not a valid variable name.
2. $.FullName should be $_.FullName
3. $ should be $_.Name

You have most of the code…

CURLOPT_HTTPHEADER for curl_setopt() takes an array with each header as an element. You have one element with multiple headers.

You also need to add the Authorization header to your $header array.

$header = array();
$header[] = 'Content-length: 0';
$header[] = 'Content-type: application/json';
$header[] = 'Authorization: OAuth SomeHugeOAuthaccess_tokenThatIReceivedAsAString';

Why not just use the else ?

if (child is IContainer)
{
  //
}
else
{
  // Do what you want here
}

Its neat it familiar and simple ?

My 2 cents:

    using (ZipArchive archive = ZipFile.Open(zFile, ZipArchiveMode.Create))
    {
        foreach (var fPath in filePaths)
        {
            archive.CreateEntryFromFile(fPath,Path.GetFileName(fPath));
        }
    }

So Zip files could be created directly from files/dirs.

Try this

String mess = getResources().getString(R.string.mess_1);

UPDATE

String string = getString(R.string.hello);

You can use either getString(int) or getText(int) to retrieve a string. getText(int) will retain any rich text styling applied to the string.

Reference: https://developer.android.com/guide/topics/resources/string-resource.html

The way the operator works is that it gets incremented at the same time, but if it is before a variable, the expression will evaluate with the incremented/decremented variable:

int x = 0;   //x is 0
int y = ++x; //x is 1 and y is 1

If it is after the variable the current statement will get executed with the original variable, as if it had not yet been incremented/decremented:

int x = 0;   //x is 0
int y = x++; //'y = x' is evaluated with x=0, but x is still incremented. So, x is 1, but y is 0

I agree with dcp in using pre-increment/decrement (++x) unless necessary. Really the only time I use the post-increment/decrement is in while loops or loops of that sort. These loops are the same:

while (x < 5)  //evaluates conditional statement
{
    //some code
    ++x;       //increments x
}

or

while (x++ < 5) //evaluates conditional statement with x value before increment, and x is incremented
{
    //some code
}

You can also do this while indexing arrays and such:

int i = 0;
int[] MyArray = new int[2];
MyArray[i++] = 1234; //sets array at index 0 to '1234' and i is incremented
MyArray[i] = 5678;   //sets array at index 1 to '5678'
int temp = MyArray[--i]; //temp is 1234 (becasue of pre-decrement);

Etc, etc...

This is one of option where we can pass the column names to the dataframe while loading CSV.

import pandas
    names = ['sepal-length', 'sepal-width', 'petal-length', 'petal-width', 'class']
    dataset = pandas.read_csv("C:/Users/NS00606317/Downloads/Iris.csv", names=names, header=0)
print(dataset.head(10))

Output

    sepal-length  sepal-width  petal-length  petal-width        class

You could execute the .sql file as a script in the SQL Developer worksheet. Either use the Run Script icon, or simply press F5.

For example,

@path\script.sql;

Remember, you need to put @ as shown above.

But, if you have exported the database using database export utility of SQL Developer, then you should use the Import utility. Follow the steps mentioned here Importing and Exporting using the Oracle SQL Developer 3.0

Try this,

IFS=''
while read line
do
    echo $line
done < file.txt

EDIT:

From man bash

IFS - The Internal Field Separator that is used for word
splitting after expansion and to split lines into words
with  the  read  builtin  command. The default value is
``<space><tab><newline>''

You can use itertools.count() to generate unbounded sequences. (itertools is in the Python standard library). Docs here:
https://docs.python.org/3/library/itertools.html#itertools.count

To find length of an array A you should use the length property. It is as A.length, do not use A.length() its mainly used for size of string related objects.

The length property will always show the total allocated space to the array during initialization.

If you ever have any of these kind of problems the simple way is to run it. Happy Programming!

If you do truly want the IP assigned to your emulator:

adb shell
ifconfig eth0

Which will give you something like:

eth0: ip 10.0.2.15 mask 255.255.255.0 flags [up broadcast running multicast]

The first argument to a shell script is available as the variable $1, so the simplest implementation would be

if [ "$1" == "-h" ]; then
  echo "Usage: `basename $0` [somestuff]"
  exit 0
fi

But what anubhava said.

Another way to create an array with String apart from

String[] strings =  { "abc", "def", "hij", "xyz" };

is to use split. I find this more readable if there are lots of Strings.

String[] strings =  "abc,def,hij,xyz".split(",");

or the following is good if you are parsing lines of strings from another source.

String[] strings =  ("abc\n" +
                     "def\n" +
                     "hij\n" +
                     "xyz").split("\n");

Violating the Java naming conventions (variable names and method names start with lowercase, class names start with uppercase) is contributing to your confusion.

The variable Random is only "in scope" inside the main method. It's not accessible to any methods called by main. When you return from main, the variable disappears (it's part of the stack frame).

If you want all of the methods of your class to use the same Random instance, declare a member variable:

class MyObj {
  private final Random random = new Random();
  public void compTurn() {
    while (true) {
      int a = random.nextInt(10);
      if (possibles[a] == 1) 
        break;
    }
  }
}

I'm not sure when filtering was added but it's a way to exclude the object blobs if you only want to fetch the history/ref-logs:

git clone --filter=blob:none --no-checkout --single-branch --branch master git://some.repo.git .
git log

It can be that you need to add or update your privacy policy. You can easily create a privacy policy using this template

If you want to install requests directly you can use the "-m" (module) option available to python.

python.exe -m pip install requests

You can do this directly in PowerShell, though you may need to use the full python path (eg. C:\Python27\python.exe) instead of just python.exe.

As mentioned in the comments, if you have added Python to your path you can simply do:

python -m pip install requests

In case your text is compressed inside the blob using DEFLATE algorithm and it's quite large, you can use this function to read it

CREATE OR REPLACE PACKAGE read_gzipped_entity_package AS

FUNCTION read_entity(entity_id IN VARCHAR2)
  RETURN VARCHAR2;

END read_gzipped_entity_package;
/

CREATE OR REPLACE PACKAGE BODY read_gzipped_entity_package IS

FUNCTION read_entity(entity_id IN VARCHAR2) RETURN VARCHAR2
IS
    l_blob              BLOB;
    l_blob_length       NUMBER;
    l_amount            BINARY_INTEGER := 10000; -- must be <= ~32765.
    l_offset            INTEGER := 1;
    l_buffer            RAW(20000);
    l_text_buffer       VARCHAR2(32767);
BEGIN
    -- Get uncompressed BLOB
    SELECT UTL_COMPRESS.LZ_UNCOMPRESS(COMPRESSED_BLOB_COLUMN_NAME)
    INTO   l_blob
    FROM   TABLE_NAME
    WHERE  ID = entity_id;

    -- Figure out how long the BLOB is.
    l_blob_length := DBMS_LOB.GETLENGTH(l_blob);

    -- We'll loop through the BLOB as many times as necessary to
    -- get all its data.
    FOR i IN 1..CEIL(l_blob_length/l_amount) LOOP

        -- Read in the given chunk of the BLOB.
        DBMS_LOB.READ(l_blob
        ,             l_amount
        ,             l_offset
        ,             l_buffer);

        -- The DBMS_LOB.READ procedure dictates that its output be RAW.
        -- This next procedure converts that RAW data to character data.
        l_text_buffer := UTL_RAW.CAST_TO_VARCHAR2(l_buffer);

        -- For the next iteration through the BLOB, bump up your offset
        -- location (i.e., where you start reading from).
        l_offset := l_offset + l_amount;
    END LOOP;
    RETURN l_text_buffer;
EXCEPTION
    WHEN OTHERS THEN
        DBMS_OUTPUT.PUT_LINE('!ERROR: ' || SUBSTR(SQLERRM,1,247));
END;

END read_gzipped_entity_package;
/

Then run select to get text

SELECT read_gzipped_entity_package.read_entity('entity_id') FROM DUAL;

Hope this will help someone.

How about alias gcc99= gcc -std=c99?

Nowadays one can use vw and vh units, which represent 1% of the viewport's width and height respectively.

https://css-tricks.com/fun-viewport-units/

So, for example:

img {
  max-width: 100vw;
  max-height: 100vh;
}

... will make the image as wide as tall as possible, maintaining aspect ratio, but without being wider or higher than 100% of the viewport.

df = pd.DataFrame({'one' : pd.Series([1., 1, 1, 3]), 'two' : pd.Series([1., 2., 1, 3] ), 'three' : pd.Series([1., 2., 1, 2] )})
df['str_list'] = df.apply(lambda row: ' '.join([str(int(val)) for val in row]), axis=1)
df1 = pd.DataFrame(df['str_list'].value_counts().values, index=df['str_list'].value_counts().index, columns=['Count'])

Produces:

>>> df1
       Count
1 1 1      2
3 2 3      1
1 2 2      1

If the index values must be a list, you could take the above code a step further with:

df1.index = df1.index.str.split()

Produces:

           Count
[1, 1, 1]      2
[3, 2, 3]      1
[1, 2, 2]      1

Ok after some hours of research I found svg-android to be quite easy to use, so I'm leaving here step by step instructions:

1. download lib from: https://code.google.com/p/svg-android/downloads/list Latest version at the moment of writing this is: svg-android-1.1.jar

2. Put jar in lib dir.

3. Save your *.svg file in res/drawable dir (In illustrator is as easy as pressing Save as and select svg)

4. Code the following in your activity using the svg library:

   ImageView imageView = (ImageView) findViewById(R.id.imgView);
   SVG svg = SVGParser.getSVGFromResource(getResources(), R.drawable.example);
   //The following is needed because of image accelaration in some devices such as samsung
   imageView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
   imageView.setImageDrawable(svg.createPictureDrawable());
   

You can reduce boilerplate code like this

Very easy I made a simple class to contain past code and reduce boilerplate code, like this:

import android.app.Activity;
import android.view.View;
import android.widget.ImageView;

import com.larvalabs.svgandroid.SVG;
import com.larvalabs.svgandroid.SVGParser;

public class SvgImage {

    private static ImageView imageView;
    private Activity activity;
    private SVG svg;
    private int xmlLayoutId;
    private int drawableId;


    public SvgImage(Activity activity, int layoutId, int drawableId) {
        imageView = (ImageView) activity.findViewById(layoutId);
        svg = SVGParser.getSVGFromResource(activity.getResources(), drawableId);
        //Needed because of image accelaration in some devices such as samsung
        imageView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
        imageView.setImageDrawable(svg.createPictureDrawable());
    }
}

Now I can call it like this in activity:

    SvgImage rainSVG = new SvgImage(MainActivity.this, R.id.rainImageView, R.drawable.rain);
    SvgImage thunderSVG = new SvgImage(MainActivity.this, R.id.thunderImageView, R.drawable.thunder);
    SvgImage oceanSVG = new SvgImage(MainActivity.this, R.id.oceanImageView, R.drawable.ocean);
    SvgImage fireSVG = new SvgImage(MainActivity.this, R.id.fireImageView, R.drawable.fire);
    SvgImage windSVG = new SvgImage(MainActivity.this, R.id.windImageView,R.drawable.wind);
    SvgImage universeSVG = new SvgImage(MainActivity.this, R.id.universeImageView,R.drawable.universe);

I think it's better to divide my answer to 2 parts:

A-Create everything from scratch (using SVG, JavaScript, and HTML5):

1. Create a new HTML5 page
2. Create a new SVG file, each clickable area (province) should be a separate SVG Polygon in your SVG file, (I'm using Adobe Illustrator for creating SVG files but you can find many alternative software products too, for example Inkscape)
3. Add mouseover and click events to your polygons one by one

   <polygon points="200,10 250,190 160,210" style="fill:lime;stroke:purple;stroke-width:1" 
       onmouseover="mouseOverHandler(evt)"
       onclick="clickHandler(evt)" />
   

4. Add a handler for each event in your JavaScript code and add your desired code to the handler

   function mouseOverHandler(evt) {};
   function clickHandler(evt) {};
   

5. Add the SVG file to your HTML page (I prefer inline SVG but you can use linked SVG file too)
6. Upload the files to your server

B-Use a software like FLDraw Interactive Image Creator (only if you have a map image and want to make it interactive):

1. Create an empty project and choose your map image as your base image when creating the new project
2. Add a Polygon element (from the Shape menu) for each province
3. For each polygon double click it to open the Properties window where you can choose an event type for mouse-over and click, also change the shape opacity to 0 to make it invisible
4. Save your project and Publish it to HTML5, FLDraw will create a new folder that contains all of the required files for your project that you can upload to your server.

Option (A) is very good if you are programmer or you have someone to create the required code and SVG file for you, Option (B) is good if you don't want to hire someone or spend your own time for creating everything from scratch

You have some other options too, for example using HTML5 Canvas instead of SVG, but it's not very easy to create a Zoomable map using HTML5 Canvas, maybe there are some other ways too that I'm not aware of.

I had a . in my database name, and the query didn't work because of that (saying Incorrect syntax near '.') Then I realized that I need a bracket for the name:

RESTORE DATABASE [My.DB.Name] WITH RECOVERY

the following can be used:

 install.packages("data.table")
 library(data.table)

Spring 5 has some builtin helper classes for that: org/springframework/jdbc/support/incrementer

simpler with linq:

public void KillProcessesAssociatedToFile(string file)
    {
        GetProcessesAssociatedToFile(file).ForEach(x =>
        {
            x.Kill();
            x.WaitForExit(10000);
        });
    }

    public List<Process> GetProcessesAssociatedToFile(string file)
    {
        return Process.GetProcesses()
            .Where(x => !x.HasExited
                && x.Modules.Cast<ProcessModule>().ToList()
                    .Exists(y => y.FileName.ToLowerInvariant() == file.ToLowerInvariant())
                ).ToList();
    }

Take and store image in desired folder

 //Global Variables
   private static final int CAMERA_IMAGE_REQUEST = 101;
    private String imageName;

Take picture function

 public void captureImage() {

            // Creating folders for Image
            String imageFolderPath = Environment.getExternalStorageDirectory().toString()
                    + "/AutoFare";
            File imagesFolder = new File(imageFolderPath);
            imagesFolder.mkdirs();

            // Generating file name
            imageName = new Date().toString() + ".png";

            // Creating image here
            Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(imageFolderPath, imageName)));
            startActivityForResult(takePictureIntent,
                    CAMERA_IMAGE_REQUEST);

        }

Broadcast new image added otherwise pic will not be visible in image gallery

    public void onActivityResult(int requestCode, int resultCode, Intent data) {
                // TODO Auto-generated method stub
                super.onActivityResult(requestCode, resultCode, data);

                if (resultCode == Activity.RESULT_OK && requestCode == CAMERA_IMAGE_REQUEST) {

                    Toast.makeText(getActivity(), "Success",
                            Toast.LENGTH_SHORT).show();

 //Scan new image added
                    MediaScannerConnection.scanFile(getActivity(), new String[]{new File(Environment.getExternalStorageDirectory()
                            + "/AutoFare/" + imageName).getPath()}, new String[]{"image/png"}, null);


 // Work in few phones
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {

                        getActivity().sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse(Environment.getExternalStorageDirectory()
                                + "/AutoFare/" + imageName)));

                    } else {
                        getActivity().sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse(Environment.getExternalStorageDirectory()
                                + "/AutoFare/" + imageName)));
                    }
                } else {
                    Toast.makeText(getActivity(), "Take Picture Failed or canceled",
                            Toast.LENGTH_SHORT).show();
                }
            }

    <uses-permission android:name="android.permission.CAMERA" />
    <uses-feature android:name="android.hardware.camera" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

I think this is the best way to do it...

You can remove public keyword from your functions, because, you have to define a class in order to declare public, private or protected function

Not always.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52566 has a nice example of two files meant to both be included, but mistakenly thought to be identical because of identical timestamps and content (not identical file name).

Just to document my trouble with this issue even though it just appears to be a specific example of other answers; as a relative newbie I feel like this might help others.

Solution:

I added '/usr/bin' to the beginning of PATH for a single session using PATH='/usr/path/:$PATH' and everything started to work fine.

I used gedit to update the PATH permanently, after ensuring it wouldn't break my regular toolchains.

Explanation:

I have multiple toolchains installed on Ubuntu 14.04LTS and I use just a couple on a regular basis. When I tried to use gcc from the command line I got the issue describe by the OP. '/usr/bin' is in the PATH but it is behind the other toolchain locations. Turns out the cc1 for those other toolchains is incompatible with gcc.

You might try changing this line in your persistence.xml from

<property name="hbm2ddl.auto" value="create"/>

to:

<property name="hibernate.hbm2ddl.auto" value="update"/>

This is supposed to maintain the schema to follow any changes you make to the Model each time you run the app.

Got this from JavaRanch

In pyspark 2.4.4

1) group_by_dataframe.count().filter("`count` >= 10").orderBy('count', ascending=False)

2) from pyspark.sql.functions import desc
   group_by_dataframe.count().filter("`count` >= 10").orderBy('count').sort(desc('count'))

No need to import in 1) and 1) is short & easy to read,
So I prefer 1) over 2)

In my case, it was related to the node version.

My project was using 12.18.3 but I was on 14.5.0

So npm rebuild node-sass didn't solve the issue on the wrong node version(14.5.0).

I switched to the correct version(12.18.3) so it worked.

These types of arrays are known as jagged arrays in Java:

int[][] multD = new int[3][];
multD[0] = new int[3];
multD[1] = new int[2];
multD[2] = new int[5];

In this scenario each row of the array holds the different number of columns. In the above example, the first row will hold three columns, the second row will hold two columns, and the third row holds five columns. You can initialize this array at compile time like below:

 int[][] multD = {{2, 4, 1}, {6, 8}, {7, 3, 6, 5, 1}};

You can easily iterate all elements in your array:

for (int i = 0; i<multD.length; i++) {
    for (int j = 0; j<multD[i].length; j++) {
        System.out.print(multD[i][j] + "\t");
    }
    System.out.println();
}

This is because strings are immutable in Python.

Which means that X.replace("hello","goodbye") returns a copy of X with replacements made. Because of that you need replace this line:

X.replace("hello", "goodbye")

with this line:

X = X.replace("hello", "goodbye")

More broadly, this is true for all Python string methods that change a string's content "in-place", e.g. replace,strip,translate,lower/upper,join,...

You must assign their output to something if you want to use it and not throw it away, e.g.

X  = X.strip(' \t')
X2 = X.translate(...)
Y  = X.lower()
Z  = X.upper()
A  = X.join(':')
B  = X.capitalize()
C  = X.casefold()

and so on.

use this following command:

git push -f origin master

OIDs basically give you a built-in id for every row, contained in a system column (as opposed to a user-space column). That's handy for tables where you don't have a primary key, have duplicate rows, etc. For example, if you have a table with two identical rows, and you want to delete the oldest of the two, you could do that using the oid column.

OIDs are implemented using 4-byte unsigned integers. They are not unique–OID counter will wrap around at 2³²-1. OID are also used to identify data types (see /usr/include/postgresql/server/catalog/pg_type_d.h).

In my experience, the feature is generally unused in most postgres-backed applications (probably in part because they're non-standard), and their use is essentially deprecated:

In PostgreSQL 8.1 default_with_oids is off by default; in prior versions of PostgreSQL, it was on by default.

The use of OIDs in user tables is considered deprecated, so most installations should leave this variable disabled. Applications that require OIDs for a particular table should specify WITH OIDS when creating the table. This variable can be enabled for compatibility with old applications that do not follow this behavior.

For me, the issue's root cause on my Mac device was a version of the flock binary it was not expecting. Removing it from the path did the trick; probably a BSD vs GNU syntax issue.

if ([strpass isEqual:[NSNull null]] || strpass==nil || [strpass isEqualToString:@"<null>"] || [strpass isEqualToString:@"(null)"] || strpass.length==0 || [strpass isEqualToString:@""])
{
    //string is blank  
}

Here's my hero code. I've faced this problem. And use this code to fix this.

 USE master;

    SELECT 
        name, log_reuse_wait, log_reuse_wait_desc, is_cdc_enabled 
    FROM 
        sys.databases 
    WHERE 
        name = 'XX_System';

    SELECT DATABASEPROPERTYEX('XX_System', 'IsPublished');


    USE XX_System;
    EXEC sp_repldone null, null, 0,0,1;
    EXEC sp_removedbreplication XX_System;


    DBCC OPENTRAN;
    DBCC SQLPERF(LOGSPACE);
    EXEC sp_replcounters;



    DBCC SQLPERF(LOGSPACE);

byte[] base64EncodedStringBytes = Encoding.ASCII.GetBytes(Convert.ToBase64String(binaryData))

RPMs are usually built from source, not the binaries.

You need to write the spec file that covers how to configure and compile your application; also, which files to include in your RPM.

A quick glance at the manual shows that most of what you need is covered in Chapter 8 -- also, as most RPM-based distributions have sources available, there's literally a zillion of examples of different approaches you could look at.

Combining Günter Zöchbauer's answer with good-old vanilla-JS, here is a directive with two lines of logic that supports (123) 456-7890 format.

Reactive Forms: Plunk

import { Directive, Output, EventEmitter } from "@angular/core";
import { NgControl } from "@angular/forms";

@Directive({
  selector: '[formControlName][phone]',
  host: {
    '(ngModelChange)': 'onInputChange($event)'
  }
})
export class PhoneMaskDirective {

  @Output() rawChange:EventEmitter<string> = new EventEmitter<string>();

  constructor(public model: NgControl) {}

  onInputChange(value) {
        var x = value.replace(/\D/g, '').match(/(\d{0,3})(\d{0,3})(\d{0,4})/);
        var y = !x[2] ? x[1] : '(' + x[1] + ') ' + x[2] + (x[3] ? '-' + x[3] : '');

        this.model.valueAccessor.writeValue(y);
        this.rawChange.emit(rawValue); 
  }
}

Template-driven Forms: Plunk

import { Directive } from "@angular/core";
import { NgControl } from "@angular/forms";

@Directive({
  selector: '[ngModel][phone]',
  host: {
    '(ngModelChange)': 'onInputChange($event)'
  }
})
export class PhoneMaskDirective {

  constructor(public model: NgControl) {}

  onInputChange(value) {
        var x = value.replace(/\D/g, '').match(/(\d{0,3})(\d{0,3})(\d{0,4})/);
        value = !x[2] ? x[1] : '(' + x[1] + ') ' + x[2] + (x[3] ? '-' + x[3] : '');

        this.model.valueAccessor.writeValue(value);       
  }
}

First of all, there are still browsers out there that don't support those pseudo-elements (ie. :first-child, :last-child), so you have to 'deal' with this issue.

There is a good example how to make that work without using pseudo-elements:

http://www.darowski.com/tracesofinspiration/2010/01/11/this-newbies-first-impressions-of-haml-and-sass/

       -- see the divider pipe example.

I hope that was useful.

On my system (Windows 8.1), Sublime 2 shows default font "Consolas". You can find yours by following this procedure:

1. go to View menu and select Show Console
2. Then enter this command: view.settings().get('font_face')

You will find your default font.

cp -r /home/server/folder/test /home/server/

This would work fine.

Push-Location $PSScriptRoot

Write-Host CurrentDirectory $CurDir

ssize_t is not included in the standard and isn't portable. size_t should be used when handling the size of objects (there's ptrdiff_t too, for pointer differences).

I was able to import the module within the function (only) that would require the objects from this module:

def my_func():
    import Foo
    foo_instance = Foo()

I found that I had bound jFormattedCheckBox1.foreground to jCheckBox1[${selected}].... this was the problem. Thank you for your help.

It seems that a color should not be able to be bound to a boolean. I guess bindings are an advanced feature?

I found the problem by deleting all of the controls, then running, then undoing and then deleting one at a time. When I found the offending control, I examined the properties.

If you only want to remove quotes from the beginning or the end, use the following regular expression:

'"Hello"'.replace(/(^"|"$)/g, '');

I've built a fairly simple, reusable and functional Angular2 autocomplete component based on some of the ideas in this answer/other tutorials around on this subject and others. It's by no means comprehensive but may be helpful if you decide to build your own.

The component:

import { Component, Input, Output, OnInit, ContentChild, EventEmitter, HostListener } from '@angular/core';
import { Observable } from "rxjs/Observable";
import { AutoCompleteRefDirective } from "./autocomplete.directive";

@Component({
    selector: 'autocomplete',
    template: `
<ng-content></ng-content>
<div class="autocomplete-wrapper" (click)="clickedInside($event)">
    <div class="list-group autocomplete" *ngIf="results">
        <a [routerLink]="" class="list-group-item" (click)="selectResult(result)" *ngFor="let result of results; let i = index" [innerHTML]="dataMapping(result) | highlight: query" [ngClass]="{'active': i == selectedIndex}"></a>
    </div>
</div>
    `,
    styleUrls: ['./autocomplete.component.css']
})
export class AutoCompleteComponent implements OnInit {

    @ContentChild(AutoCompleteRefDirective)
    public input: AutoCompleteRefDirective;

    @Input() data: (searchTerm: string) => Observable<any[]>;
    @Input() dataMapping: (obj: any) => string;
    @Output() onChange = new EventEmitter<any>();

    @HostListener('document:click', ['$event'])
    clickedOutside($event: any): void {
        this.clearResults();
    }

    public results: any[];
    public query: string;
    public selectedIndex: number = 0;
    private searchCounter: number = 0;

    ngOnInit(): void {
        this.input.change
            .subscribe((query: string) => {
                this.query = query;
                this.onChange.emit();
                this.searchCounter++;
                let counter = this.searchCounter;

                if (query) {
                    this.data(query)
                        .subscribe(data => {
                            if (counter == this.searchCounter) {
                                this.results = data;
                                this.input.hasResults = data.length > 0;
                                this.selectedIndex = 0;
                            }
                        });
                }
                else this.clearResults();
            });

        this.input.cancel
            .subscribe(() => {
                this.clearResults();
            });

        this.input.select
            .subscribe(() => {
                if (this.results && this.results.length > 0)
                {
                    this.selectResult(this.results[this.selectedIndex]);
                }
            });

        this.input.up
            .subscribe(() => {
                if (this.results && this.selectedIndex > 0) this.selectedIndex--;
            });

        this.input.down
            .subscribe(() => {
                if (this.results && this.selectedIndex + 1 < this.results.length) this.selectedIndex++;
            });
    }

    selectResult(result: any): void {
        this.onChange.emit(result);
        this.clearResults();
    }

    clickedInside($event: any): void {
        $event.preventDefault();
        $event.stopPropagation();
    }

    private clearResults(): void {
        this.results = [];
        this.selectedIndex = 0;
        this.searchCounter = 0;
        this.input.hasResults = false;
    }
}

The component CSS:

.autocomplete-wrapper {
    position: relative;
}

.autocomplete {
    position: absolute;
    z-index: 100;
    width: 100%;
}

The directive:

import { Directive, Input, Output, HostListener, EventEmitter } from '@angular/core';

@Directive({
    selector: '[autocompleteRef]'
})
export class AutoCompleteRefDirective {
    @Input() hasResults: boolean = false;
    @Output() change = new EventEmitter<string>();
    @Output() cancel = new EventEmitter();
    @Output() select = new EventEmitter();
    @Output() up = new EventEmitter();
    @Output() down = new EventEmitter();

    @HostListener('input', ['$event'])
    oninput(event: any) {
        this.change.emit(event.target.value);
    }

    @HostListener('keydown', ['$event'])
    onkeydown(event: any)
    {
        switch (event.keyCode) {
            case 27:
                this.cancel.emit();
                return false;
            case 13:
                var hasResults = this.hasResults;
                this.select.emit();
                return !hasResults;
            case 38:
                this.up.emit();
                return false;
            case 40:
                this.down.emit();
                return false;
            default:
        }
    }
}

The highlight pipe:

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

@Pipe({
    name: 'highlight'
})

export class HighlightPipe implements PipeTransform {
    transform(value: string, args: any): any {
        var re = new RegExp(args, 'gi');

        return value.replace(re, function (match) {
            return "<strong>" + match + "</strong>";
        })

    }
}

The implementation:

import { Component } from '@angular/core';
import { Observable } from "rxjs/Observable";
import { Subscriber } from "rxjs/Subscriber";

@Component({
    selector: 'home',
    template: `
<autocomplete [data]="getData" [dataMapping]="dataMapping" (onChange)="change($event)">
    <input type="text" class="form-control" name="AutoComplete" placeholder="Search..." autocomplete="off" autocompleteRef />
</autocomplete>
    `
})
export class HomeComponent {

    getData = (query: string) => this.search(query);

    // The dataMapping property controls the mapping of an object returned via getData.
    // to a string that can be displayed to the use as an option to select.
    dataMapping = (obj: any) => obj;

    // This function is called any time a change is made in the autocomplete.
    // When the text is changed manually, no object is passed.
    // When a selection is made the object is passed.
    change(obj: any): void {
        if (obj) {
            // You can do pretty much anything here as the entire object is passed if it's been selected.
            // Navigate to another page, update a model etc.
            alert(obj);
        }
    }

    private searchData = ['one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine', 'ten'];

    // This function mimics an Observable http service call.
    // In reality it's probably calling your API, but today it's looking at mock static data.
    private search(query: string): Observable<any>
    {
        return new Observable<any>((subscriber: Subscriber<any>) => subscriber
            .next())
            .map(o => this.searchData.filter(d => d.indexOf(query) > -1));
    }
}

Consider using HashSet<T> Class for the sake of lookup performance:

This method is an O(1) operation.

— HashSet<T>.Contains Method (T), MSDN.

For example:

class PrinterInstaller
{
    private static readonly HashSet<string> PrinterNames = new HashSet<string>
        {
            "jupiter", "neptune", "pangea", "mercury", "sonic"
        };

    public void Setup(string printerName)
    {
        if (!PrinterNames.Contains(printerName))
        {
            throw new ArgumentException("Unknown printer name", "printerName");
        }
        // ...
    }
}

Your question "what are they" is already answered above.

As far as debugging (your second question) though, and in developing libraries where you want to check for special input values, you may find the following functions useful in Windows C++:

_isnan(), _isfinite(), and _fpclass()

On Linux/Unix you should find isnan(), isfinite(), isnormal(), isinf(), fpclassify() useful (and you may need to link with libm by using the compiler flag -lm).

Just use if and env.BRANCH_NAME, example:

    if (env.BRANCH_NAME == "deployment") {                                          
        ... do some build ...
    } else {                                   
        ... do something else ...
    }                                                                       

The underlying problem here is the 1st level cache of JPA. From the JPA spec Version 2.2 section 3.1. emphasise is mine:

An EntityManager instance is associated with a persistence context. A persistence context is a set of entity instances in which for any persistent entity identity there is a unique entity instance.

This is important because JPA tracks changes to that entity in order to flush them to the database. As a side effect it also means within a single persistence context an entity gets only loaded once. This why reloading the changed entity doesn't have any effect.

You have a couple of options how to handle this:

1. Evict the entity from the EntityManager. This may be done by calling EntityManager.detach, annotating the updating method with @Modifying(clearAutomatically = true) which evicts all entities. Make sure changes to these entities get flushed first or you might end up loosing changes.

2. Use EntityManager.refresh().

3. Use a different persistence context to load the entity. The easiest way to do this is to do it in a separate transaction. With Spring this can be done by having separate methods annotated with @Transactional on beans called from a bean not annotated with @Transactional. Another way is to use a TransactionTemplate which works especially nicely in tests where it makes transaction boundaries very visible.

Agile is not a methodology, embracing the agile manifesto means adopting a particular philosophy about software development. Within that philosophical perspective, there are many processes and practices. Scrum is a set of practices that follow agile principles. Many people grab onto the practices and processes without embracing (or even understanding) the underlying philosophy and they often end up with gorillarinas.

Parse that string into a Date object:

var myDate = new Date('10/11/1955 10:40:50 AM');

Then use the usual methods to get the date's day of month (getDate) / month (getMonth) / year (getFullYear).

var noTime = new Date(myDate.getFullYear(), myDate.getMonth(), myDate.getDate());

public class LoginTest extends BaseTest {
    @Test
    public void exampleTest( ){ 
        // Test
    }
}

Inherits from a base test class (this example is testng rather than jUnit, but the ActiveProfiles is the same):

@ContextConfiguration(locations = { "classpath:spring-test-config.xml" })
@ActiveProfiles(resolver = MyActiveProfileResolver.class)
public class BaseTest extends AbstractTestNGSpringContextTests { }

MyActiveProfileResolver can contain any logic required to determine which profile to use:

public class MyActiveProfileResolver implements ActiveProfilesResolver {
    @Override
    public String[] resolve(Class<?> aClass) {
        // This can contain any custom logic to determine which profiles to use
        return new String[] { "exampleProfile" };
    }
}

This sets the profile which is then used to resolve dependencies required by the test.

In view there is not any direct or physical relation with the database. And Modification through a view (e.g. insert, update, delete) is not permitted.Its just a logical set of tables

Are you running a 64 bit system with the database running 32 bit but the console running 64 bit? There are no MS Access drivers that run 64 bit and would report an error identical to the one your reported.

<div class="small hidden-xs">
    Some Content Here
</div>

This also works for elements not necessarily used in a grid /small column. When it is rendered on larger screens the font-size will be smaller than your default text font-size.

This answer satisfies the question in the OP title (which is how I found this Q/A).

Create initMap method between "" tag or load javascript file before call google api.

The solution found here helped us to update master to a previous commit that had already been pushed:

git checkout master
git reset --hard e3f1e37
git push --force origin e3f1e37:master

The key difference from the accepted answer is the commit hash "e3f1e37:" before master in the push command.

I wrote two functions to flatten and unflatten a JSON object.

Flatten a JSON object:

var flatten = (function (isArray, wrapped) {
    return function (table) {
        return reduce("", {}, table);
    };

    function reduce(path, accumulator, table) {
        if (isArray(table)) {
            var length = table.length;

            if (length) {
                var index = 0;

                while (index < length) {
                    var property = path + "[" + index + "]", item = table[index++];
                    if (wrapped(item) !== item) accumulator[property] = item;
                    else reduce(property, accumulator, item);
                }
            } else accumulator[path] = table;
        } else {
            var empty = true;

            if (path) {
                for (var property in table) {
                    var item = table[property], property = path + "." + property, empty = false;
                    if (wrapped(item) !== item) accumulator[property] = item;
                    else reduce(property, accumulator, item);
                }
            } else {
                for (var property in table) {
                    var item = table[property], empty = false;
                    if (wrapped(item) !== item) accumulator[property] = item;
                    else reduce(property, accumulator, item);
                }
            }

            if (empty) accumulator[path] = table;
        }

        return accumulator;
    }
}(Array.isArray, Object));

Performance:

1. It's faster than the current solution in Opera. The current solution is 26% slower in Opera.
2. It's faster than the current solution in Firefox. The current solution is 9% slower in Firefox.
3. It's faster than the current solution in Chrome. The current solution is 29% slower in Chrome.

Unflatten a JSON object:

function unflatten(table) {
    var result = {};

    for (var path in table) {

                    bracket = path.indexOf("[", start),
                    dot = path.indexOf(".", start);

                if (bracket < 0 && dot < 0) var end = index = length;
                else if (bracket < 0) var end = index = dot;
                else if (dot < 0) var end = index = bracket;
                else var end = index = bracket < dot ? bracket : dot;

Performance:

1. It's faster than the current solution in Opera. The current solution is 5% slower in Opera.
2. It's slower than the current solution in Firefox. My solution is 26% slower in Firefox.
3. It's slower than the current solution in Chrome. My solution is 6% slower in Chrome.

Flatten and unflatten a JSON object:

Overall my solution performs either equally well or even better than the current solution.

Performance:

1. It's faster than the current solution in Opera. The current solution is 21% slower in Opera.
2. It's as fast as the current solution in Firefox.
3. It's faster than the current solution in Firefox. The current solution is 20% slower in Chrome.

Output format:

A flattened object uses the dot notation for object properties and the bracket notation for array indices:

1. {foo:{bar:false}} => {"foo.bar":false}
2. {a:[{b:["c","d"]}]} => {"a[0].b[0]":"c","a[0].b[1]":"d"}
3. [1,[2,[3,4],5],6] => {"[0]":1,"[1][0]":2,"[1][1][0]":3,"[1][1][1]":4,"[1][2]":5,"[2]":6}

In my opinion this format is better than only using the dot notation:

1. {foo:{bar:false}} => {"foo.bar":false}
2. {a:[{b:["c","d"]}]} => {"a.0.b.0":"c","a.0.b.1":"d"}
3. [1,[2,[3,4],5],6] => {"0":1,"1.0":2,"1.1.0":3,"1.1.1":4,"1.2":5,"2":6}

Advantages:

1. Flattening an object is faster than the current solution.
2. Flattening and unflattening an object is as fast as or faster than the current solution.
3. Flattened objects use both the dot notation and the bracket notation for readability.

Disadvantages:

1. Unflattening an object is slower than the current solution in most (but not all) cases.

The current JSFiddle demo gave the following values as output:

Nested : 132175 : 63
Flattened : 132175 : 564
Nested : 132175 : 54
Flattened : 132175 : 508

My updated JSFiddle demo gave the following values as output:

Nested : 132175 : 59
Flattened : 132175 : 514
Nested : 132175 : 60
Flattened : 132175 : 451

I'm not really sure what that means, so I'll stick with the jsPerf results. After all jsPerf is a performance benchmarking utility. JSFiddle is not.

I think I know where your question is headed. And since this question is the one that pop ups in google's search main results, I can give a plain answer on what the @Valid annotation does.

I'll present 3 scenarios on how I've used @Valid

Model:

public class Employee{
private String name;
@NotNull(message="cannot be null")
@Size(min=1, message="cannot be blank")
private String lastName;
 //Getters and Setters for both fields.
 //...
}

JSP:

...
<form:form action="processForm" modelAttribute="employee">
 <form:input type="text" path="name"/>
 <br>
 <form:input type="text" path="lastName"/>
<form:errors path="lastName"/>
<input type="submit" value="Submit"/>
</form:form>
...

Controller for scenario 1:

     @RequestMapping("processForm")
        public String processFormData(@Valid @ModelAttribute("employee") Employee employee){
        return "employee-confirmation-page";
    }

In this scenario, after submitting your form with an empty lastName field, you'll get an error page since you're applying validation rules but you're not handling it whatsoever.

Example of said error: Exception page

Controller for scenario 2:

 @RequestMapping("processForm")
    public String processFormData(@Valid @ModelAttribute("employee") Employee employee,
BindingResult bindingResult){
                return bindingResult.hasErrors() ? "employee-form" : "employee-confirmation-page";
            }

In this scenario, you're passing all the results from that validation to the bindingResult, so it's up to you to decide what to do with the validation results of that form.

Controller for scenario 3:

@RequestMapping("processForm")
    public String processFormData(@Valid @ModelAttribute("employee") Employee employee){
                return "employee-confirmation-page";
            }
@ExceptionHandler(MethodArgumentNotValidException.class)
@ResponseStatus(HttpStatus.BAD_REQUEST)
public Map<String, String> invalidFormProcessor(MethodArgumentNotValidException ex){
  //Your mapping of the errors...etc
}

In this scenario you're still not handling the errors like in the first scenario, but you pass that to another method that will take care of the exception that @Valid triggers when processing the form model. Check this see what to do with the mapping and all that.

To sum up: @Valid on its own with do nothing more that trigger the validation of validation JSR 303 annotated fields (@NotNull, @Email, @Size, etc...), you still need to specify a strategy of what to do with the results of said validation.

Hope I was able to clear something for people that might stumble with this.

Other answer were not working with a generic interface.

This one does, just replace typeof(ISomeInterface) by typeof (T).

List<string> types = AppDomain.CurrentDomain.GetAssemblies().SelectMany(x => x.GetTypes())
            .Where(x => typeof(ISomeInterface).IsAssignableFrom(x) && !x.IsInterface && !x.IsAbstract)
            .Select(x => x.Name).ToList();

So with

AppDomain.CurrentDomain.GetAssemblies().SelectMany(x => x.GetTypes())

we get all the assemblies

!x.IsInterface && !x.IsAbstract

is used to exclude the interface and abstract ones and

.Select(x => x.Name).ToList();

to have them in a list.

Here is a very simple and common example.

The RSA encryption algorithm which is commonly used in secure commerce web sites, is based on the fact that it is easy to take two (very large) prime numbers and multiply them, while it is extremely hard to do the opposite - meaning: take a very large number, given which it has only two prime factors, and find them.

From the documentation:

With one argument, return the natural logarithm of x (to base e).

With two arguments, return the logarithm of x to the given base, calculated as log(x)/log(base).

But the log₁₀ is made available as math.log10(), which does not resort to log division if possible.

It is important to understand that accessors restrict access to variable, but not their content. In ruby, like in some other OO languages, every variable is a pointer to an instance. So if you have an attribute to an Hash, for example, and you set it to be "read only" you always could change its content, but not the content of pointer. Look at this:

irb(main):024:0> class A
irb(main):025:1> attr_reader :a
irb(main):026:1> def initialize
irb(main):027:2> @a = {a:1, b:2}
irb(main):028:2> end
irb(main):029:1> end
=> :initialize
irb(main):030:0> a = A.new
=> #<A:0x007ffc5a10fe88 @a={:a=>1, :b=>2}>
irb(main):031:0> a.a
=> {:a=>1, :b=>2}
irb(main):032:0> a.a.delete(:b)
=> 2
irb(main):033:0> a.a
=> {:a=>1}
irb(main):034:0> a.a = {}
NoMethodError: undefined method `a=' for #<A:0x007ffc5a10fe88 @a={:a=>1}>
        from (irb):34
        from /usr/local/bin/irb:11:in `<main>'

As you can see is possible delete a key/value pair from the Hash @a, as add new keys, change values, eccetera. But you can't point to a new object because is a read only instance variable.

Check below example

<script src='https://www.google.com/recaptcha/api.js'></script>
<script>

function get_action(form) 
{
    var v = grecaptcha.getResponse();
    if(v.length == 0)
    {
        document.getElementById('captcha').innerHTML="You can't leave Captcha Code empty";
        return false;
    }
    else
    {
         document.getElementById('captcha').innerHTML="Captcha completed";
        return true; 
    }
}

</script>
<form autocomplete="off" method="post" action=submit.php">

    <input type="text" name="name">
    <input type="text" name="email">
    <div class="g-recaptcha" id="rcaptcha"  data-sitekey="site key"></div>
    <span id="captcha" style="color:red" /></span> <!-- this will show captcha errors -->
    <input type="submit" id="sbtBrn" value="Submit" name="sbt" class="btn btn-info contactBtn" />
</form>

This is probably the shortest and easiest to reason about:

$states = array('az' => 'Arizona', 'al' => 'Alabama');

array_map(function ($short, $long) {
    return array(
        'short' => $short,
        'long'  => $long
    );
}, array_keys($states), $states);

// produces:
array(
     array('short' => 'az', 'long' => 'Arizona'), 
     array('short' => 'al', 'long' => 'Alabama')
)

For the answer above, the default serial port is

        serialParams.BaudRate = 9600;
        serialParams.ByteSize = 8;
        serialParams.StopBits = TWOSTOPBITS;
        serialParams.Parity = NOPARITY;

This version need not math library and checked the return value of clock_gettime().

#include <time.h>
#include <stdlib.h>
#include <stdint.h>

/**
 * @return milliseconds
 */
uint64_t get_now_time() {
  struct timespec spec;
  if (clock_gettime(1, &spec) == -1) { /* 1 is CLOCK_MONOTONIC */
    abort();
  }

  return spec.tv_sec * 1000 + spec.tv_nsec / 1e6;
}

I had similar situation:

$foo = array();
$foo[] = 'test'; // error    
$foo[] = "test"; // working fine

Either the parameter supplied for ZIP_CODE is larger (in length) than ZIP_CODEs column width or the parameter supplied for CITY is larger (in length) than CITYs column width.

It would be interesting to know the values supplied for the two ? placeholders.

Once you pass the assembly instance back to the caller domain, the caller domain will try to load it! This is why you get the exception. This happens in your last line of code:

domain.Load(AssemblyName.GetAssemblyName(path));

Thus, whatever you want to do with the assembly, should be done in a proxy class - a class which inherit MarshalByRefObject.

Take in count that the caller domain and the new created domain should both have access to the proxy class assembly. If your issue is not too complicated, consider leaving the ApplicationBase folder unchanged, so it will be same as the caller domain folder (the new domain will only load Assemblies it needs).

In simple code:

public void DoStuffInOtherDomain()
{
    const string assemblyPath = @"[AsmPath]";
    var newDomain = AppDomain.CreateDomain("newDomain");
    var asmLoaderProxy = (ProxyDomain)newDomain.CreateInstanceAndUnwrap(Assembly.GetExecutingAssembly().FullName, typeof(ProxyDomain).FullName);

    asmLoaderProxy.GetAssembly(assemblyPath);
}

class ProxyDomain : MarshalByRefObject
{
    public void GetAssembly(string AssemblyPath)
    {
        try
        {
            Assembly.LoadFrom(AssemblyPath);
            //If you want to do anything further to that assembly, you need to do it here.
        }
        catch (Exception ex)
        {
            throw new InvalidOperationException(ex.Message, ex);
        }
    }
}

If you do need to load the assemblies from a folder which is different than you current app domain folder, create the new app domain with specific dlls search path folder.

For example, the app domain creation line from the above code should be replaced with:

var dllsSearchPath = @"[dlls search path for new app domain]";
AppDomain newDomain = AppDomain.CreateDomain("newDomain", new Evidence(), dllsSearchPath, "", true);

This way, all the dlls will automaically be resolved from dllsSearchPath.

The best is QSpinBox.

And for a double value use QDoubleSpinBox.

QSpinBox myInt;
myInt.setMinimum(-5);
myInt.setMaximum(5);
myInt.setSingleStep(1);// Will increment the current value with 1 (if you use up arrow key) (if you use down arrow key => -1)
myInt.setValue(2);// Default/begining value
myInt.value();// Get the current value
//connect(&myInt, SIGNAL(valueChanged(int)), this, SLOT(myValueChanged(int)));

With attribute selector we target input type text in CSS

input[type=text] {
background:gold;
font-size:15px;
 }

you can use the pow method from the Math class. The following code will output 2 raised to 3 (8)

System.out.println(Math.pow(2, 3));

Ruby provides another way to handle STDIN: The -n flag. It treats your entire program as being inside a loop over STDIN, (including files passed as command line args). See e.g. the following 1-line script:

#!/usr/bin/env ruby -n

#example.rb

puts "hello: #{$_}" #prepend 'hello:' to each line from STDIN

#these will all work:
# ./example.rb < input.txt
# cat input.txt | ./example.rb
# ./example.rb input.txt

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

Use TIMESTAMP instead:

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

, possibly casting it to a DATE then:

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

Match match = Regex.Match(host, "([^.]+\\.[^.]{1,3}(\\.[^.]{1,3})?)$");
string domain = match.Groups[1].Success ? match.Groups[1].Value : null;

host.com => return host.com
s.host.com => return host.com

host.co.uk => return host.co.uk
www.host.co.uk => return host.co.uk
s1.www.host.co.uk => return host.co.uk

In order to show please select a value in drop down and hide it after some value is selected . please use the below code.

it will also support required validation.

<select class="form-control" required>_x000D_
<option disabled selected value style="display:none;">--Please select a value</option>_x000D_
              <option >Data 1</option>_x000D_
              <option >Data 2</option>_x000D_
              <option >Data 3</option>_x000D_
</select>

In PHP 5.3 or greater, you can get it like this:

$ip = getenv('HTTP_CLIENT_IP')?:
getenv('HTTP_X_FORWARDED_FOR')?:
getenv('HTTP_X_FORWARDED')?:
getenv('HTTP_FORWARDED_FOR')?:
getenv('HTTP_FORWARDED')?:
getenv('REMOTE_ADDR');

I think it depends on what problems you are facing.

1. shortest path on simple graph -> bfs
2. all possible results -> dfs
3. search on graph(treat tree, martix as a graph too) -> dfs ....

Use Conda instead of pip. It works perfectly

conda install PyAudio

As others have noted, it is usually preferable to specify a minimum logging level to log that level and any others more severe than it. It seems like you are just thinking about the logging levels backwards.

However, if you want more fine-grained control over logging individual levels, you can tell log4net to log only one or more specific levels using the following syntax:

<filter type="log4net.Filter.LevelMatchFilter">
  <levelToMatch value="WARN"/>
</filter>

Or to exclude a specific logging level by adding a "deny" node to the filter.

You can stack multiple filters together to specify multiple levels. For instance, if you wanted only WARN and FATAL levels. If the levels you wanted were consecutive, then the LevelRangeFilter is more appropriate.

Reference Doc: log4net.Filter.LevelMatchFilter

If the other answers haven't given you enough information, hopefully this will help you get what you want out of log4net.

Necromancing.
In .NET Core/NetStandard2, you can use Nito.AsyncEx.AsyncContext.Run instead of System.Windows.Threading.Dispatcher.InvokeAsync:

class AsyncPropertyTest
{

    private static async System.Threading.Tasks.Task<int> GetInt(string text)
    {
        await System.Threading.Tasks.Task.Delay(2000);
        System.Threading.Thread.Sleep(2000);
        return int.Parse(text);
    }


    public static int MyProperty
    {
        get
        {
            int x = 0;

            // https://stackoverflow.com/questions/6602244/how-to-call-an-async-method-from-a-getter-or-setter
            // https://stackoverflow.com/questions/41748335/net-dispatcher-for-net-core
            // https://github.com/StephenCleary/AsyncEx
            Nito.AsyncEx.AsyncContext.Run(async delegate ()
            {
                x = await GetInt("123");
            });

            return x;
        }
    }


    public static void Test()
    {
        System.Console.WriteLine(System.DateTime.Now.ToString("dd.MM.yyyy HH:mm:ss.fff"));
        System.Console.WriteLine(MyProperty);
        System.Console.WriteLine(System.DateTime.Now.ToString("dd.MM.yyyy HH:mm:ss.fff"));
    }


}

If you simply chose System.Threading.Tasks.Task.Run or System.Threading.Tasks.Task<int>.Run, then it wouldn't work.

You can also use TempVars - note '!' syntax is essential

Today, I have used this feature, so here's my very fresh real-life example. (I have changed class and method names to generic ones so they won't distract from the actual point.)

I have a method that's meant to accept a Set of A objects that I originally wrote with this signature:

void myMethod(Set<A> set)

But it want to actually call it with Sets of subclasses of A. But this is not allowed! (The reason for that is, myMethod could add objects to set that are of type A, but not of the subtype that set's objects are declared to be at the caller's site. So this could break the type system if it were possible.)

Now here come generics to the rescue, because it works as intended if I use this method signature instead:

<T extends A> void myMethod(Set<T> set)

or shorter, if you don't need to use the actual type in the method body:

void myMethod(Set<? extends A> set)

This way, set's type becomes a collection of objects of the actual subtype of A, so it becomes possible to use this with subclasses without endangering the type system.

  public function getYear($pdate) {
    $date = DateTime::createFromFormat("Y-m-d", $pdate);
    return $date->format("Y");
}

public function getMonth($pdate) {
    $date = DateTime::createFromFormat("Y-m-d", $pdate);
    return $date->format("m");
}

public function getDay($pdate) {
    $date = DateTime::createFromFormat("Y-m-d", $pdate);
    return $date->format("d");
}

From the code that you have provided, not knowing the language that you are programming in. The variable capital is null. When you are trying to read the property length, the system cant as it is trying to deference a null variable. You need to define capital.

All of these are good answers, but I would like to suggest one more that I feel is a better code standard. You may choose to use a flag in the loop condition that indicates whether or not to continue looping and avoid using break all together.

$arr = array('one', 'two', 'three', 'four', 'stop', 'five');
$length = count($arr);
$found = false;
for ($i = 0; $i < $length && !$found; $i++) {
    $val = $arr[$i];
    if ($val == 'stop') {
        $found = true; // this will cause the code to 
                       // stop looping the next time 
                       // the condition is checked
    }
    echo "$val<br />\n";
}

I consider this to be better code practice because it does not rely on the scope that break is used. Rather, you define a variable that indicates whether or not to break a specific loop. This is useful when you have many loops that may or may not be nested or sequential.

mysqli_select_db() should have 2 parameters, the connection link and the database name -

mysqli_select_db($con, 'phpcadet') or die(mysqli_error($con));

Using mysqli_error in the die statement will tell you exactly what is wrong as opposed to a generic error message.

Here is a dplyr/tidyverse solution using the na_if() function:

dat %>% mutate_if(is.numeric, list(~na_if(., Inf)))

Note that this only replaces positive infinity with NA. Need to repeat if negative infinity values also need to be replaced.

dat %>% mutate_if(is.numeric, list(~na_if(., Inf))) %>% 
  mutate_if(is.numeric, list(~na_if(., -Inf)))

When you want a relative path from your home directory (on any UNIX) you use this strange syntax:

ssh://[user@]host.xz[:port]/~[user]/path/to/repo

For Example, if the repo is in /home/jack/projects/jillweb on the server jill.com and you are logging in as jack with sshd listening on port 4242:

ssh://[email protected]:4242/~/projects/jillweb

And when logging in as jill (presuming you have file permissions):

ssh://[email protected]:4242/~jack/projects/jillweb

You can try this one, it works just fine :

`   ImageIcon icon = new ImageIcon(".//Ressources//User_50.png");
    this.setIconImage(icon.getImage());`

If you're running a jar file with java -jar, the -classpath argument is ignored. You need to set the classpath in the manifest file of your jar, like so:

Class-Path: jar1-name jar2-name directory-name/jar3-name

See the Java tutorials: Adding Classes to the JAR File's Classpath.

Edit: I see you already tried setting the class path in the manifest, but are you sure you used the correct syntax? If you skip the ':' after "Class-Path" like you showed, it would not work.

For the correct solution after many hours:

1. Open the configuration file
2. Change the connection string with the following

<add name="umbracoDbDSN" connectionString="data source=YOUR_SERVER_NAME;database=nrc;Integrated Security=SSPI;persist security info=True;" providerName="System.Data.SqlClient" />

3. Change the YOUR_SERVER_NAME with your current server name and save
4. Open the IIS Manager
5. Find the name of the application pool that the website or web application is using
6. Right-click and choose Advanced settings
7. From Advanced settings under Process Model change the Identity to Custom account and add your Server Admin details, please see the attached images:

Hope this will help.

You have ArrayList all wrong,

• You can't have an integer array and assign a string value.
• You cannot do a add() method in an array

Rather do this:

List<String> alist = new ArrayList<String>();
alist.add("apple");
alist.add("banana");
alist.add("orange");

String value = alist.get(1); //returns the 2nd item from list, in this case "banana"

Indexing is counted from 0 to N-1 where N is size() of list.

From the Java Language Specification, section 15.9.5.1:

An anonymous class cannot have an explicitly declared constructor.

Sorry :(

EDIT: As an alternative, you can create some final local variables, and/or include an instance initializer in the anonymous class. For example:

public class Test {
    public static void main(String[] args) throws Exception {
        final int fakeConstructorArg = 10;

        Object a = new Object() {
            {
                System.out.println("arg = " + fakeConstructorArg);
            }
        };
    }
}

It's grotty, but it might just help you. Alternatively, use a proper nested class :)

If you don't need a signed integer, this is an alternative that uses a slightly different approach, is easy to read and doesn't require an import:

def distance(a, b):
  if a > 0 and b > 0:
    return max(a, b) - min(a, b)
  elif a < 0 and b < 0:
    return abs(a - b)
  elif a == b:
    return 0
  return abs(a - 0) + abs(b - 0)

_{In addition to romkyns's great answer.. here is some relevant documentation/examples.}

DOM Elements have a native .click() method.

The HTMLElement.click() method simulates a mouse click on an element.

When click is used, it also fires the element's click event which will bubble up to elements higher up the document tree (or event chain) and fire their click events too. However, bubbling of a click event will not cause an <a> element to initiate navigation as if a real mouse-click had been received. (mdn reference)

Relevant W3 documentation.

A few examples..

• You can access a specific DOM element from a jQuery object: (example)

    $('a')[0].click();
  

• You can use the .get() method to retrieve a DOM element from a jQuery object: (example)

    $('a').get(0).click();
  

• As expected, you can select the DOM element and call the .click() method. (example)

    document.querySelector('a').click();
  

It's worth pointing out that jQuery is not required to trigger a native .click() event.

Most of the answer is in existing replies, but for me not quite. This is what works for me with java.net.HttpURLConnection (I have tested all the cases with JDK 7 and JDK 8). Note that you do not have to use the Authenticator class.

Case 1 : Proxy without user authentication, access HTTP resources

-Dhttp.proxyHost=myproxy -Dhttp.proxyPort=myport

Case 2 : Proxy with user authentication, access HTTP resources

-Dhttp.proxyHost=myproxy -Dhttp.proxyPort=myport -Dhttps.proxyUser=myuser -Dhttps.proxyPassword=mypass

Case 3 : Proxy without user authentication, access HTTPS resources (SSL)

-Dhttps.proxyHost=myproxy -Dhttps.proxyPort=myport 

Case 4 : Proxy with user authentication, access HTTPS resources (SSL)

-Dhttps.proxyHost=myproxy -Dhttps.proxyPort=myport -Dhttps.proxyUser=myuser -Dhttps.proxyPassword=mypass

Case 5 : Proxy without user authentication, access both HTTP and HTTPS resources (SSL)

-Dhttp.proxyHost=myproxy -Dhttp.proxyPort=myport -Dhttps.proxyHost=myproxy -Dhttps.proxyPort=myport 

Case 6 : Proxy with user authentication, access both HTTP and HTTPS resources (SSL)

-Dhttp.proxyHost=myproxy -Dhttp.proxyPort=myport -Dhttp.proxyUser=myuser -Dhttp.proxyPassword=mypass -Dhttps.proxyHost=myproxy -Dhttps.proxyPort=myport -Dhttps.proxyUser=myuser -Dhttps.proxyPassword=mypass

You can set the properties in the with System.setProperty("key", "value) too.

To access HTTPS resource you may have to trust the resource by downloading the server certificate and saving it in a trust store and then using that trust store. ie

 System.setProperty("javax.net.ssl.trustStore", "c:/temp/cert-factory/my-cacerts");
 System.setProperty("javax.net.ssl.trustStorePassword", "changeit");

From man curl:

-x, --proxy <[protocol://][user:password@]proxyhost[:port]>

     Use the specified HTTP proxy. 
     If the port number is not specified, it is assumed at port 1080.

General way:

export http_proxy=http://your.proxy.server:port/

Then you can connect through proxy from (many) application.

And, as per comment below, for https:

export https_proxy=https://your.proxy.server:port/

Python is a dynamic, strongly typed, object oriented, multipurpose programming language, designed to be quick (to learn, to use, and to understand), and to enforce a clean and uniform syntax.

1. Python is dynamically typed: it means that you don't declare a type (e.g. 'integer') for a variable name, and then assign something of that type (and only that type). Instead, you have variable names, and you bind them to entities whose type stays with the entity itself. a = 5 makes the variable name a to refer to the integer 5. Later, a = "hello" makes the variable name a to refer to a string containing "hello". Static typed languages would have you declare int a and then a = 5, but assigning a = "hello" would have been a compile time error. On one hand, this makes everything more unpredictable (you don't know what a refers to). On the other hand, it makes very easy to achieve some results a static typed languages makes very difficult.
2. Python is strongly typed. It means that if a = "5" (the string whose value is '5') will remain a string, and never coerced to a number if the context requires so. Every type conversion in python must be done explicitly. This is different from, for example, Perl or Javascript, where you have weak typing, and can write things like "hello" + 5 to get "hello5".
3. Python is object oriented, with class-based inheritance. Everything is an object (including classes, functions, modules, etc), in the sense that they can be passed around as arguments, have methods and attributes, and so on.
4. Python is multipurpose: it is not specialised to a specific target of users (like R for statistics, or PHP for web programming). It is extended through modules and libraries, that hook very easily into the C programming language.
5. Python enforces correct indentation of the code by making the indentation part of the syntax. There are no control braces in Python. Blocks of code are identified by the level of indentation. Although a big turn off for many programmers not used to this, it is precious as it gives a very uniform style and results in code that is visually pleasant to read.
6. The code is compiled into byte code and then executed in a virtual machine. This means that precompiled code is portable between platforms.

Python can be used for any programming task, from GUI programming to web programming with everything else in between. It's quite efficient, as much of its activity is done at the C level. Python is just a layer on top of C. There are libraries for everything you can think of: game programming and openGL, GUI interfaces, web frameworks, semantic web, scientific computing...

The closest equivalent to Java's toString is to implement __str__ for your class. Put this in your class definition:

def __str__(self):
     return "foo"

You may also want to implement __repr__ to aid in debugging.

See here for more information:

Actually, from my calculations, the "perfect" load factor is closer to log 2 (~ 0.7). Although any load factor less than this will yield better performance. I think that .75 was probably pulled out of a hat.

Proof:

Chaining can be avoided and branch prediction exploited by predicting if a bucket is empty or not. A bucket is probably empty if the probability of it being empty exceeds .5.

Let s represent the size and n the number of keys added. Using the binomial theorem, the probability of a bucket being empty is:

P(0) = C(n, 0) * (1/s)^0 * (1 - 1/s)^(n - 0)

Thus, a bucket is probably empty if there are less than

log(2)/log(s/(s - 1)) keys

As s reaches infinity and if the number of keys added is such that P(0) = .5, then n/s approaches log(2) rapidly:

lim (log(2)/log(s/(s - 1)))/s as s -> infinity = log(2) ~ 0.693...

I've used the open source control at http://dropdowncheckboxes.codeplex.com/ and been very happy with it. My addition was to allow a list of checked files to use just file names instead of full paths if the 'selected' caption gets too long. My addition is called instead of UpdateSelection in your postback handler:

// Update the caption assuming that the items are files<br/> 
// If the caption is too long, eliminate paths from file names<br/> 
public void UpdateSelectionFiles(int maxChars) {
  StringBuilder full = new StringBuilder(); 
  StringBuilder shorter = new StringBuilder();
  foreach (ListItem item in Items) { 
    if (item.Selected) { 
      full.AppendFormat("{0}; ", item.Text);
      shorter.AppendFormat("{0}; ", new FileInfo(item.Text).Name);
    } 
  } 
  if (full.Length == 0) Texts.SelectBoxCaption = "Select...";
  else if (full.Length <= maxChars) Texts.SelectBoxCaption = full.ToString(); 
  else Texts.SelectBoxCaption = shorter.ToString();
} 

Not necessary to use \restylefloat and destroys other options, like caption placement. just use [H] or [!h] after \begin{table}.

UPDATE [TableName]
SET [ColumnName] = Replace([ColumnName], '[StringToRemove]', '[Replacement]')

In your instance it would be

UPDATE [TableName]
SET [ColumnName] = Replace([ColumnName], '[StringToRemove]', '')

Because there is no replacement (you want to get rid of it).

This will run on every row of the specified table. No need for a WHERE clause unless you want to specify only certain rows.

In Python 3.8, the new assignment operator can be used

>>> my_list = [1, 2, 3, 4, 5]
>>> itr = iter(my_list)
>>> a = next(itr)
>>> [(a + (a:=x))/2 for x in itr]
[1.5, 2.5, 3.5, 4.5]

a is a running reference to the previous value in the list, hence it is initialized to the first element of the list and the iteration occurs over the rest of the list, updating a after it is used in each iteration.

An explicit iterator is used to avoid needing to create a copy of the list using my_list[1:].

One major difference between Sequelize and Persistence.js is that the former supports a STRING datatype, i.e. VARCHAR(255). I felt really uncomfortable making everything TEXT.

Try to add empty View inside horizontal LinearLayout before element that you want to see right, e.g.:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <View
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:layout_weight="1" />                

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</LinearLayout>

Another option is the CONCAT command:

SELECT CONCAT(MyTable.TextColumn, 'Text') FROM MyTable

Select * from your_table 
WHERE col1 and col2 and col3 and col4 and col5 IS NOT NULL;

The only disadvantage of this approach is that you can only compare 5 columns, after that the result will always be false, so I do compare only the fields that can be NULL.

Try using "nlargest" on the groupby object. The advantage of using nlargest is that it returns the index of the rows where "the nlargest item(s)" were fetched from. Note: we slice the second(1) element of our index since our index in this case consist of tuples(eg.(s1, 0)).

df = pd.DataFrame({
'sp' : ['MM1', 'MM1', 'MM1', 'MM2', 'MM2', 'MM2', 'MM4', 'MM4','MM4'],
'mt' : ['S1', 'S1', 'S3', 'S3', 'S4', 'S4', 'S2', 'S2', 'S2'],
'val' : ['a', 'n', 'cb', 'mk', 'bg', 'dgb', 'rd', 'cb', 'uyi'],
'count' : [3,2,5,8,10,1,2,2,7]
})

d = df.groupby('mt')['count'].nlargest(1) # pass 1 since we want the max

df.iloc[[i[1] for i in d.index], :] # pass the index of d as list comprehension

enter image description here

Essentially, Provider, Factory, and Service are all Services. A Factory is a special case of a Service when all you need is a $get() function, allowing you to write it with less code.

The major differences among Services, Factories, and Providers are their complexities. Services are the simplest form, Factories are a little more robust, and Providers are configurable at runtime.

Here is a summary of when to use each:

Factory: The value you are providing needs to be calculated based on other data.

Service: You are returning an object with methods.

Provider: You want to be able to configure, during the config phase, the object that is going to be created before it’s created. Use the Provider mostly in the app config, before the app has fully initialized.

I want to share a case, where I think the possibility of having multiple DBContexts in the same database makes good sense.

I have a solution with two database. One is for domain data except user information. The other is solely for user information. This division is primarily driven by the EU General Data Protection Regulation. By having two databases, I can freely move the domain data around (e.g. from Azure to my development environment) as long as the user data stays in one secure place.

Now for the user database I have implemented two schemas through EF. One is the default one provided by the AspNet Identity framework. The other is our own implementing anything else user related. I prefer this solution over extending the ApsNet schema, because I can easily handle future changes to AspNet Identity and at the same time the separation makes it clear to the programmers, that "our own user information" goes in the specific user schema we have defined.

My situation and solution: I had created and enabled a HyperV ethernet adapter. For some reason, my main windows machine was using the "virtual" ethernet adapter instead of the 'hardware' adapter.

I disabled the virtual ethernet and my network settings to change the network public/privacy settings were revealed.

I found this to be the shortest working way to refresh with ui-router:

$state.go($state.current, {}, {reload: true}); //second parameter is for $stateParams

Update for newer versions:

$state.reload();

Which is an alias for:

$state.transitionTo($state.current, $stateParams, { 
  reload: true, inherit: false, notify: true
});

Documentation: https://angular-ui.github.io/ui-router/site/#/api/ui.router.state.$state#methods_reload

For Data access you can use OData. Here is a demo where Scott Hanselman creates an OData front end to StackOverflow database in 30 minutes, with XML and JSON access: Creating an OData API for StackOverflow including XML and JSON in 30 minutes.

For administrative access, like phpMyAdmin package, there is no well established one. You may give a try to IIS Database Manager.

Right Click the User, go to properties, change the default database to master This is the screen print of the image which shows what you have to check if you have the error 19456. Sometimes it default to a database which the user doesn't have permission

This depends entirely on how smart you want the algorithm to be.

For instance, here are some issues:

• cropped images vs. an uncropped image
• images with a text added vs. another without
• mirrored images

The easiest and simplest algorithm I've seen for this is just to do the following steps to each image:

1. scale to something small, like 64x64 or 32x32, disregard aspect ratio, use a combining scaling algorithm instead of nearest pixel
2. scale the color ranges so that the darkest is black and lightest is white
3. rotate and flip the image so that the lighest color is top left, and then top-right is next darker, bottom-left is next darker (as far as possible of course)

Edit A combining scaling algorithm is one that when scaling 10 pixels down to one will do it using a function that takes the color of all those 10 pixels and combines them into one. Can be done with algorithms like averaging, mean-value, or more complex ones like bicubic splines.

Then calculate the mean distance pixel-by-pixel between the two images.

To look up a possible match in a database, store the pixel colors as individual columns in the database, index a bunch of them (but not all, unless you use a very small image), and do a query that uses a range for each pixel value, ie. every image where the pixel in the small image is between -5 and +5 of the image you want to look up.

This is easy to implement, and fairly fast to run, but of course won't handle most advanced differences. For that you need much more advanced algorithms.

I had the same issue, but with a different cause that may help others.

Use a commandprompt in admin mode for this: - TYPE: netsh http show iplisten If there are any IP entries: - TYPE: netsh http delete iplisten Repeat until the list is empty. Check if IIS Express starts now.

Hope this helps, Niels

The accepted answer is correct. I would like to provide an example to elaborate it a bit to those who aren't familiar with promise.

Example:

In my example, I need to replace the src attributes of img tags with different mirror urls if available before rendering the content.

var img_tags = content.querySelectorAll('img');

function checkMirrorAvailability(url) {

    // blah blah 

    return promise;
}

function changeSrc(success, y, response) {
    if (success === true) {
        img_tags[y].setAttribute('src', response.mirror_url);
    } 
    else {
        console.log('No mirrors for: ' + img_tags[y].getAttribute('src'));
    }
}

var promise_array = [];

for (var y = 0; y < img_tags.length; y++) {
    var img_src = img_tags[y].getAttribute('src');

    promise_array.push(
        checkMirrorAvailability(img_src)
        .then(

            // a callback function only accept ONE argument. 
            // Here, we use  `.bind` to pass additional arguments to the
            // callback function (changeSrc).

            // successCallback
            changeSrc.bind(null, true, y),
            // errorCallback
            changeSrc.bind(null, false, y)
        )
    );
}

$q.all(promise_array)
.then(
    function() {
        console.log('all promises have returned with either success or failure!');
        render(content);
    }
    // We don't need an errorCallback function here, because above we handled
    // all errors.
);

Explanation:

From AngularJS docs:

The then method:

then(successCallback, errorCallback, notifyCallback) – regardless of when the promise was or will be resolved or rejected, then calls one of the success or error callbacks asynchronously as soon as the result is available. The callbacks are called with a single argument: the result or rejection reason.

$q.all(promises)

Combines multiple promises into a single promise that is resolved when all of the input promises are resolved.

The promises param can be an array of promises.

About bind(), More info here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/bind

A few steps you have to follow:

• Right click on the project.
• Choose Build Path & then from its menu choose Add Libraries.
• Choose JUnit then click Next.
• Choose JUnit4 then Finish.

This works for me...

While @Eli is quite correct that there usually isn't much of a need to do it, it is possible. savefig takes a bbox_inches argument that can be used to selectively save only a portion of a figure to an image.

Here's a quick example:

import matplotlib.pyplot as plt
import matplotlib as mpl
import numpy as np

# Make an example plot with two subplots...
fig = plt.figure()
ax1 = fig.add_subplot(2,1,1)
ax1.plot(range(10), 'b-')

ax2 = fig.add_subplot(2,1,2)
ax2.plot(range(20), 'r^')

# Save the full figure...
fig.savefig('full_figure.png')

# Save just the portion _inside_ the second axis's boundaries
extent = ax2.get_window_extent().transformed(fig.dpi_scale_trans.inverted())
fig.savefig('ax2_figure.png', bbox_inches=extent)

# Pad the saved area by 10% in the x-direction and 20% in the y-direction
fig.savefig('ax2_figure_expanded.png', bbox_inches=extent.expanded(1.1, 1.2))

The full figure:

Area inside the second subplot:

Area around the second subplot padded by 10% in the x-direction and 20% in the y-direction:

Try sys.path[0].

To quote from the Python docs:

As initialized upon program startup, the first item of this list, path[0], is the directory containing the script that was used to invoke the Python interpreter. If the script directory is not available (e.g. if the interpreter is invoked interactively or if the script is read from standard input), path[0] is the empty string, which directs Python to search modules in the current directory first. Notice that the script directory is inserted before the entries inserted as a result of PYTHONPATH.

To convert a pandas dataframe (df) to a numpy ndarray, use this code:

df.values

array([[nan, 0.2, nan],
       [nan, nan, 0.5],
       [nan, 0.2, 0.5],
       [0.1, 0.2, nan],
       [0.1, 0.2, 0.5],
       [0.1, nan, 0.5],
       [0.1, nan, nan]])

Following Sonar rules, you should whenever you can try to protect yourself, and use System.globalisation whenever it's possible like for DateTime.ToString().

So regarding the other answers you could use:

guid.ToString("", CultureInfo.InvariantCulture)

where "" can be replaces by : N, D, B , P and X for more infos see this comment.

Example here

Easier still: return a pointer to a string that's been malloc'd with strdup.

#include <ncurses.h>

char * getStr(int length)
{   
    char word[length];

    for (int i = 0; i < length; i++)
    {
        word[i] = getch();
    }

    word[i] = '\0';
    return strdup(&word[0]);
}

int main()
{
    char wordd[10];
    initscr();
    *wordd = getStr(10);
    printw("The string is:\n");
    printw("%s\n",*wordd);
    getch();
    endwin();
    return 0;
}

How about this??

from fpdf import FPDF
from PIL import Image
import glob
import os


# set here
image_directory = '/path/to/imageDir'
extensions = ('*.jpg','*.png','*.gif') #add your image extentions
# set 0 if you want to fit pdf to image
# unit : pt
margin = 10

imagelist=[]
for ext in extensions:
    imagelist.extend(glob.glob(os.path.join(image_directory,ext)))

for imagePath in imagelist:
    cover = Image.open(imagePath)
    width, height = cover.size

pdf = FPDF(unit="pt", format=[width + 2*margin, height + 2*margin])
pdf.add_page()

pdf.image(imagePath, margin, margin)

destination = os.path.splitext(imagePath)[0]
pdf.output(destination + ".pdf", "F")

Selectors can be combined:

.bar:nth-child(2)

means "thing that has class bar" that is also the 2nd child.

string[] array = {"USA", "ITLY"};
char[] element1 = array[0].ToCharArray();
// Now for element no 2
char[] element2 = array[1].ToCharArray();

You were missing the small icon. I did the same mistake and the above step resolved it.

As per the official documentation: A Notification object must contain the following:

1. A small icon, set by setSmallIcon()

2. A title, set by setContentTitle()

3. Detail text, set by setContentText()

4. On Android 8.0 (API level 26) and higher, a valid notification channel ID, set by setChannelId() or provided in the NotificationCompat.Builder constructor when creating a channel.

See http://developer.android.com/guide/topics/ui/notifiers/notifications.html

For those of you trying to figure out how to actually remove the styling from the element only, without removing the css from the files, this solution works with jquery:

$('.selector').removeAttr('style');

This will load a file in working directory:

        static void Main(string[] args)
        {
            string fileName = System.IO.Path.GetFullPath(Directory.GetCurrentDirectory() + @"\Yourfile.txt");

            Console.WriteLine("Your file content is:");
            using (StreamReader sr = File.OpenText(fileName))
            {
                string s = "";
                while ((s = sr.ReadLine()) != null)
                {
                    Console.WriteLine(s);
                }
            }

            Console.ReadKey();
        }

If your using console you can also do this.It will prompt the user to write the path of the file(including filename with extension).

        static void Main(string[] args)
        {

            Console.WriteLine("****please enter path to your file****");
            Console.Write("Path: ");
            string pth = Console.ReadLine();
            Console.WriteLine();
            Console.WriteLine("Your file content is:");
            using (StreamReader sr = File.OpenText(pth))
            {
                string s = "";
                while ((s = sr.ReadLine()) != null)
                {
                    Console.WriteLine(s);
                }
            }

            Console.ReadKey();
        }

If you use winforms for example try this simple example:

        private void button1_Click(object sender, EventArgs e)
        {
            string pth = "";
            OpenFileDialog ofd = new OpenFileDialog();

            if (ofd.ShowDialog() == DialogResult.OK)
            {
                pth = ofd.FileName;
                textBox1.Text = File.ReadAllText(pth);
            }
        }

I never had time to play with clojure. But for scala vs groovy, this is words from James Strachan - Groovy creator

"Though my tip though for the long term replacement of javac is Scala. I'm very impressed with it! I can honestly say if someone had shown me the Programming in Scala book by Martin Odersky, Lex Spoon & Bill Venners back in 2003 I'd probably have never created Groovy."

You can read the whole story here

Cautioned and Warned: Yet another kind, functional style.

What is in the link doesn't answer your question directly, but it's trivial to extend it to look like:

static void Main() 
{ 
    Action body = () => { ...your code... };

    body.Catch<InvalidOperationException>() 
        .Catch<BadCodeException>() 
        .Catch<AnotherException>(ex => { ...handler... })(); 
}

(Basically provide another empty Catch overload which returns itself)

The bigger question to this is why. I do not think the cost outweighs the gain here :)

The main concept of partial view is returning the HTML code rather than going to the partial view it self.

[HttpGet]
public ActionResult Calendar(int year)
{
    var dates = new List<DateTime>() { /* values based on year */ };
    HolidayViewModel model = new HolidayViewModel {
        Dates = dates
    };
    return PartialView("HolidayPartialView", model);
}

this action return the HTML code of the partial view ("HolidayPartialView").

To refresh partial view replace the existing item with the new filtered item using the jQuery below.

$.ajax({
                url: "/Holiday/Calendar",
                type: "GET",
                data: { year: ((val * 1) + 1) }
            })
            .done(function(partialViewResult) {
                $("#refTable").html(partialViewResult);
            });

using (FileStream fs = new FileStream("sample.pdf", FileMode.Open, FileAccess.Read))
            {
                byte[] bytes = new byte[fs.Length];
                int numBytesToRead = (int)fs.Length;
                int numBytesRead = 0;
                while (numBytesToRead > 0)
                {
                    // Read may return anything from 0 to numBytesToRead.
                    int n = fs.Read(bytes, numBytesRead, numBytesToRead);

                    // Break when the end of the file is reached.
                    if (n == 0)
                    {
                        break;
                    }

                    numBytesRead += n;
                    numBytesToRead -= n;
                }
                numBytesToRead = bytes.Length;
}

While later versions of Windows have a where command, you can also do this with Windows XP by using the environment variable modifiers, as follows:

c:\> for %i in (cmd.exe) do @echo.   %~$PATH:i
   C:\WINDOWS\system32\cmd.exe

c:\> for %i in (python.exe) do @echo.   %~$PATH:i
   C:\Python25\python.exe

You don't need any extra tools and it's not limited to PATH since you can substitute any environment variable (in the path format, of course) that you wish to use.

And, if you want one that can handle all the extensions in PATHEXT (as Windows itself does), this one does the trick:

@echo off
setlocal enableextensions enabledelayedexpansion

:: Needs an argument.

if "x%1"=="x" (
    echo Usage: which ^<progName^>
    goto :end
)

:: First try the unadorned filenmame.

set fullspec=
call :find_it %1

:: Then try all adorned filenames in order.

set mypathext=!pathext!
:loop1
    :: Stop if found or out of extensions.

    if "x!mypathext!"=="x" goto :loop1end

    :: Get the next extension and try it.

    for /f "delims=;" %%j in ("!mypathext!") do set myext=%%j
    call :find_it %1!myext!

:: Remove the extension (not overly efficient but it works).

:loop2
    if not "x!myext!"=="x" (
        set myext=!myext:~1!
        set mypathext=!mypathext:~1!
        goto :loop2
    )
    if not "x!mypathext!"=="x" set mypathext=!mypathext:~1!

    goto :loop1
:loop1end

:end
endlocal
goto :eof

:: Function to find and print a file in the path.

:find_it
    for %%i in (%1) do set fullspec=%%~$PATH:i
    if not "x!fullspec!"=="x" @echo.   !fullspec!
    goto :eof

It actually returns all possibilities but you can tweak it quite easily for specific search rules.

In your question, you asked for the fastest way to do it. As has been demonstrated repeatedly, particularly with Python, intuition is not a reliable guide: you need to measure.

Here's a simple test of several different implementations:

import sys
from collections import Counter, defaultdict
from itertools import groupby
from operator import itemgetter
from timeit import timeit

L = [1,2,45,55,5,4,4,4,4,4,4,5456,56,6,7,67]

def max_occurrences_1a(seq=L):
    "dict iteritems"
    c = dict()
    for item in seq:
        c[item] = c.get(item, 0) + 1
    return max(c.iteritems(), key=itemgetter(1))

def max_occurrences_1b(seq=L):
    "dict items"
    c = dict()
    for item in seq:
        c[item] = c.get(item, 0) + 1
    return max(c.items(), key=itemgetter(1))

def max_occurrences_2(seq=L):
    "defaultdict iteritems"
    c = defaultdict(int)
    for item in seq:
        c[item] += 1
    return max(c.iteritems(), key=itemgetter(1))

def max_occurrences_3a(seq=L):
    "sort groupby generator expression"
    return max(((k, sum(1 for i in g)) for k, g in groupby(sorted(seq))), key=itemgetter(1))

def max_occurrences_3b(seq=L):
    "sort groupby list comprehension"
    return max([(k, sum(1 for i in g)) for k, g in groupby(sorted(seq))], key=itemgetter(1))

def max_occurrences_4(seq=L):
    "counter"
    return Counter(L).most_common(1)[0]

versions = [max_occurrences_1a, max_occurrences_1b, max_occurrences_2, max_occurrences_3a, max_occurrences_3b, max_occurrences_4]

print sys.version, "\n"

for vers in versions:
    print vers.__doc__, vers(), timeit(vers, number=20000)

The results on my machine:

2.7.2 (v2.7.2:8527427914a2, Jun 11 2011, 15:22:34) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] 

dict iteritems (4, 6) 0.202214956284
dict items (4, 6) 0.208412885666
defaultdict iteritems (4, 6) 0.221301078796
sort groupby generator expression (4, 6) 0.383440971375
sort groupby list comprehension (4, 6) 0.402786016464
counter (4, 6) 0.564319133759

So it appears that the Counter solution is not the fastest. And, in this case at least, groupby is faster. defaultdict is good but you pay a little bit for its convenience; it's slightly faster to use a regular dict with a get.

What happens if the list is much bigger? Adding L *= 10000 to the test above and reducing the repeat count to 200:

dict iteritems (4, 60000) 10.3451900482
dict items (4, 60000) 10.2988479137
defaultdict iteritems (4, 60000) 5.52838587761
sort groupby generator expression (4, 60000) 11.9538850784
sort groupby list comprehension (4, 60000) 12.1327362061
counter (4, 60000) 14.7495789528

Now defaultdict is the clear winner. So perhaps the cost of the 'get' method and the loss of the inplace add adds up (an examination of the generated code is left as an exercise).

But with the modified test data, the number of unique item values did not change so presumably dict and defaultdict have an advantage there over the other implementations. So what happens if we use the bigger list but substantially increase the number of unique items? Replacing the initialization of L with:

LL = [1,2,45,55,5,4,4,4,4,4,4,5456,56,6,7,67]
L = []
for i in xrange(1,10001):
    L.extend(l * i for l in LL)

dict iteritems (2520, 13) 17.9935798645
dict items (2520, 13) 21.8974409103
defaultdict iteritems (2520, 13) 16.8289561272
sort groupby generator expression (2520, 13) 33.853593111
sort groupby list comprehension (2520, 13) 36.1303369999
counter (2520, 13) 22.626899004

So now Counter is clearly faster than the groupby solutions but still slower than the iteritems versions of dict and defaultdict.

The point of these examples isn't to produce an optimal solution. The point is that there often isn't one optimal general solution. Plus there are other performance criteria. The memory requirements will differ substantially among the solutions and, as the size of the input goes up, memory requirements may become the overriding factor in algorithm selection.

Bottom line: it all depends and you need to measure.

Two options:

1) For modern (evergreen) browsers: The "input" event would act as an alternative "change" event.

https://developer.mozilla.org/en-US/docs/Web/Events/input

document.querySelector('div').addEventListener('input', (e) => {
    // Do something with the "change"-like event
});

or

<div oninput="someFunc(event)"></div>

or (with jQuery)

$('div').on('click', function(e) {
    // Do something with the "change"-like event
});

2) To account for IE11 and modern (evergreen) browsers: This watches for element changes and their contents inside the div.

https://developer.mozilla.org/en-US/docs/Web/API/MutationObserver

var div = document.querySelector('div');
var divMO = new window.MutationObserver(function(e) {
    // Do something on change
});
divMO.observe(div, { childList: true, subtree: true, characterData: true });

It is not an import problem. You simply call .dropDuplicates() on a wrong object. While class of sqlContext.createDataFrame(rdd1, ...) is pyspark.sql.dataframe.DataFrame, after you apply .collect() it is a plain Python list, and lists don't provide dropDuplicates method. What you want is something like this:

 (df1 = sqlContext
     .createDataFrame(rdd1, ['column1', 'column2', 'column3', 'column4'])
     .dropDuplicates())

 df1.collect()

You should use ExecuteScalar() (which returns the first row first column) instead of ExecuteNonQuery() (which returns the no. of rows affected).

You should refer differences between executescalar and executenonquery for more details.

Hope it helps!

If you have readonly attribute, blur by itself would not work. Contraption below should do the job.

$('#myInputID').removeAttr('readonly').trigger('blur').attr('readonly','readonly');

Use simple onkeypress event inline.

 <input type="text" name="count"  onkeypress="return /[0-9a-zA-Z]/i.test(event.key)">

This is an area where CSS has never really had any solutions — you’re down to using <table> tags (or faking them using the CSS display:table* values), as that’s the only place where a “keep a bunch of elements the same height” was implemented.

<div style="display: table-row;">

    <div style="border:1px solid #cccccc; display: table-cell;">
        Some content!<br/>
        Some content!<br/>
        Some content!<br/>
        Some content!<br/>
        Some content!<br/>
    </div>

    <div style="border:1px solid #cccccc;  display: table-cell;">
        Some content!
    </div>

</div>

This works in all versions of Firefox, Chrome and Safari, Opera from at least version 8, and in IE from version 8.

For Python 3.x, use input(). For Python 2.x, use raw_input(). Don't forget you can add a prompt string in your input() call to create one less print statement. input("GUESS THAT NUMBER!").

You don't really need an explicit loop to parse multiple matches — pass a replacement function as the second argument as described in: String.prototype.replace(regex, func):

var str = "Our chief weapon is {1}, {0} and {2}!"; _x000D_
var params= ['surprise', 'fear', 'ruthless efficiency'];_x000D_
var patt = /{([^}]+)}/g;_x000D_
_x000D_
str=str.replace(patt, function(m0, m1, position){return params[parseInt(m1)];});_x000D_
_x000D_
document.write(str);

The m0 argument represents the full matched substring {0}, {1}, etc. m1 represents the first matching group, i.e. the part enclosed in brackets in the regex which is 0 for the first match. And position is the starting index within the string where the matching group was found — unused in this case.

if(isset($_GET['content'])){
  $content = $_GET['content'];
  $dir = $_GET['dir'];
  header("Content-type:".$content);
  @readfile($dir);
}

$directory = (file_exists("mydir/"))?"mydir/":die("file/directory doesn't exists");// checks directory if existing.
 //the line above is just a one-line if statement (syntax: (conditon)?code here if true : code if false; )
 if($handle = opendir($directory)){ //opens directory if existing.
   while ($file = readdir($handle)) { //assign each file with link <a> tag with GET params
     echo '<a target="_blank" href="?content=application/pdf&dir='.$directory.'">'.$file.'</a>';
}

}

if you click the link a new window will appear with the pdf file

JavaScript stores strings as UTF-16 (double byte) so if you want to ignore the second byte just strip it out with a bitwise & operator on 0000000011111111 (ie 255):

'a'.charCodeAt(0) & 255 === 97; // because 'a' = 97 0 
'b'.charCodeAt(0) & 255 === 98; // because 'b' = 98 0 
'?'.charCodeAt(0) & 255 === 19; // because '?' = 19 39

Code will be As below.

[textarea id:message 0x0 class:custom-class "Insert text here"]<!-- No Rows No columns -->

[textarea id:message x2 class:custom-class "Insert text here"]<!-- Only Rows -->

[textarea id:message 12x class:custom-class "Insert text here"]<!-- Only Columns -->

[textarea id:message 10x2 class:custom-class "Insert text here"]<!-- Both Rows and Columns -->

Your code is not doing what I think you think it is doing. The line for item in z: will iterate through z, each time making item equal to one single element of z. The original item list is therefore overwritten before you've done anything with it.

I think you want something like this:

item = [0,1,2,3,4,5,6,7,8,9]

for element in item:
    if element not in z:
        print element

But you could easily do this like:

[x for x in item if x not in z]

or (if you don't mind losing duplicates of non-unique elements):

set(item) - set(z)

Making a function static hides it from other translation units, which helps provide encapsulation.

helper_file.c

int f1(int);        /* prototype */
static int f2(int); /* prototype */

int f1(int foo) {
    return f2(foo); /* ok, f2 is in the same translation unit */
                    /* (basically same .c file) as f1         */
}

int f2(int foo) {
    return 42 + foo;
}

main.c:

int f1(int); /* prototype */
int f2(int); /* prototype */

int main(void) {
    f1(10); /* ok, f1 is visible to the linker */
    f2(12); /* nope, f2 is not visible to the linker */
    return 0;
}

There are three ways I am aware of. The first not being the prettiest and the second being the common way in most programming languages:

1. Use another single quote: 'I mustn''t sin!'
2. Use the escape character \ before the single quote': 'I mustn\'t sin!'
3. Use double quotes to enclose string instead of single quotes: "I mustn't sin!"

    DB::statement("your query")

I used it for add index to column in migration

You can create your own conversion function:

    static long ToLong(string lNumber)
    {
        if (string.IsNullOrEmpty(lNumber))
            throw new Exception("Not a number!");
        char[] chars = lNumber.ToCharArray();
        long result = 0;
        bool isNegative = lNumber[0] == '-';
        if (isNegative && lNumber.Length == 1)
            throw new Exception("- Is not a number!");

        for (int i = (isNegative ? 1:0); i < lNumber.Length; i++)
        {
            if (!Char.IsDigit(chars[i]))
            {
                if (chars[i] == '.' && i < lNumber.Length - 1 && Char.IsDigit(chars[i+1]))
                {
                    var firstDigit = chars[i + 1] - 48;
                    return (isNegative ? -1L:1L) * (result + ((firstDigit < 5) ? 0L : 1L));    
                }
                throw new InvalidCastException($" {lNumber} is not a valid number!");
            }
            result = result * 10 + ((long)chars[i] - 48L);
        }
        return (isNegative ? -1L:1L) * result;
    }

It can be improved further:

• performance wise
• make the validation stricter in the sense that it currently doesn't care if characters after first decimal aren't digits
• specify rounding behavior as parameter for conversion function. it currently does rounding

You can change the passphrase for your private key by doing:

ssh-keygen -f ~/.ssh/id_rsa -p

From long to DateTime: new DateTime(long ticks)

From DateTime to long: DateTime.Ticks

As said before, with JPA, in order to have the chance to have extra columns, you need to use two OneToMany associations, instead of a single ManyToMany relationship. You can also add a column with autogenerated values; this way, it can work as the primary key of the table, if useful.

For instance, the implementation code of the extra class should look like that:

@Entity
@Table(name = "USER_SERVICES")
public class UserService{

    // example of auto-generated ID
    @Id
    @Column(name = "USER_SERVICES_ID", nullable = false)
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private long userServiceID;



    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "USER_ID")
    private User user;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "SERVICE_ID")
    private Service service;



    // example of extra column
    @Column(name="VISIBILITY")    
    private boolean visibility;



    public long getUserServiceID() {
        return userServiceID;
    }


    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }

    public Service getService() {
        return service;
    }

    public void setService(Service service) {
        this.service = service;
    }

    public boolean getVisibility() {
        return visibility;
    }

    public void setVisibility(boolean visibility) {
        this.visibility = visibility;
    }

}

From Oracle docs, Date.toString() method convert Date object to a String of the specific form - do not use toString method on Date object. Try to use:

String stringDate = new SimpleDateFormat(YOUR_STRING_PATTERN).format(yourDateObject);

Next step is parse stringDate to Date:

Date date = new SimpleDateFormat(OUTPUT_PATTERN).parse(stringDate);

Note that, parse method throws ParseException

I found the the solution at Expert Exchange, which worked fine for me.

@Bean
public MultipartConfigElement multipartConfigElement() {
    MultipartConfigFactory factory = new MultipartConfigFactory();
    factory.setMaxFileSize("124MB");
    factory.setMaxRequestSize("124MB");
    return factory.createMultipartConfig();
}

A while loop can be simulated in cmd.exe with:

:still_more_files
    if %countfiles% leq 21 (
        rem change countfile here
        goto :still_more_files
    )

For example, the following script:

    @echo off
    setlocal enableextensions enabledelayedexpansion
    set /a "x = 0"

:more_to_process
    if %x% leq 5 (
        echo %x%
        set /a "x = x + 1"
        goto :more_to_process
    )

    endlocal

outputs:

0
1
2
3
4
5

For your particular case, I would start with the following. Your initial description was a little confusing. I'm assuming you want to delete files in that directory until there's 20 or less:

    @echo off
    set backupdir=c:\test

:more_files_to_process
    for /f %%x in ('dir %backupdir% /b ^| find /v /c "::"') do set num=%%x
    if %num% gtr 20 (
        cscript /nologo c:\deletefile.vbs %backupdir%
        goto :more_files_to_process
    )

I had exact issue and here is how I fixed:

I found out that I had first installed Keras then installed pandas in my virtual env. When you install keras, pandas is shipped with it. Do not need to pip install pandas.

I tested this hypothesis by creating new virtual environment and wala... pandas appeared without me installing it. Thus I came to the conclusion that pandas is automatically installed when you pip install keras.

Look at the GeoIP functions under "Other Basic Extensions." http://php.net/manual/en/book.geoip.php

The top answer is flawed in my opinion. Hopefully, no one is mass importing all of pandas into their namespace with from pandas import *. Also, the map method should be reserved for those times when passing it a dictionary or Series. It can take a function but this is what apply is used for.

So, if you must use the above approach, I would write it like this

df["A1"], df["A2"] = zip(*df["a"].apply(calculate))

There's actually no reason to use zip here. You can simply do this:

df["A1"], df["A2"] = calculate(df['a'])

This second method is also much faster on larger DataFrames

df = pd.DataFrame({'a': [1,2,3] * 100000, 'b': [2,3,4] * 100000})

DataFrame created with 300,000 rows

%timeit df["A1"], df["A2"] = calculate(df['a'])
2.65 ms ± 92.4 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

%timeit df["A1"], df["A2"] = zip(*df["a"].apply(calculate))
159 ms ± 5.24 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

60x faster than zip

In general, avoid using apply

Apply is generally not much faster than iterating over a Python list. Let's test the performance of a for-loop to do the same thing as above

%%timeit
A1, A2 = [], []
for val in df['a']:
    A1.append(val**2)
    A2.append(val**3)

df['A1'] = A1
df['A2'] = A2

298 ms ± 7.14 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

So this is twice as slow which isn't a terrible performance regression, but if we cythonize the above, we get much better performance. Assuming, you are using ipython:

%load_ext cython

%%cython
cpdef power(vals):
    A1, A2 = [], []
    cdef double val
    for val in vals:
        A1.append(val**2)
        A2.append(val**3)

    return A1, A2

%timeit df['A1'], df['A2'] = power(df['a'])
72.7 ms ± 2.16 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

Directly assigning without apply

You can get even greater speed improvements if you use the direct vectorized operations.

%timeit df['A1'], df['A2'] = df['a'] ** 2, df['a'] ** 3
5.13 ms ± 320 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

This takes advantage of NumPy's extremely fast vectorized operations instead of our loops. We now have a 30x speedup over the original.

The simplest speed test with apply

The above example should clearly show how slow apply can be, but just so its extra clear let's look at the most basic example. Let's square a Series of 10 million numbers with and without apply

s = pd.Series(np.random.rand(10000000))

%timeit s.apply(calc)
3.3 s ± 57.4 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

Without apply is 50x faster

%timeit s ** 2
66 ms ± 2 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

Give a class or id to the element and use jquery function unbind();

$(".slide_prevent").click(function(){
                $(".slide_prevent").unbind();
              });

We have now (jan2017) a csv layer import inside Google Maps itself.

Google Maps > "Your Places" > "Open in My Maps"

Javascript being dynamic language there a zillion ways to mess up where another language would stop you.

Avoiding a fundamental language feature such as new on the basis that you might mess up is a bit like removing your shiny new shoes before walking through a minefield just in case you might get your shoes muddy.

I use a convention where function names begin with a lower case letter and 'functions' that are actually class definitions begin with a upper case letter. The result is a really quite compelling visual clue that the 'syntax' is wrong:-

var o = MyClass();  // this is clearly wrong.

On top of this good naming habits help. After all functions do things and therefore there should be a verb in its name whereas classes represent objects and are nouns and adjectives with no verb.

var o = chair() // Executing chair is daft.
var o = createChair() // makes sense.

Its interesting how SO's syntax colouring has interpretted the code above.

If you want to disable the Query cache set the 'query_cache_size' to 0 in your mysql configuration file . If its set 0 mysql wont use the query cache.

You must have an application associated with the file type. You must be in the folder that houses the file. In gitbash: start file.extension

I have been having exactly the same problem, and finding almost no information online about it. Nothing at all in the books. Finally I found this sober query on stackoverflow and (ha!) it was the final impetus I needed to set up an account here.

And I have a partial answer, but alas not a complete one.

First of all, realise that the default timeout for getCurrentPosition is infinite(!). That means that your error handler will never be called if getCurrentPosition hangs somewhere on the back end.

To ensure that you get a timeout, add the optional third parameter to your call to getCurrentPosition, for example, if you want the user to wait no more than 10 seconds before giving them a clue what is happening, use:

navigator.geolocation.getCurrentPosition(successCallback,errorCallback,{timeout:10000});

Secondly, I have experienced quite different reliability in different contexts. Here at home, I get a callback within a second or two, although the accuracy is poor.

At work however, I experience quite bizarre variations in behavior: Geolocation works on some computers all the time (IE excepted, of course), others only work in chrome and safari but not firefox (gecko issue?), others work once, then subsequently fail - and the pattern changes from hour to hour, from day to day. Sometimes you have a 'lucky' computer, sometimes not. Perhaps slaughtering goats at full moon would help?

I have not been able to fathom this, but I suspect that the back end infrastructure is more uneven than advertised in the various gung-ho books and websites that are pushing this feature. I really wish that they would be a bit more straight about how flakey this feature is, and how important that timeout setting is, if you want your error handler to work properly.

I have been trying to teach this stuff to students today, and had the embarassing situation where my own computer (on the projector and several large screens) was failing silently, whereas about 80% of the students were getting a result almost instantly (using the exact same wireless network). It's very difficult to resolve these issues when my students are also making typos and other gaffes, and when my own pc is also failing.

Anyway, I hope this helps some of you guys. Thanks for the sanity check!

// thousand separates a digit-only string using commas
// by element:  onkeyup = "ThousandSeparate(this)"
// by ID:       onkeyup = "ThousandSeparate('txt1','lbl1')"
function ThousandSeparate()
{
    if (arguments.length == 1)
    {
        var V = arguments[0].value;
        V = V.replace(/,/g,'');
        var R = new RegExp('(-?[0-9]+)([0-9]{3})'); 
        while(R.test(V))
        {
            V = V.replace(R, '$1,$2');
        }
        arguments[0].value = V;
    }
    else  if ( arguments.length == 2)
    {
        var V = document.getElementById(arguments[0]).value;
        var R = new RegExp('(-?[0-9]+)([0-9]{3})'); 
        while(R.test(V))
        {
            V = V.replace(R, '$1,$2');
        }
        document.getElementById(arguments[1]).innerHTML = V;
    }
    else return false;
}   

Here is a full example, I hope it helps =).

<!DOCTYPE html> 
<html> 
<body> 

<video id="myVideo" controls="controls">
  <source src="your_video_file.mp4" type="video/mp4">
  <source src="your_video_file.mp4" type="video/ogg">
  Your browser does not support HTML5 video.
</video>

<script type='text/javascript'>
    document.getElementById('myVideo').addEventListener('ended',myHandler,false);
    function myHandler(e) {
        if(!e) { e = window.event; }
        alert("Video Finished");
    }
</script>
</body> 
</html>

If you can't/won't use iterators and if you can't/won't use std::size_t for the loop index, make a .size() to int conversion function that documents the assumption and does the conversion explicitly to silence the compiler warning.

#include <cassert>
#include <cstddef>
#include <limits>

// When using int loop indexes, use size_as_int(container) instead of
// container.size() in order to document the inherent assumption that the size
// of the container can be represented by an int.
template <typename ContainerType>
/* constexpr */ int size_as_int(const ContainerType &c) {
    const auto size = c.size();  // if no auto, use `typename ContainerType::size_type`
    assert(size <= static_cast<std::size_t>(std::numeric_limits<int>::max()));
    return static_cast<int>(size);
}

Then you write your loops like this:

for (int i = 0; i < size_as_int(things); ++i) { ... }

The instantiation of this function template will almost certainly be inlined. In debug builds, the assumption will be checked. In release builds, it won't be and the code will be as fast as if you called size() directly. Neither version will produce a compiler warning, and it's only a slight modification to the idiomatic loop.

If you want to catch assumption failures in the release version as well, you can replace the assertion with an if statement that throws something like std::out_of_range("container size exceeds range of int").

Note that this solves both the signed/unsigned comparison as well as the potential sizeof(int) != sizeof(Container::size_type) problem. You can leave all your warnings enabled and use them to catch real bugs in other parts of your code.

To solve this issue on my side, I had to use a combo of what was already proposed there

DECLARE
  chunk1 CLOB; chunk2 CLOB; chunk3 CLOB;
BEGIN
  chunk1 := 'very long literal part 1';
  chunk2 := 'very long literal part 2';
  chunk3 := 'very long literal part 3';

  INSERT INTO table (MY_CLOB)
  SELECT ( chunk1 || chunk2 || chunk3 ) FROM dual;
END;

Hope this helps.

INSERT INTO #TempTable (ID, Date, Name) 
SELECT id, date, name 
FROM physical_table

The equivalent(which keep parent order) to 'git merge -s theirs branchB'

Before merge:

!!! Make sure you are in clean state !!!

Do the merge:

git commit-tree -m "take theirs" -p HEAD -p branchB 'branchB^{tree}'
git reset --hard 36daf519952 # is the output of the prev command

What we did ? We created a new commit which two parents ours and theirs and the contnet of the commit is branchB - theirs

After merge:

More precisely:

git commit-tree -m "take theirs" -p HEAD -p 'SOURCE^{commit}' 'SOURCE^{tree}'

Axivion Bauhaus Suite is a static analysis tool that works with C# (as well as C, C++ and Java).

It provides the following capabilities:

• Software Architecture Visualization (inlcuding dependencies)
• Enforcement of architectural rules e.g. layering, subsystems, calling rules
• Clone Detection - highlighting copy and pasted (and modified code)
• Dead Code Detection
• Cycle Detection
• Software Metrics
• Code Style Checks

These features can be run on a one-off basis or as part of a Continuous Integration process. Issues can be highlighted on a per project basis or per developer basis when the system is integrated with a source code control system.

I seem to have found something that worked for me which no one else mentioned.

# Ignore everything
*

# But not these files...
!.gitignore
!script.pl
!template.latex
# etc...

# And if you want to include a sub-directory and all sub-directory and files under it, but not all sub-directories
!subdir/
!subdir/**/*

Basically, it seems to negate a sub-directory from being ignored, you have to have two entries, one for the sub-directory itself !subdir/ and then another one which expands to all files and folders under it !subdir/**/*

A const to a pointer indicates a "read-only" memory location. Whereas the ones without const are a read-write memory areas. So, you "cannot" convert a const(read-only location) to a normal(read-write) location.

The alternate is to copy the data to a different read-write location and pass this pointer to the required function. You may use strdup() to perform this action.

This is a diff engine for java developers, but it comes with a demo interface - you might be able to use it: https://community.emc.com/docs/DOC-5042

JTextField allows us to getText() and setText() these are used to get and set the contents of the text field, for example.

text = texfield.getText();

hope this helps

After making changes to the pg_hba.conf or postgresql.conf files, the cluster needs to be reloaded to pick up the changes.

From the command line: pg_ctl reload

From within a db (as superuser): select pg_reload_conf();

From PGAdmin: right-click db name, select "Reload Configuration"

Note: the reload is not sufficient for changes like enabling archiving, changing shared_buffers, etc -- those require a cluster restart.

As I can see the code
System.out.println("Managers choice this week" + anyItem + "our recommendation to you");
is unreachable.

if your port is 3307 (based on your port)

Add this line in xampp\phpMyAdmin\config.inc: after i++

$cfg['Servers'][$i]['port'] = '3307';

Bootstrap provide events that you can hook into modal, like if you want to fire a event when the modal has finished being hidden from the user you can use hidden.bs.modal event like this

    /* hidden.bs.modal event example */
    $('#myModal').on('hidden.bs.modal', function () {
          window.alert('hidden event fired!');
    })

Check a working fiddle here read more about modal methods and events here in Documentation

Here's a snippet of hql that we use. (Names have been changed to protect identities)
