I am using mixed solution (php+css).

Containers are needed for:

• div.imgCont2 container needed to rotate;
• div.imgCont1 container needed to zoomOut - width:150%;
• div.imgCont container needed for scrollbars, when image is zoomOut.

.

<?php
    $image_url = 'your image url.jpg';
    $exif = @exif_read_data($image_url,0,true);
    $orientation = @$exif['IFD0']['Orientation'];
?>

<style>
.imgCont{
    width:100%;
    overflow:auto;
}
.imgCont2[data-orientation="8"]{
    transform:rotate(270deg);
    margin:15% 0;
}
.imgCont2[data-orientation="6"]{
    transform:rotate(90deg);
    margin:15% 0;
}
.imgCont2[data-orientation="3"]{
    transform:rotate(180deg);
}
img{
    width:100%;
}
</style>

<div class="imgCont">
  <div class="imgCont1">
    <div class="imgCont2" data-orientation="<?php echo($orientation) ?>">
      <img src="<?php echo($image_url) ?>">
    </div>
  </div>
</div>

If you only want the orientation tag and nothing else and don't like to include another huge javascript library I wrote a little code that extracts the orientation tag as fast as possible (It uses DataView and readAsArrayBuffer which are available in IE10+, but you can write your own data reader for older browsers):

function getOrientation(file, callback) {_x000D_
    var reader = new FileReader();_x000D_
    reader.onload = function(e) {_x000D_
_x000D_
        var view = new DataView(e.target.result);_x000D_
        if (view.getUint16(0, false) != 0xFFD8)_x000D_
        {_x000D_
            return callback(-2);_x000D_
        }_x000D_
        var length = view.byteLength, offset = 2;_x000D_
        while (offset < length) _x000D_
        {_x000D_
            if (view.getUint16(offset+2, false) <= 8) return callback(-1);_x000D_
            var marker = view.getUint16(offset, false);_x000D_

            if (marker == 0xFFE1) _x000D_
            {_x000D_
                if (view.getUint32(offset += 2, false) != 0x45786966) _x000D_
                {_x000D_
                    return callback(-1);_x000D_
                }_x000D_
_x000D_
                var little = view.getUint16(offset += 6, false) == 0x4949;_x000D_

                {_x000D_
                    if (view.getUint16(offset + (i * 12), little) == 0x0112)_x000D_
                    {_x000D_
                        return callback(view.getUint16(offset + (i * 12) + 8, little));_x000D_
                    }_x000D_
                }_x000D_
            }_x000D_
            else if ((marker & 0xFF00) != 0xFF00)_x000D_

    });_x000D_
}

<input id='input' type='file' />

values:

-2: not jpeg
-1: not defined

For those using Typescript, you can use the following code:

export const getOrientation = (file: File, callback: Function) => {
  var reader = new FileReader();

  reader.onload = (event: ProgressEvent) => {

    if (! event.target) {
      return;
    }

    const file = event.target as FileReader;
    const view = new DataView(file.result as ArrayBuffer);

    if (view.getUint16(0, false) != 0xFFD8) {
        return callback(-2);
    }

    const length = view.byteLength
    let offset = 2;

    while (offset < length)
    {
        if (view.getUint16(offset+2, false) <= 8) return callback(-1);
        let marker = view.getUint16(offset, false);
        offset += 2;

        if (marker == 0xFFE1) {
          if (view.getUint32(offset += 2, false) != 0x45786966) {
            return callback(-1);
          }

          let little = view.getUint16(offset += 6, false) == 0x4949;
          offset += view.getUint32(offset + 4, little);
          let tags = view.getUint16(offset, little);
          offset += 2;
          for (let i = 0; i < tags; i++) {
            if (view.getUint16(offset + (i * 12), little) == 0x0112) {
              return callback(view.getUint16(offset + (i * 12) + 8, little));
            }
          }
        } else if ((marker & 0xFF00) != 0xFF00) {
            break;
        }
        else {
            offset += view.getUint16(offset, false);
        }
    }
    return callback(-1);
  };

  reader.readAsArrayBuffer(file);
}

Here is a link to another similar SO question, which has an answer pointing to this good article on "Reading, writing and photo metadata" in .Net.

I usually use pyexiv2 to set exif information in JPG files, but when I import the library in a script QGIS script crash.

I found a solution using the library exif:

https://pypi.org/project/exif/

It's so easy to use, and with Qgis I don,'t have any problem.

In this code I insert GPS coordinates to a snapshot of screen:

from exif import Image
with open(file_name, 'rb') as image_file:
    my_image = Image(image_file)

my_image.make = "Python"
my_image.gps_latitude_ref=exif_lat_ref
my_image.gps_latitude=exif_lat
my_image.gps_longitude_ref= exif_lon_ref
my_image.gps_longitude= exif_lon

with open(file_name, 'wb') as new_image_file:
    new_image_file.write(my_image.get_file())

What does your text file look like?? Each line a record?

You'll have to check out the BULK INSERT statement - that should look something like:

BULK INSERT dbo.YourTableName
FROM 'D:\directory\YourFileName.csv'
WITH
(
  CODEPAGE = '1252',
  FIELDTERMINATOR = ';',
  CHECK_CONSTRAINTS
) 

Here, in my case, I'm importing a CSV file - but you should be able to import a text file just as well.

From the MSDN docs - here's a sample that hopefully works for a text file with one field per row:

BULK INSERT dbo.temp 
   FROM 'c:\temp\file.txt'
   WITH 
      (
         ROWTERMINATOR ='\n'
      )

Seems to work just fine in my test environment :-)

I had a similar need and end up using componentDidMount(), that one is called long after component class constructor (where you can initialize state from props - as an exmple using redux )

Inside componentDidMount you can then invoke your handleChange method for some UI animation or perform any kind of component properties updates required.

As an example I had an issue updating an input checkbox type programatically, that's why I end up using this code, as onChange handler was not firing at component load:

   componentDidMount() {

    // Update checked 
    const checkbox = document.querySelector('[type="checkbox"]');

    if (checkbox) 
      checkbox.checked = this.state.isChecked;
  }

State was first updated in component class constructor and then utilized to update some input component behavior

According to spark documentation "where() is an alias for filter()"

filter(condition) Filters rows using the given condition. where() is an alias for filter().

Parameters: condition – a Column of types.BooleanType or a string of SQL expression.

>>> df.filter(df.age > 3).collect()
[Row(age=5, name=u'Bob')]
>>> df.where(df.age == 2).collect()
[Row(age=2, name=u'Alice')]

>>> df.filter("age > 3").collect()
[Row(age=5, name=u'Bob')]
>>> df.where("age = 2").collect()
[Row(age=2, name=u'Alice')]

Primitives can be converted to objects with @() expression. So the shortest way is to transform int to NSNumber and pick up string representation with stringValue method:

NSString *strValue = [@(myInt) stringValue];

or

NSString *strValue = @(myInt).stringValue;

Do you mean the conversion 011001100110111101101111 ? foo, for example? You just take the binary stream, split it into separate bytes (01100110, 01101111, 01101111) and look up the ASCII character that corresponds to given number. For example, 01100110 is 102 in decimal and the ASCII character with code 102 is f:

$ perl -E 'say 0b01100110'
102
$ perl -E 'say chr(102)'
f

(See what the chr function does.) You can generalize this algorithm and have a different number of bits per character and different encodings, the point remains the same.

Or if you like to mix outputs (stdout & stderr) in one single file you may want to use:

command > merged-output.txt 2>&1

 HashMap<Integer, String> hmap = new HashMap<Integer, String>();
 hmap.put(4, "DD");

The Value mapped to Key 4 is DD

The simple way

Change to the database directory:

cd /var/lib/mysql/

Shut down MySQL... This is important!

/etc/init.d/mysql stop

Okay, this way doesn't work for InnoDB or BDB-Databases.

Rename database:

mv old-name new-name

...or the table...

cd database/

mv old-name.frm new-name.frm

mv old-name.MYD new-name.MYD

mv old-name.MYI new-name.MYI

Restart MySQL

/etc/init.d/mysql start

Done...

OK, this way doesn't work with InnoDB or BDB databases. In this case you have to dump the database and re-import it.

The best solution for you would depend on what you require from your fake enum.

Simple enum:

If you need the enum as only a list of names identifying different items, the solution by Mark Harrison (above) is great:

Pen, Pencil, Eraser = range(0, 3)

Using a range also allows you to set any starting value:

Pen, Pencil, Eraser = range(9, 12)

In addition to the above, if you also require that the items belong to a container of some sort, then embed them in a class:

class Stationery:
    Pen, Pencil, Eraser = range(0, 3)

To use the enum item, you would now need to use the container name and the item name:

stype = Stationery.Pen

Complex enum:

For long lists of enum or more complicated uses of enum, these solutions will not suffice. You could look to the recipe by Will Ware for Simulating Enumerations in Python published in the Python Cookbook. An online version of that is available here.

More info:

PEP 354: Enumerations in Python has the interesting details of a proposal for enum in Python and why it was rejected.

You can set Apache to serve pages from anywhere with any restrictions but it's normally distributed in a more secure form.

Editing your apache files (http.conf is one of the more common names) will allow you to set any folder so it appears in your webroot.

EDIT:

alias myapp c:\myapp\

I've edited my answer to include the format for creating an alias in the http.conf file which is sort of like a shortcut in windows or a symlink under un*x where Apache 'pretends' a folder is in the webroot. This is probably going to be more useful to you in the long term.

It allows servlets to have multiple servlet mappings:

<servlet>
    <servlet-name>Servlet1</servlet-name>
    <servlet-path>foo.Servlet</servlet-path>
</servlet>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/enroll</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/pay</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/bill</url-pattern>
</servlet-mapping>

It allows filters to be mapped on the particular servlet:

<filter-mapping>
    <filter-name>Filter1</filter-name>
    <servlet-name>Servlet1</servlet-name>
</filter-mapping>

Your proposal would support neither of them. Note that the web.xml is read and parsed only once during application's startup, not on every HTTP request as you seem to think.

Since Servlet 3.0, there's the @WebServlet annotation which minimizes this boilerplate:

@WebServlet("/enroll")
public class Servlet1 extends HttpServlet {

To understand those phrases let's look at the couple of things:

typedef double Foo;
void fooFunc(Foo &_bar){ ... }

So that's passing a double by reference.

typedef double* Foo;
void fooFunc(Foo &_bar){ ... }

now it's passing a pointer to a double by reference.

typedef double** Foo;
void fooFunc(Foo &_bar){ ... }

Finally, it's passing a pointer to a pointer to a double by reference. If you think in terms of typedefs like this you'll understand the proper ordering of the & and * plus what it means.

This worked for me Angular cli 6.x:

import {Router} from '@angular/router';

constructor(private artistService: ArtistService, private router: Router) { }

  selectRow(id: number): void{
       this.router.navigate([`./artist-detail/${id}`]);

  }

I think the example is wrong - javax.sql.DataSource doesn't have these properties either. Your DataSource needs to be of the type org.apache.derby.jdbc.ClientDataSource, which should have those properties.

First check the Visual studio version of the developer PC which can publish the solution(project). as shown is for VS 2013

 /p:VisualStudioVersion=12.0

add the above command line to specify what kind of a visual studio version should build the project. As previous answers, this might happen when we are trying to publish only one project, not the whole solution.

So the complete code would be something like this

"C:\Windows\Microsoft.NET\Framework\v4.0.30319\msbuild.exe" "C:\Program Files (x86)\Jenkins\workspace\Jenkinssecondsample\MVCSampleJenkins\MVCSampleJenkins.csproj" /T:Build;Package /p:Configuration=DEBUG /p:OutputPath="obj\DEBUG" /p:DeployIisAppPath="Default Web Site/jenkinsdemoapp" /p:VisualStudioVersion=12.0

If i run the command line : java -Dspring.profiles.active=development -jar yourApplication.jar from my webapplication directory it states that the path is incorrect. So i just defined the profile in manualy in the application.properties file like this :

spring.profiles.active=mysql 

or

spring.profiles.active=postgres

or

spring.profiles.active=mongodb

On android a far easier way is to use this:

import android.util.Log;
String stackTrace = Log.getStackTraceString(exception); 

I needed a solution to convert columns to rows in Microsoft SQL Server, without knowing the colum names (used in trigger) and without dynamic sql (dynamic sql is too slow for use in a trigger).

I finally found this solution, which works fine:

SELECT
    insRowTbl.PK,
    insRowTbl.Username,
    attr.insRow.value('local-name(.)', 'nvarchar(128)') as FieldName,
    attr.insRow.value('.', 'nvarchar(max)') as FieldValue 
FROM ( Select      
          i.ID as PK,
          i.LastModifiedBy as Username,
          convert(xml, (select i.* for xml raw)) as insRowCol
       FROM inserted as i
     ) as insRowTbl
CROSS APPLY insRowTbl.insRowCol.nodes('/row/@*') as attr(insRow)

As you can see, I convert the row into XML (Subquery select i,* for xml raw, this converts all columns into one xml column)

Then I CROSS APPLY a function to each XML attribute of this column, so that I get one row per attribute.

Overall, this converts columns into rows, without knowing the column names and without using dynamic sql. It is fast enough for my purpose.

(Edit: I just saw Roman Pekar answer above, who is doing the same. I used the dynamic sql trigger with cursors first, which was 10 to 100 times slower than this solution, but maybe it was caused by the cursor, not by the dynamic sql. Anyway, this solution is very simple an universal, so its definitively an option).

I am leaving this comment at this place, because I want to reference this explanation in my post about the full audit trigger, that you can find here: https://stackoverflow.com/a/43800286/4160788

void FindMax()
{
    int lessonNum;

    System.out.print("Enter your lesson numbers : ");
    lessonNum = input.nextInt();
    int[] numbers = new int[lessonNum];
    for (int i = 0; i < numbers.length; i++)
    {
        System.out.print("Please enter " + (i + 1) + " number : ");
        numbers[i] = input.nextInt();
    }
    double max = numbers[0];
    for (int i = 1; i < numbers.length; i++)
    {
        if (numbers[i] > max)
        {
            max = numbers[i];
        }
    }
    System.out.println("Maximum number is : " + max);
}

Give the table a class name and then you target the td's with the following:

table.classname td {
    font-size: 90%;
}

Use this method:

Process.Start(String, String)

First argument is an application (explorer.exe), second method argument are arguments of the application you run.

For example:

in CMD:

explorer.exe -p

in C#:

Process.Start("explorer.exe", "-p")

<select name="CCards" id="ccards">
    <option value="0">Select Saved Payment Method:</option>
    <option value="1846">test  xxxx1234</option>
    <option value="1962">test2  xxxx3456</option>
</select>

<script type="text/javascript">

    /** Jquery **/
    var selectedValue = $('#ccards').val();

    //** Regular Javascript **/
    var selectedValue2 = document.getElementById('ccards').value;


</script>

If someone still needs it (like I do).

The specified role_name must be a role that the current session user is a member of. https://www.postgresql.org/docs/10/sql-set-role.html

We need to make the current session user a member of the role:

create role myrole;
set role myrole;
grant myrole to myuser;
set role myrole;

produces:

Role ROLE created.


Error starting at line : 4 in command -
set role myrole
Error report -
ERROR: permission denied to set role "myrole"

Grant succeeded.


Role SET succeeded.

Maybe you mean

select x
from some_table
where some_column is null or some_column = ''

but I can't tell since you didn't really ask a question.

I love Charles.

The free version works fine for me.

Throttling, rerwiting, breakpoints are all awesome features.

Disclaimer: Everything below is only anecdotal and drawn directly from my personal experience. Anyone that feels up to conducting a more empirically rigorous analysis is welcome to carry it out and down vote if I'm. I am also aware that SQL is a declarative language and you're not supposed to have to consider HOW your code is processed when you write it, but, because I value my time, I do.

There are infinite logically equivalent statements, but I'll consider three(ish).

Case 1: Two Comparisons in a standard order (Evaluation order fixed)

A >= MinBound AND A <= MaxBound

Case 2: Syntactic sugar (Evaluation order is not chosen by author)

A BETWEEN MinBound AND MaxBound

Case 3: Two Comparisons in an educated order (Evaluation order chosen at write time)

A >= MinBound AND A <= MaxBound

Or

A <= MaxBound AND A >= MinBound

In my experience, Case 1 and Case 2 do not have any consistent or notable differences in performance as they are dataset ignorant.

However, Case 3 can greatly improve execution times. Specifically, if you're working with a large data set and happen to have some heuristic knowledge about whether A is more likely to be greater than the MaxBound or lesser than the MinBound you can improve execution times noticeably by using Case 3 and ordering the comparisons accordingly.

One use case I have is querying a large historical dataset with non-indexed dates for records within a specific interval. When writing the query, I will have a good idea of whether or not more data exists BEFORE the specified interval or AFTER the specified interval and can order my comparisons accordingly. I've had execution times cut by as much as half depending on the size of the dataset, the complexity of the query, and the amount of records filtered by the first comparison.

For any T object you can do:

return Request.CreateResponse<T>(HttpStatusCode.OK, Tobject);

How to kill a windows service using PID -

1. open command prompt and type netstat -ano
2. find the PID of the ports which are in used, in this case, it will be 8080, 8005,8009. Let's say PID of these ports are 5760.
3. Now Type taskkill /f /pid 5760
4. it will close the PID and ports will be available for use. Now you can start tomcat as normal by Windows services or by eclipse itself.

Thanks

In case you are working with a column with string values, you can use THE VERY USEFUL function series.str.isnumeric() like:

a = pd.Series(['hi','hola','2.31','288','312','1312', '0,21', '0.23'])

What i do is to copy that column to new column, and do a str.replace('.','') and str.replace(',','') then i select the numeric values. and:

a = a.str.replace('.','')
a = a.str.replace(',','') 
a.str.isnumeric()

Out[15]: 0 False 1 False 2 True 3 True 4 True 5 True 6 True 7 True dtype: bool

Good luck all!

can't you just subset the columns in either df first?

[i for i in df.columns if i not in df2.columns]

dfNew = merge(df **[i for i in df.columns if i not in df2.columns]**, df2, left_index=True, right_index=True, how='outer')

You will need to install the Apple Developer Tools. Once you have done that, the easiest thing is to either use the Xcode IDE or use gcc, or nowadays better cc (the clang LLVM compiler), from the command line.

According to Apple's site, the latest version of Xcode (3.2.1) only runs on Snow Leopard (10.6) so if you have an earlier version of OS X you will need to use an older version of Xcode. Your Mac should have come with a Developer Tools DVD which will contain a version that should run on your system. Also, the Apple Developer Tools site still has older versions available for download. Xcode 3.1.4 should run on Leopard (10.5).

This link may help you. Try checking in your manifest for problems. If you can get it to happen again, post your entire stack trace so that we can see what the error actually is.

I've received this error from referencing services located on a WCFHost from my web tier. What worked for me may not apply to everyone, but I'm leaving this answer for those whom it may. The port number for my WCFHost was randomly updated by IIS, I simply had to update the end routes to the svc references in my web config. Problem solved.

Oh, the fun of a snippet!

if (!function_exists('base_url')) {
    function base_url($atRoot=FALSE, $atCore=FALSE, $parse=FALSE){

            $http = isset($_SERVER['HTTPS']) && strtolower($_SERVER['HTTPS']) !== 'off' ? 'https' : 'http';
            $hostname = $_SERVER['HTTP_HOST'];
            $dir =  str_replace(basename($_SERVER['SCRIPT_NAME']), '', $_SERVER['SCRIPT_NAME']);

            $core = preg_split('@/@', str_replace($_SERVER['DOCUMENT_ROOT'], '', realpath(dirname(__FILE__))), NULL, PREG_SPLIT_NO_EMPTY);
            $core = $core[0];

            $tmplt = $atRoot ? ($atCore ? "%s://%s/%s/" : "%s://%s/") : ($atCore ? "%s://%s/%s/" : "%s://%s%s");
            $end = $atRoot ? ($atCore ? $core : $hostname) : ($atCore ? $core : $dir);
            $base_url = sprintf( $tmplt, $http, $hostname, $end );
        }
        else $base_url = 'http://localhost/';

        if ($parse) {
            $base_url = parse_url($base_url);
            if (isset($base_url['path'])) if ($base_url['path'] == '/') $base_url['path'] = '';
        }

        return $base_url;

You can define first the width of the element as 0, floating right, and then on the event that you are about to show it.. it would be like

$('#the_element_to_slide_from_right_left').animate({ width:'your desired width' }, 600);

Simple as that.

I had the same issue. Once I set environment variable NODE_PATH to the location of my modules (/usr/local/node-v0.8.4/node_modules in my case) the problem went away. P.S. NODE_PATH accepts a colon separated list of directories if you need to specify more than one.

If you have intl extension installed, you can use Transliterator::transliterate function to create a slug easily.

<?php
$string = 'Namnet på bildtävlingen';
$slug = \Transliterator::createFromRules(
    ':: Any-Latin;'
    . ':: NFD;'
    . ':: [:Nonspacing Mark:] Remove;'
    . ':: NFC;'
    . ':: [:Punctuation:] Remove;'
    . ':: Lower();'
    . '[:Separator:] > \'-\''
)
    ->transliterate( $string );
echo $slug; // namnet-pa-bildtavlingen
?>

You can also use ng-template, I think that would be more efficient while run time :)

<div ng-if="!test.view; else somethingElse">1</div>
<ng-template #somethingElse>
    <div>2</div>
</ng-template>

Cheers

You could use background-size, as its supported by most browsers (but not all http://caniuse.com/#search=background-size)

background-size : 150% 150%;

Or

You can use a combo of zoom for webkit/ie and transform:scale for Firefox(-moz-) and Opera(-o-) for cross-browser desktop & mobile

[class^="icon-"]{
    display: inline-block;
    background: url('../img/icons/icons.png') no-repeat;
    width: 64px;
    height: 51px;
    overflow: hidden;
    zoom:0.5;
    -moz-transform:scale(0.5);
    -moz-transform-origin: 0 0;
}

.icon-huge{
    zoom:1;
    -moz-transform:scale(1);
    -moz-transform-origin: 0 0;
}

.icon-big{
    zoom:0.60;
    -moz-transform:scale(0.60);
    -moz-transform-origin: 0 0;
}

.icon-small{
    zoom:0.29;
    -moz-transform:scale(0.29);
    -moz-transform-origin: 0 0;
}

Try this

#include <stdio.h>

struct context;

struct funcptrs{
  void (*func0)(struct context *ctx);
  void (*func1)(void);
};

struct context{
    struct funcptrs fps;
}; 

void func1 (void) { printf( "1\n" ); }
void func0 (struct context *ctx) { printf( "0\n" ); }

void getContext(struct context *con){
    con->fps.func0 = func0;  
    con->fps.func1 = func1;  
}

int main(int argc, char *argv[]){
 struct context c;
   c.fps.func0 = func0;
   c.fps.func1 = func1;
   getContext(&c);
   c.fps.func0(&c);
   getchar();
   return 0;
}

<input name="date" type="text" (focus)="focusFunction()" (focusout)="focusOutFunction()">

I think you are confused about how the compiler puts things together. When you use -c flag, i.e. no linking is done, the input is C++ code, and the output is object code. The .o files thus don't mix with -c, and compiler warns you about that. Symbols from object file are not moved to other object files like that.

All object files should be on the final linker invocation, which is not the case here, so linker (called via g++ front-end) complains about missing symbols.

Here's a small example (calling g++ explicitly for clarity):

PROG ?= myprog
OBJS = worker.o main.o

all: $(PROG)

.cpp.o:
        g++ -Wall -pedantic -ggdb -O2 -c -o $@ $<

$(PROG): $(OBJS)
        g++ -Wall -pedantic -ggdb -O2 -o $@ $(OBJS)

There's also makedepend utility that comes with X11 - helps a lot with source code dependencies. You might also want to look at the -M gcc option for building make rules.

That's the correct usage, but perhaps the spaces in the path name are messing things up for some reason.

You may want to run the program under cmd.exe as well so you can see any output from flow.exe that might be indicating an error.

A thread is an independent set of values for the processor registers (for a single core). Since this includes the Instruction Pointer (aka Program Counter), it controls what executes in what order. It also includes the Stack Pointer, which had better point to a unique area of memory for each thread or else they will interfere with each other.

Threads are the software unit affected by control flow (function call, loop, goto), because those instructions operate on the Instruction Pointer, and that belongs to a particular thread. Threads are often scheduled according to some prioritization scheme (although it's possible to design a system with one thread per processor core, in which case every thread is always running and no scheduling is needed).

In fact the value of the Instruction Pointer and the instruction stored at that location is sufficient to determine a new value for the Instruction Pointer. For most instructions, this simply advances the IP by the size of the instruction, but control flow instructions change the IP in other, predictable ways. The sequence of values the IP takes on forms a path of execution weaving through the program code, giving rise to the name "thread".

jQuery Mobile >= 1.4

Create a custom class, e.g. .custom-btn. Note that to override jQM styles without using !important, CSS hierarchy should be respected. .ui-btn.custom-class or .ui-input-btn.custom-class.

.ui-input-btn.custom-btn {
   border:1px solid red;
   text-decoration:none;
   font-family:helvetica;
   color:red;
   background:url(img.png) repeat-x;
}

Add a data-wrapper-class to input. The custom class will be added to input wrapping div.

<input type="button" data-wrapper-class="custom-btn">

Demo

jQuery Mobile <= 1.3

Input button is wrapped by a DIV with class ui-btn. You need to select that div and the input[type="submit"]. Using !important is essential to override Jquery Mobile styles.

Demo

div.ui-btn, input[type="submit"] {
 border:1px solid red !important;
 text-decoration:none !important;
 font-family:helvetica !important;
 color:red !important;
 background:url(../images/btn_hover.png) repeat-x !important;
}

I spent ages trying to fix this. Every solution talks about 'setting options'. I don't know what that means. Finally, I figured it out. You can just include a commented out line at the top of the file /*jshint esversion: 6 */.

Try this, it works for me.

^(00|\+)[1-9]{1}([0-9][\s]*){9,16}$

Even though this question is quite old and there are great answers already, I thought I should put one more which explains 3 different approaches to solve this problem.

1st Approach

Explicitly map DateTime property public virtual DateTime Start { get; set; } to datetime2 in corresponding column in the table. Because by default EF will map it to datetime.

This can be done by fluent API or data annotation.

1. Fluent API

   In DbContext class overide OnModelCreating and configure property Start (for explanation reasons it's a property of EntityClass class).

   protected override void OnModelCreating(DbModelBuilder modelBuilder)
   {
       //Configure only one property 
       modelBuilder.Entity<EntityClass>()
           .Property(e => e.Start)
           .HasColumnType("datetime2");
   
      //or configure all DateTime Preperties globally(EF 6 and Above)
       modelBuilder.Properties<DateTime>()
           .Configure(c => c.HasColumnType("datetime2"));
   }
   

2. Data annotation

   [Column(TypeName="datetime2")]
   public virtual DateTime Start { get; set; }
   

2nd Approach

Initialize Start to a default value in EntityClass constructor.This is good as if for some reason the value of Start is not set before saving the entity into the database start will always have a default value. Make sure default value is greater than or equal to SqlDateTime.MinValue ( from January 1, 1753 to December 31, 9999)

public class EntityClass
{
    public EntityClass()
    {
        Start= DateTime.Now;
    }
    public DateTime Start{ get; set; }
}

3rd Approach

Make Start to be of type nullable DateTime -note ? after DateTime-

public virtual DateTime? Start { get; set; }

.MERGE_MSG.swp is open in your git, you just need to delete this .swp file. In my case I used following command and it worked fine.

rm .MERGE_MSG.swp

Try setting the initial value when you instantiate the form:

form = MyForm(initial={'max_number': '3'})

If you wanna do with a button click and not the other way. You can do it by adding location.href to your button. Here is how I'm using

<button class="btn btn-lg btn-primary" id="submit" onclick="location.href ='/dashboard'" >Go To Dashboard</button>

The button above uses bootstrap classes for styling. Without styling, the simplest code would be

<button onclick="location.href ='/dashboard'" >Go To Dashboard</button>

The /dashboard is my JSP page, If you are using extension too then used /dashboard.jsp

Typeface.js JavaScript Way:

With typeface.js you can embed custom fonts in your web pages so you don't have to render text to images

Instead of creating images or using flash just to show your site's graphic text in the font you want, you can use typeface.js and write in plain HTML and CSS, just as if your visitors had the font installed locally.

What you are doing may be the simplest way, provided your stream stays sequential—otherwise you will have to put a call to sequential() before forEach.

[later edit: the reason the call to sequential() is necessary is that the code as it stands (forEach(targetLongList::add)) would be racy if the stream was parallel. Even then, it will not achieve the effect intended, as forEach is explicitly nondeterministic—even in a sequential stream the order of element processing is not guaranteed. You would have to use forEachOrdered to ensure correct ordering. The intention of the Stream API designers is that you will use collector in this situation, as below.]

An alternative is

targetLongList = sourceLongList.stream()
    .filter(l -> l > 100)
    .collect(Collectors.toList());

Use DATESTR

>> datestr(40189)
ans =
12-Jan-0110

Unfortunately, Excel starts counting at 1-Jan-1900. Find out how to convert serial dates from Matlab to Excel by using DATENUM

>> datenum(2010,1,11)
ans =
      734149
>> datenum(2010,1,11)-40189
ans =
      693960
>> datestr(40189+693960)
ans =
11-Jan-2010

In other words, to convert any serial Excel date, call

datestr(excelSerialDate + 693960)

EDIT

To get the date in mm/dd/yyyy format, call datestr with the specified format

excelSerialDate = 40189;
datestr(excelSerialDate + 693960,'mm/dd/yyyy')
ans =
01/11/2010

Also, if you want to get rid of the leading zero for the month, you can use REGEXPREP to fix things

excelSerialDate = 40189;
regexprep(datestr(excelSerialDate + 693960,'mm/dd/yyyy'),'^0','')
ans =
1/11/2010

sudo curl https://bootstrap.pypa.io/get-pip.py | python

For a private repository, you will need to obtain a Personal Access Token from https://github.com/settings/tokens.

Then use the following curl command to get the details (substituting in values for [token], [owner] and [name]):

curl -u git:[token] https://api.github.com/repos/[owner]/[name] 2> /dev/null | grep size

As mentioned earlier, size may be in MB or KB.

in addition,if you try to use CustomActionBarTheme,make sure there is

<application android:theme="@style/CustomActionBarTheme" ... />

in AndroidManifest.xml

not

<application android:theme="@android:style/CustomActionBarTheme" ... />

If you are looking like me for just updating your project to the latest these is what works form me since Angular 6:

Open the console on your project folder: If you type: ng update then you will get the below message:

        We analyzed your package.json, there are some packages to update:

          Name                               Version                  Command to update
         --------------------------------------------------------------------------------
          @angular/cli                       7.0.7 -> 7.2.2           ng update @angular/cli
          @angular/core                      7.0.4 -> 7.2.1           ng update @angular/core

There might be additional packages that are outdated.
    Run "ng update --all" to try to update all at the same time.

So I usually go straight and do:

ng update --all

Finally you can check your new version:

The simplest answer is:

On whichever method you declare @Transactional the boundary of transaction starts and boundary ends when method completes.

If you are using JPA call then all commits are with in this transaction boundary.

Lets say you are saving entity1, entity2 and entity3. Now while saving entity3 an exception occur, then as enitiy1 and entity2 comes in same transaction so entity1 and entity2 will be rollback with entity3.

Transaction :

1. entity1.save
2. entity2.save
3. entity3.save

Any exception will result in rollback of all JPA transactions with DB.Internally JPA transaction are used by Spring.

I don't often develop in asp.net, however when it comes to loggers I think a lot of best practices are universal. Here are some of my random thoughts on logging that I have learned over the years:

Frameworks

• Use a logger abstraction framework - like slf4j (or roll your own), so that you decouple the logger implementation from your API. I have seen a number of logger frameworks come and go and you are better off being able to adopt a new one without much hassle.
• Try to find a framework that supports a variety of output formats.
• Try to find a framework that supports plugins / custom filters.
• Use a framework that can be configured by external files, so that your customers / consumers can tweak the log output easily so that it can be read by commerical log management applications with ease.
• Be sure not to go overboard on custom logging levels, otherwise you may not be able to move to different logging frameworks.

Logger Output

• Try to avoid XML/RSS style logs for logging that could encounter catastrophic failures. This is important because if the power switch is shut off without your logger writing the closing </xxx> tag, your log is broken.
• Log threads. Otherwise, it can be very difficult to track the flow of your program.
• If you have to internationalize your logs, you may want to have a developer only log in English (or your language of choice).
• Sometimes having the option to insert logging statements into SQL queries can be a lifesaver in debugging situations. Such as:

    -- Invoking Class: com.foocorp.foopackage.FooClass:9021
    SELECT * FROM foo;

• You want class-level logging. You normally don't want static instances of loggers as well - it is not worth the micro-optimization.
• Marking and categorizing logged exceptions is sometimes useful because not all exceptions are created equal. So knowing a subset of important exceptions a head of time is helpful, if you have a log monitor that needs to send notifications upon critical states.
• Duplication filters will save your eyesight and hard disk. Do you really want to see the same logging statement repeated 10^10000000 times? Wouldn't it be better just to get a message like: This is my logging statement - Repeated 100 times

how to convert JTextField to string and string to JTextField in java

If you mean how to get and set String from jTextField then you can use following methods:

String str = jTextField.getText() // get string from jtextfield

and

jTextField.setText(str)  // set string to jtextfield
//or
new JTextField(str)     // set string to jtextfield

You should check JavaDoc for JTextField

To help other bug-hunters. I had this error because the function didn't exist.

I had a spelling error.

TL;DR

1. Use 172.17.0.0/16 as IP address range, not 172.17.0.0/32.
2. Don't use localhost to connect to the PostgreSQL database on your host, but the host's IP instead. To keep the container portable, start the container with the --add-host=database:<host-ip> flag and use database as hostname for connecting to PostgreSQL.
3. Make sure PostgreSQL is configured to listen for connections on all IP addresses, not just on localhost. Look for the setting listen_addresses in PostgreSQL's configuration file, typically found in /etc/postgresql/9.3/main/postgresql.conf (credits to @DazmoNorton).

Long version

172.17.0.0/32 is not a range of IP addresses, but a single address (namly 172.17.0.0). No Docker container will ever get that address assigned, because it's the network address of the Docker bridge (docker0) interface.

When Docker starts, it will create a new bridge network interface, that you can easily see when calling ip a:

$ ip a
...
3: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN 
    link/ether 56:84:7a:fe:97:99 brd ff:ff:ff:ff:ff:ff
    inet 172.17.42.1/16 scope global docker0
       valid_lft forever preferred_lft forever

As you can see, in my case, the docker0 interface has the IP address 172.17.42.1 with a netmask of /16 (or 255.255.0.0). This means that the network address is 172.17.0.0/16.

The IP address is randomly assigned, but without any additional configuration, it will always be in the 172.17.0.0/16 network. For each Docker container, a random address from that range will be assigned.

This means, if you want to grant access from all possible containers to your database, use 172.17.0.0/16.

I find the most valuable feature of .FormulaR1C1 is sheer speed. Versus eg a couple of very large loops filling some data into a sheet, If you can convert what you are doing into a .FormulaR1C1 form. Then a single operation eg myrange.FormulaR1C1 = "my particular formuala" is blindingly fast (can be a thousand times faster). No looping and counting - just fill the range at high speed.

It works fine for me, but it's a little tricky :)

• First open the PuTTY configuration.
• Select the session (right part of the window, Saved Sessions)
• Click Load (now you have loaded Host Name, Port and Connection type)
• Then click Logging (under Session on the left)
• Change whatever settings you want
• Go back to Session window and click the Save button

Now you have settings for this session set (every time you load session it will be logged).

In PostgreSQL 9.6, there's a new option idle_in_transaction_session_timeout which should accomplish what you describe. You can set it using the SET command, e.g.:

SET SESSION idle_in_transaction_session_timeout = '5min';

.project

When a project is created in the workspace, a project description file is automatically generated that describes the project. The sole purpose of this file is to make the project self-describing, so that a project that is zipped up or released to a server can be correctly recreated in another workspace.

.classpath

Classpath specifies which Java source files and resource files in a project are considered by the Java builder and specifies how to find types outside of the project. The Java builder compiles the Java source files into the output folder and also copies the resources into it.

Have you exposed the X-Token from server side using access-control-expose-headers? because not all headers are allowed to be accessed from the client side, you need to expose them from the server side

Also in your frontend, you can use new HTTP module to get a full response using {observe: 'response'} like

http
  .get<any>('url', {observe: 'response'})
  .subscribe(resp => {
    console.log(resp.headers.get('X-Token'));
  });

The problem with taking IEnumerable as a parameter is that it tells callers "I wish to enumerate this". It doesn't tell them how many times you wish to enumerate.

I can change the objects parameter to be List and then avoid the possible multiple enumeration but then I don't get the highest object that I can handle.

The goal of taking the highest object is noble, but it leaves room for too many assumptions. Do you really want someone to pass a LINQ to SQL query to this method, only for you to enumerate it twice (getting potentially different results each time?)

The semantic missing here is that a caller, who perhaps doesn't take time to read the details of the method, may assume you only iterate once - so they pass you an expensive object. Your method signature doesn't indicate either way.

By changing the method signature to IList/ICollection, you will at least make it clearer to the caller what your expectations are, and they can avoid costly mistakes.

Otherwise, most developers looking at the method might assume you only iterate once. If taking an IEnumerable is so important, you should consider doing the .ToList() at the start of the method.

It's a shame .NET doesn't have an interface that is IEnumerable + Count + Indexer, without Add/Remove etc. methods, which is what I suspect would solve this problem.

JoshAdel's solution uses np.newaxis to add a dimension. An alternative is to use reshape() to align the dimensions in preparation for broadcasting.

data = np.array([[1,1,1],[2,2,2],[3,3,3]])
vector = np.array([1,2,3])

data
# array([[1, 1, 1],
#        [2, 2, 2],
#        [3, 3, 3]])
vector
# array([1, 2, 3])

data.shape
# (3, 3)
vector.shape
# (3,)

data / vector.reshape((3,1))
# array([[1, 1, 1],
#        [1, 1, 1],
#        [1, 1, 1]])

Performing the reshape() allows the dimensions to line up for broadcasting:

data:            3 x 3
vector:              3
vector reshaped: 3 x 1

Note that data/vector is ok, but it doesn't get you the answer that you want. It divides each column of array (instead of each row) by each corresponding element of vector. It's what you would get if you explicitly reshaped vector to be 1x3 instead of 3x1.

data / vector
# array([[1, 0, 0],
#        [2, 1, 0],
#        [3, 1, 1]])
data / vector.reshape((1,3))
# array([[1, 0, 0],
#        [2, 1, 0],
#        [3, 1, 1]])

The answer from Alexander refers to complete docs...

Your simple example from the question simply prints out these values with 2 digits - appending leading 0 if necessary.

If you set the x:Name property to each TabItem as:

<TabControl x:Name="MyTab" SelectionChanged="TabControl_SelectionChanged">
    <TabItem x:Name="MyTabItem1" Header="One"/>
    <TabItem x:Name="MyTabItem2" Header="2"/>
    <TabItem x:Name="MyTabItem3" Header="Three"/>
</TabControl>

Then you can access to each TabItem at the event:

private void TabControl_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    if (MyTabItem1.IsSelected)
    // do your stuff
    if (MyTabItem2.IsSelected)
    // do your stuff
    if (MyTabItem3.IsSelected)
    // do your stuff
}

I was facing same error, But I didn't need to change my password.

Just go to bitbucket->preferences->accounts select your account and check if your password is correct.

In my case, my password was messed up. Just corrected my password and it worked.

My simple trick to change background color and color of the text in Popup Menu / Option Menu

<style name="CustomActionBarTheme"
       parent="@android:style/Theme.Holo">
    <item name="android:popupMenuStyle">@style/MyPopupMenu</item>
    <item name="android:itemTextAppearance">@style/TextAppearance</item>
</style>
<!-- Popup Menu Background Color styles -->
<style name="MyPopupMenu" 
       parent="@android:style/Widget.Holo.ListPopupWindow">

</style>
<!-- Popup Menu Text Color styles -->
<style name="TextAppearance">
    <item name="android:textColor">@color/Your_color_for_text</item>
</style>

That's the XOR operator, not the PLUS operator

XOR works bit by bit, without carrying over like PLUS does

1 XOR 1 = 0
1 XOR 0 = 1
0 XOR 0 = 0
0 XOR 1 = 1

<IF>
    <CONDITIONS>
        <CONDITION field="time" from="5pm" to="9pm"></CONDITION>
    </CONDITIONS>
    <RESULTS><...some actions defined.../></RESULTS>
    <ELSE>
        <RESULTS><...some other actions defined.../></RESULTS>        
    </ELSE>
</IF>

Here's my take on it. This will allow you to have multiple conditions.

This is an old, but still relevant question, and while the answers here are helpful no one answer fully addressed both of the OP's questions.

1. Do I have to install ODP.NET and Oracle client on the computer that I want to run my application?

YES - if you are using ODP.NET, Unmanaged. This is the version that you typically install when you choose "Oracle Data Provider for .NET" in the Oracle Client installer (for example). You Download this from Oracle (just google it: Oracle URLs change often).

But If you are using ODP.NET, Managed (and you probably want to use this one this instead) then No, you only need to install (or deploy) ODP.NET, Managed with the app, not the full Oracle Client. See below for details.

2. If yes, is there other way that I don't have to install them but still can run my application?

Yes, there is at least one way. And it is the Managed port of ODP.NET.

Unfortunately the usual workarounds, including ODBC, Microsoft's Oracle Provider for .NET (yes, that old, deprecated one), and the ODP.NET, Unmanaged DLL all require the Oracle client to be installed. It wasn't until our friends at Oracle gave us a nice little (~5MB) DLL that is also Managed. This means no more having to depoy 32-bit and 64-bit versions to go with 32-bit and 64-bit Oracle clients! And no more issues with assembly binding where you build against 10.0.2.1 (or whatever) but your customers install a range of clients from 9i all the way to 12c, including the 'g' ones in the middle) because you can just ship it with your app, and manage it via nuget.

But if you use ODP.NET, Managed which is available as a nuget package, then you do not need to install the Oracle Client. You only need the ODP.NET, Managed DLL. And if you were previously using the ODP.NET, Unmanaged DLL, it is very easy to switch: simply change all your references to the Managed ODP.NET (.csproj files in csharp, etc.), and then change any using statements, for example: using Oracle.DataAccess.Client becomes using Oracle.ManagedDataAccess.Client and that's it! (Unless you were supposedly using some of the more advanced DB management features in the full client that are exposed in the ODP.NET, Unmanaged, which I have not done myself, so good luck with that..). And also nuke all of those annoying assemblyBindingRedirect nodes from your app.config/web.config files and never sweat that junk again!

References:

• ODP.NET Details: http://www.oracle.com/technetwork/topics/dotnet/index-085163.html
• ODP.NET is backward and foward-compatible: http://www.oracle.com/technetwork/topics/dotnet/multipledbs-089665.html
• Advanced Configuration: https://docs.oracle.com/cd/E48297_01/doc/win.121/e41125/featConfig.htm

Troubleshooting:

That error typically means ODP.NET was found OK, but Oracle client was not found or not installed. This could also occur when the architecture doesn't match (32-bit Oracle client is installed, but trying to use 64-bit Unmanaged ODP.NET, or vice versa). This can also happen due to permissions issues and path issues and other problems with the app domain (your web app or your EXE or whatever) not being able to find the Oracle DLLs to actually communicate with Oracle over the network (the ODP.NET Unmanaged DLLs are basically just wrappers for this that hook into ADO and stuff).

Common solutions I have found to this problem:

App is 64-bit?

• Install 64-bit Oracle Client (32-bit one wont work)

App is 32-bit?

• Install 32-bit Oracle Client (64-bit one wont work)

Oracle Client is already installed for the correct architecture?

• Verify your environment PATH and ORACLE_HOME variables, make sure Oracle can be found (newer versions may use Registry instead)
• Verify the ORACLE_HOME and settings in the Registry (And remember: Registry is either 32-bit or 64-bit, so make sure you check the one that matches your app!)
• Verify permissions on the ORACLE_HOME folder. If you don't know where this is, check the Registry. I have seen cases where ASP.NET app worker process was using Network Service user and for some reason installing 32-bit and 64-bit clients side by side resulted in the permissions being removed from the first client for the Authorized Users group.. fixing perms on the home folder fixed this.
• As always, it is handy to Use SysInternals Process Monitor to find out what file is missing or can't be read.

I have replace your Code and it works well

$sum=0;
while ($row = mysql_fetch_assoc($result)){
    $value = $row['Value'];

    $sum += $value;
}

echo $sum;

This code work for me. I also handled case "Never Ask Me"

I just do it like this:

CvCapture *capture = cvCreateFileCapture("rtsp://camera-address");

Also make sure this dll is available at runtime else cvCreateFileCapture will return NULL

opencv_ffmpeg200d.dll

The camera needs to allow unauthenticated access too, usually set via its web interface. MJPEG format worked via rtsp but MPEG4 didn't.

Your code compiles just fine. However, your array initialization line is wrong:

int array[]={};

What this does is declare an array with a size equal to the number of elements in the brackets. Since there is nothing in the brackets, you're saying the size of the array is 0 - this renders the array completely useless, since now it can't store anything.

Instead, you can either initialize the array right in your original line:

int array[] = { 5, 5, 5, 5 };

Or you can declare the size and then populate it:

int array[] = new int[4];
// ...while loop

If you don't know the size of the array ahead of time (for example, if you're reading a file and storing the contents), you should use an ArrayList instead, because that's an array that grows in size dynamically as more elements are added to it (in layman's terms).

if you have multiple webview, localstorage does not work correctly.
two suggestion:

1. using java database instead webview localstorage that " @Guillaume Gendre " explained.(of course it does not work for me)
2. local storage work like json,so values store as "key:value" .you can add your browser unique id to it's key and using normal android localstorage

I changed this:

public string ByteArrToString(byte[] byteArr)
{
    byte val;
    string tempStr = "";
    for (int i = 0; i <= byteArr.GetUpperBound(0); i++)
    {
        val = byteArr[i];
        if (val < (byte)10)
            tempStr += "00" + val.ToString();
        else if (val < (byte)100)
            tempStr += "0" + val.ToString();
        else
            tempStr += val.ToString();
    }
    return tempStr;
}

to this:

    public string ByteArrToString(byte[] byteArr)
    {
        string temp = "";
        foreach (byte b in byteArr)
            temp += b.ToString().PadLeft(3, '0');
        return temp;
    }

It can function as a good "middle man" between your ORM and your tables.

Example:

We had a Person table that we needed to change the structure on it so the column SomeColumn was going to be moved to another table and would have a one to many relationship to.

However, the majority of the system, with regards to the Person, still used the SomeColumn as a single thing, not many things. We used a view to bring all of the SomeColumns together and put it in the view, which worked out nicely.

This worked because the data layer had changed, but the business requirement hadn't fundamentally changed, so the business objects didn't need to change. If the business objects had to change I don't think this would have been a viable solution, but views definitely function as a good mid point.

Use the in keyword.

if 'apples' in d:
    if d['apples'] == 20:
        print('20 apples')
    else:
        print('Not 20 apples')

If you want to get the value only if the key exists (and avoid an exception trying to get it if it doesn't), then you can use the get function from a dictionary, passing an optional default value as the second argument (if you don't pass it it returns None instead):

if d.get('apples', 0) == 20:
    print('20 apples.')
else:
    print('Not 20 apples.')

The restrict option is typically set to:

• 'A' - only matches attribute name
• 'E' - only matches element name
• 'C' - only matches class name
• 'M' - only matches comment

Here is the documentation link.

If you are moving branches to a new repo from an old one and do NOT have all the old repo branches local, you will need to track them first.

for remote in `git branch -r | grep -v '\->'`; do git branch --track $remote; done

Then add your new remote repo:

git remote add bb <path-to-new-repo>

Then you can push all using this command:

git push -u bb --all

Or you can configure the repo using the git config commands noted in the other responses here if you are not doing this one time or are only looking to move local branches.

The important point, the other responses only push all LOCAL branches. If the branches only exist on an alternate REMOTE repository they will not move without tracking them first. The for loop presented here will help with that.

The existing solutions fail when there are multiple parts to an extension. The function below works for multiple parts, a full path or just a a filename:

function removeExt($path)
{
    $basename = basename($path);
    return strpos($basename, '.') === false ? $path : substr($path, 0, - strlen($basename) + strlen(explode('.', $basename)[0]));
}

echo removeExt('https://example.com/file.php');
// https://example.com/file
echo removeExt('https://example.com/file.tar.gz');
// https://example.com/file
echo removeExt('file.tar.gz');
// file
echo removeExt('file');
// file

I did not add any dependencies, I just change the way I was consuming them.

Preview code

(Uncomment this code if you are using elastic search version < 7.0)

IndexRequest indexRequest = new IndexRequest(
  "twitter",
  "tweets",
  id // this is to make our consumer idempotent
).source(record.value(), XContentType.JSON);

Current code

IndexRequest indexRequest = new IndexRequest("tweets")
  .source(record.value(), XContentType.JSON)
  .id(id); // this is to make our consumer idempotent

I am using bulkrequest and with that I remove that error.

ARM is a RISC (Reduced Instruction Set Computing) architecture while x86 is a CISC (Complex Instruction Set Computing) one.

The core difference between those in this aspect is that ARM instructions operate only on registers with a few instructions for loading and saving data from / to memory while x86 can operate directly on memory as well. Up until v8 ARM was a native 32 bit architecture, favoring four byte operations over others.

So ARM is a simpler architecture, leading to small silicon area and lots of power save features while x86 becoming a power beast in terms of both power consumption and production.

About question on "Is the x86 Architecture specially designed to work with a keyboard while ARM expects to be mobile?". x86 isn't specially designed to work with a keyboard neither ARM for mobile. However again because of the core architectural choices actually x86 also has instructions to work directly with IO while ARM has not. However with specialized IO buses like USBs, need for such features are also disappearing.

If you need a document to quote, this is what Cortex-A Series Programmers Guide (4.0) tells about differences between RISC and CISC architectures:

An ARM processor is a Reduced Instruction Set Computer (RISC) processor.

Complex Instruction Set Computer (CISC) processors, like the x86, have a rich instruction set capable of doing complex things with a single instruction. Such processors often have significant amounts of internal logic that decode machine instructions to sequences of internal operations (microcode).

RISC architectures, in contrast, have a smaller number of more general purpose instructions, that might be executed with significantly fewer transistors, making the silicon cheaper and more power efficient. Like other RISC architectures, ARM cores have a large number of general-purpose registers and many instructions execute in a single cycle. It has simple addressing modes, where all load/store addresses can be determined from register contents and instruction fields.

ARM company also provides a paper titled Architectures, Processors, and Devices Development Article describing how those terms apply to their bussiness.

An example comparing instruction set architecture:

For example if you would need some sort of bytewise memory comparison block in your application (generated by compiler, skipping details), this is how it might look like on x86

repe cmpsb         /* repeat while equal compare string bytewise */

while on ARM shortest form might look like (without error checking etc.)

top:
ldrb r2, [r0, #1]! /* load a byte from address in r0 into r2, increment r0 after */
ldrb r3, [r1, #1]! /* load a byte from address in r1 into r3, increment r1 after */
subs r2, r3, r2    /* subtract r2 from r3 and put result into r2      */
beq  top           /* branch(/jump) if result is zero                 */

which should give you a hint on how RISC and CISC instruction sets differ in complexity.

In your broadcast receiver you could access a view via inflation a root layout from XML resource and then find all your views from this root layout with findViewByid():

View view = View.inflate(context, R.layout.ROOT_LAYOUT, null);

Now you can access your views via 'view' and cast them to your view type:

myImage = (ImageView) view.findViewById(R.id.my_image);

(I just got this working, with my main issue being that I don't have a real internet hostname, so answering this question in case it helps someone)

You need to specify a hostname with HELO. Even so, you should get an error, so Postfix is probably not running.

Also, the => is not a command. The '.' on a single line without any text around it is what tells Postfix that the entry is complete. Here are the entries I used:

telnet localhost 25
(says connected)
EHLO howdy.com
(returns a bunch of 250 codes)
MAIL FROM: [email protected]
RCPT TO: (use a real email address you want to send to)
DATA (type whatever you want on muliple lines)
. (this on a single line tells Postfix that the DATA is complete)

You should get a response like:

250 2.0.0 Ok: queued as 6E414C4643A

The email will probably end up in a junk folder. If it is not showing up, then you probably need to setup the 'Postfix on hosts without a real Internet hostname'. Here is the breakdown on how I completed that step on my Ubuntu box:

sudo vim /etc/postfix/main.cf
smtp_generic_maps = hash:/etc/postfix/generic (add this line somewhere)
(edit or create the file 'generic' if it doesn't exist)
sudo vim /etc/postfix/generic
(add these lines, I don't think it matters what names you use, at least to test)
[email protected]             [email protected]
[email protected]             [email protected]
@localdomain.local                [email protected]
then run:
postmap /etc/postfix/generic (this needs to be run whenever you change the 
generic file)

Happy Trails

How about this:

<command> > <filename.txt> & <filename.txt>

Example:

ipconfig /all > network.txt & network.txt

This will give the results in Notepad instead of the command prompt.

Your Service/ Application might already be running. In Search enter Services and you will get list of services. Stop yours and then try again.

Remove your items from your custom adapter and call notifyDataSetChanged().

I could use the GetBody from Request package.

Look this comment in source code from request.go in net/http:

GetBody defines an optional func to return a new copy of Body. It is used for client requests when a redirect requires reading the body more than once. Use of GetBody still requires setting Body. For server requests it is unused."

GetBody func() (io.ReadCloser, error)

This way you can get the body request without make it empty.

Sample:

getBody := request.GetBody
copyBody, err := getBody()
if err != nil {
    // Do something return err
}
http.DefaultClient.Do(request)

Direct Javascript calls between frames and/or windows are only allowed if they conform to the same-origin policy. If your window and iframe share a common parent domain you can set document.domain to "domain lower") one or both such that they can communicate. Otherwise you'll need to look into something like the postMessage() API.

All title nodes with zipcode or book node as parent:

Version 1:

//title[parent::zipcode|parent::book]

Version 2:

//bookstore/book/title|//bookstore/city/zipcode/title

Version 3: (results are sorted based on source data rather than the order of book then zipcode)

//title[../../../*[book or magazine] or ../../../../*[city/zipcode]]

or - used within true/false - a Boolean operator in xpath

| - a Union operator in xpath that appends the query to the right of the operator to the result set from the left query.

A quick hack that may suit your needs..

Take off the frame of the box and manually position the two legends next to each other. Something like this..

ax1.legend(loc = (.75,.1), frameon = False)
ax2.legend( loc = (.75, .05), frameon = False)

Where the loc tuple is left-to-right and bottom-to-top percentages that represent the location in the chart.

Here is how I do a Subview on iOS in Swift -

class CustomSubview : UIView {

    init() {
        super.init(frame: UIScreen.mainScreen().bounds);

        let windowHeight : CGFloat = 150;
        let windowWidth  : CGFloat = 360;

        self.backgroundColor = UIColor.whiteColor();
        self.frame = CGRectMake(0, 0, windowWidth, windowHeight);
        self.center = CGPoint(x: UIScreen.mainScreen().bounds.width/2, y: 375);

        //for debug validation
        self.backgroundColor = UIColor.grayColor();
        print("My Custom Init");

        return;
    }

    required init?(coder aDecoder: NSCoder) { fatalError("init(coder:) has not been implemented"); }
}

If you wot hard code :)

bool strCanBeInt(std::string string){
    for (char n : string) {
        if (n != '0' && n != '1' && n != '2' && n != '3' && n != '4' && n != '5'
            && n != '6' && n != '7' && n != '8' && n != '9') {
            return false;
        }
    }
    return true;
}

int strToInt(std::string string) {
    int integer = 0;
    int numInt;
    for (char n : string) {
        if(n == '0') numInt = 0;
        if(n == '1') numInt = 1;
        if(n == '2') numInt = 2;
        if(n == '3') numInt = 3;
        if(n == '4') numInt = 4;
        if(n == '5') numInt = 5;
        if(n == '6') numInt = 6;
        if(n == '7') numInt = 7;
        if(n == '8') numInt = 8;
        if(n == '9') numInt = 9;
        if (integer){
            integer *= 10;
        }
        integer += numInt;
    }
    return integer;
}

This piece of code compares two lists both containing a field for a CultureCode like 'en-GB'. This will leave non existing translations in the list. (we needed a dropdown list for not-translated languages for articles)

var compared = supportedLanguages.Where(sl => !existingTranslations.Any(fmt => fmt.CultureCode == sl.Culture)).ToList();

One more validation without re:

def validip(ip):
    return ip.count('.') == 3 and  all(0<=int(num)<256 for num in ip.rstrip().split('.'))

for i in ('123.233.42.12','3234.23.453.353','-2.23.24.234','1.2.3.4'):
    print i,validip(i)

This creates a "See Also" heading containing the link, i.e.:

/**
 * @see <a href="http://google.com">http://google.com</a>
 */

will render as:

See Also:
           http://google.com

whereas this:

/**
 * See <a href="http://google.com">http://google.com</a>
 */

will create an in-line link:

See http://google.com

Once you have selected the highest value, which is "12" in my example, you can then declare it as integer and increment your value:

$FileList = "1", "2", "11"
$foldername = [int]$FileList[2] + 1
$foldername

I tried pretty much everything suggested in the answers above. Unfortunately, nothing worked. Then I signout out of my Github account on VS Code and signed in again. Added the remote origin with the following command.

git remote add origin https://github.com/pete/first_app.git

And it was working.

The specific way to run it depends on whether you gave the image a tag/name or not.

$ docker images
REPOSITORY          TAG                 ID                  CREATED             SIZE
ubuntu              12.04               8dbd9e392a96        4 months ago        131.5 MB (virtual 131.5 MB)

With a name (let's use Ubuntu):

$ docker run -i -t ubuntu:12.04 /bin/bash

Without a name, just using the ID:

$ docker run -i -t 8dbd9e392a96 /bin/bash

Please see Docker run reference for more information.

HttpClient-4.5,Use TLSv1.2 ,You must code like this:

 //Set the https use TLSv1.2
private static Registry<ConnectionSocketFactory> getRegistry() throws KeyManagementException, NoSuchAlgorithmException {
    SSLContext sslContext = SSLContexts.custom().build();
    SSLConnectionSocketFactory sslConnectionSocketFactory = new SSLConnectionSocketFactory(sslContext,
            new String[]{"TLSv1.2"}, null, SSLConnectionSocketFactory.getDefaultHostnameVerifier());
    return RegistryBuilder.<ConnectionSocketFactory>create()
            .register("http", PlainConnectionSocketFactory.getSocketFactory())
            .register("https", sslConnectionSocketFactory)
            .build();
}

        clientConnectionManager.setMaxTotal(100);
        clientConnectionManager.setDefaultMaxPerRoute(20);
        HttpClient client = HttpClients.custom().setConnectionManager(clientConnectionManager).build();
        //Then you can do : client.execute(HttpGet or HttpPost);
    } catch (KeyManagementException | NoSuchAlgorithmException e) {
        e.printStackTrace();
    }
}

It's weird but clean project and rebuild project worked for me.

You cannot return value after resolving promise. Instead call another function when promise is resolved:

function justTesting() {
    promise.then(function(output) {
        // instead of return call another function
        afterResolve(output + 1);
    });
}

function afterResolve(result) {
    // do something with result
}

var test = justTesting();

This should work on most databases. You can also select a blank string as your extra column like so:

Select
  Hat, Show, Boat, '' as SomeValue
From
  Objects

fade the other in in the callback of fadeout, which runs when fadeout is done. Using your code:

$('#two, #three').hide();
$('.slide').click(function(){
    var $this = $(this);
    $this.fadeOut(function(){ $this.next().fadeIn(); });
});

alternatively, you can just "pause" the chain, but you need to specify for how long:

$(this).fadeOut().next().delay(500).fadeIn();

This did it for me simply and perfectly.

Excellent explanation by Scott Robinson

From image to base64 string

let buff = fs.readFileSync('stack-abuse-logo.png');
let base64data = buff.toString('base64');

From base64 string to image

let buff = new Buffer(data, 'base64');
fs.writeFileSync('stack-abuse-logo-out.png', buff);

You could create a new List and addAll() of your other Lists to it. Then return an unmodifiable list with Collections.unmodifiableList().

Your server is imposing some resource limit that your site is hitting. This is usually RAM, CPU, or INODES.

Ask your server administrator what the limits are and what it is you are hitting to solve.

DECLARE @dt1 datetime='2012/06/13 08:11:12', @dt2 datetime='2012/06/12 02:11:12'

SELECT CAST((@dt2-@dt1) as time(0))

IPHostEntry ipHostInfo = Dns.GetHostEntry(serverName);
IPAddress ipAddress = ipHostInfo.AddressList
    .FirstOrDefault(a => a.AddressFamily == AddressFamily.InterNetwork);

You haven't created an event. To do that write:

public event EventHandler<Progress> Progress;

Then, you can call Progress from within the class where it was declared like normal function or delegate:

Progress(this, new Progress("some status"));

So, if you want to report progress in TestClass, the event should be in there too and it should be also static. You can the subscribe to it from your form like this:

TestClass.Progress += SetStatus;

Also, you should probably rename Progress to ProgressEventArgs, so that it's clear what it is.

I'm just posting this since Chrome changes alot, and none of the answers were quite up to date.

1. Open dev tools
2. REFRESH YOUR PAGE (so that the WS connection is captured by the network tab)
3. Click your request
4. Click the "Frames" sub-tab
5. You should see somthing like this:

Try the notepad++ plugin JSMinNpp(Changed name to JSTool since 1.15)

http://www.sunjw.us/jsminnpp/

//this is only good in .NET 4
//read your file:
List<string> ReadFile = File.ReadAllLines(@"C:\TEMP\FILE.TXT").ToList();

//manipulate data here
foreach(string line in ReadFile)
{
    //do something here
}

//write back to your file:
File.WriteAllLines(@"C:\TEMP\FILE2.TXT", ReadFile);

I was taught that for arrays, length is not retrieved through a method due to the following fear: programmers would just assign the length to a local variable before entering a loop (think a for loop where the conditional uses the array's length.) The programmer would supposedly do so to trim down on function calls (and thereby improve performance.) The problem is that the length might change during the loop, and the variable wouldn't.

Another case to use a multi line function would be to circumvent sql server from pushing down the where clause.

For example, I have a table with a table names and some table names are formatted like C05_2019 and C12_2018 and and all tables formatted that way have the same schema. I wanted to merge all that data into one table and parse out 05 and 12 to a CompNo column and 2018,2019 into a year column. However, there are other tables like ACA_StupidTable which I cannot extract CompNo and CompYr and would get a conversion error if I tried. So, my query was in two part, an inner query that returned only tables formatted like 'C_______' then the outer query did a sub-string and int conversion. ie Cast(Substring(2, 2) as int) as CompNo. All looks good except that sql server decided to put my Cast function before the results were filtered and so I get a mind scrambling conversion error. A multi statement table function may prevent that from happening, since it is basically a "new" table.

Also try System.currentTimeMillis()

<div id="music">
<audio autoplay>
  <source src="kooche.mp3" type="audio/mpeg">
  <p>If you can read this, your browser does not support the audio element.</p>
</audio>
</div>

And the css:

#music {
  display:none;
}

Like suggested above, you probably should have the controls available in some form. Maybe use a toggle link/checkbox that slides the controls in via jquery.

The accepted answer from Thorn007 doesn't work when the image is too small.

To solve this, I added a scale factor. This way, it makes the image bigger and it fills the div container.

Example:

<div style="width:400px; height:200px;">
  <img src="pix.jpg" style="max-width:100px; height:50px; transform:scale(4); transform-origin:left top;" />
</div>

Notes:

1. For WebKit you must add -webkit-transform:scale(4); -webkit-transform-origin:left top; in the style.
2. With a scale factor of 4, you have max-width = 400/4 = 100 and max-height = 200/4 = 50
3. An alternate solution is to set max-width and max-height at 25%. It's even simpler.

This worked for me 1.First uninstall create-react-app globally by this command:

npm uninstall -g create-react-app

If there you still have the previous installation please delete the folder called my app completely.(Make sure no program is using that folder including your terminal or cmd promt)

2.then in your project directory:

npm install create-react-app@latest

3.finally:

npx create-react-app my-app

The Google Play Store doesn't provide this data, so the sites must just be scraping it.

Find the location of the .bash_profile file and enter the following into the file:

setterm -blength 0

Which will set the amount of time the beep happens to 0 and thus no beep.

private int[] data = new int[3];

This already initializes your array elements to 0. You don't need to repeat that again in the constructor.

In your constructor it should be:

data = new int[]{0, 0, 0};

The pattern must have delimiters. Delimiters can be a forward slash (/) or any non alphanumeric characters(#,$,*,...). Examples

$pattern = "/My name is '(.*)' and im fine/"; 
$pattern = "#My name is '(.*)' and im fine#";
$pattern = "@My name is '(.*)' and im fine@";  

function timeformat(date1) {
  var date=new Date(date1);
  var month = date.toLocaleString('en-us', { month: 'long' });
  var mdate  =date.getDate();
  var year  =date.getFullYear();
  var hours = date.getHours();
  var minutes = date.getMinutes();
  var ampm = hours >= 12 ? 'pm' : 'am';
  hours = hours % 12;
  hours = hours ? hours : 12; // the hour '0' should be '12'
  minutes = minutes < 10 ? '0'+minutes : minutes;
  var strTime = mdate+"-"+month+"-"+year+" "+hours + ':' + minutes + ' ' + ampm;
  return strTime;
}
var ampm=timeformat("2019-01-11 12:26:43");
console.log(ampm);

Example for how one might use the Stopwatch class in VB.NET.

Dim Stopwatch As New Stopwatch

Stopwatch.Start()
            ''// Test Code
Stopwatch.Stop()
Console.WriteLine(Stopwatch.Elapsed.ToString)

Stopwatch.Restart()            
           ''// Test Again

Stopwatch.Stop()
Console.WriteLine(Stopwatch.Elapsed.ToString)

in your server side the code looks like:

var request = require('request');

app.post('/add', function(req, res){
  console.log(req.body);
  request.post(
    {
    url:'http://localhost:6001/add',
    json: {
      unit_name:req.body.unit_name,
      unit_price:req.body.unit_price
        },
    headers: {
        'Content-Type': 'application/json'
    }
    },
  function(error, response, body){
    // console.log(error);
    // console.log(response);
    console.log(body);
    res.send(body);
  });
  // res.send("body");
});

in receiving end server code looks like:

app.post('/add', function(req, res){
console.log('received request')
console.log(req.body);
let adunit = new AdUnit(req.body);
adunit.save()
.then(game => {
res.status(200).json({'adUnit':'AdUnit is added successfully'})
})
.catch(err => {
res.status(400).send('unable to save to database');
})
});

Schema is just two properties unit_name and unit_price.

I got an error: 'a not found' using the suggested code:

from pyspark.sql.functions import col df1.alias('a').join(df2.alias('b'),col('b.id') == col('a.id')).select([col('a.'+xx) for xx in a.columns] + [col('b.other1'),col('b.other2')])

I changed a.columns to df1.columns and it worked out.

CSS-Transforms are not possible to animate with jQuery, yet. You can do something like this:

function AnimateRotate(angle) {
    // caching the object for performance reasons
    var $elem = $('#MyDiv2');

    // we use a pseudo object for the animation
    // (starts from `0` to `angle`), you can name it as you want
    $({deg: 0}).animate({deg: angle}, {
        duration: 2000,
        step: function(now) {
            // in the step-callback (that is fired each step of the animation),
            // you can use the `now` paramter which contains the current
            // animation-position (`0` up to `angle`)
            $elem.css({
                transform: 'rotate(' + now + 'deg)'
            });
        }
    });
}

You can read more about the step-callback here: http://api.jquery.com/animate/#step

http://jsfiddle.net/UB2XR/23/

And, btw: you don't need to prefix css3 transforms with jQuery 1.7+

Update

You can wrap this in a jQuery-plugin to make your life a bit easier:

$.fn.animateRotate = function(angle, duration, easing, complete) {
  return this.each(function() {
    var $elem = $(this);

    $({deg: 0}).animate({deg: angle}, {
      duration: duration,
      easing: easing,
      step: function(now) {
        $elem.css({
           transform: 'rotate(' + now + 'deg)'
         });
      },
      complete: complete || $.noop
    });
  });
};

$('#MyDiv2').animateRotate(90);

http://jsbin.com/ofagog/2/edit

Update2

I optimized it a bit to make the order of easing, duration and complete insignificant.

$.fn.animateRotate = function(angle, duration, easing, complete) {
  var args = $.speed(duration, easing, complete);
  var step = args.step;
  return this.each(function(i, e) {
    args.complete = $.proxy(args.complete, e);
    args.step = function(now) {
      $.style(e, 'transform', 'rotate(' + now + 'deg)');
      if (step) return step.apply(e, arguments);
    };

    $({deg: 0}).animate({deg: angle}, args);
  });
};

Update 2.1

Thanks to matteo who noted an issue with the this-context in the complete-callback. If fixed it by binding the callback with jQuery.proxy on each node.

I've added the edition to the code before from Update 2.

Update 2.2

This is a possible modification if you want to do something like toggle the rotation back and forth. I simply added a start parameter to the function and replaced this line:

$({deg: start}).animate({deg: angle}, args);

If anyone knows how to make this more generic for all use cases, whether or not they want to set a start degree, please make the appropriate edit.

The Usage^{...is quite simple!}

Mainly you've two ways to reach the desired result. But at the first, let's take a look on the arguments:

jQuery.fn.animateRotate(angle, duration, easing, complete)

Except of "angle" are all of them optional and fallback to the default jQuery.fn.animate-properties:

duration: 400
easing: "swing"
complete: function () {}

1st

This way is the short one, but looks a bit unclear the more arguments we pass in.

$(node).animateRotate(90);
$(node).animateRotate(90, function () {});
$(node).animateRotate(90, 1337, 'linear', function () {});

2nd

I prefer to use objects if there are more than three arguments, so this syntax is my favorit:

$(node).animateRotate(90, {
  duration: 1337,
  easing: 'linear',
  complete: function () {},
  step: function () {}
});

when curl is used to download a large file then CURLOPT_TIMEOUT is the main option you have to set for.

CURLOPT_RETURNTRANSFER has to be true in case you are getting file like pdf/csv/image etc.

You may find the further detail over here(correct url) Curl Doc

From that page:

curl_setopt($request, CURLOPT_TIMEOUT, 300); //set timeout to 5 mins

curl_setopt($request, CURLOPT_RETURNTRANSFER, true); // true to get the output as string otherwise false

I'm not gonna claim that this is more elegant than the highest-voted solution...but this is cool (well, at least in my mind LOL) in its own way:

$server = "ftp.lolcats.com"
$filelist = "file1.txt file2.txt"   

"open $server
user $user $password
binary  
cd $dir     
" +
($filelist.split(' ') | %{ "put ""$_""`n" }) | ftp -i -in

As you can see, it uses that dinky built-in windows FTP client. Much shorter and straightforward, too. Yes, I've actually used this and it works!

This Plugin Made by me may be helpful.

Plugin

You can use this plugin you have to supply the key Codes and function to be run like this

simulatorControl([17,83], function(){
 console.log('You have pressed Ctrl+Z');
});

In the code i have displayed how to perform for Ctrl+S. You will get Detailed Documentation On the link. Plugin is in JavaScript Code section Of my Pen on Codepen.

By default, package-lock.json is updated whenever you run npm install. However, this can be disabled globally by setting package-lock=false in ~/.npmrc.

When the global package-lock=false setting is active, you can still force a project’s package-lock.json file to be updated by running:

npm install --package-lock

This command is the only surefire way of forcing a package-lock.json update.

None of the existing answers worked for me with a single-line 10GB file. Grep runs out of memory even on a machine with 768 GB of RAM!

$ cat /proc/meminfo | grep MemTotal
MemTotal:       791236260 kB
$ ls -lh test.json
-rw-r--r-- 1 me all 9.2G Nov 18 15:54 test.json
$ grep -o '0,0,0,0,0,0,0,0,' test.json  | wc -l
grep: memory exhausted
0

So I wrote a very simple Rust program to do it.

1. Install Rust.
2. cargo install count_occurences

$ count_occurences '0,0,0,0,0,0,0,0,' test.json
99094198

It's a little slow (1 minute for 10GB), but at least it doesn't run out of memory!

You can try this way:

$datetime = new DateTime('2010-12-30 23:21:46');

echo $datetime->format(DATE_ATOM);

I used this for the same purpose and it worked:

  select * from INFORMATION_SCHEMA.COLUMNS
  where TABLE_CATALOG= 'theDatabase'
  and COLUMN_NAME like 'theCol%'

The tabularx package gives you

1. the total width as a first parameter, and
2. a new column type X, all X columns will grow to fill up the total width.

For your example:

\usepackage{tabularx}
% ...    
\begin{document}
% ...

\begin{tabularx}{\textwidth}{|X|X|X|}
\hline
Input & Output& Action return \\
\hline
\hline
DNF &  simulation & jsp\\
\hline
\end{tabularx}

So this question has been answered but to me the code used is not simple enough or complete. To me this bit here is what I was looking for and possibly some other people will like this as well.

string dateString = "198101";

if (DateTime.TryParse(dateString, out DateTime Temp) == true)
{
     //do stuff
}

The output is stored in Temp and not needed afterwards, datestring is the input string to be tested.

A simple solution would be doing something like this:

mysqldump -u myuser --no-create-info --extended-insert=FALSE databasename | grep -i "<search string>"

Let's make it simple as hell. If you want a single number for the number of dimensions like 2, 3, 4, etc., then just use tf.rank(). But, if you want the exact shape of the tensor then use tensor.get_shape()

with tf.Session() as sess:
   arr = tf.random_normal(shape=(10, 32, 32, 128))
   a = tf.random_gamma(shape=(3, 3, 1), alpha=0.1)
   print(sess.run([tf.rank(arr), tf.rank(a)]))
   print(arr.get_shape(), ", ", a.get_shape())     


# for tf.rank()    
[4, 3]

# for tf.get_shape()
Output: (10, 32, 32, 128) , (3, 3, 1)

Your code works for me

$date = '15-12-2016';
$nameOfDay = date('D', strtotime($date));
echo $nameOfDay;

Use l instead of D, if you prefer the full textual representation of the name

To find the difference, you need to get the current date and the date in the future. In the following case, I used 2 days for an example of the future date. Calculated by:

2 days * 24 hours * 60 minutes * 60 seconds. We expect the number of seconds in 2 days to be 172,800.

// Set the current and future date
let now = Date()
let nowPlus2Days = Date(timeInterval: 2*24*60*60, since: now)

// Get the number of seconds between these two dates
let secondsInterval = DateInterval(start: now, end: nowPlus2Days).duration

print(secondsInterval) // 172800.0

If the to-be-updated component is not inside the same NamingContainer component (ui:repeat, h:form, h:dataTable, etc), then you need to specify the "absolute" client ID. Prefix with : (the default NamingContainer separator character) to start from root.

<p:ajax process="@this" update="count :subTotal"/>

To be sure, check the client ID of the subTotal component in the generated HTML for the actual value. If it's inside for example a h:form as well, then it's prefixed with its client ID as well and you would need to fix it accordingly.

<p:ajax process="@this" update="count :formId:subTotal"/>

Space separation of IDs is more recommended as <f:ajax> doesn't support comma separation and starters would otherwise get confused.

For vi Editor, use :insert. This will keep all your formatting and not insert auto-indenting.Once done press escape to view the actual formatted file otherwise you'l see some garbage characters. like ^I e.g:

public static void main(String[] args) {
^I
^I System.out.println("Some Garbage printed upon using :insert"); 
}

If you use a CompletableFuture (introduced in Java 8) or a SettableFuture (from Google Guava), you can make your test finish as soon as it's done, rather than waiting a pre-set amount of time. Your test would look something like this:

CompletableFuture<String> future = new CompletableFuture<>();
executorService.submit(new Runnable() {         
    @Override
    public void run() {
        future.complete("Hello World!");                
    }
});
assertEquals("Hello World!", future.get());

I agree with the use of instanceof already mentioned.

An additional benefit of using instanceof is that when used with a null reference instanceof of will return false, while a.getClass() would throw a NullPointerException.

The best way

The best way is to insert an appropriate input tag:

<input type="submit" value="submit" />

The best JS way

<form id="form-id">
  <button id="your-id">submit</button>
</form>

var form = document.getElementById("form-id");

document.getElementById("your-id").addEventListener("click", function () {
  form.submit();
});

Enclose the latter JavaScript code by an DOMContentLoaded event (choose only load for backward compatiblity) if you haven't already done so:

window.addEventListener("DOMContentLoaded", function () {
  var form = document.... // copy the last code block!
});

The easy, not recommandable way (the former answer)

Add an onclick attribute to the link and an id to the form:

<form id="form-id">

  <a href="#" onclick="document.getElementById('form-id').submit();"> submit </a>

</form>

All ways

Whatever way you choose, you have call formObject.submit() eventually (where formObject is the DOM object of the <form> tag).

You also have to bind such an event handler, which calls formObject.submit(), so it gets called when the user clicked a specific link or button. There are two ways:

• Recommended: Bind an event listener to the DOM object.

  // 1. Acquire a reference to our <form>.
  //    This can also be done by setting <form name="blub">:
  //       var form = document.forms.blub;
  
  var form = document.getElementById("form-id");
  
  
  // 2. Get a reference to our preferred element (link/button, see below) and
  //    add an event listener for the "click" event.
  document.getElementById("your-id").addEventListener("click", function () {
    form.submit();
  });
  

• Not recommended: Insert inline JavaScript. There are several reasons why this technique is not recommendable. One major argument is that you mix markup (HTML) with scripts (JS). The code becomes unorganized and rather unmaintainable.

  <a href="#" onclick="document.getElementById('form-id').submit();">submit</a>
  
  <button onclick="document.getElementById('form-id').submit();">submit</button>
  

Now, we come to the point at which you have to decide for the UI element which triggers the submit() call.

1. A button

   <button>submit</button>
   

2. A link

   <a href="#">submit</a>
   

Apply the aforementioned techniques in order to add an event listener.

I like @Thomas's answer, and I do some modifications.

features:

• add color
• and input parameter: to let the user choose command (from git config --get-regexp ^.)
• add filter

# .gitconfig

[alias]
    show-cmd = "!f() { \
        sep="?" ;\
        name=${1:-alias};\
        echo -n -e '\\033[48;2;255;255;01m' ;\
        echo -n -e '\\033[38;2;255;0;01m' ;\
        echo "$name"; \
        echo -n -e '\\033[m' ;\
        git config --get-regexp ^$name\\..*$2+ | \
        cut -c 1-40 | \
        sed -e s/^$name.// \
        -e s/\\ /\\ $(printf $sep)--\\>\\ / | \
        column -t -s $(printf $sep) | \
        sort -k 1 ;\
    }; f"

USAGE

1. git show-cmd list alias
2. git show-cmd "" st list alias, and it should contain the string st
3. git show-cmd i18n show i18n setting
4. git show-cmd core editor show core setting, and it should contain editor

DEMO

It's working fine on windows too

Explanation

• you can write the long script on .gitconfig use the syntax as below:

  [alias]
      your-cmd = "!f() { \
          \
      }; f"
  

• name=${1:-alias} same as name = $1 if $1 else -alias

• echo -n -e (see more echo)

  • -n = Do not output a trailing newline.
  • -e Enable interpretation of the following backslash-escaped

• '\\033[38;2;255;0;01m' (see more SGR parameters)

  • \\033[48; : 48 means background color.
  • \\033[38;2;255;0;0m : 38 means fore color. 255;0;0 = Red

• cut -c 1-40 To avoid your command is too long, so take 40 char only.

• sed -e 's/be_replace_string/new_string/' replace string to new string. (if you want to put the special-char(such as space, > ...) should add \\ as the prefix.

• column -t -s $(printf $sep) formats all lines into an evenly spaced column table.

• sort -k 1 sorts all lines based on the value in the first column

I create color.xml file, for naming my color name (black, white...)

 <?xml version="1.0" encoding="utf-8"?>
 <resources>
    <color name="white">#ffffff</color>
    <color name="black">#000000</color>
 </resources>

And in your EditText, set color

<EditText
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="asdsadasdasd"
        android:textColor="@color/black"
        android:background="@color/white"
        />

or use style in you style.xml:

<style name="EditTextStyleWhite" parent="android:style/Widget.EditText">
    <item name="android:textColor">@color/black</item>
    <item name="android:background">@color/white</item>
</style>

and add ctreated style to EditText:

 <EditText
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="asdsadasdasd"
        style="@style/EditTextStyleWhite"
        />

pgcrypto Extension

As of Postgres 9.4, the pgcrypto module includes the gen_random_uuid() function. This function generates one of the random-number based Version 4 type of UUID.

Get contrib modules, if not already available.

sudo apt-get install postgresql-contrib-9.4

Use pgcrypto module.

CREATE EXTENSION "pgcrypto";

The gen_random_uuid() function should now available;

Example usage.

INSERT INTO items VALUES( gen_random_uuid(), 54.321, 31, 'desc 1', 31.94 ) ;

Quote from Postgres doc on uuid-ossp module.

Note: If you only need randomly-generated (version 4) UUIDs, consider using the gen_random_uuid() function from the pgcrypto module instead.

If every char in the file is properly encoded in UTF-8, you won't have any problem reading it using a reader with the UTF-8 encoding. Up to you to check every char of the file and see if you consider it printable or not.

I'm using the following code in xml

android:adjustViewBounds="true"
android:scaleType="centerInside"

After trying the above suggestions, the only thing that worked for me was changing the border attribute to "0" in the following sections of a child theme's style.css (do a "Find" operation to locate each one -- the following are just snippets):

.comment-content table {
    border-bottom: 1px solid #ddd;

.comment-content td {
    border-top: 1px solid #ddd;
    padding: 6px 10px 6px 0;
}

Thus looking like this afterwards:

.comment-content table {
    border-bottom: 0;

.comment-content td {
    border-top: 0;
    padding: 6px 10px 6px 0;
}

You could sort the array first (Ascending by default) and then apply np.flip() (https://docs.scipy.org/doc/numpy/reference/generated/numpy.flip.html)

FYI It works with datetime objects as well.

Example:

    x = np.array([2,3,1,0]) 
    x_sort_asc=np.sort(x) 
    print(x_sort_asc)

    >>> array([0, 1, 2, 3])

    x_sort_desc=np.flip(x_sort_asc) 
    print(x_sort_desc)

    >>> array([3,2,1,0])

Create a class that inherits from IActionFilter.

public class NoCacheAttribute : ActionFilterAttribute
{  
    public override void OnResultExecuting(ResultExecutingContext filterContext)
    {
        filterContext.HttpContext.Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1));
        filterContext.HttpContext.Response.Cache.SetValidUntilExpires(false);
        filterContext.HttpContext.Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
        filterContext.HttpContext.Response.Cache.SetCacheability(HttpCacheability.NoCache);
        filterContext.HttpContext.Response.Cache.SetNoStore();

        base.OnResultExecuting(filterContext);
    }
}

Then put attributes where needed...

[NoCache]
[HandleError]
public class AccountController : Controller
{
    [NoCache]
    [Authorize]
    public ActionResult ChangePassword()
    {
        return View();
    }
}

You can see this example.

// Is this element visible onscreen?
var visible = $(#element).visible( detectPartial );

detectPartial :

• True : the entire element is visible
• false : part of the element is visible

visible is boolean variable which indicates if the element is visible or not.

The code is very long so I can't paste all the code.

There could be any number of reasons why your code doesn't work. Maybe you declared the button variables twice so you aren't actually changing enabling/disabling the button like you think you are. Maybe you are blocking the EDT.

You need to create a SSCCE to post on the forum.

So its up to you to isolate the problem. Start with a simple frame thas two buttons and see if your code works. Once you get that working, then try starting a Thread that simply sleeps for 10 seconds to see if it still works.

Learn how the basice work first before writing a 200 line program.

Learn how to do some basic debugging, we are not mind readers. We can't guess what silly mistake you are doing based on your verbal description of the problem.

Just a thought:

public static string Right(this string @this, int length) {
    return @this.Substring(Math.Max(@this.Length - length, 0));
}

try keyup instead of change.

<script type="text/javascript">
   $(document).ready(function () {
       $('#inputDatabaseName').keyup(function () { alert('test'); });
   });
</script>

Here's the official jQuery documentation for .keyup().

Try with:

myprogram &>/dev/null

to get no output

A convenient way would be boost's string algorithms library.

#include <boost/algorithm/string/classification.hpp> // Include boost::for is_any_of
#include <boost/algorithm/string/split.hpp> // Include for boost::split
// ...

std::vector<std::string> words;
std::string s;
boost::split(words, s, boost::is_any_of(", "), boost::token_compress_on);

You won't be able to do this easily with plain javascript. When you post a form, the form inputs are sent to the server and your page is refreshed - the data is handled on the server side. That is, the submit() function doesn't actually return anything, it just sends the form data to the server.

If you really wanted to get the response in Javascript (without the page refreshing), then you'll need to use AJAX, and when you start talking about using AJAX, you'll need to use a library. jQuery is by far the most popular, and my personal favourite. There's a great plugin for jQuery called Form which will do exactly what it sounds like you want.

Here's how you'd use jQuery and that plugin:

$('#myForm')
    .ajaxForm({
        url : 'myscript.php', // or whatever
        dataType : 'json',
        success : function (response) {
            alert("The server says: " + response);
        }
    })
;

The first thing you should do with date variables is confirm that R reads it as a Date. To do this, for the variable (i.e. vector/column) called Date, in the data frame called EPL2011_12, input

class(EPL2011_12$Date)

The output should read [1] "Date". If it doesn't, you should format it as a date by inputting

EPL2011_12$Date <- as.Date(EPL2011_12$Date, "%d-%m-%y")

Note that the hyphens in the date format ("%d-%m-%y") above can also be slashes ("%d/%m/%y"). Confirm that R sees it as a Date. If it doesn't, try a different formatting command

EPL2011_12$Date <- format(EPL2011_12$Date, format="%d/%m/%y")

Once you have it in Date format, you can use the subset command, or you can use brackets

WhateverYouWant <- EPL2011_12[EPL2011_12$Date > as.Date("2014-12-15"),]

change the name of the image folder to img and then use the HTML code

A char consists of a single character and should be specified in single quotes. It can contain an alphabetic, numerical or even special character. below are a few examples:

char a = '4';
char b = '$';
char c = 'B';

A String defines a line can be used which is specified in double quotes. Below are a few examples:

String a = "Hello World";
String b = "1234";
String c = "%%";

Like the others said, ISO C++ doesn't support that. But you can workaround it. Just use std::vector instead.

int* a = new int[N];
// fill a

class C {
  const std::vector<int> v;
public:
  C():v(a, a+N) {}
};

using System.Globalization;

DateTime d;
DateTime.TryParseExact(
    "2010-08-20T15:00:00",
    "s",
    CultureInfo.InvariantCulture,
    DateTimeStyles.AssumeUniversal, out d);

If you want to load a small number of Private images You can encode the images to base64 and echo them into <img src="{{$image_data}}"> directly:

$path = image.png
$full_path = Storage::path($path);
$base64 = base64_encode(Storage::get($path));
$image_data = 'data:'.mime_content_type($full_path) . ';base64,' . $base64;

I mentioned private because you should only use these methods if you do not want to store images publicly accessible through url ,instead you Must always use the standard way (link storage/public folder and serve images with HTTP server).

Beware encoding to base64() have two important down sides:

1. This will increase image size by ~30%.
2. You combine all of the images sizes in one request, instead of loading them in parallel, this should not be a problem for some small thumbnails but for many images avoid using this method.

If you use python debugger, not only interactive probing of variables but you can get the call stack with the "where" command or "w".

So at the top of your program

import pdb

Then in the code where you want to see what is happening

pdb.set_trace()

and you get dropped into a prompt

To get both upper and lower case merge the two ranges:

$alphas = array_merge(range('A', 'Z'), range('a', 'z'));

In python, you can simply check as follow:

# on your `setUp` definition.
from selenium import webdriver
self.selenium = webdriver.Firefox()

self.assertTrue('your text' in self.selenium.page_source)

Are you using one of the Webpack starter templates for vue (https://github.com/vuejs-templates/webpack)? It already comes set up with vue-loader (https://github.com/vuejs/vue-loader). If you're not using a starter template, you have to set up webpack and vue-loader.

You can then import your scripts to the relevant (single file) components. Before that, you have toexport from your scripts what you want to import to your components.
