worked for me

i had a similiar problem and the gem string-scrub automagically fixed it for me. https://github.com/hsbt/string-scrub If the given string contains an invalid byte sequence then that invalid byte sequence is replaced with the unicode replacement character (?) and a new string is returned.

The error says it all, change:

ViewPager mPager = (ViewPager) findViewById(R.id.fieldspager);

to

final ViewPager mPager = (ViewPager) findViewById(R.id.fieldspager);

Solution using just POST - no $_SESSION

page1.php

<form action="page2.php" method="post">
    <textarea name="textarea1" id="textarea1"></textarea><br />
    <input type="submit" value="submit" />
</form>

page2.php

<?php
    // this page outputs the contents of the textarea if posted
    $textarea1 = ""; // set var to avoid errors
    if(isset($_POST['textarea1'])){
        $textarea1 = $_POST['textarea1']
    }
?>
<textarea><?php echo $textarea1;?></textarea>

Solution using $_SESSION and POST

page1.php

<?php

    session_start(); // needs to be before anything else on page to use $_SESSION
    $textarea1 = "";
    if(isset($_POST['textarea1'])){
        $_SESSION['textarea1'] = $_POST['textarea1'];
    }

?>


<form action="page1.php" method="post">
    <textarea name="textarea1" id="textarea1"></textarea><br />
    <input type="submit" value="submit" />
</form>
<br /><br />
<a href="page2.php">Go to page2</a>

page2.php

<?php
    session_start(); // needs to be before anything else on page to use $_SESSION
    // this page outputs the textarea1 from the session IF it exists
    $textarea1 = ""; // set var to avoid errors
    if(isset($_SESSION['textarea1'])){
        $textarea1 = $_SESSION['textarea1']
    }
?>
<textarea><?php echo $textarea1;?></textarea>

We already have tons of options to get mean by group, adding one more from mosaic package.

mosaic::mean(speed~dive, data = df)
#dive1 dive2 
#0.579 0.440 

This returns a named numeric vector, if needed a dataframe we can wrap it in stack

stack(mosaic::mean(speed~dive, data = df))

#  values   ind
#1  0.579 dive1
#2  0.440 dive2

data

set.seed(123)
df <- data.frame(dive=factor(sample(c("dive1","dive2"),10,replace=TRUE)),
                 speed=runif(10))

$files = array_diff(scandir($dir,SCANDIR_SORT_DESCENDING), array('..', '.'));
print_r($files);

The first four lines of this code will give you reliable YY DD MM YYYY HH Min Sec variables in XP Pro and higher, using WMIC.

@echo off
for /f "tokens=2 delims==" %%a in ('wmic OS Get localdatetime /value') do set "dt=%%a"
set "YY=%dt:~2,2%" & set "YYYY=%dt:~0,4%" & set "MM=%dt:~4,2%" & set "DD=%dt:~6,2%"
set "HH=%dt:~8,2%" & set "Min=%dt:~10,2%" & set "Sec=%dt:~12,2%"

set "datestamp=%YYYY%%MM%%DD%" & set "timestamp=%HH%%Min%%Sec%"
set "fullstamp=%YYYY%-%MM%-%DD%_%HH%-%Min%-%Sec%"
echo datestamp: "%datestamp%"
echo timestamp: "%timestamp%"
echo fullstamp: "%fullstamp%"
pause

Output example:

datestamp: "20200828"
timestamp: "085513"
fullstamp: "2020-08-28_08-55-13"

I found this question serval years ago.

recently I tried to "rewrite" the submit method. below is my code

window.onload= function (){
for(var i= 0;i<document.forms.length;i++){
    (function (p){
        var form= document.forms[i];
        var originFn= form.submit;
        form.submit=function (){
            //do something you like
            alert("submitting "+form.id+" using submit method !");
            originFn();
        }
        form.onsubmit= function (){
            alert("submitting "+form.id+" with onsubmit event !");
        }
    })(i);


}

}

<form method="get" action="" id="form1">
<input type="submit" value="??form1" />
<input type="button" name="" id="" value="button????1" onclick="document.forms[0].submit();" /></form>

It did in IE,but failed in other browsers for the same reason as "cletus"

Trying to do more friendly solution of DecimalToString (https://stackoverflow.com/a/34486763/3852139):

private static decimal Trim(this decimal value)
{
    var s = value.ToString(CultureInfo.InvariantCulture);
    return s.Contains(CultureInfo.InvariantCulture.NumberFormat.NumberDecimalSeparator)
        ? Decimal.Parse(s.TrimEnd('0'), CultureInfo.InvariantCulture)
        : value;
}

private static decimal? Trim(this decimal? value)
{
    return value.HasValue ? (decimal?) value.Value.Trim() : null;
}

private static void Main(string[] args)
{
    Console.WriteLine("=>{0}", 1.0000m.Trim());
    Console.WriteLine("=>{0}", 1.000000023000m.Trim());
    Console.WriteLine("=>{0}", ((decimal?) 1.000000023000m).Trim());
    Console.WriteLine("=>{0}", ((decimal?) null).Trim());
}

NOTE: The following tables were taken from some site when I was doing some R&D on the database. So the naming convention is not proper.

For me, the problem was, my parent table had the different character set than that of the one which I was creating.

1. Iterate over the ResultSet
2. Create a new Object for each row, to store the fields you need
3. Add this new object to ArrayList or Hashmap or whatever you fancy
4. Close the ResultSet, Statement and the DB connection

Done

EDIT: now that you have posted code, I have made a few changes to it.

public List resultSetToArrayList(ResultSet rs) throws SQLException{
  ResultSetMetaData md = rs.getMetaData();
  int columns = md.getColumnCount();
  ArrayList list = new ArrayList(50);
  while (rs.next()){
     HashMap row = new HashMap(columns);
     for(int i=1; i<=columns; ++i){           
      row.put(md.getColumnName(i),rs.getObject(i));
     }
      list.add(row);
  }

 return list;
}

I faced similar problem. In my case client must send data periodically. I hope you have same requirement. Then I set SO_TIMEOUT socket.setSoTimeout(1000 * 60 * 5); which is throw java.net.SocketTimeoutException when specified time is expired. Then I can detect dead client easily.

Ok...so first you need to import the image into your project.

1) Select the PictureBox in the Form Design View

2) Open PictureBox Tasks
(it's the little arrow printed to right on the edge of the PictureBox)

3) Click on "Choose image..."

4) Select the second option "Project resource file:"
(this option will create a folder called "Resources" which you can access with Properties.Resources)

5) Click on "Import..." and select your image from your computer
(now a copy of the image will be saved in "Resources" folder created at step 4)

6) Click on "OK"

Now the image is in your project and you can use it with the Properties command. Just type this code when you want to change the picture in the PictureBox:

pictureBox1.Image = Properties.Resources.MyImage;

Note:
MyImage represent the name of the image...
After typing "Properties.Resources.", all imported image files are displayed...

::WARNING::
.selector has been deprecated as of version 1.7, removed as of 1.9

The jQuery object has a selector property I saw when digging in its code yesterday. Don't know if it's defined in the docs are how reliable it is (for future proofing). But it works!

$('*').selector // returns *

Edit: If you were to find the selector inside the event, that information should ideally be part of the event itself and not the element because an element could have multiple click events assigned through various selectors. A solution would be to use a wrapper to around bind(), click() etc. to add events instead of adding it directly.

jQuery.fn.addEvent = function(type, handler) {
    this.bind(type, {'selector': this.selector}, handler);
};

The selector is being passed as an object's property named selector. Access it as event.data.selector.

Let's try it on some markup (http://jsfiddle.net/DFh7z/):

<p class='info'>some text and <a>a link</a></p>?

$('p a').addEvent('click', function(event) {
    alert(event.data.selector); // p a
});

Disclaimer: Remember that just as with live() events, the selector property may be invalid if DOM traversal methods are used.

<div><a>a link</a></div>

The code below will NOT work, as live relies on the selector property which in this case is a.parent() - an invalid selector.

$('a').parent().live(function() { alert('something'); });

Our addEvent method will fire, but you too will see the wrong selector - a.parent().

I'm using this function that find all images in my letter and attaches it to the message.

a = np.array([1,2,3])
b = np.array([4,5,6])
np.array((a,b))

works just as well as

np.array([[1,2,3], [4,5,6]])

Regardless of whether it is a list of lists or a list of 1d arrays, np.array tries to create a 2d array.

But it's also a good idea to understand how np.concatenate and its family of stack functions work. In this context concatenate needs a list of 2d arrays (or any anything that np.array will turn into a 2d array) as inputs.

np.vstack first loops though the inputs making sure they are at least 2d, then does concatenate. Functionally it's the same as expanding the dimensions of the arrays yourself.

np.stack is a new function that joins the arrays on a new dimension. Default behaves just like np.array.

Look at the code for these functions. If written in Python you can learn quite a bit. For vstack:

return _nx.concatenate([atleast_2d(_m) for _m in tup], 0)

The question is old, yet I'd like to extend the topic with another answer.

My point is, the easiest way to achieve it is just to wrap multiple queries with a transaction. The accepted answer INSERT ... ON DUPLICATE KEY UPDATE is a nice hack, but one should be aware of its drawbacks and limitations:

• As being said, if you happen to launch the query with rows whose primary keys don't exist in the table, the query inserts new "half-baked" records. Probably it's not what you want
• If you have a table with a not null field without default value and don't want to touch this field in the query, you'll get "Field 'fieldname' doesn't have a default value" MySQL warning even if you don't insert a single row at all. It will get you into trouble, if you decide to be strict and turn mysql warnings into runtime exceptions in your app.

I made some performance tests for three of suggested variants, including the INSERT ... ON DUPLICATE KEY UPDATE variant, a variant with "case / when / then" clause and a naive approach with transaction. You may get the python code and results here. The overall conclusion is that the variant with case statement turns out to be twice as fast as two other variants, but it's quite hard to write correct and injection-safe code for it, so I personally stick to the simplest approach: using transactions.

Edit: Findings of Dakusan prove that my performance estimations are not quite valid. Please see this answer for another, more elaborate research.

In the first place consider the Small grid, see: http://getbootstrap.com/css/#grid-options. A max container width of 750 px will maybe to small for you (also read: Why does Bootstrap 3 force the container width to certain sizes?)

When using the Small grid use media queries to set the max-container width:

@media (min-width: 768px) { .container { max-width: 750px; } }

Second also read this question: Bootstrap 3 - 940px width grid?, possible duplicate?

12 x 60 = 720px for the columns and 11 x 20 = 220px

there will also a gutter of 20px on both sides of the grid so 220 + 720 + 40 makes 980px

there is 'no' @ColumnWidth

You colums width will be calculated dynamically based on your settings in variables.less. you could set @grid-columns and @grid-gutter-width. The width of a column will be set as a percentage via grid.less in mixins.less:

.calc-grid(@index, @class, @type) when (@type = width) {
  .col-@{class}-@{index} {
    width: percentage((@index / @grid-columns));
  }
}

update Set @grid-gutter-width to 20px;, @container-desktop: 940px;, @container-large-desktop: @container-desktop and recompile bootstrap.

I had the same problem.

I already had a g++ compiler installed thru MinGW (the package mingw32-gcc-g++) but I needed a C compiler so I ran mingw-get-setup.exe where I was able to have it install the mingw32-base package, the one with the C compiler.

Alas! I had this error when I use gcc to compile:

gcc: error: createprocess: no such file or directory

What I did was, still using the MinGW Installation Manager, I removed the C and C++ compiler packages, namely mingw32-base and mingw32-gcc-g++ and ALSO deleted the C:\MinGW directory itself. Then I reran mingw-get-setup.exe, installed mingw32-base, and voila, it worked :)

you may try like this using jquery

 var arr = [1,2,2,3,4,5,5,5,6,7,7,8,9,10,10];
    var uniqueVals = [];
    $.each(arr, function(i, el){
        if($.inArray(el, uniqueVals) === -1) uniqueVals.push(el);
    });

$key is the index for the current array element, and $val is the value of that array element.

The first element has an index of 0. Therefore, to access it, use $arr[0]

To get the first element of the array, use this

$firstFound = false;
foreach($arr as $key=>$val)
{
    if (!$firstFound)
       $first = $val;
    else
       $firstFound = true;
    // do whatever you want here
}

// now ($first) has the value of the first element in the array

ZPL is the correct way to go. In most cases it is correct to use a driver that abstracts to GDI commands; however Zebra label printers are a special case. The best way to print to a Zebra printer is to generate ZPL directly. Note that the actual printer driver for a Zebra printer is a "plain text" printer - there is not a "driver" that could be updated or changed in the sense we think of most printers having drivers. It's just a driver in the absolute minimalist sense.

For some applications you can use Fraction instead of floating-point numbers.

>>> from fractions import Fraction
>>> Fraction(1, 3**54)
Fraction(1, 58149737003040059690390169)

(For other applications, there's decimal, as suggested out by the other responses.)

basename and dirname solutions are more convenient. Those are alternative commands:

FILE_PATH="/opt/datastores/sda2/test.old.img"
echo "$FILE_PATH" | sed "s/.*\///"

This returns test.old.img like basename.

This is salt filename without extension:

echo "$FILE_PATH" | sed -r "s/.+\/(.+)\..+/\1/"

It returns test.old.

And following statement gives the full path like dirname command.

echo "$FILE_PATH" | sed -r "s/(.+)\/.+/\1/"

It returns /opt/datastores/sda2

You could use SET DATEFORMAT, like in this example

declare @dates table (orig varchar(50) ,parsed datetime)

SET DATEFORMAT ydm;

insert into @dates
select '2008-09-01','2008-09-01'

SET DATEFORMAT ymd;
insert into @dates
select '2008-09-01','2008-09-01'

select * from @dates

You would need to specify the dateformat in the code when you parse your XML data

input[type='text'], input[type='password']
{
   // my css
}

That is the correct way to do it. Sadly CSS is not a programming language.

Manifest.MF contains information about the files contained in the JAR file.

Whenever a JAR file is created a default manifest.mf file is created inside META-INF folder and it contains the default entries like this:

Manifest-Version: 1.0
Created-By: 1.7.0_06 (Oracle Corporation)

These are entries as “header:value” pairs. The first one specifies the manifest version and second one specifies the JDK version with which the JAR file is created.

Main-Class header: When a JAR file is used to bundle an application in a package, we need to specify the class serving an entry point of the application. We provide this information using ‘Main-Class’ header of the manifest file,

Main-Class: {fully qualified classname}

The ‘Main-Class’ value here is the class having main method. After specifying this entry we can execute the JAR file to run the application.

Class-Path header: Most of the times we need to access the other JAR files from the classes packaged inside application’s JAR file. This can be done by providing their fully qualified paths in the manifest file using ‘Class-Path’ header,

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

This header can be used to specify the external JAR files on the same local network and not inside the current JAR.

Package version related headers: When the JAR file is used for package versioning the following headers are used as specified by the Java language specification:

Headers in a manifest
Header                  | Definition
-------------------------------------------------------------------
Name                    | The name of the specification.
Specification-Title     | The title of the specification.
Specification-Version   | The version of the specification.
Specification-Vendor    | The vendor of the specification.
Implementation-Title    | The title of the implementation.
Implementation-Version  | The build number of the implementation.
Implementation-Vendor   | The vendor of the implementation.

Package sealing related headers:

We can also specify if any particular packages inside a JAR file should be sealed meaning all the classes defined in that package must be archived in the same JAR file. This can be specified with the help of ‘Sealed’ header,

Name: {package/some-package/} Sealed:true

Here, the package name must end with ‘/’.

Enhancing security with manifest files:

We can use manifest files entries to ensure the security of the web application or applet it packages with the different attributes as ‘Permissions’, ‘Codebae’, ‘Application-Name’, ‘Trusted-Only’ and many more.

META-INF folder:

This folder is where the manifest file resides. Also, it can contain more files containing meta data about the application. For example, in an EJB module JAR file, this folder contains the EJB deployment descriptor for the EJB module along with the manifest file for the JAR. Also, it contains the xml file containing mapping of an abstract EJB references to concrete container resources of the application server on which it will be run.

If you came here searching OpenID Connect (OIDC): OAuth 2.0 != OIDC

I recognize that this is tagged for oauth 2.0 and NOT OIDC, however there is frequently a conflation between the 2 standards since both standards can use JWTs and the aud claim. And one (OIDC) is basically an extension of the other (OAUTH 2.0). (I stumbled across this question looking for OIDC myself.)

OAuth 2.0 Access Tokens##

For OAuth 2.0 Access tokens, existing answers pretty well cover it. Additionally here is one relevant section from OAuth 2.0 Framework (RFC 6749)

For public clients using implicit flows, this specification does not provide any method for the client to determine what client an access token was issued to.
...
Authenticating resource owners to clients is out of scope for this specification. Any specification that uses the authorization process as a form of delegated end-user authentication to the client (e.g., third-party sign-in service) MUST NOT use the implicit flow without additional security mechanisms that would enable the client to determine if the access token was issued for its use (e.g., audience- restricting the access token).

OIDC ID Tokens##

OIDC has ID Tokens in addition to Access tokens. The OIDC spec is explicit on the use of the aud claim in ID Tokens. (openid-connect-core-1.0)

aud
REQUIRED. Audience(s) that this ID Token is intended for. It MUST contain the OAuth 2.0 client_id of the Relying Party as an audience value. It MAY also contain identifiers for other audiences. In the general case, the aud value is an array of case sensitive strings. In the common special case when there is one audience, the aud value MAY be a single case sensitive string.

furthermore OIDC specifies the azp claim that is used in conjunction with aud when aud has more than one value.

azp
OPTIONAL. Authorized party - the party to which the ID Token was issued. If present, it MUST contain the OAuth 2.0 Client ID of this party. This Claim is only needed when the ID Token has a single audience value and that audience is different than the authorized party. It MAY be included even when the authorized party is the same as the sole audience. The azp value is a case sensitive string containing a StringOrURI value.

Although you could easily find a tutorial how to handle file uploads with php, and there are functions (manual) to handle CSVs, I will post some code because just a few days ago I worked on a project, including a bit of code you could use...

HTML:

<table width="600">
<form action="<?php echo $_SERVER["PHP_SELF"]; ?>" method="post" enctype="multipart/form-data">

<tr>
<td width="20%">Select file</td>
<td width="80%"><input type="file" name="file" id="file" /></td>
</tr>

<tr>
<td>Submit</td>
<td><input type="submit" name="submit" /></td>
</tr>

</form>
</table>

PHP:

if ( isset($_POST["submit"]) ) {

   if ( isset($_FILES["file"])) {

            //if there was an error uploading the file
        if ($_FILES["file"]["error"] > 0) {
            echo "Return Code: " . $_FILES["file"]["error"] . "<br />";

        }
        else {
                 //Print file details
             echo "Upload: " . $_FILES["file"]["name"] . "<br />";
             echo "Type: " . $_FILES["file"]["type"] . "<br />";
             echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
             echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";

                 //if file already exists
             if (file_exists("upload/" . $_FILES["file"]["name"])) {
            echo $_FILES["file"]["name"] . " already exists. ";
             }
             else {
                    //Store file in directory "upload" with the name of "uploaded_file.txt"
            $storagename = "uploaded_file.txt";
            move_uploaded_file($_FILES["file"]["tmp_name"], "upload/" . $storagename);
            echo "Stored in: " . "upload/" . $_FILES["file"]["name"] . "<br />";
            }
        }
     } else {
             echo "No file selected <br />";
     }
}

I know there must be an easier way to do this, but I read the CSV file and store the single cells of every record in an two dimensional array.

if ( isset($storagename) && $file = fopen( "upload/" . $storagename , r ) ) {

    echo "File opened.<br />";

    $firstline = fgets ($file, 4096 );
        //Gets the number of fields, in CSV-files the names of the fields are mostly given in the first line
    $num = strlen($firstline) - strlen(str_replace(";", "", $firstline));

        //save the different fields of the firstline in an array called fields
    $fields = array();
    $fields = explode( ";", $firstline, ($num+1) );

    $line = array();
    $i = 0;

        //CSV: one line is one record and the cells/fields are seperated by ";"
        //so $dsatz is an two dimensional array saving the records like this: $dsatz[number of record][number of cell]
    while ( $line[$i] = fgets ($file, 4096) ) {

        $dsatz[$i] = array();
        $dsatz[$i] = explode( ";", $line[$i], ($num+1) );

        $i++;
    }

        echo "<table>";
        echo "<tr>";
    for ( $k = 0; $k != ($num+1); $k++ ) {
        echo "<td>" . $fields[$k] . "</td>";
    }
        echo "</tr>";

    foreach ($dsatz as $key => $number) {
                //new table row for every record
        echo "<tr>";
        foreach ($number as $k => $content) {
                        //new table cell for every field of the record
            echo "<td>" . $content . "</td>";
        }
    }

    echo "</table>";
}

So I hope this will help, it is just a small snippet of code and I have not tested it, because I used it slightly different. The comments should explain everything.

You might find it better to use a 3rd party program to enter the queries into Access such as WinSQL I think from memory WinSQL supports multiple queries via it's batch feature.

I ultimately found it easier to just write a program in perl to do bulk INSERTS into an Access via ODBC. You could use vbscript or any language that supports ODBC though.

You can then do anything you like and have your own complicated logic to handle the importing.

If you join the facilities table twice you will get what you are after:

select u.* 
from room u 
  JOIN facilities_r fu1 on fu1.id_uc = u.id_uc and fu1.id_fu = '4'
  JOIN facilities_r fu2 on fu2.id_uc = u.id_uc and fu2.id_fu = '3' 
where 1 and vizibility='1' 
group by id_uc 
order by u_premium desc, id_uc desc

Tumblr has a public API that provides JSON. You can get a dump of posts using a simple url like http://puppygifs.tumblr.com/api/read/json.

Solution in Kotlin:

val nowInEpoch = Instant.now().epochSecond

Make sure your minimum SDK version is 26.

This option comes in curl 7.73.0:

curl --create-dirs -O --output-dir /tmp/receipes https://example.com/pancakes.jpg

#include <stdio.h>

int main(){
    char name[] =  "derp" "herp";
    printf("\"%s\"\n", name);//"derpherp"
    return 0;
}

You can use a SELECT CASE statement like so:

select case when EXISTS (
 select 1 
 from <table>
 where <condition>
 ) then TRUE else FALSE end

It returns TRUE when your query in the parents exists.

Inside relative path tag do as follows

<relative>{project_name}/pom.xml</relative>

and then RunAs-> Maven build

It worked for me.

I suggest using isoFormat for better appearance on the web pages.

package com.mycompany;

import javax.validation.constraints.Min;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;

public class Car {

    @NotNull
    private String manufacturer;

    @NotNull
    @Size(min = 2, max = 14)
    private String licensePlate;

    @Min(2)
    private int seatCount;

    public Car(String manufacturer, String licencePlate, int seatCount) {
        this.manufacturer = manufacturer;
        this.licensePlate = licencePlate;
        this.seatCount = seatCount;
    }

    //getters and setters ...
}

@NotNull, @Size and @Min are so-called constraint annotations, that we use to declare constraints, which shall be applied to the fields of a Car instance:

manufacturer shall never be null

licensePlate shall never be null and must be between 2 and 14 characters long

seatCount shall be at least 2.

You should read this getopts tutorial.

Example with -a switch that requires an argument :

#!/bin/bash

while getopts ":a:" opt; do
  case $opt in
    a)
      echo "-a was triggered, Parameter: $OPTARG" >&2
      ;;
    \?)
      echo "Invalid option: -$OPTARG" >&2
      exit 1
      ;;
    :)
      echo "Option -$OPTARG requires an argument." >&2
      exit 1
      ;;
  esac
done

Like greybot said(getopt != getopts) :

The external command getopt(1) is never safe to use, unless you know it is GNU getopt, you call it in a GNU-specific way, and you ensure that GETOPT_COMPATIBLE is not in the environment. Use getopts (shell builtin) instead, or simply loop over the positional parameters.

In VS Express 2012 I couldn't find System.Web.Mvc in the "assemblies" tab, but after a bit of searching I found out that I need to look into "assemblies\extensions" tab rather than the default "assemblies\framework" tab.

Thing is an inner class with an automatic connection to an instance of Hello. You get a compile error because there is no instance of Hello for it to attach to. You can fix it most easily by changing it to a static nested class which has no connection:

static class Thing

The MySQL daemon should not be executed as the system user root which (normally) do not has any restrictions.

According to your cli, I suppose you wanted to execute the initscript instead:

sudo /etc/init.d/mysql stop

Another way would be to use the mysqladmin tool (note, root is the MySQL root user here, not the system root user):

/usr/local/mysql/bin/mysqladmin --port=8889 -u root shutdown

1. An Object file is the compiled file itself. There is no difference between the two.

2. An executable file is formed by linking the Object files.

3. Object file contains low level instructions which can be understood by the CPU. That is why it is also called machine code.

4. This low level machine code is the binary representation of the instructions which you can also write directly using assembly language and then process the assembly language code (represented in English) into machine language (represented in Hex) using an assembler.

Here's a typical high level flow for this process for code in High Level Language such as C

--> goes through pre-processor

--> to give optimized code, still in C

--> goes through compiler

--> to give assembly code

--> goes through an assembler

--> to give code in machine language which is stored in OBJECT FILES

--> goes through Linker

--> to get an executable file.

This flow can have some variations for example most compilers can directly generate the machine language code, without going through an assembler. Similarly, they can do the pre-processing for you. Still, it is nice to break up the constituents for a better understanding.

Simply call list on the generator.

lst = list(gen)
lst

Be aware that this affects the generator which will not return any further items.

You also cannot directly call list in IPython, as it conflicts with a command for listing lines of code.

Tested on this file:

def gen():
    yield 1
    yield 2
    yield 3
    yield 4
    yield 5
import ipdb
ipdb.set_trace()

g1 = gen()

text = "aha" + "bebe"

mylst = range(10, 20)

which when run:

$ python code.py 
> /home/javl/sandbox/so/debug/code.py(10)<module>()
      9 
---> 10 g1 = gen()
     11 

ipdb> n
> /home/javl/sandbox/so/debug/code.py(12)<module>()
     11 
---> 12 text = "aha" + "bebe"
     13 

ipdb> lst = list(g1)
ipdb> lst
[1, 2, 3, 4, 5]
ipdb> q
Exiting Debugger.

General method for escaping function/variable/debugger name conflicts

There are debugger commands p and pp that will print and prettyprint any expression following them.

So you could use it as follows:

$ python code.py 
> /home/javl/sandbox/so/debug/code.py(10)<module>()
      9 
---> 10 g1 = gen()
     11 

ipdb> n
> /home/javl/sandbox/so/debug/code.py(12)<module>()
     11 
---> 12 text = "aha" + "bebe"
     13 

ipdb> p list(g1)
[1, 2, 3, 4, 5]
ipdb> c

There is also an exec command, called by prefixing your expression with !, which forces debugger to take your expression as Python one.

ipdb> !list(g1)
[]

For more details see help p, help pp and help exec when in debugger.

ipdb> help exec
(!) statement
Execute the (one-line) statement in the context of
the current stack frame.
The exclamation point can be omitted unless the first word
of the statement resembles a debugger command.
To assign to a global variable you must always prefix the
command with a 'global' command, e.g.:
(Pdb) global list_options; list_options = ['-l']

Even if it is really discouraged to use merge cells in Excel (use Center Across Selection for instance if needed), the cell that "contains" the value is the one on the top left (at least, that's a way to express it).

Hence, you can get the value of merged cells in range B4:B11 in several ways:

• Range("B4").Value
• Range("B4:B11").Cells(1).Value
• Range("B4:B11").Cells(1,1).Value

You can also note that all the other cells have no value in them. While debugging, you can see that the value is empty.

Also note that Range("B4:B11").Value won't work (raises an execution error number 13 if you try to Debug.Print it) because it returns an array.

You can find an introduction to file dialogs in the Java Tutorials. Java2s also has some example code.

It goes through the object as a key-value structure. Then it will add a new property named 'Active' and a sample value for this property ('Active) to every single object inside of this object. this code can be applied for both array of objects and object of objects.

   Object.keys(Results).forEach(function (key){
            Object.defineProperty(Results[key], "Active", { value: "the appropriate value"});
        });

Use char* strncpy(char* dest, char* src, int n) from <cstring>. In your case you will need to use the following code:

char* substr = malloc(4);
strncpy(substr, buff+10, 4);

Full documentation on the strncpy function here.

I tried a certain sequence that seems to work as you can see below:

ThisWorkbook.Saved = True
Application.Quit
Application.ActiveWindow.Close SaveChanges:=False
ActiveWorkbook.Close SaveChanges:=False

Apart from "readability", no. They're functionally equivalent.

_{("Readability" is in quotes because I hate == false and find ! much more readable. But others don't.)}

No, that's not possible. The port is not part of the hostname, so it has no meaning in the hosts-file.

If you put constrains on a generic class or method, every other generic class or method that is using it need to have "at least" those constrains.

According to the latest pandas documentation you can read a csv file selecting only the columns which you want to read.

import pandas as pd

df = pd.read_csv('some_data.csv', usecols = ['col1','col2'], low_memory = True)

Here we use usecols which reads only selected columns in a dataframe.

We are using low_memory so that we Internally process the file in chunks.

If you write this yourself these are some of the points to keep in mind

Proper authentication between the device and the Sync Server

A sync protocol between the device and the server. It will usually go in 3 phases, authentication, data exchange, status exchange (which operations worked and which failed)

Pick your payload format. I suggest SyncML based XML mixed with JSON based format to represent the actual data. So SyncML for the protocol, and JSON for the actual data being exchanged. Using JSON Array while manipulating the data is always preferred as it is easy to access data using JSON Array.

Keeping track of data changes on both client and server. You can maintain a changelog of ids that change and pick them up during a sync session. Also, clear the changelog as the objects are successfully synchronized. You can also use a boolean variable to confirm the synchronization status, i.e. last time of sync. It will be helpful for end users to identify the time when last sync is done.

Need to have a way to communicate from the server to the device to start a sync session as data changes on the server. You can use C2DM or write your own persistent tcp based communication. The tcp approach is a lot seamless

A way to replicate data changes across multiple devices

And last but not the least, a way to detect and handle conflicts

Hope this helps as a good starting point.

Set the items into display: inline and use :after:

.text span { display: inline }
.break-after:after { content: '\A'; white-space:pre; }

and add the class into your html spans:

<span class="medium break-after">We</span>

You could try the somewhat dangerous: taskkill /IM cmd.exe ..dangerous bcz that will kill the cmd that is open and any cmd's opened before it.

Or add a verification to confirm that you had the right cmd.exe and then kill it via PID, such as this:

set loc=%time%%random%
title=%loc%
for /f "tokens=2 delims= " %%A in ('tasklist /v ^| findstr /i "%loc%"') do (taskkill /PID %%A) 

Substitute (pslist &&A) or (tasklist /FI "PID eq %%A") for the (taskkill /PID %%A) if you want to check it first (and maybe have pstools installed).

In my case i was using ref callbacks,

  <input id="usuario" className="form-control" placeholder="Usuario"
                                                       name="usuario" type="usuario"
                                                       onKeyUp={this._validateMail.bind(this)}
                                                       onChange={()=> this._validateMail()}
                                                       ref={(val) =>{ this._username = val}}
                                                    >

To obtain the value. So enzyme will not change the value of this._username.

So i had to:

login.node._username.value = "[email protected]";
    user.simulate('change');
    expect(login.state('mailValid')).toBe(true);

To be able to set the value then call change . And then assert.

The best way is you should destroy the slick slider after reinitializing it.

function slickCarousel() {
  $('.skills_section').slick({
    infinite: true,
    slidesToShow: 3,
    slidesToScroll: 1
  });
}
function destroyCarousel() {
  if ($('.skills_section').hasClass('slick-initialized')) {
    $('.skills_section').slick('destroy');
  }      
}

$.ajax({
  type: 'get',
  url: '/public/index',
  dataType: 'script',
  data: data_send,
  success: function() {
    destroyCarousel()
    slickCarousel();
  }
});

If you really mean exactly what you say (that you only need to find out IF "there are any keys" in B and not in A, not WHICH ONES might those be if any), the fastest way should be:

if any(True for k in dictB if k not in dictA): ...

If you actually need to find out WHICH KEYS, if any, are in B and not in A, and not just "IF" there are such keys, then existing answers are quite appropriate (but I do suggest more precision in future questions if that's indeed what you mean;-).

The fastest way to parse HTML in Chrome and Firefox is Range#createContextualFragment:

var range = document.createRange();
range.selectNode(document.body); // required in Safari
var fragment = range.createContextualFragment('<h1>html...</h1>');
var firstNode = fragment.firstChild;

I would recommend to create a helper function which uses createContextualFragment if available and falls back to innerHTML otherwise.

Benchmark: http://jsperf.com/domparser-vs-createelement-innerhtml/3

Using ES6 string literals, would be much shorter:

const insertAt = (str, sub, pos) => `${str.slice(0, pos)}${sub}${str.slice(pos)}`;_x000D_
    _x000D_
console.log(insertAt('I want apple', ' an', 6)) // logs 'I want an apple'

Linting is the process of running a program that will analyse code for potential errors.

See lint on wikipedia:

lint was the name originally given to a particular program that flagged some suspicious and non-portable constructs (likely to be bugs) in C language source code. The term is now applied generically to tools that flag suspicious usage in software written in any computer language.

Use position: fixed, and anchor it to the top and right sides of the page:

#fixed-div {
    position: fixed;
    top: 1em;
    right: 1em;
}

IE6 does not support position: fixed, however. If you need this functionality in IE6, this purely-CSS solution seems to do the trick. You'll need a wrapper <div> to contain some of the styles for it to work, as seen in the stylesheet.

Given that the HTML datalist tag is still not fully supported, an alternate approach that I used is the Dojo Toolkit ComboBox. It was easier to implement and better documented than other options I've explored. It also plays nicely with existing frameworks. In my case, I added this combobox to an existing website that's based on Codeigniter and Bootstrap with no problems You just need to be sure to apply the Dojo theme (e.g. class="claro") to the combo's parent element instead of the body tag to avoid styling conflicts.

First, include the CSS for one of the Dojo themes (such as 'Claro'). It's important that the CSS file is included prior to the JS files below.

<link rel="stylesheet" href="https://ajax.googleapis.com/ajax/libs/dojo/1.9.6/dijit/themes/claro/claro.css" />

Next, include jQuery and Dojo Toolkit via CDN

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/dojo/1.10.3/dojo/dojo.js"></script>

Next, you can just follow Dojo's sample code or use the sample below to get a working combobox.

<body>
    <!-- Dojo Dijit ComboBox with 'Claro' theme -->
    <div class="claro"><input id="item_name_1" class=""/></div>

    <script type="text/javascript">
        $(document).ready(function () {
            //In this example, dataStore is simply an array of JSON-encoded id/name pairs
            dataStore = [{"id":"43","name":"Domain Name Renewal"},{"id":"42","name":"Hosting Renewal"}];

            require(
                [ "dojo/store/Memory", "dijit/form/ComboBox", "dojo/domReady!"], 
                function (Memory, ComboBox) {
                    var stateStore = new Memory({
                        data: dataStore
                    });

                    var combo = new ComboBox({
                        id: "item_name_1",
                        name: "desc_1",
                        store: stateStore,
                        searchAttr: "name"},                        
                        "item_name_1"
                        ).startup();

                });

        });

    </script>
</body>

for ex.

<input b="demo">

And

(input[@b='demo'])[1]

I use an asp:Button:

<asp:Button runat="server"
            OnClientClick="return location='targetPage', true;"
            UseSubmitBehavior="False"
            Text="Button Text Here"
/>

This way, the operation of the button is completely client-side and the button acts just like a link to the targetPage.

plt.imshow displays the image on the axes, but if you need to display multiple images you use show() to finish the figure. The next example shows two figures:

import numpy as np
from keras.datasets import mnist
(X_train,y_train),(X_test,y_test) = mnist.load_data()
from matplotlib import pyplot as plt
plt.imshow(X_train[0])
plt.show()
plt.imshow(X_train[1])
plt.show()

In Google Colab, if you comment out the show() method from previous example just a single image will display (the later one connected with X_train[1]).

Here is the content from the help:

plt.show(*args, **kw)
        Display a figure.
        When running in ipython with its pylab mode, display all
        figures and return to the ipython prompt.

        In non-interactive mode, display all figures and block until
        the figures have been closed; in interactive mode it has no
        effect unless figures were created prior to a change from
        non-interactive to interactive mode (not recommended).  In
        that case it displays the figures but does not block.

        A single experimental keyword argument, *block*, may be
        set to True or False to override the blocking behavior
        described above.



plt.imshow(X, cmap=None, norm=None, aspect=None, interpolation=None, alpha=None, vmin=None, vmax=None, origin=None, extent=None, shape=None, filternorm=1, filterrad=4.0, imlim=None, resample=None, url=None, hold=None, data=None, **kwargs)
        Display an image on the axes.

Parameters
----------
X : array_like, shape (n, m) or (n, m, 3) or (n, m, 4)
    Display the image in `X` to current axes.  `X` may be an
    array or a PIL image. If `X` is an array, it
    can have the following shapes and types:

    - MxN -- values to be mapped (float or int)
    - MxNx3 -- RGB (float or uint8)
    - MxNx4 -- RGBA (float or uint8)

    The value for each component of MxNx3 and MxNx4 float arrays
    should be in the range 0.0 to 1.0. MxN arrays are mapped
    to colors based on the `norm` (mapping scalar to scalar)
    and the `cmap` (mapping the normed scalar to a color).

When using spark.read.csv, I find that using the options escape='"' and multiLine=True provide the most consistent solution to the CSV standard, and in my experience works the best with CSV files exported from Google Sheets.

That is,

#set inferSchema=False to read everything as string
df = spark.read.csv("myData.csv", escape='"', multiLine=True,
     inferSchema=False, header=True)

An explanation of the following error:

org.postgresql.util.PSQLException: FATAL: sorry, too many clients already.

Summary:

You opened up more than the allowed limit of connections to the database. You ran something like this: Connection conn = myconn.Open(); inside of a loop, and forgot to run conn.close();. Just because your class is destroyed and garbage collected does not release the connection to the database. The quickest fix to this is to make sure you have the following code with whatever class that creates a connection:

protected void finalize() throws Throwable  
{  
    try { your_connection.close(); } 
    catch (SQLException e) { 
        e.printStackTrace();
    }
    super.finalize();  
}  

Place that code in any class where you create a Connection. Then when your class is garbage collected, your connection will be released.

Run this SQL to see postgresql max connections allowed:

show max_connections;

The default is 100. PostgreSQL on good hardware can support a few hundred connections at a time. If you want to have thousands, you should consider using connection pooling software to reduce the connection overhead.

Take a look at exactly who/what/when/where is holding open your connections:

SELECT * FROM pg_stat_activity;

The number of connections currently used is:

SELECT COUNT(*) from pg_stat_activity;

Debugging strategy

1. You could give different usernames/passwords to the programs that might not be releasing the connections to find out which one it is, and then look in pg_stat_activity to find out which one is not cleaning up after itself.

2. Do a full exception stack trace when the connections could not be created and follow the code back up to where you create a new Connection, make sure every code line where you create a connection ends with a connection.close();

How to set the max_connections higher:

max_connections in the postgresql.conf sets the maximum number of concurrent connections to the database server.

1. First find your postgresql.conf file
2. If you don't know where it is, query the database with the sql: SHOW config_file;
3. Mine is in: /var/lib/pgsql/data/postgresql.conf
4. Login as root and edit that file.
5. Search for the string: "max_connections".
6. You'll see a line that says max_connections=100.
7. Set that number bigger, check the limit for your postgresql version.
8. Restart the postgresql database for the changes to take effect.

What's the maximum max_connections?

Use this query:

select min_val, max_val from pg_settings where name='max_connections';

I get the value 8388607, in theory that's the most you are allowed to have, but then a runaway process can eat up thousands of connections, and surprise, your database is unresponsive until reboot. If you had a sensible max_connections like 100. The offending program would be denied a new connection.

Assuming you're currently on the branch you want to rename:

git branch -m newname

This is documented in the manual for git-branch, which you can view using

man git-branch

or

git help branch

Specifically, the command is

git branch (-m | -M) [<oldbranch>] <newbranch>

where the parameters are:

   <oldbranch>
       The name of an existing branch to rename.

   <newbranch>
       The new name for an existing branch. The same restrictions as for <branchname> apply.

<oldbranch> is optional, if you want to rename the current branch.

GetUserId() is an extension method on IIdentity and it is in Microsoft.AspNet.Identity.IdentityExtensions. Make sure you have added the namespace with using Microsoft.AspNet.Identity;.

Use a semicolon

OpenFileDialog of = new OpenFileDialog();
of.Filter = "Excel Files|*.xls;*.xlsx;*.xlsm";

There may be two approaches depending on your server side logic.

Approach 1: When server is not smart enough to handle object states.

You could send all cached record unique id’s to server, for example ["id1","id2","id3","id4","id5","id6","id7","id8","id9","id10"] and a boolean parameter to know whether you are requesting new records(pull to refresh) or old records(load more).

Your sever should responsible to return new records(load more records or new records via pull to refresh) as well as id’s of deleted records from ["id1","id2","id3","id4","id5","id6","id7","id8","id9","id10"].

Example:- If you are requesting load more then your request should look something like this:-

{
        "isRefresh" : false,
        "cached" : ["id1","id2","id3","id4","id5","id6","id7","id8","id9","id10"]
}

Now suppose you are requesting old records(load more) and suppose "id2" record is updated by someone and "id5" and "id8" records is deleted from server then your server response should look something like this:-

{
        "records" : [
{"id" :"id2","more_key":"updated_value"},
{"id" :"id11","more_key":"more_value"},
{"id" :"id12","more_key":"more_value"},
{"id" :"id13","more_key":"more_value"},
{"id" :"id14","more_key":"more_value"},
{"id" :"id15","more_key":"more_value"},
{"id" :"id16","more_key":"more_value"},
{"id" :"id17","more_key":"more_value"},
{"id" :"id18","more_key":"more_value"},
{"id" :"id19","more_key":"more_value"},
{"id" :"id20","more_key":"more_value"}],
        "deleted" : ["id5","id8"]
}

But in this case if you’ve a lot of local cached records suppose 500, then your request string will be too long like this:-

{
        "isRefresh" : false,
        "cached" : ["id1","id2","id3","id4","id5","id6","id7","id8","id9","id10",………,"id500"]//Too long request
}

Approach 2: When server is smart enough to handle object states according to date.

You could send the id of first record and the last record and previous request epoch time. In this way your request is always small even if you’ve a big amount of cached records

Example:- If you are requesting load more then your request should look something like this:-

{
        "isRefresh" : false,
        "firstId" : "id1",
        "lastId" : "id10",
        "last_request_time" : 1421748005
}

Your server is responsible to return the id’s of deleted records which is deleted after the last_request_time as well as return the updated record after last_request_time between "id1" and "id10" .

{
        "records" : [
{"id" :"id2","more_key":"updated_value"},
{"id" :"id11","more_key":"more_value"},
{"id" :"id12","more_key":"more_value"},
{"id" :"id13","more_key":"more_value"},
{"id" :"id14","more_key":"more_value"},
{"id" :"id15","more_key":"more_value"},
{"id" :"id16","more_key":"more_value"},
{"id" :"id17","more_key":"more_value"},
{"id" :"id18","more_key":"more_value"},
{"id" :"id19","more_key":"more_value"},
{"id" :"id20","more_key":"more_value"}],
        "deleted" : ["id5","id8"]
}

Pull To Refresh:-

Load More

Got the error (in the function init) with the following code ;

"use strict" ;

var hdr ;

function init(){ // called on load
    hdr = document.getElementById("hdr");
}

... while using the stock browser on a Samsung galaxy Fame ( crap phone which makes it a good tester ) - userAgent ; Mozilla/5.0 (Linux; U; Android 4.1.2; en-gb; GT-S6810P Build/JZO54K) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30

The same code works everywhere else I tried including the stock browser on an older HTC phone - userAgent ; Mozilla/5.0 (Linux; U; Android 2.3.5; en-gb; HTC_WildfireS_A510e Build/GRJ90) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1

The fix for this was to change

var hdr ;

to

var hdr = null ;

Matt's answer is fine, but just to avoid this to propagate to other elements inside the navbar (like when you also have a dropdown), use

.navbar-nav > li > a {
   line-height: 50px;
}

the above all look good

but do you want to keep the result?

if so...

you can use the following

result = [element for element in data if element[1] == search]

then a simple

len(result)

lets you know if anything was found (and now you can do stuff with the results)

of course this does not handle elements which are length less than one (which you should be checking unless you know they always are greater than length 1, and in that case should you be using a tuple? (tuples are immutable))

if you know all items are a set length you can also do:

any(second == search for _, second in data)

or for len(data[0]) == 4:

any(second == search for _, second, _, _ in data)

...and I would recommend using

for element in data:
   ...

instead of

for i in range(len(data)):
   ...

(for future uses, unless you want to save or use 'i', and just so you know the '0' is not required, you only need use the full syntax if you are starting at a non zero value)

You can use "\\r\\n" also for the new line in powershell. I have used this in servicenow tool.

In my case "\r\n" s not working so i tried "\\r\\n" as "\" this symbol work as escape character in powershell.

That's a very general question. One answer is: "it depends what kind of UUID you wish to generate". But a better one is this: "Well, before I answer, can you tell us why you need to code up your own UUID generation algorithm instead of calling the UUID generation functionality that most modern operating systems provide?"

Doing that is easier and safer, and since you probably don't need to generate your own, why bother coding up an implementation? In that case, the answer becomes use whatever your O/S, programming language or framework provides. For example, in Windows, there is CoCreateGuid or UuidCreate or one of the various wrappers available from the numerous frameworks in use. In Linux there is uuid_generate.

If you, for some reason, absolutely need to generate your own, then at least have the good sense to stay away from generating v1 and v2 UUIDs. It's tricky to get those right. Stick, instead, to v3, v4 or v5 UUIDs.

Update: In a comment, you mention that you are using Python and link to this. Looking through the interface provided, the easiest option for you would be to generate a v4 UUID (that is, one created from random data) by calling uuid.uuid4().

If you have some data that you need to (or can) hash to generate a UUID from, then you can use either v3 (which relies on MD5) or v5 (which relies on SHA1). Generating a v3 or v5 UUID is simple: first pick the UUID type you want to generate (you should probably choose v5) and then pick the appropriate namespace and call the function with the data you want to use to generate the UUID from. For example, if you are hashing a URL you would use NAMESPACE_URL:

uuid.uuid3(uuid.NAMESPACE_URL, 'https://ripple.com')

Please note that this UUID will be different than the v5 UUID for the same URL, which is generated like this:

uuid.uuid5(uuid.NAMESPACE_URL, 'https://ripple.com')

A nice property of v3 and v5 URLs is that they should be interoperable between implementations. In other words, if two different systems are using an implementation that complies with RFC4122, they will (or at least should) both generate the same UUID if all other things are equal (i.e. generating the same version UUID, with the same namespace and the same data). This property can be very helpful in some situations (especially in content-addressible storage scenarios), but perhaps not in your particular case.

Use a CultureInfo like this, from MSDN:

// Creates a CultureInfo for German in Germany.
CultureInfo ci = new CultureInfo("de-DE");

// Displays dt, formatted using the CultureInfo
Console.WriteLine(dt.ToString(ci));

More info on MSDN. Here is a link of all different cultures.

Filter: - A filter as the name suggests is a Java class executed by the servlet container for each incoming HTTP request and for each http response. This way, is possible to manage HTTP incoming requests before them reach the resource, such as a JSP page, a servlet or a simple static page; in the same way is possible to manage HTTP outbound response after resource execution.

Interceptor: - Spring Interceptors are similar to Servlet Filters but they acts in Spring Context so are many powerful to manage HTTP Request and Response but they can implement more sophisticated behavior because can access to all Spring context.

Don't make your code so complicated. It can be done simply as below by using a foreach-like iterator:

$.each(buildings, function (index, value) {
    $('#dropListBuilding').append($('<option/>', { 
        value: value,
        text : value 
    }));
});      

You don't need to call json.getJSONArray() at all, because the JSON you're working with already is an array. So, don't construct an instance of JSONObject; use a JSONArray. This should suffice:

// ...
JSONArray json = new JSONArray(result);
// ...

for(int i=0;i<json.length();i++){                        
    HashMap<String, String> map = new HashMap<String, String>();    
    JSONObject e = json.getJSONObject(i);

    map.put("id",  String.valueOf(i));
    map.put("name", "Earthquake name:" + e.getString("eqid"));
    map.put("magnitude", "Magnitude: " +  e.getString("magnitude"));
    mylist.add(map);            
}

You can't use exactly the same methods as in the tutorial, because the JSON you're dealing with needs to be parsed into a JSONArray at the root, not a JSONObject.

The error code 10060 means it cannot connect to the remote peer. It might be because of the network problem or mostly your setting issues, such as proxy setting.

You could try to connect the same host with other tools(such as ncat) and/or with another PC within your same local network to find out where the problem is occuring.

For proxy issue, there are some material here:

Keep in mind to never run executable file in as root.

If your shell supports a new globbing option (can be enabled by: shopt -s globstar), you can use:

echo **/*foo*

to find any files or folders recursively. This is supported by Bash 4, zsh and similar shells.

Personally I've got this shell function defined:

f() { find . -name "*$1*"; }

^{Note: Above line can be pasted directly to shell or added into your user's ~/.bashrc file.}

Then I can look for any files by typing:

f some_name

Alternatively you can use a fd utility with a simple syntax, e.g. fd pattern.

(4+3)*(4*2) == 56

Note that PHP doesn't really support "nested functions", as in defined only in the scope of the parent function. All functions are defined globally. See the docs.

Headings are normally bold-faced; that has been turned off for this demonstration of size correspondence. MSIE and Opera interpret these sizes the same, but note that Gecko browsers and Chrome interpret Heading 6 as 11 pixels instead of 10 pixels/font size 1, and Heading 3 as 19 pixels instead of 18 pixels/font size 4 (though it's difficult to tell the difference even in a direct comparison and impossible in use). It seems Gecko also limits text to no smaller than 10 pixels.

I found a location were one person had successfully built mysql for python2.6, sharing the link, http://www.technicalbard.com/files/MySQL-python-1.2.2.win32-py2.6.exe

The answer's here are talking about the reflection of the change on the docker-compose.yml file.

But what if I want to incorporate the changes I have done in my code, and I believe that will be only possible by rebuilding the image and that I do with following commands

1. docker container stop

docker stop container-id

2. docker container removal

docker rm container-id

3. docker image removal

docker rmi image-id

4. compose the container again

docker-compose up container-name

The slidingExpiration=true value is basically saying that after every request made, the timer is reset and as long as the user makes a request within the timeout value, he will continue to be authenticated.

This is not correct. The authentication cookie timeout will only be reset if half the time of the timeout has passed.

See for example https://support.microsoft.com/de-ch/kb/910439/en-us or https://itworksonmymachine.wordpress.com/2008/07/17/forms-authentication-timeout-vs-session-timeout/

Unfortunately, you can't change the font size or styling in a drop-down list that is created using data validation.

You can style the text in a combo box, however. Follow the instructions here: Excel Data Validation Combo Box

Check out FPDF (with FPDI):

http://www.fpdf.org/

http://www.setasign.de/products/pdf-php-solutions/fpdi/

These will let you open an pdf and add content to it in PHP. I'm guessing you can also use their functionality to search through the existing content for the values you need.

Another possible library is TCPDF: https://tcpdf.org/

Sometimes you still need to use FirstOrDefault if you have to do different tests. If the Key component of your dictionnary is nullable, you can do this:

thisTag = _tags.FirstOrDefault(t => t.Key.SubString(1,1) == 'a');
if(thisTag.Key != null) { ... }

Using FirstOrDefault, the returned KeyValuePair's key and value will both be null if no match is found.

Swift 3

var myNum = 8.09
myNum.rounded() // result = 8 and leaves myNum unmodified

My solution based on the answer by @Bill the Lizard.

Note that these functions will return the empty string if the input string contains nothing but whitespace.

const std::string StringUtils::WHITESPACE = " \n\r\t";

std::string StringUtils::Trim(const std::string& s)
{
    return TrimRight(TrimLeft(s));
}

std::string StringUtils::TrimLeft(const std::string& s)
{
    size_t startpos = s.find_first_not_of(StringUtils::WHITESPACE);
    return (startpos == std::string::npos) ? "" : s.substr(startpos);
}

std::string StringUtils::TrimRight(const std::string& s)
{
    size_t endpos = s.find_last_not_of(StringUtils::WHITESPACE);
    return (endpos == std::string::npos) ? "" : s.substr(0, endpos+1);
}

If you have several threads executing the methods m1 and m2 in the code below:

class SomeClass {
    private int i = 0;

    public void m1() { i = 5; }
    public int m2() { return i; }
}

you have the guarantee that any thread calling m2 will either read 0 or 5.

On the other hand, with this code (where i is a long):

class SomeClass {
    private long i = 0;

    public void m1() { i = 1234567890L; }
    public long m2() { return i; }
}

a thread calling m2 could read 0, 1234567890L, or some other random value because the statement i = 1234567890L is not guaranteed to be atomic for a long (a JVM could write the first 32 bits and the last 32 bits in two operations and a thread might observe i in between).

With BDD it's

@Test
public void testOrderWithBDD() {


    // Given
    ServiceClassA firstMock = mock(ServiceClassA.class);
    ServiceClassB secondMock = mock(ServiceClassB.class);

    //create inOrder object passing any mocks that need to be verified in order
    InOrder inOrder = inOrder(firstMock, secondMock);

    willDoNothing().given(firstMock).methodOne();
    willDoNothing().given(secondMock).methodTwo();

    // When
    firstMock.methodOne();
    secondMock.methodTwo();

    // Then
    then(firstMock).should(inOrder).methodOne();
    then(secondMock).should(inOrder).methodTwo();


}

I solved this exception by changing the target sdk version from 19 onwards kitkat version AndroidManifest.xml.

<uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="19" />

Use this code :

if (lowerBound <= val && val < upperBound)
or
if (lowerBound <= val && val <= upperBound)

Depending on what you want to accomplish, you might replace INSERT with INSERT IGNORE in your file. This will avoid generating an error for the rows that you are trying to insert and already exist.

See http://dev.mysql.com/doc/refman/5.5/en/insert.html.

Select's default value should be one of its value in the list. In order to load the select with default value you can use ng-options. A scope variable need to be set in the controller and that variable is assigned as ng-model in HTML's select tag.

You can use splash screen in your first loading Activity like this:

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.splash);

        Thread welcomeThread = new Thread() {

            @Override
            public void run() {
                try {
                    super.run();
                    sleep(10000);  //Delay of 10 seconds
                } catch (Exception e) {

                } finally {

                    Intent i = new Intent(SplashActivity.this,
                            MainActivity.class);
                    startActivity(i);
                    finish();
                }
            }
        };
        welcomeThread.start();
    }

Hope this code helps you.

The space before the = is interpreted as part of the name, and the space after it (as well as the quotation marks) are interpreted as part of the value. So the variable you’ve created can be referenced with %location %. If that’s not what you want, remove the extra space(s) in the definition.

I would do it this way:

(function($) {
jQuery.fn.doSomething = function() {
   return this.each(function() {
      var $this = $(this);

      $this.click(function(event) {
         event.preventDefault();
         // Your function goes here
      });
   });
};
})(jQuery);

Then on document ready you can do stuff like this:

$(document).ready(function() {
   $('#div1').doSomething();
   $('#div2').doSomething();
});

Use the pandas.DataFrame.rename funtion. Check this link for description.

data.rename(columns = {'gdp': 'log(gdp)'}, inplace = True)

If you intend to rename multiple columns then

data.rename(columns = {'gdp': 'log(gdp)', 'cap': 'log(cap)', ..}, inplace = True)

JavaScript does not have such declarations. It would be:

var cubes = ...

regardless

But you can do:

for(var i = 0; i < cubes.length; i++)
{
  for(var j = 0; j < cubes[i].length; j++)
  {

  }
}

Note that JavaScript allows jagged arrays, like:

[
  [1, 2, 3],
  [1, 2, 3, 4]
]

since arrays can contain any type of object, including an array of arbitrary length.

As noted by MDC:

"for..in should not be used to iterate over an Array where index order is important"

If you use your original syntax, there is no guarantee the elements will be visited in numeric order.

There is solution with all necessary details for Windows 7 x64:

Many answers forget to mention that you need to add new version of php_curl.dll file from this location: http://www.anindya.com/php-5-4-3-and-php-5-3-13-x64-64-bit-for-windows/

I added new version of php_curl.dll from archive php_curl-5.4.3-VC9-x64.zip to folders: C:\wamp\bin\php\php5.4.3\ext and C:\Windows\System32 and everything was fine!

To convert a generic list to data table, you could use the DataTableGenerator

This library lets you convert your list into a data table with multi-feature like

• Translate data table header
• specify some column to show

I created this test case: http://jsfiddle.net/ccQnK/1/ , I used the Javascript replace function with regular expressions to get the results that you want.

$(document).ready(function() {
    var myContent = '<div id="test">Hello <span>world!</span></div>';
    alert(myContent.replace(/(<([^>]+)>)/ig,""));
});

I personally prefer

LocalDateTime.now(ZoneOffset.UTC);

as it is the most readable option.

You could use table, i.e.

n_occur <- data.frame(table(vocabulary$id))

gives you a data frame with a list of ids and the number of times they occurred.

n_occur[n_occur$Freq > 1,]

tells you which ids occurred more than once.

returns the records with more than one occurrence.

It's a surprisingly little-known feature of C++ (as evidenced by the fact that no-one has given this as an answer yet), but it actually has special syntax for value-initializing an array:

new int[10]();

Note that you must use the empty parentheses — you cannot, for example, use (0) or anything else (which is why this is only useful for value initialization).

This is explicitly permitted by ISO C++03 5.3.4[expr.new]/15, which says:

A new-expression that creates an object of type T initializes that object as follows:

...

• If the new-initializer is of the form (), the item is value-initialized (8.5);

and does not restrict the types for which this is allowed, whereas the (expression-list) form is explicitly restricted by further rules in the same section such that it does not allow array types.

This is specific for each site. So if you type that once, you will only get through that site and all other sites will need a similar type-through.

It is also remembered for that site and you have to click on the padlock to reset it (so you can type it again):

Needless to say use of this "feature" is a bad idea and is unsafe - hence the name.

You should find out why the site is showing the error and/or stop using it until they fix it. HSTS specifically adds protections for bad certs to prevent you clicking through them. The fact it's needed suggests there is something wrong with the https connection - like the site or your connection to it has been hacked.

The chrome developers also do change this periodically. They changed it recently from badidea to thisisunsafe so everyone using badidea, suddenly stopped being able to use it. You should not depend on it. As Steffen pointed out in the comments below, it is available in the code should it change again though they now base64 encode it to make it more obscure. The last time they changed they put this comment in the commit:

Rotate the interstitial bypass keyword

The security interstitial bypass keyword hasn't changed in two years and awareness of the bypass has been increased in blogs and social media. Rotate the keyword to help prevent misuse.

I think the message from the Chrome team is clear - you should not use it. It would not surprise me if they removed it completely in future.

If you are using this when using a self-signed certificate for local testing then why not just add your self-signed certificate certificate to your computer's certificate store so you get a green padlock and do not have to type this? Note Chrome insists on a SAN field in certificates now so if just using the old subject field then even adding it to the certificate store will not result in a green padlock.

If you leave the certificate untrusted then certain things do not work. Caching for example is completely ignored for untrusted certificates. As is HTTP/2 Push.

HTTPS is here to stay and we need to get used to using it properly - and not bypassing the warnings with a hack that is liable to change and doesn't work the same as a full HTTPS solution.

Bootstrap 3 introduces responsive tables:

<div class="table-responsive">
  <table class="table">
    ...
  </table>
</div>

Bootstrap 4 is similar, but with more control via some new classes:

...responsive across all viewports ... with .table-responsive. Or, pick a maximum breakpoint with which to have a responsive table up to by using .table-responsive{-sm|-md|-lg|-xl}.

In my case it was that the Windows OS version I was on did not support the tag I was trying to pull. Utilizing an older tag allowed me to get this to work.

Specifically:

docker pull mcr.microsoft.com/windows/nanoserver:1903 errored

docker pull mcr.microsoft.com/windows/nanoserver:1803-amd64 worked

Yes, it's a valid test although there's an implicit conversion from int to double. For clarity/simplicity you should use (foo.x == 0.0) to test. That will hinder NAN errors/division by zero, but the double value can in some cases be very very very close to 0, but not exactly zero, and then the test will fail (I'm talking about in general now, not your code). Division by that will give huge numbers.

If this has anything to do with money, do not use float or double, instead use BigDecimal.

Pass float to sleep, like sleep 0.1

In .Net, you cannot assign a null value to an int or any other struct. Instead, use a Nullable<int>, or int? for short:

int? value = 0;

if (value == 0)
{
    value = null;
}

I resolved my problem on ubunto 20.4 by reinstalling php-mysql.

Remove php-mysql:

sudo apt purge php7.2-mysql

Then install php-mysql:

sudo apt install php7.2-mysql

It will add new configurations in php.ini

We managed to solve the error under Windows Server 2012 by:

1. Removing from "Remove Roles and Features Wizard" .NET Framework 4.5 Features/ASP.NET 4.5 and all its dependent features
2. Re-installing the removed features.

It seems the order of installation is the cause.

Also, make sure you have HTTP Activation installed under WCF Services.

If the Exception is being thrown in that try block then at worst case scenario Exception should be catching anything uncaught.

Consider that the first part of the test is throwing the Exception and wrap that in the try block as well.

After adding the column, you can always add the primary key:

ALTER TABLE goods ADD PRIMARY KEY(id)

As to why your script wasn't working, you need to specify PRIMARY KEY, not just the word PRIMARY:

alter table goods add column `id` int(10) unsigned primary KEY AUTO_INCREMENT;

You appear to have no main function, which is supposed to be the entry-point for your program.

Add a limit to the delete query

delete from orders 
where id_users = 1 and id_product = 2

"FirstLine" + "<br/>" "SecondLine"

The idea of your first snippet is right. You probably meant to check iByteCount == -1: whether the file has at least one byte:

if (iByteCount == -1)  
    System.out.println("NO ERRORS!");
else
    System.out.println("SOME ERRORS!");

I'd say yes - because virtually all existing (at least all non-trivial) javascript code would break if a browser's javascript engine were to run it asynchronously.

Add to that the fact that HTML5 already specifies Web Workers (an explicit, standardized API for multi-threading javascript code) introducing multi-threading into the basic Javascript would be mostly pointless.

(Note to others commenters: Even though setTimeout/setInterval, HTTP-request onload events (XHR), and UI events (click, focus, etc.) provide a crude impression of multi-threadedness - they are still all executed along a single timeline - one at a time - so even if we don't know their execution order beforehand, there's no need to worry about external conditions changing during the execution of an event handler, timed function or XHR callback.)

In Python-3.6 I can see the suggestion in the traceback. That's quite helpful. Hence I will say you guys to pay attention to the error you got, most of the time answers are within that problem ;).

And then as suggested by other folks here either using python terminal or using a command like python -c "import nltk; nltk.download('wordnet')" we can install them on the fly. You just need to run that command once and then it will save the data locally in your home directory.

Update, you probably want to use the built-in native Promise.allSettled:

Promise.allSettled([promise]).then(([result]) => {
   //reach here regardless
   // {status: "fulfilled", value: 33}
});

As a fun fact, this answer below was prior art in adding that method to the language :]

Sure, you just need a reflect:

const reflect = p => p.then(v => ({v, status: "fulfilled" }),
                            e => ({e, status: "rejected" }));

reflect(promise).then((v => {
    console.log(v.status);
});

Or with ES5:

function reflect(promise){
    return promise.then(function(v){ return {v:v, status: "fulfilled" }},
                        function(e){ return {e:e, status: "rejected" }});
}


reflect(promise).then(function(v){
    console.log(v.status);
});

Or in your example:

var arr = [ fetch('index.html'), fetch('http://does-not-exist') ]

Promise.all(arr.map(reflect)).then(function(results){
    var success = results.filter(x => x.status === "fulfilled");
});

I have come to this question and the one below several times.

how to call scalar function in sql server 2008

Each time, I try entering the Function using the syntax shown here in SQL Server Management Studio, or SSMS, to see the results, and each time I get the errors.

For me, that is because my result set is in tabular data format. Therefore, to see the results in SSMS, I have to call it like this:

SELECT * FROM dbo.Afisho_rankimin_TABLE(5);

I understand that the author's question involved a scalar function, so this answer is only to help others who come to StackOverflow often when they have a problem with a query (like me).

I hope this helps others.

In API level 11 a new Intent Flag was added just for this: Intent.FLAG_ACTIVITY_CLEAR_TASK

Just to clarify, use this:

Java

intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);

Kotlin

intent.flags = Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TASK

Unfortunately for API lvl <= 10, I haven't yet found a clean solution to this. The "DontHackAndroidLikeThis" solution is indeed pure hackery. You should not do that. :)

Edit: As per @Ben Pearson's comment, for API <=10 now one can use IntentCompat class for the same. One can use IntentCompat.FLAG_ACTIVITY_CLEAR_TASK flag to clear task. So you can support pre API level 11 as well.

I did the below from the Views codebehind to set my property within the view model. Not sure if it really " breaks" the MVVM pattern but its the best and least complexe solution found.

  var data = this.DataContext as DBSelectionViewModel;

        data.PassKey = txtPassKey.Password;

Please see this for more reference of type comparisons in PHP. It should give you a clear understanding.

You can use SimlpeDateFormat to format your date like this:

long unixSeconds = 1372339860;
// convert seconds to milliseconds
Date date = new java.util.Date(unixSeconds*1000L); 
// the format of your date
SimpleDateFormat sdf = new java.text.SimpleDateFormat("yyyy-MM-dd HH:mm:ss z"); 
// give a timezone reference for formatting (see comment at the bottom)
sdf.setTimeZone(java.util.TimeZone.getTimeZone("GMT-4")); 
String formattedDate = sdf.format(date);
System.out.println(formattedDate);

The pattern that SimpleDateFormat takes if very flexible, you can check in the javadocs all the variations you can use to produce different formatting based on the patterns you write given a specific Date. http://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html

• Because a Date provides a getTime() method that returns the milliseconds since EPOC, it is required that you give to SimpleDateFormat a timezone to format the date properly acording to your timezone, otherwise it will use the default timezone of the JVM (which if well configured will anyways be right)

No, you can't, it doesn't support only year, so to do that you need a script, like jQuery or the webshim link you have, which shows year only.

If jQuery would be an option, here is one, borrowed from Sibu:

Javascript

$(function() {
    $( "#datepicker" ).datepicker({dateFormat: 'yy'});
});?

CSS

.ui-datepicker-calendar {
   display: none;
}

Here is an updated fiddle, without the month and prev/next buttons

If bootstrap is an option, check this link, they have a layout how you want.

html

<p id='longText'>Some very very very very very very very very very very very long string</p>

javascript (on doc ready)

var longText = $('#longText');
longText.text(longText.text().substr(0, 10));

If you have multiple words in the text, and want each to be limited to at most 10 chars, you could do:

var longText = $('#longText');
var text = longText.text();
var regex = /\w{11}\w*/, match;
while(match = regex.exec(text)) {
    text = text.replace(match[0], match[0].substr(0, 10));
}
longText.text(text);

For future reference, I found this code snippet at http://www.mycsharpcorner.com/Post.aspx?postID=15 If you need to search for different "tags" it works very well.

    public static string[] GetStringInBetween(string strBegin,
        string strEnd, string strSource,

        string[] result ={ "", "" };
        int iIndexOfBegin = strSource.IndexOf(strBegin);
        if (iIndexOfBegin != -1)
        {
            // include the Begin string if desired
            if (includeBegin)
                iIndexOfBegin -= strBegin.Length;
            strSource = strSource.Substring(iIndexOfBegin
                + strBegin.Length);
            int iEnd = strSource.IndexOf(strEnd);
            if (iEnd != -1)
            {
                // include the End string if desired
                if (includeEnd)
                    iEnd += strEnd.Length;
                result[0] = strSource.Substring(0, iEnd);
                // advance beyond this segment
                if (iEnd + strEnd.Length < strSource.Length)
                    result[1] = strSource.Substring(iEnd
                        + strEnd.Length);
            }
        }
        else
            // stay where we are
            result[1] = strSource;
        return result;

You are modifying the list book_shop.values()[i], which is not getting updated in the dictionary. Whenever you call the values() method, it will give you the values available in dictionary, and here you are not modifying the data of the dictionary.

I don't know how it works with WingIDE, but for using PyLint with Geany, I set my external command to:

PYTHONPATH=${PYTHONPATH}:$(dirname %d) pylint --output-format=parseable --reports=n "%f"

where %f is the filename, and %d is the path. Might be useful for someone :)

If you're using ui-router you can subscribe to the $stateChangeSuccess event like this:

$rootScope.$on('$stateChangeSuccess', function (event) {
    $window.ga('send', 'pageview', $location.path());
});

I ran into the same error.

NAME         READY   STATUS             RESTARTS   AGE
pod/webapp   0/1     CrashLoopBackOff   5          47h

My problem was that I was trying to run two different pods with the same metadata name.

kind: Pod metadata: name: webapp labels: ...

To find all the names of your pods run: kubectl get pods

NAME         READY   STATUS    RESTARTS   AGE
webapp       1/1     Running   15         47h

then I changed the conflicting pod name and everything worked just fine.

NAME                 READY   STATUS    RESTARTS   AGE
webapp               1/1     Running   17         2d
webapp-release-0-5   1/1     Running   0          13m

Well you have to grab the client for that (surprise), you can either go the simple way:

var io = io.listen(server);
io.clients[sessionID].send()

Which may break, I doubt it, but it's always a possibility that io.clients might get changed, so use the above with caution

Or you keep track of the clients yourself, therefore you add them to your own clients object in the connection listener and remove them in the disconnect listener.

I would use the latter one, since depending on your application you might want to have more state on the clients anyway, so something like clients[id] = {conn: clientConnect, data: {...}} might do the job.

I've found this solution that works better for me. You can use this:

$('.modal').css({
  'width': function () { 
    return ($(document).width() * .9) + 'px';  
  },
  'margin-left': function () { 
    return -($(this).width() / 2); 
  }
});

or this depending your requirements:

$('.modal').css({
  width: 'auto',
  'margin-left': function () {
     return -($(this).width() / 2);
  }
});

See the post where I found that: https://github.com/twitter/bootstrap/issues/675

There is a third recovery mode not mentioned above. The recovery mode ultimately determines how large the LDF files become and how ofter they are written to. In cases where you are going to be doing any type of bulk inserts, you should set the DB to be in "BULK/LOGGED". This makes bulk inserts move speedily along and can be changed on the fly.

To do so,

USE master ;
ALTER DATABASE model SET RECOVERY BULK_LOGGED ;

To change it back:

USE master ;
ALTER DATABASE model SET RECOVERY FULL ;

In the spirit of adding to the conversation about why someone would not want an LDF, I add this: We do multi-dimensional modelling. Essentially we use the DB as a large store of variables that are processed in bulk using external programs. We do not EVER require rollbacks. If we could get a performance boost by turning of ALL logging, we'd take it in a heart beat.

I have these settings:

-vmargs
...
-Duser.name=...
-XX:PermSize=256m
-XX:MaxPermSize=256m
-Xmn128m
-Xms256m
-Xmx768m

Eclipse randomly crashed before I set the PermSize equal to MaxPermSize.

The answer above is kind of correct, you can't gracefully control how much native memory a java process allocates. It depends on what your application is doing.

That said, depending on platform, you may be able to do use some mechanism, ulimit for example, to limit the size of a java or any other process.

Just don't expect it to fail gracefully if it hits that limit. Native memory allocation failures are much harder to handle than allocation failures on the java heap. There's a fairly good chance the application will crash but depending on how critical it is to the system to keep the process size down that might still suit you.

On Ubuntu 18.04 I needed to use OpenJDK 1.7 for the maintenance of an old project. I downloaded the binary package. But when I executed my script on it I got the same error.

The solution was to remove the cacerts file of the downloaded JDK in the jre/lib/security folder and then to create it as symlink to the systems cacerts file in /etc/ssl/certs/java/:

sudo ln -s /etc/ssl/certs/java/cacerts /path/to/downloaded/java/jre/lib/security/cacerts

use this one

int number = (int) Double.parseDouble(s);

You need to provide a selector with higher specificity than the one in Main.css. With that selector, set the values of the properties you want to their default, e.g.

body .c1 {
    height: auto;
}

There is no "default" value that will work for all properties, you need to look up what the default is for each one and use that.

There is another open-source tool which allows you to save all console.log output in a file on your server - JS LogFlush (plug!).

JS LogFlush is an integrated JavaScript logging solution which include:

• cross-browser UI-less replacement of console.log - on client side.
• log storage system - on server side.

  • right click on Node.js command prompt
  • click on Run as administrator

• ping registry.npmjs.org

• npm view npm version

• cd %ProgramFiles%\nodejs

• npm install npm@latest

and npm updated successfully. Earlier I was trying for CMD and that was throwing error. may be some path issue that got resolved by running NodeJs Command Prompt. hope it'll work for you. try this.

Firstly you need to add a where T:class constraint - you can't call GetValue on value types unless they're passed by ref.

Secondly GetValue is very slow and gets called a lot.

To get round this we can create a delegate and call that instead:

MethodInfo method = property.GetGetMethod(true);
Delegate.CreateDelegate(typeof(Func<TClass, TProperty>), method );

The problem is that we don't know TProperty, but as usual on here Jon Skeet has the answer - we can use reflection to retrieve the getter delegate, but once we have it we don't need to reflect again:

public class ReflectionUtility
{
    internal static Func<object, object> GetGetter(PropertyInfo property)
    {
        // get the get method for the property
        MethodInfo method = property.GetGetMethod(true);

        // get the generic get-method generator (ReflectionUtility.GetSetterHelper<TTarget, TValue>)
        MethodInfo genericHelper = typeof(ReflectionUtility).GetMethod(
            "GetGetterHelper",
            BindingFlags.Static | BindingFlags.NonPublic);

        // reflection call to the generic get-method generator to generate the type arguments
        MethodInfo constructedHelper = genericHelper.MakeGenericMethod(
            method.DeclaringType,
            method.ReturnType);

        // now call it. The null argument is because it's a static method.
        object ret = constructedHelper.Invoke(null, new object[] { method });

        // cast the result to the action delegate and return it
        return (Func<object, object>) ret;
    }

    static Func<object, object> GetGetterHelper<TTarget, TResult>(MethodInfo method)
        where TTarget : class // target must be a class as property sets on structs need a ref param
    {
        // Convert the slow MethodInfo into a fast, strongly typed, open delegate
        Func<TTarget, TResult> func = (Func<TTarget, TResult>) Delegate.CreateDelegate(typeof(Func<TTarget, TResult>), method);

        // Now create a more weakly typed delegate which will call the strongly typed one
        Func<object, object> ret = (object target) => (TResult) func((TTarget) target);
        return ret;
    }
}

So now your method becomes:

public static DataTable ToDataTable<T>(this IEnumerable<T> items) 
    where T: class
{  
    // ... create table the same way

    var propGetters = new List<Func<T, object>>();
foreach (var prop in props)
    {
        Func<T, object> func = (Func<T, object>) ReflectionUtility.GetGetter(prop);
        propGetters.Add(func);
    }

    // Add the property values per T as rows to the datatable
    foreach (var item in items) 
    {  
        var values = new object[props.Length];  
        for (var i = 0; i < props.Length; i++) 
        {
            //values[i] = props[i].GetValue(item, null);   
            values[i] = propGetters[i](item);
        }    

        table.Rows.Add(values);  
    } 

    return table; 
} 

You could further optimise it by storing the getters for each type in a static dictionary, then you will only have the reflection overhead once for each type.

Try GetElementsByTagName method of XMLDocument class to read specific data or LoadXml method to read all data to xml document.

You can use SSH and SFTP as suggested here.

1. In the Guest OS (Mac OS X), open System Preferences > Sharing, then activate Remote Login; note the ip address specified in the Remote Login instructions, e.g. ssh [email protected]
2. In VirtualBox, open Devices > Network > Network Settings > Advanced > Port Forwarding and specify Host IP = 127.0.0.1, Host Port 2222, Guest IP 10.0.2.15, Guest Port 22
3. On the Host OS, run the following command sftp -P 2222 [email protected]; if you prefer a graphical interface, you can use FileZilla

Replace user and 10.0.2.15 with the appropriate values relevant to your configuration.

Probably the most definitive is Figure B.1(d) of the ggplot2 book, the appendices of which are available at http://ggplot2.org/book/appendices.pdf.

However, it is not quite that simple. hjust and vjust as described there are how it works in geom_text and theme_text (sometimes). One way to think of it is to think of a box around the text, and where the reference point is in relation to that box, in units relative to the size of the box (and thus different for texts of different size). An hjust of 0.5 and a vjust of 0.5 center the box on the reference point. Reducing hjust moves the box right by an amount of the box width times 0.5-hjust. Thus when hjust=0, the left edge of the box is at the reference point. Increasing hjust moves the box left by an amount of the box width times hjust-0.5. When hjust=1, the box is moved half a box width left from centered, which puts the right edge on the reference point. If hjust=2, the right edge of the box is a box width left of the reference point (center is 2-0.5=1.5 box widths left of the reference point. For vertical, less is up and more is down. This is effectively what that Figure B.1(d) says, but it extrapolates beyond [0,1].

But, sometimes this doesn't work. For example

DF <- data.frame(x=c("a","b","cdefghijk","l"),y=1:4)
p <- ggplot(DF, aes(x,y)) + geom_point()

p + opts(axis.text.x=theme_text(vjust=0))
p + opts(axis.text.x=theme_text(vjust=1))
p + opts(axis.text.x=theme_text(vjust=2))

The three latter plots are identical. I don't know why that is. Also, if text is rotated, then it is more complicated. Consider

p + opts(axis.text.x=theme_text(hjust=0, angle=90))
p + opts(axis.text.x=theme_text(hjust=0.5 angle=90))
p + opts(axis.text.x=theme_text(hjust=1, angle=90))
p + opts(axis.text.x=theme_text(hjust=2, angle=90))

The first has the labels left justified (against the bottom), the second has them centered in some box so their centers line up, and the third has them right justified (so their right sides line up next to the axis). The last one, well, I can't explain in a coherent way. It has something to do with the size of the text, the size of the widest text, and I'm not sure what else.

Your problem is that the top and left properties require a unit of measure, not just a bare number:

div.style.top = "200px";
div.style.left = "200px";

Answer A

None of the answers above pointed out why you might not see some of your prints. This is also because here you are dealing with streams (I didn't know this) and stream has something called orientation. Let me cite something from this source:

Narrow and wide orientation

A newly opened stream has no orientation. The first call to any I/O function establishes the orientation.

A wide I/O function makes the stream wide-oriented, a narrow I/O function makes the stream narrow-oriented. Once set, the orientation can only be changed with freopen.

Narrow I/O functions cannot be called on a wide-oriented stream; wide I/O functions cannot be called on a narrow-oriented stream. Wide I/O functions convert between wide and multibyte characters as if by calling mbrtowc and wcrtomb. Unlike the multibyte character strings that are valid in a program, multibyte character sequences in the file may contain embedded nulls and do not have to begin or end in the initial shift state.

So once you use printf() your orientation becomes narrow and from this point on you can't get anything out of wprintf() and you realy don't. Unless you use freeopen() which is intended to be used on files.

Answer B

As it turns out you can use freeopen() like this:

freopen(NULL, "w", stdout);             

To make stream "not defined" again. Try this example:

#include <stdio.h>
#include <wchar.h>
#include <locale.h>

int main(void)
{
    // We set locale which is the same as the enviromental variable "LANG=en_US.UTF-8".
    setlocale(LC_ALL, "en_US.UTF-8");

    // We define array of wide characters. We indicate this on both sides of equal sign
    // with "wchar_t" on the left and "L" on the right.
    wchar_t y[100] = L"€? ???a??p???? e? a??? est??\n";

    // We print header in ASCII characters
    wprintf(L"content-type:text/html; charset:utf-8\n\n");

    // A newly opened stream has no orientation. The first call to any I/O function
    // establishes the orientation: a wide I/O function makes the stream wide-oriented,
    // a narrow I/O function makes the stream narrow-oriented. Once set, we must respect
    // this, so for the time being we are stuck with either printf() or wprintf().

    wprintf(L"%S\n", y);    // Conversion specifier %S is not standardized (!)
    wprintf(L"%ls\n", y);   // Conversion specifier %s with length modifier %l is 
                            // standardized (!)

    // At this point curent orientation of the stream is wide and this is why folowing
    // narrow function won't print anything! Whether we should use wprintf() or printf()
    // is primarily a question of how we want output to be encoded.

    printf("1\n");          // Print narrow string of characters with a narrow function
    printf("%s\n", "2");    // Print narrow string of characters with a narrow function
    printf("%ls\n",L"3");   // Print wide string of characters with a narrow function

    // Now we reset the stream to no orientation.
    freopen(NULL, "w", stdout);

    printf("4\n");          // Print narrow string of characters with a narrow function
    printf("%s\n", "5");    // Print narrow string of characters with a narrow function
    printf("%ls\n",L"6");   // Print wide string of characters with a narrow function

    return 0;
}

Rails >= 3.2 (including Rails 4+ and 5+):

class Countries < ActiveRecord::Base
  self.table_name = "cc"
end

Rails <= 3.1:

end

A lazy val is most easily understood as a "memoized (no-arg) def".

Like a def, a lazy val is not evaluated until it is invoked. But the result is saved so that subsequent invocations return the saved value. The memoized result takes up space in your data structure, like a val.

As others have mentioned, the use cases for a lazy val are to defer expensive computations until they are needed and store their results, and to solve certain circular dependencies between values.

Lazy vals are in fact implemented more or less as memoized defs. You can read about the details of their implementation here:

http://docs.scala-lang.org/sips/pending/improved-lazy-val-initialization.html

Java does not support multiple inheritance, that's why you can't extend a class from two different classes at the same time.

Rather, use a single class to extend from, and use interfaces to include additional functionality.

The function fromJSON() in RJSONIO, rjson and jsonlite don't return a simple 2D data.frame for complex nested json objects.

To overcome this you can use tidyjson. It takes in a json and always returns a data.frame. It is currently not availble in CRAN, you can get it here: https://github.com/sailthru/tidyjson

Update: tidyjson is now available in cran, you can install it directly using install.packages("tidyjson")

ExecutorService is newer and more general. A timer is just a thread that periodically runs stuff you have scheduled for it.

An ExecutorService may be a thread pool, or even spread out across other systems in a cluster and do things like one-off batch execution, etc...

Just look at what each offers to decide.

And if anyone is wondering how to do this in swift:

if let myDelegate = UIApplication.sharedApplication().delegate as? AppDelegate {
   myDelegate.someMethod()
}

@echo off
title Command Executer
color 1b

echo Command Executer by: YourNameHere
echo #################################
: execute
echo Please Type A Command Here:
set /p cmd=Command:
%cmd%
goto execute

docker start `docker ps -a | awk '{print $1}'`

This will start up all the containers that are in the 'Exited' state

To customize tool bar style, first create tool bar custom style inheriting Widget.AppCompat.Toolbar, override properties and then add it to custom app theme as shown below, see http://www.zoftino.com/android-toolbar-tutorial for more information tool bar and styles.

   <style name="MyAppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="toolbarStyle">@style/MyToolBarStyle</item>
    </style>
    <style name="MyToolBarStyle" parent="Widget.AppCompat.Toolbar">
        <item name="android:background">#80deea</item>
        <item name="titleTextAppearance">@style/MyTitleTextAppearance</item>
        <item name="subtitleTextAppearance">@style/MySubTitleTextAppearance</item>
    </style>
    <style name="MyTitleTextAppearance" parent="TextAppearance.Widget.AppCompat.Toolbar.Title">
        <item name="android:textSize">35dp</item>
        <item name="android:textColor">#ff3d00</item>
    </style>
    <style name="MySubTitleTextAppearance" parent="TextAppearance.Widget.AppCompat.Toolbar.Subtitle">
        <item name="android:textSize">30dp</item>
        <item name="android:textColor">#1976d2</item>
    </style>

Just ignore everything but digits.

Here is what I use:

// USA phones should contain at least 10 digits. For Ukrainian phones it's OK to have only 9 digits, without leading 0 and country code prefix: [+380] 88 888-88-88.
String.prototype.isValidPhone = function(digitsCount) {
  var str = this.trim().match(/\d/g);
  return str && str.length >= (digitsCount || 10); // default is at least 10 digits
}

You must use an aggregate function on the columns against which you are not grouping. In this example, I arbitrarily picked the Min function. You are combining the rows with the same FruitType value. If I have two rows with the same FruitType value but different Fruit_Id values for example, what should the system do?

Select Min(tblFruit_id) As tblFruit_id
    , tblFruit_FruitType
From tblFruit
Group By tblFruit_FruitType

SQL Fiddle example

\b matches at word boundaries (without actually matching any characters), so the following should do what you want:

\bstackoverflow\b

You can do it like this:

In your main view controller:

func showModal() {
    let modalViewController = ModalViewController()
    modalViewController.modalPresentationStyle = .overCurrentContext
    presentViewController(modalViewController, animated: true, completion: nil)
}

In your modal view controller:

class ModalViewController: UIViewController {
    override func viewDidLoad() {
        view.backgroundColor = UIColor.clearColor()
        view.opaque = false
    }
}

If you are working with a storyboard:

Just add a Storyboard Segue with Kind set to Present Modally to your modal view controller and on this view controller set the following values:

• Background = Clear Color
• Drawing = Uncheck the Opaque checkbox
• Presentation = Over Current Context

As Crashalot pointed out in his comment: Make sure the segue only uses Default for both Presentation and Transition. Using Current Context for Presentation makes the modal turn black instead of remaining transparent.

This comment syntax should work for you:

@* enter comments here *@

In SQL Server 2012 it is possible to use FORMAT(@mydate, 'MMMM') AS MonthName

You can use twiny to create 2 x-axis scales. For Example:

import numpy as np
import matplotlib.pyplot as plt

fig = plt.figure()
ax1 = fig.add_subplot(111)
ax2 = ax1.twiny()

a = np.cos(2*np.pi*np.linspace(0, 1, 60.))

ax1.plot(range(60), a)
ax2.plot(range(100), np.ones(100)) # Create a dummy plot
ax2.cla()
plt.show()

Ref: http://matplotlib.sourceforge.net/faq/howto_faq.html#multiple-y-axis-scales

Output:

1) Locate the my.ini, which store in the MySQL installation folder.

For example,

C:\Program Files\MySQL\MySQL Server 5.1\my.ini

2) Open the “my.ini” with our favor text editor.

#Path to installation directory. All paths are usually resolved relative to this.
basedir="C:/Program Files/MySQL/MySQL Server 5.1/"

#Path to the database root/"
datadir="C:/Documents and Settings/All Users/Application Data/MySQL/MySQL Server 5.1/Data

Find the “datadir”, this is the where does MySQL stored the data in Windows.

You can use the following if you want to specify tricky formats:

df['date_col'] =  pd.to_datetime(df['date_col'], format='%d/%m/%Y')

More details on format here:

• Python 2 https://docs.python.org/2/library/datetime.html#strftime-strptime-behavior
• Python 3 https://docs.python.org/3.7/library/datetime.html#strftime-strptime-behavior

XMLHttpRequest is a built-in object in web browsers.

It is not distributed with Node; you have to install it separately,

1. Install it with npm,

   npm install xmlhttprequest
   

2. Now you can require it in your code.

   var XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
   var xhr = new XMLHttpRequest();
   

That said, the http module is the built-in tool for making HTTP requests from Node.

Axios is a library for making HTTP requests which is available for Node and browsers that is very popular these days.

The following is an example of using SharedPreferences to achieve a 'forWhat' check.

    preferences = PreferenceManager.getDefaultSharedPreferences(context);
    preferencesEditor = preferences.edit();
public static boolean isFirstRun(String forWhat) {
    if (preferences.getBoolean(forWhat, true)) {
        preferencesEditor.putBoolean(forWhat, false).commit();
        return true;
    } else {
        return false;
    }
}

This is something you solve in the "controller", which is the point of logicless templating.

// some function that retreived data through ajax
function( view ){

   if ( !view.avatar ) {
      // DEFAULTS can be a global settings object you define elsewhere
      // so that you don't have to maintain these values all over the place
      // in your code.
      view.avatar = DEFAULTS.AVATAR;
   }

   // do template stuff here

}

This is actually a LOT better then maintaining image url's or other media that might or might not change in your templates, but takes some getting used to. The point is to unlearn template tunnel vision, an avatar img url is bound to be used in other templates, are you going to maintain that url on X templates or a single DEFAULTS settings object? ;)

Another option is to do the following:

// augment view
view.hasAvatar = !!view.avatar;
view.noAvatar = !view.avatar;

And in the template:

{{#hasAvatar}}
    SHOW AVATAR
{{/hasAvatar}}
{{#noAvatar}}
    SHOW DEFAULT
{{/noAvatar}}

But that's going against the whole meaning of logicless templating. If that's what you want to do, you want logical templating and you should not use Mustache, though do give it yourself a fair chance of learning this concept ;)

On vb.net you must write @ModelType.

Go through C:\apache-tomcat-7.0.47\lib path (this path may be differ based on where you installed the Tomcat server) then past ojdbc14.jar if its not contain.

Then restart the server in eclipse then run your app on server

In Typescript and ES6 you can also use for..of:

for (var product of products) {
     console.log(product.product_desc)
}

which will be transcoded to javascript:

for (var _i = 0, products_1 = products; _i < products_1.length; _i++) {
    var product = products_1[_i];
    console.log(product.product_desc);
}

I would think of one more case when pessimistic locking would be a better choice.

For optimistic locking every participant in data modification must agree in using this kind of locking. But if someone modifies the data without taking care about the version column, this will spoil the whole idea of the optimistic locking.

String is present in package java.lang which is imported by default in all java programs.

It depends on the configuration of the application as well as on IIS as this gentleman in the below link has rightfully explained. Please see his article below
