As indicated here, the general syntax for the first solution proposed by Tony Andrews is :

update some_table s
set   (s.col1, s.col2) = (select x.col1, x.col2
                          from   other_table x
                          where  x.key_value = s.key_value
                         )
where exists             (select 1
                          from   other_table x
                          where  x.key_value = s.key_value
                         )

I think this is interesting especially if you want update more than one field.

Option 2 is correct.

The nested list should be inside a <li> element of the list in which it is nested.

Link to the W3C Wiki on Lists (taken from comment below): HTML Lists Wiki.

Link to the HTML5 W3C ul spec: HTML5 ul. Note that a ul element may contain exactly zero or more li elements. The same applies to HTML5 ol. The description list (HTML5 dl) is similar, but allows both dt and dd elements.

More Notes:

• dl = definition list.
• ol = ordered list (numbers).
• ul = unordered list (bullets).

You call tarfile.open with mode='w:gz', meaning "Open for gzip compressed writing."

You'll probably want to end the filename (the name argument to open) with .tar.gz, but that doesn't affect compression abilities.

BTW, you usually get better compression with a mode of 'w:bz2', just like tar can usually compress even better with bzip2 than it can compress with gzip.

I'm using Android Studio 0.5.2. So if your version is lower than mine my answer may not work for you.

3 ways to add a new Jar to your project:

1. Menu under Files-->Project Structure
2. Just press 'F4'
3. under Project navigation, right clink on any java library and a context menu will show then click on 'Open Library Settings'

A Project Structure window will popup.

On the left column click on 'Libraries' then look at the right pane where there is a plus sign '+' and click on it then enter the path to your new library.

Make sure the new library is under the 'project\libs\' folder otherwise you may get a broken link when you save your project source code.

I adopted the script from shiplu.mokadd.im to fit my needs. Whom it interests:

#!/bin/bash
if [ "$#" -lt 2 ]; then
    if [ "$#" -lt 1 ]; then 
        echo "usage: $0 [path to csv file] <table name> > [sql filename]"
        exit 1
    fi
    TABLENAME=$1
else
    TABLENAME=$2
fi
echo "CREATE TABLE $TABLENAME ( "
FIRSTLINE=$(head -1 $1)
# convert lowercase characters to uppercase
FIRSTLINE=$(echo $FIRSTLINE | tr '[:lower:]' '[:upper:]')
# remove spaces
FIRSTLINE=$(echo $FIRSTLINE | sed -e 's/ /_/g')
# add tab char to the beginning of line
FIRSTLINE=$(echo "\t$FIRSTLINE")
# add tabs and newline characters
FIRSTLINE=$(echo $FIRSTLINE | sed -e 's/,/,\\n\\t/g')
# add VARCHAR
FIRSTLINE=$(echo $FIRSTLINE | sed -e 's/,/ VARCHAR(255),/g')
# print out result
echo -e $FIRSTLINE" VARCHAR(255));"

The Problem is the Container that gets the smallest possible size.

Just give a width: to the Container (in red) and you are done.

width: MediaQuery.of(context).size.width

  new Positioned(
  bottom: 0.0,
  child: new Container(
    width: MediaQuery.of(context).size.width,
    color: Colors.red,
    margin: const EdgeInsets.all(0.0),
    child: new Column(
      mainAxisAlignment: MainAxisAlignment.center,
      children: <Widget>[
        new Align(
          alignment: Alignment.bottomCenter,
          child: new ButtonBar(
            alignment: MainAxisAlignment.center,
            children: <Widget>[
              new OutlineButton(
                onPressed: null,
                child: new Text(
                  "Login",
                  style: new TextStyle(color: Colors.white),
                ),
              ),
              new RaisedButton(
                color: Colors.white,
                onPressed: null,
                child: new Text(
                  "Register",
                  style: new TextStyle(color: Colors.black),
                ),
              )
            ],
          ),
        )
      ],
    ),
  ),
),

Given an array you can use the Array.ConvertAll method:

int[] myInts = Array.ConvertAll(arr, s => int.Parse(s));

Thanks to Marc Gravell for pointing out that the lambda can be omitted, yielding a shorter version shown below:

int[] myInts = Array.ConvertAll(arr, int.Parse);

A LINQ solution is similar, except you would need the extra ToArray call to get an array:

int[] myInts = arr.Select(int.Parse).ToArray();

i did this and works: i have my project in D: and my batch file is in the desktop, if u have it in the same drive just ignore the first line and change de D directory in the second line

in the second line change the folder of the file, put your folder

in the third line change the name of the file

D: cd D:\python_proyects\example_folder\ python example_file.py

The correct way of building client/server Microsoft Access applications where the data is stored in a RDBMS is to use the Linked Table method. This ensures Data Isolation and Concurrency is maintained between the Microsoft Access client application and the RDBMS data with no additional and unnecessary programming logic and code which makes maintenance more difficult, and adds to development time.

Use selectionStart/selectionEnd properties of the input element (works for <textarea> as well)

function insertAtCursor(myField, myValue) {
    //IE support
    if (document.selection) {
        myField.focus();
        sel = document.selection.createRange();
        sel.text = myValue;
    }
    //MOZILLA and others
    else if (myField.selectionStart || myField.selectionStart == '0') {
        var startPos = myField.selectionStart;
        var endPos = myField.selectionEnd;
        myField.value = myField.value.substring(0, startPos)
            + myValue
            + myField.value.substring(endPos, myField.value.length);
    } else {
        myField.value += myValue;
    }
}

Use filter-branch:

git filter-branch --force --index-filter 'git rm --cached --ignore-unmatch *file_path_relative_to_git_repo*' --prune-empty --tag-name-filter cat -- --all

git push origin *branch_name* -f

This should work

DataSet ds = new DataSet();
SqlDataAdapter da = new SqlDataAdapter(sqlString, sqlConn);
da.Fill(ds);

if(ds.Tables.Count > 0)
{
  // enter code here
}

In the same shell, hold ctrl key and press keys p then q

Have you set AcceptsReturn property to true?

The Path.GetFileNameWithoutExtension method gives you the filename you pass as an argument without the extension, as should be obvious from the name.

require_once('db/connect.php');

//rand(1000000 , 9999999);

$products_query = "SELECT id FROM products";
$products_result = mysqli_query($conn, $products_query);
$products_row = mysqli_fetch_array($products_result);
$ids_array = [];

do
{
    array_push($ids_array, $products_row['id']);
}
while($products_row = mysqli_fetch_array($products_result));

/*
echo '<pre>';
print_r($ids_array);
echo '</pre>';
*/
$row_counter = count($ids_array);

for ($i=0; $i < $row_counter; $i++)
{ 
    $current_row = $ids_array[$i];
    $rand = rand(1000000 , 9999999);
    mysqli_query($conn , "UPDATE products SET code='$rand' WHERE id='$current_row'");
}

You can call $setUnion on a single array, which also filters dupes:

{ $project: {Package: 1, deps: {'$setUnion': '$deps.Package'}}}

I think you can use db.collection.distinct(fields,query)

You will be able to get the distinct values in your case for NetworkID.

It should be something like this :

Db.collection.distinct('NetworkID')

On Chrome, you should be able to do this using the benchmarking extension. You need to start your chrome with the following switches:

./chrome --enable-benchmarking --enable-net-benchmarking 

In Chrome's console now you can do the following:

chrome.benchmarking.clearCache();
chrome.benchmarking.clearHostResolverCache();
chrome.benchmarking.clearPredictorCache();
chrome.benchmarking.closeConnections();

As you can tell from above commands, it not only clears the browser cache, but also clears the DNS cache and closes network connections. These are great when you're doing page load time benchmarking. Obviously you don't have to use them all if not needed (e.g. clearCache() should suffice if you need to clear the cache only and don't care about DNS cache and connections).

Add these two properties to your parent layout (ex: Linear Layout, Relative Layout)

android:focusable="false"
android:focusableInTouchMode="false" 

It will do the trick :)

Comment:

Platform: Windows Server 2012 Standart- 64Bit - IIS 8

In addition to previously provided answers, one option is to follow the 'localhost exception' approach to create the first user if your db is already started with access control (--auth switch). In order to do that, you need to have localhost access to the server and then run:

mongo
use admin
db.createUser(
 {
     user: "user_name",
     pwd: "user_pass",
     roles: [
           { role: "userAdminAnyDatabase", db: "admin" },
           { role: "readWriteAnyDatabase", db: "admin" },
           { role: "dbAdminAnyDatabase", db: "admin" }
        ]
 })

As stated in MongoDB documentation:

The localhost exception allows you to enable access control and then create the first user in the system. With the localhost exception, after you enable access control, connect to the localhost interface and create the first user in the admin database. The first user must have privileges to create other users, such as a user with the userAdmin or userAdminAnyDatabase role. Connections using the localhost exception only have access to create the first user on the admin database.

Here is the link to that section of the docs.

You could use TimeZoneInfo class

The TimeZone class recognizes local time zone, and can convert times between Coordinated Universal Time (UTC) and local time. A TimeZoneInfo object can represent any time zone, and methods of the TimeZoneInfo class can be used to convert the time in one time zone to the corresponding time in any other time zone. The members of the TimeZoneInfo class support the following operations:

1. Retrieving a time zone that is already defined by the operating system.

2. Enumerating the time zones that are available on a system.

3. Converting times between different time zones.

4. Creating a new time zone that is not already defined by the operating system.

   Serializing a time zone for later retrieval.

Assuming your row number is in B1, you can use INDIRECT:

=INDIRECT("A" & B1)

This takes a cell reference as a string (in this case, the concatenation of A and the value of B1 - 5), and returns the value at that cell.

I'm not sure why previous answers haven't suggested that the original poster set up a shell profile (bashrc, .tcshrc, etc.) that executed their commands automatically every time they log in on the server side.

The quest that brought me to this page for help was a bit different -- I wanted multiple PuTTY shortcuts for the same host that would execute different startup commands.

I came up with two solutions, both of which worked:

(background) I have a folder with a variety of PuTTY shortcuts, each with the "target" property in the shortcut tab looking something like:

"C:\Program Files (x86)\PuTTY\putty.exe" -load host01

with each load corresponding to a PuTTY profile I'd saved (with different hosts in the "Session" tab). (Mostly they only differ in color schemes -- I like to have each group of related tasks share a color scheme in the terminal window, with critical tasks, like logging in as root on a production system, performed only in distinctly colored windows.)

The folder's Windows properties are set to very clean and stripped down -- it functions as a small console with shortcut icons for each of my frequent remote PuTTY and RDP connections.

(solution 1) As mentioned in other answers the -m switch is used to configure a script on the Windows side to run, the -t switch is used to stay connected, but I found that it was order-sensitive if I wanted to get it to run without exiting

What I finally got to work after a lot of trial and error was:

(shortcut target field):

"C:\Program Files (x86)\PuTTY\putty.exe" -t -load "SSH Proxy" -m "C:\Users\[me]\Documents\hello-world-bash.txt"

where the file being executed looked like

echo "Hello, World!"
echo ""
export PUTTYVAR=PROXY
/usr/local/bin/bash

(no semicolons needed)

This runs the scripted command (in my case just printing "Hello, world" on the terminal) and sets a variable that my remote session can interact with.

Note for debugging: when you run PuTTY it loads the -m script, if you edit the script you need to re-launch PuTTY instead of just restarting the session.

(solution 2) This method feels a lot cleaner, as the brains are on the remote Unix side instead of the local Windows side:

From Putty master session (not "edit settings" from existing session) load a saved config and in the SSH tab set remote command to:

export PUTTYVAR=GREEN; bash -l

Then, in my .bashrc, I have a section that performs different actions based on that variable:

case ${PUTTYVAR} in
  "")
    echo "" 
    ;;
  "PROXY")
    # this is the session config with all the SSH tunnels defined in it
    echo "";
    echo "Special window just for holding tunnels open." ;
    echo "";
    PROMPT_COMMAND='echo -ne "\033]0;Proxy Session @master01\$\007"'
    alias temppass="ssh keyholder.example.com makeonetimepassword"
    alias | grep temppass
    ;;
  "GREEN")
    echo "";
    echo "It's not easy being green"
    ;;
  "GRAY")
    echo ""
    echo "The gray ghost"
    ;;
  *)
    echo "";
    echo "Unknown PUTTYVAR setting ${PUTTYVAR}"
    ;;
esac

(solution 3, untried)

It should also be possible to have bash skip my .bashrc and execute a different startup script, by putting this in the PuTTY SSH command field:

bash --rcfile .bashrc_variant -l 

Use the <sup></sup>tag (<sub></sub> is the equivalent for subscripts). See this gist for an example.

If the formula already exists in a cell you can fill it down as follows:

• Select the cell containing the formula and press CTRL+SHIFT+DOWN to select the rest of the column (CTRL+SHIFT+END to select up to the last row where there is data)
• Fill down by pressing CTRL+D
• Use CTRL+UP to return up

On Mac, use CMD instead of CTRL.

An alternative if the formula is in the first cell of a column:

• Select the entire column by clicking the column header or selecting any cell in the column and pressing CTRL+SPACE
• Fill down by pressing CTRL+D

I had to deal with wkhtmltopdf too.

I'm using Bootstrap 3.3.7 as Framework and need to avoid page break on .row element.

I did the job using those settings:

.myContainer {
    display: grid;
    page-break-inside: avoid;
}

No need to wrap in @media print

You can also do as a convenience:

df[:10]

The git package installed on your system includes bash files to aid you in creating an informative prompt. To create colors, you will need to insert terminal escape sequences into your prompt. And, the final ingredient is to update your prompt after each command gets executed by using the built-in variable PROMPT_COMMAND.

Edit your ~/.bashrc to include the following, and you should get the prompt in your question, modulo some color differences.

#
# Git provides a bash file to create an informative prompt. This is its standard
# location on Linux. On Mac, you should be able to find it under your Git
# installation. If you are unable to find the file, I have a copy of it on my GitHub.
#
# https://github.com/chadversary/home/blob/42cf697ba69d4d474ca74297cdf94186430f1384/.config/kiwi-profile/40-git-prompt.sh
#
source /usr/share/git/completion/git-prompt.sh

#
# Next, we need to define some terminal escape sequences for colors. For a fuller
# list of colors, and an example how to use them, see my bash color file on my GitHub
# and my coniguration for colored man pages.
#
# https://github.com/chadversary/home/blob/42cf697ba69d4d474ca74297cdf94186430f1384/.config/kiwi-profile/10-colors.sh

#
color_start='\e['
color_end='m'
color_reset='\e[0m'
color_bg_blue='44'

#
# To get a fancy git prompt, it's not sufficient to set PS1. Instead, we set PROMPT_COMMAND,
# a built in Bash variable that gets evaluated before each render of the prompt.
#
export PROMPT_COMMAND="PS1=\"\${color_start}\${color_bg_blue}\${color_end}\u@\h [\w\$(__git_ps1 \" - %s\")]\${color_reset}\n\$ \""

#
# If you find that the working directory that appears in the prompt is ofter too long,
# then trim it.
#
export PROMPT_DIRTRIM=3

Furthermore, you also have || which is the logical or, and also ; which is just a separator which doesn't care what happend to the command before.

$ false || echo "Oops, fail"
Oops, fail

$ true || echo "Will not be printed"
$  

$ true && echo "Things went well"
Things went well

$ false && echo "Will not be printed"
$

$ false ; echo "This will always run"
This will always run

Some details about this can be found here Lists of Commands in the Bash Manual.

Many people have answered the mechanical details already, but it's worth noting: This is a poor design choice, by Java.

Java's asList method is documented as "Returns a fixed-size list...". If you take its result and call (say) the .add method, it throws an UnsupportedOperationException. This is unintuitive behavior! If a method says it returns a List, the standard expectation is that it returns an object which supports the methods of interface List. A developer shouldn't have to memorize which of the umpteen util.List methods create Lists that don't actually support all the List methods.

If they had named the method asImmutableList, it would make sense. Or if they just had the method return an actual List (and copy the backing array), it would make sense. They decided to favor both runtime-performance and short names, at the expense of violating both the Principle of Least Surprise and the good-O.O. practice of avoiding UnsupportedOperationExceptions.

(Also, the designers might have made a interface ImmutableList, to avoid a plethora of UnsupportedOperationExceptions.)

I cribbed this and added the 'px'; Works very well.

function getOffset(el) {
  el = el.getBoundingClientRect();
  return {
    left: (el.right + window.scrollX ) +'px',
    top: (el.top + window.scrollY ) +'px'
  }
}
to call: //Gets it to the right side
 el.style.top = getOffset(othis).top ; 
 el.style.left = getOffset(othis).left ; 

So before I found this post, I successfully found this to work.

Model._meta.fields

It works equally as

Model._meta.get_fields()

I'm not sure what the difference is in the results, if there is one. I ran this loop and got the same output.

for field in Model._meta.fields:
    print(field.name)

You have to first convert your object literal to a Prototype Hash:

// Store your object literal
var obj = {foo: 1, bar: 2, barobj: {75: true, 76: false, 85: true}}

// Iterate like so.  The $H() construct creates a prototype-extended Hash.
$H(obj).each(function(pair){
  alert(pair.key);
  alert(pair.value);
});

Okay, it took me a while to see this, but there's no way this compiles:

return String.(ConfigurationManager.AppSettings[paramName]);

You're not even calling a method on the String type. Just do this:

return ConfigurationManager.AppSettings[paramName];

The AppSettings KeyValuePair already returns a string. If the name doesn't exist, it will return null.

Based on your edit you have not yet added a Reference to the System.Configuration assembly for the project you're working in.

A group of 8 bits is called a byte ( with the exception where it is not :) for certain architectures )

A word is a fixed sized group of bits that are handled as a unit by the instruction set and/or hardware of the processor. That means the size of a general purpose register ( which is generally more than a byte ) is a word

In the C, a word is most often called an integer => int

ONE COLOR CASE - CSS only

Just to register my experience, where I wanted to set only the color of the selected option to a specific one.

I first tried to set by css only the color of the selected option with no success.

Then, after trying some combinations, this has worked for me with SCSS:

select {
      color: white; // color of the selected option

      option {
        color: black; // color of all the other options
      }
 }

Take a look at a working example with only CSS:

select {_x000D_
  color: yellow; // color of the selected option_x000D_
 }_x000D_
_x000D_
select option {_x000D_
  color: black; // color of all the other options_x000D_
}

<select id="mySelect">_x000D_
    <option value="apple" >Apple</option>_x000D_
    <option value="banana" >Banana</option>_x000D_
    <option value="grape" >Grape</option>_x000D_
</select>

For different colors, depending on the selected option, you'll have to deal with js.

Difference between CMD and ENTRYPOINT by intuition:

• ENTRYPOINT: command to run when container starts.
• CMD: command to run when container starts or arguments to ENTRYPOINT if specified.

Yes, it's mixing up.

You can override any of them when running docker run.

Difference between CMD and ENTRYPOINT by example:

docker run -it --rm yourcontainer /bin/bash            <-- /bin/bash overrides CMD
                                                       <-- /bin/bash does not override ENTRYPOINT
docker run -it --rm --entrypoint ls yourcontainer      <-- overrides ENTRYPOINT with ls
docker run -it --rm --entrypoint ls yourcontainer  -la  <-- overrides ENTRYPOINT with ls and overrides CMD with -la

More on difference between CMD and ENTRYPOINT:

Argument to docker run such as /bin/bash overrides any CMD command we wrote in Dockerfile.

ENTRYPOINT cannot be overriden at run time with normal commands such as docker run [args]. The args at the end of docker run [args] are provided as arguments to ENTRYPOINT. In this way we can create a container which is like a normal binary such as ls.

So CMD can act as default parameters to ENTRYPOINT and then we can override the CMD args from [args].

ENTRYPOINT can be overriden with --entrypoint.

If you need to remove it from all your plots, you can remove spines in style settings (style sheet or rcParams). E.g:

import matplotlib as mpl

mpl.rcParams['axes.spines.right'] = False
mpl.rcParams['axes.spines.top'] = False

If you want to remove all spines:

mpl.rcParams['axes.spines.left'] = False
mpl.rcParams['axes.spines.right'] = False
mpl.rcParams['axes.spines.top'] = False
mpl.rcParams['axes.spines.bottom'] = False

Use these codes to check if string contains space/spaces may it be in the first position, middle or last:

 name = firstname.getText().toString(); //name is the variable that holds the string value

 Pattern space = Pattern.compile("\\s+");
 Matcher matcherSpace = space.matcher(name);
 boolean containsSpace = matcherSpace.find();

 if(constainsSpace == true){
  //string contains space
 }
 else{
  //string does not contain any space
 }

You can use this regex to get the yyyy-MM-dd format:

((?:19|20)\\d\\d)-(0?[1-9]|1[012])-([12][0-9]|3[01]|0?[1-9])

You can find example for date validation: How to validate date with regular expression.

I am trying to parse JSON data returned from an ajax call, and the following is working for me:

Sample PHP code

$portfolio_array= Array('desc'=>'This is test description1','item1'=>'1.jpg','item2'=>'2.jpg');

echo json_encode($portfolio_array);

And in the .js, i am parsing like this:

var req=$.post("json.php", { id: "" + id + ""},
function(data) {
    data=$.parseJSON(data);
    alert(data.desc);
    $.each(data, function(i,item){
    alert(item);
    });
})
.success(function(){})
.error(function(){alert('There was problem loading portfolio details.');})
.complete(function(){});

If you have multidimensional array like below

$portfolio_array= Array('desc'=>'This is test description 1','items'=> array('item1'=>'1.jpg','item2'=>'2.jpg'));
echo json_encode($portfolio_array);

Then the code below should work:

var req=$.post("json.php", { id: "" + id + 
    function(data) {
    data=$.parseJSON(data);
    alert(data.desc);
    $.each(data.items, function(i,item){
    alert(item);
    });
})
.success(function(){})
.error(function(){alert('There was problem loading portfolio details.');})
.complete(function(){});

Please note the sub array key here is items, and suppose if you have xyz then in place of data.items use data.xyz

jsonData = """{"from": {"id": "8", "name": "Mary Pinter"}, "message": "How ARE you?", "comments": {"count": 0}, "updated_time": "2012-05-01", "created_time": "2012-05-01", "to": {"data": [{"id": "1543", "name": "Honey Pinter"}, {"name": "Joe Schmoe"}]}, "type": "status", "id": "id_7"}"""

def getTargetIds(jsonData):
    data = json.loads(jsonData)
    for dest in data['to']['data']:
        print("to_id:", dest.get('id', 'null'))

Try it:

>>> getTargetIds(jsonData)
to_id: 1543
to_id: null

Or, if you just want to skip over values missing ids instead of printing 'null':

def getTargetIds(jsonData):
    data = json.loads(jsonData)
    for dest in data['to']['data']:
        if 'id' in to_id:
            print("to_id:", dest['id'])

So:

>>> getTargetIds(jsonData)
to_id: 1543

Of course in real life, you probably don't want to print each id, but to store them and do something with them, but that's another issue.

As @kgrad says, /* */ does not nest and can cause errors. A better answer is:

// LINE *of code* I WANT COMMENTED 
// LINE *of code* I WANT COMMENTED 
// LINE *of code* I WANT COMMENTED 

Most IDEs have a single keyboard command for doing/undoing this, so there's really no reason to use the other style any more. For example: in eclipse, select the block of text and hit Ctrl+/
To undo that type of comment, use Ctrl+\

UPDATE: The Sun coding convention says that this style should not be used for block text comments:

// Using the slash-slash
// style of comment as shown
// in this paragraph of non-code text is 
// against the coding convention.

but // can be used 3 other ways:

1. A single line comment
2. A comment at the end of a line of code
3. Commenting out a block of code

While there is no technical difference, I have seen the two used to denote slightly different things.

For a template that should accept any type as T, including built-ins (such as an array )

template<typename T>
class Foo { ... }

For a template that will only work where T is a real class.

template<class T>
class Foo { ... }

But keep in mind that this is purely a style thing some people use. Not mandated by the standard or enforced by compilers

Scenario:

I am working on a multi-module Gradle project.

Modules are:

- core, 
- service,
- geo,
- report,
- util and
- some other modules.

So primarily we have prepared a Component[locationRecommendHttpClientBuilder] in geo module.

Java Code:

import org.springframework.stereotype.Component

@Component("locationRecommendHttpClientBuilder")
class LocationRecommendHttpClientBuilder extends PanaromaHttpClientBuilder {
    @Override
    PanaromaHttpClient buildFromConfiguration() {
        this.setURL(PanaromaConf.getInstance().getString("locationrecommend.url"))
        this.setMethod(PanaromaConf.getInstance().getString("locationrecommend.method"))
        this.setProxyHost(PanaromaConf.getInstance().getString("locationrecommend.proxy.host"))
        this.setProxyPort(PanaromaConf.getInstance().getInt("locationrecommend.proxy.port", 0))
        return super.build()
    }
}

application-context.xml

<bean id="locationRecommendHttpClient"
      class="au.co.google.panaroma.platform.logic.impl.PanaromaHttpClient"
      scope="singleton" factory-bean="locationRecommendHttpClientBuilder"
      factory-method="buildFromConfiguration" />

Then it is decided to add this component in core module.

One engineer has previous code for geo module and then he has taken the latest module of core but he forgot to take the latest geo module.

So the component[locationRecommendHttpClientBuilder] is double times in his project and he was getting the following error.

Caused by: org.springframework.context.annotation.ConflictingBeanDefinitionException: Annotation-specified bean name 'LocationRecommendHttpClientBuilder' for bean class [au.co.google.app.locationrecommendation.builder.LocationRecommendHttpClientBuilder] conflicts with existing, non-compatible bean definition of same name and class [au.co.google.panaroma.platform.logic.impl.locationRecommendHttpClientBuilder]

Solution Procedure:

After removal the component from geo module, component[locationRecommendHttpClientBuilder] is only available in core module. So there is no conflicting situation. Issue is solved by this way.

This will split it differently to what you have, but is still quite a nice list structure I think:

chunk.2 <- function(x, n, force.number.of.groups = TRUE, len = length(x), groups = trunc(len/n), overflow = len%%n) { 
  if(force.number.of.groups) {
    f1 <- as.character(sort(rep(1:n, groups)))
    f <- as.character(c(f1, rep(n, overflow)))
  } else {
    f1 <- as.character(sort(rep(1:groups, n)))
    f <- as.character(c(f1, rep("overflow", overflow)))
  }
  
  g <- split(x, f)
  
  if(force.number.of.groups) {
    g.names <- names(g)
    g.names.ordered <- as.character(sort(as.numeric(g.names)))
  } else {
    g.names <- names(g[-length(g)])
    g.names.ordered <- as.character(sort(as.numeric(g.names)))
    g.names.ordered <- c(g.names.ordered, "overflow")
  }
  
  return(g[g.names.ordered])
}

Which will give you the following, depending on how you want it formatted:

> x <- 1:10; n <- 3
> chunk.2(x, n, force.number.of.groups = FALSE)
$`1`
[1] 1 2 3

$`2`
[1] 4 5 6

$`3`
[1] 7 8 9

$overflow
[1] 10

> chunk.2(x, n, force.number.of.groups = TRUE)
$`1`
[1] 1 2 3

$`2`
[1] 4 5 6

$`3`
[1]  7  8  9 10

Running a couple of timings using these settings:

set.seed(42)
x <- rnorm(1:1e7)
n <- 3

Then we have the following results:

> system.time(chunk(x, n)) # your function 
   user  system elapsed 
 29.500   0.620  30.125 

> system.time(chunk.2(x, n, force.number.of.groups = TRUE))
   user  system elapsed 
  5.360   0.300   5.663 

Note: Changing as.factor() to as.character() made my function twice as fast.

When you send bytes from a buffer with a normal TCP socket, the send function returns the number of bytes of the buffer that were sent. If it is a non-blocking socket or a non-blocking send then the number of bytes sent may be less than the size of the buffer. If it is a blocking socket or blocking send, then the number returned will match the size of the buffer but the call may block. With WebSockets, the data that is passed to the send method is always either sent as a whole "message" or not at all. Also, browser WebSocket implementations do not block on the send call.

But there are more important differences on the receiving side of things. When the receiver does a recv (or read) on a TCP socket, there is no guarantee that the number of bytes returned corresponds to a single send (or write) on the sender side. It might be the same, it may be less (or zero) and it might even be more (in which case bytes from multiple send/writes are received). With WebSockets, the recipient of a message is event-driven (you generally register a message handler routine), and the data in the event is always the entire message that the other side sent.

Note that you can do message based communication using TCP sockets, but you need some extra layer/encapsulation that is adding framing/message boundary data to the messages so that the original messages can be re-assembled from the pieces. In fact, WebSockets is built on normal TCP sockets and uses frame headers that contains the size of each frame and indicate which frames are part of a message. The WebSocket API re-assembles the TCP chunks of data into frames which are assembled into messages before invoking the message event handler once per message.

If someone still having this problem.Try to use instead of ovverriding

 public void OnActionExecuting(ActionExecutingContext context)
    {
        try
        {

            if (!HttpContext.Current.User.Identity.IsAuthenticated)
            {
                if (!HttpContext.Current.Response.IsRequestBeingRedirected)
                {

                    context.Result = new RedirectToRouteResult(
                new RouteValueDictionary {  { "controller", "Login" }, { "action", "Index" } });
                }
            }

        }
        catch (Exception ex)
        {
               new RouteValueDictionary { { "controller", "Login" }, { "action", "Index" } });
        }

    }

Simply move the declaration outside of the if block.

@{
string currentstore=HttpContext.Current.Request.ServerVariables["HTTP_HOST"];
string imgsrc="";
if (currentstore == "www.mydomain.com")
    {
    <link href="/path/to/my/stylesheets/styles1-print.css" rel="stylesheet" type="text/css" />
    imgsrc="/content/images/uploaded/store1_logo.jpg";
    }
else
    {
    <link href="/path/to/my/stylesheets/styles2-print.css" rel="stylesheet" type="text/css" />
    imgsrc="/content/images/uploaded/store2_logo.gif";
    }
}

<a href="@Url.RouteUrl("HomePage")" class="logo"><img  alt="" src="@imgsrc"></a>

You could make it a bit cleaner.

@{
string currentstore=HttpContext.Current.Request.ServerVariables["HTTP_HOST"];
string imgsrc="/content/images/uploaded/store2_logo.gif";
if (currentstore == "www.mydomain.com")
    {
    <link href="/path/to/my/stylesheets/styles1-print.css" rel="stylesheet" type="text/css" />
    imgsrc="/content/images/uploaded/store1_logo.jpg";
    }
else
    {
    <link href="/path/to/my/stylesheets/styles2-print.css" rel="stylesheet" type="text/css" />
    }
}

I found another relatively easy solution for your question.

As you can see from the FragmentPagerAdapter source code, the fragments managed by FragmentPagerAdapter store in the FragmentManager under the tag generated using:

String tag="android:switcher:" + viewId + ":" + index;

The viewId is the container.getId(), the container is your ViewPager instance. The index is the position of the fragment. Hence you can save the object id to the outState:

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    outState.putInt("viewpagerid" , mViewPager.getId() );
}

@Override
    protected void onCreate(Bundle savedInstanceState) {
    setContentView(R.layout.activity_main);
    if (savedInstanceState != null)
        viewpagerid=savedInstanceState.getInt("viewpagerid", -1 );  

    MyFragmentPagerAdapter titleAdapter = new MyFragmentPagerAdapter (getSupportFragmentManager() , this);        
    mViewPager = (ViewPager) findViewById(R.id.pager);
    if (viewpagerid != -1 ){
        mViewPager.setId(viewpagerid);
    }else{
        viewpagerid=mViewPager.getId();
    }
    mViewPager.setAdapter(titleAdapter);

If you want to communicate with this fragment, you can get if from FragmentManager, such as:

getSupportFragmentManager().findFragmentByTag("android:switcher:" + viewpagerid + ":0")

You could also try http://xmltoolbox.appspot.com/ it is an online xml formatter. You just paste your xml into a large text area field and press "format xml" then it pretty prints the xml in the text area so its easy to read or copy.

There is also a nice little filter feature that allows you to see all of a certain element.

Hope you will enjoy the tool

In case you had to deal with a lot of subfolders contatining subfolders and other recursive stuff. Small improvment of @Mike L'Angelo:

$mypath = "path_to_folder"
$myacl = Get-Acl $mypath
$myaclentry = "username","FullControl","Allow"
$myaccessrule = New-Object System.Security.AccessControl.FileSystemAccessRule($myaclentry)
$myacl.SetAccessRule($myaccessrule)
Get-ChildItem -Path "$mypath" -Recurse -Force | Set-Acl -AclObject $myacl -Verbose

Verbosity is optional in the last line

So you can use one stack to do a post order traversal.

private void PostOrderTraversal(Node pos) {
    Stack<Node> stack = new Stack<Node>();
    do {
        if (pos==null && (pos=stack.peek().right)==null) {
            for (visit(stack.peek()); stack.pop()==(stack.isEmpty()?null:stack.peek().right); visit(stack.peek())) {}
        } else if(pos!=null) {
            stack.push(pos);
            pos=pos.left;
        }
    } while (!stack.isEmpty());
}

Linux Mint 19. Helped for me:

sudo apt install tk-dev

P.S. Recompile python interpreter after package install.

If you want to make an empty data frame and add contents in a loop, the following may help:

# Number of students in class
student.count <- 36

# Gather data about the students
student.age <- sample(14:17, size = student.count, replace = TRUE)
student.gender <- sample(c('male', 'female'), size = student.count, replace = TRUE)
student.marks <- sample(46:97, size = student.count, replace = TRUE)

# Create empty data frame
student.data <- data.frame()

# Populate the data frame using a for loop
for (i in 1 : student.count) {
    # Get the row data
    age <- student.age[i]
    gender <- student.gender[i]
    marks <- student.marks[i]

    # Populate the row
    new.row <- data.frame(age = age, gender = gender, marks = marks)

    # Add the row
    student.data <- rbind(student.data, new.row)
}

# Print the data frame
student.data

Hope it helps :)

Add a Button and on click of the Button add this code:

Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND); 
sharingIntent.setType("text/plain");
String shareBody = "Here is the share content body";
sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Subject Here");
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
startActivity(Intent.createChooser(sharingIntent, "Share via"));

Useful links:

For basic sharing

For customization

This function could transform the data to percentages by columns

percent.colmns = function(base, columnas = 1:ncol(base), filas = 1:nrow(base)){
    base2 = base
    for(j in columnas){
        suma.c = sum(base[,j])
        for(i in filas){
            base2[i,j] = base[i,j]*100/suma.c
        }
    }
    return(base2)
}

Please Learn how Chart.js (version 2 here) works and do it for whatever attribute you want:

<canvas id="your-chart-id" height="your-height" width="your-width"></canvas>

2.Please suppose you have a javascript code that fills your chart first time (for example when page is loaded):

var ctx = document.getElementById('your-chart-id').getContext('2d');
var chartInstance = new Chart(ctx, {
    type: 'bar',
    data: {
        labels: your-lables-array,
        datasets: [{
            data: your-data-array,
            /*you can create random colors dynamically by ColorHash library [https://github.com/zenozeng/color-hash]*/
            backgroundColor: your-lables-array.map(function (item) {
                return colorHash.hex(item);
            })
        }]
    },
    options: {
        maintainAspectRatio: false,
        scales: {
            yAxes: [ { ticks: {beginAtZero: true} } ]
        },
        title: {display: true, fontSize: 16, text: 'chart title'},
        legend: {display: false}
    }
});

Please suppose you want to update fully your dataset. It is very simple. Please look at the above code and see how is the path from your chart variable to data and then follow the below path:

• select chartInstance var.
• Then select data node inside the chartInstance.
• Then select datasets node inside the data node.
  (note: As you can see, the datasets node is an array. so you have to specify which element of this array you want. here we have only one element in the datasets node. so we use datasets[0]
• So select datasets[0]
• Then select data node inside in the datasets[0].

This steps gives you chartInstance.data.datasets[0].data and you can set new data and update the chart:

chartInstance.data.datasets[0].data = NEW-your-data-array
//finally update chart var:
chartInstance.update();

If you want the date, given a month and a year, this seems about right:

public static DateTime GetLastDayOfMonth(this DateTime dateTime)
{
    return new DateTime(dateTime.Year, dateTime.Month, DateTime.DaysInMonth(dateTime.Year, dateTime.Month));
}

If it is in the same class it is fine to trust the method.

It is very common to do this. It is good practice to check null values in constructor's and method's arguments to make sure that nobody is passing null values into them (if it is not allowed). Then if you implement your methods in a way that they never set the "start" graph to null, don't check for nulls there.

It is also good practice to implement unit tests for your methods and make sure that they are correctly implemented, so you can trust them.

I hope this can help what you want.

monkey --pct-syskeys 0 for development boards

Without this argument, the app won't open on a development board without keys / display:

adb shell monkey --pct-syskeys 0 -p com.cirosantilli.android_cheat.textviewbold 1

and fails with error:

SYS_KEYS has no physical keys but with factor 2.0%

Tested on HiKey960, Android O AOSP.

Learned from: https://github.com/ARM-software/lisa/pull/408

Also asked at: monkey test : If the Android system doesnt has physical keys ,what are the parameters need to be includeded in the command

TypeScript 2.0 has the readonly modifier:

class MyClass {
    readonly myReadOnlyProperty = 1;

    myMethod() {
        console.log(this.myReadOnlyProperty);
        this.myReadOnlyProperty = 5; // error, readonly
    }
}

new MyClass().myReadOnlyProperty = 5; // error, readonly

It's not exactly a constant because it allows assignment in the constructor, but that's most likely not a big deal.

Alternative Solution

An alternative is to use the static keyword with readonly:

class MyClass {
    static readonly myReadOnlyProperty = 1;

    constructor() {
        MyClass.myReadOnlyProperty = 5; // error, readonly
    }

    myMethod() {
        console.log(MyClass.myReadOnlyProperty);
        MyClass.myReadOnlyProperty = 5; // error, readonly
    }
}

MyClass.myReadOnlyProperty = 5; // error, readonly

This has the benefit of not being assignable in the constructor and only existing in one place.

Maybe you could use:

select last_name+', '+first_name 
from user_mstr
where ',' + @user_id_list + ',' like '%,' + convert(nvarchar, user_id) + ',%'

For the point 2.

I see that no one has suggested to use document.elementFromPoint(x,y), to me it is the fastest way to test if an element is nested or hidden by another. You can pass the offsets of the targetted element to the function.

Here's PPK test page on elementFromPoint.

From MDN's documentation:

The elementFromPoint() method—available on both the Document and ShadowRoot objects—returns the topmost Element at the specified coordinates (relative to the viewport).

Your property file location is classpath:idm.properties

This is rather unusual, it means that idm.properties must be located either at the top level of WEB-INF/classes or at the top-level of one of the jars inside WEB-INF/lib. Usually it's good practice to either use a dedicated folder for properties or keep them close to the context files that use them.

So my suggestion is this: Is your properties file perhaps next to your context file? If so, it's not on the classpath (see this question: Is WEB-INF in the CLASSPATH?).

The classpath: prefix maps to a ClassPathResource, but you probably need a ServletContextResource, and you'll get that from a WebApplicationContext using the syntax without prefix:

<context:property-placeholder location="idm.properties" />

        string[,] arrValues = new string[5, 5];
        for (int i = 0; i < arrValues.GetLength(0); i++)
        {
            for (int j = 0; j < arrValues.GetLength(1); j++)
            {
                value++;
                arrValues[i, j] = value.ToString();
            }
        }
        ArrayPrinter.PrintToConsole(arrValues);
        Console.ReadLine();
    }
}

Yes you can handle with the catch operator like this and show alert as you want but firstly you have to import Rxjs for the same like this way

import {Observable} from 'rxjs/Rx';

return this.http.request(new Request(this.requestoptions))
            .map((res: Response) => {
                if (res) {
                    if (res.status === 201) {
                        return [{ status: res.status, json: res }]
                    }
                    else if (res.status === 200) {
                        return [{ status: res.status, json: res }]
                    }
                }
            }).catch((error: any) => {
                if (error.status === 500) {
                    return Observable.throw(new Error(error.status));
                }
                else if (error.status === 400) {
                    return Observable.throw(new Error(error.status));
                }
                else if (error.status === 409) {
                    return Observable.throw(new Error(error.status));
                }
                else if (error.status === 406) {
                    return Observable.throw(new Error(error.status));
                }
            });
    }

also you can handel error (with err block) that is throw by catch block while .map function,

like this -

...
.subscribe(res=>{....}
           err => {//handel here});

Update

as required for any status without checking particluar one you can try this: -

return this.http.request(new Request(this.requestoptions))
            .map((res: Response) => {
                if (res) {
                    if (res.status === 201) {
                        return [{ status: res.status, json: res }]
                    }
                    else if (res.status === 200) {
                        return [{ status: res.status, json: res }]
                    }
                }
            }).catch((error: any) => {
                if (error.status < 400 ||  error.status ===500) {
                    return Observable.throw(new Error(error.status));
                }
            })
            .subscribe(res => {...},
                       err => {console.log(err)} );

Yes, you can do this. The knack you need is the concept that there are two ways of getting tables out of the table server. One way is ..

FROM TABLE A

The other way is

FROM (SELECT col as name1, col2 as name2 FROM ...) B

Notice that the select clause and the parentheses around it are a table, a virtual table.

So, using your second code example (I am guessing at the columns you are hoping to retrieve here):

SELECT a.attr, b.id, b.trans, b.lang
FROM attribute a
JOIN (
 SELECT at.id AS id, at.translation AS trans, at.language AS lang, a.attribute
 FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)

Notice that your real table attribute is the first table in this join, and that this virtual table I've called b is the second table.

This technique comes in especially handy when the virtual table is a summary table of some kind. e.g.

SELECT a.attr, b.id, b.trans, b.lang, c.langcount
FROM attribute a
JOIN (
 SELECT at.id AS id, at.translation AS trans, at.language AS lang, at.attribute
 FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)
JOIN (
 SELECT count(*) AS langcount,  at.attribute
 FROM attributeTranslation at
 GROUP BY at.attribute
) c ON (a.id = c.attribute)

See how that goes? You've generated a virtual table c containing two columns, joined it to the other two, used one of the columns for the ON clause, and returned the other as a column in your result set.

I was facing the same problem. This way I was able to solved it. As CQM said, using Color.parseColor() is a good solution to this issue.

Here is the code I used:

this.Button_C.setTextColor(Color.parseColor(prefs.getString("color_prefs", String.valueOf(R.color.green))));

In this case my target was to change the Button's text color (Button_C) when I change the color selection from my Preferences (color_prefs).

A simple solution is to restart the service when the system stops it.

I found this very simple implementation of this method:

If you don't want the success message in the URL, then one option is to put it in the session (in the processForm method) and then check for it (and remove it) in the setupForm method.

Edited to add: if this is a pain to do manually, then you could write a subclass of RedirectView that adds a "message" attribute and wraps the process of inserting it into the session. Not sure, though, if there's an easy way to wrap getting the message back out of the session...

Honestly, I don't think there's an easy answer -- the nature of an HTTP redirect is that state isn't carried over; if you want to maintain state anyway, you're stuck with the various usual ways to maintain state in web applications: the session, a cookie, a querystring...

According to the doc about Run tests by node ids

since you have all node ids in foo.txt, just run

pytest `cat foo.txt | tr '\n' ' '`

this is same with below command (with file content in the question)

pytest tests_directory/foo.py::test_001 tests_directory/bar.py::test_some_other_test

We can use Carbon

 $time = '09:15 PM';
 $s=Carbon::parse($time);
 echo $military_time =$s->format('G:i');

Presumably you're passing the arguments in on the command line as follows:

php /path/to/wwwpublic/path/to/script.php arg1 arg2

... and then accessing them in the script thusly:

<?php
// $argv[0] is '/path/to/wwwpublic/path/to/script.php'
$argument1 = $argv[1];
$argument2 = $argv[2];
?>

What you need to be doing when passing arguments through HTTP (accessing the script over the web) is using the query string and access them through the $_GET superglobal:

Go to http://yourdomain.com/path/to/script.php?argument1=arg1&argument2=arg2

... and access:

<?php
$argument1 = $_GET['argument1'];
$argument2 = $_GET['argument2'];
?>

If you want the script to run regardless of where you call it from (command line or from the browser) you'll want something like the following:

EDIT: as pointed out by Cthulhu in the comments, the most direct way to test which environment you're executing in is to use the PHP_SAPI constant. I've updated the code accordingly:

<?php
if (PHP_SAPI === 'cli') {
    $argument1 = $argv[1];
    $argument2 = $argv[2];
}
else {
    $argument1 = $_GET['argument1'];
    $argument2 = $_GET['argument2'];
}
?>

A very good solution to this can be found here:

Here's a class that serves as a wrapper to a pyserial object. It allows you to read lines without 100% CPU. It does not contain any timeout logic. If a timeout occurs, self.s.read(i) returns an empty string and you might want to throw an exception to indicate the timeout.

It is also supposed to be fast according to the author:

The code below gives me 790 kB/sec while replacing the code with pyserial's readline method gives me just 170kB/sec.

class ReadLine:
    def __init__(self, s):
        self.buf = bytearray()
        self.s = s

    def readline(self):
        i = self.buf.find(b"\n")
        if i >= 0:
            r = self.buf[:i+1]
            self.buf = self.buf[i+1:]
            return r
        while True:
            i = max(1, min(2048, self.s.in_waiting))
            data = self.s.read(i)
            i = data.find(b"\n")
            if i >= 0:
                r = self.buf + data[:i+1]
                self.buf[0:] = data[i+1:]
                return r
            else:
                self.buf.extend(data)

ser = serial.Serial('COM7', 9600)
rl = ReadLine(ser)

while True:

    print(rl.readline())

Use vh attributes. It means viewport height and is a percentage. So height: 90vh would mean 90% of the viewport height. This works in most modern browsers.

Eg.

div {
  height: 90vh;
}

You can forego the rest of your silly 100% stuff on the body.

If you have a header you can also do some fun things like take it into account by using the calc function in CSS.

Eg.

div {
  height: calc(100vh - 50px);
}

This will give you 100% of the viewport height, minus 50px for your header.

@jellyfishtree it would be a better if you create one php file which includes all your js files from the directory and then only include this php file via a script tag. This has a better performance because the browser has to do less requests to the server. See this:

javascripts.php:

<?php
   //sets the content type to javascript 
   header('Content-type: text/javascript');

   // includes all js files of the directory
   foreach(glob("packages/*.js") as $file) {
      readfile($file);
   }
?>

index.php:

<script type="text/javascript" src="javascripts.php"></script>

That's it!
Have fun! :)

One more difference I found with respect to both is that it is fairly easy to connect to multiple databases with mongodb native driver while you have to use work arounds in mongoose which still have some drawbacks.

So if you wanna go for a multitenant application, go for mongodb native driver.

If you are not seeing the certificate under General->About->Certificate Trust Settings, then you probably do not have the ROOT CA installed. Very important -- needs to be a ROOT CA, not an intermediary CA.

if you try to change color of FAB by using app, there some problem. frame of button have different color, so what you must to do:

Georg Schölly's categories are very nice. However, for NSMutableArray, using NSUIntegers for the indices results in a crash when the array is empty. The correct code is:

@implementation NSMutableArray (Reverse)

    NSInteger j = [self count] - 1;
    while (i < j) {
        [self exchangeObjectAtIndex:i
                  withObjectAtIndex:j];

        i++;
        j--;
    }
}

An addition informative point that goes well with the answer by StompChicken above.

The fundamental difference between discriminative models and generative models is:

Discriminative models learn the (hard or soft) boundary between classes

Generative models model the distribution of individual classes

Edit:

A Generative model is the one that can generate data. It models both the features and the class (i.e. the complete data).

If we model P(x,y): I can use this probability distribution to generate data points - and hence all algorithms modeling P(x,y) are generative.

Eg. of generative models

• Naive Bayes models P(c) and P(d|c) - where c is the class and d is the feature vector.

  Also, P(c,d) = P(c) * P(d|c)

  Hence, Naive Bayes in some form models, P(c,d)

• Bayes Net

• Markov Nets

A discriminative model is the one that can only be used to discriminate/classify the data points. You only require to model P(y|x) in such cases, (i.e. probability of class given the feature vector).

Eg. of discriminative models:

• logistic regression

• Neural Networks

• Conditional random fields

In general, generative models need to model much more than the discriminative models and hence are sometimes not as effective. As a matter of fact, most (not sure if all) unsupervised learning algorithms like clustering etc can be called generative, since they model P(d) (and there are no classes:P)

PS: Part of the answer is taken from source

If you want formatted text, chain your commands with echo and use $0 to print the last field.

Example:

for i in {8..11}; do
   s1="$i"
   s2="str$i"
   s3="str with spaces $i"
   echo -n "$s1 $s2" | awk '{printf "|%3d|%6s",$1,$2}'
   echo -en "$s3" | awk '{printf "|%-19s|\n", $0}'
done

Prints:

|  8|  str8|str with spaces 8  |
|  9|  str9|str with spaces 9  |
| 10| str10|str with spaces 10 |
| 11| str11|str with spaces 11 |

For Python 3 you could try using quote instead of quote_plus:

import urllib.parse

print(urllib.parse.quote("http://www.sample.com/"))

Result:

http%3A%2F%2Fwww.sample.com%2F

Or:

from requests.utils import requote_uri
requote_uri("http://www.sample.com/?id=123 abc")

Result:

'https://www.sample.com/?id=123%20abc'

Your code works fine, except that the barplot is ordered from low to high. When you want to order the bars from high to low, you will have to add a -sign before value:

ggplot(corr.m, aes(x = reorder(miRNA, -value), y = value, fill = variable)) + 
  geom_bar(stat = "identity")

which gives:

Used data:

corr.m <- structure(list(miRNA = structure(c(5L, 2L, 3L, 6L, 1L, 4L), .Label = c("mmu-miR-139-5p", "mmu-miR-1983", "mmu-miR-301a-3p", "mmu-miR-5097", "mmu-miR-532-3p", "mmu-miR-96-5p"), class = "factor"),
                         variable = structure(c(1L, 1L, 1L, 1L, 1L, 1L), .Label = "pos", class = "factor"),
                         value = c(7L, 75L, 70L, 5L, 10L, 47L)),
                    class = "data.frame", row.names = c("1", "2", "3", "4", "5", "6"))

Currently there is no better way, however there may be a marginal improvement by moving SaveChanges inside for loop for probably 10 items.

int i = 0;

foreach (Employees item in sequence)
{
   t = new Employees ();
   t.Text = item.Text;
   dataContext.Employees.AddObject(t);   

   // this will add max 10 items together
   if((i % 10) == 0){
       dataContext.SaveChanges();
       // show some progress to user based on
       // value of i
   }
   i++;
}
dataContext.SaveChanges();

You can adjust 10 to be closer to better performance. It will not greatly improve speed but it will allow you to show some progress to user and make it more user friendly.

For me, adding the following block of code under <dependency management><dependencies> solved the problem.

I use numpy.fromiter to invert a 8-greyscale bitmap, yet no signs of side-effects

import Image
import numpy as np

im = Image.load('foo.jpg')
im = im.convert('L')

arr = np.fromiter(iter(im.getdata()), np.uint8)
arr.resize(im.height, im.width)

arr ^= 0xFF  # invert
inverted_im = Image.fromarray(arr, mode='L')
inverted_im.show()

You can use it to avoid defining global variables. This gives you an alternative for other designs. 3 designs presenting a solution to a problem.

A) Using functions without globals

def calculate_salary(employee, list_with_all_employees):
    x = _calculate_tax(list_with_all_employees)

    # some other calculations done to x
    pass

    y = # something 

    return y

def _calculate_tax(list_with_all_employees):
    return 1.23456 # return something

B) Using functions with globals

_list_with_all_employees = None

def calculate_salary(employee, list_with_all_employees):

    global _list_with_all_employees
    _list_with_all_employees = list_with_all_employees

    x = _calculate_tax()

    # some other calculations done to x
    pass

    y = # something

    return y

def _calculate_tax():
    return 1.23456 # return something based on the _list_with_all_employees var

C) Using functions inside another function

def calculate_salary(employee, list_with_all_employees):

    def _calculate_tax():
        return 1.23456 # return something based on the list_with_a--Lemployees var

    x = _calculate_tax()

    # some other calculations done to x
    pass
    y = # something 

    return y

Solution C) allows to use variables in the scope of the outer function without having the need to declare them in the inner function. Might be useful in some situations.

I've seen many variants of this problem. One of the main differences (that determines the difficulty) is whether there is some centralized attempt to have a "smart and efficient system" that would have load balancing (e.g., send more idle elevators to lobby in morning). If that is the case, the design will include a whole subsystem with really fun design.

A full design is obviously too much to present here and there are many altenatives. The breadth is also not clear. In an interview, they'll try to figure out how you would think. However, these are some of the things you would need:

1. Representation of the central controller (assuming there is one).

2. Representations of elevators

3. Representations of the interface units of the elevator (these may be different from elevator to elevator). Obviously also call buttons on every floor, etc.

4. Representations of the arrows or indicators on each floor (almost a "view" of the elevator model).

5. Representation of a human and cargo (may be important for factoring in maximal loads)

6. Representation of the building (in some cases, as certain floors may be blocked at times, etc.)

use $slice operator to limit array elements

GeoLocation.find({},{name: 1, geolocation:{$slice: -5}})
    .then((result) => {
      res.json(result);
    })
    .catch((err) => {
      res.status(500).json({ success: false, msg: `Something went wrong. ${err}` });
});

where geolocation is array of data, from that we get last 5 record.

This is what you can do:

SELECT * 
FROM yourTable
PIVOT (MAX(xCount) 
       FOR Week in ([1],[2],[3],[4],[5],[6],[7])) AS pvt

Why not try this?

html:

js:

$("p").text().trim();

1st is more efficient (and the best possible option) because val.ToLowerCase() creates a new object since Strings are immutable.

Before Android 4.4

What you are trying to do is simply not possible from an app (at least not on a non-rooted/non-modified device). The message "NFC tag type not supported" is displayed by the Android system (or more specifically the NFC system service) before and instead of dispatching the tag to your app. This means that the NFC system service filters MIFARE Classic tags and never notifies any app about them. Consequently, your app can't detect MIFARE Classic tags or circumvent that popup message.

On a rooted device, you may be able to bypass the message using either

1. Xposed to modify the behavior of the NFC service, or

2. the CSC (Consumer Software Customization) feature configuration files on the system partition (see /system/csc/. The NFC system service disables the popup and dispatches MIFARE Classic tags to apps if the CSC feature <CscFeature_NFC_EnableSecurityPromptPopup> is set to any value but "mifareclassic" or "all". For instance, you could use:

   <CscFeature_NFC_EnableSecurityPromptPopup>NONE</CscFeature_NFC_EnableSecurityPromptPopup>
   

   You could add this entry to, for instance, the file "/system/csc/others.xml" (within the section <FeatureSet> ... </FeatureSet> that already exists in that file).

Since, you asked for the Galaxy S6 (the question that you linked) as well: I have tested this method on the S4 when it came out. I have not verified if this still works in the latest firmware or on other devices (e.g. the S6).

Since Android 4.4

This is pure guessing, but according to this (link no longer available), it seems that some apps (e.g. NXP TagInfo) are capable of detecting MIFARE Classic tags on affected Samsung devices since Android 4.4. This might mean that foreground apps are capable of bypassing that popup using the reader-mode API (see NfcAdapter.enableReaderMode) possibly in combination with NfcAdapter.FLAG_READER_SKIP_NDEF_CHECK.

You can do this:

add-pssnapin Microsoft.Exchange.Management.PowerShell.E2010

and most of it will work (although MS support will tell you that doing this is not supported because it bypasses RBAC).

I've seen issues with some cmdlets (specifically enable/disable UMmailbox) not working with just the snapin loaded.

In Exchange 2010, they basically don't support using Powershell outside of the the implicit remoting environment of an actual EMS shell.

Often you need to put more into the manifest than what you get with the -e switch, and in that case, the syntax is:

jar -cvfm myJar.jar myManifest.txt myApp.class

Which reads: "create verbose jarFilename manifestFilename", followed by the files you want to include.

Note that the name of the manifest file you supply can be anything, as jar will automatically rename it and put it into the right place within the jar file.

Steps to manually configure DNS:

1. You can access Network and Sharing center by right clicking on the Network icon on the taskbar.

2. Now choose adapter settings from the side menu.

3. This will give you a list of the available network adapters in the system . From them right click on the adapter you are using to connect to the internet now and choose properties option.

4. In the networking tab choose ‘Internet Protocol Version 4 (TCP/IPv4)’.

5. Now you can see the properties dialogue box showing the properties of IPV4. Here you need to change some properties.

   Select ‘use the following DNS address’ option. Now fill the following fields as given here.

   Preferred DNS server: 208.67.222.222

   Alternate DNS server : 208.67.220.220

   This is an available Open DNS address. You may also use google DNS server addresses.

   After filling these fields. Check the ‘validate settings upon exit’ option. Now click OK.

You have to add this DNS server address in the router configuration also (by referring the router manual for more information).

Refer : for above method & alternative

If none of this works, then open command prompt(Run as Administrator) and run these:

ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew
NETSH winsock reset catalog
NETSH int ipv4 reset reset.log
NETSH int ipv6 reset reset.log
Exit

Hopefully that fixes it, if its still not fixed there is a chance that its a NIC related issue(driver update or h/w).

Also FYI, this has a thread on Microsoft community : Windows 10 - DNS Issue

DECLARE @ReseedBit BIT = 
    COALESCE((SELECT SUM(CONVERT(BIGINT, ic.last_value))
                FROM sys.identity_columns ic
                INNER JOIN sys.tables t ON ic.object_id = t.object_id), 0)

Caveats: This is intended for use in reference data population situations where a DB is being initialized with enum type definition tables, where the ID values in those tables must always start at 1. The first time the DB is being created (e.g. during SSDT-DB publishing) @Reseed must be 0, but when resetting the data i.e. removing the data and re-inserting it, then @Reseed must be 1. So this code is intended for use in a stored procedure for resetting the DB data, which can be called manually but is also called from the post-deployment script in the SSDT-DB project. In that way the reference data inserts are only defined in one place but aren't restricted to be used only in post-deployment during publishing, they are also available for subsequent use (to support dev and automated test etc.) by calling the stored procedure to reset the DB back to a known good state.

Something throws an exception of type std::bad_alloc, indicating that you ran out of memory. This exception is propagated through until main, where it "falls off" your program and causes the error message you see.

Since nobody here knows what "RectInvoice", "rectInvoiceVector", "vect", "im" and so on are, we cannot tell you what exactly causes the out-of-memory condition. You didn't even post your real code, because w h looks like a syntax error.

dataGridView1.Columns is probably of a length less than 5. Accessing dataGridView1.Columns[4] then will be outside the list.

why dont you do something like:

re = /^[a-z0-9 ]$/i;
var isValid = re.test(yourInput);

to check if your input contain any special char

If you are serious about maintaining interoperability with other JVM languages (e.g. Java) then the best option is to write Java enums. Those work transparently from both Scala and Java code, which is more than can be said for scala.Enumeration or case objects. Let's not have a new enumerations library for every new hobby project on GitHub, if it can be avoided!

You can create a dict and pass this as the data param to the dataframe constructor:

In [235]:

df = pd.DataFrame({'Gene':s.index, 'count':s.values})
df
Out[235]:
   Gene  count
0  Ezh2      2
1  Hmgb      7
2  Irf1      1

Alternatively you can create a df from the series, you need to call reset_index as the index will be used and then rename the columns:

In [237]:

df = pd.DataFrame(s).reset_index()
df.columns = ['Gene', 'count']
df
Out[237]:
   Gene  count
0  Ezh2      2
1  Hmgb      7
2  Irf1      1

Object doesn't support this property or method.

Think of it like if anything after the dot is called on an object. It's like a chain.

An object is a class instance. A class instance supports some properties defined in that class type definition. It exposes whatever intelli-sense in VBE tells you (there are some hidden members but it's not related to this). So after each dot . you get intelli-sense (that white dropdown) trying to help you pick the correct action.

(you can start either way - front to back or back to front, once you understand how this works you'll be able to identify where the problem occurs)

Type this much anywhere in your code area

Dim a As Worksheets
a.

you get help from VBE, it's a little dropdown called Intelli-sense

It lists all available actions that particular object exposes to any user. You can't see the .Selection member of the Worksheets() class. That's what the error tells you exactly.

Object doesn't support this property or method.

If you look at the example on MSDN

Worksheets("GRA").Activate
iAreaCount = Selection.Areas.Count

It activates the sheet first then calls the Selection... it's not connected together because Selection is not a member of Worksheets() class. Simply, you can't prefix the Selection

What about

Sub DisplayColumnCount()
    Dim iAreaCount As Integer
    Dim i As Integer

    Worksheets("GRA").Activate
    iAreaCount = Selection.Areas.Count

    If iAreaCount <= 1 Then
        MsgBox "The selection contains " & Selection.Columns.Count & " columns."
    Else
        For i = 1 To iAreaCount
        MsgBox "Area " & i & " of the selection contains " & _
        Selection.Areas(i).Columns.Count & " columns."
        Next i
    End If
End Sub

You are creating an array of three elements and assigning all three to the same thing, which is itself an array of three elements (three Doubles).

When you do the modifications you are modifying the floats in the internal array.

Wow, that was easier than I thought:

git checkout -b newbranch v1.0

You can take the first string, replace all the @ with vs using str_replace, then explode on vs or vice versa.

My "disappeared" folder was libraries/fof.

If I deleted it, then ran an update, it wouldn't show up.

cd libaries
svn up

(nothing happens).

But updating with the actual name:

svn update fof

did the trick and it was updated. So I exploded my (manually tar-archived) working copy over it and recommitted. Easiest solution.

try changing the native_transport_protocol to port 9160 (if it is set to anything other than 9160; it might be pointing to 9042). Check your logs and see on which port cassandra is listening for CQL clients?

For CUDA version:

nvcc --version

Or use,

nvidia-smi

For cuDNN version:

For Linux:

Use following to find path for cuDNN:

$ whereis cuda
cuda: /usr/local/cuda

Then use this to get version from header file,

$ cat /usr/local/cuda/include/cudnn.h | grep CUDNN_MAJOR -A 2

For Windows,

Use following to find path for cuDNN:

C:\>where cudnn*
C:\Program Files\cuDNN7\cuda\bin\cudnn64_7.dll

Then use this to dump version from header file,

type "%PROGRAMFILES%\cuDNN7\cuda\include\cudnn.h" | findstr CUDNN_MAJOR

If you're getting two different versions for CUDA on Windows - Different CUDA versions shown by nvcc and NVIDIA-smi

In Bootstrap 3, .form-control (the class you give your inputs) has a width of 100%, which allows you to wrap them into col-lg-X divs for arrangement. Example from the docs:

<div class="row">
  <div class="col-lg-2">
    <input type="text" class="form-control" placeholder=".col-lg-2">
  </div>
  <div class="col-lg-3">
    <input type="text" class="form-control" placeholder=".col-lg-3">
  </div>
  <div class="col-lg-4">
    <input type="text" class="form-control" placeholder=".col-lg-4">
  </div>
</div>

See under Column sizing.

It's a bit different than in Bootstrap 2.3.2, but you get used to it quickly.

Use StringBuilder:

StringBuilder sb = new StringBuilder(str);
sb.setCharAt(i - 1, 'k');
str = sb.toString();

So am I assuming correctly that uid is a Unique Identifier (Guid)? Is this just an example of a possible scenario or are you really trying to find a guid that matches an array of strings?

If this is true you may want to really rethink this whole approach, this seems like a really bad idea. You should probably be trying to match a Guid to a Guid

Guid id = new Guid(uid);
var query = from xx in table
            where xx.uid == id
            select xx;

I honestly can't imagine a scenario where matching a string array using "contains" to the contents of a Guid would be a good idea. For one thing, Contains() will not guarantee the order of numbers in the Guid so you could potentially match multiple items. Not to mention comparing guids this way would be way slower than just doing it directly.

You should use

$('#dropdownid').val('selectedvalue');

Here's an example:

$('#dropdownid').val('selectedvalue');

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id='dropdownid'>
    <option value=''>- Please choose -</option>
    <option value='1'>1</option>
    <option value='2'>2</option>
    <option value='selectedvalue'>There we go!</option>
    <option value='3'>3</option>
    <option value='4'>4</option>
    <option value='5'>5</option>
</select>

Enumerable.SequenceEqual(FirstList.OrderBy(fElement => fElement), 
                         SecondList.OrderBy(sElement => sElement))

append strings with add function

str1 = "Hello"
str2 = " World"
str3 = str.__add__(str2)
print(str3)

Output

Hello World

Just add the'order_by' clause to your code and modify it to look just like the one below.

$this->db->order_by('name', 'asc');
$result = $this->db->get($table);

There you go.

You should be able to use Windows "UNC" paths with robocopy. For example:

robocopy \\myServer\myFolder\myFile.txt \\myOtherServer\myOtherFolder

Robocopy has the ability to recover from certain types of network hiccups automatically.

The question is tagged SQL Server 2000 but for the benefit of people developing on the latest version I'll address that first.

SQL Server 2014

In addition to the methods of adding constraint based indexes discussed below SQL Server 2014 also allows non unique indexes to be specified directly with inline syntax on table variable declarations.

Example syntax for that is below.

/*SQL Server 2014+ compatible inline index syntax*/
DECLARE @T TABLE (
C1 INT INDEX IX1 CLUSTERED, /*Single column indexes can be declared next to the column*/
C2 INT INDEX IX2 NONCLUSTERED,
       INDEX IX3 NONCLUSTERED(C1,C2) /*Example composite index*/
);

Filtered indexes and indexes with included columns can not currently be declared with this syntax however SQL Server 2016 relaxes this a bit further. From CTP 3.1 it is now possible to declare filtered indexes for table variables. By RTM it may be the case that included columns are also allowed but the current position is that they "will likely not make it into SQL16 due to resource constraints"

/*SQL Server 2016 allows filtered indexes*/
DECLARE @T TABLE
(
c1 INT NULL INDEX ix UNIQUE WHERE c1 IS NOT NULL /*Unique ignoring nulls*/
)

SQL Server 2000 - 2012

Can I create a index on Name?

Short answer: Yes.

DECLARE @TEMPTABLE TABLE (
  [ID]   [INT] NOT NULL PRIMARY KEY,
  [Name] [NVARCHAR] (255) COLLATE DATABASE_DEFAULT NULL,
  UNIQUE NONCLUSTERED ([Name], [ID]) 
  ) 

A more detailed answer is below.

Traditional tables in SQL Server can either have a clustered index or are structured as heaps.

Clustered indexes can either be declared as unique to disallow duplicate key values or default to non unique. If not unique then SQL Server silently adds a uniqueifier to any duplicate keys to make them unique.

Non clustered indexes can also be explicitly declared as unique. Otherwise for the non unique case SQL Server adds the row locator (clustered index key or RID for a heap) to all index keys (not just duplicates) this again ensures they are unique.

In SQL Server 2000 - 2012 indexes on table variables can only be created implicitly by creating a UNIQUE or PRIMARY KEY constraint. The difference between these constraint types are that the primary key must be on non nullable column(s). The columns participating in a unique constraint may be nullable. (though SQL Server's implementation of unique constraints in the presence of NULLs is not per that specified in the SQL Standard). Also a table can only have one primary key but multiple unique constraints.

Both of these logical constraints are physically implemented with a unique index. If not explicitly specified otherwise the PRIMARY KEY will become the clustered index and unique constraints non clustered but this behavior can be overridden by specifying CLUSTERED or NONCLUSTERED explicitly with the constraint declaration (Example syntax)

DECLARE @T TABLE
(
A INT NULL UNIQUE CLUSTERED,
B INT NOT NULL PRIMARY KEY NONCLUSTERED
)

As a result of the above the following indexes can be implicitly created on table variables in SQL Server 2000 - 2012.

+-------------------------------------+-------------------------------------+
|             Index Type              | Can be created on a table variable? |
+-------------------------------------+-------------------------------------+
| Unique Clustered Index              | Yes                                 |
| Nonunique Clustered Index           |                                     |
| Unique NCI on a heap                | Yes                                 |
| Non Unique NCI on a heap            |                                     |
| Unique NCI on a clustered index     | Yes                                 |
| Non Unique NCI on a clustered index | Yes                                 |
+-------------------------------------+-------------------------------------+

The last one requires a bit of explanation. In the table variable definition at the beginning of this answer the non unique non clustered index on Name is simulated by a unique index on Name,Id (recall that SQL Server would silently add the clustered index key to the non unique NCI key anyway).

A non unique clustered index can also be achieved by manually adding an IDENTITY column to act as a uniqueifier.

DECLARE @T TABLE
(
A INT NULL,
B INT NULL,
C INT NULL,
Uniqueifier INT NOT NULL IDENTITY(1,1),
UNIQUE CLUSTERED (A,Uniqueifier)
)

But this is not an accurate simulation of how a non unique clustered index would normally actually be implemented in SQL Server as this adds the "Uniqueifier" to all rows. Not just those that require it.

You are correct: calling finish() will only exit the current activity, not the entire application. however, there is a workaround for this:

Every time you start an Activity, start it using startActivityForResult(...). When you want to close the entire app, you can do something like this:

setResult(RESULT_CLOSE_ALL);
finish();

Then define every activity's onActivityResult(...) callback so when an activity returns with the RESULT_CLOSE_ALL value, it also calls finish():

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    switch(resultCode)
    {
    case RESULT_CLOSE_ALL:
        setResult(RESULT_CLOSE_ALL);
        finish();
    }
    super.onActivityResult(requestCode, resultCode, data);
}

This will cause a cascade effect closing all activities.

Also, I support CommonsWare in his suggestion: store the password in a variable so that it will be destroyed when the application is closed.

you can use git commit -am "[comment]" // best solution or git add . && git commit -m "[comment]"

I'm quite late to the party, but one approach is to use a static inner class to unwrap values:

import com.fasterxml.jackson.annotation.JsonCreator;
import com.fasterxml.jackson.annotation.JsonProperty;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;

class Scratch {
    private final String aString;
    private final String bString;
    private final String cString;
    private final static String jsonString;

    static {
        jsonString = "{\n" +
                "  \"wrap\" : {\n" +
                "    \"A\": \"foo\",\n" +
                "    \"B\": \"bar\",\n" +
                "    \"C\": \"baz\"\n" +
                "  }\n" +
                "}";
    }

    @JsonCreator
    Scratch(@JsonProperty("A") String aString,
            @JsonProperty("B") String bString,
            @JsonProperty("C") String cString) {
        this.aString = aString;
        this.bString = bString;
        this.cString = cString;
    }

    @Override
    public String toString() {
        return "Scratch{" +
                "aString='" + aString + '\'' +
                ", bString='" + bString + '\'' +
                ", cString='" + cString + '\'' +
                '}';
    }

    public static class JsonDeserializer {
        private final Scratch scratch;

        @JsonCreator
        public JsonDeserializer(@JsonProperty("wrap") Scratch scratch) {
            this.scratch = scratch;
        }

        public Scratch getScratch() {
            return scratch;
        }
    }

    public static void main(String[] args) throws JsonProcessingException {
        ObjectMapper objectMapper = new ObjectMapper();
        Scratch scratch = objectMapper.readValue(jsonString, Scratch.JsonDeserializer.class).getScratch();
        System.out.println(scratch.toString());
    }
}

However, it's probably easier to use objectMapper.configure(SerializationConfig.Feature.UNWRAP_ROOT_VALUE, true); in conjunction with @JsonRootName("aName"), as pointed out by pb2q

The jsfiddle link to where i tried out your query http://jsfiddle.net/A8Dnv/1/ its working fine @Imrul as mentioned you are using C# on server side and you dont mind that either: http://msdn.microsoft.com/en-us/library/system.text.regularexpressions.regex.escape.aspx

You CAN use UTF-8 in the POST request, all you need is to specify the charset in your request.

You should use this request:

curl -X POST -H "Content-Type: application/x-www-form-urlencoded; charset=utf-8" --data-ascii "content=derinhält&date=asdf" http://myserverurl.com/api/v1/somemethod

That will work but you will have to be careful not to overload your server because it will create a new process every time you call this function which will run in background. If only one concurrent call at the same time then this workaround will do the job.

If not then I would advice to run a message queue like for instance beanstalkd/gearman/amazon sqs.

Recently when working on a web app for a client, I noticed that any click events added to a non-anchor element didn't work on the iPad or iPhone. All desktop and other mobile devices worked fine - but as the Apple products are the most popular mobile devices, it was important to get it fixed.

Turns out that any non-anchor element assigned a click handler in jQuery must either have an onClick attribute (can be empty like below):

onClick=""

OR

The element css needs to have the following declaration:

cursor:pointer

Strange, but that's what it took to get things working again!

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

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

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

The first one using str.charAt should be faster.

If you dig inside the source code of String class, we can see that charAt is implemented as follows:

public char charAt(int index) {
    if ((index < 0) || (index >= count)) {
        throw new StringIndexOutOfBoundsException(index);
    }
    return value[index + offset];
}

Here, all it does is index an array and return the value.

Now, if we see the implementation of toCharArray, we will find the below:

public char[] toCharArray() {
    char result[] = new char[count];
    getChars(0, count, result, 0);
    return result;
}

public void getChars(int srcBegin, int srcEnd, char dst[], int dstBegin) {
    if (srcBegin < 0) {
        throw new StringIndexOutOfBoundsException(srcBegin);
    }
    if (srcEnd > count) {
        throw new StringIndexOutOfBoundsException(srcEnd);
    }
    if (srcBegin > srcEnd) {
        throw new StringIndexOutOfBoundsException(srcEnd - srcBegin);
    }
    System.arraycopy(value, offset + srcBegin, dst, dstBegin,
         srcEnd - srcBegin);
}

As you see, it is doing a System.arraycopy which is definitely going to be a tad slower than not doing it.

From the jQuery :input selector page:

Because :input is a jQuery extension and not part of the CSS specification, queries using :input cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. To achieve the best performance when using :input to select elements, first select the elements using a pure CSS selector, then use .filter(":input").

This is the best choice.

$('#new_user_form *').filter(':input').each(function(){
    //your code here
});

I think the best answer in 2017 is to use the javax.json APIs. Use javax.json.JsonBuilderFactory to create your json objects, then write the objects out using javax.json.JsonWriterFactory. Very nice builder/writer combination.

Pure/vanilla JS solution (working example here)

// All elements with data-company="Microsoft" below "Companies"
let a = document.querySelectorAll("[data-group='Companies'] [data-company='Microsoft']"); 

// All elements with data-company!="Microsoft" below "Companies"
let b = document.querySelectorAll("[data-group='Companies'] :not([data-company='Microsoft'])"); 

In querySelectorAll you must use valid CSS selector (currently Level3)

SPEED TEST (2018.06.29) for jQuery and Pure JS: test was performed on MacOs High Sierra 10.13.3 on Chrome 67.0.3396.99 (64-bit), Safari 11.0.3 (13604.5.6), Firefox 59.0.2 (64-bit). Below screenshot shows results for fastest browser (Safari):

PureJS was faster than jQuery about 12% on Chrome, 21% on Firefox and 25% on Safari. Interestingly speed for Chrome was 18.9M operation per second, Firefox 26M, Safari 160.9M (!).

So winner is PureJS and fastest browser is Safari (more than 8x faster than Chrome!)

string.split("=", 2);

As String.split(java.lang.String regex, int limit) explains:

The array returned by this method contains each substring of this string that is terminated by another substring that matches the given expression or is terminated by the end of the string. The substrings in the array are in the order in which they occur in this string. If the expression does not match any part of the input then the resulting array has just one element, namely this string.

The limit parameter controls the number of times the pattern is applied and therefore affects the length of the resulting array. If the limit n is greater than zero then the pattern will be applied at most n - 1 times, the array's length will be no greater than n, and the array's last entry will contain all input beyond the last matched delimiter.

The string boo:and:foo, for example, yields the following results with these parameters:

Regex Limit    Result
:     2        { "boo", "and:foo" }
:     5        { "boo", "and", "foo" }
:    -2        { "boo", "and", "foo" }
o     5        { "b", "", ":and:f", "", "" }
o    -2        { "b", "", ":and:f", "", "" }
o     0        { "b", "", ":and:f" }

This is one way to do it:

SQL> set serveroutput on
SQL> CREATE OR REPLACE TYPE MyType AS VARRAY(200) OF VARCHAR2(50);
  2  /

Type created

SQL> CREATE OR REPLACE PROCEDURE testing (t_in MyType) IS
  2  BEGIN
  3    FOR i IN 1..t_in.count LOOP
  4      dbms_output.put_line(t_in(i));
  5    END LOOP;
  6  END;
  7  /

Procedure created

SQL> DECLARE
  2    v_t MyType;
  3  BEGIN
  4    v_t := MyType();
  5    v_t.EXTEND(10);
  6    v_t(1) := 'this is a test';
  7    v_t(2) := 'A second test line';
  8    testing(v_t);
  9  END;
 10  /

this is a test
A second test line

To expand on my comment to @dcp's answer, here's how you could implement the solution proposed there if you wanted to use an associative array:

SQL> CREATE OR REPLACE PACKAGE p IS
  2    TYPE p_type IS TABLE OF VARCHAR2(50) INDEX BY BINARY_INTEGER;
  3  
  4    PROCEDURE pp (inp p_type);
  5  END p;
  6  /

Package created
SQL> CREATE OR REPLACE PACKAGE BODY p IS
  2    PROCEDURE pp (inp p_type) IS
  3    BEGIN
  4      FOR i IN 1..inp.count LOOP
  5        dbms_output.put_line(inp(i));
  6      END LOOP;
  7    END pp;
  8  END p;
  9  /

Package body created
SQL> DECLARE
  2    v_t p.p_type;
  3  BEGIN
  4    v_t(1) := 'this is a test of p';
  5    v_t(2) := 'A second test line for p';
  6    p.pp(v_t);
  7  END;
  8  /

this is a test of p
A second test line for p

PL/SQL procedure successfully completed

This trades creating a standalone Oracle TYPE (which cannot be an associative array) with requiring the definition of a package that can be seen by all in order that the TYPE it defines there can be used by all.

You're missing comma (,) inbetween:

>>> ((1,2) (2,3))
Traceback (most recent call last):

TypeError: 'tuple' object is not callable

Put comma:

>>> ((1,2), (2,3))
((1, 2), (2, 3))

To get the number of seconds from the Javascript epoch use:

date = new Date();
milliseconds = date.getTime();
seconds = milliseconds / 1000;

Include the jQuery file first:

That error message also appeared into my VM. First of all, I tried to disable the option "Enable VT-x/AMD-V" (you can find it opening the settings of your VM: Settings->System->Acceleration), there was a warning saying that "Invalid settings detected (you accept the changes and the box was selected again).

Then I read this posts and I tried to enable the Virtualiation Techniuqe (used when you want to enable various VM in your computer (by default is set as Disabled because you don't need that property working.

Build.Version is the place go to for this data. Here is a code snippet for how to format it.

public String getAndroidVersion() {
    String release = Build.VERSION.RELEASE;
    int sdkVersion = Build.VERSION.SDK_INT;
    return "Android SDK: " + sdkVersion + " (" + release +")";
}

Looks like this "Android SDK: 19 (4.4.4)"

Edit

This answer is now deprecated. See the answer by apsillers.

Since this is for a Chrome extension, you might as well use the standard DOM event - DOMSubtreeModified. See the support for this event across browsers. It has been supported in Chrome since 1.0.

$("#someDiv").bind("DOMSubtreeModified", function() {
    alert("tree changed");
});

See a working example here.

Java 8 Comparator interface has a reversed method : https://docs.oracle.com/javase/8/docs/api/java/util/Comparator.html#reversed--

Try like below:

DELETE posts.*,projects.* 
FROM posts
INNER JOIN projects ON projects.project_id = posts.project_id
WHERE projects.client_id = :client_id;

html, body{ 
  width:100%;
}

This tells the html to be 100% wide. But 100% refers to the whole browser window width, so no more than that.

You may want to set a min width instead.

html, body{ 
  min-width:100%;
}

So it will be 100% as a minimum, bot more if needed.

select t2.* 
from t1 join t2 on t2.url='site.com/path/%' + cast(t1.id as varchar)  + '%/more' 
where t1.id > 9000

Using concat like suggested is even better though

Wrap all the children inside of another LinearLayout with wrap_content for both the width and the height as well as the vertical orientation.

System.Text.ASCIIEncoding.Unicode.GetByteCount(yourString);

Or

System.Text.ASCIIEncoding.ASCII.GetByteCount(yourString);

you should not do JSON.stringify(data) while sending through AJAX like below.

This is NOT correct code:

function callAjax(url, data) {
    $.ajax({
        url: url,
        type: "POST",
        data: JSON.stringify(data),
        success: function(d) {
            alert("successs "+ JSON.stringify(d));
        }
    });
}   

The correct code is:

function callAjax(url, data) {
    $.ajax({
        url: url,
        type: "POST",
        data: data,
        success: function(d) {
            alert("successs "+ JSON.stringify(d));
        }
    });
}

For others who landed in this error and it's not 100% related to the OP question, please check that you are passing the value and it is not null in case of spring-boot: @Value annotation.

This answer may come a bit late but I have found an acceptable solution. My approach is a bit similar to @Mani one but I think mine is a bit more easy to understand.

Putting it into global hook and into the component itself are not ideal, global hook checks every request so you will need to write a lot of conditions to check if it should be 404 and window.location.href in the component creation is too late as the request has gone into the component already and then you take it out.

What I did is to have a dedicated url for 404 pages and have a path * that for everything that not found.

{ path: '/:locale/404', name: 'notFound', component: () => import('pages/Error404.vue') },
{ path: '/:locale/*', 
  beforeEnter (to) {
    window.location = `/${to.params.locale}/404`
  }
}

You can ignore the :locale as my site is using i18n so that I can make sure the 404 page is using the right language.

On the side note, I want to make sure my 404 page is returning httpheader 404 status code instead of 200 when page is not found. The solution above would just send you to a 404 page but you are still getting 200 status code. To do this, I have my nginx rule to return 404 status code on location /:locale/404

server {
    listen                      80;
    server_name                 localhost;

    error_page  404 /index.html;
    location ~ ^/.*/404$ {
      root   /usr/share/nginx/html;
      internal;
    }

    location / {
      root   /usr/share/nginx/html;
      index  index.html index.htm;
      try_files $uri $uri/ @rewrites;
    }

    location @rewrites {
      rewrite ^(.+)$ /index.html last;
    }

    location = /50x.html {
      root   /usr/share/nginx/html;
    }
}

While the previous answers may work in a fashion, I think that using BehaviorSubject is the correct way if you want to continue using observables.

Example:

    this.store.subscribe(
        (data:any) => {
            myService.myBehaviorSubject.next(data)
        }
    )

In the Service:

let myBehaviorSubject = new BehaviorSubjet(value);

In component.ts:

this.myService.myBehaviorSubject.subscribe(data => this.myData = data)

I hope this helps!

From official documentation :

To enable Google to crawl your app content and allow users to enter your app from search results, you must add intent filters for the relevant activities in your app manifest. These intent filters allow deep linking to the content in any of your activities. For example, the user might click on a deep link to view a page within a shopping app that describes a product offering that the user is searching for.

Using this link Enabling Deep Links for App Content you'll see how to use it.

And using this Test Your App Indexing Implementation how to test it.

The following XML snippet shows how you might specify an intent filter in your manifest for deep linking.

<activity
    android:name="com.example.android.GizmosActivity"
    android:label="@string/title_gizmos" >
    <intent-filter android:label="@string/filter_title_viewgizmos">
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <!-- Accepts URIs that begin with "http://www.example.com/gizmos” -->
        <data android:scheme="http"
              android:host="www.example.com"
              android:pathPrefix="/gizmos" />
        <!-- note that the leading "/" is required for pathPrefix-->
        <!-- Accepts URIs that begin with "example://gizmos” -->
        <data android:scheme="example"
              android:host="gizmos" />

    </intent-filter>
</activity>

To test via Android Debug Bridge

$ adb shell am start
        -W -a android.intent.action.VIEW
        -d <URI> <PACKAGE>

$ adb shell am start
        -W -a android.intent.action.VIEW
        -d "example://gizmos" com.example.android

I moved my project from "standard" hosting to Azure and get the same error when I try to open page with url-rewrite. I.e. rule is :

<add key="/iPod-eBook-Creator.html" value="/Product/ProductDetail?PRODUCT_UID=IPOD_EBOOK_CREATOR" />

try to open my_site/iPod-eBook-Creator.html and get this error (page my_site/Product/ProductDetail?PRODUCT_UID=IPOD_EBOOK_CREATOR can be opened without any problem).

I checked the fully site - never used .. to "level up"

The issue, I believe, is that the Json action result is intended to take an object (your model) and create an HTTP response with content as the JSON-formatted data from your model object.

What you are passing to the controller's Json method, though, is a JSON-formatted string object, so it is "serializing" the string object to JSON, which is why the content of the HTTP response is surrounded by double-quotes (I'm assuming that is the problem).

I think you can look into using the Content action result as an alternative to the Json action result, since you essentially already have the raw content for the HTTP response available.

return this.Content(returntext, "application/json");
// not sure off-hand if you should also specify "charset=utf-8" here, 
//  or if that is done automatically

Another alternative would be to deserialize the JSON result from the service into an object and then pass that object to the controller's Json method, but the disadvantage there is that you would be de-serializing and then re-serializing the data, which may be unnecessary for your purposes.

To remove disabled attribute use,

 $("#elementID").removeAttr('disabled');

and to add disabled attribute use,

$("#elementID").prop("disabled", true);

Enjoy :)

You can do something like this:

// show loading image
$('#loader_img').show();

// main image loaded ?
$('#main_img').on('load', function(){
  // hide/remove the loading image
  $('#loader_img').hide();
});

You assign load event to the image which fires when image has finished loading. Before that, you can show your loader image.

Core jQuery doesn't have anything special for touch events, but you can easily build your own using the following events

• touchstart
• touchmove
• touchend
• touchcancel

For example, the touchmove

document.addEventListener('touchmove', function(e) {
    e.preventDefault();
    var touch = e.touches[0];
    alert(touch.pageX + " - " + touch.pageY);
}, false);

This works in most WebKit based browsers (incl. Android).

Here is some good documentation.

Either approach works. But if you have a long list of optional parameters make a default constructor and then have your set function return a reference to this. Then chain the settors.

class Thingy2
{
public:
    enum Color{red,gree,blue};
    Thingy2();

    Thingy2 & color(Color);
    Color color()const;

    Thingy2 & length(double);
    double length()const;
    Thingy2 & width(double);
    double width()const;
    Thingy2 & height(double);
    double height()const;

    Thingy2 & rotationX(double);
    double rotationX()const;
    Thingy2 & rotatationY(double);
    double rotatationY()const;
    Thingy2 & rotationZ(double);
    double rotationZ()const;
}

main()
{
    // gets default rotations
    Thingy2 * foo=new Thingy2().color(ret)
        .length(1).width(4).height(9)
    // gets default color and sizes
    Thingy2 * bar=new Thingy2()
        .rotationX(0.0).rotationY(PI),rotationZ(0.5*PI);
    // everything specified.
    Thingy2 * thing=new Thingy2().color(ret)
        .length(1).width(4).height(9)
        .rotationX(0.0).rotationY(PI),rotationZ(0.5*PI);
}

Now when constructing the objects you can pick an choose which properties to override and which ones you have set are explicitly named. Much more readable :)

Also, you no longer have to remember the order of the arguments to the constructor.

Use ResponseEntity instead of ResponseBody. This way you have access to the response headers and you can set the appropiate content type. According to the Spring docs:

The HttpEntity is similar to @RequestBody and @ResponseBody. Besides getting access to the request and response body, HttpEntity (and the response-specific subclass ResponseEntity) also allows access to the request and response headers

The code will look like:

@RequestMapping(method=RequestMethod.GET, value="/fooBar")
public ResponseEntity<String> fooBar2() {
    String json = "jsonResponse";
    HttpHeaders responseHeaders = new HttpHeaders();
    responseHeaders.setContentType(MediaType.APPLICATION_JSON);
    return new ResponseEntity<String>(json, responseHeaders, HttpStatus.CREATED);
}

If it says the API key is listed as a header, more than likely you need to set it in the headers option of your http request. Normally something like this :

headers: {'Authorization': '[your API key]'}

Here is an example from another Question

$http({method: 'GET', url: '[the-target-url]', headers: {
  'Authorization': '[your-api-key]'}
});

Edit : Just saw you wanted to store the response in a variable. In this case I would probably just use AJAX. Something like this :

$.ajax({ 
   type : "GET", 
   url : "[the-target-url]", 
   beforeSend: function(xhr){xhr.setRequestHeader('Authorization', '[your-api-key]');},
   success : function(result) { 
       //set your variable to the result 
   }, 
   error : function(result) { 
     //handle the error 
   } 
 }); 

I got this from this question and I'm at work so I can't test it at the moment but looks solid

Edit 2: Pretty sure you should be able to use this line :

headers: {'Authorization': '[your API key]'},

instead of the beforeSend line in the first edit. This may be simpler for you

You could use very easily reflection to list all properties, methods and values.

For Gecko based browsers you can use the .toSource() method:

var data = new Object();
data["firstname"] = "John";
data["lastname"] = "Smith";
data["age"] = 21;

alert(data.toSource()); //Will return "({firstname:"John", lastname:"Smith", age:21})"

But since you use Firebug, why not just use console.log?

If you have problems with numbers (say 1, 2, 10, 12 which will be sorted 1, 10, 12, 2) you can use LINQ:

var arr = arr.OrderBy(x=>x).ToArray();

The traditional way to deal with asynchronous calls in JavaScript has been with callbacks. Say we had to make three calls to the server, one after the other, to set up our application. With callbacks, the code might look something like the following (assuming a xhrGET function to make the server call):

// Fetch some server configuration
    xhrGET('/api/server-config', function(config) {
        // Fetch the user information, if he's logged in
        xhrGET('/api/' + config.USER_END_POINT, function(user) {
            // Fetch the items for the user
            xhrGET('/api/' + user.id + '/items', function(items) {
                // Actually display the items here
            });
        });
    });

In this example, we first fetch the server configuration. Then based on that, we fetch information about the current user, and then finally get the list of items for the current user. Each xhrGET call takes a callback function that is executed when the server responds.

Now of course the more levels of nesting we have, the harder the code is to read, debug, maintain, upgrade, and basically work with. This is generally known as callback hell. Also, if we needed to handle errors, we need to possibly pass in another function to each xhrGET call to tell it what it needs to do in case of an error. If we wanted to have just one common error handler, that is not possible.

The Promise API was designed to solve this nesting problem and the problem of error handling.

The Promise API proposes the following:

1. Each asynchronous task will return a promise object.
2. Each promise object will have a then function that can take two arguments, a success handler and an error handler.
3. The success or the error handler in the then function will be called only once, after the asynchronous task finishes.
4. The then function will also return a promise, to allow chaining multiple calls.
5. Each handler (success or error) can return a value, which will be passed to the next function as an argument, in the chain of promises.
6. If a handler returns a promise (makes another asynchronous request), then the next handler (success or error) will be called only after that request is finished.

So the previous example code might translate to something like the following, using promises and the $http service(in AngularJs):

$http.get('/api/server-config').then(
    function(configResponse) {
        return $http.get('/api/' + configResponse.data.USER_END_POINT);
    }
).then(
    function(userResponse) {
        return $http.get('/api/' + userResponse.data.id + '/items');
    }
).then(
    function(itemResponse) {
        // Display items here
    }, 
    function(error) {
        // Common error handling
    }
);

Propagating Success and Error

Chaining promises is a very powerful technique that allows us to accomplish a lot of functionality, like having a service make a server call, do some postprocessing of the data, and then return the processed data to the controller. But when we work with promise chains, there are a few things we need to keep in mind.

Consider the following hypothetical promise chain with three promises, P1, P2, and P3. Each promise has a success handler and an error handler, so S1 and E1 for P1, S2 and E2 for P2, and S3 and E3 for P3:

xhrCall()
  .then(S1, E1) //P1
  .then(S2, E2) //P2
  .then(S3, E3) //P3

In the normal flow of things, where there are no errors, the application would flow through S1, S2, and finally, S3. But in real life, things are never that smooth. P1 might encounter an error, or P2 might encounter an error, triggering E1 or E2.

Consider the following cases:

• We receive a successful response from the server in P1, but the data returned is not correct, or there is no data available on the server (think empty array). In such a case, for the next promise P2, it should trigger the error handler E2.

• We receive an error for promise P2, triggering E2. But inside the handler, we have data from the cache, ensuring that the application can load as normal. In that case, we might want to ensure that after E2, S3 is called.

So each time we write a success or an error handler, we need to make a call—given our current function, is this promise a success or a failure for the next handler in the promise chain?

If we want to trigger the success handler for the next promise in the chain, we can just return a value from the success or the error handler

If, on the other hand, we want to trigger the error handler for the next promise in the chain, we can do that using a deferred object and calling its reject() method

Now What is deferred object?

Deferred objects in jQuery represents a unit of work that will be completed later, typically asynchronously. Once the unit of work completes, the deferred object can be set to resolved or failed.

A deferred object contains a promise object. Via the promise object you can specify what is to happen when the unit of work completes. You do so by setting callback functions on the promise object.

Deferred objects in Jquery : https://api.jquery.com/jquery.deferred/

Deferred objects in AngularJs : https://docs.angularjs.org/api/ng/service/$q

Go to Anaconda Naviagator, find spyder,click settings in the top right corner of the spyder app.click update tab

Update t 
SET 
       t.Column1=100
FROM 
       myTableA t 
LEFT JOIN 
       myTableB t2 
ON

Replace myTableA with your table name and replace Column1 with your column name.

After this simply LEFT JOIN to tableB. t in this case is just an alias for myTableA. t2 is an alias for your joined table, in my example that is myTableB. If you don't like using t or t2 use any alias name you prefer - it doesn't matter - I just happen to like using those.

You, or most likely your sysadmin, will need to login as root and run the chown command: http://www.computerhope.com/unix/uchown.htm

Through this command you will become the owner of the file.

Or, you can be a member of a group that owns this file and then you can use chmod.

But, talk with your sysadmin.

The following signature will do:

Spring Data JPA supports a large number of keywords to build a query. IN and AND are among them.

You can access the version through a URL, the web GUI, and the ReST API.

Via a URL

An HTML page displaying the version can be displayed in a browser at https://your-gitlab-url/help. The version is displayed only if you are signed in.

Via a menu in the web GUI

If you do not care to type this URL, you can also access the same HTML page from a menu in the GitLab web GUI:

In GitLab 11 and later

1. Log in to GitLab
2. Click on the drop down menu in the upper right. Select Help.
3. The GitLab version appears at the top of the page

In earlier versions, like GitLab 9

1. Log in to GitLab
2. Click on the drop down menu in the upper left. Select Help.
3. And then the version appears at the top of the page

Via the ReST API

Log in as any user, select the user icon in the upper right of the screen. Select Settings > Access Tokens. Create a personal access token and copy it to your clipboard.

In a Linux shell, use curl to access the GitLab version:

curl --header "PRIVATE-TOKEN: personal-access-token" your-gitlab-url/api/v4/version

It depends on how and when you want to redirect the user to another page.

If you want to instantly redirect a user to another page without him seeing anything of a site in between, you should use the PHP header redirect method.

If you have a Javascript and some action of the user has to result in him entering another page, that is when you should use window.location.

The meta tag refresh is often used on download sites whenever you see these "Your download should start automatically" messages. You can let the user load a page, wait for a certain amount of time, then redirect him (e.g. to a to-be-downloaded file) without Javascript.

I do it in simpler way - first install jquery by npm in console: npm install jquery -S and then in component file I just write: let $ = require('.../jquery.min.js') and it works! Here full example from some my code:

import { Component, Input, ElementRef, OnInit } from '@angular/core';
let $ = require('../../../../../node_modules/jquery/dist/jquery.min.js');

@Component({
    selector: 'departments-connections-graph',
    templateUrl: './departmentsConnectionsGraph.template.html',
})

export class DepartmentsConnectionsGraph implements OnInit {
    rootNode : any;
    container: any;

    constructor(rootNode: ElementRef) {
      this.rootNode = rootNode; 
    }

    ngOnInit() {
      this.container = $(this.rootNode.nativeElement).find('.departments-connections-graph')[0];
      console.log({ container : this.container});
      ...
    }
}

In teplate I have for instance:

<div class="departments-connections-graph">something...</div>

EDIT

Alternatively instead of using:

let $ = require('../../../../../node_modules/jquery/dist/jquery.min.js');

use

declare var $: any;

and in your index.html put:

<script src="assets/js/jquery-2.1.1.js"></script>

This will initialize jquery only once globaly - this is important for instance for use modal windows in bootstrap...

Here you go:

public static byte[] ConvertToByteArray(string str, Encoding encoding)
{
    return encoding.GetBytes(str);
}

public static String ToBinary(Byte[] data)
{
    return string.Join(" ", data.Select(byt => Convert.ToString(byt, 2).PadLeft(8, '0')));
}

// Use any sort of encoding you like. 
var binaryString = ToBinary(ConvertToByteArray("Welcome, World!", Encoding.ASCII));

From site PostgreSQL, of date 02/04/2016 (https://jdbc.postgresql.org/download.html):

"This is the current version of the driver. Unless you have unusual requirements (running old applications or JVMs), this is the driver you should be using. It supports Postgresql 7.2 or newer and requires a 1.6 or newer JVM. It contains support for SSL and the javax.sql package. If you are using the 1.6 then you should use the JDBC4 version. If you are using 1.7 then you should use the JDBC41 version. If you are using 1.8 then you should use the JDBC42 versionIf you are using a java version older than 1.6 then you will need to use a JDBC3 version of the driver, which will by necessity not be current"

In my case, I was able to resolve the issue by doing the following:

I changed my code from this:

var r2 = db.Instances.Where(x => x.Player1 == inputViewModel.InstanceList.FirstOrDefault().Player2 && x.Player2 == inputViewModel.InstanceList.FirstOrDefault().Player1).ToList();

To this:

var p1 = inputViewModel.InstanceList.FirstOrDefault().Player1;
var p2 = inputViewModel.InstanceList.FirstOrDefault().Player2;
var r1 = db.Instances.Where(x => x.Player1 == p1 && x.Player2 == p2).ToList();

Since the glyphicons image is a sprite, you really can't do that: fundamentally what you want is to limit the size of the background, but there's no way to specify how big the background is. Either you cut out the icon you want, size it down and use it, or use something like the input field prepend/append option (http://twitter.github.io/bootstrap/base-css.html#forms and then search for prepended inputs).

I guess you're wondering why C or C++ lets you manipulate an object pointer like a number, but you can't manipulate an object reference in Java the same way.

Object references in Java aren't like pointers in C or C++... Pointers basically are integers and you can manipulate them like any other int. References are intentionally a more concrete abstraction and cannot be manipulated the way pointers can.

And please, whatever you do, configure the listings package to use fixed-width font (as in your example; you'll find the option in the documentation). Default setting uses proportional font typeset on a grid, which is, IMHO, incredibly ugly and unreadable, as can be seen from the other answers with pictures. I am personally very irritated when I must read some code typeset in a proportional font.

Try setting fixed-width font with this:

\lstset{basicstyle=\ttfamily}

DECLARE @col NVARCHAR(MAX);
SELECT @col= COALESCE(@col, '') + ',' + COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS WHERE  Table_name = 'MxLocations';
SELECT @col;

Python is a dynamically typed language, which means that you cannot define the type of the variable as you do in C or C++:

type variable = value

or

type variable(value)

In Python, you use coercing if you change types, or the init functions (constructors) of the types to declare a variable of a type:

my_set = set([1,2,3])
type my_set

will give you <type 'set'> for an answer.

If you have a list, do this:

my_list = [1,2,3]
my_set = set(my_list)

You need to use the target selector.

Here is a fiddle with another example: http://jsfiddle.net/YYPKM/3/

Just access the element and append it to the value.

<input
     type="button" 
     onclick="document.getElementById('myTextArea').value += '•'" 
     value="Add •">

For the sake of keeping things simple, I haven't written unobtrusive JS. For a production system you should.

Also it needs to be a UTF8 character.

Browsers generally submit forms using the encoding they received the page in. Serve your page as UTF-8 if you want UTF-8 data submitted back.

You have to define the compare first. There are 3 ways to do that:

1. use class
2. use struct (which is same as class)
3. use lambda function.

It's easy to use class/struct because easy to declare just write this line of code above your executing code

struct compare{
  public:
  bool operator()(Node& a,Node& b) // overloading both operators 
  {
      return a.w < b.w: // if you want increasing order;(i.e increasing for minPQ)
      return a.w > b.w // if you want reverse of default order;(i.e decreasing for minPQ)
   }
};

Calling code:

priority_queue<Node,vector<Node>,compare> pq;
