Start with looking up the z-value for your desired confidence interval from a look-up table. The confidence interval is then mean +/- z*sigma, where sigma is the estimated standard deviation of your sample mean, given by sigma = s / sqrt(n), where s is the standard deviation computed from your sample data and n is your sample size.

Let's fit the model:

> library(ISwR)
> fit <- lm(metabolic.rate ~ body.weight, rmr)
> summary(fit)

Call:
lm(formula = metabolic.rate ~ body.weight, data = rmr)

Residuals:
    Min      1Q  Median      3Q     Max 
-245.74 -113.99  -32.05  104.96  484.81 

Coefficients:
            Estimate Std. Error t value Pr(>|t|)    
(Intercept) 811.2267    76.9755  10.539 2.29e-13 ***
body.weight   7.0595     0.9776   7.221 7.03e-09 ***
---
Signif. codes:  0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ 0.1 ‘ ’ 1 

Residual standard error: 157.9 on 42 degrees of freedom
Multiple R-squared: 0.5539, Adjusted R-squared: 0.5433 
F-statistic: 52.15 on 1 and 42 DF,  p-value: 7.025e-09 

The 95% confidence interval for the slope is the estimated coefficient (7.0595) ± two standard errors (0.9776).

This can be computed using confint:

> confint(fit, 'body.weight', level=0.95)
               2.5 % 97.5 %
body.weight 5.086656 9.0324

If you need to you can also add an image that contains the arrow as part of the background.

Load the multicol package, like this \usepackage{multicol}. Then use:

\begin{multicols}{2}
Column 1
\columnbreak
Column 2
\end{multicols}

If you omit the \columnbreak, the columns will balance automatically.

you can directly edit your file with

sed -i '/^#/ d'

If you want also delete comment lines that start with some whitespace use

sed -i '/^\s*#/ d'

Usually, you want to keep the first line of your script, if it is a sha-bang, so sed should not delete lines starting with #!. also it should delete lines, that just contain only a hash but no text. put it all together:

sed -i '/^\s*\(#[^!].*\|#$\)/d'

To be conform with all sed variants you need to add a backup extension to the -i option:

sed -i.bak '/^\s*#/ d' $file
rm -Rf $file.bak

Seems the SMTP as internet standard uses only reliable Transport protocol. RFC821 has TCP, NCP, NITS as examples!

• In C++11, use std::stoi as:

   std::string s = "10";
   int i = std::stoi(s);
  

  Note that std::stoi will throw exception of type std::invalid_argument if the conversion cannot be performed, or std::out_of_range if the conversion results in overflow(i.e when the string value is too big for int type). You can use std::stol or std:stoll though in case int seems too small for the input string.

• In C++03/98, any of the following can be used:

   std::string s = "10";
   int i;
  
   //approach one
   std::istringstream(s) >> i; //i is 10 after this
  
   //approach two
   sscanf(s.c_str(), "%d", &i); //i is 10 after this
  

Note that the above two approaches would fail for input s = "10jh". They will return 10 instead of notifying error. So the safe and robust approach is to write your own function that parses the input string, and verify each character to check if it is digit or not, and then work accordingly. Here is one robust implemtation (untested though):

int to_int(char const *s)
{
     if ( s == NULL || *s == '\0' )
        throw std::invalid_argument("null or empty string argument");

     bool negate = (s[0] == '-');
     if ( *s == '+' || *s == '-' ) 
         ++s;

     if ( *s == '\0')
        throw std::invalid_argument("sign character only.");

     int result = 0;
     while(*s)
     {
          if ( *s < '0' || *s > '9' )
            throw std::invalid_argument("invalid input string");
          result = result * 10  - (*s - '0');  //assume negative number
          ++s;
     }
     return negate ? result : -result; //-result is positive!
} 

This solution is slightly modified version of my another solution.

Missing the 'implements' keyword in the impl classes might also be the issue

This occurred for me when my computer's disk space was full. Delete some files & empty the trash to fix.

If you want to use echo "a\tb" in a script, you run the script as:

# sh -e myscript.sh

Alternatively, you can give to myscript.sh the execution permission, and then run the script.

# chmod +x myscript.sh
# ./myscript.sh

I came across System.Runtime.InteropServices.COMException while opening a project solution. Sometimes user doesn't have enough priveleges to run some COM Methods. I ran Visual Studio as Administrator and the exception was gone.

Once you find the term you need to remove it from String under process so that it won't resolve the same again, use indexOf() and substring() , you don't need to do contains check length times

If you really need to specify all the .jar files dynamically you could use shell scripts, or Apache Ant. There's a commons project called Commons Launcher which basically lets you specify your startup script as an ant build file (if you see what I mean).

Then, you can specify something like:

<path id="base.class.path">
    <pathelement path="${resources.dir}"/>
    <fileset dir="${extensions.dir}" includes="*.jar" />
    <fileset dir="${lib.dir}" includes="*.jar"/>
</path>

In your launch build file, which will launch your application with the correct classpath.

Solution With Less XAML and More C#

If you define the ListView in XAML:

<ListView x:Name="listView"/>

Then you can add columns and populate it in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Add columns
    var gridView = new GridView();
    this.listView.View = gridView;
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Id", DisplayMemberBinding = new Binding("Id") });
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Name", DisplayMemberBinding = new Binding("Name") });

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

Solution With More XAML and less C#

However, it's easier to define the columns in XAML (inside the ListView definition):

<ListView x:Name="listView">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Id" DisplayMemberBinding="{Binding Id}"/>
            <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
        </GridView>
    </ListView.View>
</ListView>

And then just populate the list in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

MyItem Definition

MyItem is defined like this:

public class MyItem
{
    public int Id { get; set; }

    public string Name { get; set; }
}

To list all local groups which have users assigned to them, use this command:

cut -d: -f1 /etc/group | sort

No, you can't do this using Javascript alone. Client-side Javascript cannot read the contents of a directory the way I think you're asking about.

However, if you're able to add an index page to (or configure your web server to show an index page for) the images directory and you're serving the Javascript from the same server then you could make an AJAX call to fetch the index and then parse it.

i.e.

1) Enable indexes in Apache for the relevant directory on yoursite.com:

http://www.cyberciti.biz/faq/enabling-apache-file-directory-indexing/

2) Then fetch / parse it with jQuery. You'll have to work out how best to scrape the page and there's almost certainly a more efficient way of fetching the entire list, but an example:

$.ajax({
  url: "http://yoursite.com/images/",
  success: function(data){
     $(data).find("td > a").each(function(){
        // will loop through 
        alert("Found a file: " + $(this).attr("href"));
     });
  }
});

Addition to @MarkR answer - one thing to note would be that many PHP frameworks with ORMs would not recognize or use advanced DB setup (foreign keys, cascading delete, unique constraints), and this may result in unexpected behaviour.

For example if you delete a record using ORM, and your DELETE CASCADE will delete records in related tables, ORM's attempt to delete these related records (often automatic) will result in error.

I can replace all query parameters with this single line: $location.search({});
Easy to understand and easy way to clear them out.

You can also use conda to install packages: See http://conda.pydata.org

conda install nltk

The best way to use conda is to download Miniconda, but you can also try

pip install conda
conda init
conda install nltk

One thing that should be considered is licensing.

Notepad++ is free (as in speech and as in beer) for perpetual use, released under the GPL license, whereas Sublime Text 2 requires a license.

To quote the Sublime Text 2 website:

..a license must be purchased for continued use. There is currently no enforced time limit for the evaluation.

The same is now true of Sublime Text 3, and a paid upgrade will be needed for future versions.

Upgrade Policy A license is valid for Sublime Text 3, and includes all point updates, as well as access to prior versions (e.g., Sublime Text 2). Future major versions, such as Sublime Text 4, will be a paid upgrade.

This licensing requirement is still correct as of Dec 2019.

Just add another way , in normal mode , type ctrl+v then G, select the rest, then D, I don't think it is effective , you should do like @Ed Guiness, head -n 20 > filename in linux.

If you are using SQL Server 2012 or later, you can use:

SELECT FORMAT(MyDate, 'MMMM dd yyyy')

You can view the documentation for more information on the format.

WebElement selectgender = driver.findElement(By.id("gender"));
selectgender.sendKeys("Male");

graph-fs

Install

npm i graph-fs

Use

const {Node} = require("graph-fs");
const directory = new Node("/path/to/directory");

directory.clear(); // <--

I am sure that you probably wanted the answer that @GSerg gave. There is also a worksheet function called rows that will give you the number of rows.

So, if you have a named data range called Data that has 7 rows, then =ROWS(Data) will show 7 in that cell.

This is how I get a random number between 2 int's!

func randomNumber(MIN: Int, MAX: Int)-> Int{
    var list : [Int] = []
    for i in MIN...MAX {
        list.append(i)
    }
    return list[Int(arc4random_uniform(UInt32(list.count)))]
}

usage:

print("My Random Number is: \(randomNumber(MIN:-10,MAX:10))")

Expanding on Dominic Tancredi's awesome answer, I've rolled this into a bash package and stand-alone script. If you are already using the "Back Package Manager" called bpkg you can install the script by running:

bpkg install -g brock/node-reinstall

Or you can have a look at the script on Github at brock/node-reinstall. The script allows you to re-install node using nvm or nave, and to specify a node version as your default.

You can get your answer fairly easily for the iPhone5 along with other smartphones on the media feature database for mobile devices:

http://pieroxy.net/blog/2012/10/18/media_features_of_the_most_common_devices.html

You can even get your own device values on the test page on the same website.

(Disclaimer: This is my website)

A jQuery solution:

$("#frame1").ready( function() {

  $("#frame1").contents().scrollTop( $("#frame1").contents().scrollTop() + 10 );

});

The two common approaches are to submit the form to an invisible iframe, or to use a Flash control such as YUI Uploader. You could also use Java instead of Flash, but this has a narrower install base.

(Shame about the layout table in the first example)

The essential way is

• read(),
• data = data.replace() as often as you need and then
• write().

If you read and write the whole data at once or in smaller parts is up to you. You should make it depend on the expected file size.

read() can be replaced with the iteration over the file object.

Try (maybe as root)

lsof -i -P

and grep the output for the port you are looking for.

For example to check for port 80 do

lsof -i -P | grep :80

Building on Joan-Diego Rodriguez's routine with Jordi's approach and some of Jacek Kotowski's code - This function converts any table name for the active workbook into a usable address for SQL queries.

Note to MikeL: Addition of "[#All]" includes headings avoiding problems you reported.

Function getAddress(byVal sTableName as String) as String 

    With Range(sTableName & "[#All]")
        getAddress= "[" & .Parent.Name & "$" & .Address(False, False) & "]"
    End With

End Function

IE can set username and password proxies, so maybe setting it there and import does work

reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyEnable /t REG_DWORD /d 1
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyServer /t REG_SZ /d name:port
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyUser /t REG_SZ /d username
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyPass /t REG_SZ /d password
netsh winhttp import proxy source=ie

there is also a sneak way with pandas:

pd.to_timedelta(x) - pd.to_timedelta(y)

In my search for a creating a v4 uuid, I came first to this page, then found this on http://php.net/manual/en/function.com-create-guid.php

function guidv4()
{
    if (function_exists('com_create_guid') === true)
        return trim(com_create_guid(), '{}');

    $data = openssl_random_pseudo_bytes(16);
    $data[6] = chr(ord($data[6]) & 0x0f | 0x40); // set version to 0100
    $data[8] = chr(ord($data[8]) & 0x3f | 0x80); // set bits 6-7 to 10
    return vsprintf('%s%s-%s-%s-%s-%s%s%s', str_split(bin2hex($data), 4));
}

credit: pavel.volyntsev

Edit: to clarify, this function will always give you a v4 uuid (PHP >= 5.3.0).

When the com_create_guid function is available (usually only on Windows), it will use that and strip the curly braces.

If not present (Linux), it will fall back on this strong random openssl_random_pseudo_bytes function, it will then uses vsprintf to format it into v4 uuid.

The method you are looking for is jQuery's .text() and you can used it in the following fashion:

$('#a_tbnotesverbergen').text('text here');

In python3, __init__.py is no longer necessary. If the current directory of the console is the directory where the python script is located, everything works fine with

import user

However, this won't work if called from a different directory, which does not contain user.py.
In that case, use

from . import user

This works even if you want to import the whole file instead of just a class from there.

// Change the way body-parser is used
const bodyParser = require('body-parser');

var rawBodySaver = function (req, res, buf, encoding) {
  if (buf && buf.length) {
    req.rawBody = buf.toString(encoding || 'utf8');
  }
}
app.use(bodyParser.json({ verify: rawBodySaver, extended: true }));




// Now we can access raw-body any where in out application as follows
request.rawBody;

You need to follow the steps described in Troubleshooting: Connecting to SQL Server When System Administrators Are Locked Out and add your own Windows user as a member of sysadmin:

• shutdown MSSQL$EXPRESS service (or whatever the name of your SQL Express service is)
• start add the -m and -f startup parameters (or you can start sqlservr.exe -c -sEXPRESS -m -f from console)
• connect to DAC: sqlcmd -E -A -S .\EXPRESS or from SSMS use admin:.\EXPRESS
• run create login [machinename\username] from windows to create your Windows login in SQL
• run sp_addsrvrolemember 'machinename\username', 'sysadmin'; to make urself sysadmin member
• restart service w/o the -m -f

You have to read the API carefully for this methods. Sometimes you can get confused very easily.

It is either:

if (B.class.isInstance(view))

API says: Determines if the specified Object (the parameter) is assignment-compatible with the object represented by this Class (The class object you are calling the method at)

or:

if (B.class.isAssignableFrom(view.getClass()))

API says: Determines if the class or interface represented by this Class object is either the same as, or is a superclass or superinterface of, the class or interface represented by the specified Class parameter

or (without reflection and the recommended one):

if (view instanceof B)

dynamically typed language helps to quickly prototype algorithm concepts without the overhead of about thinking what variable types need to be used (which is a necessity in statically typed language).

It can work well as you guess

python testMyCase.py MyCase.testItIsHot

And there is another way to just test testItIsHot:

    suite = unittest.TestSuite()
    suite.addTest(MyCase("testItIsHot"))
    runner = unittest.TextTestRunner()
    runner.run(suite)

if (basename($_SERVER['PHP_SELF']) == basename(__FILE__)) { die('Access denied'); };

Of course in PHP7.2

sudo apt-get install php7.2-dev

user: root

password: [blank]

XAMPP v3.2.2

The second result set have only one column but it should have 3 columns for it to be contented to the first result set

(columns must match when you use UNION)

Try to add ID as first column and PartOf_LOC_id to your result set, so you can do the UNION.

;
WITH    q AS ( SELECT   ID ,
                    Location ,
                    PartOf_LOC_id
           FROM     tblLocation t
           WHERE    t.ID = 1 -- 1 represents an example
           UNION ALL
           SELECT   t.ID ,
                    parent.Location + '>' + t.Location ,
                    t.PartOf_LOC_id
           FROM     tblLocation t
                    INNER JOIN q parent ON parent.ID = t.LOC_PartOf_ID
         )
SELECT  *
FROM    q

As the recent developed Web Applications are using JavaScript, jQuery, AngularJS, ReactJS etc there is a possibility that to retrieve an attribute of an element through Selenium you have to induce WebDriverWait to synchronize the WebDriver instance with the lagging Web Client i.e. the Web Browser before trying to retrieve any of the attributes.

Some examples:

• Python:

  • To retrieve any attribute form a visible element (e.g. <h1> tag) you need to use the expected_conditions as visibility_of_element_located(locator) as follows:

    attribute_value = WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.ID, "org"))).get_attribute("attribute_name")
    

  • To retrieve any attribute form an interactive element (e.g. <input> tag) you need to use the expected_conditions as element_to_be_clickable(locator) as follows:

    attribute_value = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.ID, "org"))).get_attribute("attribute_name")
    

HTML Attributes

Below is a list of some attributes often used in HTML

Note: A complete list of all attributes for each HTML element, is listed in: HTML Attribute Reference

For Android Studio 3.4.1

Simply open the gradle tab (can be located on the right) and right-click on the parent in the list (should be called "Android"), then select "Refresh dependencies".

This should resolve your issue.

If you are looking for a brand new pull from another branch like from local to master you can follow this.

git commit -m "Initial Commit"
git add .
git pull --rebase git_url
git push origin master

One other easy way of doing it would be as follows (if you have a simple NetBeans project and not using maven for example).

1. In Eclipse, Go to File -> New -> Java Project
2. Give a name for your project and click finish to create your project
3. When the project is created find the source folder in NetBeans project, drag and drop all the source files from the NetBeans project to 'src' folder of your new created project in eclipse.
4. Move the java source files to respective package (if required)
5. Now you should be able to run your NetBeans project in Eclipse.

\r is used to point to the start of a line and can replace the text from there, e.g.

main()
{
printf("\nab");
printf("\bsi");
printf("\rha");
}

Produces this output:

hai

\n is for new line.

For example, if you have a users entity you want to store, with fields (firstname, lastname , email) and you want autogenerated id, you do this.

@Entity(tableName = "users")
data class Users(
   @PrimaryKey(autoGenerate = true)
   val id: Long,
   val firstname: String,
   val lastname: String,
   val email: String
)

Room will then autogenerate and auto-increment the id field.

Assuming key can only be a string but value can be anything try this

public static Dictionary<TKey, TValue> MyMethod<TKey, TValue>(object obj)
{
    if (obj is Dictionary<TKey, TValue> stringDictionary)
    {
        return stringDictionary;
    }

    if (obj is IDictionary baseDictionary)
    {
        var dictionary = new Dictionary<TKey, TValue>();
        foreach (DictionaryEntry keyValue in baseDictionary)
        {
            if (!(keyValue.Value is TValue))
            {
                // value is not TKey. perhaps throw an exception
                return null;
            }
            if (!(keyValue.Key is TKey))
            {
                // value is not TValue. perhaps throw an exception
                return null;
            }

            dictionary.Add((TKey)keyValue.Key, (TValue)keyValue.Value);
        }
        return dictionary;
    }
    // object is not a dictionary. perhaps throw an exception
    return null;
}

I had let this go for a good while but revisited it later. Since this question is viewed regularly. This is eventually what I ended up using that worked for me.

define("DOC_ROOT","/path/to/html");
//username and password of account
$username = trim($values["email"]);
$password = trim($values["password"]);

//set the directory for the cookie using defined document root var
$path = DOC_ROOT."/ctemp";
//build a unique path with every request to store. the info per user with custom func. I used this function to build unique paths based on member ID, that was for my use case. It can be a regular dir.
//$path = build_unique_path($path); // this was for my use case

//login form action url
$url="https://www.example.com/login/action"; 
$postinfo = "email=".$username."&password=".$password;

$cookie_file_path = $path."/cookie.txt";

$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_NOBODY, false);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);

curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path);
//set the cookie the site has for certain features, this is optional
curl_setopt($ch, CURLOPT_COOKIE, "cookiename=0");
curl_setopt($ch, CURLOPT_USERAGENT,
    "Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_REFERER, $_SERVER['REQUEST_URI']);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postinfo);
curl_exec($ch);

//page with the content I want to grab
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/page/");
//do stuff with the info with DomDocument() etc
$html = curl_exec($ch);
curl_close($ch);

Update: This code was never meant to be a copy and paste. It was to show how I used it for my specific use case. You should adapt it to your code as needed. Such as directories, vars etc

Instead of "returning true", you can also use the "noop" or null utility (as referred in the POSIX specs) : and just "do nothing". You'll save a few letters. :)

#!/usr/bin/env bash
set -e
man nonexistentghing || :
echo "It's ok.."

I tried:

python -m pip install --upgrade pip

And After that, it works fine for me in Windows 10.

PHP exec("php script.php") can do it.

From the Manual:

If a program is started with this function, in order for it to continue running in the background, the output of the program must be redirected to a file or another output stream. Failing to do so will cause PHP to hang until the execution of the program ends.

So if you redirect the output to a log file (what is a good idea anyways), your calling script will not hang and your email script will run in bg.

   |
   | Default: ~/.m2/repository
  <localRepository>/path/to/local/repo</localRepository>
  -->

  <!-- interactiveMode
   | This will determine whether maven prompts you when it needs input. If set
   | to false, maven will use a sensible default value, perhaps based on some
   | other setting, for the parameter in question.
   |
   | Default: true
  <interactiveMode>true</interactiveMode>
  -->

  <!-- offline
   | Determines whether maven should attempt to connect to the network when
   | executing a build. This will have an effect on artifact downloads,
   | artifact deployment, and others.
   |
   | Default: false
  <offline>false</offline>
  -->

  <!-- pluginGroups
   | This is a list of additional group identifiers that will be searched when
   | resolving plugins by their prefix, i.e. when invoking a command line like
   | "mvn prefix:goal". Maven will automatically add the group identifiers
   | "org.apache.maven.plugins" and "org.codehaus.mojo" if these are not

Proxies:

  <!-- proxies
   | This is a list of proxies which can be used on this machine to connect to
   | the network. Unless otherwise specified (by system property or command-
   | line switch), the first proxy specification in this list marked as active
   | will be used.

Servers:

   | This is a list of authentication profiles, keyed by the server-id used
   | within the system. Authentication profiles can be used whenever maven must
   | make a connection to a remote server.
   |-->
  <servers>
    <!-- server
     | Specifies the authentication information to use when connecting to a
     | particular server, identified by a unique name within the system
     | (referred to by the 'id' attribute below).
     |
     | NOTE: You should either specify username/password OR
     |       privateKey/passphrase, since these pairings are used together.
     |
    <server>
      <id>deploymentRepo</id>
      <username>repouser</username>
      <password>repopwd</password>

    -->
  </servers>

Mirrors:

  <!-- mirrors
   | This is a list of mirrors to be used in downloading artifacts from remote
   | repositories.
   |
   | It works like this: a POM may declare a repository to use in resolving
   | certain artifacts. However, this repository may have problems with heavy
   | traffic at times, so people have mirrored it to several places.
   |
   | That repository definition will have a unique id, so we can create a
   | mirror reference for that repository, to be used as an alternate download
   | site. The mirror site will be the preferred server for that repository.
   |-->
  <mirrors>
    <!-- mirror
     | Specifies a repository mirror site to use instead of a given repository.
     | The repository that this mirror serves has an ID that matches the
     | mirrorOf element of this mirror. IDs are used for inheritance and direct
     | lookup purposes, and must be unique across the set of mirrors.
     |
    <mirror>
      <id>mirrorId</id>
      <mirrorOf>repositoryId</mirrorOf>
      <name>Human Readable Name for this Mirror.</name>
      <url>http://my.repository.com/repo/path</url>
    </mirror>
     -->
  </mirrors>

Profiles (1/3):

  <!-- profiles
   | This is a list of profiles which can be activated in a variety of ways,
   | and which can modify the build process. Profiles provided in the
   | settings.xml are intended to provide local machine-specific paths and
   | repository locations which allow the build to work in the local
   | environment.
   |
   | For example, if you have an integration testing plugin - like cactus -
   | that needs to know where your Tomcat instance is installed, you can
   | provide a variable here such that the variable is dereferenced during the
   | build process to configure the cactus plugin.
   |
   | As noted above, profiles can be activated in a variety of ways. One
   | way - the activeProfiles section of this document (settings.xml) - will be
   | discussed later. Another way essentially relies on the detection of a
   | system property, either matching a particular value for the property, or
   | merely testing its existence. Profiles can also be activated by JDK
   | version prefix, where a value of '1.4' might activate a profile when the
   | build is executed on a JDK version of '1.4.2_07'. Finally, the list of
   | active profiles can be specified directly from the command line.
   |
   | NOTE: For profiles defined in the settings.xml, you are restricted to
   |       specifying only artifact repositories, plugin repositories, and
   |       free-form properties to be used as configuration variables for
   |       plugins in the POM.
   |
   |-->

Profiles (2/3):

  <profiles>
    <!-- profile
     | Specifies a set of introductions to the build process, to be activated
     | using one or more of the mechanisms described above. For inheritance
     | purposes, and to activate profiles via <activatedProfiles/> or the
     | command line, profiles have to have an ID that is unique.
     |
     | An encouraged best practice for profile identification is to use a
     | consistent naming convention for profiles, such as 'env-dev',
     | 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc. This
     | will make it more intuitive to understand what the set of introduced
     | profiles is attempting to accomplish, particularly when you only have a
     | list of profile id's for debug.
     |
     | This profile example uses the JDK version to trigger activation, and
     | provides a JDK-specific repo.
    <profile>
      <id>jdk-1.4</id>

      <activation>
        <jdk>1.4</jdk>
      </activation>

      <repositories>
        <repository>
          <id>jdk14</id>
          <name>Repository for JDK 1.4 builds</name>
          <url>http://www.myhost.com/maven/jdk14</url>
          <layout>default</layout>
          <snapshotPolicy>always</snapshotPolicy>
        </repository>
      </repositories>
    </profile>
    -->

Profiles (3/3):

    <!--
     | Here is another profile, activated by the system property 'target-env'
     | with a value of 'dev', which provides a specific path to the Tomcat
     | instance. To use this, your plugin configuration might hypothetically
     | look like:
     |
     | ...
     | <plugin>
     |   <groupId>org.myco.myplugins</groupId>
     |   <artifactId>myplugin</artifactId>
     |
     |   <configuration>
     |     <tomcatLocation>${tomcatPath}</tomcatLocation>
     |   </configuration>
     | </plugin>
     | ...
     |
     | NOTE: If you just wanted to inject this configuration whenever someone
     |       set 'target-env' to anything, you could just leave off the
     |       <value/> inside the activation-property.
     |
    <profile>
      <id>env-dev</id>

      <activation>
        <property>
          <name>target-env</name>
          <value>dev</value>
        </property>
      </activation>

      <properties>

   | certain artifacts. However, this repository may have problems with heavy
   | traffic at times, so people have mirrored it to several places.
   |
   | That repository definition will have a unique id, so we can create a
   | mirror reference for that repository, to be used as an alternate download
   | site. The mirror site will be the preferred server for that repository.

    <!-- mirror
     | Specifies a repository mirror site to use instead of a given repository.
     | The repository that this mirror serves has an ID that matches the

  <!-- profiles
   | This is a list of profiles which can be activated in a variety of ways,
   | and which can modify the build process. Profiles provided in the
   | settings.xml are intended to provide local machine-specific paths and
   | repository locations which allow the build to work in the local
   | environment.
   |
   | For example, if you have an integration testing plugin - like cactus -
   | that needs to know where your Tomcat instance is installed, you can
   | provide a variable here such that the variable is dereferenced during the
   | build process to configure the cactus plugin.
   |
   | As noted above, profiles can be activated in a variety of ways. One
   | way - the activeProfiles section of this document (settings.xml) - will be
   | discussed later. Another way essentially relies on the detection of a
   | system property, either matching a particular value for the property, or
   | merely testing its existence. Profiles can also be activated by JDK
   | version prefix, where a value of '1.4' might activate a profile when the
   | build is executed on a JDK version of '1.4.2_07'. Finally, the list of
   | active profiles can be specified directly from the command line.
   |
   | NOTE: For profiles defined in the settings.xml, you are restricted to
   |       specifying only artifact repositories, plugin repositories, and
   |       free-form properties to be used as configuration variables for
   |       plugins in the POM.
   |
   |-->

  <profiles>
    <!-- profile
     | Specifies a set of introductions to the build process, to be activated
     | using one or more of the mechanisms described above. For inheritance
     | purposes, and to activate profiles via <activatedProfiles/> or the
     | command line, profiles have to have an ID that is unique.
     |
     | An encouraged best practice for profile identification is to use a
     | consistent naming convention for profiles, such as 'env-dev',
     | 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc. This
     | will make it more intuitive to understand what the set of introduced
     | profiles is attempting to accomplish, particularly when you only have a
     | list of profile id's for debug.
     |
     | This profile example uses the JDK version to trigger activation, and
     | provides a JDK-specific repo.

I am happy that browsers care to save us from intrusive scripts and the like. I am not happy with IE putting something into the browser that makes a simple style-fix look like a hack-attack!

I've used a < span > to represent the file-input so that I could apply appropriate styling to the < div > instead of the < input > (once again, because of IE). Now due to this IE want's to show the User a path with a value that's just guaranteed to put them on guard and in the very least apprehensive (if not totally scare them off?!)... MORE IE-CRAP!

Anyhow, thanks to to those who posted the explanation here: IE Browser Security: Appending "fakepath" to file path in input[type="file"], I've put together a minor fixer-upper...

The code below does two things - it fixes a lte IE8 bug where the onChange event doesn't fire until the upload field's onBlur and it updates an element with a cleaned filepath that won't scare the User.

// self-calling lambda to for jQuery shorthand "$" namespace
(function($){
    // document onReady wrapper
    $().ready(function(){
        // check for the nefarious IE
        if($.browser.msie) {
            // capture the file input fields
            var fileInput = $('input[type="file"]');
            // add presentational <span> tags "underneath" all file input fields for styling
            fileInput.after(
                $(document.createElement('span')).addClass('file-underlay')
            );
            // bind onClick to get the file-path and update the style <div>
            fileInput.click(function(){
                // need to capture $(this) because setTimeout() is on the
                // Window keyword 'this' changes context in it
                var fileContext = $(this);
                // capture the timer as well as set setTimeout()
                // we use setTimeout() because IE pauses timers when a file dialog opens
                // in this manner we give ourselves a "pseudo-onChange" handler
                var ieBugTimeout = setTimeout(function(){
                    // set vars
                    var filePath     = fileContext.val(),
                        fileUnderlay = fileContext.siblings('.file-underlay');
                    // check for IE's lovely security speil
                    if(filePath.match(/fakepath/)) {
                        // update the file-path text using case-insensitive regex
                        filePath = filePath.replace(/C:\\fakepath\\/i, '');
                    }
                    // update the text in the file-underlay <span>
                    fileUnderlay.text(filePath);
                    // clear the timer var
                    clearTimeout(ieBugTimeout);
                }, 10);
            });
        }
    });
})(jQuery);

None of the above answers worked for me, perhaps they were based on an older version of the framework?

All I needed to do was set the value of the underlying control, then call the refresh method, as below:

$("#slider").val(50);
$("#slider").slider("refresh");

It turns out I didn't have Microsoft visual c++ installed, installing it solved the problem for me.

If you are using the command line to assemble .jar it is possible to point to the main without adding Manifest file. Example:

jar cfve app.jar TheNameOfClassWithMainMethod *.class

(param "e" does that: TheNameOfClassWithMainMethod is a name of the class with the method main() and app.jar - name of executable .jar and *.class - just all classes files to assemble)

Working on a project I was stuck for some time on this concept - I ended up with a similar answer to Method 1 by @GSerg that worked great. Essentially I defined two formula ranges (using a few variables) and then used the Union concept. My example is from a larger project that I'm working on but hopefully the portion of code below can help some other people who might not know how to use the Union concept in conjunction with defined ranges and variables. I didn't include the entire code because at this point it's fairly long - if anyone wants more insight feel free to let me know.

First I declared all my variables as Public

Then I defined/set each variable

Lastly I set a new variable "SelectRanges" as the Union between the two other FormulaRanges

Public r As Long
Public c As Long
Public d As Long
Public FormulaRange3 As Range
Public FormulaRange4 As Range
Public SelectRanges As Range

With Sheet8




  c = pvt.DataBodyRange.Columns.Count + 1

  d = 3

  r = .Cells(.Rows.Count, 1).End(xlUp).Row

Set FormulaRange3 = .Range(.Cells(d, c + 2), .Cells(r - 1, c + 2))
    FormulaRange3.NumberFormat = "0"
    Set FormulaRange4 = .Range(.Cells(d, c + c + 2), .Cells(r - 1, c + c + 2))
    FormulaRange4.NumberFormat = "0"
    Set SelectRanges = Union(FormulaRange3, FormulaRange4)

Off the top of my head:

• Array* - represents an old-school memory array - kind of like a alias for a normal type[] array. Can enumerate. Can't grow automatically. I would assume very fast insert and retrival speed.

• ArrayList - automatically growing array. Adds more overhead. Can enum., probably slower than a normal array but still pretty fast. These are used a lot in .NET

• List - one of my favs - can be used with generics, so you can have a strongly typed array, e.g. List<string>. Other than that, acts very much like ArrayList

• Hashtable - plain old hashtable. O(1) to O(n) worst case. Can enumerate the value and keys properties, and do key/val pairs

• Dictionary - same as above only strongly typed via generics, such as Dictionary<string, string>

• SortedList - a sorted generic list. Slowed on insertion since it has to figure out where to put things. Can enum., probably the same on retrieval since it doesn't have to resort, but deletion will be slower than a plain old list.

I tend to use List and Dictionary all the time - once you start using them strongly typed with generics, its really hard to go back to the standard non-generic ones.

There are lots of other data structures too - there's KeyValuePair which you can use to do some interesting things, there's a SortedDictionary which can be useful as well.

You don't have all digit characters in your string. So you have to split by space

QString Abcd = "123.5 Kb";
Abcd.split(" ")[0].toInt();    //convert the first part to Int
Abcd.split(" ")[0].toDouble(); //convert the first part to double
Abcd.split(" ")[0].toFloat();  //convert the first part to float

Update: I am updating an old answer. That was a straight forward answer to the specific question, with a strict assumption. However as noted by @DomTomCat in comments and @Mikhail in answer, In general one should always check whether the operation is successful or not. So using a boolean flag is necessary.

bool flag;
double v = Abcd.split(" ")[0].toDouble(&flag); 
if(flag){
  // use v
}

Also if you are taking that string as user input, then you should also be doubtful about whether the string is really splitable with space. If there is a possibility that the assumption may break then a regex verifier is more preferable. A regex like the following will extract the floating point value and the prefix character of 'b'. Then you can safely convert the captured strings to double.

([0-9]*\.?[0-9]+)\s+(\w[bB])

You can have an utility function like the following

QPair<double, QString> split_size_str(const QString& str){
    QRegExp regex("([0-9]*\\.?[0-9]+)\\s+(\\w[bB])");
    int pos = regex.indexIn(str);
    QStringList captures = regex.capturedTexts();
    if(captures.count() > 1){
        double value = captures[1].toDouble(); // should succeed as regex matched
        QString unit = captures[2]; // should succeed as regex matched
        return qMakePair(value, unit);
    }
    return qMakePair(0.0f, QString());
}

Ok. I found a program buried deep in other files from the beginning of the year that does what I want. I can't really comment on the suggestions offered because I'm not an experienced spim or low level programmer.Here it is:

         .text
         .globl __start
    __start:
         la $a0,str1 #Load and print string asking for string
         li $v0,4
         syscall

         li $v0,8 #take in input
         la $a0, buffer #load byte space into address
         li $a1, 20 # allot the byte space for string
         move $t0,$a0 #save string to t0
         syscall

         la $a0,str2 #load and print "you wrote" string
         li $v0,4
         syscall

         la $a0, buffer #reload byte space to primary address
         move $a0,$t0 # primary address = t0 address (load pointer)
         li $v0,4 # print string
         syscall

         li $v0,10 #end program
         syscall


               .data
             buffer: .space 20
             str1:  .asciiz "Enter string(max 20 chars): "
             str2:  .asciiz "You wrote:\n"
             ###############################

             #You wrote:

This is a very rudimentary text-based c# program that simulates the spinning action of a slot machine. It doesn't include different odds of winning or cash payouts, but that could be a nice exercise for the students.

Sorry that it is more than 10 lines.

string[] symbols = new[] { "#", "?", "~" }; // The symbols on the reel
Random rand = new Random();

do
{
    string a="",b="",c="";

    for( int i = 0; i < 20; i++ )
    {
        Thread.Sleep( 50 + 25 * i ); // slow down more the longer the loop runs

        if( i < 10 )
            a = symbols[rand.Next( 0, symbols.Length )];

        if( i < 15 )
            b = symbols[rand.Next( 0, symbols.Length )];

        c = symbols[rand.Next( 0, symbols.Length )];

        Console.Clear();
        Console.WriteLine( "Spin: " + a + b + c );
    }

    if( a == b && b == c )
        Console.WriteLine( "You win. Press enter to play again or type \"exit\" to exit" );
    else
        Console.WriteLine( "You lose. Press enter to play again or type \"exit\" to exit" );
}
while( Console.ReadLine() != "exit" );

Using balexandre's info:

SELECT usesysid, usename FROM pg_stat_activity;

Since @Etienne asked how to do this without melting the data (which in general is the preferred method, but I recognize there may be some cases where that is not possible), I present the following alternative.

Start with a subset of the original data:

datos <-
structure(list(fecha = structure(c(1317452400, 1317538800, 1317625200, 
1317711600, 1317798000, 1317884400, 1317970800, 1318057200, 1318143600, 
1318230000, 1318316400, 1318402800, 1318489200, 1318575600, 1318662000, 
1318748400, 1318834800, 1318921200, 1319007600, 1319094000), class = c("POSIXct", 
"POSIXt"), tzone = ""), TempMax = c(26.58, 27.78, 27.9, 27.44, 
30.9, 30.44, 27.57, 25.71, 25.98, 26.84, 33.58, 30.7, 31.3, 27.18, 
26.58, 26.18, 25.19, 24.19, 27.65, 23.92), TempMedia = c(22.88, 
22.87, 22.41, 21.63, 22.43, 22.29, 21.89, 20.52, 19.71, 20.73, 
23.51, 23.13, 22.95, 21.95, 21.91, 20.72, 20.45, 19.42, 19.97, 
19.61), TempMin = c(19.34, 19.14, 18.34, 17.49, 16.75, 16.75, 
16.88, 16.82, 14.82, 16.01, 16.88, 17.55, 16.75, 17.22, 19.01, 
16.95, 17.55, 15.21, 14.22, 16.42)), .Names = c("fecha", "TempMax", 
"TempMedia", "TempMin"), row.names = c(NA, 20L), class = "data.frame")

You can get the desired effect by (and this also cleans up the original plotting code):

ggplot(data = datos, aes(x = fecha)) +
  geom_line(aes(y = TempMax, colour = "TempMax")) +
  geom_line(aes(y = TempMedia, colour = "TempMedia")) +
  geom_line(aes(y = TempMin, colour = "TempMin")) +
  scale_colour_manual("", 
                      breaks = c("TempMax", "TempMedia", "TempMin"),
                      values = c("red", "green", "blue")) +
  xlab(" ") +
  scale_y_continuous("Temperatura (C)", limits = c(-10,40)) + 
  labs(title="TITULO")

The idea is that each line is given a color by mapping the colour aesthetic to a constant string. Choosing the string which is what you want to appear in the legend is the easiest. The fact that in this case it is the same as the name of the y variable being plotted is not significant; it could be any set of strings. It is very important that this is inside the aes call; you are creating a mapping to this "variable".

scale_colour_manual can now map these strings to the appropriate colors. The result is

In some cases, the mapping between the levels and colors needs to be made explicit by naming the values in the manual scale (thanks to @DaveRGP for pointing this out):

ggplot(data = datos, aes(x = fecha)) +
  geom_line(aes(y = TempMax, colour = "TempMax")) +
  geom_line(aes(y = TempMedia, colour = "TempMedia")) +
  geom_line(aes(y = TempMin, colour = "TempMin")) +
  scale_colour_manual("", 
                      values = c("TempMedia"="green", "TempMax"="red", 
                                 "TempMin"="blue")) +
  xlab(" ") +
  scale_y_continuous("Temperatura (C)", limits = c(-10,40)) + 
  labs(title="TITULO")

(giving the same figure as before). With named values, the breaks can be used to set the order in the legend and any order can be used in the values.

ggplot(data = datos, aes(x = fecha)) +
  geom_line(aes(y = TempMax, colour = "TempMax")) +
  geom_line(aes(y = TempMedia, colour = "TempMedia")) +
  geom_line(aes(y = TempMin, colour = "TempMin")) +
  scale_colour_manual("", 
                      breaks = c("TempMedia", "TempMax", "TempMin"),
                      values = c("TempMedia"="green", "TempMax"="red", 
                                 "TempMin"="blue")) +
  xlab(" ") +
  scale_y_continuous("Temperatura (C)", limits = c(-10,40)) + 
  labs(title="TITULO")

If you are on linux systems please try running sudo php artisan migrate As for me,sometimes database operations need to run with sudo in laravel.

You could try something like this (copied from the jQuery Ajax examples)

var request = $.ajax({
  url: "script.php",
  type: "POST",
  data: {id : menuId},
  dataType: "html"
});

request.done(function(msg) {
  console.log( msg );
});

request.fail(function(jqXHR, textStatus) {
  console.log( "Request failed: " + textStatus );
});

The problem with your original code is that the error argument you pass into your on function isn't actually coming from anywhere. JQuery on doesn't return a second argument, and even if it did, it would relate to the click event not the Ajax call.

MarkerImage has been deprecated for Icon

Until version 3.10 of the Google Maps JavaScript API, complex icons were defined as MarkerImage objects. The Icon object literal was added in 3.10, and replaces MarkerImage from version 3.11 onwards. Icon object literals support the same parameters as MarkerImage, allowing you to easily convert a MarkerImage to an Icon by removing the constructor, wrapping the previous parameters in {}'s, and adding the names of each parameter.

Phillippe's code would now be:

 var icon = {
     url: "../res/sit_marron.png", // url
     scaledSize: new google.maps.Size(width, height), // size
     origin: new google.maps.Point(0,0), // origin
     anchor: new google.maps.Point(anchor_left, anchor_top) // anchor 
 };

 position = new google.maps.LatLng(latitud,longitud)
 marker = new google.maps.Marker({
  position: position,
  map: map,
  icon: icon
 });

public interface IMinStack<T extends Comparable<T>> {
  public void push(T val);
  public T pop();
  public T minValue();
  public int size();
}

import java.util.Stack;

public class MinStack<T extends Comparable<T>> implements IMinStack<T> {
  private Stack<T> stack = new Stack<T>();
  private Stack<T> minStack = new Stack<T>();

  @Override
  public void push(T val) {
    stack.push(val);
    if (minStack.isEmpty() || val.compareTo(minStack.peek()) < 0)
        minStack.push(val);
  }

  @Override
  public T pop() {
    T val = stack.pop();

According to the jQuery documentation for .keypress(), it does not catch non-printable characters, so backspace will not work on keypress, but it is caught in keydown and keyup:

The keypress event is sent to an element when the browser registers keyboard input. This is similar to the keydown event, except that modifier and non-printing keys such as Shift, Esc, and delete trigger keydown events but not keypress events. Other differences between the two events may arise depending on platform and browser. (https://api.jquery.com/keypress/)

In some instances keyup isn't desired or has other undesirable effects and keydown is sufficient, so one way to handle this is to use keydown to catch all keystrokes then set a timeout of a short interval so that the key is entered, then do processing in there after.

jQuery(el).keydown( function() { 
    var that = this; setTimeout( function(){ 
           /** Code that processes backspace, etc. **/ 
     }, 100 );  
 } );

It could be too late to answer but I have a shorter and more functional solution in my opinion.

// Inside your onCreate method, add these.
ActionBar actionBar = getSupportActionBar();
actionBar.setHomeButtonEnabled(true);
actionBar.setDisplayHomeAsUpEnabled(true);

// After the method's closing bracket, add the following method exactly as it is and voiulla, a fully functional back arrow appears at the action bar
@Override
public boolean onOptionsItemSelected(MenuItem item) {
    onBackPressed();
    return true;
}

Have you considered letting the user of your application select their own color scheme? Without fail you won't be able to please all of your users with your selection but you can allow them to find what pleases them.

To retrieve your image from byte to base64 string....

Model property:

    public byte[] NomineePhoto { get; set; }

    public string NomineePhoneInBase64Str 
    {
        get {
            if (NomineePhoto == null)
                return "";

            return $"data:image/png;base64,{Convert.ToBase64String(NomineePhoto)}";
        } 
    }

IN view:

   <img style="height:50px;width:50px" src="@item.NomineePhoneInBase64Str" />

Basically you need to look up ArrayList element based on name getName. Two approaches to this problem:

1- Don't use ArrayList, Use HashMap<String,AutionItem> where String would be name

2- Use getName to generate index and use index based addition into array list list.add(int index, E element). One way to generate index from name would be to use its hashCode and modulo by ArrayList current size (something similar what is used inside HashMap)

I would suggest the use of jquery mate.

With jQuery you would then be able to get the id of this element by

$(this).attr('id');

without jquery, if I remember correctly we used to access the id with a

this.id

Hope that helps :)

You're trying to compare your working tree with a particular branch name, so you want this:

git diff master -- foo

Which is from this form of git-diff (see the git-diff manpage)

   git diff [--options] <commit> [--] [<path>...]
       This form is to view the changes you have in your working tree
       relative to the named <commit>. You can use HEAD to compare it with
       the latest commit, or a branch name to compare with the tip of a
       different branch.

FYI, there is also a --cached (aka --staged) option for viewing the diff of what you've staged, rather than everything in your working tree:

   git diff [--options] --cached [<commit>] [--] [<path>...]
       This form is to view the changes you staged for the next commit
       relative to the named <commit>.
       ...
       --staged is a synonym of --cached.

The reason the first code sample doesn't work is because the layout of the page changed. As per the warning on that page: "The translated string is fetched by the RegEx close to the bottom. This could of course change, and you have to keep it up to date." I think this should work for now, at least until they change the page again.

public string TranslateText(string input, string languagePair)
{
    string url = String.Format("http://www.google.com/translate_t?hl=en&ie=UTF8&text={0}&langpair={1}", input, languagePair);
    WebClient webClient = new WebClient();
    webClient.Encoding = System.Text.Encoding.UTF8;
    string result = webClient.DownloadString(url);
    result = result.Substring(result.IndexOf("<span title=\"") + "<span title=\"".Length);
    result = result.Substring(result.IndexOf(">") + 1);
    result = result.Substring(0, result.IndexOf("</span>"));
    return result.Trim();
}

Below you have some VALID html5 example document. The type attribute in script tag is not mandatory in HTML5.

You use jquery by $ charater. Put libraries (like jquery) in <head> tag - but your script put allways at the bottom of document (<body> tag) - due this you will be sure that all libraries and html document will be loaded when your script execution starts. You can also use src attribute in bottom script tag to include you script file instead of putting direct js code like above.

<!doctype html>_x000D_
<html lang="en">_x000D_
<head>_x000D_
    <meta charset="utf-8">_x000D_
    <title>Example</title>_x000D_
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>_x000D_
</head>_x000D_
<body>_x000D_
    <div>Im the content</div>_x000D_
_x000D_
    <script>_x000D_
        alert( $('div').text() ); // show message with div content_x000D_
    </script>_x000D_
</body>_x000D_
</html>

I was looking to determine if two sets had equivalent contents, in any order. That meant that, for each element in set A there were equal numbers of elements with that value in both sets. I wanted to account for duplicates (so {1,2,2,3} and {1,2,3,3} should not be considered "the same").

This is what I came up with (note that IsNullOrEmpty is another static extension method that returns true if the enumerable is null or has 0 elements):

    public static bool HasSameContentsAs<T>(this IEnumerable<T> source, IEnumerable<T> target) 
        where T : IComparable
    {
        //If our source is null or empty, then it's just a matter of whether or not the target is too
        if (source.IsNullOrEmpty())
            return target.IsNullOrEmpty();

        //Otherwise, if the target is null/emtpy, they can't be equal
        if (target.IsNullOrEmpty())
            return false;

        //Neither is null or empty, so we'll compare contents.  To account for multiples of 
        //a given value (ex. 1,2,2,3 and 1,1,2,3 are not equal) we'll group the first set
        foreach (var group in source.GroupBy(s => s))
        {
            //If there are a different number of elements in the target set, they don't match
            if (target.Count(t => t.Equals(group.Key)) != group.Count())
                return false;
        }

        //If we got this far, they have the same contents
        return true;
    }

You can use the iterator that is returned by the begin() method of the map template:

std::map<K,V> myMap;
std::pair<K,V> firstEntry = *myMap.begin()

But remember that the std::map container stores its content in an ordered way. So the first entry is not always the first entry that has been added.

The problem is that if you try to write a <table> or a <tr> or <td> tag using JS every time you insert a new tag the browser will try to close it as it will think that there is an error on the code.

Instead of writing your table line by line, concatenate your table into a variable and insert it once created:

<script language="javascript" type="text/javascript">
<!--

var myArray    = new Array();
    myArray[0] = 1;
    myArray[1] = 2.218;
    myArray[2] = 33;
    myArray[3] = 114.94;
    myArray[4] = 5;
    myArray[5] = 33;
    myArray[6] = 114.980;
    myArray[7] = 5;

    var myTable= "<table><tr><td style='width: 100px; color: red;'>Col Head 1</td>";
    myTable+= "<td style='width: 100px; color: red; text-align: right;'>Col Head 2</td>";
    myTable+="<td style='width: 100px; color: red; text-align: right;'>Col Head 3</td></tr>";

    myTable+="<tr><td style='width: 100px;                   '>---------------</td>";
    myTable+="<td     style='width: 100px; text-align: right;'>---------------</td>";
    myTable+="<td     style='width: 100px; text-align: right;'>---------------</td></tr>";

  for (var i=0; i<8; i++) {
    myTable+="<tr><td style='width: 100px;'>Number " + i + " is:</td>";
    myArray[i] = myArray[i].toFixed(3);
    myTable+="<td style='width: 100px; text-align: right;'>" + myArray[i] + "</td>";
    myTable+="<td style='width: 100px; text-align: right;'>" + myArray[i] + "</td></tr>";
  }  
   myTable+="</table>";

 document.write( myTable);

//-->
</script> 

If your code is in an external JS file, in HTML create an element with an ID where you want your table to appear:

<div id="tablePrint"> </div>

And in JS instead of document.write(myTable) use the following code:

document.getElementById('tablePrint').innerHTML = myTable;

Setting CSS width to 1% or 100% of an element according to all specs I could find out is related to the parent. Although Blink Rendering Engine (Chrome) and Gecko (Firefox) at the moment of writing seems to handle that 1% or 100% (make a columns shrink or a column to fill available space) well, it is not guaranteed according to all CSS specifications I could find to render it properly.

One option is to replace table with CSS4 flex divs:

https://css-tricks.com/snippets/css/a-guide-to-flexbox/

That works in new browsers i.e. IE11+ see table at the bottom of the article.

Adding the following lines to a new script will clear all variables each time you rerun the script:

from IPython import get_ipython
get_ipython().magic('reset -sf') 

To make life easy, you can add them to your default template.

In Spyder: Tools>Preferences>Editor>Edit template

let transactionId =${new Date().getDate()}${new Date().getHours()}${new Date().getSeconds()}${new Date().getMilliseconds()}

let transactionId =`${new Date().getDate()}${new Date().getHours()}${new Date().getSeconds()}${new Date().getMilliseconds()}` 

console.log(transactionId)

In regards to your question about newlines and carriage returns:

I would recommend using the predefined global constant PHP_EOL as it will solve any cross-platform compatibility issues.

This question has been raised on SO beforehand and you can find out more information by reading "When do I use the PHP constant PHP_EOL"

Well, another working solution based on Cody's answer but a little more general can be something like this:

function timedAlert(msg, timing){
    setTimeout(function(){
        alert(msg);    
    }, timing);
}

function yourFunction(time, counter){
    for (var i = 1; i <= counter; i++) {
        var msg = i, timing = i * time * 1000; //this is in seconds
        timedAlert (msg, timing);
    };
}

yourFunction(timeInSeconds, counter); // well here are the values of your choice.

I found "kill -0" does not work if the process is owned by root (or other), so I used pgrep and came up with:

while pgrep -u root process_name > /dev/null; do sleep 1; done

This would have the disadvantage of probably matching zombie processes.

Just for the fun, I'm offering an alternative solution using jOOQ and Java 8. Instead of using jOOQ, you could be using any other API that maps JDBC ResultSet to List, such as Spring JDBC or Apache DbUtils, or write your own ResultSetIterator:

jOOQ 3.8 or less

List<Object> list =
DSL.using(connection)
   .fetch("SELECT col1, col2, col3, ...")
   .stream()
   .flatMap(r -> Arrays.stream(r.intoArray()))
   .collect(Collectors.toList());

jOOQ 3.9

List<Object> list =
DSL.using(connection)
   .fetch("SELECT col1, col2, col3, ...")
   .stream()
   .flatMap(Record::intoStream)
   .collect(Collectors.toList());

(Disclaimer, I work for the company behind jOOQ)

The best way is:

1. Right-click on the output panel.
2. Choose view frame source, then the whole code will appear.

After that you can copy that code, and paste it in your computer.

I think that the the align="center" aligns the content, so if you wanted to use that method, you would need to use it in a 'wraper' div - a div that just wraps the rest.

text-align is doing a similar sort of thing.

left:50% is ignored unless you set the div's position to be something like relative or absolute.

The generally accepted methods is to use the following properties

width:500px; // this can be what ever unit you want, you just have to define it
margin-left:auto;
margin-right:auto;

the margins being auto means they grow/shrink to match the browser window (or parent div)

UPDATE

Thanks to Meo for poiting this out, if you wanted to you could save time and use the short hand propery for the margin.

margin:0 auto;

this defines the top and bottom as 0 (as it is zero it does not matter about lack of units) and the left and right get defined as 'auto' You can then, if you wan't override say the top margin as you would with any other CSS rules.

Thanks @rmaddy, I added this just after other key-string pairs in Info.plist and fixed the problem:

<key>NSPhotoLibraryUsageDescription</key>
<string>Photo Library Access Warning</string>

Edit:

I also ended up having similar problems on different components of my app. Ended up adding all these keys so far (after updating to Xcode8/iOS10):

<key>NSPhotoLibraryUsageDescription</key>
<string>This app requires access to the photo library.</string>
<key>NSMicrophoneUsageDescription</key>
<string>This app does not require access to the microphone.</string>
<key>NSCameraUsageDescription</key>
<string>This app requires access to the camera.</string>

I've found a solution for me with Spring and jackson

First specify the filter name in the entity

@Entity
@Table(name = "SECTEUR")
@JsonFilter(ModelJsonFilters.SECTEUR_FILTER)
public class Secteur implements Serializable {

/** Serial UID */
private static final long serialVersionUID = 5697181222899184767L;

/**
 * Unique ID
 */
@Id
@JsonView(View.SecteurWithoutChildrens.class)
@Column(name = "id")
@GeneratedValue(strategy = GenerationType.IDENTITY)
private long id;

@JsonView(View.SecteurWithoutChildrens.class)
@Column(name = "code", nullable = false, length = 35)
private String code;

/**
 * Identifiant du secteur parent
 */
@JsonView(View.SecteurWithoutChildrens.class)
@Column(name = "id_parent")
private Long idParent;

@OneToMany(fetch = FetchType.LAZY)
@JoinColumn(name = "id_parent")
private List<Secteur> secteursEnfants = new ArrayList<>(0);

}

Then you can see the constants filters names class with the default FilterProvider used in spring configuration

public class ModelJsonFilters {

public final static String SECTEUR_FILTER = "SecteurFilter";
public final static String APPLICATION_FILTER = "ApplicationFilter";
public final static String SERVICE_FILTER = "ServiceFilter";
public final static String UTILISATEUR_FILTER = "UtilisateurFilter";

public static SimpleFilterProvider getDefaultFilters() {
    SimpleBeanPropertyFilter theFilter = SimpleBeanPropertyFilter.serializeAll();
    return new SimpleFilterProvider().setDefaultFilter(theFilter);
}

}

Spring configuration :

@EnableWebMvc
@Configuration
@ComponentScan(basePackages = "fr.sodebo")

public class ApiRootConfiguration extends WebMvcConfigurerAdapter {

@Autowired
private EntityManagerFactory entityManagerFactory;


/**
 * config qui permet d'éviter les "Lazy loading Error" au moment de la
 * conversion json par jackson pour les retours des services REST<br>
 * on permet à jackson d'acceder à sessionFactory pour charger ce dont il a
 * besoin
 */
@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {

    super.configureMessageConverters(converters);
    MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
    ObjectMapper mapper = new ObjectMapper();

    // config d'hibernate pour la conversion json
    mapper.registerModule(getConfiguredHibernateModule());//

    // inscrit les filtres json
    subscribeFiltersInMapper(mapper);

    // config du comportement de json views
    mapper.configure(MapperFeature.DEFAULT_VIEW_INCLUSION, false);

    converter.setObjectMapper(mapper);
    converters.add(converter);
}

/**
 * config d'hibernate pour la conversion json
 * 
 * @return Hibernate5Module
 */
private Hibernate5Module getConfiguredHibernateModule() {
    SessionFactory sessionFactory = entityManagerFactory.unwrap(SessionFactory.class);
    Hibernate5Module module = new Hibernate5Module(sessionFactory);
    module.configure(Hibernate5Module.Feature.FORCE_LAZY_LOADING, true);

    return module;

}

/**
 * inscrit les filtres json
 * 
 * @param mapper
 */
private void subscribeFiltersInMapper(ObjectMapper mapper) {

    mapper.setFilterProvider(ModelJsonFilters.getDefaultFilters());

}

}

Endly I can specify a specific filter in restConstoller when i need....

@RequestMapping(value = "/{id}/droits/", method = RequestMethod.GET)
public MappingJacksonValue getListDroits(@PathVariable long id) {

    LOGGER.debug("Get all droits of user with id {}", id);

    List<Droit> droits = utilisateurService.findDroitsDeUtilisateur(id);

    MappingJacksonValue value;

    UtilisateurWithSecteurs utilisateurWithSecteurs = droitsUtilisateur.fillLists(droits).get(id);

    value = new MappingJacksonValue(utilisateurWithSecteurs);

    FilterProvider filters = ModelJsonFilters.getDefaultFilters().addFilter(ModelJsonFilters.SECTEUR_FILTER, SimpleBeanPropertyFilter.serializeAllExcept("secteursEnfants")).addFilter(ModelJsonFilters.APPLICATION_FILTER,
            SimpleBeanPropertyFilter.serializeAllExcept("services"));

    value.setFilters(filters);
    return value;

}

I was crazy to delete node and npm and nodejs from my Ubuntu 14.04 but with this steps you will remove it:

sudo apt-get uninstall nodejs npm node
sudo apt-get remove nodejs npm node

If you uninstall correctly and it is still there, check these links:

• Stack Overflow answer with more information
• Remove npm - Official website
• Stack Overflow answer for uninstalling if you installed via git repository
• Try purging nodejs npm and node

You can also try using find:

find / -name "node"

Although since that is likely to take a long time and return a lot of confusing false positives, you may want to search only PATH locations:

find $(echo $PATH | sed 's/:/ /g') -name "node"

It would probably be in /usr/bin/node or /usr/local/bin. After finding it, you can delete it using the correct path, eg:

sudo rm /usr/bin/node

Hi try bellow link it is very easy. I've been stuck for long time and it solve my issue in few minutes. http://simpleupload.michaelcbrook.com/#examples

import requests

url = 'https://example.tld/'
auth = ('username', 'password')

r = requests.get(url, auth=auth)
print r.content

This is the simplest I've been able to get it.

I tried all the above answers, but inserting or removing items to recyclerview causes problem with the position in the dataSet. Ended up using delete(getAdapterPosition()); inside the viewHolder which worked great at finding the position of items.

We can create a unique ID in java by using the UUID and call the method like randomUUID() on UUID.

String uniqueID = UUID.randomUUID().toString();

This will generate the random uniqueID whose return type will be String.

You could also do

SELECT row FROM table ORDER BY id DESC LIMIT 1;

This will sort rows by their ID in descending order and return the first row. This is the same as returning the row with the maximum ID. This of course assumes that id is unique among all rows. Otherwise there could be multiple rows with the maximum value for id and you'll only get one.

Hibernate queries are case sensitive with property names (because they end up relying on getter/setter methods on the @Entity).

Make sure you refer to the property as fileName in the Criteria query, not filename.

Specifically, Hibernate will call the getter method of the filename property when executing that Criteria query, so it will look for a method called getFilename(). But the property is called FileName and the getter getFileName().

So, change the projection like so:

criteria.setProjection(Projections.property("fileName"));

set "html" option to true if you want to have html into tooltip. Actual html is determined by option "title" (link's title attribute shouldn't be set)

$('#example1').tooltip({placement: 'bottom', title: '<p class="testtooltip">par</p>', html: true});

Live sample

You aren't building your formula right.

Worksheets("EmployeeCosts").Range("B" & var1a).Formula =  "=SUM(H5:H" & var1a & ")"

This does the same as the following lines do:

Dim myFormula As String
myFormula = "=SUM(H5:H"
myFormula = myFormula & var1a
myformula = myformula & ")"

which is what you are trying to do.

Also, you want to have the = at the beginning of the formala.

Just see if the "C:\Program Files (x86)" exists. If not, then you are on a 32 bit OS. If it does, then the OS is 64 bit (Windows Vista or Windows 7). It seems simple enough...

The problem with the first answer is that the placeholder will be uppercase too. In case you want ONLY the input to be uppercase, use the following solution.

In order to select only non-empty input element, put required attribute on the element:

<input type="text" id="name-input" placeholder="Enter symbol" required="required" />

Now, in order to select it, use the :valid pseudo-element:

#name-input:valid { text-transform: uppercase; }

This way you will uppercase only entered characters.

for this find the given Object in an Array, a basic usage example of _.find

const array = 
[
{
    description: 'object1', id: 1
},
{
    description: 'object2', id: 2
},
{
    description: 'object3', id: 3
},
{
    description: 'object4', id: 4
}
];

this would work well

q = _.find(array, {id:'4'}); // delete id

console.log(q); // {description: 'object4', id: 4}

_.find will help with returning an element in an array, rather than it’s index. So if you have an array of objects and you want to find a single object in the array by a certain key value pare _.find is the right tools for the job.

You can insert new data into table by two ways.

1. Load the data of a file into table using load command.

   LOAD DATA [LOCAL] INPATH 'filepath' [OVERWRITE] INTO TABLE tablename.
   

2. You can insert new data into table by using select query.

   INSERT INTO table tablename1 select columnlist FROM secondtable;
   

value_counts work only for series. It won't work for entire DataFrame. Try selecting only one column and using this attribute. For example:

df['accepted'].value_counts()

It also won't work if you have duplicate columns. This is because when you select a particular column, it will also represent the duplicate column and will return dataframe instead of series. At that time remove duplicate column by using

df = df.loc[:,~df.columns.duplicated()]
df['accepted'].value_counts()

First step is to load your xml string into an XmlDocument, using powershell's unique ability to cast strings to [xml]

$doc = [xml]@'
<xml>
    <Section name="BackendStatus">
        <BEName BE="crust" Status="1" />
        <BEName BE="pizza" Status="1" />
        <BEName BE="pie" Status="1" />
        <BEName BE="bread" Status="1" />
        <BEName BE="Kulcha" Status="1" />
        <BEName BE="kulfi" Status="1" />
        <BEName BE="cheese" Status="1" />
    </Section>
</xml>
'@

Powershell makes it really easy to parse xml with the dot notation. This statement will produce a sequence of XmlElements for your BEName elements:

$doc.xml.Section.BEName

Then you can pipe these objects into the where-object cmdlet to filter down the results. You can use ? as a shortcut for where

$doc.xml.Section.BEName | ? { $_.Status -eq 1 }

The expression inside the braces will be evaluated for each XmlElement in the pipeline, and only those that have a Status of 1 will be returned. The $_ operator refers to the current object in the pipeline (an XmlElement).

If you need to do something for every object in your pipeline, you can pipe the objects into the foreach-object cmdlet, which executes a block for every object in the pipeline. % is a shortcut for foreach:

$doc.xml.Section.BEName | ? { $_.Status -eq 1 } | % { $_.BE + " is delicious" }

Powershell is great at this stuff. It's really easy to assemble pipelines of objects, filter pipelines, and do operations on each object in the pipeline.

docker build -t {image name} -v {host directory}:{temp build directory} .

This is another way to copy files into an image. The -v option temporarily creates a volume that us used during the build process.

This is different that other volumes because it mounts a host directory for the build only. Files can be copied using a standard cp command.

Also, like the curl and wget, it can be run in a command stack (runs in a single container) and not multiply the image size. ADD and COPY are not stackable because they run in a standalone container and subsequent commands on those files that execute in additional containers will multiply the image size:

With the options set thus:

-v /opt/mysql-staging:/tvol

The following will execute in one container:

RUN cp -r /tvol/mysql-5.7.15-linux-glibc2.5-x86_64 /u1 && \
    mv /u1/mysql-5.7.15-linux-glibc2.5-x86_64 /u1/mysql && \

    mkdir /u1/mysql/mysql-files && \
    mkdir /u1/mysql/innodb && \
    mkdir /u1/mysql/innodb/libdata && \
    mkdir /u1/mysql/innodb/innologs && \
    mkdir /u1/mysql/tmp && \

    chmod 750 /u1/mysql/mysql-files && \
    chown -R mysql /u1/mysql && \
    chgrp -R mysql /u1/mysql

Question is quite old, but I created some possible solution how to create abstract "class" and block creation of object that type.

//our Abstract class_x000D_

As You can see last object give us error, it is because Animal in prototype has property abstract. To be sure it is Animal not something which has Animal.prototype in prototype chain I do:

Object.getPrototypeOf(this).hasOwnProperty("abstract")

So I check that my closest prototype object has abstract property, only object created directly from Animal prototype will have this condition on true. Function hasOwnProperty checks only properties of current object not his prototypes, so this gives us 100% sure that property is declared here not in prototype chain.

Every object descended from Object inherits the hasOwnProperty method. This method can be used to determine whether an object has the specified property as a direct property of that object; unlike the in operator, this method does not check down the object's prototype chain. More about it:

In my proposition we not have to change constructor every time after Object.create like it is in current best answer by @Jordão.

Solution also enables to create many abstract classes in hierarchy, we need only to create abstract property in prototype.

Use INTERSECT operator.

It's NULL-sensitive and efficient if you have a composite index on all your fields:

IF      EXISTS
        (
        SELECT  MY_FIELD1, MY_FIELD2, MY_FIELD3, MY_FIELD4, MY_FIELD5, MY_FIELD6
        FROM    MY_TABLE
        INTERSECT
        SELECT  @IN_MY_FIELD1, @IN_MY_FIELD2, @IN_MY_FIELD3, @IN_MY_FIELD4, @IN_MY_FIELD5, @IN_MY_FIELD6
        )
BEGIN
        goto on_duplicate
END

Note that if you create a UNIQUE index on your fields, your life will be much simpler.

Thanks for this! I'd liek to add a little riff on the J-P's answer - I don't know if this will help anyone, but this way you don't have to create an array of images, and you can preload all your large images if you name your thumbs correctly. This is handy because I have someone who is writing all the pages in html, and it ensures one less step for them to do - eliminating the need to create the image array, and another step where things could get screwed up.

$("img").each(function(){
    var imgsrc = $(this).attr('src');
    if(imgsrc.match('_th.jpg') || imgsrc.match('_home.jpg')){
      imgsrc = thumbToLarge(imgsrc);
      (new Image()).src = imgsrc;   
    }
});

Basically, for each image on the page it grabs the src of each image, if it matches certain criteria (is a thumb, or home page image) it changes the name(a basic string replace in the image src), then loads the images.

In my case the page was full of thumb images all named something like image_th.jpg, and all the corresponding large images are named image_lg.jpg. The thumb to large just replaces the _th.jpg with _lg.jpg and then preloads all the large images.

Hope this helps someone.

You may be overcomplicating things, is there any reason you need the stringr package?

 df <- data.frame(Date = c("10/9/2009 0:00:00", "10/15/2009 0:00:00"))
 as.Date(df$Date, "%m/%d/%Y %H:%M:%S")

[1] "2009-10-09" "2009-10-15"

More generally and if you need the time component as well, use strptime:

strptime(df$Date, "%m/%d/%Y %H:%M:%S")

I'm guessing at what your actual data might look at from the partial results you give.

As was posted earlier, you need to make sure you install the platform plugins when you deploy your application. Depending on how you want to deploy things, there are two methods to tell your application where the platform plugins (e.g. platforms/plugins/libqxcb.so) are at runtime which may work for you.

The first is to export the path to the directory through the QT_QPA_PLATFORM_PLUGIN_PATH variable.

QT_QPA_PLATFORM_PLUGIN_PATH=path/to/plugins ./my_qt_app

or

export QT_QPA_PLATFORM_PLUGIN_PATH=path/to/plugins
./my_qt_app

The other option, which I prefer is to create a qt.conf file in the same directory as your executable. The contents of which would be:

[Paths]
Plugins=/path/to/plugins

More information regarding this can be found here and at using qt.conf

As a developer, you should probably start learning set operations (difference, union, intersection). You can imagine your array as one "set", and the keys you are searching for the other.

Check if ALL needles exist

function in_array_all($needles, $haystack) {
   return empty(array_diff($needles, $haystack));
}

echo in_array_all( [3,2,5], [5,8,3,1,2] ); // true, all 3, 2, 5 present
echo in_array_all( [3,2,5,9], [5,8,3,1,2] ); // false, since 9 is not present

Check if ANY of the needles exist

function in_array_any($needles, $haystack) {
   return !empty(array_intersect($needles, $haystack));
}

echo in_array_any( [3,9], [5,8,3,1,2] ); // true, since 3 is present
echo in_array_any( [4,9], [5,8,3,1,2] ); // false, neither 4 nor 9 is present

As I have seen it, java.util.Timer is the most used for implementing a timer.

For a repeating task:

new Timer().scheduleAtFixedRate(task, after, interval);

For a single run of a task:

new Timer().schedule(task, after);

task being the method to be executed
after the time to initial execution
(interval the time for repeating the execution)

I have written a small module to do just that, called timexe:

• Its simple,small reliable code and has no dependencies
• Resolution is in milliseconds and has high precision over time
• Cron like, but not compatible (reversed order and other Improvements)
• I works in the browser too

Install:

npm install timexe

use:

var timexe = require('timexe');
//Every 30 sec
var res1=timexe(”* * * * * /30”, function() console.log(“Its time again”)});

//Every minute
var res2=timexe(”* * * * *”,function() console.log(“a minute has passed”)});

//Every 7 days
var res3=timexe(”* y/7”,function() console.log(“its the 7th day”)});

//Every Wednesdays 
var res3=timexe(”* * w3”,function() console.log(“its Wednesdays”)});

// Stop "every 30 sec. timer"
timexe.remove(res1.id);

you can achieve start/stop functionality by removing/re-adding the entry directly in the timexe job array. But its not an express function.

And just to provide a contrast, there's also pip.

Use NodePort:

$ kubectl run user-login --replicas=2 --labels="run=user-login" --image=kingslayerr/teamproject:version2  --port=5000

$ kubectl expose deployment user-login --type=NodePort --name=user-login-service

$ kubectl describe services user-login-service

(Note down the port)

$ kubectl cluster-info

(IP-> Get The IP where master is running)

Your service is accessible at (IP):(port)

I was wondering if/how I can 'create' a html page for each database row?

You just need to create one php file that generate an html template, what changes is the text based content on that page. In that page is where you can get a parameter (eg. row id) via POST or GET and then get the info form the database.

I'm assuming this would be better for SEO?

Search Engine as Google interpret that example.php?id=33 and example.php?id=44 are different pages, and yes, this way is better than single listing page from the SEO point of view, so you just need two php files at least (listing.php and single.php), because is better link this pages from the listing.php.

Extra advice:

example.php?id=33 is really ugly and not very seo friendly, maybe you need some url rewriting code. Something like example/properties/property-name is better ;)

SQLite3 supports the REGEXP operator:

WHERE x REGEXP <regex>

http://www.sqlite.org/lang_expr.html#regexp

See What is the maximum length of a URL in different browsers?

The length of the url can't be changed in PHP. The linked question is about the URL size limit, you will find what you want.

This usually happens when debugging using the emulator, which is known to be slow anyway.

Angular 2.x to 8 Compatible!

You can directly give the source property of the current object in the img src attribute. Please see my code below:

<div *ngFor="let brochure of brochureList">
    <img class="brochure-poster" [src]="brochure.imageUrl" />
</div>

NOTE: You can as well use string interpolation but that is not a legit way to do it. Property binding was created for this very purpose hence better use this.

NOT RECOMMENDED :

<img class="brochure-poster" src="{{brochure.imageUrl}}"/>

Its because that defeats the purpose of property binding. It is more meaningful to use that for setting the properties. {{}} is a normal string interpolation expression, that does not reveal to anyone reading the code that it makes special meaning. Using [] makes it easily to spot the properties that are set dynamically.

Here is my brochureList contains the following json received from service(you can assign it to any variable):

[ {
            "productId":1,
            "productName":"Beauty Products",
            "productCode": "XXXXXX",            
            "description":  "Skin Care",           
            "imageUrl":"app/Images/c1.jpg"
         },
        {
             "productId":2,
            "productName":"Samsung Galaxy J5",
            "productCode": "MOB-124",      
            "description":  "8GB, Gold",
            "imageUrl":"app/Images/c8.jpg"
         }]

You should always include the table name in the SQL query when dealing with associations.

Indeed if another table has the user_id column and you join both tables, you will have an ambiguous column name in the SQL query (i.e. troubles).

So, in your example:

GroupUser.where("groups_users.user_id != ?", me)

Or a bit more verbose:

GroupUser.where("#{table_name}.user_id IS NOT ?", me)

Note that if you are using a hash, you don't need to worry about that because Rails takes care of it for you:

GroupUser.where(user: me)

In Rails 4, as said by @dr4k3, the query method not has been added:

GroupUser.where.not(user: me)

You simply need to start mysql and feed it with the content of db.sql:

mysql -u user -p < db.sql

It allows browsers to determine if they can handle the scripting/style language before making a request for the script or stylesheet (or, in the case of embedded script/style, identify which language is being used).

This would be much more important if there had been more competition among languages in browser space, but VBScript never made it beyond IE and PerlScript never made it beyond an IE specific plugin while JSSS was pretty rubbish to begin with.

See the Postgresql manual's entry on this for more details.

Paxdiablo's definition is really good.

In addition, please consider delivering an uber-jar is sometimes quite useful, if you really want to distribute a software and don't want customer to download dependencies by themselves. As a draw back, if their own policy don't allow usage of some library, or if they have to bind some extra-components (slf4j, system compliant libs, arch specialiez libs, ...) this will probably increase difficulties for them.

You can perform that :

• basically with maven-assembly-plugin
• a bit more further with maven-shade-plugin

A cleaner solution is to provide their library separately; maven-shade-plugin has preconfigured descriptor for that. This is not more complicated to do (with maven and its plugin).

Finally, a really good solution is to use an OSGI Bundle. There is plenty of good tutorials on that :)

For further configuration, please read those topics :

• Should you provide dependent libraries in client jar?
• Best practices in building and deploying Clojure applications: good tutorials?

you can use jquery validator for that but you need to add jquery.validate.js and jquery.form.js file for that. after including validator file define your validation something like this.

<script type="text/javascript">
$(document).ready(function(){
    $("#formID").validate({
    rules :{
        "data[User][name]" : {
            required : true
        }
    },
    messages :{
        "data[User][name]" : {
            required : 'Enter username'
        }
    }
    });
});
</script>

You can see required : true same there is many more property like for email you can define email : true for number number : true

Use the Out-File cmdlet

 Compare-Object ... | Out-File C:\filename.txt

Optionally, add -Encoding utf8 to Out-File as the default encoding is not really ideal for many uses.

clear project and then run. it will work

The "directory where postgresql will keep all databases" (and configuration) is called "data directory" and corresponds to what PostgreSQL calls (a little confusingly) a "database cluster", which is not related to distributed computing, it just means a group of databases and related objects managed by a PostgreSQL server.

The location of the data directory depends on the distribution. If you install from source, the default is /usr/local/pgsql/data:

In file system terms, a database cluster will be a single directory under which all data will be stored. We call this the data directory or data area. It is completely up to you where you choose to store your data. There is no default, although locations such as /usr/local/pgsql/data or /var/lib/pgsql/data are popular. (ref)

Besides, an instance of a running PostgreSQL server is associated to one cluster; the location of its data directory can be passed to the server daemon ("postmaster" or "postgres") in the -D command line option, or by the PGDATA environment variable (usually in the scope of the running user, typically postgres). You can usually see the running server with something like this:

[root@server1 ~]# ps auxw |  grep postgres | grep -- -D
postgres  1535  0.0  0.1  39768  1584 ?        S    May17   0:23 /usr/local/pgsql/bin/postgres -D /usr/local/pgsql/data

Note that it is possible, though not very frequent, to run two instances of the same PostgreSQL server (same binaries, different processes) that serve different "clusters" (data directories). Of course, each instance would listen on its own TCP/IP port.

Use the Socket() constructor, and connect(SocketAddress endpoint, int timeout) method instead.

In your case it would look something like:

Socket socket = new Socket();
socket.connect(new InetSocketAddress(ipAddress, port), 1000);

Quoting from the documentation

connect

public void connect(SocketAddress endpoint, int timeout) throws IOException

Connects this socket to the server with a specified timeout value. A timeout of zero is interpreted as an infinite timeout. The connection will then block until established or an error occurs.

Parameters:

endpoint - the SocketAddress
timeout - the timeout value to be used in milliseconds.

Throws:

IOException - if an error occurs during the connection
SocketTimeoutException - if timeout expires before connecting
IllegalBlockingModeException - if this socket has an associated channel, and the channel is in non-blocking mode
IllegalArgumentException - if endpoint is null or is a SocketAddress subclass not supported by this socket

I know I am 3 years late on this thread, however still providing my 2 cents for similar cases in future.

I recently faced the same issue/error in my cluster. The JOB would always get to some 80%+ reduction and fail with the same error, with nothing to go on in the execution logs either. Upon multiple iterations and research I found that among the plethora of files getting loaded some were non-compliant with the structure provided for the base table(table being used to insert data into partitioned table).

Point to be noted here is whenever I executed a select query for a particular value in the partitioning column or created a static partition it worked fine as in that case error records were being skipped.

TL;DR: Check the incoming data/files for inconsistency in the structuring as HIVE follows Schema-On-Read philosophy.

Since the onItemClickLitener() will itself provide you the index of the selected item, you can simply do a getItemAtPosition(i).toString(). The code snippet is given below :-

    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {

            String s = listView.getItemAtPosition(i).toString();

            Toast.makeText(activity.getApplicationContext(), s, Toast.LENGTH_LONG).show();
            adapter.dismiss(); // If you want to close the adapter
        }
    });

On the method above, the i parameter actually gives you the position of the selected item.

One of the best resources I found was using let's encrypt, you do not need ELB nor cloudfront for your EC2 instance to have HTTPS, just follow the following simple instructions: let's encrypt Login to your server and follow the steps in the link.

It is also important as mentioned by others that you have port 443 opened by editing your security groups

You can view your certificate or any other website's by changing the site name in this link

Please do not forget that it is only valid for 90 days

Since .NET Framework 3.5 there is also a HashSet<T> which provides all the pros of the Dictionary<TKey, TValue> if you need only the keys and no values.

So if you use a Dictionary<MyType, object> and always set the value to null to simulate the type safe hash table you should maybe consider switching to the HashSet<T>.

I do understand, that your question was about files stored in MEDIA_ROOT, but sometimes it can be possible to store content in static, when you are not planning to create content of that type anymore.
May be this is a rare case, but anyway - if you have a huge amount of "pictures of the day" for your site - and all these files are on your hard drive?

In that case I see no contra to store such a content in STATIC.
And all becomes really simple:

static

To link to static files that are saved in STATIC_ROOT Django ships with a static template tag. You can use this regardless if you're using RequestContext or not.

{% load static %} <img src="{% static "images/hi.jpg" %}" alt="Hi!" />

copied from Official django 1.4 documentation / Built-in template tags and filters

if you are using Conda environment, you should set up config file again. And file location will be something like this. I did not setup config file after I created env in Conda and that was my connection problem.

C:\Users\syurt\AppData\Local\Continuum\anaconda3\envs\myenv\share\jupyter\jupyter_notebook_config.py

For python 3 it would be like this n,m,p=map(int,input().split())

As hadley mentioned there are more effective ways of communicating your message than labels in stacked bar charts. In fact, stacked charts aren't very effective as the bars (each Category) doesn't share an axis so comparison is hard.

It's almost always better to use two graphs in these instances, sharing a common axis. In your example I'm assuming that you want to show overall total and then the proportions each Category contributed in a given year.

library(grid)
library(gridExtra)
library(plyr)

# create a new column with proportions
prop <- function(x) x/sum(x)
Data <- ddply(Data,"Year",transform,Share=prop(Frequency))

# create the component graphics
totals <- ggplot(Data,aes(Year,Frequency)) + geom_bar(fill="darkseagreen",stat="identity") + 
  xlab("") + labs(title = "Frequency totals in given Year")
proportion <- ggplot(Data, aes(x=Year,y=Share, group=Category, colour=Category)) 
+ geom_line() + scale_y_continuous(label=percent_format())+ theme(legend.position = "bottom") + 
  labs(title = "Proportion of total Frequency accounted by each Category in given Year")

# bring them together
grid.arrange(totals,proportion)

This will give you a 2 panel display like this:

If you want to add Frequency values a table is the best format.

There are a few ways to go about this. One option would be to use inputfile.read() instead of inputfile.readlines() - you'd need to write separate code to strip the first four lines, but if you want the final output as a single string anyway, this might make the most sense.

A second, simpler option would be to rejoin the strings after striping the first four lines with my_text = ''.join(my_text). This is a little inefficient, but if speed isn't a major concern, the code will be simplest.

Finally, if you actually want the output as a list of strings instead of a single string, you can just modify your data parser to iterate over the list. That might looks something like this:

def data_parser(lines, dic):
    for i, j in dic.iteritems():
        for (k, line) in enumerate(lines):
            lines[k] = line.replace(i, j)
    return lines

On my Linux machine :

git config --system --get https.proxy (returns nothing)
git config --global --get https.proxy (returns nothing)

git config --system --get http.proxy (returns nothing)
git config --global --get http.proxy (returns nothing)

I found out my https_proxy and http_proxy are set, so I just unset them.

unset https_proxy
unset http_proxy

On my Windows machine :

set https_proxy=""
set http_proxy=""

Optionally use setx to set environment variables permanently on Windows and set system environment using "/m"

setx https_proxy=""
setx http_proxy=""

Yes, it is normal. This is because you checkout a single commit, that doesnt have a head. Especially it is (sooner or later) not a head of any branch.

But there is usually no problem with that state. You may create a new branch from the tag, if this makes you feel safer :)

In my case below code

    <?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:top="10dp" android:bottom="-10dp"

        <shape android:shape="rectangle">
            <solid android:color="@color/maincolor" />

            <corners
                android:topLeftRadius="10dp"
                android:topRightRadius="10dp"
                android:bottomLeftRadius="0dp"

Following up on Niketya's answer, there's a good explanation of Pivot Tables here: http://peltiertech.com/WordPress/grouping-by-date-in-a-pivot-table/

For Excel 2007 you'd create the Pivot Table, make your Date column a Row Label, your Amount column a value. You'd then right click on one of the row labels (ie a date), right click and select Group. You'd then get the option to group by day, month, etc.

Personally that's the way I'd go.

If you prefer formulae, Smandoli's answer would get you most of the way there. To be able to use Sumif by day, you'd add a column with a formula like:

=DATE(YEAR(C1), MONTH(C1), DAY(C1))

where column C contains your datetimes.

You can then use this in your sumif.

Well there are 2 methods:

Method 1: A well-known method for renaming database schema is by dumping the schema using Mysqldump and restoring it in another schema, and then dropping the old schema (if needed).

From Shell

 mysqldump emp > emp.out
 mysql -e "CREATE DATABASE employees;"
 mysql employees < emp.out 
 mysql -e "DROP DATABASE emp;"

Although the above method is easy, it is time and space consuming. What if the schema is more than a 100GB? There are methods where you can pipe the above commands together to save on space, however it will not save time.

To remedy such situations, there is another quick method to rename schemas, however, some care must be taken while doing it.

Method 2: MySQL has a very good feature for renaming tables that even works across different schemas. This rename operation is atomic and no one else can access the table while its being renamed. This takes a short time to complete since changing a table’s name or its schema is only a metadata change. Here is procedural approach at doing the rename:

1. Create the new database schema with the desired name.
2. Rename the tables from old schema to new schema, using MySQL’s “RENAME TABLE” command.
3. Drop the old database schema.

If there are views, triggers, functions, stored procedures in the schema, those will need to be recreated too. MySQL’s “RENAME TABLE” fails if there are triggers exists on the tables. To remedy this we can do the following things :

1) Dump the triggers, events and stored routines in a separate file. This done using -E, -R flags (in addition to -t -d which dumps the triggers) to the mysqldump command. Once triggers are dumped, we will need to drop them from the schema, for RENAME TABLE command to work.

  $ mysqldump <old_schema_name> -d -t -R -E > stored_routines_triggers_events.out

2) Generate a list of only “BASE” tables. These can be found using a query on information_schema.TABLES table.

 mysql> select TABLE_NAME from information_schema.tables where 
    table_schema='<old_schema_name>' and TABLE_TYPE='BASE TABLE';

3) Dump the views in an out file. Views can be found using a query on the same information_schema.TABLES table.

mysql> select TABLE_NAME from information_schema.tables where 
   table_schema='<old_schema_name>' and TABLE_TYPE='VIEW';
 $ mysqldump <database> <view1> <view2> … > views.out

4) Drop the triggers on the current tables in the old_schema.

mysql> DROP TRIGGER <trigger_name>;
...

5) Restore the above dump files once all the “Base” tables found in step #2 are renamed.

mysql> RENAME TABLE <old_schema>.table_name TO <new_schema>.table_name;
...
$ mysql <new_schema> < views.out
$ mysql <new_schema> < stored_routines_triggers_events.out

Intricacies with above methods : We may need to update the GRANTS for users such that they match the correct schema_name. These could fixed with a simple UPDATE on mysql.columns_priv, mysql.procs_priv, mysql.tables_priv, mysql.db tables updating the old_schema name to new_schema and calling “Flush privileges;”. Although “method 2" seems a bit more complicated than the “method 1", this is totally scriptable. A simple bash script to carry out the above steps in proper sequence, can help you save space and time while renaming database schemas next time.

The Percona Remote DBA team have written a script called “rename_db” that works in the following way :

[root@dba~]# /tmp/rename_db
rename_db <server> <database> <new_database>

To demonstrate the use of this script, used a sample schema “emp”, created test triggers, stored routines on that schema. Will try to rename the database schema using the script, which takes some seconds to complete as opposed to time consuming dump/restore method.

mysql> show databases;

| mysql              |
| performance_schema |

+--------------------+

As you can see in the above output the database schema “emp” was renamed to “emp_test” in less than a second. Lastly, This is the script from Percona that is used above for “method 2".

Well, timing to the rescue again. It seems switch is generally faster than if statements. So that, and the fact that the code is shorter/neater with a switch statement leans in favor of switch:

# Simplified to only measure the overhead of switch vs if

test1 <- function(type) {
 switch(type,
        mean = 1,
        median = 2,
        trimmed = 3)
}

test2 <- function(type) {
 if (type == "mean") 1
 else if (type == "median") 2
 else if (type == "trimmed") 3
}

system.time( for(i in 1:1e6) test1('mean') ) # 0.89 secs
system.time( for(i in 1:1e6) test2('mean') ) # 1.13 secs
system.time( for(i in 1:1e6) test1('trimmed') ) # 0.89 secs
system.time( for(i in 1:1e6) test2('trimmed') ) # 2.28 secs

Update With Joshua's comment in mind, I tried other ways to benchmark. The microbenchmark seems the best. ...and it shows similar timings:

> library(microbenchmark)
> microbenchmark(test1('mean'), test2('mean'), times=1e6)
Unit: nanoseconds
           expr  min   lq median   uq      max
1 test1("mean")  709  771    864  951 16122411
2 test2("mean") 1007 1073   1147 1223  8012202

> microbenchmark(test1('trimmed'), test2('trimmed'), times=1e6)
Unit: nanoseconds
              expr  min   lq median   uq      max
1 test1("trimmed")  733  792    843  944 60440833
2 test2("trimmed") 2022 2133   2203 2309 60814430

Final Update Here's showing how versatile switch is:

switch(type, case1=1, case2=, case3=2.5, 99)

This maps case2 and case3 to 2.5 and the (unnamed) default to 99. For more information, try ?switch

I don't know of anything similar to java's response to SIGQUIT, so you might have to build it in to your application. Maybe you could make a server in another thread that can get a stacktrace on response to a message of some kind?

You could use somehting like

<ul>
   <li><a href="#">Some text<span><br />Some text</span></a></li>
</ul>

and then in your css just set the span content bold and hide it with visibility: hidden, so that it keeps its dimensions. Then you can adjust margins of the following elements to make it fit properly.

I am not sure if this approach is SEO friendly though.

There doesn't seem to be justify-self, but you can achieve similar result setting appropriate margin to auto¹. E. g. for flex-direction: row (default) you should set margin-right: auto to align the child to the left.

.container {_x000D_
  height: 100px;_x000D_
  border: solid 10px skyblue;_x000D_
  _x000D_
  display: flex;_x000D_
  justify-content: flex-end;_x000D_
}_x000D_
.block {_x000D_
  width: 50px;_x000D_
  background: tomato;_x000D_
}_x000D_
.justify-start {_x000D_
  margin-right: auto;_x000D_
}

<div class="container">_x000D_
  <div class="block justify-start"></div>_x000D_
  <div class="block"></div>_x000D_
</div>

¹ This behaviour is defined by the Flexbox spec.

Be very very careful renaming objects in sql. You can cause dependencies to fail if you are not fully away with what you are doing. Having said that this works easily(too much so) for renaming things provided you have access proper on the environment:

exec sp_rename 'Nameofobject', 'ReNameofobject'

Chances are that you've not included the header file that declares system().

In order to be able to compile C++ code that uses functions which you don't (manually) declare yourself, you have to pull in the declarations. These declarations are normally stored in so-called header files that you pull into the current translation unit using the #include preprocessor directive. As the code does not #include the header file in which system() is declared, the compilation fails.

To fix this issue, find out which header file provides you with the declaration of system() and include that. As mentioned in several other answers, you most likely want to add #include <cstdlib>

For money: decimal. It costs a little more memory, but doesn't have rounding troubles like double sometimes has.

Change your code:

a.image_container img {
    width: 100%;
}

To this:

a.image_container img {
    width: auto; // to maintain aspect ratio. You can use 100% if you don't care about that
    height: 100%;
}

You are just missing to make it raw. The issue is with "\". Adding r before the path would do the work :)

<?php

function takes_array($input)

{

    echo "$input[0] + $input[1] = ", $input[0]+$input[1];

You can do

var modal = {} as IModal 

It's called designated initializer which is introduced in C99. It's used to initialize struct or arrays, in this example, struct.

Given

struct point { 
    int x, y;
};

the following initialization

struct point p = { .y = 2, .x = 1 };

is equivalent to the C89-style

struct point p = { 1, 2 };

Try This

SELECT Title  from #Movies
    SELECT CASE WHEN Title = '' THEN 'No Title' ELSE Title END AS Titile from #Movies

OR

SELECT [Id], [CategoryId], ISNULL(nullif(Title,''),'No data') as Title, [Director], [DateReleased] FROM #Movies

Building on Will Shepard's answer, his output will include duplicate lines for commits where there was no change, so you can filter those as as follows (using this answer)

LINE=1 FILE=a; for commit in $(git rev-list HEAD $FILE); do git blame -n -L$LINE,+1 $commit -- $FILE; done | sed '$!N; /^\(.*\)\n\1$/!P; D'

Note that I removed the REVS argument and this goes back to the root commit. This is due to Max Nanasy's observation above.

Try this code:

Bitmap bitmap = null;
File f = new File(_path);
BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
try {
    bitmap = BitmapFactory.decodeStream(new FileInputStream(f), null, options);
} catch (FileNotFoundException e) {
    e.printStackTrace();
}         
image.setImageBitmap(bitmap);

Because the inequality operator in VBA is <>

If strTest <> "" Then
    .....

the operator != is used in C#, C++.

I already found the solution to this problem which I forgot to post here.

@RunWith(PowerMockRunner.class)
@PrepareForTest({ Test.class })
public class SampleTest {

@Mock
Person person;

@Test
public void testPrintName() throws Exception {
    PowerMockito.whenNew(Person.class).withNoArguments().thenReturn(person);
    Test test= new Test();
    test.testMethod();
    }
}

Key points to this solution are:

1. Running my test cases with PowerMockRunner: @RunWith(PowerMockRunner.class)

2. Instruct Powermock to prepare Test.class for manipulation of private fields: @PrepareForTest({ Test.class })

3. And finally mock the constructor for Person class:

   PowerMockito.mockStatic(Person.class); PowerMockito.whenNew(Person.class).withNoArguments().thenReturn(person);

OK, after 2 years it's finally time to correct the syntax:

SELECT  t1.value, t2.value
FROM    MyTable t1
JOIN    MyTable t2
ON      t1.id = t2.id
WHERE   t1.id = @id
        AND t1.status = @status1
        AND t2.status = @status2

A little more elegant way of doing the same adding on to the above comment ..

In plain JavaScript, simply use response = readline() after printing a prompt.

In Node.js, you'll need to use the readline module: const readline = require('readline')

There is no selector in CSS which does this. Attribute selectors match attribute values, not computed values.

You would have to use JavaScript.

.push() will add elements to the end of an array.

Use .unshift() if need to add some element to the beginning of array i.e:

items.unshift({'id':5});

Demo:

items = [{'id': 1}, {'id': 2}, {'id': 3}, {'id': 4}];_x000D_
items.unshift({'id': 0});_x000D_
console.log(items);

And use .splice() in case you want to add object at a particular index i.e:

items.splice(2, 0, {'id':5});
           // ^ Given object will be placed at index 2...

Demo:

items = [{'id': 1}, {'id': 2}, {'id': 3}, {'id': 4}];_x000D_
items.splice(2, 0, {'id': 2.5});_x000D_
console.log(items);

May be it look's like this:

Cache

var node = $('.selector')[0];
OR
var node = document.querySelector('.selector');

Set CSS

node.style.setProperty('width', '100px', 'important');

Remove CSS

node.style.removeProperty('width');
OR
node.style.width = '';

This has to be done during your exe4j configuration. In the fourth step of Exe4j wizard which is Executable Info select> Advanced options select 32-bit or 64-bit. This worked well for me. or else install both JDK tool-kits x64 and x32 in your machine.

You can use Joda time library for Java. It would be much easier to calculate time-diff between dates with it.

Sample snippet for time-diff:

Days d = Days.daysBetween(startDate, endDate);
int days = d.getDays();

in order:

FROM & JOINs determine & filter rows
WHERE more filters on the rows
GROUP BY combines those rows into groups
HAVING filters groups
ORDER BY arranges the remaining rows/groups
LIMIT filters on the remaining rows/groups

This is one of those instances where jquery actually makes it more complicated than what the DOM already provides.

let { top, bottom, height, width, //etc } = $('#bottom')[0].getBoundingClientRect();
return top;

Write as

<input type="submit" ng-click="profileForm.$valid==true?updateMyProfile():''" name="submit" value="Save" class="submit" id="submit">

The package react-app-rewired can be used to remove the plugin. This way you do not have to eject.

Follow the steps on the npm package page (install the package and flip the calls in the package.json file) and use a config-overrides.js file similar to this one:

const ModuleScopePlugin = require('react-dev-utils/ModuleScopePlugin');

module.exports = function override(config, env) {
    config.resolve.plugins = config.resolve.plugins.filter(plugin => !(plugin instanceof ModuleScopePlugin));

    return config;
};

This will remove the ModuleScopePlugin from the used WebPack plugins, but leave the rest as it was and removes the necessity to eject.

this is for swift 4.2, 5 and 5+

let alert = UIAlertController(title: "ooops!", message: "Unable to login", preferredStyle: .alert)

alert.addAction(UIAlertAction(title: "Ok", style: .default, handler: nil))

self.present(alert, animated: true)

I came across this thread while trying to clear the date already set. Attempting:

$('#datepicker').val('').datepicker('update');

produced:

TypeError: t.dpDiv is undefined 
https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.2/jquery-ui.min.js -- Line 8

Thinking that perhaps one needed to include the original Datepicker for bootstrap removes the error, but then causes the original Datepicker widget to appear! - so that's obviously wrong and not needed.

Looking further, the crash in jqueryui is in:

    /* Generate the date picker content. */
_updateDatepicker: function(inst) {
    this.maxRows = 4; //Reset the max number of rows being displayed (see #7043)
    datepicker_instActive = inst; // for delegate hover events
    inst.dpDiv.empty().append(this._generateHTML(inst));
    this._attachHandlers(inst);

and inst.pdDiv does not exist.

Investigating further - I realized that what was needed was:

        $formControl = $duedate.find("input");
        $formControl.val('');
        $formControl.removeData();

Which solved my problem. Note I also needed the $formControl.removeData() otherwise the state of the widget would not be reinitialized to the initial state.

I hope this helps someone else. :-)

Use:

Get-ChildItem \\myserver\myshare\myshare\ -Directory | Select-Object -Property name |  convertto-csv -NoTypeInformation  | Out-File c:\temp\mydirectorylist.csv

Which does the following

• Get a list of directories in the target location: Get-ChildItem \\myserver\myshare\myshare\ -Directory
• Extract only the name of the directories: Select-Object -Property name
• Convert the output to CSV format: convertto-csv -NoTypeInformation
• Save the result to a file: Out-File c:\temp\mydirectorylist.csv

I have tried this

return this.db.collection('items').snapshotChanges().pipe(
          map(actions => {       
            return actions.map(a => {
              const data = a.payload.doc.data() as Item;
              data.id = a.payload.doc.id;
              data.$key = a.payload.doc.id;
              return data;
            });
          })
        );

For this gcc error, you should reference to to the gcc document about Search Path.

In short:

1) If you use angle brackets(<>) with #include, gcc will search header file firstly from system path such as /usr/local/include and /usr/include, etc.

2) The path specified by -Ldir command-line option, will be searched before the default directories.

3)If you use quotation("") with #include as #include "file", the directory containing the current file will be searched firstly.

so, the answer to your question is as following:

1) If you want to use header files in your source code folder, replace <> with "" in #include directive.

2) if you want to use -I command line option, add it to your compile command line.(if set CFLAGS in environment variables, It will not referenced automatically)

3) About package configuration(openssl.pc), I do not think it will be referenced without explicitly declared in build configuration.

Tested on Ideone.

import json
array = '{"fruits": ["apple", "banana", "orange"]}'
data  = json.loads(array)
fruits_list = data['fruits']
print fruits_list

The ternary operator ? : is to return a value, don't use it when you want to use if for flow control.

if (compareChar(curChar, toChar("0"))) getButtons().get(i).setText("§");

would work good enough.

Using either a float or a double value in a C expression will result in a value that is a double anyway, so printf can't tell the difference. Whereas a pointer to a double has to be explicitly signalled to scanf as distinct from a pointer to float, because what the pointer points to is what matters.

An alternative solution inspired by the accepted response, but that uses an inverted logic:

MODE="${1}"

echo "<${MODE}>"
[[ "${MODE}" =~ ^(preview|live|both)$ ]] && echo "OK" || echo "Uh?"

Here, the input ($MODE) must be one of the options in the regular expression ('preview', 'live', or 'both'), contrary to matching the whole options list to the user input. Of course, you do not expect the regular expression to change.

As others stated, it's likely failing because the requested key doesn't exist in the array. I have a helper function here that takes the array, the suspected key, as well as a default return in the event the key does not exist.

    protected function _getArrayValue($array, $key, $default = null)
    {
        if (isset($array[$key])) return $array[$key];
        return $default;
    }

hope it helps.
