For Ubntu Users

 1. Install compilers
    #sudo apt-get install make
    #sudo apt-get install gcc

    2. Install openssl and development libraries
    #sudo apt-get install openssl
    #sudo apt-get install libssl-dev
    3. Install the APR package (Downloaded from http://apr.apache.org/)

    #tar -xzf apr-1.4.6.tar.gz
    #cd apr-1.4.6/
    #sudo ./configure
    #sudo make
    #sudo make install

    You should see the compiled file as
    /usr/local/apr/lib/libapr-1.a

    4. Download, compile and install Tomcat Native sourse package
    tomcat-native-1.1.27-src.tar.gz

    Extract the archive into some folder

    #tar -xzf tomcat-native-1.1.27-src.tar.gz
    #cd tomcat-native-1.1.27-src/jni/native
    #JAVA_HOME=/usr/lib/jvm/jdk1.7.0_21/
    #sudo ./configure --with-apr=/usr/local/apr --with-java-home=$JAVA_HOME
    #sudo make
    #sudo make install

    Now I have compiled Tomcat Native library in /usr/local/apr/libtcnative-1.so.0.1.27 and symbolic link file /usr/local/apr/@libtcnative-1.so pointed to the library

    5. Create or edit the $CATALINA_HOME/bin/setenv.sh file with following lines :
    export LD_LIBRARY_PATH='$LD_LIBRARY_PATH:/usr/local/apr/lib'

    6. Restart tomcat and see the desired result:

Since everything is an expression, and thus results in a value, you can just use if/else.

a = if true then 5 else 10
a = if false then 5 else 10

You can see more about expression examples here.

For support to all API levels you can use it like this:

ViewPropertyAnimator.animate(view).translationYBy(-yourY).translationXBy(-yourX).setDuration(0);

mongod --dbpath "c://data/db"

run the above code, this will start the server.

This is correct query for join 3 table with same id**

select a.empname,a.empsalary,b.workstatus,b.bonus,c.dateofbirth from employee a, Report b,birth c where a.empid=b.empid and a.empid=c.empid and b.empid='103';

employee first table. report second table. birth third table

I just wanted to add that "Include" is part of eager loading. It is described in Entity Framework 6 tutorial by Microsoft. Here is the link: https://docs.microsoft.com/en-us/aspnet/mvc/overview/getting-started/getting-started-with-ef-using-mvc/reading-related-data-with-the-entity-framework-in-an-asp-net-mvc-application

Excerpt from the linked page:

Here are several ways that the Entity Framework can load related data into the navigation properties of an entity:

Lazy loading. When the entity is first read, related data isn't retrieved. However, the first time you attempt to access a navigation property, the data required for that navigation property is automatically retrieved. This results in multiple queries sent to the database — one for the entity itself and one each time that related data for the entity must be retrieved. The DbContext class enables lazy loading by default.

Eager loading. When the entity is read, related data is retrieved along with it. This typically results in a single join query that retrieves all of the data that's needed. You specify eager loading by using the Include method.

Explicit loading. This is similar to lazy loading, except that you explicitly retrieve the related data in code; it doesn't happen automatically when you access a navigation property. You load related data manually by getting the object state manager entry for an entity and calling the Collection.Load method for collections or the Reference.Load method for properties that hold a single entity. (In the following example, if you wanted to load the Administrator navigation property, you'd replace Collection(x => x.Courses) with Reference(x => x.Administrator).) Typically you'd use explicit loading only when you've turned lazy loading off.

Because they don't immediately retrieve the property values, lazy loading and explicit loading are also both known as deferred loading.

This happens because $cOTLdata is not null but the index 'char_data' does not exist. Previous versions of PHP may have been less strict on such mistakes and silently swallowed the error / notice while 7.4 does not do this anymore.

To check whether the index exists or not you can use isset():

isset($cOTLdata['char_data'])

Which means the line should look something like this:

$len = isset($cOTLdata['char_data']) ? count($cOTLdata['char_data']) : 0;

Note I switched the then and else cases of the ternary operator since === null is essentially what isset already does (but in the positive case).

This is an old question, but I posted a comment in 2014 and frequently come back to this. I thought I would leave a full answer. This isn't the shortest solution but it is quite easy to understand.

Insert a new value into an associative array, at a numbered position, preserving keys, and preserving order.

$columns = array(
    'id' => 'ID',
    'name' => 'Name',
    'email' => 'Email',
    'count' => 'Number of posts'
);

$columns = array_merge(
    array_slice( $columns, 0, 3, true ),     // The first 3 items from the old array
    array( 'subscribed' => 'Subscribed' ),   // New value to add after the 3rd item
    array_slice( $columns, 3, null, true )   // Other items after the 3rd
);

print_r( $columns );

/*
Array ( 
    [id] => ID 
    [name] => Name 
    [email] => Email 
    [subscribed] => Subscribed 
    [count] => Number of posts 
)
*/

It's really just a coding style. The compiler generates the exact same for both variants.

See also here for the performance question:

• Will using 'var' affect performance?

i use zend studio for eclipse with the built in debugger. Its still slow compared to debugging with eclipse pdt with xdebug. Hopefully they will fix those issues, the speed has improved over the recent releases but still stepping over things takes 2-3 seconds. The zend firefox toolbar really makes things easy (debug next page, current page, etc). Also it provides a profiler that will benchmark your code and provide pie-charts, execution time, etc.

According to Wikipedia,

Views can provide many advantages over tables:

• Views can represent a subset of the data contained in a table.

• Views can limit the degree of exposure of the underlying tables to the outer world: a given user may have permission to query the view, while denied access to the rest of the base table.

• Views can join and simplify multiple tables into a single virtual table.

• Views can act as aggregated tables, where the database engine aggregates data (sum, average, etc.) and presents the calculated results as part of the data.

• Views can hide the complexity of data. For example, a view could appear as Sales2000 or Sales2001, transparently partitioning the actual underlying table.

• Views take very little space to store; the database contains only the definition of a view, not a copy of all the data that it presents.

• Views can provide extra security, depending on the SQL engine used.

You can't do this: {this.state.arrayFromJson} As your error suggests what you are trying to do is not valid. You are trying to render the whole array as a React child. This is not valid. You should iterate through the array and render each element. I use .map to do that.

I am pasting a link from where you can learn how to render elements from an array with React.

http://jasonjl.me/blog/2015/04/18/rendering-list-of-elements-in-react-with-jsx/

Hope it helps!

You can do this for webkit:

#text2::-webkit-input-placeholder::before {
    color:#666;
    content:"Line 1\A Line 2\A Line 3\A";
}

http://jsfiddle.net/Z3tFG/1/

You can pass array of variables to the compact as an arguement eg:

return view('yourView', compact(['var1','var2',....'varN']));

in view: if var1 is an object you can use it something like this

@foreach($var1 as $singleVar1)
    {{$singleVar1->property}}
@endforeach

incase of single variable you can simply

{{$var2}}

i have done this several times without any issues

I suppose you want form based authentication using deployment descriptors and j_security_check.

You can also do this in JSF by just using the same predefinied field names j_username and j_password as demonstrated in the tutorial.

E.g.

<form action="j_security_check" method="post">
    <h:outputLabel for="j_username" value="Username" />
    <h:inputText id="j_username" />
    <br />
    <h:outputLabel for="j_password" value="Password" />
    <h:inputSecret id="j_password" />
    <br />
    <h:commandButton value="Login" />
</form>

You could do lazy loading in the User getter to check if the User is already logged in and if not, then check if the Principal is present in the request and if so, then get the User associated with j_username.

package com.stackoverflow.q2206911;

import java.io.IOException;
import java.security.Principal;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.context.FacesContext;

@ManagedBean
@SessionScoped
public class Auth {

    private User user; // The JPA entity.

    @EJB
    private UserService userService;

    public User getUser() {
        if (user == null) {
            Principal principal = FacesContext.getCurrentInstance().getExternalContext().getUserPrincipal();
            if (principal != null) {
                user = userService.find(principal.getName()); // Find User by j_username.
            }
        }
        return user;
    }

}

The User is obviously accessible in JSF EL by #{auth.user}.

To logout do a HttpServletRequest#logout() (and set User to null!). You can get a handle of the HttpServletRequest in JSF by ExternalContext#getRequest(). You can also just invalidate the session altogether.

public String logout() {
    FacesContext.getCurrentInstance().getExternalContext().invalidateSession();
    return "login?faces-redirect=true";
}

For the remnant (defining users, roles and constraints in deployment descriptor and realm), just follow the Java EE 6 tutorial and the servletcontainer documentation the usual way.

Update: you can also use the new Servlet 3.0 HttpServletRequest#login() to do a programmatic login instead of using j_security_check which may not per-se be reachable by a dispatcher in some servletcontainers. In this case you can use a fullworthy JSF form and a bean with username and password properties and a login method which look like this:

<h:form>
    <h:outputLabel for="username" value="Username" />
    <h:inputText id="username" value="#{auth.username}" required="true" />
    <h:message for="username" />
    <br />
    <h:outputLabel for="password" value="Password" />
    <h:inputSecret id="password" value="#{auth.password}" required="true" />
    <h:message for="password" />
    <br />
    <h:commandButton value="Login" action="#{auth.login}" />
    <h:messages globalOnly="true" />
</h:form>

And this view scoped managed bean which also remembers the initially requested page:

@ManagedBean
@ViewScoped
public class Auth {

    private String username;
    private String password;
    private String originalURL;

    @PostConstruct
    public void init() {
        ExternalContext externalContext = FacesContext.getCurrentInstance().getExternalContext();
        originalURL = (String) externalContext.getRequestMap().get(RequestDispatcher.FORWARD_REQUEST_URI);

        if (originalURL == null) {
            originalURL = externalContext.getRequestContextPath() + "/home.xhtml";
        } else {
            String originalQuery = (String) externalContext.getRequestMap().get(RequestDispatcher.FORWARD_QUERY_STRING);

            if (originalQuery != null) {
                originalURL += "?" + originalQuery;
            }
        }
    }

    @EJB
    private UserService userService;

    public void login() throws IOException {
        FacesContext context = FacesContext.getCurrentInstance();
        ExternalContext externalContext = context.getExternalContext();
        HttpServletRequest request = (HttpServletRequest) externalContext.getRequest();

        try {
            request.login(username, password);
            User user = userService.find(username, password);
            externalContext.getSessionMap().put("user", user);
            externalContext.redirect(originalURL);
        } catch (ServletException e) {
            // Handle unknown username/password in request.login().
            context.addMessage(null, new FacesMessage("Unknown login"));
        }
    }

    public void logout() throws IOException {
        ExternalContext externalContext = FacesContext.getCurrentInstance().getExternalContext();
        externalContext.invalidateSession();
        externalContext.redirect(externalContext.getRequestContextPath() + "/login.xhtml");
    }

    // Getters/setters for username and password.
}

This way the User is accessible in JSF EL by #{user}.

You can use "system.properties.os", for example:

public class GetOs {

  public static void main (String[] args) {
    String s = 
      "name: " + System.getProperty ("os.name");
    s += ", version: " + System.getProperty ("os.version");
    s += ", arch: " + System.getProperty ("os.arch");
    System.out.println ("OS=" + s);
  }
}

// EXAMPLE OUTPUT: OS=name: Windows 7, version: 6.1, arch: amd64

You can see marked answer on top. But i used getDialog().getCurrentFocus() and working well. I post this answer cause i cant type "this" in my oncreatedialog.

So this is my answer. If you tried marked answer and not worked , you can simply try this:

InputMethodManager inputManager = (InputMethodManager) getActivity().getApplicationContext().getSystemService(Context.INPUT_METHOD_SERVICE);
inputManager.hideSoftInputFromWindow(getDialog().getCurrentFocus().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);

The answer by Pomber is acceptable, however I'm not a big fan of creating new objects repeatedly. The best solutions are always the ones that try to mitigate memory hog. Yes, there is auto garbage collection but memory conservation in a mobile device falls within the confines of best practice. The code below updates a TextView in a service.

TextViewUpdater textViewUpdater = new TextViewUpdater();
Handler textViewUpdaterHandler = new Handler(Looper.getMainLooper());
private class TextViewUpdater implements Runnable{
    private String txt;
    @Override
    public void run() {
        searchResultTextView.setText(txt);
    }
    public void setText(String txt){
        this.txt = txt;
    }

}

It can be used from anywhere like this:

textViewUpdater.setText("Hello");
        textViewUpdaterHandler.post(textViewUpdater);

All of the answers above are correct, for the case of DISTINCT on a single column vs GROUP BY on a single column. Every db engine has its own implementation and optimizations, and if you care about the very little difference (in most cases) then you have to test against specific server AND specific version! As implementations may change...

BUT, if you select more than one column in the query, then the DISTINCT is essentially different! Because in this case it will compare ALL columns of all rows, instead of just one column.

So if you have something like:

// This will NOT return unique by [id], but unique by (id,name)
SELECT DISTINCT id, name FROM some_query_with_joins

// This will select unique by [id].
SELECT id, name FROM some_query_with_joins GROUP BY id

It is a common mistake to think that DISTINCT keyword distinguishes rows by the first column you specified, but the DISTINCT is a general keyword in this manner.

So people you have to be careful not to take the answers above as correct for all cases... You might get confused and get the wrong results while all you wanted was to optimize!

In the .gitconfig file you can add the below given value to make the self signed cert acceptable

sslCAInfo = /home/XXXX/abc.crt

If you do want to use null values with '=' or '<>' operators you may find the

answer from @egallardo hier

very useful.

Short example for '=': The expression

WHERE t.field = :param

you refactor like this

WHERE ((:param is null and t.field is null) or t.field = :param)

Now you can set the parameter param either to some non-null value or to null:

query.setParameter("param", "Hello World"); // Works
query.setParameter("param", null);          // Works also

I took the liberty to expand the answer from nona-urbiz; just add this to your ~/.bashrc:

git-pullall () { for RMT in $(git remote); do git pull -v $RMT $1; done; }    
alias git-pullall=git-pullall

git-pushall () { for RMT in $(git remote); do git push -v $RMT $1; done; }
alias git-pushall=git-pushall

Usage:

git-pullall master

git-pushall master ## or
git-pushall

If you do not provide any branch argument for git-pullall then the pull from non-default remotes will fail; left this behavior as it is, since it's analogous to git.

Set the Current Cell like:

DataGridView1.CurrentCell = DataGridView1.Rows[rowindex].Cells[columnindex]

or

DataGridView1.CurrentCell = DataGridView1.Item("ColumnName", 5)

and you can directly focus with Editing by:

dataGridView1.BeginEdit(true)

Well, since you asked for R equivalent to other languages, I tried to do this. Seems to work though I haven't really looked at which technique is more efficient in R.

For the categorical columns though, it would fetch you a Data Frame which you could typecast using as.character() if needed.

I Have 10 Columns in my table and there is 2 columns of dates, 2nd column and 4th column is of US Date, so this is worked for me fine. Just paste this code at last in your script section in same sequence.

   jQuery.fn.dataTableExt.oSort['us_date-asc'] = function (a, b) {
        var x = new Date(a),
            y = new Date(b);
        return ((x < y) ? -1 : ((x > y) ? 1 : 0));
    };


    jQuery.fn.dataTableExt.oSort['us_date-desc'] = function (a, b) {
        var x = new Date(a),
            y = new Date(b);
        return ((x < y) ? 1 : ((x > y) ? -1 : 0));
    };


    $('#tblPoSetupGrid').dataTable({
        columnDefs: [
            { type: 'us_date', targets: 3 },
            { type: 'us_date', targets: 1 }
        ]

    });

Always check if your java files are in src/main/java and not on some other directory path.

import pandas as pd
df = pd.DataFrame([{'Product': 'Coke', 'Prices': [100,123,101,105,99,94,98]},{'Product': 'Pepsi', 'Prices': [101,104,104,101,99,99,99]}])
print(df)
df = df.assign(Prices=df.Prices.str.split(',')).explode('Prices')
print(df)

Try this in pandas >=0.25 version

If you want to checkout all the files 'anywhere'

git checkout -- $(git rev-parse --show-toplevel)

I had to go through a bit more to force a refresh in VS 2008.

First, there is a Data Sources pane/toolbox (menu trail = Data > Show Data Sources), and a Report Data Sources dialog (menu trail = Report > Data Sources). I had trouble with the Data Sources pane reverting to an earlier property list every time I opened a certain report; it was as if the report designer was overwriting the data definition with the report's cached version thereof.

To remedy this, I had to:

1. Exclude the report from my project to stop the build errors
2. Clean & rebuild my project
3. Refresh the Data Sources pane & confirm I could see the new fields
4. Re-include the report and open the report designer with the Data Sources pane pinned in view
5. (This is the key) Drag one of the new fields anywhere onto the report surface

Number 5 forced the report's internal XML copy of the data definition to refresh. Immediately after that, I could build again.

You'll need to learn how to use sed http://unixhelp.ed.ac.uk/CGI/man-cgi?sed

And also to use for so you can loop through your file entries http://www.cyberciti.biz/faq/bash-for-loop/

Here's the code to implement java comparable interface,

// adding implements comparable to class declaration
public class Animal implements Comparable<Animal>
{
    public String name;
    public int yearDiscovered;
    public String population;

    public Animal(String name, int yearDiscovered, String population)
    {
        this.name = name;
        this.yearDiscovered = yearDiscovered;
        this.population = population; 
    }

    public String toString()
    {
        String s = "Animal name : " + name + "\nYear Discovered : " + yearDiscovered + "\nPopulation: " + population;
        return s;
    }

    @Override
    public int compareTo(Animal other)  // compareTo method performs the comparisons 
    {
        return Integer.compare(this.year_discovered, other.year_discovered);
    }
}

In order to completely set the background to a given color :

1) set first the background color

2) call method "Clear(0,0,this.getWidth(),this.getHeight())" (width and height of the component paint area)

I think it is the basic procedure to set the background... I've had the same problem.

Another usefull hint : if you want to draw BUT NOT in a specific zone (something like a mask or a "hole"), call the setClip() method of the graphics with the "hole" shape (any shape) and then call the Clear() method (background should previously be set to the "hole" color).

You can make more complicated clip zones by calling method clip() (any times you want) AFTER calling method setClip() to have intersections of clipping shapes.

I didn't find any method for unions or inversions of clip zones, only intersections, too bad...

Hope it helps

In a simple way COALESCE :- is only for decreases the no of partitions , No shuffling of data it just compress the partitions

REPARTITION:- is for both increase and decrease the no of partitions , But shuffling takes place

Example:-

val rdd = sc.textFile("path",7)
rdd.repartition(10)
rdd.repartition(2)

Both works fine

But we go generally for this two things when we need to see output in one cluster,we go with this.

Simply add this

$id = ''; 
if( isset( $_GET['id'])) {
    $id = $_GET['id']; 
} 

You can try this:

HTML

<table>
    <tr>
        <td class="shrink">element1</td>
        <td class="shrink">data</td>
        <td class="shrink">junk here</td>
        <td class="expand">last column</td>
    </tr>
    <tr>
        <td class="shrink">elem</td>
        <td class="shrink">more data</td>
        <td class="shrink">other stuff</td>
        <td class="expand">again, last column</td>
    </tr>
    <tr>
        <td class="shrink">more</td>
        <td class="shrink">of </td>
        <td class="shrink">these</td>
        <td class="expand">rows</td>
    </tr>

Try to bump that value up!

This issue happens when you renamed your solution and the .net framework cannot find the old solution.

To resolve this, you need to find and replace the old name of solution and all dependencies on it with the new name. If you need to browse the physical file through file explorer do so.

The files that are normally affected are AssemblyInfo.cs, .sln an Properties > Application > Assembly name and Default namespace. Make sure to update them with the new name.

Open the file explorer, if the folder with the old name still exists, you need to delete it. Then clean and build the solution until the error is gone. (If needed clean and build the project one by one especially the affected project.)

For creating a console-based UI, you can use gui.cs. It is open-source (from Miguel de Icaza, creator of Xamarin), and runs on .NET Core on Windows, Linux, and macOS.

It has the following components:

• Buttons
• Labels
• Text entry
• Text view
• Time editing field
• Radio buttons
• Checkboxes
• Dialog boxes
  • Message boxes
• Windows
• Menus
• ListViews
• Frames
• ProgressBars
• Scroll views and Scrollbars
• Hexadecimal viewer/editor (HexView)

I think the blow code will help you, and add those code before setContentView()

getWindow().setFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS, WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);

Add those code behind setContentView() getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE);

Other than what Alex and Evan have already stated, I would like to add that a C++ struct is not like a C struct.

In C++, a struct can have methods, inheritance, etc. just like a C++ class.

Databases all the way.

However, if you still have a need for storing files, don't have the capacity to take on a new RDBMS (like Oracle, SQLServer, etc), than look into XML.

XML is a structure file format which offers you the ability to store things as a file but give you query power over the file and data within it. XML Files are easier to read than flat files and can be easily transformed applying an XSLT for even better human-readability. XML is also a great way to transport data around if you must.

I strongly suggest a DB, but if you can't go that route, XML is an ok second.

You have to call DataReader.Read to fetch the result:

SqlDataReader dr = cmd10.ExecuteReader();
if (dr.Read()) 
{
    // read data for first record here
}

DataReader.Read() returns a bool indicating if there are more blocks of data to read, so if you have more than 1 result, you can do:

while (dr.Read()) 
{
    // read data for each record here
}

Since C++11 it can be done inside a class with constexpr.

class stat {
    public:
        // init inside class
        static constexpr double inlineStaticVar = 22;
};

The variable can now be accessed with:

stat::inlineStaticVar

This problem occurs when the controller or directive are not specified as a array of dependencies and function. For example

angular.module("appName").directive('directiveName', function () {
    return {
        restrict: 'AE',
        templateUrl: 'calender.html',
        controller: function ($scope) {
            $scope.selectThisOption = function () {
                // some code
            };
        }
    };
});

When minified The '$scope' passed to the controller function is replaced by a single letter variable name . This will render angular clueless of the dependency . To avoid this pass the dependency name along with the function as a array.

angular.module("appName").directive('directiveName', function () {
    return {
        restrict: 'AE',
        templateUrl: 'calender.html'
        controller: ['$scope', function ($scope) { //<-- difference
            $scope.selectThisOption = function () {
                // some code
            };
        }]
    };
});

I was able to use Find & Replace with the "Find what:" input field set to:

" * "

(space asterisk space with no double-quotes)

and "Replace with:" set to:

""

(nothing)

I am assuming you know the length of the part before the _ and after the underscore, as well as the extension. If you don't it might be more complex than a simple substring.

cd C:\path\to\the\files
for /f %%a IN ('dir /b *.jpg') do (
set p=%a:~0,3%
set q=%a:~4,4%
set b=%p_%q.jpg
ren %a %b
)

I just came up with this script, and I did not test it. Check out this and that for more info.

IF you want to assume you don't know the positions of the _ and the lengths and the extension, I think you could do something with for loops to check the index of the _, then the last index of the ., wrap it in a goto thing and make it work. If you're willing to go through that trouble, I'd suggest you use WindowsPowerShell (or Cygwin) at least (for your own sake) or install a more advanced scripting language (think Python/Perl) you'll get more support either way.

Playing an audio file ensures full background Javascript performance for the time being

For me, it was the simplest and least intrusive solution - apart from playing a faint / almost-empty sound, there are no other potential side effects

You can find the details here: https://stackoverflow.com/a/51191818/914546

(From other answers, I see that some people use different properties of the Audio tag, I do wonder whether it's possible to use the Audio tag for full performance, without actually playing something)

There is no way to display interactive elements on the lockscreen or wallpaper with a non jailbroken iPhone.

I would recommend Countdown Widget it's free an you can display countdowns in the notification center which you can also access from your lockscreen.

  SELECT * INTO newtable FROM oldtable where 1=2

Where 1=2 is used when you need to copy the complete structure of a table without copying the data.

 SELECT * INTO newtable FROM oldtable 

To create a table with data you can use this statement.

In Windows Command Line (cmd), you can mount the current directory like so:

docker run --rm -it -v %cd%:/usr/src/project gcc:4.9

In PowerShell, you use ${PWD}, which gives you the current directory:

docker run --rm -it -v ${PWD}:/usr/src/project gcc:4.9

On Linux:

docker run --rm -it -v $(pwd):/usr/src/project gcc:4.9

Cross Platform

The following options will work on both PowerShell and on Linux (at least Ubuntu):

docker run --rm -it -v ${PWD}:/usr/src/project gcc:4.9
docker run --rm -it -v $(pwd):/usr/src/project gcc:4.9

You can use date to get time and date of a day:

[pengyu@GLaDOS ~]$date
Tue Aug 27 15:01:27 CST 2013

Also hwclock would do:

[pengyu@GLaDOS ~]$hwclock
Tue 27 Aug 2013 03:01:29 PM CST  -0.516080 seconds

For customized output, you can either redirect the output of date to something like awk, or write your own program to do that.

Remember to put your own executable scripts/binary into your PATH (e.g. /usr/bin) to make it invokable anywhere.

Try using raw_input rather than input if you simply want to read strings.

print("Enter your name: ")
x = raw_input()
print("Hello, "+x)

open your git command line

this command on command line and change email address put your own email which those use creating accout for github

hit enter

put git config --global user.name "Your Name"

use your own name insted of your name

hit enter

No one mentions anything about the --single-transaction option. People should use it by default for InnoDB tables to ensure data consistency. In this case:

mysqldump --single-transaction -h [remoteserver.com] -u [username] -p [password] [yourdatabase] > [dump_file.sql]

This makes sure the dump is run in a single transaction that's isolated from the others, preventing backup of a partial transaction.

For instance, consider you have a game server where people can purchase gears with their account credits. There are essentially 2 operations against the database:

1. Deduct the amount from their credits
2. Add the gear to their arsenal

Now if the dump happens in between these operations, the next time you restore the backup would result in the user losing the purchased item, because the second operation isn't dumped in the SQL dump file.

While it's just an option, there are basically not much of a reason why you don't use this option with mysqldump.

This can happen because java script allows white spaces sometimes if a string is concatenated with a number. try removing the spaces and create a string and then pass it into getElementById.

example:

var str = 'horseThumb_'+id;

str = str.replace(/^\s+|\s+$/g,"");

function AddBorder(id){

    document.getElementById(str).className='hand positionLeft'

}

var element = //the DOM element to listen for the key on.
element.onkeyup = function(e) {
   if(e.metaKey) {
      //command key was pressed
   }
}

this isn't a css selector. you can avoid spelling the id of this by passing it as a context:

$('option:selected', this).remove();

sort sorts inplace so returns nothing:

In [54]:
df = pd.DataFrame({'A':[1,1,3,2,6,2,8]})
a = df['A'].unique()
a.sort()
a

Out[54]:
array([1, 2, 3, 6, 8], dtype=int64)

So you have to call print a again after the call to sort.

Eg.:

In [55]:
df = pd.DataFrame({'A':[1,1,3,2,6,2,8]})
a = df['A'].unique()
a.sort()
print(a)

[1 2 3 6 8]

The problem with opacity is that it will also affect the content, when often you do not want this to happen.

If you just want your element to be transparent, it's really as easy as :

background-color: transparent;

But if you want it to be in colors, you can use:

background-color: rgba(255, 0, 0, 0.4);

Or define a background image (1px by 1px) saved with the right alpha.
(To do so, use Gimp, Paint.Net or any other image software that allows you to do that.
Just create a new image, delete the background and put a semi-transparent color in it, then save it in png.)

As said by René, the best thing to do would be to mix both, with the rgba first and the 1px by 1px image as a fallback if the browser doesn't support alpha :

background: url('img/red_transparent_background.png');
background: rgba(255, 0, 0, 0.4);

Demo : My JSFiddle

ALTER TABLE your_table
ADD PRIMARY KEY (Drugid);

You start tomcat from some directory - which is the $cwd for tomcat. You can specify any path relative to this $cwd.

suppose you have

home
- tomcat
 |_bin
- cssStore
 |_file.css

And suppose you start tomcat from ~/tomcat, using the command "bin/startup.sh".

~/tomcat becomes the home directory ($cwd) for tomcat

You can access "../cssStore/file.css" from class files in your servlet now

Hope that helps, - M.S.

Please Try to pass parameters in httpoptions, you can follow function below

deleteAction(url, data) {
    const authToken = sessionStorage.getItem('authtoken');
    const options = {
      headers: new HttpHeaders({
        'Content-Type': 'application/json',
        Authorization: 'Bearer ' + authToken,
      }),
      body: data,
    };
    return this.client.delete(url, options);
  }

Also, if your PATH's dir is enclosed in quotes, it will work from the command prompt but you'll get the same error message

I.e. this causes an issue with Process.Start() not finding your exe:

PATH="C:\my program\bin";c:\windows\system32

Maybe it helps someone.

For me I had indicated max-height instead of max-width.

If that is you, go change it !

    @media screen and (max-width: 350px) {    // Not max-height
        .letter{
            font-size:20px;
        }
    }

Yes it is wise to use a version control system for your project. Anyway, focusing on your installation warning issue you can try to launch npm install command starting from your root project folder instead of outside of it, so the installation steps will only update the existing package-lock.json file instead of creating a new one. Hope this helps.

Sure:

public HttpResponseMessage Post()
{
    // ... do the job

    // now redirect
    var response = Request.CreateResponse(HttpStatusCode.Moved);
    response.Headers.Location = new Uri("http://www.abcmvc.com");
    return response;
}

Use IsNumeric Function :

IsNumeric(number)

If you want to validate a phone number you should use a regular expression, for example:

^\(?([0-9]{3})\)?[-. ]?([0-9]{3})[-. ]?([0-9]{3})$

select * from this_table;

select distinct person from this_table

union select address as location from that_table 

drop wrong_table from this_database;

Here is an excerpts from "Effective Python: 90 Specific Ways to Write Better Python" (Amazing book. I highly recommend it).

Things to Remember

? Define new class interfaces using simple public attributes and avoid defining setter and getter methods.

? Use @property to define special behavior when attributes are accessed on your objects, if necessary.

? Follow the rule of least surprise and avoid odd side effects in your @property methods.

? Ensure that @property methods are fast; for slow or complex work—especially involving I/O or causing side effects—use normal methods instead.

One advanced but common use of @property is transitioning what was once a simple numerical attribute into an on-the-fly calculation. This is extremely helpful because it lets you migrate all existing usage of a class to have new behaviors without requiring any of the call sites to be rewritten (which is especially important if there’s calling code that you don’t control). @property also provides an important stopgap for improving interfaces over time.

I especially like @property because it lets you make incremental progress toward a better data model over time.
@property is a tool to help you address problems you’ll come across in real-world code. Don’t overuse it. When you find yourself repeatedly extending @property methods, it’s probably time to refactor your class instead of further paving over your code’s poor design.

? Use @property to give existing instance attributes new functionality.

? Make incremental progress toward better data models by using @property.

? Consider refactoring a class and all call sites when you find yourself using @property too heavily.

An enum is like a Singleton. The JVM creates the instance.

If you would create it by yourself with classes it could be look like that

public static class MyEnum {

    final public static MyEnum ONE;
    final public static MyEnum TWO;

    static {
        ONE = new MyEnum("1");
        TWO = new MyEnum("2");
    }

    final String enumValue;

    private MyEnum(String value){
        enumValue = value;    
    }

    @Override
    public String toString(){
        return enumValue;
    }


}

And could be used like that:

public class HelloWorld{

   public static class MyEnum {

       final public static MyEnum ONE;
       final public static MyEnum TWO;

       static {
          ONE = new MyEnum("1");
          TWO = new MyEnum("2");
       }

       final String enumValue;

       private MyEnum(String value){
           enumValue = value;    
       }

       @Override
       public String toString(){
           return enumValue;
       }


   }

    public static void main(String []args){

       System.out.println(MyEnum.ONE);
       System.out.println(MyEnum.TWO);

       System.out.println(MyEnum.ONE == MyEnum.ONE);

       System.out.println("Hello World");
    }
}

The zero value for time.Time is 0001-01-01 00:00:00 +0000 UTC See http://play.golang.org/p/vTidOlmb9P

From xaml code you can call a predefined SystemCommand:

Command="SystemCommands.MinimizeWindowCommand"

I think this should be the prefered way...

The above error can occur for multiple cases during servlet startup / request. Hope you check the full stack trace of the server log, If you have tomcat, you can also see the exact causes in html preview of the 500 Internal Server Error page.

Weird thing is, if you try to hit the request url a second time, you would get 404 Not Found page.

You can also debug this issue, by placing breakpoints on all the classes constructor initialization block, whose objects are created during servlet startup/request.

In my case, I didn't had javaassist jar loaded for the Weld CDI injection to work. And it shown NoClassDefFound Error.

for the sake of completeness, you could use:

(DT_STR,8, 1252) (YEAR(GetDate()) * 10000 + MONTH(GetDate()) * 100 + DAY(GetDate()))

for YYYYMMDD or

RIGHT("000000" + (DT_STR,8, 1252) (DAY(GetDate()) * 1000000 + MONTH(GetDate()) * 10000 + YEAR(GetDate())), 8)

for DDMMYYYY (without hyphens). If you want / need the date as integer (e.g. for _key-columns in DWHs), just remove the DT_STR / RIGTH function and do just the math.

Declaration of new variables in case statements is what causing problems. Enclosing all case statements in {} will limit the scope of newly declared variables to the currently executing case which solves the problem.

switch(choice)
{
    case 1: {
       // .......
    }break;
    case 2: {
       // .......
    }break;
    case 3: {
       // .......
    }break;
}    

If you're creating a framework the whole idea is to make it portable. Tying a framework to the app delegate defeats the purpose of building a framework. What is it you need the app delegate for?

If a non-static method is member of a class, you have to define it like that:

def Method(self, atributes..)

So, I suppose your 'e' is instance of some class with implemented method that tries to execute and has too much arguments.

var empty = $("#cartContent").html().trim().length == 0;

(answer suitable for a subset of users)

If you're on (any recent) macOS, and even if you're away from your Time Machine disk, the OS will have saved hourly backups, called local snapshots.

Enter Time Machine and navigate to the file you lost. The OS will then ask you:

The location to which you're restoring "file.ext" already contains an
item with the same name. Do you want to replace it with the one you're
restoring?

You should be able to recover the file(s) you lost.

Sometimes we have more than one net interface.

A simple method to find out the mac address of a specific interface, is:

def getmac(interface):

  try:
    mac = open('/sys/class/net/'+interface+'/address').readline()
  except:
    mac = "00:00:00:00:00:00"

  return mac[0:17]

to call the method is simple

myMAC = getmac("wlan0")

I have found an FTP server and its working. I was successfully able to upload a file to this FTP server and then see file created by hitting same url. Visit here and read properly before use. Good luck...!

Edit: link is now dead, but the FTP server is still up! Connect with the username "anonymous" and an email address as a password: ftp://ftp.swfwmd.state.fl.us

BUT FIRST read this before using it

More an example:

$galleryIds = [1, '2', 'Vitruvian Man'];
$ids = array_filter($galleryIds, function($n){return (is_numeric($n));});
$ids = implode(', ', $ids);

$sql = "SELECT * FROM galleries WHERE id IN ({$ids})";
// output: 'SELECT * FROM galleries WHERE id IN (1, 2)'

$statement = $pdo->prepare($sql);
$statement->execute();

Yes, you can!

$str = 'One';
$class = 'Class'.$str;
$object = new $class();

When using namespaces, supply the fully qualified name:

$class = '\Foo\Bar\MyClass'; 
$instance = new $class();

Other cool stuff you can do in php are:
Variable variables:

$personCount = 123;
$varname = 'personCount';
echo $$varname; // echo's 123

And variable functions & methods.

$func = 'my_function';
$func('param1'); // calls my_function('param1');

$method = 'doStuff';
$object = new MyClass();
$object->$method(); // calls the MyClass->doStuff() method. 

Yes, we can zip and unzip the file/folder using cmd. See the below command and simply you can copy past in cmd and change the directory and file name

To Zip/Compress File
powershell Compress-Archive D:\Build\FolderName D:\Build\FolderName.zip

To Unzip/Expand File
powershell expand-archive D:\Build\FileName.zip D:\deployments\FileName

The code of JS20'07'11 is really incredible simple and direct. One suggestion that I would like to give is to put a exclamation mark in the conditions:

InStr(1, objName.RefersTo, sWsName+"!", vbTextCompare)

Because this will prevent adding a NamedRange in an incorrect Sheet. Eg: If the NamedRange refers to a Sheet named Plan11 and you have another Sheet named Plan1 the code can do some mess when add the ranges if you don't use the exclamation mark.

UPDATE

A correction: It's best to use a regular expression evaluate the name of the Sheet. A simple function that you can use is the following (adapted by http://blog.malcolmp.com/2010/regular-expressions-excel-add-in, enable Microsoft VBScript Regular Expressions 5.5):

Function xMatch(pattern As String, searchText As String, Optional matchIndex As Integer = 1, Optional ignoreCase As Boolean = True) As String
On Error Resume Next
Dim RegEx As New RegExp
RegEx.Global = True
RegEx.MultiLine = True
RegEx.pattern = pattern
RegEx.ignoreCase = ignoreCase
Dim matches As MatchCollection
Set matches = RegEx.Execute(searchText)
Dim i As Integer
i = 1
For Each Match In matches
    If i = matchIndex Then
        xMatch = Match.Value
    End If
    i = i + 1
Next
End Function

So, You can use something like that:

xMatch("'?" +sWsName + "'?" + "!", objName.RefersTo, 1) <> ""

instead of

InStr(1, objName.RefersTo, sWsName+"!", vbTextCompare)

This will cover Plan1 and 'Plan1' (when the range refers to more than one cell) variations

TIP: Avoid Sheet names with single quotes ('), :) .

Numpy's histogram function returns the edges of each bin, rather than the value of the bin. This makes sense for floating-point numbers, which can lie within an interval, but may not be the desired result when dealing with discrete values or integers (0, 1, 2, etc). In particular, the length of bins returned from np.histogram is not equal to the length of the counts / density.

To get around this, I used np.digitize to quantize the input, and count the fraction of counts for each bin. You could easily edit to get the integer number of counts.

def compute_PMF(data):
    import numpy as np
    from collections import Counter
    _, bins = np.histogram(data, bins='auto', range=(data.min(), data.max()), density=False)
    h = Counter(np.digitize(data,bins) - 1)
    weights = np.asarray(list(h.values())) 
    weights = weights / weights.sum()
    values = np.asarray(list(h.keys()))
    return weights, values

I notice that you mention a function %like% in your current approach. I don't know if that's a reference to the %like% from "data.table", but if it is, you can definitely use it as follows.

Note that the object does not have to be a data.table (but also remember that subsetting approaches for data.frames and data.tables are not identical):

library(data.table)
mtcars[rownames(mtcars) %like% "Merc", ]
iris[iris$Species %like% "osa", ]

If that is what you had, then perhaps you had just mixed up row and column positions for subsetting data.

If you don't want to load a package, you can try using grep() to search for the string you're matching. Here's an example with the mtcars dataset, where we are matching all rows where the row names includes "Merc":

mtcars[grep("Merc", rownames(mtcars)), ]
             mpg cyl  disp  hp drat   wt qsec vs am gear carb
# Merc 240D   24.4   4 146.7  62 3.69 3.19 20.0  1  0    4    2
# Merc 230    22.8   4 140.8  95 3.92 3.15 22.9  1  0    4    2
# Merc 280    19.2   6 167.6 123 3.92 3.44 18.3  1  0    4    4
# Merc 280C   17.8   6 167.6 123 3.92 3.44 18.9  1  0    4    4
# Merc 450SE  16.4   8 275.8 180 3.07 4.07 17.4  0  0    3    3
# Merc 450SL  17.3   8 275.8 180 3.07 3.73 17.6  0  0    3    3
# Merc 450SLC 15.2   8 275.8 180 3.07 3.78 18.0  0  0    3    3

And, another example, using the iris dataset searching for the string osa:

irisSubset <- iris[grep("osa", iris$Species), ]
head(irisSubset)
#   Sepal.Length Sepal.Width Petal.Length Petal.Width Species
# 1          5.1         3.5          1.4         0.2  setosa
# 2          4.9         3.0          1.4         0.2  setosa
# 3          4.7         3.2          1.3         0.2  setosa
# 4          4.6         3.1          1.5         0.2  setosa
# 5          5.0         3.6          1.4         0.2  setosa
# 6          5.4         3.9          1.7         0.4  setosa

For your problem try:

selectedRows <- conservedData[grep("hsa-", conservedData$miRNA), ]

In PostgreSQL, to get the average of multiple (2 to 8) columns in one row just define a set of seven functions called average(). Will produce the average of the non-null columns.

And then just

Correction for What does it mean to bind a multicast (udp) socket? as long as it partially true at the following quote:

The "bind" operation is basically saying, "use this local UDP port for sending and receiving data. In other words, it allocates that UDP port for exclusive use for your application

There is one exception. Multiple applications can share the same port for listening (usually it has practical value for multicast datagrams), if the SO_REUSEADDR option applied. For example

int sock = socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP); // create UDP socket somehow
...
int set_option_on = 1;
// it is important to do "reuse address" before bind, not after
int res = setsockopt(sock, SOL_SOCKET, SO_REUSEADDR, (char*) &set_option_on, 
    sizeof(set_option_on));
res = bind(sock, src_addr, len);

If several processes did such "reuse binding", then every UDP datagram received on that shared port will be delivered to each of the processes (providing natural joint with multicasts traffic).

Here are further details regarding what happens in a few cases:

1. attempt of any bind ("exclusive" or "reuse") to free port will be successful

2. attempt to "exclusive binding" will fail if the port is already "reuse-binded"

3. attempt to "reuse binding" will fail if some process keeps "exclusive binding"

This is what worked for me. Tried everything else with no luck:

<html>

  <head>
    <title>Example: Change event on a select</title>

    <script type="text/javascript">

      function changeEventHandler(event) {
        alert('You like ' + event.target.value + ' ice cream.');
      }

    </script>

  </head>

  <body>
    <label>Choose an ice cream flavor: </label>
    <select size="1" onchange="changeEventHandler(event);">
      <option>chocolate</option>
      <option>strawberry</option>
      <option>vanilla</option>
    </select>
  </body>

</html>

Taken from Mozilla

The .title() method won't work in all test cases, so using .capitalize(), .replace() and .split() together is the best choice to capitalize the first letter of each word.

eg: def caps(y):

     k=y.split()
     for i in k:
        y=y.replace(i,i.capitalize())
     return y

from selenium import webdriver

PROXY = "23.23.23.23:3128" # IP:PORT or HOST:PORT

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--proxy-server=%s' % PROXY)

chrome = webdriver.Chrome(options=chrome_options)
chrome.get("http://whatismyipaddress.com")

Are you trying to make it responsive? If you are then I would just recommend the following:

.tales {
  width: 100%;
}
.carousel-inner{
  width:100%;
  max-height: 200px !important;
}

However, the best way to handle this responsively would be thru the use of media queries like such:

/* Smaller than standard 960 (devices and browsers) */
@media only screen and (max-width: 959px) {}

/* Tablet Portrait size to standard 960 (devices and browsers) */
@media only screen and (min-width: 768px) and (max-width: 959px) {}

/* All Mobile Sizes (devices and browser) */
@media only screen and (max-width: 767px) {}

/* Mobile Landscape Size to Tablet Portrait (devices and browsers) */
@media only screen and (min-width: 480px) and (max-width: 767px) {}

/* Mobile Portrait Size to Mobile Landscape Size (devices and browsers) */
@media only screen and (max-width: 479px) {}

Splice - MDN reference - ECMA-262 spec

Syntax
array.splice(start[, deleteCount[, item1[, item2[, ...]]]])

Parameters

• start: required. Initial index.
  If start is negative it is treated as "Math.max((array.length + start), 0)" as per spec (example provided below) effectively from the end of array.
• deleteCount: optional. Number of elements to be removed (all from start if not provided).
• item1, item2, ...: optional. Elements to be added to the array from start index.

Returns: An array with deleted elements (empty array if none removed)

Mutate original array: Yes

Examples:

const array = [1,2,3,4,5];

// Remove first element
console.log('Elements deleted:', array.splice(0, 1), 'mutated array:', array);
// Elements deleted: [ 1 ] mutated array: [ 2, 3, 4, 5 ]

// array = [ 2, 3, 4, 5]
// Remove last element (start -> array.length+start = 3)
console.log('Elements deleted:', array.splice(-1, 1), 'mutated array:', array);
// Elements deleted: [ 5 ] mutated array: [ 2, 3, 4 ]

More examples in MDN Splice examples

Slice - MDN reference - ECMA-262 spec

Syntax
array.slice([begin[, end]])
Parameters

• begin: optional. Initial index (default 0).
  If begin is negative it is treated as "Math.max((array.length + begin), 0)" as per spec (example provided below) effectively from the end of array.
• end: optional. Last index for extraction but not including (default array.length). If end is negative it is treated as "Math.max((array.length + begin),0)" as per spec (example provided below) effectively from the end of array.

Returns: An array containing the extracted elements.

Mutate original: No

Examples:

const array = [1,2,3,4,5];

// Extract first element
console.log('Elements extracted:', array.slice(0, 1), 'array:', array);
// Elements extracted: [ 1 ] array: [ 1, 2, 3, 4, 5 ]

// Extract last element (start -> array.length+start = 4)
console.log('Elements extracted:', array.slice(-1), 'array:', array);
// Elements extracted: [ 5 ] array: [ 1, 2, 3, 4, 5 ]

Performance comparison

Don't take this as absolute truth as depending on each scenario one might be performant than the other.
Performance test

The answer is in this line of the output of readelf -a in the original question

  [Requesting program interpreter: /lib/ld-linux.so.2]

I was missing the /lib/ld-linux.so.2 file, which is needed to run 32-bit apps. The Ubuntu package that has this file is libc6-i386.

Just to offer some variety, the comma operator can be used too but some might say "noooooo!", but it works:

<input type="button" onclick="one(), two(), three(), four()"/>

http://jsbin.com/oqizir/1/edit

here is solution, i create a text field to dynamic add new items in array my html code is

 <input type="text" id="name">_x000D_
  <input type="button" id="btn" value="Button">_x000D_
  <div id="names">_x000D_
  </div>

now type any thing in text field and click on button this will add item onto array and call function dispaly_arry

$(document).ready(function()_x000D_
{  _x000D_
 function display_array()_x000D_
 {_x000D_
  $("#names").text('');_x000D_
  $.each(names,function(index,value)_x000D_
  {_x000D_
    $('#names').append(value + '<br/>');_x000D_
  });_x000D_
 }_x000D_
 _x000D_
 var names = ['Alex','Billi','Dale'];_x000D_
 display_array();_x000D_
 $('#btn').click(function()_x000D_
 {_x000D_
  var name = $('#name').val();_x000D_
  names.push(name);// appending value to arry _x000D_
  display_array();_x000D_
  _x000D_
 });_x000D_
 _x000D_
});_x000D_
 

showing array elements into div , you can use span but for this solution use same id .!

In package.json, add something like (This version is ok for Angular 2):

  "ngx-order-pipe": "^1.1.3",

In your typescript module (and imports array):

  import { OrderModule } from 'ngx-order-pipe';

You can't do without transaction logs in SQL Server, under any circumstances. The engine simply won't function.

You CAN set your recovery model to SIMPLE on your dev machines - that will prevent transaction log bloating when tran log backups aren't done.

ALTER DATABASE MyDB SET RECOVERY SIMPLE;

Here is a solution which uses a class (never instantiated) to hold data. I like that this way involves very little typing and does not require any additional packages etc.

class myStruct:
    field1 = "one"
    field2 = "2"

You can add more fields later, as needed:

myStruct.field3 = 3

To get the values, the fields are accessed as usual:

>>> myStruct.field1
'one'

to_string() is only present in c++11 so if c++ version is less use some alternate methods such as sprintf or ostringstream

setTimeout is a kind of Thread, it holds a operation for a given time and execute.

setTimeout(function,time_in_mills);

in here the first argument should be a function type; as an example if you want to print your name after 3 seconds, your code should be something like below.

setTimeout(function(){console.log('your name')},3000);

Key point to remember is, what ever you want to do by using the setTimeout method, do it inside a function. If you want to call some other method by parsing some parameters, your code should look like below:

setTimeout(function(){yourOtherMethod(parameter);},3000);

compileSdkVersion

The compileSdkVersion is the version of the API the app is compiled against. This means you can use Android API features included in that version of the API (as well as all previous versions, obviously). If you try and use API 16 features but set compileSdkVersion to 15, you will get a compilation error. If you set compileSdkVersion to 16 you can still run the app on a API 15 device as long as your app's execution paths do not attempt to invoke any APIs specific to API 16.

targetSdkVersion

The targetSdkVersion has nothing to do with how your app is compiled or what APIs you can utilize. The targetSdkVersion is supposed to indicate that you have tested your app on (presumably up to and including) the version you specify. This is more like a certification or sign off you are giving the Android OS as a hint to how it should handle your app in terms of OS features.

For example, as the documentation states:

For example, setting this value to "11" or higher allows the system to apply a new default theme (Holo) to your app when running on Android 3.0 or higher...

The Android OS, at runtime, may change how your app is stylized or otherwise executed in the context of the OS based on this value. There are a few other known examples that are influenced by this value and that list is likely to only increase over time.

For all practical purposes, most apps are going to want to set targetSdkVersion to the latest released version of the API. This will ensure your app looks as good as possible on the most recent Android devices. If you do not specify the targetSdkVersion, it defaults to the minSdkVersion.

If this need to be done in UIBarButtonItem, additional wrapping in view should be used
This will work

let view = UIView()
let button = UIButton()
button.setTitle("Skip", for: .normal)
button.setImage(#imageLiteral(resourceName:"forward_button"), for: .normal)
button.semanticContentAttribute = .forceRightToLeft
button.sizeToFit()
view.addSubview(button)
view.frame = button.bounds
navigationItem.rightBarButtonItem = UIBarButtonItem(customView: view)

This won't work

let button = UIButton()
button.setTitle("Skip", for: .normal)
button.setImage(#imageLiteral(resourceName:"forward_button"), for: .normal)
button.semanticContentAttribute = .forceRightToLeft
button.sizeToFit()
navigationItem.rightBarButtonItem = UIBarButtonItem(customView: button)

You can create a search variable to hold your searching criteria. Here is an example using database.

 var query = from o in this.mJDBDataset.Products 
             where o.ProductStatus == textBox1.Text || o.Karrot == textBox1.Text 
             || o.ProductDetails == textBox1.Text || o.DepositDate == textBox1.Text 
             || o.SellDate == textBox1.Text
             select o;

 dataGridView1.DataSource = query.ToList();

 //Search and Calculate
 search = textBox1.Text;
 cnn.Open();
 string query1 = string.Format("select * from Products where ProductStatus='"
               + search +"'");
 SqlDataAdapter da = new SqlDataAdapter(query1, cnn);
 DataSet ds = new DataSet();
 da.Fill(ds, "Products");
 SqlDataReader reader;
 reader = new SqlCommand(query1, cnn).ExecuteReader();

 List<double> DuePayment = new List<double>();

 if (reader.HasRows)
 {

  while (reader.Read())
  {

   foreach (DataRow row in ds.Tables["Products"].Rows)
   {

     DuePaymentstring.Add(row["DuePayment"].ToString());
     DuePayment = DuePaymentstring.Select(x => double.Parse(x)).ToList();

   }
  }

  tdp = 0;
  tdp = DuePayment.Sum();                        
  DuePaymentstring.Remove(Convert.ToString(DuePaymentstring.Count));
  DuePayment.Clear();
 }
 cnn.Close();
 label3.Text = Convert.ToString(tdp + " Due Payment Count: " + 
 DuePayment.Count + " Due Payment string Count: " + DuePaymentstring.Count);
 tdp = 0;
 //DuePaymentstring.RemoveRange(0,DuePaymentstring.Count);
 //DuePayment.RemoveRange(0, DuePayment.Count);
 //Search and Calculate

Here "var query" is generating the search criteria you are giving through the search variable. Then "DuePaymentstring.Select" is selecting the data matching your given criteria. Feel free to ask if you have problem understanding.

I run into the same problem and wrote a little shared-memory utility class to work around it.

I'm using multiprocessing.RawArray (lockfree), and also the access to the arrays is not synchronized at all (lockfree), be careful not to shoot your own feet.

With the solution I get speedups by a factor of approx 3 on a quad-core i7.

Here's the code: Feel free to use and improve it, and please report back any bugs.

    print("Sequential: ", t1.timeit(number=1))    
    print("Parallel: ", t2.timeit(number=1))

Another more versatile way is to use find:

sed -i 's/asd/dsg/g' $(find . -type f -name 'xa*')

document.getElementById('Id').value='new value';

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

+ this happens because sql sometimes doesn't recognize dd/mm/yyyy format
+ so we should always check if the input string is a valid date or not and the accordingly convert it to mm/dd/yyyy and so , i have shown below how it can be done, i have created a function to rearrange in mm/dd/yyyy from dd/mm/yyyy

select case when isdate('yourdate')=1 then CAST('yourdate' AS datetime) 
  else (select * from dbo.fn_convertdate(yourdate))

Create function dbo.fn_convertdate( @Stringdate nvarchar(29))
RETURNS @output TABLE(splitdata NVARCHAR(MAX) 
)
Begin
Declare @table table(id int identity(1,1), data varchar(255))
Declare @firstpart nvarchar(255)
Declare @tableout table(id int identity(1,1), data varchar(255))

Declare @Secondpart nvarchar(255)
Declare @Thirdpart nvarchar(255)

declare @date datetime

insert into @table
select * from dbo.fnSplitString(@Stringdate,'/')
select @firstpart=data from @table where id=2
select @Secondpart=data from @table where id=1
select @Thirdpart=data from @table where id=3
set @date=@firstpart+'/'+@Secondpart+'/'+@Thirdpart
insert into @output(splitdata) values(
@date)


return
End

Update query may have some issues

$query = "UPDATE anstalld SET mandag = '$mandag', tisdag = '$tisdag', onsdag = '$onsdag', torsdag = '$torsdag', fredag = '$fredag' WHERE namn = '$namn' ";
echo $query;

Please make sure that, your variable not having values with qoutes ( ' ), May be the query is breaking somewhere.

echo the query and try to execute in phpmyadmin itself. Then you can find the issues.

A slightly less verbose way is to use the performSelector: withObject: afterDelay: which sets up the NSTimer object for you and can be easily cancelled

So continuing with the previous example this would be

[self performSelector:@selector(goToSecondButton) withObject:nil afterDelay:.06];

I have also faced the same issue while installing the XAMPP. The reason being the port 80 as configured in httpd.conf is already in use in other application (eg., in Skype). You can change the port value in httpd.conf to 8080 or other number. Click on config icon and open http.conf file. Search for 80 and do the following steps

In httpd.conf change
Listen 80 to Listen 8080
and
ServerName localhost:80 to
ServerName localhost:8080

You can check the ports used currently by clicking on netstatt icon in the XAMPP Control Panel

.NET compact framework has been ported to Symbian OS (http://www.redfivelabs.com/). If .NET as a 'closed' platform can be ported to this platform, I can't see any reason why it cannot be done for Android.

I think you are looking for the Dictionary object, found in the Microsoft Scripting Runtime library. (Add a reference to your project from the Tools...References menu in the VBE.)

It pretty much works with any simple value that can fit in a variant (Keys can't be arrays, and trying to make them objects doesn't make much sense. See comment from @Nile below.):

Dim d As dictionary
Set d = New dictionary

d("x") = 42
d(42) = "forty-two"
d(CVErr(xlErrValue)) = "Excel #VALUE!"
Set d(101) = New Collection

You can also use the VBA Collection object if your needs are simpler and you just want string keys.

I don't know if either actually hashes on anything, so you might want to dig further if you need hashtable-like performance. (EDIT: Scripting.Dictionary does use a hash table internally.)

Status of the issue, June 2014: Fixed with Chrome 37

Finally, the Chrome team will release a fix for this issue with Chrome 37 which will be released to public in July 2014. See example comparison of current stable Chrome 35 and latest Chrome 37 (early development preview) here:

Status of the issue, December 2013

1.) There is NO proper solution when loading fonts via @import, <link href= or Google's webfont.js. The problem is that Chrome simply requests .woff files from Google's API which render horribly. Surprisingly all other font file types render beautifully. However, there are some CSS tricks that will "smoothen" the rendered font a little bit, you'll find the workaround(s) deeper in this answer.

2.) There IS a real solution for this when self-hosting the fonts, first posted by Jaime Fernandez in another answer on this Stackoverflow page, which fixes this issue by loading web fonts in a special order. I would feel bad to simply copy his excellent answer, so please have a look there. There is also an (unproven) solution that recommends using only TTF/OTF fonts as they are now supported by nearly all browsers.

3.) The Google Chrome developer team works on that issue. As there have been several huge changes in the rendering engine there's obviously something in progress.

I've written a large blog post on that issue, feel free to have a look: How to fix the ugly font rendering in Google Chrome

Reproduceable examples

See how the example from the initial question look today, in Chrome 29:

POSITIVE EXAMPLE:

Left: Firefox 23, right: Chrome 29

POSITIVE EXAMPLE:

Top: Firefox 23, bottom: Chrome 29

NEGATIVE EXAMPLE: Chrome 30

NEGATIVE EXAMPLE: Chrome 29

Solution

Fixing the above screenshot with -webkit-text-stroke:

First row is default, second has:

-webkit-text-stroke: 0.3px;

Third row has:

-webkit-text-stroke: 0.6px;

So, the way to fix those fonts is simply giving them

-webkit-text-stroke: 0.Xpx;

or the RGBa syntax (by nezroy, found in the comments! Thanks!)

-webkit-text-stroke: 1px rgba(0,0,0,0.1)

There's also an outdated possibility: Give the text a simple (fake) shadow:

text-shadow: #fff 0px 1px 1px;

RGBa solution (found in Jasper Espejo's blog):

text-shadow: 0 0 1px rgba(51,51,51,0.2);

I made a blog post on this:

If you want to be updated on this issue, have a look on the according blog post: How to fix the ugly font rendering in Google Chrome. I'll post news if there're news on this.

My original answer:

This is a big bug in Google Chrome and the Google Chrome Team does know about this, see the official bug report here. Currently, in May 2013, even 11 months after the bug was reported, it's not solved. It's a strange thing that the only browser that messes up Google Webfonts is Google's own browser Chrome (!). But there's a simple workaround that will fix the problem, please see below for the solution.

STATEMENT FROM GOOGLE CHROME DEVELOPMENT TEAM, MAY 2013

Official statement in the bug report comments:

Our Windows font rendering is actively being worked on. ... We hope to have something within a milestone or two that developers can start playing with. How fast it goes to stable is, as always, all about how fast we can root out and burn down any regressions.

I think the only way to handle this is to use JavaScript

Try this Invert text color of a specific element

If you do this with css3 it's only compatible with the newest browser versions.

It is important to recognize that the copyright laws have changed and that for non-US sources, especially after the USA joining the Berne Convention on March 1, 1989, copyright registration in not necessary for enforcement of a copyright notice.
Here is a resumé quoted from the Cornell University Law School (copied on March 4, 2015 from https://www.law.cornell.edu/wex/copyright:

"Copyright copyright: an overview

The U.S. Copyright Act, 17 U.S.C. §§ 101 - 810, is Federal legislation enacted by Congress under its Constitutional grant of authority to protect the writings of authors. See U.S. Constitution, Article I, Section 8. Changing technology has led to an ever expanding understanding of the word "writings." The Copyright Act now reaches architectural design, software, the graphic arts, motion pictures, and sound recordings. See § 106. As of January 1, 1978, all works of authorship fixed in a tangible medium of expression and within the subject matter of copyright were deemed to fall within the exclusive jurisdiction of the Copyright Act regardless of whether the work was created before or after that date and whether published or unpublished. See § 301. See also preemption.

The owner of a copyright has the exclusive right to reproduce, distribute, perform, display, license, and to prepare derivative works based on the copyrighted work. See § 106. The exclusive rights of the copyright owner are subject to limitation by the doctrine of "fair use." See § 107. Fair use of a copyrighted work for purposes such as criticism, comment, news reporting, teaching, scholarship, or research is not copyright infringement. To determine whether or not a particular use qualifies as fair use, courts apply a multi-factor balancing test. See § 107.

Copyright protection subsists in original works of authorship fixed in any tangible medium of expression from which they can be perceived, reproduced, or otherwise communicated, either directly or with the aid of a machine or device. See § 102. Copyright protection does not extend to any idea, procedure, process, system, method of operation, concept, principle, or discovery. For example, if a book is written describing a new system of bookkeeping, copyright protection only extends to the author's description of the bookkeeping system; it does not protect the system itself. See Baker v. Selden, 101 U.S. 99 (1879).

According to the Copyright Act of 1976, registration of copyright is voluntary and may take place at any time during the term of protection. See § 408. Although registration of a work with the Copyright Office is not a precondition for protection, an action for copyright infringement may not be commenced until the copyright has been formally registered with the Copyright Office. See § 411.

Deposit of copies with the Copyright Office for use by the Library of Congress is a separate requirement from registration. Failure to comply with the deposit requirement within three months of publication of the protected work may result in a civil fine. See § 407. The Register of Copyrights may exempt certain categories of material from the deposit requirement.

In 1989 the U.S. joined the Berne Convention for the Protection of Literary and Artistic Works. In accordance with the requirements of the Berne Convention, notice is no longer a condition of protection for works published after March 1, 1989. This change to the notice requirement applies only prospectively to copies of works publicly distributed after March 1, 1989.

The Berne Convention also modified the rule making copyright registration a precondition to commencing a lawsuit for infringement. For works originating from a Berne Convention country, an infringement action may be initiated without registering the work with the U.S. Copyright Office. However, for works of U.S. origin, registration prior to filing suit is still required.

The federal agency charged with administering the act is the Copyright Office of the Library of Congress. See § 701 of the act. Its regulations are found in Parts 201 - 204 of title 37 of the Code of Federal Regulations."

To directly answer your question, yes, you can mock some methods without mocking others. This is called a partial mock. See the Mockito documentation on partial mocks for more information.

For your example, you can do something like the following, in your test:

Stock stock = mock(Stock.class);
when(stock.getPrice()).thenReturn(100.00);    // Mock implementation
when(stock.getQuantity()).thenReturn(200);    // Mock implementation
when(stock.getValue()).thenCallRealMethod();  // Real implementation

In that case, each method implementation is mocked, unless specify thenCallRealMethod() in the when(..) clause.

There is also a possibility the other way around with spy instead of mock:

Stock stock = spy(Stock.class);
when(stock.getPrice()).thenReturn(100.00);    // Mock implementation
when(stock.getQuantity()).thenReturn(200);    // Mock implementation
// All other method call will use the real implementations

In that case, all method implementation are the real one, except if you have defined a mocked behaviour with when(..).

There is one important pitfall when you use when(Object) with spy like in the previous example. The real method will be called (because stock.getPrice() is evaluated before when(..) at runtime). This can be a problem if your method contains logic that should not be called. You can write the previous example like this:

Stock stock = spy(Stock.class);
doReturn(100.00).when(stock).getPrice();    // Mock implementation
doReturn(200).when(stock).getQuantity();    // Mock implementation
// All other method call will use the real implementations

Another possibility may be to use org.mockito.Mockito.CALLS_REAL_METHODS, such as:

Stock MOCK_STOCK = Mockito.mock( Stock.class, CALLS_REAL_METHODS );

This delegates unstubbed calls to real implementations.

However, with your example, I believe it will still fail, since the implementation of getValue() relies on quantity and price, rather than getQuantity() and getPrice(), which is what you've mocked.

Another possibility is to avoid mocks altogether:

@Test
public void getValueTest() {
    Stock stock = new Stock(100.00, 200);
    double value = stock.getValue();
    assertEquals("Stock value not correct", 100.00*200, value, .00001);
}

realpath isn't available on all linux flavors, but readlink should be.

readlink -f symlinkName

The above should do the trick.

Alternatively, if you don't have either of the above installed, you can do the following if you have python 2.6 (or later) installed

python -c 'import os.path; print(os.path.realpath("symlinkName"))'

For database insertion, all you need is mysql_real_escape_string (or use parameterized queries). You generally don't want to alter data before saving it, which is what would happen if you used htmlentities. That would lead to a garbled mess later on when you ran it through htmlentities again to display it somewhere on a webpage.

Use htmlentities when you are displaying the data on a webpage somewhere.

Somewhat related, if you are sending submitted data somewhere in an email, like with a contact form for instance, be sure to strip newlines from any data that will be used in the header (like the From: name and email address, subect, etc)

$input = preg_replace('/\s+/', ' ', $input);

If you don't do this it's just a matter of time before the spam bots find your form and abuse it, I've learned the hard way.

#include <unistd.h>

int usleep(useconds_t useconds); //pass in microseconds

Sure, you just call it from within the SP, there's no special syntax.

Ex:

   PROCEDURE some_sp
   AS
   BEGIN
      some_other_sp('parm1', 10, 20.42);
   END;

If the procedure is in a different schema than the one the executing procedure is in, you need to prefix it with schema name.

   PROCEDURE some_sp
   AS
   BEGIN
      other_schema.some_other_sp('parm1', 10, 20.42);
   END;

As per Basil Bourque's comment, this is the updated answer for this question, taking into account the new API of Java 8:

    String myDateString = "13:24:40";
    LocalTime localTime = LocalTime.parse(myDateString, DateTimeFormatter.ofPattern("HH:mm:ss"));
    int hour = localTime.get(ChronoField.CLOCK_HOUR_OF_DAY);
    int minute = localTime.get(ChronoField.MINUTE_OF_HOUR);
    int second = localTime.get(ChronoField.SECOND_OF_MINUTE);

    //prints "hour: 13, minute: 24, second: 40":
    System.out.println(String.format("hour: %d, minute: %d, second: %d", hour, minute, second));

Remarks:

• since the OP's question contains a concrete example of a time instant containing only hours, minutes and seconds (no day, month, etc.), the answer above only uses LocalTime. If wanting to parse a string that also contains days, month, etc. then LocalDateTime would be required. Its usage is pretty much analogous to that of LocalTime.
• since the time instant int OP's question doesn't contain any information about timezone, the answer uses the LocalXXX version of the date/time classes (LocalTime, LocalDateTime). If the time string that needs to be parsed also contains timezone information, then ZonedDateTime needs to be used.

====== Below is the old (original) answer for this question, using pre-Java8 API: =====

I'm sorry if I'm gonna upset anyone with this, but I'm actually gonna answer the question. The Java API's are pretty huge, I think it's normal that someone might miss one now and then.

A SimpleDateFormat might do the trick here:

http://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html

It should be something like:

String myDateString = "13:24:40";
//SimpleDateFormat sdf = new SimpleDateFormat("hh:mm:ss");
//the above commented line was changed to the one below, as per Grodriguez's pertinent comment:
SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss");
Date date = sdf.parse(myDateString);

Calendar calendar = GregorianCalendar.getInstance(); // creates a new calendar instance
calendar.setTime(date);   // assigns calendar to given date 
int hour = calendar.get(Calendar.HOUR);
int minute; /... similar methods for minutes and seconds

The gotchas you should be aware of:

• the pattern you pass to SimpleDateFormat might be different then the one in my example depending on what values you have (are the hours in 12 hours format or in 24 hours format, etc). Look at the documentation in the link for details on this

• Once you create a Date object out of your String (via SimpleDateFormat), don't be tempted to use Date.getHour(), Date.getMinute() etc. They might appear to work at times, but overall they can give bad results, and as such are now deprecated. Use the calendar instead as in the example above.

For the ones who are getting the error while requesting JSON data:

If your are requesting JSON data, the JSON might be too large and that what cause the error to happen.

My solution is to copy the request link to new tab (get request from browser) copy the data to JSON viewer online where you have auto parsing and work on it there.

In my case only after I added gcm.jar to lib folder, it started to work. It was here: C:\adt-bundle-windows-x86_64-20131030\sdk\extras\google\gcm\gcm-client\dist

So the google-play-services.jar didn't work...

The source code for the Android mobile application open-gpstracker which you appreciated is available here.

You can checkout the code using SVN client application or via Git:

• svn checkout http://open-gpstracker.googlecode.com/svn/trunk/ open-gpstracker-read-only
• git clone https://code.google.com/p/open-gpstracker/

Debugging the source code will surely help you.

In a .git directory in the root of the project. Unlike some other version control systems, notably CVS, there are no additional directories in any of the subdirectories.

I would suggest you use Wireshark.

Steps:

1. Install Wireshark.
2. Select the network connection that you are using for the calls(for eg, select the Wifi if you are using it)
3. There will be many requests and responses, close extra applications.
4. Usually the requests are in green color, once you spot your request, copy the destination address and use the filter on top by typing ip.dst==52.187.182.185 by putting the destination address.

You can make use of other filtering techniques mentioned here to get specific traffic.

Your example is correct but not very portable. There is also a slightly cleaner syntax that can be used (as pointed out by @namespace-sid, among others).

However, suppose the templated class is part of some library that is to be shared...

Should other versions of the templated class be compiled?

Is the library maintainer supposed to anticipate all possible templated uses of the class?

An Alternate Approach

Add a third file that is the template implementation/instantiation file in your sources.

lib/foo.hpp in/from library

#pragma once

template <typename T>
class foo
{
public:
    void bar(const T&);
};

lib/foo.cpp compiling this file directly just wastes compilation time

// Include guard here, just in case
#pragma once

#include "foo.hpp"

template <typename T>
void foo::bar(const T& arg)
{
    // Do something with `arg`
}

foo.MyType.cpp using the library, explicit template instantiation of foo<MyType>

// Consider adding "anti-guard" to make sure it's not included in other translation units
#if __INCLUDE_LEVEL__ != 0
  #error "Don't include this file"
#endif

// Yes, we include the .cpp file
#include <lib/foo.cpp>
#include "MyType.hpp"

template class foo<MyType>;

Of course, you can have multiple implementations in the third file. Or you might want multiple implementation files, one for each type (or set of types) you'd like to use, for instance.

This setup should reduce compile times, especially for heavily used complicated templated code, because you're not recompiling the same header file in each translation unit. It also enables better detection of which code needs to be recompiled, by compilers and build scripts, reducing incremental build burden.

Usage Examples

foo.declarations.hpp needs to know about foo<MyType>'s public interface but not .cpp sources

#pragma once

#include <lib/foo.hpp>
#include "MyType.hpp"

// Declare `temp`. Doesn't need to include `foo.cpp`
extern foo<MyType> temp;

examples.cpp can reference local declaration but also doesn't recompile foo<MyType>

#include "foo.declarations.hpp"

MyType instance;

// Define `temp`. Doesn't need to include `foo.cpp`
foo<MyType> temp;

void example_1() {
    // Use `temp`
    temp.bar(instance);
}

void example_2() {
    // Function local instance
    foo<MyType> temp2;

    // Use templated library function
    temp2.bar(instance);
}

error.cpp example that would work with pure header templates but doesn't here

#include <lib/foo.hpp>

// Causes compilation errors at link time since we never had the explicit instantiation:
// template class foo<int>;
// GCC linker gives an error: "undefined reference to `foo<int>::bar()'"

void linkerError()
{
    foo<int> nonExplicitlyInstantiatedTemplate;
}

Note that most compilers/linters/code helpers won't detect this as an error, since there is no error according to C++ standard. But when you go to link this translation unit into a complete executable, the linker won't find a defined version of foo<int>.

Converting SecretKeySpec to String and vice-versa: you can use getEncoded() method in SecretKeySpec which will give byteArray, from that you can use encodeToString() to get string value of SecretKeySpec in Base64 object.

While converting SecretKeySpec to String: use decode() in Base64 will give byteArray, from that you can create instance for SecretKeySpec with the params as the byteArray to reproduce your SecretKeySpec.

String mAesKey_string;
SecretKeySpec mAesKey= new SecretKeySpec(secretKey.getEncoded(), "AES");

//SecretKeySpec to String 
    byte[] byteaes=mAesKey.getEncoded();
    mAesKey_string=Base64.encodeToString(byteaes,Base64.NO_WRAP);

//String to SecretKeySpec
    byte[] aesByte = Base64.decode(mAesKey_string, Base64.NO_WRAP);
    mAesKey= new SecretKeySpec(aesByte, "AES");

If you have regular arrays and nothing fancy, this will do. Remember, using array_splice() for inserting elements really means insert before the start index. Be careful when moving elements, because moving up means $targetIndex -1, where as moving down means $targetIndex + 1.

class someArrayClass
{
    private const KEEP_EXISTING_ELEMENTS = 0;

    public function insertAfter(array $array, int $startIndex, $newElements)
    {
        return $this->insertBefore($array, $startIndex + 1, $newElements);
    }

    public function insertBefore(array $array, int $startIndex, $newElements)
    {
        return array_splice($array, $startIndex, self::KEEP_EXISTING_ELEMENTS, $newElements);
    }
}

It's valid, but rather nasty. I would suggest it's generally bad to allow fall-throughs as it can lead to some very messy spaghetti code.

It's almost certainly better to break these cases up into several switch statements or smaller functions.

[edit] @Tristopia: Your example:

Example from UCS-2 to UTF-8 conversion 

r is the destination array, 
wc is the input wchar_t  

switch(utf8_length) 
{ 
    /* Note: code falls through cases! */ 
    case 3: r[2] = 0x80 | (wc & 0x3f); wc >>= 6; wc |= 0x800; 
    case 2: r[1] = 0x80 | (wc & 0x3f); wc >>= 6; wc |= 0x0c0; 
    case 1: r[0] = wc;
}

would be clearer as to it's intention (I think) if it were written like this:

if( utf8_length >= 1 )
{
    r[0] = wc;

    if( utf8_length >= 2 )
    {
        r[1] = 0x80 | (wc & 0x3f); wc >>= 6; wc |= 0x0c0; 

        if( utf8_length == 3 )
        {
            r[2] = 0x80 | (wc & 0x3f); wc >>= 6; wc |= 0x800; 
        }
    }
}   

[edit2] @Tristopia: Your second example is probably the cleanest example of a good use for follow-through:

for(i=0; s[i]; i++)
{
    switch(s[i])
    {
    case '"': 
    case '\'': 
    case '\\': 
        d[dlen++] = '\\'; 
        /* fall through */ 
    default: 
        d[dlen++] = s[i]; 
    }

..but personally I would split the comment recognition into it's own function:

bool isComment(char charInQuestion)
{   
    bool charIsComment = false;
    switch(charInQuestion)
    {
    case '"': 
    case '\'': 
    case '\\': 
        charIsComment = true; 
    default: 
        charIsComment = false; 
    } 
    return charIsComment;
}

for(i=0; s[i]; i++)
{
    if( isComment(s[i]) )
    {
        d[dlen++] = '\\'; 
    }
    d[dlen++] = s[i]; 
}

selenium.keyPress("css=input.tagit-input.ui-autocomplete-input", "13");

"yyyy-mm-dd hh:mm:ss.000" format does not work in all locales. For some (at least Danish) "yyyy-mm-dd hh:mm:ss,000" will work better.

as replied by user662894.

I want to add: Don't try to get the microseconds from, say, SQL Server's datetime2 datatype: Excel can't handle more than 3 fractional seconds (i.e. milliseconds).

So "yyyy-mm-dd hh:mm:ss.000000" won't work, and when Excel is fed this kind of string (from the CSV file), it will perform rounding rather than truncation.

This may be fine except when microsecond precision matters, in which case you are better off by NOT triggering an automatic datatype recognition but just keep the string as string...

Obviously it's a problem with your internet connection. Check, if you can reach http://repo.spring.io with your browser. If yes, check if you need to configure a proxy server. If no, you should contact your internet provider.

Here is the documentation, how you configure a proxy server for Maven: https://maven.apache.org/guides/mini/guide-proxies.html

Try this code:

$(document).ready(function(){
    $('#YourControlID').click(function(){
        if() { //your condition
            $.messager.show({  
                title:'My Title',  
                msg:'The message content',  
                showType:'fade',  
                style:{  
                    right:'',  
                    bottom:''  
                }  
            });  
        }
    });
});

Example case, when I get file from remote server and save it in local machine
package connector;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;

import com.jcraft.jsch.ChannelSftp;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.JSchException;
import com.jcraft.jsch.Session;
import com.jcraft.jsch.SftpException;

public class Main {

    public static void main(String[] args) throws JSchException, SftpException, IOException {
        // TODO Auto-generated method stub
        String username = "XXXXXX";
        String host = "XXXXXX";
        String passwd = "XXXXXX";
        JSch conn = new JSch();
        Session session = null;
        session = conn.getSession(username, host, 22);
        session.setPassword(passwd);
        session.setConfig("StrictHostKeyChecking", "no");
        session.connect();

        ChannelSftp channel = null;
        channel = (ChannelSftp)session.openChannel("sftp");
        channel.connect();

        channel.cd("/tmp/qtmp");

        InputStream in = channel.get("testScp");
        String lf = "OBJECT_FILE";
        FileOutputStream tergetFile = new FileOutputStream(lf);

        int c;
        while ( (c= in.read()) != -1 ) {
            tergetFile.write(c);
        } 

        in.close();
        tergetFile.close();

        channel.disconnect();
        session.disconnect();   

    }

}

The following creates a generic function, taking an array of any size and of any type by reference:

template<typename T, std::size_t S>
void my_func(T (&arr)[S]) {
   // do stuff
}

play with the code.

Use the below function (changing [E:E] to the appropriate range for your needs) to circumvent this issue (or change to any other format such as "mm/dd/yyyy"):

[E:E].Select
With Selection
    .NumberFormat = "General"
    .Value = .Value
End With

P.S. In my experience, this VBA solution works SIGNIFICANTLY faster on large data sets and is less likely to crash Excel than using the 'warning box' method.

Since C++17 you can use range-based for loops together with structured bindings for iterating over your map. This improves readability, as you reduce the amount of needed first and second members in your code:

std::map<std::string, std::pair<std::string, std::string>> myMap;
myMap["x"] = { "a", "b" };
myMap["y"] = { "c", "d" };

for (const auto &[k, v] : myMap)
    std::cout << "m[" << k << "] = (" << v.first << ", " << v.second << ") " << std::endl;

Output:

m[x] = (a, b)
m[y] = (c, d)

Code on Coliru

As an empty string is not valid JSON it would be incorrect for JSON.parse('') to return null because "null" is valid JSON. e.g.

JSON.parse("null");

returns null. It would be a mistake for invalid JSON to also be parsed to null.

While an empty string is not valid JSON two quotes is valid JSON. This is an important distinction.

Which is to say a string that contains two quotes is not the same thing as an empty string.

JSON.parse('""');

will parse correctly, (returning an empty string). But

JSON.parse('');

will not.

Valid minimal JSON strings are

The empty object '{}'

The empty array '[]'

The string that is empty '""'

A number e.g. '123.4'

The boolean value true 'true'

The boolean value false 'false'

The null value 'null'

If you have a chance, I would recommand getting a copy of Lisp/Scheme, and doing some projects in it. Most of the ideas that have lately become bandwagons were expressed in Lisp decades ago: functional programming, continuations (as closures), garbage collection, even XML.

So that would be a good way to get a head start on all these current ideas, and a few more besides, like symbolic computation.

You should know what functional programming is good for, and what it isn't good for. It isn't good for everything. Some problems are best expressed in terms of side-effects, where the same question gives differet answers depending on when it is asked.

You have to use Javascript Filereader for this. (Introduction into filereader-api: http://www.html5rocks.com/en/tutorials/file/dndfiles/)

Once the user have choose a image you can read the file-path of the chosen image and place it into your html.

Example:

<form id="form1" runat="server">
    <input type='file' id="imgInp" />
    <img id="blah" src="#" alt="your image" />
</form>

Javascript:

function readURL(input) {
    if (input.files && input.files[0]) {
        var reader = new FileReader();

        reader.onload = function (e) {
            $('#blah').attr('src', e.target.result);
        }

        reader.readAsDataURL(input.files[0]);
    }
}

$("#imgInp").change(function(){
    readURL(this);
});

The Change event gets called even if you click on cancel..

It sounds like your workbook got set to Manual Calculation. You can change this to Automatic by going to Formulas > Calculation > Calculation Options > Automatic.

Manual calculation can be useful to reduce computational load and improve responsiveness in workbooks with large amounts of formulas. The idea is that you can look at data and make changes, then choose when you want to make your computer go through the effort of calculation.

The dplyr package contains summarise_all for this aim:

library(dplyr)
# summarise_all was replaced with the summarise(acrosss(..)) syntax dplyr >=1.00
df %>% group_by(grp) %>% summarise(across(everything(), list(mean)))
#> # A tibble: 3 x 5
#>     grp     a     b     c     d
#>   <int> <dbl> <dbl> <dbl> <dbl>
#> 1     1  3.08  2.98  2.98  2.91
#> 2     2  3.03  3.04  2.97  2.87
#> 3     3  2.85  2.95  2.95  3.06

Alternatively, the purrrlyr package provides the same functionality:

library(purrrlyr)
df %>% slice_rows("grp") %>% dmap(mean)
#> # A tibble: 3 x 5
#>     grp     a     b     c     d
#>   <int> <dbl> <dbl> <dbl> <dbl>
#> 1     1  3.08  2.98  2.98  2.91
#> 2     2  3.03  3.04  2.97  2.87
#> 3     3  2.85  2.95  2.95  3.06

Also don't forget about data.table (use keyby to sort sort groups):

library(data.table)
setDT(df)[, lapply(.SD, mean), keyby = grp]
#>    grp        a        b        c        d
#> 1:   1 3.079412 2.979412 2.979412 2.914706
#> 2:   2 3.029126 3.038835 2.967638 2.873786
#> 3:   3 2.854701 2.948718 2.951567 3.062678

Let's try to compare performance.

library(dplyr)
library(purrrlyr)
library(data.table)
library(bench)
set.seed(123)
n <- 10000
df <- data.frame(

  grp = sample(1:3, n, replace = TRUE)
)
dt <- setDT(df)
mark(
  dplyr = df %>% group_by(grp) %>% summarise(across(everything(), list(mean))),
  purrrlyr = df %>% slice_rows("grp") %>% dmap(mean),
  data.table = dt[, lapply(.SD, mean), keyby = grp],
  check = FALSE
)

I have found another way of forcing re-run CI builds and other triggers:

1. Run git commit --amend --no-edit without any changes. This will recreate the last commit in the current branch.
2. git push --force-with-lease origin pr-branch.

You can use Tuple for constant variable :

• A tuple is a collection which is ordered and unchangeable

my_tuple = (1, "Hello", 3.4)
print(my_tuple[0])

According to the docs numpy.loadtxt is

a fast reader for simply formatted files. The genfromtxt function provides more sophisticated handling of, e.g., lines with missing values.

so there are only a few options to handle more complicated files. As mentioned numpy.genfromtxt has more options. So as an example you could use

import numpy as np
data = np.genfromtxt('e:\dir1\datafile.csv', delimiter=',', skip_header=10,
                     skip_footer=10, names=['x', 'y', 'z'])

to read the data and assign names to the columns (or read a header line from the file with names=True) and than plot it with

ax1.plot(data['x'], data['y'], color='r', label='the data')

I think numpy is quite well documented now. You can easily inspect the docstrings from within ipython or by using an IDE like spider if you prefer to read them rendered as HTML.

Alternatively there is the built-in function pd.get_dummies for these kinds of assignments:

w['female'] = pd.get_dummies(w['female'],drop_first = True)

This gives you a data frame with two columns, one for each value that occurs in w['female'], of which you drop the first (because you can infer it from the one that is left). The new column is automatically named as the string that you replaced.

This is especially useful if you have categorical variables with more than two possible values. This function creates as many dummy variables needed to distinguish between all cases. Be careful then that you don't assign the entire data frame to a single column, but instead, if w['female'] could be 'male', 'female' or 'neutral', do something like this:

w = pd.concat([w, pd.get_dummies(w['female'], drop_first = True)], axis = 1])
w.drop('female', axis = 1, inplace = True)

Then you are left with two new columns giving you the dummy coding of 'female' and you got rid of the column with the strings.

Where do these values come from? The documentation for android:fontFamily does not list this information in any place

These are indeed not listed in the documentation. But they are mentioned here under the section 'Font families'. The document lists every new public API for Android Jelly Bean 4.1.

In the styles.xml file in the application I'm working on somebody listed this as the font family, and I'm pretty sure it's wrong:

Yes, that's wrong. You don't reference the font file, you have to use the font name mentioned in the linked document above. In this case it should have been this:

<item name="android:fontFamily">sans-serif</item>

Like the linked answer already stated, 12 variants are possible:

Added in Android Jelly Bean (4.1) - API 16 :

Regular (default):

<item name="android:fontFamily">sans-serif</item>
<item name="android:textStyle">normal</item>

<item name="android:textStyle">bold</item>

Bold-italic:

<item name="android:fontFamily">sans-serif</item>
<item name="android:textStyle">bold|italic</item>

Light:

<item name="android:textStyle">normal</item>

Condensed italic:

<item name="android:fontFamily">sans-serif-condensed</item>
<item name="android:textStyle">italic</item>

Condensed bold:

<item name="android:fontFamily">sans-serif-condensed</item>
<item name="android:textStyle">bold</item>

Condensed bold-italic:

<item name="android:fontFamily">sans-serif-condensed</item>
<item name="android:textStyle">bold|italic</item>

Added in Android Lollipop (v5.0) - API 21 :

Medium:

<item name="android:fontFamily">sans-serif-medium</item>
<item name="android:textStyle">normal</item>

Medium-italic:

<item name="android:fontFamily">sans-serif-medium</item>
<item name="android:textStyle">italic</item>

Black:

<item name="android:fontFamily">sans-serif-black</item>
<item name="android:textStyle">italic</item>

For quick reference, this is how they all look like:

You can get the original host from X-Forwarded-For header field.

On SmtpClient there is an EnableSsl property that you would set.

i.e.

SmtpClient client = new SmtpClient(exchangeServer);
client.EnableSsl = true;
client.Send(msg);

what about using materialDesign HintAssist ? i'm using this which also you can add floating hint too :

<TextBox Width="150" Height="40" Text="hello" materialDesign:HintAssist.Hint="address"  materialDesign:HintAssist.IsFloating="True"></TextBox>

i installed Material Design with Nuget Package there is installation guide in documentation link

You can't. This is an open issue in TypeScript: https://github.com/Microsoft/TypeScript/issues/19573

I discovered that I had to include

body { width:100%; }

for "margin: 0 auto" to work for tables.

This is how I do this with JQuery...

using the jquery-watermark plugin (http://code.google.com/p/jquery-watermark/)

$('#inputId').watermark('Please select a name');

works like a charm!!

There is some good documentation at that google code site.

Hope this helps!

Don't use == in PHP. It will not do what you expect. Even if you are comparing strings to strings, PHP will implicitly cast them to floats and do a numerical comparison if they appear numerical.

For example '1e3' == '1000' returns true. You should use === instead.

No, you do not need to check whether you’re already on the main thread. By dispatching the block to the main queue, you’re just scheduling the block to be executed serially on the main thread, which happens when the corresponding run loop is run.

If you already are on the main thread, the behaviour is the same: the block is scheduled, and executed when the run loop of the main thread is run.

jQuery 3

As of jQuery 3, removeAttr does not set the corresponding property to false anymore:

Prior to jQuery 3.0, using .removeAttr() on a boolean attribute such as checked, selected, or readonly would also set the corresponding named property to false. This behavior was required for ancient versions of Internet Explorer but is not correct for modern browsers because the attribute represents the initial value and the property represents the current (dynamic) value.

It is almost always a mistake to use .removeAttr( "checked" ) on a DOM element. The only time it might be useful is if the DOM is later going to be serialized back to an HTML string. In all other cases, .prop( "checked", false ) should be used instead.

Changelog

Hence only .prop('checked',false) is correct way when using this version.

Original answer (from 2011):

For attributes which have underlying boolean properties (of which checked is one), removeAttr automatically sets the underlying property to false. (Note that this is among the backwards-compatibility "fixes" added in jQuery 1.6.1).

So, either will work... but the second example you gave (using prop) is the more correct of the two. If your goal is to uncheck the checkbox, you really do want to affect the property, not the attribute, and there's no need to go through removeAttr to do that.

You can try this:

CommandArgument='<%# "scrapid=" + Eval("ScrapId")+"&"+"UserId="+ Eval("UserId")%>'

Create a file named tsconfig.json in your project root and include following lines in it:

Please note that outDir should be the path of the directory to receive compiled JS files, and rootDir should be the path of the directory containing your source (.ts) files.

Open a terminal and run tsc -w, it'll compile any .ts file in src directory into .js and store them in ts-built directory.

The overall dimensions of a range are in its Width and Height properties.

I elaborated on dream83619 answer to make it handle nested Hibernate @Fetch annotations. I used recursive method to find annotations in nested associated classes.

So you have to implement custom repository and override getQuery(spec, domainClass, sort) method. Unfortunately you also have to copy all referenced private methods :(.

Here is the code, copied private methods are omitted.
EDIT: Added remaining private methods.

@NoRepositoryBean
public class EntityGraphRepositoryImpl<T, ID extends Serializable> extends SimpleJpaRepository<T, ID> {

    private final EntityManager em;
    protected JpaEntityInformation<T, ?> entityInformation;

    public EntityGraphRepositoryImpl(JpaEntityInformation<T, ?> entityInformation, EntityManager entityManager) {
        super(entityInformation, entityManager);
        this.em = entityManager;
        this.entityInformation = entityInformation;
    }

    @Override
    protected <S extends T> TypedQuery<S> getQuery(Specification<S> spec, Class<S> domainClass, Sort sort) {
        CriteriaBuilder builder = em.getCriteriaBuilder();
        CriteriaQuery<S> query = builder.createQuery(domainClass);

        Root<S> root = applySpecificationToCriteria(spec, domainClass, query);

        query.select(root);
        applyFetchMode(root);

        if (sort != null) {
            query.orderBy(toOrders(sort, root, builder));
        }

        return applyRepositoryMethodMetadata(em.createQuery(query));
    }

    private Map<String, Join<?, ?>> joinCache;

    private void applyFetchMode(Root<? extends T> root) {
        joinCache = new HashMap<>();
        applyFetchMode(root, getDomainClass(), "");
    }

    private void applyFetchMode(FetchParent<?, ?> root, Class<?> clazz, String path) {
        for (Field field : clazz.getDeclaredFields()) {
            Fetch fetch = field.getAnnotation(Fetch.class);

            if (fetch != null && fetch.value() == FetchMode.JOIN) {
                FetchParent<?, ?> descent = root.fetch(field.getName(), JoinType.LEFT);
                String fieldPath = path + "." + field.getName();
                joinCache.put(path, (Join) descent);

                applyFetchMode(descent, field.getType(), fieldPath);
            }
        }
    }

        Root<U> root = query.from(domainClass);

        if (spec == null) {
            return root;
        }

        CriteriaBuilder builder = em.getCriteriaBuilder();

Agree with neubert about the DECLARE statements, this will fix syntax error. But I would suggest you to avoid using openning cursors, they may be slow.

For your task: use INSERT...SELECT statement which will help you to copy data from one table to another using only one query.

INSERT ... SELECT Syntax.

If you are generating new *.json or modifying existing josn file the use "indent" parameter for pretty view json format.

import json
responseData = json.loads(output)
with open('twitterData.json','w') as twitterDataFile:    
    json.dump(responseData, twitterDataFile, indent=4)

Just another way to do it is to use the built-in file access technique:

(get-item .\filename.exe).VersionInfo | FL

You can also get any particular property off the VersionInfo, thus:

(get-item .\filename.exe).VersionInfo.FileVersion

This is quite close to the dir technique.

WE had this issue. everything was setup fine in terms of permissions and security.

after MUCH needling around in the haystack. the issue was some sort of heuristics. in the email body , anytime a certain email address was listed, we would get the above error message from our exchange server.

it took 2 days of crazy testing and hair pulling to find this.

so if you have checked everything out, try changing the email body to only the word 'test'. If after that, your email goes out fine, you are having some sort of spam/heuristic filter issue like we were

basically same for VS2012e: TOOLS > Options > Environment > Fonts and Colors > Display Items: Plain Text > "Item background" dropdown selector

You could use On Error Resume Next then there is no need to loop through all the sheets in the workbook.

With On Error Resume Next the errors are not propagated, but are suppressed instead. So here when the sheets does't exist or when for any reason can't be deleted, nothing happens. It is like when you would say : delete this sheets, and if it fails I don't care. Excel is supposed to find the sheet, you will not do any searching.

Note: When the workbook would contain only those two sheets, then only the first sheet will be deleted.

Dim book
Dim sht as Worksheet

set book= Workbooks("SomeBook.xlsx")

On Error Resume Next

Application.DisplayAlerts=False 

Set sht = book.Worksheets("ID Sheet")
sht.Delete

Set sht = book.Worksheets("Summary")
sht.Delete

Application.DisplayAlerts=True 

On Error GoTo 0

tested on IE11, FF53, GC58 :

onclick="var e=this;setTimeout(function(){e.disabled=true;},0);return true;"

Please follow below steps :

1.Open Your project.

2.Go to the Left side of the Gradle button.

3.Look at below image.

4.Click button above image show.

5.if this type of view you are not in offline mode.

6.Go to Build and rebuild the project.

All above point is work for me.

Just like the accepted answer says a HashSet doesn't have an order. If order is important you can continue to use a List and check if it contains the item before you add it.

if (_remoteDevices.Contains(rDevice))
    _remoteDevices.Add(rDevice);

Performing List.Contains() on a custom class/object requires implementing IEquatable<T> on the custom class or overriding the Equals. It's a good idea to also implement GetHashCode in the class as well. This is per the documentation at https://msdn.microsoft.com/en-us/library/ms224763.aspx

public class RemoteDevice: IEquatable<RemoteDevice>
{
    private readonly int id;
    public RemoteDevice(int uuid)
    {
        id = id
    }
    public int GetId
    {
        get { return id; }
    }

    // ...

    public bool Equals(RemoteDevice other)
    {
        if (this.GetId == other.GetId)
            return true;
        else
            return false;
    }
    public override int GetHashCode()
    {
        return id;
    }
}

It shouldn't matter if the word has an even or odd amount fo letters:

def is_palindrome(word):
    if word == word[::-1]:
        return True
    else:
        return False

For those that are still experiencing problems, like I have(I am using Ubuntu 16.04), I had to put in the following commands in order to get some gems like bcrypt, pg, and others installed. They are all similar to the ones above except for one.

sudo apt-get install ruby-dev -y
sudo apt-get install libpq-dev -y
sudo apt-get install libmysqlclient-dev
sudo apt-get install build-essential patch -y

This allowed me to install gems like, PG, bcrypt, and recaptcha.

$fname = "database.php";
$fhandle = fopen($fname,"r");
$content = fread($fhandle,filesize($fname));
$content = str_replace("192.168.1.198", "localhost", $content);

$fhandle = fopen($fname,"w");
fwrite($fhandle,$content);
fclose($fhandle);

Consider using NumberFormatter for this purpose, it provides more flexibility if you want to print the percentage sign of the ratio or if you have things like currency and large numbers.

let amount = 10.000001
let formatter = NumberFormatter()
formatter.numberStyle = .decimal
formatter.maximumFractionDigits = 2
let formattedAmount = formatter.string(from: amount as NSNumber)! 
print(formattedAmount) // 10

I got this error after injecting a Service which used HTTPClient into a class. The class was again used in the service, so it created a circular dependency. I could compile the app with warnings, but in browser console the error occurred

"No provider for HttpClient! (MyService -> HttpClient)"

and it broke the app.

This works:

import { HttpClient, HttpClientModule, HttpHeaders } from '@angular/common/http';
import { MyClass } from "../classes/my.class";

@Injectable()
export class MyService {
  constructor(
    private http: HttpClient
  ){
    // do something with myClass Instances
  }      
}
.
.
.
export class MenuItem {
  constructor(

  ){}
}

This breaks the app

import { HttpClient, HttpClientModule, HttpHeaders } from '@angular/common/http';
import { MyClass } from "../classes/my.class";

@Injectable()
export class MyService {
  constructor(
    private http: HttpClient
  ){
    // do something with myClass Instances
  }      
}
.
.
.
import { MyService } from '../services/my.service';
export class MyClass {
  constructor(
    let injector = ReflectiveInjector.resolveAndCreate([MyService]);
    this.myService = injector.get(MyService);
  ){}
}

After injecting MyService in MyClass I got the circular dependency warning. CLI compiled anyway with this warning but the app did not work anymore and the error was given in browser console. So in my case it didn't had to do anything with @NgModule but with circular dependencies. I recommend to solve the case sensitive naming warnings if your problem still exist.

My issue was caused because I have an & character in my Windows user name, so when installed in the default path I was getting the following error after running bin/studio.bat

object.__del__(self) is called when the instance is about to be destroyed.

>>> class Test:
...     def __del__(self):
...         print "deleted"
... 
>>> test = Test()
>>> del test
deleted

Object is not deleted unless all of its references are removed(As quoted by ethan)

Also, From Python official doc reference:

del x doesn’t directly call x.del() — the former decrements the reference count for x by one, and the latter is only called when x‘s reference count reaches zero

Both the size attribute in HTML and the width property in CSS will set the width of an <input>. If you want to set the width to something closer to the width of each character use the **ch** unit as in:

input {
    width: 10ch;
}

AFAIK JSON.Net does not provide functionality for reading from a URL. So you need to do this in two steps:

using (var webClient = new System.Net.WebClient()) {
    var json = webClient.DownloadString(URL);
    // Now parse with JSON.Net
}

The PostgreSQL documentation on Character Types is a good reference for this. They are two different names for the same type.

This is a prototype to generate or destroy a controller or model in Rails:

rails generate/destroy controller/model [controller/model Name]

For example, if you need to generate a User Controller:

rails generate controller User

or

rails g controller User

If you want to destroy the User controller or revert to above action then use:

rails destroy controller User

or:

rails d controller User

I did some benchmarking for speed on these answers and was surprised to see percent in the scales package so touted, given its sluggishness. I imagine the advantage is its automatic detector for for proper formatting, but if you know what your data looks like it seems clear to be avoided.

Here are the results from trying to format a list of 100,000 percentages in (0,1) to a percentage in 2 digits:

library(microbenchmark)
x = runif(1e5)
microbenchmark(times = 100L, andrie1(), andrie2(), richie(), krlmlr())
# Unit: milliseconds
#   expr       min        lq      mean    median        uq       max
# 1 andrie1()  91.08811  95.51952  99.54368  97.39548 102.75665 126.54918 #paste(round())
# 2 andrie2()  43.75678  45.56284  49.20919  47.42042  51.23483  69.10444 #sprintf()
# 3  richie()  79.35606  82.30379  87.29905  84.47743  90.38425 112.22889 #paste(formatC())
# 4  krlmlr() 243.19699 267.74435 304.16202 280.28878 311.41978 534.55904 #scales::percent()

So sprintf emerges as a clear winner when we want to add a percent sign. On the other hand, if we only want to multiply the number and round (go from proportion to percent without "%", then round() is fastest:

# Unit: milliseconds
#        expr      min        lq      mean    median        uq       max
# 1 andrie1()  4.43576  4.514349  4.583014  4.547911  4.640199  4.939159 # round()
# 2 andrie2() 42.26545 42.462963 43.229595 42.960719 43.642912 47.344517 # sprintf()
# 3  richie() 64.99420 65.872592 67.480730 66.731730 67.950658 96.722691 # formatC()

Check the daemon option in nginx.conf file. It has to be ON. Or you can simply rip out this line from config file. This option is fully described here http://nginx.org/en/docs/ngx_core_module.html#daemon

I use a similar approach like @Ofaim

private bool jobSaved = true;
private bool JobSaved    
{ 
    get => jobSaved; 
    set
    {
        if (value == jobSaved) return;
        jobSaved = value;

        OnPropertyChanged();
        OnPropertyChanged("EnableSaveButton");
    }
}

public bool EnableSaveButton => !jobSaved;

I was able to accomplish editing the default.aspx page by:

• Opening the site in SharePoint Designer 2013
• Then clicking 'All Files' to view all of the files,
• Then right-click -> Edit file in Advanced Mode.

By doing that I was able to remove the tagprefix causing a problem on my page.

I've created a jQuery plugin that provides 4 additonal placements: topLeft, topRight, bottomLeft, bottomRight

You just include either the minified js or unminified js and have the matching css (minified vs unminified) in the same folder.

Was just working with Nativescript's fetchModule and figured out my own solution using string manipulation. Append the query string bit by bit to the url. Here is an example where query is passed as a json object (query = {order_id: 1}):

function performGetHttpRequest(fetchLink='http://myapi.com/orders', query=null) {
    if(query) {
        fetchLink += '?';
        let count = 0;
        const queryLength = Object.keys(query).length;
        for(let key in query) {
            fetchLink += key+'='+query[key];
            fetchLink += (count < queryLength) ? '&' : '';
            count++;
        }
    }
    // link becomes: 'http://myapi.com/orders?order_id=1'
    // Then, use fetch as in MDN and simply pass this fetchLink as the url.
}

I tested this over a multiple number of query parameters and it worked like a charm :) Hope this helps someone.
