As a newbie, I faced the same 'problem'.

In newbie terms : when you call plot(), the graph window gets the focus and you cannot enter further commands into R. That is when you conclude that you must close the graph window to return to R. However, some commands, like identify(), act on open/active graph windows. When identify() cannot find an open/active graph window, it gives this error message.

However, you can simply click on the R window without closing the graph window. Then you can type more commands at the R prompt, like identify() etc.

A quick google found this post that describes how to do what you want for both single and multiple select lists in IE. The solution seems pretty elegant as well:

$('#clickme').click(function() {
        $('#selectmenu option').attr('selected', false);

}); 

Technically, the char* is not an array, but a pointer to a char.

Similarly, char** is a pointer to a char*. Making it a pointer to a pointer to a char.

C and C++ both define arrays behind-the-scenes as pointer types, so yes, this structure, in all likelihood, is array of arrays of chars, or an array of strings.

Try this

First Page

<?php
   session_start();
   $_SESSION['myvar']='myvalue';
?>

Second page

 <?php
   session_start();
   echo $_SESSION['myvar'];
 ?>

I read the following and think it makes sense too:

Taking Care of Business

Remember, one of the most important OO rules is that an object is responsible for itself. This means that issues regarding the life cycle of a class should be handled in the class, not delegated to language constructs like static, and so on.

from the book Objected-Oriented Thought Process 4th Ed.

I know this is an old post but i want to share my experience.

HTML:

<input type="text" placeholder="Username or E-Mail" required data-required-message="E-Mail or Username is Required!">

Javascript (jQuery):

$('input[required]').on('invalid', function() {
    this.setCustomValidity($(this).data("required-message"));
});

This is a very simple sample. I hope this can help to anyone.

One example, if you need to reference/join the same data set multiple times you can do so by defining a CTE. Therefore, it can be a form of code re-use.

An example of self referencing is recursion: Recursive Queries Using CTE

For exciting Microsoft definitions Taken from Books Online:

A CTE can be used to:

• Create a recursive query. For more information, see Recursive Queries Using Common Table Expressions.

• Substitute for a view when the general use of a view is not required; that is, you do not have to store the definition in metadata.

• Enable grouping by a column that is derived from a scalar subselect, or a function that is either not deterministic or has external access.

• Reference the resulting table multiple times in the same statement.

you can use

find .

to search all files/dirs in the current directory recurive

Than you can pipe the output the xargs command like so

find . | xargs 'command here'

if you are sub-classing the UITableView you need to do this...

-(void)didMoveToSuperview {
    [super didMoveToSuperview];
    self.tableFooterView = [UIView new];
}

OK, so I found the answer from http://binglongx.wordpress.com/2009/01/26/visual-c-does-not-generate-lib-file-for-a-dll-project/ says that this problem was caused by not exporting any symbols and further instructs on how to export symbols to create the lib file. To do so, add the following code to your .h file for your DLL.

#ifdef BARNABY_EXPORTS
#define BARNABY_API __declspec(dllexport)
#else
#define BARNABY_API __declspec(dllimport)
#endif

Where BARNABY_EXPORTS and BARNABY_API are unique definitions for your project. Then, each function you export you simply precede by:

BARNABY_API int add(){
}

This problem could have been prevented either by clicking the Export Symbols box on the new project DLL Wizard or by voting yes for lobotomies for computer programmers.

Unfortunately, ggplot2 does not offer a way to do this (easily) without transforming your data into long format. You can try to fight it but it will just be easier to do the data transformation. Here all the methods, including melt from reshape2, gather from tidyr, and pivot_longer from tidyr: Reshaping data.frame from wide to long format

Here's a simple example using pivot_longer:

> df <- data.frame(time = 1:5, a = 1:5, b = 3:7)
> df
  time a b
1    1 1 3
2    2 2 4
3    3 3 5
4    4 4 6
5    5 5 7

> df_wide <- df %>% pivot_longer(c(a, b), names_to = "colname", values_to = "val")
> df_wide
# A tibble: 10 x 3
    time colname   val
   <int> <chr>   <int>
 1     1 a           1
 2     1 b           3
 3     2 a           2
 4     2 b           4
 5     3 a           3
 6     3 b           5
 7     4 a           4
 8     4 b           6
 9     5 a           5
10     5 b           7

As you can see, pivot_longer puts the selected column names in whatever is specified by names_to (default "name"), and puts the long values into whatever is specified by values_to (default "value"). If I'm ok with the default names, I can use use df %>% pivot_longer(c("a", "b")).

Now you can plot as normal, ex.

ggplot(df_wide, aes(x = time, y = val, color = colname)) + geom_line()

Taking the script from onedaywhen, I modified it to also show which table each entry comes from.

DECLARE @table1 NVARCHAR(80)= 'table 1 name'
DECLARE @table2 NVARCHAR(80)= 'table 2 name'
DECLARE @sql NVARCHAR (1000)

SET @sql = 
'
SELECT ''' + @table1 + ''' AS table_name,* FROM
(
SELECT * FROM ' + @table1 + '
EXCEPT
SELECT * FROM ' + @table2 + '
) x

UNION 

SELECT ''' + @table2 + ''' AS table_name,* FROM 
(
SELECT * FROM ' + @table2 + '
EXCEPT
SELECT * FROM ' + @table1 + '
) y
'

EXEC sp_executesql @stmt = @sql

Try using this:

$(".move_to").on("click", function(e){
    e.preventDefault();
    $('#contactsForm').attr('action', "/test1").submit();
});

Moving the order in which you use .preventDefault() might fix your issue. You also didn't use function(e) so e.preventDefault(); wasn't working.

Here it is working: http://jsfiddle.net/TfTwe/1/ - first of all, click the 'Check action attribute.' link. You'll get an alert saying undefined. Then click 'Set action attribute.' and click 'Check action attribute.' again. You'll see that the form's action attribute has been correctly set to /test1.

First of all, android.graphics.Color is a class thats composed of only static methods. How and why did you create a new android.graphics.Color object? (This is completely useless and the object itself stores no data)

But anyways... I'm going to assume your using some object that actually stores data...

A integer is composed of 4 bytes (in java). Looking at the function getRGB() from the standard java Color object we can see java maps each color to one byte of the integer in the order ARGB (Alpha-Red-Green-Blue). We can replicate this behavior with a custom method as follows:

public int getIntFromColor(int Red, int Green, int Blue){
    Red = (Red << 16) & 0x00FF0000; //Shift red 16-bits and mask out other stuff
    Green = (Green << 8) & 0x0000FF00; //Shift Green 8-bits and mask out other stuff
    Blue = Blue & 0x000000FF; //Mask out anything not blue.

    return 0xFF000000 | Red | Green | Blue; //0xFF000000 for 100% Alpha. Bitwise OR everything together.
}

This assumes you can somehow retrieve the individual red, green and blue colour components and that all the values you passed in for the colours are 0-255.

If your RGB values are in form of a float percentage between 0 and 1 consider the following method:

public int getIntFromColor(float Red, float Green, float Blue){
    int R = Math.round(255 * Red);
    int G = Math.round(255 * Green);
    int B = Math.round(255 * Blue);

    R = (R << 16) & 0x00FF0000;
    G = (G << 8) & 0x0000FF00;
    B = B & 0x000000FF;

    return 0xFF000000 | R | G | B;
}

As others have stated, if you're using a standard java object, just use getRGB();

If you decide to use the android color class properly you can also do:

int RGB = android.graphics.Color.argb(255, Red, Green, Blue); //Where Red, Green, Blue are the RGB components. The number 255 is for 100% Alpha

or

int RGB = android.graphics.Color.rgb(Red, Green, Blue); //Where Red, Green, Blue are the RGB components.

as others have stated... (Second function assumes 100% alpha)

Both methods basically do the same thing as the first method created above.

If table_2 is empty, then try the following insert statement:

insert into table_2 (itemid,location1) 
select itemid,quantity from table_1 where locationid=1

If table_2 already contains the itemid values, then try this update statement:

update table_2 set location1=
(select quantity from table_1 where locationid=1 and table_1.itemid = table_2.itemid)

There are two things to remember here. One is to add the -PassThru argument and two is to add the -Wait argument. You need to add the wait argument because of this defect: http://connect.microsoft.com/PowerShell/feedback/details/520554/start-process-does-not-return-exitcode-property

-PassThru [<SwitchParameter>]
    Returns a process object for each process that the cmdlet started. By d
    efault, this cmdlet does not generate any output.

Once you do this a process object is passed back and you can look at the ExitCode property of that object. Here is an example:

$process = start-process ping.exe -windowstyle Hidden -ArgumentList "-n 1 -w 127.0.0.1" -PassThru -Wait
$process.ExitCode

# This will print 1

If you run it without -PassThru or -Wait, it will print out nothing.

The same answer is here: How do I run a Windows installer and get a succeed/fail value in PowerShell?

Closed connection in another client

In my case, the error was:

java.net.SocketException: Software caused connection abort: recv failed

It was received in eclipse while debugging a java application accessing a H2 database. The source of the error was that I had initially opened the database with SQuirreL to check manually for integrity. I did use the flag to enable multiple connections to the same DB (i.e. AUTO_SERVER=TRUE), so there was no problem connecting to the DB from java.

The error appeared when, after a while --it is a long java process-- I decided to close SQuirreL to free resources. It appears as if SQuirreL were the one "owning" the DB server instance and that it was shut down with the SQuirreL connection.

Restarting the Java application did not yield the error again.

Setting the User Agent in PhantomJS

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
...
caps = DesiredCapabilities.PHANTOMJS
caps["phantomjs.page.settings.userAgent"] = "whatever you want"
driver = webdriver.PhantomJS(desired_capabilities=caps)

The only minor issue is that, unlike for Firefox and Chrome, this does not return your custom setting:

driver.execute_script("return navigator.userAgent")

So, if anyone figures out how to do that in PhantomJS, please edit my answer or add a comment below! Cheers.

If you are a beginner, it is better you first go through some basic tutorials and after that learn about naming conventions. I have gone through the following to learn Angular, some of which are very effective.

Tutorials :

1. http://www.toptal.com/angular-js/a-step-by-step-guide-to-your-first-angularjs-app
2. http://viralpatel.net/blogs/angularjs-controller-tutorial/
3. http://www.angularjstutorial.com/

Details of application structure and naming conventions can be found in a variety of places. I've gone through 100's of sites and I think these are among the best:

• https://github.com/camronlevanger/AngularJS-Guide
• https://github.com/mgechev/angularjs-style-guide
• https://google.github.io/styleguide/angularjs-google-style.html

The best solution would be handle with the event through a javascript function, but in order to use a simple and quick solution using the html element directly, and once that the "event" and "window.event" are deprecated and not universally supported (https://developer.mozilla.org/en-US/docs/Web/API/Window/event), I suggest the following "hard code":

<div onclick="alert('blablabla'); (arguments[0] ? arguments[0].stopPropagation() : false);">...</div>

The answers above are good, but I'd like to flesh them out with a few more tips:

If you want to modify the title of the back button (the arrow-y looking one at the left of the navigation bar) you MUST do it in the PREVIOUS view controller, not the one for which it will display. It's like saying "hey, if you ever push another view controller on top of this one, call the back button "Back" (or whatever) instead of the default."

If you want to hide the back button during a special state, such as while a UIPickerView is displayed, use self.navigationItem.hidesBackButton = YES; and remember to set it back when you leave the special state.

If you want to display one of the special symbolic buttons, use the form initWithBarButtonSystemItem:target:action with a value like UIBarButtonSystemItemAdd

Remember, the meaning of that symbol is up to you, but be careful of the Human Interface Guidelines. Using UIBarButtonSystemItemAdd to mean deleting an item will probably get your application rejected.

$count = DB::table('category_issue')->count();

will give you the number of items.

For more detailed information check Fluent Query Builder section in beautiful Laravel Documentation.

Here is another way to use SQL SELECT statement in VBA:

 sSQL = "SELECT Variable FROM GroupTable WHERE VariableCode = '" & Me.comboBox & "'" 
 Set rs = CurrentDb.OpenRecordset(sSQL)
 On Error GoTo resultsetError 
 dbValue = rs!Variable
 MsgBox dbValue, vbOKOnly, "RS VALUE"
resultsetError:
 MsgBox "Error Retrieving value from database",VbOkOnly,"Database Error"

In Kotlin, add a listener to your listView as simple as java

your_listview.setOnItemClickListener { parent, view, position, id ->   

    Toast.makeText(this, position, Toast.LENGTH_SHORT).show()

 }

Open the Terminal and run

 mysql -u root -p

Password is null or just enter your mysql password

Ater Just Run This Query

 DROP DATABASE DBname;

If you are using phpmyadmin then just run

 DROP DATABASE DBname;

i improved the solutions of RHTs/Brad Ms and of Lestos answer.

i extended both solutions in leaving the state there, where it was found. So i save the current ResultSet position and restore it after i created the maps.

The rs is the ResultSet, its a field variable and so in my solutions-snippets not visible.

I replaced the specific Map in Brad Ms solution to the gerneric Map.

    public List<Map<String, Object>> resultAsListMap() throws SQLException
    {
        var md = rs.getMetaData();
        var columns = md.getColumnCount();
        var list = new ArrayList<Map<String, Object>>();

        var currRowIndex = rs.getRow();
        rs.beforeFirst();

        while (rs.next())
        {
            HashMap<String, Object> row = new HashMap<String, Object>(columns);
            for (int i = 1; i <= columns; ++i)
            {
                row.put(md.getColumnName(i), rs.getObject(i));
            }

            list.add(row);
        }

        rs.absolute(currRowIndex);

        return list;
    }

In Lestos solution, i optimized the code. In his code he have to lookup the Maps each iteration of that for-loop. I reduced that to only one array-acces each for-loop iteration. So the program must not seach each iteration step for that string-key.

    public Map<String, List<Object>> resultAsMapList() throws SQLException
    {
        var md = rs.getMetaData();
        var columns = md.getColumnCount();
        var tmp = new ArrayList[columns];
        var map = new HashMap<String, List<Object>>(columns);

        var currRowIndex = rs.getRow();
        rs.beforeFirst();

        for (int i = 1; i <= columns; ++i)
        {
            tmp[i - 1] = new ArrayList<>();
            map.put(md.getColumnName(i), tmp[i - 1]);
        }

        while (rs.next())
        {
            for (int i = 1; i <= columns; ++i)
            {
                tmp[i - 1].add(rs.getObject(i));
            }
        }

        rs.absolute(currRowIndex);

        return map;
    }

My preferred method is to actually fix the library rather than playing with environment variables that may or may not actually be in scope depending on how the application is run. This is actually a fairly simple process.

First, look at the error output to see where the offending python module is located:

ImportError: dlopen(/Library/Python/2.7/site-packages/_mysql.so, 2): Library not loaded: libmysqlclient.18.dylib Referenced from: /Library/Python/2.7/site-packages/_mysql.so Reason: image not found

Okay, so the offending file is /Library/Python/2.7/site-packages/_mysql.so

Next, figure out where _mysql.so thinks it should find libmysqlclient.18.dylib:

% otool -L /Library/Python/2.7/site-packages/_mysql.so
/Library/Python/2.7/site-packages/_mysql.so:
    libmysqlclient.18.dylib (compatibility version 18.0.0, current version 18.0.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 169.3.0)

So, it's looking for libmysqlclient.18.dylib with no path information, let's fix that:

% sudo install_name_tool -change libmysqlclient.18.dylib /usr/local/mysql/lib/libmysqlclient.18.dylib /Library/Python/2.7/site-packages/_mysql.so

Now _mysql.so knows the full path to the library and everything works, regardless of environment variables.

% otool -L /Library/Python/2.7/site-packages/_mysql.so                                                                                           
/Library/Python/2.7/site-packages/_mysql.so:
    /usr/local/mysql/lib/libmysqlclient.18.dylib (compatibility version 18.0.0, current version 18.0.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 169.3.0)

The following does it in a single line:

dataTable.Rows.OfType<DataRow>()
    .Select(dr => dr.Field<MyType>(columnName)).ToList();

[Edit: Add a reference to System.Data.DataSetExtensions to your project if this does not compile]

Shared Preferences is so easy to learn, so take a look on this simple tutorial about sharedpreference

import android.os.Bundle;
import android.preference.PreferenceActivity;

    public class UserSettingActivity extends PreferenceActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

      addPreferencesFromResource(R.xml.settings);

    }
}

You can add escaped double quotes like this: String name = "\"john\"";

Just an update on more current OS's (Vista, Win7, etc.) - the temp file path has changed may be different based on several variables. The items below are not definitive, however, they are a few I have encountered:

"temp" environment variable setting - then it would be:

%temp%\Temporary ASP.NET Files

Permissions and what application/process (VS, IIS, IIS Express) is running the .Net compiler. Accessing the C:\WINDOWS\Microsoft.NET\Framework folders requires elevated permissions and if you are not developing under an account with sufficient permissions then this folder might be used:

c:\Users\[youruserid]\AppData\Local\Temp\Temporary ASP.NET Files

There are also cases where the temp folder can be set via config for a machine or site specific using this:

<compilation tempDirectory="d:\MyTempPlace" />

I even have a funky setup at work where we don't run Admin by default, plus the IT guys have login scripts that set %temp% and I get temp files in 3 different locations depending on what is compiling things! And I'm still not certain about how these paths get picked....sigh.

Still, dthrasher is correct, you can just delete these and VS and IIS will just recompile them as needed.

     CountDownTimer waitTimer;
     waitTimer = new CountDownTimer(60000, 300) {

       public void onTick(long millisUntilFinished) {
          //called every 300 milliseconds, which could be used to
          //send messages or some other action
       }

       public void onFinish() {
          //After 60000 milliseconds (60 sec) finish current 
          //if you would like to execute something when time finishes          
       }
     }.start();

to stop the timer early:

     if(waitTimer != null) {
         waitTimer.cancel();
         waitTimer = null;
     }

I had the same problem when I was debugging my app. I've rewrote the hash that you have crossed out in the attached image (the one that Facebook says is invalid) and added it in the Facebook's developers console to key hashes. Just be careful of typos.

This solution is more like an easy workaround than a proper solution.

Its Solution is very Simple!

There are Three Basic Reasons for This problem

1. You are doing Heavy / Long running / Complex task in onCreateVeiw Function.
2. If your are using Thread. Then Thread Sleep time may be very large.
3. If You are using any Third Party library. Which is initialize at app start up time it may leads this problem.

Solutions:

Solution 1:

  Remove the Heavy Task from onCreateView() function and place it some where appropriate place.

Solution 2:

  Reduce the Thread Sleep time.

Solution 3:

  Remove the Third party library at app initialize at implement them with some good strategy.

In my Case i am using Sugar ORM which leads this problem.

You can still use the Authorization header with OAuth 2.0. There is a Bearer type specified in the Authorization header for use with OAuth bearer tokens (meaning the client app simply has to present ("bear") the token). The value of the header is the access token the client received from the Authorization Server.

It's documented in this spec: https://tools.ietf.org/html/rfc6750#section-2.1

E.g.:

   GET /resource HTTP/1.1
   Host: server.example.com
   Authorization: Bearer mF_9.B5f-4.1JqM

Where mF_9.B5f-4.1JqM is your OAuth access token.

If your cer file has binary format you must convert it by

Whatever method you choose is not freeing you from performing the same validation on at the back end.

I think you need to put it under src/main/resources and load it as follows:

props.load(new FileInputStream("src/main/resources/myconf.properties"));

The way you are trying to load it will first check in base folder of your project. If it is in target/classes and you want to load it from there do the following:

props.load(new FileInputStream("target/classes/myconf.properties"));

Since I wanted to compare two arrays for a unit Test and I arrived on this answer I thought I could share.

You can also do it with:

@Test
public void testTwoArrays() {
  byte[] array = new BigInteger("1111000011110001", 2).toByteArray();
  byte[] secondArray = new BigInteger("1111000011110001", 2).toByteArray();

  Assert.assertArrayEquals(array, secondArray);
}

And you could check on Comparing arrays in JUnit assertions for more infos.

There is no need for jQuery here, regular JavaScript will do:

var str = "Abc: Lorem ipsum sit amet";
str = str.substring(str.indexOf(":") + 1);

Or, the .split() and .pop() version:

var str = "Abc: Lorem ipsum sit amet";
str = str.split(":").pop();

Or, the regex version (several variants of this):

var str = "Abc: Lorem ipsum sit amet";
str = /:(.+)/.exec(str)[1];

Other answers provide pretty concise answer to this, without one important fact: You don't need to implement fixed point combinator in any practical language in this convoluted way and doing so serves no practical purpose (except "look, I know what Y-combinator is"). It's important theoretical concept, but of little practical value.

Well if you want to find a perfect XHTML+CSS to PDF converter library, forget it. It's far from possible. Because it's just like finding a perfect browser (XHTML+CSS rendering engine). Do we have one? IE or FF?

I have had some success with DOMPDF. The thing is that you have to modify your HTML+CSS code to go with the way the library is meant to work. Other than that, I have pretty good results.

See below:

To change the character set encoding to UTF-8 for the database itself, type the following command at the mysql> prompt. USE ALTER DATABASE.. Replace DBNAME with the database name:

ALTER DATABASE DBNAME CHARACTER SET utf8 COLLATE utf8_general_ci;

This is a duplicate of this question How to convert an entire MySQL database characterset and collation to UTF-8?

The server might have multiple IP addresses that it is listening on. If your connection has the VIEW SERVER STATE server permission granted to it, you can run this query to get the address you have connected to SQL Server:

SELECT dec.local_net_address
FROM sys.dm_exec_connections AS dec
WHERE dec.session_id = @@SPID;

This solution does not require you to shell out to the OS via xp_cmdshell, which is a technique that should be disabled (or at least strictly secured) on a production server. It may require you to grant VIEW SERVER STATE to the appropriate login, but that is a far smaller security risk than running xp_cmdshell.

The technique mentioned by GilM for the server name is the preferred one:

SELECT SERVERPROPERTY(N'MachineName');

For me, I had to remove the intellij internal sdk and started to use my local sdk. When I started to use the internal, the error was gone.

You can use Apache commons-io for this task:

Refer to this method:

public static byte[] readFileToByteArray(File file) throws IOException

Update:

Java 7 way:

byte[] bytes = Files.readAllBytes(Paths.get(filename));

and if it is a text file and you want to convert it to String (change encoding as needed):

StandardCharsets.UTF_8.decode(ByteBuffer.wrap(bytes)).toString()

If you want to add two columns together, all you have to do is add them. Then you will get the sum of those two columns for each row returned by the query.

What your code is doing is adding the two columns together and then getting a sum of the sums. That will work, but it might not be what you are attempting to accomplish.

In order to get behavior for match_parent and wrap_content we need to use mainAxisSize property in Row/Column widget, the mainAxisSize property takes MainAxisSize enum having two values which is MainAxisSize.min which behaves as wrap_content and MainAxisSize.max which behaves as match_parent.

To open docs automatically in Chrome without them being saved;

1. Go to the the three vertical dots on your top far right corner in Chrome.

2. Scroll down to Settings and click.

3. Scroll down to Show advance settings...

4. Scroll down to Downloads under Download location: click the Change button and chose tmp folder. Then just close the screen.

5. Click on any attachments and a small box to the left will appear, it should automatically open if you click on it.

6. When the bottom left box appears it will contain an arrow; click on it and choose the option "Always open files of this type". Going forward it will open the file instantly instead of the small box appearing to the left and you having to click on it to open. You will have to do it just once for various files such PDF, Excel 2010, Excel 2013 Word, ect.

An old post, but I was surprised about the most up-voted answer.

The proper solution for this should be to cancel the asynctask in onStop (or wherever appropriate in your fragment). This way you don't introduce a memory leak (an asynctask keeping a reference to your destroyed fragment) and you have better control of what is going on in your fragment.

@Override
public void onStop() {
    super.onStop();
    mYourAsyncTask.cancel(true);
}

I was searching to get a result for this either and I ended up with;

const MyObject = {
    SubObject: {
        'eu': [0, "asd", true, undefined],
        'us': [0, "asd", false, null],
        'aus': [0, "asd", false, 0]
    }
};

For those who wanted the result as a string:

Object.keys(MyObject.SubObject).toString()

output: "eu,us,aus"

For those who wanted the result as an array:

Array.from(Object.keys(MyObject))

output: Array ["eu", "us", "aus"]

For those who are looking for a "contains" type method: as numeric result:

console.log(Object.keys(MyObject.SubObject).indexOf("k"));

output: -1

console.log(Object.keys(MyObject.SubObject).indexOf("eu"));

output: 0

console.log(Object.keys(MyObject.SubObject).indexOf("us"));

output: 3

as boolean result:

console.log(Object.keys(MyObject.SubObject).includes("eu"));

output: true

In your case;

var myVar = { typeA: { option1: "one", option2: "two" } }_x000D_
_x000D_
    // Example 1_x000D_
    console.log(Object.keys(myVar.typeA).toString()); // Result: "option1, option2"_x000D_
_x000D_
    // Example 2_x000D_
    console.log(Array.from(Object.keys(myVar.typeA))); // Result: Array ["option1", "option2" ]_x000D_
    _x000D_
    // Example 3 as numeric_x000D_
    console.log((Object.keys(myVar.typeA).indexOf("option1")>=0)?'Exist!':'Does not exist!'); // Result: Exist!_x000D_
    _x000D_
    // Example 3 as boolean_x000D_
    console.log(Object.keys(myVar.typeA).includes("option2")); // Result: True!_x000D_
    _x000D_
    // if you would like to know about SubObjects_x000D_
    for(var key in myVar){_x000D_
      // do smt with SubObject_x000D_
      console.log(key); // Result: typeA_x000D_
    }_x000D_
_x000D_
    // if you already know your "SubObject"_x000D_
    for(var key in myVar.typeA){_x000D_
      // do smt with option1, option2_x000D_
      console.log(key); // Result: option1 // Result: option2_x000D_
    }

You can always get your runtime path by using:

 String path = new File(".").getCanonicalPath();

This provides valuable information about where to put files and resources.

I believe that a much more reliable way to detect mobile devices is to look at the navigator.userAgent string. For example, on my iPhone the user agent string is:

Mozilla/5.0 (iPhone; CPU iPhone OS 10_3_2 like Mac OS X) AppleWebKit/603.2.4 (KHTML, like Gecko) Version/10.0 Mobile/14F89 Safari/602.1

Note that this string contains two telltale keywords: iPhone and Mobile. Other user agent strings for devices that I don't have are provided at:

https://deviceatlas.com/blog/list-of-user-agent-strings

Using this string, I set a JavaScript Boolean variable bMobile on my website to either true or false using the following code:

var bMobile =   // will be true if running on a mobile device
  navigator.userAgent.indexOf( "Mobile" ) !== -1 || 
  navigator.userAgent.indexOf( "iPhone" ) !== -1 || 
  navigator.userAgent.indexOf( "Android" ) !== -1 || 
  navigator.userAgent.indexOf( "Windows Phone" ) !== -1 ;

the path you are using is not correct you could just open the node_module and find the path of font-awesome. use could use js or svg font but i prefer the css style.

at first use this command to install font-awesome-free npm install --save-dev @fortawesome/fontawesome-free

after that you can do this

@import "~@fortawesome/fontawesome-free/scss/fontawesome";
@import "~@fortawesome/fontawesome-free/scss/regular";
@import "~@fortawesome/fontawesome-free/scss/solid";
@import "~@fortawesome/fontawesome-free/scss/brands";

and I copy the font path like below this is optional

.copy('node_modules/@fortawesome/fontawesome-free/webfonts', 'public/fonts');

and finally just run the script npm run dev or npm run watch in laravel

The Major Difference between a Service and an IntentService is described as follows:

Service :

1.A Service by default, runs on the application's main thread.(here no default worker thread is available).So the user needs to create a separate thread and do the required work in that thread.

2.Allows Multiple requests at a time.(Multi Threading)

IntentService :

1.Now, coming to IntentService, here a default worker thread is available to perform any operation. Note that - You need to implement onHandleIntent() method ,which receives the intent for each start request, where you can do the background work.

2.But it allows only one request at a time.

sp_executesql is more likely to promote query plan reuse. When using sp_executesql, parameters are explicitly identified in the calling signature. This excellent article descibes this process.

Don't pass the result of swapImages to setInterval by invoking it. Just pass the function, like this:

setInterval(swapImages, 1000);

If none of the above works,

try commenting out the line

SetHandler ....

and restart apache using

/etc/init.d/httpd restart

It should work!

import sys
sys.exit()

The code below worked in Ubuntu 14.04. Try before you use it in other versions/linux variants.

# set password
echo "newuser:newpassword" | chpasswd

I was having same kind of problem with ldap, intl, curl php extensions. I've solved those issues by the following ways:

At first you've to check whether these extensions have been enabled in the php.ini file by removing semicolon (;) in front of the following lines:

;extension=php_intl.dll
;extension=php_ldap.dll
;extension=php_curl.dll

Secondly, libeay32.dll, ibssh2.dll and ssleay32.dll files have to be loaded by php properly to function those extensions properly. These dll files are required by several php extensions (ie curl, ldap, intl etc). These files generally reside in the php installation directory [for my case it is C:\php directory]. Additionally, for intl extension to be enabled you're gonna need some other dll files to be loaded by php properly. The name of these files begin with icu (ie icudt57.dll icuin57.dll etc for php version 5.6). You'll also find these files in the php main installation directory.

There is a alternate way you can load these files from your httpd.conf (apache configuratio file) file instead of copying them to the apache's bin directory. This can be done by using the following technique:

Please note that my php version is 5.5.

LoadFile  "C:/php/icudt51.dll"
LoadFile  "C:/php/icuin51.dll"
LoadFile  "C:/php/icuio51.dll"
LoadFile  "C:/php/icule51.dll"
LoadFile  "C:/php/iculx51.dll"
LoadFile  "C:/php/icutest51.dll"
LoadFile  "C:/php/icutu51.dll"
LoadFile  "C:/php/icuuc51.dll"

LoadFile  "C:/php/libeay32.dll"
LoadFile  "C:/php/libssh2.dll"
LoadFile  "C:/php/ssleay32.dll"

 That's it.

You could have a redirect servlet. In you web.xml you'd have:

<servlet>
    <servlet-name>images</servlet-name>
    <servlet-class>com.example.images.ImageServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>images</servlet-name>
    <url-pattern>/images/*</url-pattern>
</servlet-mapping>

All your images would be in "/images", which would be intercepted by the servlet. It would then read in the relevant file in whatever folder and serve it right back out. For example, say you have a gif in your images folder, c:\Server_Images\smilie.gif. In the web page would be <img src="http:/example.com/app/images/smilie.gif".... In the servlet, HttpServletRequest.getPathInfo() would yield "/smilie.gif". Which the servlet would find in the folder.

Python string comparison is lexicographic:

From Python Docs: http://docs.python.org/reference/expressions.html

Strings are compared lexicographically using the numeric equivalents (the result of the built-in function ord()) of their characters. Unicode and 8-bit strings are fully interoperable in this behavior.

Hence in your example, 'abc' < 'bac', 'a' comes before (less-than) 'b' numerically (in ASCII and Unicode representations), so the comparison ends right there.

You can use an anonymous function to pass the matches to your function:

$result = preg_replace_callback(
    "/\{([<>])([a-zA-Z0-9_]*)(\?{0,1})([a-zA-Z0-9_]*)\}(.*)\{\\1\/\\2\}/isU",
    function($m) { return CallFunction($m[1], $m[2], $m[3], $m[4], $m[5]); },
    $result
);

Apart from being faster, this will also properly handle double quotes in your string. Your current code using /e would convert a double quote " into \".

using cast instead of recast (note 'Frequency' is now 'value')

df  <- data.frame(Category = c("First","First","First","Second","Third","Third","Second")
                  , value = c(10,15,5,2,14,20,3))

install.packages("reshape")

result<-cast(df, Category ~ . ,fun.aggregate=sum)

to get:

Category (all)
First     30
Second    5
Third     34

The best option for your specific case might be:

Right before your close </body> tag:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script>window.jQuery || document.write('<script src="js/vendor/jquery-1.10.2.min.js"><\/script>')</script>

This is probably the easiest way given that your issue is centered around jQuery.

If you wanted a more robust solution you could try:

var online = navigator.onLine;

Read more about the W3C's spec on offline web apps, however be aware that this will work best in modern web browsers, doing so with older web browsers may not work as expected, or at all.

Alternatively, an XHR request to your own server isn't that bad of a method for testing your connectivity. Considering one of the other answers state that there are too many points of failure for an XHR, if your XHR is flawed when establishing it's connection then it'll also be flawed during routine use anyhow. If your site is unreachable for any reason, then your other services running on the same servers will likely be unreachable also. That decision is up to you.

I wouldn't recommend making an XHR request to someone else's service, even google.com for that matter. Make the request to your server, or not at all.

What does it mean to be "online"?

There seems to be some confusion around what being "online" means. Consider that the internet is a bunch of networks, however sometimes you're on a VPN, without access to the internet "at-large" or the world wide web. Often companies have their own networks which have limited connectivity to other external networks, therefore you could be considered "online". Being online only entails that you are connected to a network, not the availability nor reachability of the services you are trying to connect to.

To determine if a host is reachable from your network, you could do this:

function hostReachable() {

  // Handle IE and more capable browsers
  var xhr = new ( window.ActiveXObject || XMLHttpRequest )( "Microsoft.XMLHTTP" );

  // Open new request as a HEAD to the root hostname with a random param to bust the cache
  xhr.open( "HEAD", "//" + window.location.hostname + "/?rand=" + Math.floor((1 + Math.random()) * 0x10000), false );

  // Issue request and handle response
  try {
    xhr.send();
    return ( xhr.status >= 200 && (xhr.status < 300 || xhr.status === 304) );
  } catch (error) {
    return false;
  }

}

You can also find the Gist for that here: https://gist.github.com/jpsilvashy/5725579

Details on local implementation

Some people have commented, "I'm always being returned false". That's because you're probably testing it out on your local server. Whatever server you're making the request to, you'll need to be able to respond to the HEAD request, that of course can be changed to a GET if you want.

If you install the Tortoise SVN, Please go to task manager and stop it. Then try to delete the folder. it will work

I would change your service layer to:

public Task<BackOfficeResponse<List<Country>>> ReturnAllCountries()
{
    return Task.Run(() =>
    {
        return _service.Process<List<Country>>(BackOfficeEndpoint.CountryEndpoint, "returnCountries");
    }      
}

as you have it, you are still running your _service.Process call synchronously, and gaining very little or no benefit from awaiting it.

With this approach, you are wrapping the potentially slow call in a Task, starting it, and returning it to be awaited. Now you get the benefit of awaiting the Task.

XCode 8.1, Swift 3

import UIKit
class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        UISegmentedControl.appearance().setTitleTextAttributes(NSDictionary(objects: [UIFont.systemFont(ofSize: 24.0)], 
        forKeys: [NSFontAttributeName as NSCopying]) as? [AnyHashable : Any], 
        for: UIControlState.normal)
    }
}

just change the number value (ofSize: 24.0)

That specifies the how many digits you want it to show.

integer value or * that specifies minimum field width. The result is padded with space characters (by default), if required, on the left when right-justified, or on the right if left-justified. In the case when * is used, the width is specified by an additional argument of type int. If the value of the argument is negative, it results with the - flag specified and positive field width.

You can specify a callback function:

$(selector).fadeOut('slow', function() {
    // will be called when the element finishes fading out
    // if selector matches multiple elements it will be called once for each
});

Documentation here.

So You want to write data to a file, but only if it doesn’t already exist?.

This problem is easily solved by using the little-known x mode to open() instead of the usual w mode. For example:

 >>> with open('somefile', 'wt') as f:
 ...     f.write('Hello\n')
...
>>> with open('somefile', 'xt') as f:
...     f.write('Hello\n')
...
 Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
FileExistsError: [Errno 17] File exists: 'somefile'
  >>>

If the file is binary mode, use mode xb instead of xt.

HAVING specifies a search condition for a group or an aggregate function used in SELECT statement.

You're probably out of luck without some hack-y workarounds

You could try

onClick={(event: React.MouseEvent<HTMLElement>) => {
 makeMove(ownMark, (event.target as any).index)
}}

I'm not sure how strict your linter is - that might shut it up just a little bit

I played around with it for a bit, and couldn't figure it out, but you can also look into writing your own augmented definitions: https://www.typescriptlang.org/docs/handbook/declaration-merging.html

HTML are markup languages, basically they are set of tags like <html>, <body>, which is used to present a website using css, and javascript as a whole. All these, happen in the clients system or the user you will be browsing the website.

Now, Connecting to a database, happens on whole another level. It happens on server, which is where the website is hosted.

So, in order to connect to the database and perform various data related actions, you have to use server-side scripts, like php, jsp, asp.net etc.

Now, lets see a snippet of connection using MYSQLi Extension of PHP

$db = mysqli_connect('hostname','username','password','databasename');

This single line code, is enough to get you started, you can mix such code, combined with HTML tags to create a HTML page, which is show data based pages. For example:

<?php
    $db = mysqli_connect('hostname','username','password','databasename');
?>
<html>
    <body>
          <?php
                $query = "SELECT * FROM `mytable`;";
                $result = mysqli_query($db, $query);
                while($row = mysqli_fetch_assoc($result)) {
                      // Display your datas on the page
                }
          ?>
    </body>
</html>

In order to insert new data into the database, you can use phpMyAdmin or write a INSERT query and execute them.

Json has to have key-value pairs. Tho you can still have an array as the value part. Thus add a "key" of your chousing:

var json = JSON.stringify({whatver: test});

Let me assume that your data.frame is a mix of different datatypes and not all columns need to be modified.

to modify only columns 12 to 18 (of the total 21), just do this

df[, 12:18][df[, 12:18] == 0] <- NA

Here's something based on Jerub's "naive approach" (naive being his words, not mine!):

import string
ALLOWED = frozenset(string.ascii_letters + string.digits + '_' + '-')

def check(mystring):
    return all(c in ALLOWED for c in mystring)

If ALLOWED was a string then I think c in ALLOWED would involve iterating over each character in the string until it found a match or reached the end. Which, to quote Joel Spolsky, is something of a Shlemiel the Painter algorithm.

But testing for existence in a set should be more efficient, or at least less dependent on the number of allowed characters. Certainly this approach is a little bit faster on my machine. It's clear and I think it performs plenty well enough for most cases (on my slow machine I can validate tens of thousands of short-ish strings in a fraction of a second). I like it.

ACTUALLY on my machine a regexp works out several times faster, and is just as simple as this (arguably simpler). So that probably is the best way forward.

All you need is to create two layouts:

1. an empty layout

2. main layout

Then write the code below in _viewStart file:

@{
   if (Request.IsAjaxRequest())
   {
      Layout = "~/Areas/Dashboard/Views/Shared/_emptyLayout.cshtml";
   }
   else
   {
      Layout = "~/Areas/Dashboard/Views/Shared/_Layout.cshtml";
   }
 }

of course, maybe it is not the best solution

datetime.strptime is the main routine for parsing strings into datetimes. It can handle all sorts of formats, with the format determined by a format string you give it:

from datetime import datetime

datetime_object = datetime.strptime('Jun 1 2005  1:33PM', '%b %d %Y %I:%M%p')

The resulting datetime object is timezone-naive.

Links:

• Python documentation for strptime: Python 2, Python 3

• Python documentation for strptime/strftime format strings: Python 2, Python 3

• strftime.org is also a really nice reference for strftime

Notes:

• strptime = "string parse time"
• strftime = "string format time"
• Pronounce it out loud today & you won't have to search for it again in 6 months.

If you still get the exception in the server startup after changing listen port, you should try changing Pointbase server port and debug port in setDomainEnv.cmd

This didn't work for me, I want to match ?b as the b parameter is present, and not match ?return as the r parameter, here is my solution.

window.query_param = function(name) {
  var param_value, params;

  params = location.search.replace(/^\?/, '');
  params = _.map(params.split('&'), function(s) {
    return s.split('=');
  });

  param_value = _.select(params, function(s) {
    return s.first === name;
  })[0];

  if (param_value) {
    return decodeURIComponent(param_value[1] || '');
  } else {
    return null;
  }
};

All of these answers miss one important point -- the n'th line is the n'th line in the file, and not the n'th row in the dataset. I have a situation where I download some antiquated stream gauge data from the USGS. The head of the dataset is commented with '#', the first line after that are the labels, next comes a line that describes the date types, and last the data itself. I never know how many comment lines there are, but I know what the first couple of rows are. Example:

----------------------------- WARNING ----------------------------------

Some of the data that you have obtained from this U.S. Geological Survey database

may not have received Director's approval. ... agency_cd site_no datetime tz_cd 139719_00065 139719_00065_cd

5s 15s 20d 6s 14n 10s USGS 08041780 2018-05-06 00:00 CDT 1.98 A

It would be nice if there was a way to automatically skip the n'th row as well as the n'th line.

As a note, I was able to fix my issue with:

import pandas as pd
ds = pd.read_csv(fname, comment='#', sep='\t', header=0, parse_dates=True)
ds.drop(0, inplace=True)

You can do something like this (taken from here):

import java.awt.FlowLayout;

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JTextField;
import javax.swing.text.AttributeSet;
import javax.swing.text.BadLocationException;
import javax.swing.text.PlainDocument;

class JTextFieldLimit extends PlainDocument {
  private int limit;
  JTextFieldLimit(int limit) {
    super();
    this.limit = limit;
  }

  JTextFieldLimit(int limit, boolean upper) {
    super();
    this.limit = limit;
  }

  public void insertString(int offset, String str, AttributeSet attr) throws BadLocationException {
    if (str == null)
      return;

    if ((getLength() + str.length()) <= limit) {
      super.insertString(offset, str, attr);
    }
  }
}

public class Main extends JFrame {
  JTextField textfield1;

  JLabel label1;

  public void init() {
    setLayout(new FlowLayout());
    label1 = new JLabel("max 10 chars");
    textfield1 = new JTextField(15);
    add(label1);
    add(textfield1);
    textfield1.setDocument(new JTextFieldLimit(10));

    setSize(300,300);
    setVisible(true);
  }
}

Edit: Take a look at this previous SO post. You could intercept key press events and add/ignore them according to the current amount of characters in the textfield.

Use NEQ instead.

if "asdf" NEQ "fdas" echo asdf

CR - ASCII code 13

LF - ASCII code 10.

Theoretically CR returns cursor to the first position (on the left). LF feeds one line moving cursor one line down. This is how in old days you controled printers and text-mode monitors. These characters are usually used to mark end of lines in text files. Different operating systems used different conventions. As you pointed out Windows uses CR/LF combination while pre-OSX Macs use just CR and so on.

2. Use checkout if you want to discard changes to unstaged file/s.

What you want cannot be done, because plt.legend() places a legend in the current axes, in your case in the last one.

If, on the other hand, you can be content with placing a comprehensive legend in the last subplot, you can do like this

f, (ax1, ax2, ax3) = plt.subplots(3, sharex=True, sharey=True)
l1,=ax1.plot(x,y, color='r', label='Blue stars')
l2,=ax2.plot(x,y, color='g')
l3,=ax3.plot(x,y, color='b')
ax1.set_title('2012/09/15')
plt.legend([l1, l2, l3],["HHZ 1", "HHN", "HHE"])
plt.show()

Note that you pass to legend not the axes, as in your example code, but the lines as returned by the plot invocation.

PS

Of course you can invoke legend after each subplot, but in my understanding you already knew that and were searching for a method for doing it at once.

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

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

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

Try this:

((.|\n)*)<FooBar>

It basically says "any character or a newline" repeated zero or more times.

This should work:

int hh, mm, ss;
struct tm when = {0};

sscanf_s(date, "%d:%d:%d", &hh, &mm, &ss);

There's a package that's dedicated to this specifically:

from thesmuggler import smuggle

# À la `import weapons`
weapons = smuggle('weapons.py')

# À la `from contraband import drugs, alcohol`
drugs, alcohol = smuggle('drugs', 'alcohol', source='contraband.py')

# À la `from contraband import drugs as dope, alcohol as booze`
dope, booze = smuggle('drugs', 'alcohol', source='contraband.py')

I recommend rbenv* https://github.com/rbenv/rbenv

* If this meets your criteria: https://github.com/rbenv/rbenv/wiki/Why-rbenv?:

rbenv does…

• Provide support for specifying application-specific Ruby versions.
• Let you change the global Ruby version on a per-user basis.
• Allow you to override the Ruby version with an environment variable.

In contrast with RVM, rbenv does not…

• Need to be loaded into your shell. Instead, rbenv's shim approach works by adding a directory to your $PATH.
• Override shell commands like cd or require prompt hacks. That's dangerous and error-prone.
• Have a configuration file. There's nothing to configure except which version of Ruby you want to use.
• Install Ruby. You can build and install Ruby yourself, or use ruby-build to automate the process.
• Manage gemsets. Bundler is a better way to manage application dependencies. If you have projects that are not yet using Bundler you can install the rbenv-gemset plugin.
• Require changes to Ruby libraries for compatibility. The simplicity of rbenv means as long as it's in your $PATH, nothing else needs to know about it.

INSTALLATION

Install Homebrew http://brew.sh

Then:

$ brew update
$ brew install rbenv 
$ brew install rbenv ruby-build

# Add rbenv to bash so that it loads every time you open a terminal
echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.bash_profile
source ~/.bash_profile

UPDATE
There's one additional step after brew install rbenv Run rbenv init and add one line to .bash_profile as it states. After that reopen your terminal window […] SGI Sep 30 at 12:01 —https://stackoverflow.com/users/119770

MySQLI example where $con is the database connection variable and table name is: mytable.

mysqli_query($con,'TRUNCATE TABLE mytable');

I noticed that if you have divisions it rounds off to integer, it would be better to use:

c=float(max(a1,...,an))/b

Sorry for the late post!

One thing one needs to keep in mind about the storage is the as-if rule. The compiler is not required to put a variable in a specific place - instead it can place it wherever it pleases for as long as the compiled program behaves as if it were run in the abstract C machine according to the rules of the abstract C machine. This applies to all storage durations. For example:

• a variable that is not accessed all can be eliminated completely - it has no storage... anywhere. Example - see how there is 42 in the generated assembly code but no sign of 404.
• a variable with automatic storage duration that does not have its address taken need not be stored in memory at all. An example would be a loop variable.
• a variable that is const or effectively const need not be in memory. Example - the compiler can prove that foo is effectively const and inlines its use into the code. bar has external linkage and the compiler cannot prove that it would not be changed outside the current module, hence it is not inlined.
• an object allocated with malloc need not reside in memory allocated from heap! Example - notice how the code does not have a call to malloc and neither is the value 42 ever stored in memory, it is kept in a register!
• thus an object that has been allocated by malloc and the reference is lost without deallocating the object with free need not leak memory...
• the object allocated by malloc need not be within the heap below the program break (sbrk(0)) on Unixen...

As stated already, you can operate on Time objects as if they were numeric (or floating point) values. These operations result in second resolution which can easily be converted.

For example:

def time_diff_milli(start, finish)
   (finish - start) * 1000.0
end

t1 = Time.now
# arbitrary elapsed time
t2 = Time.now

msecs = time_diff_milli t1, t2

You will need to decide whether to truncate that or not.

I found many answers but not one is simple... I hope this will help you...

try{
    Intent intent = new Intent(CurrentActivity.this, NewActivity.class);
    startActivity(intent);
} finally {
    finish();
}

so, Very simple logic is here, as we know that in java we write code that has some chances of exception in a try block and handle that exception in catch block but in finally block we write code that has to be executed in any cost (Either the exception comes or not).

Your issue is with attempting to change your month by adding 1. 1 in date serials in Excel is equal to 1 day. Try changing your month by using the following:

NewDate = Format(DateAdd("m",1,StartDate),"dd/mm/yyyy")

Verry Easy, change order of element:

Origin

<div style="">

    My Text

    <button type="button" style="float: right; margin:5px;">
       My Button
    </button>

</div>

Change to:

<div style=""> 

    <button type="button" style="float: right; margin:5px;">
       My Button
     </button>

   My Text

</div>

The "evil" answer did not work for me. Instead, I used what was recommended on the JSHints docs page. If you know the warning that is thrown, you can turn it off for a block of code. For example, I am using some third party code that does not use camel case functions, yet my JSHint rules require it, which led to a warning. To silence it, I wrote:

/*jshint -W106 */
save_state(id);
/*jshint +W106 */

Late to the party, but the tsbox package is designed to perform conversions like this. To convert your data into a ts-object, you can do:

dta <- data.frame(
  Dates = c("3/14/2013", "3/15/2013", "3/18/2013", "3/19/2013"),
  Bajaj_close = c(1854.8, 1850.3, 1812.1, 1835.9),
  Hero_close = c(1669.1, 1684.45, 1690.5, 1645.6)
)

dta
#>       Dates Bajaj_close Hero_close
#> 1 3/14/2013      1854.8    1669.10
#> 2 3/15/2013      1850.3    1684.45
#> 3 3/18/2013      1812.1    1690.50
#> 4 3/19/2013      1835.9    1645.60

library(tsbox)
ts_ts(ts_long(dta))
#> Time Series:
#> Start = 2013.1971293045 
#> End = 2013.21081883954 
#> Frequency = 365.2425 
#>          Bajaj_close Hero_close
#> 2013.197      1854.8    1669.10
#> 2013.200      1850.3    1684.45
#> 2013.203          NA         NA
#> 2013.205          NA         NA
#> 2013.208      1812.1    1690.50
#> 2013.211      1835.9    1645.60

It automatically parses the dates, detects the frequency and makes the missing values at the weekends explicit. With ts_<class>, you can convert the data to any other time series class.

Posting a new answer since it is (almost) 2020.

The Android Emulator still only supports HAXM or WHPX on windows. And you may even call it a day already with the latter.

But if you don't like it, there is now work in progress AMD-V support for the former by one of the PS4 emulator developers: https://github.com/jarveson/haxm/tree/svm

First thing to do is run this:

SHOW GRANTS;

You will quickly see you were assigned the anonymous user to authenticate into mysql.

Instead of logging into mysql with

mysql

login like this:

mysql -uroot

By default, root@localhost has all rights and no password.

If you cannot login as root without a password, do the following:

Step 01) Add the two options in the mysqld section of my.ini:

[mysqld]
skip-grant-tables
skip-networking

Step 02) Restart mysql

net stop mysql
<wait 10 seconds>
net start mysql

Step 03) Connect to mysql

mysql

Step 04) Create a password from root@localhost

UPDATE mysql.user SET password=password('whateverpasswordyoulike')
WHERE user='root' AND host='localhost';
exit

Step 05) Restart mysql

net stop mysql
<wait 10 seconds>
net start mysql

Step 06) Login as root with password

mysql -u root -p

You should be good from there.

This is somewhat tricky since PHP gets evaluated server-side and javascript gets evaluated client side.

I would call your PHP file using an AJAX call from inside javascript and then use JS to insert the returned HTML somewhere on your page.

This probably isn't the most elegant way to do it, but it gets the job done.

In[1]: import numpy as np

In[2]: import pandas as pd

In[3]: df = pd.DataFrame(np.genfromtxt('/Users/spencerlyon2/Desktop/test.csv', dtype=str)[1:], columns=['ID'])

In[4]: df
Out[4]: 
                       ID
0  00013007854817840016671868
1  00013007854817840016749251

5  00013007854817840017963235
6  00013007854817840018860166

Just replace '/Users/spencerlyon2/Desktop/test.csv' with the path to your file

Off the top of my head, one way would be to grab all previous elements and count them.

$('td').click(function(){ 
    var colIndex = $(this).prevAll().length;
    var rowIndex = $(this).parent('tr').prevAll().length;
});

//Set the values
intent.putParcelableArrayListExtra("key",collection);

//Retrieve the values
ArrayList<OnlineMember> onlineMembers = data.getParcelableArrayListExtra("key");

I've had problems using /usr/bin/php on CPanel as it is compiled as a "cgi-fcgi" binary and not "cli". Try using /usr/local/bin/php or, as it is first in the path anyway, just use 'php' instead:

php /path/to/script.php

If you want to run the script as an executable, give it +x perms and use the following as the first line of the script:

#!/usr/bin/env php

I used below piece of code. Here dragAndDrop(x,y) is a method of Action class. Which takes two parameters (x,y), source location, and target location respectively

                System.out.println("Drag and Drom started :");
                Thread.sleep(12000);
                Actions actions = new Actions(webdriver);
                WebElement srcElement = webdriver.findElement(By.xpath("source Xpath"));
                WebElement targetElement = webdriver.findElement(By.xpath("Target Xpath"));
                actions.dragAndDrop(srcElement, targetElement); 
                actions.build().perform();
                System.out.println("Drag and Drom complated :");
            } catch (Exception e) {
                System.out.println(e.getMessage());
                resultDetails.setFlag(true);
            }

                    builder.setPositiveButton(getString(R.string.ok), new DialogInterface.OnClickListener() {

                case 500: {

                    if (grantResults.length == 0
                            || grantResults[0] !=
                            PackageManager.PERMISSION_GRANTED) {

                        Log.i("1", "Permission has been denied by user");

                    } else {

                        Log.i("1", "Permission has been granted by user");

                    }

                }

            }
        }

Best practise is to create an object (always use a . in ng-model)

In your controller:

var myObj: {
     ngModelValue: null
};

and in your template:

<select 
    ng-model="myObj.ngModelValue" 
    ng-options="o.id as o.name for o in options">
</select>

Now you can just watch

myObj.ngModelValue

or you can use the ng-change directive like so:

<select 
    ng-model="myObj.ngModelValue" 
    ng-options="o.id as o.name for o in options"
    ng-change="myChangeCallback()">
</select>

The egghead.io video "The Dot" has a really good overview, as does this very popular stack overflow question: What are the nuances of scope prototypal / prototypical inheritance in AngularJS?

This is the only install that resolved the issue for me.

If you are using a Form Control, you can get the same property as ActiveX by using OLEFormat.Object property of the Shape Object. Better yet assign it in a variable declared as OptionButton to get the Intellisense kick in.

Dim opt As OptionButton

With Sheets("Sheet1") ' Try to be always explicit
    Set opt = .Shapes("Option Button 1").OLEFormat.Object ' Form Control
    Debug.Pring opt.Value ' returns 1 (true) or -4146 (false)
End With

But then again, you really don't need to know the value.
If you use Form Control, you associate a Macro or sub routine with it which is executed when it is selected. So you just need to set up a sub routine that identifies which button is clicked and then execute a corresponding action for it.

For example you have 2 Form Control Option Buttons.

Sub CheckOptions()
    Select Case Application.Caller
    Case "Option Button 1"
    ' Action for option button 1
    Case "Option Button 2"
    ' Action for option button 2
    End Select
End Sub

In above code, you have only one sub routine assigned to both option buttons.
Then you test which called the sub routine by checking Application.Caller.
This way, no need to check whether the option button value is true or false.

further to what @JohnTESlade has answered. Google's python style guide has some pretty neat recommendations,

Names to Avoid

• single character names except for counters or iterators
• dashes (-) in any package/module name
• \__double_leading_and_trailing_underscore__ names (reserved by Python)

Naming Convention

• "Internal" means internal to a module or protected or private within a class.
• Prepending a single underscore (_) has some support for protecting module variables and functions (not included with import * from). Prepending a double underscore (__) to an instance variable or method effectively serves to make the variable or method private to its class (using name mangling).
• Place related classes and top-level functions together in a module. Unlike Java, there is no need to limit yourself to one class per module.
• Use CapWords for class names, but lower_with_under.py for module names. Although there are many existing modules named CapWords.py, this is now discouraged because it's confusing when the module happens to be named after a class. ("wait -- did I write import StringIO or from StringIO import StringIO?")

You can create a backup device in server object, let us say

BDTEST

and then create a batch file contain following command

sqlcmd -S 192.168.1.25 -E -Q "BACKUP DATABASE dbtest TO BDTEST"

let us say with name

backup.bat

then you can call

backup.bat

SELECT DateAdd(5,day(getdate()) this is for adding 5 days to current days. for eg:today date is 23/08/2018 it became 28/08/2018 by using the above query

if you're using SQL Server,

dateadd(DAY,0, datediff(day,0, created)) will return the day created

for example, if the sale created on '2009-11-02 06:12:55.000', dateadd(DAY,0, datediff(day,0, created)) return '2009-11-02 00:00:00.000'

select sum(amount) as total, dateadd(DAY,0, datediff(day,0, created)) as created
from sales
group by dateadd(DAY,0, datediff(day,0, created))

Figured it out. The VM's in cloud engine don't come with a root password setup by default so you'll first need to change the password using

sudo passwd

If you do everything correctly, it should do something like this:

user@server[~]# sudo passwd
Changing password for user root.
New password: 
Retype new password: 
passwd: all authentication tokens updated successfully.

In addition to the other answers here showing you how to git checkout <the-hash-you-want> it's worth knowing you can switch back to where you were using:

git checkout @{-1}

This is often more convenient than:

git checkout what-was-that-original-branch-called-again-question-mark

As you might anticipate, git checkout @{-2} will take you back to the branch you were at two git checkouts ago, and similarly for other numbers. If you can remember where you were for bigger numbers, you should get some kind of medal for that.

Sadly for productivity, git checkout @{1} does not take you to the branch you will be on in future, which is a shame.

You haven't put the shared library in a location where the loader can find it. look inside the /usr/local/opencv and /usr/local/opencv2 folders and see if either of them contains any shared libraries (files beginning in lib and usually ending in .so). when you find them, create a file called /etc/ld.so.conf.d/opencv.conf and write to it the paths to the folders where the libraries are stored, one per line.

for example, if the libraries were stored under /usr/local/opencv/libopencv_core.so.2.4 then I would write this to my opencv.conf file:

/usr/local/opencv/

Then run

sudo ldconfig -v

If you can't find the libraries, try running

sudo updatedb && locate libopencv_core.so.2.4

in a shell. You don't need to run updatedb if you've rebooted since compiling OpenCV.

format labels using lambda function

3x the same plot with differnt y-labeling

Minimal example

import numpy as np
import matplotlib as mpl
import matplotlib.pylab as plt
from matplotlib.ticker import FormatStrFormatter

fig, axs = mpl.pylab.subplots(1, 3)

xs = np.arange(10)
ys = 1 + xs ** 2 * 1e-3

axs[0].set_title('default y-labeling')
axs[0].scatter(xs, ys)
axs[1].set_title('custom y-labeling')
axs[1].scatter(xs, ys)
axs[2].set_title('x, pos arguments')
axs[2].scatter(xs, ys)


fmt = lambda x, pos: '1+ {:.0f}e-3'.format((x-1)*1e3, pos)
axs[1].yaxis.set_major_formatter(mpl.ticker.FuncFormatter(fmt))

fmt = lambda x, pos: 'x={:f}\npos={:f}'.format(x, pos)
axs[2].yaxis.set_major_formatter(mpl.ticker.FuncFormatter(fmt))

You can also use 'real'-functions instead of lambdas, of course. https://matplotlib.org/3.1.1/gallery/ticks_and_spines/tick-formatters.html

Here's a different approach. The heart of it was created by turning on the Macro Recorder and filtering the columns per your specifications. Then there's a bit of code to copy the results. It will run faster than looping through each row and column:

Sub FilterAndCopy()
Dim LastRow As Long

Sheets("Sheet2").UsedRange.Offset(0).ClearContents
With Worksheets("Sheet1")
    .Range("$A:$E").AutoFilter
    .Range("$A:$E").AutoFilter field:=1, Criteria1:="#N/A"
    .Range("$A:$E").AutoFilter field:=2, Criteria1:="=String1", Operator:=xlOr, Criteria2:="=string2"
    .Range("$A:$E").AutoFilter field:=3, Criteria1:=">0"
    .Range("$A:$E").AutoFilter field:=5, Criteria1:="Number"
    LastRow = .Range("A" & .Rows.Count).End(xlUp).Row
    .Range("A1:A" & LastRow).SpecialCells(xlCellTypeVisible).EntireRow.Copy _
            Destination:=Sheets("Sheet2").Range("A1")
End With
End Sub

As a side note, your code has more loops and counter variables than necessary. You wouldn't need to loop through the columns, just through the rows. You'd then check the various cells of interest in that row, much like you did.

In the popup window, overloads the method Show() with a parameter:

Then in the Main window, call your overloaded method Show():

Dim Popup As PopupWindow

Popup = New PopupWindow
Popup.Show(Me)

Another important difference is that Hashtable is thread safe. Hashtable has built in multiple reader/single writer (MR/SW) thread safety which means Hashtable allows ONE writer together with multiple readers without locking. In the case of Dictionary there is no thread safety, if you need thread safety you must implement your own synchronization.

To elaborate further:

Hashtable, provide some thread-safety through the Synchronized property, which returns a thread-safe wrapper around the collection. The wrapper works by locking the entire collection on every add or remove operation. Therefore, each thread that is attempting to access the collection must wait for its turn to take the one lock. This is not scalable and can cause significant performance degradation for large collections. Also, the design is not completely protected from race conditions.

The .NET Framework 2.0 collection classes like List<T>, Dictionary<TKey, TValue>, etc do not provide any thread synchronization; user code must provide all synchronization when items are added or removed on multiple threads concurrently If you need type safety as well thread safety, use concurrent collections classes in the .NET Framework. Further reading here.

It sounds like you're confused between pointers and arrays. Pointers and arrays (in this case char * and char []) are not the same thing.

• An array char a[SIZE] says that the value at the location of a is an array of length SIZE
• A pointer char *a; says that the value at the location of a is a pointer to a char. This can be combined with pointer arithmetic to behave like an array (eg, a[10] is 10 entries past wherever a points)

In memory, it looks like this (example taken from the FAQ):

 char a[] = "hello";  // array

   +---+---+---+---+---+---+
a: | h | e | l | l | o |\0 |
   +---+---+---+---+---+---+

 char *p = "world"; // pointer

   +-----+     +---+---+---+---+---+---+
p: |  *======> | w | o | r | l | d |\0 |
   +-----+     +---+---+---+---+---+---+

It's easy to be confused about the difference between pointers and arrays, because in many cases, an array reference "decays" to a pointer to it's first element. This means that in many cases (such as when passed to a function call) arrays become pointers. If you'd like to know more, this section of the C FAQ describes the differences in detail.

One major practical difference is that the compiler knows how long an array is. Using the examples above:

char a[] = "hello";  
char *p =  "world";  

sizeof(a); // 6 - one byte for each character in the string,
           // one for the '\0' terminator
sizeof(p); // whatever the size of the pointer is
           // probably 4 or 8 on most machines (depending on whether it's a 
           // 32 or 64 bit machine)

Without seeing your code, it's hard to recommend the best course of action, but I suspect changing to use pointers everywhere will solve the problems you're currently having. Take note that now:

• You will need to initialise memory wherever the arrays used to be. Eg, char a[10]; will become char *a = malloc(10 * sizeof(char));, followed by a check that a != NULL. Note that you don't actually need to say sizeof(char) in this case, because sizeof(char) is defined to be 1. I left it in for completeness.

• Anywhere you previously had sizeof(a) for array length will need to be replaced by the length of the memory you allocated (if you're using strings, you could use strlen(), which counts up to the '\0').

• You will need a make a corresponding call to free() for each call to malloc(). This tells the computer you are done using the memory you asked for with malloc(). If your pointer is a, just write free(a); at a point in the code where you know you no longer need whatever a points to.

As another answer pointed out, if you want to get the address of the start of an array, you can use:

char* p = &a[0] 

You can read this as "char pointer p becomes the address of element [0] of a".

Laravel 4.2 and beyond, may use try relationship querying:-

Products::whereHas('product_category', function($query) {
$query->whereIn('category_id', ['223', '15']);
});

public function product_category() {
return $this->hasMany('product_category', 'product_id');
}

Have a look at SortedList

This class implements a sorted list. It is constructed with a comparator that can compare two objects and sort objects accordingly. When you add an object to the list, it is inserted in the correct place. Object that are equal according to the comparator, will be in the list in the order that they were added to this list. Add only objects that the comparator can compare.

When the list already contains objects that are equal according to the comparator, the new object will be inserted immediately after these other objects.

You can use Oracle.ManagedDataAccess NuGet package too (.NET >= 4.0, database >= 10g Release 2).

A note to this:

IE 8.0s emulation only promises to display the page the same. There are subtle differences that might cause functionality to break. I recently had a problem with just that. Where IE 7.0 uses a javascript wrapper-function called "anonymous()" in IE 8.0 the wrapper was named differently.

So do not expect things like JavaScript to "just work", because you turn on emulation.

Try this out. After going through a lot of posts and forums, I found this.

You are plotting all your images on one axis. What you want ist to get a handle for each axis individually and plot your images there. Like so:

fig = plt.figure()
ax1 = fig.add_subplot(2,2,1)
ax1.imshow(...)
ax2 = fig.add_subplot(2,2,2)
ax2.imshow(...)
ax3 = fig.add_subplot(2,2,3)
ax3.imshow(...)
ax4 = fig.add_subplot(2,2,4)
ax4.imshow(...)

For complex layouts, you should consider using gridspec: http://matplotlib.org/users/gridspec.html

If you use nano with a language like python (as in your example) it's also a good idea to convert tabs to spaces.

Edit your ~/.nanorc file (or create it) and add:

set tabsize 4
set tabstospaces

If you already got a file with tabs and want to convert them to spaces i recommend the expandcommand (shell):

expand -4 input.py > output.py

1. Usually headers guards are for header files (i.e., .h ) not for source files ( i.e., .cpp ).
2. Include the necessary standard headers and namespaces in source files.

LinearNode.h:

#ifndef LINEARNODE_H
#define LINEARNODE_H

class LinearNode
{
    // .....
};

#endif

LinearNode.cpp:

#include "LinearNode.h"
#include <iostream>
using namespace std;
// And now the definitions

LinkedList.h:

#ifndef LINKEDLIST_H
#define LINKEDLIST_H

class LinearNode; // Forward Declaration
class LinkedList
{
    // ...
};

#endif

LinkedList.cpp

#include "LinearNode.h"
#include "LinkedList.h"
#include <iostream>
using namespace std;

// Definitions

test.cpp is source file is fine. Note that header files are never compiled. Assuming all the files are in a single folder -

g++ LinearNode.cpp LinkedList.cpp test.cpp -o exe.out

  Clinton        (CHECKED OUT, CURRENT WORKING DIRECTORY)              

In this very abbreviated history of the https://github.com/fleetwood-mac/band-history repository you have opened a pull request to merge in the the Bill Clinton commit into the original (MASTER) Fleetwood Mac commit.

You opened a pull request and on GitHub you see this:

Four commits:

• Add Danny Kirwan
• Add Christine Perfect
• LA1974
• Bill Clinton

Thinking that nobody would ever care to read the full repository history. (There actually is a repository, click the link above!) You decide to squash these commits. So you go and run git reset --soft HEAD~4 && git commit. Then you git push --force it onto GitHub to clean up your PR.

And what happens? You just made single commit that get from Fritz to Bill Clinton. Because you forgot that yesterday you were working on the Buckingham Nicks version of this project. And git log doesn't match what you see on GitHub.

MORAL OF THE STORY

1. Find the exact files you want to get to, and git checkout them
2. Find the exact prior commit you want to keep in history, and git reset --soft that
3. Make a git commit that warps directly from the from to the to

Right click on Git Bash shortcutand then go to properties.

Jianxun's solution did the job for me but broke the y value indicator at the bottom left of the window.

I ended up using FuncFormatterinstead (and also stripped the uneccessary trailing zeroes as suggested here):

import pandas as pd
import numpy as np
from matplotlib.ticker import FuncFormatter

df = pd.DataFrame(np.random.randn(100,5))

ax = df.plot()
ax.yaxis.set_major_formatter(FuncFormatter(lambda y, _: '{:.0%}'.format(y))) 

Generally speaking I'd recommend using FuncFormatter for label formatting: it's reliable, and versatile.

Choreographer lets apps to connect themselves to the vsync, and properly time things to improve performance.

Android view animations internally uses Choreographer for the same purpose: to properly time the animations and possibly improve performance.

Since Choreographer is told about every vsync events, it can tell if one of the Runnables passed along by the Choreographer.post* apis doesn't finish in one frame's time, causing frames to be skipped.

In my understanding Choreographer can only detect the frame skipping. It has no way of telling why this happens.

The message "The application may be doing too much work on its main thread." could be misleading.

There are many ways to do this in R. Specifically, by, aggregate, split, and plyr, cast, tapply, data.table, dplyr, and so forth.

Broadly speaking, these problems are of the form split-apply-combine. Hadley Wickham has written a beautiful article that will give you deeper insight into the whole category of problems, and it is well worth reading. His plyr package implements the strategy for general data structures, and dplyr is a newer implementation performance tuned for data frames. They allow for solving problems of the same form but of even greater complexity than this one. They are well worth learning as a general tool for solving data manipulation problems.

Performance is an issue on very large datasets, and for that it is hard to beat solutions based on data.table. If you only deal with medium-sized datasets or smaller, however, taking the time to learn data.table is likely not worth the effort. dplyr can also be fast, so it is a good choice if you want to speed things up, but don't quite need the scalability of data.table.

Many of the other solutions below do not require any additional packages. Some of them are even fairly fast on medium-large datasets. Their primary disadvantage is either one of metaphor or of flexibility. By metaphor I mean that it is a tool designed for something else being coerced to solve this particular type of problem in a 'clever' way. By flexibility I mean they lack the ability to solve as wide a range of similar problems or to easily produce tidy output.

Examples

base functions

tapply:

tapply(df$speed, df$dive, mean)
#     dive1     dive2 
# 0.5419921 0.5103974

aggregate:

aggregate takes in data.frames, outputs data.frames, and uses a formula interface.

aggregate( speed ~ dive, df, mean )
#    dive     speed
# 1 dive1 0.5790946
# 2 dive2 0.4864489

by:

In its most user-friendly form, it takes in vectors and applies a function to them. However, its output is not in a very manipulable form.:

res.by <- by(df$speed, df$dive, mean)
res.by
# df$dive: dive1
# [1] 0.5790946
# ---------------------------------------
# df$dive: dive2
# [1] 0.4864489

To get around this, for simple uses of by the as.data.frame method in the taRifx library works:

library(taRifx)
as.data.frame(res.by)
#    IDX1     value
# 1 dive1 0.6736807
# 2 dive2 0.4051447

split:

As the name suggests, it performs only the "split" part of the split-apply-combine strategy. To make the rest work, I'll write a small function that uses sapply for apply-combine. sapply automatically simplifies the result as much as possible. In our case, that means a vector rather than a data.frame, since we've got only 1 dimension of results.

splitmean <- function(df) {
  s <- split( df, df$dive)
  sapply( s, function(x) mean(x$speed) )
}
splitmean(df)
#     dive1     dive2 
# 0.5790946 0.4864489 

External packages

data.table:

library(data.table)
setDT(df)[ , .(mean_speed = mean(speed)), by = dive]
#    dive mean_speed
# 1: dive1  0.5419921
# 2: dive2  0.5103974

dplyr:

library(dplyr)
group_by(df, dive) %>% summarize(m = mean(speed))

plyr (the pre-cursor of dplyr)

Here's what the official page has to say about plyr:

It’s already possible to do this with base R functions (like split and the apply family of functions), but plyr makes it all a bit easier with:

• totally consistent names, arguments and outputs
• convenient parallelisation through the foreach package
• input from and output to data.frames, matrices and lists
• progress bars to keep track of long running operations
• built-in error recovery, and informative error messages
• labels that are maintained across all transformations

In other words, if you learn one tool for split-apply-combine manipulation it should be plyr.

library(plyr)
res.plyr <- ddply( df, .(dive), function(x) mean(x$speed) )
res.plyr
#    dive        V1
# 1 dive1 0.5790946
# 2 dive2 0.4864489

reshape2:

The reshape2 library is not designed with split-apply-combine as its primary focus. Instead, it uses a two-part melt/cast strategy to perform a wide variety of data reshaping tasks. However, since it allows an aggregation function it can be used for this problem. It would not be my first choice for split-apply-combine operations, but its reshaping capabilities are powerful and thus you should learn this package as well.

library(reshape2)
dcast( melt(df), variable ~ dive, mean)
# Using dive as id variables
#   variable     dive1     dive2
# 1    speed 0.5790946 0.4864489

Benchmarks

10 rows, 2 groups

library(microbenchmark)
m1 <- microbenchmark(

As usual, data.table has a little more overhead so comes in about average for small datasets. These are microseconds, though, so the differences are trivial. Any of the approaches works fine here, and you should choose based on:

• What you're already familiar with or want to be familiar with (plyr is always worth learning for its flexibility; data.table is worth learning if you plan to analyze huge datasets; by and aggregate and split are all base R functions and thus universally available)
• What output it returns (numeric, data.frame, or data.table -- the latter of which inherits from data.frame)

10 million rows, 10 groups

But what if we have a big dataset? Let's try 10^7 rows split over ten groups.

df <- data.frame(dive=factor(sample(letters[1:10],10^7,replace=TRUE)),speed=runif(10^7))
dt <- data.table(df)
setkey(dt,dive)

m2 <- microbenchmark(
  by( df$speed, df$dive, mean),
  aggregate( speed ~ dive, df, mean ),
  splitmean(df),
  ddply( df, .(dive), function(x) mean(x$speed) ),
  dcast( melt(df), variable ~ dive, mean),
  dt[,mean(speed),by=dive],
  times=2
)

                    by(df$speed, df$dive, mean)   720   770   799.1    791   816   958   100    d

autoplot(m2)

Then data.table or dplyr using operating on data.tables is clearly the way to go. Certain approaches (aggregate and dcast) are beginning to look very slow.

10 million rows, 1,000 groups

If you have more groups, the difference becomes more pronounced. With 1,000 groups and the same 10^7 rows:

df <- data.frame(dive=factor(sample(seq(1000),10^7,replace=TRUE)),speed=runif(10^7))
dt <- data.table(df)
setkey(dt,dive)

# then run the same microbenchmark as above

                    by(df$speed, df$dive, mean)   776   791   816.2    810   828   925   100  b    
              aggregate(speed ~ dive, df, mean) 11200 11400 11460.2  11400 11500 12000   100      f
                                  splitmean(df)  5940  6450  7562.4   7470  8370 11200   100     e

         dcast(melt(df), variable ~ dive, mean)  2110  2190  2267.8   2250  2290  2750   100    d

So data.table continues scaling well, and dplyr operating on a data.table also works well, with dplyr on data.frame close to an order of magnitude slower. The split/sapply strategy seems to scale poorly in the number of groups (meaning the split() is likely slow and the sapply is fast). by continues to be relatively efficient--at 5 seconds, it's definitely noticeable to the user but for a dataset this large still not unreasonable. Still, if you're routinely working with datasets of this size, data.table is clearly the way to go - 100% data.table for the best performance or dplyr with dplyr using data.table as a viable alternative.

methods: {
  debounceInput: _.debounce(function (e) {
    this.filterKey = e.target.value;

POCOs(Plain old CLR objects) are simply entities of your Domain. Normally when we use entity framework the entities are generated automatically for you. This is great but unfortunately these entities are interspersed with database access functionality which is clearly against the SOC (Separation of concern). POCOs are simple entities without any data access functionality but still gives the capabilities all EntityObject functionalities like

• Lazy loading
• Change tracking

Here is a good start for this

POCO Entity framework

You can also generate POCOs so easily from your existing Entity framework project using Code generators.

EF 5.X DbContext code generator

I had to replace new lines with br

string newString = oldString.Replace("\n", "<br />");

or if you use xml

<asp:Label ID="Label1" runat="server" Text='<%# ShowLineBreaks(Eval("Comments")) %>'></asp:Label>

Then in code behind

public string ShowLineBreaks(object text)
{
    return (text.ToString().Replace("\n", "<br/>"));
}

If you are using kotlin you can try the following code,

In the sending activity,

  val intent = Intent(context, RecorderService::class.java);
  intent.putExtra("filename", filename);
  context.startService(intent)

In the service,

override fun onStartCommand(intent: Intent, flags: Int, startId: Int): Int {
    super.onStartCommand(intent, flags, startId)

    if (intent != null && intent.extras != null)
       val filename = intent.getStringExtra("filename")

}

When you are using Multiple css property with jQuery then you must use the curly Brace in starting and in the end. You are missing the ending curly brace.

function init() {
 $("h1").css("backgroundColor", "yellow");

 $("#myParagraph").css({"background-color":"black","color":"white"});

 $(".bordered").css("border", "1px solid black");
}

You can have a look at this jQuery CSS Selector tutorial.

To count the number of diverse elements having a common type:

li = ['A0','c5','A8','A2','A5','c2','A3','A9']

print sum(1 for el in li if el[0]=='A' and el[1] in '01234')

gives

3 , not 6

Other posts here have made it clear that the result is an "empty" IQueryable, which ToList() will correctly change to be an empty list etc.

Do be careful with some of the operators, as they will throw if you send them an empty enumerable. This can happen when you chain them together.

you can try

isfar <- get(load('c:/users/isfar.Rdata'))

this will assign the variable in isfar.Rdata to isfar . After this assignment, you can use str(isfar) or ls(isfar) or head(isfar) to get a rough look of the isfar.

To add a column using a UDF:

df = sqlContext.createDataFrame(
    [(1, "a", 23.0), (3, "B", -23.0)], ("x1", "x2", "x3"))

from pyspark.sql.functions import udf
from pyspark.sql.types import *

def valueToCategory(value):
   if   value == 1: return 'cat1'
   elif value == 2: return 'cat2'
   ...
   else: return 'n/a'

# NOTE: it seems that calls to udf() must be after SparkContext() is called
udfValueToCategory = udf(valueToCategory, StringType())
df_with_cat = df.withColumn("category", udfValueToCategory("x1"))
df_with_cat.show()

## +---+---+-----+---------+
## | x1| x2|   x3| category|
## +---+---+-----+---------+
## |  1|  a| 23.0|     cat1|
## |  3|  B|-23.0|      n/a|
## +---+---+-----+---------+

You just need to put -y with the install command.

For example: yum install <package_to_install> -y

if things aren't lining up, a simple line-height: inherit; via CSS on specific i.fa elements that are having alignment issues could do the trick simply enough.

You could also feasibly use a global solution, which due to a slightly higher CSS specificity will override FontAwesome's .fa rule which specifies line-height: 1 without requiring !important on the property:

i.fa {
  line-height: inherit;
}

Just make sure that the above global solution doesn't cause any other issues in places where you might also use FontAwesome icons.

in 2020 you want immutable and universal functions

This walk through your multidimensional object composed of sub-objects, arrays and string and apply a custom function

export const iterate = (object, func) => {
  const entries = Object.entries(object).map(([key, value]) =>
    Array.isArray(value)
      ? [key, value.map(e => iterate(e, func))]
      : typeof value === 'object'
      ? [key, iterate(value, func)]
      : [key, func(value)]
  );
  return Object.fromEntries(entries);
};

usage:

const r = iterate(data, e=>'converted_'+e);
console.log(r);

Clear & Simple Instructions for Rails 5 & 6

• WARNING: You will lose data if you remove a column from your database. To proceed, see below:
• Warning: the below instructions are for trivial migrations. For complex migrations with e.g. millions and millions of rows, you will have to account for the possibility of failures, you will also have to think about how to optimise your migrations so that they run swiftly, and the possibility that users will use your app while the migration process is occurring. If you have multiple databases, or if anything is remotely complicated, then don't blame me if anything goes wrong!

1. Create a migration

Run the following command in your terminal:

rails generate migration remove_fieldname_from_tablename fieldname:fieldtype

Note: the table name should be in plural form as per rails convention.

Example:

In my case I want to remove the accepted column (a boolean value) from the quotes table:

rails g migration RemoveAcceptedFromQuotes accepted:boolean

See the documentation re: a convention when adding/removing fields to a table:

There is a special syntactic shortcut to generate migrations that add fields to a table.

rails generate migration add_fieldname_to_tablename fieldname:fieldtype

2. Check the migration

# db/migrate/20190122035000_remove_accepted_from_quotes.rb
class RemoveAcceptedFromQuotes < ActiveRecord::Migration[5.2]
  # with rails 5.2 you don't need to add a separate "up" and "down" method.
  def change
    remove_column :quotes, :accepted, :boolean
  end
end

3. Run the migration

rake db:migrate or rails db:migrate (they're both the same)

....And then you're off to the races!

In terminal go to which might be different in your PC :

C:\Program Files\Java\jre1.8.0_241\bin

Then:

For Windows:

keytool -list -v -keystore C:\Users\YOURUSERPROFILENAME\.android\debug.keystore -alias androiddebugkey -storepass android -keypass android

For Mac:

keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

For those who use ASP.NET Identity 2.1 and have changed the primary key from the default string to either int or Guid, if you're still getting

EntityType 'xxxxUserLogin' has no key defined. Define the key for this EntityType.

EntityType 'xxxxUserRole' has no key defined. Define the key for this EntityType.

you probably just forgot to specify the new key type on IdentityDbContext:

public class AppIdentityDbContext : IdentityDbContext<
    AppUser, AppRole, int, AppUserLogin, AppUserRole, AppUserClaim>
{
    public AppIdentityDbContext()
        : base("MY_CONNECTION_STRING")
    {
    }
    ......
}

If you just have

public class AppIdentityDbContext : IdentityDbContext
{
    ......
}

or even

public class AppIdentityDbContext : IdentityDbContext<AppUser>
{
    ......
}

you will get that 'no key defined' error when you are trying to add migrations or update the database.

I had the same issue. And I tried to reset my keys as everyone said, but it still didn't worked. For was because I renamed the app.

Date.parse recognizes only specific formats, and you don't have the option of telling it what your input format is. In this case it thinks that the input is in the format mm/dd/yyyy, so the result is wrong.

To fix this, you need either to parse the input yourself (e.g. with String.split) and then manually construct a Date object, or use a more full-featured library such as datejs.

Example for manual parsing:

var input = $('#' + controlName).val();
var parts = str.split("/");
var d1 = new Date(Number(parts[2]), Number(parts[1]) - 1, Number(parts[0]));

Example using date.js:

var input = $('#' + controlName).val();
var d1 = Date.parseExact(input, "d/M/yyyy");

you can use paste0 or cat method to combine string with variable values in R

For Example:

paste0("Value of A : ", a)

cat("Value of A : ", a)

You can't ref a property, but if your functions need both get and set access you can pass around an instance of a class with a property defined:

public class Property<T>
{
    public delegate T Get();
    public delegate void Set(T value);
    private Get get;
    private Set set;
    public T Value {
        get {
            return get();
        }
        set {
            set(value);
        }
    }
    public Property(Get get, Set set) {
        this.get = get;
        this.set = set;
    }
}

Example:

class Client
{
    private string workPhone; // this could still be a public property if desired
    public readonly Property<string> WorkPhone; // this could be created outside Client if using a regular public property
    public int AreaCode { get; set; }
    public Client() {
        WorkPhone = new Property<string>(
            delegate () { return workPhone; },
            delegate (string value) { workPhone = value; });
    }
}
class Usage
{
    public void PrependAreaCode(Property<string> phone, int areaCode) {
        phone.Value = areaCode.ToString() + "-" + phone.Value;
    }
    public void PrepareClientInfo(Client client) {
        PrependAreaCode(client.WorkPhone, client.AreaCode);
    }
}

What you're trying to accomplish is called Reverse DNS lookup.

Does '%' mean either "mod" or "rem" in C?

In C, % is the remainder¹.

..., the result of the / operator is the algebraic quotient with any fractional part discarded ... (This is often called "truncation toward zero".) C11dr §6.5.5 6

The operands of the % operator shall have integer type. C11dr §6.5.5 2

The result of the / operator is the quotient from the division of the first operand by the second; the result of the % operator is the remainder ... C11dr §6.5.5 5

What's the difference between “mod” and “remainder”?

C does not define "mod", such as the integer modulus function used in Euclidean division or other modulo. "Euclidean mod" differs from C's a%b operation when a is negative.

 // a % b
 7 %  3 -->  1  
 7 % -3 -->  1  
-7 %  3 --> -1  
-7 % -3 --> -1   

Modulo as Euclidean division

 7 modulo  3 -->  1  
 7 modulo -3 -->  1  
-7 modulo  3 -->  2  
-7 modulo -3 -->  2   

Candidate modulo code:

int modulo_Euclidean(int a, int b) {
  int m = a % b;
  if (m < 0) {
    // m += (b < 0) ? -b : b; // avoid this form: it is UB when b == INT_MIN
    m = (b < 0) ? m - b : m + b;
  }
  return m;
}

Note about floating point: double fmod(double x, double y), even though called "fmod", it is not the same as Euclidean division "mod", but similar to C integer remainder:

The fmod functions compute the floating-point remainder of x/y. C11dr §7.12.10.1 2

fmod( 7,  3) -->  1.0  
fmod( 7, -3) -->  1.0  
fmod(-7,  3) --> -1.0  
fmod(-7, -3) --> -1.0   

Disambiguation: C also has a similar named function double modf(double value, double *iptr) which breaks the argument value into integral and fractional parts, each of which has the same type and sign as the argument. This has little to do with the "mod" discussion here except name similarity.

[Edit Dec 2020]

For those who want proper functionality in all cases, an improved modulo_Euclidean() that 1) detects mod(x,0) and 2) a good and no UB result with modulo_Euclidean2(INT_MIN, -1). Inspired by 4 different implementations of modulo with fully defined behavior.

int modulo_Euclidean2(int a, int b) {
  if (b == 0) TBD_Code(); // perhaps return -1 to indicate failure?
  if (b == -1) return 0; // This test needed to prevent UB of `INT_MIN % -1`.
  int m = a % b;
  if (m < 0) {
    // m += (b < 0) ? -b : b; // avoid this form: it is UB when b == INT_MIN
    m = (b < 0) ? m - b : m + b;
  }
  return m;
}

¹ Prior to C99, C's definition of % was still the remainder from division, yet then / allowed negative quotients to round down rather than "truncation toward zero". See Why do you get different values for integer division in C89?. Thus with some pre-C99 compilation, % code can act just like the Euclidean division "mod". The above modulo_Euclidean() will work with this alternate old-school remainder too.

>>> import matplotlib.pyplot as plt
>>> a = [1,3,5,7]
>>> b = [11,-2,4,19]
>>> plt.pyplot.scatter(a,b)
>>> plt.scatter(a,b)
<matplotlib.collections.PathCollection object at 0x00000000057E2CF8>
>>> plt.show()
>>> c = [1,3,2,1]
>>> plt.errorbar(a,b,yerr=c, linestyle="None")
<Container object of 3 artists>
>>> plt.show()

where a is your x data b is your y data c is your y error if any

note that c is the error in each direction already

Use eval() instead of ast.literal_eval() if the input is trusted (which it is in your case).

raw_data = userfile.read().split('\n')
for a in raw_data : 
    print a
    btc_history.append(eval(a))

This works for me in Python 3.6.0

class SuperClass
{
    public void method1()
    {
        System.out.println("superclass method1");
        SuperClass se=new SuperClass();
        se.method2();
    }

    public void method2()
    {
        System.out.println("superclass method2");
    }
}


class SubClass extends SuperClass
{
    @Override
    public void method1()
    {
        System.out.println("subclass method1");
        super.method1();
    }

    @Override
    public void method2()
    {
        System.out.println("subclass method2");
    }
}

calling

SubClass mSubClass = new SubClass();
mSubClass.method1();

outputs

subclass method1
superclass method1
superclass method2

I also had the similar problem. I had a maven project and was testing rabbitmq. Firstly it showed me the similar error then I added all the SLF4J dependencies in the maven project and then error changed to "Maven SLF4J: Class path contains multiple SLF4J bindings". Here is the complete list of dependencies from pom.xlm

<dependencies>
    <dependency>
        <groupId>com.rabbitmq</groupId>
        <artifactId>amqp-client</artifactId>
        <version>4.0.0</version>
    </dependency>
    <dependency>
        <groupId>org.apache.commons</groupId>
        <artifactId>commons-lang3</artifactId>
        <version>3.0</version>
    </dependency>
    <dependency>
       <groupId>org.slf4j</groupId>
       <artifactId>slf4j-simple</artifactId>
       <version>1.7.21</version>
       <scope>compile</scope>
    </dependency>
</dependencies> 

It worked finally.

i think the problem lies within the space in the folder-name where your project is placed. /home/user/Dev/Java/Java%20Programs/SystemRoutines/target/classes/jsonschema.json

there is space between Java Programs.Renaming the folder name should make it work

Un updated answer: in knitr 1.17 you can simply use

![Image Title](path/to/your/image){width=250px}

edit as per comment from @jsb

Note this works only without spaces, e.g. {width=250px} not {width = 250px}

To support both Python 2 and Python 3, use explicit relative imports as below. They are relative to the current module. They have been supported starting from 2.5.

from .sister import foo
from . import brother
from ..aunt import bar
from .. import uncle

folder = "ABC" tries to run a command named folder with arguments = and "ABC". The format of command in bash is:

command arguments separated with space

while assignment is done with:

variable=something

• In [ -f $newfoldername/Primetime.eyetv], [ is a command (test) and -f and $newfoldername/Primetime.eyetv] are two arguments. It expects a third argument (]) which it can't find (arguments must be separated with space) and thus will show error.
• [-f $newfoldername/Primetime.eyetv] tries to run a command [-f with argument $newfoldername/Primetime.eyetv]

Generally for cases like this, paste your code in shellcheck and see the feedback.

if you are using Linux system, use sudo command

sudo npm i -g npx

I tried

res.status(400);
res.send('message');

..but it was giving me error:

(node:208) UnhandledPromiseRejectionWarning: Error: Can't set headers after they are sent.

This work for me

res.status(400).send(yourMessage);

$files = glob($_SERVER["DOCUMENT_ROOT"]."/myFolder/*");

I think better to used

$result->isEmpty();

The isEmpty method returns true if the collection is empty; otherwise, false is returned.
