Actually the @Ian Robinson answer works well but Chrome will continue complain with that message : "Resource interpreted as Font but transferred with MIME type application/x-woff"

If you get that, you can change from

application/x-woff

to

application/x-font-woff

and you will not have any Chrome console errors anymore !

(tested on Chrome 17)

In golang's wiki it show some tricks for slice, including delete an element from slice.

Link: enter link description here

For example a is the slice which you want to delete the number i element.

a = append(a[:i], a[i+1:]...)

OR

a = a[:i+copy(a[i:], a[i+1:])]

You could use GROUP_CONCAT aggregated function to get all years into a single column, grouped by id and ordered by rate:

SELECT   id, GROUP_CONCAT(year ORDER BY rate DESC) grouped_year
FROM     yourtable
GROUP BY id

Result:

-----------------------------------------------------------
|  ID | GROUPED_YEAR                                      |
-----------------------------------------------------------
| p01 | 2006,2003,2008,2001,2007,2009,2002,2004,2005,2000 |
| p02 | 2001,2004,2002,2003,2000,2006,2007                |
-----------------------------------------------------------

And then you could use FIND_IN_SET, that returns the position of the first argument inside the second one, eg.

SELECT FIND_IN_SET('2006', '2006,2003,2008,2001,2007,2009,2002,2004,2005,2000');
1

SELECT FIND_IN_SET('2009', '2006,2003,2008,2001,2007,2009,2002,2004,2005,2000');
6

Using a combination of GROUP_CONCAT and FIND_IN_SET, and filtering by the position returned by find_in_set, you could then use this query that returns only the first 5 years for every id:

SELECT
  yourtable.*
FROM
  yourtable INNER JOIN (
    SELECT
      id,
      GROUP_CONCAT(year ORDER BY rate DESC) grouped_year
    FROM
      yourtable
    GROUP BY id) group_max
  ON yourtable.id = group_max.id
     AND FIND_IN_SET(year, grouped_year) BETWEEN 1 AND 5
ORDER BY
  yourtable.id, yourtable.year DESC;

Please see fiddle here.

Please note that if more than one row can have the same rate, you should consider using GROUP_CONCAT(DISTINCT rate ORDER BY rate) on the rate column instead of the year column.

The maximum length of the string returned by GROUP_CONCAT is limited, so this works well if you need to select a few records for every group.

For increased performance you should not evaluate the dataframe using your predicate. You can just use the outcome of your predicate directly as illustrated below:

In [1]: import pandas as pd
        import numpy as np
        df = pd.DataFrame(np.random.randn(20,4),columns=list('ABCD'))


In [2]: df.head()
Out[2]:
          A         B         C         D
0 -2.019868  1.227246 -0.489257  0.149053
1  0.223285 -0.087784 -0.053048 -0.108584
2 -0.140556 -0.299735 -1.765956  0.517803
3 -0.589489  0.400487  0.107856  0.194890
4  1.309088 -0.596996 -0.623519  0.020400

In [3]: %time sum((df['A']>0) & (df['B']>0))
CPU times: user 1.11 ms, sys: 53 µs, total: 1.16 ms
Wall time: 1.12 ms
Out[3]: 4

In [4]: %time len(df[(df['A']>0) & (df['B']>0)])
CPU times: user 1.38 ms, sys: 78 µs, total: 1.46 ms
Wall time: 1.42 ms
Out[4]: 4

Keep in mind that this technique only works for counting the number of rows that comply with your predicate.

import java.util.*;
public class arrayList {
    public static void main(String[] args) {
        Scanner sc=new Scanner(System.in);
        ArrayList<String > x=new ArrayList<>();
        //inserting element
        x.add(sc.next());
        x.add(sc.next());
        x.add(sc.next());
        x.add(sc.next());
        x.add(sc.next());
         //to show element
         System.out.println(x);
        //converting arraylist to stringarray
         String[]a=x.toArray(new String[x.size()]);
          for(String s:a)
           System.out.print(s+" ");
  }

}

McGarnagle has a great answer, and you'll want to be accepting his, but I thought I'd mention (since you asked) how databinding works.

It's generally implemented by firing events whenever a change is made to the data, which then causes listeners (e.g. the UI) to be updated.

Two-way binding works by doing this twice, with a bit of care taken to ensure that you don't wind up stuck in an event loop (where the update from the event causes another event to be fired).

I was gonna put this in a comment, but it was getting pretty long...

in these cases you can try ssh if https is stuck.

Also you can try increasing the buffer size to an astronomical figure so that you dont have to worry about the buffer size any more git config http.postBuffer 100000000

if you want to delete rows based on some specific cell value. let suppose we have a file containing 10000 rows, and a fields having value of NULL. and based on that null value want to delete all those rows and records.

here are some simple tip. First open up Find Replace dialog, and on Replace tab, make all those cell containing NULL values with Blank. then press F5 and select the Blank option, now right click on the active sheet, and select delete, then option for Entire row.

it will delete all those rows based on cell value of containing word NULL.

Set the buttonTint property. For example, android:buttonTint="#99FF33".

Assertj is good at this.

import static org.assertj.core.api.Assertions.assertThat;

    assertThat(myClass.getMyItems()).extracting("name").contains("foo", "bar");

Big plus for assertj compared to hamcrest is easy use of code completion.

Something like this should work:

UPDATE
    table_Name
SET 
  column_A = CASE WHEN @flag = '1' THEN column_A + @new_value ELSE column_A END,
  column_B = CASE WHEN @flag = '0' THEN column_B + @new_value ELSE column_B END
WHERE
    ID = @ID

UPDATE -- use this instead:

<script type="text/babel" src="./lander.js"></script>

Add type="text/jsx" as an attribute of the script tag used to include the JavaScript file that must be transformed by JSX Transformer, like that:

<script type="text/jsx" src="./lander.js"></script>

Then you can use MAMP or some other service to host the page on localhost so that all of the inclusions work, as discussed here.

Thanks for all the help everyone!

This can be done using GroupBy and SelectMany in LINQ lamda expression

var groupByMax = list.GroupBy(x=>x.item1).SelectMany(y=>y.Where(z=>z.item2 == y.Max(i=>i.item2)));

The way I would do it is to create paragraph tags where you want your error messages with the same class and show them when the data is invalid. Here is my fiddle

if ($('#email').val() == '' || !$('#password').val() == '') {
    $('.loginError').show();
    return false;
}

I also added the paragraph tags below the email and password inputs

<p class="loginError" style="display:none;">please enter your email address or password.</p>

Yeah, no checkbox for you in iOS (-:

Here, this is what I did to create a checkbox:

UIButton *checkbox;
BOOL checkBoxSelected;
checkbox = [[UIButton alloc] initWithFrame:CGRectMake(x,y,20,20)];
// 20x20 is the size of the checkbox that you want
// create 2 images sizes 20x20 , one empty square and
// another of the same square with the checkmark in it
// Create 2 UIImages with these new images, then:

[checkbox setBackgroundImage:[UIImage imageNamed:@"notselectedcheckbox.png"]
                    forState:UIControlStateNormal];
[checkbox setBackgroundImage:[UIImage imageNamed:@"selectedcheckbox.png"]
                    forState:UIControlStateSelected];
[checkbox setBackgroundImage:[UIImage imageNamed:@"selectedcheckbox.png"]
                    forState:UIControlStateHighlighted];
checkbox.adjustsImageWhenHighlighted=YES;
[checkbox addTarget:(nullable id) action:(nonnull SEL) forControlEvents:(UIControlEvents)];
[self.view addSubview:checkbox];

Now in the target method do the following:

-(void)checkboxSelected:(id)sender
{
    checkBoxSelected = !checkBoxSelected; /* Toggle */
    [checkbox setSelected:checkBoxSelected];
}

That's it!

Try:

CREATE TABLE foo SELECT * FROM bar LIMIT 0

Or:

CREATE TABLE foo SELECT * FROM bar WHERE 1=0

getch() can also be used which is defined in conio.h.

The sample program would look like this :

#include <stdio.h>
#include <conio.h>

int main()
{
    //your code 
    getch();
    return 0; 
} 

getch() waits for any character input from the keyboard (not necessarily enter key).

Here is the syntax, along with some other methods you might find useful:

    //add to the end of the list
    stringList.add(random);

    //add to the beginning of the list
    stringList.add(0,  random);

    //replace the element at index 4 with random
    stringList.set(4, random);

    //remove the element at index 5
    stringList.remove(5);

    //remove all elements from the list
    stringList.clear();

yum install python-devel will work.

If yum doesn't work then use

apt-get install python-dev

package com.mycompany;

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

public class Car {

    @NotNull
    private String manufacturer;

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

    @Min(2)
    private int seatCount;

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

    //getters and setters ...
}

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

manufacturer shall never be null

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

seatCount shall be at least 2.

Select EventID,count() as cnt from dbo.EventInstances group by EventID having count() > 1

Even though you asked for wait() and notify() specifically, I feel that this quote is still important enough:

Josh Bloch, Effective Java 2nd Edition, Item 69: Prefer concurrency utilities to wait and notify (emphasis his):

Given the difficulty of using wait and notify correctly, you should use the higher-level concurrency utilities instead [...] using wait and notify directly is like programming in "concurrency assembly language", as compared to the higher-level language provided by java.util.concurrent. There is seldom, if ever, reason to use wait and notify in new code.

OutputDebugString function will do it.

example code

    void CClass::Output(const char* szFormat, ...)
{
    char szBuff[1024];
    va_list arg;
    va_start(arg, szFormat);
    _vsnprintf(szBuff, sizeof(szBuff), szFormat, arg);
    va_end(arg);

    OutputDebugString(szBuff);
}

See the Express docs as well as the Node docs for https.createServer (which is what express recommends to use):

var privateKey = fs.readFileSync( 'privatekey.pem' );
var certificate = fs.readFileSync( 'certificate.pem' );

https.createServer({
    key: privateKey,
    cert: certificate
}, app).listen(port);

Other options for createServer are at: http://nodejs.org/api/tls.html#tls_tls_createserver_options_secureconnectionlistener

If you want to be employed professionally as a game developer you need to know C/C++. End of story!

Suppose that you have a file Called "test.txt" with:

a=1.251
b=2.65415
c=3.54
d=549.5645
e=4684.65489

And you want to find a variable (a,b,c,d or e):

ffile=open('test.txt','r').read()

variable=raw_input('Wich is the variable you are looking for?\n')

ini=ffile.find(variable)+(len(variable)+1)
rest=ffile[ini:]
search_enter=rest.find('\n')
number=float(rest[:search_enter])

print "value:",number

Yes, add it to the php.ini, restart apache and it should work.

You can test it on the fly if you want to with ini_set("max_input_vars",100)

Instead use window.open():

The syntax is:

window.open(strUrl, strWindowName[, strWindowFeatures]);

Your code should have:

window.open('Prosjektplan.pdf');

Your code should be:

<p class="downloadBoks"
   onclick="window.open('Prosjektplan.pdf')">Prosjektbeskrivelse</p>

On my Windows 7 machine, it was solved by doing the following:

1. In the START menu type "regedit" to open the Registry (be careful doing this)
2. Go to "HKEY_LOCAL_MACHINE" on the left-hand side registry explorer/tree menu
3. Click "SOFTWARE" within the "HKEY_LOCAL_MACHINE" registries
4. Click "JavaSoft" within the "SOFTWARE" registries
5. Click "Java Runtime Environment" within the "JavaSoft" list of registries
6. Highlight "CurrentVersion" (should see it in the main registry key explorer window on the right)
7. Change version to "1.7"

That is all... should work. Short of that, if you've already tried some other guides and/or messed up your registries, the most certain way to deal with the problem is to delete all previous versions of Java (using "Programs and Features" uninstall process) and then re-install just the version you want to work with. I'd suggest the distribution site at: http://java.com (as it usually has the most stable version)

Or look for a specific version you need from Oracle's site: http://www.oracle.com/technetwork/java/javase/downloads/

Add a given line at the beginning of a file in two commands:

cat <(echo "blablabla") input_file.txt > tmp_file.txt
mv tmp_file.txt input_file.txt

Try this:

1. Uncomment the following line in /etc/default/docker DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4"
2. Restart the Docker service sudo service docker restart
3. Delete any images which have cached the invalid DNS settings.
4. Build again and the problem should be solved.

Adding to Mike McAllister's pretty-thorough answer...

Materialized views can only be set to refresh automatically through the database detecting changes when the view query is considered simple by the compiler. If it's considered too complex, it won't be able to set up what are essentially internal triggers to track changes in the source tables to only update the changed rows in the mview table.

When you create a materialized view, you'll find that Oracle creates both the mview and as a table with the same name, which can make things confusing.

A NULL pointer points to memory that doesn't exist. This may be address 0x00000000 or any other implementation-defined value (as long as it can never be a real address). Dereferencing it means trying to access whatever is pointed to by the pointer. The * operator is the dereferencing operator:

int a, b, c; // some integers
int *pi;     // a pointer to an integer

a = 5;
pi = &a; // pi points to a
b = *pi; // b is now 5
pi = NULL;
c = *pi; // this is a NULL pointer dereference

This is exactly the same thing as a NullReferenceException in C#, except that pointers in C can point to any data object, even elements inside an array.

There are lots of way we can do that and simply you can try following.

ls /home/user/new | tr '\n' '\n' | grep .txt

Another method:

cd /home/user/new && ls *.txt

event.key === "Enter"

More recent and much cleaner: use event.key. No more arbitrary number codes!

NOTE: The old properties (.keyCode and .which) are Deprecated.

const node = document.getElementsByClassName("mySelect")[0];
node.addEventListener("keydown", function(event) {
    if (event.key === "Enter") {
        event.preventDefault();
        // Do more work
    }
});

Modern style, with lambda and destructuring

node.addEventListener("keydown", ({key}) => {
    if (key === "Enter") // Handle press
})

System.Windows.Forms.DialogResult result = dlg.ShowDialog(this.GetIWin32Window());

Run the following immediately after the dialog is called in the Ajax:

    $(".ui-dialog-titlebar").hide();
    $(".ui-dialog").addClass("customclass");

This applies just to the dialog that is opened, so it can be changed for each one used.

(This quick answer is based on another response on Stack Overflow.)

You can receive returning results like that: AsyncTask class

@Override
protected Boolean doInBackground(Void... params) {
    if (host.isEmpty() || dbName.isEmpty() || user.isEmpty() || pass.isEmpty() || port.isEmpty()) {
        try {
            throw new SQLException("Database credentials missing");
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }

    try {
        Class.forName("org.postgresql.Driver");
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }

    try {
        this.conn = DriverManager.getConnection(this.host + ':' + this.port + '/' + this.dbName, this.user, this.pass);
    } catch (SQLException e) {
        e.printStackTrace();
    }

    return true;
}

receiving class:

_store.execute();
boolean result =_store.get();

Hoping it will help.

As mentioned, display:inline is probably what you want. Some browsers also support inline-blocks.

http://www.quirksmode.org/css/display.html#inlineblock

• Also Called Query Petition Clause.

• Similar to the Group By Clause

  • break up data into chunks (or partitions)
  • separate by partition bounds
  • function performs within partitions
  • re-initialised when crossing parting boundary

Syntax:
function (...) OVER (PARTITION BY col1 col3,...)

• Functions

  • Familiar functions such as COUNT(), SUM(), MIN(), MAX(), etc
  • New Functions as well (eg ROW_NUMBER(), RATION_TO_REOIRT(), etc.)

One of the most promising approaches seems to be opening a second communication channel back to the server to ask it how much of the transfer has been completed.

I had a scenario where nested JSON had to be serialised in a linear fashion while form data is constructed, since this is how server expects values. So, I wrote a small recursive function which translates the JSON which is like this:

{
   "orderPrice":"11",
   "cardNumber":"************1234",
   "id":"8796191359018",
   "accountHolderName":"Raj Pawan",
   "expiryMonth":"02",
   "expiryYear":"2019",
   "issueNumber":null,
   "billingAddress":{
      "city":"Wonderland",
      "code":"8796682911767",
      "firstname":"Raj Pawan",
      "lastname":"Gumdal",
      "line1":"Addr Line 1",
      "line2":null,
      "state":"US-AS",
      "region":{
         "isocode":"US-AS"
      },
      "zip":"76767-6776"
   }
}

Into something like this:

{
   "orderPrice":"11",
   "cardNumber":"************1234",
   "id":"8796191359018",
   "accountHolderName":"Raj Pawan",
   "expiryMonth":"02",
   "expiryYear":"2019",
   "issueNumber":null,
   "billingAddress.city":"Wonderland",
   "billingAddress.code":"8796682911767",
   "billingAddress.firstname":"Raj Pawan",
   "billingAddress.lastname":"Gumdal",
   "billingAddress.line1":"Addr Line 1",
   "billingAddress.line2":null,
   "billingAddress.state":"US-AS",
   "billingAddress.region.isocode":"US-AS",
   "billingAddress.zip":"76767-6776"
}

The server would accept form data which is in this converted format.

Here is the function:

function jsonToFormData (inJSON, inTestJSON, inFormData, parentKey) {
    // http://stackoverflow.com/a/22783314/260665
    // Raj: Converts any nested JSON to formData.
    var form_data = inFormData || new FormData();
    var testJSON = inTestJSON || {};
    for ( var key in inJSON ) {
        // 1. If it is a recursion, then key has to be constructed like "parent.child" where parent JSON contains a child JSON
        // 2. Perform append data only if the value for key is not a JSON, recurse otherwise!
        var constructedKey = key;
        if (parentKey) {
            constructedKey = parentKey + "." + key;
        }

        var value = inJSON[key];
        if (value && value.constructor === {}.constructor) {
            // This is a JSON, we now need to recurse!
            jsonToFormData (value, testJSON, form_data, constructedKey);
        } else {
            form_data.append(constructedKey, inJSON[key]);
            testJSON[constructedKey] = inJSON[key];
        }
    }
    return form_data;
}

Invocation:

        var testJSON = {};
        var form_data = jsonToFormData (jsonForPost, testJSON);

I am using testJSON just to see the converted results since I would not be able to extract the contents of form_data. AJAX post call:

        $.ajax({
            type: "POST",
            url: somePostURL,
            data: form_data,
            processData : false,
            contentType : false,
            success: function (data) {
            },
            error: function (e) {
            }
        });

There's a niche case where git mv remains very useful: when you want to change the casing of a file name on a case-insensitive file system. Both APFS (mac) and NTFS (windows) are, by default, case-insensitive (but case-preserving).

greg.kindel mentions this in a comment on CB Bailey's answer.

Suppose you are working on a mac and have a file Mytest.txt managed by git. You want to change the file name to MyTest.txt.

You could try:

$ mv Mytest.txt MyTest.txt
overwrite MyTest.txt? (y/n [n]) y
$ git status
On branch master
Your branch is up to date with 'origin/master'.

nothing to commit, working tree clean

Oh dear. Git doesn't acknowledge there's been any change to the file.

You could work around this with by renaming the file completely then renaming it back:

$ mv Mytest.txt temp.txt
$ git rm Mytest.txt
rm 'Mytest.txt'
$ mv temp.txt MyTest.txt
$ git add MyTest.txt 
$ git status
On branch master
Your branch is up to date with 'origin/master'.

Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

    renamed:    Mytest.txt -> MyTest.txt

Hurray!

Or you could save yourself all that bother by using git mv:

$ git mv Mytest.txt MyTest.txt
$ git status
On branch master
Your branch is up to date with 'origin/master'.

Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

    renamed:    Mytest.txt -> MyTest.txt

None of the tips in the best answer worked for me. Was going crazy. Then noticed that the Assistant Editor had somehow gotten set to Manual and I was on the ViewController.swift (Interface) instead of the ViewController.swift file.

Changed that and problem solved. A bit embarrassing but hey, we are all learning.

Use numpy.apply_along_axis(). Assuming your matrix is 2D, you can use like:

import numpy as np
mymatrix = np.matrix([[11,12,13],
                      [21,22,23],
                      [31,32,33]])
def myfunction( x ):
    return sum(x)

print np.apply_along_axis( myfunction, axis=1, arr=mymatrix )
#[36 66 96]

You're looking for itertools.compress:

>>> from itertools import compress
>>> list_a = [1, 2, 4, 6]
>>> fil = [True, False, True, False]
>>> list(compress(list_a, fil))
[1, 4]

Timing comparisons(py3.x):

>>> list_a = [1, 2, 4, 6]
>>> fil = [True, False, True, False]
>>> %timeit list(compress(list_a, fil))
100000 loops, best of 3: 2.58 us per loop
>>> %timeit [i for (i, v) in zip(list_a, fil) if v]  #winner
100000 loops, best of 3: 1.98 us per loop

>>> list_a = [1, 2, 4, 6]*100
>>> fil = [True, False, True, False]*100
>>> %timeit list(compress(list_a, fil))              #winner
10000 loops, best of 3: 24.3 us per loop
>>> %timeit [i for (i, v) in zip(list_a, fil) if v]
10000 loops, best of 3: 82 us per loop

>>> list_a = [1, 2, 4, 6]*10000
>>> fil = [True, False, True, False]*10000
>>> %timeit list(compress(list_a, fil))              #winner
1000 loops, best of 3: 1.66 ms per loop
>>> %timeit [i for (i, v) in zip(list_a, fil) if v] 
100 loops, best of 3: 7.65 ms per loop

_{Don't use filter as a variable name, it is a built-in function.}

Have you tried calling TcpClient.Dispose() explicitly?

And are you sure that you have TcpClient.Close() and TcpClient.Dispose()-ed ALL connections?

You are checking isset($_GET['event_id'] but you've not set that get variable in your hyperlink, you are just adding email

http://localhost/main.php?email=" . $email_address . $event_id

And add another GET variable in your link

$url = "http://localhost/main.php?email=$email_address&event_id=$event_id";

You did not use to concatenate your string if you are using " quotes

I did want to add one more answer that utilizes a VBA function, but it does get the job done in one SQL statement. Though, it can be slow.

UPDATE FUNCTIONS
SET FUNCTIONS.Func_TaxRef = DLookUp("MinOfTax_Code", "SELECT
FUNCTIONS.Func_ID,Min(TAX.Tax_Code) AS MinOfTax_Code

WHERE (((FUNCTIONS.Func_Pure)<=[Tax_ToPrice]) AND ((FUNCTIONS.Func_Year)=[Tax_Year]))
GROUP BY FUNCTIONS.Func_ID;", "FUNCTIONS.Func_ID=" & Func_ID)

You can try doing

<p>
  <a href="MY WEBSITE LINK" target="_blank">
    <img src="IMAGE LINK" style='width:100%;' border="0" alt="Null">
  </a>
</p>

This should scale your image if in a fluid layout.

For responsive (meaning your layout reacts to the size of the window) you can add a class to the image and use @media queries in CSS to change the width of the image.

Note that changing the height of the image will mess with the ratio.

Ok I have modified your code. This should do the job:

class Program
{
    static void Main(string[] args)
    {
        int[] array = { 10, 5, 10, 2, 2, 3, 4, 5, 5, 6, 7, 8, 9, 11, 12, 12 };

        for (int i = 0; i < array.Length; i++)
        {
            int count = 0;
            for (int j = 0; j < array.Length; j++)
            {

                if (array[i] == array[j])
                    count = count + 1;
            }
            Console.WriteLine("\t\n " + array[i] + " occurs " + count + " times");
        }
        Console.ReadKey();
    }
}

JavaScript only has a Number type that stores floating point values.

There is no int.

Edit:

If you want to format the number as a string with two digits after the decimal point use:

(4).toFixed(2)

Your problem..... I think is that your for loop is encompassing all of the if, else if stuff - which acts like one statement, like hoang nguyen pointed out.

Change to this. Note the brackets that denote the code block on which the for loop operates and the change of the first else if to if.

switch(value){

    case 1:
        for(int i=0; i<something_in_the_array.length;i++) {
            if(whatever_value==(something_in_the_array[i])) {
                value=2;
                break;
             }
        }

        if(whatever_value==2) {
            value=3;
            break;
        }
        else if(whatever_value==3) {
            value=4;
            break;
        }
        break;


    case 2:

code continues....

You need to set the parent element to 100% as well

html, body {
    height: 100%;
}

Demo (Changed the background for demo purpose)

Also, when you want to cover entire screen, seems like you want to dim, so in this case, you need to use position: fixed;

#dimScreen {
    width: 100%;
    height: 100%;
    background:rgba(255,255,255,0.5); 
    position: fixed;
    top: 0;
    left: 0;
    z-index: 100; /* Just to keep it at the very top */
}

If that's the case, than you don't need html, body {height: 100%;}

Demo 2

I have used the Open Clover Tool for the code coverage, I have also been searching this for a long time. Its pretty straightforward, in the Coverage Explorer tab, you can find three square buttons which says the code lines you wanted to display, click on hide the coverage square box and its gone. Last button in the image below:

You can use lscache. It handles this for you automatically, including instances where the storage size exceeds the limit. If that happens, it begins pruning items that are the closest to their specified expiration.

From the readme:

lscache.set

Stores the value in localStorage. Expires after specified number of minutes.

Arguments
key (string)
value (Object|string)
time (number: optional)

This is the only real difference between the regular storage methods. Get, remove, etc work the same.

If you don't need that much functionality, you can simply store a time stamp with the value (via JSON) and check it for expiry.

Noteworthy, there's a good reason why local storage is left up to the user. But, things like lscache do come in handy when you need to store extremely temporary data.

The other answers are all great/correct (the main difference is whether the DestTable exists already (INSERT), or doesn't exist yet (SELECT ... INTO))

You may prefer to use INSERT (instead of SELECT ... INTO), if you want to be able to COUNT(*) the rows that have been inserted so far.

Using SELECT COUNT(*) ... WITH NOLOCK is a simple/crude technique that may help you check the "progress" of the INSERT; helpful if it's a long-running insert, as seen in this answer).

[If you use...] INSERT DestTable SELECT ... FROM SrcTable ...then your SELECT COUNT(*) from DestTable WITH (NOLOCK) query would work.

shared folders VS synced folders

Basically shared folders are renamed to synced folder from v1 to v2 (docs), under the bonnet it is still using vboxsf between host and guest (there is known performance issues if there are large numbers of files/directories).

Vagrantfile directory mounted as /vagrant in guest

Vagrant is mounting the current working directory (where Vagrantfile resides) as /vagrant in the guest, this is the default behaviour.

See docs

NOTE: By default, Vagrant will share your project directory (the directory with the Vagrantfile) to /vagrant.

You can disable this behaviour by adding cfg.vm.synced_folder ".", "/vagrant", disabled: true in your Vagrantfile.

Why synced folder is not working

Based on the output /tmp on host was NOT mounted during up time.

Use VAGRANT_INFO=debug vagrant up or VAGRANT_INFO=debug vagrant reload to start the VM for more output regarding why the synced folder is not mounted. Could be a permission issue (mode bits of /tmp on host should be drwxrwxrwt).

I did a test quick test using the following and it worked (I used opscode bento raring vagrant base box)

config.vm.synced_folder "/tmp", "/tmp/src"

output

$ vagrant reload

You would use a Shape Drawable as the layout's background and set its cornerRadius. Check this blog for a detailed tutorial

Besides these given great answers, What I have learned is that:

NEVER compare objects with == unless you intend to be comparing them by their references.

In Java 8 for an Obj entity with field and getField() method you can use:

List<Obj> objs ...

Stream<Obj> notNullObjs =
  objs.stream().filter(obj -> obj.getValue() != null);

Double sum = notNullObjs.mapToDouble(Obj::getField).sum();

I had quite a number of these exceptions thrown, the fastest and easiest way I found to solve them was to find unique values in the exceptions which I then searched for in the storyboard source code. This helped me to find the actual view(s) and constraint(s) causing the problem (I use meaningful userLabels on all of the views, which makes it a lot easier to track the constraints and views)...

So, using the above exceptions I would open the storyboard as "source code" in xcode (or another editor) and look for something I can find...

<NSLayoutConstraint:0x72bf860 V:[UILabel:0x72bf7c0(17)]> 

.. this looks like a vertical (V) constraint on a UILabel with a value of (17).

Looking through the exceptions I also find

<NSLayoutConstraint:0x72c22b0 V:[UILabel:0x72bf7c0]-(NSSpace(8))-[UIButton:0x886efe0]>

Which looks like the UILabel(0x72bf7c0) is close to a UIButton(0x886efe0) with some vertical spacing (8)..

That will hopefully be enough for me to find the specific views in the storyboard source code (probably by searching the text for "17" initially), or at least a few likely candidates. From there I should be able to actually figure out which views these are in the storyboard which will make it a lot easier to identify the problem (look for "duplicated" pinning or pinning that conflicts with size constraints).

You can create a dynamic table rows as below:

var tbl = document.createElement('table');
tbl.style.width = '100%';

for (var i = 0; i < files.length; i++) {

        tr = document.createElement('tr');

        var td1 = document.createElement('td');
        var td2 = document.createElement('td');
        var td3 = document.createElement('td');

        ::::: // As many <td> you want

        td1.appendChild(document.createTextNode());
        td2.appendChild(document.createTextNode());
        td3.appendChild(document.createTextNode();

        tr.appendChild(td1);
        tr.appendChild(td2);
        tr.appendChild(td3);

        tbl.appendChild(tr);
}

If you're getting this error, you're probably trying to write to wwwroot. By default this is not allowed, for good reason.

Instead, consider storing your files somewhere besides wwwroot. If you just need to serve the files, store them in a folder outside of inetpub and use a virtual directory to make them visible to IIS.

Original answer:

For those running IIS on Windows Server:

By default, the IIS user does not have write permissions for the wwwroot folder. This can be solved by granting full permissions to the IIS_IUSRS user for wwwroot.

1. Open File Explorer and go to C:/inetpub/
2. Right click on wwwroot and click on "Properties"
3. Go to the Security tab and click "Edit..." to edit permissions
4. Find and select the IIS user. In my case, it was called IIS_IUSRS ([server name]\IIS_IUSRS).
5. Select the "Allow" checkbox for all permissions.

For Scalar Function Syntax is

Select dbo.Function_Name(parameter_name)

Select dbo.Department_Employee_Count('HR')

For saving the graph:

matplotlib.rcParams['savefig.dpi'] = 300

For displaying the graph when you use plt.show():

matplotlib.rcParams["figure.dpi"] = 100

Just add them at the top

A nice approach would be to start up your processes and services running them in the background and use the wait [n ...] command at the end of your script. In bash, the wait command forces the current process to:

Wait for each specified process and return its termination status. If n is not given, all currently active child processes are waited for, and the return status is zero.

I got this idea from Sébastien Pujadas' start script for his elk build.

Taking from the original question, your start-all.sh would look something like this...

 #!/usr/bin/env bash
 /etc/init.d/hadoop-hdfs-namenode start &
 /etc/init.d/hadoop-hdfs-datanode start &
 /etc/init.d/hadoop-hdfs-secondarynamenode start &
 /etc/init.d/hadoop-0.20-mapreduce-tasktracker start &
 sudo -u hdfs hadoop fs -chmod 777 /
 /etc/init.d/hadoop-0.20-mapreduce-jobtracker start &
 wait

I had a similar problem running SciPy on my computer. There are two ways to fix this problem: 1. Yes you do need to cd into your python directory. 2. Sometimes you have to tell the computer explicitly what path to go through, you have to find the program you're using, open up the properties, and reroute the path it takes to run. 3. consult the manual: http://matplotlib.org/users/installing.html or http://www.scipy.org/install.html

the Scipy package is very finicky, and needs things spelled out in obnoxious detail.

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

in task scheduler according to your convenience

you can use the Utility mettod. Arrays.deeptoString();

 public static void main(String[] args) {
    int twoD[][] = new int[4][]; 
    twoD[0] = new int[1]; 
    twoD[1] = new int[2]; 
    twoD[2] = new int[3]; 
    twoD[3] = new int[4]; 

    System.out.println(Arrays.deepToString(twoD));

}

I wonder, why nobody yet mentioned this possibility:

• If you provide ::listen(port) with string (intentionally or not), which wouldn't be a valid port number representation, it then can be internally converted to port number -1, ant then engine will try to connect to that -1 port, which then yields the same EADDRINUSE error, which in turn might be slightly confusing and turn you in the wrong direction for error fix search (hi, me xD).

So, debug your code and check what exactly you pass to functions, before starting to check for the processes, that are using your port.

That's the screenshot of the answer for your question.

1. Right click on the project and choose Open Module Settings.
2. Go to the Sources tab in your module.
3. Find your src folder.
4. Right click on it and mark it as Sources.

This solved the error in my case.

For linux users, you should know the following:

1. $CLASSPATH is specifically what Java uses to look through multiple directories to find all the different classes it needs for your script (unless you explicitly tell it otherwise with the -cp override). Using -cp (--classpath) requires that you keep track of all the directories manually and copy-paste that line every time you run the program (not preferable IMO).

2. The colon (":") character separates the different directories. There is only one $CLASSPATH and it has all the directories in it. So, when you run "export CLASSPATH=...." you want to include the current value "$CLASSPATH" in order to append to it. For example:

   export CLASSPATH=.
   export CLASSPATH=$CLASSPATH:/usr/share/java/mysql-connector-java-5.1.12.jar
   

   In the first line above, you start CLASSPATH out with just a simple 'dot' which is the path to your current working directory. With that, whenever you run java it will look in the current working directory (the one you're in) for classes. In the second line above, $CLASSPATH grabs the value that you previously entered (.) and appends the path to a mysql dirver. Now, java will look for the driver AND for your classes.

3. echo $CLASSPATH
   

   is super handy, and what it returns should read like a colon-separated list of all the directories you want java looking in for what it needs to run your script.

4. Tomcat does not use CLASSPATH. Read what to do about that here: https://tomcat.apache.org/tomcat-8.0-doc/class-loader-howto.html

You also have an error in your css with the exclamation point in this line:

background:rgb(242, 242, 242);!important;

remove the semi-colon before it. However, !important should be used rarely and can largely be avoided.

I can't answer the why part.

But if you want something dynamic then why don't you consider Collection ArrayList.

ArrrayList can be of any Object type.

And if as an compulsion you want it as an array you can use the toArray() method on it.

For example:

            ArrayList<String> al = new ArrayList<String>();
            al.add("one");
            al.add("two");
            String[] strArray = (String[]) al.toArray(new String[0]);

I hope this might help you.

I needed Signing hence couldn't un-check as suggested.

Then goto Control Panel -> Programs and Features -> Microsoft Visual Studio 2015 Click Change then the installer will load and you need to click Modify to add ClickOnce Publishing Tools feature.

I faced the same issue and I resolved it by using: max-width: fit-content;

All output:

scriptname &>/dev/null

Portable:

scriptname >/dev/null 2>&1

Portable:

scriptname >/dev/null 2>/dev/null

For newer bash (no portable):

scriptname &>-

echo basename(__DIR__); will return the current directory name only
echo basename(__FILE__); will return the current file name only

If you're using ReSharper, go into the ReSharper menu → Code → Generate...

(Or hit Alt + Ins inside the surrounding class), and you'll get all the options for generating getters and/or setters you can think of :-)

If you can't use jackson-modules-java8 for whatever reasons you can (de-)serialize the instant field as long using @JsonIgnore and @JsonGetter & @JsonSetter:

public class MyBean {

    private Instant time = Instant.now();

    @JsonIgnore
    public Instant getTime() {
        return this.time;
    }

    public void setTime(Instant time) {
        this.time = time;
    }

    @JsonGetter
    private long getEpochTime() {
        return this.time.toEpochMilli();
    }

    @JsonSetter
    private void setEpochTime(long time) {
        this.time = Instant.ofEpochMilli(time);
    }
}

Example:

@Test
public void testJsonTime() throws Exception {
    String json = new ObjectMapper().writeValueAsString(new MyBean());
    System.out.println(json);
    MyBean myBean = new ObjectMapper().readValue(json, MyBean.class);
    System.out.println(myBean.getTime());
}

yields

{"epochTime":1506432517242}

">" is the child selector

"" is the descendant selector

The difference is that a descendant can be a child of the element, or a child of a child of the element or a child of a child of a child ad inifinitum.

A child element is simply one that is directly contained within the parent element:

<foo> <!-- parent -->
  <bar> <!-- child of foo, descendant of foo -->
    <baz> <!-- descendant of foo -->
    </baz>
  </bar>
</foo>

for this example, foo * would match <bar> and <baz>, whereas foo > * would only match <bar>.

As for your second question:

Which one is more efficient and why?

I'm not actually going to answer this question as it's completely irrelevant to development. CSS rendering engines are so fast that there is almost never* a reason to optimize CSS selectors beyond making them as short as possible.

Instead of worrying about micro-optimizations, focus on writing selectors that make sense for the case at hand. I often use > selectors when styling nested lists, because it's important to distinguish which level of the list is being styled.

_{* if it genuinely is an issue in rendering the page, you've probably got too many elements on the page, or too much CSS. Then you'll have to run some tests to see what the actual issue is.}

If you are using Angular UI Bootstrap, you can use tooltip with html syntax: tooltip-html-unsafe

e.g. update to angular 1.2.10 & angular-ui-bootstrap 0.11: http://jsfiddle.net/aX2vR/1/

old one: http://jsfiddle.net/8LMwz/1/

The key is the sql query, which you will set up as a string:

$sqlquery = "SELECT field1, field2 FROM table WHERE NOT columnA = 'x' AND NOT columbB = 'y'";

Note that there are a lot of ways to specify NOT. Another one that works just as well is:

$sqlquery = "SELECT field1, field2 FROM table WHERE columnA != 'x' AND columbB != 'y'";

Here is a full example of how to use it:

$link = mysql_connect($dbHost,$dbUser,$dbPass) or die("Unable to connect to database");
mysql_select_db("$dbName") or die("Unable to select database $dbName");
$sqlquery = "SELECT field1, field2 FROM table WHERE NOT columnA = 'x' AND NOT columbB = 'y'";
$result=mysql_query($sqlquery);

while ($row = mysql_fetch_assoc($result) {
//do stuff
}

You can do whatever you would like within the above while loop. Access each field of the table as an element of the $row array which means that $row['field1'] will give you the value for field1 on the current row, and $row['field2'] will give you the value for field2.

Note that if the column(s) could have NULL values, those will not be found using either of the above syntaxes. You will need to add clauses to include NULL values:

$sqlquery = "SELECT field1, field2 FROM table WHERE (NOT columnA = 'x' OR columnA IS NULL) AND (NOT columbB = 'y' OR columnB IS NULL)";

A Kotlin extension + some padding around the drawable

fun TextView.addDrawable(drawable: Int) {
val imgDrawable = ContextCompat.getDrawable(context, drawable)
compoundDrawablePadding = 32
setCompoundDrawablesWithIntrinsicBounds(imgDrawable, null, null, null)
}

From official reference

Full-text indexes can be used only with MyISAM tables. (In MySQL 5.6 and up, they can also be used with InnoDB tables.) Full-text indexes can be created only for CHAR, VARCHAR, or TEXT columns.

https://dev.mysql.com/doc/refman/5.5/en/fulltext-search.html

InnoDB with MySQL 5.5 does not support Full-text indexes.

If you have to deal with NTLM proxy authentication a good alternative is to use a configure a local proxy using CNTLM.

The credentials and domain are configured in /etc/cntlm.conf.

Afterwards you can just use you own proxy that handles all the NTLM stuff.

DesiredCapabilities capabilities = DesiredCapabilities.chrome();

Proxy proxy = new Proxy();
proxy.setHttpProxy("localhost:3128");
capabilities.setCapability(CapabilityType.PROXY, proxy);

driver = new ChromeDriver(capabilities);

I used System.Data.Linq.SqlClient.SqlMethods.Like(row.Name, "test") in my query.

This performs a case-insensitive comparison.

With the new C++ standard (may need special flags to be enabled on your compiler) you can simply do:

std::vector<int> v { 34,23 };
// or
// std::vector<int> v = { 34,23 };

Or even:

std::vector<int> v(2);
v = { 34,23 };

On compilers that don't support this feature (initializer lists) yet you can emulate this with an array:

int vv[2] = { 12,43 };
std::vector<int> v(&vv[0], &vv[0]+2);

Or, for the case of assignment to an existing vector:

int vv[2] = { 12,43 };
v.assign(&vv[0], &vv[0]+2);

Like James Kanze suggested, it's more robust to have functions that give you the beginning and end of an array:

template <typename T, size_t N>
T* begin(T(&arr)[N]) { return &arr[0]; }
template <typename T, size_t N>
T* end(T(&arr)[N]) { return &arr[0]+N; }

And then you can do this without having to repeat the size all over:

int vv[] = { 12,43 };
std::vector<int> v(begin(vv), end(vv));

Just Simply Use

if (System.IO.Directory.Exists(path))
{
    ...
}

NSLocale* currentLocale = [NSLocale currentLocale];
[[NSDate date] descriptionWithLocale:currentLocale];  

or use

NSDateFormatter *dateFormatter=[[NSDateFormatter alloc] init]; 
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
// or @"yyyy-MM-dd hh:mm:ss a" if you prefer the time with AM/PM 
NSLog(@"%@",[dateFormatter stringFromDate:[NSDate date]]);

You can try using groovy. It runs on the JVM and it comes with great support for running external processes and extracting the output:

http://groovy.codehaus.org/Executing+External+Processes+From+Groovy

You can see in this code taken from the same link how groovy makes it easy to get the status of the process:

println "return code: ${ proc.exitValue()}"
println "stderr: ${proc.err.text}"
println "stdout: ${proc.in.text}" // *out* from the external program is *in* for groovy

You could use the INDIRECT function. This takes a string and converts it into a range

More info here

=INDIRECT("K"&A2)

But it's preferable to use INDEX as it is less volatile.

=INDEX(K:K,A2)

This returns a value or the reference to a value from within a table or range

More info here

Put either function into cell B2 and fill down.

you could also create a class which extends ArrayList:

public static class MyList extends ArrayList<Myclass> {}

and then use it like:

List<MyClass> list = objectMapper.readValue(json, MyList.class);

As defined on Wikipedia, this should do it.

euc.dist <- function(x1, x2) sqrt(sum((x1 - x2) ^ 2))

There's also the rdist function in the fields package that may be useful. See here.

EDIT: Changed ** operator to ^. Thanks, Gavin.

public IEnumerable<string> Appender(IEnumerable<string> strings)
{
  List<string> myList = new List<string>();
  foreach(string str in strings)
  {
      myList.Add(str + "roxxors");
  }
  return myList;
}

or

public IEnumerable<string> Appender(IEnumerable<string> strings)
{
  foreach(string str in strings)
  {
      yield return str + "roxxors";
  }
}

using the yield construct, or simply

var newCollection = strings.Select(str => str + "roxxors"); //(*)

or

var newCollection = from str in strings select str + "roxxors"; //(**)

where the two latter use LINQ and (**) is just syntactic sugar for (*).

I have slightly modified the accepted answer by handling value types. I came across this when trying to do the following and because GetProperties() is zero length for value types I was getting an empty dataset. I know this is not the use case for the OP but thought I'd post this change in case anyone else came across the same thing.

Enumerable.Range(1, 10).ToList().ToDataSet();

public static DataSet ToDataSet<T>(this IList<T> list)
{
    var elementType = typeof(T);
    var ds = new DataSet();
    var t = new DataTable();
    ds.Tables.Add(t);

    if (elementType.IsValueType)
    {
        var colType = Nullable.GetUnderlyingType(elementType) ?? elementType;
        t.Columns.Add(elementType.Name, colType);

    } else
    {
        //add a column to table for each public property on T
        foreach (var propInfo in elementType.GetProperties())
        {
            var colType = Nullable.GetUnderlyingType(propInfo.PropertyType) ?? propInfo.PropertyType;
            t.Columns.Add(propInfo.Name, colType);
        }
    }

    //go through each property on T and add each value to the table
    foreach (var item in list)
    {
        var row = t.NewRow();

        if (elementType.IsValueType)
        {
            row[elementType.Name] = item;
        }
        else
        {
            foreach (var propInfo in elementType.GetProperties())
            {
                row[propInfo.Name] = propInfo.GetValue(item, null) ?? DBNull.Value;
            }
        }
        t.Rows.Add(row);
    }

    return ds;
}

You must have a server-side script to handle your request, it can't be done using javascript.

To send raw data without URIencoding or escaping special characters to the php and save it as new txt file you can send ajax request using post method and FormData like:

JS:

var data = new FormData();
data.append("data" , "the_text_you_want_to_save");
var xhr = (window.XMLHttpRequest) ? new XMLHttpRequest() : new activeXObject("Microsoft.XMLHTTP");
xhr.open( 'post', '/path/to/php', true );
xhr.send(data);

PHP:

if(!empty($_POST['data'])){
$data = $_POST['data'];
$fname = mktime() . ".txt";//generates random name

$file = fopen("upload/" .$fname, 'w');//creates new file
fwrite($file, $data);
fclose($file);
}

Edit:

As Florian mentioned below, the XHR fallback is not required since FormData is not supported in older browsers (formdata browser compatibiltiy), so you can declare XHR variable as:

var xhr = new XMLHttpRequest();

Also please note that this works only for browsers that support FormData such as IE +10.

The easiest way would probably be to convert the array into a java.util.ArrayList. Once it is in an arraylist, you can easily leverage the contains method.

public static boolean bagOfWords(String str)
{
    String[] words = {"word1", "word2", "word3", "word4", "word5"};  
    return (Arrays.asList(words).contains(str));
}

It is worth mentioning that there is also: database scoped global temporary tables(currently supported only by Azure SQL Database).

Global temporary tables for SQL Server (initiated with ## table name) are stored in tempdb and shared among all users’ sessions across the whole SQL Server instance.

Azure SQL Database supports global temporary tables that are also stored in tempdb and scoped to the database level. This means that global temporary tables are shared for all users’ sessions within the same Azure SQL Database. User sessions from other databases cannot access global temporary tables.

-- Session A creates a global temp table ##test in Azure SQL Database testdb1
-- and adds 1 row
CREATE TABLE ##test ( a int, b int);
INSERT INTO ##test values (1,1);

-- Session B connects to Azure SQL Database testdb1 
-- and can access table ##test created by session A
SELECT * FROM ##test
---Results
1,1

-- Session C connects to another database in Azure SQL Database testdb2 
-- and wants to access ##test created in testdb1.
-- This select fails due to the database scope for the global temp tables 
SELECT * FROM ##test
---Results
Msg 208, Level 16, State 0, Line 1
Invalid object name '##test'

ALTER DATABASE SCOPED CONFIGURATION

GLOBAL_TEMPORARY_TABLE_AUTODROP = { ON | OFF }

APPLIES TO: Azure SQL Database (feature is in public preview)

Allows setting the auto-drop functionality for global temporary tables. The default is ON, which means that the global temporary tables are automatically dropped when not in use by any session. When set to OFF, global temporary tables need to be explicitly dropped using a DROP TABLE statement or will be automatically dropped on server restart.

With Azure SQL Database single databases and elastic pools, this option can be set in the individual user databases of the SQL Database server. In SQL Server and Azure SQL Database managed instance, this option is set in TempDB and the setting of the individual user databases has no effect.

You may want to use one of the implementing class of java.util.Set<E> Interface e.g. java.util.HashSet<String> collection class.

A collection that contains no duplicate elements. More formally, sets contain no pair of elements e1 and e2 such that e1.equals(e2), and at most one null element. As implied by its name, this interface models the mathematical set abstraction.

Code will be As below.

[textarea id:message 0x0 class:custom-class "Insert text here"]<!-- No Rows No columns -->

[textarea id:message x2 class:custom-class "Insert text here"]<!-- Only Rows -->

[textarea id:message 12x class:custom-class "Insert text here"]<!-- Only Columns -->

[textarea id:message 10x2 class:custom-class "Insert text here"]<!-- Both Rows and Columns -->

I have seen a bug that manifested as "Error installing artifact: File ../null/... does not exist" (that is, the file was not found because there was "null" in the path). The reason was that one environment variable was not visible to maven. It was:

JV_SRCROOT=$DIRECTORY

instead of

export JV_SRCROOT=$DIRECTORY

(in the latter case the variable is visible to child processes)

$ lsof -wni tcp:3000

# Kill the running process
$ kill -9 5946

$ rm tmp/server.pids

foreman start etc start the service

More general, for arbitrary sized bitmaps:

#define BITS 8
#define BIT_SET(  p, n) (p[(n)/BITS] |=  (0x80>>((n)%BITS)))
#define BIT_CLEAR(p, n) (p[(n)/BITS] &= ~(0x80>>((n)%BITS)))
#define BIT_ISSET(p, n) (p[(n)/BITS] &   (0x80>>((n)%BITS)))

Daniel Hilgarth's answer above leads to a System.NotSupported exception With Entity-Framework. With Entity-Framework, it has to be:

table1.GroupBy(x => x.Text).Select(x => x.FirstOrDefault());

You can convert a string to a file object using io.StringIO and then pass that to the csv module:

from io import StringIO
import csv

scsv = """text,with,Polish,non-Latin,letters
1,2,3,4,5,6
a,b,c,d,e,f
ges,zólty,waz,idzie,waska,drózka,
"""

f = StringIO(scsv)
reader = csv.reader(f, delimiter=',')
for row in reader:
    print('\t'.join(row))

simpler version with split() on newlines:

reader = csv.reader(scsv.split('\n'), delimiter=',')
for row in reader:
    print('\t'.join(row))

Or you can simply split() this string into lines using \n as separator, and then split() each line into values, but this way you must be aware of quoting, so using csv module is preferred.

On Python 2 you have to import StringIO as

from StringIO import StringIO

instead.

The size of your image is not sufficient to see in a naked eye. So please try to use atleast 50x50

These posts apparently are in the wrong order! This is #3 in a series of 3 posts. Sorry.

I've "taken a few MORE liberties" with Lie Ryan's code. The linked list admittedly was time-consuming to access individual elements due to search overhead, i.e. walking down the list until you find the right element. I have now cured this by maintaining an address vector containing subscripts 0 through whatever paired with memory addresses. This works because the address vector is allocated all-at-once, thus contiguous in memory. Since the linked-list is no longer required, I've ripped out its associated code and structure.

This approach is not quite as efficient as a plain-and-simple static array would be, but at least you don't have to "walk the list" searching for the proper item. You can now access the elements by using a subscript. To enable this, I have had to add code to handle cases where elements are removed and the "actual" subscripts wouldn't be reflected in the pointer vector's subscripts. This may or may not be important to users. For me, it IS important, so I've made re-numbering of subscripts optional. If renumbering is not used, program flow goes to a dummy "missing" element which returns an error code, which users can choose to ignore or to act on as required.

From here, I'd advise users to code the "elements" portion to fit their needs and make sure that it runs correctly. If your added elements are arrays, carefully code subroutines to access them, seeing as how there's extra array structure that wasn't needed with static arrays. Enjoy!

You can also use self::CONST instead of $this->CONST if you want to call a static variable or function of the current class.

Take a look at the Boost documentation as well, regarding how you are using the macro:

In reference to BOOST_VERSION, from http://www.boost.org/doc/libs/1_37_0/libs/config/doc/html/boost_config/boost_macro_reference.html#boost_config.boost_macro_reference.boost_helper_macros:

Describes the boost version number in XXYYZZ format such that: (BOOST_VERSION % 100) is the sub-minor version, ((BOOST_VERSION / 100) % 1000) is the minor version, and (BOOST_VERSION / 100000) is the major version.

HTTP COOKIES

Cookies are key/value pairs used by websites to store state information on the browser. Say you have a website (example.com), when the browser requests a webpage the website can send cookies to store information on the browser.

Browser request example:

GET /index.html HTTP/1.1
Host: www.example.com

Example answer from the server:

HTTP/1.1 200 OK
Content-type: text/html
Set-Cookie: foo=10
Set-Cookie: bar=20; Expires=Fri, 30 Sep 2011 11:48:00 GMT
... rest  of the response

Here two cookies foo=10 and bar=20 are stored on the browser. The second one will expire on 30 September. In each subsequent request the browser will send the cookies back to the server.

GET /spec.html HTTP/1.1
Host: www.example.com
Cookie: foo=10; bar=20
Accept: */*

SESSIONS: Server side cookies

Server side cookies are known as "sessions". The website in this case stores a single cookie on the browser containing a unique Session Identifier. Status information (foo=10 and bar=20 above) are stored on the server and the Session Identifier is used to match the request with the data stored on the server.

Examples of usage

You can use both sessions and cookies to store: authentication data, user preferences, the content of a chart in an e-commerce website, etc...

Pros and Cons

Below pros and cons of the solutions. These are the first that comes to my mind, there are surely others.

Cookie Pros:

• scalability: all the data is stored in the browser so each request can go through a load balancer to different webservers and you have all the information needed to fullfill the request;
• they can be accessed via javascript on the browser;
• not being on the server they will survive server restarts;
• RESTful: requests don't depend on server state

Cookie Cons:

• storage is limited to 80 KB (20 cookies, 4 KB each)
• secure cookies are not easy to implement: take a look at the paper A secure cookie protocol

Session Pros:

• generally easier to use, in PHP there's probably not much difference.
• unlimited storage

Session Cons:

• more difficult to scale
• on web server restarts you can lose all sessions or not depending on the implementation
• not RESTful

sleep doesn't work because the display can only be updated after your main thread returns to the system. NSTimer is the way to go. To do this, you need to implement methods which will be called by the timer to change the buttons. An example:

- (void)button_circleBusy:(id)sender {
    firstButton.enabled = NO;
    // 60 milliseconds is .06 seconds
    [NSTimer scheduledTimerWithTimeInterval:.06 target:self selector:@selector(goToSecondButton:) userInfo:nil repeats:NO];
}
- (void)goToSecondButton:(id)sender {
    firstButton.enabled = YES;
    secondButton.enabled = NO;
    [NSTimer scheduledTimerWithTimeInterval:.06 target:self selector:@selector(goToThirdButton:) userInfo:nil repeats:NO];
}
...

check your value which you want to store in integer column. I think this is greater then range of integer. if you want to store value greater then integer range. you should use bigint datatype

For Mac using native library:

import Quartz as q
q.NSEvent.mouseLocation()

#x and y individually
q.NSEvent.mouseLocation().x
q.NSEvent.mouseLocation().y

If the Quartz-wrapper is not installed:

python3 -m pip install -U pyobjc-framework-Quartz

(The question specify Windows, but a lot of Mac users come here because of the title)

I had this error and the other fixes didn't help me, but changing the CPU type the emulator used did get it working.

Create a new emulator and try using mips or arm for the cpu selection

A pixel is the smallest unit value to render something with, but you can trick thickness with optical illusions by modifying colors (the eye can only see up to a certain resolution too).

Here is a test to prove this point:

div { border-color: blue; border-style: solid; margin: 2px; }

div.b1 { border-width: 1px; }
div.b2 { border-width: 0.1em; }
div.b3 { border-width: 0.01em; }
div.b4 { border-width: 1px; border-color: rgb(160,160,255); }

<div class="b1">Some text</div>
<div class="b2">Some text</div>
<div class="b3">Some text</div>
<div class="b4">Some text</div>

Output

Which gives the illusion that the last DIV has a smaller border width, because the blue border blends more with the white background.

Edit: Alternate solution

Alpha values may also be used to simulate the same effect, without the need to calculate and manipulate RGB values.

.container {
  border-style: solid;
  border-width: 1px;
  
  margin-bottom: 10px;
}

.border-100 { border-color: rgba(0,0,255,1); }
.border-75 { border-color: rgba(0,0,255,0.75); }
.border-50 { border-color: rgba(0,0,255,0.5); }
.border-25 { border-color: rgba(0,0,255,0.25); }

<div class="container border-100">Container 1 (alpha = 1)</div>
<div class="container border-75">Container 2 (alpha = 0.75)</div>
<div class="container border-50">Container 3 (alpha = 0.5)</div>
<div class="container border-25">Container 4 (alpha = 0.25)</div>

Use "REPLACE" to remove special characters.

REPLACE(ColumnName ,' " ','')

Ex: -

--Query ---

DECLARE @STRING AS VARCHAR(100)
SET @STRING ='VI''RA""NJA "'

SELECT @STRING 
SELECT REPLACE(REPLACE(@STRING,'''',''),'"','') AS MY_NAME

--Result---

VI'RA""NJA"

Arduino sketches are written in C++.

Here is a typical construct you'll encounter:

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
...
lcd.begin(16, 2);
lcd.print("Hello, World!");

That's C++, not C.

Hence do yourself a favor and learn C++. There are plenty of books and online resources available.

The documentation for focusout says (emphasis mine):

The focusout event is sent to an element when it, or any element inside of it, loses focus. This is distinct from the blur event in that it supports detecting the loss of focus on descendant elements (in other words, it supports event bubbling).

The same distinction exists between the focusin and focus events.

You should include "bPaginate": false, into the configuration object you pass to your constructor parameters. As seen here: http://datatables.net/release-datatables/examples/basic_init/filter_only.html

That is exactly how you do it in C#, but the feature was first added in .NET 4.0

I am use to read full data:

// inputStream is one instance InputStream
byte[] data = new byte[inputStream.available()];
inputStream.read(data);
String dataString = new String(data);

to get this working for a date error I had to delete the error first before calling $setValidity for the form to be marked valid.

delete currentmodal.form.$error.date;
currentmodal.form.$setValidity('myDate', true);

Here is the solution.

The HTML:

<table cellspacing="0" cellpadding="0">
    <tr>
        <td>
            123
        </td>
    </tr>
</table>

The CSS:

table { 
      border-spacing:0; 
      border-collapse:collapse;   
    }

Hope this helps.

This is just Microsoft being cheeky. "Deprecated" implies a language feature that may not be provided in future versions of the standard language / standard libraries, as decreed by the standards committee. It does not, or should not mean, "we, unilaterally, don't think you should use it", no matter how well-founded that advice is.

try this command, xcopy c:\ (file or directory path) F:\ /e. If you want more details refer this site [[http://www.computerhope.com/xcopyhlp.htm]]

For VBScript use FormatDateTime, which has 5 numerical arguments to give you one of 5 predefined formats. Its not great.

  FormatDateTime(now, 4)
  08:12

You can use:

if (parentGuest.nextSibling) {
  parentGuest.parentNode.insertBefore(childGuest, parentGuest.nextSibling);
}
else {
  parentGuest.parentNode.appendChild(childGuest);
}

But as Pavel pointed out, the referenceElement can be null/undefined, and if so, insertBefore behaves just like appendChild. So the following is equivalent to the above:

parentGuest.parentNode.insertBefore(childGuest, parentGuest.nextSibling);

@Shane Arney

performSelector:withObject:withObject:

You might also want to mention that this method is only for passing maximum 2 arguments, and it cannot be delayed. (such as performSelector:withObject:afterDelay:).

kinda weird that apple only supports 2 objects to be send and didnt make it more generic.

You could just use the bound ng-model (answers[item.questID]) value itself in your ng-change method to detect if it has been checked or not.

Example:-

<input type="checkbox" ng-model="answers[item.questID]" 
     ng-change="stateChanged(item.questID)" /> <!-- Pass the specific id -->

and

$scope.stateChanged = function (qId) {
   if($scope.answers[qId]){ //If it is checked
       alert('test');
   }
}

For easy iterating over your nested dictionary, why not just write a simple generator?

def each_job(my_dict):
    for state, a in my_dict.items():
        for county, b in a.items():
            for job, value in b.items():
                yield {
                    'state'  : state,
                    'county' : county,
                    'job'    : job,
                    'value'  : value
                }

So then, if you have your compilicated nested dictionary, iterating over it becomes simple:

for r in each_job(my_dict):
    print "There are %d %s in %s, %s" % (r['value'], r['job'], r['county'], r['state'])

Obviously your generator can yield whatever format of data is useful to you.

Why are you using try catch blocks to read the tree? It's easy enough (and probably safer) to query whether a key exists in a dict before trying to retrieve it. A function using guard clauses might look like this:

if not my_dict.has_key('new jersey'):
    return False

nj_dict = my_dict['new jersey']
...

Or, a perhaps somewhat verbose method, is to use the get method:

value = my_dict.get('new jersey', {}).get('middlesex county', {}).get('salesmen', 0)

But for a somewhat more succinct way, you might want to look at using a collections.defaultdict, which is part of the standard library since python 2.5.

import collections

def state_struct(): return collections.defaultdict(county_struct)
def county_struct(): return collections.defaultdict(job_struct)
def job_struct(): return 0

my_dict = collections.defaultdict(state_struct)

print my_dict['new jersey']['middlesex county']['salesmen']

I'm making assumptions about the meaning of your data structure here, but it should be easy to adjust for what you actually want to do.

Generate debug APK without dev-server

If you really want to generate a debug APK (for testing purpose) that can run without the development server, Congrats! here I am to help you. :)
Everyone is saying that we need to run two commands react-native bundle ... and then gradlew assembleDebug but the generated APK still doesnot work without development server. After many research & try I figured out that we need to change in the gradle file (as in step-2). Just follow these steps:

1. In your react native project go to /android/app/src/main create a folder assets
2. edit android > app > build.gradle

project.ext.react = [
    ...
    bundleInDebug: true, // add this line
]

3. run this command at the root directory of your react native project

react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res

4. Now, go into the android folder: cd android
5. And, run this command: gradlew assembleDebug
   (if build failed, try building assembleDebug from android studio)

This will create app-debug.apk file in android/app/build/outputs/apk/debug directory, which you can install & run without dev-server.

With plt.scatter, I can only think of one: to use a proxy artist:

df = pd.DataFrame(np.random.normal(10,1,30).reshape(10,3), index = pd.date_range('2010-01-01', freq = 'M', periods = 10), columns = ('one', 'two', 'three'))
df['key1'] = (4,4,4,6,6,6,8,8,8,8)
fig1 = plt.figure(1)
ax1 = fig1.add_subplot(111)
x=ax1.scatter(df['one'], df['two'], marker = 'o', c = df['key1'], alpha = 0.8)

ccm=x.get_cmap()
circles=[Line2D(range(1), range(1), color='w', marker='o', markersize=10, markerfacecolor=item) for item in ccm((array([4,6,8])-4.0)/4)]
leg = plt.legend(circles, ['4','6','8'], loc = "center left", bbox_to_anchor = (1, 0.5), numpoints = 1)

And the result is:

Maybe you should allow to open links in new window when target is explicitly set to "_blank" as well :

$('a').live('click', function (event)
{      
    var href = $(this).attr("href");

    // prevent internal links (href.indexOf...) to open in safari if target
    // is not explicitly set_blank, doesn't break href="#" links
    if (href.indexOf(location.hostname) > -1 && href != "#" && $(this).attr("target") != "_blank")
    {
        event.preventDefault();
        window.location = href;
    }

});

Be aware that running

import os
os.system("tzutil /s \"Central Standard Time\"");

will alter Windows system time, NOT just the local python environment time (so is definitley NOT the same as:

>>> os.environ['TZ'] = 'Europe/London'
>>> time.tzset()

which will only set in the current environment time (in Unix only)

This is what you can do to source an .env (and .flaskenv) file in the pycharm flask/django console. It would also work for a normal python console of course.

1. Do pip install python-dotenv in your environment (the same as being pointed to by pycharm).

2. Go to: Settings > Build ,Execution, Deployment > Console > Flask/django Console

3. In "starting script" include something like this near the top:

   from dotenv import load_dotenv load_dotenv(verbose=True)

The .env file can look like this: export KEY=VALUE

It doesn't matter if one includes export or not for dotenv to read it.

As an alternative you could also source the .env file in the activate shell script for the respective virtual environement.

Java doesn't support true closures, even though using an anonymous class like you are using here (new TimerTask() { ... }) looks like a kind of closure.

edit - See the comments below - the following is not a correct explanation, as KeeperOfTheSoul points out.

This is why it doesn't work:

The variables lastPrice and price are local variables in the main() method. The object that you create with the anonymous class might last until after the main() method returns.

When the main() method returns, local variables (such as lastPrice and price) will be cleaned up from the stack, so they won't exist anymore after main() returns.

But the anonymous class object references these variables. Things would go horribly wrong if the anonymous class object tries to access the variables after they have been cleaned up.

By making lastPrice and price final, they are not really variables anymore, but constants. The compiler can then just replace the use of lastPrice and price in the anonymous class with the values of the constants (at compile time, of course), and you won't have the problem with accessing non-existent variables anymore.

Other programming languages that do support closures do it by treating those variables specially - by making sure they don't get destroyed when the method ends, so that the closure can still access the variables.

@Ankur: You could do this:

public static void main(String args[]) {
    int period = 2000;
    int delay = 2000;

    Timer timer = new Timer();

    timer.scheduleAtFixedRate(new TimerTask() {
        // Variables as member variables instead of local variables in main()
        private double lastPrice = 0;
        private Price priceObject = new Price();
        private double price = 0;

        public void run() {
            price = priceObject.getNextPrice(lastPrice);
            System.out.println();
            lastPrice = price;
        }
    }, delay, period);      
}

Your feature branch is done and ready to commit to master, develop or other target branch with only one commit

• Go to merge branch : git checkout master && git pull
• Create a work branch from your clean local master : git checkout -b work
• Merge squash your feature branch on work : git merge --squash your_feature_branch.
• Commit with default or a new message : git commit (with a specific or default message)
• Go back to your feature branch : git checkout your_feature_branch
• Point your feature branch to work dir : git reset --hard work
• Verify but you are ready to push : git push -f
• Then clean up work branch if needed

Replace master with your target branch : develop and so on

• No need to specify how many commit from your master to your feature branch. Git takes care*

You could use setUTCMilliseconds()

var _date = new Date();
_date.setUTCMilliseconds(1270544790922);

-XX:PermSize -XX:MaxPermSize are used to set size for Permanent Generation.

Permanent Generation: The Permanent Generation is where class files are kept. These are the result of compiled classes and JSP pages. If this space is full, it triggers a Full Garbage Collection. If the Full Garbage Collection cannot clean out old unreferenced classes and there is no room left to expand the Permanent Space, an Out-of- Memory error (OOME) is thrown and the JVM will crash.

Example 1 is for asp.net applications using forms authenication. This is common practice for internet applications because user is unauthenticated until it is authentcation against some security module.

Example 2 is for asp.net application using windows authenication. Windows Authentication uses Active Directory to authenticate users. The will prevent access to your application. I use this feature on intranet applications.

Use readlink:

readlink -f file.txt

A little bit hardcore but

this.router.onSameUrlNavigation = 'reload';
this.router.navigateByUrl(this.router.url).then(() => {

    this.router.onSameUrlNavigation = 'ignore';

});

String str = "cat";
char[] cArray = str.toCharArray();

Yes, you can use the cssfunction. The below will search all divs, but you can modify it for whatever elements you need

$('div').each(function(){

    if ( $(this).css('display') == 'none')
    {
       //do something
    }
});

For NSMutableArray, use the sortUsingSelector method. It sorts it-place, without creating a new instance.

The link I posted above is a great option that addresses the main issue: that we can never programmatically account for all cases (Smith-Jones, von Haussen, John Smith M.D.), at least not in an elegant manner. Tony introduces the concept of an exception / break character to deal with these cases. Anyways, building on Cervo's idea (upper all lower chars preceded by space), the replace statements could be wrapped up in a single table based replace instead. Really, any low/up character combination could be inserted into @alpha and the statement would not change:

declare @str    nvarchar(8000)
declare @alpha  table (low nchar(1), up nchar(1))


set @str = 'ALL UPPER CASE and    SOME lower ÄÄ ÖÖ ÜÜ ÉÉ ØØ CC ÆÆ'

-- stage the alpha (needs number table)
insert into @alpha
    -- A-Z / a-z
    select      nchar(n+32),
                nchar(n)
    from        dbo.Number
    where       n between 65 and 90 or
                n between 192 and 223

-- append space at start of str
set @str = lower(' ' + @str)

-- upper all lower case chars preceded by space
select  @str = replace(@str, ' ' + low, ' ' + up) 
from    @Alpha

select @str

None of above worked for me, because tint was cleared after click. I had to use

button.setImageTintColor(Palette.darkGray(), for: UIControlState())

If you need a button like this:

You can use RaisedButton and use the child property to do this. You need to add a Row and inside row you can add a Text widget and an Icon Widget to achieve this. If you want to use png image, you can use similar widget to achieve this.

RaisedButton(
    onPressed: () {},
    color: Theme.of(context).accentColor,
    child: Padding(
      padding: EdgeInsets.fromLTRB(
          SizeConfig.safeBlockHorizontal * 5,
          0,
          SizeConfig.safeBlockHorizontal * 5,
          0),
      child: Row(
        mainAxisAlignment: MainAxisAlignment.spaceBetween,
        children: <Widget>[
          Text(
            'Continue',
            style: TextStyle(
              fontSize: 20,
              fontWeight: FontWeight.w700,
              color: Colors.white,
            ),
          ),
          Icon(
            Icons.arrow_forward,
            color: Colors.white,
          )
        ],
      ),
    ),
  ),

Issue maybe occured because of the file/script created/downloaded from a windows machine. Please try converting into linux file format.

dos2unix ./script_name.sh

or

dos2unix ~/.bashrc

You can use this JavaScript\jQuery code:

// Sets active link in Bootstrap menu
// Add this code in a central place used\shared by all pages
// like your _Layout.cshtml in ASP.NET MVC for example
$('a[href="' + this.location.pathname + '"]').parents('li,ul').addClass('active');

It'll set the <a>'s parent <li> and the <li>'s parent <ul> as active.

A simple solution that works!

Original source:

Bootstrap add active class to li

Using Javascript, you can easily create a drop_bad.js script to drop your database:

create drop_bad.js:

use bad;
db.dropDatabase();

Than run 1 command in terminal to exectue the script using mongo shell:

mongo < drop_bad.js

I got a simple fix to this by casting the lists into strings and performing string operations to get the proper print out of the matrix.

Creating the function

By creating a function, it saves you the trouble of writing the for loop every time you want to print out a matrix.

def print_matrix(matrix):
    for row in matrix:
        new_row = str(row)
        new_row = new_row.replace(',','')
        new_row = new_row.replace('[','')
        new_row = new_row.replace(']','')
        print(new_row)

Examples

Example of a 5x5 matrix with 0 as every entry:

>>> test_matrix = [[0] * 5 for i in range(5)]
>>> print_matrix(test_matrix)
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0 

Example of a 2x3 matrix with 0 as every entry:

>>> test_matrix = [[0] * 3 for i in range(2)]
>>> print_matrix(test_matrix)
0 0 0
0 0 0

EDIT

If you want to make it print:

A A A A A
B B B B B
C C C C C
D D D D D 
E E E E E

I suggest you just change the way you enter your data into your lists within lists. In my method, each list within the larger list represents a line in the matrix, not columns.

set the dll path in the config file

<add key="dllPath" value="C:\Users\UserName\YourApp\myLibFolder\myDLL.dll" />

before calling the dll in you app, do the following

string dllPath= ConfigurationManager.AppSettings["dllPath"];    
   string appDirectory = Path.GetDirectoryName(dllPath);
   Directory.SetCurrentDirectory(appDirectory);

then call the dll and you can use like below

 [DllImport("myDLL.dll", CallingConvention = CallingConvention.Cdecl)]
public static extern int DLLFunction(int Number1, int Number2);

This is a very nice and clean example:(check this great tutorial for a full explanation link)

public static IEnumerable<SelectListItem> ToSelectListItems(
              this IEnumerable<Album> albums, int selectedId)
{
    return 
        albums.OrderBy(album => album.Name)
              .Select(album => 
                  new SelectListItem
                  {
                    Selected = (album.ID == selectedId),
                    Text = album.Name,
                    Value = album.ID.ToString()
                   });
}

In this MSDN link you can read de DropDownList method documentation.

Hope it helps.

Ctrl + End works for me on Visual C++ 2010 Express.

The most likely reason why the Java Runtime Environment JRE or Java Development Kit JDK is that it's owned by Oracle not Google and they would need a redistribution agreement which if you know there is some history between the two companies.

Lucky for us that Sun Microsystems before it was bought by Oracle open sourced Java and MySQL a win for us little guys.... Thank you Sun!

Google should probably have a caveat saying you may also need JRE OR JDK

Your "bad" output is UTF-8 displayed as CP1252.

On Windows, many editors assume the default ANSI encoding (CP1252 on US Windows) instead of UTF-8 if there is no byte order mark (BOM) character at the start of the file. While a BOM is meaningless to the UTF-8 encoding, its UTF-8-encoded presence serves as a signature for some programs. For example, Microsoft Office's Excel requires it even on non-Windows OSes. Try:

df.to_csv('file.csv',encoding='utf-8-sig')

That encoder will add the BOM.

Use LEFT combined with CHARINDEX:

UPDATE MyTable
SET MyText = LEFT(MyText, CHARINDEX(';', MyText) - 1)
WHERE CHARINDEX(';', MyText) > 0

Note that the WHERE clause skips updating rows in which there is no semicolon.

Here is some code to verify the SQL above works:

declare @MyTable table ([id] int primary key clustered, MyText varchar(100))
insert into @MyTable ([id], MyText)
select 1, 'some text; some more text'
union all select 2, 'text again; even more text'
union all select 3, 'text without a semicolon'
union all select 4, null -- test NULLs
union all select 5, '' -- test empty string
union all select 6, 'test 3 semicolons; second part; third part;'
union all select 7, ';' -- test semicolon by itself    

UPDATE @MyTable
SET MyText = LEFT(MyText, CHARINDEX(';', MyText) - 1)
WHERE CHARINDEX(';', MyText) > 0

select * from @MyTable

I get the following results:

id MyText
-- -------------------------
1  some text
2  text again
3  text without a semicolon
4  NULL
5        (empty string)
6  test 3 semicolons
7        (empty string)

Flatten the list to "remove the brackets" using a nested list comprehension. This will un-nest each list stored in your list of lists!

list_of_lists = [[180.0], [173.8], [164.2], [156.5], [147.2], [138.2]]
flattened = [val for sublist in list_of_lists for val in sublist]

Nested list comprehensions evaluate in the same manner that they unwrap (i.e. add newline and tab for each new loop. So in this case:

flattened = [val for sublist in list_of_lists for val in sublist]

is equivalent to:

flattened = []
for sublist in list_of_lists:
    for val in sublist:
        flattened.append(val)

The big difference is that the list comp evaluates MUCH faster than the unraveled loop and eliminates the append calls!

If you have multiple items in a sublist the list comp will even flatten that. ie

>>> list_of_lists = [[180.0, 1, 2, 3], [173.8], [164.2], [156.5], [147.2], [138.2]]
>>> flattened  = [val for sublist in list_of_lists for val in sublist]
>>> flattened 
[180.0, 1, 2, 3, 173.8, 164.2, 156.5, 147.2,138.2]

I picked node-sass implementer for libsass because it is based on node.js.

Installing node-sass

• (Prerequisite) If you don't have npm, install Node.js first.
• $ npm install -g node-sass installs node-sass globally -g.

This will hopefully install all you need, if not read libsass at the bottom.

How to use node-sass from Command line and npm scripts

General format:

$ node-sass [options] <input.scss> [output.css]
$ cat <input.scss> | node-sass > output.css

Examples:

1. $ node-sass my-styles.scss my-styles.css compiles a single file manually.
2. $ node-sass my-sass-folder/ -o my-css-folder/ compiles all the files in a folder manually.
3. $ node-sass -w sass/ -o css/ compiles all the files in a folder automatically whenever the source file(s) are modified. -w adds a watch for changes to the file(s).

More usefull options like 'compression' @ here. Command line is good for a quick solution, however, you can use task runners like Grunt.js or Gulp.js to automate the build process.

You can also add the above examples to npm scripts. To properly use npm scripts as an alternative to gulp read this comprehensive article @ css-tricks.com especially read about grouping tasks.

• If there is no package.json file in your project directory running $ npm init will create one. Use it with -y to skip the questions.
• Add "sass": "node-sass -w sass/ -o css/" to scripts in package.json file. It should look something like this:

"scripts": {
    "test" : "bla bla bla",
    "sass": "node-sass -w sass/ -o css/"
 }

• $ npm run sass will compile your files.

How to use with gulp

• $ npm install -g gulp installs Gulp globally.
• If there is no package.json file in your project directory running $ npm init will create one. Use it with -y to skip the questions.
• $ npm install --save-dev gulp installs Gulp locally. --save-dev adds gulp to devDependencies in package.json.
• $ npm install gulp-sass --save-dev installs gulp-sass locally.
• Setup gulp for your project by creating a gulpfile.js file in your project root folder with this content:

'use strict';
var gulp = require('gulp');

A basic example to transpile

Add this code to your gulpfile.js:

var gulp = require('gulp');
var sass = require('gulp-sass');
gulp.task('sass', function () {
  gulp.src('./sass/**/*.scss')
    .pipe(sass().on('error', sass.logError))
    .pipe(gulp.dest('./css'));
});

$ gulp sass runs the above task which compiles .scss file(s) in the sass folder and generates .css file(s) in the css folder.

To make life easier, let's add a watch so we don't have to compile it manually. Add this code to your gulpfile.js:

gulp.task('sass:watch', function () {
  gulp.watch('./sass/**/*.scss', ['sass']);
});

All is set now! Just run the watch task:

$ gulp sass:watch

How to use with Node.js

As the name of node-sass implies, you can write your own node.js scripts for transpiling. If you are curious, check out node-sass project page.

What about libsass?

Libsass is a library that needs to be built by an implementer such as sassC or in our case node-sass. Node-sass contains a built version of libsass which it uses by default. If the build file doesn't work on your machine, it tries to build libsass for your machine. This process requires Python 2.7.x (3.x doesn't work as of today). In addition:

LibSass requires GCC 4.6+ or Clang/LLVM. If your OS is older, this version may not compile. On Windows, you need MinGW with GCC 4.6+ or VS 2013 Update 4+. It is also possible to build LibSass with Clang/LLVM on Windows.

I'm posting this as an answer in case you are like me and cannot figure out why the range type input doesn't work on ANY mobile browsers. If you develop mobile apps on your laptop and use the responsive mode to emulate touch, you will notice the range doesn't even move when you have the touch simulator activated. It starts moving when you deactivate it. I went on for 2 days trying every piece of code I could find on the subject and could not make it work for the life of me. I provide a WORKING solution in this post.

Mobile Browsers And Hybrid Apps

Mobile browsers run using a component called Webkit for iOS and WebView for Android. The WebView/WebKit enables you to embed a web browser, which does not have any chrome or firefox (browser) controls including window frames, menus, toolbars and scroll bars into your activity layout. In other words, mobile browsers lack a lot of web components normally found in regular browsers. This is the problem with the range type input. If the user's browser doesn't support range type, it will fall back and treat it as a text input. This is why you cannot move the range when the touch simulator is activated.

Read more here on browser compatibility

jQuery Slider

jQuery provides a slider that somehow works with touch simulation but it is choppy and not very smooth. It wasn't satisfying to me and it probably wont be for you either but you can make it work more smoothly if you combine it with jqueryUi.

Best Solution : Range Touch

If you develop hybrid apps on your laptop, there is a simple and easy library you can use to enable range type input to work with touch events.

This library is called Range Touch.

Login to virtual machine use below command to check ip address. (anyone will work)

1. ifconfig
2. ip addr show

If you used NAT for your virtual machine settings(your machine ip will be 10.0.2.15), then you have to use port forwarding to connect to machine. IP address will be 127.0.0.1

If you used bridged networking/Host only networking, then you will have separate Ip address. Use that IP address to connect virtual machine

When you click on compose email in Gmail notice that the url changes from https://mail.google.com/mail/u/0/#inbox to https://mail.google.com/mail/u/0/#inbox?compose=new. Now when you enter say a email id [email protected] , the value for compose changes now the url became https://mail.google.com/mail/u/0/#inbox?compose=150b0f7ffb682642.

So this is working fine with my html hyperlink until the account is signed in, but if the account is not signed in it would take me the login page and when I enter the credentials somehow this compose value is lost and this does not work.

In the Oracle RDBMS, it is possible to use a multi-row subquery in the select clause as long as the (sub-)output is encapsulated as a collection. In particular, a multi-row select clause subquery can output each of its rows as an xmlelement that is encapsulated in an xmlforest.

You can also try copying the file to the SD Card folder, which is a public folder, then you can copy the file to your PC where you can use sqlite to access it.

Here is some code you can use to copy the file from data/data to a public storage folder:

private void copyFile(final Context context) {
    try {
        File sd = Environment.getExternalStorageDirectory();
        File data = Environment.getDataDirectory();

        if (sd.canWrite()) {
            String currentDBPath =
                    context.getDatabasePath(DATABASE_NAME).getAbsolutePath();

            String backupDBPath = "data.db";

            File currentDB = new File(currentDBPath);
            File backupDB = new File(sd, backupDBPath);

            if (currentDB.exists()) {
                FileChannel src = new FileInputStream(currentDB).getChannel();
                FileChannel dst = new FileOutputStream(backupDB).getChannel();
                dst.transferFrom(src, 0, src.size());
                src.close();
                dst.close();
            }
        }
    } catch (Exception e) {
        e.printStackTrace();
    }

I discovered today that we can now debug Javascript With the developer tool bar plugins integreted in IE 8.

• Click ? Tools on the toolbar, to the right of the tabs.
• Select Developer Tools. The Developer Tools dialogue should open.
• Click the Script tab in the dialogue.
• Click the Start Debugging button.

You can use watch, breakpoint, see the call stack etc, similarly to debuggers in professional browsers.

You can also use the statement debugger; in your JavaScript code the set a breakpoint.

You can do it like this

mylist = ['a', 'b', 'c', 'd', 'e']
myorder = [3, 2, 0, 1, 4]
mylist = [mylist[i] for i in myorder]
print(mylist)         # prints: ['d', 'c', 'a', 'b', 'e']

check this, its guaranteed and easy !

• add "readonly" attribute to the input field whenever you don't want the keyboard to show

 $("#inputField").attr("readonly","readonly");

• reset when clicking it

     $("#inputField").click(function () {
              $(this).removeAttr("readonly");
              $(this).focus();  
      });

Not CSS, but inline:

<a href="#" 
   onmouseover = "this.style.textDecoration = 'none'"
   onmouseout  = "this.style.textDecoration = 'underline'">Hello</a>

One angle not so far mentioned is tool sets used for editing the code.

Using Visual Studio Code along with the Extension from lukehoban called Go will do some auto-magic for you. The Go extension automatically runs gofmt, golint etc, and removes and adds import entries. So at least that part is now automatic.

I will admit its not 100% of the solution to the question, but however useful enough.

If you do run() in main method, the thread of main method will invoke the run method instead of the thread you require to run.

The start() method creates new thread and for which the run() method has to be done

WORD-WRAP

This property specifies whether the current rendered line should break if the content exceeds the boundary of the specified rendering box for an element (this is similar in some ways to the ‘clip’ and ‘overflow’ properties in intent.) This property should only apply if the element has a visual rendering, is an inline element with explicit height/width, is absolutely positioned and/or is a block element.

WORD-BREAK

This property controls the line breaking behavior within words. It is especially useful in cases where multiple languages are used within an element.

Here goes your code by parsing the variables in the function.

<html>
  <body>
    <p>Click the button to calculate x.</p>
    <button onclick="myFunction()">Try it</button>
    <br/>
    <br/>Enter first number:
    <input type="text" id="txt1" name="text1">
    <br>Enter second number:
    <input type="text" id="txt2" name="text2">
    <p id="demo"></p>

      function myFunction() {
        var y = parseInt(document.getElementById("txt1").value);
        var z = parseInt(document.getElementById("txt2").value);
        var x = y + z;
        document.getElementById("demo").innerHTML = x;

If there are up to 10 strings then you should use a list in order to iterate through all values.

{% set list1 = variable1.split(';') %}
{% for list in list1 %}
<p>{{ list }}</p>
{% endfor %}

1. To start the timer use console.time("myTimer");
2. Optional: To print the elapsed time, use console.timeLog("myTimer");
3. Finally, to stop the timer and print the final time: console.timeEnd("myTimer");

You can read more about this on MDN and in the Node.js documentation.

Available on Chrome, Firefox, Opera and NodeJS. (not on Edge or Internet Explorer).

Your static method should go from:

public static class SimpleUsing
{
    public static void DoUsing(Action<MyDataContext> action)
    {
        using (MyDataContext db = new MyDataContext())
           action(db);
    }
}

To:

public static class SimpleUsing
{
    public static TResult DoUsing<TResult>(Func<MyDataContext, TResult> action)
    {
        using (MyDataContext db = new MyDataContext())
           return action(db);
    }
}

This answer grew out of comments so I could provide code. For a complete elaboration, please see @sll's answer below.

Airdroid , android market install the app on android then go onto the computer type in the address given, type in the password given (or scan the QR code). Go to settings and under security (if your running the new ICS or Jellybean) or go to settings->apps->managment and select unknown sources(for gingerbread) then click on (I think) speed install, or something along those lines. it will be on the top of the page slightly towards the left. drag and drop as many .apks as you want then on you android just tap the install buttons that appear. Airdroid is wonderful and does a lot more than just apks.

If you give a Scanner object a String, it will read it in as data. That is, "a.txt" does not open up a file called "a.txt". It literally reads in the characters 'a', '.', 't' and so forth.

This is according to Core Java Volume I, section 3.7.3.

If I find a solution to reading the actual paths, I will return and update this answer. The solution this text offers is to use

Scanner in = new Scanner(Paths.get("myfile.txt"));

But I can't get this to work because Path isn't recognized as a variable by the compiler. Perhaps I'm missing an import statement.
