for current year we can use getFullYear() from Date class however there are many function which you can use as per the requirements, some functions are as,

var now = new Date()_x000D_
console.log("Current Time is: " + now);_x000D_
_x000D_
// getFullYear function will give current year _x000D_
var currentYear = now.getFullYear()_x000D_
console.log("Current year is: " + currentYear);_x000D_
_x000D_
// getYear will give you the years after 1990 i.e currentYear-1990_x000D_
var year = now.getYear()_x000D_
console.log("Current year is: " + year);_x000D_
_x000D_
// getMonth gives the month value but months starts from 0_x000D_
// add 1 to get actual month value _x000D_
var month = now.getMonth() + 1_x000D_
console.log("Current month is: " + month);_x000D_
_x000D_
// getDate gives the date value_x000D_
var day = now.getDate()_x000D_
console.log("Today's day is: " + day);

This worked for me in a small test:

sourceEncoding = "iso-8859-1"
targetEncoding = "utf-8"
source = open("source")
target = open("target", "w")

target.write(unicode(source.read(), sourceEncoding).encode(targetEncoding))

So after research the following is discovered:

For a div#bar setting display:block; width: auto; causes the equivalent of outerWidth:100%;

For a table#bar you need to wrap it in a div with the rules stated below. So your structure becomes:

<div id="foo">
 <div id="barWrap" style="border....">
  <table id="bar" style="width: 100%; border: 0; padding: 0; margin: 0;">

This way the table takes up the parent div 100%, and #barWrap is used to add borders/margin/padding to the #bar table. Note that you will need to set the background of the whole thing in #barWrap and have #bar's background be transparent or the same as #barWrap.

For textarea#bar and input#bar you need to do the same thing as table#bar, the down side is that by removing the borders you stop native widget rendering of the input/textarea and the #barWrap's borders will look a bit different than everything else, so you will probably have to style all your inputs this way.

Worked for me:

      var first = regexLabelOut.replace(/,.*/g, "");

I have started Activity A->B->C->D. When the back button is pressed on Activity D I want to go to Activity A. Since A is my starting point and therefore already on the stack all the activities in top of A is cleared and you can't go back to any other Activity from A.

This actually works in my code:

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_BACK) {
        Intent a = new Intent(this,A.class);
        a.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        startActivity(a);
        return true;
    }
    return super.onKeyDown(keyCode, event);
}       

A much more robust way would be to use the getline() function of GNU awk to use a variable from a pipe. In form cmd | getline result, cmd is run, then its output is piped to getline. It returns 1 if got output, 0 if EOF, -1 on failure.

First construct the command to run in a variable in the BEGIN clause if the command is not dependant on the contents of the file, e.g. a simple date or an ls.

A simple example of the above would be

awk 'BEGIN {
    cmd = "ls -lrth"
    while ( ( cmd | getline result ) > 0 ) {
        print result
    }
    close(cmd);
}'

When the command to run is part of the columnar content of a file, you generate the cmd string in the main {..} as below. E.g. consider a file whose $2 contains the name of the file and you want it to be replaced with the md5sum hash content of the file. You can do

awk '{ cmd = "md5sum "$2
       while ( ( cmd | getline md5result ) > 0 ) { 
           $2 = md5result
       }
       close(cmd);
 }1'

Another frequent usage involving external commands in awk is during date processing when your awk does not support time functions out of the box with mktime(), strftime() functions.

Consider a case when you have Unix EPOCH timestamp stored in a column and you want to convert that to a human readable date format. Assuming GNU date is available

awk '{ cmd = "date -d @" $1 " +\"%d-%m-%Y %H:%M:%S\"" 
       while ( ( cmd | getline fmtDate) > 0 ) { 
           $1 = fmtDate
       }
       close(cmd);
}1' 

for an input string as

1572608319 foo bar zoo

the above command produces an output as

01-11-2019 07:38:39 foo bar zoo

The command can be tailored to modify the date fields on any of the columns in a given line. Note that -d is a GNU specific extension, the *BSD variants support -f ( though not exactly similar to -d).

More information about getline can be referred to from this AllAboutGetline article at awk.freeshell.org page.

The right way is:

db.users.find({awards: {$elemMatch: {award:'National Medal', year:1975}}})

$elemMatch allows you to match more than one component within the same array element.

Without $elemMatch mongo will look for users with National Medal in some year and some award in 1975s, but not for users with National Medal in 1975.

See MongoDB $elemMatch Documentation for more info. See Read Operations Documentation for more information about querying documents with arrays.

I have just used dompdf and the code was a little different but it worked.

Here it is:

require_once("./pdf/dompdf_config.inc.php");
$files = glob("./pdf/include/*.php");
foreach($files as $file) include_once($file);

$html =
      '<html><body>'.
      '<p>Put your html here, or generate it with your favourite '.
      'templating system.</p>'.
      '</body></html>';

    $dompdf = new DOMPDF();
    $dompdf->load_html($html);
    $dompdf->render();
    $output = $dompdf->output();
    file_put_contents('Brochure.pdf', $output);

Only difference here is that all of the files in the include directory are included.

Other than that my only suggestion would be to specify a full directory path for writing the file rather than just the filename.

To multiply, use mult for signed multiplication and multu for unsigned multiplication. Note that the result of the multiplication of two 32-bit numbers yields a 64-number. If you want the result back in $v0 that means that you assume the result will fit in 32 bits.

The 32 most significant bits will be held in the HI special register (accessible by mfhi instruction) and the 32 least significant bits will be held in the LO special register (accessible by the mflo instruction):

E.g.:

li $a0, 5
li $a1, 3
mult $a0, $a1
mfhi $a2 # 32 most significant bits of multiplication to $a2
mflo $v0 # 32 least significant bits of multiplication to $v0

To divide, use div for signed division and divu for unsigned division. In this case, the HI special register will hold the remainder and the LO special register will hold the quotient of the division.

E.g.:

div $a0, $a1
mfhi $a2 # remainder to $a2
mflo $v0 # quotient to $v0

It looks like overriding the Target class or one of the implementations like BitmapImageViewTarget and overriding the setResource method to capture the bitmap might be the way to go...

This is untested. :-)

    Glide.with(context)
         .load("http://goo.gl/h8qOq7")
         .asBitmap()
         .into(new BitmapImageViewTarget(imageView) {
                     @Override
                     protected void setResource(Bitmap resource) {
                         // Do bitmap magic here
                         super.setResource(resource);
                     }
         });

Chapter 4.8 Block Structure in K&R's The C Programming Language 2.Ed.:

An automatic variable declared and initialized in a block is initialized each time the block is entered.

I might have missed seeing the relevant description in the book like:

An automatic variable declared and initialized in a block is allocated only one time before the block is entered.

But a simple test can prove the assumption held:

 #include <stdio.h>                                                                                                    

 int main(int argc, char *argv[]) {                                                                                    
     for (int i = 0; i < 2; i++) {                                                                                     
         for (int j = 0; j < 2; j++) {                                                                                 
             int k;                                                                                                    
             printf("%p\n", &k);                                                                                       
         }                                                                                                             
     }                                                                                                                 
     return 0;                                                                                                         
 }                                                                                                                     

Server.UrlEncode() is there to provide backward compatibility with Classic ASP,

Server.UrlEncode(str);

Is equivalent to:

HttpUtility.UrlEncode(str, Response.ContentEncoding);

The answer from skaffman is definitely the correct answer. All logger methods such as error(), warn(), info(), debug() take Throwable as a second parameter:

try {
...
 } catch (Exception e) {
logger.error("error: ", e);
}

However, you can extract stacktrace as a String as well. Sometimes it could be useful if you wish to take advantage of formatting feature using "{}" placeholder - see method void info(String var1, Object... var2); In this case say you have a stacktrace as String, then you can actually do something like this:

try {
...
 } catch (Exception e) {
String stacktrace = TextUtils.getStacktrace(e);
logger.error("error occurred for usename {} and group {}, details: {}",username, group, stacktrace);
}

This will print parametrized message and the stacktrace at the end the same way it does for method: logger.error("error: ", e);

I actually wrote an open source library that has a Utility for extraction of a stacktrace as a String with an option to smartly filter out some noise out of stacktrace. I.e. if you specify the package prefix that you are interested in your extracted stacktrace would be filtered out of some irrelevant parts and leave you with very consized info. Here is the link to the article that explains what utilities the library has and where to get it (both as maven artifacts and git sources) and how to use it as well. Open Source Java library with stack trace filtering, Silent String parsing Unicode converter and Version comparison See the paragraph "Stacktrace noise filter"

This started happening to my site after I enabled namespace and custom Open Graph actions and objects. Once you enable it, you lose support for standard object types such as bar, or in my case article. (or it's possible Facebook may have deprecated certain types, I'm not 100% sure) When no supported type is specified, Facebook defaults to website.

To fix this what you need to do is go into your app dashboard, select your app, then go to the Open Graph section. Under "Object Types", define your own types, such as "bar."

Next you will have to change your meta tags to look like this:

<meta property="og:type" content="your_namespace:your_object_type" /> 

If you click on "Get Code" next to the object type in the dashboard, Facebook will provide you with an example of meta tags to use.

SQL Server allows the following (be careful to use single quotes instead of double)

UPDATE User
SET UserId = 12345
   , Name = 'J Doe'
   , Location = 'USA'
   , Bio='my bio
spans 
multiple
lines!'
WHERE UserId = 12345

Simply do as below :

button.setOnClickListener{doSomething()}

You can use this javascript plugin

Update 2020, May:

Setting position: absolute and then transform: rotate(45deg) will provide a background:

div {_x000D_
  height: 200px;_x000D_
  width: 200px;_x000D_
  outline: 2px dashed slateBlue;_x000D_
  overflow: hidden;_x000D_
}_x000D_
div img {_x000D_
  position: absolute;_x000D_
  transform: rotate(45deg);_x000D_
  z-index: -1;_x000D_
  top: 40px;_x000D_
  left: 40px;_x000D_
}

<div>_x000D_
  <img src="https://placekitten.com/120/120" />_x000D_
  <h1>Hello World!</h1>_x000D_
</div>

Original Answer:

In my case, the image size is not so large that I cannot have a rotated copy of it. So, the image has been rotated with photoshop. An alternative to photoshop for rotating images is online tool too for rotating images. Once rotated, I'm working with the rotated-image in the background property.

div.with-background {
    background-image: url(/img/rotated-image.png);
    background-size:     contain;
    background-repeat:   no-repeat;
    background-position: top center;
}

Good Luck...

display:none; removes a block from the page as if it were never there. A block cannot be partially displayed; it’s either there or it’s not. The same is true for visibility; you can’t expect a block to be half hidden which, by definition, would be visible! Fortunately, you can use opacity for fading effects instead.
- reference

As an alternatiive CSS solution, you could play with opacity, height and padding properties to achieve the desirable effect:

#header #button:hover > .content {
    opacity:1;
    height: 150px;
    padding: 8px;    
}

#header #button .content {
    opacity:0;
    height: 0;
    padding: 0 8px;
    overflow: hidden;
    transition: all .3s ease .15s;
}

(Vendor prefixes omitted due to brevity.)

Here is a working demo. Also here is a similar topic on SO.

If you are using jQuery UI you have translations for common key codes. In ui/ui/ui.core.js:

$.ui.keyCode = { 
    ...
    ENTER: 13, 
    ...
};

There's also some translations in tests/simulate/jquery.simulate.js but I could not find any in the core JS library. Mind you, I merely grep'ed the sources. Maybe there is some other way to get rid of these magic numbers.

You can also make use of String.charCodeAt and .fromCharCode:

>>> String.charCodeAt('\r') == 13
true
>>> String.fromCharCode(13) == '\r'
true

It looks like there's something else called Afisho_rankimin in your DB so the function is not being created. Try calling your function something else. E.g.

CREATE FUNCTION dbo.Afisho_rankimin1(@emri_rest int)
RETURNS int
AS
   BEGIN
       Declare @rankimi int
       Select @rankimi=dbo.RESTORANTET.Rankimi
       From RESTORANTET
       Where  dbo.RESTORANTET.ID_Rest=@emri_rest
       RETURN @rankimi
  END
  GO

Note that you need to call this only once, not every time you call the function. After that try calling

SELECT dbo.Afisho_rankimin1(5) AS Rankimi 

I think you can do this which get your local file path

    Simple rules:
    A "owns" B = Composition : B has no meaning or purpose in the system 
    without A
    A "uses" B = Aggregation : B exists independently (conceptually) from A
    A "belongs/Have" B= Association; And B exists just have a relation
    Example 1:

    A Company is an aggregation of Employees.
    A Company is a composition of Accounts. When a Company ceases to do 
    business its Accounts cease to exist but its People continue to exist. 
    Employees have association relationship with each other.

    Example 2: (very simplified)
    A Text Editor owns a Buffer (composition). A Text Editor uses a File 
    (aggregation). When the Text Editor is closed,
    the Buffer is destroyed but the File itself is not destroyed.

Hide:

edtPassword.setInputType(InputType.TYPE_CLASS_TEXT);

Show:

edtPassword.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD);                    
edtPassword.setTransformationMethod(PasswordTransformationMethod.getInstance());

In addition to adding C:\Users\yourusername\Anaconda3 and C:\Users\yourusername\Anaconda3\Scripts, as recommended by Raja (above), also add C:\Users\yourusername\Anaconda3\Library\bin to your path variable. This will prevent an SSL error that is bound to happen if you're performing this on a fresh install of Anaconda.

Use the "Edit top 200" option, then click on "Show SQL panel", modify your query with your WHERE clause, and execute the query. You'll be able to edit the results.

app.use is Application level middleware

Bind application-level middleware to an instance of the app object by using the app.use() and app.METHOD() functions, where METHOD is the HTTP method of the request that the middleware function handles (such as GET, PUT, or POST) in lowercase.

you can use to check all requests, for example, you want to check token/access token you need to write a middleware by using app.use to check the token in the request.

This example shows a middleware function with no mount path. The function is executed every time the app receives a request.

var app = express()

app.use(function (req, res, next) {
  console.log('Time:', Date.now())
  next()
})

Same with something more complex...getting the ec2 instance region from within the instance.

INSTANCE_REGION=$(curl -s 'http://169.254.169.254/latest/dynamic/instance-identity/document' | python -c "import sys, json; print json.load(sys.stdin)['region']")

echo $INSTANCE_REGION

A list is immutable by Default, you can use ArrayList instead. like this :

 val orders = arrayListOf<String>()

then you can add/delete items from this like below:

orders.add("Item 1")
orders.add("Item 2")

by default ArrayList is mutable so you can perform the operations on it.

You have wrong database design and you should take a time to read something about database normalization (wikipedia / stackoverflow).

I assume your table looks somewhat like this

TABLE
================================
| group_id | user_ids | name   |
--------------------------------
| 1        | 1,4,6    | group1 |
--------------------------------
| 2        | 4,5,1    | group2 |    

so in your table of user groups, each row represents one group and in user_ids column you have set of user ids assigned to that group.

Normalized version of this table would look like this

GROUP
=====================
| id       | name   |
---------------------
| 1        | group1 |
---------------------
| 2        | group2 |    

GROUP_USER_ASSIGNMENT
======================
| group_id | user_id |
----------------------
| 1        | 1       |
----------------------
| 1        | 4       |
----------------------
| 1        | 6       |
----------------------
| 2        | 4       |
----------------------

Then you can easily select all users with assigned group, or all users in group, or all groups of user, or whatever you can think of. Also, your sql query will work:

/* Your query to select assignments */
SELECT * FROM `group_user_assignment` WHERE user_id IN (1,2,3,4);

/* Select only some users */
SELECT * FROM `group_user_assignment` t1
JOIN `group` t2 ON t2.id = t1.group_id
WHERE user_id IN (1,4);

/* Select all groups of user */
SELECT * FROM `group_user_assignment` t1
JOIN `group` t2 ON t2.id = t1.group_id
WHERE t1.`user_id` = 1;

/* Select all users of group */
SELECT * FROM `group_user_assignment` t1
JOIN `group` t2 ON t2.id = t1.group_id
WHERE t1.`group_id` = 1;

/* Count number of groups user is in */
SELECT COUNT(*) AS `groups_count` FROM `group_user_assignment` WHERE `user_id` = 1;

/* Count number of users in group */
SELECT COUNT(*) AS `users_count` FROM `group_user_assignment` WHERE `group_id` = 1;

This way it will be also easier to update database, when you would like to add new assignment, you just simply insert new row in group_user_assignment, when you want to remove assignment you just delete row in group_user_assignment.

In your database design, to update assignments, you would have to get your assignment set from database, process it and update and then write back to database.

Here is sqlFiddle to play with.

I was having an issue in my project where I was using ng-repeat track by $index but the products were not getting reflecting when data comes from database. My code is as below:

<div ng-repeat="product in productList.productList track by $index">
  <product info="product"></product>
 </div>

In the above code, product is a separate directive to display the product.But i came to know that $index causes issue when we pass data out from the scope. So the data losses and DOM can not be updated.

I found the solution by using product.id as a key in ng-repeat like below:

<div ng-repeat="product in productList.productList track by product.id">
  <product info="product"></product>
 </div>

But the above code again fails and throws the below error when more than one product comes with same id:

angular.js:11706 Error: [ngRepeat:dupes] Duplicates in a repeater are not allowed. Use 'track by' expression to specify unique keys. Repeater

So finally i solved the problem by making dynamic unique key of ng-repeat like below:

<div ng-repeat="product in productList.productList track by (product.id + $index)">
  <product info="product"></product>
 </div>

This solved my problem and hope this will help you in future.

A simpler answer.

function ($quantity) use ($tax, &$total) { .. };

1. The closure is a function assigned to a variable, so you can pass it around
2. A closure is a separate namespace, normally, you can not access variables defined outside of this namespace. There comes the use keyword:
3. use allows you to access (use) the succeeding variables inside the closure.
4. use is early binding. That means the variable values are COPIED upon DEFINING the closure. So modifying $tax inside the closure has no external effect, unless it is a pointer, like an object is.
5. You can pass in variables as pointers like in case of &$total. This way, modifying the value of $total DOES HAVE an external effect, the original variable's value changes.
6. Variables defined inside the closure are not accessible from outside the closure either.
7. Closures and functions have the same speed. Yes, you can use them all over your scripts.

As @Mytskine pointed out probably the best in-depth explanation is the RFC for closures. (Upvote him for this.)

Use grouping.

foo.*?(foo)

Apart from having a Path variable, the directory C:\data\db is mandatory.

Create this and the error shall be solved.

Have implemented @Micah 's solution to generate a trendline with a few changes and thought I'd share:

• Coded as a function
• Option for a polynomial trendline (input order=2)
• Function can also just return the coefficient of determination (R^2, input Rval=True)
• More Numpy array optimisations

Code:

def trendline(xd, yd, order=1, c='r', alpha=1, Rval=False):
    """Make a line of best fit"""

    #Calculate trendline
    coeffs = np.polyfit(xd, yd, order)

    intercept = coeffs[-1]
    slope = coeffs[-2]
    power = coeffs[0] if order == 2 else 0

    minxd = np.min(xd)
    maxxd = np.max(xd)

    xl = np.array([minxd, maxxd])
    yl = power * xl ** 2 + slope * xl + intercept

    #Plot trendline
    plt.plot(xl, yl, c, alpha=alpha)

    #Calculate R Squared
    p = np.poly1d(coeffs)

    ybar = np.sum(yd) / len(yd)
    ssreg = np.sum((p(xd) - ybar) ** 2)
    sstot = np.sum((yd - ybar) ** 2)
    Rsqr = ssreg / sstot

    if not Rval:
        #Plot R^2 value
        plt.text(0.8 * maxxd + 0.2 * minxd, 0.8 * np.max(yd) + 0.2 * np.min(yd),
                 '$R^2 = %0.2f$' % Rsqr)
    else:
        #Return the R^2 value:
        return Rsqr

This worked for me...
I have removed the folders there in .git/worktrees folder and then tried "git delete -D branch-name".

You failed to specify the exact columns (data) to test for normality. Use this instead

shapiro.test(heisenberg$HWWIchg)

The method OfType() will skip the null values:

List<EmailParameterClass> parameterList =
    new List<EmailParameterClass>{param1, param2, param3...};

IList<EmailParameterClass> parameterList_notnull = 
    parameterList.OfType<EmailParameterClass>();

There is a library that provides a better ProcessBuilder, zt-exec. This library can do exactly what you are asking for and more.

Here's what your code would look like with zt-exec instead of ProcessBuilder :

add the dependency :

<dependency>
  <groupId>org.zeroturnaround</groupId>
  <artifactId>zt-exec</artifactId>
  <version>1.11</version>
</dependency>

The code :

new ProcessExecutor()
  .command("somecommand", "arg1", "arg2")
  .redirectOutput(System.out)
  .redirectError(System.err)
  .execute();

Documentation of the library is here : https://github.com/zeroturnaround/zt-exec/

Pointing to Best Practices for Using Strings in the .NET Framework:

• Use StringComparison.Ordinal or StringComparison.OrdinalIgnoreCase for comparisons as your safe default for culture-agnostic string matching.
• Use comparisons with StringComparison.Ordinal or StringComparison.OrdinalIgnoreCase for better performance.
• Use the non-linguistic StringComparison.Ordinal or StringComparison.OrdinalIgnoreCase values instead of string operations based on CultureInfo.InvariantCulture when the comparison is linguistically irrelevant (symbolic, for example).

And finally:

• Do not use string operations based on StringComparison.InvariantCulture in most cases. One of the few exceptions is when you are persisting linguistically meaningful but culturally agnostic data.

$('select').on('change', function (e) {
    var optionSelected = $("option:selected", this);
    var valueSelected = this.value;
    ....
});

Make it simple:

You can apply your style to all the div and re-initialize the last one with :last-child:

for example in CSS:

.yourclass{
    border: 1px solid blue;
}
.yourclass:last-child{
    border: 0;
}

or in SCSS:

.yourclass{
    border: 1px solid rgba(255, 255, 255, 1);
    &:last-child{
        border: 0;
    }
}

• easy to read/remember
• fast to execute
• browser compatible (IE9+ since it's still CSS3)

In some cases, I could prevent Eclipse from crashing during startup by deleting a .snap file in your workspace meta-data (.metadata/.plugins/org.eclipse.core.resources/.snap).

I made a procedure that execute a FOREACH with CURSOR for any table.

Example of use:

CREATE TABLE #A (I INT, J INT)
INSERT INTO #A VALUES (1, 2), (2, 3)
EXEC PRC_FOREACH
    #A --Table we want to do the FOREACH
    , 'SELECT @I, @J' --The execute command, each column becomes a variable in the same type, so DON'T USE SPACES IN NAMES
   --The third variable is the database, it's optional because a table in TEMPB or the DB of the proc will be discovered in code

The result is 2 selects for each row. The syntax of UPDATE and break the FOREACH are written in the hints.

This is the proc code:

CREATE PROC [dbo].[PRC_FOREACH] (@TBL VARCHAR(100) = NULL, @EXECUTE NVARCHAR(MAX)=NULL, @DB VARCHAR(100) = NULL) AS BEGIN

    --LOOP BETWEEN EACH TABLE LINE            

IF @TBL + @EXECUTE IS NULL BEGIN
    PRINT '@TBL: A TABLE TO MAKE OUT EACH LINE'
    PRINT '@EXECUTE: COMMAND TO BE PERFORMED ON EACH FOREACH TRANSACTION'
    PRINT '@DB: BANK WHERE THIS TABLE IS (IF NOT INFORMED IT WILL BE DB_NAME () OR TEMPDB)' + CHAR(13)
    PRINT 'ROW COLUMNS WILL VARIABLE WITH THE SAME NAME (COL_A = @COL_A)'
    PRINT 'THEREFORE THE COLUMNS CANT CONTAIN SPACES!' + CHAR(13)
    PRINT 'SYNTAX UPDATE:

UPDATE TABLE
SET COL = NEW_VALUE
WHERE CURRENT OF MY_CURSOR

CLOSE CURSOR (BEFORE ALL LINES):

IF 1 = 1 GOTO FIM_CURSOR'
    RETURN
END
SET @DB = ISNULL(@DB, CASE WHEN LEFT(@TBL, 1) = '#' THEN 'TEMPDB' ELSE DB_NAME() END)

    --Identifies the columns for the variables (DECLARE and INTO (Next cursor line))

DECLARE @Q NVARCHAR(MAX)

        , C = CASE
            WHEN type_name(system_type_id) IN (''VARCHAR'', ''CHAR'', ''NCHAR'', ''NVARCHAR'') THEN ''('' + REPLACE(CONVERT(VARCHAR(10), max_length), ''-1'', ''MAX'') + '')''
            WHEN type_name(system_type_id) IN (''DECIMAL'', ''NUMERIC'') THEN ''('' + CONVERT(VARCHAR(10), precision) + '', '' + CONVERT(VARCHAR(10), scale) + '')''
            ELSE ''''
        END
    FROM [' + @DB + '].SYS.COLUMNS C WITH(NOLOCK)
    WHERE OBJECT_ID = OBJECT_ID(''[' + @DB + '].DBO.[' + @TBL + ']'')
    )
SELECT
    @DECLARE = STUFF((SELECT A + B + C FROM X FOR XML PATH('''')), 1, 1, '''')
    , @INTO = ''--Read the next line
FETCH NEXT FROM MY_CURSOR INTO '' + STUFF((SELECT A + '''' FROM X FOR XML PATH('''')), 1, 1, '''')'

DECLARE @DECLARE NVARCHAR(MAX), @INTO NVARCHAR(MAX)

I had a similar problem, tried to delete an empty folder via windows explorer. Showed me the not empty error, so I thought I try it via admin cmd, but none of the answers here helped.

After I moved a file into the empty folder. I was able to delete the non empty folder

Let's say you're using this HTML5 layout:

<html>
    <body>
        <header>
            <nav><ul>...</ul></nav>
        </header>
        <article>
            <ul>...</ul>
        </article>
        <footer>
            <ul>...</ul>
        </footer>
    </body>
</html>

You could say in your CSS:

header ul, footer ul, nav ul { list-style-type: none; }

If you're using HTML 4, assign IDs to your DIVs (instead of using the new fancy-pants elements) and change this to:

#header ul, #footer ul, #nav ul { list-style-type: none; }

If you're using a CSS reset stylesheet (like Eric Meyer's), you would actually have to give the list style back, since the reset removes the list style from all lists.

#content ul { list-style-type: disc; margin-left: 1.5em; }

Java programming provides wrapper class for each primitive data types, to convert a primitive data types to correspond object of wrapper class.

Interesting that Firefox will stop further processing of JavaScript after the relocate function. Chrome and IE will continue to display any other alerts and then reload the page. Try it:

<script type="text/javascript">
    alert('foo');
    window.location.reload(true);
    alert('bar');
    window.location.reload(true);
    alert('foobar');
    window.location.reload(true);
</script>

There is a new Gradle task called "cleanBuildCache" just run this task clean the cache then re-build the project.

Here program take time complexity is O(logn) and space complexity O(logn)

public class helper1 {

public static void main(String[] args) {


    int a[] = {1, 2, 3, 4, 5, 7, 8, 9, 10, 11, 12};


    int k = missing(a, 0, a.length);
    System.out.println(k);
}

public static int missing(int[] a, int f, int l) {


    int mid = (l + f) / 2;

    //if first index reached last then no element found 
    if (a.length - 1 == f) {
        System.out.println("missing not find ");
        return 0;
    }

    //if mid with first found 
    if (mid == f) {
        System.out.println(a[mid] + 1);
        return a[mid] + 1;
    }

    if ((mid + 1) == a[mid])
        return missing(a, mid, l);
    else
        return missing(a, f, mid);

  }
 }

Notice that this doesn't work in Windows.
The module pxssh does exactly what you want:
For example, to run 'ls -l' and to print the output, you need to do something like that :

from pexpect import pxssh
s = pxssh.pxssh()
if not s.login ('localhost', 'myusername', 'mypassword'):
    print "SSH session failed on login."
    print str(s)
else:
    print "SSH session login successful"
    s.sendline ('ls -l')
    s.prompt()         # match the prompt
    print s.before     # print everything before the prompt.
    s.logout()

Some links :
Pxssh docs : http://dsnra.jpl.nasa.gov/software/Python/site-packages/Contrib/pxssh.html
Pexpect (pxssh is based on pexpect) : http://pexpect.readthedocs.io/en/stable/

Your reader variable is an iterable, by looping over it you retrieve the rows.

To make it skip one item before your loop, simply call next(reader, None) and ignore the return value.

You can also simplify your code a little; use the opened files as context managers to have them closed automatically:

with open("tmob_notcleaned.csv", "rb") as infile, open("tmob_cleaned.csv", "wb") as outfile:
   reader = csv.reader(infile)
   next(reader, None)  # skip the headers
   writer = csv.writer(outfile)
   for row in reader:
       # process each row
       writer.writerow(row)

# no need to close, the files are closed automatically when you get to this point.

If you wanted to write the header to the output file unprocessed, that's easy too, pass the output of next() to writer.writerow():

headers = next(reader, None)  # returns the headers or `None` if the input is empty
if headers:
    writer.writerow(headers)

Let's assume that you have 2 divs inside of your html file.

<div id="div1">some text</div>
<div id="div2">some other text</div>

The java program itself can't update the content of the html file because the html is related to the client, meanwhile java is related to the back-end.

You can, however, communicate between the server (the back-end) and the client.

What we're talking about is AJAX, which you achieve using JavaScript, I recommend using jQuery which is a common JavaScript library.

Let's assume you want to refresh the page every constant interval, then you can use the interval function to repeat the same action every x time.

setInterval(function()
{
    alert("hi");
}, 30000);

You could also do it like this:

setTimeout(foo, 30000);

Whereea foo is a function.

Instead of the alert("hi") you can perform the AJAX request, which sends a request to the server and receives some information (for example the new text) which you can use to load into the div.

A classic AJAX looks like this:

var fetch = true;
var url = 'someurl.java';
$.ajax(
{
    // Post the variable fetch to url.
    type : 'post',
    url : url,
    dataType : 'json', // expected returned data format.
    data : 
    {
        'fetch' : fetch // You might want to indicate what you're requesting.
    },
    success : function(data)
    {
        // This happens AFTER the backend has returned an JSON array (or other object type)
        var res1, res2;

        for(var i = 0; i < data.length; i++)
        {
            // Parse through the JSON array which was returned.
            // A proper error handling should be added here (check if
            // everything went successful or not)

            res1 = data[i].res1;
            res2 = data[i].res2;

            // Do something with the returned data
            $('#div1').html(res1);
        }
    },
    complete : function(data)
    {
        // do something, not critical.
    }
});

Wherea the backend is able to receive POST'ed data and is able to return a data object of information, for example (and very preferrable) JSON, there are many tutorials out there with how to do so, GSON from Google is something that I used a while back, you could take a look into it.

I'm not professional with Java POST receiving and JSON returning of that sort so I'm not going to give you an example with that but I hope this is a decent start.

C++ has no specific feature to do that. However, if you use a std::vector instead of an array (as you probably should do) then you can specify a value to initialise the vector with.

std::vector <char> v( 100, 42 );

creates a vector of size 100 with all values initialised to 42.

Here is a function that compares your test data against the training data, with the Tf-Idf transformer fitted with the training data. Advantage is that you can quickly pivot or group by to find the n closest elements, and that the calculations are down matrix-wise.

def create_tokenizer_score(new_series, train_series, tokenizer):
    """
    return the tf idf score of each possible pairs of documents
    Args:
        new_series (pd.Series): new data (To compare against train data)
        train_series (pd.Series): train data (To fit the tf-idf transformer)
    Returns:
        pd.DataFrame
    """

    train_tfidf = tokenizer.fit_transform(train_series)
    new_tfidf = tokenizer.transform(new_series)
    X = pd.DataFrame(cosine_similarity(new_tfidf, train_tfidf), columns=train_series.index)
    X['ix_new'] = new_series.index
    score = pd.melt(
        X,
        id_vars='ix_new',
        var_name='ix_train',
        value_name='score'
    )
    return score

train_set = pd.Series(["The sky is blue.", "The sun is bright."])
test_set = pd.Series(["The sun in the sky is bright."])
tokenizer = TfidfVectorizer() # initiate here your own tokenizer (TfidfVectorizer, CountVectorizer, with stopwords...)
score = create_tokenizer_score(train_series=train_set, new_series=test_set, tokenizer=tokenizer)
score

   ix_new   ix_train    score
0   0       0       0.617034
1   0       1       0.862012

In the API I am developing I have a base controller and inside its __construct() method I have the following:

if(isset($_SERVER["CONTENT_TYPE"]) && strpos($_SERVER["CONTENT_TYPE"], "application/json") !== false) {
    $_POST = array_merge($_POST, (array) json_decode(trim(file_get_contents('php://input')), true));
}

This allows me to simply reference the json data as $_POST["var"] when needed. Works great.

That way if an authenticated user connects with a library such a jQuery that sends post data with a default of Content-Type: application/x-www-form-urlencoded or Content-Type: application/json the API will respond without error and will make the API a little more developer friendly.

Hope this helps.

Code Climber and this blog entry provide detailed ways of increasing application's performance.

Compiled query will increase performance of your application, but it has nothing in common with ASP.NET MVC. It will speed up every db application, so it is not really about MVC.

Here's a different approach using CSS instead of JavaScript/AngularJS.

CSS:

.emptymsg {
  display: list-item;
}

li + .emptymsg {
  display: none;
}

Markup:

<ul>
    <li ng-repeat="item in filteredItems"> ... </li>
    <li class="emptymsg">No items found</li>
</ul>

If the list is empty, <li ng-repeat="item in filteredItems">, etc. will get commented out and will become a comment instead of a li element.

You could use an fstream and open it with the std::ios::app flag. Have a look at the code below and it should clear your head.

...
fstream f("filename.ext", f.out | f.app);
f << "any";
f << "text";
f << "written";
f << "wll";
f << "be append";
...

You can find more information about the open modes here and about fstreams here.

I have stopped on the script like below (as I have only one non-clustered unique index in this table):

declare @table_name nvarchar(256)  
declare @col_name nvarchar(256)  
declare @Command  nvarchar(1000)  

set @table_name = N'users'
set @col_name = N'login'

select @Command = 'ALTER TABLE ' + @table_name + ' drop constraint ' + d.name
    from sys.tables t join sys.indexes d on d.object_id = t.object_id  
    where t.name = @table_name and d.type=2 and d.is_unique=1

--print @Command

execute (@Command)

Has anyone comments if this solution is acceptable? Any pros and cons?

Thanks.

If a constant is needed in more than one class, I put it in config/initializers/contant.rb always in all caps (list of states below is truncated).

STATES = ['AK', 'AL', ... 'WI', 'WV', 'WY']

They are available through out the application except in model code as such:

    <%= form.label :states, %>
    <%= form.select :states, STATES, {} %>

To use the constant in a model, use attr_accessor to make the constant available.

class Customer < ActiveRecord::Base
    attr_accessor :STATES

    validates :state, inclusion: {in: STATES, message: "-- choose a State from the drop down list."}
end

From the official document:

"Visual Studio Code is unable to watch for file changes in this large workspace" (error ENOSPC)

When you see this notification, it indicates that the VS Code file watcher is running out of handles because the workspace is large and contains many files. The current limit can be viewed by running:

cat /proc/sys/fs/inotify/max_user_watches

The limit can be increased to its maximum by editing

/etc/sysctl.conf

and adding this line to the end of the file:

fs.inotify.max_user_watches=524288

The new value can then be loaded in by running

sudo sysctl -p

Note that Arch Linux works a little differently, See Increasing the amount of inotify watchers for details.

While 524,288 is the maximum number of files that can be watched, if you're in an environment that is particularly memory constrained, you may wish to lower the number. Each file watch takes up 540 bytes (32-bit) or ~1kB (64-bit), so assuming that all 524,288 watches are consumed, that results in an upper bound of around 256MB (32-bit) or 512MB (64-bit).

Another option

is to exclude specific workspace directories from the VS Code file watcher with the files.watcherExclude setting. The default for files.watcherExclude excludes node_modules and some folders under .git, but you can add other directories that you don't want VS Code to track.

"files.watcherExclude": {
    "**/.git/objects/**": true,
    "**/.git/subtree-cache/**": true,
    "**/node_modules/*/**": true
  }

I wanted to combine a couple of posts to make a full answer of this since it does appear to be a few steps.

1. Above advice by @madtracey

/etc/mysql/my.cnf or /etc/mysql/mysql.conf.d/mysqld.cnf

[mysql]
default-character-set=utf8mb4

[mysqld_safe]
socket          = /var/run/mysqld/mysqld.sock
nice            = 0

[mysqld]
##
character-set-server=utf8mb4
collation-server=utf8mb4_unicode_ci
init_connect='SET NAMES utf8mb4'
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

Again from advice above all jdbc connections had characterEncoding=UTF-8and characterSetResults=UTF-8 removed from them

With this set -Dfile.encoding=UTF-8 appeared to make no difference.

I could still not write international text into db getting same failure as above

Now using this how-to-convert-an-entire-mysql-database-characterset-and-collation-to-utf-8

Update all your db to use utf8mb4

ALTER DATABASE YOURDB CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

Run this query that gives you what needs to be rung

SELECT CONCAT(
'ALTER TABLE ',  table_name, ' CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;  ', 
'ALTER TABLE ',  table_name, ' CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;  ')
FROM information_schema.TABLES AS T, information_schema.`COLLATION_CHARACTER_SET_APPLICABILITY` AS C
WHERE C.collation_name = T.table_collation
AND T.table_schema = 'YOURDB'
AND
(C.CHARACTER_SET_NAME != 'utf8mb4'
    OR
 C.COLLATION_NAME not like 'utf8mb4%')

Copy paste output in editor replace all | with nothing post back into mysql when connected to correct db.

That is all that had to be done and all seems to work for me. Not the -Dfile.encoding=UTF-8 is not enabled and it appears to work as expected

E2A Still having an issue ? I certainly am in production so it turns out you do need to check over what has been done by above, since it sometimes does not work, here is reason and fix in this scenario:

show create table user

  `password` varchar(255) CHARACTER SET latin1 NOT NULL,
  `username` varchar(255) CHARACTER SET latin1 NOT NULL,

You can see some are still latin attempting to manually update the record:

ALTER TABLE user CONVERT TO CHARACTER SET utf8mb4;
ERROR 1071 (42000): Specified key was too long; max key length is 767 bytes

So let's narrow it down:

mysql> ALTER TABLE user change username username varchar(255) CHARACTER SET utf8mb4 not NULL;
ERROR 1071 (42000): Specified key was too long; max key length is 767 bytes
mysql> ALTER TABLE user change username username varchar(100) CHARACTER SET utf8mb4 not NULL;
Query OK, 5 rows affected (0.01 sec)

In short I had to reduce the size of that field in order to get the update to work.

Now when I run:

mysql> ALTER TABLE user CONVERT TO CHARACTER SET utf8mb4;
Query OK, 5 rows affected (0.01 sec)
Records: 5  Duplicates: 0  Warnings: 0

It all works

my solution, hope help
custom ObjectMapper and config to spring xml(register message conveters)

I'm not sure why the way you did it doesn't work, but I usually do it with the spyOn function. Something like this:

describe('Testing remote call returning promise', function() {
  var myService;

  beforeEach(module('app.myService'));

  beforeEach(inject( function(_myService_, myOtherService, $q){
    myService = _myService_;
    spyOn(myOtherService, "makeRemoteCallReturningPromise").and.callFake(function() {
        var deferred = $q.defer();
        deferred.resolve('Remote call result');
        return deferred.promise;
    });
  }

  it('can do remote call', inject(function() {
    myService.makeRemoteCall()
      .then(function() {
        console.log('Success');
      });    
  }));

Also remember that you will need to make a $digest call for the then function to be called. See the Testing section of the $q documentation.

------EDIT------

After looking closer at what you're doing, I think I see the problem in your code. In the beforeEach, you're setting myOtherServiceMock to a whole new object. The $provide will never see this reference. You just need to update the existing reference:

beforeEach(inject( function(_myService_, $q){
    myService = _myService_;
    myOtherServiceMock.makeRemoteCallReturningPromise = function() {
        var deferred = $q.defer();
        deferred.resolve('Remote call result');
        return deferred.promise;   
    };
  }

Note x += y is not the same as x = x + y in some situations where an additional operator is included because of the operator precedence combined with the fact that the right hand side is always evaluated first, e.g.

>>> x = 2
>>> x += 2 and 1
>>> x
3

>>> x = 2
>>> x = x + 2 and 1
>>> x
1

Note the first case expand to:

>>> x = 2
>>> x = x + (2 and 1)
>>> x
3

You are more likely to encounter this in the 'real world' with other operators, e.g.

x *= 2 + 1 == x = x * (2 + 1) != x = x * 2 + 1

You can accomplish this using man-in-the-middle techniques with dynamic SSL generation. Take a look at mitmproxy - it's a Python based, SSL-capable MITM proxy.

Usage: If you're going to store information that you want to access on different web pages, you can use SessionState

If you want to store information that you want to access from the same page, then you can use Viewstate

Storage The Viewstate is stored within the page itself (in encrypted text), while the Sessionstate is stored in the server.

The SessionState will clear in the following conditions

1. Cleared by programmer
2. Cleared by user
3. Timeout

It is a good practice get the amount you need to store first then initialize the array.

for example, you would ask the user how many data he need to store and then initialize it, or query the component or argument of how many you need to store. if you want a dynamic array you could use ArrayList() and use al.add(); function to keep adding, then you can transfer it to a fixed array.

//Initialize ArrayList and cast string so ArrayList accepts strings (or anything
ArrayList<string> al = new ArrayList(); 
//add a certain amount of data
for(int i=0;i<x;i++)
{
  al.add("data "+i); 
}

//get size of data inside
int size = al.size(); 
//initialize String array with the size you have
String strArray[] = new String[size]; 
//insert data from ArrayList to String array
for(int i=0;i<size;i++)
{
  strArray[i] = al.get(i);
}

doing so is redundant but just to show you the idea, ArrayList can hold objects unlike other primitive data types and are very easy to manipulate, removing anything from the middle is easy as well, completely dynamic.same with List and Stack

if(window.location.href.indexOf("?added-to-cart=555") >= 0)

It's window.location.href, not window.location.

This is the correct way to change btn color.

 .btn-primary:not(:disabled):not(.disabled).active, 
    .btn-primary:not(:disabled):not(.disabled):active, 
    .show>.btn-primary.dropdown-toggle{
        color: #fff;
        background-color: #F7B432;
        border-color: #F7B432;
    }

I solve the issue which gives below written error:
Error:
The authenticity of host 'XXX.XXX.XXX' can't be established.
RSA key fingerprint is 09:6c:ef:cd:55:c4:4f:ss:5a:88:46:0a:a9:27:83:89.

Solution:
1. install any openSSH tool.
2. run command ssh
3. it will ask for do u add this host like. accept YES.
4. This host will add in the known host list.
5. Now you are able to connect with this host.

This solution is working now......

I believe the following should work with many well-behaved classed in Python:

def copy(obj):
    return type(obj)(obj)

(Of course, I am not talking here about "deep copies," which is a different story, and which may be not a very clear concept -- how deep is deep enough?)

According to my tests with Python 3, for immutable objects, like tuples or strings, it returns the same object (because there is no need to make a shallow copy of an immutable object), but for lists or dictionaries it creates an independent shallow copy.

Of course this method only works for classes whose constructors behave accordingly. Possible use cases: making a shallow copy of a standard Python container class.

GPL-compiled ffmpeg can be used from non-GPL program (commercial project) only if it is invoked in the separate process as command line utility; all wrappers that are linked with ffmpeg library (including Microsoft's FFMpegInterop) can use only LGPL build of ffmpeg.

You may try my .NET wrapper for FFMpeg: Video Converter for .NET (I'm an author of this library). It embeds FFMpeg.exe into the DLL for easy deployment and doesn't break GPL rules (FFMpeg is NOT linked and wrapper invokes it in the separate process with System.Diagnostics.Process).

The browser only allows numerical inputs when the type is set to "number". Details here.

You can use the type="text" and filter out any other than numerical input using JavaScript like descripted here

Edit (for ASP.NET)

After you edited your question it's cler you're using ASP.NET. Things are pretty different there (because in that case a roundtrip to server is pretty discouraged). You can do same things with JavaScript (but to handle globalization with toUpperCase() may be a pain) or you can use CSS classes (relying on browsers implementation). Simply declare this CSS rule:

.upper-case
{
    text-transform: uppercase
}

And add upper-case class to your text-box:

<asp:TextBox ID="TextBox1" CssClass="upper-case" runat="server"/>

General (Old) Answer

but it capitalize characters after pressing Enter key.

It depends where you put that code. If you put it in, for example, TextChanged event it'll make upper case as you type.

You have a property that do exactly what you need: CharacterCasing:

TextBox1.CharacterCasing = CharacterCasing.Upper;

It works more or less but it doesn't handle locales very well. For example in German language ß is SS when converted in upper case (Institut für Deutsche Sprache) and this property doesn't handle that.

You may mimic CharacterCasing property adding this code in KeyPress event handler:

e.KeyChar = Char.ToUpper(e.KeyChar);

Unfortunately .NET framework doesn't handle this properly and upper case of sharp s character is returned unchanged. An upper case version of ß exists and it's ? and it may create some confusion, for example a word containing "ss" and another word containing "ß" can't be distinguished if you convert in upper case using "SS"). Don't forget that:

However, in 2010 the use of the capital sharp s became mandatory in official documentation when writing geographical names in all-caps.

There isn't much you can do unless you add proper code for support this (and others) subtle bugs in .NET localization. Best advice I can give you is to use a custom dictionary per each culture you need to support.

Finally don't forget that this transformation may be confusing for your users: in Turkey, for example, there are two different versions of i upper case letter.

If text processing is important in your application you can solve many issues using specialized DLLs for each locale you support like Word Processors do.

What I usually do is to do not use standard .NET functions for strings when I have to deal with culture specific issues (I keep them only for text in invariant culture). I create a Unicode class with static methods for everything I need (character counting, conversions, comparison) and many specialized derived classes for each supported language. At run-time that static methods will user current thread culture name to pick proper implementation from a dictionary and to delegate work to that. A skeleton may be something like this:

abstract class Unicode
{
    public static string ToUpper(string text)
    {
        return GetConcreteClass().ToUpperCore(text);
    }

    protected virtual string ToUpperCore(string text)
    {
        // Default implementation, overridden in derived classes if needed
        return text.ToUpper();
    }

    private Dictionary<string, Unicode> _implementations;

    private Unicode GetConcreteClass()
    {
        string cultureName = Thread.Current.CurrentCulture.Name;

        // Check if concrete class has been loaded and put in dictionary
        ...

        return _implementations[cultureName];
    }
}

I'll then have an implementation specific for German language:

sealed class German : Unicode
{
    protected override string ToUpperCore(string text)
    {
        // Very naive implementation, just to provide an example
        return text.ToUpper().Replace("ß", "?");
    }
}

True implementation may be pretty more complicate (not all OSes supports upper case ?) but take as a proof of concept. See also this post for other details about Unicode issues on .NET.

TextView textresult = (TextView)findViewById(R.id.textView1);
textresult.setTextColor(Color.GREEN);

Others have answered your question perfectly, but I just thought I would throw out another way. It's always a good idea to separate HTML markup, CSS styling, and javascript code when possible. The cleanest way to hide something, with that in mind, is using a class. It allows the definition of "hide" to be defined in the CSS where it belongs. Using this method, you could later decide you want the ul to hide by scrolling up or fading away using CSS transition, all without changing your HTML or code. This is longer, but I feel it's a better overall solution.

Demo: http://jsfiddle.net/ThinkingStiff/RkQCF/

HTML:

<a id="showTags" href="#" title="Show Tags">Show All Tags</a>
<ul id="subforms" class="subforums hide"><li>one</li><li>two</li><li>three</li></ul>

CSS:

#subforms {
    overflow-x: visible; 
    overflow-y: visible;
}

.hide {
    display: none; 
}

Script:

document.getElementById( 'showTags' ).addEventListener( 'click', function () {
    document.getElementById( 'subforms' ).toggleClass( 'hide' );
}, false );

Element.prototype.toggleClass = function ( className ) {
    if( this.className.split( ' ' ).indexOf( className ) == -1 ) {
        this.className = ( this.className + ' ' + className ).trim();
    } else {
        this.className = this.className.replace( new RegExp( '(\\s|^)' + className + '(\\s|$)' ), ' ' ).trim();
    };
};

You can use toArray function and then get its length for total records count.

db.CollectionName.aggregate([....]).toArray().length

I know this is old but I was looking for the answer in this post and with jquery you can do it easily and without too much hassle. Just declare your animation keyframe in the css and set the class with the atributes you would like. I my case I used the tada animation from css animate:

.tada {
    -webkit-animation-name: tada;
    animation-name: tada;
    -webkit-animation-duration: 1.25s;
    animation-duration: 1.25s;
    -webkit-animation-fill-mode: both;
    animation-fill-mode: both;
}

I wanted the animation to run every 10 seconds so jquery just adds the class, after 6000ms (enough time for the animation to finish) it removes the class and 4 seconds later it adds the class again and so the animation starts again.

$(document).ready(function() {
  setInterval(function() {

    $(".bottom h2").addClass("tada");//adds the class

    setTimeout(function() {//waits 6 seconds to remove the class
      $(".bottom h2").removeClass("tada");
    }, 6000);

  }, 10000)//repeats the process every 10 seconds
});

Not at all difficult like one guy posted.

You can do it this way (synchronously, but compact):

UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:MyURL]]];

A much better approach is to use Apple's LazyTableImages to preserve interactivity.

According to Nodejs Official Page, you can install&update new node version on windows using Chocolatey or Scoop

Using(Chocolatey):

cinst nodejs
# or for full install with npm
cinst nodejs.install

Using(Scoop):

scoop install nodejs

Also you can download the Windows Installer directly from the nodejs.org web site

Here is how I did this:

first make interface

interface NavigationInterface {
    fun closeActivity()
}

next make sure activity implements interface and overrides interface method(s)

class NotesActivity : AppCompatActivity(), NavigationInterface {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_notes)
        setSupportActionBar(findViewById(R.id.toolbar))
    }

    override fun closeActivity() {
        this.finish()
    }
}

then make sure to create interface listener in fragment

private lateinit var navigationInterface: NavigationInterface

override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
): View? {
    //establish interface communication
    activity?.let {
        instantiateNavigationInterface(it)
    }
    // Inflate the layout for this fragment
    return inflater.inflate(R.layout.fragment_notes_info, container, false)
}

private fun instantiateNavigationInterface(context: FragmentActivity) {
    navigationInterface = context as NavigationInterface
}

then you can make calls like such:

view.findViewById<Button>(R.id.button_second).setOnClickListener {
    navigationInterface.closeActivity()
}

I had this same problem.

Did:

f1 = plt.figure(1)

# code for figure 1

# don't write 'plt.show()' here


f2 = plt.figure(2)

# code for figure 2

plt.show()

Write 'plt.show()' only once, after the last figure. Worked for me.

Well, if you gonna present alternate optimization, we can also go for an iterator:

 static IEnumerable<DateTime> RandomDay()
 {
    DateTime start = new DateTime(1995, 1, 1);
    Random gen = new Random();
    int range = ((TimeSpan)(DateTime.Today - start)).Days;
    while (true)
        yield return  start.AddDays(gen.Next(range));        
}

you could use it like this:

int i=0;
foreach(DateTime dt in RandomDay())
{
    Console.WriteLine(dt);
    if (++i == 10)
        break;
}

An alternative solution to changing the font size is to change the padding. When Python saves your PNG, you can change the layout using the dialogue box that opens. The spacing between the axes, padding if you like can be altered at this stage.

If you are using 64-bit COM components in a web application on IIS, make sure the application pool is set to not allow 32 bit applications (Enable 32-Bit Applications: false in advanced settings)

Try this:

 $(function () {
     $('#row_dim').hide(); // this line you can avoid by adding #row_dim{display:none;} in your CSS
     $('#type').change(function () {
         $('#row_dim').hide();
         if (this.options[this.selectedIndex].value == 'parcel') {
             $('#row_dim').show();
         }
     });
 });

Concurrent Database Access

Same article on my blog(I like formatting more)

I wrote small article which describe how to make access to your android database thread safe.

Assuming you have your own SQLiteOpenHelper.

public class DatabaseHelper extends SQLiteOpenHelper { ... }

Now you want to write data to database in separate threads.

 // Thread 1
 Context context = getApplicationContext();
 DatabaseHelper helper = new DatabaseHelper(context);
 SQLiteDatabase database = helper.getWritableDatabase();
 database.insert(…);
 database.close();

 // Thread 2
 Context context = getApplicationContext();
 DatabaseHelper helper = new DatabaseHelper(context);
 SQLiteDatabase database = helper.getWritableDatabase();
 database.insert(…);
 database.close();

You will get following message in your logcat and one of your changes will not be written.

android.database.sqlite.SQLiteDatabaseLockedException: database is locked (code 5)

This is happening because every time you create new SQLiteOpenHelper object you are actually making new database connection. If you try to write to the database from actual distinct connections at the same time, one will fail. (from answer above)

To use database with multiple threads we need to make sure we are using one database connection.

Let’s make singleton class Database Manager which will hold and return single SQLiteOpenHelper object.

public class DatabaseManager {

    private static DatabaseManager instance;
    private static SQLiteOpenHelper mDatabaseHelper;

    public static synchronized void initializeInstance(SQLiteOpenHelper helper) {
        if (instance == null) {
            instance = new DatabaseManager();
            mDatabaseHelper = helper;
        }
    }

    public static synchronized DatabaseManager getInstance() {
        if (instance == null) {
            throw new IllegalStateException(DatabaseManager.class.getSimpleName() +
                    " is not initialized, call initialize(..) method first.");
        }

        return instance;
    }

    public SQLiteDatabase getDatabase() {
        return new mDatabaseHelper.getWritableDatabase();
    }

}

Updated code which write data to database in separate threads will look like this.

 // In your application class
 DatabaseManager.initializeInstance(new MySQLiteOpenHelper());
 // Thread 1
 DatabaseManager manager = DatabaseManager.getInstance();
 SQLiteDatabase database = manager.getDatabase()
 database.insert(…);
 database.close();

 // Thread 2
 DatabaseManager manager = DatabaseManager.getInstance();
 SQLiteDatabase database = manager.getDatabase()
 database.insert(…);
 database.close();

This will bring you another crash.

java.lang.IllegalStateException: attempt to re-open an already-closed object: SQLiteDatabase

Since we are using only one database connection, method getDatabase() return same instance of SQLiteDatabase object for Thread1 and Thread2. What is happening, Thread1 may close database, while Thread2 is still using it. That’s why we have IllegalStateException crash.

We need to make sure no-one is using database and only then close it. Some folks on stackoveflow recommended to never close your SQLiteDatabase. This will result in following logcat message.

Leak found
Caused by: java.lang.IllegalStateException: SQLiteDatabase created and never closed

Working sample

public class DatabaseManager {

    private int mOpenCounter;

    private static DatabaseManager instance;
    private static SQLiteOpenHelper mDatabaseHelper;
    private SQLiteDatabase mDatabase;

    public static synchronized void initializeInstance(SQLiteOpenHelper helper) {
        if (instance == null) {
            instance = new DatabaseManager();
            mDatabaseHelper = helper;
        }
    }

    public static synchronized DatabaseManager getInstance() {
        if (instance == null) {
            throw new IllegalStateException(DatabaseManager.class.getSimpleName() +
                    " is not initialized, call initializeInstance(..) method first.");
        }

        return instance;
    }

    public synchronized SQLiteDatabase openDatabase() {
        mOpenCounter++;
        if(mOpenCounter == 1) {
            // Opening new database
            mDatabase = mDatabaseHelper.getWritableDatabase();
        }
        return mDatabase;
    }

    public synchronized void closeDatabase() {
        mOpenCounter--;
        if(mOpenCounter == 0) {
            // Closing database
            mDatabase.close();

        }
    }

}

Use it as follows.

SQLiteDatabase database = DatabaseManager.getInstance().openDatabase();
database.insert(...);
// database.close(); Don't close it directly!
DatabaseManager.getInstance().closeDatabase(); // correct way

Every time you need database you should call openDatabase() method of DatabaseManager class. Inside this method, we have a counter, which indicate how many times database is opened. If it equals to one, it means we need to create new database connection, if not, database connection is already created.

The same happens in closeDatabase() method. Every time we call this method, counter is decreased, whenever it goes to zero, we are closing database connection.

Now you should be able to use your database and be sure it's thread safe.

You sure can.

The easiest way to see how you might do this is to browse to the aspx page you want to post to. Then save the source of that page as HTML. Change the action of the form on your new html page to point back to the aspx page you originally copied it from.

Add value tags to your form fields and put the data you want in there, then open the page and hit the submit button.

Only first part of Justin's answer is correct. Using "%.3g" will not work for all cases as .3 is not the precision, but total number of digits. Try it for numbers like 1000.123 and it breaks.

So, I would use what Justin is suggesting:

>>> ('%.4f' % 12340.123456).rstrip('0').rstrip('.')
'12340.1235'
>>> ('%.4f' % -400).rstrip('0').rstrip('.')
'-400'
>>> ('%.4f' % 0).rstrip('0').rstrip('.')
'0'
>>> ('%.4f' % .1).rstrip('0').rstrip('.')
'0.1'

As others have mentioned, you'll probably want to use the BigDecimal class, if you want to have an exact representation of 11.4.

Now, a little explanation into why this is happening:

The float and double primitive types in Java are floating point numbers, where the number is stored as a binary representation of a fraction and a exponent.

More specifically, a double-precision floating point value such as the double type is a 64-bit value, where:

• 1 bit denotes the sign (positive or negative).
• 11 bits for the exponent.
• 52 bits for the significant digits (the fractional part as a binary).

These parts are combined to produce a double representation of a value.

(Source: Wikipedia: Double precision)

For a detailed description of how floating point values are handled in Java, see the Section 4.2.3: Floating-Point Types, Formats, and Values of the Java Language Specification.

The byte, char, int, long types are fixed-point numbers, which are exact representions of numbers. Unlike fixed point numbers, floating point numbers will some times (safe to assume "most of the time") not be able to return an exact representation of a number. This is the reason why you end up with 11.399999999999 as the result of 5.6 + 5.8.

When requiring a value that is exact, such as 1.5 or 150.1005, you'll want to use one of the fixed-point types, which will be able to represent the number exactly.

As has been mentioned several times already, Java has a BigDecimal class which will handle very large numbers and very small numbers.

From the Java API Reference for the BigDecimal class:

Immutable, arbitrary-precision signed decimal numbers. A BigDecimal consists of an arbitrary precision integer unscaled value and a 32-bit integer scale. If zero or positive, the scale is the number of digits to the right of the decimal point. If negative, the unscaled value of the number is multiplied by ten to the power of the negation of the scale. The value of the number represented by the BigDecimal is therefore (unscaledValue × 10^-scale).

There has been many questions on Stack Overflow relating to the matter of floating point numbers and its precision. Here is a list of related questions that may be of interest:

• Why do I see a double variable initialized to some value like 21.4 as 21.399999618530273?
• How to print really big numbers in C++
• How is floating point stored? When does it matter?
• Use Float or Decimal for Accounting Application Dollar Amount?

If you really want to get down to the nitty gritty details of floating point numbers, take a look at What Every Computer Scientist Should Know About Floating-Point Arithmetic.

Think of strings as abstract objects, and char arrays as containers. The string can be any size but the container must be at least 1 more than the string length (to hold the null terminator).

C has very little syntactical support for strings. There are no string operators (only char-array and char-pointer operators). You can't assign strings.

But you can call functions to help achieve what you want.

The strncpy() function could be used here. For maximum safety I suggest following this pattern:

strncpy(p.name, "Jane", 19);
p.name[19] = '\0'; //add null terminator just in case

Also have a look at the strncat() and memcpy() functions.

According to the line debug1: Authentications that can continue: publickey,gssapi-with-mic , ssh password authentication is disabled and apparently you are not using public key authentication.

Login to your server using console and open /etc/ssh/sshd_config file with an editor with root user and look for line PasswordAuthentication then set it's value to yes and finally restart sshd service.

Knockout.js validation is handy but it is not robust. You always have to create server side validation replica. In your case (as you use knockout.js) you are sending JSON data to server and back asynchronously, so you can make user think that he sees client side validation, but in fact it would be asynchronous server side validation.

Take a look at example here upida.cloudapp.net:8080/org.upida.example.knockout/order/create?clientId=1 This is a "Create Order" link. Try to click "save", and play with products. This example is done using upida library (there are spring mvc version and asp.net mvc of this library) from codeplex.

I found the answer I was looking for. The thing to use here is the construct of

\left \middle \right

For example, in this case, two possible solutions are:

$\left( {\frac{a_1}{a_2}} \middle/ {\frac{b_1}{b_2}} \right) $

Or, in case the brackets are not necessary:

$\left. {\frac{a_1}{a_2}} \middle/ {\frac{b_1}{b_2}} \right. $

You can use the CONVERT function to return only the date. See the link(s) below:

Date and Time Manipulation in SQL Server 2000

CAST and CONVERT

The syntax for using the convert function is:

CONVERT ( data_type [ ( length ) ] , expression [ , style ] ) 

vim-autoformat formats your source files using external programs specific for your language, e.g. the "rbeautify" gem for Ruby files, "js-beautify" npm package for JavaScript.

EDIT:

The current version of PIP no longer has this issue. As of right now, version: 7.1.2 is the current version. Here is the PIP link:

https://pypi.python.org/pypi/pip

ORIGINAL FIX:

I got this issue when trying to use pip==1.5.4

This is an issue related to PIP and Python's PYPI trusting SSL certificates. If you look in the PIP log in Mac OS X at: /Users/username/.pip/pip.log it will give you more detail.

My workaround to get PIP back up and running after hours of trying different stuff was to go into my site-packages in Python whether it is in a virtualenv or in your normal site-packages, and get rid of the current PIP version. For me I had pip==1.5.4

I deleted the PIP directory and the PIP egg file. Then I ran

easy_install pip==1.2.1  

This version of PIP doesn't have the SSL issue, and then I was able to go and run my normal pip install -r requirements.txt within my virtualenv to set up all packages that I wanted that were listed in my requirements.txt file.

This is also the recommended hack to get passed the issue by several people on this Google Group that I found:

https://groups.google.com/forum/#!topic/beagleboard/aSlPCNYcVjw

Why not just use:

File file = new File("test.txt");

if (file.length() == 0) {
    // file empty
} else {
    // not empty
}

Is there something wrong with it?

This solutions sounds crazy, but works smooth as honey

import csv

with open('filename', 'wb') as myfile:
    wr = csv.writer(myfile, quoting=csv.QUOTE_ALL,delimiter='\n')
    wr.writerow(mylist)

The file is being written by csvwriter hence csv properties are maintained i.e. comma separated. The delimiter helps in the main part by moving list items to next line, each time.

I do not think a Git commit can record an intention like “stop tracking this file, but do not delete it”.

Enacting such an intention will require intervention outside Git in any repositories that merge (or rebase onto) a commit that deletes the file.

Save a Copy, Apply Deletion, Restore

Probably the easiest thing to do is to tell your downstream users to save a copy of the file, pull your deletion, then restore the file. If they are pulling via rebase and are ‘carrying’ modifications to the file, they will get conflicts. To resolve such conflicts, use git rm foo.conf && git rebase --continue (if the conflicting commit has changes besides those to the removed file) or git rebase --skip (if the conflicting commit has only changed to the removed file).

Restore File as Untracked After Pulling a Commit That Deletes It

If they have already pulled your deletion commit, they can still recover the previous version of the file with git show:

git show @{1}:foo.conf >foo.conf

Or with git checkout (per comment by William Pursell; but remember to re-remove it from the index!):

git checkout @{1} -- foo.conf && git rm --cached foo.conf

If they have taken other actions since pulling your deletion (or they are pulling with rebase into a detached HEAD), they may need something other than @{1}. They could use git log -g to find the commit just before they pulled your deletion.

In a comment, you mention that the file you want to “untrack, but keep” is some kind of configuration file that is required for running the software (directly out of a repository).

Keep File as a ‘Default’ and Manually/Automatically Activate It

If it is not completely unacceptable to continue to maintain the configuration file's content in the repository, you might be able to rename the tracked file from (e.g.) foo.conf to foo.conf.default and then instruct your users to cp foo.conf.default foo.conf after applying the rename commit. Or, if the users already use some existing part of the repository (e.g. a script or some other program configured by content in the repository (e.g. Makefile or similar)) to launch/deploy your software, you could incorporate a defaulting mechanism into the launch/deploy process:

test -f foo.conf || test -f foo.conf.default &&
    cp foo.conf.default foo.conf

With such a defaulting mechanism in place, users should be able to pull a commit that renames foo.conf to foo.conf.default without having to do any extra work. Also, you avoid having to manually copy a configuration file if you make additional installations/repositories in the future.

Rewriting History Requires Manual Intervention Anyway…

If it is unacceptable to maintain the content in the repository then you will likely want to completely eradicate it from history with something like git filter-branch --index-filter …. This amounts to rewriting history, which will require manual intervention for each branch/repository (see “Recovering From Upstream Rebase” section in the git rebase manpage). The special treatment required for your configuration file would be just another step that one must perform while recovering from the rewrite:

1. Save a copy of the configuration file.
2. Recover from the rewrite.
3. Restore the configuration file.

Ignore It to Prevent Recurrence

Whatever method you use, you will probably want to include the configuration filename in a .gitignore file in the repository so that no one can inadvertently git add foo.conf again (it is possible, but requires -f/--force). If you have more than one configuration file, you might consider ‘moving’ them all into a single directory and ignoring the whole thing (by ‘moving’ I mean changing where the program expects to find its configuration files, and getting the users (or the launch/deploy mechanism) to copy/move the files to to their new location; you obviously would not want to git mv a file into a directory that you will be ignoring).

I don't like loops. Based on @Nathan Feger:

md5 = hashlib.md5()
with open(filename, 'rb') as f:
    functools.reduce(lambda _, c: md5.update(c), iter(lambda: f.read(md5.block_size * 128), b''), None)
md5.hexdigest()

It's simple. Just do this:

#include <iostream>
#include <vector>
#include <string.h>

int main(int argc, char *argv[])
{
    std::vector<std::string> argList;
    for(int i=0;i<argc;i++)
        argList.push_back(argv[i]);
    //now you can access argList[n]
}

@Benjamin Lindley You are right. This is not a good solution. Please read the one answered by juanchopanza.

The shortest:

command || exit /b

If you need, you can set the exit code:

command || exit /b 666

And you can also log:

command || echo ERROR && exit /b

Try:

input[type="text"]{
padding:10px 0;}

This is way it remains independent of what textsize has been set for the textbox. You are increasing the height using padding instead

Tons of great suggestions here, just going to throw ZingChart onto the stack for good measure. We recently released a jQuery wrapper for the library that makes it even easier to build and customize charts. The CDN links are in the demo below.

I'm on the ZingChart team and we're here to answer any questions any of you might have!

Node.JS does not fully support ES6 currently, so you can either use asyncawait module or transpile it using Bable.

install

npm install --save asyncawait

helloz.js

var async = require('asyncawait/async');
var await = require('asyncawait/await');

(async (function testingAsyncAwait() {
    await (console.log("Print me!"));
}))();

Could you not have simply added:

align-items:center;

to a new class in your row div. Essentially:

<div class="row align_center">

.align_center { align-items:center; }

var pattern = new RegExp((0|1)[0-9]\/[0-3][0-9]\/(19|20)[0-9]{2});
if(!testdate.match(pattern))
   return false;
else return true;

Using .on() you can define your function once, and it will execute for any dynamically added elements.

for example

$('#staticDiv').on('click', 'yourSelector', function() {
  //do something
});

Alternatively you can use the Protected Attributes gem, however this defeats the purpose of requiring strong params. However if you're upgrading an older app, Protected Attributes does provide an easy pathway to upgrade until such time that you can refactor the attr_accessible to strong params.

You could use .each() with .children() and a selector within the parenthesis:

//Grab Each Instance of Box.
$(".box").each(function(i){

    //For Each Instance, grab a child called .something1. Fade It Out.
    $(this).children(".something1").fadeOut();
});

always make sure to have set your default timezone

date_default_timezone_set('Europe/Berlin');

create DateTime instance, holding the current datetime

$datetime = new DateTime();

create one day interval

$interval = new DateInterval('P1D');

modify the DateTime instance

$datetime->sub($interval);

display the result, or print_r($datetime); for more insight

echo $datetime->format('Y-m-d');

TIP:

If you don't want to change the default timezone, use the DateTimeZone class instead.

$myTimezone = new DateTimeZone('Europe/Berlin');
$datetime->setTimezone($myTimezone); 

or just include it inside the constructor in this form new DateTime("now", $myTimezone);

If you want to create an Android application using c# language you can use Xamarin.
they created this great Cross Platform development tool which enables developers to develop iOS and Android apps in C# language.

Xamarin is offered in different licenses from free to enterprise levels but for not I will be using the starter version which is the free version. It includes the Xamarin Studio which is great start for those who want to try out creating their first apps for Android, they also offer a Business license which lets you develop in Visual Studio so you can use that rich experience similar to developing Web Apps or Windows Apps, then they have this Enterprise which contains everything

Fetch new changes of master and rebase feature branch on top of latest master

git checkout master
git pull
git checkout feature
git pull --rebase origin master
git push origin feature

you can use strbuilder.insert(0,i);

Here is a solution with JQuery:

$(document).ready(function() {
    var $abc = $("#abc");
    $abc.css("height", $abc.attr("scrollHeight"));
})

abc is a teaxtarea.

You're storing the .Text properties of the textboxes directly into the database, this doesn't work. The .Text properties are Strings (i.e. simple text) and not typed as DateTime instances. Do the conversion first, then it will work.

Do this for each date parameter:

Dim bookIssueDate As DateTime = DateTime.ParseExact( txtBookDateIssue.Text, "dd/MM/yyyy", CultureInfo.InvariantCulture ) cmd.Parameters.Add( New OleDbParameter("@Date_Issue", bookIssueDate ) ) 

Note that this code will crash/fail if a user enters an invalid date, e.g. "64/48/9999", I suggest using DateTime.TryParse or DateTime.TryParseExact, but implementing that is an exercise for the reader.

That doesn't work because the second parameter should be a mapped entity and of course Integer is not a persistent class (since it doesn't have the @Entity annotation on it).

for you you should do the following:

Query q = em.createNativeQuery("select id from users where username = :username");
q.setParameter("username", "lt");
List<BigDecimal> values = q.getResultList();

or if you want to use HQL you can do something like this:

Query q = em.createQuery("select new Integer(id) from users where username = :username");
q.setParameter("username", "lt");
List<Integer> values = q.getResultList();

I know this is, very, old question, and I have similar situation few days ago.

Problem was, in my table are approx. 10000 rows, so looping trough DataTable rows was very slow.

Finally, I found much faster solution, where I make copy of source DataTable with desired results, clear source DataTable and merge results from temporary DataTable into source one.

note : instead search for Joe in DataRow called name You have to search for all records whose not have name Joe (little opposite way of searching)

There is example (vb.net) :

'Copy all rows into tmpTable whose not contain Joe in name DataRow
Dim tmpTable As DataTable = drPerson.Select("name<>'Joe'").CopyToTable
'Clear source DataTable, in Your case dtPerson
dtPerson.Clear()
'merge tmpTable into dtPerson (rows whose name not contain Joe)
dtPerson.Merge(tmpTable)
tmpTable = Nothing

I hope so this shorter solution will help someone.

There is c# code (not sure is it correct because I used online converter :( ):

//Copy all rows into tmpTable whose not contain Joe in name DataRow
DataTable tmpTable = drPerson.Select("name<>'Joe'").CopyToTable;
//Clear source DataTable, in Your case dtPerson
dtPerson.Clear();
//merge tmpTable into dtPerson (rows whose name not contain Joe)
dtPerson.Merge(tmpTable);
tmpTable = null;

Of course, I used Try/Catch in case if there is no result (for example, if Your dtPerson don't contain name Joe it will throw exception), so You do nothing with Your table, it stays unchanged.

From help set :

  -e  Exit immediately if a command exits with a non-zero status.

But it's considered bad practice by some (bash FAQ and irc freenode #bash FAQ authors). It's recommended to use:

trap 'do_something' ERR

to run do_something function when errors occur.

See http://mywiki.wooledge.org/BashFAQ/105

I've tried all solutions below, but nothing work:

• sudo xcodebuild -license or
• Remove the build folder with rm -r build and run react-native run-ios or
• npm start and run react-native run-ios
• Add NSAppTransportSecurity to `

I solved by do this:

• Open host file sudo vi /private/etc/hosts (if you use VSCode, use this sudo code /private/etc/hosts)
• Add three line if it's not exist

127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost

• Run react-native run-ios again.

For me MyProperty" -in $MyObject.PSobject.Properties.Name didn't work, however

$MyObject.PSobject.Properties.Name.Contains("MyProperty")

works

I use MacTex, and my editor is TexShop. It probably has to do with what compiler you are using. When I use pdftex, the command:

\includegraphics[height=60mm, width=100mm]{number2.png}

works fine, but when I use "Tex and Ghostscript", I get the same error as you, about not being able to get the size information. Use pdftex.

Incidentally, you can change this in TexShop from the "Typeset" menu.

Hope this helps.

In mechanical terms a COMMIT makes a transaction. That is, a transaction is all the activity (one or more DML statements) which occurs between two COMMIT statements (or ROLLBACK).

In Oracle a DDL statement is a transaction in its own right simply because an implicit COMMIT is issued before the statement is executed and again afterwards. TRUNCATE is a DDL command so it doesn't need an explicit commit because calling it executes an implicit commit.

From a system design perspective a transaction is a business unit of work. It might consist of a single DML statement or several of them. It doesn't matter: only full transactions require COMMIT. It literally does not make sense to issue a COMMIT unless or until we have completed a whole business unit of work.

This is a key concept. COMMITs don't just release locks. In Oracle they also release latches, such as the Interested Transaction List. This has an impact because of Oracle's read consistency model. Exceptions such as ORA-01555: SNAPSHOT TOO OLD or ORA-01002: FETCH OUT OF SEQUENCE occur because of inappropriate commits. Consequently, it is crucial for our transactions to hang onto locks for as long as they need them.

I am using Eclipse 3.5.1 on Ubuntu. After rebooting my machine my projects in PHP Explorer view were giving the warning that the .project file was missing. The problem was that the external directory where my projects are hosted was not mounted on reboot. So I did a mount -a from the command line and the Eclipse recognized the files.

First, hstore is a contrib module, which only allows you to store key => value pairs, where keys and values can only be texts (however values can be sql NULLs too).

Both json & jsonb allows you to store a valid JSON value (defined in its spec).

F.ex. these are valid JSON representations: null, true, [1,false,"string",{"foo":"bar"}], {"foo":"bar","baz":[null]} - hstore is just a little subset compared to what JSON is capable (but if you only need this subset, it's fine).

The only difference between json & jsonb is their storage:

• json is stored in its plain text format, while
• jsonb is stored in some binary representation

There are 3 major consequences of this:

• jsonb usually takes more disk space to store than json (sometimes not)
• jsonb takes more time to build from its input representation than json
• json operations take significantly more time than jsonb (& parsing also needs to be done each time you do some operation at a json typed value)

When jsonb will be available with a stable release, there will be two major use cases, when you can easily select between them:

1. If you only work with the JSON representation in your application, PostgreSQL is only used to store & retrieve this representation, you should use json.
2. If you do a lot of operations on the JSON value in PostgreSQL, or use indexing on some JSON field, you should use jsonb.

yes it's possible to print a string to the console.

#include "stdafx.h"
#include <string>
#include <iostream>

using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
    string strMytestString("hello world");
    cout << strMytestString;
    return 0;
}

stdafx.h isn't pertinent to the solution, everything else is.

I've been searching for a workaround for this for a bit - and the only thing I have found is to use URL rewrites to read the "anchor". I found in the apache docs here http://httpd.apache.org/docs/2.2/rewrite/advanced.html the following...

By default, redirecting to an HTML anchor doesn't work, because mod_rewrite escapes the # character, turning it into %23. This, in turn, breaks the redirection.

Solution: Use the [NE] flag on the RewriteRule. NE stands for No Escape.

Discussion: This technique will of course also work with other special characters that mod_rewrite, by default, URL-encodes.

It may have other caveats and what not ... but I think that at least doing something with the # on the server is possible.

Try it :

$(function () {
     $('#datetimepicker').datetimepicker({  minDate:new Date()});
});

Using CROSS APPLY:

SELECT ID, Col1, Col2, Col3, MinValue
FROM YourTable
CROSS APPLY (SELECT MIN(d) AS MinValue FROM (VALUES (Col1), (Col2), (Col3)) AS a(d)) A

SQL Fiddle

Swift 3 solution:

let singleTap = UITapGestureRecognizer(target: self, action:#selector(self.singleTapAction(_:)))
singleTap.numberOfTapsRequired = 1
view.addGestureRecognizer(singleTap)

let doubleTap = UITapGestureRecognizer(target: self, action:#selector(self.doubleTapAction(_:)))
doubleTap.numberOfTapsRequired = 2
view.addGestureRecognizer(doubleTap)

singleTap.require(toFail: doubleTap)

In the code line singleTap.require(toFail: doubleTap) we are forcing the single tap to wait and ensure that the tap event is not a double tap.

for OrderedDict() you can access the elements by indexing by getting the tuples of (key,value) pairs as follows or using '.values()'

>>> import collections
>>> d = collections.OrderedDict()
>>> d['foo'] = 'python'
>>> d['bar'] = 'spam'
>>> d.items()
[('foo', 'python'), ('bar', 'spam')]
>>>d.values()
odict_values(['python','spam'])
>>>list(d.values())
['python','spam']

Example Project

I finally got a proof-of-concept project to work, so I will share it here.

Set up the layout

The layout is set up like this, where the light grey area is the VideoView.

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.videotest.MainActivity">

    <VideoView
        android:id="@+id/videoview"
        android:layout_width="300dp"
        android:layout_height="200dp"/>

    <Button
        android:text="Play"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/videoview"
        android:onClick="onButtonClick"
        android:id="@+id/button"/>

</RelativeLayout>

Prepare video clip

According to the documentation, Android should support mp4 H.264 playback (decoding) for all API levels. However, there seem to be a lot of factors that affect whether an actual video will play or not. The most in depth answer I could find that told how to encode the videos is here. It uses the powerful ffmpeg command line tool to do the conversion to something that should be playable on all (hopefully?) Android devices. Read the answer I linked to for more explanation. I used a slightly modified version because I was getting errors with the original version.

ffmpeg -y -i input_file.avi -s 432x320 -b:v 384k -vcodec libx264 -flags +loop+mv4 -cmp 256 -partitions +parti4x4+parti8x8+partp4x4+partp8x8 -subq 6 -trellis 0 -refs 5 -bf 0 -coder 0 -me_range 16 -g 250 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -qmin 10 -qmax 51 -qdiff 4 -c:a aac -ac 1 -ar 16000 -r 13 -ab 32000 -aspect 3:2 -strict -2 output_file.mp4

I would definitely read up a lot more on each of those parameters to see which need adjusting as far as video and audio quality go.

Next, rename output_file.mp4 to test.mp4 and put it in your Android project's /res/raw folder. Create the folder if it doesn't exist already.

Code

There is not much to the code. The video plays when the "Play" button is clicked. Thanks to this answer for help.

MainActivity.java

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    public void onButtonClick(View v) {
        VideoView videoview = (VideoView) findViewById(R.id.videoview);
        Uri uri = Uri.parse("android.resource://"+getPackageName()+"/"+R.raw.test);
        videoview.setVideoURI(uri);
        videoview.start();
    }
}

Finished

That's all. You should be able play your video clip on the simulator or a real device now.

I realize this question was asked a long time ago, but I came here looking for answers and wasn't satisfied with anything I could find. I finally found the answer here:

https://www.tutorialsteacher.com/mvc/htmlhelper-dropdownlist-dropdownlistfor

To get the results from the form, use the FormCollection and then pull each individual value out by it's model name thus:

yourRecord.FieldName = Request.Form["FieldNameInModel"];

As far as I could tell it makes absolutely no difference what argument name you give to the FormCollection - use Request.Form["NameFromModel"] to retrieve it.

No, I did not dig down to see how th4e magic works under the covers. I just know it works...

I hope this helps somebody avoid the hours I spent trying different approaches before I got it working.

For the few who may have (due to SEO complications) ended here trying to calculate the angle between two lines in python, as in (x0, y0), (x1, y1) geometrical lines, there is the below minimal solution (uses the shapely module, but can be easily modified not to):

from shapely.geometry import LineString
import numpy as np

ninety_degrees_rad = 90.0 * np.pi / 180.0

def angle_between(line1, line2):
    coords_1 = line1.coords
    coords_2 = line2.coords

    line1_vertical = (coords_1[1][0] - coords_1[0][0]) == 0.0
    line2_vertical = (coords_2[1][0] - coords_2[0][0]) == 0.0

    # Vertical lines have undefined slope, but we know their angle in rads is = 90° * p/180
    if line1_vertical and line2_vertical:
        # Perpendicular vertical lines
        return 0.0
    if line1_vertical or line2_vertical:
        # 90° - angle of non-vertical line
        non_vertical_line = line2 if line1_vertical else line1
        return abs((90.0 * np.pi / 180.0) - np.arctan(slope(non_vertical_line)))

    m1 = slope(line1)
    m2 = slope(line2)

    return np.arctan((m1 - m2)/(1 + m1*m2))

def slope(line):
    # Assignments made purely for readability. One could opt to just one-line return them
    x0 = line.coords[0][0]
    y0 = line.coords[0][1]
    x1 = line.coords[1][0]
    y1 = line.coords[1][1]
    return (y1 - y0) / (x1 - x0)

And the use would be

>>> line1 = LineString([(0, 0), (0, 1)]) # vertical
>>> line2 = LineString([(0, 0), (1, 0)]) # horizontal
>>> angle_between(line1, line2)
1.5707963267948966
>>> np.degrees(angle_between(line1, line2))
90.0

I noticed it myself, and found the files inside the backup folder. You can check where it is using Menu:Settings -> Preferences -> Backup. Note : My NPP installation is portable, and on Windows, so YMMV.

With SharePoint 2013 new library, I managed to do something like this:

private void UploadToSharePoint(string p, out string newUrl)  //p is path to file to load
{
    string siteUrl = "https://myCompany.sharepoint.com/site/";
    //Insert Credentials
    ClientContext context = new ClientContext(siteUrl);

    SecureString passWord = new SecureString();
    foreach (var c in "mypassword") passWord.AppendChar(c);
    context.Credentials = new SharePointOnlineCredentials("myUserName", passWord);
    Web site = context.Web;

    //Get the required RootFolder
    string barRootFolderRelativeUrl = "Shared Documents/foo/bar";
    Folder barFolder = site.GetFolderByServerRelativeUrl(barRootFolderRelativeUrl);

    //Create new subFolder to load files into
    string newFolderName = baseName + DateTime.Now.ToString("yyyyMMddHHmm");
    barFolder.Folders.Add(newFolderName);
    barFolder.Update();

    //Add file to new Folder
    Folder currentRunFolder = site.GetFolderByServerRelativeUrl(barRootFolderRelativeUrl + "/" + newFolderName);
    FileCreationInformation newFile = new FileCreationInformation { Content = System.IO.File.ReadAllBytes(@p), Url = Path.GetFileName(@p), Overwrite = true };
    currentRunFolder.Files.Add(newFile);
    currentRunFolder.Update();

    context.ExecuteQuery();

    //Return the URL of the new uploaded file
    newUrl = siteUrl + barRootFolderRelativeUrl + "/" + newFolderName + "/" + Path.GetFileName(@p);
}

Once you’ve decided to change vim color scheme that you like, you’ll need to configure vim configuration file ~/.vimrc.

For e.g. to use the elflord color scheme just add these lines to your ~/.vimrc file:

colo elflord

For other names of color schemes you can look in /usr/share/vim/vimNN/colors where NN - version of VIM.

That's not possible.

The alternative is using reflection:

 Class.forName("SomeClass").getMethod("someMethod").invoke(null);

Just to be clear, all the answers so far are correct, but the reasoning behind them is not explained very well.

The sumall variable is not yet a string. Parentheticals will not convert to a string (e.g. summ = (int(birthday[0])+int(birthday[1])) still returns an integer. It looks like you most likely intended to type str((int(sumall[0])+int(sumall[1]))), but forgot to. The reason the str() function fixes everything is because it converts anything in it compatible to a string.

Question is about merging two images, however in this specified case you shouldn't do that. You should put Content Image (ie. cover) into <img /> tag, and Style Image into CSS, why?

1. As I said the cover belongs to the content of the document, while that vinyl record and shadow are just a part of the page styles.
2. Such separation is much more convenient to use. User can easily copy that image. It's easier to index by web-spiders.
3. Finally, it's much easier to maintain.

So use a very simple code:

<div class="cover">
   <img src="/content/images/covers/movin-mountains.png" alt="Moving mountains by Pneuma" width="100" height="100" />
</div>

.cover {
    padding: 10px;
    padding-right: 100px;

    background: url(/style/images/cover-background.png) no-repeat;
}

You simply need to specify on which tables to apply the DELETE.

Delete only the deadline rows:

DELETE `deadline` FROM `deadline` LEFT JOIN `job` ....

Delete the deadline and job rows:

DELETE `deadline`, `job` FROM `deadline` LEFT JOIN `job` ....

Delete only the job rows:

DELETE `job` FROM `deadline` LEFT JOIN `job` ....

all:
    echo ${PATH}

Or change PATH just for one command:

all:
    PATH=/my/path:${PATH} cmd

The abs() in the while condition is needed, since, well, it controls the number of iterations (how would you define a negative number of iterations?). You can correct it by inverting the sign of the result if numb is negative.

So this is the modified version of your code. Note I replaced the while loop with a cleaner for loop.

#get user input of numbers as variables
numa, numb = input("please give 2 numbers to multiply seperated with a comma:")

#standing variables
total = 0

#output the total
for count in range(abs(numb)):
    total += numa

if numb < 0:
    total = -total

print total

The issue of adding tooltips to any HTML-Output (not only FontAwesome) is an entire book on its own. ;-)

The default way would be to use the title-attribute:

  <div id="welcomeText" title="So nice to see you!">
    <p>Welcome Harriet</p>
  </div>

or

<i class="fa fa-cog" title="Do you like my fa-coq icon?"></i>

But since most people (including me) do not like the standard-tooltips, there are MANY tools out there which will "beautify" them and offer all sort of enhancements. My personal favourites are jBox and qtip2.

You can open up terminal and simply type

java -version // this will check your jre version
javac -version // this will check your java compiler version if you installed 

this should show you the version of java installed on the system (assuming that you have set the path of the java in system environment).

And if you haven't, add it via

export JAVA_HOME=/path/to/java/jdk1.x

and if you unsure if you have java at all on your system just use find in terminal

i.e. find / -name "java"

you can edit the environment variable file in Ubuntu to set android home globally.

[1] run this command in terminal

sudo -H gedit /etc/environment

[2] your envirmnent file content will look like the below one

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"

[3] in environment file add android sdk path as follows:-

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"
ANDROID_HOME="/home/yourPathTo/Android/Sdk"

[4] then you can check the Android home path in the terminal with the following command:-

echo $ANDROID_HOME

If path is still not set then restart the system to get the applied changes.

Simply put, you need to rewrite all of your database connections and queries.

You are using mysql_* functions which are now deprecated and will be removed from PHP in the future. So you need to start using MySQLi or PDO instead, just as the error notice warned you.

A basic example of using PDO (without error handling):

<?php
$db = new PDO('mysql:host=localhost;dbname=testdb;charset=utf8', 'username', 'password');
$result = $db->exec("INSERT INTO table(firstname, lastname) VAULES('John', 'Doe')");
$insertId = $db->lastInsertId();
?>

A basic example of using MySQLi (without error handling):

$db = new mysqli($DBServer, $DBUser, $DBPass, $DBName);
$result = $db->query("INSERT INTO table(firstname, lastname) VAULES('John', 'Doe')");

Here's a handy little PDO tutorial to get you started. There are plenty of others, and ones about the PDO alternative, MySQLi.

1. Click "Source Control" button on left.
2. See MERGE CHANGES in sidebar.
3. Those files have merge conflicts.

In order to install Android Studio on Ubuntu Studio 14.04 and derivatives, do the following:

Step 1: Open a terminal using the Dash or pressing Ctrl + Alt + T keys.

Step 2: If you have not, add that repository with the following command:

sudo add-apt-repository ppa:paolorotolo/android-studio

Step 3: Update the APT with the command:

sudo apt-get update

Step 4: Now install the program with the command:

sudo apt-get install android-studio

Step 5: Once installed, run the program by typing in Dash:

studio

And this is if copying a single property to another list is needed:

targetList.AddRange(sourceList.Select(i => i.NeededProperty));

Your pointer is pointing to local variable of the function. So as soon as you return from the function, memory gets deallocated. You have to assign memory on heap in order to use it in other functions.

Instead char *rtnPtr = word;

do this char *rtnPtr = malloc(length);

So that it is available in the main function. After it is used free the memory.

This worked for me.

You need to run it twice once for globals followed by locals

for name in dir():
    if not name.startswith('_'):
        del globals()[name]

for name in dir():
    if not name.startswith('_'):
        del locals()[name]

word.matches("^[0-9,;]+$"); you were almost there

limit option, e.g.:

svn log --limit 4

svn log -l 4

Only the last 4 entries

Javascript Function

function AddToCart(id) {
 $.ajax({
   url: '@Url.Action("AddToCart", "ControllerName")',
   type: 'GET',
   dataType: 'json',
   cache: false,
   data: { 'id': id },
   success: function (results) {
        alert(results)
   },
   error: function () {
    alert('Error occured');
   }
   });
   }

Controller Method to call

[HttpGet]
  public JsonResult AddToCart(string id)
  {
    string newId = id;
     return Json(newId, JsonRequestBehavior.AllowGet);
  }

If you only care about that particular machine's traffic, use a capture filter instead, which you can set under Capture -> Options.

host 192.168.1.101

Wireshark will only capture packet sent to or received by 192.168.1.101. This has the benefit of requiring less processing, which lowers the chances of important packets being dropped (missed).

SELECT *
FROM table1, table2

This will join every row in table1 with table2 (the Cartesian product) returning all columns.

rows, columns = list(map(int,input().split())) #input no. of row and column
b=[]
for i in range(rows):
    a=list(map(int,input().split()))
    b.append(a)
print(b)

input

2 3
1 2 3
4 5 6

output [[1, 2, 3], [4, 5, 6]]

This was my solution:

function leadingZero(value) {
  if (value < 10) {
    return "0" + value.toString();
  }
  return value.toString();
}

var targetDate = new Date();
targetDate.setDate(targetDate.getDate());
var dd = targetDate.getDate();
var mm = targetDate.getMonth() + 1;
var yyyy = targetDate.getFullYear();
var dateCurrent = leadingZero(mm) + "/" + leadingZero(dd) + "/" + yyyy;

------------------------Bit late for this answer but may be it will help to someone------------------------

From the Client Side, the easiest way is to remove the token from the storage of browser.

But, What if you want to destroy the token on the Node server -

The problem with JWT package is that it doesn't provide any method or way to destroy the token. You may use different methods with respect to JWT which are mentioned above. But here i go with the jwt-redis.

So in order to destroy the token on the serverside you may use jwt-redis package instead of JWT

This library (jwt-redis) completely repeats the entire functionality of the library jsonwebtoken, with one important addition. Jwt-redis allows you to store the token label in redis to verify validity. The absence of a token label in redis makes the token not valid. To destroy the token in jwt-redis, there is a destroy method

it works in this way :

1) Install jwt-redis from npm

2) To Create -

var redis = require('redis');
var JWTR =  require('jwt-redis').default;
var redisClient = redis.createClient();
var jwtr = new JWTR(redisClient);

jwtr.sign(payload, secret)
    .then((token)=>{
            // your code
    })
    .catch((error)=>{
            // error handling
    });

3) To verify -

jwtr.verify(token, secret);

4) To Destroy -

jwtr.destroy(token)

Note : you can provide expiresIn during signin of token in the same as it is provided in JWT.

May be this will help to someone

And incase you a different delimiter other than comma, you can use that as well.

@Value("#{'${my.config.values}'.split(',')}")
private String[] myValues;   // could also be a List<String>

and

in your application properties you could have

my.config.values=value1, value2, value3

Use this code in Swift 2.0

let strWithFloat = "78.65"
let floatFromString = Double(strWithFloat)

Another simpler way seems to be:

new = pd.DataFrame([old.A, old.B, old.C]).transpose()

where old.column_name will give you a series. Make a list of all the column-series you want to retain and pass it to the DataFrame constructor. We need to do a transpose to adjust the shape.

In [14]:pd.DataFrame([old.A, old.B, old.C]).transpose()
Out[14]: 
   A   B    C
0  4  10  100
1  5  20   50

This one is working well in MS SQL. It transforms varchar to the result of two-decimal-places-limited float.

Select field1, cast(Try_convert(float,(Count(field2)* 100) / 
Try_convert(float, (Select Count(*) From table1))) as decimal(10,2)) as new_field_name 
From table1 
Group By field1, field2;

If you want only digits:

var value = '675-805-714';
var numberPattern = /\d+/g;
value = value.match( numberPattern ).join([]);
alert(value);
//Show: 675805714

Now you get the digits joined

What everyone is forgeting is explaining WHY this happens.

A Char, is basically an integer, but with a pointer in the ASCII table. All characters have a corresponding integer value as you can clearly see when trying to parse it.

Pranay has clearly a different character set, thats why HIS code doesnt work. the only way is

int val = '1' - '0';

because this looks up the integer value in the table of '0' which is then the 'base value' subtracting your number in char format from this will give you the original number.

No, how you are doing it is correct.

http://www.w3.org/MarkUp/html-spec/html-spec_8.html#SEC8.2.2

You could define a macro containing the following code:

Sub DeleteA5X50()   
    Range("A5:X50").Select
    Selection.ClearContents
end sub

Running the macro would select the range A5:x50 on the active worksheet and clear all the contents of the cells within that range.

To leave your formulas intact use the following instead:

Sub DeleteA5X50()   
    Range("A5:X50").Select
    Selection.SpecialCells(xlCellTypeConstants, 23).Select
    Selection.ClearContents
end sub

This will first select the overall range of cells you are interested in clearing the contents from and will then further limit the selection to only include cells which contain what excel considers to be 'Constants.'

You can do this manually in excel by selecting the range of cells, hitting 'f5' to bring up the 'Go To' dialog box and then clicking on the 'Special' button and choosing the 'Constants' option and clicking 'Ok'.

For functional components with hooks

const [searches, setSearches] = useState([]);

// Using .concat(), no wrapper function (not recommended)
setSearches(searches.concat(query));

// Using .concat(), wrapper function (recommended)
setSearches(searches => searches.concat(query));

// Spread operator, no wrapper function (not recommended)
setSearches([...searches, query]);

// Spread operator, wrapper function (recommended)
setSearches(searches => [...searches, query]);

MY PREFERRED METHOD is using fopen,fwrite and fclose [it will cost less CPU]

$f=fopen('myfile.txt','w');
fwrite($f,'new content');
fclose($f);

Warning for those using file_put_contents

It'll affect a lot in performance, for example [on the same class/situation] file_get_contents too: if you have a BIG FILE, it'll read the whole content in one shot and that operation could take a long waiting time

I found that my version of Xcode was too outdated and installing command-line-tools wasn't helping. Here's what I did:

• I completely uninstalled the outdated XCode
• I reinstalled the most recent XCode from the app store
• That was all. Git was restored.

I've found that you can use any subset condition for a given column by wrapping it in []. For instance, you have a df with columns ['Product','Time', 'Year', 'Color']

And let's say you want to include products made before 2014. You could write,

df[df['Year'] < 2014]

To return all the rows where this is the case. You can add different conditions.

df[df['Year'] < 2014][df['Color' == 'Red']

Then just choose the columns you want as directed above. For instance, the product color and key for the df above,

df[df['Year'] < 2014][df['Color'] == 'Red'][['Product','Color']]

i was also facing the same issue, The possible solution is to install the gulp-sass module, but if you will run the below command npm install -g gulp-sass or npm install --save gulp-sass, This is not going to be updated on node-sass project's end.

This version of node-sass is missing (returns a 404) and google web-starter-kit v0.6.5 has depended on it for a long time, since Dec 2016. So, it has been working for a long time and must have just disappeared.

Downloading binary from https://github.com/sass/node-sass/releases/download/v3.13.1/win32-x64-57_binding.node Cannot download "https://github.com/sass/node-sass/releases/download/v3.13.1/win32-x64-57_binding.node":

HTTP error 404 Not Found

The only workaround is to upgrade node-sass: npm i gulp-sass@latest --save-dev to fix the issue.

On Linux, just run below command at terminal:

$ curl --compressed -o- -L https://yarnpkg.com/install.sh | bash

After do this, close the current terminal and open it again. And then, run below command to check yarn current version:

$ yarn --version

Swift doesn't have its own Date type, but you to use the existing Cocoa NSDate type, e.g:

class Date {

    class func from(year: Int, month: Int, day: Int) -> Date {
        let gregorianCalendar = NSCalendar(calendarIdentifier: .gregorian)!

        var dateComponents = DateComponents()
        dateComponents.year = year
        dateComponents.month = month
        dateComponents.day = day

        let date = gregorianCalendar.date(from: dateComponents)!
        return date
    }

    class func parse(_ string: String, format: String = "yyyy-MM-dd") -> Date {
        let dateFormatter = DateFormatter()
        dateFormatter.timeZone = NSTimeZone.default
        dateFormatter.dateFormat = format

        let date = dateFormatter.date(from: string)!
        return date
    }
}

Which you can use like:

var date = Date.parse("2014-05-20")
var date = Date.from(year: 2014, month: 05, day: 20)

Converting Bitmap to File needs to be done in background (NOT IN THE MAIN THREAD) it hangs the UI specially if the bitmap was large

File file;

public class fileFromBitmap extends AsyncTask<Void, Integer, String> {

    Context context;
    Bitmap bitmap;
    String path_external = Environment.getExternalStorageDirectory() + File.separator + "temporary_file.jpg";

    public fileFromBitmap(Bitmap bitmap, Context context) {
        this.bitmap = bitmap;
        this.context= context;
    }

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        // before executing doInBackground
        // update your UI
        // exp; make progressbar visible
    }

    @Override
    protected String doInBackground(Void... params) {

        ByteArrayOutputStream bytes = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
        file = new File(Environment.getExternalStorageDirectory() + File.separator + "temporary_file.jpg");
        try {
            FileOutputStream fo = new FileOutputStream(file);
            fo.write(bytes.toByteArray());
            fo.flush();
            fo.close();
        } catch (IOException e) {
            e.printStackTrace();
        }

        return null;
    }


    @Override
    protected void onPostExecute(String s) {
        super.onPostExecute(s);
        // back to main thread after finishing doInBackground
        // update your UI or take action after
        // exp; make progressbar gone

         sendFile(file);

    }
}

Calling it

new fileFromBitmap(my_bitmap, getApplicationContext()).execute();

you MUST use the file in onPostExecute .

To change directory of file to be stored in cache replace line :

 file = new File(Environment.getExternalStorageDirectory() + File.separator + "temporary_file.jpg");

with :

file  = new File(context.getCacheDir(), "temporary_file.jpg");

Corrected

public static void InsertOrUpdateRange<T, T2>(this T entity, List<T2> updateEntity) 
        where T : class
        where T2 : class
        {
            foreach(var e in updateEntity)
            {
                context.Set<T2>().InsertOrUpdate(e);
            }
        }


        public static void InsertOrUpdate<T, T2>(this T entity, T2 updateEntity) 
        where T : class
        where T2 : class
        {
            if (context.Entry(updateEntity).State == EntityState.Detached)
            {
                if (context.Set<T2>().Any(t => t == updateEntity))
                {
                   context.Set<T2>().Update(updateEntity); 
                }
                else
                {
                    context.Set<T2>().Add(updateEntity);
                }

            }
            context.SaveChanges();
        }

Addition to the accepted answer:

if you are going to use

 @Html.ActionLink("LinkName", "ActionName", "ControllerName", new { @id = idValue, @secondParam= = 2 },null)

this will create actionlink where you can't create new custom attribute or style for the link.

However, the 4th parameter in ActionLink extension will solve that problem. Use the 4th parameter for customization in your way.

 @Html.ActionLink("LinkName", "ActionName", "ControllerName", new { @id = idValue, @secondParam= = 2 }, new { @class = "btn btn-info", @target = "_blank" })

Minor addition to what has been said before. You likely want to return a dataframe. This would be done as

import pypyodbc 
import pandas as pd

cnxn = pypyodbc.connect("Driver={SQL Server Native Client 11.0};"
                        "Server=server_name;"
                        "Database=db_name;"
                        "uid=User;pwd=password")
df = pd.read_sql_query('select * from table', cnxn)

I'm not exactly sure where my problem was, but I believe it was because I was using the same global packages from both npm and Yarn.

I uninstalled all the npm global packages, then when using yarn commands once again, the problem was gone.

To see global packages installed...

for npm:

npm ls -g --depth=0

for Yarn:

yarn global list

I then uninstalled each package I saw in the npm listing, using:

npm uninstall -g <package-name>

Simply extends your java file from AppCompatActivity and do this:

ActionBar actionBar = getSupportActionBar(); // support.v7
actionBar.setTitle(" ");

On windows, you will need to install drivers for the device for adb to recognize it. To see if the drivers are installed, check the device manager. If there is any "unrecognized device" in the device manager, the drivers are not installed. You can usually get the adb drivers from the manufacturers.

You can implement this functionality like this
Firstly, using the ls command pointed to the targeted directory. Later using find command filter the result from it. From your case, it sounds like - always the filename starts with a word file***.txt

ls /some/path/here | find . -name 'file*.txt'   (* represents some wild card search)

Alternative by terminal with no permission

The pg documentation at NOTES say

The path will be interpreted relative to the working directory of the server process (normally the cluster's data directory), not the client's working directory.

So, gerally, using psql or any client, even in a local server, you have problems ... And, if you're expressing COPY command for other users, eg. at a Github README, the reader will have problems ...

The only way to express relative path with client permissions is using STDIN,

When STDIN or STDOUT is specified, data is transmitted via the connection between the client and the server.

as remembered here:

psql -h remotehost -d remote_mydb -U myuser -c \
   "copy mytable (column1, column2) from STDIN with delimiter as ','" \
   < ./relative_path/file.csv

You can try this:

HTML

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

CSS

table {
    border: 1px solid green;
    border-collapse: collapse;
    width:100%;
}

table td {
    border: 1px solid green;
}

table td.shrink {
    white-space:nowrap
}
table td.expand {
    width: 99%
}
