In theory like so:

# BOLD
$ echo -e "\033[1mThis is a BOLD line\033[0m"
This is a BOLD line

# Using tput
tput bold 
echo "This" #BOLD
tput sgr0 #Reset text attributes to normal without clear.
echo "This" #NORMAL

# UNDERLINE
$ echo -e "\033[4mThis is a underlined line.\033[0m"
This is a underlined line. 

But in practice it may be interpreted as "high intensity" color instead.

Can you get away with recreating the staging table from scratch every time the query is executed? If so you could use SELECT ... INTO syntax and let SQL Server worry about creating the table using the correct column types etc.

SELECT *
INTO your_staging_table
FROM enormous_collection_of_views_tables_etc

I solved the same problem of having to reset a form at its pristine state in Angular version 1.0.7 (no $setPristine method)

In my use case, the form, after being filled and submitted must disappear until it is again necessary for filling another record. So I made the show/hide effect by using ng-switch instead of ng-show. As I suspected, with ng-switch, the form DOM sub-tree is completely removed and later recreated. So the pristine state is automatically restored.

I like it because it is simple and clean but it may not be a fit for anybody's use case.

it may also imply some performance issues for big forms (?) In my situation I did not face this problem yet.

You can also use Aragon Package Manager if you prefer a decentralized approach:

1. Using APM: http://blog.aragon.one/using-apm-to-replace-npm-and-other-centralized-package-managers/
2. Deploying APM: https://github.com/aragon/aragonOS#apm

This code is working fine for me,

var a = serializer.Deserialize<List<Entity>>(json);

Use OnCommand event of imagebutton. Within it do

<asp:Button id="Button1" Text="Click" CommandName="Something" CommandArgument="your command arg" OnCommand="CommandBtn_Click" runat="server"/>

Code-behind:

void CommandBtn_Click(Object sender, CommandEventArgs e) 
{    
    switch(e.CommandName)
    {
        case "Something":
            // Do your code
            break;
        default:              
            break; 

    }
}

Following is the util function to get current timestamp in milliseconds:

#include <sys/time.h>

long long current_timestamp() {
    struct timeval te; 
    gettimeofday(&te, NULL); // get current time
    long long milliseconds = te.tv_sec*1000LL + te.tv_usec/1000; // calculate milliseconds
    // printf("milliseconds: %lld\n", milliseconds);
    return milliseconds;
}

About timezone:

gettimeofday() support to specify timezone, I use NULL, which ignore the timezone, but you can specify a timezone, if need.

@Update - timezone

Since the long representation of time is not relevant to or effected by timezone itself, so setting tz param of gettimeofday() is not necessary, since it won't make any difference.

And, according to man page of gettimeofday(), the use of the timezone structure is obsolete, thus the tz argument should normally be specified as NULL, for details please check the man page.

Once you have cloned the repo, you have everything: you can then hg up branchname or hg up tagname to update your working copy.

UP: hg up is a shortcut of hg update, which also has hg checkout alias for people with git habits.

More ad-hoc benchmark results:

$ time php -r 'for ($x = 0;$x < 999999999; $x++){$i = (integer) "-11";}'

Let me give an example in JavaScript, I've fought a lot with that:

/**
 * Calculates the angle (in radians) between two vectors pointing outward from one center
 *
 * @param p0 first point
 * @param p1 second point
 * @param c center point
 */
function find_angle(p0,p1,c) {
    var p0c = Math.sqrt(Math.pow(c.x-p0.x,2)+
                        Math.pow(c.y-p0.y,2)); // p0->c (b)   
    var p1c = Math.sqrt(Math.pow(c.x-p1.x,2)+
                        Math.pow(c.y-p1.y,2)); // p1->c (a)
    var p0p1 = Math.sqrt(Math.pow(p1.x-p0.x,2)+
                         Math.pow(p1.y-p0.y,2)); // p0->p1 (c)
    return Math.acos((p1c*p1c+p0c*p0c-p0p1*p0p1)/(2*p1c*p0c));
}

Bonus: Example with HTML5-canvas

You can use the command wget to download from command line. Specifically, you could use

wget http://download.oracle.com/otn-pub/java/jdk/7u10-b18/jdk-7u10-linux-x64.tar.gz

However because Oracle requires you to accept a license agreement this may not work (and I am currently unable to test it).

Well, this one liner might qualify (uses Guava Ranges)

ContiguousSet<Integer> integerList = ContiguousSet.create(Range.closedOpen(0, 10), DiscreteDomain.integers());
System.out.println(integerList);

This doesn't create a List<Integer>, but ContiguousSet offers much the same functionality, in particular implementing Iterable<Integer> which allows foreach implementation in the same way as List<Integer>.

In older versions (somewhere before Guava 14) you could use this:

ImmutableList<Integer> integerList = Ranges.closedOpen(0, 10).asSet(DiscreteDomains.integers()).asList();
System.out.println(integerList);

Both produce:

[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

Get the value for an associative array property when the property name is an integer:

Starting with an associative array where the property names are integers:

var categories = [
    {"1": "Category 1"},
    {"2": "Category 2"},
    {"3": "Category 3"},
    {"4": "Category 4"}
];

Push items to the array:

categories.push({"2300": "Category 2300"});
categories.push({"2301": "Category 2301"});

Loop through the array and do something with the property value.

for (var i = 0; i < categories.length; i++) {
    for (var categoryid in categories[i]) {
        var category = categories[i][categoryid];
        // Log progress to the console
        console.log(categoryid + ": " + category);
        //  ... do something
    }
}

Console output should look like this:

1: Category 1
2: Category 2
3: Category 3
4: Category 4
2300: Category 2300
2301: Category 2301

As you can see, you can get around the associative array limitation and have a property name be an integer.

NOTE: The associative array in my example is the JSON content you would have if you serialized a Dictionary<string, string>[] object.

Here you can see the difference between the way that deceze offered comparing to the simple array_values approach:

The Array:

$array['a'][0] = array('x' => 1, 'y' => 2, 'z' => 3);
$array['a'][5] = array('x' => 4, 'y' => 5, 'z' => 6);

$array['b'][1] = array('x' => 7, 'y' => 8, 'z' => 9);
$array['b'][7] = array('x' => 10, 'y' => 11, 'z' => 12);

In deceze way, here is your output:

$array = array_map('array_values', $array);
print_r($array);

/* Output */

Array
(
    [a] => Array
        (
            [0] => Array
                (
                    [x] => 1
                    [y] => 2
                    [z] => 3
                )
            [1] => Array
                (
                    [x] => 4
                    [y] => 5
                    [z] => 6
                )
        )
    [b] => Array
        (
            [0] => Array
                (
                    [x] => 7
                    [y] => 8
                    [z] => 9
                )

            [1] => Array
                (
                    [x] => 10
                    [y] => 11
                    [z] => 12
                )
        )
)

And here is your output if you only use array_values function:

$array = array_values($array);
print_r($array);

/* Output */

Array
(
    [0] => Array
        (
            [0] => Array
                (
                    [x] => 1
                    [y] => 2
                    [z] => 3
                )
            [5] => Array
                (
                    [x] => 4
                    [y] => 5
                    [z] => 6
                )
        )
    [1] => Array
        (
            [1] => Array
                (
                    [x] => 7
                    [y] => 8
                    [z] => 9
                )
            [7] => Array
                (
                    [x] => 10
                    [y] => 11
                    [z] => 12
                )
        )
)

If this doesn't work I'm out of ideas. This way you get the 4 columns in both tables (as Bar owns them and Foo uses them to reference Bar) and the generated IDs in both entities. The set of 4 columns has to be unique in Bar so the many-to-one relation doesn't become a many-to-many.

@Embeddable
public class AnEmbeddedObject
{
    @Column(name = "column_1")
    private Long column1;
    @Column(name = "column_2")
    private Long column2;
    @Column(name = "column_3")
    private Long column3;
    @Column(name = "column_4")
    private Long column4;
}

@Entity
public class Foo
{
    @Id
    @Column(name = "id")
    @GeneratedValue(generator = "seqGen")
    @SequenceGenerator(name = "seqGen", sequenceName = "FOO_ID_SEQ", allocationSize = 1)
    private Long id;
    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumns({
        @JoinColumn(name = "column_1", referencedColumnName = "column_1"),
        @JoinColumn(name = "column_2", referencedColumnName = "column_2"),
        @JoinColumn(name = "column_3", referencedColumnName = "column_3"),
        @JoinColumn(name = "column_4", referencedColumnName = "column_4")
    })
    private Bar bar;
}

@Entity
@Table(uniqueConstraints = @UniqueConstraint(columnNames = {
    "column_1",
    "column_2",
    "column_3",
    "column_4"
}))
public class Bar
{
    @Id
    @Column(name = "id")
    @GeneratedValue(generator = "seqGen")
    @SequenceGenerator(name = "seqGen", sequenceName = "BAR_ID_SEQ", allocationSize = 1)
    private Long id;
    @Embedded
    private AnEmbeddedObject anEmbeddedObject;
}

This is minor usage is tilde...

def split_train_test_by_id(data, test_ratio, id_column):
    ids = data[id_column]
    in_test_set = ids.apply(lambda id_: test_set_check(id_, test_ratio)) 
    return data.loc[~in_test_set], data.loc[in_test_set]

the code above is from "Hands On Machine Learning"

you use tilde (~ sign) as alternative to - sign index marker

just like you use minus - is for integer index

ex)

array = [1,2,3,4,5,6]
print(array[-1])

is the samething as

print(array[~1])

First

Make a dir c:\command

Second Make a ll.bat

ll.bat

dir

Third Add to Path C:/commands

You must use prefix "php5.6-" instead of "php5-" as in ubuntu 14.04 and olders:

sudo apt-get install php5.6 php5.6-mcrypt

Add the function ob_end_clean() before call the Output function.

There is no array-construction syntax that ca be used in this context, at least not directly. You can accomplish what you're trying to accomplish by something along the lines of:

Bar::Bar()
{
    static const int inits [] = {4,5,6};
    static const size_t numInits = sizeof(inits)/sizeof(inits[0]);
    std::copy(&inits[0],&inits[numInits],foo);  // be careful that there are enough slots in foo
}

...but you'll need to give Foo a default constructor.

In Python you may use the in operator. You can do stuff like this:

>>> "c" in "abc"
True

Taking this further, you can check for complex structures, like tuples:

>>> (2, 4, 8) in ((1, 2, 3), (2, 4, 8))
True

For me the issue was signing into my Google account on the debug Chrome window. This had been working fine for me until I signed in. Once I signed out of that instance of Chrome AND choose to delete all of my settings via the checkbox, the debugger worked fine again.

My non-debugging instance of Chrome was still signed into Google and unaffected. The main issue is that my lovely plugins are gone from the debug version, but at least I can step through client code again.

It depends which version of Visual Studio:

• In 2002, all projects use .Net 1.0
• In 2003, all projects use .Net 1.1
• In 2005, all projects use .Net 2.0
• In 2008, projects use .Net 2.0, 3.0, or 3.5; you can change the version in Project Properties
• In 2010, projects use .Net 2.0, 3.0, 3.5, or 4.0; you can change the version in Project Properties
• In 2012, projects use .Net 2.0, 3.0, 3.5, 4.0 or 4.5; you can change the version in Project Properties

Newer versions of Visual Studio support many versions of the .Net framework; check your project type and properties.

OK.. We needed to compare a dynamic number of product names...

There's probably a better way... but this works for me...

... because....Strings are just Arrays of characters.... :>}

//  Compare Strings ...  Return Matching Text and Differences with Product IDs...

//  From MySql...
$productID1 = 'abc123';
$productName1 = "EcoPlus Premio Jet 600";   

$productID2 = 'xyz789';
$productName2 = "EcoPlus Premio Jet 800";   

$ProductNames = array(
    $productID1 => $productName1,
    $productID2 => $productName2
);


function compareNames($ProductNames){   

    //  Convert NameStrings to Arrays...    
    foreach($ProductNames as $id => $product_name){
        $Package1[$id] = explode(" ",$product_name);    
    }

    // Get Matching Text...
    $Matching = call_user_func_array('array_intersect', $Package1 );
    $MatchingText = implode(" ",$Matching);

    //  Get Different Text...
    foreach($Package1 as $id => $product_name_chunks){
        $Package2 = array($product_name_chunks,$Matching);
        $diff = call_user_func_array('array_diff', $Package2 );
        $DifferentText[$id] = trim(implode(" ", $diff));
    }

    $results[$MatchingText]  = $DifferentText;              
    return $results;

The first argument to printf() is always a string value, known as a format control string. This string may be regular text, such as

printf("Hello, World\n"); // \n indicates a newline character

or

char greeting[] = "Hello, World\n";
printf(greeting);

This string may also contain one or more conversion specifiers; these conversion specifiers indicate that additional arguments have been passed to printf(), and they specify how to format those arguments for output. For example, I can change the above to

char greeting[] = "Hello, World";
printf("%s\n", greeting);

The "%s" conversion specifier expects a pointer to a 0-terminated string, and formats it as text.

For signed decimal integer output, use either the "%d" or "%i" conversion specifiers, such as

printf("%d\n", addNumber(a,b));

You can mix regular text with conversion specifiers, like so:

printf("The result of addNumber(%d, %d) is %d\n", a, b, addNumber(a,b));

Note that the conversion specifiers in the control string indicate the number and types of additional parameters. If the number or types of additional arguments passed to printf() don't match the conversion specifiers in the format string then the behavior is undefined. For example:

printf("The result of addNumber(%d, %d) is %d\n", addNumber(a,b));

will result in anything from garbled output to an outright crash.

There are a number of additional flags for conversion specifiers that control field width, precision, padding, justification, and types. Check your handy C reference manual for a complete listing.

Like @maerics said, your target machine and browser will determine performance.

But for some real world numbers, on my 2017 enterprise Chromebook, running the operation:

console.time();
Array(x).fill(0).filter(x => x < 6).length
console.timeEnd();

• x=5e4 takes 16ms, good enough for 60fps
• x=4e6 takes 250ms, which is noticeable but not a big deal
• x=3e7 takes 1300ms, which is pretty bad
• x=4e7 takes 11000ms and allocates an extra 2.5GB of memory

So around 30 million elements is a hard upper limit, because the javascript VM falls off a cliff at 40 million elements and will probably crash the process.

EDIT: In the code above, I'm actually filling the array with elements and looping over them, simulating the minimum of what an app might want to do with an array. If you just run Array(2**32-1) you're creating a sparse array that's closer to an empty JavaScript object with a length, like {length: 4294967295}. If you actually tried to use all those 4 billion elements, you'll definitely your user's javascript process.

I have used a method to test if any specific key is pressed by storing the currently pressed key codes in an array:

var keysPressed = [],
    shiftCode = 16;

$(document).on("keyup keydown", function(e) {
    switch(e.type) {
        case "keydown" :
            keysPressed.push(e.keyCode);
            break;
        case "keyup" :
            var idx = keysPressed.indexOf(e.keyCode);
            if (idx >= 0)
                keysPressed.splice(idx, 1);
            break;
    }
});

$("a.shifty").on("click", function(e) {
    e.preventDefault();
    console.log("Shift Pressed: " + (isKeyPressed(shiftCode) ? "true" : "false"));
});

function isKeyPressed(code) {
    return keysPressed.indexOf(code) >= 0;
}

Here is the jsfiddle

What is a LATERAL join?

The feature was introduced with PostgreSQL 9.3.
Quoting the manual:

Subqueries appearing in FROM can be preceded by the key word LATERAL. This allows them to reference columns provided by preceding FROM items. (Without LATERAL, each subquery is evaluated independently and so cannot cross-reference any other FROM item.)

Table functions appearing in FROM can also be preceded by the key word LATERAL, but for functions the key word is optional; the function's arguments can contain references to columns provided by preceding FROM items in any case.

Basic code examples are given there.

More like a correlated subquery

A LATERAL join is more like a correlated subquery, not a plain subquery, in that expressions to the right of a LATERAL join are evaluated once for each row left of it - just like a correlated subquery - while a plain subquery (table expression) is evaluated once only. (The query planner has ways to optimize performance for either, though.)
Related answer with code examples for both side by side, solving the same problem:

• Optimize GROUP BY query to retrieve latest row per user

For returning more than one column, a LATERAL join is typically simpler, cleaner and faster.
Also, remember that the equivalent of a correlated subquery is LEFT JOIN LATERAL ... ON true:

• Call a set-returning function with an array argument multiple times

Things a subquery can't do

There are things that a LATERAL join can do, but a (correlated) subquery cannot (easily). A correlated subquery can only return a single value, not multiple columns and not multiple rows - with the exception of bare function calls (which multiply result rows if they return multiple rows). But even certain set-returning functions are only allowed in the FROM clause. Like unnest() with multiple parameters in Postgres 9.4 or later. The manual:

This is only allowed in the FROM clause;

So this works, but cannot (easily) be replaced with a subquery:

CREATE TABLE tbl (a1 int[], a2 int[]);
SELECT * FROM tbl, unnest(a1, a2) u(elem1, elem2);  -- implicit LATERAL

The comma (,) in the FROM clause is short notation for CROSS JOIN.
LATERAL is assumed automatically for table functions.
About the special case of UNNEST( array_expression [, ... ] ):

• How do you declare a set-returning-function to only be allowed in the FROM clause?

Set-returning functions in the SELECT list

You can also use set-returning functions like unnest() in the SELECT list directly. This used to exhibit surprising behavior with more than one such function in the same SELECT list up to Postgres 9.6. But it has finally been sanitized with Postgres 10 and is a valid alternative now (even if not standard SQL). See:

• What is the expected behaviour for multiple set-returning functions in SELECT clause?

Building on above example:

SELECT *, unnest(a1) AS elem1, unnest(a2) AS elem2
FROM   tbl;

Comparison:

dbfiddle for pg 9.6 here
dbfiddle for pg 10 here

Clarify misinformation

The manual:

For the INNER and OUTER join types, a join condition must be specified, namely exactly one of NATURAL, ON join_condition, or USING (join_column [, ...]). See below for the meaning.
For CROSS JOIN, none of these clauses can appear.

So these two queries are valid (even if not particularly useful):

SELECT *
FROM   tbl t
LEFT   JOIN LATERAL (SELECT * FROM b WHERE b.t_id = t.t_id) t ON TRUE;

SELECT *
FROM   tbl t, LATERAL (SELECT * FROM b WHERE b.t_id = t.t_id) t;

While this one is not:

SELECT *
FROM   tbl t
LEFT   JOIN LATERAL (SELECT * FROM b WHERE b.t_id = t.t_id) t;

That's why Andomar's code example is correct (the CROSS JOIN does not require a join condition) and Attila's is was not.

The rebinding behaviour mentioned in other answers does matter in certain circumstances:

>>> a = ([],[])
>>> a[0].append(1)
>>> a
([1], [])
>>> a[1] += [1]
Traceback (most recent call last):
  File "<interactive input>", line 1, in <module>
TypeError: 'tuple' object does not support item assignment

That's because augmented assignment always rebinds, even if the object was mutated in-place. The rebinding here happens to be a[1] = *mutated list*, which doesn't work for tuples.

In order to export out the VAR variable first the most logical and seems working way is to source the variable:

. ./export.bash

or

source ./export.bash

Now when echoing from main shell it works

 echo $VAR
HELLO, VARABLE

We will now reset VAR

export VAR=""
echo $VAR

Now we will execute a script to source the variable then unset it :

./test-export.sh 
HELLO, VARABLE
--
.

the code: cat test-export.sh

    #!/bin/bash
    # Source env variable
    source ./export.bash

    # echo out the variable in test script
    echo $VAR

    # unset the variable 
    unset VAR
    # echo a few dotted lines
    echo "---"
    # now return VAR which is blank
    echo $VAR

Here is one way

PLEASE NOTE: The exports are limited to the script that execute the exports in your main console - so as far as a cron job I would add it like the console like below... for the command part still questionable: here is how you would run in from your shell:

On your command prompt (so long as the export.bash has multiple echo values)

IFS=$'\n'; for entries in $(./export.bash); do  export $entries;  done; ./v1.sh 
HELLO THERE
HI THERE

cat v1.sh

#!/bin/bash
echo $VAR
echo $VAR1

Now so long as this is for your usage - you could make the variables available for your scripts at any time by doing a bash alias like this:

myvars ./v1.sh
HELLO THERE
HI THERE

echo $VAR

.

add this to your .bashrc

function myvars() { 
    IFS=$'\n'; 
    for entries in $(./export.bash); do  export $entries;  done; 

    "$@"; 

    for entries in $(./export.bash); do variable=$(echo $entries|awk -F"=" '{print $1}'); unset $variable;
done

}

source your bashrc file and you can do like above any time ...

Anyhow back to the rest of it..

This has made it available globally then executed the script..

simply echo it out then run export on the echo !

cat export.bash

#!/bin/bash
echo "VAR=HELLO THERE"

Now within script or your console run:

 export "$(./export.bash)"

Try:

echo $VAR
HELLO THERE

Multiple values so long as you know what you are expecting in another script using above method:

cat export.bash

#!/bin/bash
echo "VAR=HELLO THERE"
echo "VAR1=HI THERE"

cat test-export.sh

#!/bin/bash

IFS=$'\n'
for entries in $(./export.bash); do
   export $entries
done

echo "round 1"
echo $VAR
echo $VAR1

for entries in $(./export.bash); do
     variable=$(echo $entries|awk -F"=" '{print $1}');
     unset $variable
done

echo "round 2"
echo $VAR
echo $VAR1

Now the results

 ./test-export.sh 
round 1
HELLO THERE
HI THERE
round 2


.

and the final final update to auto assign read the VARIABLES:

./test-export.sh 
Round 0 - Export out then find variable name - 
Set current variable to the variable exported then echo its value
$VAR has value of HELLO THERE
$VAR1 has value of HI THERE
round 1 - we know what was exported and we will echo out known variables
HELLO THERE
HI THERE
Round 2 - We will just return the variable names and unset them 
round 3 - Now we get nothing back

The script: cat test-export.sh

#!/bin/bash

IFS=$'\n'
echo "Round 0 - Export out then find variable name - "
echo "Set current variable to the variable exported then echo its value"
for entries in $(./export.bash); do
 variable=$(echo $entries|awk -F"=" '{print $1}');
 export $entries
 eval current_variable=\$$variable
 echo "\$$variable has value of $current_variable"
done


echo "round 1 - we know what was exported and we will echo out known variables"
echo $VAR
echo $VAR1

echo "Round 2 - We will just return the variable names and unset them "
for entries in $(./export.bash); do
 variable=$(echo $entries|awk -F"=" '{print $1}');
 unset $variable
done

echo "round 3 - Now we get nothing back"
echo $VAR
echo $VAR1

Change the name of the .CSS file Load the page and then change the file again in the original name it works for me.

I'm guessing you probably want to bind a "click" event to a number of radio buttons, read the value of the clicked radiobutton and depending on the value, disable/enable a checkbox and or textbox.

function enableInput(class){
    $('.' + class + ':input').attr('disabled', false);
}

function disableInput(class){
    $('.' + class + ':input').attr('disabled', true);
}

$(document).ready(function(){
    $(".changeBoxes").click(function(event){
        var value = $(this).val();
        if(value == 'x'){
            enableInput('foo'); //with class foo
            enableInput('bar'); //with class bar
        }else{
            disableInput('foo'); //with class foo
            disableInput('bar'); //with class bar
        }
    });
});

In addition to John's answer, and reading up on Lodash (which I had hitherto regarded as a "me-too" to Underscore.js), and seeing the performance tests, reading the source-code, and blog posts, the few points which make Lodash much superior to Underscore.js are these:

1. It's not about the speed, as it is about consistency of speed (?)

If you look into Underscore.js's source-code, you'll see in the first few lines that Underscore.js falls-back on the native implementations of many functions. Although in an ideal world, this would have been a better approach, if you look at some of the performance links given in these slides, it is not hard to draw the conclusion that the quality of those 'native implementations' vary a lot browser-to-browser. Firefox is damn fast in some of the functions, and in some Chrome dominates. (I imagine there would be some scenarios where Internet Explorer would dominate too). I believe that it's better to prefer a code whose performance is more consistent across browsers.

Do read the blog post earlier, and instead of believing it for its sake, judge for yourself by running the benchmarks. I am stunned right now, seeing a Lodash performing 100-150% faster than Underscore.js in even simple, native functions such as Array.every in Chrome!

2. The extras in Lodash are also quite useful.
3. As for Xananax's highly upvoted comment suggesting contribution to Underscore.js's code: It's always better to have GOOD competition, not only does it keep innovation going, but also drives you to keep yourself (or your library) in good shape.

Here is a list of differences between Lodash, and it's Underscore.js build is a drop-in replacement for your Underscore.js projects.

I use a similar technique to lazyload images, but can't help but notice that Javascript doesn't access the browser cache on first loading.

My example:

I have a rotating banner on my homepage with 4 images the slider wait 2 seconds, than the javascript loads the next image, waits 2 seconds, etc.

These images have unique urls that change whenever I modify them, so they get caching headers that will cache in the browser for a year.

max-age: 31536000, public

Now when I open Chrome Devtools and make sure de 'Disable cache' option is not active and load the page for the first time (after clearing the cache) all images get fetch and have a 200 status. After a full cycle of all images in the banner the network requests stop and the cached images are used.

Now when I do a regular refresh or go to a subpage and click back, the images that are in the cache seems to be ignored. I would expect to see a grey message "from disk cache" in the Network tab of Chrome devtools. In instead I see the requests pass by every two seconds with a Green status circle instead of gray, I see data being transferred, so it I get the impression the cache is not accessed at all from javascript. It simply fetches the image each time the page gets loaded.

So each request to the homepage triggers 4 requests regardless of the caching policy of the image.

Considering the above together and the new http2 standard most webservers and browsers now support, I think it's better to stop using lazyloading since http2 will load all images nearly simultaneously.

If this is a bug in Chrome Devtools it really surprises my nobody noticed this yet. ;)

If this is true, using lazyloading only increases bandwith usage.

Please correct me if I'm wrong. :)

Instead of

mount -o rw,remount /system/

use

mount -o rw,remount /system

mind the '/' at the end of the command. you ask why this matters? /system/ is the directory under /system while /system is the volume name.

CMD.EXE will not execute internal commands contained inside the string. Only actual files can be launched with that string.

You will need to actually call a batch file to do what you want.

BAT1.bat

start cmd.exe /k bat2.bat

BAT2.bat

cd C:\activiti-5.9\setup
ant demo.start

You may want to create a folder called BAT, and add it's location to your path. So if you create C:\BAT, add C:\BAT\; to the path. The path is located at:

    click -> Start -> right-click Computer -> Properties ->
    click -> Avanced System Settings -> Environment Variables
   select -> Path (From either list. User Variables are specific to 
                   your profile, System Variables are, duh, system-wide.)
    Click -> Edit
Press the -> the [END] or [HOME] key.
     Type -> C:\BAT\;
    Click -> OK -> OK

Now place all your batch files in C:\BAT and they will be found, regardless of the current directory.

Try:

<table border="1">
  <tr>
    <td>
      <table border="">
      ...
      </table>
    </td>
  </tr>
</table>

System.IO.Compression is now available as a nuget package maintained by Microsoft.

To use ZipFile you need to download System.IO.Compression.ZipFile nuget package.

CSS3 has a pseudo-class called :not()

input:not([type='checkbox']) {    
    visibility: hidden;
}

<p>If <code>:not()</code> is supported, you'll only see the checkbox.</p>
                                      
<ul>
  <li>text: (<input type="text">)</li>  
  <li>password (<input type="password">)</li>       
  <li>checkbox (<input type="checkbox">)</li> 
 </ul>

Multiple selectors

As Vincent mentioned, it's possible to string multiple :not()s together:

input:not([type='checkbox']):not([type='submit'])

CSS4, which is supported in many of the latest browser releases, allows multiple selectors in a :not()

input:not([type='checkbox'],[type='submit'])

Legacy support

All modern browsers support the CSS3 syntax. At the time this question was asked, we needed a fall-back for IE7 and IE8. One option was to use a polyfill like IE9.js. Another was to exploit the cascade in CSS:

input {
   // styles for most inputs
}   

input[type=checkbox] {
  // revert back to the original style
} 

input.checkbox {
  // for completeness, this would have worked even in IE3!
} 

I like a @GLee approach and using it with fragment like below.

@Override
public void onBackPressed() {
    if(isTaskRoot()) {
        new ExitDialogFragment().show(getSupportFragmentManager(), null);
    } else {
        super.onBackPressed();
    }
}

Dialog using Fragment:

public class ExitDialogFragment extends DialogFragment {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        return new AlertDialog.Builder(getActivity())
            .setTitle(R.string.exit_question)
            .setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    getActivity().finish();
                }
            })
            .setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    getDialog().cancel();
                }
            })
            .create();
    }
}

Best:

 std::string subCondition;

This creates an empty string.

This:

std::string myStr = "";

does a copy initialization - creates a temporary string from "", and then uses the copy constructor to create myStr.

Bonus:

std::string myStr("");

does a direct initialization and uses the string(const char*) constructor.

To check if a string is empty, just use empty().

You could use a project post-build event to write a text file to your target directory with the current datetime. You could then read the value at run-time. It's a little hacky, but it should work.

You can use private as well and you can call private methods with reflection. If you're using Visual Studio Team Suite it has some nice functionality that will generate a proxy to call your private methods for you. Here's a code project article that demonstrates how you can do the work yourself to unit test private and protected methods:

http://www.codeproject.com/KB/cs/testnonpublicmembers.aspx

In terms of which access modifier you should use, my general rule of thumb is start with private and escalate as needed. That way you will expose as little of the internal details of your class as are truly needed and it helps keep the implementation details hidden, as they should be.

It appears the default setting for Adobe Reader X is for the toolbars not to be shown by default unless they are explicitly turned on by the user. And even when I turn them back on during a session, they don't show up automatically next time. As such, I suspect you have a preference set contrary to the default.

The state you desire, with the top and left toolbars not shown, is called "Read Mode". If you right-click on the document itself, and then click "Page Display Preferences" in the context menu that is shown, you'll be presented with the Adobe Reader Preferences dialog. (This is the same dialog you can access by opening the Adobe Reader application, and selecting "Preferences" from the "Edit" menu.) In the list shown in the left-hand column of the Preferences dialog, select "Internet". Finally, on the right, ensure that you have the "Display in Read Mode by default" box checked:

You can also turn off the toolbars temporarily by clicking the button at the right of the top toolbar that depicts arrows pointing to opposing corners:

Finally, if you have "Display in Read Mode by default" turned off, but want to instruct the page you're loading not to display the toolbars (i.e., override the user's current preferences), you can append the following to the URL:

#toolbar=0&navpanes=0

So, for example, the following code will disable both the top toolbar (called "toolbar") and the left-hand toolbar (called "navpane"). However, if the user knows the keyboard combination (F8, and perhaps other methods as well), they will still be able to turn them back on.

string url = @"http://www.domain.com/file.pdf#toolbar=0&navpanes=0";
this._WebBrowser.Navigate(url);

You can read more about the parameters that are available for customizing the way PDF files open here on Adobe's developer website.

Just create a new MFC C++ app. It's built in, pretty easy, and thousands of examples exist in the world...

Plus, you can design your dialog box right in Visual Studio, give them variable names, and 90% of the code is generated for you.

I would suggest querying the sys views. something similar to

SELECT * 
FROM 
   sys.dm_exec_sessions s
   LEFT  JOIN sys.dm_exec_connections c
        ON  s.session_id = c.session_id
   LEFT JOIN sys.dm_db_task_space_usage tsu
        ON  tsu.session_id = s.session_id
   LEFT JOIN sys.dm_os_tasks t
        ON  t.session_id = tsu.session_id
        AND t.request_id = tsu.request_id
   LEFT JOIN sys.dm_exec_requests r
        ON  r.session_id = tsu.session_id
        AND r.request_id = tsu.request_id
   OUTER APPLY sys.dm_exec_sql_text(r.sql_handle) TSQL

This way you can get a TotalPagesAllocated which can help you figure out the spid that is taking all the server resources. There has lots of times when I can't even bring up activity monitor and use these sys views to see what's going on.

I would recommend you reading the following article. I got this reference from here.

Use this code so that the dialog activity won't be closed when the user touches outside the dialog box:

this.setFinishOnTouchOutside(false);

requires API level 11

git log --grep="Build 0051"

Just pass with sshpass -p "your password" at the beginning of your scp command

sshpass -p "your password" scp ./abc.txt hostname/abc.txt

Please try this:

gradlew -DskipTests=true build

Don't define variables in headers. Put declarations in header and definitions in one of the .c files.

In config.h

extern const char *names[];

In some .c file:

const char *names[] =
    {
        "brian", "stefan", "steve"
    };

If you put a definition of a global variable in a header file, then this definition will go to every .c file that includes this header, and you will get multiple definition error because a varible may be declared multiple times but can be defined only once.

I usually use the .ToString() method on exceptions to present the full exception information (including the inner stack trace) in text:

catch (MyCustomException ex)
{
    Debug.WriteLine(ex.ToString());
}

Sample output:

ConsoleApplication1.MyCustomException: some message .... ---> System.Exception: Oh noes!
   at ConsoleApplication1.SomeObject.OtherMethod() in C:\ConsoleApplication1\SomeObject.cs:line 24
   at ConsoleApplication1.SomeObject..ctor() in C:\ConsoleApplication1\SomeObject.cs:line 14
   --- End of inner exception stack trace ---
   at ConsoleApplication1.SomeObject..ctor() in C:\ConsoleApplication1\SomeObject.cs:line 18
   at ConsoleApplication1.Program.DoSomething() in C:\ConsoleApplication1\Program.cs:line 23
   at ConsoleApplication1.Program.Main(String[] args) in C:\ConsoleApplication1\Program.cs:line 13

xxd -p file

Or if you want it all on a single line:

xxd -p file | tr -d '\n'

Don't make data frames. Keep the list, name its elements but do not attach it.

The biggest reason for this is that if you make variables on the go, almost always you will later on have to iterate through each one of them to perform something useful. There you will again be forced to iterate through each one of the names that you have created on the fly.

It is far easier to name the elements of the list and iterate through the names.

As far as attach is concerned, its really bad programming practice in R and can lead to a lot of trouble if you are not careful.

Anyone could potentially use this command to rename a field from the collection (By not using any _id):

dbName.collectionName.update({}, {$rename:{"oldFieldName":"newFieldName"}}, false, true);

How about checking this before doing the redirect:

if (!Response.IsRequestBeingRedirected)
{
   //do the redirect
}

window.location adds an item to your history in that you can (or should be able to) click "Back" and go back to the current page.

window.location.replace replaces the current history item so you can't go back to it.

See window.location:

assign(url): Load the document at the provided URL.

replace(url):Replace the current document with the one at the provided URL. The difference from the assign() method is that after using replace() the current page will not be saved in session history, meaning the user won't be able to use the Back button to navigate to it.

Oh and generally speaking:

window.location.href = url;

is favoured over:

window.location = url;

It might be worth mentioning that you can also create a .dockerignore file, to exclude the files that you don't want to copy:

https://docs.docker.com/engine/reference/builder/#dockerignore-file

Before the docker CLI sends the context to the docker daemon, it looks for a file named .dockerignore in the root directory of the context. If this file exists, the CLI modifies the context to exclude files and directories that match patterns in it. This helps to avoid unnecessarily sending large or sensitive files and directories to the daemon and potentially adding them to images using ADD or COPY.

Use svn revert --recursive folder_name

Warning

svn revert is inherently dangerous, since its entire purpose is to throw away data — namely, your uncommitted changes. Once you've reverted, Subversion provides no way to get back those uncommitted changes.

http://svnbook.red-bean.com/en/1.7/svn.ref.svn.c.revert.html

If it's just for viewing data, I use simple foreach or even aspRepeater. For editing I build specialized views and actions. Didn't like webforms GridView inline edit capabilities anyway, this is kinda much clearer and better - one view for viewing and another for edit/new.

Just use final class.

If you want to be able to add other values use an abstract class.

It doesn't make much sense using an interface, an interface is supposed to specify a contract. You just want to declare some constant values.

Using simple autofocus HTML5 attribute works for 'on load' scenario

 <input autofocus placeholder="enter text" [(ngModel)]="test">

or

<button autofocus (click)="submit()">Submit</button>

To install Sublime Text 3 run:

brew install --cask sublime-text

reference: https://formulae.brew.sh/cask/sublime-text

That's rather hard to say - in order to really find out which one works better, you'd need to actually profile the execution times.

As a general rule of thumb, I think if you have indices on your foreign key columns, and if you're using only (or mostly) INNER JOIN conditions, then the JOIN will be slightly faster.

But as soon as you start using OUTER JOIN, or if you're lacking foreign key indexes, the IN might be quicker.

TempData

Basically it's like a DataReader, once read, data will be lost.

Check this Video

Example

public class HomeController : Controller
{
    public ActionResult Index()
    {
        ViewBag.Message = "Welcome to ASP.NET MVC!";
        TempData["T"] = "T";
        return RedirectToAction("About");
    }

    public ActionResult About()
    {
        return RedirectToAction("Test1");
    }

    public ActionResult Test1()
    {
        String str = TempData["T"]; //Output - T
        return View();
    }
}

If you pay attention to the above code, RedirectToAction has no impact over the TempData until TempData is read. So, once TempData is read, values will be lost.

How can i keep the TempData after reading?

Check the output in Action Method Test 1 and Test 2

public class HomeController : Controller
{
    public ActionResult Index()
    {
        ViewBag.Message = "Welcome to ASP.NET MVC!";
        TempData["T"] = "T";
        return RedirectToAction("About");
    }

    public ActionResult About()
    {
        return RedirectToAction("Test1");
    }

    public ActionResult Test1()
    {
        string Str = Convert.ToString(TempData["T"]);
        TempData.Keep(); // Keep TempData
        return RedirectToAction("Test2");
    }

    public ActionResult Test2()
    {
        string Str = Convert.ToString(TempData["T"]); //OutPut - T
        return View();
    }
}

If you pay attention to the above code, data is not lost after RedirectToAction as well as after Reading the Data and the reason is, We are using TempData.Keep(). is that

In this way you can make it persist as long as you wish in other controllers also.

ViewBag/ViewData

The Data will persist to the corresponding View

You are confusing regular expression with shell globbing. If you want to use regular expression to match file names you could do:

$ ls | egrep '.+\..+'

The accepted answer wasn't working for me when trying to parse the registry for uninstall strings, and execute them. Turns out I didn't need the call to Invoke-Expression after all.

I finally came across this nice template for seeing how to execute uninstall strings:

$path = 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall'
$app = 'MyApp'
$apps= @{}
Get-ChildItem $path | 
    Where-Object -FilterScript {$_.getvalue('DisplayName') -like $app} | 
    ForEach-Object -process {$apps.Set_Item(
        $_.getvalue('UninstallString'),
        $_.getvalue('DisplayName'))
    }

foreach ($uninstall_string in $apps.GetEnumerator()) {
    $uninstall_app, $uninstall_arg = $uninstall_string.name.split(' ')
    & $uninstall_app $uninstall_arg
}

This works for me, namely because $app is an in house application that I know will only have two arguments. For more complex uninstall strings you may want to use the join operator. Also, I just used a hash-map, but really, you'd probably want to use an array.

Also, if you do have multiple versions of the same application installed, this uninstaller will cycle through them all at once, which confuses MsiExec.exe, so there's that too.

function sample() {
    alert("This is sample function");
}

$(function() {
    $("#button").click(function() {
        setTimeout(sample, 2000);
    });

});

jsFiddle.

If you want to encapsulate sample() there, wrap the whole thing in a self invoking function (function() { ... })().

I just found this out by trying to see if my event was attached....

if you do :

item.onclick

it will return "null"

but if you do:

item.hasOwnProperty('onclick')

then it is "TRUE"

so I think that when you use "addEventListener" to add event handlers, the only way to access it is through "hasOwnProperty". I wish I knew why or how but alas, after researching, I haven't found an explanation.

The right answer is

Decoupled the build-specific components of the Android SDK from the platform-tools component, so that the build tools can be updated independently of the integrated development environment (IDE) components.

If I feel that useful information is being imparted, why shouldn't I put it right there where it's available?

Then who cares what anybody else thinks? If you find it useful, then use the notation.

Change the checkboxes so that the name includes the index inside the brackets:

<input type="checkbox" class="checkbox_veh" id="checkbox_addveh<?php echo $i; ?>" <?php if ($vehicle_feature[$i]->check) echo "checked"; ?> name="feature[<?php echo $i; ?>]" value="<?php echo $vehicle_feature[$i]->id; ?>"> 

The checkboxes that aren't checked are never submitted. The boxes that are checked get submitted, but they get numbered consecutively from 0, and won't have the same indexes as the other corresponding input fields.

A good example could be next: for instance you have a set of Loggers and you allows user to specify type to be used in runtime via configuration file.

Then:

string rawLoggerType = configurationService.GetLoggerType();
Type loggerType = Type.GetType(rawLoggerType);
ILogger logger = Activator.CreateInstance(loggerType.GetType()) as ILogger;

OR another case is when you have a common entities factory, which creates entity, and is also responsible on initialization of an entity by data received from DB:

(pseudocode)

public TEntity CreateEntityFromDataRow<TEntity>(DataRow row)
 where TEntity : IDbEntity, class
{
   MethodInfo methodInfo = typeof(T).GetMethod("BuildFromDataRow");
   TEntity instance = Activator.CreateInstance(typeof(TEntity)) as TEntity;
   return methodInfo.Invoke(instance, new object[] { row } ) as TEntity;
}

$(".field-group_name").each(function() {
        console.log($(this).text());
    });

Byte is not a standard type in C or C++. Try char, which is usually and at least 8 bits long.

Here is an example with CSS and inline style attributes:

td _x000D_
{_x000D_
    height: 50px; _x000D_
    width: 50px;_x000D_
}_x000D_
_x000D_
#cssTable td _x000D_
{_x000D_
    text-align: center; _x000D_
    vertical-align: middle;_x000D_
}

<table border="1">_x000D_
    <tr>_x000D_
        <td style="text-align: center; vertical-align: middle;">Text</td>_x000D_
        <td style="text-align: center; vertical-align: middle;">Text</td>_x000D_
    </tr>_x000D_
</table>_x000D_
_x000D_
<table border="1" id="cssTable">_x000D_
    <tr>_x000D_
        <td>Text</td>_x000D_
        <td>Text</td>_x000D_
    </tr>_x000D_
</table>

EDIT: The valign attribute is deprecated in HTML5 and should not be used.

I know the OP was asking about doing the export from the command line, but just in case this is helpful to anyone else out there...

You could just let Eclipse (plus one of the plugins discussed here) do the work for you.

Obviously, downloading Eclipse just for doing a single export is overkill, but if you are already using it for development, you can also do an svn export simply from your IDE's context menu when browsing an SVN repository.

Advantages:

• easier for those not so familiar with using SVN at the command-line level (but you can learn about what happens at the command-line level by looking at the SVN console with a range of commands)
• you'd already have your SVN details set up and wouldn't have to worry about authenticating, etc.
• you don't have to worry about mistyping the URL, or remembering the order of parameters
• you can specify in a dialog which directory you'd like to export to
• you can specify in a dialog whether you'd like to export from TRUNK/HEAD or use a specific revision

Just run the command:

php artisan migrate:refresh --seed

python -c "exec(open('main.py').read())"

sometimes will b usable this line on any layout or components.

 android:background="?attr/selectableItemBackground"

Like as.

 <RelativeLayout
                android:id="@+id/relative_ticket_checkin"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_weight="1"
                android:background="?attr/selectableItemBackground">

In my opinion, jQuery's animate is a bit overused, compared to the CSS3 transition, which performs such animation on any 2D or 3D property. Also I'm afraid, that leaving it to the browser and by forgetting the layer called JavaScript could lead to spare CPU juice - specially, when you wish to blast with the animations. Thus, I like to have animations where the style definitions are, since you define functionality with JavaScript. The more presentation you inject into JavaScript, the more problems you'll face later on.

All you have to do is to use addClass to the element you wish to animate, where you set a class that has CSS transition properties. You just "activate" the animation, which stays implemented on the pure presentation layer.

.js

// with jQuery
$("#element").addClass("Animate");

// without jQuery library
document.getElementById("element").className += "Animate";

One could easly remove a class with jQuery, or remove a class without library.

.css

#element{
    color      : white;
}

#element.Animate{
    transition        : .4s linear;
    color             : red;
    /** 
     * Not that ugly as the JavaScript approach.
     * Easy to maintain, the most portable solution.
     */
    -webkit-transform : rotate(90deg);
}

.html

<span id="element">
    Text
</span>

This is a fast and convenient solution for most use cases.

I also use this when I want to implement a different styling (alternative CSS properties), and wish to change the style on-the-fly with a global .5s animation. I add a new class to the BODY, while having alternative CSS in a form like this:

.js

$("BODY").addClass("Alternative");

.css

BODY.Alternative #element{
    color      : blue;
    transition : .5s linear;
}

This way you can apply different styling with animations, without loading different CSS files. You only involve JavaScript to set a class.

This is stupid but for future reference. I did put all my code in:

$(document).ready(function () {
    //your jQuery function
});

But still it wasn't working and it was returning undefined value. I check my HTML DOM

<input id="username" placeholder="Username"></input>

and I realised that I was referencing it wrong in jQuery:

var user_name = $('#user_name').val();

Making it:

var user_name = $('#username').val();

solved my problem.

So it's always better to check your previous code.

As to the CSS suggestion:

#myCanvas { 
 width: 100%;
 height: 100%;
}

By the standard, CSS does not size the canvas coordinate system, it scales the content. In Chrome, the CSS mentioned will scale the canvas up or down to fit the browser's layout. In the typical case where the coordinate system is smaller than the browser's dimensions in pixels, this effectively lowers the resolution of your drawing. It most likely results in non-proportional drawing as well.

Use java.lang.String.format(String,Object...) like this:

String.format("%05d", yournumber);

for zero-padding with a length of 5. For hexadecimal output replace the d with an x as in "%05x".

The full formatting options are documented as part of java.util.Formatter.

Straight out of the documentation for collections.OrderedDict:

>>> # dictionary sorted by value
>>> OrderedDict(sorted(d.items(), key=lambda t: t[1]))
OrderedDict([('pear', 1), ('orange', 2), ('banana', 3), ('apple', 4)])

Adapted to the example in the original post:

>>> l=[2,3,1,4,5]
>>> OrderedDict(sorted(enumerate(l), key=lambda x: x[1])).keys()
[2, 0, 1, 3, 4]

See http://docs.python.org/library/collections.html#collections.OrderedDict for details.

You can do it by running with following command.

php -S localhost:8888

To Save your bitmap in sdcard use the following code

Store Image

private void storeImage(Bitmap image) {
    File pictureFile = getOutputMediaFile();
    if (pictureFile == null) {
        Log.d(TAG,
                "Error creating media file, check storage permissions: ");// e.getMessage());
        return;
    } 
    try {
        FileOutputStream fos = new FileOutputStream(pictureFile);
        image.compress(Bitmap.CompressFormat.PNG, 90, fos);
        fos.close();
    } catch (FileNotFoundException e) {
        Log.d(TAG, "File not found: " + e.getMessage());
    } catch (IOException e) {
        Log.d(TAG, "Error accessing file: " + e.getMessage());
    }  
}

To Get the Path for Image Storage

/** Create a File for saving an image or video */
private  File getOutputMediaFile(){
    // To be safe, you should check that the SDCard is mounted
    // using Environment.getExternalStorageState() before doing this. 
    File mediaStorageDir = new File(Environment.getExternalStorageDirectory()
            + "/Android/data/"
            + getApplicationContext().getPackageName()
            + "/Files"); 

    // This location works best if you want the created images to be shared
    // between applications and persist after your app has been uninstalled.

    // Create the storage directory if it does not exist
    if (! mediaStorageDir.exists()){
        if (! mediaStorageDir.mkdirs()){
            return null;
        }
    } 
    // Create a media file name
    String timeStamp = new SimpleDateFormat("ddMMyyyy_HHmm").format(new Date());
    File mediaFile;
        String mImageName="MI_"+ timeStamp +".jpg";
        mediaFile = new File(mediaStorageDir.getPath() + File.separator + mImageName);  
    return mediaFile;
} 

EDIT From Your comments i have edited the onclick view in this the button1 and button2 functions will be executed separately.

public onClick(View v){

switch(v.getId()){
case R.id.button1:
//Your button 1 function
break;
case R.id. button2:
//Your button 2 function
break;
} 
}

The await inside your asynchronous method is trying to come back to the UI thread.

Since the UI thread is busy waiting for the entire task to complete, you have a deadlock.

Moving the async call to Task.Run() solves the issue.
Because the async call is now running on a thread pool thread, it doesn't try to come back to the UI thread, and everything therefore works.

Alternatively, you could call StartAsTask().ConfigureAwait(false) before awaiting the inner operation to make it come back to the thread pool rather than the UI thread, avoiding the deadlock entirely.

I did test your code and the only problem I could see was the lack of permission given to the directory you try to write the file in to.

Give "write" permission to the directory you need to put the file. In your case it is the current directory.

Use "chmod" in linux.

Add "Everyone" with "write" enabled to the security tab of the directory if you are in Windows.

So the Enum has a __members__ dict. The solution that @ozgur proposed is really the best, but you can do this, which does the same thing, with more work

[color.value for color_name, color in Color.__members__.items()]

The __members__ dictionary could come in handy if you wanted to insert stuff dynamically in it... in some crazy situation.

[EDIT] Apparently __members__ is not a dictionary, but a map proxy. Which means you can't easily add items to it.

You can however do weird stuff like MyEnum.__dict__['_member_map_']['new_key'] = 'new_value', and then you can use the new key like MyEnum.new_key.... but this is just an implementation detail, and should not be played with. Black magic is payed for with huge maintenance costs.

According to the documentation, timestamp is a synonym for rowversion - it's automatically generated and guaranteed¹ to be unique. datetime isn't - it's just a data type which handles dates and times, and can be client-specified on insert etc.

¹ Assuming you use it properly, of course. See comments.

The REFERER is sent by the client's browser as part of the HTTP protocol, and is therefore unreliable indeed. It might not be there, it might be forged, you just can't trust it if it's for security reasons.

If you want to verify if a request is coming from your site, well you can't, but you can verify the user has been to your site and/or is authenticated. Cookies are sent in AJAX requests so you can rely on that.

You can obtain this information and much, much more by querying the Information Schema views.

This sample query:

SELECT *
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = N'Customers'

Can be made over all these DB objects:

• CHECK_CONSTRAINTS
• COLUMN_DOMAIN_USAGE
• COLUMN_PRIVILEGES
• COLUMNS
• CONSTRAINT_COLUMN_USAGE
• CONSTRAINT_TABLE_USAGE
• DOMAIN_CONSTRAINTS
• DOMAINS
• KEY_COLUMN_USAGE
• PARAMETERS
• REFERENTIAL_CONSTRAINTS
• ROUTINES
• ROUTINE_COLUMNS
• SCHEMATA
• TABLE_CONSTRAINTS
• TABLE_PRIVILEGES
• TABLES
• VIEW_COLUMN_USAGE
• VIEW_TABLE_USAGE
• VIEWS

Use £. I had the same problem and solved it using jQuery:

$(this).text('£');

• If you try this and it does not work, just change the jQuery methods,

$(this).html('£');

• This always work in all contexts...

Use #pragma for organization

You can use:

#pragma mark Foo

... as a way to organize methods in your source files. When browsing symbols via the pop up menu, whatever you place in Foo will appear bold in the list.

To display a separator (i.e. horizontal line), use:

#pragma mark -

It's very useful, especially for grouping together delegate methods or other groups of methods.

This is an array of the command line switches pass to the program. E.g. if you start the program with the command "myapp.exe -c -d" then string[] args[] will contain the strings "-c" and "-d".

No need to create a GD resource, as someone else suggested.

$input = 'http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com';
$output = 'google.com.jpg';
file_put_contents($output, file_get_contents($input));

Note: this solution only works if you're setup to allow fopen access to URLs. If the solution above doesn't work, you'll have to use cURL.

If you want to send emails simultaneously to all the admins, you can do something like this:

In your .env file add all the emails as comma separated values:

[email protected],[email protected],[email protected]

so when you going to send the email just do this (yes! the 'to' method of message builder instance accepts an array):

So,

$to = explode(',', env('ADMIN_EMAILS'));

and...

$message->to($to);

will now send the mail to all the admins.

I think that once you've imported it, the behaviour is the same (in the place your variable will be used outside source file).

The only difference would be if you try to reassign it before the end of this very file.

You may create a new list with an input of a previous list like so:

List one = new ArrayList()
//... add data, sort, etc
List two = new ArrayList(one);

This will allow you to modify the order or what elemtents are contained independent of the first list.

Keep in mind that the two lists will contain the same objects though, so if you modify an object in List two, the same object will be modified in list one.

example:

MyObject value1 = one.get(0);
MyObject value2 = two.get(0);
value1 == value2 //true
value1.setName("hello");
value2.getName(); //returns "hello"

Edit

To avoid this you need a deep copy of each element in the list like so:

List<Torero> one = new ArrayList<Torero>();
//add elements

List<Torero> two = new Arraylist<Torero>();
for(Torero t : one){
    Torero copy = deepCopy(t);
    two.add(copy);
}

with copy like the following:

public Torero deepCopy(Torero input){
    Torero copy = new Torero();
    copy.setValue(input.getValue());//.. copy primitives, deep copy objects again

    return copy;
}

You can use the :last-of-type to catch last column of your table.

<style>
.table > tbody > tr > td:last-of-type {
    /* Give your style Here; */
}
</style>

Like Pekka said, it should work this way. I can't reproduce the problem with this self-contained example:

<?php
    $pdo = new PDO('mysql:host=localhost;dbname=test;charset=utf8', 'localonly', 'localonly');
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);

    $pdo->exec('
        CREATE TEMPORARY TABLE soFoo (
            id int auto_increment,
            first int,
            last int,
            whenadded DATETIME,
            primary key(id)
        )
    ');
    $pdo->exec('INSERT INTO soFoo (first,last,whenadded) VALUES (0,1,Now())');
    $pdo->exec('INSERT INTO soFoo (first,last,whenadded) VALUES (0,2,Now())');
    $pdo->exec('INSERT INTO soFoo (first,last,whenadded) VALUES (0,3,Now())');

    foreach( $pdo->query('SELECT * FROM soFoo', PDO::FETCH_ASSOC) as $row ) {
        echo join(' | ', $row), "\n";
    }

Which (currently) prints

1 | 0 | 1 | 2012-03-23 16:00:18
2 | 0 | 2 | 2012-03-23 16:00:18
3 | 0 | 3 | 2012-03-23 16:00:18

And here's (almost) the same script using a TIMESTAMP field and DEFAULT CURRENT_TIMESTAMP:

<?php
    $pdo = new PDO('mysql:host=localhost;dbname=test;charset=utf8', 'localonly', 'localonly');
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);

    $pdo->exec('
        CREATE TEMPORARY TABLE soFoo (
            id int auto_increment,
            first int,
            last int,
            whenadded TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
            primary key(id)
        )
    ');
    $pdo->exec('INSERT INTO soFoo (first,last) VALUES (0,1)');
    $pdo->exec('INSERT INTO soFoo (first,last) VALUES (0,2)');
    sleep(1);
    $pdo->exec('INSERT INTO soFoo (first,last) VALUES (0,3)');

    foreach( $pdo->query('SELECT * FROM soFoo', PDO::FETCH_ASSOC) as $row ) {
        echo join(' | ', $row), "\n";
    }

Conveniently, the timestamp is converted to the same datetime string representation as in the first example - at least with my PHP/PDO/mysqlnd version.

Use this to implement mask:

https://rawgit.com/RobinHerbots/jquery.inputmask/3.x/dist/jquery.inputmask.bundle.js

<input id="phn-number" class="ant-input" type="text" placeholder="(XXX) XXX-XXXX" data-inputmask-mask="(999) 999-9999">


jQuery( '#phn-number[data-inputmask-mask]' ).inputmask();

For own property :

var loan = { amount: 150 };
if(Object.prototype.hasOwnProperty.call(loan, "amount")) 
{ 
   //will execute
}

Note: using Object.prototype.hasOwnProperty is better than loan.hasOwnProperty(..), in case a custom hasOwnProperty is defined in the prototype chain (which is not the case here), like

var foo = {
      hasOwnProperty: function() {
        return false;
      },
      bar: 'Here be dragons'
    };

// https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/hasOwnProperty

To include inherited properties in the finding use the in operator: (but you must place an object at the right side of 'in', primitive values will throw error, e.g. 'length' in 'home' will throw error, but 'length' in new String('home') won't)

const yoshi = { skulk: true };
const hattori = { sneak: true };
const kuma = { creep: true };
if ("skulk" in yoshi) 
    console.log("Yoshi can skulk");

if (!("sneak" in yoshi)) 
    console.log("Yoshi cannot sneak");

if (!("creep" in yoshi)) 
    console.log("Yoshi cannot creep");

Object.setPrototypeOf(yoshi, hattori);

if ("sneak" in yoshi)
    console.log("Yoshi can now sneak");
if (!("creep" in hattori))
    console.log("Hattori cannot creep");

Object.setPrototypeOf(hattori, kuma);

if ("creep" in hattori)
    console.log("Hattori can now creep");
if ("creep" in yoshi)
    console.log("Yoshi can also creep");

// https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/in

Note: One may be tempted to use typeof and [ ] property accessor as the following code which doesn't work always ...

var loan = { amount: 150 };

loan.installment = undefined;

if("installment" in loan) // correct
{
    // will execute
}

if(typeof loan["installment"] !== "undefined") // incorrect
{
    // will not execute
}

Faced the same problem. Probably it could be a solution:

<select id="select-1">
    <option>One</option>
    <option>Two</option>
    <option>Three</option>
</select>
<label for="select-1"></label>

#select-1 {
    ...
}

#select-1 + label:after {
    ...
}

Please see my project of the cross-browser filter of value of the text input element on your web page using JavaScript language: Input Key Filter . You can filter the value as an integer number, a float number, or write a custom filter, such as a phone number filter. See an example of code of input an integer number:

Like others have mentioned, a functor is an object that acts like a function, i.e. it overloads the function call operator.

Functors are commonly used in STL algorithms. They are useful because they can hold state before and between function calls, like a closure in functional languages. For example, you could define a MultiplyBy functor that multiplies its argument by a specified amount:

class MultiplyBy {
private:
    int factor;

public:
    MultiplyBy(int x) : factor(x) {
    }

    int operator () (int other) const {
        return factor * other;
    }
};

Then you could pass a MultiplyBy object to an algorithm like std::transform:

int array[5] = {1, 2, 3, 4, 5};
std::transform(array, array + 5, array, MultiplyBy(3));
// Now, array is {3, 6, 9, 12, 15}

Another advantage of a functor over a pointer to a function is that the call can be inlined in more cases. If you passed a function pointer to transform, unless that call got inlined and the compiler knows that you always pass the same function to it, it can't inline the call through the pointer.

It sounds like you want a StackPanel where the final element uses up all the remaining space. But why not use a DockPanel? Decorate the other elements in the DockPanel with DockPanel.Dock="Top", and then your help control can fill the remaining space.

XAML:

<DockPanel Width="200" Height="200" Background="PowderBlue">
    <TextBlock DockPanel.Dock="Top">Something</TextBlock>
    <TextBlock DockPanel.Dock="Top">Something else</TextBlock>
    <DockPanel
        HorizontalAlignment="Stretch" 
        VerticalAlignment="Stretch" 
        Height="Auto" 
        Margin="10">

      <GroupBox 
        DockPanel.Dock="Right" 
        Header="Help" 
        Width="100" 
        Background="Beige" 
        VerticalAlignment="Stretch" 
        VerticalContentAlignment="Stretch" 
        Height="Auto">
        <TextBlock Text="This is the help that is available on the news screen." 
                   TextWrapping="Wrap" />
     </GroupBox>

      <StackPanel DockPanel.Dock="Left" Margin="10" 
           Width="Auto" HorizontalAlignment="Stretch">
          <TextBlock Text="Here is the news that should wrap around." 
                     TextWrapping="Wrap"/>
      </StackPanel>
    </DockPanel>
</DockPanel>

If you are on a platform without DockPanel available (e.g. WindowsStore), you can create the same effect with a grid. Here's the above example accomplished using grids instead:

<Grid Width="200" Height="200" Background="PowderBlue">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>
    <StackPanel Grid.Row="0">
        <TextBlock>Something</TextBlock>
        <TextBlock>Something else</TextBlock>
    </StackPanel>
    <Grid Height="Auto" Grid.Row="1" Margin="10">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*"/>
            <ColumnDefinition Width="100"/>
        </Grid.ColumnDefinitions>
        <GroupBox
            Width="100"
            Height="Auto"
            Grid.Column="1"
            Background="Beige"
            Header="Help">
            <TextBlock Text="This is the help that is available on the news screen." 
              TextWrapping="Wrap"/>
        </GroupBox>
        <StackPanel Width="Auto" Margin="10" DockPanel.Dock="Left">
            <TextBlock Text="Here is the news that should wrap around." 
              TextWrapping="Wrap"/>
        </StackPanel>
    </Grid>
</Grid>

The callback to $.each() is passed the property name and the value, in that order. You're therefore trying to iterate over the property names in the inner call to $.each(). I think you want:

$.each(myMap, function (i, val) {
  $.each(val, function(innerKey, innerValue) {
    // ...
  });
});

In the inner loop, given an object like your map, the values are arrays. That's OK, but note that the "innerKey" values will all be numbers.

edit — Now once that's straightened out, here's the next problem:

    setTimeout(function () {

      // ...

    }, i * 6000);

The first time through that loop, "i" will be the string "partnr1". Thus, that multiplication attempt will result in a NaN. You can keep an external counter to keep track of the property count of the outer map:

var pcount = 1;
$.each(myMap, function(i, val) {
  $.each(val, function(innerKey, innerValue) {
    setTimeout(function() {
      // ...
    }, pcount++ * 6000);
  });
});

var 
         /**
         * Parses time in milliseconds to time structure
         * @param {Number} ms
         * @returns {Object} timeStruct
         * @return {Integer} timeStruct.d days
         * @return  {Integer} timeStruct.h hours
         * @return  {Integer} timeStruct.m minutes
         * @return  {Integer} timeStruct.s seconds
         */
        millisecToTimeStruct = function (ms) {
            var d, h, m, s;
            if (isNaN(ms)) {
                return {};
            }
            d = ms / (1000 * 60 * 60 * 24);
            h = (d - ~~d) * 24;
            m = (h - ~~h) * 60;
            s = (m - ~~m) * 60;
            return {d: ~~d, h: ~~h, m: ~~m, s: ~~s};
        },

        toFormattedStr = function(tStruct){
           var res = '';
           if (typeof tStruct === 'object'){
               res += tStruct.m + ' min. ' + tStruct.s + ' sec.';
           }
           return res;
        };

// client code:
var
        ms = new Date().getTime(),
        timeStruct = millisecToTimeStruct(ms),
        formattedString = toFormattedStr(timeStruct);
alert(formattedString);

Late to the story but I think some details are overlooked?

if you use

if (uemail !== undefined) {
  //some function
}

You are, technically, comparing variable uemail with variable undefined and, as the latter is not instantiated, it will give both type and value of 'undefined' purely by default, hence the comparison returns true. But it overlooks the potential that a variable by the name of undefined may actually exist -however unlikely- and would therefore then not be of type undefined. In that case, the comparison will return false.

To be correct one would have to declare a constant of type undefined for example:

const _undefined: undefined

and then test by:

if (uemail === _undefined) {
  //some function
}

This test will return true as uemail now equals both value & type of _undefined as _undefined is now properly declared to be of type undefined.

Another way would be

if (typeof(uemail) === 'undefined') {
  //some function
}

In which case the boolean return is based on comparing the two strings on either end of the comparison. This is, from a technical point of view, NOT testing for undefined, although it achieves the same result.

You may try the Object Browser in Visual Studio.

Select Edit Custom Component Set. From there, you can choose from a variety of .NET, COM or project libraries or just import external dlls via Browse.

In case of writing in python3

>>> a = u'bats\u00E0'
>>> print a
batsà
>>> f = open("/tmp/test", "w")
>>> f.write(a)
>>> f.close()
>>> data = open("/tmp/test").read()
>>> data
'batsà'

In case of writing in python2:

>>> a = u'bats\u00E0'
>>> f = open("/tmp/test", "w")
>>> f.write(a)

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe0' in position 4: ordinal not in range(128)

To avoid this error you would have to encode it to bytes using codecs "utf-8" like this:

>>> f.write(a.encode("utf-8"))
>>> f.close()

and decode the data while reading using the codecs "utf-8":

>>> data = open("/tmp/test").read()
>>> data.decode("utf-8")
u'bats\xe0'

And also if you try to execute print on this string it will automatically decode using the "utf-8" codecs like this

>>> print a
batsà

In my CSS:

.borderless tr td {
    border: none !important;
    padding: 0px !important;
}

In my directive:

<table class='table borderless'>
    <tr class='borderless' ....>

I didn't put the 'borderless' for the td element.

Tested and it worked! All the borders and paddings are completely stripped off.

Here is how you do in Eloquent

$users = User::whereIn('id', array(1, 2, 3))->get();

And if you are using Query builder then :

$users = DB::table('users')->whereIn('id', array(1, 2, 3))->get();

The simplest way is using libraries like google-http-java-client but if you want parse the JSON response by yourself you can do that in a multiple ways, you can use org.json, json-simple, Gson, minimal-json, jackson-mapper-asl (from 1.x)... etc

A set of simple examples:

Using Gson:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;

public class Gson {

    public static void main(String[] args) {
    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);
            String json = EntityUtils.toString(result.getEntity(), "UTF-8");

            com.google.gson.Gson gson = new com.google.gson.Gson();
            Response respuesta = gson.fromJson(json, Response.class);

            System.out.println(respuesta.getExample());
            System.out.println(respuesta.getFr());

        } catch (IOException ex) {
        }
        return null;
    }

    public class Response{

        private String example;
        private String fr;

        public String getExample() {
            return example;
        }
        public void setExample(String example) {
            this.example = example;
        }
        public String getFr() {
            return fr;
        }
        public void setFr(String fr) {
            this.fr = fr;
        }
    }
}

Using json-simple:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;

public class JsonSimple {

    public static void main(String[] args) {

    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);

            String json = EntityUtils.toString(result.getEntity(), "UTF-8");
            try {
                JSONParser parser = new JSONParser();
                Object resultObject = parser.parse(json);

                if (resultObject instanceof JSONArray) {
                    JSONArray array=(JSONArray)resultObject;
                    for (Object object : array) {
                        JSONObject obj =(JSONObject)object;
                        System.out.println(obj.get("example"));
                        System.out.println(obj.get("fr"));
                    }

                }else if (resultObject instanceof JSONObject) {
                    JSONObject obj =(JSONObject)resultObject;
                    System.out.println(obj.get("example"));
                    System.out.println(obj.get("fr"));
                }

            } catch (Exception e) {
                // TODO: handle exception
            }

        } catch (IOException ex) {
        }
        return null;
    }
}

etc...

I encountered this issue while running an app on Java 1.6 while I have all three versions of Java 6,7,8 for different apps.I accessed the Navigator View and manually removed the unwanted facet from the facet.core.xml .Clean build and wallah!

<?xml version="1.0" encoding="UTF-8"?>

<fixed facet="jst.java"/>

<fixed facet="jst.web"/>

<installed facet="jst.web" version="2.4"/>

<installed facet="jst.java" version="6.0"/>

<installed facet="jst.utility" version="1.0"/>

if (MaterialTextBox.Text.length==0)

}

You can also use @SpringBootApplication, which according to Spring documentation does the same functionality as the following three annotations: @Configuration, @EnableAutoConfiguration @ComponentScan in one annotation.

@SpringBootApplication(exclude= {Foo.class})
public class MySpringConfiguration {}

I came across this answer when I was trying to follow this guide for OSX. What worked for me was, after running python get-pip, I had to ALSO easy_install pip. That fixed the issue of not being able to run pip at all. I did have a bunch of old macport stuff installed. That may have conflicted.

You need to use the bracket notation because key is a variable holding the key as a value

$.each(sjonObj, function(key,value){
   // console.log(value);
    if(value==""||value==null){
        delete sjonObj[key];
    }

});

delete sjonObj.key deletes the property called key from sjonObj, instead you need to use key as a variable holding the property name.

Note: Still it will not handle the nested objects

Also if you are looking for current file name along with the query string, you will just need following

basename($_SERVER['REQUEST_URI'])

It would provide you info like following example

file.php?arg1=val&arg2=val

And if you also want full path of file as well starting from root, e.g. /folder/folder2/file.php?arg1=val&arg2=val then just remove basename() function and just use fillowing

$_SERVER['REQUEST_URI']

This:

<select style="width: XXXpx;">

XXX = Any Number

Works great in Google Chrome v70.0.3538.110

In for xml path, if we define any value like [ for xml path('ENVLOPE') ] then these tags will be added with each row:

<ENVLOPE>
</ENVLOPE>

I'm a fan of declarative programming (look at how many SQL questions I answer), but the IoC containers I've looked at seem too arcane for their own good.

...or perhaps the developers of IoC containers are incapable of writing clear documentation.

...or else both are true to one degree or another.

I don't think the concept of an IoC container is bad. But the implementation has to be both powerful (that is, flexible) enough to be useful in a wide variety of applications, yet simple and easily understood.

It's probably six of one and half a dozen of the other. A real application (not a toy or demo) is bound to be complex, accounting for many corner cases and exceptions-to-the-rules. Either you encapsulate that complexity in imperative code, or else in declarative code. But you have to represent it somewhere.

A Promise represents a proxy for a value not necessarily known when the promise is created. It allows you to associate handlers to an asynchronous action's eventual success value or failure reason. This lets asynchronous methods return values like synchronous methods: instead of the final value, the asynchronous method returns a promise of having a value at some point in the future.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise

The deferred.promise() method allows an asynchronous function to prevent other code from interfering with the progress or status of its internal request. The Promise exposes only the Deferred methods needed to attach additional handlers or determine the state (then, done, fail, always, pipe, progress, state and promise), but not ones that change the state (resolve, reject, notify, resolveWith, rejectWith, and notifyWith).

If target is provided, deferred.promise() will attach the methods onto it and then return this object rather than create a new one. This can be useful to attach the Promise behavior to an object that already exists.

If you are creating a Deferred, keep a reference to the Deferred so that it can be resolved or rejected at some point. Return only the Promise object via deferred.promise() so other code can register callbacks or inspect the current state.

Simply we can say that a Promise represents a value that is not yet known where as a Deferred represents work that is not yet finished.

I had the same problem and I tried everything with no result,, What fixed the problem for me was changing the order of the library paths in the PATH variable. I had cygwin as well as some other compilers so there was probably some sort of collision between them. What I did was putting the C:\MinGW\bin; path first before all other paths and it fixed the problem for me!

forever module has a concept of multiple node.js servers, and can start, restart, stop and list currently running servers. It can also watch for changing files and restart node as needed.

Install it if you don't have it already:

npm install forever -g

After installing it, call the forever command: use the -w flag to watch file for changes:

forever -w ./my-script.js

In addition, you can watch directory and ignore patterns:

forever --watch --watchDirectory ./path/to/dir --watchIgnore *.log ./start/file

I had same issue with external libraries like ROS headers. I like to use following options in CMakeLists.txt for stricter compilation:

set(CMAKE_CXX_FLAGS "-std=c++0x -Wall -Wextra -Wstrict-aliasing -pedantic -Werror -Wunreachable-code ${CMAKE_CXX_FLAGS}")

However doing this causes all kind of pedantic errors in externally included libraries as well. The solution is to disable all pedantic warnings before you include external libraries and re-enable like this:

//save compiler switches
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wpedantic"

//Bad headers with problem goes here
#include <ros/ros.h>
#include <sensor_msgs/LaserScan.h>

//restore compiler switches
#pragma GCC diagnostic pop

In your example there is no big difference between str -> str and Function.identity() since internally it is simply t->t.

But sometimes we can't use Function.identity because we can't use a Function. Take a look here:

List<Integer> list = new ArrayList<>();
list.add(1);
list.add(2);

this will compile fine

int[] arrayOK = list.stream().mapToInt(i -> i).toArray();

but if you try to compile

int[] arrayProblem = list.stream().mapToInt(Function.identity()).toArray();

you will get compilation error since mapToInt expects ToIntFunction, which is not related to Function. Also ToIntFunction doesn't have identity() method.

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

setInterval(swapImages, 1000);

    first_list = [1, 2, 2, 5]
    second_list = [2, 5, 7, 9]

    newList=[]
    for i in first_list:
        newList.append(i)
    for z in second_list:
        if z not in newList:
            newList.append(z)
    newList.sort()
    print newList

[1, 2, 2, 5, 7, 9]

sklearn.cross_validation is now changed to sklearn.model_selection

Just use

from sklearn.model_selection import train_test_split

I think that will work.

You can grab the command line of any .Net application by accessing the Environment.CommandLine property. It will have the command line as a single string but parsing out the data you are looking for shouldn't be terribly difficult.

Having an empty Main method will not affect this property or the ability of another program to add a command line parameter.

In the Repository Browser of TortoiseSVN, find the branch that you want to create the new branch from. Right-click, Copy To.... and enter the new branch path. Now you can "switch" your local WC to that branch.

There is no native indexof method in java arrays.You will need to write your own method for this.

Today (2.5 years after this answer) you can safely use Array.forEach. As @ricosrealm suggests, decodeURIComponent was used in this function.

function getJsonFromUrl(url) {
  if(!url) url = location.search;
  var query = url.substr(1);
  var result = {};
  query.split("&").forEach(function(part) {
    var item = part.split("=");
    result[item[0]] = decodeURIComponent(item[1]);
  });
  return result;
}

actually it's not that simple, see the peer-review in the comments, especially:

• hash based routing (@cmfolio)
• array parameters (@user2368055)
• proper use of decodeURIComponent and non-encoded = (@AndrewF)
• non-encoded + (added by me)

For further details, see MDN article and RFC 3986.

Maybe this should go to codereview SE, but here is safer and regexp-free code:

function getJsonFromUrl(url) {
  if(!url) url = location.href;

This function can parse even URLs like

var url = "?foo%20e[]=a%20a&foo+e[%5Bx%5D]=b&foo e[]=c";
// {"foo e": ["a a",  "c",  "[x]":"b"]}

var obj = getJsonFromUrl(url)["foo e"];
for(var key in obj) { // Array.forEach would skip string keys here
  console.log(key,":",obj[key]);
}
/*
  0 : a a
  1 : c
  [x] : b
*/

Using ADO (AnonJr already explained) and utilizing SQL is possibly the best option for fetching data from a closed workbook without opening that in conventional way. Please watch this VIDEO.

OTHERWISE, possibly GetObject(<filename with path>) is the most CONCISE way. Worksheets remain invisible, however will appear in project explorer window in VBE just like any other workbook opened in conventional ways.

Dim wb As Workbook

Set wb = GetObject("C:\MyData.xlsx")  'Worksheets will remain invisible, no new window appears in the screen
' your codes here
wb.Close SaveChanges:=False

If you want to read a particular sheet, need not even define a Workbook variable

Dim sh As Worksheet
Set sh = GetObject("C:\MyData.xlsx").Worksheets("MySheet")
' your codes here
sh.Parent.Close SaveChanges:=False 'Closes the associated workbook

While you have specified the start anchor and the first letter, you have not done anything for the rest of the string. You seem to want repetition of that character class until the end of the string:

var regexp = /^\S*$/; // a string consisting only of non-whitespaces

Spring has a utility method for this:

TypedQuery<Profile> query = em.createNamedQuery(namedQuery, Profile.class);
...
return org.springframework.dao.support.DataAccessUtils.singleResult(query.getResultList());

If you just want to check if the file uploaded is an image you can just try to load it into <img> tag an check for any error callback.

Example:

var input = document.getElementsByTagName('input')[0];
var reader = new FileReader();

reader.onload = function (e) {
    imageExists(e.target.result, function(exists){
        if (exists) {

            // Do something with the image file.. 

        } else {

            // different file format

        }
    });
};

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


function imageExists(url, callback) {
    var img = new Image();
    img.onload = function() { callback(true); };
    img.onerror = function() { callback(false); };
    img.src = url;
}

make sure you are passing string to "replace" method. Had same issue and solved it by passing string. You can also make it to string using toString() method.

I too have been through this pain - if the query is dynamically generated (e.g. Hibernate Criteria) then I couldn't find a practical way to do it.

The good news for me was that I was only investigating union to solve a performance problem when using an 'or' in an Oracle database.

The solution Patrick posted (combining the results programmatically using a set) while ugly (especially since I wanted to do results paging as well) was adequate for me.

Expanding on jldupont's answer, you could create a wrapping element on the fly:

var target = document.getElementById('myElement');
var wrap = document.createElement('div');
wrap.appendChild(target.cloneNode(true));
alert(wrap.innerHTML);

I am cloning the element to avoid having to remove and reinsert the element in the actual document. This might be expensive if the element you wish to print has a very large tree below it, though.

Also be sure your app is subclassing MultiDexApplication

import android.support.multidex.MultiDexApplication

class App : MultiDexApplication()

or if not subclassing Application class, add to AndroidManifest.xml

<application
  android:name="android.support.multidex.MultiDexApplication"

Right click the project and give maven build,maven clean,maven generate resource and maven install.The jar file will automatically generate.

You could also setup your executable as an external tool, and mark the tool for Use output window. That way the output of the tool will be visible within Visual Studio itself, not a separate window.

Use files.exclude:

• Go to File -> Preferences -> Settings (or on Mac Code -> Preferences -> Settings)
• Pick the workspace settings tab

• Add this code to the settings.json file displayed on the right side:

  // Place your settings in this file to overwrite default and user settings.
  
  {
      "settings": {
          "files.exclude": {
              "**/.git": true,         // this is a default value
              "**/.DS_Store": true,    // this is a default value
  
              "**/node_modules": true, // this excludes all folders 
                                      // named "node_modules" from 
                                      // the explore tree
  
              // alternative version
              "node_modules": true    // this excludes the folder 
                                      // only from the root of
                                      // your workspace 
          }
      }
  }
  

If you chose File -> Preferences -> User Settings then you configure the exclude folders globally for your current user.

To skip . & .., you can use Dir::each_child.

Dir.each_child('/path/to/dir') do |filename|
  puts filename
end

Dir::children returns an array of the filenames.

<?php
    echo preg_replace( '#<li[^>]+>#', '<li class="col-sm-4">',
            wp_nav_menu(
                    array(
                        'menu' => $nav_menu, 
                        'container'  => false,
                        'container_class'   => false,
                        'menu_class'        => false,
                        'items_wrap'        => '%3$s',
                                            'depth'             => 1,
                                            'echo'              => false
                            )
                    )
            );
?>

Why aren't you doing this:

[chr(x) for x in [66,53,0,94]]

It's called a list comprehension. You can find plenty of information on Google, but here's the link to the Python (2.6) documentation on list comprehensions. You might be more interested in the Python 3 documenation, though.

Why use jQuery for this?

str = "123-4"; 
alert(str.substring(0,str.length - 1));

Of course if you must:

Substr w/ jQuery:

//example test element
 $(document.createElement('div'))
    .addClass('test')
    .text('123-4')
    .appendTo('body');

//using substring with the jQuery function html
alert($('.test').html().substring(0,$('.test').html().length - 1));

You could use array_map():

function add_quotes($str) {
    return sprintf("'%s'", $str);
}

$csv =  implode(',', array_map('add_quotes', $array));

DEMO

Also note that there is fputcsv if you want to write to a file.

Maybe good ol' cfront will do?

You can create something like c using CSS multiple-backgrounds.

div {
    background: linear-gradient(red, red),
                linear-gradient(blue, blue),
                linear-gradient(green, green);
    background-size: 30% 50%,
                     30% 60%,
                     40% 80%;
    background-position: 0% top,
                         calc(30% * 100 / (100 - 30)) top,
                         calc(60% * 100 / (100 - 40)) top;
    background-repeat: no-repeat;
}

Note, you still have to use linear-gradients for background types, because CSS will not allow you to control the background-size of a single color layer. So here we just make a single-color gradient. Then you can control the size/position of each of those blocks of color independently. You also have to make sure they don't repeat, or they'll just expand and cover the whole image.

The trickiest part here is background-position. A background-position of 0% puts your element's left edge at the left. 100% puts its right edge at the right. 50% centers is middle.

For a fun bit of math to solve that, you can guess the transform is probably linear, and just solve two little slope-intercept equations.

// (at 0%, the div's left edge is 0% from the left)
0 = m * 0 + b
// (at 100%, the div's right edge is 100% - width% from the left)
100 = m * (100 - width) + b
b = 0, m = 100 / (100 - width)

so to position our 40% wide div 60% from the left, we put it at 60% * 100 / (100 - 40) (or use css-calc).

To check for DIRECTORIES you should not use something like:

if exist c:\windows\

To work properly use:

if exist c:\windows\\.

note the "." at the end.

And it's unlikely too -- EOT is a fairly restrictive format that is supported only by IE. Both Safari 3.1 and Firefox 3.1 (well the current alpha) and possibly Opera 9.6 support true type font (ttf) embedding, and at least Safari supports SVG fonts through the same mechanism. A list apart had a good discussion about this a while back.

Because pypy is not 100% compatible, takes 8 gigs of ram to compile, is a moving target, and highly experimental, where cpython is stable, the default target for module builders for 2 decades (including c extensions that don't work on pypy), and already widely deployed.

Pypy will likely never be the reference implementation, but it is a good tool to have.

Carl W:

This effect can occur on non-input elements, too. I've found the following works as a more general solution

:focus {
  outline-color: transparent;
  outline-style: none;
}

I’ll explain this:

• :focus means it styles the elements that are in focus. So we are styling the elements in focus.
• outline-color: transparent; means that the blue glow is transparent.
• outline-style: none; does the same thing.

You can use HTTP URLs as if they were local files, thanks to PHP's wrappers

You can get the contents from an URL via file_get_contents() and then echo it, or even read it directly using readfile()

$file = file_get_contents('http://example.com/rss');
echo $file;

or

readfile('http://example.com/rss');

Don't forget to set the correct MIME type before outputing anything, though.

header('Content-type: text/xml');

Even better: use the inspect.isclass function.

>>> import inspect
>>> class X(object):
...     pass
... 
>>> inspect.isclass(X)
True

>>> x = X()
>>> isinstance(x, X)
True
>>> y = 25
>>> isinstance(y, X)
False

FileAppender appender = repository.GetAppenders().OfType<FileAppender>().FirstOrDefault();
if (appender != null)
    logger.DebugFormat("log file located at : {0}", appender.File);
else
    logger.Error("Could not locate fileAppender");

For adding argument to delay function.

First setup a dictionary then add it as the userInfo. Unwrap the info with the timer as the argument.

let arg : Int = 42
let infoDict : [String : AnyObject] = ["argumentInt", arg]

NSTimer.scheduledTimerWithTimeInterval(NSTimeInterval(3), target: self, selector: "functionHereWithArgument:", userInfo: infoDict, repeats: false)

Then in the called function

func functionHereWithArgument (timer : NSTimer)
{
    if let userInfo = timer.userInfo as? Dictionary<String, AnyObject>
    {
         let argumentInt : Int = (userInfo[argumentInt] as! Int)
    }
}

You cannot call a function that requires arguments in a template. Write a template tag or filter instead.

If you don't want add the /s regex modifier (perhaps you still want . to retain its original meaning elsewhere in the regex), you may also use a character class. One possibility:

[\S\s]

a character which is not a space or is a space. In other words, any character.

You can also change modifiers locally in a small part of the regex, like so:

(?s:.)

In case you installed yarn globally like this

$ sudo npm install -g yarn

Just run this in terminal

$ sudo npm uninstall -g yarn

Tested now on my local machine running Ubuntu. Works perfect!

String Formatting:

a = 6.789809823
print('%.2f' %a)

OR

print ("{0:.2f}".format(a)) 

Round Function can be used:

print(round(a, 2))

Good thing about round() is that, we can store this result to another variable, and then use it for other purposes.

b = round(a, 2)
print(b)

This is a problem related permission. Make sure that the current user has access to the folder which contains installation files.

Here's a short piece I use when I need to filter on something after the list comprehension. Just a combination of filter, lambda, and lists (otherwise known as the loyalty of a cat and the cleanliness of a dog).

In this case I'm reading a file, stripping out blank lines, commented out lines, and anything after a comment on a line:

# Throw out blank lines and comments
with open('file.txt', 'r') as lines:        
    # From the inside out:
    #    [s.partition('#')[0].strip() for s in lines]... Throws out comments
    #   filter(lambda x: x!= '', [s.part... Filters out blank lines
    #  y for y in filter... Converts filter object to list
    file_contents = [y for y in filter(lambda x: x != '', [s.partition('#')[0].strip() for s in lines])]

http://lab.abhinayrathore.com/jquery_cdn/ is a page where you can find links to the latest versions of jQuery, jQuery UI and Themes for Google and Microsoft CDN's.

This page automatically updates with the latest links from the CDN.

For Magento, you check validation of form by something like below.

You can try this:

require(["jquery"], function ($) {
    $(document).ready(function () {
        $('#my-button-name').click(function () { // The button type should be "button" and not submit
            if ($('#form-name').valid()) {
                alert("Validation pass");
                return false;
            }else{
                alert("Validation failed");
                return false;
            }
        });
    });
});

Hope this may help you!

Expand your database, expand your table right click on your table and select design from dropdown.

Now go Column properties below of it scroll down and find Identity Specification, expand it and you will find Is Identity make it Yes. Now choose Identity Increment right below of it give the value you want to increment in it.

Working with GPX files with Xcode compatibility

I followed the link given by AlexWien and it was extremely useful: https://blackpixel.com/writing/2013/05/simulating-locations-with-xcode.html

But, I spent quite some time searching for how to generate .gpx files with waypoints (wpt tags), as Xcode only accepts wpt tags.

The following tool converts a Google Maps link (also works with Google Maps Directions) to a .gpx file.

https://mapstogpx.com/mobiledev.php

Simulating a trip duration is supported, custom durations can be specified. Just select Xcode and it gets the route as waypoints.

Try this:

SET TERMOUT OFF; 
spool M:\Documents\test;
select * from employees;
/
spool off;

Thanks Justin, Pascal for guiding me to the right direction. I was also facing the same issue with Hibernate 3.5.3. Your research and pointers to the right classes had helped me identify the issue and do a fix.

For the benefit for those who are still stuck with Hibernate 3.5 and using oid + byte[] + @LoB combination, following is what I have done to fix the issue.

1. I created a custom BlobType extending MaterializedBlobType and overriding the set and the get methods with the oid style access.

   public class CustomBlobType extends MaterializedBlobType {
   
   private static final String POSTGRESQL_DIALECT = PostgreSQLDialect.class.getName();
   
   /**
    * Currently set dialect.
    */
   private String dialect = hibernateConfiguration.getProperty(Environment.DIALECT);
   
   /*
    * (non-Javadoc)
    * @see org.hibernate.type.AbstractBynaryType#set(java.sql.PreparedStatement, java.lang.Object, int)
    */
   @Override
   public void set(PreparedStatement st, Object value, int index) throws HibernateException, SQLException {
       byte[] internalValue = toInternalFormat(value);
   
       if (POSTGRESQL_DIALECT.equals(dialect)) {
           try {
   
   //I had access to sessionFactory through a custom sessionFactory wrapper.
   st.setBlob(index, Hibernate.createBlob(internalValue, sessionFactory.getCurrentSession()));
               } catch (SystemException e) {
                   throw new HibernateException(e);
               }
           } else {
               st.setBytes(index, internalValue);
           }
       }
   
   /*
    * (non-Javadoc)
    * @see org.hibernate.type.AbstractBynaryType#get(java.sql.ResultSet, java.lang.String)
    */
   @Override
   public Object get(ResultSet rs, String name) throws HibernateException, SQLException {
       Blob blob = rs.getBlob(name);
       if (rs.wasNull()) {
           return null;
       }
       int length = (int) blob.length();
       return toExternalFormat(blob.getBytes(1, length));
     }
   }
   

   2. Register the CustomBlobType with Hibernate. Following is what i did to achieve that.

      hibernateConfiguration= new AnnotationConfiguration();
      Mappings mappings = hibernateConfiguration.createMappings();
      mappings.addTypeDef("materialized_blob", "x.y.z.BlobType", null);
      

ok, so my problem was that I tried to install the package with yum which is the primary tool for getting, installing, deleting, querying, and managing Red Hat Enterprise Linux RPM software packages from official Red Hat software repositories, as well as other third-party repositories.

But I'm using ubuntu and The usual way to install packages on the command line in Ubuntu is with apt-get. so the right command was:

sudo apt-get install libstdc++.i686

For languages not specifying a memory model, you are writing code for the language and the memory model specified by the processor architecture. The processor may choose to re-order memory accesses for performance. So, if your program has data races (a data race is when it's possible for multiple cores / hyper-threads to access the same memory concurrently) then your program is not cross platform because of its dependence on the processor memory model. You may refer to the Intel or AMD software manuals to find out how the processors may re-order memory accesses.

Very importantly, locks (and concurrency semantics with locking) are typically implemented in a cross platform way... So if you are using standard locks in a multithreaded program with no data races then you don't have to worry about cross platform memory models.

Interestingly, Microsoft compilers for C++ have acquire / release semantics for volatile which is a C++ extension to deal with the lack of a memory model in C++ http://msdn.microsoft.com/en-us/library/12a04hfd(v=vs.80).aspx. However, given that Windows runs on x86 / x64 only, that's not saying much (Intel and AMD memory models make it easy and efficient to implement acquire / release semantics in a language).

For Apache server, you should check mod_expires for setting Expires and Cache-Control headers.

Alternatively, you can use Header directive to add Cache-Control on your own:

Header set Cache-Control "max-age=290304000, public"

You can install pip (or any other package) with easy_install almost as described in the first answer. However you will need a HTTPS proxy, too. The full sequence of commands is:

set http_proxy=http://proxy.myproxy.com
set https_proxy=http://proxy.myproxy.com
easy_install pip

You might also want to add a port to the proxy, such as http{s}_proxy=http://proxy.myproxy.com:8080

[a-zA-Z] should do that just fine.

You can reference the cheat sheet.

First of all: I'm the author of the The Single Page Interface Manifesto cited by raganwald

As raganwald has explained very well, the most important aspect of the Single Page Interface (SPI) approach used in FaceBook and Twitter is the use of hash # in URLs

The character ! is added only for Google purposes, this notation is a Google "standard" for crawling web sites intensive on AJAX (in the extreme Single Page Interface web sites). When Google's crawler finds an URL with #! it knows that an alternative conventional URL exists providing the same page "state" but in this case on load time.

In spite of #! combination is very interesting for SEO, is only supported by Google (as far I know), with some JavaScript tricks you can build SPI web sites SEO compatible for any web crawler (Yahoo, Bing...).

The SPI Manifesto and demos do not use Google's format of ! in hashes, this notation could be easily added and SPI crawling could be even easier (UPDATE: now ! notation is used and remains compatible with other search engines).

Take a look to this tutorial, is an example of a simple ItsNat SPI site but you can pick some ideas for other frameworks, this example is SEO compatible for any web crawler.

The hard problem is to generate any (or selected) "AJAX page state" as plain HTML for SEO, in ItsNat is very easy and automatic, the same site is in the same time SPI or page based for SEO (or when JavaScript is disabled for accessibility). With other web frameworks you can ever follow the double site approach, one site is SPI based and another page based for SEO, for instance Twitter uses this "double site" technique.

I just had this same problem during a SSRS development of a Custom Report for MS CRM Dynamics 2011.

The reason because it occurred is because I am using some Hidden Parameters and for some of them I forget to give a default value.

So, because of I have few time to finish the report I forget to put the default value for some Parameters and I risked to lost more time to fix it.

Luckily I found it very fast because the error shows the textbox and the paragraph with the first wrong parameter but it didn't shows the name of the parameter:

"I cannot post the image of the error because this website don't allows me"

In general during SSRS developments it's very important to remember: - To put the report parameters in the correct sequence (the referred ones for first es. parameters inherited from master report or parameters essentials for sub-datasets) - To assign a default value to the Hide and Internal Parameters.

Use Apache commons beanutils:

static void copyProperties(Object dest, Object orig) -Copy property values from the origin bean to the destination bean for all cases where the property names are the same.

http://commons.apache.org/proper/commons-beanutils/

For a single file you can use -O instead of -o filename to use the last segment of the URL path as the filename. Example:

curl http://example.com/folder/big-file.iso -O

will save the results to a new file named big-file.iso in the current folder. In this way it works similar to wget but allows you to specify other curl options that are not available when using wget.

You can alternatively use the CASE-WHEN TSQL statement in combination with pragma_table_info to know if a column exists:

select case(CNT) 
    WHEN 0 then printf('not found')
    WHEN 1 then printf('found')
    END
FROM (SELECT COUNT(*) AS CNT FROM pragma_table_info('myTableName') WHERE name='columnToCheck') 

Log from Silverlight

When using NLog with Silverlight you can send the trace to the server side via the provided web service. You can also write to a local file in the Isolated Storage, which come in handy if the web server is unavailable. See here for details, i.e. use something like this to make yourself a target:

namespace NLogTargets
{
    [Target("IsolatedStorageTarget")]
    public sealed class IsolatedStorageTarget : TargetWithLayout
    {
        IsolatedStorageFile _storageFile = null;
        string _fileName = "Nlog.log"; // Default. Configurable through the 'filename' attribute in nlog.config

        public IsolatedStorageTarget()
        {
        }

        ~IsolatedStorageTarget()
        {
            if (_storageFile != null)
            {
                _storageFile.Dispose();
                _storageFile = null;
            }
        }

        public string filename
        {
            set
            {
                _fileName = value; 
            }
            get
            {
                return _fileName;  
            }
         }

        protected override void Write(LogEventInfo logEvent)
        {
            try
            {
                writeToIsolatedStorage(this.Layout.Render(logEvent));
            }
            catch (Exception e)
            {
                // Not much to do about his....
            }
        }

        public void writeToIsolatedStorage(string msg)
        {
            if (_storageFile == null)
                _storageFile = IsolatedStorageFile.GetUserStoreForApplication();
            using (IsolatedStorageFile isolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
            {
                // The isolated storage is limited in size. So, when approaching the limit
                // simply purge the log file. (Yeah yeah, the file should be circular, I know...)
                if (_storageFile.AvailableFreeSpace < msg.Length * 100)
                {
                    using (IsolatedStorageFileStream stream = new IsolatedStorageFileStream(_fileName, FileMode.Truncate, FileAccess.Write, isolatedStorage))
                    { }
                }
                // Write to isolated storage
                using (IsolatedStorageFileStream stream = new IsolatedStorageFileStream(_fileName, FileMode.Append, FileAccess.Write, isolatedStorage))
                {
                    using (TextWriter writer = new StreamWriter(stream))
                    {
                        writer.WriteLine(msg);
                    }
                }
            }
        }
    } 
}

I have experienced that kind of issue before and now I'm not using header('Location: pageExample.php'); anymore, instead I'm using javascript's document.location.

Change your:

header('Location: page1.php');

To something like this:

echo "<script type='text/javascript'> document.location = 'page1.php'; </script>";

And what is the purpose of echo $_POST['cancel']; by the way?, just delete that line if what you want is just the redirection. I've been using that <script> every time and it doesn't fail me. :-)

I found what seems to be the latest 2014 and 2012 SQL Server Management Studio releases here Previous SQL Server Management Studio Releases

Based on @Ted's answer, I've used this extension:

extension XCTestCase {

    // Based on https://stackoverflow.com/a/33855219
    func waitFor<T>(object: T, timeout: TimeInterval = 5, file: String = #file, line: UInt = #line, expectationPredicate: @escaping (T) -> Bool) {
        let predicate = NSPredicate { obj, _ in
            expectationPredicate(obj as! T)
        }
        expectation(for: predicate, evaluatedWith: object, handler: nil)

        waitForExpectations(timeout: timeout) { error in
            if (error != nil) {
                let message = "Failed to fulful expectation block for \(object) after \(timeout) seconds."
                let location = XCTSourceCodeLocation(filePath: file, lineNumber: line)
                let issue = XCTIssue(type: .assertionFailure, compactDescription: message, detailedDescription: nil, sourceCodeContext: .init(location: location), associatedError: nil, attachments: [])
                self.record(issue)
            }
        }
    }

}

You can use it like this

let element = app.staticTexts["Name of your element"]
waitFor(object: element) { $0.exists }

It also allows for waiting for an element to disappear, or any other property to change (by using the appropriate block)

waitFor(object: element) { !$0.exists } // Wait for it to disappear

The @Transactional annotation takes a timeout parameter where you can specify timeout in seconds for a specific method in the @RestController

@RequestMapping(value = "/method",
    method = RequestMethod.POST,
    produces = MediaType.APPLICATION_JSON_VALUE)
@Timed
@Transactional(timeout = 120)

I can tell you for Windows.

1. Install Java Extension Pack and Code Runner Extension from VS Code Extensions.

2. Edit your java home location in VS Code settings, "java.home": "C:\\Program Files\\Java\\jdk-9.0.4".

3. Check if javac is recognized in VS Code internal terminal. If this check fails, try opening VS Code as administrator.

4. Create a simple Java program in Main.java file as:

public class Main {
    public static void main(String[] args) {
        System.out.println("Hello world");     
    }
}

Note: Do not add package in your main class.

5. Right click anywhere on the java file and select run code.

6. Check the output in the console.

Done, hope this helps.

I also in need of using command line approach to do the packaging and dmg creation "programmatically in a script". The best answer I found so far is from Adium project' Release building framework (See R1). There is a custom script(AdiumApplescriptRunner) to allow you avoid OSX WindowsServer GUI interaction. "osascript applescript.scpt" approach require you to login as builder and run the dmg creation from a command line vt100 session.

OSX package management system is not so advanced compared to other Unixen which can do this task easily and systematically.
