It is perfectly valid to leave off the protocol. The URL spec has been very clear about this for years, and I've yet to find a browser that doesn't understand it. I don't know why this technique isn't better known; it's the perfect solution to the thorny problem of crossing HTTP/HTTPS boundaries. More here: Http-https transitions and relative URLs

Use the special bash variable "$?" like so:

function_output=$(my_function)
function_return_value=$?

Here's another way of doing it with a WHS script:

Set objWMIService = GetObject("Winmgmts:root\cimv2")

For Each objComputer in _
    objWMIService.InstancesOf("Win32_ComputerSystem")

    objComputer.rename "NewComputerName", NULL, NULL

Press the start button in visual studio. Then go to the location where your solution is stored and open the folder of your main project then the bin folder. If your application was running in debug mode then go to the debug folder. If running in release mode then go to the release folder. You should find your exe there.

For adding some more information, your example will work without the @ symbol (it prevents escaping with \), this way:

string foo = "this \"word\" is escaped!";

It will work both ways but I prefer the double-quote style for it to be easier working, for example, with filenames (with lots of \ in the string).

I played around with nico's answer a little and it felt jumpy. Did a bit of investigation and found window.requestAnimationFrame which is a function that is called on each repaint cycle. This allows for a more clean-looking animation. Still trying to hone in on good default values for step size but for my example things look pretty good using this implementation.

var smoothScroll = function(elementId) {
    var MIN_PIXELS_PER_STEP = 16;
    var MAX_SCROLL_STEPS = 30;
    var target = document.getElementById(elementId);
    var scrollContainer = target;
    do {
        scrollContainer = scrollContainer.parentNode;
        if (!scrollContainer) return;
        scrollContainer.scrollTop += 1;
    } while (scrollContainer.scrollTop == 0);

    var targetY = 0;
    do {
        if (target == scrollContainer) break;
        targetY += target.offsetTop;
    } while (target = target.offsetParent);

    var pixelsPerStep = Math.max(MIN_PIXELS_PER_STEP,
                                 (targetY - scrollContainer.scrollTop) / MAX_SCROLL_STEPS);

    var stepFunc = function() {
        scrollContainer.scrollTop =
            Math.min(targetY, pixelsPerStep + scrollContainer.scrollTop);

        if (scrollContainer.scrollTop >= targetY) {
            return;
        }

        window.requestAnimationFrame(stepFunc);
    };

    window.requestAnimationFrame(stepFunc);
}

It depends on what you are trying to do.

file, err := os.Open("file.txt")
fmt.print(file)

The reason it outputs &{0xc082016240}, is because you are printing the pointer value of a file-descriptor (*os.File), not file-content. To obtain file-content, you may READ from a file-descriptor.

To read all file content(in bytes) to memory, ioutil.ReadAll

package main

import (
    "fmt"
    "io/ioutil"
    "os"
    "log"
)

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()


  b, err := ioutil.ReadAll(file)
  fmt.Print(b)
}

But sometimes, if the file size is big, it might be more memory-efficient to just read in chunks: buffer-size, hence you could use the implementation of io.Reader.Read from *os.File

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()


    buf := make([]byte, 32*1024) // define your buffer size here.

    for {
        n, err := file.Read(buf)

        if n > 0 {
            fmt.Print(buf[:n]) // your read buffer.
        }

        if err == io.EOF {
            break
        }
        if err != nil {
            log.Printf("read %d bytes: %v", n, err)
            break
        }
    }

}

Otherwise, you could also use the standard util package: bufio, try Scanner. A Scanner reads your file in tokens: separator.

By default, scanner advances the token by newline (of course you can customise how scanner should tokenise your file, learn from here the bufio test).

package main

import (
    "fmt"
    "os"
    "log"
    "bufio"
)

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()

    scanner := bufio.NewScanner(file)

    for scanner.Scan() {             // internally, it advances token based on sperator
        fmt.Println(scanner.Text())  // token in unicode-char
        fmt.Println(scanner.Bytes()) // token in bytes

    }
}

Lastly, I would also like to reference you to this awesome site: go-lang file cheatsheet. It encompassed pretty much everything related to working with files in go-lang, hope you'll find it useful.

Answer in short: (search your situation)

• 1.compareTo(0) (return: 1)
• 1.compareTo(1) (return: 0)
• 0.comapreTo(1) (return: -1)

The easiest way is to follow these steps:

1. run android emulator 1.5
2. open up the menu
3. go to settings
4. wireless settings(first block) and right at the bottom turn off airplane mode.

By now you would've seen on top 3g and your established connection.

I've tried using the autoplay tag, and .load() .play() still need to be called at least in chrome (maybe its my settings).

the simplest cross browser way to do this with jquery using your example would be

var $video = $('#divVideo video'),
videoSrc = $('source', $video).attr('src', videoFile);
$video[0].load();
$video[0].play();

However the way I'd suggest you do it (for legibility and simplicity) is

var video = $('#divVideo video')[0];
video.src = videoFile;
video.load();
video.play();

Further Reading http://msdn.microsoft.com/en-us/library/ie/hh924823(v=vs.85).aspx#ManagingPlaybackInJavascript

Additional info: .load() only works if there is an html source element inside the video element (i.e. <source src="demo.mp4" type="video/mp4" />)

The non jquery way would be:

HTML

<div id="divVideo">
  <video id="videoID" controls>
    <source src="test1.mp4" type="video/mp4" />
  </video>
</div>

JS

var video = document.getElementById('videoID');
video.src = videoFile;
video.load();
video.play();

SQL is Structured Query Language

MySQL is a relational database management system. You can submit SQL queries to the MySQL database to store, retrieve, modify or delete data.

both <button> tag and <input type="button"> accept a title attribute..

The accepted answer explains already well why the warning occurs. If you simply want to control the warnings, one could use precision_recall_fscore_support. It offers a (semi-official) argument warn_for that could be used to mute the warnings.

(_, _, f1, _) = metrics.precision_recall_fscore_support(y_test, y_pred,
                                                        average='weighted', 
                                                        warn_for=tuple())

As mentioned already in some comments, use this with care.

Try creating an inline table-valued function. Example:

CREATE FUNCTION dbo.fxnExample (@Parameter1 INTEGER)
RETURNS TABLE
AS
RETURN
(
    SELECT Field1, Field2
    FROM SomeTable
    WHERE Field3 = @Parameter1
)

-- Then call like this, just as if it's a table/view just with a parameter
SELECT * FROM dbo.fxnExample(1)

If you view the execution plan for the SELECT you will not see a mention of the function at all and will actually just show you the underlying tables being queried. This is good as it means statistics on the underlying tables will be used when generating an execution plan for the query.

The thing to avoid would be a multi-statement table valued function as underlying table statistics will not be used and can result in poor performance due to a poor execution plan.
Example of what to avoid:

CREATE FUNCTION dbo.fxnExample (@Parameter1 INTEGER)
    RETURNS @Results TABLE(Field1 VARCHAR(10), Field2 VARCHAR(10))
AS
BEGIN
    INSERT @Results
    SELECT Field1, Field2
    FROM SomeTable
    WHERE Field3 = @Parameter1

    RETURN
END

Subtly different, but with potentially big differences in performance when the function is used in a query.

If you would like to remove by a list of IDs this works great.

db.CollectionName.remove({
    "_id": {
        $in: [
            ObjectId("0930292929292929292929"),
            ObjectId("0920292929292929292929")
        ]
     }
}) 

To me, my final solution was a mix of several answers:

    var newWindow = window.open();
    newWindow.document.open();
    newWindow.document.write('<html><link rel="stylesheet" href="css/normalize-3.0.2.css" type="text/css" />'
            + '<link rel="stylesheet" href="css/default.css" type="text/css" />'
            + '<link rel="stylesheet" media="print" href="css/print.css" type="text/css" />');

    newWindow.document.write('<body onload="window.print();" onfocus="window.setTimeout(function() { window.close(); }, 100);">');
    newWindow.document.write(document.getElementById(<ID>).innerHTML);
    newWindow.document.write('</body></html>');
    newWindow.document.close();
    newWindow.focus();

Using Jest, you can do it like this:

test('it calls start logout on button click', () => {
    const mockLogout = jest.fn();
    const wrapper = shallow(<Component startLogout={mockLogout}/>);
    wrapper.find('button').at(0).simulate('click');
    expect(mockLogout).toHaveBeenCalled();
});

You've got a few things going on there. One, why a class? Do you actually have multiple of these on the page? The CSS suggests you can't. If not you should use an ID - it's faster to select both in CSS and jQuery:

<div id=bottomMenu>You read it all.</div>

Second you've got a few crazy things going on in that CSS - in particular the z-index is supposed to just be a number, not measured in pixels. It specifies what layer this tag is on, where each higher number is closer to the user (or put another way, on top of/occluding tags with lower z-indexes).

The animation you're trying to do is basically .fadeIn(), so just set the div to display: none; initially and use .fadeIn() to animate it:

$('#bottomMenu').fadeIn(2000);

.fadeIn() works by first doing display: (whatever the proper display property is for the tag), opacity: 0, then gradually ratcheting up the opacity.

Full working example:

http://jsfiddle.net/b9chris/sMyfT/

CSS:

#bottomMenu {
    display: none;
    position: fixed;
    left: 0; bottom: 0;
    width: 100%; height: 60px;
    border-top: 1px solid #000;
    background: #fff;
    z-index: 1;
}

JS:

var $win = $(window);

function checkScroll() {
    if ($win.scrollTop() > 100) {
        $win.off('scroll', checkScroll);
        $('#bottomMenu').fadeIn(2000);
    }
}

$win.scroll(checkScroll);

$array = array('foo' => 'bar', 33 => 'bin', 'lorem' => 'ipsum');
$array = array_values($array);
echo $array[0]; //bar
echo $array[1]; //bin
echo $array[2]; //ipsum

purls $.params() used without a parameter will give you a key-value object of the parameters.

jQuerys $.param() will build a querystring from the supplied object/array.

var params = parsedUrl.param();
delete params["page"];

var newUrl = "?page=" + $(this).val() + "&" + $.param(params);

Update
I've no idea why I used delete here...

var params = parsedUrl.param();
params["page"] = $(this).val();

var newUrl = "?" + $.param(params);

This might have changed since the original answer was written, but it looks like you can now use the Models populate function to do this without having to execute an extra findOne. See: http://mongoosejs.com/docs/api.html#model_Model.populate. You'd want to use this inside the save handler just like the findOne is.

Yes, you can invalidate cache.

The cache is stored in an object called require.cache which you can access directly according to filenames (e.g. - /projects/app/home/index.js as opposed to ./home which you would use in a require('./home') statement).

delete require.cache['/projects/app/home/index.js'];

Our team has found the following module useful. To invalidate certain groups of modules.

https://www.npmjs.com/package/node-resource

heres a jquery plugin to do that

(function($) {
    $.fn.onEnter = function(func) {
        this.bind('keypress', function(e) {
            if (e.keyCode == 13) func.apply(this, [e]);    
        });               
        return this; 
     };
})(jQuery);

to use it, include the code and set it up like this:

$( function () {
    console.log($("input"));
    $("input").onEnter( function() {
        $(this).val("Enter key pressed");                
    });
});

jsfiddle of it here http://jsfiddle.net/VrwgP/30/

I had issues with some of the above solutions, with getting the correct "bounding_box" or new size of the image. Therefore here is my version

def rotation(image, angleInDegrees):
    h, w = image.shape[:2]
    img_c = (w / 2, h / 2)

    rot = cv2.getRotationMatrix2D(img_c, angleInDegrees, 1)

    rad = math.radians(angleInDegrees)
    sin = math.sin(rad)
    cos = math.cos(rad)
    b_w = int((h * abs(sin)) + (w * abs(cos)))
    b_h = int((h * abs(cos)) + (w * abs(sin)))

    rot[0, 2] += ((b_w / 2) - img_c[0])
    rot[1, 2] += ((b_h / 2) - img_c[1])

    outImg = cv2.warpAffine(image, rot, (b_w, b_h), flags=cv2.INTER_LINEAR)
    return outImg

Cannot agree more with the above comments. Above that, there are some more differences like

In Linear Regression, residuals are assumed to be normally distributed. In Logistic Regression, residuals need to be independent but not normally distributed.

Linear Regression assumes that a constant change in the value of the explanatory variable results in constant change in the response variable. This assumption does not hold if the value of the response variable represents a probability (in Logistic Regression)

GLM(Generalized linear models) does not assume a linear relationship between dependent and independent variables. However, it assumes a linear relationship between link function and independent variables in logit model.

Deny from all 

is an .htaccess command(the actual content of that file you are trying to view). Not a denial of being able to edit the file. Just reopen the .htaccess file in the text viewer of choice and make the alterations as you so desire, save it, then reupload it to your folder of choice.

Though I think inadvertently you are blocking even yourself from viewing said application once uploaded.

I would do something like:

order deny,allow
deny from all
allow from 127.0.0.1

which will deny everyone but the IP in the allow from line, which you would change the IP to match your IP which you can obtain from http://www.whatismyip.com/ or similar site.

An alternative to the rather unintuitive [::-1] syntax is this:

>>> test = "abcba"
>>> test == ''.join(reversed(test))
True

The reversed function returns a reversed sequence of the characters in test.

''.join() joins those characters together again with nothing in between.

If you need n % m then:

int i = (n < 0) ? (m - (abs(n) % m) ) %m : (n % m);

mathematical explanation:

n = -1 * abs(n)
-> n % m = (-1 * abs(n) ) % m
-> (-1 * (abs(n) % m) ) % m
-> m - (abs(n) % m))

I don't know how was the plugin the time the question was asked (2009), but I faced the same problem today and solved it this way:

1. Give your select tag a name attribute. For example in this case

   <select name="myselect">

2. Instead of working with the attribute value="default" in the tag option, disable the default option as suggested by Jeremy Visser or set value=""

   <option disabled="disabled">Choose...</option>

   or

   <option value="">Choose...</option>

3. Set the plugin validation rule

   $( "#YOUR_FORM_ID" ).validate({ rules: { myselect: { required: true } } });

   or

   <select name="myselect" class="required">

Obs: redsquare's solution works only if you have just one select in your form. If you want his solution to work with more than one select add a name attribute to your select.

Hope it helps! :)

This is a classic python unicode pain point! Consider the following:

a = u'bats\u00E0'
print a
 => batsà

All good so far, but if we call str(a), let's see what happens:

str(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)

Oh dip, that's not gonna do anyone any good! To fix the error, encode the bytes explicitly with .encode and tell python what codec to use:

a.encode('utf-8')
 => 'bats\xc3\xa0'
print a.encode('utf-8')
 => batsà

Voil\u00E0!

The issue is that when you call str(), python uses the default character encoding to try and encode the bytes you gave it, which in your case are sometimes representations of unicode characters. To fix the problem, you have to tell python how to deal with the string you give it by using .encode('whatever_unicode'). Most of the time, you should be fine using utf-8.

Solution 1 (Elegant approach with great user experience)

HTML

<input id="inputID" class="uppercase" name="inputName" value="" />

CSS

.uppercase{
    text-transform: uppercase;
}

JS

$('#inputID').on('blur', function(){
    this.value = this.value.toUpperCase();
});

By using CSS text-transform: uppercase; you'll eliminate the animation of lower to uppercase as the user types into the field.

Use blur event to handle converting to uppercase. This happens behind the scene as CSS took care of the user's visually appealing masking.

Solution 2 (Great, but less elegant)

If you insist on using keyup, here it is...

$('#inputID').on('keyup', function(){
    var caretPos = this.selectionStart;
    this.value = this.value.toUpperCase();
    this.setSelectionRange(caretPos, caretPos);
});

User would notice the animation of lowercase to uppercase as they type into the field. It gets the job done.

Solution 3 (Just get the job done)

$('#inputID').on('keyup', function(){
    this.value = this.value.toUpperCase();
});

This method is most commonly suggested but I do not recommend.

The downside of this solution is you'll be annoying the user as the cursor's caret position keeps jumping to the end of the text after every key input. Unless you know your users will never encounter typos or they will always clear the text and retype every single time, this method works.

Jumping off from Alex Montoya's approach for multiple file input elements

const inputFiles = document.querySelectorAll('input[type="file"]');
const formData = new FormData();

for (const file of inputFiles) {
    formData.append(file.name, file.files[0]);
}

fetch(url, {
    method: 'POST',
    body: formData })

I am unable to get this working with the javac compiler, and I get the same error.

Error:(9, 14) java: package lombok does not exist

I have enabled annotation processor, and have also tried rebuilding the project, invalidate cache/restart. Doesn't help.

I did however get it to work partially with eclipse compiler. I say partial because although the build passes successfully, the editor still complains about "Cannot resolve symbol".

Idea - 15.04 community edition Lombok - 1.16.6 Lombok plugin (https://github.com/mplushnikov/lombok-intellij-plugin) - 0.9.8 JDK - 1.8.0_51

Update: Ok, I finally got this working. Mine was a gradle project, and lombok was configured as a custom "provided" configuration. Worked fine after adding this in build.gradle

idea {
 module {
     scopes.PROVIDED.plus += [configurations.provided]
    }
}

So, 3 steps

1. Install Lombok plugin from File->Settings->Plugins
2. Enable Annotation Processor (javac compiler works too)
3. Ensure that you have build.gradle or pom.xml updated for idea if you are adding lombok as a custom config.

To add a little to Robert Knight's answer, since the title of the post itself doesn't mention foreign keys (and since his doesn't have complete code samples and since SO's comment code blocks don't show as well as the answers' code blocks), I'll add this for unique constraints. Either of these work to drop the constraint:

ALTER TABLE `table_name` DROP KEY `uc_name`;

or

ALTER TABLE `table_name` DROP INDEX `uc_name`;

I would advise you to use a custom event rather than triggering a digest cycle.

I've come to find that broadcasting custom events and registering listeners for this events is a good solution for triggering an action you wish to occur whether or not you are in a digest cycle.

By creating a custom event you are also being more efficient with your code because you are only triggering listeners subscribed to said event and NOT triggering all watches bound to the scope as you would if you invoked scope.$apply.

$scope.$on('customEventName', function (optionalCustomEventArguments) {
   //TODO: Respond to event
});


$scope.$broadcast('customEventName', optionalCustomEventArguments);

first convert your date string to date then convert it to timestamp by using following set of line

Date date=new Date();
Timestamp timestamp = new Timestamp(date.getTime());//instead of date put your converted date
Timestamp myTimeStamp= timestamp;

• Visit phpmyadmin
• Select your database and click on structure
• In front of your table, you can see Empty, click on it to clear all the entries from the selected table.

Or you can do the same using sql query:

Click on SQL present along side Structure

TRUNCATE tablename; //offers better performance, but used only when all entries need to be cleared
or
DELETE FROM tablename; //returns the number of rows deleted

Refer to DELETE and TRUNCATE for detailed documentaion

That only means that an undefined column or parameter name was detected. The errror that DB2 gives should point what that may be:

DB2 SQL Error: SQLCODE=-206, SQLSTATE=42703, SQLERRMC=[THE_UNDEFINED_COLUMN_OR_PARAMETER_NAME], DRIVER=4.8.87

Double check your table definition. Maybe you just missed adding something.

I also tried google-ing this problem and saw this:

x$L1 = letters[1:10]
x$L2 = letters[11:20]

cor(x)

I've found the updated answer from this video, the accepted answer didn't work for me.

First clone the latest repo from git (if haven't) using git clone <HTTPs link of the project> (or using SSH) then go to the desire branch using git checkout <branch name> .

Use the command

git log

to check the latest commits. Copy the shal of the particular commit. Then use the command

git fetch origin <Copy paste the shal here>

After pressing enter key. Now use the command

git checkout FETCH_HEAD

Now the particular commit will be available to your local. Change anything and push the code using git push origin <branch name> . That's all. Check the video for reference.

You not only have to put the meta tag, telling that it is UTF-8 but really make the document UTF-8. You can do that with good editors (like notepad++) by converting them to "unicode" or "UTF-8 without BOM". Than you can simply use arabic characters

As this page is UTF-8, here are some examples (I hope I don't write anything rude here): ???

If you use a server side scripting language make sure that it does not output the page in a different encoding. In PHP e.g. you can set it like this:

header('Content-Type: text/html; charset=utf-8');

var q=(from pd in dataContext.tblProducts join od in dataContext.tblOrders on pd.ProductID equals od.ProductID orderby od.OrderID select new { od.OrderID,
 pd.ProductID,
 pd.Name,
 pd.UnitPrice,
 od.Quantity,
 od.Price,
 }).ToList(); 

Possible in IE and chrome although it does not work in firefox:

<script>
   function toggleZoomScreen() {
       document.body.style.zoom = "80%";
   } 
</script>

<img src="example.jpg" alt="example" onclick="toggleZoomScreen()">

Here is the alternative command:

gnuplot -p -e 'plot for [file in system("find . -name \\*.txt -depth 1")] file using 1:2 title file with lines'

Worked for me..

$timestamp = strtotime('10:09') + 60*60;

$time = date('H:i', $timestamp);

echo $time;//11:09

Explanation:

strtotime('10:09') creates a numerical timestamp in seconds, something like 1510450372. Simply add or remove the amount of seconds you need and use date() to convert it back into a human readable format.

$timestamp = strtotime('10:09') + 60*60; // 10:09 + 1 hour
$timestamp = strtotime('10:09') + 60*60*2; // 10:09 + 2 hours
$timestamp = strtotime('10:09') - 60*60; // 10:09 - 1 hour

time() also creates a numerical timestamp but for right now. You can use it in the same way.

$timestamp = time() + 60*60; // now + 1 hour

I'm not sure I like the compiling at link time. However, if you're just replacing the element with another you don't need to do that.

All in all I prefer the first one. Simply set scope to {ngModel:"="} and set ng-model="ngModel" where you want it in your template.

Update: I inlined the code snippet and updated it for Angular v1.2. Turns out that isolate scope is still best, especially when not using jQuery. So it boils down to:

• Are you replacing a single element: Just replace it, leave the scope alone, but note that replace is deprecated for v2.0:

  app.directive('myReplacedDirective', function($compile) {
    return {
      restrict: 'E',
      template: '<input class="some">',
      replace: true
    };
  });
  

• Otherwise use this:

  app.directive('myDirectiveWithScope', function() {
    return {
      restrict: 'E',
      scope: {
        ngModel: '=',
      },
      template: '<div class="some"><input ng-model="ngModel"></div>'
    };
  });
  

var object = {
    key1 : {
        name : 'xxxxxx',
        value : '100.0'
    },
    key2 : {
        name : 'yyyyyyy',
        value : '200.0'
    },
    key3 : {
        name : 'zzzzzz',
        value : '500.0'
    },
}

If thats how your object looks and you want to loop each name and value then I would try and do something like.

$.each(object,function(key,innerjson){
    /*
        key would be key1,key2,key3
        innerjson would be the name and value **
    */

    //Alerts and logging of the variable.
    console.log(innerjson); //should show you the value    
    alert(innerjson.name); //Should say xxxxxx,yyyyyy,zzzzzzz
});

You can use a lambda with an input parameter, like so:

.Returns((string myval) => { return myval; });

Or slightly more readable:

.Returns<string>(x => x);

Process is not runnable by itself. In regard to execution, process is just a container for threads. Meaning you can't pause the process at all. It is simply not applicable to process.

Use jquery cookie https://github.com/carhartl/jquery-cookie and then you can be sure the class will stay on page refresh.

Stores the id of the clicked element in the cookie and then uses that to add the class on refresh.

        //Get cookie value and set active
        var tab = $.cookie('active');
        $('#' + tab).addClass('active');

        //Set cookie active tab value on click
        //Done this way to preserve after page refresh
        $('.topTab').click(function (event) {
            var clickedTab = event.target.id;
            $.removeCookie('active', { path: '/' });
            $( '.active' ).removeClass( 'active' );
            $.cookie('active', clickedTab, { path: '/' });
        });

It would be better to have a check before getting the string.

$newstring = substr($dynamicstring, -7);

if characters are greater then 7 return last 7 characters else return the provided string.

or do this if you need to return message or error if length is less then 7

$newstring = (strlen($dynamicstring)>7)?substr($dynamicstring, -7):"message";

substr documentation

generally, as a File object:

File getCwd() {
  return new File("").getAbsoluteFile();
}

you may want to have full qualified string like "D:/a/b/c" doing:

getCwd().getAbsolutePath()

Here is another real life example that works fine at least with 2008 release (and later).

This is the original query which uses simple max() to get at least one of the values:

SELECT option_name, Field_M3_name, max(Option_value) AS "Option value", max(Sorting) AS "Sorted"
FROM Value_list group by Option_name, Field_M3_name
ORDER BY option_name, Field_M3_name

Improved version, where the main improvement is that we show all values comma separated:

SELECT from1.keys, from1.option_name, from1.Field_M3_name,

 Stuff((SELECT DISTINCT ', ' + [Option_value] FROM Value_list from2
  WHERE COALESCE(from2.Option_name,'') + '|' + COALESCE(from2.Field_M3_name,'') = from1.keys FOR XML PATH(''),TYPE)
  .value('text()[1]','nvarchar(max)'),1,2,N'') AS "Option values",

 Stuff((SELECT DISTINCT ', ' + CAST([Sorting] AS VARCHAR) FROM Value_list from2
  WHERE COALESCE(from2.Option_name,'') + '|' + COALESCE(from2.Field_M3_name,'') = from1.keys FOR XML PATH(''),TYPE)
  .value('text()[1]','nvarchar(max)'),1,2,N'') AS "Sorting"

FROM ((SELECT DISTINCT COALESCE(Option_name,'') + '|' + COALESCE(Field_M3_name,'') AS keys, Option_name, Field_M3_name FROM Value_list)
-- WHERE
) from1
ORDER BY keys

Note that we have solved all possible NULL case issues that I can think of and also we fixed an error that we got for numeric values (field Sorting).

All procedure at once. Based on @Till Schäfer answer.

Thanks!

NOTE: Works to OpenJDK!

FURTHER QUESTION: Wrong information?

If you check memory usage with the ps command, you will see that the java process consumes much more...

ps -eo size,pid,user,command --sort -size | egrep -i "*/bin/java *" | egrep -v grep | awk '{ hr=$1/1024 ; printf("%.2f MB ",hr) } { for ( x=4 ; x<=NF ; x++ ) { printf("%s ",$x) } print "" }' | cut -d "" -f2 | cut -d "-" -f1

UPDATE (2021-02-16):

According to the reference below (and @Till Schäfer comment) "ps can show total reserved memory from OS" (adapted) and "jstat can show used space of heap and stack" (adapted). So, we see a difference between what is pointed out by the ps command and the jstat command.

According to our understanding, the most "realistic" information would be the ps output since we will have an effective response of how much of the system's memory is compromised. The command jstat serves for a more detailed analysis regarding the java performance in the consumption of reserved memory from OS.

[Ref.: http://www.openkb.info/2014/06/how-to-check-java-memory-usage.html ]

You can do it like this:

postData[postData.length] = { name: "variable_name", value: variable_value };

Download and include this plugin

<script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.2/rollups/md5.js"></script>

and use like

if(CryptoJS.MD5($("#txtOldPassword").val())) != oldPassword) {

}

//Following lines shows md5 value
//var hash = CryptoJS.MD5("Message");
//alert(hash);

From the menu bar: Project -> Properties -> Java Compiler

Enable project specific settings (checked) Uncheck "use Compliance from execution environment '.... Select the desired "compiler compliance level"

That will allow you to compile "1.5" code using a "1.6" JDK.

If you want to acutally use a 1.5 JDK to produce "1.5" compliant code, then install a suitable 1.5 JDK and tell eclipse where it is installed via:

Window -> preferences -> Installed JREs

And then go back to your project

Project -> properties -> Java Build Path -> libraries

remove the 1.6 system libaries, and: add library... -> JRE System LIbrary -> Alternate JRE -> The JRE you want.

Verify that the correct JRE is on the project's build path, save everything, and enjoy!

Put it in the init() function for your plugin.

function your_namespace() {
    wp_register_style('your_namespace', plugins_url('style.css',__FILE__ ));
    wp_enqueue_style('your_namespace');
    wp_register_script( 'your_namespace', plugins_url('your_script.js',__FILE__ ));
    wp_enqueue_script('your_namespace');
}

add_action( 'admin_init','your_namespace');

It took me also some time before I found the (for me) best solution which is foolproof imho.

Cheers

@Franci Penov - modify is possible in the sense of overwrite with /f, eg

reg add "HKCU\Software\etc\etc" /f /v "value" /t REG_SZ /d "Yes"

There are a couple of ways by which you can access variables or objects in other classes or Activity.

A. Database

B. Shared preferences.

C. Object serialization.

D. A class which can hold common data can be named as Common Utilities. It depends on you.

E. Passing data through Intents and Parcelable Interface.

It depends upon your project needs.

A. Database

SQLite is an open source database which is embedded into Android. SQLite supports standard relational database features like SQL syntax, transactions and prepared statements.

Tutorials

B. Shared preferences

Suppose you want to store username. So there will now be two things, a key username, value value.

How to store

 // Create object of SharedPreferences.
 SharedPreferences sharedPref = PreferenceManager.getDefaultSharedPreferences(this);

 //Now get Editor
 SharedPreferences.Editor editor = sharedPref.edit();

 //Put your value
 editor.putString("userName", "stackoverlow");

 //Commits your edits
 editor.commit();

Using putString(), putBoolean(), putInt(), putFloat(), and putLong() you can save your desired dtatype.

How to fetch

SharedPreferences sharedPref = PreferenceManager.getDefaultSharedPreferences(this);
String userName = sharedPref.getString("userName", "Not Available");

http://developer.android.com/reference/android/content/SharedPreferences.html

C. Object serialization

Object serlization is used if we want to save an object state to send it over a network or you can use it for your purpose also.

Use Java beans and store in it as one of his fields and use getters and setter for that.

JavaBeans are Java classes that have properties. Think of properties as private instance variables. Since they're private, the only way they can be accessed from outside of their class is through methods in the class. The methods that change a property's value are called setter methods, and the methods that retrieve a property's value are called getter methods.

public class VariableStorage implements Serializable  {

    private String inString;

    public String getInString() {
        return inString;
    }

    public void setInString(String inString) {
        this.inString = inString;
    }
}

Set the variable in your mail method by using

VariableStorage variableStorage = new VariableStorage();
variableStorage.setInString(inString);

Then use object serialzation to serialize this object and in your other class deserialize this object.

In serialization an object can be represented as a sequence of bytes that includes the object's data as well as information about the object's type and the types of data stored in the object.

After a serialized object has been written into a file, it can be read from the file and deserialized. That is, the type information and bytes that represent the object and its data can be used to recreate the object in memory.

If you want tutorial for this refer to:

• Serialization in Java (blog post)

• Get variable in other classes (Stack Overflow)

D. CommonUtilities

You can make a class by yourself which can contain common data which you frequently need in your project.

Sample

public class CommonUtilities {

    public static String className = "CommonUtilities";

}

E. Passing data through intents

Please refer the tutorial Android – Parcel data to pass between Activities using Parcelable classes for this option of passing data.

The accepted convention of passing C-strings to functions is to use a pointer:

void function(char* name)

When the function modifies the string you should also pass in the length:

void function(char* name, size_t name_length)

Your first example:

char *functionname(char *string name[256])

passes an array of pointers to strings which is not what you need at all.

Your second example:

char functionname(char string[256])

passes an array of chars. The size of the array here doesn't matter and the parameter will decay to a pointer anyway, so this is equivalent to:

char functionname(char *string)

See also this question for more details on array arguments in C.

For several cases, or even just a few cases involving a lot of criteria, consider using a switch.

switch( true ){

    case ( !empty($youtube) && !empty($link) ):{
        // Nothing is empty...
        break;
    }

    case ( !empty($youtube) && empty($link) ):{
        // One is empty...
        break;
    }

    case ( empty($youtube) && !empty($link) ):{
        // The other is empty...
        break;
    }

    case ( empty($youtube) && empty($link) ):{
        // Everything is empty
        break;
    }

    default:{
        // Even if you don't expect ever to use it, it's a good idea to ALWAYS have a default.
        // That way if you change it, or miss a case, you have some default handler.
        break;

If you have multiple cases that require the same action, you can stack them and omit the break; to flowthrough. Just maybe put a comment like /*Flowing through*/ so you're explicit about doing it on purpose.

Note that the { } around the cases aren't required, but they are nice for readability and code folding.

Here's the example from my code. So I will read a text from 1st line to 3rd line using readLine() and then store to array variable and print into textfield using for-loop :

QFile file("file.txt");

    if(!file.open(QIODevice::ReadOnly | QIODevice::Text))
        return;

    QTextStream in(&file);
    QString line[3] = in.readLine();
    for(int i=0; i<3; i++)
    {
        ui->textEdit->append(line[i]);
    }

While I tried the approach above, it becomes a complete disaster with mvc. Your controller passing a model and your view using a strongly typed model become too difficult to work with.

Get your Dataset into a List ..... I have a repository pattern and here is an example of getting a dataset from an old school asmx web service private readonly CISOnlineSRVDEV.ServiceSoapClient _ServiceSoapClient;

    public Get_Client_Repository()
        : this(new CISOnlineSRVDEV.ServiceSoapClient())
    {

    }
    public Get_Client_Repository(CISOnlineSRVDEV.ServiceSoapClient serviceSoapClient)
    {
        _ServiceSoapClient = serviceSoapClient;
    }


    public IEnumerable<IClient> GetClient(IClient client)
    {
        // ****  Calling teh web service with passing in the clientId and returning a dataset
        DataSet dataSet = _ServiceSoapClient.get_clients(client.RbhaId,
                                                        client.ClientId,
                                                        client.AhcccsId,
                                                        client.LastName,
                                                        client.FirstName,
                                                        "");//client.BirthDate.ToString());  //TODO: NEED TO FIX

        // USE LINQ to go through the dataset to make it easily available for the Model to display on the View page
        List<IClient> clients = (from c in dataSet.Tables[0].AsEnumerable()
                                 select new Client()
                                 {
                                     RbhaId = c[5].ToString(),
                                     ClientId = c[2].ToString(),
                                     AhcccsId = c[6].ToString(),
                                     LastName = c[0].ToString(), // Add another field called   Sex M/F  c[4]
                                     FirstName = c[1].ToString(),
                                     BirthDate = c[3].ToDateTime()  //extension helper  ToDateTime()
                                 }).ToList<IClient>();

        return clients;

    }

Then in the Controller I'm doing this

IClient client = (IClient)TempData["Client"];

// Instantiate and instance of the repository 
var repository = new Get_Client_Repository();
// Set a model object to return the dynamic list from repository method call passing in the parameter data
var model = repository.GetClient(client);

// Call the View up passing in the data from the list
return View(model);

Then in the View it is easy :

@model IEnumerable<CISOnlineMVC.DAL.IClient>

@{
    ViewBag.Title = "CLIENT ALL INFORMATION";
}

<h2>CLIENT ALL INFORMATION</h2>

<table>
    <tr>
        <th></th>
        <th>Last Name</th>
        <th>First Name</th>
        <th>Client ID</th>
        <th>DOB</th>
        <th>Gender</th>
        <th>RBHA ID</th>
        <th>AHCCCS ID</th>
    </tr>

@foreach (var item in Model) {
    <tr>
        <td>
            @Html.ActionLink("Select", "ClientDetails", "Cis", new { id = item.ClientId }, null) |
        </td>
        <td>
            @item.LastName
        </td>
        <td>
            @item.FirstName
        </td>
         <td>
            @item.ClientId
        </td>
         <td>
            @item.BirthDate

         <td>

        </td>
         <td>
            @item.RbhaId
        </td>
         <td>
            @item.AhcccsId
        </td>
    </tr>
}

Let's make it simple as hell. If you want a single number for the number of dimensions like 2, 3, 4, etc., then just use tf.rank(). But, if you want the exact shape of the tensor then use tensor.get_shape()

with tf.Session() as sess:
   arr = tf.random_normal(shape=(10, 32, 32, 128))
   a = tf.random_gamma(shape=(3, 3, 1), alpha=0.1)
   print(sess.run([tf.rank(arr), tf.rank(a)]))
   print(arr.get_shape(), ", ", a.get_shape())     


# for tf.rank()    
[4, 3]

# for tf.get_shape()
Output: (10, 32, 32, 128) , (3, 3, 1)

public IEnumerable<Friend> FindFriends()
{
    return userExists ? doc.Descendants("user").Select(user => new Friend
        {
            ID = user.Element("id").Value,
            Name = user.Element("name").Value,
            URL = user.Element("url").Value,
            Photo = user.Element("photo").Value
        }): new List<Friend>();
}

Outline

Here are the steps to follow.

• Read the picture as a BufferedImage.
• Resize the BufferedImage to another BufferedImage that's the size of the JLabel.
• Create an ImageIcon from the resized BufferedImage.

You do not have to set the preferred size of the JLabel. Once you've scaled the image to the size you want, the JLabel will take the size of the ImageIcon.

Read the picture as a BufferedImage

BufferedImage img = null;
try {
    img = ImageIO.read(new File("strawberry.jpg"));
} catch (IOException e) {
    e.printStackTrace();
}

Resize the BufferedImage

Image dimg = img.getScaledInstance(label.getWidth(), label.getHeight(),
        Image.SCALE_SMOOTH);

Make sure that the label width and height are the same proportions as the original image width and height. In other words, if the picture is 600 x 900 pixels, scale to 100 X 150. Otherwise, your picture will be distorted.

Create an ImageIcon

ImageIcon imageIcon = new ImageIcon(dimg);

Here is how to do dump the database (with just the schema):

mysqldump -u root -p"passwd" --no-data --add-drop-database --databases my_db_name | sed 's#/[*]!40000 DROP DATABASE IF EXISTS my_db_name;#' >my_db_name.sql

If you also want the data, remove the --no-data option.

I organize packages by feature, not by patterns or implementation roles. I think packages like:

• beans
• factories
• collections

are wrong.

I prefer, for example:

• orders
• store
• reports

so I can hide implementation details through package visibility. Factory of orders should be in the orders package so details about how to create an order are hidden.

UTF-8 without BOM has no BOM, which doesn't make it any better than UTF-8 with BOM, except when the consumer of the file needs to know (or would benefit from knowing) whether the file is UTF-8-encoded or not.

The BOM is usually useful to determine the endianness of the encoding, which is not required for most use cases.

Also, the BOM can be unnecessary noise/pain for those consumers that don't know or care about it, and can result in user confusion.

It is the SQL extension called analytics. The "over" in the select statement tells oracle that the function is a analytical function, not a group by function. The advantage to using analytics is that you can collect sums, counts, and a lot more with just one pass through of the data instead of looping through the data with sub selects or worse, PL/SQL.

It does look confusing at first but this will be second nature quickly. No one explains it better then Tom Kyte. So the link above is great.

Of course, reading the documentation is a must.

Number((6.688689).toFixed(1)); // 6.7

var number = 6.688689;
var roundedNumber = Math.round(number * 10) / 10;

Use toFixed() function.

(6.688689).toFixed(); // equal to "7"
(6.688689).toFixed(1); // equal to "6.7"
(6.688689).toFixed(2); // equal to "6.69"

The comment in your code is wrong. INADDR_ANY doesn't put server's IP automatically'. It essentially puts 0.0.0.0, for the reasons explained in mark4o's answer.

To enable ssh access from the Internet for instances in a VPC subnet do the following:

• Attach an Internet gateway to your VPC.
• Ensure that your subnet's route table points to the Internet gateway.
• Ensure that instances in your subnet have a globally unique IP address (public IPv4 address, Elastic IP address, or IPv6 address).
• Ensure that your network access control (at VPC Level) and security group rules (at ec2 level) allow the relevant traffic to flow to and from your instance. Ensure your network Public IP address is enabled for both. By default, Network AcL allow all inbound and outbound traffic except explicitly configured otherwise

Make sure you've set your locale settings right before running the script from the shell, e.g.

$ locale -a | grep "^en_.\+UTF-8"
en_GB.UTF-8
en_US.UTF-8
$ export LC_ALL=en_GB.UTF-8
$ export LANG=en_GB.UTF-8

Docs: man locale, man setlocale.

Many description internet-wide don't mention that specifying Access-Control-Allow-Origin is not enough. Here is a complete example that works for me:

<?php
    if ($_SERVER['REQUEST_METHOD'] === 'OPTIONS') {
        header('Access-Control-Allow-Origin: *');
        header('Access-Control-Allow-Methods: POST, GET, DELETE, PUT, PATCH, OPTIONS');
        header('Access-Control-Allow-Headers: token, Content-Type');
        header('Access-Control-Max-Age: 1728000');
        header('Content-Length: 0');
        header('Content-Type: text/plain');
        die();
    }

    header('Access-Control-Allow-Origin: *');
    header('Content-Type: application/json');

    $ret = [
        'result' => 'OK',
    ];
    print json_encode($ret);

You don't have to write all that code. AngularJS will keep the model and the checkboxes in sync simply by using ngTrueValue and ngFalseValue

Codepen here: http://codepen.io/paulbhartzog/pen/kBhzn

Code snippet:

<p ng-repeat="item in list1" class="item" id="{{item.id}}">
  <strong>{{item.id}}</strong> <input name='obj1_data' type="checkbox" ng-model="list1[$index].data" ng-true-value="1" ng-false-value="0"> Click this to change data value below
</p>
<pre>{{list1 | json}}</pre>

The variable name you're looking for is ansible_ssh_private_key_file.

You should set it at 'vars' level:

• in the inventory file:

  myHost ansible_ssh_private_key_file=~/.ssh/mykey1.pem
  myOtherHost ansible_ssh_private_key_file=~/.ssh/mykey2.pem
  

• in the host_vars:

  # hosts_vars/myHost.yml
  ansible_ssh_private_key_file: ~/.ssh/mykey1.pem
  
  # hosts_vars/myOtherHost.yml
  ansible_ssh_private_key_file: ~/.ssh/mykey2.pem
  

• in a group_vars file if you use the same key for a group of hosts

• in the vars section of your play:

  - hosts: myHost
    remote_user: ubuntu
    vars_files:
      - vars.yml
    vars:
      ansible_ssh_private_key_file: "{{ key1 }}"
    tasks:
      - name: Echo a hello message
        command: echo hello
  

Inventory documentation

table {
    border-collapse: collapse;

.simulate() doesn't work for me somehow, I got it working with just accessing the node.value without needing to call .simulate(); in your case:

const wrapper = mount(<EditableText defaultValue="Hello" />);
const input = wrapper.find('input').at(0);

// Get the value
console.log(input.node.value); // Hello

// Set the value
input.node.value = 'new value';

// Get the value
console.log(input.node.value); // new value

Hope this helps for others!

The problem with your desired output is that it is not valid json document,; it's a stream of json documents!

That's okay, if its what you need, but that means that for each document you want in your output, you'll have to call json.dumps.

Since the newline you want separating your documents is not contained in those documents, you're on the hook for supplying it yourself. So we just need to pull the loop out of the call to json.dump and interpose newlines for each document written.

import csv
import json

csvfile = open('file.csv', 'r')
jsonfile = open('file.json', 'w')

fieldnames = ("FirstName","LastName","IDNumber","Message")
reader = csv.DictReader( csvfile, fieldnames)
for row in reader:
    json.dump(row, jsonfile)
    jsonfile.write('\n')

Just use:

overflow: hidden;
white-space: nowrap;

Return the address of the thing pointed to by the iterator:

&(*iterator)

Edit: To clear up some confusion:

vector <int> vec;          // a global vector of ints

void f() {
   vec.push_back( 1 );    // add to the global vector
   vector <int>::iterator it = vec.begin();
   * it = 2;              // change what was 1 to 2
   int * p = &(*it);      // get pointer to first element
   * p = 3;               // change what was 2 to 3
}

No need for vectors of pointers or dynamic allocation.

Solution 1:

Extract P12 from jks

keytool -importkeystore -srckeystore MyRootCA.jks -destkeystore MyRootCA.p12 -deststoretype PKCS12

Extract PEM from P12 and Edit file and pem from crt file

openssl pkcs12 -in MyRootCA.p12 -clcerts -nokeys -out MyRootCA.crt

Extract key from jks

openssl pkcs12 -in MyRootCA.p12 -nocerts -out encryptedPrivateKey.pem
openssl rsa -in encryptedPrivateKey.pem -out decryptedPrivateKey.key

Solution 2:

Extract PEM and encryptedPrivateKey to txt file```

openssl pkcs12 -in MyRootCA.p12 -out keys_out.txt

Decrypt privateKey

openssl rsa -in encryptedPrivateKey.key [-outform PEM] -out decryptedPrivateKey.key

I know that this question is a little old, but I thought that I would provide an alternative which, in my opinion, might be a little easier. If you're willing to add "temporary" columns to a data set, you can use Excel's Analysis ToolPak?Data Analysis?Regression. The secret to doing a quadratic or a cubic regression analysis is defining the Input X Range:.

If you're doing a simple linear regression, all you need are 2 columns, X & Y. If you're doing a quadratic, you'll need X_1, X_2, & Y where X_1 is the x variable and X_2 is x^2; likewise, if you're doing a cubic, you'll need X_1, X_2, X_3, & Y where X_1 is the x variable, X_2 is x^2 and X_3 is x^3. Notice how the Input X Range is from A1 to B22, spanning 2 columns.

The following image the output of the regression analysis. I've highlighted the common outputs, including the R-Squared values and all the coefficients.

1. Why is this happening?

   The entire ext/mysql PHP extension, which provides all functions named with the prefix mysql_, was officially deprecated in PHP v5.5.0 and removed in PHP v7.

   It was originally introduced in PHP v2.0 (November 1997) for MySQL v3.20, and no new features have been added since 2006. Coupled with the lack of new features are difficulties in maintaining such old code amidst complex security vulnerabilities.

   The manual has contained warnings against its use in new code since June 2011.

2. How can I fix it?

   As the error message suggests, there are two other MySQL extensions that you can consider: MySQLi and PDO_MySQL, either of which can be used instead of ext/mysql. Both have been in PHP core since v5.0, so if you're using a version that is throwing these deprecation errors then you can almost certainly just start using them right away—i.e. without any installation effort.

   They differ slightly, but offer a number of advantages over the old extension including API support for transactions, stored procedures and prepared statements (thereby providing the best way to defeat SQL injection attacks). PHP developer Ulf Wendel has written a thorough comparison of the features.

   Hashphp.org has an excellent tutorial on migrating from ext/mysql to PDO.

3. I understand that it's possible to suppress deprecation errors by setting error_reporting in php.ini to exclude E_DEPRECATED:

   error_reporting = E_ALL ^ E_DEPRECATED
   

   What will happen if I do that?

   Yes, it is possible to suppress such error messages and continue using the old ext/mysql extension for the time being. But you really shouldn't do this—this is a final warning from the developers that the extension may not be bundled with future versions of PHP (indeed, as already mentioned, it has been removed from PHP v7). Instead, you should take this opportunity to migrate your application now, before it's too late.

   Note also that this technique will suppress all E_DEPRECATED messages, not just those to do with the ext/mysql extension: therefore you may be unaware of other upcoming changes to PHP that would affect your application code. It is, of course, possible to only suppress errors that arise on the expression at issue by using PHP's error control operator—i.e. prepending the relevant line with @—however this will suppress all errors raised by that expression, not just E_DEPRECATED ones.

What should you do?

• You are starting a new project.

  There is absolutely no reason to use ext/mysql—choose one of the other, more modern, extensions instead and reap the rewards of the benefits they offer.

• You have (your own) legacy codebase that currently depends upon ext/mysql.

  It would be wise to perform regression testing: you really shouldn't be changing anything (especially upgrading PHP) until you have identified all of the potential areas of impact, planned around each of them and then thoroughly tested your solution in a staging environment.

  • Following good coding practice, your application was developed in a loosely integrated/modular fashion and the database access methods are all self-contained in one place that can easily be swapped out for one of the new extensions.

    Spend half an hour rewriting this module to use one of the other, more modern, extensions; test thoroughly. You can later introduce further refinements to reap the rewards of the benefits they offer.

  • The database access methods are scattered all over the place and cannot easily be swapped out for one of the new extensions.

    Consider whether you really need to upgrade to PHP v5.5 at this time.

    You should begin planning to replace ext/mysql with one of the other, more modern, extensions in order that you can reap the rewards of the benefits they offer; you might also use it as an opportunity to refactor your database access methods into a more modular structure.

    However, if you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

• You are using a third party project that depends upon ext/mysql.

  Consider whether you really need to upgrade to PHP v5.5 at this time.

  Check whether the developer has released any fixes, workarounds or guidance in relation to this specific issue; or, if not, pressure them to do so by bringing this matter to their attention. If you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

  It is absolutely essential to perform regression testing.

You can do it with something like this, so if no arguments are specified it will continue anyway:

public static void main(String[] args) {
    try {
        String one = args[0];
        String two = args[1];
    }
    catch (ArrayIndexOutOfBoundsException e){
        System.out.println("ArrayIndexOutOfBoundsException caught");
    }
    finally {

    }
}

And then launch the application:

java -jar myapp.jar arg1 arg2

By using this way its possible to create a different implementation for different types (i.e. Int or custom classes like CurrencyUnit, ...). Its also possible to scan for this method invoke using the genstrings utility. Simply add the routine flag to the command

genstrings MyCoolApp/Views/SomeView.swift -s localize -o .

extension:

import UIKit

extension String {
    public static func localize(key: String, comment: String) -> String {
        return NSLocalizedString(key, comment: comment)
    }
}

usage:

String.localize("foo.bar", comment: "Foo Bar Comment :)")

In iOS 9 it works again!

To open Settings > General > Keyboard, I use:

prefs:root=General&path=Keyboard

Moreover, it is possible to go farther to Keyboards:

prefs:root=General&path=Keyboard/KEYBOARDS

Using <summary> and <details>

Using <summary> and <details> elements is the simplest but see browser support as current IE is not supporting it. You can polyfill though (most are jQuery-based). Do note that unsupported browser will simply show the expanded version of course, so that may be acceptable in some cases.

/* Optional styling */_x000D_
summary::-webkit-details-marker {_x000D_
  color: blue;_x000D_
}_x000D_
summary:focus {_x000D_
  outline-style: none;_x000D_
}

<details>_x000D_
  <summary>Summary, caption, or legend for the content</summary>_x000D_
  Content goes here._x000D_
</details>

See also how to style the <details> element (HTML5 Doctor) (little bit tricky).

Pure CSS3

The :target selector has a pretty good browser support, and it can be used to make a single collapsible element within the frame.

.details,_x000D_
.show,_x000D_
.hide:target {_x000D_
  display: none;_x000D_

To prevent the flex items from shrinking, set the flex shrink factor to 0:

The flex shrink factor determines how much the flex item will shrink relative to the rest of the flex items in the flex container when negative free space is distributed. When omitted, it is set to 1.

Besides the redundant ) this expression will always be true because currentStatus will always match one of these two conditions:

currentStatus !== 'open' || currentStatus !== 'reopen'

perhaps you mean one of

!(currentStatus === 'open' || currentStatus === 'reopen')
(currentStatus !== 'open' && currentStatus !== 'reopen')

You can find it inside the /config folder.

When you eject you get a message like:

 Adding /config/webpack.config.dev.js to the project
 Adding /config/webpack.config.prod.js to the project

By default, the layouts in /res/layout are applied to both portrait and landscape.

If you have for example

/res/layout/main.xml

you can add a new folder /res/layout-land, copy main.xml into it and make the needed adjustments.

HTTP status code 500 usually means that the webserver code has crashed. You need to determine the status code beforehand using HttpURLConnection#getResponseCode() and in case of errors, read the HttpURLConnection#getErrorStream() instead. It may namely contain information about the problem.

If the host has blocked you, you would rather have gotten a 4nn status code like 401 or 403.

Didn't work with ODBC-Bridge for me too. I got the way around to initialize ODBC connection using ODBC driver.

 import java.sql.*;  
 public class UserLogin

     public static void main(String[] args)
     {
        try
        {    
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

            // C:\\databaseFileName.accdb" - location of your database 
           String url = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=" + "C:\\emp.accdb";

            // specify url, username, pasword - make sure these are valid 
            Connection conn = DriverManager.getConnection(url, "username", "password");

            System.out.println("Connection Succesfull");
         } 
         catch (Exception e) 
         {
            System.err.println("Got an exception! ");
            System.err.println(e.getMessage());

          }
      }
  }

Here I can't see even a single correct answer for this question (in WinForms tag) and it's strange for such frequent question.

Items of a ListBox control may be DataRowView, Complex Objects, Anonymous types, primary types and other types. Underlying value of an item should be calculated base on ValueMember.

ListBox control has a GetItemText which helps you to get the item text regardless of the type of object you added as item. It really needs such GetItemValue method.

GetItemValue Extension Method

We can create GetItemValue Extension Method to get item value which works like GetItemText:

using System;
using System.Windows.Forms;
using System.ComponentModel;
public static class ListControlExtensions
{
    public static object GetItemValue(this ListControl list, object item)
    {
        if (item == null)
            throw new ArgumentNullException("item");

        if (string.IsNullOrEmpty(list.ValueMember))
            return item;

        var property = TypeDescriptor.GetProperties(item)[list.ValueMember];
        if (property == null)
            throw new ArgumentException(
                string.Format("item doesn't contain '{0}' property or column.",
                list.ValueMember));
        return property.GetValue(item);
    }
}

Using above method you don't need to worry about settings of ListBox and it will return expected Value for an item. It works with List<T>, Array, ArrayList, DataTable, List of Anonymous Types, list of primary types and all other lists which you can use as data source. Here is an example of usage:

//Gets underlying value at index 2 based on settings
this.listBox1.GetItemValue(this.listBox1.Items[2]);

Since we created the GetItemValue method as an extension method, when you want to use the method, don't forget to include the namespace which you put the class in.

This method is applicable on ComboBox and CheckedListBox too.

import re
for i in range(len(myDict.values())):
    for j in range(len(myDict.values()[i])):
         match=re.search(r'Mary', myDict.values()[i][j])
         if match:
                 print match.group() #Mary
                 print myDict.keys()[i] #firstName
                 print myDict.values()[i][j] #Mary-Ann

int [] newArray = new int[old1.length+old2.length];
System.arraycopy( old1, 0, newArray, 0, old1.length);
System.arraycopy( old2, 0, newArray, old1.length, old2.length );

Don't use element-by-element copying, it's very slow compared to System.arraycopy()

Just a little addition to the answer of @dAm2k :

I've done a sudo apt-get remove --purge mariadb\*.

I seems that in the new release of debian (stretch), when you install mysql it install mariadb package with it.

Hope it helps.

If you don't care about the icon looking pretty on all sort of Apple devices, just add

get '/:apple_touch_icon' => redirect('/icon.png'), constraints: { apple_touch_icon: /apple-touch-icon(-\d+x\d+)?(-precomposed)?\.png/ }

to your config/routes.rb file and some icon.png to your public directory. Redirecting to 404.html instead of icon.png works too.

You're using the declarative style of specifying your pipeline, so you must not use try/catch blocks (which are for Scripted Pipelines), but the post section. See: https://jenkins.io/doc/book/pipeline/syntax/#post-conditions

This code works both in Eclipse and in Exported Runnable JAR

    // Java: In caso di JAR dentro il JAR applicativo 
    URLClassLoader urlClassLoader = (URLClassLoader)Cypher.class.getClassLoader();
    URL url = urlClassLoader.findResource(resourceName);
    if (url != null) {
        URLConnection conn = url.openConnection();
        if (conn != null) {
            resourceStream = conn.getInputStream();
        }
    }
    
    if (resourceStream != null) {
        Files.copy(resourceStream, outFile.toPath(), StandardCopyOption.REPLACE_EXISTING);
        return outFile.getAbsolutePath();
    } else {
        System.out.println("Embedded Resource " + resourceName + " not found.");
    }
    
    return "";

 }

resolved the issue

You could use:

 if(!this.form.checkbox.checked)
{
    alert('You must agree to the terms first.');
    return false;
}

(demo page).

<input type="checkbox" name="checkbox" value="check"  />
<input type="submit" name="email_submit" value="submit" onclick="if(!this.form.checkbox.checked){alert('You must agree to the terms first.');return false}"  />

• Returning false from an inline event handler will prevent the default action from taking place (in this case, submitting the form).
• ! is the Boolean NOT operator.
• this is the submit button because it is the element the event handler is attached to.
• .form is the form the submit button is in.
• .checkbox is the control named "checkbox" in that form.
• .checked is true if the checkbox is checked and false if the checkbox is unchecked.

The following works from me:

i = '0'
while len(i) != 0:
    i = list(map(int, input(),split()))

The following works if you have something like this in your app.js:

http.createServer(app).listen(app.get('port'),
  function(){
    console.log("Express server listening on port " + app.get('port'));
});

Either explicitly hardcode your code to use the port you want, like:

app.set('port', process.env.PORT || 3000);

This code means set your port to the environment variable PORT or if that is undefined then set it to the literal 3000.

Or, use your environment to set the port. Setting it via the environment is used to help delineate between PRODUCTION and DEVELOPMENT and also a lot of Platforms as a Service use the environment to set the port according to their specs as well as internal Express configs. The following sets an environment key=value pair and then launches your app.

$ PORT=8080 node app.js

In reference to your code example, you want something like this:

var express = require("express");
var app = express();

// sets port 8080 to default or unless otherwise specified in the environment
app.set('port', process.env.PORT || 8080);

app.get('/', function(req, res){
    res.send('hello world');
});

// Only works on 3000 regardless of what I set environment port to or how I set
// [value] in app.set('port', [value]).
// app.listen(3000);
app.listen(app.get('port'));

There are two situations:

It is possible that an object is [NSNull null], or it is impossible.
Your application usually shouldn't use [NSNull null]; you only use it if you want to put a "null" object into an array, or use it as a dictionary value. And then you should know which arrays or dictionaries might contain null values, and which might not.
If you think that an array never contains [NSNull null] values, then don't check for it. If there is an [NSNull null], you might get an exception but that is fine: Objective-C exceptions indicate programming errors. And you have a programming error that needs fixing by changing some code.

If an object could be [NSNull null], then you check for this quite simply by testing
(object == [NSNull null]). Calling isEqual or checking the class of the object is nonsense. There is only one [NSNull null] object, and the plain old C operator checks for it just fine in the most straightforward and most efficient way.

If you check an NSString object that cannot be [NSNull null] (because you know it cannot be [NSNull null] or because you just checked that it is different from [NSNull null], then you need to ask yourself how you want to treat an empty string, that is one with length 0. If you treat it is a null string like nil, then test (object.length == 0). object.length will return 0 if object == nil, so this test covers nil objects and strings with length 0. If you treat a string of length 0 different from a nil string, just check if object == nil.

Finally, if you want to add a string to an array or a dictionary, and the string could be nil, you have the choice of not adding it, replacing it with @"", or replacing it with [NSNull null]. Replacing it with @"" means you lose the ability to distinguish between "no string" and "string of length 0". Replacing it with [NSNull null] means you have to write code when you access the array or dictionary that checks for [NSNull null] objects.

Surprisingly this question doesn't have a definitive documented answer. Perhaps another data point would provide value to others looking for an answer. On my systems running CentOS (6.8,7.3) and Java 8 (build 1.8.0_60-b27, 64-Bit Server):

default memory is 1/4 of physical memory, not limited by 1GB.

Also, -XX:+PrintFlagsFinal prints to STDERR so command to determine current default memory presented by others above should be tweaked to the following:

java -XX:+PrintFlagsFinal 2>&1 | grep MaxHeapSize

The following is returned on system with 64GB of physical RAM:

uintx MaxHeapSize                                  := 16873684992      {product}

As @Agam said,

You need this statement in your driver file: from AthleteList import AtheleteList

From further research, I've found:

http://dev.mysql.com/doc/refman/5.1/en/news-5-1-11.html

Security Fix:

An SQL-injection security hole has been found in multi-byte encoding processing. The bug was in the server, incorrectly parsing the string escaped with the mysql_real_escape_string() C API function.

This vulnerability was discovered and reported by Josh Berkus and Tom Lane as part of the inter-project security collaboration of the OSDB consortium. For more information about SQL injection, please see the following text.

Discussion. An SQL injection security hole has been found in multi-byte encoding processing. An SQL injection security hole can include a situation whereby when a user supplied data to be inserted into a database, the user might inject SQL statements into the data that the server will execute. With regards to this vulnerability, when character set-unaware escaping is used (for example, addslashes() in PHP), it is possible to bypass the escaping in some multi-byte character sets (for example, SJIS, BIG5 and GBK). As a result, a function such as addslashes() is not able to prevent SQL-injection attacks. It is impossible to fix this on the server side. The best solution is for applications to use character set-aware escaping offered by a function such mysql_real_escape_string().

However, a bug was detected in how the MySQL server parses the output of mysql_real_escape_string(). As a result, even when the character set-aware function mysql_real_escape_string() was used, SQL injection was possible. This bug has been fixed.

Workarounds. If you are unable to upgrade MySQL to a version that includes the fix for the bug in mysql_real_escape_string() parsing, but run MySQL 5.0.1 or higher, you can use the NO_BACKSLASH_ESCAPES SQL mode as a workaround. (This mode was introduced in MySQL 5.0.1.) NO_BACKSLASH_ESCAPES enables an SQL standard compatibility mode, where backslash is not considered a special character. The result will be that queries will fail.

To set this mode for the current connection, enter the following SQL statement:

SET sql_mode='NO_BACKSLASH_ESCAPES';

You can also set the mode globally for all clients:

SET GLOBAL sql_mode='NO_BACKSLASH_ESCAPES';

This SQL mode also can be enabled automatically when the server starts by using the command-line option --sql-mode=NO_BACKSLASH_ESCAPES or by setting sql-mode=NO_BACKSLASH_ESCAPES in the server option file (for example, my.cnf or my.ini, depending on your system). (Bug#8378, CVE-2006-2753)

See also Bug#8303.

unsafe.park is pretty much the same as thread.wait, except that it's using architecture specific code (thus the reason it's 'unsafe'). unsafe is not made available publicly, but is used within java internal libraries where architecture specific code would offer significant optimization benefits. It's used a lot for thread pooling.

So, to answer your question, all the thread is doing is waiting for something, it's not really using any CPU. Considering that your original stack trace shows that you're using a lock I would assume a deadlock is going on in your case.

Yes I know you have almost certainly already solved this issue by now. However, you're one of the top results if someone googles sun.misc.unsafe.park. I figure answering the question may help others trying to understand what this method that seems to be using all their CPU is.

I am assuming from context and the tags you used that you are writing a .NET C# app. In this case, you can subscribe to the text changed event, and validate each key stroke.

private void textBox1_TextChanged(object sender, EventArgs e)
{
    if (System.Text.RegularExpressions.Regex.IsMatch(textBox1.Text, "[^0-9]"))
    {
        MessageBox.Show("Please enter only numbers.");
        textBox1.Text = textBox1.Text.Remove(textBox1.Text.Length - 1);
    }
}

RUN and ENTRYPOINT are two different ways to execute a script.

RUN means it creates an intermediate container, runs the script and freeze the new state of that container in a new intermediate image. The script won't be run after that: your final image is supposed to reflect the result of that script.

ENTRYPOINT means your image (which has not executed the script yet) will create a container, and runs that script.

In both cases, the script needs to be added, and a RUN chmod +x /bootstrap.sh is a good idea.

It should also start with a shebang (like #!/bin/sh)

Considering your script (bootstrap.sh: a couple of git config --global commands), it would be best to RUN that script once in your Dockerfile, but making sure to use the right user (the global git config file is %HOME%/.gitconfig, which by default is the /root one)

Add to your Dockerfile:

RUN /bootstrap.sh

Then, when running a container, check the content of /root/.gitconfig to confirm the script was run.

I asked the same question some time ago and had to answer it myself. Here's what I came up with:

It seems, my first thought [that it comes from its JavaScript roots] was correct.

'\/' === '/' in JavaScript, and JSON is valid JavaScript. However, why are the other ignored escapes (like \z) not allowed in JSON?

The key for this was reading http://www.cs.tut.fi/~jkorpela/www/revsol.html, followed by http://www.w3.org/TR/html4/appendix/notes.html#h-B.3.2. The feature of the slash escape allows JSON to be embedded in HTML (as SGML) and XML.

select column1 || ' ' || column2 as whole_name FROM tablename;

Here || is the concat operator used for concatenating them to single column and ('') inside || used for space between two columns.

string filePath = HttpContext.Current.Server.MapPath("~/folderName/filename.extension");

OR

string filePath = HttpContext.Server.MapPath("~/folderName/filename.extension");

This typically stems from a bug in revision control system, or similar. This was a product from CVS, if a file was checked in from Windows to Unix server, and then checked out again...

In other words, it is just broken...

You also need add these lines in PostgreSQL and restart the server:

log_directory = 'pg_log'                    
log_filename = 'postgresql-dateformat.log'
log_statement = 'all'
logging_collector = on

It sounds like you need to make use of advanced where clauses.

Given that search in field1 and field2 is constant we will leave them as is, but we are going to adjust your search in datefield a little.

Try this:

$query = Model::where('field1', 1)
    ->whereNull('field2')
    ->where(function ($query) {
        $query->where('datefield', '<', $date)
            ->orWhereNull('datefield');
    }
);

If you ever need to debug a query and see why it isn't working, it can help to see what SQL it is actually executing. You can chain ->toSql() to the end of your eloquent query to generate the SQL.

I don't know if it is stylable with CSS (probably not in IE), but please: do not use a "fake" drop-down box using javascript, because the usability of these things usually is horrible. Among other things, keyboard navigation is usually absent.

One point no one has mention that make sure your Host Activity launch mode must not set to singleInstance or singleTask.

onActivityResult will not work if your launch mode set to SingleInstance or SingleTask. or you call your activity using these IntentFilters

standard or singleTop launch mode will work fine.

I eventually used:

weather["Temp"] = weather["Temp"].convert_objects(convert_numeric=True)

It worked just fine, except that I got the following message.

C:\ProgramData\Anaconda3\lib\site-packages\ipykernel_launcher.py:3: FutureWarning:
convert_objects is deprecated.  Use the data-type specific converters pd.to_datetime, pd.to_timedelta and pd.to_numeric.

As close as I can tell, Chrome is looking for the header

Content-Type: text/xml

Then it works --- other iterations have failed.

Make sure your web server is providing this. It also explains why it fails for file://URI xml files.

You can use :

-XX:MaxPermSize=128m

to increase the space. But this usually only postpones the inevitable.

You can also enable the PermGen to be garbage collected

-XX:+UseConcMarkSweepGC -XX:+CMSPermGenSweepingEnabled -XX:+CMSClassUnloadingEnabled

Usually this occurs when doing lots of redeploys. I am surprised you have it using something like indexing. Use virtualvm or jconsole to monitor the Perm gen space and check it levels off after warming up the indexing.

Maybe you should consider changing to another JVM like the IBM JVM. It does not have a Permanent Generation and is immune to this issue.

All the above solutions are good, but I like @Steve's and @bejota's the best as they do not involve fancy calls and are universal.

By universal I mean that works with any type of axes including GeoAxes. For example, it you have projected axes for mapping:

projection = cartopy.crs.UTM(zone='17N')
ax = plt.axes(projection=projection)
im = ax.imshow(np.arange(200).reshape((20, 10)))

a call to

cax = divider.append_axes("right", size=width, pad=pad)

will fail with: KeyException: map_projection

Therefore, the only universal way of dealing colorbar size with all types of axes is:

ax.colorbar(im, fraction=0.046, pad=0.04)

Work with fraction from 0.035 to 0.046 to get your best size. However, the values for the fraction and paddig will need to be adjusted to get the best fit for your plot and will differ depending if the orientation of the colorbar is in vertical position or horizontal.

You can hijack your Android audio port using an Arduino board like this. Then, you have two options (as far as I'm concerned):

1) Buy another Arduino Shield that supports RFID. I haven't seen one that supports UHF so far.

2) Try to connect your Arduino hijack with a USB RFID reader and build some embedded hardware kit.

Right now, I'm working in the second option but with iPhone.

In v2.0 of the Graph API, calling /me/friends returns the person's friends who also use the app.

In addition, in v2.0, you must request the user_friends permission from each user. user_friends is no longer included by default in every login. Each user must grant the user_friends permission in order to appear in the response to /me/friends. See the Facebook upgrade guide for more detailed information, or review the summary below.

The /me/friendlists endpoint and user_friendlists permission are not what you're after. This endpoint does not return the users friends - its lets you access the lists a person has made to organize their friends. It does not return the friends in each of these lists. This API and permission is useful to allow you to render a custom privacy selector when giving people the opportunity to publish back to Facebook.

If you want to access a list of non-app-using friends, there are two options:

1. If you want to let your people tag their friends in stories that they publish to Facebook using your App, you can use the /me/taggable_friends API. Use of this endpoint requires review by Facebook and should only be used for the case where you're rendering a list of friends in order to let the user tag them in a post.

2. If your App is a Game AND your Game supports Facebook Canvas, you can use the /me/invitable_friends endpoint in order to render a custom invite dialog, then pass the tokens returned by this API to the standard Requests Dialog.

In other cases, apps are no longer able to retrieve the full list of a user's friends (only those friends who have specifically authorized your app using the user_friends permission).

For apps wanting allow people to invite friends to use an app, you can still use the Send Dialog on Web or the new Message Dialog on iOS and Android.

Recently, I have seen this problem too. Below, you have my solution:

1. ping github.com, if ping failed. it is DNS error.
2. sudo vim /etc/resolv.conf, the add: nameserver 8.8.8.8 nameserver 8.8.4.4

Or it can be a genuine network issue. Restart your network-manager using sudo service network-manager restart or fix it up

I have just received this error after switching from HTTPS to SSH (for my origin remote). To fix, I simply ran the following command (for each repo):

ssh -T [email protected]

Upon receiving a successful response, I could fetch/push to the repo with ssh.

I took that command from Git's Testing your SSH connection guide, which is part of the greater Connecting to GitHub with with SSH guide.

Just as addition to @thatjuan's answer.
More compatible PHP4 version of this:

if (!function_exists('http_build_query')) {
    if (!defined('PHP_QUERY_RFC1738')) {
        define('PHP_QUERY_RFC1738', 1);
    }
    if (!defined('PHP_QUERY_RFC3986')) {
        define('PHP_QUERY_RFC3986', 2);
    }
    function http_build_query($query_data, $numeric_prefix = '', $arg_separator = '&', $enc_type = PHP_QUERY_RFC1738)
    {
        $data = array();
        foreach ($query_data as $key => $value) {
            if (is_numeric($key)) {
                $key = $numeric_prefix . $key;
            }
            if (is_scalar($value)) {
                $k = $enc_type == PHP_QUERY_RFC3986 ? urlencode($key) : rawurlencode($key);
                $v = $enc_type == PHP_QUERY_RFC3986 ? urlencode($value) : rawurlencode($value);
                $data[] = "$k=$v";
            } else {
                foreach ($value as $sub_k => $val) {
                    $k = "$key[$sub_k]";
                    $k = $enc_type == PHP_QUERY_RFC3986 ? urlencode($k) : rawurlencode($k);
                    $v = $enc_type == PHP_QUERY_RFC3986 ? urlencode($val) : rawurlencode($val);
                    $data[] = "$k=$v";
                }
            }
        }
        return implode($arg_separator, $data);
    }
}

Unfortunatelly, today (September 2018) you can not find cross-browser solution for client side file writing.

For example: in some browser like a Chrome we have today this possibility and we can write with FileSystemFileEntry.createWriter() with client side call, but according to the docu:

This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

---

For IE (but not MS Edge) we could use ActiveX too, but this is only for this client.

If you want update your JSON file cross-browser you have to use server and client side together.

The client side script

On client side you can make a request to the server and then you have to read the response from server. Or you could read a file with FileReader too. For the cross-browser writing to the file you have to have some server (see below on server part).

var xhr = new XMLHttpRequest(),
    jsonArr,
    method = "GET",
    jsonRequestURL = "SOME_PATH/jsonFile/";

xhr.open(method, jsonRequestURL, true);
xhr.onreadystatechange = function()
{
    if(xhr.readyState == 4 && xhr.status == 200)
    {
        // we convert your JSON into JavaScript object
        jsonArr = JSON.parse(xhr.responseText);

        // we add new value:
        jsonArr.push({"nissan": "sentra", "color": "green"});

        // we send with new request the updated JSON file to the server:
        xhr.open("POST", jsonRequestURL, true);
        xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
        // if you want to handle the POST response write (in this case you do not need it):
        // xhr.onreadystatechange = function(){ /* handle POST response */ };
        xhr.send("jsonTxt="+JSON.stringify(jsonArr));
        // but on this place you have to have a server for write updated JSON to the file
    }
};
xhr.send(null);

Server side scripts

You can use a lot of different servers, but I would like to write about PHP and Node.js servers.

By using searching machine you could find "free PHP Web Hosting*" or "free Node.js Web Hosting". For PHP server I would recommend 000webhost.com and for Node.js I would recommend to see and to read this list.

PHP server side script solution

The PHP script for reading and writing from JSON file:

<?php

// This PHP script must be in "SOME_PATH/jsonFile/index.php"

$file = 'jsonFile.txt';

if($_SERVER['REQUEST_METHOD'] === 'POST')
// or if(!empty($_POST))
{
    file_put_contents($file, $_POST["jsonTxt"]);
    //may be some error handeling if you want
}
else if($_SERVER['REQUEST_METHOD'] === 'GET')
// or else if(!empty($_GET))
{
    echo file_get_contents($file);
    //may be some error handeling if you want
}
?>

Node.js server side script solution

I think that Node.js is a little bit complex for beginner. This is not normal JavaScript like in browser. Before you start with Node.js I would recommend to read one from two books:

• Learning Node: Moving to the Server-Side
• Node.js Web Development: Server-side development

The Node.js script for reading and writing from JSON file:

var http = require("http"),
    fs = require("fs"),
    port = 8080,
    pathToJSONFile = '/SOME_PATH/jsonFile.txt';

http.createServer(function(request, response)
{
    if(request.method == 'GET')
    {
        response.writeHead(200, {"Content-Type": "application/json"});
        response.write(fs.readFile(pathToJSONFile, 'utf8'));
        response.end();
    }
    else if(request.method == 'POST')
    {
        var body = [];

        request.on('data', function(chunk)
        {
            body.push(chunk);
        });

        request.on('end', function()
        {
            body = Buffer.concat(body).toString();
            var myJSONdata = body.split("=")[1];
            fs.writeFileSync(pathToJSONFile, myJSONdata); //default: 'utf8'
        });
    }
}).listen(port);

System.IO.File.Create(@"C:\Temp.txt");

As others have pointed out, you should dispose of this object or wrap it in an empty using statement.

using (System.IO.File.Create(@"C:\Temp.txt"));

You could try merge

var finalObj = $.merge(json1, json2);

If there's only some few components of your webview that is slow or laggy, try adding this to the elements css:

transform: translate3d(0,0,0);
-webkit-transform: translate3d(0,0,0);

This has been the only speedhack that really had a effect on my webview. But be careful not to overuse it! (you can read more about the hack in this article.)

Dirk's method above will absolutely work, but if you're looking for a way to bring in a long string where whitespace/structure is important to preserve (example: a SQL query using RODBC) there is a two step solution.

1) Bring the text string in across multiple lines

long_string <- "this
is 
a 
long
string
with
whitespace"

2) R will introduce a bunch of \n characters. Strip those out with strwrap(), which destroys whitespace, per the documentation:

strwrap(long_string, width=10000, simplify=TRUE)

By telling strwrap to wrap your text to a very, very long row, you get a single character vector with no whitespace/newline characters.

Contents of table cell, variable height, could be more than 60px;

<div style="position: absolute; bottom: 0px;">
    Notice
</div>

I would recommend using Oracle's "dbms_crypto.randombytes" function.

Why?
This function returns a RAW value containing a cryptographically secure pseudo-random sequence of bytes, which can be used to generate random material for encryption keys.

select REGEXP_REPLACE(dbms_crypto.randombytes(16), '(.{8})(.{4})(.{4})(.{4})(.{12})', '\1-\2-\3-\4-\5') from dual;

You should not use the function "sys_guid" because only one character changes.

ALTER TABLE locations ADD (uid_col RAW(16));

UPDATE locations SET uid_col = SYS_GUID();

SELECT location_id, uid_col FROM locations
   ORDER BY location_id, uid_col;

LOCATION_ID UID_COL

You can use

str1.compareTo(str2);

If str1 is lexicographically less than str2, a negative number will be returned, 0 if equal or a positive number if str1 is greater.

E.g.,

"a".compareTo("b"); // returns a negative number, here -1
"a".compareTo("a"); // returns  0
"b".compareTo("a"); // returns a positive number, here 1
"b".compareTo(null); // throws java.lang.NullPointerException

When there is no records returned from Database for a particular condition and When I tried to access the rs.getString(1); I got this error "exhausted resultset".

Before the issue, my code was:

rs.next();
sNr= rs.getString(1);

After the fix:

while (rs.next()) {
    sNr = rs.getString(1);
}

I'm currently using Bootstrap 4.3 in Angular 8 and want to open modal window programmatically (without actually clicking on some button as the official demo shows).

Following method works for me: The general idea is to create a button associated to a modal window. First make sure after you click this button, it can open the modal. Then give this button tag an id using hashtag, for example #hiddenBtn. In component ts file, import ViewChild from @angular/core and write below code:

@ViewChild('hiddenBtn', {static: false}) myHiddenBtn;

After that, whenever you want to open this modal window in your component ts code, write following code to simulate click operation

this.myHiddenBtn.nativeElement.click();

If you're using .NET 4.5 and want to use async then you can use HttpClient in System.Net.Http:

using (var httpClient = new HttpClient())
{
    var json = await httpClient.GetStringAsync("url");

    // Now parse with JSON.Net
}

There is a convenient Unipath module.

>>> from unipath import Path 
>>>  
>>> Path('/var/log').exists()
True
>>> Path('/var/log').isdir()
True

Other related things you might need:

>>> Path('/var/log/system.log').parent
Path('/var/log')
>>> Path('/var/log/system.log').ancestor(2)
Path('/var')
>>> Path('/var/log/system.log').listdir()
[Path('/var/foo'), Path('/var/bar')]
>>> (Path('/var/log') + '/system.log').isfile()
True

You can install it using pip:

$ pip3 install unipath

It's similar to the built-in pathlib. The difference is that it treats every path as a string (Path is a subclass of the str), so if some function expects a string, you can easily pass it a Path object without a need to convert it to a string.

For example, this works great with Django and settings.py:

# settings.py
BASE_DIR = Path(__file__).ancestor(2)
STATIC_ROOT = BASE_DIR + '/tmp/static'

I just rechecked the performance on http://jsperf.com/javascript-concat-vs-join/2. The test-cases concatenate or join the alphabet 1,000 times.

In current browsers (FF, Opera, IE11, Chrome), "concat" is about 4-10 times faster than "join".

In IE8, both return about equal results.

In IE7, "join" is about 100 times faster unfortunately.

If you are using an emulator for testing then you must use <uses-permission android:name="android.permission.INTERNET" />only and ignore <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />.It's work for me.

Assuming you are decoding or encoding xml and using JAXB, then it's possible to replace the dateTime binding entirely and use something else than `XMLGregorianCalendar' for every date in the schema.

In that way you can have JAXB do the repetitive stuff while you can spend the time on writing awesome code that delivers value.

Example for a jodatime DateTime: (Doing this with java.util.Date would also work - but with certain limitations. I prefer jodatime and it's copied from my code so I know it works...)

<jxb:globalBindings>
    <jxb:javaType name="org.joda.time.LocalDateTime" xmlType="xs:dateTime"
        parseMethod="test.util.JaxbConverter.parseDateTime"
        printMethod="se.seb.bis.test.util.JaxbConverter.printDateTime" />
    <jxb:javaType name="org.joda.time.LocalDate" xmlType="xs:date"
        parseMethod="test.util.JaxbConverter.parseDate"
        printMethod="test.util.JaxbConverter.printDate" />
    <jxb:javaType name="org.joda.time.LocalTime" xmlType="xs:time"
        parseMethod="test.util.JaxbConverter.parseTime"
        printMethod="test.util.JaxbConverter.printTime" />
    <jxb:serializable uid="2" />
</jxb:globalBindings>

And the converter:

public class JaxbConverter {
static final DateTimeFormatter dtf = ISODateTimeFormat.dateTimeNoMillis();
static final DateTimeFormatter df = ISODateTimeFormat.date();
static final DateTimeFormatter tf = ISODateTimeFormat.time();

public static LocalDateTime parseDateTime(String s) {
    try {
        if (StringUtils.trimToEmpty(s).isEmpty())
            return null;
        LocalDateTime r = dtf.parseLocalDateTime(s);
        return r;
    } catch (Exception e) {
        throw new IllegalArgumentException(e);
    }
}

public static String printDateTime(LocalDateTime d) {
    try {
        if (d == null)
            return null;
        return dtf.print(d);
    } catch (Exception e) {
        throw new IllegalArgumentException(e);
    }
}

public static LocalDate parseDate(String s) {
    try {
        if (StringUtils.trimToEmpty(s).isEmpty())
            return null;
        return df.parseLocalDate(s);
    } catch (Exception e) {
        throw new IllegalArgumentException(e);
    }
}

public static String printDate(LocalDate d) {
    try {
        if (d == null)
            return null;
        return df.print(d);
    } catch (Exception e) {
        throw new IllegalArgumentException(e);
    }
}

public static String printTime(LocalTime d) {
    try {
        if (d == null)
            return null;
        return tf.print(d);
    } catch (Exception e) {
        throw new IllegalArgumentException(e);
    }
}

public static LocalTime parseTime(String s) {
    try {
        if (StringUtils.trimToEmpty(s).isEmpty())
            return null;
        return df.parseLocalTime(s);
    } catch (Exception e) {
        throw new IllegalArgumentException(e);
    }
}

See here: how replace XmlGregorianCalendar by Date?

If you are happy to just map to an instant based on the timezone+timestamp, and the original timezone is not really relevant, then java.util.Date is probably fine too.

Perhaps the easiest way to see which extensions are (compiled and) loaded (not in cli) is to have a server run the following:

<?php
$ext = get_loaded_extensions();
asort($ext);
foreach ($ext as $ref) {
    echo $ref . "\n";
}

PHP cli does not necessarily have the same extensions loaded.

If that is a copy/paste from your script, you've permuted this line:

#!/usr/env/bin bash

There's no #!/usr/env/bin, you meant #!/usr/bin/env.

Its .net Version mismatch of the dll so try changing to from in app.config or web.config. Generally have a higher Framework than lower because when we add system's dll to the lower version built .net application so it won't work therefore just change to the higher version

Following is the best way to get of the issue , check following on classpath:

1. Make sure JAVA_HOME system variable must have till jdk e.g C:\Program Files\Java\jdk1.7.0_80 , don't append bin here.

2. Because MAVEN will look for jre which is under C:\Program Files\Java\jdk1.7.0_80

3. Set %JAVA_HOME%\bin in classpath .

Then try Maven version .

Hope it will help .

You can create one file that contains the set schema ... statement and then include the actual file you want to run:

Create a file run_insert.sql:

set schema 'my_schema_01';
\i myInsertFile.sql

Then call this using:

psql -d myDataBase -a -f run_insert.sql

All of this didn't solve it for me on my brand new Ubuntu 15.04.

I removed the LOCAL and got this command:

LOAD DATA
INFILE A.txt
INTO DB
LINES TERMINATED BY '|';

but then I got:

MySQL said: File 'A.txt' not found (Errcode: 13 - Permission denied)

That led me to this answer from Nelson to another question on stackoverflow which solved the issue for me!

How about this solution

$order = array(1,5,2,4,3,6);

$array = array(
    1 => 'one',
    2 => 'two',
    3 => 'three',
    4 => 'four',
    5 => 'five',
    6 => 'six'
);

uksort($array, function($key1, $key2) use ($order) {
    return (array_search($key1, $order) > array_search($key2, $order));
});

The updated dplyr solution, as for 2020

1: summarise_each_() is deprecated as of dplyr 0.7.0. and 2: funs() is deprecated as of dplyr 0.8.0.

ag.dplyr <- DF %>% group_by(ID) %>% summarise(across(.cols = everything(),list(mean = mean, sd = sd)))

No, unfortunately this will not be possible because ConverterParameter is not a DependencyProperty so you won't be able to use bindings

But perhaps you could cheat and use a MultiBinding with IMultiValueConverter to pass in the 2 Tag properties.

Date() is not part of jQuery, it is one of JavaScript's features.

See the documentation on Date object.

You can do it like that:

var d = new Date();

var month = d.getMonth()+1;
var day = d.getDate();

var output = d.getFullYear() + '/' +
    (month<10 ? '0' : '') + month + '/' +
    (day<10 ? '0' : '') + day;

See this jsfiddle for a proof.

The code may look like a complex one, because it must deal with months & days being represented by numbers less than 10 (meaning the strings will have one char instead of two). See this jsfiddle for comparison.

Use the (excellent) JSON-Java library from json.org then

JSONObject json = new JSONObject(str);
String xml = XML.toString(json);

toString can take a second argument to provide the name of the XML root node.

This library is also able to convert XML to JSON using XML.toJSONObject(java.lang.String string)

Check the Javadoc

Type       | Approx. Length     | Exact Max. Length Allowed
-----------------------------------------------------------
TINYTEXT   | 256 Bytes          |           255 characters
TEXT       |  64 Kilobytes      |        65,535 characters
MEDIUMTEXT |  16 Megabytes      |    16,777,215 characters
LONGTEXT   |   4 Gigabytes      | 4,294,967,295 characters

Basically, it's like:

"Exact Max. Length Allowed" = "Approx. Length" in bytes - 1

Note: If using multibyte characters (like Arabic, where each Arabic character takes 2 bytes), the column "Exact Max. Length Allowed" for TINYTEXT can hold be up to 127 Arabic characters (Note: space, dash, underscore, and other such characters, are 1-byte characters).

Not possible to load static local files(eg:svg) without server. If you have NPM /YARN installed in your machine, you can setup simple http server using "http-server"

npm install http-server -g
http-server [path] [options]

Or open terminal in that project folder and type "hs". It will automaticaly start HTTP live server.

Create a css class that applies the row color, and use jQuery to toggle the class on/off:

CSS:

.selected {
    background-color: blue;
}

jQuery:

$('#data tr').on('click', function() {
    $(this).toggleClass('selected');
});

The first click will add the class (making the background color blue), and the next click will remove the class, reverting it to whatever it was before. Repeat!

In terms of the two CSS classes you already have, I would change the .nonhighlighted class to apply to all rows of the table by default, then toggle the .highlighted on and off:

<style type="text/css">

.highlighted {
    background: red;
}

#data tr {
    background: white;
}

</style>

$('#data tr').on('click', function() {
    $(this).toggleClass('highlighted');
});

If you have perl installed, then perl -i -n -e"print unless m{(ERROR|REFERENCE)}" should do the trick.

The operations needed to be performed, require numpy arrays either created via

np.array()

or can be converted from list to an array via

np.stack()

As in the above mentioned case, 2 lists are inputted as operands it triggers the error.

@T0xicCode's answer is correct, but I thought I would expand on the details since it actually took me about 20 hours to finally get a working solution implemented.

If you're looking to run Nginx in its own container and use it as a reverse proxy to load balance multiple applications on the same server instance then the steps you need to follow are as such:

Link Your Containers

When you docker run your containers, typically by inputting a shell script into User Data, you can declare links to any other running containers. This means that you need to start your containers up in order and only the latter containers can link to the former ones. Like so:

#!/bin/bash
sudo docker run -p 3000:3000 --name API mydockerhub/api
sudo docker run -p 3001:3001 --link API:API --name App mydockerhub/app
sudo docker run -p 80:80 -p 443:443 --link API:API --link App:App --name Nginx mydockerhub/nginx

So in this example, the API container isn't linked to any others, but the App container is linked to API and Nginx is linked to both API and App.

The result of this is changes to the env vars and the /etc/hosts files that reside within the API and App containers. The results look like so:

/etc/hosts

Running cat /etc/hosts within your Nginx container will produce the following:

172.17.0.5  0fd9a40ab5ec
127.0.0.1   localhost
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
172.17.0.3  App
172.17.0.2  API

ENV Vars

Running env within your Nginx container will produce the following:

API_PORT=tcp://172.17.0.2:3000
API_PORT_3000_TCP_PROTO=tcp
API_PORT_3000_TCP_PORT=3000
API_PORT_3000_TCP_ADDR=172.17.0.2

APP_PORT=tcp://172.17.0.3:3001
APP_PORT_3001_TCP_PROTO=tcp
APP_PORT_3001_TCP_PORT=3001
APP_PORT_3001_TCP_ADDR=172.17.0.3

I've truncated many of the actual vars, but the above are the key values you need to proxy traffic to your containers.

To obtain a shell to run the above commands within a running container, use the following:

sudo docker exec -i -t Nginx bash

You can see that you now have both /etc/hosts file entries and env vars that contain the local IP address for any of the containers that were linked. So far as I can tell, this is all that happens when you run containers with link options declared. But you can now use this information to configure nginx within your Nginx container.

Configuring Nginx

This is where it gets a little tricky, and there's a couple of options. You can choose to configure your sites to point to an entry in the /etc/hosts file that docker created, or you can utilize the ENV vars and run a string replacement (I used sed) on your nginx.conf and any other conf files that may be in your /etc/nginx/sites-enabled folder to insert the IP values.

OPTION A: Configure Nginx Using ENV Vars

This is the option that I went with because I couldn't get the /etc/hosts file option to work. I'll be trying Option B soon enough and update this post with any findings.

The key difference between this option and using the /etc/hosts file option is how you write your Dockerfile to use a shell script as the CMD argument, which in turn handles the string replacement to copy the IP values from ENV to your conf file(s).

Here's the set of configuration files I ended up with:

Nginx-Startup.sh

sed -i 's/APP_IP/'"$APP_PORT_3001_TCP_ADDR"'/g' /etc/nginx/sites-enabled/app.myapp.com

service nginx start

I'll leave it up to you to do your homework about most of the contents of nginx.conf and api.myapp.conf.

The magic happens in Nginx-Startup.sh where we use sed to do string replacement on the APP_IP placeholder that we've written into the upstream block of our api.myapp.conf and app.myapp.conf files.

This ask.ubuntu.com question explains it very nicely: Find and replace text within a file using commands

GOTCHA On OSX, sed handles options differently, the -i flag specifically. On Ubuntu, the -i flag will handle the replacement 'in place'; it will open the file, change the text, and then 'save over' the same file. On OSX, the -i flag requires the file extension you'd like the resulting file to have. If you're working with a file that has no extension you must input '' as the value for the -i flag.

GOTCHA To use ENV vars within the regex that sed uses to find the string you want to replace you need to wrap the var within double-quotes. So the correct, albeit wonky-looking, syntax is as above.

So docker has launched our container and triggered the Nginx-Startup.sh script to run, which has used sed to change the value APP_IP to the corresponding ENV variable we provided in the sed command. We now have conf files within our /etc/nginx/sites-enabled directory that have the IP addresses from the ENV vars that docker set when starting up the container. Within your api.myapp.conf file you'll see the upstream block has changed to this:

upstream api_upstream{
    server 172.0.0.2:3000;
}

The IP address you see may be different, but I've noticed that it's usually 172.0.0.x.

You should now have everything routing appropriately.

GOTCHA You cannot restart/rerun any containers once you've run the initial instance launch. Docker provides each container with a new IP upon launch and does not seem to re-use any that its used before. So api.myapp.com will get 172.0.0.2 the first time, but then get 172.0.0.4 the next time. But Nginx will have already set the first IP into its conf files, or in its /etc/hosts file, so it won't be able to determine the new IP for api.myapp.com. The solution to this is likely to use CoreOS and its etcd service which, in my limited understanding, acts like a shared ENV for all machines registered into the same CoreOS cluster. This is the next toy I'm going to play with setting up.

OPTION B: Use /etc/hosts File Entries

This should be the quicker, easier way of doing this, but I couldn't get it to work. Ostensibly you just input the value of the /etc/hosts entry into your api.myapp.conf and app.myapp.conf files, but I couldn't get this method to work.

UPDATE: See @Wes Tod's answer for instructions on how to make this method work.

Here's the attempt that I made in api.myapp.conf:

upstream api_upstream{
    server API:3000;
}

Considering that there's an entry in my /etc/hosts file like so: 172.0.0.2 API I figured it would just pull in the value, but it doesn't seem to be.

I also had a couple of ancillary issues with my Elastic Load Balancer sourcing from all AZ's so that may have been the issue when I tried this route. Instead I had to learn how to handle replacing strings in Linux, so that was fun. I'll give this a try in a while and see how it goes.

Using a CTE generated numbers table to examine each character, then FOR XML to concat to a string of kept values you can...

CREATE FUNCTION [dbo].[PatRemove](
    @pattern varchar(50),
    @expression varchar(8000) 
    )
RETURNS varchar(8000)
AS
BEGIN
    WITH 
        d(d) AS (SELECT d FROM (VALUES (0),(1),(2),(3),(4),(5),(6),(7),(8),(9)) digits(d)),
        nums(n) AS (SELECT ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) FROM d d1, d d2, d d3, d d4),
        chars(c) AS (SELECT SUBSTRING(@expression, n, 1) FROM nums WHERE n <= LEN(@expression))
    SELECT 
        @expression = (SELECT c AS [text()] FROM chars WHERE c NOT LIKE @pattern FOR XML PATH(''));

    RETURN @expression;
END

The question is to have a ‘waiting’ indicator while a file is generated and then return to normal once the file is downloading. The way I like todo this is using a hidden iFrame and hook the frame’s onload event to let my page know when download starts. BUT onload does not fire in IE for file downloads (like with the attachment header token). Polling the server works, but I dislike the extra complexity. So here is what I do:

• Target the hidden iFrame as usual.
• Generate the content. Cache it with an absolute timeout in 2 minutes.
• Send a javascript redirect back to the calling client, essentially calling the generator page a second time. NOTE: this will cause the onload event to fire in IE because it's acting like a regular page.
• Remove the content from the cache and send it to the client.

Disclaimer, don’t do this on a busy site, because of the caching could add up. But really, if your sites that busy the long running process will starve you of threads anyways.

Here is what the codebehind looks like, which is all you really need.

public partial class Download : System.Web.UI.Page
{
    protected System.Web.UI.HtmlControls.HtmlControl Body;

    protected void Page_Load( object sender, EventArgs e )
    {
        byte[ ] data;
        string reportKey = Session.SessionID + "_Report";

        // Check is this page request to generate the content
        //    or return the content (data query string defined)
        if ( Request.QueryString[ "data" ] != null )
        {
            // Get the data and remove the cache
            data = Cache[ reportKey ] as byte[ ];
            Cache.Remove( reportKey );

            if ( data == null )                    
                // send the user some information
                Response.Write( "Javascript to tell user there was a problem." );                    
            else
            {
                Response.CacheControl = "no-cache";
                Response.AppendHeader( "Pragma", "no-cache" );
                Response.Buffer = true;

                Response.AppendHeader( "content-disposition", "attachment; filename=Report.pdf" );
                Response.AppendHeader( "content-size", data.Length.ToString( ) );
                Response.BinaryWrite( data );
            }
            Response.End();                
        }
        else
        {
            // Generate the data here. I am loading a file just for an example
            using ( System.IO.FileStream stream = new System.IO.FileStream( @"C:\1.pdf", System.IO.FileMode.Open ) )
                using ( System.IO.BinaryReader reader = new System.IO.BinaryReader( stream ) )
                {
                    data = new byte[ reader.BaseStream.Length ];
                    reader.Read( data, 0, data.Length );
                }

            // Store the content for retrieval              
            Cache.Insert( reportKey, data, null, DateTime.Now.AddMinutes( 5 ), TimeSpan.Zero );

            // This is the key bit that tells the frame to reload this page 
            //   and start downloading the content. NOTE: Url has a query string 
            //   value, so that the content isn't generated again.
            Body.Attributes.Add("onload", "window.location = 'binary.aspx?data=t'");
        }
    }

As far as I know, there are three different ways.

Use \n in your print:

print("first line\nSecond line")

Use sep="\n" in print:

print("first line", "second line", sep="\n")

Use triple quotes and a multiline string:

print("""
Line1
Line2
""")

Here's how extend/assign works: For each property in source, copy its value as-is to destination. if property values themselves are objects, there is no recursive traversal of their properties. Entire object would be taken from source and set in to destination.

Here's how merge works: For each property in source, check if that property is object itself. If it is then go down recursively and try to map child object properties from source to destination. So essentially we merge object hierarchy from source to destination. While for extend/assign, it's simple one level copy of properties from source to destination.

If you are using iframe in your webpage you might encounter a problem while changing the whole page through a HTML hyperlink (anchor tag) from the iframe. There are two solutions to mitigate this problem.

Solution 1. You can use target attribute of anchor tag as given in the following example.

<a target="_parent" href="http://www.kriblog.com">link</a>

Solution 2. You can also open a new page in parent window from iframe with JavaScript.

<a href="#" onclick="window.parent.location.href='http://www.kriblog.com';">

Remember ? target="_parent" has been deprecated in XHTML, but it is still supported in HTML 5.x.

More can be read from following link http://www.kriblog.com/html/link-of-iframe-open-in-the-parent-window.html

I have a partial solution that I came up with. It uses a regular expression to extract the month and day name. But as I look through the Region and Language options (Windows) I realize that different cultures have different format order... maybe a better regular expression pattern could be useful.

function testDateInfo() {
        var months = new Array();
        var days = new Array();
        var workingDate = new Date();
        workingDate.setHours(0, 0, 0, 0);
        workingDate.setDate(1);
        var RE = new RegExp("([a-z]+)","ig");
        //-- get day names 0-6
        for (var i = 0; i < 7; i++) {

            var day = workingDate.getDay();
            //-- will eventually be in order
            if (days[day] == undefined)
                days[day] = workingDate.toLocaleDateString().match(RE)[0];
            workingDate.setDate(workingDate.getDate() + 1);
        }
        //--get month names 0-11
        for (var i = 0; i < 12; i++) {
            workingDate.setMonth(i);
            months.push(workingDate.toLocaleDateString().match(RE)[1]);
        }
        alert(days.join(",") + " \n\r " + months.join(","));
    }

As a commenter mentioned you can get Values from net/url which has an Encode method. You could do something like this (req.URL.Query() returns the existing url.Values)

package main

import (
    "fmt"
    "log"
    "net/http"
    "os"
)

func main() {
    req, err := http.NewRequest("GET", "http://api.themoviedb.org/3/tv/popular", nil)
    if err != nil {
        log.Print(err)
        os.Exit(1)
    }

    q := req.URL.Query()
    q.Add("api_key", "key_from_environment_or_flag")
    q.Add("another_thing", "foo & bar")
    req.URL.RawQuery = q.Encode()

    fmt.Println(req.URL.String())
    // Output:
    // http://api.themoviedb.org/3/tv/popular?another_thing=foo+%26+bar&api_key=key_from_environment_or_flag
}

Line 11:

.postItem img {
    height: auto;
    width: 450px;
}

You can either edit your CSS, or you can listen to Mageek and use INLINE STYLING to override the CSS styling that's happening:

<img src="theSource" style="width:30px;" />

Avoid setting both width and height, as the image itself might not be scaled proportionally. But you can set the dimensions to whatever you want, as per Mageek's example.

You can access most IP cameras using the method below.

import cv2 

# insert the HTTP(S)/RSTP feed from the camera
url = "http://username:password@your_ip:your_port/tmpfs/auto.jpg"

# open the feed
cap = cv2.VideoCapture(url)

while True:
    # read next frame
     ret, frame = cap.read()
    
    # show frame to user
     cv2.imshow('frame', frame)
    
    # if user presses q quit program
     if cv2.waitKey(1) & 0xFF == ord("q"):
        break

# close the connection and close all windows
cap.release()
cv2.destroyAllWindows()

Try to add this:

curl_setopt($ch, CURLOPT_HEADER, 1); 
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1); 

I tried all the solutions on here and none gave a clean 1px line. To achieve this do the following:

border: none; border-top: 1px dotted #000;

Alternatively:

 border-top: 1px dotted #000; border-right: none; border-bottom: none; border-left: none;

It is a generic type parameter, see Generics documentation.

T is not a reserved keyword. T, or any given name, means a type parameter. Check the following method (just as a simple example).

T GetDefault<T>()
{
    return default(T);
}

Note that the return type is T. With this method you can get the default value of any type by calling the method as:

GetDefault<int>(); // 0
GetDefault<string>(); // null
GetDefault<DateTime>(); // 01/01/0001 00:00:00
GetDefault<TimeSpan>(); // 00:00:00

.NET uses generics in collections, ... example:

List<int> integerList = new List<int>();

This way you will have a list that only accepts integers, because the class is instancited with the type T, in this case int, and the method that add elements is written as:

public class List<T> : ...
{
    public void Add(T item);
}

Some more information about generics.

You can limit the scope of the type T.

The following example only allows you to invoke the method with types that are classes:

void Foo<T>(T item) where T: class
{
}

The following example only allows you to invoke the method with types that are Circle or inherit from it.

void Foo<T>(T item) where T: Circle
{
}

And there is new() that says you can create an instance of T if it has a parameterless constructor. In the following example T will be treated as Circle, you get intellisense...

void Foo<T>(T item) where T: Circle, new()
{
    T newCircle = new T();
}

As T is a type parameter, you can get the object Type from it. With the Type you can use reflection...

void Foo<T>(T item) where T: class
{
    Type type = typeof(T);
}

As a more complex example, check the signature of ToDictionary or any other Linq method.

public static Dictionary<TKey, TSource> ToDictionary<TSource, TKey>(this IEnumerable<TSource> source, Func<TSource, TKey> keySelector);

There isn't a T, however there is TKey and TSource. It is recommended that you always name type parameters with the prefix T as shown above.

You could name TSomethingFoo if you want to.

Facing the same HIPAA issue and found a relatively easy solution,

1. Create a hidden password field with the field name as an array.

   <input type="password" name="password[]" style="display:none" />
   

2. Use the same array for the actual password field.

   <input type="password" name="password[]" />
   

The browser (Chrome) may prompt you to "Save password" but regardless if the user selects save, the next time they login the password will auto-populate the hidden password field, the zero slot in the array, leaving the 1st slot blank.

I tried defining the array, such as "password[part2]" but it still remembered. I think it throws it off if it's an unindexed array because it has no choice but to drop it in the first spot.

Then you use your programming language of choice to access the array, PHP for example,

echo $_POST['password'][1];

To count the Hbase table record count on a proper YARN cluster you have to set the map reduce job queue name as well:

hbase org.apache.hadoop.hbase.mapreduce.RowCounter -Dmapreduce.job.queuename= < Your Q Name which you have SUBMIT access>
 < TABLE_NAME>

To add a bit more value to all the other answer's to this question, one should invest a few minutes in the question: What is the output of the following code?

#include <iostream>
void throw_exception() throw(const char *)
{
    throw 10;
}
void my_unexpected(){
    std::cout << "well - this was unexpected" << std::endl;
}
int main(int argc, char **argv){
    std::set_unexpected(my_unexpected);
    try{
        throw_exception();
    }catch(int x){
        std::cout << "catch int: " << x << std::endl;
    }catch(...){
        std::cout << "catch ..." << std::endl;
    }
}

Answer: As noted here, the program calls std::terminate() and thus none of the exception handlers will get called.

Details: First my_unexpected() function is called, but since it doesn't re-throw a matching exception type for the throw_exception() function prototype, in the end, std::terminate() is called. So the full output looks like this:

user@user:~/tmp$ g++ -o except.test except.test.cpp
user@user:~/tmp$ ./except.test
well - this was unexpected
terminate called after throwing an instance of 'int'
