Programs & Examples On #Beta

In my case the localization not worked cause of '-' symbol in the name. Example: "aero-Info.plist" And localized files: "aero-InfoPlist.strings" and "aeroInfoPlist.strings" did not work.

In the gradle.properties file, change org.gradle.jvmargs to -Xmx1024m:

org.gradle.jvmargs=**-Xmx1024m** -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

SWIFT 3: Don't know if this is what you're looking for. But I compare a string to a current timestamp to see if my string is older that now.

func checkTimeStamp(date: String!) -> Bool {
        let dateFormatter: DateFormatter = DateFormatter()
        dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
        dateFormatter.locale = Locale(identifier:"en_US_POSIX")
        let datecomponents = dateFormatter.date(from: date)

        let now = Date()

        if (datecomponents! >= now) {
            return true
        } else {
            return false
        }
    }

To use it:

if (checkTimeStamp(date:"2016-11-21 12:00:00") == false) {
    // Do something
}

It's Working

Call this method where you use

SntpClient client = new SntpClient();
if (client.requestTime("ntp.ubuntu.com", 30000)) {
  long now = client.getNtpTime();
  Date current = new Date(now);

  date2 = sdf.parse(new Date(current.getTime()).toString());
 // System.out.println(current.toString());
  Log.e(TAG, "testing SntpClient time current.toString() "+current.toString()+" , date2 = "+date2);
}

You can create a wrapper function that takes in a promise and returns an array with data if no error and the error if there was an error.

function safePromise(promise) {
  return promise.then(data => [ data ]).catch(error => [ null, error ]);
}

Use it like this in ES7 and in an async function:

async function checkItem() {
  const [ item, error ] = await safePromise(getItem(id));
  if (error) { return null; } // handle error and return
  return item; // no error so safe to use item
}

this can be done this way

appendChild is a pure javascript method where as append is a jQuery method.

Instead of handcranking your models try using something like the Json2csharp.com website. Paste In an example JSON response, the fuller the better and then pull in the resultant generated classes. This, at least, takes away some moving parts, will get you the shape of the JSON in csharp giving the serialiser an easier time and you shouldnt have to add attributes.

Just get it working and then make amendments to your class names, to conform to your naming conventions, and add in attributes later.

EDIT: Ok after a little messing around I have successfully deserialised the result into a List of Job (I used Json2csharp.com to create the class for me)

public class Job
{
        public string id { get; set; }
        public string position_title { get; set; }
        public string organization_name { get; set; }
        public string rate_interval_code { get; set; }
        public int minimum { get; set; }
        public int maximum { get; set; }
        public string start_date { get; set; }
        public string end_date { get; set; }
        public List<string> locations { get; set; }
        public string url { get; set; }
}

And an edit to your code:

        List<Job> model = null;
        var client = new HttpClient();
        var task = client.GetAsync("http://api.usa.gov/jobs/search.json?query=nursing+jobs")
          .ContinueWith((taskwithresponse) =>
          {
              var response = taskwithresponse.Result;
              var jsonString = response.Content.ReadAsStringAsync();
              jsonString.Wait();
              model = JsonConvert.DeserializeObject<List<Job>>(jsonString.Result);

          });
        task.Wait();

This means you can get rid of your containing object. Its worth noting that this isn't a Task related issue but rather a deserialisation issue.

EDIT 2:

There is a way to take a JSON object and generate classes in Visual Studio. Simply copy the JSON of choice and then Edit> Paste Special > Paste JSON as Classes. A whole page is devoted to this here:

http://blog.codeinside.eu/2014/09/08/Visual-Studio-2013-Paste-Special-JSON-And-Xml/

You may try this:

public static void main(String[] args) {
    BigDecimal a = new BigDecimal("10.12345");
    System.out.println(toPrecision(a, 2));
}

private static BigDecimal toPrecision(BigDecimal dec, int precision) {
    String plain = dec.movePointRight(precision).toPlainString();
    return new BigDecimal(plain.substring(0, plain.indexOf("."))).movePointLeft(precision);
}

OUTPUT:

10.12

in other way, you can do it with javascript , in Jquery you can use something like:

$('div:visible').last()

*reedited

The problem is in your playerMovement method. You are creating the string name of your room variables (ID1, ID2, ID3):

letsago = "ID" + str(self.dirDesc.values())

However, what you create is just a str. It is not the variable. Plus, I do not think it is doing what you think its doing:

>>>str({'a':1}.values())
'dict_values([1])'

If you REALLY needed to find the variable this way, you could use the eval function:

>>>foo = 'Hello World!'
>>>eval('foo')
'Hello World!'

or the globals function:

class Foo(object):
    def __init__(self):
        super(Foo, self).__init__()
    def test(self, name):
        print(globals()[name])

foo = Foo()
bar = 'Hello World!'
foo.text('bar')

However, instead I would strongly recommend you rethink you class(es). Your userInterface class is essentially a Room. It shouldn't handle player movement. This should be within another class, maybe GameManager or something like that.

There is also tty0tty http://sourceforge.net/projects/tty0tty/ which is a real null modem emulator for linux.

It is a simple kernel module - a small source file. I don't know why it only got thumbs down on sourceforge, but it works well for me. The best thing about it is that is also emulates the hardware pins (RTC/CTS DSR/DTR). It even implements TIOCMGET/TIOCMSET and TIOCMIWAIT iotcl commands!

On a recent kernel you may get compilation errors. This is easy to fix. Just insert a few lines at the top of the module/tty0tty.c source (after the includes):

#ifndef init_MUTEX
#define init_MUTEX(x) sema_init((x),1)
#endif

When the module is loaded, it creates 4 pairs of serial ports. The devices are /dev/tnt0 to /dev/tnt7 where tnt0 is connected to tnt1, tnt2 is connected to tnt3, etc. You may need to fix the file permissions to be able to use the devices.

edit:

I guess I was a little quick with my enthusiasm. While the driver looks promising, it seems unstable. I don't know for sure but I think it crashed a machine in the office I was working on from home. I can't check until I'm back in the office on monday.

The second thing is that TIOCMIWAIT does not work. The code seems to be copied from some "tiny tty" example code. The handling of TIOCMIWAIT seems in place, but it never wakes up because the corresponding call to wake_up_interruptible() is missing.

edit:

The crash in the office really was the driver's fault. There was an initialization missing, and the completely untested TIOCMIWAIT code caused a crash of the machine.

I spent yesterday and today rewriting the driver. There were a lot of issues, but now it works well for me. There's still code missing for hardware flow control managed by the driver, but I don't need it because I'll be managing the pins myself using TIOCMGET/TIOCMSET/TIOCMIWAIT from user mode code.

If anyone is interested in my version of the code, send me a message and I'll send it to you.

use jQuery's $.getJSON

$.getJSON('mydata.json', function(data) {
    //do stuff with your data here
});

So to make your expression work, changing && for -a will do the trick.

It is correct like this:

 if [ -f $VAR1 ] && [ -f $VAR2 ] && [ -f $VAR3 ]
 then  ....

or like

 if [[ -f $VAR1 && -f $VAR2 && -f $VAR3 ]]
 then  ....

or even

X-XSS-Protection is a HTTP header understood by Internet Explorer 8 (and newer versions). This header lets domains toggle on and off the "XSS Filter" of IE8, which prevents some categories of XSS attacks. IE8 has the filter activated by default, but servers can switch if off by setting

   X-XSS-Protection: 0

Why use a constructor and prototyping for a single object?

The above is equivalent to:

var earth= {
    someMethod: function () {
        if (console && console.log)
            console.log('some method');                             
    }
};
privateFunction1();
privateFunction2();

return {
    Person: Constructors.Person,
    PlanetEarth: earth
};

There is a way simpler way. You put the href in a paragraph just created for that href. For example:

HREF name

To address why CMD is designed to run only one service per container, let's just realize what would happen if the secondary servers run in the same container are not trivial / auxiliary but "major" (e.g. storage bundled with the frontend app). For starters, it would break down several important containerization features such as horizontal (auto-)scaling and rescheduling between nodes, both of which assume there is only one application (source of CPU load) per container. Then there is the issue of vulnerabilities - more servers exposed in a container means more frequent patching of CVEs...

So let's admit that it is a 'nudge' from Docker (and Kubernetes/Openshift) designers towards good practices and we should not reinvent workarounds (SSH is not necessary - we have docker exec / kubectl exec / oc rsh designed to replace it).

I get this error when my project .net framework version does not match the framework version of the DLL I am linking to. In my case, I was getting:

"The type or namespace name 'UserVoice' could not be found (are you missing a using directive or an assembly reference?).

UserVoice was .Net 4.0, and my project properties were set to ".Net 4.0 Client Profile". Changing to .Net 4.0 on the project cleared the error. I hope this helps someone.

I would also mention that using IOC aka Unity may make these assessments misleading. I may have erred but several very important classes that are instantiated via Unity appear to have no instantiation as far as ReSharper can tell. If I followed the ReSharper recommendations I would get hosed!

LIMIT n,1 doesn't work in MS SQL Server. I think it's just about the only major database that doesn't support that syntax. To be fair, it isn't part of the SQL standard, although it is so widely supported that it should be. In everything except SQL server LIMIT works great. For SQL server, I haven't been able to find an elegant solution.

Try using SCP on Windows to transfer files, you can download SCP from Putty's website. Then try running:

pscp.exe filename.extension [email protected]:directory/subdirectory

There is a full length guide here.

viewNoteDateMonth.text  = [[displayDate objectAtIndex:2] uppercaseString];

Documentation: http://developer.apple.com/library/ios/documentation/Cocoa/Reference/Foundation/Classes/NSString_Class/Reference/NSString.html#//apple_ref/occ/instm/NSString/uppercaseString

You can also use lowercaseString and capitalizedString

You can create enums to deal with errors :)

enum RikhError: Error {
    case unknownError
    case connectionError
    case invalidCredentials
    case invalidRequest
    case notFound
    case invalidResponse
    case serverError
    case serverUnavailable
    case timeOut
    case unsuppotedURL
 }

and then create a method inside enum to receive the http response code and return the corresponding error in return :)

static func checkErrorCode(_ errorCode: Int) -> RikhError {
        switch errorCode {
        case 400:
            return .invalidRequest
        case 401:
            return .invalidCredentials
        case 404:
            return .notFound
        //bla bla bla
        default:
            return .unknownError
        }
    }

Finally update your failure block to accept single parameter of type RikhError :)

I use AngularJS v1.3.4

HTML:

<button ng-click="downloadPdf()" class="btn btn-primary">download PDF</button>

JS controller:

'use strict';
angular.module('xxxxxxxxApp')
    .controller('xxxxController', function ($scope, xxxxServicePDF) {
        $scope.downloadPdf = function () {
            var fileName = "test.pdf";
            var a = document.createElement("a");
            document.body.appendChild(a);
            a.style = "display: none";
            xxxxServicePDF.downloadPdf().then(function (result) {
                var file = new Blob([result.data], {type: 'application/pdf'});
                var fileURL = window.URL.createObjectURL(file);
                a.href = fileURL;
                a.download = fileName;
                a.click();
            });
        };
});

JS services:

angular.module('xxxxxxxxApp')
    .factory('xxxxServicePDF', function ($http) {
        return {
            downloadPdf: function () {
            return $http.get('api/downloadPDF', { responseType: 'arraybuffer' }).then(function (response) {
                return response;
            });
        }
    };
});

Java REST Web Services - Spring MVC:

@RequestMapping(value = "/downloadPDF", method = RequestMethod.GET, produces = "application/pdf")
    public ResponseEntity<byte[]> getPDF() {
        FileInputStream fileStream;
        try {
            fileStream = new FileInputStream(new File("C:\\xxxxx\\xxxxxx\\test.pdf"));
            byte[] contents = IOUtils.toByteArray(fileStream);
            HttpHeaders headers = new HttpHeaders();
            headers.setContentType(MediaType.parseMediaType("application/pdf"));
            String filename = "test.pdf";
            headers.setContentDispositionFormData(filename, filename);
            ResponseEntity<byte[]> response = new ResponseEntity<byte[]>(contents, headers, HttpStatus.OK);

If you wish to get the innerhtml of the class without the zend you could use this:

$dom = new DomDocument();
$dom->load($filePath);
$classname = 'main-article';
$finder = new DomXPath($dom);
$nodes = $finder->query("//*[contains(concat(' ', normalize-space(@class), ' '), ' $classname ')]");
$tmp_dom = new DOMDocument(); 
foreach ($nodes as $node) 
    {
    $tmp_dom->appendChild($tmp_dom->importNode($node,true));
    }
$innerHTML.=trim($tmp_dom->saveHTML()); 
echo $innerHTML;

Try ContentTemplate:

<Button Grid.Row="2" Grid.Column="0" Width="20" Height="20"
        Template="{StaticResource SomeTemplate}">
    <Button.ContentTemplate>
        <DataTemplate>
            <Image Source="../Folder1/Img1.png" Width="20" />
        </DataTemplate>
    </Button.ContentTemplate>
</Button>

For any of you still having problems as of Sept. 2012, go here: http://support.microsoft.com/kb/2527041 ...and grab the SQLManagementStudio_x(32|64)_ENU.exe (if you've already installed SQL Server 2008 Express R2), or SQL Server 2008 Express R2 with Tools, i.e. SQLEXPRWT_x64_ENU.exe or SQLEXPRWT_x32_ENU.exe (if you haven't).

From there, follow similar instructions as above (i.e. use the "Perform new installation and add shared features" selection, as "Management Tools - Basic" is considered a "shared feature"), if you've already installed SQL Server Express 2008 R2 (as I had). And if you haven't done that yet, then of course you're going to follow this way as you need to install the new instance anyway.

This solved things for me, and hopefully it will for you, too!

Another solution to handle this case is creating a customized Seekbar, to get ride of converting the real value and SeekBar progress every time:

import android.content.Context
import android.util.AttributeSet
import android.widget.SeekBar

//
// Require SeekBar with range [Min, Max] and INCREMENT value,
// However, Android Seekbar starts from 0 and increment is 1 by default, Android supports min attr on API 26,
// To make a increment & range Seekbar, we can do the following conversion:
//
//     seekbar.setMax((Max - Min) / Increment)
//     seekbar.setProgress((actualValue - Min) / Increment)
//     seekbar.getProgress = Min + (progress * Increment)
//
// The RangeSeekBar is responsible for handling all these logic inside the class.

data class Range(val min: Int, val max: Int, private val defaultIncrement: Int) {
    val increment = if ((max - min) < defaultIncrement) 1 else defaultIncrement
}


internal fun Range.toSeekbarMaximum(): Int = (max - min) / increment


class RangeSeekBar: SeekBar, SeekBar.OnSeekBarChangeListener {

    constructor(context: Context) : super(context)
    constructor(context: Context, attrs: AttributeSet) : super(context, attrs)

    var range: Range = Range(0, 100, 1)
        set(value) {
            field = value
            max = value.toSeekbarMaximum()
        }

    var value: Int = 0
        get() = range.min + progress * range.increment
        set(value) {
            progress = (value - range.min) / range.increment
            field = value
        }

    var onSeekBarChangeListenerDelegate: OnSeekBarChangeListener? = this

    override fun setOnSeekBarChangeListener(l: OnSeekBarChangeListener?) {
        onSeekBarChangeListenerDelegate = l
        super.setOnSeekBarChangeListener(this)
    }

    override fun onProgressChanged(seekBar: SeekBar?, progress: Int, fromUser: Boolean) {
        onSeekBarChangeListenerDelegate?.onProgressChanged(seekBar, value, fromUser)
    }

    override fun onStartTrackingTouch(seekBar: SeekBar?) {
        onSeekBarChangeListenerDelegate?.onStartTrackingTouch(seekBar)
    }

    override fun onStopTrackingTouch(seekBar: SeekBar?) {
        onSeekBarChangeListenerDelegate?.onStopTrackingTouch(seekBar)
    }
}

Then in your fragment,

    // init
    range_seekbar.range = Range(10, 110, 10)
    range_seekbar.value = 20

    // observe value changes
    range_seekbar.userChanges().skipInitialValue().subscribe {
        println("current value=$it")
    }

First create the duplicate database:

CREATE DATABASE duplicateddb;

Make sure the user and permissions are all in place and:

 mysqldump -u admin -p originaldb | mysql -u backup -pPassword duplicateddb; 

Use ModHeader Chrome extension.

Or you can try more complex value like Accept-Language: en-US,en;q=0.9,ru;q=0.8,th;q=0.7

This is for future readers. I found that the simplest method for me was to use Visual Studio -> Tools -> External Tools. More details in this answer.

Easier to use and good debugging tools.

While it's a bit more verbose, you can accomplish what everyone else was recommending underscore/lodash for 2 years ago, by using Array.prototype.reduce.

var subset = ['color', 'height'].reduce(function(o, k) { o[k] = elmo[k]; return o; }, {});

This approach solves it from the other side: rather than take an object and pass property names to it to extract, take an array of property names and reduce them into a new object.

While it's more verbose in the simplest case, a callback here is pretty handy, since you can easily meet some common requirements, e.g. change the 'color' property to 'colour' on the new object, flatten arrays, etc. -- any of the things you need to do when receiving an object from one service/library and building a new object needed somewhere else. While underscore/lodash are excellent, well-implemented libs, this is my preferred approach for less vendor-reliance, and a simpler, more consistent approach when my subset-building logic gets more complex.

edit: es7 version of the same:

const subset = ['color', 'height'].reduce((a, e) => (a[e] = elmo[e], a), {});

edit: A nice example for currying, too! Have a 'pick' function return another function.

const pick = (...props) => o => props.reduce((a, e) => ({ ...a, [e]: o[e] }), {});

The above is pretty close to the other method, except it lets you build a 'picker' on the fly. e.g.

pick('color', 'height')(elmo);

What's especially neat about this approach, is you can easily pass in the chosen 'picks' into anything that takes a function, e.g. Array#map:

[elmo, grover, bigBird].map(pick('color', 'height'));
// [
//   { color: 'red', height: 'short' },
//   { color: 'blue', height: 'medium' },
//   { color: 'yellow', height: 'tall' },
// ]

You use the datetime.datetime.date() method:

datetime.datetime.now().date()

Obviously, the expression above can (and should IMHO :) be written as:

datetime.date.today()

How can I send my $scope object from one controller to another using .$emit and .$on methods?

You can send any object you want within the hierarchy of your app, including $scope.

Here is a quick idea about how broadcast and emit work.

Notice the nodes below; all nested within node 3. You use broadcast and emit when you have this scenario.

Note: The number of each node in this example is arbitrary; it could easily be the number one; the number two; or even the number 1,348. Each number is just an identifier for this example. The point of this example is to show nesting of Angular controllers/directives.

                 3
           ------------
           |          |
         -----     ------
         1   |     2    |
      ---   ---   ---  ---
      | |   | |   | |  | |

Check out this tree. How do you answer the following questions?

Note: There are other ways to answer these questions, but here we'll discuss broadcast and emit. Also, when reading below text assume each number has it's own file (directive, controller) e.x. one.js, two.js, three.js.

How does node 1 speak to node 3?

In file one.js

scope.$emit('messageOne', someValue(s));

In file three.js - the uppermost node to all children nodes needed to communicate.

scope.$on('messageOne', someValue(s));

How does node 2 speak to node 3?

In file two.js

scope.$emit('messageTwo', someValue(s));

In file three.js - the uppermost node to all children nodes needed to communicate.

scope.$on('messageTwo', someValue(s));

How does node 3 speak to node 1 and/or node 2?

In file three.js - the uppermost node to all children nodes needed to communicate.

scope.$broadcast('messageThree', someValue(s));

In file one.js && two.js whichever file you want to catch the message or both.

scope.$on('messageThree', someValue(s));

How does node 2 speak to node 1?

In file two.js

scope.$emit('messageTwo', someValue(s));

In file three.js - the uppermost node to all children nodes needed to communicate.

scope.$on('messageTwo', function( event, data ){
  scope.$broadcast( 'messageTwo', data );
});

In file one.js

scope.$on('messageTwo', someValue(s));

HOWEVER

When you have all these nested child nodes trying to communicate like this, you will quickly see many $on's, $broadcast's, and $emit's.

Here is what I like to do.

In the uppermost PARENT NODE ( 3 in this case... ), which may be your parent controller...

So, in file three.js

scope.$on('pushChangesToAllNodes', function( event, message ){
  scope.$broadcast( message.name, message.data );
});

Now in any of the child nodes you only need to $emit the message or catch it using $on.

NOTE: It is normally quite easy to cross talk in one nested path without using $emit, $broadcast, or $on, which means most use cases are for when you are trying to get node 1 to communicate with node 2 or vice versa.

How does node 2 speak to node 1?

In file two.js

scope.$emit('pushChangesToAllNodes', sendNewChanges());

function sendNewChanges(){ // for some event.
  return { name: 'talkToOne', data: [1,2,3] };
}

In file three.js - the uppermost node to all children nodes needed to communicate.

We already handled this one remember?

In file one.js

scope.$on('talkToOne', function( event, arrayOfNumbers ){
  arrayOfNumbers.forEach(function(number){
    console.log(number);
  });
});

You will still need to use $on with each specific value you want to catch, but now you can create whatever you like in any of the nodes without having to worry about how to get the message across the parent node gap as we catch and broadcast the generic pushChangesToAllNodes.

Hope this helps...

I'm assuming you have multiple markers that you wish to display on a google map.

The solution is two parts, one to create and populate an array containing all the details of the markers, then a second to loop through all entries in the array to create each marker.

Not know what environment you're using, it's a little difficult to provide specific help.

My best advice is to take a look at this article & accepted answer to understand the principals of creating a map with multiple markers: Display multiple markers on a map with their own info windows

I think this will work perfectly. I used the same:

For Android Studio:

1. Click on Build > Generate Signed APK.
2. You will get a message box, just click OK.
3. Now there will be another window just copy Key Store Path.
4. Now open a command prompt and go to C:\Program Files\Java\jdk1.6.0_39\bin> (or any installed jdk version).
5. Type keytool -list -v -keystore and then paste your Key Store Path (Eg. C:\Program Files\Java\jdk1.6.0_39\bin>keytool -list -v -keystore "E:\My Projects \Android\android studio\signed apks\Hello World\HelloWorld.jks").
6. Now it will Ask Key Store Password, provide yours and press Enter to get your SHA1 and MD5 Certificate keys.

JSONObject class has a method named "has":

http://developer.android.com/reference/org/json/JSONObject.html#has(java.lang.String)

Returns true if this object has a mapping for name. The mapping may be NULL.

Considering that we have Set<String> stringSet we can use following:

Plain Java

List<String> strList = new ArrayList<>(stringSet);

Guava

List<String> strList = Lists.newArrayList(stringSet);

Apache Commons

List<String> strList = new ArrayList<>();
CollectionUtils.addAll(strList, stringSet);

Java 10 (Unmodifiable List)

List<String> strList = List.copyOf(stringSet);
List<String> strList = stringSet.stream().collect(Collectors.toUnmodifiableList());

Java 8 (Modifiable Lists)

import static java.util.stream.Collectors.*;
List<String> stringList1 = stringSet.stream().collect(toList());

As per the doc for the method toList()

There are no guarantees on the type, mutability, serializability, or thread-safety of the List returned; if more control over the returned List is required, use toCollection(Supplier).

So if we need a specific implementation e.g. ArrayList we can get it this way:

List<String> stringList2 = stringSet.stream().
                              collect(toCollection(ArrayList::new));

Java 8 (Unmodifiable Lists)

We can make use of Collections::unmodifiableList method and wrap the list returned in previous examples. We can also write our own custom method as:

class ImmutableCollector {
    public static <T> Collector<T, List<T>, List<T>> toImmutableList(Supplier<List<T>> supplier) {
            return Collector.of( supplier, List::add, (left, right) -> {
                        left.addAll(right);
                        return left;
                    }, Collections::unmodifiableList);
        }
}

And then use it as:

List<String> stringList3 = stringSet.stream()
             .collect(ImmutableCollector.toImmutableList(ArrayList::new)); 

Another possibility is to make use of collectingAndThen method which allows some final transformation to be done before returning result:

    List<String> stringList4 = stringSet.stream().collect(collectingAndThen(
      toCollection(ArrayList::new),Collections::unmodifiableList));

One point to note is that the method Collections::unmodifiableList returns an unmodifiable view of the specified list, as per doc. An unmodifiable view collection is a collection that is unmodifiable and is also a view onto a backing collection. Note that changes to the backing collection might still be possible, and if they occur, they are visible through the unmodifiable view. But the collector method Collectors.unmodifiableList returns truly immutable list in Java 10.

Each tablespace has one or more datafiles that it uses to store data.

The max size of a datafile depends on the block size of the database. I believe that, by default, that leaves with you with a max of 32gb per datafile.

To find out if the actual limit is 32gb, run the following:

select value from v$parameter where name = 'db_block_size';

Compare the result you get with the first column below, and that will indicate what your max datafile size is.

I have Oracle Personal Edition 11g r2 and in a default install it had an 8,192 block size (32gb per data file).

Block Sz   Max Datafile Sz (Gb)   Max DB Sz (Tb)

--------   --------------------   --------------

   2,048                  8,192          524,264

   4,096                 16,384        1,048,528

   8,192                 32,768        2,097,056

  16,384                 65,536        4,194,112

  32,768                131,072        8,388,224

You can run this query to find what datafiles you have, what tablespaces they are associated with, and what you've currrently set the max file size to (which cannot exceed the aforementioned 32gb):

select bytes/1024/1024 as mb_size,
       maxbytes/1024/1024 as maxsize_set,
       x.*
from   dba_data_files x

MAXSIZE_SET is the maximum size you've set the datafile to. Also relevant is whether you've set the AUTOEXTEND option to ON (its name does what it implies).

If your datafile has a low max size or autoextend is not on you could simply run:

alter database datafile 'path_to_your_file\that_file.DBF' autoextend on maxsize unlimited;

However if its size is at/near 32gb an autoextend is on, then yes, you do need another datafile for the tablespace:

alter tablespace system add datafile 'path_to_your_datafiles_folder\name_of_df_you_want.dbf' size 10m autoextend on maxsize unlimited;

You might find this wiki article interesting : http://ajaxpatterns.org/On-Demand_Javascript

It explains how and when to use such technique.

Here's how you can specify that with find:

find . -type f -name "*_peaks.bed" ! -path "./tmp/*" ! -path "./scripts/*"

Explanation:

• find . - Start find from current working directory (recursively by default)
• -type f - Specify to find that you only want files in the results
• -name "*_peaks.bed" - Look for files with the name ending in _peaks.bed
• ! -path "./tmp/*" - Exclude all results whose path starts with ./tmp/
• ! -path "./scripts/*" - Also exclude all results whose path starts with ./scripts/

Testing the Solution:

$ mkdir a b c d e
$ touch a/1 b/2 c/3 d/4 e/5 e/a e/b
$ find . -type f ! -path "./a/*" ! -path "./b/*"

./d/4
./c/3
./e/a
./e/b
./e/5

You were pretty close, the -name option only considers the basename, where as -path considers the entire path =)

1. I had the same problem, and I used the UTF-8 coding for both of my files as follows:

   add @charset "UTF-8"; in CSS file and <meta charset="UTF-8"> under <head> tag in HTML file. and it worked for me.

   it makes the same encoding for both the files i.e HTML and CSS.

   You can also do the same for "UTF-16" encoding.

2. If it is still not working check for the <link type="text/css" rel="stylesheet" href="style.css"/> under <head> tag in HTML File where you should mention type="text/css"

You can use sqlcmd to run a backup, or any other T-SQL script. You can find the detailed instructions and examples on various useful sqlcmd switches in this article: Working with the SQL Server command line (sqlcmd)

getline(fin, buffer, '\n')
where fin is opened file(ifstream object) and buffer is of string/char type where you want to copy line.

My error was in a xml drawable file. I had the first liner duplicate. Changing it to this worked for me:

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

While not directly related to the question's environment, just for the curiosity, I did the same test on .NET Core 2.1, x64, release mode.

Here is the interesting result, confirming similar phonomena (other way around) happening over the dark side of the force. Code:

static void Main(string[] args)
{
    Stopwatch watch = new Stopwatch();

    Console.WriteLine("2 * (i * i)");

    for (int a = 0; a < 10; a++)
    {
        int n = 0;

        watch.Restart();

        for (int i = 0; i < 1000000000; i++)
        {
            n += 2 * (i * i);
        }

        watch.Stop();

        Console.WriteLine($"result:{n}, {watch.ElapsedMilliseconds} ms");
    }

Here's what u can also try....

run your application....while it is still running launch your command prompt

while your application is running type netstat -n on the command prompt. You should see a list of TCP/IP connections. Check if your list is not very long. Ideally you should have less than 5 connections in the list. Check the status of the connections.
If you have too many connections with a TIME_WAIT status it means the connection has been closed and is waiting for the OS to release the resources. If you are running on Windows, the default ephemeral port rang is between 1024 and 5000 and the default time it takes Windows to release the resource from TIME_WAIT status is 4 minutes. So if your application used more then 3976 connections in less then 4 minutes, you will get the exception you got.

Suggestions to fix it:

1. Add a connection pool to your connection string.

If you continue to receive the same error message (which is highly unlikely) you can then try the following: (Please don't do it if you are not familiar with the Windows registry)

1. Run regedit from your run command. In the registry editor look for this registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters:

Modify the settings so they read:

MaxUserPort = dword:00004e20 (10,000 decimal) TcpTimedWaitDelay = dword:0000001e (30 decimal)

This will increase the number of ports to 10,000 and reduce the time to release freed tcp/ip connections.

Only use suggestion 2 if 1 fails.

Thank you.

While most people blindly follow the advice of the javadoc, there are very specific situations where you want to actually avoid toString(). For example, I'm using enums in my Java code, but they need to be serialized to a database, and back again. If I used toString() then I would technically be subject to getting the overridden behavior as others have pointed out.

Additionally one can also de-serialize from the database, for example, this should always work in Java:

MyEnum taco = MyEnum.valueOf(MyEnum.TACO.name());

Whereas this is not guaranteed:

MyEnum taco = MyEnum.valueOf(MyEnum.TACO.toString());

By the way, I find it very odd for the Javadoc to explicitly say "most programmers should". I find very little use-case in the toString of an enum, if people are using that for a "friendly name" that's clearly a poor use-case as they should be using something more compatible with i18n, which would, in most cases, use the name() method.

A Web server exclusively handles HTTP/HTTPS requests. It serves content to the web using HTTP/HTTPS protocol.

An application server serves business logic to application programs through any number of protocols, possibly including HTTP. The application program can use this logic just as it would call a method on an object. In most cases, the server exposes this business logic through a component API, such as the EJB (Enterprise JavaBean) component model found on Java EE (Java Platform, Enterprise Edition) application servers. The main point is that the web server exposes everything through the http protocol, while the application server is not restricted to it. An application server thus offers much more services than an web server which typically include:

• A (proprietary or not) API
• Load balancing, fail over...
• Object life cycle management
• State management (session)
• Resource management (e.g. connection pools to database)

Most of the application servers have Web Server as integral part of them, that means App Server can do whatever Web Server is capable of. Additionally App Server have components and features to support Application level services such as Connection Pooling, Object Pooling, Transaction Support, Messaging services etc.

An application server can (but doesn't always) run on a web server to execute program logic, the results of which can then be delivered by the web server. That's one example of a web server/application server scenario. A good example in the Microsoft world is the Internet Information Server / SharePoint Server relationship. IIS is a web server; SharePoint is an application server. SharePoint sits "on top" of IIS, executes specific logic, and serves the results via IIS. In the Java world, there's a similar scenario with Apache and Tomcat, for example.

As web servers are well suited for static content and app servers for dynamic content, most of the production environments have web server acting as reverse proxy to app server. That means while service a page request, static contents such as images/Static html is served by web server that interprets the request. Using some kind of filtering technique (mostly extension of requested resource) web server identifies dynamic content request and transparently forwards to app server.

Example of such configuration is Apache HTTP Server and BEA WebLogic Server. Apache HTTP Server is Web Server and BEA WebLogic is Application Server. In some cases, the servers are tightly integrated such as IIS and .NET Runtime. IIS is web server. when equipped with .NET runtime environment IIS is capable of providing application services

It's easy to create this yourself

In your layout include the following ProgressBar with a specific drawable (note you should get the width from dimensions instead). The max value is important here:

<ProgressBar
    android:id="@+id/progressBar"
    style="?android:attr/progressBarStyleHorizontal"
    android:layout_width="150dp"
    android:layout_height="150dp"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    android:max="500"
    android:progress="0"
    android:progressDrawable="@drawable/circular" />

Now create the drawable in your resources with the following shape. Play with the radius (you can use innerRadius instead of innerRadiusRatio) and thickness values.

circular (Pre Lollipop OR API Level < 21)

   <shape
        android:innerRadiusRatio="2.3"
        android:shape="ring"
        android:thickness="3.8sp" >
        <solid android:color="@color/yourColor" />
   </shape>

circular ( >= Lollipop OR API Level >= 21)

    <shape
        android:useLevel="true"
        android:innerRadiusRatio="2.3"
        android:shape="ring"
        android:thickness="3.8sp" >
        <solid android:color="@color/yourColor" />
     </shape>

useLevel is "false" by default in API Level 21 (Lollipop) .

Start Animation

Next in your code use an ObjectAnimator to animate the progress field of the ProgessBar of your layout.

ProgressBar progressBar = (ProgressBar) view.findViewById(R.id.progressBar);
ObjectAnimator animation = ObjectAnimator.ofInt(progressBar, "progress", 0, 500); // see this max value coming back here, we animate towards that value
animation.setDuration(5000); // in milliseconds
animation.setInterpolator(new DecelerateInterpolator());
animation.start();

Stop Animation

progressBar.clearAnimation();

P.S. unlike examples above, it give smooth animation.

Try the nbopen module. When you install and integrate it with the windows explorer, you will be able to open any notebook by double clicking on it.

but I can't initialize my derived class, I mean I did this Inheritance so I can add animals to my PetStore but now since sizeF is private how can I do that ?? so I'm thinking maybe in the PetStore default constructor I can call Farm()... so any Idea ???

Don't panic.

Farm constructor will be called in the constructor of PetStore, automatically.

See the base class inheritance calling rules: What are the rules for calling the superclass constructor?

In addition to James's answer:

If you need to disable the link use

$('a[data-toggle="tab"]').addClass('disabled');

If you need to prevent a disabled link from loading the tab

$('a[data-toggle="tab"]').click(function(e){

            if($this.hasClass("disabled")){

                e.preventDefault();

                e.stopPropagation();

                e.stopImmediatePropagation();

                return false;

            }
}

If you need to unable the link

$('a[data-toggle="tab"]').removeClass('disabled');

I was having the same problem, until just now.

Removing the / from before /css/app.css so that its css.app.css worked for me.

I'm surprised Object.assign hasn't been mentioned.

let cloned = Object.assign({}, source);

If available (e.g. Babel), you can use the object spread operator:

let cloned = { ... source };

just use a z-index and everything will sit nice. make sure to have positions marked as fixed or absolute. then nothing will move around like with a float tag.

You need to call the AddAddress method once for every recipient. Like so:

$mail->AddAddress('[email protected]', 'Person One');
$mail->AddAddress('[email protected]', 'Person Two');
// ..

To make things easy, you should loop through an array to do this.

$recipients = array(
   '[email protected]' => 'Person One',
   '[email protected]' => 'Person Two',
   // ..
);
foreach($recipients as $email => $name)
{
   $mail->AddAddress($email, $name);
}

Better yet, add them as Carbon Copy recipients.

$mail->AddCC('[email protected]', 'Person One');
$mail->AddCC('[email protected]', 'Person Two');
// ..

To make things easy, you should loop through an array to do this.

$recipients = array(
   '[email protected]' => 'Person One',
   '[email protected]' => 'Person Two',
   // ..
);
foreach($recipients as $email => $name)
{
   $mail->AddCC($email, $name);
}

You can create a reference to the enum in your component class (I just changed the initial character to be lower-case) and then use that reference from the template (plunker):

import {Component} from 'angular2/core';

enum CellType {Text, Placeholder}
class Cell {
  constructor(public text: string, public type: CellType) {}
}
@Component({
  selector: 'my-app',
  template: `
    <div [ngSwitch]="cell.type">
      <div *ngSwitchCase="cellType.Text">
        {{cell.text}}
      </div>
      <div *ngSwitchCase="cellType.Placeholder">
        Placeholder
      </div>
    </div>
    <button (click)="setType(cellType.Text)">Text</button>
    <button (click)="setType(cellType.Placeholder)">Placeholder</button>
  `,
})
export default class AppComponent {

  // Store a reference to the enum
  cellType = CellType;
  public cell: Cell;

  constructor() {
    this.cell = new Cell("Hello", CellType.Text)
  }

  setType(type: CellType) {
    this.cell.type = type;
  }
}

I did it only using boostrap, you must be very careful in the location of the row and the column, here is my example.

<section>_x000D_
<div class="container">_x000D_
        <div ng-app="myApp">_x000D_
        _x000D_
                <div ng-controller="SubregionController">_x000D_
                    <div class="row text-center">_x000D_
                        <div class="col-md-4" ng-repeat="post in posts">_x000D_
                            <div >_x000D_
                                <div>{{post.title}}</div>_x000D_
                            </div>_x000D_
                        </div>_x000D_
                    _x000D_
                    </div>_x000D_
                </div>        _x000D_
        </div>_x000D_
    </div>_x000D_
</div> _x000D_
_x000D_
</section>

Wikipedia, of all places, actually discusses this.

The idea is to make sure all package names are unique world-wide, by having authors use a variant of a DNS name they own to name the package. For example, the owners of the domain name joda.org created a number of packages whose names begin with org.joda, for example:

• org.joda.time
• org.joda.time.base
• org.joda.time.chrono
• org.joda.time.convert
• org.joda.time.field
• org.joda.time.format

I have nice solution that i would like to share. First you need to detect if user is on mobile like this:

var touchDevice = /ipad|iphone|android|windows phone|blackberry/i.test(navigator.userAgent.toLowerCase());

Then just add:

if (!touchDevice) {
    $(".navbar-ul").addClass("hoverable");
}

And in CSS:

.navbar-ul.hoverable li a:hover {
    color: #fff;
}

You can use str_match_all, with a regular expression that would identify your words. The following works with initial, final and duplicated spaces.

library(stringr)
s <-  "
  Day after day, day after day,
  We stuck, nor breath nor motion;
"
m <- str_match_all( s, "\\S+" )  # Sequences of non-spaces
length(m[[1]])

Mr. Curious was curious about this as well. In addition to the #>> '{}' operator, in 9.6+ one can get the value of a jsonb string with the ->> operator:

select to_jsonb('Some "text"'::TEXT)->>0;
  ?column?
-------------
 Some "text"
(1 row)

If one has a json value, then the solution is to cast into jsonb first:

select to_json('Some "text"'::TEXT)::jsonb->>0;
  ?column?
-------------
 Some "text"
(1 row)

In my case, I needed to allow many inactives and only one combination of two keys active, like this:

UUL_USR_IDF  UUL_UND_IDF    UUL_ATUAL
137          18             0
137          19             0
137          20             1
137          21             0

This seems to work:

CREATE UNIQUE NONCLUSTERED INDEX UQ_USR_UND_UUL_USR_IDF_UUL_ATUAL
ON USER_UND(UUL_USR_IDF, UUL_ATUAL)
WHERE UUL_ATUAL = 1;

Here are my test cases:

SELECT * FROM USER_UND WHERE UUL_USR_IDF = 137

insert into USER_UND values (137, 22, 1) --I CAN NOT => Cannot insert duplicate key row in object 'dbo.USER_UND' with unique index 'UQ_USR_UND_UUL_USR_IDF_UUL_ATUAL'. The duplicate key value is (137, 1).
insert into USER_UND values (137, 23, 0) --I CAN
insert into USER_UND values (137, 24, 0) --I CAN

DELETE FROM USER_UND WHERE UUL_USR_ID = 137

insert into USER_UND values (137, 22, 1) --I CAN
insert into USER_UND values (137, 27, 1) --I CAN NOT => Cannot insert duplicate key row in object 'dbo.USER_UND' with unique index 'UQ_USR_UND_UUL_USR_IDF_UUL_ATUAL'. The duplicate key value is (137, 1).
insert into USER_UND values (137, 28, 0) --I CAN
insert into USER_UND values (137, 29, 0) --I CAN

The linked list holds operations on the shared data structure.

For example, if I have a stack, it will be manipulated with pushes and pops. The linked list would be a set of pushes and pops on the pseudo-shared stack. Each thread sharing that stack will actually have a local copy, and to get to the current shared state, it'll walk the linked list of operations, and apply each operation in order to its local copy of the stack. When it reaches the end of the linked list, its local copy holds the current state (though, of course, it's subject to becoming stale at any time).

In the traditional model, you'd have some sort of locks around each push and pop. Each thread would wait to obtain a lock, then do a push or pop, then release the lock.

In this model, each thread has a local snapshot of the stack, which it keeps synchronized with other threads' view of the stack by applying the operations in the linked list. When it wants to manipulate the stack, it doesn't try to manipulate it directly at all. Instead, it simply adds its push or pop operation to the linked list, so all the other threads can/will see that operation and they can all stay in sync. Then, of course, it applies the operations in the linked list, and when (for example) there's a pop it checks which thread asked for the pop. It uses the popped item if and only if it's the thread that requested this particular pop.

the other answers should work. however I wanna mention

from java doc:

FileWriter is meant for writing streams of characters. For writing streams of raw bytes, consider using a FileOutputStream.

reading your method codes, you are about to write String to the file, what you were doing is convert String to raw bytes, then write so I think using FileWriter is not a bad idea.

And for the newline problem, Writer has method .write(String), which is convenient to use.

How i solved

# yum update
# yum install -y https://centos7.iuscommunity.org/ius-release.rpm
# yum install -y python36u python36u-libs python36u-devel python36u-pip
# pip3.6 install pipenv

I hope it will help Someone to resolve "gcc" issue.

This error message seems to come up in various situations.

In my case, on top of my application's Web.Config file I had an extra Web.Config file in the root folder (C:\Inetpub\www.root). Probably left there after some testing, I had forgotten all about it, and couldn't figure out what the problem was.

Removing it solved the problem for me.

My solution is:

import os
print(os.path.dirname(os.path.abspath(__file__)))

I wanted to make a version of this that uses $.getJSON() from a separate JSON file.

Demo: here

JavaScript:

$(document).ready(function () {
    "use strict";

    var selectData, $states;

    function updateSelects() {
        var cities = $.map(selectData[this.value], function (city) {
            return $("<option />").text(city);
        });
        $("#city_names").empty().append(cities);
    }

    $.getJSON("updateSelect.json", function (data) {
        var state;
        selectData = data;
        $states = $("#us_states").on("change", updateSelects);
        for (state in selectData) {
            $("<option />").text(state).appendTo($states);
        }
        $states.change();
    });
});

HTML:

<!DOCTYPE html>
<html>
<head>
    <title></title>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>

    <select id="us_states"></select>
    <select id="city_names"></select>
    <script type="text/javascript" src="updateSelect.js"></script>

</html>

JSON:

{
    "NE": [
        "Smallville",
        "Bigville"
    ],
    "CA": [
        "Sunnyvale",
        "Druryburg",
        "Vickslake"
    ],

}

Based on drspaceboo's solution, with Kotlin you can use an extension to convert Float to dips more easily.

fun Float.toDips() =
        TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, this, resources.displayMetrics);

Usage:

(65f).toDips()

>>> x = "2342.34"
>>> float(x)
2342.3400000000001

There you go. Use float (which behaves like and has the same precision as a C,C++, or Java double).

                        }
                    }
                });



    }
    }

    document.getElementById("something").innerHTML = "<img src=\"something\" onmouseover=\"change('ex1')\" />";

OR

    document.getElementById("something").innerHTML = '<img src="something" onmouseover="change(\'ex1\')" />';

It should be working...

That's because although a Customer is an Object, a List of Customers is not a List of Objects. If it was, then you could put any object in a list of Customers.

It is really very disappointing that you can't do it with styles (<item name="android:textAllCaps">true</item>) or on each XML layout file with the textAllCaps attribute, and the only way to do it is actually using theString.toUpperCase() on each of the strings when you do a textViewXXX.setText(theString).

In my case, I did not wanted to have theString.toUpperCase() everywhere in my code but to have a centralized place to do it because I had some Activities and lists items layouts with TextViews that where supposed to be capitalized all the time (a title) and other who did not... so... some people may think is an overkill, but I created my own CapitalizedTextView class extending android.widget.TextView and overrode the setText method capitalizing the text on the fly.

At least, if the design changes or I need to remove the capitalized text in future versions, I just need to change to normal TextView in the layout files.

Now, take in consideration that I did this because the App's Designer actually wanted this text (the titles) in CAPS all over the App no matter the original content capitalization, and also I had other normal TextViews where the capitalization came with the the actual content.

This is the class:

package com.realactionsoft.android.widget;

import android.content.Context; 
import android.util.AttributeSet; 
import android.view.ViewTreeObserver; 
import android.widget.TextView;


public class CapitalizedTextView extends TextView implements ViewTreeObserver.OnPreDrawListener {

    public CapitalizedTextView(Context context) {
        super(context);
    }

    public CapitalizedTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CapitalizedTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public void setText(CharSequence text, BufferType type) {
        super.setText(text.toString().toUpperCase(), type);
    }

}

And whenever you need to use it, just declare it with all the package in the XML layout:

<com.realactionsoft.android.widget.CapitalizedTextView 
        android:id="@+id/text_view_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

Some will argue that the correct way to style text on a TextView is to use a SpannableString, but I think that would be even a greater overkill, not to mention more resource-consuming because you'll be instantiating another class than TextView.

If you use sufficiently big list not in b clause will do a linear search for each of the item in a. Why not use set? Set takes iterable as parameter to create a new set object.

>>> a = ["a", "b", "c", "d", "e"]
>>> b = ["c", "d", "f", "g"]
>>> set(a).intersection(set(b))
{'c', 'd'}

You can also make a simple function in first level derived class, to call grand base function

You can also use joblib.dump and joblib.load which is much more efficient at handling numerical arrays than the default python pickler.

Joblib is included in scikit-learn:

>>> import joblib
>>> from sklearn.datasets import load_digits
>>> from sklearn.linear_model import SGDClassifier

>>> digits = load_digits()
>>> clf = SGDClassifier().fit(digits.data, digits.target)
>>> clf.score(digits.data, digits.target)  # evaluate training error
0.9526989426822482

>>> filename = '/tmp/digits_classifier.joblib.pkl'
>>> _ = joblib.dump(clf, filename, compress=9)

>>> clf2 = joblib.load(filename)
>>> clf2
SGDClassifier(alpha=0.0001, class_weight=None, epsilon=0.1, eta0=0.0,
       fit_intercept=True, learning_rate='optimal', loss='hinge', n_iter=5,
       n_jobs=1, penalty='l2', power_t=0.5, rho=0.85, seed=0,
       shuffle=False, verbose=0, warm_start=False)
>>> clf2.score(digits.data, digits.target)
0.9526989426822482

Edit: in Python 3.8+ it's now possible to use pickle for efficient pickling of object with large numerical arrays as attributes if you use pickle protocol 5 (which is not the default).

define() is part of the AMD spec of js

See:

• https://github.com/amdjs/amdjs-api/wiki/AMD

Edit: Also see Claudio's answer below. Likely the more relevant explanation.

But if we write it ourselves, that constructor is called automatically.

That's not correct. The no-args constructor is called if you call it, and regardless of whether or not you wrote it yourself. It is also called automatically if you don't code an explicit super(...) call in a derived class.

None of this constitutes constructor overriding. There is no such thing in Java. There is constructor overloading, i.e. providing different argument sets.

if you have many networks attached to you OS, yo must especify one of this network in the bind-addres from my.conf file. an example:

[mysqld]
bind-address = 127.100.10.234

this ip is from a ethX configuration.

cygwin is another option. It has a port of svn.

Even though this is an old thread, I thought I would weigh in as I had to deal with this lately.

You should not use rowCount for SELECT statements as it is not portable. I use the isset function to test if a select statement worked:

$today = date('Y-m-d', strtotime('now'));

$sth = $db->prepare("SELECT id_email FROM db WHERE hardcopy = '1' AND hardcopy_date <= :today AND hardcopy_sent = '0' ORDER BY id_email ASC");

//I would usually put this all in a try/catch block, but kept it the same for continuity
if(!$sth->execute(array(':today'=>$today))) 
{
    $db = null ;
    exit();
}

$result = $sth->fetch(PDO::FETCH_OBJ)

if(!isset($result->id_email))
{
    echo "empty";
}
else
{
    echo "not empty, value is $result->id_email";
}

$db = null;

Of course this is only for a single result, as you might have when looping over a dataset.

You can see the default value in Chrome in this link

int64_t g_used_idle_socket_timeout_s = 300 // 5 minutes

In Chrome, as far as I know, there isn't an easy way (as Firefox do) to change the timeout value.

Python implimentation Origin is the center of the contiguous United States.

from haversine import haversine
origin = (39.50, 98.35)
paris = (48.8567, 2.3508)
haversine(origin, paris, miles=True)

To get the answer in kilometers simply set miles=false.

DECIMAL_DIG from <float.h> should give at least a reasonable approximation of that. Since that deals with decimal digits, and it's really stored in binary, you can probably store something a little larger without losing precision, but exactly how much is hard to say. I suppose you should be able to figure it out from FLT_RADIX and DBL_MANT_DIG, but I'm not sure I'd completely trust the result.

You can just:

var f = new Date(from.split('-').reverse().join('/'));

You just simply needs to add JAVA_HOME environment variable and provide the complete path of the latest JDK folder on your computer.

Re launch the installer and it would work.

You may use jQuery in it like

$('#yesh').click(function(){
     *****HERE GOES THE FUNCTION*****
});

Besides jQuery is easy to use.

You can make changes in colors etc using simple jQUery or Javascript.

Check out Google's Gson: http://code.google.com/p/google-gson/

From their website:

Gson gson = new Gson(); // Or use new GsonBuilder().create();
MyType target2 = gson.fromJson(json, MyType.class); // deserializes json into target2

You would just need to make a MyType class (renamed, of course) with all the fields in the json string. It might get a little more complicated when you're doing the arrays, if you prefer to do all of the parsing manually (also pretty easy) check out http://www.json.org/ and download the Java source for the Json parser objects.

A while ago i wrote a detailed article about Hibernate key generators: http://blog.eyallupu.com/2011/01/hibernatejpa-identity-generators.html

Choosing the correct generator is a complicated task but it is important to try and get it right as soon as possible - a late migration might be a nightmare.

A little off topic but a good chance to raise a point usually overlooked which is sharing keys between applications (via API). Personally I always prefer surrogate keys and if I need to communicate my objects with other systems I don't expose my key (even though it is a surrogate one) – I use an additional ‘external key’. As a consultant I have seen more than once 'great' system integrations using object keys (the 'it is there let's just use it' approach) just to find a year or two later that one side has issues with the key range or something of the kind requiring a deep migration on the system exposing its internal keys. Exposing your key means exposing a fundamental aspect of your code to external constrains shouldn’t really be exposed to.

Just setup the master repo, was excited to see that we have a download progress, see screenshot ;)

CocoaPods release 1.2.0 (Jan 28) fixes this issue, thanks to all contributors and Danielle Tomlinson for this release.

requests library doesn't support ftp links.

To download a file from FTP server you could:

import urllib 

urllib.urlretrieve('ftp://server/path/to/file', 'file')
# if you need to pass credentials:
#   urllib.urlretrieve('ftp://username:password@server/path/to/file', 'file')

Or:

import shutil
import urllib2
from contextlib import closing

with closing(urllib2.urlopen('ftp://server/path/to/file')) as r:
    with open('file', 'wb') as f:
        shutil.copyfileobj(r, f)

Python3:

import shutil
import urllib.request as request
from contextlib import closing

with closing(request.urlopen('ftp://server/path/to/file')) as r:
    with open('file', 'wb') as f:
        shutil.copyfileobj(r, f)

your_list = [None]*size_required

Add the marker to the map like this

Marker markerName = map.addMarker(new MarkerOptions().position(latLng).title("Title"));

Then you'll be able to use the remove method, it will remove only that marker

markerName.remove();

Depending on how large and how well-written the original code was, it might be worth starting again in your favourite language (which might still be C++) and learning from any mistakes made in the last version. Didn't someone once say about writing one to throw away?

n.b. Clearly if this is a huge product, then it may not be worth the time.

Use dispatch group

dispatchGroup.enter()
FirstOperation(completion: { _ in
    dispatchGroup.leave()

dispatchGroup.enter()
SecondOperation(completion: { _ in

})
dispatchGroup.wait() // Waits here on this thread until the two operations complete executing.

To gain access for other users to your local machine, i usually use ngrok. Ngrok exposes your localhost to the web, and has an NPM wrapper that is simple to install and start:

$ npm install ngrok -g
$ ngrok http 3000

See this example usage:

In the above example, the locally running instance of sails at: localhost:3000 is now available on the Internet served at: http://69f8f0ee.ngrok.io or https://69f8f0ee.ngrok.io

In addition to the already posted answer, I thought I should share a handy trick I use to load all the DLL functions into the program through function pointers, without writing a separate GetProcAddress call for each and every function. I also like to call the functions directly as attempted in the OP.

Start by defining a generic function pointer type:

typedef int (__stdcall* func_ptr_t)();

What types that are used aren't really important. Now create an array of that type, which corresponds to the amount of functions you have in the DLL:

func_ptr_t func_ptr [DLL_FUNCTIONS_N];

In this array we can store the actual function pointers that point into the DLL memory space.

Next problem is that GetProcAddress expects the function names as strings. So create a similar array consisting of the function names in the DLL:

const char* DLL_FUNCTION_NAMES [DLL_FUNCTIONS_N] = 
{
  "dll_add",
  "dll_subtract",
  "dll_do_stuff",
  ...
};

Now we can easily call GetProcAddress() in a loop and store each function inside that array:

for(int i=0; i<DLL_FUNCTIONS_N; i++)
{
  func_ptr[i] = GetProcAddress(hinst_mydll, DLL_FUNCTION_NAMES[i]);

  if(func_ptr[i] == NULL)
  {
    // error handling, most likely you have to terminate the program here
  }
}

If the loop was successful, the only problem we have now is calling the functions. The function pointer typedef from earlier isn't helpful, because each function will have its own signature. This can be solved by creating a struct with all the function types:

typedef struct
{
  int  (__stdcall* dll_add_ptr)(int, int);
  int  (__stdcall* dll_subtract_ptr)(int, int);
  void (__stdcall* dll_do_stuff_ptr)(something);
  ...
} functions_struct;

And finally, to connect these to the array from before, create a union:

typedef union
{
  functions_struct  by_type;
  func_ptr_t        func_ptr [DLL_FUNCTIONS_N];
} functions_union;

Now you can load all the functions from the DLL with the convenient loop, but call them through the by_type union member.

But of course, it is a bit burdensome to type out something like

functions.by_type.dll_add_ptr(1, 1); whenever you want to call a function.

As it turns out, this is the reason why I added the "ptr" postfix to the names: I wanted to keep them different from the actual function names. We can now smooth out the icky struct syntax and get the desired names, by using some macros:

#define dll_add (functions.by_type.dll_add_ptr)
#define dll_subtract (functions.by_type.dll_subtract_ptr)
#define dll_do_stuff (functions.by_type.dll_do_stuff_ptr)

And voilà, you can now use the function names, with the correct type and parameters, as if they were statically linked to your project:

int result = dll_add(1, 1);

Disclaimer: Strictly speaking, conversions between different function pointers are not defined by the C standard and not safe. So formally, what I'm doing here is undefined behavior. However, in the Windows world, function pointers are always of the same size no matter their type and the conversions between them are predictable on any version of Windows I've used.

Also, there might in theory be padding inserted in the union/struct, which would cause everything to fail. However, pointers happen to be of the same size as the alignment requirement in Windows. A static_assert to ensure that the struct/union has no padding might be in order still.

This plagued me for over an hour.

If you're using the dataSrc option and column defs option, make sure they are in the correct locations. I had nested column defs in the ajax settings and lost way too much time figuring that out.

This is good:

This is not good:

Subtle difference, but real enough to cause hair loss.

git config user.name
git config user.email

I believe these are the commands you are looking for.

You can use the cherry-pick to get the particular bug fix commit(s)

$ git checkout branch
$ git cherry-pick bugfix

you can use requestAnimationFrame() function like in the below,

function unlimited () {
    requestAnimationFrame(unlimited);
    console.log("arian")
}

unlimited();

See http://wiki.apache.org/httpd/DistrosDefaultLayout for discussion of where you might find Apache httpd configuration files on various platforms, since this can vary from release to release and platform to platform. The most common answer, however, is either /etc/apache/conf or /etc/httpd/conf

Generically, you can determine the answer by running the command:

httpd -V

(That's a capital V). Or, on systems where httpd is renamed, perhaps apache2ctl -V

This will return various details about how httpd is built and configured, including the default location of the main configuration file.

One of the lines of output should look like:

-D SERVER_CONFIG_FILE="conf/httpd.conf"

which, combined with the line:

-D HTTPD_ROOT="/etc/httpd"

will give you a full path to the default location of the configuration file

when iserting into t-sql

this fails:

select CONVERT(datetime,'2019-09-13 09:04:35.823312',21)

this works:

select CONVERT(datetime,'2019-09-13 09:04:35.823',21)

easy way:

regexp = re.compile(r'\.(\d{6})')
def to_splunk_iso(dt):
    """Converts the datetime object to Splunk isoformat string."""
    # 6-digits string.
    microseconds = regexp.search(dt).group(1)
    return regexp.sub('.%d' % round(float(microseconds) / 1000), dt)

C++ is mostly a superset of C. You can continue doing what you were doing.

That said, in C++, what you ought to do is to define a proper Matrix class that manages its own memory. It could, for example be backed by an internal std::vector, and you could override operator[] or operator() to index into the vector appropriately (for example, see: How do I create a subscript operator for a Matrix class? from the C++ FAQ).

To get you started:

class Matrix
{
public:
    Matrix(size_t rows, size_t cols);
    double& operator()(size_t i, size_t j);
    double operator()(size_t i, size_t j) const;

private:
    size_t mRows;
    size_t mCols;
    std::vector<double> mData;
};

Matrix::Matrix(size_t rows, size_t cols)
: mRows(rows),
  mCols(cols),
  mData(rows * cols)
{
}

double& Matrix::operator()(size_t i, size_t j)
{
    return mData[i * mCols + j];
}

double Matrix::operator()(size_t i, size_t j) const
{
    return mData[i * mCols + j];
}

(Note that the above doesn't do any bounds-checking, and I leave it as an exercise to template it so that it works for things other than double.)

TESTED Hope this helps someone.

My simple approach (Think tags as your original code)

<html>
<div ng-click="myfuncion"> 
<my-dir callfunction="myfunction">
</html>

<directive "my-dir">
callfunction:"=callfunction"
link : function(scope,element,attr) {
scope.callfunction = function() {
 /// your code
}
}
</directive>

Here is a shorter version of the function presented above:

function getWidth() {
    if (self.innerWidth) {
       return self.innerWidth;
    }
    else if (document.documentElement && document.documentElement.clientHeight){
        return document.documentElement.clientWidth;
    }
    else if (document.body) {
        return document.body.clientWidth;
    }
    return 0;
}

I guess your code uses somewhere in the second case a singular matrix (i.e. not invertible), and the solve function needs to invert it. This has nothing to do with the size but with the fact that some of your vectors are (probably) colinear.

1)Yes it is, when there is style then it is styling your code(css).2) is belong to html it is like a container that keep your css.

A simple comparison against string works:

<c:when test="${someModel.status == 'OLD'}">

I personally prefer using the following code if it is for a single link. Otherwise it's probably best if you create a function with similar code.

onclick="this.target='_blank';"

I started using that to bypass the W3C's XHTML strict test.

I finally created a workaround around this frustrating issue. I'm not completely happy with the workaround, but it's better than nothing.

Basically, after you paste the source code and unambigous imports are fixed, just press F2 to highlight the next compiler error. If the current error is an import-missing error, press Alt+Enter, then Enter to select the Import option, then pick the correct import. Then, press F2 again.

 LayoutInflater factory = LayoutInflater.from(this);
final View textEntryView = factory.inflate(R.layout.text_entry, null);
//text_entry is an Layout XML file containing two text field to display in alert dialog
final EditText input1 = (EditText) textEntryView.findViewById(R.id.EditText1);
final EditText input2 = (EditText) textEntryView.findViewById(R.id.EditText2);             
input1.setText("DefaultValue", TextView.BufferType.EDITABLE);
input2.setText("DefaultValue", TextView.BufferType.EDITABLE);
final AlertDialog.Builder alert = new AlertDialog.Builder(this);

alert.setIcon(R.drawable.icon)
     .setTitle("Enter the Text:")
     .setView(textEntryView)
     .setPositiveButton("Save", 
         new DialogInterface.OnClickListener() {
             public void onClick(DialogInterface dialog, int whichButton) {
                    Log.i("AlertDialog","TextEntry 1 Entered "+input1.getText().toString());
                    Log.i("AlertDialog","TextEntry 2 Entered "+input2.getText().toString());
                    /* User clicked OK so do some stuff */
             }
         })
     .setNegativeButton("Cancel",
         new DialogInterface.OnClickListener() {
             public void onClick(DialogInterface dialog,
                    int whichButton) {
             }
         });
alert.show();

I think your confusion lies with multiple inheritance, in which it is bad practise to do so and in Java this is also not possible. However, implementing multiple interfaces is allowed in Java and it is also safe.

Why don't you take a look to this answer

Including javascript files inside javascript files

In short you can load the script file with AJAX or put a script tag on the HTML to include it( before the script that uses the functions of the other script). The link I posted is a great answer and has multiple examples and explanations of both methods.

I added "\Anaconda3_64\" and "\Anaconda3_64\Scripts\" to the PATH variable. Then I can use conda from powershell or command prompt.

In my case, this error was due to incorrect paths used to specify intents in my preferences xml file after I renamed the project. For instance, where I had:

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
    <Preference
        android:key="pref_edit_recipe_key"
        android:title="Add/Edit Recipe">
        <intent
            android:action="android.intent.action.VIEW"
            android:targetPackage="com.ssimon.olddirectory"
            android:targetClass="com.ssimon.olddirectory.RecipeEditActivity"/>
    </Preference>
</PreferenceScreen> 

I needed the following instead:

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
    <Preference
        android:key="pref_edit_recipe_key"
        android:title="Add/Edit Recipe">
        <intent
            android:action="android.intent.action.VIEW"
            android:targetPackage="com.ssimon.newdirectory"
            android:targetClass="com.ssimon.newdirectory.RecipeEditActivity"/>
</Preference>

Correcting the path names fixed the problem.

Update:

Separate the event and property bindings:

<select [ngModel]="selectedItem" (ngModelChange)="onChange($event)">

onChange(newValue) {
    console.log(newValue);
    this.selectedItem = newValue;  // don't forget to update the model here
    // ... do other stuff here ...
}

You could also use

<select [(ngModel)]="selectedItem" (ngModelChange)="onChange($event)">

and then you wouldn't have to update the model in the event handler, but I believe this causes two events to fire, so it is probably less efficient.

Old answer, before they fixed a bug in beta.1:

Create a local template variable and attach a (change) event:

<select [(ngModel)]="selectedItem" #item (change)="onChange(item.value)">

Much belated answer:

I've been wrestling with this on and off since I first started working in ASP. Here's the best I've come up with:

Concept: I create a custom control that has a tag. Then in the button I put an onclick event that sets document.location to the desired value with JavaScript.

I called the control ButtonLink, so that I could easily get if confused with LinkButton.

Advantages of this scheme: It looks like a control. You write a single tag for it, <ButtonLink id="mybutton" navigateurl="blahblah"/>

The resulting button is a "real" HTML button and so looks just like a real button. You don't have to try to simulate the look of a button with CSS and then struggle with different looks on different browsers.

While the abilities are limited, you can easily extend it by adding more properties. It's likely that most properties would just have to "pass thru" to the underlying button, like I did for text, enabled and cssclass.

If anybody's got a simpler, cleaner or otherwise better solution, I'd be happy to hear it. This is a pain, but it works.

Here's a complete Java 7 program:

class GETHTTPResource {
  public static void main(String[] args) throws Exception {
    try (java.util.Scanner s = new java.util.Scanner(new java.net.URL("http://tools.ietf.org/rfc/rfc768.txt").openStream())) {
      System.out.println(s.useDelimiter("\\A").next());
    }
  }
}

The new try-with-resources will auto-close the Scanner, which will auto-close the InputStream.

If you don't need full debugging support, you can now view JavaScript console logs directly within Chrome for iOS at chrome://inspect.

Finally solved it ;). Got a strong hint here (Gandalfs answer touched a bit on it as well). The missing links was (mostly) the first of the parameters below, and to some extent that I overlooked the difference between keystores and truststores.

The self-signed server certificate must be imported into a truststore:

keytool -import -alias gridserver -file gridserver.crt -storepass $PASS -keystore gridserver.keystore

These properties need to be set (either on the commandline, or in code):

-Djavax.net.ssl.keyStoreType=pkcs12
-Djavax.net.ssl.trustStoreType=jks
-Djavax.net.ssl.keyStore=clientcertificate.p12
-Djavax.net.ssl.trustStore=gridserver.keystore
-Djavax.net.debug=ssl # very verbose debug
-Djavax.net.ssl.keyStorePassword=$PASS
-Djavax.net.ssl.trustStorePassword=$PASS

Working example code:

SSLSocketFactory sslsocketfactory = (SSLSocketFactory) SSLSocketFactory.getDefault();
URL url = new URL("https://gridserver:3049/cgi-bin/ls.py");
HttpsURLConnection conn = (HttpsURLConnection)url.openConnection();
conn.setSSLSocketFactory(sslsocketfactory);
InputStream inputstream = conn.getInputStream();
InputStreamReader inputstreamreader = new InputStreamReader(inputstream);
BufferedReader bufferedreader = new BufferedReader(inputstreamreader);

String string = null;
while ((string = bufferedreader.readLine()) != null) {
    System.out.println("Received " + string);
}

use inline-block instead of inline. Read more information here about the difference between inline and inline-block.

.inline { 
display: inline-block; 
border: 1px solid red; 
margin:10px;
}

Uninstall(delete) this: jre, jdk, eclipse. Download 32 bit(x86) version of this programs:jre, jdk, eclipse. And install it.

In WAMP the files are served by the Apache component (the A in WAMP).

In Apache, by default the files served are located in the subdirectory htdocs of the installation directory. But this can be changed, and is actually changed when WAMP installs Apache.

The location from where the files are served is named the DocumentRoot, and is defined using a variable in Apache configuration file. The default value is the subdirectory htdocs relative to what is named the ServerRoot directory.

By default the ServerRoot is the installation directory of Apache. However this can also be redefined into the configuration file, or using the -d option of the command httpd which is used to launch Apache. The value in the configuration file overrides the -d option.

The configuration file is by default conf/httpd.conf relative to ServerRoot. But this can be changed using the -f option of command httpd.

When WAMP installs itself, it modify the default configuration file with DocumentRoot c:/wamp/www/. The files to be served need to be located here and not in the htdocs default directory.

You may change this location set by WAMP, either by modifying DocumentRoot in the default configuration file, or by using one of the two command line options -f or -d which point explicitly or implicity to a new configuration file which may hold a different value for DocumentRoot (in that case the new file needs to contain this definition, but also the rest of the configuration found in the default configuration file).

Sometimes autoplay is needed. Someone once pointed out that the famous Les Paul Google Doodle (2011) required autoplay, even though the sound didn't play until you moused over the guitar strings. If it's done with class and great design it can be beautiful (especially movie websites with immersive design)

Use this for datetimepicker, it works fine

$('#Date').data("DateTimePicker").hide();

For Mac User's It's Best use the manual installation:

To minimize the chance of permissions errors, you can configure npm to use a different directory. In this example, it will be a hidden directory on your home folder.

1. Back-up your computer before you start.

2. Make a directory for global installations:

   mkdir ~/.npm-global

3. Configure npm to use the new directory path:

   npm config set prefix '~/.npm-global'

4. Open or create a ~/.profile file and add this line:

   export PATH=~/.npm-global/bin:$PATH

5. Back on the command line, update your system variables:

   source ~/.profile

6. Test: Download a package globally without using sudo.

   npm install -g jshint

Instead of steps 2-4, you can use the corresponding ENV variable (e.g. if you don't want to modify ~/.profile):

NPM_CONFIG_PREFIX=~/.npm-global

Use the index to get desired node if xpath is complicated or more than one node present with same xpath.

Ex :

(//bookstore[@location = 'US'])[index]

You can give the number which node you want.

The easiest way to write console output to text file is

//create a file first    
    PrintWriter outputfile = new PrintWriter(filename);
//replace your System.out.print("your output");
    outputfile.print("your output");
    outputfile.close(); 

Try GraphIT from TechNewLogic, you can find it on CodePlex here: http://graphit.codeplex.com

Full Disclosure: I am the developer of GraphIT and owner of the developing company.

$blue_keys = array_search("blue", array_keys($a));

http://php.net/manual/en/function.array-keys.php

Using only "native" Windows utilities, try the following, where "516" is the process ID that you want the image name for:

for /f "delims=," %a in ( 'tasklist /fi "PID eq 516" /nh /fo:csv' ) do ( echo %~a )
for /f %a in ( 'tasklist /fi "PID eq 516" ^| findstr "516"' ) do ( echo %a )

Or you could use wmic (the Windows Management Instrumentation Command-line tool) and get the full path to the executable:

wmic process where processId=516 get name
wmic process where processId=516 get ExecutablePath

Or you could download Microsoft PsTools, or specifically download just the pslist utility, and use PsList:

for /f %a in ( 'pslist 516 ^| findstr "516"' ) do ( echo %a )

you are calling the push() on an array element (int), where push() should be called on the array, also handling/filling the array this way makes no sense you can do it like this

for (var i = 0; i < rows - 1; i++)
{
  for (var j = c; j < cols; j++)
  {
    myArray[i].push(0);
  }
}


for (var i = r; i < rows - 1; i++)
{

  for (var j = 0; j < cols; j++)
  {
      col.push(0);
  }
}

you can also combine the two loops using an if condition, if row < r, else if row >= r

I also want to do the same thing: migrate a db from a standalone redis instance to a another redis instances(redis sentinel).

Because the data is not critical(session data), i will give https://github.com/yaauie/redis-copy a try.

Steps to create Hash Key. 
1: Download openssl from Openssl for Windows . I downloaded the Win64 version 
2:Unzip and copy all the files in the bin folder including openssl.exe(All file of bin folder) 
3:Goto to the folder where you installed JDK for me it’s C:\Program Files\Java\jdk1.8.0_05\bin 
4:Paste all the files you copied from Openssl’s bin folder to the Jdk folder. 

then go C:\Program Files\Java\jdk1.8.0_05\bin and press shift key and right click and open cmd

C:\Program Files\Java\jdk1.8.0_05\bin>//cmd path 

that is for Sha1 past this
keytool -exportcert -alias androiddebugkey -keystore "C:\User\ABC\.android.keystore" | openssl sha1 -binary | openssl base64
//and ABC is system name put own system name

Update:

I'm not sure when or if the license changed for the iText# library, but it is licensed under AGPL which means it must be licensed if included with a closed-source product. The question does not (currently) require free or open-source libraries. One should always investigate the license type of any library used in a project.

I have used iText# with success in .NET C# 3.5; it is a port of the open source Java library for PDF generation and it's free.

There is a NuGet package available for iTextSharp version 5 and the official developer documentation, as well as C# examples, can be found at itextpdf.com

document.getElementsByClassName returns a node list. So you'll have to iterate over the list and bind the event to individual elements. Like this...

var buttons = document.getElementsByClassName("navButton");

for(var i = 0; i < buttons.length; ++i){
    buttons[i].onmouseover = function() {
        this.setAttribute("class", "active");
        this.setAttribute("src", "images/arrows/top_o.png");
    }
}

You have to create the .ssh folder yourself for saving ssh keys.

By the way, I used this path style: C:/Users/you/.ssh/id_rsa

The typical pattern is to check out the root project folder (=the one containing a file called ".project") from SVN using eclipse's svn integration (SVN repository exploring perspective). The project is then recognized automatically.

If you're doing this through cygwin, you may need to use cygpath:

$ git config difftool.bc3.cmd "git-diff-bcomp-wrapper.sh \$LOCAL \$REMOTE"
$ cat git-diff-bcomp-wrapper.sh
#!/bin/sh
"c:/Program Files (x86)/Beyond Compare 3/BComp.exe" `cygpath -w $1` `cygpath -w $2`

the first time when you are returning your form make sure you pass the model attribute the form requires which can be done by adding the below code

@RequestMapping(value = "/login", method = RequestMethod.GET)
public String login(Login login)
    return "test";
}

By default the model attribute name is taken as Bean class's name with first lowercase letter

By doing this the form which expects a backing object naming "login" will be made available to it

after the form is submitted you can do the validation by passing your bean object and bindingresult as the method parameters as shown below

@RequestMapping(value = "/login", method = RequestMethod.POST)
public String login(    @ModelAttribute("login") Login login,
                        BindingResult result) 

You can find the number of members in a Javascript array by using its length property:

var number = $scope.names.length;

^{Docs - Array.prototype.length}

I found that I needed to group by the month and year so neither of the above worked for me. Instead I used date_format

SELECT date
FROM blog 
GROUP BY DATE_FORMAT(date, "%m-%y")
ORDER BY YEAR(date) DESC, MONTH(date) DESC 

Try these:

#dialog_style1 .ui-dialog-titlebar { display:none; }
#dialog_style2 .ui-dialog-titlebar { color:#aaa; }

The best recommendation I can give for you is to load the page in Firefox, open the dialog and inspect it with Firebug, then try different selectors in the console, and see what works. You may need to use some of the other descendant selectors.

SELECT documentid, 
       status, 
       datecreated 
FROM   documentstatuslogs dlogs 
WHERE  status = (SELECT status 
                 FROM   documentstatuslogs 
                 WHERE  documentid = dlogs.documentid 
                 ORDER  BY datecreated DESC 
                 LIMIT  1) 

You can be explicit about the joins:

SELECT Table1.Col1, Table1.Col2, Table1.Col3, Table2.Col4
FROM Table1 INNER JOIN
     Table2
      ON (Table1.Col1 = Table2.Col1 or Table1.Col1 is NULL and Table2.Col1 is NULL) AND
         (Table1.Col2 = Table2.Col2 or Table1.Col2 is NULL and Table2.Col2 is NULL)

In practice, I would be more likely to use coalesce() in the join condition:

SELECT Table1.Col1, Table1.Col2, Table1.Col3, Table2.Col4
FROM Table1 INNER JOIN
     Table2
     ON (coalesce(Table1.Col1, '') = coalesce(Table2.Col1, '')) AND
        (coalesce(Table1.Col2, '') = coalesce(Table2.Col2, ''))

Where '' would be a value not in either of the tables.

Just a word of caution. In most databases, using any of these constructs prevents the use of indexes.

If you know how many rows to expect, I would create a separate temporary table in your database of the expected structure, append into that, then check the count... Once you are good with that, then you can massage that data before appending it into your final production table.

Disadvantage of second approach is big repository with created loggers. This loggers do the same if root is defined and class loggers are not defined. Standard scenario on production system is using few loggers dedicated to group of class. Sorry for my English.

I encounter similar situation. I would like to have background of the last .item to be yellow in the elements that look like...

<div class="container">
  <div class="item">item 1</div>
  <div class="item">item 2</div>
  <div class="item">item 3</div>
  ...
  <div class="item">item x</div>
  <div class="other">I'm here for some reasons</div>
</div>

I use nth-last-child(2) to achieve it.

.item:nth-last-child(2) {
  background-color: yellow;
}

It strange to me because nth-last-child of item suppose to be the second of the last item but it works and I got the result as I expect. I found this helpful trick from CSS Trick

instanceof can only be used with reference types, not primitive types. isAssignableFrom() can be used with any class objects:

a instanceof int  // syntax error
3 instanceof Foo  // syntax error
int.class.isAssignableFrom(int.class)  // true

See http://java.sun.com/javase/6/docs/api/java/lang/Class.html#isAssignableFrom(java.lang.Class).

The set statement doesn't treat spaces the way you expect; your variable is really named Pathname[space] and is equal to [space]C:\Program Files.

Remove the spaces from both sides of the = sign, and put the value in double quotes:

set Pathname="C:\Program Files"

Also, if your command prompt is not open to C:\, then using cd alone can't change drives.

Use

cd /d %Pathname%

or

pushd %Pathname%

instead.

It's not possible to access camera of your development machine to be used as simulator camera. Camera functionality is not available in any iOS version and any Simulator. You will have to use device for testing camera purpose.

For npm

 npm install --save core-js@^3

for yarn

yarn add core-js@^3

You should write the pickled data with a lower protocol number in Python 3. Python 3 introduced a new protocol with the number 3 (and uses it as default), so switch back to a value of 2 which can be read by Python 2.

Check the protocolparameter in pickle.dump. Your resulting code will look like this.

pickle.dump(your_object, your_file, protocol=2)

There is no protocolparameter in pickle.load because pickle can determine the protocol from the file.

Try to split the characters into multiple chunks like the query below and try:

Insert into table (clob_column) values ( to_clob( 'chunk 1' ) || to_clob( 'chunk 2' ) );

It worked for me.

The text at the navigation bar is normally colored by using one of the two following css classes in the bootstrap.css file.

Firstly, in case of using a default navigation bar (the gray one), the .navbar-default class will be used and the text is colored as dark gray.

.navbar-default .navbar-text {
  color: #777;
}

The other is in case of using an inverse navigation bar (the black one), the text is colored as gray60.

.navbar-inverse .navbar-text {
  color: #999;
}

So, you can change its color as you wish. However, I would recommend you to use a separate css file to change it.

NOTE: you could also use the customizer provided by Twitter Bootstrap, in the Navbar section.

In curl request add time out 0 so its infinite time set like CURLOPT_TIMEOUT set 0

add:

.SubItems.Add("asdasdasd");

to the last line of your code so it will look like this in the end.

listView1.Items.Add("sdasdasdasd").SubItems.Add("asdasdasd");

this solved my issue, it was working fine with

var value = item[index].id;
$("#select2").val(value);

but not showing selected value, so

$("#select2").val(value).change();

works fine for me.

Have a look at the following example of the jQueryUI Autocomplete, as it is keeping a select around and I think that is what you are looking for. Hope this helps.

I aimed at creating a simple non-mutating solution in pure ES6. Peculiarities in javascript make it necessary to fill the empty array before mapping :-(

function chunk(a, l) { 
    return new Array(Math.ceil(a.length / l)).fill(0)
        .map((_, n) => a.slice(n*l, n*l + l)); 
}

This version with recursion seem simpler and more compelling:

function chunk(a, l) { 
    if (a.length == 0) return []; 
    else return [a.slice(0, l)].concat(chunk(a.slice(l), l)); 
}

The ridiculously weak array functions of ES6 makes for good puzzles :-)

The OVER clause specifies the partitioning, ordering and window "over which" the analytic function operates.

Example #1: calculate a moving average

AVG(amt) OVER (ORDER BY date ROWS BETWEEN 1 PRECEDING AND 1 FOLLOWING)

date   amt   avg_amt
=====  ====  =======
1-Jan  10.0  10.5
2-Jan  11.0  17.0
3-Jan  30.0  17.0
4-Jan  10.0  18.0
5-Jan  14.0  12.0

It operates over a moving window (3 rows wide) over the rows, ordered by date.

Example #2: calculate a running balance

SUM(amt) OVER (ORDER BY date ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW)

date   amt   sum_amt
=====  ====  =======
1-Jan  10.0  10.0
2-Jan  11.0  21.0
3-Jan  30.0  51.0
4-Jan  10.0  61.0
5-Jan  14.0  75.0

It operates over a window that includes the current row and all prior rows.

Note: for an aggregate with an OVER clause specifying a sort ORDER, the default window is UNBOUNDED PRECEDING to CURRENT ROW, so the above expression may be simplified to, with the same result:

SUM(amt) OVER (ORDER BY date)

Example #3: calculate the maximum within each group

MAX(amt) OVER (PARTITION BY dept)

dept  amt   max_amt
====  ====  =======
ACCT   5.0   7.0
ACCT   7.0   7.0
ACCT   6.0   7.0
MRKT  10.0  11.0
MRKT  11.0  11.0
SLES   2.0   2.0

It operates over a window that includes all rows for a particular dept.

Bootstrap has it's own centering class named text-center.

<div class="span7 text-center"></div>

Press A to enter edit mode starting at the end of the line.

function func(a, b)
{
  if (typeof a == 'undefined')
    a = 10;
  if (typeof b == 'undefined')
    b = 20;
  // do what you want ... for example
  alert(a + ',' + b);
}

in shorthand

function func(a, b)
{
  a = (typeof a == 'undefined')?10:a;
  b = (typeof b == 'undefined')?20:b;

  // do what you want ... for example
  alert(a + ',' + b);
}

Facebook uses MQTT instead of HTTP. Push is better than polling. Through HTTP we need to poll the server continuously but via MQTT server pushes the message to clients.

If you are using eclipse, you should modify the context.xml, from the server project created in your eclipse package explorer. When using tomcat in eclipse it is the only one valid, the others are ignored or overwriten

I would strongly suggest using an npm package implementing correctly the base64 specification.

The best one I know is rfc4648

The problem is that btoa and atob use binary strings instead of Uint8Array and trying to convert to and from it is cumbersome. Also there is a lot of bad packages in npm for that. I lose a lot of time before finding that one.

The creators of that specific package did a simple thing: they took the specification of Base64 (which is here by the way) and implemented it correctly from the beginning to the end. (Including other formats in the specification that are also useful like Base64-url, Base32, etc ...) That doesn't seem a lot but apparently that was too much to ask to the bunch of other libraries.

So yeah, I know I'm doing a bit of proselytism but if you want to avoid losing your time too just use rfc4648.

Static members are universal members. They can be accessed from anywhere.

The important difference between constructors and methods is that constructors initialize objects that are being created with the new operator, while methods perform operations on objects that already exist.

Constructors can't be called directly; they are called implicitly when the new keyword creates an object. Methods can be called directly on an object that has already been created with new.

The definitions of constructors and methods look similar in code. They can take parameters, they can have modifiers (e.g. public), and they have method bodies in braces.

Constructors must be named with the same name as the class name. They can't return anything, even void (the object itself is the implicit return).

Methods must be declared to return something, although it can be void.

This is a warning from distutils, and is a sign that you do not have setuptools installed. Installing it from http://pypi.python.org/pypi/setuptools will remove the warning.

I'd like to write explicitly two methods which allow accomplishing this in pure JavaScript:

document.getElementsByClassName('realClasssName').length

Note 1: Argument of this method needs a string with the real class name, without the dot at the begin of this string.

document.querySelectorAll('.realClasssName').length

Note 2: Argument of this method needs a string with the real class name but with the dot at the begin of this string.

Note 3: This method works also with any other CSS selectors, not only with class selector. So it's more universal.

I also write one method, but using two name conventions to solve this problem using jQuery:

jQuery('.realClasssName').length

or

$('.realClasssName').length

Note 4: Here we also have to remember about the dot, before the class name, and we can also use other CSS selectors.

Setting a min-width on child elements will also create a breakpoint. For example breaking every 3 elements,

flex-grow: 1;
min-width: 33%; 

If there are 4 elements, this will have the 4th element wrap taking the full 100%. If there are 5 elements, the 4th and 5th elements will wrap and take each 50%.

Make sure to have parent element with,

flex-wrap: wrap

Add the same attribute as you have on the Close button:

data-dismiss="modal"

e.g.

<button type="submit" class="btn btn-success" data-dismiss="modal"><i class="glyphicon glyphicon-ok"></i> Save</button>

You can also use jQuery if you wish:

$('#frmStudent').submit(function() {

    // submission stuff

    $('#StudentModal').modal('hide');
    return false;
});

We can code like following also, I have used blur event here.

$("#proprice, #proqty").blur(function(){
      var price=$("#proprice").val();
      var qty=$("#proqty").val();
      if(price != '' || qty != '')
      {
          $("#totalprice").val(qty*price);
      }
  });

I had the same problem and here was my way to solve it:

First, You must know your IP address. On my Windows PC, in the cmd windows i run ipconfig and select my IP V4 address. In my case 192.168.0.13

Second as mention above: runserver 192.168.0.13:8000

It worked for me. The error i did to get the message was the use of the gateway address not my PC address.

You may need to check who the actual owner of the stored procedure is. If it is a specific different user then that could be why you can't access it.

The code you posted is wrong.

You shouldn't make multiple calls to DateTime.Today. If you happen to run that code just as the date changes you could get completely wrong results. For example if you ran it on December 31st 2011 you might get "2011-1-1".

Use a single call to DateTime.Today then use ToString with an appropriate format string to format the date as you desire.

string result = DateTime.Today.AddDays(-1).ToString("yyyy-MM-dd");

The problem could occur when $templateCacheProvider is trying to resolve a template in the templateCache or through your project directory that does not exist

Example:

templateUrl: 'views/wrongPathToTemplate'

Should be:

templateUrl: 'views/home.html'

You need to use the change directory command 'cd' to change directory

cd C:\Users\MyName\Desktop

you can use cd \d to change the drive as well.

I've also had this error when trying to pull the changes into a branch which is not created from the upstream branch from which I'm trying to pull.

Eg - This creates a new branch matching night-version of upstream

git checkout upstream/night-version -b testnightversion

This creates a branch testmaster in local which matches the master branch of upstream.

git checkout upstream/master -b testmaster 

Now if I try to pull the changes of night-version into testmaster branch leads to this error.

git pull upstream night-version //while I'm in `master` cloned branch

I managed to solve this by navigating to proper branch and pull the changes.

git checkout testnightversion
git pull upstream night-version // works fine.

The WhiteSpace CHAR can be referenced using ASCII Codes here. And Character# 32 represents a white space, Therefore:

char space = (char)32;

For example, you can use this approach to produce desired number of white spaces anywhere you want:

int _length = {desired number of white spaces}
string.Empty.PadRight(_length, (char)32));

I had same problem, I solved this problem by following way.

Right click on page, select Property. in build action select Content.

Hope that this solution may help you.

Try setting an implicit wait of maybe 10 seconds.

gmail.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

Or set an explicit wait. An explicit waits is code you define to wait for a certain condition to occur before proceeding further in the code. In your case, it is the visibility of the password input field. (Thanks to ainlolcat's comment)

WebDriver gmail= new ChromeDriver();
gmail.get("https://www.gmail.co.in"); 
gmail.findElement(By.id("Email")).sendKeys("abcd");
gmail.findElement(By.id("next")).click();
WebDriverWait wait = new WebDriverWait(gmail, 10);
WebElement element = wait.until(
ExpectedConditions.visibilityOfElementLocated(By.id("Passwd")));
gmail.findElement(By.id("Passwd")).sendKeys("xyz");

Explanation: The reason selenium can't find the element is because the id of the password input field is initially Passwd-hidden. After you click on the "Next" button, Google first verifies the email address entered and then shows the password input field (by changing the id from Passwd-hidden to Passwd). So, when the password field is still hidden (i.e. Google is still verifying the email id), your webdriver starts searching for the password input field with id Passwd which is still hidden. And hence, an exception is thrown.

int x = 0xFF;   //your number - 11111111

How do I for example read a 3 bit integer value starting at the second bit

int y = x & ( 0x7 << 2 ) // 0x7 is 111
                         // and you shift it 2 to the left
