Since there is no break in Scala yet, you could try to solve this problem with using a return-statement. Therefore you need to put your inner loop into a function, otherwise the return would skip the whole loop.

Scala 2.8 however includes a way to break

http://www.scala-lang.org/api/rc/scala/util/control/Breaks.html

Look here:

http://tratt.net/laurie/tech_articles/articles/tail_call_optimization

As you probably know, recursive function calls can wreak havoc on a stack; it is easy to quickly run out of stack space. Tail call optimization is way by which you can create a recursive style algorithm that uses constant stack space, therefore it does not grow and grow and you get stack errors.

here is a Perl 5 version of the tailrecsum function mentioned earlier.

sub tail_rec_sum($;$){
  my( $x,$running_total ) = (@_,0);

  return $running_total unless $x;

  @_ = ($x-1,$running_total+$x);
  goto &tail_rec_sum; # throw away current stack frame
}

You would want to use a set instead of a list.

you can use valign="top" on the td tag it is working perfectly for me.

Taken from the css3mediaqueries.js project page.

Note: Doesn't work on @import'ed stylesheets (which you shouldn't use anyway for performance reasons). Also won't listen to the media attribute of the <link> and <style> elements.

You can tag your DOM element using #someTag, then get it with @ViewChild('someTag').

See complete example:

import {AfterViewInit, Component, ElementRef, ViewChild} from '@angular/core';

@Component({
    selector: 'app',
    template: `
        <div #myDiv>Some text</div>
    `,
})
export class AppComponent implements AfterViewInit {
    @ViewChild('myDiv') myDiv: ElementRef;

    ngAfterViewInit() {
        console.log(this.myDiv.nativeElement.innerHTML);
    }
}

console.log will print Some text.

Though $toInt is really useful, it was added on mongoDB 4.0, I've run into this same situation in a database running 3.2 which upgrading to use $toInt was not an option due to some other application incompatibilities, so i had to come up with something else, and actually was surprisingly simple.

If you $project and $add zero to your string, it will turn into a number

{
  $project : {
  'convertedField' : { $add : ["$stringField",0] },
  //more fields here...
  }
}

str.split('Yes').join('No'); 

This will replace all the occurrences of that specific string from original string.

Your Application.java class should extend the SpringBootServletInitializer class ex:

public class Application extends SpringBootServletInitializer {}

This is defined in the ECMAScript Optional Chaining specification, so we should probably refer to optional chaining when we discuss this. Likely implementation:

const result = a?.b?.c;

The long and short of this one is that the TypeScript team are waiting for the ECMAScript specification to get tightened up, so their implementation can be non-breaking in the future. If they implemented something now, it would end up needing major changes if ECMAScript redefine their specification.

See Optional Chaining Specification

Where something is never going to be standard JavaScript, the TypeScript team can implement as they see fit, but for future ECMAScript additions, they want to preserve semantics even if they give early access, as they have for so many other features.

Short Cuts

So all of JavaScripts funky operators are available, including the type conversions such as...

var n: number = +myString; // convert to number
var b: bool = !!myString; // convert to bool

Manual Solution

But back to the question. I have an obtuse example of how you can do a similar thing in JavaScript (and therefore TypeScript) although I'm definitely not suggesting it is a graceful as the feature you are really after.

(foo||{}).bar;

So if foo is undefined the result is undefined and if foo is defined and has a property named bar that has a value, the result is that value.

I put an example on JSFiddle.

This looks quite sketchy for longer examples.

var postCode = ((person||{}).address||{}).postcode;

Chain Function

If you are desperate for a shorter version while the specification is still up in the air, I use this method in some cases. It evaluates the expression and returns a default if the chain can't be satisfied or ends up null/undefined (note the != is important here, we don't want to use !== as we want a bit of positive juggling here).

function chain<T>(exp: () => T, d: T) {
    try {
        let val = exp();
        if (val != null) {
            return val;
        }
    } catch { }
    return d;
}

let obj1: { a?: { b?: string }} = {
    a: {
        b: 'c'
    }
};

// 'c'
console.log(chain(() => obj1.a.b, 'Nothing'));

obj1 = {
    a: {}
};

// 'Nothing'
console.log(chain(() => obj1.a.b, 'Nothing'));

obj1 = {};

// 'Nothing'
console.log(chain(() => obj1.a.b, 'Nothing'));

obj1 = null;

// 'Nothing'
console.log(chain(() => obj1.a.b, 'Nothing'));

Change column position:

ALTER TABLE Employees 
   CHANGE empName empName VARCHAR(50) NOT NULL AFTER department;

If you need to move it to the first position you have to use term FIRST at the end of ALTER TABLE CHANGE [COLUMN] query:

ALTER TABLE UserOrder 
   CHANGE order_id order_id INT(11) NOT NULL FIRST;

You can install it by first extracting all the files from the ISO and then overwriting those files with the files from the ZIP. Then you can run the batch file as administrator to do the installation. Most of the packages install on windows 7, but I haven't tested yet how well they work.

It's declared inside a closure, which means it can only be accessed there. If you want a variable accessible globally, you can remove the var:

$(function(){
    value = "10";
});
value; // "10"

This is equivalent to writing window.value = "10";.

Here's a good blog post that's just been posted by Fabrice (author of LINQ in Action) which covers the material in the question that I asked. I'm putting it here for reference as readers of the question will find this useful.

Converting LINQ queries from query syntax to method/operator syntax

AFAIK there is no property for that in the specs, but here is a trick I’ve been using: set the container element ( the one with display:flex ) to justify-content:space-around Then add an extra element between the first and second item and set it to flex-grow:10 (or some other value that works with your setup)

Edit: if the items are tightly aligned it's a good idea to add flex-shrink: 10; to the extra element as well, so the layout will be properly responsive on smaller devices.

Another way based on amadan:

    SELECT * FROM [Purchasing].[Vendor] WHERE  

      ( (@url IS null OR @url = '' OR @url = 'ALL') and   PurchasingWebServiceURL LIKE '%')
    or

       ( @url = 'blank' and  PurchasingWebServiceURL = '')
    or
        (@url = 'fail' and  PurchasingWebServiceURL NOT LIKE '%treyresearch%')
    or( (@url not in ('fail','blank','','ALL') and @url is not null and 
          PurchasingWebServiceUrl Like '%'+@ur+'%') 
END

You can't have a link to SCSS File in your HTML page.You have to compile it down to CSS First. No there are lots of video tutorials you might want to check out. Lynda provides great video tutorials on SASS. there are also free screencasts you can google...

For official documentation visit this site http://sass-lang.com/documentation/file.SASS_REFERENCE.html And why have you chosen notepad to write Sass?? you can easily download some free text editors for better code handling.

This can be useful to see the progress of long insert queries, make any rough estimates (like COUNT(*) or rough SUM(*)) etc.

In other words, the results the dirty read queries return are fine as long as you treat them as estimates and don't make any critical decisions based upon them.

The same way you do in C:

short big = 0xdead;
short little = (((big & 0xff)<<8) | ((big & 0xff00)>>8));

You could also declare a vector of unsigned chars, memcpy the input value into it, reverse the bytes into another vector and memcpy the bytes out, but that'll take orders of magnitude longer than bit-twiddling, especially with 64-bit values.

I came across this post looking for a "shaking" implementation. millenomi's answer worked well for me, although i was looking for something that required a bit more "shaking action" to trigger. I've replaced to Boolean value with an int shakeCount. I also reimplemented the L0AccelerationIsShaking() method in Objective-C. You can tweak the ammount of shaking required by tweaking the ammount added to shakeCount. I'm not sure i've found the optimal values yet, but it seems to be working well so far. Hope this helps someone:

- (void)accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration {
    if (self.lastAcceleration) {
        if ([self AccelerationIsShakingLast:self.lastAcceleration current:acceleration threshold:0.7] && shakeCount >= 9) {
            //Shaking here, DO stuff.
            shakeCount = 0;
        } else if ([self AccelerationIsShakingLast:self.lastAcceleration current:acceleration threshold:0.7]) {
            shakeCount = shakeCount + 5;
        }else if (![self AccelerationIsShakingLast:self.lastAcceleration current:acceleration threshold:0.2]) {
            if (shakeCount > 0) {
                shakeCount--;
            }
        }
    }
    self.lastAcceleration = acceleration;
}

- (BOOL) AccelerationIsShakingLast:(UIAcceleration *)last current:(UIAcceleration *)current threshold:(double)threshold {
    double
    deltaX = fabs(last.x - current.x),
    deltaY = fabs(last.y - current.y),
    deltaZ = fabs(last.z - current.z);

    return
    (deltaX > threshold && deltaY > threshold) ||
    (deltaX > threshold && deltaZ > threshold) ||
    (deltaY > threshold && deltaZ > threshold);
}

PS: I've set the update interval to 1/15th of a second.

[[UIAccelerometer sharedAccelerometer] setUpdateInterval:(1.0 / 15)];

If you are trying to find the current directory of the file you are currently in:

OS agnostic way:

dirname, filename = os.path.split(os.path.abspath(__file__))

To hide keyboard, use this one:

getActivity().getWindow().setSoftInputMode(
    WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

and to show keyboard:

getActivity().getWindow().setSoftInputMode(
    WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);

Why not use the built in events?

$('#checkbox').click(function(e){
    if(e.target.checked) {
     // code to run if checked
        console.log('Checked');

     } else {

     //code to run if unchecked
        console.log('Unchecked');
     }
});

Doing some sort of ser/deser or encode/decode trick seems ugly and requires you to remember what exactly you did when you are trying to use the constant. I think the class private static variable with accessor is a decent solution, but I'll do you one better. Just have a public static getter method that returns the definition of the constant array. This requires a minimum of extra code and the array definition cannot be accidentally modified.

class UserRoles {
    public static function getDefaultRoles() {
        return array('guy', 'development team');
    }
}

initMyRoles( UserRoles::getDefaultRoles() );

If you want to really make it look like a defined constant you could give it an all caps name, but then it would be confusing to remember to add the '()' parentheses after the name.

class UserRoles {
    public static function DEFAULT_ROLES() { return array('guy', 'development team'); }
}

//but, then the extra () looks weird...
initMyRoles( UserRoles::DEFAULT_ROLES() );

I suppose you could make the method global to be closer to the define() functionality you were asking for, but you really should scope the constant name anyhow and avoid globals.

I believe you want <= 90

lower(a) 
int a; 
{
    if ((a >= 65) && (a <= 90))
        a = a + 32; 
    return a;  
}

Although tolower would probably just save you the hassle unless you wanted to do this yourself. http://www.cplusplus.com/reference/cctype/tolower/

The following codes are my Powershell codes to determinate if some cpp or h or ml files are encodeding with ISO-8859-1(Latin-1) or UTF-8 without BOM, if neither then suppose it to be GB18030. I am a Chinese working in France and MSVC saves as Latin-1 on french computer and saves as GB on Chinese computer so this helps me avoid encoding problem when do source file exchanges between my system and my colleagues.

The way is simple, if all characters are between x00-x7E, ASCII, UTF-8 and Latin-1 are all the same, but if I read a non ASCII file by UTF-8, we will find the special character ? show up, so try to read with Latin-1. In Latin-1, between \x7F and \xAF is empty, while GB uses full between x00-xFF so if I got any between the two, it's not Latin-1

The code is written in PowerShell, but uses .net so it's easy to be translated into C# or F#

$Utf8NoBomEncoding = New-Object System.Text.UTF8Encoding($False)
foreach($i in Get-ChildItem .\ -Recurse -include *.cpp,*.h, *.ml) {
    $openUTF = New-Object System.IO.StreamReader -ArgumentList ($i, [Text.Encoding]::UTF8)
    $contentUTF = $openUTF.ReadToEnd()
    [regex]$regex = '?'
    $c=$regex.Matches($contentUTF).count
    $openUTF.Close()
    if ($c -ne 0) {
        $openLatin1 = New-Object System.IO.StreamReader -ArgumentList ($i, [Text.Encoding]::GetEncoding('ISO-8859-1'))
        $contentLatin1 = $openLatin1.ReadToEnd()
        $openLatin1.Close()
        [regex]$regex = '[\x7F-\xAF]'
        $c=$regex.Matches($contentLatin1).count
        if ($c -eq 0) {
            [System.IO.File]::WriteAllLines($i, $contentLatin1, $Utf8NoBomEncoding)
            $i.FullName
        } 
        else {
            $openGB = New-Object System.IO.StreamReader -ArgumentList ($i, [Text.Encoding]::GetEncoding('GB18030'))
            $contentGB = $openGB.ReadToEnd()
            $openGB.Close()
            [System.IO.File]::WriteAllLines($i, $contentGB, $Utf8NoBomEncoding)
            $i.FullName
        }
    }
}
Write-Host -NoNewLine 'Press any key to continue...';
$null = $Host.UI.RawUI.ReadKey('NoEcho,IncludeKeyDown');

no need to wrap it in a jquery object

So, far I have been exiting and reentering the Interpreter because re importing the file again is not working for me.

Yes, just saying import again gives you the existing copy of the module from sys.modules.

You can say reload(module) to update sys.modules and get a new copy of that single module, but if any other modules have a reference to the original module or any object from the original module, they will keep their old references and Very Confusing Things will happen.

So if you've got a module a, which depends on module b, and b changes, you have to ‘reload b’ followed by ‘reload a’. If you've got two modules which depend on each other, which is extremely common when those modules are part of the same package, you can't reload them both: if you reload p.a it'll get a reference to the old p.b, and vice versa. The only way to do it is to unload them both at once by deleting their items from sys.modules, before importing them again. This is icky and has some practical pitfalls to do with modules entries being None as a failed-relative-import marker.

And if you've got a module which passes references to its objects to system modules — for example it registers a codec, or adds a warnings handler — you're stuck; you can't reload the system module without confusing the rest of the Python environment.

In summary: for all but the simplest case of one self-contained module being loaded by one standalone script, reload() is very tricky to get right; if, as you imply, you are using a ‘package’, you will probably be better off continuing to cycle the interpreter.

I would suggest using the keyup event something like below:

$('elementName').keyup(function() {
 alert("Key up detected");
});

There are a few ways of achieving the same result so I guess it's down to preference and depends on how you want it to work exactly.

Update: This only works for manual input not copy and paste.

For copy and paste I would recommend the following:

$('elementName').on('input',function(e){
 // Code here
});

I got this solution. Does this help you ?

This is how you do a distinct count query. Note that you have to filter out the nulls.

var useranswercount = (from a in tpoll_answer
where user_nbr != null && answer_nbr != null
select user_nbr).Distinct().Count();

If you combine this with into your current grouping code, I think you'll have your solution.

If you are trying to do something very similar: a is not None, the same issue comes up. That is, Numpy complains that one must use a.any or a.all.

A workaround is to do:

if not (a is None):
    pass

Not too pretty, but it does the job.

I just ran into this. As mentioned in this answer, using mode: "no-cors" will give you an opaque response, which doesn't seem to return data in the body.

opaque: Response for “no-cors” request to cross-origin resource. Severely restricted.

In my case I was using Express. After I installed cors for Express and configured it and removed mode: "no-cors", I was returned a promise. The response data will be in the promise, e.g.

fetch('http://example.com/api/node', {
  // mode: 'no-cors',
  method: 'GET',
  headers: {
    Accept: 'application/json',
  },
},
).then(response => {
  if (response.ok) {
    response.json().then(json => {
      console.log(json);
    });
  }
});

This will give you accurate result :

if ((expiryDate.Date - DateTime.Now.Date).Days < 30)
    matchFound = true;

Well, first of all, you're wasting memory with the new HashMap creation call. Your second line completely disregards the reference to this created hashmap, making it then available to the garbage collector. So, don't do that, use:

private Map<String, String> someMap = (HashMap<String, String>)getApplicationContext().getBean("someMap");

Secondly, the compiler is complaining that you cast the object to a HashMap without checking if it is a HashMap. But, even if you were to do:

if(getApplicationContext().getBean("someMap") instanceof HashMap) {
    private Map<String, String> someMap = (HashMap<String, String>)getApplicationContext().getBean("someMap");
}

You would probably still get this warning. The problem is, getBean returns Object, so it is unknown what the type is. Converting it to HashMap directly would not cause the problem with the second case (and perhaps there would not be a warning in the first case, I'm not sure how pedantic the Java compiler is with warnings for Java 5). However, you are converting it to a HashMap<String, String>.

HashMaps are really maps that take an object as a key and have an object as a value, HashMap<Object, Object> if you will. Thus, there is no guarantee that when you get your bean that it can be represented as a HashMap<String, String> because you could have HashMap<Date, Calendar> because the non-generic representation that is returned can have any objects.

If the code compiles, and you can execute String value = map.get("thisString"); without any errors, don't worry about this warning. But if the map isn't completely of string keys to string values, you will get a ClassCastException at runtime, because the generics cannot block this from happening in this case.

I don't think you can turn JavaScript objects into JSON strings using only jQuery, assuming you need the JSON string as output.

Depending on the browsers you are targeting, you can use the JSON.stringify function to produce JSON strings.

See http://www.json.org/js.html for more information, there you can also find a JSON parser for older browsers that don't support the JSON object natively.

In your case:

var array = [];
$("input[class=email]").each(function() {
    array.push({
        title: $(this).attr("title"),
        email: $(this).val()
    });
});
// then to get the JSON string
var jsonString = JSON.stringify(array);

If you are not allowed to use C++'s string class (which is terrible teaching C++ imho), a raw, safe array version would look something like this.

#include <cstring>
#include <iostream>

int main()
{
    char array1[] ="The dog jumps ";
    char array2[] = "over the log";
    char * newArray = new char[std::strlen(array1)+std::strlen(array2)+1];
    std::strcpy(newArray,array1);
    std::strcat(newArray,array2);
    std::cout << newArray << std::endl;
    delete [] newArray;
    return 0;
}

This assures you have enough space in the array you're doing the concatenation to, without assuming some predefined MAX_SIZE. The only requirement is that your strings are null-terminated, which is usually the case unless you're doing some weird fixed-size string hacking.

Edit, a safe version with the "enough buffer space" assumption:

#include <cstring>
#include <iostream>

int main()
{
    const unsigned BUFFER_SIZE = 50;
    char array1[BUFFER_SIZE];
    std::strncpy(array1, "The dog jumps ", BUFFER_SIZE-1); //-1 for null-termination
    char array2[] = "over the log";
    std::strncat(array1,array2,BUFFER_SIZE-strlen(array1)-1); //-1 for null-termination
    std::cout << array1 << std::endl;
    return 0;
}

You can try the method shown below. In this method, you will have the freedom to specify/input the number of variables that you wish to enter.

mydict = {0:"c", 1:"d", 2:"e", 3:"f"}
mylist= []

num_var = int(raw_input("How many variables? ")) #Enter 3 when asked for input.

for i in range(num_var): 
    ''' Enter 0 as first input, 1 as second input and 3 as third input.'''
    globals()['var'+str('i').zfill(3)] = int(raw_input("Enter an integer between 0 and 3 "))
    mylist += mydict[globals()['var'+str('i').zfill(3)]]

print mylist
>>> ['c', 'd', 'f']

DO NOT USE MYSQL ANY MORE. If you must use mysqli but PDO is best:

$pdo = new PDO($dsn, $username, $pdo); // proper PDO init string here
if ($pdo->query("SELECT table_name FROM INFORMATION_SCHEMA.TABLES WHERE table_schema = 'db_name'")->fetch()) // table exists.

In case, anyone is here looking for solution on React JS SPA with Laravel. The accepted answer is the best explanation of why such problems happen. As already explained you have to configure both client side and server side. In your blade template, include the js bundled file, make sure to use URL facade like this

<script src="{{ URL::to('js/user/spa.js') }}"></script>

In your routes, make sure add this to the main endpoint where the blade template is. For example,

Route::get('/setting-alerts', function () {
   return view('user.set-alerts');
});

The above is the main endpoint for the blade template. Now add an optional route too,

Route::get('/setting-alerts/{spa?}', function () {
  return view('user.set-alerts');
});

The problem that happens is that first the blade template is loaded, then the react router. So, when you're loading '/setting-alerts', it loads the html and the js. But when you load '/setting-alerts/about', it first loads on the server side. Since on the server side, there is nothing on this location, it returns not found. When you have that optional router, it loads that same page and react router is also loaded, then react loader decides which component to show. Hope this helps.

On your development machine, you can execute the program and run Sysinternals Process Explorer. In the lower pane, it will show you the loaded DLLs and the current paths to them which is handy for a number of reasons. If you are executing off your deployment package, it would reveal which DLLs are referenced in the wrong path (i.e. weren't packaged correctly).

Currently, our company uses Visual Studio Installer projects to walk the dependency tree and output as loose files the program. In VS2013, this is now an extension: https://visualstudiogallery.msdn.microsoft.com/9abe329c-9bba-44a1-be59-0fbf6151054d. We then package these loose files in a more comprehensive installer but at least that setup project all the dot net dependencies and drops them into the one spot and warns you when things are missing.

If you want to hover the popover itself as well you have to use a manual trigger.

This is what i came up with:

function enableThumbPopover() {
    var counter;

    $('.thumbcontainer').popover({
        trigger: 'manual',
        animation: false,
        html: true,
        title: function () {
            return $(this).parent().find('.thumbPopover > .title').html();
        },
        content: function () {
            return $(this).parent().find('.thumbPopover > .body').html();
        },
        container: 'body',
        placement: 'auto'
    }).on("mouseenter",function () {
        var _this = this; // thumbcontainer

        console.log('thumbcontainer mouseenter')
        // clear the counter
        clearTimeout(counter);
        // Close all other Popovers
        $('.thumbcontainer').not(_this).popover('hide');

        // start new timeout to show popover
        counter = setTimeout(function(){
            if($(_this).is(':hover'))
            {
                $(_this).popover("show");
            }
            $(".popover").on("mouseleave", function () {
                $('.thumbcontainer').popover('hide');
            });
        }, 400);

    }).on("mouseleave", function () {
        var _this = this;

        setTimeout(function () {
            if (!$(".popover:hover").length) {
                if(!$(_this).is(':hover')) // change $(this) to $(_this) 
                {
                    $(_this).popover('hide');
                }
            }
        }, 200);
    });
}

Send User to Settings With located Package, example for WRITE_SETTINGS permission:

startActivityForResult(new Intent(Settings.ACTION_MANAGE_WRITE_SETTINGS).setData(Uri.parse("package:"+getPackageName()) ),0);

For passing multiple array data from controller to view, try it. It is working. In this example, I am passing subject details from a table and subject details contain category id, the details like name if category id is fetched from another table category.

$category = Category::all();
$category = Category::pluck('name', 'id');
$item = Subject::find($id);
return View::make('subject.edit')->with(array('item'=>$item, 'category'=>$category));

You need to make the members in the for the form class either public or, if the service class is in the same assembly, internal. Windows controls' visibility can be controlled through their Modifiers properties.

Note that it's generally considered a bad practice to explicitly tie a service class to a UI class. Rather you should create good interfaces between the service class and the form class. That said, for learning or just generally messing around, the earth won't spin off its axis if you expose form members for service classes.

I had a similar issue. I needed to keep the legacy encrypted passwords (Base64/SHA-1/Random salt Encoded) as users will not want to change their passwords or re-register. However I wanted to use the BCrypt encoder moving forward too.

My solution was to write a bespoke decoder that checks to see which encryption method was used first before matching (BCrypted ones start with $).

To get around the salt issue, I pass into the decoder a concatenated String of salt + encrypted password via my modified user object.

Decoder

@Component
public class LegacyEncoder implements PasswordEncoder {

    private static final String BCRYP_TYPE = "$";
    private static final PasswordEncoder BCRYPT = new BCryptPasswordEncoder();

    @Override
    public String encode(CharSequence rawPassword) {

    return BCRYPT.encode(rawPassword);
    }

    @Override
    public boolean matches(CharSequence rawPassword, String encodedPassword) {

    if (encodedPassword.startsWith(BCRYP_TYPE)) {
        return BCRYPT.matches(rawPassword, encodedPassword);
    }

    return sha1SaltMatch(rawPassword, encodedPassword);
    }

    @SneakyThrows
    private boolean sha1SaltMatch(CharSequence rawPassword, String encodedPassword) {

    String[] saltHash = encodedPassword.split(User.SPLIT_CHAR);

    // Legacy code from old system   
    byte[] b64salt = Base64.getDecoder().decode(saltHash[0].getBytes());
    byte[] validHash = Base64.getDecoder().decode(saltHash[1]);
    byte[] checkHash = Utility.getHash(5, rawPassword.toString(), b64salt);

    return Arrays.equals(checkHash, validHash);
    }

}

User Object

public class User implements UserDetails {

    public static final String SPLIT_CHAR = ":";

    @Id
    @Column(name = "user_id", nullable = false)
    private Integer userId;

    @Column(nullable = false, length = 60)
    private String password;

    @Column(nullable = true, length = 32)
    private String salt;

.
.

    @PostLoad
    private void init() {

    username = emailAddress; //To comply with UserDetails
    password = salt == null ? password : salt + SPLIT_CHAR + password;
    }        

You can also add a hook to re-encode the password in the new BCrypt format and replace it. Thus phasing out the old method.

You use an enum instead of a class if the class should have a fixed enumerable number of instances.

Examples:

• DayOfWeek  = 7 instances ? enum
• CardSuit    = 4 instances ? enum
• Singleton  = 1 instance   ? enum
  
  
• Product      = variable number of instances ? class
• User            = variable number of instances ? class
• Date            = variable number of instances ? class

It sets the default collation for the table; if you create a new column, that should be collated with latin_general_ci -- I think. Try specifying the collation for the individual column and see if that works. MySQL has some really bizarre behavior in regards to the way it handles this.

You can get it in the following manner:

NSInteger row;
NSArray *repeatPickerData;
UIPickerView *repeatPickerView;

row = [repeatPickerView selectedRowInComponent:0];
self.strPrintRepeat = [repeatPickerData objectAtIndex:row];

It can be caused by a classpath contamination. Check that you /WEB-INF/lib doesn't contain something like jsp-api-*.jar.

I realize I am a little late here, (5 years or so), but I think there is a better answer than the accepted one as follows:

$("#addComment").click(function() {
    if(typeof TinyMCE === "undefined") {
        $.ajax({
            url: "tinymce.js",
            dataType: "script",
            cache: true,
            success: function() {
                TinyMCE.init();
            }
        });
    }
});

The getScript() function actually prevents browser caching. If you run a trace you will see the script is loaded with a URL that includes a timestamp parameter:

http://www.yoursite.com/js/tinymce.js?_=1399055841840

If a user clicks the #addComment link multiple times, tinymce.js will be re-loaded from a differently timestampped URL. This defeats the purpose of browser caching.

===

Alternatively, in the getScript() documentation there is a some sample code that demonstrates how to enable caching by creating a custom cachedScript() function as follows:

jQuery.cachedScript = function( url, options ) {

    // Allow user to set any option except for dataType, cache, and url
    options = $.extend( options || {}, {
        dataType: "script",
        cache: true,
        url: url
    });

    // Use $.ajax() since it is more flexible than $.getScript
    // Return the jqXHR object so we can chain callbacks
    return jQuery.ajax( options );
};

// Usage
$.cachedScript( "ajax/test.js" ).done(function( script, textStatus ) {
    console.log( textStatus );
});

===

Or, if you want to disable caching globally, you can do so using ajaxSetup() as follows:

$.ajaxSetup({
    cache: true
});

An easy way to perform an if in lambda is by using list comprehension.

You can't raise an exception in lambda, but this is a way in Python 3.x to do something close to your example:

f = lambda x: print(x) if x==2 else print("exception")

Another example:

return 1 if M otherwise 0

f = lambda x: 1 if x=="M" else 0

Try this:

DEMO

<div class="container-fluid"> <!-- If Needed Left and Right Padding in 'md' and 'lg' screen means use container class -->
            <div class="row">
                <div class="col-xs-4 col-sm-4 col-md-4 col-lg-4">
                    <a href="#">About</a>
                </div>
                <div class="col-xs-4 col-sm-4 col-md-4 col-lg-4">
                    <img src="image.png" />
                </div>
                <div class="col-xs-4 col-sm-4 col-md-4 col-lg-4">
                    <a href="#myModal1" data-toggle="modal">SHARE</a>
                </div>
            </div>
        </div>

I just want to add what solved this problem for me, as it is different to all of the above answers.

The ajax calls that were causing the problem were trying to pass an empty data object. It seems IE does not like this, but other browsers don't mind.

To fix it I simply removed data: {}, from the ajax call.

TLDR: Use map (returning undefined when needed) and then filter.

First, I believe that a map + filter function is useful since you don't want to repeat a computation in both. Swift originally called this function flatMap but then renamed it to compactMap.

For example, if we don't have a compactMap function, we might end up with computation defined twice:

  let array = [1, 2, 3, 4, 5, 6, 7, 8];
  let mapped = array
  .filter(x => {
    let computation = x / 2 + 1;
    let isIncluded = computation % 2 === 0;
    return isIncluded;
  })
  .map(x => {
    let computation = x / 2 + 1;
    return `${x} is included because ${computation} is even`
  })

  // Output: [2 is included because 2 is even, 6 is included because 4 is even]

Thus compactMap would be useful to reduce duplicate code.

A really simple way to do something similar to compactMap is to:

1. Map on real values or undefined.
2. Filter out all the undefined values.

This of course relies on you never needing to return undefined values as part of your original map function.

Example:

  let array = [1, 2, 3, 4, 5, 6, 7, 8];
  let mapped = array
  .map(x => {
    let computation = x / 2 + 1;
    let isIncluded = computation % 2 === 0;
    if (isIncluded) {
      return `${x} is included because ${computation} is even`
    } else {
      return undefined
    }
  })
  .filter(x => typeof x !== "undefined")

If you type the executable name and a /? switch at the command line, there is typically help information available. Doing so with taskkill /? provides the following, for instance:

TASKKILL [/S system [/U username [/P [password]]]]
         { [/FI filter] [/PID processid | /IM imagename] } [/T] [/F]

Description:
    This tool is used to terminate tasks by process id (PID) or image name.

Parameter List:
    /S    system           Specifies the remote system to connect to.

    /U    [domain\]user    Specifies the user context under which the
                           command should execute.

    /P    [password]       Specifies the password for the given user
                           context. Prompts for input if omitted.

    /FI   filter           Applies a filter to select a set of tasks.
                           Allows "*" to be used. ex. imagename eq acme*

    /PID  processid        Specifies the PID of the process to be terminated.
                           Use TaskList to get the PID.

    /IM   imagename        Specifies the image name of the process
                           to be terminated. Wildcard '*' can be used
                           to specify all tasks or image names.

    /T                     Terminates the specified process and any
                           child processes which were started by it.

    /F                     Specifies to forcefully terminate the process(es).

    /?                     Displays this help message.

Filters:
    Filter Name   Valid Operators           Valid Value(s)
    -----------   ---------------           -------------------------
    STATUS        eq, ne                    RUNNING |
                                            NOT RESPONDING | UNKNOWN
    IMAGENAME     eq, ne                    Image name
    PID           eq, ne, gt, lt, ge, le    PID value
    SESSION       eq, ne, gt, lt, ge, le    Session number.
    CPUTIME       eq, ne, gt, lt, ge, le    CPU time in the format
                                            of hh:mm:ss.
                                            hh - hours,
                                            mm - minutes, ss - seconds
    MEMUSAGE      eq, ne, gt, lt, ge, le    Memory usage in KB
    USERNAME      eq, ne                    User name in [domain\]user
                                            format
    MODULES       eq, ne                    DLL name
    SERVICES      eq, ne                    Service name
    WINDOWTITLE   eq, ne                    Window title

    NOTE
    ----
    1) Wildcard '*' for /IM switch is accepted only when a filter is applied.
    2) Termination of remote processes will always be done forcefully (/F).
    3) "WINDOWTITLE" and "STATUS" filters are not considered when a remote
       machine is specified.

Examples:
    TASKKILL /IM notepad.exe
    TASKKILL /PID 1230 /PID 1241 /PID 1253 /T
    TASKKILL /F /IM cmd.exe /T 
    TASKKILL /F /FI "PID ge 1000" /FI "WINDOWTITLE ne untitle*"
    TASKKILL /F /FI "USERNAME eq NT AUTHORITY\SYSTEM" /IM notepad.exe
    TASKKILL /S system /U domain\username /FI "USERNAME ne NT*" /IM *
    TASKKILL /S system /U username /P password /FI "IMAGENAME eq note*"

You can also find this information, as well as documentation for most of the other command-line utilities, in the Microsoft TechNet Command-Line Reference

When changing icon size with UIEdgeInsetsMake(top, left, bottom, right), keep in mind button dimensions and the ability of UIEdgeInsetsMake to work with negative values as if they are positive.

Example: Two buttons with height 100 and aspect 1:1.

left.imageEdgeInsets = UIEdgeInsetsMake(40, 0, 40, 0)
right.imageEdgeInsets = UIEdgeInsetsMake(40, 0, 40, 0)

left.imageEdgeInsets = UIEdgeInsetsMake(40, 0, 40, 0)
right.imageEdgeInsets = UIEdgeInsetsMake(45, 0, 45, 0)

left.imageEdgeInsets = UIEdgeInsetsMake(40, 0, 40, 0)
right.imageEdgeInsets = UIEdgeInsetsMake(60, 0, 60, 0)

Examples 1 and 3 are identical since ABS(100 - (40 + 40)) = ABS(100 - (60 + 60))

If you are using SQL server 2016 or higher and if your table is having partitions created based on column you are trying to delete(for example Timestamp column), then you could use this new command to delete data by partitions.

TRUNCATE TABLE WITH ( PARTITIONS ( { | } [ , ...n ] ) )

This will delete the data in selected partition(s) only and should be the most efficient way to delete data from part of table since it will not create transaction logs and will be done just as fast as regular truncate but without having all the data deleted from the table.

Drawback is if your table is not setup with partition, then you need to go old school and delete the data with regular approach and then recreate the table with partitions so that you can do this in future, which is what I did. I added the partition creation and deletion into insertion procedure itself. I had table with 500 million rows so this was the only option to reduce deletion time.

For more details refer to below links: https://docs.microsoft.com/en-us/sql/t-sql/statements/truncate-table-transact-sql?view=sql-server-2017

All other answers already give almost everything... Just a little addition.

If you want some more IDE-like debugger (non-CLI) and are not afraid of using Vim as editor, I suggest Vim Ruby Debugger plugin for it.

Its documentation is pretty straightforward, so follow the link and see. In short, it allows you to set breakpoint at current line in editor, view local variables in nifty window on pause, step over/into — almost all usual debugger features.

For me it was pretty enjoyable to use this vim debugger for debugging a Rails app, although rich logger abilities of Rails almost eliminates the need for it.

Well, you can't add styling using pseudo selectors like :hover, :after, :nth-child, or anything like that using jQuery.

If you want to add a CSS rule like that you have to create a <style> element and add that :hover rule to it just like you would in CSS. Then you would have to add that <style> element to the page.

Using the .hover function seems to be more appropriate if you can't just add the css to a stylesheet, but if you insist you can do:

$('head').append('<style>.myclass:hover div {background-color : red;}</style>')

If you want to read more on adding CSS with javascript you can check out one of David Walsh's Blog posts.

In the Trace properties, click the Events Selection tab at the top next to General. Then click Column Filters... at the bottom right. You can then select what to filter, such as TextData or DatabaseName.

Expand the Like node and enter your filter with the percentage % signs like %MyDatabaseName% or %TextDataToFilter%. Without the %% signs the filter will not work.

Also, make sure to check the checkbox Exclude rows that do not contain values' If you cannot find the field you are looking to filter such as DatabaseName go to the General tab and change your Template, blank one should contain all the fields.

.*

. is any char, * means repeated zero or more times.

When changing fonts in XCode from [Preferences] (after duplicating a template that matches colours close to what you want), you can select multiple entries and change the fonts all at once. Use [shift] to select a range or [cmd] to select multiple individual entries (e.g. you might select both 'comments' and 'strings' and change only their fonts).

I would suggest the open-source library CSharpOptParse. It parses the command line and hydrates a user-defined .NET object with the command-line input. I always turn to this library when writing a C# console application.

CryptoJS is a crypto library which can generate md5 hash among others:

Usage with Script tag:

<script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/4.0.0/core.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.9-1/md5.js"></script>
<script>
   var hash = CryptoJS.MD5("Message");
   alert(hash);
</script>

Alternatively with ES6:

npm install crypto-js

import MD5 from "crypto-js/md5";
console.log(MD5("Message").toString());

You can also use modular imports:

var MD5 = require("crypto-js/md5");
console.log(MD5("Message").toString());

you attach the .onerror handler to the ajax object, why people insist on posting JQuery for responses when vanila works cross platform...

quickie example:

ajax = new XMLHttpRequest();

To use Redux-saga is the best middleware in React-redux implementation.

Ex: store.js

  import createSagaMiddleware from 'redux-saga';
  import { createStore, applyMiddleware } from 'redux';
  import allReducer from '../reducer/allReducer';
  import rootSaga from '../saga';

  const sagaMiddleware = createSagaMiddleware();
  const store = createStore(
     allReducer,
     applyMiddleware(sagaMiddleware)
   )

   sagaMiddleware.run(rootSaga);

 export default store;

And then saga.js

import {takeLatest,delay} from 'redux-saga';
import {call, put, take, select} from 'redux-saga/effects';
import { push } from 'react-router-redux';
import data from './data.json';

export function* updateLesson(){
   try{
       yield put({type:'INITIAL_DATA',payload:data}) // initial data from json
       yield* takeLatest('UPDATE_DETAIL',updateDetail) // listen to your action.js 
   }
   catch(e){
      console.log("error",e)
     }
  }

export function* updateDetail(action) {
  try{
       //To write store update details
   }  
    catch(e){
       console.log("error",e)
    } 
 }

export default function* rootSaga(){
    yield [
        updateLesson()
       ]
    }

And then action.js

 export default function updateFruit(props,fruit) {
    return (
       {
         type:"UPDATE_DETAIL",
         payload:fruit,
         props:props
       }
     )
  }

And then reducer.js

import {combineReducers} from 'redux';

const fetchInitialData = (state=[],action) => {
    switch(action.type){
      case "INITIAL_DATA":
          return ({type:action.type, payload:action.payload});
          break;
      }
     return state;
  }
 const updateDetailsData = (state=[],action) => {
    switch(action.type){
      case "INITIAL_DATA":
          return ({type:action.type, payload:action.payload});
          break;
      }
     return state;
  }
const allReducers =combineReducers({
   data:fetchInitialData,
   updateDetailsData
 })
export default allReducers; 

And then main.js

import React from 'react';
import ReactDOM from 'react-dom';
import App from './app/components/App.jsx';
import {Provider} from 'react-redux';
import store from './app/store';
import createRoutes from './app/routes';

const initialState = {};
const store = configureStore(initialState, browserHistory);

ReactDOM.render(
       <Provider store={store}>
          <App />  /*is your Component*/
       </Provider>, 
document.getElementById('app'));

try this.. is working

for guzzle you can try this :

$client = new Client(env('API_HOST'));
$client->setSslVerification(false);

tested on guzzle/guzzle 3.*

One more possibility to check. Listing here because it just happened to me and wasn't mentioned;-)

I had accidentally added a space character on the end of the name. Many hours of trying things before I finally noticed it. It's always something simple after you figure it out.

you can use the remove() function of the example below and build table again with table head, and table body

$("#table_id  thead").remove();
$("#table_id  tbody").remove();

Try the file command with -i option.

-i option Causes the file command to output mime type strings rather than the more traditional human readable ones. Thus it may say text/plain; charset=us-ascii rather than ASCII text.

I had a read of the spec and did some testing in Chrome, and if you catch the "invalid" event and return false that seems to allow form submission.

I am using jquery, with this HTML.

// suppress "invalid" events on URL inputs_x000D_
$('input[type="url"]').bind('invalid', function() {_x000D_
  alert('invalid');_x000D_
  return false;_x000D_
});_x000D_
_x000D_
document.forms[0].onsubmit = function () {_x000D_
  alert('form submitted');_x000D_
};

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<form>_x000D_
  <input type="url" value="http://" />_x000D_
  <button type="submit">Submit</button>_x000D_
</form>

I haven't tested this in any other browsers.

Glide is a really elegant package management for Go especially if you come from Node's npm or Rust's cargo.

It behaves closely to Godep's new vendor feature in 1.6 but is way more easier. Your dependencies and versions are "locked" inside your projectdir/vendor directory without relying on GOPATH.

Install with brew (OS X)

$ brew install glide

Init the glide.yaml file (akin to package.json). This also grabs the existing imported packages in your project from GOPATH and copy then to the project's vendor/ directory.

$ glide init

Get new packages

$ glide get vcs/namespace/package

Update and lock the packages' versions. This creates glide.lock file in your project directory to lock the versions.

$ glide up

I tried glide and been happily using it for my current project.

Extend LinearLayout/RelativeLayout and use it straight on the XML

Read MSDN.

it also contains a link to the args.

short answer: no, the main does not get override. when visual studio (actually the compiler) builds your exe it must declare a starting point for the assmebly, that point is the main function.

if you meant how to literary pass args then you can either run you're app from the command line with them (e.g. appname.exe param1 param2) or in the project setup, enter them (in the command line arguments in the Debug tab)

in the main you will need to read those args for example:

for (int i = 0; i < args.Length; i++)
{
    string flag = args.GetValue(i).ToString();
    if (flag == "bla") 
    {
        Bla();
    }
}

First off, the arrays are pointless, let's get rid of them: all they are doing is providing values for mock data. How you construct mock objects has been debated ad nauseum, but clearly, the code to create the fake Athletes should be inside of a unit test. I would use Joshua Bloch's static builder for the Athlete class, but you only have two attributes right now, so just pass those in a Constructor. Would look like this:

class Athlete {

    private String name;
    private String country;

    private List<Dive> dives;

    public Athlete(String name, String country){
       this.name = name;
       this.country = country;
    }

    public String getName(){
        return this.name;
    }

    public String getCountry(){
        return this.country;
    }

    public String getDives(){
        return this.dives;
    }

    public void addDive(Dive dive){
        this.dives.add(dive);
    }
}

Then for the Dive class:

class Dive {

    private Athlete athlete;
    private Date date;
    private double score;

    public Dive(Athlete athlete, double score){
        this.athlete = athlete;
        this.score = score;
        this.date = new Date();
    }

    public Athlete getAthlete(){
        return this.athlete;
    }

    public Athlete getAthlete(){
        return this.athlete;
    }

    public Athlete getAthlete(){
        return this.athlete;
    }

}

Then make a unit test and just construct the classes, and manipulate them, make sure that they are working. Right now they don't do anything so all you could do is assert that they are retaining the Dives that you are putting in them. Example:

@Test
public void testThatDivesRetainInformation(){
    Athlete art = new Athlete("Art", "Canada");
    Dive art1 = new Dive(art, 8.5);
    Dive art2 = new Dive(art, 8.0);
    Dive art3 = new Dive(art, 8.8);
    Dive art4 = new Dive(art, 9.2);

    assertThat(art.getDives().size(), is(5));
    }

Then you could go through and add tests for things like, making sure that you can't construct a dive without an athlete, etc.

You could move construction of the athletes into the setup method of the test so you could use it all over the place. Most IDEs have support for doing that with a refactoring.

You could try returning a VBA Collection.

As long as you dealing with pair values, like "Version=1.31", you could store the identifier as a key ("Version") and the actual value (1.31) as the item itself.

Dim c As New Collection
Dim item as Variant
Dim key as String
key = "Version"
item = 1.31
c.Add item, key
'Then return c

Accessing the values after that it's a breeze:

c.Item("Version") 'Returns 1.31
or
c("Version") '.Item is the default member

Does it make sense?

One needs to install magrittr as follows

install.packages("magrittr")

Then, in one's script, don't forget to add on top

library(magrittr)

For the meaning of the operator %>% you might want to consider this question: What does %>% function mean in R?

Note that the same operator would also work with the library dplyr, as it imports from magrittr.

dplyr used to have a similar operator (%.%), which is now deprecated. Here we can read about the differences between %.% (deprecated operator from the library dplyr) and %>% (operator from magrittr, that is also available in dplyr)

?????? window.performance.navigation.type is deprecated, pls see ???? ????????'s answer

A better way to know that the page is actually reloaded is to use the navigator object that is supported by most modern browsers.

It uses the Navigation Timing API.

//check for Navigation Timing API support
if (window.performance) {
  console.info("window.performance works fine on this browser");
}
console.info(performance.navigation.type);
if (performance.navigation.type == performance.navigation.TYPE_RELOAD) {
  console.info( "This page is reloaded" );
} else {
  console.info( "This page is not reloaded");
}

I elected to conditionally alternate color and background. Setting a sort order and with vue.js, I did something like this:

<style>
    .altgroup_1 {background:gray; color:white;}
    .altgroup_2{background:white; color:black;}
</style>

<option :class = {
    'altgroup_1': (country.sort_order > 25),
    'altgroup_2': (country.sort_order > 50 }"
    value="{{ country.iso_short }}">
    {{ country.short_name }}
</option

Many of the examples here will not work for 11, 12, 13. This is more generic and will work for all case.

switch (date) {
                case 1:
                case 21:
                case 31:
                    return "" + date + "st";

                case 2:
                case 22:
                    return "" + date + "nd";

                case 3:
                case 23:
                    return "" + date + "rd";

                default:
                    return "" + date + "th";
}

Linux

php --info | grep error 

The terminal will output the error log location.

Windows

php --info | findstr /r /c:"error_log"

The command prompt will output the error log location

To set the log location

Open your php.ini and add the following line:

error_log = /log/myCustomLog.log

Defining complex directory trees with one command

mkdir -p project/{lib/ext,bin,src,doc/{html,info,pdf},demo/stat/a}

@tom-studee you were right, it's possible to do it in the data modeler.

Double click your table, then go to the column section. Here double click on the column which will have the auto increment. In the general section there is a checkbox "autoincrement", just tick it.

After that you can also go to the "autoincrement" section to customize it.

When you save it and ask the data modeler to generate the SQL script, you will see the sequence and trigger which represent your autoincrement.

Symptoms
You install an application that uses Microsoft Virtual WiFi technology on a computer that is running Windows 7 or Windows Server 2008 R2. However, the application does not work after the computer restarts. Additionally, you receive an error message that resembles the following:

The hosted network couldn't be started. The group or resource is not in the correct state to perform the requested operation.

Cause
This issue occurs because the Virtual Wi-Fi filter driver does not create the Virtual Wi-Fi Adapter correctly when a PNP resource rebalance occurs during the startup process.

Notes
1.This issue may occur when a Plug and Play (PNP) resource rebalance occurs during the startup process. The PNP resource rebalance is usually triggered by a change to the hardware configuration.
2.If you open Device Manager when this issue occurs, you notice that the Virtual WiFi Adapter is not created.

If you can't restart your hostednetwork after rebooting the OS ,just Try this hotfix .It fixed my problem. Or try to figure it out by yourself according to the Symptoms and Cause mentioned at the start of my answer.

Try the notepad++ plugin JSMinNpp(Changed name to JSTool since 1.15)

http://www.sunjw.us/jsminnpp/

if (myVar == undefined)

will work to see if the var is declared but not initalized.

CREATE GLOBAL TEMPORARY TABLE Table_name
    (startdate DATE,
     enddate DATE,
     class CHAR(20))
  ON COMMIT DELETE ROWS;

I would override your Tuple with a proper GetHashCode, and just use it as the key.

As long as you overload the proper methods, you should see decent performance.

You need to use "Authentication" as OAuth 2 and will be prompted to signin via Instagram. Post that you might have to reneter the "tag-name" in "Template" section.

All the pagination related data is available in the "pagination" parameter in the response and use it's "next_url" to query for the next set of result.

I believe you are looking for the outline CSS property (in conjunction with active and hover psuedo attributes):

/* turn it off completely */
select:active, select:hover {
  outline: none
}

/* make it red instead (with with same width and style) */
select:active, select:hover {
  outline-color: red
}

Full details of outline, outline-color, outline-style, and outline-width https://developer.mozilla.org/en-US/docs/Web/CSS/outline

linux: shutdown() causes listener thread select() to awake and produce error. shutdown(); close(); will lead to endless wait.

winsock: vice versa - shutdown() has no effect, while close() is successfully catched.

Since PowerShell can call .NET classes, you could do the following:

[System.Diagnostics.FileVersionInfo]::GetVersionInfo("somefilepath").FileVersion

Or as noted here on a list of files:

get-childitem * -include *.dll,*.exe | foreach-object { "{0}`t{1}" -f $_.Name, [System.Diagnostics.FileVersionInfo]::GetVersionInfo($_).FileVersion }

Or even nicer as a script: https://jtruher3.wordpress.com/2006/05/14/powershell-and-file-version-information/

Clearly you're passing in d.keys() to your shuffle function. Probably this was written with python2.x (when d.keys() returned a list). With python3.x, d.keys() returns a dict_keys object which behaves a lot more like a set than a list. As such, it can't be indexed.

The solution is to pass list(d.keys()) (or simply list(d)) to shuffle.

Adding this for diversity and clean approach.

This code uses functional style approach. I have used onresize instead of addEventListener as mentioned in other answers.

import { useState, useEffect } from "react";

export default function App() {
  const [size, setSize] = useState({
    x: window.innerWidth,
    y: window.innerHeight
  });
  const updateSize = () =>
    setSize({
      x: window.innerWidth,
      y: window.innerHeight
    });
  useEffect(() => (window.onresize = updateSize), []);
  return (
    <>
      <p>width is : {size.x}</p>
      <p>height is : {size.y}</p>
    </>
  );
}

You can center a fixed or absolute positioned element setting right and left to 0, and then margin-left & margin-right to auto as if you were centering a static positioned element.

#example {
    position: fixed;
    /* center the element */
    right: 0;
    left: 0;
    margin-right: auto;
    margin-left: auto;
    /* give it dimensions */
    min-height: 10em;
    width: 90%;
}

See this example working on this fiddle.

Your use case would be :

    $ArrayCollectionOfActiveUsers = $customer->users->filter(function($user) {
                        return $user->getActive() === TRUE;
                    });

if you add ->first() you'll get only the first entry returned, which is not what you want.

@ Sjwdavies You need to put () around the variable you pass to USE. You can also shorten as in_array return's a boolean already:

    $member->getComments()->filter( function($entry) use ($idsToFilter) {
        return in_array($entry->getId(), $idsToFilter);
    });

For turning off line numbers, any of these commands will work:

1. :set nu!
2. :set nonu
3. :set number!
4. :set nonumber

Use defaultdict

from collections import defaultdict
a = {} 
a = defaultdict(lambda:0,a)
a["anything"] # => 0

This is very useful for case like this,where default values for every key is set as 0:

results ={ 'pre-access' : {'count': 4, 'pass_count': 2},'no-access' : {'count': 55, 'pass_count': 19}
for k,v in results.iteritems():
  a['count'] += v['count']
  a['pass_count'] += v['pass_count']

Available Zoom Levels

Zoom level 0 is the most zoomed out zoom level available and each integer step in zoom level halves the X and Y extents of the view and doubles the linear resolution.

Google Maps was built on a 256x256 pixel tile system where zoom level 0 was a 256x256 pixel image of the whole earth. A 256x256 tile for zoom level 1 enlarges a 128x128 pixel region from zoom level 0.

As correctly stated by bkaid, the available zoom range depends on where you are looking and the kind of map you are using:

• Road maps - seem to go up to zoom level 22 everywhere
• Hybrid and satellite maps - the max available zoom levels depend on location. Here are some examples:
• Remote regions of Antarctica: 13
• Gobi Desert: 17
• Much of the U.S. and Europe: 21
• "Deep zoom" locations: 22-23 (see bkaid's link)

Note that these values are for the Google Static Maps API which seems to give one more zoom level than the Javascript API. It appears that the extra zoom level available for Static Maps is just an upsampled version of the max-resolution image from the Javascript API.

Map Scale at Various Zoom Levels

Google Maps uses a Mercator projection so the scale varies substantially with latitude. A formula for calculating the correct scale based on latitude is:

meters_per_pixel = 156543.03392 * Math.cos(latLng.lat() * Math.PI / 180) / Math.pow(2, zoom)

Formula is from Chris Broadfoot's comment.

What you're looking for are the scales for each zoom level. Use these:

20 : 1128.497220
19 : 2256.994440
18 : 4513.988880
17 : 9027.977761
16 : 18055.955520
15 : 36111.911040
14 : 72223.822090
13 : 144447.644200
12 : 288895.288400
11 : 577790.576700
10 : 1155581.153000
9  : 2311162.307000
8  : 4622324.614000
7  : 9244649.227000
6  : 18489298.450000
5  : 36978596.910000
4  : 73957193.820000
3  : 147914387.600000
2  : 295828775.300000
1  : 591657550.500000

ok, here is what i understood from your question. You are writing a csv file from python but when you are opening that file into some other application like excel or open office they are showing the complete row in one cell rather than each word in individual cell. I am right??

if i am then please try this,

import csv

with open(r"C:\\test.csv", "wb") as csv_file:
    writer = csv.writer(csv_file, delimiter =",",quoting=csv.QUOTE_MINIMAL)
    writer.writerow(["a","b"])

you have to set the delimiter = ","

This is a little function that prints colored text using bash scripting. You may add as many styles as you want, and even print tabs and new lines:

#!/bin/bash

# prints colored text
print_style () {

    if [ "$2" == "info" ] ; then
        COLOR="96m";
    elif [ "$2" == "success" ] ; then
        COLOR="92m";
    elif [ "$2" == "warning" ] ; then
        COLOR="93m";
    elif [ "$2" == "danger" ] ; then
        COLOR="91m";
    else #default color
        COLOR="0m";
    fi

    STARTCOLOR="\e[$COLOR";
    ENDCOLOR="\e[0m";

    printf "$STARTCOLOR%b$ENDCOLOR" "$1";
}

print_style "This is a green text " "success";
print_style "This is a yellow text " "warning";
print_style "This is a light blue with a \t tab " "info";
print_style "This is a red text with a \n new line " "danger";
print_style "This has no color";

This is the default working setup https://www.youtube.com/watch?v=XiD7JTCBdpI

Just a note which may be helpful- I was having this trouble with Apache on my laptop (which connects by wifi AFTER startup), and restarting the server (after connect) fixed the issue. I guess in my case this may be to do with apache starting offline and perhaps there noting that DNS lookups fail?

It's been a while but the question is still relevant, though the answer might have changed a bit.

An API Gateway would be a flexible and highly configurable solution. I tested and used KONG quite a bit and really liked what I saw. KONG provides an admin REST API of its own which you can use to manage users.

Express-gateway.io is more recent and is also an API Gateway.

Copying and pasting by user interactions emulation could be not reliable (for example, popup appears and it switches the focus). You may be interested in trying the commercial ByteScout PDF Extractor SDK that is specifically designed to extract data from PDF and it works from VBA. It is also capable of extracting data from invoices and tables as CSV using VB code.

Here is the VBA code for Excel to extract text from given locations and save them into cells in the Sheet1:

Private Sub CommandButton1_Click()

' Create TextExtractor object
' Set extractor = CreateObject("Bytescout.PDFExtractor.TextExtractor")
Dim extractor As New Bytescout_PDFExtractor.TextExtractor

extractor.RegistrationName = "demo"
extractor.RegistrationKey = "demo"

' Load sample PDF document
extractor.LoadDocumentFromFile ("c:\sample1.pdf")

' Get page count
pageCount = extractor.GetPageCount()

Dim wb As Workbook
Dim ws As Worksheet
Dim TxtRng  As Range

Set wb = ActiveWorkbook
Set ws = wb.Sheets("Sheet1")

For i = 0 To pageCount - 1
            RectLeft = 10
            RectTop = 10
            RectWidth = 100
            RectHeight = 100

            ' check the same text is extracted from returned coordinates
            extractor.SetExtractionArea RectLeft, RectTop, RectWidth, RectHeight
            ' extract text from given area
            extractedText = extractor.GetTextFromPage(i)

            ' insert rows
            ' Rows(1).Insert shift:=xlShiftDown
            ' write cell value
             Set TxtRng = ws.Range("A" & CStr(i + 2))
             TxtRng.Value = extractedText

Next

Set extractor = Nothing


End Sub

Add a hidden span above it, use ui-helper-hidden-accessible to make it hidden by absolute positioning. I know you have that class because you are using dialog from jquery-ui and it's in jquery-ui.

<span class="ui-helper-hidden-accessible"><input type="text"/></span>

Using attr() pointing to an external domain may trigger an error like this in Chrome: "Refused to display document because display forbidden by X-Frame-Options". The workaround to this can be to move the whole iframe HTML code into the script (eg. using .html() in jQuery).

Example:

var divMapLoaded = false;
$("#container").scroll(function() {
    if ((!divMapLoaded) && ($("#map").position().left <= $("#map").width())) {
    $("#map-iframe").html("<iframe id=\"map-iframe\" " +
        "width=\"100%\" height=\"100%\" frameborder=\"0\" scrolling=\"no\" " +
        "marginheight=\"0\" marginwidth=\"0\" " +
        "src=\"http://www.google.it/maps?t=m&amp;cid=0x3e589d98063177ab&amp;ie=UTF8&amp;iwloc=A&amp;brcurrent=5,0,1&amp;ll=41.123115,16.853177&amp;spn=0.005617,0.009943&amp;output=embed\"" +
        "></iframe>");
    divMapLoaded = true;
}

With bootstrap3-typeahead, I made it to work with the following code:

<input id="typeahead-input" type="text" data-provide="typeahead" />

<script type="text/javascript">
jQuery(document).ready(function() {
    $('#typeahead-input').typeahead({
        source: function (query, process) {
            return $.get('search?q=' + query, function (data) {
                return process(data.search_results);
            });
        }
    });
})
</script>

The backend provides search service under the search GET endpoint, receiving the query in the q parameter, and returns a JSON in the format { 'search_results': ['resultA', 'resultB', ... ] }. The elements of the search_resultsarray are displayed in the typeahead input.

<script src="https://cdn.datatables.net/1.10.22/js/jquery.dataTables.min.js"defer</script>

Add Defer to the end of your Script tag, it worked for me (;

Everything needs to be loaded in the correct order (:

i have tried with craeting a new object without deleting the coulmns in Vue.js.

let data =this.selectedContactsDto[];

//selectedContactsDto[] = object with list of array objects created in my project

console.log(data); let newDataObj= data.map(({groupsList,customFields,firstname, ...item }) => item); console.log("newDataObj",newDataObj);

There are two ways of doing it:

1. Submit the form to the same page: Handle the submitted form using PHP script. (This can be done by setting the form action to the current page URL.)

   if(isset($_POST['submit'])) {
       // Enter the code you want to execute after the form has been submitted
       // Display Success or Failure message (if any)
     } else {
       // Display the Form and the Submit Button
   }
   

2. Using AJAX Form Submission which is a little more difficult for a beginner than method #1.

With a BorderLayout you need to use setPreferredSize instead of setSize

You can use an iframe to display a preview of the page on mouseover:

.box{_x000D_
    display: none;_x000D_
    width: 100%;_x000D_
}_x000D_
_x000D_
a:hover + .box,.box:hover{_x000D_
    display: block;_x000D_
    position: relative;_x000D_
    z-index: 100;_x000D_
}

This live preview for <a href="https://en.wikipedia.org/">Wikipedia</a>_x000D_
  <div class="box">_x000D_
    <iframe src="https://en.wikipedia.org/" width = "500px" height = "500px">_x000D_
    </iframe>_x000D_
  </div> _x000D_
remains open on mouseover.

Here's an example with multiple live previews:

Works for any number from 0 to 999999999.

This program gets a number from the user, divides it into three parts and stores them separately in an array. The three numbers are passed through a function that convert them into words. Then it adds "million" to the first part and "thousand" to the second part.

#include <iostream>
using namespace std;
int buffer = 0, partFunc[3] = {0, 0, 0}, part[3] = {0, 0, 0}, a, b, c, d;
long input, nFake = 0;
const char ones[][20] = {"",       "one",       "two",      "three",
                         "four",    "five",      "six",      "seven",
                         "eight",   "nine",      "ten",      "eleven",
                         "twelve",  "thirteen",  "fourteen", "fifteen",
                         "sixteen", "seventeen", "eighteen", "nineteen"};
const char tens[][20] = {"",     "ten",   "twenty",  "thirty", "forty",
                         "fifty", "sixty", "seventy", "eighty", "ninety"};
void convert(int funcVar);
int main() {
  cout << "Enter the number:";
  cin >> input;
  nFake = input;
  buffer = 0;
  while (nFake) {
    part[buffer] = nFake % 1000;
    nFake /= 1000;
    buffer++;
  }
  if (buffer == 0) {
    cout << "Zero.";
  } else if (buffer == 1) {
    convert(part[0]);
  } else if (buffer == 2) {
    convert(part[1]);
    cout << " thousand,";
    convert(part[0]);
  } else {
    convert(part[2]);
    cout << " million,";

    if (part[1]) {
      convert(part[1]);
      cout << " thousand,";
    } else {
      cout << "";
    }
    convert(part[0]);

    else {
      c = b / 10;
      cout << " " << tens[c];
      d = b % 10;
      cout << " " << ones[d];
    }
  } else {
    b = funcVar;
    if (b < 20)
      cout << ones[b];

Did your server use the new registration ID returned by the GCM server to your app? I had this problem, if trying to send a message to registration IDs that are given out by the old C2DM server.

And also double check the Sender ID and API_KEY, they must match or else you will get that MismatchSenderId error. In the Google API Console, look at the URL of your project:

https://code.google.com/apis/console/#project:xxxxxxxxxxx

The xxxxxxxxx is the project ID, which is the sender ID.

And make sure the API Key belongs to 'Key for server apps (with IP locking)'

UPDATE totals 
   SET total = total + 1
WHERE name = 'bill';

If you want to make sure the current value is indeed 203 (and not accidently increase it again) you can also add another condition:

UPDATE totals 
   SET total = total + 1
WHERE name = 'bill'
  AND total = 203;

Am I doing that right, as far as iterating through the Arraylist goes?

No: by calling iterator twice in each iteration, you're getting new iterators all the time.

The easiest way to write this loop is using the for-each construct:

for (String s : arrayList)
    if (s.equals(value))
        // ...

As for

java.lang.ArrayIndexOutOfBoundsException: -1

You just tried to get element number -1 from an array. Counting starts at zero.

I would just raise ValueError, unless you need a more specific exception..

def import_to_orm(name, save=False, recurse=False):
    if recurse and not save:
        raise ValueError("save must be True if recurse is True")

There's really no point in doing class BadValueError(ValueError):pass - your custom class is identical in use to ValueError, so why not use that?

When initializing an array, C allows you to fill it with values. So

char s[100] = "abcd";

is basically the same as

int s[3] = { 1, 2, 3 };

but it doesn't allow you to do the assignment since s is an array and not a free pointer. The meaning of

s = "abcd" 

is to assign the pointer value of abcd to s but you can't change s since then nothing will be pointing to the array.
This can and does work if s is a char* - a pointer that can point to anything.

If you want to copy the string simple use strcpy.

As others have said, @Transient is used to mark fields which shouldn't be persisted. Consider this short example:

public enum Gender { MALE, FEMALE, UNKNOWN }

@Entity
public Person {
    private Gender g;
    private long id;

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    public long getId() { return id; }
    public void setId(long id) { this.id = id; }

    public Gender getGender() { return g; }    
    public void setGender(Gender g) { this.g = g; }

    @Transient
    public boolean isMale() {
        return Gender.MALE.equals(g);
    }

    @Transient
    public boolean isFemale() {
        return Gender.FEMALE.equals(g);
    }
}

When this class is fed to the JPA, it persists the gender and id but doesn't try to persist the helper boolean methods - without @Transient the underlying system would complain that the Entity class Person is missing setMale() and setFemale() methods and thus wouldn't persist Person at all.

On the outermost level, a JSON object starts with a { and end with a }.

Sample data:

{
    "cars": {
        "Nissan": [
            {"model":"Sentra", "doors":4},
            {"model":"Maxima", "doors":4},
            {"model":"Skyline", "doors":2}
        ],
        "Ford": [
            {"model":"Taurus", "doors":4},
            {"model":"Escort", "doors":4}
        ]
    }
}

If the JSON is assigned to a variable called data, then accessing it would be like the following:

data.cars['Nissan'][0].model   // Sentra
data.cars['Nissan'][1].model   // Maxima
data.cars['Nissan'][2].doors   // 2

for (var make in data.cars) {
    for (var i = 0; i < data.cars[make].length; i++) {
        var model = data.cars[make][i].model;
        var doors = data.cars[make][i].doors;
        alert(make + ', ' + model + ', ' + doors);
    }
}

Another approach (using an associative array for car models rather than an indexed array):

{
    "cars": {
        "Nissan": {
            "Sentra": {"doors":4, "transmission":"automatic"},
            "Maxima": {"doors":4, "transmission":"automatic"}
        },
        "Ford": {
            "Taurus": {"doors":4, "transmission":"automatic"},
            "Escort": {"doors":4, "transmission":"automatic"}
        }
    }
}

data.cars['Nissan']['Sentra'].doors   // 4
data.cars['Nissan']['Maxima'].doors   // 4
data.cars['Nissan']['Maxima'].transmission   // automatic

for (var make in data.cars) {
    for (var model in data.cars[make]) {
        var doors = data.cars[make][model].doors;
        alert(make + ', ' + model + ', ' + doors);
    }
}

Edit:

Correction: A JSON object starts with { and ends with }, but it's also valid to have a JSON array (on the outermost level), that starts with [ and ends with ].

Also, significant syntax errors in the original JSON data have been corrected: All key names in a JSON object must be in double quotes, and all string values in a JSON object or a JSON array must be in double quotes as well.

See:

• JSON specification
• JSONLint - The JSON validator

I just got the same situation, Factory data reset worked well for me.

StringTokenizer was always there. It is the fastest of all, but the enumeration-like idiom might not look as elegant as the others.

split came to existence on JDK 1.4. Slower than tokenizer but easier to use, since it is callable from the String class.

Scanner came to be on JDK 1.5. It is the most flexible and fills a long standing gap on the Java API to support an equivalent of the famous Cs scanf function family.

You can use date to get time and date of a day:

[pengyu@GLaDOS ~]$date
Tue Aug 27 15:01:27 CST 2013

Also hwclock would do:

[pengyu@GLaDOS ~]$hwclock
Tue 27 Aug 2013 03:01:29 PM CST  -0.516080 seconds

For customized output, you can either redirect the output of date to something like awk, or write your own program to do that.

Remember to put your own executable scripts/binary into your PATH (e.g. /usr/bin) to make it invokable anywhere.

Frame its relative to its SuperView whereas Bounds relative to its NSView.

Example:X=40,Y=60.Also contains 3 Views.This Diagram shows you clear idea.

You can go for this :

getActivity().getSystemService(Context.CONNECTIVITY_SERVICE);

This is a paragraph option. Go to Window>Paragraph then a small window will pop up. You will have two buttons on the bottom. One with a arrow on the left of P and one on the right. Select the right one.

For Western Arabic numbers (0-9):

$words = preg_replace('/[0-9]+/', '', $words);

For all numerals including Western Arabic (e.g. Indian):

$words = '????';
$words = preg_replace('/\d+/u', '', $words);
var_dump($words); // string(0) ""

• \d+ matches multiple numerals.
• The modifier /u enables unicode string treatment. This modifier is important, otherwise the numerals would not match.

A base R option is the split()-lapply()-do.call() idiom:

> do.call(rbind, lapply(split(test, test$id), head, 1))
  id string
1  1      A
2  2      B
3  3      C
4  4      D
5  5      E

A more direct option is to lapply() the [ function:

> do.call(rbind, lapply(split(test, test$id), `[`, 1, ))
  id string
1  1      A
2  2      B
3  3      C
4  4      D
5  5      E

The comma-space 1, ) at the end of the lapply() call is essential as this is equivalent of calling [1, ] to select first row and all columns.

class MathsOperations:
    def __init__ (self, x, y):
        self.a = x
        self.b = y
    def testAddition (self):
        return (self.a + self.b)

    def testMultiplication (self):
        return (self.a * self.b)

then

temp = MathsOperations()
print(temp.testAddition())

For me the issue were the multithreaded tests that were doing stubbing/verification on a shared mocks. It leaded to randomly throwing WrongTypeOfReturnValue exception.

This is not properly written test using Mockito. Mocks should not be accessed from multiple threads.

The solution was to make mocks local to each test.

There is the instagram public API's tags section that can help you do this.

My problem, it showed an error called "The class Form1 can be designed, but is not the first class in the file. Visual Studio requires that designers use the first class in the file. Move the class code so that it is the first class in the file and try loading the designer again. ". So I moved the Form class to the first one and it worked. :)

def userNum(iterations):
    myList = []
    for i in range(iterations):
        a = int(input("Enter a number for sound: "))
        myList.append(a)
    print(myList) # print before return
    return myList # return outside of loop

If you intend to read the data only from the client-side, you can use the local storage. It's deleted only when the browser's cache is cleared.

Oh, just with this:

$ docker-compose up client server database

you can define a custom ScrollView class, & add an interface be called when scrolling like this:

public class ScrollChangeListenerScrollView extends HorizontalScrollView {


private MyScrollListener mMyScrollListener;

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

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

public ScrollChangeListenerScrollView(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
}


public void setOnMyScrollListener(MyScrollListener myScrollListener){
    this.mMyScrollListener = myScrollListener;
}


@Override
protected void onScrollChanged(int l, int t, int oldl, int oldt) {
    super.onScrollChanged(l, t, oldl, oldt);
    if(mMyScrollListener!=null){
        mMyScrollListener.onScrollChange(this,l,t,oldl,oldt);
    }

}

public interface MyScrollListener {
    void onScrollChange(View view,int scrollX,int scrollY,int oldScrollX, int oldScrollY);
}

}

Database tables

To demonstrate how the USING and ON clauses work, let's assume we have the following post and post_comment database tables, which form a one-to-many table relationship via the post_id Foreign Key column in the post_comment table referencing the post_id Primary Key column in the post table:

The parent post table has 3 rows:

| post_id | title     |
|---------|-----------|
| 1       | Java      |
| 2       | Hibernate |
| 3       | JPA       |

and the post_comment child table has the 3 records:

| post_comment_id | review    | post_id |
|-----------------|-----------|---------|
| 1               | Good      | 1       |
| 2               | Excellent | 1       |
| 3               | Awesome   | 2       |

The JOIN ON clause using a custom projection

Traditionally, when writing an INNER JOIN or LEFT JOIN query, we happen to use the ON clause to define the join condition.

For example, to get the comments along with their associated post title and identifier, we can use the following SQL projection query:

SELECT
   post.post_id,
   title,
   review
FROM post
INNER JOIN post_comment ON post.post_id = post_comment.post_id
ORDER BY post.post_id, post_comment_id

And, we get back the following result set:

| post_id | title     | review    |
|---------|-----------|-----------|
| 1       | Java      | Good      |
| 1       | Java      | Excellent |
| 2       | Hibernate | Awesome   |

The JOIN USING clause using a custom projection

When the Foreign Key column and the column it references have the same name, we can use the USING clause, like in the following example:

SELECT
  post_id,
  title,
  review
FROM post
INNER JOIN post_comment USING(post_id)
ORDER BY post_id, post_comment_id

And, the result set for this particular query is identical to the previous SQL query that used the ON clause:

| post_id | title     | review    |
|---------|-----------|-----------|
| 1       | Java      | Good      |
| 1       | Java      | Excellent |
| 2       | Hibernate | Awesome   |

The USING clause works for Oracle, PostgreSQL, MySQL, and MariaDB. SQL Server doesn't support the USING clause, so you need to use the ON clause instead.

The USING clause can be used with INNER, LEFT, RIGHT, and FULL JOIN statements.

SQL JOIN ON clause with SELECT *

Now, if we change the previous ON clause query to select all columns using SELECT *:

SELECT *
FROM post
INNER JOIN post_comment ON post.post_id = post_comment.post_id
ORDER BY post.post_id, post_comment_id

We are going to get the following result set:

| post_id | title     | post_comment_id | review    | post_id |
|---------|-----------|-----------------|-----------|---------|
| 1       | Java      | 1               | Good      | 1       |
| 1       | Java      | 2               | Excellent | 1       |
| 2       | Hibernate | 3               | Awesome   | 2       |

As you can see, the post_id is duplicated because both the post and post_comment tables contain a post_id column.

SQL JOIN USING clause with SELECT *

On the other hand, if we run a SELECT * query that features the USING clause for the JOIN condition:

SELECT *
FROM post
INNER JOIN post_comment USING(post_id)
ORDER BY post_id, post_comment_id

We will get the following result set:

| post_id | title     | post_comment_id | review    |
|---------|-----------|-----------------|-----------|
| 1       | Java      | 1               | Good      |
| 1       | Java      | 2               | Excellent |
| 2       | Hibernate | 3               | Awesome   |

You can see that this time, the post_id column is deduplicated, so there is a single post_id column being included in the result set.

Conclusion

If the database schema is designed so that Foreign Key column names match the columns they reference, and the JOIN conditions only check if the Foreign Key column value is equal to the value of its mirroring column in the other table, then you can employ the USING clause.

Otherwise, if the Foreign Key column name differs from the referencing column or you want to include a more complex join condition, then you should use the ON clause instead.

It is an implementation of Pythagorean theorem. Link: http://en.wikipedia.org/wiki/Pythagorean_theorem

You need to import the map operator:

import 'rxjs/add/operator/map'

Or more generally:

import 'rxjs/Rx';

Notice: For versions of RxJS 6.x.x and above, you will have to use pipeable operators as shown in the code snippet below:

import { map } from 'rxjs/operators';
import { HttpClient } from '@angular/common/http';

// ...
export class MyComponent {
  constructor(private http: HttpClient) { }
  getItems() {
    this.http.get('https://example.com/api/items').pipe(map(data => {})).subscribe(result => {
      console.log(result);
    });
  }
}

This is caused by the RxJS team removing support for using See the breaking changes in RxJS' changelog for more info.

From the changelog:

operators: Pipeable operators must now be imported from rxjs like so: import { map, filter, switchMap } from 'rxjs/operators';. No deep imports.

You need to Open the output file for write access rather than using a new StreamReader, which always overwrites the output file.

StreamWriter stm = null;
fi = new FileInfo(@"C:\target.xml");
if (fi.Exists)
   stm = fi.OpenWrite();

Of course, you will still have to seek to the correct line in the output file, which will be hard since you can't read from it, so unless you already KNOW the byte offset to seek to, you probably really want read/write access.

FileStream stm = fi.Open(FileMode.OpenOrCreate, FileAccess.ReadWrite, FileShare.None);

with this stream, you can read until you get to the point where you want to make changes, then write. Keep in mind that you are writing bytes, not lines, so to overwrite a line you will need to write the same number of characters as the line you want to change.

The network results at Browserscope will give you both Connections per Hostname and Max Connections for popular browsers. The data is gathered by running tests on users "in the wild," so it will stay up to date.

None of these answers worked for me. I had to create my own function called alphanum which stripped the chars for me:

DROP FUNCTION IF EXISTS alphanum; 
DELIMITER | 
CREATE FUNCTION alphanum( str CHAR(255) ) RETURNS CHAR(255) DETERMINISTIC
BEGIN 
  DECLARE i, len SMALLINT DEFAULT 1; 
  DECLARE ret CHAR(255) DEFAULT ''; 
  DECLARE c CHAR(1);
  IF str IS NOT NULL THEN 
    SET len = CHAR_LENGTH( str ); 
    REPEAT 
      BEGIN 
        SET c = MID( str, i, 1 ); 
        IF c REGEXP '[[:alnum:]]' THEN 
          SET ret=CONCAT(ret,c); 
        END IF; 
        SET i = i + 1; 
      END; 
    UNTIL i > len END REPEAT; 
  ELSE
    SET ret='';
  END IF;
  RETURN ret; 
END | 
DELIMITER ; 

Now I can do:

select 'This works finally!', alphanum('This works finally!');

and I get:

+---------------------+---------------------------------+
| This works finally! | alphanum('This works finally!') |
+---------------------+---------------------------------+
| This works finally! | Thisworksfinally                |
+---------------------+---------------------------------+
1 row in set (0.00 sec)

Hurray!

In the following line.

temp.Response = db.Responses.Where(y => y.ResponseId.Equals(item.ResponseId)).First();

You are calling First but the collection returned from db.Responses.Where is empty.

It is possible to define util methods which solves this in an almost pretty way with Java 8 lambda.

This is a variation of H-MANs solution but it uses overloaded methods with multiple arguments to handle multiple steps instead of catching NullPointerException.

Even if I think this solution is kind of cool I think I prefer Helder Pereira's seconds one since that doesn't require any util methods.

void example() {
    Entry entry = new Entry();
    // This is the same as H-MANs solution 
    Person person = getNullsafe(entry, e -> e.getPerson());    
    // Get object in several steps
    String givenName = getNullsafe(entry, e -> e.getPerson(), p -> p.getName(), n -> n.getGivenName());
    // Call void methods
    doNullsafe(entry, e -> e.getPerson(), p -> p.getName(), n -> n.nameIt());        
}

/** Return result of call to f1 with o1 if it is non-null, otherwise return null. */
public static <R, T1> R getNullsafe(T1 o1, Function<T1, R> f1) {
    if (o1 != null) return f1.apply(o1);
    return null; 
}

public static <R, T0, T1> R getNullsafe(T0 o0, Function<T0, T1> f1, Function<T1, R> f2) {
    return getNullsafe(getNullsafe(o0, f1), f2);
}

public static <R, T0, T1, T2> R getNullsafe(T0 o0, Function<T0, T1> f1, Function<T1, T2> f2, Function<T2, R> f3) {
    return getNullsafe(getNullsafe(o0, f1, f2), f3);
}


/** Call consumer f1 with o1 if it is non-null, otherwise do nothing. */
public static <T1> void doNullsafe(T1 o1, Consumer<T1> f1) {
    if (o1 != null) f1.accept(o1);
}

public static <T0, T1> void doNullsafe(T0 o0, Function<T0, T1> f1, Consumer<T1> f2) {
    doNullsafe(getNullsafe(o0, f1), f2);
}

public static <T0, T1, T2> void doNullsafe(T0 o0, Function<T0, T1> f1, Function<T1, T2> f2, Consumer<T2> f3) {
    doNullsafe(getNullsafe(o0, f1, f2), f3);
}


class Entry {
    Person getPerson() { return null; }
}

class Person {
    Name getName() { return null; }
}

class Name {
    void nameIt() {}
    String getGivenName() { return null; }
}

Then there is an option that says logging floating window, you just need to disable that and you will get rid of this infernal bubble for good

You could use this to pick all li elements without class:

$('ul#list li:not([class])')

All i needed was:

.modal-header{
     background-color:#0f0;
}
.modal-content {
    overflow:hidden;
}

overflow: hidden to keep the color inside the border-radius

The whole point of a final field is that it cannot be reassigned once set. The JVM uses this guarentee to maintain consistency in various places (eg inner classes referencing outer variables). So no. Being able to do so would break the JVM!

The solution is not to declare it final in the first place.

v-bind and v-on are two frequently used directives in vuejs html template. So they provided a shorthand notation for the both of them as follows:

You can replace v-on: with @

v-on:click='someFunction'

as:

@click='someFunction'

Another example:

v-on:keyup='someKeyUpFunction'

as:

@keyup='someKeyUpFunction'

Similarly, v-bind with :

v-bind:href='var1'

Can be written as:

:href='var1'

Hope it helps!

Specify POST method in form

Have you tried the SVG text element?

.append("text").text(function(d, i) { return d[whichevernode];})

rect element doesn't permit text element inside of it. It only allows descriptive elements (<desc>, <metadata>, <title>) and animation elements (<animate>, <animatecolor>, <animatemotion>, <animatetransform>, <mpath>, <set>)

Append the text element as a sibling and work on positioning.

UPDATE

Using g grouping, how about something like this? fiddle

You can certainly move the logic to a CSS class you can append to, remove from the group (this.parentNode)

I stumbled upon a simple solution for this in Java8 (non-Android) using the ZoneDateTime class. There may be other classes that implement the TemporalAccessor interface that work, but I haven't found them. This won't work with standard Date, DateTime, LocalDateTime, and Calender classes as far as I can tell.

    ZoneOffset myOffset = ZonedDateTime.now().getOffset();
    ZoneOffset myOffset2 = ZoneOffset.from(ZonedDateTime.now());
    log.info("ZoneOffset is " + myOffset.getId());  // should print "+HH:MM"
    log.info("ZoneOffset2 is " + myOffset2.getId());  // should print "+HH:MM"

The nice thing about this solution is that it avoids a lot of modulo math, string generation, and parsing.

Using Neville's answer (deleting requireSSL = true, in web.config) and slightly modifying Joel Etherton's code, here is the code that should handle a site that runs in both SSL mode and non SSL mode, depending on the user and the page (I am jumping back into code and haven't tested it on SSL yet, but expect it should work - will be too busy later to get back to this, so here it is:

if (HttpContext.Current.Response.Cookies.Count > 0)
        {
            foreach (string s in HttpContext.Current.Response.Cookies.AllKeys)
            {
                if (s == FormsAuthentication.FormsCookieName || s.ToLower() == "asp.net_sessionid")
                {
                    HttpContext.Current.Response.Cookies[s].Secure = HttpContext.Current.Request.IsSecureConnection;
                }
            }
        }

Many ways this can be achieved.

Simple approach should be taking Substring of an input string.

var result = input.Substring(input.Length - 3);

Another approach using Regular Expression to extract last 3 characters.

var result = Regex.Match(input,@"(.{3})\s*$");

Working Demo

In my case, an aborted Nuget restore-attempt had corrupted one of the packages.configfiles in the solution. I did not discover this before checking my git working tree. After reverting the changes in the file, Nuget restore was working again.

A jar file is a zip archive. You can extract it using 7zip (a great simple tool to open archives). You can also change its extension to zip and use whatever to unzip the file.

Now you have your class file. There is no easy way to edit class file, because class files are binaries (you won't find source code in there. maybe some strings, but not java code). To edit your class file you can use a tool like classeditor.

You have all the strings your class is using hard-coded in the class file. So if the only thing you would like to change is some strings you can do it without using classeditor.

If you installed the package with the Ubuntu package manager (apt, synaptic, dpkg or similar), you can get information about the installed package with

dpkg -L <package_name>

         bool breakInnerLoop=false
        for(int i=0;i<=10;i++)
        {
          for(int J=0;i<=10;i++)
          {
              if(i<=j)
                {
                    breakInnerLoop=true;
                    break;
                }
          }
            if(breakInnerLoop)
            {
            continue
            }
        }

It is reasonable to make constructor private if there are other methods that can produce instances. Obvious examples are patterns Singleton (every call return the same instance) and Factory (every call usually create new instance).

JavaScript itself has terrible Date/Time API's. Nonetheless, you can do this in pure JavaScript:

Date.prototype.addHours = function(h) {
  this.setTime(this.getTime() + (h*60*60*1000));
  return this;
}

I noticed that Pandas for example will return 'nan' for blank values. Since it's not a string you need to convert it to one in order to match it. For example:

ulist = df.column1.unique() #create a list from a column with Pandas which 
for loc in ulist:
    loc = str(loc)   #here 'nan' is converted to a string to compare with if
    if loc != 'nan':
        print(loc)

You're thinking too complicated. It's actually just $('#'+openaddress).

Try the below code, you need not specify the schema. When you give inferSchema as true it should take it from your csv file.

val pagecount = sqlContext.read.format("csv")
  .option("delimiter"," ").option("quote","")
  .option("header", "true")
  .option("inferSchema", "true")
  .load("dbfs:/databricks-datasets/wikipedia-datasets/data-001/pagecounts/sample/pagecounts-20151124-170000")

If you want to manually specify the schema, you can do it as below:

import org.apache.spark.sql.types._

val customSchema = StructType(Array(
  StructField("project", StringType, true),
  StructField("article", StringType, true),
  StructField("requests", IntegerType, true),
  StructField("bytes_served", DoubleType, true))
)

val pagecount = sqlContext.read.format("csv")
  .option("delimiter"," ").option("quote","")
  .option("header", "true")
  .schema(customSchema)
  .load("dbfs:/databricks-datasets/wikipedia-datasets/data-001/pagecounts/sample/pagecounts-20151124-170000")

If the image is in a container with a responsive width:

HTML

<div class="img-container">
  <img src="" alt="">
</div>

CSS

.img-container {
  position: relative;

  &::after {
    content: "";
    display: block;
    padding-bottom: 100%;
  }

  img {
    position: absolute;
    width: 100%;
    height: 100%;
    object-fit: cover;
  }
}

This may help:

public string NonBlankValueOf(string strTestString)
{
    return String.IsNullOrEmpty(strTestString)? "0": strTestString;
}

Actually correct one to one implementation is:

int n;
int[] ia = s1.Split(';').Select(s => int.TryParse(s, out n) ? n : 0).ToArray();

Agree with Rishikesh. I too tried to solve this issue for a long time. This will be solved with either or both of 2 methods-

1.Try deleting the migrations in the app's migrations folder(except init.py) and then running makemigrations command

2.If that doesn't work, try renaming the model (this is the last resort and might get a little messy but will work for sure.If django asks "did you rename the model? just press N.").Hope it helps..:)

you can use the skip() function to skip the lines from begining.

public static void readFile(String filePath, long lineNum) {
    List<String> list = new ArrayList<>();
    long totalLines, startLine = 0;

    try (Stream<String> lines = Files.lines(Paths.get(filePath))) {
        totalLines = Files.lines(Paths.get(filePath)).count();
        startLine = totalLines - lineNum;
        // Stream<String> line32 = lines.skip(((startLine)+1));

        list = lines.skip(startLine).collect(Collectors.toList());
        // lines.forEach(list::add);
    } catch (IOException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }

    list.forEach(System.out::println);

}

None of the answers here solved my issue (as at February 2020), so I raised an issue at https://issues.apache.org/jira/browse/NETBEANS-3903 and Netbeans fixed the issue!

They're working on a pull request so the fix will be in a future .dmg installer soon, but in the meantime you can copy a file referenced in the bug and replace one in your netbeans modules folder.

Tip - if you right click on Applications > Netbeans and choose Show Package Contents then you can find and replace the file org-netbeans-modules-tomcat5.jar that they refer to in your Netbeans folder, e.g. within /Applications/NetBeans/Apache NetBeans 11.2.app/Contents/Resources/NetBeans/netbeans/enterprise/modules

By default, when you click on the button, the form would be sent to server no matter what value you have input.

However, this behavior is not quite appropriate for most cases because we may want to do some checking before sending it to server.

So, when the listener received "false", the submitting would be cancelled. Basically, it is for the purpose to do some checking on front end.

If you want to remove an item, the following will be a bit more efficient.

std::vector<int> v;


auto it = std::find(v.begin(), v.end(), 5);
if(it != v.end())
    v.erase(it);

or you may avoid overhead of moving the items if the order does not matter to you:

std::vector<int> v;

auto it = std::find(v.begin(), v.end(), 5);

if (it != v.end()) {
  using std::swap;

  // swap the one to be removed with the last element
  // and remove the item at the end of the container
  // to prevent moving all items after '5' by one
  swap(*it, v.back());
  v.pop_back();
}

Let's measure the performance by using the following piece of code.

import numpy as np
import time

exec_time0 = []
exec_time1 = []
exec_time2 = []

sizeOfArray = 5000
numOfIterations = 200

for i in xrange(numOfIterations):

    A = np.random.randint(0,255,(sizeOfArray,sizeOfArray))
    B = np.random.randint(0,255,(sizeOfArray,sizeOfArray))

    a = time.clock() 
    res = (A==B).all()
    b = time.clock()
    exec_time0.append( b - a )

    a = time.clock() 
    res = np.array_equal(A,B)
    b = time.clock()
    exec_time1.append( b - a )

    a = time.clock() 
    res = np.array_equiv(A,B)
    b = time.clock()
    exec_time2.append( b - a )

print 'Method: (A==B).all(),       ', np.mean(exec_time0)
print 'Method: np.array_equal(A,B),', np.mean(exec_time1)
print 'Method: np.array_equiv(A,B),', np.mean(exec_time2)

Output

Method: (A==B).all(),        0.03031857
Method: np.array_equal(A,B), 0.030025185
Method: np.array_equiv(A,B), 0.030141515

According to the results above, the numpy methods seem to be faster than the combination of the == operator and the all() method and by comparing the numpy methods the fastest one seems to be the numpy.array_equal method.

There is no way to do this in single query. You have to search the document in first query:

If document exists:

db.bar.update( {user_id : 123456 , "items.item_name" : "my_item_two" } , 
                {$inc : {"items.$.price" : 1} } , 
                false , 
                true);

Else

db.bar.update( {user_id : 123456 } , 
                {$addToSet : {"items" : {'item_name' : "my_item_two" , 'price' : 1 }} } ,
                false , 
                true);

No need to add condition {$ne : "my_item_two" }.

Also in multithreaded enviourment you have to be careful that only one thread can execute the second (insert case, if document did not found) at a time, otherwise duplicate embed documents will be inserted.

You don't need custom directive here. Just use ng-include src attribute. It's compiled so you can put code inside. See plunker with solution for your issue.

<div ng-repeat="week in [1,2]">
  <div ng-repeat="day in ['monday', 'tuesday']">
    <ng-include src="'content/before-'+ week + '-' + day + '.html'"></ng-include>
  </div>
</div>

I was working also on web scraping project and same issue found, below code applied and it worked nicely. If you are not aware about TLS versions then you can apply all below otherwise you can apply specific.

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11;

In my case eclipse is not showing parent class function on $this, so I perform below mention points and it starts works:-

I go to my /var/www/ folder and check for .metadata folder (Here check the .log file and it shows) Resource is out of sync with the file system: 1. Go to Eclipse --> Project --> Clean 2. Windows -- preferences --> General --> Workspace --> And set it to "Refresh Automatically"

After that boom - things gets start working :)

If you want to load variables from other files too then ado this :- Eclipse-->Windows-->Preferences-->Php-->Editor-->Content Assist --> and check "show variable from other files"

Then it will show element , variables and other functions also.

You can Try this ,

Here you can get the date based on the Client Timezone (Browser).

moment(new Date().getTime()).zone(new Date().toString().match(/([-\+][0-9]+)\s/)[1]).format('YYYY-MM-DD HH:mm:ss')

The regex basically gets you the offset value.

Cheers!!

if you're not using the -> format, you can do this:

$a = "SQL command...";
if ($b = mysqli_query($con,$a)) {
  // results was successful
} else {
  // result was not successful
}

Model View Controller (MVC)

Description:

• When we have to main large projects in the software development, MVC is generally used because it’s a universal way of organizing the projects.
• New developers can quickly adapt to the project
• Helps in development of big projects and cross platform too.

The MVC pattern is essentially this:

• Model: What to display. This can be the data source (Ex: Server, Raw data in the app)
• View: How it’s displayed. This can be the xml. It is thus acting as a presentation filter. A view is attached to its model (or model part) and gets the data necessary for the presentation.
• Controller: Handling events like user input. This be the activity

Important feature of MVC: We can modify Either the Model or View or Controller still not affecting the other ones

• Say we change the color in the view, size of the view or the position of the view. By doing so it won’t affect the model or the controller
• Say we change the model (instead of data fetched from the server fetch data from assets ) still it won’t affect the view and controller
• Say we change the Controller(Logic in the activity) it won’t affect the model and the view

It is possible and is deceptively easy:

1. "Publish" the application (to, say, some folder on drive C), either from menu Build or from the project's properties ? Publish. This will create an installer for a ClickOnce application.
2. But instead of using the produced installer, find the produced files (the EXE file and the .config, .manifest, and .application files, along with any DLL files, etc.) - they are all in the same folder and typically in the bin\Debug folder below the project file (.csproj).
3. Zip that folder (leave out any *.vhost.* files and the app.publish folder (they are not needed), and the .pdb files unless you foresee debugging directly on your user's system (for example, by remote control)), and provide it to the users.

An added advantage is that, as a ClickOnce application, it does not require administrative privileges to run (if your application follows the normal guidelines for which folders to use for application data, etc.).

As for .NET, you can check for the minimum required version of .NET being installed (or at all) in the application (most users will already have it installed) and present a dialog with a link to the download page on the Microsoft website (or point to one of your pages that could redirect to the Microsoft page - this makes it more robust if the Microsoft URL change). As it is a small utility, you could target .NET 2.0 to reduce the probability of a user to have to install .NET.

It works. We use this method during development and test to avoid having to constantly uninstall and install the application and still being quite close to how the final application will run.

Just add

model.addAttribute("login", new Login());

to your method ..

it will work..

Any line starting with a "REM" is treated as a comment, nothing is executed including the redirection.

Also, the %date% variable may contain "/" characters which are treated as path separator characters, leading to the system being unable to create the desired log file.

As a reflex answer, I would recommend using rem, because it allows you to change the "zoom level" of the whole document at once, if necessary. In some cases, when you want the size to be relative to the parent element, then use em.

But rem support is spotty, IE8 needs a polyfill, and Webkit is exhibiting a bug. Moreover, sub-pixel calculation can cause things such as one pixel lines to sometimes disappear. The remedy is to code in pixels for such very small elements. That introduces even more complexity.

So, overall, ask yourself whether it's worth it - how important and likely it is that you change the "zoom level" of the whole document within CSS?

For some cases it's yes, for some cases it'll be no.

So, it depends on your needs, and you have to weight pros and cons, because using rem and em introduces some additional considerations in comparison to the "normal" pixel-based workflow.

Keep in mind that it's easy to switch (or rather convert) your CSS from px to rem (JavaScript is another story), because the following two blocks of CSS code would produce the same result:

html {
}

body {
  font-size:14px;
}

.someElement {
  width: 12px;
}

html {
  font-size:1px;
}

body {
  font-size:14rem;
}

.someElement {
  width: 12rem;
}

Clearly there are lots of different ways of getting the same results, your question seems to be what is an efficient way of getting the last results in each group in MySQL. If you are working with huge amounts of data and assuming you are using InnoDB with even the latest versions of MySQL (such as 5.7.21 and 8.0.4-rc) then there might not be an efficient way of doing this.

We sometimes need to do this with tables with even more than 60 million rows.

For these examples I will use data with only about 1.5 million rows where the queries would need to find results for all groups in the data. In our actual cases we would often need to return back data from about 2,000 groups (which hypothetically would not require examining very much of the data).

I will use the following tables:

CREATE TABLE temperature(
  id INT UNSIGNED NOT NULL AUTO_INCREMENT, 
  groupID INT UNSIGNED NOT NULL, 
  recordedTimestamp TIMESTAMP NOT NULL, 
  recordedValue INT NOT NULL,
  INDEX groupIndex(groupID, recordedTimestamp), 
  PRIMARY KEY (id)
);

CREATE TEMPORARY TABLE selected_group(id INT UNSIGNED NOT NULL, PRIMARY KEY(id)); 

The temperature table is populated with about 1.5 million random records, and with 100 different groups. The selected_group is populated with those 100 groups (in our cases this would normally be less than 20% for all of the groups).

As this data is random it means that multiple rows can have the same recordedTimestamps. What we want is to get a list of all of the selected groups in order of groupID with the last recordedTimestamp for each group, and if the same group has more than one matching row like that then the last matching id of those rows.

If hypothetically MySQL had a last() function which returned values from the last row in a special ORDER BY clause then we could simply do:

SELECT 
  last(t1.id) AS id, 
  t1.groupID, 
  last(t1.recordedTimestamp) AS recordedTimestamp, 
  last(t1.recordedValue) AS recordedValue
FROM selected_group g
INNER JOIN temperature t1 ON t1.groupID = g.id
ORDER BY t1.recordedTimestamp, t1.id
GROUP BY t1.groupID;

which would only need to examine a few 100 rows in this case as it doesn't use any of the normal GROUP BY functions. This would execute in 0 seconds and hence be highly efficient. Note that normally in MySQL we would see an ORDER BY clause following the GROUP BY clause however this ORDER BY clause is used to determine the ORDER for the last() function, if it was after the GROUP BY then it would be ordering the GROUPS. If no GROUP BY clause is present then the last values will be the same in all of the returned rows.

However MySQL does not have this so let's look at different ideas of what it does have and prove that none of these are efficient.

Example 1

SELECT t1.id, t1.groupID, t1.recordedTimestamp, t1.recordedValue
FROM selected_group g
INNER JOIN temperature t1 ON t1.id = (
  SELECT t2.id
  FROM temperature t2 
  WHERE t2.groupID = g.id
  ORDER BY t2.recordedTimestamp DESC, t2.id DESC
  LIMIT 1
);

This examined 3,009,254 rows and took ~0.859 seconds on 5.7.21 and slightly longer on 8.0.4-rc

Example 2

SELECT t1.id, t1.groupID, t1.recordedTimestamp, t1.recordedValue 
FROM temperature t1
INNER JOIN ( 
  SELECT max(t2.id) AS id   
  FROM temperature t2
  INNER JOIN (
    SELECT t3.groupID, max(t3.recordedTimestamp) AS recordedTimestamp
    FROM selected_group g
    INNER JOIN temperature t3 ON t3.groupID = g.id
    GROUP BY t3.groupID
  ) t4 ON t4.groupID = t2.groupID AND t4.recordedTimestamp = t2.recordedTimestamp
  GROUP BY t2.groupID
) t5 ON t5.id = t1.id;

This examined 1,505,331 rows and took ~1.25 seconds on 5.7.21 and slightly longer on 8.0.4-rc

Example 3

SELECT t1.id, t1.groupID, t1.recordedTimestamp, t1.recordedValue 
FROM temperature t1
WHERE t1.id IN ( 
  SELECT max(t2.id) AS id   
  FROM temperature t2
  INNER JOIN (
    SELECT t3.groupID, max(t3.recordedTimestamp) AS recordedTimestamp
    FROM selected_group g
    INNER JOIN temperature t3 ON t3.groupID = g.id
    GROUP BY t3.groupID
  ) t4 ON t4.groupID = t2.groupID AND t4.recordedTimestamp = t2.recordedTimestamp
  GROUP BY t2.groupID
)
ORDER BY t1.groupID;

This examined 3,009,685 rows and took ~1.95 seconds on 5.7.21 and slightly longer on 8.0.4-rc

Example 4

SELECT t1.id, t1.groupID, t1.recordedTimestamp, t1.recordedValue
FROM selected_group g
INNER JOIN temperature t1 ON t1.id = (
  SELECT max(t2.id)
  FROM temperature t2 
  WHERE t2.groupID = g.id AND t2.recordedTimestamp = (
      SELECT max(t3.recordedTimestamp)
      FROM temperature t3 
      WHERE t3.groupID = g.id
    )
);

This examined 6,137,810 rows and took ~2.2 seconds on 5.7.21 and slightly longer on 8.0.4-rc

Example 5

SELECT t1.id, t1.groupID, t1.recordedTimestamp, t1.recordedValue
FROM (
  SELECT 
    t2.id, 
    t2.groupID, 
    t2.recordedTimestamp, 
    t2.recordedValue, 
    row_number() OVER (
      PARTITION BY t2.groupID ORDER BY t2.recordedTimestamp DESC, t2.id DESC
    ) AS rowNumber
  FROM selected_group g 
  INNER JOIN temperature t2 ON t2.groupID = g.id
) t1 WHERE t1.rowNumber = 1;

This examined 6,017,808 rows and took ~4.2 seconds on 8.0.4-rc

Example 6

SELECT t1.id, t1.groupID, t1.recordedTimestamp, t1.recordedValue 
FROM (
  SELECT 
    last_value(t2.id) OVER w AS id, 
    t2.groupID, 
    last_value(t2.recordedTimestamp) OVER w AS recordedTimestamp, 
    last_value(t2.recordedValue) OVER w AS recordedValue
  FROM selected_group g
  INNER JOIN temperature t2 ON t2.groupID = g.id
  WINDOW w AS (
    PARTITION BY t2.groupID 
    ORDER BY t2.recordedTimestamp, t2.id 
    RANGE BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING
  )
) t1
GROUP BY t1.groupID;

This examined 6,017,908 rows and took ~17.5 seconds on 8.0.4-rc

Example 7

SELECT t1.id, t1.groupID, t1.recordedTimestamp, t1.recordedValue 
FROM selected_group g
INNER JOIN temperature t1 ON t1.groupID = g.id
LEFT JOIN temperature t2 
  ON t2.groupID = g.id 
  AND (
    t2.recordedTimestamp > t1.recordedTimestamp 
    OR (t2.recordedTimestamp = t1.recordedTimestamp AND t2.id > t1.id)
  )
WHERE t2.id IS NULL
ORDER BY t1.groupID;

This one was taking forever so I had to kill it.

If you don't mind using a third party library, with cyclops-react, a library I contribute to, you can use the FluentFunctions API to write

 Function<String, Integer> standardFn = FluentFunctions.ofChecked(this::myMethod);

ofChecked takes a jOO? CheckedFunction and returns the reference softened back to a standard (unchecked) JDK java.util.function.Function.

Alternatively you can keep working with the captured function via the FluentFunctions api!

For example to execute your method, retrying it up to 5 times and logging it's status you can write

  FluentFunctions.ofChecked(this::myMethod)
                 .log(s->log.debug(s),e->log.error(e,e.getMessage())
                 .try(5,1000)
                 .apply("my param");

I had the same problem, i solved it by:
1 - i uninstall virtual box
2 - i uninstall genymotion with all new folder that dependency
3 - download latest version of virtual box(from oracle site)
4 - download latest version of Genymotion(without virtual box version
size:about42M)
5 - first install virtual box
6 - install genymotion
7 - before run genymotion you should restart your windows os
8 - run genymotion as admin
Sorry for my english writing
I'm new to learn :D

JConsole has a graphical view.

You also have VisualVM and Oracle JRockit Mission Control

The extensions available for each version of Postgresql vary. An easy way to check which extensions are available is, as has been already mentioned:

SELECT * FROM pg_available_extensions;

If the extension that you are looking for is available, you can install it using:

CREATE EXTENSION 'extensionName';

or if you want to drop it use:

DROP EXTENSION 'extensionName';

With psql you can additionally check if the extension has been successfully installed using \dx, and find more details about the extension using \dx+ extensioName. It returns additional information about the extension, like which packages are used with it.

If the extension is not available in your Postgres version, then you need to download the necessary binary files and libraries and locate it them at /usr/share/conrib

By definition dictionaries are unordered, and therefore cannot be indexed. For that kind of functionality use an ordered dictionary. Python Ordered Dictionary

Not sure if that's exactly what are you looking for, but I did single/double taps without gesture recognizers. I'm using it in a UITableView, so I used that code in the didSelectRowAtIndexPath method

    tapCount++;
    switch (tapCount)
    {
        case 1: //single tap
            [self performSelector:@selector(singleTap:) withObject: indexPath afterDelay: 0.2];
            break;
        case 2: //double tap
            [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(singleTap:) object:indexPath];
            [self performSelector:@selector(doubleTap:) withObject: indexPath];
            break;
        default:
            break;
    }
    if (tapCount>2) tapCount=0;

Methods singleTap and doubleTap are just void with NSIndexPath as a parameter:

- (void)singleTap:(NSIndexPath *)indexPath {
  //do your stuff for a single tap
}

- (void)doubleTap:(NSIndexPath *)indexPath {
  //do your stuff for a double tap
}

Hope it helps

As others have said, the minumum/maximum values the column can store and how much storage it takes in bytes is only defined by the type, not the length.

A lot of these answers are saying that the (11) part only affects the display width which isn't exactly true, but mostly.

A definition of int(2) with no zerofill specified will:

• still accept a value of 100
• still display a value of 100 when output (not 0 or 00)
• the display width will be the width of the largest value being output from the select query.

The only thing the (2) will do is if zerofill is also specified:

• a value of 1 will be shown 01.
• When displaying values, the column will always have a width of the maximum possible value the column could take which is 10 digits for an integer, instead of the miniumum width required to display the largest value that column needs to show for in that specific select query, which could be much smaller.
• The column can still take, and show a value exceeding the length, but these values will not be prefixed with 0s.

The best way to see all the nuances is to run:

CREATE TABLE `mytable` (
    `id` int(11) NOT NULL AUTO_INCREMENT,
    `int1` int(10) NOT NULL,
    `int2` int(3) NOT NULL,
    `zf1` int(10) ZEROFILL NOT NULL,
    `zf2` int(3) ZEROFILL NOT NULL,
    PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

INSERT INTO `mytable` 
(`int1`, `int2`, `zf1`, `zf2`) 
VALUES
(10000, 10000, 10000, 10000),
(100, 100, 100, 100);

select * from mytable;

which will output:

+----+-------+-------+------------+-------+
| id | int1  | int2  | zf1        | zf2   |
+----+-------+-------+------------+-------+
|  1 | 10000 | 10000 | 0000010000 | 10000 |
|  2 |   100 |   100 | 0000000100 |   100 |

This answer is tested against MySQL 5.7.12 for Linux and may or may not vary for other implementations.

Alternatively, you can bring variables in from the outside scope by using closures with the use keyword.

$myVar = "foo";
$myFunction = function($arg1, $arg2) use ($myVar)
{
 return $arg1 . $myVar . $arg2;
};
