I would recommend the use of IPNetwork Library https://github.com/lduchosal/ipnetwork. As of version 2, it supports IPv4 and IPv6 as well.

IPv4

  IPNetwork ipnetwork = IPNetwork.Parse("192.168.0.1/25");

  Console.WriteLine("Network : {0}", ipnetwork.Network);
  Console.WriteLine("Netmask : {0}", ipnetwork.Netmask);
  Console.WriteLine("Broadcast : {0}", ipnetwork.Broadcast);
  Console.WriteLine("FirstUsable : {0}", ipnetwork.FirstUsable);
  Console.WriteLine("LastUsable : {0}", ipnetwork.LastUsable);
  Console.WriteLine("Usable : {0}", ipnetwork.Usable);
  Console.WriteLine("Cidr : {0}", ipnetwork.Cidr);

Output

  Network : 192.168.0.0
  Netmask : 255.255.255.128
  Broadcast : 192.168.0.127
  FirstUsable : 192.168.0.1
  LastUsable : 192.168.0.126
  Usable : 126
  Cidr : 25

Have fun !

The better and correct solution is to have a directive. The scope is the same, whether in the controller of the directive or the main controller. Use $element to do DOM operations. The method defined in the directive controller is accessible in the main controller.

Example, finding a child element:

var app = angular.module('myapp', []);
app.directive("testDir", function () {
    function link(scope, element) { 

    }
    return {
        restrict: "AE", 
        link: link, 
        controller:function($scope,$element){
            $scope.name2 = 'this is second name';
            var barGridSection = $element.find('#barGridSection'); //helps to find the child element.
    }
    };
})

app.controller('mainController', function ($scope) {
$scope.name='this is first name'
});

When it is on server side, use web services - maybe RESTful with JSON.

• create a web service (for example with Tomcat)
• call its URL from JavaScript (for example with JQuery or dojo)

When Java code is in applet you can use JavaScript bridge. The bridge between the Java and JavaScript programming languages, known informally as LiveConnect, is implemented in Java plugin. Formerly Mozilla-specific LiveConnect functionality, such as the ability to call static Java methods, instantiate new Java objects and reference third-party packages from JavaScript, is now available in all browsers.

Below is example from documentation. Look at methodReturningString.

Java code:

public class MethodInvocation extends Applet {
    public void noArgMethod() { ... }
    public void someMethod(String arg) { ... }
    public void someMethod(int arg) { ... }
    public int  methodReturningInt() { return 5; }
    public String methodReturningString() { return "Hello"; }
    public OtherClass methodReturningObject() { return new OtherClass(); }
}

public class OtherClass {
    public void anotherMethod();
}

Web page and JavaScript code:

<applet id="app"
        archive="examples.jar"
        code="MethodInvocation" ...>
</applet>
<script language="javascript">
    app.noArgMethod();
    app.someMethod("Hello");
    app.someMethod(5);
    var five = app.methodReturningInt();
    var hello = app.methodReturningString();
    app.methodReturningObject().anotherMethod();
</script>

Just iterate over the transposed of your array:

for column in array.T:
   some_function(column)

Another approach:

declaring an int first with the default fontsize

int txtSize = 16;

           button.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    mTextView.setTextSize(txtSize++);
                }
            });

Single method for Reactive Forms

TYPESCRIPT

// All is this method
onPasswordChange() {
  if (this.confirm_password.value == this.password.value) {
    this.confirm_password.setErrors(null);
  } else {
    this.confirm_password.setErrors({ mismatch: true });
  }
}

// getting the form control elements
get password(): AbstractControl {
  return this.form.controls['password'];
}

get confirm_password(): AbstractControl {
  return this.form.controls['confirm_password'];
}

HTML

// PASSWORD FIELD
<input type="password" formControlName="password" />

// CONFIRM PASSWORD FIELD
<input type="password" formControlName="confirm_password" (change)="onPasswordChange()" />

// SHOW ERROR IF MISMATCH
<span *ngIf="confirm_password.hasError('mismatch')">Password do not match.</span>

On the replacement side, you must use $1, not \1.

And you can only do what you want by making replace an evalable expression that gives the result you want and telling s/// to eval it with the /ee modifier like so:

$find="start (.*) end";
$replace='"foo $1 bar"';

$var = "start middle end";
$var =~ s/$find/$replace/ee;

print "var: $var\n";

To see why the "" and double /e are needed, see the effect of the double eval here:

$ perl
$foo = "middle";
$replace='"foo $foo bar"';
print eval('$replace'), "\n";
print eval(eval('$replace')), "\n";
__END__
"foo $foo bar"
foo middle bar

(Though as ikegami notes, a single /e or the first /e of a double e isn't really an eval(); rather, it tells the compiler that the substitution is code to compile, not a string. Nonetheless, eval(eval(...)) still demonstrates why you need to do what you need to do to get /ee to work as desired.)

Use below syntax to create schema class from XSD file.

C:\xsd C:\Test\test-Schema.xsd /classes /language:cs /out:C:\Test\

<htmltag id=’elementId’ data-ZZZZ’=’@Html.Raw(Json.Encode(Model))’ />

Refer https://highspeedlowdrag.wordpress.com/2014/08/23/mvc-data-to-jquery-data/

I did below and it works like charm.

<input id="hdnElement" class="hdnElement" type="hidden" value='@Html.Raw(Json.Encode(Model))'>

The following command could help you to filter the lines which include the substring "foo".

cat file | grep -v "foo"

For Remove outline for anchor tag

a {outline : none;}

Remove outline from image link

a img {outline : none;}

Remove border from image link

img {border : 0;}

You can use import data with wizard and there you can choose destination table.

Run the wizard. In selecting source tables and views window you see two parts. Source and Destination.

Click on the field under Destination part to open the drop down and select you destination table and edit its mappings if needed.

EDIT

Merely typing the name of the table does not work. It appears that the name of the table must include the schema (dbo) and possibly brackets. Note the dropdown on the right hand side of the text field.

For preventing naming conflicts, only import the variables that you need:

variableInFile () {
    variable="${1}"
    file="${2}"

    echo $(
        source "${file}";
        eval echo \$\{${variable}\}
    )
}

$sort = array();
$array_lowercase = array_map('strtolower', $array_to_be_sorted);
array_multisort($array_lowercase, SORT_ASC, SORT_STRING, $alphabetically_ordered_array);

This takes care of both upper and lower case alphabets.

Or use this:

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
            android:scrollbars="vertical" 
            android:layout_height="wrap_content" 
            android:layout_width="fill_parent">

  <LinearLayout android:orientation="vertical"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent">

     <!-- Add your UI elements inside the inner most linear layout -->

  </LinearLayout>
</ScrollView>

I don't see php file, but that could be that -
replace in your php file:

$query_age = $_GET['query_age'];

with:

$query_age = (isset($_GET['query_age']) ? $_GET['query_age'] : null);

Most probably, at first time you running your script without ?query_age=[something] and $_GET has no key like query_age.

This works much easier for me.

public class RepeatTests extends TestCase {

    public static Test suite() {
        TestSuite suite = new TestSuite(RepeatTests.class.getName());

        for (int i = 0; i < 10; i++) {              
        suite.addTestSuite(YourTest.class);             
        }

        return suite;
    }
}

My solution to fix that problem was the following:

Start > search > cmd.exe (Run as administrator)

Inside the Command Prompt (cmd.exe) type:

cd c:/wamp/bin/apache/ApacheX.X.X/bin
httpd.exe -e debug

**Note that the ApacheX.X.X is the version of the Apache wamp is running.

This should output what the apache server is doing. The error that causes Apache from loading should be in there. My problem was that httpd.conf was trying to load a DLL that was missing or was corrupted (php5apache2_4.dll). As soon as I overwrote this file, I restarted Wamp and everything ran smooth.

I found it on this page: http://eslint.org/docs/user-guide/configuring

In package.json, this works:

"eslintConfig": {
  "globals": {
    "window": true
  }
}

See this link for our own Implementation of NamespaceContext

Here is how you do it in Swift 3:

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    if indexPath.row == 0 {
        // perform your logic here, for the first row in the table
    }

    // ....
}

The user-agent should be specified as a field in the header.

Here is a list of HTTP header fields, and you'd probably be interested in request-specific fields, which includes User-Agent.

If you're using requests v2.13 and newer

The simplest way to do what you want is to create a dictionary and specify your headers directly, like so:

import requests

url = 'SOME URL'

headers = {
    'User-Agent': 'My User Agent 1.0',
    'From': '[email protected]'  # This is another valid field
}

response = requests.get(url, headers=headers)

If you're using requests v2.12.x and older

Older versions of requests clobbered default headers, so you'd want to do the following to preserve default headers and then add your own to them.

import requests

url = 'SOME URL'

# Get a copy of the default headers that requests would use
headers = requests.utils.default_headers()

# Update the headers with your custom ones
# You don't have to worry about case-sensitivity with
# the dictionary keys, because default_headers uses a custom
# CaseInsensitiveDict implementation within requests' source code.
headers.update(
    {
        'User-Agent': 'My User Agent 1.0',
    }
)

response = requests.get(url, headers=headers)

{
    height:100vh;
    width:100vw;
}

Well, i also made a piece of code for limit high frequency ajax request cause by Keyup / Keydown. Check this out:

https://github.com/raincious/jQueue

Do your query like this:

var q = new jQueue(function(type, name, callback) {
    return $.post("/api/account/user_existed/", {Method: type, Value: name}).done(callback);
}, 'Flush', 1500); // Make sure use Flush mode.

And bind event like this:

$('#field-username').keyup(function() {
    q.run('Username', this.val(), function() { /* calling back */ });
});

Have you tried this?

$(document).ajaxError(function(){ alert('error'); }

That should handle all AjaxErrors. I´ve found it here. There you find also a possibility to write these errors to your firebug console.

You can update your python version to 3.8 in conda using the command

conda install -c anaconda python=3.8

as per https://anaconda.org/anaconda/python. Though not all packages support 3.8 yet, running

conda update --all

may resolve some dependency failures. You can also create a new environment called py38 using this command

conda create -n py38 python=3.8

Edit - note that the conda install option will potentially take a while to solve the environment, and if you try to abort this midway through you will lose your Python installation (usually this means it will resort to non-conda pre-installed system Python installation).

your dependency based on data is trying to find their respective entities which one has not been created, comments the dependencies based on data and runs the app again.

<!-- <dependency> -->
        <!-- <groupId>org.springframework.boot</groupId> -->
        <!-- <artifactId>spring-boot-starter-data-jpa</artifactId> -->
        <!-- </dependency> -->

See if you have a file located under /etc/my.cnf. If so, it should tell you where the data directory is.

For example:

[mysqld]
set-variable=local-infile=0
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
...

My guess is that your mysql might be installed to /usr/local/mysql-XXX.

You may find these MySQL reference manual links useful:

• Installing MySQL 8.0 on MacOS
• Installing MySQL 5.7 on MacOS
• Installing MySQL 5.6 on MacOS
• Installing MySQL 5.5 on MacOS

Furthermore, as said in file_put_contents man page in php.net, beware of naming issues.

file_put_contents($dir."/file.txt", "hello");

may not work (even though it is correct on syntax), but

file_put_contents("$dir/file.txt", "hello");

works. I experienced this on different php installed servers.

This has to go in the category of "world's ugliest hacks", but here you go.

First up, printing the name of the current function (as in the other answers) seems to have limited use to me, since you kind of already know what the function is!

However, finding out the name of the calling function could be pretty useful for a trace function. This is with a regexp, but using indexOf would be about 3x faster:

function getFunctionName() {
    var re = /function (.*?)\(/
    var s = getFunctionName.caller.toString();
    var m = re.exec( s )
    return m[1];
}

function me() {
    console.log( getFunctionName() );
}

me();

You need the Clear() function on the list, like so.

List<object> myList = new List<object>();

myList.Add(new object()); // Add something to the list

myList.Clear() // Our list is now empty

With PostgreSQL you can do it via the RETURNING keyword:

PostgresSQL - RETURNING

INSERT INTO mytable( field_1, field_2,... )
VALUES ( value_1, value_2 ) RETURNING anyfield

It will return the value of "anyfield". "anyfield" may be a sequence or not.

To use it with JDBC, do:

ResultSet rs = statement.executeQuery("INSERT ... RETURNING ID");
rs.next();
rs.getInt(1);

To get rid of error:

Type '"text"' is not assignable to type '"json"'.

Use

responseType: 'text' as 'json'

import { HttpClient, HttpHeaders } from '@angular/common/http';
.....
 return this.http
        .post<string>(
            this.baseUrl + '/Tickets/getTicket',
            JSON.stringify(value),
        { headers, responseType: 'text' as 'json' }
        )
        .map(res => {
            return res;
        })
        .catch(this.handleError);

Converting to double can be done by casting an int to a double:

You can convert an int to a double by using this mechnism like so:

int i = 3; // i is 3
double d = (double) i; // d = 3.0

Alternative (using Java's automatic type recognition):

double d = 1.0 * i; // d = 3.0

Implementing this in your code would be something like:

double firstSolution = ((double)(b1 * a22 - b2 * a12) / (double)(a11 * a22 - a12 * a21));
double secondSolution = ((double)(b2 * a11 - b1 * a21) / (double)(a11 * a22 - a12 * a21));

Alternatively you can use a hard-parameter of type double (1.0) to have java to the work for you, like so:

double firstSolution = ((1.0 * (b1 * a22 - b2 * a12)) / (1.0 * (a11 * a22 - a12 * a21)));
double secondSolution = ((1.0 * (b2 * a11 - b1 * a21)) / (1.0 * (a11 * a22 - a12 * a21)));

Good luck.

I would not use KML. Instead, use GeoJSON which you can natively consume in Google Maps API now. It is a newer feature that didn't exist from the original responses.

In any case, simply open the SHP file in Quantum GIS, and then you can output it in any format you like (KML, GeoJSON).

If you are using Google Maps for Work, I found a premium extension that handles loading shapefiles directly where you can just connect direct to the shapefile that you generate from ESRI. I did a search on the CMaps site and found this snippet which loaded US by state shapefile: https://gmapsplugin.net/cmapsanalytics/assets/shapes/usstates.shp

MemoryStream ms = new MemoryStream();    
FileStream file = new FileStream("file.bin", FileMode.Create, FileAccess.Write);
ms.WriteTo(file);
file.Close();
ms.Close();

In your example, the second return will never happen - the first return is the last thing PHP will run. If you need to return multiple values, return an array:

function test($testvar) {

    return array($var1, $var2);
}

$result = test($testvar);
echo $result[0]; // $var1
echo $result[1]; // $var2

you can set your logging configuration file through command line:

$ java -Djava.util.logging.config.file=/path/to/app.properties MainClass

this way seems cleaner and easier to maintain.

Not sure if it will work for all versions of Android (especially those with custom UI stuff), but I was able to remove the gray bar at the bottom by adding

 android:layout_marginBottom="-3dp"

to the TabWidget XML...

If the table is already created in the database, then you can add a unique constraint later on by using this SQL query:

ALTER TABLE dbo.User
  ADD CONSTRAINT ucCodes UNIQUE (fcode, scode, dcode)

--launcher.XXMaxPermSize

256m

Try to bump that value up!

A small variation but nothing new infact. It's really missing a feature...

select info->>'name' from rabbits 
where '"carrots"' = ANY (ARRAY(
    select * from json_array_elements(info->'food'))::text[]);

From application perspective, if one needs only to avoid duplicates then HashSet is what you are looking for since it's Lookup, Insert and Remove complexities are O(1) - constant. What this means it does not matter how many elements HashSet has it will take same amount of time to check if there's such element or not, plus since you are inserting elements at O(1) too it makes it perfect for this sort of thing.

PHP is evaluated at the server; javascript is evaluated at the client/browser, thus you can't call a PHP function from javascript directly. But you can issue an HTTP request to the server that will activate a PHP function, with AJAX.

Can this not be done with a user-defined function to replicate whatever your stored procedure is doing?

SELECT udfMyFunction(user_id), someOtherField, etc FROM MyTable WHERE WhateverCondition

where udfMyFunction is a function you make that takes in the user ID and does whatever you need to do with it.

See http://www.sqlteam.com/article/user-defined-functions for a bit more background

I agree that cursors really ought to be avoided where possible. And it usually is possible!

(of course, my answer presupposes that you're only interested in getting the output from the SP and that you're not changing the actual data. I find "alters user data in a certain way" a little ambiguous from the original question, so thought I'd offer this as a possible solution. Utterly depends on what you're doing!)

From the docs

IF boolean-expression THEN
    statements
ELSE
    statements
END IF;

So in your above example the code should look as follows:

IF select count(*) from orders > 0
THEN
  DELETE from orders
ELSE 
  INSERT INTO orders values (1,2,3);
END IF;

You were missing: END IF;

I had the same problem and none of these solutions worked and I don't know why, they worked for me in the past for similar problems.

Anyway to solve the problem I've just manually rebuild the package using node-pre-gyp

cd node_modules/bcrypt
node-pre-gyp rebuild

And everything worked as expected.

Hope this helps

If the above solutions don't work on ubuntu/linux then you can try this

sudo fuser -k -n tcp port

Run it several times to kill processes on your port of choosing. port could be 3000 for example. You would have killed all the processes if you see no output after running the command

For anyone looking at this old post, this is the easiest way to do it currently. It only requires an AngularJS $filter. Its like Willemoes answer, but shorter and easier to understand.

{ 
    "results": [
        {
            "id": 1,
            "name": "Test"
        },
        {
            "id": 2,
            "name": "Beispiel"
        },
        {
            "id": 3,
            "name": "Sample"
        }
    ] 
}

var object_by_id = $filter('filter')(foo.results, {id: 2 })[0];
// Returns { id: 2, name: "Beispiel" }

WARNING

As @mpgn says, this doesn't work properly. This will catch more results. Example: when you search 3 this will catch 23 too

There should be no semicolon here:

class WordGame;

...but there should be one at the end of your class definition:

...
private:
    string theWord;
}; // <-- Semicolon should be at the end of your class definition

select * from table where id in ( select id from table order by random() limit ((select count(*) from table)*55/100))

// to select 55 percent of rows randomly

You could could the digits using successive division by ten:

int a=0;

if (no < 0) {
    no = -no;
} else if (no == 0) {
    no = 1;
}

while (no > 0) {
    no = no / 10;
    a++;
}

System.out.println("Number of digits in given number is: "+a);

Sure, have a look at IDA Pro. They offer an eval version so you can try it out.

According to the previous answers this could happen for several reasons. For me the problem was referencing two different Bootstrap links without knowing, so removing one solves the problem.

In my case I included this one:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.5/css/bootstrap.min.css"
      integrity="sha384-AysaV+vQoT3kOAXZkl02PThvDr8HYKPZhNT5h/CXfBThSRXQ6jW5DO2ekP5ViFdi" crossorigin="anonymous">

and another offline one that I have already in my laptop.

I know what you're trying to do, but why not simply do this:

$('div').addClass('hover');

The class is already defined in your CSS...

As for you original question, this has been asked before and it is not possible unfortunately. e.g. http://forum.jquery.com/topic/jquery-triggering-css-pseudo-selectors-like-hover

However, your desired functionality may be possible if your Stylesheet is defined in Javascript. see: http://www.4pmp.com/2009/11/dynamic-css-pseudo-class-styles-with-jquery/

Hope this helps!

onChange will not call handleChange on mobile when using defaultChecked. As an alternative you can can use onClick and onTouchEnd.

<input onClick={this.handleChange} onTouchEnd={this.handleChange} type="checkbox" defaultChecked={!!this.state.complete} />;

A way of producing a data.frame and being able to do this in one line is to coerce all matrices/data frames passed to cbind into a data.frame while setting the column names attribute using setNames:

a = matrix(rnorm(10), ncol = 2)
b = matrix(runif(10), ncol = 2)

cbind(setNames(data.frame(a), c('n1', 'n2')), 
      setNames(data.frame(b), c('u1', 'u2')))

which produces:

          n1        n2         u1        u2
1 -0.2731750 0.5030773 0.01538194 0.3775269
2  0.5177542 0.6550924 0.04871646 0.4683186
3 -1.1419802 1.0896945 0.57212043 0.9317578
4  0.6965895 1.6973815 0.36124709 0.2882133
5  0.9062591 1.0625280 0.28034347 0.7517128

Unfortunately, there is no setColNames function analogous to setNames for data frames that returns the matrix after the column names, however, there is nothing to stop you from adapting the code of setNames to produce one:

setColNames <- function (object = nm, nm) {
    colnames(object) <- nm
    object
}

See this answer, the magrittr package contains functions for this.

Use

scanf("%d", &array[0]);

and use == for comparision instead of =

Get the indexpath of the row selected. Reload the table. In the heightForRowAtIndexPath method of UITableViewDelegate, set the height of the row selected to a different height and for the others return the normal row height

Upcasting is casting to a supertype, while downcasting is casting to a subtype. Upcasting is always allowed, but downcasting involves a type check and can throw a ClassCastException.

In your case, a cast from a Dog to an Animal is an upcast, because a Dog is-a Animal. In general, you can upcast whenever there is an is-a relationship between two classes.

Downcasting would be something like this:

Animal animal = new Dog();
Dog castedDog = (Dog) animal;

Basically what you're doing is telling the compiler that you know what the runtime type of the object really is. The compiler will allow the conversion, but will still insert a runtime sanity check to make sure that the conversion makes sense. In this case, the cast is possible because at runtime animal is actually a Dog even though the static type of animal is Animal.

However, if you were to do this:

Animal animal = new Animal();
Dog notADog = (Dog) animal;

You'd get a ClassCastException. The reason why is because animal's runtime type is Animal, and so when you tell the runtime to perform the cast it sees that animal isn't really a Dog and so throws a ClassCastException.

To call a superclass's method you can do super.method() or by performing the upcast.

To call a subclass's method you have to do a downcast. As shown above, you normally risk a ClassCastException by doing this; however, you can use the instanceof operator to check the runtime type of the object before performing the cast, which allows you to prevent ClassCastExceptions:

Animal animal = getAnimal(); // Maybe a Dog? Maybe a Cat? Maybe an Animal?
if (animal instanceof Dog) {
    // Guaranteed to succeed, barring classloader shenanigans
    Dog castedDog = (Dog) animal;
}

You just missed a little bit.

To get an embedded resource from any assembly, you have to mention the assembly name with your file name as I have mentioned here:

Assembly asm = Assembly.GetExecutingAssembly();
Stream iconStream = asm.GetManifestResourceStream(asm.GetName().Name + "." + "Desert.jpg");
BitmapImage bitmap = new BitmapImage();
bitmap.BeginInit();
bitmap.StreamSource = iconStream;
bitmap.EndInit();
image1.Source = bitmap;

If you want to replace a simple string and you don't need the abilities of regular expressions, you can just use replace, not replaceAll.

replace replaces each matching substring but does not interpret its argument as a regular expression.

str = xpath.replace(".", "/*/");

How to change the Push and Pop animations in a navigation based app...

For 2019, the "final answer!"

Preamble:

Say you are new to iOS development. Confusingly, Apple provide two transitions which can be used easily. These are: "crossfade" and "flip".

But of course, "crossfade" and "flip" are useless. They are never used. Nobody knows why Apple provided those two useless transitions!

So:

Say you want to do an ordinary, common, transition such as "slide". In that case, you have to do a HUGE amount of work!.

That work, is explained in this post.

Just to repeat:

Surprisingly: with iOS, if you want the simplest, most common, everyday transitions (such as an ordinary slide), you do have to all the work of implementing a full custom transition.

Here's how to do it ...

1. You need a custom UIViewControllerAnimatedTransitioning

1. You need a bool of your own like popStyle . (Is it popping on, or popping off?)

2. You must include transitionDuration (trivial) and the main call, animateTransition

3. In fact you must write two different routines for inside animateTransition. One for the push, and one for the pop. Probably name them animatePush and animatePop. Inside animateTransition, just branch on popStyle to the two routines

4. The example below does a simple move-over/move-off

5. In your animatePush and animatePop routines. You must get the "from view" and the "to view". (How to do that, is shown in the code example.)

6. and you must addSubview for the new "to" view.

7. and you must call completeTransition at the end of your anime

So ..

  class SimpleOver: NSObject, UIViewControllerAnimatedTransitioning {
        
        var popStyle: Bool = false
        
        func transitionDuration(
            using transitionContext: UIViewControllerContextTransitioning?) -> TimeInterval {
            return 0.20
        }
        
        func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {
            
            if popStyle {
                
                animatePop(using: transitionContext)
                return
            }
            
            let fz = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.from)!
            let tz = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.to)!
            
            let f = transitionContext.finalFrame(for: tz)
            
            let fOff = f.offsetBy(dx: f.width, dy: 55)
            tz.view.frame = fOff
            
            transitionContext.containerView.insertSubview(tz.view, aboveSubview: fz.view)
            
            UIView.animate(
                withDuration: transitionDuration(using: transitionContext),
                animations: {
                    tz.view.frame = f
            }, completion: {_ in 
                    transitionContext.completeTransition(true)
            })
        }
        
        func animatePop(using transitionContext: UIViewControllerContextTransitioning) {
            
            let fz = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.from)!
            let tz = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.to)!
            
            let f = transitionContext.initialFrame(for: fz)
            let fOffPop = f.offsetBy(dx: f.width, dy: 55)
            
            transitionContext.containerView.insertSubview(tz.view, belowSubview: fz.view)
            
            UIView.animate(
                withDuration: transitionDuration(using: transitionContext),
                animations: {
                    fz.view.frame = fOffPop
            }, completion: {_ in 
                    transitionContext.completeTransition(true)
            })
        }
    }

And then ...

2. Use it in your view controller.

Note: strangely, you only have to do this in the "first" view controller. (The one which is "underneath".)

With the one that you pop on top, do nothing. Easy.

So your class...

class SomeScreen: UIViewController {
}

becomes...

class FrontScreen: UIViewController,
        UIViewControllerTransitioningDelegate, UINavigationControllerDelegate {
    
    let simpleOver = SimpleOver()
    

    override func viewDidLoad() {
        
        super.viewDidLoad()
        navigationController?.delegate = self
    }

    func navigationController(
        _ navigationController: UINavigationController,
        animationControllerFor operation: UINavigationControllerOperation,
        from fromVC: UIViewController,
        to toVC: UIViewController) -> UIViewControllerAnimatedTransitioning? {
        
        simpleOver.popStyle = (operation == .pop)
        return simpleOver
    }
}

That's it.

Push and pop exactly as normal, no change. To push ...

let n = UIStoryboard(name: "nextScreenStoryboardName", bundle: nil)
          .instantiateViewController(withIdentifier: "nextScreenStoryboardID")
          as! NextScreen
navigationController?.pushViewController(n, animated: true)

and to pop it, you can if you like just do that on the next screen:

class NextScreen: TotallyOrdinaryUIViewController {
    
    @IBAction func userClickedBackOrDismissOrSomethingLikeThat() {
        
        navigationController?.popViewController(animated: true)
    }
}

Phew.

In bash, contrary to [, [[ prevents word splitting of variable values.

Guava has a method Ints.asList() for creating a List<Integer> backed by an int[] array. You can use this with Collections.sort to apply the Comparator to the underlying array.

List<Integer> integersList = Ints.asList(arr);
Collections.sort(integersList, Collections.reverseOrder());

Note that the latter is a live list backed by the actual array, so it should be pretty efficient.

You can do it like

OR

<button @click="Function1(); Function2();"></button>

Use nested dictionaries. Take a look:

INI File: example.ini

[Section]
Key = Value

Code:

class IniOpen:
    def __init__(self, file):
        self.parse = {}
        self.file = file
        self.open = open(file, "r")
        self.f_read = self.open.read()
        split_content = self.f_read.split("\n")

        section = ""
        pairs = ""

        for i in range(len(split_content)):
            if split_content[i].find("[") != -1:
                section = split_content[i]
                section = string_between(section, "[", "]")  # define your own function
                self.parse.update({section: {}})
            elif split_content[i].find("[") == -1 and split_content[i].find("="):
                pairs = split_content[i]
                split_pairs = pairs.split("=")
                key = split_pairs[0].trim()
                value = split_pairs[1].trim()
                self.parse[section].update({key: value})

    def read(self, section, key):
        try:
            return self.parse[section][key]
        except KeyError:
            return "Sepcified Key Not Found!"

    def write(self, section, key, value):
        if self.parse.get(section) is  None:
            self.parse.update({section: {}})
        elif self.parse.get(section) is not None:
            if self.parse[section].get(key) is None:
                self.parse[section].update({key: value})
            elif self.parse[section].get(key) is not None:
                return "Content Already Exists"

Apply code like so:

ini_file = IniOpen("example.ini")
print(ini_file.parse) # prints the entire nested dictionary
print(ini_file.read("Section", "Key") # >> Returns Value
ini_file.write("NewSection", "NewKey", "New Value"

The docs mention train_test_split is just a convenience function on top of shuffle split.

I just rearranged some of their code to make my own example. Note the actual solution is the middle block of code. The rest is imports, and setup for a runnable example.

from sklearn.model_selection import ShuffleSplit
from sklearn.utils import safe_indexing, indexable
from itertools import chain
import numpy as np
X = np.reshape(np.random.randn(20),(10,2)) # 10 training examples
y = np.random.randint(2, size=10) # 10 labels
seed = 1

cv = ShuffleSplit(random_state=seed, test_size=0.25)
arrays = indexable(X, y)
train, test = next(cv.split(X=X))
iterator = list(chain.from_iterable((
    safe_indexing(a, train),
    safe_indexing(a, test),
    train,
    test
    ) for a in arrays)
)
X_train, X_test, train_is, test_is, y_train, y_test, _, _  = iterator

print(X)
print(train_is)
print(X_train)

Now I have the actual indexes: train_is, test_is

You don't require broadcast receiver. If one would take some pain copy one of the api(serviceconnection) from above example by Stephen Donecker and paste it in google you would get this, https://www.concretepage.com/android/android-local-bound-service-example-with-binder-and-serviceconnection

The simplest and best way to get yesterday's date is:

subdate(current_date, 1)

Your query would be:

SELECT 
    url as LINK,
    count(*) as timesExisted,
    sum(DateVisited between UNIX_TIMESTAMP(subdate(current_date, 1)) and
        UNIX_TIMESTAMP(current_date)) as timesVisitedYesterday
FROM mytable
GROUP BY 1

For the curious, the reason that sum(condition) gives you the count of rows that satisfy the condition, which would otherwise require a cumbersome and wordy case statement, is that in mysql boolean values are 1 for true and 0 for false, so summing a condition effectively counts how many times it's true. Using this pattern can neaten up your SQL code.

You have to add

<script>jQuery.noConflict();</script>

after

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>

$("#locationthemes").prop("checked")

Use node.js for that, here is example how to install node by using brew on mac:

brew update && install node

Then run your program by typing node filename.js, and you can use console.log() for output.

Pandas Sorting 101

sort has been replaced in v0.20 by DataFrame.sort_values and DataFrame.sort_index. Aside from this, we also have argsort.

Here are some common use cases in sorting, and how to solve them using the sorting functions in the current API. First, the setup.

# Setup
np.random.seed(0)
df = pd.DataFrame({'A': list('accab'), 'B': np.random.choice(10, 5)})    
df                                                                                                                                        
   A  B
0  a  7
1  c  9
2  c  3
3  a  5
4  b  2

Sort by Single Column

For example, to sort df by column "A", use sort_values with a single column name:

df.sort_values(by='A')

   A  B
0  a  7
3  a  5
4  b  2
1  c  9
2  c  3

If you need a fresh RangeIndex, use DataFrame.reset_index.

Sort by Multiple Columns

For example, to sort by both col "A" and "B" in df, you can pass a list to sort_values:

df.sort_values(by=['A', 'B'])

   A  B
3  a  5
0  a  7
4  b  2
2  c  3
1  c  9

Sort By DataFrame Index

df2 = df.sample(frac=1)
df2

   A  B
1  c  9
0  a  7
2  c  3
3  a  5
4  b  2

You can do this using sort_index:

df2.sort_index()

   A  B
0  a  7
1  c  9
2  c  3
3  a  5
4  b  2

df.equals(df2)                                                                                                                            
# False
df.equals(df2.sort_index())                                                                                                               
# True

Here are some comparable methods with their performance:

Sort by List of Indices

For example,

idx = df2.index.argsort()
idx
# array([0, 7, 2, 3, 9, 4, 5, 6, 8, 1])

This "sorting" problem is actually a simple indexing problem. Just passing integer labels to iloc will do.

df.iloc[idx]

   A  B
1  c  9
0  a  7
2  c  3
3  a  5
4  b  2

E.g : "abcd: efg: 1006746" "bhddy: nshhf36: 1006754" "hfquv: nd: 5894254"

-Step 1: String firstString = "abcd: efg: 1006746";

-Step 2: String lastSevenNumber = firstString.substring(firstString.lastIndexOf(':'), firstString.length()).trim();

Quite a busy one-liner, but here it is:

1. First ensure your NumPy array, myarray, is normalised with the max value at 1.0.
2. Apply the colormap directly to myarray.
3. Rescale to the 0-255 range.
4. Convert to integers, using np.uint8().
5. Use Image.fromarray().

And you're done:

from PIL import Image
from matplotlib import cm
im = Image.fromarray(np.uint8(cm.gist_earth(myarray)*255))

with plt.savefig():

with im.save():

The following will only work if you do not have spaces in your input:

xargs -L 1
xargs --max-lines=1 # synonym for the -L option

from the man page:

-L max-lines
          Use at most max-lines nonblank input lines per command line.
          Trailing blanks cause an input line to be logically continued  on
          the next input line.  Implies -x.

Suppose your screen id has a pattern. Then you can use the following code to kill all the attached screen at once.

result=$(screen -ls | grep 'pattern_of_screen_id' -o)
for i in $result; 
do      
    `screen -X -S $i quit`;
done

You can use something like this :

SELECT
    Books.BookTitle,
    Books.Edition,
    Books.Year,
    Books.Pages,
    Books.Rating,
    Categories.Category,
    Publishers.Publisher,
    Writers.LastName
FROM Books
INNER JOIN Categories_Books ON Categories_Books._Books_ISBN = Books._ISBN
INNER JOIN Categories ON Categories._CategoryID = Categories_Books._Categories_Category_ID
INNER JOIN Publishers ON Publishers._Publisherid = Books.PublisherID
INNER JOIN Writers_Books ON Writers_Books._Books_ISBN = Books._ISBN
INNER JOIN Writers ON Writers.Writers_Books = _Writers_WriterID.

For this to work, your font also needs to be set to monospace.
If you think about it, lines can't otherwise line up perfectly perfectly.

This answer is detailed at sublime text forum:

On stackoverflow, see:

Michael Ruth's answer here: How to make ruler always be shown in Sublime text 2?

MattDMo's answer here: What is the default font of Sublime Text?

I have rulers set at the following:
30
50 (git commit message titles should be limited to 50 characters)
72 (git commit message details should be limited to 72 characters)
80 (Windows Command Console Window maxes out at 80 character width)

Other viewing environments that benefit from shorter lines: github: there is no word wrap when viewing a file online
So, I try to keep .js .md and other files at 70-80 characters.
Windows Console: 80 characters.

How about adding the filesize as a load parameter?

<script type='text/javascript' src='path/to/file/mylibrary.js?filever=<?=filesize('path/to/file/mylibrary.js')?>'></script>

So every time you update the file the "filever" parameter changes.

How about when you update the file and your update results in the same file size? what are the odds?

I opened the Visual Studio Code extensions folder and executed:

find * -maxdepth 2 -name "package.json" | xargs grep "name"

That gives you a list from which you can extract the extension names.

I needed to apply a translation to the Ok and Cancel buttons. I modified the code to except dynamic text (calls my translation function)

            // Remove the closing 'X' from the dialog_x000D_
            open: function(event, ui) { $(".ui-dialog-titlebar-close").hide(); },_x000D_
            width: 500,_x000D_

                click: function () {_x000D_
                    $(this).dialog("close");_x000D_
                    okAction();_x000D_
                }_x000D_
            },_x000D_
                {_x000D_
                text: localizationInstance.translate("Cancel"),_x000D_
                click: function() {_x000D_
                    $(this).dialog("close");_x000D_
                }_x000D_
            }],_x000D_
            close: function(event, ui) { $(this).remove(); },_x000D_
            resizable: false,_x000D_

        }).text(message);_x000D_
    }_x000D_
});

Do you mean like this

int index = 2;
string s = "hello";
Console.WriteLine(s[index]);

string also implements IEnumberable<char> so you can also enumerate it like this

foreach (char c in s)
    Console.WriteLine(c);

Long.valueOf(String s) - obviously due care must be taken to protect against non-numbers if that is possible in your code.

If you want to just toggle visibility and still keep the input in DOM:

<input class="txt" type="password" [(ngModel)]="input_pw" 
 [style.visibility]="isHidden? 'hidden': 'visible'">

The other way around is as per answer by rrd, which is to use HTML hidden attribute. In an HTML element if hidden attribute is set to true browsers are supposed to hide the element from display, but the problem is that this behavior is overridden if the element has an explicit display style mentioned.

.hasDisplay {_x000D_
  display: block;_x000D_
}

<input class="hasDisplay" hidden value="shown" />_x000D_
<input hidden value="not shown">

To overcome this you can opt to use an explicit css for [hidden] that overrides the display;

[hidden] {
  display: none !important;
}

Yet another way is to have a is-hidden class and do:

<input [class.is-hidden]="isHidden"/>

.is-hidden {
      display: none;
 }

If you use display: none the element will be skipped from the static flow and no space will be allocated for the element, if you use visibility: hidden it will be included in the flow and a space will be allocated but it will be blank space.

The important thing is to use one way across an application rather than mixing different ways thereby making the code less maintainable.

If you want to remove it from DOM

<input class="txt" type="password" [(ngModel)]="input_pw" *ngIf="!isHidden">

Code will be As below.

[textarea id:message 0x0 class:custom-class "Insert text here"]<!-- No Rows No columns -->

[textarea id:message x2 class:custom-class "Insert text here"]<!-- Only Rows -->

[textarea id:message 12x class:custom-class "Insert text here"]<!-- Only Columns -->

[textarea id:message 10x2 class:custom-class "Insert text here"]<!-- Both Rows and Columns -->

I was working on re-ordering a lot of tables and didn't want to have to write the same queries over and over so I made a script to do it all for me. Essentially, it:

1. Gets the table creation SQL from pg_dump
2. Gets all available columns from the dump
3. Puts the columns in the desired order
4. Modifies the original pg_dump query to create a re-ordered table with data
5. Drops old table
6. Renames new table to match old table

It can be used by running the following simple command:

./reorder.py -n schema -d database table \
    first_col second_col ... penultimate_col ultimate_col --migrate

It prints out the sql so you can verify and test it, that was a big reason I based it on pg_dump. You can find the github repo here.

There are a number of possible ways to do this, but have a google for tkprof

There's no GUI... it's entirely command line and possibly a touch intimidating for Oracle beginners; but it's very powerful.

This link looks like a good start:

http://www.oracleutilities.com/OSUtil/tkprof.html

You should probably re-write the script to return a value rather than output it. Instead of:

a=$( script.sh ) # Now a is a string, either "success" or "Failed"
case "$a" in
   success) echo script succeeded;;
   Failed) echo script failed;;
esac

you would be able to do:

if script.sh > /dev/null; then
    echo script succeeded
else
    echo script failed
fi

It is much simpler for other programs to work with you script if they do not have to parse the output. This is a simple change to make. Just exit 0 instead of printing success, and exit 1 instead of printing Failed. Of course, you can also print those values as well as exiting with a reasonable return value, so that wrapper scripts have flexibility in how they work with the script.

/* this will change the HTML content with the new HTML that you want to update in your modal without too many resets... */

    $('#myModal').modal('show');
});

It does this by default. It returns null.

LinearLayout : A layout that organizes its children into a single horizontal or vertical row. It creates a scrollbar if the length of the window exceeds the length of the screen.It means you can align views one by one (vertically/ horizontally).

RelativeLayout : This enables you to specify the location of child objects relative to each other (child A to the left of child B) or to the parent (aligned to the top of the parent). It is based on relation of views from its parents and other views.

WebView : to load html, static or dynamic pages.

TLDR: Aggregation pipeline is faster as compared to conventional .find().sort().

Now moving to the real explanation. There are two ways to perform sorting operations in MongoDB:

1. Using .find() and .sort().
2. Or using the aggregation pipeline.

As suggested by many .find().sort() is the simplest way to perform the sorting.

.sort([("field1",pymongo.ASCENDING), ("field2",pymongo.DESCENDING)])

However, this is a slow process compared to the aggregation pipeline.

Coming to the aggregation pipeline method. The steps to implement simple aggregation pipeline intended for sorting are:

1. $match (optional step)
2. $sort

NOTE: In my experience, the aggregation pipeline works a bit faster than the .find().sort() method.

Here's an example of the aggregation pipeline.

db.collection_name.aggregate([{
    "$match": {
        # your query - optional step
    }
},
{
    "$sort": {
        "field_1": pymongo.ASCENDING,
        "field_2": pymongo.DESCENDING,
        ....
    }
}])

Try this method yourself, compare the speed and let me know about this in the comments.

Edit: Do not forget to use allowDiskUse=True while sorting on multiple fields otherwise it will throw an error.

The correct way would be to specify the input as per your requirement which will give you more flexibility.

The present definition includes the following

LTS : 'h:mm:ss A', LT : 'h:mm A', L : 'MM/DD/YYYY', LL : 'MMMM D, YYYY', LLL : 'MMMM D, YYYY h:mm A', LLLL : 'dddd, MMMM D, YYYY h:mm A'

You can use any of these or change the input passed into moment().format(). For example, for your case you can pass moment.utc(dateTime).format('MMMM D, YYYY').

string saveStaff = "INSERT into student (stud_id,stud_name) " + " VALUES ('" + SI+ "', '" + SN + "');";
cmd = new SqlCommand(saveStaff,con);
cmd.ExecuteNonQuery();

You are applying the formatting to the workbook that has the code, not the added workbook. You'll want to get in the habit of fully qualifying sheet and range references. The code below does that and works for me in Excel 2010:

Sub test()
Dim wb As Excel.Workbook
Set wb = Workbooks.Add
With wb.Sheets(1)
    .Range("A1") = "Acctdate"
    .Range("B1") = "Ledger"
    .Range("C1") = "CY"
    .Range("D1") = "BusinessUnit"
    .Range("E1") = "OperatingUnit"
    .Range("F1") = "LOB"
    .Range("G1") = "Account"
    .Range("H1") = "TreatyCode"
    .Range("I1") = "Amount"
    .Range("J1") = "TransactionCurrency"
    .Range("K1") = "USDEquivalentAmount"
    .Range("L1") = "KeyCol"
    .Range("A2", "A50000").Value = Me.TextBox3.Value
    .Range("A2", "A50000").NumberFormat = "yyyy-mm-dd"
End With
End Sub

You can check if your string starts with http or https using the small function below.

function has_prefix($string, $prefix) {
   return substr($string, 0, strlen($prefix)) == $prefix;
}

$url   = 'http://www.google.com';
echo 'the url ' . (has_prefix($url, 'http://')  ? 'does' : 'does not') . ' start with http://';
echo 'the url ' . (has_prefix($url, 'https://') ? 'does' : 'does not') . ' start with https://';

Here's another solution using a package solely dedicated to working with dates and times in R:

library(tidyverse)
library(lubridate)

(df <- tibble(ID = 1:3, Date = c("2004-02-06" , "2006-03-14", "2007-07-16")))
#> # A tibble: 3 x 2
#>      ID Date      
#>   <int> <chr>     
#> 1     1 2004-02-06
#> 2     2 2006-03-14
#> 3     3 2007-07-16

df %>%
  mutate(
    Date = ymd(Date),
    Month_Yr = format_ISO8601(Date, precision = "ym")
  )
#> # A tibble: 3 x 3
#>      ID Date       Month_Yr
#>   <int> <date>     <chr>   
#> 1     1 2004-02-06 2004-02 
#> 2     2 2006-03-14 2006-03 
#> 3     3 2007-07-16 2007-07

Here is a nice guide for doing exactly that:

http://mycodde.blogspot.com.ar/2014/12/multiple-recaptcha-demo-same-page.html

Basically you add some parameters to the api call and manually render each recaptcha:

<script src="https://www.google.com/recaptcha/api.js?onload=myCallBack&render=explicit" async defer></script>
<script>
        var recaptcha1;
        var recaptcha2;
        var myCallBack = function() {
            //Render the recaptcha1 on the element with ID "recaptcha1"
            recaptcha1 = grecaptcha.render('recaptcha1', {
                'sitekey' : '6Lc_0f4SAAAAAF9ZA', //Replace this with your Site key
                'theme' : 'light'
            });

            //Render the recaptcha2 on the element with ID "recaptcha2"
            recaptcha2 = grecaptcha.render('recaptcha2', {
                'sitekey' : '6Lc_0f4SAAAAAF9ZA', //Replace this with your Site key
                'theme' : 'dark'
            });
        };
</script>

PS: The "grecaptcha.render" method receives an ID

If you're using Unity, you don't need to change this in Xcode, you can apply a compile flag in the metadata for the specific file(s), right inside Unity. Just select them in the Project panel, and apply from the Inspector panel. This is essential if you plan on using Cloud Build.

Any attribute can be selected using [attribute_name=value] way. See the sample here:

var value = $("[name='nameofobject']");

For an HTTP-based server there is a Python script to find the server version at: http://svn.apache.org/repos/asf/subversion/trunk/tools/client-side/server-version.py

You can get the client version with

`svn --version`

You could try

cat FILE | awk '{print NF}'

The (^) XOR operator generates 1 when it is applied on two different bits (0 and 1). It generates 0 when it is applied on two same bits (0 and 0 or 1 and 1).

You can't hide it, but you can disable it by overriding the CreateParams property of the form.

private const int CP_NOCLOSE_BUTTON = 0x200;
protected override CreateParams CreateParams
{
    get
    {
       CreateParams myCp = base.CreateParams;
       myCp.ClassStyle = myCp.ClassStyle | CP_NOCLOSE_BUTTON ;
       return myCp;
    }
}

In 0.18.1 groupby together with count does not give the frequency of unique values:

>>> df
   a
0  a
1  b
2  s
3  s
4  b
5  a
6  b

>>> df.groupby('a').count()
Empty DataFrame
Columns: []
Index: [a, b, s]

However, the unique values and their frequencies are easily determined using size:

>>> df.groupby('a').size()
a
a    2
b    3
s    2

With df.a.value_counts() sorted values (in descending order, i.e. largest value first) are returned by default.

In Eclipse it's on templates.

SQL tables are not ordered by default, and asking for the n-th row from a non ordered set of rows has no meaning as it could potentially return a different row each time unless you specify an ORDER BY:

select * from customer order by id where row_number() = 3

(sometimes MySQL tables are shown with an internal order but you cannot rely on this behaviour). Then you can use LIMIT offset, row_count, with a 0-based offset so row number 3 becomes offset 2:

select * from customer order by id
limit 2, 1

or you can use LIMIT row_count OFFSET offset:

select * from customer order by id
limit 1 offset 2

I wasn't able to get Surya's and Matteo's solutions to work. For example, "(#f1)" was just displayed as text, and didn't become a link. However, their solutions led me to slightly different solution. (I also formatted the footnote and the link back to the original superscript a bit differently.)

In the body of the text:

Yadda yadda<a href="#note1" id="note1ref"><sup>1</sup></a>

At the end of the document:

<a id="note1" href="#note1ref"><sup>1</sup></a>Here is the footnote text.

Clicking on the superscript in the footnote returns to the superscript in the original text.

My best way to do this is, that i open the Code Definition Window, under View -> Code Definition Window or press Ctrl + W,D .

And then i got it floated and i have the definitions of methods in separate windows.

FINDSTR has a color bug that I described and solved at https://superuser.com/questions/1535810/is-there-a-better-way-to-mitigate-this-obscure-color-bug-when-piping-to-findstr/1538802?noredirect=1#comment2339443_1538802

To summarize that thread, the bug is that if input is piped to FINDSTR within a parenthesized block of code, inline ANSI escape colorcodes stop working in commands executed later. An example of inline colorcodes is: echo %magenta%Alert: Something bad happened%yellow% (where magenta and yellow are vars defined earlier in the .bat file as the corresponding ANSI escape colorcodes).

My initial solution was to call a do-nothing subroutine after the FINDSTR. Somehow the call or the return "resets" whatever needs to be reset.

Later I discovered another solution that presumably is more efficient: place the FINDSTR phrase within parentheses, as in the following example: echo success | ( FINDSTR /R success ) Placing the FINDSTR phrase within a nested block of code appears to isolate FINDSTR's colorcode bug so it won't affect what's outside the nested block. Perhaps this technique will solve some other undesired FINDSTR side effects too.

jQuery BBQ (Back Button & Query Library)

Just declare a function

Size screenSize() {

The database.yml is the file where you set up all the information to connect to the database. It differs depending on the kind of DB you use. You can find more information about this in the Rails Guide or any tutorial explaining how to setup a rails project.

The information in the database.yml file is scoped by environment, allowing you to get a different setting for testing, development or production. It is important that you keep those distinct if you don't want the data you use for development deleted by mistake while running your test suite.

Regarding source control, you should not commit this file but instead create a template file for other developers (called database.yml.template). When deploying, the convention is to create this database.yml file in /shared/config directly on the server.

With SVN: svn propset svn:ignore config "database.yml"

With Git: Add config/database.yml to the .gitignore file or with git-extra git ignore config/database.yml

Applying the BoxCox transformation to data, without the need of any underlying model, can be done currently using the package geoR. Specifically, you can use the function boxcoxfit() for finding the best parameter and then predict the transformed variables using the function BCtransform().

I have the same issue. I click ok in xcode and when launching the app on my iPhone I'm asked if I want to trust this application. Doing it, the app runs and further build-and-run from xcode went without any issue until deleting the app from the iPhone and reinstalling it. Then goto first line ;-)

Not a queue example, but extremely simple :)

class MyHouse {
    private boolean pizzaArrived = false;

    public void eatPizza(){
        synchronized(this){
            while(!pizzaArrived){
                wait();
            }
        }
        System.out.println("yumyum..");
    }

    public void pizzaGuy(){
        synchronized(this){
             this.pizzaArrived = true;
             notifyAll();
        }
    }
}

Some important points:
1) NEVER do

 if(!pizzaArrived){
     wait();
 }

Always use while(condition), because

• a) threads can sporadically awake from waiting state without being notified by anyone. (even when the pizza guy didn't ring the chime, somebody would decide try eating the pizza.).
• b) You should check for the condition again after acquiring the synchronized lock. Let's say pizza don't last forever. You awake, line-up for the pizza, but it's not enough for everybody. If you don't check, you might eat paper! :) (probably better example would be while(!pizzaExists){ wait(); }.

2) You must hold the lock (synchronized) before invoking wait/nofity. Threads also have to acquire lock before waking.

3) Try to avoid acquiring any lock within your synchronized block and strive to not invoke alien methods (methods you don't know for sure what they are doing). If you have to, make sure to take measures to avoid deadlocks.

4) Be careful with notify(). Stick with notifyAll() until you know what you are doing.

5)Last, but not least, read Java Concurrency in Practice!

I did this in MySql and it updated multiple columns in a single record, so try this if you are using MySql as your server:

"UPDATE creditor_tb SET credit_amount='" & CDbl(cur_amount) & "'
                   , totalamount_to_pay='" & current_total & "',   
        WHERE credit_id='" & lbcreditId.Text & "'". 

However, I was coding in vb.net using MySql server, but you can take it to your favorite programming language as far as you are using MySql as your server.

I recently had this same problem. Unfortunately, NotifyIcon is only a Windows.Forms control at the moment, if you want to use it you are going to have to include that part of the framework. I guess that depends how much of a WPF purist you are.

If you want a quick and easy way of getting started check out this WPF NotifyIcon control on the Code Project which does not rely on the WinForms NotifyIcon at all. A more recent version seems to be available on the author's website and as a NuGet package. This seems like the best and cleanest way to me so far.

• Rich ToolTips rather than text
• WPF context menus and popups
• Command support and routed events
• Flexible data binding
• Rich balloon messages rather than the default messages provides by the OS

Check it out. It comes with an amazing sample app too, very easy to use, and you can have great looking Windows Live Messenger style WPF popups, tooltips, and context menus. Perfect for displaying an RSS feed, I am using it for a similar purpose.

Yes, use the rendered attribute.

<h:form rendered="#{some boolean condition}">

You usually tie it to the model rather than letting the model grab the component and manipulate it.

E.g.

<h:form rendered="#{bean.booleanValue}" />
<h:form rendered="#{bean.intValue gt 10}" />
<h:form rendered="#{bean.objectValue eq null}" />
<h:form rendered="#{bean.stringValue ne 'someValue'}" />
<h:form rendered="#{not empty bean.collectionValue}" />
<h:form rendered="#{not bean.booleanValue and bean.intValue ne 0}" />
<h:form rendered="#{bean.enumValue eq 'ONE' or bean.enumValue eq 'TWO'}" />

Note the importance of keyword based EL operators such as gt, ge, le and lt instead of >, >=, <= and < as angle brackets < and > are reserved characters in XML. See also this related Q&A: Error parsing XHTML: The content of elements must consist of well-formed character data or markup.

As to your specific use case, let's assume that the link is passing a parameter like below:

<a href="page.xhtml?form=1">link</a>

You can then show the form as below:

<h:form rendered="#{param.form eq '1'}">

(the #{param} is an implicit EL object referring to a Map representing the request parameters)

First of all you can't make a POST request using JSONP.

What basically is happening is that dynamically a script tag is inserted to load your data. Therefore only GET requests are possible.

Furthermore your data has to be wrapped in a callback function which is called after the request is finished to load the data in a variable.

This whole process is automated by jQuery for you. Just using $.getJSON on an external domain doesn't always work though. I can tell out of personal experience.

The best thing to do is adding &callback=? to you url.

At the server side you've got to make sure that your data is wrapped in this callback function.

ie.

echo $_GET['callback'] . '(' . $data . ')';

EDIT:

Don't have enough rep yet to comment on Liam's answer so therefore the solution over here.

Replace Liam's line

 echo "{'fullname' : 'Jeff Hansen'}";

with

 echo $_GET['callback'] . '(' . "{'fullname' : 'Jeff Hansen'}" . ')';

Why to annoy the user with three different Dialog Boxes to enter things, why not do all this in one go in a single Dialog and save time, instead of testing the patience of the USER ?

You can add everything in a single Dialog, by putting all the fields on your JPanel and then adding this JPanel to your JOptionPane. Below code can clarify a bit more :

import java.awt.*;
import java.util.*;
import javax.swing.*;

public class AverageExample
{
    private double[] marks;
    private JTextField[] marksField;
    private JLabel resultLabel;

    public AverageExample()
    {
        marks = new double[3];
        marksField = new JTextField[3];
        marksField[0] = new JTextField(10);
        marksField[1] = new JTextField(10);
        marksField[2] = new JTextField(10);
    }

    private void displayGUI()
    {
        int selection = JOptionPane.showConfirmDialog(
                null, getPanel(), "Input Form : "
                                , JOptionPane.OK_CANCEL_OPTION
                                , JOptionPane.PLAIN_MESSAGE);

        if (selection == JOptionPane.OK_OPTION) 
        {
            for ( int i = 0; i < 3; i++)
            {
                marks[i] = Double.valueOf(marksField[i].getText());             
            }
            Arrays.sort(marks);
            double average = (marks[1] + marks[2]) / 2.0;
            JOptionPane.showMessageDialog(null
                    , "Average is : " + Double.toString(average)
                    , "Average : "
                    , JOptionPane.PLAIN_MESSAGE);
        }
        else if (selection == JOptionPane.CANCEL_OPTION)
        {
            // Do something here.
        }
    }

        JPanel centerPanel = new JPanel();
        centerPanel.setLayout(new GridLayout(3, 2, 5, 5));
        centerPanel.setBorder(
            BorderFactory.createEmptyBorder(5, 5, 5, 5));
        centerPanel.setOpaque(true);
        centerPanel.setBackground(Color.WHITE);

        JLabel mLabel1 = new JLabel("Enter Marks 1 : ");
        JLabel mLabel2 = new JLabel("Enter Marks 2 : ");
        JLabel mLabel3 = new JLabel("Enter Marks 3 : ");

        centerPanel.add(mLabel1);
        centerPanel.add(marksField[0]);
        centerPanel.add(mLabel2);
        centerPanel.add(marksField[1]);
        centerPanel.add(mLabel3);
        centerPanel.add(marksField[2]);

        basePanel.add(centerPanel);

        return basePanel;
    }

    public static void main(String... args)
    {
        SwingUtilities.invokeLater(new Runnable()
        {

The code commented works as well, just choose which do you prefer

does your proxy require you to authenticate? because if it does, you might want you configure your proxy like this.

placeholder names. username is a placeholder for your actual username. password is a placeholder for your actual password. proxy.company.com is a placeholder for your actualy proxy *port" is your actualy port the proxy goes through. its usualy 8080

npm config set proxy "http://username:[email protected]:port"
npm config set https-proxy "http://username:[email protected]:port"

Cleaner and more reusable approach is

define text size in dimens.xml file inside res/values/ directory:

</resources>
   <dimen name="text_medium">14sp</dimen>
</resources>

and then apply it to the TextView:

textView.setTextSize(TypedValue.COMPLEX_UNIT_PX, context.getResources().getDimension(R.dimen.text_medium));

Click "View Detail..." a window will open where you can expand the "Inner Exception" my guess is that when you try to delete the record there is a reference constraint violation. The inner exception will give you more information on that so you can modify your code to remove any references prior to deleting the record.

Technically speaking you have a few options here:

If you are using an IDE like Sublime Text and integrated MSN plugin for Typescript: http://blogs.msdn.com/b/interoperability/archive/2012/10/01/sublime-text-vi-emacs-typescript-enabled.aspx you can create a build system which compile the .ts source to .js automatically. Here is the explanation how you can do it: How to configure a Sublime Build System for TypeScript.

You can define even to compile the source code to destination .js file on file save. There is a sublime package hosted on github: https://github.com/alexnj/SublimeOnSaveBuild which make this happen, only you need to include the ts extension in the SublimeOnSaveBuild.sublime-settings file.

Another possibility would be to compile each file in the command line. You can compile even multiple files at once by separating them with spaces like so: tsc foo.ts bar.ts. Check this thread: How can I pass multiple source files to the TypeScript compiler?, but i think the first option is more handy.

As suggested above, i had similar issue with mysql-5.7.18,
i did this in this way

1. Executed this command from "MYSQL_HOME\bin\mysqld.exe --initialize-insecure"
2. then started "MYSQL_HOME\bin\mysqld.exe"
3. Connect workbench to this localhost:3306 with username 'root'
4. then executed this query "SET PASSWORD FOR 'root'@'localhost' = 'root';"

password was also updated successfully.

After trying everything that's out there without success, I found out, by accident, a functional and very easy way to get the action bar's default height.

Only tested in API 25 and 24

C#

Resources.GetDimensionPixelSize(Resource.Dimension.abc_action_bar_default_height_material); 

Java

getResources().getDimensionPixelSize(R.dimen.abc_action_bar_default_height_material);

In the current order? I'd say array_slice(). Since it's a built in function it will be faster than looping through the array while keeping track of an incrementing index until N.

In my case the number of items in the ListBox is dynamic so I didn't want to use the Height property. I used MaxHeight instead and it works nicely. The scrollbar appears when it fills the space I've allocated for it.

Since the rules are running in JavaScript, why not disable them using javascript (or in my examples case, jQuery)?

$('#fieldId').attr('disabled', 'disabled'); //Disable
$('#fieldId').removeAttr('disabled'); //Enable

UPDATE

The attr function is no longer the primary approach to this, as was pointed out in the comments below. This is now done with the prop function.

$( "input" ).prop( "disabled", true ); //Disable
$( "input" ).prop( "disabled", false ); //Enable

a = []
a.append(["Nick", 30, "Doctor"])
a.append(["John",  8, "Student"])
a.append(["Paul",  8,"Car Dealer"])
a.append(["Mark", 66, "Retired"])
print a

[['Nick', 30, 'Doctor'], ['John', 8, 'Student'], ['Paul', 8, 'Car Dealer'], ['Mark', 66, 'Retired']]

def _cmp(a,b):     

    if a[1]<b[1]:
        return -1
    elif a[1]>b[1]:
        return 1
    else:
        return 0

sorted(a,cmp=_cmp)

[['John', 8, 'Student'], ['Paul', 8, 'Car Dealer'], ['Nick', 30, 'Doctor'], ['Mark', 66, 'Retired']]

def _key(list_ele):

    return list_ele[1]

sorted(a,key=_key)

[['John', 8, 'Student'], ['Paul', 8, 'Car Dealer'], ['Nick', 30, 'Doctor'], ['Mark', 66, 'Retired']]

You'll get that error once your numbers are greater than sys.maxsize:

>>> p = [sys.maxsize]
>>> preds[0] = p
>>> p = [sys.maxsize+1]
>>> preds[0] = p
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OverflowError: Python int too large to convert to C long

You can confirm this by checking:

>>> import sys
>>> sys.maxsize
2147483647

To take numbers with larger precision, don't pass an int type which uses a bounded C integer behind the scenes. Use the default float:

>>> preds = np.zeros((1, 3))

You can try this. its working for me 'name' is a property in arr.

repeat="item in (tagWordOptions | filter:{ name: $select.search } ) track by $index

This is may be late but for those who are still looking for answer for this I found a project on git hub and this is the only one that actually fit my needs. android-materialshadowninepatch

Just add this line on your build.gradle dependency

compile 'com.h6ah4i.android.materialshadowninepatch:materialshadowninepatch:0.6.3'

cheers. thumbs up for the creator ! happycodings

To get the output of ls, use stdout=subprocess.PIPE.

>>> proc = subprocess.Popen('ls', stdout=subprocess.PIPE)
>>> output = proc.stdout.read()
>>> print output
bar
baz
foo

The command cdrecord --help outputs to stderr, so you need to pipe that indstead. You should also break up the command into a list of tokens as I've done below, or the alternative is to pass the shell=True argument but this fires up a fully-blown shell which can be dangerous if you don't control the contents of the command string.

>>> proc = subprocess.Popen(['cdrecord', '--help'], stderr=subprocess.PIPE)
>>> output = proc.stderr.read()
>>> print output
Usage: wodim [options] track1...trackn
Options:
    -version    print version information and exit
    dev=target  SCSI target to use as CD/DVD-Recorder
    gracetime=# set the grace time before starting to write to #.
...

If you have a command that outputs to both stdout and stderr and you want to merge them, you can do that by piping stderr to stdout and then catching stdout.

subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)

As mentioned by Chris Morgan, you should be using proc.communicate() instead of proc.read().

>>> proc = subprocess.Popen(['cdrecord', '--help'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
>>> out, err = proc.communicate()
>>> print 'stdout:', out
stdout: 
>>> print 'stderr:', err
stderr:Usage: wodim [options] track1...trackn
Options:
    -version    print version information and exit
    dev=target  SCSI target to use as CD/DVD-Recorder
    gracetime=# set the grace time before starting to write to #.
...

Ok, this is not really an answer to the question, but if you are looking up how to make your own delegate maybe something far simpler could be a better answer for you.

I hardly implement my delegates because I rarely need. I can have ONLY ONE delegate for a delegate object. So if you want your delegate for one way communication/passing data than you are much better of with notifications.

NSNotification can pass objects to more than one recipients and it is very easy to use. It works like this:

MyClass.m file should look like this

#import "MyClass.h"
@implementation MyClass 

- (void) myMethodToDoStuff {
//this will post a notification with myClassData (NSArray in this case)  in its userInfo dict and self as an object
[[NSNotificationCenter defaultCenter] postNotificationName:@"myClassUpdatedData"
                                                    object:self
                                                  userInfo:[NSDictionary dictionaryWithObject:selectedLocation[@"myClassData"] forKey:@"myClassData"]];
}
@end

To use your notification in another classes: Add class as an observer:

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(otherClassUpdatedItsData:) name:@"myClassUpdatedData" object:nil];

Implement the selector:

- (void) otherClassUpdatedItsData:(NSNotification *)note {
    NSLog(@"*** Other class updated its data ***");
    MyClass *otherClass = [note object];  //the object itself, you can call back any selector if you want
    NSArray *otherClassData = [note userInfo][@"myClassData"]; //get myClass data object and do whatever you want with it
}

Don't forget to remove your class as an observer if

- (void)dealloc
{
    [[NSNotificationCenter defaultCenter] removeObserver:self];
}

I had the same issue. I used Worksheet instead of Worksheets and it was resolved. Not sure what the difference is between them.

I went threw the same problem. None of the answers above worked for me, but i ended finding the solution on my own. The ipa file wasn't created because there was library files (libXXX.a) in Target-> Build Phases -> Copy Bundle with resources

Hope it will help someone :)

IMHO, this looks better:

Chess *array = malloc(size * sizeof(Chess)); // array of pointers of size `size`

for ( int i =0; i < SOME_VALUE; ++i )
{
    array[i] = (Chess) malloc(sizeof(Chess));
}

at april 2020 on mac os catalina you just need to open the desktop application

1).(expression1 | expression2), | operator will evaluate expression2 irrespective of whether the result of expression1 is true or false.

Example:

class Or 
{
    public static void main(String[] args) 
    {
        boolean b=true;

        if (b | test());
    }

    static boolean test()
    {
        System.out.println("No short circuit!");
        return false;
    }
}

2).(expression1 || expression2), || operator will not evaluate expression2 if expression1 is true.

Example:

class Or 
{
    public static void main(String[] args) 
    {
        boolean b=true;

        if (b || test())
        {
            System.out.println("short circuit!");
        }
    }

    static boolean test()
    {
        System.out.println("No short circuit!");
        return false;
    }
}

Here's a way that allows for ties for the cut-off score.

author_count = Author.objects.count()
cut_off_score = Author.objects.order_by('-score').values_list('score')[min(30, author_count)]
top_authors = Author.objects.filter(score__gte=cut_off_score).order_by('last_name')

You may get more than 30 authors in top_authors this way and the min(30,author_count) is there incase you have fewer than 30 authors.

I had the same problem when we used one database for two applications. Setting disableDatabaseInitialization="true" in context type section works for me.

<entityFramework>
<providers>
  <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
</providers>
<contexts>
  <context type="PreferencesContext, Preferences" disableDatabaseInitialization="true">
    <databaseInitializer type="System.Data.Entity.MigrateDatabaseToLatestVersion`2[[PreferencesContext, Preferences], [Migrations.Configuration, Preferences]], EntityFramework" />
  </context>
</contexts>

See more details https://msdn.microsoft.com/en-us/data/jj556606.aspx

Only way known for me is to looping through all array:

var index=-1;
for(var i=0;i<Data.length;i++)
  if(Data[i].name==="John"){index=i;break;}

or case insensitive:

var index=-1;
for(var i=0;i<Data.length;i++)
  if(Data[i].name.toLowerCase()==="john"){index=i;break;}

On result variable index contain index of object or -1 if not found.

-webkit-transform is no more needed

ms already support rotation ( -ms-transform: rotate(-10deg); )

try this:

li a {
   ...

    -webkit-transform: rotate(-10deg);
    -moz-transform: rotate(-10deg);
    -o-transform: rotate(-10deg);
    -ms-transform: rotate(-10deg);
    -sand-transform: rotate(10deg);
    display: block;
    position: fixed;
    }

ExpectedConditions is obsolete, so:

        WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(15));
        wait.Until(SeleniumExtras.WaitHelpers.ExpectedConditions.AlertIsPresent());

C# Selenium 'ExpectedConditions is obsolete'

However the cmd/batch version works you can run into an issue when you want to define an eventID which is higher then 1000. For event creation with an eventID of 1000+ i'll use powershell like this:

$evt=new-object System.Diagnostics.Eventlog(“Define Logbook”)
$evt.Source=”Define Source”
$evtNumber=Define Eventnumber
$evtDescription=”Define description”
$infoevent=[System.Diagnostics.EventLogEntryType]::Define error level
$evt.WriteEntry($evtDescription,$infoevent,$evtNumber) 

Sample:

$evt=new-object System.Diagnostics.Eventlog(“System”)
$evt.Source=”Tcpip”
$evtNumber=4227
$evtDescription=”This is a Test Event”
$infoevent=[System.Diagnostics.EventLogEntryType]::Warning
$evt.WriteEntry($evtDescription,$infoevent,$evtNumber)

For pages on the same domain and different subdomain, you can set the document.domain property via javascript.

Both the parent frame and the iframe need to set their document.domain to something that is common betweeen them.

i.e. www.foo.mydomain.com and api.foo.mydomain.com could each use either foo.mydomain.com or just mydomain.com and be compatible (no, you can't set them both to com, for security reasons...)

also, note that document.domain is a one way street. Consider running the following three statements in order:

// assume we're starting at www.foo.mydomain.com
document.domain = "foo.mydomain.com" // works
document.domain = "mydomain.com" // works
document.domain = "foo.mydomain.com" // throws a security exception

Modern browsers can also use window.postMessage to talk across origins, but it won't work in IE6. https://developer.mozilla.org/en/DOM/window.postMessage

I had this question, but with a twist - I was trying to log different content to different files. I had information for a LowLevel debug log, and a HighLevel user log. I wanted the LowLevel to go to only one file, and the HighLevel to go to both a file, and a syslogd.

My solution was to configure the 3 appenders, and then setup the logging like this:

log4j.threshold=ALL
log4j.rootLogger=,LowLogger

log4j.logger.HighLevel=ALL,Syslog,HighLogger
log4j.additivity.HighLevel=false

The part that was difficult for me to figure out was that the 'log4j.logger' could have multiple appenders listed. I was trying to do it one line at a time.

Hope this helps someone at some point!

You can use Replace function as;

REPLACE ('Your String with cityname here', 'cityname', 'xyz')
--Results
'Your String with xyz here'

If you apply this to a table column where stringColumnName, cityName both are columns of YourTable

SELECT REPLACE(stringColumnName, cityName, '')
FROM YourTable

Or if you want to remove 'cityName' string from out put of a column then

SELECT REPLACE(stringColumnName, 'cityName', '')
FROM yourTable

EDIT: Since you have given more details now, REPLACE function is not the best method to sort your problem. Following is another way of doing it. Also @MartinSmith has given a good answer. Now you have the choice to select again.

SELECT RIGHT (O.Ort, LEN(O.Ort) - LEN(C.CityName)-1) As WithoutCityName
FROM   tblOrtsteileGeo O
       JOIN dbo.Cities C
         ON C.foo = O.foo
WHERE  O.GKZ = '06440004'

This worked for me... try it

let image : UIImage = UIImage(named: "LogoName")
let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 25, height: 25))
imageView.contentMode = .scaleAspectFit
imageView.image = image
navigationItem.titleView = imageView

i know this thread is kind of old and the original question was for an easy solution but if it's supposed to be really fast, you should use a char array.

public static String pad(String str, int size, char padChar)
{
    if (str.length() < size)
    {
        char[] temp = new char[size];
        int i = 0;

        while (i < str.length())
        {
            temp[i] = str.charAt(i);
            i++;
        }

        while (i < size)
        {
            temp[i] = padChar;
            i++;
        }

        str = new String(temp);
    }

    return str;
}

the formatter solution is not optimal. just building the format string creates 2 new strings.

apache's solution can be improved by initializing the sb with the target size so replacing below

StringBuffer padded = new StringBuffer(str); 

with

StringBuffer padded = new StringBuffer(pad); 
padded.append(value);

would prevent the sb's internal buffer from growing.

Your solution is ok. only try it in this way:

files=$(grep -rl oldstr path) && echo $files | xargs sed....

so execute the xargs only when grep return 0, e.g. when found the string in some files.

I faced the same problem. Initially I deleted the .bash_profile but this is not the right way. After installing anaconda it is showing the instructions clearly for this problem. Please check the image for solution provided by Anaconda

In VB2008, it works this way:

Project>Add References

Then click on the Recent tab where you can see list of references used recently. Locate the one you do not want and delet it. Then you close without adding anything.

I as well as you faced a problem of work angular.copy and angular.expect because they do not copy the object or create the object without adding some dependencies. My solution was this:

  copyFactory = (() ->
    resource = ->
      resource.__super__.constructor.apply this, arguments
      return
    this.extendTo resource
    resource
  ).call(factory)

You can use wait:

some_command &
P1=$!
other_command &
P2=$!
wait $P1 $P2

It assigns the background program PIDs to variables ($! is the last launched process' PID), then the wait command waits for them. It is nice because if you kill the script, it kills the processes too!

Updated Answer (2020)

You can get last N records simply by using last method:

Record.last(N)

Example:

User.last(5)

Returns 5 users in descending order by their id.

Deprecated (Old Answer)

An active record query like this I think would get you what you want ('Something' is the model name):

Something.find(:all, :order => "id desc", :limit => 5).reverse

edit: As noted in the comments, another way:

result = Something.find(:all, :order => "id desc", :limit => 5)

while !result.empty?
        puts result.pop
end

This question has been answered but I feel I should also mention another potential cause. This is a direct result of coming across the same error message but for different reasons. If your list/s are empty the operation will not be performed. check your code for indents and typos

When nesting repetition operators, make absolutely sure that there is only one way to match the same match.

The accepted answer here is the most correct for the given scenario.

It made me wonder though about simply inverting a boolean value in general. It turns out the accepted solution here works as one liner, and there's another one-liner that works as well. Assuming you have a variable "n" that you know is a boolean, the easiest ways to invert it are:

n = n is False

which was my original solution, and then the accepted answer from this question:

n = not n

The latter IS more clear, but I wondered about performance and hucked it through timeit - and it turns out at n = not n is also the FASTER way to invert the boolean value.

If you're having trouble with this setting and it seems to work sometimes and not other times - consider if the times where it doesn't work are during unit tests.

Many people declare custom test-time properties via the @TestPropertySources annotation declared somewhere in your test inheritance hierarchy. This will override whatever you put in your application.properties or other production properties settings so those values you're setting are effectively being ignored at test-time.

Though an old question, I would like to add that currently mock library (backport of unittest.mock) supports assert_not_called method.

Just upgrade yours;

pip install mock --upgrade

You can do it this way to return you a list of absolute path files.

def list_files_recursive(path):
    """
    Function that receives as a parameter a directory path
    :return list_: File List and Its Absolute Paths
    """

    import os

    files = []

    # r = root, d = directories, f = files
    for r, d, f in os.walk(path):
        for file in f:
            files.append(os.path.join(r, file))

    lst = [file for file in files]
    return lst


if __name__ == '__main__':

    result = list_files_recursive('/tmp')
    print(result)

Here you go

var yourString = "/installers/";_x000D_
var result = yourString.substring(1, yourString.length-1);_x000D_
_x000D_
console.log(result);

Or you can use .slice as suggested by Ankit Gupta

var yourString = "/installers/services/";_x000D_
_x000D_
var result = yourString.slice(1,-1);_x000D_
_x000D_
console.log(result);

Documentation for the slice and substring.

Public Sub UpdateMyFunctions()
    Dim myRange As Range
    Dim rng As Range

    'Considering The Functions are in Range A1:B10
    Set myRange = ActiveSheet.Range("A1:B10")

    For Each rng In myRange
        rng.Formula = rng.Formula
    Next
End Sub

You can also just use the top command and your user ID will indicate the jobs running and the their times.

$ top

(this will show all running jobs)

$ top -U [user ID]

(This will show jobs that are specific for the user ID)

SDK developers prefer to define their own types using typedef. This allows changing underlying types only in one place, without changing all client code. It is important to follow this convention. DWORD is unlikely to be changed, but types like DWORD_PTR are different on different platforms, like Win32 and x64. So, if some function has DWORD parameter, use DWORD and not unsigned int, and your code will be compiled in all future windows headers versions.

Stop installing android studio 3.0.1 and go back 2.3.3 ( Stable version) . Check for the stable version and you can find them a lot

All you have to do uninstall and go back to the other version. Yes it asks to create gradle file seperately which is completely new to me!

Failure is the stepping stone for success..

The curl installed by default in Debian supports HTTPS since a great while back. (a long time ago there were two separate packages, one with and one without SSL but that's not the case anymore)

OPTIONS /path

You can send an OPTIONS request with curl like this:

curl -i -X OPTIONS http://example.org/path

You may also use -v instead of -i to see more output.

OPTIONS *

To send a plain * (instead of the path, see RFC 7231) with the OPTIONS method, you need curl 7.55.0 or later as then you can run a command line like:

curl -i --request-target "*" -X OPTIONS http://example.org

You can use .empty(), like this:

$("#foo").empty();

From the docs:

Remove all child nodes of the set of matched elements from the DOM.

As the documentation says, this method call returns "a pseudorandom, uniformly distributed int value between 0 (inclusive) and the specified value (exclusive)". This means that you will get numbers from 0 to 9 in your case. So you've done everything correctly by adding one to that number.

Generally speaking, if you need to generate numbers from min to max (including both), you write

random.nextInt(max - min + 1) + min

Bootstrap 3:

Why fight it? Why not simply control your table width using the bootstrap grid?

<div class="row">
    <div class="col-sm-6">
        <table></table>
    </div>
</div>

This will create a table that is half (6 out of 12) of the width of the containing element.

I sometimes use inline styles as per the other answers, but it is discouraged.

Bootstrap 4:

Bootstrap 4 has some nice helper classes for width like w-25, w-50, w-75, w-100, and w-auto. This will make the table 50% width:

<table class="w-50"></table>

Here's the doc: https://getbootstrap.com/docs/4.0/utilities/sizing/

It looks like you would do something like this:

boost::shared_mutex _access;
void reader()
{
  // get shared access
  boost::shared_lock<boost::shared_mutex> lock(_access);

  // now we have shared access
}

void writer()
{
  // get upgradable access
  boost::upgrade_lock<boost::shared_mutex> lock(_access);

  // get exclusive access
  boost::upgrade_to_unique_lock<boost::shared_mutex> uniqueLock(lock);
  // now we have exclusive access
}

You can get your answer fairly easily for the iPhone5 along with other smartphones on the media feature database for mobile devices:

You can even get your own device values on the test page on the same website.

Just read it in to MATLAB in one block

fid = fopen('file.csv');
data=textscan(fid,'%s %f %f','delimiter',',');
fclose(fid);

You can then process it using logical addressing

ind50 = data{2}>=50 ;

ind50 is then an index of the rows where column 2 is greater than 50. So

data{1}(ind50)

will list all the strings for the rows of interest. Then just use fprintf to write out your data to the new file

If you need to write semantically correct mark-up, even in HTML5, you must not use ' to escape single quotes. Although, I can imagine you actually meant apostrophe rather then single quote.

single quotes and apostrophes are not the same, semantically, although they might look the same.

Here's one apostrophe.

Use ' to insert it if you need HTML4 support. (edited)

In British English, single quotes are used like this:

"He told me to 'give it a try'", I said.

Quotes come in pairs. You can use:

<p><q>He told me to <q>give it a try</q></q>, I said.<p>

to have nested quotes in a semantically correct way, deferring the substitution of the actual characters to the rendering engine. This substitution can then be affected by CSS rules, like:

q {
  quotes: '"' '"' '<' '>';
} 

An old but seemingly still relevant article about semantically correct mark-up: The Trouble With EM ’n EN (and Other Shady Characters).

(edited) This used to be:

Use ’ to insert it if you need HTML4 support.

But, as @James_pic pointed out, that is not the straight single quote, but the "Single curved quote, right".

If you use instanceof, making your equals implementation final will preserve the symmetry contract of the method: x.equals(y) == y.equals(x). If final seems restrictive, carefully examine your notion of object equivalence to make sure that your overriding implementations fully maintain the contract established by the Object class.

Of course! jQuery is just a library that utilizes javascript after all.

You can use document.getElementById to get the element in question, then change its height accordingly, through element.style.height.

elementToChange = document.getElementById('collapseableEl');
elementToChange.style.height = '100%';

Wrap that up in a neat little function that caters for toggling back and forth and you have yourself a solution.

fileinput is quite straightforward as mentioned on previous answers:

import fileinput

def replace_in_file(file_path, search_text, new_text):
    with fileinput.input(file_path, inplace=True) as f:
        for line in f:
            new_line = line.replace(search_text, new_text)
            print(new_line, end='')

Explanation:

• fileinput can accept multiple files, but I prefer to close each single file as soon as it is being processed. So placed single file_path in with statement.
• print statement does not print anything when inplace=True, because STDOUT is being forwarded to the original file.
• end='' in print statement is to eliminate intermediate blank new lines.

Can be used as follows:

file_path = '/path/to/my/file'
replace_in_file(file_path, 'old-text', 'new-text')

strInputString = strInputString.replace(/'/g, "''");

Hey there's a useful tutorial on Dot Net pearls: http://www.dotnetperls.com/progressbar

In agreement with Peter, you need to use some amount of threading or the program will just hang, somewhat defeating the purpose.

Example that uses ProgressBar and BackgroundWorker: C#

using System.ComponentModel;
using System.Threading;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, System.EventArgs e)
        {
            // Start the BackgroundWorker.
            backgroundWorker1.RunWorkerAsync();
        }

        private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
        {
            for (int i = 1; i <= 100; i++)
            {
                // Wait 100 milliseconds.
                Thread.Sleep(100);
                // Report progress.
                backgroundWorker1.ReportProgress(i);
            }
        }

        private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e)
        {
            // Change the value of the ProgressBar to the BackgroundWorker progress.
            progressBar1.Value = e.ProgressPercentage;
            // Set the text.
            this.Text = e.ProgressPercentage.ToString();
        }
    }
} //closing here

if not myList:
  print "Nothing here"

If you are getting the following error while connecting the mysql (either local or mysql container running the mysql):

java.sql.SQLNonTransientConnectionException: Public Key Retrieval is not allowed

Solution: Add the following line in your database service:

command: --default-authentication-plugin=mysql_native_password

You could do $stmt->queryString to obtain the SQL query used in the statement. If you want to save the entire $stmt variable (I can't see why), you could just copy it. It is an instance of PDOStatement so there is apparently no advantage in storing it.
