var top = ($(".apps_intro_wrapper_inner").offset() || { "top": NaN }).top;   
if (!isNaN(top)) {
$("#app_scroler").click(function () {   
$('html, body').animate({
            scrollTop: top
        }, 100);
    });
}

if you want to scroll a little above or below from specific div that add value to the top like this.....like I add 800

var top = ($(".apps_intro_wrapper_inner").offset() || { "top": NaN }).top + 800;

First, you need to understand the difference between window and document. The window object is a top level client side object. There is nothing above the window object. JavaScript is an object orientated language. You start with an object and apply methods to its properties or the properties of its object groups. For example, the document object is an object of the window object. To change the document's background color, you'd set the document's bgcolor property.

window.document.bgcolor = "red" 

To answer your question, There is no difference in the end result between window and document scrollTop. Both will give the same output.

Check working example at http://jsfiddle.net/7VRvj/6/

In general use document mainly to register events and use window to do things like scroll, scrollTop, and resize.

just add

window.scrollTo({ top: 0);

to ngOnInit()

Here is a function that will do it without jQuery:

function getElementOffset(element)
{
    var de = document.documentElement;
    var box = element.getBoundingClientRect();
    var top = box.top + window.pageYOffset - de.clientTop;
    var left = box.left + window.pageXOffset - de.clientLeft;
    return { top: top, left: left };
}

Here is what you can do using jquery:

$('#A_ID').click(function (e) { //#A_ID is an example. Use the id of your Anchor
    $('html, body').animate({
        scrollTop: $('#DIV_ID').offset().top - 20 //#DIV_ID is an example. Use the id of your destination on the page
    }, 'slow');
});

Simple solution:

scrolling to any element by ID or NAME:

SmoothScrollTo("#elementId", 1000);

code:

function SmoothScrollTo(id_or_Name, timelength){
    var timelength = timelength || 1000;
    $('html, body').animate({
        scrollTop: $(id_or_Name).offset().top-70
    }, timelength, function(){
        window.location.hash = id_or_Name;
    });
}

I tried the above answer. However, none of the solutiond worked for me. I changed the emulator to USB and the code is running on the USB target device prefectly!

Please refer below Ajax overview:

http://msdn.microsoft.com/en-us/library/bb386454.aspx

In a php section before the HTML section, use sprinf() to create a constant string from the variables:

$mystuff = sprinf("My name is %s and my mother's name is %s","Suzy","Caroline");

Then in the HTML section you can do whatever you like, such as:

<p>$mystuff</p> 

Best way work for me

<img src="/path/image.png" />// this work only online
    or
    <img src="../../path/image.png" /> // this work both
    or asign variable
    <?php 
    $base_url = '';
    if($_SERVER['HTTP_HOST'] == 'localhost')
    {
         $base_url = 'localpath'; 
    }
    ?>
    <img src="<?php echo $base_url;?>/path/image.png" /> 

Install the readr package, then use library(readr).

Also you are able to add multiple buttons using rightBarButtonItems

-(void)viewDidLoad{

    UIBarButtonItem *button1 = [[UIBarButtonItem alloc] initWithTitle:@"button 1" style:UIBarButtonItemStylePlain target:self action:@selector(YOUR_METHOD1:)];
    UIBarButtonItem *button2 = [[UIBarButtonItem alloc] initWithTitle:@"button 2" style:UIBarButtonItemStylePlain target:self action:@selector(YOUR_METHOD2:)];

    self.navigationItem.rightBarButtonItems = @[button1, button2];
}

I had this same problem and I was able to solve it by implementing the IValidatableObject interface in my view model.

public class RegisterViewModel : IValidatableObject
{
    /// <summary>
    /// Error message for Minimum password
    /// </summary>
    public static string PasswordLengthErrorMessage => $"The password must be at least {PasswordMinimumLength} characters";

    /// <summary>
    /// Minimum acceptable password length
    /// </summary>
    public const int PasswordMinimumLength = 8;

    /// <summary>
    /// Gets or sets the password provided by the user.
    /// </summary>
    [Required]
    [DataType(DataType.Password)]
    [Display(Name = "Password")]
    public string Password { get; set; }

    /// <summary>
    /// Only need to validate the minimum length
    /// </summary>
    /// <param name="validationContext">ValidationContext, ignored</param>
    /// <returns>List of validation errors</returns>
    public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
    {
        var errorList = new List<ValidationResult>();
        if ((Password?.Length ?? 0 ) < PasswordMinimumLength)
        {
            errorList.Add(new ValidationResult(PasswordLengthErrorMessage, new List<string>() {"Password"}));
        }
        return errorList;
    }
}

The markup in the Razor is then...

<div class="form-group">
    @Html.LabelFor(m => m.Password)
    @Html.PasswordFor(m => m.Password, new { @class = "form-control input-lg" }
    <div class="password-helper">Must contain: 8 characters, 1 upper-case, 1 lower-case
    </div>
    @Html.ValidationMessagesFor(m => m.Password, new { @class = "text-danger" })
</div>

This works really well. If I attempt to use [StringLength] instead then the rendered HTML is just not correct. The validation should render as:

<span class="text-danger field-validation-invalid field-validation-error" data-valmsg-for="Password" data-valmsg-replace="true"><span id="Password-error" class="">The Password should be a minimum of 8 characters long.</span></span>

With the StringLengthAttribute the rendered HTML shows as a ValidationSummary which is not correct. The funny thing is that when the validator fails the submit is still blocked!

Win7, version 10 location:

C:\Program Files\PostgreSQL\10\postgresql.conf

Omit the "~\":

var path = @"FolderIcon\Folder.ico";

~\ doesn't mean anything in terms of the file system. The only place I've seen that correctly used is in a web app, where ASP.NET replaces the tilde with the absolute path to the root of the application.

You can typically assume the paths are relative to the folder where the EXE is located. Also, make sure that the image is specified as "content" and "copy if newer"/"copy always" in the properties tab in Visual Studio.

This way:

<script type="text/javascript">
    function yourFunction(element) {
        alert(element);
    }
</script>
<input id="myinput" onblur="yourFunction(this)">

Or if you attach the listener via JavaScript (jQuery in this example):

var input = $('#myinput').blur(function() {
    alert(this);
});

Edit: sorry. I misread the question.

library(caret)
intrain<-createDataPartition(y=sub_train$classe,p=0.7,list=FALSE)
training<-m_train[intrain,]
testing<-m_train[-intrain,]

I faced the same error, upon checking I had a developer access and couldn't publish a new branch. Adding higher access rights resolved this issue.(Gitlab)

Change column position:

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

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

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

You can do it like this:

alert(parseFloat("1.1531531414")); // alerts the float
parseFloat = function(input) { return 1; };
alert(parseFloat("1.1531531414")); // alerts '1'

 You Can Get UIColor From String Code Like
   circularSpinner.fillColor = [self getUIColorObjectFromHexString:@"27b8c8" alpha:9];

 //Function For Hex Color Use
    - (unsigned int)intFromHexString:(NSString *)hexStr
    {
        unsigned int hexInt = 0;

        // Create scanner
        NSScanner *scanner = [NSScanner scannerWithString:hexStr];

        // Tell scanner to skip the # character
        [scanner setCharactersToBeSkipped:[NSCharacterSet characterSetWithCharactersInString:@"#"]];

        // Scan hex value
        [scanner scanHexInt:&hexInt];

        return hexInt;
    }




    - (UIColor *)getUIColorObjectFromHexString:(NSString *)hexStr alpha:(CGFloat)alpha
    {
        // Convert hex string to an integer
        unsigned int hexint = [self intFromHexString:hexStr];

        // Create color object, specifying alpha as well
        UIColor *color =
        [UIColor colorWithRed:((CGFloat) ((hexint & 0xFF0000) >> 16))/255
                        green:((CGFloat) ((hexint & 0xFF00) >> 8))/255
                         blue:((CGFloat) (hexint & 0xFF))/255
                        alpha:alpha];

        return color;
    }

    /Function For Hex Color Use

I have written on this property framework for the last year. It will provide of multiple ways to load properties, and have them strongly typed as well.

Have a look at http://sourceforge.net/projects/jhpropertiestyp/

JHPropertiesTyped will give the developer strongly typed properties. Easy to integrate in existing projects. Handled by a large series for property types. Gives the ability to one-line initialize properties via property IO implementations. Gives the developer the ability to create own property types and property io's. Web demo is also available, screenshots shown above. Also have a standard implementation for a web front end to manage properties, if you choose to use it.

Complete documentation, tutorial, javadoc, faq etc is a available on the project webpage.

I don't like absolute positioning, either, because there is almost always some collateral damage, i.e. unintended side effects. Especially when you are working with a responsive design. There seems to be an alternative - the sandbag technique. By inserting a "helper" element, either in the markup of via CSS, we can push elements down to the bottom of the container. See http://community.sitepoint.com/t/css-floating-divs-to-the-bottom-inside-a-div/20932 for examples.

The solution is to add this to the beginning of your .htaccess

<Files wp-login.php>
Order Deny,Allow
Deny from all
Allow from all
</Files>

It's because many hosts were under attack, using the wordpress from their clients.

Also you can add #include<vector> in the header. When two of the above solutions don't work.

for small arrays this may work.

int getOrder (double num, double[] array){
    double[] b = new double[array.length];
    for (int i = 0; i < array.length; i++){
        b[i] = array[i];
    }
    Arrays.sort(b);
    for (int i = 0; i < b.length; i++){
        if ( num < b[i]) return i;
    }
    return b.length;
}

I was surprised that the initial loading of array b was necessary

double[] b = array; // makes b point to array. so beware!

This does not want to be a "just-use-a-library" answer but just in case you're using Lodash you can use .clamp:

_.clamp(yourInput, lowerBound, upperBound);

So that:

_.clamp(22, -10, 10); // => 10

Here is its implementation, taken from Lodash source:

/**
 * The base implementation of `_.clamp` which doesn't coerce arguments.
 *
 * @private
 * @param {number} number The number to clamp.
 * @param {number} [lower] The lower bound.
 * @param {number} upper The upper bound.
 * @returns {number} Returns the clamped number.
 */
function baseClamp(number, lower, upper) {
  if (number === number) {
    if (upper !== undefined) {
      number = number <= upper ? number : upper;
    }
    if (lower !== undefined) {
      number = number >= lower ? number : lower;
    }
  }
  return number;
}

Also, it's worth noting that Lodash makes single methods available as standalone modules, so in case you need only this method, you can install it without the rest of the library:

npm i --save lodash.clamp

Variables declared inside a function are local to that function. For instance:

foo <- function() {
    bar <- 1
}
foo()
bar

gives the following error: Error: object 'bar' not found.

If you want to make bar a global variable, you should do:

foo <- function() {
    bar <<- 1
}
foo()
bar

In this case bar is accessible from outside the function.

However, unlike C, C++ or many other languages, brackets do not determine the scope of variables. For instance, in the following code snippet:

if (x > 10) {
    y <- 0
}
else {
    y <- 1
}

y remains accessible after the if-else statement.

As you well say, you can also create nested environments. You can have a look at these two links for understanding how to use them:

1. http://stat.ethz.ch/R-manual/R-devel/library/base/html/environment.html
2. http://stat.ethz.ch/R-manual/R-devel/library/base/html/get.html

Here you have a small example:

test.env <- new.env()

assign('var', 100, envir=test.env)
# or simply
test.env$var <- 100

get('var') # var cannot be found since it is not defined in this environment
get('var', envir=test.env) # now it can be found

The whole idea of a keytool is to sign your apk with a unique identifier indicating the source of that apk. A keystore file (from what I understand) is used for debuging so your apk has the functionality of a keytool without signing your apk for production. So yes, for debugging purposes you should be able to sign multiple apk's with a single keystore. But understand that, upon pushing to production you'll need unique keytools as identifiers for each apk you create.

    success = True
    while success:
      success,image = vidcap.read()
      print ('Read a new frame: ', success)
      cv2.imwrite( pathOut + "\\frame%d.jpg" % count, image)     # save frame as JPEG file
      count += 1

    args = a.parse_args()
    print(args)
    extractImages(args.pathIn, args.pathOut)

Multiply the input by Math.PI/180 to convert from degrees to radians before calling the system trig functions.

You could also define your own functions:

function sinDegrees(angleDegrees) {
    return Math.sin(angleDegrees*Math.PI/180);
};

and so on.

This works Fine

SELECT * FROM information_schema.tables;

Either make your friends download the runtime DLL (@Kay's answer), or compile the app with static linking.

In visual studio, go to Project tab -> properties - > configuration properties -> C/C++ -> Code Generation on runtime library choose /MTd for debug mode and /MT for release mode.

This will cause the compiler to embed the runtime into the app. The executable will be significantly bigger, but it will run without any need of runtime dlls.

Type in console as root:

apt-get update && apt-get install php5-curl

or with sudo:

sudo apt-get update && sudo apt-get install php5-curl

1st, check your DNS config and if you can ping any host at all,

ping google.com
ping zm.archive.ubuntu.com

If it does not work, check /etc/resolv.conf or /etc/network/resolv.conf, if not, change your apt-source to a different one.

/etc/apt/sources.list

There are several ways. One way is to use save() to save the exact object. e.g. for data frame foo:

save(foo,file="data.Rda")

Then load it with:

load("data.Rda")

You could also use write.table() or something like that to save the table in plain text, or dput() to obtain R code to reproduce the table.

I've found a way to do this without subclassing UICollectionView, just calculating the contentOffset in horizontal. Obviously without isPagingEnabled set true. Here is the code:

var offsetScroll1 : CGFloat = 0
var offsetScroll2 : CGFloat = 0
let flowLayout = UICollectionViewFlowLayout()
let screenSize : CGSize = UIScreen.main.bounds.size
var items = ["1", "2", "3", "4", "5"]

override func viewDidLoad() {
    super.viewDidLoad()
    flowLayout.scrollDirection = .horizontal
    flowLayout.minimumLineSpacing = 7
    let collectionView = UICollectionView(frame: CGRect(x: 0, y: 590, width: screenSize.width, height: 200), collectionViewLayout: flowLayout)
    collectionView.register(collectionViewCell1.self, forCellWithReuseIdentifier: cellReuseIdentifier)
    collectionView.delegate = self
    collectionView.dataSource = self
    collectionView.backgroundColor = UIColor.clear
    collectionView.showsHorizontalScrollIndicator = false
    self.view.addSubview(collectionView)
}

func scrollViewWillBeginDragging(_ scrollView: UIScrollView) {
    offsetScroll1 = offsetScroll2
}

func scrollViewDidEndDragging(_ scrollView: UIScrollView, willDecelerate decelerate: Bool) {
    offsetScroll1 = offsetScroll2
}

func scrollViewWillEndDragging(_ scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>){
    let indexOfMajorCell = self.desiredIndex()
    let indexPath = IndexPath(row: indexOfMajorCell, section: 0)
    flowLayout.collectionView!.scrollToItem(at: indexPath, at: .centeredHorizontally, animated: true)
    targetContentOffset.pointee = scrollView.contentOffset
}

private func desiredIndex() -> Int {
    var integerIndex = 0
    print(flowLayout.collectionView!.contentOffset.x)
    offsetScroll2 = flowLayout.collectionView!.contentOffset.x
    if offsetScroll2 > offsetScroll1 {
        integerIndex += 1
        let offset = flowLayout.collectionView!.contentOffset.x / screenSize.width
        integerIndex = Int(round(offset))
        if integerIndex < (items.count - 1) {
            integerIndex += 1
        }
    }
    if offsetScroll2 < offsetScroll1 {
        let offset = flowLayout.collectionView!.contentOffset.x / screenSize.width
        integerIndex = Int(offset.rounded(.towardZero))
    }
    let targetIndex = integerIndex
    return targetIndex
}

Or you can do this if you wanted, just another option:

try {
    DB::connection()->pdo->beginTransaction();

    $photos = Photo::where('user_id', '=', $user_id)->delete(); // Delete all photos for user
    $user = Geofence::where('id', '=', $user_id)->delete(); // Delete users

    DB::connection()->pdo->commit();

}catch(\Laravel\Database\Exception $e) {
    DB::connection()->pdo->rollBack();
    Log::exception($e);
}

Note if you are not using the default laravel db connection then you need to do the following:

DB::connection('connection_name')->pdo->beginTransaction();
DB::connection('connection_name')->pdo->commit();
DB::connection('connection_name')->pdo->rollBack();

It is an old question but thought to leave this here. Most people are checking if the variable is {} meaning a key-value paired and not what is the underline construct that JavaScript is using for a given thing, cuz to be honest mostly everything in JavaScript is an object. So taking that out of the way. If you do...

let x = function() {}
typeof x === 'function' //true
x === Object(x) // true
x = []
x === Object(x) // true

// also
x = null
typeof null // 'object'

Most of the time what we want is to know if we have a resource object from an API or our database call returned from the ORM. We can then test if is not an Array, is not null, is not typeof 'function', and is an Object

// To account also for new Date() as @toddmo pointed out

x instanceof Object && x.constructor === Object

x = 'test' // false
x = 3 // false
x = 45.6 // false
x = undefiend // false
x = 'undefiend' // false
x = null // false
x = function(){} // false
x = [1, 2] // false
x = new Date() // false
x = {} // true

To my knowledge this is inherent to most widgets and the amount of "padding" differs among phone manufacturers. This padding is really white space between the image border and the image in the 9 patch image file.

For example on my Droid X, spinner widgets get extra white space than buttons, which makes it look awkward when you have a spinner inline with a button, yet on my wife's phone the same application doesn't have the same problem and looks great!

The only suggestion I would have is to create your own 9 patch files and use them in your application.

Ahhh the pains that are Android.

Edited: Clarify padding vs white space.

There are several problems.

One is of style; always capitalize class names. This is a universally observed Java convention. Failing to do so confuses other programmers.

Secondly, the line

System.out.println(boolean isLeapYear);

is a syntax error. Delete it.

Thirdly.

You never call the function from your main routine. That is why you never see any reply to the input.

Remember if your route is name-spaced, Like:

product GET  /products/:id(.:format)  spree/products#show

Then try :

helper.link_to("test", app.spree.product_path(Spree::Product.first), method: :get)

output

Spree::Product Load (0.4ms)  SELECT  "spree_products".* FROM "spree_products"  WHERE "spree_products"."deleted_at" IS NULL  ORDER BY "spree_products"."id" ASC LIMIT 1
=> "<a data-method=\"get\" href=\"/products/this-is-the-title\">test</a>" 

This actually worked for me:

private String uri2filename() {

    String ret;
    String scheme = uri.getScheme();

    if (scheme.equals("file")) {
        ret = uri.getLastPathSegment();
    }
    else if (scheme.equals("content")) {
        Cursor cursor = getContentResolver().query(uri, null, null, null, null);
        if (cursor != null && cursor.moveToFirst()) {
            ret = cursor.getString(cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME));
        }
   }
   return ret;
}

Remove the spaces around your =:

<div>    
  <input type="text" [(ngModel)]="str" name="str">
</div>

But you need to have the variable named str on back-end, than its should work fine.

Might also be interesting for you to know that you can use:

{r echo=FALSE, results='hide',message=FALSE}
a<-as.numeric(rnorm(100))
hist(a, breaks=24)

to exclude all the commands you give, all the results it spits out and all message info being spit out by R (eg. after library(ggplot) or something)

IMG Method

If you want the image to be a stand alone element, use this CSS:

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

With this HTML:

<img src='folder/image.gif' id='selector'/>

Fiddle

Please note that the img tag would have to be inside the body tag ONLY. If it were inside anything else, it may not fill the entire screen based on the other elements properties. This method will also not work if the page is taller than the image. It will leave white space. This is where the background method comes in

Background Image Method

If you want it to be the background image of you page, you can use this CSS:

body {
    background-image:url('folder/image.gif');
    background-size:100%;
    background-repeat: repeat-y;
    background-attachment: fixed;
    height:100%;
    width:100%;
}

Fiddle

Or the shorthand version:

body {
    background:url('folder/image.gif') repeat-y 100% 100% fixed;
    height:100%;
    width:100%;
}

Fiddle

1. General -> Signing -> check automatically manage signing and select team

2. Build settings -> Signing -> Code Signing Identity -> SET ALL TO "IOS developer"

You can also map the share to a local drive as follows:

net use X: "\\servername\share" /user:morgan password

You can try checking some of the class generators online for further information. However, I believe some of the answers have been useful. Here's my approach that may be useful.

The following code was made with a dynamic method in mind.

dynObj = (JArray) JsonConvert.DeserializeObject(nvm);

foreach(JObject item in dynObj) {
 foreach(JObject trend in item["trends"]) {
  Console.WriteLine("{0}-{1}-{2}", trend["query"], trend["name"], trend["url"]);
 }
}

This code basically allows you to access members contained in the Json string. Just a different way without the need of the classes. query, trend and url are the objects contained in the Json string.

You can also use this website. Don't trust the classes a 100% but you get the idea.

As you said, in MySQL USAGE is synonymous with "no privileges". From the MySQL Reference Manual:

The USAGE privilege specifier stands for "no privileges." It is used at the global level with GRANT to modify account attributes such as resource limits or SSL characteristics without affecting existing account privileges.

USAGE is a way to tell MySQL that an account exists without conferring any real privileges to that account. They merely have permission to use the MySQL server, hence USAGE. It corresponds to a row in the `mysql`.`user` table with no privileges set.

The IDENTIFIED BY clause indicates that a password is set for that user. How do we know a user is who they say they are? They identify themselves by sending the correct password for their account.

A user's password is one of those global level account attributes that isn't tied to a specific database or table. It also lives in the `mysql`.`user` table. If the user does not have any other privileges ON *.*, they are granted USAGE ON *.* and their password hash is displayed there. This is often a side effect of a CREATE USER statement. When a user is created in that way, they initially have no privileges so they are merely granted USAGE.

Start with looking up the z-value for your desired confidence interval from a look-up table. The confidence interval is then mean +/- z*sigma, where sigma is the estimated standard deviation of your sample mean, given by sigma = s / sqrt(n), where s is the standard deviation computed from your sample data and n is your sample size.

You can flush hosts local MySQL using following command:

mysqladmin -u [username] -p flush-hosts
**** [MySQL password]

or

mysqladmin flush-hosts -u [username] -p
**** [MySQL password]

Though Amazon RDS database server is on network then use the following command as like as flush network MySQL server:

mysqladmin -h <RDS ENDPOINT URL> -P <PORT> -u <USER> -p flush-hosts
mysqladmin -h [YOUR RDS END POINT URL] -P 3306 -u [DB USER] -p flush-hosts 

In additional suggestion you can permanently solve blocked of many connections error problem by editing my.ini file[Mysql configuration file]

change variables max_connections = 10000;

or

login into MySQL using command line -

mysql -u [username] -p
**** [MySQL password]

put the below command into MySQL window

SET GLOBAL max_connect_errors=10000;
set global max_connections = 200;

check veritable using command-

show variables like "max_connections";
show variables like "max_connect_errors";

I'm sticking to the shared local data solution mentioned in the question using localStorage. It seems to be the best solution in terms of reliability, performance, and browser compatibility.

localStorage is implemented in all modern browsers.

The storage event fires when other tabs makes changes to localStorage. This is quite handy for communication purposes.

They are both the same functionally but the .min one has all unnecessary characters removed in order to make the file size smaller.

Just to point out as well, you are better using the minified version (.min) for your live environment as Google are now checking on page loading times. Having all your JS file minified means they will load faster and will score you more brownie points.

You can get an addon for Mozilla called Page Speed that will look through your site and show you all the .JS files and provide minified versions (amongst other things).

According to spark documentation "where() is an alias for filter()"

filter(condition) Filters rows using the given condition. where() is an alias for filter().

Parameters: condition – a Column of types.BooleanType or a string of SQL expression.

>>> df.filter(df.age > 3).collect()
[Row(age=5, name=u'Bob')]
>>> df.where(df.age == 2).collect()
[Row(age=2, name=u'Alice')]

>>> df.filter("age > 3").collect()
[Row(age=5, name=u'Bob')]
>>> df.where("age = 2").collect()
[Row(age=2, name=u'Alice')]

As far as I know, the order of the repositories in your pom.xml will also decide the order of the repository access.

As for configuring repositories in settings.xml, I've read that the order of repositories is interestingly enough the inverse order of how the repositories will be accessed.

I use a personnal blend of the phantomjs waitfor.js example.

This is my main.js file:

'use strict';

var wasSuccessful = phantom.injectJs('./lib/waitFor.js');
var page = require('webpage').create();

page.open('http://foo.com', function(status) {
  if (status === 'success') {
    page.includeJs('https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/jquery.min.js', function() {
      waitFor(function() {
        return page.evaluate(function() {
          if ('complete' === document.readyState) {
            return true;
          }

          return false;
        });
      }, function() {
        var fooText = page.evaluate(function() {
          return $('#foo').text();
        });

        phantom.exit();
      });
    });
  } else {
    console.log('error');
    phantom.exit(1);
  }
});

And the lib/waitFor.js file (which is just a copy and paste of the waifFor() function from the phantomjs waitfor.js example):

function waitFor(testFx, onReady, timeOutMillis) {
    var maxtimeOutMillis = timeOutMillis ? timeOutMillis : 3000, //< Default Max Timout is 3s
        start = new Date().getTime(),
        condition = false,
        interval = setInterval(function() {
            if ( (new Date().getTime() - start < maxtimeOutMillis) && !condition ) {
                // If not time-out yet and condition not yet fulfilled
                condition = (typeof(testFx) === "string" ? eval(testFx) : testFx()); //< defensive code
            } else {
                if(!condition) {
                    // If condition still not fulfilled (timeout but condition is 'false')
                    console.log("'waitFor()' timeout");
                    phantom.exit(1);
                } else {
                    // Condition fulfilled (timeout and/or condition is 'true')
                    // console.log("'waitFor()' finished in " + (new Date().getTime() - start) + "ms.");
                    typeof(onReady) === "string" ? eval(onReady) : onReady(); //< Do what it's supposed to do once the condi>
                    clearInterval(interval); //< Stop this interval
                }
            }
        }, 250); //< repeat check every 250ms
}

This method is not asynchronous but at least am I assured that all the resources were loaded before I try using them.

the wmic bios get serialnumber command call the Win32_BIOS wmi class and get the value of the SerialNumber property, which retrieves the serial number of the BIOS Chip of your system.

I would change your binding to be:

<button type="button" value="click me" onclick="check_me" />

I would then change your check_me() function declaration to be:

function check_me() {   
  //event.preventDefault();
  var hello = document.myForm.username.value;
  var err = '';

  if(hello == '' || hello == null) {
    err = 'User name required';
  }

  if(err != '') { 
     alert(err); 
     $('username').focus(); 
     event.preventDefault(); 
   } else { 
    return true; }
}

Alternatively you can create such a function:

function implode_with_quotes(array $data)
{
    return sprintf("'%s'", implode("', '", $data));
}

In addition to the answers above.

I wrote following test.exe as console application

static void Main(string[] args) {
  Console.WriteLine(
    System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName);
  Console.WriteLine(
    System.Reflection.Assembly.GetEntryAssembly().Location);
  Console.WriteLine(
    System.Reflection.Assembly.GetExecutingAssembly().Location);
  Console.WriteLine(
    System.Reflection.Assembly.GetCallingAssembly().Location);
}

Then I compiled the project and renamed its output to the test2.exe file. The output lines were correct and the same.

But, if I start it in the Visual Studio, the result is:

d:\test2.vhost.exe

d:\test2.exe

d:\test2.exe

C:\Windows\Microsoft.NET\Framework\v2.0.50727\mscorlib.dll

The ReSharper plug-in to the Visual Studio has underlined the

System.Diagnostics.Process.GetCurrentProcess().MainModule

as possible System.NullReferenceException. If you look into documentation of the MainModule you will find that this property can throw also NotSupportedException, PlatformNotSupportedException and InvalidOperationException.

The GetEntryAssembly method is also not 100% "safe". MSDN:

The GetEntryAssembly method can return null when a managed assembly has been loaded from an unmanaged application. For example, if an unmanaged application creates an instance of a COM component written in C#, a call to the GetEntryAssembly method from the C# component returns null, because the entry point for the process was unmanaged code rather than a managed assembly.

For my solutions, I prefer the Assembly.GetEntryAssembly().Location.

More interest is if need to solve the problem for the virtualization. For example, we have a project, where we use a Xenocode Postbuild to link the .net code into one executable. This executable must be renamed. So all the methods above didn't work, because they only gets the information for the original assembly or inner process.

The only solution I found is

var location = System.Reflection.Assembly.GetEntryAssembly().Location;
var directory = System.IO.Path.GetDirectoryName(location);
var file = System.IO.Path.Combine(directory, 
  System.Diagnostics.Process.GetCurrentProcess().ProcessName + ".exe");

With IIS's self-signed certificate feature, you cannot set the common name (CN) for the certificate, and therefore cannot create a certificate bound to your choice of subdomain.

One way around the problem is to use makecert.exe, which is bundled with the .Net 2.0 SDK. On my server it's at:

C:\Program Files\Microsoft.Net\SDK\v2.0 64bit\Bin\makecert.exe

You can create a signing authority and store it in the LocalMachine certificates repository as follows (these commands must be run from an Administrator account or within an elevated command prompt):

makecert.exe -n "CN=My Company Development Root CA,O=My Company,
 OU=Development,L=Wallkill,S=NY,C=US" -pe -ss Root -sr LocalMachine
 -sky exchange -m 120 -a sha1 -len 2048 -r

You can then create a certificate bound to your subdomain and signed by your new authority:

(Note that the the value of the -in parameter must be the same as the CN value used to generate your authority above.)

makecert.exe -n "CN=subdomain.example.com" -pe -ss My -sr LocalMachine
 -sky exchange -m 120 -in "My Company Development Root CA" -is Root
 -ir LocalMachine -a sha1 -eku 1.3.6.1.5.5.7.3.1

Your certificate should then appear in IIS Manager to be bound to your site as explained in Tom Hall's post.

All kudos for this solution to Mike O'Brien for his excellent blog post at http://www.mikeobrien.net/blog/creating-self-signed-wildcard

./bilet.sh: line 6: [: 7]: integer expression expected

Be careful with " "

./bilet.sh: line 9: [: missing `]'

This is because you need to have space between brackets like:

if [ "$age" -le 7 ] -o [ "$age" -ge 65 ]

look: added space, and no " "

You may also use the stringr package

library(dplyr)
library(stringr)
My.Data %>% filter(str_detect(x, '^G45'))

You may not use '^' (starts with) in this case, to obtain the results you need

=VLOOKUP(A2,IF(B1:B3="B",A1:C3,""),1,FALSE)

Ctrl+Shift+Enter to enter.

There are several of this same question (1, 2). One way of doing it is using canvas. Here's a working solution. Here you can see some working examples of using this library.

I just ran into this problem on a UICollectionView and the way that i solved it similar to the answer above but in a pure UICollectionView way.

1. Create a custom UICollectionViewCell that contains whatever you will be filling it with to make it dynamic. I created its own .xib for it as it seems like the easiest approach.

2. Add constraints in that .xib that allow for the cell to be calculated from top to bottom. The re-sizing won't work if you haven't accounted for all of the height. Say you have a view on top, then a label underneath it, and another label underneath that. You would need to connect constraints to the top of the cell to the top of that view, then the bottom of the view to the top of the first label, bottom of first label to the top of the second label, and bottom of second label to bottom of cell.

3. Load the .xib into the viewcontroller and register it with the collectionView on viewDidLoad

   let nib = UINib(nibName: CustomCellName, bundle: nil)
   self.collectionView!.registerNib(nib, forCellWithReuseIdentifier: "customCellID")`
   

4. Load a second copy of that xib into the class and store it as a property so you can use it to determine the size of what that cell should be

   let sizingNibNew = NSBundle.mainBundle().loadNibNamed(CustomCellName, owner: CustomCellName.self, options: nil) as NSArray
   self.sizingNibNew = (sizingNibNew.objectAtIndex(0) as? CustomViewCell)!
   

5. Implement the UICollectionViewFlowLayoutDelegate in your view controller. The method that matters is called sizeForItemAtIndexPath. Inside that method you will need to pull the data from the datasource that is associated with that cell from the indexPath. Then configure the sizingCell and call preferredLayoutSizeFittingSize. The method returns a CGSize which will consist of the width minus the content insets and the height that is returned from self.sizingCell.preferredLayoutSizeFittingSize(targetSize).

   override func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize {
       guard let data = datasourceArray?[indexPath.item] else {
           return CGSizeZero
       }
       let sectionInset = self.collectionView?.collectionViewLayout.sectionInset
       let widthToSubtract = sectionInset!.left + sectionInset!.right
   
       let requiredWidth = collectionView.bounds.size.width
   
   
       let targetSize = CGSize(width: requiredWidth, height: 0)
   
       sizingNibNew.configureCell(data as! CustomCellData, delegate: self)
       let adequateSize = self.sizingNibNew.preferredLayoutSizeFittingSize(targetSize)
       return CGSize(width: (self.collectionView?.bounds.width)! - widthToSubtract, height: adequateSize.height)
    }
   

6. In the class of the custom cell itself you will need to override awakeFromNib and tell the contentView that its size needs to be flexible

    override func awakeFromNib() {
       super.awakeFromNib()
       self.contentView.autoresizingMask = [UIViewAutoresizing.FlexibleHeight]
    }
   

7. In the custom cell override layoutSubviews

    override func layoutSubviews() {
      self.layoutIfNeeded()
     }
   

8. In the class of the custom cell implement preferredLayoutSizeFittingSize. This is where you will need to do any trickery on the items that are being laid out. If its a label you will need to tell it what its preferredMaxWidth should be.

   func preferredLayoutSizeFittingSize(_ targetSize: CGSize)-> CGSize {
   
       let originalFrame = self.frame
       let originalPreferredMaxLayoutWidth = self.label.preferredMaxLayoutWidth
   
   
       var frame = self.frame
       frame.size = targetSize
       self.frame = frame
   
       self.setNeedsLayout()
       self.layoutIfNeeded()
       self.label.preferredMaxLayoutWidth = self.questionLabel.bounds.size.width
   
   
       // calling this tells the cell to figure out a size for it based on the current items set
       let computedSize = self.systemLayoutSizeFittingSize(UILayoutFittingCompressedSize)
   
       let newSize = CGSize(width:targetSize.width, height:computedSize.height)
   
       self.frame = originalFrame
       self.questionLabel.preferredMaxLayoutWidth = originalPreferredMaxLayoutWidth
   
       return newSize
   }
   

All those steps should give you the correct sizes. If your getting 0 or other funky numbers than you haven't set up your constraints properly.

Just wrap another div around it, which has the border and the padding you want.

File relativeFile = new File(getClass().getResource("/icons/forIcon.png").toURI());
myJFrame.setIconImage(tk.getImage(relativeFile.getAbsolutePath()));

Wrap all those cases into one.

SELECT
    col1,
    col2,
    col3,
    CASE
        WHEN condition1 THEN calculation1 
        WHEN condition2 THEN calculation2
        WHEN condition3 THEN calculation3
        WHEN condition4 THEN calculation4
        WHEN condition5 THEN calculation5
        ELSE NULL         
    END AS 'calculatedcol1',
    col4,
    col5 -- etc

Here's what I suggest and what has worked for me. In your application class, implement an Application.ActivityLifeCycleCallbacks listener and set a variable in your application class. Then query the variable as needed.

class YourApplication: Application.ActivityLifeCycleCallbacks {
    
    var currentActivity: Activity? = null

    fun onCreate() {
        registerActivityLifecycleCallbacks(this)
    }

    ...
    
    override fun onActivityResumed(activity: Activity) {
        currentActivity = activity
    }
}

What helped me were the suggestions by @carlspring (create a settings.xml to configure your http proxy):

<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" 
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                              http://maven.apache.org/xsd/settings-1.0.0.xsd">

 <proxies>
    <proxy>
      <id>myproxy</id>
      <active>true</active>
      <protocol>http</protocol>

      <password>pass</password>  <!-- Put your password here -->
      <host>123.45.6.78</host>   <!-- Put the IP address of your proxy server here -->
      <port>80</port>            <!-- Put your proxy server's port number here -->
      <nonProxyHosts>local.net|some.host.com</nonProxyHosts> <!-- Do not use this setting unless you know what you're doing. -->
    </proxy>    
  </proxies> 
</settings>

AND then refreshing eclipse project maven as suggested by @Peter T :

"Force update of Snapshots/Releases" in Eclipse. this clears all errors. So right click on project -> Maven -> update project, then check the above option -> Ok. Hope this helps you.

There are a lot of good answers here. I had the same need after reloading my Django database.

But I needed:

• All in one Function
• Could fix one or more schemas at a time
• Could fix all or just one table at a time
• Also wanted a nice way to see exactly what had changed, or not changed

This seems very similar need to what the original ask was for.
Thanks to Baldiry and Mauro got me on the right track.

drop function IF EXISTS reset_sequences(text[], text) RESTRICT;
CREATE OR REPLACE FUNCTION reset_sequences(
    in_schema_name_list text[] = '{"django", "dbaas", "metrics", "monitor", "runner", "db_counts"}',
    in_table_name text = '%') RETURNS text[] as
$body$
  DECLARE changed_seqs text[];
  DECLARE sequence_defs RECORD; c integer ;
  BEGIN
    FOR sequence_defs IN
        select
          DISTINCT(ccu.table_name) as table_name,
          ccu.column_name as column_name,
          replace(replace(c.column_default,'''::regclass)',''),'nextval(''','') as sequence_name
          from information_schema.constraint_column_usage ccu,
               information_schema.columns c
          where ccu.table_schema = ANY(in_schema_name_list)
            and ccu.table_schema = c.table_schema
            AND c.table_name = ccu.table_name
            and c.table_name like in_table_name
            AND ccu.column_name = c.column_name
            AND c.column_default is not null
          ORDER BY sequence_name
   LOOP
      EXECUTE 'select max(' || sequence_defs.column_name || ') from ' || sequence_defs.table_name INTO c;
      IF c is null THEN c = 1; else c = c + 1; END IF;
      EXECUTE 'alter sequence ' || sequence_defs.sequence_name || ' restart  with ' || c;
      changed_seqs = array_append(changed_seqs, 'alter sequence ' || sequence_defs.sequence_name || ' restart with ' || c);
   END LOOP;
   changed_seqs = array_append(changed_seqs, 'Done');

   RETURN changed_seqs;
END
$body$ LANGUAGE plpgsql;

Then to Execute and See the changes run:

select *
from unnest(reset_sequences('{"django", "dbaas", "metrics", "monitor", "runner", "db_counts"}'));

Returns

activity_id_seq                          restart at 22
api_connection_info_id_seq               restart at 4
api_user_id_seq                          restart at 1
application_contact_id_seq               restart at 20

I know this question has already been answered but I want you to know that I found a drawable on Android Studio that is very similar to the pics you have in the question: Take a look at this:

android:background="@drawable/abc_menu_dropdown_panel_holo_light"

It looks like this:

Hope it will be helpful

Edit

The option above is for the older versions of Android Studio so you may not find it. For newer versions:

android:background="@android:drawable/dialog_holo_light_frame"

Moreover, if you want to have your own custom shape, I suggest to use a drawing software like Photoshop and draw it.

Don't forget to save it as .9.png file (example: my_background.9.png)

Read the documentation: Draw 9-patch

Edit 2

An even better and less hard working solution is to use a CardView and set app:cardPreventCornerOverlap="false" to prevent views to overlap the borders:

<android.support.v7.widget.CardView
    android:id="@+id/card_view"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:cardCornerRadius="2dp"
    app:cardElevation="2dp"
    app:cardPreventCornerOverlap="false"
    app:contentPadding="0dp">

    <!-- your layout stuff here -->

</android.support.v7.widget.CardView>

Also make sure to have included the latest version in the build.gradle, current is

compile 'com.android.support:cardview-v7:26.0.0'

var checkboxes = document.getElementsByName('location[]');
var vals = "";
for (var i=0, n=checkboxes.length;i<n;i++) 
{
    if (checkboxes[i].checked) 
    {
        vals += ","+checkboxes[i].value;
    }
}
if (vals) vals = vals.substring(1);

So, here is an example of the dateutil.relativedelta which I found useful for iterating through the past year, skipping a month each time to the present date:

>>> import datetime
>>> from dateutil.relativedelta import relativedelta
>>> today = datetime.datetime.today()
>>> month_count = 0
>>> while month_count < 12:
...  day = today - relativedelta(months=month_count)
...  print day
...  month_count += 1
... 
2010-07-07 10:51:45.187968
2010-06-07 10:51:45.187968
2010-05-07 10:51:45.187968
2010-04-07 10:51:45.187968
2010-03-07 10:51:45.187968
2010-02-07 10:51:45.187968
2010-01-07 10:51:45.187968
2009-12-07 10:51:45.187968
2009-11-07 10:51:45.187968
2009-10-07 10:51:45.187968
2009-09-07 10:51:45.187968
2009-08-07 10:51:45.187968

As with the other answers, you have to figure out what you actually mean by "6 months from now." If you mean "today's day of the month in the month six years in the future" then this would do:

datetime.datetime.now() + relativedelta(months=6)

in kotlin do it as below by using html

HtmlCompat.fromHtml("<html><body><h1>This is Large Heading :-</h1><br>This is normal size<body></html>",HtmlCompat.FROM_HTML_MODE_LEGACY)

you are confusing the concept of appending and prepending. the following code is prepending:

sys.path.insert(1,'/thePathToYourFolder/')

it places the new information at the beginning (well, second, to be precise) of the search sequence that your interpreter will go through. sys.path.append() puts things at the very end of the search sequence.

it is advisable that you use something like virtualenv instead of manually coding your package directories into the PYTHONPATH everytime. for setting up various ecosystems that separate your site-packages and possible versions of python, read these two blogs:

1. python ecosystems introduction

2. bootstrapping python virtual environments

if you do decide to move down the path to environment isolation you would certainly benefit by looking into virtualenvwrapper: http://www.doughellmann.com/docs/virtualenvwrapper/

Use single class name something like class="active" and add it only to current page instead of all pages. If you are at Home something like below:

<ul id="navigation">
<li class="active"><a href="/">Home</a></li>
<li class=""><a href="theatre.php">Theatre</a></li>
<li class=""><a href="programming.php">Programming</a></li> 
</ul>

and your CSS like

li.active{
color: #640200;
}

Also if you know how to make user become the super-user that would be nice also. Thanks!

sudo. su. chmod 04500. (setuid() & seteuid(), but they require you to already be root. E..g. chmod'ed 04***.)

Take care. These can open "interesting" security holes...

Depending on what you are doing, you may not need root. (For instance: I'll often chmod/chown /dev devices (serial ports, etc) (under sudo root) so I can use them from my software without being root. On the other hand, that doesn't work so well when loading/unloading kernel modules...)

Check the HTTP headers that chrome is sending with the request (Using browser extension or proxy) then try sending the same headers with CURL - Possibly one at a time till you figure out which header(s) makes the request work.

curl -A [user-agent] -H [headers] "http://something.com/api"

The quickest solution is: set environment variable RANDFILE to path where the 'random state' file can be written (of course check the file access permissions), eg. in your command prompt:

set RANDFILE=C:\MyDir\.rnd
openssl genrsa -out my-prvkey.pem 1024

More explanations: OpenSSL on Windows tries to save the 'random state' file in the following order:

1. Path taken from RANDFILE environment variable
2. If HOME environment variable is set then : ${HOME}\.rnd
3. C:\.rnd

I'm pretty sure that in your case it ends up trying to save it in C:\.rnd (and it fails because lack of sufficient access rights). Unfortunately OpenSSL does not print the path that is actually tries to use in any error messages.

First of all it is unclear what type name has. If it has the type std::string then instead of

string nametext;
nametext = "Your name is" << name;

you should write

std::string nametext = "Your name is " + name;

where operator + serves to concatenate strings.

If name is a character array then you may not use operator + for two character arrays (the string literal is also a character array), because character arrays in expressions are implicitly converted to pointers by the compiler. In this case you could write

std::string nametext( "Your name is " );
nametext.append( name );

or

std::string nametext( "Your name is " );
nametext += name;

$(window).height();   // returns height of browser viewport
$(document).height(); // returns height of HTML document

As documented here: http://api.jquery.com/height/

On mobile iOS the click event does not bubble to the document body and thus cannot be used with .live() events. If you have to use a non native click-able element like a div or section is to use cursor: pointer; in your css for the non-hover on the element in question. If that is ugly you could look into delegate().

To set value

 $('#searchField').val('your_value');

to retrieve value

$('#searchField').val();

@last_run_time is a 9.4. User-Defined Variables and last_run_time datetime one 13.6.4.1. Local Variable DECLARE Syntax, are different variables.

Try: SELECT last_run_time;

UPDATE

Example:

/* CODE FOR DEMONSTRATION PURPOSES */
DELIMITER $$

CREATE PROCEDURE `sp_test`()
BEGIN
    DECLARE current_procedure_name CHAR(60) DEFAULT 'accounts_general';
    DECLARE last_run_time DATETIME DEFAULT NULL;
    DECLARE current_run_time DATETIME DEFAULT NOW();

    -- Define the last run time
    SET last_run_time := (SELECT MAX(runtime) FROM dynamo.runtimes WHERE procedure_name = current_procedure_name);

    -- if there is no last run time found then use yesterday as starting point
    IF(last_run_time IS NULL) THEN
        SET last_run_time := DATE_SUB(NOW(), INTERVAL 1 DAY);
    END IF;

    SELECT last_run_time;

    -- Insert variables in table2
    INSERT INTO table2 (col0, col1, col2) VALUES (current_procedure_name, last_run_time, current_run_time);
END$$

There are two ways you could do this. Either create your own custom exception class to represent a divide by zero error or throw the same type of exception the java runtime would throw in this situation.

Define custom exception

public class DivideByZeroException() extends ArithmeticException {
}

Then in your code you would check for a divide by zero and throw this exception:

if (divisor == 0) throw new DivideByZeroException();

Throw ArithmeticException

Add to your code the check for a divide by zero and throw an arithmetic exception:

if (divisor == 0) throw new java.lang.ArithmeticException("/ by zero");

Additionally, you could consider throwing an illegal argument exception since a divisor of zero is an incorrect argument to pass to your setKp() method:

if (divisor == 0) throw new java.lang.IllegalArgumentException("divisor == 0");

Stacks for threads are often smaller. You can change the default at link time, or change at run time also. For reference, some defaults are:

• glibc i386, x86_64: 7.4 MB
• Tru64 5.1: 5.2 MB
• Cygwin: 1.8 MB
• Solaris 7..10: 1 MB
• MacOS X 10.5: 460 KB
• AIX 5: 98 KB
• OpenBSD 4.0: 64 KB
• HP-UX 11: 16 KB

check this if it works it works fine for me

<script>
  var windowObjectReference;
  var strWindowFeatures = "menubar=no,location=no,resizable=no,scrollbars=no,status=yes,width=400,height=350";

     function openRequestedPopup() {
      windowObjectReference = window.open("http://www.flyingedge.in/", "CNN_WindowName", strWindowFeatures);
     }
</script>

11-25 14:47:01.681: ERROR/AndroidRuntime(302): blah blah...requires android.permission.CALL_PHONE

^ The answer lies in the exception output "requires android.permission.CALL_PHONE" :)

OK guys, this is a small solution, but it works fine.

suppose the following code:

<div id='the_div_holder' style='height: 400px; overflow-y: scroll'>
  <div class='post'>1st post</div>
  <div class='post'>2nd post</div>
  <div class='post'>3rd post</div>
</div>

you want when a new post is added to 'the_div_holder' then it scrolls its inner content (the div's .post) to the last one like a chat. So, do the following whenever a new .post is added to the main div holder:

var scroll = function(div) {
    var totalHeight = 0;
    div.find('.post').each(function(){
       totalHeight += $(this).outerHeight();
    });
    div.scrollTop(totalHeight);
  }
  // call it:
  scroll($('#the_div_holder'));

Not very efficient, but if you must use a list, you can deference the iterator

*myList.begin()+N

By using order separately each subset gets order, but not the whole set, which is what you would want uniting two tables.

You should use something like this to have one ordered set:

SELECT TOP (100) PERCENT field1, field2, field3, field4, field5 FROM 
(SELECT table1.field1, table1.field2, table1.field3, table1.field4, table1.field5 FROM table1
UNION ALL 
SELECT table2.field1, table2.field2, table2.field3, table2.field4, table2.field5 FROM  table2) 
AS unitedTables ORDER BY field5 DESC

Whenever you encounter an error with this message use my_string.encode().

^{(where my_string is the string you're passing to a function/method).}

The encode method of str objects returns the encoded version of the string as a bytes object which you can then use. In this specific instance, socket methods such as .send expect a bytes object as the data to be sent, not a string object.

Since you have an object of type str and you're passing it to a function/method that expects an object of type bytes, an error is raised that clearly explains that:

TypeError: a bytes-like object is required, not 'str'

So the encode method of strings is needed, applied on a str value and returning a bytes value:

>>> s = "Hello world"
>>> print(type(s))
<class 'str'>
>>> byte_s = s.encode()
>>> print(type(byte_s))
<class 'bytes'>
>>> print(byte_s)
b"Hello world"

Here the prefix b in b'Hello world' denotes that this is indeed a bytes object. You can then pass it to whatever function is expecting it in order for it to run smoothly.

Change

Range(DataImportColumn & DataImportRow).Offset(0, 2).Value

to

Cells(DataImportRow,DataImportColumn).Value

When you just have the row and the column then you can use the cells() object. The syntax is Cells(Row,Column)

Also one more tip. You might want to fully qualify your Cells object. for example

ThisWorkbook.Sheets("WhatEver").Cells(DataImportRow,DataImportColumn).Value

If you use jQuery built-in after() with empty value it will create a dynamic object that will match your :after CSS selector.

$('.active').after().click(function () {
    alert('clickable!');
});

See the jQuery documentation.

A primary key is a column (or columns) in a table that uniquely identifies the rows in that table.

CUSTOMERS


CustomerNo  FirstName   LastName
1   Sally   Thompson
2   Sally   Henderson
3   Harry   Henderson
4   Sandra  Wellington

For example, in the table above, CustomerNo is the primary key.

The values placed in primary key columns must be unique for each row: no duplicates can be tolerated. In addition, nulls are not allowed in primary key columns.

So, having told you that it is possible to use one or more columns as a primary key, how do you decide which columns (and how many) to choose?

Well there are times when it is advisable or essential to use multiple columns. However, if you cannot see an immediate reason to use multiple columns, then use one. This isn't an absolute rule, it is simply advice. However, primary keys made up of single columns are generally easier to maintain and faster in operation. This means that if you query the database, you will usually get the answer back faster if the tables have single column primary keys.

Next question — which column should you pick? The easiest way to choose a column as a primary key (and a method that is reasonably commonly employed) is to get the database itself to automatically allocate a unique number to each row.

In a table of employees, clearly any column like FirstName is a poor choice since you cannot control employee's first names. Often there is only one choice for the primary key, as in the case above. However, if there is more than one, these can be described as 'candidate keys' — the name reflects that they are candidates for the responsible job of primary key.

find "${search_dir}" "${work_dir}" -mindepth 1 -maxdepth 1 -type f -print0 | xargs -0 -I {} echo "{}"

And BTW, in C++ this is a compiler extension, the standard does not define long long, thats part of C99.

You application of js and php in totally invalid.

You have to understand a fact that JS runs on clientside, once the page loads it does not care, whether the page was a php page or jsp or asp. It executes of DOM and is related to it only.

However you can do something like this

var newLocation = "<?php echo $newlocation; ?>";
window.location = newLocation;

You see, by the time the script is loaded, the above code renders into different form, something like this

var newLocation = "your/redirecting/page.php";
window.location = newLocation;

Like above, there are many possibilities of php and js fusions and one you are doing is not one of them.

Here is a very simple piece of C# code to test the CommandTimeout with. It creates a new command which will wait for 2 seconds. Set the CommandTimeout to 1 second and you will see an exception when running it. Setting the CommandTimeout to either 0 or something higher than 2 will run fine. By the way, the default CommandTimeout is 30 seconds.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

      builder.IntegratedSecurity = true;
      builder.InitialCatalog = "master";

      var connectionString = builder.ConnectionString;

      using (var connection = new SqlConnection(connectionString))
      {
        connection.Open();

        using (var command = connection.CreateCommand())
        {
          command.CommandText = "WAITFOR DELAY '00:00:02'";
          command.CommandTimeout = 1;

          command.ExecuteNonQuery();
        }
      }
    }
  }
}

In the Plist add the following properties.

-> Status bar is initially hidden = YES

-> View controller-based status bar appearance = NO

Add both - now the status bar will disappear.

The two socket options SO_RCVTIMEO and SO_SNDTIMEO have no effect on connect. Below is a link to the screenshot which includes this explanation, here I am just briefing it. The apt way of implementing timeouts with connect are using signal or select or poll.

Signals

connect can be interrupted by a self generated signal SIGALRM by using syscall (wrapper) alarm. But, a signal disposition should be installed for the same signal otherwise the program would be terminated. The code goes like this...

#include<stdio.h>
#include<stdlib.h>
#include<unistd.h>
#include<sys/socket.h>
#include<netinet/in.h>
#include<signal.h>
#include<errno.h>

static void signal_handler(int signo)
{
    return; // Do nothing just interrupt.
}

int main()
{
    /* Register signal handler */

    struct sigaction act, oact;

    act.sa_handler = signal_handler;
    sigemptyset(&act.sa_mask);
    act.sa_flags = 0;

#ifdef SA_INTERRUPT
    act.sa_flags |= SA_INTERRUPT;
#endif

    if(sigaction(SIGALRM, &act, &oact) < 0)  // Error registering signal handler.
    {
        fprintf(stderr, "Error registering signal disposition\n");
        exit(1);
    }

    /* Prepare your socket and sockaddr structures */

    int sockfd;
    struct sockaddr* servaddr;

    /* Implementing timeout connect */

    int sec = 30;

    if(alarm(sec) != 0)
        fprintf(stderr, "Already timer was set\n");

    if(connect(sockfd, servaddr, sizeof(struct sockaddr)) < 0)
    {
        if(errno == EINTR)
            fprintf(stderr, "Connect timeout\n");
        else
            fprintf(stderr, "Connect failed\n");

        close(sockfd);

        exit(1);
    }

    alarm(0);  /* turn off the alarm */

    sigaction(SIGALRM, &oact, NULL);  /* Restore the default actions of SIGALRM */

    /* Use socket */


    /* End program */

    close(sockfd);
    return 0;
}

Select or Poll

As already some users provided nice explanation on how to use select to achieve connect timeout, it would not be necessary for me to reiterate the same. poll can be used in the same way. However, there are few mistakes that are common in all of the answers, which I would like to address.

• Even though socket is non-blocking, if the server to which we are connecting is on the same local machine, connect may return with success. So it is advised to check the return value of connect before calling select.

• Berkeley-derived implementations (and POSIX) have the following rules for non-blocking sockets and connect.

  1) When the connection completes successfully, the descriptor becomes writable (p. 531 of TCPv2).

  2) When the connection establishment encounters an error, the descriptor becomes both readable and writable (p. 530 of TCPv2).

So the code should handle these cases, here I just code the necessary modifications.

/* All the code stays */

/* Modifications at connect */

int conn_ret = connect(sockfd, servaddr, sizeof(struct sockdaddr));

if(conn_ret == 0)
    goto done;

/* Modifications at select */

int sec = 30;
for( ; ; )
{
    struct timeval timeo;
    timeo.tv_sec = sec;
    timeo.tv_usec = 0;

    fd_set wr_set, rd_set;
    FDZERO(&wr_set);
    FD_SET(sockfd, &wr_set);
    rd_set = wr_set;
    int sl_ret = select(sockfd + 1, &rd_set, &wr_set, NULL, &timeo);

    /* All the code stays */
}


done:

    /* Use your socket */

It works by using recursive CTE as the list of positions, from 1 to 100 by default. If you need to work with string longer than 100, simply call this function using 'option (maxrecursion 4000)' like the following:

select * from FnSplitToTableInt
(
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0, ' + 
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0, ' +
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0, ' +
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0, ' +
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0'
) 
option (maxrecursion 4000)

Do you want to find elements that contain "match", or that equal "match"?

This will find elements that have text nodes that equal 'match' (matches none of the elements because of leading and trailing whitespace in random2):

//*[text()='match']

This will find all elements that have text nodes that equal "match", after removing leading and trailing whitespace(matches random2):

//*[normalize-space(text())='match']

This will find all elements that contain 'match' in the text node value (matches random2 and random3):

//*[contains(text(),'match')]

This XPATH 2.0 solution uses the matches() function and a regex pattern that looks for text nodes that contain 'match' and begin at the start of the string(i.e. ^) or a word boundary (i.e. \W) and terminated by the end of the string (i.e. $) or a word boundary. The third parameter i evaluates the regex pattern case-insensitive. (matches random2)

//*[matches(text(),'(^|\W)match($|\W)','i')]

I had the same error. What worked for me is when you go for the SMSS GUI option, look at General, Files in Options settings. After I did that (replace DB, set location) all went well.

I think the only foolproof method you can have is creating a Contact Me page that is a form that submits to a script that sends to your email address. That way, your address is never exposed to the public at all. This may be undesirable for some reason, but I think it's a pretty good solution. It often irks me when I'm forced to copy/paste someone's email address from their site to my mail client and send them a message; I'd rather do it right through a form on their site. Also, this approach allows you to have anonymous comments sent to you, etc. Just be sure to protect your form using some kind of anti-bot scheme, such as a captcha. There are plenty of them discussed here on SO.

They're essentially the same... They both use swig for templating, they both use karma and mocha for tests, passport integration, nodemon, etc.

Why so similar? Mean.js is a fork of Mean.io and both initiatives were started by the same guy... Mean.io is now under the umbrella of the company Linnovate and looks like the guy (Amos Haviv) stopped his collaboration with this company and started Mean.js. You can read more about the reasons here.

Now... main (or little) differences you can see right now are:

SCAFFOLDING AND BOILERPLATE GENERATION

Mean.io uses a custom cli tool named 'mean'
Mean.js uses Yeoman Generators

MODULARITY

Mean.io uses a more self-contained node packages modularity with client and server files inside the modules.
Mean.js uses modules just in the front-end (for angular), and connects them with Express. Although they were working on vertical modules as well...

BUILD SYSTEM

Mean.io has recently moved to gulp
Mean.js uses grunt

DEPLOYMENT

Both have Dockerfiles in their respective repos, and Mean.io has one-click install on Google Compute Engine, while Mean.js can also be deployed with one-click install on Digital Ocean.

DOCUMENTATION

Mean.io has ok docs
Mean.js has AWESOME docs

COMMUNITY

Mean.io has a bigger community since it was the original boilerplate
Mean.js has less momentum but steady growth

On a personal level, I like more the philosophy and openness of MeanJS and more the traction and modules/packages approach of MeanIO. Both are nice, and you'll end probably modifying them, so you can't really go wrong picking one or the other. Just take them as starting point and as a learning exercise.

ALTERNATIVE “MEAN” SOLUTIONS

MEAN is a generic way (coined by Valeri Karpov) to describe a boilerplate/framework that takes "Mongo + Express + Angular + Node" as the base of the stack. You can find frameworks with this stack that use other denomination, some of them really good for RAD (Rapid Application Development) and building SPAs. Eg:

• Meteor. Now with official Angular support, represents a great MEAN stack
• StrongLoop Loopback (main Node.js core contributors and Express maintainers)
• Generator Angular Fullstack
• Sails.js
• Cleverstack
• Deployd, etc (there are more)

You also have Hackathon Starter. It doesn't have A of MEAN (it is 'MEN'), but it rocks..

Have fun!

This will change only height of the element, to reduce the width you have to use grid system classes like col-xs-* col-md-* col-lg-*.

Example col-md-3. See doc here http://getbootstrap.com/css/#grid

I have some code in my game that displays live score. It is in a function for quick access.

   scoretext=font.render("Score:"+str(score), 1,(255,255,255))
   screen.blit(scoretext, (500, 457))

and I call it using this in my while loop:

If you enabled it as a DHCP client then your router should get an IP address from a DHCP server. If you connect your router on a net with a DHCP server you should reach your router's administrator page on the IP address assigned by the DHCP.

Now .find and .find_by_id methods are deprecated in rails 4. So instead we can use below:

Comment.where(id: [2, 3, 5])

It will work even if some of the ids don't exist. This works in the

user.comments.where(id: avoided_ids_array)

Also for excluding ID's

Comment.where.not(id: [2, 3, 5])

Using Console to read input (usable only outside of an IDE):

System.out.print("Enter something:");
String input = System.console().readLine();

Another way (works everywhere):

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class Test {
    public static void main(String[] args) throws IOException { 
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        System.out.print("Enter String");
        String s = br.readLine();
        System.out.print("Enter Integer:");
        try {
            int i = Integer.parseInt(br.readLine());
        } catch(NumberFormatException nfe) {
            System.err.println("Invalid Format!");
        }
    }
}

System.console() returns null in an IDE.
So if you really need to use System.console(), read this solution from McDowell.

F5 is a standard page reload.

Ctrl + F5 refreshes the page by clearing the cached content of the page.

Having the cursor in the address field and pressing Enter will also do the same as Ctrl + F5.

Those blank lines between your ?> and <?php tags are being sent to the client.

When the first one of those is sent, it causes your headers to be sent first.

Once that happens, you can't modify the headers any more.

Remove those unnecessary tags, have it all in one big <?php block.

I think the best way is to store them in some yml file and then load that file using this command in intializer file

APP_CONFIG = YAML.load_file("#{Rails.root}/config/CONFIG.yml")[Rails.env].to_hash

you can easily access environment related config variables.

Your Yml file key value structure:

development:
  app_key: 'abc'
  app_secret: 'abc'

production:
  app_key: 'xyz'
  app_secret: 'ghq'

Set the GET query parameters as managed properties in faces-config.xml so that you don't need to gather them manually:

<managed-bean>
    <managed-bean-name>forward</managed-bean-name>
    <managed-bean-class>com.example.ForwardBean</managed-bean-class>
    <managed-bean-scope>request</managed-bean-scope>
    <managed-property>
        <property-name>action</property-name>
        <value>#{param.action}</value>
    </managed-property>
    <managed-property>
        <property-name>actionParam</property-name>
        <value>#{param.actionParam}</value>
    </managed-property>
</managed-bean>

This way the request forward.jsf?action=outcome1&actionParam=123 will let JSF set the action and actionParam parameters as action and actionParam properties of the ForwardBean.

Create a small view forward.xhtml (so small that it fits in default response buffer (often 2KB) so that it can be resetted by the navigationhandler, otherwise you've to increase the response buffer in the servletcontainer's configuration), which invokes a bean method on beforePhase of the f:view:

<!DOCTYPE html>
<html xmlns:f="http://java.sun.com/jsf/core">
    <f:view beforePhase="#{forward.navigate}" />
</html>

The ForwardBean can look like this:

public class ForwardBean {
    private String action;
    private String actionParam;

    public void navigate(PhaseEvent event) {
        FacesContext facesContext = FacesContext.getCurrentInstance();
        String outcome = action; // Do your thing?
        facesContext.getApplication().getNavigationHandler().handleNavigation(facesContext, null, outcome);
    }

    // Add/generate the usual boilerplate.
}

The navigation-rule speaks for itself (note the <redirect /> entries which would do ExternalContext#redirect() instead of ExternalContext#dispatch() under the covers):

<navigation-rule>
    <navigation-case>
        <from-outcome>outcome1</from-outcome>
        <to-view-id>/outcome1.xhtml</to-view-id>
        <redirect />
    </navigation-case>
    <navigation-case>
        <from-outcome>outcome2</from-outcome>
        <to-view-id>/outcome2.xhtml</to-view-id>
        <redirect />
    </navigation-case>
</navigation-rule>

An alternative is to use forward.xhtml as

<!DOCTYPE html>
<html>#{forward}</html>

and update the navigate() method to be invoked on @PostConstruct (which will be invoked after bean's construction and all managed property setting):

@PostConstruct
public void navigate() {
    // ...
}    

It has the same effect, however the view side is not really self-documenting. All it basically does is printing ForwardBean#toString() (and hereby implicitly constructing the bean if not present yet).

Note for the JSF2 users, there is a cleaner way of passing parameters with <f:viewParam> and more robust way of handling the redirect/navigation by <f:event type="preRenderView">. See also among others:

• Hit a bean method and redirect on a GET request
• Is there any easy way to preprocess and redirect GET requests?

defaultMember already is an alias - it doesn't need to be the name of the exported function/thing. Just do

import alias from 'my-module';

Alternatively you can do

import {default as alias} from 'my-module';

but that's rather esoteric.

There is usually no difference, as far as page rendering goes. It's a huge facility developer-side, though, when your web project grows bigger.

I make use of both in this fashion:

• .PHP Page doesn't contain view-related code
• .PHTML Page contains little (if any) data logic and the most part of it is presentation-related

In support of the answer that @tetra gave, I want to point out that if the image is an SVG, then resizing the actual image is not necessary.

Since an SVG file is just XML you can specify whatever size you want it to appear within the XML.

However, if you are using the same SVG image in different places and need it to be different sizes, then using background-size is very helpful. SVG files are inherently smaller than raster images anyway and resizing on the fly with CSS can be very helpful without any performance cost that I am aware of, and certainly little to no loss of quality.

Here is a quick example:

<div class="hasBackgroundImage">content</div>

.hasBackgroundImage
{
    background: transparent url('/image/background.svg') no-repeat 10px 5px;
    background-size: 1.4em;
}

(Note: this works for me in OS X 10.7 with Firefox 8, Safari 5.1, and Chrome 16.0.912.63)

I had to do 2 steps:

Everyone explained pretty well on it. Let me answer when should this class be used.

When Should You Use NoSuchElementException?

Java includes a few different ways to iterate through elements in a collection. The first of these classes, Enumeration, was introduced in JDK1.0 and is generally considered deprecated in favor of newer iteration classes, like Iterator and ListIterator.

As with most programming languages, the Iterator class includes a hasNext() method that returns a boolean indicating if the iteration has anymore elements. If hasNext() returns true, then the next() method will return the next element in the iteration. Unlike Enumeration, Iterator also has a remove() method, which removes the last element that was obtained via next().

While Iterator is generalized for use with all collections in the Java Collections Framework, ListIterator is more specialized and only works with List-based collections, like ArrayList, LinkedList, and so forth. However, ListIterator adds even more functionality by allowing iteration to traverse in both directions via hasPrevious() and previous() methods.

?:

1. Set your PERL_UNICODE envariable to AS. This makes all Perl scripts decode @ARGV as UTF-8 strings, and sets the encoding of all three of stdin, stdout, and stderr to UTF-8. Both these are global effects, not lexical ones.

2. At the top of your source file (program, module, library, dohickey), prominently assert that you are running perl version 5.12 or better via:

   use v5.12;  # minimal for unicode string feature
   use v5.14;  # optimal for unicode string feature
   

3. Enable warnings, since the previous declaration only enables strictures and features, not warnings. I also suggest promoting Unicode warnings into exceptions, so use both these lines, not just one of them. Note however that under v5.14, the utf8 warning class comprises three other subwarnings which can all be separately enabled: nonchar, surrogate, and non_unicode. These you may wish to exert greater control over.

   use warnings;
   use warnings qw( FATAL utf8 );
   

4. Declare that this source unit is encoded as UTF-8. Although once upon a time this pragma did other things, it now serves this one singular purpose alone and no other:

   use utf8;
   

5. Declare that anything that opens a filehandle within this lexical scope but not elsewhere is to assume that that stream is encoded in UTF-8 unless you tell it otherwise. That way you do not affect other module’s or other program’s code.

   use open qw( :encoding(UTF-8) :std );
   

6. Enable named characters via \N{CHARNAME}.

   use charnames qw( :full :short );
   

7. If you have a DATA handle, you must explicitly set its encoding. If you want this to be UTF-8, then say:

   binmode(DATA, ":encoding(UTF-8)");
   

There is of course no end of other matters with which you may eventually find yourself concerned, but these will suffice to approximate the state goal to “make everything just work with UTF-8”, albeit for a somewhat weakened sense of those terms.

One other pragma, although it is not Unicode related, is:

      use autodie;

It is strongly recommended.

? ?

My own boilerplate these days tends to look like this:

use 5.014;

use utf8;
use strict;
use autodie;
use warnings; 
use warnings    qw< FATAL  utf8     >;
use open        qw< :std  :utf8     >;
use charnames   qw< :full >;
use feature     qw< unicode_strings >;

use File::Basename      qw< basename >;
use Carp                qw< carp croak confess cluck >;
use Encode              qw< encode decode >;
use Unicode::Normalize  qw< NFD NFC >;

END { close STDOUT }

if (grep /\P{ASCII}/ => @ARGV) { 
   @ARGV = map { decode("UTF-8", $_) } @ARGV;
}

$0 = basename($0);  # shorter messages
$| = 1;

binmode(DATA, ":utf8");

# give a full stack dump on any untrapped exceptions
local $SIG{__DIE__} = sub {
    confess "Uncaught exception: @_" unless $^S;
};

# now promote run-time warnings into stack-dumped
#   exceptions *unless* we're in an try block, in
#   which case just cluck the stack dump instead
local $SIG{__WARN__} = sub {
    if ($^S) { cluck   "Trapped warning: @_" } 
    else     { confess "Deadly warning: @_"  }
};

while (<>)  {
    chomp;
    $_ = NFD($_);
    ...
} continue {
    say NFC($_);
}

__END__

Saying that “Perl should [somehow!] enable Unicode by default” doesn’t even start to begin to think about getting around to saying enough to be even marginally useful in some sort of rare and isolated case. Unicode is much much more than just a larger character repertoire; it’s also how those characters all interact in many, many ways.

Even the simple-minded minimal measures that (some) people seem to think they want are guaranteed to miserably break millions of lines of code, code that has no chance to “upgrade” to your spiffy new Brave New World modernity.

It is way way way more complicated than people pretend. I’ve thought about this a huge, whole lot over the past few years. I would love to be shown that I am wrong. But I don’t think I am. Unicode is fundamentally more complex than the model that you would like to impose on it, and there is complexity here that you can never sweep under the carpet. If you try, you’ll break either your own code or somebody else’s. At some point, you simply have to break down and learn what Unicode is about. You cannot pretend it is something it is not.

goes out of its way to make Unicode easy, far more than anything else I’ve ever used. If you think this is bad, try something else for a while. Then come back to : either you will have returned to a better world, or else you will bring knowledge of the same with you so that we can make use of your new knowledge to make better at these things.

?

At a minimum, here are some things that would appear to be required for to “enable Unicode by default”, as you put it:

1. All source code should be in UTF-8 by default. You can get that with use utf8 or export PERL5OPTS=-Mutf8.

2. The DATA handle should be UTF-8. You will have to do this on a per-package basis, as in binmode(DATA, ":encoding(UTF-8)").

3. Program arguments to scripts should be understood to be UTF-8 by default. export PERL_UNICODE=A, or perl -CA, or export PERL5OPTS=-CA.

4. The standard input, output, and error streams should default to UTF-8. export PERL_UNICODE=S for all of them, or I, O, and/or E for just some of them. This is like perl -CS.

5. Any other handles opened by should be considered UTF-8 unless declared otherwise; export PERL_UNICODE=D or with i and o for particular ones of these; export PERL5OPTS=-CD would work. That makes -CSAD for all of them.

6. Cover both bases plus all the streams you open with export PERL5OPTS=-Mopen=:utf8,:std. See uniquote.

7. You don’t want to miss UTF-8 encoding errors. Try export PERL5OPTS=-Mwarnings=FATAL,utf8. And make sure your input streams are always binmoded to :encoding(UTF-8), not just to :utf8.

8. Code points between 128–255 should be understood by to be the corresponding Unicode code points, not just unpropertied binary values. use feature "unicode_strings" or export PERL5OPTS=-Mfeature=unicode_strings. That will make uc("\xDF") eq "SS" and "\xE9" =~ /\w/. A simple export PERL5OPTS=-Mv5.12 or better will also get that.

9. Named Unicode characters are not by default enabled, so add export PERL5OPTS=-Mcharnames=:full,:short,latin,greek or some such. See uninames and tcgrep.

10. You almost always need access to the functions from the standard Unicode::Normalize module various types of decompositions. export PERL5OPTS=-MUnicode::Normalize=NFD,NFKD,NFC,NFKD, and then always run incoming stuff through NFD and outbound stuff from NFC. There’s no I/O layer for these yet that I’m aware of, but see nfc, nfd, nfkd, and nfkc.

11. String comparisons in using eq, ne, lc, cmp, sort, &c&cc are always wrong. So instead of @a = sort @b, you need @a = Unicode::Collate->new->sort(@b). Might as well add that to your export PERL5OPTS=-MUnicode::Collate. You can cache the key for binary comparisons.

12. built-ins like printf and write do the wrong thing with Unicode data. You need to use the Unicode::GCString module for the former, and both that and also the Unicode::LineBreak module as well for the latter. See uwc and unifmt.

13. If you want them to count as integers, then you are going to have to run your \d+ captures through the Unicode::UCD::num function because ’s built-in atoi(3) isn’t currently clever enough.

14. You are going to have filesystem issues on filesystems. Some filesystems silently enforce a conversion to NFC; others silently enforce a conversion to NFD. And others do something else still. Some even ignore the matter altogether, which leads to even greater problems. So you have to do your own NFC/NFD handling to keep sane.

15. All your code involving a-z or A-Z and such MUST BE CHANGED, including m//, s///, and tr///. It’s should stand out as a screaming red flag that your code is broken. But it is not clear how it must change. Getting the right properties, and understanding their casefolds, is harder than you might think. I use unichars and uniprops every single day.

16. Code that uses \p{Lu} is almost as wrong as code that uses [A-Za-z]. You need to use \p{Upper} instead, and know the reason why. Yes, \p{Lowercase} and \p{Lower} are different from \p{Ll} and \p{Lowercase_Letter}.

17. Code that uses [a-zA-Z] is even worse. And it can’t use \pL or \p{Letter}; it needs to use \p{Alphabetic}. Not all alphabetics are letters, you know!

18. If you are looking for variables with /[\$\@\%]\w+/, then you have a problem. You need to look for /[\$\@\%]\p{IDS}\p{IDC}*/, and even that isn’t thinking about the punctuation variables or package variables.

19. If you are checking for whitespace, then you should choose between \h and \v, depending. And you should never use \s, since it DOES NOT MEAN [\h\v], contrary to popular belief.

20. If you are using \n for a line boundary, or even \r\n, then you are doing it wrong. You have to use \R, which is not the same!

21. If you don’t know when and whether to call Unicode::Stringprep, then you had better learn.

22. Case-insensitive comparisons need to check for whether two things are the same letters no matter their diacritics and such. The easiest way to do that is with the standard Unicode::Collate module. Unicode::Collate->new(level => 1)->cmp($a, $b). There are also eq methods and such, and you should probably learn about the match and substr methods, too. These are have distinct advantages over the built-ins.

23. Sometimes that’s still not enough, and you need the Unicode::Collate::Locale module instead, as in Unicode::Collate::Locale->new(locale => "de__phonebook", level => 1)->cmp($a, $b) instead. Consider that Unicode::Collate::->new(level => 1)->eq("d", "ð") is true, but Unicode::Collate::Locale->new(locale=>"is",level => 1)->eq("d", " ð") is false. Similarly, "ae" and "æ" are eq if you don’t use locales, or if you use the English one, but they are different in the Icelandic locale. Now what? It’s tough, I tell you. You can play with ucsort to test some of these things out.

24. Consider how to match the pattern CVCV (consonsant, vowel, consonant, vowel) in the string “niño”. Its NFD form — which you had darned well better have remembered to put it in — becomes “nin\x{303}o”. Now what are you going to do? Even pretending that a vowel is [aeiou] (which is wrong, by the way), you won’t be able to do something like (?=[aeiou])\X) either, because even in NFD a code point like ‘ø’ does not decompose! However, it will test equal to an ‘o’ using the UCA comparison I just showed you. You can’t rely on NFD, you have to rely on UCA.

And that’s not all. There are a million broken assumptions that people make about Unicode. Until they understand these things, their code will be broken.

1. Code that assumes it can open a text file without specifying the encoding is broken.

2. Code that assumes the default encoding is some sort of native platform encoding is broken.

3. Code that assumes that web pages in Japanese or Chinese take up less space in UTF-16 than in UTF-8 is wrong.

4. Code that assumes Perl uses UTF-8 internally is wrong.

5. Code that assumes that encoding errors will always raise an exception is wrong.

6. Code that assumes Perl code points are limited to 0x10_FFFF is wrong.

7. Code that assumes you can set $/ to something that will work with any valid line separator is wrong.

8. Code that assumes roundtrip equality on casefolding, like lc(uc($s)) eq $s or uc(lc($s)) eq $s, is completely broken and wrong. Consider that the uc("s") and uc("?") are both "S", but lc("S") cannot possibly return both of those.

9. Code that assumes every lowercase code point has a distinct uppercase one, or vice versa, is broken. For example, "ª" is a lowercase letter with no uppercase; whereas both "?" and "?" are letters, but they are not lowercase letters; however, they are both lowercase code points without corresponding uppercase versions. Got that? They are not \p{Lowercase_Letter}, despite being both \p{Letter} and \p{Lowercase}.

10. Code that assumes changing the case doesn’t change the length of the string is broken.

11. Code that assumes there are only two cases is broken. There’s also titlecase.

12. Code that assumes only letters have case is broken. Beyond just letters, it turns out that numbers, symbols, and even marks have case. In fact, changing the case can even make something change its main general category, like a \p{Mark} turning into a \p{Letter}. It can also make it switch from one script to another.

13. Code that assumes that case is never locale-dependent is broken.

14. Code that assumes Unicode gives a fig about POSIX locales is broken.

15. Code that assumes you can remove diacritics to get at base ASCII letters is evil, still, broken, brain-damaged, wrong, and justification for capital punishment.

16. Code that assumes that diacritics \p{Diacritic} and marks \p{Mark} are the same thing is broken.

17. Code that assumes \p{GC=Dash_Punctuation} covers as much as \p{Dash} is broken.

18. Code that assumes dash, hyphens, and minuses are the same thing as each other, or that there is only one of each, is broken and wrong.

19. Code that assumes every code point takes up no more than one print column is broken.

20. Code that assumes that all \p{Mark} characters take up zero print columns is broken.

21. Code that assumes that characters which look alike are alike is broken.

22. Code that assumes that characters which do not look alike are not alike is broken.

23. Code that assumes there is a limit to the number of code points in a row that just one \X can match is wrong.

24. Code that assumes \X can never start with a \p{Mark} character is wrong.

25. Code that assumes that \X can never hold two non-\p{Mark} characters is wrong.

26. Code that assumes that it cannot use "\x{FFFF}" is wrong.

27. Code that assumes a non-BMP code point that requires two UTF-16 (surrogate) code units will encode to two separate UTF-8 characters, one per code unit, is wrong. It doesn’t: it encodes to single code point.

28. Code that transcodes from UTF-16 or UTF-32 with leading BOMs into UTF-8 is broken if it puts a BOM at the start of the resulting UTF-8. This is so stupid the engineer should have their eyelids removed.

29. Code that assumes the CESU-8 is a valid UTF encoding is wrong. Likewise, code that thinks encoding U+0000 as "\xC0\x80" is UTF-8 is broken and wrong. These guys also deserve the eyelid treatment.

30. Code that assumes characters like > always points to the right and < always points to the left are wrong — because they in fact do not.

31. Code that assumes if you first output character X and then character Y, that those will show up as XY is wrong. Sometimes they don’t.

32. Code that assumes that ASCII is good enough for writing English properly is stupid, shortsighted, illiterate, broken, evil, and wrong. Off with their heads! If that seems too extreme, we can compromise: henceforth they may type only with their big toe from one foot. (The rest will be duct taped.)

33. Code that assumes that all \p{Math} code points are visible characters is wrong.

34. Code that assumes \w contains only letters, digits, and underscores is wrong.

35. Code that assumes that ^ and ~ are punctuation marks is wrong.

36. Code that assumes that ü has an umlaut is wrong.

37. Code that believes things like ? contain any letters in them is wrong.

38. Code that believes \p{InLatin} is the same as \p{Latin} is heinously broken.

39. Code that believe that \p{InLatin} is almost ever useful is almost certainly wrong.

40. Code that believes that given $FIRST_LETTER as the first letter in some alphabet and $LAST_LETTER as the last letter in that same alphabet, that [${FIRST_LETTER}-${LAST_LETTER}] has any meaning whatsoever is almost always complete broken and wrong and meaningless.

41. Code that believes someone’s name can only contain certain characters is stupid, offensive, and wrong.

42. Code that tries to reduce Unicode to ASCII is not merely wrong, its perpetrator should never be allowed to work in programming again. Period. I’m not even positive they should even be allowed to see again, since it obviously hasn’t done them much good so far.

43. Code that believes there’s some way to pretend textfile encodings don’t exist is broken and dangerous. Might as well poke the other eye out, too.

44. Code that converts unknown characters to ? is broken, stupid, braindead, and runs contrary to the standard recommendation, which says NOT TO DO THAT! RTFM for why not.

45. Code that believes it can reliably guess the encoding of an unmarked textfile is guilty of a fatal mélange of hubris and naïveté that only a lightning bolt from Zeus will fix.

46. Code that believes you can use printf widths to pad and justify Unicode data is broken and wrong.

47. Code that believes once you successfully create a file by a given name, that when you run ls or readdir on its enclosing directory, you’ll actually find that file with the name you created it under is buggy, broken, and wrong. Stop being surprised by this!

48. Code that believes UTF-16 is a fixed-width encoding is stupid, broken, and wrong. Revoke their programming licence.

49. Code that treats code points from one plane one whit differently than those from any other plane is ipso facto broken and wrong. Go back to school.

50. Code that believes that stuff like /s/i can only match "S" or "s" is broken and wrong. You’d be surprised.

51. Code that uses \PM\pM* to find grapheme clusters instead of using \X is broken and wrong.

52. People who want to go back to the ASCII world should be whole-heartedly encouraged to do so, and in honor of their glorious upgrade they should be provided gratis with a pre-electric manual typewriter for all their data-entry needs. Messages sent to them should be sent via an ??????s telegraph at 40 characters per line and hand-delivered by a courier. STOP.

I don’t know how much more “default Unicode in ” you can get than what I’ve written. Well, yes I do: you should be using Unicode::Collate and Unicode::LineBreak, too. And probably more.

As you see, there are far too many Unicode things that you really do have to worry about for there to ever exist any such thing as “default to Unicode”.

What you’re going to discover, just as we did back in 5.8, that it is simply impossible to impose all these things on code that hasn’t been designed right from the beginning to account for them. Your well-meaning selfishness just broke the entire world.

And even once you do, there are still critical issues that require a great deal of thought to get right. There is no switch you can flip. Nothing but brain, and I mean real brain, will suffice here. There’s a heck of a lot of stuff you have to learn. Modulo the retreat to the manual typewriter, you simply cannot hope to sneak by in ignorance. This is the 21?? century, and you cannot wish Unicode away by willful ignorance.

You have to learn it. Period. It will never be so easy that “everything just works,” because that will guarantee that a lot of things don’t work — which invalidates the assumption that there can ever be a way to “make it all work.”

You may be able to get a few reasonable defaults for a very few and very limited operations, but not without thinking about things a whole lot more than I think you have.

As just one example, canonical ordering is going to cause some real headaches. "\x{F5}" ‘õ’, "o\x{303}" ‘õ’, "o\x{303}\x{304}" ‘?’, and "o\x{304}\x{303}" ‘o~’ should all match ‘õ’, but how in the world are you going to do that? This is harder than it looks, but it’s something you need to account for.

If there’s one thing I know about Perl, it is what its Unicode bits do and do not do, and this thing I promise you: “ _?_?_?_?_?_ _?_s_ _?_?_ _U_?_?_?_?_?_?_ _?_?_?_?_?_ _?_?_?_?_?_?_ _ ”

You cannot just change some defaults and get smooth sailing. It’s true that I run with PERL_UNICODE set to "SA", but that’s all, and even that is mostly for command-line stuff. For real work, I go through all the many steps outlined above, and I do it very, ** very** carefully.

¡?dl?? ???? ?do? pu? ???p ???u ? ???? ???nl poo?

An intuitive explanation to this is by simply analysing a single loop:

1. visit a vertex -> O(1)
2. a for loop on all the incident edges -> O(e) where e is a number of edges incident on a given vertex v.

So the total time for a single loop is O(1)+O(e). Now sum it for each vertex as each vertex is visited once. This gives

For every V
=> 

    O(1)
    +

    O(e)

=> O(V) + O(E)

I just use contentsMargin to fix the aspect ratio.

#pragma once

#include <QLabel>

class AspectRatioLabel : public QLabel
{
public:
    explicit AspectRatioLabel(QWidget* parent = nullptr, Qt::WindowFlags f = Qt::WindowFlags());
    ~AspectRatioLabel();

    void setPixmap(const QPixmap& pm);

protected:
    void resizeEvent(QResizeEvent* event) override;

private:
    void updateMargins();

    int pixmapWidth = 0;
    int pixmapHeight = 0;
};

#include "AspectRatioLabel.h"

AspectRatioLabel::AspectRatioLabel(QWidget* parent, Qt::WindowFlags f) : QLabel(parent, f)
{
}

AspectRatioLabel::~AspectRatioLabel()
{
}

void AspectRatioLabel::setPixmap(const QPixmap& pm)
{
    pixmapWidth = pm.width();
    pixmapHeight = pm.height();

    updateMargins();
    QLabel::setPixmap(pm);
}

void AspectRatioLabel::resizeEvent(QResizeEvent* event)
{
    updateMargins();
    QLabel::resizeEvent(event);
}

void AspectRatioLabel::updateMargins()
{
    if (pixmapWidth <= 0 || pixmapHeight <= 0)
        return;

    int w = this->width();
    int h = this->height();

    if (w <= 0 || h <= 0)
        return;

    if (w * pixmapHeight > h * pixmapWidth)
    {
        int m = (w - (pixmapWidth * h / pixmapHeight)) / 2;
        setContentsMargins(m, 0, m, 0);
    }
    else
    {
        int m = (h - (pixmapHeight * w / pixmapWidth)) / 2;
        setContentsMargins(0, m, 0, m);
    }
}

Works perfectly for me so far. You're welcome.

Here is the simplest way of achieving Light and Dark Theme for Toolbar.You have to change the value of app:theme of the Toolbar tag

• For Black Toolbar Title and Black Up arrow, your toolbar should implement following theme:

app:theme="@style/ThemeOverlay.AppCompat.Light"

• For White Toolbar Title and White Up arrow, your toolbar should implement following theme:

app:theme="@style/ThemeOverlay.AppCompat"

UPDATE: In iPhone OS 3.0 and later UITableViewCell now has a backgroundColor property that makes this really easy (especially in combination with the [UIColor colorWithPatternImage:] initializer). But I'll leave the 2.0 version of the answer here for anyone that needs it…

It's harder than it really should be. Here's how I did this when I had to do it:

You need to set the UITableViewCell's backgroundView property to a custom UIView that draws the border and background itself in the appropriate colors. This view needs to be able to draw the borders in 4 different modes, rounded on the top for the first cell in a section, rounded on the bottom for the last cell in a section, no rounded corners for cells in the middle of a section, and rounded on all 4 corners for sections that contain one cell.

Unfortunately I couldn't figure out how to have this mode set automatically, so I had to set it in the UITableViewDataSource's -cellForRowAtIndexPath method.

It's a real PITA but I've confirmed with Apple engineers that this is currently the only way.

Update Here's the code for that custom bg view. There's a drawing bug that makes the rounded corners look a little funny, but we moved to a different design and scrapped the custom backgrounds before I had a chance to fix it. Still this will probably be very helpful for you:

You are binding the click event to anchors with an href attribute with value sign_new.

Either bind anchors with class sign_new or bind anchors with href value #sign_up. I would prefer the former.

For those new to Java and wondering why Jiri's answer doesn't work, make sure you do what he says and handle the exception or else it won't compile. Here's the bare minimum:

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

public class ReadFile {

    public static void main(String args[]) throws IOException {
        BufferedReader br = new BufferedReader(new FileReader("test.txt"));
        for (String line; (line = br.readLine()) != null;) {
            System.out.print(line);
        }
        br.close()
    }
}

A safer way to approach breaking a foreach or while loop in PHP is to nest an incrementing counter variable and if conditional inside of the original loop. This gives you tighter control than break; which can cause havoc elsewhere on a complicated page.

Example:

// Setup a counter
$ImageCounter = 0;

// Increment through repeater fields
while ( condition ):
  $ImageCounter++;

   // Only print the first while instance
   if ($ImageCounter == 1) {
    echo 'It worked just once';
   }

// Close while statement
endwhile;

With the addition of androidx in Studio 3.0+ the Toolbar compatibility is now in a new library, accessible like this

import androidx.appcompat.widget.Toolbar

Here's one way, if you have subfolders in your test folder e.g.

/test
/test/server-test
/test/other-test

Then in linux you can use the find command to list all *.js files recursively and pass it to mocha:

mocha $(find test -name '*.js')

You can use the workbook.get_worksheet_by_name() feature: https://xlsxwriter.readthedocs.io/workbook.html#get_worksheet_by_name

According to https://xlsxwriter.readthedocs.io/changes.html the feature has been added on May 13, 2016.

"Release 0.8.7 - May 13 2016

-Fix for issue when inserting read-only images on Windows. Issue #352.

-Added get_worksheet_by_name() method to allow the retrieval of a worksheet from a workbook via its name.

-Fixed issue where internal file creation and modification dates were in the local timezone instead of UTC."

    // TODO Auto-generated catch block
} catch (IOException e) {
    // TODO Auto-generated catch block
}

So, you can add your parameters as BasicNameValuePair.

An alternative is to use (Http)URLConnection. See also Using java.net.URLConnection to fire and handle HTTP requests. This is actually the preferred method in newer Android versions (Gingerbread+). See also this blog, this developer doc and Android's HttpURLConnection javadoc.

You can flip it horizontally with CSS...

a:visited {
    -moz-transform: scaleX(-1);
    -o-transform: scaleX(-1);
    -webkit-transform: scaleX(-1);
    transform: scaleX(-1);
    filter: FlipH;
    -ms-filter: "FlipH";
}

jsFiddle.

If you want to flip vertically instead...

a:visited {
    -moz-transform: scaleY(-1);
    -o-transform: scaleY(-1);
    -webkit-transform: scaleY(-1);
    transform: scaleY(-1);
    filter: FlipV;
    -ms-filter: "FlipV";
}

On a POSIX system, you probably should use getline if it's available.

You also can use Chuck Falconer's public domain ggets function which provides syntax closer to gets but without the problems. (Chuck Falconer's website is no longer available, although archive.org has a copy, and I've made my own page for ggets.)

Number.isNaN(parseInt('-1')); // => false
Number.isNaN(parseInt('1.1')); // => false
Number.isNaN(parseInt('-1.1')); // => false

Number.isNaN(parseFloat('0b1')); // => false
Number.isNaN(parseFloat('0o1')); // => false
Number.isNaN(parseFloat('0xa')); // => false

// Edge cases that are debatable
Number.isNaN(parseFloat('-0b1')); // => false
Number.isNaN(parseFloat('-0o1')); // => false

Number.isNaN(parseFloat('Infinity')); // => false 
Number.isNaN(parseFloat('INFINITY')); // => true  
Number.isNaN(parseFloat('-Infinity')); // => false 
Number.isNaN(parseFloat('-INFINITY')); // => true

Notes:

• Only string, empty, and uninitialized values are considered in keeping with addressing the original question. Additional edge cases exist if arrays and objects are the values being considered.
• Characters in binary, octal, hexadecimal, and exponential notation are not case-sensitive (ie: '0xFF', '0XFF', '0xfF' etc. will all yield the same result in the test cases shown above).
• Unlike with Infinity (case-sensitive) in some cases, constants from the Number and Math objects passed as test cases in string format to any of the methods above will be determined to not be numbers.
• See here for an explanation of how arguments are converted to a Number and why the edge cases for null and empty strings exist.

Since -f caused another problem, I developed another solution.

• Create a base image in the parent folder
• Added the required files.
• Used this image as a base image for the project which in a descendant folder.

The -f flag does not solved my problem because my onbuild image looks for a file in a folder and had to call like this:

-f foo/bar/Dockerfile foo/bar

instead of

-f foo/bar/Dockerfile .

Also note that this is only solution for some cases as -f flag

I had almost the same problem, but with the following variation:

1. I've imported a ready-to-use maven project into Eclipse IDE from PC1 (project was working there perfectly) to another PC2
2. when was trying to run the project on PC 2 got the same error "Could not find or load main class"
3. I've checked PATH variable (it had many values in my case) and added JAVA_HOME variable (in my case it was JAVA_HOME = C:\Program Files\Java\jdk1.7.0_03) After restarting Ecplise it still didn't work
4. I've tried to run simple HelloWorld.java on PC2 (in another project) - it worked
5. So I've added HelloWorld class to the imported recently project, executed it there and - huh - my main class in that project started to run normally also.

That's quite odd behavour, I cannot completely understand it. Hope It'll help somebody. too.

Single comment ctrl + / and also multiple line comment you can select multiple line and then ctrl + /. Then, to remove comment you can use ctrl + c for both single line and multiple line comment.

I realize that this is an old question, but I'll post the solution for my use case, in case others run into the same situation I did when implementing James Hill's answer (above).

I found this question while trying to solve the same issue. James' answer got me 90% there. However, for my use case, selecting the item from the dropdown also triggered an action on the page from dropdown's onchange event. James' code as written did not trigger this event (at least in Firefox, which I was testing in). As a result, I made the following minor change:

function setSelectedValue(object, value) {
    for (var i = 0; i < object.options.length; i++) {
        if (object.options[i].text === value) {
            object.options[i].selected = true;
            object.onchange();
            return;
        }
    }

    // Throw exception if option `value` not found.
    var tag = object.nodeName;
    var str = "Option '" + value + "' not found";

    if (object.id != '') {
        str = str + " in //" + object.nodeName.toLowerCase()
              + "[@id='" + object.id + "']."
    }

    else if (object.name != '') {
        str = str + " in //" + object.nodeName.toLowerCase()
              + "[@name='" + object.name + "']."
    }

    else {
        str += "."
    }

    throw str;
}

Note the object.onchange() call, which I added to the original solution. This calls the handler to make certain that the action on the page occurs.

Edit

Added code to throw an exception if option value is not found; this is needed for my use case.

.foo {
   position : relative;
}
.foo .wrapper {
    background-image : url('semi-trans.png');
    z-index : 10;
    position : absolute;
    top : 0;
    left : 0;
}

<div class="foo">
   <img src="example.png" />
   <div class="wrapper">&nbsp;</div>
</div>

In Angular / Ionic / VueJS -- I just came up with a simple method of:

stripNaN(txt: any) {
    return txt.toString().replace(/[^a-zA-Z0-9]/g, "");
}

Usage on the view:

<a [href]="'tel:'+stripNaN(single.meta['phone'])" [innerHTML]="stripNaN(single.meta['phone'])"></a>

While I agree that the accepted answer is usually the best solution and definitely easier to use, I noticed no one displayed the proper usage of the iterator. So here is a quick example:

Iterator<Object> it = arrayList.iterator();
while(it.hasNext())
{
    Object obj = it.next();
    //Do something with obj
}

In chrome, your best option might be the Snippets tab under Sources in the Developer Tools.

It will allow you to write and run code, for example, in a about:blank page.

You can't just change the delimiters from ---- BEGIN SSH2 PUBLIC KEY ---- to -----BEGIN RSA PUBLIC KEY----- and expect that it will be sufficient to convert from one format to another (which is what you've done in your example).

This article has a good explanation about both formats.

What you get in an RSA PUBLIC KEY is closer to the content of a PUBLIC KEY, but you need to offset the start of your ASN.1 structure to reflect the fact that PUBLIC KEY also has an indicator saying which type of key it is (see RFC 3447). You can see this using openssl asn1parse and -strparse 19, as described in this answer.

EDIT: Following your edit, your can get the details of your RSA PUBLIC KEY structure using grep -v -- ----- | tr -d '\n' | base64 -d | openssl asn1parse -inform DER:

    0:d=0  hl=4 l= 266 cons: SEQUENCE          
    4:d=1  hl=4 l= 257 prim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
  265:d=1  hl=2 l=   3 prim: INTEGER           :010001

To decode the SSH key format, you need to use the data format specification in RFC 4251 too, in conjunction with RFC 4253:

   The "ssh-rsa" key format has the following specific encoding:

      string    "ssh-rsa"
      mpint     e
      mpint     n

For example, at the beginning, you get 00 00 00 07 73 73 68 2d 72 73 61. The first four bytes (00 00 00 07) give you the length. The rest is the string itself: 73=s, 68=h, ... -> 73 73 68 2d 72 73 61=ssh-rsa, followed by the exponent of length 1 (00 00 00 01 25) and the modulus of length 256 (00 00 01 00 7f ...).

Have a look at git bup which is a Git extension to smartly store large binaries in a Git repository.

You'd want to have it as a submodule, but you won't have to worry about the repository getting hard to handle. One of their sample use cases is storing VM images in Git.

I haven't actually seen better compression rates, but my repositories don't have really large binaries in them.

Your mileage may vary.

For one matched character replace, use str_replace:

$string = str_replace(' ', '_', $string);

For all matched character replace, use preg_replace:

$string = preg_replace('/\s+/', '_', $string);

No.

Depending on your build environment (you don't specify), you may find that it works in exactly the way that you want.

However, there are many environments (both IDEs and a lot of hand crafted Makefiles) that expect to compile *.c - if that happens you will probably end up with linker errors due to duplicate symbols.

As a rule this practice should be avoided.

If you absolutely must #include source (and generally it should be avoided), use a different file suffix for the file.

You can check the total number of arguments which are passed in command line with "$#" Say for Example my shell script name is hello.sh

sh hello.sh hello-world
# I am passing hello-world as argument in command line which will b considered as 1 argument 
if [ $# -eq 1 ] 
then
    echo $1
else
    echo "invalid argument please pass only one argument "
fi

Output will be hello-world

Customize the initial branch name for new projects within a group

When creating a new Git repository, the first branch created is named master by default.

In coordination with the Git project, broader community, and other Git vendors, GitLab has been listening to the development community’s feedback on determining a more descriptive and inclusive name for the default branch, and is now offering users options to change the name of the default branch name for their repositories.

Previously, we shipped the ability to customize the initial branch name at the instance-level and as part of 13.6, GitLab now allows group administrators to configure the default branch name for new repositories created through the GitLab interface.

See Documentation and Issue.

GitLab 13.9 (Feb 2021) details:

Git default branch name change

Every Git repository has an initial branch. It’s the first branch to be created automatically when you create a new repository.
By default, this initial branch is named master.

Git version 2.31.0 (scheduled for release March 15, 2021) will change the default branch name in Git from master to main.

In coordination with the Git project and the broader community, GitLab will be changing the default branch name for new projects on both our SaaS (GitLab.com) and self-managed offerings starting with GitLab 14.0.
This will not affect existing projects.

For more information, see the related epic and the Git mailing list discussion.

I wrapped mp3 decoder library and made it available for .net developers. You can find it here:

http://sourceforge.net/projects/mpg123net/

Included are the samples to convert mp3 file to PCM, and read ID3 tags.

def LongestEntry(lstName):
  totalEntries = len(lstName)
  currentEntry = 0
  longestLength = 0
  while currentEntry < totalEntries:
    thisEntry = len(str(lstName[currentEntry]))
    if int(thisEntry) > int(longestLength):
      longestLength = thisEntry
      longestEntry = currentEntry
    currentEntry += 1
  return longestLength

I realize this is pretty late, but I had a similar problem and I figured I'd post what worked for me. I used the iconv utility (e.g., "iconv file.pcl -f UTF-8 -t ISO-8859-1 -c"). The "-c" option skips characters that can't be translated.

May be?

result.map(&:attributes)

If you need symbols keys:

result.map { |r| r.attributes.symbolize_keys }

Since it is a HashSet you will need to override hashCode and equals methods. http://preciselyconcise.com/java/collections/d_set.php has an example explaining how to implement hashCode and equals methods

Well, REST by design is stateless. By adding session (or anything else of that kind) you are making it stateful and defeating any purpose of having a RESTful API.

The whole idea of RESTful service is that every resource is uniquely addressable using a universal syntax for use in hypermedia links and each HTTP request should carry enough information by itself for its recipient to process it to be in complete harmony with the stateless nature of HTTP".

So whatever you are trying to do with Web API here, should most likely be re-architectured if you wish to have a RESTful API.

With that said, if you are still willing to go down that route, there is a hacky way of adding session to Web API, and it's been posted by Imran here http://forums.asp.net/t/1780385.aspx/1

Code (though I wouldn't really recommend that):

public class MyHttpControllerHandler
  : HttpControllerHandler, IRequiresSessionState
{
    public MyHttpControllerHandler(RouteData routeData): base(routeData)
    { }
}

public class MyHttpControllerRouteHandler : HttpControllerRouteHandler
{
    protected override IHttpHandler GetHttpHandler(RequestContext requestContext)
    {
        return new MyHttpControllerHandler(requestContext.RouteData);
    }
}

public class ValuesController : ApiController
{
   public string GET(string input)
   {
       var session = HttpContext.Current.Session;
       if (session != null)
       {
           if (session["Time"] == null)
           {
               session["Time"] = DateTime.Now;
           }
           return "Session Time: " + session["Time"] + input;
       }
       return "Session is not availabe" + input;
    }
}

and then add the HttpControllerHandler to your API route:

route.RouteHandler = new MyHttpControllerRouteHandler();

Or search for 'word wrap' in the Quick Launch box.

Known issues:

If you're familiar with word wrap in Notepad++, Sublime Text, or Visual Studio Code, be aware of the following issues where Visual Studio behaves differently to other editors:

1. Triple click doesn't select whole line
2. Cut command doesn't delete whole line
3. Pressing End key twice does not move cursor to end of line

Unfortunately these bugs have been closed "lower priority". If you'd like these bugs fixed, please vote for the feature request Fix known issues with word wrap.

You need to update the output of json.load with a_dict and then dump the result. And you cannot append to the file but you need to overwrite it.

After I removed

\usepackage{fontspec}% font selecting commands 
\usepackage{xunicode}% unicode character macros 
\usepackage{xltxtra} % some fixes/extras 

it seems to have worked "correctly".

It may be worth noting that the headers and footers only appear from page 2 onwards. Although I've tried the fix for this given in the fancyhdr documentation, I can't get it to work either.

You can use CSS white-space Property to achieve this.

white-space: nowrap

This also happens if you are trying to write a file, but your path is a folder.

This can happen easily by mistake.

To defend against that, use:

import os

path = r"my/path/to/file.txt"
assert os.path.isfile(path)
with open(path, "r") as f:
    pass

The assertion will fail if your path is actually a folder.

You can change the eclipse tomcat server configuration. Open the server view, double click on you server to open server configuration. Then click to activate "Publish module contents to separate XML files". Finally, restart your server, the message must disappear.

1. use single quotes for strings
2. do NOT put single quotes around table names(use ` instead)
3. do NOT put single quotes around numbers (you can, but it's harder to read)
4. do NOT put AND between ORDER BY and LIMIT
5. do NOT put = between ORDER BY, LIMIT keywords and condition

So you query will look like:

SELECT post_datetime 
FROM post 
WHERE type = 'published' 
ORDER BY post_datetime DESC 
LIMIT 3

I solved this way

class MyOnClickListener implements View.OnClickListener {
        @Override
        public void onClick(View v) {

            int itemPosition = mRecyclerView.getChildAdapterPosition(v);

            myResult = results.get(itemPosition);


        }
    }

And in the adapter

@Override
        public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,
                                                       int viewType) {            
            View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_wifi, parent, false);
            v.setOnClickListener(new MyOnClickListener());
            ViewHolder vh = new ViewHolder(v);
            return vh;
        }

This worked for me

cp /usr/local/lib/python3.5/configparser.py /usr/local/lib/python3.5/ConfigParser.py

Marc's answer got me most of the way to what I needed, but I had to go with patIndex rather than charIndex because sometimes characters other than spaces mark the ends of my data's words. Here I'm using '%[ /-]%' to look for space, slash, or dash.

Select race_id, race_description
    , Case patIndex ('%[ /-]%', LTrim (race_description))
        When 0 Then LTrim (race_description)
        Else substring (LTrim (race_description), 1, patIndex ('%[ /-]%', LTrim (race_description)) - 1)
    End race_abbreviation
from tbl_races

Results...

race_id  race_description           race_abbreviation
-------  -------------------------  -----------------
1        White                      White
2        Black or African American  Black
3        Hispanic/Latino            Hispanic

Caveat: this is for a small data set (US federal race reporting categories); I don't know what would happen to performance when scaled up to huge numbers.

Simply call InetAddress.getByName(String host) passing in your textual IP address.

From the javadoc: The host name can either be a machine name, such as "java.sun.com", or a textual representation of its IP address.

InetAddress javadoc

As of January 2020 and Xcode 11.3.1 -

• Open Xcode
• Open Xcode Preferences (Xcode->Preferences or Cmd-,)
• Click on Accounts
• At the left, click on your developer ID
• At the bottom right, click on Manage Certificates...
• In the lower left corner, click the arrow to the right of the + (plus)
• Select Apple Distribution from the menu

Xcode will automatically create an Apple Distribution certificate, install it in Keychain Access, and update Xcode's signing information

(Note: the single Apple Distribution certificate is now provided instead of the previous iOS Distribution certificate and equivalents.)

The official Jenkins documentation only mentions single line commands like the following:

// Declarative //

and (see)

pipeline {
    /* insert Declarative Pipeline here */
}

The syntax of the Jenkinsfile is based on Groovy so it is also possible to use groovy syntax for comments. Quote:

/* a standalone multiline comment
   spanning two lines */
println "hello" /* a multiline comment starting
                   at the end of a statement */
println 1 /* one */ + 2 /* two */

or

/**
 * such a nice comment
 */

If you are using NGINX over linux and want a pure bash/html, you can add a mask on your template and pipe the requests to use the sed command to do a replace by using a regullar expression.

Anyway I would rather have a bash script that takes from a templates folder and generate the final HTML.

//HashSet allows only the unique values to the list
HashSet<int> uniqueList = new HashSet<int>();

var a = uniqueList.Add(1);
var b = uniqueList.Add(2);
var c = uniqueList.Add(3);
var d = uniqueList.Add(2); // should not be added to the list but will not crash the app

//Dictionary allows only the unique Keys to the list, Values can be repeated
Dictionary<int, string> dict = new Dictionary<int, string>();

dict.Add(1,"Happy");
dict.Add(2, "Smile");
dict.Add(3, "Happy");
dict.Add(2, "Sad"); // should be failed // Run time error "An item with the same key has already been added." App will crash

//Dictionary allows only the unique Keys to the list, Values can be repeated
Dictionary<string, int> dictRev = new Dictionary<string, int>();

dictRev.Add("Happy", 1);
dictRev.Add("Smile", 2);
dictRev.Add("Happy", 3); // should be failed // Run time error "An item with the same key has already been added." App will crash
dictRev.Add("Sad", 2);
