Swift 5 Very Easy way

//MARK:- First you need to encoded your arr or what ever object you want to save in UserDefaults
//in my case i want to save Picture (NMutableArray) in the User Defaults in
//in this array some objects are UIImage & Strings

//first i have to encoded the NMutableArray 
let encodedData = NSKeyedArchiver.archivedData(withRootObject: yourArrayName)
//MARK:- Array save in UserDefaults
defaults.set(encodedData, forKey: "YourKeyName")

//MARK:- When you want to retreive data from UserDefaults
let decoded  = defaults.object(forKey: "YourKeyName") as! Data
yourArrayName = NSKeyedUnarchiver.unarchiveObject(with: decoded) as! NSMutableArray

//MARK: Enjoy this arrry "yourArrayName"

You need to give height for the parent element too! Check out this fiddle.

CSS:

html, body {height: 100%;}

#content, .container-fluid, .span9
{
    border: 1px solid #000;
    overflow-y:auto;
    height:100%;
}?

JavaScript (using jQuery) Way:

$(document).ready(function(){
    $(window).resize(function(){
        $(".fullheight").height($(document).height());
    });
});

An easy way for this is:

    int character = 'a';

If you print "character", you get 97.

NOTE: This answer is from 2011. It was a really good answer back then, but as of 2015, native HTML properties are supported by most browsers, so there's (usually) no need to implement such custom logic in JS. See Edi's answer and the docs.

Before the file is uploaded, you can check the file's extension using Javascript, and prevent the form being submitted if it doesn't match. The name of the file to be uploaded is stored in the "value" field of the form element.

Here's a simple example that only allows files that end in ".gif" to be uploaded:

<script type="text/javascript">
    function checkFile() {
        var fileElement = document.getElementById("uploadFile");
        var fileExtension = "";
        if (fileElement.value.lastIndexOf(".") > 0) {
            fileExtension = fileElement.value.substring(fileElement.value.lastIndexOf(".") + 1, fileElement.value.length);
        }
        if (fileExtension.toLowerCase() == "gif") {
            return true;
        }
        else {
            alert("You must select a GIF file for upload");
            return false;
        }
    }
</script>

<form action="upload.aspx" enctype="multipart/form-data" onsubmit="return checkFile();">
    <input name="uploadFile" id="uploadFile" type="file" />

    <input type="submit" />
</form>

However, this method is not foolproof. Sean Haddy is correct that you always want to check on the server side, because users can defeat your Javascript checking by turning off javascript, or editing your code after it arrives in their browser. Definitely check server-side in addition to the client-side check. Also I recommend checking for size server-side too, so that users don't crash your server with a 2 GB file (there's no way that I know of to check file size on the client side without using Flash or a Java applet or something).

However, checking client side before hand using the method I've given here is still useful, because it can prevent mistakes and is a minor deterrent to non-serious mischief.

There are two types of LinearSegmentedColormaps. In some, the _segmentdata is given explicitly, e.g., for jet:

>>> cm.jet._segmentdata
{'blue': ((0.0, 0.5, 0.5), (0.11, 1, 1), (0.34, 1, 1), (0.65, 0, 0), (1, 0, 0)), 'red': ((0.0, 0, 0), (0.35, 0, 0), (0.66, 1, 1), (0.89, 1, 1), (1, 0.5, 0.5)), 'green': ((0.0, 0, 0), (0.125, 0, 0), (0.375, 1, 1), (0.64, 1, 1), (0.91, 0, 0), (1, 0, 0))}

For rainbow, _segmentdata is given as follows:

>>> cm.rainbow._segmentdata
{'blue': <function <lambda> at 0x7fac32ac2b70>, 'red': <function <lambda> at 0x7fac32ac7840>, 'green': <function <lambda> at 0x7fac32ac2d08>}

We can find the functions in the source of matplotlib, where they are given as

_rainbow_data = {
        'red': gfunc[33],   # 33: lambda x: np.abs(2 * x - 0.5),
        'green': gfunc[13], # 13: lambda x: np.sin(x * np.pi),
        'blue': gfunc[10],  # 10: lambda x: np.cos(x * np.pi / 2)
}

Everything you want is already done in matplotlib, just call cm.revcmap, which reverses both types of segmentdata, so

cm.revcmap(cm.rainbow._segmentdata)

should do the job - you can simply create a new LinearSegmentData from that. In revcmap, the reversal of function based SegmentData is done with

def _reverser(f):
    def freversed(x):
        return f(1 - x)
    return freversed

while the other lists are reversed as usual

valnew = [(1.0 - x, y1, y0) for x, y0, y1 in reversed(val)] 

So actually the whole thing you want, is

def reverse_colourmap(cmap, name = 'my_cmap_r'):
     return mpl.colors.LinearSegmentedColormap(name, cm.revcmap(cmap._segmentdata)) 

Just convert the text explicitly to string using str(). Worked for me.

Use this:

ALLOWED_HOSTS =  ['localhost', '127.0.0.1']

If you are using Google's Places API, this is how you can get country and city from the place object using Javascript:

function getCityAndCountry(location) {
  var components = {};
  for(var i = 0; i < location.address_components.length; i++) {
    components[location.address_components[i].types[0]] = location.address_components[i].long_name;
  }

  if(!components['country']) {
    console.warn('Couldn\'t extract country');
    return false;
  }

  if(components['locality']) {
    return [components['locality'], components['country']];
  } else if(components['administrative_area_level_1']) {
    return [components['administrative_area_level_1'], components['country']];
  } else {
    console.warn('Couldn\'t extract city');
    return false;
  }
}

Its been a year asking this question but still for someone.

While declaring the UITapGestureRecognizer on a particular view assign the tag as

UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(gestureHandlerMethod:)];
[yourGestureEnableView addGestureRecognizer:tapRecognizer];
yourGestureEnableView.tag=2;

and in your handler do like this

-(void)gestureHandlerMethod:(UITapGestureRecognizer*)sender {
    if(sender.view.tag == 2) {
        // do something here
    }
}

See the following sample code on how to Build a basic Keras Neural Net Model, save Model (JSON) & Weights (HDF5) and load them:

# create model
model = Sequential()
model.add(Dense(X.shape[1], input_dim=X.shape[1], activation='relu')) #Input Layer
model.add(Dense(X.shape[1], activation='relu')) #Hidden Layer
model.add(Dense(output_dim, activation='softmax')) #Output Layer

# Compile & Fit model
model.compile(loss='binary_crossentropy', optimizer='adam', metrics=['accuracy'])
model.fit(X,Y,nb_epoch=5,batch_size=100,verbose=1)    

# serialize model to JSON
model_json = model.to_json()
with open("Data/model.json", "w") as json_file:
    json_file.write(simplejson.dumps(simplejson.loads(model_json), indent=4))

# serialize weights to HDF5
model.save_weights("Data/model.h5")
print("Saved model to disk")

# load json and create model
json_file = open('Data/model.json', 'r')
loaded_model_json = json_file.read()
json_file.close()
loaded_model = model_from_json(loaded_model_json)

# load weights into new model
loaded_model.load_weights("Data/model.h5")
print("Loaded model from disk")

# evaluate loaded model on test data 
# Define X_test & Y_test data first
loaded_model.compile(loss='binary_crossentropy', optimizer='adam', metrics=['accuracy'])
score = loaded_model.evaluate(X_test, Y_test, verbose=0)
print ("%s: %.2f%%" % (loaded_model.metrics_names[1], score[1]*100))

Summary:

parseInt():

• Takes a string as a first argument, the radix (An integer which is the base of a numeral system e.g. decimal 10 or binary 2) as a second argument
• The function returns a integer number, if the first character cannot be converted to a number NaN will be returned.
• If the parseInt() function encounters a non numerical value, it will cut off the rest of input string and only parse the part until the non numerical value.
• If the radix is undefined or 0, JS will assume the following:
  • If the input string begins with "0x" or "0X", the radix is 16 (hexadecimal), the remainder of the string is parsed into a number.
  • If the input value begins with a 0 the radix can be either 8 (octal) or 10 (decimal). Which radix is chosen is depending on JS engine implementation. ES5 specifies that 10 should be used then. However, this is not supported by all browsers, therefore always specify radix if your numbers can begin with a 0.
  • If the input value begins with any number, the radix will be 10

Number():

• The Number() constructor can convert any argument input into a number. If the Number() constructor cannot convert the input into a number, NaN will be returned.
• The Number() constructor can also handle hexadecimal number, they have to start with 0x.

Example:

console.log(parseInt('0xF', 16));  // 15_x000D_
_x000D_
// z is no number, it will only evaluate 0xF, therefore 15 is logged_x000D_
console.log(parseInt('0xFz123', 16));_x000D_
_x000D_
// because the radix is 10, A is considered a letter not a number (like in Hexadecimal)_x000D_
// Therefore, A will be cut off the string and 10 is logged_x000D_
console.log(parseInt('10A', 10));  // 10_x000D_
_x000D_
// first character isnot a number, therefore parseInt will return NaN_x000D_
console.log(parseInt('a1213', 10));_x000D_
_x000D_
_x000D_
console.log('\n');_x000D_
_x000D_
_x000D_
// start with 0X, therefore Number will interpret it as a hexadecimal value_x000D_
console.log(Number('0x11'));_x000D_
_x000D_
// Cannot be converted to a number, NaN will be returned, notice that_x000D_
// the number constructor will not cut off a non number part like parseInt does_x000D_
console.log(Number('123A'));_x000D_
_x000D_
// scientific notation is allowed_x000D_
console.log(Number('152e-1'));  // 15.21

Geocoding through Javascript:
https://developers.google.com/maps/documentation/javascript/geocoding

The other option for using PHP scripts sans extension is

Options +MultiViews

Or even just following in the directories .htaccess:

DefaultType application/x-httpd-php

The latter allows having all filenames without extension script being treated as PHP scripts. While MultiViews makes the webserver look for alternatives, when just the basename is provided (there's a performance hit with that however).

Use curl instead of file_get_contents:

$address = "India+Panchkula";
$url = "http://maps.google.com/maps/api/geocode/json?address=$address&sensor=false&region=India";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_PROXYPORT, 3128);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$response = curl_exec($ch);
curl_close($ch);
$response_a = json_decode($response);
echo $lat = $response_a->results[0]->geometry->location->lat;
echo "<br />";
echo $long = $response_a->results[0]->geometry->location->lng;

Today, in Office 365, Excel has so called 'array functions'. The filter function does exactly what you want. No need to use CTRL+SHIFT+ENTER anymore, a simple enter will suffice.

In Office 365, your problem would be simply solved by using:

=VLOOKUP(A3, FILTER(A2:C6, B2:B6="B"), 3, FALSE)

TL;DR; If you're still having trouble after restarting apache or nginx, also try restarting the php-fpm service.

The answers here don't always satisfy the requirement to force a reload of the php.ini file. On numerous occasions I've taken these steps to be rewarded with no update, only to find the solution I need after also restarting the php-fpm service. So if restarting apache or nginx doesn't trigger a php.ini update although you know the files are updated, try restarting php-fpm as well.

To restart the service:

Note: prepend sudo if not root

Using SysV Init scripts directly:

/etc/init.d/php-fpm restart        # typical
/etc/init.d/php5-fpm restart       # debian-style
/etc/init.d/php7.0-fpm restart     # debian-style PHP 7

Using service wrapper script

service php-fpm restart        # typical
service php5-fpm restart       # debian-style
service php7.0-fpm restart.    # debian-style PHP 7

Using Upstart (e.g. ubuntu):

restart php7.0-fpm         # typical (ubuntu is debian-based) PHP 7
restart php5-fpm           # typical (ubuntu is debian-based)
restart php-fpm            # uncommon

Using systemd (newer servers):

systemctl restart php-fpm.service        # typical
systemctl restart php5-fpm.service       # uncommon
systemctl restart php7.0-fpm.service     # uncommon PHP 7

Or whatever the equivalent is on your system.

The above commands taken directly from this server fault answer

In javascript there are no block-level scopes only function-level scopes:

Read this article about javaScript Scoping and Hoisting.

See how I debugged your code:

var deferred = $q.defer();
deferred.count = i;

console.log(deferred.count); // 0,1,2,3,4,5 --< all deferred objects

// some code

.success(function(data){
   console.log(deferred.count); // 5,5,5,5,5,5 --< only the last deferred object
   deferred.resolve(data);
})

• When you write var deferred= $q.defer(); inside a for loop it's hoisted to the top of the function, it means that javascript declares this variable on the function scope outside of the for loop.
• With each loop, the last deferred is overriding the previous one, there is no block-level scope to save a reference to that object.
• When asynchronous callbacks (success / error) are invoked, they reference only the last deferred object and only it gets resolved, so $q.all is never resolved because it still waits for other deferred objects.
• What you need is to create an anonymous function for each item you iterate.
• Since functions do have scopes, the reference to the deferred objects are preserved in a closure scope even after functions are executed.
• As #dfsq commented: There is no need to manually construct a new deferred object since $http itself returns a promise.

Solution with angular.forEach:

Here is a demo plunker: http://plnkr.co/edit/NGMp4ycmaCqVOmgohN53?p=preview

UploadService.uploadQuestion = function(questions){

    var promises = [];

    angular.forEach(questions , function(question) {

        var promise = $http({
            url   : 'upload/question',
            method: 'POST',
            data  : question
        });

        promises.push(promise);

    });

    return $q.all(promises);
}

My favorite way is to use Array#map:

Here is a demo plunker: http://plnkr.co/edit/KYeTWUyxJR4mlU77svw9?p=preview

UploadService.uploadQuestion = function(questions){

    var promises = questions.map(function(question) {

        return $http({
            url   : 'upload/question',
            method: 'POST',
            data  : question
        });

    });

    return $q.all(promises);
}

The "!" sign is the key element. If you have a cell object (like "mycell" in following code sample) and link a cell to this object you must pay attention to ! element.

You must do something like this:

.Cells(i, 2).Hyperlinks.Add Anchor:=.Range(Cells(i, 2).Address), Address:="", _
     SubAddress:= "'" & ws.Name & "'" & _
     "!" & mycell.Address

Use split and map function:

var str = "123, 124, 234,252";
var arr = str.split(",");
arr = arr.map(function (val) { return +val + 1; });

Notice +val - string is casted to a number.

Or shorter:

var str = "123, 124, 234,252";
var arr = str.split(",").map(function (val) { return +val + 1; });

edit 2015.07.29

Today I'd advise against using + operator to cast variable to a number. Instead I'd go with a more explicit but also more readable Number call:

var str = "123, 124, 234,252";_x000D_
var arr = str.split(",").map(function (val) {_x000D_
  return Number(val) + 1;_x000D_
});_x000D_
console.log(arr);

edit 2017.03.09

ECMAScript 2015 introduced arrow function so it could be used instead to make the code more concise:

var str = "123, 124, 234,252";_x000D_
var arr = str.split(",").map(val => Number(val) + 1);_x000D_
console.log(arr);

Use these libraries:

import java.util.LinkedHashMap;
import java.util.Map;

The code:

  public static String RomanNumerals(int Int) {
    LinkedHashMap<String, Integer> roman_numerals = new LinkedHashMap<String, Integer>();
    roman_numerals.put("M", 1000);
    roman_numerals.put("CM", 900);
    roman_numerals.put("D", 500);
    roman_numerals.put("CD", 400);
    roman_numerals.put("C", 100);
    roman_numerals.put("XC", 90);
    roman_numerals.put("L", 50);
    roman_numerals.put("XL", 40);
    roman_numerals.put("X", 10);
    roman_numerals.put("IX", 9);
    roman_numerals.put("V", 5);
    roman_numerals.put("IV", 4);
    roman_numerals.put("I", 1);
    String res = "";
    for(Map.Entry<String, Integer> entry : roman_numerals.entrySet()){
      int matches = Int/entry.getValue();
      res += repeat(entry.getKey(), matches);
      Int = Int % entry.getValue();
    }
    return res;
  }
  public static String repeat(String s, int n) {
    if(s == null) {
        return null;
    }
    final StringBuilder sb = new StringBuilder();
    for(int i = 0; i < n; i++) {
        sb.append(s);
    }
    return sb.toString();
  }

Testing the code:

  for (int i = 1;i<256;i++) {
    System.out.println("i="+i+" -> "+RomanNumerals(i));
  }

The output:

You can get around this problem by writing a custom function that uses curl, as in:

function file_get_contents_curl( $url ) {

  $ch = curl_init();

  curl_setopt( $ch, CURLOPT_AUTOREFERER, TRUE );
  curl_setopt( $ch, CURLOPT_HEADER, 0 );
  curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 );
  curl_setopt( $ch, CURLOPT_URL, $url );
  curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, TRUE );

  $data = curl_exec( $ch );
  curl_close( $ch );

  return $data;

}

Then just use file_get_contents_curl instead of file_get_contents whenever you're calling a url that begins with https.

This code is to solve our problem to set unique key for existing table

I've added jsperf test to see the speed difference for different approaches to get the first child (total 1000+ children)

given, notif = $('#foo')

jQuery ways:

1. $(":first-child", notif) - 4,304 ops/sec - fastest
2. notif.children(":first") - 653 ops/sec - 85% slower
3. notif.children()[0] - 1,416 ops/sec - 67% slower

Native ways:

4. JavaScript native' ele.firstChild - 4,934,323 ops/sec (all the above approaches are 100% slower compared to firstChild)
5. Native DOM ele from jQery: notif[0].firstChild - 4,913,658 ops/sec

So, first 3 jQuery approaches are not recommended, at least for first-child (I doubt that would be the case with many other too). If you have a jQuery object and need to get the first-child, then get the native DOM element from the jQuery object, using array reference [0] (recommended) or .get(0) and use the ele.firstChild. This gives the same identical results as regular JavaScript usage.

all tests are done in Chrome Canary build v15.0.854.0

I'm using mongojs, and i have this example:

db.users.findOne({'_id': db.ObjectId(user_id)  }, function(err, user) {
   if(err == null && user != null){
      user._id.toHexString(); // I convert the objectId Using toHexString function.
   }
})

I hope this help.

Another OOP method for DateTime with setting the exact hour:

$yesterday = new DateTime("yesterday 09:00:59", new DateTimeZone('Europe/London'));
echo $yesterday->format('Y-m-d H:i:s') . "\n";

Another perspective for doing it on Linux... here is how to do it so that the resulting single file contains the decrypted private key so that something like HAProxy can use it without prompting you for passphrase.

openssl pkcs12 -in file.pfx -out file.pem -nodes

Then you can configure HAProxy to use the file.pem file.

This is an EDIT from previous version where I had these multiple steps until I realized the -nodes option just simply bypasses the private key encryption. But I'm leaving it here as it may just help with teaching.

openssl pkcs12 -in file.pfx -out file.nokey.pem -nokeys
openssl pkcs12 -in file.pfx -out file.withkey.pem
openssl rsa -in file.withkey.pem -out file.key
cat file.nokey.pem file.key > file.combo.pem

1. The 1st step prompts you for the password to open the PFX.
2. The 2nd step prompts you for that plus also to make up a passphrase for the key.
3. The 3rd step prompts you to enter the passphrase you just made up to store decrypted.
4. The 4th puts it all together into 1 file.

Then you can configure HAProxy to use the file.combo.pem file.

The reason why you need 2 separate steps where you indicate a file with the key and another without the key, is because if you have a file which has both the encrypted and decrypted key, something like HAProxy still prompts you to type in the passphrase when it uses it.

Here's a module for calculating SHA1 hashes that is usable for Excel formulas eg. '=SHA1HASH("test")'. To use it, make a new module called 'module_sha1' and copy and paste it all in. This is based on some VBA code from http://vb.wikia.com/wiki/SHA-1.bas, with changes to support passing it a string, and executable from formulas in Excel cells.

With the forcats package from the tidyverse this is easy, too.

mutate(dat, x = fct_recode(x, "B" = "A"))

That happened to me too, because I was trying to get an IEnumerable but the response had a single value. Please try to make sure it's a list of data in your response. The lines I used (for api url get) to solve the problem are like these:

HttpResponseMessage response = await client.GetAsync("api/yourUrl");

if (response.IsSuccessStatusCode)
{
    IEnumerable<RootObject> rootObjects =
        awaitresponse.Content.ReadAsAsync<IEnumerable<RootObject>>();

    foreach (var rootObject in rootObjects)
    {
        Console.WriteLine(
            "{0}\t${1}\t{2}",
            rootObject.Data1, rootObject.Data2, rootObject.Data3);
    }

    Console.ReadLine();
}

Hope It helps.

I think it's better to use the Microsoft.VisualBasic.FileIO.TextFieldParser Class if you're working with comma separated values text files.

you can split using a third party software http://www.hjsplit.org/, for example give yours input that could be upto 9GB and then split, in my case I split 10 MB each

Many ways this can be achieved.

Simple approach should be taking Substring of an input string.

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

Another approach using Regular Expression to extract last 3 characters.

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

Working Demo

Requests doesn't have an equivalent to Urlib2's read().

>>> import requests
>>> response = requests.get("http://www.google.com")
>>> print response.content
'<!doctype html><html itemscope="" itemtype="http://schema.org/WebPage"><head>....'
>>> print response.content == response.text
True

It looks like the POST request you are making is returning no content. Which is often the case with a POST request. Perhaps it set a cookie? The status code is telling you that the POST succeeded after all.

Edit for Python 3:

Python now handles data types differently. response.content returns a sequence of bytes (integers that represent ASCII) while response.text is a string (sequence of chars).

Thus,

>>> print response.content == response.text
False

>>> print str(response.content) == response.text
True

Try this,

<?php
$arr1=array('result1'=>'abcd','result2'=>'efg'); 
$arr2=array('result1'=>'hijk','result2'=>'lmn'); 
$arr3=array($arr1,$arr2); 
print (json_encode($arr3)); 
?>

@see is useful for information about related methods/classes in an API. It will produce a link to the referenced method/code on the documentation. Use it when there is related code that might help the user understand how to use the API.

Previous answers explained it well, I am adding my answer to help in case you are dealing with a remote password protected database

mongodump --host xx.xxx.xx.xx --port 27017 --db your_db_name --username your_user_name --password your_password --out /target/folder/path

There is one last language feature where the distinction is important. Consider the following function:

def foo(*positional, **keywords):
    print "Positional:", positional
    print "Keywords:", keywords

The *positional argument will store all of the positional arguments passed to foo(), with no limit to how many you can provide.

>>> foo('one', 'two', 'three')
Positional: ('one', 'two', 'three')
Keywords: {}

The **keywords argument will store any keyword arguments:

>>> foo(a='one', b='two', c='three')
Positional: ()
Keywords: {'a': 'one', 'c': 'three', 'b': 'two'}

And of course, you can use both at the same time:

>>> foo('one','two',c='three',d='four')
Positional: ('one', 'two')
Keywords: {'c': 'three', 'd': 'four'}

These features are rarely used, but occasionally they are very useful, and it's important to know which arguments are positional or keywords.

Relative paths can be best understood if you know how Java runs the program.

There is a concept of working directory when running programs in Java. Assuming you have a class, say, FileHelper that does the IO under /User/home/Desktop/projectRoot/src/topLevelPackage/.

Depending on the case where you invoke java to run the program, you will have different working directory. If you run your program from within and IDE, it will most probably be projectRoot.

• In this case $ projectRoot/src : java topLevelPackage.FileHelper it will be src.

• In this case $ projectRoot : java -cp src topLevelPackage.FileHelper it will be projectRoot.

• In this case $ /User/home/Desktop : java -cp ./projectRoot/src topLevelPackage.FileHelper it will be Desktop.

(Assuming $ is your command prompt with standard Unix-like FileSystem. Similar correspondence/parallels with Windows system)

So, your relative path root (.) resolves to your working directory. Thus to be better sure of where to write files, it's said to consider below approach.

package topLevelPackage

import java.io.File;
import java.nio.file.Path;
import java.nio.file.Paths;

public class FileHelper {

    // Not full implementation, just barebone stub for path
    public void createLocalFile() {

        // Explicitly get hold of working directory
        String workingDir = System.getProperty("user.dir");

        Path filePath = Paths.get(workingDir+File.separator+"sampleFile.txt");

        // In case we need specific path, traverse that path, rather using . or .. 
        Path pathToProjectRoot = Paths.get(System.getProperty("user.home"), "Desktop", "projectRoot");

        System.out.println(filePath);
        System.out.println(pathToProjectRoot);

    }
}

Hope this helps.

My best result as a script:

git for-each-ref --sort=-committerdate refs/heads/ --format='%(refname:short)|%(committerdate:iso)|%(authorname)' |

var fileInput = $('#uploadCaptureInputFile');
fileInput.replaceWith(fileInput.val('').clone(true));

I want to clarify some things here for the original poster which others have alluded to but haven't really explicitly stated. When you say that you want a Unique List, that is the very definition of an Ordered Set. Some other key differences between the Set Interface and the List interface are that List allows you to specify the insert index. So, the question is do you really need the List Interface (i.e. for compatibility with a 3rd party library, etc.), or can you redesign your software to use the Set interface? You also have to consider what you are doing with the interface. Is it important to find elements by their index? How many elements do you expect in your set? If you are going to have many elements, is ordering important?

If you really need a List which just has a unique constraint, there is the Apache Common Utils class org.apache.commons.collections.list.SetUniqueList which will provide you with the List interface and the unique constraint. Mind you, this breaks the List interface though. You will, however, get better performance from this if you need to seek into the list by index. If you can deal with the Set interface, and you have a smaller data set, then LinkedHashSet might be a good way to go. It just depends on the design and intent of your software.

Again, there are certain advantages and disadvantages to each collection. Some fast inserts but slow reads, some have fast reads but slow inserts, etc. It makes sense to spend a fair amount of time with the collections documentation to fully learn about the finer details of each class and interface.

There are several ways to do this:

$collection = Mage::getModel('...')
            ->getCollection()
            ->setPageSize(20)
            ->setCurPage(1);

Will get first 20 records.

Here is the alternative and maybe more readable way:

$collection = Mage::getModel('...')->getCollection();
$collection->getSelect()->limit(20);

This will call Zend Db limit. You can set offset as second parameter.

Another way to solve with Reflection, but without marshalling:

I have this abstract helper class:

public abstract class MvcIntegrationTestUtils {

       public static MockHttpServletRequestBuilder postForm(String url,
                 Object modelAttribute, String... propertyPaths) {

              try {
                     MockHttpServletRequestBuilder form = post(url).characterEncoding(
                           "UTF-8").contentType(MediaType.APPLICATION_FORM_URLENCODED);

                     for (String path : propertyPaths) {
                            form.param(path, BeanUtils.getProperty(modelAttribute, path));
                     }

                     return form;

              } catch (Exception e) {
                     throw new RuntimeException(e);
              }
     }
}

You use it like this:

// static import (optional)
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;

// in your test method, populate your model attribute object (yes, works with nested properties)
BlogSetup bgs = new BlogSetup();
      bgs.getBlog().setBlogTitle("Test Blog");
      bgs.getUser().setEmail("[email protected]");
    bgs.getUser().setFirstName("Administrator");
      bgs.getUser().setLastName("Localhost");
      bgs.getUser().setPassword("password");

// finally put it together
mockMvc.perform(
            postForm("/blogs/create", bgs, "blog.blogTitle", "user.email",
                    "user.firstName", "user.lastName", "user.password"))
            .andExpect(status().isOk())

I have deduced it is better to be able to mention the property paths when building the form, since I need to vary that in my tests. For example, I might want to check if I get a validation error on a missing input and I'll leave out the property path to simulate the condition. I also find it easier to build my model attributes in a @Before method.

The BeanUtils is from commons-beanutils:

    <dependency>
        <groupId>commons-beanutils</groupId>
        <artifactId>commons-beanutils</artifactId>
        <version>1.8.3</version>
        <scope>test</scope>
    </dependency>

Increase the height i.e.. android:height="Some size" , it is working fine for me.

I Know this question was aked 3 years ago, but I just had the same problem, and what solved it was instead of putting:

 while (i.hasNext()) {
    // code goes here 
}

I did one iteration at the start, and then checked for condition using:

do {
   // code goes here
} while (i.hasNext());

I hope this will help some people at some stage.

This solution creates a div at the actual scrollTop and removes it after changing hash:

$('#menu a').on('click',function(){
    //your anchor event here
    var href = $(this).attr('href');
    window.location.hash = href;
    if(window.location.hash == href)return false;           
    var $jumpTo = $('body').find(href);
    $('body').append(
        $('<div>')
            .attr('id',$jumpTo.attr('id'))
            .addClass('fakeDivForHash')
            .data('realElementForHash',$jumpTo.removeAttr('id'))
            .css({'position':'absolute','top':$(window).scrollTop()})
    );
    window.location.hash = href;    
});
$(window).on('hashchange', function(){
    var $fakeDiv = $('.fakeDivForHash');
    if(!$fakeDiv.length)return true;
    $fakeDiv.data('realElementForHash').attr('id',$fakeDiv.attr('id'));
    $fakeDiv.remove();
});

optional, triggering anchor event at page load:

$('#menu a[href='+window.location.hash+']').click();

I used this code to show the dialog at the bottom of the screen:

Dialog dlg = <code to create custom dialog>;

Window window = dlg.getWindow();
WindowManager.LayoutParams wlp = window.getAttributes();

wlp.gravity = Gravity.BOTTOM;
wlp.flags &= ~WindowManager.LayoutParams.FLAG_DIM_BEHIND;
window.setAttributes(wlp);

This code also prevents android from dimming the background of the dialog, if you need it. You should be able to change the gravity parameter to move the dialog about

private void showPictureialog() {
    final Dialog dialog = new Dialog(this,
            android.R.style.Theme_Translucent_NoTitleBar);

    // Setting dialogview
    Window window = dialog.getWindow();
    window.setGravity(Gravity.CENTER);

    window.setLayout(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
    dialog.setTitle(null);
    dialog.setContentView(R.layout.selectpic_dialog);
    dialog.setCancelable(true);

    dialog.show();
}

you can customize you dialog based on gravity and layout parameters change gravity and layout parameter on the basis of your requirenment

I'm jumping in here a little late, but came across this page when pondering it myself. Of course I don't know how Facebook or Twitter justified it, but here is my own thought process for what it's worth.

In the end, I concluded that this practice is not that unsemantic (is that a word?). In fact, besides shortness and the nice association of "i is for icon," I think it's actually the most semantic choice for an icon when a straightforward <img> tag is not practical.

1. The usage is consistent with the spec.

While it may not be what the W3 mainly had in mind, it seems to me the official spec for <i> could accommodate an icon pretty easily. After all, the reply-arrow symbol is saying "reply" in another way. It expresses a technical term that may be unfamiliar to the reader and would be typically italicized. ("Here at Twitter, this is what we call a reply arrow.") And it is a term from another language: a symbolic language.

If, instead of the arrow symbol, Twitter used <i>shout out</i> or <i>[Japanese character for reply]</i> (on an English page), that would be consistent with the spec. Then why not <i>[reply arrow]</i>? (I'm talking strictly HTML semantics here, not accessibility, which I'll get to.)

As far as I can see, the only part of the spec explicitly violated by icon usage is the "span of text" phrase (when the tag doesn't contain text also). It is clear that the <i> tag is mainly meant for text, but that's a pretty small detail compared with the overall intent of the tag. The important question for this tag is not what format of content it contains, but what the meaning of that content is.

This is especially true when you consider that the line between "text" and "icon" can be almost nonexistent on websites. Text may look like more like an icon (as in the Japanese example) or an icon may look like text (as in a jpg button that says "Submit" or a cat photo with an overlaid caption) or text may be replaced or enhanced with an image via CSS. Text, image - who cares? It's all content. As long as everyone - humans with impairments, browsers with impairments, search engine spiders, and other machines of various kinds can understand that meaning, we've done our job.

So the fact that the writers of the spec didn't think (or choose) to clarify this shouldn't tie our hands from doing what makes sense and is consistent with the spirit of the tag. The <a> tag was originally intended to take the user somewhere else, but now it might pop up a lightbox. Big whoop, right? If someone had figured out how to pop up a lightbox on click before the spec caught up, they still should have used the <a> tag, not a <span>, even if it wasn't entirely consistent with the current definition - because it came the closest and was still consistent with the spirit of the tag ("something will happen when you click here"). Same deal with <i> - whatever type of thing you put inside it, or however creatively you use it, it expresses the general idea of an alternate or set-apart term.

2. The <i> tag adds semantic meaning to an icon element.

The alternative option to carry an icon class by itself is <span>, which of course has no semantic meaning whatsoever. When a machine asks the <span> what it contains, it says, "I don't know. Could be anything." But the <i> tag says, "I contain a different way of saying something than the usual way, or maybe an unfamiliar term." That's not the same as "I contain an icon," but it's a lot closer to it than <span> got!

3. Eventually, common usage makes right.

In addition to the above, it's worth considering that machine readers (whether search engine, screen reader, or whatever) may at any time begin to take into account that Facebook, Twitter, and other websites use the <i> tag for icons. They don't care about the spec as much as they care about extracting meaning from code by whatever means necessary. So they might use this knowledge of common usage to simply record that "there may be an icon here" or do something more advanced like triggering a look into the CSS for a hint to meaning, or who knows what. So if you choose to use the <i> for icons on your website, you may be providing more meaning than the spec does.

Moreover, if this usage becomes widespread, it will likely be included in the spec in the future. Then you'll be going through your code, replacing <span>s with <i>'s! So it may make sense to get on board with what seems to be the direction of the spec, especially when it doesn't clearly conflict with the current spec. Common usage tends to dictate language rules more than the other way around. If you're old enough, do you remember that "Web site" was the official spelling when the word was new? Dictionaries insisted there must be a space and Web must be capitalized. There were semantic reasons for that. But common usage said, "Whatever, that's stupid. I'm using 'website' because it's more concise and looks better." And before long, dictionaries officially acknowledged that spelling as correct.

4. So I'm going ahead and using it.

So, <i> provides more meaning to machines because of the spec, it provides more meaning to humans because we easily associate "i" with "icon", and it's only one letter long. Win! And if you make sure to include equivalent text either inside the <i> tag or right next to it (as Twitter does), then screen readers understand where to click to reply, the link is usable if CSS doesn't load, and human readers with good eyesight and a decent browser see a pretty icon. With all this in mind, I don't see the downside.

For disk space, if you have Java 6, you can use the getTotalSpace and getFreeSpace methods on File. If you're not on Java 6, I believe you can use Apache Commons IO to get some of the way there.

I don't know of any cross platform way to get CPU usage or Memory usage I'm afraid.

You can do it using clone() function of jQuery, Accepted answer is ok but i am providing alternative to it, you can use append(), but it works only if you can change html slightly as below:

$(document).ready(function(){_x000D_
    $('#clone_btn').click(function(){_x000D_
      $("#car_parent").append($("#car2").clone());_x000D_
    });_x000D_
});

.car-well{_x000D_
  border:1px solid #ccc;_x000D_
  text-align: center;_x000D_
  margin: 5px;_x000D_
  padding:3px;_x000D_
  font-weight:bold;_x000D_
}

Here is the code you are looking for in javascript. Well you know you can't convert all of the ipv6 addresses

<script>
function parseIp6(str)
{
  //init
  var ar=new Array;
  for(var i=0;i<8;i++)ar[i]=0;
  //check for trivial IPs
  if(str=="::")return ar;
  //parse
  var sar=str.split(':');
  var slen=sar.length;
  if(slen>8)slen=8;
  var j=0;
  for(var i=0;i<slen;i++){
    //this is a "::", switch to end-run mode
    if(i && sar[i]==""){j=9-slen+i;continue;}
    ar[j]=parseInt("0x0"+sar[i]);
    j++;
  }

  return ar;
}
function ipcnvfrom6(ip6)
{
  var ip6=parseIp6(ip6);
  var ip4=(ip6[6]>>8)+"."+(ip6[6]&0xff)+"."+(ip6[7]>>8)+"."+(ip6[7]&0xff);
  return ip4;
}
alert(ipcnvfrom6("::C0A8:4A07"));
</script>

Using examples mentioned here, but also help from IRC, I developed my own CPU stress testing script. It uses a subshell per thread and the endless loop technique. You can also specify the number of threads and the amount of time interactively.

#!/bin/bash
# Simple CPU stress test script

# Read the user's input
echo -n "Number of CPU threads to test: "
read cpu_threads
echo -n "Duration of the test (in seconds): "
read cpu_time

# Run an endless loop on each thread to generate 100% CPU
echo -e "\E[32mStressing ${cpu_threads} threads for ${cpu_time} seconds...\E[37m"
for i in $(seq ${cpu_threads}); do
    let thread=${i}-1
    (taskset -cp ${thread} $BASHPID; while true; do true; done) &
done

# Once the time runs out, kill all of the loops
sleep ${cpu_time}
echo -e "\E[32mStressing complete.\E[37m"
kill 0

Try with this one:

$(document).ready(function(){
  $('a').click(function(e){
     e.preventDefault();
     $("#content").load($(this).attr('href'));
  });
});

and make sure to call this library first:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js">
</script>

After reading Paul's answer, I went on digging for more information on https://dev.mysql.com/doc/refman/5.7/en/query-log.html

I found a really useful code by a person. Here's the summary of the context.

(Note: The following code is not mine)

This script is an example to keep the table clean which will help you to reduce your table size. As after a day, there will be about 180k queries of log. ( in a file, it would be 30MB per day)

You need to add an additional column (event_unix) and then you can use this script to keep the log clean... it will update the timestamp into a Unix-timestamp, delete the logs older than 1 day and then update the event_time into Timestamp from event_unix... sounds a bit confusing, but it's working great.

Commands for the new column:

SET GLOBAL general_log = 'OFF';
RENAME TABLE general_log TO general_log_temp;
ALTER TABLE `general_log_temp`
ADD COLUMN `event_unix` int(10) NOT NULL AFTER `event_time`;
RENAME TABLE general_log_temp TO general_log;
SET GLOBAL general_log = 'ON';

Cleanup script:

SET GLOBAL general_log = 'OFF';
RENAME TABLE general_log TO general_log_temp;
UPDATE general_log_temp SET event_unix = UNIX_TIMESTAMP(event_time);
DELETE FROM `general_log_temp` WHERE `event_unix` < UNIX_TIMESTAMP(NOW()) - 86400;
UPDATE general_log_temp SET event_time = FROM_UNIXTIME(event_unix);
RENAME TABLE general_log_temp TO general_log;
SET GLOBAL general_log = 'ON';

Credit goes to Sebastian Kaiser (Original writer of the code).

Hope someone will find it useful as I did.

I needed to do the same and found this thread.

I tried "tail -n +, but it just printed everything.

The more +lines worked nicely on the prompt, but it turned out it behaved totally different when run in headless mode (cronjob).

I finally wrote this myself:

skip=5
FILE="/tmp/filetoprint"
tail -n$((`cat "${FILE}" | wc -l` - skip)) "${FILE}"

I disagree with the accepted answer here by Óscar López. That answer is inaccurate!

It is NOT @JoinColumn which indicates that this entity is the owner of the relationship. Instead, it is the @ManyToOne annotation which does this (in his example).

The relationship annotations such as @ManyToOne, @OneToMany and @ManyToMany tell JPA/Hibernate to create a mapping. By default, this is done through a seperate Join Table.

@JoinColumn

The purpose of @JoinColumn is to create a join column if one does not already exist. If it does, then this annotation can be used to name the join column.

MappedBy

The purpose of the MappedBy parameter is to instruct JPA: Do NOT create another join table as the relationship is already being mapped by the opposite entity of this relationship.

Remember: MappedBy is a property of the relationship annotations whose purpose is to generate a mechanism to relate two entities which by default they do by creating a join table. MappedBy halts that process in one direction.

The entity not using MappedBy is said to be the owner of the relationship because the mechanics of the mapping are dictated within its class through the use of one of the three mapping annotations against the foreign key field. This not only specifies the nature of the mapping but also instructs the creation of a join table. Furthermore, the option to suppress the join table also exists by applying @JoinColumn annotation over the foreign key which keeps it inside the table of the owner entity instead.

So in summary: @JoinColumn either creates a new join column or renames an existing one; whilst the MappedBy parameter works collaboratively with the relationship annotations of the other (child) class in order to create a mapping either through a join table or by creating a foreign key column in the associated table of the owner entity.

To illustrate how MapppedBy works, consider the code below. If MappedBy parameter were to be deleted, then Hibernate would actually create TWO join tables! Why? Because there is a symmetry in many-to-many relationships and Hibernate has no rationale for selecting one direction over the other.

We therefore use MappedBy to tell Hibernate, we have chosen the other entity to dictate the mapping of the relationship between the two entities.

@Entity
public class Driver {
    @ManyToMany(mappedBy = "drivers")
    private List<Cars> cars;
}

@Entity
public class Cars {
    @ManyToMany
    private List<Drivers> drivers;
}

Adding @JoinColumn(name = "driverID") in the owner class (see below), will prevent the creation of a join table and instead, create a driverID foreign key column in the Cars table to construct a mapping:

@Entity
public class Driver {
    @ManyToMany(mappedBy = "drivers")
    private List<Cars> cars;
}

@Entity
public class Cars {
    @ManyToMany
    @JoinColumn(name = "driverID")
    private List<Drivers> drivers;
}

Modern C++ - Yes with lambdas!

In current versions of c++ (C++11, C++14, and C++17), you can have functions inside functions in the form of a lambda:

int main() {
    // This declares a lambda, which can be called just like a function
    auto print_message = [](std::string message) 
    { 
        std::cout << message << "\n"; 
    };

    // Prints "Hello!" 10 times
    for(int i = 0; i < 10; i++) {
        print_message("Hello!"); 
    }
}

Lambdas can also modify local variables through **capture-by-reference*. With capture-by-reference, the lambda has access to all local variables declared in the lambda's scope. It can modify and change them normally.

int main() {
    int i = 0;
    // Captures i by reference; increments it by one
    auto addOne = [&] () {
        i++; 
    };

    while(i < 10) {
        addOne(); //Add 1 to i
        std::cout << i << "\n";
    }
}

C++98 and C++03 - Not directly, but yes with static functions inside local classes

C++ doesn't support that directly.

That said, you can have local classes, and they can have functions (non-static or static), so you can get this to some extend, albeit it's a bit of a kludge:

int main() // it's int, dammit!
{
  struct X { // struct's as good as class
    static void a()
    {
    }
  };

  X::a();

  return 0;
}

However, I'd question the praxis. Everyone knows (well, now that you do, anyway :)) C++ doesn't support local functions, so they are used to not having them. They are not used, however, to that kludge. I would spend quite a while on this code to make sure it's really only there to allow local functions. Not good.

I was having such trouble managing my computer labs when the %PATH% environment variable approached 1024 characters that I wrote a Powershell script to fix it.

You can download the code here: https://gallery.technet.microsoft.com/scriptcenter/Edit-and-shorten-PATH-37ef3189

You can also use it as a simple way to safely add, remove and parse PATH entries. Enjoy.

Got a similar response with https WSDL URL using php soapClient

SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from ...

After server has been updated from PHP 5.5.9-1ubuntu4.21 >> PHP 5.5.9-1ubuntu4.23 something went wrong for my client machine osx 10.12.6 / PHP 5.6.30, but MS Web Services Clients connections could be made without issues.

Apache2's server_access.log showed no entry when i tried to load WSDL so i added 'cache_wsdl' => WSDL_CACHE_NONE to prevent client-side wsdl caching, but still got no entries. Finally i tried to load wsdl per CURL -i checked HEADERS but all seemed to be ok..

Only libxml_get_last_error() provided some insight > SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

So I added some ssl options to my call:

$contextOptions = array(
    'ssl' => array(
    'verify_peer' => false,
    'verify_peer_name' => false,
    'allow_self_signed' => true
    ));

$sslContext = stream_context_create($contextOptions);

$params =  array(
    'trace' => 1,
    'exceptions' => true,
    'cache_wsdl' => WSDL_CACHE_NONE,
    'stream_context' => $sslContext
    );

try {
    $proxy = new SoapClient( $wsdl_url, $params );
} catch (SoapFault $proxy) {
    var_dump(libxml_get_last_error());
    var_dump($proxy);
}

In my case 'allow_self_signed' => true did the trick!

The following worked for me:

1. Open the Registry Editor (press windows key, type regedit and hit Enter) .
2. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Command Processor\AutoRun and clear the values.
3. Also check HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\AutoRun.

The Python time.strftime docs say:

When used with the strptime() function, the %p directive only affects the output hour field if the %I directive is used to parse the hour.

Sure enough, changing your %H to %I makes it work.

I believe the web-cam application software which comes along with the web-cam, or you native windows webcam software can be run in a batch script(windows/dos script) after turning the web cam on(i.e. if it needs an external power supply). In the bacth script , u can add appropriate delay to capture after certain time period. And keep executing the capture command in loop.

I guess this should be possible

Hi another solution to this problem is to simply add the node nodejs binary folder to your PATH using the following command:

ln -s /usr/bin/nodejs /usr/bin/node

See NPM GitHub for better explanation

Here is a benchmark of @David Arenburg's solution there as well as a recap of some solutions posted here (@mnel, @Sven Hohenstein, @Henrik):

library(dplyr)
library(data.table)
library(microbenchmark)
library(tidyr)
library(ggplot2)

df <- mtcars
DT <- as.data.table(df)
DT_32k <- rbindlist(replicate(1e3, mtcars, simplify = FALSE))
df_32k <- as.data.frame(DT_32k)
DT_32M <- rbindlist(replicate(1e6, mtcars, simplify = FALSE))
df_32M <- as.data.frame(DT_32M)
bench <- microbenchmark(
  base_32 = aggregate(hp ~ cyl, df, function(x) length(unique(x))),
  base_32k = aggregate(hp ~ cyl, df_32k, function(x) length(unique(x))),
  base_32M = aggregate(hp ~ cyl, df_32M, function(x) length(unique(x))),
  dplyr_32 = summarise(group_by(df, cyl), count = n_distinct(hp)),
  dplyr_32k = summarise(group_by(df_32k, cyl), count = n_distinct(hp)),
  dplyr_32M = summarise(group_by(df_32M, cyl), count = n_distinct(hp)),
  data.table_32 = DT[, .(count = uniqueN(hp)), by = cyl],
  data.table_32k = DT_32k[, .(count = uniqueN(hp)), by = cyl],
  data.table_32M = DT_32M[, .(count = uniqueN(hp)), by = cyl],
  times = 10
)

Results:

I can't get to your google docs file at the moment but there are some issues with your code that I will try to address while answering

    'You said time1 doesn't change, so I left it in a singe cell.

    time1 = Range("A6").Value

    'Looping through each of our output cells.
    For Each t In Range("B7:E9") 'Change these to match your real ranges.

End Sub

EDIT

I changed you worksheet to play with (see above for the new Sub). This probably does not suite your needs directly, but hopefully it will demonstrate the conept behind what I think you want to do. Please keep in mind that this code does not follow all the coding best preactices I would recommend (e.g. validating the time is actually a TIME and not some random other data type).

     A                      B                   C                   D                  E
1    LOAD_NUMBER            1                   2                   3                  4
2    DEPARTURE_TIME_DATE    11/12/2011 19:30    11/12/2011 19:30    11/12/2011 19:30    11/12/2011 20:00                
4    Dry_Refrig 7585.1  0   10099.8 16700
6    1/4/2012 19:30

Using the sub I got this output:

    A           B             C             D             E
7   Friday      1272:00:00    1272:00:00    1272:00:00    1271:30:00

Adding file-loader npm to webpack.config.js per its official usage instruction like so:

config.module.rules.push(
    {
        test: /\.(png|jpg|gif)$/,
        use: [
            {
                loader: 'file-loader',
                options: {}
            }
        ]
    }
);

worked for me.

This is the only comprehensive and reliable way I've found to do this.

Assume you want to merge "tag_1.0" into "mybranch".

    $git checkout tag_1.0 (will create a headless branch)
    $git branch -D tagbranch (make sure this branch doesn't already exist locally)
    $git checkout -b tagbranch
    $git merge -s ours mybranch
    $git commit -am "updated mybranch with tag_1.0"
    $git checkout mybranch
    $git merge tagbranch

You could make a little Tkinter app:

import Tkinter as tk

def onKeyPress(event):
    text.insert('end', 'You pressed %s\n' % (event.char, ))

root = tk.Tk()
root.geometry('300x200')
text = tk.Text(root, background='black', foreground='white', font=('Comic Sans MS', 12))
text.pack()
root.bind('<KeyPress>', onKeyPress)
root.mainloop()

One way is to: (Assumes index column begins at A1)

MsgBox Range("A1").End(xlDown).Row

Which is looking for the 1st unoccupied cell downwards from A1 and showing you its ordinal row number.

You can select the next empty cell with:

Range("A1").End(xlDown).Offset(1, 0).Select

If you need the end of a dataset (including blanks), try: Range("A:A").SpecialCells(xlLastCell).Row

If AJAX isn't an option you can use nested data structures to simplify.

<?php
$var = array(
    'qwe' => 'asd',
    'asd' => array(
        1 => 2,
        3 => 4,
    ),
    'zxc' => 0,
);
?>
<script>var data = <?php echo json_encode($var); ?>;</script>

I had the same problem, but it turned out to be a chrome extension called hola (or Proxy SwitchySharp), that messed with the proxy settings. Removing Hola fixed the problem

Here is a working and up to date code :)

/*
* Start with rating the app
* Determine if the Play Store is installed on the device
*
* */
public void rateApp()
{
    try
    {
        Intent rateIntent = rateIntentForUrl("market://details");
        startActivity(rateIntent);
    }
    catch (ActivityNotFoundException e)
    {
        Intent rateIntent = rateIntentForUrl("https://play.google.com/store/apps/details");
        startActivity(rateIntent);
    }
}

private Intent rateIntentForUrl(String url)
{
    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(String.format("%s?id=%s", url, getPackageName())));
    int flags = Intent.FLAG_ACTIVITY_NO_HISTORY | Intent.FLAG_ACTIVITY_MULTIPLE_TASK;
    if (Build.VERSION.SDK_INT >= 21)
    {
        flags |= Intent.FLAG_ACTIVITY_NEW_DOCUMENT;
    }
    else
    {
        //noinspection deprecation
        flags |= Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET;
    }
    intent.addFlags(flags);
    return intent;
}

Put the code in the Activity you would like to call it from.
When the user clicks a button to rate the app, just call the rateApp() function.

In Eclipse:

Window -> Preferences -> Android -> Lint Error Checking.

In the list find an entry with ID = ProtectedPermission. Set the Severity to something lower than Error. This way you can still compile the project using Eclipse.

In Android Studio:

File -> Settings -> Editor -> Inspections

Under Android Lint, locate Using system app permission. Either uncheck the checkbox or choose a Severity lower than Error.

I can't comment yet but thought I'd add that if you have a UISearchController on your controller with UISearchBar as your tableHeaderView, setting the height of the first section as 0 in heightForHeaderInSection does indeed work.

I use self.tableView.contentOffset = CGPointMake(0, self.searchController.searchBar.frame.size.height); so that the search bar is hidden by default.

Result is that there is no header for the first section, and scrolling down will show the search bar right above the first row.

That is a very open apples-to-oranges type of question.

You are asking 1. the average request load for a production application 2. what is considered fast

These don't neccessarily relate.

Your average # of requests per second is determined by

a. the number of simultaneous users

b. the average number of page requests they make per second

c. the number of additional requests (i.e. ajax calls, etc)

As to what is considered fast.. do you mean how few requests a site can take? Or if a piece of hardware is considered fast if it can process xyz # of requests per second?

$ export DISPLAY=yourmachine.yourdomain.com:0.0
$ firefox &

What levi said about passing it into the constructor is correct, but you could also use an object.

I think what Veverke is trying to say is that you could easily use the delete keyword on an object to achieve the same effect.

I think you're confused by the terminology; properties are components of the object that you can use as named indices (if you want to think of it that way).

Try something like this:

var obj = {
    "bob": "dole",
    "mr.": "peabody",
    "darkwing": "duck"
};

Then, you could just do this:

delete obj["bob"];

The structure of the object would then be this:

{
    "mr.": "peabody",
    "darkwing": "duck"
}

Which has the same effect.

Here's a real world example with the use of non-minified versus minified assets in your layout.

Web.Config

<appSettings>

   <add key="Environment" value="Dev" />

 </appSettings>

Razor Template - use that var above like this:

@if (System.Configuration.ConfigurationManager.AppSettings["Environment"] == "Dev")
{    
    <link type="text/css" rel="stylesheet" href="@Url.Content("~/Content/styles/theme.css" )">    

}else{        

   <link type="text/css" rel="stylesheet" href="@Url.Content("~/Content/styles/blue_theme.min.css" )">    

}

Duplicate rows can be removed for Complex Queries by,

First storing the result to a #TempTable or @TempTableVariable

Delete from #TempTable or @TempTableVariable where your condition

Then select the rest of the data.

If need to create a row number create an identity column.

If you are using a third party library called apache commons-lang, the following solution can be useful:

Use StringUtils class of apache commons-lang :

int i = 5;
StringUtils.leftPad(String.valueOf(i), 3, "0"); // --> "005"

As StringUtils.leftPad() is faster than String.format()

This should work for you:

#example.com/page will display the contents of example.com/page.html
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.html -f
RewriteRule ^(.+)$ $1.html [L,QSA]

#301 from example.com/page.html to example.com/page
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /.*\.html\ HTTP/
RewriteRule ^(.*)\.html$ /$1 [R=301,L]

How about adding this to your pom.xml

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-annotations</artifactId>
    <version>${jackson.version}</version>
</dependency>

The gritty terminal was written to use Jsch, but with better handling and vt102 emulation. You can take a look at the code there. We use it and it works just fine.

Option 1 (via controller):

angular.controller('numCtrl', function($scope, $window) {
   $scope.num = parseInt(num , 10);
}

Option 2 (via custom filter):

app.filter('num', function() {
    return function(input) {
       return parseInt(input, 10);
    }
});

{{(num1 | num) + (num2 | num)}}

Option 3 (via expression):

Declare this first in your controller:

$scope.parseInt = parseInt;

Then:

{{parseInt(num1)+parseInt(num2)}}

Option 4 (from raina77ow)

{{(num1-0) + (num2-0)}}

You can turn on wifi : - connect usb on pc; - will show alert dialog "connect UMS mode or KIES" - do not click, do not cancel - pull notification bar and turn on wifi.

After gone throug the various post, this worked fine for me doing on IntelliJ Idea:

java -cp "./lib/*;Path to your test.class"  org.testng.TestNG testng.xml

Here is my directory structure:

/lib
  -- all jar including testng.jar
/out
  --/production/Example1/test.class
/src
 -- test.java
testing.xml

So execute by this command:

java -cp "./lib/*;C:\Users\xyz\IdeaProjects\Example1\out\production\Example1" org.testng.TestNG testng.xml

My project directory Example1 is in the path:

C:\Users\xyz\IdeaProjects\

There are many PS1 generators but ezprompt has the git status (2nd tab 'Status Elements' ) also.

PHP's getimagesize() returns an array of data. The first two items in the array are the two items you're interested in: the width and height. To get these, you would simply request the first two indexes in the returned array:

var $imagedata = getimagesize("someimage.jpg");

print "Image width  is: " . $imagedata[0];
print "Image height is: " . $imagedata[1];

For further information, see the documentation.

I agree that one shouldn't suppress warnings in classes or methods as one could overlook other, accidentally suppressed warnings. But IMHO it's absolutely reasonable to suppress a warning that affects only a single line of code.

@SuppressWarnings("unchecked")
Foo<Bar> mockFoo = mock(Foo.class);

If you want the placeholder text to be red you need to target it specifically in CSS.

Write:

input::placeholder{

I highly recommend epdb (Extended Python Debugger).

https://bitbucket.org/dugan/epdb

One thing I love about epdb for debugging Django or other Python webservers is the epdb.serve() command. This sets a trace and serves this on a local port that you can connect to. Typical use case:

I have a view that I want to go through step-by-step. I'll insert the following at the point I want to set the trace.

import epdb; epdb.serve()

Once this code gets executed, I open a Python interpreter and connect to the serving instance. I can analyze all the values and step through the code using the standard pdb commands like n, s, etc.

In [2]: import epdb; epdb.connect()
(Epdb) request
<WSGIRequest
path:/foo,
GET:<QueryDict: {}>, 
POST:<QuestDict: {}>,
...
>
(Epdb) request.session.session_key
'i31kq7lljj3up5v7hbw9cff0rga2vlq5'
(Epdb) list
 85         raise some_error.CustomError()
 86 
 87     # Example login view
 88     def login(request, username, password):
 89         import epdb; epdb.serve()
 90  ->     return my_login_method(username, password)
 91
 92     # Example view to show session key
 93     def get_session_key(request):
 94         return request.session.session_key
 95

And tons more that you can learn about typing epdb help at any time.

If you want to serve or connect to multiple epdb instances at the same time, you can specify the port to listen on (default is 8080). I.e.

import epdb; epdb.serve(4242)

>> import epdb; epdb.connect(host='192.168.3.2', port=4242)

host defaults to 'localhost' if not specified. I threw it in here to demonstrate how you can use this to debug something other than a local instance, like a development server on your local LAN. Obviously, if you do this be careful that the set trace never makes it onto your production server!

As a quick note, you can still do the same thing as the accepted answer with epdb (import epdb; epdb.set_trace()) but I wanted to highlight the serve functionality since I've found it so useful.

Old Way (pre-1.7):

$("...").attr("onclick", "").unbind("click");

New Way (1.7+):

$("...").prop("onclick", null).off("click");

(Replace ... with the selector you need.)

// use the "[attr=value]" syntax to avoid syntax errors with special characters (like "$")_x000D_
$('[id="a$id"]').prop('onclick',null).off('click');

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
_x000D_
<a id="a$id" onclick="alert('get rid of this')" href="javascript:void(0)"  class="black">Qualify</a>

The correct answer IMO depends on two things: 1. What is the purpose of the web application you want to write? You only told us that you want to write it fast, but not what you are actually trying to do. Eg. does it need a database? Is it some sort of business app (hint: maybe search for "scaffolding")? ..or a game? ..or are you just experimenting with sthg? 2. What frameworks are you most familiar with right now? What often takes most time is reading docs and figuring out how things (really) work. If you want it done quickly, stick to things you already know well.

I think you need this ..

Dim n as Integer   

For n = 5 to 17
  msgbox cells(n,3) '--> sched waste
  msgbox cells(n,4) '--> type of treatm
  msgbox format(cells(n,5),"dd/MM/yyyy") '--> Lic exp
  msgbox cells(n,6) '--> email col

This tool creates the folders with the images in them automatically for you. All you have to do is supply your image then drag the generated folders to your res folder. http://romannurik.github.io/AndroidAssetStudio/

All the best.

I'm a bit newer to Angular but what I found useful to do (and pretty simple) is I made a global script that I load onto my page before the local script with global variables that I need to access on all pages anyway. In that script, I created an object called "globalFunctions" and added the functions that I need to access globally as properties. e.g. globalFunctions.foo = myFunc();. Then, in each local script, I wrote $scope.globalFunctions = globalFunctions; and I instantly have access to any function I added to the globalFunctions object in the global script.

This is a bit of a workaround and I'm not sure it helps you but it definitely helped me as I had many functions and it was a pain adding all of them to each page.

updated for Swift 3 :

used below code to make UIButton corner round:

 yourButtonOutletName.layer.cornerRadius = 0.3 *
        yourButtonOutletName.frame.size.height

As much as people like to say "order doesn't matter its just convention" this breaks down when entering cross domain interfaces, IE transfer from C ordering to Fortran ordering or some other ordering scheme. There, precisely how your data is layed out and how shape is represented in numpy is very important.

By default, numpy uses C ordering, which means contiguous elements in memory are the elements stored in rows. You can also do FORTRAN ordering ("F"), this instead orders elements based on columns, indexing contiguous elements.

Numpy's shape further has its own order in which it displays the shape. In numpy, shape is largest stride first, ie, in a 3d vector, it would be the least contiguous dimension, Z, or pages, 3rd dim etc... So when executing:

np.zeros((2,3,4)).shape

you will get

(2,3,4)

which is actually (frames, rows, columns). doing np.zeros((2,2,3,4)).shape instead would mean (metaframs, frames, rows, columns). This makes more sense when you think of creating multidimensional arrays in C like langauges. For C++, creating a non contiguously defined 4D array results in an array [ of arrays [ of arrays [ of elements ]]]. This forces you to de reference the first array that holds all the other arrays (4th dimension) then the same all the way down (3rd, 2nd, 1st) resulting in syntax like:

double element = array4d[w][z][y][x];

In fortran, this indexed ordering is reversed (x is instead first array4d[x][y][z][w]), most contiguous to least contiguous and in matlab, it gets all weird.

Matlab tried to preserve both mathematical default ordering (row, column) but also use column major internally for libraries, and not follow C convention of dimensional ordering. In matlab, you order this way:

double element = array4d[y][x][z][w];

which deifies all convention and creates weird situations where you are sometimes indexing as if row ordered and sometimes column ordered (such as with matrix creation).

In reality, Matlab is the unintuitive one, not Numpy.

When you got:

Error: Uncaught Error: Target container is not a DOM element.

You can use DOMContentLoaded event or move your <script ...></script> tag in the bottom of your body.

The DOMContentLoaded event fires when the initial HTML document has been completely loaded and parsed, without waiting for stylesheets, images, and subframes to finish loading.

document.addEventListener("DOMContentLoaded", function(event) {
  ReactDOM.render(<App />, document.getElementById('root'));
})

Here is some code that might help you out. Strings can be treated as an array of characters

string numbers = "12345";
int[] intArray = new int[numbers.Length];
for (int i=0; i < numbers.Length; i++)
{
   intArray[i] = int.Parse(numbers[i]);
}

After= dependency is only effective when service including After= and service included by After= are both scheduled to start as part of your boot up.

Ex:

a.service
[Unit]
After=b.service

This way, if both a.service and b.service are enabled, then systemd will order b.service after a.service.

If I am not misunderstanding, what you are asking is how to start b.service when a.service starts even though b.service is not enabled.

The directive for this is Wants= or Requires= under [Unit].

website.service
[Unit]
Wants=mongodb.service
After=mongodb.service

The difference between Wants= and Requires= is that with Requires=, a failure to start b.service will cause the startup of a.service to fail, whereas with Wants=, a.service will start even if b.service fails. This is explained in detail on the man page of .unit.

I compiled a small Bash script for Mac (easily can be ported to Linux) to retrieve all CPU features and apply some of them to build TF. Im on TF master and use kinda often (couple times in a month).

export GIT_EXTERNAL_DIFF='meld $2 $5; echo >/dev/null'

then simply:

git diff

using System.IO;
using System.Text;

using (StreamWriter sw = new StreamWriter(File.Open(myfilename, FileMode.Create), Encoding.WhateverYouWant))
{    
    sw.WriteLine("my text...");     
}

An alternate way of getting your encoding:

using System.IO;
using System.Text;

using (var sw  = new StreamWriter(File.Open(@"c:\myfile.txt", FileMode.CreateNew), Encoding.GetEncoding("iso-8859-1"))) {
    sw.WriteLine("my text...");             
}

Check out the docs for the StreamWriter constructor.

Be aware that the Path is case sensitive. I tried setx PATH and it didn't work. In my case it was setx Path. Make sure your CMD run as Administrator.

setx Path "%PATH%;C:\Program Files\nodejs"

Now just restart your command prompt (or restart the PC) and the node command should be available.

I've created the following script and it worked for me just fine.

#! /bin/sh
cd $(dirname $0)
DB=$1
DBUSER=$2
DBPASSWD=$3
FILE=$DB-$(date +%F).sql
mysqldump --routines "--user=${DBUSER}"  --password=$DBPASSWD $DB > $PWD/$FILE
gzip $FILE
echo Created $PWD/$FILE*

and you call the script using command line arguments.

backupdb.sh my_db dev_user dev_password

Format with Currency format string

=Format(Fields!Price.Value, "C")

It will give you 2 decimal places with "$" prefixed.

You can find other format strings on MSDN: Adding Style and Formatting to a ReportViewer Report

Note: The MSDN article has been archived to the "VS2005_General" document, which is no longer directly accessible online. Here is the excerpt of the formatting strings referenced:

Formatting Numbers

The following table lists common .NET Framework number formatting strings.

Format string, Name

C or c Currency

D or d Decimal

E or e Scientific

F or f Fixed-point

G or g General

N or n Number

P or p Percentage

R or r Round-trip

X or x Hexadecimal

You can modify many of the format strings to include a precision specifier that defines the number of digits to the right of the

decimal point. For example, a formatting string of D0 formats the number so that it has no digits after the decimal point. You

can also use custom formatting strings, for example, #,###.

Formatting Dates

The following table lists common .NET Framework date formatting strings.

Format string, Name

d Short date

D Long date

t Short time

T Long time

f Full date/time (short time)

F Full date/time (long time)

g General date/time (short time)

G General date/time (long time)

M or m Month day

R or r RFC1123 pattern

Y or y Year month

You can also a use custom formatting strings; for example, dd/MM/yy. For more information about .NET Framework formatting strings, see Formatting Types.

As a general (see Stackblitz here: https://stackblitz.com/edit/angular-gh2rjx):

HTML

<select [(ngModel)]="selectedOption">
   <option *ngFor="let o of options">
      {{o.name}}
   </option>
</select>
<button (click)="print()">Click me</button>

<p>Selected option: {{ selectedOption }}</p>
<p>Button output: {{ printedOption }}</p>

Typescript

export class AppComponent {
  selectedOption: string;
  printedOption: string;

  options = [
    { name: "option1", value: 1 },
    { name: "option2", value: 2 }
  ]
  print() {
    this.printedOption = this.selectedOption;
  }
}

In your specific case you can use ngModel like this:

<form class="form-inline" (ngSubmit)="HelloCorp()">
     <div class="select">
         <select [(ngModel)]="corporationObj" class="form-control col-lg-8" #corporation required>
             <option *ngFor="let corporation of corporations"></option>    
         </select>
         <button type="submit" class="btn btn-primary manage">Submit</button>
     </div>
</form>

HelloCorp() {
  console.log("My input: ", corporationObj);
}

The check can be done like this:

if (!!inp.val()) {

}

and even shorter:

if (inp.val()) {

}

a.button a:hover means "a link that's being hovered over that is a child of a link with the class button".

Go instead for a.button:hover.

Instances of the image constructor are not meant to be used anywhere. You simply set the src, and the image preloads...and that's it, show's over. You can discard the object and move on.

document["pic1"].src = "XXXX/YYYY/search.png"; 

is what you should be doing. You can still use the image constructor, and perform the second action in the onload handler of your searchPic. This ensures the image is loaded before you set the src on the real img object.

Like so:

function LoadImages() {
    searchPic = new Image();
    searchPic.onload=function () {
        document["pic1"].src = "XXXX/YYYY/search.png";
    }
    searchPic.src = "XXXX/YYYY/search.png"; // This is correct and the path is correct
}

Exception#backtrace has the entire stack in it:

def do_division_by_zero; 5 / 0; end
begin
  do_division_by_zero
rescue => exception
  puts exception.backtrace
  raise # always reraise
end

(Inspired by Peter Cooper's Ruby Inside blog)

For concatenating selectors together when nesting, you need to use the parent selector (&):

.class {
    margin:20px;
    &:hover {
        color:yellow;
    }
}

I think pi has ssh server enabled by default. Mine have always worked out of the box. Depends which operating system version maybe.

Most of the time when it fails for me it is because the ip address has been changed. Perhaps you are pinging something else now? Also sometimes they just refuse to connect and need a restart.

If you don't want to use jQuery and aren't especially concerned about backwards compatibility, just use:

let element = document.getElementById(id);
element.dispatchEvent(new Event("change")); // or whatever the event type might be

See the documentation here and here.

EDIT: Depending on your setup you might want to add bubbles: true:

let element = document.getElementById(id);
element.dispatchEvent(new Event('change', { 'bubbles': true }));

Using lodash _.values(object)

_.values({"id": 1, "second": "abcd"})

[ 1, 'abcd' ]

lodash includes a whole bunch of other functions to work with arrays, objects, collections, strings, and more that you wish were built into JavaScript (and actually seem to slowly be making their way into the language).

As elements are yet ordered, you don't have to build a map, there's a fast solution :

var newarr = [arr[0]];
for (var i=1; i<arr.length; i++) {
   if (arr[i]!=arr[i-1]) newarr.push(arr[i]);
}

If your array weren't sorted, you would use a map :

var newarr = (function(arr){
  var m = {}, newarr = []
  for (var i=0; i<arr.length; i++) {
    var v = arr[i];
    if (!m[v]) {
      newarr.push(v);
      m[v]=true;
    }
  }
  return newarr;
})(arr);

Note that this is, by far, much faster than the accepted answer.

You could always do just:

a=[1,2,3]
b=['a','b']
c=[1,2,3,4]
d=[1,2,3]

a==b    #returns False
a==c    #returns False
a==d    #returns True

Change the names of your inputs:

<input name="xyz[]" value="Lorem" />
<input name="xyz[]" value="ipsum"  />
<input name="xyz[]" value="dolor" />
<input name="xyz[]" value="sit" />
<input name="xyz[]" value="amet" />

Then:

$_POST['xyz'][0] == 'Lorem'
$_POST['xyz'][4] == 'amet'

If so, that would make my life ten times easier, as I could send an indefinite amount of information through a form and get it processed by the server simply by looping through the array of items with the name "xyz".

Note that this is probably the wrong solution. Obviously, it depends on the data you are sending.

It is possible to horisontally center the div this way:

html:

<div class="container">
    <div class="inner">content</div>
</div>

css:

.container {
    left: 0;
    right: 0;
    bottom: 0; /* or top: 0, or any needed value */
    position: fixed;
    z-index: 1000; /* or even higher to prevent guarantee overlapping */
}

.inner {
    max-width: 600px; /* just for example */
    margin: 0 auto;
}

Using this way you will have always your inner block centered, in addition it can be easily turned to true responsive (in the example it will be just fluid on smaller screens), therefore no limitation in as in the question example and in the chosen answer.

rm -f .git/index

This is a simple example of a classic Order example. Each Customer can have multiple Orders, and each Order can consist of multiple OrderLines.

You create a relation by adding a foreign key column. Each Order record has a CustomerID in it, that points to the ID of the Customer. Similarly, each OrderLine has an OrderID value. This is how the database diagram looks:

In this diagram, there are actual foreign key constraints. They are optional, but they ensure integrity of your data. Also, they make the structure of your database clearer to anyone using it.

I assume you know how to create the tables themselves. Then you just need to define the relationships between them. You can of course define constraints in T-SQL (as posted by several people), but they're also easily added using the designer. Using SQL Management Studio, you can right-click the Order table, click Design (I think it may be called Edit under 2005). Then anywhere in the window that opens right-click and select Relationships.

You will get another dialog, on the right there should be a grid view. One of the first lines reads "Tables and Columns Specification". Click that line, then click again on the little [...] button that appears on the right. You will get this dialog:

The Order table should already be selected on the right. Select the Customer table on the left dropdown. Then in the left grid, select the ID column. In the right grid, select the CustomerID column. Close the dialog, and the next. Press Ctrl+S to save.

Having this constraint will ensure that no Order records can exist without an accompanying Customer record.

To effectively query a database like this, you might want to read up on JOINs.

Use

Time.now + 10.days

or even

10.days.from_now

Both definitely work. Are you sure you're in Rails and not just Ruby?

If you definitely are in Rails, where are you trying to run this from? Note that Active Support has to be loaded.

You can use SHOW:

SHOW max_connections;

This returns the currently effective setting. Be aware that it can differ from the setting in postgresql.conf as there are a multiple ways to set run-time parameters in PostgreSQL. To reset the "original" setting from postgresql.conf in your current session:

RESET max_connections;

However, not applicable to this particular setting. The manual:

This parameter can only be set at server start.

To see all settings:

SHOW ALL;

There is also pg_settings:

The view pg_settings provides access to run-time parameters of the server. It is essentially an alternative interface to the SHOW and SET commands. It also provides access to some facts about each parameter that are not directly available from SHOW, such as minimum and maximum values.

For your original request:

SELECT *
FROM   pg_settings
WHERE  name = 'max_connections';

Finally, there is current_setting(), which can be nested in DML statements:

SELECT current_setting('max_connections');

When the browser puts something in its cache, it also stores the Last-Modified or ETag header from the server.

The browser then sends a request with the If-Modified-Since or If-None-Match header, telling the server to send a 304 if the content still has that date or ETag.

The server needs some way of calculating a date-modified or ETag for each version of each resource; this typically comes from the filesystem or a separate database column.

I know this is an old thread, but I thought I throw my hat in the ring and see if I can muddy the water a little bit more :)

I found my initial struggle to understand @ModelAttribute was a result of Spring's decision to combine several annotations into one. It became clearer once I split it into several smaller annotations:

For parameter annotations, think of @ModelAttribute as the equivalent of @Autowired + @Qualifier i.e. it tries to retrieve a bean with the given name from the Spring managed model. If the named bean is not found, instead of throwing an error or returning null, it implicitly takes on the role of @Bean i.e. Create a new instance using the default constructor and add the bean to the model.

For method annotations, think of @ModelAttribute as the equivalent of @Bean + @Before, i.e. it puts the bean constructed by user's code in the model and it's always called before a request handling method.

Figuratively, I see @ModelAttribute as the following (please don't take it literally!!):

@Bean("person")
@Before
public Person createPerson(){
  return new Person();
}

@RequestMapping(...)
public xxx handlePersonRequest( (@Autowired @Qualifier("person") | @Bean("person")) Person person, xxx){
  ...
}

As you can see, Spring made the right decision to make @ModelAttribute an all-encompassing annotation; no one wants to see an annotation smorgasbord.

it seems you can directly call:

g = sns.factorplot("class", "survived", "sex",
                data=titanic, kind="bar",
                size=6, palette="muted",
               legend_out=False)

g._legend.set_bbox_to_anchor((.7, 1.1))

The solution I settled for in the end was to modify the image itself to add some spacing.

Using a background image on the li as some suggest works in a lot of cases but fails when the list is used alongside a floated image (for example to get the text to wrap around the image).

Hope this helps.

I just solved this problem very elegantly after a lot of trial and error.

Check out my blog post: http://geon.github.io/programming/2016/02/24/flexbox-full-page-web-app-layout

Basically, to make a flexbox cell scrollable, you have to make all its parents overflow: hidden;, or it will just ignore your overflow settings and make the parent larger instead.

They are enhanced variable substitutions. They modify the %N variables used in batch files. Quite useful if you're into batch programming in Windows.

%~I         - expands %I removing any surrounding quotes ("")
%~fI        - expands %I to a fully qualified path name
%~dI        - expands %I to a drive letter only
%~pI        - expands %I to a path only
%~nI        - expands %I to a file name only
%~xI        - expands %I to a file extension only
%~sI        - expanded path contains short names only
%~aI        - expands %I to file attributes of file
%~tI        - expands %I to date/time of file
%~zI        - expands %I to size of file
%~$PATH:I   - searches the directories listed in the PATH
               environment variable and expands %I to the
               fully qualified name of the first one found.
               If the environment variable name is not
               defined or the file is not found by the
               search, then this modifier expands to the
               empty string

You can find the above by running FOR /?.

Just use memcpy.

If the destination isn't big enough, strncpy won't null terminate. if the destination is huge compared to the source, strncpy just fills the destination with nulls after the string. strncpy is pointless, and unsuitable for copying strings.

strncpy is like memcpy except it fills the destination with nulls once it sees one in the source. It's absolutely useless for string operations. It's for fixed with 0 padded records.

For your first method change ws.Range("A") to ws.Range("A:A") which will search the entirety of column a, like so:

Sub Find_Bingo()

        Dim wb As Workbook
        Dim ws As Worksheet
        Dim FoundCell As Range
        Set wb = ActiveWorkbook
        Set ws = ActiveSheet

            Const WHAT_TO_FIND As String = "Bingo"

            Set FoundCell = ws.Range("A:A").Find(What:=WHAT_TO_FIND)
            If Not FoundCell Is Nothing Then
                MsgBox (WHAT_TO_FIND & " found in row: " & FoundCell.Row)
            Else
                MsgBox (WHAT_TO_FIND & " not found")
            End If
End Sub

For your second method, you are using Bingo as a variable instead of a string literal. This is a good example of why I add Option Explicit to the top of all of my code modules, as when you try to run the code it will direct you to this "variable" which is undefined and not intended to be a variable at all.

Additionally, when you are using With...End With you need a period . before you reference Cells, so Cells should be .Cells. This mimics the normal qualifying behavior (i.e. Sheet1.Cells.Find..)

Change Bingo to "Bingo" and change Cells to .Cells

With Sheet1
        Set FoundCell = .Cells.Find(What:="Bingo", After:=.Cells(1, 1), _
        LookIn:=xlValues, lookat:=xlPart, SearchOrder:=xlByRows, _
        SearchDirection:=xlNext, MatchCase:=False, SearchFormat:=False)
    End With

If Not FoundCell Is Nothing Then
        MsgBox ("""Bingo"" found in row " & FoundCell.Row)
Else
        MsgBox ("Bingo not found")
End If

Update

In my

With Sheet1
    .....
End With

The Sheet1 refers to a worksheet's code name, not the name of the worksheet itself. For example, say I open a new blank Excel workbook. The default worksheet is just Sheet1. I can refer to that in code either with the code name of Sheet1 or I can refer to it with the index of Sheets("Sheet1"). The advantage to using a codename is that it does not change if you change the name of the worksheet.

Continuing this example, let's say I renamed Sheet1 to Data. Using Sheet1 would continue to work, as the code name doesn't change, but now using Sheets("Sheet1") would return an error and that syntax must be updated to the new name of the sheet, so it would need to be Sheets("Data").

In the VB Editor you would see something like this:

Notice how, even though I changed the name to Data, there is still a Sheet1 to the left. That is what I mean by codename.

The Data worksheet can be referenced in two ways:

Debug.Print Sheet1.Name
Debug.Print Sheets("Data").Name

Both should return Data

More discussion on worksheet code names can be found here.

Arrays have a property .length that returns the number of elements.

var st =
    {
        "itema":{},
        "itemb":
        [
            {"id":"s01","cd":"c01","dd":"d01"},
            {"id":"s02","cd":"c02","dd":"d02"}
        ]
    };

st.itemb.length // 2

The most likely explanations for that error are:

1. The file you are attempting to load is not an executable file. CreateProcess requires you to provide an executable file. If you wish to be able to open any file with its associated application then you need ShellExecute rather than CreateProcess.
2. There is a problem loading one of the dependencies of the executable, i.e. the DLLs that are linked to the executable. The most common reason for that is a mismatch between a 32 bit executable and a 64 bit DLL, or vice versa. To investigate, use Dependency Walker's profile mode to check exactly what is going wrong.

Reading down to the bottom of the code, I can see that the problem is number 1.

It's almost always advisable to not use scriptlets in your JSP. They're considered bad form. Instead, try using JSTL (JSP Standard Tag Library) combined with EL (Expression Language) to run the conditional logic you're trying to do. As an added benefit, JSTL also includes other important features like looping.

Instead of:

<%String user=request.getParameter("user"); %>
<%if(user == null || user.length() == 0){
    out.print("I see! You don't have a name.. well.. Hello no name");   
}
else {%>
    <%@ include file="response.jsp" %>
<% } %>

Use:

<c:choose>
    <c:when test="${empty user}">
        I see!  You don't have a name.. well.. Hello no name
    </c:when>
    <c:otherwise>
        <%@ include file="response.jsp" %>
    </c:otherwise>
</c:choose>

Also, unless you plan on using response.jsp somewhere else in your code, it might be easier to just include the html in your otherwise statement:

<c:otherwise>
    <h1>Hello</h1>
    ${user}
</c:otherwise>

Also of note. To use the core tag, you must import it as follows:

 <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

You want to make it so the user will receive a message when the user submits a username. The easiest way to do this is to not print a message at all when the "user" param is null. You can do some validation to give an error message when the user submits null. This is a more standard approach to your problem. To accomplish this:

In scriptlet:

<% String user = request.getParameter("user");
   if( user != null && user.length() > 0 ) {
       <%@ include file="response.jsp" %>
   }
%>

In jstl:

<c:if test="${not empty user}">
    <%@ include file="response.jsp" %>
</c:if>

just change the codec to "DIVX". This codec works with all formats.

fourcc = cv2.VideoWriter_fourcc(*'DIVX')

i hope this works for you!

found it on this site, it works on me. Modify /res/values/styles.xml from:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
</style>

to:

<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">

Here's how to do it:

var myVideo = document.getElementById("my-video")    
myVideo.controls = false;

This issue here is you local git is not able to push the changes to the remote Check your remote is set correctly by

git remote -v

if it is not set properly try setting your remote as

git remote set-url origin https://[email protected]/MyRepo/project.git

Then try pushing using

git push -u origin master

Also there is a possibility of your local git has different credentials, please check that also.

Well things have changed a little bit since 2011! Now there's type hints in Python 3.5 which you can use to annotate arguments and return the type of your function. For example this:

def greeting(name):
  return 'Hello, {}'.format(name)

can now be written as this:

def greeting(name: str) -> str:
  return 'Hello, {}'.format(name)

As you can now see types, there's some sort of optional static type checking which will help you and your type checker to investigate your code.

for more explanation I suggest to take a look at the blog post on type hints in PyCharm blog.

Hope to give some extra input in solving this question (or part of it).

This will work for opening an Excel file from another. A line of code from Mr. Peter L., for the change, use the following:

Application.Workbooks.Open Filename:="C:\Book1withLinkToBook2.xlsx", UpdateLinks:=3

This is in MSDS. The effect is that it just updates everything (yes, everything) with no warning. This can also be checked if you record a macro.

In MSDS, it refers this to MS EXCEL 2010 and 2013. I'm thinking that MS EXCEL 2016 has this covered as well.

I have MS EXCEL 2013, and have a situation pretty much the same as this topic. So I have a file (call it A) with Workbook_Open event code that always get's stuck on the update links prompt. I have another file (call it B) connected to this one, and Pivot Tables force me to open the file A so that the data model can be loaded. Since I want to open the A file silently in the background, I just use the line that I wrote above, with a Windows("A.xlsx").visible = false, and, apart from a bigger loading time, I open the A file from the B file with no problems or warnings, and fully updated.

In my opinion a very easy and clean way could be:

go back to A

git checkout -f A

point master's head to the current state

git symbolic-ref HEAD refs/heads/master

save

git commit

I've eventually got this to work in the playground, having multiple characters I'm trying to remove from a string:

var new = otherstring.stringByTrimmingCharactersInSet(NSCharacterSet.init(charactersInString: "la t, \n \" ':"))
count(new) //result = 10
println(new) 
//yielding what I'm after just the numeric portion 40.7127837

You need to make sure the module is installed for all versions of python

You can check to see if a module is installed for python by running:

pip uninstall moduleName

If it is installed, it will ask you if you want to delete it or not. My issue was that it was installed for python, but not for python3. To check to see if a module is installed for python3, run:

python3 -m pip uninstall moduleName

After doing this, if you find that a module is not installed for one or both versions, use these two commands to install the module.

• pip install moduleName
• python3 -m pip install moduleName

You should be able to do the count on the purch variable:

purch.Count();

e.g.

var purch = from purchase in myBlaContext.purchases
select purchase;

purch.Count();

Extending Stuart Marks's answer, this can be done in a shorter way and without a concurrent map (if you don't need parallel streams):

public static <T> Predicate<T> distinctByKey(Function<? super T, ?> keyExtractor) {
    final Set<Object> seen = new HashSet<>();
    return t -> seen.add(keyExtractor.apply(t));
}

Then call:

persons.stream().filter(distinctByKey(p -> p.getName());

2019 Answer Late, but hope it helps somebody

This will make sure you won't get null on an empty textfield

• Textfield value is always 0
• When backspacing, you will end with 0
• When value is 0 and you start typing, 0 will be replaced with the actual number

// This will make sure that value never is null when textfield is empty

const minimum = 0;   

export default (props) => {
    const [count, changeCount] = useState(minimum);

    function validate(count) {
        return parseInt(count) | minimum
    }

    function handleChangeCount(count) {
        changeCount(validate(count))
    }

    return (
        <Form>
            <FormGroup>
                <TextInput
                    type="text"
                    value={validate(count)}
                    onChange={handleChangeCount}
                />
            </FormGroup>
            <ActionGroup>
                <Button type="submit">submit form</Button>
            </ActionGroup>
        </Form>
    );
};

If you want to filter your own commits:

git log --author="<$(git config user.email)>"

In my case, I needed to use RedirectToAction to solve the problem.

[HttpGet]
[ControleDeAcessoAuthorize("Report/ExportToPDF")]
public ActionResult ExportToPDF(int id, string month, string output)
{
    try
    {
        // Validate
        if (output != "PDF")
        {
            throw new Exception("Invalid output.");
        }
        else
        {
            ...// code to generate report in PDF format
        }
    }
    catch (Exception ex)
    {
        return RedirectToAction("Error");
    }
}

[ControleDeAcessoAuthorize("Report/Error")]
public ActionResult Error()
{
    return View();
}

I think Amarghosh answered correctly. If you want to Initialize an empty string(without knowing the size) the best way is:

//this will create an empty string without no memory allocation. 
char str[]="";// it is look like {0}

But if you want initialize a string with a fixed memory allocation you can do:

// this is better if you know your string size.    
char str[5]=""; // it is look like {0, 0, 0, 0, 0}

I've had this same issue. It turns out that for a web REFERENCE, you have to supply the URL as the first parameter to the constructor:

new WebService.WebServiceSoapClient("http://myservice.com/moo.aspx");

For a new style web SERVICE REFERENCE, you have to supply a name that refers to an endpoint entry in the configuration:

new WebService.WebServiceSoapClient("WebServiceEndpoint");

With a corresponding entry in Web.config or App.config:

<client>
      <endpoint address="http://myservice.com/moo.aspx"
        binding="basicHttpBinding" 
        bindingConfiguration="WebService"
        contract="WebService.WebServiceSoap"
        name="WebServiceEndpoint" />
    </client>
  </system.serviceModel>

Pretty damn hard to remove the tunnel vision on "it worked in an older program"...

Well actually github is much simpler than we think and absolutely it happens whenever we try to push even after we explicitly inserted some files in our git repository so, in order to fix the issue simply try..

: git pull

and then..

: git push

Note: if you accidently stuck in vim editor after pulling your repository than don't worry just close vim editor and try push :)

To the already proposed solutions I can add an option to configure an external Secrets Manager such as Vault.

1. Configure Vault Server vault server -dev (Only for DEV and not for PROD)
2. Write secrets vault write secret/somename key1=value1 key2=value2
3. Verify secrets vault read secret/somename

Add the following dependency to your SpringBoot project:

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-vault-config</artifactId>
</dependency>

Add Vault config properties:

spring.cloud.vault.host=localhost
spring.cloud.vault.port=8200
spring.cloud.vault.scheme=http
spring.cloud.vault.authentication=token
spring.cloud.vault.token=${VAULT_TOKEN}

Pass VAULT_TOKEN as an environment variable.

Refer to the documentation here.

There is a Spring Vault project which is also can be used for accessing, storing and revoking secrets.

Dependency:

<dependency>
    <groupId>org.springframework.vault</groupId>
    <artifactId>spring-vault-core</artifactId>
</dependency>

Configuring Vault Template:

@Configuration
class VaultConfiguration extends AbstractVaultConfiguration {

  @Override
  public VaultEndpoint vaultEndpoint() {
    return new VaultEndpoint();
  }

  @Override
  public ClientAuthentication clientAuthentication() {
    return new TokenAuthentication("…");
  }
}

Inject and use VaultTemplate:

public class Example {

  @Autowired
  private VaultOperations operations;

  public void writeSecrets(String userId, String password) {
      Map<String, String> data = new HashMap<String, String>();
      data.put("password", password);
      operations.write(userId, data);
  }

  public Person readSecrets(String userId) {
      VaultResponseSupport<Person> response = operations.read(userId, Person.class);
      return response.getBody();
  }
}

Use Vault PropertySource:

@VaultPropertySource(value = "aws/creds/s3",
  propertyNamePrefix = "aws."
  renewal = Renewal.RENEW)
public class Config {

}

Usage example:

public class S3Client {

  // inject the actual values
  @Value("${aws.access_key}")
  private String awsAccessKey;
  @Value("${aws.secret_key}")
  private String awsSecretKey;

  public InputStream getFileFromS3(String filenname) {
    // …
  }
}

For MariaDB, use modify column:

ALTER TABLE table_name MODIFY COLUMN column_name VARCHAR (500);

It will work.

I made an Objective-C version of Imagine Digitals swift answer above. I don't think I missed anything as it seems to work under preliminary testing, if you spot something let me know, and I'll update it

-(void) presentPopover
{
    YourViewController* popoverContent = [[YourViewController alloc] init]; //this will be a subclass of UIViewController
    UINavigationController* nav =  [[UINavigationController alloc] initWithRootViewController:popoverContent];
    nav.modalPresentationStyle = UIModalPresentationPopover;
    UIPopoverPresentationController* popover = nav.popoverPresentationController;
    popoverContent.preferredContentSize = CGSizeMake(500,600);
    popover.delegate = self;
    popover.sourceRect = CGRectMake(100,100,0,0); //I actually used popover.barButtonItem = self.myBarButton;

    [self presentViewController:nav animated:YES completion:nil];
}

If you know that you will only have that one querystring variable you can simply do:

var dest = location.search.replace(/^.*?\=/, '');

You can drop the database and then recreate it with the below:-

mysql> drop database [database name];
mysql> create database [database name];

My mistake was forgetting to add the .ThenInclude(s => s.SubChildEntities) onto the parent .Include(c => c.SubChildEntities) to the Controller action when attempting to call the SubChildEntities in the Razor view.

var <parent> = await _context.Parent
            .Include(c => c.<ChildEntities>)
            .ThenInclude(s => s.<SubChildEntities>)
            .SingleOrDefaultAsync(m => m.Id == id);

It should be noted that Visual Studio 2017 Community's IntelliSense doesn't pick up the SubChildEntities object in the lambda expression in the .ThenInclude(). It does successfully compile and execute though.

If you use location.hostname you will get your domain.com part. Then location.pathname will give you /path/folder. I would split location.pathname by / and reassemble the URL. But unless you need the querystring, you can just redirect to .. to go a directory above.

You can use the redirect URL to controller:

Class Ctrlr1 extends CI_Controller{
public void my_fct1(){
redirect('Ctrlr2 /my_fct2', 'refresh');
}
}


Class Ctrlr2 extends CI_Controller{
public void my_fct2(){
$this->load->view('view1');
}
}

FWIW I just hit this on a slightly different use case. I scoured and scoured my code looking for where I might've used a 'str' variable, but could not find it. I started to suspect that maybe one of the modules I imported was the culprit... but alas, it was a missing '%' character in a formatted print statement.

Here's an example:

x=5
y=6
print("x as a string is: %s.  y as a string is: %s" (str(x) , str(y)) )

This will result in the output:

   TypeError: 'str' object is not callable

The correction is:

x=5
y=6
print("x as a string is: %s.  y as a string is: %s" % (str(x) , str(y)) )

Resulting in our expected output:

x as a string is: 5. y as a string is: 6

Twitter bootstrap is meant to give a baseline functionality, and provides only basic javascript plugins that do something on screen. Any additional content or functionality, you'll have to do yourself.

<div class="btn-group">
  <button class="btn dropdown-toggle" data-toggle="dropdown">Action <span class="caret"></span></button>
  <ul class="dropdown-menu">
    <li><a href="#" id="action-1">Action</a></li>
    <li><a href="#" id="action-2">Another action</a></li>
    <li><a href="#" id="action-3">Something else here</a></li>
  </ul>
</div><!-- /btn-group -->

and then with jQuery

jQuery("#action-1").click(function(e){
//do something
e.preventDefault();
});

"toString()" is Very useful method which returns a string representation of an object. The "toString()" method returns a string reperentation an object.It is recommended that all subclasses override this method.

Declaration: java.lang.Object.toString()

Since, you have not mentioned which object you want to convert, so I am just using any object in sample code.

Integer integerObject = 5;
String convertedStringObject = integerObject .toString();
System.out.println(convertedStringObject );

You can find the complete code here. You can test the code here.

I'm trying to find a method to redirect my request from filter to login page

Don't

You just invoke

chain.doFilter(request, response);

from filter and the normal flow will go ahead.

I don't know how to redirect from servlet

You can use

response.sendRedirect(url);

to redirect from servlet

very simple one line solution:

<body onLoad="document.getElementById('myinputbox').focus();">

Try this:

<?php /* the php */ ?>
<?php 
    if ($_POST['submit']) {
        // must work
        echo $_POST['contact_list'];
    };
?>


 <?php /* and the html */ ?>

<!doctype html>
<html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>teszt</title>
    </head>
    <body>
        <form method="post" action="<?php echo $_SERVER['PHP_SELF'] ?>">
            <textarea id="contact_list" name="contact_list"></textarea>
            <input type="submit" name="submit" value="Send" id="submit"/>
        </form>
    </body>
</html>

You can use something like this

<div class="row">
     <div class="col-xs-2">
       <select id="info_type" class="form-control">
             <option>College</option>
             <option>Exam</option>
       </select>
     </div>

It's certainly possible to grab a screenshot using the .NET Framework. The simplest way is to create a new Bitmap object and draw into that using the Graphics.CopyFromScreen method.

Sample code:

using (Bitmap bmpScreenCapture = new Bitmap(Screen.PrimaryScreen.Bounds.Width, 
                                            Screen.PrimaryScreen.Bounds.Height))
using (Graphics g = Graphics.FromImage(bmpScreenCapture))
{
    g.CopyFromScreen(Screen.PrimaryScreen.Bounds.X,
                     Screen.PrimaryScreen.Bounds.Y,
                     0, 0,
                     bmpScreenCapture.Size,
                     CopyPixelOperation.SourceCopy);
}

Caveat: This method doesn't work properly for layered windows. Hans Passant's answer here explains the more complicated method required to get those in your screen shots.

Can't be done in pure HTML/JavaScript for security reasons.

Selecting a file for upload is the best you can do, and even then you won't get its full original path in modern browsers.

You may be able to put something together using Java or Flash (e.g. using SWFUpload as a basis), but it's a lot of work and brings additional compatibility issues.

Another thought would be opening an iframe showing the user's C: drive (or whatever) but even if that's possible nowadays (could be blocked for security reasons, haven't tried in a long time) it will be impossible for your web site to communicate with the iframe (again for security reasons).

What do you need this for?

In my case the command below did the job

pip3 install pyserial

You have to enable access first: Configuring Manager Application Access

Input: 192.168.0.1/25

The mask is this part: /25

To find the network address do the following:

• Subtract the mask from the ip length (32 - mask) = 32 - 25 = 7 and take those bits from the right

• In the given ip address I.e: 192.168.0.1 in binary is: 11111111 11111111 00000000 00000001 Now, taking 7 bits from right '0' 1111111 11111111 00000000 00000000 Which in decimal is: 192.168.0.0 (this is the network address)

To find first valid/usable ip address add +1 to network address I.e: 192.168.0.1

To find the last/broadcast address the procedure is same as that of finding network address but here you have to make (32-mask) bits from right to '1'

I.e: 11111111 11111111 00000000 01111111 Which in decimal is 192.168.0.127

To find the last valid/usable ip address subtract 1 from the broadcast address I.e: 192.168.0.126

You can assign function to all checkboxes then ask for confirmation inside of it. If they choose yes, checkbox is allowed to be changed if no it remains unchanged.

In my case I am also using ASP .Net checkbox inside a repeater (or grid) with Autopostback="True" attribute, so on server side I need to compare the value submitted vs what's currently in db in order to know what confirmation value they chose and update db only if it was "yes".

$(document).ready(function () {
    $('input[type=checkbox]').click(function(){                
        var areYouSure = confirm('Are you sure you want make this change?');
        if (areYouSure) {
            $(this).prop('checked', this.checked);
        } else {
            $(this).prop('checked', !this.checked);
        }
    });
}); 


<asp:CheckBox ID="chk" AutoPostBack="true" onCheckedChanged="chk_SelectedIndexChanged" runat="server" Checked='<%#Eval("FinancialAid") %>' />

protected void chk_SelectedIndexChanged(Object sender, EventArgs e)
{
    using (myDataContext db = new myDataDataContext())
    {
        CheckBox chk = (CheckBox)sender;
        RepeaterItem row = (RepeaterItem) chk.NamingContainer;            
        var studentID = ((Label) row.FindControl("lblID")).Text;
        var z = (from b in db.StudentApplicants
        where b.StudentID == studentID
        select b).FirstOrDefault();                
        if(chk != null && chk.Checked != z.FinancialAid){
            z.FinancialAid = chk.Checked;                
            z.ModifiedDate = DateTime.Now;
            db.SubmitChanges();
            BindGrid();
        }
        gvData.DataBind();
    }
}

If you are trying to track down which line caused an error, if you right-click in the Python shell where the line error is displayed it will come up with a "Go to file/line" which takes you directly to the line in question.

As you want your answer in decimal number so you dont need to typecast your answer variable to str in printC() function.

and then use printf-style String Formatting

My two cents :)

private:

class -> a top level class cannot be private. inner classes can be private which are accessible from same class.

instance variable -> accessible only in the class. Cannot access outside the class.

package-private:

class -> a top level class can be package-private. It can only be accessible from same package. Not from sub package, not from outside package.

instance variable -> accessible from same package. Not from sub package, not from outside package.

protected:

class -> a top level class cannot be protected.

instance variable -> Only accessible in same package or subpackage. Can only be access outside the package while extending class.

public:

class -> accessible from package/subpackage/another package

instance variable -> accessible from package/subpackage/another package

Rewrite @Juned Ahsan solution via stream in one line (headers are treated the same way):

public static String printRequest(HttpServletRequest req) {
    String params = StreamSupport.stream(
            ((Iterable<String>) () -> req.getParameterNames().asIterator()).spliterator(), false)
            .map(pName -> pName + '=' + req.getParameter(pName))
            .collect(Collectors.joining("&"));
    return req.getRequestURI() + '?' + params;
}

I think this is what you are looking for? If you are looking to add a blur effect to a div element, you can do this directly through CSS Filters-- See fiddle: http://jsfiddle.net/ayhj9vb0/

 div {
  -webkit-filter: blur(5px);
  -moz-filter: blur(5px);
  -o-filter: blur(5px);
  -ms-filter: blur(5px);
  filter: blur(5px);
  width: 100px;
  height: 100px;
  background-color: #ccc;

}

Why not ?

Just modify your Main-Class to receive arguments and act upon the argument.

public class wiki2txt {

    public static void main(String[] args) {

          String fileName = args[0];

          // Use FileInputStream, BufferedReader etc here.

    }
}

Specify the full path in the commandline.

java -jar wiki2txt /home/bla/enwiki-....xml

I agree with aberrant80.

For enums, I test them only when they actually have methods in them. If it's a pure value-only enum like your example, I'd say don't bother.

But since you're keen on testing it, going with your second option is much better than the first. The problem with the first is that if you use an IDE, any renaming on the enums would also rename the ones in your test class.

I would expand on it by adding that unit testings an Enum can be very useful. If you work in a large code base, build time starts to mount up and a unit test can be a faster way to verify functionality (tests only build their dependencies). Another really big advantage is that other developers cannot change the functionality of your code unintentionally (a huge problem with very large teams).

And with all Test Driven Development, tests around an Enums Methods reduce the number of bugs in your code base.

Simple Example

public enum Multiplier {
    DOUBLE(2.0),
    TRIPLE(3.0);

    private final double multiplier;

    Multiplier(double multiplier) {
        this.multiplier = multiplier;
    }

    Double applyMultiplier(Double value) {
        return multiplier * value;
    }

}

public class MultiplierTest {

    @Test
    public void should() {
        assertThat(Multiplier.DOUBLE.applyMultiplier(1.0), is(2.0));
        assertThat(Multiplier.TRIPLE.applyMultiplier(1.0), is(3.0));
    }
}

I ran across the answers here, and was attracted by the fact that there seems to be someone poking around, believing that an Activity context is required. This is not the case. However, it is a requirement that a Toast is posted from the main event or UI Thread. So, getting this to work outside of an activity context is a little bit tricky. Here is an example that would work inside of a system service, or any potential class that ultimately inherits from Context.

public class MyService extends AccessibilityService {

    public void postToastMessage(final String message) {
        Handler handler = new Handler(Looper.getMainLooper());

        handler.post(new Runnable() {

            @Override
            public void run() {
                Toast.makeText(getApplicationContext(), message, Toast.LENGTH_LONG).show();
            }
        });
    }
}

Note that we do not need access to an instance of Activity for this to work. Please stop suggesting this is the case! If Activity were required, the method signature wouldn't call for a Context.

On Windows 8 Pro:

%systemroot%\inetsrv\config

On Windows 7 and 8.1 and 10

%systemroot%\System32\inetsrv\config 

(Where %systemroot% is usually C:\Windows)

Navigate to the appropriate location above in Windows Explorer. You will be blocked access with a popup which says:

"You don't have access to this folder - Click continue to permanently get access to this folder"

Click 'continue' for this folder, and with the Export folder underneath. I changed the shortcut back to "Run as me" (a member of the domain and local administrators ) and was able to open and deploy the solution.

You might want to do it like this:

DateTime? lastPostDate =  (DateTime?)(reader.IsDbNull(3) ? null : reader[3]); 

The problem you are having is that the ternary operator wants a viable cast between the left and right sides. And null can't be cast to DateTime.

Note the above works because both sides of the ternary are object's. The object is explicitly cast to DateTime? which works: as long as reader[3] is in fact a date.

Try This,

public View getView(final int position, View convertView,ViewGroup parent) 
{
   if(convertView == null)
   {
        LayoutInflater inflater = getLayoutInflater();
        convertView  = (LinearLayout)inflater.inflate(R.layout.YOUR_LAYOUT, null);
   }

   Button Button1= (Button)  convertView  .findViewById(R.id.BUTTON1_ID);

   Button1.setOnClickListener(new OnClickListener() 
   { 
       @Override
       public void onClick(View v) 
       {
           // Your code that you want to execute on this button click
       }

   });


   return convertView ;
}

It may help you....

After a lot of searching the web and trying to find the most suitable form for routing map if have found the following

config.Routes.MapHttpRoute("DefaultApiWithId", "Api/{controller}/{id}", new { id =RouteParameter.Optional }, new { id = @"\d+" });
config.Routes.MapHttpRoute("DefaultApiWithAction", "Api/{controller}/{action}");

These mapping applying to both action name mapping and basic http convention (GET,POST,PUT,DELETE)

I had such problem. In my case problem was in data - my column 'information' contained 1 unique value and it caused error

UPDATE: to correct work 'pivot' pairs (id_user,information) cannot have duplicates

It works:

df2 = pd.DataFrame({'id_user':[1,2,3,4,4,5,5], 
'information':['phon','phon','phone','phone1','phone','phone1','phone'], 
'value': [1, '01.01.00', '01.02.00', 2, '01.03.00', 3, '01.04.00']})
df2.pivot(index='id_user', columns='information', values='value')

it doesn't work:

df2 = pd.DataFrame({'id_user':[1,2,3,4,4,5,5], 
'information':['phone','phone','phone','phone','phone','phone','phone'], 
'value': [1, '01.01.00', '01.02.00', 2, '01.03.00', 3, '01.04.00']})
df2.pivot(index='id_user', columns='information', values='value')

A couple of comments that IMO are important:

• input elements not not emitting 'change' event until USER action ENTER or blur await IS the correct behavior.

• The event you want to use is "input" ("oninput"). Here is well demonstrated the different between the two: https://javascript.info/events-change-input

• The two events signal two different user gestures/moments ("input" event means user is writing or navigating a select list options, but still didn't confirm the change. "change" means user did changed the value (with an enter or blur our)

• Listening for key events like many here recommended is a bad practice in this case. (like people modifying the default behavior of ENTER on inputs)...

• jQuery has nothing to do with this. This is all in HTML standard.

• If you have problems understanding WHY this is the correct behavior, perhaps is helpful, as experiment, use your text editor or browser without a mouse/pad, just a keyboard.

My two cents.
