I have also found that you can use verbose=2 to make keras print out the Losses:

history = model.fit(X, Y, validation_split=0.33, nb_epoch=150, batch_size=10, verbose=2)

And that would print nice lines like this:

Epoch 1/1
 - 5s - loss: 0.6046 - acc: 0.9999 - val_loss: 0.4403 - val_acc: 0.9999

According to their documentation:

verbose: 0, 1, or 2. Verbosity mode. 0 = silent, 1 = progress bar, 2 = one line per epoch.

The acepted Answer is very detailed and correct in most of the cases.

I just want to add that i was getting an error while attempting to load a JSON text file encoded with UTF8, i had a well formatted JSON but the 'json_decode' always returned me with NULL, it was due the BOM mark.

To solve it, i made this PHP function:

function load_utf8_file($filePath)
{
    $response = null;
    try
    {
        if (file_exists($filePath)) {
            $text = file_get_contents($filePath);
            $response = preg_replace("/^\xEF\xBB\xBF/", '', $text);          
        }     
    } catch (Exception $e) {
      echo 'ERROR: ',  $e->getMessage(), "\n";
   }
   finally{  }
   return $response;
}

Then i use it like this to load a JSON file and get a value from it:

$str = load_utf8_file('appconfig.json'); 
$json = json_decode($str, true); 
//print_r($json);
echo $json['prod']['deploy']['hostname'];

You can easily use xml (from the Python standard library) to convert to a pandas.DataFrame. Here's what I would do (when reading from a file replace xml_data with the name of your file or file object):

import pandas as pd
import xml.etree.ElementTree as ET
import io

def iter_docs(author):
    author_attr = author.attrib
    for doc in author.iter('document'):
        doc_dict = author_attr.copy()
        doc_dict.update(doc.attrib)
        doc_dict['data'] = doc.text
        yield doc_dict

xml_data = io.StringIO(u'''\

etree = ET.parse(xml_data) #create an ElementTree object 
doc_df = pd.DataFrame(list(iter_docs(etree.getroot())))

If there are multiple authors in your original document or the root of your XML is not an author, then I would add the following generator:

def iter_author(etree):
    for author in etree.iter('author'):
        for row in iter_docs(author):
            yield row

and change doc_df = pd.DataFrame(list(iter_docs(etree.getroot()))) to doc_df = pd.DataFrame(list(iter_author(etree)))

Have a look at the ElementTree tutorial provided in the xml library documentation.

For people out there asking how to setup proxy server in chrome which needs authentication should follow these steps.

1. Create a proxy.py file in your project, use this code and call proxy_chrome from
   proxy.py everytime you need it. You need to pass parameters like proxy server, port and username password for authentication.

<?php
$string = 'This is your string';

if( strlen( $string ) > 50 ) {
   $string = substr( $string, 0, 50 ) . '...';
}

That's it.

First convert the numeric value then add the 'S':

 select convert(varchar(10),StandardCost) +'S'
 from DimProduct where ProductKey = 212

The pure javascript solution is better, but a jQuery way would be to use the jQuery grep and/or map methods. Probably not much better than using $.each

jQuery.grep(TestObj, function(obj) {
    return obj.id === "A";
});

or

jQuery.map(TestObj, function(obj) {
    if(obj.id === "A")
         return obj; // or return obj.name, whatever.
});

Returns an array of the matching objects, or of the looked-up values in the case of map. Might be able to do what you want simply using those.

But in this example you'd have to do some recursion, because the data isn't a flat array, and we're accepting arbitrary structures, keys, and values, just like the pure javascript solutions do.

function getObjects(obj, key, val) {
    var retv = [];

    if(jQuery.isPlainObject(obj))
    {
        if(obj[key] === val) // may want to add obj.hasOwnProperty(key) here.
            retv.push(obj);

        var objects = jQuery.grep(obj, function(elem) {
            return (jQuery.isArray(elem) || jQuery.isPlainObject(elem));
        });

        retv.concat(jQuery.map(objects, function(elem){
            return getObjects(elem, key, val);
        }));
    }

    return retv;
}

Essentially the same as Box9's answer, but using the jQuery utility functions where useful.

One way, using regular expressions:

>>> s = "how much for the maple syrup? $20.99? That's ridiculous!!!"
>>> re.sub(r'[^\w]', ' ', s)
'how much for the maple syrup   20 99  That s ridiculous   '

• \w will match alphanumeric characters and underscores

• [^\w] will match anything that's not alphanumeric or underscore

This is the modernization of m.kocikowski answer which removes whitespaces:

@implementation NSString (StripXMLTags)

- (NSString *)stripXMLTags
{
    NSRange r;
    NSString *s = [self copy];
    while ((r = [s rangeOfString:@"<[^>]+>\\s*" options:NSRegularExpressionSearch]).location != NSNotFound)
        s = [s stringByReplacingCharactersInRange:r withString:@""];
    return s;
}

@end

Loop through the second array each time you iterate over an element in the first array, then check for matches.

var array1 = ["cat", "sum", "fun", "run"],
    array2 = ["bat", "cat", "dog", "sun", "hut", "gut"];

function getMatch(a, b) {
    var matches = [];

    for ( var i = 0; i < a.length; i++ ) {
        for ( var e = 0; e < b.length; e++ ) {
            if ( a[i] === b[e] ) matches.push( a[i] );
        }
    }
    return matches;
}

getMatch(array1, array2); // ["cat"]

They're just trawling lists of web sites, and recording the resulting IP addresses in a database.

All you're seeing is the reverse mapping of that list. It's not guaranteed to be a full list (indeed more often than not it won't be) because it's impossible to learn every possible web site address.

std::map takes up to four template type arguments, the third one being a comparator. E.g.:

struct cmpByStringLength {
    bool operator()(const std::string& a, const std::string& b) const {
        return a.length() < b.length();
    }
};

// ...
std::map<std::string, std::string, cmpByStringLength> myMap;

Alternatively you could also pass a comparator to maps constructor.

Note however that when comparing by length you can only have one string of each length in the map as a key.

I am researching the same thing and stumbled upon identityserver which implements OAuth and OpenID on top of ASP.NET. It integrates with ASP.NET identity and Membership Reboot with persistence support for Entity Framework.

So, to answer your question, check out their detailed document on how to setup an OAuth and OpenID server.

What you mean to do is:

jQuery(this).prev("li").attr("id", "newID");

That will set the ID to the new ID

This is really easy: Example

//my object
var sendData = {field1:value1, field2:value2};

//add element
sendData['field3'] = value3;

The best solution is to add to your apache .htaccess file the following line after RewriteEngine On

RewriteRule ^sitemap\.xml$ sitemap.php [L]

and then simply having a file sitemap.php in your root folder that would be normally accessible via http://www.yoursite.com/sitemap.xml, the default URL where all search engines will firstly search.

The file sitemap.php shall start with

<?php
//Saturday, 11 January 2020 @kevin

header('Content-type: text/xml');
echo '<?xml version="1.0" encoding="UTF-8"?>';
?>
<urlset
      xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9
            http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd">

  <lastmod>2020-01-08T13:06:14+00:00</lastmod>
  <priority>1.00</priority>
</url>


</urlset>

it works :)

Try this.

@Query("Select c from Registration c where c.place like '%'||:place||'%'")

Yes of course, function are objects and can be passed, but of course you must declare it:

function firstFunction(){
    //some code
    var callbackfunction = function(data){
       //do something with the data returned from the ajax request
     }
    //a callback function is written for $.post() to execute
    secondFunction("var1","var2",callbackfunction);
}

an interesting thing is that your callback function has also access to every variable you might have declared inside firstFunction() (variables in javascript have local scope).

Weston Ruther built a similar thing using the WebKit proposal for css transitions:

This implementation might be useful for you.

If using RCurl you get an SSL error on the GetURL() function then set these options before GetURL(). This will set the CurlSSL settings globally.

The extended code:

install.packages("RCurl")
library(RCurl)
options(RCurlOptions = list(cainfo = system.file("CurlSSL", "cacert.pem", package = "RCurl")))   
URL <- "https://d396qusza40orc.cloudfront.net/getdata%2Fdata%2Fss06hid.csv"
x <- getURL(URL)

Worked for me on Windows 7 64-bit using R3.1.0!

void show() throws Exception
{
    throw new Exception("my.own.Exception");
}

As there is checked exception in show() method , which is not being handled in that method so we use throws keyword for propagating the Exception.

void show2() throws Exception //Why throws is necessary here ?
{
show();
}

Since you are using the show() method in show2() method and you have propagated the exception atleast you should be handling here. If you are not handling the Exception here , then you are using throws keyword. So that is the reason for using throws keyword at the method signature.

In your entity class add @JsonInclude(JsonInclude.Include.NON_NULL) annotation to resolve the problem

it will look like

@Entity
@JsonInclude(JsonInclude.Include.NON_NULL)

In jQuery, you can do alert($("#theid").css("width")).

-- if you haven't taken a look at jQuery, I highly recommend it; it makes many simple javascript tasks effortless.

Update

for the record, this post is 5 years old. The web has developed, moved on, etc. There are ways to do this with Plain Old Javascript, which is better.

I also faced the same problem a long time ago.

Here is the Solution

In Eclipse Click on "Windows"-->"Preferences"---->"Java"---> "Installed JREs"---->Select the JDK, click on "Edit".

Check your JDK path, is it according to your path in environmental variables defined in system. if not then change it to "path" defined directory.

The algorithm to go from infix to prefix expressions is:

-reverse input

TOS = top of stack
If next symbol is:
 - an operand -> output it
 - an operator ->
        while TOS is an operator of higher priority -> pop and output TOS
        push symbol
 - a closing parenthesis -> push it
 - an opening parenthesis -> pop and output TOS until TOS is matching
        parenthesis, then pop and discard TOS.

-reverse output

So your example goes something like (x PUSH, o POP):

2*3/(2-1)+5*(4-1)
)1-4(*5+)1-2(/3*2

Next
Symbol  Stack           Output

DEMO

http://jsfiddle.net/ssuryar/wcmHu/429/

you can do it in such way:

sqlConnection.Open();

string sqlQuery = "INSERT INTO [dbo].[Customer]([FirstName],[LastName],[Address],[City]) VALUES (@FirstName,@LastName,@Address,@City)";
sqlConnection.Execute(sqlQuery,
    new
    {
        customerEntity.FirstName,
        customerEntity.LastName,
        customerEntity.Address,
        customerEntity.City
    });

sqlConnection.Close();

I used:

echo exec('whoami');

to find out who is running the script (say username), and then gave the user permissions to the entire application directory, like:

sudo chown -R :username /var/www/html/myapp

Detecting porn images is still a definite AI task which is very much theoretical yet.

Harvest collective power and human intelligence by adding a button/link "Report spam/abuse". Or employ several moderators to do this job.

P.S. Really surprised how many people ask questions assuming software and algorithms are all-mighty without even thinking whether what they want could be done. Are they representatives of that new breed of programmers who have no understanding of hardware, low-level programming and all that "magic behind"?

P.S. #2. I also remember that periodically it happens that some situation when people themselves cannot decide whether a picture is porn or art is taken to the court. Even after the court rules, chances are half of the people will consider the decision wrong. The last stupid situation of the kind was quite recently when a Wikipedia page got banned in UK because of a CD cover image that features some nakedness.

You can run OpenSSH on Cygwin, and even install it as a Windows service.

I once used it this way to easily add backups of a Unix system - it would rsync a bunch of files onto the Windows server, and the Windows server had full tape backups.

A lot of answers only explain how to do the search.

To view the results look for a search tab (normally docked at the bottom of the screen):

Validate phone number + return formatted data

function validTel(str){_x000D_
  str = str.replace(/[^0-9]/g, '');_x000D_
  var l = str.length;_x000D_
  if(l<10) return ['error', 'Tel number length < 10'];_x000D_
  _x000D_
  var tel = '', num = str.substr(-7),_x000D_
      code = str.substr(-10, 3),_x000D_
      coCode = '';_x000D_
  if(l>10) {_x000D_
    coCode = '+' + str.substr(0, (l-10) );_x000D_
  }_x000D_
  tel = coCode +' ('+ code +') '+ num;_x000D_
  _x000D_
  return ['succes', tel];_x000D_
}_x000D_
_x000D_
console.log(validTel('+1 [223] 123.45.67'));

Install an interval:

Here is one-line list-comprehension variant of Pat's answer (which also includes that you wanted to glob in a specific project directory):

import os, glob
exts = ['*.txt', '*.mdown', '*.markdown']
files = [f for ext in exts for f in glob.glob(os.path.join(project_dir, ext))]

You loop over the extensions (for ext in exts), and then for each extension you take each file matching the glob pattern (for f in glob.glob(os.path.join(project_dir, ext)).

This solution is short, and without any unnecessary for-loops, nested list-comprehensions, or functions to clutter the code. Just pure, expressive, pythonic Zen.

This solution allows you to have a custom list of exts that can be changed without having to update your code. (This is always a good practice!)

The list-comprehension is the same used in Laurent's solution (which I've voted for). But I would argue that it is usually unnecessary to factor out a single line to a separate function, which is why I'm providing this as an alternative solution.

Bonus:

If you need to search not just a single directory, but also all sub-directories, you can pass recursive=True and use the multi-directory glob symbol ** ¹:

files = [f for ext in exts 
         for f in glob.glob(os.path.join(project_dir, '**', ext), recursive=True)]

This will invoke glob.glob('<project_dir>/**/*.txt', recursive=True) and so on for each extension.

¹ Technically, the ** glob symbol simply matches one or more characters including forward-slash / (unlike the singular * glob symbol). In practice, you just need to remember that as long as you surround ** with forward slashes (path separators), it matches zero or more directories.

add_header works as well with proxy_pass as without. I just today set up a configuration where I've used exactly that directive. I have to admit though that I've struggled as well setting this up without exactly recalling the reason, though.

Right now I have a working configuration and it contains the following (among others):

server {
    server_name  .myserver.com
    location / {
        proxy_pass  http://mybackend;
        add_header  X-Upstream  $upstream_addr;
    }
}

Before nginx 1.7.5 add_header worked only on successful responses, in contrast to the HttpHeadersMoreModule mentioned by Sebastian Goodman in his answer.

Since nginx 1.7.5 you can use the keyword always to include custom headers even in error responses. For example:

add_header X-Upstream $upstream_addr always;

Limitation: You cannot override the server header value using add_header.

I had the same issue and came up with the following that uses underscore's _.filter method. Once I discovered that removeClass takes a function and provides you with a list of classnames, it was easy to turn that into an array and filter out the classname to return back to the removeClass method.

// Wildcard removeClass on 'color-*'
$('[class^="color-"]').removeClass (function (index, classes) {
  var
    classesArray = classes.split(' '),
    removeClass = _.filter(classesArray, function(className){ return className.indexOf('color-') === 0; }).toString();

  return removeClass;
});

'Millis since unix epoch' represents an instant, so you should use the Instant class:

private long toEpochMilli(LocalDateTime localDateTime)
{
  return localDateTime.atZone(ZoneId.systemDefault())
    .toInstant().toEpochMilli();
}

Are you meaning?

data2 <- data1[good,]

With

data1[good]

you're selecting columns in a wrong way (using a logical vector of complete rows).

Consider that parameter pollutant is not used; is it a column name that you want to extract? if so it should be something like

data2 <- data1[good, pollutant]

Furthermore consider that you have to rbind the data.frames inside the for loop, otherwise you get only the last data.frame (its completed.cases)

And last but not least, i'd prefer generating filenames eg with

id <- 1:322
paste0( directory, "/", gsub(" ", "0", sprintf("%3d",id)), ".csv")

A little modified chunk of ?sprintf

The string fmt (in our case "%3d") contains normal characters, which are passed through to the output string, and also conversion specifications which operate on the arguments provided through .... The allowed conversion specifications start with a % and end with one of the letters in the set aAdifeEgGosxX%. These letters denote the following types:

• d: integer

Eg a more general example

    sprintf("I am %10d years old", 25)
[1] "I am         25 years old"
          ^^^^^^^^^^
          |        |
          1       10

Here is how I resolved it.

It is not the most secure way however it solved my problem as security was not an issue on internal servers.

Create a new file say password.txt and store the password for the server where the file will be pasted. Save this to a location on the host server.

scp -W location/password.txt copy_file_location paste_file_location

Cheers!

Assertions are generally used primarily as a means of checking the program's expected behavior. It should lead to a crash in most cases, since the programmer's assumptions about the state of the program are false. This is where the debugging aspect of assertions come in. They create a checkpoint that we simply can't ignore if we would like to have correct behavior.

In your case it does data validation on the incoming parameters, though it does not prevent clients from misusing the function in the future. Especially if they are not, (and should not) be included in release builds.

Here's an answer, based on (and I think an improvement on) Tester101's answer, expressed as a subroutine, with the CopyFile line once instead of three times, and prepared to handle changing the file name as the copy is made (no hard-coded destination directory). I also found I had to delete the target file before copying to get this to work, but that might be a Windows 7 thing. The WScript.Echo statements are because I didn't have a debugger and can of course be removed if desired.

Sub CopyFile(SourceFile, DestinationFile)

    Set fso = CreateObject("Scripting.FileSystemObject")

    'Check to see if the file already exists in the destination folder
    Dim wasReadOnly
    wasReadOnly = False
    If fso.FileExists(DestinationFile) Then
        'Check to see if the file is read-only
        If fso.GetFile(DestinationFile).Attributes And 1 Then 
            'The file exists and is read-only.
            WScript.Echo "Removing the read-only attribute"
            'Remove the read-only attribute
            fso.GetFile(DestinationFile).Attributes = fso.GetFile(DestinationFile).Attributes - 1
            wasReadOnly = True
        End If

        WScript.Echo "Deleting the file"
        fso.DeleteFile DestinationFile, True
    End If

    'Copy the file
    WScript.Echo "Copying " & SourceFile & " to " & DestinationFile
    fso.CopyFile SourceFile, DestinationFile, True

    If wasReadOnly Then
        'Reapply the read-only attribute
        fso.GetFile(DestinationFile).Attributes = fso.GetFile(DestinationFile).Attributes + 1
    End If

    Set fso = Nothing

                tiff.Dispose();
                bitmap.Dispose();
                File.Delete(filename);

            }


        }

This should do it in the correct way:

mainFrame.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
mainFrame.addWindowListener(new WindowListener() {

@Override
public void windowClosing(WindowEvent e) {
    if (doQuestion("Really want to exit?")) {
      mainFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      mainFrame.dispose();
    }
}

It's because Arrays.asList(array) return List<int[]>. array argument is treated as one value you want to wrap (you get list of arrays of ints), not as vararg.

Note that it does work with object types (not primitives):

public boolean contains(final String[] array, final String key) {
    return Arrays.asList(array).contains(key);
}

or even:

public <T>  boolean contains(final T[] array, final T key) {
    return Arrays.asList(array).contains(key);
}

But you cannot have List<int> and autoboxing is not working here.

To me it seems like the best solution is to use a directive; there's no need for the controller to know that the view is being updated.

Javascript:

var app = angular.module('app', ['directives']);

angular.module('directives', []).directive('toggleClass', function () {
    var directiveDefinitionObject = {
        restrict: 'A',
        template: '<span ng-click="localFunction()" ng-class="selected"  ng-transclude></span>',
        replace: true,
        scope: {
            model: '='
        },
        transclude: true,
        link: function (scope, element, attrs) {
            scope.localFunction = function () {
                scope.model.value = scope.$id;
            };
            scope.$watch('model.value', function () {
                // Is this set to my scope?
                if (scope.model.value === scope.$id) {
                    scope.selected = "active";
                } else {
                    // nope
                    scope.selected = '';
                }
            });
        }
    };
    return directiveDefinitionObject;
});

HTML:

<div ng-app="app" ng-init="model = { value: 'dsf'}"> <span>Click a span... then click another</span>

<br/>
<br/>
<span toggle-class model="model">span1</span>

<br/><span toggle-class model="model">span2</span>

<br/><span toggle-class model="model">span3</span>

CSS:

.active {
     color:red;
 }

I have a fiddle that demonstrates. The idea is when a directive is clicked, a function is called on the directive that sets a variable to the current scope id. Then each directive also watches the same value. If the scope ID's match, then the current element is set to be active using ng-class.

The reason to use directives, is that you no longer are dependent on a controller. In fact I don't have a controller at all (I do define a variable in the view named "model"). You can then reuse this directive anywhere in your project, not just on one controller.

Once you have a JArray you can treat it just like any other Enumerable object, and using linq you can access them, check them, verify them, and select them.

var str = @"[1, 2, 3]";
var jArray = JArray.Parse(str);
Console.WriteLine(String.Join("-", jArray.Where(i => (int)i > 1).Select(i => i.ToString())));

Are we talking about standard java.io.FileReader? Won't work, but it's not hard without it.

/src/main/resources maven directory contents are placed in the root of your CLASSPATH, so you can simply retrieve it using:

InputStream is = getClass().getResourceAsStream("/storedProcedures.sql");

If the result is not null (resource not found), feel free to wrap it in a reader:

Reader reader = new InputStreamReader(is);

This following works better if you need to scroll to an arbitrary item in the list (rather than always to the bottom):

function scrollIntoView(element, container) {
  var containerTop = $(container).scrollTop(); 
  var containerBottom = containerTop + $(container).height(); 
  var elemTop = element.offsetTop;
  var elemBottom = elemTop + $(element).height(); 
  if (elemTop < containerTop) {
    $(container).scrollTop(elemTop);
  } else if (elemBottom > containerBottom) {
    $(container).scrollTop(elemBottom - $(container).height());
  }
}

The accepted answer did not work for me. The Date returned is always the local Date and not the Date for the original Time Zone. I live in UTC+2.

//This did not work for me
Date.from(java.time.ZonedDateTime.now().toInstant()); 

I have come up with two alternative ways to get the correct Date from a ZonedDateTime.

Say you have this ZonedDateTime for Hawaii

LocalDateTime ldt = LocalDateTime.now();
ZonedDateTime zdt = ldt.atZone(ZoneId.of("US/Hawaii"); // UTC-10

or for UTC as asked originally

Instant zulu = Instant.now(); // GMT, UTC+0
ZonedDateTime zdt = zulu.atZone(ZoneId.of("UTC"));

Alternative 1

We can use java.sql.Timestamp. It is simple but it will probably also make a dent in your programming integrity

Date date1 = Timestamp.valueOf(zdt.toLocalDateTime());

Alternative 2

We create the Date from millis (answered here earlier). Note that local ZoneOffset is a must.

ZoneOffset localOffset = ZoneOffset.systemDefault().getRules().getOffset(LocalDateTime.now());
long zonedMillis = 1000L * zdt.toLocalDateTime().toEpochSecond(localOffset) + zdt.toLocalDateTime().getNano() / 1000000L;
Date date2 = new Date(zonedMillis);

Use [^\p{L}\p{Nd}]+ - this matches all (Unicode) characters that are neither letters nor (decimal) digits.

In Java:

String resultString = subjectString.replaceAll("[^\\p{L}\\p{Nd}]+", "");

Edit:

I changed \p{N} to \p{Nd} because the former also matches some number symbols like ¼; the latter doesn't. See it on regex101.com.

You can use the row_number() function for this.

INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
    SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
            row_number() over (order by (select NULL))
    FROM PM_Ingrediants 
    WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
                             )

If you want to start with the maximum already in the table then do:

INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
    SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
           coalesce(const.maxs, 0) + row_number() over (order by (select NULL))
    FROM PM_Ingrediants cross join
         (select max(sequence) as maxs from PM_Ingrediants_Arrangement_Temp) const
    WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
                             )

Finally, you can just make the sequence column an auto-incrementing identity column. This saves the need to increment it each time:

create table PM_Ingrediants_Arrangement_Temp ( . . .
    sequence int identity(1, 1) -- and might consider making this a primary key too
    . . .
)

use this in your view

<EditText 
    ....
    ....
    android:imeOptions="actionDone" 
    android:id="@+id/edtName"
    />

I did a search, which requires you to input a certain value, then it will look for a value from the list which contains your input:

my_list = ['abc-123',
        'def-456',
        'ghi-789',
        'abc-456'
        ]

imp = raw_input('Search item: ')

for items in my_list:
    val = items
    if any(imp in val for items in my_list):
        print(items)

Try searching for 'abc'.

A less known difference is that in operating systems with optimistic memory allocation, like Linux, the pointer returned by malloc isn't backed by real memory until the program actually touches it.

calloc does indeed touch the memory (it writes zeroes on it) and thus you'll be sure the OS is backing the allocation with actual RAM (or swap). This is also why it is slower than malloc (not only does it have to zero it, the OS must also find a suitable memory area by possibly swapping out other processes)

See for instance this SO question for further discussion about the behavior of malloc

You can either use -FLT_MAX (or -DBL_MAX) for the maximum magnitude negative number and FLT_MAX (or DBL_MAX) for positive. This gives you the range of possible float (or double) values.

You probably don't want to use FLT_MIN; it corresponds to the smallest magnitude positive number that can be represented with a float, not the most negative value representable with a float.

FLT_MIN and FLT_MAX correspond to std::numeric_limits<float>::min() and std::numeric_limits<float>::max().

Super simple example. Regular expressions are extremely easy to find online.

This is strictly not speaking using jQuery, but I have found this method easier than using jQuery. There are probably endless methods of achieving this and many clever ones here, but not all have worked for me. However the following method has always worked and I am passing it one in case it helps someone else.

Three javascript libraries are required, createCookie, readCookie and eraseCookie. These libraries are not mine but I began using them about 5 years ago and don't know their origin.

createCookie = function(name, value, days) {
if (days) {
    var date = new Date();
    date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
    var expires = "; expires=" + date.toGMTString();
}
else var expires = "";

document.cookie = name + "=" + value + expires + "; path=/";
}

readCookie = function (name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for (var i = 0; i < ca.length; i++) {
    var c = ca[i];
    while (c.charAt(0) == ' ') c = c.substring(1, c.length);
    if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
}
return null;
}
eraseCookie = function (name) {
   createCookie(name, "", -1);
}

To call them you need to create a small PHP function, normally as part of your support library, as follows:

<?php
 function createjavaScriptCookie($sessionVarible) {
 $s =  "<script>";
 $s = $s.'createCookie('. '"'. $sessionVarible                 
 .'",'.'"'.$_SESSION[$sessionVarible].'"'. ',"1"'.')';
 $s = $s."</script>";
 echo $s;
}
?>

So to use all you now have to include within your index.php file is

$_SESSION["video_dir"] = "/video_dir/";
createjavaScriptCookie("video_dir");

Now in your javascript library.js you can recover the cookie with the following code:

var videoPath = readCookie("video_dir") +'/'+ video_ID + '.mp4';

I hope this helps.

As you've noticed, you have no selectivity to your update statement so it is updating your entire table. If you want to update specific rows (ie where the IDs match) you probably want to do a coordinated subquery.

However, since you are using Oracle, it might be easier to create a materialized view for your query table and let Oracle's transaction mechanism handle the details. MVs work exactly like a table for querying semantics, are quite easy to set up, and allow you to specify the refresh interval.

You'll need to compile it using:

g++ inputfile.cpp -o outputbinary

The file you are referring has a missing #include <cstdlib> directive, if you also include that in your file, everything shall compile fine.

What is the difference between sorted(list) vs list.sort()?

• list.sort mutates the list in-place & returns None
• sorted takes any iterable & returns a new list, sorted.

sorted is equivalent to this Python implementation, but the CPython builtin function should run measurably faster as it is written in C:

def sorted(iterable, key=None):
    new_list = list(iterable)    # make a new list
    new_list.sort(key=key)       # sort it
    return new_list              # return it

when to use which?

• Use list.sort when you do not wish to retain the original sort order (Thus you will be able to reuse the list in-place in memory.) and when you are the sole owner of the list (if the list is shared by other code and you mutate it, you could introduce bugs where that list is used.)
• Use sorted when you want to retain the original sort order or when you wish to create a new list that only your local code owns.

Can a list's original positions be retrieved after list.sort()?

No - unless you made a copy yourself, that information is lost because the sort is done in-place.

"And which is faster? And how much faster?"

To illustrate the penalty of creating a new list, use the timeit module, here's our setup:

import timeit
setup = """
import random
lists = [list(range(10000)) for _ in range(1000)]  # list of lists
for l in lists:
    random.shuffle(l) # shuffle each list
shuffled_iter = iter(lists) # wrap as iterator so next() yields one at a time
"""

And here's our results for a list of randomly arranged 10000 integers, as we can see here, we've disproven an older list creation expense myth:

Python 2.7

>>> timeit.repeat("next(shuffled_iter).sort()", setup=setup, number = 1000)
[3.75168503401801, 3.7473005310166627, 3.753129180986434]
>>> timeit.repeat("sorted(next(shuffled_iter))", setup=setup, number = 1000)
[3.702025591977872, 3.709248117986135, 3.71071034099441]

Python 3

>>> timeit.repeat("next(shuffled_iter).sort()", setup=setup, number = 1000)
[2.797430992126465, 2.796825885772705, 2.7744789123535156]
>>> timeit.repeat("sorted(next(shuffled_iter))", setup=setup, number = 1000)
[2.675589084625244, 2.8019039630889893, 2.849375009536743]

After some feedback, I decided another test would be desirable with different characteristics. Here I provide the same randomly ordered list of 100,000 in length for each iteration 1,000 times.

import timeit
setup = """
import random
random.seed(0)
lst = list(range(100000))
random.shuffle(lst)
"""

I interpret this larger sort's difference coming from the copying mentioned by Martijn, but it does not dominate to the point stated in the older more popular answer here, here the increase in time is only about 10%

>>> timeit.repeat("lst[:].sort()", setup=setup, number = 10000)
[572.919036605, 573.1384446719999, 568.5923951]
>>> timeit.repeat("sorted(lst[:])", setup=setup, number = 10000)
[647.0584738299999, 653.4040515829997, 657.9457361929999]

I also ran the above on a much smaller sort, and saw that the new sorted copy version still takes about 2% longer running time on a sort of 1000 length.

Poke ran his own code as well, here's the code:

setup = '''
import random
random.seed(12122353453462456)
lst = list(range({length}))
random.shuffle(lst)
lists = [lst[:] for _ in range({repeats})]
it = iter(lists)
'''
t1 = 'l = next(it); l.sort()'
t2 = 'l = next(it); sorted(l)'
length = 10 ** 7
repeats = 10 ** 2
print(length, repeats)
for t in t1, t2:
    print(t)
    print(timeit(t, setup=setup.format(length=length, repeats=repeats), number=repeats))

He found for 1000000 length sort, (ran 100 times) a similar result, but only about a 5% increase in time, here's the output:

10000000 100
l = next(it); l.sort()
610.5015971539542
l = next(it); sorted(l)
646.7786222379655

Conclusion:

A large sized list being sorted with sorted making a copy will likely dominate differences, but the sorting itself dominates the operation, and organizing your code around these differences would be premature optimization. I would use sorted when I need a new sorted list of the data, and I would use list.sort when I need to sort a list in-place, and let that determine my usage.

Create a repository folder under your project. Let's take

${project.basedir}/src/main/resources/repo

Then, install your custom jar to this repo:

mvn install:install-file -Dfile=[FILE_PATH] \
-DgroupId=[GROUP] -DartifactId=[ARTIFACT] -Dversion=[VERS] \ 
-Dpackaging=jar -DlocalRepositoryPath=[REPO_DIR]

Lastly, add the following repo and dependency definitions to the projects pom.xml:

<repositories>
    <repository>
        <id>project-repo</id>
        <url>file://${project.basedir}/src/main/resources/repo</url>

@fthiella 's solution is very elegant.

If in future you want show more than user_id you could use joins, and there in one line could be all data you need.

If you want to use AND conditions, and the conditions are in multiple lines in your table, you can use JOINS example:

SELECT `w_name`.`user_id` 
     FROM `wp_usermeta` as `w_name`
     JOIN `wp_usermeta` as `w_year` ON `w_name`.`user_id`=`w_year`.`user_id` 
          AND `w_name`.`meta_key` = 'first_name' 
          AND `w_year`.`meta_key` = 'yearofpassing' 
     JOIN `wp_usermeta` as `w_city` ON `w_name`.`user_id`=`w_city`.user_id 
          AND `w_city`.`meta_key` = 'u_city'
     JOIN `wp_usermeta` as `w_course` ON `w_name`.`user_id`=`w_course`.`user_id` 
          AND `w_course`.`meta_key` = 'us_course'
     WHERE 
         `w_name`.`meta_value` = '$us_name' AND         
         `w_year`.meta_value   = '$us_yearselect' AND 
         `w_city`.`meta_value` = '$us_reg' AND 
         `w_course`.`meta_value` = '$us_course'

Other thing: Recommend to use prepared statements, because mysql_* functions is not SQL injection save, and will be deprecated. If you want to change your code the less as possible, you can use mysqli_ functions: http://php.net/manual/en/book.mysqli.php

Recommendation:

Use indexes in this table. user_id highly recommend to be and index, and recommend to be the meta_key AND meta_value too, for faster run of query.

The explain:

If you use AND you 'connect' the conditions for one line. So if you want AND condition for multiple lines, first you must create one line from multiple lines, like this.

So it should works.

This sort of thing is one of the logistical reasons why Abort is deprecated. First and foremost, do not use Thread.Abort() to cancel or stop a thread if at all possible. Abort() should only be used to forcefully kill a thread that is not responding to more peaceful requests to stop in a timely fashion.

That being said, you need to provide a shared cancellation indicator that one thread sets and waits while the other thread periodically checks and gracefully exits. .NET 4 includes a structure designed specifically for this purpose, the CancellationToken.

I encountered this issue today. the issue has to do with the $config['base_url'] . I noticed htpp://www.domain.com and http://example.com was the issue. to fix , always set your base_url to http://www.example.com

For me it was my internet, I was working on restricted network

Nginx works as a front end server, which in this case proxies the requests to a node.js server. Therefore you need to setup an nginx config file for node.

This is what I have done in my Ubuntu box:

Create the file yourdomain.com at /etc/nginx/sites-available/:

vim /etc/nginx/sites-available/yourdomain.com

In it you should have something like:

# the IP(s) on which your node server is running. I chose port 3000.
upstream app_yourdomain {
    server 127.0.0.1:3000;
    keepalive 8;
}

# the nginx server instance
server {
    listen 80;
    listen [::]:80;
    server_name yourdomain.com www.yourdomain.com;
    access_log /var/log/nginx/yourdomain.com.log;

    # pass the request to the node.js server with the correct headers
    # and much more can be added, see nginx config options
    location / {
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header Host $http_host;
      proxy_set_header X-NginX-Proxy true;

      proxy_pass http://app_yourdomain/;
      proxy_redirect off;
    }
 }

If you want nginx (>= 1.3.13) to handle websocket requests as well, add the following lines in the location / section:

proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";

Once you have this setup you must enable the site defined in the config file above:

cd /etc/nginx/sites-enabled/ 
ln -s /etc/nginx/sites-available/yourdomain.com yourdomain.com

Create your node server app at /var/www/yourdomain/app.js and run it at localhost:3000

var http = require('http');

http.createServer(function (req, res) {
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('Hello World\n');
}).listen(3000, "127.0.0.1");
console.log('Server running at http://127.0.0.1:3000/');

Test for syntax mistakes:

nginx -t

Restart nginx:

sudo /etc/init.d/nginx restart

Lastly start the node server:

cd /var/www/yourdomain/ && node app.js

Now you should see "Hello World" at yourdomain.com

One last note with regards to starting the node server: you should use some kind of monitoring system for the node daemon. There is an awesome tutorial on node with upstart and monit.

SELECT ID, 
    abc = STUFF(
                 (SELECT ',' + name FROM temp1 FOR XML PATH ('')), 1, 1, ''
               ) 
FROM temp1 GROUP BY id

Here in the above query STUFF function is used to just remove the first comma (,) from the generated xml string (,aaa,bbb,ccc,ddd,eee) then it will become (aaa,bbb,ccc,ddd,eee).

And FOR XML PATH('') simply converts column data into (,aaa,bbb,ccc,ddd,eee) string but in PATH we are passing '' so it will not create a XML tag.

And at the end we have grouped records using ID column.

What about cloning the repo elsewhere, and doing git log on both the real checkout and the fresh clone to see if you got the same thing.

The SqlException has a Number property that you can check. For duplicate error the number is 2601.

catch (SqlException e)
{
   switch (e.Number)
   {
      case 2601:
         // Do something.
         break;
      default:
         throw;
   }
 }

To get a list of all SQL errors from you server, try this:

 SELECT * FROM sysmessages

Update

This can now be simplified in C# 6.0

catch (SqlException e) when (e.Number == 2601)
{
   // Do something.
}

I made this plugin. There is some css interference taking place.

It's your border on the slider itself. Either use

box-sizing: border-box 

to absorb the border width, or put the border on the content inside the slide.

This happens because you are using the default CSRV middleware from Laravel's installation. To solve, remove this line from your Kernel.php:

\App\Http\Middleware\VerifyCsrfToken::class,

This is fine if you are build an API. However, if you are building a website this is a security verification, so be aware of its risks.

function resizeWindow(){
    var evt = document.createEvent('UIEvents');
    evt.initUIEvent('resize', true, false,window,0);
    window.dispatchEvent(evt); 
}

call this function after 500 milliseconds.

    if((number%1)!=0)
    {
        System.out.println("not a integer");
    }
    else
    {
        System.out.println("integer");
    }

You can do the following:

<script type='text/javascript'>
    document.body.onclick(function(){
        var myVariable = <?php echo(json_encode($myVariable)); ?>;
    };
</script>

If you want to append this css file to header you can do it using mounted() function of the vue file. See the example.
Note: Assume you can access the css file as http://www.yoursite/assets/styles/vendor.css in the browser.

mounted() {
        let style = document.createElement('link');
        style.type = "text/css";
        style.rel = "stylesheet";
        style.href = '/assets/styles/vendor.css';
        document.head.appendChild(style);
    }

To convert this bytesarray directly to json, you could first convert the bytesarray to a string with decode(), utf-8 is standard. Change the quotation markers.. The last step is to remove the " from the dumped string, to change the json object from string to list.

dumps(s.decode()).replace("'", '"')[1:-1]

Try this:

document.addEventListener("keydown", KeyCheck);  //or however you are calling your method
function KeyCheck(event)
{
   var KeyID = event.keyCode;
   switch(KeyID)
   {
      case 8:
      alert("backspace");
      break; 
      case 46:
      alert("delete");
      break;
      default:
      break;
   }
}

This will work in swift4 and swift5.

let dataDict = "the dictionary you want to convert in jsonString" 

let jsonData = try! JSONSerialization.data(withJSONObject: dataDict, options: JSONSerialization.WritingOptions.prettyPrinted)

let jsonString = NSString(data: jsonData, encoding: String.Encoding.utf8.rawValue)! as String

print(jsonString)

This works in Bash without forking external commands:

function has_substring() {
   [[ "$1" != "${2/$1/}" ]]
}

Example usage:

name="hello/world"
if has_substring "$name" "/"
then
   echo "Indeed, $name contains a slash!"
fi

You need use JSON.parse() for convert String into a Object:

var obj = JSON.parse('{ "firstName":"name1", "lastName": "last1" }');

Unique Approach

(Will work for Dialog, Fragment, Even Util class etc...)

ApplicationContext.getInstance().toast("I am toast");

Add below code in Application class accordingly.

public class ApplicationContext extends Application {

private static ApplicationContext instance;

@Override
public void onCreate() {
    super.onCreate();
    instance = this;
}

public static void toast(String message) {
    Toast.makeText(getContext(), message, Toast.LENGTH_SHORT).show();
}
}

You need to use an anonymous function like this:

$('.leadtoscore').click(function() {
  add_event('shot')
});

You can call it like you have in the example, just a function name without parameters, like this:

$('.leadtoscore').click(add_event);

But the add_event method won't get 'shot' as it's parameter, but rather whatever click passes to it's callback, which is the event object itself...so it's not applicable in this case, but works for many others. If you need to pass parameters, use an anonymous function...or, there's one other option, use .bind() and pass data, like this:

$('.leadtoscore').bind('click', { param: 'shot' }, add_event);

And access it in add_event, like this:

function add_event(event) {
  //event.data.param == "shot", use as needed
}

In addition to the Eclipse solutions and the tool mentioned in another answer, consider flip. It can 'flip' either way between normal and Windows linebreaks, and does nice things like preserve the file's timestamp and other stats.

You can use it like this to solve your problem:

find . -type f -not -path './.git/*' -exec flip -u {} \;

(I put in a clause to ignore your .git directory, in case you use git, but since flip ignores binary files by default, you mightn't need this.)

This is a late addition but I was looking for information on the scale function myself and though it might help somebody else as well.

To modify the response from Ricardo Saporta a little bit.
Scaling is not done using standard deviation, at least not in version 3.6.1 of R, I base this on "Becker, R. (2018). The new S language. CRC Press." and my own experimentation.

X.man.scaled <- X/sqrt(sum(X^2)/(length(X)-1))
X.aut.scaled <- scale(X, center = F)

The result of these rows are exactly the same, I show it without centering because of simplicity.

I would respond in a comment but did not have enough reputation.

Specifically, the MySQLi extension provides the following extremely useful benefits over the old MySQL extension..

OOP Interface (in addition to procedural) Prepared Statement Support Transaction + Stored Procedure Support Nicer Syntax Speed Improvements Enhanced Debugging

PDO Extension

PHP Data Objects extension is a Database Abstraction Layer. Specifically, this is not a MySQL interface, as it provides drivers for many database engines (of course including MYSQL).

PDO aims to provide a consistent API that means when a database engine is changed, the code changes to reflect this should be minimal. When using PDO, your code will normally "just work" across many database engines, simply by changing the driver you're using.

In addition to being cross-database compatible, PDO also supports prepared statements, stored procedures and more, whilst using the MySQL Driver.

There are couple of different solutions to achieve this:

1 - Native javascript for-in loop:

const result = {};
let key;

for (key in obj1) {
  if(obj1.hasOwnProperty(key)){
    result[key] = obj1[key];
  }
}

for (key in obj2) {
  if(obj2.hasOwnProperty(key)){
    result[key] = obj2[key];
  }
}

2 - Object.keys():

const result = {};

Object.keys(obj1)
  .forEach(key => result[key] = obj1[key]);

Object.keys(obj2)
  .forEach(key => result[key] = obj2[key]);

3 - Object.assign():
(Browser compatibility: Chrome: 45, Firefox (Gecko): 34, Internet Explorer: No support, Edge: (Yes), Opera: 32, Safari: 9)

const result = Object.assign({}, obj1, obj2);

4 - Spread Operator:
Standardised from ECMAScript 2015 (6th Edition, ECMA-262):

Defined in several sections of the specification: Array Initializer, Argument Lists

Using this new syntax you could join/merge different objects into one object like this:

const result = {
  ...obj1,
  ...obj2,
};

5 - jQuery.extend(target, obj1, obj2):

Merge the contents of two or more objects together into the first object.

const target = {};

$.extend(target, obj1, obj2);

6 - jQuery.extend(true, target, obj1, obj2):

Run a deep merge of the contents of two or more objects together into the target. Passing false for the first argument is not supported.

const target = {};

$.extend(true, target, obj1, obj2);

7 - Lodash _.assignIn(object, [sources]): also named as _.extend:

const result = {};

_.assignIn(result, obj1, obj2);

8 - Lodash _.merge(object, [sources]):

const result = _.merge(obj1, obj2);

There are a couple of important differences between lodash's merge function and Object.assign:

1- Although they both receive any number of objects but lodash's merge apply a deep merge of those objects but Object.assign only merges the first level. For instance:

_.isEqual(_.merge({
  x: {
    y: { key1: 'value1' },
  },
}, {
  x: {
    y: { key2: 'value2' },
  },
}), {
  x: {
    y: {
      key1: 'value1',
      key2: 'value2',
    },
  },
}); // true

BUT:

const result = Object.assign({
  x: {
    y: { key1: 'value1' },
  },
}, {
  x: {
    y: { key2: 'value2' },
  },
});
_.isEqual(result, {
  x: {
    y: {
      key1: 'value1',
      key2: 'value2',
    },
  },
}); // false
// AND
_.isEqual(result, {
  x: {
    y: {
      key2: 'value2',
    },
  },
}); // true

2- Another difference has to do with how Object.assign and _.merge interpret the undefined value:

_.isEqual(_.merge({x: 1}, {x: undefined}), { x: 1 }) // false

BUT:

_.isEqual(Object.assign({x: 1}, {x: undefined}), { x: undefined })// true

Update 1:

When using for in loop in JavaScript, we should be aware of our environment specially the possible prototype changes in the JavaScript types. For instance some of the older JavaScript libraries add new stuff to Array.prototype or even Object.prototype. To safeguard your iterations over from the added stuff we could use object.hasOwnProperty(key) to mke sure the key is actually part of the object you are iterating over.

Update 2:

I updated my answer and added the solution number 4, which is a new JavaScript feature but not completely standardized yet. I am using it with Babeljs which is a compiler for writing next generation JavaScript.

Update 3:
I added the difference between Object.assign and _.merge.

If working with data, many times pandas is the simple key

This particular code will put the raw into one column, then normalize by column per row. (But we can put it into a row and do it by row per column, too! Just have to change the axis values where 0 is for row and 1 is for column.)

import pandas as pd


raw = [0.07, 0.14, 0.07]  

raw_df = pd.DataFrame(raw)
normed_df = raw_df.div(raw_df.sum(axis=0), axis=1)
normed_df

where normed_df will display like:

    0
0   0.25
1   0.50
2   0.25

and then can keep playing with the data, too!

Two approaches:

• When you login: you can to create a copy_my_files.bat file into your All Programs > Startup folder with this content (its a plain text document):

  • xcopy c:\folder\*.* d:\another_folder\.

  Use xcopy c:\folder\*.* d:\another_folder\. /Y to overwrite the file without any prompt.

• Everytime a folder changes: if you can to use C#, you can to create a program using FileSystemWatcher

Just create a new branch:

git checkout -b newBranch

And if you do git status you'll see that the state of the code hasn't changed and you can commit it to the new branch.

Use os.path.getsize(path) which will

Return the size, in bytes, of path. Raise OSError if the file does not exist or is inaccessible.

import os
os.path.getsize('C:\\Python27\\Lib\\genericpath.py')

Or use os.stat(path).st_size

import os
os.stat('C:\\Python27\\Lib\\genericpath.py').st_size 

Or use Path(path).stat().st_size (Python 3.4+)

from pathlib import Path
Path('C:\\Python27\\Lib\\genericpath.py').stat().st_size

MediaQuery.of(context).size.width

You need to define the output parameter as an output parameter in the code with the ParameterDirection.Output enumeration. There are numerous examples of this out there, but here's one on MSDN.

Try this -

<table align="center" style="margin: 0px auto;"></table>

Having a hidden input field leads to problems with datepicker dialog positioning (dialog is horizontally centered). You could alter the dialog's margin, but there's a better way.

Just create an input field and "hide" it by setting it's opacity to 0 and making it 1px wide. Also position it near (or under) the button, or where ever you want the datepicker to appear.

Then attach the datepicker to the "hidden" input field and show it when user presses the button.

HTML:

<button id="date-button">Show Calendar</button>
<input type="text" name="date-field" id="date-field" value="">

CSS:

#date-button {
    position: absolute;
    top: 0;
    left: 0;
    z-index: 2;
    height 30px;
}

#date-field {
    position: absolute;
    top: 0;
    left: 0;
    z-index: 1;
    width: 1px;
    height: 32px; // height of the button + a little margin
    opacity: 0;
}

JS:

$(function() {
   $('#date-field').datepicker();

   $('#date-button').on('click', function() {
      $('#date-field').datepicker('show');
   });
});

Note: not tested with all browsers.

As drew_w said, you can find a good example here.

You can add them in your htaccess file or vhost configuration.

But unless you own those domains .. they are our of your control.

Just because this is what I got when I Googled this error, my problem was that I had

if (value < other.value)
  return -1;
else if (value >= other.value)
  return 1;
else
  return 0;

the value >= other.value should (obviously) actually be value > other.value so that you can actually return 0 with equal objects.

This came from a time before Java 1.5 exists and bring enums to us. Prior to that, there was no good way to define a set of constants or constrained values.

This is still used, most of the time either for backward compatibility or due to the amount of refactoring needed to get rid off, in a lot of project.

Help is your best saviour, there is a logs action that you can call to check logs for all running processes.

You want to add libraries to your project and in doing so you have two options as you yourself identified:

Compile-time libraries are libraries which is needed to compile your application. They are not included when your application is assembled (e.g., into a war-file). Libraries of this kind must be provided by the container running your project.

This is useful in situation when you want to vary API and implementation, or when the library is supplied by the container (which is typically the case with javax.servlet which is required to compile but provided by the application server, e.g., Apache Tomcat).

Run-time libraries are libraries which is needed both for compilation and when running your project. This is probably what you want in most cases. If for instance your project is packaged into a war/ear, then these libraries will be included in the package.

As for the other alernatives you have either global libraries using Library Manageror jdk libraries. The latter is simply your regular java libraries, while the former is just a way for your to store a set of libraries under a common name. For all your future projects, instead of manually assigning the libraries you can simply select to import them from your Library Manager.

I like Daniel Cerecedo's answer using toJSON() and regex. An even simpler form would be:

var now = new Date();
var regex = /^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}).*$/;
var token_array = regex.exec(now.toJSON());
// [ "2017-10-31T02:24:45.868Z", "2017", "10", "31", "02", "24", "45" ]
var myFormat = token_array.slice(1).join('');
// "20171031022445"

there's a bootstrap function to change the color of table header called thead-dark for dark background of table header and thead-light for light background of table header. Your code will look like this after using this function.

<table class="table">
    <tr class="thead-danger">
        <!-- here I used dark table headre -->
        <th>
            @Html.DisplayNameFor(model => model.name)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.checkBox1)
        </th>
        <th></th>
    </tr>

For joins, I strongly prefer query-syntax for all the details that are happily hidden (not the least of which are the transparent identifiers involved with the intermediate projections along the way that are apparent in the dot-syntax equivalent). However, you asked regarding Lambdas which I think you have everything you need - you just need to put it all together.

var categorizedProducts = product
    .Join(productcategory, p => p.Id, pc => pc.ProdId, (p, pc) => new { p, pc })
    .Join(category, ppc => ppc.pc.CatId, c => c.Id, (ppc, c) => new { ppc, c })
    .Select(m => new { 
        ProdId = m.ppc.p.Id, // or m.ppc.pc.ProdId
        CatId = m.c.CatId
        // other assignments
    });

If you need to, you can save the join into a local variable and reuse it later, however lacking other details to the contrary, I see no reason to introduce the local variable.

Also, you could throw the Select into the last lambda of the second Join (again, provided there are no other operations that depend on the join results) which would give:

var categorizedProducts = product
    .Join(productcategory, p => p.Id, pc => pc.ProdId, (p, pc) => new { p, pc })
    .Join(category, ppc => ppc.pc.CatId, c => c.Id, (ppc, c) => new {
        ProdId = ppc.p.Id, // or ppc.pc.ProdId
        CatId = c.CatId
        // other assignments
    });

...and making a last attempt to sell you on query syntax, this would look like this:

var categorizedProducts =
    from p in product
    join pc in productcategory on p.Id equals pc.ProdId
    join c in category on pc.CatId equals c.Id
    select new {
        ProdId = p.Id, // or pc.ProdId
        CatId = c.CatId
        // other assignments
    };

Your hands may be tied on whether query-syntax is available. I know some shops have such mandates - often based on the notion that query-syntax is somewhat more limited than dot-syntax. There are other reasons, like "why should I learn a second syntax if I can do everything and more in dot-syntax?" As this last part shows - there are details that query-syntax hides that can make it well worth embracing with the improvement to readability it brings: all those intermediate projections and identifiers you have to cook-up are happily not front-and-center-stage in the query-syntax version - they are background fluff. Off my soap-box now - anyhow, thanks for the question. :)

NULL has no value, and so cannot be compared using the scalar value operators.

In other words, no value can ever be equal to (or not equal to) NULL because NULL has no value.

Hence, SQL has special IS NULL and IS NOT NULL predicates for dealing with NULL.

I use JuJu which basically allows to have a really tiny linux distribution (containing just the package manager) inside your $HOME/.juju directory.

It allows to have your custom system inside the home directory accessible via proot and, therefore, you can install any packages without root privileges. It will run properly to all the major linux distributions, the only limitation is that JuJu can run on linux kernel with minimum reccomended version 2.6.32.

For instance, after installed JuJu to install pip just type the following:

$>juju -f
(juju)$> pacman -S python-pip
(juju)> pip

Try-catch

If variable was not defined at all, you can check this without break code execution using try-catch block as follows (you don't need to use strict mode)

try{
  notDefinedVariable;
} catch(e) {
  console.log('detected: variable not exists');
}

console.log('but the code is still executed');

notDefinedVariable; // without try-catch wrapper code stops here

console.log('code execution stops. You will NOT see this message on console');

BONUS: (referring to other answers) Why === is more clear than == (source)

if( a == b )

if( a === b )

If you want to change ng-view you'll have to use the '#'

If you want to return IHttpActionResult you can do it like this:

[HttpGet]
public IHttpActionResult Test()
{
    var stream = new MemoryStream();

    var result = new HttpResponseMessage(HttpStatusCode.OK)
    {
        Content = new ByteArrayContent(stream.GetBuffer())
    };
    result.Content.Headers.ContentDisposition = new System.Net.Http.Headers.ContentDispositionHeaderValue("attachment")
    {
        FileName = "test.pdf"
    };
    result.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");

    var response = ResponseMessage(result);

    return response;
}

Alternatively to the answer marked as correct, if you have to replace words instead of chars you can do it with this piece of code :

$query = "INSERT INTO my_table VALUES (?, ?, ?, ?);";
$values = Array("apple", "oranges", "mangos", "papayas");
foreach (array_fill(0, count($values), '?') as $key => $wildcard) {
    $query = substr_replace($query, '"'.$values[$key].'"', strpos($query, $wildcard), strlen($wildcard));
}
echo $query;

    $objPHPExcel = new PHPExcel();

                                 ->setTitle("Office 2007 XLSX Test Document")
                                 ->setSubject("Office 2007 XLSX Test Document")

                                 ->setCategory("Test result file");
    $objPHPExcel->setActiveSheetIndex(0);
    $sheet = $objPHPExcel->getActiveSheet();
    $sheet->setCellValue('A1', 'No');
    $sheet->setCellValue('B1', 'Job ID');

    $sheet->setCellValue('D1', 'Job Archived Date');
    $styleArray = array(
        'font' => array(

As nice as "return by value" might be, it's the kind of code that can lead one into error. Consider the following program:

    #include <string>
    #include <vector>
    #include <iostream>
    using namespace std;
    static std::vector<std::string> strings;
    std::vector<std::string> vecFunc(void) { return strings; };
    int main(int argc, char * argv[]){
      // set up the vector of strings to hold however
      // many strings the user provides on the command line
      for(int idx=1; (idx<argc); ++idx){
         strings.push_back(argv[idx]);
      }

      // now, iterate the strings and print them using the vector function
      // as accessor
      for(std::vector<std::string>::interator idx=vecFunc().begin(); (idx!=vecFunc().end()); ++idx){
         cout << "Addr: " << idx->c_str() << std::endl;
         cout << "Val:  " << *idx << std::endl;
      }
    return 0;
    };

• Q: What will happen when the above is executed? A: A coredump.
• Q: Why didn't the compiler catch the mistake? A: Because the program is syntactically, although not semantically, correct.
• Q: What happens if you modify vecFunc() to return a reference? A: The program runs to completion and produces the expected result.
• Q: What is the difference? A: The compiler does not have to create and manage anonymous objects. The programmer has instructed the compiler to use exactly one object for the iterator and for endpoint determination, rather than two different objects as the broken example does.

The above erroneous program will indicate no errors even if one uses the GNU g++ reporting options -Wall -Wextra -Weffc++

If you must produce a value, then the following would work in place of calling vecFunc() twice:

   std::vector<std::string> lclvec(vecFunc());
   for(std::vector<std::string>::iterator idx=lclvec.begin(); (idx!=lclvec.end()); ++idx)...

The above also produces no anonymous objects during iteration of the loop, but requires a possible copy operation (which, as some note, might be optimized away under some circumstances. But the reference method guarantees that no copy will be produced. Believing the compiler will perform RVO is no substitute for trying to build the most efficient code you can. If you can moot the need for the compiler to do RVO, you are ahead of the game.

Facebook does not allow you to change the "What's on your mind?" text box, unless of course you're developing an application for use on Facebook.

Try to login via the terminal using the following command:

mysql -u root -p

It will then prompt for your password. If this fails, then definitely the username or password is incorrect. If this works, then your database's password needs to be enclosed in quotes:

database_password: "0000"

Use below method, just pass the subject and body as arguments of the method

public static void shareText(String subject,String body) {
    Intent txtIntent = new Intent(android.content.Intent.ACTION_SEND);
    txtIntent .setType("text/plain");
    txtIntent .putExtra(android.content.Intent.EXTRA_SUBJECT, subject);
    txtIntent .putExtra(android.content.Intent.EXTRA_TEXT, body);
    startActivity(Intent.createChooser(txtIntent ,"Share"));
}

Try downloading the certificates/profiles directly from the member centre rather than doing it from Xcode.

It worked for me when I manually downloaded them from the member centre.

The word "canonical" is just a synonym for "standard" or "usual". It doesn`t have any Java-specific meaning.

If the array is unsorted, you will need to use linear search.

For Fedora:

# Fedora 18 or greater
sudo dnf group install "MinGW cross-compiler"

# Or (not recommended, because of its deprecation)
sudo yum groupinstall -y "MinGW cross-compiler"

Here is simple example. A contact has one to many associated phone numbers. When a contact is deleted, I want all its associated phone numbers to also be deleted, so I use ON DELETE CASCADE. The one-to-many/many-to-one relationship is implemented with by the foreign key in the phone_numbers.

CREATE TABLE contacts
 (contact_id BIGINT AUTO_INCREMENT NOT NULL,
 name VARCHAR(75) NOT NULL,
 PRIMARY KEY(contact_id)) ENGINE = InnoDB;

CREATE TABLE phone_numbers
 (phone_id BIGINT AUTO_INCREMENT NOT NULL,
  phone_number CHAR(10) NOT NULL,
 contact_id BIGINT NOT NULL,
 PRIMARY KEY(phone_id),
 UNIQUE(phone_number)) ENGINE = InnoDB;

ALTER TABLE phone_numbers ADD FOREIGN KEY (contact_id) REFERENCES \
contacts(contact_id) ) ON DELETE CASCADE;

By adding "ON DELETE CASCADE" to the foreign key constraint, phone_numbers will automatically be deleted when their associated contact is deleted.

INSERT INTO table contacts(name) VALUES('Robert Smith');
INSERT INTO table phone_numbers(phone_number, contact_id) VALUES('8963333333', 1);
INSERT INTO table phone_numbers(phone_number, contact_id) VALUES('8964444444', 1);

Now when a row in the contacts table is deleted, all its associated phone_numbers rows will automatically be deleted.

DELETE TABLE contacts as c WHERE c.id=1; /* delete cascades to phone_numbers */

To achieve the same thing in Doctrine, to get the same DB-level "ON DELETE CASCADE" behavoir, you configure the @JoinColumn with the onDelete="CASCADE" option.

If you now do

# doctrine orm:schema-tool:create --dump-sql

you will see that the same SQL will be generated as in the first, raw-SQL example

You can either use the numerical indices ($row[0]) or better, use AS in the MySQL:

SELECT *, user.id AS user_id FROM ...

If you are using Angular and Firebase, you can also use the DTOptionsBuilder :

angular.module('your_module', [
'ui.router',
'oc.lazyLoad',
'ui.bootstrap',
'ngSanitize',
'firebase']).controller("your_controller", function ($scope, $firebaseArray, DTOptionsBuilder) {

var ref = firebase.database().ref().child("your_database_table");

// create a synchronized array
$scope.your_database_table = $firebaseArray(ref);

ref.on('value', snap => {

    $scope.dtOptions = DTOptionsBuilder.newOptions()
        .withOption('language',
        {
            "sProcessing": "Traitement en cours...",
            "sSearch": "Rechercher :",
            "sLengthMenu": "Afficher _MENU_ éléments",
            "sInfo": "Affichage de l'élément _START_ à _END_ sur _TOTAL_ éléments",
            "sInfoEmpty": "Affichage de l'élément 0 à 0 sur 0 élément",
            "sInfoFiltered": "(filtré de _MAX_ éléments au total)",
            "sInfoPostFix": "",
            "sLoadingRecords": "Chargement en cours...",
            "sZeroRecords": "Aucun élément à afficher",
            "sEmptyTable": "Aucune donnée disponible dans le tableau",
            "oPaginate": {
                "sFirst": "Premier",
                "sPrevious": "Précédent",
                "sNext": "Suivant",
                "sLast": "Dernier"
            },
            "oAria": {
                "sSortAscending": ": activer pour trier la colonne par ordre croissant",
                "sSortDescending": ": activer pour trier la colonne par ordre décroissant"
            }
        }
        )

});})

I hope this will help.

instead of os.walk, just use os.listdir

If you only want it to iterate over your HashMap, no need for a list:

HashMap<Integer, String> map = new HashMap<Integer, String>();
map.put (1, "Mark");
map.put (2, "Tarryn");
for (String s : map.values()) {
    System.out.println(s);
}

Of course, if you want to modify your map structurally (i.e. more than only changing the value for an existing key) while iterating, then you better use the "copy to ArrayList" method, since otherwise you'll get a ConcurrentModificationException. Or export as an array:

HashMap<Integer, String> map = new HashMap<Integer, String>();
map.put (1, "Mark");
map.put (2, "Tarryn");
for (String s : map.values().toArray(new String[]{})) {
    System.out.println(s);
}

You could create a little class that returns the boolean result of calling match, and retains the matched groups for subsequent retrieval:

import re

class REMatcher(object):
    def __init__(self, matchstring):
        self.matchstring = matchstring

    def match(self,regexp):
        self.rematch = re.match(regexp, self.matchstring)
        return bool(self.rematch)

    def group(self,i):
        return self.rematch.group(i)


for statement in ("I love Mary", 
                  "Ich liebe Margot", 
                  "Je t'aime Marie", 
                  "Te amo Maria"):

    m = REMatcher(statement)

    if m.match(r"I love (\w+)"): 
        print "He loves",m.group(1) 

    elif m.match(r"Ich liebe (\w+)"):
        print "Er liebt",m.group(1) 

    elif m.match(r"Je t'aime (\w+)"):
        print "Il aime",m.group(1) 

    else: 
        print "???"

Update for Python 3 print as a function, and Python 3.8 assignment expressions - no need for a REMatcher class now:

import re

for statement in ("I love Mary",
                  "Ich liebe Margot",
                  "Je t'aime Marie",
                  "Te amo Maria"):

    if m := re.match(r"I love (\w+)", statement):
        print("He loves", m.group(1))

    elif m := re.match(r"Ich liebe (\w+)", statement):
        print("Er liebt", m.group(1))

    elif m := re.match(r"Je t'aime (\w+)", statement):
        print("Il aime", m.group(1))

    else:
        print()

From the context, the conflict was caused by the version of the package.
Let's take a look the manual about rpm:

--force
    Same as using --replacepkgs, --replacefiles, and --oldpackage.

--oldpackage
    Allow an upgrade to replace a newer package with an older one.

So, you can execute the command rpm -Uvh info-4.13a-2.rpm --force to solve your issue.

The usual WPF timer is the DispatcherTimer, which is not a control but used in code. It basically works the same way like the WinForms timer:

System.Windows.Threading.DispatcherTimer dispatcherTimer = new System.Windows.Threading.DispatcherTimer();
dispatcherTimer.Tick += dispatcherTimer_Tick;
dispatcherTimer.Interval = new TimeSpan(0,0,1);
dispatcherTimer.Start();


private void dispatcherTimer_Tick(object sender, EventArgs e)
{
  // code goes here
}

More on the DispatcherTimer can be found here

If you have both versions of PHP installed, you can switch between versions using the link and unlink brew commands.

For example, to switch between PHP 7.4 and PHP 7.3

brew unlink [email protected]
brew link [email protected]

PS: both versions of PHP have be installed for these commands to work.

primes = {x for x in range(2, 101) if all(x%y for y in range(2, min(x, 11)))}

I simplified the test a bit - if all(x%y instead of if not any(not x%y

I also limited y's range; there is no point in testing for divisors > sqrt(x). So max(x) == 100 implies max(y) == 10. For x <= 10, y must also be < x.

pairs = {(x, x+2) for x in primes if x+2 in primes}

Instead of generating pairs of primes and testing them, get one and see if the corresponding higher prime exists.

Override ui-page class in your css:

.ui-page {
    background: url("image.gif");
    background-repeat: repeat;
}

The string you are returning is not valid JSON. The names in the objects needs to be quoted and the whole string needs to be put in { … } to form an object. JSON also cannot contain something like new Date(). JSON is just a small subset of JavaScript that has only strings, numbers, objects, arrays, true, false and null.

See the JSON grammar for more information.

If you are using the 'pylab' for interactive plotting you can set the labelsize at creation time with pylab.ylabel('Example', fontsize=40).

If you use pyplot programmatically you can either set the fontsize on creation with ax.set_ylabel('Example', fontsize=40) or afterwards with ax.yaxis.label.set_size(40).

Easy way to achieve this in angular 2 or 4 (Assuming that you are using bootstrap 4)

One point from me. I used a mutual cert authentication with spring-boot microservices. The following is working for me, key points here are keyManagerFactory.init(...) and sslcontext.init(keyManagerFactory.getKeyManagers(), null, new SecureRandom()) lines of code without them, at least for me, things did not work. Certificates are packaged by PKCS12.

@Value("${server.ssl.key-store-password}")
private String keyStorePassword;
@Value("${server.ssl.key-store-type}")
private String keyStoreType;
@Value("${server.ssl.key-store}")
private Resource resource;

private RestTemplate getRestTemplate() throws Exception {
    return new RestTemplate(clientHttpRequestFactory());
}

private ClientHttpRequestFactory clientHttpRequestFactory() throws Exception {
    return new HttpComponentsClientHttpRequestFactory(httpClient());
}

private HttpClient httpClient() throws Exception {

    KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance("SunX509");
    KeyStore trustStore = KeyStore.getInstance(keyStoreType);

    if (resource.exists()) {
        InputStream inputStream = resource.getInputStream();

        try {
            if (inputStream != null) {
                trustStore.load(inputStream, keyStorePassword.toCharArray());
                keyManagerFactory.init(trustStore, keyStorePassword.toCharArray());
            }
        } finally {
            if (inputStream != null) {
                inputStream.close();
            }
        }
    } else {
        throw new RuntimeException("Cannot find resource: " + resource.getFilename());
    }

    SSLContext sslcontext = SSLContexts.custom().loadTrustMaterial(trustStore, new TrustSelfSignedStrategy()).build();
    sslcontext.init(keyManagerFactory.getKeyManagers(), null, new SecureRandom());
    SSLConnectionSocketFactory sslConnectionSocketFactory =

Create a table with column as type json

CREATE TABLE friends ( id serial primary key, data jsonb);

Now let's insert json data

INSERT INTO friends(data) VALUES ('{"name": "Arya", "work": ["Improvements", "Office"], "available": true}');
INSERT INTO friends(data) VALUES ('{"name": "Tim Cook", "work": ["Cook", "ceo", "Play"], "uses": ["baseball", "laptop"], "available": false}');

Now let's make some queries to fetch data

select data->'name' from friends;
select data->'name' as name, data->'work' as work from friends;

You might have noticed that the results comes with inverted comma( " ) and brackets ([ ])

    name    |            work            
------------+----------------------------
 "Arya"     | ["Improvements", "Office"]
 "Tim Cook" | ["Cook", "ceo", "Play"]
(2 rows)

Now to retrieve only the values just use ->>

select data->>'name' as name, data->'work'->>0 as work from friends;
select data->>'name' as name, data->'work'->>0 as work from friends where data->>'name'='Arya';

This worked for me:

sudo rm /var/lib/mongodb/mongod.lock    
sudo service mongodb restart

A number of years ago (in the IE only days) I was using the <col align="right"> tag, but I just tested it and and it seems to be an IE only feature:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
    "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
    <title>Test</title>
</head>
<body>
    <table width="100%" border="1">
        <col align="left" />
        <col align="left" />
        <col align="right" />
        <tr>
            <th>ISBN</th>
            <th>Title</th>
            <th>Price</th>
        </tr>
        <tr>
            <td>3476896</td>
            <td>My first HTML</td>
            <td>$53</td>
        </tr>
    </table>
</body>
</html>

The snippet is taken from www.w3schools.com. Of course, it should not be used (unless for some reason you really target the IE rendering engine only), but I thought it would be interesting to mention it.

Edit:

• IE still supports it.
• Firefox has dropped support in 3.5.
• Safari does not seem to support it, but the documentation indicates otherwise.

Overall, I don't understand the reasoning behing abandoning this tag. It would appear to be very useful (at least for manual HTML publishing).

I have read out very clear definitions for these terms.

Protected : Access is limited to within the class definition and any class that inherits from the class. The type or member can be accessed only by code in the same class or struct or in a class that is derived from that class.

Internal : Access is limited to exclusively to classes defined within the current project assembly. The type or member can be accessed only by code in same class.

Protected-Internal : Access is limited to current assembly or types derived from containing class.

Microsoft Access and LibreOffice Base can open a spreadsheet as a source and run sql queries on it. That would be the easiest way to run all kinds of queries, and avoid the mess of running macros or writing code.

Excel also has autofilters and data sorting that will accomplish a lot of simple queries like your example. If you need help with those features, Google would be a better source for tutorials than me.

Just an addition, to make it even more tiny:

$('#imgId').click(function(){
    $(this).attr("src",$(this).attr('src') == 'img1_on.gif' ? 'img1_off.gif':'img1_on.gif');
});

I found some issue about that kind of error

UPDATE 19-05-2017:

These url you must to visit from the IP address that will be send email

UPDATE: I had some time on my hands, so ... I went ahead and fleshed out this idea. See below for the code.

Here's a bit of a crazy answer:

You could do what you're looking for -- essentially treat a two-dimensional array as a table with rows -- by writing a static method (perhaps an extension method) that takes a T[,] and returns an IEnumerable<T[]>. This would require copying each "row" of the underlying table into a new array, though.

A perhaps better (though more involved) approach would be to actually write a class that implements IList<T> as a wrapper around a single "row" of a two-dimensional array (you would probably set IsReadOnly to true and just implement the getter for the this[int] property and probably Count and GetEnumerator; everything else could throw a NotSupportedException). Then your static/extension method could return an IEnumerable<IList<T>> and provide deferred execution.

That way you could write code pretty much like what you have:

foreach (IList<string> row in table.GetRows()) // or something
{
    Console.WriteLine(row[0] + " " + row[1]);
}

Just a thought.

Implementation suggestion:

public static class ArrayTableHelper {
    public static IEnumerable<IList<T>> GetRows<T>(this T[,] table) {
        for (int i = 0; i < table.GetLength(0); ++i)
            yield return new ArrayTableRow<T>(table, i);
    }

    private class ArrayTableRow<T> : IList<T> {
        private readonly T[,] _table;
        private readonly int _count;
        private readonly int _rowIndex;

        public ArrayTableRow(T[,] table, int rowIndex) {
            if (table == null)
                throw new ArgumentNullException("table");

            if (rowIndex < 0 || rowIndex >= table.GetLength(0))
                throw new ArgumentOutOfRangeException("rowIndex");

            _table = table;
            _count = _table.GetLength(1);
            _rowIndex = rowIndex;
        }

        // I didn't implement the setter below,
        // but you easily COULD (and then set IsReadOnly to false?)
        public T this[int index] {
            get { return _table[_rowIndex, index]; }
            set { throw new NotImplementedException(); }
        }

        public int Count {
            get { return _count; }
        }

        bool ICollection<T>.IsReadOnly {
            get { return true; }
        }

        public IEnumerator<T> GetEnumerator() {
            for (int i = 0; i < _count; ++i)
                yield return this[i];
        }

        // omitted remaining IList<T> members for brevity;
        // you actually could implement IndexOf, Contains, etc.
        // quite easily, though
    }
}

...now I think I should give StackOverflow a break for the rest of the day ;)

If you created new settings.xml file instead of copy it from somewhere else, remember to put the tag inside :

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 https://maven.apache.org/xsd/settings-1.0.0.xsd"> <proxies> ..... </proxies> </settings>

I've tried all the answers, but there was always something missing and not functioning as expected for me.

Then I experimented a bit with the hints given in each answer and was successful with the following setting:

<appender name="RollingActivityLog" type="log4net.Appender.RollingFileAppender">
  <file type="log4net.Util.PatternString" value="C:\temp\LOG4NET_Sample_Activity.log" />
  <appendToFile value="true" />
  <rollingStyle value="Date" />
  <staticLogFileName value="false" />
  <preserveLogFileNameExtension value="true" />
  <datePattern value="-yyyyMMdd" />
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date %-5level - %message%newline" />
  </layout>
</appender>

The issue with other combinations of parameters was that the latest file didn't have the time pattern, or that the time pattern was appended as .log20171215 which created a new file time (and a new file type!) each day - or both issues appeared.

Now with this setting you are getting files like this one:

LOG4NET_Sample_Activity-20171215.log

which is what I wanted.

To summarize:

• Don't put the date pattern in the <file value=... attribute, just define it in the datePattern.

• Make sure you have the preserveLogFileNameExtension value attribute set to true.

• Make sure you have the staticLogFileName value set to false.

• Set the rollingStyle attribute value to Date.

temp = open(filename,'r').read().split('\n')

The DataTable.Clone() method works great when you want to create a completely new DataTable, but there might be cases where you would want to add the schema columns from one DataTable to another existing DataTable.

For example, if you've derived a new subclass from DataTable, and want to import schema information into it, you couldn't use Clone().

E.g.:

public class CoolNewTable : DataTable {
   public void FillFromReader(DbDataReader reader) {
       // We want to get the schema information (i.e. columns) from the 
       // DbDataReader and 
       // import it into *this* DataTable, NOT a new one.
       DataTable schema = reader.GetSchemaTable(); 
       //GetSchemaTable() returns a DataTable with the columns we want.

       ImportSchema(this, schema); // <--- how do we do this?
   }
}

The answer is just to create new DataColumns in the existing DataTable using the schema table's columns as templates.

I.e. the code for ImportSchema would be something like this:

void ImportSchema(DataTable dest, DataTable source) {
    foreach(var c in source.Columns)
        dest.Columns.Add(c);
}

or, if you're using Linq:

void ImportSchema(DataTable dest, DataTable source) {
    var cols = source.Columns.Cast<DataColumn>().ToArray();
    dest.Columns.AddRange(cols);
}

This was just one example of a situation where you might want to copy schema/columns from one DataTable into another one without using Clone() to create a completely new DataTable. I'm sure I've come across several others as well.

For those wanting to update their existing data here is the query:

update SomeEventTable set eventTime=RIGHT('00000'+ISNULL(eventTime, ''),5)

Using LIKE will give you options for defining what the rest of the string should look like, but if the rule is just starts with 'NoHist_' it doesn't really matter.

If It is simple Session you can apply NULL Check directly Session["emp_num"] != null

But if it's a session of a list Item then You need to apply any one of the following option

Option 1:

if (((List<int>)(Session["emp_num"])) != null && (List<int>)Session["emp_num"])).Count > 0)
 {
 //Your Logic here
 }

Option 2:

List<int> val= Session["emp_num"] as List<int>;  //Get the value from Session.

if (val.FirstOrDefault() != null)
 {
 //Your Logic here
 }

You can call:

arr.slice(Math.max(arr.length - 5, 1))

If you don't want to exclude the first element, use

arr.slice(Math.max(arr.length - 5, 0))

The position: fixed; solution has a drawback - the page jumps to the top when this style is applied. Angular's Material Dialog has a nice solution, where they fake the scroll position by applying positioning to the html element.

Below is my revised algorithm for vertical scrolling only. Left scroll blocking is done in the exact same manner.

// This class applies the following styles:
// position: fixed;
// overflow-y: scroll;
// width: 100%;
const NO_SCROLL_CLASS = "bp-no-scroll";

const coerceCssPixelValue = value => {
  if (value == null) {
    return "";
  }

  return typeof value === "string" ? value : `${value}px`;
};

export const blockScroll = () => {
  const html = document.documentElement;
  const documentRect = html.getBoundingClientRect();
  const { body } = document;

  // Cache the current scroll position to be restored later.
  const cachedScrollPosition =
    -documentRect.top || body.scrollTop || window.scrollY || document.scrollTop || 0;

  // Cache the current inline `top` value in case the user has set it.
  const cachedHTMLTop = html.style.top || "";

  // Using `html` instead of `body`, because `body` may have a user agent margin,
  // whereas `html` is guaranteed not to have one.
  html.style.top = coerceCssPixelValue(-cachedScrollPosition);

  // Set the magic class.
  html.classList.add(NO_SCROLL_CLASS);

  // Return a function to remove the scroll block.
  return () => {
    const htmlStyle = html.style;
    const bodyStyle = body.style;

    // We will need to seamlessly restore the original scroll position using
    // `window.scroll`. To do that we will change the scroll behavior to `auto`.
    // Here we cache the current scroll behavior to restore it later.
    const previousHtmlScrollBehavior = htmlStyle.scrollBehavior || "";
    const previousBodyScrollBehavior = bodyStyle.scrollBehavior || "";

    // Restore the original inline `top` value.
    htmlStyle.top = cachedHTMLTop;

    // Remove the magic class.
    html.classList.remove(NO_SCROLL_CLASS);

    // Disable user-defined smooth scrolling temporarily while we restore the scroll position.
    htmlStyle.scrollBehavior = bodyStyle.scrollBehavior = "auto";

    // Restore the original scroll position.
    window.scroll({
      top: cachedScrollPosition.top
    });

    // Restore the original scroll behavior.
    htmlStyle.scrollBehavior = previousHtmlScrollBehavior;
    bodyStyle.scrollBehavior = previousBodyScrollBehavior;
  };
};

The logic is very simple and can be simplified even more if you don't care about certain edge cases. For example, this is what I use:

export const blockScroll = () => {
  const html = document.documentElement;
  const documentRect = html.getBoundingClientRect();
  const { body } = document;
  const screenHeight = window.innerHeight;

  // Only do the magic if document is scrollable
  if (documentRect.height > screenHeight) {
    const cachedScrollPosition =
      -documentRect.top || body.scrollTop || window.scrollY || document.scrollTop || 0;

    html.style.top = coerceCssPixelValue(-cachedScrollPosition);

    html.classList.add(NO_SCROLL_CLASS);

    return () => {
      html.classList.remove(NO_SCROLL_CLASS);

      window.scroll({
        top: cachedScrollPosition,
        behavior: "auto"
      });
    };
  }
};

I got a easy solution which will select from database table and let you do easily.

SELECT b.FirstName + b.LastName FROM tbl_Users b WHERE b.Id='11'

You can easily add a space there if you try

SELECT b.FirstName +' '+ b.LastName FROM Users b WHERE b.Id='23'

Here you can combine as much as your table have.

There are three distinct ways to do this:

1. Negate the exit status with bash (no other answer has said this):

   if ! [ -e "$file" ]; then
       echo "file does not exist"
   fi
   

   Or:

   ! [ -e "$file" ] && echo "file does not exist"
   

2. Negate the test inside the test command [ (that is the way most answers before have presented):

   if [ ! -e "$file" ]; then
       echo "file does not exist"
   fi
   

   Or:

   [ ! -e "$file" ] && echo "file does not exist"
   

3. Act on the result of the test being negative (|| instead of &&):

   Only:

   [ -e "$file" ] || echo "file does not exist"
   

   This looks silly (IMO), don't use it unless your code has to be portable to the Bourne shell (like the /bin/sh of Solaris 10 or earlier) that lacked the pipeline negation operator (!):

   if [ -e "$file" ]; then
       :
   else
       echo "file does not exist"
   fi
   

I'll add a couple of index types

BITMAP - when you have very low number of different possible values, very fast and doesn't take up much space

PARTITIONED - allows the index to be partitioned based on some property usually advantageous on very large database objects for storage or performance reasons.

FUNCTION/EXPRESSION indexes - used to pre-calculate some value based on the table and store it in the index, a very simple example might be an index based on lower() or a substring function.

int total = (int) Math.ceil((double)157/32);

To add to the above answers, ensure you define your function like this:

public function functionName(Request $request)  {
       //
}

Note the "(Request $request)", now set a session like this:

$request->session()->put('key', 'value');

And retrieve the session in this way:

$data = $request->session()->get('key');

To erase the session try this:

$request->session()->forget('key');  

or

$request->session()->flush();

I like Brian Khuu's answer for its simplicity and not needing external packages. I changed it a bit so I'm adding my version here:

import sys
import time


def updt(total, progress):
    """
    Displays or updates a console progress bar.

    Original source: https://stackoverflow.com/a/15860757/1391441
    """
    barLength, status = 20, ""
    progress = float(progress) / float(total)
    if progress >= 1.:
        progress, status = 1, "\r\n"
    block = int(round(barLength * progress))
    text = "\r[{}] {:.0f}% {}".format(
        "#" * block + "-" * (barLength - block), round(progress * 100, 0),
        status)
    sys.stdout.write(text)
    sys.stdout.flush()


runs = 300
for run_num in range(runs):
    time.sleep(.1)
    updt(runs, run_num + 1)

It takes the total number of runs (total) and the number of runs processed so far (progress) assuming total >= progress. The result looks like this:

[#####---------------] 27%

You can give to_s a base other than 10:

10.to_s(16)  #=> "a"

Note that in ruby 2.4 FixNum and BigNum were unified in the Integer class. If you are using an older ruby check the documentation of FixNum#to_s and BigNum#to_s

I just used:

$('#source').prependTo('#destination');

Which I grabbed from here.

There are some problems with 2 dimensional Arrays the way you implement them.

a= [[1,2],[3,4]]
a[0][2]= 5 # works
a[2][0]= 6 # error

Hash as Array

I prefer to use Hashes for multi dimensional Arrays

a= Hash.new
a[[1,2]]= 23
a[[5,6]]= 42

This has the advantage, that you don't have to manually create columns or rows. Inserting into hashes is almost O(1), so there is no drawback here, as long as your Hash does not become too big.

You can even set a default value for all not specified elements

a= Hash.new(0)

So now about how to get subarrays

(3..5).to_a.product([2]).collect { |index| a[index] }
[2].product((3..5).to_a).collect { |index| a[index] }

(a..b).to_a runs in O(n). Retrieving an element from an Hash is almost O(1), so the collect runs in almost O(n). There is no way to make it faster than O(n), as copying n elements always is O(n).

Hashes can have problems when they are getting too big. So I would think twice about implementing a multidimensional Array like this, if I knew my amount of data is getting big.

The 'btoa-atob' module does not export a programmatic interface, it only provides command line utilities.

If you need to convert to Base64 you could do so using Buffer:

console.log(Buffer.from('Hello World!').toString('base64'));

Reverse (assuming the content you're decoding is a utf8 string):

console.log(Buffer.from(b64Encoded, 'base64').toString());

Note: prior to Node v4, use new Buffer rather than Buffer.from.

int main()
{
    int m;
    while(cin>>m)
    {
    }
}

This would read from standard input if it space separated or line separated .

How about:

String.prototype.strcmp = function(s) {
    if (this < s) return -1;
    if (this > s) return 1;
    return 0;
}

Then, to compare s1 with 2:

s1.strcmp(s2)

Use Control.ControlCollection.Find.

TextBox tbx = this.Controls.Find("textBox1", true).FirstOrDefault() as TextBox;
tbx.Text = "found!";

EDIT for asker:

Control[] tbxs = this.Controls.Find(txtbox_and_message[0,0], true);
if (tbxs != null && tbxs.Length > 0)
{
    tbxs[0].Text = "Found!";
}

When you say

foo = 'bar'
baz(foo)

you are not passing foo to the baz function. foo is just a name used to represent a value, in this case 'bar', and that value is passed to the baz function.

• Debug: fine-grained statements concerning program state, typically used for debugging;

• Info: informational statements concerning program state, representing program events or behavior tracking;

• Warn: statements that describe potentially harmful events or states in the program;

• Error: statements that describe non-fatal errors in the application; this level is used quite often for logging handled exceptions;

• Fatal: statements representing the most severe of error conditions, assumedly resulting in program termination.

Those are not files (they don't exist on disk) - they are just names under which some HTTP handlers are registered. Take a look at the web.config in .NET Framework's directory (e.g. C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\web.config):

<configuration>
  <system.web>
    <httpHandlers>
      <add path="eurl.axd" verb="*" type="System.Web.HttpNotFoundHandler" validate="True" />
      <add path="trace.axd" verb="*" type="System.Web.Handlers.TraceHandler" validate="True" />
      <add path="WebResource.axd" verb="GET" type="System.Web.Handlers.AssemblyResourceLoader" validate="True" />
      <add verb="*" path="*_AppService.axd" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="False" />
      <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="False"/>
      <add path="*.axd" verb="*" type="System.Web.HttpNotFoundHandler" validate="True" />
    </httpHandlers>
  </system.web>
<configuration>

You can register your own handlers with a whatever.axd name in your application's web.config. While you can bind your handlers to whatever names you like, .axd has the upside of working on IIS6 out of the box by default (IIS6 passes requests for *.axd to the ASP.NET runtime by default). Using an arbitrary path for the handler, like Document.pdf (or really anything except ASP.NET-specific extensions), requires more configuration work. In IIS7 in integrated pipeline mode this is no longer a problem, as all requests are processed by the ASP.NET stack.

ProgressDialog has become deprecated since API Level 26 https://developer.android.com/reference/android/app/ProgressDialog.html

I include a ProgressBar in my layout

   <ProgressBar
        android:layout_weight="1"
        android:id="@+id/progressBar_cyclic"
        android:visibility="gone"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:minHeight="40dp"
        android:minWidth="40dp" />

and change its visibility to .GONE | .VISIBLE depending on the use case.

    progressBar_cyclic.visibility = View.VISIBLE

I've had a similar issue, and I've resolved it by statically linking libstdc++ into the program I was compiling, like so:

$ LIBS=-lstdc++ ./configure ... etc.

instead of the usual

$ ./configure ... etc.

There might be problems with this solution to do with loading shared libraries at runtime, but I haven't looked into the issue deeply enough to comment.

I was struggling with remote login to MYSQL for my Amazon EC2 Linux instance. Found the solution was to make sure my security group included an inbound rule for MySQL port 3306 to include my IP address (or 0.0.0.0/0 for anywhere). Immediately could connect remotely as soon as I added this rule.

on first button add the following.

onclick="window.location.href='Students.html';"

similarly do the rest 2 buttons.

<input type="button" value="Add Students" onclick="window.location.href='Students.html';"> 
<input type="button" value="Add Courses" onclick="window.location.href='Courses.html';"> 
<input type="button" value="Student Payments" onclick="window.location.href='Payments.html';">

Building from Petesh answer, if only the filename is needed, both path and extension can be stripped in a single line,

filename=$(basename ${fullname%.*})

There is another possible scenario that might get some people as well (if you have python and python3 on your system):

pip3 install boto3

Note the use of pip3 indicates the use of Python 3's pip installation vs just pip which indicates the use of Python 2's.

Assuming you are talking about the ActionEvent class, then there is a big difference between the two methods.

getActionCommand() gives you a String representing the action command. The value is component specific; for a JButton you have the option to set the value with setActionCommand(String command) but for a JTextField if you don't set this, it will automatically give you the value of the text field. According to the javadoc this is for compatability with java.awt.TextField.

getSource() is specified by the EventObject class that ActionEvent is a child of (via java.awt.AWTEvent). This gives you a reference to the object that the event came from.

Edit:

Here is a example. There are two fields, one has an action command explicitly set, the other doesn't. Type some text into each then press enter.

public class Events implements ActionListener {

  private static JFrame frame; 

  public static void main(String[] args) {

    frame = new JFrame("JTextField events");
    frame.getContentPane().setLayout(new FlowLayout());

    JTextField field1 = new JTextField(10);
    field1.addActionListener(new Events());
    frame.getContentPane().add(new JLabel("Field with no action command set"));
    frame.getContentPane().add(field1);

    JTextField field2 = new JTextField(10);
    field2.addActionListener(new Events());
    field2.setActionCommand("my action command");
    frame.getContentPane().add(new JLabel("Field with an action command set"));
    frame.getContentPane().add(field2);


    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setSize(220, 150);
    frame.setResizable(false);
    frame.setVisible(true);
  }

  @Override
  public void actionPerformed(ActionEvent evt) {
    String cmd = evt.getActionCommand();
    JOptionPane.showMessageDialog(frame, "Command: " + cmd);
  }

}

Html.ActionLink generates an <a href=".."></a> tag automatically.

Url.Action generates only an url.

For example:

@Html.ActionLink("link text", "actionName", "controllerName", new { id = "<id>" }, null)

generates:

<a href="/controllerName/actionName/<id>">link text</a>

and

@Url.Action("actionName", "controllerName", new { id = "<id>" }) 

generates:

/controllerName/actionName/<id>

Best plus point which I like is using Url.Action(...)

You are creating anchor tag by your own where you can set your own linked text easily even with some other html tag.

<a href="@Url.Action("actionName", "controllerName", new { id = "<id>" })">

   <img src="<ImageUrl>" style"width:<somewidth>;height:<someheight> />

   @Html.DisplayFor(model => model.<SomeModelField>)
</a>

Or use PyInstaller as an alternative to py2exe. Here is a good starting point. PyInstaller also lets you create executables for linux and mac...

Here is how one could fairly easily use PyInstaller to solve the issue at hand:

pyinstaller oldlogs.py

From the tool's documentation:

PyInstaller analyzes myscript.py and:

• Writes myscript.spec in the same folder as the script.
• Creates a folder build in the same folder as the script if it does not exist.
• Writes some log files and working files in the build folder.
• Creates a folder dist in the same folder as the script if it does not exist.
• Writes the myscript executable folder in the dist folder.

In the dist folder you find the bundled app you distribute to your users.

http://www.gnu.org/software/hello/manual/libc/Variable-Arguments-Output.html gives the following example to print to stderr. You can modify it to use your log function instead:

 #include <stdio.h>
 #include <stdarg.h>

 void
 eprintf (const char *template, ...)
 {
   va_list ap;
   extern char *program_invocation_short_name;

   fprintf (stderr, "%s: ", program_invocation_short_name);
   va_start (ap, template);
   vfprintf (stderr, template, ap);
   va_end (ap);
 }

Instead of vfprintf you will need to use vsprintf where you need to provide an adequate buffer to print into.

A workaround - at least for the minimum size: You can use grid to manage the frames contained in root and make them follow the grid size by setting sticky='nsew'. Then you can use root.grid_rowconfigure and root.grid_columnconfigure to set values for minsize like so:

from tkinter import Frame, Tk

class MyApp():
    def __init__(self):
        self.root = Tk()

        self.my_frame_red = Frame(self.root, bg='red')
        self.my_frame_red.grid(row=0, column=0, sticky='nsew')

        self.my_frame_blue = Frame(self.root, bg='blue')
        self.my_frame_blue.grid(row=0, column=1, sticky='nsew')

        self.root.grid_rowconfigure(0, minsize=200, weight=1)
        self.root.grid_columnconfigure(0, minsize=200, weight=1)
        self.root.grid_columnconfigure(1, weight=1)

        self.root.mainloop()

if __name__ == '__main__':
    app = MyApp()

But as Brian wrote (in 2010 :D) you can still resize the window to be smaller than the frame if you don't limit its minsize.

tightVNC 2.5.X and even pre 2.5 supports multi monitor. When you connect, you get a huge virtual monitor. However, this is also has disadvantages. UltaVNC (Tho when I tried it, was buggy in this area) allows you to connect to one huge virtual monitor or just to 1 screen at a time. (With a button to cycle through them) TightVNC also plan to support such a feature.. (When , no idea) This feature is important as if you have large multi monitors and connecting over a reasonably slow link.. The screen updates are just to slow.. Cutting down to one monitor to focus on is desirable.

I like tightVNC, but UltraVNC seems to have a few more features right now..

I have found tightVNC more solid. And that is why I have stuck with it.

I would try both. They both work well, but I imagine one would suite slightly more then the other.

Excel only shows 255 characters but in fact if more than 255 characters are saved, to see the complete string, consult it in the immediate window

Press Crl + G and type ?RunWhat in the immediate window and press Enter

Simple solution: The sequence is really matter while including the auto complete libraries:

<link href="http://code.jquery.com/ui/1.10.2/themes/smoothness/jquery-ui.css" rel="Stylesheet"></link>
<script src='https://cdn.rawgit.com/pguso/jquery-plugin-circliful/master/js/jquery.circliful.min.js'></script>

From GNU Make error appendix, as you see this is not a Make error but an error coming from gcc.

‘[foo] Error NN’ ‘[foo] signal description’ These errors are not really make errors at all. They mean that a program that make invoked as part of a recipe returned a non-0 error code (‘Error NN’), which make interprets as failure, or it exited in some other abnormal fashion (with a signal of some type). See Errors in Recipes. If no *** is attached to the message, then the subprocess failed but the rule in the makefile was prefixed with the - special character, so make ignored the error.

So in order to attack the problem, the error message from gcc is required. Paste the command in the Makefile directly to the command line and see what gcc says. For more details on Make errors click here.

You can use the free foxit reader to fill in the forms, and if you pay a little you can design the forms that way you want.

You can also us iText to programmaticly create those forms.

There are free online services that allow you to upload a pdf and you can add fields also.

It depends on how you want to do the designing.

EDIT: If you use foxit reader, you can save any form that is fillable.

I'm not sure if this will work for your actual use, but it works in your test case - updated at http://jsfiddle.net/sTD8y/27/ .

I just made it so that the built-in revert is only used if the item has not been dropped before. If it has been dropped, the revert is done manually. You could adjust this to animate to some calculated offset by checking the actual CSS properties, but I'll let you play with that because a lot of it depends on the CSS of the draggable and it's surrounding DOM structure.

$(function() {
    $("#draggable").draggable({
        revert:  function(dropped) {
             var $draggable = $(this),
                 hasBeenDroppedBefore = $draggable.data('hasBeenDropped'),
                 wasJustDropped = dropped && dropped[0].id == "droppable";
             if(wasJustDropped) {
                 // don't revert, it's in the droppable
                 return false;
             } else {
                 if (hasBeenDroppedBefore) {
                     // don't rely on the built in revert, do it yourself
                     $draggable.animate({ top: 0, left: 0 }, 'slow');
                     return false;
                 } else {
                     // just let the built in revert work, although really, you could animate to 0,0 here as well
                     return true;
                 }
             }
        }
    });

    $("#droppable").droppable({
        activeClass: 'ui-state-hover',
        hoverClass: 'ui-state-active',
        drop: function(event, ui) {
            $(this).addClass('ui-state-highlight').find('p').html('Dropped!');
            $(ui.draggable).data('hasBeenDropped', true);
        }
    });
});

This is a pain in VS 2010, here's my workaround solution.

 public string DurationString
        {
            get 
            {
                if (this.Duration.TotalHours < 24)
                    return new DateTime(this.Duration.Ticks).ToString("HH:mm");
                else //If duration is more than 24 hours
                {
                    double totalminutes = this.Duration.TotalMinutes;
                    double hours = totalminutes / 60;
                    double minutes = this.Duration.TotalMinutes - (Math.Floor(hours) * 60);
                    string result = string.Format("{0}:{1}", Math.Floor(hours).ToString("00"), Math.Floor(minutes).ToString("00"));
                    return result;
                }
            } 
        }

Many of the above answers confused me but I suspect it may be due to older versions of Mockito. This answer is accomplished using

• Java 11
• Mockito 3.1.0
• SpringBoot 2.2.7.RELEASE
• JUnit5

Using ArgumentCaptor I have done it this way:

@Mock
MyClientService myClientService;
@InjectMocks 
MyService myService;


@Test
void myTest() {

  ArgumentCaptor<String> captorParam1 = ArgumentCaptor.forClass(String.class);
  ArgumentCaptor<String> captorParam2 = ArgumentCaptor.forClass(String.class);

  Mockito.when(myClientService.doSomething(captorParam1.capture(), captorParam2.capture(), ArgumentMatchers.anyString()))
      .thenReturn(expectedResponse);

  assertDoesNotThrow(() -> myService.process(data));

  assertEquals("param1", captorParam1.getValue());
  assertEquals("param2", captorParam2.getValue());

  verify(myClientService, times(1))
    .doSomething(anyString(), anyString(), anyString());
}

you can use below directive that get a bool value in html input for focus on it...

//js file
angular.module("appName").directive("ngFocus", function () {
       return function (scope, elem, attrs, ctrl) {
             if (attrs.ngFocus === "true") {
                 $(elem).focus();
             }
             if (!ctrl) {
                 return;
             }
       elem.on("focus", function () {
            elem.addClass("has-focus");
            scope.$apply(function () {
                ctrl.hasFocus = true;
            });
        });
    };
});

<!-- html file -->
<input type="text" ng-focus="boolValue" />

You can even set a function in your controller to ngFocus directive value pay attention to below code...

<!-- html file -->
<input type="text" ng-focus="myFunc()" />


//controller file
$scope.myFunc=function(){
      if(condition){
          return true;
      }else{
          return false;
      }
}

this directive to happen when html page render.

Create a Map or a Set, and using "on connection" event set to it each connected socket, in reverse "once disconnect" event delete that socket from the Map we created earlier

import * as Server from 'socket.io';

const io = Server();
io.listen(3000);

const connections = new Set();

io.on('connection', function (s) {

  connections.add(s);

  s.once('disconnect', function () {
    connections.delete(s);
  });

});

Just use myView.setVisibility(View.GONE); to remove it completely. But if you want to reserve the occupied space inside its parent use myView.setVisibility(View.INVISIBLE);

I was looking for the same feature today but couldn't do this in Notepad++. However, we have TextPad to our rescue. It worked for me.

In TextPad's replace dialog, turn on regex; then you could try replacing

<row id="1"/>

by

<row id="\i"/>

Have a look at this link for further amazing replace features of TextPad - http://sublimetext.userecho.com/topic/106519-generate-a-sequence-of-numbers-increment-replace/

Edit: Now compatible with MSVC, C++ and non-GNU compilers (see end).

The question was "most efficient way." The OP doesn't specify platform, he could be compiling for a RISC based ATMEL chip with 256 bytes of flash storage for his code.

For the record, and for those (like me), who appreciate the difference between "the easiest way" and the "most efficient way", and who enjoy learning...

static const long hextable[] = {
   [0 ... 255] = -1, // bit aligned access into this table is considerably
   ['0'] = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, // faster for most modern processors,
   ['A'] = 10, 11, 12, 13, 14, 15,       // for the space conscious, reduce to
   ['a'] = 10, 11, 12, 13, 14, 15        // signed char.
};

/** 
 * @brief convert a hexidecimal string to a signed long

 */
long hexdec(unsigned const char *hex) {
   long ret = 0; 
   while (*hex && ret >= 0) {
      ret = (ret << 4) | hextable[*hex++];
   }
   return ret; 
}

It requires no external libraries, and it should be blindingly fast. It handles uppercase, lowercase, invalid characters, odd-sized hex input (eg: 0xfff), and the maximum size is limited only by the compiler.

For non-GCC or C++ compilers or compilers that will not accept the fancy hextable declaration.

Replace the first statement with this (longer, but more conforming) version:

static const long hextable[] = {

The simplest tutorial for setting up cURL on Windows is the Making cURL work on Windows 7. It only have 3 easy steps.

The method you are trying to call is an instance-level method; you do not have an instance.

static methods belong to the class, non-static methods belong to instances of the class.

As the others stated : it's by compiling. You can use the javac command, but I'f you're new at java, I suggest you use a software for compiling your code (and IDE) such as Eclipse and it will do the job for you.

If you want to create model along with migration use this command:-

sequelize model:create --name regions --attributes name:string,status:boolean --underscored

--underscored it is used to create column having underscore like:- created_at,updated_at or any other column having underscore and support user defined columns having underscore.

The excellent library from @AliSoftware OHAttributedStringAdditions makes it easy to add links in UILabel here is the documentation: https://github.com/AliSoftware/OHAttributedStringAdditions/wiki/link-in-UILabel

A very simple solution using jQuery:

on the client side:

$('.act_download_statement').click(function(e){
    e.preventDefault();
    form = $('#my_form');
    form.submit();
});

and on the server side, make sure you send back the correct Content-Type header, so the browser will know its an attachment and the download will begin.

Don't forget TemplatedParent:

<Binding RelativeSource="{RelativeSource TemplatedParent}"/>

or

{Binding RelativeSource={RelativeSource TemplatedParent}}

The best option is to stage everything but this file, and tell stash to keep the index with git stash save --keep-index, thus stashing your unstaged file:

$ git add .
$ git reset thefiletostash
$ git stash save --keep-index

As Dan points out, thefiletostash is the only one to be reset by the stash, but it also stashes the other files, so it's not exactly what you want.
