Lot of good things have been said above about optimistic and pessimistic locking. One important point to consider is as follows:

When using optimistic locking, we need to cautious of the fact that how will application recover from these failures.

Specially in asynchronous message driven architectures, this can lead of out of order message processing or lost updates.

Failures scenarios need to be thought through.

I had problems with the same error on more than one Spring project. For me a general solution was, to split my service Method, that each INSERT, UPDATE and DELETE action got an own Method with @Transactional. I think this problem relates to the internal Spring managment, where database interactions are executed at the end of the method and, in my oppinion, this is the point, where the Exception is triggered.

You look like you're trying to write C in Python. If you want to find something in a sequence, Python has builtin functions to do that, like

value = sequence.index(blarg)

I was getting this error too. I resolved it by installing: https://git-scm.com/

and running the command from the Git Bash window.

Counting Words in a String:
This might also help -->

package data.structure.test;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class CountWords {

    public static void main(String[] args) throws IOException {
// Couting number of words in a string
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("enter Your String");
        String input = br.readLine(); 

        char[] arr = input.toCharArray();
        int i = 0;
    boolean notCounted = true;
    int counter = 0;
    while (i < arr.length) {
        if (arr[i] != ' ') {
            if (notCounted) {
                notCounted = false;
                counter++;
            }
        } else {
            notCounted = true;
        }
        i++;
    }
    System.out.println("words in the string are : " + counter);
}

}

I just copy pasted the database folders to data folder in MySQL, i.e. If you have a database called alto then find the folder alto in your MySQL -> Data folder in your backup and copy the entire alto folder and past it to newly installed MySQL -> data folder, restart the MySQL and this works perfect.

Demo : http://jsfiddle.net/NbGBj/

$("document").ready(function(){

    $("#upload").change(function() {
        alert('changed!');
    });
});

add #include <iostream> to the start of io.cpp too.

Improving upon @barry-stae's solution. Stick this snippet in ~/.bashrc

function mdviewer(){
  pandoc $* | lynx -stdin
}

Then we can quickly view the file from the command-line. Also works nicely over SSH/Telnet sessions.

OData (Open Data Protocol) is an OASIS standard that defines the best practice for building and consuming RESTful APIs. OData helps you focus on your business logic while building RESTful APIs without having to worry about the approaches to define request and response headers, status codes, HTTP methods, URL conventions, media types, payload formats and query options etc. OData also guides you about tracking changes, defining functions/actions for reusable procedures and sending asynchronous/batch requests etc. Additionally, OData provides facility for extension to fulfil any custom needs of your RESTful APIs.

OData RESTful APIs are easy to consume. The OData metadata, a machine-readable description of the data model of the APIs, enables the creation of powerful generic client proxies and tools. Some of them can help you interact with OData even without knowing anything about the protocol. The following 6 steps demonstrate 6 interesting scenarios of OData consumption across different programming platforms. But if you are a non-developer and would like to simply play with OData, XOData is the best start for you.

One way to get the list of distinct column names from the database is to use distinct() in conjunction with values().

In your case you can do the following to get the names of distinct categories:

q = ProductOrder.objects.values('Category').distinct()
print q.query # See for yourself.

# The query would look something like
# SELECT DISTINCT "app_productorder"."category" FROM "app_productorder"

There are a couple of things to remember here. First, this will return a ValuesQuerySet which behaves differently from a QuerySet. When you access say, the first element of q (above) you'll get a dictionary, NOT an instance of ProductOrder.

Second, it would be a good idea to read the warning note in the docs about using distinct(). The above example will work but all combinations of distinct() and values() may not.

PS: it is a good idea to use lower case names for fields in a model. In your case this would mean rewriting your model as shown below:

class ProductOrder(models.Model):
    product  = models.CharField(max_length=20, primary_key=True)
    category = models.CharField(max_length=30)
    rank = models.IntegerField()

Using str.format:

>>> array_alpha = [ 133, 53, 234, 241 ]
>>> print ''.join('{:02x}'.format(x) for x in array_alpha)
8535eaf1

or using format

>>> print ''.join(format(x, '02x') for x in array_alpha)
8535eaf1

Note: In the format statements, the 02 means it will pad with up to 2 leading 0s if necessary. This is important since [0x1, 0x1, 0x1] i.e. (0x010101) would be formatted to "111" instead of "010101"

or using bytearray with binascii.hexlify:

>>> import binascii
>>> binascii.hexlify(bytearray(array_alpha))
'8535eaf1'

Here is a benchmark of above methods in Python 3.6.1:

from timeit import timeit
import binascii

number = 10000

def using_str_format() -> str:
    return "".join("{:02x}".format(x) for x in test_obj)

def using_format() -> str:
    return "".join(format(x, "02x") for x in test_obj)

def using_hexlify() -> str:
    return binascii.hexlify(bytearray(test_obj)).decode('ascii')

def do_test():
    print("Testing with {}-byte {}:".format(len(test_obj), test_obj.__class__.__name__))
    if using_str_format() != using_format() != using_hexlify():
        raise RuntimeError("Results are not the same")

    print("Using str.format       -> " + str(timeit(using_str_format, number=number)))
    print("Using format           -> " + str(timeit(using_format, number=number)))
    print("Using binascii.hexlify -> " + str(timeit(using_hexlify, number=number)))

test_obj = bytes([i for i in range(255)])
do_test()

test_obj = bytearray([i for i in range(255)])
do_test()

Result:

Testing with 255-byte bytes:
Using str.format       -> 1.459474583090427
Using format           -> 1.5809937679100738
Using binascii.hexlify -> 0.014521426401399307
Testing with 255-byte bytearray:
Using str.format       -> 1.443447684109402
Using format           -> 1.5608712609513171
Using binascii.hexlify -> 0.014114164661833684

Methods using format do provide additional formatting options, as example separating numbers with spaces " ".join, commas ", ".join, upper-case printing "{:02X}".format(x)/format(x, "02X"), etc., but at a cost of great performance impact.

This is an expansion of @Michael Tiller's excellent answer. His answer works for initializing variables from the view by injecting the $attrs object into the controller. The problem occurs if the same controller is called from $routeProvider when you navigate by routing. Then you get injector error Unknown provider : $attrsProvider because $attrs is only available for injection when the view is compiled. The solution is to pass the variable (foo) through $routeParams when initializing controller from route and by $attrs when initializing controller from view. Here's my solution.

From Route

$routeProvider.
        when('/mypage/:foo', {
            templateUrl: 'templates/mypage.html',
            controller: 'MyPageController',
            caseInsensitiveMatch: true,
            resolve: {
                $attrs: function () {
                    return {};
                }
            }
        });

This handles a url such as '/mypage/bar'. As you can see foo is passed by url param and we provide the $injector with a blank object for $attrs so no injector errors.

From View

<div ng-controller="MyPageController" data-foo="bar">

</div>

Now the controller

var app = angular.module('myapp', []);
app.controller('MyPageController',['$scope', '$attrs', '$routeParams'], function($scope, $attrs, $routeParams) {
   //now you can initialize foo. If $attrs contains foo, it's been initialized from view
   //else find it from $routeParams
   var foo = $attrs.foo? $attrs.foo : $routeParams.foo;
   console.log(foo); //prints 'bar'

});

It's same as vikasdumca's steps, but thought to share the link.

run the following command

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update

then

sudo apt-get install oracle-java8-installer

this would install oracle java 8 on ubuntu properly.

find it from this post

you can find more info on "Managing Java" or "Setting the "JAVA_HOME" environment variable" from the post.

For the HTML bellow

<input type="file" id="myFile" />

try the following:

//binds to onchange event of your input field
$('#myFile').bind('change', function() {

  //this.files[0].size gets the size of your file.
  alert(this.files[0].size);

});

See following thread:

How to check file input size with jQuery?

Can't you just try to replace the body content with the document.body handler?

if your page is this:

<html>
<body>
blablabla
<script type="text/javascript">
document.body.innerHTML="hi!";
</script>
</body>
</html>

Just use the document.body to replace the body.

This works for me. All the content of the BODY tag is replaced by the innerHTML you specify. If you need to even change the html tag and all childs you should check out which tags of the 'document.' are capable of doing so.

An example with javascript scripting inside it:

<html>
<body>
blablabla
<script type="text/javascript">
var changeme = "<button onClick=\"document.bgColor = \'#000000\'\">click</button>";
document.body.innerHTML=changeme;
</script>
</body>

This way you can do javascript scripting inside the new content. Don't forget to escape all double and single quotes though, or it won't work. escaping in javascript can be done by traversing your code and putting a backslash in front of all singe and double quotes.

Bare in mind that server side scripting like php doesn't work this way. Since PHP is server-side scripting it has to be processed before a page is loaded. Javascript is a language which works on client-side and thus can not activate the re-processing of php code.

In Eclipse -

1)Checkout master branch

Git Repositories ->Click on your repository -> click on Local ->double click master branch
->Click on yes for check out

2)Pull master branch

Right click on project ->click on Team -> Click on Pull

3)Checkout your feature branch(follow same steps mentioned in 1 point)

4)Merge master into feature

Git Repositories ->Click on your repository -> click on Local ->Right Click on your selected feature branch ->Click on merge ->Click on Local ->Click on Master ->Click on Merge.

5)Now you will get all changes of Master branch in feature branch. Remove conflict if any.

For conflict if any exists ,follow this -
Changes mentioned as Head(<<<<<< HEAD) is your change, Changes mentioned in branch(>>>>>>> branch) is other person change, you can update file accordingly.

Note - You need to do add to index for conflicts files

6)commit and push your changes in feature branch.

Right click on project ->click on Team -> Click on commit -> Commit and Push.

OR

Git Repositories ->Click on your repository -> click on Local ->Right Click on your selected feature branch ->Click on Push Branch ->Preview ->Push

parse and convert it to js object that's it.

success: function(response) {
    var content = "";
    var jsondata = JSON.parse(response);
    for (var x = 0; x < jsonData.length; x++) {
        content += jsondata[x].Id;
        content += "<br>";
        content += jsondata[x].Name;
        content += "<br>";
    }
    $("#ProductList").append(content);
}

The options object can be added to the chart when the new Chart object is created.

var chart1 = new Chart(canvas, {
    type: "pie",
    data: data,
    options: {
         legend: {
            display: false
         },
         tooltips: {
            enabled: false
         }
    }

It looks to me like the background images aren't actually background images...the site has the background images and the quotes in sibling divs with the children of the div containing the images having been assigned position: fixed; The quotes div is also given a transparent background.

wrapper div{
   image wrapper div{
       div for individual image{ <--- Fixed position
          image <--- relative position
       }
   }
   quote wrapper div{
       div for individual quote{
          quote
       }
   }
 }

// use ternary operators
$("#ans").is(':checked') ? 1 : 0;

This isuse because of coflict merge. If you have new commit in origin and not get those files; also you have changed the local master branch files then you got this error. You should fetch again to a new directory and copy your files into that path. Finally, you should commit and push your changes.

I know its old post but still I want to contribute
Above will not work if you have data format like this
'YYYMMDD'

For example:

Dt
20151104

So I tried following in order to get the desired result.

select cast(Left('20151104', 4)||'-'||substring('20151104',5,2)||'-'||substring('20151104', 7,2) as date) from SYSIBM.SYSDUMMY1;

Additionally, If you want to run the query from MS SQL linked server to DB2(To display only 100 rows).

    SELECT top 100 * from OPENQUERY([Linked_Server_Name],
    'select cast(Left(''20151104'', 4)||''-''||substring(''20151104'',5,2)||''-''||substring(''20151104'', 7,2) as date) AS Dt 
    FROM SYSIBM.SYSDUMMY1')

Result after above query:

Dt
2015-11-04

Hope this helps for others.

There are plenty of options. My personal favorite is by KeyValuePair

Dictionary<string, object> myDictionary = new Dictionary<string, object>();
// Populate your dictionary here

foreach (KeyValuePair<string,object> kvp in myDictionary)
{
     // Do some interesting things
}

You can also use the Keys and Values Collections

I recommend you to try Netbeans Profiler.It has rich set of tools for real time analysis. Tools from IbM are worth a try for offline analysis

The code is very long so I can't paste all the code.

There could be any number of reasons why your code doesn't work. Maybe you declared the button variables twice so you aren't actually changing enabling/disabling the button like you think you are. Maybe you are blocking the EDT.

You need to create a SSCCE to post on the forum.

So its up to you to isolate the problem. Start with a simple frame thas two buttons and see if your code works. Once you get that working, then try starting a Thread that simply sleeps for 10 seconds to see if it still works.

Learn how the basice work first before writing a 200 line program.

Learn how to do some basic debugging, we are not mind readers. We can't guess what silly mistake you are doing based on your verbal description of the problem.

In my case, I was able to find the problem by temporarily catching the exception, descending into causes as needed (based on how deep the IllegalAnnotationException was), and calling getErrors() on it.

    try {
        // in my case, this was what gave me an exception
        endpoint.publish("/MyWebServicePort");
    // I got a WebServiceException caused by another exception, which was caused by the IllegalAnnotationsException
    } catch (WebServiceException e) {
        // Incidentally, I need to call getCause().getCause() on it, and cast to IllegalAnnotationsException before calling getErrors()
        System.err.println(((com.sun.xml.internal.bind.v2.runtime.IllegalAnnotationsException)e.getCause().getCause()).getErrors());
    }

+1 to PleaseStand and here is my other hack:

after searching and found that the "cross ajax request" could not get response headers from XHR object, I gave up. and use iframe instead.

1. <iframe style="display:none"></iframe>
2. $("iframe").attr("src", "http://the_url_you_want_to_access")
//this is my aim!!!
3. $("iframe").contents().find('#someID').html()  

CGSize maxSize = CGSizeMake(lbl.frame.size.width, CGFLOAT_MAX);
CGSize requiredSize = [lbl sizeThatFits:maxSize];
CGFloat height=requiredSize.height

clearInterval is one option:

var interval = setInterval(doStuff, 2000); // 2000 ms = start after 2sec 
function doStuff() {
  alert('this is a 2 second warning');
  clearInterval(interval);
}

You can use json_decode(Your variable Name):

json_decode($result)

I was getting value from Model.where a column has value like this way

{"dayList":[
            {"day":[1,2,3,4],"time":[{"in_time":"10:00"},{"late_time":"15:00"},{"out_time":"16:15"}]
             },
             {"day":[5,6,7],"time":[{"in_time":"10:00"},{"late_time":"15:00"},{"out_time":"16:15"}]}
           ]
}

so access this value form model. you have to use this code.

$dayTimeListObject = json_decode($settingAttendance->bio_attendance_day_time,1);

 foreach ( $dayTimeListObject['dayList'] as $dayListArr)
 {
     foreach ( $dayListArr['day'] as $dayIndex)
     {
         if( $dayIndex == Date('w',strtotime('2020-02-11')))
         {
             $dayTimeList= $dayListArr['time'];
         }
     }
 }

 return $dayTimeList[2]['out_time'] ;

You can also define caste in your Model file.

 protected $casts = [
    'your-column-name' => 'json'
  ];

so after this no need of this line .

$dayTimeListObject = json_decode($settingAttendance->bio_attendance_day_time,1);

you can directly access this code.

$settingAttendance->bio_attendance_day_time

In ECMAScript 6 you will actually be able to write exactly what you have:

function read_file(file, delete_after = false) {
  // Code
}

This will set delete_after to false if it s not present or undefined. You can use ES6 features like this one today with transpilers such as Babel.

See the MDN article for more information.

When you are checking if an element has or does not have a class, make sure you didn't accidentally put a dot in the class name:

<div class="className"></div>

$('div').hasClass('className');
$('div').hasClass('.className'); #will not work!!!!

After a long time of staring at my code I realized I had done this. A little typo like this took me an hour to figure out what I had done wrong. Check your code!

Try this way:

echo $( 
    cmd1
    cmd2
    ...
)

Just this 1 line of code changed the background programmatically

tv.setBackgroundColor(Color.parseColor("#808080"));

The solution by Ben Blank wouldn't work in IE8 for me.

However this did work in IE8

function addCss(cssCode) {
var styleElement = document.createElement("style");
  styleElement.type = "text/css";
  if (styleElement.styleSheet) {
    styleElement.styleSheet.cssText = cssCode;
  } else {
    styleElement.appendChild(document.createTextNode(cssCode));
  }
  document.getElementsByTagName("head")[0].appendChild(styleElement);
}

public static JSONObject updateJson(JSONObject obj, String keyString, String newValue) throws Exception {
            JSONObject json = new JSONObject();

            Iterator iterator = obj.keys();
            String key = null;
            while (iterator.hasNext()) {
                key = (String) iterator.next();
                // if the key is a string, then update the value
                if ((obj.optJSONArray(key) == null) && (obj.optJSONObject(key) == null)) {
                    if ((key.equals(keyString))) {
                        // put new value
                        obj.put(key, newValue);
                        return obj;
                    }
                }

                // if it's jsonobject
                if (obj.optJSONObject(key) != null) {
                    updateJson(obj.getJSONObject(key), keyString, newValue);
                }

                // if it's jsonarray
                if (obj.optJSONArray(key) != null) {
                    JSONArray jArray = obj.getJSONArray(key);
                    for (int i = 0; i < jArray.length(); i++) {
                        updateJson(jArray.getJSONObject(i), keyString, newValue);
                    }
                }
            }
            return obj;
        }

Generally speaking, it's recommended to use MSI-based installations on Windows. Thus, if you're ready to invest a fair bit of time, WiX is the way to go.

If you want something which is much more simpler, go with InnoSetup.

I'm not sure what you mean by a string that contains binary numbers. But for reversing a string (or any STL-compatible container), you can use std::reverse(). std::reverse() operates in place, so you may want to make a copy of the string first:

#include <algorithm>
#include <iostream>
#include <string>

int main()
{
    std::string foo("foo");
    std::string copy(foo);
    std::cout << foo << '\n' << copy << '\n';

    std::reverse(copy.begin(), copy.end());
    std::cout << foo << '\n' << copy << '\n';
}

just for fun...

$array_a = array('0'=>'foo', '1'=>'bar');
$array_b = array('foo'=>'0', 'bar'=>'1');

$array_c = array_merge($array_a,$array_b);

$i = 0; $j = 0;
foreach ($array_c as $key => $value) {
    if (is_numeric($key)) {$array_d[$i] = $value; $i++;}
    if (is_numeric($value)) {$array_e[$j] = $key; $j++;}
}

print_r($array_d);
print_r($array_e);

If you are using C99 just include stdint.h. BTW, the 64bit types are there iff the processor supports them.

If you are using T-SQL you could use a temporary table in a stored procedure and update or insert the records of your query accordingly.

You can use peek to do that.

List<Fruit> newList = fruits.stream()
    .peek(f -> f.setName(f.getName() + "s"))
    .collect(Collectors.toList());

You could just use the bound ng-model (answers[item.questID]) value itself in your ng-change method to detect if it has been checked or not.

Example:-

<input type="checkbox" ng-model="answers[item.questID]" 
     ng-change="stateChanged(item.questID)" /> <!-- Pass the specific id -->

and

$scope.stateChanged = function (qId) {
   if($scope.answers[qId]){ //If it is checked
       alert('test');
   }
}

Type history in your terminal. It's not technically git, but I think it is what you want.

I think you could set the headers and still use getJSON() like this:

$.ajaxSetup({
  headers : {
    'Authorization' : 'Basic faskd52352rwfsdfs',
    'X-PartnerKey' : '3252352-sdgds-sdgd-dsgs-sgs332fs3f'
  }
});
$.getJSON('http://localhost:437/service.svc/logins/jeffrey/house/fas6347/devices?format=json', function(json) { alert("Success"); }); 

blog_development doesn't exist

You can see this in sql by the 0 rows affected message

create it in mysql with

mysql> create database blog_development

However as you are using rails you should get used to using

$ rake db:create

to do the same task. It will use your database.yml file settings, which should include something like:

development:
  adapter: mysql2
  database: blog_development
  pool: 5

Also become familiar with:

$ rake db:migrate  # Run the database migration
$ rake db:seed     # Run thew seeds file create statements
$ rake db:drop     # Drop the database

        }
        clazz = clazz.getSuperclass();
    }
    return result.toArray(new Method[result.size()]);
}

In my case, I still wanted the open on odd pages option but this would produce a blank page with the chapter name in the header. I didn't want the header. And so to avoid this I used this at the end of the chapter:

\clearpage

\thispagestyle{plain}

This let's you keep the blank page on the last even page of the chapter but without the header.

You can also set the title of your chart by adding the title parameter as follows

ax.set(xlabel='common xlabel', ylabel='common ylabel', title='some title')

Setting \itemindent for a new itemize environment solves the problem:

\newenvironment{beameritemize}
{ \begin{itemize}
  \setlength{\itemsep}{1.5ex}
  \setlength{\parskip}{0pt}
  \setlength{\parsep}{0pt}   
  \addtolength{\itemindent}{-2em}  }
{ \end{itemize} } 

Test its side-effects. This includes:

• Does it throw any exceptions? (If it should, check that it does. If it shouldn't, try some corner cases which might if you're not careful - null arguments being the most obvious thing.)
• Does it play nicely with its parameters? (If they're mutable, does it mutate them when it shouldn't and vice versa?)
• Does it have the right effect on the state of the object/type you're calling it on?

Of course, there's a limit to how much you can test. You generally can't test with every possible input, for example. Test pragmatically - enough to give you confidence that your code is designed appropriately and implemented correctly, and enough to act as supplemental documentation for what a caller might expect.

A straight forward way would be :

soup = BeautifulSoup(sdata)
for each_div in soup.findAll('div',{'class':'stylelist'}):
    print each_div

Make sure you take of the casing of findAll, its not findall

The ? operand makes match non-greedy. E.g. .* is greedy while .*? isn't. So you can use something like <img.*?> to match the whole tag. Or <img[^>]*>.

But remember that the whole set of HTML can't be actually parsed with regular expressions.

small correction on @PetrosTsialiamanis post , new File( multipart.getOriginalFilename()) this will create file in server location where sometime you will face write permission issues for the user, its not always possible to give write permission to every user who perform action. System.getProperty("java.io.tmpdir") will create temp directory where your file will be created properly. This way you are creating temp folder, where file gets created , later on you can delete file or temp folder.

public  static File multipartToFile(MultipartFile multipart, String fileName) throws IllegalStateException, IOException {
    File convFile = new File(System.getProperty("java.io.tmpdir")+"/"+fileName);
    multipart.transferTo(convFile);
    return convFile;
}

put this method in ur common utility and use it like for eg. Utility.multipartToFile(...)

I had some issues importing additional libraries, after trying to resolve the problem, by understanding PYTHONPATH, Interpreter, and Grammar I found that I did everything write but the problems continue. After that, I just add a new empty line in the files that had the import errors and saved them and the error was resolved.

Try this,

// prepare json data
let json: [String: Any] = ["title": "ABC",
                           "dict": ["1":"First", "2":"Second"]]

let jsonData = try? JSONSerialization.data(withJSONObject: json)

// create post request
let url = URL(string: "http://httpbin.org/post")!
var request = URLRequest(url: url)
request.httpMethod = "POST"

// insert json data to the request
request.httpBody = jsonData

let task = URLSession.shared.dataTask(with: request) { data, response, error in
    guard let data = data, error == nil else {
        print(error?.localizedDescription ?? "No data")
        return
    }
    let responseJSON = try? JSONSerialization.jsonObject(with: data, options: [])
    if let responseJSON = responseJSON as? [String: Any] {
        print(responseJSON)
    }
}

task.resume()

or try a convenient way Alamofire

You can use find_all in the following way to find every a element that has an href attribute, and print each one:

from BeautifulSoup import BeautifulSoup

html = '''<a href="some_url">next</a>
<span class="class"><a href="another_url">later</a></span>'''

soup = BeautifulSoup(html)

for a in soup.find_all('a', href=True):
    print "Found the URL:", a['href']

The output would be:

Found the URL: some_url
Found the URL: another_url

Note that if you're using an older version of BeautifulSoup (before version 4) the name of this method is findAll. In version 4, BeautifulSoup's method names were changed to be PEP 8 compliant, so you should use find_all instead.

If you want all tags with an href, you can omit the name parameter:

href_tags = soup.find_all(href=True)

I just built a few TimeSpan Extension methods. Thought I could share:

public static string ToReadableAgeString(this TimeSpan span)
{
    return string.Format("{0:0}", span.Days / 365.25);
}

public static string ToReadableString(this TimeSpan span)
{
    string formatted = string.Format("{0}{1}{2}{3}",
        span.Duration().Days > 0 ? string.Format("{0:0} day{1}, ", span.Days, span.Days == 1 ? string.Empty : "s") : string.Empty,
        span.Duration().Hours > 0 ? string.Format("{0:0} hour{1}, ", span.Hours, span.Hours == 1 ? string.Empty : "s") : string.Empty,
        span.Duration().Minutes > 0 ? string.Format("{0:0} minute{1}, ", span.Minutes, span.Minutes == 1 ? string.Empty : "s") : string.Empty,
        span.Duration().Seconds > 0 ? string.Format("{0:0} second{1}", span.Seconds, span.Seconds == 1 ? string.Empty : "s") : string.Empty);

    if (formatted.EndsWith(", ")) formatted = formatted.Substring(0, formatted.Length - 2);

    if (string.IsNullOrEmpty(formatted)) formatted = "0 seconds";

    return formatted;
}

var redBox = $(".post");

var greenBox = $(".post1");

var offset = redBox.offset();

$(".post1").css({'left': +offset.left});
$(".post1").html("Left :" +offset.left);

Here is what I ended up doing to work around the error.

First, I set up the database recovery model as SIMPLE. More information here.

Then, by deleting some old files I was able to make 5GB of free space which gave the log file more space to grow.

I reran the DELETE statement sucessfully without any warning.

I thought that by running the DELETE statement the database would inmediately become smaller thus freeing space in my hard drive. But that was not true. The space freed after a DELETE statement is not returned to the operating system inmediatedly unless you run the following command:

DBCC SHRINKDATABASE (MyDb, 0);
GO

More information about that command here.

I used the second solution of user147767

However, there is a typo here. It should be

curCssName.toUpperCase().indexOf(cssName.toUpperCase() + ':') < 0

not <= 0

I also changed this condition for:

!curCssName.match(new RegExp(cssName + "(-.+)?:"), "mi")

as sometimes we add a css property over jQuery, and it's added in a different way for different browsers (i.e. the border property will be added as "border" for Firefox, and "border-top", "border-bottom" etc for IE).

Using case

#!/bin/bash

fun1 () {
    echo "run function1"
    [[ "$@" ]] && echo "options: $@"
}

fun2 () {
    echo "run function2"
    [[ "$@" ]] && echo "options: $@"
}

case $1 in
    fun1) "$@"; exit;;
    fun2) "$@"; exit;;
esac

fun1
fun2

This script will run functions fun1 and fun2 but if you start it with option fun1 or fun2 it'll only run given function with args(if provided) and exit. Usage

$ ./test 
run function1
run function2

$ ./test fun2 a b c
run function2
options: a b c

Performance

Today 2020.06.20 I perform test on MacOs High Sierra on Chrome 81.0, Firefox 77.0 and Safari 13.1 for chosen solutions.

Conclusions for solutions which use precalculations

Solutions with precalculations (K,L) are (much much) faster than other solutions and will not be compared with them - probably they are use some special build-in browser optimisations

• surprisingly on Chrome and Safari solution based on Map (K) are much faster than solution based on object {} (L)
• surprisingly on Safari for small arrays solution based on object {} (L) is slower than traditional for (E)
• surprisingly on Firefox for small arrays solution based on Map (K) is slower than traditional for (E)

Conclusions when searched objects ALWAYS exists

• solution which use traditional for (E) is fastest for small arrays and fast for big arrays
• solution using cache (J) is fastest for big arrays - surprisingly for small arrays is medium fast
• solutions based on find (A) and findIndex (B) are fast for small arras and medium fast on big arrays
• solution based on $.map (H) is slowest on small arrays
• solution based on reduce (D) is slowest on big arrays

Conclusions when searched objects NEVER exists

• solution based on traditional for (E) is fastest on small and big arrays (except Chrome-small arrays where it is second fast)
• solution based on reduce (D) is slowest on big arrays
• solution which use cache (J) is medium fast but can be speed up if we save in cache also keys which have null values (which was not done here because we want to avoid unlimited memory consumption in cache in case when many not existing keys will be searched)

Details

For solutions

• without precalculations: A B C D E F G H I J (the J solution use 'inner' cache and it speed depend on how often searched elements will repeat)
• with precalculations K L

I perform four tests. In tests I want to find 5 objects in 10 loop iterations (the objects ID not change during iterations) - so I call tested method 50 times but only first 5 times have unique id values:

• small array (10 elements) and searched object ALWAYS exists - you can perform it HERE
• big array (10k elements) and searched object ALWAYS exist - you can perform it HERE
• small array (10 elements) and searched object NEVER exists - you can perform it HERE
• big array (10k elements) and searched object NEVER exists - you can perform it HERE

Tested codes are presented below

function A(arr, id) {
  return arr.find(o=> o.id==id);
}

function B(arr, id) {
  let idx= arr.findIndex(o=> o.id==id);
  return arr[idx];
}

function C(arr, id) {
  return arr.filter(o=> o.id==id)[0];
}

function D(arr, id) {
  return arr.reduce((a, b) => (a.id==id && a) || (b.id == id && b));
}

function E(arr, id) {
  for (var i = 0; i < arr.length; i++) if (arr[i].id==id) return arr[i];
  return null;
}

function F(arr, id) {
  var retObj ={};
  $.each(arr, (index, obj) => {
    if (obj.id == id) { 
      retObj = obj;
      return false;
    }
  });
  return retObj;
}

function G(arr, id) {
  return $.grep(arr, e=> e.id == id )[0];
}

function H(arr, id) {
  return $.map(myArray, function(val) {
    return val.id == id ? val : null;
  })[0];
}

function I(arr, id) {
  return _.find(arr, o => o.id==id);
}

let J = (()=>{
  let cache = new Map();
  return function J(arr,id,el=null) { 
    return cache.get(id) || (el=arr.find(o=> o.id==id), cache.set(id,el), el);
  }
})();

function K(arr, id) {
  return mapK.get(id)
}

function L(arr, id) {
  return mapL[id];
}



// -------------

console.log('Find id=5');

myArray = [...Array(10)].map((x,i)=> ({'id':`${i}`, 'foo':`bar_${i}`}));
const mapK = new Map( myArray.map(el => [el.id, el]) );
const mapL = {}; myArray.forEach(el => mapL[el.id]=el);



[A,B,C,D,E,F,G,H,I,J,K,L].forEach(f=> console.log(`${f.name}: ${JSON.stringify(f(myArray, '5'))}`));

Wanna a list of folder in xampp?

Just delete or change the file index.php to index.txt. And you will get the list just typing url: localhost.

In PHP 5+ objects are passed by reference. In PHP 4 they are passed by value (that's why it had runtime pass by reference, which became deprecated).

You can use the 'clone' operator in PHP5 to copy objects:

$objectB = clone $objectA;

Also, it's just objects that are passed by reference, not everything as you've said in your question...

Stored procedure:

• Is like a miniature program in SQL Server.
• Can be as simple as a select statement, or as complex as a long script that adds, deletes, updates, and/or reads data from multiple tables in a database.
• (Can implement loops and cursors, which both allow you to work with smaller results or row by row operations on data.)
• Should be called using EXEC or EXECUTE statement.
• Returns table variables, but we can't use OUT parameter.
• Supports transactions.

Function:

• Can not be used to update, delete, or add records to the database.
• Simply returns a single value or a table value.

• Can only be used to select records. However, it can be called very easily from within standard SQL, such as:

  SELECT dbo.functionname('Parameter1')
  

  or

  SELECT Name, dbo.Functionname('Parameter1') FROM sysObjects
  

• For simple reusable select operations, functions can simplify code. Just be wary of using JOIN clauses in your functions. If your function has a JOIN clause and you call it from another select statement that returns multiple results, that function call will JOIN those tables together for each line returned in the result set. So though they can be helpful in simplifying some logic, they can also be a performance bottleneck if they're not used properly.

• Returns the values using OUT parameter.
• Does not support transactions.

Here's a function:

clear <- function() cat(c("\033[2J","\033[0;0H"))

then you can simply call it, as you call any other R function, clear().

If you prefer to simply type clear (instead of having to type clear(), i.e. with the parentheses), then you can do

clear_fun <- function() cat(c("\033[2J","\033[0;0H"));
makeActiveBinding("clear", clear_fun, baseenv())

you have defined the public dir in app root/public

app.use(express.static(__dirname + '/public')); 

so you have to use:

./css/main.css

Solution:
Instead of using setHeader method I have used addHeader.

response.addHeader("Access-Control-Allow-Origin", "*");

* in above line will allow access to all domains, For allowing access to specific domain only:

response.addHeader("Access-Control-Allow-Origin", "http://www.example.com");

I found the answer:

$mail->AddEmbeddedImage('img/2u_cs_mini.jpg', 'logo_2u');

and on the <img> tag put src='cid:logo_2u'

You could use a @HostListener decorator. Works with Angular 4 and up.

import { HostListener } from '@angular/core';

@HostListener("window:scroll", []) onWindowScroll() {
    // do some stuff here when the window is scrolled
    const verticalOffset = window.pageYOffset 
          || document.documentElement.scrollTop 
          || document.body.scrollTop || 0;
}

The problem lies with the syntax definition, try using ruler and compasses for a more classical description!

Cheers,

SimpleDateFormat("MM-dd-yyyy");

instead of

SimpleDateFormat("mm-dd-yyyy");

because MM points Month, mm points minutes

SimpleDateFormat sm = new SimpleDateFormat("MM-dd-yyyy");
String strDate = sm.format(myDate);

Following worked for me:

1. Uninstall the previously installed ‘Microsoft Online Service Sign-in Assistant’ and ‘Windows Azure Active Directory Module for Windows PowerShell’.
2. Install 64-bit versions of ‘Microsoft Online Service Sign-in Assistant’ and ‘Windows Azure Active Directory Module for Windows PowerShell’. https://littletalk.wordpress.com/2013/09/23/install-and-configure-the-office-365-powershell-cmdlets/

If you get the following error In order to install Windows Azure Active Directory Module for Windows PowerShell, you must have Microsoft Online Services Sign-In Assistant version 7.0 or greater installed on this computer, then install the Microsoft Online Services Sign-In Assistant for IT Professionals BETA: http://www.microsoft.com/en-us/download/details.aspx?id=39267

3. Copy the folders called MSOnline and MSOnline Extended from the source

C:\Windows\System32\WindowsPowerShell\v1.0\Modules\

to the folder

C:\Windows\SysWOW64\WindowsPowerShell\v1.0\Modules\

https://stackoverflow.com/a/16018733/5810078.

(But I have actually copied all the possible files from

C:\Windows\System32\WindowsPowerShell\v1.0\

to

C:\Windows\SysWOW64\WindowsPowerShell\v1.0\

(For copying you need to alter the security permissions of that folder))

function formatNumberCapture () {
$('#input_id').on('keyup', function () {
    $(this).val(function(index, value) {
        return value
            .replace(/\D/g, "")
            .replace(/\B(?=(\d{3})+(?!\d))/g, ",")
            ;
    });
});

You can try this, it works for me

To prevent division by zero you could pre-initialize the output 'out' where the div0 error happens, eg np.where does not cut it since the complete line is evaluated regardless of condition.

example with pre-initialization:

a = np.arange(10).reshape(2,5)
a[1,3] = 0
print(a)    #[[0 1 2 3 4], [5 6 7 0 9]]
a[0]/a[1]   # errors at 3/0
out = np.ones( (5) )  #preinit
np.divide(a[0],a[1], out=out, where=a[1]!=0) #only divide nonzeros else 1

maybe for someone it will be useful

for Postgresql 9.5 works as a charm

INSERT INTO tabelname(id, col2, col3, col4)
VALUES
    (1, 1, 1, 'text for col4'),
    (DEFAULT,1,4,'another text for col4')
ON CONFLICT (id) DO UPDATE SET
    col2 = EXCLUDED.col2,
    col3 = EXCLUDED.col3,
    col4 = EXCLUDED.col4

this SQL updates existing record and inserts if new one (2 in 1)

I like to go with easy process. First Change string into Array for easy iterating, then using map function change each word as you want it to be.

function capitalizeCase(str) {
    var arr = str.split(' ');
    var t;
    var newt;
    var newarr = arr.map(function(d){
        t = d.split('');
        newt = t.map(function(d, i){
                  if(i === 0) {
                     return d.toUpperCase();
                    }
                 return d.toLowerCase();
               });
        return newt.join('');
      });
    var s = newarr.join(' ');
    return s;
  }

Perhaps not in the context that you have it, but you could use

SELECT DISTINCT col1,
PERCENTILE_CONT(col2) WITHIN GROUP (ORDER BY col2) OVER (PARTITION BY col1),
PERCENTILE_CONT(col2) WITHIN GROUP (ORDER BY col2) OVER (PARTITION BY col1, col3),
FROM TableA

You would use this to return different levels of aggregation returned in a single row. The use case would be for when a single grouping would not suffice all of the aggregates needed.

Q&A Style

Well, after researching and fighting with the problem for hours, I found out that there are two ways to accomplish this, depending on the structure of your table and if you have foreign keys restrictions activated to maintain integrity. I'd like to share this in a clean format to save some time to the people that may be in my situation.

Option 1: You can afford deleting the row

In other words, you don't have foreign key, or if you have them, your SQLite engine is configured so that there no are integrity exceptions. The way to go is INSERT OR REPLACE. If you are trying to insert/update a player whose ID already exists, the SQLite engine will delete that row and insert the data you are providing. Now the question comes: what to do to keep the old ID associated?

Let's say we want to UPSERT with the data user_name='steven' and age=32.

Look at this code:

INSERT INTO players (id, name, age)

VALUES (
    coalesce((select id from players where user_name='steven'),
             (select max(id) from drawings) + 1),
    32)

The trick is in coalesce. It returns the id of the user 'steven' if any, and otherwise, it returns a new fresh id.

Option 2: You cannot afford deleting the row

After monkeying around with the previous solution, I realized that in my case that could end up destroying data, since this ID works as a foreign key for other table. Besides, I created the table with the clause ON DELETE CASCADE, which would mean that it'd delete data silently. Dangerous.

So, I first thought of a IF clause, but SQLite only has CASE. And this CASE can't be used (or at least I did not manage it) to perform one UPDATE query if EXISTS(select id from players where user_name='steven'), and INSERT if it didn't. No go.

And then, finally I used the brute force, with success. The logic is, for each UPSERT that you want to perform, first execute a INSERT OR IGNORE to make sure there is a row with our user, and then execute an UPDATE query with exactly the same data you tried to insert.

Same data as before: user_name='steven' and age=32.

-- make sure it exists
INSERT OR IGNORE INTO players (user_name, age) VALUES ('steven', 32); 

-- make sure it has the right data
UPDATE players SET user_name='steven', age=32 WHERE user_name='steven'; 

And that's all!

EDIT

As Andy has commented, trying to insert first and then update may lead to firing triggers more often than expected. This is not in my opinion a data safety issue, but it is true that firing unnecessary events makes little sense. Therefore, a improved solution would be:

-- Try to update any existing row
UPDATE players SET age=32 WHERE user_name='steven';

-- Make sure it exists
INSERT OR IGNORE INTO players (user_name, age) VALUES ('steven', 32); 

Complementing the @djechlin answer (good answer by the way!), this function call could be also used as dummy code to hold a breakpoint in an IDE when you want to stop in some specific iteration or a particular recursive call, for example:

isUserAGoat() could be used instead of a dummy variable declaration that will be shown in the IDE as a warning and, in Eclipse particular case, will clog the breakpoint mark, making it difficult to enable/disable it. If the method is used as a convention, all the invocations could be later filtered by some script (during commit phase maybe?).

Google guys are heavy Eclipse users (they provide several of their projects as Eclipse plugins: Android SDK, GAE, etc), so the @djechlin answer and this complementary answer make a lot of sense (at least for me).

You need to use following construction

InputStream in = getClass().getResourceAsStream("/yourFile");

Please note that you have to add this slash before your file name.

ALTER TABLE table_name
MODIFY (column_name data_type);

To check if a string variable contains a valid email address, the easiest way is to test it against a regular expression. There is a good discussion of various regex's and their trade-offs at regular-expressions.info.

Here is a relatively simple one that leans on the side of allowing some invalid addresses through: ^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,6}$

How you can use regular expressions depends on the version of iOS you are using.

iOS 4.x and Later

You can use NSRegularExpression, which allows you to compile and test against a regular expression directly.

iOS 3.x

Does not include the NSRegularExpression class, but does include NSPredicate, which can match against regular expressions.

NSString *emailRegex = ...;
NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
BOOL isValid = [emailTest evaluateWithObject:checkString];

Read a full article about this approach at cocoawithlove.com.

iOS 2.x

Does not include any regular expression matching in the Cocoa libraries. However, you can easily include RegexKit Lite in your project, which gives you access to the C-level regex APIs included on iOS 2.0.

In swift:

   if self.mainScroll.contentSize.height > self.mainScroll.bounds.size.height {
        let bottomOffset = CGPointMake(0, self.mainScroll.contentSize.height - self.mainScroll.bounds.size.height);
        self.mainScroll.setContentOffset(bottomOffset, animated: true)
    }

With Java 8, you can do this:

int[] haystack = {1, 2, 3};
int needle = 3;

boolean found = Arrays.stream(haystack).anyMatch(x -> x == needle);

You'd need to do

boolean found = Arrays.stream(haystack).anyMatch(x -> needle.equals(x));

if you're working with objects.

To expand on @PhiLho answer, you can center a very large image (or any size image) on a page with:

{ 
background-image: url(_images/home.jpg);
background-repeat:no-repeat;
background-position:center; 
}

Or you could use a smaller image with a background color that matches the background of the image (if it is a solid color). This may or may not suit your purposes.

{ 
background-color: green;
background-image: url(_images/home.jpg);
background-repeat:no-repeat;
background-position:center; 
}

It is mostly used for importing symbols from / exporting symbols to a shared library (DLL). Both Visual C++ and GCC compilers support __declspec(dllimport) and __declspec(dllexport). Other uses (some Microsoft-only) are documented in the MSDN.

Get a date object from the jquery date picker using

var myDate = $('element').datepicker('getDate')

For mysql the date needs to be in the proper format. One option which handles any timezone issues is to use moment.js

moment(myDate).format('YYYY-MM-DD HH:mm:ss')

One simple but elegant way is to create a config.php file (or whatever you call it) that just returns an array:

<?php

return array(
    'host' => 'localhost',
    'username' => 'root',
);

And then:

$configs = include('config.php');

With json-loader installed, now you can simply use:

import suburbs from '../suburbs.json';

or, even more simply:

import suburbs from '../suburbs';

In a project of mine I wrap Text instances around Containers. This particular code sample features two stacked Text objects.

Here's a code sample.

    //80% of screen width
    double c_width = MediaQuery.of(context).size.width*0.8;

    return new Container (
      padding: const EdgeInsets.all(16.0),
      width: c_width,
      child: new Column (
        children: <Widget>[
          new Text ("Long text 1 Long text 1 Long text 1 Long text 1 Long text 1 Long text 1 Long text 1 Long text 1 Long text 1 Long text 1 Long text 1 Long text 1 Long text 1 Long text 1 ", textAlign: TextAlign.left),
          new Text ("Long Text 2, Long Text 2, Long Text 2, Long Text 2, Long Text 2, Long Text 2, Long Text 2, Long Text 2, Long Text 2, Long Text 2, Long Text 2", textAlign: TextAlign.left),
        ],
      ),
    );

[edit] Added a width constraint to the container

Use worksheet.find (worksheet is your worksheet) and use the row-range for its range-object. You can get the rangeobject like: worksheet.rows(rowIndex) as example

Then give find the required parameters it should find it for you fine. If I recall correctly, find returns the first match per default. I have no Excel at hand, so you have to look up find for yourself, sorry

I would advise against using a for-loop it is more fragile and ages slower than find.

DateTimeOffset is a representation of instantaneous time (also known as absolute time). By that, I mean a moment in time that is universal for everyone (not accounting for leap seconds, or the relativistic effects of time dilation). Another way to represent instantaneous time is with a DateTime where .Kind is DateTimeKind.Utc.

This is distinct from calendar time (also known as civil time), which is a position on someone's calendar, and there are many different calendars all over the globe. We call these calendars time zones. Calendar time is represented by a DateTime where .Kind is DateTimeKind.Unspecified, or DateTimeKind.Local. And .Local is only meaningful in scenarios where you have an implied understanding of where the computer that is using the result is positioned. (For example, a user's workstation)

So then, why DateTimeOffset instead of a UTC DateTime? It's all about perspective. Let's use an analogy - we'll pretend to be photographers.

Imagine you are standing on a calendar timeline, pointing a camera at a person on the instantaneous timeline laid out in front of you. You line up your camera according to the rules of your timezone - which change periodically due to daylight saving time, or due to other changes to the legal definition of your time zone. (You don't have a steady hand, so your camera is shaky.)

The person standing in the photo would see the angle at which your camera came from. If others were taking pictures, they could be from different angles. This is what the Offset part of the DateTimeOffset represents.

So if you label your camera "Eastern Time", sometimes you are pointing from -5, and sometimes you are pointing from -4. There are cameras all over the world, all labeled different things, and all pointing at the same instantaneous timeline from different angles. Some of them are right next to (or on top of) each other, so just knowing the offset isn't enough to determine which timezone the time is related to.

And what about UTC? Well, it's the one camera out there that is guaranteed to have a steady hand. It's on a tripod, firmly anchored into the ground. It's not going anywhere. We call its angle of perspective the zero offset.

So - what does this analogy tell us? It provides some intuitive guidelines-

• If you are representing time relative to some place in particular, represent it in calendar time with a DateTime. Just be sure you don't ever confuse one calendar with another. Unspecified should be your assumption. Local is only useful coming from DateTime.Now. For example, I might get DateTime.Now and save it in a database - but when I retrieve it, I have to assume that it is Unspecified. I can't rely that my local calendar is the same calendar that it was originally taken from.

• If you must always be certain of the moment, make sure you are representing instantaneous time. Use DateTimeOffset to enforce it, or use UTC DateTime by convention.

• If you need to track a moment of instantaneous time, but you want to also know "What time did the user think it was on their local calendar?" - then you must use a DateTimeOffset. This is very important for timekeeping systems, for example - both for technical and legal concerns.

• If you ever need to modify a previously recorded DateTimeOffset - you don't have enough information in the offset alone to ensure that the new offset is still relevant for the user. You must also store a timezone identifier (think - I need the name of that camera so I can take a new picture even if the position has changed).

  It should also be pointed out that Noda Time has a representation called ZonedDateTime for this, while the .Net base class library does not have anything similar. You would need to store both a DateTimeOffset and a TimeZoneInfo.Id value.

• Occasionally, you will want to represent a calendar time that is local to "whomever is looking at it". For example, when defining what today means. Today is always midnight to midnight, but these represent a near-infinite number of overlapping ranges on the instantaneous timeline. (In practice we have a finite number of timezones, but you can express offsets down to the tick) So in these situations, make sure you understand how to either limit the "who's asking?" question down to a single time zone, or deal with translating them back to instantaneous time as appropriate.

Here are a few other little bits about DateTimeOffset that back up this analogy, and some tips for keeping it straight:

• If you compare two DateTimeOffset values, they are first normalized to zero offset before comparing. In other words, 2012-01-01T00:00:00+00:00 and 2012-01-01T02:00:00+02:00 refer to the same instantaneous moment, and are therefore equivalent.

• If you are doing any unit testing and need to be certain of the offset, test both the DateTimeOffset value, and the .Offset property separately.

• There is a one-way implicit conversion built in to the .Net framework that lets you pass a DateTime into any DateTimeOffset parameter or variable. When doing so, the .Kind matters. If you pass a UTC kind, it will carry in with a zero offset, but if you pass either .Local or .Unspecified, it will assume to be local. The framework is basically saying, "Well, you asked me to convert calendar time to instantaneous time, but I have no idea where this came from, so I'm just going to use the local calendar." This is a huge gotcha if you load up an unspecified DateTime on a computer with a different timezone. (IMHO - that should throw an exception - but it doesn't.)

Shameless Plug:

Many people have shared with me that they find this analogy extremely valuable, so I included it in my Pluralsight course, Date and Time Fundamentals. You'll find a step-by-step walkthrough of the camera analogy in the second module, "Context Matters", in the clip titled "Calendar Time vs. Instantaneous Time".

To me a simple

sudo apt-get update

solved the issue. It was a clock issue and with this command it resets to the current date/time and everything worked

sudo nginx -t should test all files and return errors and warnings locations

If you are parsing string data from the console or similar, the best way is to use regular expressions. Read more on that here: http://java.sun.com/developer/technicalArticles/releases/1.4regex/

Otherwise, to parse an int from a string, try Integer.parseInt(string). If the string is not a number, you will get an exception. Otherise you can then perform your checks on that value to make sure it is not negative.

String input;
int number;
try
{
    number = Integer.parseInt(input);
    if(number > 0)
    {
        System.out.println("You positive number is " + number);
    }
} catch (NumberFormatException ex)
{
     System.out.println("That is not a positive number!");
}

To get a character-only string, you would probably be better of looping over each character checking for digits, using for instance Character.isLetter(char).

String input
for(int i = 0; i<input.length(); i++)
{
   if(!Character.isLetter(input.charAt(i)))
   {
      System.out.println("This string does not contain only letters!");
      break;
   }
}

Good luck!

System.out.println(Arrays.toString(arr));

It's for validation purposes.

Validation It is common to validate a model after binding user input to it. Spring 3 provides support for declarative validation with JSR-303. This support is enabled automatically if a JSR-303 provider, such as Hibernate Validator, is present on your classpath. When enabled, you can trigger validation simply by annotating a Controller method parameter with the @Valid annotation: After binding incoming POST parameters, the AppointmentForm will be validated; in this case, to verify the date field value is not null and occurs in the future.

My python version is 3.6.7

The OS failed to install the required update Windows8.1-KB2999226-x64.msu. However I tried to find the particular update from -

C:\ProgramData\Package Cache\469A82B09E217DDCF849181A586DF1C97C0C5C85\packages\Patch\amd64\Windows8.1-KB2999226-x64.msu.

I couldn't find it there so I installed the kb2999226 update from here (Windows 10 Universal C runtime)

Then I installed the update according to my OS and after that It was working fine.

It is likely that your phone's iOS version is not supported by your Xcode version. You can verify this by "Adding Additional Simulators", tapping the + sign at the bottom left of that dialog, and then selecting "Download more simulator runtimes..." in the OS Version field. Compare the most recent available OS Version to your phone's iOS version (on your phone go to Settings -> General -> About).

Upgrading Xcode fixes this - so long as that doesn't cause any problems for you. If for some reason you need to stay on the same Xcode version but still need to support a newer iOS version, check this article out: https://davidlaristudios.com/2016/11/adding-device-support-to-xcode/

You can actually copy the device support out of a newer Xcode version and paste it into your Xcode version. Note that this requires that you download the new Xcode version separately - don't upgrade your current version. You can download the newer Xcode version directly from Apple.

Here's how to change the dosbox.conf file in Linux to increase the size of the window. I actually DID what follows, so I can say it works (in 32-bit PCLinuxOS fullmontyKDE, anyway). The question's answer is in the .conf file itself.

You find this file in Linux at /home/(username)/.dosbox . In Konqueror or Dolphin, you must first check 'Hidden files' or you won't see the folder. Open it with KWrite superuser or your fav editor.

1. Save the file with another name like 'dosbox-0.74original.conf' to preserve the original file in case you need to restore it.
2. Search on 'resolution' and carefully read what the conf file says about changing it. There are essentially two variables: resolution and output. You want to leave fullresolution alone for now. Your question was about WINDOW, not full. So look for windowresolution, see what the comments in conf file say you can do. The best suggestion is to use a bigger-window resolution like 900x800 (which is what I used on a 1366x768 screen), but NOT the actual resolution of your machine (which would make the window fullscreen, and you said you didn't want that). Be specific, replacing the 'windowresolution=original' with 'windowresolution=900x800' or other dimensions. On my screen, that doubled the window size just as it does with the max Font tab in Windows Properties (for the exe file; as you'll see below the ==== marks, 32-bit Windows doesn't need Dosbox).

Then, search on 'output', and as the instruction in the conf file warns, if and only if you have 'hardware scaling', change the default 'output=surface' to something else; he then lists the optional other settings. I changed it to 'output=overlay'. There's one other setting to test: aspect. Search the file for 'aspect', and change the 'false' to 'true' if you want an even bigger window. When I did this, the window took up over half of the screen. With 'false' left alone, I had a somewhat smaller window (I use widescreen monitors, whether laptop or desktop, maybe that's why).

So after you've made the changes, save the file with the original name of dosbox-0.74.conf . Then, type dosbox at the command line or create a Launcher (in KDE, this is a right click on the desktop) with the command dosbox. You still have to go through the mount command (i.e., mount c~ c:\123 if that's the location and file you'll execute). I'm sure there's a way to make a script, but haven't yet learned how to do that.

Create a SQLCLR assembly with external access permission that returns the list of files as a result set. There are many examples how to do this, eg. Yet another TVF: returning files from a directory or Trading in xp_cmdshell for SQLCLR (Part 1) - List Directory Contents.

Another solution is to use a Predicate, then you can use this in any filter:

public static <T> Predicate<T> distinctBy(Function<? super T, ?> f) {
  Set<Object> objects = new ConcurrentHashSet<>();
  return t -> objects.add(f.apply(t));
}

Then simply reuse the predicate anywhere:

employees.stream().filter(distinctBy(e -> e.getId));

Note: in the JavaDoc of filter, which says it takes a stateless Predicte. Actually, this works fine even if the stream is parallel.

About other solutions:

1) Using .collect(Collectors.toConcurrentMap(..)).values() is a good solution, but it's annoying if you want to sort and keep the order.

2) stream.removeIf(e->!seen.add(e.getID())); is also another very good solution. But we need to make sure the collection implemented removeIf, for example it will throw exception if we construct the collection use Arrays.asList(..).

If an element has bootstrap's "hide" class and you want to display it with some sliding effect such as .slideDown(), you can cheat bootstrap like:

$('#hiddenElement').hide().removeClass('hide').slideDown('fast')

Simply you can use the following code:

$arr=explode('sep1',str_replace(array('sep2','sep3','sep4'),'sep1',$mystring));

This is an old thread, but for reference it's important to note that disabling an input element's outline is not recommended as it hinders accessibility.

The outline property is there for a reason - providing users with a clear indication of keyboard focus. For further reading and additional sources about this subject see http://outlinenone.com/

One of the fundamental principles behind a promise is that it's handled asynchronously. This means that you cannot create a promise and then immediately use its result synchronously in your code (e.g. it's not possible to return the result of a promise from within the function that initiated the promise).

What you likely want to do instead is to return the entire promise itself. Then whatever function needs its result can call .then() on the promise, and the result will be there when the promise has been resolved.

Here is a resource from HTML5Rocks that goes over the lifecycle of a promise, and how its output is resolved asynchronously:
http://www.html5rocks.com/en/tutorials/es6/promises/

You just add this code

$clasa = (object) array(
            'e1' => array('nume' => 'Nitu', 'prenume' => 'Andrei', 'sex' => 'm', 'varsta' => 23),
            'e2' => array('nume' => 'Nae', 'prenume' => 'Ionel', 'sex' => 'm', 'varsta' => 27),
            'e3' => array('nume' => 'Noman', 'prenume' => 'Alice', 'sex' => 'f', 'varsta' => 22),
            'e4' => array('nume' => 'Geangos', 'prenume' => 'Bogdan', 'sex' => 'm', 'varsta' => 23),
            'e5' => array('nume' => 'Vasile', 'prenume' => 'Mihai', 'sex' => 'm', 'varsta' => 25)
);

If you want to see is this stdClass object just call this

print_r($clasa);

If you want to convert an array to object code will be

$arr = array('a'=>'apple','b'=>'ball');
$arr = (object) $arr;

You don't need to use stdClass. It will automatically converted to stdClass

There are two ways to fix this:

1. Unix Way (simple and recommended)
2. Homebrew Way

1. Unix Way: In 4 simple steps

1. Execute which git in the terminal to know the location of your git executable. Open that directory & locate gitk inside the bin folder. Copy the path --- typically /usr/local/git/bin
2. Edit your ~/.bash_profile to add the location of local git & gitk in the paths or, simply copy-pasta from the sample written below.

Sample bash_profile:

# enabling gitk
export PATH=/usr/local/git/bin:$PATH

3. This step is relevant if you're using El Capitan or higher & you run into an unknown color name “lime” error. Locate gitk executable (typically at /usr/local/bin/gitk), take a backup & open it in a text editor. Find all occurences of lime in the file & replace them with "#99FF00".
4. Reload bash: source ~/.bash_profile

Now, run gitk

2. HomeBrew way

Updates - If you do not have homebrew on your mac, get it installed first. It may require sudo privileges.

• brew update
• brew doctor
• brew link git
• added /usr/local/Cellar/git/2.4.0/bin to path & then reload bash & run gitk
• No luck yet? Proceed further.
• Run which git & observe if git is still linked to /usr/bin/git
• If yes, then open the directory & locate the was a binary executable.
• Take its backup, may be save with a name git.bak & delete the original file
• Reload the terminal - source ~/.bash_profile

Try jQuery animate() method, ex.

$("#divid").animate({'width':perc+'%'});

I would suggest you have a look at BackgroundWorker. If you have a loop that large in your WinForm it will block and your app will look like it has hanged.

Look at BackgroundWorker.ReportProgress() to see how to report progress back to the UI thread.

For example:

private void Calculate(int i)
{
    double pow = Math.Pow(i, i);
}

private void button1_Click(object sender, EventArgs e)
{
    progressBar1.Maximum = 100;
    progressBar1.Step = 1;
    progressBar1.Value = 0;
    backgroundWorker.RunWorkerAsync();
}

private void backgroundWorker_DoWork(object sender, DoWorkEventArgs e)
{
    var backgroundWorker = sender as BackgroundWorker;
    for (int j = 0; j < 100000; j++)
    {
        Calculate(j);
        backgroundWorker.ReportProgress((j * 100) / 100000);
    }
}

private void backgroundWorker_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
    progressBar1.Value = e.ProgressPercentage;
}

private void backgroundWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
    // TODO: do something with final calculation.
}

You can split them very easily using JUnit categories and Maven.
This is shown very, very briefly below by splitting unit and integration tests.

Define A Marker Interface

public interface IntegrationTest {}

Mark your test classes

Add the category annotation to the top of your test class. It takes the name of your new interface.

import org.junit.experimental.categories.Category;

@Category(IntegrationTest.class)
public class ExampleIntegrationTest{

    @Test
    public void longRunningServiceTest() throws Exception {
    }

}

Configure Maven Unit Tests

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.11</version>
    <configuration>
        <includes>
            <include>**/*.class</include>
        </includes>
        <excludedGroups>
            com.test.annotation.type.IntegrationTest
        </excludedGroups>
    </configuration>
</plugin>

When you do a mvn clean test, only your unmarked unit tests will run.

Configure Maven Integration Tests

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-failsafe-plugin</artifactId>
    <version>2.19.1</version>
    <configuration>
        <includes>
            <include>**/*.class</include>
        </includes>
        <groups>
            com.test.annotation.type.IntegrationTest
        </groups>
    </configuration>
</plugin>

The configuration uses a standard execution goal to run the failsafe plugin during the integration-test phase of the build.

You can now do a mvn clean install.
This time as well as the unit tests running, the integration tests are run during the integration-test phase.

In my instance, I decided to solve this via a one-line lambda to create a new decorator function:

def finished_message(function, message="Finished!"):

    def wrapper(*args, **kwargs):
        output = function(*args,**kwargs)
        print(message)
        return output

    return wrapper

@finished_message
def func():
    pass

my_finished_message = lambda f: finished_message(f, "All Done!")

@my_finished_message
def my_func():
    pass

if __name__ == '__main__':
    func()
    my_func()

When executed, this prints:

Finished!
All Done!

Perhaps not as extensible as other solutions, but worked for me.

On the Rails side, params is a method that returns an ActionController::Parameters object. See https://stackoverflow.com/a/44070358/5462485

The syntax for creating a new table is

CREATE TABLE new_table
AS
SELECT *
  FROM old_table

This will create a new table named new_table with whatever columns are in old_table and copy the data over. It will not replicate the constraints on the table, it won't replicate the storage attributes, and it won't replicate any triggers defined on the table.

SELECT INTO is used in PL/SQL when you want to fetch data from a table into a local variable in your PL/SQL block.

Java 8:

String[] strArray = {"eins", "zwei", "drei", "vier"};

Set<String> strSet = Arrays.stream(strArray).collect(Collectors.toSet());
System.out.println(strSet);
// [eins, vier, zwei, drei]

It is very inefficient to store all values in memory, so the objects are reused and loaded one at a time. See this other SO question for a good explanation. Summary:

[...] when looping through the Iterable value list, each Object instance is re-used, so it only keeps one instance around at a given time.

In Python 2, you can input multiple values comma separately (as jcfollower mention in his solution). But if you want to do it explicitly, you can proceed in following way. I am taking multiple inputs from users using a for loop and keeping them in items list by splitting with ','.

items= [x for x in raw_input("Enter your numbers comma separated: ").split(',')]

print items

I am a beginner myself and I honestly couldn't find a satisfactory answer that I could understand or implement.

So here's an external link that I really helped me achieved what I wanted. It's very straight forward and easy to follow as well.

http://www.helloandroid.com/tutorials/how-display-custom-dialog-your-android-application

THIS WHAT I TRIED TO ACHIEVE WITH THE CODE:

I have a MainActivity that hosts a Fragment. I wanted a dialog to appear on top of the layout to ask for user input and then process the input accordingly. See a screenshot

Here's what the onCreateView of my fragment looks

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.fragment_home_activity, container, false);

    Button addTransactionBtn = rootView.findViewById(R.id.addTransactionBtn);

    addTransactionBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Dialog dialog = new Dialog(getActivity());
            dialog.setContentView(R.layout.dialog_trans);
            dialog.setTitle("Add an Expense");
            dialog.setCancelable(true);

            dialog.show();

        }
    });

I hope it will help you

Let me know if there's any confusion. :)

Check out the MSDN page for SortedList:

From Remarks section:

The SortedList<(Of <(TKey, TValue>)>) generic class is a binary search tree with O(log n) retrieval, where n is the number of elements in the dictionary. In this, it is similar to the SortedDictionary<(Of <(TKey, TValue>)>) generic class. The two classes have similar object models, and both have O(log n) retrieval. Where the two classes differ is in memory use and speed of insertion and removal:

• SortedList<(Of <(TKey, TValue>)>) uses less memory than SortedDictionary<(Of <(TKey, TValue>)>).

• SortedDictionary<(Of <(TKey, TValue>)>) has faster insertion and removal operations for unsorted data, O(log n) as opposed to O(n) for SortedList<(Of <(TKey, TValue>)>).

• If the list is populated all at once from sorted data, SortedList<(Of <(TKey, TValue>)>) is faster than SortedDictionary<(Of <(TKey, TValue>)>).

__func__ is an implicitly declared identifier that expands to a character array variable containing the function name when it is used inside of a function. It was added to C in C99. From C99 §6.4.2.2/1:

The identifier __func__ is implicitly declared by the translator as if, immediately following the opening brace of each function definition, the declaration

static const char __func__[] = "function-name";

appeared, where function-name is the name of the lexically-enclosing function. This name is the unadorned name of the function.

Note that it is not a macro and it has no special meaning during preprocessing.

__func__ was added to C++ in C++11, where it is specified as containing "an implementation-de?ned string" (C++11 §8.4.1[dcl.fct.def.general]/8), which is not quite as useful as the specification in C. (The original proposal to add __func__ to C++ was N1642).

__FUNCTION__ is a pre-standard extension that some C compilers support (including gcc and Visual C++); in general, you should use __func__ where it is supported and only use __FUNCTION__ if you are using a compiler that does not support it (for example, Visual C++, which does not support C99 and does not yet support all of C++0x, does not provide __func__).

__PRETTY_FUNCTION__ is a gcc extension that is mostly the same as __FUNCTION__, except that for C++ functions it contains the "pretty" name of the function including the signature of the function. Visual C++ has a similar (but not quite identical) extension, __FUNCSIG__.

For the nonstandard macros, you will want to consult your compiler's documentation. The Visual C++ extensions are included in the MSDN documentation of the C++ compiler's "Predefined Macros". The gcc documentation extensions are described in the gcc documentation page "Function Names as Strings."

All non-private instance methods are virtual by default in Java.

In C++, private methods can be virtual. This can be exploited for the non-virtual-interface (NVI) idiom. In Java, you'd need to make the NVI overridable methods protected.

From the Java Language Specification, v3:

8.4.8.1 Overriding (by Instance Methods) An instance method m1 declared in a class C overrides another instance method, m2, declared in class A iff all of the following are true:

1. C is a subclass of A.
2. The signature of m1 is a subsignature (§8.4.2) of the signature of m2.
3. Either * m2 is public, protected or declared with default access in the same package as C, or * m1 overrides a method m3, m3 distinct from m1, m3 distinct from m2, such that m3 overrides m2.

Idea 8.0 has the lovely ctrl+shift+space x 2 that does the following autocomplete:

 City city = customer.<ctrl-shift-space twice>

resolves to

 City city = customer.getAddress().getCity();

through any number of levels of getters/setters.

As the @Ayush answer:

As you can see sizeWithFont at Apple Developer site it is deprecated so we need to use sizeWithAttributes.

Well, supposing that in 2019+ you are probably using Swift and String instead of Objective-c and NSString, here's the correct way do get the size of a String with predefined font:

let stringSize = NSString(string: label.text!).size(withAttributes: [.font : UIFont(name: "OpenSans-Regular", size: 15)!])

It is simple, as a java, Android also supporting singleton. -

Singleton is a part of Gang of Four design pattern and it is categorized under creational design patterns.

-> Static member : This contains the instance of the singleton class.

-> Private constructor : This will prevent anybody else to instantiate the Singleton class.

-> Static public method : This provides the global point of access to the Singleton object and returns the instance to the client calling class.

1. create private instance
2. create private constructor

3. use getInstance() of Singleton class

   public class Logger{
   private static Logger   objLogger;
   private Logger(){
   
           //ToDo here
   
   }
   public static Logger getInstance()
   {
       if (objLogger == null)
      {
         objLogger = new Logger();
      }
      return objLogger;
      }
   
   }
   

while use singleton -

Logger.getInstance();

in newer versions of Angular with window as an any

(window as any).open(someUrl, "_blank");

Simple but like a charm:

    $period = new DatePeriod(new DateTime('2015-01-01'), new DateInterval('P1D'), new DateTime('2015-01-15 +1 day'));
    foreach ($period as $date) {
        $dates[] = $date->format("Y-m-d");
    }

    //ONLY SHOWING
    echo '<pre>';
    var_dump($dates);
    echo '</pre>';
    exit();

Perhaps you could use a FileSystemWatcher and watch for the Changed event.

I haven't used this myself, but it might be worth a shot. If the filesystemwatcher turns out to be a bit heavy for this case, I would go for the try/catch/sleep loop.

If your UML modeling tool has support for specifying an Enumeration, you should use that. It will likely be easier to do and it will give your model stronger semantics. Visually the result will be very similar to a Class with an <<enumeration>> Stereotype, but in the UML metamodel, an Enumeration is actually a separate (meta)type.

+---------------------+
|   <<enumeration>>   |
|    DayOfTheWeek     |
|_____________________|

| Monday              |
| Tuesday             |
| ...                 |
+---------------------+

Once it is defined, you can use it as the type of an Attribute just like you would a Datatype or the name one of your own Classes.

+---------------------+

If you're using ArgoEclipse or ArgoUML, there's a pulldown menu on the toolbar which selects among Datatype, Enumeration, Signal, etc that will allow you to create your own Enumerations. The compartment that normally contains Attributes can then be populated with EnumerationLiterals for the values of your enumeration.

Here's a picture of a slightly different example in ArgoUML:

Or you can do

docker run -v /var/volume1 -v /var/volume2 DATA busybox true

TL;DR you should just update the existing remote:

$ git remote set-url origin [email protected]:ppreyer/first_app.git

Long version:

As the error message indicates, there is already a remote configured with the same name. So you can either add the new remote with a different name or update the existing one if you don't need it:

To add a new remote, called for example github instead of origin (which obviously already exists in your system), do the following:

$ git remote add github [email protected]:ppreyer/first_app.git

Remember though, everywhere in the tutorial you see "origin" you should replace it with "github". For example $ git push origin master should now be $ git push github master.

However, if you want to see what that origin which already exists is, you can do a $ git remote -v. If you think this is there by some error, you can update it like so:

$ git remote set-url origin [email protected]:ppreyer/first_app.git

Here is how I solved the issue, might be useful to some:

Ajax modal doesn't seem to be available with boostrap 2.1.1

So I ended up coding it myself:

$('[data-toggle="modal"]').click(function(e) {
  e.preventDefault();
  var url = $(this).attr('href');
  //var modal_id = $(this).attr('data-target');
  $.get(url, function(data) {
      $(data).modal();
  });
});

Example of a link that calls a modal:

<a href="{{ path('ajax_get_messages', { 'superCategoryID': 6, 'sex': sex }) }}" data-toggle="modal">
    <img src="{{ asset('bundles/yopyourownpoet/images/messageCategories/BirthdaysAnniversaries.png') }}" alt="Birthdays" height="120" width="109"/>
</a>

I now send the whole modal markup through ajax.

str.isalpha()

Return true if all characters in the string are alphabetic and there is at least one character, false otherwise. Alphabetic characters are those characters defined in the Unicode character database as “Letter”, i.e., those with general category property being one of “Lm”, “Lt”, “Lu”, “Ll”, or “Lo”. Note that this is different from the “Alphabetic” property defined in the Unicode Standard.

In python2.x:

>>> s = u'a1??'
>>> for char in s: print char, char.isalpha()
...
a True
1 False
? True
? True
>>> s = 'a1??'
>>> for char in s: print char, char.isalpha()
...
a True
1 False
? False
? False
? False
? False
? False
? False
>>>

In python3.x:

>>> s = 'a1??'
>>> for char in s: print(char, char.isalpha())
...
a True
1 False
? True
? True
>>>

This code work:

>>> def is_alpha(word):
...     try:
...         return word.encode('ascii').isalpha()
...     except:
...         return False
...
>>> is_alpha('??')
False
>>> is_alpha(u'??')
False
>>>

>>> a = 'a'
>>> b = 'a'
>>> ord(a), ord(b)
(65345, 97)
>>> a.isalpha(), b.isalpha()
(True, True)
>>> is_alpha(a), is_alpha(b)
(False, True)
>>>

You must dereference the iterator in order to retrieve the member of your set.

std::set<unsigned long>::iterator it;
for (it = SERVER_IPS.begin(); it != SERVER_IPS.end(); ++it) {
    u_long f = *it; // Note the "*" here
}

If you have C++11 features, you can use a range-based for loop:

for(auto f : SERVER_IPS) {
  // use f here
}    

If date string is like 2018-07-20T12:18:29.802Z Use this

SimpleDateFormat fmt = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");

To show months as Jan 2017 Feb 2017 etc:

scale_x_date(date_breaks = "1 month", date_labels =  "%b %Y") 

Angle the dates if they take up too much space:

theme(axis.text.x=element_text(angle=60, hjust=1))

Correcting gradle settings is quite difficult. If you don't know much about Gradle it requires you to learn alot. Instead you can do the following:

1) Start a new project in a new folder. Choose the same settings with your project with gradle problem but keep it simple: Choose an empty main activity. 2) Delete all the files in ...\NewProjectName\app\src\main folder 3) Copy all the files in ...\ProjectWithGradleProblem\app\src\main folder to ...\NewProjectName\app\src\main folder. 4) If you are using the Test project (\ProjectWithGradleProblem\app\src\AndroidTest) you can do the same for that too.

this method works fine if your Gradle installation is healthy. If you just installed Android studio and did not modify it, the Gradle installation should be fine.

Using Android default libraries like AppCompat, you can convert all the PDF pages into images. This way is very fast and optimized. The below code is for getting separate images of a PDF page. It is very fast and quick.

ParcelFileDescriptor fileDescriptor = ParcelFileDescriptor.open(new File("pdfFilePath.pdf"), MODE_READ_ONLY);
    PdfRenderer renderer = new PdfRenderer(fileDescriptor);
    final int pageCount = renderer.getPageCount();
    for (int i = 0; i < pageCount; i++) {
        PdfRenderer.Page page = renderer.openPage(i);
        Bitmap bitmap = Bitmap.createBitmap(page.getWidth(), page.getHeight(),Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(bitmap);
        canvas.drawColor(Color.WHITE);
        canvas.drawBitmap(bitmap, 0, 0, null);
        page.render(bitmap, null, null, PdfRenderer.Page.RENDER_MODE_FOR_DISPLAY);
        page.close();

        if (bitmap == null)
            return null;

        if (bitmapIsBlankOrWhite(bitmap))
            return null;

        String root = Environment.getExternalStorageDirectory().toString();
        File file = new File(root + filename + ".png");

        if (file.exists()) file.delete();
        try {
            FileOutputStream out = new FileOutputStream(file);
            bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
            Log.v("Saved Image - ", file.getAbsolutePath());
            out.flush();
            out.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

=======================================================

private static boolean bitmapIsBlankOrWhite(Bitmap bitmap) {
    if (bitmap == null)
        return true;

    int w = bitmap.getWidth();
    int h = bitmap.getHeight();
    for (int i =  0; i < w; i++) {
        for (int j = 0; j < h; j++) {
            int pixel =  bitmap.getPixel(i, j);
            if (pixel != Color.WHITE) {
                return false;
            }
        }
    }
    return true;
}

The receiver must set port of receiver to match port set in sender DatagramPacket. For debugging try listening on port > 1024 (e.g. 8000 or 9000). Ports < 1024 are typically used by system services and need admin access to bind on such a port.

If the receiver sends packet to the hard-coded port it's listening to (e.g. port 57) and the sender is on the same machine then you would create a loopback to the receiver itself. Always use the port specified from the packet and in case of production software would need a check in any case to prevent such a case.

Another reason a packet won't get to destination is the wrong IP address specified in the sender. UDP unlike TCP will attempt to send out a packet even if the address is unreachable and the sender will not receive an error indication. You can check this by printing the address in the receiver as a precaution for debugging.

In the sender you set:

 byte [] IP= { (byte)192, (byte)168, 1, 106 };
 InetAddress address = InetAddress.getByAddress(IP);

but might be simpler to use the address in string form:

 InetAddress address = InetAddress.getByName("192.168.1.106");

In other words, you set target as 192.168.1.106. If this is not the receiver then you won't get the packet.

Here's a simple UDP Receiver that works :

import java.io.IOException;
import java.net.*;

public class Receiver {

    public static void main(String[] args) {
        int port = args.length == 0 ? 57 : Integer.parseInt(args[0]);
        new Receiver().run(port);
    }

    public void run(int port) {    
      try {
        DatagramSocket serverSocket = new DatagramSocket(port);
        byte[] receiveData = new byte[8];
        String sendString = "polo";
        byte[] sendData = sendString.getBytes("UTF-8");

        System.out.printf("Listening on udp:%s:%d%n",
                InetAddress.getLocalHost().getHostAddress(), port);     
        DatagramPacket receivePacket = new DatagramPacket(receiveData,
                           receiveData.length);

        while(true)
        {
              serverSocket.receive(receivePacket);
              String sentence = new String( receivePacket.getData(), 0,
                                 receivePacket.getLength() );
              System.out.println("RECEIVED: " + sentence);
              // now send acknowledgement packet back to sender     
              DatagramPacket sendPacket = new DatagramPacket(sendData, sendData.length,
                   receivePacket.getAddress(), receivePacket.getPort());
              serverSocket.send(sendPacket);
        }
      } catch (IOException e) {
              System.out.println(e);
      }
      // should close serverSocket in finally block
    }
}

In addition to the posts above:

Application.Current.DispatcherUnhandledException

will not catch exceptions that are thrown from a thread other than the main thread. You have to catch those exceptions on the same thread they are thrown. But if you want to Handle them on your global exception handler you can pass it to the main thread:

 System.Threading.Thread t = new System.Threading.Thread(() =>
    {
        try
        {
            ...
            //this exception will not be catched by 
            //Application.DispatcherUnhandledException
            throw new Exception("huh..");
            ...
        }
        catch (Exception ex)
        {
            //But we can handle it in the throwing thread
            //and pass it to the main thread wehre Application.
            //DispatcherUnhandledException can handle it
            System.Windows.Application.Current.Dispatcher.Invoke(
                System.Windows.Threading.DispatcherPriority.Normal,
                new Action<Exception>((exc) =>
                    {
                      throw new Exception("Exception from another Thread", exc);
                    }), ex);
        }
    });

Looks like divs will not go outside of their body's width. Even within another div.

I threw this up to test (without a doctype though) and it does not work as thought.

.slideContainer {_x000D_
    overflow-x: scroll;_x000D_
}_x000D_
.slide {_x000D_
    float: left;_x000D_
}

What i am thinking is that the inner div's could be loaded through an iFrame, since that is another page and its content could be very wide.

I was not able to get this working entirely based on the suggestions above. Including the DataTypeAttribute [DataType(DataType.Date)] seemed to solve my issue, see:

Model

public DateTime RptDate { get; set; }

Definitely svn, since Windows is—at best—a second-class citizen in the world of git (see http://en.wikipedia.org/wiki/Git_(software)#Portability for more details).

UPDATE: Sorry for the broken link, but I've given up trying to get SO to work with URIs that contain parentheses. [link fixed now. -ed]

The sleep man page says it is declared in <unistd.h>.

Synopsis:

#include <unistd.h>

unsigned int sleep(unsigned int seconds);

Excellent solution! I noticed when I tried to implement it that if I returned a value in the success clause, it came back as undefined. I had to store it in a variable and return that variable. This is the method I came up with:

function getWhatever() {
  // strUrl is whatever URL you need to call
  var strUrl = "", strReturn = "";

  jQuery.ajax({
    url: strUrl,
    success: function(html) {
      strReturn = html;
    },
    async:false
  });

  return strReturn;
}

I added this helper method to handle my POST requests that return an object I care about.

For REST purists, I know, POSTs should not return anything besides a status. However, I had a large collection of ids that was too big for a query string parameter.

Helper Method:

    public TResponse Post<TResponse>(string relativeUri, object postBody) where TResponse : new()
    {
        //Note: Ideally the RestClient isn't created for each request. 
        var restClient = new RestClient("http://localhost:999");

        var restRequest = new RestRequest(relativeUri, Method.POST)
        {
            RequestFormat = DataFormat.Json
        };

        restRequest.AddBody(postBody);

        var result = restClient.Post<TResponse>(restRequest);

        if (!result.IsSuccessful)
        {
            throw new HttpException($"Item not found: {result.ErrorMessage}");
        }

        return result.Data;
    }

Usage:

    public List<WhateverReturnType> GetFromApi()
    {
        var idsForLookup = new List<int> {1, 2, 3, 4, 5};

        var relativeUri = "/api/idLookup";

        var restResponse = Post<List<WhateverReturnType>>(relativeUri, idsForLookup);

        return restResponse;
    }

Okay. If you do not want to store the file in database and store in the application, like assets (custom folder), you can define non-db instance variable defined by attr_accessor: document and use form_for - f.file_field to get the file,

In controller,

 @person = Person.new(person_params)

Here person_params return whitelisted params[:person] (define yourself)

Save file as,

dir = "#{Rails.root}/app/assets/custom_path"
FileUtils.mkdir(dir) unless File.directory? dir
document = @person.document.document_file_name # check document uploaded params
File.copy_stream(@font.document, "#{dir}/#{document}")

Note, Add this path in .gitignore & if you want to use this file again add this path asset_pathan of application by application.rb

Whenever form read file field, it get store in tmp folder, later you can store at your place, I gave example to store at assets

note: Storing files like this will increase the size of the application, better to store in the database using paperclip.

There are quite lots of answer based on situation.

1) Try to replace '$' with "jQuery"

2) Check that code you are executed are always below the main jquery script.

<script src="http://code.jquery.com/jquery-1.11.3.min.js"></script>
<script type="text/javascript">
jQuery(document).ready(function(){

});
</script>

3) Pass $ into the function and add "jQuery" as a main function like below.

<script type="text/javascript">
jQuery(document).ready(function($){

});
</script>

If by "restart", you mean to start a new 4 second interval at this moment, then you must stop and restart the timer.

function myFn() {console.log('idle');}

var myTimer = setInterval(myFn, 4000);

// Then, later at some future time, 
// to restart a new 4 second interval starting at this exact moment in time
clearInterval(myTimer);
myTimer = setInterval(myFn, 4000);

You could also use a little timer object that offers a reset feature:

function Timer(fn, t) {
    var timerObj = setInterval(fn, t);

    this.stop = function() {
        if (timerObj) {
            clearInterval(timerObj);
            timerObj = null;
        }
        return this;
    }

    // start timer using current settings (if it's not already running)
    this.start = function() {
        if (!timerObj) {
            this.stop();
            timerObj = setInterval(fn, t);
        }
        return this;
    }

    // start with new or original interval, stop current interval
    this.reset = function(newT = t) {
        t = newT;
        return this.stop().start();
    }
}

Usage:

var timer = new Timer(function() {
    // your function here
}, 5000);


// switch interval to 10 seconds
timer.reset(10000);

// stop the timer
timer.stop();

// start the timer
timer.start();

This helped me at the end:

Quick guide:

• Download Google USB Driver

• Connect your device with Android Debugging enabled to your PC

• Open Device Manager of Windows from System Properties.

• Your device should appear under Other devices listed as something like Android ADB Interface or 'Android Phone' or similar. Right-click that and click on Update Driver Software...

• Select Browse my computer for driver software

• Select Let me pick from a list of device drivers on my computer

• Double-click Show all devices

• Press the Have disk button

• Browse and navigate to [wherever your SDK has been installed]\google-usb_driver and select android_winusb.inf

• Select Android ADB Interface from the list of device types.

• Press the Yes button

• Press the Install button

• Press the Close button

Now you've got the ADB driver set up correctly. Reconnect your device if it doesn't recognize it already.

The second option really isn't the same as the others - if the string is "///foo" it will become "foo" instead of "//foo".

The first option needs a bit more work to understand than the third - I would view the Substring option as the most common and readable.

(Obviously each of them as an individual statement won't do anything useful - you'll need to assign the result to a variable, possibly data itself.)

I wouldn't take performance into consideration here unless it was actually becoming a problem for you - in which case the only way you'd know would be to have test cases, and then it's easy to just run those test cases for each option and compare the results. I'd expect Substring to probably be the fastest here, simply because Substring always ends up creating a string from a single chunk of the original input, whereas Remove has to at least potentially glue together a start chunk and an end chunk.

I think it's a version problem, you just have to uninstall the old version of composer, then do a new installation of its new version.

 apt remove composer

and follow the steps:

1. download the composer from its official release site by making use of the following command.

 wget https://getcomposer.org/download/1.6.3/composer.phar

2. Before you proceed with the installation, you should rename before you install and make it an executable file.

  mv composer.phar composer

  chmod +x composer

3. Now install the package by making use the following command.

 ./composer

4. The composer has been successfully installed now, make it access globally using the following command. for Ubuntu 16

 mv composer /usr/bin/

for Ubuntu 18

 mv composer /usr/local/bin/

Use CSS3 PIE, which emulates some CSS3 properties in older versions of IE.

It supports box-shadow (except for the inset keyword).

No, you can't get it quite like background-size:cover but..

This approach is pretty damn close: it uses JavaScript to determine if the image is landscape or portrait, and applies styles accordingly.

        }else{
            $(this).addClass('tall-img');

If you want force stop your thread: thread._Thread_stop() For me works very good.

This is untested, but I believe the syntax should work for a lambda query. As you join more tables with this syntax you have to drill further down into the new objects to reach the values you want to manipulate.

var fullEntries = dbContext.tbl_EntryPoint
    .Join(
        dbContext.tbl_Entry,
        entryPoint => entryPoint.EID,
        entry => entry.EID,
        (entryPoint, entry) => new { entryPoint, entry }
    )
    .Join(
        dbContext.tbl_Title,
        combinedEntry => combinedEntry.entry.TID,
        title => title.TID,
        (combinedEntry, title) => new 
        {
            UID = combinedEntry.entry.OwnerUID,
            TID = combinedEntry.entry.TID,
            EID = combinedEntry.entryPoint.EID,
            Title = title.Title
        }
    )
    .Where(fullEntry => fullEntry.UID == user.UID)

In Kotlin 1.2 simply call:

and the onCreateOptionsMenu function will be called again.

tl;dr

Duration d = Duration.ofMillis( … ) ;
int minutes = d.toMinutesPart() ;
int seconds = d.toSecondsPart() ;

Java 9 and later

In Java 9 and later, create a Duration and call the to…Part methods. In this case: toMinutesPart and toSecondsPart.

Capture the start & stop of your stopwatch.

Instant start = Instant.now(); 
…
Instant stop = Instant.now();

Represent elapsed time in a Duration object.

Duration d = Duration.between( start , stop );

Interrogate for each part, the minutes and the seconds.

int minutes = d.toMinutesPart();
int seconds = d.toSecondsPart();

You might also want to see if your stopwatch ran expectedly long.

Boolean ranTooLong = ( d.toDaysPart() > 0 ) || ( d.toHoursPart() > 0 ) ;

Java 8

In Java 8, the Duration class lacks to…Part methods. You will need to do math as shown in the other Answers.

long entireDurationAsSeconds = d.getSeconds();

Or let Duration do the math.

long minutesPart = d.toMinutes(); 
long secondsPart = d.minusMinutes( minutesPart ).getSeconds() ;

See live code in IdeOne.com.

Interval: 2016-12-18T08:39:34.099Z/2016-12-18T08:41:49.099Z

d.toString(): PT2M15S

d.getSeconds(): 135

Elapsed: 2M 15S

Resolution

FYI, the resolution of now methods changed between Java 8 and Java 9. See this Question.

• Java 9 captures the moment with a resolution as fine as nanoseconds. Resolution depends on capability of your computer’s hardware. I see microseconds (six digits of decimal fraction) on MacBook Pro Retina with macOS Sierra.
• Java 8 captures the moment only up to milliseconds. The implementation of Clock is limited to a resolution of milliseconds. So you can store values in nanoseconds but only capture them in milliseconds.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

I always like to use Ansi escape characters:

echo -e "Enter your password: \x1B[8m"
echo -e "\x1B[0m"

8m makes text invisible and 0m resets text to "normal." The -e makes Ansi escapes possible.

The only caveat is that you can still copy and paste the text that is there, so you probably shouldn't use this if you really want security.

It just lets people not look at your passwords when you type them in. Just don't leave your computer on afterwards. :)

NOTE:

The above is platform independent as long as it supports Ansi escape sequences.

However, for another Unix solution, you could simply tell read to not echo the characters...

printf "password: "
let pass $(read -s)
printf "\nhey everyone, the password the user just entered is $pass\n"

LIBRARY_PATH is used by gcc before compilation to search directories containing static and shared libraries that need to be linked to your program.

LD_LIBRARY_PATH is used by your program to search directories containing shared libraries after it has been successfully compiled and linked.

EDIT: As pointed below, your libraries can be static or shared. If it is static then the code is copied over into your program and you don't need to search for the library after your program is compiled and linked. If your library is shared then it needs to be dynamically linked to your program and that's when LD_LIBRARY_PATH comes into play.

You can simply replace all \n with <br/> tag so that when page is displayed then it breaks line.

I got the very easy solution for this - setting different width for column in style sheet by overriding the both cell and header cell:

Example - setting custom width for 1st and 5th column:

  flex: 0 0 5%;
}
.mat-cell:nth-child(5),
.mat-header-cell:nth-child(5) {
  flex: 0 0 10%;
}

The difference between joins and include is that using the include statement generates a much larger SQL query loading into memory all the attributes from the other table(s).

For example, if you have a table full of comments and you use a :joins => users to pull in all the user information for sorting purposes, etc it will work fine and take less time than :include, but say you want to display the comment along with the users name, email, etc. To get the information using :joins, it will have to make separate SQL queries for each user it fetches, whereas if you used :include this information is ready for use.

Great example:

http://railscasts.com/episodes/181-include-vs-joins

You don't actually need a form to do this with Prototype. Just use Object.toQueryString function:

Object.toQueryString({ action: 'ship', order_id: 123, fees: ['f1', 'f2'], 'label': 'a demo' })

// -> 'action=ship&order_id=123&fees=f1&fees=f2&label=a%20demo'

$("#year").datepicker( {
    format: "yyyy",
    viewMode: "years", 
    minViewMode: "years"
}).on('changeDate', function(e){
    $(this).datepicker('hide');
});

The accepted answer (its image) is wrong, at least now in QT5. Instead you should assign a layout to the root object/widget (pointing to the aforementioned image, it should be the MainWindow instead of centralWidget). Also note that you must have at least one QObject created beneath it for this to work. Do this and your ui will become responsive to window resizing.

I consider that is important to mention here that the following attributes are also very important:

STAThreadAttribute 

Indicates that the COM threading model for an application is single-threaded apartment (STA).

For example this attribute is used in Windows Forms Applications:

static class Program
{
    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new Form1());
    }
}

And also ...

SuppressMessageAttribute

Suppresses reporting of a specific static analysis tool rule violation, allowing multiple suppressions on a single code artifact.

For example:

[SuppressMessage("Microsoft.Performance", "CA1801:ReviewUnusedParameters", MessageId = "isChecked")]
[SuppressMessage("Microsoft.Performance", "CA1804:RemoveUnusedLocals", MessageId = "fileIdentifier")]
static void FileNode(string name, bool isChecked)
{
    string fileIdentifier = name;
    string fileName = name;
    string version = String.Empty;
}

Maybe you are trying to set it in Apache's php.ini, but your CLI (Command Line Interface) php.ini is not good.

Find your php.ini file with the following command:

php -i | grep php.ini

And then search for date.timezone and set it to "Europe/Amsterdam". all valid timezone will be found here http://php.net/manual/en/timezones.php

Another way (if the other does not work), search for the file AppKernel.php, which should be under the folder app of your Symfony project directory. Overwrite the __construct function below in the class AppKernel:

<?php     

class AppKernel extends Kernel
{
    // Other methods and variables


    // Append this init function below

    public function __construct($environment, $debug)
    {
        date_default_timezone_set( 'Europe/Paris' );
        parent::__construct($environment, $debug);
    }

}

You can use LENGTH() for CHAR / VARCHAR2 and DBMS_LOB.GETLENGTH() for CLOB. Both functions will count actual characters (not bytes).

See the linked documentation if you do need bytes.

I thought that @Steven 's answer was the best one, and took care of a lot more cases than if the incoming value was just a string. I wanted to extend it a bit and offer the following:

function isTrue(value){
    if (typeof(value) === 'string'){
        value = value.trim().toLowerCase();
    }
    switch(value){
        case true:
        case "true":
        case 1:
        case "1":
        case "on":
        case "yes":
            return true;
        default: 
            return false;
    }
}

It's not necessary to cover all the false cases if you already know all of the true cases you'd have to account for. You can pass anything into this method that could pass for a true value (or add others, it's pretty straightforward), and everything else would be considered false

You should be pointing it towards the Developer directory, not the Xcode application bundle. Run this:

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

With recent versions of Xcode, you can go to Xcode ? Preferences… ? Locations and pick one of the options for Command Line Tools to set the location.

The Swiss Army knife of image lazy loading is YUI's ImageLoader.

Because there is more to this problem than simply watching the scroll position.

You could use itertools's takewhile like this, it will stop once a condition is met that fails your statement. The opposite method would be dropwhile

for x in itertools.takewhile(lambda x: x[2] == 0, list)
    print x

You can also use sqlalchemy builtin function for default DateTime

from sqlalchemy.sql import func

DT = Column(DateTime(timezone=True), default=func.now())

Check what git remote -v returns: the account used to push to an http url is usually embedded into the remote url itself.

https://[email protected]/...

If that is the case, put an url which will force Git to ask for the account to use when pushing:

git remote set-url origin https://github.com/<user>/<repo>

Or one to use the Fre1234 account:

git remote set-url origin https://[email protected]/<user>/<repo>

Also check if you installed your Git For Windows with or without a credential helper as in this question.

The OP Fre1234 adds in the comments:

I finally found the solution.
Go to: Control Panel -> User Accounts -> Manage your credentials -> Windows Credentials

Under Generic Credentials there are some credentials related to Github,
Click on them and click "Remove".

That is because the default installation for Git for Windows set a Git-Credential-Manager-for-Windows.
See git config --global credential.helper output (it should be manager)

For Ubuntu 14.04 and Android try:

hcitool scan #get hardware address
sudo bluetooth-agent PIN HARDWARE-ADDRESS

PIN dialog pops up on Android device. Enter same PIN.

Note: sudo apt-get install bluez-utils might be necessary.

Note2: If PIN dialog does not appear, try pairing from Android first (will fail because of wrong PIN). Then try again as described above.

I have been waiting to see if Google would open a Keep API. When I discovered Google Tasks, and saw that it had an Android app, web app, and API, I converted over to Tasks. This may not directly answer your question, but it is my solution to the Keep API problem.

Tasks doesn't have a reminder alarm exactly like Keep. I can live without that if I also connect with the Calendar API.

The other methods work fine, but you can also use the good old django.shortcut.redirect.

The code below was taken from this answer.

In Django 2.x:

from django.shortcuts import redirect
from django.urls import path, include

urlpatterns = [
    # this example uses named URL 'hola-home' from app named hola
    # for more redirect's usage options: https://docs.djangoproject.com/en/2.1/topics/http/shortcuts/
    path('', lambda request: redirect('hola/', permanent=True)),
    path('hola/', include('hola.urls')),
]

Now we can add a picture to Excel directly and easely. Just follow these instructions:

1. Go to the Insert tab.
2. Click on the Pictures option (it’s in the illustrations group).
3. In the ‘Insert Picture’ dialog box, locate the pictures that you want to insert into a cell in Excel.
4. Click on the Insert button.
5. Re-size the picture/image so that it can fit perfectly within the cell.
6. Place the picture in the cell. A cool way to do this is to first press the ALT key and then move the picture with the mouse. It will snap and arrange itself with the border of the cell as soon it comes close to it.

If you have multiple images, you can select and insert all the images at once (as shown in step 4).

You can also resize images by selecting it and dragging the edges. In the case of logos or product images, you may want to keep the aspect ratio of the image intact. To keep the aspect ratio intact, use the corners of an image to resize it.

When you place an image within a cell using the steps above, it will not stick with the cell in case you resize, filter, or hide the cells. If you want the image to stick to the cell, you need to lock the image to the cell it’s placed n.

To do this, you need to follow the additional steps as shown below.

1. Right-click on the picture and select Format Picture.
2. In the Format Picture pane, select Size & Properties and with the options in Properties, select ‘Move and size with cells’.

Now you can move cells, filter it, or hide it, and the picture will also move/filter/hide.

NOTE:

This answer was taken from this link: Insert Picture into a Cell in Excel.

To learn what row was selected, add a ListSelectionListener, as shown in How to Use Tables in the example SimpleTableSelectionDemo. A JList can be constructed directly from the linked list's toArray() method, and you can add a suitable listener to it for details.

You need to use anchors to match the beginning of the string ^ and the end of the string $

^[0-9]{2}$

HttpServerUtility.UrlEncode will use HttpUtility.UrlEncode internally. There is no specific difference. The reason for existence of Server.UrlEncode is compatibility with classic ASP.

this worked for me:-

<?php echo '<pre>' . print_r($_SESSION, TRUE) . '</pre>'; ?>
