Check if you have set restrict outgoing SMTP to only some system users (root, MTA, mailman...). That restriction may prevent the spammers, but will redirect outgoing SMTP connections to the local mail server.

I had the same error but I discovered that when you import an AddEventModule, you can't import an AddEvent module as it would present an error in this case.

I modified @Geuis 's answer by using lambda and convert it upper case first:

people.sort((a, b) => a.toLocaleUpperCase() < b.toLocaleUpperCase() ? -1 : 1);

You can also use this command on the command line:

mvn dependency:purge-local-repository clean install

function getRangeDateString($timestamp) {
    if ($timestamp) {
        $currentTime=strtotime('today');
        // Reset time to 00:00:00
        $timestamp=strtotime(date('Y-m-d 00:00:00',$timestamp));
        $days=round(($timestamp-$currentTime)/86400);
        switch($days) {
            case '0';
                return 'Today';
                break;
            case '-1';
                return 'Yesterday';
                break;
            case '-2';
                return 'Day before yesterday';
                break;
            case '1';
                return 'Tomorrow';
                break;
            case '2';
                return 'Day after tomorrow';
                break;
            default:
                if ($days > 0) {
                    return 'In '.$days.' days';
                } else {
                    return ($days*-1).' days ago';
                }
                break;
        }
    }
}

NEVER EVER use a selector like DATE(datecolumns) = '2012-12-24' - it is a performance killer:

• it will calculate DATE() for all rows, including those, that don't match
• it will make it impossible to use an index for the query

It is much faster to use

SELECT * FROM tablename 
WHERE columname BETWEEN '2012-12-25 00:00:00' AND '2012-12-25 23:59:59'

as this will allow index use without calculation.

EDIT

As pointed out by Used_By_Already, in the time since the inital answer in 2012, there have emerged versions of MySQL, where using '23:59:59' as a day end is no longer safe. An updated version should read

SELECT * FROM tablename 
WHERE columname >='2012-12-25 00:00:00'
AND columname <'2012-12-26 00:00:00'

The gist of the answer, i.e. the avoidance of a selector on a calculated expression, of course still stands.

If you only plan to work with one key in particular, you may accomplish this with a single line without having to store an array for all of the keys:

echo array_keys($array)[$i];

My work-around for Symfony build having loot of instances at the same server:

Step 1. Create trigger or something to set a file flag (eg. Symfony command) then create marker file ..

file_put_contents('clearAPCU','yes sir i can buggy')

Step 2. On index file at start add clearing code and remove marker file.

if(file_exists('clearAPCU')){
    apcu_clear_cache();
    unlink('clearAPCU');
}

Step 2. Run app.

None of the solutions here worked for me out of the box, but it was most likely due my lack of experience with VBA. It might also be because I simply copied and pasted some of the functions above, not knowing details that maybe are necessary to make them work on a VBA for applications environment.

My needs were simply to send xmlhttp requests using urls that contained some special characters of the Norwegian language. Some of the solutions above encode even colons, which made the urls unsuitable for what I needed.

I then decided to write my own URLEncode function. It does not use more clever programming such as the one from @ndd and @Tom. I am not a very experienced programmer, but I had to make this done sooner.

I realized that the problem was that my server didn't accept UTF-16 encodings, so I had to write a function that would convert UTF-16 to UTF-8. A good source of information was found here and here.

I haven't tested it extensively to check if it works with url with characters that have higher unicode values and which would produce more than 2 bytes of utf-8 characters. I am not saying it will decode everything that needs to be decoded (but it is easy to modify to include/exclude characters on the select case statement) nor that it will work with higher characters, as I haven't fully tested. But I am sharing the code because it might help someone who is trying to understand the issue.

Any comments are welcome.

With jQuery you could use the .each function to iterate through the links with the following code:

$(document).ready(function() {
    $("[href]").each(function() {
        if (this.href == window.location.href) {
            $(this).addClass("active");
        }
    });
});

Depending on your page structure and used links, you may have to narrow down the selection of links like:

$("nav [href]").each ...

If you are using URL parameters, it may be necessary to strip these:

if (this.href.split("?")[0] == window.location.href.split("?")[0]) ...

This way you don't have to edit each page.

To get started with dotnet core, SqlServer and EF core the below DBContextOptionsBuilder would sufice and you do not need to create App.config file. Do not forget to change the sever address and database name in the below code.

protected override void OnConfiguring(DbContextOptionsBuilder options)
        => options.UseSqlServer(@"Server=(localdb)\MSSQLLocalDB;Database=TestDB;Trusted_Connection=True;");

To use the EF core SqlServer provider and compile the above code install the EF SqlServer package

dotnet add package Microsoft.EntityFrameworkCore.SqlServer

After compilation before running the code do the following for the first time

dotnet tool install --global dotnet-ef
dotnet add package Microsoft.EntityFrameworkCore.Design
dotnet ef migrations add InitialCreate
dotnet ef database update

To run the code

dotnet run

You can write a method that takes the type as a generic parameter:

void GenericProcessMessage<T>(T message)
{
    MessageProcessor<T> processor = messageProcessors[typeof(T)]
        as MessageProcessor<T>;

    //  Call method processor or whatever you need to do
}

Then you need a way to call the method with the correct generic argument. You can do this with reflection:

public void ProcessMessage(object message)
{
    Type messageType = message.GetType();
    MethodInfo method = this.GetType().GetMethod("GenericProcessMessage");
    MethodInfo closedMethod = method.MakeGenericMethod(messageType);
    closedMethod.Invoke(this, new object[] {message});
}

/**
     * Converts a local Unix timestamp to GMT
     *
     * @param   int Unix timestamp
     * @return  int
     */
    function local_to_gmt($time = '')
    {
        if ($time === '')
        {
            $time = time();
        }

        return mktime(
            gmdate('G', $time),
            gmdate('i', $time),
            gmdate('s', $time),
            gmdate('n', $time),
            gmdate('j', $time),
            gmdate('Y', $time)
        );
    }

Cast them to a Number

$('#total_price').val(Number(a)+Number(b));

But before you do that

if (!isNaN($('input[name=service_price]').val()) {...

This is a recursive algorithm to sort by multiple fields while having the chance to format values before comparison.

var data = [
{
    "id": 1,
    "ship": null,
    "product": "Orange",
    "quantity": 7,
    "price": 92.08,
    "discount": 0
},
{
    "id": 2,
    "ship": "2017-06-14T23:00:00.000Z".toDate(),
    "product": "Apple",
    "quantity": 22,
    "price": 184.16,
    "discount": 0
},
...
]
var sorts = ["product", "quantity", "ship"]

// comp_val formats values and protects against comparing nulls/undefines
// type() just returns the variable constructor
// String.lower just converts the string to lowercase.
// String.toDate custom fn to convert strings to Date
function comp_val(value){
    if (value==null || value==undefined) return null
    var cls = type(value)
    switch (cls){
        case String:
            return value.lower()
    }
    return value
}

function compare(a, b, i){
    i = i || 0
    var prop = sorts[i]
    var va = comp_val(a[prop])
    var vb = comp_val(b[prop])

    // handle what to do when both or any values are null
    if (va == null || vb == null) return true

    if ((i < sorts.length-1) && (va == vb)) {
        return compare(a, b, i+1)
    } 
    return va > vb
}

var d = data.sort(compare);
console.log(d);

If a and b are equal it will just try the next field until none is available.

After installation/upgrading node via brew I ran into this issue exactly: the node command worked but not the npm command.

I used these commands to fix it.

brew uninstall node
brew update
brew upgrade
brew cleanup
brew install node
sudo chown -R $(whoami) /usr/local
brew link --overwrite node
brew postinstall node

I pieced together this solution after trial and error using...

• a github thread: https://github.com/npm/npm/issues/3125

• this site: http://developpeers.com/blogs/fix-for-homebrew-permission-denied-issues

I experienced this issue and couldn't figure out a fix for a few hours, until I realised I had incorrectly prevented native events from occurring with:

<input type="checkbox" @click.prevent="toggleConfirmedStatus(render.uuid)"
    :checked="confirmed.indexOf(render.uuid) > -1"
    :value="render.uuid"
/>

removing the .prevent from the @click handler fixed my issue.

There's a killer script on github that fixes perms on /usr/local and brew directories to be accessible by anyone who is a member of the 'admin' group.

https://gist.github.com/jaibeee/9a4ea6aa9d428bc77925

This is a better solution than the chosen answer, since if you chown the /usr/local/___ directories to $USER, then you break any other admin users of homebrew on that machine.

Here are the guts of the script at the time I posted this:

chgrp -R admin /usr/local
chmod -R g+w /usr/local

chgrp -R admin /Library/Caches/Homebrew
chmod -R g+w /Library/Caches/Homebrew

chgrp -R admin /opt/homebrew-cask
chmod -R g+w /opt/homebrew-cask

I was getting ó in $mail->Subject /w PHPMailer.

So for me the complete solution is:

// Your Subject with tildes. Example.
$someSubjectWithTildes = 'Subscripción España';

$mailer->CharSet = 'UTF-8';
$mailer->Encoding = 'quoted-printable';
$mailer->Subject = html_entity_decode($someSubjectWithTildes);

Hope it helps.

This Technical Note TN2328 from Apple Developer Library helped me a lot about Changes To Embedding Python Using Xcode 5.0.

I just figured out how to remove this gradle error, follow the following steps.

1. Go to "File".
2. Click on Invalidate Cache/ Restart.
3. Again click on Invalidate Cache / Restart(On dialoge window).

Let the gradle build without any interruption.

Thank You! Regards, hope this will help.

I use HttpWebRequest to GET from the web service, which returns me a JSON string. It looks something like this for a GET:

// Returns JSON string
string GET(string url) 
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
    try {
        WebResponse response = request.GetResponse();
        using (Stream responseStream = response.GetResponseStream()) {
            StreamReader reader = new StreamReader(responseStream, System.Text.Encoding.UTF8);
            return reader.ReadToEnd();
        }
    }
    catch (WebException ex) {
        WebResponse errorResponse = ex.Response;
        using (Stream responseStream = errorResponse.GetResponseStream())
        {
            StreamReader reader = new StreamReader(responseStream, System.Text.Encoding.GetEncoding("utf-8"));
            String errorText = reader.ReadToEnd();
            // log errorText
        }
        throw;
    }
}

I then use JSON.Net to dynamically parse the string. Alternatively, you can generate the C# class statically from sample JSON output using this codeplex tool: http://jsonclassgenerator.codeplex.com/

POST looks like this:

// POST a JSON string
void POST(string url, string jsonContent) 
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
    request.Method = "POST";

    System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding();
    Byte[] byteArray = encoding.GetBytes(jsonContent);

    request.ContentLength = byteArray.Length;
    request.ContentType = @"application/json";

    using (Stream dataStream = request.GetRequestStream()) {
        dataStream.Write(byteArray, 0, byteArray.Length);
    }
    long length = 0;
    try {
        using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) {
            length = response.ContentLength;
        }
    }
    catch (WebException ex) {
        // Log exception and throw as for GET example above
    }
}

I use code like this in automated tests of our web service.

It seems important to exactly match the format of the ISO string for TryParseExact to work. I guess Exact is Exact and this answer is obvious to most but anyway...

In my case, Reb.Cabin's answer doesn't work as I have a slightly different input as per my "value" below.

Value: 2012-08-10T14:00:00.000Z

There are some extra 000's in there for milliseconds and there may be more.

However if I add some .fff to the format as shown below, all is fine.

Format String: @"yyyy-MM-dd\THH:mm:ss.fff\Z"

In VS2010 Immediate Window:

DateTime.TryParseExact(value,@"yyyy-MM-dd\THH:mm:ss.fff\Z", CultureInfo.InvariantCulture,DateTimeStyles.AssumeUniversal, out d);

true

You may have to use DateTimeStyles.AssumeLocal as well depending upon what zone your time is for...

Try to install JST Server Adapters and JST Server Adapters Extentions. I am running Eclipse 4.4.2 Luna and it worked.

Here are the steps I followed:

1. Help -> Install New Software

2. Choose "Luna - http://download.eclipse.org/releases/luna" site

3. Expand "Web, XML, and Java EE Development"

4. Check JST Server Adapters and JST Server Adapters Extentions

Wanted to ADD to the other answers described here an additional note, in the case of custom exceptions.

In the case where you create your own custom exception, that derives from std::exception, when you catch "all possible" exceptions types, you should always start the catch clauses with the "most derived" exception type that may be caught. See the example (of what NOT to do):

#include <iostream>
#include <string>

using namespace std;

class MyException : public exception
{
public:
    MyException(const string& msg) : m_msg(msg)
    {
        cout << "MyException::MyException - set m_msg to:" << m_msg << endl;
    }

   ~MyException()
   {
        cout << "MyException::~MyException" << endl;
   }

   virtual const char* what() const throw () 
   {
        cout << "MyException - what" << endl;
        return m_msg.c_str();
   }

   const string m_msg;
};

void throwDerivedException()
{
    cout << "throwDerivedException - thrown a derived exception" << endl;
    string execptionMessage("MyException thrown");
    throw (MyException(execptionMessage));
}

void illustrateDerivedExceptionCatch()
{
    cout << "illustrateDerivedExceptionsCatch - start" << endl;
    try 
    {
        throwDerivedException();
    }
    catch (const exception& e)
    {
        cout << "illustrateDerivedExceptionsCatch - caught an std::exception, e.what:" << e.what() << endl;
        // some additional code due to the fact that std::exception was thrown...
    }
    catch(const MyException& e)
    {
        cout << "illustrateDerivedExceptionsCatch - caught an MyException, e.what::" << e.what() << endl;
        // some additional code due to the fact that MyException was thrown...
    }

    cout << "illustrateDerivedExceptionsCatch - end" << endl;
}

int main(int argc, char** argv)
{
    cout << "main - start" << endl;
    illustrateDerivedExceptionCatch();
    cout << "main - end" << endl;
    return 0;
}

NOTE:

0) The proper order should be vice-versa, i.e.- first you catch (const MyException& e) which is followed by catch (const std::exception& e).

1) As you can see, when you run the program as is, the first catch clause will be executed (which is probably what you did NOT wanted in the first place).

2) Even though the type caught in the first catch clause is of type std::exception, the "proper" version of what() will be called - cause it is caught by reference (change at least the caught argument std::exception type to be by value - and you will experience the "object slicing" phenomena in action).

3) In case that the "some code due to the fact that XXX exception was thrown..." does important stuff WITH RESPECT to the exception type, there is misbehavior of your code here.

4) This is also relevant if the caught objects were "normal" object like: class Base{}; and class Derived : public Base {}...

5) g++ 7.3.0 on Ubuntu 18.04.1 produces a warning that indicates the mentioned issue:

In function ‘void illustrateDerivedExceptionCatch()’: item12Linux.cpp:48:2: warning: exception of type ‘MyException’ will be caught catch(const MyException& e) ^~~~~

item12Linux.cpp:43:2: warning: by earlier handler for ‘std::exception’ catch (const exception& e) ^~~~~

Again, I will say, that this answer is only to ADD to the other answers described here (I thought this point is worth mention, yet could not depict it within a comment).

If you only want to get one day it would be easier this way:

Comment.all(:conditions => ["date(created_at) = ?", some_date])

div[disabled]
{
  pointer-events: none;
  opacity: 0.6;
  background: rgba(200, 54, 54, 0.5);  
  background-color: yellow;
  filter: alpha(opacity=50);
  zoom: 1;  
  -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=50)";  
  -moz-opacity: 0.5; 
  -khtml-opacity: 0.5;  
}

Inside of your <head></head> tags add...

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script>
$(document).ready(function(){
    $('input[type=radio]').change(function() {

    $('input[type=radio]').each(function(index) {
        $(this).closest('tr').removeClass('selected');
    });

        $(this).closest('tr').addClass('selected');
    });
});
</script>

EDIT: The placement inside of <head></head> is not the only option...this could just as easily be placed RIGHT before the closing </body> tag. I generally try and place my JavaScript inside of head for placement reasons, but it can in some cases slow down page rendering so some will recommend the latter approach (before closing body).

What about this?

edit user's .bashprofile adding:

export LAST_DAY_OF_MONTH=$(cal | awk '!/^$/{ print $NF }' | tail -1)

Then add this entry to crontab:

mm hh * * 1-7 [[ $(date +'%d') -eq $LAST_DAY_OF_MONTH ]] && /absolutepath/myscript.sh

In general, if you don't know how something works, look for an example which you can learn from.

For this problem, consider this DEMO

You can see loading content with AJAX is very easily accomplished with jQuery:

$(function(){
    // don't cache ajax or content won't be fresh
    $.ajaxSetup ({
        cache: false
    });
    var ajax_load = "<img src='http://automobiles.honda.com/images/current-offers/small-loading.gif' alt='loading...' />";

    // load() functions
    var loadUrl = "http://fiddle.jshell.net/deborah/pkmvD/show/";
    $("#loadbasic").click(function(){
        $("#result").html(ajax_load).load(loadUrl);
    });

// end  
});

Try to understand how this works and then try replicating it. Good luck.

You can find the corresponding tutorial HERE

Update

Right now the following event starts the ajax load function:

$("#loadbasic").click(function(){
        $("#result").html(ajax_load).load(loadUrl);
    });

You can also do this periodically: How to fire AJAX request Periodically?

(function worker() {
  $.ajax({
    url: 'ajax/test.html', 
    success: function(data) {
      $('.result').html(data);
    },
    complete: function() {
      // Schedule the next request when the current one's complete
      setTimeout(worker, 5000);
    }
  });
})();

I made a demo of this implementation for you HERE. In this demo, every 2 seconds (setTimeout(worker, 2000);) the content is updated.

You can also just load the data immediately:

$("#result").html(ajax_load).load(loadUrl);

Which has THIS corresponding demo.

            button.setOnClickListener(this);

            // add generated button to view
            if (i == 0) {

        // add generated layouts to root layout view
       // LinearLayout root = (LinearLayout)this.findViewById(R.id.root_layout);

        root.addView(top);
        root.addView(bottom);

I recently installed Leap. I Tried openshot and it didn't start. So came here and found a suggestion to start from the Terminal to see if there were any error.

The error I had was error missing mlt. So I installed the python-mlt module from Yast and imported it, tried to start but next openshot said missing pil.

I Followed the Pillow suggestion to install because Yast couldn't find any pil and imported pil. That went ok but did not start and showed Error missing goocanvas.

The I installed goocanvas with Yast, imported it in python, and Openshot fired up !!

With a lot of errors in the terminal like missing Vimeoclient and lots of attributeerrors. Well, will see if it is of any influence working with it.

You can use the annotate command to place text annotations at any x and y values you want. To place them exactly at the data points you could do this

import numpy
from matplotlib import pyplot

x = numpy.arange(10)
y = numpy.array([5,3,4,2,7,5,4,6,3,2])

fig = pyplot.figure()
ax = fig.add_subplot(111)
ax.set_ylim(0,10)
pyplot.plot(x,y)
for i,j in zip(x,y):
    ax.annotate(str(j),xy=(i,j))

pyplot.show()

If you want the annotations offset a little, you could change the annotate line to something like

ax.annotate(str(j),xy=(i,j+0.5))

>>> xs = [["A",0], ["B",1], ["C",0], ["D",2], ["E",2]]
>>> xs.sort(key=lambda x: x[1])
>>> reduce(lambda l, x: (l.append([x]) if l[-1][0][1] != x[1] else l[-1].append(x)) or l, xs[1:], [[xs[0]]]) if xs else []
[[['A', 0], ['C', 0]], [['B', 1]], [['D', 2], ['E', 2]]]

Basically, if the list is sorted, it is possible to reduce by looking at the last group constructed by the previous steps - you can tell if you need to start a new group, or modify an existing group. The ... or l bit is a trick that enables us to use lambda in Python. (append returns None. It is always better to return something more useful than None, but, alas, such is Python.)

Well if you want to look into this differently, you just need to know what are options does the React has that non exhaustive-deps? One of the reason you should not use a closure function inside the effect is on every render, it will be re-created/destroy again.

So there are multiple React methods in hooks that is considered stable and non-exhausted where you do not have to apply to the useEffect dependencies, and in turn will not break the rules engagement of react-hooks/exhaustive-deps. For example the second return variable of useReducer or useState which is a function.

const [,dispatch] = useReducer(reducer, {});

useEffect(() => {
    dispatch(); // non-exhausted, eslint won't nag about this
}, []);

So in turn you can have all your external dependencies together with your current dependencies coexist together within your reducer function.

const [,dispatch] = useReducer((current, update) => {
    const { foobar } = update;
    // logic

    return { ...current, ...update };
}), {});

const [foobar, setFoobar] = useState(false);

useEffect(() => {
    dispatch({ foobar }); // non-exhausted `dispatch` function
}, [foobar]);

If you have problems like that, first of all your TC folder put in to the C:..drive. after completing installation open turbo c blue screen. there is a OPTIONS > Directories ..in that you can see for option to set up path..

1. include directories..you can set path there now.. C:\TC\INCUDE
2. libraries Directories..you can set path there...C:\TC\LIB
3. if you want to store your output in BIN then you can set..C:\TC\BIN..otherwise you can set another path where you want to store your output..

Finally you can give OK and finished processes.. It will now work properly

You can pass in the data to be used in the mouseover like this- the mouseover event uses a function with your previously entered data as an argument (and the index as a second argument) so you don't need to use enter() a second time.

vis.selectAll("circle")
.data(datafiltered).enter().append("svg:circle")
.attr("cx", function(d) { return x(d.x);})
.attr("cy", function(d) {return y(d.y)})
.attr("fill", "red").attr("r", 15)
.on("mouseover", function(d,i) {
    d3.select(this).append("text")
        .text( d.x)
        .attr("x", x(d.x))
        .attr("y", y(d.y)); 
});

All the above answers technically answer the asker's question, but just thought I'd point out a case where you might encounter problems.

If you declare your struct like this:

typedef struct{
int x;
foo(){};
} foo;

You will have problems trying to declare a constructor. This is of course because you haven't actually declared a struct named "foo", you've created an anonymous struct and assigned it the alias "foo". This also means you will not be able to use "foo" with a scoping operator in a cpp file:

foo.h:

typedef struct{
int x;
void myFunc(int y);
} foo;

foo.cpp:

//<-- This will not work because the struct "foo" was never declared.
void foo::myFunc(int y)
{
  //do something...
}

To fix this, you must either do this:

struct foo{
int x;
foo(){};
};

or this:

typedef struct foo{
int x;
foo(){};
} foo;

Where the latter creates a struct called "foo" and gives it the alias "foo" so you don't have to use the struct keyword when referencing it.

$(document).ready(function(){

    $('#mySelect').append("<option>BMW</option>")

})

Apart from the ones mentioned above, your CUDA installations path (if not changed during setup) typically contains the version number

doing a which nvcc should give the path and that will give you the version

PS: This is a quick and dirty way, the above answers are more elegant and will result in the right version with considerable effort

Let's take an example.

Your application is located in /var/www/myApp on some Linux server

.htaccess : /var/www/myApp/.htaccess

htpasswdApp : /var/www/myApp/htpasswdApp. (You're free to use any name for .htpasswd file)

To use relative path in .htaccess:

AuthType Digest
AuthName myApp
AuthUserFile "htpasswdApp"
Require valid-user

But it will search for file in server_root directory. Not in document_root.

In out case, when application is located at /var/www/myApp :

document_root is /var/www/myApp

server_root is /etc/apache2 //(just in our example, because of we using the linux server)

You can redefine it in your apache configuration file ( /etc/apache2/apache2.conf), but I guess it's a bad idea.

So to use relative file path in your /var/www/myApp/.htaccess you should define the password's file in your server_root.

I prefer to do it by follow command:

sudo ln -s /var/www/myApp/htpasswdApp /etc/apache2/htpasswdApp

You're free to copy my command, use a hard link instead of symbol,or copy a file to your server_root.

You can use a factory to create the login context. Then you can mock the factory and return whatever you want for your test.

public class TestedClass {
  private final LoginContextFactory loginContextFactory;

  public TestedClass(final LoginContextFactory loginContextFactory) {
    this.loginContextFactory = loginContextFactory;
  }

  public LoginContext login(String user, String password) {
    LoginContext lc = loginContextFactory.createLoginContext();
  }
}

public interface LoginContextFactory {
  public LoginContext createLoginContext();
}

i found the solution. i have installed 2 versions of jre sdk 1.3 and jre7 so i uninstall the older version sdk1.3 then it works.

To display the all details for each news post title ie. "news.id" which is the primary key, you need to use GROUP BY clause for "news.id"

SELECT news.id, users.username, news.title, news.date,
       news.body, COUNT(comments.id)
FROM news
LEFT JOIN users
ON news.user_id = users.id
LEFT JOIN comments
ON comments.news_id = news.id
GROUP BY news.id

A ListView is basically like a ListBox (and inherits from it), but it also has a View property. This property allows you to specify a predefined way of displaying the items. The only predefined view in the BCL (Base Class Library) is GridView, but you can easily create your own.

Another difference is the default selection mode: it's Single for a ListBox, but Extended for a ListView

You're confusing the braces. Do it like this:

target.write("%s \n %s \n %s \n" % (line1, line2, line3))

Or even better, use writelines:

target.writelines([line1, line2, line3])

You should be using the command substitution syntax $(command) when you want to execute a command in script/command.

So your line would be

name=$(echo "$filename" | cut -f 1 -d '.')

Code explanation:

1. echo get the value of the variable $filename and send it to standard output
2. We then grab the output and pipe it to the cut command
3. The cut will use the . as delimiter (also known as separator) for cutting the string into segments and by -f we select which segment we want to have in output
4. Then the $() command substitution will get the output and return its value
5. The returned value will be assigned to the variable named name

Note that this gives the portion of the variable up to the first period .:

$ filename=hello.world
$ echo "$filename" | cut -f 1 -d '.'
hello
$ filename=hello.hello.hello
$ echo "$filename" | cut -f 1 -d '.'
hello
$ filename=hello
$ echo "$filename" | cut -f 1 -d '.'
hello

?? Here is an easy way to remember the scope of public, protected and private.

PUBLIC:

• public scope: A public variable/function is available to both objects and other classes.

PROTECTED:

• protected scope: A protected variable/function is available to all the classes that extend the current class.
• No! Objects cannot access this scope

PRIVATE:

• private scope: A private variable/function is only visible in the current class where it is being defined.
• No! Class that extend the current class cannot access this scope.
• No! Objects cannot access this scope.

Read the Visibility of a method or variable on PHP Manual.

When I uninstalled Java 8 it worked fine.

For column types Rails supports out of the box - like the string in this question - the best approach is to set the column default in the database itself as Daniel Kristensen indicates. Rails will introspect on the DB and initialize the object accordingly. Plus, that makes your DB safe from somebody adding a row outside of your Rails app and forgetting to initialize that column.

For column types Rails doesn't support out of the box - e.g. ENUM columns - Rails won't be able to introspect the column default. For these cases you do not want to use after_initialize (it is called every time an object is loaded from the DB as well as every time an object is created using .new), before_create (because it occurs after validation), or before_save (because it occurs upon update too, which is usually not what you want).

Rather, you want to set the attribute in a before_validation on: create, like so:

before_validation :set_status_because_rails_cannot, on: :create

def set_status_because_rails_cannot
  self.status ||= 'P'
end

This is the most coder-friendly version of specifying a unicode character:

degree_sign= u'\N{DEGREE SIGN}'

Note: must be a capital N in the \N construct to avoid confusion with the '\n' newline character. The character name inside the curly braces can be any case.

It's easier to remember the name of a character than its unicode index. It's also more readable, ergo debugging-friendly. The character substitution happens at compile time: the .py[co] file will contain a constant for u'°':

>>> import dis
>>> c= compile('u"\N{DEGREE SIGN}"', '', 'eval')
>>> dis.dis(c)
  1           0 LOAD_CONST               0 (u'\xb0')
              3 RETURN_VALUE
>>> c.co_consts
(u'\xb0',)
>>> c= compile('u"\N{DEGREE SIGN}-\N{EMPTY SET}"', '', 'eval')
>>> c.co_consts
(u'\xb0-\u2205',)
>>> print c.co_consts[0]
°-Ø

To include Unicode characters in your Python source code, you can use Unicode escape characters in the form \u0123 in your string. In Python 2.x, you also need to prefix the string literal with 'u'.

Here's an example running in the Python 2.x interactive console:

>>> print u'\u0420\u043e\u0441\u0441\u0438\u044f'
??????

In Python 2, prefixing a string with 'u' declares them as Unicode-type variables, as described in the Python Unicode documentation.

In Python 3, the 'u' prefix is now optional:

>>> print('\u0420\u043e\u0441\u0441\u0438\u044f')
??????

If running the above commands doesn't display the text correctly for you, perhaps your terminal isn't capable of displaying Unicode characters.

These examples use Unicode escapes (\u...), which allows you to print Unicode characters while keeping your source code as plain ASCII. This can help when working with the same source code on different systems. You can also use Unicode characters directly in your Python source code (e.g. print u'??????' in Python 2), if you are confident all your systems handle Unicode files properly.

For information about reading Unicode data from a file, see this answer:

Character reading from file in Python

There is also a convenient shortcut to get all elements of the array starting with specified index. For example "${A[@]:1}" would be the "tail" of the array, that is the array without its first element.

version=4.7.1
A=( ${version//\./ } )
echo "${A[@]}"    # 4 7 1
B=( "${A[@]:1}" )
echo "${B[@]}"    # 7 1

A colleague of mine suggested the following: you can use a custom RunListener and implement the testRunFinished() method: http://junit.sourceforge.net/javadoc/org/junit/runner/notification/RunListener.html#testRunFinished(org.junit.runner.Result)

To register the RunListener just configure the surefire plugin as follows: http://maven.apache.org/surefire/maven-surefire-plugin/examples/junit.html section "Using custom listeners and reporters"

This configuration should also be picked by the failsafe plugin. This solution is great because you don't have to specify Suites, lookup test classes or any of this stuff - it lets Maven to do its magic, waiting for all tests to finish.

The only solution that work for me was put npx tsc -v or for the compiling npx tsc salida.ts

"salida.ts" is the name of the file

git reset and git clean can be overkill in some situations (and be a huge waste of time).

If you simply have a message like "The following untracked files would be overwritten..." and you want the remote/origin/upstream to overwrite those conflicting untracked files, then git checkout -f <branch> is the best option.

If you're like me, your other option was to clean and perform a --hard reset then recompile your project.

It looks like you're trying to run it on a version of ASP.NET which is running CLR v2. It's hard to know exactly what's going on without more information about how you've deployed it, what version of IIS you're running etc (and to be frank I wouldn't be very much help at that point anyway, though others would). But basically, check your IIS and ASP.NET set-up, and make sure that everything is running v4. Check your application pool configuration, etc.

run conda navigator, you can upgrade your packages easily in the friendly GUI

I believe you are having the same problem here.
The sheet must be active before you can select a range on it.

Also, don't omit the sheet name qualifier:

Sheets("BxWsn Simulation").Select
Sheets("BxWsn Simulation").Range("Result").Select

Or,

With Sheets("BxWsn Simulation")
  .Select
  .Range("Result").Select
End WIth

which is the same.

Windows Character Encoding Issue

I was having the same issue. I was editing files in PDT Eclipse on Windows and WinSCPing them over. I just copied and pasted the contents into a nano window, saved, and now they worked. Definitely some Windows character encoding issue, and not a matter of Shebangs or interpreter flags.

the following implements A friend's suggestion

#!/bin/bash
rcut(){

  nu="$( echo $1 | cut -d"$DELIM" -f 2-  )"
  if [ "$nu" != "$1" ]
  then
    rcut "$nu"
  else
    echo "$nu"
  fi
}

$ export DELIM=.
$ rcut a.b.c.d
d

As long as ManagementObjectCollection implements IEnumerable<ManagementObject> you can do:

List<ManagementObject> managementList = new List<ManagementObjec>(managementObjects);

If it doesn't, then you are stuck doing it the way that you are doing it.

First of all: you should always import mockito static, this way the code will be much more readable (and intuitive):

import static org.mockito.Mockito.*;

For partial mocking and still keeping original functionality on the rest mockito offers "Spy".

You can use it as follows:

private World world = spy(new World());

To eliminate a method from being executed you could use something like this:

doNothing().when(someObject).someMethod(anyObject());

to give some custom behaviour to a method use "when" with an "thenReturn":

doReturn("something").when(this.world).someMethod(anyObject());

For more examples please find the excellent mockito samples in the doc.

A double quote character (") can be escaped as ", but here's the rest of the story...

Double quote character must be escaped in this context:

• In XML attributes delimited by double quotes:

  <EscapeNeeded name="Pete &quot;Maverick&quot; Mitchell"/>
  

Double quote character need not be escaped in most contexts:

• In XML textual content:

  <NoEscapeNeeded>He said, "Don't quote me."</NoEscapeNeeded>
  

• In XML attributes delimited by single quotes ('):

  <NoEscapeNeeded name='Pete "Maverick" Mitchell'/>
  

  Similarly, (') require no escaping if (") are used for the attribute value delimiters:

  <NoEscapeNeeded name="Pete 'Maverick' Mitchell"/>

I suggest to use this plugin flutter_easyloading

flutter_easyloading is clean and lightweight Loading widget for Flutter App, easy to use without context, support iOS and Android

Add this to your package's pubspec.yaml file:

dependencies:
  flutter_easyloading: ^2.0.0

Now in your Dart code, you can use:

import 'package:flutter_easyloading/flutter_easyloading.dart';

To use First, initialize FlutterEasyLoading in MaterialApp/CupertinoApp

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter EasyLoading',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(title: 'Flutter EasyLoading'),
      builder: EasyLoading.init(),
    );
  }
}

EasyLoading is a singleton, so you can custom loading style any where like this:

import 'dart:async';
import 'package:flutter/material.dart';
import 'package:flutter/cupertino.dart';
import 'package:flutter_easyloading/flutter_easyloading.dart';
import './custom_animation.dart';

void main() {
  runApp(MyApp());
  configLoading();
}

void configLoading() {
  EasyLoading.instance
    ..displayDuration = const Duration(milliseconds: 2000)
    ..indicatorType = EasyLoadingIndicatorType.fadingCircle
    ..loadingStyle = EasyLoadingStyle.dark
    ..indicatorSize = 45.0
    ..radius = 10.0
    ..progressColor = Colors.yellow
    ..backgroundColor = Colors.green
    ..indicatorColor = Colors.yellow
    ..textColor = Colors.yellow
    ..maskColor = Colors.blue.withOpacity(0.5)
    ..userInteractions = true
    ..customAnimation = CustomAnimation();
}

Then, use per your requirement

import 'package:flutter/material.dart';
import 'package:flutter_easyloading/flutter_easyloading.dart';
import 'package:dio/dio.dart';

class TestPage extends StatefulWidget {
  @override
  _TestPageState createState() => _TestPageState();
}

class _TestPageState extends State<TestPage> {
  @override
  void initState() {
    super.initState();
    // EasyLoading.show();
  }

  @override
  void deactivate() {
    EasyLoading.dismiss();
    super.deactivate();
  }

  void loadData() async {
    try {
      EasyLoading.show();
      Response response = await Dio().get('https://github.com');
      print(response);
      EasyLoading.dismiss();
    } catch (e) {
      EasyLoading.showError(e.toString());
      print(e);
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Flutter EasyLoading'),
      ),
      body: Center(
        child: FlatButton(
          textColor: Colors.blue,
          child: Text('loadData'),
          onPressed: () {
            loadData();
            // await Future.delayed(Duration(seconds: 2));
            // EasyLoading.show(status: 'loading...');
            // await Future.delayed(Duration(seconds: 5));
            // EasyLoading.dismiss();
          },
        ),
      ),
    );
  }
}

The semantics of LinkedHashMap are still those of a Map, rather than that of a LinkedList. It retains insertion order, yes, but that's an implementation detail, rather than an aspect of its interface.

The quickest way to get the "first" entry is still entrySet().iterator().next(). Getting the "last" entry is possible, but will entail iterating over the whole entry set by calling .next() until you reach the last. while (iterator.hasNext()) { lastElement = iterator.next() }

edit: However, if you're willing to go beyond the JavaSE API, Apache Commons Collections has its own LinkedMap implementation, which has methods like firstKey and lastKey, which do what you're looking for. The interface is considerably richer.

Check your compileSdkVersion on app build.gradle. Set it to 21:

My site is hosted on Godaddy and I have a private email registered on the same. These are the settings which worked for me:

In settings.py:

EMAIL_HOST = 'mail.domain.com'
EMAIL_HOST_USER = '[email protected]'
EMAIL_HOST_PASSWORD = 'abcdef'
DEFAULT_FROM_EMAIL = '[email protected]'
SERVER_EMAIL = '[email protected]'
EMAIL_PORT = 25
EMAIL_USE_TLS = False

In shell:

from django.core.mail import EmailMessage
email = EmailMessage('Subject', 'Body', to=['[email protected]'])
email.send()

Then I got "1" as the O/P i.e. Success. And I received the mail too. :)

You can find the number of members in a Javascript array by using its length property:

var number = $scope.names.length;

^{Docs - Array.prototype.length}

#Make sure that you specify the port for both http and https ie.
NameVirtualHost:80
NameVirtualHost:443
#and 
<VirtualHost *:80>
<VirtualHost *:443>

#mixing * and *:443 does not work it has to be *:80 and *:443

If you're positive that you will never use this code in a compiler that doesn't support it (Windows/VS, GCC, and Clang are examples of compilers that do support it), then you can certainly use #pragma once without worries.

You can also just use both (see example below), so that you get portability and compilation speedup on compatible systems

#pragma once
#ifndef _HEADER_H_
#define _HEADER_H_

...

#endif

I was having trouble accessing wcf service hosted locally in IIS. Running aspnet_regiis.exe -i wasn't working.

However, I fortunately came across the following:

Rahul's blog

which informs that servicemodelreg also needs to be run:

Run Visual Studio 2008 Command Prompt as “Administrator”. Navigate to C:\Windows\Microsoft.NET\Framework\v3.0\Windows Communication Foundation. Run this command servicemodelreg –i.

I have created little function as workaround solution (inspired by @JohnCulviner plugin):

// creates iframe and form in it with hidden field,
// then submit form with provided data
// url - form url
// data - data to form field
// input_name - form hidden input name

function ajax_download(url, data, input_name) {
    var $iframe,
        iframe_doc,
        iframe_html;

    if (($iframe = $('#download_iframe')).length === 0) {
        $iframe = $("<iframe id='download_iframe'" +
                    " style='display: none' src='about:blank'></iframe>"
                   ).appendTo("body");
    }

                  "</body></html>";

    iframe_doc.open();
    iframe_doc.write(iframe_html);
    $(iframe_doc).find('form').submit();
}

Demo with click event:

$('#someid').on('click', function() {
    ajax_download('/download.action', {'para1': 1, 'para2': 2}, 'dataname');
});

A technique I've used in my own systems, and which I believe is employed by Struts, is to include...

<input type="hidden" name="_fieldname" value="fieldvalue"/> 

...immediately next to the checkbox as part of my form creation logic.

This allows me to reconstruct which checkboxes were served in the form but not selected, with a tiny bit of extra logic to do the diff what was served and what was checked, you have the ones which were unchecked. The submission is also the same in content regardless whether you're using HTML or AJAX style submission.

Depending on the technology you're using server-side then you may wish to use this syntax...

<input type="hidden" name="_fieldname[]" value="fieldvalue"/>

...to make it easy to grab these values as a list.

It seems the original author has found their solution, but for anyone else who gets here looking to add actual custom headers, if you have access to mod the generated Protocol code you can override GetWebRequest:

protected override System.Net.WebRequest GetWebRequest(Uri uri)
{
  System.Net.WebRequest request = base.GetWebRequest(uri);
  request.Headers.Add("myheader", "myheader_value");
  return request;
}

Make sure you remove the DebuggerStepThroughAttribute attribute if you want to step into it.

An alternative to jcoby's proposal would be:

class NilClass
  def nil_or_empty?
    true
  end
end

class String
  def nil_or_empty?
    empty?
  end
end

I think you can also execute this command:

select (sysdate-1) PREVIOUS_DATE from dual;

To add rows to existing DataTable in Dataset:

DataRow drPartMtl = DSPartMtl.Tables[0].NewRow();
drPartMtl["Group"] = "Group";
drPartMtl["BOMPart"] = "BOMPart";
DSPartMtl.Tables[0].Rows.Add(drPartMtl);

Don't need to use this method:

 .map((res: Response) => res.json() );

Just use this simple method instead of the previous method. hopefully you'll get your result:

.map(res => res );

I'd just like to point out something in these answers. In a date/time format string, '/' will be replaced with whatever the user's date separator is, and ':' will be replaced with whatever the user's time separator is. That is, if I've defined my date separator to be '.' (in the Regional and Language Options control panel applet, "intl.cpl"), and my time separator to be '?' (just pretend I'm crazy like that), then

DateTime.Now.ToString("MM/dd/yyyy h:mm tt")

would return

01.05.2009 6?01 PM

In most cases, this is what you want, because you want to respect the user's settings. If, however, you require the format be something specific (say, if it's going to parsed back out by somebody else down the wire), then you need to escape these special characters:

DateTime.Now.ToString("MM\\/dd\\/yyyy h\\:mm tt")

or

DateTime.Now.ToString(@"MM\/dd\/yyyy h\:mm tt")

which would now return

01/05/2009 6:01 PM

EDIT:

Then again, if you really want to respect the user's settings, you should use one of the standard date/time format strings, so that you respect not only the user's choices of separators, but also the general format of the date and/or time.

DateTime.Now.ToShortDateString()
DateTime.Now.ToString("d")

Both would return "1/5/2009" using standard US options, or "05/01/2009" using standard UK options, for instance.

DateTime.Now.ToLongDateString()
DateTime.Now.ToString("D")

Both would return "Monday, January 05, 2009" in US locale, or "05 January 2009" in UK.

DateTime.Now.ToShortTimeString()
DateTime.Now.ToString("t");

"6:01 PM" in US, "18:01" in UK.

DateTime.Now.ToLongTimeString()
DateTime.Now.ToString("T");

"6:01:04 PM" in US, "18:01:04" in UK.

DateTime.Now.ToString()
DateTime.Now.ToString("G");

"1/5/2009 6:01:04 PM" in US, "05/01/2009 18:01:04" in UK.

Many other options are available. See docs for standard date and time format strings and custom date and time format strings.

Here is a code that works for me, which is a part from the website above combined with my early trials: http://www.codeproject.com/KB/system/DriveDetector.aspx

This basically makes your form listen to windows messages, filters for usb drives and (cd-dvds), grabs the lparam structure of the message and extracts the drive letter.

protected override void WndProc(ref Message m)
    {

        if (m.Msg == WM_DEVICECHANGE)
        {
            DEV_BROADCAST_VOLUME vol = (DEV_BROADCAST_VOLUME)Marshal.PtrToStructure(m.LParam, typeof(DEV_BROADCAST_VOLUME));
            if ((m.WParam.ToInt32() == DBT_DEVICEARRIVAL) &&  (vol.dbcv_devicetype == DBT_DEVTYPVOLUME) )
            {
                MessageBox.Show(DriveMaskToLetter(vol.dbcv_unitmask).ToString());
            }
            if ((m.WParam.ToInt32() == DBT_DEVICEREMOVALCOMPLETE) && (vol.dbcv_devicetype == DBT_DEVTYPVOLUME))
            {
                MessageBox.Show("usb out");
            }
        }
        base.WndProc(ref m);
    }

    [StructLayout(LayoutKind.Sequential)] //Same layout in mem
    public struct DEV_BROADCAST_VOLUME
    {
        public int dbcv_size;
        public int dbcv_devicetype;
        public int dbcv_reserved;
        public int dbcv_unitmask;
    }

    private static char DriveMaskToLetter(int mask)
    {
        char letter;
        string drives = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"; //1 = A, 2 = B, 3 = C
        int cnt = 0;
        int pom = mask / 2;
        while (pom != 0)    // while there is any bit set in the mask shift it right        
        {        
            pom = pom / 2;
            cnt++;
        }
        if (cnt < drives.Length)
            letter = drives[cnt];
        else
            letter = '?';
        return letter;
    }

Do not forget to add this:

using System.Runtime.InteropServices;

and the following constants:

    const int WM_DEVICECHANGE = 0x0219; //see msdn site
    const int DBT_DEVICEARRIVAL = 0x8000;
    const int DBT_DEVICEREMOVALCOMPLETE = 0x8004;
    const int DBT_DEVTYPVOLUME = 0x00000002;  

Let's start by the following example:

Now we have 3 options to merge changes of feature branch into master branch:

1. Merge commits
   Will keep all commits history of the feature branch and move them into the master branch
   Will add extra dummy commit.

2. Rebase and merge
   Will append all commits history of the feature branch in the front of the master branch
   Will NOT add extra dummy commit.

3. Squash and merge
   Will group all feature branch commits into one commit then append it in the front of the master branch
   Will add extra dummy commit.

You can find below how the master branch will look after each one of them.

In all cases:
We can safely DELETE the feature branch.

You could use an arbitrary count of arrays and map on the same index new objects.

var array1 = [{ id: "abdc4051", date: "2017-01-24" }, { id: "abdc4052", date: "2017-01-22" }],_x000D_
    array2 = [{ id: "abdc4051", name: "ab" }, { id: "abdc4052", name: "abc" }],_x000D_
    result = [array1, array2].reduce((a, b) => a.map((c, i) => Object.assign({}, c, b[i])));_x000D_
    _x000D_
console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }

Uh you guys...

C:\>findstr /n . c:\boot.ini | findstr ^1:

1:[boot loader]

C:\>findstr /n . c:\boot.ini | findstr ^3:

3:default=multi(0)disk(0)rdisk(0)partition(1)\WINNT

C:\>

If you know the app id of the package (like org.mozilla.firefox), it is easy. First to get the path of actual package file of the appId,

$  adb shell pm list packages -f com.google.android.apps.inbox
package:/data/app/com.google.android.apps.inbox-1/base.apk=com.google.android.apps.inbox

Now you can do some grep|sed magic to extract the path : /data/app/com.google.android.apps.inbox-1/base.apk

After that aapt tool comes in handy :

$  adb shell aapt dump badging /data/app/com.google.android.apps.inbox-1/base.apk
...
application-label:'Inbox'
application-label-hi:'Inbox'
application-label-ru:'Inbox'
...

Again some grep magic to get the Label.

To avoid the race condition @GregPettit mentions, one can use:

($("element").data('bs.modal') || {})._isShown    // Bootstrap 4
($("element").data('bs.modal') || {}).isShown     // Bootstrap <= 3

as discussed in Twitter Bootstrap Modal - IsShown.

When the modal is not yet opened, .data('bs.modal') returns undefined, hence the || {} - which will make isShown the (falsy) value undefined. If you're into strictness one could do ($("element").data('bs.modal') || {isShown: false}).isShown

More details would be useful, but assuming it's a linux system, and assuming php is running under apache, it will run as what ever user apache runs as.

An easy way to check ( again, assuming some unix like environment ) is to create a php file with:

<?php
    print shell_exec( 'whoami' );
?>

which will give you the user.

For my AWS instance, I am getting apache as output when I run this script.

The SQL Query select * from openjson ... works only with SQL version 2016 and higher. Need the SQL compatibility mode 130.

Almost all above solutions used the ActiveDirecotry module which might not be available by default in most cases.

I used below method. A bit indirect, but served my purpose.

List all available groups

Get-WmiObject -Class Win32_Group

And then list the groups the user belongs to

[System.Security.Principal.WindowsIdentity]::GetCurrent().Groups

Comparison can then be done via checking through the SIDs. This works for the logged in user. Please correct me if I am wrong. Completely new to PowerShell, but had to get this done for a work commitment.

More details on how to set the OnKeyListener, and have it listen for the Done button.

First add OnKeyListener to the implements section of your class. Then add the function defined in the OnKeyListener interface:

/*
 * Respond to soft keyboard events, look for the DONE press on the password field.
 */
public boolean onKey(View v, int keyCode, KeyEvent event)
{
    if ((event.getAction() == KeyEvent.ACTION_DOWN) &&
        (keyCode == KeyEvent.KEYCODE_ENTER))
    {
        // Done pressed!  Do something here.
    }
    // Returning false allows other listeners to react to the press.
    return false;
}

Given an EditText object:

EditText textField = (EditText)findViewById(R.id.MyEditText);
textField.setOnKeyListener(this);

In the step 5 of Phil, "Resources" is no longer available in the new version of the Chrome. You need to click the page icon just beside the Ajax page listed in the bottom pane with the columns of Name, Method, Status, ...

Then it will show you more panels where you will find the error messages.

Also you can use a button:

For example, in ASP.NET Core syntax:

// Some other tags
 <form method="post">
      <input asp-for="YourModelPropertyOrYourMethodInputName"
      value="@TheValue" type="hidden" />
      <button type="submit" class="link-button" formaction="/TheDestinationController/TheDestinationActionMethod">
      @(TextValue)
      </button>
  </form>
// Other tags...


<style>
       .link-button {
        background: none !important;
        border: none;
        padding: 0 !important;
        color: #20a8d8;
        cursor: pointer;
    }
</style>

I think you should not use spaces between the [(ngModel)] the = and the str. Then you should use a button or something like this with a click function and in this function you can use the values of your inputfields.

<input id="str" [(ngModel)]="str"/>
<button (click)="sendValues()">Send</button>

and in your component file

str: string;
sendValues(): void {
//do sth with the str e.g. console.log(this.str);
}

Hope I can help you.

The JVM doesn't know anything about off-heap memory. Ehcache implements an on-disk cache as well as an in-memory cache.

If your ajax response are containing html form inputs for instance, than this would be great:

$(document).on("change", 'input[type=radio][name=fieldLoadedFromAjax]', function(event) { 
if (this.value == 'Yes') {
  // do something here
} else if (this.value == 'No') {
  // do something else here.
} else {
   console.log('The new input field from an ajax response has this value: '+ this.value);
}

});

Ran into this issue and was able to solve by 2 main steps:

1 - Update to latest chromedriver via homebrew cli

brew cask upgrade chromedriver

2 - update to lastest ver via Chrome GUI

chrome://settings/help or cmd + , then tacking on help at the end (your choice)

from there you should land on the About Chrome Page. Here you will need to verify that you are on the latest and greatest version (problem i was running into stemmed from a mismatch in the cli vs the current chrome version)

if you getting the error, you will see a update & relaunch primary action button.

after chrome "relaunches" it will now have the newest version matching your cli

example:

Google Chrome is up to date
Version 80.0.3987.87 (Official Build) (64-bit)

This works:

ArrayList<String>[] group = new ArrayList[4];

I had the same issue, due to the fact that I had all the configuration that describe in this post, but in my case was because I had two jquery imports (one of them was primefaces's query) which caused conflicts to upload files.

See Primefaces Jquery conflict

Just to include new Python f String compatible functionality:

var_a = 10

f"""This is my quoted variable: "{var_a}". """

Another option is to create an extra wrapper to center the element vertically.

#container{_x000D_
  border:solid 1px #33aaff;_x000D_
  width:200px;_x000D_
  height:200px;_x000D_
}_x000D_
_x000D_
#helper{_x000D_
  position:relative;_x000D_
  height:50px;_x000D_
  top:50%;_x000D_
  border:dotted 1px #ff55aa;_x000D_
}_x000D_
_x000D_
#centered{_x000D_
  position:relative;_x000D_
  height:50px;_x000D_
  top:-50%;_x000D_
  border:solid 1px #ff55aa;_x000D_
}

<div id="container">_x000D_
  <div id="helper">_x000D_
    <div id="centered"></div>_x000D_
  </div>_x000D_
<div>

You can use templates.

template <typename T> const char* typeof(T&) { return "unknown"; }    // default
template<> const char* typeof(int&) { return "int"; }
template<> const char* typeof(float&) { return "float"; }

In the example above, when the type is not matched it will print "unknown".

Working example

@Repository
public interface TenantRepository extends JpaRepository< Tenant, Long > {
    List<Tenant>findByTenantName(String tenantName,Pageable pageRequest);
    long countByTenantName(String tenantName);
}

Calling from DAO layer

@Override
public long countByTenantName(String tenantName) {
    return repository.countByTenantName(tenantName);
}

You can add as many headers as you like by calling addHeaderView() multiple times. You have to do it before setting the adapter to the list view.

And yes you can add header something like this way:

LayoutInflater inflater = getLayoutInflater();
ViewGroup header = (ViewGroup)inflater.inflate(R.layout.header, myListView, false);
myListView.addHeaderView(header, null, false);

To add to @BrianBeech's answer, this is even more trimmed down in java 8:

jdbcTemplate.query("select string1,string2 from table where x=1", (ResultSet rs) -> {
    HashMap<String,String> results = new HashMap<>();
    while (rs.next()) {
        results.put(rs.getString("string1"), rs.getString("string2"));
    }
    return results;
});

I think transactions belong on the Service layer. It's the one that knows about units of work and use cases. It's the right answer if you have several DAOs injected into a Service that need to work together in a single transaction.

1. add https://momentjs.com/downloads/moment-with-locales.js to your html page
2. var todayDate = moment().format('DD-MM-YYYY');//to get today date 06/03/2018 if you want to add extra day to your current date then
3. var dueDate = moment().add(15,'days').format('DD-MM-YYYY')// to add 15 days to current date..

point 2 and 3 are using in your jquery code...

Have a look at the System.Diagnostics namespace. Lots of goodies in there!

System.Diagnostics.StackTrace t = new System.Diagnostics.StackTrace();

This is really good to have a poke around in to learn whats going on under the hood.

I'd recommend that you have a look into logging solutions (Such as NLog, log4net or the Microsoft patterns and practices Enterprise Library) which may achieve your purposes and then some. Good luck mate!

Solution using just POST - no $_SESSION

page1.php

<form action="page2.php" method="post">
    <textarea name="textarea1" id="textarea1"></textarea><br />
    <input type="submit" value="submit" />
</form>

page2.php

<?php
    // this page outputs the contents of the textarea if posted
    $textarea1 = ""; // set var to avoid errors
    if(isset($_POST['textarea1'])){
        $textarea1 = $_POST['textarea1']
    }
?>
<textarea><?php echo $textarea1;?></textarea>

Solution using $_SESSION and POST

page1.php

<?php

    session_start(); // needs to be before anything else on page to use $_SESSION
    $textarea1 = "";
    if(isset($_POST['textarea1'])){
        $_SESSION['textarea1'] = $_POST['textarea1'];
    }

?>


<form action="page1.php" method="post">
    <textarea name="textarea1" id="textarea1"></textarea><br />
    <input type="submit" value="submit" />
</form>
<br /><br />
<a href="page2.php">Go to page2</a>

page2.php

<?php
    session_start(); // needs to be before anything else on page to use $_SESSION
    // this page outputs the textarea1 from the session IF it exists
    $textarea1 = ""; // set var to avoid errors
    if(isset($_SESSION['textarea1'])){
        $textarea1 = $_SESSION['textarea1']
    }
?>
<textarea><?php echo $textarea1;?></textarea>

WARNING!!! - This contains no validation!!!

How about this solution?

static string CalcAge(DateTime birthDay)
{
    DateTime currentDate = DateTime.Now;         
    int approximateAge = currentDate.Year - birthDay.Year;
    int daysToNextBirthDay = (birthDay.Month * 30 + birthDay.Day) - 
        (currentDate.Month * 30 + currentDate.Day) ;

    if (approximateAge == 0 || approximateAge == 1)
    {                
        int month =  Math.Abs(daysToNextBirthDay / 30);
        int days = Math.Abs(daysToNextBirthDay % 30);

        if (month == 0)
            return "Your age is: " + daysToNextBirthDay + " days";

        return "Your age is: " + month + " months and " + days + " days"; ;
    }

    if (daysToNextBirthDay > 0)
        return "Your age is: " + --approximateAge + " Years";

    return "Your age is: " + approximateAge + " Years"; ;
}

This is just about the most bizarre query I've ever written, but I'm pretty sure it gets the "last 5" rows from a table without ordering:

select * 
from issues
where issueid not in (
    select top (
        (select count(*) from issues) - 5
    ) issueid
    from issues
)

Note that this makes use of SQL Server 2005's ability to pass a value into the "top" clause - it doesn't work on SQL Server 2000.

Could write a udf and take a value to tell it which day of the week should be 1 would look like this (drawing on answer from John to use MOD instead of CASE):

DROP FUNCTION IF EXISTS `reporting`.`udfDayOfWeek`;
DELIMITER |
CREATE FUNCTION `reporting`.`udfDayOfWeek` (
  _date DATETIME,
  _firstDay TINYINT
) RETURNS tinyint(4)
FUNCTION_BLOCK: BEGIN
  DECLARE _dayOfWeek, _offset TINYINT;
  SET _offset = 8 - _firstDay;
  SET _dayOfWeek = (DAYOFWEEK(_date) + _offset) MOD 7;
  IF _dayOfWeek = 0 THEN
    SET _dayOfWeek = 7;
  END IF;
  RETURN _dayOfWeek;
END FUNCTION_BLOCK

To call this function to give you the current day of week value when your week starts on a Tuesday for instance, you'd call:

SELECT udfDayOfWeek(NOW(), 3);

Nice thing about having it as a udf is you could also call it on a result set field like this:

SELECT
  udfDayOfWeek(p.SignupDate, 3) AS SignupDayOfWeek,
  p.FirstName,
  p.LastName
FROM Profile p;

I would style a link to look like a button, because that way there is a no-js fallback.

So this is how you could animate the jump using jquery. No-js fallback is a normal jump without animation.

Original example:

jsfiddle

$(document).ready(function() {_x000D_
  $(".jumper").on("click", function( e ) {_x000D_
_x000D_
    e.preventDefault();_x000D_
_x000D_
    $("body, html").animate({ _x000D_
      scrollTop: $( $(this).attr('href') ).offset().top _x000D_
    }, 600);_x000D_
_x000D_
  });_x000D_
});

#long {_x000D_
  height: 500px;_x000D_
  background-color: blue;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<!-- Links that trigger the jumping -->_x000D_
<a class="jumper" href="#pliip">Pliip</a>_x000D_
<a class="jumper" href="#ploop">Ploop</a>_x000D_
<div id="long">...</div>_x000D_
<!-- Landing elements -->_x000D_
<div id="pliip">pliip</div>_x000D_
<div id="ploop">ploop</div>

New example with actual button styles for the links, just to prove a point.

Everything is essentially the same, except that I changed the class .jumper to .button and I added css styling to make the links look like buttons.

Button styles example

I had the same error message. For me it was happening because I was trying to run the installer from the DVD rather than running the installer from Add/Remove programs.

As @kgr mentioned, MySQL 8.0.11 made some changes to the authentication method.

I've opened a phpMyAdmin bug report about this: https://github.com/phpmyadmin/phpmyadmin/issues/14220.

MySQL 8.0.4-rc was working fine for me, and I kind of think it's ridiculous for MySQL to make such a change in a patch level release.

You Can use Linq by Name Grouping

  var allEntries = from r in dt.AsEnumerable()
                            select r["Amount"];

using name space using System.Linq;

You can find the sample total,subtotal,grand total in datatable using c# at Myblog

In MySQL :-

RENAME TABLE `Stu Table` TO `Stu Table_10`

You may try this to execute a function inside your script

python -c "import sys; sys.path.append('/your/script/path'); import yourscript; yourscript.yourfunction()"

If you need a number greater than 999,999.00 you will have a problem.
These are only good for numbers less than 1 million, 1,000,000.
They only remove 1 or 2 commas.

Here the script that can remove up to 12 commas:

function uncomma(x) {
  var string1 = x;
  for (y = 0; y < 12; y++) {
    string1 = string1.replace(/\,/g, '');
  }
  return string1;
}

Modify that for loop if you need bigger numbers.

The best superuser role would be the root.The Syntax is:

use admin

db.createUser(
{
    user: "root",
    pwd: "password",
    roles: [ "root" ]
})

For more details look at built-in roles.

Hope this helps !!!

In Go, there is a general rule that syntax should not hide complex/costly operations. Converting a string to an interface{} is done in O(1) time. Converting a []string to an interface{} is also done in O(1) time since a slice is still one value. However, converting a []string to an []interface{} is O(n) time because each element of the slice must be converted to an interface{}.

The one exception to this rule is converting strings. When converting a string to and from a []byte or a []rune, Go does O(n) work even though conversions are "syntax".

There is no standard library function that will do this conversion for you. You could make one with reflect, but it would be slower than the three line option.

Example with reflection:

func InterfaceSlice(slice interface{}) []interface{} {
    s := reflect.ValueOf(slice)
    if s.Kind() != reflect.Slice {
        panic("InterfaceSlice() given a non-slice type")
    }

    // Keep the distinction between nil and empty slice input
    if s.IsNil() {
        return nil
    }

    ret := make([]interface{}, s.Len())

    for i:=0; i<s.Len(); i++ {
        ret[i] = s.Index(i).Interface()
    }

    return ret
}

Your best option though is just to use the lines of code you gave in your question:

b := make([]interface{}, len(a))
for i := range a {
    b[i] = a[i]
}

If you have a seeder in your database, run php artisan migrate:fresh --seed

Forming a XML file

XmlTextWriter xmlw = new XmlTextWriter(@"C:\WINDOWS\Temp\exm.xml",System.Text.Encoding.UTF8);
xmlw.WriteStartDocument();            
xmlw.WriteStartElement("examtimes");
xmlw.WriteStartElement("Starttime");
xmlw.WriteString(DateTime.Now.AddHours(0).ToString());
xmlw.WriteEndElement();
xmlw.WriteStartElement("Changetime");
xmlw.WriteString(DateTime.Now.AddHours(0).ToString());
xmlw.WriteEndElement();
xmlw.WriteStartElement("Endtime");
xmlw.WriteString(DateTime.Now.AddHours(1).ToString());
xmlw.WriteEndElement();
xmlw.WriteEndElement();
xmlw.WriteEndDocument();  
xmlw.Close();           

To edit the Xml nodes use the below code

XmlDocument doc = new XmlDocument(); 
doc.Load(@"C:\WINDOWS\Temp\exm.xml"); 
XmlNode root = doc.DocumentElement["Starttime"]; 
root.FirstChild.InnerText = "First"; 
XmlNode root1 = doc.DocumentElement["Changetime"]; 
root1.FirstChild.InnerText = "Second"; 
doc.Save(@"C:\WINDOWS\Temp\exm.xml"); 

Try this. It's C# code.

I found a problem in IE and Edge. Webkit browsers (Chrome, safari) seem to be more forgiving. When setting cookies, always set the "path" to something, because the default will be the page that set the cookie. So if you try to expire it on a different page without specifying the "path", the path won't match and it won't expire. The document.cookie value doesn't show the path or expiration for a cookie, so you can't derive where the cookie was set by looking at the value.

If you need to expire cookies from different pages, save the path of the setting page in the cookie value so you can pull it out later or always append "; path=/;" to the cookie value. Then it will expire from any page.

Try this one:

Sub clear_sht
  Dim sht As Worksheet
  Set sht = Worksheets(GENERATOR_SHT_NAME)
  col_cnt = sht.UsedRange.Columns.count
  If col_cnt = 0 Then
    col_cnt = 1
  End If

  sht.Range(sht.Cells(1, 1), sht.Cells(sht.UsedRange.Rows.count, col_cnt)).Clear
End Sub

this is my solution

JTextField username = new JTextField();
JTextField password = new JPasswordField();
Object[] message = {
    "Username:", username,
    "Password:", password
};

int option = JOptionPane.showConfirmDialog(null, message, "Login", JOptionPane.OK_CANCEL_OPTION);
if (option == JOptionPane.OK_OPTION) {
    if (username.getText().equals("h") && password.getText().equals("h")) {
        System.out.println("Login successful");
    } else {
        System.out.println("login failed");
    }
} else {
    System.out.println("Login canceled");
}

If you are trying to block all interaction with the page you might want to look at the jQuery BlockUI Plugin

In your template

template <void (*T)(int &)>
void doOperation()

The parameter T is a non-type template parameter. This means that the behaviour of the template function changes with the value of the parameter (which must be fixed at compile time, which function pointer constants are).

If you want somthing that works with both function objects and function parameters you need a typed template. When you do this, though, you also need to provide an object instance (either function object instance or a function pointer) to the function at run time.

template <class T>
void doOperation(T t)
{
  int temp=0;
  t(temp);
  std::cout << "Result is " << temp << std::endl;
}

There are some minor performance considerations. This new version may be less efficient with function pointer arguments as the particular function pointer is only derefenced and called at run time whereas your function pointer template can be optimized (possibly the function call inlined) based on the particular function pointer used. Function objects can often be very efficiently expanded with the typed template, though as the particular operator() is completely determined by the type of the function object.

I have encountered the same error while trying to execute a script file created in windows OS using textpad. so that one can select proper file format like unix/mac etc.. or recreate the script in linux iteself.

Just another example using HTML and CSS:

<div style="width: Auto; margin: 0 auto;">Hello</div>

Like I've written in a comment, this problem is probably related to this SO answer.

In short: there are multiple ways to verify the certificate. The verification used by OpenSSL is incompatible with the trusted root certificates you have on your system. OpenSSL is used by Python.

You could try to get the missing certificate for Verisign Class 3 Public Primary Certification Authority and then use the cafile option according to the Python documentation:

urllib2.urlopen(req, cafile="verisign.pem")

In addition to cookies and localStorage, there's at least one other place you can store "semi-persistent" client data: window.name. Any string value you assign to window.name will stay there until the window is closed.

To test it out, just open the console and type window.name = "foo", then refresh the page and type window.name; it should respond with foo.

This is a bit of a hack, but if you don't want cookies filled with unnecessary data being sent to the server with every request, and if you can't use localStorage for whatever reason (legacy clients), it may be an option to consider.

window.name has another interesting property: it's visible to windows served from other domains; it's not subject to the same-origin policy like nearly every other property of window. So, in addition to storing "semi-persistent" data there while the user navigates or refreshes the page, you can also use it for CORS-free cross-domain communication.

Note that window.name can only store strings, but with the wide availability of JSON, this shouldn't be much of an issue even for complex data.

Tried this in the console, and it works.

var aFileParts = ['<a id="a"><b id="b">hey!</b></a>'];
var oMyBlob = new Blob(aFileParts, {type : 'text/html'}); // the blob
window.open(URL.createObjectURL(oMyBlob));

you can go:

var cp = require('child_process');

and then:

cp.exec('./myScript.sh', function(err, stdout, stderr) {
  // handle err, stdout, stderr
});

to run a command in your $SHELL.
Or go

cp.spawn('./myScript.sh', [args], function(err, stdout, stderr) {
  // handle err, stdout, stderr
});

to run a file WITHOUT a shell.
Or go

cp.execFile();

which is the same as cp.exec() but doesn't look in the $PATH.

You can also go

cp.fork('myJS.js', function(err, stdout, stderr) {
  // handle err, stdout, stderr
});

to run a javascript file with node.js, but in a child process (for big programs).

EDIT

You might also have to access stdin and stdout with event listeners. e.g.:

var child = cp.spawn('./myScript.sh', [args]);
child.stdout.on('data', function(data) {
  // handle stdout as `data`
});

You could do, assuming you have an array with value and array length: arrayVal[i], arrayLength:

int sum = 0;
for (int i = 0; i < arrayLength; i++) {
    sum += arrayVal[i];
}

System.out.println("the sum is" + sum);

I hope this helps.

It's interesting that people always use 'real world problem' to make joke on the definition in theoretical science.

If set has order, you first need to figure out the following problems. If your list has duplicate elements, what should the order be when you turn it into a set? What is the order if we union two sets? What is the order if we intersect two sets with different order on the same elements?

Plus, set is much faster in searching for a particular key which is very good in sets operation (and that's why you need a set, but not list).

If you really care about the index, just keep it as a list. If you still want to do set operation on the elements in many lists, the simplest way is creating a dictionary for each list with the same keys in the set along with a value of list containing all the index of the key in the original list.

def indx_dic(l):
    dic = {}
    for i in range(len(l)):
        if l[i] in dic:
            dic.get(l[i]).append(i)
        else:
            dic[l[i]] = [i]
    return(dic)

a = [1,2,3,4,5,1,3,2]
set_a  = set(a)
dic_a = indx_dic(a)

print(dic_a)
# {1: [0, 5], 2: [1, 7], 3: [2, 6], 4: [3], 5: [4]}
print(set_a)
# {1, 2, 3, 4, 5}

Use array_values.

$myarray = array_values($myarray);

If you want to provide a timeout for a particular query, then CommandTimeout is the way forward.

Its usage is:

command.CommandTimeout = 60; //The time in seconds to wait for the command to execute. The default is 30 seconds.

For example if you have image in folder res/image.png you can write:

try
{
    ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
    InputStream input = classLoader.getResourceAsStream("image.png");
    // URL input = classLoader.getResource("image.png"); // <-- You can use URL class too.
    BufferedImage image = ImageIO.read(input);

    button.setIcon(new ImageIcon(image));
}
catch(IOException e)
{
    e.printStackTrace();
}

In one line:

try
{
    button.setIcon(new ImageIcon(ImageIO.read(Thread.currentThread().getContextClassLoader().getResourceAsStream("image.png"))));
}
catch(IOException e)
{
    e.printStackTrace();
}

If the image is bigger than button then it will not shown.

To merge the sets in the array Sets, you can do

var Sets = [set1, set2, set3];

var merged = new Set([].concat(...Sets.map(set => Array.from(set))));

It is slightly mysterious to me why the following, which should be equivalent, fails at least in Babel:

var merged = new Set([].concat(...Sets.map(Array.from)));

Here are couple more free tools that can be used for this. Both work as SSMS addins.

ApexSQL Search – 100% free - searches both schema and data in tables. Has couple more useful options such as dependency tracking…

SSMS Tools pack – free for all versions except SQL 2012 – doesn’t look as advanced as previous one but has a lot of other cool features.

x="Alpha_beta_Gamma"
is_uppercase_letter = True in map(lambda l: l.isupper(), x)
print is_uppercase_letter
>>>>True

So you can write it in 1 string

I had a similar problem:

module cv2 has no attribute "cv2.TrackerCSRT_create"

My Python version is 3.8.0 under Windows 10. The problem was the opencv version installation.

So I fixed this way (cmd prompt with administrator privileges):

1. Uninstalled opencv-python: pip uninstall opencv-python
2. Installed only opencv-contrib-python: pip install opencv-contrib-python

Anyway you can read the following guide:

https://github.com/skvark/opencv-python

You can easily iterate you collection. The example below is for the special Access TempVars collection, but works with any regular collection.

Dim tv As Long
For tv = 0 To TempVars.Count - 1
    Debug.Print TempVars(tv).Name, TempVars(tv).Value
Next tv

I had the exact same problem. I need the filename so to be able to upload it to a website.

It worked for me, if I changed the intent to PICK. This was tested in AVD for Android 4.4 and in AVD for Android 2.1.

Add permission READ_EXTERNAL_STORAGE :

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

Change the Intent :

Intent i = new Intent(
  Intent.ACTION_PICK,
  android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI
  );
startActivityForResult(i, 66453666);

/* OLD CODE
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(
  Intent.createChooser( intent, "Select Image" ),
  66453666
  );
*/

I did not have to change my code the get the actual path:

// Convert the image URI to the direct file system path of the image file
 public String mf_szGetRealPathFromURI(final Context context, final Uri ac_Uri )
 {
     String result = "";
     boolean isok = false;

     Cursor cursor = null;
      try { 
        String[] proj = { MediaStore.Images.Media.DATA };
        cursor = context.getContentResolver().query(ac_Uri,  proj, null, null, null);
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        result = cursor.getString(column_index);
        isok = true;
      } finally {
        if (cursor != null) {
          cursor.close();
        }
      }

      return isok ? result : "";
 }

I use ZF2 and work for me when replaced 'PHPUnit_Framework_TestCase' to '\PHPUnit\Framework\TestCase'

__block is a storage qualifier that can be used in two ways:

1. Marks that a variable lives in a storage that is shared between the lexical scope of the original variable and any blocks declared within that scope. And clang will generate a struct to represent this variable, and use this struct by reference(not by value).

2. In MRC, __block can be used to avoid retain object variables a block captures. Careful that this doesn't work for ARC. In ARC, you should use __weak instead.

You can refer to apple doc for detailed information.

1. Go to Build -> Generate Signed APK in Android Studio.
2. In the new window appeared, click on Create new... button.
3. Next enter details as like shown below and click OK -> Next.
4. Select the Build Type as release and click Finish button.
5. Wait until APK generated successfully message is displayed as like shown below.
6. Click on Show in Explorer to see the signed APK file.

I still remember the first weeks of my programming courses and I totally understand how you feel. Here is the code that solves your problem. In order to learn from this answer, try to run it adding several 'print' in the loop, so you can see the progress of the variables.

import java.util.*;
import java.lang.*;

public class foo
{

   public static void main(String[] args)
   { 
      double[] alpha = new double[50];
      int count = 0;

      for (int i=0; i<50; i++)
      {
          // System.out.print("variable i = " + i + "\n");
          if (i < 25)
          {
                alpha[i] = i*i;
          }
          else {
                alpha[i] = 3*i;
          }

          if (count < 10)
          {
            System.out.print(alpha[i]+ " "); 
          }  
          else {
            System.out.print("\n"); 
            System.out.print(alpha[i]+ " "); 
            count = 0;
          }

          count++;
      }

      System.out.print("\n"); 

    }
}

In my situation, the controller method was not made as async and the method called inside the controller method was async.

So I guess its important to use async/await all the way to top level to avoid issues like these.

You use a combination of CSS's transform (with vendor prefixes as necessary) and transform-origin, like this: (also on jsFiddle)

var angle = 0,_x000D_
  img = document.getElementById('container');_x000D_
document.getElementById('button').onclick = function() {_x000D_
  angle = (angle + 90) % 360;_x000D_
  img.className = "rotate" + angle;_x000D_
}

#container {_x000D_
  width: 820px;_x000D_
  height: 100px;_x000D_
  overflow: hidden;_x000D_
}_x000D_
#container.rotate90,_x000D_
#container.rotate270 {_x000D_
  width: 100px;_x000D_
  height: 820px_x000D_
}_x000D_
#image {_x000D_
  transform-origin: top left;_x000D_
  /* IE 10+, Firefox, etc. */_x000D_
  -webkit-transform-origin: top left;_x000D_
  /* Chrome */_x000D_
  -ms-transform-origin: top left;_x000D_
  /* IE 9 */_x000D_
}_x000D_
#container.rotate90 #image {_x000D_
  transform: rotate(90deg) translateY(-100%);_x000D_
  -webkit-transform: rotate(90deg) translateY(-100%);_x000D_
  -ms-transform: rotate(90deg) translateY(-100%);_x000D_
}_x000D_
#container.rotate180 #image {_x000D_
  transform: rotate(180deg) translate(-100%, -100%);_x000D_
  -webkit-transform: rotate(180deg) translate(-100%, -100%);_x000D_
  -ms-transform: rotate(180deg) translateX(-100%, -100%);_x000D_
}_x000D_
#container.rotate270 #image {_x000D_

  -webkit-transform: rotate(270deg) translateX(-100%);_x000D_
  -ms-transform: rotate(270deg) translateX(-100%);_x000D_
}

The browser will execute the scripts in the order it finds them. If you call an external script, it will block the page until the script has been loaded and executed.

To test this fact:

// file: test.php
sleep(10);
die("alert('Done!');");

// HTML file:
<script type="text/javascript" src="test.php"></script>

Dynamically added scripts are executed as soon as they are appended to the document.

To test this fact:

<!DOCTYPE HTML>
<html>
<head>
    <title>Test</title>
</head>
<body>
    <script type="text/javascript">
        var s = document.createElement('script');
        s.type = "text/javascript";
        s.src = "link.js"; // file contains alert("hello!");
        document.body.appendChild(s);
        alert("appended");
    </script>
    <script type="text/javascript">
        alert("final");
    </script>
</body>
</html>

Order of alerts is "appended" -> "hello!" -> "final"

If in a script you attempt to access an element that hasn't been reached yet (example: <script>do something with #blah</script><div id="blah"></div>) then you will get an error.

Overall, yes you can include external scripts and then access their functions and variables, but only if you exit the current <script> tag and start a new one.

Use the -isEqualToString: method to compare the value of two strings. Using the C == operator will simply compare the addresses of the objects.

if ([category isEqualToString:@"Some String"])
{
    // Do stuff...
}

I spent half a day searching for answers to an identical "Illegal mix of collations" error with conflicts between utf8_unicode_ci and utf8_general_ci.

I found that some columns in my database were not specifically collated utf8_unicode_ci. It seems mysql implicitly collated these columns utf8_general_ci.

Specifically, running a 'SHOW CREATE TABLE table1' query outputted something like the following:

| table1 | CREATE TABLE `table1` (
`id` int(11) NOT NULL,
`col1` varchar(4) CHARACTER SET utf8 NOT NULL,
`col2` int(11) NOT NULL,
PRIMARY KEY (`col1`,`col2`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci |

Note the line 'col1' varchar(4) CHARACTER SET utf8 NOT NULL does not have a collation specified. I then ran the following query:

ALTER TABLE table1 CHANGE col1 col1 VARCHAR(4) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL;

This solved my "Illegal mix of collations" error. Hope this might help someone else out there.

First Google hit says:

this is usually a mismatch in the client/server bindings, where the message version in the service uses SOAP 1.2 (which expects application/soap+xml) and the version in the client uses SOAP 1.1 (which sends text/xml). WSHttpBinding uses SOAP 1.2, BasicHttpBinding uses SOAP 1.1.

It usually seems to be a wsHttpBinding on one side and a basicHttpBinding on the other.

Smart pointers will clean themselves up after they go out of scope (thereby removing fear of most memory leaks). Shared pointers are smart pointers that keep a count of how many instances of the pointer exist, and only clean up the memory when the count reaches zero. In general, only use shared pointers (but be sure to use the correct kind--there is a different one for arrays). They have a lot to do with RAII.

To run the spring-boot application, need to follow some step.

1. Maven setup (ignore if already setup):

   a. Install maven from https://maven.apache.org/download.cgi

   b. Unzip maven and keep in C drive (you can keep any location. Path location will be changed accordingly).

   c. Set MAVEN_HOME in system variable.

   d. Set path for maven

2. Add Maven Plugin to POM.XML

   <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build>

3. Build Spring Boot Project with Maven

      maven package
   

   or

        mvn install / mvn clean install
   

4. Run Spring Boot app using Maven:

       mvn spring-boot:run
   

5. [optional] Run Spring Boot app with java -jar command

        java -jar target/mywebserviceapp-0.0.1-SNAPSHOT.jar

You can use the usual Python package structure to divide your App into multiple modules, see the Flask docs.

However,

Flask uses a concept of blueprints for making application components and supporting common patterns within an application or across applications.

You can create a sub-component of your app as a Blueprint in a separate file:

simple_page = Blueprint('simple_page', __name__, template_folder='templates')
@simple_page.route('/<page>')
def show(page):
    # stuff

And then use it in the main part:

from yourapplication.simple_page import simple_page

app = Flask(__name__)
app.register_blueprint(simple_page)

Blueprints can also bundle specific resources: templates or static files. Please refer to the Flask docs for all the details.

According to the grammar in the CSP spec, you need to specify schemes as scheme:, not just scheme. So, you need to change the image source directive to:

img-src 'self' data:;

No, there is no such printf width specifier to print floating-point with maximum precision. Let me explain why.

The maximum precision of float and double is variable, and dependent on the actual value of the float or double.

Recall float and double are stored in sign.exponent.mantissa format. This means that there are many more bits used for the fractional component for small numbers than for big numbers.

For example, float can easily distinguish between 0.0 and 0.1.

float r = 0;
printf( "%.6f\n", r ) ; // 0.000000
r+=0.1 ;
printf( "%.6f\n", r ) ; // 0.100000

But float has no idea of the difference between 1e27 and 1e27 + 0.1.

r = 1e27;
printf( "%.6f\n", r ) ; // 999999988484154753734934528.000000
r+=0.1 ;
printf( "%.6f\n", r ) ; // still 999999988484154753734934528.000000

This is because all the precision (which is limited by the number of mantissa bits) is used up for the large part of the number, left of the decimal.

The %.f modifier just says how many decimal values you want to print from the float number as far as formatting goes. The fact that the accuracy available depends on the size of the number is up to you as the programmer to handle. printf can't/doesn't handle that for you.

If a member is a Array it will be a little bit complex than the normal is:

class C
{
    static const int ARRAY[10];

GZIP + Base64

The length of the string in a Base64 format is greater then original: 133% on average. So it makes sense to first compress it with GZIP, and then encode to Base64. It gives a reduction of up to 77% for strings greater than 200 characters and more. Example:

public static void main(String[] args) throws IOException {
    byte[] original = randomString(100).getBytes(StandardCharsets.UTF_8);

    byte[] base64 = encodeToBase64(original);
    byte[] gzipToBase64 = encodeToBase64(encodeToGZIP(original));

    byte[] fromBase64 = decodeFromBase64(base64);
    byte[] fromBase64Gzip = decodeFromGZIP(decodeFromBase64(gzipToBase64));

    // test
    System.out.println("Original: " + original.length + " bytes, 100%");
    System.out.println("Base64: " + base64.length + " bytes, "
            + (base64.length * 100 / original.length) + "%");
    System.out.println("GZIP+Base64: " + gzipToBase64.length + " bytes, "
            + (gzipToBase64.length * 100 / original.length) + "%");

    //Original: 3700 bytes, 100%
    //Base64: 4936 bytes, 133%
    //GZIP+Base64: 2868 bytes, 77%

    System.out.println(Arrays.equals(original, fromBase64)); // true
    System.out.println(Arrays.equals(original, fromBase64Gzip)); // true
}

public static byte[] decodeFromBase64(byte[] arr) {
    return Base64.getDecoder().decode(arr);
}

public static byte[] encodeToBase64(byte[] arr) {
    return Base64.getEncoder().encode(arr);
}

public static byte[] decodeFromGZIP(byte[] arr) throws IOException {
    ByteArrayInputStream bais = new ByteArrayInputStream(arr);
    GZIPInputStream gzip = new GZIPInputStream(bais);
    return gzip.readAllBytes();
}

public static byte[] encodeToGZIP(byte[] arr) throws IOException {
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    GZIPOutputStream gzip = new GZIPOutputStream(baos);
    gzip.write(arr);
    gzip.finish();
    return baos.toByteArray();
}

public static String randomString(int count) {
    StringBuilder str = new StringBuilder();
    for (int i = 0; i < count; i++) {
        str.append(" ").append(UUID.randomUUID().toString());
    }
    return str.toString();
}

If you just want to pass a std::string to a function that needs const char* you can use

std::string str;
const char * c = str.c_str();

If you want to get a writable copy, like char *, you can do that with this:

std::string str;
char * writable = new char[str.size() + 1];
std::copy(str.begin(), str.end(), writable);
writable[str.size()] = '\0'; // don't forget the terminating 0

// don't forget to free the string after finished using it
delete[] writable;

Edit: Notice that the above is not exception safe. If anything between the new call and the delete call throws, you will leak memory, as nothing will call delete for you automatically. There are two immediate ways to solve this.

boost::scoped_array

boost::scoped_array will delete the memory for you upon going out of scope:

std::string str;
boost::scoped_array<char> writable(new char[str.size() + 1]);
std::copy(str.begin(), str.end(), writable.get());
writable[str.size()] = '\0'; // don't forget the terminating 0

// get the char* using writable.get()

// memory is automatically freed if the smart pointer goes 
// out of scope

std::vector

This is the standard way (does not require any external library). You use std::vector, which completely manages the memory for you.

std::string str;
std::vector<char> writable(str.begin(), str.end());
writable.push_back('\0');

// get the char* using &writable[0] or &*writable.begin()

sb.Append(Environment.Newline);
sb.Append("\t");

In case if you are using WPF application using PRISM framework then configuration should exist in your start up project (i.e. in the project where your bootstrapper resides.)

In short just remove it from the class library and put into a start up project.

Don't use more commands than necessary, leave away tail, grep and cut. You can do this with only (a simple) awk

PS: giving a block-size en print only de persentage is a bit silly ;-) So leave also away the "-B MB"

df . |awk -F'[multiple field seperators]' '$NF=="Last field must be exactly --> mounted patition" {print $(NF-number from last field)}'

in your case, use:

df . |awk -F'[ %]' '$NF=="/" {print $(NF-2)}'

output: 81

If you want to show the percent symbol, you can leave the -F'[ %]' away and your print field will move 1 field further back

df . |awk '$NF=="/" {print $(NF-1)}'

output: 81%

Single file:

String filePath = "/absolute/path/file1.txt";
String zipPath = "/absolute/path/output.zip";

try (ZipOutputStream zipOut = new ZipOutputStream(new FileOutputStream(zipPath))) {
    File fileToZip = new File(filePath);
    zipOut.putNextEntry(new ZipEntry(fileToZip.getName()));
    Files.copy(fileToZip.toPath(), zipOut);
}

Multiple files:

List<String> filePaths = Arrays.asList("/absolute/path/file1.txt", "/absolute/path/file2.txt");
String zipPath = "/absolute/path/output.zip";

try (ZipOutputStream zipOut = new ZipOutputStream(new FileOutputStream(zipPath))) {
    for (String filePath : filePaths) {
        File fileToZip = new File(filePath);
        zipOut.putNextEntry(new ZipEntry(fileToZip.getName()));
        Files.copy(fileToZip.toPath(), zipOut);
    }
}

The most important part is the concepts. Once you understand how the building blocks work, differences in syntax amount to little more than mild dialects. A layer on top of your regular expression engine's syntax is the syntax of the programming language you're using. Languages such as Perl remove most of this complication, but you'll have to keep in mind other considerations if you're using regular expressions in a C program.

If you think of regular expressions as building blocks that you can mix and match as you please, it helps you learn how to write and debug your own patterns but also how to understand patterns written by others.

Start simple

Conceptually, the simplest regular expressions are literal characters. The pattern N matches the character 'N'.

Regular expressions next to each other match sequences. For example, the pattern Nick matches the sequence 'N' followed by 'i' followed by 'c' followed by 'k'.

If you've ever used grep on Unix—even if only to search for ordinary looking strings—you've already been using regular expressions! (The re in grep refers to regular expressions.)

Order from the menu

Adding just a little complexity, you can match either 'Nick' or 'nick' with the pattern [Nn]ick. The part in square brackets is a character class, which means it matches exactly one of the enclosed characters. You can also use ranges in character classes, so [a-c] matches either 'a' or 'b' or 'c'.

The pattern . is special: rather than matching a literal dot only, it matches any character^†. It's the same conceptually as the really big character class [-.?+%$A-Za-z0-9...].

Think of character classes as menus: pick just one.

Helpful shortcuts

Using . can save you lots of typing, and there are other shortcuts for common patterns. Say you want to match a digit: one way to write that is [0-9]. Digits are a frequent match target, so you could instead use the shortcut \d. Others are \s (whitespace) and \w (word characters: alphanumerics or underscore).

The uppercased variants are their complements, so \S matches any non-whitespace character, for example.

Once is not enough

From there, you can repeat parts of your pattern with quantifiers. For example, the pattern ab?c matches 'abc' or 'ac' because the ? quantifier makes the subpattern it modifies optional. Other quantifiers are

• * (zero or more times)
• + (one or more times)
• {n} (exactly n times)
• {n,} (at least n times)
• {n,m} (at least n times but no more than m times)

Putting some of these blocks together, the pattern [Nn]*ick matches all of

• ick
• Nick
• nick
• Nnick
• nNick
• nnick
• (and so on)

The first match demonstrates an important lesson: * always succeeds! Any pattern can match zero times.

A few other useful examples:

• [0-9]+ (and its equivalent \d+) matches any non-negative integer
• \d{4}-\d{2}-\d{2} matches dates formatted like 2019-01-01

Grouping

A quantifier modifies the pattern to its immediate left. You might expect 0abc+0 to match '0abc0', '0abcabc0', and so forth, but the pattern immediately to the left of the plus quantifier is c. This means 0abc+0 matches '0abc0', '0abcc0', '0abccc0', and so on.

To match one or more sequences of 'abc' with zeros on the ends, use 0(abc)+0. The parentheses denote a subpattern that can be quantified as a unit. It's also common for regular expression engines to save or "capture" the portion of the input text that matches a parenthesized group. Extracting bits this way is much more flexible and less error-prone than counting indices and substr.

Alternation

Earlier, we saw one way to match either 'Nick' or 'nick'. Another is with alternation as in Nick|nick. Remember that alternation includes everything to its left and everything to its right. Use grouping parentheses to limit the scope of |, e.g., (Nick|nick).

For another example, you could equivalently write [a-c] as a|b|c, but this is likely to be suboptimal because many implementations assume alternatives will have lengths greater than 1.

Escaping

Although some characters match themselves, others have special meanings. The pattern \d+ doesn't match backslash followed by lowercase D followed by a plus sign: to get that, we'd use \\d\+. A backslash removes the special meaning from the following character.

Greediness

Regular expression quantifiers are greedy. This means they match as much text as they possibly can while allowing the entire pattern to match successfully.

For example, say the input is

"Hello," she said, "How are you?"

You might expect ".+" to match only 'Hello,' and will then be surprised when you see that it matched from 'Hello' all the way through 'you?'.

To switch from greedy to what you might think of as cautious, add an extra ? to the quantifier. Now you understand how \((.+?)\), the example from your question works. It matches the sequence of a literal left-parenthesis, followed by one or more characters, and terminated by a right-parenthesis.

If your input is '(123) (456)', then the first capture will be '123'. Non-greedy quantifiers want to allow the rest of the pattern to start matching as soon as possible.

(As to your confusion, I don't know of any regular-expression dialect where ((.+?)) would do the same thing. I suspect something got lost in transmission somewhere along the way.)

Anchors

Use the special pattern ^ to match only at the beginning of your input and $ to match only at the end. Making "bookends" with your patterns where you say, "I know what's at the front and back, but give me everything between" is a useful technique.

Say you want to match comments of the form

-- This is a comment --

you'd write ^--\s+(.+)\s+--$.

Build your own

Regular expressions are recursive, so now that you understand these basic rules, you can combine them however you like.

Footnote

†: The statement above that . matches any character is a simplification for pedagogical purposes that is not strictly true. Dot matches any character except newline, "\n", but in practice you rarely expect a pattern such as .+ to cross a newline boundary. Perl regexes have a /s switch and Java Pattern.DOTALL, for example, to make . match any character at all. For languages that don't have such a feature, you can use something like [\s\S] to match "any whitespace or any non-whitespace", in other words anything.

My workmates and I have different Gemfile.lock, because we use different platforms, windows and mac, and our server is linux.

We decide to remove Gemfile.lock in repo and create Gemfile.lock.server in git repo, just like database.yml. Then before deploy it on server, we copy Gemfile.lock.server to Gemfile.lock on server using cap deploy hook

Static blocks are used for initializaing the code and will be executed when JVM loads the class.Refer to the below link which gives the detailed explanation. http://www.jusfortechies.com/java/core-java/static-blocks.php

To append a file use >>

echo "hello world"  >> read.txt   
cat read.txt     
echo "hello siva" >> read.txt   
cat read.txt

then the output should be

hello world   # from 1st echo command
hello world   # from 2nd echo command
hello siva

To overwrite a file use >

echo "hello tom" > read.txt
cat read.txt  

then the out put is

hello tom

Maybe I misunderstand the question but if you want to convert the groupby back to a dataframe you can use .to_frame(). I wanted to reset the index when I did this so I included that part as well.

example code unrelated to question

df = df['TIME'].groupby(df['Name']).min()
df = df.to_frame()
df = df.reset_index(level=['Name',"TIME"])

Bluetooth devices can operate in both classic and LE mode at the same time. Sometimes they use a different MAC address depending on which way you are connecting. Calling socket.connect() is using Bluetooth Classic, so you have to make sure the device you got when you scanned was really a classic device.

It's easy to filter for only Classic devices, however:

if(BluetoothDevice.DEVICE_TYPE_LE == device.getType()){ //socket.connect() }

Without this check, it's a race condition as to whether a hybrid scan will give you the Classic device or the BLE device first. It may appear as intermittent inability to connect, or as certain devices being able to connect reliably while others seemingly never can.

To get e.g the value from column 'test' and row 1 it works like

df[['test']].values[0][0]

as only df[['test']].values[0] gives back a array

If anybody else had a problem with best answer's solution (including disabling foreign keys), here is another solution from me:

-- CLEAN DB
USE [DB_NAME]
    EXEC sp_MSForEachTable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL'
    EXEC sp_MSForEachTable 'DELETE FROM ?'

    DECLARE @Sql NVARCHAR(500) DECLARE @Cursor CURSOR
    SET @Cursor = CURSOR FAST_FORWARD FOR

    SELECT DISTINCT sql = 'ALTER TABLE [' + tc2.TABLE_NAME + '] DROP [' + rc1.CONSTRAINT_NAME + ']'
    FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS rc1
    LEFT JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS tc2 ON tc2.CONSTRAINT_NAME =rc1.CONSTRAINT_NAME
    OPEN @Cursor FETCH NEXT FROM @Cursor INTO @Sql
    WHILE (@@FETCH_STATUS = 0)
      BEGIN
        Exec SP_EXECUTESQL @Sql
        FETCH NEXT 
        FROM @Cursor INTO @Sql
      END
    CLOSE @Cursor DEALLOCATE @Cursor
    GO

    EXEC sp_MSForEachTable 'DROP TABLE ?'
    GO

    EXEC sp_MSForEachTable 'ALTER TABLE ? WITH CHECK CHECK CONSTRAINT ALL'

For workdays, Monday to Friday, you can do it with a single SELECT, like this:

DECLARE @StartDate DATETIME
DECLARE @EndDate DATETIME
SET @StartDate = '2008/10/01'
SET @EndDate = '2008/10/31'


SELECT
   (DATEDIFF(dd, @StartDate, @EndDate) + 1)
  -(DATEDIFF(wk, @StartDate, @EndDate) * 2)
  -(CASE WHEN DATENAME(dw, @StartDate) = 'Sunday' THEN 1 ELSE 0 END)
  -(CASE WHEN DATENAME(dw, @EndDate) = 'Saturday' THEN 1 ELSE 0 END)

If you want to include holidays, you have to work it out a bit...

You got an extra } to many as seen below:

var nav = document.getElementsByClassName('nav-coll');
for (var i = 0; i < button.length; i++) {
    nav[i].addEventListener('click',function(){
            console.log('haha');
        } // <-- REMOVE THIS :)
    }, false);
};

A very good tool for those things is jsFiddle. I have created a fiddle with your invalid code and when clicking the TidyUp button it formats your code which makes it clearer if there are any possible mistakes with missing braces.

DEMO - Your code in a fiddle, have a play :)

If you are using Java 8 then you can do this easier with CompletableFuture and CompletableFuture.allOf, which applies the callback only after all supplied CompletableFutures are done.

// Waits for *all* futures to complete and returns a list of results.
// If *any* future completes exceptionally then the resulting future will also complete exceptionally.

i know this is way too late. but i had the same requirement. i solved like this

<android.support.v7.widget.CardView
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:cardUseCompatPadding="true"
app:cardElevation="4dp"
app:cardCornerRadius="3dp" >

<!-- put whatever you want -->

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

you need to add dependency:

compile 'com.android.support:cardview-v7:25.0.1'

For http/https proxy with or without authentication:

Run one of the following commands in cmd.exe

set http_proxy=http://your_proxy:your_port
set http_proxy=http://username:password@your_proxy:your_port
set https_proxy=https://your_proxy:your_port
set https_proxy=https://username:password@your_proxy:your_port

Assuming your script is something like the below snippet and named testargs.ps1

param ([string]$w)
Write-Output $w

You can call this at the commandline as:

PowerShell.Exe -File C:\scripts\testargs.ps1 "Test String"

This will print "Test String" (w/o quotes) at the console. "Test String" becomes the value of $w in the script.

I know I'm late to the party but I find the zerofill is helpful for boolean representations of TINYINT(1). Null doesn't always mean False, sometimes you don't want it to. By zerofilling a tinyint, you're effectively converting those values to INT and removing any confusion ur application may have upon interaction. Your application can then treat those values in a manner similar to the primitive datatype True = Not(0)

If you found authentication error problem when you entered correct password and username it's git problem. To solves this problem when you are installing the git in your machine uncheck the enable git credential manager

You are experiencing this issue for two reasons.

• The JPQL Query is not valid.
• You have not created an association between your entities that the underlying JPQL query can utilize.

When performing a join in JPQL you must ensure that an underlying association between the entities attempting to be joined exists. In your example, you are missing an association between the User and Area entities. In order to create this association we must add an Area field within the User class and establish the appropriate JPA Mapping. I have attached the source for User below. (Please note I moved the mappings to the fields)

User.java

@Entity
@Table(name="user")
public class User {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="iduser")
    private Long idUser;

    @Column(name="user_name")
    private String userName;

    @OneToOne()
    @JoinColumn(name="idarea")
    private Area area;

    public Long getIdUser() {
        return idUser;
    }

    public void setIdUser(Long idUser) {
        this.idUser = idUser;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public Area getArea() {
        return area;
    }

    public void setArea(Area area) {
        this.area = area;
    }
}

Once this relationship is established you can reference the area object in your @Query declaration. The query specified in your @Query annotation must follow proper syntax, which means you should omit the on clause. See the following:

@Query("select u.userName from User u inner join u.area ar where ar.idArea = :idArea")

While looking over your question I also made the relationship between the User and Area entities bidirectional. Here is the source for the Area entity to establish the bidirectional relationship.

Area.java

@Entity
@Table(name = "area")
public class Area {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="idarea")
    private Long idArea;

    @Column(name="area_name")
    private String areaName;

    @OneToOne(fetch=FetchType.LAZY, mappedBy="area")
    private User user;

    public Long getIdArea() {
        return idArea;
    }

    public void setIdArea(Long idArea) {
        this.idArea = idArea;
    }

    public String getAreaName() {
        return areaName;
    }

    public void setAreaName(String areaName) {
        this.areaName = areaName;
    }

    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }
}

In all schemas:

=> \dt *.*

In a particular schema:

=> \dt public.*

It is possible to use regular expressions with some restrictions

\dt (public|s).(s|t)
       List of relations
 Schema | Name | Type  | Owner 
--------+------+-------+-------
 public | s    | table | cpn
 public | t    | table | cpn
 s      | t    | table | cpn

Advanced users can use regular-expression notations such as character classes, for example [0-9] to match any digit. All regular expression special characters work as specified in Section 9.7.3, except for . which is taken as a separator as mentioned above, * which is translated to the regular-expression notation .*, ? which is translated to ., and $ which is matched literally. You can emulate these pattern characters at need by writing ? for ., (R+|) for R*, or (R|) for R?. $ is not needed as a regular-expression character since the pattern must match the whole name, unlike the usual interpretation of regular expressions (in other words, $ is automatically appended to your pattern). Write * at the beginning and/or end if you don't wish the pattern to be anchored. Note that within double quotes, all regular expression special characters lose their special meanings and are matched literally. Also, the regular expression special characters are matched literally in operator name patterns (i.e., the argument of \do).

Python lists are mutable objects and here:

plot_data = [[]] * len(positions) 

you are repeating the same list len(positions) times.

>>> plot_data = [[]] * 3
>>> plot_data
[[], [], []]
>>> plot_data[0].append(1)
>>> plot_data
[[1], [1], [1]]
>>> 

Each list in your list is a reference to the same object. You modify one, you see the modification in all of them.

If you want different lists, you can do this way:

plot_data = [[] for _ in positions]

for example:

>>> pd = [[] for _ in range(3)]
>>> pd
[[], [], []]
>>> pd[0].append(1)
>>> pd
[[1], [], []]

Free, and no external DLL files. Everything is in one CS file. One download is just the CS file, another download is a very easy to understand example. Just tried it today and I can't believe how simple the setup was. It worked on first try, no errors, no nothing.

https://github.com/jaime-olivares/zipstorer

use this line, this worked for me

mongoose.set('useUnifiedTopology', true);

You can do this:

<img src="your image" style="transform:rotate(90deg);">

it is much easier.
