Programs & Examples On #Fabric

Downgrading the version of Gradle worked for me:

classpath 'com.android.tools.build:gradle:3.2.0'

My scenario:

old Kotlin dataclass:

data class AddHotelParams(val destination: Place?, val checkInDate: LocalDate,
                      val checkOutDate: LocalDate?): JsonObject

new Kotlin dataclass:

data class AddHotelParams(val destination: Place?, val checkInDate: LocalDate,
                      val checkOutDate: LocalDate?, val roundTrip: Boolean): JsonObject

The problem was that I forgot to change the object initialization in some parts of the code. I got a generic "compileInternalDebugKotlin" error instead of being told where I needed to change the initialization.

changing initialization to all parts of the code resolved the error.

In my case, I just had to do

1. Click Build
2. Click Make Project

It all then went fine. I still have no clue what happened.

Thing that worked for me.

1. Go to android folder of your app.
2. Run ./gradlew clean

Actually it is not the matter of the primarycolortext, upgrading or downgrading the dependencies.This problem will likely occur when the version of your appcompat library and design support library doesn't match.

Example of matching condition

compile 'com.android.support:appcompat-v7:23.1.1' // appcompat library
compile 'com.android.support:design:23.1.1'       //design support library

Partial dependence is solved for arriving to a relation in 2NF but 2NF is a "stepping stone" (C. Date) for solving any transitive dependency and arriving to a relation in 3NF (which is the operational target). However, the most interested thing on partial dependence is that it is a particular case of the own transitive dependency. This was demostrated by P. A. Berstein in 1976: IF {(x•y)?z but y?z} THEN {(x•y)?y & y?z}. The 3NF synthesizer algorithm of Berstein does not need doing distintions among these two type of relational defects.

You are encoding to UTF-8, then re-encoding to UTF-8. Python can only do this if it first decodes again to Unicode, but it has to use the default ASCII codec:

>>> u'ñ'
u'\xf1'
>>> u'ñ'.encode('utf8')
'\xc3\xb1'
>>> u'ñ'.encode('utf8').encode('utf8')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 0: ordinal not in range(128)

Don't keep encoding; leave encoding to UTF-8 to the last possible moment instead. Concatenate Unicode values instead.

You can use str.join() (or, rather, unicode.join()) here to concatenate the three values with dashes in between:

nombre = u'-'.join(fabrica, sector, unidad)
return nombre.encode('utf-8')

but even encoding here might be too early.

Rule of thumb: decode the moment you receive the value (if not Unicode values supplied by an API already), encode only when you have to (if the destination API does not handle Unicode values directly).

Below worked for me:

When you come to Server Configuration Screen, Change the Account Name of Database Engine Service to NT AUTHORITY\NETWORK SERVICE and continue installation and it will successfully install all components without any error. - See more at: https://superpctricks.com/sql-install-error-database-engine-recovery-handle-failed/

I also hit this error…

The installation msi will try to create a new task in the Windows Task scheduler to remind you to give customer feedback. This install step executes regardless of whether you do or do not click the check box to participate in customer feedback. In many corporate environments (including mine) creating new windows tasks is denied to all but domain administrators. As a result, running as a local admin is not sufficient and the entire installation fails when adding the task returns “access denied”. This shows up in the install log as a 1603.

The only workaround we could find was to manually pull all the files out of the msi, remove the “add schedule task” from the install script, and then create a new msi. After that one line change, it worked fine.

I had a similar problem. I tried this:

    pip install -U -r requirements.txt

(-U = update if it had already installed)

But the problem continued. I realized that some of generic libraries for development were missed.

    sudo apt-get install libtiff5-dev libjpeg8-dev zlib1g-dev liblcms2-dev libwebp-dev tcl8.6-dev tk8.6-dev python-tk

I don't know if this would help you.

You didn't provide many relevant details so I will guess that you called getInvoice and then you used result object to set some values and call save with assumption that your object changes will be saved.

However, persist operation is intended for brand new transient objects and it fails if id is already assigned. In your case you probably want to call saveOrUpdate instead of persist.

You can find some discussion and references here "detached entity passed to persist error" with JPA/EJB code

I used these options to convert to the H.264/AAC .mp4 format for HTML5 playback (I think it may help other guys with this problem in some way):

ffmpeg -i input.flv -vcodec mpeg4 -acodec aac output.mp4

UPDATE

As @LordNeckbeard mentioned, the previous line will produce MPEG-4 Part 2 (back in 2012 that worked somehow, I don't remember/understand why). Use the libx264 encoder to produce the proper video with H.264/AAC. To test the output file you can just drag it to a browser window and it should playback just fine.

ffmpeg -i input.flv -vcodec libx264 -acodec aac output.mp4

Matt Ball answered it correctly. I would say about it with examples.

Consider running a program compiled in Turbo-Borland C/C++ (version 3.1 from the year 1991) compiler and let it run under a 32-bit version of windows like Win 98/2000 etc.

It's a 16-bit compiler. And you will see all your programs have 16-bit pointers. Why is it so when your OS is 32bit? Because your compiler has set up the execution environment of 16 bit and the 32-bit version of OS supported it.

What is commonly called as JRE (Java Runtime Environment) provides a Java program with all the resources it may need to execute.

Actually, runtime environment is brain product of idea of Virtual Machines. A virtual machine implements the raw interface between hardware and what a program may need to execute. The runtime environment adopts these interfaces and presents them for the use of the programmer. A compiler developer would need these facilities to provide an execution environment for its programs.

For batch processing files in folder:

for i in *.wav; do ffmpeg -i "$i" -f mp3 "${i%}.mp3"; done

This script converts all "wav" files in folder to mp3 files and adds mp3 extension

ffmpeg have to be installed. (See other answers)

On submitting, you would get an array as if created like this:

$_POST['topdiameter'] = array( 'first value', 'second value' );
$_POST['bottomdiameter'] = array( 'first value', 'second value' );

However, I would suggest changing your form names to this format instead:

name="diameters[0][top]"
name="diameters[0][bottom]"
name="diameters[1][top]"
name="diameters[1][bottom]"
...

Using that format, it's much easier to loop through the values.

if ( isset( $_POST['diameters'] ) )
{
    echo '<table>';
    foreach ( $_POST['diameters'] as $diam )
    {
        // here you have access to $diam['top'] and $diam['bottom']
        echo '<tr>';
        echo '  <td>', $diam['top'], '</td>';
        echo '  <td>', $diam['bottom'], '</td>';
        echo '</tr>';
    }
    echo '</table>';
}

If you are using Spring 3.1 and above, you can use something like...

@Configuration
@PropertySource("classpath:foo.properties")
public class PropertiesWithJavaConfig {

@Bean
public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
  return new PropertySourcesPlaceholderConfigurer();
}
}

You can also go by the xml configuration like...

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="

  http://www.springframework.org/schema/context 
  http://www.springframework.org/schema/context/spring-context-3.2.xsd">

  <context:property-placeholder location="classpath:foo.properties" />

  </beans>

In earlier versions.

HTTPS proxy doesn't make sense because you can't terminate your HTTP connection at the proxy for security reasons. With your trust policy, it might work if the proxy server has a HTTPS port. Your error is caused by connecting to HTTP proxy port with HTTPS.

You can connect through a proxy using SSL tunneling (many people call that proxy) using proxy CONNECT command. However, Java doesn't support newer version of proxy tunneling. In that case, you need to handle the tunneling yourself. You can find sample code here,

http://www.javaworld.com/javaworld/javatips/jw-javatip111.html

EDIT: If you want defeat all the security measures in JSSE, you still need your own TrustManager. Something like this,

 public SSLTunnelSocketFactory(String proxyhost, String proxyport){
      tunnelHost = proxyhost;
      tunnelPort = Integer.parseInt(proxyport);
      dfactory = (SSLSocketFactory)sslContext.getSocketFactory();
 }

 ...

 connection.setSSLSocketFactory( new SSLTunnelSocketFactory( proxyHost, proxyPort ) );
 connection.setDefaultHostnameVerifier( new HostnameVerifier()
 {
    public boolean verify( String arg0, SSLSession arg1 )
    {
        return true;
    }
 }  );

EDIT 2: I just tried my program I wrote a few years ago using SSLTunnelSocketFactory and it doesn't work either. Apparently, Sun introduced a new bug sometime in Java 5. See this bug report,

http://bugs.sun.com/view_bug.do?bug_id=6614957

The good news is that the SSL tunneling bug is fixed so you can just use the default factory. I just tried with a proxy and everything works as expected. See my code,

public class SSLContextTest {

    public static void main(String[] args) {

        System.setProperty("https.proxyHost", "proxy.xxx.com");
        System.setProperty("https.proxyPort", "8888");

        try {

            SSLContext sslContext = SSLContext.getInstance("SSL");

            // set up a TrustManager that trusts everything
            sslContext.init(null, new TrustManager[] { new X509TrustManager() {
                public X509Certificate[] getAcceptedIssuers() {
                    System.out.println("getAcceptedIssuers =============");
                    return null;
                }

                public void checkClientTrusted(X509Certificate[] certs,
                        String authType) {
                    System.out.println("checkClientTrusted =============");
                }

                public void checkServerTrusted(X509Certificate[] certs,
                        String authType) {
                    System.out.println("checkServerTrusted =============");
                }
            } }, new SecureRandom());

            HttpsURLConnection.setDefaultSSLSocketFactory(
                    sslContext.getSocketFactory());

            HttpsURLConnection
                    .setDefaultHostnameVerifier(new HostnameVerifier() {
                        public boolean verify(String arg0, SSLSession arg1) {
                            System.out.println("hostnameVerifier =============");
                            return true;
                        }
                    });

            URL url = new URL("https://www.verisign.net");
            URLConnection conn = url.openConnection();
            BufferedReader reader = 
                new BufferedReader(new InputStreamReader(conn.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }
        } catch (Exception e) {
            e.printStackTrace();
        } 
    }
}

This is what I get when I run the program,

checkServerTrusted =============
hostnameVerifier =============
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
......

As you can see, both SSLContext and hostnameVerifier are getting called. HostnameVerifier is only involved when the hostname doesn't match the cert. I used "www.verisign.net" to trigger this.

Use:

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

The option you should use is iDisplayLength:

$('#adminProducts').dataTable({
  'iDisplayLength': 100
});

$('#table').DataTable({
   "lengthMenu": [ [5, 10, 25, 50, -1], [5, 10, 25, 50, "All"] ]
});

It will Load by default all entries.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

If you want to load by default 25 not all do this.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
});

I tried the above solutions. None worked.

In the end I opened Makefile file and manually changed prefix path to desired installation path like below.

PREFIX ?= "installation path"

When I tried --prefix, "make" complained that there is not such command input. However, perhaps some packages accepts --prefix which is of course a cleaner solution.

All OS comes with a default version of python and it resides in /usr/bin. All scripts that come with the OS (e.g. yum) point this version of python residing in /usr/bin. When you want to install a new version of python you do not want to break the existing scripts which may not work with new version of python.

The right way of doing this is to install the python as an alternate version.

e.g.
wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2 
tar xf Python-2.7.3.tar.bz2
cd Python-2.7.3
./configure --prefix=/usr/local/
make && make altinstall

Now by doing this the existing scripts like yum still work with /usr/bin/python. and your default python version would be the one installed in /usr/local/bin. i.e. when you type python you would get 2.7.3

This happens because. $PATH variable has /usr/local/bin before usr/bin.

/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

If python2.7 still does not take effect as the default python version you would need to do

export PATH="/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin"

Not sure how you were calling concat() but it should work as long as both objects are of the same type. Maybe the issue is that you need to cast your second vector to a dataframe? Using the df that you defined the following works for me:

df2 = pd.DataFrame([[2,3,4]], columns=['A','B','C'])
pd.concat([df2, df])

You have to stop the current process and run your new one. In Eclipse, you can press this button to ReLaunch your application:

According to this post this error message means:

Heap size is larger than your computer's physical memory.

Edit: Heap is not the only memory that is reserved, I suppose. At least there are other JVM settings like PermGenSpace that ask for the memory. With heap size 128M and a PermGenSpace of 64M you already fill the space available.

Why not downsize other memory settings to free up space for the heap?

You want:

grep -A 5 '19:55' file

From man grep:

Context Line Control

-A NUM, --after-context=NUM

Print NUM lines of trailing context after matching lines.  
Places a line containing a gup separator (described under --group-separator) 
between contiguous groups of matches.  With the -o or --only-matching
option, this has no effect and a warning is given.

-B NUM, --before-context=NUM

Print NUM lines of leading context before matching lines.  
Places a line containing a group separator (described under --group-separator) 
between contiguous groups of matches.  With the -o or --only-matching
option, this has no effect and a warning is given.

-C NUM, -NUM, --context=NUM

Print NUM lines of output context.  Places a line containing a group separator
(described under --group-separator) between contiguous groups of matches.  
With the -o or --only-matching option,  this  has  no effect and a warning
is given.

--group-separator=SEP

Use SEP as a group separator. By default SEP is double hyphen (--).

--no-group-separator

Use empty string as a group separator.

As of Visual Studio Code version 1.12.0, April 2017, see Basic Editing > Folding section in the docs.

The default keys are:

Fold All: CTRL+K, CTRL+0 (zero)

Fold Level [n]: CTRL+K, CTRL+[n]*

Unfold All: CTRL+K, CTRL+J

Fold Region: CTRL+K, CTRL+[

Unfold Region: CTRL+K, CTRL+]

*Fold Level: to fold all but the most outer classes, try CTRL+K, CTRL+1

Macs: use ? instead of CTRL (thanks Prajeet)

It means something like this:

std::vector<Movie *> movies;

Then you add to the vector as you read lines:

movies.push_back(new Movie(...));

Remember to delete all of the Movie* objects once you are done with the vector.

Another way which could make sense for the given situation is

BigDecimal newBD = oldBD.setScale(2);

I just say this because in some cases when it comes to money going beyond 2 decimal places does not make sense. Taking this a step further, this could lead to

String displayString = oldBD.setScale(2).toPlainString();

but I merely wanted to highlight the setScale method (which can also take a second rounding mode argument to control how that last decimal place is handled. In some situations, Java forces you to specify this rounding method).

You can concatenate strings using strcat. If you plan on concatenating numbers as strings, you must first use num2str to convert the numbers to strings.

Also, strings can't be stored in a vector or matrix, so f must be defined as a cell array, and must be indexed using { and } (instead of normal round brackets).

f = cell(N, 1);
for i=1:N
   f{i} = strcat('f', num2str(i));
end

Alan is correct when he says there's designer support. Rhywun is incorrect when he implies you cannot choose the foreign key table. What he means is that in the UI the foreign key table drop down is greyed out - all that means is he has not right clicked on the correct table to add the foreign key to.

In summary, right click on the foriegn key table and then via the 'Table Properties' > 'Add Relations' option you select the related primary key table.

I've done it numerous times and it works.

You can use this code for remove subtring and also replace , and also remove extra white space . code :

#include<bits/stdc++.h>
using namespace std ;
void removeSpaces(string &str)
{
   
    int n = str.length();

    int i = 0, j = -1;

    bool spaceFound = false;

    while (++j <= n && str[j] == ' ');

    while (j <= n)
    {
        if (str[j] != ' ')
        {
          
            if ((str[j] == '.' || str[j] == ',' ||
                 str[j] == '?') && i - 1 >= 0 &&
                 str[i - 1] == ' ')
                str[i - 1] = str[j++];

            else
                
                str[i++] = str[j++];

            
            spaceFound = false;
        }
        else if (str[j++] == ' ')
        {
            
            if (!spaceFound)
            {
                str[i++] = ' ';
                spaceFound = true;
            }
        }
    }

    if (i <= 1)
        str.erase(str.begin() + i, str.end());
    else
        str.erase(str.begin() + i - 1, str.end());
}
int main()
{
    string s;
    cin>>s;
    for(int i=s.find("WUB");i>=0;i=s.find("WUB"))
    {
        s.replace(i,3," ");
    }
    removeSpaces(s);
    cout<<s<<endl;

    return 0;
}

If you're interested in mapping not only values but also keys, I have written Object.map(valueMapper, keyMapper), that behaves this way:

var source = { a: 1, b: 2 };
function sum(x) { return x + x }

source.map(sum);            // returns { a: 2, b: 4 }
source.map(undefined, sum); // returns { aa: 1, bb: 2 }
source.map(sum, sum);       // returns { aa: 2, bb: 4 }

Older topic but one still relevant. Another issue occurs when an index has become fragmented to the extent of becoming more of a problem than a help. In such a case, the answer would be to rebuild or drop and recreate the index and issuing the delete statement again.

You can use setTimeout():

var addBg = function(e) {_x000D_
  e = e || window.event;_x000D_
  e.preventDefault();_x000D_
  var el = e.target || e.srcElement;_x000D_
  el.className = 'bg';_x000D_
  setTimeout(function() {_x000D_
    removeBg(el);_x000D_
  }, 10 * 1000); //<-- (in miliseconds)_x000D_
};_x000D_
_x000D_
var removeBg = function(el) {_x000D_
  el.className = '';_x000D_
};

div {_x000D_
  border: 1px solid grey;_x000D_
  padding: 5px 7px;_x000D_
  display: inline-block;_x000D_
  margin: 5px;_x000D_
}_x000D_
.bg {_x000D_
  background: orange;_x000D_
}

<body onclick='addBg(event);'>This is body_x000D_
  <br/>_x000D_
  <div onclick='addBg(event);'>This is div_x000D_
  </div>_x000D_
</body>

Using jQuery:

var addBg = function(e) {_x000D_
  e.stopPropagation();_x000D_
  var el = $(this);_x000D_
  el.addClass('bg');_x000D_
  setTimeout(function() {_x000D_
    removeBg(el);_x000D_
  }, 10 * 1000); //<-- (in miliseconds)_x000D_
};_x000D_
_x000D_
var removeBg = function(el) {_x000D_
  $(el).removeClass('bg');_x000D_
};_x000D_
_x000D_
$(function() {_x000D_
  $('body, div').on('click', addBg);_x000D_
});

div {_x000D_
  border: 1px solid grey;_x000D_
  padding: 5px 7px;_x000D_
  display: inline-block;_x000D_
  margin: 5px;_x000D_
}_x000D_
.bg {_x000D_
  background: orange;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>_x000D_
_x000D_
<body>This is body_x000D_
  <br/>_x000D_
  <div>This is div</div>_x000D_
</body>

You may use jQuery in it like

$('#yesh').click(function(){
     *****HERE GOES THE FUNCTION*****
});

Besides jQuery is easy to use.

You can make changes in colors etc using simple jQUery or Javascript.

My scenario is little different, but the intent is same i would like to know when the parent window hosting my user control is closing/closed as The view(i.e my usercontrol) should invoke the presenters oncloseView to execute some functionality and perform clean up. ( well we are implementing a MVP pattern on a WPF PRISM application).

I just figured that in the Loaded event of the usercontrol, i can hook up my ParentWindowClosing method to the Parent windows Closing event. This way my Usercontrol can be aware when the Parent window is being closed and act accordingly!

c="powershell.exe -ExecutionPolicy Bypass (New-Object -ComObject Wscript.Shell).popup('Hello World.',0,'??',64)"

Another option is to search the XML as a string by converting it to a string and then using LIKE. However as a computed column can't be part of a WHERE clause you need to wrap it in another SELECT like this:

SELECT * FROM
    (SELECT *, CONVERT(varchar(MAX), [COLUMNA]) as [XMLDataString] FROM TABLE) x
WHERE [XMLDataString] like '%Test%'

I find that some of these answers are vague and complicated, I find the best way to figure out these things for sure is to just open up the console and test it yourself.

var x;

x == null            // true
x == undefined       // true
x === null           // false
x === undefined      // true

var y = null;

y == null            // true
y == undefined       // true
y === null           // true
y === undefined      // false

typeof x             // 'undefined'
typeof y             // 'object'

var z = {abc: null};

z.abc == null        // true
z.abc == undefined   // true
z.abc === null       // true
z.abc === undefined  // false

z.xyz == null        // true
z.xyz == undefined   // true
z.xyz === null       // false
z.xyz === undefined  // true

null = 1;            // throws error: invalid left hand assignment
undefined = 1;       // works fine: this can cause some problems

So this is definitely one of the more subtle nuances of JavaScript. As you can see, you can override the value of undefined, making it somewhat unreliable compared to null. Using the == operator, you can reliably use null and undefined interchangeably as far as I can tell. However, because of the advantage that null cannot be redefined, I might would use it when using ==.

For example, variable != null will ALWAYS return false if variable is equal to either null or undefined, whereas variable != undefined will return false if variable is equal to either null or undefined UNLESS undefined is reassigned beforehand.

You can reliably use the === operator to differentiate between undefined and null, if you need to make sure that a value is actually undefined (rather than null).

According to the ECMAScript 5 spec:

• Both Null and Undefined are two of the six built in types.

4.3.9 undefined value

primitive value used when a variable has not been assigned a value

4.3.11 null value

primitive value that represents the intentional absence of any object value

It's just PHP, not HTML.

It parses all HTML fields with [] into an array.

So you can have

<input type="checkbox" name="food[]" value="apple" />
<input type="checkbox" name="food[]" value="pear" />

and when submitted, PHP will make $_POST['food'] an array, and you can access its elements like so:

echo $_POST['food'][0]; // would output first checkbox selected

or to see all values selected:

foreach( $_POST['food'] as $value ) {
    print $value;
}

Anyhow, don't think there is a specific name for it

I would start by turning off TCP offloading. There have been a few things that cause intermittent connectivity issues and this is the one that is usually the culprit.

Note: I have seen this setting cause problems on Win Server 2003 and Win Server 2008

One way to 'minimise' the cmd window is to reduce the size of the console using something like...

echo DO NOT CLOSE THIS WINDOW
MODE CON COLS=30 LINES=2

You can reduce the COLS to about 18 and the LINES to 1 if you wish. The advantage is that it works under WinPE, 32-bit or 64-bit, and does not require any 3rd party utility.

I had a case very similar where I was posting in an each loop and then setting the html markup in some fields from numbers received from the ajax. I then needed to do a sum of the (now-updated) values of these fields and place in a total field.

Thus the problem was that I was trying to do a sum on all of the numbers but no data had arrived back yet from the async ajax calls. I needed to complete this functionality in a few functions to be able to reuse the code. My outer function awaits the data before I then go and do some stuff with the fully updated DOM.

    // 1st
    function Outer() {
        var deferreds = GetAllData();

        $.when.apply($, deferreds).done(function () {
            // now you can do whatever you want with the updated page
        });
    }

    // 2nd
    function GetAllData() {
        var deferreds = [];
        $('.calculatedField').each(function (data) {
            deferreds.push(GetIndividualData($(this)));
        });
        return deferreds;
    }

    // 3rd
    function GetIndividualData(item) {
        var def = new $.Deferred();
        $.post('@Url.Action("GetData")', function (data) {
            item.html(data.valueFromAjax);
            def.resolve(data);
        });
        return def;
    }

Currently, the eyedropper tool is not working in my version of Chrome (as described above), though it worked for me in the past. I hear it is being updated in the latest version of Chrome.

However, I'm able to grab colors easily in Firefox.

1. Open page in Firefox
2. Hamburger Menu -> Web Developer -> Eyedropper
3. Drag eyedropper tool over the image... Click.
   Color is copied to your clipboard, and eyedropper tool goes away.
4. Paste color code

In case you cannot get the eyedropper tool to work in Chrome, this is a good work around.
I also find it easier to access :-)

If you want keep character then use split method with loophole in .split() method.

See this example:

public class SplitExample {


    public static void main(String[] args) {  
        String str = "Javathomettt";  
        System.out.println("method 1");
        System.out.println("Returning words:");  
        String[] arr = str.split("t", 40);  
        for (String w : arr) {  
            System.out.println(w+"t");  
        }  
        System.out.println("Split array length: "+arr.length);  
        System.out.println("method 2");
        System.out.println(str.replaceAll("t", "\n"+"t"));
    }

val() is more like a shortcut for attr('value'). For your usage use text() or html() instead

In the accepted answer the ConcurrentBag is not required. Here's an implementation without it:

var tasks = myCollection.Select(GetData).ToList();
await Task.WhenAll(tasks);
var results = tasks.Select(t => t.Result);

Any of the "// some pre stuff" and "// some post stuff" can go into the GetData implementation (or another method that calls GetData)

Aside from being shorter, there's no use of an "async void" lambda, which is an anti pattern.

Take a look in .git/config and make the changes you need.

Alternatively you could use

git remote rm [name of the url you sets on adding]

and

git remote add [name] [URL]

Or just

git remote set-url [URL]

Before you do anything wrong, double check with

git help remote

Like the other answers have said, instance methods operate on an object and has access to its instance variables, while a class method operates on a class as a whole and has no access to a particular instance's variables (unless you pass the instance in as a parameter).

A good example of an class method is a counter-type method, which returns the total number of instances of a class. Class methods start with a +, while instance ones start with an -. For example:

static int numberOfPeople = 0;

@interface MNPerson : NSObject {
     int age;  //instance variable
}

+ (int)population; //class method. Returns how many people have been made.
- (id)init; //instance. Constructs object, increments numberOfPeople by one.
- (int)age; //instance. returns the person age
@end

@implementation MNPerson
- (id)init{
    if (self = [super init]){
          numberOfPeople++;
          age = 0;
    }    
    return self;
}

+ (int)population{ 
     return numberOfPeople;
}

- (int)age{
     return age;
}

@end

main.m:

MNPerson *micmoo = [[MNPerson alloc] init];
MNPerson *jon = [[MNPerson alloc] init];
NSLog(@"Age: %d",[micmoo age]);
NSLog(@"%Number Of people: %d",[MNPerson population]);

Output: Age: 0 Number Of people: 2

Another example is if you have a method that you want the user to be able to call, sometimes its good to make that a class method. For example, if you have a class called MathFunctions, you can do this:

+ (int)square:(int)num{ 
      return num * num;
}

So then the user would call:

[MathFunctions square:34];

without ever having to instantiate the class!

You can also use class functions for returning autoreleased objects, like NSArray's

+ (NSArray *)arrayWithObject:(id)object

That takes an object, puts it in an array, and returns an autoreleased version of the array that doesn't have to be memory managed, great for temperorary arrays and what not.

I hope you now understand when and/or why you should use class methods!!

If you use Wordpress you can just use the wordpress build in function with the video id provided wp_get_attachment_metadata($videoID):

wp_get_attachment_metadata($videoID);

helped me a lot. thats why i'm posting it, although its just for wordpress users.

in the DBAdaper i.e Data Base helper class declare the table like this

 private static final String USERDETAILS=
    "create table userdetails(usersno integer primary key autoincrement,userid text not null ,username text not null,password text not null,photo BLOB,visibility text not null);";

insert the values like this,

first convert the images as byte[]

ByteArrayOutputStream baos = new ByteArrayOutputStream();  
Bitmap bitmap = ((BitmapDrawable)getResources().getDrawable(R.drawable.common)).getBitmap();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);   
byte[] photo = baos.toByteArray(); 
db.insertUserDetails(value1,value2, value3, photo,value2);

in DEAdaper class

 public long insertUserDetails(String uname,String userid, String pass, byte[] photo,String visibility) 
{
    ContentValues initialValues = new ContentValues();
    initialValues.put("username", uname);
    initialValues.put("userid",userid);
    initialValues.put("password", pass);
    initialValues.put("photo",photo);
    initialValues.put("visibility",visibility);
    return db.insert("userdetails", null, initialValues);
}

retrieve the image as follows

Cursor cur=your query;
while(cur.moveToNext())
{
     byte[] photo=cur.getBlob(index of blob cloumn);
}

convert the byte[] into image

ByteArrayInputStream imageStream = new ByteArrayInputStream(photo);
Bitmap theImage= BitmapFactory.decodeStream(imageStream);

I think this content may solve your problem

Try this:

$("a").removeAttr('href');

EDIT-

From your updated code:

 var location= $('#link1').attr("href");
 $("#link1").removeAttr('href');
 $('ul').addClass('expanded');
 $('ul.expanded').fadeIn(300);
 $("#link1").attr("href", location);

As stated in the previous answers,

git push <remote-name> <local-branch-name>:<remote-branch-name>

is enough for pushing a local branch.

Your colleagues, can pull all remote branches (including new ones) with this command:

git remote update

Then, to make changes on the branch, the usual flow:

git checkout -b <local-branch-name> <remote-name>/<remote-branch-name>

Don't forget that you can not cross domains because of security.

So if this is the case, you should use JSON.

you could use the last-child psuedo class

table tr td:last-child {
    border: none;
}

This will style the last td only. It's not fully supported yet so it may be unsuitable

I had a different issue that brought me to this question, which will probably be more common than the overrelease issue in the accepted answer.

Root cause was our completion block being called twice due to bad if/else fallthrough in the network handler, leading to two calls of dispatch_group_leave for every one call to dispatch_group_enter.

Completion block called multiple times:

dispatch_group_enter(group);
[self badMethodThatCallsMULTIPLECompletions:^(NSString *completion) {

    // this block is called multiple times
    // one `enter` but multiple `leave`

    dispatch_group_leave(group);
}];

Debug via the dispatch_group's count

Upon the EXC_BAD_INSTRUCTION, you should still have access to your dispatch_group in the debugger. DispatchGroup: check how many "entered"

Print out the dispatch_group and you'll see:

<OS_dispatch_group: group[0x60800008bf40] = { xrefcnt = 0x2, refcnt = 0x1, port = 0x0, count = -1, waiters = 0 }>

When you see count = -1 it indicates that you've over-left the dispatch_group. Be sure to dispatch_enter and dispatch_leave the group in matched pairs.

This is tailored to finding formulas but you should be able to expand it to general content by altering how you test the starting cells. You'll have to handle single cell ranges outside of this.

    public static Range GetUsedPartOfRange(this Range range)
    {
        Excel.Range beginCell = range.Cells[1, 1];
        Excel.Range endCell = range.Cells[range.Rows.Count, range.Columns.Count];

        if (!beginCell.HasFormula)
        {
            var beginCellRow = range.Find(
                "*",
                beginCell,
                XlFindLookIn.xlFormulas,
                XlLookAt.xlPart,
                XlSearchOrder.xlByRows,
                XlSearchDirection.xlNext,
                false);

            var beginCellCol = range.Find(
                "*",
                beginCell,
                XlFindLookIn.xlFormulas,
                XlLookAt.xlPart,
                XlSearchOrder.xlByColumns,
                XlSearchDirection.xlNext,
                false);

            if (null == beginCellRow || null == beginCellCol)
                return null;

            beginCell = range.Worksheet.Cells[beginCellRow.Row, beginCellCol.Column];
        }

        if (!endCell.HasFormula)
        {
            var endCellRow = range.Find(
            "*",
            endCell,
            XlFindLookIn.xlFormulas,
            XlLookAt.xlPart,
            XlSearchOrder.xlByRows,         
            XlSearchDirection.xlPrevious,
            false);

            var endCellCol = range.Find(
                "*",
                endCell,
                XlFindLookIn.xlFormulas,
                XlLookAt.xlPart,
                XlSearchOrder.xlByColumns,
                XlSearchDirection.xlPrevious,
                false);

            if (null == endCellRow || null == endCellCol)
                return null;

            endCell = range.Worksheet.Cells[endCellRow.Row, endCellCol.Column];
        }

        if (null == endCell || null == beginCell)
            return null;

        Excel.Range finalRng = range.Worksheet.Range[beginCell, endCell];

        return finalRng;
    }
}

another way which can return the list of matching strings is

sample = "alexis has the control"
matched_strings = filter(sample.endswith, ["trol", "ol", "troll"])
print matched_strings
['trol', 'ol']

Put variables that will be changed by your interaction at extraData

You can be creative.

For example if you are dealing with a changing list with checkboxes on them.

<FlatList
      data={this.state.data.items}
      extraData={this.state.data.items.length * (this.state.data.done.length + 1) }
      renderItem={({item}) => <View>  

You could use id in span directly in your html.

<span id="span_id">Client</span>

Then your jQuery code would be

$("#span_id").text();

Some one helped me to check errors and found that he used val() instead of text(), it is not possible to use val() function in span. So

$("#span_id").val();

will return null.

The com.recoyxgroup.javascript.enum package allows you to properly define enum and flags enum classes, where:

• Every constant is represented as an immutable { _value: someNumber }
• Every constant has a property attached to the enum class (E.CONSTANT_NAME)
• Every constant has a friendly String (constantName)
• Every constant has a Number (someNumber)
• You can declare custom properties/methods using E.prototype.

Wherever a specific enum is expected, the convention is to do E(v), like this:

const { FlagsEnum } from 'com.recoyxgroup.javascript.enum';

const Rights = FlagsEnum('Rights', [
    'ADMINISTRATION',
    'REVIEW',
]);

function fn(rights) {
    rights = Rights(rights);
    console.log('administration' in rights, 'review' in rights);
}

fn( ['administration', 'review'] ); // true true
fn( 'administration' ); // true false
fn( undefined ); // false false

var r = Rights.ADMINISTRATION;
console.log( r == 'administration' );

As you can see, you can still compare the value to a String.

Definitions can be more specific:

const E = FlagsEnum('E', [
    ['Q', 0x10],
    ['K', 'someB'],
    ['L', [0x40, 'someL']],
]);

FlagsEnum products > Instance properties/methods

• number (was going to be valueOf(), but because of JS ==, had to be 'number')
• set()
• exclude()
• toggle()
• filter()
• valueOf()
• toString()

Yes, it will serialize and deserialize a List<>. Just make sure you use the [XmlArray] attribute if in doubt.

[Serializable]
public class A
{
    [XmlArray]
    public List<string> strings;
}

This works with both Serialize() and Deserialize().

The error message explains it pretty well:

ValueError: The truth value of an array with more than one element is ambiguous. 
Use a.any() or a.all()

What should bool(np.array([False, False, True])) return? You can make several plausible arguments:

(1) True, because bool(np.array(x)) should return the same as bool(list(x)), and non-empty lists are truelike;

(2) True, because at least one element is True;

(3) False, because not all elements are True;

and that's not even considering the complexity of the N-d case.

So, since "the truth value of an array with more than one element is ambiguous", you should use .any() or .all(), for example:

>>> v = np.array([1,2,3]) == np.array([1,2,4])
>>> v
array([ True,  True, False], dtype=bool)
>>> v.any()
True
>>> v.all()
False

and you might want to consider np.allclose if you're comparing arrays of floats:

>>> np.allclose(np.array([1,2,3+1e-8]), np.array([1,2,3]))
True

A bit off on the "duck typing" definition -- dict.keys() returns an iterable object, not a list-like object. It will work anywhere an iterable will work -- not any place a list will. a list is also an iterable, but an iterable is NOT a list (or sequence...)

In real use-cases, the most common thing to do with the keys in a dict is to iterate through them, so this makes sense. And if you do need them as a list you can call list().

Very similarly for zip() -- in the vast majority of cases, it is iterated through -- why create an entire new list of tuples just to iterate through it and then throw it away again?

This is part of a large trend in python to use more iterators (and generators), rather than copies of lists all over the place.

dict.keys() should work with comprehensions, though -- check carefully for typos or something... it works fine for me:

>>> d = dict(zip(['Sounder V Depth, F', 'Vessel Latitude, Degrees-Minutes'], [None, None]))
>>> [key.split(", ") for key in d.keys()]
[['Sounder V Depth', 'F'], ['Vessel Latitude', 'Degrees-Minutes']]

You should use System.Windows.Controls.UserControl's FindResource() or TryFindResource() methods.

Also, a good practice is to create a string constant which maps the name of your key in the resource dictionary (so that you can change it at only one place).

As usual apache-commons has proper method MapUtils.putAll(Map, Object[]):

For example, to create a color map:

Map<String, String> colorMap = MapUtils.putAll(new HashMap<String, String>(), new String[][] {
     {"RED", "#FF0000"},
     {"GREEN", "#00FF00"},
     {"BLUE", "#0000FF"}
 });

Figured it out. Used this instead.

$('.div_class').load('http://en.wikipedia.org/wiki/Cross-origin_resource_sharing #toctitle');

While using the date formats, you may want to keep in mind to always use MM for months and mm for minutes. That should resolve your problem.

To send CDATA in a request object use the SoapObject.setInnerText("..."); method.

$sql = "select count(column_name) as count from table";

With CSS Shapes you can go one step further than just float text around a rectangular image.

You can actually wrap text such that it takes the shape of the edge of the image or polygon that you are wrapping it around.

If you do not care about the names of the 3rd or 4th columns of the second df, you can coerce them to be the same:

> names(xd.small[[1]]) <- names(xd.small[[2]]) 
> identical(names(xd.small[[1]]), names(xd.small[[2]]) )
[1] TRUE

Then things should proceed happily.

I had trouble passing parameters to the Commands.AddScript method.

C:\Foo1.PS1 Hello World Hunger
C:\Foo2.PS1 Hello World

scriptFile = "C:\Foo1.PS1"

parameters = "parm1 parm2 parm3" ... variable length of params

I Resolved this by passing null as the name and the param as value into a collection of CommandParameters

Here is my function:

private static void RunPowershellScript(string scriptFile, string scriptParameters)
{
    RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();
    Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration);
    runspace.Open();
    RunspaceInvoke scriptInvoker = new RunspaceInvoke(runspace);
    Pipeline pipeline = runspace.CreatePipeline();
    Command scriptCommand = new Command(scriptFile);
    Collection<CommandParameter> commandParameters = new Collection<CommandParameter>();
    foreach (string scriptParameter in scriptParameters.Split(' '))
    {
        CommandParameter commandParm = new CommandParameter(null, scriptParameter);
        commandParameters.Add(commandParm);
        scriptCommand.Parameters.Add(commandParm);
    }
    pipeline.Commands.Add(scriptCommand);
    Collection<PSObject> psObjects;
    psObjects = pipeline.Invoke();
}

Comparing Java 7 and C# 3

(Some features of Java 7 aren't mentioned here, but the using statement advantage of all versions of C# over Java 1-6 has been removed.)

Not all of your summary is correct:

• In Java methods are virtual by default but you can make them final. (In C# they're sealed by default, but you can make them virtual.)
• There are plenty of IDEs for Java, both free (e.g. Eclipse, Netbeans) and commercial (e.g. IntelliJ IDEA)

Beyond that (and what's in your summary already):

• Generics are completely different between the two; Java generics are just a compile-time "trick" (but a useful one at that). In C# and .NET generics are maintained at execution time too, and work for value types as well as reference types, keeping the appropriate efficiency (e.g. a List<byte> as a byte[] backing it, rather than an array of boxed bytes.)
• C# doesn't have checked exceptions
• Java doesn't allow the creation of user-defined value types
• Java doesn't have operator and conversion overloading
• Java doesn't have iterator blocks for simple implemetation of iterators
• Java doesn't have anything like LINQ
• Partly due to not having delegates, Java doesn't have anything quite like anonymous methods and lambda expressions. Anonymous inner classes usually fill these roles, but clunkily.
• Java doesn't have expression trees
• C# doesn't have anonymous inner classes
• C# doesn't have Java's inner classes at all, in fact - all nested classes in C# are like Java's static nested classes
• Java doesn't have static classes (which don't have any instance constructors, and can't be used for variables, parameters etc)
• Java doesn't have any equivalent to the C# 3.0 anonymous types
• Java doesn't have implicitly typed local variables
• Java doesn't have extension methods
• Java doesn't have object and collection initializer expressions
• The access modifiers are somewhat different - in Java there's (currently) no direct equivalent of an assembly, so no idea of "internal" visibility; in C# there's no equivalent to the "default" visibility in Java which takes account of namespace (and inheritance)
• The order of initialization in Java and C# is subtly different (C# executes variable initializers before the chained call to the base type's constructor)
• Java doesn't have properties as part of the language; they're a convention of get/set/is methods
• Java doesn't have the equivalent of "unsafe" code
• Interop is easier in C# (and .NET in general) than Java's JNI
• Java and C# have somewhat different ideas of enums. Java's are much more object-oriented.
• Java has no preprocessor directives (#define, #if etc in C#).
• Java has no equivalent of C#'s ref and out for passing parameters by reference
• Java has no equivalent of partial types
• C# interfaces cannot declare fields
• Java has no unsigned integer types
• Java has no language support for a decimal type. (java.math.BigDecimal provides something like System.Decimal - with differences - but there's no language support)
• Java has no equivalent of nullable value types
• Boxing in Java uses predefined (but "normal") reference types with particular operations on them. Boxing in C# and .NET is a more transparent affair, with a reference type being created for boxing by the CLR for any value type.

This is not exhaustive, but it covers everything I can think of off-hand.

I think the easiest way to match the characters like

\^$.?*|+()[

are using character classes from within R. Consider the following to clean column headers from a data file, which could contain spaces, and punctuation characters:

> library(stringr)
> colnames(order_table) <- str_replace_all(colnames(order_table),"[:punct:]|[:space:]","")

This approach allows us to string character classes to match punctation characters, in addition to whitespace characters, something you would normally have to escape with \\ to detect. You can learn more about the character classes at this cheatsheet below, and you can also type in ?regexp to see more info about this.

https://www.rstudio.com/wp-content/uploads/2016/09/RegExCheatsheet.pdf

There is actually another way of looking at this problem, not as a number problem, but a Unary problem, starting with the base character of Roman numbers, "I". So we represent the number with just I, and then we replace the characters in ascending value of the roman characters.

public String getRomanNumber(int number) {
    return join("", nCopies(number, "I"))
            .replace("IIIII", "V")
            .replace("IIII", "IV")
            .replace("VV", "X")
            .replace("VIV", "IX")
            .replace("XXXXX", "L")
            .replace("XXXX", "XL")
            .replace("LL", "C")
            .replace("LXL", "XC")
            .replace("CCCCC", "D")
            .replace("CCCC", "CD")
            .replace("DD", "M")
            .replace("DCD", "CM");
}

I especially like this method of solving this problem rather than using a lot of ifs and while loops, or table lookups. It is also actually a quit intuitive solution when you thinking of the problem not as a number problem.

When searching folders where you might get an error based on security (e.g. C:\Users), use the following command:

Get-ChildItem -Path V:\Myfolder -Filter CopyForbuild.bat -Recurse -ErrorAction SilentlyContinue -Force

This works fine for me:

while True:
   answer = input('Do you want to continue?:')
   if answer.lower().startswith("y"):
      print("ok, carry on then")
   elif answer.lower().startswith("n"):
      print("sayonara, Robocop")
      exit()

edit: use input in python 3.2 instead of raw_input

my issue with ANR , after much work i found out that a thread was calling a resource that did not exist in the layout, instead of returning an exception , i got ANR ...

You should use RegExp (they are awesome) an easy solution is:

if( /^bird/.test(animals[i]) ){
    // a bird :D
}

A quick and easy way is to use jQuery and do this:

var $eles = $(":input[name^='q1_']").css("color","yellow");

That will grab all elements whose name attribute starts with 'q1_'. To convert the resulting collection of jQuery objects to a DOM collection, do this:

var DOMeles = $eles.get();

see http://api.jquery.com/attribute-starts-with-selector/

In pure DOM, you could use getElementsByTagName to grab all input elements, and loop through the resulting array. Elements with name starting with 'q1_' get pushed to another array:

var eles = [];
var inputs = document.getElementsByTagName("input");
for(var i = 0; i < inputs.length; i++) {
    if(inputs[i].name.indexOf('q1_') == 0) {
        eles.push(inputs[i]);
    }
}

For all who've opted for the if-else mesh solution, please use:

String columnName = metadata.getColumnName(
String displayName = metadata.getColumnLabel(i);
switch (metadata.getColumnType(i)) {
case Types.ARRAY:
    obj.put(displayName, resultSet.getArray(columnName));
    break;
...

Because in case of aliases in your query, the column name and column label are two different things. For example if you execute:

select col1, col2 as my_alias from table

You will get

[
    { "col1": 1, "col2": 2 }, 
    { "col1": 1, "col2": 2 }
]

Rather than:

[
    { "col1": 1, "my_alias": 2 }, 
    { "col1": 1, "my_alias": 2 }
]

SELECT tab.*,
    row_number() OVER () as rnum
  FROM tab;

Here's the relevant section in the docs.

P.S. This, in fact, fully matches the answer in the referenced question.

According to the spec for locating Schemas

there may or may not be a schema retrievable via the namespace name... User community and/or consumer/provider agreements may establish circumstances in which [trying to retrieve an xsd from the namespace url] is a sensible default strategy

(thanks for being unambiguous, spec!)

and

in case a document author (human or not) created a document with a particular schema in view, and warrants that some or all of the document conforms to that schema, the schemaLocation and noNamespaceSchemaLocation [attributes] are provided.

So basically with specifying just a namespace, your XML "might" be attempted to be validated against an xsd at that location (even if it lacks a schemaLocation attribute), depending on your "community." If you specify a specific schemaLocation, then it basically is implying that the xml document "should" be conformant to said xsd, so "please validate it" (as I read it). My guess is that if you don't do a schemaLocation or noNamespaceSchemaLocation attribute it just "isn't validated" most of the time (based on the other answers, appears java does it this way).

Another wrinkle here is that typically, with xsd validation in java libraries [ex: spring config xml files], if your XML files specifies a particular schemaLocation xsd url in an XML file, like xsi:schemaLocation="http://somewhere http://somewhere/something.xsd" typically within one of your dependency jars it will contain a copy of that xsd file, in its resources section, and spring has a "mapping" capability saying to treat that xsd file as if it maps to the url http://somewhere/something.xsd (so you never end up going to web and downloading the file, it just exists locally). See also https://stackoverflow.com/a/41225329/32453 for slightly more info.

Here's a way to do it without using groups (Python 3.6 or above):

>>> re.search('2\d\d\d[01]\d[0-3]\d', 'report_20191207.xml')[0]
'20191207'

 If Short.TryParse(editTransactionRow.pay_id, New Short) Then editTransactionRow.pay_id.ToString()

Didn't wan to mess with carbon. So here's my solution

$start = new \DateTime('now');
$start->modify('first day of this month');
$end = new \DateTime('now');
$end->modify('last day of this month');

$new_releases = Game::whereBetween('release', array($start, $end))->get();

Here are some examples:

> z$mean <- rowMeans(subset(z, select = c(x, y)), na.rm = TRUE)
> z
  w x  y mean
1 5 1  1    1
2 6 2  2    2
3 7 3  3    3
4 8 4 NA    4

weighted mean

> z$y <- rev(z$y)
> z
  w x  y mean
1 5 1 NA    1
2 6 2  3    2
3 7 3  2    3
4 8 4  1    4
> 
> weight <- c(1, 2) # x * 1/3 + y * 2/3
> z$wmean <- apply(subset(z, select = c(x, y)), 1, function(d) weighted.mean(d, weight, na.rm = TRUE))
> z
  w x  y mean    wmean
1 5 1 NA    1 1.000000
2 6 2  3    2 2.666667
3 7 3  2    3 2.333333
4 8 4  1    4 2.000000

It is possibly because the value of val is actually the string "null" rather than the value null.

use

print(reversed(list_name))

Can't change the default browser, but try this (found online a while ago). Add a bookmark in Safari called "Open in Chrome" with the following.

javascript:location.href=%22googlechrome%22+location.href.substring(4);

Will open the current page in Chrome. Not as convenient, but maybe someone will find it useful.

Works for me.

The above answers require you to malloc a new stream object.

public <T>
boolean containsByLambda(Collection<? extends T> c, Predicate<? super T> p) {

    for (final T z : c) {
        if (p.test(z)) {
            return true;
        }
    }
    return false;
}

public boolean containsTabById(TabPane tabPane, String id) {
    return containsByLambda(tabPane.getTabs(), z -> z.getId().equals(id));
}
...
if (containsTabById(tabPane, idToCheck))) {
   ...
}

Now the plugin is Multi Line tricks. The end and start buttons broke the selection.

Your web pages are served by an application pool. If you disable/stop the application pool, and anyone tries to browse the application, you will get a Service Unavailable. It can happen due to multiple reasons...

1. Your application may have crashed [check the event viewer and see if you can find event logs in your Application/System log]

2. Your application may be crashing very frequently. If an app pool crashes for 5 times in 5 minutes [check your application pool settings for rapid fail], your application pool is disabled by IIS and you will end up getting this message.

In either case, the issue is that your worker process is failing and you should troubleshoot it from crash perspective.

What is a Crash (technically)... in ASP.NET and what to do if it happens?

I will group the options based on output. Assume the following vector for all the examples.

v <- c('z', 'a','b','a','e')

For checking presence:

%in%

> 'a' %in% v
[1] TRUE

any()

> any('a'==v)
[1] TRUE

is.element()

> is.element('a', v)
[1] TRUE

For finding first occurance:

match()

> match('a', v)
[1] 2

For finding all occurances as vector of indices:

which()

> which('a' == v)
[1] 2 4

For finding all occurances as logical vector:

==

> 'a' == v
[1] FALSE  TRUE FALSE  TRUE FALSE

Edit: Removing grep() and grepl() from the list for reason mentioned in comments

For fixing such an issue I have used below code

a.divide(b, 2, RoundingMode.HALF_EVEN)

2 is precision. Now problem was resolved.

You need to set the g flag to replace globally:

date.replace(new RegExp("/", "g"), '')
// or
date.replace(/\//g, '')

Otherwise only the first occurrence will be replaced.

I also faced the same issue...try to do this...this worked for me

        .scrollBbar 
        {
        position:fixed;
        top:50px;
        bottom:0;
        left:0;
        width:200px;
        overflow-x:hidden;
        overflow-y:auto;
       }

There's also php2xmi. You have to do a bit of manual work, but it generates all the classes, so all you have to do is to drag them into a classdiagram in Umbrello.

Otherwise, generating a diagram with the use of reflection and graphviz, is fairly simple. I have a snippet over here, that you can use as a starting point.

ksh93:

dt=${ printf "%(%a %d/%m/%Y)T" yesterday; }

or:

dt=$(printf "%(%a %d/%m/%Y)T" yesterday)

The first one runs in the same process, the second one in a subshell.

After you correct the possible dmp file problem, this is a way to ensure that the schema is remapped and imported appropriately. This will also ensure that the tablespace will change also, if needed:

impdp system/<password> SCHEMAS=user1 remap_schema=user1:user2 \
            remap_tablespace=user1:user2 directory=EXPORTDIR \
            dumpfile=user1.dmp logfile=E:\Data\user1.log

EXPORTDIR must be defined in oracle as a directory as the system user

create or replace directory EXPORTDIR as 'E:\Data';
grant read, write on directory EXPORTDIR to user2;

Also, It can be done with LINQ

var str = "Hello@Hello&Hello(Hello)";
var characters = str.Select(c => char.IsLetter(c) ? c : ',')).ToArray();             
var output = new string(characters);
Console.WriteLine(output);

That is taking the parameter by reference. So in the first case you are taking a pointer parameter by reference so whatever modification you do to the value of the pointer is reflected outside the function. Second is the simlilar to first one with the only difference being that it is a double pointer. See this example:

void pass_by_value(int* p)
{
    //Allocate memory for int and store the address in p
    p = new int;
}

void pass_by_reference(int*& p)
{
    p = new int;
}

int main()
{
    int* p1 = NULL;
    int* p2 = NULL;

    pass_by_value(p1); //p1 will still be NULL after this call
    pass_by_reference(p2); //p2 's value is changed to point to the newly allocate memory

    return 0;
}

You just need to write the first query as a subquery (derived table), inside parentheses, pick an alias for it (t below) and alias the columns as well.

The DISTINCT can also be safely removed as the internal GROUP BY makes it redundant:

SELECT DATE(`date`) AS `date` , COUNT(`player_name`) AS `player_count`
FROM (
    SELECT MIN(`date`) AS `date`, `player_name`
    FROM `player_playtime`
    GROUP BY `player_name`
) AS t
GROUP BY DATE( `date`) DESC LIMIT 60 ;

Since the COUNT is now obvious that is only counting rows of the derived table, you can replace it with COUNT(*) and further simplify the query:

SELECT t.date , COUNT(*) AS player_count
FROM (
    SELECT DATE(MIN(`date`)) AS date
    FROM player_playtime
    GROUP BY player_name
) AS t
GROUP BY t.date DESC LIMIT 60 ;

I found this question by searching Google for "mysql workbench export database sql file". The answers here did not help me, but I eventually did find the answer, so I am posting it here for future generations to find:

Answer

In MySQLWorkbench 6.0, do the following:

1. Select the appropriate database under MySQL Connections
2. On the top-left hand side of screen, under the MANAGEMENT heading, select "Data Export".

Here is a screenshot for reference:

Consider that you have multiple "tests", e.g.,

1. If E2 = 'in play' and F2 = 'closed', output 3
2. If E2 = 'in play' and F2 = 'suspended', output 2
3. Etc.

What you really need to do is put successive tests in the False argument. You're presently trying to separate each test by a comma, and that won't work.

Your first three tests can all be joined in one expression like:

=IF(E2="In Play",IF(F2="Closed",3,IF(F2="suspended",2,IF(F2="Null",1))))

Remembering that each successive test needs to be the nested FALSE argument of the preceding test, you can do this:

=IF(E2="In Play",IF(F2="Closed",3,IF(F2="suspended",2,IF(F2="Null",1))),IF(AND(E2="Pre-Play",F2="Null"),-1,IF(AND(E2="completed",F2="closed"),2,IF(AND(E2="suspended",F2="Null"),3,-2))))

Use the following steps for setup

1. Download from Flutter SDK for Mac https://flutter.dev/docs/get-started/install/macos

2. Extract the Flutter SDK zip (saved in Downloads) file using terminal. If you want to extract the Flutter SDK in fluttrerDevelopment folder

   $ cd ~/fluttrerDevelopment

   $ unzip ~/Downloads/flutter_macos_1.20.1-stable.zip

3. Add the flutter tool to your path:

   $ export PATH=“$PATH:pwd/flutter/bin"

4. If you have only Xcode setup in your machine then run

   $ flutter create my_first_flutter_app

   $ cd my_first_flutter_app

   $ flutter run

To access a class method inside a instance method, do the following:

self.class.default_make

Here is an alternative solution for your problem:

class Truck

  attr_accessor :make, :year

  def self.default_make
    "Toyota"
  end

  def make
    @make || self.class.default_make
  end

  def initialize(make=nil, year=nil)
    self.year, self.make = year, make
  end
end

Now let's use our class:

t = Truck.new("Honda", 2000)
t.make
# => "Honda"
t.year
# => "2000"

t = Truck.new
t.make
# => "Toyota"
t.year
# => nil

In your Gem file, write

gem 'execjs'
gem 'therubyracer'

and then run

bundle install

Everything works fine for me :)

You could also select webpack build manually from the UI

It is probably not a correct way for clean, but I made that to delete unnecessary files, and take less size of a project. It continuously finds and deletes all build and Gradle folders made file clean.bat copy that into the folder where your project is

  set mypath=%cd% 
    for /d /r %mypath% %%a in (build\) do if exist "%%a" rmdir /s /q "%%a"
    for /d /r %mypath% %%a in (.gradle\) do if exist "%%a" rmdir /s /q "%%a"

Following example uses InputBox method to validate user entry to unhide sheets: Important thing here is to use wrap InputBox variable inside StrPtr so it could be compared to '0' when user chose to click 'x' icon on the InputBox.

Sub unhidesheet()

Dim ws As Worksheet
Dim pw As String

pw = InputBox("Enter Password to Unhide Sheets:", "Unhide Data Sheets")
If StrPtr(pw) = 0 Then

   Exit Sub
ElseIf pw = NullString Then
   Exit Sub
ElseIf pw = 123456 Then
    For Each ws In ThisWorkbook.Worksheets
        ws.Visible = xlSheetVisible
    Next
End If
End Sub

from __future__ import with_statement

try:
    with open( "a.txt" ) as f :
        print f.readlines()
except EnvironmentError: # parent of IOError, OSError *and* WindowsError where available
    print 'oops'

If you want different handling for errors from the open call vs the working code you could do:

try:
    f = open('foo.txt')
except IOError:
    print('error')
else:
    with f:
        print f.readlines()

If make config works for your program or you have a shell script which copies your two files to the appropriate place you can use checkinstall. Just go to the directory where your makefile is in and call it with the parameter -R (for RPM) and optionally with the installation script.

shell request failed on channel 0

mean you don't have shell or remote commands access, fix your user permission on server to have shell access or if you just want tunneling use -N and -T options

You should remove .Value from all option buttons because option buttons don't hold the resultant value, the option group control does. If you omit .Value then the default interface will report the option button status, as you are expecting. You should write all relevant code under commandbutton_click events because whenever the commandbutton is clicked the option button action will run.

If you want to run action code when the optionbutton is clicked then don't write an if loop for that.

EXAMPLE:

Sub CommandButton1_Click
    If OptionButton1 = true then
        (action code...)
    End if
End sub

Sub OptionButton1_Click   
    (action code...)
End sub

In SQL Server 2008, you could use the new DATE datatype

DECLARE @pDate DATE='2008-08-14'  

SELECT colA, colB
FROM table1
WHERE convert(date, colDateTime) = @pDate  

@Guy. I think you will find that this solution scales just fine. Have a look at the query execution plan of your original query.

And for mine:

It's no join since the relationship will only be evaluated when needed. A join (in a SQL database) on the other hand will resolve relationships and return them as if they were a single table (you "join two tables into one").

You can read more about DBRef here: http://docs.mongodb.org/manual/applications/database-references/

There are two possible solutions for resolving references. One is to do it manually, as you have almost described. Just save a document's _id in another document's other_id, then write your own function to resolve the relationship. The other solution is to use DBRefs as described on the manual page above, which will make MongoDB resolve the relationship client-side on demand. Which solution you choose does not matter so much because both methods will resolve the relationship client-side (note that a SQL database resolves joins on the server-side).

A one-liner with commons-io:

List<String> lines = FileUtils.readLines(new File("/path/to/file.txt"), "utf-8");

The same with guava:

List<String> lines = 
     Files.readLines(new File("/path/to/file.txt"), Charset.forName("utf-8"));

1. Give 1 day expiry time for the tokens
2. Maintain a daily blacklist.
3. Put the invalidated / logout tokens into the blacklist

For token validation, check for the token expiry time first and then the blacklist if token not expired.

For long session needs, there should be a mechanism for extending token expiry time.

You can also use array_keys() . Newbie friendly:

$keys = array_keys($arrayToWalk);
$arraySize = count($arrayToWalk); 

for($i=0; $i < $arraySize; $i++) {
    echo '<option value="' . $keys[$i] . '">' . $arrayToWalk[$keys[$i]] . '</option>';
}

go to services and start the ones related to SQL

Obviously this is a late answer, but I have a better option if you can use .NET 4.5 or newer:

internal static void WriteInformation<T>(string text, [CallerMemberName]string method = "")
{
    Console.WriteLine(DateTime.Now.ToString() + " => " + typeof(T).FullName + "." + method + ": " + text);
}

This will print the current Date and Time, followed by "Namespace.ClassName.MethodName" and ending with ": text".
Sample output:

6/17/2016 12:41:49 PM => WpfApplication.MainWindow..ctor: MainWindow initialized

Sample use:

Logger.WriteInformation<MainWindow>("MainWindow initialized");

I am wondering if you are after something like Squiggle. Also something very useful is jDBI. It won't help you with the queries though.

sometimes, when you create package like com.mydomain.something the directory structure does not get created and you are left with a single folder named "com.mydomain.something" in this case you should create directory structure, like

com
|_mydomain
  |_something 

When you mark your method as @Transactional, occurrence of any exception inside your method will mark the surrounding TX as roll-back only (even if you catch them). You can use other attributes of @Transactional annotation to prevent it of rolling back like:

@Transactional(rollbackFor=MyException.class, noRollbackFor=MyException2.class)

 X <- data.frame(Variable1=c(11,14,12,15),Variable2=c(2,3,1,4))
> X
  Variable1 Variable2
1        11         2

You can functionalize this however you like.

Within the class you can call function by using :

 $this->filter();

Outside of the class

you have to create an object of a class

 ex: $obj = new Functions();

     $obj->filter($param);    

for more about OOPs in php

this example:

class test {
 public function newTest(){
      $this->bigTest();// we don't need to create an object we can call simply using $this
      $this->smallTest();
 }

 private function bigTest(){
      //Big Test Here
 }

 private function smallTest(){
      //Small Test Here
 }

 public function scoreTest(){
      //Scoring code here;
 }
}

$testObject = new test();

$testObject->newTest();

$testObject->scoreTest();

hope it will help!

I had the same problem using rvm on Ubuntu, was fixed by setting the source on my terminal as a short-term solution:

source $HOME/.rvm/scripts/rvm

or

source /home/$USER/.rvm/scripts/rvm

and configure a default Ruby Version, 2.3.3 in my case.

rvm use 2.3.3 --default

And a long-term Solution is to add your source to your .bashrc file to permanently make Ubuntu look in .rvm for all the Ruby files.

Add:

source .rvm/scripts/rvm

into

$HOME/.bashrc file.

Try calling it like: obj.some_function( '1', 2, '3', g="foo", h="bar" ). After the required positional arguments, you can specify specific optional arguments by name.

You may do this as of C# 9.0:

switch(myvar)
{
    case 2 or 5:
        // ...
        break;

    case 7 or 12:
        // ...
        break;
    // ...
}

The following code works:

find /tmp | perl -ne 'print if /[^[:ascii:]]/'

Replace /tmp with the name of the directory you want to search through.

If someone is here in 2020, after making all the pipes, if u pipe %>% na.exclude will take away all the NAs in the pipe!

This problem is commonly related to compiler errors in the Java code. Sometimes Android Studio does not show these errors in the Project explorer. However, when a problematic .java file is opened, errors are shown. Try to resolve errors and rebuild the project.

Maybe it's even better if you determine position using indexOf() like this:

function insertString(a, b, at)
{
    var position = a.indexOf(at); 

    if (position !== -1)
    {
        return a.substr(0, position) + b + a.substr(position);    
    }  

    return "substring not found";
}

then call the function like this:

insertString("I want apple", "an ", "apple");

Note, that I put a space after the "an " in the function call, rather than in the return statement.

You can add position: fixed; with top left right bottom 0 attribute, that solution work on older browsers too.

If you want to embed it, add position: absolute; to the wrapper, and position: relative to the div outside of the wrapper.

Although this doesn't view the database on your device directly, I've published a simple shell script for dumping databases to your local machine:

https://github.com/Pixplicity/dbdump

It performs two distinct methods described here:

1. First, it tries to make the file accessible for other users, and attempting to pull it from the device.
2. If that fails, it streams the contents of the file over the terminal to the local machine. It performs an additional trick to remove \r characters that some devices output to the shell.

From here you can use a variety of CLI or GUI SQLite applications, such as sqlite3 or sqlitebrowser, to browse the contents of the database.

Try this.

Does not require any options to change.

Does not require any command line activity.

Just run software and you will done the job.

Happy Knowledge Sharing

Ok, years later using VS 2017 .NET Core 2.2 Razor Pages I feel this answer might help someone. If it was a snake it would have bit me. I was throwing stuff around, changing names, renaming Models, and all of a sudden I got this error:

Error CS0246 The type or namespace name 'UploadFileModel' could not be found (are you missing a using directive or an assembly reference?)

This was underlined in red in my .chstml Razor Page. (not underlined after fix):

@page
@model UploadFileModel

So, finally, and luckily, I found the code from someone else that I had originally used, and low and behold, the namespace did not include the .cshtml file name!!!

Here is my bad dummy error spank myself with the page name in the namespace:

namespace OESAC.Pages.UploadFile
{
    public class UploadFileModel : PageModel
    {

What my original code had and all I had to do was delete the page name from the namespace, UploadFile:

namespace OESAC.Pages
{
    public class UploadFileModel : PageModel
    {

And low and behold, all the errors disappeared!! Silly me. But you know, MS has made this .NET C# MVC stuff really confusing for us non-computer scientists. I am constantly tripping on my shoelaces trying to figure out model names, page names, and syntax to use them. It shouldn't be this hard. Oh well. I hope error and solution helps someone. The error was right, there is no Namespace named "UploadFileModel" haha.

As noted elsewhere, you can use join.

If you are using commands as inputs (as I was), use the following syntax:

-join($(Command1), "," , $(Command2))

This would result in the two outputs separated by a comma.

There are several ways to intercept the initialization process in Spring. If you have to initialize all beans and autowire/inject them there are at least two ways that I know of that will ensure this. I have only testet the second one but I belive both work the same.

If you are using @Bean you can reference by initMethod, like this.

@Configuration
public class BeanConfiguration {

  @Bean(initMethod="init")
  public BeanA beanA() {
    return new BeanA();
  }
}

public class BeanA {

  // method to be initialized after context is ready
  public void init() {
  }

} 

If you are using @Component you can annotate with @EventListener like this.

@Component
public class BeanB {

  @EventListener
  public void onApplicationEvent(ContextRefreshedEvent event) {
  }
}

In my case I have a legacy system where I am now taking use of IoC/DI where Spring Boot is the choosen framework. The old system brings many circular dependencies to the table and I therefore must use setter-dependency a lot. That gave me some headaches since I could not trust @PostConstruct since autowiring/injection by setter was not yet done. The order is constructor, @PostConstruct then autowired setters. I solved it with @EventListener annotation which wil run last and at the "same" time for all beans. The example shows implementation of InitializingBean aswell.

I have two classes (@Component) with dependency to each other. The classes looks the same for the purpose of this example displaying only one of them.

@Component
public class BeanA implements InitializingBean {
  private BeanB beanB;

  public BeanA() {
    log.debug("Created...");
  }

  @PostConstruct
  private void postConstruct() {
    log.debug("@PostConstruct");
  }

  @Autowired
  public void setBeanB(BeanB beanB) {
    log.debug("@Autowired beanB");
    this.beanB = beanB;
  }

  @Override
  public void afterPropertiesSet() throws Exception {
    log.debug("afterPropertiesSet()");
  }

  @EventListener
  public void onApplicationEvent(ContextRefreshedEvent event) {
    log.debug("@EventListener");
  } 
}

This is the log output showing the order of the calls when the container starts.

As you can see @EventListener is run last after everything is ready and configured.

The port numbers are defined in RFC 6120 § 14.7.

It's simple. Do a

git fetch --all

I have done with this.

sudo apt-get update
sudo apt-get install build-essential chrpath git-core libssl-dev libfontconfig1-dev
git clone git://github.com/ariya/phantomjs.git
cd phantomjs
git checkout 1.9
./build.sh

Try this

INSERT INTO TABLE2 (Cols...) SELECT Cols... FROM TABLE1 WHERE Criteria

Then

DELETE FROM TABLE1 WHERE Criteria

Very easy solution using Console of the browser. You copy this into your browser console and hit enter:

$("div.input div.prompt_container").on('click', function(e){
    $($(e.target).closest('div.input').find('div.input_area')[0]).toggle();
});

Then you toggle the code of the cell simply by clicking on the number of cell input.

A little bit of decorator treatment (very loosely inspired by the Maybe monad and lifting). You can safely remove Python 3.6 type annotations and use an older message formatting style.

fallible.py

from functools import wraps
from typing import Callable, TypeVar, Optional
import logging


A = TypeVar('A')


def fallible(*exceptions, logger=None) \
        -> Callable[[Callable[..., A]], Callable[..., Optional[A]]]:
    """
    :param exceptions: a list of exceptions to catch
    :param logger: pass a custom logger; None means the default logger, 
                   False disables logging altogether.
    """
    def fwrap(f: Callable[..., A]) -> Callable[..., Optional[A]]:

        @wraps(f)
        def wrapped(*args, **kwargs):
            try:
                return f(*args, **kwargs)
            except exceptions:
                message = f'called {f} with *args={args} and **kwargs={kwargs}'
                if logger:
                    logger.exception(message)
                if logger is None:
                    logging.exception(message)
                return None

        return wrapped

    return fwrap

Demo:

In [1] from fallible import fallible

In [2]: @fallible(ArithmeticError)
    ...: def div(a, b):
    ...:     return a / b
    ...: 
    ...: 

In [3]: div(1, 2)
Out[3]: 0.5

In [4]: res = div(1, 0)
ERROR:root:called <function div at 0x10d3c6ae8> with *args=(1, 0) and **kwargs={}
Traceback (most recent call last):
  File "/Users/user/fallible.py", line 17, in wrapped
    return f(*args, **kwargs)
  File "<ipython-input-17-e056bd886b5c>", line 3, in div
    return a / b

In [5]: repr(res)
'None'

You can also modify this solution to return something a bit more meaningful than None from the except part (or even make the solution generic, by specifying this return value in fallible's arguments).

According to pywin32 github you must run

    pip install pywin32

and after that, you must run

    python Scripts/pywin32_postinstall.py -install

I know I'm reviving an old thread, but I just had this problem and this was the only way to solve it.

With the constructor:

// create a vector with 20 integer elements
std::vector<int> arr(20);

for(int x = 0; x < 20; ++x)
   arr[x] = x;

If you just want an outer border, the easiest way is to put it in a Border control:

<Border BorderBrush="Black" BorderThickness="2">
    <Grid>
       <!-- Grid contents here -->
    </Grid>
</Border>

The reason you're seeing the border completely fill your control is that, by default, it's HorizontalAlignment and VerticalAlignment are set to Stretch. Try the following:

<Grid>
    <Border  HorizontalAlignment="Left" VerticalAlignment="Top"  BorderBrush="Black" BorderThickness="2">
        <Grid Height="166" HorizontalAlignment="Left" Margin="12,12,0,0" Name="grid1" VerticalAlignment="Top" Width="479" Background="#FFF2F2F2" />
    </Border>
</Grid>

This should get you what you're after (though you may want to put a margin on all 4 sides, not just 2...)

No, there's no direct not operator. At least not the way you hope for.

You can use a zero-width negative lookahead, however:

\((?!2001)[0-9a-zA-z _\.\-:]*\)

The (?!...) part means "only match if the text following (hence: lookahead) this doesn't (hence: negative) match this. But it doesn't actually consume the characters it matches (hence: zero-width).

There are actually 4 combinations of lookarounds with 2 axes:

• lookbehind / lookahead : specifies if the characters before or after the point are considered
• positive / negative : specifies if the characters must match or must not match.

Assuming TARGET variable can be only 'binomial' or 'regression', then following would do:

# Check for modeling types known to this script
if [ $( echo "${TARGET}" | egrep -c "^(binomial|regression)$" ) -eq 0 ]; then
    echo "This scoring program can only handle 'binomial' and 'regression' methods now." >&2
    usage
fi

You could add more strings into the list by separating them with a | (pipe) character.

Advantage of using egrep, is that you could easily add case insensitivity (-i), or check more complex scenarios with a regular expression.

Tested Code:

$("input").css("background","red");

Complete:

$('input:text').focus(function () {
    $(this).css({ 'background': 'Black' });
});

$('input:text').blur(function () {
    $(this).css({ 'background': 'red' });
});

Tested in version:

jquery-1.9.1.js
jquery-ui-1.10.3.js

You should use $(document). It is a function trigger for any click event in the document. Then inside you can use the jquery on("click","body *",somefunction), where the second argument specifies which specific element to target. In this case every element inside the body.

$(document).on('click','body *',function(){
    //  $(this) = your current element that clicked.
    // additional code
});

To install npm on VS Code:

1. Click Ctrl+P
2. Write ext install npm script runner
3. On the results list look for npm 'npm commands for VS Code'. This npm manages commands. Click Install, then Reload VS Code to save changes
4. Restart VS Code
5. On the Integrated Terminal, Run 'npm install'

We have to consider the orientation of device too:

CGFloat screenHeight;
// it is important to do this after presentModalViewController:animated:
if ([[UIApplication sharedApplication] statusBarOrientation] == UIDeviceOrientationPortrait || [[UIApplication sharedApplication] statusBarOrientation] == UIDeviceOrientationPortraitUpsideDown){
    screenHeight = [UIScreen mainScreen].applicationFrame.size.height;
}
else{
    screenHeight = [UIScreen mainScreen].applicationFrame.size.width;
}

Update : As @amram99 mentioned, the issue has been fixed as of the release of Android Studio v1.3.

Tested and verified with below specifications

• Android Studio v1.3
• gradle plugin v1.2.3
• Gradle v2.4

What works now

• Now you can import a local aar file via the File>New>New Module>Import .JAR/.AAR Package option in Android Studio v1.3

• However the below answer holds true and effective irrespective of the Android Studio changes as this is based of gradle scripting.

Old Answer : In a recent update the people at android broke the inclusion of local aar files via the Android Studio's add new module menu option. Check the Issue listed here. Irrespective of anything that goes in and out of IDE's feature list , the below method works when it comes to working with local aar files.(Tested it today):

Put the aar file in the libs directory (create it if needed), then, add the following code in your build.gradle :

dependencies {
   compile(name:'nameOfYourAARFileWithoutExtension', ext:'aar')
 }
repositories{
      flatDir{
              dirs 'libs'
       }
 }

I had to use a separate drawing pass to clear the canvas (lock, draw and unlock):

Canvas canvas = null;
try {
    canvas = holder.lockCanvas();
    if (canvas == null) {
        // exit drawing thread
        break;
    }
    canvas.drawColor(colorToClearFromCanvas, PorterDuff.Mode.CLEAR);
} finally {
    if (canvas != null) {
        holder.unlockCanvasAndPost(canvas);
    }
}

I use highcharts. They are very interactive (and very fancy I might add). You do have to get a little creative to access data from MySQL database, but if you have a general understanding of JavaScript and PHP, you should have no problems.

This is an expansion on Mounir's answer. I've added a bash script that covers this for you. Just run ./scripts/runserver.sh instead of ./manage.py runserver and it'll work exactly the same way.

#!/bin/bash

pid=$(ps aux | grep "./manage.py runserver" | grep -v grep | head -1 | xargs | cut -f2 -d" ")

if [[ -n "$pid" ]]; then
    kill $pid
fi

fuser -k 8000/tcp
./manage.py runserver

I think you can also use MotionEvent.ACTION_UP state, example:

@Override
public boolean onTouch(View v, MotionEvent event) {
    switch (v.getId()) {
    case R.id.iv:
        if (event.getAction() == MotionEvent.ACTION_UP) {
            if (isheadAndFootShow == false) {
                headLayout.setVisibility(View.VISIBLE);
                footLayout.setVisibility(View.VISIBLE);
                isheadAndFootShow = true;
            } else {
                headLayout.setVisibility(View.INVISIBLE);
                footLayout.setVisibility(View.INVISIBLE);
                isheadAndFootShow = false;
            }
            return true;
        }
        break;
    }

    return false;
}

This is being described in this article. Think about forEach of Collections.

List<?> list = …
list.forEach(…);

The forEach isn’t declared by java.util.List nor the java.util.Collection interface yet. One obvious solution would be to just add the new method to the existing interface and provide the implementation where required in the JDK. However, once published, it is impossible to add methods to an interface without breaking the existing implementation.

The benefit that default methods bring is that now it’s possible to add a new default method to the interface and it doesn’t break the implementations.

Swift 3 here's how i do it.

{

import UIKit
import AVFoundation

        let url = Bundle.main.url(forResource: "yoursoundname", withExtension: "wav")!
        do {

            player = try AVAudioPlayer(contentsOf: url); guard let player = player else { return }

            player.prepareToPlay()
            player.play()
        } catch let error as Error {
            print(error)

        }
    }

First of all, this approach won't scale in the large, you'll need a separate index from words to item (like an inverted index).

If your data is not large, you can do

SELECT DISTINCT(name) FROM mytable WHERE name LIKE '%mall%' OR description LIKE '%mall%'

using OR if you have multiple keywords.

There is no built-in method for Node to change the CWD of the underlying shell running the Node process.

You can change the current working directory of the Node process through the command process.chdir().

var process = require('process');
process.chdir('../');

When the Node process exists, you will find yourself back in the CWD you started the process in.

QRGen is a good library that creates a layer on top of ZXing and makes QR Code generation in Java a piece of cake.

It's the array that's causing trouble in:

void print_graph(g_node graph_node[], double weight[][], int nodes);

The second and subsequent dimensions must be given:

void print_graph(g_node graph_node[], double weight[][32], int nodes);

Or you can just give a pointer to pointer:

void print_graph(g_node graph_node[], double **weight, int nodes);

However, although they look similar, those are very different internally.

If you're using C99, you can use variably-qualified arrays. Quoting an example from the C99 standard (section §6.7.5.2 Array Declarators):

void fvla(int m, int C[m][m]); // valid: VLA with prototype scope

void fvla(int m, int C[m][m])  // valid: adjusted to auto pointer to VLA
{

Question in comments

[...] In my main(), the variable I am trying to pass into the function is a double array[][], so how would I pass that into the function? Passing array[0][0] into it gives me incompatible argument type, as does &array and &array[0][0].

In your main(), the variable should be:

double array[10][20];

or something faintly similar; maybe

double array[][20] = { { 1.0, 0.0, ... }, ... };

You should be able to pass that with code like this:

typedef struct graph_node
{
    int X;
    int Y;
    int active;
} g_node;

void print_graph(g_node graph_node[], double weight[][20], int nodes);

int main(void)
{
    g_node g[10];
    double array[10][20];
    int n = 10;

    print_graph(g, array, n);
    return 0;
}

That compiles (to object code) cleanly with GCC 4.2 (i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.9.00)) and also with GCC 4.7.0 on Mac OS X 10.7.3 using the command line:

/usr/bin/gcc -O3 -g -std=c99 -Wall -Wextra -c zzz.c

For LINK elements the content-type is determined in the HTTP-response so the type attribute is superfluous. This is OK for all browsers.

Try this:

$(document).bind("contextmenu",function(e){
    return false;
});

If you want to rename full android package, this is the best way to do that:

1. Mark as checked - Comapct Emty Middle Packages

2. Right click on the packcage you want to change, and then Refactor->Rename->Rename all

You will not be able to retrieve a plain text password from wordpress.

Wordpress use a 1 way encryption to store the passwords using a variation of md5. There is no way to reverse this.

See this article for more info http://wordpress.org/support/topic/how-is-the-user-password-encrypted-wp_hash_password

Very easy trick is using a CSS calc formula. All modern browsers, IE9, wide range of mobile browsers should support this.

<div style='white-space:nowrap'>
  <span style='display:inline-block;width:80px;font-weight:bold'>
    <label for='field1'>Field1</label>
  </span>
  <input id='field1' name='field1' type='text' value='Some text' size='30' style='width:calc(100% - 80px)' />
</div>

use the attribute "innerHTML"

somehow select the table:

var a = document.getElementById('table, div, whatever node, id')
a.innerHTML = your_text

<input type="number" id="xxx" name="xxx" oninput="maxLengthCheck(this)" maxlength="10">

function maxLengthCheck(object) {
  if (object.value.length > object.maxLength)
  object.value = object.value.slice(0, object.maxLength)
}

I use Given-When-Then concept. Take a look at this short article http://cakebaker.42dh.com/2009/05/28/given-when-then/. Article describes this concept in terms of BDD, but you can use it in TDD as well without any changes.

The standard tool for listing symbols is nm, you can use it simply like this:

nm -gD yourLib.so

If you want to see symbols of a C++ library, add the "-C" option which demangle the symbols (it's far more readable demangled).

nm -gDC yourLib.so

If your .so file is in elf format, you have two options:

Either objdump (-C is also useful for demangling C++):

$ objdump -TC libz.so

libz.so:     file format elf64-x86-64

Hmm.

POSIX pthread_exit description from http://pubs.opengroup.org/onlinepubs/009604599/functions/pthread_exit.html:

After a thread has terminated, the result of access to local (auto) variables of the thread is 
undefined. Thus, references to local variables of the exiting thread should not be used for 
the pthread_exit() value_ptr parameter value.

Which seems contrary to the idea that local main() thread variables will remain accessible.

On windows it is easy to interact with your webcam with pygame:

from VideoCapture import Device
cam = Device()
cam.saveSnapshot('image.jpg')

I haven't tried using pygame on linux (all my linux boxen are servers without X), but this link might be helpful http://www.jperla.com/blog/post/capturing-frames-from-a-webcam-on-linux

$final_array = array_combine($a, $a);

Reference: http://php.net/array-combine

P.S. Be careful with source array containing duplicated keys like the following:

$a = ['one','two','one'];

Note the duplicated one element.

And you can combine same events/functions in this way:

$("table.planning_grid").on({
    mouseenter: function() {
        // Handle mouseenter...
    },
    mouseleave: function() {
        // Handle mouseleave...
    },
    'click blur paste' : function() {
        // Handle click...
    }
}, "input");

{{ app.user.username|default('') }}

Just present login username for example, filter function default('') should be nice when user is NOT login by just avoid annoying error message.

I've seen many answers regarding the bootstrap events such as hide.bs.modal which triggers when the modal closes.

There's a problem with those events: any popups in the modal (popovers, tooltips, etc) will trigger that event.

There is another way to catch the event when a modal closes.

$(document).on('hidden','#modal:not(.in)', function(){} );

Bootstrap uses the in class when the modal is open. It is very important to use the hidden event since the class in is still defined when the event hideis triggered.

This solution will not work in IE8 since IE8 does not support the Jquery :not() selector.

FOR MVC

-- WEB.CONFIG CODE IN APP SETTING -- <add key="PhaseLevel" value="1" />

-- ON VIEWS suppose you want to show or hide something based on web.config Value--

-- WRITE THIS ON TOP OF YOUR PAGE-- @{ var phase = System.Configuration.ConfigurationManager.AppSettings["PhaseLevel"].ToString(); }

-- USE ABOVE VALUE WHERE YOU WANT TO SHOW OR HIDE.

@if (phase != "1") { @Html.Partial("~/Views/Shared/_LeftSideBarPartial.cshtml") }

In UWP:

await Launcher.LaunchUriAsync(new Uri("http://google.com"));

Put the following code before int main():

using namespace std;

And you will be able to use cout.

For example:

#include<iostream>
using namespace std;
int main(){
    char t = 'f';
    char *t1;
    char **t2;
    cout<<t;        
    return 0;
}

Now take a moment and read up on what cout is and what is going on here: http://www.cplusplus.com/reference/iostream/cout/

Further, while its quick to do and it works, this is not exactly a good advice to simply add using namespace std; at the top of your code. For detailed correct approach, please read the answers to this related SO question.

Here are some easy way to get you up and running with the XlsxWriter module.The first step is to install the XlsxWriter module.The pip installer is the preferred method for installing Python modules from PyPI, the Python Package Index:

sudo pip install xlsxwriter

Note

Windows users can omit sudo at the start of the command.

with open('writing_file.json', 'w') as w:
    with open('reading_file.json', 'r') as r:

            if 'hours' in element:
                del element['hours']
            w.write(json.dumps(element))

this is the method i use..

go get will install the package in the first directory listed at GOPATH (an environment variable which might contain a colon separated list of directories). You can use go get -u to update existing packages.

You can also use go get -u all to update all packages in your GOPATH

For larger projects, it might be reasonable to create different GOPATHs for each project, so that updating a library in project A wont cause issues in project B.

Type go help gopath to find out more about the GOPATH environment variable.

You can currently do this in a couple of ways.

One is to create guidelines (right-click the design area, then click add vertical/horizontal guideline). You can then click the guideline's "header" to change the positioning to be percentage based. Finally, you can constrain views to guidelines.

Another way is to position a view using bias (percentage) and to then anchor other views to that view.

That said, we have been thinking about how to offer percentage based dimensions. I can't make any promise but it's something we would like to add.

String are immutable, that's why questionText.replace(/[0-9]/g, ''); on it's own does work, but it doesn't change the questionText-string. You'll have to assign the result of the replacement to another String-variable or to questionText itself again.

var cleanedQuestionText = questionText.replace(/[0-9]/g, '');

or in 1 go (using \d+, see Kobi's answer):

 questionText = ("1 ding ?").replace(/\d+/g,'');

and if you want to trim the leading (and trailing) space(s) while you're at it:

 questionText = ("1 ding ?").replace(/\d+|^\s+|\s+$/g,'');

You can use strlen. Size is determined by the terminating null-character, so passed string should be valid.

If you want to get size of memory buffer, that contains your string, and you have pointer to it:

• If it is dynamic array(created with malloc), it is impossible to get it size, since compiler doesn't know what pointer is pointing at. (check this)
• If it is static array, you can use sizeof to get its size.

If you are confused about difference between dynamic and static arrays, check this.

There's typically two levels of buffering involved:

1. Internal buffers
2. Operating system buffers

The internal buffers are buffers created by the runtime/library/language that you're programming against and is meant to speed things up by avoiding system calls for every write. Instead, when you write to a file object, you write into its buffer, and whenever the buffer fills up, the data is written to the actual file using system calls.

However, due to the operating system buffers, this might not mean that the data is written to disk. It may just mean that the data is copied from the buffers maintained by your runtime into the buffers maintained by the operating system.

If you write something, and it ends up in the buffer (only), and the power is cut to your machine, that data is not on disk when the machine turns off.

So, in order to help with that you have the flush and fsync methods, on their respective objects.

The first, flush, will simply write out any data that lingers in a program buffer to the actual file. Typically this means that the data will be copied from the program buffer to the operating system buffer.

Specifically what this means is that if another process has that same file open for reading, it will be able to access the data you just flushed to the file. However, it does not necessarily mean it has been "permanently" stored on disk.

To do that, you need to call the os.fsync method which ensures all operating system buffers are synchronized with the storage devices they're for, in other words, that method will copy data from the operating system buffers to the disk.

Typically you don't need to bother with either method, but if you're in a scenario where paranoia about what actually ends up on disk is a good thing, you should make both calls as instructed.

Addendum in 2018.

Note that disks with cache mechanisms is now much more common than back in 2013, so now there are even more levels of caching and buffers involved. I assume these buffers will be handled by the sync/flush calls as well, but I don't really know.

First you have to download Virtual Box. Then select new and a 32-bit Linux. Then boot the linux using it. If it boots then it is 32 bit if it doesn't then it is a 64 bit.

I solved the problem by enabling the mod_autoindex from Apache. It was disabled by default.

sudo a2enmod autoindex

Set

 Dictionary<int, string> states = new Dictionary<int, string>()

as a property outside the function and inside the function insert the entries, it should work.

The return exits the current function, but the iterations keeps on, so you get the "next" item that skips the if and alerts the 4...

If you need to stop the looping, you should just use a plain for loop like so:

$('button').click(function () {
   var arr = [1, 2, 3, 4, 5];
   for(var i = 0; i < arr.length; i++) {
     var n = arr[i]; 
     if (n == 3) {
         break;
      }
      alert(n);
   })
})

I suggest using vlookup function to get the nearest match.

Step 1

Prepare data range and name it: 'numberRange':

Select the range. Go to menu: Data ? Named ranges... ? define the new named range.

Step 2

Use this simple formula:

=VLOOKUP(A2,numberRange,2)

This way you can ommit errors, and easily correct the result.

A alternative without glib dependency is pkg-config-lite.

Extract pkg-config.exe from the archive and put it in your path.

Nowdays this package is available using chocolatey, then it could be installed whith

choco install pkgconfiglite

The tool that richardtz suggests is excellent.

Another one that is amazing and comes with a 30 day free trial is Araxis Merge. This one does a 3 way merge and is much more feature complete than winmerge, but it is a commercial product.

You might also like to check out Scott Hanselman's developer tool list, which mentions a couple more in addition to winmerge

You'll need to save as a blob, LONGBLOB datatype in mysql will work.

Ex:

CREATE TABLE 'test'.'pic' (
    'idpic' INTEGER UNSIGNED NOT NULL AUTO_INCREMENT,
    'caption' VARCHAR(45) NOT NULL,
    'img' LONGBLOB NOT NULL,
  PRIMARY KEY ('idpic')
)

As others have said, its a bad practice but it can be done. Not sure if this code would scale well, though.

I think you are confused about how the compiler puts things together. When you use -c flag, i.e. no linking is done, the input is C++ code, and the output is object code. The .o files thus don't mix with -c, and compiler warns you about that. Symbols from object file are not moved to other object files like that.

All object files should be on the final linker invocation, which is not the case here, so linker (called via g++ front-end) complains about missing symbols.

Here's a small example (calling g++ explicitly for clarity):

PROG ?= myprog
OBJS = worker.o main.o

all: $(PROG)

.cpp.o:
        g++ -Wall -pedantic -ggdb -O2 -c -o $@ $<

$(PROG): $(OBJS)
        g++ -Wall -pedantic -ggdb -O2 -o $@ $(OBJS)

There's also makedepend utility that comes with X11 - helps a lot with source code dependencies. You might also want to look at the -M gcc option for building make rules.

I had a similar error but with different context when I uploaded a *.p file to Google Drive. I tried to use it later in a Google Colab session, and got this error:

    1 with open("/tmp/train.p", mode='rb') as training_data:
----> 2     train = pickle.load(training_data)
UnpicklingError: invalid load key, '<'.

I solved it by compressing the file, upload it and then unzip on the session. It looks like the pickle file is not saved correctly when you upload/download it so it gets corrupted.

Another Python BST with sort key (defaulting to value)

LEFT = 0
RIGHT = 1
VALUE = 2
SORT_KEY = -1

class BinarySearchTree(object):

    def __init__(self, sort_key=None):
        self._root = []  
        self._sort_key = sort_key
        self._len = 0  

def insert(self, val):
    if self._sort_key is None:
        sort_key = val // if no sort key, sort key is value
    else:
        sort_key = self._sort_key(val)

    node = self._root
    while node:
        if sort_key < node[_SORT_KEY]:
            node = node[LEFT]
        else:
            node = node[RIGHT]

    if sort_key is val:
        node[:] = [[], [], val]
    else:
        node[:] = [[], [], val, sort_key]
    self._len += 1

def minimum(self):
    return self._extreme_node(LEFT)[VALUE]

def maximum(self):
    return self._extreme_node(RIGHT)[VALUE]

def find(self, sort_key):
    return self._find(sort_key)[VALUE]

def _extreme_node(self, side):
    if not self._root:
        raise IndexError('Empty')
    node = self._root
    while node[side]:
        node = node[side]
    return node

def _find(self, sort_key):
    node = self._root
    while node:
        node_key = node[SORT_KEY]
        if sort_key < node_key:
            node = node[LEFT]
        elif sort_key > node_key:
            node = node[RIGHT]
        else:
            return node
    raise KeyError("%r not found" % sort_key)

If you have a lot of binary data to read, you might want to consider the struct module. It is documented as converting "between C and Python types", but of course, bytes are bytes, and whether those were created as C types does not matter. For example, if your binary data contains two 2-byte integers and one 4-byte integer, you can read them as follows (example taken from struct documentation):

>>> struct.unpack('hhl', b'\x00\x01\x00\x02\x00\x00\x00\x03')
(1, 2, 3)

You might find this more convenient, faster, or both, than explicitly looping over the content of a file.

Try something like this:

var node=document.createElement("LI");
var textnode=document.createTextNode(firstname);
node.appendChild(textnode);
document.getElementById("demo").appendChild(node);

As @Darin Dimitrov said, if it is not an iframe on the same domain it is not posible, if it is, check that $("#frame1").contents() returns all it should, and then check if the textbox is found:

$("#frame1").contents().find("#area1").length should be 1.

Edit

If when your textarea is "empty" an empty string is returned and when it has some text entered that text is returned, then it is working perfect!! When the textarea is empty, an empty string is returned!

Edit 2 Ok. Here there is one way, it is not very pretty but it works:

Outside the iframe you will access the textarea like this:

window.textAreaInIframe

And inside the iframe (which I assume has jQuery) in the document ready put this code:

$("#area1").change(function() {
    window.parent.textAreaInIframe = $(this).val();
}).trigger("change");

function _settimezone($time,$defaultzone,$newzone)
{
$date = new DateTime($time, new DateTimeZone($defaultzone));
$date->setTimezone(new DateTimeZone($newzone));
$result=$date->format('Y-m-d H:i:s');
return $result;
}

$defaultzone="UTC";
$newzone="America/New_York";
$time="2011-01-01 15:00:00";
$newtime=_settimezone($time,$defaultzone,$newzone);

Just return any kind of list. ArrayList will be fine, its not static.

    ArrayList<yourClass> list = new ArrayList<yourClass>();
for (yourClass item : yourArray) 
{
   list.add(item); 
}

A quick and dirty solution I have used is to place the EditText inside of a FrameLayout. The margins of the EditText control the thickness of the border and the border color is determined by the background color of the FrameLayout.

Example:

<FrameLayout
    android:id="@+id/frameLayout"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="#000000">

    <EditText
        android:id="@+id/editText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="3dp"
        android:background="@android:color/white"
        android:ems="10"
        android:inputType="text"
        android:textSize="24sp" />
</FrameLayout>

But I would recommend, and the vast majority of the time I do, drawables for borders. Elite's answer is what I would go for in that case.
