Below code for best examples for nested loops, while using two for loops please remember the output of the first loop is input for the second loop. Loop termination also important while using the nested loops

for x in range(1, 10, 1):
     for y in range(1,x):
             print y,
        print
OutPut :
1
1 2
1 2 3
1 2 3 4
1 2 3 4 5
1 2 3 4 5 6
1 2 3 4 5 6 7
1 2 3 4 5 6 7 8

You can also refactor your code to use a generator. But this may not be a solution for all types of nested loops.

Don't quote me on this, but you could use goto as suggested in the MSDN. There are other solutions, as including a flag that is checked in each iteration of both loops. Finally you could use an exception as a really heavyweight solution to your problem.

GOTO:

for ( int i = 0; i < 10; ++i ) {
   for ( int j = 0; j < 10; ++j ) {
      // code
      if ( break_condition ) goto End;
      // more code
   }
}
End: ;

Condition:

bool exit = false;
for ( int i = 0; i < 10 && !exit; ++i ) {
   for ( int j = 0; j < 10 && !exit; ++j ) {
      // code
      if ( break_condition ) {
         exit = true;
         break; // or continue
      }
      // more code
   }
}

Exception:

try {
    for ( int i = 0; i < 10 && !exit; ++i ) {
       for ( int j = 0; j < 10 && !exit; ++j ) {
          // code
          if ( break_condition ) {
             throw new Exception()
          }
          // more code
       }
    }
catch ( Exception e ) {}

I was looking for a solution to enumerate an array of an unknown at compile time rank with an access to every element indices set. I saw solutions with yield but here is another implementation with no yield. It is in old school minimalistic way. In this example AppendArrayDebug() just prints all the elements into StringBuilder buffer.

public static void AppendArrayDebug ( StringBuilder sb, Array array )
{
    if( array == null || array.Length == 0 )
    {
        sb.Append( "<nothing>" );
        return;
    }

    int i;

    var rank = array.Rank;
    var lastIndex = rank - 1;

    // Initialize indices and their boundaries
    var indices = new int[rank];
    var lower = new int[rank];
    var upper = new int[rank];
    for( i = 0; i < rank; ++i )
    {
        indices[i] = lower[i] = array.GetLowerBound( i );
        upper[i] = array.GetUpperBound( i );
    }

    while( true )
    {
        BeginMainLoop:

        // Begin work with an element

        var element = array.GetValue( indices );

        sb.AppendLine();
        sb.Append( '[' );
        for( i = 0; i < rank; ++i )
        {
            sb.Append( indices[i] );
            sb.Append( ' ' );
        }
        sb.Length -= 1;
        sb.Append( "] = " );
        sb.Append( element );

        // End work with the element

        // Increment index set

        // All indices except the first one are enumerated several times
        for( i = lastIndex; i > 0; )
        {
            if( ++indices[i] <= upper[i] )
                goto BeginMainLoop;
            indices[i] = lower[i];
            --i;
        }

        // Special case for the first index, it must be enumerated only once
        if( ++indices[0] > upper[0] )
            break;
    }
}

For example the following array will produce the following output:

var array = new [,,]
{
    { {  1,  2,  3 }, {  4,  5,  6 }, {  7,  8,  9 }, { 10, 11, 12 } },
    { { 13, 14, 15 }, { 16, 17, 18 }, { 19, 20, 21 }, { 22, 23, 24 } }
};

/*
Output:

[0 0 0] = 1
[0 0 1] = 2
[0 0 2] = 3
[0 1 0] = 4
[0 1 1] = 5
[0 1 2] = 6
[0 2 0] = 7
[0 2 1] = 8

[0 3 0] = 10

[1 2 0] = 19

[1 2 2] = 21
[1 3 0] = 22
[1 3 1] = 23
[1 3 2] = 24
*/

I thought I'd show a functional-programming approach. You can break out of nested Array.prototype.some() and/or Array.prototype.every() functions, as in my solutions. An added benefit of this approach is that Object.keys() enumerates only an object's own enumerable properties, whereas "a for-in loop enumerates properties in the prototype chain as well".

Close to the OP's solution:

    Args.forEach(function (arg) {
        // This guard is not necessary,
        // since writing an empty string to document would not change it.
        if (!getAnchorTag(arg))
            return;

        document.write(getAnchorTag(arg));
    });

    function getAnchorTag (name) {
        var res = '';

        Object.keys(Navigation.Headings).some(function (Heading) {
            return Object.keys(Navigation.Headings[Heading]).some(function (Item) {
                if (name == Navigation.Headings[Heading][Item].Name) {
                    res = ("<a href=\""
                                 + Navigation.Headings[Heading][Item].URL + "\">"
                                 + Navigation.Headings[Heading][Item].Name + "</a> : ");
                    return true;
                }
            });
        });

        return res;
    }

Solution that reduces iterating over the Headings/Items:

    var remainingArgs = Args.slice(0);

    Object.keys(Navigation.Headings).some(function (Heading) {
        return Object.keys(Navigation.Headings[Heading]).some(function (Item) {
            var i = remainingArgs.indexOf(Navigation.Headings[Heading][Item].Name);

            if (i === -1)
                return;

            document.write("<a href=\""
                                         + Navigation.Headings[Heading][Item].URL + "\">"
                                         + Navigation.Headings[Heading][Item].Name + "</a> : ");
            remainingArgs.splice(i, 1);

            if (remainingArgs.length === 0)
                return true;
            }
        });
    });

One one line (semi-colons necessary):

for i in 0 1 2 3 4 5 6 7 8 9; do for j in 0 1 2 3 4 5 6 7 8 9; do echo "$i$j"; done; done

Formatted for legibility (no semi-colons needed):

for i in 0 1 2 3 4 5 6 7 8 9
do
    for j in 0 1 2 3 4 5 6 7 8 9
    do 
        echo "$i$j"
    done
done

There are different views on how the shell code should be laid out over multiple lines; that's about what I normally use, unless I put the next operation on the same line as the do (saving two lines here).

Another way of reducing your iteration to a single-level loop would be via the use of generators as also specified in the python reference

for i, j in ((i, j) for i in A for j in B):
    print(i , j)
    if (some_condition):
        break

You could scale it up to any number of levels for the loop

The downside is that you can no longer break only a single level. It's all or nothing.

Another downside is that it doesn't work with a while loop. I originally wanted to post this answer on Python - `break` out of all loops but unfortunately that's closed as a duplicate of this one

For i As Integer = 0 To 100
    bool = False
    For j As Integer = 0 To 100
        If check condition Then
            'if condition match
            bool = True
            Exit For 'Continue For
        End If
    Next
    If bool = True Then Continue For
Next

One way is to put all the nested loops into a function and return from the inner most loop incase of a need to break out of all loops.

function() 
{    
  for(int i=0; i<1000; i++)
  {
   for(int j=0; j<1000;j++)
   {
      if (condition)
        return;
   }
  }    
}

Break 1st loop:

for(i=0;i<5;i++)
{
  for(j=i+1;j<5;j++)
  {
    //do something

    break;
  }
  alert(1);
};

Break both loops:

for(i=0;i<5;i++)
{
  var breakagain = false;
  for(j=i+1;j<5;j++)
  {
    //do something

    breakagain = true;
    break;
  }
  alert(1);
  if(breakagain)
    break;
};

The break statement terminates the execution of the nearest enclosing do, for, switch, or while statement in which it appears. Control passes to the statement that follows the terminated statement.

from msdn.

Check if the inner loop is exited with an if statement, by checking the inner loop's variable. You could also create another variable such as a boolean to check if the inner loop is exited.

In this example it uses the inner loop's variable to check if it has been exited:

int i, j;
for(i = 0; i < 7; i++){

for(j = 0; j < 5; j++) {

     if (some condition) {
         // Do something and break...
         break; // Breaks out of the inner loop
     }
}
     if(j < 5){    // Checks if inner loop wasn't finished
     break;    // Breaks out of the outer loop   
     } 
}

sudo mv /filename /etc/init.d/
sudo chmod +x /etc/init.d/filename 
sudo update-rc.d filename defaults 

Script should now start on boot. Note that this method also works with both hard links and symbolic links (ln).

Edit

At this point in the boot process PATH isn't set yet, so it is critical that absolute paths are used throughout. BUT, as pointed out in the comments by Steve HHH, explicitly declaring the full file path (/etc/init.d/filename) for the update-rc.d command is not valid in most versions of Linux. Per the manpage for update-rc.d, the second parameter is a script located in /etc/init.d/*. Updated above code to reflect this.

Another Edit

Also as pointed out in the comments (by Charles Brandt), /filename must be an init style script. A good template was also provided - https://github.com/fhd/init-script-template.

Another link to another article just to avoid possible link rot (although it would be saddening if GitHub died) - http://www.linux.com/learn/tutorials/442412-managing-linux-daemons-with-init-scripts

yetAnother Edit

As pointed out in the comments (by Russell Yan), This works only on default mode of update-rc.d.

According to manual of update-rc.d, it can run on two modes, "the machines using the legacy mode will have a file /etc/init.d/.legacy-bootordering", in which case you have to pass sequence and runlevel configuration through command line arguments.

The equivalent argument set for the above example is

sudo update-rc.d filename start 20 2 3 4 5 . stop 20 0 1 6 .

If you use Spring Boot, you can configure Jackson globally as follows:

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import org.springframework.boot.autoconfigure.jackson.Jackson2ObjectMapperBuilderCustomizer;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.converter.json.Jackson2ObjectMapperBuilder;

@Configuration
public class JacksonObjectMapperConfiguration implements Jackson2ObjectMapperBuilderCustomizer {

    @Override
    public void customize(Jackson2ObjectMapperBuilder jacksonObjectMapperBuilder) {
        jacksonObjectMapperBuilder.visibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.NONE);
        jacksonObjectMapperBuilder.visibility(PropertyAccessor.FIELD, JsonAutoDetect.Visibility.ANY);
        jacksonObjectMapperBuilder.visibility(PropertyAccessor.CREATOR, JsonAutoDetect.Visibility.ANY);
    }

}

The difference is that Visibility.Hidden hides the control, but reserves the space it occupies in the layout. So it renders whitespace instead of the control. Visibilty.Collapsed does not render the control and does not reserve the whitespace. The space the control would take is 'collapsed', hence the name.

The exact text from the MSDN:

Collapsed: Do not display the element, and do not reserve space for it in layout.

Hidden: Do not display the element, but reserve space for the element in layout.

Visible: Display the element.

See: http://msdn.microsoft.com/en-us/library/system.windows.visibility.aspx

I tried all the above solutions, however none of them worked. If you're on linux/macOS i highly suggest using tsocks over an ssh tunnel. What you need in order to get this setup working is a machine where you can log in via ssh, and in addition to that a programm called tsocks installed.

The idea here is to create a dynamic tunnel via SSH (a socks5 proxy). We then configure tsocks to use this tunnel and to start our applications, in this case:

tsocks gem install ...

or to account for rails 3.0:

tsocks bundle install

A more detailed guide can be found under:

http://blog.byscripts.info/2011/04/bypass-a-proxy-with-ssh-tunnel-and-tsocks-under-ubuntu/

Despite being written for Ubuntu the procedure should be applicable for all Unix based machines. An alternative to tsocks for Windows is FreeCap (http://www.freecap.ru/eng/). A viable SSH client on windows is called putty.

If you are injecting something that needs the script tag, you may get an uncaught syntax error and say illegal token. To avoid this, be sure to escape the forward slashes in your closing script tag(s). ie;

var output += '<\/script>';

Same goes for any closing tags, such as a form tag.

I even run the command prompt as Administrator but it didn't work for me with the below error.

'keytool' is not recognized as an internal or external command,
 operable program or batch file.

If the path to the keytool is not in your System paths then you will need to use the full path to use the keytool, which is

C:\Program Files\Java\jre<version>\bin

So, the command should be like

"C:\Program Files\Java\jre<version>\bin\keytool.exe" -importcert -alias certificateFileAlias -file CertificateFileName.cer -keystore cacerts

that worked for me.

This error can also occur when opening a Silverlight project that was built in SL 4, while you have SL 5 installed.

Here is an example error message: The imported project "C:\Program Files (x86)\MSBuild\Microsoft\Silverlight\v4.0\Microsoft.Silverlight.CSharp.targets" was not found.

Note the v4.0.

To resolve, edit the project and find:

<TargetFrameworkVersion>v4.0</TargetFrameworkVersion>

And change it to v5.0.

Then reload project and it will open (unless you do not have SL 5 installed).

Although other answers include some of the following information, this is the absolute minimum that needs to be changed on EC2 instances, specifically regarding deployment of large WAR files, and is the least likely to cause issues during future updates. I've been running into these limits about every other year due to the ever-increasing size of the Jenkins WAR file (now ~72MB).

More specifically, this answer is applicable if you encounter a variant of the following error in catalina.out:

SEVERE [https-jsse-nio-8443-exec-17] org.apache.catalina.core.ApplicationContext.log HTMLManager:
FAIL - Deploy Upload Failed, Exception:
[org.apache.tomcat.util.http.fileupload.FileUploadBase$SizeLimitExceededException:
the request was rejected because its size (75333656) exceeds the configured maximum (52428800)]

On Amazon EC2 Linux instances, the only file that needs to be modified from the default installation of Tomcat (sudo yum install tomcat8) is:

/usr/share/tomcat8/webapps/manager/WEB-INF/web.xml

By default, the maximum upload size is exactly 50MB:

<multipart-config>
  <!-- 50MB max -->
  <max-file-size>52428800</max-file-size>
  <max-request-size>52428800</max-request-size>
  <file-size-threshold>0</file-size-threshold>
</multipart-config>

There are only two values that need to be modified (max-file-size and max-request-size):

<multipart-config>
  <!-- 100MB max -->
  <max-file-size>104857600</max-file-size>
  <max-request-size>104857600</max-request-size>
  <file-size-threshold>0</file-size-threshold>
</multipart-config>

When Tomcat is upgraded on these instances, the new version of the manager web.xml will be placed in web.xml.rpmnew, so any modifications to the original file will not be overwritten during future updates.

It normally represents a parameter to be supplied by client.

The simplest way to add color programmatically is by using ColorLiteral.

Just add the property ColorLiteral as shown in the example, Xcode will prompt you with a whole list of colors which you can choose. The advantage of doing so is lesser code, add HEX values or RGB. You will also get the recently used colors from the storyboard.

Example: self.view.backgroundColor = ColorLiteral

For ansible, and using hyphen, this worked for me:

    - name: free-ud-ssd-space-in-percent
      debug:
        var: clusterInfo.json.content["free-ud-ssd-space-in-percent"]

This is the way I prefer:

class Klass(object):

    @staticmethod
    def stat_func():
        return 42

    _ANS = stat_func.__func__()

    def method(self):
        return self.__class__.stat_func() + self.__class__._ANS

I prefer this solution to Klass.stat_func, because of the DRY principle. Reminds me of the reason why there is a new super() in Python 3 :)

But I agree with the others, usually the best choice is to define a module level function.

For instance with @staticmethod function, the recursion might not look very good (You would need to break DRY principle by calling Klass.stat_func inside Klass.stat_func). That's because you don't have reference to self inside static method. With module level function, everything will look OK.

I listened to that podcast, and it was amusing, but the security argument made no sense to me. If you've compromised server A, and that server can access data on server B, then you instantly have access to the data on server B.

Slightly related, I was looking for the unique combinations and I came up with this method:

def unique_columns(df,columns):

    result = pd.Series(index = df.index)

    groups = meta_data_csv.groupby(by = columns)
    for name,group in groups:
       is_unique = len(group) == 1
       result.loc[group.index] = is_unique

    assert not result.isnull().any()

    return result

And if you only want to assert that all combinations are unique:

df1.set_index(['A','B']).index.is_unique

Yes.

  Field f = Test.class.getDeclaredField("str");
  f.setAccessible(true);//Very important, this allows the setting to work.
  String value = (String) f.get(object);

Then you use the field object to get the value on an instance of the class.

Note that get method is often confusing for people. You have the field, but you don't have an instance of the object. You have to pass that to the get method

The plyr package can be used for this. With the ddply() function you can split a data frame on one or more columns and apply a function and return a data frame, then with the summarize() function you can use the columns of the splitted data frame as variables to make the new data frame/;

dat <- read.table(textConnection('Group Score Info
1     1     1    a
2     1     2    b
3     1     3    c
4     2     4    d
5     2     3    e
6     2     1    f'))

library("plyr")

ddply(dat,.(Group),summarize,
    Max = max(Score),
    Info = Info[which.max(Score)])
  Group Max Info
1     1   3    c
2     2   4    d

And another way:

<a href="javascript:history.back()">Go Back</a>

If you want it to be truly dynamic and select the radio that corresponds to the incoming data, this works. It's using the gender value of the data passed in or uses default.

if(data['gender'] == ''){
 $('input:radio[name="gender"][value="Male"]').prop('checked', true);
}else{
  $('input:radio[name="gender"][value="' + data['gender'] +'"]').prop('checked', true);
};

When it comes to Swift Frameworks. As for today, with Xcode version 6.1.1 (6A2008a), if the Swift framework is targeted to iOS 7.1, linker report warning

ld: warning: embedded dylibs/frameworks only run on iOS 8 or later.

and application can't be submitted to AppStore. Check this issue : Lint to prevent dynamic libraries and frameworks from passing with iOS 7

You could also use a StringVar variable, even if it's not strictly necessary:

v = StringVar()

e = Entry(master, textvariable=v)
e.pack()

v.set("a default value")
s = v.get()

For more information, see this page on effbot.org.

For me the problem was my regex expression. The below did the trick to get bootstrap working:

{
    test: /\.(woff|ttf|eot|svg)(\?v=[a-z0-9]\.[a-z0-9]\.[a-z0-9])?$/,
    loader: 'url-loader?limit=100000'
},

You can use MGET to get the values of multiple keys in a single go.

Example:

redis> SET key1 "Hello"
"OK"
redis> SET key2 "World"
"OK"
redis> MGET key1 key2 nonexisting
1) "Hello"
2) "World"
3) (nil)

For listing out all keys & values you'll probably have to use bash or something similar, but MGET can help in listing all the values when you know which keys to look for beforehand.

Beware that calling Sleep() will freeze the service, so if the service is requested to stop, it won't react for the duration of the Sleep() call.

This returns the number of difference in seconds of the given date and the $date.so you are getting wrong result .

Suppose $date is todays date and -1 day means it returns -86400 as the difference and the when you try using date you will get 1969-12-31 Unix timestamp start date.

This is an Oracle-specific notation for an outer join. It means that it will include all rows from t1, and use NULLS in the t0 columns if there is no corresponding row in t0.

In standard SQL one would write:

SELECT t0.foo, t1.bar
  FROM FIRST_TABLE t0
 RIGHT OUTER JOIN SECOND_TABLE t1;

Oracle recommends not to use those joins anymore if your version supports ANSI joins (LEFT/RIGHT JOIN) :

Oracle recommends that you use the FROM clause OUTER JOIN syntax rather than the Oracle join operator. Outer join queries that use the Oracle join operator (+) are subject to the following rules and restrictions […]

When you use Task.Run to run a method, Task gets a thread from threadpool to run that method. So from the UI thread's perspective, it is "asynchronous" as it doesn't block UI thread.This is fine for desktop application as you usually don't need many threads to take care of user interactions.

However, for web application each request is serviced by a thread-pool thread and thus the number of active requests can be increased by saving such threads. Frequently using threadpool threads to simulate async operation is not scalable for web applications.

True Async doesn't necessarily involving using a thread for I/O operations, such as file / DB access etc. You can read this to understand why I/O operation doesn't need threads. http://blog.stephencleary.com/2013/11/there-is-no-thread.html

In your simple example,it is a pure CPU-bound calculation, so using Task.Run is fine.

my @badparams = (1,2,5,7,'a','zzz');

my $badparams = join('|',@badparams);   # '|' or any other character not present in params

foreach my $par (4,5,6,7,'a','z','zzz')
{
    if ($badparams =~ /\b$par\b/)
    {
        print "$par is present\n";
    }
    else
    {
        print "$par is not present\n";
    }
}

You may want to check for numerical leading spaces consistancy

As for me here the most easily way to add text(Tab -> \t) in textarea by cursor position and save the focus on cursor:

$('#text').keyup(function () {
    var cursor = $('#text').prop('selectionStart');
    //if cursot is first in textarea
    if (cursor == 0) {
        //i will add tab in line
        $('#text').val('\t' + $('#text').val());
        //here we set the cursor position
        $('#text').prop('selectionEnd', 1);
    } else {
        var value = $('#text').val();
        //save the value before cursor current position
        var valToCur = value.substring(0, cursor);
        //save the value after cursor current position
        var valAfter = value.substring(cursor, value.length);
        //save the new value with added tab in text
        $('#text').val(valToCur + '\t' + valAfter);
        //set focus of cursot after insert text (1 = because I add only one symbol)
        $('#text').prop('selectionEnd', cursor + 1);
    }
});

Can be done in major new broswers using the code below

.img {
    -webkit-filter:invert(100%);
     filter:progid:DXImageTransform.Microsoft.BasicImage(invert='1');
}

However, if you want it to work across all browsers you need to use Javascript. Something like this gist will do the job.

There is a way to skip the errors inside the code and go on with the loop anyway, hope it helps:

Sub new1()

Dim wsFunc As WorksheetFunction: Set wsFunc = Application.WorksheetFunction
Dim ws As Worksheet: Set ws = Sheets(1)
Dim rngLook As Range: Set rngLook = ws.Range("A:M")

currName = "Example"
On Error Resume Next ''if error, the code will go on anyway
cellNum = wsFunc.VLookup(currName, rngLook, 13, 0)

If Err.Number <> 0 Then
''error appeared
    MsgBox "currName not found" ''optional, no need to do anything
End If

On Error GoTo 0 ''no error, coming back to default conditions

End Sub

An alternative to theme_classic() is the theme that comes with the cowplot package, theme_cowplot() (loaded automatically with the package). It looks similar to theme_classic(), with a few subtle differences. Most importantly, the default label sizes are larger, so the resulting figures can be used in publications without further modifications needed (in particular if you save them with save_plot() instead of ggsave()). Also, the background is transparent, not white, which may be useful if you want to edit the figure in illustrator. Finally, faceted plots look better, in my opinion.

Example:

library(cowplot)
a <- seq(1,20)
b <- a^0.25
df <- as.data.frame(cbind(a,b))

p <- ggplot(df, aes(x = a, y = b)) + geom_point()
save_plot('plot.png', p) # alternative to ggsave, with default settings that work well with the theme

This is what the file plot.png produced by this code looks like:

My 2 cents - it makes sense to use WITH (NOLOCK) when you need to generate reports. At this point, the data wouldn't change much & you wouldn't want to lock those records.

Here's a one-liner (imports don't count :) that can easily be generalized to concatenate N dictionaries:

Python 3

from itertools import chain
dict(chain.from_iterable(d.items() for d in (d1, d2, d3)))

and:

from itertools import chain
def dict_union(*args):
    return dict(chain.from_iterable(d.items() for d in args))

Python 2.6 & 2.7

from itertools import chain
dict(chain.from_iterable(d.iteritems() for d in (d1, d2, d3))

Output:

>>> from itertools import chain
>>> d1={1:2,3:4}
>>> d2={5:6,7:9}
>>> d3={10:8,13:22}
>>> dict(chain.from_iterable(d.iteritems() for d in (d1, d2, d3)))
{1: 2, 3: 4, 5: 6, 7: 9, 10: 8, 13: 22}

Generalized to concatenate N dicts:

from itertools import chain
def dict_union(*args):
    return dict(chain.from_iterable(d.iteritems() for d in args))

I'm a little late to this party, I know, but I hope this helps someone.

You can use a transformation for your data frame:

df = pd.DataFrame(my_data condition)

transforming True/False in 1/0

df = df*1

From the documentation:

__file__ is the pathname of the file from which the module was loaded, if it was loaded from a file. The __file__ attribute is not present for C modules that are statically linked into the interpreter; for extension modules loaded dynamically from a shared library, it is the pathname of the shared library file.

From the mailing list thread linked by @kindall in a comment to the question:

I haven't tried to repro this particular example, but the reason is that we don't want to have to call getpwd() on every import nor do we want to have some kind of in-process variable to cache the current directory. (getpwd() is relatively slow and can sometimes fail outright, and trying to cache it has a certain risk of being wrong.)

What we do instead, is code in site.py that walks over the elements of sys.path and turns them into absolute paths. However this code runs before '' is inserted in the front of sys.path, so that the initial value of sys.path is ''.

For the rest of this, consider sys.path not to include ''.

So, if you are outside the part of sys.path that contains the module, you'll get an absolute path. If you are inside the part of sys.path that contains the module, you'll get a relative path.

If you load a module in the current directory, and the current directory isn't in sys.path, you'll get an absolute path.

If you load a module in the current directory, and the current directory is in sys.path, you'll get a relative path.

The problem could be that the Python libraries, per HTTP-Standard, first send an unauthenticated request, and then only if it's answered with a 401 retry, are the correct credentials sent. If the Foursquare servers don't do "totally standard authentication" then the libraries won't work.

Try using headers to do authentication:

import urllib2, base64

request = urllib2.Request("http://api.foursquare.com/v1/user")
base64string = base64.b64encode('%s:%s' % (username, password))
request.add_header("Authorization", "Basic %s" % base64string)   
result = urllib2.urlopen(request)

Had the same problem as you and found the solution from this thread: http://forums.shopify.com/categories/9/posts/27662

$timeFirst  = strtotime('2011-05-12 18:20:20');
$timeSecond = strtotime('2011-05-13 18:20:20');
$differenceInSeconds = $timeSecond - $timeFirst;

You will then be able to use the seconds to find minutes, hours, days, etc.

remember to set you username and password if required:

http://USERNAME:[email protected]:8080

Example:

npm config set proxy http://USERNAME:[email protected]:8080

For me it worked:

function changeA2 () { $global:A="0"}
changeA2

In Rails 4.1.0, I have faced problem with saving latitude and longitude to MySql database. It can't save large fraction number with float data type. And I change the data type to decimal and working for me.

  def change
    change_column :cities, :latitude, :decimal, :precision => 15, :scale => 13
    change_column :cities, :longitude, :decimal, :precision => 15, :scale => 13
  end

There's more than one way to do this obviously.

    # This will find files recursively (you can limit it by using some 'find' parameters. 
    # see the man pages
    # Final backslash required for exec example to work
    find . -name '*.gz' -exec gunzip '{}' \;

    # This will do it only in the current directory
    for a in *.gz; do gunzip $a; done

I'm sure there's other ways as well, but this is probably the simplest.

And to remove it, just do a rm -rf *.gz in the applicable directory

Given that Windows has no sys/socket.h, you might consider just doing something like this:

#ifdef __WIN32__
# include <winsock2.h>
#else
# include <sys/socket.h>
#endif

I know you indicated that you won't use WinSock, but since WinSock is how TCP networking is done under Windows, I don't see that you have any alternative. Even if you use a cross-platform networking library, that library will be calling WinSock internally. Most of the standard BSD sockets API calls are implemented in WinSock, so with a bit of futzing around, you can make the same sockets-based program compile under both Windows and other OS's. Just don't forget to do a

#ifdef __WIN32__
   WORD versionWanted = MAKEWORD(1, 1);
   WSADATA wsaData;
   WSAStartup(versionWanted, &wsaData);
#endif

at the top of main()... otherwise all of your socket calls will fail under Windows, because the WSA subsystem wasn't initialized for your process.

I took a look at the datejs and stripped out the code necessary to add months to a date handling edge cases (leap year, shorter months, etc):

Date.isLeapYear = function (year) { 
    return (((year % 4 === 0) && (year % 100 !== 0)) || (year % 400 === 0)); 
};

Date.getDaysInMonth = function (year, month) {
    return [31, (Date.isLeapYear(year) ? 29 : 28), 31, 30, 31, 30, 31, 31, 30, 31, 30, 31][month];
};

Date.prototype.isLeapYear = function () { 
    return Date.isLeapYear(this.getFullYear()); 
};

Date.prototype.getDaysInMonth = function () { 
    return Date.getDaysInMonth(this.getFullYear(), this.getMonth());
};

Date.prototype.addMonths = function (value) {
    var n = this.getDate();
    this.setDate(1);
    this.setMonth(this.getMonth() + value);
    this.setDate(Math.min(n, this.getDaysInMonth()));
    return this;
};

This will add "addMonths()" function to any javascript date object that should handle edge cases. Thanks to Coolite Inc!

Use:

var myDate = new Date("01/31/2012");
var result1 = myDate.addMonths(1);

var myDate2 = new Date("01/31/2011");
var result2 = myDate2.addMonths(1);

->> newDate.addMonths -> mydate.addMonths

result1 = "Feb 29 2012"

result2 = "Feb 28 2011"

You're getting this error because you're failing client authentication. Based on the error message, you probably have the default postgres configuration, which sets client authentication method to "IDENT" for all PostgreSQL connections.

You should definitely read section 19.1 Client Authentication in the PostgreSQL manual to better understand the authentication settings available (for each record in pg_hba.conf), but here is the relevant snippet to help with the problem you're having (from the version 9.5 manual):

trust

Allow the connection unconditionally. This method allows anyone that can connect to the PostgreSQL database server to login as any PostgreSQL user they wish, without the need for a password or any other authentication. See Section 19.3.1 for details.

reject

Reject the connection unconditionally. This is useful for "filtering out" certain hosts from a group, for example a reject line could block a specific host from connecting, while a later line allows the remaining hosts in a specific network to connect.

md5

Require the client to supply a double-MD5-hashed password for authentication. See Section 19.3.2 for details.

password

Require the client to supply an unencrypted password for authentication. Since the password is sent in clear text over the network, this should not be used on untrusted networks. See Section 19.3.2 for details.

gss

Use GSSAPI to authenticate the user. This is only available for TCP/IP connections. See Section 19.3.3 for details.

sspi

Use SSPI to authenticate the user. This is only available on Windows. See Section 19.3.4 for details.

ident

Obtain the operating system user name of the client by contacting the ident server on the client and check if it matches the requested database user name. Ident authentication can only be used on TCP/IP connections. When specified for local connections, peer authentication will be used instead. See Section 19.3.5 for details.

peer

Obtain the client's operating system user name from the operating system and check if it matches the requested database user name. This is only available for local connections. See Section 19.3.6 for details.

ldap

Authenticate using an LDAP server. See Section 19.3.7 for details.

radius

Authenticate using a RADIUS server. See Section 19.3.8 for details.

cert

Authenticate using SSL client certificates. See Section 19.3.9 for details.

pam

Authenticate using the Pluggable Authentication Modules (PAM) service provided by the operating system. See Section 19.3.10 for details.

So ... to solve the problem you're experiencing, you could do one of the following:

1. Change the authentication method(s) defined in your pg_hba.conf file to trust, md5, or password (depending on your security and simplicity needs) for the local connection records you have defined in there.

2. Update pg_ident.conf to map your operating system users to PostgreSQL users and grant them the corresponding access privileges, depending on your needs.

3. Leave the IDENT settings alone and create users in your database for each operating system user that you want to grant access to. If a user is already authenticated by the OS and logged in, PostgreSQL won't require further authentication and will grant access to that user based on whatever privileges (roles) are assigned to it in the database. This is the default configuration.

Note: The location of pg_hba.conf and pg_ident.conf is OS dependent.

Not an answer, but this is a filed bug under the Chromium source: http://code.google.com/p/chromium/issues/detail?id=62363

Unfortunately, doesn't look like there's anyone working on it. :(

Sometimes you can accidentially add an import to "R", so if at the top of your code you see some weird import about that that you did not add yourself, delete the reference, and everything should go back to normal

The print statement in Python converts its arguments to strings, and outputs those strings to stdout. To save the string to a variable instead, only convert it to a string:

a = str(tag.getArtist())

The point of an interface is to specify the public API. An interface has no state. Any variables that you create are really constants (so be careful about making mutable objects in interfaces).

Basically an interface says here are all of the methods that a class that implements it must support. It probably would have been better if the creators of Java had not allowed constants in interfaces, but too late to get rid of that now (and there are some cases where constants are sensible in interfaces).

Because you are just specifying what methods have to be implemented there is no idea of state (no instance variables). If you want to require that every class has a certain variable you need to use an abstract class.

Finally, you should, generally speaking, not use public variables, so the idea of putting variables into an interface is a bad idea to begin with.

Short answer - you can't do what you want because it is "wrong" in Java.

Edit:

class Tile 
    implements Rectangle 
{
    private int height;
    private int width;

     @Override
    public int getHeight() {
        return height;
    }

    @Override
    public int getWidth() {
        return width;
    }

    @Override
    public void setHeight(int h) {
        height = h;
    }

    @Override
    public void setWidth(int w) { 
        width = w;  
    }
}

an alternative version would be:

abstract class AbstractRectangle 
    implements Rectangle 
{
    private int height;
    private int width;

     @Override
    public int getHeight() {
        return height;
    }

    @Override
    public int getWidth() {
        return width;
    }

    @Override
    public void setHeight(int h) {
        height = h;
    }

    @Override
    public void setWidth(int w) { 
        width = w;  
    }
}

class Tile 
    extends AbstractRectangle 
{
}

If you want to delete the duplicates, here's a much simpler way to do it than having to find even/odd rows into a triple sub-select:

SELECT id, name, email 
FROM users u, users u2
WHERE u.name = u2.name AND u.email = u2.email AND u.id > u2.id

And so to delete:

DELETE FROM users
WHERE id IN (
    SELECT id/*, name, email*/
    FROM users u, users u2
    WHERE u.name = u2.name AND u.email = u2.email AND u.id > u2.id
)

Much more easier to read and understand IMHO

Note: The only issue is that you have to execute the request until there is no rows deleted, since you delete only 1 of each duplicate each time

In C, to pass by reference you use the address-of operator & which should be used against a variable, but in your case, since you have used the pointer variable p, you do not need to prefix it with the address-of operator. It would have been true if you used &i as the parameter: f(&i).

You can also add this, to dereference p and see how that value matches i:

printf("p=%d \n",*p);

You can use the markup below, but note that if you set the textAllCaps to true the underline effect would be removed.

<resource>
    <string name="my_string_value">I am <u>underlined</u>.</string>
</resources>

Note

Using textAllCaps with a string (login_change_settings) that contains markup; the markup will be dropped by the caps conversion

The textAllCaps text transform will end up calling toString on the CharSequence, which has the net effect of removing any markup such as . This check looks for usages of strings containing markup that also specify textAllCaps=true.

1) When to use include directive ?

To prevent duplication of same output logic across multiple jsp's of the web app ,include mechanism is used ie.,to promote the re-usability of presentation logic include directive is used

  <%@ include file="abc.jsp" %>

when the above instruction is received by the jsp engine,it retrieves the source code of the abc.jsp and copy's the same inline in the current jsp. After copying translation is performed for the current page

Simply saying it is static instruction to jsp engine ie., whole source code of "abc.jsp" is copied into the current page

2) When to use include action ?

include tag doesn't include the source code of the included page into the current page instead the output generated at run time by the included page is included into the current page response

include tag functionality is similar to that of include mechanism of request dispatcher of servlet programming

include tag is run-time instruction to jsp engine ie., rather copying whole code into current page a method call is made to "abc.jsp" from current page

From JDK8 on words it is as simple as

final String extension = ".java";
final File currentDir = new File(YOUR_DIRECTORY_PATH);
File[] files = currentDir.listFiles((File pathname) -> pathname.getName().endsWith(extension));

One way to do it is with NumPy transpose. For a list, a:

>>> import numpy as np
>>> np.array(a).T.tolist()
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]

Or another one without zip:

>>> map(list,map(None,*a))
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]

Use strncpy

e.g.

strncpy(dest, src + beginIndex, endIndex - beginIndex);

This assumes you've

1. Validated that dest is large enough.
2. endIndex is greater than beginIndex
3. beginIndex is less than strlen(src)
4. endIndex is less than strlen(src)

var result;_x000D_
result = "1,2,3".split(","); _x000D_
console.log(result);

More info on W3Schools describing the String Split function.

Just to add, you can also retrieve a jqGrid cell value, based on the rowID plus column index (rather than the Column name):

So, to fetch the value in the forth column (column index # 3) for the row with primary key ID 1234, we could use this:

var rowID = 1234;
var columnIndex = 3;
var cellValue = $("#" + rowID).find('td').eq(columnIndex).text();

Btw, on a completely unrelated topic (but please don't vote me down):

I didn't realise that you can, fairly easily, link text boxes to your jqGrid, so your users can do instant searching, without having to open the Search dialog.

To do this, you need a bit of HTML like this:

<input type="text" name="employeeName" id="employeeName" style="width:250px" />

<!--  This will be my jqGrid control and pager -->
<table id="tblEmployees"></table>
<div id="pager"></div>

And a bit of JavaScript like this:

$("#employeeName").on('change keyup paste', function () {
    SearchByEmployeeName();
});

function SearchByEmployeeName()
{
    //  Fetch the text from our <input> control
    var searchString = $("#employeeName").val();

    //  Prepare to pass a new search filter to our jqGrid
    var f = { groupOp: "AND", rules: [] };

    //  Remember to change the following line to reflect the jqGrid column you want to search for your string in
    //  In this example, I'm searching through the UserName column.

    f.rules.push({ field: "UserName", op: "cn", data: searchString });

    var grid = $('#tblEmployees');
    grid[0].p.search = f.rules.length > 0;
    $.extend(grid[0].p.postData, { filters: JSON.stringify(f) });
    grid.trigger("reloadGrid", [{ page: 1 }]);

This is a real game-changer for me... it really makes jqGrid much more user friendly.

Users can immediately start typing in their search string, rather than needing to open the Search dialog, remember to change the operator to "contains", then start typing, and close the search dialog again.

As you're using Python 3, there is no urllib module anymore. It has been split into several modules.

This would be equivalent to urlretrieve:

import urllib.request
data = urllib.request.urlretrieve("http://...")

urlretrieve behaves exactly the same way as it did in Python 2.x, so it'll work just fine.

Basically:

• urlretrieve saves the file to a temporary file and returns a tuple (filename, headers)
• urlopen returns a Request object whose read method returns a bytestring containing the file contents

Replace

Python 2 xrange to

Python 3 range

Rest all same.

Sometimes the value needs to be trimmed of whitespace or it won't be matched, in such case this additional step can be used (source):

if(((DropDownList) myControl1).Items.Cast<ListItem>().Select(i => i.Value.Trim() == ctrl.value.Trim()).FirstOrDefault() != null){}

In Visual Studio 2008, CTRL+E+W.

From angular's documentation,

ng-init SHOULD NOT be used for any initialization. It should be used only for aliasing. https://docs.angularjs.org/api/ng/directive/ngInit

onload should be used if any expression needs to be evaluated after a partial view is loaded (by ng-include). https://docs.angularjs.org/api/ng/directive/ngInclude

The major difference between them is when used with ng-include.

<div ng-include="partialViewUrl" onload="myFunction()"></div>

In this case, myFunction is called everytime the partial view is loaded.

<div ng-include="partialViewUrl" ng-init="myFunction()"></div>

Whereas, in this case, myFunction is called only once when the parent view is loaded.

According to the documentation for 3.4, It is preferred to use attributes with attr() method.

$('<div></div>').attr(
  {
    id: 'some dynanmic|static id',
    "class": 'some dynanmic|static class'
  }
).click(function() {
  $( "span", this ).addClass( "bar" ); // example from the docs
});

In your main.ts file bootstrap after DOMContentLoaded so angular will load when DOM is fully loaded.

import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';

import { AppModule } from './app/app.module';
import { environment } from './environments/environment';

if (environment.production) {
  enableProdMode();
}



document.addEventListener('DOMContentLoaded', () => {
  platformBrowserDynamic().bootstrapModule(AppModule)
  .catch(err => console.log(err));
});

If you are using System.Net.Http.HttpClient I believe correct pattern is

var handler = new HttpClientHandler() 
{ 
    ServerCertificateCustomValidationCallback = HttpClientHandler.DangerousAcceptAnyServerCertificateValidator
};

var http = new HttpClient(handler);
var res = http.GetAsync(url);

I had same error on Ubuntu 18.04

Delete your node_modules folder and run

sudo npm install --unsafe-perm=true

I agree with somebody's recently deleted post that the differences in performance are so small that, with very very few exceptions, (he got dinged for saying never) you should not make your design decision based upon that.

In your example, where the elements are Objects, the performance difference should be minimal.

If you are dealing with a large number of primitives, an array will offer significantly better performance, both in memory and time.

Available and Condition

<target name="check-abc">
    <available file="abc.txt" property="abc.present"/>
</target>

<target name="do-if-abc" depends="check-abc" if="abc.present">
    ...
</target> 

The others are right about making the driver JAR available to your servlet container. My comment was meant to suggest that you verify from the command line whether the driver itself is intact.

Rather than an empty main(), try something like this, adapted from the included documentation:

public class LoadDriver {
    public static void main(String[] args) throws Exception {
        Class.forName("com.mysql.jdbc.Driver");
    }
}

On my platform, I'd do this:

$ ls mysql-connector-java-5.1.12-bin.jar 
mysql-connector-java-5.1.12-bin.jar
$ javac LoadDriver.java 
$ java -cp mysql-connector-java-5.1.12-bin.jar:. LoadDriver

On your platform, you need to use ; as the path separator, as discussed here and here.

One possible 'hack' would be to throttle the events using Reactive Extensions for example:

var watcher = new FileSystemWatcher("./");

Observable.FromEventPattern<FileSystemEventArgs>(watcher, "Changed")
            .Throttle(new TimeSpan(500000))
            .Subscribe(HandleChangeEvent);

watcher.EnableRaisingEvents = true;

In this case I'm throttling to 50ms, on my system that was enough, but higher values should be safer. (And like I said, it's still a 'hack').

you can append the jdbc url with

?zeroDateTimeBehavior=convertToNull&autoReconnect=true&characterEncoding=UTF-8&characterSetResults=UTF-8

With the help of this, sql convert '0000-00-00 00:00:00' as null value.

eg:

jdbc:mysql:<host-name>/<db-name>?zeroDateTimeBehavior=convertToNull&autoReconnect=true&characterEncoding=UTF-8&characterSetResults=UTF-8

If you want to do an ajax call or a simple javascript function, don't forget to close your function with the return false

like this:

function DoAction(id, name) 
{ 
    // your code
    return false;
}

If searching for an element is important, I'd recommend std::set instead of std::vector. Using this:

std::find(vec.begin(), vec.end(), x) runs in O(n) time, but std::set has its own find() member (ie. myset.find(x)) which runs in O(log n) time - that's much more efficient with large numbers of elements

std::set also guarantees all the added elements are unique, which saves you from having to do anything like if not contained then push_back()....

Copy & paste this to use git find-file SEARCHPATTERN

Printing all searched branches:

git config --global alias.find-file '!for branch in `git for-each-ref --format="%(refname)" refs/heads`; do echo "${branch}:"; git ls-tree -r --name-only $branch | nl -bn -w3 | grep "$1"; done; :'

Print only branches with results:

git config --global alias.find-file '!for branch in $(git for-each-ref --format="%(refname)" refs/heads); do if git ls-tree -r --name-only $branch | grep "$1" > /dev/null; then  echo "${branch}:"; git ls-tree -r --name-only $branch | nl -bn -w3 | grep "$1"; fi; done; :'

These commands will add some minimal shell scripts directly to your ~/.gitconfig as global git alias.

This appears to be a bug in the SelectExtensions class as it will only check the ViewData rather than the model for the selected item. So the trick is to copy the selected item from the model into the ViewData collection under the name of the property.

This is taken from the answer I gave on the MVC forums, I also have a more complete answer in a blog post that uses Kazi's DropDownList attribute...

Given a model

public class ArticleType
{
   public Guid Id { get; set; }
   public string Description { get; set; }
}

public class Article
{
    public Guid Id { get; set; }
    public string Name { get; set; }
    public ArticleType { get; set; }
}

and a basic view model of

public class ArticleModel
{
     public Guid Id { get; set; }
     public string Name { get; set; }

     [UIHint("DropDownList")]
     public Guid ArticleType { get; set; }
}

Then we write a DropDownList editor template as follows..

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %>
<script runat="server">  
    IEnumerable<SelectListItem> GetSelectList()
    {
        var metaData = ViewData.ModelMetadata;
        if (metaData == null)
        {
            return null;
        }

        var selected = Model is SelectListItem ? ((SelectListItem) Model).Value : Model.ToString();
        ViewData[metaData.PropertyName] = selected;

        var key = metaData.PropertyName + "List";
        return (IEnumerable<SelectListItem>)ViewData[key];
    }
</script>
<%= Html.DropDownList(null, GetSelectList()) %>

This will also work if you change ArticleType in the view model to a SelectListItem, though you do have to implement a type converter as per Kazi's blog and register it to force the binder to treat this as a simple type.

In your controller we then have...

public ArticleController 
{
     ...
     public ActionResult Edit(int id)
     {
          var entity = repository.FindOne<Article>(id);
          var model = builder.Convert<ArticleModel>(entity);

          var types = repository.FindAll<ArticleTypes>();
          ViewData["ArticleTypeList"] = builder.Convert<SelectListItem>(types);

          return VIew(model);
     }
     ...
}

For Android Developers,

Make sure you have enabled Facebook Login inside the Products list inside Dashboard of your Facebook project app and have added all the required details as you go through the whole flow.

The login should work without giving the same error.

You are not able to return 'multiple values' in PHP. You can return a single value, which might be an array.

function foo($test1, $test2, $test3)
{
    return array($test1, $test2, $test3);
}
$test1 = "1";
$test2 = "2";
$test3 = "3";

$arr = foo($test1, $test2, $test3);

$test1 = $arr[0];
$test2 = $arr[1];
$test3 = $arr[2];

You're better off using typed np.arrays, and then pass the data and column names as a dictionary.

import numpy as np
import pandas as pd
# Feature: np arrays are 1: efficient, 2: can be pre-sized
x = np.array(['a', 'b'], dtype=object)
y = np.array([ 1 ,  2 ], dtype=np.int32)
df = pd.DataFrame({
   'x' : x,    # Feature: column name is near data array
   'y' : y,
   }
 )

For anyone interested to implement a DropDown of custom class you can follow the bellow steps.

1. Suppose you have a class called Language with the following code and a static method which returns a List<Language>

   class Language {
     final int id;
     final String name;
     final String languageCode;
   
     const Language(this.id, this.name, this.languageCode);
   
   
   }
   
    const List<Language> getLanguages = <Language>[
           Language(1, 'English', 'en'),
           Language(2, '?????', 'fa'),
           Language(3, '????', 'ps'),
        ];
   

2. Anywhere you want to implement a DropDown you can import the Language class first use it as follow

       DropdownButton(
           underline: SizedBox(),
           icon: Icon(
                       Icons.language,
                       color: Colors.white,
                       ),
           items: getLanguages.map((Language lang) {
           return new DropdownMenuItem<String>(
                           value: lang.languageCode,
                           child: new Text(lang.name),
                         );
                       }).toList(),
   
           onChanged: (val) {
                         print(val);
                      },
         )
   

Based on something found on Code Project

Once the data table is declared based on the grid's data source, lookup the column index by column name from the columns collection. At this point, use the index as needed to obtain information from or to format the cell.

protected void gridMyGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        DataTable dt = (DataTable)((GridView)sender).DataSource;
        int colIndex = dt.Columns["MyColumnName"].Ordinal;

        e.Row.Cells[colIndex].BackColor = Color.FromName("#ffeb9c");
    }
}

XML uses a tag structures for presenting items, like <tag>item</tag>, so an XML document is a set of tags nested into each other. And JSON syntax looks like a construction from Javascript language, with all stuff like lists and dictionaries:

{
 'attrib' : 'value',
 'array' : [1, 2, 3]
}

So if you use JSON it's really simple to use a JSON strings in many script languages, especially Javascript and Python.

Not terribly elegant, but:

data.frame(rbind(as.matrix(df), as.matrix(de)))

From documentation of the rbind function:

For rbind column names are taken from the first argument with appropriate names: colnames for a matrix...

You should make sure you format the date in the correct format - RFC2822.

Since I got here with my problem I will add this answer although it is not exactly relevant to the original question. When you are implementing an interface make sure you do not forget to add the type pointer on your member function declarations. Example:

type AnimalSounder interface {
    MakeNoise()
}

type Dog struct {
    Name string
    mean bool
    BarkStrength int
}

func (dog *Dog) MakeNoise() {
    //implementation
}

I forgot the *(dog Dog) part, I do not recommend it. Then you get into ugly trouble when calling MakeNoice on an AnimalSounder interface variable of type Dog.

You could also use a URI template. If you structured your request into a restful URL Spring could parse the provided value from the url.

HTML

<li>
    <a id="byParameter" 
       class="textLink" href="<c:url value="/mapping/parameter/bar />">By path, method,and
           presence of parameter</a>
</li>

Controller

@RequestMapping(value="/mapping/parameter/{foo}", method=RequestMethod.GET)
public @ResponseBody String byParameter(@PathVariable String foo) {
    //Perform logic with foo
    return "Mapped by path + method + presence of query parameter! (MappingController)";
}

Spring URI Template Documentation

You can use getnameinfo for Windows and for Linux.

Assuming you have a good (i.e. it's members have appropriate values) sockaddr* called pSockaddr:

char clienthost[NI_MAXHOST];  //The clienthost will hold the IP address.
char clientservice[NI_MAXSERV];
int theErrorCode = getnameinfo(pSockaddr, sizeof(*pSockaddr), clienthost, sizeof(clienthost), clientservice, sizeof(clientservice), NI_NUMERICHOST|NI_NUMERICSERV);

if( theErrorCode != 0 )
{
    //There was an error.
    cout << gai_strerror(e1) << endl;
}else{
    //Print the info.
    cout << "The ip address is = " << clienthost << endl;
    cout << "The clientservice = " << clientservice << endl;
}

If you have a datetime field that gives the results like this 2018-03-30 08:43:28.177

Proposed: and you want to change the datetime to date to appear like 2018-03-30

cast(YourDateField as Date)

Referencing my comments on other answers. This is how I would work out the difference in days based on 24 hours and calender days. the days attribute works well for 24 hours and the function works best for calendar checks.

from datetime import timedelta, datetime

def cal_days_diff(a,b):

    A = a.replace(hour = 0, minute = 0, second = 0, microsecond = 0)
    B = b.replace(hour = 0, minute = 0, second = 0, microsecond = 0)
    return (A - B).days

if __name__ == '__main__':

    x = datetime(2013, 06, 18, 16, 00)
    y = datetime(2013, 06, 19, 2, 00)

    print (y - x).days          # 0
    print cal_days_diff(y, x)   # 1 

    z = datetime(2013, 06, 20, 2, 00)

    print (z - x).days          # 1
    print cal_days_diff(z, x)   # 2 

Adding the below code helped me overcome the issue.

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls11;

Remember that when you write:

MyArray = Range("A1:A5000")

you are really writing

MyArray = Range("A1:A5000").Value

You can also use names:

MyArray = Names("MyWSTable").RefersToRange.Value

But Value is not the only property of Range. I have used:

MyArray = Range("A1:A5000").NumberFormat

I doubt

MyArray = Range("A1:A5000").Font

would work but I would expect

MyArray = Range("A1:A5000").Font.Bold

to work.

I do not know what formats you want to copy so you will have to try.

However, I must add that when you copy and paste a large range, it is not as much slower than doing it via an array as we all thought.

Post Edit information

Having posted the above I tried by own advice. My experiments with copying Font.Color and Font.Bold to an array have failed.

Of the following statements, the second would fail with a type mismatch:

  ValueArray = .Range("A1:T5000").Value
  ColourArray = .Range("A1:T5000").Font.Color

ValueArray must be of type variant. I tried both variant and long for ColourArray without success.

I filled ColourArray with values and tried the following statement:

  .Range("A1:T5000").Font.Color = ColourArray

The entire range would be coloured according to the first element of ColourArray and then Excel looped consuming about 45% of the processor time until I terminated it with the Task Manager.

There is a time penalty associated with switching between worksheets but recent questions about macro duration have caused everyone to review our belief that working via arrays was substantially quicker.

I constructed an experiment that broadly reflects your requirement. I filled worksheet Time1 with 5000 rows of 20 cells which were selectively formatted as: bold, italic, underline, subscript, bordered, red, green, blue, brown, yellow and gray-80%.

With version 1, I copied every 7th cells from worksheet "Time1" to worksheet "Time2" using copy.

With version 2, I copied every 7th cells from worksheet "Time1" to worksheet "Time2" by copying the value and the colour via an array.

With version 3, I copied every 7th cells from worksheet "Time1" to worksheet "Time2" by copying the formula and the colour via an array.

Version 1 took an average of 12.43 seconds, version 2 took an average of 1.47 seconds while version 3 took an average of 1.83 seconds. Version 1 copied formulae and all formatting, version 2 copied values and colour while version 3 copied formulae and colour. With versions 1 and 2 you could add bold and italic, say, and still have some time in hand. However, I am not sure it would be worth the bother given that copying 21,300 values only takes 12 seconds.

** Code for Version 1**

Some people, like me, will benefit from using the :focus-within pseudo-class.

Using it will apply the css you want to a div, for instance.

You can read more here https://developer.mozilla.org/en-US/docs/Web/CSS/:focus-within

Seems that only index.js get loaded when you require("./routes") . I used the following code in index.js to load the rest of the routes:

var fs = require('fs')
  , path = require('path');

fs.readdirSync(__dirname).forEach(function(file){
  var route_fname = __dirname + '/' + file;
  var route_name = path.basename(route_fname, '.js');
  if(route_name !== 'index' && route_name[0] !== "."){ 
    exports[route_name] = require(route_fname)[route_name];
  }
});

Let us say you have a data frame you created and named "Data_output", you can simply export it to same directory by using the following syntax.

write.csv(Data_output, "output.csv", row.names = F, quote = F)

you can insert using loop if you want to insert some random values.

BEGIN 
    FOR x IN 1 .. 1000 LOOP
         INSERT INTO MULTI_INSERT_DEMO (ID, NAME)
         SELECT x, 'anyName' FROM dual;
    END LOOP;
END;

I had also similar problem. In my case brokerUrl was not configured properly. So that's way I received following Error:

Cause: Error While attempting to add new Connection to the pool: nested exception is javax.jms.JMSException: Could not connect to broker URL : tcp://localhost:61616. Reason: java.net.ConnectException: Connection refused

& I resolved it following way.

   ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory();

  connectionFactory.setBrokerURL("tcp://hostname:61616");
  connectionFactory.setUserName("admin");
  connectionFactory.setPassword("admin");

If you want to do this without using a second table, you can do a LIKE comparison with a CAST:

DECLARE @myList varchar(15)
SET @myList = ',1,2,3,4,'

SELECT *
FROM myTable
WHERE @myList LIKE '%,' + CAST(myColumn AS varchar(15)) + ',%'

If the field you're comparing is already a string then you won't need to CAST.

Surrounding both the column match and each unique value in commas will ensure an exact match. Otherwise, a value of 1 would be found in a list containing ',4,2,15,'

I had the same issue on 14.04 with docker 1.9.1.

The upstart service command did work when I used sudo, even though I was root:

$ whoami
root
$ service docker status
status: Unbekannter Auftrag: docker

$ sudo service docker status
docker start/running, process 7394

It seems to depend on the environment variables.

service docker status works when becoming root with su -, but not when only using su:

$ su
Password:
$ service docker status
status: unknown job: docker
$ exit
$ su -
Password:

One thing one needs to keep in mind about the storage is the as-if rule. The compiler is not required to put a variable in a specific place - instead it can place it wherever it pleases for as long as the compiled program behaves as if it were run in the abstract C machine according to the rules of the abstract C machine. This applies to all storage durations. For example:

• a variable that is not accessed all can be eliminated completely - it has no storage... anywhere. Example - see how there is 42 in the generated assembly code but no sign of 404.
• a variable with automatic storage duration that does not have its address taken need not be stored in memory at all. An example would be a loop variable.
• a variable that is const or effectively const need not be in memory. Example - the compiler can prove that foo is effectively const and inlines its use into the code. bar has external linkage and the compiler cannot prove that it would not be changed outside the current module, hence it is not inlined.
• an object allocated with malloc need not reside in memory allocated from heap! Example - notice how the code does not have a call to malloc and neither is the value 42 ever stored in memory, it is kept in a register!
• thus an object that has been allocated by malloc and the reference is lost without deallocating the object with free need not leak memory...
• the object allocated by malloc need not be within the heap below the program break (sbrk(0)) on Unixen...

Updated.. I solved this issue by stating the charset on PDO connection as below:

"mysql:host=$host;dbname=$db;charset=utf8"

All data received was then in the correct charset for the rest of the code to use

In case you want to pass in a block, say, for a glyphicon button, as in the following:

<%= link_to my_url, class: "stuff" do %>
  <i class="glyphicon glyphicon-inbox></i> Nice glyph-button
<% end %>

Then passing querystrings params could be accomplished through:

<%= link_to url_for(params.merge(my_params: "value")), class: "stuff" do %>
  <i class="glyphicon glyphicon-inbox></i> Nice glyph-button
<% end %>

If you try set a value in datetime-local

date("Y-m-d\TH:i",strtotime('2010-12-30 23:21:46'));

//output : 2010-12-30T23:21

Also you can use faster_than_requests package. That's very fast and simple:

import faster_than_requests as r
content = r.get2str("http://test.com/")

Look at this comparison:

Only this worked for me:

searchKeyword.replace(/'/g, "\\\'");//searchKeyword contains "d'av"

So, the result variable will contain "d\'av".

I don't know why with the RegEx didn't work, maybe because of the JS framework that I'm using (Backbone.js)

I had the same issue, the problem was in the @ContextConfiguration in me test classes, i was loading the servlet context too i just change:

@ContextConfiguration(locations = { "classpath*:**\*-context.xml", "classpath*:**\*-config.xml" })

to:

@ContextConfiguration(locations = { "classpath:**\*-context.xml", "classpath:**\*-config.xml" })

and that´s it. this way im only loading all the files with the pattern *-context.xml in me test path.

I made a small treatment after the URI object creation

 if (url.startsWith("http:/")) {
        if (!url.contains("http://")) {
            url = url.replaceAll("http:/", "http://");
        }
    } else {
        url = "http://" + url;
    }
    URI uri = new URI(url);
    String domain = uri.getHost();
    return domain.startsWith("www.") ? domain.substring(4) : domain;

My try :

public static byte[] toBytes(final int intVal, final int... intArray) {
    if (intArray == null || (intArray.length == 0)) {
        return ByteBuffer.allocate(4).putInt(intVal).array();
    } else {
        final ByteBuffer bb = ByteBuffer.allocate(4 + (intArray.length * 4)).putInt(intVal);
        for (final int val : intArray) {
            bb.putInt(val);
        }
        return bb.array();
    }
}

With it you can do this :

byte[] fourBytes = toBytes(0x01020304);
byte[] eightBytes = toBytes(0x01020304, 0x05060708);

Full class is here : https://gist.github.com/superbob/6548493, it supports initialization from shorts or long

byte[] eightBytesAgain = toBytes(0x0102030405060708L);

Your document should not contain two divs with the same id. This is invalid HTML, and as a result, the underlying DOM API does not support it.

From the HTML standard:

id = name [CS] This attribute assigns a name to an element. This name must be unique in a document.

You can either assign different ids to each div and select them both using $('#id1, #id2). Or assign the same class to both elements (.cls for example), and use $('.cls') to select them both.

The answer is depends how you are using the objects of javascript. As already pointed loading the javascript files at footer rather than header certainly improves the performance but care should be taken that the objects which are used are initialized later than they are loaded at footer. One more way is load the 'js' files placed in folder which will be available to all the files.

The information schema isn't the place to treat these things (see DDL database commands).

When you add a comment you need to change the table structure (table comments).

From MySQL 5.6 documentation:

INFORMATION_SCHEMA is a database within each MySQL instance, the place that stores information about all the other databases that the MySQL server maintains. The INFORMATION_SCHEMA database contains several read-only tables. They are actually views, not base tables, so there are no files associated with them, and you cannot set triggers on them. Also, there is no database directory with that name.

Although you can select INFORMATION_SCHEMA as the default database with a USE statement, you can only read the contents of tables, not perform INSERT, UPDATE, or DELETE operations on them.

Chapter 21 INFORMATION_SCHEMA Tables

$date = 'Dec 25 2099';
echo date('d/m/Y', strtotime($date));

This returns 01/01/1970, that means php doesn't support all dates, it returns correct formatted date till Jan 19 2038 but Jan 20 2038 returns 01/01/1970

Just remove the fade class and if you want more animations to be perform on the Modal just use animate.css classes in your Modal.

This should work:

$(".hit").click(function(){    
   var value=$(this).closest('tr').children('td:first').text();
   alert(value);    
});

Explanation:

• .closest('tr') gets the nearest ancestor that is a <tr> element (so in this case the row where the <a> element is in).
• .children('td:first') gets all the children of this element, but with the :first selector we reduce it to the first <td> element.
• .text() gets the text inside the element

As you can see from the other answers, there is more than only one way to do this.

This issue has been fixed in m2e 1.5.0 which is available for Eclipse Kepler (4.3) and Luna (4.4)

Please see https://bugs.eclipse.org/bugs/show_bug.cgi?id=374332#c14

The problem is caused by the fact that STS (the Spring IDE/Eclipse), as well Eclipse and other Eclipse based IDE's, use the m2e(clipse) plugin but that eclipse:eclipse has been probably been run on the project. When m2e encounters a "var" .classpath entry, it throws this error.

The update sites are specified at the following url:
http://eclipse.org/m2e/m2e-downloads.html

If you can't use m2e 1.5.0 for any reason, then :

1. Disable the maven nature for the project (via the right-click menu)

2. Run mvn eclipse:clean (while your project is open in STS/eclipse). Depending on the timing, you might need to do a refresh or two on the project before re-enabling the maven nature. You should be able to see that your project has lost it's Maven nature. (The eclipse:clean goal just deletes the .project, .classpath and .settings/ files/directories. You can also just remove those files (again while the project is open) instead of running mvn eclipse:clean.)

3. Re-enable the maven nature.
   (Most of the time, this can be done by right-clicking on the project in question in the package explorer pane, and then choosing 'Configure'-> 'Convert to Maven Project')

select t1.rowInt,t1.Value,t2.Value-t1.Value as diff
from (select * from myTable) as t1,
     (select * from myTable where rowInt!=1
      union all select top 1 rowInt=COUNT(*)+1,Value=0 from myTable) as t2
where t1.rowInt=t2.rowInt-1

There is actually no difference as both require 1 click:

• Eclipse: manual Save, auto-compile.
• IntelliJ: auto Save, manual compile.

Simplest solution is just to get used to it. Because when you spend most of your daytime in your IDE, then better have fast habits in one than slow habits in several of them.

Oh, there are tons of example. Just have a look at anything within glib or gtk. You can see the work of function pointers in work there all the way.

Here e.g the initialization of the gtk_button stuff.

static void
gtk_button_class_init (GtkButtonClass *klass)
{
  GObjectClass *gobject_class;
  GtkObjectClass *object_class;
  GtkWidgetClass *widget_class;
  GtkContainerClass *container_class;

  gobject_class = G_OBJECT_CLASS (klass);
  object_class = (GtkObjectClass*) klass;
  widget_class = (GtkWidgetClass*) klass;
  container_class = (GtkContainerClass*) klass;

  gobject_class->constructor = gtk_button_constructor;
  gobject_class->set_property = gtk_button_set_property;
  gobject_class->get_property = gtk_button_get_property;

And in gtkobject.h you find the following declarations:

struct _GtkObjectClass
{
  GInitiallyUnownedClass parent_class;

  /* Non overridable class methods to set and get per class arguments */
  void (*set_arg) (GtkObject *object,
           GtkArg    *arg,
           guint      arg_id);
  void (*get_arg) (GtkObject *object,
           GtkArg    *arg,
           guint      arg_id);

  /* Default signal handler for the ::destroy signal, which is
   *  invoked to request that references to the widget be dropped.
   *  If an object class overrides destroy() in order to perform class
   *  specific destruction then it must still invoke its superclass'
   *  implementation of the method after it is finished with its
   *  own cleanup. (See gtk_widget_real_destroy() for an example of
   *  how to do this).
   */
  void (*destroy)  (GtkObject *object);
};

The (*set_arg) stuff is a pointer to function and this can e.g be assigned another implementation in some derived class.

Often you see something like this

struct function_table {
   char *name;
   void (*some_fun)(int arg1, double arg2);
};

void function1(int  arg1, double arg2)....


struct function_table my_table [] = {
    {"function1", function1},
...

So you can reach into the table by name and call the "associated" function.

Or maybe you use a hash table in which you put the function and call it "by name".

Using AndroidManifest.xml

<activity android:name=".YourActivityName"
      android:windowSoftInputMode="stateHidden"  
 />

Using Java

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);

using the above solution keyboard hide but edittext from taking focus when activiy is created, but grab it when you touch them using:

add in your EditText

<EditText
android:focusable="false" />

also add listener of your EditText

youredittext.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
    v.setFocusable(true);
    v.setFocusableInTouchMode(true);
    return false;
}});

You can use sneaky-save gem: https://rubygems.org/gems/sneaky-save.

Note this cannot help in saving associations along without validations. It throws error 'created_at cannot be null' as it directly inserts the sql query unlike a model. To implement this, we need to update all auto generated columns of db.

I have written a small routine which copies formula from a cell to clipboard which one can easily paste in Visual Basic Editor.

    Public Sub CopyExcelFormulaInVBAFormat()
        Dim strFormula As String
        Dim objDataObj As Object

        '\Check that single cell is selected!
       If Selection.Cells.Count > 1 Then
            MsgBox "Select single cell only!", vbCritical
            Exit Sub
        End If

        'Check if we are not on a blank cell!
       If Len(ActiveCell.Formula) = 0 Then
            MsgBox "No Formula To Copy!", vbCritical
            Exit Sub
        End If

        'Add quotes as required in VBE
       strFormula = Chr(34) & Replace(ActiveCell.Formula, Chr(34), Chr(34) & Chr(34)) & Chr(34)

        'This is ClsID of MSFORMS Data Object
       Set objDataObj = CreateObject("New:{1C3B4210-F441-11CE-B9EA-00AA006B1A69}")
        objDataObj.SetText strFormula, 1
        objDataObj.PutInClipboard
        MsgBox "VBA Format formula copied to Clipboard!", vbInformation

        Set objDataObj = Nothing

    End Sub

This is the natural javascript option

var myArray = ['1','2',3,4]_x000D_
_x000D_
myArray.forEach(function(value){_x000D_
  console.log(value);_x000D_
});

However it won't work if you're using await inside the forEach loop because forEach is not asynchronous. you'll be forced to use the second answer or some other equivalent:

let myArray = ["a","b","c","d"];_x000D_
for (let item of myArray) {_x000D_
  console.log(item);_x000D_
}

Or you could create an asyncForEach explained here:

https://codeburst.io/javascript-async-await-with-foreach-b6ba62bbf404

Brian Neal's suggestion of running management commands via cron works well, but if you're looking for something a little more robust (yet not as elaborate as Celery) I'd look into a library like Kronos:

# app/cron.py

import kronos

@kronos.register('0 * * * *')
def task():
    pass

You can do it programmatically:

ddlColor.DataSource = from p in db.ProductTypes
                                  where p.ProductID == pID
                                  orderby p.Color 
                                  select new { p.Color };
ddlColor.DataTextField = "Color";
ddlColor.DataBind();
ddlColor.Items.Insert(0, new ListItem("Select", "NA"));

Or add it in markup as:

<asp:DropDownList .. AppendDataBoundItems="true">
   <Items>
       <asp:ListItem Text="Select" Value="" />
   </Items>
</asp:DropDownList>

If you just want to change the legend title, you can do the following:

import seaborn as sns
import matplotlib.pyplot as plt
tips = sns.load_dataset("tips")

g = sns.lmplot(
    x="total_bill", 
    y="tip", 
    hue="smoker", 
    data=tips,  
    legend=True
)

g._legend.set_title("New Title")

I would recommend EditArea for live editing of a syntax hightlighted textarea.

Another way: you can use RedisWorks library.

pip install redisworks

>>> from redisworks import Root
>>> root = Root()
>>> root.something = {1:"a", "b": {2: 2}}  # saves it as Hash type in Redis
...
>>> print(root.something)  # loads it from Redis
{'b': {2: 2}, 1: 'a'}
>>> root.something['b'][2]
2

It converts python types to Redis types and vice-versa.

>>> root.sides = [10, [1, 2]]  # saves it as list in Redis.
>>> print(root.sides)  # loads it from Redis
[10, [1, 2]]
>>> type(root.sides[1])
<class 'list'>

Disclaimer: I wrote the library. Here is the code: https://github.com/seperman/redisworks

You may use Map.entrySet() method:

for (Map.Entry entry : objectSet.entrySet())
{
    System.out.println("key: " + entry.getKey() + "; value: " + entry.getValue());
}

The official naming conventions aren't that strict, they don't even 'forbid' camel case notation except for prefix (com in your example).

But I personally would avoid upper case letters and hyphenations, even numbers. I'd choose com.stackoverflow.mypackage like Bragboy suggested too.

(hyphenations '-' are not legal in package names)

EDIT

Interesting - the language specification has something to say about naming conventions too.

In Chapter 7.7 Unique Package Names we see examples with package names that consist of upper case letters (so CamelCase notation would be OK) and they suggest to replace hyphonation by an underscore ("mary-lou" -> "mary_lou") and prefix java keywords with an underscore ("com.example.enum" -> "com.example._enum")

Some more examples for upper case letters in package names can be found in chapter 6.8.1 Package Names.

You should use the python-daemon library, it takes care of everything.

From PyPI: Library to implement a well-behaved Unix daemon process.

Use explicit injection. No other approach will allow you for instance to run tests in parallel in the same JVM.

Patterns that use anything classloader wide like static log binder or messing with environmental thinks like logback.XML are bust when it comes to testing.

Consider the parallelized tests I mention , or consider the case where you want to intercept logging of component A whose construction is hidden behind api B. This latter case is easy to deal with if you are using a dependency injected loggerfactory from the top, but not if you inject Logger as there no seam in this assembly at ILoggerFactory.getLogger.

And its not all about unit testing either. Sometimes we want integration tests to emit logging. Sometimes we don't. Someone's we want some of the integration testing logging to be selectively suppressed, eg for expected errors that would otherwise clutter the CI console and confuse. All easy if you inject ILoggerFactory from the top of your mainline (or whatever di framework you might use)

So...

Either inject a reporter as suggested or adopt a pattern of injecting the ILoggerFactory. By explicit ILoggerFactory injection rather than Logger you can support many access/intercept patterns and parallelization.

Open the XAMMP php.ini file (the default path is C:\xammp\php\php.ini) and change the code (;extension=ldap) to extension=php_ldap.dll and save. Restart XAMMP and save.

Are you sure that you want "055" as opposed to "55"? Some programs interpret a leading zero as meaning octal, so that it would read 055 as (decimal) 45 instead of (decimal) 55.

That should just mean dropping the '0' (zero-fill) flag.

e.g., change System.out.printf("%03d ", x); to the simpler System.out.printf("%3d ", x);

If you are writing in C++ you are probably writing for performance. Using new and the free store is much slower than using the stack (especially when using threads) so only use it when you need it.

As others have said, you need new when your object needs to live outside the function or object scope, the object is really large or when you don't know the size of an array at compile time.

Also, try to avoid ever using delete. Wrap your new into a smart pointer instead. Let the smart pointer call delete for you.

There are some cases where a smart pointer isn't smart. Never store std::auto_ptr<> inside a STL container. It will delete the pointer too soon because of copy operations inside the container. Another case is when you have a really large STL container of pointers to objects. boost::shared_ptr<> will have a ton of speed overhead as it bumps the reference counts up and down. The better way to go in that case is to put the STL container into another object and give that object a destructor that will call delete on every pointer in the container.

if you're uncomfortable with returning addresses and have just a single variable eg. an integer value to return, you can even typecast it into (void *) before passing it, and then when you collect it in the main, again typecast it into (int). You have the value without throwing up ugly warnings.

I found that using the XFBML version of the Facebook like button instead of the HTML5 version fixed this problem. Add the below code where you want the button to appear:

<div id="fb-root"></div>
<script>(function (d, s, id) {
    var js, fjs = d.getElementsByTagName(s)[0];
    if (d.getElementById(id)) return;
    js = d.createElement(s); js.id = id;
    js.src = "//connect.facebook.net/en_GB/all.js#xfbml=1";
    fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>

<fb:like send="true" layout="button_count" width="50" show_faces="false" font="arial"></fb:like>

Then add this to your HTML tag:

 xmlns:fb="http://ogp.me/ns/fb#"

Scato wrotes:

anything you want to use for bitwise operations must be between 0x80000000 (-2147483648 or -2^31) and 0x7fffffff (2147483647 or 2^31 - 1).

the console will tell you that 0x80000000 equals +2147483648, but 0x80000000 & 0x80000000 equals -2147483648

Hex-Decimals are unsigned positive values, so 0x80000000 = 2147483648 - thats mathematically correct. If you want to make it a signed value you have to right shift: 0x80000000 >> 0 = -2147483648. You can write 1 << 31 instead, too.

An example, available for POSIX compliant systems :

/*
 * This program displays the names of all files in the current directory.
 */

#include <dirent.h> 
#include <stdio.h> 

int main(void) {
  DIR *d;
  struct dirent *dir;
  d = opendir(".");
  if (d) {
    while ((dir = readdir(d)) != NULL) {
      printf("%s\n", dir->d_name);
    }
    closedir(d);
  }
  return(0);
}

Beware that such an operation is platform dependant in C.

Source : http://faq.cprogramming.com/cgi-bin/smartfaq.cgi?answer=1046380353&id=1044780608

I built a pretty simple format function that I call whenever I need a simple date formatted. It deals with formatting single digits to double digits when they're less than 10. It kicks out a date formatted as Sat Sep 29 2018 - 00:05:44

This function is used as part of a utils variable so it's called as:

let timestamp = utils._dateFormatter('your date string');

var utils = {
  _dateFormatter: function(dateString) {
    let d = new Date(dateString);
    let hours = d.getHours();
    let minutes = d.getMinutes();
    let seconds = d.getSeconds();
    d = d.toDateString();
    if (hours < 10) {
      hours = '0' + hours;
    }
    if (minutes < 10) {
      minutes = '0' + minutes;
    }
    if (seconds < 10) {
      seconds = '0' + seconds;
    }
    let formattedDate = d + ' - ' + hours + ':' + minutes + ':' + seconds;
    return formattedDate;
  }
}

Assuming you already have a application created under google developer console, Follow the below steps

1. Go to the following link https://console.cloud.google.com/apis/dashboard? you will be getting the below page

3. Select the desired option - in this case "Maps JavaScript API"
4. Click ENABLE button as below,

On my system (Ubuntu 17.10) your example just works as desired, both when typed from the command line (into sh) and when executed as a sh script:

[bash]§ sh
$ STR="Hello\nWorld"
$ echo $STR
Hello
World
$ exit
[bash]§ echo "STR=\"Hello\nWorld\"
> echo \$STR" > test-str.sh
[bash]§ cat test-str.sh 
STR="Hello\nWorld"
echo $STR
[bash]§ sh test-str.sh 
Hello
World

I guess this answers your question: it just works. (I have not tried to figure out details such as at what moment exactly the substitution of the newline character for \n happens in sh).

However, i noticed that this same script would behave differently when executed with bash and would print out Hello\nWorld instead:

[bash]§ bash test-str.sh
Hello\nWorld

I've managed to get the desired output with bash as follows:

[bash]§ STR="Hello
> World"
[bash]§ echo "$STR"

Note the double quotes around $STR. This behaves identically if saved and run as a bash script.

The following also gives the desired output:

[bash]§ echo "Hello
> World"

Usually, if the command is an external program, you can use the OS to help you here.

command > file_output.txt

So your C code would be doing something like

exec("command > file_output.txt");

Then you can use the file_output.txt file.

display: inline-block is your friend you just need all three parts of the construct - before, the "block", after - to be one, then you can vertically align them all to the middle:

Working Example

(it looks like your picture anyway ;))

CSS:

p, div {
  display: inline-block; 
  vertical-align: middle;
}
p, div {
  display: inline !ie7; /* hack for IE7 and below */
}

table {
  background: #000; 
  color: #fff; 
  font-size: 16px; 
  font-weight: bold; margin: 0 10px;
}

td {
  padding: 5px; 
  text-align: center;
}

HTML:

<p>some text</p> 
<div>
  <table summary="">
  <tr><td>A</td></tr>
  <tr><td>B</td></tr>
  <tr><td>C</td></tr>
  <tr><td>D</td></tr>
  </table>
</div> 
<p>continues afterwards</p>

The fix was at the accepted answer. Yet if someone wants to know why it worked and why the implementation in the SO question didn't work,

First, functions are first class objects in JavaScript. That means they are treated like any other variable. Function can be passed as an argument to other functions, can be returned by another function and can be assigned as a value to a variable. Read more here.

So we use that variable to invoke the function by adding parentheses () at the end.

One thing, If you have a function that returns a funtion and you just need to call that returned function, you can just have double paranthesis when you call the outer function ()().

Surprisingly, many of the answers don't give complete working code. Here it is:

public static void createFile(String fullPath) throws IOException {
    File file = new File(fullPath);
    file.getParentFile().mkdirs();
    file.createNewFile();
}

public static void main(String [] args) throws Exception {
    String path = "C:/donkey/bray.txt";

Along with the gnobal's above solution, I had to set alpha to 0 in the layout file of that particular activity, because on certain phone (Redmi Narzo 20 pro running on Android 10) a dialog portion of the screen was showing with the screen that was supposed to be transparent. For some reason the windowIsFloating was causing this issue, but on removing it I wasn't getting the desired output.

Steps:

1. Add the following in the style.xml located under res > values > styles.xml

    <style name="Theme.Transparent" parent="android:Theme">
      <item name="android:windowIsTranslucent">true</item>
      <item name="android:windowBackground">@android:color/transparent</item>
      <item name="android:windowContentOverlay">@null</item>
      <item name="android:windowNoTitle">true</item>
      <item name="android:windowIsFloating">true</item>
      <item name="android:backgroundDimEnabled">false</item>
      <item name="android:colorBackgroundCacheHint">@null</item>
    </style>
   

   
   

2. Set the theme of the activity with the above style in AndroidManifest.xml

   <activity
         android:name=".activityName"
         android:theme="@style/Theme.Transparent"/>
   

   
   

3. Open your layout file of the activity on which you applied the above style and set it's alpha value to 0 (android:alpha="0") for the parent layout element.

   <?xml version="1.0" encoding="utf-8"?>
   <androidx.constraintlayout.widget.ConstraintLayout 
       xmlns:android="http://schemas.android.com/apk/res/android"
       xmlns:tools="http://schemas.android.com/tools"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:alpha="0">
   
     <WebView        
           android:layout_width="match_parent"
           android:layout_height="match_parent"
           android:alpha="0"/>
   
   </androidx.constraintlayout.widget.ConstraintLayout>
   

The best solution in C#/all static .NET languages is to use the CodeDOM for such things. (As a note, its other main purpose is for dynamically constructing bits of code, or even whole classes.)

Here's a nice short example take from LukeH's blog, which uses some LINQ too just for fun.

using System;
using System.Collections.Generic;
using System.Linq;
using Microsoft.CSharp;
using System.CodeDom.Compiler;

class Program
{
    static void Main(string[] args)
    {
        var csc = new CSharpCodeProvider(new Dictionary<string, string>() { { "CompilerVersion", "v3.5" } });
        var parameters = new CompilerParameters(new[] { "mscorlib.dll", "System.Core.dll" }, "foo.exe", true);
        parameters.GenerateExecutable = true;
        CompilerResults results = csc.CompileAssemblyFromSource(parameters,
        @"using System.Linq;
            class Program {
              public static void Main(string[] args) {
                var q = from i in Enumerable.Range(1,100)
                          where i % 2 == 0
                          select i;
              }
            }");
        results.Errors.Cast<CompilerError>().ToList().ForEach(error => Console.WriteLine(error.ErrorText));
    }
}

The class of primary importance here is the CSharpCodeProvider which utilises the compiler to compile code on the fly. If you want to then run the code, you just need to use a bit of reflection to dynamically load the assembly and execute it.

Here is another example in C# that (although slightly less concise) additionally shows you precisely how to run the runtime-compiled code using the System.Reflection namespace.

Try iterator function

For example you can return first element

x = [['a',1],['b',2],['a',1]]

_.uniq(x,false,function(i){  

   return i[0]   //'a','b'

})

=> [['a',1],['b',2]]

Try doing this in a shell:

var="  3918912k"
echo ${var//[[:blank:]]/}

That uses parameter expansion (it's a non posix feature)

[[:blank:]] is a POSIX regex class (remove spaces, tabs...), see http://www.regular-expressions.info/posixbrackets.html

It's an unportable way to remove all data from the input buffer till the next newline. I've seen it used in cases like that:

char c;
char s[32];
puts("Type a char");
c=getchar();
fflush(stdin);
puts("Type a string");
fgets(s,32,stdin);

Without the fflush(), if you type a character, say "a", and the hit enter, the input buffer contains "a\n", the getchar() peeks the "a", but the "\n" remains in the buffer, so the next fgets() will find it and return an empty string without even waiting for user input.

However, note that this use of fflush() is unportable. I've tested right now on a Linux machine, and it does not work, for example.

IF this is only occurring on deployments, be sure that you have the dependency of the package you are referencing in the .war. For instance, this was working locally on my machine, with debug configurations working fine, but after deploying to Amazon's Elastic Beanstalk , I received this error and noticed one of the dependencies was not bundled in the .war package.

The ConcurentLinkedQueue is a very efficient wait/lock free implementation (see the javadoc for reference), so not only you don't need to synchronize, but the queue will not lock anything, thus being virtually as fast as a non synchronized (not thread safe) one.

You should make tags their own table with a linking table.

items:
id    object
1     lamp  
2     table   
3     stool  
4     bench 

tags:
id     tag
1      furniture
2      chair

items_tags:
item_id tag_id
1       1
2       1
3       1
4       1
3       2
4       2

Just in case it helps; I do this to get the Bitmap:

InputStream is = context.getContentResolver().openInputStream(imageUri);
Bitmap bitmap = BitmapFactory.decodeStream(is);

Tagging on to mecca831's answer:

ssh -v -i generated-key.pem [email protected]

[[email protected] ~]$ sudo passwd ec2-user newpassword newpassword

[[email protected] ~]$ sudo vi /etc/ssh/sshd_config Modify the file as follows:

    # To disable tunneled clear text passwords, change to no here!
    PasswordAuthentication yes
    #PermitEmptyPasswords no
    # EC2 uses keys for remote access
    #PasswordAuthentication no

Save

[[email protected] ~]$ sudo service sshd stop [[email protected] ~]$ sudo service sshd start

you should be able to exit and ssh in as follows:

ssh [email protected]

and be prompted for password no longer needing the key.

As JavaScript is client side and JSP is Server side.

So Javascript does not execute until it gets to the browser, But Java executes on the server. So, Java does not know the value of the JavaScript variable.

However you assign value of Java variable to JavaScript variable.

Here's how to handle it with a random option element defined as the default value (in this case Text 2 is the default):

<select id="name2" >
   <option value="">select all</option>
   <option value="1">Text 1</option>
   <option value="2" selected="selected">Text 2</option>
   <option value="3">Text 3</option>
</select>
<script>
    $('#name2 option[selected]').prop('selected', true);
</script>

The most simple way:

>>> import re
>>> string = 'This is a string, with words!'
>>> re.findall(r'\w+', string)
['This', 'is', 'a', 'string', 'with', 'words']

You can fill a hidden field from your JavaScript code and do an explicit postback from JavaScript. Then from the server side, check that hiddenfield and do whatever necessary.

Try this:

$("input[type=checkbox]").prop('checked', true).uniform();

i dont know how to diable home button. as long as my knowledge i got folowing link.

refer the link:- http://developer.android.com/reference/android/view/KeyEvent.html#KEYCODE_HOME

Key code constant: Home key. This key is handled by the framework and is never delivered to applications.

But,we can diable back button. hope following code helps you out.

@Override
public void onBackPressed() {
    //return nothing 
    return;
}

The easy-to-remember, lazy and perhaps imperfect solution:

Directory.GetFiles(dir, "*.dll").Union(Directory.GetFiles(dir, "*.exe"))

You could also do it with a Func like this

@{
    var getStyle = new Func<int, int, string>((width, margin) => string.Format("width: {0}px; margin: {1}px;", width, margin));
}

<div style="@getStyle(50, 2)"></div>

Why you don't use a DELETE CASCADE FK ?

There is another library with much cleaner API and type-safe data. https://github.com/kodart/Httpzoid

Here is a simple usage example

Http http = HttpFactory.create(context);
http.post("http://example.com/users")
    .data(new User("John"))
    .execute();

Or more complex with callbacks

Http http = HttpFactory.create(context);
http.post("http://example.com/users")
    .data(new User("John"))
    .handler(new ResponseHandler<Void>() {
        @Override
        public void success(Void ignore, HttpResponse response) {
        }

        @Override
        public void error(String message, HttpResponse response) {
        }

        @Override
        public void failure(NetworkError error) {
        }

        @Override
        public void complete() {
        }
    }).execute();

It is fresh new, but looks very promising.

Starting with v0.20.0, the dtype keyword argument in read_excel() function could be used to specify the data types that needs to be applied to the columns just like it exists for read_csv() case.

Using converters and dtype arguments together on the same column name would lead to the latter getting shadowed and the former gaining preferance.

1) Inorder for it to not interpret the dtypes but rather pass all the contents of it's columns as they were originally in the file before, we could set this arg to str or object so that we don't mess up our data. (one such case would be leading zeros in numbers which would be lost otherwise)

pd.read_excel('file_name.xlsx', dtype=str)            # (or) dtype=object

2) It even supports a dict mapping wherein the keys constitute the column names and values it's respective data type to be set especially when you want to alter the dtype for a subset of all the columns.

# Assuming data types for `a` and `b` columns to be altered
pd.read_excel('file_name.xlsx', dtype={'a': np.float64, 'b': np.int32})

Since Spring 3.1 the id attribute is an xsd:string and permits the same range of characters as the name attribute.

The only difference between an id and a name is that a name can contain multiple aliases separated by a comma, semicolon or whitespace, whereas an id must be a single value.

From the Spring 3.2 documentation:

In XML-based configuration metadata, you use the id and/or name attributes to specify the bean identifier(s). The id attribute allows you to specify exactly one id. Conventionally these names are alphanumeric ('myBean', 'fooService', etc), but may special characters as well. If you want to introduce other aliases to the bean, you can also specify them in the name attribute, separated by a comma (,), semicolon (;), or white space. As a historical note, in versions prior to Spring 3.1, the id attribute was typed as an xsd:ID, which constrained possible characters. As of 3.1, it is now xsd:string. Note that bean id uniqueness is still enforced by the container, though no longer by XML parsers.

In addition to the answers above:

If you created/edited your .sh script file in Windows, make sure it was saved with line ending in Unix format. By default many editors in Windows will convert Unix line endings to Windows format and Linux will not recognize shebang (#!/bin/sh) at the beginning of the file. So Linux will produce the error message like if there is no shebang.

Tips:

• If you use Notepad++, you need to click "Edit/EOL Conversion/UNIX (LF)"
• If you use Visual Studio, I would suggest installing "End Of Line" plugin. Then you can make line endings visible by pressing Ctrl-R, Ctrl-W. And to set Linux style endings you can press Ctrl-R, Ctrl-L. For Windows style, press Ctrl-R, Ctrl-C.

Simply invoke orderBy() as many times as you need it. For instance:

User::orderBy('name', 'DESC')
    ->orderBy('email', 'ASC')
    ->get();

Produces the following query:

SELECT * FROM `users` ORDER BY `name` DESC, `email` ASC

You can use the IIf function too:

CheckIt = IIf(TestMe > 1000, "Large", "Small")

You can add the image into a comment.

Right-click cell > Insert Comment > right-click on shaded (grey area) on outside of comment box > Format Comment > Colors and Lines > Fill > Color > Fill Effects > Picture > (Browse to picture) > Click OK

Image will appear on hover over.

Microsoft Office 365 (2019) introduced new things called comments and renamed the old comments as "notes". Therefore in the steps above do New Note instead of Insert Comment. All other steps remain the same and the functionality still exists.

There is also a $20 product for Windows - Excel Image Assistant...

I happened to notice the solution given below. In found it my research for the same issue. I don't who had posted it but it wasn't made by me. It uses jQuery:

$(document).ready(function() {
    $(":checkbox").bind("click", false);
});

This would make the checkboxes read only which would be helpful for showing readonly data to the client.

According to your example here it seems that they both reside in the same namespace, i conclude that they are both part of the same project ( if you haven't created another project with the same namespace) and all class by default are defined as internal to the project they are defined in, if haven't declared otherwise, therefore i guess the problem is that your file is not included in your project. You can include it by right clicking the file in the solution explorer window => Include in project, if you cannot see the file inside the project files in the solution explorer then click the show the upper menu button of the solution explorer called show all files ( just hove your mouse cursor over the button there and you'll see the names of the buttons)

Just for basic knowledge: If the file resides in a different project\ assembly then it has to be defined, otherwise it has to be define at least as internal or public. in case your class is inheriting from that class that it can be protected as well.

There should be a line in your postgresql.conf file that says:

port = 1486

Change that.

The location of the file can vary depending on your install options. On Debian-based distros it is /etc/postgresql/8.3/main/

On Windows it is C:\Program Files\PostgreSQL\9.3\data

Don't forget to sudo service postgresql restart for changes to take effect.

Pretty easy, go to the 'scripts' tab. And select the source file you want and double-click any line to edit it.

From RFC 6750, Section 1.2:

Bearer Token

A security token with the property that any party in possession of the token (a "bearer") can use the token in any way that any other party in possession of it can. Using a bearer token does not require a bearer to prove possession of cryptographic key material (proof-of-possession).

The Bearer Token or Refresh token is created for you by the Authentication server. When a user authenticates your application (client) the authentication server then goes and generates for your a Bearer Token (refresh token) which you can then use to get an access token.

The Bearer Token is normally some kind of cryptic value created by the authentication server, it isn't random it is created based upon the user giving you access and the client your application getting access.

To get rid of permission errors (and such), you can redirect stderr to nowhere

find / -name "something" 2>/dev/null

try this script..

#!/bin/bash
NULL="_"
for f in `svn st|grep -v ^\?|sed s/.\ *//`; 
     do LIST="${LIST} $f $NULL on"; 
done
dialog --checklist "Select files to commit" 30 60 30 $LIST 2>/tmp/svnlist.txt
svn ci `cat /tmp/svnlist.txt|sed 's/"//g'`

Update: Disabling the href works better in the link function return. Code below has been updated.

aDisabled naturally executes before ngClick because directives are sorted in alphabetical order. When aDisabled is renamed to tagDisabled, the directive does not work.

To "disable" the "a" tag, I'd want the following things:

1. href links not to be followed when clicked
2. ngClick events not to fire when clicked
3. styles changed by adding a disabled class

This directive does this by mimicking the ngDisabled directive. Based on the value of a-disabled directive, all of the above features are toggled.

myApp.directive('aDisabled', function() {
    return {
        compile: function(tElement, tAttrs, transclude) {
            //Disable ngClick
            tAttrs["ngClick"] = "!("+tAttrs["aDisabled"]+") && ("+tAttrs["ngClick"]+")";

            //return a link function
            return function (scope, iElement, iAttrs) {

                //Toggle "disabled" to class when aDisabled becomes true
                scope.$watch(iAttrs["aDisabled"], function(newValue) {
                    if (newValue !== undefined) {
                        iElement.toggleClass("disabled", newValue);
                    }
                });

                //Disable href on click
                iElement.on("click", function(e) {
                    if (scope.$eval(iAttrs["aDisabled"])) {
                        e.preventDefault();
                    }
                });
            };
        }
    };
});

Here is a css style that might indicate a disabled tag:

a.disabled {
    color: #AAAAAA;
    cursor: default;
    pointer-events: none;
    text-decoration: none;
}

And here is the code in action, with your example

Take a look at Datejs for all those petty date related issues.. You could solve this by parseDate function too

I posted this question and never saw the feedback (which came in several months after, it seems :).

As Kinlan mentioned, ALLOW-FROM is not supported in all browsers as an X-Frame-Options value.

The solution was to branch based on browser type. For IE, ship X-Frame-Options. For everyone else, ship X-Content-Security-Policy.

Hope this helps, and sorry for taking so long to close the loop!

Consider creating an index. A dictionary can do the trick. If you need the list semantics, subclass and keep the index as a private member...

I start standalone instance in my machine, and encounter the same problem. Finally, I change from ip "127.0.0.1" to "localhost" and the problem is gone.

Alternatively you could read you csv with header=None and then add it with df.columns:

Cov = pd.read_csv("path/to/file.txt", sep='\t', header=None)
Cov.columns = ["Sequence", "Start", "End", "Coverage"]

So why don't you simply use a key-value literal?

var params = {
    'slide0001.html': 'Looking Ahead',
    'slide0002.html': 'Forecase',
    ...
};

return params['slide0001.html']; // returns: Looking Ahead

Worked for me in 30 seconds, short and sweet:

1. In IIS Manager (run inetmgr)
2. Go to ApplicationPool -> Advanced Settings
3. Set ApplicationPoolIdentity to NetworkService
4. Go to the file, right click properties, go to security, click edit, click add, enter Network Service (with space, then click 'check names'), and give full control (or just whatever permissions you need)

The RFCs are known not to reflect reality.

If this is a simple project, you should be able to drag the txt file right into the project folder. Specifically, the "project folder" would be the highest level folder. I tried to do this (for a homework project that I'm doing) by putting the txt file in the src folder, but that didn't work. But finally I figured out to put it in the project file.

A good tutorial for this is http://www.vogella.com/articles/JavaIO/article.html. I used this as an intro to i/o and it helped.
