I tried the @Alexander Farber and @Sino Raj answers. Both answers are nice, but I couldn't use the onCreateOptionsMenu inside my fragment, until I discover what was missing:

Add setSupportActionBar(toolbar) in my Activity, like this:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.id.activity_main);

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
}

I hope this answer can be helpful for someone with the same problem.

I've also used the InternalsVisibleToAttribute method. It's worth mentioning too that, if you feel uncomfortable making your previously private methods internal in order to achieve this, then maybe they should not be the subject of direct unit tests anyway.

After all, you're testing the behaviour of your class, rather than it's specific implementation - you can change the latter without changing the former and your tests should still pass.

If direct casting shows error you can do it like this:

Long id = 100;
int int_id = (int) (id % 100000);

To use CurrentDb.Execute, your query must be an action query, AND in quotes.

CurrentDb.Execute "queryname"

As @daniel-t points out in the comment: github.com/docker/docker/issues/2174 is about showing binding only to IPv6 in netstat, but that is not an issue. As that github issues states:

When setting up the proxy, Docker requests the loopback address '127.0.0.1', Linux realises this is an address that exists in IPv6 (as ::0) and opens on both (but it is formally an IPv6 socket). When you run netstat it sees this and tells you it is an IPv6 - but it is still listening on IPv4. If you have played with your settings a little, you may have disabled this trick Linux does - by setting net.ipv6.bindv6only = 1.

In other words, just because you see it as IPv6 only, it is still able to communicate on IPv4 unless you have IPv6 set to only bind on IPv6 with the net.ipv6.bindv6only setting. To be clear, net.ipv6.bindv6only should be 0 - you can run sysctl net.ipv6.bindv6only to verify.

Generic way to update the any JSONObjet with new values.

private static void updateJsonValues(JsonObject jsonObj) {
    for (Map.Entry<String, JsonElement> entry : jsonObj.entrySet()) {
        JsonElement element = entry.getValue();
        if (element.isJsonArray()) {
            parseJsonArray(element.getAsJsonArray());
        } else if (element.isJsonObject()) {
            updateJsonValues(element.getAsJsonObject());
        } else if (element.isJsonPrimitive()) {
            jsonObj.addProperty(entry.getKey(), "<provide new value>");
        }

    }
}

private static void parseJsonArray(JsonArray asJsonArray) {
    for (int index = 0; index < asJsonArray.size(); index++) {
        JsonElement element = asJsonArray.get(index);
        if (element.isJsonArray()) {
            parseJsonArray(element.getAsJsonArray());
        } else if (element.isJsonObject()) {
            updateJsonValues(element.getAsJsonObject());
        }

    }
}

So - the solution of providing a base works given that all of the paths have the same base path. But if you want to provide different base paths, this still won't work.

One way I solved this problem was by making the beginning of the path relative. For your case:

gulp.src([
    'index.php',
    '*css/**/*',
    '*js/**/*',
    '*src/**/*',
])
.pipe(gulp.dest('/var/www/'));

The reason this works is that Gulp sets the base to be the end of the first explicit chunk - the leading * causes it to set the base at the cwd (which is the result that we all want!)

This only works if you can ensure your folder structure won't have certain paths that could match twice. For example, if you had randomjs/ at the same level as js, you would end up matching both.

This is the only way that I have found to include these as part of a top-level gulp.src function. It would likely be simple to create a plugin/function that could separate out each of those globs so you could specify the base directory for them, however.

There is an isConnected function in BluetoothDevice system API in https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/BluetoothDevice.java

If you want to know if the a bounded(paired) device is currently connected or not, the following function works fine for me:

public static boolean isConnected(BluetoothDevice device) {
    try {
        Method m = device.getClass().getMethod("isConnected", (Class[]) null);
        boolean connected = (boolean) m.invoke(device, (Object[]) null);
        return connected;
    } catch (Exception e) {
        throw new IllegalStateException(e);
    }
}

Even though you asked for wait() and notify() specifically, I feel that this quote is still important enough:

Josh Bloch, Effective Java 2nd Edition, Item 69: Prefer concurrency utilities to wait and notify (emphasis his):

Given the difficulty of using wait and notify correctly, you should use the higher-level concurrency utilities instead [...] using wait and notify directly is like programming in "concurrency assembly language", as compared to the higher-level language provided by java.util.concurrent. There is seldom, if ever, reason to use wait and notify in new code.

The command has to be entered in the directory of the repository. The error is complaining that your current directory isn't a git repo

1. Are you in the right directory? Does typing ls show the right files?
2. Have you initialized the repository yet? Typed git init? (git-init documentation)

Either of those would cause your error.

Following code works..

datePickerButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            showDialog(0);
        }
    });

@Override
@Deprecated
protected Dialog onCreateDialog(int id) {
    return new DatePickerDialog(this, datePickerListener, year, month, day);
}

private DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() {
    public void onDateSet(DatePicker view, int selectedYear,
                          int selectedMonth, int selectedDay) {
        day = selectedDay;
        month = selectedMonth;
        year = selectedYear;
        datePickerButton.setText(selectedDay + " / " + (selectedMonth + 1) + " / "
                + selectedYear);
    }
};

To a great extent, that's someone elevating their own weaknesses to a general rule. There's nothing wrong per se with creating objects using the new operator. What there is some argument for is that you have to do so with some discipline: if you create an object you need to make sure it's going to be destroyed.

The easiest way of doing that is to create the object in automatic storage, so C++ knows to destroy it when it goes out of scope:

 {
    File foo = File("foo.dat");

    // do things

 }

Now, observe that when you fall off that block after the end-brace, foo is out of scope. C++ will call its dtor automatically for you. Unlike Java, you don't need to wait for the GC to find it.

Had you written

 {
     File * foo = new File("foo.dat");

you would want to match it explicitly with

     delete foo;
  }

or even better, allocate your File * as a "smart pointer". If you aren't careful about that it can lead to leaks.

The answer itself makes the mistaken assumption that if you don't use new you don't allocate on the heap; in fact, in C++ you don't know that. At most, you know that a small amout of memory, say one pointer, is certainly allocated on the stack. However, consider if the implementation of File is something like

  class File {
    private:
      FileImpl * fd;
    public:
      File(String fn){ fd = new FileImpl(fn);}

then FileImpl will still be allocated on the stack.

And yes, you'd better be sure to have

     ~File(){ delete fd ; }

in the class as well; without it, you'll leak memory from the heap even if you didn't apparently allocate on the heap at all.

Tested in Python 3.3.2 There are many ways to accomplish this, here's one of the shortest, using only python-provided stuff:

import base64
hex_data ='57696C6C20796F7520636F6E76657274207468697320484558205468696E6720696E746F20415343494920666F72206D653F2E202E202E202E506C656565656173652E2E2E212121'
ascii_string = str(base64.b16decode(hex_data))[2:-1]
print (ascii_string)

Of course, if you don't want to import anything, you can always write your own code. Something very basic like this:

ascii_string = ''
x = 0
y = 2
l = len(hex_data)
while y <= l:
    ascii_string += chr(int(hex_data[x:y], 16))
    x += 2
    y += 2
print (ascii_string)

you can use this snippet =>

 const timerCountDown = async () => {
    let date = new Date();
    let time = date.getTime() + 122000;
    let countDownDate = new Date(time).getTime();
    let x = setInterval(async () => {
      let now = new Date().getTime();
      let distance = countDownDate - now;
      let days = Math.floor(distance / (1000 * 60 * 60 * 24));
      let hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
      let minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60));
      let seconds = Math.floor((distance % (1000 * 60)) / 1000);

      if (distance < 1000) {
        // ================== Timer Finished 
        clearInterval(x);
      }
    }, 1000);
  };

The best way is to use different database groups. If you want to keep using the master database as usual ($this->db) just turn off persistent connexion configuration option to your secondary database(s). Only master database should work with persistent connexion :

Master database

$db['default']['hostname'] = "localhost";
$db['default']['username'] = "root";
$db['default']['password'] = "";
$db['default']['database'] = "database_name";
$db['default']['dbdriver'] = "mysql";
$db['default']['dbprefix'] = "";
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = FALSE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = "";
$db['default']['char_set'] = "utf8";
$db['default']['dbcollat'] = "utf8_general_ci";
$db['default']['swap_pre'] = "";
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;

Secondary database (notice pconnect is set to false)

$db['otherdb']['hostname'] = "localhost";
$db['otherdb']['username'] = "root";
$db['otherdb']['password'] = "";
$db['otherdb']['database'] = "other_database_name";
$db['otherdb']['dbdriver'] = "mysql";
$db['otherdb']['dbprefix'] = "";
$db['otherdb']['pconnect'] = FALSE;
$db['otherdb']['db_debug'] = FALSE;
$db['otherdb']['cache_on'] = FALSE;
$db['otherdb']['cachedir'] = "";
$db['otherdb']['char_set'] = "utf8";
$db['otherdb']['dbcollat'] = "utf8_general_ci";
$db['otherdb']['swap_pre'] = "";
$db['otherdb']['autoinit'] = TRUE;
$db['otherdb']['stricton'] = FALSE;

Then you can use secondary databases as database objects while using master database as usual :

// use master dataabse
$users = $this->db->get('users');

// connect to secondary database
$otherdb = $this->load->database('otherdb', TRUE);
$stuff = $otherdb->get('struff');
$otherdb->insert_batch('users', $users->result_array());

// keep using master database as usual, for example insert stuff from other database
$this->db->insert_batch('stuff', $stuff->result_array());

What about:

.close-image{
    display:block;
    cursor:pointer;
    z-index:3;
    position:absolute;
    top:0;
    right:0;
}

Is that the desired result?

I have reformatted your code.

The error was situated in this line :

printf("%d", (**c));

To fix it, change to :

printf("%d", (*c));

The * retrieves the value from an address. The ** retrieves the value (an address in this case) of an other value from an address.

In addition, the () was optional.

#include <stdio.h>

int main(void)
{
    int b = 10; 
    int *a = NULL;
    int *c = NULL;

    a = &b;
    c = &a;

    printf("%d", *c);

    return 0;
} 

EDIT :

The line :

c = &a;

must be replaced by :

c = a;

It means that the value of the pointer 'c' equals the value of the pointer 'a'. So, 'c' and 'a' points to the same address ('b'). The output is :

10

EDIT 2:

If you want to use a double * :

#include <stdio.h>

int main(void)
{
    int b = 10; 
    int *a = NULL;
    int **c = NULL;

    a = &b;
    c = &a;

    printf("%d", **c);

    return 0;
} 

Output:

10

If the variable ax.xaxis._autolabelpos = True, matplotlib sets the label position in function _update_label_position in axis.py according to (some excerpts):

    bboxes, bboxes2 = self._get_tick_bboxes(ticks_to_draw, renderer)
    bbox = mtransforms.Bbox.union(bboxes)
    bottom = bbox.y0
    x, y = self.label.get_position()
    self.label.set_position((x, bottom - self.labelpad * self.figure.dpi / 72.0))

You can set the label position independently of the ticks by using:

    ax.xaxis.set_label_coords(x0, y0)

that sets _autolabelpos to False or as mentioned above by changing the labelpad parameter.

When you pass a string to the filter function, the string is interpreted as SQL. Count is a SQL keyword and using count as a variable confuses the parser. This is a small bug (you can file a JIRA ticket if you want to).

You can easily avoid this by using a column expression instead of a String:

df.groupBy("x").count()
  .filter($"count" >= 2)
  .show()

If you are using python3 on windows then you might do this as well

pip3 install tensorflow==1.4

you may select any version from "(from versions: 1.2.0rc2, 1.2.0, 1.2.1, 1.3.0rc0, 1.3.0rc1, 1.3.0rc2, 1.3.0, 1.4.0rc0, 1.4.0rc1, 1.4.0, 1.5.0rc0, 1.5.0rc1, 1.5.0, 1.5.1, 1.6.0rc0, 1.6.0rc1, 1.6.0, 1.7.0rc0, 1.7.0rc1, 1.7.0)"

I did this when I wanted to downgrade from 1.7 to 1.4

Here is a quick DOM example that shows how to read and write a simple xml file with its dtd:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE roles SYSTEM "roles.dtd">
<roles>
    <role1>User</role1>
    <role2>Author</role2>
    <role3>Admin</role3>
    <role4/>
</roles>

and the dtd:

<?xml version="1.0" encoding="UTF-8"?>
<!ELEMENT roles (role1,role2,role3,role4)>
<!ELEMENT role1 (#PCDATA)>
<!ELEMENT role2 (#PCDATA)>
<!ELEMENT role3 (#PCDATA)>
<!ELEMENT role4 (#PCDATA)>

First import these:

import javax.xml.parsers.*;
import javax.xml.transform.*;
import javax.xml.transform.dom.*;
import javax.xml.transform.stream.*;
import org.xml.sax.*;
import org.w3c.dom.*;

Here are a few variables you will need:

private String role1 = null;
private String role2 = null;
private String role3 = null;
private String role4 = null;
private ArrayList<String> rolev;

Here is a reader (String xml is the name of your xml file):

public boolean readXML(String xml) {
        rolev = new ArrayList<String>();
        Document dom;
        // Make an  instance of the DocumentBuilderFactory
        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        try {
            // use the factory to take an instance of the document builder
            DocumentBuilder db = dbf.newDocumentBuilder();
            // parse using the builder to get the DOM mapping of the    
            // XML file
            dom = db.parse(xml);

            Element doc = dom.getDocumentElement();

            role1 = getTextValue(role1, doc, "role1");
            if (role1 != null) {
                if (!role1.isEmpty())
                    rolev.add(role1);
            }
            role2 = getTextValue(role2, doc, "role2");
            if (role2 != null) {
                if (!role2.isEmpty())
                    rolev.add(role2);
            }
            role3 = getTextValue(role3, doc, "role3");
            if (role3 != null) {
                if (!role3.isEmpty())
                    rolev.add(role3);
            }
            role4 = getTextValue(role4, doc, "role4");
            if ( role4 != null) {
                if (!role4.isEmpty())
                    rolev.add(role4);
            }
            return true;

        } catch (ParserConfigurationException pce) {
            System.out.println(pce.getMessage());
        } catch (SAXException se) {
            System.out.println(se.getMessage());
        } catch (IOException ioe) {
            System.err.println(ioe.getMessage());
        }

        return false;
    }

And here a writer:

public void saveToXML(String xml) {
    Document dom;
    Element e = null;

    // instance of a DocumentBuilderFactory
    DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
    try {
        // use factory to get an instance of document builder
        DocumentBuilder db = dbf.newDocumentBuilder();
        // create instance of DOM
        dom = db.newDocument();

        // create the root element
        Element rootEle = dom.createElement("roles");

        // create data elements and place them under root
        e = dom.createElement("role1");
        e.appendChild(dom.createTextNode(role1));
        rootEle.appendChild(e);

        e = dom.createElement("role2");
        e.appendChild(dom.createTextNode(role2));
        rootEle.appendChild(e);

        e = dom.createElement("role3");
        e.appendChild(dom.createTextNode(role3));
        rootEle.appendChild(e);

        e = dom.createElement("role4");
        e.appendChild(dom.createTextNode(role4));
        rootEle.appendChild(e);

        dom.appendChild(rootEle);

        try {
            Transformer tr = TransformerFactory.newInstance().newTransformer();
            tr.setOutputProperty(OutputKeys.INDENT, "yes");
            tr.setOutputProperty(OutputKeys.METHOD, "xml");
            tr.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
            tr.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM, "roles.dtd");
            tr.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "4");

            // send DOM to file
            tr.transform(new DOMSource(dom), 
                                 new StreamResult(new FileOutputStream(xml)));

        } catch (TransformerException te) {
            System.out.println(te.getMessage());
        } catch (IOException ioe) {
            System.out.println(ioe.getMessage());
        }
    } catch (ParserConfigurationException pce) {
        System.out.println("UsersXML: Error trying to instantiate DocumentBuilder " + pce);
    }
}

getTextValue is here:

private String getTextValue(String def, Element doc, String tag) {
    String value = def;
    NodeList nl;
    nl = doc.getElementsByTagName(tag);
    if (nl.getLength() > 0 && nl.item(0).hasChildNodes()) {
        value = nl.item(0).getFirstChild().getNodeValue();
    }
    return value;
}

Add a few accessors and mutators and you are done!

std::string stringify(double x)
 {
   std::ostringstream o;
   if (!(o << x))
     throw BadConversion("stringify(double)");
   return o.str();
 }

C++ FAQ: http://www.parashift.com/c++-faq-lite/misc-technical-issues.html#faq-39.1

You're only noticing that because you are selecting a single column.

Try selecting two fields and see what happens.

Group By is intended to be used like this:

SELECT name, SUM(transaction) FROM myTbl GROUP BY name

Which would show the sum of all transactions for each person.

As a general statement, its good to make your if conditionals as readable as possible. For your example, using ! is ok. the problem is when things look like

if ((a.b && c.d.e) || !f)

you might want to do something like

bool isOk = a.b;
bool isStillOk = c.d.e
bool alternateOk = !f

then your if statement is simplified to

if ( (isOk && isStillOk) || alternateOk)

It just makes the code more readable. And if you have to debug, you can debug the isOk set of vars instead of having to dig through the variables in scope. It is also helpful for dealing with NPEs -- breaking code out into simpler chunks is always good.

You can make use of the beforeunload event in JavaScript.

Using vanilla JavaScript you could do something like:

window.onbeforeunload = function() {
  localStorage.removeItem(key);
  return '';
};

That will delete the key before the browser window/tab is closed and prompts you to confirm the close window/tab action. I hope that solves your problem.

NOTE: The onbeforeunload method should return a string.

This worked for me. I made a function. Put this in your shell script:

sshcmd(){
    ssh $1@$2 $3
}

sshcmd USER HOST COMMAND

If you have multiple machines that you want to do the same command on you would repeat that line with a semi colon. For example, if you have two machines you would do this:

sshcmd USER HOST COMMAND ; sshcmd USER HOST COMMAND

Replace USER with the user of the computer. Replace HOST with the name of the computer. Replace COMMAND with the command you want to do on the computer.

Hope this helps!

if all things were said didn't work, go back to basics and test if this is working:

<html>
  <head>
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script>
  </head>
  <body>
    <script type="text/javascript">
      $('body').click(function() {
        // do something here like:
        alert('hey! The body click is working!!!')
      });
    </script>
  </body>
</html>

then tell me if its working or not.

I had a similar problem that I solved by using the following sequence:

1. use the CELL("filename") function to get the full path to the current sheet of the current file.

2. use the SEARCH() function to find the start of the [FileName]SheetName string of your current excel file and the sheet.

3. use the LEFT function to extract the full path name of the directory that contains your current file.

4. Concatenate the directory path name found in step #3 with the name of the file, the name of the worksheet, and the cell reference that you want to access.

5. use the INDIRECT() function to access the CellPathName that you created in step #4.

Note: these same steps can also be used to access cells in files whose names are created dynamically. In step #4, use a text string that is dynamically created from the contents of cells, the current date or time, etc. etc.

A cell reference example (with each piece assembled separately) that includes all of these steps is:

=INDIRECT("'" & LEFT(CELL("filename"),SEARCH("[MyFileName]MySheetName",CELL("filename")) - 1) & "[" & "OtherFileName" & "]" & "OtherSheetName" & "'!" & "$OtherColumn$OtherRow" & "'")

Note that LibreOffice uses a slightly different CellPatnName syntax, as in the following example:

=INDIRECT(LEFT(CELL("filename"),SEARCH("[MyFileName]MySheetName",CELL("filename")) - 1) & "OtherFileName" & "'#$" & "OtherSheetName" & "." & "$OtherColumn$OtherRow")

The problem is you're not doing anything with the result of replace. In Python strings are immutable so anything that manipulates a string returns a new string instead of modifying the original string.

line[8] = line[8].replace(letter, "")

If you need to find values for variables other than those standard VS macros, you could do that easily using Process Explorer. Start it, find the process your Visual Studio instance runs in, right click, Properties ? Environment. It lists all those $ vars as key-value pairs:

Try:

123-(?:(apple|banana|)-|)456

That will match apple, banana, or a blank string, and following it there will be a 0 or 1 hyphens. I was wrong about not having a need for a capturing group. Silly me.

Thread represents an actual OS-level thread, with its own stack and kernel resources. (technically, a CLR implementation could use fibers instead, but no existing CLR does this) Thread allows the highest degree of control; you can Abort() or Suspend() or Resume() a thread (though this is a very bad idea), you can observe its state, and you can set thread-level properties like the stack size, apartment state, or culture.

The problem with Thread is that OS threads are costly. Each thread you have consumes a non-trivial amount of memory for its stack, and adds additional CPU overhead as the processor context-switch between threads. Instead, it is better to have a small pool of threads execute your code as work becomes available.

There are times when there is no alternative Thread. If you need to specify the name (for debugging purposes) or the apartment state (to show a UI), you must create your own Thread (note that having multiple UI threads is generally a bad idea). Also, if you want to maintain an object that is owned by a single thread and can only be used by that thread, it is much easier to explicitly create a Thread instance for it so you can easily check whether code trying to use it is running on the correct thread.

ThreadPool

ThreadPool is a wrapper around a pool of threads maintained by the CLR. ThreadPool gives you no control at all; you can submit work to execute at some point, and you can control the size of the pool, but you can't set anything else. You can't even tell when the pool will start running the work you submit to it.

Using ThreadPool avoids the overhead of creating too many threads. However, if you submit too many long-running tasks to the threadpool, it can get full, and later work that you submit can end up waiting for the earlier long-running items to finish. In addition, the ThreadPool offers no way to find out when a work item has been completed (unlike Thread.Join()), nor a way to get the result. Therefore, ThreadPool is best used for short operations where the caller does not need the result.

Task

Finally, the Task class from the Task Parallel Library offers the best of both worlds. Like the ThreadPool, a task does not create its own OS thread. Instead, tasks are executed by a TaskScheduler; the default scheduler simply runs on the ThreadPool.

Unlike the ThreadPool, Task also allows you to find out when it finishes, and (via the generic Task) to return a result. You can call ContinueWith() on an existing Task to make it run more code once the task finishes (if it's already finished, it will run the callback immediately). If the task is generic, ContinueWith() will pass you the task's result, allowing you to run more code that uses it.

You can also synchronously wait for a task to finish by calling Wait() (or, for a generic task, by getting the Result property). Like Thread.Join(), this will block the calling thread until the task finishes. Synchronously waiting for a task is usually bad idea; it prevents the calling thread from doing any other work, and can also lead to deadlocks if the task ends up waiting (even asynchronously) for the current thread.

Since tasks still run on the ThreadPool, they should not be used for long-running operations, since they can still fill up the thread pool and block new work. Instead, Task provides a LongRunning option, which will tell the TaskScheduler to spin up a new thread rather than running on the ThreadPool.

All newer high-level concurrency APIs, including the Parallel.For*() methods, PLINQ, C# 5 await, and modern async methods in the BCL, are all built on Task.

Conclusion

The bottom line is that Task is almost always the best option; it provides a much more powerful API and avoids wasting OS threads.

The only reasons to explicitly create your own Threads in modern code are setting per-thread options, or maintaining a persistent thread that needs to maintain its own identity.

How about less /var/log/syslog?

I just wrote a quick function to do this. I needed it to handle many forms so I made it so it will accept a string separated by ','.

//function to make sure that all of the required fields of a post are sent. Returns True for error and False for NO error  
//accepts a string that is then parsed by "," into an array. The array is then checked for empty values.
function errorPOSTEmpty($stringOfFields) {
        $error = false;
            if(!empty($stringOfFields)) {
                // Required field names
                $required = explode(',',$stringOfFields);
                // Loop over field names
                foreach($required as $field) {
                  // Make sure each one exists and is not empty
                  if (empty($_POST[$field])) {
                    $error = true;
                    // No need to continue loop if 1 is found.
                    break;
                  }
                }
            }
    return $error;
}

So you can enter this function in your code, and handle errors on a per page basis.

$postError = errorPOSTEmpty('login,password,confirm,name,phone,email');

if ($postError === true) {
  ...error code...
} else {
  ...vars set goto POSTing code...
}

FYI, it looks like the syntax for retrieving the values has changed according to:

http://freemarker.sourceforge.net/docs/ref_builtins_hash.html

<#assign h = {"name":"mouse", "price":50}>
<#assign keys = h?keys>
<#list keys as key>${key} = ${h[key]}; </#list>

Same thing, Just start the table name with # or ##:

CREATE TABLE #TemporaryTable          -- Local temporary table - starts with single #
(
    Col1 int,
    Col2 varchar(10)
    ....
);

CREATE TABLE ##GlobalTemporaryTable   -- Global temporary table - note it starts with ##.
(
    Col1 int,
    Col2 varchar(10)
    ....
);

Temporary table names start with # or ## - The first is a local temporary table and the last is a global temporary table.

Here is one of many articles describing the differences between them.

This should work for you:

    $('.SeeMore2').click(function(){
        var $this = $(this);
        $this.toggleClass('SeeMore2');
        if($this.hasClass('SeeMore2')){
            $this.text('See More');         
        } else {
            $this.text('See Less');
        }
});

for those who want to show collapsible json can use renderjson

Here is the example by embedding the render js javascript in html

        // Usage
        // -----
        // The module exports one entry point, the `renderjson()` function. It takes in
        // the JSON you want to render as a single argument and returns an HTML
        // element.
        //
        // Options
        // -------
        // renderjson.set_icons("+", "-")
        //   This Allows you to override the disclosure icons.
        //
        // renderjson.set_show_to_level(level)
        //   Pass the number of levels to expand when rendering. The default is 0, which
        //   starts with everything collapsed. As a special case, if level is the string
        //   "all" then it will start with everything expanded.
        //
        // renderjson.set_max_string_length(length)
        //   Strings will be truncated and made expandable if they are longer than
        //   `length`. As a special case, if `length` is the string "none" then
        //   there will be no truncation. The default is "none".
        //
        // renderjson.set_sort_objects(sort_bool)
        //   Sort objects by key (default: false)
        //
        // Theming
        // -------
        // The HTML output uses a number of classes so that you can theme it the way
        // you'd like:
        //     .disclosure    ("?", "?")
        //     .syntax        (",", ":", "{", "}", "[", "]")
        //     .string        (includes quotes)
        //     .number
        //     .boolean
        //     .key           (object key)
        //     .keyword       ("null", "undefined")
        //     .object.syntax ("{", "}")

git stash pop

will get everything back in place

as suggested in the comments, you can use git stash branch newbranch to apply the stash to a new branch, which is the same as running:

git checkout -b newbranch
git stash pop

You can also try ternary operator. Something like this

{{data.id === 5 ? "it's true" : "it's false"}}

Change your html code little bit and try this hope so it will be work for you.

You do not have to use sc.textFile(...) to convert local files into dataframes. One of options is, to read a local file line by line and then transform it into Spark Dataset. Here is an example for Windows machine in Java:

StructType schemata = DataTypes.createStructType(
            new StructField[]{
                    createStructField("COL1", StringType, false),
                    createStructField("COL2", StringType, false),
                    ...
            }
    );

String separator = ";";
String filePath = "C:\\work\\myProj\\myFile.csv";
SparkContext sparkContext = new SparkContext(new SparkConf().setAppName("MyApp").setMaster("local"));
JavaSparkContext jsc = new JavaSparkContext (sparkContext );
SQLContext sqlContext = SQLContext.getOrCreate(sparkContext );

List<String[]> result = new ArrayList<>();
try (BufferedReader br = new BufferedReader(new FileReader(filePath))) {
    String line;
    while ((line = br.readLine()) != null) {
      String[] vals = line.split(separator);
      result.add(vals);
    }
 } catch (Exception ex) {
       System.out.println(ex.getMessage());
       throw new RuntimeException(ex);
  }
  JavaRDD<String[]> jRdd = jsc.parallelize(result);
  JavaRDD<Row> jRowRdd = jRdd .map(RowFactory::create);
  Dataset<Row> data = sqlContext.createDataFrame(jRowRdd, schemata);

Now you can use dataframe data in your code.

/* Most Accurate Setting if you only want
   to do this with CSS Pseudo Element */
p:before { 
   content: "\00a0";
   padding-right: 5px; /* If you need more space b/w contents */
}

The Dir function is the way to go, but the problem is that you cannot use the Dir function recursively, as stated here, towards the bottom.

The way that I've handled this is to use the Dir function to get all of the sub-folders for the target folder and load them into an array, then pass the array into a function that recurses.

Here's a class that I wrote that accomplishes this, it includes the ability to search for filters. (You'll have to forgive the Hungarian Notation, this was written when it was all the rage.)

Private m_asFilters() As String
Private m_asFiles As Variant
Private m_lNext As Long
Private m_lMax As Long

Public Function GetFileList(ByVal ParentDir As String, Optional ByVal sSearch As String, Optional ByVal Deep As Boolean = True) As Variant
    m_lNext = 0
    m_lMax = 0

    ReDim m_asFiles(0)
    If Len(sSearch) Then
        m_asFilters() = Split(sSearch, "|")
    Else
        ReDim m_asFilters(0)
    End If

    If Deep Then
        Call RecursiveAddFiles(ParentDir)
    Else
        Call AddFiles(ParentDir)
    End If

    If m_lNext Then
        ReDim Preserve m_asFiles(m_lNext - 1)
        GetFileList = m_asFiles
    End If

End Function

Private Sub RecursiveAddFiles(ByVal ParentDir As String)
    Dim asDirs() As String
    Dim l As Long
    On Error GoTo ErrRecursiveAddFiles

For a start the first select has 6 columns and the second has 4 columns. Perhaps make both have the same number of columns (adding nulls?).

The STAThreadAttribute is essentially a requirement for the Windows message pump to communicate with COM components. Although core Windows Forms does not use COM, many components of the OS such as system dialogs do use this technology.

MSDN explains the reason in slightly more detail:

STAThreadAttribute indicates that the COM threading model for the application is single-threaded apartment. This attribute must be present on the entry point of any application that uses Windows Forms; if it is omitted, the Windows components might not work correctly. If the attribute is not present, the application uses the multithreaded apartment model, which is not supported for Windows Forms.

This blog post (Why is STAThread required?) also explains the requirement quite well. If you want a more in-depth view as to how the threading model works at the CLR level, see this MSDN Magazine article from June 2004 (Archived, Apr. 2009).

You shouldn't really do this but insert in a new record instead and update it that way.
But, if you really need to, you can do the following:

• Disable enforcing FK constraints temporarily (e.g. ALTER TABLE foo WITH NOCHECK CONSTRAINT ALL)
• Then update your PK
• Then update your FKs to match the PK change
• Finally enable back enforcing FK constraints

SimpleDateFormat simpleDateFormat = new SimpleDateFormat("HH:MM");
simpleDateFormat.format(fajr_prayertime);

This is what I've tried and it works fine in ff, chrome and ie8:

/* set width for the <fb:like> tag */

.fb-button {
    width:51px;
}

/* set width for the iframe below, to hide the count label*/

.fb-button iframe{
    width:45px!important;
}

I've had good success using Mockito.

When I tried learning about JMock and EasyMock, I found the learning curve to be a bit steep (though maybe that's just me).

I like Mockito because of its simple and clean syntax that I was able to grasp pretty quickly. The minimal syntax is designed to support the common cases very well, although the few times I needed to do something more complicated I found what I wanted was supported and easy to grasp.

Here's an (abridged) example from the Mockito homepage:

import static org.mockito.Mockito.*;

List mockedList = mock(List.class);
mockedList.clear();
verify(mockedList).clear();

It doesn't get much simpler than that.

The only major downside I can think of is that it won't mock static methods.

Updated Answer

As of June11, 2018 it is now mandatory to have a billing account to get API key. You can still make keyless calls to the Maps JavaScript API and Street View Static API which will return low-resolution maps that can be used for development. Enabling billing still gives you $200 free credit monthly for your projects.

This answer is no longer valid

As long as you're using a testing API key it is free to register and use. But when you move your app to commercial level you have to pay for it. When you enable billing, google gives you $200 credit free each month that means if your app's map usage is low you can still use it for free even after the billing enabled, if it exceeds the credit limit now you have to pay for it.

You can add

from functools import reduce

before you use the reduce.

To first force HTTPS, you must check the correct environment variable %{HTTPS} off, but your rule above then prepends the www. Since you have a second rule to enforce www., don't use it in the first rule.

RewriteEngine On
RewriteCond %{HTTPS} off
# First rewrite to HTTPS:
# Don't put www. here. If it is already there it will be included, if not
# the subsequent rule will catch it.
RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
# Now, rewrite any request to the wrong domain to use www.
# [NC] is a case-insensitive match
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule .* https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

About proxying

When behind some forms of proxying, whereby the client is connecting via HTTPS to a proxy, load balancer, Passenger application, etc., the %{HTTPS} variable may never be on and cause a rewrite loop. This is because your application is actually receiving plain HTTP traffic even though the client and the proxy/load balancer are using HTTPS. In these cases, check the X-Forwarded-Proto header instead of the %{HTTPS} variable. This answer shows the appropriate process

This is what I did for my app. If you take a look at the following classes in the bootstrap.css file .modal-dialog has a default padding of 10px and @media screen and (min-width: 768px) .modal-dialog has a top padding set to 30px. So in my custom css file I set my top padding to be 15% for all screens without specifying a media screen width. Hope this helps.

.modal-dialog {
  padding-top: 15%;
}

A very good solution to this can be found here:

Here's a class that serves as a wrapper to a pyserial object. It allows you to read lines without 100% CPU. It does not contain any timeout logic. If a timeout occurs, self.s.read(i) returns an empty string and you might want to throw an exception to indicate the timeout.

It is also supposed to be fast according to the author:

The code below gives me 790 kB/sec while replacing the code with pyserial's readline method gives me just 170kB/sec.

class ReadLine:
    def __init__(self, s):
        self.buf = bytearray()
        self.s = s

    def readline(self):
        i = self.buf.find(b"\n")
        if i >= 0:
            r = self.buf[:i+1]
            self.buf = self.buf[i+1:]
            return r
        while True:
            i = max(1, min(2048, self.s.in_waiting))
            data = self.s.read(i)
            i = data.find(b"\n")
            if i >= 0:
                r = self.buf + data[:i+1]
                self.buf[0:] = data[i+1:]
                return r
            else:
                self.buf.extend(data)

ser = serial.Serial('COM7', 9600)
rl = ReadLine(ser)

while True:

    print(rl.readline())

The command I am using most is C-] which jumps to the definition of the function under the cursor. You can use it more often to follow more calls. After that, C-o will bring you back one level, C-i goes deeper again.

If you encode the & in your URL to %26 it works correctly. Just tested and verified.

It work a simple example recursive (Y)

<?php 


function factorial($y,$x) { 

    if ($y < $x) { 
        echo $y; 
    } else { 
        echo $x; 
        factorial($y,$x+1);
    } 
}

$y=10;

$x=0;
factorial($y,$x);

 ?>

I've had success with this solution. It's almost like Patrick's, with a little twist. You can use these expressions separately or in sequence. If the parameter is blank, it will be ignored and all values for the column that your searching will be displayed, including NULLS.

SELECT * FROM MyTable
WHERE 
    --check to see if @param1 exists, if @param1 is blank, return all
    --records excluding filters below
(Col1 LIKE '%' + @param1 + '%' OR @param1 = '')
AND
    --where you want to search multiple columns using the same parameter
    --enclose the first 'OR' expression in braces and enclose the entire 
    --expression 
((Col2 LIKE '%' + @searchString + '%' OR Col3 LIKE '%' + @searchString + '%') OR @searchString = '')
AND
    --if your search requires a date you could do the following
(Cast(DateCol AS DATE) BETWEEN CAST(@dateParam AS Date) AND CAST(GETDATE() AS DATE) OR @dateParam = '')

Source size is not really a sensible thing to measure. For example, the following shell script:

cat foobar

is much shorter than either its Python or C++ equivalents.

1. Implement the Serializable interface when you want to be able to convert an instance of a class into a series of bytes or when you think that a Serializable object might reference an instance of your class.

2. Serializable classes are useful when you want to persist instances of them or send them over a wire.

3. Instances of Serializable classes can be easily transmitted. Serialization does have some security consequences, however. Read Joshua Bloch's Effective Java.

addition to the previous answer add file path directory for the write operation

 fs.writeFile(path.join(__dirname,jsonPath), JSON.stringify(newFileData), function (err) {}

As @Bruno suggested, using pytest fixtures is another solution that is accessible for both test classes or even just simple test functions. Here's an example testing python2.7 functions:

import pytest

@pytest.fixture(scope='function')
def some_resource(request):
    stuff_i_setup = ["I setup"]

    def some_teardown():
        stuff_i_setup[0] += " ... but now I'm torn down..."
        print stuff_i_setup[0]
    request.addfinalizer(some_teardown)

    return stuff_i_setup[0]

def test_1_that_needs_resource(some_resource):
    print some_resource + "... and now I'm testing things..."

So, running test_1... produces:

I setup... and now I'm testing things...
I setup ... but now I'm torn down...

Notice that stuff_i_setup is referenced in the fixture, allowing that object to be setup and torn down for the test it's interacting with. You can imagine this could be useful for a persistent object, such as a hypothetical database or some connection, that must be cleared before each test runs to keep them isolated.

How about:

firstNonNull = FluentIterable.from(
    Lists.newArrayList( a, b, c, ... ) )
        .firstMatch( Predicates.notNull() )
            .or( someKnownNonNullDefault );

Java ArrayList conveniently allows null entries and this expression is consistent regardless of the number of objects to be considered. (In this form, all the objects considered need to be of the same type.)

Use GA 'set' to ensure routes are picked up for Google realtime analytics. Otherwise subsequent calls to GA will not show in the realtime panel.

$scope.$on('$routeChangeSuccess', function() {
    $window.ga('set', 'page', $location.url());
    $window.ga('send', 'pageview');
});

Google strongly advises this approach generally instead of passing a 3rd param in 'send'. https://developers.google.com/analytics/devguides/collection/analyticsjs/single-page-applications

min(df['some_property'])
max(df['some_property'])

The built-in functions work well with Pandas Dataframes.

$("#id").change(function(){
    //does some stuff;
});

Starting with Python 3, raw_input() was renamed to input().

I can give a small hack, you can use T-SQL function. Try this:

SELECT ID, PARSENAME(WebsiteName, 2)
FROM dbo.YourTable .....

To complete Sandy Chapman's answer, here is a solution in Objective-C (put this category anywhere you want to change UILabel Appearance):

@implementation UILabel (FontOverride)
- (void)setSubstituteFontName:(NSString *)name UI_APPEARANCE_SELECTOR {
    self.font = [UIFont fontWithName:name size:self.font.pointSize];
}
@end

The interface file, should have this method declared publicly to be used later from places like your app delegate:

@interface UILabel (FontOverride)
  - (void)setSubstituteFontName:(NSString *)name UI_APPEARANCE_SELECTOR;
@end

Then, you can change the Appearance with:

[[UILabel appearance] setSubstituteFontName:@"SourceSansPro-Light"];

I came up with the following which takes account of rubbish passed in and file_get_contents failing....

function get_lonlat(  $addr  ) {
    try {
            $coordinates = @file_get_contents('http://maps.googleapis.com/maps/api/geocode/json?address=' . urlencode($addr) . '&sensor=true');
            $e=json_decode($coordinates);
            // call to google api failed so has ZERO_RESULTS -- i.e. rubbish address...
            if ( isset($e->status)) { if ( $e->status == 'ZERO_RESULTS' ) {echo '1:'; $err_res=true; } else {echo '2:'; $err_res=false; } } else { echo '3:'; $err_res=false; }
            // $coordinates is false if file_get_contents has failed so create a blank array with Longitude/Latitude.
            if ( $coordinates == false   ||  $err_res ==  true  ) {
                $a = array( 'lat'=>0,'lng'=>0);
                $coordinates  = new stdClass();
                foreach (  $a  as $key => $value)
                {
                    $coordinates->$key = $value;
                }
            } else {
                // call to google ok so just return longitude/latitude.
                $coordinates = $e;

                $coordinates  =  $coordinates->results[0]->geometry->location;
            }

            return $coordinates;
    }
    catch (Exception $e) {
    }

then to get the cords: where $pc is the postcode or address.... $address = get_lonlat( $pc ); $l1 = $address->lat; $l2 = $address->lng;

After executing the below regex, your answer is in the first capture.

/^(.*?)\.txt/

$property_images = $_FILES['property_images']['name'];
    if(!empty($property_images))
    {
        for($up=0;$up<count($property_images);$up++)
        {
            move_uploaded_file($_FILES['property_images']['tmp_name'][$up],'../images/property_images/'.$_FILES['property_images']['name'][$up]);
        }
    }

Just simply right A

{{ date('h:i A', strtotime($varname->created_at))}}

Use boost::hash

#include <boost\functional\hash.hpp>

...

std::string a = "ABCDE";
size_t b = boost::hash_value(a);

You can use exceptional handling as str.digit will only work for integers and can fail for something like this too:

>>> str.isdigit(' 1')
False

Using a generator function:

def solve(lis):                                        
    for x in lis:
        try:
            yield float(x)
        except ValueError:    
            pass

>>> mylist = ['1','orange','2','3','4','apple', '1.5', '2.6']
>>> list(solve(mylist))                                    
[1.0, 2.0, 3.0, 4.0, 1.5, 2.6]   #returns converted values

or may be you wanted this:

def solve(lis):
    for x in lis:
        try:
            float(x)
            return True
        except:
            return False
...         
>>> mylist = ['1','orange','2','3','4','apple', '1.5', '2.6']
>>> [x for x in mylist if solve(x)]
['1', '2', '3', '4', '1.5', '2.6']

or using ast.literal_eval, this will work for all types of numbers:

>>> from ast import literal_eval
>>> def solve(lis):
    for x in lis:
        try:
            literal_eval(x)
            return True
        except ValueError:   
             return False
...         
>>> mylist=['1','orange','2','3','4','apple', '1.5', '2.6', '1+0j']
>>> [x for x in mylist if solve(x)]                               
['1', '2', '3', '4', '1.5', '2.6', '1+0j']

I found the solution! Just copy the sheet with your named variables. Then delete the original sheet. The copied sheet will now have the same named variables, but with a local scope (scope= the copied sheet).

However, I don't know how to change from local variables to global..

Have a look at the Requests exception docs. In short:

In the event of a network problem (e.g. DNS failure, refused connection, etc), Requests will raise a ConnectionError exception.

In the event of the rare invalid HTTP response, Requests will raise an HTTPError exception.

If a request times out, a Timeout exception is raised.

If a request exceeds the configured number of maximum redirections, a TooManyRedirects exception is raised.

All exceptions that Requests explicitly raises inherit from requests.exceptions.RequestException.

To answer your question, what you show will not cover all of your bases. You'll only catch connection-related errors, not ones that time out.

What to do when you catch the exception is really up to the design of your script/program. Is it acceptable to exit? Can you go on and try again? If the error is catastrophic and you can't go on, then yes, you may abort your program by raising SystemExit (a nice way to both print an error and call sys.exit).

You can either catch the base-class exception, which will handle all cases:

try:
    r = requests.get(url, params={'s': thing})
except requests.exceptions.RequestException as e:  # This is the correct syntax
    raise SystemExit(e)

Or you can catch them separately and do different things.

try:
    r = requests.get(url, params={'s': thing})
except requests.exceptions.Timeout:
    # Maybe set up for a retry, or continue in a retry loop
except requests.exceptions.TooManyRedirects:
    # Tell the user their URL was bad and try a different one
except requests.exceptions.RequestException as e:
    # catastrophic error. bail.
    raise SystemExit(e)

As Christian pointed out:

If you want http errors (e.g. 401 Unauthorized) to raise exceptions, you can call Response.raise_for_status. That will raise an HTTPError, if the response was an http error.

An example:

try:
    r = requests.get('http://www.google.com/nothere')
    r.raise_for_status()
except requests.exceptions.HTTPError as err:
    raise SystemExit(err)

Will print:

404 Client Error: Not Found for url: http://www.google.com/nothere

Try using reduce or inject.

[1, 2, 3].reduce([]) { |memo, i|
  if i % 2 == 0
    memo << i
  end

  memo
}

I agree with the accepted answer that we shouldn't map and compact, but not for the same reasons.

I feel deep inside that map then compact is equivalent to select then map. Consider: map is a one-to-one function. If you are mapping from some set of values, and you map, then you want one value in the output set for each value in the input set. If you are having to select before-hand, then you probably don't want a map on the set. If you are having to select afterwards (or compact) then you probably don't want a map on the set. In either case you are iterating twice over the entire set, when a reduce only needs to go once.

Also, in English, you are trying to "reduce a set of integers into a set of even integers".

-http-proxy can be set in eclipse this way:

1. Menu Window
2. Submenu Preferences
3. In Preferences Dialog Click Android in left part Click Launch Near Default Emulator Options: input ur -http-proxy

In .NET the struct and class declarations differentiate between reference types and value types.

When you pass round a reference type there is only one actually stored. All the code that accesses the instance is accessing the same one.

When you pass round a value type each one is a copy. All the code is working on its own copy.

This can be shown with an example:

struct MyStruct 
{
    string MyProperty { get; set; }
}

void ChangeMyStruct(MyStruct input) 
{ 
   input.MyProperty = "new value";
}

...

// Create value type
MyStruct testStruct = new MyStruct { MyProperty = "initial value" }; 

ChangeMyStruct(testStruct);

// Value of testStruct.MyProperty is still "initial value"
// - the method changed a new copy of the structure.

For a class this would be different

class MyClass 
{
    string MyProperty { get; set; }
}

void ChangeMyClass(MyClass input) 
{ 
   input.MyProperty = "new value";
}

...

// Create reference type
MyClass testClass = new MyClass { MyProperty = "initial value" };

ChangeMyClass(testClass);

// Value of testClass.MyProperty is now "new value" 
// - the method changed the instance passed.

Classes can be nothing - the reference can point to a null.

Structs are the actual value - they can be empty but never null. For this reason structs always have a default constructor with no parameters - they need a 'starting value'.

Thank you! I have recently converted to python 3 and have been frustrated by using readlines(0) to read large files. This solved the problem. But to get each line, I had to do a couple extra steps. Each line was preceded by a "b'" which I guess that it was in binary format. Using "decode(utf-8)" changed it ascii.

Then I had to remove a "=\n" in the middle of each line.

Then I split the lines at the new line.

b_data=(fh.read(ele[1]))#endat This is one chunk of ascii data in binary format
        a_data=((binascii.b2a_qp(b_data)).decode('utf-8')) #Data chunk in 'split' ascii format
        data_chunk = (a_data.replace('=\n','').strip()) #Splitting characters removed
        data_list = data_chunk.split('\n')  #List containing lines in chunk
        #print(data_list,'\n')
        #time.sleep(1)
        for j in range(len(data_list)): #iterate through data_list to get each item 
            i += 1
            line_of_data = data_list[j]
            print(line_of_data)

Here is the code starting just above "print data" in Arohi's code.

private static String getCurrentDateIso()
{
    // Returns the current date with the same format as Javascript's new Date().toJSON(), ISO 8601
    DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.US);
    dateFormat.setTimeZone(TimeZone.getTimeZone("UTC"));
    return dateFormat.format(new Date());
}

Surprising solution -
adding following property to the applied selectors:

selector {
    text-shadow: 0 0 0;
}

Actually, result is the same just with text-shadow: 0 0;, but I like to explicitly set blur-radius.

It's not an universal solution, but might help in some cases. Moreover I haven't experienced (also not thoroughly tested) negative performance impacts of this solution so far.

Digging StackOverflow for answers on the similar issue I found people usually suggesting 2 approaches:

• Load a drawable into memory and compare ConstantState or bitmap itself to other one.
• Set a tag with drawable id into a view and compare tags when you need that.

Personally, I like the second approach for performance reason but tagging bunch of views with appropriate tags is painful and time consuming. This could be very frustrating in a big project. In my case I need to write a lot of Espresso tests which require comparing TextView drawables, ImageView resources, View background and foreground. A lot of work.

So I eventually came up with a solution to delegate a 'dirty' work to the custom inflater. In every inflated view I search for a specific attributes and and set a tag to the view with a resource id if any is found. This approach is pretty much the same guys from Calligraphy used. I wrote a simple library for that: TagView

If you use it, you can retrieve any of predefined tags, containing drawable resource id that was set in xml layout file:

TagViewUtils.getTag(view, ViewTag.IMAGEVIEW_SRC.id)
TagViewUtils.getTag(view, ViewTag.TEXTVIEW_DRAWABLE_LEFT.id)
TagViewUtils.getTag(view, ViewTag.TEXTVIEW_DRAWABLE_TOP.id)
TagViewUtils.getTag(view, ViewTag.TEXTVIEW_DRAWABLE_RIGHT.id)
TagViewUtils.getTag(view, ViewTag.TEXTVIEW_DRAWABLE_BOTTOM.id)
TagViewUtils.getTag(view, ViewTag.VIEW_BACKGROUND.id)
TagViewUtils.getTag(view, ViewTag.VIEW_FOREGROUND.id)

The library supports any attribute, actually. You can add them manually, just look into the Custom attributes section on Github. If you set a drawable in runtime you can use convenient library methods:

setImageViewResource(ImageView view, int id)

In this case tagging is done for you internally. If you use Kotlin you can write a handy extensions to call view itself. Something like this:

fun ImageView.setImageResourceWithTag(@DrawableRes int id) {
    TagViewUtils.setImageViewResource(this, id)
}

You can find additional info in Tagging in runtime

Hi welcome to the world of R.

mtcars  #look at this built in data set
str(mtcars) #allows you to see the classes of the variables (all numeric)

#one approach it to index with the $ sign and the as.factor function
mtcars$am <- as.factor(mtcars$am)
#another approach
mtcars[, 'cyl'] <- as.factor(mtcars[, 'cyl'])
str(mtcars)  # now look at the classes

This also works for character, dates, integers and other classes

Since you're new to R I'd suggest you have a look at these two websites:

R reference manuals: http://cran.r-project.org/manuals.html

R Reference card: http://cran.r-project.org/doc/contrib/Short-refcard.pdf

Using jquery? I've used this before: http://projects.allmarkedup.com/jquery_url_parser/ and it worked pretty well.

Here's another way of doing the code above using the openpyxl module that's compatible with xlsx. From what I've seen so far, it also keeps formatting.

from openpyxl import load_workbook
wb = load_workbook('names.xlsx')
ws = wb['SheetName']
ws['A1'] = 'A1'
wb.save('names.xlsx')

From: jQuery text truncation (read more style)

Try this:

var title = "This is your title";

var shortText = jQuery.trim(title).substring(0, 10)
    .split(" ").slice(0, -1).join(" ") + "...";

• Tested here

And you can also use a plugin:

• jQuery Expander Plugin

As a extension of String

String.prototype.trimToLength = function(m) {
  return (this.length > m) 
    ? jQuery.trim(this).substring(0, m).split(" ").slice(0, -1).join(" ") + "..."
    : this;
};

Use as

"This is your title".trimToLength(10);

You can use the "Join" function to create a single string out of the array of labels, like this:

=Join(Parameters!Product.Label, ",")

Does:

Set Sheets("Output").Range("$A$1:$A$500") =  Sheets(sheet_).Range("$A$1:$A$500")

...work? (I don't have Excel in front of me, so can't test.)

_{All standard references below refers to N4659: March 2017 post-Kona working draft/C++17 DIS.}

Typedef declarations can, whereas alias declarations cannot, be used as initialization statements

But, with the first two non-template examples, are there any other subtle differences in the standard?

• Differences in semantics: none.
• Differences in allowed contexts: some⁽¹⁾.

^{(1) In addition to the examples of alias templates, which has already been mentioned in the original post.}

Same semantics

As governed by [dcl.typedef]/2 [extract, emphasis mine]

[dcl.typedef]/2 A typedef-name can also be introduced by an alias-declaration. The identifier following the using keyword becomes a typedef-name and the optional attribute-specifier-seq following the identifier appertains to that typedef-name. Such a typedef-name has the same semantics as if it were introduced by the typedef specifier. [...]

a typedef-name introduced by an alias-declaration has the same semantics as if it were introduced by the typedef declaration.

Subtle difference in allowed contexts

However, this does not imply that the two variations have the same restrictions with regard to the contexts in which they may be used. And indeed, albeit a corner case, a typedef declaration is an init-statement and may thus be used in contexts which allow initialization statements

// C++11 (C++03) (init. statement in for loop iteration statements).
for(typedef int Foo; Foo{} != 0;) {}

// C++17 (if and switch initialization statements).
if (typedef int Foo; true) { (void)Foo{}; }
//  ^^^^^^^^^^^^^^^ init-statement

switch(typedef int Foo; 0) { case 0: (void)Foo{}; }
//     ^^^^^^^^^^^^^^^ init-statement

// C++20 (range-based for loop initialization statements).
std::vector<int> v{1, 2, 3};
for(typedef int Foo; Foo f : v) { (void)f; }
//  ^^^^^^^^^^^^^^^ init-statement

for(typedef struct { int x; int y;} P;
//  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ init-statement
    auto [x, y] : {P{1, 1}, {1, 2}, {3, 5}}) { (void)x; (void)y; }

whereas an alias-declaration is not an init-statement, and thus may not be used in contexts which allows initialization statements

// C++ 11.
for(using Foo = int; Foo{} != 0;) {}
//  ^^^^^^^^^^^^^^^ error: expected expression

// C++17 (initialization expressions in switch and if statements).
if (using Foo = int; true) { (void)Foo{}; }
//  ^^^^^^^^^^^^^^^ error: expected expression

switch(using Foo = int; 0) { case 0: (void)Foo{}; }
//     ^^^^^^^^^^^^^^^ error: expected expression

// C++20 (range-based for loop initialization statements).
std::vector<int> v{1, 2, 3};
for(using Foo = int; Foo f : v) { (void)f; }
//  ^^^^^^^^^^^^^^^ error: expected expression

One thing you should be aware of when using each is that it has the side effect of adding "state" to your hash (the hash has to remember what the "next" key is). When using code like the snippets posted above, which iterate over the whole hash in one go, this is usually not a problem. However, you will run into hard to track down problems (I speak from experience ;), when using each together with statements like last or return to exit from the while ... each loop before you have processed all keys.

In this case, the hash will remember which keys it has already returned, and when you use each on it the next time (maybe in a totaly unrelated piece of code), it will continue at this position.

Example:

my %hash = ( foo => 1, bar => 2, baz => 3, quux => 4 );

# find key 'baz'
while ( my ($k, $v) = each %hash ) {
    print "found key $k\n";
    last if $k eq 'baz'; # found it!
}

# later ...

print "the hash contains:\n";

# iterate over all keys:
while ( my ($k, $v) = each %hash ) {
    print "$k => $v\n";
}

This prints:

found key bar
found key baz
the hash contains:
quux => 4
foo => 1

What happened to keys "bar" and baz"? They're still there, but the second each starts where the first one left off, and stops when it reaches the end of the hash, so we never see them in the second loop.

I normally use this class for my work. It's pretty good.

For version 5:

If you downloaded the free package from this site:

https://fontawesome.com/download

The fonts are in the all.css and all.min.css file.

So your reference will look something like this:

<link href="/MyProject/Content/fontawesome-free-5.10.1-web/css/all.min.css" rel="stylesheet">

The fontawesome.css file does not include the font reference.

A sample - write multiple rows with boolean column (using example above by GaretJax and Eran?).

import csv
RESULT = [['IsBerry','FruitName'],
          [False,'apple'],
          [True, 'cherry'],
          [False,'orange'],
          [False,'pineapple'],
          [True, 'strawberry']]
with open("../datasets/dashdb.csv", 'wb') as resultFile:
    wr = csv.writer(resultFile, dialect='excel')
    wr.writerows(RESULT)

Result:

df_data_4 = pd.read_csv('../datasets/dashdb.csv')
df_data_4.head()

Output:

   IsBerry  FruitName
   0    False   apple
   1    True    cherry
   2    False   orange
   3    False   pineapple
   4    True    strawberry

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

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

and in your component file

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

Hope I can help you.

You can use .replaceWith()

$(function() {_x000D_
_x000D_
  $(".region").click(function(e) {_x000D_
    e.preventDefault();_x000D_
    var content = $(this).html();_x000D_
    $('#map').replaceWith('<div class="region">' + content + '</div>');_x000D_
  });_x000D_
_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<div id="map">_x000D_
  <div class="region"><a href="link1">region1</a></div>_x000D_
  <div class="region"><a href="link2">region2</a></div>_x000D_
  <div class="region"><a href="link3">region3</a></div>_x000D_
</div>

<%# (string)Eval("gender") =="M" ? "Male" :"Female"%>

If you use setState inside componentDidUpdate it updates the component, resulting in a call to componentDidUpdate which subsequently calls setState again resulting in the infinite loop. You should conditionally call setState and ensure that the condition violating the call occurs eventually e.g:

componentDidUpdate: function() {
    if (condition) {
        this.setState({..})
    } else {
        //do something else
    }
}

In case you are only updating the component by sending props to it(it is not being updated by setState, except for the case inside componentDidUpdate), you can call setState inside componentWillReceiveProps instead of componentDidUpdate.

You can use

sessionStorage.SessionName = "SessionData" ,

sessionStorage.getItem("SessionName") and

sessionStorage.setItem("SessionName","SessionData");

See the supported browsers on http://caniuse.com/namevalue-storage

The simplest way to do this is through Visual Studio's object explorer, which is also supported in the Community edition.

Once you have made a connection to SQL server, browse to the type, right click and select View Code, make your changes to the schema of the user defined type and click update. Visual Studio should show you all of the dependencies for that object and generate scripts to update the type and recompile dependencies.

Makefile.am is a programmer-defined file and is used by automake to generate the Makefile.in file (the .am stands for automake). The configure script typically seen in source tarballs will use the Makefile.in to generate a Makefile.

The configure script itself is generated from a programmer-defined file named either configure.ac or configure.in (deprecated). I prefer .ac (for autoconf) since it differentiates it from the generated Makefile.in files and that way I can have rules such as make dist-clean which runs rm -f *.in. Since it is a generated file, it is not typically stored in a revision system such as Git, SVN, Mercurial or CVS, rather the .ac file would be.

Read more on GNU Autotools. Read about make and Makefile first, then learn about automake, autoconf, libtool, etc.

You don't need javascript for doing so. Just delete the onClick and write the php Admin.php file like this:

<!-- HTML STARTS-->
<?php
//If all the required fields are filled
if (!empty($GET_['fullname'])&&!empty($GET_['email'])&&!empty($GET_['name']))
{
function addNewContact()
    {
    $new = '{';
    $new .= '"fullname":"' . $_GET['fullname'] . '",';
    $new .= '"email":"' . $_GET['email'] . '",';
    $new .= '"phone":"' . $_GET['phone'] . '",';
    $new .= '}';
    return $new;
    }

function saveContact()
    {
    $datafile = fopen ("data/data.json", "a+");
    if(!$datafile){
        echo "<script>alert('Data not existed!')</script>";
        } 
    else{
        $contact_list = $contact_list . addNewContact();
        file_put_contents("data/data.json", $contact_list);
        }
    fclose($datafile);
    }

// Call the function saveContact()
saveContact();
echo "Thank you for joining us";
}
else //If the form is not submited or not all the required fields are filled

{ ?>

<form>
    <fieldset>
        <legend>Add New Contact</legend>
        <input type="text" name="fullname" placeholder="First name and last name" required /> <br />
        <input type="email" name="email" placeholder="[email protected]" required /> <br />
        <input type="text" name="phone" placeholder="Personal phone number: mobile, home phone etc." required /> <br />
        <input type="submit" name="submit" class="button" value="Add Contact"/>
        <input type="button" name="cancel" class="button" value="Reset" />
    </fieldset>
</form>
<?php }
?>
<!-- HTML ENDS -->

Thought I don't like the PHP bit. Do you REALLY want to create a file for contacts? It'd be MUCH better to use a mysql database. Also, adding some breaks to that file would be nice too...

Other thought, IE doesn't support placeholder.

Small correction for the Set-Content command. If the searched string is not found the Set-Content command will blank (empty) the target file.

You can first verify if the string you are looking for exist or not. If not it will not replace anything.

If (select-string -path "c:\Windows\System32\drivers\etc\hosts" -pattern "String to look for") `
    {(Get-Content c:\Windows\System32\drivers\etc\hosts).replace('String to look for', 'String to replace with') | Set-Content c:\Windows\System32\drivers\etc\hosts}
    Else{"Nothing happened"}

You can use noConflict function:

var JJ= jQuery.noConflict(); 
JJ('.back').click(function (){
    window.history.back();
}); 

Change all $ to JJ.

Creating a .bashrc file in your home directory also works. That way you don't have to copy your .bash_profile every time you install a new version of git bash.

This is possible with <textarea> the only thing you need to do is use Summernote WYSIWYG editor

it interprets HTML tags inside a textarea (namely <strong>, <i>, <u>, <a>)

Internally, getters and setters are just methods. When C# compiles, it generates methods for your getters and setters like this, for example:

public int get_MyProperty() { ... }
public void set_MyProperty(int value) { ... }

C# allows you to declare these methods using a short-hand syntax. The line below will be compiled into the methods above when you build your application.

public int MyProperty { get; set; }

or

private int myProperty;
public int MyProperty 
{ 
    get { return myProperty; }
    set { myProperty = value; } // value is an implicit parameter containing the value being assigned to the property.
}

I hope this would be helpful:

.top_image img{
display: block;
margin: 0 auto;
}

Pipe a command to stdin

Must remove the -t for it to work:

echo 'touch myfile' | sudo docker exec -i CONTAINER_NAME bash

This can be more convenient that using CLI options sometimes.

Tested with:

sudo docker run --name ub16 -it ubuntu:16.04 bash

then on another shell:

echo 'touch myfile' | sudo docker exec -i ub16 bash

Then on first shell:

ls -l myfile

Tested on Docker 1.13.1, Ubuntu 16.04 host.

First give or check permissions like

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

If these two permissions are OK, then check your output streams are in correct format.

Example:

FileOutputStream fos=new FileOutputStream(Environment.getExternalStorageDirectory()+"/rahul1.jpg");

Chengs's answer is correct, howewer according to the admin docs not every admin template can be overwritten this way: https://docs.djangoproject.com/en/1.9/ref/contrib/admin/#overriding-admin-templates

Templates which may be overridden per app or model

Not every template in contrib/admin/templates/admin may be overridden per app or per model. The following can:

app_index.html
change_form.html
change_list.html
delete_confirmation.html
object_history.html

For those templates that cannot be overridden in this way, you may still override them for your entire project. Just place the new version in your templates/admin directory. This is particularly useful to create custom 404 and 500 pages

I had to overwrite the login.html of the admin and therefore had to put the overwritten template in this folder structure:

your_project
 |-- your_project/
 |-- myapp/

(without the myapp subfolder in the admin) I do not have enough repution for commenting on Cheng's post this is why I had to write this as new answer.

An all-pairs shortest path algorithm will compute the shortest paths between all vertices in a graph. This will allow paths to be pre-computed instead of requiring a path to be calculated each time someone wants to find the shortest path between a source and a destination. The Floyd-Warshall algorithm is an all-pairs shortest path algorithm.

First off, if subversion installed on your machine? if not look at what server your tortoisesvn is setup to connect to.

the default location when subversion is installed is c:\program files\subversion you can find svn.exe in c:\program files\subversion\bin where you can run your cmd line actions.

<body>
<table>
<tr><td colspan="2" rowspan="2">1</td><td colspan="4">2</td></tr>
<tr><td>3</td><td>3</td><td>3</td><td>3</td></tr>
<tr><td colspan="2">1</td><td>3</td><td>3</td><td>3</td><td>3</td></tr>
</table>
</body>

Unfortunately, no. Not with HTML and CSS. You need an a element to make a link, and you can't wrap an entire table row in one.

The closest you can get is linking every table cell. Personally I'd just link one cell and use JavaScript to make the rest clickable. It's good to have at least one cell that really looks like a link, underlined and all, for clarity anyways.

Here's a simple jQuery snippet to make all table rows with links clickable (it looks for the first link and "clicks" it)

$("table").on("click", "tr", function(e) {
    if ($(e.target).is("a,input")) // anything else you don't want to trigger the click
        return;

    location.href = $(this).find("a").attr("href");
});

Not sure if this is faster, but at least it's shorter :)

int rows = new DataView(dtFoo, "IsActive = 'Y'", "IsActive",
    DataViewRowState.CurrentRows).Table.Rows.Count;

Here is a simple example, all it does is overlay an image (with whatever wording you want). I saw this technique somewhere. I am using the prototype library so you would need to modify if using something else. With the image loading after window.load it fails gracefully if javascript is disabled.

That is because you are posting data through a get method.

Instead of

Route::get('/validate', 'MemberController@validateCredentials');

Try this

Route::post('/validate', 'MemberController@validateCredentials');

Building on top of the Mozdev post that natevw references I've started a small project to render HTML to canvas in Firefox, Chrome & Safari. So for example you can simply do:

rasterizeHTML.drawHTML('<span class="color: green">This is HTML</span>' 
                     + '<img src="local_img.png"/>', canvas);

Source code and a more extensive example is here.

As the creator of ElasticSearch, maybe I can give you some reasoning on why I went ahead and created it in the first place :).

Using pure Lucene is challenging. There are many things that you need to take care for if you want it to really perform well, and also, its a library, so no distributed support, it's just an embedded Java library that you need to maintain.

In terms of Lucene usability, way back when (almost 6 years now), I created Compass. Its aim was to simplify using Lucene and make everyday Lucene simpler. What I came across time and time again is the requirement to be able to have Compass distributed. I started to work on it from within Compass, by integrating with data grid solutions like GigaSpaces, Coherence, and Terracotta, but it's not enough.

At its core, a distributed Lucene solution needs to be sharded. Also, with the advancement of HTTP and JSON as ubiquitous APIs, it means that a solution that many different systems with different languages can easily be used.

This is why I went ahead and created ElasticSearch. It has a very advanced distributed model, speaks JSON natively, and exposes many advanced search features, all seamlessly expressed through JSON DSL.

Solr is also a solution for exposing an indexing/search server over HTTP, but I would argue that ElasticSearch provides a much superior distributed model and ease of use (though currently lacking on some of the search features, but not for long, and in any case, the plan is to get all Compass features into ElasticSearch). Of course, I am biased, since I created ElasticSearch, so you might need to check for yourself.

As for Sphinx, I have not used it, so I can't comment. What I can refer you is to this thread at Sphinx forum which I think proves the superior distributed model of ElasticSearch.

Of course, ElasticSearch has many more features than just being distributed. It is actually built with a cloud in mind. You can check the feature list on the site.

Solution

mylist = [1, 6, 7, 8, 1, 10, 15, 9]
print(mylist)
n = len(mylist)
for i in range(n):
    for j in range(1, n-i):
        if mylist[j-1] > mylist[j]:
             (mylist[j-1], mylist[j]) = (mylist[j], mylist[j-1])
print(mylist)

How about getSelectedDate? Anyway, specifically on your code question, the problem is with this line:

new SimpleDateFormat("yyyy-MM-dd");

The string that goes in the constructor has to match the format of the date. The documentation for how to do that is here. Looks like you need something close to "EEE MMM d HH:mm:ss zzz yyyy"

git merge origin/master instead git merge master worked for me. So to merge master into feature branch you may use:

git checkout feature_branch
git merge origin/master

You have to be careful with what you want to do, because it is not just about to get the time.

The batch has internal variables to represent the date and the tme: %DATE% %TIME%. But they dependent on the Windows Locale.

%Date%:

• dd.MM.yyyy
• dd.MM.yy
• d.M.yy
• dd/MM/yy
• yyyy-MM-dd

%TIME%:

• H:mm:ss,msec
• HH:mm:ss,msec

Now, how long your script will work and when? For example, if it will be longer than a day and does pass the midnight it will definitely goes wrong, because difference between 2 timestamps between a midnight is a negative value! You need the date to find out correct distance between days, but how you do that if the date format is not a constant? Things with %DATE% and %TIME% might goes worser and worser if you continue to use them for the math purposes.

The reason is the %DATE% and %TIME% are exist is only to show a date and a time to user in the output, not to use them for calculations. So if you want to make correct distance between some time values or generate some unique value dependent on date and time then you have to use something different and accurate than %DATE% and %TIME%.

I am using the wmic windows builtin utility to request such things (put it in a script file):

for /F "usebackq tokens=1,2 delims==" %%i in (`wmic os get LocalDateTime /VALUE`) do if "%%i" == "LocalDateTime" echo.%%j

or type it in the cmd.exe console:

for /F "usebackq tokens=1,2 delims==" %i in (`wmic os get LocalDateTime /VALUE`) do @if "%i" == "LocalDateTime" echo.%j

The disadvantage of this is a slow performance in case of frequent calls. On mine machine it is about 12 calls per second.

If you want to continue use this then you can write something like this (get_datetime.bat):

@echo off

rem Description:
rem   Independent to Windows locale date/time request.

rem Drop last error level
cd .

rem drop return value
set "RETURN_VALUE="

for /F "usebackq tokens=1,2 delims==" %%i in (`wmic os get LocalDateTime /VALUE 2^>NUL`) do if "%%i" == "LocalDateTime" set "RETURN_VALUE=%%j"

if not "%RETURN_VALUE%" == "" (
  set "RETURN_VALUE=%RETURN_VALUE:~0,18%"
  exit /b 0
)

exit /b 1

Now, you can parse %RETURN_VALUE% somethere in your script:

call get_datetime.bat
set "FILE_SUFFIX=%RETURN_VALUE:.=_%"
set "FILE_SUFFIX=%FILE_SUFFIX:~8,2%_%FILE_SUFFIX:~10,2%_%FILE_SUFFIX:~12,6%"
echo.%FILE_SUFFIX%

This query works for me:

SELECT DISTINCT 
    local_tcp_port 
FROM sys.dm_exec_connections 
WHERE local_tcp_port IS NOT NULL 

Answering the question in your title, you can query sys.tables or sys.objects where type = 'U' to check for the existence of a table. You can also use OBJECT_ID('table_name', 'U'). If it returns a non-null value then the table exists:

IF (OBJECT_ID('dbo.My_Table', 'U') IS NULL)
BEGIN
    CREATE TABLE dbo.My_Table (...)
END

You can do the same for databases with DB_ID():

IF (DB_ID('My_Database') IS NULL)
BEGIN
    CREATE DATABASE My_Database
END

If you want to create the database and then start using it, that needs to be done in separate batches. I don't know the specifics of your case, but there shouldn't be many cases where this isn't possible. In a SQL script you can use GO statements. In an application it's easy enough to send across a new command after the database is created.

The only place that you might have an issue is if you were trying to do this in a stored procedure and creating databases on the fly like that is usually a bad idea.

If you really need to do this in one batch, you can get around the issue by using EXEC to get around the parsing error of the database not existing:

CREATE DATABASE Test_DB2

IF (OBJECT_ID('Test_DB2.dbo.My_Table', 'U') IS NULL)
BEGIN
    EXEC('CREATE TABLE Test_DB2.dbo.My_Table (my_id INT)')
END

EDIT: As others have suggested, the INFORMATION_SCHEMA.TABLES system view is probably preferable since it is supposedly a standard going forward and possibly between RDBMSs.

try:
    if val is None: # The variable
        print('It is None')
except NameError:
    print ("This variable is not defined")
else:
    print ("It is defined and has a value")

Built upon rsplak's answer. It uses jQuery's newer .on() instead of the deprecated .bind(). In addition to input, it will also work for select and other html elements. It will also disable the submit button if one of the fields becomes blank again.

var fields = "#user_input, #pass_input, #v_pass_input, #email";

$(fields).on('change', function() {
    if (allFilled()) {
        $('#register').removeAttr('disabled');
    } else {
        $('#register').attr('disabled', 'disabled');
    }
});

function allFilled() {
    var filled = true;
    $(fields).each(function() {
        if ($(this).val() == '') {
            filled = false;
        }
    });
    return filled;
}

Demo: JSFiddle

Although I would personally use a with statement to handle opening and closing a file, in the case where you have to read from stdin and need to track an EOF exception, do something like this:

Use a try-catch with EOFError as the exception:

try:
    input_lines = ''
    for line in sys.stdin.readlines():
        input_lines += line             
except EOFError as e:
    print e

Please see https://github.com/joshua-gould/canvas2pdf. This library creates a PDF representation of your canvas element, unlike the other proposed solutions which embed an image in a PDF document.

//Create a new PDF canvas context.
var ctx = new canvas2pdf.Context(blobStream());

//draw your canvas like you would normally
ctx.fillStyle='yellow';
ctx.fillRect(100,100,100,100);
// more canvas drawing, etc...

//convert your PDF to a Blob and save to file
ctx.stream.on('finish', function () {
    var blob = ctx.stream.toBlob('application/pdf');
    saveAs(blob, 'example.pdf', true);
});
ctx.end();

It works better

CREATE TABLE [dbo].[T_Status](
   [Status] [nvarchar](20) NULL
) ON [PRIMARY]

GO
INSERT [dbo].[T_Status] ([Status]) VALUES (N'Active')
GO
INSERT [dbo].[T_Status] ([Status]) VALUES (N'notActive')
GO
INSERT [dbo].[T_Status] ([Status]) VALUES (N'Active')
GO

DECLARE @GetStatus nvarchar(20) = null
--DECLARE @GetStatus nvarchar(20) = 'Active'
SELECT [Status]
FROM [T_Status]
WHERE  [Status] = CASE WHEN (isnull(@GetStatus, '')='') THEN [Status]
ELSE @GetStatus END

If you are running python 3 then you need to change the print statements to print functions, i.e. put things in brackets () after print statements.

The only thing that you will see the above do is the prints unless you have something listening on 127.0.0.1 port 5005 as you are sending a packet not receiving it - so you need to implement and start the other part of the example in another console window first so it is waiting for the message.

If you have to wait there is a method presenceOfNestedElementLocatedBy that takes the "parent" element and a locator, e.g. a By.xpath:

WebElement subNode = new WebDriverWait(driver,10).until(
    ExpectedConditions.presenceOfNestedElementLocatedBy(
        divA, By.xpath(".//div/span")
    )
);

You can use following css to make an element middle aligned styled with position: absolute:

.element {
  transform: translateX(-50%);
  position: absolute;
  left: 50%;
}

With CSS having only left: 50% we will have following effect:

While combining left: 50% with transform: translate(-50%) we will have following:

.hero {  _x000D_
  background-color: #e15915;_x000D_
  position: relative;_x000D_
  height: 320px;_x000D_
  width: 100%;_x000D_
}_x000D_
_x000D_
_x000D_
.hero:after {_x000D_
  border-right: solid 50px transparent;_x000D_
  border-left: solid 50px transparent;_x000D_
  border-top: solid 50px #e15915;_x000D_
  transform: translateX(-50%);_x000D_
  position: absolute;_x000D_
  z-index: -1;_x000D_
  content: '';_x000D_
  top: 100%;_x000D_
  left: 50%;_x000D_
  height: 0;_x000D_
  width: 0;_x000D_
}

<div class="hero">_x000D_
_x000D_
</div>

I removed the bugs in above code and got below results: Also I am unsure given how NetSerializer requires you to register the types you are serializing, what kind of compatibility or performance differences that could potentially make.

        $firstWord = strstr($title," ",true);
        $remainingTitle = substr(strstr($title," "), 1);

        if( !empty( $firstWord ) ) {
            $return['first'] = $firstWord;
        }
        if( !empty( $remainingTitle ) ) {
            $return['remaining'] = $remainingTitle;
        }
    }
    else {
        $return['first'] = $title;
    }

    return $return;
}

Raising ActionController::RoutingError('not found') has always felt a little bit strange to me - in the case of an unauthenticated user, this error does not reflect reality - the route was found, the user is just not authenticated.

I happened across config.action_dispatch.rescue_responses and I think in some cases this is a more elegant solution to the stated problem:

# application.rb
config.action_dispatch.rescue_responses = {
  'UnauthenticatedError' => :not_found
}

# my_controller.rb
before_action :verify_user_authentication

def verify_user_authentication
  raise UnauthenticatedError if !user_authenticated?
end

What's nice about this approach is:

1. It hooks into the existing error handling middleware like a normal ActionController::RoutingError, but you get a more meaningful error message in dev environments
2. It will correctly set the status to whatever you specify in the rescue_responses hash (in this case 404 - not_found)
3. You don't have to write a not_found method that needs to be available everywhere.

Add height & width properties to your .css file.

If there are NO dependencies between files... here is a recursive function to include_once ALL php files in ALL subdirs:

$paths = array();

function include_recursive( $path, $debug=false){
  foreach( glob( "$path/*") as $filename){        
    if( strpos( $filename, '.php') !== FALSE){ 
       # php files:
       include_once $filename;
       if( $debug) echo "<!-- included: $filename -->\n";
    } else { # dirs
       $paths[] = $filename; 
    }
  }
  # Time to process the dirs:
  for( $i=count($paths)-1; $i>0; $i--){
    $path = $paths[$i];
    unset( $paths[$i]);
    include_recursive( $path);
  }
}

include_recursive( "tree_to_include");
# or... to view debug in page source:
include_recursive( "tree_to_include", 'debug');

You can also use meta-annotations to externalize the configuration. For example:

@RunWith(SpringJUnit4ClassRunner.class)
@DefaultTestAnnotations
public class ExampleApplicationTests { 
   ...
}

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
@SpringApplicationConfiguration(classes = ExampleApplication.class)
@TestPropertySource(locations="classpath:test.properties")
public @interface DefaultTestAnnotations { }

just run below command

PORT=3001 npm start

#include <iostream>
#include <fstream>
using namespace std;

void main()
{
    ifstream in_stream; // fstream command to initiate "in_stream" as a command.
    char filename[31]; // variable for "filename".
    cout << "Enter file name to open :: "; // asks user for input for "filename".
    cin.getline(filename, 30); // this gets the line from input for "filename".
    in_stream.open(filename); // this in_stream (fstream) the "filename" to open.
    if (in_stream.fail())
    {
        cout << "Could not open file to read.""\n"; // if the open file fails.
        return;
    }
    //.....the rest of the text goes beneath......
}

I am assuming you want to display this as part of the player.

This site breaks down how to get both the current and total time regardless of how you want to display it though using jQuery:

http://dev.opera.com/articles/view/custom-html5-video-player-with-css3-and-jquery/

This will also cover how to set it to a specific div. As philip has already mentioned, .currentTime will give you where you are in the video.

Timezones and stuff aside, a very simple alternative to new Date(startDateLong) could be LocalDate.ofEpochDay(startDateLong / 86400000L)

More universal can be: for each v Selection : v.value = "'" & v.value : next and selecting range of cells before execution

In my case it works with a little change. Simply by putting :$PATH at the end.

# andorid paths
export ANDROID_HOME=$HOME/Android/Sdk
export PATH="$ANDROID_HOME/tools:$PATH"
export PATH="$ANDROID_HOME/platform-tools:$PATH"
export PATH="$ANDROID_HOME/emulator:$PATH"

When signing into the server to execute the code use this instead:

ssh -X username@servername

the -X will get rid of the no display name and no $DISPLAY environment variable error

:)

I have created on time task in which the task which user wants to repeat, add in the Custom TimeTask run() method. it is successfully reoccurring.

First make sure the PHP files themselves are UTF-8 encoded.

The meta tag is ignored by some browser. If you only use ASCII-characters, it doesn't matter anyway.

http://en.wikipedia.org/wiki/List_of_HTTP_header_fields

header('Content-Type: text/html; charset=utf-8');

If you don't want to use a function constructor like in Brian's answer you can use Object.create() instead:-

var myVar = {
count: 0
}

myVar.init = function(n) {
    this.count = n
    this.newDiv()
}

myVar.newDiv = function() {
    var newDiv = document.createElement("div")
    var contents = document.createTextNode("Click me!")
    var func = myVar.func(this)
    newDiv.addEventListener ? 
        newDiv.addEventListener('click', func, false) : 
        newDiv.attachEvent('onclick', func)
    newDiv.appendChild(contents)
    document.getElementsByTagName("body")[0].appendChild(newDiv)
}

myVar.func = function (thys) {
   return function() {
      thys.clickme()
   }
} 

myVar.clickme = function () {
   this.count += 1
   alert(this.count)
}

myVar.init(2)

var myVar1 = Object.create(myVar)
myVar1.init(55) 

var myVar2 = Object.create(myVar)
myVar2.init(150) 

// etc

Strangely, I couldn't get the above to work using newDiv.onClick, but it works with newDiv.addEventListener / newDiv.attachEvent.

Since Object.create is newish, include the following code from Douglas Crockford for older browsers, including IE8.

if (typeof Object.create !== 'function') {
    Object.create = function (o) {
        function F() {}
        F.prototype = o
        return new F()
    }
}

Use LISTAGG function, ex. SELECT LISTAGG(colmn) FROM table_name;

Here is the official explanation: https://github.com/golang/go/wiki/InterfaceSlice

var dataSlice []int = foo()
var interfaceSlice []interface{} = make([]interface{}, len(dataSlice))
for i, d := range dataSlice {
    interfaceSlice[i] = d
}

From the simulator, in iPad mode:

Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_5_8; en-us) AppleWebKit/531.9 (KHTML, like Gecko) Version/4.0.3 Safari/531.9 _{(this is for 3.2 beta 1)}

Mozilla/5.0 (iPad; U; CPU OS 3_2 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Version/4.0.4 Mobile/7B334b Safari/531.21.10 _{(this is for 3.2 beta 3)}

and in iPhone mode:

Mozilla/5.0 (iPhone; U; CPU iPhone OS 3_2 like Mac OS X; en-us) AppleWebKit/531.21.20 (KHTML, like Gecko) Mobile/7B298g

I don't know how reliable the simulator is, but it seems you can't detect whether the device is iPad just from the user-agent string.

(Note: I'm on Snow Leopard which the User Agent string for Safari is

Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_2; en-us) AppleWebKit/531.21.8 (KHTML, like Gecko) Version/4.0.4 Safari/531.21.10

Add below setting to .eslintrc.js / .eslintrc.json to ignore these errors:

  rules: {
    // suppress errors for missing 'import React' in files
   "react/react-in-jsx-scope": "off",
    // allow jsx syntax in js files (for next.js project)
   "react/jsx-filename-extension": [1, { "extensions": [".js", ".jsx"] }], //should add ".ts" if typescript project
  }

Why? If you're using NEXT.js then you do not require to import React at top of files, nextjs does that for you.

You can try this:

print "'%-100s'" % 'hi'

string source = "/once/upon/a/time/";
int count = 0;
foreach (char c in source) 
  if (c == '/') count++;

Has to be faster than the source.Replace() by itself.

There this PHP/Java bridge. This is basically running PHP via FastCGI. I have not used it myself.

All the other answers are correct, but you also need to call your method correctly:

Calculate(5, 5, Operator.PLUS))

And since you use int for left and right, the result will be int as well (3/2 will result in 1). you could cast to double before calculating the result or modify your parameters to accept double

Your going to use the checkbox1.checked property in your if statement, this returns true or false depending on weather it is checked or not.

A small addition to Riley Avron answer to account locale changes:

extension UIButton {
    func centerTextAndImage(spacing: CGFloat) {
        let insetAmount = spacing / 2
        let writingDirection = UIApplication.sharedApplication().userInterfaceLayoutDirection
        let factor: CGFloat = writingDirection == .LeftToRight ? 1 : -1

        self.imageEdgeInsets = UIEdgeInsets(top: 0, left: -insetAmount*factor, bottom: 0, right: insetAmount*factor)
        self.titleEdgeInsets = UIEdgeInsets(top: 0, left: insetAmount*factor, bottom: 0, right: -insetAmount*factor)
        self.contentEdgeInsets = UIEdgeInsets(top: 0, left: insetAmount, bottom: 0, right: insetAmount)
    }
}

Drop database exist in all versions of MySQL. But if you want to keep the table structure, here is an idea

mysqldump --no-data --add-drop-database --add-drop-table -hHOSTNAME -uUSERNAME -p > dump.sql

This is a program, not a mysql command

Then, log into mysql and

source dump.sql;

Here is a crude way to do it: Transform JSON into bash variables to eval them.

This only works for:

• JSON which does not contain nested arrays, and
• JSON from trustworthy sources (else it may confuse your shell script, perhaps it may even be able to harm your system, You have been warned)

Well, yes, it uses PERL to do this job, thanks to CPAN, but is small enough for inclusion directly into a script and hence is quick and easy to debug:

json2bash() {
perl -MJSON -0777 -n -E 'sub J {
my ($p,$v) = @_; my $r = ref $v;
if ($r eq "HASH") { J("${p}_$_", $v->{$_}) for keys %$v; }
elsif ($r eq "ARRAY") { $n = 0; J("$p"."[".$n++."]", $_) foreach @$v; }
else { $v =~ '"s/'/'\\\\''/g"'; $p =~ s/^([^[]*)\[([0-9]*)\](.+)$/$1$3\[$2\]/;
$p =~ tr/-/_/; $p =~ tr/A-Za-z0-9_[]//cd; say "$p='\''$v'\'';"; }
}; J("json", decode_json($_));'
}

use it like eval "$(json2bash <<<'{"a":["b","c"]}')"

Not heavily tested, though. Updates, warnings and more examples see my GIST.

Update

(Unfortunately, following is a link-only-solution, as the C code is far too long to duplicate here.)

For all those, who do not like the above solution, there now is a C program json2sh which (hopefully safely) converts JSON into shell variables. In contrast to the perl snippet, it is able to process any JSON, as long as it is well formed.

Caveats:

• json2sh was not tested much.
• json2sh may create variables, which start with the shellshock pattern () {

I wrote json2sh to be able to post-process .bson with Shell:

bson2json()
{
printf '[';
{ bsondump "$1"; echo "\"END$?\""; } | sed '/^{/s/$/,/';
echo ']';
};

bsons2json()
{
printf '{';
c='';
for a;
do
  printf '%s"%q":' "$c" "$a";
  c=',';
  bson2json "$a";
done;
echo '}';
};

bsons2json */*.bson | json2sh | ..

Explained:

• bson2json dumps a .bson file such, that the records become a JSON array
  • If everything works OK, an END0-Marker is applied, else you will see something like END1.
  • The END-Marker is needed, else empty .bson files would not show up.
• bsons2json dumps a bunch of .bson files as an object, where the output of bson2json is indexed by the filename.

This then is postprocessed by json2sh, such that you can use grep/source/eval/etc. what you need, to bring the values into the shell.

This way you can quickly process the contents of a MongoDB dump on shell level, without need to import it into MongoDB first.

I have my own wrapper for a channel which implements Dispose as follows:

public void Dispose()
{
        try
        {
            if (channel.State == CommunicationState.Faulted)
            {
                channel.Abort();
            }
            else
            {
                channel.Close();
            }
        }
        catch (CommunicationException)
        {
            channel.Abort();
        }
        catch (TimeoutException)
        {
            channel.Abort();
        }
        catch (Exception)
        {
            channel.Abort();
            throw;
        }
}

This seems to work well and allows a using block to be used.

The following resolved the issue:

ScriptEngineManager mgr = new ScriptEngineManager();
ScriptEngine engine = mgr.getEngineByName("JavaScript");
String str = "4*5";
System.out.println(engine.eval(str));

Careful - append() will append HTML, and you may run into cross-site-scripting problems if you use it all the time and a user makes you append('<script>alert("Hello")</script>').

Use text() to replace element content with text, or append(document.createTextNode(x)) to append a text node.

If you want to put multiple conditions in filter, you can use && and || operator.

var product= Object.values(arr_products).filter(x => x.Status==status && x.email==user)

for OS's that support select:

import select

# your code

select.select([], [], [])

Using width/height on inline elements is not always a good idea. You can use display: inline-block instead

@owlstead, regarding your request for "a cryptographically secure variant of one of the given answers," please see RNCryptor. It was designed to do exactly what you're requesting (and was built in response to the problems with the code listed here).

RNCryptor uses PBKDF2 with salt, provides a random IV, and attaches HMAC (also generated from PBKDF2 with its own salt. It support synchronous and asynchronous operation.

As others have pointed out, you need to disable extensions and retry the page to see if errors reoccur. If not, then the culprit might be one (or more) of them.

On my own case it was a deprecated switch, I've set up long ago. I used process-per-tab which was getting phased-out in recent (48-53) versions. Once I removed that switch all started to work correctly.

Support of this type is still very poor. Opera shows it in a way you want. Chrome 23 shows it with seconds and AM/PM, in 24 version (dev branch at this moment) it will rid of seconds (if possible), but no information about AM/PM.
It's not want you possibly want, but at this point the only option I see to achieve your time picker format is usage of javascript.

I liked the Xembly syntax, but it is not a statically typed API. You can get this with XMLBeam:

// Declare a projection
public interface Projection {

    @XBWrite("/root/order/@id")
    Projection setID(int id);

    @XBWrite("/root/order")
    Projection setValue(String value);
}

public static void main(String[] args) {
    // create a projector
    XBProjector projector = new XBProjector();

    // use it to create a projection instance
    Projection projection = projector.projectEmptyDocument(Projection.class);

    // You get a fluent API, with java types in parameters 
    projection.setID(553).setValue("$140.00");

    // Use the projector again to do IO stuff or create an XML-string
    projector.toXMLString(projection);
}

My experience is that this works great even when the XML gets more complicated. You can just decouple the XML structure from your java code structure.

A little more robust version of what you're attempting:

str = str.replaceAll("(\r\n|\n\r|\r|\n)", "<br />");

You can override the default theme used by DialogFragments spawned by an activity by modifying the activity's theme's attributes....

set the activity's theme in AndroidManifest.xml.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.helloworld">

    <application
        android:name=".App"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">     <!-- set all Activity themes to your custom theme -->

        .....

    </application>

</manifest>

in the values/styles.xml, override the item used to determine what theme to use for spawned DialogFragments

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <style name="AppTheme" parent="Theme.AppCompat">

        <!-- override the default theme for DialogFragments -->
        <item name="android:dialogTheme">@style/AppTheme.Dialog</item>

    </style>

    .....

</resources>

in the values/styles.xml, define and configure the theme you want to use for DialogFragments

<?xml version="1.0" encoding="utf-8"?>
<resources>

    .....

    <!--
        configure your custom theme for DialogFragments...
    -->
    <style name="AppTheme.Dialog" parent="Theme.AppCompat.Dialog.MinWidth">

        <!-- override the default theme for DialogFragments spawned by this DialogFragment -->
        <item name="android:dialogTheme">@style/AppTheme.Dialog</item>

        <!--
            OPTIONAL: override the background for the dialog...i am using a dark theme,
            and for some reason, there is no themes for dialogs with dark backgrounds,
            so, i made my own.
        -->
        <item name="android:windowBackground">@drawable/dialog__window_background</item>

        <!--
            add the title to the dialog's theme. you can remove it later by using
            DialogFragment.setStyle()
        -->
        <item name="android:windowNoTitle">false</item>
        <item name="windowNoTitle">?android:windowNoTitle</item>

    </style>

    .....

</resources>

OPTIONAL: if you use a dark theme, and overrode android:windowBackground like i did in AppTheme.Dialog, then add a drawable/dialog__window_background.xml file with the contents:

<?xml version="1.0" encoding="utf-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
    android:insetLeft="16dp"
    android:insetTop="16dp"
    android:insetRight="16dp"
    android:insetBottom="16dp">
    <shape android:shape="rectangle">
        <corners android:radius="?dialogCornerRadius" />
        <solid android:color="?android:colorBackground" />
    </shape>
</inset>

The best way in my eyes is to use the concat() method provided by the String class itself.

The useage would, in your case, look like this:

String myConcatedString = cursor.getString(numcol).concat('-').
       concat(cursor.getString(cursor.getColumnIndexOrThrow(db.KEY_DESTINATIE)));

if you want not the copies; then the best way is to use a pointer vector(or another structure that serves for the same goal). if you want the copies; use directly push_back(). you dont have any other choice.

I agree it is generally preferable to use an Array for this.

However, this can also be accomplished in JavaScript by simply adding properties to the current scope (the global scope, if top-level code; the function scope, if within a function) by simply using this – which always refers to the current scope.

for (var i = 0; i < coords.length; ++i) {
    this["marker"+i] = "some stuff";
}

You can later retrieve the stored values (if you are within the same scope as when they were set):

var foo = this.marker0;
console.log(foo); // "some stuff"

This slightly odd feature of JavaScript is rarely used (with good reason), but in certain situations it can be useful.

If the attribute is matching f.text_field in form use string, if it is matching f.text_area use text.

www.bitvise.com - sftpc is a good command line client also.

Im my browser, this doesn't work at all. The tooltip field doesn't show a link, but <a href='#' onClick='alert('Hello World!')>The Link</a>. I'm using FF 3.6.12.

You'll have to do this by hand with JS and CSS. Begin here

I've been looking for a lightweight, dependency free dual slider for some time (it seemed crazy to import jQuery just for this) and there don't seem to be many out there. I ended up modifying @Wildhoney's code a bit and really like it.

function getVals(){_x000D_
  // Get slider values_x000D_
  var parent = this.parentNode;_x000D_
  var slides = parent.getElementsByTagName("input");_x000D_
    var slide1 = parseFloat( slides[0].value );_x000D_
    var slide2 = parseFloat( slides[1].value );_x000D_
  // Neither slider will clip the other, so make sure we determine which is larger_x000D_
  if( slide1 > slide2 ){ var tmp = slide2; slide2 = slide1; slide1 = tmp; }_x000D_
  _x000D_
  var displayElement = parent.getElementsByClassName("rangeValues")[0];_x000D_
      displayElement.innerHTML = slide1 + " - " + slide2;_x000D_
}_x000D_
_x000D_
window.onload = function(){_x000D_
  // Initialize Sliders_x000D_
  var sliderSections = document.getElementsByClassName("range-slider");_x000D_
      for( var x = 0; x < sliderSections.length; x++ ){_x000D_
        var sliders = sliderSections[x].getElementsByTagName("input");_x000D_
        for( var y = 0; y < sliders.length; y++ ){_x000D_
          if( sliders[y].type ==="range" ){_x000D_
            sliders[y].oninput = getVals;_x000D_

Found a step-by-step way to achieve this (for 1 font):
(as of Sep-9 2013)

1. Choose your font at http://www.google.com/fonts
2. Add the desired one to your collection using "Add to collection" blue button
3. Click the "See all styles" button near "Remove from collection" button and make sure that you have selected other styles you may also need such as 'bold'...
4. Click the 'Use' tab button on bottom right of the page
5. Click the download button on top with a down arrow image
6. Click on "zip file" on the the popup message that appears
7. Click "Close" button on the popup
8. Slowly scroll the page until you see the 3 tabs "Standrd|@import|Javascript"
9. Click "@import" tab
10. Select and copy the url between 'url(' and ')'
11. Copy it on address bar in a new tab and go there
12. Do "File > Save page as..." and name it "desiredfontname.css" (replace accordingly)
13. Decompress the fonts .zip file you downloaded (.ttf should be extracted)
14. Go to "http://ttf2woff.com/" and convert any .ttf extracted from zip to .woff
15. Edit desiredfontname.css and replace any url within it [between 'url(' and ')'] with the corresponding converted .woff file you got on ttf2woff.com; path you write should be according to your server doc_root
16. Save the file and move it at its final place and write the corresponding <link/> CSS tag to import these in your HTML page
17. From now, refer to this font by its font-family name in your styles

That's it. Cause I had the same problem and the solution on top did not work for me.

In Visual Basic, you can call a parameterless method without the braces (()). In C#, they're mandatory. So you should write:

String guid = System.Guid.NewGuid().ToString();

Without the braces, you're assigning the method itself (instead of its result) to the variable guid, and obviously the method cannot be converted to a String, hence the error.

For converting a list of dictionaries to a pandas DataFrame, you can use "append":

We have a dictionary called dic and dic has 30 list items (list1, list2,…, list30)

1. step1: define a variable for keeping your result (ex: total_df)
2. step2: initialize total_df with list1
3. step3: use "for loop" for append all lists to total_df

total_df=list1
nums=Series(np.arange(start=2, stop=31))
for num in nums:
    total_df=total_df.append(dic['list'+str(num)])

It downloads the (debug) symbols from the device, so it becomes possible to debug on devices with that specific iOS version and also to symbolicate crash reports that happened on that iOS version.

Since symbols are CPU specific, the above only works if you have imported the symbols not only for a specific iOS device but also for a specific CPU type. The currently CPU types needed are armv7 (e.g. iPhone 4, iPhone 4s), armv7s (e.g. iPhone 5) and arm64 (e.g. iPhone 5s).

So if you want to symbolicate a crash report that happened on an iPhone 5 with armv7s and only have the symbols for armv7 for that specific iOS version, Xcode won't be able to (fully) symbolicate the crash report.

Declare your progress dialog:

ProgressDialog progress;

When you're ready to start the progress dialog:

progress = ProgressDialog.show(this, "dialog title",
    "dialog message", true);

and to make it go away when you're done:

progress.dismiss();

Here's a little thread example for you:

// Note: declare ProgressDialog progress as a field in your class.

progress = ProgressDialog.show(this, "dialog title",
  "dialog message", true);

new Thread(new Runnable() {
  @Override
  public void run()
  {
    // do the thing that takes a long time

    runOnUiThread(new Runnable() {
      @Override
      public void run()
      {
        progress.dismiss();
      }
    });
  }
}).start();

You can use COALESCE:

SELECT  orderhed.ordernum, 
    orderhed.orderdate, 
    currrate.currencycode,  
    coalesce(currrate.currentrate, 1) as currentrate
FROM orderhed 
LEFT OUTER JOIN currrate 
    ON orderhed.company = currrate.company 
    AND orderhed.orderdate = currrate.effectivedate

Or even IsNull():

SELECT  orderhed.ordernum, 
    orderhed.orderdate, 
    currrate.currencycode,  
    IsNull(currrate.currentrate, 1) as currentrate
FROM orderhed 
LEFT OUTER JOIN currrate 
    ON orderhed.company = currrate.company 
    AND orderhed.orderdate = currrate.effectivedate

Here is an article to help decide between COALESCE and IsNull:

http://www.mssqltips.com/sqlservertip/2689/deciding-between-coalesce-and-isnull-in-sql-server/

$alphabet = array('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z');

Some times If you touch the keyboard accidentally and removed a space.

if [ "$myvar" = "something"]; then
    do something
fi

Will trigger this error message. Note the space before ']' is required.

This is what then SQL2003 standard (§6.1 Data Types) says about the two:

 <exact numeric type> ::=
    NUMERIC [ <left paren> <precision> [ <comma> <scale> ] <right paren> ]
  | DECIMAL [ <left paren> <precision> [ <comma> <scale> ] <right paren> ]
  | DEC [ <left paren> <precision> [ <comma> <scale> ] <right paren> ]
  | SMALLINT
  | INTEGER
  | INT
  | BIGINT

 ...

21) NUMERIC specifies the data type
    exact numeric, with the decimal
    precision and scale specified by the
    <precision> and <scale>.

22) DECIMAL specifies the data type
    exact numeric, with the decimal scale
    specified by the <scale> and the
    implementation-defined decimal
    precision equal to or greater than the
    value of the specified <precision>.

The general theory can be found in wikipedia's article on Kademlia. The specific protocol specification used in bittorrent is here: http://wiki.theory.org/BitTorrentDraftDHTProtocol

If you need to take grapheme clusters into account, use regexp or unicode module. Counting the number of code points(runes) or bytes also is needed for validaiton since the length of grapheme cluster is unlimited. If you want to eliminate extremely long sequences, check if the sequences conform to stream-safe text format.

package main

import (
    "regexp"
    "unicode"
    "strings"
)

func main() {

    str := "\u0308" + "a\u0308" + "o\u0308" + "u\u0308"
    str2 := "a" + strings.Repeat("\u0308", 1000)

    println(4 == GraphemeCountInString(str))
    println(4 == GraphemeCountInString2(str))

    println(1 == GraphemeCountInString(str2))
    println(1 == GraphemeCountInString2(str2))

    println(true == IsStreamSafeString(str))
    println(false == IsStreamSafeString(str2))
}


func GraphemeCountInString(str string) int {
    re := regexp.MustCompile("\\PM\\pM*|.")
    return len(re.FindAllString(str, -1))
}

func GraphemeCountInString2(str string) int {

    length := 0
    checked := false
    index := 0

    for _, c := range str {

        if !unicode.Is(unicode.M, c) {
            length++

            if checked == false {
                checked = true
            }

        } else if checked == false {
            length++
        }

        index++
    }

    return length
}

func IsStreamSafeString(str string) bool {
    re := regexp.MustCompile("\\PM\\pM{30,}") 
    return !re.MatchString(str) 
}

This is a pretty old question but i think still relevant. Also the accepted answer works only for String. Meanwhile there is Mockito 2.1 and some imports have changed, so i would like to share my current answer:

import static org.mockito.AdditionalAnswers.returnsFirstArg;
import static org.mockito.ArgumentMatchers.any;
import static org.mockito.Mockito.when;

@Mock
private MyClass myClass;

// this will return anything you pass, but it's pretty unrealistic
when(myClass.myFunction(any())).then(returnsFirstArg());
// it is more "life-like" to accept only the right type
when(myClass.myFunction(any(ClassOfArgument.class))).then(returnsFirstArg());

The myClass.myFunction would look like:

public class MyClass {
    public ClassOfArgument myFunction(ClassOfArgument argument){
        return argument;
    }  
}

Sure you can use isinstance, but be aware that this is not how Python works. Python is a duck typed language. You should not explicitly check your types. A TypeError will be raised if the incorrect type was passed.

So just assume it is an int. Don't bother checking.
