code:

a="http://www.example.com"
try:    
    print urllib.urlopen(a)
except:
    print a+"  site does not exist"

Maybe because other languages do this as well, so it is generally-accepted behavior. (For good reasons, as shown in the other answers)

In as few words as possible:

• managed code = .NET programs
• unmanaged code = "normal" programs

This seems to be updated again as of May 19, 2015:

How I got it to work:

As in jmbertucci's recently updated answer, make your folder public to everyone. This is a bit more complicated than before, you have to click Advanced to change the folder to "On - Public on the web."

Find your folder UUID as before--just go into the folder and find your UUID in the address bar:

https://drive.google.com/drive/folders/<folder UUID>

Then head to

https://googledrive.com/host/<folder UUID>

It will redirect you to an index type page with a giant subdomain, but you should be able to see the files in your folder. Then you can right click to save the link to the file you want (I noticed that this direct link also has this big subdomain for googledrive.com). Worked great for me with wget.

This also seems to work with others' shared folders.

e.g.,

https://drive.google.com/folderview?id=0B7l10Bj_LprhQnpSRkpGMGV2eE0&usp=sharing

maps to

https://googledrive.com/host/0B7l10Bj_LprhQnpSRkpGMGV2eE0

And a right click can save a direct link to any of those files.

You can somehow reproduce the behavior of "OR" using & and :not.

SomeElement.SomeClass [data-statement="things are getting more complex"]  :not(:not(A):not(B))     {
    /* things aren't so complex for A or B */
}

Thanks to dimo414's answer, this shows how his great solution works, and shows that you can have quotes and variables in the text easily as well:

example output

$ ./test.sh

The text from the example function is:
  Welcome dev: Would you "like" to know how many 'files' there are in /tmp?

  There are "      38" files in /tmp, according to the "wc" command

test.sh

#!/bin/bash

function text1()
{
  COUNT=$(\ls /tmp | wc -l)
cat <<EOF

  $1 Would you "like" to know how many 'files' there are in /tmp?

  There are "$COUNT" files in /tmp, according to the "wc" command

EOF
}

function main()
{
  OUT=$(text1 "Welcome dev:")
  echo "The text from the example function is: $OUT"
}

main

Simply use if ($web). This is true if the variable has any truthy value.

You don't need isset or empty since you know the variable exists, since you have just set it in the previous line.

I fixed it with Datejs

This is alerting the first day:

var fd = Date.today().clearTime().moveToFirstDayOfMonth();
var firstday = fd.toString("MM/dd/yyyy");
alert(firstday);

This is for the last day:

var ld = Date.today().clearTime().moveToLastDayOfMonth();
var lastday = ld.toString("MM/dd/yyyy");
alert(lastday);

I've been playing around with the Google Autocomplete API for a bit and here's the best solution I could find for limiting your results to only countries:

var autocomplete = new google.maps.places.Autocomplete(input, options);
var result = autocomplete.getPlace();
console.log(result); // take a look at this result object
console.log(result.address_components); // a result has multiple address components

for(var i = 0; i < result.address_components.length; i += 1) {
  var addressObj = result.address_components[i];
  for(var j = 0; j < addressObj.types.length; j += 1) {
    if (addressObj.types[j] === 'country') {
      console.log(addressObj.types[j]); // confirm that this is 'country'
      console.log(addressObj.long_name); // confirm that this is the country name
    }
  }
}

If you look at the result object that's returned, you'll see that there's an address_components array which will contain several objects representing different parts of an address. Within each of these objects, it will contain a 'types' array and within this 'types' array, you'll see the different labels associated with an address, including one for country.

Also check to see if you are missing the www in the url which was on my case

i was testing on http://www.mywebsite.com and in the facebook app i had set http://mywebsite.com

May be universe repository is disabled, here is your package in it

Enable it

sudo add-apt-repository universe

Update

sudo apt-get update

And install

sudo apt-get install php5-intl

If you can use Interactive SQL:

1 - Create a .BAT file with this code:

@ECHO OFF ECHO
for %%G in (*.sql) do dbisql -c "uid=dba;pwd=XXXXXXXX;ServerName=INSERT-DB-NAME-HERE" %%G
pause

2 - Change the pwd and ServerName.

3 - Put the .BAT file in the folder that contains .SQL files and run it.

Heredoc's are a great alternative to quoted strings because of increased readability and maintainability. You don't have to escape quotes and (good) IDEs or text editors will use the proper syntax highlighting.

A very common example: echoing out HTML from within PHP:

$html = <<<HTML
  <div class='something'>
    <ul class='mylist'>
      <li>$something</li>
      <li>$whatever</li>
      <li>$testing123</li>
    </ul>
  </div>
HTML;

// Sometime later
echo $html;

It is easy to read and easy to maintain.

The alternative is echoing quoted strings, which end up containing escaped quotes and IDEs aren't going to highlight the syntax for that language, which leads to poor readability and more difficulty in maintenance.

Updated answer for Your Common Sense

Of course you wouldn't want to see an SQL query highlighted as HTML. To use other languages, simply change the language in the syntax:

$sql = <<<SQL
       SELECT * FROM table
SQL;

Yes, you can access it through GET and POST (trying this simple task would have made you aware of that).

Yes, there are other ways, one of the other "preferred" ways is using sessions. When you would want to use hidden over session is kind of touchy, but any GET / POST data is easily manipulated by the end user. A session is a bit more secure given it is saved to a file on the server and it is much harder for the end user to manipulate without access through the program.

There is an underlying buffer/stream that getchar() and friends read from. When you enter text, the text is stored in a buffer somewhere. getchar() can stream through it one character at a time. Each read returns the next character until it reaches the end of the buffer. The reason it's not asking you for subsequent characters is that it can fetch the next one from the buffer.

If you run your script and type directly into it, it will continue to prompt you for input until you press CTRL+D (end of file). If you call it like ./program < myInput where myInput is a text file with some data, it will get the EOF when it reaches the end of the input. EOF isn't a character that exists in the stream, but a sentinel value to indicate when the end of the input has been reached.

As an extra warning, I believe getchar() will also return EOF if it encounters an error, so you'll want to check ferror(). Example below (not tested, but you get the idea).

main() {
    int c;
    do {
        c = getchar();
        if (c == EOF && ferror()) {
            perror("getchar");
        }
        else {
            putchar(c);
        }
    }
    while(c != EOF);
}

Previously I'm using onAttach (Activity activity) to get context in Fragment

Problem

The onAttach (Activity activity) method was deprecated in API level 23.

Solution

Now to get context in Fragment we can use onAttach (Context context)

onAttach (Context context)

• Called when a fragment is first attached to its context. onCreate(Bundle) will be called after this.

Documentation

/**
 * Called when a fragment is first attached to its context.
 * {@link #onCreate(Bundle)} will be called after this.
 */
@CallSuper
public void onAttach(Context context) {
    mCalled = true;
    final Activity hostActivity = mHost == null ? null : mHost.getActivity();
    if (hostActivity != null) {
        mCalled = false;
        onAttach(hostActivity);
    }
}

SAMPLE CODE

public class FirstFragment extends Fragment {


    private Context mContext;
    public FirstFragment() {
        // Required empty public constructor
    }

    @Override
    public void onAttach(Context context) {
        super.onAttach(context);
        mContext=context;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View rooView=inflater.inflate(R.layout.fragment_first, container, false);

        Toast.makeText(mContext, "THIS IS SAMPLE TOAST", Toast.LENGTH_SHORT).show();
        // Inflate the layout for this fragment
        return rooView;
    }

}

NOTE

We can also use getActivity() to get context in Fragments but getActivity() can return null if the your fragment is not currently attached to a parent activity,

If you are running puppet it may set /proc/sys/kernel/modules_disabled to 1, inhibiting further module loading. When the machine is reboot, it gets set back to 0, allowing for changes, such as loading the iptables modules. After a certain amount of time puppet will set it back to 1 to protect the system from kernel root kits. Therefore, whatever modules that we are going to need should be loaded during or shortly after boot time.

I've created .gitignore using echo "..." > .gitignore in PowerShell in Windows, because it does not let me to create it in Windows Explorer.

The problem in my case was the encoding of the created file, and the problem was solved after I changed it to ANSI.

GitHub for Windows on Windows 7 currently installs Git in a path similar to this:

C:\Users\{username}\AppData\Local\GitHub\PortableGit_93e8418133eb85e81a81e5e19c272776524496c6\bin\git.exe

The guid after PortableGit_ may well be different on your system.

@Entity(tableName = "user")
data class User(

@PrimaryKey(autoGenerate = true)  var id: Int?,
       var name: String,
       var dob: String,
       var address: String,
       var gender: String
)
{
    constructor():this(null,
        "","","","")
}

time after 30 min, this easiest solution in php

date('Y-m-d H:i:s', strtotime("+30 minutes"));

for DateTime class (PHP 5 >= 5.2.0, PHP 7)

$dateobj = new DateTime();
$dateobj ->modify("+30 minutes"); 

I know this is an old post but as MisterZimbu stated, the color property is defining the values of other properties, as the border-color and, with CSS3, of currentColor.

currentColor is very handy if you want to use the font color for other elements (as the background or custom checkboxes and radios of inner elements for example).

Example:

.element {_x000D_
  color: green;_x000D_
  background: red;_x000D_
  display: block;_x000D_
  width: 200px;_x000D_
  height: 200px;_x000D_
  padding: 0;_x000D_
  margin: 0;_x000D_
}_x000D_
_x000D_
.innerElement1 {_x000D_
  border: solid 10px;_x000D_
  display: inline-block;_x000D_
  width: 60px;_x000D_
  height: 100px;_x000D_
  margin: 10px;_x000D_
}_x000D_
_x000D_
.innerElement2 {_x000D_
  background: currentColor;_x000D_
  display: inline-block;_x000D_
  width: 60px;_x000D_
  height: 100px;_x000D_
  margin: 10px;_x000D_
}

<div class="element">_x000D_
  <div class="innerElement1"></div>_x000D_
  <div class="innerElement2"></div>_x000D_

I was having the same issue

Role.java

 @ManyToMany(mappedBy = "roles", fetch = FetchType.LAZY,cascade = CascadeType.ALL)
 Set<BusinessUnitMaster> businessUnits =new HashSet<>();

BusinessUnitMaster.java

@ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
@JoinTable(
        name = "BusinessUnitRoles",
        joinColumns = {@JoinColumn(name = "unit_id", referencedColumnName = "record_id")},
        inverseJoinColumns = {@JoinColumn(name = "role_id", referencedColumnName = "record_id")}
)
private Set<Role> roles=new HashSet<>();

the problem is that when you create BusinessUnitMaster and Role you have to save the object for both sides for RoleService.java

roleRepository.save(role);

for BusinessUnitMasterService.java

businessUnitMasterRepository.save(businessUnitMaster);

 void main(){
  var x = "4";
  int number = int.parse(x);//STRING to INT

  var y = "4.6";
  double doubleNum = double.parse(y);//STRING to DOUBLE

  var z = 55;
  String myStr = z.toString();//INT to STRING
}

int.parse() and double.parse() can throw an error when it couldn't parse the String

Since PHP 5.4.0 you can use getallheaders function which returns all request headers as an associative array:

var_dump(getallheaders());

// array(8) {
//   ["Accept"]=>
//   string(63) "text/html[...]"
//   ["Accept-Charset"]=>
//   string(31) "ISSO-8859-1[...]"
//   ["Accept-Encoding"]=>
//   string(17) "gzip,deflate,sdch"
//   ["Accept-Language"]=>
//   string(14) "en-US,en;q=0.8"
//   ["Cache-Control"]=>
//   string(9) "max-age=0"
//   ["Connection"]=>
//   string(10) "keep-alive"
//   ["Host"]=>
//   string(9) "localhost"
//   ["User-Agent"]=>
//   string(108) "Mozilla/5.0 (Windows NT 6.1; WOW64) [...]"
// }

Earlier this function worked only when PHP was running as an Apache/NSAPI module.

You need to use HAVING, not WHERE.

The difference is: the WHERE clause filters which rows MySQL selects. Then MySQL groups the rows together and aggregates the numbers for your COUNT function.

HAVING is like WHERE, only it happens after the COUNT value has been computed, so it'll work as you expect. Rewrite your subquery as:

(                  -- where that pid is in the set:
SELECT c2.pid                  -- of pids
FROM Catalog AS c2             -- from catalog
WHERE c2.pid = c1.pid
HAVING COUNT(c2.sid) >= 2)

int i;
int j;

int * const ptr1 = &i;

The compiler will stop you changing ptr1.

const int * ptr2 = &i;

The compiler will stop you changing *ptr2.

ptr1 = &j; // error
*ptr1 = 7; // ok

ptr2 = &j; // ok
*ptr2 = 7; // error

Note that you can still change *ptr2, just not by literally typing *ptr2:

i = 4;
printf("before: %d\n", *ptr2); // prints 4
i = 5;
printf("after: %d\n", *ptr2); // prints 5
*ptr2 = 6; // still an error

You can also have a pointer with both features:

const int * const ptr3 = &i;

ptr3 = &j; // error
*ptr3 = 7; // error

Just Install EntityFramework package to your Web/Console Project. That should add the section to your config file.

Try the following:

<script> 
 //Functions to open database and to create, insert data into tables

 getSelectedRow = function(val)
    {
        db.transaction(function(transaction) {
              transaction.executeSql('SELECT * FROM Employ where number = ?;',[parseInt(val)], selectedRowValues, errorHandler);

        });
    };
    selectedRowValues = function(transaction,results)
    {
         for(var i = 0; i < results.rows.length; i++)
         {
             var row = results.rows.item(i);
             alert(row['number']);
             alert(row['name']);                 
         }
    };
</script>

You don't have access to javascript variable names in SQL, you must pass the values to the Database.

We had the same error even though the user was properly mapped to the login.

After trying to delete the user it was discovered that a few SPs contained "with execute as" that user.

The issue was solved by dropping those SPs, dropping the user, recreating the user linked to login, and recreating the SPs.

Possibly it got in this state from restoring from backup (during a time when the related login didn't exist) or bulk schema syncing (if its possible to create an SP with execute as even though the user doesn't exist. Could also have been related to this answer.

SELECT CAST(GETDATE() AS DATE)

Returns the current date with the time part removed.

DATETIMEs are not "stored in the following format". They are stored in a binary format.

SELECT CAST(GETDATE() AS BINARY(8))

The display format in the question is independent of storage.

Formatting into a particular display format should be done by your application.

putting "\r" at the end of each row actually had the effect of line breaks in excel, but in the .csv it vanished and left an ugly mess where each row was squashed against the next with no space and no line-breaks

Controller

public ActionResult Index()
    {


        //you don't need to include the category bc it does it by itself
        //var model = db.Product.Include(c => c.Category).ToList()

        ViewBag.Categories = db.Category.OrderBy(c => c.Name).ToList();
        var model = db.Product.ToList()
        return View(model);
    }

View

you need to filter the model with the given category

like :=> Model.where(p=>p.CategoryID == category.CategoryID)

try this...

@foreach (var category in ViewBag.Categories)
{
    <h3><u>@category.Name</u></h3>

    <div>

        @foreach (var product in Model.where(p=>p.CategoryID == category.CategoryID))
        {

                                @product.Title

                                {
                                    @Html.Raw(" - ")  
                                    @Html.ActionLink("Edit", "Edit", new { id = product.ID }, new { style = "background-color:black; color:white !important;" })
                                }
                            </th>
                        </tr>
                    </thead>

                    <tbody>
                        <tr>
                            <td style="background-color:White;">
                                @product.Description
                            </td>
                        </tr>
                    </tbody>      
                </table>                       
            }


    </div>
}  

From your comment:

this line DateTime Date = reader.GetDateTime(0); was throwing the exception

The first column is not a valid DateTime. Most likely, you have multiple columns in your table, and you're retrieving them all by running this query:

SELECT * from INFO

Replace it with a query that retrieves only the two columns you're interested in:

SELECT YOUR_DATE_COLUMN, YOUR_TIME_COLUMN from INFO

Then try reading the values again:

var Date = reader.GetDateTime(0);
var Time = reader.GetTimeSpan(1);  // equivalent to time(7) from your database

Or:

var Date = Convert.ToDateTime(reader["YOUR_DATE_COLUMN"]);
var Time = (TimeSpan)reader["YOUR_TIME_COLUMN"];

That depends on what you actually want to achieve.

You want to keep on making normal Java-based Android application, but use Visual Studio for development? Then it's bad news, as Visual Studio has no built-in java support. Thus, if you use it out-of-the-box, you will lose all Java-specific Eclipse functionality (IntelliSense for Java, Java debugger, wizards, etc) as well as numerous Android plugins (that are Eclipse-specific and won't work with VS).

On the other hand, you can use Mono for Android to develop apps in C# in VS, but they won't look as smooth as the native apps (some functionality might be missing, look-and-feel slightly different, etc.). In that case such app could sell less than a "normal" Java app that looks and feels like all other Java apps.

If you are talking about native Android code (in C/C++), such as games, the news are not as bad. As Visual Studio has no problem with C++, there are numerous ways to make it work:

1. If you only want to compile your code, you can use the free vs-android toolset. It's essentially a set of build rules telling Visual Studio how to launch Android compiler.

2. If you want to compile and debug your native code with Visual Studio, you will need something more advanced, such as VisualGDB for Android. It can build/debug your Native code independently, or together with debugging Java code from Eclipse.

public static Boolean freq[] = new Boolean[Global.iParameter[2]];

Global.iParameter[2]:

It should be const value

You can also try and provide an Id for the main layout and change the background of that through basic manipulation and retrieval. E.g:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/hello"

Which can then be followed by accessing through R.id.hello.... Pretty basic and I hope this does help :)

Preview in OS X seems to be able to do this out of the box. Adobe Reader shows the doc as "data typed can't be saved" but Preview was able to save my changes without hassle.

It is possible to rename a file and keep the history intact, although it causes the file to be renamed throughout the entire history of the repository. This is probably only for the obsessive git-log-lovers, and has some serious implications, including these:

• You could be rewriting a shared history, which is the most important DON'T while using Git. If someone else has cloned the repository, you'll break it doing this. They will have to re-clone to avoid headaches. This might be OK if the rename is important enough, but you'll need to consider this carefully -- you might end up upsetting an entire opensource community!
• If you've referenced the file using it's old name earlier in the repository history, you're effectively breaking earlier versions. To remedy this, you'll have to do a bit more hoop jumping. It's not impossible, just tedious and possibly not worth it.

Now, since you're still with me, you're a probably solo developer renaming a completely isolated file. Let's move a file using filter-tree!

Assume you're going to move a file old into a folder dir and give it the name new

This could be done with git mv old dir/new && git add -u dir/new, but that breaks history.

Instead:

git filter-branch --tree-filter 'if [ -f old ]; then mkdir dir && mv old dir/new; fi' HEAD

will redo every commit in the branch, executing the command in the ticks for each iteration. Plenty of stuff can go wrong when you do this. I normally test to see if the file is present (otherwise it's not there yet to move) and then perform the necessary steps to shoehorn the tree to my liking. Here you might sed through files to alter references to the file and so on. Knock yourself out! :)

When completed, the file is moved and the log is intact. You feel like a ninja pirate.

Also; The mkdir dir is only necessary if you move the file to a new folder, of course. The if will avoid the creation of this folder earlier in history than your file exists.

Just create a new branch:

git checkout -b newBranch

And if you do git status you'll see that the state of the code hasn't changed and you can commit it to the new branch.

Try this:

//Vista or higher check
if (System.Environment.OSVersion.Version.Major >= 6)
{
   p.StartInfo.Verb = "runas";
}

Alternatively, go the manifest route for your application.

You really need to look at the state part of the error message to find the root cause of the issue.

2, 5 = Invalid userid
6 = Attempt to use a Windows login name with SQL Authentication
7 = Login disabled and password mismatch
8 = Password mismatch
9 = Invalid password
11, 12 = Valid login but server access failure
13 = SQL Server service paused
18 = Change password required

Afterwards, Google how to fix the issue.

The code in your example looks fine at first glance. BTW, if the server timestamp is in UTC (i.e. it's an epoch timestamp) then you should not have to apply the current timezone offset. In other words if the server timestamp is in UTC then you can simply get the difference between the server timestamp and the system time (System.currentTimeMillis()) as the system time is in UTC (epoch).

I would check that the timestamp coming from your server is what you expect. If the timestamp from the server does not convert into the date you expect (in the local timezone) then the difference between the timestamp and the current system time will not be what you expect.

Use Calendar to get the current timezone. Initialize a SimpleDateFormatter with the current timezone; then log the server timestamp and verify if it's the date you expect:

Calendar cal = Calendar.getInstance();
TimeZone tz = cal.getTimeZone();

/* debug: is it local time? */
Log.d("Time zone: ", tz.getDisplayName());

/* date formatter in local timezone */
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
sdf.setTimeZone(tz);

/* print your timestamp and double check it's the date you expect */
long timestamp = cursor.getLong(columnIndex);
String localTime = sdf.format(new Date(timestamp * 1000)); // I assume your timestamp is in seconds and you're converting to milliseconds?
Log.d("Time: ", localTime);

If the server time that is printed is not what you expect then your server time is not in UTC.

If the server time that is printed is the date that you expect then you should not have to apply the rawoffset to it. So your code would be simpler (minus all the debug logging):

long timestamp = cursor.getLong(columnIndex);
Log.d("Server time: ", timestamp);

/* log the device timezone */
Calendar cal = Calendar.getInstance();
TimeZone tz = cal.getTimeZone();
Log.d("Time zone: ", tz.getDisplayName());

/* log the system time */
Log.d("System time: ", System.currentTimeMillis());

CharSequence relTime = DateUtils.getRelativeTimeSpanString(
    timestamp * 1000,
    System.currentTimeMillis(),
    DateUtils.MINUTE_IN_MILLIS);

((TextView) view).setText(relTime);

Here is the Solution i work with. Without RegEx and String.Split.

public static string TrimWhiteSpace(this string Value)
{
    StringBuilder sbOut = new StringBuilder();
    if (!string.IsNullOrEmpty(Value))
    {
        bool IsWhiteSpace = false;
        for (int i = 0; i < Value.Length; i++)
        {
            if (char.IsWhiteSpace(Value[i])) //Comparion with WhiteSpace
            {
                if (!IsWhiteSpace) //Comparison with previous Char
                {
                    sbOut.Append(Value[i]);
                    IsWhiteSpace = true;
                }
            }
            else
            {
                IsWhiteSpace = false;
                sbOut.Append(Value[i]);
            }
        }
    }
    return sbOut.ToString();
}

so you can:

string cleanedString = dirtyString.TrimWhiteSpace();

There is no simple command available to find out the largest files/directories on a Linux/UNIX/BSD filesystem. However, combination of following three commands (using pipes) you can easily find out list of largest files:

# du -a /var | sort -n -r | head -n 10

If you want more human readable output try:

$ cd /path/to/some/var
$ du -hsx * | sort -rh | head -10

Where,

• Var is the directory you wan to search
• du command -h option : display sizes in human readable format (e.g., 1K, 234M, 2G).
• du command -s option : show only a total for each argument (summary).
• du command -x option : skip directories on different file systems.
• sort command -r option : reverse the result of comparisons.
• sort command -h option : compare human readable numbers. This is GNU sort specific option only.
• head command -10 OR -n 10 option : show the first 10 lines.

One thing that caused me a massive headache when using this code (might affect others and I wish that somebody had left a comment like this one here for me to read):

• My aim is to create a dynamic access dashboard, which requires that its linked tables be updated.
• I use the copy methods described above to replace the existing linked CSVs with an updated version of them.
• Running the above code manually from a module worked fine.
• Running identical code from a form linked to the CSV data had runtime error 70 (Permission denied), even tho the first step of my code was to close that form (which should have unlocked the CSV file so that it could be overwritten).
• I now believe that despite the form being closed, it keeps the outdated CSV file locked while it executes VBA associated with that form.

My solution will be to run the code (On timer event) from another hidden form that opens with the database.

You need to do something like this:

// instantiate XmlDocument and load XML from file
XmlDocument doc = new XmlDocument();
doc.Load(@"D:\test.xml");

// get a list of nodes - in this case, I'm selecting all <AID> nodes under
// the <GroupAIDs> node - change to suit your needs
XmlNodeList aNodes = doc.SelectNodes("/Equipment/DataCollections/GroupAIDs/AID");

// loop through all AID nodes
foreach (XmlNode aNode in aNodes)
{
   // grab the "id" attribute
   XmlAttribute idAttribute = aNode.Attributes["id"];

   // check if that attribute even exists...
   if (idAttribute != null)
   {
      // if yes - read its current value
      string currentValue = idAttribute.Value;

      // here, you can now decide what to do - for demo purposes,
      // I just set the ID value to a fixed value if it was empty before
      if (string.IsNullOrEmpty(currentValue))
      {
         idAttribute.Value = "515";
      }
   }
}

// save the XmlDocument back to disk
doc.Save(@"D:\test2.xml");

This is another solution in PHP 7.1

     /**
     * @param array $input    Input array to add items to
     * @param array $items    Items to insert (as an array)
     * @param int   $position Position to inject items from (starts from 0)
     *
     * @return array
     */
    function arrayInject( array $input, array $items, int $position ): array 
    {
        if (0 >= $position) {
            return array_merge($items, $input);
        }
        if ($position >= count($input)) {
            return array_merge($input, $items);
        }

        return array_merge(
            array_slice($input, 0, $position, true),
            $items,
            array_slice($input, $position, null, true)
        );
    }

When you have the expression:

a % b = c

It really means there exists an integer n that makes c as small as possible, but non-negative.

a - n*b = c

By hand, you can just subtract 2 (or add 2 if your number is negative) over and over until the end result is the smallest positive number possible:

  3.14 % 2
= 3.14 - 1 * 2
= 1.14

Also, 3.14 % 2 * pi is interpreted as (3.14 % 2) * pi. I'm not sure if you meant to write 3.14 % (2 * pi) (in either case, the algorithm is the same. Just subtract/add until the number is as small as possible).

SELECT convert(datetime, '23/07/2009', 103)

In case you need to convert a timeval struct (seconds, microseconds) containing UNIX time to DateTime without losing precision, this is how:

DateTime _epochTime = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
private DateTime UnixTimeToDateTime(Timeval unixTime)
{
    return _epochTime.AddTicks(
        unixTime.Seconds * TimeSpan.TicksPerSecond +
        unixTime.Microseconds * TimeSpan.TicksPerMillisecond/1000);
}

Other solutions are good enough to answer your query. However, if you are looking for just one command to do that for you -

Create a file name "run", in directory where your Java files are. And save this in your file -

javac "$1.java"
if [ $? -eq 0 ]; then
  echo "--------Run output-------"
  java "$1"
fi

give this file run permission by running -

chmod 777 

Now you can run any of your files by merely running -

./run <yourfilename> (don't add .java in filename)

Inspired by @ahmed_khan_89 answer above. We can directly keep like this in gradle file.

android{

// set build flavor here to get the right Google-services configuration(Google Analytics).
    def currentFlavor = "free" //This should match with Build Variant selection. free/paidFull/paidBasic

    println "--> $currentFlavor copy!"
    copy {
        from "src/$currentFlavor/"
        include 'google-services.json'
        into '.'
    }
//other stuff
}

The problem

IE<=8 simply doesn't have an indexOf() method for arrays.

The solution

If you need indexOf in IE<=8, you should consider using the following polyfill, which is recommended at the MDN :

if (!Array.prototype.indexOf) {
    Array.prototype.indexOf = function(searchElement, fromIndex) {
        var k;
        if (this == null) {
            throw new TypeError('"this" is null or not defined');
        }
        var o = Object(this);
        var len = o.length >>> 0;
        if (len === 0) {
            return -1;
        }
        var n = +fromIndex || 0;
        if (Math.abs(n) === Infinity) {
            n = 0;
        }
        if (n >= len) {
            return -1;
        }
        k = Math.max(n >= 0 ? n : len - Math.abs(n), 0);
        while (k < len) {
            if (k in o && o[k] === searchElement) {
                return k;
            }
            k++;
        }
        return -1;
    };
}

Minified :

Array.prototype.indexOf||(Array.prototype.indexOf=function(r,t){var n;if(null==this)throw new TypeError('"this" is null or not defined');var e=Object(this),i=e.length>>>0;if(0===i)return-1;var a=+t||0;if(Math.abs(a)===1/0&&(a=0),a>=i)return-1;for(n=Math.max(a>=0?a:i-Math.abs(a),0);i>n;){if(n in e&&e[n]===r)return n;n++}return-1});

You have to merge your files first. Do a git status to see what are the files that need to be merged (means you need to resolve the conflicts first). Once this is done, do git add file_merged and do your pull again.

class func uuid(completionHandler: @escaping (String) -> ()) {
    if let uuid = UIDevice.current.identifierForVendor?.uuidString {
        completionHandler(uuid)
    }
    else {
        // If the value is nil, wait and get the value again later. This happens, for example, after the device has been restarted but before the user has unlocked the device.
        // https://developer.apple.com/documentation/uikit/uidevice/1620059-identifierforvendor?language=objc
        DispatchQueue.main.asyncAfter(deadline: .now() + 1.0) {
            uuid(completionHandler: completionHandler)
        }
    }
}

If all above methods fails use something like this:

    import React, { Component } from 'react';
    import { Redirect } from "react-router";
    
    export default class Reedirect extends Component {
        state = {
            redirect: false
        }
        redirectHandler = () => {
            this.setState({ redirect: true })
            this.renderRedirect();
        }
        renderRedirect = () => {
            if (this.state.redirect) {
                return <Redirect to='/' />
            }
        }
        render() {
            return (
                <>
                    <button onClick={this.redirectHandler}>click me</button>
                    {this.renderRedirect()}
                </>
            )
        }
    }

First, you have to locate the project directory in cmd After this fire below command and 'first_laravel_app' is the project name you can replace it with your own project name.

composer create-project laravel/laravel first_laravel_app --prefer-dist

You'll have to make a join:

SELECT A.SalesOrderID, B.Foo
FROM A
JOIN B bo ON bo.id = (
     SELECT TOP 1 id
     FROM B bi
     WHERE bi.SalesOrderID = a.SalesOrderID
     ORDER BY bi.whatever
     )
WHERE A.Date BETWEEN '2000-1-4' AND '2010-1-4'

, assuming that b.id is a PRIMARY KEY on B

In MS SQL 2005 and higher you may use this syntax:

SELECT SalesOrderID, Foo
FROM (
  SELECT A.SalesOrderId, B.Foo,
         ROW_NUMBER() OVER (PARTITION BY B.SalesOrderId ORDER BY B.whatever) AS rn
  FROM A
  JOIN B ON B.SalesOrderID = A.SalesOrderID
  WHERE A.Date BETWEEN '2000-1-4' AND '2010-1-4'
) i
WHERE rn

This will select exactly one record from B for each SalesOrderId.

You can use RawGit:
https://rawgit.com/necolas/css3-social-signin-buttons/master/index.html

It works better (at the time of this writing) than http://htmlpreview.github.com/, serving files with proper Content-Type headers. Additionally, it also provides CDN URL for use in production.

You need to stringify the json, not calling toString

var buf = Buffer.from(JSON.stringify(obj));

And for converting string to json obj :

var temp = JSON.parse(buf.toString());

After adding files to the stage, you need to commit them with git commit -m "comment" after git add .. Finally, to push them to a remote repository, you need to git push <remote_repo> <local_branch>.

onCreate(Bundle savedInstanceState) you will get the Bundle null when activity get starts first time and it will get in use when activity orientation get changed .......

http://www.gitshah.com/2011/03/how-to-handle-screen-orientation_28.html

Android provides another elegant way of achieving this. To achieve this, we have to override a method called onSaveInstanceState(). Android platform allows the users to save any instance state. Instance state can be saved in the Bundle. Bundle is passed as argument to the onSaveInstanceState method.

we can load the saved instance state from the Bundle passed as argument to the onCreate method. We can also load the saved instance state in onRestoreInstanceState method. But I will leave that for the readers to figure out.

.foo {
   position : relative;
}
.foo .wrapper {
    background-image : url('semi-trans.png');
    z-index : 10;
    position : absolute;
    top : 0;
    left : 0;
}

<div class="foo">
   <img src="example.png" />
   <div class="wrapper">&nbsp;</div>
</div>

The encoding for the page is not set correctly. Either add a header

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

or use set the appropriate http header.

Content-Type:text/html; charset=UTF-8

Firefox also allows you to change the encoding in View -> Character encoding.

If that's ok, I think javascript should handle UTF8 just fine.

app.all('*', function(req, res,next) {

        res.send(200);
    }
    else {

If you have already installed git , you can update the git with the command git update-git-for-windows

to know the current version use git --version

you can run this commands in cmd prompt

Looking back at the original question, we need to find some given keywords in a given sentence, count the number of occurrences and know something about where. I don't quite understand what "where" means (is it an index in the sentence?), so I'll pass that one... I'm still learning java, one step at a time, so I'll see to that one in due time :-)

It must be noticed that common sentences (as the one in the original question) can have repeated keywords, therefore the search cannot just ask if a given keyword "exists or not" and count it as 1 if it does exist. There can be more then one of the same. For example:

// Base sentence (added punctuation, to make it more interesting):
String sentence = "Say that 123 of us will come by and meet you, "
                + "say, at the woods of 123woods.";

// Split it (punctuation taken in consideration, as well):
java.util.List<String> strings = 
                       java.util.Arrays.asList(sentence.split(" |,|\\."));

// My keywords:
java.util.ArrayList<String> keywords = new java.util.ArrayList<>();
keywords.add("123woods");
keywords.add("come");
keywords.add("you");
keywords.add("say");

By looking at it, the expected result would be 5 for "Say" + "come" + "you" + "say" + "123woods", counting "say" twice if we go lowercase. If we don't, then the count should be 4, "Say" being excluded and "say" included. Fine. My suggestion is:

// Set... ready...?
int counter = 0;

// Go!
for(String s : strings)
{
    // Asking if the sentence exists in the keywords, not the other
    // around, to find repeated keywords in the sentence.
    Boolean found = keywords.contains(s.toLowerCase());
    if(found)
    {
        counter ++;
        System.out.println("Found: " + s);
    }
}

// Statistics:
if (counter > 0)
{
    System.out.println("In sentence: " + sentence + "\n"
                     + "Count: " + counter);
}

And the results are:

Found: Say
Found: come
Found: you
Found: say
Found: 123woods
In sentence: Say that 123 of us will come by and meet you, say, at the woods of 123woods.
Count: 5

Try this:

$Wsdl = 'http://xxxx.xxx.xx/webservice3.asmx?WSDL';
libxml_disable_entity_loader(false); //adding this worked for me
$Client = new SoapClient($Wsdl);
//Code...

What you have should work. It depends on the type of data you are setting i.e. if it's a string value you need to make sure it's in quotes e.g.

var val = '@ViewBag.ForSection';

If it's an integer you need to parse it as one i.e.

var val = parseInt(@ViewBag.ForSection);

With the code in the question, you're only dealing interacting with the first of the four entries returned by that selector.

Code below as a fiddle: https://jsfiddle.net/c4nhpqgb/

I want to be overly clear that you have four items that matched that selector, so you need to deal with each explicitly. Using eq() is a little more explicit making this point than the answers using map, though map or each is what you'd probably use "in real life" (jquery docs for eq here).

<html>
    <head>
        <script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" ></script>
    </head>

    <body>
        <div class="mbox">Block One</div>
        <div class="mbox">Block Two</div>
        <div class="mbox">Block Three</div>
        <div class="mbox">Block Four</div>

        <div id="outige"></div>
        <script>
            // using the $ prefix to use the "jQuery wrapped var" convention
            var i, $mvar = $('.mbox');

            // convenience method to display unprocessed html on the same page
            function logit( string )
            {
                var text = document.createTextNode( string );
                $('#outige').append(text);
                $('#outige').append("<br>");
            }

            logit($mvar.length);

            for (i=0; i<$mvar.length; i++)    {
                logit($mvar.eq(i).html());
            }
        </script>
    </body>

</html>

Output from logit calls (after the initial four div's display):

4
Block One
Block Two
Block Three
Block Four

According to the API

totalMemory()

Returns the total amount of memory in the Java virtual machine. The value returned by this method may vary over time, depending on the host environment. Note that the amount of memory required to hold an object of any given type may be implementation-dependent.

maxMemory()

Returns the maximum amount of memory that the Java virtual machine will attempt to use. If there is no inherent limit then the value Long.MAX_VALUE will be returned.

freeMemory()

Returns the amount of free memory in the Java Virtual Machine. Calling the gc method may result in increasing the value returned by freeMemory.

In reference to your question, maxMemory() returns the -Xmx value.

You may be wondering why there is a totalMemory() AND a maxMemory(). The answer is that the JVM allocates memory lazily. Lets say you start your Java process as such:

java -Xms64m -Xmx1024m Foo

Your process starts with 64mb of memory, and if and when it needs more (up to 1024m), it will allocate memory. totalMemory() corresponds to the amount of memory currently available to the JVM for Foo. If the JVM needs more memory, it will lazily allocate it up to the maximum memory. If you run with -Xms1024m -Xmx1024m, the value you get from totalMemory() and maxMemory() will be equal.

Also, if you want to accurately calculate the amount of used memory, you do so with the following calculation :

final long usedMem = totalMemory() - freeMemory();

os.system is equivalent to Unix system command, while subprocess was a helper module created to provide many of the facilities provided by the Popen commands with an easier and controllable interface. Those were designed similar to the Unix Popen command.

system() executes a command specified in command by calling /bin/sh -c command, and returns after the command has been completed

Whereas:

The popen() function opens a process by creating a pipe, forking, and invoking the shell.

If you are thinking which one to use, then use subprocess definitely because you have all the facilities for execution, plus additional control over the process.

The name of the DOM function is actually getElementsByClassName, not getElementByClassName, simply because more than one element on the page can have the same class, hence: Elements.

The return value of this will be a NodeList instance, or a superset of the NodeList (FF, for instance returns an instance of HTMLCollection). At any rate: the return value is an array-like object:

var y = document.getElementsByClassName('foo');
var aNode = y[0];

If, for some reason you need the return object as an array, you can do that easily, because of its magic length property:

var arrFromList = Array.prototype.slice.call(y);
//or as per AntonB's comment:
var arrFromList = [].slice.call(y);

As yckart suggested querySelector('.foo') and querySelectorAll('.foo') would be preferable, though, as they are, indeed, better supported (93.99% vs 87.24%), according to caniuse.com:

• querySelector(all)
• getElementsByClassName
• Don't use w3schools to learn something
• Refer to MDN for accurate information

In your case height will be calculated automatically, so you have to provide the height
use this

.list-content{
  width: 100%;
  height:150px;
}

Here is an solution that allows both prototype and function options.

// --------------------------------------------------------------------
// Add prototype for 'String.format' which is c# equivalent
//
// String.format("{0} i{2}a night{1}", "This", "mare", "s ");
// "{0} i{2}a night{1}".format("This", "mare", "s ");
// --------------------------------------------------------------------

if(!String.format)
    String.format = function(){
        for (var i = 0, args = arguments; i < args.length - 1; i++)
            args[0] = args[0].replace("{" + i + "}", args[i + 1]);
        return args[0];
    };
if(!String.prototype.format && String.format)
    String.prototype.format = function(){
        var args = Array.prototype.slice.call(arguments).reverse();
        args.push(this);
        return String.format.apply(this, args.reverse())
    };

Enjoy.

If you are using Eclipse... I renamed my main class file and got that error. I went to "Run As" configurator and under the class path for that project, it had listed both files in the class path. I removed old class that I renamed and left the class that had the new name and it compiled and ran just fine.

Say the remote is origin and the branch is master, and say you already have master checked out, might try the following:

git fetch origin
git reset --hard origin/master

This basically just takes the current branch and points it to the HEAD of the remote branch.

WARNING: As stated in the comments, this will throw away your local changes and overwrite with whatever is on the origin.

Or you can use the plumbing commands to do essentially the same:

git fetch <remote>
git update-ref refs/heads/<branch> $(git rev-parse <remote>/<branch>)
git reset --hard

EDIT: I'd like to briefly explain why this works.

The .git folder can hold the commits for any number of repositories. Since the commit hash is actually a verification method for the contents of the commit, and not just a randomly generated value, it is used to match commit sets between repositories.

A branch is just a named pointer to a given hash. Here's an example set:

$ find .git/refs -type f
.git/refs/tags/v3.8
.git/refs/heads/master
.git/refs/remotes/origin/HEAD
.git/refs/remotes/origin/master

Each of these files contains a hash pointing to a commit:

$ cat .git/refs/remotes/origin/master
d895cb1af15c04c522a25c79cc429076987c089b

These are all for the internal git storage mechanism, and work independently of the working directory. By doing the following:

git reset --hard origin/master

git will point the current branch at the same hash value that origin/master points to. Then it forcefully changes the working directory to match the file structure/contents at that hash.

To see this at work go ahead and try out the following:

git checkout -b test-branch
# see current commit and diff by the following
git show HEAD
# now point to another location
git reset --hard <remote>/<branch>
# see the changes again
git show HEAD

Here's my solution to this type of problem:

Create a new class in CSS and position off screen. Then put your alt text in HTML right before the property that calls your background image. Can be any tag, H1, H2, p, etc.

CSS

<style type="text/css">
  .offleft {
    margin-left: -9000px;
    position: absolute;
  }
</style>

HTML

<h1 class="offleft">put your alt text here</h1>
<div class or id that calls your bg image>  </div>

You can also create a public property.

// Using and namespace...

public partial class FormOptions : Form
{
    private string _MyString;    //  Use this
    public string MyString {     //  in 
      get { return _MyString; }  //  .NET
    }                            //  2.0

    public string MyString { get; } // In .NET 3.0 or newer

    // The rest of the form code
}

Then you can get it with:

FormOptions formOptions = new FormOptions();
formOptions.ShowDialog();

string myString = formOptions.MyString;

I encountered just the same problem when I wanted to store the dates in the DB as UTC and avoid using varchar and explicit String <-> java.util.Date conversions, or setting my whole Java app in the UTC time zone (because this could lead to another unexpected issues, if the JVM is shared across many applications).

So, there is an open source project DbAssist, which allows you to easily fix the read/write as UTC date from the database. Since you are using JPA Annotations to map the fields in the entity, all you have to do is to include the following dependency to your Maven pom file:

<dependency>
    <groupId>com.montrosesoftware</groupId>
    <artifactId>DbAssist-5.2.2</artifactId>
    <version>1.0-RELEASE</version>
</dependency>

Then you apply the fix (for Hibernate + Spring Boot example) by adding @EnableAutoConfiguration annotation before the Spring application class. For other setups installation instructions and more use examples, just refer to the project's github.

The good thing is that you don't have to modify the entities at all; you can leave their java.util.Date fields as they are.

5.2.2 has to correspond to the Hibernate version you are using. I am not sure, which version you are using in your project, but the full list of provided fixes is available on the wiki page of the project's github. The reason why the fix is different for various Hibernate versions is because Hibernate creators changed the API a couple of times between the releases.

Internally, the fix uses hints from divestoclimb, Shane and a few other sources in order to create a custom UtcDateType. Then it maps the standard java.util.Date with the custom UtcDateType which handles all the necessary time zone handling. The mapping of the types is achieved using @Typedef annotation in the provided package-info.java file.

@TypeDef(name = "UtcDateType", defaultForType = Date.class, typeClass = UtcDateType.class),
package com.montrosesoftware.dbassist.types;

You can find an article here which explains why such a time shift occurs at all and what are the approaches to solve it.

Both commands are correct :

mvn clean install -Pdev1
mvn clean install -P dev1

The problem is most likely not profile activation, but the profile not accomplishing what you expect it to.

It is normal that the command :

mvn help:active-profiles

does not display the profile, because is does not contain -Pdev1. You could add it to make the profile appear, but it would be pointless because you would be testing maven itself.

What you should do is check the profile behavior by doing the following :

1. set activeByDefault to true in the profile configuration,
2. run mvn help:active-profiles (to make sure it is effectively activated even without -Pdev1),
3. run mvn install.

It should give the same results as before, and therefore confirm that the problem is the profile not doing what you expect.

If it's WebKit-only, you can use <hr> to create a real separator.

Update with Spring Boot 2.2.2.Release.

Full example here, https://www.surasint.com/spring-boot-override-property-example/

Assume that, in your jar file, you have the application.properties which have these two line:

server.servlet.context-path=/test
server.port=8081

Then, in production, you want to override the server.port=8888 but you don't want to override the other properties.

First you create another file, ex override.properties and have online this line:

server.port=8888

Then you can start the jar like this

java -jar spring-boot-1.0-SNAPSHOT.jar --spring.config.location=classpath:application.properties,/opt/somewhere/override.properties

It sounds like your response is being evaluated somehow. This gives the same error in Chrome:

var resp = '{"votes":47,"totalvotes":90}';
eval(resp);

This is due to the braces '{...}' being interpreted by javascript as a code block and not an object literal as one might expect.

I would look at the JSON.decode() function and see if there is an eval in there.

Similar issue here: Eval() = Unexpected token : error

if your intention is send the full array from the html to the controller, can use this:

from the blade.php:

 <input type="hidden" name="quotation" value="{{ json_encode($quotation,TRUE)}}"> 

in controller

    public function Get(Request $req) {

    $quotation = array('quotation' => json_decode($req->quotation));

    //or

    return view('quotation')->with('quotation',json_decode($req->quotation))


}

pack_forget and grid_forget will only remove widgets from view, it doesn't destroy them. If you don't plan on re-using the widgets, your only real choice is to destroy them with the destroy method.

To do that you have two choices: destroy each one individually, or destroy the frame which will cause all of its children to be destroyed. The latter is generally the easiest and most effective.

Since you claim you don't want to destroy the container frame, create a secondary frame. Have this secondary frame be the container for all the widgets you want to delete, and then put this one frame inside the parent you do not want to destroy. Then, it's just a matter of destroying this one frame and all of the interior widgets will be destroyed along with it.

Use DateDiff with MINUTE difference:

don't forgot to add jQuery library

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.0/jquery.min.js"></script>

You usually don't want to, because there is an exponential number of them in nontrivial graphs; if you really want to get all (simple) paths, or all (simple) cycles, you just find one (by walking the graph), then backtrack to another.

I think it is because % has often be associated with the modulus operator in many programming languages.

It is the case, e.g., in C, C++, C# and Java, and many other languages which derive their syntax from C (C itself took it from B).

OPcache replaces APC

Because OPcache is designed to replace the APC module, it is not possible to run them in parallel in PHP. This is fine for caching PHP opcode as neither affects how you write code.

However it means that if you are currently using APC to store other data (through the apc_store() function) you will not be able to do that if you decide to use OPCache.

You will need to use another library such as either APCu or Yac which both store data in shared PHP memory, or switch to use something like memcached, which stores data in memory in a separate process to PHP.

Also, OPcache has no equivalent of the upload progress meter present in APC. Instead you should use the Session Upload Progress.

Settings for OPcache

The documentation for OPcache can be found here with all of the configuration options listed here. The recommended settings are:

; Sets how much memory to use
opcache.memory_consumption=128

;Sets how much memory should be used by OPcache for storing internal strings 
;(e.g. classnames and the files they are contained in)
opcache.interned_strings_buffer=8

; The maximum number of files OPcache will cache
opcache.max_accelerated_files=4000

;How often (in seconds) to check file timestamps for changes to the shared
;memory storage allocation.
opcache.revalidate_freq=60

;If enabled, a fast shutdown sequence is used for the accelerated code
;The fast shutdown sequence doesn't free each allocated block, but lets
;the Zend Engine Memory Manager do the work.
opcache.fast_shutdown=1

;Enables the OPcache for the CLI version of PHP.
opcache.enable_cli=1

If you use any library or code that uses code annotations you must enable save comments:

opcache.save_comments=1

If disabled, all PHPDoc comments are dropped from the code to reduce the size of the optimized code. Disabling "Doc Comments" may break some existing applications and frameworks (e.g. Doctrine, ZF2, PHPUnit)

I arrived here like most people with this same issue, and left shocked that none of the answer even remotely worked.

For anyone interested, here is the actual solution:

... //rest of options
width: '100%',
height: '350',
chartArea:{
    left:5,
    top: 20,
    width: '100%',
    height: '350',
}
... //rest of options

The key here has nothing to do with the "left" or "top" values. But rather that the:

Dimensions of both the chart and chart-area are SET and set to the SAME VALUE

As an amendment to my answer. The above will indeed solve the "excessive" padding/margin/whitespace problem. However, if you wish to include axes labels and/or a legend you will need to reduce the height & width of the chart area so something slightly below the outer width/height. This will "tell" the chart API that there is sufficient room to display these properties. Otherwise it will happily exclude them.

s = s.length() > 10 ? s.substring(0, 9) : s;

In case you happen to be on Android and you are not using Jack yet (e.g. because it's still lacking support for Instant Run), and if you want more control over formatting of the resulting string (e.g. you would like to use the newline character as the divider of elements), and happen to use/want to use the StreamSupport library (for using streams on Java 7 or earlier versions of the compiler), you could use something like this (I put this method in my ListUtils class):

public static <T> String asString(List<T> list) {
    return StreamSupport.stream(list)
            .map(Object::toString)
            .collect(Collectors.joining("\n"));
}

And of course, make sure to implement toString() on your list objects' class.

The InputFilter I came up with allows you to configure the number of digits before and after the decimal place. Additionally, it disallows leading zeroes.

public class DecimalDigitsInputFilter implements InputFilter
{
    Pattern pattern;

    public DecimalDigitsInputFilter(int digitsBeforeDecimal, int digitsAfterDecimal)
    {
        pattern = Pattern.compile("(([1-9]{1}[0-9]{0," + (digitsBeforeDecimal - 1) + "})?||[0]{1})((\\.[0-9]{0," + digitsAfterDecimal + "})?)||(\\.)?");
    }

    @Override public CharSequence filter(CharSequence source, int sourceStart, int sourceEnd, Spanned destination, int destinationStart, int destinationEnd)
    {
        // Remove the string out of destination that is to be replaced.
        String newString = destination.toString().substring(0, destinationStart) + destination.toString().substring(destinationEnd, destination.toString().length());

        // Add the new string in.
        newString = newString.substring(0, destinationStart) + source.toString() + newString.substring(destinationStart, newString.length());

        // Now check if the new string is valid.
        Matcher matcher = pattern.matcher(newString);

        if(matcher.matches())
        {
            // Returning null indicates that the input is valid.
            return null;
        }

        // Returning the empty string indicates the input is invalid.
        return "";
    }
}

// To use this InputFilter, attach it to your EditText like so:
final EditText editText = (EditText) findViewById(R.id.editText);

EditText.setFilters(new InputFilter[]{new DecimalDigitsInputFilter(4, 4)});

You aren't building your formula right.

Worksheets("EmployeeCosts").Range("B" & var1a).Formula =  "=SUM(H5:H" & var1a & ")"

This does the same as the following lines do:

Dim myFormula As String
myFormula = "=SUM(H5:H"
myFormula = myFormula & var1a
myformula = myformula & ")"

which is what you are trying to do.

Also, you want to have the = at the beginning of the formala.

Kind of a roundabout solution but I just call the API endpoint for my lambda functions when I need to chain them. This allows you to decide while coding if you want them to be asynchronous or not.

In case you don't want to setup a POST request you can just setup a simple GET request with a couple, or none at all, query string parameters for easy event passing.

Try this macro to test the overflow bit of 32-bit machines (adapted the solution of Angel Sinigersky)

#define overflowflag(isOverflow){   \
size_t eflags;                      \
asm ("pushfl ;"                     \
     "pop %%eax"                    \
    : "=a" (eflags));               \
isOverflow = (eflags >> 11) & 1;}

I defined it as a macro because otherwise the overflow bit would have been overwritten.

Subsequent is a little application with the code segement above:

#include <cstddef>
#include <stdio.h>
#include <iostream>
#include <conio.h>
#if defined( _MSC_VER )
#include <intrin.h>
#include <oskit/x86>
#endif

using namespace std;

#define detectOverflow(isOverflow){     \
size_t eflags;                      \
asm ("pushfl ;"                     \
    "pop %%eax"                     \
    : "=a" (eflags));               \
isOverflow = (eflags >> 11) & 1;}

int main(int argc, char **argv) {

    bool endTest = false;
    bool isOverflow;

    do {
        cout << "Enter two intergers" << endl;
        int x = 0;
        int y = 0;
        cin.clear();
        cin >> x >> y;
        int z = x * y;
        detectOverflow(isOverflow)
        printf("\nThe result is: %d", z);
        if (!isOverflow) {
            std::cout << ": no overflow occured\n" << std::endl;
        } else {
            std::cout << ": overflow occured\n" << std::endl;
        }

        z = x * x * y;
        detectOverflow(isOverflow)
        printf("\nThe result is: %d", z);
        if (!isOverflow) {
            std::cout << ": no overflow ocurred\n" << std::endl;
        } else {
            std::cout << ": overflow occured\n" << std::endl;
        }

        cout << "Do you want to stop? (Enter \"y\" or \"Y)" << endl;

        char c = 0;

        do {
            c = getchar();
        } while ((c == '\n') && (c != EOF));

        if (c == 'y' || c == 'Y') {
            endTest = true;
        }

        do {
            c = getchar();
        } while ((c != '\n') && (c != EOF));

    } while (!endTest);
}

No, not all browsers support the sizes attribute:

• Safari: Yes, it picks the picture that fits best.
• Opera: Yes, it picks the picture that fits best.
• IE11: Not sure. It apparently takes the larger picture it finds, which is a bit crude but okay.
• Chrome: No, see bugs 112941 and 324820. In fact, Chrome tends to load all declared icons, not only the best/first/last one.
• Firefox: No, see bug 751712. Like Chrome, Firefox tends to load all declared icon.

Note that some platforms define specific sizes:

• Android Chrome expects a 192x192 icon, but it favors the icons declared in manifest.json if it is present. Plus, Chrome uses the Apple Touch icon for bookmarks.
• Coast by Opera expects a 228x228 icon.
• Google TV expects a 96x96 icon.

Here is a function that works with jQuery (for height only, not width):

function setHeight(jq_in){
    jq_in.each(function(index, elem){
        // This line will work with pure Javascript (taken from NicB's answer):
        elem.style.height = elem.scrollHeight+'px'; 
    });
}
setHeight($('<put selector here>'));

Note: The op asked for a solution that does not use Javascript, however this should be helpful to many people who come across this question.

TypeScript uses '<>' to surround casts, so the above becomes:

var script = <HTMLScriptElement>document.getElementsByName("script")[0];

However, unfortunately you cannot do:

var script = (<HTMLScriptElement[]>document.getElementsByName(id))[0];

You get the error

Cannot convert 'NodeList' to 'HTMLScriptElement[]'

But you can do :

(<HTMLScriptElement[]><any>document.getElementsByName(id))[0];

You can do it by setting the aspect of the image manually (or by letting it auto-scale to fill up the extent of the figure).

By default, imshow sets the aspect of the plot to 1, as this is often what people want for image data.

In your case, you can do something like:

import matplotlib.pyplot as plt
import numpy as np

grid = np.random.random((10,10))

fig, (ax1, ax2, ax3) = plt.subplots(nrows=3, figsize=(6,10))

ax1.imshow(grid, extent=[0,100,0,1])
ax1.set_title('Default')

ax2.imshow(grid, extent=[0,100,0,1], aspect='auto')
ax2.set_title('Auto-scaled Aspect')

ax3.imshow(grid, extent=[0,100,0,1], aspect=100)
ax3.set_title('Manually Set Aspect')

plt.tight_layout()
plt.show()

Since you've already stashed your changes, all you need is this one-liner:

• git stash branch <branchname> [<stash>]

From the docs (https://www.kernel.org/pub/software/scm/git/docs/git-stash.html):

Creates and checks out a new branch named <branchname> starting from the commit at which the <stash> was originally created, applies the changes recorded in <stash> to the new working tree and index. If that succeeds, and <stash> is a reference of the form stash@{<revision>}, it then drops the <stash>. When no <stash> is given, applies the latest one.

This is useful if the branch on which you ran git stash save has changed enough that git stash apply fails due to conflicts. Since the stash is applied on top of the commit that was HEAD at the time git stash was run, it restores the originally stashed state with no conflicts.

You'll need to get a compiler. The easiest way is probably to install XCode development environment from the CDs/DVDs you got with your Mac, which will give you gcc. Then you should be able compile it like

gcc -o mybinaryfile mysourcefile.c

I was getting the same error on my Ubuntu 16.04 (Linux 4.14 kernel) in Google Compute Engine with K80 GPU. I upgraded the kernel to 4.15 from 4.14 and boom the problem was solved. Here is how I upgraded my Linux kernel from 4.14 to 4.15:

Step 1:
Check the existing kernel of your Ubuntu Linux:

uname -a

Step 2:

Ubuntu maintains a website for all the versions of kernel that have 
been released. At the time of this writing, the latest stable release 
of Ubuntu kernel is 4.15. If you go to this 
link: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15/, you will 
see several links for download.

Step 3:

Download the appropriate files based on the type of OS you have. For 64 
bit, I would download the following deb files:

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15/linux-headers-
4.15.0-041500_4.15.0-041500.201802011154_all.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15/linux-headers-
4.15.0-041500-generic_4.15.0-041500.201802011154_amd64.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15/linux-image-
4.15.0-041500-generic_4.15.0-041500.201802011154_amd64.deb

Step 4:

Install all the downloaded deb files:

sudo dpkg -i *.deb

Step 5:
Reboot your machine and check if the kernel has been updated by:
uname -a

You should see that your kernel has been upgraded and hopefully nvidia-smi should work.

onload event it only supports with few tags like listed below.

<body>, <frame>, <iframe>, <img>, <input type="image">, <link>, <script>, <style>

Here the reference for onload event

EditText number1 = (EditText) layout.findViewById(R.id.edittext); 
number1.setInputType(InputType.TYPE_CLASS_NUMBER);

To register a comm .dll or .ocx on Windows 7 32-bit, do the following:

Copy .dll or .ocx to c:\windows\system32 Type cmd in Run menu, it will search cmd.exe, right click and click Run as Administrator

It will show a prompt at c:\windows\system32

Type

regsvr32 ocxname.ocx to register .ocx

or

type regsvr32 dllname.dll to register .dll

if we use the system given action bar following code works fine

getActionBar().setHomeButtonEnabled(true);

@Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {

    int itemId = item.getItemId();
    switch (itemId) {
    case android.R.id.home:
      //do your action here.
        break;

    }

    return true;
}

The modern way is to use ParentNode.append(), like so:

let element = document.createElement('div');_x000D_
element.style.cssText = 'position:absolute;width:100%;height:100%;opacity:0.3;z-index:100;background:#000;';_x000D_
document.body.append(element);

I had to setup all 4 things in .gitconfig with:

git config --global http.sslVerify false
git config --global https.sslVerify false
git config --global http.proxy http://user:pass@yourproxy:port
git config --global https.proxy http://user:pass@yourproxy:port

Only then the cloning was successful.

STATICFILES_DIRS: You can keep the static files for your project here e.g. the ones used by your templates.

STATIC_ROOT: leave this empty, when you do manage.py collectstatic, it will search for all the static files on your system and move them here. Your static file server is supposed to be mapped to this folder wherever it is located. Check it after running collectstatic and you'll find the directory structure django has built.

--------Edit----------------

As pointed out by @DarkCygnus, STATIC_ROOT should point at a directory on your filesystem, the folder should be empty since it will be populated by Django.

STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')

or

STATIC_ROOT = '/opt/web/project/static_files'

--------End Edit -----------------

STATIC_URL: '/static/' is usually fine, it's just a prefix for static files.

You can use an anonymous function to pass the matches to your function:

$result = preg_replace_callback(
    "/\{([<>])([a-zA-Z0-9_]*)(\?{0,1})([a-zA-Z0-9_]*)\}(.*)\{\\1\/\\2\}/isU",
    function($m) { return CallFunction($m[1], $m[2], $m[3], $m[4], $m[5]); },
    $result
);

Apart from being faster, this will also properly handle double quotes in your string. Your current code using /e would convert a double quote " into \".

Such difference between the output of du -sh and df -h may happen if some large file has been deleted, but is still opened by some process. Check with the command lsof | grep deleted to see which processes have opened descriptors to deleted files. You can restart the process and the space will be freed.

An actual JSON request would look like this:

data: '{"command":"on"}',

Where you're sending an actual JSON string. For a more general solution, use JSON.stringify() to serialize an object to JSON, like this:

data: JSON.stringify({ "command": "on" }),

To support older browsers that don't have the JSON object, use json2.js which will add it in.

What's currently happening is since you have processData: false, it's basically sending this: ({"command":"on"}).toString() which is [object Object]...what you see in your request.

This is not possible to do with a textarea. What you are looking for is an content editable div, which is very easily done:

<div contenteditable="true"></div>

jsFiddle

div.editable {_x000D_
    width: 300px;_x000D_
    height: 200px;_x000D_
    border: 1px solid #ccc;_x000D_
    padding: 5px;_x000D_
}_x000D_
_x000D_
strong {_x000D_
  font-weight: bold;_x000D_
}

<div contenteditable="true">This is the first line.<br>_x000D_
See, how the text fits here, also if<br>there is a <strong>linebreak</strong> at the end?_x000D_
<br>It works nicely._x000D_
<br>_x000D_
<br><span style="color: lightgreen">Great</span>._x000D_
</div>

A very very good document regarding this topic is Troubleshooting Guide for Java from (originally) Sun. See the chapter "Troubleshooting System Crashes" for information about hs_err_pid* Files.

See Appendix C - Fatal Error Log

Per the guide, by default the file will be created in the working directory of the process if possible, or in the system temporary directory otherwise. A specific location can be chosen by passing in the -XX:ErrorFile product flag. It says:

If the -XX:ErrorFile= file flag is not specified, the system attempts to create the file in the working directory of the process. In the event that the file cannot be created in the working directory (insufficient space, permission problem, or other issue), the file is created in the temporary directory for the operating system.

Considering you want to check for ASCII Alphanumeric characters, Try this: "^[a-zA-Z0-9]*$". Use this RegEx in String.matches(Regex), it will return true if the string is alphanumeric, else it will return false.

public boolean isAlphaNumeric(String s){
    String pattern= "^[a-zA-Z0-9]*$";
    return s.matches(pattern);
}

If it will help, read this for more details about regex: http://www.vogella.com/articles/JavaRegularExpressions/article.html

I think you face three problems:

1. understanding the FileChooser
2. writing/reading files
3. understanding extensions and file formats

ad 1. Are you sure you've connected the FileChooser to a correct panel/container? I'd go for a simple tutorial on this matter and see if it works. That's the best way to learn - by making small but large enough steps forward. Breaking down an issue into such parts might be tricky sometimes ;)

ad. 2. After you save or open the file you should have methods to write or read the file. And again there are pretty neat examples on this matter and it's easy to understand topic.

ad. 3. There's a difference between a file having extension and file format. You can change the format of any file to anything you want but that doesn't affect it's contents. It might just render the file unreadable for the application associated with such extension. TXT files are easy - you read what you write. XLS, DOCX etc. require more work and usually framework is the best way to tackle these.

Pointers:

• Can be assigned nullptr (or NULL).
• At the call site, you must use & if your type is not a pointer itself, making explicitly you are modifying your object.
• Pointers can be rebound.

References:

• Cannot be null.
• Once bound, cannot change.
• Callers don't need to explicitly use &. This is considered sometimes bad because you must go to the implementation of the function to see if your parameter is modified.

Would you please try with below code block, which is exactly what you're looking for:

SqlConnection conn = new SqlConnection
{
    ConnectionString = "Data Source=" + System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase) + "\\Database.sdf"
};

Solution is to make JAVA_HOME == dir above bin where javac lives as in

type javac

javac is /usr/bin/javac   # now check if its just a symlink

ls -la /usr/bin/javac 

/usr/bin/javac -> /etc/alternatives/javac   # its a symlink so check again

ls -la /etc/alternatives/javac  # now check if its just a symlink

/etc/alternatives/javac -> /usr/lib/jvm/java-8-openjdk-amd64/bin/javac

OK so finally found the bin above actual javac so do this

export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
export PATH=$JAVA_HOME/bin:$PATH

above can be simplified and generalized to

which javac >/dev/null 2>&1 || die "ERROR: no 'javac' command could be found in your PATH"
export JAVA_HOME=$(dirname $(dirname $(readlink -f $(which javac)  )))

The other solutions here all have caveats (though they address the question at hand). If you are (1) looping over mixed-types or (2) want a generic solution that you can export as a function or include in your utilities, none of the other solutions here will work.

The simplest and most self-explanatory solution is:

// simplest, most-readable
if (is_bool($res) {
    $res = $res ? 'true' : 'false';
}

// same as above but written more tersely
$res = is_bool($res) ? ($res ? 'true' : 'false') : $res;

// Terser still, but completely unnecessary  function call and must be
// commented due to poor readability. What is var_export? What is its
// second arg? Why are we exporting stuff?
$res = is_bool($res) ? var_export($res, 1) : $res;

But most developers reading your code will require a trip to http://php.net/var_export to understand what the var_export does and what the second param is.

1. var_export

Works for boolean input but converts everything else to a string as well.

// OK
var_export(false, 1); // 'false'
// OK
var_export(true, 1);  // 'true'
// NOT OK
var_export('', 1);  // '\'\''
// NOT OK
var_export(1, 1);  // '1'

2. ($res) ? 'true' : 'false';

Works for boolean input but converts everything else (ints, strings) to true/false.

// OK
true ? 'true' : 'false' // 'true'
// OK
false ? 'true' : 'false' // 'false'
// NOT OK
'' ? 'true' : 'false' // 'false'
// NOT OK
0 ? 'true' : 'false' // 'false'

3. json_encode()

Same issues as var_export and probably worse since json_encode cannot know if the string true was intended a string or a boolean.

You could create a function that checks every input in an input class like below

 function validateForm() {
  
    var anyFieldIsEmpty = jQuery(".myclass").filter(function () {
        return $.trim(this.value).length === 0;
    }).length > 0

    if (anyFieldIsEmpty) {
        alert("Fill all the necessary fields");
        var empty = $(".myclass").filter(function () {
            return $.trim(this.value).length === 0;
        })
        empty.css("border", "1px solid red");
        return false;
    } else {
        return true;
    }
}

What this does is it checks every input in 'myclass' and if empty it gives alert and colour the border of the input and user will recognize which input is not filled.

Perhaps something like this (untested code but should give you an idea)?

$new = array();

foreach ($array as $value)
{
    if (isset($new[$value]))
        $new[$value]++;
    else
        $new[$value] = 1;
}

Then you'll get a new array with the values as keys and their value is the number of times they existed in the original array.

Set line-height to the vertical size of the picture, then do vertical-align:middle like Josh said.

so if the picture is 20px, you would have

{
line-height:20px;
font-size:14px;
vertical-align:middle;
}

As of Bootstrap 3, you can use Panel classes:

<div class="panel panel-default">Surrounded by border</div>

In Bootstrap 4, you can use Border classes:

<div class="border border-secondary">Surrounded by border</div>

Why does this happen?

It seems this section on w3.org suggests that text-overflow applies only to block elements:

11.1.  Overflow Ellipsis: the ‘text-overflow’ property

text-overflow      clip | ellipsis | <string>  
Initial:           clip   
APPLIES TO:        BLOCK CONTAINERS               <<<<
Inherited:         no  
Percentages:       N/A  
Media:             visual  
Computed value:    as specified  

The MDN says the same.

This jsfiddle has your code (with a few debug modifications), which works fine if it's applied to a div instead of a td. It also has the only workaround I could quickly think of, by wrapping the contents of the td in a containing div block. However, that looks like "ugly" markup to me, so I'm hoping someone else has a better solution. The code to test this looks like this:

td, div {_x000D_
  overflow: hidden;_x000D_
  text-overflow: ellipsis;_x000D_
  white-space: nowrap;_x000D_
  border: 1px solid red;_x000D_
  width: 80px;_x000D_
}

Works, but no tables anymore:_x000D_
<div>Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah.</div>_x000D_
_x000D_
Works, but non-semantic markup required:_x000D_
<table><tr><td><div>Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah.</div></td></tr></table>

I wrote my thoughts of static classes in an earlier Stack Overflow answer: Class with single method -- best approach?

I used to love utility classes filled up with static methods. They made a great consolidation of helper methods that would otherwise lie around causing redundancy and maintenance hell. They're very easy to use, no instantiation, no disposal, just fire'n'forget. I guess this was my first unwitting attempt at creating a service-oriented architecture - lots of stateless services that just did their job and nothing else. As a system grows however, dragons be coming.

Polymorphism

Say we have the method UtilityClass.SomeMethod that happily buzzes along. Suddenly we need to change the functionality slightly. Most of the functionality is the same, but we have to change a couple of parts nonetheless. Had it not been a static method, we could make a derivate class and change the method contents as needed. As it's a static method, we can't. Sure, if we just need to add functionality either before or after the old method, we can create a new class and call the old one inside of it - but that's just gross.

Interface woes

Static methods cannot be defined through interfaces for logic reasons. And since we can't override static methods, static classes are useless when we need to pass them around by their interface. This renders us unable to use static classes as part of a strategy pattern. We might patch some issues up by passing delegates instead of interfaces.

Testing

This basically goes hand in hand with the interface woes mentioned above. As our ability of interchanging implementations is very limited, we'll also have trouble replacing production code with test code. Again, we can wrap them up, but it'll require us to change large parts of our code just to be able to accept wrappers instead of the actual objects.

Fosters blobs

As static methods are usually used as utility methods and utility methods usually will have different purposes, we'll quickly end up with a large class filled up with non-coherent functionality - ideally, each class should have a single purpose within the system. I'd much rather have a five times the classes as long as their purposes are well defined.

Parameter creep

To begin with, that little cute and innocent static method might take a single parameter. As functionality grows, a couple of new parameters are added. Soon further parameters are added that are optional, so we create overloads of the method (or just add default values, in languages that support them). Before long, we have a method that takes 10 parameters. Only the first three are really required, parameters 4-7 are optional. But if parameter 6 is specified, 7-9 are required to be filled in as well... Had we created a class with the single purpose of doing what this static method did, we could solve this by taking in the required parameters in the constructor, and allowing the user to set optional values through properties, or methods to set multiple interdependent values at the same time. Also, if a method has grown to this amount of complexity, it most likely needs to be in its own class anyway.

Demanding consumers to create an instance of classes for no reason

One of the most common arguments is: Why demand that consumers of our class create an instance for invoking this single method, while having no use for the instance afterwards? Creating an instance of a class is a very very cheap operation in most languages, so speed is not an issue. Adding an extra line of code to the consumer is a low cost for laying the foundation of a much more maintainable solution in the future. And finally, if you want to avoid creating instances, simply create a singleton wrapper of your class that allows for easy reuse - although this does make the requirement that your class is stateless. If it's not stateless, you can still create static wrapper methods that handle everything, while still giving you all the benefits in the long run. Finally, you could also make a class that hides the instantiation as if it was a singleton: MyWrapper.Instance is a property that just returns new MyClass();

Only a Sith deals in absolutes

Of course, there are exceptions to my dislike of static methods. True utility classes that do not pose any risk to bloat are excellent cases for static methods - System.Convert as an example. If your project is a one-off with no requirements for future maintenance, the overall architecture really isn't very important - static or non static, doesn't really matter - development speed does, however.

Standards, standards, standards!

Using instance methods does not inhibit you from also using static methods, and vice versa. As long as there's reasoning behind the differentiation and it's standardised. There's nothing worse than looking over a business layer sprawling with different implementation methods.

To use the tuple you need to do the following, in the view change the model to:

@model Tuple<Person,Order>

to use @html methods you need to do the following i.e:

@Html.DisplayNameFor(tuple => tuple.Item1.PersonId)

or

@Html.ActionLink("Edit", "Edit", new { id=Model.Item1.Id }) |

Item1 indicates the first parameter passed to the Tuple method and you can use Item2 to access the second model and so on.

in your controller you need to create a variable of type Tuple and then pass it to the view:

    public ActionResult Details(int id = 0)
    {
        Person person = db.Persons.Find(id);
        if (person == null)
        {
            return HttpNotFound();
        }
        var tuple = new Tuple<Person, Order>(person,new Order());

        return View(tuple);
    }

Another example : Multiple models in a view

Basically the same answer as here, but easy to copy/paste, and it just works ;-)

  import java.io.FileWriter;

  public void saveToFile(String data, String filename) {
    try (
      FileWriter fw = new FileWriter(filename)) {
      fw.write(data);
    } catch (Exception e) {
      throw new RuntimeException(e);
    }
  }

Controller as version (recommended)

Here the template

<div ng-app="example" ng-controller="myController as $ctrl">
    <input type="text" ng-model="$ctrl.searchText" />
    <button ng-click="$ctrl.check()">Check!</button>
    {{ $ctrl.searchText }}
</div>

The JS

angular.module('example', [])
  .controller('myController', function() {
    var vm = this;
    vm.check = function () {
      console.log(vm.searchText);
    };
  });

An example: http://codepen.io/Damax/pen/rjawoO

The best will be to use component with Angular 2.x or Angular 1.5 or upper

Old way (NOT recommended)

This is NOT recommended because a string is a primitive, highly recommended to use an object instead

Try this in your markup

<input type="text" ng-model="searchText" />
<button ng-click="check(searchText)">Check!</button>
{{ searchText }}

and this in your controller

$scope.check = function (searchText) {
    console.log(searchText);
}

this works for me

$("#values:input").attr("disabled",true);
$("#values:input").attr("disabled",false);

Alternatively, you can also delete a Foreign Key Constraint from the SQL Server Management Studio itself. You can try it if the commands do not work.

1. Expand your database view.
2. Right Click on Table which has foreign key constraint. Choose Design. A tab with the information about table columns will open.
3. Right click on the column which has the foreign key reference. Or you can right click on any column. Choose Relationships.
4. A list of relationships will appear (if you have one) in a pop up window.
5. From there you can delete the foreign key constraint.

I hope that helps

I had exactly the same problem, to solve it, you can do one of two things:

• Put all variables in System Variables instead of User and add the ones you want to PATH

Or

• Put all variables in User Variables, and create or edit the PATH variables in User Variable, not In System. The Path variables in System don't expand the User Variables.

If the above are all correct, but the problem is still present, you need to check the system Registry, in HKEY_CURRENT_USER\Environment, to make sure the "PATH" key type is REG_EXPAND_SZ (not REG_SZ).

use as at end of query

Select * into #temp (select * from table1,table2) as temp_table

You might run into this issue if you open a TS file that exists outside of the project. For instance, I'm using lerna and had a file open from another package. Although that other package had it's own tsconfig with experimental decorators, VsCode doesn't honor it.

I got the following error when using strict mode:

Node error: "Octal literals are not allowed in strict mode."

The following solution works (source):

process.stdout.write("received: " + bytesReceived + "\x1B[0G");

This a stab at creating a reusable column to comma separated string. In this case, I only one strings that have values and I do not want empty strings or nulls.

First I create a user defined type that is a one column table.

-- ================================
-- Create User-defined Table Type
-- ================================
USE [RSINET.MVC]
GO

-- Create the data type
CREATE TYPE [dbo].[SingleVarcharColumn] AS TABLE 
(
    data NVARCHAR(max)
)
GO

The real purpose of the type is to simplify creating a scalar function to put the column into comma separated values.

-- ================================================
-- Template generated from Template Explorer using:
-- Create Scalar Function (New Menu).SQL
--
-- Use the Specify Values for Template Parameters 
-- command (Ctrl-Shift-M) to fill in the parameter 
-- values below.
--
-- This block of comments will not be included in
-- the definition of the function.
-- ================================================
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
-- =============================================
-- Author:  Rob Peterson        
-- Create date: 8-26-2015
-- Description: This will take a single varchar column and convert it to
-- comma separated values.
-- =============================================
CREATE FUNCTION fnGetCommaSeparatedString 
(
    -- Add the parameters for the function here
    @column AS [dbo].[SingleVarcharColumn] READONLY
)
RETURNS VARCHAR(max)
AS
BEGIN
-- Declare the return variable here
DECLARE @result VARCHAR(MAX)
DECLARE @current VARCHAR(MAX)
DECLARE @counter INT
DECLARE @c CURSOR

SET @result = ''
SET @counter = 0
-- Add the T-SQL statements to compute the return value here
SET @c = CURSOR FAST_FORWARD
    FOR SELECT COALESCE(data,'') FROM @column
    OPEN @c
    FETCH NEXT FROM @c
    INTO @current
    WHILE @@FETCH_STATUS = 0
    BEGIN
        IF @result <> '' AND @current <> '' SET @result = @result + ',' + @current
        IF @result = '' AND @current <> '' SET @result = @current
    FETCH NEXT FROM @c
    INTO @current
    END
    CLOSE @c
    DEALLOCATE @c
-- Return the result of the function
RETURN @result

END
GO

Now, to use this. I select the column I want to convert to a comma separated string into the SingleVarcharColumn Type.

DECLARE @s as SingleVarcharColumn

INSERT INTO @s VALUES ('rob')
INSERT INTO @s VALUES ('paul')
INSERT INTO @s VALUES ('james')
INSERT INTO @s VALUES (null)


INSERT INTO @s
SELECT iClientID FROM [dbo].tClient

SELECT [dbo].fnGetCommaSeparatedString(@s)

To get results like this.

rob,paul,james,1,9,10,11,12,13,14,15,16,18,19,23,26,27,28,29,30,31,32,34,35,36,37,38,39,40,41,42,44,45,46,47,48,49,50,52,53,54,56,57,59,60,61,62,63,64,65,66,67,68,69,70,71,72,74,75,76,77,78,81,82,83,84,87,88,90,91,92,93,94,98,100,101,102,103,104,105,106,107,108,109,110,111,112,113,114,115,116,117,118,120,121,122,123,124,125,126,127,128,129,131,132,133,134,135,136,137,138,139,140,141,142,143,144,145,146,147,148,149,150,151,152,153,154,155,156,157,158,159

I made my data column in my SingleVarcharColumn type an NVARCHAR(MAX) which may hurt performance, but I flexibility was what I was looking for and it runs fast enough for my purposes. It would probably be faster if it were a varchar and if it had a fixed and smaller width, but I have not tested it.

You need to include xmlbeans-xxx.jar and if you have downloaded the POI binary zip, you will get the xmlbeans-xxx.jar in ooxml-lib folder (eg: \poi-3.11\ooxml-lib)

This jar is used for XML binding which is applicable for .xlsx files.

Funtional efficiency is totally different. If you would like to select only "return value" except duplicate one, use distinct is better than group by. Because "group by" include ( sorting + removing ) , "distinct" include ( removing )

Taken from this answer.

1. Close your packages.config file.
2. Build
3. Warning is gone!

This is the first time I see ignoring a problem actually makes it go away...

Edit in 2020: if you are viewing this warning, consider upgrading to PackageReference if you can

For anyone interested, I ran into this same issue when using css modules and react css modules.

Most components have an associated css module style, and in this example my Button has its own css file, as does the Promo parent component. But I want to pass some additional styles to Button from Promo

So the styleable Button looks like this:

Button.js

import React, { Component } from 'react'
import CSSModules from 'react-css-modules'
import styles from './Button.css'

class Button extends Component {

  render() {

    let button = null,
        className = ''

    if(this.props.className !== undefined){
        className = this.props.className
    }

    button = (
      <button className={className} styleName='button'>
        {this.props.children}
      </button>
    )

    return (
        button
    );
  }
};

export default CSSModules(Button, styles, {allowMultiple: true} )

In the above Button component the Button.css styles handle the common button styles. In this example just a .button class

Then in my component where I want to use the Button, and I also want to modify things like the position of the button, I can set extra styles in Promo.css and pass through as the className prop. In this example again called .button class. I could have called it anything e.g. promoButton.

Of course with css modules this class will be .Promo__button___2MVMD whereas the button one will be something like .Button__button___3972N

Promo.js

import React, { Component } from 'react';
import CSSModules from 'react-css-modules';
import styles from './Promo.css';

import Button from './Button/Button'

class Promo extends Component {

  render() {

    return (
        <div styleName='promo' >
          <h1>Testing the button</h1>
          <Button className={styles.button} >
            <span>Hello button</span>
          </Button>
        </div>
      </Block>
    );
  }
};

export default CSSModules(Promo, styles, {allowMultiple: true} );

Probably it is some message from your system.

Type in terminal:

man mail

, and see how can you get this message from your system.

Try:

tr -s ' ' <text.txt | cut -d ' ' -f4

From the tr man page:

-s, --squeeze-repeats   replace each input sequence of a repeated character
                        that is listed in SET1 with a single occurrence
                        of that character

Based on First answer here is the complete image selection options:

Filter = @"|All Image Files|*.BMP;*.bmp;*.JPG;*.JPEG*.jpg;*.jpeg;*.PNG;*.png;*.GIF;*.gif;*.tif;*.tiff;*.ico;*.ICO
           |PNG|*.PNG;*.png
           |JPEG|*.JPG;*.JPEG*.jpg;*.jpeg
           |Bitmap(.BMP,.bmp)|*.BMP;*.bmp                                    
           |GIF|*.GIF;*.gif
           |TIF|*.tif;*.tiff
           |ICO|*.ico;*.ICO";

If you want to return a format mm/dd/yyyy, then use 101 instead of 103: CONVERT(VARCHAR(10), [MyDate], 101)

A Docker container is running an instance of an image. You can relate an image with a program and a container with a process :)

A good but "heavyweight" solution is to use Twisted - see the bottom.

If you're willing to live with only stdout something along those lines should work:

import subprocess
import sys
popenobj = subprocess.Popen(["ls", "-Rl"], stdout=subprocess.PIPE)
while not popenobj.poll():
   stdoutdata = popenobj.stdout.readline()
   if stdoutdata:
      sys.stdout.write(stdoutdata)
   else:
      break
print "Return code", popenobj.returncode

(If you use read() it tries to read the entire "file" which isn't useful, what we really could use here is something that reads all the data that's in the pipe right now)

One might also try to approach this with threading, e.g.:

import subprocess
import sys
import threading

popenobj = subprocess.Popen("ls", stdout=subprocess.PIPE, shell=True)

def stdoutprocess(o):
   while True:
      stdoutdata = o.stdout.readline()
      if stdoutdata:
         sys.stdout.write(stdoutdata)
      else:
         break

t = threading.Thread(target=stdoutprocess, args=(popenobj,))
t.start()
popenobj.wait()
t.join()
print "Return code", popenobj.returncode

Now we could potentially add stderr as well by having two threads.

Note however the subprocess docs discourage using these files directly and recommends to use communicate() (mostly concerned with deadlocks which I think isn't an issue above) and the solutions are a little klunky so it really seems like the subprocess module isn't quite up to the job (also see: http://www.python.org/dev/peps/pep-3145/ ) and we need to look at something else.

A more involved solution is to use Twisted as shown here: https://twistedmatrix.com/documents/11.1.0/core/howto/process.html

The way you do this with Twisted is to create your process using reactor.spawnprocess() and providing a ProcessProtocol that then processes output asynchronously. The Twisted sample Python code is here: https://twistedmatrix.com/documents/11.1.0/core/howto/listings/process/process.py

The "error_page" parameter makes a redirect, converting the request method to "GET", it is not a custom response page.

The easiest solution is

     server{
         root /var/www/html;
         location ~ \.php {
            if (!-f $document_root/$fastcgi_script_name){
                return 404;
            }
            fastcgi_pass   127.0.0.1:9000;
            include fastcgi_params.default;
            fastcgi_param  SCRIPT_FILENAME  $document_root/$fastcgi_script_name;
        }

By the way, if you want Nginx to process 404 status returned by PHP scripts, you need to add

[fastcgi_intercept_errors][1] on;

E.g.

     location ~ \.php {
            #...
            error_page  404   404.html;
            fastcgi_intercept_errors on;
         }

... right now it happens only to the website I'm testing. I can't post it here because it's confidential.

Then I guess it is one of the sites which is incompatible with TLS1.2. The openssl as used in 12.04 does not use TLS1.2 on the client side while with 14.04 it uses TLS1.2 which might explain the difference. To work around try to explicitly use --secure-protocol=TLSv1. If this does not help check if you can access the site with openssl s_client -connect ... (probably not) and with openssl s_client -tls1 -no_tls1_1, -no_tls1_2 ....

Please note that it might be other causes, but this one is the most probable and without getting access to the site everything is just speculation anyway.

The assumed problem in detail: Usually clients use the most compatible handshake to access a server. This is the SSLv23 handshake which is compatible to older SSL versions but announces the best TLS version the client supports, so that the server can pick the best version. In this case wget would announce TLS1.2. But there are some broken servers which never assumed that one day there would be something like TLS1.2 and which refuse the handshake if the client announces support for this hot new version (from 2008!) instead of just responding with the best version the server supports. To access these broken servers the client has to lie and claim that it only supports TLS1.0 as the best version.

Is Ubuntu 14.04 or wget 1.15 not compatible with TLS 1.0 websites? Do I need to install/download any library/software to enable this connection?

The problem is the server, not the client. Most browsers work around these broken servers by retrying with a lower version. Most other applications fail permanently if the first connection attempt fails, i.e. they don't downgrade by itself and one has to enforce another version by some application specific settings.

I also fixed this issue by running

aspnet_regiis -i

using the visual studio command line tools as an administrator

Expanding on the answers provided here.

You can just do set idx = 1 to set a variable, but that syntax is not recommended because the variable name may clash with a set sub-command. As an example set w=1 would not be valid.

This means that you should prefer the syntax: set variable idx = 1 or set var idx = 1.

Last but not least, you can just use your trusty old print command, since it evaluates an expression. The only difference being that he also prints the result of the expression.

(gdb) p idx = 1
$1 = 1

You can read more about gdb here.

for a lapply-friendly version..

library(data.table)
library(xlsx)

path2txtlist <- your.list.of.txt.files
wb <- createWorkbook()
lapply(seq_along(path2txtlist), function (j) {
sheet <- createSheet(wb, paste("sheetname", j))
addDataFrame(fread(path2txtlist[j]), sheet=sheet, startColumn=1, row.names=FALSE)
})

saveWorkbook(wb, "My_File.xlsx")

It also possible to check tab activity by document.hidden property

Possible solution

document.location = 'app://deep-link';

setInterval( function(){
  if (!document.hidden) {
    document.location = 'https://app.store.link';
  }
}, 1000);

But seems like this not works in Safari

I'd like expand on @JustAGuy's answer. The method I prefer is to use AWS CLI to create a config file. The reason is, with the config file, the CLI or the SDK will automatically look for credentials in the ~/.aws folder. And the good thing is that AWS CLI is written in python.

You can get cli from pypi if you don't have it already. Here are the steps to get cli set up from terminal

$> pip install awscli  #can add user flag 
$> aws configure
AWS Access Key ID [****************ABCD]:[enter your key here]
AWS Secret Access Key [****************xyz]:[enter your secret key here]
Default region name [us-west-2]:[enter your region here]
Default output format [None]:

After this you can access boto and any of the api without having to specify keys (unless you want to use a different credentials).

Here's another answer. It works fast, reliably (see atomicules' answer) and has compact calling code:

' Returns true if item is in the array; false otherwise.
Function IsInArray(ar, item$) As Boolean
    Dim delimiter$, list$

    ' Chr(7) is the ASCII 'Bell' Character.
    ' It was chosen for being unlikely to be found in a normal array.
    delimiter = Chr(7)

    ' Create a list string containing all the items in the array separated by the delimiter.
    list = delimiter & Join(ar, delimiter) & delimiter

    IsInArray = InStr(list, delimiter & item & delimiter) > 0
End Function

Sample usage:

Sub test()
    Debug.Print "Is 'A' in the list?", IsInArray(Split("A,B", ","), "A")
End Sub

If anyone is getting this error after a Phpmyadmin export, using the custom options and adding the "drop tables" statements cleared this right up.

Updated Answer

If you are using the following Windows versions or later: Windows Server 2012, Windows Server 2012 R2, or Windows 8.1 then MakeCert is now deprecated, and Microsoft recommends using the PowerShell Cmdlet New-SelfSignedCertificate.

If you're using an older version such as Windows 7, you'll need to stick with MakeCert or another solution. Some people suggest the Public Key Infrastructure Powershell (PSPKI) Module.

Original Answer

While you can create a self-signed code-signing certificate (SPC - Software Publisher Certificate) in one go, I prefer to do the following:

Creating a self-signed certificate authority (CA)

makecert -r -pe -n "CN=My CA" -ss CA -sr CurrentUser ^
         -a sha256 -cy authority -sky signature -sv MyCA.pvk MyCA.cer

(^ = allow batch command-line to wrap line)

This creates a self-signed (-r) certificate, with an exportable private key (-pe). It's named "My CA", and should be put in the CA store for the current user. We're using the SHA-256 algorithm. The key is meant for signing (-sky).

The private key should be stored in the MyCA.pvk file, and the certificate in the MyCA.cer file.

Importing the CA certificate

Because there's no point in having a CA certificate if you don't trust it, you'll need to import it into the Windows certificate store. You can use the Certificates MMC snapin, but from the command line:

certutil -user -addstore Root MyCA.cer

Creating a code-signing certificate (SPC)

makecert -pe -n "CN=My SPC" -a sha256 -cy end ^
         -sky signature ^
         -ic MyCA.cer -iv MyCA.pvk ^
         -sv MySPC.pvk MySPC.cer

It is pretty much the same as above, but we're providing an issuer key and certificate (the -ic and -iv switches).

We'll also want to convert the certificate and key into a PFX file:

pvk2pfx -pvk MySPC.pvk -spc MySPC.cer -pfx MySPC.pfx

If you want to protect the PFX file, add the -po switch, otherwise PVK2PFX creates a PFX file with no passphrase.

Using the certificate for signing code

signtool sign /v /f MySPC.pfx ^
              /t http://timestamp.url MyExecutable.exe

(See why timestamps may matter)

If you import the PFX file into the certificate store (you can use PVKIMPRT or the MMC snapin), you can sign code as follows:

signtool sign /v /n "Me" /s SPC ^
              /t http://timestamp.url MyExecutable.exe

Some possible timestamp URLs for signtool /t are:

• http://timestamp.verisign.com/scripts/timstamp.dll
• http://timestamp.globalsign.com/scripts/timstamp.dll
• http://timestamp.comodoca.com/authenticode

Full Microsoft documentation

• signtool
• makecert
• pvk2pfx

Downloads

For those who are not .NET developers, you will need a copy of the Windows SDK and .NET framework. A current link is available here: SDK & .NET (which installs makecert in C:\Program Files\Microsoft SDKs\Windows\v7.1). Your mileage may vary.

MakeCert is available from the Visual Studio Command Prompt. Visual Studio 2015 does have it, and it can be launched from the Start Menu in Windows 7 under "Developer Command Prompt for VS 2015" or "VS2015 x64 Native Tools Command Prompt" (probably all of them in the same folder).

For cases of appending to end of existing string:

string = "Sec_"
string += "C_type"
print(string)

results in

Sec_C_type

About prototype bean(s) :

The client code must clean up prototype-scoped objects and release expensive resources that the prototype bean(s) are holding. To get the Spring container to release resources held by prototype-scoped beans, try using a custom bean post-processor, which holds a reference to beans that need to be cleaned up.

ref : https://docs.spring.io/spring/docs/3.0.0.M3/reference/html/ch04s04.html#beans-factory-scopes-prototype

I've discovered that LEFT and RIGHT are not supported functions in Oracle. They are used in SQL Server, MySQL, and some other versions of SQL. In Oracle, you need to use the SUBSTR function. Here are simple examples:

LEFT ('Data', 2) = 'Da'

->   SUBSTR('Data',1,2) = 'Da'

RIGHT ('Data', 2) = 'ta'

->   SUBSTR('Data',-2,2) = 'ta'

Notice that a negative number counts back from the end.

I solved it by open a command prompt as an administrator and point to mysql folder -> bin -> mysql.exe. it works

I wrote a small library expressly for this purpose, available here. The library's chunked function is particularly efficient because it's implemented as a generator, so a substantial amount of memory can be saved in certain situations. It also doesn't rely on the slice notation, so any arbitrary iterator can be used.

import iterlib

print list(iterlib.chunked(xrange(1, 1000), 10))
# prints [(1, 2, 3, 4, 5, 6, 7, 8, 9, 10), (11, 12, 13, 14, 15, 16, 17, 18, 19, 20), ...]

Simply, you can use FormCollection like:

[HttpPost] 
public ActionResult SubmitAction(FormCollection collection)
{
     // Get Post Params Here
 string var1 = collection["var1"];
}

You can also use a class, that is mapped with Form values, and asp.net mvc engine automagically fills it:

//Defined in another file
class MyForm
{
  public string var1 { get; set; }
}

[HttpPost]
public ActionResult SubmitAction(MyForm form)
{      
  string var1 = form1.Var1;
}

Use assign:

assign(paste("orca", i, sep = ""), list_name[[i]])

  var w = 0;var h = 0;

  if(!window.innerWidth){
    if(!(document.documentElement.clientWidth == 0)){

    } else{

    return{x:_x,y:_y};

For Spark 2.1.0, my suggestion would be to use head(n: Int) or take(n: Int) with isEmpty, whichever one has the clearest intent to you.

df.head(1).isEmpty
df.take(1).isEmpty

with Python equivalent:

len(df.head(1)) == 0  # or bool(df.head(1))
len(df.take(1)) == 0  # or bool(df.take(1))

Using df.first() and df.head() will both return the java.util.NoSuchElementException if the DataFrame is empty. first() calls head() directly, which calls head(1).head.

def first(): T = head()
def head(): T = head(1).head

head(1) returns an Array, so taking head on that Array causes the java.util.NoSuchElementException when the DataFrame is empty.

def head(n: Int): Array[T] = withAction("head", limit(n).queryExecution)(collectFromPlan)

So instead of calling head(), use head(1) directly to get the array and then you can use isEmpty.

take(n) is also equivalent to head(n)...

def take(n: Int): Array[T] = head(n)

And limit(1).collect() is equivalent to head(1) (notice limit(n).queryExecution in the head(n: Int) method), so the following are all equivalent, at least from what I can tell, and you won't have to catch a java.util.NoSuchElementException exception when the DataFrame is empty.

df.head(1).isEmpty
df.take(1).isEmpty
df.limit(1).collect().isEmpty

I know this is an older question so hopefully it will help someone using a newer version of Spark.

matrix.size according to the numpy docs returns the Number of elements in the array. Hope that helps.

In my case, the error occurred because I had not initialized the select list in the controller like this:

viewModel.MySelectList = new List<System.Web.Mvc.SelectListItem>();

As none of the existing answers made this clear to me, I post this. Perhaps it helps anybody.

By using ''.join

list1 = ['1', '2', '3']
str1 = ''.join(list1)

Or if the list is of integers, convert the elements before joining them.

list1 = [1, 2, 3]
str1 = ''.join(str(e) for e in list1)

A BigDecimal is an exact way of representing numbers. A Double has a certain precision. Working with doubles of various magnitudes (say d1=1000.0 and d2=0.001) could result in the 0.001 being dropped alltogether when summing as the difference in magnitude is so large. With BigDecimal this would not happen.

The disadvantage of BigDecimal is that it's slower, and it's a bit more difficult to program algorithms that way (due to + - * and / not being overloaded).

If you are dealing with money, or precision is a must, use BigDecimal. Otherwise Doubles tend to be good enough.

I do recommend reading the javadoc of BigDecimal as they do explain things better than I do here :)

The severity level 16 in your example code is typically used for user-defined (user-detected) errors. The SQL Server DBMS itself emits severity levels (and error messages) for problems it detects, both more severe (higher numbers) and less so (lower numbers).

The state should be an integer between 0 and 255 (negative values will give an error), but the choice is basically the programmer's. It is useful to put different state values if the same error message for user-defined error will be raised in different locations, e.g. if the debugging/troubleshooting of problems will be assisted by having an extra indication of where the error occurred.

Reinstall JDK and set system variable JAVA_HOME on your JDK. (e.g. C:\tools\jdk7)
And add JAVA_HOME variable to your PATH system variable

Type in command line

echo %JAVA_HOME%

and

java -version

To verify whether your installation was done successfully.

This problem generally occurs in Windows when your "Java Runtime Environment" registry entry is missing or mismatched with the installed JDK. The mismatch can be due to multiple JDKs.

Steps to resolve:

1. Open the Run window:

   Press windows+R

2. Open registry window:

   Type regedit and enter.

3. Go to: \HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\

4. If Java Runtime Environment is not present inside JavaSoft, then create a new Key and give the name Java Runtime Environment.

5. For Java Runtime Environment create "CurrentVersion" String Key and give appropriate version as value:

6. Create a new subkey of 1.8.

7. For 1.8 create a String Key with name JavaHome with the value of JRE home:

I did something like this myself.

num<0?num*=-1:'';

It checks if the number is negative and if it is, multiply with -1 This does return a value, its up to you if you capture it. In case you want to assign it to something, you should probably do something like:

var out = num<0?num*=-1:num; //I think someone already mentioned this variant.

But it really depends what your goal is. For me it was simple, make it positive if negative, else do nothing. Hence the '' in the code. In this case i used tertiary operator cause I wanted to, it could very well be:

if(num<0)num*=-1;

I saw the bitwise solution here and wanted to comment on that one too.

~--num; //Drawback for this is that num original value will be reduced by 1

This soultion is very fancy in my opinion, we could rewrite it like this:

~(num = num-1);

In simple terms, we take the negative number, take one away from it and then bitwise invert it. If we had bitwise inverted it normally we would get a value 1 too small. You can also do this:

~num+1; //Wont change the actual num value, merely returns the new value

That will do the same but will invert first and then add 1 to the positive number. Although you CANT do this:

~num++; //Wont display the right value.

That will not work cause of precedence, postfix operators such as num++ would be evaluated before ~ and the reason prefix ++num wouldnt work even though it is on the same precedence as bitwise NOT(~), is cause it is evaluated from right to left. I did try to swap them around but it seems that prefix is a little finicky compared to bitwise NOT. The +1 will work because '+' has a higher precedence and will be evaluated later.

I found that solution to be rather fun and decided to expand on it as it was just thrown in there and post people looking at it were probably ignoring it. Although yes, it wont work with floats.

My hopes are that this post hasn't moved away from the original question. :/

C++ programs are translated to assembly programs during the generation of machine code from the source code. It would be virtually wrong to say assembly is slower than C++. Moreover, the binary code generated differs from compiler to compiler. So a smart C++ compiler may produce binary code more optimal and efficient than a dumb assembler's code.

However I believe your profiling methodology has certain flaws. The following are general guidelines for profiling:

1. Make sure your system is in its normal/idle state. Stop all running processes (applications) that you started or that use CPU intensively (or poll over the network).
2. Your datasize must be greater in size.
3. Your test must run for something more than 5-10 seconds.
4. Do not rely on just one sample. Perform your test N times. Collect results and calculate the mean or median of the result.

after you add the user for testing. the user should get an email. open that email by your iOS device, then click "Start testing" it will bring you to testFlight to download the app directly. If you open that email via computer, and then click "Start testing" it will show you another page which have the instruction of how to install the app. and that invitation code is on the last line. those All upper case letters is the code.

Fixed positioning is supposed to define everything in relation to the viewport, so position:fixed is always going to do that. Try using position:relative on the child div instead. (I realize you might need the fixed positioning for other reasons, but if so - you can't really make the width match it's parent with out JS without inherit)

If you are using numpy, printing a single (or multiply) strings to a file can be done with just one line:

numpy.savetxt('Output.txt', ["Purchase Amount: %s" % TotalAmount], fmt='%s')

Google Reflections seems to be much faster than Spring. Found this feature request that adresses this difference: http://www.opensaga.org/jira/browse/OS-738

This is a reason to use Reflections as startup time of my application is really important during development. Reflections seems also to be very easy to use for my use case (find all implementers of an interface).

Aside from @Verhás István answer (which I like), I was expecting a one-liner for the question:

${project.reporting.outputDirectory} resolves to target/site in your project.

When you open Eclipse you should click File ? New ? Dynamic Web Project, and make sure you checked Generate web.xml, as described above.

If you have already created the project, you should go to the WebContent/WEB-INF folder, open web.xml, and put the following lines:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

I had similar problem when importing phone number data from excel to mysql database. So a simple trick without the need to identify the length of the phone number (because the length of the phone numbers varied in my data):

UPDATE table SET phone_num = concat('0', phone_num) 

I just concated 0 in front of the phone_num.

@Html.EditorFor(x => x.ShowComment)


$(function () {
        // set default value to control on document ready instead of 'on'/'off' 
        $("input[type='checkbox'][name='ShowComment']").val(@Model.ShowComment.ToString().ToLower());
    });

    $("#ShowComment").change(function() {
        // this block sets value to checkbox control for "true" / "false"

        var chkVal = $("input[type='checkbox'][name='ShowComment']").val();
        if (chkVal == 'false') $("input[type='checkbox'][name='ShowComment']").val(true);
        else $("input[type='checkbox'][name='ShowComment']").val(false);
