Programs & Examples On #Sshd

Apparently, the SSH server on Raspbian is now disabled by default. If there is no server listening for connections, it will not accept them. You can manually enable the SSH server according to this raspberrypi.org tutorial :

As of the November 2016 release, Raspbian has the SSH server disabled by default.

There are now multiple ways to enable it. Choose one:

From the desktop

1. Launch Raspberry Pi Configuration from the Preferences menu
2. Navigate to the Interfaces tab
3. Select Enabled next to SSH
4. Click OK

From the terminal with raspi-config

1. Enter sudo raspi-config in a terminal window
2. Select Interfacing Options
3. Navigate to and select SSH
4. Choose Yes
5. Select Ok
6. Choose Finish

Start the SSH service with systemctl

sudo systemctl enable ssh
sudo systemctl start ssh

On a headless Raspberry Pi

For headless setup, SSH can be enabled by placing a file named ssh, without any extension, onto the boot partition of the SD card. When the Pi boots, it looks for the ssh file. If it is found, SSH is enabled, and the file is deleted. The content of the file does not matter: it could contain text, or nothing at all.

it works for me. if you want to enable future time for choose, you have to delete maximum date. You need to to do like followings.

 btnDate.setOnClickListener(new View.OnClickListener() {
                       @Override
                       public void onClick(View v) {
                              DialogFragment newFragment = new DatePickerFragment();
                                    newFragment.show(getSupportFragmentManager(), "datePicker");
                            }
                        });

            public static class DatePickerFragment extends DialogFragment
                        implements DatePickerDialog.OnDateSetListener {

                    @Override
                    public Dialog onCreateDialog(Bundle savedInstanceState) {
                        final Calendar c = Calendar.getInstance();
                        int year = c.get(Calendar.YEAR);
                        int month = c.get(Calendar.MONTH);
                        int day = c.get(Calendar.DAY_OF_MONTH);
                        DatePickerDialog dialog = new DatePickerDialog(getActivity(), this, year, month, day);
                        dialog.getDatePicker().setMaxDate(c.getTimeInMillis());
                        return  dialog;
                    }

                    public void onDateSet(DatePicker view, int year, int month, int day) {
                       btnDate.setText(ConverterDate.ConvertDate(year, month + 1, day));
                    }
                }

Try this, working fine -

$array = json_decode(json_encode($array), true);

You should get the array like in $_POST['id']. So you should be able to do this:

foreach ($_POST['id'] as $key => $value) {
    echo $value . "<br />";
}

Input names should be same:

<input name='id[]' type='checkbox' value='1'>
<input name='id[]' type='checkbox' value='2'>
...

First create the dump. Added the --no-create-info --no-create-db flags if table2 already exists:

mysqldump -u user1 -p database1 table1 > dump.sql

Then enter user1 password. Then:

sed -e 's/`table1`/`table2`/' dump.sql

mysql -u user2 -p database2 < dump.sql

Then enter user2 password.

Same as @helmors answer but the approach is more secure as passwords aren't exposed in raw text to the console (reverse-i-search, password sniffers, etc). Other approach is fine if it's executed from a script file with appropriate restrictions placed on it's permissions.

Neither is more correct, so take your pick. The empty return; statement is provided to allow a return in a void function from somewhere other than the end. No other reason I believe.

Update: This solution works and just a call to 'FB.logout()' doesn't work because browser wants a user interaction to actually call this function, so that it knows - it is a user not a script.

<a href="#" onclick="FB.logout();">Logout</a> 

You can easily enable debugging support using an option for the @EnableWebSecurity annotation:

@EnableWebSecurity(debug = true)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
    …
}

If it's for unit tests, another good tool to use is proxyquire. Everytime you proxyquire the module, it will invalidate the module cache and cache a new one. It also allows you to modify the modules required by the file that you are testing.

I used this in my android up and it seems satisfactory although RGB space is not recommended:

    public double colourDistance(int red1,int green1, int blue1, int red2, int green2, int blue2)
{
      double rmean = ( red1 + red2 )/2;
    int r = red1 - red2;
    int g = green1 - green2;
    int b = blue1 - blue2;
    double weightR = 2 + rmean/256;
    double weightG = 4.0;
    double weightB = 2 + (255-rmean)/256;
    return Math.sqrt(weightR*r*r + weightG*g*g + weightB*b*b);
}

Then I used the following to get percent of similarity:

double maxColDist = 764.8339663572415;
double d1 = colourDistance(red1,green1,blue1,red2,green2,blue2);
String s1 = (int) Math.round(((maxColDist-d1)/maxColDist)*100) + "% match";

It works well enough.

Jersey's UriBuilder encodes URI components using application/x-www-form-urlencoded and RFC 3986 as needed. According to the Javadoc

Builder methods perform contextual encoding of characters not permitted in the corresponding URI component following the rules of the application/x-www-form-urlencoded media type for query parameters and RFC 3986 for all other components. Note that only characters not permitted in a particular component are subject to encoding so, e.g., a path supplied to one of the path methods may contain matrix parameters or multiple path segments since the separators are legal characters and will not be encoded. Percent encoded values are also recognized where allowed and will not be double encoded.

Putting the various suggestions together, the cleanest version I was able to come up with (without unreliable grep which triggers parts of words) is:

kill -0 $(pidof mysql) 2> /dev/null || echo "Mysql ain't runnin' message/actions"

kill -0 doesn't kill the process but checks if it exists and then returns true, if you don't have pidof on your system, store the pid when you launch the process:

$ mysql &
$ echo $! > pid_stored

then in the script:

kill -0 $(cat pid_stored) 2> /dev/null || echo "Mysql ain't runnin' message/actions"

Without make validation patterns, You can easily trim begin and end spaces using these modules.Try this.

I found a very simple method that works well:

<input type="text" onclick="this.focus();this.select()">

In ST2 there's a package you can install called Default FileType which does just that.

From what I've found online, this is a bug introduced in JDK 1.7.0_45. I've read it will be fixed in the next release of Java, but it's not out yet. Supposedly, it was fixed in 1.7.0_60b01, but I can't find where to download it and 1.7.0_60b02 re-introduces the bug.

I managed to get around the problem by reverting back to JDK 1.7.0_25. Probably not the solution you wanted, but it's the only way I've been able to get it working. Don't forget add JDK 1.7.0_25 in Eclipse after installing the JDK.

Please DO NOT REPLY directly to this email but go to StackOverflow: Class JavaLaunchHelper is implemented in both. One of the two will be used. Which one is undefined

you could try in this way: get the integer value of the double, subtract this from the original double value, define a rounding range and tests if the absolute number of the new double value(without the integer part) is larger or smaller than your defined range. if it is smaller you can intend it it is an integer value. Example:

public final double testRange = 0.2;

public static boolean doubleIsInteger(double d){
    int i = (int)d;
    double abs = Math.abs(d-i);
    return abs <= testRange;
}

If you assign to d the value 33.15 the method return true. To have better results you can assign lower values to testRange (as 0.0002) at your discretion.

Firstly, as @l33tnerd said, f.close should be outside the for loop.

Secondly, you are only calling readline once, before the loop. That only reads the first line. The trick is that in Python, files act as iterators, so you can iterate over the file without having to call any methods on it, and that will give you one line per iteration:

 if data.find('!masters') != -1:
     f = open('masters.txt')
     for line in f:
           print line,
           sck.send('PRIVMSG ' + chan + " " + line)
     f.close()

Finally, you were referring to the variable lines inside the loop; I assume you meant to refer to line.

Edit: Oh and you need to indent the contents of the if statement.

I would advise, it is slightly better practise to use string model references for ForeignKey relationships if utilising an app based approach to seperation of logical concerns .

So, expanding on Martijn Pieters' answer:

class Person(models.Model):
    name = models.CharField(max_length=50)
    birthday = models.DateField()
    anniversary = models.ForeignKey(
        'app_label.Anniversary', on_delete=models.CASCADE)
    address = models.ForeignKey(
        'app_label.Address', on_delete=models.CASCADE)

class Address(models.Model):
    line1 = models.CharField(max_length=150)
    line2 = models.CharField(max_length=150)
    postalcode = models.CharField(max_length=10)
    city = models.CharField(max_length=150)
    country = models.CharField(max_length=150)

class Anniversary(models.Model):
    date = models.DateField()

TextView textv = (TextView) findViewById(R.id.textview1);
textv.setShadowLayer(1, 0, 0, Color.BLACK);

I believe I have a valid use case for using typeid(), the same way it is valid to use sizeof(). For a template function, I need to special case the code based on the template variable, so that I offer maximum functionality and flexibility.

It is much more compact and maintainable than using polymorphism, to create one instance of the function for each type supported. Even in that case I might use this trick to write the body of the function only once:

Note that because the code uses templates, the switch statement below should resolve statically into only one code block, optimizing away all the false cases, AFAIK.

Consider this example, where we may need to handle a conversion if T is one type vs another. I use it for class specialization to access hardware where the hardware will use either myClassA or myClassB type. On a mismatch, I need to spend time converting the data.

switch ((typeid(T)) {
  case typeid(myClassA):
    // handle that case
    break;
  case typeid(myClassB):
    // handle that case
    break;
  case typeid(uint32_t):
    // handle that case
    break;
  default:
    // handle that case
}

You can use python code directly in batch file, https://gist.github.com/jadient/9849314.

@echo off & python -x "%~f0" %* & goto :eof
import sys
print("Hello World!")

See explanation, Python command line -x option.

Looking at your classpath you exclude src/main/resources and src/test/resources:

    <classpathentry excluding="**" kind="src" output="target/classes" path="src/main/resources"/>
    <classpathentry excluding="**" kind="src" output="target/test-classes" path="src/test/resources"/>

Is there a reason for it? Try not to exclude a classpath to spring-config.xml :)

It is a general vision. Details are depended on real language realisation

lock - thread synchronization tool. When thread get a lock it becomes a single thread which is able to execute a block of code. All others thread are blocked. Only thread which owns by lock can unlock it

mutex - mutual exclusion lock. It is a kind of lock. On some languages it is inter-process mechanism, on some languages it is a synonym of lock. For example Java uses lock in synchronised and java.util.concurrent.locks.Lock

semaphore - allows a number of threads to access a shared resource. You can find that mutex also can be implemented by semaphore. It is a standalone object which manage an access to shared resource. You can find that any thread can signal and unblock. Also it is used for signalling

[iOS lock, mutex, semaphore]

I suspect you may want yo hear something else, but this is what you asked for.

It means "not equal to" (as in, the values in cells E37-N37 are not equal to "", or in other words, they are not empty.)

function addAttr(scope, el, attrName, attrValue) {
  el.replaceWith($compile(el.clone().attr(attrName, attrValue))(scope));
}

constexpr indicates a value that's constant and known during compilation.
const indicates a value that's only constant; it's not compulsory to know during compilation.

int sz;
constexpr auto arraySize1 = sz;    // error! sz's value unknown at compilation
std::array<int, sz> data1;         // error! same problem

constexpr auto arraySize2 = 10;    // fine, 10 is a compile-time constant
std::array<int, arraySize2> data2; // fine, arraySize2 is constexpr

Note that const doesn’t offer the same guarantee as constexpr, because const objects need not be initialized with values known during compilation.

int sz;
const auto arraySize = sz;       // fine, arraySize is const copy of sz
std::array<int, arraySize> data; // error! arraySize's value unknown at compilation

All constexpr objects are const, but not all const objects are constexpr.

If you want compilers to guarantee that a variable has a value that can be used in contexts requiring compile-time constants, the tool to reach for is constexpr, not const.

C:\inetpub\wwwroot\ember-roomviewer>git branch -d guided-furniture
warning: not deleting branch 'guided-furniture' that is not yet merged to
         'refs/remotes/origin/guided-furniture', even though it is merged to HEAD.
error: The branch 'guided-furniture' is not fully merged.
If you are sure you want to delete it, run 'git branch -D guided-furniture'.

The solution for me was simply that the feature branch needed to be pushed up to the remote. Then when I ran:

git push origin guided-furniture
/* You might need to fetch here */
git branch -d guided-furniture

Deleted branch guided-furniture (was 1813496).

You are looking for -H option in gnu grep.

To solve the “Keyset does not exist” when browsing from IIS: It may be for the private permission

To view and give the permission:

1. Run>mmc>yes
2. click on file
3. Click on Add/remove snap-in…
4. Double click on certificate
5. Computer Account
6. Next
7. Finish
8. Ok
9. Click on Certificates(Local Computer)
10. Click on Personal
11. Click Certificates

To give the permission:

1. Right Click on the name of certificate
2. All Tasks>Manage Private Keys…
3. Add and give the privilege( adding IIS_IUSRS and giving it the privilege works for me )

if ($select.find('option[value=' + val + ']').length) {...}

Here a different approach to get meta data. This very helpful SQL command returns you the table / view definition as text:

Check whether you have put name="your_radio" where you have inserted radio tag

if you have done this then check your php code. Use isset()

e.g.

   if(isset($_POST['submit']))
   {
    /*other variables*/
    $radio_value = $_POST["your_radio"];
   }

If you have done this as well then we need to look through your codes

You just need to wrap object in ()

var arr = [{_x000D_
  id: 1,_x000D_
  name: 'bill'_x000D_
}, {_x000D_
  id: 2,_x000D_
  name: 'ted'_x000D_
}]_x000D_
_x000D_
var result = arr.map(person => ({ value: person.id, text: person.name }));_x000D_
console.log(result)

Almost the same as in your previous question:

$iterator = new RecursiveIteratorIterator(
                new RecursiveDirectoryIterator($yourStartingPath), 
            RecursiveIteratorIterator::SELF_FIRST);

foreach($iterator as $file) {
    if($file->isDir()) {
        echo strtoupper($file->getRealpath()), PHP_EOL;
    }
}

Replace strtoupper with your desired function.

If one is on a Linux distro (e.g. CentOS, Debian) then perhaps the most accessible way to find out about core files and related conditions is in the man page. Just run the following command from a terminal:

man 5 core

Right now (as of 2008), all the SOAP libraries available for Python suck. I recommend avoiding SOAP if possible. The last time we where forced to use a SOAP web service from Python, we wrote a wrapper in C# that handled the SOAP on one side and spoke COM out the other.

You can try:

body{ margin:0 auto; }

If this happens to you with an OpenJDK install on Mac OS X (as opposed to Linux), and you do have the official Mac OS X Java (i.e. latest Java 6) installed through Software Update, you can just do this:

cd $OPENJDK_HOME/Contents/Home/jre/lib/security
ln -s /System/Library/Java/Support/CoreDeploy.bundle/Contents/Home/lib/security/cacerts
ln -s /System/Library/Java/Support/Deploy.bundle/Contents/Home/lib/security/blacklist 
ln -s /System/Library/Java/Support/Deploy.bundle/Contents/Home/lib/security/trusted.libraries 

where $OPENJDK_HOME is the root directory of your OpenJDK install, typically OPENJDK_HOME=/Library/Java/JavaVirtualMachines/1.7.0u.jdk. This is identical to how official Java installs on Mac OS X acquire these files - they also just symlink them from those system bundles. Works for Lion, not sure for earlier versions of the OS.

According to the api docs, doing:

dataFrame1.except(dataFrame2)

will return a new DataFrame containing rows in dataFrame1 but not in dataframe2.

In addition to Marty's excellent Answer, the SystemVerilog specification offers the byte data type. The following declares a 4x8-bit variable (4 bytes), assigns each byte a value, then displays all values:

module tb;

byte b [4];

initial begin
    foreach (b[i]) b[i] = 1 << i;
    foreach (b[i]) $display("Address = %0d, Data = %b", i, b[i]);
    $finish;
end

endmodule

This prints out:

Address = 0, Data = 00000001
Address = 1, Data = 00000010
Address = 2, Data = 00000100
Address = 3, Data = 00001000

This is similar in concept to Marty's reg [7:0] a [0:3];. However, byte is a 2-state data type (0 and 1), but reg is 4-state (01xz). Using byte also requires your tool chain (simulator, synthesizer, etc.) to support this SystemVerilog syntax. Note also the more compact foreach (b[i]) loop syntax.

The SystemVerilog specification supports a wide variety of multi-dimensional array types. The LRM can explain them better than I can; refer to IEEE Std 1800-2005, chapter 5.

Just to add to the existing great answers here - building on the code in the accepted one, which uses a delegate void MyEventHandler(string foo)...

Because the compiler knows the delegate type of the SomethingHappened event, this:

myObj.SomethingHappened += HandleSomethingHappened;

Is totally equivalent to:

myObj.SomethingHappened += new MyEventHandler(HandleSomethingHappened);

And handlers can also be unregistered with -= like this:

// -= removes the handler from the event's list of "listeners":
myObj.SomethingHappened -= HandleSomethingHappened;

For completeness' sake, raising the event can be done like this, only in the class that owns the event:

//Firing the event is done by simply providing the arguments to the event:
var handler = SomethingHappened; // thread-local copy of the event
if (handler != null) // the event is null if there are no listeners!
{
    handler("Hi there!");
}

The thread-local copy of the handler is needed to make sure the invocation is thread-safe - otherwise a thread could go and unregister the last handler for the event immediately after we checked if it was null, and we would have a "fun" NullReferenceException there.

C# 6 introduced a nice short hand for this pattern. It uses the null propagation operator.

SomethingHappened?.Invoke("Hi there!");

I had the same problem. I changed the localhost parameter in the mysqli object to '127.0.0.1' instead of writing 'localhost'. It worked; I’m not sure how or why.

$db_connection = new mysqli("127.0.0.1","root","","db_name");

Hope it helps.

Just add @Transactional annotation on top of your test:

@RunWith(SpringJUnit4ClassRunner.class)  
@ContextConfiguration(locations = {"testContext.xml"})
@Transactional
public class StudentSystemTest {

By default Spring will start a new transaction surrounding your test method and @Before/@After callbacks, rolling back at the end. It works by default, it's enough to have some transaction manager in the context.

From: 10.3.5.4 Transaction management (bold mine):

In the TestContext framework, transactions are managed by the TransactionalTestExecutionListener. Note that TransactionalTestExecutionListener is configured by default, even if you do not explicitly declare @TestExecutionListeners on your test class. To enable support for transactions, however, you must provide a PlatformTransactionManager bean in the application context loaded by @ContextConfiguration semantics. In addition, you must declare @Transactional either at the class or method level for your tests.

Solved this by adding following

RewriteCond %{ENV:REDIRECT_STATUS} 200 [OR]
 RewriteCond %{REQUEST_FILENAME} -f [OR]
 RewriteCond %{REQUEST_FILENAME} -d
 RewriteRule ^ - [L]

If I'm not mistaken, this should match any valid JavaScript number value, excluding constants (Infinity, NaN) and the sign operators +/- (because they are not actually part of the number as far as I concerned, they are separate operators):

I needed this for a tokenizer, where sending the number to JavaScript for evaluation wasn't an option... It's definitely not the shortest possible regular expression, but I believe it catches all the finer subtleties of JavaScript's number syntax.

/^(?:(?:(?:[1-9]\d*|\d)\.\d*|(?:[1-9]\d*|\d)?\.\d+|(?:[1-9]\d*|\d)) 
(?:[e]\d+)?|0[0-7]+|0x[0-9a-f]+)$/i

Valid numbers would include:

 - 0
 - 00
 - 01
 - 10
 - 0e1
 - 0e01
 - .0
 - 0.
 - .0e1
 - 0.e1
 - 0.e00
 - 0xf
 - 0Xf

Invalid numbers would be

 - 00e1
 - 01e1
 - 00.0
 - 00x0
 - .
 - .e0

I suggest merging develop and master with that command

git checkout master

git merge --commit --no-ff --no-edit develop

Use sessions

On your search.jsp

Put your scard in sessions using session.setAttribute("scard","scard")

//the 1st variable is the string name that you will retrieve in ur next page,and the 2nd variable is the its value,i.e the scard value.

And in your next page you retrieve it using session.getAttribute("scard")

UPDATE

<input type="text" value="<%=session.getAttribute("scard")%>"/>

I have created a small utility function, this works well for me

def display_text_max_col_width(df, width):
    with pd.option_context('display.max_colwidth', width):
        print(df)

display_text_max_col_width(train_df["Description"], 800)

I can change length of the width as per my requirement, without setting any option permanently.

# First use prune --dry-run to filter+delete the local branches
git remote prune origin --dry-run \

Do you have to use DataTable.Select()? I prefer to write a linq query for this kind of thing.

var dValue=  from row in myDataTable.AsEnumerable()
             where row.Field<int>("A") == 1 
                   && row.Field<int>("B") == 2 
                   && row.Field<int>("C") == 3

C:\Program Files\Java\jdk1.8.0_65\bin

The JDK path might change when you update JAVA. For Mac you should go to the following path to check the JAVA version installed.

/Library/Java/JavaVirtualMachines/

Next, say JDK version that you find is jdk1.8.0_151.jdk, the path to home directory within it is the JDK home path.

In my case it was :

/Library/Java/JavaVirtualMachines/jdk1.8.0_151.jdk/Contents/Home

You can configure it by going to File -> Project Structure -> SDKs.

Use the fully classified name of database file

Use- /home/ankit/Desktop/DS/Week-7-MachineLearning/Week-7-MachineLearning/soccer/database.sqlite

To me it is about 2 different meanings of symbol =:

1. In math x = sin(t) means, that x is different name for sin(t). So writing x + y is the same thing as sin(t) + y. Functional reactive programming is like math in this respect: if you write x + y, it is computed with whatever the value of t is at the time it's used.
2. In C-like programming languages (imperative languages), x = sin(t) is an assignment: it means that x stores the value of sin(t) taken at the time of the assignment.

the one liner for python3 is :

def bytes_xor(a, b) :
    return bytes(x ^ y for x, y in zip(a, b))

where a, b and the returned value are bytes() instead of str() of course

can't be easier, I love python3 :)

The problem you have found is that view is different from your UIView. 'view' refers to the entire view. For example your home screen is a view.

You need to clearly separate the entire 'view' your 'UIView' and your 'UILabel'

You can accomplish this by going to your storyboard, clicking on the item, Identity Inspector, and changing the Restoration ID.

Now to access each item in your code using the restoration ID

desc keyspaces will do it for you.

Short answer:

git log --full-history -- your_file

will show you all commits in your repo's history, including merge commits, that touched your_file. The last (top) one is the one that deleted the file.

Some explanation:

The --full-history flag here is important. Without it, Git performs "history simplification" when you ask it for the log of a file. The docs are light on details about exactly how this works and I lack the grit and courage required to try to figure it out from the source code, but the git-log docs have this much to say:

Default mode

Simplifies the history to the simplest history explaining the final state of the tree. Simplest because it prunes some side branches if the end result is the same (i.e. merging branches with the same content)

This is obviously concerning when the file whose history we want is deleted, since the simplest history explaining the final state of a deleted file is no history. Is there a risk that git log without --full-history will simply claim that the file was never created? Unfortunately, yes. Here's a demonstration:

    Added bar

Notice how git log -- bar in the terminal dump above resulted in literally no output; Git is "simplifying" history down into a fiction where bar never existed. git log --full-history -- bar, on the other hand, gives us the commit that created bar and the commit that deleted it.

To be clear: this issue isn't merely theoretical. I only looked into the docs and discovered the --full-history flag because git log -- some_file was failing for me in a real repository where I was trying to track a deleted file down. History simplification might sometimes be helpful when you're trying to understand how a currently-existing file came to be in its current state, but when trying to track down a file deletion it's more likely to screw you over by hiding the commit you care about. Always use the --full-history flag for this use case.

You can initialize after filling the array or you can write:

 small =~ unsigned(0)/2; // Using the bit-wise complement to flip 0's bits and dividing by 2 because unsigned can hold twice the +ve value an

integer can hold.

 big =- 1*(small) - 1;

instead of:

big = small = values[0]

because when you write this line before filling the array, big and small values will equal to a random leftover value (as integer is a POD) from the memory and if those numbers are either bigger or smaller than any other value in you array, you will get them as an output.

Maybe you should try removing "new" keyword and see if works. Because last time I got this error when I tried creating Typeface something like this:

Typeface typeface = new Typeface().create("Arial",Typeface.BOLD);

You might want to look into a Python package manager like pip. If you don't want to use a Python package manager, you should be able to download M2Crypto and build/compile/install over the old installation.

It is always painful for developers to with ng-options. For example: Getting an empty/blank selected value in the select tag. Especially when dealing with JSON objects in ng-options, it becomes more tedious. Here I have done some exercises on that.

Objective: Iterate array of JSON objects through ng-option and set selected first element.

Data:

someNames = [{"id":"1", "someName":"xyz"}, {"id":"2", "someName":"abc"}]

In the select tag I had to show xyz and abc, where xyz must be selected without much effort.

HTML:

<pre class="default prettyprint prettyprinted" style=""><code>
    &lt;select class="form-control" name="test" style="width:160px"    ng-options="name.someName for name in someNames" ng-model="testModel.test" ng-selected = "testModel.test = testModel.test || someNames[0]"&gt;
&lt;/select&gt;
</code></pre>

By above code sample, you might get out of this exaggeration.

Another reference:

if you already know your folder is: E:\ftproot\sales then you do not need to use Server.MapPath, this last one is needed if you only have a relative virtual path like ~/folder/folder1 and you want to know the real path in the disk...

$(document).on('change', '.custom-file-input', function (event) {
    $(this).next('.custom-file-label').html(event.target.files[0].name);
})

Best of all worlds. Works on dynamically created inputs, and uses actual file name.

Use titleLabel instead. The font property is deprecated in iOS 3.0. It also does not work in Objective-C. titleLabel is label used for showing title on UIButton.

myButton.titleLabel?.font =  UIFont(name: YourfontName, size: 20)

However, while setting title text you should only use setTitle:forControlState:. Do not use titleLabel to set any text for title directly.

extern "C" is a linkage specification which is used to call C functions in the Cpp source files. We can call C functions, write Variables, & include headers. Function is declared in extern entity & it is defined outside. Syntax is

Type 1:

extern "language" function-prototype

Type 2:

extern "language"
{
     function-prototype
};

eg:

#include<iostream>
using namespace std;

extern "C"
{
     #include<stdio.h>    // Include C Header
     int n;               // Declare a Variable
     void func(int,int);  // Declare a function (function prototype)
}

int main()
{
    func(int a, int b);   // Calling function . . .
    return 0;
}

// Function definition . . .
void func(int m, int n)
{
    //
    //
}

Visual Studio 2017

1. Open Visual Studio
2. In Tools -> Extensions and Updates -> Online
3. Search for 'rdlc'
4. Install Microsoft Rdlc Report Designer (23.3 MB)
5. Close Visual Studio, let the installer run and open Visual Studio to see the rdlc in the designer.

A little late to the party, but this is how I did it for an insert:

DECLARE @ManagerID AS Varchar (25) = 'NA'
DECLARE @ManagerEmail AS Varchar (50) = 'NA'
Declare @RecordCount AS int = 0

SET @ManagerID = ?
SET @ManagerEmail = ?
SET @RecordCount = ?

Just put DROP TABLE IF EXISTS `tablename`; before your CREATE TABLE statement.

That statement drops the table if it exists but will not throw an error if it does not.

in addition to what Kirk said I want to tell you that just "playing around" won't help you to learn asp.net, and there is a lot of free and very good tutorials .
take a look on the asp.net official site tutorials and on 4GuysFromRolla site

Consider using a dictionary:

myDict = {}

for i in range(20):
    myDict[i] = i * i

print(5 in myDict)

Use atoi() from <stdlib.h>

http://linux.die.net/man/3/atoi

Or, write your own atoi() function which will convert char* to int

int a2i(const char *s)
{
  int sign=1;
  if(*s == '-'){
    sign = -1;
    s++;
  }
  int num=0;
  while(*s){
    num=((*s)-'0')+num*10;
    s++;   
  }
  return num*sign;
}

Ok so this one works. Just in case anybody wants it, here's the version that works for me :)

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.Base64;


public class HttpBasicAuth {

    public static void main(String[] args) {

        try {
            URL url = new URL ("http://ip:port/login");
            String encoding = Base64.getEncoder().encodeToString(("test1:test1").getBytes(?"UTF??-8"?));

            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("POST");
            connection.setDoOutput(true);
            connection.setRequestProperty  ("Authorization", "Basic " + encoding);
            InputStream content = (InputStream)connection.getInputStream();
            BufferedReader in   = 
                new BufferedReader (new InputStreamReader (content));
            String line;
            while ((line = in.readLine()) != null) {
                System.out.println(line);
            }
        } catch(Exception e) {
            e.printStackTrace();
        }

    }

}

Just use the *args parameter, which allows you to pass as many arguments as you want after your a,b,c. You would have to add some logic to map args->c,d,e,f but its a "way" of overloading.

def myfunc(a,b, *args, **kwargs):
   for ar in args:
      print ar
myfunc(a,b,c,d,e,f)

And it will print values of c,d,e,f

Similarly you could use the kwargs argument and then you could name your parameters.

def myfunc(a,b, *args, **kwargs):
      c = kwargs.get('c', None)
      d = kwargs.get('d', None)
      #etc
myfunc(a,b, c='nick', d='dog', ...)

And then kwargs would have a dictionary of all the parameters that are key valued after a,b

Building upon busylee's answer, this is how you can make a drawable that only has one unrounded corner (top-left, in this example):

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle">
            <solid android:color="@color/white" />
            <!-- A numeric value is specified in "radius" for demonstrative purposes only,
                  it should be @dimen/val_name -->
            <corners android:radius="10dp" />
        </shape>
    </item>
    <!-- To keep the TOP-LEFT corner UNROUNDED set both OPPOSITE offsets (bottom+right): -->
    <item
        android:bottom="10dp"
        android:right="10dp">
        <shape android:shape="rectangle">
            <solid android:color="@color/white" />
        </shape>
    </item>
</layer-list>

Please note that the above drawable is not shown correctly in the Android Studio preview (2.0.0p7). To preview it anyway, create another view and use this as android:background="@drawable/...".

Easiest solution:

Esc, Ctrl-A, Shift-Enter.

I had a similar problem, what solved it was html_entity_decode.

My code is:

$content = file_get_contents("http://example.com/fr");
$x = new SimpleXMLElement($content);
foreach($x->channel->item as $entry) {
    $subEntry = html_entity_decode($entry->description);
}

In here I am retrieving an xml file (in French), that's why I'm using this $x object variable. And only then I decode it into this variable $subEntry.

I tried mb_convert_encoding but this didn't work for me.

Copy/Paste what is below into your code:

SqlConnection cnTrupp = new SqlConnection("Initial Catalog = Database;Data Source = localhost;Persist Security Info=True;Integrated Security = True;");

Keep in mind that this solution uses your windows account to log in.

As John and Adam have said, this has to do with how you are logging in (or not logging in). Look at the link John provided to get a better explanation.

I was facing this issue and fixed by putting a check in form attribute. This issue can happen when the FormGroup is not initialized.

<form [formGroup]="loginForm" *ngIf="loginForm">
OR
<form [formGroup]="loginForm" *ngIf="this.loginForm">

This will not render the form until it is initialized.

If you face an issue of CORS, you can use https://api.ipify.org/.

function httpGet(theUrl)
{
    var xmlHttp = new XMLHttpRequest();
    xmlHttp.open( "GET", theUrl, false );
    xmlHttp.send( null );
    return xmlHttp.responseText;
}


publicIp = httpGet("https://api.ipify.org/");
alert("Public IP: " + publicIp);

I agree that using synchronous HTTP call is not good idea. You can use async ajax call then.

You can add colon before attribute (also can use conditions) like

<div :class="current? 'active': '' " > 
<button :disabled="InvalidForm? true : false " >

If you want to set a dynamic value like props then you also can use colon before attribute name like :

<Child :data="userList" />

The option -C works; just for clarification I'll post 2 examples:

1. creation of a tarball without the full path: full path /home/testuser/workspace/project/application.war and what we want is just project/application.war so:

   tar -cvf output_filename.tar  -C /home/testuser/workspace project
   

   Note: there is a space between workspace and project; tar will replace full path with just project .

2. extraction of tarball with changing the target path (default to ., i.e current directory)

   tar -xvf output_filename.tar -C /home/deploy/
   

   tar will extract tarball based on given path and preserving the creation path; in our example the file application.war will be extracted to /home/deploy/project/application.war.

   /home/deploy: given on extract
   project: given on creation of tarball

Note : if you want to place the created tarball in a target directory, you just add the target path before tarball name. e.g.:

tar -cvf /path/to/place/output_filename.tar  -C /home/testuser/workspace project

in angular4 foreach like that. try this.

 selectChildren(data, $event) {
      let parentChecked = data.checked;
       this.hierarchicalData.forEach(obj => {
          obj.forEach(childObj=> {
            value.checked = parentChecked;
         });
      });
    }

Same error can raise by mixing: tabs + spaces.

with open('/foo', 'w') as f:
 (spaces OR  tab) print f       <-- success
 (spaces AND tab) print f       <-- fail

Let's try this

select convert(varchar, getdate(), 108) 

Just try a few moment ago

You can use Series.isin:

df = df[~df.datecolumn.isin(a)]

While the error message suggests that all() or any() can be used, they are useful only when you want to reduce the result into a single Boolean value. That is however not what you are trying to do now, which is to test the membership of every values in the Series against the external list, and keep the results intact (i.e., a Boolean Series which will then be used to slice the original DataFrame).

You can read more about this in the Gotchas.

GitHub has a new option relative to the preceding answers, just copy/paste the command lines from the PR:

1. Scroll to the bottom of the PR to see the Merge or Squash and merge button
2. Click the link on the right: view command line instructions
3. Press the Copy icon to the right of Step 1
4. Paste the commands in your terminal

Could there be contention for the assembly? Check to see whether there's another application with a file lock on the DLL.

If this is the reason, it should be easy to use a tool like Sysinternal's Process Explorer to discover the offending program.

HTH, Clay

Just remove "build" folder in youy project directory and compile again, i hope it works for you too

Try this:

return preg_replace("/[^0-9]/", "",$c);

Check out Reuxables although it comes at a cost.

So far the answers seem to rely on code being run instantly. If you set a timer for 1000ms, it will actually be around 1008 instead.

Here is how you should do it:

function timer(time,update,complete) {
    var start = new Date().getTime();
    var interval = setInterval(function() {
        var now = time-(new Date().getTime()-start);
        if( now <= 0) {
            clearInterval(interval);
            complete();
        }
        else update(Math.floor(now/1000));
    },100); // the smaller this number, the more accurate the timer will be
}

To use, call:

timer(
    5000, // milliseconds
    function(timeleft) { // called every step to update the visible countdown
        document.getElementById('timer').innerHTML = timeleft+" second(s)";
    },
    function() { // what to do after
        alert("Timer complete!");
    }
);

You can also use the "-u" option to specify the path. I find this helpful on machines where my .bashrc doesn't get sourced in non-interactive sessions. For example,

git clone -u /home/you/bin/git-upload-pack you@machine:code

The copy command is a SQL*Plus command (not a SQL Developer command). If you have your tnsname entries setup for SID1 and SID2 (e.g. try a tnsping), you should be able to execute your command.

Another assumption is that table1 has the same columns as the message_table (and the columns have only the following data types: CHAR, DATE, LONG, NUMBER or VARCHAR2). Also, with an insert command, you would need to be concerned about primary keys (e.g. that you are not inserting duplicate records).

I tried a variation of your command as follows in SQL*Plus (with no errors):

copy from scott/tiger@db1 to scott/tiger@db2 create new_emp using select * from emp;

After I executed the above statement, I also truncate the new_emp table and executed this command:

copy from scott/tiger@db1 to scott/tiger@db2 insert new_emp using select * from emp;

With SQL Developer, you could do the following to perform a similar approach to copying objects:

1. On the tool bar, select Tools>Database copy.

2. Identify source and destination connections with the copy options you would like.

3. For object type, select table(s).

4. Specify the specific table(s) (e.g. table1).

The copy command approach is old and its features are not being updated with the release of new data types. There are a number of more current approaches to this like Oracle's data pump (even for tables).

Hello please note like real work.

Children can not have two mother

So in java, subclass can not have two parent class.

No mention of the converters kwarg for ConfigParser() in any of these answers was rather disappointing.

According to the documentation you can pass a dictionary to ConfigParser that will add a get method for both the parser and section proxies. So for a list:

example.ini

[Germ]
germs: a,list,of,names, and,1,2, 3,numbers

Parser example:

cp = ConfigParser(converters={'list': lambda x: [i.strip() for i in x.split(',')]})
cp.read('example.ini')
cp.getlist('Germ', 'germs')
['a', 'list', 'of', 'names', 'and', '1', '2', '3', 'numbers']
cp['Germ'].getlist('germs')
['a', 'list', 'of', 'names', 'and', '1', '2', '3', 'numbers']

This is my personal favorite as no subclassing is necessary and I don't have to rely on an end user to perfectly write JSON or a list that can be interpreted by ast.literal_eval.

You could do:

class myClass : ICloneable
{
    public String test;
    public object Clone()
    {
        return this.MemberwiseClone();
    }
}

then you can do

myClass a = new myClass();
myClass b = (myClass)a.Clone();

N.B. MemberwiseClone() Creates a shallow copy of the current System.Object.

A very useful solution here for SQLite3. Because the OP does not indicate MySQL specifically and there was a failed attempt to use some solutions on SQLite.

    $table_name = 'content_containers';
    $container_result = $connect->query("PRAGMA table_info(" . $table_name . ")");
    $container_result->setFetchMode(PDO::FETCH_ASSOC);


    foreach ($container_result as $conkey => $convalue)
    {

        $elements[$convalue['name']] = $convalue['name'];

    }

This returns an array. Since this is a direct information dump you'll need to iterate over and filter the results to get something like this:

Array
(
    [ccid] => ccid
    [administration_title] => administration_title
    [content_type_id] => content_type_id
    [author_id] => author_id
    [date_created] => date_created
    [language_id] => language_id
    [publish_date] => publish_date
    [status] => status
    [relationship_ccid] => relationship_ccid
    [url_alias] => url_alias
)

This is particularly nice to have when the table is empty.

$resource was meant to retrieve data from an endpoint, manipulate it and send it back. You've got some of that in there, but you're not really leveraging it for what it was made to do.

It's fine to have custom methods on your resource, but you don't want to miss out on the cool features it comes with OOTB.

EDIT: I don't think I explained this well enough originally, but $resource does some funky stuff with returns. Todo.get() and Todo.query() both return the resource object, and pass it into the callback for when the get completes. It does some fancy stuff with promises behind the scenes that mean you can call $save() before the get() callback actually fires, and it will wait. It's probably best just to deal with your resource inside of a promise then() or the callback method.

Standard use

var Todo = $resource('/api/1/todo/:id');

//create a todo
var todo1 = new Todo();
todo1.foo = 'bar';
todo1.something = 123;
todo1.$save();

//get and update a todo
var todo2 = Todo.get({id: 123});
todo2.foo += '!';
todo2.$save();

//which is basically the same as...
Todo.get({id: 123}, function(todo) {
   todo.foo += '!';
   todo.$save();
});

//get a list of todos
Todo.query(function(todos) {
  //do something with todos
  angular.forEach(todos, function(todo) {
     todo.foo += ' something';
     todo.$save();
  });
});

//delete a todo
Todo.$delete({id: 123});

Likewise, in the case of what you posted in the OP, you could get a resource object and then call any of your custom functions on it (theoretically):

var something = src.GetTodo({id: 123});
something.foo = 'hi there';
something.UpdateTodo();

I'd experiment with the OOTB implementation before I went and invented my own however. And if you find you're not using any of the default features of $resource, you should probably just be using $http on it's own.

Update: Angular 1.2 and Promises

As of Angular 1.2, resources support promises. But they didn't change the rest of the behavior.

To leverage promises with $resource, you need to use the $promise property on the returned value.

Example using promises

var Todo = $resource('/api/1/todo/:id');

Todo.get({id: 123}).$promise.then(function(todo) {
   // success
   $scope.todos = todos;
}, function(errResponse) {
   // fail
});

Todo.query().$promise.then(function(todos) {
   // success
   $scope.todos = todos;
}, function(errResponse) {
   // fail
});

Just keep in mind that the $promise property is a property on the same values it was returning above. So you can get weird:

These are equivalent

var todo = Todo.get({id: 123}, function() {
   $scope.todo = todo;
});

Todo.get({id: 123}, function(todo) {
   $scope.todo = todo;
});

Todo.get({id: 123}).$promise.then(function(todo) {
   $scope.todo = todo;
});

var todo = Todo.get({id: 123});
todo.$promise.then(function() {
   $scope.todo = todo;
});

install JDK it will work ,

here is the jdk link to download .

Use this cmd to display the packages in your device (for windows users)

adb shell pm list packages

then you can delete completely the package with the following cmd

adb uninstall com.example.myapp

Well the solution with NetHttp has a drawback that is when posting big files it loads the whole file into memory first.

After playing a bit with it I came up with the following solution:

class Multipart

  def initialize( file_names )
    @file_names = file_names
  end

  def post( to_url )
    boundary = '----RubyMultipartClient' + rand(1000000).to_s + 'ZZZZZ'

    parts = []
    streams = []
    @file_names.each do |param_name, filepath|
      pos = filepath.rindex('/')
      filename = filepath[pos + 1, filepath.length - pos]
      parts << StringPart.new ( "--" + boundary + "\r\n" +
      "Content-Disposition: form-data; name=\"" + param_name.to_s + "\"; filename=\"" + filename + "\"\r\n" +
      "Content-Type: video/x-msvideo\r\n\r\n")
      stream = File.open(filepath, "rb")
      streams << stream
      parts << StreamPart.new (stream, File.size(filepath))
    end
    parts << StringPart.new ( "\r\n--" + boundary + "--\r\n" )

    post_stream = MultipartStream.new( parts )

    url = URI.parse( to_url )
    req = Net::HTTP::Post.new(url.path)
    req.content_length = post_stream.size
    req.content_type = 'multipart/form-data; boundary=' + boundary
    req.body_stream = post_stream
    res = Net::HTTP.new(url.host, url.port).start {|http| http.request(req) }

    streams.each do |stream|
      stream.close();
    end

    res
  end

end

class StreamPart
  def initialize( stream, size )
    @stream, @size = stream, size
  end

  def size
    @size
  end

  def read ( offset, how_much )
    @stream.read ( how_much )
  end
end

class StringPart
  def initialize ( str )
    @str = str
  end

  def size
    @str.length
  end

  def read ( offset, how_much )
    @str[offset, how_much]
  end
end

class MultipartStream
  def initialize( parts )
    @parts = parts
    @part_no = 0;
    @part_offset = 0;
  end

  def size
    total = 0
    @parts.each do |part|
      total += part.size
    end
    total
  end

  def read ( how_much )

    if @part_no >= @parts.size
      return nil;
    end

    how_much_current_part = @parts[@part_no].size - @part_offset

    how_much_current_part = if how_much_current_part > how_much
      how_much
    else
      how_much_current_part
    end

    how_much_next_part = how_much - how_much_current_part

    current_part = @parts[@part_no].read(@part_offset, how_much_current_part )

    if how_much_next_part > 0
      @part_no += 1
      @part_offset = 0
      next_part = read ( how_much_next_part  )
      current_part + if next_part
        next_part
      else
        ''
      end
    else
      @part_offset += how_much_current_part
      current_part
    end
  end
end

Try this:

$("#upload_link,#upload_link2,#upload_link3").each(function(){
    $(this).upload({
        //whateveryouwant
    });
});

For Python 3xx:

import time
for i in range(10):
    time.sleep(0.2) 
    print ("\r Loading... {}".format(i)+str(i), end="")

The problem here is in your explode statement

//$item['date'] presumably = 20120514.  Do a print of this
$eventDate = trim($item['date']);

//This explodes on , but there is no , in $eventDate
//You also have a limit of 2 set in the below explode statement
$myarray = (explode(',', $eventDate, 2));

 //$myarray is currently = to '20'

 foreach ($myarray as $value) {
    //Now you are iterating through a string
    echo $value;
 }

Try changing your initial $item['date'] to be 2012,04,30 if that's what you're trying to do. Otherwise I'm not entirely sure what you're trying to print.

Just a note here that you may actually be better off having 3 separate SELECTS for reasons of optimization. If you have one single SELECT then the generated plan will have to project all columns col1, col2, col3, col7, col8 etc, although, depending on the value of the runtime @var, only some are needed. This may result in plans that do unnecessary clustered index lookups because the non-clustered index Doesn't cover all columns projected by the SELECT.

On the other hand 3 separate SELECTS, each projecting the needed columns only may benefit from non-clustered indexes that cover just your projected column in each case.

Of course this depends on the actual schema of your data model and the exact queries, but this is just a heads up so you don't bring the imperative thinking mind frame of procedural programming to the declarative world of SQL.

Make sure to check your version of npm and whether or not there are issues with it. I was having the same issue at the time of this post and I discovered that my npm version (6.5) was having issues. I had to uninstall and reinstall npm version 6.4.1 and then everything started to work great again.

Please Follow this process

First of all install git bash and create a repository on git

1) Go to working directory where the file exist which you want to push on remote and create .git folder by

$ git init

2) Add the files in your new local repository.

$ git add .

Note: while you are in same folder make sure you have placed dot after command if you putting path or not putting dot that will create ambiguity

3) Commit the files that you've staged in your local repository.

$ git commit -m "First commit"**

4) after this go to git repository and copy remote URL

$ git remote add origin *remote repository URL

5)

$ git remote -v

Note: this will ask for user.email and user.name just put it as per config

6)

$ git push origin master

this will push whole committed code to FILE.git on repository

And I think we done

There are a lot of right answers here depending on what you are trying to accomplish; here's my attempt at providing a comprehensive answer:

Both the Request and Response objects contain Cookies properties, which are HttpCookieCollection objects.

Request.Cookies:

• This collection contains cookies received from the client
• This collection is read-only
• If you attempt to access a non-existent cookie from this collection, you will receive a null value.

Response.Cookies:

• This collection contains only cookies that have been added by the server during the current request.
• This collection is writeable
• If you attempt to access a non-existent cookie from this collection, you will receive a new cookie object; If the cookie that you attempted to access DOES NOT exist in the Request.Cookies collection, it will be added (but if the Request.Cookies object already contains a cookie with the same key, and even if it's value is stale, it will not be updated to reflect the changes from the newly-created cookie in the Response.Cookies collection.

Solutions

If you want to check for the existence of a cookie from the client, do one of the following

• Request.Cookies["COOKIE_KEY"] != null
• Request.Cookies.Get("COOKIE_KEY") != null
• Request.Cookies.AllKeys.Contains("COOKIE_KEY")

If you want to check for the existence of a cookie that has been added by the server during the current request, do the following:

• Response.Cookies.AllKeys.Contains("COOKIE_KEY") (see here)

Attempting to check for a cookie that has been added by the server during the current request by one of these methods...

• Response.Cookies["COOKIE_KEY"] != null
• Response.Cookies.Get("COOKIE_KEY") != null (see here)

...will result in the creation of a cookie in the Response.Cookies collection and the state will evaluate to true.

The example in Liam's answer saves the file as string in a single line. I prefer to add formatting. Someone in the future may want to change some value manually in the file. If you add formatting it's easier to do so.

The following adds basic JSON indentation:

 string json = JsonConvert.SerializeObject(_data.ToArray(), Formatting.Indented);

This is how you do it

SELECT ID,NAME, (C_COUNTS+F_COUNTS) AS SUM_COUNTS 
FROM TABLE 
ORDER BY SUM_COUNTS LIMIT 20

The SUM function will add up all rows, so the order by clause is useless, instead you will have to use the group by clause.

Another quick and simple option...

import os

os.system('start path/to/player/executable path/to/file.mp3')

Now you might need to make some slight changes to make it work. For example, if the player needs extra arguments or you don't need to specify the full path. But this is a simple way of doing it.

Use the NSNumber method intValue

Here is simplified function which provides the added utility of returning depth (in case you want to use logic to include the parent task or search at a specific depth)

DELIMITER $$
FUNCTION `childDepth`(pParentId INT, pId INT) RETURNS int(11)
    READS SQL DATA
    DETERMINISTIC
BEGIN
DECLARE depth,curId int;
SET depth = 0;
SET curId = pId;

WHILE curId IS not null AND curId <> pParentId DO
    SELECT ParentId from test where id=curId limit 1 into curId;
    SET depth = depth + 1;
END WHILE;

IF curId IS NULL THEN
    set depth = -1;
END IF;

RETURN depth;
END$$

Usage:

select * from test where childDepth(1, id) <> -1;

This means that a TCP RST was received and the connection is now closed. This occurs when a packet is sent from your end of the connection but the other end does not recognize the connection; it will send back a packet with the RST bit set in order to forcibly close the connection.

This can happen if the other side crashes and then comes back up or if it calls close() on the socket while there is data from you in transit, and is an indication to you that some of the data that you previously sent may not have been received.

It is up to you whether that is an error; if the information you were sending was only for the benefit of the remote client then it may not matter that any final data may have been lost. However you should close the socket and free up any other resources associated with the connection.

It automates sorting and pagination a lot and gives you enough freedom to customize your table/list however you want.

It sounds as though you're not in a modern document mode. Internet Explorer 11 shows the SVG just fine when you're in Standards Mode. Make sure that if you have an x-ua-compatible meta tag, you have it set to Edge, rather than an earlier mode.

<meta http-equiv="X-UA-Compatible" content="IE=edge">

You can determine your document mode by opening up your F12 Developer Tools and checking either the document mode dropdown (seen at top-right, currently "Edge") or the emulation tab:

If you do not have an x-ua-compatible meta tag (or header), be sure to use a doctype that will put the document into Standards mode, such as <!DOCTYPE html>.

You can do it by RENAME statement for each table in your "current_db" after create the new schema "other_db"

RENAME TABLE current_db.tbl_name TO other_db.tbl_name

Thanks Yannis, your solution worked for me and here I'm sharing same solution for multiple keywords with order and limit.

A solution for gottcha for me, using Python's ElementTree... this has the invalid token error:

# -*- coding: utf-8 -*-
import xml.etree.ElementTree as ET

xml = u"""<?xml version='1.0' encoding='utf8'?>
<osm generator="pycrocosm server" version="0.6"><changeset created_at="2017-09-06T19:26:50.302136+00:00" id="273" max_lat="0.0" max_lon="0.0" min_lat="0.0" min_lon="0.0" open="true" uid="345" user="john"><tag k="test" v="????? ?? ??? ???? ?????? ??????????? ????? ?? ????? ???" /><tag k="foo" v="bar" /><discussion><comment data="2015-01-01T18:56:48Z" uid="1841" user="metaodi"><text>Did you verify those street names?</text></comment></discussion></changeset></osm>"""

xmltest = ET.fromstring(xml.encode("utf-8"))

However, it works with the addition of a hyphen in the encoding type:

<?xml version='1.0' encoding='utf-8'?>

Most odd. Someone found this footnote in the python docs:

The encoding string included in XML output should conform to the appropriate standards. For example, “UTF-8” is valid, but “UTF8” is not.

You'll need a PDF API for C#. iTextSharp is one possible API, though better ones might exist.

iTextSharp Example

You must install iTextSharp.dll as a reference. Download iTextsharp from SourceForge.net This is a complete working program using a console application.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using iTextSharp.text.pdf;
using iTextSharp.text.xml;
namespace GetPages_PDF
{
  class Program
{
    static void Main(string[] args)
      {
       // Right side of equation is location of YOUR pdf file
        string ppath = "C:\\aworking\\Hawkins.pdf";
        PdfReader pdfReader = new PdfReader(ppath);
        int numberOfPages = pdfReader.NumberOfPages;
        Console.WriteLine(numberOfPages);
        Console.ReadLine();

If you are trying to use javascript to avoid using SSL, think again. There are many half-way measures, but only SSL provides secure communication. Javascript encryption libraries can help against a certain set of attacks, but not a true man-in-the-middle attack.

The following article explains how to attempt to create secure communication with javascript, and how to get it wrong: Use JavaScript encryption module instead of SSL/HTTPS

Note: If you are looking for SSL for google app engine on a custom domain, take a look at wwwizer.com.

I would also like to point out that in case you are using command line arguments as part of a shell script (.sh file), then within the script, you would need to enclose the argument in quotes. So if your command looks like

>scriptName.sh arg1 arg2

And arg1 is your path that has spaces, then within the shell script, you would need to refer to it as "$arg1" instead of $arg1

Here are the details

You cannot display an application window/dialog through a Context that is not an Activity. Try passing a valid activity reference

The base dn is dc=example,dc=com.

I don't know about openca, but I will try this answer since you got very little traffic so far.

A base dn is the point from where a server will search for users. So I would try to simply use admin as a login name.

If openca behaves like most ldap aware applications, this is what is going to happen :

1. An ldap search for the user admin will be done by the server starting at the base dn (dc=example,dc=com).
2. When the user is found, the full dn (cn=admin,dc=example,dc=com) will be used to bind with the supplied password.
3. The ldap server will hash the password and compare with the stored hash value. If it matches, you're in.

Getting step 1 right is the hardest part, but mostly because we don't get to do it often. Things you have to look out for in your configuraiton file are :

• The dn your application will use to bind to the ldap server. This happens at application startup, before any user comes to authenticate. You will have to supply a full dn, maybe something like cn=admin,dc=example,dc=com.
• The authentication method. It is usually a "simple bind".
• The user search filter. Look at the attribute named objectClass for your admin user. It will be either inetOrgPerson or user. There will be others like top, you can ignore them. In your openca configuration, there should be a string like (objectClass=inetOrgPerson). Whatever it is, make sure it matches your admin user's object Class. You can specify two object class with this search filter (|(objectClass=inetOrgPerson)(objectClass=user)).

Download an LDAP Browser, such as Apache's Directory Studio. Connect using your application's credentials, so you will see what your application sees.

I just had the same problem and discovered an alternative solution using the validation API - works without black magic in all major browsers (Chrome, Firefox, Safari) except IE. This solution simply prevents users from entering invalid values. I also included a fallback for IE, which is not nice but works at least.

Context: onInput function is called on input events, setInputValue is used to set the value of the input element, previousInputValue contains the last valid input value (updated in setInputValue calls).

    function onInput (event) {
        const inputValue = event.target.value;

        // badInput supported on validation api (except IE)
        // in IE it will be undefined, so we need strict value check
        const badInput = event.target.validity.badInput;

        // simply prevent modifying the value
        if (badInput === true) {
        // it's still possible to enter invalid values in an empty input, so we'll need this trick to prevent that

                    setInputValue('');
                }, 1);
            }
            return;

        if (badInput === false) {
            setInputValue(inputValue);
            return;
        }

        // fallback case for IE and other abominations

        // remove everything from the string expect numbers, point and comma
        // replace comma with points (parseFloat works only with points)
        let stringVal = String(inputValue)
            .replace(/([^0-9.,])/g, '')
            .replace(/,/g, '.');

        // remove all but first point
        const pointIndex = stringVal.indexOf('.');
        if (pointIndex !== -1) {
            const pointAndBefore = stringVal.substring(0, pointIndex + 1);
            const afterPoint = stringVal.substring(pointIndex + 1);

            // removing all points after the first
            stringVal = `${pointAndBefore}${afterPoint.replace(/\./g, '')}`;
        }

        const float = parseFloat(stringVal);
        if (isNaN(float)) {
            // fallback to emptying the input if anything goes south
            setInputValue('');
            return;
        }
        setInputValue(stringVal);
}

Java 9

public static void main(String[] args) {
    Map<Integer,String> map = Map.ofEntries(entry(1,"A"), entry(2,"B"), entry(3,"C"));
}

Archive libraries (.a) are statically linked i.e when you compile your program with -c option in gcc. So, if there's any change in library, you need to compile and build your code again.

The advantage of .so (shared object) over .a library is that they are linked during the runtime i.e. after creation of your .o file -o option in gcc. So, if there's any change in .so file, you don't need to recompile your main program. But make sure that your main program is linked to the new .so file with ln command.

This will help you to build the .so files. http://www.yolinux.com/TUTORIALS/LibraryArchives-StaticAndDynamic.html

Hope this helps.

Swift 4.2+

Starting with Swift 4.2 (with Xcode 10), just add protocol conformance to CaseIterable to benefit from allCases. To add this protocol conformance, you simply need to write somewhere:

extension Suit: CaseIterable {}

If the enum is your own, you may specify the conformance directly in the declaration:

enum Suit: String, CaseIterable { case spades = "?"; case hearts = "?"; case diamonds = "?"; case clubs = "?" }

Then the following code will print all possible values:

Suit.allCases.forEach {
    print($0.rawValue)
}

Compatibility with earlier Swift versions (3.x and 4.x)

If you need to support Swift 3.x or 4.0, you may mimic the Swift 4.2 implementation by adding the following code:

#if !swift(>=4.2)
public protocol CaseIterable {
    associatedtype AllCases: Collection where AllCases.Element == Self
    static var allCases: AllCases { get }
}
extension CaseIterable where Self: Hashable {
    static var allCases: [Self] {
        return [Self](AnySequence { () -> AnyIterator<Self> in
            var raw = 0
            var first: Self?
            return AnyIterator {
                let current = withUnsafeBytes(of: &raw) { $0.load(as: Self.self) }
                if raw == 0 {
                    first = current
                } else if current == first {
                    return nil
                }
                raw += 1
                return current
            }
        })
    }
}
#endif

If you're trying to do stuff with the Java default system keystore (cacerts), then the default password is changeit.

You can list keys without needing the password (even if it prompts you) so don't take that as an indication that it is blank.

(Incidentally who in the history of Java ever has changed the default keystore password? They should have left it blank.)

Maybe the span element is hidden. If that's the case then use the innerHtml property:

By.css:

String kk = wd.findElement(By.cssSelector("#customSelect_3 span.selectLabel"))
              .getAttribute("innerHTML");

By.xpath:

String kk = wd.findElement(By.xpath(
                   "//*[@id='customSelect_3']/.//span[contains(@class,'selectLabel')]"))
              .getAttribute("innerHTML");

"/.//" means "look under the selected element".

The Answer from AaronM using the shell one-liner is good, but actually, there is yet another bug, where spaces will corrupt the user names if there are different amounts of white spaces between the user name and the date. The corrupted user names will give multiple rows for user counts and you have to sum them up yourself.

This small change fixed the issue for me:

git ls-files -z | xargs -0n1 git blame -w --show-email | perl -n -e '/^.*?\((.*?)\s+[\d]{4}/; print $1,"\n"' | sort -f | uniq -c | sort -n

Notice the + after \s which will consume all whitespaces from the name to the date.

Actually adding this answer as much for my own rememberance as for helping anyone else, since this is at least the second time I google the subject :)

• Edit 2019-01-23 Added --show-email to git blame -w to aggregate on email instead, since some people use different Name formats on different computers, and sometimes two people with the same name are working in the same git.

Correct Xpath syntax is like:

//tagname[@value='name']

So you should write something like this:

findElement(By.xpath("//input[@test-id='test-username']"));

Using UNION automatically removes duplicate rows unless you specify UNION ALL: http://msdn.microsoft.com/en-us/library/ms180026(SQL.90).aspx

U may do as I have written from my deleted account (ban for new posts :( there was). Its rather simple and nice looking.

Im using 3-rd one of these 3 ones usually, also I wasny checking 1 and 2 version.

from matplotlib.pyplot import cm
import numpy as np

#variable n should be number of curves to plot (I skipped this earlier thinking that it is obvious when looking at picture - sorry my bad mistake xD): n=len(array_of_curves_to_plot)
#version 1:

color=cm.rainbow(np.linspace(0,1,n))
for i,c in zip(range(n),color):
   ax1.plot(x, y,c=c)

#or version 2: - faster and better:

color=iter(cm.rainbow(np.linspace(0,1,n)))
c=next(color)
plt.plot(x,y,c=c)

#or version 3:

color=iter(cm.rainbow(np.linspace(0,1,n)))
for i in range(n):
   c=next(color)
   ax1.plot(x, y,c=c)

example of 3:

Ship RAO of Roll vs Ikeda damping in function of Roll amplitude A44

The getPosts() function seems to be expecting $con to be global, but you're not declaring it as such.

A lot of programmers regard bald global variables as a "code smell". The alternative at the other end of the scale is to always pass around the connection resource. Partway between the two is a singleton call that always returns the same resource handle.

The other solutions posted here didn't work for me, because:

• i just needed parameters from a file for a normal script
• import * didn't work for me, as i need a way to override them by choosing another file
• Just a file with a dict wasn't fine, as I needed comments in it.

So I ended up using Configparser and globals().update()

Test file:

#File parametertest.cfg:
[Settings]
#Comments are no Problem
test= True
bla= False    #Here neither

#that neither

And that's my demo script:

import ConfigParser

cfg = ConfigParser.RawConfigParser()
cfg.read('parametertest.cfg')       # Read file

#print cfg.getboolean('Settings','bla') # Manual Way to acess them

par=dict(cfg.items("Settings"))
for p in par:
    par[p]=par[p].split("#",1)[0].strip() # To get rid of inline comments

globals().update(par)  #Make them availible globally

print bla

It's just for a file with one section now, but that will be easy to adopt.

Hope it will be helpful for someone :)

If all you want is just too see the the swagger doc file (say swagger.json) in swagger UI, try open-swagger-ui (is essentially, open "in" swagger ui).

open-swagger-ui ./swagger.json --open

Please try with this

 $pattern = "/My name is '\(.*\)' and im fine/"; 

I know this is an old post, but figured I'd share my two cents. @Neji is correct in that you can use sessionStorage.getItem('label'), and sessionStorage.setItem('label', 'value') (although he had the setItem parameters backwards, not a big deal). I much more prefer the following, I think it's more succinct:

var val = sessionStorage.myValue

in place of getItem and

sessionStorage.myValue = 'value'

in place of setItem.

Also, it should be noted that in order to store JavaScript objects, they must be stringified to set them, and parsed to get them, like so:

sessionStorage.myObject = JSON.stringify(myObject); //will set object to the stringified myObject
var myObject = JSON.parse(sessionStorage.myObject); //will parse JSON string back to object

The reason is that sessionStorage stores everything as a string, so if you just say sessionStorage.object = myObject all you get is [object Object], which doesn't help you too much.

I was inspired by Thejuan's answer to write a simpler attached property. No styles, no triggers; instead, you can just do this:

<Window ...
        xmlns:xc="clr-namespace:ExCastle.Wpf"
        xc:DialogCloser.DialogResult="{Binding DialogResult}">

This is almost as clean as if the WPF team had gotten it right and made DialogResult a dependency property in the first place. Just put a bool? DialogResult property on your ViewModel and implement INotifyPropertyChanged, and voilà, your ViewModel can close the Window (and set its DialogResult) just by setting a property. MVVM as it should be.

Here's the code for DialogCloser:

using System.Windows;

namespace ExCastle.Wpf
{
    public static class DialogCloser
    {
        public static readonly DependencyProperty DialogResultProperty =
            DependencyProperty.RegisterAttached(
                "DialogResult",
                typeof(bool?),
                typeof(DialogCloser),
                new PropertyMetadata(DialogResultChanged));

        private static void DialogResultChanged(
            DependencyObject d,
            DependencyPropertyChangedEventArgs e)
        {
            var window = d as Window;
            if (window != null)
                window.DialogResult = e.NewValue as bool?;
        }
        public static void SetDialogResult(Window target, bool? value)
        {
            target.SetValue(DialogResultProperty, value);
        }
    }
}

I've also posted this on my blog.

Use ifelse:

frame$twohouses <- ifelse(frame$data>=2, 2, 1)
frame
   data twohouses
1     0         1
2     1         1
3     2         2
4     3         2
5     4         2
...
16    0         1
17    2         2
18    1         1
19    2         2
20    0         1
21    4         2

The difference between if and ifelse:

• if is a control flow statement, taking a single logical value as an argument
• ifelse is a vectorised function, taking vectors as all its arguments.

The help page for if, accessible via ?"if" will also point you to ?ifelse

<input type="number" @bind="Quantity" class="txt2" />

Use the type="number"

For me logging in as -Y instead of -X worked.

In case you've got untrusted X11 as shown below, then try -Y flag instead (if you trust the host):

Warning: untrusted X11 forwarding setup failed: xauth key data not generated

My problem was that I had a list of numbers, and I only want to replace a part of that number, soy I do this:

original_list = ['08113', '09106', '19066', '17056', '17063', '17053']

# With this part I achieve my goal
cves_mod = []
for i in range(0,len(res_list)):
    cves_mod.append(res_list[i].replace(res_list[i][2:], '999'))
cves_mod

# Result
cves_mod
['08999', '09999', '19999', '17999', '17999', '17999']

I used the jQuery slim version and got this error. By using the normal jQuery version the issue got resolved.

As an alternative to the other answers, it's possible to do this with a syntax similar to the way you originally intended if you do it via a case statement rather than an if:

session := Session{}
switch {
case Session{} == session:
    fmt.Println("zero")
default:
    fmt.Println("not zero")
}

playground example

Here is example of grid system with material-ui which is similar to bootstrap:

<Grid container>
    <Grid item xs={12} sm={4} md={4} lg={4}>
    </Grid>
    <Grid item xs={12} sm={4} md={4} lg={4}>
    </Grid>
 </Grid>

CARL LANGE also showed how to get hidden, autoplaying audio in html5 on a iOS device. Works for me.

In HTML,

<div id="hideme">
    <audio id="audioTag" controls>
        <source src="/path/to/audio.mp3">
    </audio>
</div>

with JS

<script type="text/javascript">
window.onload = function() {
    var audioEl = document.getElementById("audioTag");
    audioEl.load();
    audioEl.play();
};
</script>

In CSS,

#hideme {display: none;}

To elaborate on @Bakuriu's answer above, I've found that this enables me to catch a runtime warning in a similar fashion to how I would catch an error warning, printing out the warning nicely:

import warnings

with warnings.catch_warnings():
    warnings.filterwarnings('error')
    try:
        answer = 1 / 0
    except Warning as e:
        print('error found:', e)

You will probably be able to play around with placing of the warnings.catch_warnings() placement depending on how big of an umbrella you want to cast with catching errors this way.

do this 2 steps: 1. in this menu: project -> yourproject properties... -> Build : uncheck "prefer 32-Bit" 2. in connectionString : write cuotes before and after Extended properties, like this: Extended Properties='Excel 12.0 Xml;HDR=YES'

                var fileName = string.Format("{0}", openFileDialog1.FileName);
            //var connectionString = string.Format("Provider=Microsoft.Jet.OLEDB.4.0; data source={0}; Extended Properties=Excel 8.0;", fileName);
            var connectionString = string.Format("Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0}; Extended Properties='Excel 12.0 Xml;HDR=YES'", fileName);
            var adapter = new OleDbDataAdapter("SELECT * FROM [Sheet1$]", connectionString);
            var ds = new DataSet();

            adapter.Fill(ds, TableNmae);

            DataTable data = ds.Tables[TableNmae];
            dg1.DataSource = data;

Updated answer for how to find which version of Swift your project is using in a few click in Xcode 12 to help out rookies like me.

1. Click on your Project (top level Blue Icon in the left hand pane)
2. Click on Build Settings (5th item in the Project > Header)
3. Scroll down to Swift Compiler - Language, and look at the dropdown.

>>> test
array([[0, 1, 2, 3, 4],
       [5, 6, 7, 8, 9]])

>>> ncol = test.shape[1]
>>> ncol
5L

Then you can select the 2nd - 4th column this way:

>>> test[0:, 1:(ncol - 1)]
array([[1, 2, 3],
       [6, 7, 8]])

Try this:

jquery

    $('#save-source').click(function (e) {
        e.preventDefault();
        var source = {
            'ID': 0,
            //'ProductID': $('#ID').val(),
            'PartNumber': $('#part-number').val(),
            //'VendorID': $('#Vendors').val()
        }
        $.ajax({
            type: "POST",
            dataType: "json",
            url: "/api/PartSourceAPI",
            data: source,
            success: function (data) {
                alert(data);
            },
            error: function (error) {
                jsonValue = jQuery.parseJSON(error.responseText);
                //jError('An error has occurred while saving the new part source: ' + jsonValue, { TimeShown: 3000 });
            }
        });
    });

Controller

    public string Post(PartSourceModel model)
    {
        return model.PartNumber;
    }

View

<label>Part Number</label>
<input type="text" id="part-number" name="part-number" />

<input type="submit" id="save-source" name="save-source" value="Add" />

Now when you click 'Add' after you fill out the text box, the controller will spit back out what you wrote in the PartNumber box in an alert.

GriffeyDog is definitely correct:

Code:

BigDecimal myBigDecimal = new BigDecimal("00000000.000000");
System.out.println("bestPriceBigDecimal=" + myBigDecimal);
System.out.println("BigDecimal.valueOf(0.000000)=" + BigDecimal.valueOf(0.000000));
System.out.println(" equals=" + myBigDecimal.equals(BigDecimal.ZERO));
System.out.println("compare=" + (0 == myBigDecimal.compareTo(BigDecimal.ZERO)));

Results:

myBigDecimal=0.000000
BigDecimal.valueOf(0.000000)=0.0
 equals=false
compare=true

While I understand the advantages of the BigDecimal compare, I would not consider it an intuitive construct (like the ==, <, >, <=, >= operators are). When you are holding a million things (ok, seven things) in your head, then anything you can reduce your cognitive load is a good thing. So I built some useful convenience functions:

public static boolean equalsZero(BigDecimal x) {
    return (0 == x.compareTo(BigDecimal.ZERO));
}
public static boolean equals(BigDecimal x, BigDecimal y) {
    return (0 == x.compareTo(y));
}
public static boolean lessThan(BigDecimal x, BigDecimal y) {
    return (-1 == x.compareTo(y));
}
public static boolean lessThanOrEquals(BigDecimal x, BigDecimal y) {
    return (x.compareTo(y) <= 0);
}
public static boolean greaterThan(BigDecimal x, BigDecimal y) {
    return (1 == x.compareTo(y));
}
public static boolean greaterThanOrEquals(BigDecimal x, BigDecimal y) {
    return (x.compareTo(y) >= 0);
}

Here is how to use them:

    System.out.println("Starting main Utils");
    BigDecimal bigDecimal0 = new BigDecimal(00000.00);
    BigDecimal bigDecimal2 = new BigDecimal(2);
    BigDecimal bigDecimal4 = new BigDecimal(4);  
    BigDecimal bigDecimal20 = new BigDecimal(2.000);
    System.out.println("Positive cases:");
    System.out.println("bigDecimal0=" + bigDecimal0 + " == zero is " + Utils.equalsZero(bigDecimal0));
    System.out.println("bigDecimal2=" + bigDecimal2 + " <  bigDecimal4=" + bigDecimal4 + " is " + Utils.lessThan(bigDecimal2, bigDecimal4));
    System.out.println("bigDecimal2=" + bigDecimal2 + " == bigDecimal20=" + bigDecimal20 + " is " + Utils.equals(bigDecimal2, bigDecimal20));
    System.out.println("bigDecimal2=" + bigDecimal2 + " <= bigDecimal20=" + bigDecimal20 + " is " + Utils.equals(bigDecimal2, bigDecimal20));
    System.out.println("bigDecimal2=" + bigDecimal2 + " <= bigDecimal4=" + bigDecimal4 + " is " + Utils.lessThanOrEquals(bigDecimal2, bigDecimal4));
    System.out.println("bigDecimal4=" + bigDecimal4 + " >  bigDecimal2=" + bigDecimal2 + " is " + Utils.greaterThan(bigDecimal4, bigDecimal2));
    System.out.println("bigDecimal4=" + bigDecimal4 + " >= bigDecimal2=" + bigDecimal2 + " is " + Utils.greaterThanOrEquals(bigDecimal4, bigDecimal2));
    System.out.println("bigDecimal2=" + bigDecimal2 + " >= bigDecimal20=" + bigDecimal20 + " is " + Utils.greaterThanOrEquals(bigDecimal2, bigDecimal20));
    System.out.println("Negative cases:");
    System.out.println("bigDecimal2=" + bigDecimal2 + " == zero is " + Utils.equalsZero(bigDecimal2));
    System.out.println("bigDecimal2=" + bigDecimal2 + " == bigDecimal4=" + bigDecimal4 + " is " + Utils.equals(bigDecimal2, bigDecimal4));
    System.out.println("bigDecimal4=" + bigDecimal4 + " <  bigDecimal2=" + bigDecimal2 + " is " + Utils.lessThan(bigDecimal4, bigDecimal2));
    System.out.println("bigDecimal4=" + bigDecimal4 + " <= bigDecimal2=" + bigDecimal2 + " is " + Utils.lessThanOrEquals(bigDecimal4, bigDecimal2));
    System.out.println("bigDecimal2=" + bigDecimal2 + " >  bigDecimal4=" + bigDecimal4 + " is " + Utils.greaterThan(bigDecimal2, bigDecimal4));
    System.out.println("bigDecimal2=" + bigDecimal2 + " >= bigDecimal4=" + bigDecimal4 + " is " + Utils.greaterThanOrEquals(bigDecimal2, bigDecimal4));

The results look like this:

Positive cases:
bigDecimal0=0 == zero is true
bigDecimal2=2 <  bigDecimal4=4 is true
bigDecimal2=2 == bigDecimal20=2 is true
bigDecimal2=2 <= bigDecimal20=2 is true
bigDecimal2=2 <= bigDecimal4=4 is true
bigDecimal4=4 >  bigDecimal2=2 is true
bigDecimal4=4 >= bigDecimal2=2 is true
bigDecimal2=2 >= bigDecimal20=2 is true
Negative cases:
bigDecimal2=2 == zero is false
bigDecimal2=2 == bigDecimal4=4 is false
bigDecimal4=4 <  bigDecimal2=2 is false
bigDecimal4=4 <= bigDecimal2=2 is false
bigDecimal2=2 >  bigDecimal4=4 is false
bigDecimal2=2 >= bigDecimal4=4 is false

Swift 3:

extension URL {
    func getQueryItemValueForKey(key: String) -> String? {
        guard let components = NSURLComponents(url: self, resolvingAgainstBaseURL: false) else {
              return nil
        }

        guard let queryItems = components.queryItems else { return nil }
     return queryItems.filter {
                 $0.name.lowercased() == key.lowercased()
                 }.first?.value
    }
}

I used it to get the image name for UIImagePickerController in func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]):

var originalFilename = ""
if let url = info[UIImagePickerControllerReferenceURL] as? URL, let imageIdentifier = url.getQueryItemValueForKey(key: "id") {
    originalFilename = imageIdentifier + ".png"
    print("file name : \(originalFilename)")
}

There are two ways to go about this:

I recommend the first option initially, due to its ease of implementation. Once you mature in your build processes, switch over to the second.

1. Poll the repository to see if changes occurred. This might "skip" a commit if two commits come in within the same polling interval. Description of how to do so here, note the fourth screenshot where you configure on the job a "build trigger" based on polling the repository (with a crontab-like configuration).

2. Configure your repository to have a post-commit hook which notifies Jenkins that a build needs to start. Description of how to do so here, in the section "post-commit hooks"

The SVN Tag feature is not part of the polling, it is part of promoting the current "head" of the source code to a tag, to snapshot a build. This allows you to refer to Jenkins buid #32 as SVN tag /tags/build-32 (or something similar).

The same instance for SP2010; the Links List webpart will not automatically open in a new window, rather user must manually rt click Link object and select Open in New Window.

The add/ insert Link option withkin SP2010 will allow a user to manually configure the link to open in a new window.

Maybe SP2012 release will adrress this...

Sometimes, the minimal installation of Linux in Docker doesn't define the path and therefore it is necessary to call ping using ....

cd /usr/sbin
ping <ip>

It means a call to a virtual function will be forwarded to the "right" class.

C++ FAQ Lite FTW.

In short, it is often used in multiple-inheritance scenarios, where a "diamond" hierarchy is formed. Virtual inheritance will then break the ambiguity created in the bottom class, when you call function in that class and the function needs to be resolved to either class D1 or D2 above that bottom class. See the FAQ item for a diagram and details.

It is also used in sister delegation, a powerful feature (though not for the faint of heart). See this FAQ.

Also see Item 40 in Effective C++ 3rd edition (43 in 2nd edition).

Try this:

window.open(url, '_blank');

This will open in new tab (if your code is synchronous and in this case it is. in other case it would open a window)

You are doing everything right, except passing your bundle path to asset() function.

According to documentation - in your example this should look like below:

{{ asset('bundles/webshome/css/main.css') }}

Tip: you also can call assets:install with --symlink key, so it will create symlinks in web folder. This is extremely useful when you often apply js or css changes (in this way your changes, applied to src/YouBundle/Resources/public will be immediately reflected in web folder without need to call assets:install again):

app/console assets:install web --symlink

Also, if you wish to add some assets in your child template, you could call parent() method for the Twig block. In your case it would be like this:

{% block stylesheets %}
    {{ parent() }}

    <link href="{{ asset('bundles/webshome/css/main.css') }}" rel="stylesheet">
{% endblock %}

You can use strptime(3) to parse the time, and then mktime(3) to convert it to a time_t:

const char *time_details = "16:35:12";
struct tm tm;
strptime(time_details, "%H:%M:%S", &tm);
time_t t = mktime(&tm);  // t is now your desired time_t

select sq.PARSING_SCHEMA_NAME, sq.LAST_LOAD_TIME, sq.ELAPSED_TIME, sq.ROWS_PROCESSED, ltrim(sq.sql_text), sq.SQL_FULLTEXT
  from v$sql sq, v$session se
 order by sq.ELAPSED_TIME desc, sq.LAST_LOAD_TIME desc;

There is no reliable way to check this. It's really under client's hand to tell you where it came from. You could imagine to use cookie or sessions informations put only on some pages of your website, but doing so your would break user experience with bookmarks.

"End Process" on the Processes-Tab calls TerminateProcess which is the most ultimate way Windows knows to kill a process.

If it doesn't go away, it's currently locked waiting on some kernel resource (probably a buggy driver) and there is nothing (short of a reboot) you could do to make the process go away.

Have a look at this blog-entry from wayback when: http://blogs.technet.com/markrussinovich/archive/2005/08/17/unkillable-processes.aspx

Unix based systems like Linux also have that problem where processes could survive a kill -9 if they are in what's known as "Uninterruptible sleep" (shown by top and ps as state D) at which point the processes sleep so well that they can't process incoming signals (which is what kill does - sending signals).

Normally, Uninterruptible sleep should not last long, but as under Windows, broken drivers or broken userpace programs (vfork without exec) can end up sleeping in D forever.

In Servlet do:

String selectedRole = "rat"; // Or "cat" or whatever you'd like.
request.setAttribute("selectedRole", selectedRole);

Then in JSP do:

<select name="roleName">
    <c:forEach items="${roleNames}" var="role">
        <option value="${role}" ${role == selectedRole ? 'selected' : ''}>${role}</option>
    </c:forEach>
</select>

It will print the selected attribute of the HTML <option> element so that you end up like:

<select name="roleName">
    <option value="cat">cat</option>
    <option value="rat" selected>rat</option>
    <option value="unicorn">unicorn</option>
</select>

Apart from the problem: this is not a combo box. This is a dropdown. A combo box is an editable dropdown.

Try this instead.

<Window x:Class="BuildAssistantUI.BuildAssistantWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:VM="clr-namespace:BuildAssistantUI.ViewModels">
    <Window.DataContext>
        <VM:MainViewModel />
    </Window.DataContext>
</Window>

Actually, you are looking for the AJAX CALL, in which you will replace the URL parameter value with the link of the JSON file to get the JSON values.

$.ajax({
    url: "File.json", //the path of the file is replaced by File.json
    dataType: "json",
    success: function (response) {
        console.log(response); //it will return the json array
    }
});

import binascii

binascii.a2b_hex(hex_string)

Thats the way I did it.

Just use the --jars parameter. Spark will share those jars (comma-separated) with the executors.

you can use the "file" module in this case, there are so many arguments that you can pass for a newly created directory like the owner, group, location, mode and so on.....

please refer to this document for the detailed explanation on the file module...

https://docs.ansible.com/ansible/latest/modules/file_module.html#file-module

remember this module is not just for creating the directory !!!

echo Hello, > file.txt
echo.       >>file.txt
echo world  >>file.txt

and you can always run:

wordpad file.txt

on any version of Windows.

On Windows 2000 and above you can do:

( echo Hello, & echo. & echo world ) > file.txt

Another way of showing a message for a small amount of text is to create file.vbs containing:

Msgbox "Hello," & vbCrLf & vbCrLf & "world", 0, "Message"

Call it with

cscript /nologo file.vbs

Or use wscript if you don't need it to wait until they click OK.

The problem with the message you're writing is that the vertical bar (|) is the "pipe" operator. You'll need to escape it by using ^| instead of |.

P.S. it's spelled Pwned.

If you have a fixed width element and know the width of your background image, you can simply set the background-position to : the element's width - the image's width - the gap you want on the right.

For example : with a 100px-wide element and a 300px-wide image, to get a gap of 10px on the right, you set it to 100-300-10=-210px :

#myElement {
  background:url(my_image.jpg) no-repeat -210px top;
  width:100px;
}

And you get the rightmost 80 pixels of your image on the left of your element, and a gap of 20px on the right.

I know it can sound stupid but sometimes it saves the time... I use that much in a vertical manner (gap at bottom) for navigation links with text below image.

Not sure it applies to your case though.
