If you want to get an index about the similarity of the two pictures, I suggest you from the metrics the SSIM index. It is more consistent with the human eye. Here is an article about it: Structural Similarity Index

It is implemented in OpenCV too, and it can be accelerated with GPU: OpenCV SSIM with GPU

Two popular and relatively simple methods are: (a) the Euclidean distance already suggested, or (b) normalized cross-correlation. Normalized cross-correlation tends to be noticeably more robust to lighting changes than simple cross-correlation. Wikipedia gives a formula for the normalized cross-correlation. More sophisticated methods exist too, but they require quite a bit more work.

Using numpy-like syntax,

dist_euclidean = sqrt(sum((i1 - i2)^2)) / i1.size

dist_manhattan = sum(abs(i1 - i2)) / i1.size

dist_ncc = sum( (i1 - mean(i1)) * (i2 - mean(i2)) ) / (
  (i1.size - 1) * stdev(i1) * stdev(i2) )

assuming that i1 and i2 are 2D grayscale image arrays.

Ceiling is the command you want to use.

Unlike Round, Ceiling only takes one parameter (the value you wish to round up), therefore if you want to round to a decimal place, you will need to multiply the number by that many decimal places first and divide afterwards.

Example.

I want to round up 1.2345 to 2 decimal places.

CEILING(1.2345*100)/100 AS Cost

If you use ThreadPoolExecutor, and you use submit() method, it will give you a Future back. You can call cancel() on the returned Future to stop your Runnable task.

Use position:fixed this way your div will remain over the whole viewable area continuously ..

give your div a class overlay and create the following rule in your CSS

.overlay{
    opacity:0.8;
    background-color:#ccc;
    position:fixed;
    width:100%;
    height:100%;
    top:0px;
    left:0px;
    z-index:1000;
}

private dynamic defaultReminder = reminder.TimeSpanText[TimeSpan.FromMinutes(15)]; is a field initializer and executes first (before any field without an initializer is set to its default value and before the invoked instance constructor is executed). Instance fields that have no initializer will only have a legal (default) value after all instance field initializers are completed. Due to the initialization order, instance constructors are executed last, which is why the instance is not created yet the moment the initializers are executed. Therefore the compiler cannot allow any instance property (or field) to be referenced before the class instance is fully constructed. This is because any access to an instance variable like reminder implicitly references the instance (this) to tell the compiler the concrete memory location of the instance to use.

This is also the reason why this is not allowed in an instance field initializer.

A variable initializer for an instance field cannot reference the instance being created. Thus, it is a compile-time error to reference this in a variable initializer, as it is a compile-time error for a variable initializer to reference any instance member through a simple_name.

The only type members that are guaranteed to be initialized before instance field initializers are executed are class (static) field initializers and class (static) constructors and class methods. Since static members are instance independent, they can be referenced at any time:

class SomeOtherClass
{
  private static Reminders reminder = new Reminders();

  // This operation is allowed,
  // since the compiler can guarantee that the referenced class member is already initialized
  // when this instance field initializer executes
  private dynamic defaultReminder = reminder.TimeSpanText[TimeSpan.FromMinutes(15)];
}

That's why instance field initializers are only allowed to reference a class member (static member). This compiler initialization rules will ensure a deterministic type instantiation.

For more details I recommend this document: Microsoft Docs: Class declarations.

This means that an instance field that references another instance member to initialize its value, must be initialized from the instance constructor or the referenced member must be declared static.

In some systems one have to specify:

import os
os.environ["CUDA_DEVICE_ORDER"]="PCI_BUS_ID"
os.environ["CUDA_VISIBLE_DEVICES"]=""  # or even "-1"

On Debian (Wheezy, 7.8) with MySQL 5.5.40, I found SELECT * FROM mysql.user WHERE User='root'\G showed the Event_priv and 'Trigger_priv` fields were present but not set to Y.

Running mysql_upgrade (with or without --force) made no difference; I needed to do a manual:

update user set Event_priv = 'Y',Trigger_priv = 'Y' where user = 'root'

Then finally I could use:

GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY 'password' WITH GRANT OPTION

…and then use it more precisely on an individual database/user account.

you can also use .between() method

emp = pd.read_csv("C:\\py\\programs\\pandas_2\\pandas\\employees.csv")

emp[emp["Salary"].between(60000, 61000)]

Output

Here is how I create a tag:

private static final String TAG = SomeActivity.class.getSimpleName();
 Log.d(TAG, "some description");

You could use getCannonicalName

Here I have following TAG filters:

• any (*) View - VERBOSE
• any (*) Activity - VERBOSE
• any tag starting with Xyz(*) - ERROR
• System.out - SILENT (since I am using Log in my own code)

Here what I type in terminal:

$  adb logcat *View:V *Activity:V Xyz*:E System.out:S

You get a recursion error because your attempt to access the self.__dict__ attribute inside __getattribute__ invokes your __getattribute__ again. If you use object's __getattribute__ instead, it works:

class D(object):
    def __init__(self):
        self.test=20
        self.test2=21
    def __getattribute__(self,name):
        if name=='test':
            return 0.
        else:
            return object.__getattribute__(self, name)

This works because object (in this example) is the base class. By calling the base version of __getattribute__ you avoid the recursive hell you were in before.

Ipython output with code in foo.py:

In [1]: from foo import *

In [2]: d = D()

In [3]: d.test
Out[3]: 0.0

In [4]: d.test2

Update:

There's something in the section titled More attribute access for new-style classes in the current documentation, where they recommend doing exactly this to avoid the infinite recursion.

I know this thread is a little old but it came in handy for a specific scenario I had and I thought it worth while to note that there is another reason why System.Threading.Timer might be a good approach. When you have to periodically execute a Job that might take a long time and you want to ensure that the entire waiting period is used between jobs or if you don't want the job to run again before the previous job has finished in the case where the job takes longer than the timer period. You could use the following:

using System;
using System.ServiceProcess;
using System.Threading;

    public partial class TimerExampleService : ServiceBase
    {
        private AutoResetEvent AutoEventInstance { get; set; }
        private StatusChecker StatusCheckerInstance { get; set; }
        private Timer StateTimer { get; set; }
        public int TimerInterval { get; set; }

        public CaseIndexingService()
        {
            InitializeComponent();
            TimerInterval = 300000;
        }

        protected override void OnStart(string[] args)
        {
            AutoEventInstance = new AutoResetEvent(false);
            StatusCheckerInstance = new StatusChecker();

            // Create the delegate that invokes methods for the timer.
            TimerCallback timerDelegate =
                new TimerCallback(StatusCheckerInstance.CheckStatus);

            // Create a timer that signals the delegate to invoke 
            // 1.CheckStatus immediately, 
            // 2.Wait until the job is finished,
            // 3.then wait 5 minutes before executing again. 
            // 4.Repeat from point 2.
            Console.WriteLine("{0} Creating timer.\n",
                DateTime.Now.ToString("h:mm:ss.fff"));
            //Start Immediately but don't run again.
            StateTimer = new Timer(timerDelegate, AutoEventInstance, 0, Timeout.Infinite);
            while (StateTimer != null)
            {
                //Wait until the job is done
                AutoEventInstance.WaitOne();
                //Wait for 5 minutes before starting the job again.
                StateTimer.Change(TimerInterval, Timeout.Infinite);
            }
            //If the Job somehow takes longer than 5 minutes to complete then it wont matter because we will always wait another 5 minutes before running again.
        }

        protected override void OnStop()
        {
            StateTimer.Dispose();
        }
    }

    class StatusChecker
        {

            public StatusChecker()
            {
            }

            // This method is called by the timer delegate.
            public void CheckStatus(Object stateInfo)
            {
                AutoResetEvent autoEvent = (AutoResetEvent)stateInfo;
                Console.WriteLine("{0} Start Checking status.",
                    DateTime.Now.ToString("h:mm:ss.fff"));
                //This job takes time to run. For example purposes, I put a delay in here.
                int milliseconds = 5000;
                Thread.Sleep(milliseconds);
                //Job is now done running and the timer can now be reset to wait for the next interval
                Console.WriteLine("{0} Done Checking status.",
                    DateTime.Now.ToString("h:mm:ss.fff"));
                autoEvent.Set();
            }
        }

Useful sns.heatmap api is here. Check out the parameters, there are a good number of them. Example:

import seaborn as sns
%matplotlib inline

idx= ['aaa','bbb','ccc','ddd','eee']
cols = list('ABCD')
df = DataFrame(abs(np.random.randn(5,4)), index=idx, columns=cols)

# _r reverses the normal order of the color map 'RdYlGn'
sns.heatmap(df, cmap='RdYlGn_r', linewidths=0.5, annot=True)

If you use the command

time /T

that will print the time. (without the /T, it will try to set the time)

date /T

is similar for the date.

If cmd's Command Extensions are enabled (they are enabled by default, but in this question they appear to be disabled), then the environment variables %DATE% and %TIME% will expand to the current date and time each time they are expanded. The format used is the same as the DATE and TIME commands.

To see the other dynamic environment variables that exist when Command Extensions are enabled, run set /?.

This script logs all the file names and ids in the drive:

// Log the name and id of every file in the user's Drive
function listFiles() {
  var files = DriveApp.getFiles();
  while ( files.hasNext() ) {
    var file = files.next();
    Logger.log( file.getName() + ' ' + file.getId() );
  }
}  

Also, the "Files: list" page has a form at the end that lists the metadata of all the files in the drive, that can be used in case you need but a few ids.

Intelephense 1.3 added undefined type, function, constant, class constant, method, and property diagnostics, where previously in 1.2 there was only undefined variable diagnostics.

Some frameworks are written in a way that provide convenient shortcuts for the user but make it difficult for static analysis engines to discover symbols that are available at runtime.

Stub generators like https://github.com/barryvdh/laravel-ide-helper help fill the gap here and using this with Laravel will take care of many of the false diagnostics by providing concrete definitions of symbols that can be easily discovered.

Still, PHP is a very flexible language and there may be other instances of false undefined symbols depending on how code is written. For this reason, since 1.3.3, intelephense has config options to enable/disable each category of undefined symbol to suit the workspace and coding style.

These options are: intelephense.diagnostics.undefinedTypes intelephense.diagnostics.undefinedFunctions intelephense.diagnostics.undefinedConstants intelephense.diagnostics.undefinedClassConstants intelephense.diagnostics.undefinedMethods intelephense.diagnostics.undefinedProperties intelephense.diagnostics.undefinedVariables

Setting all of these to false except intelephense.diagnostics.undefinedVariables will give version 1.2 behaviour. See the VSCode settings UI and search for intelephense.

It does not work because sequence does not work in following scenarios:

• In a WHERE clause
• In a GROUP BY or ORDER BY clause
• In a DISTINCT clause
• Along with a UNION or INTERSECT or MINUS
• In a sub-query

Source: http://www.orafaq.com/wiki/ORA-02287

However this does work:

insert into table_name
            (col1, col2)
  select my_seq.nextval, inner_view.*
    from (select 'some value' someval
            from dual
          union all
          select 'another value' someval
            from dual) inner_view;

Try it out:

create table table_name(col1 varchar2(100), col2 varchar2(100));

create sequence vcert.my_seq
start with 1
increment by 1
minvalue 0;

select * from  table_name;

UIWebviews can also load the .pdf using loadData method, if you acquire it as NSData:

[self.webView loadData:self.pdfData 
              MIMEType:@"application/pdf" 
      textEncodingName:@"UTF-8" 
               baseURL:nil];

You could create a helper function to take care of that:

/**
 * Return string before needle if it exists.
 *
 * @param string $str
 * @param mixed $needle
 * @return string
 */
function str_before($str, $needle)
{
    $pos = strpos($str, $needle);

    return ($pos !== false) ? substr($str, 0, $pos) : $str;
}

Here's a use case:

$sing = 'My name is Luka. I live on the second floor.';

echo str_before($sing, '.'); // My name is Luka

Just ran into this issue - if you updated a bunch of files and don't want to do git mv all of them this also works:

1. Rename parent directory from /dir/RenamedFile.js to /whatever/RenamedFile.js.
2. git add -A to stage that change
3. Rename parent directory back to /dir/RenamedFile.js.
4. git add -A again, will re-stage vs that change, forcing git to pick up the filename change.

This is the fastest way:

if ($coll->isEmpty()) {...}

Other solutions like count do a bit more than you need which costs slightly more time.

Plus, the isEmpty() name quite precisely describes what you want to check there so your code will be more readable.

Here is my little utility helper for splitting paths int file, path tokens:

import os    
# usage: file, path = splitPath(s)
def splitPath(s):
    f = os.path.basename(s)
    p = s[:-(len(f))-1]
    return f, p

you need nested foreach loops

foreach($samplearr as $key => $item){
   echo $key;
    foreach($item as $detail){
       echo $detail['value1'] . " " . $detail['value2']
     }
 }

Here is a sample code with explanation.

 //Create a response instance
 $response = new Illuminate\Http\Response('Hello World');

 //Call the withCookie() method with the response method
 $response->withCookie(cookie('name', 'value', $minutes));

 //return the response
 return $response;

Cookie can be set forever by using the forever method as shown in the below code.

$response->withCookie(cookie()->forever('name', 'value'));

Retrieving a Cookie

//’name’ is the name of the cookie to retrieve the value of
$value = $request->cookie('name');

Be very careful when using find and sed in a git repo! If you don't exclude the binary files you can end up with this error:

error: bad index file sha1 signature 
fatal: index file corrupt

To solve this error you need to revert the sed by replacing your new_string with your old_string. This will revert your replaced strings, so you will be back to the beginning of the problem.

The correct way to search for a string and replace it is to skip find and use grep instead in order to ignore the binary files:

Blocking in Node.js is not necessary, even when developing tight hardware solutions. See temporal.js which does not use setTimeout or setIntervalsetImmediate. Instead, it uses setImmediate or nextTick which give much higher resolution task execution, and you can create a linear list of tasks. But you can do it without blocking the thread.

If you're using Java 8, the Arrays class provides a stream(int[] array) method which returns a sequential IntStream with the specified int array. It has also been overloaded for double and long arrays.

int [] arr = {1,2,3,4};
int sum = Arrays.stream(arr).sum(); //prints 10

It also provides a method stream(int[] array, int startInclusive, int endExclusive) which permits you to take a specified range of the array (which can be useful) :

int sum = Arrays.stream(new int []{1,2,3,4}, 0, 2).sum(); //prints 3

Finally, it can take an array of type T. So you can per example have a String which contains numbers as an input and if you want to sum them just do :

int sum = Arrays.stream("1 2 3 4".split("\\s+")).mapToInt(Integer::parseInt).sum();

Does this work?

Dim book As Workbook
Set book = Workbooks.Open(Filename:=filepath, ReadOnly:=True)

On mobile devices sending everything to the GPU will cause a memory overload and crash the application. I encountered this on an iPad app in Cordova. Best to only send the required items to the GPU, the divs that you're specifically moving around.

Better yet, use the 3d transitions transforms to do the animations like translateX(50px) as opposed to left:50px;

In my case, I just was mistaking about project credentials: using google-services.json from one project, and server key from another.

Resolution fix: For me, the problem was related to active chrome sessions. I closed all of my chrome browser sessions and then tried building to chrome again. I am using Visual Studio Professional 2017 version 15.3.2. The VS application I was running into build errors with was a WebAPI project. When trying to click the green play button, I was getting dialog error stating "Unable to start the program 'http://localhost:18980/'. An operation is not legal in the current state. Hopefully this post helps someone.

Since GDB 7.5 you can use these native Convenience Functions:

$_memeq(buf1, buf2, length)
$_regex(str, regex)
$_streq(str1, str2)
$_strlen(str)

Seems quite less problematic than having to execute a "foreign" strcmp() on the process' stack each time the breakpoint is hit. This is especially true for debugging multithreaded processes.

Note your GDB needs to be compiled with Python support, which is not an issue with current linux distros. To be sure, you can check it by running show configuration inside GDB and searching for --with-python. This little oneliner does the trick, too:

$ gdb -n -quiet -batch -ex 'show configuration' | grep 'with-python'
             --with-python=/usr (relocatable)

For your demo case, the usage would be

break <where> if $_streq(x, "hello")

or, if your breakpoint already exists and you just want to add the condition to it

condition <breakpoint number> $_streq(x, "hello")

$_streq only matches the whole string, so if you want something more cunning you should use $_regex, which supports the Python regular expression syntax.

You should use small caps "or" and "and" instead of OR and AND.

And beware also the spaces/tabs between keywords and arguments (you need at least two spaces).

Here is a code sample with your three keywords working fine:

Here is the file ts.txt:

  *** test cases ***
  mytest
    ${color} =  set variable  Red
    Run Keyword If  '${color}' == 'Red'  log to console  \nexecuted with single condition
    Run Keyword If  '${color}' == 'Red' or '${color}' == 'Blue' or '${color}' == 'Pink'  log to console  \nexecuted with multiple or

    ${color} =  set variable  Blue
    ${Size} =  set variable  Small
    ${Simple} =  set variable  Simple
    ${Design} =  set variable  Simple
    Run Keyword If  '${color}' == 'Blue' and '${Size}' == 'Small' and '${Design}' != '${Simple}'  log to console  \nexecuted with multiple and

    ${Size} =  set variable  XL
    ${Design} =  set variable  Complicated
    Run Keyword Unless  '${color}' == 'Black' or '${Size}' == 'Small' or '${Design}' == 'Simple'  log to console  \nexecuted with unless and multiple or

and here is what I get when I execute it:

$ pybot ts.txt
==============================================================================

To add to the already selected "Best Answer" (and others that are just as good like Suragch's), String.replace() is constrained by replacing characters that are sequential (thus taking CharSequence). However, String.replaceAll() is not constrained by replacing sequential characters only. You could replace non-sequential characters as well as long as your regular expression is constructed in such a way.

Also (most importantly and painfully obvious), replace() can only replace literal values; whereas replaceAll can replace 'like' sequences (not necessarily identical).

The rule is, if the function that is in the then handler returns a value, the promise resolves/rejects with that value, and if the function returns a promise, what happens is, the next then clause will be the then clause of the promise the function returned, so, in this case, the first example falls through the normal sequence of the thens and prints out values as one might expect, in the second example, the promise object that gets returned when you do Promise.resolve("bbb")'s then is the then that gets invoked when chaining(for all intents and purposes). The way it actually works is described below in more detail.

Quoting from the Promises/A+ spec:

The promise resolution procedure is an abstract operation taking as input a promise and a value, which we denote as [[Resolve]](promise, x). If x is a thenable, it attempts to make promise adopt the state of x, under the assumption that x behaves at least somewhat like a promise. Otherwise, it fulfills promise with the value x.

This treatment of thenables allows promise implementations to interoperate, as long as they expose a Promises/A+-compliant then method. It also allows Promises/A+ implementations to “assimilate” nonconformant implementations with reasonable then methods.

The key thing to notice here is this line:

if x is a promise, adopt its state [3.4]

I'm not familiar with Wordpress templates, but I'm assuming that headers are sent to the browser by WP before your template is even loaded. Because of that, the common redirection method of:

header("Location: new_url");

won't work. Unless there's a way to force sending headers through a template before WP does anything, you'll need to use some Javascript like so:

<script language="javascript" type="text/javascript">
document.location = "new_url";
</script>

Put that in the section and it'll be run when the page loads. This method won't be instant, and it also won't work for people with Javascript disabled.

I want change default directory dumpfile.

You could create a new directory and give it required privileges, for example:

SQL> CREATE DIRECTORY dmpdir AS '/opt/oracle';
Directory created.

SQL> GRANT read, write ON DIRECTORY dmpdir TO scott;
Grant succeeded.

To use the newly created directory, you could just add it as a parameter:

DIRECTORY=dmpdir

Oracle introduced a default directory from 10g R2, called DATA_PUMP_DIR, that can be used. To check the location, you could look into dba_directories:

SQL> select DIRECTORY_NAME, DIRECTORY_PATH from dba_directories where DIRECTORY_NAME = 'DATA_PUMP_DIR';

DIRECTORY_NAME       DIRECTORY_PATH
-------------------- --------------------------------------------------
DATA_PUMP_DIR        C:\app\Lalit/admin/orcl/dpdump/

HttpClient is new in .net 4.5. You should probably be using HttpWebRequest.

Based on your previous questions, I suppose you want to run JavaScript snippets from Java's WebDriver. Please correct me if I'm wrong.

The WebDriverJs is actually "just" another WebDriver language binding (you can write your tests in Java, C#, Ruby, Python, JS and possibly even more languages as of now). This one, particularly, is JavaScript, and allows you therefore to write tests in JavaScript.

If you want to run JavaScript code in Java WebDriver, do this instead:

WebDriver driver = new AnyDriverYouWant();
if (driver instanceof JavascriptExecutor) {
    ((JavascriptExecutor)driver).executeScript("yourScript();");
} else {
    throw new IllegalStateException("This driver does not support JavaScript!");
}

I like to do this, also:

WebDriver driver = new AnyDriverYouWant();
JavascriptExecutor js;
if (driver instanceof JavascriptExecutor) {
    js = (JavascriptExecutor)driver;
} // else throw...

// later on...
js.executeScript("return document.getElementById('someId');");

You can find more documentation on this here, in the documenation, or, preferably, in the JavaDocs of JavascriptExecutor.

The executeScript() takes function calls and raw JS, too. You can return a value from it and you can pass lots of complicated arguments to it, some random examples:

1. // returns the right WebElement
   // it's the same as driver.findElement(By.id("someId"))
   js.executeScript("return document.getElementById('someId');");
   

2. // draws a border around WebElement
   WebElement element = driver.findElement(By.anything("tada"));
   js.executeScript("arguments[0].style.border='3px solid red'", element);
   

3. // changes all input elements on the page to radio buttons
   js.executeScript(
           "var inputs = document.getElementsByTagName('input');" +
           "for(var i = 0; i < inputs.length; i++) { " +
           "    inputs[i].type = 'radio';" +
           "}" );
   

While this is a wild guess and may not be applicable in your specific situation, this could've saved me an hour or so.

In case you have "converted" a plain project into Java project (by editing .project file and adding appropriate tag), make sure you also have a proper specified - my project didn't get built even though Eclipse attempted to and run no builders (success!):

<buildSpec>
    <buildCommand>
        <name>org.eclipse.jdt.core.javabuilder</name>
        <arguments>
        </arguments>
    </buildCommand>
</buildSpec>

Similar issue where I was getting permissions failed. On my setup, I SSH in only. So What I did to correct the issue was

sudo MySQL
SELECT User, Host FROM mysql.user WHERE Host <> '%';
MariaDB [(none)]> SELECT User, Host FROM mysql.user WHERE Host <> '%';
+-------+-------------+
| User  | Host        |
+-------+-------------+
| root  | 169.254.0.% |
| foo   | 192.168.0.% |
| bar   | 192.168.0.% |
+-------+-------------+
4 rows in set (0.00 sec)

I need these users moved to 'localhost'. So I issued the following:

UPDATE mysql.user SET host = 'localhost' WHERE user = 'foo';
UPDATE mysql.user SET host = 'localhost' WHERE user = 'bar';

Run SELECT User, Host FROM mysql.user WHERE Host <> '%'; again and we see:

MariaDB [(none)]> SELECT User, Host FROM mysql.user WHERE Host <> '%';
+-------+-------------+
| User  | Host        |
+-------+-------------+
| root  | 169.254.0.% |
| foo   | localhost   |
| bar   | localhost   |
+-------+-------------+
4 rows in set (0.00 sec)

And then I was able to work normally again. Hope that helps someone.

Eclipse's JPA 2.0 support through Dali (which is included in "Eclipse IDE for JEE Developers") has its own metamodel generator integrated with Eclipse.

1. Select your project in the Package Explorer
2. Go to Properties -> JPA dialog
3. Select source folder from Canonical metamodel (JPA 2.0) group
4. Click Apply button to generate metamodel classes in the selected source folder

This should work on any JPA provider as the generated classes are standard.

Also see here.

The answer to the question was already posted by the @latemail in the comments above. You can use regular expressions for the second and subsequent arguments of filter like this:

dplyr::filter(df, !grepl("RTB",TrackingPixel))

Since you have not provided the original data, I will add a toy example using the mtcars data set. Imagine you are only interested in cars produced by Mazda or Toyota.

mtcars$type <- rownames(mtcars)
dplyr::filter(mtcars, grepl('Toyota|Mazda', type))

   mpg cyl  disp  hp drat    wt  qsec vs am gear carb           type
1 21.0   6 160.0 110 3.90 2.620 16.46  0  1    4    4      Mazda RX4
2 21.0   6 160.0 110 3.90 2.875 17.02  0  1    4    4  Mazda RX4 Wag
3 33.9   4  71.1  65 4.22 1.835 19.90  1  1    4    1 Toyota Corolla
4 21.5   4 120.1  97 3.70 2.465 20.01  1  0    3    1  Toyota Corona

If you would like to do it the other way round, namely excluding Toyota and Mazda cars, the filter command looks like this:

dplyr::filter(mtcars, !grepl('Toyota|Mazda', type))

@theczechsensation's solution is already half way there.

For those who like to exclude noisy log messages and keep the log to their app only this is the solution:

Add your exclusions to Log Tag like this: ^(?!(eglCodecCommon|tagToExclude))

Add your package name or prefix to Package Name: com.mycompany.

This way it is possible to filter for as many strings you like and keep the log to your package.

This is my best solution. I used this many times.

class DictLikeClass:
    ...
    def __getitem__(self, key):
        return getattr(self, key)

    def __setitem__(self, key, value):
        setattr(self, key, value)
    ...

You can use like:

>>> d = DictLikeClass()
>>> d["key"] = "value"
>>> print(d["key"])

If you try to declare a variable, or a property in your header file, which you didn't import yet, your gonna get an error saying that the compiler doesn't know this class.

Your first thought is probably #import it.
This may cause problems in some cases.

For example if you implement a bunch of C-methods in the header file, or structs, or something similar, because they shouldn't be imported multiple times.

Therefore you can tell the compiler with @class:

I know you don't know that class, but it exists. It's going to be imported or implemented elsewhere

It basically tells the compiler to shut up and compile, even though it's not sure if this class is ever going to be implemented.

You will usually use #import in the .m and @class in the .h files.

In order for new T to compile, T must be a complete type. In your case, when you say new tile_tree_apple inside the definition of tile_tree::tick, tile_tree_apple is incomplete (it has been forward declared, but its definition is later in your file). Try moving the inline definitions of your functions to a separate source file, or at least move them after the class definitions.

Something like:

class A
{
    void f1();
    void f2();
};
class B
{
   void f3();
   void f4();
};

inline void A::f1() {...}
inline void A::f2() {...}
inline void B::f3() {...}
inline void B::f4() {...}

When you write your code this way, all references to A and B in these methods are guaranteed to refer to complete types, since there are no more forward references!

There is a small (HUGE) understatement here. If you want to copy a HashMap with nested structures, HashMap.putAll() will copy by reference, because it doesn't know how to exactly copy your object. For example:

import java.util.*;
class Playground {
    public static void main(String[ ] args) {
        Map<Integer, Map<Integer,List<Float>>> dataA = new HashMap<>();
        Map<Integer, Map<Integer,List<Float>>> dataB = new HashMap<>();

        dataA.put(1, new HashMap<>());
        dataB.putAll(dataA);

        assert(dataB.get(1).size() == 0);

        dataA.get(1).put(2, new ArrayList<>());

        if (dataB.get(1).size() == 1) { // true
            System.out.println(
                "Sorry object reference was copied - not the values");
        }
    }
}

So basically you will need to copy the fields yourself like here

List <Float> aX = new ArrayList<>(accelerometerReadingsX);
List <Float> aY = new ArrayList<>(accelerometerReadingsY);

List <Float> gX = new ArrayList<>(gyroscopeReadingsX);
List <Float> gY = new ArrayList<>(gyroscopeReadingsY);

Map<Integer, Map<Integer, Float>> readings = new HashMap<>();

Map<Integer,List<Float>> accelerometerReadings = new HashMap<>();
accelerometerReadings.put(X_axis, aX);
accelerometerReadings.put(Y_axis, aY);
readings.put(Sensor.TYPE_ACCELEROMETER, accelerometerReadings);

Map<Integer,List<Float>> gyroscopeReadings = new HashMap<>();
gyroscopeReadings.put(X_axis, gX);
gyroscopeReadings.put(Y_axis, gY);
readings.put(Sensor.TYPE_GYROSCOPE, gyroscopeReadings);

A convenient way would be boost's string algorithms library.

#include <boost/algorithm/string/classification.hpp> // Include boost::for is_any_of
#include <boost/algorithm/string/split.hpp> // Include for boost::split
// ...

std::vector<std::string> words;
std::string s;
boost::split(words, s, boost::is_any_of(", "), boost::token_compress_on);

to prevent words in edittext. create a class that u could use anytime.

public class Wordfilter implements InputFilter
{
    @Override
    public CharSequence filter(CharSequence source, int start, int end,Spanned dest, int dstart, int dend) {
        // TODO Auto-generated method stub
        boolean append = false;
        String text = source.toString().substring(start, end);
        StringBuilder str = new StringBuilder(dest.toString());
        if(dstart == str.length())
        {
            append = true;
            str.append(text);
        }
        else
            str.replace(dstart, dend, text);
        if(str.toString().contains("aaaaaaaaaaaa/*the word here*/aaaaaaaa"))
        {
            if(append==true)
                return "";
            else
                return dest.subSequence(dstart, dend);
        }
        return null;
    }
}

I have the same issue. The java.net.SocketTimeoutException: Read timed out error happens on Tomcat under Mac 11.1, but it works perfectly in Mac 10.13. Same Tomcat folder, same WAR file. Have tried setting timeout values higher, but nothing I do works. If I run the same SpringBoot code in a regular Java application (outside Tomcat 9.0.41 (tried other versions too), then it works also.

Mac 11.1 appears to be interfering with Tomcat.

As another test, if I copy the WAR file to an AWS EC2 instance, it works fine there too.

Spent several days trying to figure this out, but cannot resolve.

Suggestions very welcome! :)

The answer probably depends on what format your date is in, but here is an example using the Date class:

dt <- as.Date("2010/02/10")
new.dt <- dt - as.difftime(2, unit="days")

You can even play with different units like weeks.

The problem is that the body of the page isn't actually visible. The DIVs under have width of 100% and have background colors themselves that override the body CSS.

To Fix the no-man's land, this might work. It's not elegant, but works.

#doc3 {

Just Try this command on your terminal

php artisan make:model Todo -mcr

suppose your JAR file is in C:\Documents and Settings\mmeher\Desktop\jar and the JAR file name is xx.jar, then write the below two commands in command prompt:

2> jar xf xx.jar

If you patch /Developer/Platforms/iPhoneOS.platform/Info.plist and then try to debug a application running on the device using a real development provisionen profile from Apple it will probably not work. Symptoms are weird error messages from com.apple.debugserver and that you can use any bundle identifier without getting a error when building in Xcode. The solution is to restore Info.plist.

The dataframe.sort() method is - so my understanding - deprecated in pandas > 0.18. In order to solve your problem you should use dataframe.sort_values() instead:

f.sort_values(by=["c1","c2"], ascending=[False, True])

The output looks like this:

    c1  c2
    3   10
    2   15
    2   30
    2   100
    1   20

Mongodb and Mongoose are two completely different things!

Mongodb is the database itself, while Mongoose is an object modeling tool for Mongodb

EDIT: As pointed out MongoDB is the npm package, thanks!

It's easy to get this error in a multi-module project. If, for example, you made changes to modules A, B, and C, but then you try to compile just module B, you are susceptible to this error. Say module B has a dependency on module A. Since only module B was compiled, the class files from module A are now out of date and possibly invalid.

Compiling all the modules (or modules in the proper hierarchical dependency order) resolves this error, if this is the nature of your problem.

Try this instead:

var responseObject = proxy.CallService(new RequestObject
{
    Data = "misc. data",
    Guid = new Guid.NewGuid()
});

This will generate a 'real' Guid value. When you new a reference type, it will give you the default value (which in this case, is all zeroes for a Guid).

When you create a new Guid, it will initialize it to all zeroes, which is the default value for Guid. It's basically the same as creating a "new" int (which is a value type but you can do this anyways):

Guid g1;                    // g1 is 00000000-0000-0000-0000-000000000000
Guid g2 = new Guid();       // g2 is 00000000-0000-0000-0000-000000000000
Guid g3 = default(Guid);    // g3 is 00000000-0000-0000-0000-000000000000
Guid g4 = Guid.NewGuid();   // g4 is not all zeroes

Compare this to doing the same thing with an int:

int i1;                     // i1 is 0
int i2 = new int();         // i2 is 0
int i3 = default(int);      // i3 is 0

For those of you who, like me, come to this issue from Django, you should know that the docs provide a solution: https://docs.djangoproject.com/en/1.10/ref/models/fields/#foreignkey

"...To refer to models defined in another application, you can explicitly specify a model with the full application label. For example, if the Manufacturer model above is defined in another application called production, you’d need to use:

class Car(models.Model):
    manufacturer = models.ForeignKey(
        'production.Manufacturer',
        on_delete=models.CASCADE,
)

At login, most shells execute a login script, which you can use to execute your custom script. The login script the shell executes depends, of course, upon the shell:

• bash: .bash_profile, .bash_login, .profile (for backwards compabitibility)
• sh: .profile
• tcsh and csh: .login
• zsh: .zshrc

You can probably find out what shell you're using by doing

echo $SHELL

from the prompt.

For a slightly wider definition of 'login', it's useful to know that on most distros when X is launched, your .xsessionrc will be executed when your X session is started.

To dynamically set the "selected" value of a Select2 component:

$('#inputID').select2('data', {id: 100, a_key: 'Lorem Ipsum'});

Where the second parameter is an object with expected values.

UPDATE:

This does work, just wanted to note that in the new select2, "a_key" is "text" in a standard select2 object. so: {id: 100, text: 'Lorem Ipsum'}

Example:

$('#all_contacts').select2('data', {id: '123', text: 'res_data.primary_email'});

Hmmm... Keep in mind that Class may or may not implement equals() -- that is not required by the spec. For instance, HP Fortify will flag myClass.equals(myOtherClass).

Clear backstack without loops

String name = getSupportFragmentManager().getBackStackEntryAt(0).getName();
getSupportFragmentManager().popBackStack(name, FragmentManager.POP_BACK_STACK_INCLUSIVE);

Where name is the addToBackStack() parameter

getSupportFragmentManager().beginTransaction().
                .replace(R.id.container, fragments.get(titleCode))
                .addToBackStack(name)

In my case it was happening because I had not typed a variable.

So I created the Search interface

export interface Search {
  term: string;
  ...
}

I changed that

searchList = [];

for that and it worked

searchList: Search[];

Try:

EditText edt = (EditText) findViewById(R.id.YourEditText);
RelativeLayout.LayoutParams lp =
    new RelativeLayout.LayoutParams
    (
        LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT
    );
lp.setMargins(25, 0, 0, 0); // move 25 px to right (increase left margin)
edt.setLayoutParams(lp); // lp.setMargins(left, top, right, bottom);

Since there is no native way to do this ,Here is less intrusive solution i found (dont add any 'old' prototype methods):

var ListenerTracker=new function(){
    var is_active=false;
    // listener tracking datas
    var _elements_  =[];
    var _listeners_ =[];
    this.init=function(){
        if(!is_active){//avoid duplicate call
            intercep_events_listeners();
        }
        is_active=true;
    };
    // register individual element an returns its corresponding listeners
    var register_element=function(element){
        if(_elements_.indexOf(element)==-1){
            // NB : split by useCapture to make listener easier to find when removing
            var elt_listeners=[{/*useCapture=false*/},{/*useCapture=true*/}];
            _elements_.push(element);
            _listeners_.push(elt_listeners);
        }
        return _listeners_[_elements_.indexOf(element)];
    };
    var intercep_events_listeners = function(){
        // backup overrided methods
        var _super_={
            "addEventListener"      : HTMLElement.prototype.addEventListener,
            "removeEventListener"   : HTMLElement.prototype.removeEventListener
        };

        Element.prototype["addEventListener"]=function(type, listener, useCapture){
            var listeners=register_element(this);
            // add event before to avoid registering if an error is thrown
            _super_["addEventListener"].apply(this,arguments);
            // adapt to 'elt_listeners' index
            useCapture=useCapture?1:0;

            if(!listeners[useCapture][type])listeners[useCapture][type]=[];
            listeners[useCapture][type].push(listener);
        };
        Element.prototype["removeEventListener"]=function(type, listener, useCapture){
            var listeners=register_element(this);

            var lid = listeners[useCapture][type].indexOf(listener);
            if(lid>-1)listeners[useCapture][type].splice(lid,1);
        };
        Element.prototype["getEventListeners"]=function(type){
            var listeners=register_element(this);
            // convert to listener datas list
            var result=[];
            for(var useCapture=0,list;list=listeners[useCapture];useCapture++){

There are multiple nuget packages read in the following order:

1. First the NuGetDefaults.Config file. You will find this in %ProgramFiles(x86)%\NuGet\Config.
2. The computer-level file.
3. The user-level file. You will find this in %APPDATA%\NuGet\nuget.config.
4. Any file named nuget.config beginning from the root of your drive up to the directory where nuget.exe is called.
5. The config file you specify in the -configfile option when calling nuget.exe

What about using this syntax (take a look in this plunker). I just discovered this and it's pretty awesome.

ng-repeat="(key,value) in data"

Example:

<div ng-repeat="(indexX,object) in data">
    <div ng-repeat="(indexY,value) in object">
       {{indexX}} - {{indexY}} - {{value}}
    </div>
</div>

With this syntax you can give your own name to $index and differentiate the two indexes.

This will ensure you get a two-digit day and month.

function formattedDate(d = new Date) {
  let month = String(d.getMonth() + 1);
  let day = String(d.getDate());
  const year = String(d.getFullYear());

  if (month.length < 2) month = '0' + month;
  if (day.length < 2) day = '0' + day;

  return `${day}/${month}/${year}`;
}

Or terser:

function formattedDate(d = new Date) {
  return [d.getDate(), d.getMonth()+1, d.getFullYear()]
      .map(n => n < 10 ? `0${n}` : `${n}`).join('/');
}

String onevalue;   
if(request.getParameterMap().containsKey("one")!=false) 
{
onevalue=request.getParameter("one").toString();
}

To add to Mosh Feu answer, if the tabs where created on the fly like in my case, you would use the following code

$(document).on('shown.bs.tab', 'a[data-toggle="tab"]', function (e) {
    var tab = $(e.target);
    var contentId = tab.attr("href");

    //This check if the tab is active
    if (tab.parent().hasClass('active')) {
         console.log('the tab with the content id ' + contentId + ' is visible');
    } else {
         console.log('the tab with the content id ' + contentId + ' is NOT visible');
    }

});

I hope this helps someone

  File "C:\pythonwork\readthefile080410.py", line 120, in medications_minimum3

row[11] is unhashable. It's a list. That is precisely (and only) what the error message means. You might not like it, but that is the error message.

Do this

counter[tuple(row[11])]+=1

Also, simplify.

I found a way to display activity Indicator with minimum code:

first of all import your UI Kit

import UIKit;

Then you have to initiate activity indicator

let activityIndicator:UIActivityIndicatorView = UIActivityIndicatorView();

Then just copy paste this functions below which are self explainatory and call them whereever you need them:

func startLoading(){
    activityIndicator.center = self.view.center;
    activityIndicator.hidesWhenStopped = true;
    activityIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyle.gray;
    view.addSubview(activityIndicator);

    activityIndicator.startAnimating();
    UIApplication.shared.beginIgnoringInteractionEvents();

}

func stopLoading(){ 

    activityIndicator.stopAnimating();
    UIApplication.shared.endIgnoringInteractionEvents();

}

Quick answer: change int testlib() to int testlib(void) to specify that the function takes no arguments.

A prototype is by definition a function declaration that specifies the type(s) of the function's argument(s).

A non-prototype function declaration like

int foo();

is an old-style declaration that does not specify the number or types of arguments. (Prior to the 1989 ANSI C standard, this was the only kind of function declaration available in the language.) You can call such a function with any arbitrary number of arguments, and the compiler isn't required to complain -- but if the call is inconsistent with the definition, your program has undefined behavior.

For a function that takes one or more arguments, you can specify the type of each argument in the declaration:

int bar(int x, double y);

Functions with no arguments are a special case. Logically, empty parentheses would have been a good way to specify that an argument but that syntax was already in use for old-style function declarations, so the ANSI C committee invented a new syntax using the void keyword:

int foo(void); /* foo takes no arguments */

A function definition (which includes code for what the function actually does) also provides a declaration. In your case, you have something similar to:

int testlib()
{
    /* code that implements testlib */
}

This provides a non-prototype declaration for testlib. As a definition, this tells the compiler that testlib has no parameters, but as a declaration, it only tells the compiler that testlib takes some unspecified but fixed number and type(s) of arguments.

If you change () to (void) the declaration becomes a prototype.

The advantage of a prototype is that if you accidentally call testlib with one or more arguments, the compiler will diagnose the error.

(C++ has slightly different rules. C++ doesn't have old-style function declarations, and empty parentheses specifically mean that a function takes no arguments. C++ supports the (void) syntax for consistency with C. But unless you specifically need your code to compile both as C and as C++, you should probably use the () in C++ and the (void) syntax in C.)

By adding a few more headers I was able to get the data:

import urllib2,cookielib

site= "http://www.nseindia.com/live_market/dynaContent/live_watch/get_quote/getHistoricalData.jsp?symbol=JPASSOCIAT&fromDate=1-JAN-2012&toDate=1-AUG-2012&datePeriod=unselected&hiddDwnld=true"
hdr = {'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.64 Safari/537.11',
       'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
       'Accept-Charset': 'ISO-8859-1,utf-8;q=0.7,*;q=0.3',
       'Accept-Encoding': 'none',
       'Accept-Language': 'en-US,en;q=0.8',
       'Connection': 'keep-alive'}

req = urllib2.Request(site, headers=hdr)

try:
    page = urllib2.urlopen(req)
except urllib2.HTTPError, e:
    print e.fp.read()

content = page.read()
print content

Actually, it works with just this one additional header:

'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',

Going off of tbradley22's answer, but using .map instead:

var a = ["car", "bike", "scooter"];
a.map(function(entry) {
    var singleObj = {};
    singleObj['type'] = 'vehicle';
    singleObj['value'] = entry;
    return singleObj;
});

The ifelse function would be a quick and easy way to do this.

This one always keeps the right frame:

public extension UIView {

    @discardableResult
    public func addBlur(style: UIBlurEffect.Style = .extraLight) -> UIVisualEffectView {
        let blurEffect = UIBlurEffect(style: style)
        let blurBackground = UIVisualEffectView(effect: blurEffect)
        addSubview(blurBackground)
        blurBackground.translatesAutoresizingMaskIntoConstraints = false
        blurBackground.bottomAnchor.constraint(equalTo: bottomAnchor).isActive = true
        blurBackground.topAnchor.constraint(equalTo: topAnchor).isActive = true
        blurBackground.leadingAnchor.constraint(equalTo: leadingAnchor).isActive = true
        blurBackground.trailingAnchor.constraint(equalTo: trailingAnchor).isActive = true
        return blurBackground
    }
}

I got the following to work:

$Command1="C:\\ProgramData\Amazon\Tools\ebsnvme-id.exe"
$result = & invoke-Expression $Command1 | Out-String

$result gives you the needful

We don't need to depend on the Google Collections external library. You can simply implement the following Map:

Map<String, ArrayList<String>> hashMap = new HashMap<String, ArrayList>();

public static void main(String... arg) {
   // Add data with duplicate keys
   addValues("A", "a1");
   addValues("A", "a2");
   addValues("B", "b");
   // View data.
   Iterator it = hashMap.keySet().iterator();
   ArrayList tempList = null;

   while (it.hasNext()) {
      String key = it.next().toString();             
      tempList = hashMap.get(key);
      if (tempList != null) {
         for (String value: tempList) {
            System.out.println("Key : "+key+ " , Value : "+value);
         }
      }
   }
}

private void addValues(String key, String value) {
   ArrayList tempList = null;
   if (hashMap.containsKey(key)) {
      tempList = hashMap.get(key);
      if(tempList == null)
         tempList = new ArrayList();
      tempList.add(value);  
   } else {
      tempList = new ArrayList();
      tempList.add(value);               
   }
   hashMap.put(key,tempList);
}

Please make sure to fine tune the code.

I agree with @kent that this is well suited for grep -o. If you need to extract a group within a pattern, you can do it with a 2nd grep.

# To extract \1 from /xx([0-9]+)yy/
$ echo "aa678bb xx123yy xx4yy aa42 aa9bb" | grep -Eo 'xx[0-9]+yy' | grep -Eo '[0-9]+'
123
4

# To extract \1 from /a([0-9]+)b/
$ echo "aa678bb xx123yy xx4yy aa42 aa9bb" | grep -Eo 'a[0-9]+b' | grep -Eo '[0-9]+'
678
9

I generally cringe when I see 2 calls to grep/sed/awk piped together, but it's not always wrong. While we should exercise our skills of doing things efficiently, "A foolish consistency is the hobgoblin of little minds", and "Real artists ship".

What have you tried, what was the problem?

Creating DataColumns and add values to a DataTable is straight forward:

Dim dt = New DataTable()
Dim dcID = New DataColumn("ID", GetType(Int32))
Dim dcName = New DataColumn("Name", GetType(String))
dt.Columns.Add(dcID)
dt.Columns.Add(dcName)
For i = 1 To 1000
    dt.Rows.Add(i, "Row #" & i)
Next

Edit:

If you want to read a xml file and load a DataTable from it, you can use DataTable.ReadXml.

If I understand well, you want to Join ScheduleRequest with User and apply the in clause to the userName property of the entity User.

I'd need to work a bit on this schema. But you can try with this trick, that is much more readable than the code you posted, and avoids the Join part (because it handles the Join logic outside the Criteria Query).

List<String> myList = new ArrayList<String> ();
for (User u : usersList) {
    myList.add(u.getUsername());
}
Expression<String> exp = scheduleRequest.get("createdBy");
Predicate predicate = exp.in(myList);
criteria.where(predicate);

In order to write more type-safe code you could also use Metamodel by replacing this line:

Expression<String> exp = scheduleRequest.get("createdBy");

with this:

Expression<String> exp = scheduleRequest.get(ScheduleRequest_.createdBy);

If it works, then you may try to add the Join logic into the Criteria Query. But right now I can't test it, so I prefer to see if somebody else wants to try.

Not a perfect answer though may be code snippets might help.

public <T> List<T> findListWhereInCondition(Class<T> clazz,
            String conditionColumnName, Serializable... conditionColumnValues) {
        QueryBuilder<T> queryBuilder = new QueryBuilder<T>(clazz);
        addWhereInClause(queryBuilder, conditionColumnName,
                conditionColumnValues);
        queryBuilder.select();
        return queryBuilder.getResultList();

    }


private <T> void addWhereInClause(QueryBuilder<T> queryBuilder,
            String conditionColumnName, Serializable... conditionColumnValues) {

        Path<Object> path = queryBuilder.root.get(conditionColumnName);
        In<Object> in = queryBuilder.criteriaBuilder.in(path);
        for (Serializable conditionColumnValue : conditionColumnValues) {
            in.value(conditionColumnValue);
        }
        queryBuilder.criteriaQuery.where(in);

    }

I was facing the same issue. In our application the instance of FireFox was created by passing the DesiredCapabilities as follows

driver = new FirefoxDriver(capabilities);

Based on the suggestions by others, I did my changes as

FirefoxProfile firefoxProfile = new FirefoxProfile();     
firefoxProfile.setPreference("browser.helperApps.neverAsk.saveToDisk",
    "application/octet-stream");
driver = new FirefoxDrvier(firefoxProfile);

This served the purpose but unfortunately my other automation tests started failing. And the reason was, I have removed the capabilities which were being passed earlier.

Some more browsing on net and found an alternate way. We can set the profile itself in the desired Capabilities.

So the new working code looks like

DesiredCapabilities capabilities = DesiredCapabilities.firefox();

// add more capabilities as per your need.
FirefoxProfile firefoxProfile = new FirefoxProfile();        
firefoxProfile.setPreference("browser.helperApps.neverAsk.saveToDisk",
    "application/octet-stream");

// set the firefoxprofile as a capability
capabilities.setCapability(FirefoxDriver.PROFILE, firefoxProfile);
driver = new FirefoxDriver(capabilities);

As of today, there is an official Android-hosted copy of Volley available on JCenter:

compile 'com.android.volley:volley:1.0.0'

This was compiled from the AOSP volley source code.

It's also possible to to do this without the wrapper - div#main. You can center the #page-wrap using the margin: 0 auto; method and then use the left:-n; method to position the #sidebar and adding the width of #page-wrap.

body { background: black; }
#sidebar    {
    position: absolute;
    left: 50%;
    width: 200px;
    height: 400px;
    background: red;
    margin-left: -230px;
    }

#page-wrap  {
    width: 60px;
    background: #fff;
    height: 400px;
    margin: 0 auto;
    }

However, the sidebar would disappear beyond the browser viewport if the window was smaller than the content.

Nick's second answer is best though, because it's also more maintainable as you don't have to adjust #sidebar if you want to resize #page-wrap.

Plug in your network cable into a switch which has no other connection/cables. That should work imho.

Go to your client machine and type in:

nslookup server.company.com

substituting the real host name of your server for server.company.com, of course.

That should tell you which DNS server your client is using (if any) and what it thinks the problem is with the name.

To force an application to use an IP address, generally you just configure it to use the IP address instead of a host name. If the host name is hard-coded, or the application insists on using a host name in preference to an IP address (as one of your other comments seems to indicate), then you're probably out of luck there.

However, you can change the way that most machine resolve the host names, such as with /etc/resolv.conf and /etc/hosts on UNIXy systems and a local hosts file on Windows-y systems.

I dont see anyone mentioning the ClassInitialize attribute method. The attributes are pretty straight forward.

Create methods that are marked with either the [ClassInitialize()] or [TestInitialize()] attribute to prepare aspects of the environment in which your unit test will run. The purpose of this is to establish a known state for running your unit test. For example, you may use the [ClassInitialize()] or the [TestInitialize()] method to copy, alter, or create certain data files that your test will use.

Create methods that are marked with either the [ClassCleanup()] or [TestCleanUp{}] attribute to return the environment to a known state after a test has run. This might mean the deletion of files in folders or the return of a database to a known state. An example of this is to reset an inventory database to an initial state after testing a method that is used in an order-entry application.

• [ClassInitialize()] Use ClassInitialize to run code before you run the first test in the class.

• [ClassCleanUp()] Use ClassCleanup to run code after all tests in a class have run.

• [TestInitialize()] Use TestInitialize to run code before you run each test.

• [TestCleanUp()] Use TestCleanup to run code after each test has run.

I would strongly recommend using a library like PHPMailer to send emails.
It's easier and handles most of the issues automatically for you.

Regarding displaying embedded (inline) images, here's what's on their documentation:

Inline Attachments

There is an additional way to add an attachment. If you want to make a HTML e-mail with images incorporated into the desk, it's necessary to attach the image and then link the tag to it. For example, if you add an image as inline attachment with the CID my-photo, you would access it within the HTML e-mail with <img src="cid:my-photo" alt="my-photo" />.

In detail, here is the function to add an inline attachment:

$mail->AddEmbeddedImage(filename, cid, name);
//By using this function with this example's value above, results in this code:
$mail->AddEmbeddedImage('my-photo.jpg', 'my-photo', 'my-photo.jpg ');

To give you a more complete example of how it would work:

<?php
require_once('../class.phpmailer.php');
$mail = new PHPMailer(true); // the true param means it will throw exceptions on     errors, which we need to catch

$mail->IsSMTP(); // telling the class to use SMTP

try {
  $mail->Host       = "mail.yourdomain.com"; // SMTP server
  $mail->Port       = 25;                    // set the SMTP port
  $mail->SetFrom('[email protected]', 'First Last');
  $mail->AddAddress('[email protected]', 'John Doe');
  $mail->Subject = 'PHPMailer Test';

  $mail->AddEmbeddedImage("rocks.png", "my-attach", "rocks.png");
  $mail->Body = 'Your <b>HTML</b> with an embedded Image: <img src="cid:my-attach"> Here is an image!';

  $mail->AddAttachment('something.zip'); // this is a regular attachment (Not inline)
  $mail->Send();
  echo "Message Sent OK<p></p>\n";
} catch (phpmailerException $e) {
  echo $e->errorMessage(); //Pretty error messages from PHPMailer
} catch (Exception $e) {
  echo $e->getMessage(); //Boring error messages from anything else!
}
?>

Edit:

Regarding your comment, you asked how to send HTML email with embedded images, so I gave you an example of how to do that.
The library I told you about can send emails using a lot of methods other than SMTP.
Take a look at the PHPMailer Example page for other examples.

One way or the other, if you don't want to send the email in the ways supported by the library, you can (should) still use the library to build the message, then you send it the way you want.

For example:

You can replace the line that send the email:

$mail->Send();

With this:

$mime_message = $mail->CreateBody(); //Retrieve the message content
echo $mime_message; // Echo it to the screen or send it using whatever method you want

Hope that helps. Let me know if you run into trouble using it.

From what I've gathered this means the mysql service (mysqld) isn't running.

• First make sure it is installed as a windows service : Run

"C:\Program Files\MySQL\MySQL Server 5.5\bin\mysqld" --install

from the command line.

• Next, start it up :

services.msc > MySQL > start

If it fails to restart, then you can follow these steps :

• open the command line as an administrator : cmd.exe > open as administrator
• run "C:\Program Files\MySQL\MySQL Server 5.7\bin\mysqld" --verbose

it should fail and put the error log in a directory named data under C:\Program Files\MySQL\MysSQL Server 5.7\ . If it fails to create data for some reason, do it manually under that directory and try again. If you can figure out what's missing from what's in that log, then good, you're done.

If you've still got no luck, this is how I did it :

• goto C:\ProgramData\MySQL and copy the file named my.ini to C:\Windows\

• try to start the service again from the command line : "C:\Program Files\MySQL\MySQL Server 5.7\bin\mysqld" --verbose

If it doesn't display any error, than the service startup was successfull. If it's still not working, than delete that my.ini you just copied from C:\Windows and start the service from the command line once again.

it should work now

According to the Java Language Specification (specifically §10.7 Array Members) it is a field:

• The public final field length, which contains the number of components of the array (length may be positive or zero).

Internally the value is probably stored somewhere in the object header, but that is an implementation detail and depends on the concrete JVM implementation.

The HotSpot VM (the one in the popular Oracle (formerly Sun) JRE/JDK) stores the size in the object-header:

[...] arrays have a third header field, for the array size.

call this method and pass your set

func getArrayFromSet(set:NSSet)-> NSArray {

return set.map ({ String($0) })
}

Like This :

var letters:Set = Set<String>(arrayLiteral: "test","test") // your set
print(self.getArrayFromSet(letters))

You can use the bootstrap grid system. as Yoann said

datepicker doesnot have a maxDate as an option.I used this endDate option.It worked well.

> $('.demo-calendar-default').datepicker({

I was facing the same issue. I had installed nodemon as a dev-dependency and when I tried to start the server it gave the message that

nodemon is not recognized as internal or external command, operable program or batch file

Then I installed it globally and tried to start the server and it worked!

npm install -g nodemon

Well, the "-a" mail and mailx in Centos7 is "attach file" not "append header." My shortest path to a solution on Centos7 from here: stackexchange.com

Basically:

yum install mutt
mutt -e 'set content_type=text/html' -s 'My subject' [email protected] < msg.html

Put the text in an inline element, such as a <span>.

<h1><span>The Last Will and Testament of Eric Jones</span></h1>

And then apply the background color on the inline element.

h1 {
    text-align: center; 
}
h1 span { 
    background-color: green; 
}

An inline element is as big as its contents is, so that should do it for you.

C++ forest

Like this :

var id = $('div.foo').attr('id');
$('div.foo').attr('id', id + ' id_adding');

1. get actual ID
2. put actuel ID and add the new one

I've the same problem, and by the "trial and error" method I have the steps to install the guest additions on a MacOS guest:

1. insert the guest additions cd
2. open the cd on file manager
3. double click on VBoxDarwinAdditions.pkg
4. the installer opens, then click contine
5. next screen to set location of installed files, only press install
6. your password can be asked a couple of time while installing, write it and continue
7. this is the tricky part, on my installation, macos show an message about the driver created by oracle won't be installed because a security issue, it has the option to enable it, so click on the button to open security screen and click on the allow button next to the oracle software listed at bottom of the security settings window, it will ask your password again. Meanwhile the pkg installer continued as if it has permissions and will say "install finished", but I don't believe it so, once I unlocked the oracle drivers installations I repeat the whole process from step 3, and in the second round all installs without asking more than the first password to install.

And it is done!

I actually just overwrite anything I want to change in the site.css, you should load the site.css after bootstrap so it will overwrite the classes. What I have done now is just made my own classes with my own little bootstrap theme. Little things like this

.navbar-nav li a{
    color: #fff;
    font-size: 15px;
    margin-top: 9px;
}
.navbar-nav li a:hover{

    background-color: #18678E;
    height: 61px;
}

I also changed the likes of the validations errors the same way.

As per select2 documentation: Click Here

If you wants to disable select2 then use this approach:

$(".js-example-disabled").prop("disabled", true);

If you wants to enable a disabled select2 box use this approach:

$(".js-example-disabled").prop("disabled", false);

It is a bit of hack but will do the task.

Function equalsIgnoreCase(str1 As String, str2 As String) As Boolean
    equalsIgnoreCase = LCase(str1) = LCase(str2)

map HTTP request header Content-Type, handle request body.

• @RequestParam ? application/x-www-form-urlencoded,

• @RequestBody ? application/json,

• @RequestPart ? multipart/form-data,

• RequestParam (Spring Framework 5.1.9.RELEASE API)

  map to query parameters, form data, and parts in multipart requests.

  RequestParam is likely to be used with name-value form fields

• RequestBody (Spring Framework 5.1.9.RELEASE API)

  bound to the body of the web request. The body of the request is passed through an HttpMessageConverter to resolve the method argument depending on the content type of the request. (e.g. JSON, XML)

• RequestPart (Spring Framework 5.1.9.RELEASE API)

  used to associate the part of a "multipart/form-data" request

  RequestPart is likely to be used with parts containing more complex content

• HttpMessageConverter (Spring Framework 5.1.9.RELEASE API)

  a converter that can convert from and to HTTP requests and responses.

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

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

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

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

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

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

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

simple solution utilizing feature of swift language that array is value type.

   for chr in chrs {
       var arr = arr
       if !arr.contains(chr) {
           arr.append(chr)
           permutation(chrs: chrs, arr: arr, result: &result)
       }
   }
}

func test() {
   var result = [[String]]()
   let chrs = ["a", "b", "c", "d"]
   permutation(chrs: chrs, arr: [], result: &result)
}

Change android:stretchColumns value to *.

Value 0 means stretch the first column. Value 1 means stretch the second column and so on.

Value * means stretch all the columns.

You need to specify data, index and columns to DataFrame constructor, as in:

>>> pd.DataFrame(data=data[1:,1:],    # values
...              index=data[1:,0],    # 1st column as index
...              columns=data[0,1:])  # 1st row as the column names

edit: as in the @joris comment, you may need to change above to np.int_(data[1:,1:]) to have correct data type.

If you want to cancel pending requests on stateChangeStart with ui-router, you can use something like this:

// in service

                var deferred = $q.defer();
                var scope = this;
                $http.get(URL, {timeout : deferred.promise, cancel : deferred}).success(function(data){
                    //do something
                    deferred.resolve(dataUsage);
                }).error(function(){
                    deferred.reject();
                });
                return deferred.promise;

// in UIrouter config

$rootScope.$on('$stateChangeStart', function (event, toState, toParams, fromState, fromParams) {
    //To cancel pending request when change state
       angular.forEach($http.pendingRequests, function(request) {
          if (request.cancel && request.timeout) {
             request.cancel.resolve();
          }
       });

main.cpp doesn't have to know what is in class.cpp. It just has to know the declarations of the functions/classes that it goes to use, and these declarations are in class.h.

The linker links between the places where the functions/classes declared in class.h are used and their implementations in class.cpp

This is what I've fund out. Maybe it will help to someone:

So here we go:

If You use LINQ with EF looking for some exact elements contained in the list like this:

await context.MyObject1.Include("MyObject2").Where(t => IdList.Contains(t.MyObjectId)).ToListAsync();

everything is going fine until IdList contains more than one Id.

The “timeout” problem comes out if the list contains just one Id. To resolve the issue use if condition to check number of ids in IdList.

Example:

if (IdList.Count == 1)
{
    result = await entities. MyObject1.Include("MyObject2").Where(t => IdList.FirstOrDefault()==t. MyObjectId).ToListAsync();
}
else
{
    result = await entities. MyObject1.Include("MyObject2").Where(t => IdList.Contains(t. MyObjectId)).ToListAsync();
}

Simply try to use Sql Profiler and check the Select statement generated by Entity frameeork. …

Cacerts are details of trusted signing authorities who can issue certs. This what most of the browsers have due to which certs determined to be authentic. Keystone has your service related certs to authenticate clients.

You need to write code in the OnLocationChanged method, because this method is called when the location has changed. I.e. you need to save the new location to return it if getLocation is called.

If you don't use the onLocationChanged it always will be the old location.

In case you want to run a PowerShell script with Windows Task Scheduler, please follow the steps below:

A method is a function that takes a class instance as its first parameter. Methods are members of classes.

class C:
    def method(self, possibly, other, arguments):
        pass # do something here

As you wanted to know what it specifically means in Python, one can distinguish between bound and unbound methods. In Python, all functions (and as such also methods) are objects which can be passed around and "played with". So the difference between unbound and bound methods is:

1) Bound methods

# Create an instance of C and call method()
instance = C()

print instance.method # prints '<bound method C.method of <__main__.C instance at 0x00FC50F8>>'
instance.method(1, 2, 3) # normal method call

f = instance.method
f(1, 2, 3) # method call without using the variable 'instance' explicitly

Bound methods are methods that belong to instances of a class. In this example, instance.method is bound to the instance called instance. Everytime that bound method is called, the instance is passed as first parameter automagically - which is called self by convention.

2) Unbound methods

print C.method # prints '<unbound method C.method>'
instance = C()
C.method(instance, 1, 2, 3) # this call is the same as...
f = C.method
f(instance, 1, 2, 3) # ..this one...

instance.method(1, 2, 3) # and the same as calling the bound method as you would usually do

When you access C.method (the method inside a class instead of inside an instance), you get an unbound method. If you want to call it, you have to pass the instance as first parameter because the method is not bound to any instance.

Knowing that difference, you can make use of functions/methods as objects, like passing methods around. As an example use case, imagine an API that lets you define a callback function, but you want to provide a method as callback function. No problem, just pass self.myCallbackMethod as the callback and it will automatically be called with the instance as first argument. This wouldn't be possible in static languages like C++ (or only with trickery).

Hope you got the point ;) I think that is all you should know about method basics. You could also read more about the classmethod and staticmethod decorators, but that's another topic.

I too liked Jordan's answer and implemented it myself. I only needed to abbreviations so in case someone else needs the same:

You can read the post request parameter with jQuery-PostCapture(@ssut/jQuery-PostCapture).

PostCapture plugin is consisted of some tricks.

When you are click the submit button, the onsubmit event will be dispatched.

At the time, PostCapture will be serialize form data and save to html5 localStorage(if available) or cookie storage.

Solved by downgrading Node.js version from 12.14.0 to 10.18.0 and reinstalling node_modules.

Or - build on @Jamaica Geek's answer, using Express - to avoid saving and reading a file:

  res.attachment('file.xls');

  var header="Sl No"+"\t"+" Age"+"\t"+"Name"+"\n";
  var row1 = [0,21,'BOB'].join('\t')
  var row2 = [0,22,'bob'].join('\t');

  var c = header + row1 + row2;
  return res.send(c);

The first arg that you give to grep needs to evaluate as true or false to indicate whether there was a match. So it should be:

# note that grep returns a list, so $matched needs to be in brackets to get the 
# actual value, otherwise $matched will just contain the number of matches
if (my ($matched) = grep $_ eq $match, @array) {
    print "found it: $matched\n";
}

If you need to match on a lot of different values, it might also be worth for you to consider putting the array data into a hash, since hashes allow you to do this efficiently without having to iterate through the list.

# convert array to a hash with the array elements as the hash keys and the values are simply 1
my %hash = map {$_ => 1} @array;

# check if the hash contains $match
if (defined $hash{$match}) {
    print "found it\n";
}

There is the "edge" mode.

<html>
   <head>
      <meta http-equiv="X-UA-Compatible" content="IE=edge" />
      <title>My Web Page</title>
   </head>
   <body>
      <p>Content goes here.</p>
   </body>
</html>

From the linked MSDN page:

Edge mode tells Windows Internet Explorer to display content in the highest mode available, which actually breaks the “lock-in” paradigm. With Internet Explorer 8, this is equivalent to IE8 mode. If a (hypothetical) future release of Internet Explorer supported a higher compatibility mode, pages set to Edge mode would appear in the highest mode supported by that version; however, those same pages would still appear in IE8 mode when viewed with Internet Explorer 8.

However, "edge" mode is not encouraged in production use:

It is recommended that Web developers restrict their use of Edge mode to test pages and other non-production uses because of the possible unexpected results of rendering page content in future versions of Windows Internet Explorer.

I honestly don't entirely understand why. But according to this, the best way to go at the moment is using IE=8.

git rebase -i allows you to conveniently edit any previous commits, except for the root commit. The following commands show you how to do this manually.

# tag the old root, "git rev-list ..." will return the hash of first commit
git tag root `git rev-list HEAD | tail -1`

# switch to a new branch pointing at the first commit
git checkout -b new-root root

# make any edits and then commit them with:
git commit --amend

# check out the previous branch (i.e. master)
git checkout @{-1}

# replace old root with amended version
git rebase --onto new-root root

# you might encounter merge conflicts, fix any conflicts and continue with:
# git rebase --continue

# delete the branch "new-root"
git branch -d new-root

# delete the tag "root"
git tag -d root

\n must be in double quotes!

echo "hello\nworld";

Output

hello
world

A nice way around this is to use PHP as a more of a templating language

<p>
    Hello <span><?php echo $world ?></span>
</p>

Output

<p>
    Hello <span>Planet Earth</span>
</p>

Notice, all newlines are kept in tact!

In full generality, this functionality is impossible. The Java ClassLoader mechanism guarantees only the ability to ask for a class with a specific name (including pacakge), and the ClassLoader can supply a class, or it can state that it does not know that class.

Classes can be (and frequently are) loaded from remote servers, and they can even be constructed on the fly; it is not difficult at all to write a ClassLoader that returns a valid class that implements a given interface for any name you ask from it; a List of the classes that implement that interface would then be infinite in length.

In practice, the most common case is an URLClassLoader that looks for classes in a list of filesystem directories and JAR files. So what you need is to get the URLClassLoader, then iterate through those directories and archives, and for each class file you find in them, request the corresponding Class object and look through the return of its getInterfaces() method.

These answers don't cover very well MULTIPLE variables.

Doing the inline assignment in a stored procedure causes those results to ALSO be sent back in the resultset. That can be confusing. To using the SELECT...INTO syntax with multiple variables you do:

SELECT a, b INTO @a, @b FROM mytable LIMIT 1;

The SELECT must return only 1 row, hence LIMIT 1, although that isn't always necessary.

For php 7.1

sudo apt-get install php7.1-mbstring

I'd like to add a mention of the "brew" package. You can write a brew template file which would be LaTeX with placeholders, and then "brew" it up to create a .tex file to \include or \input into your LaTeX. Something like:

\begin{tabular}{l l}
A & <%= fit$A %> \\
B & <%= fit$B %> \\
\end{tabular}

The brew syntax can also handle loops, so you can create a table row for each row of a dataframe.

That is because you are trying to access the plugin before it's loaded. You should try making a call to it when the DOM is loaded by surrounding it with this:

$(document).ready(function(){
    $("#colorpicker").colorpicker();
}

Git keeps all of its files in the .git directory. Just remove that one and init again.

If you can't find it, it's because it is hidden.

• In Windows 7, you need to go to your folder, click on Organize on the top left, then click on Folder and search options, then click on the View tab and click on the Show hidden files, folders and drives radio button.

• On a Mac OS:

  • Open a Terminal (via Spotlight: press CMD + SPACE, type terminal and press Enter) and run:

    defaults write com.apple.finder AppleShowAllFiles 1 && killall Finder
    

    Note: The keyboard shortcut to show hidden files in Finder is CMD + SHIFT + . so it is no longer necessary to modify the finder config this way

  • You could also type cd (the space is important), drag and drop your git repo folder from Finder to the terminal window, press return, then type rm -fr .git, then return again.

• On Ubuntu, use shortcut Ctrl + H.

If you get the same value for both property and attribute, but still sees it different on the HTML try this to get the HTML one:

$('#inputID').context.defaultValue;

From what I understand you want to make a navigation bar or something similar to it. What I recommend doing is making a list and editing the items from there. Just try this;

<ul>
    <li class='item col-md-12 panel' id='gameplay-title'>Title</li>
    <li class='item col-md-6 col-md-offset-3 panel' id='gameplay-scoreboard'>Scoreboard</li>
</ul>

And so on... To add more categories add another ul in there. Now, for the CSS you just need this;

ul {
    list-style: none;
}
.item {
    display: inline;
    padding-right: 20px;
}

A problem can be that you try to access you session inside of your controller's __constructor() function.

From Laravel 5.3+ this is not possible anymore because it is not intended to work anyway, as stated in the upgrade guide.

In previous versions of Laravel, you could access session variables or the authenticated user in your controller's constructor. This was never intended to be an explicit feature of the framework. In Laravel 5.3, you can't access the session or authenticated user in your controller's constructor because the middleware has not run yet.

For more background information also read Taylor his response.

Workaround

If you still want to use this, you can dynamically create a middleware and run it in the constructor, as described in the upgrade guide:

As an alternative, you may define a Closure based middleware directly in your controller's constructor. Before using this feature, make sure that your application is running Laravel 5.3.4 or above:

<?php

namespace App\Http\Controllers;

use App\User;
use Illuminate\Support\Facades\Auth;
use App\Http\Controllers\Controller;

class ProjectController extends Controller
{
    /**
     * All of the current user's projects.
     */
    protected $projects;

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware(function ($request, $next) {
            $this->projects = Auth::user()->projects;

            return $next($request);
        });
    }
}

Using the python-varname package, you can easily retrieve the name of the variables

https://github.com/pwwang/python-varname

As of v0.6.0, in your case, you can do:

from varname.helpers import Wrapper

foo = Wrapper(dict())

# foo.name == 'foo'
# foo.value == {}
foo.value['bar'] = 2

For list comprehension part, you can do:

n_jobs = Wrapper(<original_value>) 
users = Wrapper(<original_value>) 
queues = Wrapper(<original_value>) 
priorities = Wrapper(<original_value>) 

list_of_dicts = [n_jobs, users, queues, priorities]
columns = [d.name for d in list_of_dicts]
# ['n_jobs', 'users', 'queues', 'priorities']
# REMEMBER that you have to access the <original_value> by d.value

You can also try to retrieve the variable name DIRECTLY:

from varname import nameof

foo = dict()

fooname = nameof(foo)
# fooname == 'foo'

Note that this is working in this case as you expected:

n_jobs = <original_value>
d = n_jobs

nameof(d) # will return d, instead of n_jobs
# nameof only works directly with the variable

I am the author of this package. Please let me know if you have any questions or you can submit issues on Github.

There is a point to only put commands and options in variables.

#! /bin/bash

if [ $# -ne 2 ]
then
    echo "Usage: `basename $0` DIRECTORY BACKUP_DIRECTORY"
    exit 1
fi

. standard_tools    

directory=$1
backup_directory=$2
current_date=$(date +%Y-%m-%dT%H-%M-%S)
backup_file="${backup_directory}/${current_date}.backup"

${tar_create} "${directory}" | ${openssl} | ${split_1024} "$backup_file"

You can relocate the commands to another file you source, so you can reuse the same commands and options across many scripts. This is very handy when you have a lot of scripts and you want to control how they all use tools. So standard_tools would contain:

export tar_create="tar cv"
export openssl="openssl des3 -salt"
export split_1024="split -b 1024m -"

How about something like this:

<script>
function changeQueryVariable(keyString, replaceString) {
    var query = window.location.search.substring(1);
    var vars = query.split("&");
    var replaced = false;
    for (var i = 0; i < vars.length; i++) {
        var pair = vars[i].split("=");
        if (pair[0] == keyString) {
            vars[i] = pair[0] + "="+ replaceString;
            replaced = true;
        }
    }
    if (!replaced) vars.push(keyString + "=" + replaceString);
    return vars.join("&");
}
</script>

you can also print the data onto your HTML/JSP document. like:-

<!DOCTYPE html>
<html>
<head>
    <title>Jsp Sample</title>
    <%@page import="java.sql.*;"%>
</head>

        Statement st=con.createStatement();
        ResultSet rs=st.executeQuery("select * from student;");
    %><table border=1 align=center style="text-align:center">

          <tr>
             <th>ID</th>
             <th>NAME</th>
             <th>SKILL</th>
             <th>ACTION</th>
          </tr>
      </thead>
      <tbody>
        <%while(rs.next())

If you generate classes for multi-dimensional array, there is a bug in XSD.exe generator, but there are workarounds.

Use the below approach to identify dates are sort or not

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

boolean  decendingOrder = true;
    for(int index=0;index<date.size() - 1; index++) {
        if(simpleDateFormat.parse(date.get(index)).getTime() < simpleDateFormat.parse(date.get(index+1)).getTime()) {
            decendingOrder = false;
            break;
        }
    }
    if(decendingOrder) {
        System.out.println("Date are in Decending Order");
    }else {
        System.out.println("Date not in Decending Order");
    }       
}

Try adding return false; in your click callback like this -

$(document).ready(function() {
  $('.popup').click(function(event) {
      window.open($(this).attr("href"), "popupWindow", "width=600,height=600,scrollbars=yes");
      return false;
  });
});

import datetime

def daterange(start, stop, step_days=1):
    current = start
    step = datetime.timedelta(step_days)
    if step_days > 0:
        while current < stop:
            yield current
            current += step
    elif step_days < 0:
        while current > stop:
            yield current
            current += step
    else:
        raise ValueError("daterange() step_days argument must not be zero")

if __name__ == "__main__":
    from pprint import pprint as pp
    lo = datetime.date(2008, 12, 27)
    hi = datetime.date(2009, 1, 5)
    pp(list(daterange(lo, hi)))
    pp(list(daterange(hi, lo, -1)))
    pp(list(daterange(lo, hi, 7)))
    pp(list(daterange(hi, lo, -7))) 
    assert not list(daterange(lo, hi, -1))
    assert not list(daterange(hi, lo))
    assert not list(daterange(lo, hi, -7))
    assert not list(daterange(hi, lo, 7)) 

If you just want to send an enum you can do something like:

First declare an enum containing some value(which can be passed through intent):

 public enum MyEnum {
    ENUM_ZERO(0),
    ENUM_ONE(1),
    ENUM_TWO(2),
    ENUM_THREE(3);
    private int intValue;

    MyEnum(int intValue) {
        this.intValue = intValue;
    }

    public int getIntValue() {
        return intValue;
    }

    public static MyEnum getEnumByValue(int intValue) {
        switch (intValue) {
            case 0:
                return ENUM_ZERO;
            case 1:
                return ENUM_ONE;
            case 2:
                return ENUM_TWO;
            case 3:
                return ENUM_THREE;
            default:
                return null;
        }
    }
}

Then:

  intent.putExtra("EnumValue", MyEnum.ENUM_THREE.getIntValue());

And when you want to get it:

  NotificationController.MyEnum myEnum = NotificationController.MyEnum.getEnumByValue(intent.getIntExtra("EnumValue",-1);

Piece of cake!

Swift 5.0

 myButton2.contentMode = .scaleAspectFit
 myButton2.contentHorizontalAlignment = .fill
 myButton2.contentVerticalAlignment = .fill

Another way to effectively do this is:

git fetch
git branch -d branchB
git branch -t branchB origin/branchB

Because it's a lower case -d, it will only delete it if the data will still exist somewhere. It's similar to @kkoehne's answer except it doesn't force. Because of the -t it will set up the remote again.

I had a slightly different need than OP, which was to create a new feature branch off develop (or master), after merging a pull request. That can be accomplished in a one-liner without force, but it doesn't update the local develop branch. It's just a matter of checking out a new branch and having it be based off origin/develop:

git checkout -b new-feature origin/develop

Try cleaning the project and rebuild, if doesn't work try disabling the Instant Run from Settings>Build>Instant Run in case you are running someone else's code.

One simple solution:

cond1 <- df$sub == 1 & df$day == 2

cond2 <- df$sub == 3 & df$day == 4

df <- df[!(cond1 | cond2),]

Why don't use associative array, so you can use it easily

function unserializeForm($str) {
    $returndata = array();
    $strArray = explode("&", $str);
    $i = 0;
    foreach ($strArray as $item) {
        $array = explode("=", $item);
        $returndata[$array[0]] = $array[1];
    }

    return $returndata;
}

Faced the same problem running on Windows 10 and using the Windows cmd.

Solved it by running the following command in the Anaconda Prompt which comes with Anaconda3 (as administrator):

conda install -c menpo opencv3=3.1.0

Command found on the official website: https://anaconda.org/menpo/opencv3

Inspired by Robert K's solution, strips html tags and prevents executing scripts and eventhandlers like: <img src=fake onerror="prompt(1)"> Tested on latest Chrome, FF, IE (should work from IE9, but haven't tested).

var decodeEntities = (function () {
        //create a new html document (doesn't execute script tags in child elements)
        var doc = document.implementation.createHTMLDocument("");
        var element = doc.createElement('div');

        function getText(str) {
            element.innerHTML = str;
            str = element.textContent;
            element.textContent = '';
            return str;
        }

        function decodeHTMLEntities(str) {
            if (str && typeof str === 'string') {
                var x = getText(str);
                while (str !== x) {
                    str = x;
                    x = getText(x);
                }
                return x;
            }
        }
        return decodeHTMLEntities;
    })();

Simply call:

decodeEntities('<img src=fake onerror="prompt(1)">');
decodeEntities("<script>alert('aaa!')</script>");

By default, Homebrew installs packages to your /usr/local. Macport commands require sudo to install and upgrade (similar to apt-get in Ubuntu).

For more detail:

This site suggests using Hombrew: http://deephill.com/macports-vs-homebrew/

whereas this site lists the advantages of using Macports: http://arstechnica.com/civis/viewtopic.php?f=19&t=1207907

I also switched from Ubuntu recently, and I enjoy using homebrew (it's simple and easy to use!), but if you feel attached to using sudo, Macports might be the better way to go!

Do not run as sudo, just type:

pip3 install boto3==1.7.40 --user

Enjoy

There are two ways to handle exceptions in pytest:

1. Using pytest.raises to write assertions about raised exceptions
2. Using @pytest.mark.xfail

1. Using pytest.raises

From the docs:

In order to write assertions about raised exceptions, you can use pytest.raises as a context manager

Examples:

Asserting just an exception:

import pytest


def test_zero_division():
    with pytest.raises(ZeroDivisionError):
        1 / 0

with pytest.raises(ZeroDivisionError) says that whatever is in the next block of code should raise a ZeroDivisionError exception. If no exception is raised, the test fails. If the test raises a different exception, it fails.

If you need to have access to the actual exception info:

import pytest

def f():
    f()

def test_recursion_depth():
    with pytest.raises(RuntimeError) as excinfo:
        f()
    assert "maximum recursion" in str(excinfo.value)

excinfo is a ExceptionInfo instance, which is a wrapper around the actual exception raised. The main attributes of interest are .type, .value and .traceback.

2. Using @pytest.mark.xfail

It is also possible to specify a raises argument to pytest.mark.xfail.

import pytest

@pytest.mark.xfail(raises=IndexError)
def test_f():
    l = [1, 2, 3]
    l[10]

@pytest.mark.xfail(raises=IndexError) says that whatever is in the next block of code should raise an IndexError exception. If an IndexError is raised, test is marked as xfailed (x). If no exception is raised, the test is marked as xpassed (X). If the test raises a different exception, it fails.

Notes:

• Using pytest.raises is likely to be better for cases where you are testing exceptions your own code is deliberately raising, whereas using @pytest.mark.xfail with a check function is probably better for something like documenting unfixed bugs or bugs in dependencies.

• You can pass a match keyword parameter to the context-manager (pytest.raises) to test that a regular expression matches on the string representation of an exception. (see more)

Your mock is raising the exception just fine, but the error.resp.status value is missing. Rather than use return_value, just tell Mock that status is an attribute:

barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')

Additional keyword arguments to Mock() are set as attributes on the resulting object.

I put your foo and bar definitions in a my_tests module, added in the HttpError class so I could use it too, and your test then can be ran to success:

>>> from my_tests import foo, HttpError
>>> import mock
>>> with mock.patch('my_tests.bar') as barMock:
...     barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')
...     result = my_test.foo()
... 
404 - 
>>> result is None
True

You can even see the print '404 - %s' % error.message line run, but I think you wanted to use error.content there instead; that's the attribute HttpError() sets from the second argument, at any rate.

from: Outline effect to text

.strokeme
{
    color: white;
    text-shadow:
    -1px -1px 0 #000,
    1px -1px 0 #000,
    -1px 1px 0 #000,
    1px 1px 0 #000;  
}

What I know is one reason when “GC overhead limit exceeded” error is thrown when 2% of the memory is freed after several GC cycles

By this error your JVM is signalling that your application is spending too much time in garbage collection. so the little amount GC was able to clean will be quickly filled again thus forcing GC to restart the cleaning process again.

You should try changing the value of -Xmx and -Xms.

Try this :

width:auto;
margin-right:50px;

Use reload for IE and set src for other browsers. (reload does not work on FF) tested on IE 7,8,9 and Firefox

if(navigator.appName == "Microsoft Internet Explorer"){
    window.document.getElementById('iframeId').contentWindow.location.reload(true);
}else {
    window.document.getElementById('iframeId').src = window.document.getElementById('iframeId').src;
}

>>> import sys; print('{0[0]}.{0[1]}'.format(sys.version_info))
3.5

so from the command line:

python -c "import sys; print('{0[0]}.{0[1]}'.format(sys.version_info))"

A BLOB is a Binary Large OBject. It is used to store large quantities of binary data in a database.

You can use it to store any kind of binary data that you want, includes images, video, or any other kind of binary data that you wish to store.

Different DBMSes treat BLOBs in different ways; you should read the documentation of the databases you are interested in to see how (and if) they handle BLOBs.

In psql that would be

\dx

See the manual for details: http://www.postgresql.org/docs/current/static/app-psql.html

Doing it in plain SQL it would be a select on pg_extension:

SELECT * 
FROM pg_extension

http://www.postgresql.org/docs/current/static/catalog-pg-extension.html

Microsoft SQL Server for instance, Schemas refer to a single user and is another level of a container in the order of indicating the server, database, schema, tables, and objects.

For example, when you are intending to update dbo.table_a and the syntax isn't full qualified such as UPDATE table.a the DBMS can't decide to use the intended table. Essentially by default the DBMS will utilize myuser.table_a

To be clearer, I make an example here,

class ClassA {
  class func func1() -> String {
    return "func1"
  }

  static func func2() -> String {
    return "func2"
  }

  /* same as above
  final class func func2() -> String {
    return "func2"
  }
  */
}

static func is same as final class func

Because it is final, we can not override it in subclass as below:

class ClassB : ClassA {
  override class func func1() -> String {
    return "func1 in ClassB"
  }

  // ERROR: Class method overrides a 'final` class method
  override static func func2() -> String {
    return "func2 in ClassB"
  }
}

You could also add listener from XML layout: android:onClick="onRadioButtonClicked" in your <RadioButton/> tag.

<RadioButton android:id="@+id/radio_pirates"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/pirates"
    android:onClick="onRadioButtonClicked"/>

See Android developer SDK- Radio Buttons for details.

When calling a promise defined in a service or in a factory make sure to use service as I could not get response from a promise defined in a factory. This is how I call a promise defined in a service.

myApp.service('serverOperations', function($http) {
        this.get_data = function(user) {
          return $http.post('http://localhost/serverOperations.php?action=get_data', user);
        };
})


myApp.controller('loginCtrl', function($http, $q, serverOperations, user) {        
    serverOperations.get_data(user)
        .then( function(response) {
            console.log(response.data);
            }
        );
})

In Angular 2+, you can set route to default page by adding this route to your route module. In this case login is my target route for the default page.

{path:'',redirectTo:'login', pathMatch: 'full' },

The safest bet is to create a class on those tables and use that. Currently getting something like this to work in all major browsers is unlikely.

Another usage is that you can pass binded function as an argument to another function which is operating under another execution context.

var name = "sample";
function sample(){
  console.log(this.name);
}
var cb = sample.bind(this);

function somefunction(cb){
  //other code
  cb();
}
somefunction.call({}, cb);

You will also get a 404 error if you are using ipv6 and the server only accepts ipv4.

To use ipv4, make a request adding -4:

wget -4 http://www.php.net/get/php-5.4.13.tar.gz/from/this/mirror

i think the easiest way is to use the Adobe PDF reader COM Component

1. right click on your toolbox & select "Choose Items"
2. Select the "COM Components" tab
3. Select "Adobe PDF Reader" then click ok
4. Drag & Drop the control on your form & modify the "src" Property to the PDF files you want to read

i hope this helps

You can follow the annoucements here: http://forums.mysql.com/read.php?38,561817,561817#msg-561817

UPDATE: The MySql for Visual Studio was split from Connector/NET into a separate product, you can pick it (including the debugger) from here https://dev.mysql.com/downloads/windows/visualstudio/1.2.html (still free & open source).

DISCLAIMER: I was the developer who authored the Stored procedures debugger engine for MySQL for Visual Studio product.

Something simpler than what @Milen proposed but it gives YYYY-MM-DD instead of the DD-MM-YYYY you wanted :

SUBSTRING((DT_STR,30, 1252) GETDATE(), 1, 10)

Expression builder screen:

If you're using Windows 7/ 7+.

Here is something you can try.

Check if the installation is proper in CONTROL PANEL of your computer.

Now goto the directory and where you've install the MongoDB. Ideally, it would be in

C:\Program Files\MongoDB\Server\3.6\bin

Then either in the command prompt or in the IDE's terminal. Navigate to the above path ( Ideally your save file) and type

mongod --dbpath

It should work alright!

Use Query.setParameterList(), Javadoc here.

There are four variants to pick from.

I've been using this answer to great effect: Get the property, as a string, from an Expression<Func<TModel,TProperty>>

I realize I already answered this question a while back. The only advantage my other answer has is that it works for static properties. I find the syntax in this answer much more useful because you don't have to create a variable of the type you want to reflect.

Somewhere, you need to tell Apache that people are allowed to see contents of this directory.

<Directory "F:/bar/public">
    Order Allow,Deny
    Allow from All
    # Any other directory-specific stuff
</Directory>

The real problem here is that there is a bug in hibernate where it uses select-list aliases in the where-clause:

Just in case someone lands here looking for answers, go look at the ticket. It took 5 years to fix but in theory it'll be in one of the next releases and then I suspect your issue will go away.

int position = 0;
listview.setItemChecked(position, true);
View wantedView = adapter.getView(position, null, listview);

It happens that I'm just starting to learn coding and I needed something similar as you have just asked in SQLite (I´m using [SQLiteStudio] (3.1.1)).

It happens that you must define the column's 'Constraint' as 'Not Null' then entering your desired definition using 'Default' 'Constraint' or it will not work (I don't know if this is an SQLite or the program requirment).

Here is the code I used:

CREATE TABLE <MY_TABLE> (
<MY_TABLE_KEY>       INTEGER    UNIQUE
                                PRIMARY KEY,
<MY_TABLE_SERIAL>    TEXT       DEFAULT (<MY_VALUE>) 
                                NOT NULL
<THE_REST_COLUMNS>
);

Whether a string can be parsed as a number is a runtime concern. Typescript does not support this use case as it is focused on compile time (not runtime) safety.

Thanks to all, for me this solution worked: Magento 404 page in backoffice after login
