I recently discovered the rather useful sweep function and add it here for the sake of completeness:

sweep

The basic idea is to sweep through an array row- or column-wise and return a modified array. An example will make this clear (source: datacamp):

Let's say you have a matrix and want to standardize it column-wise:

dataPoints <- matrix(4:15, nrow = 4)

# Find means per column with `apply()`
dataPoints_means <- apply(dataPoints, 2, mean)

# Find standard deviation with `apply()`
dataPoints_sdev <- apply(dataPoints, 2, sd)

# Center the points 
dataPoints_Trans1 <- sweep(dataPoints, 2, dataPoints_means,"-")

# Return the result
dataPoints_Trans1
##      [,1] [,2] [,3]
## [1,] -1.5 -1.5 -1.5
## [2,] -0.5 -0.5 -0.5
## [3,]  0.5  0.5  0.5
## [4,]  1.5  1.5  1.5

# Normalize
dataPoints_Trans2 <- sweep(dataPoints_Trans1, 2, dataPoints_sdev, "/")

# Return the result
dataPoints_Trans2
##            [,1]       [,2]       [,3]
## [1,] -1.1618950 -1.1618950 -1.1618950
## [2,] -0.3872983 -0.3872983 -0.3872983
## [3,]  0.3872983  0.3872983  0.3872983
## [4,]  1.1618950  1.1618950  1.1618950

NB: for this simple example the same result can of course be achieved more easily by
apply(dataPoints, 2, scale)

building on @ltamar's answer:
Use summary and munge the output into something useful!

library(tidyr)
library(dplyr)

df %>% 
  summary %>% 
  data.frame %>%
  select(-Var1) %>%
  separate(data=.,col=Freq,into = c('metric','value'),sep = ':') %>%
  rename(column_name=Var2) %>%
  mutate(value=as.numeric(value),
         metric = trimws(metric,'both') 
  ) %>%  
  filter(!is.na(value)) -> metrics

It's not pretty and it is certainly not fast but it gets the job done!

You simply use the apply() function:

R> M <- matrix(1:6, nrow=3, byrow=TRUE)
R> M
     [,1] [,2]
[1,]    1    2
[2,]    3    4
[3,]    5    6
R> apply(M, 1, function(x) 2*x[1]+x[2])
[1]  4 10 16
R> 

This takes a matrix and applies a (silly) function to each row. You pass extra arguments to the function as fourth, fifth, ... arguments to apply().

For z-index to work, you also need to give it a position:

header {
    width: 100%;
    height: 100px;
    background: url(../img/top.png) repeat-x;
    z-index: 110;
    position: relative;
}

I wrote following function to return a default representation 0 or false of a primitive or Number:

/**
 * Retrieves the default value 0 / false for any primitive representative or
 * {@link Number} type.
 *
 * @param type
 *
 * @return
 */
@SuppressWarnings("unchecked")
public static <T> T getDefault(final Class<T> type)
{
    if (type.equals(Long.class) || type.equals(Long.TYPE))
        return (T) new Long(0);
    else if (type.equals(Integer.class) || type.equals(Integer.TYPE))
        return (T) new Integer(0);
    else if (type.equals(Double.class) || type.equals(Double.TYPE))
        return (T) new Double(0);
    else if (type.equals(Float.class) || type.equals(Float.TYPE))
        return (T) new Float(0);
    else if (type.equals(Short.class) || type.equals(Short.TYPE))
        return (T) new Short((short) 0);
    else if (type.equals(Byte.class) || type.equals(Byte.TYPE))
        return (T) new Byte((byte) 0);
    else if (type.equals(Character.class) || type.equals(Character.TYPE))
        return (T) new Character((char) 0);
    else if (type.equals(Boolean.class) || type.equals(Boolean.TYPE))
        return (T) new Boolean(false);
    else if (type.equals(BigDecimal.class))
        return (T) BigDecimal.ZERO;
    else if (type.equals(BigInteger.class))
        return (T) BigInteger.ZERO;
    else if (type.equals(AtomicInteger.class))
        return (T) new AtomicInteger();
    else if (type.equals(AtomicLong.class))
        return (T) new AtomicLong();
    else if (type.equals(DoubleAdder.class))
        return (T) new DoubleAdder();
    else
        return null;
}

I use it in hibernate ORM projection queries when the underlying SQL query returns null instead of 0.

/**
 * Retrieves the unique result or zero, <code>false</code> if it is
 * <code>null</code> and represents a number
 *
 * @param criteria
 *
 * @return zero if result is <code>null</code>
 */
public static <T> T getUniqueResultDefault(final Class<T> type, final Criteria criteria)
{
    final T result = (T) criteria.uniqueResult();

    if (result != null)
        return result;
    else
        return Utils.getDefault(type);
}

One of the many unnecessary complex things about Java making it unintuitive to use. Why instance variables are initialized with default 0 but local are not is not logical. Similar why enums dont have built in flag support and many more options. Java lambda is a nightmare compared to C# and not allowing class extension methods is also a big problem.

Java ecosystem comes up with excuses why its not possible but me as the user / developer i dont care about their excuses. I want easy approach and if they dont fix those things they will loose big in the future since C# and other languages are not waiting to make life of developers more simple. Its just sad to see the decline in the last 10 years since i work daily with Java.

Simply create a LayoutParams object and assign it to your imageView

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(150, 150);
imageView.setLayoutParams(params);

The differences between these values always come down to detailed language-specific rules. What you learn for PHP isn't necessarily true for Python, or Perl, or C, etc. While it is valuable to learn the rules for the language(s) you're working with, relying on them too much is asking for trouble. The trouble comes when the next programmer needs to maintain your code and you've used some construct that takes advantage of some little detail of Null vs. False (for example). Your code should look correct (and conversely, wrong code should look wrong).

Setting CSS width to 1% or 100% of an element according to all specs I could find out is related to the parent. Although Blink Rendering Engine (Chrome) and Gecko (Firefox) at the moment of writing seems to handle that 1% or 100% (make a columns shrink or a column to fill available space) well, it is not guaranteed according to all CSS specifications I could find to render it properly.

One option is to replace table with CSS4 flex divs:

https://css-tricks.com/snippets/css/a-guide-to-flexbox/

That works in new browsers i.e. IE11+ see table at the bottom of the article.

In practice, it usually decides to do a garbage collection. The answer varies depending on lots of factors, like which JVM you're running on, which mode it's in, and which garbage collection algorithm it's using.

I wouldn't depend on it in your code. If the JVM is about to throw an OutOfMemoryError, calling System.gc() won't stop it, because the garbage collector will attempt to free as much as it can before it goes to that extreme. The only time I've seen it used in practice is in IDEs where it's attached to a button that a user can click, but even there it's not terribly useful.

Here is directive from the official examples angular docs v1.5 that shows how to compile html:

.directive('compileHtml', function ($compile) {
  return function (scope, element, attrs) {
    scope.$watch(
      function(scope) {
        return scope.$eval(attrs.compileHtml);
      },
      function(value) {
        element.html(value);
        $compile(element.contents())(scope);
      }
    );
  };
});

Usage:

<div compile-html="item.htmlString"></div>

It will insert item.htmlString property as html any place, like

<li ng-repeat="item in itemList">
    <div compile-html="item.htmlString"></div>

Something worth mentioning...

As noted above by other contributors, using a .bowerrc file with the JSON

{ "directory": "some/path" }

is necessary -- HOWEVER, you may run into an issue on Windows while creating that file. If Windows gives you a message imploring you to add a "file name", simply use a text editor / IDE such as Notepad++.

Add the JSON to an unnamed file, save it as .bowerrc -- you're good to go!

Probably an easy assumption, but I hope this save others the unnecessary headache :)

If you are accessing the live database by using localhost URL then it will not work. Please deploy your service or website on IIS and create URL and then access the database by using new URL, It will work.

• START_STICKY: It will restart the service in case if it terminated and the Intent data which is passed to the onStartCommand() method is NULL. This is suitable for the service which are not executing commands but running independently and waiting for the job.
• START_NOT_STICKY: It will not restart the service and it is useful for the services which will run periodically. The service will restart only when there are a pending startService() calls. It’s the best option to avoid running a service in case if it is not necessary.
• START_REDELIVER_INTENT: It’s same as STAR_STICKY and it recreates the service, call onStartCommand() with last intent that was delivered to the service.

You can know how many arguments were passed to your function and you can check if your second argument is a function or not:

function getData (id, parameters, callback) {
  if (arguments.length == 2) { // if only two arguments were supplied
    if (Object.prototype.toString.call(parameters) == "[object Function]") {
      callback = parameters; 
    }
  }
  //...
}

You can also use the arguments object in this way:

function getData (/*id, parameters, callback*/) {
  var id = arguments[0], parameters, callback;

  if (arguments.length == 2) { // only two arguments supplied
    if (Object.prototype.toString.call(arguments[1]) == "[object Function]") {
      callback = arguments[1]; // if is a function, set as 'callback'
    } else {
      parameters = arguments[1]; // if not a function, set as 'parameters'
    }
  } else if (arguments.length == 3) { // three arguments supplied
      parameters = arguments[1];
      callback = arguments[2];
  }
  //...
}

If you are interested, give a look to this article by John Resig, about a technique to simulate method overloading on JavaScript.

set myPATH="C:\Users\DEB\Downloads\10.1.1.0.4"
cd %myPATH%

• The single quotes do not indicate a string, they make it starts: 'C:\ instead of C:\ so

• %name% is the usual syntax for expanding a variable, the !name! syntax needs to be enabled using the command setlocal ENABLEDELAYEDEXPANSION first, or by running the command prompt with CMD /V:ON.

• Don't use PATH as your name, it is a system name that contains all the locations of executable programs. If you overwrite it, random bits of your script will stop working. If you intend to change it, you need to do set PATH=%PATH%;C:\Users\DEB\Downloads\10.1.1.0.4 to keep the current PATH content, and add something to the end.

This worked fine for me

1. Take a backup
2. Create new database and restore the backup to it
3. Then Properties > Options > [Scroll down] State > RestrictAccess > select Multi_user and click OK
4. Delete the old database

Hope this work for all Thank you Ramesh Kumar

On Xcode Version 8.1 (8B62) it can be done directly in Attributes Inspector. Select the textField and then choose the appropriate option from Clear Button drop down box, which is located in Attributes Inspector.

The usual method I have seen is X.Y.Z, which generally corresponds to major.minor.patch:

• Major version numbers change whenever there is some significant change being introduced. For example, a large or potentially backward-incompatible change to a software package.
• Minor version numbers change when a new, minor feature is introduced or when a set of smaller features is rolled out.
• Patch numbers change when a new build of the software is released to customers. This is normally for small bug-fixes or the like.

Other variations use build numbers as an additional identifier. So you may have a large number for X.Y.Z.build if you have many revisions that are tested between releases. I use a couple of packages that are identified by year/month or year/release. Thus, a release in the month of September of 2010 might be 2010.9 or 2010.3 for the 3rd release of this year.

There are many variants to versioning. It all boils down to personal preference.

For the "1.3v1.1", that may be two different internal products, something that would be a shared library / codebase that is rev'd differently from the main product; that may indicate version 1.3 for the main product, and version 1.1 of the internal library / package.

You can’t call non-static methods from static methods, but by creating an instance inside the static method.

It should work like that

class test2(object):
    def __init__(self):
        pass

    @staticmethod
    def dosomething():
        print "do something"
        # Creating an instance to be able to
        # call dosomethingelse(), or you
        # may use any existing instance
        a = test2()
        a.dosomethingelse()

    def dosomethingelse(self):
        print "do something else"

test2.dosomething()

Usually this is an error in your PHP configuration.

It's actually pretty easy to figure out what exactly is going on:

• Create a small file (test.php) with the standard phpinfo() script
• Open a command prompt
• Start php manually using the small file, e.g. '"\program files\php\php.exe" test.php
• Read the error messages :-)

Asynchronous action methods are useful when an action must perform several independent long running operations.

A typical use for the AsyncController class is long-running Web service calls.

Should my database calls be asynchronous ?

The IIS thread pool can often handle many more simultaneous blocking requests than a database server. If the database is the bottleneck, asynchronous calls will not speed up the database response. Without a throttling mechanism, efficiently dispatching more work to an overwhelmed database server by using asynchronous calls merely shifts more of the burden to the database. If your DB is the bottleneck, asynchronous calls won’t be the magic bullet.

You should have a look at 1 and 2 references

Derived from @PanagiotisKanavos comments:

Moreover, async doesn't mean parallel. Asynchronous execution frees a valuable threadpool thread from blocking for an external resource, for no complexity or performance cost. This means the same IIS machine can handle more concurrent requests, not that it will run faster.

You should also consider that blocking calls start with a CPU-intensive spinwait. During stress times, blocking calls will result in escalating delays and app pool recycling. Asynchronous calls simply avoid this

If you already have the int typed as an Integer you can do this:

Integer y = 1;
long x = y.longValue();

Yes, that's the intuitive answer. Nothing in Spyder is intuitive. Go to Preferences/Editor and select the scheme you want. Then go to Preferences/Syntax Coloring and adjust the colors if you want to. tcebob

Instead of using width (which is a suggestion when using flexbox), you could use flex: 0 0 230px; which means:

• 0 = don't grow (shorthand for flex-grow)
• 0 = don't shrink (shorthand for flex-shrink)
• 230px = start at 230px (shorthand for flex-basis)

which means: always be 230px.

See fiddle, thanks @TylerH

Oh, and you don't need the justify-content and align-items here.

img {
    max-width: 100%;
}
#container {
    display: flex;
    x-justify-content: space-around;
    x-align-items: stretch;
    max-width: 1200px;
}
.column.left {
    width: 230px;
    flex: 0 0 230px;
}
.column.right {
    width: 230px;
    flex: 0 0 230px;
    border-left: 1px solid #eee;
}
.column.center {
    border-left: 1px solid #eee;
}

For copy any text in Android:

            TextView text = findViewById(R.id.text_id);
            ImageView icons = findViewById(R.id.copy_icon);

            icons.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    ClipboardManager clipboardManager = (ClipboardManager)getSystemService(Context.CLIPBOARD_SERVICE);
                    ClipData clipData = ClipData.newPlainText("text whatever you want", text.getText().toString());
                    clipboardManager.setPrimaryClip(clipData);

                    Toast.makeText(context, "Text Copied", Toast.LENGTH_SHORT).show();
                }
            });

Just uninstalled jre-32 bit version and It worked fine for me.

select sum(qty), name
from (
    select count(m.owner_id) as qty, o.name
    from transport t,owner o,motorbike m
    where t.type='motobike' and o.owner_id=m.owner_id
        and t.type_id=m.motorbike_id
    group by m.owner_id

    union all

    select count(c.owner_id) as qty, o.name,
    from transport t,owner o,car c
    where t.type='car' and o.owner_id=c.owner_id and t.type_id=c.car_id
    group by c.owner_id
) t
group by name

This solution showed above works perfect also for selected rows. For example I am creating demonstration rows for my nice2work project, and this works perfect.

CREATE TEMPORARY TABLE tmptable SELECT * FROM myTable WHERE id=500;
UPDATE tmptable SET id = 0;
UPDATE some fields I need to change
INSERT INTO myTable SELECT * FROM tmptable;
DROP TABLE tmptable;

//  You can use this same also directly into your code like (PHP Style)
$sql = "CREATE TEMPORARY TABLE tmptable SELECT * FROM myTable WHERE id=500;
UPDATE tmptable SET id = 0;
UPDATE some fields I need to change
INSERT INTO myTable SELECT * FROM tmptable;DROP TABLE tmptable;";

We can try like this

    recyclerView.getLayoutManager().smoothScrollToPosition(recyclerView,new RecyclerView.State(), recyclerView.getAdapter().getItemCount());

Can you try this, readfile need the full file path.

        $filename='/pdf/jobs/pdffile.pdf';            
        $url_download = BASE_URL . RELATIVE_PATH . $filename;            

        //header("Content-type:application/pdf");   
        header("Content-type: application/octet-stream");                       
        header("Content-Disposition:inline;filename='".basename($filename)."'");            
        header('Content-Length: ' . filesize($filename));
        header("Cache-control: private"); //use this to open files directly                     
        readfile($filename);

This is answered in some of the answers to Can't find how to use HttpContent as well as in this blog post.

In summary, you can't directly set up an instance of HttpContent because it is an abstract class. You need to use one the classes derived from it depending on your need. Most likely StringContent, which lets you set the string value of the response, the encoding, and the media type in the constructor. See: http://msdn.microsoft.com/en-us/library/system.net.http.stringcontent.aspx

I have tried to use the above robot there is a need to add a delay :( also you cannot debug or do something else because you lose the focus :(

//open upload window upload.click();

//put path to your image in a clipboard
StringSelection ss = new StringSelection(file.getAbsoluteFile());
Toolkit.getDefaultToolkit().getSystemClipboard().setContents(ss, null);

//imitate mouse events like ENTER, CTRL+C, CTRL+V
Robot robot = new Robot();
robot.delay(250);
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_ENTER);
robot.delay(50);
robot.keyRelease(KeyEvent.VK_ENTER);

This is a very old post, but I recently encountered the problem and for me the following solved the issue by formatting the SQL as follows,

SELECT CONVERT (varchar, getdate(), 120) AS Date

If you copy the result from SQL Server and paste in Excel then Excel holds the proper formatting.

PHP_EOL is a predefined constant in PHP since PHP 4.3.10 and PHP 5.0.2. See the manual posting:

Using this will save you extra coding on cross platform developments.

IE.

$data = 'some data'.PHP_EOL;
$fp = fopen('somefile', 'a');
fwrite($fp, $data);

If you looped through this twice you would see in 'somefile':

some data
some data

This often occurs when you build software in RHEL 7 and try to run on RHEL 6.

To update GLIBC to any version, simply download the package from

https://ftp.gnu.org/gnu/libc/

For example glibc-2.14.tar.gz in your case.

1. tar xvfz glibc-2.14.tar.gz
2. cd glibc-2.14
3. mkdir build
4. cd build
5. ../configure --prefix=/opt/glibc-2.14
6. make
7. sudo make install
8. export LD_LIBRARY_PATH=/opt/glibc-2.14/lib:$LD_LIBRARY_PATH

Then try to run your software, glibc-2.14 should be linked.

It seems you have the click event wrapped around a custom event name "pageinit", are you sure you're triggered the event before you click the button?

something like this:

$("#gender").trigger("pageinit");

The href property sets or returns the value of the href attribute of a link.

  var hello = domains[i].getElementsByTagName('a')[0].getAttribute('href');
    var url="https://www.google.com/";

Pandas will recognise a value as null if it is a np.nan object, which will print as NaN in the DataFrame. Your missing values are probably empty strings, which Pandas doesn't recognise as null. To fix this, you can convert the empty stings (or whatever is in your empty cells) to np.nan objects using replace(), and then call dropna()on your DataFrame to delete rows with null tenants.

To demonstrate, we create a DataFrame with some random values and some empty strings in a Tenants column:

>>> import pandas as pd
>>> import numpy as np
>>> 
>>> df = pd.DataFrame(np.random.randn(10, 2), columns=list('AB'))
>>> df['Tenant'] = np.random.choice(['Babar', 'Rataxes', ''], 10)
>>> print df

          A         B   Tenant
0 -0.588412 -1.179306    Babar
1 -0.008562  0.725239         
2  0.282146  0.421721  Rataxes
3  0.627611 -0.661126    Babar
4  0.805304 -0.834214         
5 -0.514568  1.890647    Babar
6 -1.188436  0.294792  Rataxes
7  1.471766 -0.267807    Babar
8 -1.730745  1.358165  Rataxes
9  0.066946  0.375640         

Now we replace any empty strings in the Tenants column with np.nan objects, like so:

>>> df['Tenant'].replace('', np.nan, inplace=True)
>>> print df

          A         B   Tenant
0 -0.588412 -1.179306    Babar
1 -0.008562  0.725239      NaN
2  0.282146  0.421721  Rataxes
3  0.627611 -0.661126    Babar
4  0.805304 -0.834214      NaN
5 -0.514568  1.890647    Babar
6 -1.188436  0.294792  Rataxes
7  1.471766 -0.267807    Babar
8 -1.730745  1.358165  Rataxes
9  0.066946  0.375640      NaN

Now we can drop the null values:

>>> df.dropna(subset=['Tenant'], inplace=True)
>>> print df

          A         B   Tenant
0 -0.588412 -1.179306    Babar
2  0.282146  0.421721  Rataxes
3  0.627611 -0.661126    Babar
5 -0.514568  1.890647    Babar
6 -1.188436  0.294792  Rataxes
7  1.471766 -0.267807    Babar
8 -1.730745  1.358165  Rataxes

Always keep in mind that 'size' is variable if not explicitly specified so if you declare

 int i = 10;

On some systems it may result in 16-bit integer by compiler and on some others it may result in 32-bit integer (or 64-bit integer on newer systems).

In embedded environments this may end up in weird results (especially while handling memory mapped I/O or may be consider a simple array situation), so it is highly recommended to specify fixed size variables. In legacy systems you may come across

 typedef short INT16;
 typedef int INT32;
 typedef long INT64; 

Starting from C99, the designers added stdint.h header file that essentially leverages similar typedefs.

On a windows based system, you may see entries in stdin.h header file as

 typedef signed char       int8_t;
 typedef signed short      int16_t;
 typedef signed int        int32_t;
 typedef unsigned char     uint8_t;

There is quite more to that like minimum width integer or exact width integer types, I think it is not a bad thing to explore stdint.h for a better understanding.

Yes of course, just add the response y as first column in the dataframe and call lm() on it:

d2<-data.frame(y,d)
> d2
  y x1 x2 x3
1 1  4  3  4
2 4 -1  9 -4
3 6  3  8 -2
> lm(d2)

Call:
lm(formula = d2)

Coefficients:
(Intercept)           x1           x2           x3  
    -5.6316       0.7895       1.1579           NA  

Also, my information about R points out that assignment with <- is recommended over =.

If you are using unix, you need to write a shellscript to run you java batch first.

After that, in unix, you run this command "crontab -e" to edit crontab script. In order to configure crontab, please refer to this article http://www.thegeekstuff.com/2009/06/15-practical-crontab-examples/

Save your crontab setting. Then wait for the time to come, program will run automatically.

Just to add to RichieHindle's answer, check out Floatutorial, which walks you through how CSS floating and clearing works.

This can be as simple as adding ToList() in your repository. For example:

public IEnumerable<MyObject> GetMyObjectsForId(string id)
{
    using (var ctxt = new RcContext())
    {
        // causes an error
        return ctxt.MyObjects.Where(x => x.MyObjects.Id == id);
    }
}

Will yield the Db Context disposed error in the calling class but this can be resolved by explicitly exercising the enumeration by adding ToList() on the LINQ operation:

public IEnumerable<MyObject> GetMyObjectsForId(string id)
{
    using (var ctxt = new RcContext())
    {
        return ctxt.MyObjects.Where(x => x.MyObjects.Id == id).ToList();
    }
}

This command should help you to find it

php -r "phpinfo();" | grep php.ini

That is a default behaviour of each browser; your browser seems to be Safari, in Google Chrome it is orange in color!

In my case this was because a file named ociw32.dll had been placed in c:\windows\system32. This is however only allowed to exist in c:\oracle\11.2.0.3\bin.

Deleting the file from system32, which had been placed there by an installation of Crystal Reports, fixed this issue

Yes, if bar is not None is more explicit, and thus better, assuming it is indeed what you want. That's not always the case, there are subtle differences: if not bar: will execute if bar is any kind of zero or empty container, or False. Many people do use not bar where they really do mean bar is not None.

I had same problem and despite having jstl

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2</version>
</dependency>

I had to add 'standard' as well:

<dependency>
    <groupId>taglibs</groupId>
    <artifactId>standard</artifactId>
    <version>1.1.2</version>
</dependency>

Also, as mentioned in previous post:

• for version 1.0 use: http://java.sun.com/jstl/core
• for 1.1 (and later) use: http://java.sun.com/jsp/jstl/core

yes..in JAVA

System.out.println(Integer.SIZE/8);  //gives you 4.
System.out.println(Integer.SIZE);   //gives you 32.

//Similary for Byte,Long,Double....

You can use white-space: pre; to make elements act like <pre>, which preserves newlines. Example:

p {_x000D_
  white-space: pre;_x000D_
}

<p>hello _x000D_
How are you</p>

Note for IE that this only works in IE8+.

Beware of recipes like this

target:
    MY_ID=$(GENERATE_ID);
    echo $MY_ID;

It does two things wrong. The first line in the recipe is executed in a separate shell instance from the second line. The variable is lost in the meantime. Second thing wrong is that the $ is not escaped.

target:
    MY_ID=$(GENERATE_ID); \
    echo $$MY_ID;

Both problems have been fixed and the variable is useable. The backslash combines both lines to run in one single shell, hence the setting of the variable and the reading of the variable afterwords, works.

I realize the original post said how to get the results of a shell command into a MAKE variable, and this answer shows how to get it into a shell variable. But other readers may benefit.

One final improvement, if the consumer expects an "environment variable" to be set, then you have to export it.

my_shell_script
    echo $MY_ID

would need this in the makefile

target:
    export MY_ID=$(GENERATE_ID); \
    ./my_shell_script;

Hope that helps someone. In general, one should avoid doing any real work outside of recipes, because if someone use the makefile with '--dry-run' option, to only SEE what it will do, it won't have any undesirable side effects. Every $(shell) call is evaluated at compile time and some real work could accidentally be done. Better to leave the real work, like generating ids, to the inside of the recipes when possible.

on Windows if MySQL is install as a service you can change the binpath of the service. For example

sc config MySQL57 binPath= "\"C:\Program Files\MySQL\MySQL Server 5.7\bin\mysqld.exe\" --defaults-file=\"<myini path>" MySQL57"

space after binpath is important. You must escape double quotes

following script will use to create any kind of file, with user input as extension

import sys
def create():
    print("creating new  file")
    name=raw_input ("enter the name of file:")
    extension=raw_input ("enter extension of file:")
    try:
        name=name+"."+extension
        file=open(name,'a')

        file.close()
    except:
            print("error occured")
            sys.exit(0)

create()

I actually used this script to replace a line of code in the cron file on our company's UNIX servers awhile back. We executed it as normal shell script and had no problems:

#Create temporary file with new line in place
cat /dir/file | sed -e "s/the_original_line/the_new_line/" > /dir/temp_file
#Copy the new file over the original file
mv /dir/temp_file /dir/file

This doesn't go by line number, but you can easily switch to a line number based system by putting the line number before the s/ and placing a wildcard in place of the_original_line.

SELECT  CAST(FLOOR(CAST(DATEADD(d, 1 - DAY(GETDATE()), GETDATE()) AS FLOAT)) AS DATETIME)

If elements are always nearly sorted as in your example then builtin .sort() (timsort) should be fast:

>>> a = [1,1,2]
>>> b = [1,2,2]
>>> a.sort()
>>> b.sort()
>>> a == b
False

If you don't want to sort inplace you could use sorted().

In practice it might always be faster then collections.Counter() (despite asymptotically O(n) time being better then O(n*log(n)) for .sort()). Measure it; If it is important.

Why for? What do you want to iterate? Try this.

call :cpy pc-name-1
call :cpy pc-name-2
...

:cpy
net use \\%1\{destfolder} {password} /user:{username}
copy {file} \\%1\{destfolder}
goto :EOF

You should combine a type pointcut with a method pointcut.

These pointcuts will do the work to find all public methods inside a class marked with an @Monitor annotation:

@Pointcut("within(@org.rejeev.Monitor *)")
public void beanAnnotatedWithMonitor() {}

@Pointcut("execution(public * *(..))")
public void publicMethod() {}

@Pointcut("publicMethod() && beanAnnotatedWithMonitor()")
public void publicMethodInsideAClassMarkedWithAtMonitor() {}

Advice the last pointcut that combines the first two and you're done!

If you're interested, I have written a cheat sheet with @AspectJ style here with a corresponding example document here.

You can change the background of the canvas by doing this:

        if v == i:
            return (k)

sortresult ={}
for i1 in sortvaluelist:

Try using ChromeDriverManager

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager 
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.set_headless()
browser =webdriver.Chrome(ChromeDriverManager().install(),chrome_options=chrome_options)
browser.get('https://google.com')
# capture the screen
browser.get_screenshot_as_file("capture.png")

In addition to all the above, one should note that, for a defined value v:

• String(v) calls v.toString()
• '' + v calls v.valueOf() prior to any other type cast

So we could do something like:

var mixin = {
  valueOf:  function () { return false },
  toString: function () { return 'true' }
};
mixin === false;  // false
mixin == false;    // true
'' + mixin;       // "false"
String(mixin)     // "true"

Tested in FF 34.0 and Node 0.10

There are two primary ways that pandas makes selections from a DataFrame.

• By Label
• By Integer Location

The documentation uses the term position for referring to integer location. I do not like this terminology as I feel it is confusing. Integer location is more descriptive and is exactly what .iloc stands for. The key word here is INTEGER - you must use integers when selecting by integer location.

Before showing the summary let's all make sure that ...

.ix is deprecated and ambiguous and should never be used

There are three primary indexers for pandas. We have the indexing operator itself (the brackets []), .loc, and .iloc. Let's summarize them:

• [] - Primarily selects subsets of columns, but can select rows as well. Cannot simultaneously select rows and columns.
• .loc - selects subsets of rows and columns by label only
• .iloc - selects subsets of rows and columns by integer location only

I almost never use .at or .iat as they add no additional functionality and with just a small performance increase. I would discourage their use unless you have a very time-sensitive application. Regardless, we have their summary:

• .at selects a single scalar value in the DataFrame by label only
• .iat selects a single scalar value in the DataFrame by integer location only

In addition to selection by label and integer location, boolean selection also known as boolean indexing exists.

Examples explaining .loc, .iloc, boolean selection and .at and .iat are shown below

We will first focus on the differences between .loc and .iloc. Before we talk about the differences, it is important to understand that DataFrames have labels that help identify each column and each row. Let's take a look at a sample DataFrame:

df = pd.DataFrame({'age':[30, 2, 12, 4, 32, 33, 69],
                   'color':['blue', 'green', 'red', 'white', 'gray', 'black', 'red'],
                   'food':['Steak', 'Lamb', 'Mango', 'Apple', 'Cheese', 'Melon', 'Beans'],
                   'height':[165, 70, 120, 80, 180, 172, 150],
                   'score':[4.6, 8.3, 9.0, 3.3, 1.8, 9.5, 2.2],
                   'state':['NY', 'TX', 'FL', 'AL', 'AK', 'TX', 'TX']
                   },
                  index=['Jane', 'Nick', 'Aaron', 'Penelope', 'Dean', 'Christina', 'Cornelia'])

All the words in bold are the labels. The labels, age, color, food, height, score and state are used for the columns. The other labels, Jane, Nick, Aaron, Penelope, Dean, Christina, Cornelia are used as labels for the rows. Collectively, these row labels are known as the index.

The primary ways to select particular rows in a DataFrame are with the .loc and .iloc indexers. Each of these indexers can also be used to simultaneously select columns but it is easier to just focus on rows for now. Also, each of the indexers use a set of brackets that immediately follow their name to make their selections.

.loc selects data only by labels

We will first talk about the .loc indexer which only selects data by the index or column labels. In our sample DataFrame, we have provided meaningful names as values for the index. Many DataFrames will not have any meaningful names and will instead, default to just the integers from 0 to n-1, where n is the length(number of rows) of the DataFrame.

There are many different inputs you can use for .loc three out of them are

• A string
• A list of strings
• Slice notation using strings as the start and stop values

Selecting a single row with .loc with a string

To select a single row of data, place the index label inside of the brackets following .loc.

df.loc['Penelope']

This returns the row of data as a Series

age           4
color     white
food      Apple
height       80
score       3.3
state        AL
Name: Penelope, dtype: object

Selecting multiple rows with .loc with a list of strings

df.loc[['Cornelia', 'Jane', 'Dean']]

This returns a DataFrame with the rows in the order specified in the list:

Selecting multiple rows with .loc with slice notation

Slice notation is defined by a start, stop and step values. When slicing by label, pandas includes the stop value in the return. The following slices from Aaron to Dean, inclusive. Its step size is not explicitly defined but defaulted to 1.

df.loc['Aaron':'Dean']

Complex slices can be taken in the same manner as Python lists.

.iloc selects data only by integer location

Let's now turn to .iloc. Every row and column of data in a DataFrame has an integer location that defines it. This is in addition to the label that is visually displayed in the output. The integer location is simply the number of rows/columns from the top/left beginning at 0.

There are many different inputs you can use for .iloc three out of them are

• An integer
• A list of integers
• Slice notation using integers as the start and stop values

Selecting a single row with .iloc with an integer

df.iloc[4]

This returns the 5th row (integer location 4) as a Series

age           32
color       gray
food      Cheese
height       180
score        1.8
state         AK
Name: Dean, dtype: object

Selecting multiple rows with .iloc with a list of integers

df.iloc[[2, -2]]

This returns a DataFrame of the third and second to last rows:

Selecting multiple rows with .iloc with slice notation

df.iloc[:5:3]

Simultaneous selection of rows and columns with .loc and .iloc

One excellent ability of both .loc/.iloc is their ability to select both rows and columns simultaneously. In the examples above, all the columns were returned from each selection. We can choose columns with the same types of inputs as we do for rows. We simply need to separate the row and column selection with a comma.

For example, we can select rows Jane, and Dean with just the columns height, score and state like this:

df.loc[['Jane', 'Dean'], 'height':]

This uses a list of labels for the rows and slice notation for the columns

We can naturally do similar operations with .iloc using only integers.

df.iloc[[1,4], 2]
Nick      Lamb
Dean    Cheese
Name: food, dtype: object

Simultaneous selection with labels and integer location

.ix was used to make selections simultaneously with labels and integer location which was useful but confusing and ambiguous at times and thankfully it has been deprecated. In the event that you need to make a selection with a mix of labels and integer locations, you will have to make both your selections labels or integer locations.

For instance, if we want to select rows Nick and Cornelia along with columns 2 and 4, we could use .loc by converting the integers to labels with the following:

col_names = df.columns[[2, 4]]
df.loc[['Nick', 'Cornelia'], col_names] 

Or alternatively, convert the index labels to integers with the get_loc index method.

labels = ['Nick', 'Cornelia']
index_ints = [df.index.get_loc(label) for label in labels]
df.iloc[index_ints, [2, 4]]

Boolean Selection

The .loc indexer can also do boolean selection. For instance, if we are interested in finding all the rows where age is above 30 and return just the food and score columns we can do the following:

df.loc[df['age'] > 30, ['food', 'score']] 

You can replicate this with .iloc but you cannot pass it a boolean series. You must convert the boolean Series into a numpy array like this:

df.iloc[(df['age'] > 30).values, [2, 4]] 

Selecting all rows

It is possible to use .loc/.iloc for just column selection. You can select all the rows by using a colon like this:

df.loc[:, 'color':'score':2]

The indexing operator, [], can slice can select rows and columns too but not simultaneously.

Most people are familiar with the primary purpose of the DataFrame indexing operator, which is to select columns. A string selects a single column as a Series and a list of strings selects multiple columns as a DataFrame.

df['food']

Jane          Steak
Nick           Lamb
Aaron         Mango
Penelope      Apple
Dean         Cheese
Christina     Melon
Cornelia      Beans
Name: food, dtype: object

Using a list selects multiple columns

df[['food', 'score']]

What people are less familiar with, is that, when slice notation is used, then selection happens by row labels or by integer location. This is very confusing and something that I almost never use but it does work.

df['Penelope':'Christina'] # slice rows by label

df[2:6:2] # slice rows by integer location

The explicitness of .loc/.iloc for selecting rows is highly preferred. The indexing operator alone is unable to select rows and columns simultaneously.

df[3:5, 'color']
TypeError: unhashable type: 'slice'

Selection by .at and .iat

Selection with .at is nearly identical to .loc but it only selects a single 'cell' in your DataFrame. We usually refer to this cell as a scalar value. To use .at, pass it both a row and column label separated by a comma.

df.at['Christina', 'color']
'black'

Selection with .iat is nearly identical to .iloc but it only selects a single scalar value. You must pass it an integer for both the row and column locations

df.iat[2, 5]
'FL'

Through a combination of the suggestions I got, I came up with this:

    private void DrawLetter()
    {
        Graphics g = this.CreateGraphics();

        float width = ((float)this.ClientRectangle.Width);
        float height = ((float)this.ClientRectangle.Width);

        float emSize = height;

        Font font = new Font(FontFamily.GenericSansSerif, emSize, FontStyle.Regular);

        font = FindBestFitFont(g, letter.ToString(), font, this.ClientRectangle.Size);

        SizeF size = g.MeasureString(letter.ToString(), font);
        g.DrawString(letter, font, new SolidBrush(Color.Black), (width-size.Width)/2, 0);

    }

    private Font FindBestFitFont(Graphics g, String text, Font font, Size proposedSize)
    {
        // Compute actual size, shrink if needed
        while (true)
        {
            SizeF size = g.MeasureString(text, font);

            // It fits, back out
            if (size.Height <= proposedSize.Height &&
                 size.Width <= proposedSize.Width) { return font; }

            // Try a smaller font (90% of old size)
            Font oldFont = font;
            font = new Font(font.Name, (float)(font.Size * .9), font.Style);
            oldFont.Dispose();
        }
    }

So far, this works flawlessly.

The only thing I would change is to move the FindBestFitFont() call to the OnResize() event so that I'm not calling it every time I draw a letter. It only needs to be called when the control size changes. I just included it in the function for completeness.

jScrollPane is a good solution to cross browser scrollbars and degrades nicely.

Here's how I do it in a bash script:

if ps ax | grep $0 | grep -v $$ | grep bash | grep -v grep
then
    echo "The script is already running."
    exit 1
fi

This allows me to use this snippet for any bash script. I needed to grep bash because when using with cron, it creates another process that executes it using /bin/sh.

I find the following to work best, called the central error handling approach.

Benefits

You have 2 modes of running your application: Debug and Production. In the Debug mode, the code will stop at any unexpected error and allow you to debug easily by jumping to the line where it occurred by pressing F8 twice. In the Production mode, a meaningful error message will get displayed to the user.

You can throw intentional errors like this, which will stop execution of the code with a message to the user:

Err.Raise vbObjectError, gsNO_DEBUG, "Some meaningful error message to the user"

Err.Raise vbObjectError, gsUSER_MESSAGE, "Some meaningful non-error message to the user"

'Or to exit in the middle of a call stack without a message:
Err.Raise vbObjectError, gsSILENT

Implementation

You need to "wrap" all subroutines and functions with any significant amount of code with the following headers and footers, making sure to specify ehCallTypeEntryPoint in all your entry points. Note the msModule constant as well, which needs to be put in all modules.

Option Explicit
Const msModule As String = "<Your Module Name>"

' This is an entry point 
Public Sub AnEntryPoint()
    Const sSOURCE As String = "AnEntryPoint"
    On Error GoTo ErrorHandler

    'Your code

ErrorExit:
    Exit Sub

ErrorHandler:
    If CentralErrorHandler(Err, ThisWorkbook, msModule, sSOURCE, ehCallTypeEntryPoint) Then
        Stop
        Resume
    Else
        Resume ErrorExit
    End If
End Sub

' This is any other subroutine or function that isn't an entry point
Sub AnyOtherSub()
    Const sSOURCE As String = "AnyOtherSub"
    On Error GoTo ErrorHandler

    'Your code

ErrorExit:
    Exit Sub

ErrorHandler:
    If CentralErrorHandler(Err, ThisWorkbook, msModule, sSOURCE) Then
        Stop
        Resume
    Else
        Resume ErrorExit
    End If
End Sub

The contents of the central error handler module is the following:

So, your first table could have a foreign key of another table that is yet to be created. In such cases, disable foreign_key_checks and create the database.

Just add the following to your script:

SET FOREIGN_KEY_CHECKS=0;

and it shall work.

Use text-center class in the parent container for Bootstrap 4

Use substr:

$str = substr($str, 1); // this is a applepie :)

Sam's solution should be sufficient. I've used combination of both histogram difference and template matching because not one method was working for me 100% of the times. I've given less importance to histogram method though. Here's how I've implemented in simple python script.

import cv2

class CompareImage(object):

    def __init__(self, image_1_path, image_2_path):
        self.minimum_commutative_image_diff = 1
        self.image_1_path = image_1_path
        self.image_2_path = image_2_path

    def compare_image(self):
        image_1 = cv2.imread(self.image_1_path, 0)
        image_2 = cv2.imread(self.image_2_path, 0)
        commutative_image_diff = self.get_image_difference(image_1, image_2)

        if commutative_image_diff < self.minimum_commutative_image_diff:
            print "Matched"
            return commutative_image_diff
        return 10000 //random failure value

    @staticmethod
    def get_image_difference(image_1, image_2):
        first_image_hist = cv2.calcHist([image_1], [0], None, [256], [0, 256])
        second_image_hist = cv2.calcHist([image_2], [0], None, [256], [0, 256])

        img_hist_diff = cv2.compareHist(first_image_hist, second_image_hist, cv2.HISTCMP_BHATTACHARYYA)
        img_template_probability_match = cv2.matchTemplate(first_image_hist, second_image_hist, cv2.TM_CCOEFF_NORMED)[0][0]
        img_template_diff = 1 - img_template_probability_match

        # taking only 10% of histogram diff, since it's less accurate than template method
        commutative_image_diff = (img_hist_diff / 10) + img_template_diff
        return commutative_image_diff


    if __name__ == '__main__':
        compare_image = CompareImage('image1/path', 'image2/path')
        image_difference = compare_image.compare_image()
        print image_difference

A list is unhashable because its contents can change over its lifetime. You can update an item contained in the list at any time.

A list doesn't use a hash for indexing, so it isn't restricted to hashable items.

I eventually used:

weather["Temp"] = weather["Temp"].convert_objects(convert_numeric=True)

It worked just fine, except that I got the following message.

C:\ProgramData\Anaconda3\lib\site-packages\ipykernel_launcher.py:3: FutureWarning:
convert_objects is deprecated.  Use the data-type specific converters pd.to_datetime, pd.to_timedelta and pd.to_numeric.

Something like this should work (untested code warning):

<?php

$html = '<p style="asd">qwe</p><br /><p class="qwe">qweqweqwe</p>';

$domd = new DOMDocument();
libxml_use_internal_errors(true);
$domd->loadHTML($html);
libxml_use_internal_errors(false);

$domx = new DOMXPath($domd);
$items = $domx->query("//p[@style]");

foreach($items as $item) {
  $item->removeAttribute("style");
}

echo $domd->saveHTML();

Using PowerShell, you can use the following

Get-Service | Where-Object {$_.displayName.StartsWith("NATION-")} | Select name

This will show a list off all services which displayname starts with "NATION-".

You can also directly stop or start the services;

Get-Service | Where-Object {$_.displayName.StartsWith("NATION-")} | Stop-Service
Get-Service | Where-Object {$_.displayName.StartsWith("NATION-")} | Start-Service

or simply

Get-Service | Where-Object {$_.displayName.StartsWith("NATION-")} | Restart-Service

The comparison needs to be evaluated fully inside EL ${ ... }, not outside.

<c:if test="${values.type eq 'object'}">

As to the docs, those ${} things are not JSTL, but EL (Expression Language) which is a whole subject at its own. JSTL (as every other JSP taglib) is just utilizing it. You can find some more EL examples here.

<c:if test="#{bean.booleanValue}" />
<c:if test="#{bean.intValue gt 10}" />
<c:if test="#{bean.objectValue eq null}" />
<c:if test="#{bean.stringValue ne 'someValue'}" />
<c:if test="#{not empty bean.collectionValue}" />
<c:if test="#{not bean.booleanValue and bean.intValue ne 0}" />
<c:if test="#{bean.enumValue eq 'ONE' or bean.enumValue eq 'TWO'}" />

See also:

• Our EL wiki page

By the way, unrelated to the concrete problem, if I guess your intent right, you could also just call Object#getClass() and then Class#getSimpleName() instead of adding a custom getter.

<c:forEach items="${list}" var="value">
    <c:if test="${value['class'].simpleName eq 'Object'}">
        <!-- code here -->
    </c:if>
</c:forEeach>

You've already stated why np.maximum is different - it returns an array that is the element-wise maximum between two arrays.

As for np.amax and np.max: they both call the same function - np.max is just an alias for np.amax, and they compute the maximum of all elements in an array, or along an axis of an array.

In [1]: import numpy as np

In [2]: np.amax
Out[2]: <function numpy.core.fromnumeric.amax>

In [3]: np.max
Out[3]: <function numpy.core.fromnumeric.amax>

I looked into this a bit more and the actual problem seems to be with assigning initial to page width under the print media rule. It seems like in Chrome width: initial on the .page element results in scaling of the page content if no specific length value is defined for width on any of the parent elements (width: initial in this case resolves to width: auto ... but actually any value smaller than the size defined under the @page rule causes the same issue).

So not only the content is now too long for the page (by about 2cm), but also the page padding will be slightly more than the initial 2cm and so on (it seems to render the contents under width: auto to the width of ~196mm and then scale the whole content up to the width of 210mm ~ but strangely exactly the same scaling factor is applied to contents with any width smaller than 210mm).

To fix this problem you can simply in the print media rule assign the A4 paper width and hight to html, body or directly to .page and in this case avoid the initial keyword.

DEMO

@page {
  size: A4;
  margin: 0;
}
@media print {
  html, body {
    width: 210mm;
    height: 297mm;
  }
  /* ... the rest of the rules ... */
}

^{This seems to keep everything else the way it is in your original CSS and fix the problem in Chrome (tested in different versions of Chrome under Windows, OS X and Ubuntu).}

You can use merge to combine two dataframes into one:

import pandas as pd
pd.merge(restaurant_ids_dataframe, restaurant_review_frame, on='business_id', how='outer')

where on specifies field name that exists in both dataframes to join on, and how defines whether its inner/outer/left/right join, with outer using 'union of keys from both frames (SQL: full outer join).' Since you have 'star' column in both dataframes, this by default will create two columns star_x and star_y in the combined dataframe. As @DanAllan mentioned for the join method, you can modify the suffixes for merge by passing it as a kwarg. Default is suffixes=('_x', '_y'). if you wanted to do something like star_restaurant_id and star_restaurant_review, you can do:

 pd.merge(restaurant_ids_dataframe, restaurant_review_frame, on='business_id', how='outer', suffixes=('_restaurant_id', '_restaurant_review'))

The parameters are explained in detail in this link.

To get Token Device you can do by some steps:

1) Enable APNS (Apple Push Notification Service) for both Developer Certification and Distribute Certification, then redownload those two file.

2) Redownload both Developer Provisioning and Distribute Provisioning file.

3) In Xcode interface: setting provisioning for PROJECT and TARGETS with two file provisioning have download.

4) Finally, you need to add the code below in AppDelegate file to get Token Device (note: run app in real device).

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
     [self.window addSubview:viewController.view];
     [self.window makeKeyAndVisible];

     NSLog(@"Registering for push notifications...");    
     [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
 (UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
     return YES;
}

- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken { 
     NSString *str = [NSString stringWithFormat:@"Device Token=%@",deviceToken];
     NSLog(@"%@", str);
}

- (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err { 
     NSString *str = [NSString stringWithFormat: @"Error: %@", err];
     NSLog(@"%@",str);
}

for :hover event animations we can left the styles inside svg file, like a

<svg xmlns="http://www.w3.org/2000/svg">
<defs>
  <style>
  rect {
    fill:rgb(165,225,75);
    stroke:none;
    transition: 550ms ease-in-out;
    transform-origin:125px 125px;
  }
  rect:hover {
    fill:rgb(75,165,225);
    transform:rotate(360deg);
  }
  </style>
</defs>
  <rect x='50' y='50' width='150' height='150'/>

custom print function

you can write custom print function and pass ... args to it and it is also possible to combine this with methods above. source from here

int print_custom(const char* format, ...)
{
    static char loc_buf[64];
    char* temp = loc_buf;
    int len;
    va_list arg;
    va_list copy;
    va_start(arg, format);
    va_copy(copy, arg);
    len = vsnprintf(NULL, 0, format, arg);
    va_end(copy);
    if (len >= sizeof(loc_buf)) {
        temp = (char*)malloc(len + 1);
        if (temp == NULL) {
            return 0;
        }
    }
    vsnprintf(temp, len + 1, format, arg);
    printf(temp); // replace with any print function you want
    va_end(arg);
    if (len >= sizeof(loc_buf)) {
        free(temp);
    }
    return len;
}

I also found that you can change the fonts for printing which is controlled by the "Printing" theme. I wanted the print output to be the same as the default, but with a larger font.

1. rename "printing" to "printing1" (select the printing theme and click on it and it should allow you to change the name).

2. click the "+" and select "Default" from the "New Theme From Template" selection

3. rename it "Printing"

4. click in the font area for "Source Editor" and cmd-A to select all of the fonts

5. change the font size to some desired value (I like 12 point) by clicking the "T" icon and selecting the desired font size

After this the printouts should match the new "Printing" template (i.e. in color and bigger, or however you make the template), the key is that printing takes its formating from the "Printing" Theme.

To add to the answers above: if you want to stop Dyno using admin panel, the current solution on free tier:

1. Open App
2. In Overview tab, in "Dyno formation" section click on "Configure Dynos"
3. In the needed row of "Free Dynos" section, click on the pencil icon on the right
4. Click on the blue on/off control, and then click on "Confirm"

Hope this helps.

Just remove all the folders named AndroidStudioPreview

On Windows:

Go to your User Folder - on Windows 7/8 this would be:

[SYSDRIVE]:\Users[your username] (ex. C:\Users\JohnDoe)

In this folder there should be a folder called .AndroidStudioPreview

On Mac OS X

Remove these files:

~/Library/Application Support/AndroidStudioPreview ~/Library/Caches/AndroidStudioPreview ~/Library/Logs/AndroidStudioPreview ~/Library/Preferences/AndroidStudioPreview

You need to set the text after the replace call:

$('.element span').each(function() {_x000D_
  console.log($(this).text());_x000D_
  var text = $(this).text().replace('N/A, ', '');_x000D_
  $(this).text(text);_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<div class="element">_x000D_
  <span>N/A, Category</span>_x000D_
</div>

Here's another cool way you can do it (hat tip @Felix King):

$(".element span").text(function(index, text) {
    return text.replace("N/A, ", "");
});

This problem was solved by following steps -

1. Go to the local m2 repository and find the directory org/apache/maven/plugins/maven-surefire-plugin.
2. Delete the problematic version.
3. maven update the project, then download it again.

For make a list, simply do that

colors=(red orange white "light gray")

Technically is an array, but - of course - it has all list features.
Even python list are implemented with array

Depends in how you are hiding your div, diplay=none is different of visibility=hidden and the opacity=0

• Visibility then use ...style.visibility='visible'

• Display then use ...style.display='block' (or others depends how
  you setup ur css, inline, inline-block, flex...)

• Opacity then use ...style.opacity='1';

Sure you just need to setup a local web server. Check out XAMPP: http://www.apachefriends.org/en/xampp.html

That will get you up and running in about 10 minutes.

There is now a way to run php locally without installing a server: https://stackoverflow.com/a/21872484/672229

Yes but the files need to be processed. For example you can install test servers like mamp / lamp / wamp depending on your plateform.

Basically you need apache / php running.

This is an old topic, but in case anyone else is still looking...

I was having trouble after an undock event. An open db connection saved in a global object would error, even after reconnecting to the network. This was due to the TCP connection being forcibly terminated by remote host. (Error -2147467259: TCP Provider: An existing connection was forcibly closed by the remote host.)

However, the error would only show up after the first transaction was attempted. Up to that point, neither Connection.State nor Connection.Version (per solutions above) would reveal any error.

So I wrote the small sub below to force the error - hope it's useful.

Performance testing on my setup (Access 2016, SQL Svr 2008R2) was approx 0.5ms per call.

Function adoIsConnected(adoCn As ADODB.Connection) As Boolean

    '----------------------------------------------------------------
    '#PURPOSE: Checks whether the supplied db connection is alive and
    '          hasn't had it's TCP connection forcibly closed by remote
    '          host, for example, as happens during an undock event
    '#RETURNS: True if the supplied db is connected and error-free, 
    '          False otherwise
    '#AUTHOR:  Belladonna
    '----------------------------------------------------------------

    Dim i As Long
    Dim cmd As New ADODB.Command

    cmd.CommandText = "SELECT 1"
    cmd.ActiveConnection = adoCn

    'Run a simple query, to test the connection
    On Error Resume Next
    i = cmd.Execute.Fields(0)
    On Error GoTo 0

    'Tidy up
    Set cmd = Nothing

    'If i is 1, connection is open
    If i = 1 Then
        adoIsConnected = True
    Else
        adoIsConnected = False
    End If

End Function

I was going to go with Jason's answer but I noticed that in My version of Xcode (4.3.3) I couldn't do that. so after a bit of research I found they had recently changed the class methods and removed all the old ones. so here's how I had to do it:

NSNumberFormatter *fmt = [[NSNumberFormatter alloc] init];

[fmt setMaximumFractionDigits:2];
NSLog(@"%@", [fmt stringFromNumber:[NSNumber numberWithFloat:25.342]]);

 Constant   Value               Description
 ----------------------------------------------------------------
 vbCr       Chr(13)             Carriage return
 vbCrLf     Chr(13) & Chr(10)   Carriage return–linefeed combination
 vbLf       Chr(10)             Line feed

• vbCr : - return to line beginning
  Represents a carriage-return character for print and display functions.

• vbCrLf : - similar to pressing Enter
  Represents a carriage-return character combined with a linefeed character for print and display functions.

• vbLf : - go to next line
  Represents a linefeed character for print and display functions.

Read More from Constants Class

this is not the very clean and smart way but its very easy to understand and use somtimes - its like odd and even - boolean like:

  var moreOrLess = 2;

  $('.Btn').on('click',function(){

     if(moreOrLess % 2 == 0){
        $(this).text('text1');
        moreOrLess ++ ;
     }else{
        $(this).text('more'); 
        moreOrLess ++ ;
     }

});

Router:-

...
.when('/enquiry/:page', {
    template: '<div ng-include src="templateUrl" onload="onLoad()"></div>',
    controller: 'enquiryCtrl'
})
...

Controller:-

...
// template onload event
$scope.onLoad = function() {
    console.log('onLoad()');
    f_tcalInit();  // or other onload stuff
}

// initialize
$scope.templateUrl = 'ci_index.php/adminctrl/enquiry/'+$routeParams.page;
...

I believe it is a weakness in angularjs that $routeParams is NOT visible inside the router. A tiny enhancement would make a world of difference during implementation.

I just ran into another cause for this error that you can check for.

The base class defined a pure virtual function as:

virtual int foo(int x = 0);

And the subclass had

int foo(int x) override;

The problem was the typo that the "=0" was supposed to be outside of the parenthesis:

virtual int foo(int x) = 0;

So, in case you're scrolling this far down, you probably didn't find the answer - this is something else to check for.

If you have your CSS in an external file, then it's often convenient to display an image that's used frequently across the site (such as a header image) as a background image, because then you have the flexibility to change the image later.

For example, say you have the following HTML:

<div id="headerImage"></div>

...and CSS:

#headerImage {
    width: 200px;
    height: 100px;
    background: url(Images/headerImage.png) no-repeat;
}

A few days later, you change the location of the image. All you have to do is update the CSS:

#headerImage {
    width: 200px;
    height: 100px;
    background: url(../resources/images/headerImage.png) no-repeat;
}

Otherwise, you'd have to update the src attribute of the appropriate <img> tag in every HTML file (assuming you're not using a server-side scripting language or CMS to automate the process).

Also background images are useful if you don't want the user to be able to save the image (although I haven't ever needed to do this).

Dim P As String = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().CodeBase)
P = New Uri(P).LocalPath

Try to delete the maven folder at ~/.m2/repository/org/apache/maven and build your project again to force the maven libraries be downloaded. This worked for me the last time I faced this java.lang.NoClassDefFoundError: org/apache/maven/shared/filtering/MavenFilteringException.

There are a number of possible ways to do this, but have a google for tkprof

There's no GUI... it's entirely command line and possibly a touch intimidating for Oracle beginners; but it's very powerful.

This link looks like a good start:

http://www.oracleutilities.com/OSUtil/tkprof.html

you can look for the jar file as soon as you login to hive

jar:file:/opt/mapr/hive/hive-0.12/lib/hive-common-0.12-mapr-1401-140130.jar!/hive-log4j.properties

The (un)safe way to do this - if you are ok with not using option explicit - is...

Not TypeName(myObj) = "Empty"

This also handles the case if the object has not been declared. This is useful if you want to just comment out a declaration to switch off some behaviour...

Dim myObj as Object
Not TypeName(myObj) = "Empty"  '/ true, the object exists - TypeName is Object

'Dim myObj as Object
Not TypeName(myObj) = "Empty"  '/ false, the object has not been declared

This works because VBA will auto-instantiate an undeclared variable as an Empty Variant type. It eliminates the need for an auxiliary Boolean to manage the behaviour.

As stated already within another answer it is not recommended to catch a NullPointerException. However you definitely could catch it, like the following example shows.

public class Testclass{

    public static void main(String[] args) {
        try {
            doSomething();
        } catch (NullPointerException e) {
            System.out.print("Caught the NullPointerException");
        }
    }

    public static void doSomething() {
        String nullString = null;
        nullString.endsWith("test");
    }
}

Although a NPE can be caught you definitely shouldn't do that but fix the initial issue, which is the Check_Circular method.

To get the currently logged in user:

System.getProperty("user.name"); //platform independent 

and the hostname of the machine:

java.net.InetAddress localMachine = java.net.InetAddress.getLocalHost();
System.out.println("Hostname of local machine: " + localMachine.getHostName());

(Update: a few years later Google and Qwant "airlines" still send me here when searching for "git non-default ssh port") A probably better way in newer git versions is to use the GIT_SSH_COMMAND ENV.VAR like:

GIT_SSH_COMMAND="ssh -oPort=1234 -i ~/.ssh/myPrivate_rsa.key" \ git clone myuser@myGitRemoteServer:/my/remote/git_repo/path

This has the added advantage of allowing any other ssh suitable option (port, priv.key, IPv6, PKCS#11 device, ...).

Try this code as below

var a = [5, 17, 29, 48, 64, 21];
function sortA(arr) {
return arr.sort(function(a, b) {
return a - b;
})
;} 
alert(sortA(a));

I think the beginning to the resolution to this issue is the fact that the use of the for loop or any other function or action can not be done in the class definition but needs to be included in a method/constructor/block definition inside of a class.

Make sure you format the string like this or it wont work

 $content = "BEGIN:VCALENDAR\n".
            "VERSION:2.0\n".
            "PRODID:-//hacksw/handcal//NONSGML v1.0//EN\n".

I didn't have ldd on my ARM toolchain so I used objdump:

Another approach is to first do a searchType: 'count', then and then do a normal search with size set to results.count.

The advantage here is it avoids depending on a magic number for UPPER_BOUND as suggested in this similar SO question, and avoids the extra overhead of building too large of a priority queue that Shay Banon describes here. It also lets you keep your results sorted, unlike scan.

The biggest disadvantage is that it requires two requests. Depending on your circumstance, this may be acceptable.

Just try to set CPU/ABI on "Intel Atom (x86)" and deactivate the checkbox "Use Host GPU".

I managed to get this working using the code from @jluckyiv's answer but I had to add in @JavascriptInterface annotation to the processHTML method in the MyJavaScriptInterface.

class MyJavaScriptInterface
{
    @SuppressWarnings("unused")
    @JavascriptInterface
    public void processHTML(String html)
    {
        // process the html as needed by the app
    }
}

It is simple just write java -XshowSettings:properties on your command line in windows and then paste all the files in the path shown by the java.library.path.

As of Excel 2019 you could do this. The "Error" at the end is the default.

SWITCH(LEFT(A1,1), "A", "Pick Up", "B", "Collect", "C", "Prepaid", "Error")

2018 Update

Now you can use just window.scrollTo({ top: 0, behavior: 'smooth' }) to get the page scrolled with a smooth effect.

const btn = document.getElementById('elem');_x000D_
_x000D_
btn.addEventListener('click', () => window.scrollTo({_x000D_
  top: 400,_x000D_
  behavior: 'smooth',_x000D_
}));

#x {_x000D_
  height: 1000px;_x000D_
  background: lightblue;_x000D_
}

<div id='x'>_x000D_
  <button id='elem'>Click to scroll</button>_x000D_
</div>

Older solutions

You can do something like this:

var btn = document.getElementById('x');_x000D_
_x000D_
btn.addEventListener("click", function() {_x000D_
  var i = 10;_x000D_
  var int = setInterval(function() {_x000D_
    window.scrollTo(0, i);_x000D_
    i += 10;_x000D_
    if (i >= 200) clearInterval(int);_x000D_
  }, 20);_x000D_
})

body {_x000D_
  background: #3a2613;_x000D_
  height: 600px;_x000D_
}

<button id='x'>click</button>

ES6 recursive approach:

const btn = document.getElementById('elem');_x000D_
_x000D_
const smoothScroll = (h) => {_x000D_
  let i = h || 0;_x000D_
  if (i < 200) {_x000D_
    setTimeout(() => {_x000D_
      window.scrollTo(0, i);_x000D_
      smoothScroll(i + 10);_x000D_
    }, 10);_x000D_
  }_x000D_
}_x000D_
_x000D_
btn.addEventListener('click', () => smoothScroll());

body {_x000D_
  background: #9a6432;_x000D_
  height: 600px;_x000D_
}

<button id='elem'>click</button>

DateTime.now.strftime("%Q")

Example usage:

>> DateTime.now.strftime("%Q")
=> "1541433332357"

>> DateTime.now.strftime("%Q").to_i
=> 1541433332357

SELECT * FROM a WHERE a.group_id IN 
(SELECT group_id FROM b WHERE b.user_id!=$_SESSION{'[user_id']} AND b.group_id = a.group_id)
WHERE a.keyword LIKE '%".$keyword."%';

var a = [1,2,3,4,5,6]; 
console.log(a.reverse().slice(1).reverse());
//Array(5) [ 1, 2, 3, 4, 5 ]

simple example of a function parent_by_selector which return a parent or null (no selector matches):

function parent_by_selector(node, selector, stop_selector = 'body') {
  var parent = node.parentNode;
  while (true) {
    if (parent.matches(stop_selector)) break;
    if (parent.matches(selector)) break;
    parent = parent.parentNode; // get upper parent and check again
  }
  if (parent.matches(stop_selector)) parent = null; // when parent is a tag 'body' -> parent not found
  return parent;
};

Use strtotime to convert any date to unix timestamp and compare.

More info on this link: http://www.mokasocial.com/2011/07/sexily-styled-toggle-buttons-for-android/

<ToggleButton 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/toggle_me"/>

and the drawable will be something like:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="true"
        android:drawable="@drawable/toggle_me_on" /> <!-- checked -->
    <item android:drawable="@drawable/toggle_me_off" /> <!-- default/unchecked -->
</selector>

Another option is to use a list comprehension:

df['First Season'] = [1 if year > 1990 else year for year in df['First Season']]

Just one more point in favor of the foo == NULL practice: If foo is, say, an int * or a bool *, then the if (foo) check can accidentally be interpreted by a reader as testing the value of the pointee, i.e. as if (*foo). The NULL comparison here is a reminder that we're talking about a pointer.

But I suppose a good naming convention makes this argument moot.

You are trying to set the timezone for date_time which already has a timezone. Use replace and astimezone functions.

local_tz = pytz.timezone('Asia/Kolkata')

current_time = datetime.now().replace(tzinfo=pytz.utc).astimezone(local_tz)

Try this Using moment.js (Its quite easy to compute date operations in javascript)

firstDate.diff(secondDate, 'days', false);// true|false for fraction value

Result will give you number of days in integer.

In simple English from GROUP BY with two parameters what we are doing is looking for similar value pairs and get the count to a 3rd column.

Explanation: The meaning of the first row is there were 11 Friendly tournaments held on Southern Rhodesia in total.

Note: Here it's mandatory to use a counter column in this case.

Something like this should do the trick

<select id="leave" onchange="leaveChange()">
  <option value="5">Get Married</option>
  <option value="100">Have a Baby</option>
  <option value="90">Adopt a Child</option>
  <option value="15">Retire</option>
  <option value="15">Military Leave</option>
  <option value="15">Medical Leave</option>
</select>

<div id="message"></div>

Javascript

function leaveChange() {
    if (document.getElementById("leave").value != "100"){
        document.getElementById("message").innerHTML = "Common message";
    }     
    else{
        document.getElementById("message").innerHTML = "Having a Baby!!";
    }        
}

jsFiddle Demo

A shorter version and more general could be

HTML

<select id="leave" onchange="leaveChange(this)">
  <option value="5">Get Married</option>
  <option value="100">Have a Baby</option>
  <option value="90">Adopt a Child</option>
  <option value="15">Retire</option>
  <option value="15">Military Leave</option>
  <option value="15">Medical Leave</option>
</select>

Javascript

function leaveChange(control) {
    var msg = control.value == "100" ? "Having a Baby!!" : "Common message";
    document.getElementById("message").innerHTML = msg;
}

Just remove the href attribute from the anchor tag.

Use this script for redis >=5:

#!/bin/bash
redis-cli keys "*" > keys.txt
cat keys.txt | awk '{ printf "type %s\n", $1 }' | redis-cli > types.txt
paste -d'|' keys.txt types.txt | awk -F\| '
   $2 == "string"               { printf "echo \"KEY %s %s\"\nget %s\n", $1, $2, $1 }
   $2 == "list" || $2 == "set"  { printf "echo \"KEY %s %s\"\nsort %s by nosort\n", $1, $2, $1 }
   $2 == "hash"                 { printf "echo \"KEY %s %s\"\nhgetall %s\n", $1, $2, $1 }
   $2 == "zset"                 { printf "echo \"KEY %s %s\"\nzrange %s 0 -1 withscores\n", $1, $2,$1 }
' | redis-cli
rm keys.txt
rm types.txt

These two style of filtering are equivalent in most cases, but when query on objects base on ForeignKey or ManyToManyField, they are slightly different.

Examples from the documentation.

model
Blog to Entry is a one-to-many relation.

from django.db import models

class Blog(models.Model):
    ...

class Entry(models.Model):
    blog = models.ForeignKey(Blog)
    headline = models.CharField(max_length=255)
    pub_date = models.DateField()
    ...

objects
Assuming there are some blog and entry objects here.

queries

Blog.objects.filter(entry__headline_contains='Lennon', 
    entry__pub_date__year=2008)
Blog.objects.filter(entry__headline_contains='Lennon').filter(
    entry__pub_date__year=2008)  
    

For the 1st query (single filter one), it match only blog1.

For the 2nd query (chained filters one), it filters out blog1 and blog2.
The first filter restricts the queryset to blog1, blog2 and blog5; the second filter restricts the set of blogs further to blog1 and blog2.

And you should realize that

We are filtering the Blog items with each filter statement, not the Entry items.

So, it's not the same, because Blog and Entry are multi-valued relationships.

Reference: https://docs.djangoproject.com/en/1.8/topics/db/queries/#spanning-multi-valued-relationships
If there is something wrong, please correct me.

Edit: Changed v1.6 to v1.8 since the 1.6 links are no longer available.

You can bulk import all aliases from one keystore to another:

keytool -importkeystore -srckeystore source.jks -destkeystore dest.jks

Since this is one of the top search results for questions related to this I felt it was worth mentioning how you can make this work with Kendo().DropDownListFor() as well.

Everything is the same as with OnaBai's post except for how you select the item based off of its text and your selector.

To do that you would swap out dataItem.symbol for dataItem.[DataTextFieldName]. Whatever model field you used for .DataTextField() is what you will be comparing against.

@(Html.Kendo().DropDownListFor(model => model.Status.StatusId)
    .Name("Status.StatusId")
    .DataTextField("StatusName")
    .DataValueField("StatusId")
    .BindTo(...)
)

//So that your ViewModel gets bound properly on the post, naming is a bit 
//different and as such you need to replace the periods with underscores
var ddl = $('#Status_StatusId').data('kendoDropDownList');    

ddl.select(function(dataItem) {
    return dataItem.StatusName === "Active";
});

use in the script:

echo $(python python_script.py arg1 arg2) > /dev/null

or

python python_script.py "string arg"  > /dev/null

The script will be executed without output.

I did not test, but there's a javascript implementation of ZIP, called JSZip:

https://stuk.github.io/jszip/

Use a vertical bar (|) for "or".

case "$C" in
"1")
    do_this()
    ;;
"2" | "3")
    do_what_you_are_supposed_to_do()
    ;;
*)
    do_nothing()
    ;;
esac

There is also subset which might be useful sometimes:

a <- sample(1:10)
bad <- c(2, 3, 5)

> subset(a, !(a %in% bad))
[1]  9  7 10  6  8  1  4

You can't specify a range in the case statement, can do as follows.

case 1:
case 2:
case 3:
case 4:
case 5:
case 6:
case 7:
case 8:
   MessageBox.Show("You are only " + age + " years old\n You must be kidding right.\nPlease fill in your *real* age.");
break;

case 9:
case 10:
case 11:
case 12:
case 13:
case 14:
case 15:
   MessageBox.Show("You are only " + age + " years old\n That's too young!");
   break;

...........etc.

For me, turns out I was setting Access-Control-Allow-Origin response header to a specific (and the correct) host.com but it had to be returned as http://host.com instead. What does firefox do? It silently swallows the GET request and returns a status 0 to the XHR, with no warnings output to the javascript console, whereas for other similar failures it would at least say something. Ai ai.

You can iterate through the array or you can convert it to a String and use indexOf.

if (new String(charArray).indexOf('q') < 0) {
    break;
}

Creating a new String is a bit wasteful, but it's probably the tersest code. You can also write a method to imitate the effect without incurring the overhead.

My bad, I had missed one part of the question.

Best, cleanest way is to use a UDF. Explanation within the code.

// create some example data...BY DataFrame
// note, third record has an empty string
case class Stuff(a:String,b:Int)
val d= sc.parallelize(Seq( ("a",1),("b",2),
     ("",3) ,("d",4)).map { x => Stuff(x._1,x._2)  }).toDF

// now the good stuff.
import org.apache.spark.sql.functions.udf
// function that returns 0 is string empty 
val func = udf( (s:String) => if(s.isEmpty) 0 else 1 )
// create new dataframe with added column named "notempty"
val r = d.select( $"a", $"b", func($"a").as("notempty") )

    scala> r.show
+---+---+--------+
|  a|  b|notempty|
+---+---+--------+
|  a|  1|    1111|
|  b|  2|    1111|
|   |  3|       0|
|  d|  4|    1111|

The PDF/pdflib extension documentation in PHP is sparse (something that has been noted in bugs.php.net) - I reccommend you use the Zend library.

if the entity contains a lot of entries the best way is like this because it saves memory

 - (void)deleteAll:(NSManagedObjectContext *)managedObjectContext entityName:(NSString *)entityName
{
    NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
    [managedObjectContext setUndoManager:nil];
    NSEntityDescription *entity = [NSEntityDescription entityForName:entityName inManagedObjectContext:managedObjectContext];
    [fetchRequest setEntity:entity];
    [fetchRequest setIncludesPropertyValues:NO];
    [fetchRequest setFetchLimit:100]; // you can change this number if you want
    NSError *error;
    NSArray *items = [managedObjectContext executeFetchRequest:fetchRequest error:&error];
    while ([items count] > 0) {
        @autoreleasepool {
            for (NSManagedObject *item in items) {
                [managedObjectContext deleteObject:item];
            }
            if (![managedObjectContext save:&error]) {
                NSLog(@"Error deleting %@ - error:%@",self.entityName, error);
            }
        }
        items = [managedObjectContext executeFetchRequest:fetchRequest error:&error];
    }
}

So, whenever I hear someone mention that they want to filter out text, I immediately think to go to Streams (mainly because there is a method called filter which filters exactly as you need it to). Another answer mentions using Streams with the Apache commons-io library, but I thought it would be worthwhile to show how this can be done in standard Java 8. Here is the simplest form:

public void removeLine(String lineContent) throws IOException
{
    File file = new File("myFile.txt");
    List<String> out = Files.lines(file.toPath())
                        .filter(line -> !line.contains(lineContent))
                        .collect(Collectors.toList());
    Files.write(file.toPath(), out, StandardOpenOption.WRITE, StandardOpenOption.TRUNCATE_EXISTING);
}

I think there isn't too much to explain there, basically Files.lines gets a Stream<String> of the lines of the file, filter takes out the lines we don't want, then collect puts all of the lines of the new file into a List. We then write the list over top of the existing file with Files.write, using the additional option TRUNCATE so the old contents of the file are replaced.

Of course, this approach has the downside of loading every line into memory as they all get stored into a List before being written back out. If we wanted to simply modify without storing, we would need to use some form of OutputStream to write each new line to a file as it passes through the stream, like this:

public void removeLine(String lineContent) throws IOException
{
    File file = new File("myFile.txt");
    File temp = new File("_temp_");
    PrintWriter out = new PrintWriter(new FileWriter(temp));
    Files.lines(file.toPath())
        .filter(line -> !line.contains(lineContent))
        .forEach(out::println);
    out.flush();
    out.close();
    temp.renameTo(file);
}

Not much has been changed in this example. Basically, instead of using collect to gather the file contents into memory, we use forEach so that each line that makes it through the filter gets sent to the PrintWriter to be written out to the file immediately and not stored. We have to save it to a temporary file, because we can't overwrite the existing file at the same time as we are still reading from it, so then at the end, we rename the temp file to replace the existing file.

Thats work for me:

var jsScripts = [];

jsScripts.push("/js/script1.js" );
jsScripts.push("/js/script2.js" );
jsScripts.push("/js/script3.js" );

$(jsScripts).each(function( index, value ) {
    $.holdReady( true );
    $.getScript( value ).done(function(script, status) {
        console.log('Loaded ' + index + ' : ' + value + ' (' + status + ')');                
        $.holdReady( false );
    });
});

You can either create a new Stage, add your controls into it or if you require the POPUP as Dialog box, then you may consider using DialogsFX or ControlsFX(Requires JavaFX8)

For creating a new Stage, you can use the following snippet

@Override
public void start(final Stage primaryStage) {
    Button btn = new Button();
    btn.setText("Open Dialog");
    btn.setOnAction(
        new EventHandler<ActionEvent>() {
            @Override
            public void handle(ActionEvent event) {
                final Stage dialog = new Stage();
                dialog.initModality(Modality.APPLICATION_MODAL);
                dialog.initOwner(primaryStage);
                VBox dialogVbox = new VBox(20);
                dialogVbox.getChildren().add(new Text("This is a Dialog"));
                Scene dialogScene = new Scene(dialogVbox, 300, 200);
                dialog.setScene(dialogScene);
                dialog.show();
            }
         });
    }

If you don't want it to be modal (block other windows), use:

dialog.initModality(Modality.NONE);

For AWS (RHEL):

sudo yum install php56-soap

(56 here is 5.6 PHP version - put your version here).

IN BEGINNING

in fragment, below code(use in onActivityCreated) force to hide keyboard in beginning:

@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    Objects.requireNonNull(getActivity()).getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);
}

DURING FRAGMENT (if need)

and also if you have edittext or sth different needs keyboard, and wanna hide the keyboard when pressing outside the keyboard(in my case I have LinearLayout class in xml), first initialize the layout:

LinearLayout linearLayout;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    
    View view = inflater.inflate(R.layout.<your fragment xml>, container, false);

    linearLayout= view.findViewById(R.id.linearLayout);
    ...
    return view;
}

then, you need to below code(use in onViewCreated):

@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {

    linearLayout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view12) {
            try {
                InputMethodManager inputMethodManager = (InputMethodManager) Objects.requireNonNull(VideoFragment.this.getActivity()).getSystemService(INPUT_METHOD_SERVICE);
                assert inputMethodManager != null;
                inputMethodManager.hideSoftInputFromWindow(VideoFragment.this.getActivity().getCurrentFocus().getWindowToken(), 0);

            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    });

}

As documented in ?legend you do this like so:

plot(1:10,type = "n")
abline(v=seq(1,10,1), col='grey', lty='dotted')
legend(1, 5, "This legend text should not be disturbed by the dotted grey lines,\nbut the plotted dots should still be visible",box.lwd = 0,box.col = "white",bg = "white")
points(1:10,1:10)

Line breaks are achieved with the new line character \n. Making the points still visible is done simply by changing the order of plotting. Remember that plotting in R is like drawing on a piece of paper: each thing you plot will be placed on top of whatever's currently there.

Note that the legend text is cut off because I made the plot dimensions smaller (windows.options does not exist on all R platforms).

Try this: Pick a random name "Lastname, Firstname" and look it up in your phonebook.

1st time: start at the beginning of the book, reading names until you find it, or else find the place where it would have occurred alphabetically and note that it isn't there.

2nd time: Open the book at the half way point and look at the page. Ask yourself, should this person be to the left or to the right. Whichever one it is, take that 1/2 and find the middle of it. Repeat this procedure until you find the page where the entry should be and then either apply the same process to columns, or just search linearly along the names on the page as before.

Time both methods and report back!

[also consider what approach is better if all you have is a list of names, not sorted...]

You can use the below code in the onclick listener of edittext

  TimePickerDialog timePickerDialog = new TimePickerDialog(MainActivity.this,
    new TimePickerDialog.OnTimeSetListener() {

        @Override
        public void onTimeSet(TimePicker view, int hourOfDay,
                              int minute) {

            tv_time.setText(hourOfDay + ":" + minute);
        }
    }, hour, minute, false);
     timePickerDialog.show();

You can see the full code at Android timepicker example

If you are using a file with .dump extension use:

pg_restore -h hostname -d dbname -U username filename.dump

It is possible to download a file using XHR request. You can use angular $http to load the file and then use Blob feature of HTML5 to make browser save it. There is a library that can help you with saving: FileSaver.js.

You could also disable it and at the moment that you make the submit call enable it. I think is the easiest way :)

/<b>(.*?)<\/b>/g

Add g (global) flag after:

/<b>(.*?)<\/b>/g.exec(str)
             //^-----here it is 

However if you want to get all matched elements, then you need something like this:

var str = "<b>Bob</b>, I'm <b>20</b> years old, I like <b>programming</b>.";

var result = str.match(/<b>(.*?)<\/b>/g).map(function(val){
   return val.replace(/<\/?b>/g,'');
});
//result -> ["Bob", "20", "programming"] 

If an element has attributes, regexp will be:

/<b [^>]+>(.*?)<\/b>/g.exec(str)

There is no way you can delete a pull request yourself -- you and the repo owner (and all users with push access to it) can close it, but it will remain in the log. This is part of the philosophy of not denying/hiding what happened during development.

However, if there are critical reasons for deleting it (this is mainly violation of Github Terms of Service), Github support staff will delete it for you.

Whether or not they are willing to delete your PR for you is something you can easily ask them, just drop them an email at [email protected]

UPDATE: Currently Github requires support requests to be created here: https://support.github.com/contact

I had trouble initially (don't know why) but I finally got the following to work with SSMS for SQL Server 2008.

Insert ALT-13 then ALT-10 where desired in your text in a varchar type column (music symbol and square appear and save when you leave the row). Initially you'll get a warning(!) to the left of the row after leaving it. Just re-excecute your SELECT statement. The symbols and warning will disappear but the CR/LF is saved. You must include ALT-13 if you want the text displayed properly in HTML. To quickly determine if this worked, copy the saved text from SSMS to Notepad.

Alternatively, if you can't get this to work, you can do the same thing starting with an nvarchar column. However the symbols will be saved as text so you must convert the column to varchar when you're done to convert the symbols to CR/LFs.

If you want to copy & paste text from another source (another row or table, HTML, Notepad, etc.) and not have your text truncated at the first CR, I found that the solution (Programmer's Notepad) referred to at the following link works with SSMS for SQL Server 2008 using varchar & nvarchar column types.

http://dbaspot.com/sqlserver-programming/409451-how-i-enter-linefeed-when-modifying-text-field-2.html#post1523145

The author of the post (dbaspot) mentions something about creating SQL queries - not sure what he means. Just follow the intructions about Programmer's Notepad and you can copy & paste text to and from SSMS and retain the LFs both ways (using Programmer's Notepad, not Notepad). To have the text display properly in HTML you must add CRs to the text copied to SSMS. The best way to do this is by executing an UPDATE statement using the REPLACE function to add CRs as follows:

UPDATE table_name
SET column_name = REPLACE(column_name , CHAR(10), CHAR(13) + CHAR(10)).

Another approach that works is to create a unique window id and store this value along with the session id in a database table. The window id I often use is integer(now). This value is created when a window is opened and re-assigned to the same window if the window is refreshed, reloaded or submitted to itself. Window values (inputs) are saved in the local table using the link. When a value is required, it is obtained from the database table based on the window id / session id link. While this approach requires a local database, it is virtually foolproof. The use of a database table was easy for me, but I see no reason why local arrays would not work just as well.

You need to start the SQL Server manually. Press

windows + R

type

sqlservermanager12.msc

right click ->Start

Service configuration does not display SQL Server?

You can use following technique to dynamically load JS scripts and libraries on demand in your Angular project.

script.store.ts will contain the path of the script either locally or on a remote server and a name that will be used to load the script dynamically

 interface Scripts {
    name: string;
    src: string;
}  
export const ScriptStore: Scripts[] = [
    {name: 'filepicker', src: 'https://api.filestackapi.com/filestack.js'},
    {name: 'rangeSlider', src: '../../../assets/js/ion.rangeSlider.min.js'}
];

script.service.ts is an injectable service that will handle the loading of script, copy script.service.ts as it is

import {Injectable} from "@angular/core";
import {ScriptStore} from "./script.store";

declare var document: any;

@Injectable()
export class ScriptService {

private scripts: any = {};

constructor() {
    ScriptStore.forEach((script: any) => {
        this.scripts[script.name] = {
            loaded: false,
            src: script.src
        };
    });
}

load(...scripts: string[]) {
    var promises: any[] = [];
    scripts.forEach((script) => promises.push(this.loadScript(script)));
    return Promise.all(promises);
}

loadScript(name: string) {
    return new Promise((resolve, reject) => {
        //resolve if already loaded
        if (this.scripts[name].loaded) {
            resolve({script: name, loaded: true, status: 'Already Loaded'});
        }
        else {
            //load script
            let script = document.createElement('script');
            script.type = 'text/javascript';
            script.src = this.scripts[name].src;
            if (script.readyState) {  //IE
                script.onreadystatechange = () => {
                    if (script.readyState === "loaded" || script.readyState === "complete") {
                        script.onreadystatechange = null;
                        this.scripts[name].loaded = true;
                        resolve({script: name, loaded: true, status: 'Loaded'});
                    }
                };
            } else {  //Others
                script.onload = () => {
                    this.scripts[name].loaded = true;
                    resolve({script: name, loaded: true, status: 'Loaded'});
                };
            }
            script.onerror = (error: any) => resolve({script: name, loaded: false, status: 'Loaded'});
            document.getElementsByTagName('head')[0].appendChild(script);
        }
    });
}

}

Inject this ScriptService wherever you need it and load js libs like this

this.script.load('filepicker', 'rangeSlider').then(data => {
    console.log('script loaded ', data);
}).catch(error => console.log(error));

The JavaDoc explains it very well:

With this option set to a non-zero timeout, a read() call on the InputStream associated with this Socket will block for only this amount of time. If the timeout expires, a java.net.SocketTimeoutException is raised, though the Socket is still valid. The option must be enabled prior to entering the blocking operation to have effect. The timeout must be > 0. A timeout of zero is interpreted as an infinite timeout.

SO_TIMEOUT is the timeout that a read() call will block. If the timeout is reached, a java.net.SocketTimeoutException will be thrown. If you want to block forever put this option to zero (the default value), then the read() call will block until at least 1 byte could be read.

If I understand your question correctly, is it the fact that the required attribute appears to have default behaviour in Safari that's confusing you? If so, see: http://w3c.github.io/html/sec-forms.html#the-required-attribute

required is not a custom attribute in HTML 5. It's defined in the spec, and is used in precisely the way you're presently using it.

EDIT: Well, not precisely. As ms2ger has pointed out, the required attribute is a boolean attribute, and here's what the HTML 5 spec has to say about those:

Note: The values "true" and "false" are not allowed on boolean attributes. To represent a false value, the attribute has to be omitted altogether.

See: http://w3c.github.io/html/infrastructure.html#sec-boolean-attributes

volatile variable is basically used for instant update (flush) in main shared cache line once it updated, so that changes reflected to all worker threads immediately.

in fork(), either child or parent process will execute based on cpu selection.. But in vfork(), surely child will execute first. after child terminated, parent will execute.

i hope this code is work well,try this.

add css file.

.scrollbar {
    height: auto;
    max-height: 180px;
    overflow-x: hidden;

np.random.seed(0) makes the random numbers predictable

>>> numpy.random.seed(0) ; numpy.random.rand(4)
array([ 0.55,  0.72,  0.6 ,  0.54])
>>> numpy.random.seed(0) ; numpy.random.rand(4)
array([ 0.55,  0.72,  0.6 ,  0.54])

With the seed reset (every time), the same set of numbers will appear every time.

If the random seed is not reset, different numbers appear with every invocation:

>>> numpy.random.rand(4)
array([ 0.42,  0.65,  0.44,  0.89])
>>> numpy.random.rand(4)
array([ 0.96,  0.38,  0.79,  0.53])

(pseudo-)random numbers work by starting with a number (the seed), multiplying it by a large number, adding an offset, then taking modulo of that sum. The resulting number is then used as the seed to generate the next "random" number. When you set the seed (every time), it does the same thing every time, giving you the same numbers.

If you want seemingly random numbers, do not set the seed. If you have code that uses random numbers that you want to debug, however, it can be very helpful to set the seed before each run so that the code does the same thing every time you run it.

To get the most random numbers for each run, call numpy.random.seed(). This will cause numpy to set the seed to a random number obtained from /dev/urandom or its Windows analog or, if neither of those is available, it will use the clock.

For more information on using seeds to generate pseudo-random numbers, see wikipedia.

When dialing a number within the country you are in, you still need to dial the national trunk number before the rest of the number. For example, in Australia one would dial:

   0 - trunk prefix
   2 - Area code for New South Wales
6555 - STD code for a specific telephone exchange
1234 - Telephone Exchange specific extension.

For a mobile phone this becomes

   0 -      trunk prefix
   4 -      Area code for a mobile telephone
1234 5678 - Mobile telephone number

Now, when I want to dial via the international trunk, you need to drop the trunk prefix and replace it with the international dialing prefix

   + -      Short hand for the country trunk number
  61 -      Country code for Australia
   4 -      Area code for a mobile telephone
1234 5678 - Mobile telephone number

This is why you often find that the first digit of a telephone number is dropped when dialling internationally, even when using international prefixing to dial within the same country.

So as per the trunk prefix for Germany drop the 0 and add the +49 for Germany's international calling code (for example) giving:

<a href="tel:+496170961709" class="Blondie">_x000D_
    Call me, call me any, anytime_x000D_
      <b>Call me (call me) I'll arrive</b>_x000D_
        When you're ready we can share the wine!_x000D_
</a>

You can use UITableViewRowAction's backgroundColor to set custom image or view. The trick is using UIColor(patternImage:).

Basically the width of UITableViewRowAction area is decided by its title, so you can find a exact length of title(or whitespace) and set the exact size of image with patternImage.

To implement this, I made a UIView's extension method.

func image() -> UIImage {
    UIGraphicsBeginImageContextWithOptions(bounds.size, isOpaque, 0)
    guard let context = UIGraphicsGetCurrentContext() else {
        return UIImage()
    }
    layer.render(in: context)
    let image = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    return image!
}

and to make a string with whitespace and exact length,

fileprivate func whitespaceString(font: UIFont = UIFont.systemFont(ofSize: 15), width: CGFloat) -> String {
    let kPadding: CGFloat = 20
    let mutable = NSMutableString(string: "")
    let attribute = [NSFontAttributeName: font]
    while mutable.size(attributes: attribute).width < width - (2 * kPadding) {
        mutable.append(" ")
    }
    return mutable as String
}

and now, you can create UITableViewRowAction.

func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
    let whitespace = whitespaceString(width: kCellActionWidth)
    let deleteAction = UITableViewRowAction(style: .`default`, title: whitespace) { (action, indexPath) in
        // do whatever you want
    }

    // create a color from patter image and set the color as a background color of action
    let kActionImageSize: CGFloat = 34
    let view = UIView(frame: CGRect(x: 0, y: 0, width: kCellActionWidth, height: kCellHeight))
    view.backgroundColor = UIColor.white
    let imageView = UIImageView(frame: CGRect(x: (kCellActionWidth - kActionImageSize) / 2,
                                              y: (kCellHeight - kActionImageSize) / 2,
                                              width: 34,
                                              height: 34))
    imageView.image = UIImage(named: "x")
    view.addSubview(imageView)
    let image = view.image()

    deleteAction.backgroundColor = UIColor(patternImage: image)

    return [deleteAction]
}

The result will look like this.

Another way to do this is to import custom font which has the image you want to use as a font and use UIButton.appearance. However this will affect other buttons unless you manually set other button's font.

From iOS 11, it will show this message [TableView] Setting a pattern color as backgroundColor of UITableViewRowAction is no longer supported.. Currently it is still working, but it wouldn't work in the future update.

==========================================

For iOS 11+, you can use:

func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
  let deleteAction = UIContextualAction(style: .normal, title: "Delete") { (action, view, completion) in
    // Perform your action here
      completion(true)
  }

  let muteAction = UIContextualAction(style: .normal, title: "Mute") { (action, view, completion) in
    // Perform your action here
    completion(true)
  }

  deleteAction.image = UIImage(named: "icon.png")
  deleteAction.backgroundColor = UIColor.red
  return UISwipeActionsConfiguration(actions: [deleteAction, muteAction])
} 

To disable all mouse click

var event = $(document).click(function(e) {
    e.stopPropagation();
    e.preventDefault();
    e.stopImmediatePropagation();
    return false;
});

// disable right click
$(document).bind('contextmenu', function(e) {
    e.stopPropagation();
    e.preventDefault();
    e.stopImmediatePropagation();
    return false;
});

to enable it again:

$(document).unbind('click');
$(document).unbind('contextmenu');

Each EXE which hosts COM or OLE controls defines it's apartment state. The apartment state is by default STA (and for most programs should be STA).

STA - All OLE controls by necessity must live in a STA. STA means that your COM-object must be always manipulated on the UI thread and cannot be passed to other threads (much like any UI element in MFC). However, your program can still have many threads.

MTA - You can manipulate the COM object on any thread in your program.

If your are referring to two worksheets please use this formula

=COUNTIF(Worksheet2!$A$1:$A$50,Worksheet1cellA1)

In case referring to to more than two worksheets please use this formula

=COUNTIF(Worksheet2!$A$1:$A$50,Worksheet1cellA1)+=COUNTIF
(Worksheet3!$A$1:$A$50,Worksheet1cellA1)+=
               COUNTIF(Worksheet4!$A$1:$A$50,Worksheet1cellA1)

The error message:

merge: remote/master - not something we can merge

is saying that Git doesn't recognize remote/master. This is probably because you don't have a "remote" named "remote". You have a "remote" named "origin".

Think of "remotes" as an alias for the url to your Git server. master is your locally checked-out version of the branch. origin/master is the latest version of master from your Git server that you have fetched (downloaded). A fetch is always safe because it will only update the "origin/x" version of your branches.

So, to get your master branch back in sync, first download the latest content from the git server:

git fetch

Then, perform the merge:

git merge origin/master

...But, perhaps the better approach would be:

git pull origin master

The pull command will do the fetch and merge for you in one step.

eryksun has answered question #1, and I've answered question #3 (the original #4), but now let's answer question #2:

Why does it release 50.5mb in particular - what is the amount that is released based on?

What it's based on is, ultimately, a whole series of coincidences inside Python and malloc that are very hard to predict.

First, depending on how you're measuring memory, you may only be measuring pages actually mapped into memory. In that case, any time a page gets swapped out by the pager, memory will show up as "freed", even though it hasn't been freed.

Or you may be measuring in-use pages, which may or may not count allocated-but-never-touched pages (on systems that optimistically over-allocate, like linux), pages that are allocated but tagged MADV_FREE, etc.

If you really are measuring allocated pages (which is actually not a very useful thing to do, but it seems to be what you're asking about), and pages have really been deallocated, two circumstances in which this can happen: Either you've used brk or equivalent to shrink the data segment (very rare nowadays), or you've used munmap or similar to release a mapped segment. (There's also theoretically a minor variant to the latter, in that there are ways to release part of a mapped segment—e.g., steal it with MAP_FIXED for a MADV_FREE segment that you immediately unmap.)

But most programs don't directly allocate things out of memory pages; they use a malloc-style allocator. When you call free, the allocator can only release pages to the OS if you just happen to be freeing the last live object in a mapping (or in the last N pages of the data segment). There's no way your application can reasonably predict this, or even detect that it happened in advance.

CPython makes this even more complicated—it has a custom 2-level object allocator on top of a custom memory allocator on top of malloc. (See the source comments for a more detailed explanation.) And on top of that, even at the C API level, much less Python, you don't even directly control when the top-level objects are deallocated.

So, when you release an object, how do you know whether it's going to release memory to the OS? Well, first you have to know that you've released the last reference (including any internal references you didn't know about), allowing the GC to deallocate it. (Unlike other implementations, at least CPython will deallocate an object as soon as it's allowed to.) This usually deallocates at least two things at the next level down (e.g., for a string, you're releasing the PyString object, and the string buffer).

If you do deallocate an object, to know whether this causes the next level down to deallocate a block of object storage, you have to know the internal state of the object allocator, as well as how it's implemented. (It obviously can't happen unless you're deallocating the last thing in the block, and even then, it may not happen.)

If you do deallocate a block of object storage, to know whether this causes a free call, you have to know the internal state of the PyMem allocator, as well as how it's implemented. (Again, you have to be deallocating the last in-use block within a malloced region, and even then, it may not happen.)

If you do free a malloced region, to know whether this causes an munmap or equivalent (or brk), you have to know the internal state of the malloc, as well as how it's implemented. And this one, unlike the others, is highly platform-specific. (And again, you generally have to be deallocating the last in-use malloc within an mmap segment, and even then, it may not happen.)

So, if you want to understand why it happened to release exactly 50.5mb, you're going to have to trace it from the bottom up. Why did malloc unmap 50.5mb worth of pages when you did those one or more free calls (for probably a bit more than 50.5mb)? You'd have to read your platform's malloc, and then walk the various tables and lists to see its current state. (On some platforms, it may even make use of system-level information, which is pretty much impossible to capture without making a snapshot of the system to inspect offline, but luckily this isn't usually a problem.) And then you have to do the same thing at the 3 levels above that.

So, the only useful answer to the question is "Because."

Unless you're doing resource-limited (e.g., embedded) development, you have no reason to care about these details.

And if you are doing resource-limited development, knowing these details is useless; you pretty much have to do an end-run around all those levels and specifically mmap the memory you need at the application level (possibly with one simple, well-understood, application-specific zone allocator in between).

You must define the class before creating an instance of the class. Move the invocation of Something to the end of the script.

You can try to put the cart before the horse and invoke procedures before they are defined, but it will be an ugly hack and you will have to roll your own as defined here:

Make function definition in a python file order independent

With 4.0, you will need to manage this yourself by setting the culture for each thread as Alexei describes. But with 4.5, you can define a culture for the appdomain and that is the preferred way to handle this. The relevant apis are CultureInfo.DefaultThreadCurrentCulture and CultureInfo.DefaultThreadCurrentUICulture.

Simple method using System.Data.DataSetExtensions:

table.AsEnumerable().Select(row => new TankReading{
        TankReadingsID = Convert.ToInt32(row["TRReadingsID"]),
        TankID = Convert.ToInt32(row["TankID"]),
        ReadingDateTime = Convert.ToDateTime(row["ReadingDateTime"]),
        ReadingFeet = Convert.ToInt32(row["ReadingFeet"]),
        ReadingInches = Convert.ToInt32(row["ReadingInches"]),
        MaterialNumber = row["MaterialNumber"].ToString(),
        EnteredBy = row["EnteredBy"].ToString(),
        ReadingPounds = Convert.ToDecimal(row["ReadingPounds"]),
        MaterialID = Convert.ToInt32(row["MaterialID"]),
        Submitted = Convert.ToBoolean(row["Submitted"]),
    });

Or:

TankReading TankReadingFromDataRow(DataRow row){
    return new TankReading{
        TankReadingsID = Convert.ToInt32(row["TRReadingsID"]),
        TankID = Convert.ToInt32(row["TankID"]),
        ReadingDateTime = Convert.ToDateTime(row["ReadingDateTime"]),
        ReadingFeet = Convert.ToInt32(row["ReadingFeet"]),
        ReadingInches = Convert.ToInt32(row["ReadingInches"]),
        MaterialNumber = row["MaterialNumber"].ToString(),
        EnteredBy = row["EnteredBy"].ToString(),
        ReadingPounds = Convert.ToDecimal(row["ReadingPounds"]),
        MaterialID = Convert.ToInt32(row["MaterialID"]),
        Submitted = Convert.ToBoolean(row["Submitted"]),
    };
}

// Now you can do this
table.AsEnumerable().Select(row => return TankReadingFromDataRow(row));

Or, better yet, create a TankReading(DataRow r) constructor, then this becomes:

    table.AsEnumerable().Select(row => return new TankReading(row));

This command did the trick from @Aniket Sinha's answer above:

pip install mysqlclient

This should be work for you:(DataTables 1.10.7)

oTable = $('#myTable').dataTable();

$('#myInputTextField').on('keyup change', function(){
  oTable.api().search($(this).val()).draw();
})

or

oTable = $('#myTable').DataTable();

$('#myInputTextField').on('keyup change', function(){
  oTable.search($(this).val()).draw();
})

Simple, use array_intersect() instead:

$result = array_intersect($array1, $array2);

Try this.........

ProgressDialog pd1;
pd1=new ProgressDialog(<current context reference here>);
pd1.setMessage("Loading....");
pd1.setCancelable(false);
pd1.show();

To dismiss....

if(pd1!=null)
 pd1.dismiss(); 

Following worked for me

npm uninstall @angular-devkit/build-angular
npm install @angular-devkit/[email protected]

I have solve this problem by just deleting .gradle folder within my application project..

Delete folder .gradle from your project no need to delete main .gradle folder which is located at C:\Users\<username>

This doesn't seem to work if you're loading the HTML field into a dynamically created element.

$('body').append('<div id="loader"></div>');
$('#loader').load('htmlwithscript.htm');

I look at firebug DOM and there is no script node at all, only the HTML and my CSS node.

Anyone have come across this?

These are questions which, in my opionion, requires different knowledge from different domains.

1. You just can't know in advance "which" tables to build, you have to know the problem you have to solve and design the schema accordingly;
2. This is a mix of database design decision and your database vendor custom capabilities (ie. you should check the documentation of your (r)dbms and eventually learn some "tips & tricks" for scaling), also the configuration of your dbms is crucial for scaling (replication, data partitioning and so on);
3. again, almost every rdbms comes with a particular "dialect" of the SQL language, so if you want efficient queries you have to learn that particular dialect --btw. much probably write elegant query which are also efficient is a big deal: elegance and efficiency are frequently conflicting goals--

That said, maybe you want to read some books, personally I've used this book in my datbase university course (and found a decent one, but I've not read other books in this field, so my advice is to check out for some good books in database design).

By wrapping your comparisons in {} in your first example you are creating ScriptBlocks; so the PowerShell interpreter views it as Where-Object { <ScriptBlock> -and <ScriptBlock> }. Since the -and operator operates on boolean values, PowerShell casts the ScriptBlocks to boolean values. In PowerShell anything that is not empty, zero or null is true. The statement then looks like Where-Object { $true -and $true } which is always true.

Instead of using {}, use parentheses ().

Also you want to use -eq instead of -match since match uses regex and will be true if the pattern is found anywhere in the string (try: 'xlsx' -match 'xls').

Invoke-Command -computername SERVERNAME { 
    Get-ChildItem -path E:\dfsroots\datastore2\public | 
        Where-Object {($_.extension -eq ".xls" -or $_.extension -eq ".xlk") -and ($_.creationtime -ge "06/01/2014")}
}

A better option is to filter the extensions at the Get-ChildItem command.

Invoke-Command -computername SERVERNAME { 
    Get-ChildItem -path E:\dfsroots\datastore2\public\* -Include *.xls, *.xlk | 
        Where-Object {$_.creationtime -ge "06/01/2014"}
}

If you want to get an attribute-by-attribute comparison, and see if and where it fails, you can use the following list comprehension:

[i for i,j in 
 zip([getattr(obj_1, attr) for attr in dir(obj_1)],
     [getattr(obj_2, attr) for attr in dir(obj_2)]) 
 if not i==j]

The extra advantage here is that you can squeeze it one line and enter in the "Evaluate Expression" window when debugging in PyCharm.

WebElement select = driver.findElement(By.id("gender"));
List<WebElement> options = select.findElements(By.tagName("option"));
for (WebElement option : options) {
   if("Germany".equals(option.getText()))
       option.click();   
}

Select the lines that you want to comment and then use Ctrl + ? to comment or uncomment the Python code in the Sublime Text editor.

For single line you can use Shift + #.

string urlParameters = "param1=value1&param2=value2";
string _endPointName = "your url post api";

var httpWebRequest = (HttpWebRequest)WebRequest.Create(_endPointName);

httpWebRequest.ContentType = "application/x-www-form-urlencoded";
httpWebRequest.Method = "POST";
httpWebRequest.Headers["ContentType"] = "application/x-www-form-urlencoded";

System.Net.ServicePointManager.ServerCertificateValidationCallback +=
                                                  (se, cert, chain, sslerror) =>
                                                  {
                                                      return true;
                                                  };


using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
                {
                    streamWriter.Write(urlParameters);
                    streamWriter.Flush();
                    streamWriter.Close();
                }
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();

using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
                {
                    var result = streamReader.ReadToEnd();
                }

Try this

.Bold { font-weight: bold; }

<span> normal text</span> <br>_x000D_
<span class="Bold"> bold text</span> <br>_x000D_
<span> normal text</span> <spanspan>

I'm assuming you mean Linq To Sql

For any CRUD command it's easy to profile the performance of a stored procedure vs. any technology. In this case any difference between the two will be negligible. Try profiling for a 5 (simple types) field object over 100,000 select queries to find out if there's a real difference.

On the other hand the real deal-breaker will be the question on whether you feel comfortable putting your business logic on your database or not, which is an argument against stored procedures.

I use following code for get different result from condition That worked for me.

Select A.column, B.column
FROM TABLE1 A
INNER JOIN
TABLE2 B
ON A.Id = (case when (your condition) then b.Id else (something) END)

The git checkout master of the answer by Woland isn't needed. Instead use the "Checkout to specific local branch" in the "Additional Behaviors" section to set the "Branch name" to master.

The git commit -am "blah" is still needed.

Now you can use the "Git Publisher" under "Post-build Actions" to push the changes. Be sure to specify the "Branches" to push ("Branch to push" = master, "Target remote name" = origin).

"Merge Results" isn't needed.

If you don't want to use a library, this should cover most/all of the same form element types.

function serialize(form) {
  if (!form || !form.elements) return;

  var serial = [], i, j, first;
  var add = function (name, value) {
    serial.push(encodeURIComponent(name) + '=' + encodeURIComponent(value));
  }

  var elems = form.elements;
  for (i = 0; i < elems.length; i += 1, first = false) {
    if (elems[i].name.length > 0) { /* don't include unnamed elements */
      switch (elems[i].type) {
        case 'select-one': first = true;
        case 'select-multiple':
          for (j = 0; j < elems[i].options.length; j += 1)
            if (elems[i].options[j].selected) {
              add(elems[i].name, elems[i].options[j].value);
              if (first) break; /* stop searching for select-one */
            }
          break;
        case 'checkbox':
        case 'radio': if (!elems[i].checked) break; /* else continue */
        default: add(elems[i].name, elems[i].value); break;
      }
    }
  }

  return serial.join('&');
}

You can use datetime.timedelta function:

>>> import datetime
>>> str(datetime.timedelta(seconds=666))
'0:11:06'

Yes there is only one program for Windows PC which have solid GUI and it is essential util for me. I work as a developer and on every computer I've had, first thing install XFind program. It is created in 1997 and till now version is 1.0 and till now works and it is the best. Frequently I need to search some string in a ".cs", ".aspx", ".sct" (Visual FoxPro form code file) or just ".*" and XFind scans all files and show me files and another great thing is that you can look where string is in the file. XFind has also some kind of editor. If it binary file it will show you string finded. Try it and use it forever if you are developer like me.

javac should know where to search for classes. Try this:

javac -cp . p1.java

You shouldn't need to specify classpath. Are you sure the file p1.java exists?

Assuming JQuery ajax, you can add custom headers like -

$.ajax({
  url: url,
  beforeSend: function(xhr) {
    xhr.setRequestHeader("custom_header", "value");
  },
  success: function(data) {
  }
});

Dear olga is clear what the message says. Turn off the custom errors to see the details about this error for fix it, and then you close them back. So add mode="off" as:

<configuration>
    <system.web>
        <customErrors mode="Off"/>
    </system.web>
</configuration>

Relative answer: Deploying website: 500 - Internal server error

By the way: The error message declare that the web.config is not the one you type it here. Maybe you have forget to upload your web.config ? And remember to close the debug flag on the web.config that you use for online pages.
