On which point does HTTPURLConnection try to establish a connection to the given URL?

It's worth clarifying, there's the 'UrlConnection' instance and then there's the underlying Tcp/Ip/SSL socket connection, 2 different concepts. The 'UrlConnection' or 'HttpUrlConnection' instance is synonymous with a single HTTP page request, and is created when you call url.openConnection(). But if you do multiple url.openConnection()'s from the one 'url' instance then if you're lucky, they'll reuse the same Tcp/Ip socket and SSL handshaking stuff...which is good if you're doing lots of page requests to the same server, especially good if you're using SSL where the overhead of establishing the socket is very high.

See: HttpURLConnection implementation

in my case, the DefaultAppPool was stopped, I edited the Advanced Settings and set the value of Identity as LocalSystem, after that I start the DefaultAppPool.

<?php  
    $args = array(
        'post_type'      => 'product',
        'posts_per_page' => 10,
        'product_cat'    => 'hoodies'
    );

    $loop = new WP_Query( $args );

    while ( $loop->have_posts() ) : $loop->the_post();
        global $product;
        echo '<br /><a href="'.get_permalink().'">' . woocommerce_get_product_thumbnail().' '.get_the_title().'</a>';
    endwhile;

    wp_reset_query();
?>

This will list all product thumbnails and names along with their links to product page. change the category name and posts_per_page as per your requirement.

One way of doing this without changing Volley's source code is to check for the response data in the VolleyError and parse it your self.

As of f605da3 commit, Volley throws a ServerError exception that contains the raw network response.

So you can do something similar to this in your error listener:

/* import com.android.volley.toolbox.HttpHeaderParser; */
public void onErrorResponse(VolleyError error) {

    // As of f605da3 the following should work
    NetworkResponse response = error.networkResponse;
    if (error instanceof ServerError && response != null) {
        try {
            String res = new String(response.data,
                       HttpHeaderParser.parseCharset(response.headers, "utf-8"));
            // Now you can use any deserializer to make sense of data
            JSONObject obj = new JSONObject(res);
        } catch (UnsupportedEncodingException e1) {
            // Couldn't properly decode data to string
            e1.printStackTrace();
        } catch (JSONException e2) {
            // returned data is not JSONObject?
            e2.printStackTrace();
        }
    }
}

For future, if Volley changes, one can follow the above approach where you need to check the VolleyError for raw data that has been sent by the server and parse it.

I hope that they implement that TODO mentioned in the source file.

I installed pysocks and monkey patched create_connection in urllib3, like this:

import socks
import socket
socks.setdefaultproxy(socks.PROXY_TYPE_SOCKS4, "127.0.0.1", 1080)

def create_connection(address, timeout=socket._GLOBAL_DEFAULT_TIMEOUT,
                      source_address=None, socket_options=None):
    """Connect to *address* and return the socket object.

    Convenience function.  Connect to *address* (a 2-tuple ``(host,
    port)``) and return the socket object.  Passing the optional
    *timeout* parameter will set the timeout on the socket instance
    before attempting to connect.  If no *timeout* is supplied, the
    global default timeout setting returned by :func:`getdefaulttimeout`
    is used.  If *source_address* is set it must be a tuple of (host, port)

    An host of '' or port 0 tells the OS to use the default.
    """

    host, port = address
    if host.startswith('['):
        host = host.strip('[]')
    err = None
    for res in socket.getaddrinfo(host, port, 0, socket.SOCK_STREAM):
        af, socktype, proto, canonname, sa = res
        sock = None
        try:
            sock = socks.socksocket(af, socktype, proto)

            # If provided, set socket level options before connecting.
            # This is the only addition urllib3 makes to this function.
            urllib3.util.connection._set_socket_options(sock, socket_options)

            if source_address:
                sock.bind(source_address)
            sock.connect(sa)
            return sock

        except socket.error as e:
            err = e
            if sock is not None:
                sock.close()
                sock = None

    if err is not None:
        raise err

    raise socket.error("getaddrinfo returns an empty list")

# monkeypatch
urllib3.util.connection.create_connection = create_connection

As primitives(long) can't be null,It can be converted to wrapper class of that primitive type(ie.Long) and null check can be performed.

If you want to check whether long variable is null,you can convert that into Long and check,

long longValue=null;

if(Long.valueOf(longValue)==null)

Since you are not interested in keeping any data, drop the entire database and create a new one.

Most states are in exactly one time zone (though there are a few exceptions). Most zip codes do not cross state boundaries (though there are a few exceptions).

You could quickly come up with your own list of time zones per zip by combining those facts.

Here's a list of zip code ranges per state, and a list of states per time zone.

You can see the boundaries of zip codes and compare to the timezone map using this link, or Google Earth, to map zips to time zones for the states that are split by a time zone line.

The majority of non-US countries you are dealing with are probably in exactly one time zone (again, there are exceptions). Depending on your needs, you may want to look at where your top-N non-US visitors come from and just lookup their time zone.

There's a simple way of testing low speeds on a real device that seems to have been overlooked. It does require a Mac and an ethernet (or other wired) network connection.

Turn on Wifi sharing on the Mac, turning your computer into a Wifi hotspot, connect your device to this. Use Netlimiter/Charles Proxy or Network Link Conditioner (which you may have already installed) to control the speeds.

For more details and to understand what sort of speeds you should test on check out: http://opensignal.com/blog/2016/02/05/go-slow-how-why-to-test-apps-on-poor-connections/

There is actually a pretty critical difference, insofar as jQuery's Deferreds are meant to be an implementations of Promises (and jQuery3.0 actually tries to bring them into spec).

The key difference between done/then is that

• .done() ALWAYS returns the same Promise/wrapped values it started with, regardless of what you do or what you return.
• .then() always returns a NEW Promise, and you are in charge of controlling what that Promise is based on what the function you passed it returned.

Translated from jQuery into native ES2015 Promises, .done() is sort of like implementing a "tap" structure around a function in a Promise chain, in that it will, if the chain is in the "resolve" state, pass a value to a function... but the result of that function will NOT affect the chain itself.

const doneWrap = fn => x => { fn(x); return x };

Promise.resolve(5)
       .then(doneWrap( x => x + 1))
       .then(doneWrap(console.log.bind(console)));

$.Deferred().resolve(5)
            .done(x => x + 1)
            .done(console.log.bind(console));

Those will both log 5, not 6.

Note that I used done and doneWrap to do logging, not .then. That's because console.log functions don't actually return anything. And what happens if you pass .then a function that doesn't return anything?

Promise.resolve(5)
       .then(doneWrap( x => x + 1))
       .then(console.log.bind(console))
       .then(console.log.bind(console));

That will log:

5

undefined

What happened? When I used .then and passed it a function that didn't return anything, it's implicit result was "undefined"... which of course returned a Promise[undefined] to the next then method, which logged undefined. So the original value we started with was basically lost.

.then() is, at heart, a form of function composition: the result of each step is used as the argument for the function in the next step. That's why .done is best thought of as a "tap"-> it's not actually part of the composition, just something that sneaks a look at the value at a certain step and runs a function at that value, but doesn't actually alter the composition in any way.

This is a pretty fundamental difference, and there's a probably a good reason why native Promises don't have a .done method implemented themselves. We don't eve have to get into why there's no .fail method, because that's even more complicated (namely, .fail/.catch are NOT mirrors of .done/.then -> functions in .catch that return bare values do not "stay" rejected like those passed to .then, they resolve!)

For everyone stumbling upon this post because pandas gets mentioned, you now have the very elegant and straighforward option of directly accessing the secondary_y axis in pandas with ax.right_ax

So paraphrasing the example initially posted, you would write:

table = sql.read_frame(query,connection)

ax = table[[0, 1]].plot(ylim=(0,100), secondary_y=table[1])
ax.set_ylabel('$')
ax.right_ax.set_ylabel('Your second Y-Axis Label goes here!')

(this is already mentioned in these posts as well: 1 2)

Use $ne (for "not equal")

db.collection.find({ "fieldToCheck": { $exists: true, $ne: null } })

div is a block element, which always takes up its own line.

use the span tag instead

DataTable.Select() doesnt give the Rows in the order they were present in the datatable.

If order is important I feel iterating over the datarow collection and forming a List is the right way to go or you could also use overload of DataTable.Select(string filterexpression, string sort).

But this overload may not handle all the ordering (like order by case ...) that SQL provides.

Left Click on chart. «PivotTable Field List» will appear on right. On the right down quarter of PivotTable Field List (S Values), you see the names of the legends. Left Click on the legend name. Left Click on the «Value field settings». At the top there is «Source Name». You can’t change it. Below there is «Custom Name». Change the Custom Name as you wish. Now the legend name on the chart has the new name you gave.

Make sure you are not dynamically applying relative constraints to a view which is not yet there in view hierarchy.

UIView *bottomView = [[UIView alloc] initWithFrame:CGRectZero];
[self.view addSubview:bottomView];

bottomConstraint = [NSLayoutConstraint constraintWithItem:bottomView
                                                attribute:NSLayoutAttributeBottom
                                                relatedBy:NSLayoutRelationEqual
                                                   toItem:self.view
                                                attribute:NSLayoutAttributeBottom
                                               multiplier:1
                                                 constant:0];
bottomConstraint.active = YES;

In above example, bottomView has been made part of view hierarchy before applying relative constraints on it.

From the official docs:

interval The amount of time to delay between automatically cycling an item. If false, carousel will not automatically cycle.

You can either pass this value with javascript or using a data-interval="false" attribute.

The only way is passing the host information as environment when you create a container

run --env <key>=<value>

This solved it for me:

1. Correct the version numbers in package.json, according to the errors;
2. Remove node_modules (rm -rf node_modules);
3. Rerun npm install.

Repeat these steps until there are no more errors.

Try this:

\begin{flalign*}
    &|\vec a| = \sqrt{3^{2}+1^{2}} = \sqrt{10} & \\
    &|\vec b| = \sqrt{1^{2}+23^{2}} = \sqrt{530} &\\ 
    &\cos v = \frac{26}{\sqrt{10} \cdot \sqrt{530}} &\\
    &v = \cos^{-1} \left(\frac{26}{\sqrt{10} \cdot \sqrt{530}}\right) &\\
\end{flalign*}

The & sign separates two columns, so an & at the beginning of a line means that the line starts with a blank column.

try this:

public boolean verifyPwd(){
        if (!(pword.equals(pwdRetypePwd.getText()))){
                  txtaError.setEditable(true);
                  txtaError.setText("*Password didn't match!");
                  txtaError.setForeground(Color.red);
                  txtaError.setEditable(false);
                  return false;
           }
        else {
            return true;
        }

}

if (verifyPwd()==true){
    addNewUser();
}
else {
    // passwords do not match
}

Here's my take on this in case anyone comes across this thread:

This helps protect against non-numerical data destroying either of your final variables that determine lat and lng.

It works by taking in all of your coordinates, parsing them into separate lat and lng elements of an array, then determining the average of each. That average should be the center (and has proven true in my test cases.)

var coords = "50.0160001,3.2840073|50.014458,3.2778274|50.0169713,3.2750587|50.0180745,3.276742|50.0204038,3.2733474|50.0217796,3.2781737|50.0293064,3.2712542|50.0319918,3.2580816|50.0243287,3.2582281|50.0281447,3.2451177|50.0307925,3.2443178|50.0278165,3.2343882|50.0326574,3.2289809|50.0288569,3.2237612|50.0260081,3.2230589|50.0269495,3.2210104|50.0212645,3.2133541|50.0165868,3.1977592|50.0150515,3.1977341|50.0147901,3.1965286|50.0171915,3.1961636|50.0130074,3.1845098|50.0113267,3.1729483|50.0177206,3.1705726|50.0210692,3.1670394|50.0182166,3.158297|50.0207314,3.150927|50.0179787,3.1485753|50.0184944,3.1470782|50.0273077,3.149845|50.024227,3.1340514|50.0244172,3.1236235|50.0270676,3.1244474|50.0260853,3.1184879|50.0344525,3.113806";

var filteredtextCoordinatesArray = coords.split('|');    

    centerLatArray = [];
    centerLngArray = [];


    for (i=0 ; i < filteredtextCoordinatesArray.length ; i++) {

      var centerCoords = filteredtextCoordinatesArray[i]; 
      var centerCoordsArray = centerCoords.split(',');

      if (isNaN(Number(centerCoordsArray[0]))) {      
      } else {
        centerLatArray.push(Number(centerCoordsArray[0]));
      }

      if (isNaN(Number(centerCoordsArray[1]))) {
      } else {
        centerLngArray.push(Number(centerCoordsArray[1]));
      }                    

    }

    var centerLatSum = centerLatArray.reduce(function(a, b) { return a + b; });
    var centerLngSum = centerLngArray.reduce(function(a, b) { return a + b; });

    var centerLat = centerLatSum / filteredtextCoordinatesArray.length ; 
    var centerLng = centerLngSum / filteredtextCoordinatesArray.length ;

The fcntl module is just used for locking the pinning file, so assuming you don't try multiple access, this can be an acceptable workaround. Place this module in your sys.path, and it should just work as the official fcntl module.

Try using this module for development/testing purposes only in windows.

def fcntl(fd, op, arg=0):
    return 0

def ioctl(fd, op, arg=0, mutable_flag=True):
    if mutable_flag:
        return 0
    else:
        return ""

def flock(fd, op):
    return

def lockf(fd, operation, length=0, start=0, whence=0):
    return

You said you didn't want to use a translucent Activity, but that seems to be the best way to do this:

1. In your Manifest, set the Activity theme to Theme.Translucent.NoTitleBar.
2. Don't bother with a layout for your Activity, and don't call setContentView().
3. In your Activity's onCreate(), start your Service with startService().
4. Exit the Activity with finish() once you've started the Service.

In other words, your Activity doesn't have to be visible; it can simply make sure your Service is running and then exit, which sounds like what you want.

I would highly recommend showing at least a Toast notification indicating to the user that you are launching the Service, or that it is already running. It is very bad user experience to have a launcher icon that appears to do nothing when you press it.

Well, first, you need to actually define a function before you can run it (and it doesn't need to be called main). For instance:

class Example(object):
    def run(self):
        print "Hello, world!"

if __name__ == '__main__':
    Example().run()

You don't need to use a class, though - if all you want to do is run some code, just put it inside a function and call the function, or just put it in the if block:

def main():
    print "Hello, world!"

if __name__ == '__main__':
    main()

or

if __name__ == '__main__':
    print "Hello, world!"

You need %in% instead of ==:

library(dplyr)
target <- c("Tom", "Lynn")
filter(dat, name %in% target)  # equivalently, dat %>% filter(name %in% target)

Produces

  days name
1   88 Lynn
2   11  Tom
3    1  Tom
4  222 Lynn
5    2 Lynn

To understand why, consider what happens here:

dat$name == target
# [1] FALSE FALSE FALSE FALSE FALSE FALSE FALSE  TRUE

Basically, we're recycling the two length target vector four times to match the length of dat$name. In other words, we are doing:

 Lynn == Tom
  Tom == Lynn
Chris == Tom
 Lisa == Lynn
 ... continue repeating Tom and Lynn until end of data frame

In this case we don't get an error because I suspect your data frame actually has a different number of rows that don't allow recycling, but the sample you provide does (8 rows). If the sample had had an odd number of rows I would have gotten the same error as you. But even when recycling works, this is clearly not what you want. Basically, the statement dat$name == target is equivalent to saying:

return TRUE for every odd value that is equal to "Tom" or every even value that is equal to "Lynn".

It so happens that the last value in your sample data frame is even and equal to "Lynn", hence the one TRUE above.

To contrast, dat$name %in% target says:

for each value in dat$name, check that it exists in target.

Very different. Here is the result:

[1]  TRUE  TRUE FALSE FALSE FALSE  TRUE  TRUE  TRUE

Note your problem has nothing to do with dplyr, just the mis-use of ==.

I couldn't neatly add code in an answer's comment. But I would use @Ben Barkay's answer then add this to the require.uncache function.

    // see https://github.com/joyent/node/issues/8266
    // use in it in @Ben Barkay's require.uncache function or along with it. whatever
    Object.keys(module.constructor._pathCache).forEach(function(cacheKey) {
        if ( cacheKey.indexOf(moduleName) > -1 ) {
            delete module.constructor._pathCache[ cacheKey ];
        }
    }); 

Say you've required a module, then uninstalled it, then reinstalled the same module but used a different version that has a different main script in its package.json, the next require will fail because that main script does not exists because it's cached in Module._pathCache

you need to forward declare the name of the class if you don't want a header:

class ClassTwo;

Important: This only works in some cases, see Als's answer for more information..

This is a very broad question, so I am going to give a broad answer.

1. A query gets suspended when it is requesting access to a resource that is currently not available. This can be a logical resource like a locked row or a physical resource like a memory data page. The query starts running again, once the resource becomes available. 
2. High disk IO means that a lot of data pages need to be accessed to fulfill the request.

That is all that I can tell from the above screenshot. However, if I were to speculate, you probably have an IO subsystem that is too slow to keep up with the demand. This could be caused by missing indexes or an actually too slow disk. Keep in mind, that 15000 reads for a single OLTP query is slightly high but not uncommon.

0 values of basic types ⁽¹⁾⁽²⁾map to false.

Other values map to true.

This convention was established in original C, via its flow control statements; C didn't have a boolean type at the time.

It's a common error to assume that as function return values, false indicates failure. But in particular from main it's false that indicates success. I've seen this done wrong many times, including in the Windows starter code for the D language (when you have folks like Walter Bright and Andrei Alexandrescu getting it wrong, then it's just dang easy to get wrong), hence this heads-up beware beware.

There's no need to cast to bool for built-in types because that conversion is implicit. However, Visual C++ (Microsoft's C++ compiler) has a tendency to issue a performance warning (!) for this, a pure silly-warning. A cast doesn't suffice to shut it up, but a conversion via double negation, i.e. return !!x, works nicely. One can read !! as a “convert to bool” operator, much as --> can be read as “goes to”. For those who are deeply into readability of operator notation. ;-)

^{1) C++14 §4.12/1 “A zero value, null pointer value, or null member pointer value is converted to false; any other value is converted to true. For direct-initialization (8.5), a prvalue of type std::nullptr_t can be converted to a prvalue of type bool; the resulting value is false.”
2) C99 and C11 §6.3.1.2/1 “When any scalar value is converted to _Bool, the result is 0 if the value compares equal to 0; otherwise, the result is 1.”}

For this you have to set AUTO_INCREMENT value

ALTER TABLE tablename AUTO_INCREMENT = <INITIAL_VALUE>

Example

ALTER TABLE tablename AUTO_INCREMENT = 101

If you want to return more than 1 value use this:

DECLARE @sqlstatement2      NVARCHAR(MAX);
DECLARE @retText            NVARCHAR(MAX);  
DECLARE @ParmDefinition     NVARCHAR(MAX);
DECLARE @retIndex           INT = 0;

SELECT @sqlstatement = 'SELECT @retIndexOUT=column1 @retTextOUT=column2 FROM XXX WHERE bla bla';

SET @ParmDefinition = N'@retIndexOUT INT OUTPUT, @retTextOUT NVARCHAR(MAX) OUTPUT';

exec sp_executesql @sqlstatement, @ParmDefinition, @retIndexOUT=@retIndex OUTPUT, @retTextOUT=@retText OUTPUT;

returned values are in @retIndex and @retText

This doesn't seem to work in Mac Excel 2016. After a bit of digging, it looks like the key combination for entering the array formula has changed from ?+RETURN to CTRL+SHIFT+RETURN.

Using the TreeMap you can sort the map.

Map<String, String> map = new HashMap<>();        
Map<String, String> treeMap = new TreeMap<>(map);
for (String str : treeMap.keySet()) {
    System.out.println(str);
}

I had the same problem yesterday but I did it in a very clean way which works for both client side and server side validation.

Condition: Based on the value of other property in the model, you want to make another property required. Here is the code

public class RequiredIfAttribute : RequiredAttribute
{
    private String PropertyName { get; set; }
    private Object DesiredValue { get; set; }

    public RequiredIfAttribute(String propertyName, Object desiredvalue)
    {
        PropertyName = propertyName;
        DesiredValue = desiredvalue;
    }

    protected override ValidationResult IsValid(object value, ValidationContext context)
    {
        Object instance = context.ObjectInstance;
        Type type = instance.GetType();
        Object proprtyvalue = type.GetProperty(PropertyName).GetValue(instance, null);
        if (proprtyvalue.ToString() == DesiredValue.ToString())
        {
            ValidationResult result = base.IsValid(value, context);
            return result;
        }
        return ValidationResult.Success;
    }
}

Here PropertyName is the property on which you want to make your condition DesiredValue is the particular value of the PropertyName (property) for which your other property has to be validated for required

Say you have the following

public class User
{
    public UserType UserType { get; set; }

    [RequiredIf("UserType", UserType.Admin, ErrorMessageResourceName = "PasswordRequired", ErrorMessageResourceType = typeof(ResourceString))]
    public string Password
    {
        get;
        set;
    }
}

At last but not the least , register adapter for your attribute so that it can do client side validation (I put it in global.asax, Application_Start)

 DataAnnotationsModelValidatorProvider.RegisterAdapter(typeof(RequiredIfAttribute),typeof(RequiredAttributeAdapter));

Make sure this is NOT checked :

[ ] Tools | Options | Text Editor | C/C++ | Formatting | Automatic Indentation On Tab

Let me know if this helped!

Edit 2018-02-06: revision based on this comment

Edit: forgot to mention that this works on Python 2.7.x

There's multiprocesing.pool, and the following sample illustrates how to use one of them:

from multiprocessing.pool import ThreadPool as Pool
# from multiprocessing import Pool

pool_size = 5  # your "parallelness"

# define worker function before a Pool is instantiated
def worker(item):
    try:
        api.my_operation(item)
    except:
        print('error with item')

pool = Pool(pool_size)

for item in items:
    pool.apply_async(worker, (item,))

pool.close()
pool.join()

Now if you indeed identify that your process is CPU bound as @abarnert mentioned, change ThreadPool to the process pool implementation (commented under ThreadPool import). You can find more details here: http://docs.python.org/2/library/multiprocessing.html#using-a-pool-of-workers

I store date in the DB in UTC format but then I show them to the final user in their local timezone

// retrieve
$d = (new \DateTime($val . ' UTC'))->format('U');
return date("Y-m-d H:i:s", $d);

The big point, and the elephant in the room and all that, is that if your application can get hold of the password, then a hacker with access to the box can get hold of it too!

The only way somewhat around this, is that the application asks for the "master password" on the console using Standard Input, and then uses this to decrypt the passwords stored on file. Of course, this completely makes is impossible to have the application start up unattended along with the OS when it boots.

However, even with this level of annoyance, if a hacker manages to get root access (or even just access as the user running your application), he could dump the memory and find the password there.

The thing to ensure, is to not let the entire company have access to the production server (and thereby to the passwords), and make sure that it is impossible to crack this box!

That should help

df.groupby(['NFF', 'ABUSE']).size().unstack().plot(kind='bar', stacked=True)

You could use lookaround instead if all you want to match is whitespace:

(?<=\s|^)\d+(?=\s|$)

In addition to accepted answer, if you're using Entity Migrations for updating database, you should add this line at the beggining of the Up() function in your migration file:

Sql("alter table dbo.CompanyTransactions drop constraint [df__CompanyTr__Creat__0cdae408];");

You can find the constraint name in the error at nuget packet manager console which starts with FK_dbo.

The short answer taken from the announcement of jQuery 3.0 Final Release :

Along with the regular version of jQuery that includes the ajax and effects modules, we’re releasing a “slim” version that excludes these modules. All in all, it excludes ajax, effects, and currently deprecated code.

The file size (gzipped) is about 6k smaller, 23.6k vs 30k.

As of version 0.23, you can directly return a DataFrame using the as_frame argument. For example, loading the iris data set:

from sklearn.datasets import load_iris
iris = load_iris(as_frame=True)
df = iris.data

In my understanding using the provisionally release notes, this works for the breast_cancer, diabetes, digits, iris, linnerud, wine and california_houses data sets.

In the W3 wiki page about structuring HTML5, it says:

<section>: Used to either group different articles into different purposes or subjects, or to define the different sections of a single article.

And then displays an image that I cleaned up:

It's also important to know how to use the <article> tag (from the same W3 link above):

<article> is related to <section>, but is distinctly different. Whereas <section> is for grouping distinct sections of content or functionality, <article> is for containing related individual standalone pieces of content, such as individual blog posts, videos, images or news items. Think of it this way - if you have a number of items of content, each of which would be suitable for reading on their own, and would make sense to syndicate as separate items in an RSS feed, then <article> is suitable for marking them up.

In our example, <section id="main"> contains blog entries. Each blog entry would be suitable for syndicating as an item in an RSS feed, and would make sense when read on its own, out of context, therefore <article> is perfect for them:

<section id="main">
    <article>
      <!-- first blog post -->
    </article>

    <article>
      <!-- second blog post  -->
    </article>

    <article>
      <!-- third blog post -->
    </article>
</section>

Simple huh? Be aware though that you can also nest sections inside articles, where it makes sense to do so. For example, if each one of these blog posts has a consistent structure of distinct sections, then you could put sections inside your articles as well. It could look something like this:

<article>
  <section id="introduction">
  </section>

  <section id="content">
  </section>

  <section id="summary">
  </section>
</article>

JsonLint is good for validating and formatting JSON.

If you are using MariaDB this will work

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "id", updatable = false, nullable = false)
private Long id;

According to this posting by the lead Jenkins developer, Kohsuke Kawaguchi, in 2009, there is no group support for the built-in Jenkins user database. Group support is only usable when integrating Jenkins with LDAP or Active Directory. This appears to be the same in 2012.

However, as Vadim wrote in his answer, you don't need group support for the built-in Jenkins user database, thanks to the Role strategy plug-in.

The closest thing you can get to str.Empty (with the precondition that str is a String) is:

if (!str.length) { ...

JSmooth .exe wrapper

JSmooth is a Java Executable Wrapper. It creates native Windows launchers (standard .exe) for your Java applications. It makes java deployment much smoother and user-friendly, as it is able to find any installed Java VM by itself. When no VM is available, the wrapper can automatically download and install a suitable JVM, or simply display a message or redirect the user to a website.

JSmooth provides a variety of wrappers for your java application, each of them having their own behavior: Choose your flavor!

Download: http://jsmooth.sourceforge.net/

JarToExe 1.8 Jar2Exe is a tool to convert jar files into exe files. Following are the main features as describe on their website:

Can generate “Console”, “Windows GUI”, “Windows Service” three types of .exe files.

Generated .exe files can add program icons and version information. Generated .exe files can encrypt and protect java programs, no temporary files will be generated when the program runs.

Generated .exe files provide system tray icon support. Generated .exe files provide record system event log support. Generated windows service .exe files are able to install/uninstall itself, and support service pause/continue.

• New release of x64 version, can create 64 bits executives. (May 18, 2008)
• Both wizard mode and command line mode supported. (May 18, 2008)
• Download: http://www.brothersoft.com/jartoexe-75019.html

Executor

Package your Java application as a jar, and Executor will turn the jar into a Windows .exe file, indistinguishable from a native application. Simply double-clicking the .exe file will invoke the Java Runtime Environment and launch your application.

In my use case, I wanted to asynchronously retrieve a url, and then follow that url to an external resource in a new window. A directive seemed overkill because I don't need reusability, so I simply did:

<button (click)="navigateToResource()">Navigate</button>

And in my component.ts

navigateToResource(): void {
  this.service.getUrl((result: any) => window.open(result.url));
}

Note:

Routing to a link indirectly like this will likely trigger the browser's popup blocker.

You can simply specify a series of images like this:

\includegraphics<1>{A}
\includegraphics<2>{B}
\includegraphics<3>{C}

This will produce three slides with the images A to C in exactly the same position.

I agree with SLaks, but here you go

   <asp:HyperLink id="hyperlink1" 
                  NavigateUrl="#"
                  Text=""
                  runat="server"/> 

or you can alter the href using

hyperlink1.NavigateUrl = "#"; 
hyperlink1.Text = string.empty;

RPC is an old protocol based on C.It can invoke a remote procedure and make it look like a local call.RPC handles the complexities of passing that remote invocation to the server and getting the result to client.

Java RMI also achieves the same thing but slightly differently.It uses references to remote objects.So, what it does is that it sends a reference to the remote object alongwith the name of the method to invoke.It is better because it results in cleaner code in case of large programs and also distribution of objects over the network enables multiple clients to invoke methods in the server instead of establishing each connection individually.

SELECT * FROM table WHERE field1 NOT LIKE '%$x%'; (Make sure you escape $x properly beforehand to avoid SQL injection)

Edit: NOT IN does something a bit different - your question isn't totally clear so pick which one to use. LIKE 'xxx%' can use an index. LIKE '%xxx' or LIKE '%xxx%' can't.

I like the one-line solution :)

$scriptDir = Split-Path -Path $MyInvocation.MyCommand.Definition -Parent

No external libraries, works on both Python 2.7 and 3.x:

>>> list(set({"a":1, "b": 2}.values()))[0]
1

For aribtrary key just leave out .values()

>>> list(set({"a":1, "b": 2}))[0]
'a'

Another way to resolve this is to use the _token field in ajax data and set the value of {{csrf_token()}} in blade. Here is a working code that I just tried at my end.

$.ajax({
    type: "POST",
    url: '/your_url',
    data: { somefield: "Some field value", _token: '{{csrf_token()}}' },
    success: function (data) {
       console.log(data);
    },
    error: function (data, textStatus, errorThrown) {
        console.log(data);

    },
});

The 'u' in front of the string values means the string is a Unicode string. Unicode is a way to represent more characters than normal ASCII can manage. The fact that you're seeing the u means you're on Python 2 - strings are Unicode by default on Python 3, but on Python 2, the u in front distinguishes Unicode strings. The rest of this answer will focus on Python 2.

You can create a Unicode string multiple ways:

>>> u'foo'
u'foo'
>>> unicode('foo') # Python 2 only
u'foo'

But the real reason is to represent something like this (translation here):

>>> val = u'???????????? ? ?????????????'
>>> val
u'\u041e\u0437\u043d\u0430\u043a\u043e\u043c\u044c\u0442\u0435\u0441\u044c \u0441 \u0434\u043e\u043a\u0443\u043c\u0435\u043d\u0442\u0430\u0446\u0438\u0435\u0439'
>>> print val
???????????? ? ?????????????

For the most part, Unicode and non-Unicode strings are interoperable on Python 2.

There are other symbols you will see, such as the "raw" symbol r for telling a string not to interpret backslashes. This is extremely useful for writing regular expressions.

>>> 'foo\"'
'foo"'
>>> r'foo\"'
'foo\\"'

Unicode and non-Unicode strings can be equal on Python 2:

>>> bird1 = unicode('unladen swallow')
>>> bird2 = 'unladen swallow'
>>> bird1 == bird2
True

but not on Python 3:

>>> x = u'asdf' # Python 3
>>> y = b'asdf' # b indicates bytestring
>>> x == y
False

Remove :

npm uninstall -g angular-cli

Reinstall (with yarn)

# npm install --global yarn
yarn global add @angular/cli@latest
ng set --global packageManager=yarn  # This will help ng-cli to use yarn

Reinstall (with npm)

npm install --global @angular/cli@latest

Another way is to not use global install, and add /node_modules/.bin folder in the PATH, or use npm scripts. It will be softer to upgrade.

You didn't stage the results of your finder move. I believe if you did the move via Finder and then did git add css/mobile.css ; git rm css/iphone.css, git would compute the hash of the new file and only then realize that the hashes of the files match (and thus it's a rename).

I realize this is quite late, but I needed something like this so I whipped up a quick and dirty method to do this.

    NSUInteger height = CGImageGetHeight(imageRef);
    CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();

    UInt8 * m_PixelBuf = malloc(sizeof(UInt8) * height * width * 4);

    NSUInteger bytesPerPixel = 4;
    NSUInteger bytesPerRow = bytesPerPixel * width;
    NSUInteger bitsPerComponent = 8;
    CGContextRef context = CGBitmapContextCreate(m_PixelBuf, width, height,

    CGContextDrawImage(context, CGRectMake(0, 0, width, height), imageRef);
    CGContextRelease(context);

    int length = height * width * 4;
    for (int i=0; i<length; i+=4)
    {

getYear is no longer used and has been replaced by the getFullYear method.

The getYear method returns the year minus 1900; thus:

• For years greater than or equal to 2000, the value returned by getYear is 100 or greater. For example, if the year is 2026, getYear returns 126.
• For years between and including 1900 and 1999, the value returned by getYear is between 0 and 99. For example, if the year is 1976, getYear returns 76.
• For years less than 1900, the value returned by getYear is less than 0. For example, if the year is 1800, getYear returns -100.
• To take into account years before and after 2000, you should use getFullYear instead of getYear so that the year is specified in full.

Here is a concise code. It does relies on a jquery method to find the current window height. On load of iFrame it sets the height of the iframe be the same as the current window. Then to handle resizing of the page, the body tag has an onresize event handler which sets the iframe's height whenever the document is resized.

<html>
<head>
    <title>my I frame is as tall as your page</title>
     <script type="text/javascript" src="http://code.jquery.com/jquery-2.1.1.min.js"></script>
</head>
<body onresize="$('#iframe1').attr('height', $(window).height());" style="margin:0;" >
    <iframe id="iframe1" src="yourpage.html" style="width:100%;"  onload="this.height=$(window).height();"></iframe>

I found 5 main ways to iterate over a Linked List in Java (including the Java 8 way):

1. For Loop
2. Enhanced For Loop
3. While Loop
4. Iterator
5. Collections’s stream() util (Java8)

For loop

LinkedList<String> linkedList = new LinkedList<>();
System.out.println("==> For Loop Example.");
for (int i = 0; i < linkedList.size(); i++) {
    System.out.println(linkedList.get(i));
}

Enhanced for loop

for (String temp : linkedList) {
    System.out.println(temp);
}

While loop

int i = 0;
while (i < linkedList.size()) {
    System.out.println(linkedList.get(i));
    i++;
}

Iterator

Iterator<String> iterator = linkedList.iterator();
while (iterator.hasNext()) {
    System.out.println(iterator.next()); 
}

collection stream() util (Java 8)

linkedList.forEach((temp) -> {
    System.out.println(temp);
});

One thing should be pointed out is that the running time of For Loop or While Loop is O(n square) because get(i) operation takes O(n) time(see this for details). The other 3 ways take linear time and performs better.

To complete Sunit's answer, you can use a selector, not to the text string but to the textColorHint. You must add this attribute on your editText:

android:textColorHint="@color/text_hint_selector"

And your text_hint_selector should be:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" android:color="@android:color/transparent" />
    <item android:color="@color/hint_color" />
</selector>

For the sake of completion, what you describe as "position of points around a central point(assuming they're all equidistant from the center)" is nothing but "Polar Coordinates". And you are asking for way to Convert between polar and Cartesian coordinates which is given as x = r*cos(t), y = r*sin(t).

From the npm docs:

Android 5.0 Lollipop introduced Material Design theme which automatically colors the status bar based on the colorPrimaryDark value of the theme.

This is supported on device pre-lollipop thanks to the library support-v7-appcompat starting from version 21. Blogpost about support appcompat v21 from Chris Banes

The manner I have used before is to use a wild color (a color no one in their right mind would use) for the BackColor and then set the transparency key to that.

this.BackColor = Color.LimeGreen;
this.TransparencyKey = Color.LimeGreen;

Quick Answer

Use index_col=False instead of index_col=None when you have delimiters at the end of each line to turn off index column inference and discard the last column.

More Detail

After looking at the data, there is a comma at the end of each line. And this quote (the documentation has been edited since the time this post was created):

index_col: column number, column name, or list of column numbers/names, to use as the index (row labels) of the resulting DataFrame. By default, it will number the rows without using any column, unless there is one more data column than there are headers, in which case the first column is taken as the index.

from the documentation shows that pandas believes you have n headers and n+1 data columns and is treating the first column as the index.

EDIT 10/20/2014 - More information

I found another valuable entry that is specifically about trailing limiters and how to simply ignore them:

If a file has one more column of data than the number of column names, the first column will be used as the DataFrame’s row names: ...

Ordinarily, you can achieve this behavior using the index_col option.

There are some exception cases when a file has been prepared with delimiters at the end of each data line, confusing the parser. To explicitly disable the index column inference and discard the last column, pass index_col=False: ...

This is because Oracle internally changes empty string to NULL values. Oracle simply won't let insert an empty string.

On the other hand, SQL Server would let you do what you are trying to achieve.

There are 2 workarounds here:

1. Use another column that states whether the 'description' field is valid or not
2. Use some dummy value for the 'description' field where you want it to store empty string. (i.e. set the field to be 'stackoverflowrocks' assuming your real data will never encounter such a description value)

Both are, of course, stupid workarounds :)

string s = "søme string";
s = Regex.Replace(s, @"[^\u0000-\u007F]+", string.Empty);

You should use datetime object, not str.

>>> from datetime import datetime
>>> cr_date = datetime(2013, 10, 31, 18, 23, 29, 227)
>>> cr_date.strftime('%m/%d/%Y')
'10/31/2013'

To get the datetime object from the string, use datetime.datetime.strptime:

>>> datetime.strptime(cr_date, '%Y-%m-%d %H:%M:%S.%f')
datetime.datetime(2013, 10, 31, 18, 23, 29, 227)
>>> datetime.strptime(cr_date, '%Y-%m-%d %H:%M:%S.%f').strftime('%m/%d/%Y')
'10/31/2013'

Try

var ts = TimeSpan.Parse(stringTime);

With a newer .NET you also have

TimeSpan ts;

if(!TimeSpan.TryParse(stringTime, out ts)){
     // throw exception or whatnot
}
// ts now has a valid format

This is the general idiom for parsing strings in .NET with the first version handling erroneous string by throwing FormatException and the latter letting the Boolean TryParse give you the information directly.

Try

comp.requestFocusInWindow();

DotPeek from JetBrains provides quick and easy way to see msil(anycpu), x86, x64

It is worth to mention how to remove the extension also in parallel with getting the extension:

var name = Path.GetFileNameWithoutExtension(fileFullName); // Get the name only

var extension = Path.GetExtension(fileFullName); // Get the extension only

In addition to @Ceki 's answer, If you are using logback and setup a config file in your project (usually logback.xml), you can define the log to plot the stack trace as well using

<encoder>
    <pattern>%date |%-5level| [%thread] [%file:%line] - %msg%n%ex{full}</pattern> 
</encoder>

the %ex in pattern is what makes the difference

The easiest way would be to delete the plugins folder. Run this command: cordova prepare But, before you run it, you can check each plugin's version that you think would work for your build on Cordova's plugin repository website, and then you should modify the config.xml file, manually. Use upper carrots, "^" in the version field of the universal modeling language file, "config," to indicate that you want the specified plugin to update to the latest version in the future (the next time you run the command.)

There is also the function unit_vector() to normalize vectors in the popular transformations module by Christoph Gohlke:

import transformations as trafo
import numpy as np

data = np.array([[1.0, 1.0, 0.0],
                 [1.0, 1.0, 1.0],
                 [1.0, 2.0, 3.0]])

print(trafo.unit_vector(data, axis=1))

you can use QString::fromAscii()

QByteArray data = entity->getData();
QString s_data = QString::fromAscii(data.data());

with data() returning a char*

for QT5, you should use fromCString() instead, as fromAscii() is deprecated, see https://bugreports.qt-project.org/browse/QTBUG-21872 https://bugreports.qt.io/browse/QTBUG-21872

A version of Otto Nascarella's solution that works in strict mode is:

button.addEventListener('click', function handler() {
      ///this will execute only once
      alert('only once!');
      this.removeEventListener('click', handler);
});

You may also need the following directive to be set before the first "sub_filter" for backend-servers with data compression:

proxy_set_header Accept-Encoding "";

Otherwise it may not work. For your example it will look like:

location /admin/ {
    proxy_pass http://localhost:8080/;
    proxy_set_header Accept-Encoding "";
    sub_filter "http://your_server/" "http://your_server/admin/";
    sub_filter_once off;
}

First off, EC2 and Elastic Compute Cloud are the same thing.

Next, AWS encompasses the range of Web Services that includes EC2 and Elastic Beanstalk. It also includes many others such as S3, RDS, DynamoDB, and all the others.

EC2

EC2 is Amazon's service that allows you to create a server (AWS calls these instances) in the AWS cloud. You pay by the hour and only what you use. You can do whatever you want with this instance as well as launch n number of instances.

Elastic Beanstalk

Elastic Beanstalk is one layer of abstraction away from the EC2 layer. Elastic Beanstalk will setup an "environment" for you that can contain a number of EC2 instances, an optional database, as well as a few other AWS components such as a Elastic Load Balancer, Auto-Scaling Group, Security Group. Then Elastic Beanstalk will manage these items for you whenever you want to update your software running in AWS. Elastic Beanstalk doesn't add any cost on top of these resources that it creates for you. If you have 10 hours of EC2 usage, then all you pay is 10 compute hours.

Running Wordpress

For running Wordpress, it is whatever you are most comfortable with. You could run it straight on a single EC2 instance, you could use a solution from the AWS Marketplace, or you could use Elastic Beanstalk.

What to pick?

In the case that you want to reduce system operations and just focus on the website, then Elastic Beanstalk would be the best choice for that. Elastic Beanstalk supports a PHP stack (as well as others). You can keep your site in version control and easily deploy to your environment whenever you make changes. It will also setup an Autoscaling group which can spawn up more EC2 instances if traffic is growing.

Here's the first result off of Google when searching for "elastic beanstalk wordpress": https://www.otreva.com/blog/deploying-wordpress-amazon-web-services-aws-ec2-rds-via-elasticbeanstalk/

I think you are putting one too many curly brackets. Try this

 @if($user->status=='waiting')
            <td><a href="#" class="viewPopLink btn btn-default1" role="button" data-id="{!! $user->travel_id !!}" data-toggle="modal" data-target="#myModal">Approve/Reject</a> </td>
            @else
            <td>{!! $user->status !!}</td>
        @endif

You need to treat a table valued udf like a table, eg JOIN it

from Employee E JOIN dbo.Splitfn(@Id,',') CSV ON E.Emp_Id = CSV.items 

The subject of the certificate is the entity its public key is associated with (i.e. the "owner" of the certificate).

As RFC 5280 says:

The subject field identifies the entity associated with the public key stored in the subject public key field. The subject name MAY be carried in the subject field and/or the subjectAltName extension.

X.509 certificates have a Subject (Distinguished Name) field and can also have multiple names in the Subject Alternative Name extension.

The Subject DN is made of multiple relative distinguished names (RDNs) (themselves made of attribute assertion values) such as "CN=yourname" or "O=yourorganization".

In the context of the article you're linking to, the subject would be the user/owner of the cert.

I would like to mention the predefined variable CPPFLAGS. It might represent a better fit than CFLAGS or CXXFLAGS, since it is described by the GNU Make manual as:

Extra flags to give to the C preprocessor and programs that use it (the C and Fortran compilers).

Examples of built-in implicit rules that use CPPFLAGS

• n.o is made automatically from n.c with a recipe of the form:
  • $(CC) $(CPPFLAGS) $(CFLAGS) -c
• n.o is made automatically from n.cc, n.cpp, or n.C with a recipe of the form:
  • $(CXX) $(CPPFLAGS) $(CXXFLAGS) -c

One would use the command make CPPFLAGS=-Dvar=123 to define the desired macro.

Here's exactly what the setup looks like.

Edit Configurations > '+' > Application:

Emulation is the process of mimicking the outwardly observable behavior to match an existing target. The internal state of the emulation mechanism does not have to accurately reflect the internal state of the target which it is emulating.

Simulation, on the other hand, involves modeling the underlying state of the target. The end result of a good simulation is that the simulation model will emulate the target which it is simulating.

Ideally, you should be able to look into the simulation and observe properties that you would also see if you looked into the original target. In practice, there may some shortcuts to the simulation for performance reasons -- that is, some internal aspects of the simulation may actually be an emulation.

MAME is an arcade game emulator; Hyperterm is a (not very good) terminal emulator. There's no need to model the arcade machine or a terminal in detail to get the desired emulated behavior.

Flight Simulator is a simulator; SPICE is an electronics simulator. They model as much as possible every detail of the target to represent what the target does in reality.

EDIT: Other responses have pointed out that the goal of an emulation is to able to substitute for the object it is emulating. That's an important point. A simulation's focus is more on the modelling of the internal state of the target -- and the simulation does not necessarily lead to emulation. In particular, a simulation may run far slower than real time. SPICE, for example, cannot substitue for an actual electronics circuit (even if assuming there was some kind of magical device that perfectly interfaces electrical circuits to a SPICE simulation.) A simulation Simulation does not always lead to emulation --

You could use the CSS calc parameter to calculate the height dynamically like so:

.dynamic-height {_x000D_
   color: #000;_x000D_
   font-size: 12px;_x000D_
   margin-top: calc(100% - 10px);_x000D_
   text-align: left;_x000D_
}

<div class='dynamic-height'>_x000D_
    <p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. Aenean massa. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Donec quam felis, ultricies nec, pellentesque eu, pretium quis, sem.</p>_x000D_
</div>

Just make sure put single space before and after "and" Keyword..

If your keys are dynamic I would suggest deserializing directly into a DataTable:

    class SampleData
    {
        [JsonProperty(PropertyName = "items")]
        public System.Data.DataTable Items { get; set; }
    }

    public void DerializeTable()
    {
        const string json = @"{items:["
            + @"{""Name"":""AAA"",""Age"":""22"",""Job"":""PPP""},"
            + @"{""Name"":""BBB"",""Age"":""25"",""Job"":""QQQ""},"
            + @"{""Name"":""CCC"",""Age"":""38"",""Job"":""RRR""}]}";
        var sampleData = JsonConvert.DeserializeObject<SampleData>(json);
        var table = sampleData.Items;

        // write tab delimited table without knowing column names
        var line = string.Empty;
        foreach (DataColumn column in table.Columns)            
            line += column.ColumnName + "\t";                       
        Console.WriteLine(line);

        foreach (DataRow row in table.Rows)
        {
            line = string.Empty;
            foreach (DataColumn column in table.Columns)                
                line += row[column] + "\t";                                   
            Console.WriteLine(line);
        }

        // Name   Age   Job    
        // AAA    22    PPP    
        // BBB    25    QQQ    
        // CCC    38    RRR    
    }

You can determine the DataTable column names and types dynamically once deserialized.

Late to the party: Try this>

base_filename = 'Values.txt'
with open(os.path.join(WorkingFolder, base_filename),'w') as outfile:
    df.to_string(outfile)
#Neatly allocate all columns and rows to a .txt file

We can use the new DataFrameRDD for reading and writing the CSV data. There are few advantages of DataFrameRDD over NormalRDD:

1. DataFrameRDD are bit more faster than NormalRDD since we determine the schema and which helps to optimize a lot on runtime and provide us with significant performance gain.
2. Even if the column shifts in CSV it will automatically take the correct column as we are not hard coding the column number which was present in reading the data as textFile and then splitting it and then using the number of column to get the data.
3. In few lines of code you can read the CSV file directly.

You will be required to have this library: Add it in build.sbt

libraryDependencies += "com.databricks" % "spark-csv_2.10" % "1.2.0"

Spark Scala code for it:

val sc = new SparkContext(conf)
val sqlContext = new SQLContext(sc)
val csvInPath = "/path/to/csv/abc.csv"
val df = sqlContext.read.format("com.databricks.spark.csv").option("header","true").load(csvInPath)
//format is for specifying the type of file you are reading
//header = true indicates that the first line is header in it

To convert to normal RDD by taking some of the columns from it and

val rddData = df.map(x=>Row(x.getAs("colA")))
//Do other RDD operation on it

Saving the RDD to CSV format:

val aDf = sqlContext.createDataFrame(rddData,StructType(Array(StructField("colANew",StringType,true))))
aDF.write.format("com.databricks.spark.csv").option("header","true").save("/csvOutPath/aCSVOp")

Since the header is set to true we will be getting the header name in all the output files.

The issue isn't actually a syntax error, the Hive ParseException is just caused by a reserved keyword in Hive (in this case, end).

The solution: use backticks around the offending column name:

CREATE EXTERNAL TABLE moveProjects (cid string, `end` string, category string)
STORED BY 'org.apache.hadoop.hive.dynamodb.DynamoDBStorageHandler'
TBLPROPERTIES ("dynamodb.table.name" = "Projects",
    "dynamodb.column.mapping" = "cid:cid,end:end,category:category");

With the added backticks around end, the query works as expected.

Reserved words in Amazon Hive (as of February 2013):

IF, HAVING, WHERE, SELECT, UNIQUEJOIN, JOIN, ON, TRANSFORM, MAP, REDUCE, TABLESAMPLE, CAST, FUNCTION, EXTENDED, CASE, WHEN, THEN, ELSE, END, DATABASE, CROSS

In Oracle, (+) denotes the "optional" table in the JOIN. So in your query,

SELECT a.id, b.id, a.col_2, b.col_2, ...
FROM a,b
WHERE a.id=b.id(+)

it's a LEFT OUTER JOIN of table 'b' to table 'a'. It will return all data of table 'a' without losing its data when the other side (optional table 'b') has no data.

The modern standard syntax for the same query would be

SELECT  a.id, b.id, a.col_2, b.col_2, ...
FROM a
LEFT JOIN b ON a.id=b.id

or with a shorthand for a.id=b.id (not supported by all databases):

SELECT  a.id, b.id, a.col_2, b.col_2, ...
FROM a
LEFT JOIN b USING(id)

If you remove (+) then it will be normal inner join query

Older syntax, in both Oracle and other databases:

SELECT  a.id, b.id, a.col_2, b.col_2, ...
FROM a,b
WHERE a.id=b.id

More modern syntax:

SELECT  a.id, b.id, a.col_2, b.col_2, ...
FROM a
INNER JOIN b ON a.id=b.id

Or simply:

SELECT  a.id, b.id, a.col_2, b.col_2, ...
FROM a
JOIN b ON a.id=b.id

It will only return all data where both 'a' & 'b' tables 'id' value is same, means common part.

If you want to make your query a Right Join

This is just the same as a LEFT JOIN, but switches which table is optional.

Old Oracle syntax:

SELECT  a.id, b.id, a.col_2, b.col_2, ...
FROM a,b
WHERE a.id(+)=b.id

Modern standard syntax:

SELECT  a.id, b.id, a.col_2, b.col_2, ...
FROM a
RIGHT JOIN b ON a.id=b.id

function time($block) {
    $sw = [Diagnostics.Stopwatch]::StartNew()
    &$block

Surprisingly, none of answers talk about how it is achieved by hibernate behind the screens.

Lazy loading is a design pattern that is effectively used in hibernate for performance reasons which involves following techniques.

1. Byte code instrumentation:

Enhances the base class definition with hibernate hooks to intercept all the calls to that entity object.

Done either at compile time or run[load] time

1.1 Compile time

• Post compile time operation

• Mostly by maven/ant plugins

1.2 Run time

• If no compile time instrumentation is done, this is created at run time Using libraries like javassist

2. Proxies

The entity object that Hibernate returns are proxy of the real type.

See also: Javassist. What is the main idea and where real use?

I was facing same issue with ffmpeg library after merging two Android projects as one project.

Actually issue was arriving due to two different versions of ffmpeg library but they were loaded with same names in memory. One library was placed in JNiLibs while other was inside another library used as module. I was not able to modify the code of module as it was readonly so I renamed the one used in my own code to ffmpegCamera and loaded it in memory with same name.

System.loadLibrary("ffmpegCamera");

This resolved the issue and now both versions of libraries are loading well as separate name and process id in memory.

Because it is not portable.

is a windows / dos only program, so this your code won't run on linux. Moreover, system is not generally regarded as a very good way to call another program - it is usually better to use CreateProcess or fork or something similar.

innerText is the current correct answer for this. The other answers are outdated and incorrect.

document.getElementById('ShowButton').innerText = 'Show filter';

innerHTML also works, and can be used to insert HTML.

Since the frameborder attribute is only necessary for IE, there is another way to get around the validator. This is a lightweight way that doesn't require Javascript or any DOM manipulation.

<!--[if IE]>
   <iframe src="source" frameborder="0">?</iframe>
<![endif]-->
<!--[if !IE]>-->
   <iframe src="source" style="border:none">?</iframe>
<!-- <![endif]-->

I had an error with an array getting the max and the min so my solution was:

int max = Arrays.stream(arrayWithInts).max().getAsInt();
int min = Arrays.stream(arrayWithInts).min().getAsInt();

To do it on page load:

window.onload = function () {_x000D_
  var input = document.getElementById('myTextInput');_x000D_
  input.focus();_x000D_
  input.select();_x000D_
}

<input id="myTextInput" value="Hello world!" />

Element of index 0 may not exist if the first element has been deleted:

let a = ['a', 'b', 'c'];_x000D_
delete a[0];_x000D_
_x000D_
for (let i in a) {_x000D_
  console.log(i + ' ' + a[i]);_x000D_
}

Better way to get the first element without jQuery:

function first(p) {_x000D_
  for (let i in p) return p[i];_x000D_
}_x000D_
_x000D_
console.log( first(['a', 'b', 'c']) );

If you have security\requestFiltering nodes in your web.config as follows:

<security>
  <requestFiltering>
    <verbs allowUnlisted="false">
      <add verb="GET" allowed="true" />
      <add verb="POST" allowed="true" />
      <add verb="PUT" allowed="true" />
      <add verb="DELETE" allowed="true" />
      <add verb="DEBUG" allowed="true" />          
    </verbs>
  </requestFiltering>

make sure you add this as well

<add verb="OPTIONS" allowed="true" />

It's possible you forgot a sheet1 each time somewhere before the columns.count, or it will count the activesheet columns and not the sheet1's.

Also, shouldn't it be xltoleft instead of xltoright? (Ok it is very late here, but I think I know my right from left) I checked it, you must write xltoleft.

lastColumn = Sheet1.Cells(1, sheet1.Columns.Count).End(xlToleft).Column

I tried on Windows and I was getting same issue after enabling this in PHP installation folder\etc\php.ini:

phpMyadmin is working now!

In Notepad++ v. 6.4.1 is this possibility in:Settings->Preferences->Auto-Completion and there check Enable auto-completion on each input.

maybe I'd go by this.

 SQL = SELECT REPLACE(myColumn, '""', '\'') FROM myTable

I used singlequotes because that's the one that registers string expressions in MySQL, or so I believe.

Hope that helps.

If @Maleki's answer isn't working for you, check and see if you have an .editorconfig file in your project folder.

For example the Angular CLI generates one with a new project that looks like this

# Editor configuration, see http://editorconfig.org
root = true

[*]
charset = utf-8
indent_style = space
indent_size = 2
insert_final_newline = true
trim_trailing_whitespace = true

[*.md]
max_line_length = off
trim_trailing_whitespace = false

Changing the indent_size here is required as it seems it will override anything in your .vscode workspace or user settings.

you could use something like

<select ng-model="myselect">
    <option ng-repeat="o in options" ng-selected="{{o==myselect}}" value="{{o}}">
        {{o}}
    </option>
</select>

using ng-selected you preselect the option in case myselect was prefilled.

I prefer this method over ng-options anyway, as ng-options only works with arrays. ng-repeat also works with json-like objects.

Finally I get rid of internal server error message with the following code. Not sure if there is another way to achieve it.

string uri = "Path.asmx";
string soap = "soap xml string";

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
request.Headers.Add("SOAPAction", "\"http://xxxxxx"");
request.ContentType = "text/xml;charset=\"utf-8\"";
request.Accept = "text/xml";
request.Method = "POST";

using (Stream stm = request.GetRequestStream())
{
    using (StreamWriter stmw = new StreamWriter(stm))
    {
        stmw.Write(soap);
    }
}

using (WebResponse webResponse = request.GetResponse())
{
}

For cookies that I am explicitly setting, I switched to use SimpleCookie provided by Apache Shiro. It does not inherit from javax.servlet.http.Cookie so it takes a bit more juggling to get everything to work correctly however it does provide a property set HttpOnly and it works with Servlet 2.5.

For setting a cookie on a response, rather than doing response.addCookie(cookie) you need to do cookie.saveTo(request, response).

Using new api fetch:

    method: "post",
    headers: { "Content-Type": "application/json" },
    body: dataToSend
})
    .then(resp => {
        if (resp.status === 200) {
            return resp.json()
        } else {
            console.log("Status: " + resp.status)
            return Promise.reject("server")
        }
    })
    .then(dataJson => {
        dataReceived = JSON.parse(dataJson)
    })
    .catch(err => {
        if (err === "server") return
        console.log(err)
    })

console.log(`Received: ${dataReceived}`)                

I also faced problem like this and i set this.

@XmlRootElement(name="yourRootElementName")

No, unlike in a lot of other languages, XSLT variables cannot change their values after they are created. You can however, avoid extraneous code with a technique like this:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>

  <xsl:variable name="mapping">
    <item key="1" v1="A" v2="B" />
    <item key="2" v1="X" v2="Y" />
  </xsl:variable>
  <xsl:variable name="mappingNode"
                select="document('')//xsl:variable[@name = 'mapping']" />

  <xsl:template match="....">
    <xsl:variable name="testVariable" select="'1'" />

    <xsl:variable name="values" select="$mappingNode/item[@key = $testVariable]" />

    <xsl:variable name="variable1" select="$values/@v1" />
    <xsl:variable name="variable2" select="$values/@v2" />
  </xsl:template>
</xsl:stylesheet>

In fact, once you've got the values variable, you may not even need separate variable1 and variable2 variables. You could just use $values/@v1 and $values/@v2 instead.

A smart pointer is an object that acts like a pointer, but additionally provides control on construction, destruction, copying, moving and dereferencing.

One can implement one's own smart pointer, but many libraries also provide smart pointer implementations each with different advantages and drawbacks.

For example, Boost provides the following smart pointer implementations:

• shared_ptr<T> is a pointer to T using a reference count to determine when the object is no longer needed.
• scoped_ptr<T> is a pointer automatically deleted when it goes out of scope. No assignment is possible.
• intrusive_ptr<T> is another reference counting pointer. It provides better performance than shared_ptr, but requires the type T to provide its own reference counting mechanism.
• weak_ptr<T> is a weak pointer, working in conjunction with shared_ptr to avoid circular references.
• shared_array<T> is like shared_ptr, but for arrays of T.
• scoped_array<T> is like scoped_ptr, but for arrays of T.

These are just one linear descriptions of each and can be used as per need, for further detail and examples one can look at the documentation of Boost.

Additionally, the C++ standard library provides three smart pointers; std::unique_ptr for unique ownership, std::shared_ptr for shared ownership and std::weak_ptr. std::auto_ptr existed in C++03 but is now deprecated.

.on() is for jQuery version 1.7 and above. If you have an older version, use this:

$("#SomeId").live("click",function(){
    //do stuff;
});

Since Java 11 you may use that:

public FileReader(String fileName, Charset charset) throws IOException;

As of today, you can read some values from HTML5 data attributes in CSS3 declarations. In CaioToOn's fiddle the CSS code can use the data properties for setting the content.

Unfortunately it is not working for the width and height (tested in Google Chrome 35, Mozilla Firefox 30 & Internet Explorer 11).

But there is a CSS3 attr() Polyfill from Fabrice Weinberg which provides support for data-width and data-height. You can find the GitHub repo to it here: cssattr.js.

I know it's an old question, but if someone is looking here again... see https://python-sounddevice.readthedocs.io/en/0.4.1/index.html .

It has a nice example "Input to Ouput Pass-Through" here https://python-sounddevice.readthedocs.io/en/0.4.1/examples.html#input-to-output-pass-through .

... and a lot of other examples as well ...

The answer of @NeplatnyUdaj is right but consider that Excel want the function name in the set language, in my case German. Then you need to use "DATUM" instead of "DATE":

=(((COLUMN_ID_HERE/60)/60)/24)+DATUM(1970,1,1)

Not tested but should work

 products.sort((a,b)=>a.title.rendered > b.title.rendered)

I just came to this conclusion by trial-and-error: runat="server" is needed to access the elements at run-time on server side. Remove them, recompile and watch what happens.

Sure, you can use JS's foreach.

for (var k in result) {
  something(result[k])
}

You need to call the hasOwnProperty function to check whether the property is actually defined on the object itself (as opposed to its prototype), like this:

for (var key in widthRange) {
    if (key === 'length' || !widthRange.hasOwnProperty(key)) continue;
    var value = widthRange[key];
}

Note that you need a separate check for length.
However, you shouldn't be using an array here at all; you should use a regular object. All Javascript objects function as associative arrays.

For example:

var widthRange = { };  //Or new Object()
widthRange[46] = { sel:46, min:0,  max:52 };
widthRange[66] = { sel:66, min:52, max:70 };
widthRange[90] = { sel:90, min:70, max:94 };

So I found this post and the answers did not help me but i was able to figure out why it gave me the error. I had a

cat > temp.txt < EOF
some content
EOF

The issue was that i copied the above code to be in a function and inadvertently tabbed the code. Need to make sure the last EOF is not tabbed.

To count the number of diverse elements having a common type:

li = ['A0','c5','A8','A2','A5','c2','A3','A9']

print sum(1 for el in li if el[0]=='A' and el[1] in '01234')

gives

3 , not 6

Try this one-

if your project maven based, you can also try updating your project maven config by selecting project. Right click project> Maven>Update Project option. it will update your project config.

The correct way of getting computed style is waiting till page is rendered. It can be done in the following manner. Pay attention to timeout on getting auto values.

function getStyleInfo() {
    setTimeout(function() {
        const style = window.getComputedStyle(document.getElementById('__root__'));
        if (style.height == 'auto') {
            getStyleInfo();
        }
        // IF we got here we can do actual business logic staff
        console.log(style.height, style.width);
    }, 100);
};

window.onload=function() { getStyleInfo(); };

If you use just

window.onload=function() {
    var computedStyle = window.getComputedStyle(document.getElementById('__root__'));
}

you can get auto values for width and height because browsers does not render till full load is performed.

IF this is only occurring on deployments, be sure that you have the dependency of the package you are referencing in the .war. For instance, this was working locally on my machine, with debug configurations working fine, but after deploying to Amazon's Elastic Beanstalk , I received this error and noticed one of the dependencies was not bundled in the .war package.

I have used pdf2image. A simple python library that works like charm.

First install poppler on non linux machine. You can just download the zip. Unzip in Program Files and add bin to Machine Path.

After that you can use pdf2image in python class like this:

from pdf2image import convert_from_path, convert_from_bytes
images_from_path = convert_from_path(
   inputfile,
   output_folder=outputpath,
   grayscale=True, fmt='jpeg')

I am not good with python but was able to make exe of it. Later you may use the exe with file input and output parameter. I have used it in C# and things are working fine.

Image quality is good. OCR works fine.

You need to open the file first. This doesn't work:

json_file = json.load('test.json')

But this works:

f = open('test.json')
json_file = json.load(f)

Usually that problem is that in the last iteration you have an empty object or undefine object. use console.log() inside you cicle to check that this doent happend.

Sometimes a prototype in some place add an extra element.

Probably the best cross browser solution for pdf display on web pages is to use the Mozilla PDF.js project code, it can be run as a node.js service and used as follows

<iframe style="width:100%;height:500px" src="http://www.mysite.co.uk/libs/pdfjs/web/viewer.html?file="http://www.mysite.co.uk/mypdf.pdf"></iframe>

A tutorial on how to use pdf.js can be found at this ejectamenta blog article

Also if you want to do something like ClassB.Run("thing");, make sure the Method Run(); is static or you could call it like this: thing.Run("thing");.

Try (updlock, rowlock)

this may not be accurate but its close enough for me

long size = 0;
object o = new object();
using (Stream s = new MemoryStream()) {
    BinaryFormatter formatter = new BinaryFormatter();
    formatter.Serialize(s, o);
    size = s.Length;
}

I was able to write a general contains function for std::list and std::vector,

template<typename T>
bool contains( const list<T>& container, const T& elt )
{
  return find( container.begin(), container.end(), elt ) != container.end() ;
}

template<typename T>
bool contains( const vector<T>& container, const T& elt )
{
  return find( container.begin(), container.end(), elt ) != container.end() ;
}

// use:
if( contains( yourList, itemInList ) ) // then do something

This cleans up the syntax a bit.

But I could not use template template parameter magic to make this work arbitrary stl containers.

// NOT WORKING:
template<template<class> class STLContainer, class T>
bool contains( STLContainer<T> container, T elt )
{
  return find( container.begin(), container.end(), elt ) != container.end() ;
}

Any comments about improving the last answer would be nice.

Fundamentally speaking nothing is wrong with a NULL in a multi-column primary key. But having one has implications the designer likely did not intend, which is why many systems throw an error when you try this.

Consider the case of module/package versions stored as a series of fields:

CREATE TABLE module
  (name        varchar(20) PRIMARY KEY,
   description text DEFAULT '' NOT NULL);

CREATE TABLE version
  (module      varchar(20) REFERENCES module,
   major       integer NOT NULL,
   minor       integer DEFAULT 0 NOT NULL,
   patch       integer DEFAULT 0 NOT NULL,
   release     integer DEFAULT 1 NOT NULL,
   ext         varchar(20),
   notes       text DEFAULT '' NOT NULL,
   PRIMARY KEY (module, major, minor, patch, release, ext));

The first 5 elements of the primary key are regularly defined parts of a release version, but some packages have a customized extension that is usually not an integer (like "rc-foo" or "vanilla" or "beta" or whatever else someone for whom four fields is insufficient might dream up). If a package does not have an extension, then it is NULL in the above model, and no harm would be done by leaving things that way.

But what is a NULL? It is supposed to represent a lack of information, an unknown. That said, perhaps this makes more sense:

CREATE TABLE version
  (module      varchar(20) REFERENCES module,
   major       integer NOT NULL,
   minor       integer DEFAULT 0 NOT NULL,
   patch       integer DEFAULT 0 NOT NULL,
   release     integer DEFAULT 1 NOT NULL,
   ext         varchar(20) DEFAULT '' NOT NULL,
   notes       text DEFAULT '' NOT NULL,
   PRIMARY KEY (module, major, minor, patch, release, ext));

In this version the "ext" part of the tuple is NOT NULL but defaults to an empty string -- which is semantically (and practically) different from a NULL. A NULL is an unknown, whereas an empty string is a deliberate record of "something not being present". In other words, "empty" and "null" are different things. Its the difference between "I don't have a value here" and "I don't know what the value here is."

When you register a package that lacks a version extension you know it lacks an extension, so an empty string is actually the correct value. A NULL would only be correct if you didn't know whether it had an extension or not, or you knew that it did but didn't know what it was. This situation is easier to deal with in systems where string values are the norm, because there is no way to represent an "empty integer" other than inserting 0 or 1, which will wind up being rolled up in any comparisons made later (which has its own implications)*.

Incidentally, both ways are valid in Postgres (since we're discussing "enterprise" RDMBSs), but comparison results can vary quite a bit when you throw a NULL into the mix -- because NULL == "don't know" so all results of a comparison involving a NULL wind up being NULL since you can't know something that is unknown. DANGER! Think carefully about that: this means that NULL comparison results propagate through a series of comparisons. This can be a source of subtle bugs when sorting, comparing, etc.

Postgres assumes you're an adult and can make this decision for yourself. Oracle and DB2 assume you didn't realize you were doing something silly and throw an error. This is usually the right thing, but not always -- you might actually not know and have a NULL in some cases and therefore leaving a row with an unknown element against which meaningful comparisons are impossible is correct behavior.

In any case you should strive to eliminate the number of NULL fields you permit across the entire schema and doubly so when it comes to fields that are part of a primary key. In the vast majority of cases the presence of NULL columns is an indication of un-normalized (as opposed to deliberately de-normalized) schema design and should be thought very hard about before being accepted.

[* NOTE: It is possible to create a custom type that is the union of integers and a "bottom" type that would semantically mean "empty" as opposed to "unknown". Unfortunately this introduces a bit of complexity in comparison operations and usually being truly type correct isn't worth the effort in practice as you shouldn't be permitted many NULL values at all in the first place. That said, it would be wonderful if RDBMSs would include a default BOTTOM type in addition to NULL to prevent the habit of casually conflating the semantics of "no value" with "unknown value".]

That's an old question, I know. But, according to me, it is missing proper answer.

The actual / optimal workflow here would be to incorporate SVN's post-commit hook so it triggers Jenkins job after the actual commit is issued only, not in any other case. This way you avoid unneeded polls on your SCM system.

You may find the following links interesting:

• Jenkins Wiki's post-commit hook description on Subversion Plugin's doc-site. Here you find documented example of the script you are interested in.
• Hook-scripts contrib directory in the source of official Apache Foundation's Subversion's source control repository.
• Similar question on StackOverflow.

In case of my setup in the corp's SVN server, I utilize the following (censored) script as a post-commit hook on the subversion server side:

#!/bin/sh

# POST-COMMIT HOOK

REPOS="$1"
REV="$2"
#TXN_NAME="$3"
LOGFILE=/var/log/xxx/svn/xxx.post-commit.log

MSG=$(svnlook pg --revprop $REPOS svn:log -r$REV)
JENK="http://jenkins.xxx.com:8080/job/xxx/job/xxx/buildWithParameters?token=xxx&username=xxx&cause=xxx+r$REV"
JENKtest="http://jenkins.xxx.com:8080/view/all/job/xxx/job/xxxx/buildWithParameters?token=xxx&username=xxx&cause=xxx+r$REV"

echo post-commit $* >> $LOGFILE 2>&1

# trigger Jenkins job - xxx
svnlook changed $REPOS -r $REV | cut -d' ' -f4 | grep -qP "branches/xxx/xxx/Source"
if test 0 -eq $? ; then
        echo $(date) - $REPOS - $REV: >> $LOGFILE
        svnlook changed $REPOS -r $REV | cut -d' ' -f4 | grep -P "branches/xxx/xxx/Source" >> $LOGFILE 2>&1
        echo logmsg: $MSG >> $LOGFILE 2>&1
        echo curl -qs $JENK >> $LOGFILE 2>&1
        curl -qs $JENK >> $LOGFILE 2>&1
        echo -------- >> $LOGFILE
fi

# trigger Jenkins job - xxxx
svnlook changed $REPOS -r $REV | cut -d' ' -f4 | grep -qP "branches/xxx_TEST"
if test 0 -eq $? ; then
        echo $(date) - $REPOS - $REV: >> $LOGFILE
        svnlook changed $REPOS -r $REV | cut -d' ' -f4 | grep -P "branches/xxx_TEST" >> $LOGFILE 2>&1
        echo logmsg: $MSG >> $LOGFILE 2>&1
        echo curl -qs $JENKtest >> $LOGFILE 2>&1
        curl -qs $JENKtest >> $LOGFILE 2>&1
        echo -------- >> $LOGFILE
fi

In a situation where you are using just spring and not spring mvc, take the following approach.

Place the following in servlet dispatcher

<mvc:annotation-driven />               
<mvc:resources mapping="/css/**" location="/WEB-INF/assets/css/"/>
<mvc:resources mapping="/js/**" location="/WEB-INF/assets/js/"/>

As you will notice /css for stylesheet location, doesn't have to be in /resources folder if you don't have the folder structure required for spring mvc as is the case with a spring application.Same applies to javascript files, fonts if you need them etc.

You can then access the resources as you need them like so

<link rel="stylesheet" href="css/vendor/swiper.min.css" type="text/css" />
<link rel="stylesheet" href="css/styles.css" type="text/css" />

I am sure someone will find this useful as most examples are with spring mvc

I created the following method to check if a ResultSet is empty.

public static boolean resultSetIsEmpty(ResultSet rs){        
    try {
        // We point the last row
        rs.last();
        int rsRows=rs.getRow(); // get last row number

        if (rsRows == 0) {
            return true;
        }

        // It is necessary to back to top the pointer, so we can see all rows in our ResultSet object.
        rs.beforeFirst();
        return false;
    }catch(SQLException ex){            
        return true;
    }
}

It is very important to have the following considerations:

CallableStatement object must be setted to let to ResultSet object go at the end and go back to top.

TYPE_SCROLL_SENSITIVE: ResultSet object can shift at the end and go back to top. Further can catch last changes.

CONCUR_READ_ONLY: We can read the ResultSet object data, but can not updated.

CallableStatement proc = dbconex.prepareCall(select, ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_READ_ONLY);

EXISTS will be faster because once the engine has found a hit, it will quit looking as the condition has proved true.

With IN, it will collect all the results from the sub-query before further processing.

You need the sufficient write permissions on the directory that you are pushing to.

In my case: Windows 2008 server

--device works until your USB device gets unplugged/replugged and then it stops working. You have to use cgroup devices.allow get around it.
You could just use -v /dev:/dev but that's unsafe as it maps all the devices from your host into the container, including raw disk devices and so forth. Basically this allows the container to gain root on the host, which is usually not what you want.
Using the cgroups approach is better in that respect and works on devices that get added after the container as started.

See details here: Accessing USB Devices In Docker without using --privileged

It's a bit hard to paste, but in a nutshell, you need to get the major number for your character device and send that to cgroup:

189 is the major number of /dev/ttyUSB*, which you can get with 'ls -l'. It may be different on your system than on mine:

root@server:~# echo 'c 189:* rwm' > /sys/fs/cgroup/devices/docker/$A*/devices.allow  
(A contains the docker containerID)

Then start your container like this:

docker run -v /dev/bus:/dev/bus:ro -v /dev/serial:/dev/serial:ro -i -t --entrypoint /bin/bash debian:amd64

without doing this, any newly plugged or rebooting device after the container started, will get a new bus ID and will not be allowed access in the container.

It is indeed possible with the following code

 <div href="#" id='a'>
     Hover me
 </div>

<div id='b'>
    Show me
</div>

and css

#a {
  display: block;
}

#a:hover + #b {
  display:block;
}

#b {
  display:none;
  }

Now by hovering on element #a shows element #b.

As a checkbox click = a checkbox change the following will also work:

<CheckBox Click="CheckBox_Click" />

private void CheckBox_Click(object sender, RoutedEventArgs e)
{
    // ... do some stuff
}

It has the additional advantage of working when IsThreeState="True" whereas just handling Checked and Unchecked does not.

SEARCH does not return 0 if there is no match, it returns #VALUE!. So you have to wrap calls to SEARCH with IFERROR.

For example...

=IF(IFERROR(SEARCH("cat", A1), 0), "cat", "none")

or

=IF(IFERROR(SEARCH("cat",A1),0),"cat",IF(IFERROR(SEARCH("22",A1),0),"22","none"))

Here, IFERROR returns the value from SEARCH when it works; the given value of 0 otherwise.

I am surprised that the connection string works for you, because it is missing a semi-colon. Set is only used with objects, so you would not say Set strNaam.

Set cn = CreateObject("ADODB.Connection")
With cn
 .Provider = "Microsoft.Jet.OLEDB.4.0"
  .ConnectionString = "Data Source=D:\test.xls " & _
  ";Extended Properties=""Excel 8.0;HDR=Yes;"""
.Open
End With
strQuery = "SELECT * FROM [Sheet1$E36:E38]"
Set rs = cn.Execute(strQuery)
Do While Not rs.EOF
  For i = 0 To rs.Fields.Count - 1
    Debug.Print rs.Fields(i).Name, rs.Fields(i).Value
    strNaam = rs.Fields(0).Value
  Next
  rs.MoveNext
Loop
rs.Close

There are other ways, depending on what you want to do, such as GetString (GetString Method Description).

I found a solution for my problem while writing my question !

Going into my remote session i tried two key combinations, and it solved the problem on my Desktop : Alt+Enter and Ctrl+Enter (i don't know which one solved the problem though)

I tried to reproduce the problem, but i couldn't... but i'm almost sure it's one of the key combinations described in the question above (since i experienced this problem several times)

So it seems the problem comes from the use of RDP (windows7 and 8)

Update 2017: Problem occurs on Windows 10 aswell.

Another solution to avoid inserting html into data-title is to create independant div with tooltip html content, and refer to this div when creating your tooltip :

<!-- Tooltip link -->
<p><span class="tip" data-tip="my-tip">Hello world</span></p>

<!-- Tooltip content -->
<div id="my-tip" class="tip-content hidden">
    <h2>Tip title</h2>
    <p>This is my tip content</p>
</div>

<script type="text/javascript">
    $(document).ready(function () {
        // Tooltips
        $('.tip').each(function () {
            $(this).tooltip(
            {
                html: true,
                title: $('#' + $(this).data('tip')).html()
            });
        });
    });
</script>

This way you can create complex readable html content, and activate as many tooltips as you want.

pkill -f for whatever reason does not work for me. Whatever that does, it seems very finicky about actually grepping through what ps aux shows me clearly is there.

After an afternoon of swearing I went for putting the following in my start script:

function inside a function or so called nested functions are very usable if you need to do some recursion processes such as looping true multiple layer of array or a file tree without multiple loops or sometimes i use it to avoid creating classes for small jobs which require dividing and isolating functionality among multiple functions. but before you go for nested functions you have to understand that

1. child function will not be available unless the main function is executed
2. Once main function got executed the child functions will be globally available to access
3. if you need to call the main function twice it will try to re define the child function and this will throw a fatal error

so is this mean you cant use nested functions? No, you can with the below workarounds

first method is to block the child function being re declaring into global function stack by using conditional block with function exists, this will prevent the function being declared multiple times into global function stack.

function myfunc($a,$b=5){
    if(!function_exists("child")){
        function child($x,$c){
            return $c+$x;   
        }
    }
    
    try{
        return child($a,$b);
    }catch(Exception $e){
        throw $e;
    }
    
}

//once you have invoke the main function you will be able to call the child function
echo myfunc(10,20)+child(10,10);

and the second method will be limiting the function scope of child to local instead of global, to do that you have to define the function as a Anonymous function and assign it to a local variable, then the function will only be available in local scope and will re declared and invokes every time you call the main function.

function myfunc($a,$b=5){
    $child = function ($x,$c){
        return $c+$x;   
    };
    
    try{
        return $child($a,$b);
    }catch(Exception $e){
        throw $e;
    }
    
}

echo myfunc(10,20);

remember the child will not be available outside the main function or global function stack

For Amazon AWS ECS/ECR, you should manage your environment variables (especially secrets) via a private S3 bucket. See blog post How to Manage Secrets for Amazon EC2 Container Service–Based Applications by Using Amazon S3 and Docker.

You can try these. 1. stringify your JSON Object before calling the server action via ajax 2. deserialize the string in the action then use the data as a dictionary.

Javascript sample below (sending the JSON Object

$.ajax(
   {
       type: 'POST',
       url: 'TheAction',
       data: { 'data': JSON.stringify(theJSONObject) 
   }
})

Action (C#) sample below

[HttpPost]
public JsonResult TheAction(string data) {

       string _jsonObject = data.Replace(@"\", string.Empty);
       var serializer = new System.Web.Script.Serialization.JavaScriptSerializer();           
        Dictionary<string, string> jsonObject = serializer.Deserialize<Dictionary<string, string>>(_jsonObject);


        return Json(new object{status = true});

    }

You still need to explicitly inline your function when doing template specialization (if specialization is in .h file)

Considering that an include statment in php at the most basic level takes the code from a file and pastes it into where you called it and the fact that the manual on include states the following:

When a file is included, the code it contains inherits the variable scope of the line on which the include occurs. Any variables available at that line in the calling file will be available within the called file, from that point forward.

These things make me think that there is a diffrent problem alltogether. Also Option number 3 will never work because you're not redirecting to second.php you're just including it and option number 2 is just a weird work around. The most basic example of the include statment in php is:

vars.php
<?php

$color = 'green';
$fruit = 'apple';

?>

test.php
<?php

echo "A $color $fruit"; // A

include 'vars.php';

echo "A $color $fruit"; // A green apple

?>

Considering that option number one is the closest to this example (even though more complicated then it should be) and it's not working, its making me think that you made a mistake in the include statement (the wrong path relative to the root or a similar issue).

In some scenarios it may be acceptable to use Object.create. The Mozilla reference includes a polyfill if you need back-compatibility or want to roll your own initializer function.

Applied to your example:

Object.create(Person.prototype, {
    'Field1': { value: 'ASD' },
    'Field2': { value: 'QWE' }
});

Useful Scenarios

• Unit Tests
• Inline declaration

In my case I found this useful in unit tests for two reasons:

1. When testing expectations I often want to create a slim object as an expectation
2. Unit test frameworks (like Jasmine) may compare the object prototype (__proto__) and fail the test. For example:

var actual = new MyClass();
actual.field1 = "ASD";
expect({ field1: "ASD" }).toEqual(actual); // fails

The output of the unit test failure will not yield a clue about what is mismatched.

3. In unit tests I can be selective about what browsers I support

Finally, the solution proposed at http://typescript.codeplex.com/workitem/334 does not support inline json-style declaration. For example, the following does not compile:

var o = { 
  m: MyClass: { Field1:"ASD" }
};

I had the same problem. Firefox showed me this error but in chrome everything was OK. then after a google search, i used google cdn for jquery in index.html instead of loading local js file and the problem solved.

ERROR 2005 (HY000): Unknown MySQL server host 'localhost' (0)

modify list of host names for your system:

C:\Windows\System32\drivers\etc\hosts

Make sure that you have the following entry:

127.0.0.1 localhost
In my case that entry was 0.0.0.0 localhost which caussed all problem

(you may need to change modify permission to modify this file)

This performs DNS resolution of host “localhost” to the IP address 127.0.0.1.

If you work with eclipse: Sometimes eclipse supresses the error messages in the ressource files. Solution: Save a temporary ressource that has no errors in the layout folder. Build the project new. Then eclipse shows the correct error in the ressource file. Delete the temporary ressource.

A GridView is a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.

This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.

Whereas a GridLayout is a layout that places its children in a rectangular grid.

It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorial if you want to learn more about GridLayout.

You are calling DoDownloadAsync() but you don't wait it. So your program going to the next line. But there is another problem, Async methods should return Task or Task<T>, if you return nothing and you want your method will be run asyncronously you should define your method like this:

private static async Task DoDownloadAsync()     {         WebClient w = new WebClient();          string txt = await w.DownloadStringTaskAsync("http://www.google.com/");         Debug.WriteLine(txt);     } 

And in Main method you can't await for DoDownloadAsync, because you can't use await keyword in non-async function, and you can't make Main async. So consider this:

var result = DoDownloadAsync();  Debug.WriteLine("DoDownload done"); result.Wait();
