You'd need to use JavaScript to accomplish this, I think.

jQuery:

$(function(){
   $("#innerContainer").hover(
        function(){
            $("#innerContainer").css('border-color','#FFF');
            $("#outerContainer").css('border-color','#FFF');
        },
        function(){
            $("#innerContainer").css('border-color','#000');
            $("#outerContainer").css('border-color','#000');
        }
    );
});

Adjust the values and element id's accordingly :)

It looks like your longs are seconds, and not milliseconds. Date constructor takes time as millis, so

Date d = new Date(timeInSeconds * 1000);

I think the problem is that in the debug visual studio don't use the normal exeName.

it use indtead "NameApplication".host.exe

so the name of the config file is "NameApplication".host.exe.config and not "NameApplication".exe.config

and after the application close - it return to the back app.config

so if you check the wrong file or you check on the wrong time you will see that nothing changed.

public class SplitTest {

    public static String[] split(String text, String delimiter) {
        java.util.List<String> parts = new java.util.ArrayList<String>();

        text += delimiter;

        for (int i = text.indexOf(delimiter), j=0; i != -1;) {
            String temp = text.substring(j,i);
            if(temp.trim().length() != 0) {
                parts.add(temp);
            }
            j = i + delimiter.length();
            i = text.indexOf(delimiter,j);
        }

        return parts.toArray(new String[0]);
    }


    public static void main(String[] args) {
        String str = "004-034556";
        String delimiter = "-";
        String result[] = split(str, delimiter);
        for(String s:result)
            System.out.println(s);
    }
}

In addition to the excellent answers, I would like to emphasize here when to use res.end() and when to use res.send() this was why I originally landed here and I didn't found a solution.

The answer is really simple

res.end() is used to quickly end the response without sending any data.

An example for this would be starting a process on a server

app.get(/start-service, (req, res) => {
   // Some logic here
   exec('./application'); // dummy code
   res.end();
});

If you would like to send data in your response then you should use res.send() instead

app.get(/start-service, (req, res) => {
   res.send('{"age":22}');
});

This SO answer helped me arrive at an answer https://stackoverflow.com/a/30277424/3075340

I use this utility method to set the background tint of a button. It works with pre-lollipop devices:

// Set button background tint programmatically so it is compatible with pre-lollipop devices.
public static void setButtonBackgroundTintAppCompat(Button button, ColorStateList colorStateList){
    Drawable d = button.getBackground();
    if (button instanceof AppCompatButton) {
        // appcompat button replaces tint of its drawable background
        ((AppCompatButton)button).setSupportBackgroundTintList(colorStateList);
    } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        // Lollipop button replaces tint of its drawable background
        // however it is not equal to d.setTintList(c)
        button.setBackgroundTintList(colorStateList);
    } else {
        // this should only happen if
        // * manually creating a Button instead of AppCompatButton
        // * LayoutInflater did not translate a Button to AppCompatButton
        d = DrawableCompat.wrap(d);
        DrawableCompat.setTintList(d, colorStateList);
        button.setBackgroundDrawable(d);
    }

}

How to use in code:

Utility.setButtonBackgroundTintAppCompat(myButton,
ContextCompat.getColorStateList(mContext, R.color.your_custom_color));

This way, you do not have to specify a ColorStateList if you just want to change the background tint and nothing more but maintain the pretty button effects and what not.

According to the release-notes, Java 11 removed the Java EE modules:

java.xml.bind (JAXB) - REMOVED

• Java 8 - OK
• Java 9 - DEPRECATED
• Java 10 - DEPRECATED
• Java 11 - REMOVED

See JEP 320 for more info.

You can fix the issue by using alternate versions of the Java EE technologies. Simply add Maven dependencies that contain the classes you need:

<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-core</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.0</version>
</dependency>

Jakarta EE 8 update (Mar 2020)

Instead of using old JAXB modules you can fix the issue by using Jakarta XML Binding from Jakarta EE 8:

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>2.3.3</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.3</version>
  <scope>runtime</scope>
</dependency>

Jakarta EE 9 update (Nov 2020)

Use latest release of Eclipse Implementation of JAXB 3.0.0:

• Jakarta EE9 API jakarta.xml.bind-api
• compatible implementation jaxb-impl

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>3.0.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>3.0.0</version>
  <scope>runtime</scope>
</dependency>

Note: Jakarta EE 9 adopts new API package namespace jakarta.xml.bind.*, so update import statements:

javax.xml.bind -> jakarta.xml.bind

Maybe you can use matplotlib for this, you can also plot normal images with it. If you call show() the image pops up in a window. Take a look at this:

http://matplotlib.org/users/image_tutorial.html

@Asiddeen bn Muhammad's solution worked for me with a little modification to the css

    .text {
 line-height: 1.5;
  height: 6em; 
white-space: normal;
overflow: hidden;
text-overflow: ellipsis;
display: block;
-webkit-line-clamp: 2;
-webkit-box-orient: vertical;
 }

try this:

.topics tr { line-height: 14px; }

If I understand you correctly, you want the dates of the next 7 days?

You could do the following:

for ($i = 0; $i < 7; $i++)  
  echo date('d/m/y', time() + 86400 * $i);

Check the documentation for the date function for the format you want it in.

// Using LINQ and just referencing p.Employer will lazy load

{
    persons = (
        from p in dbcontext.Persons
        select new Person{
            Name = p.Name,
            Email = p.Email,
            Employer = p.Employer
        }).ToList();
}

The Northwind example cited by Marc Gravell can be rewritten with the City column selected directly by the group statement:

from cust in ctx.Customers
where cust.CustomerID != ""
group cust.City /*here*/ by cust.Country
into grp
select new
{
        Country = grp.Key,
        Count = grp.Distinct().Count()
};

Press Ctrl + Shift + P to open the Command Palette.

You need to use following construction

Please note that you have to add this slash before your file name.

I just had the same problem, and none of the suggestions above worked. Finally I tried unchecking "Atomic soft tabs" in the Editor Settings menu, which worked.

glOrtho describes a transformation that produces a parallel projection. The current matrix (see glMatrixMode) is multiplied by this matrix and the result replaces the current matrix, as if glMultMatrix were called with the following matrix as its argument:

OpenGL documentation (my bold)

The numbers define the locations of the clipping planes (left, right, bottom, top, near and far).

The "normal" projection is a perspective projection that provides the illusion of depth. Wikipedia defines a parallel projection as:

Parallel projections have lines of projection that are parallel both in reality and in the projection plane.

Parallel projection corresponds to a perspective projection with a hypothetical viewpoint—e.g., one where the camera lies an infinite distance away from the object and has an infinite focal length, or "zoom".

This code causes esLint issue: no-prototype-builtins

foo.hasOwnProperty("bar") 

The suggest way here is:

Object.prototype.hasOwnProperty.call(foo, "bar");

If that string comes from a csv file, I would use fgetcsv() (or str_getcsv() if you have PHP V5.3). That will allow you to parse quoted values correctly. If it is not a csv, explode() should be the best choice.

I realize this is late, but there is another way to obtain the URL of the profile image.

To your original url, you can add the parameter redirect=false to obtain the actual URL of the image you'd normally be redirected to.

So, the new request would look like http://graph.facebook.com/517267866/picture?type=large&redirect=false. This will return a JSON object containing the URL of the picture and a boolean is_silhouette (true if the picture is the default Facebook picture).

The picture will be of the size you specified, as well. You can test this additionally by adding dimensions: http://graph.facebook.com/517267866/picture?type=large&redirect=false&width=400&height=400

If you only want to sort only on the 5th field then use -k5,5.

Also, use the -t command line switch to specify the delimiter to tab. Try this:

sort  -k5,5 -r -n -t \t filename

or if the above doesn't work (with the tab) this:

sort  -k5,5 -r -n -t $'\t' filename

The man page for sort states:

-t, --field-separator=SEP use SEP instead of non-blank to blank transition

Finally, this SO question Unix Sort with Tab Delimiter might be helpful.

In your package.json change the devkit builder.

"@angular-devkit/build-angular": "^0.800.1",

to

"@angular-devkit/build-angular": "^0.10.0",

it works for me.
good luck.

You are getting this error because you are using the resultSet before the resultSet.next() method.

To get the count the just use this:

while (rs.next ()) `{ count = rs.getInt (1); }

You will get your result.

Though this question has an answer, I resolved it differently when I had the same issue. I had this issue when I copied folders with the option Create Folder references; then the above solution of adding the folder to the build_path worked. But when the folder was added using the Create groups for any added folder option, the headers were picked up automatically.

As noted before git-rebase(1) is your friend. Assuming the commits are in your master branch, you would do:

git rebase --onto master~3 master~2 master

Before:

1---2---3---4---5  master

After:

1---2---4'---5' master

From git-rebase(1):

A range of commits could also be removed with rebase. If we have the following situation:

E---F---G---H---I---J  topicA

then the command

git rebase --onto topicA~5 topicA~3 topicA

would result in the removal of commits F and G:

E---H'---I'---J'  topicA

This is useful if F and G were flawed in some way, or should not be part of topicA. Note that the argument to --onto and the parameter can be any valid commit-ish.

This may be an old thread but I came across it and figured that I would give a final answer.

The twitch api is json based and to recieve your stream key you need to authorize your app for use with the api. You do so under the connections tab within your profile on twitch.tv itself.. Down the bottom of said tab there is "register your app" or something similar. Register it and you'll get a client-id header for your get requests.

Now you need to attach your Oauthv2 key to your headers or as a param during the query to the following get request.

curl -H 'Accept: application/vnd.twitchtv.v3+json' -H 'Authorization: OAuth ' \ -X GET https://api.twitch.tv/kraken/channel

documentataion here

As you can see in the documentation above, if you've done these two things, your stream key will be made available to you.

As I said - Sorry for the bump but some people do find it hard to read the twitch* api.

Hope that helps somebody in the future.

just use the core https module with the https.request function. Example for a POST request (GET would be similar):

var https = require('https');

var options = {
  host: 'www.google.com',
  port: 443,
  path: '/upload',
  method: 'POST'
};

var req = https.request(options, function(res) {
  console.log('STATUS: ' + res.statusCode);
  console.log('HEADERS: ' + JSON.stringify(res.headers));
  res.setEncoding('utf8');
  res.on('data', function (chunk) {
    console.log('BODY: ' + chunk);
  });
});

req.on('error', function(e) {
  console.log('problem with request: ' + e.message);
});

// write data to request body
req.write('data\n');
req.write('data\n');
req.end();

I really like the solution proposed by @Brian Diggs. However, in my case, I create the line plots in a loop rather than giving them explicitly because I do not know apriori how many plots I will have. When I tried to adapt the @Brian's code I faced some problems with handling the colors correctly. Turned out I needed to modify the aesthetic functions. In case someone has the same problem, here is the code that worked for me.

I used the same data frame as @Brian:

data <- structure(list(month = structure(c(1317452400, 1317538800, 1317625200, 1317711600, 
                                       1317798000, 1317884400, 1317970800, 1318057200, 
                                       1318143600, 1318230000, 1318316400, 1318402800, 
                                       1318489200, 1318575600, 1318662000, 1318748400, 
                                       1318834800, 1318921200, 1319007600, 1319094000), 
                                     class = c("POSIXct", "POSIXt"), tzone = ""),
                   TempMax = c(26.58, 27.78, 27.9, 27.44, 30.9, 30.44, 27.57, 25.71, 
                               25.98, 26.84, 33.58, 30.7, 31.3, 27.18, 26.58, 26.18, 
                               25.19, 24.19, 27.65, 23.92), 
                   TempMed = c(22.88, 22.87, 22.41, 21.63, 22.43, 22.29, 21.89, 20.52,
                                 19.71, 20.73, 23.51, 23.13, 22.95, 21.95, 21.91, 20.72, 
                                 20.45, 19.42, 19.97, 19.61), 
                   TempMin = c(19.34, 19.14, 18.34, 17.49, 16.75, 16.75, 16.88, 16.82, 
                               14.82, 16.01, 16.88, 17.55, 16.75, 17.22, 19.01, 16.95, 
                               17.55, 15.21, 14.22, 16.42)), 
              .Names = c("month", "TempMax", "TempMed", "TempMin"), 
              row.names = c(NA, 20L), class = "data.frame")  

In my case, I generate my.cols and my.names dynamically, but I don't want to make things unnecessarily complicated so I give them explicitly here. These three lines make the ordering of the legend and assigning colors easier.

my.cols <- heat.colors(3, alpha=1)
my.names <- c("TempMin", "TempMed", "TempMax")
names(my.cols) <- my.names

And here is the plot:

p <-  ggplot(data, aes(x = month))

for (i in 1:3){
  p <- p + geom_line(aes_(y = as.name(names(data[i+1])), colour = 
colnames(data[i+1])))#as.character(my.names[i])))
}
p + scale_colour_manual("", 
                        breaks = as.character(my.names),
                        values = my.cols)
p

Another option:

content = dict(k1='foo', k2='nope', k3='bar')
selection = ['k1', 'k3']
filtered = filter(lambda i: i[0] in selection, content.items())

But you get a list (Python 2) or an iterator (Python 3) returned by filter(), not a dict.

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

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

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

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

Basically you need apache / php running.

var inValid = new RegExp('^[_A-z0-9]{1,}$');
var value = "test string";
var k = inValid.test(value);
alert(k);

I was able to have this done via below method

cat ../logs/em2.log.1 |grep -i 192.168.21.15 |awk '{system(`date`); print $1}'

awk has a function called system it enables you to execute any linux bash command within the output of awk.

Since header files from some C libraries use the keyword, the C++ language will have to do something about it.. at the minimum, ignoring the keyword, so we don't have to #define the keyword to a blank macro to suppress the keyword.

Here's a simple solution to recursively overwrite a destination with a source, creating any necessary directories as it goes. This does not handle symlinks, but it would be a simple extension (see answer by @Michael above).

def recursive_overwrite(src, dest, ignore=None):
    if os.path.isdir(src):
        if not os.path.isdir(dest):
            os.makedirs(dest)
        files = os.listdir(src)
        if ignore is not None:
            ignored = ignore(src, files)
        else:
            ignored = set()
        for f in files:
            if f not in ignored:
                recursive_overwrite(os.path.join(src, f), 
                                    os.path.join(dest, f), 
                                    ignore)
    else:
        shutil.copyfile(src, dest)

I'm writing an sp that could be useful for this purpose, basically this sp pivot any table and return a new table pivoted or return just the set of data, this is the way to execute it:

        @sel_cols='column_to_select1,column_to_select2,column_to_select1',@new_table=returned_table_pivoted;

After doing some research, this was happening in Ruby's XMLRPC::Client library - which uses NET::HTTP. The client uses the start() method in NET::HTTP which keeps the connection open for future requests.

This happened precisely at 30 seconds after the last requests - so my assumption here is that the server it's hitting is closing requests after that time. I'm not sure what the default is for NET::HTTP to keep the request open - but I'm about to test with 60 seconds to see if that solves the issue.

You can get a NodeList to iterate through by using getElementsByTagName(), like this:

var lis = document.getElementById("navbar").getElementsByTagName("li");

You can test it out here. This is a NodeList not an array, but it does have a .length and you can iterate over it like an array.

If you want to know the number of visitors (as is titled in the question) and not the number of pageviews, then you'll need to create a custom report.

Terminology

Google Analytics has changed the terminology they use within the reports. Now, visits is named "sessions" and unique visitors is named "users."

User - A unique person who has visited your website. Users may visit your website multiple times, and they will only be counted once.

Session - The number of different times that a visitor came to your site.

Pageviews - The total number of pages that a user has accessed.

Creating a Custom Report

1. To create a custom report, click on the "Customization" item in the left navigation menu, and then click on "Custom Reports".

2. The "Create Custom Report" page will open.
3. Enter a name for your report.
4. In the "Metric Groups" section, enter either "Users" or "Sessions" depending on what information you want to collect (see Terminology, above).
5. In the "Dimension Drilldowns" section, enter "Page".
6. Under "Filters" enter the individual page (exact) or group of pages (using regex) that you would like to see the data for.
7. Save the report and run it.

I think this sample explains the difference between the styles:

james@bodacious-wired:~$cat test.py 
#!/usr/bin/env python

class MyClass:
    element1 = "Hello"

    def __init__(self):
        self.element2 = "World"

obj = MyClass()

print dir(MyClass)
print "--"
print dir(obj)
print "--"
print obj.element1 
print obj.element2
print MyClass.element1 + " " + MyClass.element2
james@bodacious-wired:~$./test.py 
['__doc__', '__init__', '__module__', 'element1']
--
['__doc__', '__init__', '__module__', 'element1', 'element2']
--
Hello World
Hello
Traceback (most recent call last):
  File "./test.py", line 17, in <module>
    print MyClass.element2
AttributeError: class MyClass has no attribute 'element2'

element1 is bound to the class, element2 is bound to an instance of the class.

Note that in both CMake and Autotools you don't always have to set the installation path at configure time. You can use DESTDIR at install time (see also here) instead as in:

make DESTDIR=<installhere> install

See also this question which explains the subtle difference between DESTDIR and PREFIX.

This is intended for staged installs and to allow for storing programs in a different location from where they are run e.g. /etc/alternatives via symbolic links.

However, if your package is relocatable and doesn't need any hard-coded (prefix) paths set via the configure stage you may be able to skip it. So instead of:

cmake -DCMAKE_INSTALL_PREFIX=/usr . && make all install

you would run:

cmake . && make DESTDIR=/usr all install

Note that, as user7498341 points out, this is not appropriate for cases where you really should be using PREFIX.

You can set a property on the form to do this for you if you have a button on the form that closes the form already.

Set the CancelButton property of the form to that button.

Gets or sets the button control that is clicked when the user presses the Esc key.

If you don't have a cancel button then you'll need to add a KeyDown handler and check for the Esc key in that:

private void Form_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Escape)
    {
        this.Close();
    }
}

You will also have to set the KeyPreview property to true.

Gets or sets a value indicating whether the form will receive key events before the event is passed to the control that has focus.

However, as Gargo points out in his answer this will mean that pressing Esc to abort an edit on a control in the dialog will also have the effect of closing the dialog. To avoid that override the ProcessDialogKey method as follows:

protected override bool ProcessDialogKey(Keys keyData)
{
    if (Form.ModifierKeys == Keys.None && keyData == Keys.Escape)
    {
        this.Close();
        return true;
    }
    return base.ProcessDialogKey(keyData);
}

First of all, the fact that the value in the database is a float does not mean that it also fits in a Java float. Float is short for floating point, and floating point types of various precisions exist. Java types float and double are both floating point types of different precision. In a database both are called FLOAT. Since double has a higher precision than float, it probably is a better idea not to cast your value to a float, because you might lose precision.

You might also use BigDecimal, which represent an arbitrary-precision number.

1. Can you run your JNI-using Java application from a console window (launch it from a java command line) to see if there is any report of what may have been detected before the JVM was crashed. When running directly as a Java window application, you may be missing messages that would appear if you ran from a console window instead.

2. Secondly, can you stub your JNI DLL implementation to show that methods in your DLL are being entered from JNI, you are returning properly, etc?

3. Just in case the problem is with an incorrect use of one of the JNI-interface methods from the C++ code, have you verified that some simple JNI examples compile and work with your setup? I'm thinking in particular of using the JNI-interface methods for converting parameters to native C++ formats and turning function results into Java types. It is useful to stub those to make sure that the data conversions are working and you are not going haywire in the COM-like calls into the JNI interface.

4. There are other things to check, but it is hard to suggest any without knowing more about what your native Java methods are and what the JNI implementation of them is trying to do. It is not clear that catching an exception from the C++ code level is related to your problem. (You can use the JNI interface to rethrow the exception as a Java one, but it is not clear from what you provide that this is going to help.)

I came here and looking how to get the number of elements inside a JSONArray. From your question i used length() like that:

JSONArray jar = myjson.getJSONArray("_types");
System.out.println(jar.length());

and it worked as expected. On the other hand jar.size();(as proposed in the other answer) is not working for me.

So for future users searching (like me) how to get the size of a JSONArray, length() works just fine.

As other answers have stated, the -> symbol is used as part of function annotations. In more recent versions of Python >= 3.5, though, it has a defined meaning.

PEP 3107 -- Function Annotations described the specification, defining the grammar changes, the existence of func.__annotations__ in which they are stored and, the fact that it's use case is still open.

In Python 3.5 though, PEP 484 -- Type Hints attaches a single meaning to this: -> is used to indicate the type that the function returns. It also seems like this will be enforced in future versions as described in What about existing uses of annotations:

The fastest conceivable scheme would introduce silent deprecation of non-type-hint annotations in 3.6, full deprecation in 3.7, and declare type hints as the only allowed use of annotations in Python 3.8.

^{(Emphasis mine)}

This hasn't been actually implemented as of 3.6 as far as I can tell so it might get bumped to future versions.

According to this, the example you've supplied:

def f(x) -> 123:
    return x

will be forbidden in the future (and in current versions will be confusing), it would need to be changed to:

def f(x) -> int:
    return x

for it to effectively describe that function f returns an object of type int.

The annotations are not used in any way by Python itself, it pretty much populates and ignores them. It's up to 3rd party libraries to work with them.

Configuration conf = new Configuration();
conf.set("fs.defaultFS", "hdfs://nameNode:9000");
FileSystem fs = FileSystem.get(conf);

set fs.defaultFS works for me! Hadoop-2.8.1

As required in Question::

var string1= "foo/bar/test.html";
  if(string1.contains("/"))
  {
      var string_parts = string1.split("/");
    var result = string_parts[string_parts.length - 1];
    console.log(result);
  }  

and for question asked on url (asked for one occurence of '=' )::
[http://stackoverflow.com/questions/24156535/how-to-split-a-string-after-a-particular-character-in-jquery][1]

var string1= "Hello how are =you";
  if(string1.contains("="))
  {
      var string_parts = string1.split("=");
    var result = string_parts[string_parts.length - 1];
    console.log(result);
  }

You can do Response.redirect("YourPage",false) that will refresh your page and also increase counter.

Usually I override my compareTo() method like this whenever I have to do multilevel sorting.

public int compareTo(Song o) {
    // TODO Auto-generated method stub
    int comp1 = 10000000*(movie.compareTo(o.movie))+1000*(artist.compareTo(o.artist))+songLength;
    int comp2 = 10000000*(o.movie.compareTo(movie))+1000*(o.artist.compareTo(artist))+o.songLength;
    return comp1-comp2;
} 

Here first preference is given to movie name then to artist and lastly to songLength. You just have to make sure that those multipliers are distant enough to not cross each other's boundaries.

Thank you Rob W for your answer.

I have been using this within a Cordova application to avoid having to load the API and so that I can easily control iframes which are loaded dynamically.

I always wanted the ability to be able to extract information from the iframe, such as the state (getPlayerState) and the time (getCurrentTime).

Rob W helped highlight how the API works using postMessage, but of course this only sends information in one direction, from our web page into the iframe. Accessing the getters requires us to listen for messages posted back to us from the iframe.

It took me some time to figure out how to tweak Rob W's answer to activate and listen to the messages returned by the iframe. I basically searched through the source code within the YouTube iframe until I found the code responsible for sending and receiving messages.

The key was changing the 'event' to 'listening', this basically gave access to all the methods which were designed to return values.

Below is my solution, please note that I have switched to 'listening' only when getters are requested, you can tweak the condition to include extra methods.

Note further that you can view all messages sent from the iframe by adding a console.log(e) to the window.onmessage. You will notice that once listening is activated you will receive constant updates which include the current time of the video. Calling getters such as getPlayerState will activate these constant updates but will only send a message involving the video state when the state has changed.

function callPlayer(iframe, func, args) {
    iframe=document.getElementById(iframe);
    var event = "command";
    if(func.indexOf('get')>-1){
        event = "listening";
    }

    if ( iframe&&iframe.src.indexOf('youtube.com/embed') !== -1) {
      iframe.contentWindow.postMessage( JSON.stringify({
          'event': event,
          'func': func,
          'args': args || []
      }), '*');
    }
}
window.onmessage = function(e){
    var data = JSON.parse(e.data);
    data = data.info;
    if(data.currentTime){
        console.log("The current time is "+data.currentTime);
    }
    if(data.playerState){
        console.log("The player state is "+data.playerState);
    }
}

SQLAlchemy is very, very powerful. However it is not thread safe make sure you keep that in mind when working with cherrypy in thread-pool mode.

Customizing FROM address

MESSAGE="SOME MESSAGE"
SUBJECT="SOME SUBJECT"
TOADDR="[email protected]"
FROM="DONOTREPLY"

echo $MESSAGE | mail  -s "$SUBJECT" $TOADDR  -- -f $FROM

I had the same problem and tried all of the mentioned solutions to no avail. through testing i found that making the text selectable was preventing the listener to be called. So by switching it to false, or removing it my listener was called again.

android:textIsSelectable="false"

hope this helps someone who was stuck like me.

Since I found this question not being aware, that mysql always stores time in timestamp fields in UTC but will display (e.g. phpmyadmin) in local time zone I would like to add my findings.

I have an automatically updated last_modified field, defined as:

`last_modified` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP

Looking at it with phpmyadmin, it looks like it is in local time, internally it is UTC

SET time_zone = '+04:00'; // or '+00:00' to display dates in UTC or 'UTC' if time zones are installed.
SELECT last_modified, UNIX_TIMESTAMP(last_modified), from_unixtime(UNIX_TIMESTAMP(last_modified), '%Y-%c-%d %H:%i:%s'), CONVERT_TZ(last_modified,@@session.time_zone,'+00:00') as UTC FROM `table_name`

In any constellation, UNIX_TIMESTAMP and 'as UTC' are always displayed in UTC time.

Run this twice, first without setting the time_zone.

I was having a similar problem with an Eclipse/PyDev project. In this project the root directory of the python code was a sub-directory of the project.

--> MyProject
 + --> src         Root of python code
   + --> module1     A module 
   + --> module2     Another module
 + --> docs
 + --> test

When the project was debugged or run everything was fine as the working directory was set to the correct place. However the PyDev code analysis was failing to find any imports from module1 or module2.

Solution was to edit the project properties -> PyDev - PYTHONPATH section and remove /MyProject from the source folders tab and add /MyProject/src to it instead.

String s1=""; // empty string assigned to s1 , s1 has length 0, it holds a value of no length string

String s2=null; // absolutely nothing, it holds no value, you are not assigning any value to s2

so null is not the same as empty.

hope that helps!!!

I was just going to do this as a comment on the accepted answer but it got too funky (I hate not having line breaks)

ah, so the difference is that in general, Map has certain methods associated with it. but there are different ways or creating a map, such as a HashMap, and these different ways provide unique methods that not all maps have.

Exactly--and you always want to use the most general interface you possibly can. Consider ArrayList vs LinkedList. Huge difference in how you use them, but if you use "List" you can switch between them readily.

In fact, you can replace the right-hand side of the initializer with a more dynamic statement. how about something like this:

List collection;
if(keepSorted)
    collection=new LinkedList();
else
    collection=new ArrayList();

This way if you are going to fill in the collection with an insertion sort, you would use a linked list (an insertion sort into an array list is criminal.) But if you don't need to keep it sorted and are just appending, you use an ArrayList (More efficient for other operations).

This is a pretty big stretch here because collections aren't the best example, but in OO design one of the most important concepts is using the interface facade to access different objects with the exact same code.

Edit responding to comment:

As for your map comment below, Yes using the "Map" interface restricts you to only those methods unless you cast the collection back from Map to HashMap (which COMPLETELY defeats the purpose).

Often what you will do is create an object and fill it in using it's specific type (HashMap), in some kind of "create" or "initialize" method, but that method will return a "Map" that doesn't need to be manipulated as a HashMap any more.

If you ever have to cast by the way, you are probably using the wrong interface or your code isn't structured well enough. Note that it is acceptable to have one section of your code treat it as a "HashMap" while the other treats it as a "Map", but this should flow "down". so that you are never casting.

Also notice the semi-neat aspect of roles indicated by interfaces. A LinkedList makes a good stack or queue, an ArrayList makes a good stack but a horrific queue (again, a remove would cause a shift of the entire list) so LinkedList implements the Queue interface, ArrayList does not.

You also encounter this if you run an Application on a Scheduled Task in Non-Interactive mode.

As soon as you show a Dialog it throws the error:

Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.

You can see its a MessageBox causing the problem in the stack trace:

at System.Windows.Forms.MessageBox.ShowCore(IWin32Window owner, String text, String caption, MessageBoxButtons buttons, MessageBoxIcon icon,  MessageBoxDefaultButton defaultButton, MessageBoxOptions options, Boolean showHelp)  

Solution

If you're running your app on a Scheduled Task send an email instead of showing a Dialog.

The solution is the /Y switch:

xcopy "C:\Users\ADMIN\Desktop\*.*" "D:\Backup\" /K /D /H /Y

yes, it may work in KITKAT.

above KITKAT+ it will go to internal storage:paths like(storage/emulated/0).

please think, how "Xender app" give permission to write in to external sd card.

So, Fortunately in Android 5.0 and later there is a new official way for apps to write to the external SD card. Apps must ask the user to grant write access to a folder on the SD card. They open a system folder chooser dialog. The user need to navigate into that specific folder and select it.

for more details, please refer https://metactrl.com/docs/sdcard-on-lollipop/

This is the logger class that I use. The private Log() method has EventLog.WriteEntry() in it, which is how you actually write to the event log. I'm including all of this code here because it's handy. In addition to logging, this class will also make sure the message isn't too long to write to the event log (it will truncate the message). If the message was too long, you'd get an exception. The caller can also specify the source. If the caller doesn't, this class will get the source. Hope it helps.

By the way, you can get an ObjectDumper from the web. I didn't want to post all that here. I got mine from here: C:\Program Files (x86)\Microsoft Visual Studio 10.0\Samples\1033\CSharpSamples.zip\LinqSamples\ObjectDumper

The question is why does the limitation still exist. Surely modern Windows can increase the side of MAX_PATH to allow longer paths. Why has the limitation not been removed?

• The reason it cannot be removed is that Windows promised it would never change.

Through API contract, Windows has guaranteed all applications that the standard file APIs will never return a path longer than 260 characters.

Consider the following correct code:

WIN32_FIND_DATA findData;

FindFirstFile("C:\Contoso\*", ref findData);

Windows guaranteed my program that it would populate my WIN32_FIND_DATA structure:

WIN32_FIND_DATA {
   DWORD    dwFileAttributes;
   FILETIME ftCreationTime;
   FILETIME ftLastAccessTime;
   FILETIME ftLastWriteTime;
   //...
   TCHAR    cFileName[MAX_PATH];
   //..
}

My application didn't declare the value of the constant MAX_PATH, the Windows API did. My application used that defined value.

My structure is correctly defined, and only allocates 592 bytes total. That means that i am only able to receive a filename that is less than 260 characters. Windows promised me that if i wrote my application correctly, my application would continue to work in the future.

If Windows were to allow filenames longer than 260 characters then my existing application (which used the correct API correctly) would fail.

For anyone calling for Microsoft to change the MAX_PATH constant, they first need to ensure that no existing application fails. For example, i still own and use a Windows application that was written to run on Windows 3.11. It still runs on 64-bit Windows 10. That is what backwards compatibility gets you.

Microsoft did create a way to use the full 32,768 path names; but they had to create a new API contract to do it. For one, you should use the Shell API to enumerate files (as not all files exist on a hard drive or network share).

But they also have to not break existing user applications. The vast majority of applications do not use the shell api for file work. Everyone just calls FindFirstFile/FindNextFile and calls it a day.

A @ViewScoped bean lives exactly as long as a JSF view. It usually starts with a fresh new GET request, or with a navigation action, and will then live as long as the enduser submits any POST form in the view to an action method which returns null or void (and thus navigates back to the same view). Once you refresh the page, or return a non-null string (even an empty string!) navigation outcome, then the view scope will end.

A @RequestScoped bean lives exactly as long a HTTP request. It will thus be garbaged by end of every request and recreated on every new request, hereby losing all changed properties.

A @ViewScoped bean is thus particularly more useful in rich Ajax-enabled views which needs to remember the (changed) view state across Ajax requests. A @RequestScoped one would be recreated on every Ajax request and thus fail to remember all changed view state. Note that a @ViewScoped bean does not share any data among different browser tabs/windows in the same session like as a @SessionScoped bean. Every view has its own unique @ViewScoped bean.

In my case:

sudo -E add-apt-repository ppa:linuxuprising/java

sudo apt-get update

sudo apt install  oracle-java12-installer

that works fine

You can set a bucket policy as detailed in this blog post:

http://ariejan.net/2010/12/24/public-readable-amazon-s3-bucket-policy/

As per @robbyt's suggestion, create a bucket policy with the following JSON:

{
  "Version": "2008-10-17",
  "Statement": [{
    "Sid": "AllowPublicRead",
    "Effect": "Allow",
    "Principal": { "AWS": "*" },
    "Action": ["s3:GetObject"],
    "Resource": ["arn:aws:s3:::bucket/*" ]
  }]
}

Important: replace bucket in the Resource line with the name of your bucket.

Try this

package main

import "fmt"
import "strconv"

func FloatToString(input_num float64) string {
    // to convert a float number to a string
    return strconv.FormatFloat(input_num, 'f', 6, 64)
}

func main() {
    fmt.Println(FloatToString(21312421.213123))
}

If you just want as many digits precision as possible, then the special precision -1 uses the smallest number of digits necessary such that ParseFloat will return f exactly. Eg

strconv.FormatFloat(input_num, 'f', -1, 64)

Personally I find fmt easier to use. (Playground link)

fmt.Printf("x = %.6f\n", 21312421.213123)

Or if you just want to convert the string

fmt.Sprintf("%.6f", 21312421.213123)

Is it a spelling error in your closing tag ie:

</CustomErrors> instead of </CustomError>?

Too late to answer but if your input is in form of ASCII bytes, then you could try this solution:

function convertArrToString(rArr){
 //Step 1: Convert each element to character
 let tmpArr = new Array();
 rArr.forEach(function(element,index){
    tmpArr.push(String.fromCharCode(element));
});
//Step 2: Return the string by joining the elements
return(tmpArr.join(""));
}

function convertArrToHexNumber(rArr){
  return(parseInt(convertArrToString(rArr),16));
}

A monad is an array of functions

(Pst: an array of functions is just a computation).

Actually, instead of a true array (one function in one cell array) you have those functions chained by another function >>=. The >>= allows to adapt the results from function i to feed function i+1, perform calculations between them or, even, not to call function i+1.

The types used here are "types with context". This is, a value with a "tag". The functions being chained must take a "naked value" and return a tagged result. One of the duties of >>= is to extract a naked value out of its context. There is also the function "return", that takes a naked value and puts it with a tag.

An example with Maybe. Let's use it to store a simple integer on which make calculations.

-- a * b
multiply :: Int -> Int -> Maybe Int
multiply a b = return  (a*b)

-- divideBy 5 100 = 100 / 5
divideBy :: Int -> Int -> Maybe Int
divideBy 0 _ = Nothing -- dividing by 0 gives NOTHING
divideBy denom num = return (quot num denom) -- quotient of num / denom

-- tagged value
val1 = Just 160 

-- array of functions feeded with val1
array1 = val1 >>= divideBy 2  >>= multiply 3 >>= divideBy  4 >>= multiply 3

-- array of funcionts created with the do notation
-- equals array1 but for the feeded val1
array2 :: Int -> Maybe Int
array2 n = do
       v <- divideBy 2  n
       v <- multiply 3 v
       v <- divideBy 4 v
       v <- multiply 3 v
       return v

-- array of functions, 
-- the first >>= performs 160 / 0, returning Nothing
-- the second >>= has to perform Nothing >>= multiply 3 ....
-- and simply returns Nothing without calling multiply 3 ....
array3 = val1 >>= divideBy 0  >>= multiply 3 >>= divideBy  4 >>= multiply 3

main = do
     print array1
     print (array2 160)
     print array3

Just to show that monads are array of functions with helper operations, consider the equivalent to the above example, just using a real array of functions

type MyMonad = [Int -> Maybe Int] -- my monad as a real array of functions

myArray1 = [divideBy 2, multiply 3, divideBy 4, multiply 3]

-- function for the machinery of executing each function i with the result provided by function i-1
runMyMonad :: Maybe Int -> MyMonad -> Maybe Int
runMyMonad val [] = val
runMyMonad Nothing _ = Nothing
runMyMonad (Just val) (f:fs) = runMyMonad (f val) fs

And it would be used like this:

print (runMyMonad (Just 160) myArray1)

EDIT: The below answer no longer works see here

If the file you try to recover has Content-Encoding: gzip in the header section, and you are using linux (or as in my case, you have Cygwin installed) you can do the following:

1. visit chrome://view-http-cache/ and click the page you want to recover
2. copy the last (fourth) section of the page verbatim to a text file (say: a.txt)
3. xxd -r a.txt| gzip -d

Note that other answers suggest passing -p option to xxd - I had troubles with that presumably because the fourth section of the cache is not in the "postscript plain hexdump style" but in a "default style".

It also does not seem necessary to replace double spaces with a single space, as chrome_xxd.py is doing (in case it is necessary you can use sed 's/ / /g' for that).

I use the below

contentType: 'application/json',
data: JSON.stringify(SendData),

If you use numpy, this is easy:

slice = arr[:2,:2]

or if you want the 0's,

slice = arr[0:2,0:2]

You'll get the same result.

*note that slice is actually the name of a builtin-type. Generally, I would advise giving your object a different "name".

Another way, if you're working with lists of lists*:

slice = [arr[i][0:2] for i in range(0,2)]

(Note that the 0's here are unnecessary: [arr[i][:2] for i in range(2)] would also work.).

What I did here is that I take each desired row 1 at a time (arr[i]). I then slice the columns I want out of that row and add it to the list that I'm building.

If you naively try: arr[0:2] You get the first 2 rows which if you then slice again arr[0:2][0:2], you're just slicing the first two rows over again.

*This actually works for numpy arrays too, but it will be slow compared to the "native" solution I posted above.

the simplest way what I found from a tutorial of "TraversyMedia" is that just use https://cors-anywhere.herokuapp.com in 'axios' or 'fetch' api

https://cors-anywhere.herokuapp.com/{type_your_url_here} 

e.g.

axios.get(`https://cors-anywhere.herokuapp.com/https://www.api.com/`)

and in your case edit url as

url: 'https://cors-anywhere.herokuapp.com/https://www.api.com',

Go to menu , search for Regional Settings. Switch to Keyboard layouts tab. Click Options button. Search for Key(s) to change layout. There isn't a default one so you have to tick the combination you like. Enjoy.

One of the first differences that I can recall from top of my head are multiple domains running in the same server, partial resource retrieval, this allows you to retrieve and speed up the download of a resource (it's what almost every download accelerator does).

If you want to develop an application like a website or similar, you don't need to worry too much about the differences but you should know the difference between GET and POST verbs at least.

Now if you want to develop a browser then yes, you will have to know the complete protocol as well as if you are trying to develop a HTTP server.

If you are only interested in knowing the HTTP protocol I would recommend you starting with HTTP/1.1 instead of 1.0.

$ rails server -b $IP -p $PORT - that solved the same problem for me

setTimeout(function() {
     $('.message').hide();
}, 2000);

This will hide the '.message' div after 2 seconds.

I got

No 'Access-Control-Allow-Origin' header is present

and the problem was with the URL I was providing. I was providing the URL without a route, e.g., https://misty-valley-1234.herokuapp.com/.

When I added a path it worked, e.g., https://misty-valley-1234.herokuapp.com/messages. With GET requests it worked either way but with POST responses it only worked with the added path.

I'd suggest using such extension method:

public static class DataColumnCollectionExtensions
{
    public static IEnumerable<DataColumn> AsEnumerable(this DataColumnCollection source)
    {
        return source.Cast<DataColumn>();
    }
}

And therefore:

string[] columnNames = dataTable.Columns.AsEnumerable().Select(column => column.Name).ToArray();

You may also implement one more extension method for DataTable class to reduce code:

public static class DataTableExtensions
{
    public static IEnumerable<DataColumn> GetColumns(this DataTable source)
    {
        return source.Columns.AsEnumerable();
    }
}

And use it as follows:

string[] columnNames = dataTable.GetColumns().Select(column => column.Name).ToArray();

.cont{_x000D_
height: 100px;_x000D_
overflow-x: hidden;_x000D_

   <li>9</li>_x000D_
   <li>10</li>  _x000D_
 </ul>_x000D_
</div>

1. Run code snippet to see the effect. (PS: If Run code snippet is not working, try this: https://jsfiddle.net/Yeshen/xm2yLksu/3/ )

2. How it work:

Default overflow is scroll from top to bottom.

transform: rotate(180deg) can make it scroll or load dynamic block from bottom to top.

3. Original idea:

Watermarked with ?“for development purposes only” is returned when any of the following is true:

1. The request is missing an API key.
2. Billing has not been enabled on your account.
3. The provided billing method is invalid (for example an expired credit card).
4. A self-imposed daily limit has been exceeded.

As stated before - VueJS simply can't track those operations(array elements assignment). All operations that are tracked by VueJS with array are here. But I'll copy them once again:

• push()
• pop()
• shift()
• unshift()
• splice()
• sort()
• reverse()

During development, you face a problem - how to live with that :).

push(), pop(), shift(), unshift(), sort() and reverse() are pretty plain and help you in some cases but the main focus lies within the splice(), which allows you effectively modify the array that would be tracked by VueJs. So I can share some of the approaches, that are used the most working with arrays.

You need to replace Item in Array:

// note - findIndex might be replaced with some(), filter(), forEach() 
// or any other function/approach if you need 
// additional browser support, or you might use a polyfill
const index = this.values.findIndex(item => {
          return (replacementItem.id === item.id)
        })
this.values.splice(index, 1, replacementItem)

Note: if you just need to modify an item field - you can do it just by:

this.values[index].itemField = newItemFieldValue

And this would be tracked by VueJS as the item(Object) fields would be tracked.

You need to empty the array:

this.values.splice(0, this.values.length)

Actually you can do much more with this function splice() - w3schools link You can add multiple records, delete multiple records, etc.

Vue.set() and Vue.delete()

Vue.set() and Vue.delete() might be used for adding field to your UI version of data. For example, you need some additional calculated data or flags within your objects. You can do this for your objects, or list of objects(in the loop):

 Vue.set(plan, 'editEnabled', true) //(or this.$set)

And send edited data back to the back-end in the same format doing this before the Axios call:

 Vue.delete(plan, 'editEnabled') //(or this.$delete)

I was getting the exact same error, however I solved it by running $false first and then $true.

Of course it does. After replacing the variable, it reads [ !-z ], which is not a valid [ command. Use double quotes, or [[.

if [ ! -z "$errorstatus" ]

if [[ ! -z $errorstatus ]]

As of Bootstrap 3, you can use Panel classes:

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

In Bootstrap 4, you can use Border classes:

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

A simple string.Concat() is what you need.

string[] test = new string[2];

test[0] = "Hello ";
test[1] = "World!";

string result = string.Concat(test);

If you also need to add a seperator (space, comma etc) then, string.Join() should be used.

string[] test = new string[2];

test[0] = "Red";
test[1] = "Blue";

string result = string.Join(",", test);

If you have to perform this on a string array with hundereds of elements than string.Join() is better by performace point of view. Just give a "" (blank) argument as seperator. StringBuilder can also be used for sake of performance, but it will make code a bit longer.

UNI: For UNIQUE:

• It is a set of one or more columns of a table to uniquely identify the record.
• A table can have multiple UNIQUE key.
• It is quite like primary key to allow unique values but can accept one null value which primary key does not.

PRI: For PRIMARY:

• It is also a set of one or more columns of a table to uniquely identify the record.
• A table can have only one PRIMARY key.
• It is quite like UNIQUE key to allow unique values but does not allow any null value.

MUL: For MULTIPLE:

• It is also a set of one or more columns of a table which does not identify the record uniquely.
• A table can have more than one MULTIPLE key.
• It can be created in table on index or foreign key adding, it does not allow null value.
• It allows duplicate entries in column.
• If we do not specify MUL column type then it is quite like a normal column but can allow null entries too hence; to restrict such entries we need to specify it.
• If we add indexes on column or add foreign key then automatically MUL key type added.

The script element that loads the API is missing the required authentication parameter. If you are using the standard Maps JavaScript API, you must use a key parameter with a valid API key. If you are a Premium Plan customer, you must use either a client parameter with your client ID or a key parameter with a valid API key.

See the guide to API keys and client IDs.

Use this function:

merge(target, source, mutable = false) {
        const newObj = typeof target == 'object' ? (mutable ? target : Object.assign({}, target)) : {};
        for (const prop in source) {
            if (target[prop] == null || typeof target[prop] === 'undefined') {
                newObj[prop] = source[prop];
            } else if (Array.isArray(target[prop])) {
                newObj[prop] = source[prop] || target[prop];
            } else if (target[prop] instanceof RegExp) {
                newObj[prop] = source[prop] || target[prop];
            } else {
                newObj[prop] = typeof source[prop] === 'object' ? this.merge(target[prop], source[prop]) : source[prop];
            }
        }
        return newObj;
    }

Several of the suggestions above use global variables. This is not a good solution for the problem. The count is specific to one element, and you can use jQuery's data function to bind an item of data to an element:

$('#counter').data('count', 0);
$('#update').click(function(){
    $('#counter').html(function(){
        var $this = $(this),
            count = $this.data('count') + 1;

        $this.data('count', count);
        return count;
    });
});

Note also that this uses the callback syntax of html to make the code more fluent and fast.

The innovation is in the type safety and transparency. Although you don't declare types of lambda expressions, they are inferred, and can be used by code search, static analysis, refactoring tools, and runtime reflection.

For example, before you might have used SQL and could get an SQL injection attack, because a hacker passed a string where a number was normally expected. Now you would use a LINQ lambda expression, which is protected from that.

Building a LINQ API on pure delegates is not possible, because it requires combining expression trees together before evaluating them.

In 2016 most of the popular languages have lambda expression support, and C# was one of the pioneers in this evolution among the mainstream imperative languages.

Using git 2.9 (precisely 2.9.2.windows.1) git reset HEAD^ prompts for more; not sure what is expected input here. Please refer below screenshot

Found other solution git reset HEAD~#numberOfCommits using which we can choose to select number of local commits you want to reset by keeping your changes intact. Hence, we get an opportunity to throw away all local commits as well as limited number of local commits.

Refer below screenshots showing git reset HEAD~1 in action:

@kgiannakakis answer is fully correct, but if someone stuck into this problem and uses Java 6 on Linux (by example, Mint 19 Cinnamon), MAXIMIZED_BOTH state is sometimes not applied.

You could try to call pack() method after setting this state.

Code example:

public MainFrame() {
    setContentPane(contentPanel); //some JPanel is here
    setPreferredSize(new Dimension(1200, 800));
    setMinimumSize(new Dimension(1200, 800));
    setSize(new Dimension(1200, 800));
    setExtendedState(JFrame.MAXIMIZED_BOTH);
    pack();
}

This is not necessary if you are using Java 7+ or Java 6 on Windows.

I am using ipython 2.0, so just two line.

from IPython.display import Image
Image(filename='output1.png')

This is borderline programming, but look into using tr:

$ echo "this is just a test" | tr -s ' ' | tr ' ' '_'

Should do it. The first invocation squeezes the spaces down, the second replaces with underscore. You probably need to add TABs and other whitespace characters, this is for spaces only.

You will not be able to retrieve a plain text password from wordpress.

Wordpress use a 1 way encryption to store the passwords using a variation of md5. There is no way to reverse this.

See this article for more info http://wordpress.org/support/topic/how-is-the-user-password-encrypted-wp_hash_password

Seconds with 2 decimal spaces:

Dim startTime As Single 'start timer
MsgBox ("run time: " & Format((Timer - startTime) / 1000000, "#,##0.00") & " seconds") 'end timer

Milliseconds:

Dim startTime As Single 'start timer
MsgBox ("run time: " & Format((Timer - startTime), "#,##0.00") & " milliseconds") 'end timer

Milliseconds with comma seperator:

Dim startTime As Single 'start timer
MsgBox ("run time: " & Format((Timer - startTime) * 1000, "#,##0.00") & " milliseconds") 'end timer

Just leaving this here for anyone that was looking for a simple timer formatted with seconds to 2 decimal spaces like I was. These are short and sweet little timers I like to use. They only take up one line of code at the beginning of the sub or function and one line of code again at the end. These aren't meant to be crazy accurate, I generally don't care about anything less then 1/100th of a second personally, but the milliseconds timer will give you the most accurate run time of these 3. I've also read you can get the incorrect read out if it happens to run while crossing over midnight, a rare instance but just FYI.

Some of the system headers provide a forward declaration of std::stringstream without the definition. This makes it an 'incomplete type'. To fix that you need to include the definition, which is provided in the <sstream> header:

#include <sstream>

This is how I did it...

<form action="../<SamePage>/" method="post">

<?php
    if ( $_POST['drop_down'] == "")
    {
    $selected = "";
    }
    else
    {
    $selected = "selected";
    }
?>

<select name="select" size="1">

  <option value="1" <?php $selected ?>>One</option>
     ////////  OR  ////////
  <option value="2" $selected>Two</option>

</select>
</form>

This is against the general mechanism of Stream. Say you can split Stream S0 to Sa and Sb like you wanted. Performing any terminal operation, say count(), on Sa will necessarily "consume" all elements in S0. Therefore Sb lost its data source.

Previously, Stream had a tee() method, I think, which duplicate a stream to two. It's removed now.

Stream has a peek() method though, you might be able to use it to achieve your requirements.

$suppress_localhost = false;

This did the trick for me.

From the documentation Restore activity UI state using saved instance state it is stated as:

Instead of restoring the state during onCreate() you may choose to implement onRestoreInstanceState(), which the system calls after the onStart() method. The system calls onRestoreInstanceState() only if there is a saved state to restore, so you do not need to check whether the Bundle is null:

IMO, this is more clear way than checking this at onCreate, and better fits with single responsiblity principle.

I had the same issue, and here's how it's solved in my case.

The original questions seems to come from confusion about a) where is the file, and b) where is it being looked for (and why can't we find it there when we do a locate or grep). I think Alnitak's point was that you want to find where it was linked to - but grep will not show you a link, right? The file doesn't live there, since it's a link it is just a pointer. You still need to know where to put the link.

my sock file is definitely in /tmp and the ERROR I am getting is looking for it in /var/lib/ (not just /var) I have linked to /var and /var/lib now, and I still am getting the error "Cannot connect to local MySQL server through socket 'var/lib/mysql.sock' (2)".

Note the (2) after the error.... I found on another thread that this means the socket might be indeed attempted to be used, but something is wrong with the socket itself - so to shut down the machine - completely - so that the socket closes. Then a restart should fix it. I tried this, but it didn't work for me (now I question if I restarted too quickly? really?) Maybe it will be a solution for someone else.

uint16_t is guaranteed to be a unsigned integer that is 16 bits large

unsigned short int is guaranteed to be a unsigned short integer, where short integer is defined by the compiler (and potentially compiler flags) you are currently using. For most compilers for x86 hardware a short integer is 16 bits large.

Also note that per the ANSI C standard only the minimum size of 16 bits is defined, the maximum size is up to the developer of the compiler

Minimum Type Limits

Any compiler conforming to the Standard must also respect the following limits with respect to the range of values any particular type may accept. Note that these are lower limits: an implementation is free to exceed any or all of these. Note also that the minimum range for a char is dependent on whether or not a char is considered to be signed or unsigned.

Type Minimum Range

signed char     -127 to +127
unsigned char      0 to 255
short int     -32767 to +32767
unsigned short int 0 to 65535

Since it is hard to find good themes for IntelliJ IDEA, I've created this site: https://github.com/sdvoynikov/color-themes (note: site archived to GitHub repo) where there is a large collection of themes. There are 270 themes for now and the site is growing.

P.S.: Help me and other people — do not forget to upvote when you download themes from this site!

expr match "$LIST" '$SOURCE'

don't work because of this function search $SOURCE from begin of the string and return the position just after pattern $SOURCE if found else 0. So you must write another code:

expr match "$LIST" '.*'"$SOURCE" or expr "$LIST" : '.*'"$SOURCE"

The expression $SOURCE must be double quoted so as a parser may set substitution. Single quoted not substitute and the code above will search textual string $SOURCE from the beginning of the $LIST. If you need the beginning of the string subtract the length $SOURCE e.g ${#SOURCE}. You may write also

expr "$LIST" : ".*\($SOURCE\)"

This function just extract $SOURCE from $LIST and return it. You'll get empty string else. But they problem with double double quote. I don't know how it resolve without using additional variable. It's light solution. So you may write in C. There is ready function strstr. Don't use expr index, So is very attractive. But index search not substring and only first char.

Regarding your question (b), be aware that the Websocket specification hasn't been finalised. According to the W3C:

Implementors should be aware that this specification is not stable.

Personally I regard Websockets to be waaay too bleeding edge to use at present. Though I'll probably find them useful in a year or so.

For Python 3 above, use:

sudo apt-get install python3-dateutil

Complete Solution in JavaScript for all browsers

The code above and most of the solutions are perfect. However, I think the most liked one "short answer" which is incomplete.

So here's the entire answer. in JavaScript with native Support for IE 7 as well.

var form = document.getElementById("testForm");
form.addEventListener("submit",function(e){e.preventDefault(); return false;});

This solution will now prevent the user from submit using the enter Key and will not reload the page, or take you to the top of the page, if your form is somewhere below.

function routeToRoom(userId, passw, cb) {
    var roomId = 0;
    var nStore = require('nstore/lib/nstore').extend(require('nstore/lib/nstore/query')());
    var users = nStore.new('data/users.db', function() {
        users.find({
            user: userId,
            pass: passw
        }, function(err, results) {
            if (err) {
                roomId = -1;
            } else {
                roomId = results.creationix.room;
            }
            cb(roomId);
        });
    });
}
routeToRoom("alex", "123", function(id) {
    console.log(id);    
});

You need to use callbacks. That's how asynchronous IO works. Btw sys.puts is deprecated

Make sure you have a service started and listening on the port.

netstat -ln | grep 8080

and

sudo netstat -tulpn

You say you have an index, the explain says otherwise. However, if you really do, this is how to continue:

If you have an index on the column, and MySQL decides not to use it, it may by because:

1. There's another index in the query MySQL deems more appropriate to use, and it can use only one. The solution is usually an index spanning multiple columns if their normal method of retrieval is by value of more then one column.
2. MySQL decides there are to many matching rows, and thinks a tablescan is probably faster. If that isn't the case, sometimes an ANALYZE TABLE helps.
3. In more complex queries, it decides not to use it based on extremely intelligent thought-out voodoo in the query-plan that for some reason just not fits your current requirements.

In the case of (2) or (3), you could coax MySQL into using the index by index hint sytax, but if you do, be sure run some tests to determine whether it actually improves performance to use the index as you hint it.

I solved my problem with this commands:

cat __mydomain_com.crt __mydomain_com.ca-bundle > __mydomain_com_combine.crt

and after:

cat __mydomain_com_combine.crt COMODORSADomainValidationSecureServerCA.crt 
COMODORSAAddTrustCA.crt AddTrustExternalCARoot.crt > mydomain.pem

And in my domain nginx .conf I put on the server 443:

ssl_certificate          ssl/mydomain.pem;
ssl_certificate_key      ssl/mydomain.private.key;

I don't forget restart your "Nginx"

service nginx restart

for strings in panda take pd.isnull:

if not pd.isnull(atext):
  for word in nltk.word_tokenize(atext):

the function as feature extraction for NLTK

def act_features(atext):
features = {}
if not pd.isnull(atext):
  for word in nltk.word_tokenize(atext):
    if word not in default_stopwords:
      features['cont({})'.format(word.lower())]=True
return features

I've been using:

@media only screen and (min-width: 768px) {
    /* tablets and desktop */
}

@media only screen and (max-width: 767px) {
    /* phones */
}

@media only screen and (max-width: 767px) and (orientation: portrait) {
    /* portrait phones */
}

It keeps things relatively simple and allows you to do something a bit different for phones in portrait mode (a lot of the time I find myself having to change various elements for them).

To set parameters to your HttpPostRequest you can use BasicNameValuePair, something like this :

    HttpClient httpclient;
    HttpPost httpPost;
    ArrayList<NameValuePair> postParameters;
    httpclient = new DefaultHttpClient();
    httpPost = new HttpPost("your login link");


    postParameters = new ArrayList<NameValuePair>();
    postParameters.add(new BasicNameValuePair("param1", "param1_value"));
    postParameters.add(new BasicNameValuePair("param2", "param2_value"));

    httpPost.setEntity(new UrlEncodedFormEntity(postParameters, "UTF-8"));

    HttpResponse response = httpclient.execute(httpPost);

OData (Open Data Protocol) is an OASIS standard that defines the best practice for building and consuming RESTful APIs. OData helps you focus on your business logic while building RESTful APIs without having to worry about the approaches to define request and response headers, status codes, HTTP methods, URL conventions, media types, payload formats and query options etc. OData also guides you about tracking changes, defining functions/actions for reusable procedures and sending asynchronous/batch requests etc. Additionally, OData provides facility for extension to fulfil any custom needs of your RESTful APIs.

OData RESTful APIs are easy to consume. The OData metadata, a machine-readable description of the data model of the APIs, enables the creation of powerful generic client proxies and tools. Some of them can help you interact with OData even without knowing anything about the protocol. The following 6 steps demonstrate 6 interesting scenarios of OData consumption across different programming platforms. But if you are a non-developer and would like to simply play with OData, XOData is the best start for you.

using flex

 <View style={{ flexDirection: 'row',}}>
                  <Text style={{fontSize: 12, lineHeight: 30, color:'#9394B3' }}>left</Text>

To link from a page to another section of the page, I navigate through the page depending on the page's location to the other, at the URL bar, and add the #id. So what I mean;

<a href = "../#the_part_that_you_want">This takes you #the_part_that_you_want at the page before</a>

Old question, but half a decade later, it’s worth revisiting. Here I am only discussing the selector aspect of jQuery.

document.querySelector[All] is supported by all current browsers, down to IE8, so compatibility is no longer an issue. I have also found no performance issues to speak of (it was supposed to be slower than document.getElementById, but my own testing suggests that it’s slightly faster).

Therefore when it comes to manipulating an element directly, it is to be preferred over jQuery.

For example:

var element=document.querySelector('h1');
element.innerHTML='Hello';

is vastly superior to:

var $element=$('h1');
$element.html('hello');

In order to do anything at all, jQuery has to run through a hundred lines of code (I once traced through code such as the above to see what jQuery was actually doing with it). This is clearly a waste of everyone’s time.

The other significant cost of jQuery is the fact that it wraps everything inside a new jQuery object. This overhead is particularly wasteful if you need to unwrap the object again or to use one of the object methods to deal with properties which are already exposed on the original element.

Where jQuery has an advantage, however, is in how it handles collections. If the requirement is to set properties of multiple elements, jQuery has a built-in each method which allows something like this:

var $elements=$('h2');  //  multiple elements
$elements.html('hello');

To do so with Vanilla JavaScript would require something like this:

var elements=document.querySelectorAll('h2');
elements.forEach(function(e) {
    e.innerHTML='Hello';
});

which some find daunting.

jQuery selectors are also slightly different, but modern browsers (excluding IE8) won’t get much benefit.

As a rule, I caution against using jQuery for new projects:

• jQuery is an external library adding to the overhead of the project, and to your dependency on third parties.
• jQuery function is very expensive, processing-wise.
• jQuery imposes a methodology which needs to be learned and may compete with other aspects of your code.
• jQuery is slow to expose new features in JavaScript.

If none of the above matters, then do what you will. However, jQuery is no longer as important to cross-platform development as it used to be, as modern JavaScript and CSS go a lot further than they used to.

This makes no mention of other features of jQuery. However, I think that they, too, need a closer look.

if you wish to make it dynamically with an animation:

view.animate()
    .rotation(180)
    .start();

THATS IT

I'm not entirely sure of the general purpose of the function, but you could always do this:

function getMachine(color, qty) {
    var retval;
    $("#getMachine li").each(function() {
        var thisArray = $(this).text().split("~");
        if(thisArray[0] == color&& qty>= parseInt(thisArray[1]) && qty<= parseInt(thisArray[2])) {
            retval = thisArray[3];
            return false;
        }
    });
    return retval;
}

var retval = getMachine(color, qty);

This is FAQ 7.10. Others have shown how to apply this to a single column in a data frame, or to multiple columns in a data frame. But this is really treating the symptom, not curing the cause.

A better approach is to use the colClasses argument to read.table and related functions to tell R that the column should be numeric so that it never creates a factor and creates numeric. This will put in NA for any values that do not convert to numeric.

Another better option is to figure out why R does not recognize the column as numeric (usually a non numeric character somewhere in that column) and fix the original data so that it is read in properly without needing to create NAs.

Best is a combination of the last 2, make sure the data is correct before reading it in and specify colClasses so R does not need to guess (this can speed up reading as well).

the best way i found was to set the image you want to view responsively as a background image and sent a css property for the div as cover.

background-image : url('YOUR URL');
background-size : cover

As aditional information on @Quentin answer, and as he rightly says, background CSS property itself, is a shorthand for:

background-color
background-image
background-repeat
background-attachment
background-position

That's mean, you can group all styles in one, like:

background: red url(../img.jpg) 0 0 no-repeat fixed;

This would be (in this example):

background-color: red;
background-image: url(../img.jpg);
background-repeat: no-repeat;
background-attachment: fixed;
background-position: 0 0;

So... when you set: background:none;
you are saying that all the background properties are set to none...
You are saying that background-image: none; and all the others to the initial state (as they are not being declared).
So, background:none; is:

background-color: initial;
background-image: none;
background-repeat: initial;
background-attachment: initial;
background-position: initial;

Now, when you define only the color (in your case transparent) then you are basically saying:

background-color: transparent;
background-image: initial;
background-repeat: initial;
background-attachment: initial;
background-position: initial;

I repeat, as @Quentin rightly says the default transparent and none values in this case are the same, so in your example and for your original question, No, there's no difference between them.

But!.. if you say background:none Vs background:red then yes... there's a big diference, as I say, the first would set all properties to none/default and the second one, will only change the color and remains the rest in his default state.

So in brief:

Short answer: No, there's no difference at all (in your example and orginal question)
Long answer: Yes, there's a big difference, but depends directly on the properties granted to attribute.

Upd1: Initial value (aka default)

Initial value the concatenation of the initial values of its longhand properties:

background-image: none
background-position: 0% 0%
background-size: auto auto
background-repeat: repeat
background-origin: padding-box
background-style: is itself a shorthand, its initial value is the concatenation of its own longhand properties
background-clip: border-box
background-color: transparent

See more background descriptions here

Upd2: Clarify better the background:none; specification.

Click the items in the list view. Add a button that will edit the selected items. Add the code

try
{              
    LSTDEDUCTION.SelectedItems[0].SubItems[1].Text = txtcarName.Text;
    LSTDEDUCTION.SelectedItems[0].SubItems[0].Text = txtcarBrand.Text;
    LSTDEDUCTION.SelectedItems[0].SubItems[2].Text = txtCarName.Text;
}
catch{}

We could type our variable with an explicit return type:

const script: HTMLScriptElement = document.getElementsByName(id).item(0);

Or assert as (needed with TSX):

const script = document.getElementsByName(id).item(0) as HTMLScriptElement;

Or in simpler cases assert with angle-bracket syntax.

A type assertion is like a type cast in other languages, but performs no special checking or restructuring of data. It has no runtime impact, and is used purely by the compiler.

Documentation:

TypeScript - Basic Types - Type assertions

The following should work, but you may need to change the format:

echo date('l F jS, Y (m-d-Y)', strtotime('+3 months', strtotime($DateToAdjust)));

Here's a slightly updated version of Chris Herring's solution, taking into account that you can use innerHTML as well instead of a creating a new text node:

function insertCss( code ) {
    var style = document.createElement('style');
    style.type = 'text/css';

    if (style.styleSheet) {
        // IE
        style.styleSheet.cssText = code;
    } else {
        // Other browsers
        style.innerHTML = code;
    }

    document.getElementsByTagName("head")[0].appendChild( style );
}

Alright, think I got it...

Little background first: The reason I needed this was to stick Angular on top of Node Express and have Jade process my partials for me.

So here's whatchya gotta do... (drink beer and spend 20+ hours on it first!!!)...

When you set up your module, save the $routeProvider globally:

// app.js:
var routeProvider
    , app = angular.module('Isomorph', ['ngResource']).config(function($routeProvider){

        routeProvider = $routeProvider;
        $routeProvider
            .when('/', {templateUrl: '/login', controller: 'AppCtrl'})
            .when('/home', {templateUrl: '/', controller: 'AppCtrl'})
            .when('/login', {templateUrl: '/login', controller: 'AppCtrl'})
            .when('/SAMPLE', {templateUrl: '/SAMPLE', controller: 'SAMPLECtrl'})
            .when('/map', {templateUrl: '/map', controller: 'MapCtrl'})
            .when('/chat', {templateUrl: '/chat', controller: 'ChatCtrl'})
            .when('/blog', {templateUrl: '/blog', controller: 'BlogCtrl'})
            .when('/files', {templateUrl: '/files', controller: 'FilesCtrl'})
            .when('/tasks', {templateUrl: '/tasks', controller: 'TasksCtrl'})
            .when('/tasks/new', {templateUrl: '/tasks/new', controller: 'NewTaskCtrl'})
            .when('/tasks/:id', {templateUrl: '/tasks', controller: 'ViewTaskCtrl'})
            .when('/tasks/:id/edit', {templateUrl: '/tasks', controller: 'EditTaskCtrl'})
            .when('/tasks/:id/delete', {templateUrl: '/tasks', controller: 'DeleteTaskCtrl'})
        .otherwise({redirectTo: '/login'});

});

// ctrls.js
...
app.controller('EditTaskCtrl', function($scope, $routeParams, $location, $http){

    var idParam = $routeParams.id;
    routeProvider.when('/tasks/:id/edit/', {templateUrl: '/tasks/' + idParam + '/edit'});
    $location.path('/tasks/' + idParam + '/edit/');

That may be more info than what was needed...

• Basically, you'll wanna store your Module's $routeProvider var globally, eg as routeProvider so that it can be accessed by your Controllers.

• Then you can just use routeProvider and create a NEW route (you can't 'RESET a route' / 'REpromise'; you must create a new one), I just added a slash (/) at the end so that it is as semantic as the first.

• Then (inside your Controller), set the templateUrl to the view you want to hit.

• Take out the controller property of the .when() object, lest you get an infinite request loop.

• And finally (still inside the Controller), use $location.path() to redirect to the route that was just created.

If you're interested in how to slap an Angular app onto an Express app, you can fork my repo here: https://github.com/cScarlson/isomorph.

And this method also allows for you to keep the AngularJS Bidirectional Data-Bindings in case you want to bind your HTML to your database using WebSockets: otherwise without this method, your Angular data-bindings will just output {{model.param}}.

If you clone this at this time, you'll need mongoDB on your machine to run it.

Hope this solves this issue!

If you're using a JetBrains IDE (like IntelliJ IDEA, Android Studio, PyCharm), you can drag the patch file and drop it inside the IDE, and a dialog will appear, showing the patch's content. All you have to do now is to click "Apply patch", and a commit will be created.

git commit is to commit the files that is staged in the local repo. git push is to fast-forward merge the master branch of local side with the remote master branch. But the merge won't always success. If rejection appears, you have to pull so that you can make a successful git push.

Ack! Constant strings:

const char *strings[] = {"one","two","three"};

If I remember correctly.

Oh, and you want to use strcpy for assignment, not the = operator. strcpy_s is safer, but it's neither in C89 nor in C99 standards.

char arr[MAX_NUMBER_STRINGS][MAX_STRING_SIZE]; 
strcpy(arr[0], "blah");

Update: Thomas says strlcpy is the way to go.

You'll want to add a Symbolic Breakpoint. Apple provides an excellent guide on how to do this.

1. Open the Breakpoint Navigator cmd+7 (cmd+8 in Xcode 9)
2. Click the Add button in the lower left
3. Select Add Symbolic Breakpoint...
4. Where it says Symbol just type in UIViewAlertForUnsatisfiableConstraints

You can also treat it like any other breakpoint, turning it on and off, adding actions, or log messages.

Targeting learner, who are novice to Java and/or Nested Classes

Nested classes can be either:
1. Static Nested classes.
2. Non Static Nested classes. (also known as Inner classes) =>Please remember this

1.Inner classes
Example:

class OuterClass  {
/*  some code here...*/
     class InnerClass  {  }
/*  some code here...*/
}

Inner classes are subsets of nested classes:

• inner class is a specific type of nested class
• inner classes are subsets of nested classes
• You can say that an inner class is also a nested class, but you can NOT say that a nested class is also an inner class.

Specialty of Inner class:

• instance of an inner class has access to all of the members of the outer class, even those that are marked “private”

2.Static Nested Classes:
Example:

class EnclosingClass {
  static class Nested {
    void someMethod() { System.out.println("hello SO"); }
  }
}

Case 1:Instantiating a static nested class from a non-enclosing class

class NonEnclosingClass {

  public static void main(String[] args) {
    /*instantiate the Nested class that is a static
      member of the EnclosingClass class:
    */

    EnclosingClass.Nested n = new EnclosingClass.Nested(); 
    n.someMethod();  //prints out "hello"
  }
}

Case 2:Instantiating a static nested class from an enclosing class

class EnclosingClass {

  static class Nested {
    void anotherMethod() { System.out.println("hi again"); } 
  }

  public static void main(String[] args) {
    //access enclosed class:

    Nested n = new Nested(); 
    n.anotherMethod();  //prints out "hi again"
  }

}

Specialty of Static classes:

• Static inner class would only have access to the static members of the outer class, and have no access to non-static members.

Conclusion:
Question: What is the main difference between a inner class and a static nested class in Java?
Answer: just go through specifics of each class mentioned above.

datetime.replace() will provide the best options. Also, it provides facility for replacing day, year, and month.

Suppose we have a datetime object and date is represented as: "2017-05-04"

>>> from datetime import datetime
>>> date = datetime.strptime('2017-05-04',"%Y-%m-%d")
>>> print(date)
2017-05-04 00:00:00
>>> date = date.replace(minute=59, hour=23, second=59, year=2018, month=6, day=1)
>>> print(date)
2018-06-01 23:59:59

Some short background:

Unfortunately the Unix API doesn't provide a running program with the full path to the executable. In fact, the program executing yours can provide whatever it wants in the field that normally tells your program what it is. There are, as all the answers point out, various heuristics for finding likely candidates. But nothing short of searching the entire filesystem will always work, and even that will fail if the executable is moved or removed.

But you don't want the Perl executable, which is what's actually running, but the script it is executing. And Perl needs to know where the script is to find it. It stores this in __FILE__, while $0 is from the Unix API. This can still be a relative path, so take Mark's suggestion and canonize it with File::Spec->rel2abs( __FILE__ );

worked for me to open new tab on google-chrome:

import webbrowser

webbrowser.open_new_tab("http://www.google.com")

You do not need any client side code if doing this is ASP.NET. The example below is a boostrap input box with a search button with an fontawesome icon.

You will see that in place of using a regular < div > tag with a class of "input-group" I have used a asp:Panel. The DefaultButton property set to the id of my button, does the trick.

In example below, after typing something in the input textbox, you just hit enter and that will result in a submit.

<asp:Panel DefaultButton="btnblogsearch" runat="server" CssClass="input-group blogsearch">
<asp:TextBox ID="txtSearchWords" CssClass="form-control" runat="server" Width="100%" Placeholder="Search for..."></asp:TextBox>
<span class="input-group-btn">
    <asp:LinkButton ID="btnblogsearch" runat="server" CssClass="btn btn-default"><i class="fa fa-search"></i></asp:LinkButton>
</span></asp:Panel>

You have an array that is the "hash table".

In Open Hashing each cell in the array points to a list containg the collisions. The hashing has produced the same index for all items in the linked list.

In Closed Hashing you use only one array for everything. You store the collisions in the same array. The trick is to use some smart way to jump from collision to collision unitl you find what you want. And do this in a reproducible / deterministic way.

30 minutes is 30 * 60 * 1000 miliseconds. Add that to the current date to specify an expiration date 30 minutes in the future.

 var date = new Date();
 var minutes = 30;
 date.setTime(date.getTime() + (minutes * 60 * 1000));
 $.cookie("example", "foo", { expires: date });

Still surprised that no one proposed the shortest solution with align-center justify-center to center content vertically and horizontally. Check this CodeSandbox and code below:

<v-container fluid fill-height>
  <v-layout align-center justify-center>
    <v-flex>
      <!-- Some HTML elements... -->
    </v-flex>
  </v-layout>
</v-container>

>>> my_hostname = "testhostn.ame"
>>> print bool(re.match("^(([a-zA-Z]|[a-zA-Z][a-zA-Z0-9\-]*[a-zA-Z0-9])\.)*([A-Za-z]|[A-Za-z][A-Za-z0-9\-]*[A-Za-z0-9])$", my_hostname))
True
>>> my_hostname = "testhostn....ame"
>>> print bool(re.match("^(([a-zA-Z]|[a-zA-Z][a-zA-Z0-9\-]*[a-zA-Z0-9])\.)*([A-Za-z]|[A-Za-z][A-Za-z0-9\-]*[A-Za-z0-9])$", my_hostname))
False
>>> my_hostname = "testhostn.A.ame"
>>> print bool(re.match("^(([a-zA-Z]|[a-zA-Z][a-zA-Z0-9\-]*[a-zA-Z0-9])\.)*([A-Za-z]|[A-Za-z][A-Za-z0-9\-]*[A-Za-z0-9])$", my_hostname))
True

I work in a database support team with three DBAs and our considered options are:

1. Any naming standard is better than no standard.
2. There is no "one true" standard, we all have our preferences
3. If there is standard already in place, use it. Don't create another standard or muddy the existing standards.

We use singular names for tables. Tables tend to be prefixed with the name of the system (or its acronym). This is useful if the system complex as you can change the prefix to group the tables together logically (ie. reg_customer, reg_booking and regadmin_limits).

For fields we'd expect field names to be include the prefix/acryonm of the table (i.e. cust_address1) and we also prefer the use of a standard set of suffixes ( _id for the PK, _cd for "code", _nm for "name", _nb for "number", _dt for "Date").

The name of the Foriegn key field should be the same as the Primary key field.

i.e.

SELECT cust_nm, cust_add1, booking_dt
FROM reg_customer
INNER JOIN reg_booking
ON reg_customer.cust_id = reg_booking.cust_id

When developing a new project, I'd recommend you write out all the preferred entity names, prefixes and acronyms and give this document to your developers. Then, when they decide to create a new table, they can refer to the document rather than "guess" what the table and fields should be called.

Use:

try (Writer writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream("myFile.txt"), StandardCharsets.UTF_8))) {
    writer.write("text to write");
} 
catch (IOException ex) {
    // Handle me
}  

Using try() will close stream automatically. This version is short, fast (buffered) and enables choosing encoding.

This feature was introduced in Java 7.

Bloom filter: Bit array of m bits, initially all set to 0.

To add an item you run it through k hash functions that will give you k indices in the array which you then set to 1.

To check if an item is in the set, compute the k indices and check if they are all set to 1.

Of course, this gives some probability of false-positives (according to wikipedia it's about 0.61^(m/n) where n is the number of inserted items). False-negatives are not possible.

Removing an item is impossible, but you can implement counting bloom filter, represented by array of ints and increment/decrement.

Coobird's answer is the correct, complete one. However, I combined his hints with those from another site to create code that works in my app (iOS/Objective-C), which I wanted to share with anyone who comes here looking for such a thing. Please, if you like/up-vote this answer, do the same for the originals; all I did was "stand on the shoulders of giants."

As for sort-order, my technique is a modified painter's algorithm: each object has (a) an altitude of the base (I call "level") and (b) an X/Y for the "base" or "foot" of the image (examples: avatar's base is at his feet; tree's base is at it's roots; airplane's base is center-image, etc.) Then I just sort lowest to highest level, then lowest (highest on-screen) to highest base-Y, then lowest (left-most) to highest base-X. This renders the tiles the way one would expect.

Code to convert screen (point) to tile (cell) and back:

typedef struct ASIntCell {  // like CGPoint, but with int-s vice float-s
    int x;
    int y;
} ASIntCell;

// Cell-math helper here:
//      http://gamedevelopment.tutsplus.com/tutorials/creating-isometric-worlds-a-primer-for-game-developers--gamedev-6511
// Although we had to rotate the coordinates because...
// X increases NE (not SE)
// Y increases SE (not SW)
+ (ASIntCell) cellForPoint: (CGPoint) point
{
    const float halfHeight = rfcRowHeight / 2.;

    ASIntCell cell;
    cell.x = ((point.x / rfcColWidth) - ((point.y - halfHeight) / rfcRowHeight));
    cell.y = ((point.x / rfcColWidth) + ((point.y + halfHeight) / rfcRowHeight));

    return cell;
}


// Cell-math helper here:
//      http://stackoverflow.com/questions/892811/drawing-isometric-game-worlds/893063
// X increases NE,
// Y increases SE
+ (CGPoint) centerForCell: (ASIntCell) cell
{
    CGPoint result;

    result.x = (cell.x * rfcColWidth  / 2) + (cell.y * rfcColWidth  / 2);
    result.y = (cell.y * rfcRowHeight / 2) - (cell.x * rfcRowHeight / 2);

    return result;
}

<script type="text/javascript">
$(document).ready(function() {
    $('#upload').bind("click",function() 
    { 
        var imgVal = $('#uploadImage').val(); 
        if(imgVal=='') 
        { 
            alert("empty input file"); 

        } 
        return false; 

    }); 
});
</script> 

<input type="file" name="image" id="uploadImage" size="30" /> 
<input type="submit" name="upload" id="upload"  class="send_upload" value="upload" /> 

You won't face any terrible consequence, just the history will look kind of confusing.

You could change the commit message by doing

git commit --amend
git push --force-with-lease # (as opposed to --force, it doesn't overwrite others' work)

BUT this will override the remote history with yours, meaning that if anybody pulled that repo in the meanwhile, this person is going to be very mad at you...

Just do it if you are the only person accessing the repo.

Another Note: z-index must be considered when looking at children objects relative to other objects.

For example

<div class="container">
    <div class="branch_1">
        <div class="branch_1__child"></div>
    </div>
    <div class="branch_2">
        <div class="branch_2__child"></div>
    </div>
</div>

If you gave branch_1__child a z-index of 99 and you gave branch_2__child a z-index of 1, but you also gave your branch_2 a z-index of 10 and your branch_1 a z-index of 1, your branch_1__child still will not show up in front of your branch_2__child

Anyways, what I'm trying to say is; if a parent of an element you'd like to be placed in front has a lower z-index than its relative, that element will not be placed higher.

The z-index is relative to its containers. A z-index placed on a container farther up in the hierarchy basically starts a new "layer"

Incep[inception]tion

Here's a fiddle to play around:

https://jsfiddle.net/orkLx6o8/

No, you don't need to add them as a remote. That would be clumbersome and a pain to do each time.

Grabbing their commits:

git fetch [email protected]:theirusername/reponame.git theirbranch:ournameforbranch

This creates a local branch named ournameforbranch which is exactly the same as what theirbranch was for them. For the question example, the last argument would be foo:foo.

Note :ournameforbranch part can be further left off if thinking up a name that doesn't conflict with one of your own branches is bothersome. In that case, a reference called FETCH_HEAD is available. You can git log FETCH_HEAD to see their commits then do things like cherry-picked to cherry pick their commits.

Pushing it back to them:

Oftentimes, you want to fix something of theirs and push it right back. That's possible too:

git fetch [email protected]:theirusername/reponame.git theirbranch
git checkout FETCH_HEAD

# fix fix fix

git push [email protected]:theirusername/reponame.git HEAD:theirbranch

If working in detached state worries you, by all means create a branch using :ournameforbranch and replace FETCH_HEAD and HEAD above with ournameforbranch.

Here is the complete process to create a local repo and push the changes to new remote branch

1. Creating local repository:-

   Initially user may have created the local git repository.

   $ git init :- This will make the local folder as Git repository,

2. Link the remote branch:-

   Now challenge is associate the local git repository with remote master branch.

   $ git remote add RepoName RepoURL

   usage: git remote add []

3. Test the Remote

   $ git remote show --->Display the remote name

   $ git remote -v --->Display the remote branches

4. Now Push to remote

   $git add . ----> Add all the files and folder as git staged'

   $git commit -m "Your Commit Message" - - - >Commit the message

   $git push - - - - >Push the changes to the upstream

You needed to close your `<link />` 
As you can see in your <head></head> tag. This will solve your problem

<head>
    <link rel="stylesheet" href="../css/font-awesome.css" />
    <link rel="stylesheet" href="../css/font-awesome.min.css" />
</head>

If you are working on windows, you can use pywin32 (old link: see update below).

I found an example here:

import win32com.client

wmi = win32com.client.GetObject ("winmgmts:")
for usb in wmi.InstancesOf ("Win32_USBHub"):
    print usb.DeviceID

Update Apr 2020:

'pywin32' release versions from 218 and up can be found here at github. Current version 227.

NSArray *_returnedArguments = [serverOutput componentsSeparatedByString:@":"];

_returnedArguments is an array of NSStrings which the UITextField text property is expecting. No need to convert.

Syntax error:

[_appDelegate loggedIn:usernameField.text:passwordField.text:(int)[[_returnedArguments objectAtIndex:2] intValue]];

If your _appDelegate has a passwordField property, then you can set the text using the following

[[_appDelegate passwordField] setText:[_returnedArguments objectAtIndex:2]];

I committed the container into a docker image. Then I recreate another container using this docker image and the problem was gone.

You use input.files property. It's a collection of File objects and each file has a name property:

onmouseout="for (var i = 0; i < this.files.length; i++) alert(this.files[i].name);"

Try the following:

1. Unplug the usb and plug it back again.

2. Go to the Settings -> Applications -> Development of your device and uncheck the USB debugging mode and then check it back again.

3. Restart the adb on your PC. adb kill-server and then adb start-server

4. Restart your device and try again.

You need to add a name attribute to your dropdown list, then you need to add a required attribute, and then you can reference the error using myForm.[input name].$error.required:

HTML:

        <form name="myForm" ng-controller="Ctrl" ng-submit="save(myForm)" novalidate>
        <input type="text" name="txtServiceName" ng-model="ServiceName" required>
<span ng-show="myForm.txtServiceName.$error.required">Enter Service Name</span>
<br/>
          <select name="service_id" class="Sitedropdown" style="width: 220px;"          
                  ng-model="ServiceID" 
                  ng-options="service.ServiceID as service.ServiceName for service in services"
                  required> 
            <option value="">Select Service</option> 
          </select> 
          <span ng-show="myForm.service_id.$error.required">Select service</span>

        </form>

    Controller:

        function Ctrl($scope) {
          $scope.services = [
            {ServiceID: 1, ServiceName: 'Service1'},
            {ServiceID: 2, ServiceName: 'Service2'},
            {ServiceID: 3, ServiceName: 'Service3'}
          ];

    $scope.save = function(myForm) {
    console.log('Selected Value: '+ myForm.service_id.$modelValue);
    alert('Data Saved! without validate');
    };
        }

Here's a working plunker.

The following works for me:

$('video')[0].pause();

You can do it like this in other databases quite easily with a recursive query (YMMV on performance).

The other way to do it is to store two extra bits of data, a left and right value. The left and right value are derived from a pre-order traversal of the tree structure you're representing.

This is know as Modified Preorder Tree Traversal and lets you run a simple query to get all parent values at once. It also goes by the name "nested set".

i wrote this sp to create automatically the schema with all things, pk, fk, partitions, constraints... I wrote it to run in same sp.

Generally, the system should be handling view controller instantiation with a storyboard. What you want is to traverse the viewController hierarchy by grabbing a reference to the self.window.rootViewController as opposed to initializing view controllers, which should already be initialized correctly if you've setup your storyboard properly.

So, let's say your rootViewController is a UINavigationController and then you want to send something to its top view controller, you would do it like this in your AppDelegate's didFinishLaunchingWithOptions:

UINavigationController *nav = (UINavigationController *) self.window.rootViewController;
MyViewController *myVC = (MyViewController *)nav.topViewController;
myVC.data = self.data;

In Swift if would be very similar:

let nav = self.window.rootViewController as! UINavigationController;
let myVC = nav.topViewController as! MyViewController
myVc.data = self.data

You really shouldn't be initializing view controllers using storyboard id's from the app delegate unless you want to bypass the normal way storyboard is loaded and load the whole storyboard yourself. If you're having to initialize scenes from the AppDelegate you're most likely doing something wrong. I mean imagine you, for some reason, want to send data to a view controller way down the stack, the AppDelegate shouldn't be reaching way into the view controller stack to set data. That's not its business. It's business is the rootViewController. Let the rootViewController handle its own children! So, if I were bypassing the normal storyboard loading process by the system by removing references to it in the info.plist file, I would at most instantiate the rootViewController using instantiateViewControllerWithIdentifier:, and possibly its root if it is a container, like a UINavigationController. What you want to avoid is instantiating view controllers that have already been instantiated by the storyboard. This is a problem I see a lot. In short, I disagree with the accepted answer. It is incorrect unless the posters means to remove loading of the storyboard from the info.plist since you will have loaded 2 storyboards otherwise, which makes no sense. It's probably not a memory leak because the system initialized the root scene and assigned it to the window, but then you came along and instantiated it again and assigned it again. Your app is off to a pretty bad start!

I was never able to get this to work simple using annotations. To get it to work, I created a ContextResolver for ObjectMapper, then I added the JSR310Module (update: now it is JavaTimeModule instead), along with one more caveat, which was the need to set write-date-as-timestamp to false. See more at the documentation for the JSR310 module. Here's an example of what I used.

Dependency

<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jsr310</artifactId>
    <version>2.4.0</version>
</dependency>

^{Note: One problem I faced with this is that the jackson-annotation version pulled in by another dependency, used version 2.3.2, which cancelled out the 2.4 required by the jsr310. What happened was I got a NoClassDefFound for ObjectIdResolver, which is a 2.4 class. So I just needed to line up the included dependency versions}

ContextResolver

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.datatype.jsr310.JSR310Module;
import javax.ws.rs.ext.ContextResolver;
import javax.ws.rs.ext.Provider;

@Provider
public class ObjectMapperContextResolver implements ContextResolver<ObjectMapper> {  
    private final ObjectMapper MAPPER;

    public ObjectMapperContextResolver() {
        MAPPER = new ObjectMapper();
        // Now you should use JavaTimeModule instead
        MAPPER.registerModule(new JSR310Module());
        MAPPER.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
    }

    @Override
    public ObjectMapper getContext(Class<?> type) {
        return MAPPER;
    }  
}

Resource class

@Path("person")
public class LocalDateResource {

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public Response getPerson() {
        Person person = new Person();
        person.birthDate = LocalDate.now();
        return Response.ok(person).build();
    }

    @POST
    @Consumes(MediaType.APPLICATION_JSON)
    public Response createPerson(Person person) {
        return Response.ok(
                DateTimeFormatter.ISO_DATE.format(person.birthDate)).build();
    }

    public static class Person {
        public LocalDate birthDate;
    }
}

Test

curl -v http://localhost:8080/api/person
Result: {"birthDate":"2015-03-01"}

curl -v -POST -H "Content-Type:application/json" -d "{\"birthDate\":\"2015-03-01\"}" http://localhost:8080/api/person
Result: 2015-03-01

See also here for JAXB solution.

UPDATE

The JSR310Module is deprecated as of version 2.7 of Jackson. Instead, you should register the module JavaTimeModule. It is still the same dependency.

This should work for SQL Server:

SELECT * FROM myTable
WHERE month = DATEPART(m, GETDATE()) AND
year = DATEPART(yyyy, GETDATE())

It's exactly what the error says. You didn't create any RestTemplate bean, so it can't autowire any. If you need a RestTemplate you'll have to provide one. For example, add the following to TestMicroServiceApplication.java:

@Bean
public RestTemplate restTemplate() {
    return new RestTemplate();
}

Note, in earlier versions of the Spring cloud starter for Eureka, a RestTemplate bean was created for you, but this is no longer true.

What the provided links to comparisons/animations do not consider is when the amount of data exceed available memory --- at which point the number of passes over the data, i.e. I/O-costs, dominate the runtime. If you need to do that, read up on "external sorting" which usually cover variants of merge- and heap sorts.

http://corte.si/posts/code/visualisingsorting/index.html and http://corte.si/posts/code/timsort/index.html also have some cool images comparing various sorting algorithms.

your excel file's extension change to xml. And open it in notepad. password text find in xml file.

you see like below line;

(sorry for my bad english)

in addition to all the answers that other friends have , if somebody who is looking this post is looking for a way to delete a "Folder" not a "file" , should take care that Folders must delete by php rmdir() function and if u want to delete a "Folder" by unlink() , u will encounter with a wrong Warning message that says "permission denied"

however u can make folders & files by mkdir() but the way u delete folders (rmdir()) is different from the way you delete files(unlink())

eventually as a fact:

in many programming languages, any permission related error may not directly means an actual permission issue

for example, if you want to readSync a file that doesn't exist with node fs module you will encounter a wrong EPERM error

If you use unicorn.

Look at top on your server. Unicorn likely is using 100% of CPU right now. There are several reasons of this problem.

• You should check your HTTP requests, some of their can be very hard.

• Check unicorn's version. May be you've updated it recently, and something was broken.

Late to the party here, but I often use this construct for doing ad-hoc padding of some value n, known to be a positive, decimal:

(offset + n + '').substr(1);

Where offset is 10^^digits.

E.g. Padding to 5 digits, where n = 123:

(1e5 + 123 + '').substr(1); // => 00123

The hexidecimal version of this is slightly more verbose:

(0x100000 + 0x123).toString(16).substr(1); // => 00123

Note 1: I like @profitehlolz's solution as well, which is the string version of this, using slice()'s nifty negative-index feature.

It works!

decimal moneyvalue = 1921.39m; 
string html = String.Format("Order Total: {0:C}", moneyvalue); 
Console.WriteLine(html);

Output

Order Total: $1,921.39

In short, to do modification on the list while iterating the same list.

list[:] = ["Modify the list" for each_element in list "Condition Check"]

example:

list[:] = [list.remove(each_element) for each_element in list if each_element in ["data1", "data2"]]

I just found my own solution to this problem, or at least my problem.
I was using justify-content: space-around instead of justify-content: space-between;.

This way the end elements will stick to the top and bottom, and you could have custom margins if you wanted.

Use CTRL+D at each line and it will find the matching words and select them then you can use multiple cursors.

You can also use find to find all the occurrences and then it would be multiple cursors too.

I know this is an old Question

But in case you want to do it programmatically or the java way

For Image Backgrounds; you can use BackgroundImage class

BackgroundImage myBI= new BackgroundImage(new Image("my url",32,32,false,true),
        BackgroundRepeat.REPEAT, BackgroundRepeat.NO_REPEAT, BackgroundPosition.DEFAULT,
          BackgroundSize.DEFAULT);
//then you set to your node
myContainer.setBackground(new Background(myBI));

For Paint or Fill Backgrounds; you can use BackgroundFill class

BackgroundFill myBF = new BackgroundFill(Color.BLUEVIOLET, new CornerRadii(1),
         new Insets(0.0,0.0,0.0,0.0));// or null for the padding
//then you set to your node or container or layout
myContainer.setBackground(new Background(myBF));

Keeps your java alive && your css dead..

If you're trying to just count how many of your cells in a range are not blank try this:

=COUNTA(range)

Example: (assume that it starts from A1 downwards):

---------    
Something 
---------
Something
---------

---------
Something
---------

---------
Something
---------

=COUNTA(A1:A6) returns 4 since there are two blank cells in there.

If you wish to use postman the right way is to use the headers as such

key: Authorization

value: jwt {token}

as simple as that.
