You don't need the separate fill item. In fact, it's invalid. You just have to add a solid block to the shape. The subsequent stroke draws on top of the solid:

<shape 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:shape="rectangle">

    <corners android:radius="5dp" />
    <solid android:color="@android:color/white" />
    <stroke
        android:width="1dip"
        android:color="@color/bggrey" />
</shape>

You also don't need the layer-list if you only have one shape.

With a Maven version of 3.5 or higher, you should be able to use a placeholder (e.g. ${revision}) in the parent section and inside the rest of the pom, you can use ${project.version}.

Actually, you can also omit project properties outside of parent which are the same, as they will be inherited. The result would look something like this:

<project>
    <parent>
    <artifactId>build.parent</artifactId>
    <groupId>company</groupId>
    <relativePath>../build.parent/pom.xml</relativePath>
    <version>${revision}</version>  <!-- use placeholder -->
    </parent>

    <modelVersion>4.0.0</modelVersion>
    <artifactId>artifact</artifactId>
    <!-- no 'version', no 'groupId'; inherited from parent -->
    <packaging>eclipse-plugin</packaging>

    ...
</project>

For more information, especially on how to resolve the placeholder during publishing, see Maven CI Friendly Versions | Multi Module Setup.

The problem could be due to too many users accessing the db at the same time. Either increase number of users that can concurrently access the db or kick out existing users (or apps). Use "Show processlist;" in the host DB to check connected users;

I came across another reason, catalina.policy file, could prohibit accessing specific IP/PORT

You can't, you'll have to do something like

<script type="text/javascript">
   var php_var = "<?php echo $php_var; ?>";
</script>

You can also load it with AJAX

rhino is right, the snippet lacks of a type for the sake of brevity.

Also, note that if $php_var has quotes, it will break your script. You shall use addslashes, htmlentities or a custom function.

Why don't you simply try

System.out.println(1500/1000.0);
System.out.println(500/1000.0);

Yes it's possible, look for 9-patch on google. Good articles :

You can also get BLOB object directly from XMLHttpRequest. Setting responseType to blob makes the trick. Here is my code:

var xhr = new XMLHttpRequest();
xhr.open("GET", "http://localhost/image.jpg");
xhr.responseType = "blob";
xhr.onload = response;
xhr.send();

And the response function looks like this:

function response(e) {
   var urlCreator = window.URL || window.webkitURL;
   var imageUrl = urlCreator.createObjectURL(this.response);
   document.querySelector("#image").src = imageUrl;
}

We just have to make an empty image element in HTML:

<img id="image"/>

Seems the SMTP as internet standard uses only reliable Transport protocol. RFC821 has TCP, NCP, NITS as examples!

Pretty much. One small difference though: if the Task fails, GetResult() will just throw the exception caused directly, while Task.Result will throw an AggregateException. However, what's the point of using either of those when it's async? The 100x better option is to use await.

Also, you're not meant to use GetResult(). It's meant to be for compiler use only, not for you. But if you don't want the annoying AggregateException, use it.

Just call fig.tight_layout() as you normally would. (pyplot is just a convenience wrapper. In most cases, you only use it to quickly generate figure and axes objects and then call their methods directly.)

There shouldn't be a difference between the QtAgg backend and the default backend (or if there is, it's a bug).

E.g.

import matplotlib.pyplot as plt

#-- In your case, you'd do something more like:
# from matplotlib.figure import Figure
# fig = Figure()
#-- ...but we want to use it interactive for a quick example, so 
#--    we'll do it this way
fig, axes = plt.subplots(nrows=4, ncols=4)

for i, ax in enumerate(axes.flat, start=1):
    ax.set_title('Test Axes {}'.format(i))
    ax.set_xlabel('X axis')
    ax.set_ylabel('Y axis')

plt.show()

Before Tight Layout

After Tight Layout

import matplotlib.pyplot as plt

fig, axes = plt.subplots(nrows=4, ncols=4)

for i, ax in enumerate(axes.flat, start=1):
    ax.set_title('Test Axes {}'.format(i))
    ax.set_xlabel('X axis')
    ax.set_ylabel('Y axis')

fig.tight_layout()

plt.show()

Use console.log(JSON.stringify(result)) to get the JSON in a string format.

EDIT: If your intention is to get the id and other properties from the result object and you want to see it console to know if its there then you can check with hasOwnProperty and access the property if it does exist:

var obj = {id : "007", name : "James Bond"};
console.log(obj);                    // Object { id: "007", name: "James Bond" }
console.log(JSON.stringify(obj));    //{"id":"007","name":"James Bond"}
if (obj.hasOwnProperty("id")){
    console.log(obj.id);             //007
}

I tried from ubuntu terminal and I don't know why the GUI didn't show up according to tttthomasssss answer. So I followed the comment from KLDavenport and it worked. Here is the summary:

Open your terminal/command-line and type python then

>>> import nltk .>>> nltk.download("stopwords")

This will store the stopwords corpus under the nltk_data. For my case it was /home/myusername/nltk_data/corpora/stopwords.

If you need another corpus then visit nltk data and find the corpus with their ID. Then use the ID to download like we did for stopwords.

use .val(), it will return the value of the <input>

$("#spa").val().length > 0

And you had a typo, length not lenght.

To create all intermediate-level destination directories you could use os.makedirs() before copying:

import os
import shutil

srcfile = 'a/long/long/path/to/file.py'
dstroot = '/home/myhome/new_folder'


assert not os.path.isabs(srcfile)
dstdir =  os.path.join(dstroot, os.path.dirname(srcfile))

os.makedirs(dstdir) # create all directories, raise an error if it already exists
shutil.copy(srcfile, dstdir)

The download from java.com which installs in /Library/Internet Plug-Ins is only the JRE, for development you probably want to download the JDK from http://www.oracle.com/technetwork/java/javase/downloads/index.html and install that instead. This will install the JDK at /Library/Java/JavaVirtualMachines/jdk1.7.0_<something>.jdk/Contents/Home which you can then add to Eclipse via Preferences -> Java -> Installed JREs.

I've been searching for an IMAP solution for a while now, and after trying quite a few, I'm going with AE.Net.Mail.

You can download the code by going to the Code tab and click the small 'Download' icon. As the author does not provide any pre-built downloads, you must compile it yourself. (I believe you can get it through NuGet though). There is no longer a .dll in the bin/ folder.

There is no documentation, which I consider a downside, but I was able to whip this up by looking at the source code (yay for open source!) and using Intellisense. The below code connects specifically to Gmail's IMAP server:

// Connect to the IMAP server. The 'true' parameter specifies to use SSL
// which is important (for Gmail at least)
ImapClient ic = new ImapClient("imap.gmail.com", "[email protected]", "pass",
                ImapClient.AuthMethods.Login, 993, true);
// Select a mailbox. Case-insensitive
ic.SelectMailbox("INBOX");
Console.WriteLine(ic.GetMessageCount());
// Get the first *11* messages. 0 is the first message;
// and it also includes the 10th message, which is really the eleventh ;)
// MailMessage represents, well, a message in your mailbox
MailMessage[] mm = ic.GetMessages(0, 10);
foreach (MailMessage m in mm)
{
    Console.WriteLine(m.Subject);
}
// Probably wiser to use a using statement
ic.Dispose();

Make sure you checkout the Github page for the newest version and some better code examples.

You should be able to create a customize UI button programmatically by accessing the titleLabel property of UIButton.

Per Class Reference in Swift: Regarding the titleLabel property, it says that "although this property is read-only, its own properties are read/write. Use these properties primarily to configure the text of the button."

In Swift, you can directly modify the properties of titleLabel like such:

let myFirstButton = UIButton()
myFirstButton.titleLabel!.text = "I made a label on the screen #toogood4you"
myFirstButton.titleLabel!.font = UIFont(name: "MarkerFelt-Thin", size: 45)
myFirstButton.titleLabel!.textColor = UIColor.red
myFirstButton.titleLabel!.textAlignment = .center
myFirstButton.titleLabel!.numberOfLines = 5
myFirstButton.titleLabel!.frame = CGRect(x: 15, y: 54, width: 300, height: 500)

Edit

Swift 3.1 Syntax

There is an underlying buffer/stream that getchar() and friends read from. When you enter text, the text is stored in a buffer somewhere. getchar() can stream through it one character at a time. Each read returns the next character until it reaches the end of the buffer. The reason it's not asking you for subsequent characters is that it can fetch the next one from the buffer.

If you run your script and type directly into it, it will continue to prompt you for input until you press CTRL+D (end of file). If you call it like ./program < myInput where myInput is a text file with some data, it will get the EOF when it reaches the end of the input. EOF isn't a character that exists in the stream, but a sentinel value to indicate when the end of the input has been reached.

As an extra warning, I believe getchar() will also return EOF if it encounters an error, so you'll want to check ferror(). Example below (not tested, but you get the idea).

main() {
    int c;
    do {
        c = getchar();
        if (c == EOF && ferror()) {
            perror("getchar");
        }
        else {
            putchar(c);
        }
    }
    while(c != EOF);
}

My version of the answer is actually very similar to the @Stefan Haustein. I found the answer on Android Developer page Retrieving File Information; the information here is even more condensed on this specific topic than on Storage Access Framework guide site. In the result from the query the column index containing file name is OpenableColumns.DISPLAY_NAME. None of other answers/solutions for column indexes worked for me. Below is the sample function:

 /**
 * @param uri uri of file.
 * @param contentResolver access to server app.
 * @return the name of the file.
 */
def extractFileName(uri: Uri, contentResolver: ContentResolver): Option[String] = {

    var fileName: Option[String] = None
    if (uri.getScheme.equals("file")) {

        fileName = Option(uri.getLastPathSegment)
    } else if (uri.getScheme.equals("content")) {

        var cursor: Cursor = null
        try {

            // Query the server app to get the file's display name and size.
            cursor = contentResolver.query(uri, null, null, null, null)

            // Get the column indexes of the data in the Cursor,
            // move to the first row in the Cursor, get the data.
            if (cursor != null && cursor.moveToFirst()) {

                val nameIndex = cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME)
                fileName = Option(cursor.getString(nameIndex))
            }

        } finally {

            if (cursor != null) {
                cursor.close()
            }

        }

    }

    fileName
}

If Condition to check, currently class active or not

$('#next').click(function(){
    if($('p:last').hasClass('active'){
       $('.active').removeClass();
    }else{
       $('.active').addClass();
    }
});

final ListView lv = (ListView) findViewById(R.id.ListView01);

lv.setOnItemClickListener(new OnItemClickListener() {
      public void onItemClick(AdapterView<?> myAdapter, View myView, int myItemInt, long mylng) {
        String selectedFromList =(String) (lv.getItemAtPosition(myItemInt));

      }                 
});

I hope this fixes your problem.

The outcome sql will be different but the result should be the same:

var shifts = Shifts.Where(s => !EmployeeShifts.Where(es => es.ShiftID == s.ShiftID).Any());

In python, when you have an iterable, usually you iterate without an index:

letters = 'abcdef' # or a list, tupple or other iterable
for l in letters:
    print(l)

If you need to traverse the iterable in reverse order, you would do:

for l in letters[::-1]:
    print(l)

When for any reason you need the index, you can use enumerate:

for i, l in enumerate(letters, start=1): #start is 0 by default
    print(i,l)

You can enumerate in reverse order too...

for i, l in enumerate(letters[::-1])
    print(i,l)

ON ANOTHER NOTE...

Usually when we traverse an iterable we do it to apply the same procedure or function to each element. In these cases, it is better to use map:

If we need to capitilize each letter:

map(str.upper, letters)

Or get the Unicode code of each letter:

map(ord, letters)

Try to create a function which uses recursion. Your DateTime object is an input and function returns a new DateTime object which stands for the beginning of the week.

    DateTime WeekBeginning(DateTime input)
    {
        do
        {
            if (input.DayOfWeek.ToString() == "Monday")
                return input;
            else
                return WeekBeginning(input.AddDays(-1));
        } while (input.DayOfWeek.ToString() == "Monday");
    }

I faced the exact problem when creating a new project, It seams to be related to the Appcompat Library to solve it:

I replaced : implementation 'com.android.support:appcompat-v7:28.0.0-alpha3' by implementation 'com.android.support:appcompat-v7:27.1.1' And everything worked fine.

In conclusion, The problem is related to a bug in the library version.

But if it is necessary to use the Natesh bhat's solution is for you.

word-wrap: break-word; 

add this to your container that should do the trick

One of the benefits is that Razor views can be rendered inside unit tests, this is something that was not easily possible with the previous ASP.Net renderer.

From ScottGu's announcement this is listed as one of the design goals:

Unit Testable: The new view engine implementation will support the ability to unit test views (without requiring a controller or web-server, and can be hosted in any unit test project – no special app-domain required).

It has to do with the general workflow of Git. You're unlikely to be able to push directly to the main project's repository. I'm not sure if GitHub project's repository support branch-based access control, as you wouldn't want to grant anyone the permission to push to the master branch for example.

The general pattern is as follows:

• Fork the original project's repository to have your own GitHub copy, to which you'll then be allowed to push changes.
• Clone your GitHub repository onto your local machine
• Optionally, add the original repository as an additional remote repository on your local repository. You'll then be able to fetch changes published in that repository directly.
• Make your modifications and your own commits locally.
• Push your changes to your GitHub repository (as you generally won't have the write permissions on the project's repository directly).
• Contact the project's maintainers and ask them to fetch your changes and review/merge, and let them push back to the project's repository (if you and them want to).

Without this, it's quite unusual for public projects to let anyone push their own commits directly.

Let's say that you have a folder named "contollers".

In your app.js you can put this code:

console.log("Loading controllers....");
var controllers = {};

var controllers_path = process.cwd() + '/controllers'

fs.readdirSync(controllers_path).forEach(function (file) {
    if (file.indexOf('.js') != -1) {
        controllers[file.split('.')[0]] = require(controllers_path + '/' + file)
    }
});

console.log("Controllers loaded..............[ok]");

... and ...

router.get('/ping', controllers.ping.pinging);

in your controllers forlder you will have the file "ping.js" with this code:

exports.pinging = function(req, res, next){
    console.log("ping ...");
}

And this is it....

You were on the right track. IrfanView sets the background for transparency the same as the viewing color around the image.

You just need to re-open the image with IrfanView after changing the view color to white.

To change the viewing color in Irfanview go to:

Options > Properties/Settings > Viewing > Main window color

"How to attach url link to an image?"

You do it like this:

<a href="http://www.google.com"><img src="http://www.google.com/intl/en_ALL/images/logo.gif"/></a>

Swift 3:

Set button title:

//for normal state:
my_btn.setTitle("Button Title", for: .normal)

// For highlighted state:
my_btn.setTitle("Button Title2", for: .highlighted)

pgrep -f <your process name> | xargs kill -9

This will kill the your process service. In my case it is

pgrep -f python | xargs kill -9

Use the DecimalFormat class to format the double

How about check and then set dict element without processing all indexes twice?

Solution:

def nested_yield(nested, keys_list):
    """
    Get current nested data by send(None) method. Allows change it to Value by calling send(Value) next time
    :param nested: list or dict of lists or dicts
    :param keys_list: list of indexes/keys
    """
    if not len(keys_list):  # assign to 1st level list
        if isinstance(nested, list):
            while True:
                nested[:] = yield nested
        else:
            raise IndexError('Only lists can take element without key')


    last_key = keys_list.pop()
    for key in keys_list:
        nested = nested[key]

    while True:
        try:
            nested[last_key] = yield nested[last_key]
        except IndexError as e:
            print('no index {} in {}'.format(last_key, nested))
            yield None

Example workflow:

ny = nested_yield(nested_dict, nested_address)
data_element = ny.send(None)
if data_element:
    # process element
    ...
else:
    # extend/update nested data
    ny.send(new_data_element)
    ...
ny.close()

Test

>>> cfg= {'Options': [[1,[0]],[2,[4,[8,16]]],[3,[9]]]}
    ny = nested_yield(cfg, ['Options',1,1,1])
    ny.send(None)
[8, 16]
>>> ny.send('Hello!')
'Hello!'
>>> cfg
{'Options': [[1, [0]], [2, [4, 'Hello!']], [3, [9]]]}
>>> ny.close()

To further work with array of maps, the followings could help:

@RequestMapping(value = "/process", method = RequestMethod.POST, headers = "Accept=application/json")
public void setLead(@RequestBody Collection<? extends Map<String, Object>> payload) throws Exception {

  List<Map<String,Object>> maps = new ArrayList<Map<String,Object>>();
  maps.addAll(payload);

}

To remove any doubt, my solution was to make a deep copy of the slice instead of a regular copy. This may not be applicable depending on your context (Memory constraints / size of the slice, potential for performance degradation - especially if the copy occurs in a loop like it did for me, etc...)

To be clear, here is the warning I received:

/opt/anaconda3/lib/python3.6/site-packages/ipykernel/__main__.py:54:
SettingWithCopyWarning: A value is trying to be set on a copy of a slice from a DataFrame
See the caveats in the documentation:
http://pandas.pydata.org/pandas-docs/stable/indexing.html#indexing-view-versus-copy

Illustration

I had doubts that the warning was thrown because of a column I was dropping on a copy of the slice. While not technically trying to set a value in the copy of the slice, that was still a modification of the copy of the slice. Below are the (simplified) steps I have taken to confirm the suspicion, I hope it will help those of us who are trying to understand the warning.

Example 1: dropping a column on the original affects the copy

We knew that already but this is a healthy reminder. This is NOT what the warning is about.

>> data1 = {'A': [111, 112, 113], 'B':[121, 122, 123]}
>> df1 = pd.DataFrame(data1)
>> df1

    A   B
0   111 121
1   112 122
2   113 123


>> df2 = df1
>> df2

A   B
0   111 121
1   112 122
2   113 123

# Dropping a column on df1 affects df2
>> df1.drop('A', axis=1, inplace=True)
>> df2
    B
0   121
1   122
2   123

It is possible to avoid changes made on df1 to affect df2. Note: you can avoid importing copy.deepcopy by doing df.copy() instead.

>> data1 = {'A': [111, 112, 113], 'B':[121, 122, 123]}
>> df1 = pd.DataFrame(data1)
>> df1

A   B
0   111 121
1   112 122
2   113 123

>> import copy
>> df2 = copy.deepcopy(df1)
>> df2
A   B
0   111 121
1   112 122
2   113 123

# Dropping a column on df1 does not affect df2
>> df1.drop('A', axis=1, inplace=True)
>> df2
    A   B
0   111 121
1   112 122
2   113 123

Example 2: dropping a column on the copy may affect the original

This actually illustrates the warning.

>> data1 = {'A': [111, 112, 113], 'B':[121, 122, 123]}
>> df1 = pd.DataFrame(data1)
>> df1

    A   B
0   111 121
1   112 122
2   113 123

>> df2 = df1
>> df2

    A   B
0   111 121
1   112 122
2   113 123

# Dropping a column on df2 can affect df1
# No slice involved here, but I believe the principle remains the same?
# Let me know if not
>> df2.drop('A', axis=1, inplace=True)
>> df1

B
0   121
1   122
2   123

It is possible to avoid changes made on df2 to affect df1

>> data1 = {'A': [111, 112, 113], 'B':[121, 122, 123]}
>> df1 = pd.DataFrame(data1)
>> df1

    A   B
0   111 121
1   112 122
2   113 123

>> import copy
>> df2 = copy.deepcopy(df1)
>> df2

A   B
0   111 121
1   112 122
2   113 123

>> df2.drop('A', axis=1, inplace=True)
>> df1

A   B
0   111 121
1   112 122
2   113 123

Cheers!

Installing Build-Tools 23.0.1 instead of 23.0.2 fixed this issue for me.

The ggrepel package works great for repelling overlapping text labels away from each other. You can use either geom_label_repel() (draws rectangles around the text) or geom_text_repel() functions.

In a very simple way I'm taking the example of the Facebook timeline.

Case 1: When you post something on your timeline, it's a fresh new entry. So in this case they use the POST method because the POST method is non-idempotent.

Case 2: If your friend comment on your post the first time, that also will create a new entry in the database so the POST method used.

Case 3: If your friend edits his comment, in this case, they had a comment id, so they will update an existing comment instead of creating a new entry in the database. Therefore for this type of operation use the PUT method because it is idempotent.*

In a single line, use POST to add a new entry in the database and PUT to update something in the database.

The "==" operator returns true only if the two references pointing to the same object in memory. The equals() method on the other hand returns true based on the contents of the object.

Example:

String personalLoan = new String("cheap personal loans");
String homeLoan = new String("cheap personal loans");

//since two strings are different object result should be false
boolean result = personalLoan == homeLoan;
System.out.println("Comparing two strings with == operator: " + result);

//since strings contains same content , equals() should return true
result = personalLoan.equals(homeLoan);
System.out.println("Comparing two Strings with same content using equals method: " + result);

homeLoan = personalLoan;
//since both homeLoan and personalLoan reference variable are pointing to same object
//"==" should return true
result = (personalLoan == homeLoan);
System.out.println("Comparing two reference pointing to same String with == operator: " + result);

Output: Comparing two strings with == operator: false Comparing two Strings with same content using equals method: true Comparing two references pointing to same String with == operator: true

You can also get more details from the link: http://javarevisited.blogspot.in/2012/12/difference-between-equals-method-and-equality-operator-java.html?m=1

If you go the INSERT VALUES route to insert multiple rows, make sure to delimit the VALUES into sets using parentheses, so:

INSERT INTO `receiving_table`
  (id,
  first_name,
  last_name)
VALUES 
  (1002,'Charles','Babbage'),
  (1003,'George', 'Boole'),
  (1001,'Donald','Chamberlin'),
  (1004,'Alan','Turing'),
  (1005,'My','Widenius');

Otherwise MySQL objects that "Column count doesn't match value count at row 1", and you end up writing a trivial post when you finally figure out what to do about it.

With the background-size property in those browsers which support this very new feature of CSS.

I spent quite a lot of time figuring out how to do this in Intellij 13x. I apparently never added the properties files to the artifacts that required them, which is a separate step in Intellij. The setup below also works when you have a properties file that is shared by multiple modules.

• Go to your project setup (CTRL + ALT + SHIFT + S)
• In the list, select the module that you want to add one or more properties files to.
• On the right, select the Dependencies tab.
• Click the green plus and select "Jars or directories".
• Now select the folder that contains the property file(s). (I haven't tried including an individual file)
• Intellij will now ask you what the "category" of the selected file is. Choose "classes" (even though they are not).
• Now you must add the properties files to the artifact. Intellij will give you the shortcut shown below. It will show errors in the red part at the bottom and a 'red lightbulb' that when clicked shows you an option to add the files to the artifact. You can also go to the 'artifacts' section and add the files to the artifacts manually.

When nginx returns 400(bad request) it will log the reason into error log, at "info" level and take a look into error log when testing.

When top_k<<axis_length,it better than argsort.

import numpy as np

def get_sorted_top_k(array, top_k=1, axis=-1, reverse=False):
    if reverse:
        axis_length = array.shape[axis]
        partition_index = np.take(np.argpartition(array, kth=-top_k, axis=axis),
                                  range(axis_length - top_k, axis_length), axis)
    else:
        partition_index = np.take(np.argpartition(array, kth=top_k, axis=axis), range(0, top_k), axis)
    top_scores = np.take_along_axis(array, partition_index, axis)
    # resort partition
    sorted_index = np.argsort(top_scores, axis=axis)
    if reverse:
        sorted_index = np.flip(sorted_index, axis=axis)
    top_sorted_scores = np.take_along_axis(top_scores, sorted_index, axis)
    top_sorted_indexes = np.take_along_axis(partition_index, sorted_index, axis)
    return top_sorted_scores, top_sorted_indexes

if __name__ == "__main__":
    import time
    from sklearn.metrics.pairwise import cosine_similarity

    x = np.random.rand(10, 128)
    y = np.random.rand(1000000, 128)
    z = cosine_similarity(x, y)
    start_time = time.time()
    sorted_index_1 = get_sorted_top_k(z, top_k=3, axis=1, reverse=True)[1]
    print(time.time() - start_time)

You get that because you're trying to get a key from a dictionary when it's not there. You need to test if it is in there first.

try:

is_private = 'is_private' in request.POST

or

is_private = 'is_private' in request.POST and request.POST['is_private']

depending on the values you're using.

Even if my answer wont be accepted as the correct answer, I just feel all these answers above caused me to have more problems here is how I fixed it

1. Get Sublime Text (crazy, right? No, just follow my steps)
2. Click on file and select open folder, then choose the folder of the project you are working on
3. Now click on Find from the Tabs, and select find in files or just do Ctrl + Shift + F (for Windows users, for mac users you already know the drill)
4. Now copy and paste exactly the name of the package you want to change in the Find section and paste in the replace section what you would like to replace the package name with.
5. Click on FIND (do not click on REPLACE just yet).
6. Now clicking on Find lists all available package name in your project which matches your search criteria, if you are satisfied with this then repeat from no. 3 but this time click on REPLACE.
7. Rebuild your project and have fun

Conclusion: a simple find and replace program is all you need to sort this problem out, and I strongly recommend Sublime Text 3 for that.

With the magic of user-defined literals, we have yet another solution to this. C++14 added a std::string literal operator.

using namespace std::string_literals;
auto const x = "\0" "0"s;

Constructs a string of length 2, with a '\0' character (null) followed by a '0' character (the digit zero). I am not sure if it is more or less clear than the initializer_list<char> constructor approach, but it at least gets rid of the ' and , characters.

The answers on here are specific to using the custom UI Editor. I spent some time creating the interface without that wonderful program, so I am documenting the solution here to help anyone else decide if they need that custom UI editor or not.

I came across the following microsoft help webpage - https://msdn.microsoft.com/en-us/library/office/ff861787.aspx. This shows how to set up the interface manually, but I had some trouble when pointing to my custom add-in code.

To get the buttons to work with your custom macros, setup the macro in your .xlam subs to be called as described in this SO answer - Calling an excel macro from the ribbon. Basically, you'll need to add that "control As IRibbonControl" paramter to any module pointed from your ribbon xml. Also, your ribbon xml should have the onAction="myaddin!mymodule.mysub" syntax to properly call any modules loaded by the add in.

Using those instructions I was able to create an excel add in (.xlam file) that has a custom tab loaded when my VBA gets loaded into Excel along with the add in. The buttons execute code from the add in and the custom tab uninstalls when I remove the add in.

by splitting with newlines.

for line in wallop_of_a_string_with_many_lines.split('\n'):
  #do_something..

if you iterate over a string, you are iterating char by char in that string, not by line.

>>>string = 'abc'
>>>for line in string:
    print line

a
b
c

Use CultureInfo class to change your culture info.

var dutchCultureInfo = CultureInfo.CreateSpecificCulture("nl-NL");
var date1 = DateTime.ParseExact(date, "dd.MM.yyyy HH:mm:ss", dutchCultureInfo);

There is a pretty good example on https://developers.google.com/maps/documentation/javascript/examples/geocoding-simple

To shorten it up a little:

geocoder = new google.maps.Geocoder();

function codeAddress() {

    //In this case it gets the address from an element on the page, but obviously you  could just pass it to the method instead
    var address = document.getElementById( 'address' ).value;

    geocoder.geocode( { 'address' : address }, function( results, status ) {
        if( status == google.maps.GeocoderStatus.OK ) {

            //In this case it creates a marker, but you can get the lat and lng from the location.LatLng
            map.setCenter( results[0].geometry.location );
            var marker = new google.maps.Marker( {
                map     : map,
                position: results[0].geometry.location
            } );
        } else {
            alert( 'Geocode was not successful for the following reason: ' + status );
        }
    } );
}

This is what works for me.

tar -cvf my_dir.tar.gz -C /my_dir/ $(find /my_dir/ -maxdepth 1 -printf '%P ')

You could also use

tar -cvf my_dir.tar.gz -C /my_dir/ $(find /my_dir/ -mindepth 1 -maxdepth 1 -printf '%P ')

In the first command, find returns a list of files and sub-directories of my_dir. However, the directory my_dir is itself included in that list as '.' The -printf parameter removes the full path including that '.' and also all crlf However the space in the format string '%P ' of printf leaves a remnant in the list of files and sub-directories of my_dir and can be seen by a leading space in the result of the find command.

That will not be a problem for TAR but if you want to fix this, add -mindepth 1 as in the second command.

map creates a new list by applying a function to every element of the source:

xs = [1, 2, 3]

# all of those are equivalent — the output is [2, 4, 6]
# 1. map
ys = map(lambda x: x * 2, xs)
# 2. list comprehension
ys = [x * 2 for x in xs]
# 3. explicit loop
ys = []
for x in xs:
    ys.append(x * 2)

n-ary map is equivalent to zipping input iterables together and then applying the transformation function on every element of that intermediate zipped list. It's not a Cartesian product:

xs = [1, 2, 3]
ys = [2, 4, 6]

def f(x, y):
    return (x * 2, y // 2)

# output: [(2, 1), (4, 2), (6, 3)]
# 1. map
zs = map(f, xs, ys)
# 2. list comp
zs = [f(x, y) for x, y in zip(xs, ys)]
# 3. explicit loop
zs = []
for x, y in zip(xs, ys):
    zs.append(f(x, y))

I've used zip here, but map behaviour actually differs slightly when iterables aren't the same size — as noted in its documentation, it extends iterables to contain None.

you should add charset=UTF-8 in meta tag and use json_encode for special characters

json_encode function converts special characters in UTF8 standard

Changing the distribution of any function to another involves using the inverse of the function you want.

In other words, if you aim for a specific probability function p(x) you get the distribution by integrating over it -> d(x) = integral(p(x)) and use its inverse: Inv(d(x)). Now use the random probability function (which have uniform distribution) and cast the result value through the function Inv(d(x)). You should get random values cast with distribution according to the function you chose.

This is the generic math approach - by using it you can now choose any probability or distribution function you have as long as it have inverse or good inverse approximation.

Hope this helped and thanks for the small remark about using the distribution and not the probability itself.

It seems to me, that it is by design that this file is empty.

A similar question has been asked here: https://stackoverflow.com/questions/2567432/ubuntu-apache-httpd-conf-or-apache2-conf

Throw preserves the stack trace. So lets say Source1 throws Error1 , its caught by Source2 and Source2 says throw then Source1 Error + Source2 Error will be available in the stack trace.

Throw ex does not preserve the stack trace. So all errors of Source1 will be wiped out and only Source2 error will sent to the client.

Sometimes just reading things are not clear , would suggest to watch this video demo to get more clarity , Throw vs Throw ex in C#.

For MariaDB users (version >= 10.2.2) and MySQL (version >= 5.7), the simple solution is:

ALTER TABLE `table` ROW_FORMAT=DYNAMIC;

Interface are nothing but a pure abstract class in C++. Ideally this interface class should contain only pure virtual public methods and static const data. For example:

class InterfaceA
{
public:
  static const int X = 10;

  virtual void Foo() = 0;
  virtual int Get() const = 0;
  virtual inline ~InterfaceA() = 0;
};
InterfaceA::~InterfaceA () {}

<property name="cronExpression" value="0 0/30 * * * ?" />

Option 1: Insert -> Update

If you like to avoid both changes()=0 and INSERT OR IGNORE even if you cannot afford deleting the row - You can use this logic;

First, insert (if not exists) and then update by filtering with the unique key.

Example

-- Table structure
CREATE TABLE players (
    id        INTEGER       PRIMARY KEY AUTOINCREMENT,
    user_name VARCHAR (255) NOT NULL
                            UNIQUE,
    age       INTEGER       NOT NULL
);

-- Insert if NOT exists
INSERT INTO players (user_name, age)
SELECT 'johnny', 20
WHERE NOT EXISTS (SELECT 1 FROM players WHERE user_name='johnny' AND age=20);

-- Update (will affect row, only if found)
-- no point to update user_name to 'johnny' since it's unique, and we filter by it as well
UPDATE players 
SET age=20 
WHERE user_name='johnny';

Regarding Triggers

Notice: I haven't tested it to see the which triggers are being called, but I assume the following:

if row does not exists

• BEFORE INSERT
• INSERT using INSTEAD OF
• AFTER INSERT
• BEFORE UPDATE
• UPDATE using INSTEAD OF
• AFTER UPDATE

if row does exists

• BEFORE UPDATE
• UPDATE using INSTEAD OF
• AFTER UPDATE

Option 2: Insert or replace - keep your own ID

in this way you can have a single SQL command

-- Table structure
CREATE TABLE players (
    id        INTEGER       PRIMARY KEY AUTOINCREMENT,
    user_name VARCHAR (255) NOT NULL
                            UNIQUE,
    age       INTEGER       NOT NULL
);

-- Single command to insert or update
INSERT OR REPLACE INTO players 
(id, user_name, age) 
VALUES ((SELECT id from players WHERE user_name='johnny' AND age=20),
        'johnny',
        20);

Edit: added option 2.

Find can be used to print out the file-size in bytes with %s as a printf. %h/%f prints the directory prefix and filename respectively. \n forces a newline.

Example

find . -size +10000k -printf "%h/%f,%s\n"

Output

./DOTT/extract/DOTT/TENTACLE.001,11358470
./DOTT/Day Of The Tentacle.nrg,297308316
./DOTT/foo.iso,297001116

Here is a generic working solution based on @Beta's

I'm using GNU Make 4.1 with SHELL=/bin/bash atop my Makefile, so YMMV!

This allows us to accept extra arguments (by doing nothing when we get a job that doesn't match, rather than throwing an error).

%:
    @:

And this is a macro which gets the args for us:

args = `arg="$(filter-out $@,$(MAKECMDGOALS))" && echo $${arg:-${1}}`

Here is a job which might call this one:

test:
    @echo $(call args,defaultstring)

The result would be:

$ make test
defaultstring
$ make test hi
hi

Note! You might be better off using a "Taskfile", which is a bash pattern that works similarly to make, only without the nuances of Maketools. See https://github.com/adriancooney/Taskfile

dic0.update(dic1)

Note this doesn't actually return the combined dictionary, it just mutates dic0.

CentOS is Linux, so as in just about all other Unix/Linux systems, you have the find command. To search for files within the current directory:

find -name "filename"

You can also have wildcards inside the quotes, and not just a strict filename. You can also explicitly specify a directory to start searching from as the first argument to find:

find / -name "filename"

will look for "filename" or all the files that match the regex expression in between the quotes, starting from the root directory. You can also use single quotes instead of double quotes, but in most cases you don't need either one, so the above commands will work without any quotes as well. Also, for example, if you're searching for java files and you know they are somewhere in your /home/username, do:

find /home/username -name *.java

There are many more options to the find command and you should do a:

man find

to learn more about it.

One more thing: if you start searching from / and are not root or are not sudo running the command, you might get warnings that you don't have permission to read certain directories. To ignore/remove those, do:

find / -name 'filename' 2>/dev/null

That just redirects the stderr to /dev/null.

java.exe is associated with the console, whereas javaw.exe doesn't have any such association. So, when java.exe is run, it automatically opens a command prompt window where output and error streams are shown.

Although it does not seem to be the case for your situation, sometimes a connection refused error can also indicate that there is an ip address conflict on your network. You can search for possible ip conflicts by running:

 arp-scan -I eth0 -l | grep <ipaddress>

and

arping <ipaddress>

This AskUbuntu question has some more information also.

The PID is stored in $$.

Example: kill -9 $$ will kill the shell instance it is called from.

There are a few ways to handle rendering/showing controls on the page and you should take note to what happens with each method.

Rendering and Visibility

There are some instances where elements on your page don't need to be rendered for the user because of some type of logic or database value. In this case, you can prevent rendering (creating the control on the returned web page) altogether. You would want to do this if the control doesn't need to be shown later on the client side because no matter what, the user viewing the page never needs to see it.

Any controls or elements can have their visibility set from the server side. If it is a plain old html element, you just need to set the runat attribute value to server on the markup page.

<div id="myDiv" runat="server"></div>

The decision to render the div or not can now be done in the code behind class like so:

myDiv.Visible = someConditionalBool;

If set to true, it will be rendered on the page and if it's false it won't be rendered at all, not even hidden.

Client Side Hiding

Hiding an element is done on the client side only. Meaning, it's rendered but it has a display CSS style set on it which instructs your browser to not show it to the user. This is beneficial when you want to hide/show things based on user input. It's important to know that the element CAN be hidden on the server side too as long as the element/control has runat=server set just as I explained in the previous example.

Hiding in the Code Behind Class

To hide an element that you want rendered to the page but hidden is another simple single line of code:

myDiv.Style["display"] = "none";

If you have a need to remove the display style server side, it can be done by removing the display style, or setting it to a different value like inline or block (values described here).

myDiv.Style.Remove("display");
// -- or --
myDiv.Style["display"] = "inline";

Hiding on the Client Side with javascript

Using plain old javascript, you can easily hide the same element in this manner

var myDivElem = document.getElementById("myDiv");
myDivElem.style.display = "none";

// then to show again
myDivElem.style.display = "";

jQuery makes hiding elements a little simpler if you prefer to use jQuery:

var myDiv = $("#<%=myDiv.ClientID%>");
myDiv.hide();

// ... and to show 
myDiv.show();

add Something like script.js?a=[random Number] with the Random number generated by PHP.

Have you tried expire=0, the pragma "no-cache" and "cache-control=NO-CACHE"? (I dunno what they say about Scripts).

Here is another approach, up to the OP to choose which one he prefers.

When including the code below in the __init__.py file before any other code, messages printed with print and any errors will no longer be logged to Ableton's Log.txt but to separate files on your disk:

import sys

path = "/Users/#username#"

errorLog = open(path + "/stderr.txt", "w", 1)
errorLog.write("---Starting Error Log---\n")
sys.stderr = errorLog
stdoutLog = open(path + "/stdout.txt", "w", 1)
stdoutLog.write("---Starting Standard Out Log---\n")
sys.stdout = stdoutLog

(for Mac, change #username# to the name of your user folder. On Windows the path to your user folder will have a different format)

When you open the files in a text editor that refreshes its content when the file on disk is changed (example for Mac: TextEdit does not but TextWrangler does), you will see the logs being updated in real-time.

If you want both to reference the same variable, one of them should have int k;, and the other should have extern int k;

For this situation, you typically put the definition (int k;) in one .cpp file, and put the declaration (extern int k;) in a header, to be included wherever you need access to that variable.

If you want each k to be a separate variable that just happen to have the same name, you can either mark them as static, like: static int k; (in all files, or at least all but one file). Alternatively, you can us an anonymous namespace:

namespace { 
   int k;
};

Again, in all but at most one of the files.

In C, the compiler generally isn't quite so picky about this. Specifically, C has a concept of a "tentative definition", so if you have something like int k; twice (in either the same or separate source files) each will be treated as a tentative definition, and there won't be a conflict between them. This can be a bit confusing, however, because you still can't have two definitions that both include initializers--a definition with an initializer is always a full definition, not a tentative definition. In other words, int k = 1; appearing twice would be an error, but int k; in one place and int k = 1; in another would not. In this case, the int k; would be treated as a tentative definition and the int k = 1; as a definition (and both refer to the same variable).

The non-greedy ? works perfectly fine. It's just that you need to select dot matches all option in the regex engines (regexpal, the engine you used, also has this option) you are testing with. This is because, regex engines generally don't match line breaks when you use .. You need to tell them explicitly that you want to match line-breaks too with .

For example,

<img\s.*?>

works fine!

Check the results here.

Also, read about how dot behaves in various regex flavours.

I should like to contribute the modern answer. This involves using java.time, the modern Java date and time API, and not the old Date nor Calendar except where there’s no way to avoid it.

Your issue is very likely really a timezone issue. When it is Tue Aug 09 00:00:00 IST 2011, in time zones west of IST midnight has not yet been reached. It is still Aug 8. If for example your API for putting the date into Excel expects UTC, the date will be the day before the one you intended. I believe the real and good solution is to produce a date-time of 00:00 UTC (or whatever time zone or offset is expected and used at the other end).

    LocalDate yourDate = LocalDate.of(2018, Month.FEBRUARY, 27);
    ZonedDateTime utcDateDime = yourDate.atStartOfDay(ZoneOffset.UTC);
    System.out.println(utcDateDime);

This prints

2018-02-27T00:00Z

Z means UTC (think of it as offset zero from UTC or Zulu time zone). Better still, of course, if you could pass the LocalDate from the first code line to Excel. It doesn’t include time-of-day, so there is no confusion possible. On the other hand, if you need an old-fashioned Date object for that, convert just before handing the Date on:

    Date oldfashionedDate = Date.from(utcDateDime.toInstant());
    System.out.println(oldfashionedDate);

On my computer this prints

Tue Feb 27 01:00:00 CET 2018

Don’t be fooled, it is correct. My time zone (Central European Time) is at offset +01:00 from UTC in February (standard time), so 01:00:00 here is equal to 00:00:00 UTC. It’s just Date.toString() grabbing the JVMs time zone and using it for producing the string.

How can I set it to something like 5:30 pm?

To answer your direct question directly, if you have a ZonedDateTime, OffsetDateTime or LocalDateTime, in all of these cases the following will accomplish what you asked for:

    yourDateTime = yourDateTime.with(LocalTime.of(17, 30));

If yourDateTime was a LocalDateTime of 2018-02-27T00:00, it will now be 2018-02-27T17:30. Similarly for the other types, only they include offset and time zone too as appropriate.

If you only had a date, as in the first snippet above, you can also add time-of-day information to it:

    LocalDate yourDate = LocalDate.of(2018, Month.FEBRUARY, 27);
    LocalDateTime dateTime = yourDate.atTime(LocalTime.of(17, 30));

For most purposes you should prefer to add the time-of-day in a specific time zone, though, for example

    ZonedDateTime dateTime = yourDate.atTime(LocalTime.of(17, 30))
            .atZone(ZoneId.of("Asia/Kolkata"));

This yields 2018-02-27T17:30+05:30[Asia/Kolkata].

Date and Calendar vs java.time

The Date class that you use as well as Calendar and SimpleDateFormat used in the other answers are long outdated, and SimpleDateFormat in particular has proven troublesome. In all cases the modern Java date and time API is so much nicer to work with. Which is why I wanted to provide this answer to an old question that is still being visited.

Link: Oracle Tutorial Date Time, explaining how to use java.time.

=> check there will be some instance of application installed partially.

=> first of all uninstall that instance from uninstall application.

=> then,clean,Rebuild,and try to deploy.

this solved my issue.hope it helps you too. Best Regards.

For your particular example, I would just do this, since you obviously don't care about actually having the browser get the redirect anyway (by virtue of accepting the answer you have already accepted):

[AcceptVerbs(HttpVerbs.Get)]
public ActionResult Index() {
   // obviously these values might come from somewhere non-trivial
   return Index(2, "text");
}

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Index(int someValue, string anotherValue) {
   // would probably do something non-trivial here with the param values
   return View();
}

That works easily and there is no funny business really going on - this allows you to maintain the fact that the second one really only accepts HTTP POST requests (except in this instance, which is under your control anyway) and you don't have to use TempData either, which is what the link you posted in your answer is suggesting.

I would love to know what is "wrong" with this, if there is anything. Obviously, if you want to really have sent to the browser a redirect, this isn't going to work, but then you should ask why you would be trying to convert that regardless, since it seems odd to me.

Hope that helps.

How to reproduce that error:

#include <iostream>
#include <stdlib.h>
#include <string>
#include <thread>
using namespace std;
void task1(std::string msg){
  cout << "task1 says: " << msg;
}
int main() { 
  std::thread t1(task1, "hello"); 
  return 0;
}

Compile and run:

el@defiant ~/foo4/39_threading $ g++ -o s s.cpp -pthread -std=c++11
el@defiant ~/foo4/39_threading $ ./s
terminate called without an active exception
Aborted (core dumped)

You get that error because you didn't join or detach your thread.

One way to fix it, join the thread like this:

#include <iostream>
#include <stdlib.h>
#include <string>
#include <thread>
using namespace std;
void task1(std::string msg){
  cout << "task1 says: " << msg;
}
int main() { 
  std::thread t1(task1, "hello"); 
  t1.join();
  return 0;
}

Then compile and run:

el@defiant ~/foo4/39_threading $ g++ -o s s.cpp -pthread -std=c++11
el@defiant ~/foo4/39_threading $ ./s
task1 says: hello

The other way to fix it, detach it like this:

#include <iostream>
#include <stdlib.h>
#include <string>
#include <unistd.h>
#include <thread>
using namespace std;
void task1(std::string msg){
  cout << "task1 says: " << msg;
}
int main() 
{ 
     {

        std::thread t1(task1, "hello"); 
        t1.detach();

     } //thread handle is destroyed here, as goes out of scope!

     usleep(1000000); //wait so that hello can be printed.
}

Compile and run:

el@defiant ~/foo4/39_threading $ g++ -o s s.cpp -pthread -std=c++11
el@defiant ~/foo4/39_threading $ ./s
task1 says: hello

Read up on detaching C++ threads and joining C++ threads.

Firstly, I would try a non-secure websocket connection. So remove one of the s's from the connection address:

conn = new WebSocket('ws://localhost:8080');

If that doesn't work, then the next thing I would check is your server's firewall settings. You need to open port 8080 both in TCP_IN and TCP_OUT.

The command is this:

mysqlcheck -u root -p --auto-repair --check --all-databases

You must supply the password when asked,

or you can run this one but it's not recommended because the password is written in clear text:

mysqlcheck -u root --password=THEPASSWORD --auto-repair --check --all-databases

Just as men and women are fundamentally different (according to John Gray, author of Men Are from Mars, Women Are from Venus), primitive variables and object reference variables differ from each other in multiple ways. The basic difference is that primitive variables store the actual values, whereas reference variables store the addresses of the objects they refer to. Let’s assume that a class Person is already defined. If you create an int variable a, and an object reference variable person, they will store their values in memory as shown in figure 2.13.

int a = 77;
Person person = new Person();

HTML tag is just opening or closing entity. For example:

<p> and </p> are called HTML tags

HTML element encompasses opening tag, closing tag, content (optional for content-less tags) Eg:

<p>This is the content</p> : This complete thing is called a HTML element

You are missing two closing parentheses...and I am not sure an ampersand works as a string concatenation operator. Try '+'

SELECT dbo.COL_V_Cost_GEMS_Detail.TNG_SYS_NR AS [EHP Code], 
dbo.COL_TBL_VCOURSE.TNG_NA AS [Course Title],

file Protocol
Opens a file on a local or network drive.

Syntax

Copy
 file:///sDrives[|sFile]
Tokens 

sDrives
Specifies the local or network drive.

sFile
Optional. Specifies the file to open. If sFile is omitted and the account accessing the drive has permission to browse the directory, a list of accessible files and directories is displayed.

Remarks

The file protocol and sDrives parameter can be omitted and substituted with just the command line representation of the drive letter and file location. For example, to browse the My Documents directory, the file protocol can be specified as file:///C|/My Documents/ or as C:\My Documents. In addition, a single '\' is equivalent to specifying the root directory on the primary local drive. On most computers, this is C:.

Available as of Microsoft Internet Explorer 3.0 or later.

Note Internet Explorer 6 Service Pack 1 (SP1) no longer allows browsing a local machine from the Internet zone. For instance, if an Internet site contains a link to a local file, Internet Explorer 6 SP1 displays a blank page when a user clicks on the link. Previous versions of Windows Internet Explorer followed the link to the local file.

Example

The following sample demonstrates four ways to use the File protocol.

Copy

//Specifying a drive and a file name. 

file:///C|/My Documents/ALetter.html

//Specifying only a drive and a path to browse the directory. 

file:///C|/My Documents/

//Specifying a drive and a directory using the command line representation of the directory location. 

C:\My Documents\

//Specifying only the directory on the local primary drive. 

\My Documents\

You can use a collection initializer:

UserCode = new byte[]{0x20,0x20,0x20,0x20,0x20,0x20};

This will work better than Repeat if the values are not identical.

git rm -r .
git checkout HEAD~3 .
git commit

After the commit, files in the new HEAD will be the same as they were in the revision HEAD~3.

I just had this problem also. Tried all the suggestions here, but they didn't help.

I found another thing to check that fixed it for me. In Visual Studio, right-click on the project and open "Properties". Click on the "Compile" (or "Build") tab and then click on "Advanced Compile Options" at the bottom.

Check the dropdown "Target CPU". It should match the "Platform" you are building. That is, if you are building "Any CPU" then "Target CPU" should say "Any CPU". Go through all of your Platforms by making them active and check this setting.

You can overwrite the colors in your css, for example for Danger button:

.btn-danger { border-color: #[insert color here]; background-color: #[insert color here];

.btn-danger:hover { border-color: #[insert color here]; background-color: #[insert color here]; }

Whatever you do to secure your secret keys is not going to be a real solution. If developer can decompile the application there is no way to secure the key, hiding the key is just security by obscurity and so is code obfuscation. Problem with securing a secret key is that in order to secure it you have to use another key and that key needs to also be secured. Think of a key hidden in a box that is locked with a key. You place a box inside a room and lock the room. You are left with another key to secure. And that key is still going to be hardcoded inside your application.

So unless the user enters a PIN or a phrase there is no way to hide the key. But to do that you would have to have a scheme for managing PINs happening out of band, which means through a different channel. Certainly not practical for securing keys for services like Google APIs.

You can use killall command as well .

-o, --older-than Match only processes that are older (started before) the time specified. The time is specified as a float then a unit. The units are s,m,h,d,w,M,y for seconds, minutes, hours, days,

-e, --exact Require an exact match for very long names.

-r, --regexp Interpret process name pattern as an extended regular expression.

This worked like a charm.

If you really need to do this, use reverse proxy.

For example, with nginx as reverse proxy

server {
  listen       api.mydomain.com:80;
  server_name  api.mydomain.com;
  location / {
    proxy_pass http://127.0.0.1:8000;
  }
}

If I understand what you're asking, this should do the trick:

// the more standards compliant browsers (mozilla/netscape/opera/IE7) use 
// window.innerWidth and window.innerHeight

var windowHeight;

if (typeof window.innerWidth != 'undefined')
{
    windowHeight = window.innerHeight;
}
// IE6 in standards compliant mode (i.e. with a valid doctype as the first 
// line in the document)
else if (typeof document.documentElement != 'undefined'
        && typeof document.documentElement.clientWidth != 'undefined' 
        && document.documentElement.clientWidth != 0)
{
    windowHeight = document.documentElement.clientHeight;
}
// older versions of IE
else
{
    windowHeight = document.getElementsByTagName('body')[0].clientHeight;
}

document.getElementById("yourDiv").height = windowHeight - 300 + "px";

In the current version of Sublime Text 2 (Build: 2139), you can set the syntax for all files of a certain file extension using an option in the menu bar. Open a file with the extension you want to set a default for and navigate through the following menus: View -> Syntax -> Open all with current extension as... ->[your syntax choice].

Updated 2012-06-28: Recent builds of Sublime Text 2 (at least since Build 2181) have allowed the syntax to be set by clicking the current syntax type in the lower right corner of the window. This will open the syntax selection menu with the option to Open all with current extension as... at the top of the menu.

Updated 2016-04-19: As of now, this also works for Sublime Text 3.

TensorBoard isn't a separate component. TensorBoard comes packaged with TensorFlow.

Be careful counting number of documents for large collections. It is a little bit complex with firestore database if you want to have a precalculated counter for every collection.

Code like this doesn't work in this case:

export const customerCounterListener = 
    functions.firestore.document('customers/{customerId}')
    .onWrite((change, context) => {

    // on create
    if (!change.before.exists && change.after.exists) {
        return firestore
                 .collection('metadatas')
                 .doc('customers')
                 .get()
                 .then(docSnap =>
                     docSnap.ref.set({
                         count: docSnap.data().count + 1
                     }))
    // on delete
    } else if (change.before.exists && !change.after.exists) {
        return firestore
                 .collection('metadatas')
                 .doc('customers')
                 .get()
                 .then(docSnap =>
                     docSnap.ref.set({
                         count: docSnap.data().count - 1
                     }))
    }

    return null;
});

The reason is because every cloud firestore trigger has to be idempotent, as firestore documentation say: https://firebase.google.com/docs/functions/firestore-events#limitations_and_guarantees

Solution

So, in order to prevent multiple executions of your code, you need to manage with events and transactions. This is my particular way to handle large collection counters:

const executeOnce = (change, context, task) => {
    const eventRef = firestore.collection('events').doc(context.eventId);

    return firestore.runTransaction(t =>
        t
         .get(eventRef)
         .then(docSnap => (docSnap.exists ? null : task(t)))
         .then(() => t.set(eventRef, { processed: true }))
    );
};

const documentCounter = collectionName => (change, context) =>
    executeOnce(change, context, t => {
        // on create
        if (!change.before.exists && change.after.exists) {
            return t
                    .get(firestore.collection('metadatas')
                    .doc(collectionName))
                    .then(docSnap =>
                        t.set(docSnap.ref, {
                            count: ((docSnap.data() && docSnap.data().count) || 0) + 1
                        }));
        // on delete
        } else if (change.before.exists && !change.after.exists) {
            return t
                     .get(firestore.collection('metadatas')
                     .doc(collectionName))
                     .then(docSnap =>
                        t.set(docSnap.ref, {
                            count: docSnap.data().count - 1
                        }));
        }

        return null;
    });

Use cases here:

/**
 * Count documents in articles collection.
 */
exports.articlesCounter = functions.firestore
    .document('articles/{id}')
    .onWrite(documentCounter('articles'));

/**
 * Count documents in customers collection.
 */
exports.customersCounter = functions.firestore
    .document('customers/{id}')
    .onWrite(documentCounter('customers'));

As you can see, the key to prevent multiple execution is the property called eventId in the context object. If the function has been handled many times for the same event, the event id will be the same in all cases. Unfortunately, you must have "events" collection in your database.

This will work also:

for i in {0..9}{0..9}{0..9}{0..9}
do
  echo "$i"
done

To add to the previous explanations, static method calls are bound to a specific method at compile-time, which rather rules out polymorphic behavior.

Whilst I'm sure POCO means Plain Old Class Object or Plain Old C Object to 99.9% of people here, POCO is also Animator Pro's (Autodesk) built in scripting language.

I'll have a go at this complicated subject.

What is origin?

The origin itself is the name of a host (scheme, hostname, and port) i.g. https://www.google.com or could be a locally opened file file:// etc.. It is where something (i.g. a web page) originated from. When you open your web browser and go to https://www.google.com, the origin of the web page that is displayed to you is https://www.google.com. You can see this in Chrome Dev Tools under Security:

The same applies for if you open a local HTML file via your file explorer (which is not served via a server):

What has this got to do with CORS issues?

When you open your browser and go to https://website.com, that website will have the origin of https://website.com. This website will most likely only fetch images, icons, js files and do API calls towards https://website.com, basically it is calling the same server as it was served from. It is doing calls to the same origin.

If you open your web browser and open a local HTML file and in that html file there is javascript which wants to do a request to google for example, you get the following error:

The same-origin policy tells the browser to block cross-origin requests. In this instance origin null is trying to do a request to https://www.google.com (a cross-origin request). The browser will not allow this because of the CORS Policy which is set and that policy is that cross-origin requests is not allowed.

Same applies for if my page was served from a server on localhost:

Localhost server example

If we host our own localhost API server running on localhost:3000 with the following code:

const express = require('express')
const app = express()
 
app.use(express.static('public'))

app.get('/hello', function (req, res) {
    // res.header("Access-Control-Allow-Origin", "*");
    res.send('Hello World');
})
 
app.listen(3000, () => {
    console.log('alive');
})

And open a HTML file (that does a request to the localhost:3000 server) directory from the file explorer the following error will happen:

Since the web page was not served from the localhost server on localhost:3000 and via the file explorer the origin is not the same as the server API origin, hence a cross-origin request is being attempted. The browser is stopping this attempt due to CORS Policy.

But if we uncomment the commented line:

const express = require('express')
const app = express()
 
app.use(express.static('public'))

app.get('/hello', function (req, res) {
    res.header("Access-Control-Allow-Origin", "*");
    res.send('Hello World');
})
 
app.listen(3000, () => {
    console.log('alive');
})

And now try again:

It works, because the server which sends the HTTP response included now a header stating that it is ok for cross-origin requests to happen to the server, this means the browser will let it happen, hence no error.

How to fix things

1. Serve the page from the same origin as where the requests you are making reside (same host).
2. Allow the server to receive cross-origin requests by explicitly stating it in the response headers.
3. Don't use a browser. Use cURL for example, it doesn't care about CORS Policies like browsers do and will get you what you want.

Example flow

Following is taken from: https://web.dev/cross-origin-resource-sharing/#how-does-cors-work

Remember, the same-origin policy tells the browser to block cross-origin requests. When you want to get a public resource from a different origin, the resource-providing server needs to tell the browser "This origin where the request is coming from can access my resource". The browser remembers that and allows cross-origin resource sharing.

• Step 1: client (browser) request When the browser is making a cross-origin request, the browser adds an Origin header with the current origin (scheme, host, and port).

• Step 2: server response On the server side, when a server sees this header, and wants to allow access, it needs to add an Access-Control-Allow-Origin header to the response specifying the requesting origin (or * to allow any origin.)

• Step 3: browser receives response When the browser sees this response with an appropriate Access-Control-Allow-Origin header, the browser allows the response data to be shared with the client site.

Here is another good answer, more detailed as to what is happening: https://stackoverflow.com/a/10636765/1137669

Ok, instead of identifying players by name track with sockets through which they have connected. You can have a implementation like

Server

var allClients = [];
io.sockets.on('connection', function(socket) {
   allClients.push(socket);

   socket.on('disconnect', function() {
      console.log('Got disconnect!');

      var i = allClients.indexOf(socket);
      allClients.splice(i, 1);
   });
});

Hope this will help you to think in another way

If you want to access referrer and user-agent, those are available to client-side Javascript, but not by accessing the headers directly.

To retrieve the referrer, use document.referrer.
To access the user-agent, use navigator.userAgent.

As others have indicated, the HTTP headers are not available, but you specifically asked about the referer and user-agent, which are available via Javascript.

This works and gives you the installed at path for each gem. This super helpful when trying to do multi-stage docker builds.. You can copy in the specific directory post-bundle install.

  State machine mixin for Ruby objects

In Rails 3.1, you should use the query interface:

• new(attributes)
• create(attributes)
• create!(attributes)
• find(id_or_array)
• destroy(id_or_array)
• destroy_all
• delete(id_or_array)
• delete_all
• update(ids, updates)
• update_all(updates)
• exists?

update and update_all are the operation you need.

Good question with a simple answer: you can't!

Javascript is a client-side programming language, therefore it works on the client's machine, so you can't actually hide anything from the client.
Obfuscating your code is a good solution, but it's not enough, because, although it is hard, someone could decipher your code and "steal" your script.
There are a few ways of making your code hard to be stolen, but as i said nothing is bullet-proof.

Off the top of my head, one idea is to restrict access to your external js files from outside the page you embed your code in. In that case, if you have

<script type="text/javascript" src="myJs.js"></script>

and someone tries to access the myJs.js file in browser, he shouldn't be granted any access to the script source.
For example, if your page is written in php, you can include the script via the include function and let the script decide if it's safe" to return it's source.
In this example, you'll need the external "js" (written in php) file myJs.php :

<?php
    $URL = $_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];
    if ($URL != "my-domain.com/my-page.php")
    die("/\*sry, no acces rights\*/");
?>
// your obfuscated script goes here

that would be included in your main page my-page.php :

<script type="text/javascript">
    <?php include "myJs.php"; ?>;
</script> 

This way, only the browser could see the js file contents.

Another interesting idea is that at the end of your script, you delete the contents of your dom script element, so that after the browser evaluates your code, the code disappears :

<script id="erasable" type="text/javascript">
    //your code goes here
    document.getElementById('erasable').innerHTML = "";
</script>

These are all just simple hacks that cannot, and I can't stress this enough : cannot, fully protect your js code, but they can sure piss off someone who is trying to "steal" your code.

Update:

I recently came across a very interesting article written by Patrick Weid on how to hide your js code, and he reveals a different approach: you can encode your source code into an image! Sure, that's not bullet proof either, but it's another fence that you could build around your code.
The idea behind this approach is that most browsers can use the canvas element to do pixel manipulation on images. And since the canvas pixel is represented by 4 values (rgba), each pixel can have a value in the range of 0-255. That means that you can store a character (actual it's ascii code) in every pixel. The rest of the encoding/decoding is trivial.
Thanks, Patrick!

I had the same problem and I'm using Ubuntu 15.10.

In my case, to solve this issue, I installed the package php7.0-xml using the Synaptic package manager, which include SimpleXml. So, after restart my Apache server, my problem was solved. This package came in the Debian version and you can find it here: https://packages.debian.org/sid/php7.0-xml.

That said, everybody seems to come to this page for the more general answer to your question:

Selecting a random row in SQL

Select a random row with MySQL:

SELECT column FROM table
ORDER BY RAND()
LIMIT 1

Select a random row with PostgreSQL:

SELECT column FROM table
ORDER BY RANDOM()
LIMIT 1

Select a random row with Microsoft SQL Server:

SELECT TOP 1 column FROM table
ORDER BY NEWID()

Select a random row with IBM DB2

SELECT column, RAND() as IDX 
FROM table 
ORDER BY IDX FETCH FIRST 1 ROWS ONLY

Select a random record with Oracle:

SELECT column FROM
( SELECT column FROM table
ORDER BY dbms_random.value )
WHERE rownum = 1

Select a random row with sqlite:

SELECT column FROM table 
ORDER BY RANDOM() LIMIT 1

The settings file is never created automatically, you must create it yourself, whether you use embedded or "real" maven.

Create it at the following location <your home folder>/.m2/settings.xml e.g. C:\Users\YourUserName\.m2\settings.xml on Windows or /home/YourUserName/.m2/settings.xml on Linux

Here's an empty skeleton you can use:

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      http://maven.apache.org/xsd/settings-1.0.0.xsd">
  <localRepository/>
  <interactiveMode/>
  <usePluginRegistry/>
  <offline/>
  <pluginGroups/>
  <servers/>
  <mirrors/>
  <proxies/>
  <profiles/>
  <activeProfiles/>
</settings>

If you use Eclipse to edit it, it will give you auto-completion when editing it.

And here's the Maven settings.xml Reference page

window.onbeforeunload = function () {
    return "Do you really want to close?";
};

Less than or equal:

User.objects.filter(userprofile__level__lte=0)

Greater than or equal:

User.objects.filter(userprofile__level__gte=0)

Likewise, lt for less than and gt for greater than. You can find them all in the documentation.

I got similar issue. The mistake i made was I did not add service in the providers array in app.module.ts. Hope this helps, Thank You.

You can assign an iterable to side_effect, and the mock will return the next value in the sequence each time it is called:

>>> from unittest.mock import Mock
>>> m = Mock()
>>> m.side_effect = ['foo', 'bar', 'baz']
>>> m()
'foo'
>>> m()
'bar'
>>> m()
'baz'

Quoting the Mock() documentation:

If side_effect is an iterable then each call to the mock will return the next value from the iterable.

You post JSON like this

$.ajax(url, {
    data : JSON.stringify(myJSObject),
    contentType : 'application/json',
    type : 'POST',
    ...

if you pass an object as settings.data jQuery will convert it to query parameters and by default send with the data type application/x-www-form-urlencoded; charset=UTF-8, probably not what you want

While moopasta's answer works, it doesn't appear to allow wildcards and there is another (potentially better) option. The Chromium project has some HTTP authentication documentation that is useful but incomplete.

Specifically the option that I found best is to whitelist sites that you would like to allow Chrome to pass authentication information to, you can do this by:

• Launching Chrome with the auth-server-whitelist command line switch. e.g. --auth-server-whitelist="*example.com,*foobar.com,*baz". Downfall to this approach is that opening links from other programs will launch Chrome without the command line switch.
• Installing, enabling, and configuring the AuthServerWhitelist/"Authentication server whitelist" Group Policy or Local Group Policy. This seems like the most stable option but takes more work to setup. You can set this up locally, no need to have this remotely deployed.

Those looking to set this up for an enterprise can likely follow the directions for using Group Policy or the Admin console to configure the AuthServerWhitelist policy. Those looking to set this up for one machine only can also follow the Group Policy instructions:

1. Download and unzip the latest Chrome policy templates
2. Start > Run > gpedit.msc
3. Navigate to Local Computer Policy > Computer Configuration > Administrative Templates
4. Right-click Administrative Templates, and select Add/Remove Templates
5. Add the windows\adm\en-US\chrome.adm template via the dialog
6. In Computer Configuration > Administrative Templates > Classic Administrative Templates > Google > Google Chrome > Policies for HTTP Authentication enable and configure Authentication server whitelist
7. Restart Chrome and navigate to chrome://policy to view active policies

After you exit from one text field, you call [otherTextField becomeFirstResponder] and the next field gets focus.

This can actually be a tricky problem to deal with since often you'll also want to scroll the screen or otherwise adjust the position of the text field so it's easy to see when editing. Just make sure to do a lot of testing with coming into and out of the text fields in different ways and also leaving early (always give the user an option to dismiss the keyboard instead of going to the next field, usually with "Done" in the nav bar)

You can use Simple JSON for PHP. It sends the headers help you to forge the JSON.

It looks like :

<?php
// Include the json class
include('includes/json.php');

// Then create the PHP-Json Object to suits your needs

// Set a variable ; var name = {}
$Json = new json('var', 'name'); 
// Fire a callback ; callback({});
$Json = new json('callback', 'name'); 
// Just send a raw JSON ; {}
$Json = new json();

// Build data
$object = new stdClass();
$object->test = 'OK';
$arraytest = array('1','2','3');
$jsonOnly = '{"Hello" : "darling"}';

// Add some content
$Json->add('width', '565px');
$Json->add('You are logged IN');
$Json->add('An_Object', $object);
$Json->add("An_Array",$arraytest);
$Json->add("A_Json",$jsonOnly);

// Finally, send the JSON.

$Json->send();
?>

If you need the path and thedomain for each cookie, which get_dict() is not exposes, you can parse the cookies manually, for instance:

[
    {'name': c.name, 'value': c.value, 'domain': c.domain, 'path': c.path}
    for c in session.cookies
]

You can easily use .replace() as also previously described. But it is also important to keep in mind that strings are immutable. Hence if you do not assign the change you are making to a variable, then you will not see any change. Let me explain by;

    >>stuff = "bin and small"
    >>stuff.replace('and', ',')
    >>print(stuff)
    "big and small" #no change

To observe the change you want to apply, you can assign same or another variable;

    >>stuff = "big and small"
    >>stuff = stuff.replace("and", ",")   
    >>print(stuff)
    'big, small'

I had the same problem truying to connect from linux server to EC2, you have two make sure about to things that "ALL ICMP" is added from EC2 as shown above and that alone won't work, you have to update Ansible to newest version 2.4, it did not work with my previous version 2.2.

The following should do the trick:

div[class^='myclass'], div[class*=' myclass']{

This answer applies to this question if

1. You don't want to change your code
2. You don't want to change PYTHONPATH permanently

Temporarily modify PYTHONPATH

path below can be relative

PYTHONPATH=/path/to/dir python script.py

By setting the schedule period to 15 13 * * * you tell Jenkins to schedule the build every day of every month of every year at the 15th minute of the 13th hour of the day.

Jenkins used a cron expression, and the different fields are:

1. MINUTES Minutes in one hour (0-59)
2. HOURS Hours in one day (0-23)
3. DAYMONTH Day in a month (1-31)
4. MONTH Month in a year (1-12)
5. DAYWEEK Day of the week (0-7) where 0 and 7 are sunday

If you want to schedule your build every 5 minutes, this will do the job : */5 * * * *

If you want to schedule your build every day at 8h00, this will do the job : 0 8 * * *

For the past few versions (2014), Jenkins have a new parameter, H (extract from the Jenkins code documentation):

To allow periodically scheduled tasks to produce even load on the system, the symbol H (for “hash”) should be used wherever possible.

For example, using 0 0 * * * for a dozen daily jobs will cause a large spike at midnight. In contrast, using H H * * * would still execute each job once a day, but not all at the same time, better using limited resources.

Note also that:

The H symbol can be thought of as a random value over a range, but it actually is a hash of the job name, not a random function, so that the value remains stable for any given project.

More example of using 'H'

This should work. I would trim the whitespace from the input field first of all:

if($('#Field').val() != "") {
    var value = $('#Field').val().replace(/^\s\s*/, '').replace(/\s\s*$/, '');
    var intRegex = /^\d+$/;
    if(!intRegex.test(value)) {
        errors += "Field must be numeric.<br/>";
        success = false;
    }
} else {
    errors += "Field is blank.</br />";
    success = false;
}

I guess what you're trying to do, is to keep the header fixed and to scroll the body content. You can scroll the content into 2 directions:

• horizontally: you won't be able to scroll the content horizontally unless you use a slider (a jQuery slider for example). I would recommend to avoid using a table in this case.
• vertically: you won't be able to achieve that with a tbody tag, because assigning display:block or display:inline-block will break the layout of the table.

Explanation:

You have a sliding wrapper which will contain all the data.

Note the following:

.wrap_header{width:204px;}
.sliding_wrapper,
.wrap_body {width:221px;}

There's a difference of 17px because we need to take into consideration the width of the scrollbar.

a = " ".join(str(i) for i in range(10, 0, -1))
print (a)

Your code is absolutely fine. It just needs "exit 0" for a cleaner exit.

 tncserver.exe C:\Work -p4 -b57600 -r -cFE -tTNC426B
 exit 0

I have tried this and quite Simple process:

Created a new Package with required name--> Moved all my classes to this new package (Right click on previous package --> Refractor--> Move)

You have to allocate more space to the PermGenSpace of the tomcat JVM.

This can be done with the JVM argument : -XX:MaxPermSize=128m

By default, the PermGen space is 64M (and it contains all compiled classes, so if you have a lot of jar (classes) in your classpath, you may indeed fill this space).

On a side note, you can monitor the size of the PermGen space with JVisualVM and you can even inspect its content with YourKit Java Profiler

As an alternate you can use reactive forms. Here is an example: https://stackblitz.com/edit/angular-pqb2xx

Template

<form [formGroup]="mainForm" ng-submit="submitForm()">
  Global Price: <input type="number" formControlName="globalPrice">
  <button type="button" [disabled]="mainForm.get('globalPrice').value === null" (click)="applyPriceToAll()">Apply to all</button>
  <table border formArrayName="orderLines">
  <ng-container *ngFor="let orderLine of orderLines let i=index" [formGroupName]="i">
    <tr>
       <td>{{orderLine.time | date}}</td>
       <td>{{orderLine.quantity}}</td>
       <td><input formControlName="price" type="number"></td>
    </tr>
</ng-container>
  </table>
</form>

    ]
  constructor() {
    this.mainForm = this.getForm();
  }

  getForm(): FormGroup {
    return new FormGroup({

      orderLines: new FormArray(this.orderLines.map(this.getFormGroupForLine))
    })
  }

  }

  applyPriceToAll() {
    const formLines = this.mainForm.get('orderLines') as FormArray;
    const globalPrice = this.mainForm.get('globalPrice').value;
    formLines.controls.forEach(control => control.get('price').setValue(globalPrice));
    // optionally recheck value and validity without emit event.
  }

sometimes whenever you copy cURL, it contains --compressed. Remove it while import->Paste Raw Text-->click on import. It will also solve the problem if you are getting the syntax error in postman while importing any cURL.

Generally, when people copy cURL from any proxy tools like Charles, it happens.

From my experience, the most efficient way to flatten a list of lists is:

flat_list = []
map(flat_list.extend, list_of_list)

Some timeit comparisons with the other proposed methods:

list_of_list = [range(10)]*1000
%timeit flat_list=[]; map(flat_list.extend, list_of_list)
#10000 loops, best of 3: 119 µs per loop
%timeit flat_list=list(itertools.chain.from_iterable(list_of_list))
#1000 loops, best of 3: 210 µs per loop
%timeit flat_list=[i for sublist in list_of_list for i in sublist]
#1000 loops, best of 3: 525 µs per loop
%timeit flat_list=reduce(list.__add__,list_of_list)
#100 loops, best of 3: 18.1 ms per loop

Now, the efficiency gain appears better when processing longer sublists:

list_of_list = [range(1000)]*10
%timeit flat_list=[]; map(flat_list.extend, list_of_list)
#10000 loops, best of 3: 60.7 µs per loop
%timeit flat_list=list(itertools.chain.from_iterable(list_of_list))
#10000 loops, best of 3: 176 µs per loop

And this methods also works with any iterative object:

class SquaredRange(object):
    def __init__(self, n): 
        self.range = range(n)

FUNCTIONAL REQUIREMENTS the activities the system must perform

• business uses functions the users carry out
• use cases example if you are developing a payroll system required functions
• generate electronic fund transfers
• calculation commission amounts
• calculate payroll taxes
• report tax deduction to the IRS

One way to resolve this is to login to your root user in phpmyadmin, go to the users tab, find and select the specific user that can't access the select and other queries . Then tick the all checkboxes and just click go. Now that user can select, update and whatever they want.

HTML 5 invites you give add a lot of semantic value to your code. What's more, there are natives solution to embed multimedia content.

The rest is important, but it's more technical sugar that will save you from doing the same stuff with a client programming language.

you can use the google chart api and generate any color with rgb code on the fly:

example: marker with #ddd color:

http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|ddd

include as stated above with

 var marker = new google.maps.Marker({
    position: marker,
    title: 'Hello World',
    icon: 'http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|ddd'
});

You could use https://github.com/jankroken/commandline , here's how to do that:

To make this example work, I must make assumptions about what the arguments means - just picking something here...

-r opt1 => replyAddress=opt1
-S opt2 arg1 arg2 arg3 arg4 => subjects=[opt2,arg1,arg2,arg3,arg4]
--test = test=true (default false)
-A opt3 => address=opt3

this can then be set up this way:

public class MyProgramOptions {
  private String replyAddress;
  private String address;
  private List<String> subjects;
  private boolean test = false;

  @ShortSwitch("r")
  @LongSwitch("replyAddress") // if you also want a long variant. This can be skipped
  @SingleArgument
  public void setReplyAddress(String replyAddress) {
    this.replyAddress = replyAddress;
  }

  @ShortSwitch("S")
  @AllAvailableArguments
  public void setSubjects(List<String> subjects) {
    this.subjects = subjects;
  }

  @LongSwitch("test")
  @Toggle(true)
  public void setTest(boolean test) {
    this.test = test;
  }

  @ShortSwitch("A")
  @SingleArgument
  public void setAddress(String address) {
    this.address = address;
  }

  // getters...
}

and then in the main method, you can just do:

public final static void main(String[] args) {
  try {
    MyProgramOptions options = CommandLineParser.parse(MyProgramOptions.class, args, OptionStyle.SIMPLE);

    // and then you can pass options to your application logic...

  } catch
    ...
  }
}

MacVim is just Vim. Anything you are used to do in Vim will work exactly the same way in MacVim.

MacVim is more integrated in the whole OS than Vim in the Terminal or even GVim in Linux, it follows a lot of Mac OS X's conventions.

If you work mainly with GUI apps (YummyFTP + GitX + Charles, for example) you may prefer MacVim.

If you work mainly with CLI apps (ssh + svn + tcpdump, for example) you may prefer vim in the terminal.

Entering and leaving one realm (CLI) for the other (GUI) and vice-versa can be "expensive".

I use both MacVim and Vim depending on the task and the context: if I'm in CLI-land I'll just type vim filename and if I'm in GUI-land I'll just invoke Quicksilver and launch MacVim.

When I switched from TextMate I kind of liked the fact that MacVim supported almost all of the regular shortcuts Mac users are accustomed to. I added some of my own, mimiking TextMate but, since I was working in multiple environments I forced my self to learn the vim way. Now I use both MacVim and Vim almost exactly the same way. Using one or the other is just a question of context for me.

Also, like El Isra said, the default vim (CLI) in OS X is slightly outdated. You may install an up-to-date version via MacPorts or you can install MacVim and add an alias to your .profile:

alias vim='/path/to/MacVim.app/Contents/MacOS/Vim'

to have the same vim in MacVim and Terminal.app.

Another difference is that many great colorschemes out there work out of the box in MacVim but look terrible in the Terminal.app which only supports 8 colors (+ highlights) but you can use iTerm — which can be set up to support 256 colors — instead of Terminal.

So… basically my advice is to just use both.

EDIT: I didn't try it but the latest version of Terminal.app (in 10.7) is supposed to support 256 colors. I'm still on 10.6.x at work so I'll still use iTerm2 for a while.

EDIT: An even better way to use MacVim's CLI executable in your shell is to move the mvim script bundled with MacVim somewhere in your $PATH and use this command:

$ mvim -v

EDIT: Yes, Terminal.app now supports 256 colors. So if you don't need iTerm2's advanced features you can safely use the default terminal emulator.

FLCL's idea is very correct, I show you in a code:

    public class O1<T> where T: class
    {
        public Guid Id { get; }
        public O1(Guid id)
        {
            Id = id;
        }
        public bool IsNull => !GlobalHolder.Holder.ContainsKey(Id);
        public T Val => GlobalHolder.Holder.ContainsKey(Id) ? (T)GlobalHolder.Holder[Id] : null;
    }
    public class GlobalHolder
    {
        public static readonly Dictionary<Guid, object> Holder = new Dictionary<Guid, object>();
        public static O1<T> Instantiate<T>() where T: class, new()
        {
            var a = new T();
            var nguid = Guid.NewGuid();
            var b = new O1<T>(nguid);
            Holder[nguid] = a;
            return b;
        }
        public static void Destroy<T>(O1<T> obj) where T: class
        {
            Holder.Remove(obj.Id);
        }
    }

    public class Animal
    {

    }

    public class AnimalTest
    {
        public static void Test()
        {
            var tom = GlobalHolder.Instantiate<Animal>();
            var duplicateTomReference = tom;
            GlobalHolder.Destroy(tom);
            Console.WriteLine($"{duplicateTomReference.IsNull}");
            // prints true
        }
    }

Note: In this code sample, my naming convention comes from Unity.

This is the pattern I usually follow when setting up a harness for testing an abstract class:

public abstract class MyBase{
  /*...*/
  public abstract void VoidMethod(object param1);
  public abstract object MethodWithReturn(object param1);
  /*,,,*/
}

And the version I use under test:

public class MyBaseHarness : MyBase{
  /*...*/
  public Action<object> VoidMethodFunction;
  public override void VoidMethod(object param1){
    VoidMethodFunction(param1);
  }
  public Func<object, object> MethodWithReturnFunction;
  public override object MethodWithReturn(object param1){
    return MethodWihtReturnFunction(param1);
  }
  /*,,,*/
}

If the abstract methods are called when I don't expect it, the tests fail. When arranging the tests, I can easily stub out the abstract methods with lambdas that perform asserts, throw exceptions, return different values, etc.

The whole reason for having kubernetes is so it manages the containers for you so you don't have to care so much about the lifecyle of the containers in the pod.

Since you have a deployment setup that uses replica set. You can delete the pod using kubectl delete pod test-1495806908-xn5jn and kubernetes will manage the creation of a new pod with the 2 containers without any downtime. Trying to manually restart single containers in pods negates the whole benefits of kubernetes.

Please try this one works for me:

<ImageView android:id="@+id/image_view"     
  android:layout_width="wrap_content"  
  android:layout_height="wrap_content"  
  android:adjustViewBounds="true"  
  android:maxWidth="60dp" 
  android:layout_gravity="center" 
  android:maxHeight="60dp"  
  android:scaleType="fitCenter"  
  android:src="@drawable/icon"  
  /> 

On my machine (Windows7, 64bit) I could fix this by setting my execution environment to a 32bit variant of the jdk (I used 1.6.0_23). And I tried a lot of things before...

If you have already made some commits, you can do the following

git pull --rebase

This will place all your local commits on top of newly pulled changes.

BE VERY CAREFUL WITH THIS: this will probably overwrite all your present files with the files as they are at the head of the branch in the remote repo! If this happens and you didn't want it to you can UNDO THIS CHANGE with

git rebase --abort 

... naturally you have to do that before doing any new commits!

Put your JTable inside a JScrollPane. Try this:

add(new JScrollPane(scrTbl));

Also, it is very likely, that problem with proxy settings.

Any who didn't overcome Tomact starting problrem, - try in NetBeans choose No Proxy in the Tools -> Options -> General tab.

It helped me.

Except load the data cache asynchronously, you may require the UI cache, like setViewCacheSize

Except the the loading visible item data, you may require to load the approximity-visible item data

AndroidX Paging Library is another option, for example, you can load and cache and display 10,000,000 items to a RecyclerView from a SQLite database. refer to PagedList

Example: Suppose the listview visible item is [6,7,8,9,10], you may require to load [6,7,8,9,10] AND pre-load the item [1, 2, 3, 4, 5] & [11, 12, 13, 14, 15], because user probably scroll to the pre-page or post-page

You can also format the string like so:

>>> print ("{index}. {word} appears {count} times".format(index=1, word='Hello', count=42))

Which outputs

1. Hello appears 42 times.

Because the values are named, their order does not matter. Making the example below output the same as the above example.

>>> print ("{index}. {word} appears {count} times".format(count=42, index=1, word='Hello'))

Formatting string this way allows you to do this.

>>> data = {'count':42, 'index':1, 'word':'Hello'}
>>> print ("{index}. {word} appears {count} times.".format(**data))
1. Hello appears 42 times.

Use chown to change ownership and chmod to change rights.

use the -R option to apply the rights for all files inside of a directory too.

Note that both these commands just work for directories too. The -R option makes them also change the permissions for all files and directories inside of the directory.

For example

sudo chown -R username:group directory

will change ownership (both user and group) of all files and directories inside of directory and directory itself.

sudo chown username:group directory

will only change the permission of the folder directory but will leave the files and folders inside the directory alone.

you need to use sudo to change the ownership from root to yourself.

Edit:

Note that if you use chown user: file (Note the left-out group), it will use the default group for that user.

Also You can change the group ownership of a file or directory with the command:

chgrp group_name file/directory_name

You must be a member of the group to which you are changing ownership to.

You can find group of file as follows

# ls -l file
-rw-r--r-- 1 root family 0 2012-05-22 20:03 file

# chown sujit:friends file

User 500 is just a normal user. Typically user 500 was the first user on the system, recent changes (to /etc/login.defs) has altered the minimum user id to 1000 in many distributions, so typically 1000 is now the first (non root) user.

What you may be seeing is a system which has been upgraded from the old state to the new state and still has some processes knocking about on uid 500. You can likely change it by first checking if your distro should indeed now use 1000, and if so alter the login.defs file yourself, the renumber the user account in /etc/passwd and chown/chgrp all their files, usually in /home/, then reboot.

But in answer to your question, no, you should not really be worried about this in all likelihood. It'll be showing as "500" instead of a username because o user in /etc/passwd has a uid set of 500, that's all.

Also you can show your current numbers using id i'm willing to bet it comes back as 1000 for you.

I think somebody chose very unfortunate name for STATELESS concept and that's why the whole misunderstanding is caused. It's not about storing any kind of resources, but rather about the relationship between the client and the server.

Client: I'm keeping all the resources on my side and send you the "list" of all the important items which need to processed. Do your job.

Server: All right.. let me take the responsibility on filtering what's important to give you the proper response.

Which means that the server is the "slave" of the client and has to forget about his "master" after each request. Actually, STATELESS refers only to the state of the server.

You need to remove TFS credentials from Windows Vault to clear and force to ask new TFS credentials in Visual Studio

1. Go to Control Panel (Start -> Control Panel).

2. Click User Accounts ( or User Accounts and Family Safety->User Accounts in Windows 7 Machine)

3. Click Credential Manager (or Manage your credentials)

4. In Credential Manager page, you can see the two type of credentials

      i. Windows Credentials
      ii. Generic Credentials
   

5.Click on two credentials modify link, click the link Remove from vault to remove stored TFS credentials.

Now, When you login into Visual Studio you will be asked to give credentials to connect TFS.

Note: Don't forgot to uncheck the option Remember my credentials to force to ask credentials for every TFS connections.

SOLUTION OF Regsvr32: DllRegisterServer entry point was not found,

1. Go to systemdrive(generally c:)\system32 and search file "Regsvr32.exe"
2. Right click and click in properties and go to security tab and click in advanced button.
3. Click in owner tab and click edit and select administrators and click ok.
4. Click in permissions
5. Click in change permissions.
6. Choose administrators and click edit and put tick on full control and click ok.
7. Similarly, choose SYSTEM and edit and put tick on full control and click ok and click in other dialog box which are opened.
8. Now .dll files can be registered and error don't come, you should re-install any software whose dll files was not registered during installation.

I ran into the same issue, this was an exercise as part of a tutorial on lynda.com if I'm not wrong. The mistake I made was not selecting the runtime as Python 3.6 which is an option in the lamda function console.

In C/C++ you have header files (*.H). There you declare your functions/classes. So for example you will have to #include "second.h" to your main.cpp file.

In second.h you just declare like this void yourFunction(); In second.cpp you implement it like

void yourFunction() { 
   doSomethng(); 
}

Don't forget to #include "second.h" also in the beginning of second.cpp

Hope this helps:)

Use reduce, Luke!

function renderOptions(options) {
    return options.reduce(function (res, option) {
        if (!option.assigned) {
            res.push(someNewObject);
        }
        return res;
    }, []);   
}

Assuming the ID is unique:

var result = xmldoc.Element("Customers")
                   .Elements("Customer")
                   .Single(x => (int?)x.Attribute("ID") == 2);

You could also use First, FirstOrDefault, SingleOrDefault or Where, instead of Single for different circumstances.

Here is yet another approach, which was more convenient in my case (I just wanted to drop root privileges and do the rest of my script from restricted user): you can make the script restart itself from correct user. Let's suppose it is run as root initially. Then it will look like this:

#!/bin/bash
if [ $UID -eq 0 ]; then
  user=$1
  dir=$2
  shift 2     # if you need some other parameters
  cd "$dir"
  exec su "$user" "$0" -- "$@"
  # nothing will be executed beyond that line,
  # because exec replaces running process with the new one
fi

echo "This will be run from user $UID"
...

Unix

The commands env, set, and printenv display all environment variables and their values. env and set are also used to set environment variables and are often incorporated directly into the shell. printenv can also be used to print a single variable by giving that variable name as the sole argument to the command.

In Unix, the following commands can also be used, but are often dependent on a certain shell.

export VARIABLE=value  # for Bourne, bash, and related shells
setenv VARIABLE value  # for csh and related shells

Here is what the JSF javadocs have to say about the commandButton action attribute:

MethodExpression representing the application action to invoke when this component is activated by the user. The expression must evaluate to a public method that takes no parameters, and returns an Object (the toString() of which is called to derive the logical outcome) which is passed to the NavigationHandler for this application.

It would be illuminating to me if anyone can explain what that has to do with any of the answers on this page. It seems pretty clear that action refers to some page's filename and not a method.

var intArray = [1, 2, 3, 4, 5];
//lets use each function
$.each(intArray, function(index, element) {
  if (element === 3) {
    return false;
  }
  console.log(element); // prints only 1,2. Breaks the loop as soon as it encountered number 3
});

//lets use map function
$.map(intArray, function(element, index) {
  if (element === 3) {
    return false;
  }
  console.log(element); // prints only 1,2,4,5. skip the number 3.
});

Simple function for splitting a vector by simply using indexes - no need to over complicate this

vsplit <- function(v, n) {
    l = length(v)
    r = l/n
    return(lapply(1:n, function(i) {
        s = max(1, round(r*(i-1))+1)
        e = min(l, round(r*i))
        return(v[s:e])
    }))
}

chmod a+x modifies the argument's mode while chmod 755 sets it. Try both variants on something that has full or no permissions and you will notice the difference.

This question is really old, but I came across this page when I was looking for the easiest and quickest way to do this. Using Webpack is much simpler:

install webpack-dev-server

npm i -g webpack-dev-server

start webpack-dev-server with https

webpack-dev-server --https

In java as per my knowledge if you learner then, when you write int a; then in java generic it will compile code like Integer a = new Integer(). So,as per generics Integer is not used but int is used. so there is so such difference there.

I made some fixes for @Pinhassi solution. It handles some cases:

1.you can move cursor anywhere

2.minus sign handling

3.digitsbefore = 2 and digitsafter = 4 and you enter 12.4545. Then if you want to remove ".", it will not allow.

public class DecimalDigitsInputFilter implements InputFilter {
    private int mDigitsBeforeZero;
    private int mDigitsAfterZero;
    private Pattern mPattern;

    private static final int DIGITS_BEFORE_ZERO_DEFAULT = 100;
    private static final int DIGITS_AFTER_ZERO_DEFAULT = 100;

    public DecimalDigitsInputFilter(Integer digitsBeforeZero, Integer digitsAfterZero) {
    this.mDigitsBeforeZero = (digitsBeforeZero != null ? digitsBeforeZero : DIGITS_BEFORE_ZERO_DEFAULT);
    this.mDigitsAfterZero = (digitsAfterZero != null ? digitsAfterZero : DIGITS_AFTER_ZERO_DEFAULT);
    mPattern = Pattern.compile("-?[0-9]{0," + (mDigitsBeforeZero) + "}+((\\.[0-9]{0," + (mDigitsAfterZero)
        + "})?)||(\\.)?");
    }

Haha, I have been stuck at that point a while ago as well, so I am glad I can help you out with a solution, that worked for me at least :)

What you want to do is define a new style within values/styles.xml so it looks like this

<resources>
    <style name = "AppTheme" parent = "android:Theme.Holo.Light.DarkActionBar">
        <!-- Customize your theme here. -->
    </style>

    <style name = "NoActionBar" parent = "@android:style/Theme.Holo.Light">
        <item name = "android:windowActionBar">false</item>
        <item name = "android:windowNoTitle">true</item>
    </style>

</resources>

Only the NoActionBar style is intresting for you. At last you have to set is as your application's theme in the AndroidManifest.xml so it looks like this

<application
    android:allowBackup = "true"
    android:icon = "@drawable/ic_launcher"
    android:label = "@string/app_name"
    android:theme = "@style/NoActionBar"   <!--This is the important line-->
    >
    <activity
    [...]

I hope this helps, if not, let me know.

Sharing my notes which I usually maintain while reading from Internet, I hope it may be helpful to someone

Candidate Key or available keys

Candidate keys are those keys which is candidate for primary key of a table. In simple words we can understand that such type of keys which full fill all the requirements of primary key which is not null and have unique records is a candidate for primary key. So thus type of key is known as candidate key. Every table must have at least one candidate key but at the same time can have several.

Primary Key

Such type of candidate key which is chosen as a primary key for table is known as primary key. Primary keys are used to identify tables. There is only one primary key per table. In SQL Server when we create primary key to any table then a clustered index is automatically created to that column.

Foreign Key

Foreign key are those keys which is used to define relationship between two tables. When we want to implement relationship between two tables then we use concept of foreign key. It is also known as referential integrity. We can create more than one foreign key per table. Foreign key is generally a primary key from one table that appears as a field in another where the first table has a relationship to the second. In other words, if we had a table A with a primary key X that linked to a table B where X was a field in B, then X would be a foreign key in B.

Alternate Key or Secondary

If any table have more than one candidate key, then after choosing primary key from those candidate key, rest of candidate keys are known as an alternate key of that table. Like here we can take a very simple example to understand the concept of alternate key. Suppose we have a table named Employee which has two columns EmpID and EmpMail, both have not null attributes and unique value. So both columns are treated as candidate key. Now we make EmpID as a primary key to that table then EmpMail is known as alternate key.

Composite Key

When we create keys on more than one column then that key is known as composite key. Like here we can take an example to understand this feature. I have a table Student which has two columns Sid and SrefNo and we make primary key on these two column. Then this key is known as composite key.

Natural keys

A natural key is one or more existing data attributes that are unique to the business concept. For the Customer table there was two candidate keys, in this case CustomerNumber and SocialSecurityNumber. Link http://www.agiledata.org/essays/keys.html

Surrogate key

Introduce a new column, called a surrogate key, which is a key that has no business meaning. An example of which is the AddressID column of the Address table in Figure 1. Addresses don't have an "easy" natural key because you would need to use all of the columns of the Address table to form a key for itself (you might be able to get away with just the combination of Street and ZipCode depending on your problem domain), therefore introducing a surrogate key is a much better option in this case. Link http://www.agiledata.org/essays/keys.html

Unique key

A unique key is a superkey--that is, in the relational model of database organization, a set of attributes of a relation variable for which it holds that in all relations assigned to that variable, there are no two distinct tuples (rows) that have the same values for the attributes in this set

Aggregate or Compound keys

When more than one column is combined to form a unique key, their combined value is used to access each row and maintain uniqueness. These keys are referred to as aggregate or compound keys. Values are not combined, they are compared using their data types.

Simple key

Simple key made from only one attribute.

Super key

A superkey is defined in the relational model as a set of attributes of a relation variable (relvar) for which it holds that in all relations assigned to that variable there are no two distinct tuples (rows) that have the same values for the attributes in this set. Equivalently a super key can also be defined as a set of attributes of a relvar upon which all attributes of the relvar are functionally dependent.

Partial Key or Discriminator key

It is a set of attributes that can uniquely identify weak entities and that are related to same owner entity. It is sometime called as Discriminator.

Not sure if it helps, but it looks like there might be a library for async iteration in node hosted here:

https://github.com/caolan/async

Async is a utility module which provides straight-forward, powerful functions for working with asynchronous JavaScript. Although originally designed for use with node.js, it can also be used directly in the browser.

Async provides around 20 functions that include the usual 'functional' suspects (map, reduce, filter, forEach…) as well as some common patterns for asynchronous control flow (parallel, series, waterfall…). All these functions assume you follow the node.js convention of providing a single callback as the last argument of your async function.

Some APIs want you to supply the appropriate "Accept" header in the request to get the wanted response type.

For example if an API can return data in XML and JSON and you want the JSON result, you would need to set the HttpWebRequest.Accept property to "application/json".

HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(requestUri);
httpWebRequest.Method = WebRequestMethods.Http.Get;
httpWebRequest.Accept = "application/json";

 function convertDatePickerTimeToMySQLTime(str) {
        var month, day, year, hours, minutes, seconds;
        var date = new Date(str),
            month = ("0" + (date.getMonth() + 1)).slice(-2),
            day = ("0" + date.getDate()).slice(-2);
        hours = ("0" + date.getHours()).slice(-2);
        minutes = ("0" + date.getMinutes()).slice(-2);
        seconds = ("0" + date.getSeconds()).slice(-2);

        var mySQLDate = [date.getFullYear(), month, day].join("-");
        var mySQLTime = [hours, minutes, seconds].join(":");
        return [mySQLDate, mySQLTime].join(" ");
    }
