Daniel Farrell's Bootstrap Combobox does the job perfectly. Here's an example from his GitHub repository.

$(document).ready(function(){_x000D_
  $('.combobox').combobox();_x000D_
  _x000D_
  // bonus: add a placeholder_x000D_
  $('.combobox').attr('placeholder', 'For example, start typing "Pennsylvania"');_x000D_
});

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.7/css/bootstrap.min.css">_x000D_
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-combobox/1.1.8/css/bootstrap-combobox.min.css">_x000D_

_x000D_
<select class="combobox form-control">_x000D_
  <option></option>_x000D_
  <option value="PA">Pennsylvania</option>_x000D_
  <option value="CT">Connecticut</option>_x000D_
  <option value="NY">New York</option>_x000D_
  <option value="MD">Maryland</option>_x000D_
  <option value="VA">Virginia</option>_x000D_
</select>

As an added bonus, I've included a placeholder in script since applying it to the markup does not hold.

Even when I just had one writer and one reader, my issue was that one of the reads was taking too long: longer than the stipulated timeout of 5 seconds. So the writer timed out and caused the error.

So, be careful when reading all entries from a database especially from one which the size of the table grows over time.

I think op wants to know what the font that is used on a webpage is, and hoped that info might be findable in the 'inspect' pane.

Try adding the Whatfont Chrome extension.

There are other options for you to benchmark:

1.) A window function will return the actual size directly (tested in MariaDB):

SELECT 
  `mytable`.*,
  COUNT(*) OVER() AS `total_count`
FROM `mytable`
ORDER BY `mycol`
LIMIT 10, 20

2.) Thinking out of the box, most of the time users don't need to know the EXACT size of the table, an approximate is often good enough.

SELECT `TABLE_ROWS` AS `rows_approx`
FROM `INFORMATION_SCHEMA`.`TABLES`
WHERE `TABLE_SCHEMA` = DATABASE()
  AND `TABLE_TYPE` = "BASE TABLE"
  AND `TABLE_NAME` = ?

Note that WebMvcConfigurerAdapter is deprecated now (see WebMvcConfigurerAdapter). Due to Java 8 default methods, you only have to implement WebMvcConfigurer.

You can use jQuery change() function

$('input').change(function(){
  //your codes
});

There are examples on how to use it on the API Page: http://api.jquery.com/change/

Try calling it like: obj.some_function( '1', 2, '3', g="foo", h="bar" ). After the required positional arguments, you can specify specific optional arguments by name.

There are two solutions for it.

Solution number one: 1.Recreate the project. While creating a project ensure that precompiled header is checked(Application settings... *** Do not check empty project)

Solution Number two: 1.Create stdafx.h and stdafx.cpp in your project 2 Right click on project -> properties -> C/C++ -> Precompiled Headers 3.select precompiled header to create(/Yc) 4.Rebuild the solution

Drop me a message if you encounter any issue.

You can fetch and then check out only one file in this way:

git fetch
git checkout -m <revision> <yourfilepath>
git add <yourfilepath>
git commit

Regarding the git checkout command:

• <revision> -- a branch name, i.e. origin/master
• <yourfilepath> does not include the repository name (that you can get from clicking copy path button on a file page on GitHub), i.e. README.md

If you need to use integers of certain length, you probably should use some platform independent headers to help you. Boost is a good place to look at.

Does m really need to be a data.frame() or will a matrix() suffice?

m <- matrix(0, ncol = 30, nrow = 2)

You can wrap a data.frame() around that if you need to:

m <- data.frame(m)

or all in one line: m <- data.frame(matrix(0, ncol = 30, nrow = 2))

Spread operator

The spread operator allows an expression to be expanded in places where multiple arguments (for function calls) or multiple elements (for array literals) are expected.

ECMAScript ES6 added a new operator that lets you do this in a more practical way: ...Spread Operator.

Example without using the apply method:

function a(...args){_x000D_
  b(...args);_x000D_
  b(6, ...args, 8) // You can even add more elements_x000D_
}_x000D_
function b(){_x000D_
  console.log(arguments)_x000D_
}_x000D_
_x000D_
a(1, 2, 3)

Note This snippet returns a syntax error if your browser still uses ES5.

^{Editor's note: Since the snippet uses console.log(), you must open your browser's JS console to see the result - there will be no in-page result.}

It will display this result:

In short, the spread operator can be used for different purposes if you're using arrays, so it can also be used for function arguments, you can see a similar example explained in the official docs: Rest parameters

For those looking for an example of how to pass the OAuth2 authorization (access token) in the header (as opposed to using a request or body parameter), here is how it's done:

Authorization: Bearer 0b79bab50daca910b000d4f1a2b675d604257e42

You are missing the ? in the second URL (Also, it should be URL-encoded to be %3F).

Also, I believe that the remaining & need to be URL, not HTML-encoded. Change &second=12&third=5 to %26second=12%26third=5 and everything should just work.

This:

&u=http://www.foobar.com/first=12&sec=25&position=2

should be:

&u=http://www.foobar.com/%3Ffirst=12%26sec=25%26position=2

You need to specify an access modifier for your variable. In this case you want it public.

public class Variables
{
    public static string name = "";
}

After this you can use the variable like this.

Variables.name

There are a few things wrong here:

• First, terminology. "Epoch" refers to the starting point of something. The "Unix Epoch" is Midnight, January 1st 1970 UTC. You can't convert an arbitrary "date string to epoch". You probably meant "Unix Time", which is often erroneously called "Epoch Time".

• .unix() returns Unix Time in whole seconds, but the default moment constructor accepts a timestamp in milliseconds. You should instead use .valueOf() to return milliseconds. Note that calling .unix()*1000 would also work, but it would result in a loss of precision.

• You're parsing a string without providing a format specifier. That isn't a good idea, as values like 1/2/2014 could be interpreted as either February 1st or as January 2nd, depending on the locale of where the code is running. (This is also why you get the deprecation warning in the console.) Instead, provide a format string that matches the expected input, such as:

  moment("10/15/2014 9:00", "M/D/YYYY H:mm")
  

• .calendar() has a very specific use. If you are near to the date, it will return a value like "Today 9:00 AM". If that's not what you expected, you should use the .format() function instead. Again, you may want to pass a format specifier.

• To answer your questions in comments, No - you don't need to call .local() or .utc().

Putting it all together:

var ts = moment("10/15/2014 9:00", "M/D/YYYY H:mm").valueOf();
var m = moment(ts);
var s = m.format("M/D/YYYY H:mm");
alert("Values are: ts = " + ts + ", s = " + s);

On my machine, in the US Pacific time zone, it results in:

Values are: ts = 1413388800000, s = 10/15/2014 9:00

Since the input value is interpreted in terms of local time, you will get a different value for ts if you are in a different time zone.

Also note that if you really do want to work with whole seconds (possibly losing precision), moment has methods for that as well. You would use .unix() to return the timestamp in whole seconds, and moment.unix(ts) to parse it back to a moment.

var ts = moment("10/15/2014 9:00", "M/D/YYYY H:mm").unix();
var m = moment.unix(ts);

The Eclipse UI is a little bit confusing.

The Import -> "Existing projects into workspace" actually means import "Existing Eclipse projects into workspace". That's why you can't click on finish: the import option looks for a .project file (the file used by Eclipse to store the project options) in the directory that you have chosen.

To import existing source code that doesn't have an Eclipse project file you have the following options (I suppose that you want to create a Java project):

1. New project inside the workspace dir: Create a new empty Java project into the workspace (File->New->Java Project). Then right click on the source folder and choose Import...->General->File system then choose your files, and it will make a copy of your files.

   Tip: you can drag&drop your files from the Finder into the src folder.

2. Create an eclipse project in your existing dir: Create a new Java project, but in the "New Java Project" window:

   • Un check the Use default location option, and choose the directory where is your non-Eclipse project.
   • Click Next and configure the sub-directories of your non-Eclipse project where the source files are located. And you are done :)

git diff > patchfile

and

patch -p1 < patchfile

work but as many people noticed in comments and other answers patch does not understand adds, deletes and renames. There is no option but git apply patchfile if you need handle file adds, deletes and renames.

EDIT December 2015

Latest versions of patch command (2.7, released in September 2012) support most features of the "diff --git" format, including renames and copies, permission changes, and symlink diffs (but not yet binary diffs) (release announcement).

So provided one uses current/latest version of patch there is no need to use git to be able to apply its diff as a patch.

What Google(search bot) needs is same content should be served to bot as it is served to user. Indenting text away (any text) gets bot to think it is a spam or you are serving different content to user and bot.

The best method is to directly use logo as an image inside your anchor tag. Give an 'alt' to your image. This will be perfect for bot to read & also will help in image searching.

I'm a PHP developer and to be able to work on my development environment with a certificate, I was able to do the same by finding the real SSL HTTPS/HTTP Certificate and deleting it.

The steps are :

1. In the address bar, type "chrome://net-internals/#hsts".
2. Type the domain name in the text field below "Delete domain".
3. Click the "Delete" button.
4. Type the domain name in the text field below "Query domain".
5. Click the "Query" button.
6. Your response should be "Not found".

Although this solution is not the best, Chrome currently does not have any good solution for the moment. I have escalated this situation with their support team to help improve user experience.

Edit : you have to repeat the steps every time you will go on the production site.

Save the count as you go - and use validation to enforce it. I hacked this together - for keeping a count of unique votes and counts which keeps coming up!. But this time I have tested my suggestion! (notwithstanding cut/paste errors!).

The 'trick' here is to use the node priority to as the vote count...

The data is:

vote/$issueBeingVotedOn/user/$uniqueIdOfVoter = thisVotesCount, priority=thisVotesCount vote/$issueBeingVotedOn/count = 'user/'+$idOfLastVoter, priority=CountofLastVote

,"vote": {
  ".read" : true
  ,".write" : true
  ,"$issue" : {
    "user" : {
      "$user" : {
        ".validate" : "!data.exists() && 
             newData.val()==data.parent().parent().child('count').getPriority()+1 &&
             newData.val()==newData.GetPriority()" 

user can only vote once && count must be one higher than current count && data value must be same as priority.

      }
    }
    ,"count" : {
      ".validate" : "data.parent().child(newData.val()).val()==newData.getPriority() &&
             newData.getPriority()==data.getPriority()+1 "
    }

count (last voter really) - vote must exist and its count equal newcount, && newcount (priority) can only go up by one.

  }
}

Test script to add 10 votes by different users (for this example, id's faked, should user auth.uid in production). Count down by (i--) 10 to see validation fail.

<script src='https://cdn.firebase.com/v0/firebase.js'></script>
<script>
  window.fb = new Firebase('https:...vote/iss1/');
  window.fb.child('count').once('value', function (dss) {
    votes = dss.getPriority();
    for (var i=1;i<10;i++) vote(dss,i+votes);
  } );

function vote(dss,count)
{
  var user='user/zz' + count; // replace with auth.id or whatever
  window.fb.child(user).setWithPriority(count,count);
  window.fb.child('count').setWithPriority(user,count);
}
</script>

The 'risk' here is that a vote is cast, but the count not updated (haking or script failure). This is why the votes have a unique 'priority' - the script should really start by ensuring that there is no vote with priority higher than the current count, if there is it should complete that transaction before doing its own - get your clients to clean up for you :)

The count needs to be initialised with a priority before you start - forge doesn't let you do this, so a stub script is needed (before the validation is active!).

Yet another way. You could use build_absolute_uri() in your view.py and pass it to the template.

view.py

def index(request):
    baseurl = request.build_absolute_uri()
    return render_to_response('your-template.html', { 'baseurl': baseurl })

your-template.html

{{ baseurl }}

What you want to do is called "serialization". There are several ways of doing it, but if you don't need anything fancy I think using the standard Java object serialization would do just fine.

Perhaps you could use something like this?

package com.example;

import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;

public class Serializer {

    public static byte[] serialize(Object obj) throws IOException {
        try(ByteArrayOutputStream b = new ByteArrayOutputStream()){
            try(ObjectOutputStream o = new ObjectOutputStream(b)){
                o.writeObject(obj);
            }
            return b.toByteArray();
        }
    }

    public static Object deserialize(byte[] bytes) throws IOException, ClassNotFoundException {
        try(ByteArrayInputStream b = new ByteArrayInputStream(bytes)){
            try(ObjectInputStream o = new ObjectInputStream(b)){
                return o.readObject();
            }
        }
    }

}

There are several improvements to this that can be done. Not in the least the fact that you can only read/write one object per byte array, which might or might not be what you want.

Note that "Only objects that support the java.io.Serializable interface can be written to streams" (see java.io.ObjectOutputStream).

Since you might run into it, the continuous allocation and resizing of the java.io.ByteArrayOutputStream might turn out to be quite the bottle neck. Depending on your threading model you might want to consider reusing some of the objects.

For serialization of objects that do not implement the Serializable interface you either need to write your own serializer, for example using the read*/write* methods of java.io.DataOutputStream and the get*/put* methods of java.nio.ByteBuffer perhaps together with reflection, or pull in a third party dependency.

This site has a list and performance comparison of some serialization frameworks. Looking at the APIs it seems Kryo might fit what you need.

You could also pass a dict to the pandas.replace method:

data.replace({
    'column_name': {
        'value_to_replace': 'replace_value_with_this'
    }
})

This has the advantage that you can replace multiple values in multiple columns at once, like so:

data.replace({
    'column_name': {
        'value_to_replace': 'replace_value_with_this',
        'foo': 'bar',
        'spam': 'eggs'
    },
    'other_column_name': {
        'other_value_to_replace': 'other_replace_value_with_this'
    },
    ...
})

You're missing a return statement.

When the compiler looks at your code, it's sees a third path (the else you didn't code for) that could occur but doesn't return a value. Hence not all code paths return a value.

For my suggested fix, I put a return after your loop ends. The other obvious spot - adding an else that had a return value to the if-else-if - would break the for loop.

public static bool isTwenty(int num)
{
    for(int j = 1; j <= 20; j++)
    {
        if(num % j != 0)
        {
            return false;
        }
        else if(num % j == 0 && num == 20)
        {
            return true;
        }
    }
    return false;  //This is your missing statement
}

Another example for ignoring multiple tables

/usr/bin/mysqldump -uUSER -pPASS --ignore-table={db_test.test1,db_test.test3} db_test> db_test.sql

using --ignore-table and create an array of tables, with syntaxs like

--ignore-table={db_test.table1,db_test.table3,db_test.table4}

Extra:

Import database

 # if file is .sql
 mysql -uUSER  -pPASS db_test < backup_database.sql
 # if file is .sql.gz
 gzip -dc < backup_database.sql.gz | mysql -uUSER -pPASSWORD db_test

Simple script to ignore tables and export in .sql.gz to save space

#!/bin/bash

#tables to ignore
_TIGNORE=(
my_database.table1
my_database.table2
my_database.tablex
)

#create text for ignore tables
_TDELIMITED="$(IFS=" "; echo "${_TIGNORE[*]/#/--ignore-table=}")"

#don't forget to include user and password
/usr/bin/mysqldump -uUSER -pPASSWORD --events ${_TDELIMITED} --databases my_database | gzip -v > backup_database.sql.gz

if you getting this type of error so I suggest you used to stored proc data as usual list then binding the other controls because I also get this error so I solved it like this ex:-

repeater.DataSource = data.SPBinsReport().Tolist();
repeater.DataBind();

try like this

Sometimes you can play with padding and margin top, add line-height, etc.

See fiddle.

Style and text forked from @aspirinemaga

.parent
{
    width:300px;
    line-height:30px;
    border:1px solid red;
    padding-top:20px;
}

Store it in the database in a field with a data type of uniqueidentifier.

<i class="fa" v-bind:class="cravings"></i>

and add in computed :

computed: {
    cravings: function() {
        return this.content['cravings'] ? 'fa-checkbox-marked' : 'fa-checkbox-blank-outline';
    }
}

Here is your answer. We can use both simultaniously. As i used both and they are working fine. The code is as follows:

<EditText
    android:id="@+id/edittext_password_la"
    android:layout_below="@+id/edittext_username_la"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_margin="15dip"
    android:inputType="textPassword"
    android:hint="@string/string_password" />

This will help you.

You can use the inbuilt function max() with multiple arguments:

print max(1, 2, 3)

or a list:

list = [1, 2, 3]
print max(list)

or in fact anything iterable.

If you need some es6 improvements not supported by Typescript, you can target es6 in your tsconfig and use Babel to convert your files in es5.

ResultSet rs = statement.executeQuery("select * from foo where value = " + httpRequest.getParameter("filter");

Let’s assume you have that in a Servlet you right. If a malevolent person passed a bad value for 'filter' you might hack your database.

What Triggers ANR?

Generally, the system displays an ANR if an application cannot respond to user input.

In any situation in which your app performs a potentially lengthy operation, you should not perform the work on the UI thread, but instead create a worker thread and do most of the work there. This keeps the UI thread (which drives the user interface event loop) running and prevents the system from concluding that your code has frozen.

How to Avoid ANRs

Android applications normally run entirely on a single thread by default the "UI thread" or "main thread"). This means anything your application is doing in the UI thread that takes a long time to complete can trigger the ANR dialog because your application is not giving itself a chance to handle the input event or intent broadcasts.

Therefore, any method that runs in the UI thread should do as little work as possible on that thread. In particular, activities should do as little as possible to set up in key life-cycle methods such as onCreate() and onResume(). Potentially long running operations such as network or database operations, or computationally expensive calculations such as resizing bitmaps should be done in a worker thread (or in the case of databases operations, via an asynchronous request).

Code: Worker thread with the AsyncTask class

private class DownloadFilesTask extends AsyncTask<URL, Integer, Long> {
    // Do the long-running work in here
    protected Long doInBackground(URL... urls) {
        int count = urls.length;
        long totalSize = 0;
        for (int i = 0; i < count; i++) {
            totalSize += Downloader.downloadFile(urls[i]);
            publishProgress((int) ((i / (float) count) * 100));
            // Escape early if cancel() is called
            if (isCancelled()) break;
        }
        return totalSize;
    }

    // This is called each time you call publishProgress()
    protected void onProgressUpdate(Integer... progress) {
        setProgressPercent(progress[0]);
    }

    // This is called when doInBackground() is finished
    protected void onPostExecute(Long result) {
        showNotification("Downloaded " + result + " bytes");
    }
}

Code: Execute Worker thread

To execute this worker thread, simply create an instance and call execute():

new DownloadFilesTask().execute(url1, url2, url3);

To get the namespace in its namespace format, e.g. {myNameSpace}, you can do the following:

root = tree.getroot()
ns = re.match(r'{.*}', root.tag).group(0)

This way, you can use it later on in your code to find nodes, e.g using string interpolation (Python 3).

link = root.find(f"{ns}link")

From the documentation I get the impression that in your example it would be intended to use:

@Range(min= SEQ_MIN_VALUE, max= SEQ_MAX_VALUE)

Checks whether the annotated value lies between (inclusive) the specified minimum and maximum. Supported data types:

BigDecimal, BigInteger, CharSequence, byte, short, int, long and the respective wrappers of the primitive types

You can set up a background with your GIF file and set the body this way:

body{
background-image:url('http://www.example.com/yourfile.gif');
background-position: center;
background-size: cover;
}

Change background image URL with your GIF. With background-position: center you can put the image to the center and with background-size: cover you set the picture to fit all the screen. You can also set background-size: contain if you want to fit the picture at 100% of the screen but without leaving any part of the picture without showing.

Here's more info about the property:

Hope it helps :)

... right now it happens only to the website I'm testing. I can't post it here because it's confidential.

Then I guess it is one of the sites which is incompatible with TLS1.2. The openssl as used in 12.04 does not use TLS1.2 on the client side while with 14.04 it uses TLS1.2 which might explain the difference. To work around try to explicitly use --secure-protocol=TLSv1. If this does not help check if you can access the site with openssl s_client -connect ... (probably not) and with openssl s_client -tls1 -no_tls1_1, -no_tls1_2 ....

Please note that it might be other causes, but this one is the most probable and without getting access to the site everything is just speculation anyway.

The assumed problem in detail: Usually clients use the most compatible handshake to access a server. This is the SSLv23 handshake which is compatible to older SSL versions but announces the best TLS version the client supports, so that the server can pick the best version. In this case wget would announce TLS1.2. But there are some broken servers which never assumed that one day there would be something like TLS1.2 and which refuse the handshake if the client announces support for this hot new version (from 2008!) instead of just responding with the best version the server supports. To access these broken servers the client has to lie and claim that it only supports TLS1.0 as the best version.

Is Ubuntu 14.04 or wget 1.15 not compatible with TLS 1.0 websites? Do I need to install/download any library/software to enable this connection?

The problem is the server, not the client. Most browsers work around these broken servers by retrying with a lower version. Most other applications fail permanently if the first connection attempt fails, i.e. they don't downgrade by itself and one has to enforce another version by some application specific settings.

Problems

The code has the following issues:

• An Ajax call (<a4j:commandButton .../>) does not work with attachments.
• Creating the output content must happen first.
• Displaying the error messages also cannot use Ajax-based a4j tags.

Solution

1. Change <a4j:commandButton .../> to <h:commandButton .../>.
2. Update the source code:
   1. Change bw.write( getDomainDocument() ); to bw.write( document );.
   2. Add String document = getDomainDocument(); to the first line of the try/catch.
3. Change the <a4j:outputPanel.../> (not shown) to <h:messages showDetail="false"/>.

Essentially, remove all the Ajax facilities related to the commandButton. It is still possible to display error messages and leverage the RichFaces UI style.

I'd highly suggest you use this instead of creating the animation file because it's a much better solution. Android Studio already provides default animation you can use without creating any new XML file. The animations' names are android.R.anim.slide_in_left and android.R.anim.slide_out_right and you can use them as follows:

fragmentTransaction.setCustomAnimations(android.R.anim.slide_in_left, android.R.anim.slide_out_right);

FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();              
fragmentTransaction.setCustomAnimations(android.R.anim.slide_in_left, android.R.anim.slide_out_right);
fragmentManager.addOnBackStackChangedListener(this);
fragmentTransaction.replace(R.id.frame, firstFragment, "h");
fragmentTransaction.addToBackStack("h");
fragmentTransaction.commit();

Output:

The header field name registry is defined in RFC3864, and there's nothing special with "X-".

As far as I can tell, there are no guidelines for private headers; in doubt, avoid them. Or have a look at the HTTP Extension Framework (RFC 2774).

It would be interesting to understand more of the use case; why can't the information be added to the message body?

It's an interesting question, because it shows that there are a lot of different approaches to achieve the same result. Below I show three different implementations.

Default methods in Collection Framework: Java 8 added some methods to the collections classes, that are not directly related to the Stream API. Using these methods, you can significantly simplify the implementation of the non-stream implementation:

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    Map<String, DataSet> result = new HashMap<>();
    multiDataPoints.forEach(pt ->
        pt.keyToData.forEach((key, value) ->
            result.computeIfAbsent(
                key, k -> new DataSet(k, new ArrayList<>()))
            .dataPoints.add(new DataPoint(pt.timestamp, value))));
    return result.values();
}

Stream API with flatten and intermediate data structure: The following implementation is almost identical to the solution provided by Stuart Marks. In contrast to his solution, the following implementation uses an anonymous inner class as intermediate data structure.

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .flatMap(mdp -> mdp.keyToData.entrySet().stream().map(e ->
            new Object() {
                String key = e.getKey();
                DataPoint dataPoint = new DataPoint(mdp.timestamp, e.getValue());
            }))
        .collect(
            collectingAndThen(
                groupingBy(t -> t.key, mapping(t -> t.dataPoint, toList())),
                m -> m.entrySet().stream().map(e -> new DataSet(e.getKey(), e.getValue())).collect(toList())));
}

Stream API with map merging: Instead of flattening the original data structures, you can also create a Map for each MultiDataPoint, and then merge all maps into a single map with a reduce operation. The code is a bit simpler than the above solution:

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .map(mdp -> mdp.keyToData.entrySet().stream()
            .collect(toMap(e -> e.getKey(), e -> asList(new DataPoint(mdp.timestamp, e.getValue())))))
        .reduce(new HashMap<>(), mapMerger())
        .entrySet().stream()
        .map(e -> new DataSet(e.getKey(), e.getValue()))
        .collect(toList());
}

You can find an implementation of the map merger within the Collectors class. Unfortunately, it is a bit tricky to access it from the outside. Following is an alternative implementation of the map merger:

<K, V> BinaryOperator<Map<K, List<V>>> mapMerger() {
    return (lhs, rhs) -> {
        Map<K, List<V>> result = new HashMap<>();
        lhs.forEach((key, value) -> result.computeIfAbsent(key, k -> new ArrayList<>()).addAll(value));
        rhs.forEach((key, value) -> result.computeIfAbsent(key, k -> new ArrayList<>()).addAll(value));
        return result;
    };
}

The CSS below stops users from being able to select text.

-webkit-user-select: none; /* Safari */        
-moz-user-select: none; /* Firefox */
-ms-user-select: none; /* IE10+/Edge */
user-select: none; /* Standard */

To target IE9 downwards the html attribute unselectable must be used instead:

<p unselectable="on">Test Text</p>

If the variable is not going to change you could use define

Example:

define('FOOTER_CONTENT', 'Hello I\'m an awesome footer!');

function footer()
{
    echo FOOTER_CONTENT;
}

If the browser people see this as a security and/or usability problem, then the answer to your question is to simply not close the window, since by definition they will come up with solutions for your workaround anyway. There is a nice summation about the reasoning why the choice have been in the firefox bug database https://bugzilla.mozilla.org/show_bug.cgi?id=190515#c70

That is, see it as a handoff to someone else that (potentially) needs it. As an example, Hanselman had a recent article about what to do in the other similar situation, namely 404 errors: http://www.hanselman.com/blog/PutMissingKidsOnYour404PageEntirelyClientSideSolutionWithYQLJQueryAndMSAjax.aspx

AndroidX is the open-source project that the Android team uses to develop, test, package, version and release libraries within Jetpack.

After hours of struggling, I solved it by including the following within app/build.gradle:

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

Put these flags in your gradle.properties

android.enableJetifier=true
android.useAndroidX=true

Changes in gradle:

implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'androidx.legacy:legacy-support-v4:1.0.0'
implementation 'com.google.android.material:material:1.1.0-alpha04'

When migrating on Android studio, the app/gradle file is automatically updated with the correction library impleemntations from the standard library

Refer to: https://developer.android.com/jetpack/androidx/migrate

If this is just going to open up the user's client to send the email, why not let them compose it there as well. You lose the ability to track what they are sending, but if that's not important, then just collect the addresses and subject and pop up the client to let the user fill in the body.

As part of htmlAttributes,e.g.

Html.BeginForm(
    action, controller, FormMethod.Post, new { enctype="multipart/form-data"})

Or you can pass null for action and controller to get the same default target as for BeginForm() without any parameters:

Html.BeginForm(
    null, null, FormMethod.Post, new { enctype="multipart/form-data"})

In case this helps anyone :

Check out CodingBat! It really helped me learn java way back when (although it used to be JavaBat back then). It's a lot like Codecademy.

as much as everyone hates tables for layout, they do help with stuff like this, either using explicit table tags or using display:table-cell

<div style="width:300px; display:table">
    <label for="MyInput" style="display:table-cell; width:1px">label&nbsp;text</label>
    <input type="text" id="MyInput" style="display:table-cell; width:100%" />
</div>

Sometimes changing the date format doesn't work properly, especially in Laravel. So in that case, it's better to use:

$date1 = strtr($_REQUEST['date'], '/', '-');
echo date('Y-m-d', strtotime($date1));

Then you can avoid error like "1970-01-01"!

HTTP/2 supports queries multiplexing, headers compression, priority and more intelligent packet streaming management. This results in reduced latency and accelerates content download on modern web pages.

After following the instructions in the other answers, I needed to strip the version from the map file for this to work for me.

Example: Rename

jquery-1.9.1.min.map

to

jquery.min.map

Not a specific answer to your question but I had got this error when I hadn't set an initial value for an enum while declaring it as a property. I assigned a initial value to the enum to resolve this error. Posting here as it might help someone.

Since Python 2.6.X you might want to use:

"my {0} string: {1}".format("cool", "Hello there!")

Your best bet is to create a new List<Customer>, iterate through the List<Object>, add each item to the new list, and return that.

Remove the date() part

SELECT name, datum 
FROM tasks 
WHERE datum >= NOW()

and if you use a specific date, don't forget the quotes around it and use the proper format with :

SELECT name, datum 
FROM tasks 
WHERE datum >= '2014-05-18 15:00:00'

I've spliced together the most elegant approaches to this utility method:

public static class Ux {
    public static decimal ToUnixTimestampSecs(this DateTime date) => ToUnixTimestampTicks(date) / (decimal) TimeSpan.TicksPerSecond;
    public static long ToUnixTimestampTicks(this DateTime date) => date.ToUniversalTime().Ticks - UnixEpochTicks;
    private static readonly long UnixEpochTicks = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc).Ticks;
}

To answer the underlying question of how to use a CASE expression in the WHERE clause:

First remember that the value of a CASE expression has to have a normal data type value, not a boolean value. It has to be a varchar, or an int, or something. It's the same reason you can't say SELECT Name, 76 = Age FROM [...] and expect to get 'Frank', FALSE in the result set.

Additionally, all expressions in a WHERE clause need to have a boolean value. They can't have a value of a varchar or an int. You can't say WHERE Name; or WHERE 'Frank';. You have to use a comparison operator to make it a boolean expression, so WHERE Name = 'Frank';

That means that the CASE expression must be on one side of a boolean expression. You have to compare the CASE expression to something. It can't stand by itself!

Here:

WHERE 
    DateDropped = 0
    AND CASE
            WHEN @JobsOnHold  = 1 AND DateAppr >= 0 THEN 'True'
            WHEN DateAppr != 0 THEN 'True'
            ELSE 'False'
        END = 'True'

Notice how in the end the CASE expression on the left will turn the boolean expression into either 'True' = 'True' or 'False' = 'True'.

Note that there's nothing special about 'False' and 'True'. You can use 0 and 1 if you'd rather, too.

You can typically rewrite the CASE expression into boolean expressions we're more familiar with, and that's generally better for performance. However, sometimes is easier or more maintainable to use an existing expression than it is to convert the logic.

For Me i got same issue i resolved like this changed format:'dd/mm/yy' to dateFormat: 'dd/mm/yy'

My simple solution:

import datetime

def months(d1, d2):
    return d1.month - d2.month + 12*(d1.year - d2.year)

d1 = datetime.datetime(2009, 9, 26)  
d2 = datetime.datetime(2019, 9, 26) 

print(months(d1, d2))

Recently I found that mistake happened not only in case when you forgot to import FormsModule in your module. In my case problem was in this code:

<input type="text" class="form-control" id="firstName"
                   formControlName="firstName" placeholder="Enter First Name"
                   value={{user.firstName}} [(ngModel)]="user.firstName">

I fix it with change formControlName -> name

<input type="text" class="form-control" id="firstName"
                   name="firstName" placeholder="Enter First Name"
                   value={{user.firstName}} [(ngModel)]="user.firstName">

Using regular expressions is costly in terms of performance. Trying to parse string as a long value is inefficient and unreliable, and may be not what you need.

What I suggest is to simply check if each character is a digit, what can be efficiently done using Java 8 lambda expressions:

boolean isNumeric = someString.chars().allMatch(x -> Character.isDigit(x));

ModelState.IsValid tells you if any model errors have been added to ModelState.

The default model binder will add some errors for basic type conversion issues (for example, passing a non-number for something which is an "int"). You can populate ModelState more fully based on whatever validation system you're using.

The sample DataAnnotations model binder will fill model state with validation errors taken from the DataAnnotations attributes on your model.

One of the other reason is , you should whitelist your IP address (IPv4) in your mongodb settings. Hope it resolves !

This is another way:

irb> [*1..10]

=> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

(Get-Item $source).LastWriteTime is my preferred way to do it.

Drop the hash - that's for identifying the id attribute.

Enumerable.SequenceEqual Method

Determines whether two sequences are equal according to an equality comparer. MS.Docs

Enumerable.SequenceEqual(list1, list2);

This works for all primitive data types. If you need to use it on custom objects you need to implement IEqualityComparer

Defines methods to support the comparison of objects for equality.

IEqualityComparer Interface

Defines methods to support the comparison of objects for equality. MS.Docs for IEqualityComparer

_{Additional details to the previous answer:}

While React's setState is asynchronous (both classes and hooks), and it's tempting to use that fact to explain the observed behavior, it is not the reason why it happens.

TLDR: The reason is a closure scope around an immutable const value.

Solutions:

• read the value in render function (not inside nested functions):

    useEffect(() => { setMovies(result) }, [])
    console.log(movies)
  

• add the variable into dependencies (and use the react-hooks/exhaustive-deps eslint rule):

    useEffect(() => { setMovies(result) }, [])
    useEffect(() => { console.log(movies) }, [movies])
  

• use a mutable reference (when the above is not possible):

    const moviesRef = useRef(initialValue)
    useEffect(() => {
      moviesRef.current = result
      console.log(moviesRef.current)
    }, [])
  

Explanation why it happens:

If async was the only reason, it would be possible to await setState().

However, both props and state are assumed to be unchanging during 1 render.

Treat this.state as if it were immutable.

With hooks, this assumption is enhanced by using constant values with the const keyword:

const [state, setState] = useState('initial')

The value might be different between 2 renders, but remains a constant inside the render itself and inside any closures (functions that live longer even after render is finished, e.g. useEffect, event handlers, inside any Promise or setTimeout).

Consider following fake, but synchronous, React-like implementation:

// sync implementation:

let internalState
let renderAgain

const setState = (updateFn) => {
  internalState = updateFn(internalState)
  renderAgain()
}

const useState = (defaultState) => {
  if (!internalState) {
    internalState = defaultState
  }
  return [internalState, setState]
}

const render = (component, node) => {
  const {html, handleClick} = component()
  node.innerHTML = html
  renderAgain = () => render(component, node)
  return handleClick
}

// test:

const MyComponent = () => {
  const [x, setX] = useState(1)
  console.log('in render:', x) // ?
  
  const handleClick = () => {
    setX(current => current + 1)
    console.log('in handler/effect/Promise/setTimeout:', x) // ? NOT updated
  }
  
  return {
    html: `<button>${x}</button>`,
    handleClick
  }
}

const triggerClick = render(MyComponent, document.getElementById('root'))
triggerClick()
triggerClick()
triggerClick()

<div id="root"></div>

The problem I sometimes have with the selected "Answer" is that the distribution isn't always even. If you need a very even distribution of random 1 - 14 among lots of rows, you can do something like this (my database has 511 tables, so this works. If you have less rows than you do random number span, this does not work well):

SELECT table_name, ntile(14) over(order by newId()) randomNumber 
FROM information_schema.tables

This kind of does the opposite of normal random solutions in the sense that it keeps the numbers sequenced and randomizes the other column.

Remember, I have 511 tables in my database (which is pertinent only b/c we're selecting from the information_schema). If I take the previous query and put it into a temp table #X, and then run this query on the resulting data:

select randomNumber, count(*) ct from #X
group by randomNumber

I get this result, showing me that my random number is VERY evenly distributed among the many rows:

Edit: I just noticed that you said you had already created some commits. In that case, use git merge --squash to make a single commit:

git checkout cleanchanges
git merge --squash master
git commit -m "nice commit comment for all my changes"

(Edit: The following answer applies if you have uncommitted changes.)

Just switch branches with git checkout cleanchanges. If the branches refer to the same ref, then all your uncommitted changes will be preserved in your working directory when you switch.

The only time you would have a conflict is if some file in the repository is different between origin/master and cleanchanges. If you just created the branch, then no problem.

As always, if you're at all concerned about losing work, make a backup copy first. Git is designed to not throw away work without asking you first.

You can try using AppDomain.UnhandledException and see if that lets you catch it.

**EDIT*

Here is some more information that might be useful (it's a long read).

Vertical align doesn't quite work the way you want it to. See: http://phrogz.net/css/vertical-align/index.html

This isn't pretty, but it WILL do what you want: Vertical align behaves as expected only when used in a table cell.

http://jsfiddle.net/e8ESb/6/

There are other alternatives: You can declare things as tables or table cells within CSS to make them behave as desired, for example. Margins and positioning can sometimes be played with to get the same effect. None of the solutions are terrible pretty, though.

In Python we can use the __str__() method.

We can override it in our class like this:

class User: 

    firstName = ''
    lastName = ''
    ...

    def __str__(self):
        return self.firstName + " " + self.lastName

and when running

print(user)

it will call the function __str__(self) and print the firstName and lastName

You can try jclasslib:

https://github.com/ingokegel/jclasslib

It's nice that it can associate itself with *.class extension.

Found easiest way for me. Here an example with fork for clarity that this way is useful for flow control.

import signal
import time
import sys
import os

def handle_exit(sig, frame):
    raise(SystemExit)

def main():
    time.sleep(120)

signal.signal(signal.SIGTERM, handle_exit)

p = os.fork()
if p == 0:
    main()
    os._exit()

try:
    os.waitpid(p, 0)
except (KeyboardInterrupt, SystemExit):
    print('exit handled')
    os.kill(p, 15)
    os.waitpid(p, 0)

For anybody who is getting an error like : '2*' string cannot be converted to Length.

The simplest method to bring a resource from the classpath in the resources directory parsed into a String is the following one liner.

As a String(Using Spring Libraries):

         String resource = StreamUtils.copyToString(
                new ClassPathResource("resource.json").getInputStream(), defaultCharset());

This method uses the StreamUtils utility and streams the file as an input stream into a String in a concise compact way.

If you want the file as a byte array you can use basic Java File I/O libraries:

As a byte array(Using Java Libraries):

byte[] resource = Files.readAllBytes(Paths.get("/src/test/resources/resource.json"));

The default behavior of os.walk() is to walk from root to leaf. Set topdown=False in os.walk() to walk from leaf to root.

Using bash:

echo "|${COMMAND/$'\n'}|"

^{(Note that the control character in this question is a 'newline' (\n), not a carriage return (\r); the latter would have output REBOOT| on a single line.)}

Explanation

Uses the Bash Shell Parameter Expansion ${parameter/pattern/string}:

The pattern is expanded to produce a pattern just as in filename expansion. Parameter is expanded and the longest match of pattern against its value is replaced with string. [...] If string is null, matches of pattern are deleted and the / following pattern may be omitted.

Also uses the $'' ANSI-C quoting construct to specify a newline as $'\n'. Using a newline directly would work as well, though less pretty:

echo "|${COMMAND/
}|"

Full example

#!/bin/bash
COMMAND="$'\n'REBOOT"
echo "|${COMMAND/$'\n'}|"
# Outputs |REBOOT|

Or, using newlines:

#!/bin/bash
COMMAND="
REBOOT"
echo "|${COMMAND/
}|"
# Outputs |REBOOT|

To change the text;

multipleLine.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            MainActivity.myArray.set(pickId,String.valueOf(s));
            MainActivity.myAdapt.notifyDataSetChanged();
        }

        @Override
        public void afterTextChanged(Editable s) {

        }

The issue for you is that you are using mm. You should use MM. MM is for month and mm is for minutes. Try with yyyy-MM-dd HH:mm

Other approach:

It can be as simple as this (other option is to use joda-time)

static final long ONE_MINUTE_IN_MILLIS=60000;//millisecs

Calendar date = Calendar.getInstance();
long t= date.getTimeInMillis();
Date afterAddingTenMins=new Date(t + (10 * ONE_MINUTE_IN_MILLIS));

Try

help(my_list)

to get built-in help messages.

The Esentutl /y option allows copyng (single) file files with progress bar like this :

the command should look like :

esentutl /y "FILE.EXT" /d "DEST.EXT" /o

The command is available on every windows machine but the y option is presented in windows vista. As it works only with single files does not look very useful for a small ones. Other limitation is that the command cannot overwrite files. Here's a wrapper script that checks the destination and if needed could delete it (help can be seen by passing /h).

Double backslash also works ! Then you declare there really should be a / instead of some function or something.

<script>document.write('<script src="…"><//script>');</script>

You can chain class selectors without a space between them:

.a.b {
     color: #666;
}

Note that, if it matters to you, IE6 treats .a.b as .b, so in that browser both div.a.b and div.b will have gray text. See this answer for a comparison between proper browsers and IE6.

Since version 21, Guava library provides Streams.stream(iterator)

    null, /* origin is 0,0 */
    null, /* anchor is bottom center of the scaled image */

I think you probably want to view the minification of each set of css as a separate task

task minifyBrandACss(type: com.eriwen.gradle.css.tasks.MinifyCssTask) {
     source = "src/main/webapp/css/brandA/styles.css"
     dest = "${buildDir}/brandA/styles.css"
}

etc etc

BTW executing your minify tasks in an action of the war task seems odd to me - wouldn't it make more sense to make them a dependency of the war task?

I've always done it with sed

  var=`hg st -R "$path" | sed -e 's/  *$//'`

If there is a more elegant solution, I hope somebody posts it.

First off, are you setting your desired JRE or your desired JDK?

Even if your Eclipse is set up properly, there might be a wacky project-specific setting somewhere. You can open up a context menu on a given Java project in the Project Explorer and select Properties > Java Compiler to check on that.

If none of that helps, leave a comment and I'll take another look.

nVarchar2 is a Unicode-only storage.

Though both data types are variable length String datatypes, you can notice the difference in how they store values. Each character is stored in bytes. As we know, not all languages have alphabets with same length, eg, English alphabet needs 1 byte per character, however, languages like Japanese or Chinese need more than 1 byte for storing a character.

When you specify varchar2(10), you are telling the DB that only 10 bytes of data will be stored. But, when you say nVarchar2(10), it means 10 characters will be stored. In this case, you don't have to worry about the number of bytes each character takes.

copy your Json and paste at textbox on http://json2csharp.com/ and click on Generate button,

A cs class will be generated use that cs file as below:

var generatedcsResponce = JsonConvert.DeserializeObject(yourJson);

where RootObject is the name of the generated cs file;

You didn't say on which event.Just use below on your event listener.Or in your page load

$('#models').empty()

Then to repopulate

$.getJSON('@Url.Action("YourAction","YourController")',function(data){
 var dropdown=$('#models');
dropdown.empty();  
$.each(data, function (index, item) {
    dropdown.append(
        $('<option>', {
            value: item.valueField,
            text: item.DisplayField
        }, '</option>'))
      }
     )});

I find it more convenient to make a connection using a procedural programming language (like Python) and do these types of queries.

import psycopg2
connection_psql = psycopg2.connect( user="admin_user"
                                  , password="***"
                                  , port="5432"
                                  , database="myDB"
                                  , host="[ENDPOINT]")
cursor_psql = connection_psql.cursor()

myList = [...]
for item in myList:
  cursor_psql.execute('''
    -- The query goes here
  ''')

connection_psql.commit()
cursor_psql.close()

We can add ng-click event conditionally without using disabled class.

HTML:

<div ng-repeat="object in objects">
<span ng-click="!object.status && disableIt(object)">{{object.value}}</span>
</div>

I also faced this same issue, I got a solution with this.

I did the following steps :

1. Open system properties
2. Environment variables
3. create a new system variable
4. name: ANDROID_HOME
5. value: copy your SDK path( Ex: my SDK path E:\SoftWares\Android-SDK)

close your current cmd, and restart it run flutter doctor

this should work on windows

For me <td class="align-middle" >${element.imie}</td> works. I'm using Bootstrap v4.0.0-beta .

Your code isn't working, because the hidden attibute is not supported in versions of IE before v11

If you need to support IE before version 11, add a CSS style to hide when the hidden attribute is present:

*[hidden] { display: none; }

Here is my solution:

/^(2[0-9]{3})-(0[1-9]|1[012])-(0[1-9]|[12][0-9]|3[01]) (0[0-9]|1[0-9]|2[0123])\:([012345][0-9])\:([012345][0-9])$/u

EDIT : now that I know better

Using regexp to solve this kind of problem is a bad idea and will likely lead in unmaintainable and unreliable code. Better use an HTML parser.

Solution With regexp

In that case it's better to split the process into two parts :

• get all the img tag
• extract their metadata

I will assume your doc is not xHTML strict so you can't use an XML parser. E.G. with this web page source code :

/* preg_match_all match the regexp in all the $html string and output everything as 
an array in $result. "i" option is used to make it case insensitive */

preg_match_all('/<img[^>]+>/i',$html, $result); 

print_r($result);
Array
(
    [0] => Array
        (
            [0] => <img src="/Content/Img/stackoverflow-logo-250.png" width="250" height="70" alt="logo link to homepage" />
            [1] => <img class="vote-up" src="/content/img/vote-arrow-up.png" alt="vote up" title="This was helpful (click again to undo)" />
            [2] => <img class="vote-down" src="/content/img/vote-arrow-down.png" alt="vote down" title="This was not helpful (click again to undo)" />
            [3] => <img src="http://www.gravatar.com/avatar/df299babc56f0a79678e567e87a09c31?s=32&d=identicon&r=PG" height=32 width=32 alt="gravatar image" />
            [4] => <img class="vote-up" src="/content/img/vote-arrow-up.png" alt="vote up" title="This was helpful (click again to undo)" />

[...]
        )

)

Then we get all the img tag attributes with a loop :

$img = array();
foreach( $result as $img_tag)
{
    preg_match_all('/(alt|title|src)=("[^"]*")/i',$img_tag, $img[$img_tag]);
}

print_r($img);

Regexps are CPU intensive so you may want to cache this page. If you have no cache system, you can tweak your own by using ob_start and loading / saving from a text file.

How does this stuff work ?

First, we use preg_ match_ all, a function that gets every string matching the pattern and ouput it in it's third parameter.

The regexps :

<img[^>]+>

We apply it on all html web pages. It can be read as every string that starts with "<img", contains non ">" char and ends with a >.

(alt|title|src)=("[^"]*")

We apply it successively on each img tag. It can be read as every string starting with "alt", "title" or "src", then a "=", then a ' " ', a bunch of stuff that are not ' " ' and ends with a ' " '. Isolate the sub-strings between ().

Finally, every time you want to deal with regexps, it handy to have good tools to quickly test them. Check this online regexp tester.

EDIT : answer to the first comment.

It's true that I did not think about the (hopefully few) people using single quotes.

Well, if you use only ', just replace all the " by '.

If you mix both. First you should slap yourself :-), then try to use ("|') instead or " and [^ø] to replace [^"].

This q/a shows how to use find with regular expression: How to use regex with find command?

Pattern could be something like

'^Robert\\.\\(h|cgg\\)$'

The following 2 commands worked for me:

git archive --remote={remote_repo_git_url} {branch} {file_to_download} -o {tar_out_file}

Downloads file_to_download as tar archive from branch of remote repository whose url is remote_repo_git_url and stores it in tar_out_file

tar -x -f {tar_out_file}.tar extracts the file_to_download from tar_out_file

You can write like below. Check out the syntax guidelines in this thread

AClass[] array;
...
array = new AClass[]{object1, object2};

If you find arrays annoying better use ArrayList.

Codeproject has a complete solution for this:

http://www.codeproject.com/Articles/17241/Capturing-the-Enter-key-to-cause-a-button-click

and like the article says: "decide which solution best fits your needs"

=================== EDITED ANSWER ============================

The link mentioned above, talks about two ways of capturing the "Enter Key" event:

Javascript (bind the onKeyPress event to the object and create a javascript function to check which key was pressed and do your logic)

_Page_Load in code behind:_

 //Add the javascript so we know where we want the enter key press to go
if (!IsPostBack)
{
   txtboxFirstName.Attributes.Add("onKeyPress", 
                   "doClick('" + btnSearch.ClientID + "',event)");
   txtboxLastName.Attributes.Add("onKeyPress", 
                  "doClick('" + btnSearch.ClientID + "',event)");
}

Javascript code:

<SCRIPT type=text/javascript>
    function doClick(buttonName,e)
    {
        //the purpose of this function is to allow the enter key to 
        //point to the correct button to click.
        var key;

         if(window.event)
              key = window.event.keyCode;     //IE
         else
              key = e.which;     //firefox

        if (key == 13)
        {
            //Get the button the user wants to have clicked
            var btn = document.getElementById(buttonName);
            if (btn != null)
            { //If we find the button click it
                btn.click();
                event.keyCode = 0
            }
        }
   }
</SCRIPT>

Panel Control

<asp:Panel ID="panSearch" runat="server" DefaultButton="btnSearch2" Width="100%" >
    <asp:TextBox ID="txtboxFirstName2" runat="server" ></asp:TextBox>
</asp:Panel>

Quoting:

Notice that the Panel tag has a property called DefaultButton. You set this property to the button ID of the button you want to be clicked on an Enter key press event. So any text box inside of the Panel will direct its Enter key press to the button set in the DefaultButton property of the Panel

The ng-model attribute sets the selected option and also allows you to pipe a filter like orderBy:orderModel.value

index.html

<select ng-model="orderModel" ng-options="option.name for option in orderOptions"></select>

controllers.js

$scope.orderOptions = [
    {"name":"Newest","value":"age"},
    {"name":"Alphabetical","value":"name"}
];

$scope.orderModel = $scope.orderOptions[0];

You can trick it. Remove the file element and add it in the same place on change event. It will erase the file path making it changeable every time.

Example on jsFiddle.

Or you can simply use .prop("value", ""), see this example on jsFiddle.

• jQuery 1.6+ prop
• Earlier versions attr

l = [1, 2, 3, 4, 5]
del l[0:3] # Here 3 specifies the number of items to be deleted.

This is the code if you want to delete a number of items from the list. You might as well skip the zero before the colon. It does not have that importance. This might do as well.

l = [1, 2, 3, 4, 5]
del l[:3] # Here 3 specifies the number of items to be deleted.

This is more of a important comment and that why implicitly unwrapped optionals can be deceptive when it comes to debugging nil values.

Think of the following code: It compiles with no errors/warnings:

c1.address.city = c3.address.city

Yet at runtime it gives the following error: Fatal error: Unexpectedly found nil while unwrapping an Optional value

Can you tell me which object is nil?

You can't!

The full code would be:

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        var c1 = NormalContact()
        let c3 = BadContact()

        c1.address.city = c3.address.city // compiler hides the truth from you and then you sudden get a crash
    }
}

struct NormalContact {
    var address : Address = Address(city: "defaultCity")
}

struct BadContact {
    var address : Address!
}

struct Address {
    var city : String
}

Long story short by using var address : Address! you're hiding the possibility that a variable can be nil from other readers. And when it crashes you're like "what the hell?! my address isn't an optional, so why am I crashing?!.

Hence it's better to write as such:

c1.address.city = c2.address!.city  // ERROR:  Fatal error: Unexpectedly found nil while unwrapping an Optional value 

Can you now tell me which object it is that was nil?

This time the code has been made more clear to you. You can rationalize and think that likely it's the address parameter that was forcefully unwrapped.

The full code would be :

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        var c1 = NormalContact()
        let c2 = GoodContact()

        c1.address.city = c2.address!.city
        c1.address.city = c2.address?.city // not compile-able. No deceiving by the compiler
        c1.address.city = c2.address.city // not compile-able. No deceiving by the compiler
        if let city = c2.address?.city {  // safest approach. But that's not what I'm talking about here. 
            c1.address.city = city
        }

    }
}

struct NormalContact {
    var address : Address = Address(city: "defaultCity")
}

struct GoodContact {
    var address : Address?
}

struct Address {
    var city : String
}

The cause of this error for me was...

ng-if="{{myTrustSrc(chat.src)}}"

in my template

It causes the function myTrustSrc in my controller to be called in an endless loop. If I remove the ng-if from this line, then the problem is solved.

<iframe ng-if="chat.src" id='chat' name='chat' class='chat' ng-src="{{myTrustSrc(chat.src)}}"></iframe>

The function is only called a few times when ng-if isn't used. I still wonder why the function is called more than once with ng-src?

This is the function in the controller

$scope.myTrustSrc = function(src) {
    return $sce.trustAsResourceUrl(src);
}

I also meet this problem, and I found the solution as 2 step below: 1. In sites-enabled folder of apache2, you edit in Directory element by set "AllowOverride all" (should be "all" not "none") 2. In kohana project in www folder, rename "example.htaccess" to ".htaccess"

I did it on ubuntu. Hope that it will help you.

From the documentation,

bool array_walk ( array &$array , callback $funcname [, mixed $userdata ] ) <-return bool

array_walk takes an array and a function F and modifies it by replacing every element x with F(x).

array array_map ( callback $callback , array $arr1 [, array $... ] )<-return array

array_map does the exact same thing except that instead of modifying in-place it will return a new array with the transformed elements.

array array_filter ( array $input [, callback $callback ] )<-return array

array_filter with function F, instead of transforming the elements, will remove any elements for which F(x) is not true

You're half way there on your own. To implement a refresh, you'd just wrap what you already have in a function on the scope:

function PersonListCtrl($scope, $http) {
  $scope.loadData = function () {
     $http.get('/persons').success(function(data) {
       $scope.persons = data;
     });
  };

  //initial load
  $scope.loadData();
}

then in your markup

<div ng-controller="PersonListCtrl">
    <ul>
        <li ng-repeat="person in persons">
            Name: {{person.name}}, Age {{person.age}}
        </li>
    </ul>
   <button ng-click="loadData()">Refresh</button>
</div>

As far as "accessing your model", all you'd need to do is access that $scope.persons array in your controller:

for example (just puedo code) in your controller:

$scope.addPerson = function() {
     $scope.persons.push({ name: 'Test Monkey' });
};

Then you could use that in your view or whatever you'd want to do.

Starting with VB.NET 10, implicit line continuation is supported for a number of syntax elements (see Statements in Visual Basic: Continuing a Statement over Multiple Lines). The concatenation operator (&) is in the list of syntax elements, that support implicit line continuation. Interspersed comments are supported as well, so your second example could be rewritten as:

dim createArticle as string = 
    "Create table article " &
    "    (articleID int " &           ' Comment for articleID
    "    ,articleName varchar(50) " & ' Comment for articleName
    "    )"

Implicit line continuation also works for query operators, with a few restrictions:

Before and after query operators (Aggregate, Distinct, From, Group By, Group Join, Join, Let, Order By, Select, Skip, Skip While, Take, Take While, Where, In, Into, On, Ascending, and Descending). You cannot break a line between the keywords of query operators that are made up of multiple keywords (Order By, Group Join, Take While, and Skip While).

Again, interspersed comments are allowed, so your first example can be rewritten as:

dim results = from a in articles
              where a.articleID = 4  ' articleID - now perfectly legal
              select a.articleName

The difference is in the scope of the variable. The @version is available to all methods of the class instance.

The short answer, if you're in the controller and you need to make the variable available to the view then use @variable.

For a much longer answer try this: http://www.ruby-doc.org/docs/ProgrammingRuby/html/tut_classes.html

You can use this:

yylval.sval=strdup("VHDL + Volcal trance...");

Where yylval is char*. strdup from does the job.

Please be aware that some answers in this thread suggesting use $[] is WRONG.

db.collection.update(
   {"events.profile":10},
   {$set:{"events.$[].handled":0}},
   {multi:true}
)

The above code will update "handled" to 0 for all elements in "events" array, regardless of its "profile" value. The query {"events.profile":10} is only to filter the whole document, not the documents in the array. In this situation it is a must to use $[elem] with arrayFilters to specify the condition of array items so Neil Lunn's answer is correct.

#/bin/bash   
TESTSTR="abc,def,ghij"

for i in $(echo $TESTSTR | tr ',' '\n')
do
echo $i
done

I prefer to use tr instead of sed, becouse sed have problems with special chars like \r \n in some cases.

other solution is to set IFS to certain separator

If you use form.close() in your form and set the FormClosing Event of your form and either use form.close() in this Event ,you fall in unlimited loop and Argument out of range happened and the solution is that change the form.close() with form.dispose() in Event of FormClosing. I hope this little tip help you!!!

If you want to get client key from request header, u can try following:

from rest_framework.authentication import BaseAuthentication
from rest_framework import exceptions
from apps.authentication.models import CerebroAuth

class CerebroAuthentication(BaseAuthentication):
def authenticate(self, request):
    client_id = request.META.get('HTTP_AUTHORIZATION')
    if not client_id:
        raise exceptions.AuthenticationFailed('Client key not provided')
    client_id = client_id.split()
    if len(client_id) == 1 or len(client_id) > 2:
        msg = ('Invalid secrer key header. No credentials provided.')
        raise exceptions.AuthenticationFailed(msg)
    try:
        client = CerebroAuth.objects.get(client_id=client_id[1])
    except CerebroAuth.DoesNotExist:
        raise exceptions.AuthenticationFailed('No such client')
    return (client, None)

My case is the page is sending multiple requests with different parameters when it was open. So most are being "stalled". Following requests immediately sent gets "stalled". Avoiding unnecessary requests would be better (to be lazy...).

You could use toPrecision() and toFixed() methods of Number type. Check this link How can I format numbers as money in JavaScript?

Not sure if this is cheating or not:

window.say = function(a) { alert(a); };

var a = "say('hello')";

var p = /^([^(]*)\('([^']*)'\).*$/;                 // ["say('hello')","say","hello"]

var fn = window[p.exec(a)[1]];                      // get function reference by name

if( typeof(fn) === "function") 
    fn.apply(null, [p.exec(a)[2]]);                 // call it with params

This question already has great answers. I'm only adding my two cents because I landed here trying to find a solution to my own problem, which is very similar to the OP.

If you want to find the INDEX of the first item matching a criteria using generators, you can simply do:

next(index for index, value in enumerate(iterable) if condition)

Just an update to the answer of @rafa.pereira. Since ggplot2 is part of tidyverse, it makes sense to use the convenient tidyverse functions to get rid of NAs.

library(tidyverse)
airquality %>% 
        drop_na(Ozone) %>%
        ggplot(aes(x = Ozone))+
        geom_bar(stat="bin")

Note that you can also use drop_na() without columns specification; then all the rows with NAs in any column will be removed.

Suppose you have less data, I suggest to try 70%, 80% and 90% and test which is giving better result. In case of 90% there are chances that for 10% test you get poor accuracy.

The good news is a transaction in SQL Server can span multiple batches (each exec is treated as a separate batch.)

You can wrap your EXEC statements in a BEGIN TRANSACTION and COMMIT but you'll need to go a step further and rollback if any errors occur.

Ideally you'd want something like this:

BEGIN TRY
    BEGIN TRANSACTION 
        exec( @sqlHeader)
        exec(@sqlTotals)
        exec(@sqlLine)
    COMMIT
END TRY
BEGIN CATCH

    IF @@TRANCOUNT > 0
        ROLLBACK
END CATCH

The BEGIN TRANSACTION and COMMIT I believe you are already familiar with. The BEGIN TRY and BEGIN CATCH blocks are basically there to catch and handle any errors that occur. If any of your EXEC statements raise an error, the code execution will jump to the CATCH block.

Your existing SQL building code should be outside the transaction (above) as you always want to keep your transactions as short as possible.

From the man page, npm start:

runs a package's "start" script, if one was provided. If no version is specified, then it starts the "active" version.

Admittedly, that description is completely unhelpful, and that's all it says. At least it's more documented than socket.io.

Anyhow, what really happens is that npm looks in your package.json file, and if you have something like

"scripts": { "start": "coffee server.coffee" }

then it will do that. If npm can't find your start script, it defaults to:

node server.js

Use this :

$('.select').val([]).trigger('change');

for in loops over enumerable property names of an object.

for of (new in ES6) does use an object-specific iterator and loops over the values generated by that.

In your example, the array iterator does yield all the values in the array (ignoring non-index properties).

As mentioned above, res.locals is a good (recommended) way to do this. See here for a quick tutorial on how to do this in Express.

given the following examples

• SQL Instance Name: MSSQLSERVER
• Port: 1433
• Hostname: MyKitchenPC
• IPv4: 10.242.137.227
• DNS Suffix: dir.svc.mykitchencompany.com

here are your possible servernames:

• localhost\MSSQLSERVER
• localhost,1433\MSSQLSERVER
• MyKitchenPC,1433\MSSQLSERVER
• 10.242.137.227,1433\MSSQLSERVER
• MyKitchenPC.dir.svc.mykitchencompany.com,1433\MSSQLSERVER

=IF(CR<=10, "RED", if(CR<50, "YELLOW", if(CR<101, "GREEN")))

CR = ColRow (Cell) This is an example. In this example when value in Cell is less then or equal to 10 then RED word will appear on that cell. In the same manner other if conditions are true if first if is false.

Just follow the steps in this URl: CLICK HERE

In this specific case, you should remove the elements in descending order. First index 5, then 3, then 1. This will remove the elements from the list without undesirable side effects.

for (int j = i.length-1; j >= 0; j--) {
    list.remove(i[j]);
}

I don't think any of the current answers really do what you said you want. (Correction: I now see that @Gareth Latty / @Lattyware has incorporated my answer into his own as an "Edit" near the end.)

Anyway, here's my take:

Say these are the tab-separated values in your input file:

1   2   3   4   5
6   7   8   9   10
11  12  13  14  15
16  17  18  19  20

then this:

with open("tab-separated-values.txt") as inp:
    print( list(zip(*(line.strip().split('\t') for line in inp))) )

would produce the following:

[('1', '6', '11', '16'), 
 ('2', '7', '12', '17'), 
 ('3', '8', '13', '18'), 
 ('4', '9', '14', '19'), 
 ('5', '10', '15', '20')]

As you can see, it put the k-th element of each row into the k-th array.

When using angular.copy, instead of updating the reference, a new object is created and assigned to the destination(if a destination is provided). But there's more. There's this cool thing that happens after a deep copy.

Say you have a factory service which has methods which updates factory variables.

angular.module('test').factory('TestService', [function () {
    var o = {
        shallow: [0,1], // initial value(for demonstration)
        deep: [0,2] // initial value(for demonstration)
    }; 
    o.shallowCopy = function () {
        o.shallow = [1,2,3]
    }
    o.deepCopy = function () {
        angular.copy([4,5,6], o.deep);
    }
    return o;
}]);

and a controller which uses this service,

angular.module('test').controller('Ctrl', ['TestService', function (TestService) {
     var shallow = TestService.shallow;
     var deep = TestService.deep;

     console.log('****Printing initial values');
     console.log(shallow);
     console.log(deep);

     TestService.shallowCopy();
     TestService.deepCopy();

     console.log('****Printing values after service method execution');
     console.log(shallow);
     console.log(deep);

     console.log('****Printing service variables directly');
     console.log(TestService.shallow);
     console.log(TestService.deep);
}]);

When the above program is run the output will be as follows,

****Printing initial values
[0,1]
[0,2]

****Printing values after service method execution
[0,1]
[4,5,6]

****Printing service variables directly
[1,2,3]
[4,5,6]

Thus the cool thing about using angular copy is that, the references of the destination are reflected with the change of values, without having to re-assign the values manually, again.

I got stuck on this issue for a long time following all the different remedies without avail.

I noticed that when adding a forward slash [/] to the end of the URL containing the dots [.], it did not throw a 404 error and it actually worked.

I finally solved the issue using a URL rewriter like IIS URL Rewrite to watch for a particular pattern and append the training slash.

My URL looks like this: /Contact/~firstname.lastname so my pattern is simply: /Contact/~(.*[^/])$

I got this idea from Scott Forsyth, see link below: http://weblogs.asp.net/owscott/handing-mvc-paths-with-dots-in-the-path

Two problems:

1 - You never told Git to start tracking any file

You write that you ran

git init
git commit -m "first commit"

and that, at that stage, you got

nothing added to commit but untracked files present (use "git add" to track).

Git is telling you that you never told it to start tracking any files in the first place, and it has nothing to take a snapshot of. Therefore, Git creates no commit. Before attempting to commit, you should tell Git (for instance):

Hey Git, you see that README.md file idly sitting in my working directory, there? Could you put it under version control for me? I'd like it to go in my first commit/snapshot/revision...

For that you need to stage the files of interest, using

git add README.md

before running

git commit -m "some descriptive message"

2 - You haven't set up the remote repository

You then ran

git remote add origin https://github.com/VijayNew/NewExample.git

After that, your local repository should be able to communicate with the remote repository that resides at the specified URL (https://github.com/VijayNew/NewExample.git)... provided that remote repo actually exists! However, it seems that you never created that remote repo on GitHub in the first place: at the time of writing this answer, if I try to visit the correponding URL, I get

Before attempting to push to that remote repository, you need to make sure that the latter actually exists. So go to GitHub and create the remote repo in question. Then and only then will you be able to successfully push with

git push -u origin master

What worked for me was fs.promises.

Example One:

const fs = require("fs")

fs.promises
  .writeFile(__dirname + '/test.json', "data", { encoding: 'utf8' })
  .then(() => {
    // Do whatever you want to do.
    console.log('Done');
  });

Example Two. Using Async-Await:

const fs = require("fs")

async function writeToFile() {
  await fs.promises.writeFile(__dirname + '/test-22.json', "data", {
    encoding: 'utf8'
  });

  console.log("done")
}

writeToFile()

You need to use Dispatcher.BeginInvoke. I did not test it but you can check this link(this is the same link provided by Julio G) to have better understanding on how to update the UI controls from different thread. I have modified your ReadData() code

public void ReadData()
{
    int counter = 0;

    while (SerialData.IsOpen)
    {
        if (counter == 0)
        {
            //try
            //{
                InputSpeed = Convert.ToInt16(SerialData.ReadChar());
                CurrentSpeed = InputSpeed;
                if (CurrentSpeed > MaximumSpeed)
                {
                    MaximumSpeed = CurrentSpeed;
                }
    SpeedTextBox.Dispatcher.BeginInvoke(System.Windows.Threading.DispatcherPriority.Normal,
        new Action(delegate() { SpeedTextBox.Text = "Current Wheel Speed = " + Convert.ToString(CurrentSpeed) + "Km/h"; });//update GUI from this thread


                DistanceTravelled = DistanceTravelled + (Convert.ToInt16(CurrentSpeed) * Time);

    DistanceTravelledTextBox.Dispatcher.BeginInvoke(System.Windows.Threading.DispatcherPriority.Normal,
        new Action(delegate() {DistanceTravelledTextBox.Text = "Total Distance Travelled = " + Convert.ToString(DistanceTravelled) + "Km"; });//update GUI from this thread

            //}
            //catch (Exception) { }
        }
        if (counter == 1)
        {
            try
            {
                RiderInput = Convert.ToInt16(SerialData.ReadLine());
                if (RiderInput > maximumRiderInput)
                {
                    maximumRiderInput = RiderInput;
                }                       
    RiderInputTextBox.Dispatcher.BeginInvoke(System.Windows.Threading.DispatcherPriority.Normal, 
        new Action(delegate() { RiderInputTextBox.Text = "Current Rider Input Power =" + Convert.ToString(RiderInput) + "Watts"; });//update GUI from this thread
            }
            catch (Exception) { }
        }
        if (counter == 2)
        {
            try
            {
                MotorOutput = Convert.ToInt16(SerialData.ReadLine());
                if (MotorOutput > MaximumMotorOutput)
                {
                    MaximumMotorOutput = MotorOutput;
                }
    MotorOutputTextBox.Dispatcher.BeginInvoke(System.Windows.Threading.DispatcherPriority.Normal, 
        new Action(delegate() { MotorOutputTextBox.Text = "Current Motor Output = " + Convert.ToString(MotorOutput) + "Watts"; });//update GUI from this thread                        
            }
            catch (Exception) { }
        }
        counter++;
        if (counter == 3)
        {
            counter = 0;
        }
    }
}

As Dumb Guy points out, it's important to note whether the array starts at zero and is sequential. Since you can make assignments to and unset non-contiguous indices ${#array[@]} is not always the next item at the end of the array.

$ array=(a b c d e f g h)
$ array[42]="i"
$ unset array[2]
$ unset array[3]
$ declare -p array     # dump the array so we can see what it contains
declare -a array='([0]="a" [1]="b" [4]="e" [5]="f" [6]="g" [7]="h" [42]="i")'
$ echo ${#array[@]}
7
$ echo ${array[${#array[@]}]}
h

Here's how to get the last index:

$ end=(${!array[@]})   # put all the indices in an array
$ end=${end[@]: -1}    # get the last one
$ echo $end
42

That illustrates how to get the last element of an array. You'll often see this:

$ echo ${array[${#array[@]} - 1]}
g

As you can see, because we're dealing with a sparse array, this isn't the last element. This works on both sparse and contiguous arrays, though:

$ echo ${array[@]: -1}
i

I've tried the solutions in this thread and the ones here, but simply calling setExtendedState(getExtendedState()|Frame.MAXIMIZED_BOTH); right after calling setVisible(true); apparently does not work for my environment (Windows 10, JDK 1.8, my taskbar is on the right side of my screen). Doing it this way still leaves a tiny space on the left, right and bottom .

What did work for me however, is calling setExtendedState(... when the window is activated, like so:

public class SomeFrame extends JFrame {

    public SomeFrame() {
        // ...
        setVisible(true);
        setResizable(true);
        // if you are calling setSize() for fallback size, do that here
        addWindowListener (
            new WindowAdapter() {
                private boolean shown = false;
                @Override
                public void windowActivated(WindowEvent we) {
                    if(shown) return;
                    shown = true;
                    setExtendedState(getExtendedState()|JFrame.MAXIMIZED_BOTH);
                }
            }
        );
    }
}

Mostafa has already pointed out that such a method is trivial to write, and mkb gave you a hint to use the binary search from the sort package. But if you are going to do a lot of such contains checks, you might also consider using a map instead.

It's trivial to check if a specific map key exists by using the value, ok := yourmap[key] idiom. Since you aren't interested in the value, you might also create a map[string]struct{} for example. Using an empty struct{} here has the advantage that it doesn't require any additional space and Go's internal map type is optimized for that kind of values. Therefore, map[string] struct{} is a popular choice for sets in the Go world.

i'd just do a simple check to see if d[a] exists and if not initialize it...

var a = "1",
    b = "hello",
    c = { "100" : "some important data" },
    d = {};

    if (d[a] === undefined) {
        d[a] = {}
    };
    d[a]["greeting"] = b;
    d[a]["data"] = c;

    console.debug (d);

This is probably unpopular way. But here how I do it:

object1 = // object to copy

YourClass *object2 = [[YourClass alloc] init];
object2.property1 = object1.property1;
object2.property2 = object1.property2;
..
etc.

Quite simple and straight forward. :P

Using boost:

#include <boost/algorithm/hex.hpp>

std::string s("tralalalala");
std::string result;
boost::algorithm::hex(s.begin(), s.end(), std::back_inserter(result));

Conform to UITextFieldDelegate.

func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
    // figure out what the new string will be after the pending edit
    let updatedString = (textField.text as NSString?)?.replacingCharacters(in: range, with: string)

    // Do whatever you want here


    // Return true so that the change happens
    return true
}

You can use the following solution to solve your problem:

echo date('H:i');

Ok, POD means plain old data. That usually refers to structs without any methods because these types are then used to structure multiple data that belong together.

As for structs not having methods: I have seen more than once that a struct had methods, and I don't feel that this would be unnatural.

Like This:

<?= $form->field($model, 'hidden')->hiddenInput(['class' => 'form-control', 'maxlength' => true,])->label(false) ?>

try this function $('div.total-title').text('test');

I assume that you're running a Linux, and you're using gEdit to edit your files. In the /etc/nginx/sites-enabled, it may have left a temp file e.g. default~ (watch the ~).

Depending on your editor, the file could be named .save or something like it. Just run $ ls -lah to see which files are unintended to be there and remove them (Thanks @Tisch for this).

Delete this file, and it will solve your problem.

There's a jQuery selector for that:

// Get all form fields that are hidden
var hidden_fields = $( this ).find( 'input:hidden' );

// Filter those which have a specific type
hidden_fields.attr( 'text' );

Will give you all hidden input fields and filter by those with a specific type="".

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

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

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

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

I tried restart: always, it works at some containers(like php-fpm), but i faced the problem that some containers(like nginx) is still not restarting after reboot.

Solved the problem.

crontab -e

@reboot (sleep 30s ; cd directory_has_dockercomposeyml ; /usr/local/bin/docker-compose up -d )&

for Java NetBeans 7.1 and later, even in NetBeans 8.0 (That i´m currently using) and later, the shortcut is:

Alt+Shift+F

if you look into the KeyMap accessing from the menu: Tools -> Options -> Keymap, the "action" is Format defined with the Shortcut : Alt+Shift+F

perl -pe 's/\..*$//;s{^.*/}{}'

I found a "better" way:

In CoffeeScript:

try data = JSON.parse(jqxhr.responseText)
data ||= { message: 'Server error, please retry' }

In Javascript:

var data;

try {
  data = JSON.parse(jqxhr.responseText);
} catch (_error) {}

data || (data = {
  message: 'Server error, please retry'
});

To define an array of strings it is more comfortable to use $var = @('User1 ', 'User2 ').

$servername = hostname
$smtpserver = 'localhost'
$emailTo = @('username1 <[email protected]>', 'username2<[email protected]>')
$emailFrom = 'SomeServer <[email protected]>'
Send-MailMessage -To $emailTo -Subject 'Low available memory' -Body 'Warning' -SmtpServer $smtpserver -From $emailFrom

SELECT * FROM tableName WHERE columnName LIKE "%#%" OR columnName LIKE "%$%" OR (etc.)

You don't need to use jQuery for this!

The native JavaScript implementation is Date.now().

Date.now() and $.now() return the same value:

Date.now(); // 1421715573651
$.now();    // 1421715573651

new Date(Date.now())   // Mon Jan 19 2015 20:02:55 GMT-0500 (Eastern Standard Time)
new Date($.now());     // Mon Jan 19 2015 20:02:55 GMT-0500 (Eastern Standard Time)

..and if you want the time formatted in hh-mm-ss:

var now = new Date(Date.now());
var formatted = now.getHours() + ":" + now.getMinutes() + ":" + now.getSeconds();
// 20:10:58

Now, to your question:

how to compare two elements coming from xml as string

In Xpath 1.0 strings can be compared only for equality (or inequality), using the operator = and the function not() together with the operator =.

$str1 = $str2

evaluates to true() exactly when the string $str1 is equal to the string $str2.

not($str1 = $str2)

evaluates to true() exactly when the string $str1 is not equal to the string $str2.

There is also the != operator. It generally should be avoided because it has anomalous behavior whenever one of its operands is a node-set.

Now, the rules for comparing two element nodes are similar:

$el1 = $el2

evaluates to true() exactly when the string value of $el1 is equal to the string value of $el2.

not($el1 = $el2)

evaluates to true() exactly when the string value of $el1 is not equal to the string value of $el2.

However, if one of the operands of = is a node-set, then

 $ns = $str

evaluates to true() exactly when there is at least one node in the node-set $ns1, whose string value is equal to the string $str

$ns1 = $ns2

evaluates to true() exactly when there is at least one node in the node-set $ns1, whose string value is equal to the string value of some node from $ns2

Therefore, the expression:

OU_NAME='OU_ADDR1'

evaluates to true() only when there is at least one element child of the current node that is named OU_NAME and whose string value is the string 'OU_ADDR1'.

This is obviously not what you want!

Most probably you want:

OU_NAME=OU_ADDR1

This expression evaluates to true exactly there is at least one OU_NAME child of the current node and one OU_ADDR1 child of the current node with the same string value.

Finally, in XPath 2.0, strings can be compared also using the value comparison operators lt, le, eq, gt, ge and the inherited from XPath 1.0 general comparison operator =.

Trying to evaluate a value comparison operator when one or both of its arguments is a sequence of more than one item results in error.

Assuming line of best fit for a set of points is:

y = a + b * x

b = ( sum(xi * yi) - n * xbar * ybar ) / sum((xi - xbar)^2)
a = ybar - b * xbar

Code and plot

# sample points 
X = [0, 5, 10, 15, 20]
Y = [0, 7, 10, 13, 20]

# solve for a and b
def best_fit(X, Y):

    xbar = sum(X)/len(X)
    ybar = sum(Y)/len(Y)
    n = len(X) # or len(Y)

    numer = sum([xi*yi for xi,yi in zip(X, Y)]) - n * xbar * ybar
    denum = sum([xi**2 for xi in X]) - n * xbar**2

    b = numer / denum
    a = ybar - b * xbar

    print('best fit line:\ny = {:.2f} + {:.2f}x'.format(a, b))

    return a, b

# solution
a, b = best_fit(X, Y)
#best fit line:
#y = 0.80 + 0.92x

# plot points and fit line
import matplotlib.pyplot as plt
plt.scatter(X, Y)
yfit = [a + b * xi for xi in X]
plt.plot(X, yfit)

UPDATE:

notebook version

I was looking for a simple answer to solve this myself. here is what I found

This will split the year and month, take one month off and get the first day.

firstDayInPreviousMonth = DateSerial(Year(dtmDate), Month(dtmDate) - 1, 1)

Gets the first day of the previous month from the current

lastDayInPreviousMonth = DateSerial(Year(dtmDate), Month(dtmDate), 0)

More details can be found at: http://msdn.microsoft.com/en-us/library/aa227522%28v=vs.60%29.aspx

Try the following:

List<Map<String, ArrayList<String>>> mapList = 
    new ArrayList<Map<String, ArrayList<String>>>();
mapList.add(map);

If your list must be of type List<HashMap<String, ArrayList<String>>>, then declare your map variable as a HashMap and not a Map.

ponder Try Heap. I believe it's the most consistent of the O(n lg n) sorts.

Update PHP 7.4

Curly brace access syntax is deprecated since PHP 7.4

Update 2019

Moving on to the best practices of OOPS, @MrTrick's answer must be marked as correct, although my answer provides a hacked solution its not the best method.

Simply iterate its using {}

Example:

$videos{0}->id

This way your object is not destroyed and you can easily iterate through object.

For PHP 5.6 and below use this

$videos{0}['id']

Both array() and the stdClass objects can be accessed using the current() key() next() prev() reset() end() functions.

So, if your object looks like

object(stdClass)#19 (3) {
  [0]=>
  object(stdClass)#20 (22) {
    ["id"]=>
    string(1) "123"
  etc...

Then you can just do;

$id = reset($obj)->id; //Gets the 'id' attr of the first entry in the object

If you need the key for some reason, you can do;

reset($obj); //Ensure that we're at the first element
$key = key($obj);

Hope that works for you. :-) No errors, even in super-strict mode, on PHP 5.4

2022 Update:
After PHP 7.4, using current(), end(), etc functions on objects is deprecated.

In newer versions of PHP, use the ArrayIterator class:

$objIterator = new ArrayIterator($obj);

$id = $objIterator->current()->id; // Gets the 'id' attr of the first entry in the object

$key = $objIterator->key(); // and gets the key

The second parameter of findBy is for ORDER.

$ens = $em->getRepository('AcmeBinBundle:Marks')
          ->findBy(
             array('type'=> 'C12'), 
             array('id' => 'ASC')
           );

Can we see your import block? because it seems that you have imported the wrong Iterator class.

The one you should use is java.util.Iterator

To make sure, try:

java.util.Iterator iter = hm.keySet().iterator();

I personally suggest the following:

Map Declaration using Generics and declaration using the Interface Map<K,V> and instance creation using the desired implementation HashMap<K,V>

Map<Integer, String> hm = new HashMap<>();

and for the loop:

for (Integer key : hm.keySet()) {
    System.out.println("Key = " + key + " - " + hm.get(key));
}

UPDATE 3/5/2015

Found out that iterating over the Entry set will be better performance wise:

for (Map.Entry<Integer, String> entry : hm.entrySet()) {
    Integer key = entry.getKey();
    String value = entry.getValue();

}

UPDATE 10/3/2017

For Java8 and streams, your solution will be (Thanks @Shihe Zhang)

 hm.forEach((key, value) -> System.out.println(key + ": " + value))

If you have Symbol properties in your object, that should be filtered too, you can not use: Object.keys Object.entries Object.fromEntries, ... because:

Symbol keys are not enumerable !

You could use Reflect.ownKeys and filter keys in reduce

Reflect.ownKeys(o).reduce((a, k) => allow.includes(k) && {...a, [k]: o[k]} || a, {});

(Open DevTools for log output - Symbols are not logged on Stackoverflow UI)

const bKey = Symbol('b_k');
const o = {
    a:                 1,
    [bKey]:            'b',
    c:                 [1, 3],
    [Symbol.for('d')]: 'd'
};

const allow = ['a', bKey, Symbol.for('d')];

const z1 = Reflect.ownKeys(o).reduce((a, k) => allow.includes(k) && {...a, [k]: o[k]} || a, {});

console.log(z1);                   // {a: 1, Symbol(b_k): "b", Symbol(d): "d"}
console.log(bKey in z1)            // true
console.log(Symbol.for('d') in z1) // true

This is equal to this

const z2 = Reflect.ownKeys(o).reduce((a, k) => allow.includes(k) && Object.assign(a, {[k]: o[k]}) || a, {});
const z3 = Reflect.ownKeys(o).reduce((a, k) => allow.includes(k) && Object.defineProperty(a, k, {value: o[k]}) || a, {});

console.log(z2); // {a: 1, Symbol(b_k): "b", Symbol(d): "d"}
console.log(z3); // {a: 1, Symbol(b_k): "b", Symbol(d): "d"}

Wrapped in a filter() function, an optional target object could be passed

const filter = (o, allow, t = {}) => Reflect.ownKeys(o).reduce(
    (a, k) => allow.includes(k) && {...a, [k]: o[k]} || a, 
    t
);

console.log(filter(o, allow));           // {a: 1, Symbol(b_k): "b", Symbol(d): "d"}
console.log(filter(o, allow, {e: 'e'})); // {a: 1, e: "e", Symbol(b_k): "b", Symbol(d): "d"}

I can show you with an example:

function fullName(first, last) {_x000D_
  let fullName = first + " " + last;_x000D_
  return fullName;_x000D_
}_x000D_
_x000D_
function fullNameStringInterpolation(first, last) {_x000D_
  let fullName = `${first} ${last}`;_x000D_
  return fullName;_x000D_
}_x000D_
_x000D_
console.log('Old School: ' + fullName('Carlos', 'Gutierrez'));_x000D_
_x000D_
console.log('New School: ' + fullNameStringInterpolation('Carlos', 'Gutierrez'));

If you're set on using scanf, you can do something like the following:

int val;
char follow;  
int read = scanf( "%d%c", &val, &follow );

if ( read == 2 )
{
  if ( isspace( follow ) )
  {
    // input is an integer followed by whitespace, accept
  }
  else
  {
    // input is an integer followed by non-whitespace, reject
  }
}
else if ( read == 1 )
{
  // input is an integer followed by EOF, accept
}
else
{
  // input is not an integer, reject
}

Try this

<html>
    <head>
        <script type="text/javascript">
        function runProgram()
        {
            var shell = new ActiveXObject("WScript.Shell");                 
            var appWinMerge = "\"C:\\Program Files\\WinMerge\\WinMergeU.exe\" /e /s /u /wl /wr /maximize";
            var fileLeft = "\"D:\\Path\\to\\your\\file\"";
            var fileRight= "\"D:\\Path\\to\\your\\file2\"";
            shell.Run(appWinMerge + " " + fileLeft + " " + fileRight);
        }
        </script>
    </head>

    <body>
        <a href="javascript:runProgram()">Run program</a>
    </body>
</html>

To figure out if an Integer is greater than 0, you can:

• check if compareTo(O) returns a positive number:

  if (count.compareTo(0) > 0)
       ...
  

  But that looks pretty silly, doesn't it? Better just...

• use autoboxing¹:

  if (count > 0)
      ....
  

  This is equivalent to:

  if (count.intValue() > 0)
      ...
  

  It is important to note that "==" is evaluated like this, with the Integer operand unboxed rather than the int operand boxed. Otherwise, count == 0 would return false when count was initialized as new Integer(0) (because "==" tests for reference equality).

¹Technically, the first example uses autoboxing (before Java 1.5 you couldn't pass an int to compareTo) and the second example uses unboxing. The combined feature is often simply called "autoboxing" for short, which is often then extended into calling both types of conversions "autoboxing". I apologize for my lax usage of terminology.

UIView.transition(with: title3Label, duration: 0.4,
                          options: .transitionCrossDissolve,
                          animations: {
                            self.title3Label.isHidden = !self.title3Label.isHidden
                      })

Applying transition on View with some delay gives hide and show effect

For anyone looking to style child elements of a :host here is an example of how to use ::ng-deep

:host::ng-deep <child element>

e.g :host::ng-deep span { color: red; }

As others said /deep/ is deprecated

Also add the key "StartingMonthColumn" in App.config that you run application from, for example in the App.config of the test project.

Both the accepted answer and even the FDPI homepage seem to give botched or incomplete examples. Here's mine which works and is easy to implement. As expected it requires fpdf and fpdi libraries:

• FPDF: http://www.fpdf.org/en/download.php
• FPDI: https://www.setasign.com/products/fpdi/downloads

require('fpdf.php');
require('fpdi.php');

$files = ['doc1.pdf', 'doc2.pdf', 'doc3.pdf'];

$pdf = new FPDI();

// iterate over array of files and merge
foreach ($files as $file) {
    $pageCount = $pdf->setSourceFile($file);
    for ($i = 0; $i < $pageCount; $i++) {
        $tpl = $pdf->importPage($i + 1, '/MediaBox');
        $pdf->addPage();
        $pdf->useTemplate($tpl);
    }
}

// output the pdf as a file (http://www.fpdf.org/en/doc/output.htm)
$pdf->Output('F','merged.pdf');

The way you declare the date property as an input looks incorrect but its hard to say if it's the only problem without seeing all your code. Rather than using @Input('date') declare the date property like so: private _date: string;. Also, make sure you are instantiating the model with the new keyword. Lastly, access the property using regular dot notation.

Check your work against this example from https://www.typescriptlang.org/docs/handbook/classes.html :

let passcode = "secret passcode";

class Employee {
    private _fullName: string;

    get fullName(): string {
        return this._fullName;
    }

    set fullName(newName: string) {
        if (passcode && passcode == "secret passcode") {
            this._fullName = newName;
        }
        else {
            console.log("Error: Unauthorized update of employee!");
        }
    }
}

let employee = new Employee();
employee.fullName = "Bob Smith";
if (employee.fullName) {
    console.log(employee.fullName);
}

In my case for exact same error, I was also not the only developer.

So I went to commit & push my changes at same time, seen at bottom of the Commit dialog popup:

...but I made the huge mistake of forgetting to hit the Fetch button to see if I have latest, which I did not.

The commit successfully executed, however not the push, but instead gives the same mentioned error; ...even though other developers didn't alter same files as me, I cannot pull latest as same error is presented.

The GUI Solution

Most of the time I prefer sticking with Sourcetree's GUI (Graphical User Interface). This solution might not be ideal, however this is what got things going again for me without worrying that I may lose my changes or compromise more recent updates from other developers.

STEP 1

Right-click on the commit right before yours to undo your locally committed changes and select Reset current branch to this commit like so:

STEP 2

Once all the loading spinners disappear and Sourcetree is done loading the previous commit, at the top-left of window, click on Pull button...

...then a dialog popup will appear, and click the OK button at bottom-right:

STEP 3

After pulling latest, if you do not get any errors, skip to STEP 4 (next step below). Otherwise if you discover any merge conflicts at this point, like I did with my Web.config file:

...then click on the Stash button at the top, a dialog popup will appear and you will need to write a Descriptive-name-of-your-changes, then click the OK button:

...once Sourcetree is done stashing your altered file(s), repeat actions in STEP 2 (previous step above), and then your local files will have latest changes. Now your changes can be reapplied by opening your STASHES seen at bottom of Sourcetree left column, use the arrow to expand your stashes, then right-click to choose Apply Stash 'Descriptive-name-of-your-changes', and after select OK button in dialog popup that appears:

IF you have any Merge Conflict(s) right now, go to your preferred text-editor, like Visual Studio Code, and in the affected files select the Accept Incoming Change link, then save:

Then back to Sourcetree, click on the Commit button at top:

then right-click on the conflicted file(s), and under Resolve Conflicts select the Mark Resolved option:

STEP 4

Finally!!! We are now able to commit our file(s), also checkmark the Push changes immediately to origin option before clicking the Commit button:

P.S. while writing this, a commit was submitted by another developer right before I got to commit, so had to pretty much repeat steps.

This is what I found. Adding /usr/local/apache-tomcat-7.0.64/lib/servlet-api.jar in my environment variable as CLASSPATH. OS is iOS.

if using bash: ~/.bash_profile $CLASSPATH=/usr/local/apache-tomcat-7.0.64/lib/servlet-api.jar

if using zsh: ~/.zshrc export CLASSPATH="usr/local/apache-tomcat-7.0.64/lib/servlet-api.jar"

Force it work right now, run source .bash_profile (or .zshrc) or one can restart computer and it works for the current user.

You can try this one

img{
    max-height:500px;
    max-width:500px;
    height:auto;
    width:auto;
}

This keeps the aspect ratio of the image and prevents either the two dimensions exceed 500px

You can check this post

you can just use this code to hit the script using cron job using cpanel:

Google had changed their policy so the old way for getting the Google profile image will not work now, which was

https://plus.google.com/s2/photos/profile/(user_id)?sz=150

New Way for doing this is

Request URL

https://www.googleapis.com/plus/v1/people/115950284...320?fields=image&key={YOUR_API_KEY}

That will give the Google profile image url in json format as given below

Response :

{
    "image": 
    {
         "url": "https://lh3.googleusercontent.com/-OkM...AANA/ltpH4BFZ2as/photo.jpg?sz=50"
    }
}

More parameters can be found to send with URL which you may need from here

The easiest way to do it is to add mb-5 to your classes. That is <div class='row mb-5'>.

NOTE:

• mb varies betweeen 1 to 5
• The Div MUST have the row class

Short answer:

64 bits platforms only!

function milliseconds() {
    $mt = explode(' ', microtime());
    return ((int)$mt[1]) * 1000 + ((int)round($mt[0] * 1000));
}

[ If you are running 64 bits PHP then the constant PHP_INT_SIZE equals to 8 ]

Long answer:

If you want an equilvalent function of time() in milliseconds first you have to consider that as time() returns the number of seconds elapsed since the "epoch time" (01/01/1970), the number of milliseconds since the "epoch time" is a big number and doesn't fit into a 32 bits integer.

The size of an integer in PHP can be 32 or 64 bits depending on platform.

From http://php.net/manual/en/language.types.integer.php

The size of an integer is platform-dependent, although a maximum value of about two billion is the usual value (that's 32 bits signed). 64-bit platforms usually have a maximum value of about 9E18, except for Windows, which is always 32 bit. PHP does not support unsigned integers. Integer size can be determined using the constant PHP_INT_SIZE, and maximum value using the constant PHP_INT_MAX since PHP 4.4.0 and PHP 5.0.5.

If you have 64 bits integers then you may use the following function:

function milliseconds() {
    $mt = explode(' ', microtime());
    return ((int)$mt[1]) * 1000 + ((int)round($mt[0] * 1000));
}

microtime() returns the number of seconds since the "epoch time" with precision up to microseconds with two numbers separated by space, like...

0.90441300 1409263371

The second number is the seconds (integer) while the first one is the decimal part.

The above function milliseconds() takes the integer part multiplied by 1000

1409263371000

then adds the decimal part multiplied by 1000 and rounded to 0 decimals

1409263371904

Note that both $mt[1] and the result of round are casted to int. This is necessary because they are floats and the operation on them without casting would result in the function returning a float.

Finally, that function is slightly more precise than

round(microtime(true)*1000);

that with a ratio of 1:10 (approx.) returns 1 more millisecond than the correct result. This is due to the limited precision of the float type (microtime(true) returns a float). Anyway if you still prefer the shorter round(microtime(true)*1000); I would suggest casting to int the result.

Even if it's beyond the scope of the question it's worth mentioning that if your platform supports 64 bits integers then you can also get the current time in microseconds without incurring in overflow.

If fact 2^63 - 1 (biggest signed integer) divided by 10^6 * 3600 * 24 * 365 (approximately the microseconds in one year) gives 292471.

That's the same value you get with

echo (int)( PHP_INT_MAX / ( 1000000 * 3600 * 24 * 365 ) );

In other words, a signed 64 bits integer have room to store a timespan of over 200,000 years measured in microseconds.

You may have then

function microseconds() {
    $mt = explode(' ', microtime());
    return ((int)$mt[1]) * 1000000 + ((int)round($mt[0] * 1000000));
}

In the latest S3 Management Console, when you click on the CORS configuration on the Permissions tab, it will show a default sample CORS configuration. This configuration is not actually active, however! You have to first click save in order to activate CORS.

It took me way too long to figure this out, hopefully this will save someone some time.
