Peter, you should really take a look at Canappi, it does all that for you, all you have to do is specify the layout as such:

button mySubmitButton 'Sumbit' (100,100,100,30 + 0,88,0,0) { ... }

From there Canappi will generate the correct objective-c code that detects the device the app is running on and will use:

(100,100,100,30) for iPhone4
(100,**188**,100,30) for iPhone 5

Canappi works like Interface Builder and Story Board combined, except that it is in a textual form. If you already have XIB files, you can convert them so you don't have to recreate the entire UI from scratch.

As non-root user ideally:

scp -r src $host:$path

If you already some of the content on $host consider using rsync with ssh as a tunnel.

Here are some more console logging "pro tips":

console.table

var animals = [
    { animal: 'Horse', name: 'Henry', age: 43 },
    { animal: 'Dog', name: 'Fred', age: 13 },
    { animal: 'Cat', name: 'Frodo', age: 18 }
];

console.table(animals);

console.trace

Shows you the call stack for leading up to the console.

You can even customise your consoles to make them stand out

console.todo = function(msg) {
    console.log(‘ % c % s % s % s‘, ‘color: yellow; background - color: black;’, ‘–‘, msg, ‘–‘);
}

console.important = function(msg) {
    console.log(‘ % c % s % s % s’, ‘color: brown; font - weight: bold; text - decoration: underline;’, ‘–‘, msg, ‘–‘);
}

console.todo(“This is something that’ s need to be fixed”);
console.important(‘This is an important message’);

If you really want to level up don't limit your self to the console statement.

Here is a great post on how you can integrate a chrome debugger right into your code editor!

OK, using uuid package, it support for version 1, 3, 4 and 5 UUIDs do:

yarn add uuid

and then:

const uuidv1 = require('uuid/v1');
uuidv1(); // ? '45745c60-7b1a-11e8-9c9c-2d42b21b1a3e'

You can also do it with fully-specified options:

const v1options = {
  node: [0x01, 0x23, 0x45, 0x67, 0x89, 0xab],
  clockseq: 0x1234,
  msecs: new Date('2011-11-01').getTime(),
  nsecs: 5678
};
uuidv1(v1options); // ? '710b962e-041c-11e1-9234-0123456789ab'

Recently i found the AribaWeb Framework which looks very promising. It offers good functionality (even AJAX), good documentation. written in Groovy/Java and even includes a Tomcat-Server. Trying to get into Spring really made me mad.

As of Spring 3.0, Spring offers support for JSR-330 dependency injection annotations (@Inject, @Named, @Singleton).

There is a separate section in the Spring documentation about them, including comparisons to their Spring equivalents.

Just use -p1: you will need to use -p0 in the --no-prefix case anyway, so you can just leave out the --no-prefix and use -p1:

$ git diff > save.patch
$ patch -p1 < save.patch

$ git diff --no-prefix > save.patch
$ patch -p0 < save.patch

Just to be clear, you need to go to the controlpanel\System\Advanced system settings\Environment Variables\Path, then hit edit and add:

C:Users\user.user\Anaconda3\Scripts

to the end and restart the cmd line

The accepted solution is probably the best bet for your purposes, but to actually answer the question in the subject line:

In my app, I have to get the path from URIs and get the URI from paths. The former:

/**
 * Gets the corresponding path to a file from the given content:// URI
 * @param selectedVideoUri The content:// URI to find the file path from
 * @param contentResolver The content resolver to use to perform the query.
 * @return the file path as a string
 */
private String getFilePathFromContentUri(Uri selectedVideoUri,
        ContentResolver contentResolver) {
    String filePath;
    String[] filePathColumn = {MediaColumns.DATA};

    Cursor cursor = contentResolver.query(selectedVideoUri, filePathColumn, null, null, null);
    cursor.moveToFirst();

    int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
    filePath = cursor.getString(columnIndex);
    cursor.close();
    return filePath;
}

The latter (which I do for videos, but can also be used for Audio or Files or other types of stored content by substituting MediaStore.Audio (etc) for MediaStore.Video):

/**
 * Gets the MediaStore video ID of a given file on external storage
 * @param filePath The path (on external storage) of the file to resolve the ID of
 * @param contentResolver The content resolver to use to perform the query.
 * @return the video ID as a long
 */
private long getVideoIdFromFilePath(String filePath,
        ContentResolver contentResolver) {


    long videoId;
    Log.d(TAG,"Loading file " + filePath);

            // This returns us content://media/external/videos/media (or something like that)
            // I pass in "external" because that's the MediaStore's name for the external
            // storage on my device (the other possibility is "internal")
    Uri videosUri = MediaStore.Video.Media.getContentUri("external");

    Log.d(TAG,"videosUri = " + videosUri.toString());

    String[] projection = {MediaStore.Video.VideoColumns._ID};

    // TODO This will break if we have no matching item in the MediaStore.
    Cursor cursor = contentResolver.query(videosUri, projection, MediaStore.Video.VideoColumns.DATA + " LIKE ?", new String[] { filePath }, null);
    cursor.moveToFirst();

    int columnIndex = cursor.getColumnIndex(projection[0]);
    videoId = cursor.getLong(columnIndex);

    Log.d(TAG,"Video ID is " + videoId);
    cursor.close();
    return videoId;
}

Basically, the DATA column of MediaStore (or whichever sub-section of it you're querying) stores the file path, so you use that info to look it up.

The problem is that System. currentTimeMillis(); returns the number of milliseconds from 1970-01-01T00:00:00Z, but new Date() gives the current local time. Adding the ZONE_OFFSET and DST_OFFSET from the Calendar class gives you the time in UTC.

Calendar rightNow = Calendar.getInstance();

// offset to add since we're not UTC

long offset = rightNow.get(Calendar.ZONE_OFFSET) +
    rightNow.get(Calendar.DST_OFFSET);

long sinceMidnight = (rightNow.getTimeInMillis() + offset) %
    (24 * 60 * 60 * 1000);

System.out.println(sinceMidnight + " milliseconds since midnight");

You cannot open Java Applets (nor any other NPAPI plugin) in Microsoft Edge - they aren't supported and won't be added in the future.

Further you should be aware that in the next release of Google Chrome (v45 - due September 2015) NPAPI plugins will also no longer be supported.

Work-arounds

There are a couple of things that you can do:

Use Internet Explorer 11
You will find that in Windows 10 you will already have Internet Explorer 11 installed. IE 11 continues to support NPAPI (incl Java Applets). IE11 is squirrelled away (c:\program files\internet explorer\iexplore.exe). Just pin this exe to your task bar for easy access.

Use FireFox
You can also install and use a Firefox 32-bit Extended Support Release in Win10. Firefox have disabled NPAPI by default, but this can be overridden. This will only be supported until early 2018.

This thread is perhaps very very old now. But want to share these results for someone who see this thread. Ran a comparison betn. Flotr2, ChartJS, highcharts asynchronously. Flotr2 seems to be the quickest. Tested this by passing a new data point every 50ms upto 1000 data points totally. Flotr2 was the quickest for me though it appears to be redrawing charts regularly.

Go to get AbacusUtil. Thread number can by specified for parallel stream. Here is the sample code:

LongStream.range(4, 1_000_000).parallel(threadNum)...

Disclosure: I'm the developer of AbacusUtil.

This function should work. this has the photo parameter that holds the base64 string and also path to an existing image directory should you already have an existing image you want to unlink while you save the new one.

 public function convertBase64ToImage($photo = null, $path = null) {
    if (!empty($photo)) {
        $photo = str_replace('data:image/png;base64,', '', $photo);
        $photo = str_replace(' ', '+', $photo);
        $photo = str_replace('data:image/jpeg;base64,', '', $photo);
        $photo = str_replace('data:image/gif;base64,', '', $photo);
        $entry = base64_decode($photo);
        $image = imagecreatefromstring($entry);

        $fileName = time() . ".jpeg";
        $directory = "uploads/customer/" . $fileName;

        header('Content-type:image/jpeg');

        if (!empty($path)) {
            if (file_exists($path)) {
                unlink($path);
            }
        }

        $saveImage = imagejpeg($image, $directory);

        imagedestroy($image);

        if ($saveImage) {
            return $fileName;
        } else {
            return false; // image not saved
        }
    }
}

[Edit] After reviewing the Mongoose documentation, it looks like you can send each query result as a separate chunk; the web server uses chunked transfer encoding by default so all you have to do is wrap an array around the items to make it a valid JSON object.

Roughly (untested):

app.get('/users/:email/messages/unread', function(req, res, next) {
  var firstItem=true, query=MessageInfo.find(/*...*/);
  res.writeHead(200, {'Content-Type': 'application/json'});
  query.each(function(docs) {
    // Start the JSON array or separate the next element.
    res.write(firstItem ? (firstItem=false,'[') : ',');
    res.write(JSON.stringify({ msgId: msg.fileName }));
  });
  res.end(']'); // End the JSON array and response.
});

Alternatively, as you mention, you can simply send the array contents as-is. In this case the response body will be buffered and sent immediately, which may consume a large amount of additional memory (above what is required to store the results themselves) for large result sets. For example:

// ...
var query = MessageInfo.find(/*...*/);
res.writeHead(200, {'Content-Type': 'application/json'});
res.end(JSON.stringify(query.map(function(x){ return x.fileName })));

I tried all of the above solutions none work for me, I found the solution here

• Open ActivityLog.xml by going into

  C:\Users\{UserName}\AppData\Roaming\Microsoft\VisualStudio\15.{Id} 
  

• Check if error states that

  "CreateInstance failed for package 
  [ReferenceManagerPackage]Source: 'mscorlib' Description: Could not load type 
   'Microsoft.VisualStudio.Shell.Interop.' from assembly 
   'Microsoft.VisualStudio.Shell.Interop.11.0' 
  

• Then run this gacutil command through VS Cmd prompt (admin mode):

  1. Navigate to

     C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\PublicAssemblies   
     

  2. Run gacutil -i Microsoft.VisualStudio.Shell.Interop.11.0.dll

I would suggest that you use Apache's commons logging utility. It is highly scalable and supports separate log files for different loggers. See here.

Since I had troubles understanding this post here is a simple explanation for people like me. It is useful if:

• You DO NOT need Load Balacing.
• You DO NOT want to use nginx to do port forwarding.
• You DO want to do PORT FORWARDING according to specific subdomains using SRV record.

Then here is what you need to do:

SRV records:

_minecraft._tcp.1.12          IN SRV    1 100 25567 1.12.<your-domain-name.com>.
_minecraft._tcp.1.13          IN SRV    1 100 25566 1.13.<your-domain-name.com>.

(I did not need a srv record for 1.14 since my 1.14 minecraft server was already on the 25565 port which is the default port of minecraft.)

And the A records:

1.12                          IN A      <your server IP>
1.13                          IN A      <your server IP>
1.14                          IN A      <your server IP>

The PAM module to limit resources caused exactly the results you described: My process died mysteriously with the text Killed on the console window. No log output, neither in syslog nor in kern.log. The top program helped me to discover that exactly after one minute of CPU usage my process gets killed.

Here are some more tests

True if string is not empty:

[ -n "$var" ]
[[ -n $var ]]
test -n "$var"
[ "$var" ]
[[ $var ]]
(( ${#var} ))
let ${#var}
test "$var"

True if string is empty:

[ -z "$var" ]
[[ -z $var ]]
test -z "$var"
! [ "$var" ]
! [[ $var ]]
! (( ${#var} ))
! let ${#var}
! test "$var"

i was facing the same issue with misspelled enctype="multipart/form-data", i was fix this exception by doing correct spelling . Current request is not a multipart request client side error so please check your form.

When you set 64-bit the resulting binary is a "Fat" binary, which contains all three Mach-O images bundled with a thin fat header. You can see that using otool or jtool. You can check out some fat binaries included as part of the iOS 7.0 SDK, for example the AVFoundation Framework, like so:

% cd  /Developer/Platforms/iPhoneOS.platform/DeviceSupport/7.0\ \(11A465\)/Symbols/System/Library/Frameworks/AVFoundation.framework/

%otool -V -f AVFoundation                                                                     9:36

    align 2^14 (16384)

As for the binary itself, it uses the ARM64 bit instruction set, which is (mostly compatible with 32-bit, but) a totally different instruction set. This is especially important for graphics program (using NEON instructions and registers). Likewise, the CPU has more registers, which makes quite an impact on program speed. There's an interesting discussion in http://blogs.barrons.com/techtraderdaily/2013/09/19/apple-the-64-bit-question/?mod=yahoobarrons on whether or not this makes a difference; benchmarking tests have so far clearly indicated that it does.

Using otool -tV will dump the assembly (if you have XCode 5 and later), and then you can see the instruction set differences for yourself. Most (but not all) developers will remain agnostic to the changes, as for the most part they do not directly affect Obj-C (CG* APIs notwithstanding), and have to do more with low level pointer handling. The compiler will work its magic and optimizations.

Sounds a bit familiar with my problem: aapt not found under the right path

I needed to clean all open projects to get it working again...

Try this:

$("#upload_link,#upload_link2,#upload_link3").each(function(){
    $(this).upload({
        //whateveryouwant
    });
});

For some reason I need to use protobuf 2.4.1 in my project on OS X El Capitan. However homebrew has removed protobuf241 from its formula. I install it according @kksensei's answer manually and have to fix some error during the process.

During the make process, I get 3 error like following:

(Sorry, I dont know how to attach code when the code contains '`' )

If you get the same error, please edit src/google/protobuf/message.cc, add #include <istream> at the top of the file and do $ make again and should get no errors. After that do $ sudo make install. When install finished $protoc --version should display the correct result.

use built in php function is_numeric to check if the value is numeric.

I'm not sure that you're creating a set with this ([1, 2]) syntax, rather a list. To create a set, you should use set([1, 2]).

These brackets are just envelopping your expression, as if you would have written:

if (condition1
    and condition2 == 3):
    print something

There're not really ignored, but do nothing to your expression.

Note: (something, something_else) will create a tuple (but still no list).

toISOString() will return current UTC time only not the current local time. If you want to get the current local time in yyyy-MM-ddTHH:mm:ss.SSSZ format then you should get the current time using following two methods

Method 1:

document.write(new Date(new Date().toString().split('GMT')[0]+' UTC').toISOString());

Method 2:

document.write(new Date(new Date().getTime() - new Date().getTimezoneOffset() * 60000).toISOString());

The suggested by Soonil way of keeping a state for the application is good, however it has one weak point - there are cases when OS kills the entire application process. Here is the documentation on this - Processes and lifecycles.

Consider a case - your app goes into the background because somebody is calling you (Phone app is in the foreground now). In this case && under some other conditions (check the above link for what they could be) the OS may kill your application process, including the Application subclass instance. As a result the state is lost. When you later return to the application, then the OS will restore its activity stack and Application subclass instance, however the myState field will be null.

AFAIK, the only way to guarantee state safety is to use any sort of persisting the state, e.g. using a private for the application file or SharedPrefernces (it eventually uses a private for the application file in the internal filesystem).

With EF or LINQ to SQL:

var item = db.Items.OrderByDescending(i => i.Value).FirstOrDefault();

With LINQ to Objects I suggest to use morelinq extension MaxBy (get morelinq from nuget):

var item = items.MaxBy(i => i.Value);

This solution is based on the one proposed by fei0x but it has the advantages that there is no need to join the value list of constants in the query and constants can be easily listed at the start of the query. It also works in recursive queries.

Basically, every constant is a single-value table declared in a WITH clause which can then be called anywhere in the remaining part of the query.

• Basic example with two constants:

WITH
    constant_1_str AS (VALUES ('Hello World')),
    constant_2_int AS (VALUES (100))
SELECT *
FROM some_table
WHERE table_column = (table constant_1_str)
LIMIT (table constant_2_int)

Alternatively you can use SELECT * FROM constant_name instead of TABLE constant_name which might not be valid for other query languages different to postgresql.

Plain JavaScript:

You don't need jQuery to do something trivial like this. Just use the .removeAttribute() method.

Assuming you are just targeting a single element, you can easily use the following: (example)

document.querySelector('#target').removeAttribute('style');

If you are targeting multiple elements, just loop through the selected collection of elements: (example)

var target = document.querySelectorAll('div');
Array.prototype.forEach.call(target, function(element){
    element.removeAttribute('style');
});

Array.prototype.forEach() - IE9 and above / .querySelectorAll() - IE 8 (partial) IE9 and above.

I explain both why you would want to call a PowerShell script from a batch file and how to do it in my blog post here.

This is basically what you are looking for:

PowerShell -NoProfile -ExecutionPolicy Bypass -Command "& 'C:\Users\SE\Desktop\ps.ps1'"

And if you need to run your PowerShell script as an admin, use this:

PowerShell -NoProfile -ExecutionPolicy Bypass -Command "& {Start-Process PowerShell -ArgumentList '-NoProfile -ExecutionPolicy Bypass -File ""C:\Users\SE\Desktop\ps.ps1""' -Verb RunAs}"

Rather than hard-coding the entire path to the PowerShell script though, I recommend placing the batch file and PowerShell script file in the same directory, as my blog post describes.

Problems with other answers:

• unsafe JSON.parse
• no response code checking

All of the answers here use JSON.parse() in an unsafe way. You should always put all calls to JSON.parse() in a try/catch block especially when you parse JSON coming from an external source, like you do here.

You can use request to parse the JSON automatically which wasn't mentioned here in other answers. There is already an answer using request module but it uses JSON.parse() to manually parse JSON - which should always be run inside a try {} catch {} block to handle errors of incorrect JSON or otherwise the entire app will crash. And incorrect JSON happens, trust me.

Other answers that use http also use JSON.parse() without checking for exceptions that can happen and crash your application.

Below I'll show few ways to handle it safely.

All examples use a public GitHub API so everyone can try that code safely.

Example with request

Here's a working example with request that automatically parses JSON:

'use strict';
var request = require('request');

var url = 'https://api.github.com/users/rsp';

request.get({
    url: url,
    json: true,
    headers: {'User-Agent': 'request'}
  }, (err, res, data) => {
    if (err) {
      console.log('Error:', err);
    } else if (res.statusCode !== 200) {
      console.log('Status:', res.statusCode);
    } else {
      // data is already parsed as JSON:
      console.log(data.html_url);
    }
});

Example with http and try/catch

This uses https - just change https to http if you want HTTP connections:

'use strict';
var https = require('https');

var options = {
    host: 'api.github.com',
    path: '/users/rsp',
    headers: {'User-Agent': 'request'}
};

https.get(options, function (res) {
    var json = '';
    res.on('data', function (chunk) {
        json += chunk;
    });
    res.on('end', function () {
        if (res.statusCode === 200) {
            try {
                var data = JSON.parse(json);
                // data is available here:
                console.log(data.html_url);
            } catch (e) {
                console.log('Error parsing JSON!');
            }
        } else {
            console.log('Status:', res.statusCode);
        }
    });
}).on('error', function (err) {
      console.log('Error:', err);
});

Example with http and tryjson

This example is similar to the above but uses the tryjson module. (Disclaimer: I am the author of that module.)

'use strict';
var https = require('https');
var tryjson = require('tryjson');

var options = {
    host: 'api.github.com',
    path: '/users/rsp',
    headers: {'User-Agent': 'request'}
};

https.get(options, function (res) {
    var json = '';

    res.on('data', function (chunk) {
        json += chunk;
    });

    res.on('end', function () {
        if (res.statusCode === 200) {
            var data = tryjson.parse(json);
            console.log(data ? data.html_url : 'Error parsing JSON!');
        } else {
            console.log('Status:', res.statusCode);
        }
    });
}).on('error', function (err) {
      console.log('Error:', err);
});

Summary

The example that uses request is the simplest. But if for some reason you don't want to use it then remember to always check the response code and to parse JSON safely.

Using my answer from here: https://stackoverflow.com/a/18031868/2362361

It would be important to know to which iface you want the MAC for since many can exist (bluetooth, several nics, etc.).

This does the job when you know the IP of the iface you need the MAC for, using netifaces (available in PyPI):

import netifaces as nif
def mac_for_ip(ip):
    'Returns a list of MACs for interfaces that have given IP, returns None if not found'
    for i in nif.interfaces():
        addrs = nif.ifaddresses(i)
        try:
            if_mac = addrs[nif.AF_LINK][0]['addr']
            if_ip = addrs[nif.AF_INET][0]['addr']
        except IndexError, KeyError: #ignore ifaces that dont have MAC or IP
            if_mac = if_ip = None
        if if_ip == ip:
            return if_mac
    return None

Testing:

>>> mac_for_ip('169.254.90.191')
'2c:41:38:0a:94:8b'

You will have to use javascript, or the JQuery framework to do that. her is an example using Jquery

   $('#toggle').click(function () {
        //check if checkbox is checked
        if ($(this).is(':checked')) {

            $('#sendNewSms').removeAttr('disabled'); //enable input

        } else {
            $('#sendNewSms').attr('disabled', true); //disable input
        }
    });

With JUnit5 I think the best way is to @ExtendWith(MockitoExtension.class) with @Mock in the method parameter or the field.

The following example demonstrates that with Hamcrest matchers.

See https://www.vogella.com/tutorials/Mockito/article.html for the required Maven/Gradle dependencies.

Another way of solving this is to use the DictReader class, which "skips" the header row and uses it to allowed named indexing.

Given "foo.csv" as follows:

FirstColumn,SecondColumn
asdf,1234
qwer,5678

Use DictReader like this:

import csv
with open('foo.csv') as f:
    reader = csv.DictReader(f, delimiter=',')
    for row in reader:
        print(row['FirstColumn'])  # Access by column header instead of column number
        print(row['SecondColumn'])

For Ubuntu 18.04 or PHP 7.2 users you can do:

apt-get install php7.2-curl

You can check your PHP version by running php -v to verify your PHP version and get the right curl version.

Do mean to check if $a is a non-empty string? So that it contains just any text? Then the following will work.

If $a contains a string, you can use the following:

if (!empty($a)) {      // Means: if not empty
    ...
}

If you also need to confirm that $a is actually a string, use:

if (is_string($a) && !empty($a)) {      // Means: if $a is a string and not empty
    ...
}

Try this:

$("input").bind({
            paste : function(){
                $('#eventresult').text('paste behaviour detected!');
            }
})

You can either pass request reverse('view-name', request=request) or enclose reverse() with build_absolute_uri request.build_absolute_uri(reverse('view-name'))

found will be npos in case of failure to find the substring in the search string.

An alternative if you sometimes do not have spaces do not want to use the CASE statement

select REVERSE(RIGHT(REVERSE(YourColumn), LEN(YourColumn) - CHARINDEX(' ', REVERSE(YourColumn))))

This works in SQL Server, and according to my searching MySQL has the same functions

For me, I always choose non-thread safe version because I always use nginx, or run PHP from the command line.

The non-thread safe version should be used if you install PHP as a CGI binary, command line interface or other environment where only a single thread is used.

A thread-safe version should be used if you install PHP as an Apache module in a worker MPM (multi-processing model) or other environment where multiple PHP threads run concurrently.

abs() : Returns the absolute value as per the argument i.e. if argument is int then it returns int, if argument is float it returns float. Also it works on complex variable also i.e. abs(a+bj) also works and returns absolute value i.e.math.sqrt(((a)**2)+((b)**2)

math.fabs() : It only works on the integer or float values. Always returns the absolute float value no matter what is the argument type(except for the complex numbers).

Basically, there are two ways to clear the cache:

<form autocomplete="off"></form>

or

$('#Textfiledid').attr('autocomplete', 'off');

template<typename T>
string str(T begin, T end)
{
    stringstream ss;
    bool first = true;
    for (; begin != end; begin++)
    {
        if (!first)
            ss << ", ";
        ss << *begin;
        first = false;
    }
    return ss.str();
}

This is the str function that can make integers turn into a string and not into a char for what the integer represents. Also works for doubles.

xlBook.Save();
xlBook.Close(true);
xlApp.Quit();
System.Runtime.InteropServices.Marshal.ReleaseComObject(xlApp);

try this.. it worked for me... you should release that xl application object to stop the process.

Maybe this article can help you http://blog.angular-university.io/introduction-to-angular-2-forms-template-driven-vs-model-driven/

In this approach, you have to use FormControl then watch for value changes and then apply your mask to the value. An example should be:

...
form: FormGroup;
...


ngOnInit(){
    this.form.valueChanges
            .map((value) => {
                // Here you can manipulate your value
                value.firstName = value.firstName.trim();
                return value;
            })
            .filter((value) => this.form.valid)
            .subscribe((value) => {
               console.log("Model Driven Form valid value: vm = ",JSON.stringify(value));
            });

}

You can find those maven properties in the super pom.

You find the jar here:

${M2_HOME}/lib/maven-model-builder-3.0.3.jar

Open the jar with 7-zip or some other archiver (or use the jar tool).

Navigate to

org/apache/maven/model

There you'll find the pom-4.0.0.xml.

It contains all those "short cuts":

<project>
    ...
    <build>
        <directory>${project.basedir}/target</directory>
        <outputDirectory>${project.build.directory}/classes</outputDirectory>
        <finalName>${project.artifactId}-${project.version}</finalName>
        <testOutputDirectory>${project.build.directory}/test-classes</testOutputDirectory>
        <sourceDirectory>${project.basedir}/src/main/java</sourceDirectory>
        <scriptSourceDirectory>src/main/scripts</scriptSourceDirectory>
        <testSourceDirectory>${project.basedir}/src/test/java</testSourceDirectory>
        <resources>
            <resource>
                <directory>${project.basedir}/src/main/resources</directory>
            </resource>
        </resources>
        <testResources>
            <testResource>
                <directory>${project.basedir}/src/test/resources</directory>
            </testResource>
        </testResources>
        ...
    </build>
    ...
</project>

Update

After some lobbying I am adding a link to the pom-4.0.0.xml. This allows you to see the properties without opening up the local jar file.

Run vim from the terminal. For the basics, you're advised to run the command vimtutor.

# On your terminal command line:
$ vim

If you have a specific file to edit, pass it as an argument.

$ vim yourfile.cpp

Likewise, launch the tutorial

$ vimtutor

You could ignore SIGINTs after shutdown starts by calling signal.signal(signal.SIGINT, signal.SIG_IGN) before you start your cleanup code.

I think the best easy way in this case is to use parseToStringDate which is part of GDK (Groovy JDK enhancements):

Parse a String matching the pattern EEE MMM dd HH:mm:ss zzz yyyy containing US-locale-constants only (e.g. Sat for Saturdays). Such a string is generated by the toString method of Date

Example:

println(Date.parseToStringDate("Tue Aug 10 16:02:43 PST 2010").format('MM-dd-yyyy'))

OpenGL should be present already - it will probably be Freeglut / GLUT that is missing.

GLUT is very dated now and not actively supported - so you should certainly be using Freeglut instead. You won't have to change your code at all, and a few additional features become available.

You'll find pre-packaged sets of files from here: http://freeglut.sourceforge.net/index.php#download If you don't see the "lib" folder, it's because you didn't download the pre-packaged set. "Martin Payne's Windows binaries" is posted at above link and works on Windows 8.1 with Visual Studio 2013 at the time of this writing.

When you download these you'll find that the Freeglut folder has three subfolders: - bin folder: this contains the dll files for runtime - include: the header files for compilation - lib: contains library files for compilation/linking

Installation instructions usually suggest moving these files into the visual studio folder and the Windows system folder: It is best to avoid doing this as it makes your project less portable, and makes it much more difficult if you ever need to change which version of the library you are using (old projects might suddenly stop working, etc.)

Instead (apologies for any inconsistencies, I'm basing these instructions on VS2010)... - put the freeglut folder somewhere else, e.g. C:\dev - Open your project in Visual Studio - Open project properties - There should be a tab for VC++ Directories, here you should add the appropriate include and lib folders, e.g.: C:\dev\freeglut\include and C:\dev\freeglut\lib - (Almost) Final step is to ensure that the opengl lib file is actually linked during compilation. Still in project properties, expand the linker menu, and open the input tab. For Additional Dependencies add opengl32.lib (you would assume that this would be linked automatically just by adding the include GL/gl.h to your project, but for some reason this doesn't seem to be the case)

At this stage your project should compile OK. To actually run it, you also need to copy the freeglut.dll files into your project folder

A lot of Discussions Happening here & there but I don't see some proper solution for this problem. Finally Ended up by writing a small Jquery + CSS code for doing this HACK on IE & Firefox.

Calculate Element Width (SELECT Element) using Jquery. Add a Wrapper Around Select Element and Keep overflow hidden for this element. Make sure that Width of this wrapper is appox. 25px less as that of SELECT Element. This could be easily done with Jquery. So Now Our Icon is Gone..! and it is time for adding our image icon on SELECT element...!!! Just add few simple lines for adding background and you are all Done..!! Make sure to use overflow hidden for outer wrapper,

Here is a Sample of Code which was done for Drupal. However could be used for others also by removing few lines of code which is Drupal Specific.

/*
 * Jquery Code for Removing Dropdown Arrow.
 * @by: North Web Studio
 */
(function($) {
  Drupal.behaviors.nwsJS = {
    attach: function(context, settings) {
      $('.form-select').once('nws-arrow', function() {
        $wrap_width = $(this).outerWidth();
        $element_width = $wrap_width + 20;
        $(this).css('width', $element_width);
        $(this).wrap('<div class="nws-select"></div>');
        $(this).parent('.nws-select').css('width', $wrap_width);
      });
    }
  };
})(jQuery);

/*
 * CSS Code for Removing Dropdown Arrow.
 * @by: North Web Studio
 */

.nws-select {
  border: 1px solid #ccc;
  overflow: hidden;
  background: url('../images/icon.png') no-repeat 95% 50%;
}
.nws-select .form-select {
  border: none;
  background: transparent;
}

Solution works on All Browsers IE, Chrome & Firefox No need of Adding fixed Widths Hacks Using CSS. It is all being handled Dynamically using JQuery.!

If you need avoid floating point problem on rounding numbers for accounting, you can use numpy round.

You need install numpy :

pip install numpy

and the code :

import numpy as np

print(round(2.675, 2))
print(float(np.round(2.675, 2)))

prints

2.67
2.68

You should use that if you manage money with legal rounding.

Valentin Rocher's method works if you've extended your view, but if you're using an event listener, use this:

view.setOnTouchListener(new OnTouchListener()
{
    public boolean onTouch(View v, MotionEvent event)
    {
        Toast toast = Toast.makeText(
            getApplicationContext(), 
            "View touched", 
            Toast.LENGTH_LONG
        );
        toast.show();

        return true;
    }
});


// Obtain MotionEvent object
long downTime = SystemClock.uptimeMillis();
long eventTime = SystemClock.uptimeMillis() + 100;
float x = 0.0f;
float y = 0.0f;
// List of meta states found here: developer.android.com/reference/android/view/KeyEvent.html#getMetaState()
int metaState = 0;
MotionEvent motionEvent = MotionEvent.obtain(
    downTime, 
    eventTime, 
    MotionEvent.ACTION_UP, 
    x, 
    y, 
    metaState
);

// Dispatch touch event to view
view.dispatchTouchEvent(motionEvent);

For more on obtaining a MotionEvent object, here is an excellent answer: Android: How to create a MotionEvent?

But how do I run this? I tried typing: sudo chkconfig.install which doesn't work.

I'm not sure where you got this package or what it contains; A url of download would be helpful. Without being able to look at the contents of chkconfig.install; I'm surprised to find a unix tool like chkconfig to be bundled in a zip archive, maybe it is still yet to be uncompressed, a tar.gz? but maybe it is a shell script?

I should suggest editing it and seeing what you are executing.

sh chkconfig.install or ./chkconfig.install ; which might work....but my suggestion would be to learn to use update-rc.d as the other answers have suggested but do not speak directly to the question...which is pretty hard to answer without being able to look at the data yourself.

I'm also in favour of a ISO/IEC 11179 style naming convention, noting they are guidelines rather than being prescriptive.

See Data element name on Wikipedia:

"Tables are Collections of Entities, and follow Collection naming guidelines. Ideally, a collective name is used: eg., Personnel. Plural is also correct: Employees. Incorrect names include: Employee, tblEmployee, and EmployeeTable."

As always, there are exceptions to rules e.g. a table which always has exactly one row may be better with a singular name e.g. a config table. And consistency is of utmost importance: check whether you shop has a convention and, if so, follow it; if you don't like it then do a business case to have it changed rather than being the lone ranger.

Instead of modifying the height and width attributes of the image, try modifying the CSS height and width.

myimg = document.getElementById('myimg');
myimg.style.height = "50px";
myimg.style.width = "50px";

One common "gotcha" is that the height and width styles are strings that include a unit, like "px" in the example above.

Edit - I think that setting the height and width directly instead of using style.height and style.width should work. It would also have the advantage of already having the original dimensions. Can you post a bit of your code? Are you sure you're in standards mode instead of quirks mode?

This should work:

myimg = document.getElementById('myimg');
myimg.height = myimg.height * 2;
myimg.width = myimg.width * 2;

Here is quick and dirty color generator in C# (using 'RYB approach' described in this article). It's a rewrite from JavaScript.

Use:

List<Color> ColorPalette = ColorGenerator.Generate(30).ToList();

First two colors tend to be white and a shade of black. I often skip them like this (using Linq):

List<Color> ColorsPalette = ColorGenerator
            .Generate(30)
            .Skip(2) // skip white and black
            .ToList(); 

Implementation:

public static class ColorGenerator
{

    // RYB color space
    private static class RYB
    {
        private static readonly double[] White = { 1, 1, 1 };
        private static readonly double[] Red = { 1, 0, 0 };
        private static readonly double[] Yellow = { 1, 1, 0 };
        private static readonly double[] Blue = { 0.163, 0.373, 0.6 };
        private static readonly double[] Violet = { 0.5, 0, 0.5 };
        private static readonly double[] Green = { 0, 0.66, 0.2 };
        private static readonly double[] Orange = { 1, 0.5, 0 };
        private static readonly double[] Black = { 0.2, 0.094, 0.0 };

        public static double[] ToRgb(double r, double y, double b)

Dictionaries in python have no order. You could use a list of tuples as your data structure instead.

d = { 'a': 10, 'b': 20, 'c': 30}
newd = [('a',10), ('b',20), ('c',30)]

Then this code could be used to find the locations of keys with a specific value

locations = [i for i, t in enumerate(newd) if t[0]=='b']

>>> [1]

I think you've got one major problem here: there's no monotonically increasing "counter" to guarantee that a given row has happened later in time than another. Take this example:

timestamp   lives_remaining   user_id   trans_id
10:00       4                 3         5
10:00       5                 3         6
10:00       3                 3         1
10:00       2                 3         2

You cannot determine from this data which is the most recent entry. Is it the second one or the last one? There is no sort or max() function you can apply to any of this data to give you the correct answer.

Increasing the resolution of the timestamp would be a huge help. Since the database engine serializes requests, with sufficient resolution you can guarantee that no two timestamps will be the same.

Alternatively, use a trans_id that won't roll over for a very, very long time. Having a trans_id that rolls over means you can't tell (for the same timestamp) whether trans_id 6 is more recent than trans_id 1 unless you do some complicated math.

In my case, I ported a project from Windows to OSX, using Visual Studio Community 7.1.5 for Mac. What did the trick was disabling the Use MSBuild engine (recommended for this type of project)option on the project preferences:

Updated ES6 version

const truncateString = (string, maxLength = 50) => {
  if (!string) return null;
  if (string.length <= maxLength) return string;
  return `${string.substring(0, maxLength)}...`;
};

truncateString('what up', 4); // returns 'what...'

It is all but satisfying, isn't it? The easiest way I have found to specify when setting the context, e.g.:

sns.set_context("paper", rc={"font.size":8,"axes.titlesize":8,"axes.labelsize":5})   

This should take care of 90% of standard plotting usage. If you want ticklabels smaller than axes labels, set the 'axes.labelsize' to the smaller (ticklabel) value and specify axis labels (or other custom elements) manually, e.g.:

axs.set_ylabel('mylabel',size=6)

you could define it as a function and load it in your scripts so you don't have to remember your standard numbers, or call it every time.

def set_pubfig:
    sns.set_context("paper", rc={"font.size":8,"axes.titlesize":8,"axes.labelsize":5})   

Of course you can use configuration files, but I guess the whole idea is to have a simple, straightforward method, which is why the above works well.

Note: If you specify these numbers, specifying font_scale in sns.set_context is ignored for all specified font elements, even if you set it.

I had the same issue, virtualenv was pointing to an old python path. Fixing the path resolved the issue:

$ virtualenv -p python2.7 env
-bash: /usr/local/bin/virtualenv: /usr/local/opt/python/bin/python2.7: bad interpreter: No such file or directory

$ which python2.7
/opt/local/bin/python2.7

# needed to change to correct python path
$ head  /usr/local/bin/virtualenv
#!/usr/local/opt/python/bin/python2.7 <<<< REMOVED THIS LINE
#!/opt/local/bin/python2.7 <<<<< REPLACED WITH CORRECT PATH

# now it works:
$ virtualenv -p python2.7 env
Running virtualenv with interpreter /opt/local/bin/python2.7
New python executable in env/bin/python
Installing setuptools, pip...done.

How to update in codeignitor?

whenever you want to update same status with multiple rows you use where_in insteam of where or if you want to change only single record can use where.

below is my code

$conditionArray = array(1, 3, 4, 6);
$this->db->where_in("ip_id", $conditionArray);
$this->db->update($this->table, array("status" => 'active'));

its working perfect.

As for this date (February 2017), it seems that mailchimp has integrated something similar to what gbinflames suggests into their own javascript generated form.

You don't need any further intervention now as mailchimp will convert the form to an ajax submitted one when javascript is enabled.

All you need to do now is just paste the generated form from the embed menu into your html page and NOT modify or add any other code.

This simply works. Thanks MailChimp!

@AlexCuse I wanted to add this as comment to your answer but gave up after making multiple failed attempt to add newlines in comments.

That said, t1ID is unique in table_1 but that doesn't makes it unique in INFO table as well.

For example:

Table_1 has:
Id Field
1 A
2 B

Table_2 has:
Id Field
1 X
2 Y

INFO then can have:
t1ID t2ID field
1 1 some
1 2 data
2 1 in-each
2 2 row

So in INFO table to uniquely identify a row you need both t1ID and t2ID

I'd like to make some changes: In C, you can use the built in qsort command:

int compare( const void* a, const void* b)
{
   int int_a = * ( (int*) a );
   int int_b = * ( (int*) b );

   // an easy expression for comparing
   return (int_a > int_b) - (int_a < int_b);
}

qsort( a, 6, sizeof(int), compare )

A more public way is by calling get_form in Admin classes. It also works for non-database fields too. For example here i have a field called '_terminal_list' on the form that can be used in special cases for choosing several terminal items from get_list(request), then filtering based on request.user:

class ChangeKeyValueForm(forms.ModelForm):  
    _terminal_list = forms.ModelMultipleChoiceField( 
queryset=Terminal.objects.all() )

    class Meta:
        model = ChangeKeyValue
        fields = ['_terminal_list', 'param_path', 'param_value', 'scheduled_time',  ] 

class ChangeKeyValueAdmin(admin.ModelAdmin):
    form = ChangeKeyValueForm
    list_display = ('terminal','task_list', 'plugin','last_update_time')
    list_per_page =16

    def get_form(self, request, obj = None, **kwargs):
        form = super(ChangeKeyValueAdmin, self).get_form(request, **kwargs)
        qs, filterargs = Terminal.get_list(request)
        form.base_fields['_terminal_list'].queryset = qs
        return form

Right click on Editor then Select Source -> Generate Getters and Setters or press Alt + Shift + S

The simple way is:

import numpy as np
np.exp(np.log(your_array).sum())

Installing a newer release of IDEA Community (2018.3 instead of 2017.x) was solved my issue with same error but java version:11. Reimport hadn't worked for me. But it worth a try.

lets say you have a model called Book and on it a field called 'cover_pic', in that case, you can do the following to compress the image:

from PIL import Image
b = Book.objects.get(title='Into the wild')
image = Image.open(b.cover_pic.path)
image.save(b.image.path,quality=20,optimize=True)

hope it helps to anyone stumbling upon it.

Implementation in Java : Using codaddict's algorithm (Maybe slightly different)

import java.util.HashMap;

public class ArrayPairSum {


public static void main(String[] args) {        

    int []a = {2,45,7,3,5,1,8,9};
    printSumPairs(a,10);        

}


public static void printSumPairs(int []input, int k){
    Map<Integer, Integer> pairs = new HashMap<Integer, Integer>();

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

        if(pairs.containsKey(input[i]))
            System.out.println(input[i] +", "+ pairs.get(input[i]));
        else
            pairs.put(k-input[i], input[i]);
    }

}
}

For input = {2,45,7,3,5,1,8,9} and if Sum is 10

Output pairs:

3,7 
8,2
9,1

Some notes about the solution :

• We iterate only once through the array --> O(n) time
• Insertion and lookup time in Hash is O(1).
• Overall time is O(n), although it uses extra space in terms of hash.

The commands for what specific codes to run are listed inside your package.json file under scripts. Here is an example of mine:

"scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint"
  },

If you are looking to run your site locally, you can test it with

npm serve

If you are looking to prep your site for production, you would use

npm build

This command will generate a dist folder that has a compressed version of your site.

Aditionally to the answer from @srk, you should uninstall package setuptools:

python -m pip uninstall pip setuptools

If you want to uninstall all other packages first, this answer has some hints: https://stackoverflow.com/a/11250821/265954

Note: before you use the commands from that answer, please carefully read the comments about side effects and how to avoid uninstalling pip and setuptools too early. E.g. pip freeze | grep -v "^-e" | grep -v "^(setuptools|pip)" | xargs pip uninstall -y

You can handle this without requiring a user input.

Step 1. Create a ManualRestEvent at the start of Main thread

ManualResetEvent manualResetEvent = new ManualResetEvent(false);

Step 2 . Wait ManualResetEvent

manualResetEvent.WaitOne();

Step 3.To Stop

manualResetEvent.Set();

Is this what you're looking for?

if (request instanceof HttpServletRequest) {
 String url = ((HttpServletRequest)request).getRequestURL().toString();
 String queryString = ((HttpServletRequest)request).getQueryString();
}

To Reconstruct:

System.out.println(url + "?" + queryString);

Info on HttpServletRequest.getRequestURL() and HttpServletRequest.getQueryString().

From Java 8 onwards we have CompletableFuture. On your case, you may use the method supplyAsync to get the result after execution.

Please find some reference here.

    CompletableFuture<Integer> completableFuture
      = CompletableFuture.supplyAsync(() -> yourMethod());

   completableFuture.get() //gives you the value

You can use this (or any variant):

Files.copy(src, dst, StandardCopyOption.REPLACE_EXISTING);

Also, I'd recommend using File.separator or / instead of \\ to make it compliant across multiple OS, question/answer on this available here.

Since you're not sure how to temporarily store files, take a look at ArrayList:

List<File> files = new ArrayList();
files.add(foundFile);

To move a List of files into a single directory:

List<File> files = ...;
String path = "C:/destination/";
for(File file : files) {
    Files.copy(file.toPath(),
        (new File(path + file.getName())).toPath(),
        StandardCopyOption.REPLACE_EXISTING);
}

You can either quote it like your Windows example above, or escape the spaces with backslashes:

 "/foo folder with space/foo" --help
 /foo\ folder\ with\ space/foo --help

QPushButton *button = new QPushButton;
button->setIcon(QIcon(":/icons/..."));
button->setIconSize(QSize(65, 65));

You can do:

setContentPane(new JLabel(new ImageIcon("resources/taverna.jpg")));

At first line of the Jframe class constructor, that works fine for me

This is really old, but <font size="10"> would be about <p style= "font-size:55px">

Though the question is old enough it still can be referenced nowdays.

Semantically that is exactly what Java 12 introduced (https://openjdk.java.net/jeps/325), thus, exactly in that simple example provided I can't see any problem or cons.

I guess you want user to be redirected to ~/AreaZ URL once (s)he has visited ~/ URL. I'd achieve by means of the following code within your root HomeController.

public class HomeController
{
    public ActionResult Index()
    {
        return RedirectToAction("ActionY", "ControllerX", new { Area = "AreaZ" });
    }
}

And the following route in Global.asax.

routes.MapRoute(
    "Redirection to AreaZ",
    String.Empty,
    new { controller = "Home ", action = "Index" }
);

for(int j=0;j<30;j++) {
    LinearLayout childLayout = new LinearLayout(MainActivity.this);
    LinearLayout.LayoutParams linearParams = new LinearLayout.LayoutParams(
        LayoutParams.WRAP_CONTENT,
        LayoutParams.WRAP_CONTENT);
    childLayout.setLayoutParams(linearParams);

    TextView mType = new TextView(MainActivity.this);
    TextView mValue = new TextView(MainActivity.this);

    mType.setLayoutParams(new TableLayout.LayoutParams(
        LayoutParams.WRAP_CONTENT,
        LayoutParams.WRAP_CONTENT, 1f));
    mValue.setLayoutParams(new TableLayout.LayoutParams(
        LayoutParams.WRAP_CONTENT,
        LayoutParams.WRAP_CONTENT, 1f));

    mType.setTextSize(17);
    mType.setPadding(5, 3, 0, 3);
    mType.setTypeface(Typeface.DEFAULT_BOLD);
    mType.setGravity(Gravity.LEFT | Gravity.CENTER);

    mValue.setTextSize(16);
    mValue.setPadding(5, 3, 0, 3);
    mValue.setTypeface(null, Typeface.ITALIC);
    mValue.setGravity(Gravity.LEFT | Gravity.CENTER);

    mType.setText("111");
    mValue.setText("111");

    childLayout.addView(mValue, 0);
    childLayout.addView(mType, 0);

    linear.addView(childLayout);
}

I'm loving all the solutions posted here, but I solved this using Conditional Formatting as a percentage-based Data Bar.

This is applied to a row of cells as shown below. The cells that include 0% and 100% are normally hidden, because they're just there to give the "ScanProgress" named range (Left) context.

In the code I'm looping through a table doing some stuff.

For intRow = 1 To shData.Range("tblData").Rows.Count

    shData.Range("ScanProgress").Value = intRow / shData.Range("tblData").Rows.Count
    DoEvents

    ' Other processing

Next intRow

Minimal code, looks decent.

You could use the copy() function :

// Will copy foo/test.php to bar/test.php
// overwritting it if necessary
copy('foo/test.php', 'bar/test.php');

Quoting a couple of relevant sentences from its manual page :

Makes a copy of the file source to dest.

If the destination file already exists, it will be overwritten.

Following worked for me..

1. Ensure you are not using Safe-mode in your query editor application. If you are, disable it!
2. Then run following sql command

for a table say, 'test_update_cmd', source value column col2, target value column col1 and condition column col3: -

UPDATE  test_update_cmd SET col1=col2 WHERE col3='value';

Good Luck!

Format the redirect URL in the following way:

stuff.mysite.org.uk$S$Q

The $S will say that any path must be applied to the new URL. $Q says that any parameter variables must be passed to the new URL.

In IIS 7.0, you must enable the option Redirect to exact destination. I believe there must be an option like this in IIS 6.0 too.

Just delete .npmrc folder in c:users>'username' and try running the command it will be resolved !

Select * from Table1 left join Table2 ...

and

Select * from Table2 right join Table1 ...

are indeed completely interchangeable. Try however Table2 left join Table1 (or its identical pair, Table1 right join Table2) to see a difference. This query should give you more rows, since Table2 contains a row with an id which is not present in Table1.

Note: If you have written any crash handler yourself, then the core might not get generated. So search for code with something on the line:

signal(SIGSEGV, <handler> );

so the SIGSEGV will be handled by handler and you will not get the core dump.

From the spec, §15.9.1.1:

A Date object contains a Number indicating a particular instant in time to within a millisecond. Such a Number is called a time value. A time value may also be NaN, indicating that the Date object does not represent a specific instant of time.

Time is measured in ECMAScript in milliseconds since 01 January, 1970 UTC. In time values leap seconds are ignored. It is assumed that there are exactly 86,400,000 milliseconds per day. ECMAScript Number values can represent all integers from –9,007,199,254,740,992 to 9,007,199,254,740,992; this range suffices to measure times to millisecond precision for any instant that is within approximately 285,616 years, either forward or backward, from 01 January, 1970 UTC.

The actual range of times supported by ECMAScript Date objects is slightly smaller: exactly –100,000,000 days to 100,000,000 days measured relative to midnight at the beginning of 01 January, 1970 UTC. This gives a range of 8,640,000,000,000,000 milliseconds to either side of 01 January, 1970 UTC.

The exact moment of midnight at the beginning of 01 January, 1970 UTC is represented by the value +0.

The third paragraph being the most relevant. Based on that paragraph, we can get the precise earliest date per spec from new Date(-8640000000000000), which is Tuesday, April 20th, 271,821 BCE (BCE = Before Common Era, e.g., the year -271,821).

        var taskModelUrl = 'api/task/';
        return {
            rest: {
                taskUpload: $resource(taskModelUrl, {
                    id: '@id'
                }, {
                    save: {
                        method: "POST",
                        isArray: false,
                        headers: {"Content-Type": undefined},
                        transformRequest: angular.identity
                    }
                })
            }
        };
    }
]);

And then use it in a module:

task.module.js

$ngModelTask.controller("taskController", [
    "$scope",
    "$taskService",
    function (
        $scope,
        $taskService,
    ) {
    $scope.saveTask = function (name, file) {
        var newTask,
            payload = new FormData();
        payload.append("name", name);
        payload.append("file", file);
        newTask = $taskService.rest.taskUpload.save(payload);
        // check if exists
    }
}

Try this code:

import java.util.Scanner;

public class BasicElement {
    public static void main(String[] args){
        Scanner input = new Scanner(System.in);
        int hours;
        System.out.print("Enter the hours to convert:");
        hours =input.nextInt();
        int d=hours/24;
        int m=hours%24;
        System.out.println(d+"days"+" "+m+"hours");     

    }
}

matches return true if the whole string matches the given pattern. find tries to find a substring that matches the pattern.

INSERT INTO dues_storage
SELECT field1, field2, ..., fieldN, CURRENT_DATE()

You could use DateTime.TryParse() instead of DateTime.Parse().
With TryParse() you have a return value if it was successful and with Parse() you have to handle an exception

I have recently tried the following approach which seems to work fine, although I am not 100% sure if there might be any side effects:

'use strict';

import * as models from "../../models";

module.exports = {

  up: function (queryInterface, Sequelize) {

    return queryInterface.createTable(models.Role.tableName, models.Role.attributes)
    .then(() => queryInterface.createTable(models.Team.tableName, models.Team.attributes))
    .then(() => queryInterface.createTable(models.User.tableName, models.User.attributes))

  },

  down: function (queryInterface, Sequelize) {
    ...
  }

};

When running the migration above using sequelize db:migrate, my console says:

Starting 'db:migrate'...
Finished 'db:migrate' after 91 ms
== 20160113121833-create-tables: migrating =======
== 20160113121833-create-tables: migrated (0.518s)

All the tables are there, everything (at least seems to) work as expected. Even all the associations are there if they are defined correctly.

Apart from the Distinct extension method of LINQ, you could use a HashSet<T> object that you initialise with your collection. This is most likely more efficient than the LINQ way, since it uses hash codes (GetHashCode) rather than an IEqualityComparer).

In fact, if it's appropiate for your situation, I would just use a HashSet for storing the items in the first place.

Oddly enough, the issue for me was I was trying to open 2012 SQL Server Integration Services on SSMS 2008 R2. When I opened the same in SSMS 2012, it connected right away.

After Much Fannying about, deleting this that etc, I found the way to delete a "website" from your list (which is, in fact what the original question was - minus all the flaffing) is

• Select the Account (Website) that you want to delete
• In the first column (left hand one)
• Click Account Settings
• Down the bottom, it says Delete this account.

That's it… Done.

Remember: for this exercise only Account means Website.

A rather nice addition to @MartijnPieters answer is to get back a dictionary sorted by occurrence since Collections.most_common only returns a tuple. I often couple this with a json output for handy log files:

from collections import Counter, OrderedDict

x = Counter({'a':5, 'b':3, 'c':7})
y = OrderedDict(x.most_common())

With the output:

OrderedDict([('c', 7), ('a', 5), ('b', 3)])
{
  "c": 7, 
  "a": 5, 
  "b": 3
}

By turning them into integers instead:

percent = (int(pyc) / int(tpy)) * 100;

In python 3, the input() function returns a string. Always. This is a change from Python 2; the raw_input() function was renamed to input().

Use an on onkeypress event. Example for a zip code box. It allows a maximum of 5 characters, and checks to make sure input is only numbers.

Nothing beats a server side validation of course, but this is a nifty way to go.

function validInput(e) {_x000D_
  e = (e) ? e : window.event;_x000D_
  a = document.getElementById('zip-code');_x000D_
  cPress = (e.which) ? e.which : e.keyCode;_x000D_
_x000D_
  if (cPress > 31 && (cPress < 48 || cPress > 57)) {_x000D_
    return false;_x000D_
  } else if (a.value.length >= 5) {_x000D_
    return false;_x000D_
  }_x000D_
_x000D_
  return true;_x000D_
}

#zip-code {_x000D_
  overflow: hidden;_x000D_
  width: 60px;_x000D_
}

If you do not sure about [unowned self] then use [weak self]

$Group is an object, but you will actually need to check if $Group.samaccountname.StartsWith("string").

Change $Group.StartsWith("S_G_") to $Group.samaccountname.StartsWith("S_G_").

Here is a very easy and eficient way: add in your CSS your class with the colors you want to apply to your button:

.my-btn{
    background: #0099cc;
    color: #ffffff;
}
.my-btn:hover { 
  border-color: #C0C0C0; 
  background-color: #C0C0C0; 
}

and add the style to your bootstrap button or link:

<a href="xxx" class="btn btn-info my-btn">aaa</a>

some people talk very well about PyInstaller

http://www.pyinstaller.org/

That's because the color input only accepts three attributes: "primary", "accent" or "warn". Hence, you'll have to style the icons the CSS way:

1. Add a class to style your icon:

   .white-icon {
       color: white;
   }
   /* Note: If you're using an SVG icon, you should make the class target the `<svg>` element */
   .white-icon svg {
       fill: white;
   }
   

2. Add the class to your icon:

   <mat-icon class="white-icon">menu</mat-icon>
   

redirected uri is the location where the user will be redirected after successfully login to your app. for example to get access token for your app in facebook you need to subimt redirected uri which is nothing only the app Domain that your provide when you create your facebook app.

Yes there is 2MB max and it can be increased by configuration change like this. If your POST body is not in form of multipart file then you might need to add the max-http-post configuration for tomcat in the application yml configuration file.

Increase max size of each multipart file to 10MB and total payload size of 100MB max

 spring:
    servlet:
      multipart:max-file-size: 10MB
      multipart:max-request-size: 100MB
 

Setting max size of post requests which might just be the formdata in string format to ~10 MB

 server:
    tomcat:
        max-http-post-size: 100000000 # max-http-form-post-size: 10MB for new version

You might need to add this for the latest sprintboot version ->

server: tomcat: max-http-form-post-size: 10MB

If you want to check all of your input matches,

>>> all(x in ['b', 'a', 'foo', 'bar'] for x in ['a', 'b'])

if you want to check at least one match,

>>> any(x in ['b', 'a', 'foo', 'bar'] for x in ['a', 'b'])

out is more useful when you are trying to return an object that you declare in the method.

Example

public BookList Find(string key)
{
   BookList book; //BookList is a model class
   _books.TryGetValue(key, out book) //_books is a concurrent dictionary
                                     //TryGetValue gets an item with matching key and returns it into book.
   return book;
}

Looking at the exact rewrite was key for me. the wellKnownUrl lookup was returning "http://127.0.01:7070/" and I had specified "http://localhost:7070" ;-)

ORA-01861: literal does not match format string

This happens because you have tried to enter a literal with a format string, but the length of the format string was not the same length as the literal.

You can overcome this issue by carrying out following alteration.

TO_DATE('1989-12-09','YYYY-MM-DD')

As a general rule, if you are using the TO_DATE function, TO_TIMESTAMP function, TO_CHAR function, and similar functions, make sure that the literal that you provide matches the format string that you've specified

matrix multiplication, see the following example:

> A <- matrix (c(1,3,4, 5,8,9, 1,3,3), 3,3)
> A
     [,1] [,2] [,3]
[1,]    1    5    1
[2,]    3    8    3
[3,]    4    9    3
> 
> B <- matrix (c(2,4,5, 8,9,2, 3,4,5), 3,3)
> 
> B
     [,1] [,2] [,3]
[1,]    2    8    3
[2,]    4    9    4
[3,]    5    2    5
> 
> 
> A %*% B
     [,1] [,2] [,3]
[1,]   27   55   28
[2,]   53  102   56
[3,]   59  119   63

> B %*% A
     [,1] [,2] [,3]
[1,]   38  101   35
[2,]   47  128   43
[3,]   31   86   26

Also see:

http://en.wikipedia.org/wiki/Matrix_multiplication

If this does not follow the size of matrix rule you will get the error:

> A <- matrix(c(1,2,3,4,5,6), 3,2)
    > A
     [,1] [,2]
[1,]    1    4

Add a new user environment variable (Windows 7):

1. Start Menu > Control Panel > System > Advanced System Settings (on the left) > Environment Variables


2. Add a new user variable (at the top) that points your home user directory:

   Variable name: ANDROID_SDK_HOME
   Variable value: a path to a directory of your choice

AVD Manager will use this directory to save its .android directory into it.

For those who may be interested, I blogged about my first foray into Android development...
Android "Hello World": a Tale of Woe

Alternatively, you can use the Rapid Environment Editor to set the environment variables.

try This

setTimeout( function(){ 
    // call after 5 second 
  }  , 5000 );

How does your .NET Webservice look like?

I had the same effect using ksoap 2.3 from code.google.com. I followed the tutorial on The Code Project (which is great BTW.)

And everytime I used

    Integer result = (Integer)envelope.getResponse();

to get the result of a my webservice (regardless of the type, I tried Object, String, int) I ran into the org.ksoap2.serialization.SoapPrimitive exception.

I found a solution (workaround). The first thing I had to do was to remove the "SoapRpcMethod() attribute from my webservice methods.

    [SoapRpcMethod(), WebMethod]
    public Object GetInteger1(int i)
    {
        // android device will throw exception
        return 0;
    }

    [WebMethod]
    public Object GetInteger2(int i)
    {
        // android device will get the value
        return 0;
    }

Then I changed my Android code to:

    SoapPrimitive result = (SoapPrimitive)envelope.getResponse();

However, I get a SoapPrimitive object, which has a "value" filed that is private. Luckily the value is passed through the toString() method, so I use Integer.parseInt(result.toString()) to get my value, which is enough for me, because I don't have any complex types that I need to get from my Web service.

Here is the full source:

private static final String SOAP_ACTION = "http://tempuri.org/GetInteger2";
private static final String METHOD_NAME = "GetInteger2";
private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL = "http://10.0.2.2:4711/Service1.asmx";

public int GetInteger2() throws IOException, XmlPullParserException {
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

    PropertyInfo pi = new PropertyInfo();
    pi.setName("i");
    pi.setValue(123);
    request.addProperty(pi);

    SoapSerializationEnvelope envelope =
        new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.dotNet = true;
    envelope.setOutputSoapObject(request);

    AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(URL);
    androidHttpTransport.call(SOAP_ACTION, envelope);

    SoapPrimitive result = (SoapPrimitive)envelope.getResponse();
    return Integer.parseInt(result.toString());
}

Format specifier in printf should be %f for doubl datatypes since float datatyles eventually convert to double datatypes inside printf.

There is no provision to print float data. Please find the discussion here : Correct format specifier for double in printf

Try this as a shortcut, not as a definitive solution (see comments):

<script type="text/javascript">
    var ip = location.host;
    alert(ip);
</script>

This solution cannot work in some scenarios but it can help for quick testing. Regards

I use:

NSInteger stringToInt(NSString *string) {
    return [string integerValue];
}

And vice versa:

NSString* intToString(NSInteger integer) {
    return [NSString stringWithFormat:@"%d", integer];
}

<TextBlock Text="{Binding Date, StringFormat='{}{0:MM/dd/yyyy a\\t h:mm tt}'}" />

will return you

There are lots of things I have seen make a model diverge.

1. Too high of a learning rate. You can often tell if this is the case if the loss begins to increase and then diverges to infinity.

2. I am not to familiar with the DNNClassifier but I am guessing it uses the categorical cross entropy cost function. This involves taking the log of the prediction which diverges as the prediction approaches zero. That is why people usually add a small epsilon value to the prediction to prevent this divergence. I am guessing the DNNClassifier probably does this or uses the tensorflow opp for it. Probably not the issue.

3. Other numerical stability issues can exist such as division by zero where adding the epsilon can help. Another less obvious one if the square root who's derivative can diverge if not properly simplified when dealing with finite precision numbers. Yet again I doubt this is the issue in the case of the DNNClassifier.

4. You may have an issue with the input data. Try calling assert not np.any(np.isnan(x)) on the input data to make sure you are not introducing the nan. Also make sure all of the target values are valid. Finally, make sure the data is properly normalized. You probably want to have the pixels in the range [-1, 1] and not [0, 255].

5. The labels must be in the domain of the loss function, so if using a logarithmic-based loss function all labels must be non-negative (as noted by evan pu and the comments below).

I replaced the typedef (using to be specific) with inheritance and constructor inheritance (?).

Original

using CallStack = std::array<StackFrame, MAX_CALLSTACK_DEPTH>;

Replaced

struct CallStack // Not a typedef to allow forward declaration.
  : public std::array<StackFrame, MAX_CALLSTACK_DEPTH>
{
  typedef std::array<StackFrame, MAX_CALLSTACK_DEPTH> Base;
  using Base::Base;
};

This way I was able to forward declare CallStack with:

class CallStack;

If your window rootViewController is UITabbarController(which is in most cases) then you can access tabbar in didFinishLaunchingWithOptions in the AppDelegate file.

func application(application: UIApplication!, didFinishLaunchingWithOptions launchOptions: NSDictionary!) -> Bool {
    // Override point for customization after application launch.

    if let tabBarController = self.window!.rootViewController as? UITabBarController {
        tabBarController.selectedIndex = 1
    }

    return true
}

This will open the tab with the index given (1) in selectedIndex.

If you do this in viewDidLoad of your firstViewController, you need to manage by flag or another way to keep track of the selected tab. The best place to do this in didFinishLaunchingWithOptions of your AppDelegate file or rootViewController custom class viewDidLoad.

You can also just right click on the page in the browser and select "Inspect Element" to bring up the developer tools.

what about simply constructing your frame from a standard list ?

frame = bytes([0xA2,0x01,0x02,0x03,0x04])

the bytes() constructor can build a byte frame from an iterable containing int values. an iterable is anything which implements the iterator protocol: an list, an iterator, an iterable object like what is returned by range()...

React Router 4 includes a withRouter HOC that gives you access to the history object via this.props:

import React, {Component} from 'react'
import {withRouter} from 'react-router-dom'

class Foo extends Component {
  constructor(props) {
    super(props)

    this.goHome = this.goHome.bind(this)
  }

  goHome() {
    this.props.history.push('/')
  }

  render() {
    <div className="foo">
      <button onClick={this.goHome} />
    </div>
  }
}

export default withRouter(Foo)

I looked around for a solution to this for a while. It appears that the JDK doesn't have the Mozilla plugins (which is what Chrome uses) in it's installation. It is only in the JRE installation. There are a couple of DLLs that make up the plugin and they all start with np*

I found this to be the biggest help:

Use HAProxy 1.5 or newer, and simply add the following line to the frontend config:

Hear it from the Horse's Mouth : APUE (Richard Stevens).
To the kernel, all open files are referred to by File Descriptors. A file descriptor is a non-negative number.

When we open an existing file or create a new file, the kernel returns a file descriptor to the process. The kernel maintains a table of all open file descriptors, which are in use. The allotment of file descriptors is generally sequential and they are allotted to the file as the next free file descriptor from the pool of free file descriptors. When we closes the file, the file descriptor gets freed and is available for further allotment.
See this image for more details :

When we want to read or write a file, we identify the file with the file descriptor that was returned by open() or create() function call, and use it as an argument to either read() or write().
It is by convention that, UNIX System shells associates the file descriptor 0 with Standard Input of a process, file descriptor 1 with Standard Output, and file descriptor 2 with Standard Error.
File descriptor ranges from 0 to OPEN_MAX. File descriptor max value can be obtained with ulimit -n. For more information, go through 3rd chapter of APUE Book.

If you want to do rsync and use custom user and custom ssh key, you need to write this key in rsync options.

---
 - name: rsync
   hosts: serverA,serverB,serverC,serverD,serverE,serverF
   gather_facts: no
   vars:
     ansible_user: oracle
     ansible_ssh_private_key_file: ./mykey
     src_file: "/path/to/file.txt"
   tasks:
     - name: Copy Remote-To-Remote from serverA to server{B..F}
       synchronize:
           src:  "{{ src_file }}"
           dest: "{{ src_file }}"
           rsync_opts:
              - "-e ssh -i /remote/path/to/mykey"
       delegate_to: serverA

Just to add to the other answers, if you would prefer to return a vector rather than a dataframe, you have the following options:

dplyr < 0.7.0

Enclose the dplyr functions in a parentheses and combine it with $ syntax:

(mtcars %>% distinct(cyl))$cyl

dplyr >= 0.7.0

Use the pull verb:

mtcars %>% distinct(cyl) %>% pull()

I was using old version 1.0.beta.6 of handlebars, i think somewhere during 1.1 - 1.3 this functionality was added, so updating to 1.3.0 solved the issue, here is the usage:

Usage:

{{#each object}}
  Key {{@key}} : Value {{this}}
{{/people}}

By using this code we can setup MapView anywhere, inside any ViewPager or Fragment or Activity.

In the latest update of Google for Maps, only MapView is supported for fragments. MapFragment & SupportMapFragment doesn't work. I might be wrong but this is what I saw after trying to implement MapFragment & SupportMapFragment.

Setting up the layout for showing the map in the file location_fragment.xml:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <com.google.android.gms.maps.MapView
        android:id="@+id/mapView"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</RelativeLayout>

Now, we code the Java class for showing the map in the file MapViewFragment.java:

public class MapViewFragment extends Fragment {

    MapView mMapView;
    private GoogleMap googleMap;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.location_fragment, container, false);

        mMapView = (MapView) rootView.findViewById(R.id.mapView);
        mMapView.onCreate(savedInstanceState);

        mMapView.onResume(); // needed to get the map to display immediately

        try {
            MapsInitializer.initialize(getActivity().getApplicationContext());
        } catch (Exception e) {
            e.printStackTrace();
        }

        mMapView.getMapAsync(new OnMapReadyCallback() {
            @Override
            public void onMapReady(GoogleMap mMap) {
                googleMap = mMap;

                // For showing a move to my location button
                googleMap.setMyLocationEnabled(true);

                // For dropping a marker at a point on the Map
                LatLng sydney = new LatLng(-34, 151);
                googleMap.addMarker(new MarkerOptions().position(sydney).title("Marker Title").snippet("Marker Description"));

                // For zooming automatically to the location of the marker
                CameraPosition cameraPosition = new CameraPosition.Builder().target(sydney).zoom(12).build();
                googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));
            }
        });

        return rootView;
    }

    @Override
    public void onResume() {
        super.onResume();
        mMapView.onResume();
    }

    @Override
    public void onPause() {
        super.onPause();
        mMapView.onPause();
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        mMapView.onDestroy();
    }

    @Override
    public void onLowMemory() {
        super.onLowMemory();
        mMapView.onLowMemory();
    }
}

Finally you need to get the API Key for your app by registering your app at Google Cloud Console. Register your app as Native Android App.

You have to use code similar to this:

echo "<div id='divwithform'>";

if(isset($_POST['submit']))  // if form was submitted (if you came here with form data)
{
    echo "Success";
}
else                // if form was not submitted (if you came here without form data)
{
    echo "<form> ... </form>";
} 

echo "</div>";

Code with if like this is typical for many pages, however this is very simplified.

Normally, you have to validate some data in first "if" (check if form fields were not empty etc).

Please visit www.thenewboston.org or phpacademy.org. There are very good PHP video tutorials, including forms.

If you're instantiating an android.support.v4.app.Fragment class, the you have to call getActivity().getSupportFragmentManager() to get rid of the cannot-resolve problem. However the official Android docs on Fragment by Google tends to over look this simple problem and they still document it without the getActivity() prefix.

Code:

while True:
        n += 1
        try:
          DATA[n]['message']['text']
        except:
          key = DATA[n-1]['message']['text']
          break

Console :

Traceback (most recent call last):
  File "botnet.py", line 82, in <module>
    key =DATA[n-1]['message']['text']
IndexError: list index out of range

componentDidUpdate(){               
    $(".wpcf7-submit").click( function(event) {
        event.preventDefault();
    })
}

You can use componentDidUpdate and event.preventDefault() to disable form submission.As react does not support return false.

I had the same problem. Try this.

<nav>
    <ul>
        <li><a href="#">AnaSayfa</a></li>
        <li><a href="#">Hakkimizda</a></li>
        <li><a href="#">Iletisim</a></li>
    </ul>
</nav>

@charset "utf-8";

nav {
    background-color: #9900CC;
    height: 80px;
    width: 400px;
}

ul {
    list-style: none;
    float: right;
    margin: 0;
}

li {
    float: left;
    width: 100px;
    line-height: 80px;
    vertical-align: middle;
    text-align: center;
    margin: 0;
}

nav li a {
    width: 100px;
    text-decoration: none;
    color: #FFFFFF;
}

This is just my personal opinion and folks from web API team can probably articulate it better but here is my 2c.

First of all, I think it is not a question of one over another. You can use them both depending on what you want to do in your action method but in order to understand the real power of IHttpActionResult, you will probably need to step outside those convenient helper methods of ApiController such as Ok, NotFound, etc.

Basically, I think a class implementing IHttpActionResult as a factory of HttpResponseMessage. With that mind set, it now becomes an object that need to be returned and a factory that produces it. In general programming sense, you can create the object yourself in certain cases and in certain cases, you need a factory to do that. Same here.

If you want to return a response which needs to be constructed through a complex logic, say lots of response headers, etc, you can abstract all those logic into an action result class implementing IHttpActionResult and use it in multiple action methods to return response.

Another advantage of using IHttpActionResult as return type is that it makes ASP.NET Web API action method similar to MVC. You can return any action result without getting caught in media formatters.

Of course, as noted by Darrel, you can chain action results and create a powerful micro-pipeline similar to message handlers themselves in the API pipeline. This you will need depending on the complexity of your action method.

Long story short - it is not IHttpActionResult versus HttpResponseMessage. Basically, it is how you want to create the response. Do it yourself or through a factory.

while Alexey Kukanov's answer may be more efficient, you can also iterate through a queue in a very natural manner, by popping each element from the front of the queue, then pushing it to the back:

#include <iostream>
#include <queue>

using namespace std;

int main() {
    //populate queue
    queue<int> q;
    for (int i = 0; i < 10; ++i) q.push(i);

    // iterate through queue
    for (size_t i = 0; i < q.size(); ++i) {
        int elem = std::move(q.front());
        q.pop();
        elem *= elem;
        q.push(std::move(elem));
    }

    //print queue
    while (!q.empty()) {
        cout << q.front() << ' ';
        q.pop();
    }
}

output:

0 1 4 9 16 25 36 49 64 81 

replace method of string objects does not accept regular expressions but only fixed strings (see documentation: http://docs.python.org/2/library/stdtypes.html#str.replace).

You have to use re module:

import re
newline= re.sub("<\/?\[[0-9]+>", "", line)

I'd recommend using an HTML parser over a regex, but still here's a regex that will create a capturing group over the value of the href attribute of each links. It will match whether double or single quotes are used.

<a\s+(?:[^>]*?\s+)?href=(["'])(.*?)\1

You can view a full explanation of this regex at here.

Snippet playground:

const linkRx = /<a\s+(?:[^>]*?\s+)?href=(["'])(.*?)\1/;_x000D_
const textToMatchInput = document.querySelector('[name=textToMatch]');_x000D_
_x000D_
document.querySelector('button').addEventListener('click', () => {_x000D_
  console.log(textToMatchInput.value.match(linkRx));_x000D_
});

<label>_x000D_
  Text to match:_x000D_
  <input type="text" name="textToMatch" value='<a href="google.com"'>_x000D_
  _x000D_
  <button>Match</button>_x000D_
 </label>

In Ubuntu you can apply this way,

to save file at some location (temporary) and then open and send it to API

      path = default_storage.save('static/tmp/' + f1.name, ContentFile(f1.read()))
      path12 = os.path.join(os.getcwd(), "static/tmp/" + f1.name)
      data={} #can be anything u want to pass along with File
      file1 = open(path12, 'rb')
      header = {"Content-Disposition": "attachment; filename=" + f1.name, "Authorization": "JWT " + token}
       res= requests.post(url,data,header)

Use setItem and getItem if you want to write simple strings to localStorage. Also you should be using text() if it's the text you're after as you say, else you will get the full HTML as a string.

Sample using .text()

// get the text
var text = $('#test').text();

// set the item in localStorage
localStorage.setItem('test', text);

// alert the value to check if we got it
alert(localStorage.getItem('test'));

JSFiddle: https://jsfiddle.net/f3zLa3zc/

Storing the HTML itself

// get html
var html = $('#test')[0].outerHTML;

// set localstorage
localStorage.setItem('htmltest', html);

// test if it works
alert(localStorage.getItem('htmltest'));

JSFiddle:
https://jsfiddle.net/psfL82q3/1/

Update on user comment

A user want to update the localStorage when the div's content changes. Since it's unclear how the div contents changes (ajax, other method?) contenteditable and blur() is used to change the contents of the div and overwrite the old localStorage entry.

// get the text
var text = $('#test').text();

// set the item in localStorage
localStorage.setItem('test', text);

// bind text to 'blur' event for div
$('#test').on('blur', function() {

    // check the new text
    var newText = $(this).text();

    // overwrite the old text
    localStorage.setItem('test', newText);

    // test if it works
    alert(localStorage.getItem('test'));

});

If we were using ajax we would instead trigger the function it via the function responsible for updating the contents.

JSFiddle:
https://jsfiddle.net/g1b8m1fc/

As TokenMacGuy says, you should use thread.is_alive() to check if a thread is still running. To remove no longer running threads from your list you can use a list comprehension:

for t in my_threads:
    if not t.is_alive():
        # get results from thread
        t.handled = True
my_threads = [t for t in my_threads if not t.handled]

This avoids the problem of removing items from a list while iterating over it.

Edited:

You should really be using openssl_encrypt() & openssl_decrypt()

As Scott says, Mcrypt is not a good idea as it has not been updated since 2007.

There is even an RFC to remove Mcrypt from PHP - https://wiki.php.net/rfc/mcrypt-viking-funeral

I was having some difficulty translating actual VB.NET to the Expression subset that SSRS uses. You definitely inspired me though and this is what I came up with.

StartDate  
=dateadd("d",0,dateserial(year(dateadd("d",-1,dateserial(year(Today),month(Today),1))),month(dateadd("d",-1,dateserial(year(Today),month(Today),1))),1))

End Date
=dateadd("d",0,dateserial(year(Today),month(Today),1))  

I know it's a bit recursive for the StartDate (first day of last month). Is there anything I'm missing here? These are strictly date fields (i.e. no time), but I think this should capture leap year, etc.

How did I do?

Use cell magic and this project on github by Phillip Cloud:

Load it by putting this at the top of your notebook or put it in your config file if you always want to load it by default:

%install_ext https://raw.github.com/cpcloud/ipython-autotime/master/autotime.py
%load_ext autotime

If loaded, every output of subsequent cell execution will include the time in min and sec it took to execute it.

you need to wrap your text inside div and float it left while wrapper div should have height, and I've also added line height for vertical alignment

<div style="border-bottom-width: 1px; border-bottom-style: solid; border-bottom-color: gray;height:30px;">
   <div style="float:left;line-height:30px;">Contact Details</div>

    <button type="button" class="edit_button" style="float: right;">My Button</button>

</div>

Easiest way to do is :

awk 'NR==FNR{a[$1]++;next} a[$1] ' file1 file2

Files are not necessary to be sorted.

I use this:

logging.conf:

[loggers]
keys=root,applog
[handlers]
keys=rotateFileHandler,rotateConsoleHandler

[formatters]
keys=applog_format,console_format

[formatter_applog_format]
format=%(asctime)s-[%(levelname)-8s]:%(message)s

[formatter_console_format]
format=%(asctime)s-%(filename)s%(lineno)d[%(levelname)s]:%(message)s

[logger_root]
level=DEBUG
handlers=rotateFileHandler,rotateConsoleHandler

[logger_applog]
level=DEBUG
handlers=rotateFileHandler
qualname=simple_example

[handler_rotateFileHandler]
class=handlers.RotatingFileHandler
level=DEBUG
formatter=applog_format
args=('applog.log', 'a', 10000, 9)

[handler_rotateConsoleHandler]
class=StreamHandler
level=DEBUG
formatter=console_format
args=(sys.stdout,)

testapp.py:

import logging
import logging.config

def main():
    logging.config.fileConfig('logging.conf')
    logger = logging.getLogger('applog')

    logger.debug('debug message')
    logger.info('info message')
    logger.warn('warn message')
    logger.error('error message')
    logger.critical('critical message')
    #logging.shutdown()

if __name__ == '__main__':
    main()

They are not managed, but measured and possibly limited (see getrlimit system call, also on getrlimit(2)).

RSS means resident set size (the part of your virtual address space sitting in RAM).

You can query the virtual address space of process 1234 using proc(5) with cat /proc/1234/maps and its status (including memory consumption) thru cat /proc/1234/status

setTimout executes outside of angular. You need to use $timeout service for this to work:

var app = angular.module('test', []);

    app.controller('TestCtrl', function ($scope, $timeout) {
       $scope.testValue = 0;

        $timeout(function() {
            console.log($scope.testValue++);
        }, 500);
    });

The reason is that two-way binding in angular uses dirty checking. This is a good article to read about angular's dirty checking. $scope.$apply() kicks off a $digest cycle. This will apply the binding. $timeout handles the $apply for you so it is the recommended service to use when using timeouts.

Essentially, binding happens during the $digest cycle (if the value is seen to be different).

The IIFE simply compartmentalizes the function and hides the msg variable so as to not "pollute" the global namespace. In reality, just keep it simple and do like below unless you are building a billion dollar website.

var msg = "later dude";
window.onunload = function(msg){
  alert( msg );
};

You could namespace your msg property using a Revealing Module Pattern like:

var myScript = (function() {
    var pub = {};
    //myscript.msg
    pub.msg = "later dude";
    window.onunload = function(msg) {
        alert(msg);
    };
    //API
    return pub;
}());

On Xampp edit apache config

1. Click Apache 'config'
2. Select 'httpd-ssl.conf'
3. Look for 'Listen 443', change it to 'Listen 4430'

I ended up finding git attributes. Trying it. Working so far. Did not check all scenarios yet. But it should be the solution.

Merge Strategies - Git attributes

swift 3

if let url = URL(string: "fb://profile/<id>") {
        if #available(iOS 10, *) {
            UIApplication.shared.open(url, options: [:],completionHandler: { (success) in
                print("Open fb://profile/<id>: \(success)")
            })
        } else {
            let success = UIApplication.shared.openURL(url)
            print("Open fb://profile/<id>: \(success)")
        }
 }

Here is my solution:

<td>
   <a href="/yourURL"></a>
   <div class="item-container">
      <img class="icon" src="/iconURL" />
      <p class="name">
         SomeText
      </p>
   </div>
</td>

(LESS)

td {
  padding: 1%;
  vertical-align: bottom;
  position:relative;

     a {
        height: 100%;
        display: block;
        position: absolute;
        top:0;
        bottom:0;
        right:0;
        left:0;
       }

     .item-container {
         /*...*/
     }
}

Like this you can still benefit from some table cell properties like vertical-align.(Tested on Chrome)

I think your code is trying to "divide by zero" or "divide by NaN". If you are aware of that and don't want it to bother you, then you can try:

import numpy as np
np.seterr(divide='ignore', invalid='ignore')

For more details see:

• http://docs.scipy.org/doc/numpy/reference/generated/numpy.seterr.html

You can use the ansible.cfg file, it should look like this (There are other parameters which you might want to include):

[defaults]
inventory = <PATH TO INVENTORY FILE>
remote_user = <YOUR USER>
private_key_file =  <PATH TO KEY_FILE>

Hope this saves you some typing

Using Integer.parseIn(String), you can parse string value into integer. Also you need to catch exception in case if input string is not a proper number.

int x = 0;

try {       
    x = Integer.parseInt("100"); // Parse string into number
} catch (NumberFormatException e) {
    e.printStackTrace();
}

Use the string objects Match method:

// Match a string that ends with abc, similar to LIKE '%abc'
if (theString.match(/^.*abc$/)) 
{ 
    /*Match found */
}

// Match a string that starts with abc, similar to LIKE 'abc%'
if (theString.match(/^abc.*$/)) 
{ 
    /*Match found */
}

Try this:

private string GetJArrayValue(JObject yourJArray, string key)
{
    foreach (KeyValuePair<string, JToken> keyValuePair in yourJArray)
    {
        if (key == keyValuePair.Key)
        {
            return keyValuePair.Value.ToString();
        }
    }
}

Using CodeIgniter OAuth2/0.4.0 sparks,

in Auth.php file,

$user = $provider->get_user_info($token);

$friends = $provider->get_friends_list($token);
print_r($friends);

and in Facebook.php file under Provider, add the following function,

    public function get_friends_list(OAuth2_Token_Access $token)
    {
            $url = 'https://graph.facebook.com/me/friends?'.http_build_query(array(

            $friends = json_decode(file_get_contents($url),TRUE);

            return $friends;
    }

prints the facebenter code hereook friends.

The message means that both the packages have functions with the same names. In this particular case, the testthat and assertive packages contain five functions with the same name.

When two functions have the same name, which one gets called?

R will look through the search path to find functions, and will use the first one that it finds.

search()
 ##  [1] ".GlobalEnv"        "package:assertive" "package:testthat" 
 ##  [4] "tools:rstudio"     "package:stats"     "package:graphics" 
 ##  [7] "package:grDevices" "package:utils"     "package:datasets" 
 ## [10] "package:methods"   "Autoloads"         "package:base"

In this case, since assertive was loaded after testthat, it appears earlier in the search path, so the functions in that package will be used.

is_true
## function (x, .xname = get_name_in_parent(x)) 
## {
##     x <- coerce_to(x, "logical", .xname)
##     call_and_name(function(x) {
##         ok <- x & !is.na(x)
##         set_cause(ok, ifelse(is.na(x), "missing", "false"))
##     }, x)
## }
<bytecode: 0x0000000004fc9f10>
<environment: namespace:assertive.base>

The functions in testthat are not accessible in the usual way; that is, they have been masked.

What if I want to use one of the masked functions?

You can explicitly provide a package name when you call a function, using the double colon operator, ::. For example:

testthat::is_true
## function () 
## {
##     function(x) expect_true(x)
## }
## <environment: namespace:testthat>

How do I suppress the message?

If you know about the function name clash, and don't want to see it again, you can suppress the message by passing warn.conflicts = FALSE to library.

library(testthat)
library(assertive, warn.conflicts = FALSE)
# No output this time

Alternatively, suppress the message with suppressPackageStartupMessages:

library(testthat)
suppressPackageStartupMessages(library(assertive))
# Also no output

Impact of R's Startup Procedures on Function Masking

If you have altered some of R's startup configuration options (see ?Startup) you may experience different function masking behavior than you might expect. The precise order that things happen as laid out in ?Startup should solve most mysteries.

For example, the documentation there says:

Note that when the site and user profile files are sourced only the base package is loaded, so objects in other packages need to be referred to by e.g. utils::dump.frames or after explicitly loading the package concerned.

Which implies that when 3rd party packages are loaded via files like .Rprofile you may see functions from those packages masked by those in default packages like stats, rather than the reverse, if you loaded the 3rd party package after R's startup procedure is complete.

How do I list all the masked functions?

First, get a character vector of all the environments on the search path. For convenience, we'll name each element of this vector with its own value.

library(dplyr)
envs <- search() %>% setNames(., .)

For each environment, get the exported functions (and other variables).

fns <- lapply(envs, ls)

Turn this into a data frame, for easy use with dplyr.

fns_by_env <- data_frame(
  env = rep.int(names(fns), lengths(fns)),
  fn  = unlist(fns)
)

Find cases where the object appears more than once.

fns_by_env %>% 
  group_by(fn) %>% 
  tally() %>% 
  filter(n > 1) %>% 
  inner_join(fns_by_env)

To test this, try loading some packages with known conflicts (e.g., Hmisc, AnnotationDbi).

How do I prevent name conflict bugs?

The conflicted package throws an error with a helpful error message, whenever you try to use a variable with an ambiguous name.

library(conflicted)
library(Hmisc)
units
## Error: units found in 2 packages. You must indicate which one you want with ::
##  * Hmisc::units
##  * base::units

    file = open("path/of/file/(optional)/filename.txt", "w") #a=append,w=write,r=read
    any_string = "Hello\nWorld"
    file.write(any_string)
    file.close()

Yes:

RelativeLayout.LayoutParams params= new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT); 
params.addRule(RelativeLayout.BELOW, R.id.below_id);
viewToLayout.setLayoutParams(params);

First, the code creates a new layout params by specifying the height and width. The addRule method adds the equivalent of the xml properly android:layout_below. Then you just call View#setLayoutParams on the view you want to have those params.

Resurrecting the dead here, but just in case someone stumbles against this like myself. I know where to get the maximum value of a double, the (more) interesting part was to how did they get to that number.

double has 64 bits. The first one is reserved for the sign.

Next 11 represent the exponent (that is 1023 biased). It's just another way to represent the positive/negative values. If there are 11 bits then the max value is 1023.

Then there are 52 bits that hold the mantissa.

This is easily computed like this for example:

public static void main(String[] args) {

    String test = Strings.repeat("1", 52);

    double first = 0.5;
    double result = 0.0;
    for (char c : test.toCharArray()) {
        result += first;
        first = first / 2;
    }

    System.out.println(result); // close approximation of 1
    System.out.println(Math.pow(2, 1023) * (1 + result));
    System.out.println(Double.MAX_VALUE);

} 

You can also prove this in reverse order :

    String max = "0" + Long.toBinaryString(Double.doubleToLongBits(Double.MAX_VALUE));

    String sign = max.substring(0, 1);
    String exponent = max.substring(1, 12); // 11111111110
    String mantissa = max.substring(12, 64);

    System.out.println(sign); // 0 - positive
    System.out.println(exponent); // 2046 - 1023 = 1023
    System.out.println(mantissa); // 0.99999...8

REST is stateless and doesn’t maintain any states between the requests. Client cookies / headers are set to maintain the user state like authentication. Say Client username/password are validated by third part authentication mechanism – 2nd level OTP gerneation etc. Once user get authenticated – headers /cookies comes to rest service end point exposed and we can assume user as auth since user is coming with valid headers/cookies. Now certain info of user like IP is either maintained in the cache and after that if request is coming from same Ip (mac address) for listed resources User is allowed. And cache is maintained for some particular time which get invalidated once time lapses. So either cache can be used or DB entries can be used to persist info b/w the requests.

1. you have to have a reference to the form object in order to access its elements
2. the elements have to be declared public in order for another class to access them
3. don't do this - your class has to know too much about how your form is implemented; do not expose form controls outside of the form class
4. instead, make public properties on your form to get/set the values you are interested in
5. post more details of what you want and why, it sounds like you may be heading off in a direction that is not consistent with good encapsulation practices

in your setChilds, you might want to try looping thru the list and doing something like

child.parent = this;

you also should set up the cascade on the parent to the appropriate values.

You can get the ROWID by using the methods given below :

1.Create a new table with auto increment field in it

2.Use Row_Number analytical function to get the sequence based on your requirement.I would prefer this because it helps in situations where you are you want the row_id on ascending or descending manner of a specific field or combination of fields

Sample:Row_Number() Over(Partition by Deptno order by sal desc)

Above sample will give you the sequence number based on highest salary of each department.Partition by is optional and you can remove it according to your requirements

There is HTML and URI encodings. & is & encoded in HTML while %26 is & in URI encoding.

So before URI encoding your string you might want to HTML decode and then URI encode it :)

var div = document.createElement('div');
div.innerHTML = '&AndOtherHTMLEncodedStuff';
var htmlDecoded = div.firstChild.nodeValue;
var urlEncoded = encodeURIComponent(htmlDecoded);

result %26AndOtherHTMLEncodedStuff

Hope this saves you some time

The Problem

In MySQL, certain words like SELECT, INSERT, DELETE etc. are reserved words. Since they have a special meaning, MySQL treats it as a syntax error whenever you use them as a table name, column name, or other kind of identifier - unless you surround the identifier with backticks.

As noted in the official docs, in section 10.2 Schema Object Names (emphasis added):

Certain objects within MySQL, including database, table, index, column, alias, view, stored procedure, partition, tablespace, and other object names are known as identifiers.

...

If an identifier contains special characters or is a reserved word, you must quote it whenever you refer to it.

...

The identifier quote character is the backtick ("`"):

A complete list of keywords and reserved words can be found in section 10.3 Keywords and Reserved Words. In that page, words followed by "(R)" are reserved words. Some reserved words are listed below, including many that tend to cause this issue.

• ADD
• AND
• BEFORE
• BY
• CALL
• CASE
• CONDITION
• DELETE
• DESC
• DESCRIBE
• FROM
• GROUP
• IN
• INDEX
• INSERT
• INTERVAL
• IS
• KEY
• LIKE
• LIMIT
• LONG
• MATCH
• NOT
• OPTION
• OR
• ORDER
• PARTITION
• RANK
• REFERENCES
• SELECT
• TABLE
• TO
• UPDATE
• WHERE

The Solution

You have two options.

1. Don't use reserved words as identifiers

The simplest solution is simply to avoid using reserved words as identifiers. You can probably find another reasonable name for your column that is not a reserved word.

Doing this has a couple of advantages:

• It eliminates the possibility that you or another developer using your database will accidentally write a syntax error due to forgetting - or not knowing - that a particular identifier is a reserved word. There are many reserved words in MySQL and most developers are unlikely to know all of them. By not using these words in the first place, you avoid leaving traps for yourself or future developers.

• The means of quoting identifiers differs between SQL dialects. While MySQL uses backticks for quoting identifiers by default, ANSI-compliant SQL (and indeed MySQL in ANSI SQL mode, as noted here) uses double quotes for quoting identifiers. As such, queries that quote identifiers with backticks are less easily portable to other SQL dialects.

Purely for the sake of reducing the risk of future mistakes, this is usually a wiser course of action than backtick-quoting the identifier.

2. Use backticks

If renaming the table or column isn't possible, wrap the offending identifier in backticks (`) as described in the earlier quote from 10.2 Schema Object Names.

An example to demonstrate the usage (taken from 10.3 Keywords and Reserved Words):

mysql> CREATE TABLE interval (begin INT, end INT);
ERROR 1064 (42000): You have an error in your SQL syntax.
near 'interval (begin INT, end INT)'
mysql> CREATE TABLE `interval` (begin INT, end INT);
Query OK, 0 rows affected (0.01 sec)

Similarly, the query from the question can be fixed by wrapping the keyword key in backticks, as shown below:

INSERT INTO user_details (username, location, `key`)
VALUES ('Tim', 'Florida', 42)";               ^   ^

Compile with O3, The compiler performs optimization well.

q = x / y;
if (x % y)  ++q;

Putting it all together:

• REGEX doesn't validate values (like "2010-19-19")
• SimpleDateFormat does not check format ("2010-1-2", "1-0002-003" are accepted)

it's necessary to use both to validate format and value:

public static boolean isValid(String text) {
    if (text == null || !text.matches("\\d{4}-[01]\\d-[0-3]\\d"))
        return false;
    SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd");
    df.setLenient(false);
    try {
        df.parse(text);
        return true;
    } catch (ParseException ex) {
        return false;
    }
}

private static final ThreadLocal<SimpleDateFormat> format = new ThreadLocal<SimpleDateFormat>() {
    @Override
    protected SimpleDateFormat initialValue() {
        SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd");
        df.setLenient(false);
        System.out.println("created");
        return df;
    }
};

public static boolean isValid(String text) {
    if (text == null || !text.matches("\\d{4}-[01]\\d-[0-3]\\d"))
        return false;
    try {
        format.get().parse(text);
        return true;
    } catch (ParseException ex) {
        return false;
    }
}

(same can be done for a Matcher, that also is not thread safe)
