With the adoption of CoreSimulator in Xcode 6.0, the data directories are per-device rather than per-version. The data directory is ~/Library/Developer/CoreSimulator/Devices//data where can be determined from 'xcrun simctl list'

Note that you can safely delete ~/Library/Application Support/iPhone Simulator and ~/Library/Logs/iOS Simulator if you don't plan on needing to roll back to Xcode 5.x or earlier.

Simple code for replace all spaces

var str = 'How are you';
var replaced = str.split(' ').join('');

Out put: Howareyou

The following code will split a string with an arbitrary number of substrings:

@echo off
setlocal ENABLEDELAYEDEXPANSION

REM Set a string with an arbitrary number of substrings separated by semi colons
set teststring=The;rain;in;spain

REM Do something with each substring
:stringLOOP
    REM Stop when the string is empty
    if "!teststring!" EQU "" goto END

    for /f "delims=;" %%a in ("!teststring!") do set substring=%%a

        REM Do something with the substring - 
        REM we just echo it for the purposes of demo
        echo !substring!

REM Now strip off the leading substring
:striploop
    set stripchar=!teststring:~0,1!
    set teststring=!teststring:~1!

    if "!teststring!" EQU "" goto stringloop

    if "!stripchar!" NEQ ";" goto striploop

    goto stringloop
)

:END
endlocal

Here is a slightly concised edition of what Jason suggested:

DateTime? d; DateTime dt;
d = DateTime.TryParse(DateTime.Now.ToString(), out dt)? dt : (DateTime?)null;

In response to: "How to convert Tue Sep 13 2016 00:00:00 GMT-0500 (Hora de verano central (México)) to dd-MM-yy in Java?", it was marked how duplicate

Try this: With java.util.Date, java.text.SimpleDateFormat, it's a simple solution.

public static void main(String[] args) throws ParseException {

    String fecha = "Tue Sep 13 2016 00:00:00 GMT-0500 (Hora de verano central (México))";
    Date f = new Date(fecha);

    SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
    sdf.setTimeZone(TimeZone.getTimeZone("-5GMT"));
    fecha = sdf.format(f);
    System.out.println(fecha);
}

 var params= new Dictionary<string, string>();
 var url ="Please enter URLhere";

I solved the problem by enabling the TCP/IP using the SQL Server Configuration Manager under Protocols for SQLEXPRESS2008, i restarted the service and now the "Server is listening on" shows up in the ERRORLOG file

I was dealing with this issue after upgrading from Visual Studio 2013 to Visual Studio 2015 After trying most of the advice found in this and other similar SO posts, I finally found the problem. The first part of the fix was to update all of my NuGet stuff to the latest version (you might need to do this in VS13 if you are experiencing the Nuget bug) after, I had to, as you may need to, fix the versions listed in the Views Web.config. This includes:

1. Fix MVC versions and its child libraries to the new version (expand the References then right click onSytem.Web.MVC then Properties to get your version)
2. Fix the Razor version.

Mine looked like this:

Mac OSX 10.7.5: I tried setting my proxy in the settings.xml file (as mentioned by posters above) in the /conf directory and also in the ~/.m2 directory, but still I got this error. I downloaded the latest version of Maven (3.1.1), and set my PATH variable to reflect the latest install, and it worked for me right off the shelf without any error.

After many years of database development I can say there are some no goes and some question that you should answer before you begin:

questions:

• Do you want use in the future another DBMS? If yes then does not use to special SQL stuff of the current DBMS. Remove logic in your application.

Does not use:

• white spaces in table names and column names
• Non Ascii characters in table and column names
• binding to a specific lower case or upper case. And never use 2 tables or columns that differ only with lower case and upper case.
• does not use SQL keywords for tables or columns names like "FROM", "BETWEEN", "DELETE", etc

recomendations:

• Use NVARCHAR or equivalents for unicode support then you have no problems with codepages.
• Give every column a unique name. This make it easer on join to select the column. It is very difficult if every table has a column "ID" or "Name" or "Description". Use XyzID and AbcID.
• Use a resource bundle or equals for complex SQL expressions. It make it easer to switch to another DBMS.
• Does not cast hard on any data type. Another DBMS can not have this data type. FOr example Oracle daes not have a SMALLINT only a number.

I hope this is a good starting point.

I use this pattern fairly frequently - I've found that it gives me a pretty huge amount of flexibility when I need it. In use it's rather similar to Java-style classes.

var Foo = function()
{

    var privateStaticMethod = function() {};
    var privateStaticVariable = "foo";

    var constructor = function Foo(foo, bar)
    {
        var privateMethod = function() {};
        this.publicMethod = function() {};
    };

    constructor.publicStaticMethod = function() {};

    return constructor;
}();

This uses an anonymous function that is called upon creation, returning a new constructor function. Because the anonymous function is called only once, you can create private static variables in it (they're inside the closure, visible to the other members of the class). The constructor function is basically a standard Javascript object - you define private attributes inside of it, and public attributes are attached to the this variable.

Basically, this approach combines the Crockfordian approach with standard Javascript objects to create a more powerful class.

You can use it just like you would any other Javascript object:

Foo.publicStaticMethod(); //calling a static method
var test = new Foo();     //instantiation
test.publicMethod();      //calling a method

One can use the Shuffle extension methond from morelinq package, it works on IEnumerables

install-package morelinq

using MoreLinq;
...    
var randomized = list.Shuffle();

Swift 3.0 to 5.0 Updated Solution:

//MARK:- Validation Extension -

extension String {

    //To check text field or String is blank or not
    var isBlank: Bool {
        get {
            let trimmed = trimmingCharacters(in: CharacterSet.whitespaces)
            return trimmed.isEmpty
        }
    }

    //Validate Email

    var isEmail: Bool {
        do {
            let regex = try NSRegularExpression(pattern: "[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,}", options: .caseInsensitive)
            return regex.firstMatch(in: self, options: NSRegularExpression.MatchingOptions(rawValue: 0), range: NSMakeRange(0, self.count)) != nil
        } catch {
            return false
        }
    }

    var isAlphanumeric: Bool {
        return !isEmpty && range(of: "[^a-zA-Z0-9]", options: .regularExpression) == nil

                if(self.characters.count>=6 && self.count<=20){
                    return true
                }else{
                    return false

            }
        } catch {
            return false
        }
    }
}

use of Email Validation:

if(txtEmail.isEmail){
}

Swift 2.0 Solution

Paste these line anywhere in code.(or in your Constant file)

extension String {

    //To check text field or String is blank or not
    var isBlank: Bool {
        get {
            let trimmed = stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceCharacterSet())
            return trimmed.isEmpty
        }
    }

    //Validate Email
    var isEmail: Bool {
        do {
            let regex = try NSRegularExpression(pattern: "[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,}", options: .CaseInsensitive)
            return regex.firstMatchInString(self, options: NSMatchingOptions(rawValue: 0), range: NSMakeRange(0, self.count)) != nil
        } catch {
            return false
        }
    }

    //validate PhoneNumber
    var isPhoneNumber: Bool {

        let charcter  = NSCharacterSet(charactersInString: "+0123456789").invertedSet
        var filtered:NSString!
        let inputString:NSArray = self.componentsSeparatedByCharactersInSet(charcter)
        filtered = inputString.componentsJoinedByString("")
        return  self == filtered

    }
}

I faced the same problem. Renaming the file worked for me.

As @borayeris said,

yum install glibc.i686

But if you cannot find glibc.i686 or libstdc++ package, try -

sudo yum search glibc
sudo yum search libstd

and then,

sudo yum install {package}

The method is to use another byte along with a bitwise AND to mask out the target bit.

I used convention from my classes here where "0" is the most significant bit and "7" is the least.

public static class ByteExtensions
{
    // Assume 0 is the MSB andd 7 is the LSB.
    public static bool GetBit(this byte byt, int index)
    {
        if (index < 0 || index > 7)
            throw new ArgumentOutOfRangeException();

        int shift = 7 - index;

        // Get a single bit in the proper position.
        byte bitMask = (byte)(1 << shift);

        // Mask out the appropriate bit.
        byte masked = (byte)(byt & bitMask);

        // If masked != 0, then the masked out bit is 1.
        // Otherwise, masked will be 0.
        return masked != 0;
    }
}

You need to stringify the json, not calling toString

var buf = Buffer.from(JSON.stringify(obj));

And for converting string to json obj :

var temp = JSON.parse(buf.toString());

Have a look at Boost.Phoenix for polymorphic lambdas: http://www.boost.org/doc/libs/1_44_0/libs/spirit/phoenix/doc/html/index.html Does not require C++0x, by the way :)

http://docs.oracle.com/javase/7/docs/api/javax/swing/JTable.html

You will find these methods in it:

getValueAt(int row, int column)
getSelectedRow()
getSelectedColumn()

Use a mix of these to achieve your result.

You can use this code(Recommended)

 MemoryStream objMS = new MemoryStream();
 DataTable oDT = new DataTable();//Your DataTable which you want to convert
 oDT.WriteXml(objMS);
 objMS.Position = 0;
 XPathDocument result = new XPathDocument(objMS);

This is another way but first ex. is recommended

StringWriter objSW = new StringWriter();
DataTable oDt = new DataTable();//Your DataTable which you want to convert
oDt.WriteXml(objSW);
string result = objSW.ToString();

One can also nullify parent's line height:

#wrapper {
  line-height: 0;
}

Well this is not listed but a combo of some that is already posted:

if (Build.VERSION.SDK_INT >= 11) {
    recreate();   
} else {
    Intent intent = getIntent();
    finish();
    startActivity(intent);
}

What is the __main__.py file for?

When creating a Python module, it is common to make the module execute some functionality (usually contained in a main function) when run as the entry point of the program. This is typically done with the following common idiom placed at the bottom of most Python files:

if __name__ == '__main__':
    # execute only if run as the entry point into the program
    main()

You can get the same semantics for a Python package with __main__.py, which might have the following structure:

.
+-- demo
    +-- __init__.py
    +-- __main__.py

To see this, paste the below into a Python 3 shell:

from pathlib import Path

demo = Path.cwd() / 'demo'
demo.mkdir()

(demo / '__init__.py').write_text("""
print('demo/__init__.py executed')

def main():
    print('main() executed')
""")

(demo / '__main__.py').write_text("""
print('demo/__main__.py executed')

from demo import main

main()
""")

We can treat demo as a package and actually import it, which executes the top-level code in the __init__.py (but not the main function):

>>> import demo
demo/__init__.py executed

When we use the package as the entry point to the program, we perform the code in the __main__.py, which imports the __init__.py first:

$ python -m demo
demo/__init__.py executed
demo/__main__.py executed
main() executed

You can derive this from the documentation. The documentation says:

__main__ — Top-level script environment

'__main__' is the name of the scope in which top-level code executes. A module’s __name__ is set equal to '__main__' when read from standard input, a script, or from an interactive prompt.

A module can discover whether or not it is running in the main scope by checking its own __name__, which allows a common idiom for conditionally executing code in a module when it is run as a script or with python -m but not when it is imported:

if __name__ == '__main__':
     # execute only if run as a script
     main()

For a package, the same effect can be achieved by including a __main__.py module, the contents of which will be executed when the module is run with -m.

Zipped

You can also zip up this directory, including the __main__.py, into a single file and run it from the command line like this - but note that zipped packages can't execute sub-packages or submodules as the entry point:

from pathlib import Path

demo = Path.cwd() / 'demo2'
demo.mkdir()

(demo / '__init__.py').write_text("""
print('demo2/__init__.py executed')

def main():
    print('main() executed')
""")

(demo / '__main__.py').write_text("""
print('demo2/__main__.py executed')

from __init__ import main

main()
""")

Note the subtle change - we are importing main from __init__ instead of demo2 - this zipped directory is not being treated as a package, but as a directory of scripts. So it must be used without the -m flag.

Particularly relevant to the question - zipapp causes the zipped directory to execute the __main__.py by default - and it is executed first, before __init__.py:

$ python -m zipapp demo2 -o demo2zip
$ python demo2zip
demo2/__main__.py executed
demo2/__init__.py executed
main() executed

Note again, this zipped directory is not a package - you cannot import it either.

Dividing the app into blueprints is a great idea. However, if this isn't enough, and if you want to then divide the Blueprint itself into multiple py files, this is also possible using the regular Python module import system, and then looping through all the routes that get imported from the other files.

I created a Gist with the code for doing this:

https://gist.github.com/Jaza/61f879f577bc9d06029e

As far as I'm aware, this is the only feasible way to divide up a Blueprint at the moment. It's not possible to create "sub-blueprints" in Flask, although there's an issue open with a lot of discussion about this:

https://github.com/mitsuhiko/flask/issues/593

Also, even if it were possible (and it's probably do-able using some of the snippets from that issue thread), sub-blueprints may be too restrictive for your use case anyway - e.g. if you don't want all the routes in a sub-module to have the same URL sub-prefix.

If using maven, just add to your pom.xml:

<dependency>
    <groupId>javax.mail</groupId>
    <artifactId>mail</artifactId>
    <version>1.5.0-b01</version>
</dependency>

Of course, you need to check the current version.

If you have a process that already generates and returns an Image type, you can alter the bind and not have to modify any additional image creation code.

Refer to the ".Source" of the image in the binding statement.

XAML

<Image Name="imgOpenClose" Source="{Binding ImageOpenClose.Source}"/>

View Model Field

private Image _imageOpenClose;
public Image ImageOpenClose
{
    get
    {
        return _imageOpenClose;
    }
    set
    {
        _imageOpenClose = value;
        OnPropertyChanged();
    }
}

Aside from tchrists excellent post concerning unicode, I think you don't need the complex solution with a negative lookahead... Your definition requires an Uppercase-letter followed by at least one group of (a lowercase letter optionally followed by an Uppercase-letter)

^
[A-Z]    // Start with an uppercase Letter
(        // A Group of:
  [a-z]  // mandatory lowercase letter
  [A-Z]? // an optional Uppercase Letter at the end
         // or in between lowercase letters
)+       // This group at least one time
$

Just a bit more compact and easier to read I think...

File myFile=new File("/tmp/myfile");
URL myUrl = myFile.toURI().toURL();

echo '<pre>' . htmlspecialchars("<div><b>raw HTML</b></div>") . '</pre>';

I think that's what you're looking for?

In other words, use htmlspecialchars() in PHP

This is a very old question, but I found a really simple way to do this:

authorsList = authorsList.Except(authors).ToList();

Note that since the return variable authorsList is a List<T>, the IEnumerable<T> returned by Except() must be converted to a List<T>.

class Test {
    public function yo() {
        return 'yoes';
    }
}

$var = 'Test';

$obj = new $var();
echo $obj->yo(); //yoes

Using the DateTime class available in PHP version 5.2 it would be done like this:

$datetime = new DateTime('17 Oct 2008');
echo $datetime->format('c');

See it in action

As of PHP 5.4 you can do this as a one-liner:

echo (new DateTime('17 Oct 2008'))->format('c');

// from http://wezfurlong.org/blog/2006/nov/http-post-from-php-without-curl
function do_post_request($url, $data, $optional_headers = null)
{
  $params = array('http' => array(
              'method' => 'POST',
              'content' => $data
            ));
  if ($optional_headers !== null) {
    $params['http']['header'] = $optional_headers;
  }
  $ctx = stream_context_create($params);
  $fp = @fopen($url, 'rb', false, $ctx);
  if (!$fp) {
    throw new Exception("Problem with $url, $php_errormsg");
  }
  $response = @stream_get_contents($fp);
  if ($response === false) {
    throw new Exception("Problem reading data from $url, $php_errormsg");
  }
  return $response;
}

I really appreciate @raykrow's answer when one has this problem only in a test file! That is where I encountered it.

As it is often helpful to have another way to do something as a backup, I wanted to mention this technique that also works (instead of importing RouterTestingModule):

import { MockComponent } from 'ng2-mock-component';
. . .
TestBed.configureTestingModule({
  declarations: [
    MockComponent({
      selector: 'a',
      inputs: [ 'routerLink', 'routerLinkActiveOptions' ]
    }),
    . . .
  ]

(Typically, one would use routerLink on an <a> element but adjust the selector accordingly for other components.)

The second reason I wanted to mention this alternate solution is that, though it served me well in a number of spec files, I ran into a problem with it in one case:

Error: Template parse errors:
    More than one component matched on this element.
    Make sure that only one component's selector can match a given element.
    Conflicting components: ButtonComponent,Mock

I could not quite figure out how this mock and my ButtonComponent were using the same selector, so searching for an alternate approach led me here to @raykrow's solution.

You said you copied files from another computer. After you copied them, did you 'Unblock' them? Specifically the .snk file should be checked to make sure it is not marked as unsafe.

There are free, easy APIs you can use, like those:

• http://ipinfodb.com/ip_location_api.php
• http://www.ipgeo.com/api/
• http://ip2.cc/
• http://www.geobytes.com/IpLocator.htm
• https://iplocate.io/
• and plenty others.

Which one looks the most trustworthy is up to you :)

Otherwise, there are scripts which are based on local databases on your server. The database data needs to be updated regularly, though. Check out this one:

• http://phpweby.com/software/ip2country

HTH!

Edit: And of course, depending on your project you might want to look at HTML5 Location features. You can't use them yet on the Internet Explorer (IE9 will support it, long way to go yet), but in case your audience is mainly on mobile devices or using Safari/Firefox it's definitely worth to look at it!

Once you have the coordinates, you can reverse geocode them to a country code. Again there are APIs like this one:

• Example: http://ws.geonames.org/countryCode?lat=47.03&lng=10.2
• More APIs: http://www.geonames.org/export/ws-overview.html

Update, April 2013
Today I would recommend using Geocoder, a PHP library which makes it very easy to geocode ip addresses as well as postal address data.

***Update, September 2016
Since Google's privacy politics has changed, you can't use HTML5 Geolocation API if your server doesn't have HTPPS certificate or user doesn't allow you check his location. So now you can use user's IP and check in in PHP or get HTTPS certificate.

As I could understand the question is not about how pass a string with control symbols using json but how to store and restore json in file where you can split a string with editor control symbols.

If you want to store multiline string in a file then your file will not store the valid json object. But if you use your json files in your program only, then you can store the data as you wanted and remove all newlines from file manually each time you load it to your program and then pass to json parser.

Or, alternatively, which would be better, you can have your json data source files where you edit a sting as you want and then remove all new lines with some utility to the valid json file which your program will use.

Ammending as "optional Answer". If you don't need to programmatically solve the problem, here goes the "visual way" in VS2012.

In Visual Studio, you can set custom format directly from the properties Panel:

First Set the "Format" property to: "Custom"; Secondly, set your custom format to: "dd-MM-yyyy";

First of all I'd like to say that I 100% agree with John Saunders that you must avoid loops in SQL in most cases especially in production.

But occasionally as a one time thing to populate a table with a hundred records for testing purposes IMHO it's just OK to indulge yourself to use a loop.

For example in your case to populate your table with records with hospital ids between 16 and 100 and make emails and descriptions distinct you could've used

CREATE PROCEDURE populateHospitals

DECLARE @hid INT;
SET @hid=16;
WHILE @hid < 100

The following snippet shows an example, which can archive a throughput of 400 MB/s while reading and hashing the file.

It is using a library called hash-wasm, which is based on WebAssembly and calculates the hash faster than js-only libraries. As of 2020, all modern browsers support WebAssembly.

const chunkSize = 64 * 1024 * 1024;
const fileReader = new FileReader();
let hasher = null;

function hashChunk(chunk) {
  return new Promise((resolve, reject) => {
    fileReader.onload = async(e) => {
      const view = new Uint8Array(e.target.result);
      hasher.update(view);
      resolve();
    };

    fileReader.readAsArrayBuffer(chunk);
  });
}

const readFile = async(file) => {
  if (hasher) {
    hasher.init();
  } else {
    hasher = await hashwasm.createMD5();
  }

  const chunkNumber = Math.floor(file.size / chunkSize);

  for (let i = 0; i <= chunkNumber; i++) {
    const chunk = file.slice(
      chunkSize * i,
      Math.min(chunkSize * (i + 1), file.size)
    );
    await hashChunk(chunk);
  }

  const hash = hasher.digest();
  return Promise.resolve(hash);
};

const fileSelector = document.getElementById("file-input");
const resultElement = document.getElementById("result");

fileSelector.addEventListener("change", async(event) => {
  const file = event.target.files[0];

  resultElement.innerHTML = "Loading...";
  const start = Date.now();
  const hash = await readFile(file);
  const end = Date.now();
  const duration = end - start;
  const fileSizeMB = file.size / 1024 / 1024;
  const throughput = fileSizeMB / (duration / 1000);
  resultElement.innerHTML = `
    Hash: ${hash}<br>
    Duration: ${duration} ms<br>
    Throughput: ${throughput.toFixed(2)} MB/s
  `;
});

Unfortunately, there is none. You can use the System.Collections.Generic.KeyValuePair<K, V> in many situations.

Alternatively, you can use anonymous types to handle tuples, at least locally:

var x = new { First = "x", Second = 42 };

The last alternative is to create an own class.

The most robust mechanism for listing all subclasses of a given class is currently ClassGraph, because it handles the widest possible array of classpath specification mechanisms, including the new JPMS module system. (I am the author.)

List<Class<Animal>> animals;
try (ScanResult scanResult = new ClassGraph().whitelistPackages("com.zoo.animals")
        .enableClassInfo().scan()) {
    animals = scanResult
        .getSubclasses(Animal.class.getName())
        .loadClasses(Animal.class);
}

If it's a matter of just opening PDF to send some keys to it then why not try this

Sub Sample()
    ActiveWorkbook.FollowHyperlink "C:\MyFile.pdf"
End Sub

I am assuming that you have some pdf reader installed.

If you're running into this issue despite trying all of the solutions in this thread, and you're connecting to the service via SSL (e.g. https), this might help:

http://forums.newatlanta.com/messages.cfm?threadid=554611A2-E03F-43DB-92F996F4B6222BC0&#top

To summarize (in case the link dies in the future), if your requests are large enough the certificate negotiation between the client and the service will fail randomly. To keep this from happening, you'll need to enable a certain setting on your SSL bindings. From your IIS server, here are the steps you'll need to take:

1. Via cmd or powershell, run netsh http show sslcert. This will give you your current configuration. You'll want to save this somehow so you can reference it again later.
2. You should notice that "Negotiate Client Certificate" is disabled. This is the problem setting; the following steps will demonstrate how to enable it.
3. Unfortunately there is no way to change existing bindings; you'll have to delete it and re-add it. Run netsh http delete sslcert <ipaddress>:<port> where <ipaddress>:<port> is the IP:port shown in the configuration you saved earlier.
4. Now you can re-add the binding. You can view the valid parameters for netsh http add sslcert here (MSDN) but in most cases your command will look like this:

netsh http add sslcert ipport=<ipaddress>:<port> appid=<application ID from saved config including the {}> certhash=<certificate hash from saved config> certstorename=<certificate store name from saved config> clientcertnegotiation=enable

If you have multiple SSL bindings, you'll repeat the process for each of them. Hopefully this helps save someone else the hours and hours of headache this issue caused me.

EDIT: In my experience, you can't actually run the netsh http add sslcert command from the command line directly. You'll need to enter the netsh prompt first by typing netsh and then issue your command like http add sslcert ipport=... in order for it to work.

That's the HTML data attribute. See this for more detail: http://html5doctor.com/html5-custom-data-attributes/

Basically it's just a container of your custom data while still making the HTML valid. It's data- plus some unique identifier.

As an alternative to using the import approach described in several answers, have a look a the configparser module.

The ConfigParser class implements a basic configuration file parser language which provides a structure similar to what you would find on Microsoft Windows INI files. You can use this to write Python programs which can be customized by end users easily.

No. Its not possible to add link through css. But you can use jquery

$('.case').each(function() {
  var link = $(this).html();
  $(this).contents().wrap('<a href="example.com/script.php?id="></a>');
});

Here the demo: http://jsfiddle.net/r5uWX/1/

I cannot replicate the results discussed here.

I don't know if poor benchmark code is to blame, or what, but the two methods are within 10% of each other on my machine using the following code, and one loop is usually just slightly faster than two - as you'd expect.

Array sizes ranged from 2^16 to 2^24, using eight loops. I was careful to initialize the source arrays so the += assignment wasn't asking the FPU to add memory garbage interpreted as a double.

I played around with various schemes, such as putting the assignment of b[j], d[j] to InitToZero[j] inside the loops, and also with using += b[j] = 1 and += d[j] = 1, and I got fairly consistent results.

As you might expect, initializing b and d inside the loop using InitToZero[j] gave the combined approach an advantage, as they were done back-to-back before the assignments to a and c, but still within 10%. Go figure.

Hardware is Dell XPS 8500 with generation 3 Core i7 @ 3.4 GHz and 8 GB memory. For 2^16 to 2^24, using eight loops, the cumulative time was 44.987 and 40.965 respectively. Visual C++ 2010, fully optimized.

PS: I changed the loops to count down to zero, and the combined method was marginally faster. Scratching my head. Note the new array sizing and loop counts.

I'm not sure why it was decided that MFLOPS was a relevant metric. I though the idea was to focus on memory accesses, so I tried to minimize the amount of floating point computation time. I left in the +=, but I am not sure why.

A straight assignment with no computation would be a cleaner test of memory access time and would create a test that is uniform irrespective of the loop count. Maybe I missed something in the conversation, but it is worth thinking twice about. If the plus is left out of the assignment, the cumulative time is almost identical at 31 seconds each.

db.<collection>.find({}, {field1: <value>, field2: <value> ...})

In your example, you can do something like:

db.students.find({}, {"roll":true, "_id":false})

Projection

The projection parameter determines which fields are returned in the matching documents. The projection parameter takes a document of the following form:

{ field1: <value>, field2: <value> ... }

The <value> can be any of the following:

1. 1 or true to include the field in the return documents.

2. 0 or false to exclude the field.

NOTE

For the _id field, you do not have to explicitly specify _id: 1 to return the _id field. The find() method always returns the _id field unless you specify _id: 0 to suppress the field.

To adjust the length of the samples:

set key samplen X

(default is 4)

To adjust the vertical spacing of the samples:

set key spacing X

(default is 1.25)

and (for completeness), to adjust the fontsize:

set key font "<face>,<size>"

(default depends on the terminal)

And of course, all these can be combined into one line:

set key samplen 2 spacing .5 font ",8"

Note that you can also change the position of the key using set key at <position> or any one of the pre-defined positions (which I'll just defer to help key at this point)

How to fish and while using strict code. There are two prerequisite functions needed at the bottom of this post.

xml_add('before', id_('element_after'), '<span xmlns="http://www.w3.org/1999/xhtml">Some text.</span>');

xml_add('after', id_('element_before'), '<input type="text" xmlns="http://www.w3.org/1999/xhtml" />');

xml_add('inside', id_('element_parent'), '<input type="text" xmlns="http://www.w3.org/1999/xhtml" />');

Add multiple elements (namespace only needs to be on the parent element):

xml_add('inside', id_('element_parent'), '<div xmlns="http://www.w3.org/1999/xhtml"><input type="text" /><input type="button" /></div>');

Dynamic reusable code:

function id_(id) {return (document.getElementById(id)) ? document.getElementById(id) : false;}

function xml_add(pos, e, xml)
{
 e = (typeof e == 'string' && id_(e)) ? id_(e) : e;

 if (e.nodeName)
 {
  if (pos=='after') {e.parentNode.insertBefore(document.importNode(new DOMParser().parseFromString(xml,'application/xml').childNodes[0],true),e.nextSibling);}
  else if (pos=='before') {e.parentNode.insertBefore(document.importNode(new DOMParser().parseFromString(xml,'application/xml').childNodes[0],true),e);}
  else if (pos=='inside') {e.appendChild(document.importNode(new DOMParser().parseFromString(xml,'application/xml').childNodes[0],true));}
  else if (pos=='replace') {e.parentNode.replaceChild(document.importNode(new DOMParser().parseFromString(xml,'application/xml').childNodes[0],true),e);}
  //Add fragment and have it returned.
 }
}

Besides checking the right minSdkVersion in build.gradle, make sure you have installed all necessary tools and correct SDK Platform for your preferred Android Version in SDK Manager. In Android Studio klick on Tools -> Android -> SDK Manager. Then install at minimum (for Android 2.2 without emulator):

• Android SDK Tools
• Android SDK Platform-tools
• Android SDK Build-tools (latest)
• Android 2.2 (API 8)
  • SDK Platform
  • Google APIs

This is what worked for me.

For people that have PowerShell 3 or later (i.e. Windows Server 2012+ or Windows Server 2008 R2 with the Windows Management Framework 4.0 update), you can do this one-liner instead of invoking System.Net.WebRequest:

Following the useful comments, I've completely rebuilt the date formatter. Usage is supposed to:

• Be short (one liner)
• Represent disposable objects (time zone, format) as Strings
• Support useful, sortable ISO formats and the legacy format from the box

If you consider this code useful, I may publish the source and a JAR in github.

Usage

// The problem - not UTC
Date.toString()                      
"Tue Jul 03 14:54:24 IDT 2012"

// ISO format, now
PrettyDate.now()        
"2012-07-03T11:54:24.256 UTC"

// ISO format, specific date
PrettyDate.toString(new Date())         
"2012-07-03T11:54:24.256 UTC"

// Legacy format, specific date
PrettyDate.toLegacyString(new Date())   
"Tue Jul 03 11:54:24 UTC 2012"

// ISO, specific date and time zone
PrettyDate.toString(moonLandingDate, "yyyy-MM-dd hh:mm:ss zzz", "CST") 
"1969-07-20 03:17:40 CDT"

// Specific format and date
PrettyDate.toString(moonLandingDate, "yyyy-MM-dd")
"1969-07-20"

// ISO, specific date
PrettyDate.toString(moonLandingDate)
"1969-07-20T20:17:40.234 UTC"

// Legacy, specific date
PrettyDate.toLegacyString(moonLandingDate)
"Wed Jul 20 08:17:40 UTC 1969"

An authentication token should be used instead of the account password. Go to GitHub settings/applications and then create a personal access token. The token can be used the same way a password is used.

The token is intended to allow users not use the account password for project work. Only use the password when doing administration work, like creating new tokens or revoke old tokens.

Instead of a token or password that grants a user whole access to a GitHub account, a project specific deployment key can be used to grant access to a single project repository. A Git project can be configured to use this different key in the following steps when you still can access other Git accounts or projects with your normal credential:

1. Write an SSH configuration file that contains the Host, IdentityFile for the deployment key, maybe the UserKnownHostsFile, and maybe the User (though I think you don't need it).
2. Write an SSH wrapper shell script that virtually is ssh -F /path/to/your/config $*
3. Prepend GIT_SSH=/path/to/your/wrapper in front of your normal Git command. Here the git remote (origin) must use the [email protected]:user/project.git format.

Add an EditText on top of your listview in its .xml layout file. And in your activity/fragment..

lv = (ListView) findViewById(R.id.list_view);
    inputSearch = (EditText) findViewById(R.id.inputSearch);

// Adding items to listview
adapter = new ArrayAdapter<String>(this, R.layout.list_item, R.id.product_name,    products);
lv.setAdapter(adapter);       
inputSearch.addTextChangedListener(new TextWatcher() {

    @Override
    public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
        // When user changed the Text
        MainActivity.this.adapter.getFilter().filter(cs);
    }

    @Override
    public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) { }

    @Override
    public void afterTextChanged(Editable arg0) {}
});

The basic here is to add an OnTextChangeListener to your edit text and inside its callback method apply filter to your listview's adapter.

EDIT

To get filter to your custom BaseAdapter you"ll need to implement Filterable interface.

class CustomAdapter extends BaseAdapter implements Filterable {

    public View getView(){
    ...
    }
    public Integer getCount()
    {
    ...
    }

    @Override
    public Filter getFilter() {

        Filter filter = new Filter() {

            @SuppressWarnings("unchecked")
            @Override
            protected void publishResults(CharSequence constraint, FilterResults results) {

                arrayListNames = (List<String>) results.values;

                // perform your search here using the searchConstraint String.

                constraint = constraint.toString().toLowerCase();
                for (int i = 0; i < mDatabaseOfNames.size(); i++) {
                    String dataNames = mDatabaseOfNames.get(i);
                    if (dataNames.toLowerCase().startsWith(constraint.toString()))  {

                results.count = FilteredArrayNames.size();
                results.values = FilteredArrayNames;
                Log.e("VALUES", results.values.toString());

                return results;
            }
        };

        return filter;
    }
}

Inside performFiltering() you need to do actual comparison of the search query to values in your database. It will pass its result to publishResults() method.

I ran into the same issue and couldn't decide between laughing or smashing my head on the table when I read this error...

What git really tries to tell you: "You are already in a merge state and need to resolve the conflicts there first!"

You tried a merge and a conflict occured. Then, git stays in the merge state and if you want to resolve the merge with other commands git thinks you want to execute a new merge and so it tells you you can't do this because of your current unmerged files...

You can leave this state with git merge --abort and now try to execute other commands.

In my case I tried a pull and wanted to resolve the conflicts by hand when the error occured...

As just formulated by grepsedawk, the answer lies in the -l option of g++, calling ld. If you look at the man page of this command, you can either do:

• g++ -l:libmagic.so.1 [...]
• or: g++ -lmagic [...] , if you have a symlink named libmagic.so in your libs path

I'm not aware of anything like a single table that lets you compare all of them in at one glance (I'm not sure such a table would even be feasible).

Of course the ISO standard document enumerates the complexity requirements in detail, sometimes in various rather readable tables, other times in less readable bullet points for each specific method.

Also the STL library reference at http://www.cplusplus.com/reference/stl/ provides the complexity requirements where appropriate.

We can use data.table to get it quickly. First create df without factors,

df <- data.frame(list(A=c("","xyz","jkl"), B=c(12,"",100)), stringsAsFactors=F)

Now you can use

setDT(df)
for (jj in 1:ncol(df)) set(df, i = which(df[[jj]]==""), j = jj, v = NA)

and you can convert it back to a data.frame

setDF(df)

If you only want to use data.frame and keep factors it's more difficult, you need to work with

levels(df$value)[levels(df$value)==""] <- NA

where value is the name of every column. You need to insert it in a loop.

You have to use new operator here to instantiate. For example:

Contacts.add(new Data(name, address, contact));

I have spent lot of time for solution and got it worked finally by making changes in the server side.Check the website https://docs.microsoft.com/en-us/aspnet/core/security/cors

It worked for me when I enabled corse in the server side.We were using Asp.Net core in API and the below code worked

1) Added Addcors in ConfigureServices of Startup.cs

public void ConfigureServices(IServiceCollection services)
    {
        services.AddCors();
        services.AddMvc();
    }

2) Added UseCors in Configure method as below:

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        app.UseCors(builder =>builder.AllowAnyOrigin());
        app.UseMvc();
    }

In response to Ben Lesh's answer, there should be this line

ng-init="somethingHere = somethingHere || options[0]" 

instead of

ng-init="somethingHere = somethingHere || options[0].value" 

That is,

<select ng-model="somethingHere"_x000D_
        ng-init="somethingHere = somethingHere || options[0]"_x000D_
        ng-options="option.name for option in options track by option.value">_x000D_
</select>

I changed a bit and it worked like this, dumped into one single array, provided all the images are of same dimensions.

png = []
for image_path in glob.glob("./train/*.png"):
    png.append(misc.imread(image_path))    

im = np.asarray(png)

print 'Importing done...', im.shape

Multiline comment in bash

: <<'END_COMMENT'
This is a heredoc (<<) redirected to a NOP command (:).
The single quotes around END_COMMENT are important,
because it disables variable resolving and command resolving
within these lines.  Without the single-quotes around END_COMMENT,
the following two $() `` commands would get executed:
$(gibberish command)
`rm -fr mydir`
comment1
comment2 
comment3
END_COMMENT

The syntax is wrong in this clause (and similar ones)

    CASE lkey WHEN lkey > 5 THEN
        lkey + 2
    ELSE
        lkey
    END

It's either

    CASE WHEN [condition] THEN [expression] ELSE [expression] END

or

    CASE [expression] WHEN [value] THEN [expression] ELSE [expression] END

So in your case it would read:

    CASE WHEN lkey > 5 THEN
        lkey + 2
    ELSE
        lkey
    END

Check out the documentation (The CASE expression):

In my case, changing the order of Maven Dependencies from Build Path configuration did not work for me. I changed its order from Run configuration.
Follow these steps:
• Go to Run -> Run Configurations...
• Click on the unit test's run configuration and click on the Classpath tab.
• check Use temporary JAR to specify classpath (to avoid classpath length limitations).
May be it is enough and your test works. You should try, so press Run button. If it did not work. Follow all previous steps again and without pressing Run button, go to the next step.
• In sub branches of User Entries move Maven Dependencies above your project or test class.
• Click Run button.

If all you need is to ensure uniqueness of elements, then HashSet is what you need.

What do you mean when you say "just a set implementation"? A set is (by definition) a collection of unique elements that doesn't save element order.

Interfaces can not contain any implementation (including default values). You need to switch to abstract class.

// sample data
$requiredKeys = ['key1', 'key2', 'key3'];
$arrayToValidate = ['key1' => 1, 'key2' => 2, 'key3' => 3];

function keysExist(array $requiredKeys, array $arrayToValidate) {
    if ($requiredKeys === array_keys($arrayToValidate)) {
        return true;
    }

    return false;
}

I found the answer :)

Use JsonPath or XmlPath (in case you have XML) to get data from the response body.

In my case:

JsonPath jsonPath = new JsonPath(responseBody);
int user_id = jsonPath.getInt("user_id");

Got this issue after I upgraded PostgreSQL 9.4 to 9.6. The 9.4 binary package had PgAdmin 3 while 9.6 came with PgAdmin 4. I resolved it after a clean installation (I completely uninstalled and reinstalled) of PostgreSQL.

However, under different circumstances, you could try running the pgAdmin 4 application as an Administrator. This should fix the error.

A simple rule for us to remember what to use in which case:

• [S]ingle quotes are for [S]trings ; [D]ouble quotes are for [D]atabase identifiers;

In MySQL and MariaDB, the ` (backtick) symbol is the same as the " symbol. You can use " when your SQL_MODE has ANSI_QUOTES enabled.

You are creating those bytes objects yourself:

item['title'] = [t.encode('utf-8') for t in title]
item['link'] = [l.encode('utf-8') for l in link]
item['desc'] = [d.encode('utf-8') for d in desc]
items.append(item)

Each of those t.encode(), l.encode() and d.encode() calls creates a bytes string. Do not do this, leave it to the JSON format to serialise these.

Next, you are making several other errors; you are encoding too much where there is no need to. Leave it to the json module and the standard file object returned by the open() call to handle encoding.

You also don't need to convert your items list to a dictionary; it'll already be an object that can be JSON encoded directly:

class W3SchoolPipeline(object):    
    def __init__(self):
        self.file = open('w3school_data_utf8.json', 'w', encoding='utf-8')

    def process_item(self, item, spider):
        line = json.dumps(item) + '\n'
        self.file.write(line)
        return item

I'm guessing you followed a tutorial that assumed Python 2, you are using Python 3 instead. I strongly suggest you find a different tutorial; not only is it written for an outdated version of Python, if it is advocating line.decode('unicode_escape') it is teaching some extremely bad habits that'll lead to hard-to-track bugs. I can recommend you look at Think Python, 2nd edition for a good, free, book on learning Python 3.

I was led to this post when searching for solution for similar problem. Tim's answer was very helpful. like Matt Baker, I just want to shut off httpClient log without too much configuration. As we were not sure which logging implementation underneath common-logging was used, My solution was to force it using log4j by throwing log4j jar file in the class path. Default setting of log4j configuration shuts off common-httpclient debug output. Of course, to make it more robust, you may create common-logging.properties and log4j.properties files to further define your logging configurations.

It happened to me that I had an instance of the packager running with an old project (I ran react-native start as usual). I was using Ubuntu 14.04. So what I did was to stop that instance and go to my project folder and in two different console tabs I ran these two commands separately:

npm start #here I used to run react-native start
react-native run-android

npm start is defined in my package.json as:

"start": "node_modules/react-native/packager/packager.sh"

I don't know if there is a sort of confusing stuff for react-native but that did the trick.

Memory management in Linux is a bit tricky to understand, and I can't say I fully understand it yet, but I'll try to share a little bit of my experience and knowledge.

Short answer to your question: Yes there are other stuff included than whats in the list.

What's being shown in your list is applications run in userspace. The kernel uses memory for itself and modules, on top of that it also has a lower limit of free memory that you can't go under. When you've reached that level it will try to free up resources, and when it can't do that anymore, you end up with an OOM problem.

From the last line of your list you can read that the kernel reports a total-vm usage of: 1498536kB (1,5GB), where the total-vm includes both your physical RAM and swap space. You stated you don't have any swap but the kernel seems to think otherwise since your swap space is reported to be full (Total swap = 524284kB, Free swap = 0kB) and it reports a total vmem size of 1,5GB.

Another thing that can complicate things further is memory fragmentation. You can hit the OOM killer when the kernel tries to allocate lets say 4096kB of continous memory, but there are no free ones availible.

Now that alone probably won't help you solve the actual problem. I don't know if it's normal for your program to require that amount of memory, but I would recommend to try a static code analyzer like cppcheck to check for memory leaks or file descriptor leaks. You could also try to run it through Valgrind to get a bit more information out about memory usage.

The example below is an adaptation and simplification of a longer post from We ? Swift. This is what it will look like:

Create a New Project

It can be just the usual Single View Application.

Add the Code

Replace the ViewController.swift code with the following:

import UIKit
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
    
    // Data model: These strings will be the data for the table view cells
    let animals: [String] = ["Horse", "Cow", "Camel", "Sheep", "Goat"]
    
    // cell reuse id (cells that scroll out of view can be reused)
    let cellReuseIdentifier = "cell"
    
    // don't forget to hook this up from the storyboard
    @IBOutlet var tableView: UITableView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // Register the table view cell class and its reuse id
        self.tableView.register(UITableViewCell.self, forCellReuseIdentifier: cellReuseIdentifier)
        
        // (optional) include this line if you want to remove the extra empty cell divider lines
        // self.tableView.tableFooterView = UIView()

        // This view controller itself will provide the delegate methods and row data for the table view.
        tableView.delegate = self
        tableView.dataSource = self
    }
    
    // number of rows in table view
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return self.animals.count
    }
    
    // create a cell for each table view row
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        
        // create a new cell if needed or reuse an old one
        let cell:UITableViewCell = self.tableView.dequeueReusableCell(withIdentifier: cellReuseIdentifier) as UITableViewCell!
        
        // set the text from the data model
        cell.textLabel?.text = self.animals[indexPath.row]
        
        return cell
    }
    
    // method to run when table view cell is tapped
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        print("You tapped cell number \(indexPath.row).")
    }
}

Read the in-code comments to see what is happening. The highlights are

• The view controller adopts the UITableViewDelegate and UITableViewDataSource protocols.
• The numberOfRowsInSection method determines how many rows there will be in the table view.
• The cellForRowAtIndexPath method sets up each row.
• The didSelectRowAtIndexPath method is called every time a row is tapped.

Add a Table View to the Storyboard

Drag a UITableView onto your View Controller. Use auto layout to pin the four sides.

Hook up the Outlets

Control drag from the Table View in IB to the tableView outlet in the code.

Finished

That's all. You should be able run your app now.

This answer was tested with Xcode 9 and Swift 4

Variations

Row Deletion

You only have to add a single method to the basic project above if you want to enable users to delete rows. See this basic example to learn how.

Row Spacing

If you would like to have spacing between your rows, see this supplemental example.

Custom cells

The default layout for the table view cells may not be what you need. Check out this example to help get you started making your own custom cells.

Dynamic Cell Height

Sometimes you don't want every cell to be the same height. Starting with iOS 8 it is easy to automatically set the height depending on the cell content. See this example for everything you need to get you started.

To me it happened in DogController that autowired DogService that autowired DogRepository. Dog class used to have field name but I changed it to coolName, but didn't change methods in DogRepository: Dog findDogByName(String name). I change that method to Dog findDogByCoolName(String name) and now it works.

Listed are the steps that could rectify the error:

1. Press Windows+R
2. Type services.msc and strike Enter
3. Find all services
4. Starting with ora start these services and wait!!
5. When your server specific service is initialized (in my case it was orcl)
6. Now run mysql or whatever you are using and start coding.P

This problem occured for me one time when I had already opened the built-in Android Emulator (AVD). Check if you turned off it before start changing anything in settings.

I personally use JSON Viewer since the Notepad++ plugin doesn't work any more.

EDIT - 24th May 2012

I advise that you download the JSMin plugin for Notepad as mentioned in the answer. This works well for me in the latest version (v6.1.2 at time of writing).

EDIT - 7th November 2017

As per @danday74's comment below, JSMin is now JSToolNpp. Also, please be aware that the JSON Viewer tool is on Codeplex which will likely disappear in the near future.

Given the above, this answer is no longer relevant and you should use Dan H's answer instead. My answer is simply here for posterity.

https://github.com/kubernetes/helm/blob/master/docs/charts_tips_and_tricks.md#user-content-automatically-roll-deployments-when-configmaps-or-secrets-change

Often times configmaps or secrets are injected as configuration files in containers. Depending on the application a restart may be required should those be updated with a subsequent helm upgrade, but if the deployment spec itself didn't change the application keeps running with the old configuration resulting in an inconsistent deployment.

The sha256sum function can be used together with the include function to ensure a deployments template section is updated if another spec changes:

kind: Deployment
spec:
  template:
    metadata:
      annotations:
        checksum/config: {{ include (print $.Template.BasePath "/secret.yaml") . | sha256sum }}
[...]

In my case, for some reasons, $.Template.BasePath didn't work but $.Chart.Name does:

spec:
  replicas: 1
  template:
    metadata:
      labels:
        app: admin-app
      annotations:
        checksum/config: {{ include (print $.Chart.Name "/templates/" $.Chart.Name "-configmap.yaml") . | sha256sum }}

All of the tech podcasts I listen to have been mentioned, but as long as we're discussing video I'd like to mention Hak.5. It is more focused on using existing programs rather than coding, but it has some good hardware segments, and it can often be an excellent source of inspiration.

You have to do this:

class Bar : public Foo
{
    // ...
}

The default inheritance type of a class in C++ is private, so any public and protected members from the base class are limited to private. struct inheritance on the other hand is public by default.

VB.NET

 MyList.OrderBy(Function(f) f.StartDate).ThenByDescending(Function(f) f.EndDate)

OR

  From l In MyList Order By l.StartDate Ascending, l.EndDate Descending

If you insist on running the .html file locally and not serving it with a webserver, you can prevent those cross origin requests from happening in the first place by making the problematic resources available inline.

I had this problem when trying to to serve .js files through file://. My solution was to update my build script to replace <script src="..."> tags with <script>...</script>. Here's a gulp approach for doing that:

1. run npm install --save-dev to packages gulp, gulp-inline and del.

2. After creating a gulpfile.js to the root directory, add the following code (just change the file paths for whatever suits you):

let gulp = require('gulp');
let inline = require('gulp-inline');
let del = require('del');

gulp.task('inline', function (done) {
    gulp.src('dist/index.html')
    .pipe(inline({
        base: 'dist/',
        disabledTypes: 'css, svg, img'
    }))
    .pipe(gulp.dest('dist/').on('finish', function(){
        done()
    }));
});

gulp.task('clean', function (done) {
    del(['dist/*.js'])
    done()
});

gulp.task('bundle-for-local', gulp.series('inline', 'clean'))

3. Either run gulp bundle-for-local or update your build script to run it automatically.

You can see the detailed problem and solution for my case here.

From .NET 2.0 you shouldn't need to do this. If you do not explicitly set the Proxy property on a web request it uses the value of the static WebRequest.DefaultWebProxy. If you wanted to change the proxy being used by all subsequent WebRequests, you can set this static DefaultWebProxy property.

The default behaviour of WebRequest.DefaultWebProxy is to use the same underlying settings as used by Internet Explorer.

If you wanted to use different proxy settings to the current user then you would need to code

WebRequest webRequest = WebRequest.Create("http://stackoverflow.com/");
webRequest.Proxy = new WebProxy("http://proxyserver:80/",true);

or

WebRequest.DefaultWebProxy = new WebProxy("http://proxyserver:80/",true);

You should also remember the object model for proxies includes the concept that the proxy can be different depending on the destination hostname. This can make things a bit confusing when debugging and checking the property of webRequest.Proxy. Call

webRequest.Proxy.GetProxy(new Uri("http://google.com.au")) to see the actual details of the proxy server that would be used.

There seems to be some debate about whether you can set webRequest.Proxy or WebRequest.DefaultWebProxy = null to prevent the use of any proxy. This seems to work OK for me but you could set it to new DefaultProxy() with no parameters to get the required behaviour. Another thing to check is that if a proxy element exists in your applications config file, the .NET Framework will NOT use the proxy settings in Internet Explorer.

The MSDN Magazine article Take the Burden Off Users with Automatic Configuration in .NET gives further details of what is happening under the hood.

Just run setup_xampp.bat from shell (shell from XAMPP control panel)and the paths should be set automatically for the portable version of XAMPP for windows. It has worked for me.

All the other answers are correct, but you also need to call your method correctly:

Calculate(5, 5, Operator.PLUS))

And since you use int for left and right, the result will be int as well (3/2 will result in 1). you could cast to double before calculating the result or modify your parameters to accept double

I always seem to find myself landing here only to realize that the title and question are not quite aligned.

If you want a moment date from a string:

const myMomentObject = moment(str, 'YYYY-MM-DD')

From moment documentation:

Instead of modifying the native Date.prototype, Moment.js creates a wrapper for the Date object.

If you instead want a javascript Date object from a string:

const myDate = moment(str, 'YYYY-MM-DD').toDate();

No need to hack settings. There is a simple way:

print(df.to_string())

2. adb push ~/Downloads/tcpdump /sdcard/
3. adb shell
4. su root
5. mv /sdcard/tcpdump /data/local/
6. cd /data/local/
7. chmod +x tcpdump
8. ./tcpdump -vv -i any -s 0 -w /sdcard/dump.pcap
9. Ctrl+C once you've captured enough data.
10. exit
11. exit
12. adb pull /sdcard/dump.pcap ~/Downloads/

Now you can open the pcap file using Wireshark.

As for your question about monitoring specific processes, find the bundle id of your app, let's call it com.android.myapp

1. ps | grep com.android.myapp
2. copy the first number you see from the output. Let's call it 1234. If you see no output, you need to start the app.
3. Download strace to ~/Downloads and put into /data/local using the same way you did for tcpdump above.
4. cd /data/local
5. ./strace -p 1234 -f -e trace=network -o /sdcard/strace.txt

Now you can look at strace.txt for ip addresses, and filter your wireshark log for those IPs.

Kiran's answer is definetely the answer for my case.

In code part I split string to 4000 char strings and try to put them in to db.

Explodes with this error.

The cause of the error is using utf chars, those counts 2 bytes each. Even I truncate to 4000 chars in code(sth. like String.Take(4000)), oracle considers 4001 when string contains 'ö' or any other non-eng(non ascii to be precise, which are represented with two or bytes in utf8) characters.

git reset <hash>  # you need to know the last good hash, so you can remove all your local commits

git fetch upstream
git checkout master
git merge upstream/master
git push origin master -f

voila, now your fork is back to same as upstream.

lookup only works on localhost. If you want to retrieve variables from a variables file you made remotely use include_vars: {{ varfile }} . Contents of {{ varfile }} should be a dictionary of the form {"key":"value"}, you will find ansible gives you trouble if you include a space after the colon.

if none of those solutions didn't work for you, try adding after

.trigger( "change" );

ex.

$("#baba").val("").trigger( "change" );

or

$("#baba").val(false).trigger( "change" );

or

$("#baba option").prop("selected", false).trigger( "change" );

or

$('#baba').prop('selectedIndex',-1).trigger( "change" );

or

$('#baba option:first').prop('selected',true).trigger( "change" );

I guess its enough to return absolute path..

 Path.GetFileName( Request.Url.AbsolutePath )

using System.IO;

If you like to use a GUI, you can perform the entire operation with gitk.

gitk --reflog

This will allow you to see the branch's commit history as if the branch hadn't been deleted. Now simply right click on the most recent commit to the branch and select the menu option Create new branch.

You need to sample the load average for several seconds and calculate the CPU utilization from that. If unsure what to you, get the sources of "top" and read it.

If you are using JPA with EclipseLink, you'll have to set the @PrivateOwned annotation.

Documentation: Eclipse Wiki - Using EclipseLink JPA Extensions - Chapter 1.4 How to Use the @PrivateOwned Annotation

Yes, I try to follow it as closely as possible.

I don't follow any other coding standards.

I think you should make a subquery to do grouping. In this case inner subquery returns few rows and you don't need a CASE statement. So I think this is going to be faster:

select Detail.ReceiptDate AS 'DATE',
       SUM(TotalMailed),
       SUM(TotalReturnMail),
       SUM(TraceReturnedMail)

from
(

select SentDate AS 'ReceiptDate', 
       count('TotalMailed') AS TotalMailed, 
       0 as TotalReturnMail, 
       0 as TraceReturnedMail
from MailDataExtract
where sentdate is not null
GROUP BY SentDate

UNION ALL
select MDE.ReturnMailDate AS 'ReceiptDate', 
       0 AS TotalMailed, 
       count(TotalReturnMail) as TotalReturnMail, 
       0 as TraceReturnedMail
from MailDataExtract MDE
where MDE.ReturnMailDate is not null
GROUP BY  MDE.ReturnMailDate

UNION ALL

select MDE.ReturnMailDate AS 'ReceiptDate', 
       0 AS TotalMailed, 
       0 as TotalReturnMail, 
       count(TraceReturnedMail) as TraceReturnedMail

from MailDataExtract MDE
    inner join DTSharedData.dbo.ScanData SD 
        ON SD.ScanDataID = MDE.ReturnScanDataID
   where MDE.ReturnMailDate is not null AND SD.ReturnMailTypeID = 1
GROUP BY MDE.ReturnMailDate

) as Detail
GROUP BY Detail.ReceiptDate
ORDER BY 1

I have the same issue, when I try to export the content of email to csv and still keep it break line when importing to excel.

I export the conent as this: ="Line 1"&CHAR(10)&"Line 2"

When I import it to excel(google), excel understand it as string. It still not break new line.

We need to trigger excel to treat it as formula by: Format -> Number | Scientific.

This is not the good way but it resolve my issue.

Use:

git checkout -b serverfix origin/serverfix

This is a common enough operation that Git provides the --track shorthand:

git checkout --track origin/serverfix

In fact, this is so common that there’s even a shortcut for that shortcut. If the branch name you’re trying to checkout (a) doesn’t exist and (b) exactly matches a name on only one remote, Git will create a tracking branch for you:

git checkout serverfix

To set up a local branch with a different name than the remote branch, you can easily use the first version with a different local branch name:

git checkout -b sf origin/serverfix

Now, your local branch sf will automatically pull from origin/serverfix.

One more alternative, in the case you are working with the Appstore, need "Entitlements" and as such need to link with an Apple-Framework.

For Entitlements to work (e.g. GameCenter) you need to have a "Link Binary with Libraries"-buildstep and then link with "GameKit.framework". CMake "injects" the libraries on a "low level" into the commandline, hence Xcode doesn't really know about it, and as such you will not get GameKit enabled in the Capabilities screen.

One way to use CMake and have a "Link with Binaries"-buildstep is to generate the xcodeproj with CMake, and then use 'sed' to 'search & replace' and add the GameKit in the way XCode likes it...

The script looks like this (for Xcode 6.3.1).

s#\/\* Begin PBXBuildFile section \*\/#\/\* Begin PBXBuildFile section \*\/\

save this to "gamecenter.sed" and then "apply" it like this ( it changes your xcodeproj! )

sed -i.pbxprojbak -f gamecenter.sed myproject.xcodeproj/project.pbxproj

You might have to change the script-commands to fit your need.

Warning: it's likely to break with different Xcode-version as the project-format could change, the (hardcoded) unique number might not really by unique - and generally the solutions by other people are better - so unless you need to Support the Appstore + Entitlements (and automated builds), don't do this.

This is a CMake bug, see http://cmake.org/Bug/view.php?id=14185 and http://gitlab.kitware.com/cmake/cmake/issues/14185

If you using roles you could check for ROLE_USER that is the solution i use:

if (TRUE === $this->get('security.authorization_checker')->isGranted('ROLE_USER')) {
    // user is logged in
} 

Selection is its own object within VBA. It functions much like a Range object.

Selection and Range do not share all the same properties and methods, though, so for ease of use it might make sense just to create a range and set it equal to the Selection, then you can deal with it programmatically like any other range.

Dim myRange as Range
Set myRange = Selection

Here is my Java code for Selenium WebDriver. Write the following method and call it during assertion:

protected boolean isElementPresent(By by){
        try{
            driver.findElement(by);
            return true;
        }
        catch(NoSuchElementException e){
            return false;
        }
    }

Swift 4 You cannot compare Any to nil.Because an optional can be nil and hence it always succeeds to true. The only way is to cast it to your desired object and compare it to nil.

if (someone as? String) != nil
{
   //your code`enter code here`
}

String.prototype.replaceAll = function (needle, replacement) {
    return this.replace(new RegExp(needle, 'g'), replacement);
};

I didn't use it myself but heard of a simple tool (not a text editor) for this so it is definitely possible without setting up a programming environment (by installing octave or python).

A quick search hints that it was possible with total commander. (A lightweight tool with an easy point and click interface)

I would not be surprised if this still works, but I can't guarantee it.

You may try:

wget --user-agent=Mozilla --content-disposition --mirror --convert-links -E -K -p http://example.com/

Also you can add:

-A pdf,ps,djvu,tex,doc,docx,xls,xlsx,gz,ppt,mp4,avi,zip,rar

to accept the specific extensions, or to reject only specific extensions:

-R html,htm,asp,php

or to exclude the specific areas:

-X "search*,forum*"

If the files are ignored for robots (e.g. search engines), you've to add also: -e robots=off

You can use the static from() method from the LayoutInflater class:

 LayoutInflater li = LayoutInflater.from(context);

Kevlar is correct.

An alternative to a custom DLL is Lua Alien

ORDER BY a.C_ID

Here I found this article which is send post request using JsonConvert.SerializeObject() & StringContent() to HttpClient.PostAsync data

static async Task Main(string[] args)
{
    var person = new Person();
    person.Name = "John Doe";
    person.Occupation = "gardener";

    var json = Newtonsoft.Json.JsonConvert.SerializeObject(person);
    var data = new System.Net.Http.StringContent(json, Encoding.UTF8, "application/json");

    var url = "https://httpbin.org/post";
    using var client = new HttpClient();

    var response = await client.PostAsync(url, data);

    string result = response.Content.ReadAsStringAsync().Result;
    Console.WriteLine(result);
}

You are falling for a subtle quirk. You cannot re-assign module-level variables inside a python function. I think this is there to stop people re-assigning stuff inside a function by accident.

You can access the module namespace, you just shouldn't try to re-assign. If your function assigns something, it automatically becomes a function variable - and python won't look in the module namespace.

You can do:

__DB_NAME__ = None

def func():
    if __DB_NAME__:
        connect(__DB_NAME__)
    else:
        connect(Default_value)

but you cannot re-assign __DB_NAME__ inside a function.

One workaround:

__DB_NAME__ = [None]

def func():
    if __DB_NAME__[0]:
        connect(__DB_NAME__[0])
    else:
        __DB_NAME__[0] = Default_value

Note, I'm not re-assigning __DB_NAME__, I'm just modifying its contents.

Try using replaceWith() or replaceAll()

Edit the following entry in the run.conf file. But if you have multiple JVMs running on the same JBoss, you might want to run it via command line argument of -Xms2g -Xmx4g (or whatever your preferred start/max memory settings are.

    JAVA_OPTS="-Xms2g -Xmx4g -XX:MaxPermSize=256m -Dorg.jboss.resolver.warning=true

You can verify your SSH key passphrase by attempting to load it into your SSH agent. With OpenSSH this is done via ssh-add.

Once you're done, remember to unload your SSH passphrase from the terminal by running ssh-add -d.

Example

$( document ).ready(function() {_x000D_
  $('.msg').html('hello world');_x000D_
});

    <!DOCTYPE html>_x000D_
    <html>_x000D_
      <head>_x000D_
        <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>    _x000D_
      </head>_x000D_
      <body>_x000D_
        <div class="msg"></div>_x000D_
      </body>_x000D_
    </html>

This code will fulifil your need:

   FileWriter fw=new FileWriter("C:\\file.json",true);
   fw.write("ssssss");
   fw.close();

They all are unique, yes

If you're sure that your values are unique you can iterate over the entries of your old map .

Map<String, Character> myNewHashMap = new HashMap<>();
for(Map.Entry<Character, String> entry : myHashMap.entrySet()){
    myNewHashMap.put(entry.getValue(), entry.getKey());
}

Alternatively, you can use a Bi-Directional map like Guava provides and use the inverse() method :

BiMap<Character, String> myBiMap = HashBiMap.create();
myBiMap.put('a', "test one");
myBiMap.put('b', "test two");

BiMap<String, Character> myBiMapInversed = myBiMap.inverse();

As java-8 is out, you can also do it this way :

Map<String, Integer> map = new HashMap<>();
map.put("a",1);
map.put("b",2);

Map<Integer, String> mapInversed = 
    map.entrySet()
       .stream()
       .collect(Collectors.toMap(Map.Entry::getValue, Map.Entry::getKey))

Finally, I added my contribution to the proton pack library, which contains utility methods for the Stream API. With that you could do it like this:

Map<Character, String> mapInversed = MapStream.of(map).inverseMapping().collect();

just wrap your content with a table like this:

  <table width="100%" height="100%">
         <tr align="center">
               <th align="center">
                 text
               </th>
          </tr>
  </table><

First method

For Windows 7 and above users, Windows PowerShell give you this option. Users with windows version less than 7 can download PowerShell online and install it.

Steps:

1. type PowerShell in search area and click on "Windows PowerShell"

2. If you have a .bat (batch) file go to step 3 OR copy your commands to a file and save it with .bat extension (e.g. file.bat)

3. run the .bat file with following command

   PS (location)> <path to bat file>/file.bat | Tee-Object -file log.txt

This will generate a log.txt file with all command prompt output in it. Advantage is that you can also the output on command prompt.

Second method

You can use file redirection (>, >>) as suggest by Bali C above.

I will recommend first method if you have lots of commands to run or a script to run. I will recommend last method if there is only few commands to run.

Just to answer your question and not to continue any discussions. The Apache Harmony JDK implementation seems to use a different algorithm, at least it looks totally different:

Sun JDK

public int hashCode() {
    int h = hash;
    if (h == 0) {
        int off = offset;
        char val[] = value;
        int len = count;

        for (int i = 0; i < len; i++) {
            h = 31*h + val[off++];
        }
        hash = h;
    }
    return h;
}

Apache Harmony

public int hashCode() {
    if (hashCode == 0) {
        int hash = 0, multiplier = 1;
        for (int i = offset + count - 1; i >= offset; i--) {
            hash += value[i] * multiplier;
            int shifted = multiplier << 5;
            multiplier = shifted - multiplier;
        }
        hashCode = hash;
    }
    return hashCode;
}

3. On the next page, scroll to the bottom of the page and click Merge pull request and Confirm merge.

The select statement in the cost part of your select is returning more than one value. You need to add more where clauses, or use an aggregation.

you can also use perl -e

perl -e 'print 67/8'

When a module is loaded from a file in Python, __file__ is set to its path. You can then use that with other functions to find the directory that the file is located in.

Taking your examples one at a time:

A = os.path.join(os.path.dirname(__file__), '..')
# A is the parent directory of the directory where program resides.

B = os.path.dirname(os.path.realpath(__file__))
# B is the canonicalised (?) directory where the program resides.

C = os.path.abspath(os.path.dirname(__file__))
# C is the absolute path of the directory where the program resides.

You can see the various values returned from these here:

import os
print(__file__)
print(os.path.join(os.path.dirname(__file__), '..'))
print(os.path.dirname(os.path.realpath(__file__)))
print(os.path.abspath(os.path.dirname(__file__)))

and make sure you run it from different locations (such as ./text.py, ~/python/text.py and so forth) to see what difference that makes.

I just want to address some confusion first. __file__ is not a wildcard it is an attribute. Double underscore attributes and methods are considered to be "special" by convention and serve a special purpose.

http://docs.python.org/reference/datamodel.html shows many of the special methods and attributes, if not all of them.

In this case __file__ is an attribute of a module (a module object). In Python a .py file is a module. So import amodule will have an attribute of __file__ which means different things under difference circumstances.

Taken from the docs:

__file__ is the pathname of the file from which the module was loaded, if it was loaded from a file. The __file__ attribute is not present for C modules that are statically linked into the interpreter; for extension modules loaded dynamically from a shared library, it is the pathname of the shared library file.

In your case the module is accessing it's own __file__ attribute in the global namespace.

To see this in action try:

# file: test.py

print globals()
print __file__

And run:

python test.py

{'__builtins__': <module '__builtin__' (built-in)>, '__name__': '__main__', '__file__':
 'test_print__file__.py', '__doc__': None, '__package__': None}
test_print__file__.py

For future Googlers, If you get an error similar below after you trigger click for a polygon

"Uncaught TypeError: Cannot read property 'vertex' of undefined"

then try the code below

google.maps.event.trigger(polygon, "click", {});

docker export -o <nameOfContainer>.tar <nameOfContainer>

Might need to prune the existing container using docker prune ...

Import with required modifications:

cat <nameOfContainer>.tar | docker import -c "ENTRYPOINT service mysql start && /bin/bash" - <nameOfContainer>

Run the container for example with always restart option to make sure it will auto resume after host/daemon recycle:

docker run -d -t -i --restart always --name <nameOfContainer> <nameOfContainer> /bin/bash

Side note: In my opinion reasonable is to start only cron service leaving container as clean as possible then just modify crontab or cron.hourly, .daily etc... with corresponding checkup/monitoring scripts. Reason is You rely only on one daemon and in case of changes it is easier with ansible or puppet to redistribute cron scripts instead of track services that start at boot.

If you've got VS2010 installed, you ought to find a .NET 4.0 gacutil at

C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\NETFX 4.0 Tools

The 7.0A Windows SDK should have been installed alongside VS2010 - 6.0A will have been installed with VS2008, and hence won't have .NET 4.0 support.

Some of the tutorials I found that are easy to understand are:

• http://www.phpfreaks.com/tutorial/basic-pagination

It makes way more sense to break up your list into page-sized chunks, and only query your database one chunk at a time. This drastically reduces server processing time and page load time, as well as gives your user smaller pieces of info to digest, so he doesn't choke on whatever crap you're trying to feed him. The act of doing this is called pagination.

A basic pagination routine seems long and scary at first, but once you close your eyes, take a deep breath, and look at each piece of the script individually, you will find it's actually pretty easy stuff

The script:

// find out how many rows are in the table 
$sql = "SELECT COUNT(*) FROM numbers";
$result = mysql_query($sql, $conn) or trigger_error("SQL", E_USER_ERROR);
$r = mysql_fetch_row($result);
$numrows = $r[0];

// number of rows to show per page
$rowsperpage = 10;
// find out total pages
$totalpages = ceil($numrows / $rowsperpage);

// get the current page or set a default
if (isset($_GET['currentpage']) && is_numeric($_GET['currentpage'])) {
   // cast var as int
   $currentpage = (int) $_GET['currentpage'];
} else {
   // default page num
   $currentpage = 1;
} // end if

// if current page is greater than total pages...
if ($currentpage > $totalpages) {
   // set current page to last page
   $currentpage = $totalpages;
} // end if
// if current page is less than first page...
if ($currentpage < 1) {
   // set current page to first page
   $currentpage = 1;
} // end if

// the offset of the list, based on current page 
$offset = ($currentpage - 1) * $rowsperpage;

// get the info from the db 
$sql = "SELECT id, number FROM numbers LIMIT $offset, $rowsperpage";
$result = mysql_query($sql, $conn) or trigger_error("SQL", E_USER_ERROR);

// while there are rows to be fetched...
while ($list = mysql_fetch_assoc($result)) {
   // echo data
   echo $list['id'] . " : " . $list['number'] . "<br />";
} // end while

/******  build the pagination links ******/
// range of num links to show
$range = 3;

// if not on page 1, don't show back links
if ($currentpage > 1) {
   // show << link to go back to page 1
   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=1'><<</a> ";
   // get previous page num
   $prevpage = $currentpage - 1;
   // show < link to go back to 1 page
   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$prevpage'><</a> ";
} // end if 

// loop to show links to range of pages around current page
for ($x = ($currentpage - $range); $x < (($currentpage + $range) + 1); $x++) {
   // if it's a valid page number...
   if (($x > 0) && ($x <= $totalpages)) {
      // if we're on current page...
      if ($x == $currentpage) {
         // 'highlight' it but don't make a link
         echo " [<b>$x</b>] ";
      // if not current page...

What about opacity

#mybox:hover {
    opacity: 0;
}

For Linux based OS. I had such an issue due to a corrupted path but was able to temporarily fix the issue and my git was immediately restored.

In case you're facing such path issue type the command below

export PATH="/usr/bin:/bin:$PATH"

Nice explanation and example above. I found this (JSON.stringify() array bizarreness with Prototype.js) to complete the answer. Some sites implements its own toJSON with JSONFilters, so delete it.

if(window.Prototype) {
    delete Object.prototype.toJSON;
    delete Array.prototype.toJSON;
    delete Hash.prototype.toJSON;
    delete String.prototype.toJSON;
}

it works fine and the output of the test:

console.log(json);

Result:

"{"a":"test","b":["item","item2","item3"]}"

Compare Side-By-Side looks like the most convenient to me though it's not the most popular:

UPD: I need to add that this plugin can freeze ST while comparing big files. It is certainly not the best decision if you are going to compare large texts.

Try this

$("#globalsearchstr").focus(function(){
    $(this).parent().css("background", "url('../images/r-srchbg_white.png') no-repeat");
});

The easiest way to do this, is using cstdio's printf. Actually, i'm surprised that anyone mentioned printf! anyway, you need to include the library, like this...

#include<cstdio>

int main() {
    double total;
    cin>>total;
    printf("%.2f\n", total);
}

This will print the value of "total" (that's what %, and then ,total does) with 2 floating points (that's what .2f does). And the \n at the end, is just the end of line, and this works with UVa's judge online compiler options, that is:

g++ -lm -lcrypt -O2 -pipe -DONLINE_JUDGE filename.cpp

the code you are trying to run will not run with this compiler options...

In IntelliJ Do as they say in eclipse "If you're facing this problem with Eclipse, I've been following many different solutions but the one that worked for me is this:

Right click your project folder and open up Properties.

From the right panel, select Java Build Path then go to Libraries tab.

Select Add External JARs to import the mysql driver.

From the right panel, select Deployment Assembly.

Select Add..., then select Java Build Path Entries and click Next.

You should see the sql driver on the list. Select it and click first.

And that's it! Try to run it again! Cheers!"

Here we have to add the jar file in Project Structure -> Libraries -> +(add)

Add:

build.gradle 

in your root project folder, and use plugin for example:

apply plugin: 'idea'
//and standard one
apply plugin: 'java'

and with this fire from command line:

gradle cleanIdea 

and after that:

gradle idea

After that everything should work

Use datetime module:

from datetime import datetime
ts = int("1284101485")

# if you encounter a "year is out of range" error the timestamp
# may be in milliseconds, try `ts /= 1000` in that case
print(datetime.utcfromtimestamp(ts).strftime('%Y-%m-%d %H:%M:%S'))

With Java 8's Base64 API

byte[] decodedImg = Base64.getDecoder()
                    .decode(encodedImg.getBytes(StandardCharsets.UTF_8));
Path destinationFile = Paths.get("/path/to/imageDir", "myImage.jpg");
Files.write(destinationFile, decodedImg);

If your encoded image starts with something like data:image/png;base64,iVBORw0..., you'll have to remove the part. See this answer for an easy way to do that.

As answered by Naaz direct renaming of s3 is not possible.

i have attached a code snippet which will copy all the contents

code is working just add your aws access key and secret key

here's what i did in code

-> copy the source folder contents(nested child and folders) and pasted in the destination folder

-> when the copying is complete, delete the source folder

package com.bighalf.doc.amazon;

The lattice library is another good option. Here I've added a legend on the right side and jittered the points because some of them overlapped.

xyplot(Sepal.Width ~ Sepal.Length, group=Species, data=iris, 
       auto.key=list(space="right"), 
       jitter.x=TRUE, jitter.y=TRUE)

Assignment expressions from PEP 572 (new in Python 3.8) offer yet another way to solve this:

time_interval = [4, 6, 12]

total_time = 0
cum_time = [total_time := total_time + t for t in time_interval]

html input runing for live chance.

<input type="text" name="v7"  class="priceformat"/>
<input type="text" name="v8"  class="priceformat"/>


$('.priceformat').each(function( index ) {
    $(this).priceFormat({ prefix: '',  thousandsSeparator: '' });
});

//5000.00

//5.000,00

//5,000.00

You could also use FilenameUtils from Apache. It provides you at least the following features for the example C:\dev\project\file.txt:

• the prefix - C:\
• the path - dev\project\
• the full path - C:\dev\project\
• the name - file.txt
• the base name - file
• the extension - txt

I tried the standard library's calendar.timegm and it works quite well:

# convert a datetime to milliseconds since Epoch
def datetime_to_utc_milliseconds(aDateTime):
    return int(calendar.timegm(aDateTime.timetuple())*1000)

Ref: https://docs.python.org/2/library/calendar.html#calendar.timegm

         if(!/^(0?[1-9]|[12][0-9]|3[01])[\/\-](0?[1-9]|1[012])[\/\-]\d{2}$/.test($(this).val())){
                     alert('Date format incorrect (DD/MM/YY)');
                     $(this).datepicker('setDate', "");
                     return false;
                }

This code will validate date format DD/MM/YY

From this blog post:

• self refers to the current class
• self can be used to call static functions and reference static member variables
• self can be used inside static functions
• self can also turn off polymorphic behavior by bypassing the vtable
• $this refers to the current object
• $this can be used to call static functions
• $this should not be used to call static member variables. Use self instead.
• $this can not be used inside static functions

ANTLR mega tutorial by Gabriele Tomassetti is very helpful

How many thousands of users?

I've run some TCP/IP client/server connection tests in the past on Windows 2003 Server and managed more than 70,000 connections on a reasonably low spec VM. (see here for details: http://www.lenholgate.com/blog/2005/10/the-64000-connection-question.html). I would be extremely surprised if Windows 2008 Server is limited to less than 2003 Server and, IMHO, the posting that Cloud links to is too vague to be much use. This kind of question comes up a lot, I blogged about why I don't really think that it's something that you should actually worry about here: http://www.serverframework.com/asynchronousevents/2010/12/one-million-tcp-connections.html.

Personally I'd test it and see. Even if there is no inherent limit in the Windows 2008 Server version that you intend to use there will still be practical limits based on memory, processor speed and server design.

If you want to run some 'generic' tests you can use my multi-client connection test and the associated echo server. Detailed here: http://www.lenholgate.com/blog/2005/11/windows-tcpip-server-performance.html and here: http://www.lenholgate.com/blog/2005/11/simple-echo-servers.html. These are what I used to run my own tests for my server framework and these are what allowed me to create 70,000 active connections on a Windows 2003 Server VM with 760MB of memory.

Edited to add details from the comment below...

If you're already thinking of multiple servers I'd take the following approach.

1. Use the free tools that I link to and prove to yourself that you can create a reasonable number of connections onto your target OS (beware of the Windows limits on dynamic ports which may cause your client connections to fail, search for MAX_USER_PORT).

2. during development regularly test your actual server with test clients that can create connections and actually 'do something' on the server. This will help to prevent you building the server in ways that restrict its scalability. See here: http://www.serverframework.com/asynchronousevents/2010/10/how-to-support-10000-or-more-concurrent-tcp-connections-part-2-perf-tests-from-day-0.html

Have you tried

adb kill-server
adb shell

Sometimes adb gets stuck and first killing adb server and then starting some command forces authorization window to pop-up.

Also please check adb client version on your phone. THis feature is supported from adb 1.0.31 as far as I remember.

I'm using nGram, too. I use standard tokenizer and nGram just as a filter. Here is my setup:

{
  "index": {
    "index": "my_idx",
    "type": "my_type",
    "analysis": {
      "index_analyzer": {
        "my_index_analyzer": {
          "type": "custom",
          "tokenizer": "standard",
          "filter": [
            "lowercase",
            "mynGram"
          ]
        }
      },
      "search_analyzer": {
        "my_search_analyzer": {
          "type": "custom",
          "tokenizer": "standard",
          "filter": [
            "standard",
            "lowercase",
            "mynGram"
          ]
        }
      },
      "filter": {
        "mynGram": {
          "type": "nGram",
          "min_gram": 2,
          "max_gram": 50
        }
      }
    }
  }
}

Let's you find word parts up to 50 letters. Adjust the max_gram as you need. In german words can get really big, so I set it to a high value.

If the child element is inline (e.g not a div, table etc) I would wrap it up inside a div or a p and make the wrapper's text align css property equal to center.

    <div id="container">
        This text is aligned to the left.<br>
        So is this text.<br>
        <div style="text-align: center">
            This <button>button</button> is centered.
        </div>
        This text is still aligned left.
    </div>

Otherwise, if the element is a block (display: block, e.g a div or a p) with a fixed width, I'd set its margin left and right css properties to auto.

    <div id="container">
        This text is aligned to the left.<br>
        So is this text.<br>
        <div style="margin: 0 auto; width: 200px; background: red; color: white;">
            My parent is centered.
        </div>
        This text is still aligned left.
    </div>

You could of course add a text-align: center to the wrapper element to make its contents centered as well.

I won't bother with positioning because IMHO its not the way to go for the OPs problem but be sure to check this link out, very helpful.

When using xml-apis-1.0, you can serialize and deserialize this:

<?xml version="1.0" encoding="UTF-8"?>
<root>
    <map>
        <key>value</key>
        <key2>value2</key2>
    </map>
</root>

        Unmarshaller unmarshaller = jc.createUnmarshaller();
        Root root = (Root) unmarshaller.unmarshal(new File("src/input.xml"));

        System.out.println(root.map.getAsMap());

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(root, System.out);

        } catch (ParserConfigurationException e) {
            throw new RuntimeException(e);
        }

        for (Entry<String, String> entry : values.entrySet()) {
            Element mapElement = document.createElement(entry.getKey());
            mapElement.appendChild(document.createTextNode(entry.getValue()));
            elements.add(mapElement);
        }
    }

    public Map<String, String> getAsMap() {
        Map<String, String> map = new HashMap<String, String>();

        for (Element element : elements) {
            if (element.getNodeType() == Node.ELEMENT_NODE) {
                map.put(element.getLocalName(), element.getFirstChild().getNodeValue());
            }
        }

        return map;
    }
}

You can achieve the desired result by requesting a list of distinct ids instead of a list of distinct hydrated objects.

Simply add this to your criteria:

criteria.setProjection(Projections.distinct(Projections.property("id")));

Now you'll get the correct number of results according to your row-based limiting. The reason this works is because the projection will perform the distinctness check as part of the sql query, instead of what a ResultTransformer does which is to filter the results for distinctness after the sql query has been performed.

Worth noting is that instead of getting a list of objects, you will now get a list of ids, which you can use to hydrate objects from hibernate later.

Personally, I'm reluctant to use these for anything but debugging messages. I have done it, but I try not to show that kind of information to customers or end users. My customers are not engineers and are sometimes not computer savvy. I might log this info to the console, but, as I said, reluctantly except for debug builds or for internal tools. I suppose it does depend on the customer base you have, though.

You can achieve this by using the following query:

EXEC sp_msforeachdb 
    'IF EXISTS
    (
        SELECT  1 
        FROM    [?].sys.objects 
        WHERE   name LIKE ''OBJECT_TO_SEARCH''
    )
    SELECT 
        ''?''       AS DB, 
        name        AS Name, 
        type_desc   AS Type 
    FROM [?].sys.objects 
    WHERE name LIKE ''OBJECT_TO_SEARCH'''

Just replace OBJECT_TO_SEARCH with the actual object name you are interested in (or part of it, surrounded with %).

Here is a sample script that I recently used in a Gateway POST transaction that receives a GET response. Are you using this in a custom C# form? Whatever your purpose, just replace the String fields (username, password, etc.) with the parameters from your form.

private String readHtmlPage(string url)
   {

    //setup some variables

    String username  = "demo";
    String password  = "password";
    String firstname = "John";
    String lastname  = "Smith";

    //setup some variables end

      String result = "";
      String strPost = "username="+username+"&password="+password+"&firstname="+firstname+"&lastname="+lastname;
      StreamWriter myWriter = null;

      HttpWebRequest objRequest = (HttpWebRequest)WebRequest.Create(url);
      objRequest.Method = "POST";
      objRequest.ContentLength = strPost.Length;
      objRequest.ContentType = "application/x-www-form-urlencoded";

      try
      {
         myWriter = new StreamWriter(objRequest.GetRequestStream());
         myWriter.Write(strPost);
      }
      catch (Exception e) 
      {
         return e.Message;
      }
      finally {
         myWriter.Close();
      }

      HttpWebResponse objResponse = (HttpWebResponse)objRequest.GetResponse();
      using (StreamReader sr = 
         new StreamReader(objResponse.GetResponseStream()) )
      {
         result = sr.ReadToEnd();

         // Close and clean up the StreamReader
         sr.Close();
      }
      return result;
   } 

I give all my popovers anchors the class activate_popover. I activate them all at once onload

$('body').popover({selector: '.activate-popover', html : true, container: 'body'})

to get the click away functionality working I use (in coffee script):

$(document).on('click', (e) ->
  clickedOnActivate = ($(e.target).parents().hasClass("activate-popover") || $(e.target).hasClass("activate-popover"))
  clickedAway = !($(e.target).parents().hasClass("popover") || $(e.target).hasClass("popover"))
if clickedAway && !clickedOnActivate
  $(".popover.in").prev().popover('hide')
if clickedOnActivate 
  $(".popover.in").prev().each () ->
    if !$(this).is($(e.target).closest('.activate-popover'))
      $(this).popover('hide')
)

Which works perfectly fine with bootstrap 2.3.1

I would use nearly the same way but with list as buffer for read integers:

static Object[] readFile(String fileName) {
    Scanner scanner = new Scanner(new File(fileName));
    List<Integer> tall = new ArrayList<Integer>();
    while (scanner.hasNextInt()) {
        tall.add(scanner.nextInt());
    }

    return tall.toArray();
}

They may look a bit different from normal HTML, but : and @ are valid chars for attribute names and all Vue.js supported browsers can parse it correctly. In addition, they do not appear in the final rendered markup. The shorthand syntax is totally optional, but you will likely appreciate it when you learn more about its usage later.

Source: official documentation.

If you have your connection string added in your web.config, make sure that "Integrated Security=false;" so it would use the id and password specified in the web.config.

<connectionStrings>
    <add providerName="System.Data.SqlClient" name="MyDbContext" connectionString="Data Source=localhost,1433;Initial Catalog=MyDatabase;user id=MyUserName;Password=MyPassword;Trusted_Connection=true;Integrated Security=false;" />
</connectionStrings>

Sometimes, I've wanted random strings that are semi-pronounceable, semi-memorable.

import random

def randomWord(length=5):
    consonants = "bcdfghjklmnpqrstvwxyz"
    vowels = "aeiou"

    return "".join(random.choice((consonants, vowels)[i%2]) for i in range(length))

Then,

>>> randomWord()
nibit
>>> randomWord()
piber
>>> randomWord(10)
rubirikiro

To avoid 4-letter words, don't set length to 4.

You can cheat! Say your div is 20px high, place the div at the top of the next container and set

position: absolute;
top: -20px;

It may not be semantically clean but does scale with responsive designs

A nonblocking call returns immediately with whatever data are available: the full number of bytes requested, fewer, or none at all.

An asynchronous call requests a transfer that will be performed in its whole(entirety) but will complete at some future time.

I'm too having problems with breakpoints in application_start with IIS a hosted app. A good workaround is using Debugger.Break(); in code instead of the VS breakpoint

If you have installed a node package and are still getting message that the package is undefined, you might have an issue with the PATH linking to the binary. Just to clarify a binary and executable essentially do the same thing, which is to execute a package or application. ei webpack... executes the node package webpack.

In both Windows and Linux there is a global binary folder. In Windows I believe it's something like C://Windows/System32 and in Linux it's usr/bin. When you open the terminal/command prompt, the profile of it links the PATH variable to the global bin folder so you are able to execute packages/applications from it.

My best guess is that installing webpack globally may not have successfully put the executable file in the global binary folder. Without the executable there, you will get an error message. It could be another issue, but it is safe to say the that if you are here reading this, running webpack globally is not working for you.

My resolution to this problem is to do away with running webpack globally and link the PATH to the node_module binary folder, which is /node_modules/.bin.

WINDOWS: add node_modules/.bin to your PATH. Here is a tutorial on how to change the PATH variable in windows.

LINUX: Go to your project root and execute this...

export PATH=$PWD/node_modules/.bin:$PATH 

In Linux you will have to execute this command every time you open your terminal. This link here shows you how to make a change to your PATH variable permanent.

I have soled the problem by changing target android version to 28 in project.properties (target=android-28) and installed cordova-plugin-androidx and cordova-plugin-androidx-adapter.

Both if (one.length() > 0) {} and if (!"".equals(one)) {} will check against an empty foo parameter, and an empty parameter is what you'd get if the the form is submitted with no value in the foo text field.

If there's any chance you can use the Expression Language to handle the parameter, you could access it with empty param.foo in an expression.

<c:if test='${not empty param.foo}'>

You won't see a simple answer because there isn't one.

First, Unicode doesn't contain "every character from every language", although it sure does try.

Unicode itself is a mapping, it defines codepoints and a codepoint is a number, associated with usually a character. I say usually because there are concepts like combining characters. You may be familiar with things like accents, or umlauts. Those can be used with another character, such as an a or a u to create a new logical character. A character therefore can consist of 1 or more codepoints.

To be useful in computing systems we need to choose a representation for this information. Those are the various unicode encodings, such as utf-8, utf-16le, utf-32 etc. They are distinguished largely by the size of of their codeunits. UTF-32 is the simplest encoding, it has a codeunit that is 32bits, which means an individual codepoint fits comfortably into a codeunit. The other encodings will have situations where a codepoint will need multiple codeunits, or that particular codepoint can't be represented in the encoding at all (this is a problem for instance with UCS-2).

Because of the flexibility of combining characters, even within a given encoding the number of bytes per character can vary depending on the character and the normalization form. This is a protocol for dealing with characters which have more than one representation (you can say "an 'a' with an accent" which is 2 codepoints, one of which is a combining char or "accented 'a'" which is one codepoint).

In Visual Studio 2010 right click your project name. Hit "View Windows Settings", this generates and opens a file called "app.manifest". Within this file replace "asInvoker" with "requireAdministrator" as explained in the commented sections within the file.

For Windows:

• Open device manager
• Find Unknown "Android" device (likely listed under Other devices with an exclamation mark)
• Update driver
• Browse my computer for driver software
• Let me pick from a list of devices, select List All Devices
• Under "Android device" or "Google Inc", you will find "Android Bootloader Interface"
• Choose "Android Bootloader Interface"
• Click "yes" when it says that driver might not be compatible

Just adding more info, I wasn't able to find sn.exe utility in the mentioned locations, in my case it was in C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\bin

You can always use this attached to some click event in your script:

location.href = this.href;

example of usage is:

jQuery('a').click(function(e) {
    location.href = this.href;
});

I had this identical problem, I was using django-rest-knox for authentication tokens. It turns out that nothing was wrong with my fetch method which looked like this:

...
    let headers = {"Content-Type": "application/json"};
    if (token) {
      headers["Authorization"] = `Token ${token}`;
    }
    return fetch("/api/instruments/", {headers,})
      .then(res => {
...

I was running apache.

What solved this problem for me was changing WSGIPassAuthorization to 'On' in wsgi.conf.

I had a Django app deployed on AWS EC2, and I used Elastic Beanstalk to manage my application, so in the django.config, I did this:

container_commands:
  01wsgipass:
    command: 'echo "WSGIPassAuthorization On" >> ../wsgi.conf'

How to import a commons-library into netbeans.

1. Evaluate the error message in NetBeans:

   java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
   

2. NoClassDeffFoundError means somewhere under the hood in the code you used, a method called another method which invoked a class that cannot be found. So what that means is your code did this: MyFoobarClass foobar = new MyFoobarClass() and the compiler is confused because nowhere is defined this MyFoobarClass. This is why you get an error.

3. To know what to do next, you have to look at the error message closely. The words 'org/apache/commons' lets you know that this is the codebase that provides the tools you need. You have a choice, either you can import EVERYTHING in apache commons, or you could import JUST the LogFactory class, or you could do something in between. Like for example just get the logging bit of apache commons.

4. You'll want to go the middle of the road and get commons-logging. Excellent choice, fire up the google and search for apache commons-logging. The first link takes you to http://commons.apache.org/proper/commons-logging/. Go to downloads. There you will find the most up-to-date ones. If your project was compiled under ancient versions of commons-logging, then use those same ancient ones because if you use the newer ones, the code may fail because the newer versions are different.

5. You're going to want to download the commons-logging-1.1.3-bin.zip or something to that effect. Read what the name is saying. The .zip means it's a compressed file. commons-logging means that this one should contain the LogFactory class you desire. the middle 1.1.3 means that is the version. if you are compiling for an old version, you'll need to match these up, or else you risk the code not compiling right due to changes due to upgrading.

6. Download that zip. Unzip it. Search around for things that end in .jar. In netbeans right click your project, click properties, click libraries, click "add jar/folder" and import those jars. Save the project, and re-run, and the errors should be gone.

The binaries don't include the source code, so you won't be able to drill down and see what is happening when you debug. As programmers you should be downloading "the source" of apache commons and compiling from source, generating the jars yourself and importing those for experience. You should be smart enough to understand and correct the source code you are importing. These ancient versions of apache commons might have been compiled under an older version of Java, so if you go too far back, they may not even compile unless you compile them under an ancient version of java.

According to MDN, the way to retrieve an item from a NodeList is:

nodeItem = nodeList.item(index)

Thus:

var slides = document.getElementsByClassName("slide");
for (var i = 0; i < slides.length; i++) {
   Distribute(slides.item(i));
}

I haven't tried this myself (the normal for loop has always worked for me), but give it a shot.

These terms are unfortunately overloaded with several possible definitions. According to the ANSI-SPARC "three schema" model for instance, the Conceptual Schema or Conceptual Model consists of the set of objects in a database (tables, views, etc) in contrast to the External Schema which are the objects that users see.

In the data management professions and especially among data modellers / architects, the term Conceptual Model is frequently used to mean a semantic model whereas the term Logical Model is used to mean a preliminary or virtual database design. This is probably the usage you are most likely to come across in the workplace.

In academic usage and when describing DBMS architectures however, the Logical level means the database objects (tables, views, tables, keys, constraints, etc), as distinct from the Physical level (files, indexes, storage). To confuse things further, in the workplace the term Physical model is often used to mean the design as implemented or planned for implementation in an actual database. That may include both "physical" and "logical" level constructs (both tables and indexes for example).

When you come across any of these terms you really need to seek clarification on what is being described unless the context makes it obvious.

For a discussion of these differences, check out Data Modelling Essentials by Simsion and Witt for example.

I use the blow function in my GeneralUtils class, check it may be useful

    public String getFieldType(Object o) {
    if (o == null) {
        return "Unable to identify the class name";
    }
    return o.getClass().getName();
}

If jQuery is okay, you can use find(). It's basically equivalent to the way you are doing it right now.

$('#note').find('#textid');

You can also use jQuery selectors to basically achieve the same thing:

$('#note #textid');

Using these methods to get something that already has an ID is kind of strange, but I'm supplying these assuming it's not really how you plan on using it.

On a side note, you should know ID's should be unique in your webpage. If you plan on having multiple elements with the same "ID" consider using a specific class name.

Update 2020.03.10

It's a breeze to use native JS for this:

document.querySelector('#note #textid');

If you want to first find #note then #textid you have to check the first querySelector result. If it fails to match, chaining is no longer possible :(

var parent = document.querySelector('#note');
var child = parent ? parent.querySelector('#textid') : null;

For DEFAULT CURRENT_TIMESTAMP:

ALTER TABLE tablename
 CHANGE COLUMN columnname1 columname1 DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
 CHANGE COLUMN columnname2 columname2 DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP;

Please note double columnname declaration

Removing DEFAULT CURRENT_TIMESTAMP:

ALTER TABLE tablename
 ALTER COLUMN columnname1 DROP DEFAULT,
 ALTER COLUMN columnname2 DROPT DEFAULT;
