This has been answered a few times but here's one more just for fun :-)

public class Tmp {
    public static void main(String[] args) {
        System.out.println(swapChars("abcde", 0, 1));
    }
    private static String swapChars(String str, int lIdx, int rIdx) {
        StringBuilder sb = new StringBuilder(str);
        char l = sb.charAt(lIdx), r = sb.charAt(rIdx);
        sb.setCharAt(lIdx, r);
        sb.setCharAt(rIdx, l);
        return sb.toString();
    }
}

For me, this issue occurred after updating Google Play Services. One of the libraries I was using incorporated this library using the "+" in its gradel reference, like

compile 'com.google.android.gms:play-services:+'

This created an issue because the min version targeted by that library was less than what was targeted by the current version of Google Play Services. I found this by simply looking in the logs.

Do this:

data = [4, 5, 6]

def print_data():
    global data
    print(data)

print_data()

I had a similar situation trying to exec() a backend command and also getting no tty present and no askpass program specified in the web server error log. Original (bad) code:

$output = array();
$return_var = 0;
exec('sudo my_command', $output, $return_var);

A bash wrapper solved this issue, such as:

$output = array();
$return_var = 0;
exec('sudo bash -c "my_command"', $output, $return_var);

Not sure if this will work in every case. Also, be sure to apply the appropriate quoting/escaping rules on my_command portion.

I found that if the chosen perspective doesn't match the type of the current file, then "go to matching brace" doesn't work. However, changing perspectives makes it work again. So, for example, when I have a PHP file open, but, say, the Java perspective active, pressing Ctrl + Shift + P does nothing. For the same file with the PHP perspective active, pressing Ctrl + Shift + P does exactly what you'd expect and puts my cursor beside the closing brace relative to the one it started at.

execute

show VARIABLES like "%char%”;

find character-set-server if is not utf8mb4.

set it in your my.cnf, like

vim /etc/my.cnf

add one line

character_set_server = utf8mb4

at last restart mysql

To call the method, you need to qualify function with self.. In addition to that, if you want to pass a filename, add a filename parameter (or other name you want).

class MyHandler(FileSystemEventHandler):

    def on_any_event(self, event):
        srcpath = event.src_path
        print (srcpath, 'has been ',event.event_type)
        print (datetime.datetime.now())
        filename = srcpath[12:]
        self.dropbox_fn(filename) # <----

    def dropbox_fn(self, filename):  # <-----
        print('In dropbox_fn:', filename)

To post JSON with jQuery in JavaScript, use JSON.stringify to dump the data, and set the content type to application/json.

var value_data = [1, 2, 3, 4];

$.ajax({
    type: 'POST',
    url: '/process',
    data: JSON.stringify(value_data),
    contentType: 'application/json',
    success: function (response_data) {
        alert("success");
    }   
});

Parse it in Flask with request.get_json().

data = request.get_json()

This also works - evaluate, if capital is defined. If not, this means, that capital is undefined or null (or other value, that evaluates to false in js)

if (capital && capital.length < 1) {do your stuff}

This is for setting PATH on Mac OS X Version 10.9.5.

I have tried to add $HOME because I use user profile :

echo 'export PATH="$PATH:$HOME/.composer/vendor/bin"' >> ~/.bashrc

When you do not use user profile:

echo 'export PATH="$PATH:~/.composer/vendor/bin"' >> ~/.bashrc

Then reload:

source ~/.bashrc

I hope this help you.

This post is now nearly 5 years old! Python-2.7 will stop receiving official updates from python.org in 2020. Also, Python-3.7 has been released. Check out Python-Future on how to make your Python-2 code compatible with Python-3. For updating conda, the documentation now recommends using conda update --all in each of your conda environments to update all packages and the Python executable for that version. Also, since they changed their name to Anaconda, I don't know if the Windows registry keys are still the same.

There have been no updates to Python(x,y) since June of 2015, so I think it's safe to assume it has been abandoned.

As @cxw comments below, these answers are for the same bit-versions, and by bit-version I mean 64-bit vs. 32-bit. For example, these answers would apply to updating from 64-bit Python-2.7.10 to 64-bit Python-2.7.11, ie: the same bit-version. While it is possible to install two different bit versions of Python together, it would require some hacking, so I'll save that exercise for the reader. If you don't want to hack, I suggest that if switching bit-versions, remove the other bit-version first.

• Anaconda and MiniConda can be used with an existing Python installation by disabling the options to alter the Windows PATH and Registry. After extraction, create a symlink to conda in your bin or install conda from PyPI. Then create another symlink called conda-activate to activate in the Anaconda/Miniconda root bin folder. Now Anaconda/Miniconda is just like Ruby RVM. Just use conda-activate root to enable Anaconda/Miniconda.
• Portable Python is no longer being developed or maintained.

TL;DR

• Using Anaconda or miniconda, then just execute conda update --all to keep each conda environment updated,
• same major version of official Python (e.g. 2.7.5), just install over old (e.g. 2.7.4),
• different major version of official Python (e.g. 3.3), install side-by-side with old, set paths/associations to point to dominant (e.g. 2.7), shortcut to other (e.g. in BASH $ ln /c/Python33/python.exe python3).

The answer depends:

1. If OP has 2.7.x and wants to install newer version of 2.7.x, then

   • if using MSI installer from the official Python website, just install over old version, installer will issue warning that it will remove and replace the older version; looking in "installed programs" in "control panel" before and after confirms that the old version has been replaced by the new version; newer versions of 2.7.x are backwards compatible so this is completely safe and therefore IMHO multiple versions of 2.7.x should never necessary.
   • if building from source, then you should probably build in a fresh, clean directory, and then point your path to the new build once it passes all tests and you are confident that it has been built successfully, but you may wish to keep the old build around because building from source may occasionally have issues. See my guide for building Python x64 on Windows 7 with SDK 7.0.
   • if installing from a distribution such as Python(x,y), see their website. Python(x,y) has been abandoned. I believe that updates can be handled from within Python(x,y) with their package manager, but updates are also included on their website. I could not find a specific reference so perhaps someone else can speak to this. Similar to ActiveState and probably Enthought, Python (x,y) clearly states it is incompatible with other installations of Python:

     It is recommended to uninstall any other Python distribution before installing Python(x,y)

   • Enthought Canopy uses an MSI and will install either into Program Files\Enthought or home\AppData\Local\Enthought\Canopy\App for all users or per user respectively. Newer installations are updated by using the built in update tool. See their documentation.
   • ActiveState also uses an MSI so newer installations can be installed on top of older ones. See their installation notes.

     Other Python 2.7 Installations On Windows, ActivePython 2.7 cannot coexist with other Python 2.7 installations (for example, a Python 2.7 build from python.org). Uninstall any other Python 2.7 installations before installing ActivePython 2.7.

   • Sage recommends that you install it into a virtual machine, and provides a Oracle VirtualBox image file that can be used for this purpose. Upgrades are handled internally by issuing the sage -upgrade command.

   • Anaconda can be updated by using the conda command:

     conda update --all
     

     Anaconda/Miniconda lets users create environments to manage multiple Python versions including Python-2.6, 2.7, 3.3, 3.4 and 3.5. The root Anaconda/Miniconda installations are currently based on either Python-2.7 or Python-3.5.

     Anaconda will likely disrupt any other Python installations. Installation uses MSI installer. [UPDATE: 2016-05-16] Anaconda and Miniconda now use .exe installers and provide options to disable Windows PATH and Registry alterations.

     Therefore Anaconda/Miniconda can be installed without disrupting existing Python installations depending on how it was installed and the options that were selected during installation. If the .exe installer is used and the options to alter Windows PATH and Registry are not disabled, then any previous Python installations will be disabled, but simply uninstalling the Anaconda/Miniconda installation should restore the original Python installation, except maybe the Windows Registry Python\PythonCore keys.

     Anaconda/Miniconda makes the following registry edits regardless of the installation options: HKCU\Software\Python\ContinuumAnalytics\ with the following keys: Help, InstallPath, Modules and PythonPath - official Python registers these keys too, but under Python\PythonCore. Also uninstallation info is registered for Anaconda\Miniconda. Unless you select the "Register with Windows" option during installation, it doesn't create PythonCore, so integrations like Python Tools for Visual Studio do not automatically see Anaconda/Miniconda. If the option to register Anaconda/Miniconda is enabled, then I think your existing Python Windows Registry keys will be altered and uninstallation will probably not restore them.

   • WinPython updates, I think, can be handled through the WinPython Control Panel.
   • PortablePython is no longer being developed. It had no update method. Possibly updates could be unzipped into a fresh directory and then App\lib\site-packages and App\Scripts could be copied to the new installation, but if this didn't work then reinstalling all packages might have been necessary. Use pip list to see what packages were installed and their versions. Some were installed by PortablePython. Use easy_install pip to install pip if it wasn't installed.

2. If OP has 2.7.x and wants to install a different version, e.g. <=2.6.x or >=3.x.x, then installing different versions side-by-side is fine. You must choose which version of Python (if any) to associate with *.py files and which you want on your path, although you should be able to set up shells with different paths if you use BASH. AFAIK 2.7.x is backwards compatible with 2.6.x, so IMHO side-by-side installs is not necessary, however Python-3.x.x is not backwards compatible, so my recommendation would be to put Python-2.7 on your path and have Python-3 be an optional version by creating a shortcut to its executable called python3 (this is a common setup on Linux). The official Python default install path on Windows is

   • C:\Python33 for 3.3.x (latest 2013-07-29)
   • C:\Python32 for 3.2.x
   • &c.
   • C:\Python27 for 2.7.x (latest 2013-07-29)
   • C:\Python26 for 2.6.x
   • &c.

3. If OP is not updating Python, but merely updating packages, they may wish to look into virtualenv to keep the different versions of packages specific to their development projects separate. Pip is also a great tool to update packages. If packages use binary installers I usually uninstall the old package before installing the new one.

I hope this clears up any confusion.

Actually you can set some properties of a view's layer through interface builder. I know that I can set a layer's borderWidth and cornerRadius through xcode. borderColor doesn't work, probably because the layer wants a CGColor instead of a UIColor.

You might have to use Strings instead of numbers, but it works!

layer.cornerRadius
layer.borderWidth
layer.borderColor

Update: layer.masksToBounds = true

Update: select appropriate Type for Keypath:

Use the ng-click directive:

<button my-directive ng-click="alertFn()">Click Me!</button>

// In <script>:
app.directive('myDirective' function() {
  return function(scope, element, attrs) {
    scope.alertFn = function() { alert('click'); };
  };
};

Note that you don't need my-directive in this example, you just need something to bind alertFn on the current scope.

Update: You also want the angular libraries loaded before your <script> block.

You can use static constructor to initialization static variable. Static constructor will be entry point for your class

public class MyClass
{

    static MyClass()
    {

        //write your initialization code here
    }

}

Just found that lines below must be added to web.config file, now everything works fine on production server too.

<system.webServer>
  <modules runAllManagedModulesForAllRequests="true" >
   <remove name="UrlRoutingModule"/>    
  </modules>
</system.webServer>

this ans is for eclipse user......

first u check the jdbc jar file is add in Ear libraries....

if yes...then check...in web Content->web Inf folder->lib

and past here jdbc jar file in lib folder.....

Use TO_TIMESTAMP function

TO_TIMESTAMP(date_string,'YYYY-MM-DD HH24:MI:SS')

public class TimeDelay{
  public static void main(String args[]) {
    try {
      while (true) {
        System.out.println(new String("Hello world"));
        Thread.sleep(3 * 1000); // every 3 seconds
      }
    } catch (InterruptedException e) {
      e.printStackTrace();
    }
  }
}

If the above methods are not working for you, you may want to look into changing the encoding of the csv file itself.

Using Excel:

1. Open csv file using Excel
2. Navigate to File menu option and click Save As
3. Click Browse to select a location to save the file
4. Enter intended filename
5. Select CSV (Comma delimited) (*.csv) option
6. Click Tools drop-down box and click Web Options
7. Under Encoding tab, select the option Unicode (UTF-8) from Save this document as drop-down list
8. Save the file

Using Notepad:

1. Open csv file using notepad
2. Navigate to File > Save As option
3. Next, select the location to the file
4. Select the Save as type option as All Files(.)
5. Specify the file name with .csv extension
6. From Encoding drop-down list, select UTF-8 option.
7. Click Save to save the file

By doing this, you should be able to import csv files without encountering the UnicodeCodeError.

Yes regex can certainly be used to extract part of a string. Unfortunately different flavours of *nix and different tools use slightly different Regex variants.

This sed command should work on most flavours (Tested on OS/X and Redhat)

echo '12 BBQ ,45 rofl, 89 lol' | sed  's/^.*,\([0-9][0-9]*\).*$/\1/g'

public interface IContainsMyModel
{
    ViewModel Model { get; }
}

public class ViewModel : IContainsMyModel
{
    public string MyProperty { set; get; }
    public ViewModel Model { get { return this; } }
}

public class Composition : IContainsMyModel
{
    public ViewModel ViewModel { get; set; }
}

Use IContainsMyModel in your layout.

Solved. Interfaces rule.

Here is a simple way to iterate through your custom Enum object

For Each enumValue As Integer In [Enum].GetValues(GetType(MyEnum))

     Print([Enum].GetName(GetType(MyEnum), enumValue).ToString)

Next

I guess you are talking about installation in Ubuntu. Just use:

apt-get install python-numpy python-scipy

That should take care of the BLAS libraries compiling as well. Else, compiling the BLAS libraries is very difficult.

I use a wrapper around array_merge to deal with SeanWM's comment about null arrays; I also sometimes want to get rid of duplicates. I'm also generally wanting to merge one array into another, as opposed to creating a new array. This ends up as:

/**
 * Merge two arrays - but if one is blank or not an array, return the other.
 * @param $a array First array, into which the second array will be merged
 * @param $b array Second array, with the data to be merged
 * @param $unique boolean If true, remove duplicate values before returning
 */
function arrayMerge(&$a, $b, $unique = false) {
    if (empty($b)) {
        return;  // No changes to be made to $a
    }
    if (empty($a)) {
        $a = $b;
        return;
    }
    $a = array_merge($a, $b);
    if ($unique) {
        $a = array_unique($a);
    }
}

1. #include <stdint.h>
2. Use uintptr_t standard type defined in the included standard header file.

In my Angular Bootstrap dropdowns I initialize the JSON Array (vm.zoneDropdown) with ng-init (you can also have ng-init inside the directive template) and I pass the Array in a custom src attribute

<custom-dropdown control-id="zone" label="Zona" model="vm.form.zone" src="vm.zoneDropdown"
                         ng-init="vm.getZoneDropdownSrc()" is-required="true" form="farmaciaForm" css-class="custom-dropdown col-md-3"></custom-dropdown>

Inside the controller:

vm.zoneDropdown = [];
vm.getZoneDropdownSrc = function () {
    vm.zoneDropdown = $customService.getZone();
}

And inside the customDropdown directive template(note that this is only one part of the bootstrap dropdown):

<ul class="uib-dropdown-menu" role="menu" aria-labelledby="btn-append-to-body">
    <li role="menuitem" ng-repeat="dropdownItem in vm.src" ng-click="vm.setValue(dropdownItem)">
        <a ng-click="vm.preventDefault($event)" href="##">{{dropdownItem.text}}</a>
    </li>
</ul>

You can launch the correct version of Spyder by launching from Ananconda's Navigator. From the dropdown, switch to your desired environment and then press the launch Spyder button. You should be able to check the results right away.

To get a definitive reason, you'd need to ask the designer(s) of that API.

But one possible reason is that the intent of a (hypothetical) nextChar would not fit into the scanning model very well.

• If nextChar() to behaved like read() on a Reader and simply returned the next unconsumed character from the scanner, then it is behaving inconsistently with the other next<Type> methods. These skip over delimiter characters before they attempt to parse a value.

• If nextChar() to behaved like (say) nextInt then:

  • the delimiter skipping would be "unexpected" for some folks, and

  • there is the issue of whether it should accept a single "raw" character, or a sequence of digits that are the numeric representation of a char, or maybe even support escaping or something¹.

No matter what choice they made, some people wouldn't be happy. My guess is that the designers decided to stay away from the tarpit.

^{1 - Would vote strongly for the raw character approach ... but the point is that there are alternatives that need to be analysed, etc.}

'\u0000' stands for null . So if you print an uninitialized char variable , you'll get nothing.

Dim rnd As Random = New Random
rnd.Next(n)

Your system can have many different tomcat versions. You can try to solve it.

Right Click on Project then Select Properties, Select Project Facets and on the right section, Select right Apache Tomcat versions as Runtimes and click ok

In Python 3.4 you can use the pathlib module:

>>> from pathlib import Path
>>> p = Path('C:\Program Files\Internet Explorer\iexplore.exe')
>>> p.name
'iexplore.exe'
>>> p.suffix
'.exe'
>>> p.root
'\\'
>>> p.parts
('C:\\', 'Program Files', 'Internet Explorer', 'iexplore.exe')
>>> p.relative_to('C:\Program Files')
WindowsPath('Internet Explorer/iexplore.exe')
>>> p.exists()
True

I used this method:

$(document).mousemove(function(e) {
    window.x = e.pageX;
    window.y = e.pageY;
});

function show_popup(str) {
    $("#popup_content").html(str);
    $("#popup").fadeIn("fast");
    $("#popup").css("top", y);
    $("#popup").css("left", x);
}

In this way I'll always have the distance from the top saved in y and the distance from the left saved in x.

Try:

psql -U role_name -d database -h hostname..com -W

but select-String doesn't seem to have this option.

Correct. PowerShell is not a clone of *nix shells' toolset.

However it is not hard to build something like it yourself:

$regexes = Get-Content RegexFile.txt | 
           Foreach-Object { new-object System.Text.RegularExpressions.Regex $_ }

$fileList | Get-Content | Where-Object {
  foreach ($r in $regexes) {
    if ($r.IsMatch($_)) {
      $true
      break
    }
  }
  $false
}

If the Node is not just any node, but actually an Element (it could also be e.g. an attribute or a text node), you can cast it to Element and use getElementsByTagName.

cd to the repository then

find . -name ".git*" -exec rm -R {} \;

Make sure not to accidentally pipe a single dot, slash, asterisk, or other regex wildcard into find, or else rm will happily delete it.

The example by user11617 is incorrect; it will report that the file exists even in cases where it does not, but there was an error of some other sort.

The signature should be Exists(string) (bool, error). And then, as it happens, the call sites are no better.

The code he wrote would better as:

func Exists(name string) bool {
    _, err := os.Stat(name)
    return !os.IsNotExist(err)
}

But I suggest this instead:

func Exists(name string) (bool, error) {
  _, err := os.Stat(name)
  if os.IsNotExist(err) {
    return false, nil
  }
  return err != nil, err
}

In Bash and zsh you can do this with Brace Expansion. This simply expands a list of items in braces. For example:

# echo {vanilla,chocolate,strawberry}-ice-cream
vanilla-ice-cream chocolate-ice-cream strawberry-ice-cream

So you can do your rename as follows:

mv {,new.}original.filename

as this expands to:

mv original.filename new.original.filename

public static final String URL = "jdbc:sqlserver://localhost:1433;databaseName=dbName";
public static final String USERNAME = "xxxx";
public static final String PASSWORD = "xxxx";

/**
 *  This method
    @param args     command line argument
*/
public static void main(String[] args)
{
   try
   {
        Connection connection;
        DriverManager.registerDriver(new com.microsoft.sqlserver.jdbc.SQLServerDriver());   
        connection = DriverManager.getConnection(MainDriver.URL,MainDriver.USERNAME,
                        MainDriver.PASSWORD);
        String query ="select * from employee";
        Statement statement = connection.createStatement();
        ResultSet resultSet = statement.executeQuery(query);
        while(resultSet.next())
        {
            System.out.print("First Name: " + resultSet.getString("first_name"));
            System.out.println("  Last Name: " + resultSet.getString("last_name"));                
        }
   }catch(Exception ex)
   {
        ex.printStackTrace();
   }
}

Actually, I had this problem same as you. You can get the "Forbidden" error if your commit includes different directories ; Like external items.

And i solved in one step. Just commit external items in another case.

Additionally, I advise you to read articles on External Items in Subversion and VisualSVN Server:

VisualSVN Team's article about Daily Use Guide External Items. It explains the principles of External Items in SVN.

https://tortoisesvn.net/docs/release/TortoiseSVN_en/tsvn-dug-externals.html

By chance: Default error pages often contain detailed information, e.g.

Apache/{Version} ({OS}) {Modules} PHP/{Version} {Modules} Server at {Domain}

Not so easy: Find out which versions of PHP applications run on the server and which version of PHP they require.

Another approach, only mentioned for the sake of completeness; please forget after reading: You could (but you won't!) detect the PHP version by trying known exploits.

If none of the options in the select have a selected attribute, the first option will be the one selected.

In order to select a default option that is not the first, add a selected attribute to that option:

<option selected="selected">Select a language</option>

You can read the HTML 4.01 spec regarding defaults in select element.

I suggest reading a good HTML book if you need to learn HTML basics like this - I recommend Head First HTML.

You can use the File.WriteAllText method.

System.IO.File.WriteAllText(@"Path/foo.bar",string.Empty);

You could use the [DataType] attribute on your view model like this:

public class MyViewModel
{
    [DataType(DataType.MultilineText)]
    public string Text { get; set; }
}

and then you could have a controller:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View(new MyViewModel());
    }
}

and a view which does what you want:

@model AppName.Models.MyViewModel
@using (Html.BeginForm())
{
    @Html.EditorFor(x => x.Text)
    <input type="submit" value="OK" />
}

I verified that chcon -Rt svirt_sandbox_file_t /path/to/volume does work and you don't have to run as a privileged container.

This is on:

• Docker version 0.11.1-dev, build 02d20af/0.11.1
• CentOS 7 as the host and container with SELinux enabled.

I had the same problem. I followed the steps to change the icon but it always installed the default icon.

FIX: After I did the above, I rebuilt the solution by going to build on the Visual Studio menu bar and clicking on 'rebuild solution' and it worked!

A BufferedReader constructor takes a reader as argument, not an InputStream. You should first create a Reader from your stream, like so:

Reader reader = new InputStreamReader(is);
BufferedReader br = new BufferedReader(reader);

Preferrably, you also provide a Charset or character encoding name to the StreamReader constructor. Since a stream just provides bytes, converting these to text means the encoding must be known. If you don't specify it, the system default is assumed.

Back in the old days of Python, to call a function with arbitrary arguments, you would use apply:

apply(f,args,kwargs)

apply still exists in Python2.7 though not in Python3, and is generally not used anymore. Nowadays,

f(*args,**kwargs)

is preferred. The multiprocessing.Pool modules tries to provide a similar interface.

Pool.apply is like Python apply, except that the function call is performed in a separate process. Pool.apply blocks until the function is completed.

Pool.apply_async is also like Python's built-in apply, except that the call returns immediately instead of waiting for the result. An AsyncResult object is returned. You call its get() method to retrieve the result of the function call. The get() method blocks until the function is completed. Thus, pool.apply(func, args, kwargs) is equivalent to pool.apply_async(func, args, kwargs).get().

In contrast to Pool.apply, the Pool.apply_async method also has a callback which, if supplied, is called when the function is complete. This can be used instead of calling get().

For example:

import multiprocessing as mp
import time

def foo_pool(x):
    time.sleep(2)
    return x*x

result_list = []
def log_result(result):
    # This is called whenever foo_pool(i) returns a result.
    # result_list is modified only by the main process, not the pool workers.
    result_list.append(result)

def apply_async_with_callback():
    pool = mp.Pool()
    for i in range(10):
        pool.apply_async(foo_pool, args = (i, ), callback = log_result)
    pool.close()
    pool.join()
    print(result_list)

if __name__ == '__main__':
    apply_async_with_callback()

may yield a result such as

[1, 0, 4, 9, 25, 16, 49, 36, 81, 64]

Notice, unlike pool.map, the order of the results may not correspond to the order in which the pool.apply_async calls were made.

So, if you need to run a function in a separate process, but want the current process to block until that function returns, use Pool.apply. Like Pool.apply, Pool.map blocks until the complete result is returned.

If you want the Pool of worker processes to perform many function calls asynchronously, use Pool.apply_async. The order of the results is not guaranteed to be the same as the order of the calls to Pool.apply_async.

Notice also that you could call a number of different functions with Pool.apply_async (not all calls need to use the same function).

In contrast, Pool.map applies the same function to many arguments. However, unlike Pool.apply_async, the results are returned in an order corresponding to the order of the arguments.

There is no TCP API that will tell you the current state of the connection. isConnected() and isClosed() tell you the current state of your socket. Not the same thing.

1. isConnected() tells you whether you have connected this socket. You have, so it returns true.

2. isClosed() tells you whether you have closed this socket. Until you have, it returns false.

3. If the peer has closed the connection in an orderly way

   • read() returns -1
   • readLine() returns null

   • readXXX() throws EOFException for any other XXX.

   • A write will throw an IOException: 'connection reset by peer', eventually, subject to buffering delays.

4. If the connection has dropped for any other reason, a write will throw an IOException, eventually, as above, and a read may do the same thing.

5. If the peer is still connected but not using the connection, a read timeout can be used.

6. Contrary to what you may read elsewhere, ClosedChannelException doesn't tell you this. [Neither does SocketException: socket closed.] It only tells you that you closed the channel, and then continued to use it. In other words, a programming error on your part. It does not indicate a closed connection.

7. As a result of some experiments with Java 7 on Windows XP it also appears that if:

   • you're selecting on OP_READ
   • select() returns a value of greater than zero
   • the associated SelectionKey is already invalid (key.isValid() == false)

   it means the peer has reset the connection. However this may be peculiar to either the JRE version or platform.

It sounds indeed like video streaming more than image streaming, as someone suggested. JPEG/PNG compression isn't targeted for these types of speeds, so forget them.

Imagine having a recording codec on your system that can realtime record an incoming video stream (your screen). A bit like Fraps perhaps. Then imagine a video playback codec on the other side (the remote client). As HD recorders can do it (record live and even playback live from the same HD), so should you, in the end. The HD surely can't deliver images quicker than you can read your display, so that isn't the bottleneck. The bottleneck are the video codecs. You'll find the encoder much more of a problem than the decoder, as all decoders are mostly free.

I'm not saying it's simple; I myself have used DirectShow to encode a video file, and it's not realtime by far. But given the right codec I'm convinced it can work.

Replace that line with:

$("#someElement").click(function() {
    window.location.href = window.location.href;
});

or:

$("#someElement").click(function() {
    window.location.reload();
});

In VS - project properties - in the Build tab - platform target =X86

et.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {

            et.setHint(temp +" Characters");
        }
    });

You can use Path.Combine with the "base" path, then GetFullPath on the results.

string absPathContainingHrefs = GetAbsolutePath(); // Get the "base" path
string fullPath = Path.Combine(absPathContainingHrefs, @"..\..\images\image.jpg");
fullPath = Path.GetFullPath(fullPath);  // Will turn the above into a proper abs path

First of all, the easiest way to run things at startup is to add them to the file /etc/rc.local.

Another simple way is to use @reboot in your crontab. Read the cron manpage for details.

However, if you want to do things properly, in addition to adding a script to /etc/init.d you need to tell ubuntu when the script should be run and with what parameters. This is done with the command update-rc.d which creates a symlink from some of the /etc/rc* directories to your script. So, you'd need to do something like:

update-rc.d yourscriptname start 2

However, real init scripts should be able to handle a variety of command line options and otherwise integrate to the startup process. The file /etc/init.d/README has some details and further pointers.

>>> import random
>>> d = dict(Venezuela = 1, Spain = 2, USA = 3, Italy = 4)
>>> random.choice(d.keys())
'Venezuela'
>>> random.choice(d.keys())
'USA'

By calling random.choice on the keys of the dictionary (the countries).

You can try the following code to convert the image to hex string

<?php
$image = 'sample.bmp';
$file = fopen($image, 'r') or die("Could not open $image");
while ($file && !feof($file)){
$chunk = fread($file, 1000000); # You can affect performance altering
this number. YMMV.
# This loop will be dog-slow, almost for sure...
# You could snag two or three bytes and shift/add them,
# but at 4 bytes, you violate the 7fffffff limit of dechex...
# You could maybe write a better dechex that would accept multiple bytes
# and use substr... Maybe.
for ($byte = 0; $byte < strlen($chunk); $byte++)){
echo dechex(ord($chunk[$byte]));
}
}
?>

#fullDiv {
    height: 100%;
    width: 100%;
    left: 0;
    top: 0;
    overflow: hidden;
    position: fixed;
}

This should work

top5 = array[:5] 

If your app use multiple webview you will still have troubles : localStorage is not correctly shared accross all webviews.

If you want to share the same data in multiple webviews the only way is to repair it with a java database and a javascript interface.

This page on github shows how to do this.

hope this help!

With ES6 you can write this:

const countries = ['United States', 'Canada', 'Argentina', 'Armenia'];

const $ul = $('<ul>', { class: "mylist" }).append(
  countries.map(country => 
    $("<li>").append($("<a>").text(country))
  )
);

You need to hook to console exit event and not your process.

EDIT

To avoid this error : The specified type member 'Date' is not supported in LINQ to Entities. Only initializers, entity members, and entity navigation properties are supported.

var _My_ResetSet_Array = _DB
                .tbl_MyTable
                .Where(x => x.Active == true)
                         .Select(x => x).ToList();

 var filterdata = _My_ResetSet_Array
        .Where(x=>DateTime.Compare(x.DateTimeValueColumn.Date, DateTime.Now.Date)  <= 0 );

The second line is required because LINQ to Entity is not able to convert date property to sql query. So its better to first fetch the data and then apply the date filter.

EDIT

If you just want to compare the date value of the date time than make use of

DateTime.Date Property - Gets the date component of this instance.

Code for you

var _My_ResetSet_Array = _DB
                .tbl_MyTable
                .Where(x => x.Active == true
     && DateTime.Compare(x.DateTimeValueColumn.Date, DateTime.Now.Date)  <= 0 )
                         .Select(x => x);

If its like that then use

DateTime.Compare Method - Compares two instances of DateTime and returns an integer that indicates whether the first instance is earlier than, the same as, or later than the second instance.

Code for you

var _My_ResetSet_Array = _DB
                .tbl_MyTable
                .Where(x => x.Active == true
                  && DateTime.Compare(x.DateTimeValueColumn, DateTime.Now)  <= 0 )
                         .Select(x => x);

Example

DateTime date1 = new DateTime(2009, 8, 1, 0, 0, 0);
DateTime date2 = new DateTime(2009, 8, 1, 12, 0, 0);
int result = DateTime.Compare(date1, date2);
string relationship;

if (result < 0)
   relationship = "is earlier than";
else if (result == 0)
   relationship = "is the same time as";         
else
   relationship = "is later than";

If you want to manually count it, the size of a struct is just the size of each of its data members after accounting for alignment. There's no magic overhead bytes for a struct.

    button.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View view) {
            //to prevent double click
            button.setOnClickListener(null);
        }
    });

Masking means to keep/change/remove a desired part of information. Lets see an image-masking operation; like- this masking operation is removing any thing that is not skin-

We are doing AND operation in this example. There are also other masking operators- OR, XOR.

Bit-Masking means imposing mask over bits. Here is a bit-masking with AND-

     1 1 1 0 1 1 0 1   [input]
(&)  0 0 1 1 1 1 0 0    [mask]
------------------------------
     0 0 1 0 1 1 0 0  [output]

So, only the middle 4 bits (as these bits are 1 in this mask) remain.

Lets see this with XOR-

     1 1 1 0 1 1 0 1   [input]
(^)  0 0 1 1 1 1 0 0    [mask]
------------------------------
     1 1 0 1 0 0 0 1  [output]

Now, the middle 4 bits are flipped (1 became 0, 0 became 1).

So, using bit-mask we can access individual bits [examples]. Sometimes, this technique may also be used for improving performance. Take this for example-

bool isOdd(int i) {
    return i%2;
}

This function tells if an integer is odd/even. We can achieve the same result with more efficiency using bit-mask-

bool isOdd(int i) {
    return i&1;
}

Short Explanation: If the least significant bit of a binary number is 1 then it is odd; for 0 it will be even. So, by doing AND with 1 we are removing all other bits except for the least significant bit i.e.:

     55  ->  0 0 1 1 0 1 1 1   [input]
(&)   1  ->  0 0 0 0 0 0 0 1    [mask]
---------------------------------------
      1  <-  0 0 0 0 0 0 0 1  [output]

It indeed may be useful for some debug or demonstration needs.

I found that Bob Copeland solution http://bobcopeland.com/blog/2012/10/goto-in-bash/ elegant:

#!/bin/bash
# include this boilerplate
function jumpto
{
    label=$1
    cmd=$(sed -n "/$label:/{:a;n;p;ba};" $0 | grep -v ':$')
    eval "$cmd"
    exit
}

start=${1:-"start"}

jumpto $start

start:
# your script goes here...
x=100
jumpto foo

mid:
x=101
echo "This is not printed!"

foo:
x=${x:-10}
echo x is $x

results in:

$ ./test.sh
x is 100
$ ./test.sh foo
x is 10
$ ./test.sh mid
This is not printed!
x is 101

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

Be carefull that the page does not contain any empty component which has "required" attribute as "true" before your selectOneMenu component running.
If you use a component such as

<p:inputText label="Nm:" id="id_name" value="#{ myHelper.name}" required="true"/>

then,

<p:selectOneMenu .....></p:selectOneMenu>

and forget to fill the required component, ajax listener of selectoneMenu cannot be executed.

There's no such thing as a "localhost" folder; the word "localhost" is an alias for your local computer. The document root for your apache server, by default, is "Sites" in your home directory.

This should do it for you - all your files will end up called Part1-Part500.

#!/bin/bash
FILENAME=10000.csv
HDR=$(head -1 $FILENAME)   # Pick up CSV header line to apply to each file
split -l 20 $FILENAME xyz  # Split the file into chunks of 20 lines each
n=1
for f in xyz*              # Go through all newly created chunks
do
   echo $HDR > Part${n}    # Write out header to new file called "Part(n)"
   cat $f >> Part${n}      # Add in the 20 lines from the "split" command
   rm $f                   # Remove temporary file
   ((n++))                 # Increment name of output part
done

There is also a constructor overload for List that will work... But I guess this would required a strong typed array.

//public List(IEnumerable<T> collection)
var intArray = new[] { 1, 2, 3, 4, 5 };
var list = new List<int>(intArray);

... for Array class

var intArray = Array.CreateInstance(typeof(int), 5);
for (int i = 0; i < 5; i++)
    intArray.SetValue(i, i);
var list = new List<int>((int[])intArray);

For some reason, the accepted answer worked for me only if being used once on the page, but in my case I was trying to save data on many elements on the page and the data was somehow lost on all except the first element.

As an alternative, I ended up writing the data out to the dom and parsing it back in when needed. Perhaps it's less efficient, but worked well for my purpose because I'm really prototyping data and not writing this for production.

To save the data I used:

$('#myElement').attr('data-key', JSON.stringify(jsonObject));

To then read the data back is the same as the accepted answer, namely:

var getBackMyJSON = $('#myElement').data('key');

Doing it this way also made the data appear in the dom if I were to inspect the element with Chrome's debugger.

do it like this:

"abc%s" % 9
#or
"abc" + str(9)

When you write x = 0, x is an int...so you can't do x[age1] because x is int

If you're willing to use pandas:

pandas.DataFrame({'x':hist[1][1:],'y':hist[0]}).plot(x='x',kind='bar')

To get all container names and their IP addresses in just one single command.

docker inspect -f '{{.Name}} - {{.NetworkSettings.IPAddress }}' $(docker ps -aq)

If you are using docker-compose the command will be this:

docker inspect -f '{{.Name}} - {{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' $(docker ps -aq)

The output will be:

/containerA - 172.17.0.4
/containerB - 172.17.0.3
/containerC - 172.17.0.2

Using LIKE will give you options for defining what the rest of the string should look like, but if the rule is just starts with 'NoHist_' it doesn't really matter.

You will get useful information from here.

SELECT ticker

The following example shows the usage of the exit() function.

#include <stdio.h>
#include <stdlib.h>

int main(void) {
    printf("Start of the program....\n");
    printf("Exiting the program....\n");
    exit(0);
    printf("End of the program....\n");
    return 0;
}

Output

Start of the program....
Exiting the program....

You can do that by simply adding new elements to the array with the help of the push() method.

let colors = ["Red", "Blue", "Orange"];
console.log('Array before push: ' + colors);
// append new value to the array
colors.push("Green");
console.log('Array after push : ' + colors);

Another method is used for appending an element to the beginning of an array is the unshift() function, which adds and returns the new length. It accepts multiple arguments, attaches the indexes of existing elements, and finally returns the new length of an array:

let colors = ["Red", "Blue", "Orange"];
console.log('Array before unshift: ' + colors);
// append new value to the array
colors.unshift("Black", "Green");
console.log('Array after unshift : ' + colors);

There are other methods too. You can check them out here.

Below are the steps you can try it out to resolve the issue: -

1. Provide reference of AppCompat Library into your project.
2. If option 1 doesn't solve the issue then you can try to change the style.xml file to below code.

 parent="android:Theme.Holo.Light"  

instead.

 parent="android:Theme.AppCompat.Light"  

But option 2 will require minimum sdk version 14.

Hope this will help !

jQuery API specifically says not to bind to beforeunload, and instead should bind directly to the window.onbeforeunload, I just ran across a pretty bad memory in part due binding to beforeunload with jQuery.

I used exe4j to package all java jars into one final .exe file, which user can use it as normal windows application.

In PHP 7.0.1, I was able to define this:

public static $kIdsByActions = array(
  MyClass1::kAction => 0,
  MyClass2::kAction => 1
);

And then use it like this:

MyClass::$kIdsByActions[$this->mAction];

I am not 100% sure what the conditions are for this, but for me the above didn't work directly, thought it got close. I think it was because I needed "id" for my view by in the model it was called "ObjectID".

I had a model with a variety of pieces of information. I just needed the id.

Before the above I created a new System.Web.Routing.RouteValueDictionary object and added the needed id.

(System.Web.Routing.)RouteValueDictionary RouteInfo = new RouteValueDictionary();
RouteInfo.Add("id", ObjectID);
return RedirectToAction("details", RouteInfo);

(Note: the MVC project in question I didn't create, so I don't know where all the right "fiddly" bits are.)

Google introduced In-app updates lib, (https://developer.android.com/guide/app-bundle/in-app-updates) it works on Lollipop+ and gives you the ability to ask the user for an update with a nice dialog (FLEXIBLE) or with mandatory full-screen message (IMMEDIATE).

You need to implement the latter. Here is how it will look like:

I covered all the code in this answer: https://stackoverflow.com/a/56808529/5502121

Primarily because the result of a someString.join() is a string.

The sequence (list or tuple or whatever) doesn't appear in the result, just a string. Because the result is a string, it makes sense as a method of a string.

In my case I was getting this error because the option (HttpActivation) was not enabled.

To initialize a static variable, you just do so inside of a source file. For example:

//Foo.h
class Foo
{
 private:
  static int hello;
};


//Foo.cpp
int Foo::hello = 1;

You also have to modify the minimum size of the data and log files. DBCC SHRINKDATABASE will shrink the data inside the files you already have allocated. To shrink a file to a size smaller than its minimum size, use DBCC SHRINKFILE and specify the new size.

$date = mysql_real_escape_string($_POST['intake_date']);

1. If your MySQL column is DATE type:

$date = date('Y-m-d', strtotime(str_replace('-', '/', $date)));

2. If your MySQL column is DATETIME type:

$date = date('Y-m-d H:i:s', strtotime(str_replace('-', '/', $date)));

You haven't got to work strototime(), because it will not work with dash - separators, it will try to do a subtraction.

Update, the way your date is formatted you can't use strtotime(), use this code instead:

$date = '02/07/2009 00:07:00';
$date = preg_replace('#(\d{2})/(\d{2})/(\d{4})\s(.*)#', '$3-$2-$1 $4', $date);
echo $date;

Output:

From the UIDevice class:

As an example: [[UIDevice currentDevice] name];

The UIDevice is a class that provides information about the iPhone or iPod Touch device.

Some of the information provided by UIDevice is static, such as device name or system version.

In C it was a nice way to implement something like an variant.

enum possibleTypes{
  eInt,
  eDouble,
  eChar
}


struct Value{

    union Value {
      int iVal_;
      double dval;
      char cVal;
    } value_;
    possibleTypes discriminator_;
} 

switch(val.discriminator_)
{
  case eInt: val.value_.iVal_; break;

In times of litlle memory this structure is using less memory than a struct that has all the member.

By the way C provides

    typedef struct {
      unsigned int mantissa_low:32;      //mantissa
      unsigned int mantissa_high:20;
      unsigned int exponent:11;         //exponent
      unsigned int sign:1;
    } realVal;

to access bit values.

Is this role attribute necessary?

Answer: Yes.

• The role attribute is necessary to support Accessible Rich Internet Applications (WAI-ARIA) to define roles in XML-based languages, when the languages do not define their own role attribute.
• Although this is the reason the role attribute is published by the Protocols and Formats Working Group, the attribute has more general use cases as well.

It provides you:

• Accessibility
• Device adaptation
• Server-side processing
• Complex data description,...etc.

This commands deletes all your queues

python rabbitmqadmin.py \
  -H YOURHOST -u guest -p guest -f bash list queues | \
xargs -n1 | \
xargs -I{} \
  python rabbitmqadmin.py -H YOURHOST -u guest -p guest delete queue name={}

This script is super simple because it uses -f bash, which outputs the queues as a list.

Then we use xargs -n1 to split that up into multiple variables

Then we use xargs -I{} that will run the command following, and replace {} in the command.

If the comment message includes non-English characters, using method provided by user456814, those characters will be replaced by question marks. (tested under sourcetree Ver2.5.5.0)

So I have to use the following method.

CAUTION: if the commit has been pulled by other members, changes below might cause chaos for them.

Step1: In the sourcetree main window, locate your repo tab, and click the "terminal" button to open the git command console.

Step2:

[Situation A]: target commit is the latest one.

1) In the git command console, input

git commit --amend -m "new comment message"

2) If the target commit has been pushed to remote, you have to push again by force. In the git command console, input

git push --force

[Situation B]: target commit is not the latest one.

1) In the git command console, input

git rebase -i HEAD~n

It is to squash the latest n commits. e.g. if you want to edit the message before the last one, n is 2. This command will open a vi window, the first word of each line is "pick", and you change the "pick" to "reword" for the line you want to edit. Then, input :wq to save&quit that vi window. Now, a new vi window will be open, in this window you input your new message. Also use :wq to save&quit.

2) If the target commit has been pushed to remote, you have to push again by force. In the git command console, input

git push --force

Finally: In the sourcetree main window, Press F5 to refresh.

Use this one:

implementation 'com.android.support:appcompat-v7:26.0.0-beta1'
implementation 'com.android.support:design:26.0.0-beta1'

instead of

implementation 'com.android.support:appcompat-v7:26.0.0-beta2'
implementation 'com.android.support:design:26.0.0-beta2'

In my case it removed the rendering problem.

if you want to connect with oracle database

1. open sql prompt
2. connect with sysdba for XE- conn / as sysdba for IE- conn sys as sysdba
3. then start up database by below command startup;

once it get start means you can access oracle database now. if you want connect another user you can write conn username/password e.g. conn scott/tiger; it will show connected........

So I had this exact same issue and lost about 6 hours of my life searching, I had the

withCredentials: true

But the browser still didn't save the cookie until for some weird reason I had the idea to shuffle the configuration setting:

Axios.post(GlobalVariables.API_URL + 'api/login', {
        email,
        password,
        honeyPot
    }, {
        withCredentials: true,
        headers: {'Access-Control-Allow-Origin': '*', 'Content-Type': 'application/json'
    }});

Seems like you should always send the 'withCredentials' Key first.

The ztime() function is the main logic you need — it gets the current time and stores it in a 64bit uint measured in microseconds. You can then later do simple math to find out the elapsed time.

The ZenTimer*() functions are just helper functions to take a pointer to a simple timer struct, ztimer_t, which records the start time and the end time. The ZenTimerPause()/ZenTimerResume() functions allow you to, well, pause and resume the timer in case you want to print out some debugging information that you don't want timed, for example.

You can find a copy of the original header file at http://www.gnome.org/~fejj/code/zentimer.h in the off chance that I messed up the html escaping of <'s or something. It's licensed under MIT/X11 so feel free to copy it into any project you do.

Whenever I talk managed vs. unmanaged performance, I like to point to the series Rico (and Raymond) did comparing C++ and C# versions of a Chinese/English dictionary. This google search will let you read for yourself, but I like Rico's summary.

So am I ashamed by my crushing defeat? Hardly. The managed code got a very good result for hardly any effort. To defeat the managed Raymond had to:

• Write his own file I/O stuff
• Write his own string class
• Write his own allocator
• Write his own international mapping

Of course he used available lower level libraries to do this, but that's still a lot of work. Can you call what's left an STL program? I don't think so, I think he kept the std::vector class which ultimately was never a problem and he kept the find function. Pretty much everything else is gone.

So, yup, you can definately beat the CLR. Raymond can make his program go even faster I think.

Interestingly, the time to parse the file as reported by both programs internal timers is about the same -- 30ms for each. The difference is in the overhead.

For me the bottom line is that it took 6 revisions for the unmanaged version to beat the managed version that was a simple port of the original unmanaged code. If you need every last bit of performance (and have the time and expertise to get it), you'll have to go unmanaged, but for me, I'll take the order of magnitude advantage I have on the first versions over the 33% I gain if I try 6 times.

Updated code:

This is purported to work officially.

#if TARGET_IPHONE_SIMULATOR
NSString *hello = @"Hello, iPhone simulator!";
#elif TARGET_OS_IPHONE
NSString *hello = @"Hello, device!";
#else
NSString *hello = @"Hello, unknown target!";
#endif

Original post (since deprecated)

This code will tell you if you are running in a simulator.

#ifdef __i386__
NSLog(@"Running in the simulator");
#else
NSLog(@"Running on a device");
#endif

__VA_ARGS__ is the standard way to do it. Don't use compiler-specific hacks if you don't have to.

I'm really annoyed that I can't comment on the original post. In any case, C++ is not a superset of C. It is really silly to compile your C code with a C++ compiler. Don't do what Donny Don't does.

a bit late, but it might be worth checking the "indicator" parameter of pd.merge.

See this other question for an example: Compare PandaS DataFrames and return rows that are missing from the first one

You can do it via ssh.

ssh [email protected] "python ./hello.py"

You can also edit the script in ssh using a textual editor or X11 forwarding.

Kotlin Solution :

private fun locationEnabled() : Boolean {
    val locationManager = getSystemService(Context.LOCATION_SERVICE) as LocationManager
    return locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)
}

Assuming:

1. You have 2's-complement representations in mind; and,
2. By (unsigned long) you mean unsigned 32-bit integer,

then you just need to add 2**32 (or 1 << 32) to the negative value.

For example, apply this to -1:

>>> -1
-1
>>> _ + 2**32
4294967295L
>>> bin(_)
'0b11111111111111111111111111111111'

Assumption #1 means you want -1 to be viewed as a solid string of 1 bits, and assumption #2 means you want 32 of them.

Nobody but you can say what your hidden assumptions are, though. If, for example, you have 1's-complement representations in mind, then you need to apply the ~ prefix operator instead. Python integers work hard to give the illusion of using an infinitely wide 2's complement representation (like regular 2's complement, but with an infinite number of "sign bits").

And to duplicate what the platform C compiler does, you can use the ctypes module:

>>> import ctypes
>>> ctypes.c_ulong(-1)  # stuff Python's -1 into a C unsigned long
c_ulong(4294967295L)
>>> _.value
4294967295L

C's unsigned long happens to be 4 bytes on the box that ran this sample.

Actually this error occurs when server makes connection but can't build due to failure in identifying connection function identifier. This problem can be solved by typing connection function in code. For this I take a simple example. In this case function is con your may be different.

SqlCommand cmd = new SqlCommand("insert into ptb(pword,rpword) values(@a,@b)",con);

C++ has no built-in concepts of interfaces. You can implement it using abstract classes which contains only pure virtual functions. Since it allows multiple inheritance, you can inherit this class to create another class which will then contain this interface (I mean, object interface :) ) in it.

An example would be something like this -

class Interface
{
public:
    Interface(){}
    virtual ~Interface(){}
    virtual void method1() = 0;    // "= 0" part makes this method pure virtual, and
                                   // also makes this class abstract.
    virtual void method2() = 0;
};

class Concrete : public Interface
{
private:
    int myMember;

public:
    Concrete(){}
    ~Concrete(){}
    void method1();
    void method2();
};

// Provide implementation for the first method
void Concrete::method1()
{
    // Your implementation
}

// Provide implementation for the second method
void Concrete::method2()
{
    // Your implementation
}

int main(void)
{
    Interface *f = new Concrete();

    f->method1();
    f->method2();

    delete f;

    return 0;
}

Building on @ShadowCloud 's example I was able to dynamically include all routes in a sub directory.

routes/index.js

var fs = require('fs');

module.exports = function(app){
    fs.readdirSync(__dirname).forEach(function(file) {
        if (file == "index.js") return;
        var name = file.substr(0, file.indexOf('.'));
        require('./' + name)(app);
    });
}

Then placing route files in the routes directory like so:

routes/test1.js

module.exports = function(app){

    app.get('/test1/', function(req, res){
        //...
    });

    //other routes..
}

Repeating that for as many times as I needed and then finally in app.js placing

require('./routes')(app);

You can add style for :after a like html code.
For example:

var value = 22;
body.append('<style>.wrapper:after{border-top-width: ' + value + 'px;}</style>');

\< means beginning of a word, and \> means the end of a word,

Adding @Roe's comment:
VIM provides a shortcut for this. If you already have word on screen and you want to find other instances of it, you can put the cursor on the word and press '*' to search forward in the file or '#' to search backwards.

There is obviously another process listening on the port. You might find out that process by using the following command:

$ lsof -i :8000

or change your tornado app's port. tornado's error info not Explicitly on this.

First I would like to thank Rose who was willing to help us, but your answer could solve the problem on a computer, but in others there was what was done could not always connect gets error 720. After much searching and contact the Microsoft support we can solve. In Device Manager, on the View menu, select to show hidden devices. Made it look for a remote Miniport IP or network monitor that is with warning of problems with the driver icon. In its properties in the details tab check the Key property of the driver. Look for this key in Regedit on Local Machine, make a backup of that key and delete it. Restart your windows. Reopen your device manager and select the miniport that had deleted the record. Activate the option to update the driver and look for the option driver on the computer manually and then use the option to locate the driver from the list available on the computer on the next screen uncheck show compatible hardware. Then you must select the Microsoft Vendor and the driver WAN Miniport the type that is changing, IP or IPV6 L2TP Network Monitor. After upgrading restart the computer.

I know it's a bit laborious but that was the only way that worked on all computers.

Follow the below steps in Eclipse.

1. Goto -> AVD Manager
2. Create/Edit the AVD.
3. Hardware > New:
4. Configures camera facing back
5. Click on the property value and choose = "webcam0".
6. Once done all the above the webcam should be connected. If it doesnt then you need to check your WebCam drivers.

You shouldn't really be de-encrypting passwords.

You should be encrypting the password entered into your application and comparing against the encrypted password from the database.

Edit - and if this is because the password has been forgotten, then setup a mechanism to create a new password.

I believe fill is the fastest way to do this.

a = np.empty(10)
a.fill(7)

You should also always avoid iterating like you are doing in your example. A simple a[:] = v will accomplish what your iteration does using numpy broadcasting.

Your code seems to be fine, make sure that key you specify really exists in the array or such key has a value in your array eg:

$array = array(4 => 'Hello There');
print_r(array_keys($array));
// or better
print_r($array);

Output:

Array
(
    [0] => 4
)

Now:

$key = 4;
$value = $array[$key];
print $value;

Output:

Hello There

I would suggest that you use a dictionary like so:

arr = {}

arr[1] = (1, 2, 4)
arr[18] = (3, 4, 5)

print(arr[1])
>>> (1, 2, 4)

If you're not sure an entry is defined in the dictionary, you'll need a validation mechanism when calling "arr[x]", e.g. try-except.

I would like to add that the JAVA_OPTS settings are already in run.conf.bat. You just have to uncomment them:

in JBOSS_HOME\bin\run.conf.bat on Windows:

rem # Sample JPDA settings for remote socket debugging
set "JAVA_OPTS=%JAVA_OPTS% -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n"

The Linux version is similar and is located at JBOSS_HOME/bin/run.conf

You are not getting value of $id=$_GET['id'];

And you are using it (before it gets initialised).

Use php's in built isset() function to check whether the variable is defied or not.

So, please update the line to:

$id = isset($_GET['id']) ? $_GET['id'] : '';

            while ((responeLine = bufferedReader.readLine()) != null)
            {

            System.out.println(response);
        }catch(Exception ex){ex.printStackTrace();}

There could also be some filters applied to the console. Remove them.

IllegalStateException signals that method has been invoked at the wrong time. In this below example, we can see that. remove() method is called at the same time element is being used in while loop.

You want to assign something like this to onfocus:

if (this.value == this.defaultValue)
    this.value = ''
this.className = ''

and this to onblur:

if (this.value == '')
    this.value = this.defaultValue
this.className = 'placeholder'

(You can use something a bit cleverer, like a framework function, to do the classname switching if you want.)

With some CSS like this:

input.placeholder{
    color: gray;
    font-style: italic;
}

this is how i did it:

String[] listAges = getResources().getStringArray(R.array.ages);

        // Creating adapter for spinner
        ArrayAdapter<String> dataAdapter =
                new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, listAges);

        // Drop down layout style - list view with radio button
        dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

        // attaching data adapter to spinner
        spinner_age.getBackground().setColorFilter(ContextCompat.getColor(this, R.color.spinner_icon), PorterDuff.Mode.SRC_ATOP);
        spinner_age.setAdapter(dataAdapter);
        spinner_age.setSelection(0);
        spinner_age.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                String item = parent.getItemAtPosition(position).toString();

                if(position > 0){
                    // get spinner value
                    Toast.makeText(parent.getContext(), "Age..." + item, Toast.LENGTH_SHORT).show();
                }else{
                    // show toast select gender
                    Toast.makeText(parent.getContext(), "none" + item, Toast.LENGTH_SHORT).show();
                }
            }
            @Override
            public void onNothingSelected(AdapterView<?> parent) {
            }
        });

I had taken .svn folder from my fellow developer and replaced my .svn folder with this. It worked for me. Don't know what may be other consequences!

CREATE VIEW MyView AS
   SELECT Column, Value FROM Table;


SELECT Column FROM MyView WHERE Value = 1;

Is the proper solution in MySQL, some other SQLs let you define Views more exactly.

Note: Unless the View is very complicated, MySQL will optimize this just fine.

I wrote this for strings AND functionality (I know it's not the question but I searched for it and got here), maybe it can be expanded.

String.prototype.contains = function(str) {
  return this.indexOf(str) != -1;
};

String.prototype.containsAll = function(strArray) {
  for (var i = 0; i < strArray.length; i++) {
    if (!this.contains(strArray[i])) {
      return false;
    }
  }
  return true;
}

app.filter('filterMultiple', function() {
  return function(items, filterDict) {
    return items.filter(function(item) {
      for (filterKey in filterDict) {
        if (filterDict[filterKey] instanceof Array) {
          if (!item[filterKey].containsAll(filterDict[filterKey])) {
            return false;
          }
        } else {
          if (!item[filterKey].contains(filterDict[filterKey])) {
            return false;
          }
        }
      }
      return true;
    });  
  };
});

Usage:

<li ng-repeat="x in array | filterMultiple:{key1: value1, key2:[value21, value22]}">{{x.name}}</li>

For me it worked after I did:

• Cleaning solution.
• Deleting the app from the phone I've debugged it at.
• Closing Visual Studio.
• Deleting folders /bin/ and /obj/ in android projects.
• Launching solution again.

It handle all possible stuff and even reference itself in structure of object. You can see the example at the end of code.

you can use the query options {raw: true} to return the raw result. Your query should like follows:

db.Sensors.findAll({
  where: {
    nodeid: node.nodeid
  },
  raw: true,
})

also if you have associations with include that gets flattened. So, we can use another parameter nest:true

db.Sensors.findAll({
  where: {
    nodeid: node.nodeid
  },
  raw: true,
  nest: true,
})

remove href attribute:

<a id="" onclick="f1()">jhhghj</a>

if link styles are important then:

<a href="javascript:void(f1())">jhhghj</a>

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

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

      }                 
});

I hope this fixes your problem.

Here is what I had and what caused my "incomplete type error":

#include "X.h" // another already declared class
class Big {...} // full declaration of class A

class Small : Big {
    Small() {}
    Small(X); // line 6
}
//.... all other stuff

What I did in the file "Big.cpp", where I declared the A2's constructor with X as a parameter is..

Big.cpp

Small::Big(X my_x) { // line 9 <--- LOOK at this !
}

I wrote "Small::Big" instead of "Small::Small", what a dumb mistake.. I received the error "incomplete type is now allowed" for the class X all the time (in lines 6 and 9), which made a total confusion..

Anyways, that is where a mistake can happen, and the main reason is that I was tired when I wrote it and I needed 2 hours of exploring and rewriting the code to reveal it.

You can simply use

 $(this).prev().val("hello world");

JSFiddle Demo

Detect OS Version:

    public static string OS_Name()
    {
        return (string)(from x in new ManagementObjectSearcher(
            "SELECT Caption FROM Win32_OperatingSystem").Get().Cast<ManagementObject>() 
            select x.GetPropertyValue("Caption")).FirstOrDefault();
    }

Yes, here's an example:

CREATE TABLE myTable ( col1 int, createdDate datetime DEFAULT(getdate()), updatedDate datetime DEFAULT(getdate()) )

You can INSERT into the table without indicating the createdDate and updatedDate columns:

INSERT INTO myTable (col1) VALUES (1)

Or use the keyword DEFAULT:

INSERT INTO myTable (col1, createdDate, updatedDate) VALUES (1, DEFAULT, DEFAULT)

Then create a trigger for updating the updatedDate column:

CREATE TRIGGER dbo.updateMyTable 
ON dbo.myTable
FOR UPDATE 
AS 
BEGIN 
    IF NOT UPDATE(updatedDate) 
        UPDATE dbo.myTable SET updatedDate=GETDATE() 
        WHERE col1 IN (SELECT col1 FROM inserted) 
END 
GO

After lots of research, I've come up with this answer, and I'm hereby putting it here as an answer for my own question, for reference:

1. Make sure that "Enable access for assistive devices" is checked in System Preferences>>Universal Access. It is required for the AppleScript to work. You may have to reboot after this change (it doesn't work otherwise on Mac OS X Server 10.4).

2. Create a R/W DMG. It must be larger than the result will be. In this example, the bash variable "size" contains the size in Kb and the contents of the folder in the "source" bash variable will be copied into the DMG:

   hdiutil create -srcfolder "${source}" -volname "${title}" -fs HFS+ \
         -fsargs "-c c=64,a=16,e=16" -format UDRW -size ${size}k pack.temp.dmg
   

3. Mount the disk image, and store the device name (you might want to use sleep for a few seconds after this operation):

   device=$(hdiutil attach -readwrite -noverify -noautoopen "pack.temp.dmg" | \
            egrep '^/dev/' | sed 1q | awk '{print $1}')
   

4. Store the background picture (in PNG format) in a folder called ".background" in the DMG, and store its name in the "backgroundPictureName" variable.

5. Use AppleScript to set the visual styles (name of .app must be in bash variable "applicationName", use variables for the other properties as needed):

   echo '
      tell application "Finder"
        tell disk "'${title}'"
              open
              set current view of container window to icon view
              set toolbar visible of container window to false
              set statusbar visible of container window to false
              set the bounds of container window to {400, 100, 885, 430}
              set theViewOptions to the icon view options of container window
              set arrangement of theViewOptions to not arranged
              set icon size of theViewOptions to 72
              set background picture of theViewOptions to file ".background:'${backgroundPictureName}'"
              make new alias file at container window to POSIX file "/Applications" with properties {name:"Applications"}
              set position of item "'${applicationName}'" of container window to {100, 100}
              set position of item "Applications" of container window to {375, 100}
              update without registering applications
              delay 5
              close
        end tell
      end tell
   ' | osascript
   

6. Finialize the DMG by setting permissions properly, compressing and releasing it:

   chmod -Rf go-w /Volumes/"${title}"
   sync
   sync
   hdiutil detach ${device}
   hdiutil convert "/pack.temp.dmg" -format UDZO -imagekey zlib-level=9 -o "${finalDMGName}"
   rm -f /pack.temp.dmg 
   

On Snow Leopard, the above applescript will not set the icon position correctly - it seems to be a Snow Leopard bug. One workaround is to simply call close/open after setting the icons, i.e.:

..
set position of item "'${applicationName}'" of container window to {100, 100}
set position of item "Applications" of container window to {375, 100}
close
open

According to the documentation of the Item property:

Sets or returns an item for a specified key in a Dictionary object.

In your case, you don't have an item whose key is 1 so doing:

s = d.Item(i)

actually creates a new key / value pair in your dictionary, and the value is empty because you have not used the optional newItem argument.

The Dictionary also has the Items method which allows looping over the indices:

a = d.Items
For i = 0 To d.Count - 1
    s = a(i)
Next i

The error happens because MySQL can index only the first N chars of a BLOB or TEXT column. So The error mainly happens when there is a field/column type of TEXT or BLOB or those belong to TEXT or BLOB types such as TINYBLOB, MEDIUMBLOB, LONGBLOB, TINYTEXT, MEDIUMTEXT, and LONGTEXT that you try to make a primary key or index. With full BLOB or TEXT without the length value, MySQL is unable to guarantee the uniqueness of the column as it’s of variable and dynamic size. So, when using BLOB or TEXT types as an index, the value of N must be supplied so that MySQL can determine the key length. However, MySQL doesn’t support a key length limit on TEXT or BLOB. TEXT(88) simply won’t work.

The error will also pop up when you try to convert a table column from non-TEXT and non-BLOB type such as VARCHAR and ENUM into TEXT or BLOB type, with the column already been defined as unique constraints or index. The Alter Table SQL command will fail.

The solution to the problem is to remove the TEXT or BLOB column from the index or unique constraint or set another field as primary key. If you can't do that, and wanting to place a limit on the TEXT or BLOB column, try to use VARCHAR type and place a limit of length on it. By default, VARCHAR is limited to a maximum of 255 characters and its limit must be specified implicitly within a bracket right after its declaration, i.e VARCHAR(200) will limit it to 200 characters long only.

Sometimes, even though you don’t use TEXT or BLOB related type in your table, the Error 1170 may also appear. It happens in a situation such as when you specify VARCHAR column as primary key, but wrongly set its length or characters size. VARCHAR can only accepts up to 256 characters, so anything such as VARCHAR(512) will force MySQL to auto-convert the VARCHAR(512) to a SMALLTEXT datatype, which subsequently fails with error 1170 on key length if the column is used as primary key or unique or non-unique index. To solve this problem, specify a figure less than 256 as the size for VARCHAR field.

Reference: MySQL Error 1170 (42000): BLOB/TEXT Column Used in Key Specification Without a Key Length

The <p> paragraph tag is meant for specifying paragraphs of text. If you don't want the text to start on a new line, I would suggest you're using the <p> tag incorrectly. Perhaps the <span> tag more closely fits what you want to achieve...?

For me, it was having display: none;

#spinner-success-text {
    display: none;
    transition: all 1s ease-in;
}

#spinner-success-text.show {
    display: block;
}

Removing it, and using opacity instead, fixed the issue.

#spinner-success-text {
    opacity: 0;
    transition: all 1s ease-in;
}

#spinner-success-text.show {
    opacity: 1;
}

If you set the Ie 'Document Mode' to 'Standards' you can use the simple javascript 'size' method to get the uploaded file's size.

Set the Ie 'Document Mode' to 'Standards':

<meta http-equiv="X-UA-Compatible" content="IE=Edge">

Than, use the 'size' javascript method to get the uploaded file's size:

<script type="text/javascript">
    var uploadedFile = document.getElementById('imageUpload');
    var fileSize = uploadedFile.files[0].size;
    alert(fileSize); 
</script>

It works for me.

If you're on Ubuntu, make sure docker-compose isn't installed as snap. This will cause all kinds of random issues, including the above.

Remove the snap:

sudo snap remove docker-compose

And install manually from compose repository:

If you're trying to get the integers from the command line args, you'll need something like this:

public static void main(String[] args) {
    int[] nums = new int[args.length];
    for(int i = 0; i < args.length; i++) {
        try {
            nums[i] = Integer.parseInt(args[i]);
        }
        catch(NumberFormatException nfe) {
            System.err.println("Invalid argument");
        }
    }

    // averaging code here
}

As for the actual averaging code, others have suggested how you can tweak that (so I won't repeat what they've said).

Edit: actually it's probably better to just put it inside the above loop and not use the nums array at all

Using ASP.Net Post call, this worked for me.

getNewToken.Append("https://www.googleapis.com/oauth2/v4/token");                        
HttpClient client = new HttpClient();
client.BaseAddress = new Uri(getNewToken.ToString());
                    var values = new Dictionary<string, string>
                    {
                        { "client_id", <Your Client Id> },
                        { "client_secret", <Your Client Secret> },
                        { "refresh_token", <Your Saved Refresh Token> },
                        { "grant_type", "refresh_token"}
                    };

                    var content = new FormUrlEncodedContent(values);
                    var response = await client.PostAsync(getNewToken.ToString(), content);

The directory name seems to be case sensitive. I faced the same issue but when I provided the directory name in upper case it worked.

I was facing the same issue. Run Windows PowerShell as Administrator. It resolved my issue.

I've been using this trick for several years and it works perfectly without any problem for checked/unchecked checkbox status while using with PHP and Database.

HTML Code: (for Add Page)

<input name="status" type="checkbox" value="1" checked>

Hint: remove "checkbox" if you want to show it as unchecked by default

HTML Code: (for Edit Page)

<input name="status" type="checkbox" value="1" 
<?php if ($row['status'] == 1) { echo "checked='checked'"; } ?>>

PHP Code: (use for Add/Edit pages)

$status = $_POST['status'];
if ($status == 1) {
$status = 1;
} else {
$status = 0;
}

Hint: There will always be empty value unless user checked it. So, we already have PHP code to catch it else keep the value to 0. Then, simply use the $status variable for database.

You can also do something like this...

<input @input="myHandler('foo', 'bar', ...arguments)">

Evan You himself recommended this technique in one post on Vue forum. In general some events may emit more than one argument. Also as documentation states internal variable $event is meant for passing original DOM event.

Here's a detailed explanation about the calculation of MaxClients and MaxRequestsPerChild

http://web.archive.org/web/20160415001028/http://www.genericarticles.com/mediawiki/index.php?title=How_to_optimize_apache_web_server_for_maximum_concurrent_connections_or_increase_max_clients_in_apache

ServerLimit 16
StartServers 2
MaxClients 200
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25

First of all, whenever an apache is started, it will start 2 child processes which is determined by StartServers parameter. Then each process will start 25 threads determined by ThreadsPerChild parameter so this means 2 process can service only 50 concurrent connections/clients i.e. 25x2=50. Now if more concurrent users comes, then another child process will start, that can service another 25 users. But how many child processes can be started is controlled by ServerLimit parameter, this means that in the configuration above, I can have 16 child processes in total, with each child process can handle 25 thread, in total handling 16x25=400 concurrent users. But if number defined in MaxClients is less which is 200 here, then this means that after 8 child processes, no extra process will start since we have defined an upper cap of MaxClients. This also means that if I set MaxClients to 1000, after 16 child processes and 400 connections, no extra process will start and we cannot service more than 400 concurrent clients even if we have increase the MaxClient parameter. In this case, we need to also increase ServerLimit to 1000/25 i.e. MaxClients/ThreadsPerChild=40 So this is the optmized configuration to server 1000 clients

<IfModule mpm_worker_module>
    ServerLimit          40
    StartServers          2
    MaxClients          1000
    MinSpareThreads      25
    MaxSpareThreads      75 
    ThreadsPerChild      25
    MaxRequestsPerChild   0
</IfModule>

Assuming you're on local branch master, which is tracking origin/master:

git diff --stat origin/master..

• consider a table={cid,sid,location}
• candidate key: cidsid (uniquely identify the row)
• prime attributes: cid and sid (attributes which are used in making of candidate key)
• non-prime attribute: location(attribute other than candidate key)

if candidate key determine non-prime attribute:

i.e cidsid--->location (---->=determining) 
   then, it is fully functional dependent

if proper subset of candidate key determining non-prime attribute:

 i.e sid--->location (proper subset are sid and cid)
         then it is term as partial dependency

to remove partial dependency we divide the table accordingly .

You may use:

• Array.prototype.map()
• Array.prototype.reduce()
• Arrow functions
• Comma operator

To create array of objects:

var source = ['left', 'top'];
const result = source.map(arrValue => ({[arrValue]: 0}));

Demo:

var source = ['left', 'top'];_x000D_
_x000D_
const result = source.map(value => ({[value]: 0}));_x000D_
_x000D_
console.log(result);

Or if you wants to create a single object from values of arrays:

var source = ['left', 'top'];
const result = source.reduce((obj, arrValue) => (obj[arrValue] = 0, obj), {});

Demo:

var source = ['left', 'top'];_x000D_
_x000D_
const result = source.reduce((obj, arrValue) => (obj[arrValue] = 0, obj), {});_x000D_
_x000D_
console.log(result);

First, you may also consider making the process of getting and validating the input a function; within that function, you can just return the value if its correct, and keep spinning in the while loop if not. This essentially obviates the problem you solved, and can usually be applied in the more general case (breaking out of multiple loops). If you absolutely must keep this structure in your code, and really don't want to deal with bookkeeping booleans...

You may also use goto in the following way (using an April Fools module from here):

#import the stuff
from goto import goto, label

while True:
    #snip: print out current state
    while True:
        ok = get_input("Is this ok? (y/n)")
        if ok == "y" or ok == "Y": goto .breakall
        if ok == "n" or ok == "N": break
    #do more processing with menus and stuff
label .breakall

I know, I know, "thou shalt not use goto" and all that, but it works well in strange cases like this.

Hint: To convert an NSArray containing JSON compatible objects to an NSData object containing a JSON document, use the appropriate method of NSJSONSerialization. JSONObjectWithData is not it.

Hint 2: You rarely want that data as a string; only for debugging purposes.

This solves my problem.

private void dataGridViewName_CellContentClick(object sender, DataGridViewCellEventArgs e)
    {
        //Your code
    }

Thanks to @Pax Diablo, @bvmou and @Arachnid for the suggestion of using full datetimes throughout. If I have to accept datetime.time objects from an external source, then this seems to be an alternative add_secs_to_time() function:

def add_secs_to_time(timeval, secs_to_add):
    dummy_date = datetime.date(1, 1, 1)
    full_datetime = datetime.datetime.combine(dummy_date, timeval)
    added_datetime = full_datetime + datetime.timedelta(seconds=secs_to_add)
    return added_datetime.time()

This verbose code can be compressed to this one-liner:

(datetime.datetime.combine(datetime.date(1, 1, 1), timeval) + datetime.timedelta(seconds=secs_to_add)).time()

but I think I'd want to wrap that up in a function for code clarity anyway.

You have your slash backwards, it should be "\n"

Change your black and white IDs to classes instead (duplicate IDs are invalid), add 2 buttons with the proper IDs, and do this:

var rows = $('table.someclass tr');

$('#showBlackButton').click(function() {
    var black = rows.filter('.black').show();
    rows.not( black ).hide();
});

$('#showWhiteButton').click(function() {
    var white = rows.filter('.white').show();
    rows.not( white ).hide();
});

$('#showAll').click(function() {
    rows.show();
});

<button id="showBlackButton">show black</button>
<button id="showWhiteButton">show white</button>
<button id="showAll">show all</button>

<table class="someclass" border="0" cellpadding="0" cellspacing="0" summary="bla bla bla">
    <caption>bla bla bla</caption>
    <thead>
          <tr class="black">
            ...
          </tr>
    </thead>
    <tbody>
        <tr class="white">
            ...
        </tr>
        <tr class="black">
           ...
        </tr>
    </tbody>
</table>

It uses the filter()^[docs] method to filter the rows with the black or white class (depending on the button).

Then it uses the not()^[docs] method to do the opposite filter, excluding the black or white rows that were previously found.

EDIT: You could also pass a selector to .not() instead of the previously found set. It may perform better that way:

rows.not( `.black` ).hide();

// ...

rows.not( `.white` ).hide();

...or better yet, just keep a cached set of both right from the start:

var rows = $('table.someclass tr');
var black = rows.filter('.black');
var white = rows.filter('.white');

$('#showBlackButton').click(function() {
    black.show();
    white.hide();
});

$('#showWhiteButton').click(function() {
    white.show();
    black.hide();
});

hashCode() method is not for providing a unique identifier for an object. It rather digests the object's state (i.e. values of member fields) to a single integer. This value is mostly used by some hash based data structures like maps and sets to effectively store and retrieve objects.

If you need an identifier for your objects, I recommend you to add your own method instead of overriding hashCode. For this purpose, you can create a base interface (or an abstract class) like below.

public interface IdentifiedObject<I> {
    I getId();
}

Example usage:

public class User implements IdentifiedObject<Integer> {
    private Integer studentId;

    public User(Integer studentId) {
        this.studentId = studentId;
    }

    @Override
    public Integer getId() {
        return studentId;
    }
}

As per Xenon's comment to Anil Özselgin's answer, anonymous classes have been implemented in PHP 7.0, which is as close to nested classes as you'll get right now. Here are the relevant RFCs:

Nested Classes (status: withdrawn)

Anonymous Classes (status: implemented in PHP 7.0)

An example to the original post, this is what your code would look like:

<?php
    public class User {
        public $userid;
        public $username;
        private $password;

        public $profile;
        public $history;

        public function __construct() {
            $this->profile = new class {
                // Some code here for user profile
            }

            $this->history = new class {
                // Some code here for user history
            }
        }
    }
?>

This, though, comes with a very nasty caveat. If you use an IDE such as PHPStorm or NetBeans, and then add a method like this to the User class:

public function foo() {
  $this->profile->...
}

...bye bye auto-completion. This is the case even if you code to interfaces (the I in SOLID), using a pattern like this:

<?php
    public class User {
        public $profile;

        public function __construct() {
            $this->profile = new class implements UserProfileInterface {
                // Some code here for user profile
            }
        }
    }
?>

Unless your only calls to $this->profile are from the __construct() method (or whatever method $this->profile is defined in) then you won't get any sort of type hinting. Your property is essentially "hidden" to your IDE, making life very hard if you rely on your IDE for auto-completion, code smell sniffing, and refactoring.

In my case it was a spelling mistake in the database name in connection string.

You say that if int(splitLine[0]) > int(lastUnix): is causing the trouble, but you don't actually show anything which suggests that. I think this line is the problem instead:

print 'Pulled', + stock

Do you see why this line could cause that error message? You want either

>>> stock = "AAAA"
>>> print 'Pulled', stock
Pulled AAAA

or

>>> print 'Pulled ' + stock
Pulled AAAA

not

>>> print 'Pulled', + stock
PulledTraceback (most recent call last):
  File "<ipython-input-5-7c26bb268609>", line 1, in <module>
    print 'Pulled', + stock
TypeError: bad operand type for unary +: 'str'

You're asking Python to apply the + symbol to a string like +23 makes a positive 23, and she's objecting.

After Ctrl+End, you can do the Ctrl+A to select all in the buffer and then paste into Excel. Excel even put each Oracle column into its own column instead of squishing the whole row into one column. Nice..

The git solution for such scenarios is setting SKIP-WORKTREE BIT. Run only the following command:

git update-index --skip-worktree .classpath .gitignore

It is used when you want git to ignore changes of files that are already managed by git and exist on the index. This is a common use case for config files.

Running git rm --cached doesn't work for the scenario mentioned in the question. If I simplify the question, it says:

How to have .classpath and .project on the repo while each one can change it locally and git ignores this change?

As I commented under the accepted answer, the drawback of git rm --cached is that it causes a change in the index, so you need to commit the change and then push it to the remote repository. As a result, .classpath and .project won't be available on the repo while the PO wants them to be there so anyone that clones the repo for the first time, they can use it.

What is SKIP-WORKTREE BIT?

Based on git documentaion:

Skip-worktree bit can be defined in one (long) sentence: When reading an entry, if it is marked as skip-worktree, then Git pretends its working directory version is up to date and read the index version instead. Although this bit looks similar to assume-unchanged bit, its goal is different from assume-unchanged bit’s. Skip-worktree also takes precedence over assume-unchanged bit when both are set.

More details is available here.

This works 1) for multiline text as well 2) and even in IE9!

<div class="measureText" id="measureText">
</div>


.measureText {
  margin: 0;
  padding: 0;
  border: 0;
  font-family: Arial;
  position: fixed;
  visibility: hidden;
  height: auto;
  width: auto;
  white-space: pre-wrap;
  line-height: 100%;
}

function getTextFieldMeasure(fontSize, value) {
    const div = document.getElementById("measureText");

    // returns wrong result for multiline text with last line empty
    let arr = value.split('\n');
    if (arr[arr.length-1].length == 0) {
        value += '.';
    }

    div.innerText = value;
    div.style['font-size']= fontSize + "px";
    let rect = div.getBoundingClientRect();

    return {width: rect.width, height: rect.height};
};

private static final int TAKE_PICTURE = 1;    
private Uri imageUri;

public void takePhoto(View view) {
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    File photo = new File(Environment.getExternalStorageDirectory(),  "Pic.jpg");
    intent.putExtra(MediaStore.EXTRA_OUTPUT,
            Uri.fromFile(photo));
    imageUri = Uri.fromFile(photo);
    startActivityForResult(intent, TAKE_PICTURE);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    switch (requestCode) {
    case TAKE_PICTURE:
        if (resultCode == Activity.RESULT_OK) {
            Uri selectedImage = imageUri;
            getContentResolver().notifyChange(selectedImage, null);
            ImageView imageView = (ImageView) findViewById(R.id.ImageView);
            ContentResolver cr = getContentResolver();
            Bitmap bitmap;
            try {
                 bitmap = android.provider.MediaStore.Images.Media
                 .getBitmap(cr, selectedImage);

                imageView.setImageBitmap(bitmap);
                Toast.makeText(this, selectedImage.toString(),
                        Toast.LENGTH_LONG).show();
            } catch (Exception e) {
                Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT)
                        .show();
                Log.e("Camera", e.toString());
            }
        }
    }
}

I had this problem as well and thought I'd share since I can't find my problem above.

This was my code

return RedirectToAction("Overview", model.Id);

Calling this ActionResult:

public ActionResult Overview(int id)

I assumed it would be smart enough to figure out that the value I pass it is the id paramter for Overview, but it's not. This fixed it:

return RedirectToAction("Overview", new {id = model.Id});

This might be an old question, but there's an alternate method you can use that no one has mentioned. It's possible to specify the password directly in the connection URI. The documentation can be found here, alternatively here.

You can provide your username and password directly in the connection URI provided to psql:

# postgresql://[user[:password]@][netloc][:port][/dbname][?param1=value1&...]
psql postgresql://username:password@localhost:5432/mydb

If array is type of objects, then the simplest way is

let foo_object // Item to remove
this.foo_objects = this.foo_objects.filter(obj => obj !== foo_object);

You can also specify a dependency not in a maven repository. Could be usefull when no central maven repository for your team exist or if you have a CI server

    <dependency>
        <groupId>com.stackoverflow</groupId>
        <artifactId>commons-utils</artifactId>
        <version>1.3</version>
        <scope>system</scope>
        <systemPath>${basedir}/lib/commons-utils.jar</systemPath>
    </dependency>

Just adding to the answers already given, the solution using the string "nunique" seems much faster, tested here on ~21M rows dataframe, then grouped to ~2M

%time _=g.agg({"id": lambda x: x.nunique()})
CPU times: user 3min 3s, sys: 2.94 s, total: 3min 6s
Wall time: 3min 20s

%time _=g.agg({"id": pd.Series.nunique})
CPU times: user 3min 2s, sys: 2.44 s, total: 3min 4s
Wall time: 3min 18s

%time _=g.agg({"id": "nunique"})
CPU times: user 14 s, sys: 4.76 s, total: 18.8 s
Wall time: 24.4 s

Found a very easy way to do this.

Open http://phpfiddle.org/

Paste following php script in box. In php script set API_ACCESS_KEY, set device ids separated by coma.

Press F9 or click Run.

For FCM, google url would be: https://fcm.googleapis.com/fcm/send

For FCM v1 google url would be: https://fcm.googleapis.com/v1/projects/YOUR_GOOGLE_CONSOLE_PROJECT_ID/messages:send

Note: While creating API Access Key on google developer console, you have to use 0.0.0.0/0 as ip address. (For testing purpose).

In case of receiving invalid Registration response from GCM server, please cross check the validity of your device token. You may check the validity of your device token using following url:

https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=YOUR_DEVICE_TOKEN

Some response codes:

Following is the description of some response codes you may receive from server.

{ "message_id": "XXXX" } - success
{ "message_id": "XXXX", "registration_id": "XXXX" } - success, device registration id has been changed mainly due to app re-install
{ "error": "Unavailable" } - Server not available, resend the message
{ "error": "InvalidRegistration" } - Invalid device registration Id 
{ "error": "NotRegistered"} - Application was uninstalled from the device

You can use ALTER command to modify the table schema.

The syntax for modifying the column size is

ALTER table table_name modify COLUMN column_name varchar (size);

A simple answer would be : No, it doesn't

Explanation : According to the definition of unique constraints (SQL-92)

A unique constraint is satisfied if and only if no two rows in a table have the same non-null values in the unique columns

This statement can have two interpretations as :

• No two rows can have same values i.e. NULL and NULL is not allowed
• No two non-null rows can have values i.e NULL and NULL is fine, but StackOverflow and StackOverflow is not allowed

Since MySQL follows second interpretation, multiple NULL values are allowed in UNIQUE constraint column. Second, if you would try to understand the concept of NULL in SQL, you will find that two NULL values can be compared at all since NULL in SQL refers to unavailable or unassigned value (you can't compare nothing with nothing). Now, if you are not allowing multiple NULL values in UNIQUE constraint column, you are contracting the meaning of NULL in SQL. I would summarise my answer by saying :

MySQL supports UNIQUE constraint but not on the cost of ignoring NULL values

You can use an enum in said parameters like this:

public enum Alignment { LEFT, RIGHT }
private static String drawCellValue(
int maxCellLength, String cellValue, Alignment align) {}

then you can use either a switch or if statement to actually do something with said parameter.

switch(align) {
case LEFT: //something
case RIGHT: //something
default: //something
}

if(align == Alignment.RIGHT) { /*code*/}

In case the issue surfaces when launching the application from within an IDE (i.e. starting from Eclipse or IntelliJ Idea), and using Maven, the key to the solution is in the Spring-boot Getting Started documentation:

If you are using Maven, execute:

mvn package && java -jar target/gs-spring-boot-0.1.0.jar

The important part of which is adding the package goal to be run before the application is actually started. (Idea: Run menu, Edit Configrations..., Add, and there select Run Maven Goal, and specify the package goal in the field)

Why is this not totally trivial? Doing the request is not and especially not dealing with the results and seems like there are some .NET bugs involved as well - see Bug in HttpClient.GetAsync should throw WebException, not TaskCanceledException

I ended up with this code:

static async Task<(bool Success, WebExceptionStatus WebExceptionStatus, HttpStatusCode? HttpStatusCode, string ResponseAsString)> HttpRequestAsync(HttpClient httpClient, string url, string postBuffer = null, CancellationTokenSource cts = null) {
    try {
        HttpResponseMessage resp = null;

        if (postBuffer is null) {
            resp = cts is null ? await httpClient.GetAsync(url) : await httpClient.GetAsync(url, cts.Token);

        } else {
            using (var httpContent = new StringContent(postBuffer)) {
                resp = cts is null ? await httpClient.PostAsync(url, httpContent) : await httpClient.PostAsync(url, httpContent, cts.Token);
            }
        }

        var respString = await resp.Content.ReadAsStringAsync();
        return (resp.IsSuccessStatusCode, WebExceptionStatus.Success, resp.StatusCode, respString);

    } catch (WebException ex) {
        WebExceptionStatus status = ex.Status;
        if (status == WebExceptionStatus.ProtocolError) {
            // Get HttpWebResponse so that you can check the HTTP status code.
            using (HttpWebResponse httpResponse = (HttpWebResponse)ex.Response) {
                return (false, status, httpResponse.StatusCode, httpResponse.StatusDescription);
            }
        } else {
            return (false, status, null, ex.ToString()); 
        }

    } catch (TaskCanceledException ex) {
        if (cts is object && ex.CancellationToken == cts.Token) {
            // a real cancellation, triggered by the caller
            return (false, WebExceptionStatus.RequestCanceled, null, ex.ToString());
        } else {
            // a web request timeout (possibly other things!?)
            return (false, WebExceptionStatus.Timeout, null, ex.ToString());
        }

    } catch (Exception ex) {
        return (false, WebExceptionStatus.UnknownError, null, ex.ToString());
    }
}

This will do a GET or POST depends if postBuffer is null or not

if Success is true the response will then be in ResponseAsString

if Success is false you can check WebExceptionStatus, HttpStatusCode and ResponseAsString to try to see what went wrong.

The cleanest way to do it is by using html5 selectors api, specifically querySelectorAll().

var contentToRemove = document.querySelectorAll("#myid");
$(contentToRemove).remove(); 

The querySelectorAll() function returns an array of dom elements matching a specific id. Once you have assigned the returned array to a var, then you can pass it as an argument to jquery remove().

The word "read" is vague, but here is an example which reads a jpeg file using the Image class, and prints information about it.

from PIL import Image
jpgfile = Image.open("picture.jpg")

print(jpgfile.bits, jpgfile.size, jpgfile.format)

The use of -X [WHATEVER] merely changes the request's method string used in the HTTP request. This is easier to understand with two examples — one with -X [WHATEVER] and one without — and the associated HTTP request headers for each:

# curl -XPANTS -o nul -v http://neverssl.com/
* Connected to neverssl.com (13.224.86.126) port 80 (#0)
> PANTS / HTTP/1.1
> Host: neverssl.com
> User-Agent: curl/7.42.0
> Accept: */*

# curl -o nul -v http://neverssl.com/
* Connected to neverssl.com (13.33.50.167) port 80 (#0)
> GET / HTTP/1.1
> Host: neverssl.com
> User-Agent: curl/7.42.0
> Accept: */*

My preferred method:

if (*ptr == 0) // empty string

Probably more common:

if (strlen(ptr) == 0) // empty string
