I think you have not installed these features. see below in picture.

I also suffered from this problem some days ago. After installing this feature then I solved it. If you have not installed this feature then installed it.

Install Process:

1. go to android studio
2. Tools
3. Android
4. SDK Manager
5. Appearance & Behavior
6. Android SDK

You could use componentDidMount and componentWillUnmount methods:

import React, { Component } from 'react';
import ReactDOM from 'react-dom';

class MovieItem extends Component
{
    _handleNVEvent = event => {
        ...
    };

    componentDidMount() {
        ReactDOM.findDOMNode(this).addEventListener('nv-event', this._handleNVEvent);
    }

    componentWillUnmount() {
        ReactDOM.findDOMNode(this).removeEventListener('nv-event', this._handleNVEvent);
    }

    [...]

}

export default MovieItem;

I may be simplifying the issue, but does td {border-right: 1px solid red;} work for your table setup?

import requests
url = "https://www.googleapis.com/qpxExpress/v1/trips/search?key=mykeyhere"
data = requests.get(url).json

maybe?

if you are trying to send a file

files = {'request_file': open('request.json', 'rb')}
r = requests.post(url, files=files)
print r.text, print r.json

ahh thanks @LukasGraf now i better understand what his original code is doing

import requests,json
url = "https://www.googleapis.com/qpxExpress/v1/trips/search?key=mykeyhere"
my_json_data = json.load(open("request.json"))
req = requests.post(url,data=my_json_data)
print req.text
print 
print req.json # maybe? 

You can simply run sudo service docker start which will start running your docker server. You can check if you have the docker server by running service --status-all, you should see docker listed.

USE:

 >>> a[[0,1,3]][:,[0,2]]
array([[ 0,  2],
   [ 4,  6],
   [12, 14]])

OR:

>>> a[[0,1,3],::2]
array([[ 0,  2],
   [ 4,  6],
   [12, 14]])

Try to set user.language and user.country properties in sqldeveloper.conf file located in sqldeveloper\bin folder (%APPDATA%\sqldeveloper\<version>\product.conf for more recent versions) .
Sample for set french language:

IncludeConfFile ../../ide/bin/ide.conf

SetJavaHome D:\jdk1.6.0_25

AddVMOption  -Doracle.ide.util.AddinPolicyUtils.OVERRIDE_FLAG=true

AddVMOption -Dsun.java2d.ddoffscreen=false

AddVMOption -Dwindows.shell.font.languages=
AddVMOption -Duser.language=fr
AddVMOption -Duser.country=FR
AddVMOption  -XX:MaxPermSize=128M

AddVMOption -Doracle.jdbc.mapDateToTimestamp=false  
IncludeConfFile  sqldeveloper-nondebug.conf

To switch off language try to remove its support by editing oracle.translated.locales option in ide.boot file (located in ide\bin folder).
For example, if I want to 'break' french language support this option will be:

oracle.translated.locales = de,es,it,ja,ko,pt_BR,zh_CN,zh_TW

The original value was:

oracle.translated.locales = de,fr,es,it,ja,ko,pt_BR,zh_CN,zh_TW

The configuration above (sqldeveloper.conf file) will be wrong after remove french support and the french language does not appear as GUI localization.

Can get using following sql statement:

select count(*) Noofcolumns from SYSCOLUMNS where id=(select id from SYSOBJECTS where name='table_name')

This also seems to do it. PS Example:

Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force

Here is query to find email's which are used for more then one login_id:

SELECT email
FROM table
GROUP BY email
HAVING count(*) > 1

You'll need second (of nested) query to get list of login_id by email.

Try this : (http://jsfiddle.net/TpqVx/)

.left-div {
    float: left;
    width: 100px;
    /*height: 20px;*/
    margin-right: 8px;
    background-color: linen;
}
.right-div {

    margin-left: 108px;
    background-color: lime;
}??

<div class="left-div">
    &nbsp;
</div>
<div class="right-div">
    My requirements are <b>[A]</b> Content in the two divs should line up at the top, <b>[B]</b> Long text in right-div should not wrap underneath left-div, and <b>[C]</b> I do not want to specify a width of right-div. I don't want to set the width of right-div because this markup needs to work within different widths.
</div>
<div style='clear:both;'>&nbsp;</div>

Hints :

• Just use float:left in your left-most div only.
• No real reason to use height, but anyway...
• Good practice to use <div 'clear:both'>&nbsp;</div> after your last div.

check all the variables names in both of the combined files. Name of variables of both files to be combines should be exact same or else it will produce the above mentioned errors. I was facing the same problem as well, and after making all names same in both the file, rbind works accurately.

Thanks

:goto 21490 will take you to the 21490th byte in the buffer.

Generating locales

Missing locales are generated with locale-gen:

locale-gen en_US.UTF-8

Alternatively a locale file can be created manually with localedef:[1]

localedef -i en_US -f UTF-8 en_US.UTF-8

Setting Locale Settings

The locale settings can be set (to en_US.UTF-8 in the example) as follows:

export LANGUAGE=en_US.UTF-8
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8
locale-gen en_US.UTF-8
dpkg-reconfigure locales

The dpkg-reconfigure locales command will open a dialog under Debian for selecting the desired locale. This dialog will not appear under Ubuntu. The Configure Locales in Ubuntu article shows how to find the information regarding Ubuntu.

In my case the problem was that https was unable to start correctly because Listen 443 was in "IfDefine SSL" derective, but my apache didnt start with -DSSL option. The fix was to change my apachectl script in:

$HTTPD -k $ARGV

to:

$HTTPD -k $ARGV -DSSL

Hope that helps somebody.

The path location must not contain á,à,â, and similars. Chinese characters or any other diferent than the usual alphabetical characters. For example, my path was C:\Users\Vinícius\AndroidStudioProjects\MyApplication .But my user name had the letter í. So I create a folder 'custom2222' and change the path to C:\custom2222\MyApplication

My solution

• Assuming that form id = "my_form_id"
• It detects the form method and form action from HTML

jQuery code

$('#my_form_id').on('submit', function(e) {
    e.preventDefault();
    var formData = new FormData($(this)[0]);
    var msg_error = 'An error has occured. Please try again later.';
    var msg_timeout = 'The server is not responding';
    var message = '';
    var form = $('#my_form_id');
    $.ajax({
        data: formData,
        async: false,
        cache: false,
        processData: false,
        contentType: false,
        url: form.attr('action'),
        type: form.attr('method'),
        error: function(xhr, status, error) {
            if (status==="timeout") {
                alert(msg_timeout);
            } else {
                alert(msg_error);
            }
        },
        success: function(response) {
            alert(response);
        },
        timeout: 7000
    });
});

Try:

apt-get install php5-sqlite

That worked for me.

I was receiving the same error message, and my issue was that I was not in the correct directory when running the command make install. When I changed to the directory that had my makefile it worked.

So possibly you aren't in the right directory.

Well, the problem you have is wrong line ending/encoding for notepad. Notepad uses Windows' line endings - \r\n and you use \n.

I had similar Issue where we have GenericResponse object containing list of values

 ResponseEntity<ResponseDTO> responseEntity = restTemplate.exchange(
                redisMatchedDriverUrl,
                HttpMethod.POST,
                requestEntity,
                ResponseDTO.class
        );

Usage of objectMapper helped in converting LinkedHashMap into respective DTO objects

 ObjectMapper mapper = new ObjectMapper();

 List<DriverLocationDTO> driverlocationsList = mapper.convertValue(responseDTO.getData(), new TypeReference<List<DriverLocationDTO>>() { });

Same thing just happened to me on Google Chrome v22.0.1221.1 (Nvidia GPU). The workaround was to disable GPU compositing on all pages (setting available on chrome://flags/)

If it happens in Chrome version > 45.x, See answer https://stackoverflow.com/a/32955808/293023 by @detale.

Use google-chrome -disable-gpu from the command line to temporary disable gpu.

To answer to your second question. You can just hit the IP address of the machine that your flask app is running, e.g. 192.168.1.100 in a browser on different machine on the same network and you are there. Though, you will not be able to access it if you are on a different network. Firewalls or VLans can cause you problems with reaching your application. If that computer has a public IP, then you can hit that IP from anywhere on the planet and you will be able to reach the app. Usually this might impose some configuration, since most of the public servers are behind some sort of router or firewall.

You have to define public String toString() method in your Student class. For example:

public String toString() {
  return "Student: " + studentName + ", " + studentNo;
}

pudb is a good drop-in replacement for pdb

Here is a time performance comparison between using np.where vs list_comprehension. Seems like np.where is faster on average.

# np.where
start_times = []
end_times = []
for i in range(10000):
    start = time.time()
    start_times.append(start)
    temp_list = np.array([1,2,3,3,5])
    ixs = np.where(temp_list==3)[0].tolist()
    end = time.time()
    end_times.append(end)
print("Took on average {} seconds".format(
    np.mean(end_times)-np.mean(start_times)))

Took on average 3.81469726562e-06 seconds

# list_comprehension
start_times = []
end_times = []
for i in range(10000):
    start = time.time()
    start_times.append(start)
    temp_list = np.array([1,2,3,3,5])
    ixs = [i for i in range(len(temp_list)) if temp_list[i]==3]
    end = time.time()
    end_times.append(end)
print("Took on average {} seconds".format(
    np.mean(end_times)-np.mean(start_times)))

Took on average 4.05311584473e-06 seconds

I know the question is old but I found this very helpful http://www.gnuplot.info/demo_canvas/dashcolor.html . So you can choose linetype and linecolor separately but you have to precede everything by "set termoption dash" (worked for me in gnuplot 4.4).

How about a workaround? In my case I took the value of the textarea in a jQuery variable, and changed all "<p>&nbsp" to <p class="clear"> and clear class to have certain height and margin, as the following example:

jQuery

tinyMCE.triggerSave();
var val = $('textarea').val();
val = val.replace(/<p>&nbsp/g, '<p class="clear">');

the val is then saved to the database with the new val.

CSS

p.clear{height: 2px; margin-bottom: 3px;}

You can adjust the height & margin as you wish. And since 'p' is a display: block element. it should give you the expected output.

Hope that helps!

Adding responseType to the request that is made from angular is indeed the solution, but for me it didn't work until I've set responseType to blob, not to arrayBuffer. The code is self explanatory:

    $http({
            method : 'GET',
            url : 'api/paperAttachments/download/' + id,
            responseType: "blob"
        }).then(function successCallback(response) {
            console.log(response);
             var blob = new Blob([response.data]);
             FileSaver.saveAs(blob, getFileNameFromHttpResponse(response));
        }, function errorCallback(response) {   
        });

In my case, I had copied some code from another project that was using Automapper - took me ages to work that one out. Just had to add automapper nuget package to project.

If an exception is thrown, finally runs. If an exception is not thrown, finally runs. If the exception is caught, finally runs. If the exception is not caught, finally runs.

Only time it does not run is when JVM exits.

Try to use this xPath expression:

//book/title[@lang='it']/..

That should give you all book nodes in "it" lang

use this hitCurl method for fetch all type of api response i.e. Get / Post

        function hitCurl($url,$param = [],$type = 'POST'){
        $ch = curl_init();
        if(strtoupper($type) == 'GET'){
            $param = http_build_query((array)$param);
            $url = "{$url}?{$param}";
        }else{
            curl_setopt_array($ch,[
                CURLOPT_POST => (strtoupper($type) == 'POST'),
                CURLOPT_POSTFIELDS => (array)$param,
            ]);
        }
        curl_setopt_array($ch,[
            CURLOPT_URL => $url,
            CURLOPT_RETURNTRANSFER => true,
        ]);
        $resp = curl_exec($ch);
        $statusCode = curl_getinfo($ch,CURLINFO_HTTP_CODE);
        curl_close($ch);
        return [
            'statusCode' => $statusCode,
            'resp' => $resp
        ];
    }

Demo function to test api

 function fetchApiData(){
        $url = 'https://postman-echo.com/get';
        $resp = $this->hitCurl($url,[
            'foo1'=>'bar1',
            'foo2'=>'bar2'
        ],'get');
        $apiData = "Getting header code {$resp['statusCode']}";
        if($resp['statusCode'] == 200){
            $apiData = json_decode($resp['resp']);
        }
        echo "<pre>";
        print_r ($apiData);
        echo "</pre>";
    }

I'm guessing you don't have a jquery form plugin included. ajaxSubmit isn't a core jquery function, I believe.

Something like this : http://jquery.malsup.com/form/

UPD

<script src="http://malsup.github.com/jquery.form.js"></script> 

For package developed in Visual Studio 2015, I found i must supply a value for the parameter (which would be the case when you deploy or run on different server) which sets the connection manager's connection string instead of using the design time value. This will suppress the error message. I think this could be a bug.

dtexec /project c:\mypath\ETL.ispac /package mypackage.dtsx /SET \Package.Variables[$Project::myParameterName];"myValueForTheParameter"

I tested this without or without parameterize the connection string, which is at the project level. The result was the same: i.e. I have to set the value for the parameter even thought it was not used.

int a=4; System.out.println(~a); Result would be :-5

'~' of any integer in java represents 1's complement of the no. for example i am taking ~4,which means in binary representation 0100. first , length of an integer is four bytes,i.e 4*8(8 bits for 1 byte)=32. So in system memory 4 is represented as 0000 0000 0000 0000 0000 0000 0000 0100 now ~ operator will perform 1's complement on the above binary no

i.e 1111 1111 1111 1111 1111 1111 1111 1011->1's complement the most significant bit represents sign of the no(either - or +) if it is 1 then sign is '-' if it is 0 then sign is '+' as per this our result is a negative number, in java the negative numbers are stored in 2's complement form, the acquired result we have to convert into 2's complement( first perform 1's complement and just add 1 to 1's complement). all the one will become zeros,except most significant bit 1(which is our sign representation of the number,that means for remaining 31 bits 1111 1111 1111 1111 1111 1111 1111 1011 (acquired result of ~ operator) 1000 0000 0000 0000 0000 0000 0000 0100 (1's complement)

1 (2's complement)

1000 0000 0000 0000 0000 0000 0000 0101 now the result is -5 check out this link for the video <[Bit wise operators in java] https://youtu.be/w4pJ4cGWe9Y

Simply do this:

<object data="resume.pdf" type="application/pdf" width="100%" height="800px"> 
  <p>It appears you don't have a PDF plugin for this browser.
   No biggie... you can <a href="resume.pdf">click here to
  download the PDF file.</a></p>  
</object>

I've found that a good solution to this type of question is:

:%!sed ...

(or perl if you prefer). IOW, rather than learning vim's regex peculiarities, use a tool you already know. Using perl would make the ? modifier work to ungreedy the match.

With a simple call of clear() it appears in the DOM that the corresponding input/textarea component still has its old value, so any following changes on that component (e.g. filling the component with a new value) will not be processed in time.

If you take a look in the selenium source code you'll find that the clear()-method is documented with the following comment:

/** If this element is a text entry element, this will clear the value. Has no effect on other elements. Text entry elements are INPUT and TEXTAREA elements. Note that the events fired by this event may not be as you'd expect. In particular, we don't fire any keyboard or mouse events. If you want to ensure keyboard events are fired, consider using something like {@link #sendKeys(CharSequence...)} with the backspace key. To ensure you get a change event, consider following with a call to {@link #sendKeys(CharSequence...)} with the tab key. */

So using this helpful hint to clear an input/textarea (component that already has a value) AND assign a new value to it, you'll get some code like the following:

public void waitAndClearFollowedByKeys(By by, CharSequence keys) {
    LOG.debug("clearing element");
    wait(by, true).clear();
    sendKeys(by, Keys.BACK_SPACE.toString() + keys);
}

public void sendKeys(By by, CharSequence keysToSend) {
    WebElement webElement = wait(by, true);
    LOG.info("sending keys '{}' to {}", escapeProperly(keysToSend), by);
    webElement.sendKeys(keysToSend);
    LOG.info("keys sent");
}

private String escapeProperly(CharSequence keysToSend) {
    String result = "" + keysToSend;
    result = result.replace(Keys.TAB, "\\t");
    result = result.replace(Keys.ENTER, "\\n");
    result = result.replace(Keys.RETURN, "\\r");

    return result;
}

Sorry for this code being Java and not Python. Also, I had to skip out an additional "waitUntilPageIsReady()-method that would make this post way too long.

Hope this helps you on your journey with Selenium!

Not sure at what version this capability arrived, but you can use something like this to return all the properties of multiple child registry entries in an array:

$InstalledSoftware = Get-ChildItem "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall" | ForEach-Object {Get-ItemProperty "Registry::$_"}

Only adding this as Google brought me here for a relevant reason and I eventually came up with the above one-liner for dredging the registry.

Given numpy, you could use linspace:

Including the right endpoint (5):

In [46]: import numpy as np
In [47]: np.linspace(0,5,10)
Out[47]: 
array([ 0.        ,  0.55555556,  1.11111111,  1.66666667,  2.22222222,
        2.77777778,  3.33333333,  3.88888889,  4.44444444,  5.        ])

Excluding the right endpoint:

In [48]: np.linspace(0,5,10,endpoint=False)
Out[48]: array([ 0. ,  0.5,  1. ,  1.5,  2. ,  2.5,  3. ,  3.5,  4. ,  4.5])

'' encloses single char, while "" encloses a String.

Change

y = 'hello';

-->

y = "hello";

Using Except is exactly the right way to go. If your type overrides Equals and GetHashCode, or you're only interested in reference type equality (i.e. two references are only "equal" if they refer to the exact same object), you can just use:

var list3 = list1.Except(list2).ToList();

If you need to express a custom idea of equality, e.g. by ID, you'll need to implement IEqualityComparer<T>. For example:

public class IdComparer : IEqualityComparer<CustomObject>
{
    public int GetHashCode(CustomObject co)
    {
        if (co == null)
        {
            return 0;
        }
        return co.Id.GetHashCode();
    }

    public bool Equals(CustomObject x1, CustomObject x2)
    {
        if (object.ReferenceEquals(x1, x2))
        {
            return true;
        }
        if (object.ReferenceEquals(x1, null) ||
            object.ReferenceEquals(x2, null))
        {
            return false;
        }
        return x1.Id == x2.Id;
    }
}

Then use:

var list3 = list1.Except(list2, new IdComparer()).ToList();

Note that this will remove any duplicate elements. If you need duplicates to be preserved, it would probably be easiest to create a set from list2 and use something like:

var list3 = list1.Where(x => !set2.Contains(x)).ToList();

Here's another solution that extends the "serializeArray" method (while preserving the original behavior).

//Store the reference to the original method:

var _serializeArray = $ji.fn.serializeArray;

//Now extend it with newer "unchecked checkbox" functionality:
$ji.fn.extend({
    serializeArray: function () {
        //Important: Get the results as you normally would...
        var results = _serializeArray.call(this);

        //Now, find all the checkboxes and append their "checked" state to the results.
        this.find('input[type=checkbox]').each(function (id, item) {
            var $item = $ji(item);
            var item_value = $item.is(":checked") ? 1 : 0;
            var item_name = $item.attr('name');
            var result_index = null;
            results.each(function (data, index) {
                if (data.name == item_name) {
                    result_index = index;
                }
            });

            if (result_index != null) {
                // FOUND replace previous value
                results[result_index].value = item_value;
            }
            else {
                // NO value has been found add new one
                results.push({name: item_name, value: item_value});
            }
        });
        return results;
    }
});

This will actually append "true" or "false" boolean results, but if you prefer you can use "1" and "0" respectively, by changing the value to value: $item.is(":checked") ? 1 : 0.

Usage

Just as usual, call the method on your form: $form.serialize() or $form.serializeArray(). What happens is that serialize makes use of serializeArray anyways, so you get the proper results (although different format) with whichever method you call.

Storing with json or serialized array is the best solution for now. With some situations (trimming " ' characters) json might be getting trouble but serialize should be great choice.

Note: If you change serialized data manually, you need to be careful about character count.

Well, the above does work, here is my solution that requires a little less markup and is more flexible.

.cells {_x000D_
  display: inline-block;_x000D_
  float: left;_x000D_
  padding: 1px;_x000D_
}_x000D_
.cells>.content {_x000D_
  background: #EEE;_x000D_
  display: table-cell;_x000D_
  float: left;_x000D_
  padding: 3px;_x000D_
  vertical-align: middle;_x000D_
}

<div id="div1" class="cells"><div class="content">My Cell 1</div></div>_x000D_
<div id="div2" class="cells"><div class="content">My Cell 2</div></div>

Polling like this is definitely the least preferred solution.

I assume that you have another thread that will do something to make the condition true. There are several ways to synchronize threads. The easiest one in your case would be a notification via an Object:

Main thread:

synchronized(syncObject) {
    try {
        // Calling wait() will block this thread until another thread
        // calls notify() on the object.
        syncObject.wait();
    } catch (InterruptedException e) {
        // Happens if someone interrupts your thread.
    }
}

Other thread:

// Do something
// If the condition is true, do the following:
synchronized(syncObject) {
    syncObject.notify();
}

syncObject itself can be a simple Object.

There are many other ways of inter-thread communication, but which one to use depends on what precisely you're doing.

Under Linux, to find the location of $JAVA_HOME:

readlink -f /usr/bin/java | sed "s:bin/java::"

the cacerts are under lib/security/cacerts:

$(readlink -f /usr/bin/java | sed "s:bin/java::")lib/security/cacerts

Under mac OS X , to find $JAVA_HOME run:

/usr/libexec/java_home

the cacerts are under Home/lib/security/cacerts:

$(/usr/libexec/java_home)/lib/security/cacerts

UPDATE (OS X with JDK)

above code was tested on computer without JDK installed. With JDK installed, as pR0Ps said, it's at

$(/usr/libexec/java_home)/jre/lib/security/cacerts

I used another solution using MarkupExtension.

1. I made class which provides items source:

   public class EnumToItemsSource : MarkupExtension
   {
       private readonly Type _type;
   
       public EnumToItemsSource(Type type)
       {
           _type = type;
       }
   
       public override object ProvideValue(IServiceProvider serviceProvider)
       {
           return Enum.GetValues(_type)
               .Cast<object>()
               .Select(e => new { Value = (int)e, DisplayName = e.ToString() });
       }
   }
   

2. That's almost all... Now use it in XAML:

       <ComboBox DisplayMemberPath="DisplayName"
             ItemsSource="{persons:EnumToItemsSource {x:Type enums:States}}"
             SelectedValue="{Binding Path=WhereEverYouWant}"
             SelectedValuePath="Value" />
   

3. Change 'enums:States' to your enum

you can also hide the gridline on yAxis as:

yAxis:{ 
  gridLineWidth: 0,
  minorGridLineWidth: 0
}

Functionally, they are equivalent.

Performance-wise map[key] = value would be quicker, as you are only making single lookup instead of two.

Style-wise, the shorter the better :)

The code will in most cases seem to work fine in multi-threaded context. It however is not thread-safe without extra synchronization.

Yes, you can run commands on the Ansible host. You can specify that all tasks in a play run on the Ansible host, or you can mark individual tasks to run on the Ansible host.

If you want to run an entire play on the Ansible host, then specify hosts: 127.0.0.1 and connection:local in the play, for example:

- name: a play that runs entirely on the ansible host
  hosts: 127.0.0.1
  connection: local
  tasks:
  - name: check out a git repository
    git: repo=git://foosball.example.org/path/to/repo.git dest=/local/path

See Local Playbooks in the Ansible documentation for more details.

If you just want to run a single task on your Ansible host, you can use local_action to specify that a task should be run locally. For example:

- name: an example playbook
  hosts: webservers
  tasks:
  - ...

  - name: check out a git repository
    local_action: git repo=git://foosball.example.org/path/to/repo.git dest=/local/path

See Delegation in the Ansible documentation for more details.

Edit: You can avoid having to type connection: local in your play by adding this to your inventory:

localhost ansible_connection=local

(Here you'd use "localhost" instead of "127.0.0.1" to refer to the play).

Edit: In newer versions of ansible, you no longer need to add the above line to your inventory, ansible assumes it's already there.

1. The class Date/Timestamp represents a specific instant in time, with millisecond precision, since January 1, 1970, 00:00:00 GMT. So this time difference (from epoch to current time) will be same in all computers across the world with irrespective of Timezone.

2. Date/Timestamp doesn't know about the given time is on which timezone.

3. If we want the time based on timezone we should go for the Calendar or SimpleDateFormat classes in java.

4. If you try to print a Date/Timestamp object using toString(), it will convert and print the time with the default timezone of your machine.

5. So we can say (Date/Timestamp).getTime() object will always have UTC (time in milliseconds)

6. To conclude Date.getTime() will give UTC time, but toString() is on locale specific timezone, not UTC.

Now how will I create/change time on specified timezone?

The below code gives you a date (time in milliseconds) with specified timezones. The only problem here is you have to give date in string format.

   DateFormat dateFormat = new SimpleDateFormat("yyyyMMdd HH:mm:ss");
   dateFormatLocal.setTimeZone(timeZone);
   java.util.Date parsedDate = dateFormatLocal.parse(date);

Use dateFormat.format for taking input Date (which is always UTC), timezone and return date as String.

How to store UTC/GMT time in DB:

If you print the parsedDate object, the time will be in default timezone. But you can store the UTC time in DB like below.

        Calendar calGMT = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
        Timestamp tsSchedStartTime = new Timestamp (parsedDate.getTime());
        if (tsSchedStartTime != null) {
            stmt.setTimestamp(11, tsSchedStartTime, calGMT );
        } else {
            stmt.setNull(11, java.sql.Types.DATE);
        }

If, while using the mysql_upgrade -u root -p --force command You get this error:

Could not create the upgrade info file '/var/lib/mysql/mysql_upgrade_info' in the MySQL Servers datadir, errno: 13

just add the sudo before the command. That worked for me, and I solved my problem. So, it's: sudo mysql_upgrade -u root -p --force :)

You can use "lsof" to find open logfiles on your system. lsof just gives you a list of all open files.

Use grep for "log" ... use grep again for "php" (if the filename contains the strings "log" and "php" like in "php_error_log" and you are root user you will find the files without knowing the configuration).

        root@lnx-work:~# lsof |grep log
        ... snip
        gmain     12148 12274       user   13r      REG              252,1    32768     661814 /home/user/.local/share/gvfs-metadata/home-11ab0393.log

Use for...in loop:

for (var key in obj) {
   console.log(' name=' + key + ' value=' + obj[key]);

   // do some more stuff with obj[key]
}

An abstract class can be used instead of an interface (in C# 7.3).

// Like interface
abstract class IIO
{
    public virtual async Task<string> DoOperation(string Name)
    {
        throw new NotImplementedException(); // throwing exception
        // return await Task.Run(() => { return ""; }); // or empty do
    }
}

// Implementation
class IOImplementation : IIO
{
    public override async Task<string> DoOperation(string Name)
    {
        return await await Task.Run(() =>
        {
            if(Name == "Spiderman")
                return "ok";
            return "cancel";
        }); 
    }
}

Try this simple solution to convert file to base64 string

String base64String = imageFileToByte(file);

public String imageFileToByte(File file){

    Bitmap bm = BitmapFactory.decodeFile(file.getAbsolutePath());
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    bm.compress(Bitmap.CompressFormat.JPEG, 100, baos); //bm is the bitmap object
    byte[] b = baos.toByteArray();
    return Base64.encodeToString(b, Base64.DEFAULT);
}

My setup was a little different using XAMPP. in httpd-xampp.conf I had to make the following change.

Alias /phpmyadmin "C:/xampp/phpMyAdmin/"
<Directory "C:/xampp/phpMyAdmin">
    AllowOverride AuthConfig
    Require local
    ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</Directory>

change to

Alias /phpmyadmin "C:/xampp/phpMyAdmin/"
<Directory "C:/xampp/phpMyAdmin">
    AllowOverride AuthConfig
    #makes it so I can config the database from anywhere
    #change the line below
    Require all granted
    ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</Directory>

I need to state that I'm brand new at this so I'm just hacking around but this is how I got it working.

import sys

try:
  print("stuff")
except:
  sys.exit(1) # exiing with a non zero value is better for returning from an error

None of the above answers worked "out of the box" for me, however, the following function, obtained by copying the ideas of the other answers works:

apply_func_2_cols = @(f,M) cell2mat(cellfun(f,num2cell(M,1), 'UniformOutput',0));

It takes a function f and applies it to every column of the matrix M.

So for example:

f = @(v) [0 1;1 0]*v + [0 0.1]';
apply_func_2_cols(f,[0 0 1 1;0 1 0 1])

 ans =

   0.00000   1.00000   0.00000   1.00000
   0.10000   0.10000   1.10000   1.10000

There are two ways of getting query params:

1. Using reqeust.URL.Query()
2. Using request.Form

In second case one has to be careful as body parameters will take precedence over query parameters. A full description about getting query params can be found here

https://golangbyexample.com/net-http-package-get-query-params-golang

The state of the checkbox will be reflected on whatever model you have it bound to, in this case, $scope.answers[item.questID]

Subscript out of Range error occurs when you try to reference an Index for a collection that is invalid.

Most likely, the index in Windows does not actually include .xls. The index for the window should be the same as the name of the workbook displayed in the title bar of Excel.

As a guess, I would try using this:

Windows("Data Sheet - " & ComboBox_Month.Value & " " & TextBox_Year.Value).Activate

It works for me after removing -XX:+UseParallelOldGC option from file.

The reason for this error is that in Python 3, strings are Unicode, but when transmitting on the network, the data needs to be bytes instead. So... a couple of suggestions:

1. Suggest using c.sendall() instead of c.send() to prevent possible issues where you may not have sent the entire msg with one call (see docs).
2. For literals, add a 'b' for bytes string: c.sendall(b'Thank you for connecting')
3. For variables, you need to encode Unicode strings to byte strings (see below)

Best solution (should work w/both 2.x & 3.x):

output = 'Thank you for connecting'
c.sendall(output.encode('utf-8'))

Epilogue/background: this isn't an issue in Python 2 because strings are bytes strings already -- your OP code would work perfectly in that environment. Unicode strings were added to Python in releases 1.6 & 2.0 but took a back seat until 3.0 when they became the default string type. Also see this similar question as well as this one.

You can't decrypt password in mysql, because password is hashed by using md5 hash algorithm, which is not an encoding algorithm.

Objective C Solution

NSArray * array = @[@"1", @"2", @"3"];
NSString * stringFromArray = [[array valueForKey:@"description"] componentsJoinedByString:@"-"];   // "1-2-3"

Those who are looking for a solution in Swift

If the array contains strings, you can use the String's join method:

var array = ["1", "2", "3"]

let stringFromArray = "-".join(array) // "1-2-3"

In Swift 2:

var array = ["1", "2", "3"]

let stringFromArray = array.joinWithSeparator("-") // "1-2-3"

In Swift 3 & 4

var array = ["1", "2", "3"]

let stringFromArray = array.joined(separator: "-") // "1-2-3"

Technically, it's 'possible', but under very strict conditions (rainbow tables, brute forcing based on the very small possibility that a user's password is in that hash database).

But that doesn't mean it's

• Viable
  or
• Secure

You don't want to 'reverse' an MD5 hash. Using the methods outlined below, you'll never need to. 'Reversing' MD5 is actually considered malicious - a few websites offer the ability to 'crack' and bruteforce MD5 hashes - but all they are are massive databases containing dictionary words, previously submitted passwords and other words. There is a very small chance that it will have the MD5 hash you need reversed. And if you've salted the MD5 hash - this won't work either! :)

The way logins with MD5 hashing should work is:

During Registration:
User creates password -> Password is hashed using MD5 -> Hash stored in database

During Login:
User enters username and password -> (Username checked) Password is hashed using MD5 -> Hash is compared with stored hash in database

When 'Lost Password' is needed:

2 options:

• User sent a random password to log in, then is bugged to change it on first login.
  

or

• User is sent a link to change their password (with extra checking if you have a security question/etc) and then the new password is hashed and replaced with old password in database

An alternative way is to install the Maven for Java plugin and create a maven project within Visual Studio. The steps are described in the official documentation:

1. From the Command Palette (Crtl+Shift+P), select Maven: Generate from Maven Archetype and follow the instructions, or
2. Right-click on a folder and select Generate from Maven Archetype.

Just multiply the number by 100, round, and divide the resulting number by 100.

Update: It finally made it into JavaScript (ECMAScript 2018)!

Named capturing groups could make it into JavaScript very soon.
The proposal for it is at stage 3 already.

A capture group can be given a name inside angular brackets using the (?<name>...) syntax, for any identifier name. The regular expression for a date then can be written as /(?<year>\d{4})-(?<month>\d{2})-(?<day>\d{2})/u. Each name should be unique and follow the grammar for ECMAScript IdentifierName.

Named groups can be accessed from properties of a groups property of the regular expression result. Numbered references to the groups are also created, just as for non-named groups. For example:

let re = /(?<year>\d{4})-(?<month>\d{2})-(?<day>\d{2})/u;
let result = re.exec('2015-01-02');
// result.groups.year === '2015';
// result.groups.month === '01';
// result.groups.day === '02';

// result[0] === '2015-01-02';
// result[1] === '2015';
// result[2] === '01';
// result[3] === '02';

I had a similar situation with this issue. In this case it would have looked like this

Sub Test()
   MsqBox ("Hello world")
End Sub

The problem was, that I had a lot more code there and couldn't recognize, that there was a misspelling in "MsqBox" (q instead of g) and therefore I had an error, it was really misleading, but since you can get on this error like that, maybe someone else will notice that it was cause by a misspelling like this...

Try using "/" instead of "\" for the path to your image. Some comments here seem to come from people that do not understand some of us are simply learning web development which in many cases is best done locally. So instead of using src=C:\Pics\H.gif use src="C:/Pics/H.gif" for an absolute path or just src="Pics/H.gif" for a relative path if your Pics are in a sub-directory of your html page's location). Note also, it is good practice to surround your path with quotes. otherwise you will have problems with paths that include spaces and other odd characters.

The Host property will return the domain name you used when accessing the site. So, in your development environment, since you're requesting

http://localhost:950/m/pages/Searchresults.aspx?search=knife&filter=kitchen

It's returning localhost. You can break apart your URL like so:

Protocol: http
Host: localhost
Port: 950
PathAndQuery: /m/pages/SearchResults.aspx?search=knight&filter=kitchen

I think this is just what you'er looking for:

ls | xargs -I {} mv {} Unix_{}

Yes, it is simple yet elegant and powerful, and also one-liner. You can get more detailed intro from me on the page:Rename Files and Directories (Add Prefix)

As a counter point to the general thrust of the other answers. See The Many Benefits of Money…Data Type! in SQLCAT's Guide to Relational Engine

Specifically I would point out the following

Working on customer implementations, we found some interesting performance numbers concerning the money data type. For example, when Analysis Services was set to the currency data type (from double) to match the SQL Server money data type, there was a 13% improvement in processing speed (rows/sec). To get faster performance within SQL Server Integration Services (SSIS) to load 1.18 TB in under thirty minutes, as noted in SSIS 2008 - world record ETL performance, it was observed that changing the four decimal(9,2) columns with a size of 5 bytes in the TPC-H LINEITEM table to money (8 bytes) improved bulk inserting speed by 20% ... The reason for the performance improvement is because of SQL Server’s Tabular Data Stream (TDS) protocol, which has the key design principle to transfer data in compact binary form and as close as possible to the internal storage format of SQL Server. Empirically, this was observed during the SSIS 2008 - world record ETL performance test using Kernrate; the protocol dropped significantly when the data type was switched to money from decimal. This makes the transfer of data as efficient as possible. A complex data type needs additional parsing and CPU cycles to handle than a fixed-width type.

So the answer to the question is "it depends". You need to be more careful with certain arithmetical operations to preserve precision but you may find that performance considerations make this worthwhile.

I was having the issue previously in XAMPP localhost with phpmyadmin version 4.2.11.

Increasing the timeout in php.ini didn't helped either.

Then I edited xampp\phpMyAdmin\libraries\config.default.php to change the value of $cfg['ExecTimeLimit'], which was 300 by default.

That solved my issue.

You can't do a bulk-update in SSIS within a dataflow task with the OOB components.

The general pattern is to identify your inserts, updates and deletes and push the updates and deletes to a staging table(s) and after the Dataflow Task, use a set-based update or delete in an Execute SQL Task. Look at Andy Leonard's Stairway to Integration Services series. Scroll about 3/4 the way down the article to "Set-Based Updates" to see the pattern.

Stage data

Set based updates

You'll get much better performance with a pattern like this versus using the OLE DB Command transformation for anything but trivial amounts of data.

If you are into third party tools, I believe CozyRoc and I know PragmaticWorks have a merge destination component.

my solution:

background-image: url(IMAGE_URL); /* fallback */

background-image: linear-gradient(to bottom, rgba(0,0,0,0.7) 0%,rgba(0,0,0,0.7) 100%), url(IMAGE_URL);

in Kotlin I wrote these extensions:

fun MenuItem.setTitleColor(color: Int) {
    val hexColor = Integer.toHexString(color).toUpperCase().substring(2)
    val html = "<font color='#$hexColor'>$title</font>"
    this.title = html.parseAsHtml()
}           



@Suppress("DEPRECATION")                                                                        
fun String.parseAsHtml(): Spanned {                                                             
    return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {                                
        Html.fromHtml(this, Html.FROM_HTML_MODE_LEGACY)                                         
    } else {                                                                                    
        Html.fromHtml(this)                                                                     
    }                                                                                           
}  

and used like this:

menu.findItem(R.id.main_settings).setTitleColor(Color.RED)

I believe tuple() takes a list as an argument For example,

tuple([1,2,3]) # returns (1,2,3)

see what happens if you wrap your array with brackets

Alternatively to calling plt.show() at the end of the script, you can also control each figure separately doing:

f = plt.figure(1)
plt.hist........
............
f.show()

g = plt.figure(2)
plt.hist(........
................
g.show()

raw_input()

In this case you must call raw_input to keep the figures alive. This way you can select dynamically which figures you want to show

Note: raw_input() was renamed to input() in Python 3

You could try the problems at RosettaCode, many of which lack Java solutions at the moment. The problems are of many different difficulties, but each has a solution already in another language which should help with the algorithmic side.

There are errors in your meta tag.

Yours:

<meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src: 'self' 'unsafe-inline' 'unsafe-eval'>

Corrected:

<meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' 'unsafe-eval'"/>

Note the colon after "script-src", and the end double-quote of the meta tag.

You can add extra data with form data

use serializeArray and add the additional data:

var data = $('#myForm').serializeArray();
    data.push({name: 'tienn2t', value: 'love'});
    $.ajax({
      type: "POST",
      url: "your url.php",
      data: data,
      dataType: "json",
      success: function(data) {
          //var obj = jQuery.parseJSON(data); if the dataType is not     specified as json uncomment this
        // do what ever you want with the server response
     },
    error: function() {
        alert('error handing here');
    }
});

You need to concatenate your string.

document.getElementById(tabName).style.backgroundImage = 'url(buttons/' + imagePrefix + '.png)';

The way you had it, it's just making 1 long string and not actually interpreting imagePrefix.

I would even suggest creating the string separate:

function ChangeBackgroungImageOfTab(tabName, imagePrefix)
{
    var urlString = 'url(buttons/' + imagePrefix + '.png)';
    document.getElementById(tabName).style.backgroundImage =  urlString;
}

As mentioned by David Thomas below, you can ditch the double quotes in your string. Here is a little article to get a better idea of how strings and quotes/double quotes are related: http://www.quirksmode.org/js/strings.html

UPDATE

In Android Studio Version 3.5 and Above

Now Instant Run is removed, It has "Apply Changes". See official blog for more about the change.

we removed Instant Run and re-architectured and implemented from the ground-up a more practical approach in Android Studio 3.5 called Apply Changes.Apply Changes uses platform-specific APIs from Android Oreo and higher to ensure reliable and consistent behavior; unlike Instant Run, Apply Changes does not modify your APK. To support the changes, we re-architected the entire deployment pipeline to improve deployment speed, and also tweaked the run and deployment toolbar buttons for a more streamlined experience.

Now, As per stable available version 3.0 of Android studio,

If you need to turn off Instant Run, go to

File ? Settings ? Build, Execution, Deployment ? Instant Run and uncheck Enable Instant Run.

You have to make one ajax call to get the required result, in this case you can use Google API to get the same

http://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&sensor=true/false

Build this kind of url and replace the lat long with the one you want to. do the call and response will be in JSON, parse the JSON and you will get the complete address up to street level

You have to use the SelectMany extension method or its equivalent syntax in pure LINQ.

(from model in list
 where model.application == "applicationname"
 from user in model.users
 where user.surname == "surname"
 select new { user, model }).ToList();

In most circumstances, I recommend using the <object> tag to display SVG images. It feels a little unnatural, but it's the most reliable method if you want to provide dynamic effects.

For images without interaction, the <img> tag or a CSS background can be used.

Inline SVGs or iframes are possible options for some projects, but it's best to avoid <embed>

But if you want to play with SVG stuff like

• Changing colors
• Resize path
• rotate svg

Go with the embedded one

<svg>
    <g> 
        <path> </path>
    </g>
</svg>

int[] toIntArray(List<Integer> list)  {
    int[] ret = new int[list.size()];
    int i = 0;
    for (Integer e : list)  
        ret[i++] = e;
    return ret;
}

Slight change to your code to avoid expensive list indexing (since a List is not necessarily an ArrayList, but could be a linked list, for which random access is expensive)

Instance variable is the variable declared inside a class, but outside a method: something like:

class IronMan {

    /** These are all instance variables **/
    public String realName;
    public String[] superPowers;
    public int age;

    /** Getters and setters here **/
}

Now this IronMan Class can be instantiated in another class to use these variables. Something like:

class Avengers {

    public static void main(String[] a) {
        IronMan ironman = new IronMan();
        ironman.realName = "Tony Stark";
        // or
        ironman.setAge(30);
    }

}

This is how we use the instance variables. Shameless plug: This example was pulled from this free e-book here here.

I've came across this 'problem' as well but found a rather logical solution by adding the name attribute. I couldn't recall having this problem in other languages.

http://www.w3.org/TR/html401/interact/forms.html#h-17.13.2

• ...
• If a form contains more than one submit button, only the activated submit button is successful.
• ...

Meaning the following code value attributes can be changed, localized, internationalized without the need for extra code checking strongly-typed resources files or constants.

<% Html.BeginForm("MyAction", "MyController", FormMethod.Post); %>
<input type="submit" name="send" value="Send" />
<input type="submit" name="cancel" value="Cancel" />
<input type="submit" name="draft" value="Save as draft" />
<% Html.EndForm(); %>`

On the receiving end you would only need to check if any of your known submit types isn't null

public ActionResult YourAction(YourModel model) {

    if(Request["send"] != null) {

        // we got a send

    }else if(Request["cancel"]) {

        // we got a cancel, but would you really want to post data for this?

    }else if(Request["draft"]) {

        // we got a draft

    }

}

I'm using the rake approach (as supported by heroku)

With a file called lib/tasks/cron.rake ..

task :cron => :environment do
  puts "Pulling new requests..."
  EdiListener.process_new_messages
  puts "done."
end

To execute from the command line, this is just "rake cron". This command can then be put on the operating system cron/task scheduler as desired.

Update this is quite an old question and answer! Some new info:

• the heroku cron service I referenced has since been replaced by Heroku Scheduler
• for frequent tasks (esp. where you want to avoid the Rails environment startup cost) my preferred approach is to use system cron to call a script that will either (a) poke a secure/private webhook API to invoke the required task in the background or (b) directly enqueue a task on your queuing system of choice

If you are using Android then you can use android.util.Base64 class.

Encode:

passwd = Base64.encodeToString( passwd.getBytes(), Base64.DEFAULT );

Decode:

passwd = new String( Base64.decode( passwd, Base64.DEFAULT ) );

A simple and fast single line solution.

If you get an exception for : Invalid column type

Please use getNamedParameterJdbcTemplate() instead of getJdbcTemplate()

 List<Foo> foo = getNamedParameterJdbcTemplate().query("SELECT * FROM foo WHERE a IN (:ids)",parameters,
 getRowMapper());

Note that the second two arguments are swapped around.

a = 0.000006;
b = 6;
c = a/b;

textbox.Text = c.ToString("0.000000");

As you requested:

textbox.Text = c.ToString("0.######");

This will only display out to the 6th decimal place if there are 6 decimals to display.

Only solution that worked for me

$ sudo killall -u username && sudo deluser --remove-home -f username

The killall command is used if multiple processes are used by the user you want to delete.

The -f option forces the removal of the user account, even if the user is still logged in. It also forces deluser to remove the user's home directory and mail spool, even if another user uses the same home directory.

Please confirm that it works in the comments.

You only need to use "copy":

On that's way you iterate over the original dictionary fields and on the fly can change the desired dict (d dict). It's work on each python version, so it's more clear.

In [1]: d = {'a': [1], 'b': [1, 2], 'c': [], 'd':[]}

In [2]: for i in d.copy():
   ...:     if not d[i]:
   ...:         d.pop(i)
   ...:         

In [3]: d
Out[3]: {'a': [1], 'b': [1, 2]}

I have used command hcicongif with two greps to separate the PC Mac address and I saved the MAC address to variable:

PCMAC=$( hciconfig -a | grep -E 'BD Address:' | grep -Eo '[A-F0-9]{2}:[A-F0-9]{2}:[A-F0-9]{2}:[A-F0-9]{2}:[A-F0-9]{2}:[A-F0-9]{2}' )

You can also use this command to check if MAC address is in valid format. Note, that only big chars A-F are allowed and also you need to add input for this grep command:

grep -E '[A-F0-9]{2}:[A-F0-9]{2}:[A-F0-9]{2}:[A-F0-9]{2}:[A-F0-9]{2}:[A-F0-9]{2}'

Since the switch statement expresses the same intent as your if / else chain but in a more restricted, formal manner, your first guess should be that the compiler will be able to optimize it better, since it can draw more conclusions about the conditions placed on your code (i.e. only one state can possibly be true, the value being compared is a primitive type, etc.) This is a pretty safe general truth when you are comparing two similar language structures for runtime performance.

In Android Studio, which, quite honestly, you should be using, change the package name by right-clicking on the package name in the project structure -> Refactor -> Rename...

It then gives the option of renaming the directory or the package. Select the package. The directory should follow suit. Type in your new package name, and click Refactor. It will change all the imports and remove redundant imports for you. You can even have it fix it for you in comments and strings, etc.

Lastly, change the package name accordingly in your AndroidManifest.xml towards the top. Otherwise you will get errors everywhere complaining about R.whatever.

Another very useful solution

First create a new package with the desired nameby right clicking on thejava folder -> new -> package.`

Then, select and drag all your classes to the new package. AndroidStudio will re-factor the package name everywhere.

After that: in your app's build.gradle add/edit applicationId with the new one. i.e. (com.a.bc in my case):

defaultConfig {
    applicationId "com.a.bc"
    minSdkVersion 13
    targetSdkVersion 19
}

Original post and more comments here

You'll need some sort of uniquely identifying column in your table, like an auto-filling primary key or a datetime column (preferably the primary key). Then you can do this:

SELECT * FROM table_name ORDER BY unique_column DESC LIMIT 1

The ORDER BY column tells it to rearange the results according to that column's data, and the DESC tells it to reverse the results (thus putting the last one first). After that, the LIMIT 1 tells it to only pass back one row.

The XRegExp library has a plugin named Unicode that helps solve tasks like this.

<script src="xregexp.js"></script>
<script src="addons/unicode/unicode-base.js"></script>
<script>
  var unicodeWord = XRegExp("^\\p{L}+$");

  unicodeWord.test("???????"); // true
  unicodeWord.test("???"); // true
  unicodeWord.test("???????"); // true
</script>

It's mentioned in the comments to the question, but it's easy to miss. I've noticed it only after I submitted this answer.

It works and you don't need to implement EnvironmentAware. But I don't know drawbacks of this approach.

You're running into a CORS error.

Trying to access your file using the local file system doesn't work in your case.

Origin is null because it's your local file system. Could you possibly host this png file?

Suggestion:

Host these files to an AWS S3 bucket instead. Then you can use the http protocol rather than the file protocol. OR setup some http server on your local system and use http to your localhost to serve the files from if you want to keep everything local.

How CORS Works

For example,

package main

import "fmt"

func main() {
    type Map1 map[string]interface{}
    type Map2 map[string]int
    m := Map1{"foo": Map2{"first": 1}, "boo": Map2{"second": 2}}
    //m = map[foo:map[first: 1] boo: map[second: 2]]
    fmt.Println("m:", m)
    for k, v := range m {
        fmt.Println("k:", k, "v:", v)
    }
}

Output:

m: map[boo:map[second:2] foo:map[first:1]]
k: boo v: map[second:2]
k: foo v: map[first:1]

You can do something like this.

Select distinct name from  (SELECT r.name FROM outsider_role_mapping orm1 
    union all
SELECT r.name FROM user_role_mapping orm2
) tmp;

This should do it:

HTML

<input name="Name" value="Enter Your Name" onClick="blankDefault('Enter Your Name', this)">

JavaScript

function blankDefault(_text, _this) {
    if(_text == _this.value)
        _this.value = '';
}

There are better/less obtrusive ways though, but this will get the job done.

If you're brand new to using unittests, the simplest approach to learn is often the best. On that basis along I recommend using py.test rather than the default unittest module.

Consider these two examples, which do the same thing:

Example 1 (unittest):

import unittest

class LearningCase(unittest.TestCase):
    def test_starting_out(self):
        self.assertEqual(1, 1)

def main():
    unittest.main()

if __name__ == "__main__":
    main()

Example 2 (pytest):

def test_starting_out():
    assert 1 == 1

Assuming that both files are named test_unittesting.py, how do we run the tests?

Example 1 (unittest):

cd /path/to/dir/
python test_unittesting.py

Example 2 (pytest):

cd /path/to/dir/
py.test

Just making code shorter you can use ES6 features. The same things can be written as

app.get("/recipes", (req, res) => {
    res.render("recipes.ejs", {
        recipes
    });
}); 

And the Templeate can be render as the same!

<%if (recipes.length > 0) { %>
// Do something with more than 1 recipe
<% } %>

Date date = new Date();
Calendar cal = Calendar.getInstance();
cal.setTime(date);
cal.set(Calendar.HOUR_OF_DAY, 0);
cal.set(Calendar.MINUTE, 0);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);
date = cal.getTime();

Test:

There is one example where in actually kills your performance.

If you use in on a O(1) container that only implements __getitem__ and has_key() but not __contains__ you will turn an O(1) search into an O(N) search (as in falls back to a linear search via __getitem__).

Fix is obviously trivial:

def __contains__(self, x):
    return self.has_key(x)

More flexibility using .query with Pandas >= 0.25.0:

August 2019 updated answer

Since Pandas >= 0.25.0 we can use the query method to filter dataframes with Pandas methods and even column names which have spaces. Normally the spaces in column names would give an error, but now we can solve that using a backtick (`) - see GitHub:

# Example dataframe
df = pd.DataFrame({'Sender email':['[email protected]', "[email protected]", "[email protected]"]})

     Sender email
0  [email protected]
1  [email protected]
2    [email protected]

Using .query with method str.endswith:

df.query('`Sender email`.str.endswith("@shop.com")')

Output

     Sender email
1  [email protected]
2    [email protected]

Also we can use local variables by prefixing it with an @ in our query:

domain = 'shop.com'
df.query('`Sender email`.str.endswith(@domain)')

Output

     Sender email
1  [email protected]
2    [email protected]

Today i faced same issue, unfortunately, i was having two aliases in my keystore file.

Its already answered above. I will summarise the steps to check above.

run git remote -v in project dir. If the output shows remote url starting with https://abc then you may need username password everytime.

So to change the remote url run git remote set-url origin {ssh remote url address starts with mostly [email protected]:}.

Now run git remote -v to verify the changed remote url.

Refer : https://help.github.com/articles/changing-a-remote-s-url/

Match any single character

• Use the dot . character as a wildcard to match any single character.

Example regex: a.c

abc   // match
a c   // match
azc   // match
ac    // no match
abbc  // no match

Match any specific character in a set

• Use square brackets [] to match any characters in a set.
• Use \w to match any single alphanumeric character: 0-9, a-z, A-Z, and _ (underscore).
• Use \d to match any single digit.
• Use \s to match any single whitespace character.

Example 1 regex: a[bcd]c

abc   // match
acc   // match
adc   // match
ac    // no match
abbc  // no match

Example 2 regex: a[0-7]c

a0c   // match
a3c   // match
a7c   // match
a8c   // no match
ac    // no match
a55c  // no match

Match any character except ...

Use the hat in square brackets [^] to match any single character except for any of the characters that come after the hat ^.

Example regex: a[^abc]c

aac   // no match
abc   // no match
acc   // no match
a c   // match
azc   // match
ac    // no match
azzc  // no match

(Don't confuse the ^ here in [^] with its other usage as the start of line character: ^ = line start, $ = line end.)

Match any character optionally

Use the optional character ? after any character to specify zero or one occurrence of that character. Thus, you would use .? to match any single character optionally.

Example regex: a.?c

abc   // match
a c   // match
azc   // match
ac    // match
abbc  // no match

Yes, many changes at Heroku. If you're using a Heroku dyno for your webserver, you have to find way to alias from one DNS name to another DNS name (since each Heroku DNS endpoint may resolve to many IP addrs to dynamically adjust to request loads).

A CNAME record is for aliasing www.example.com -> www.example.com.herokudns.com.

You can't use CNAME for a naked domain (@), i.e. example.com (unless you find a name server that can do CNAME Flattening - which is what I did).

But really the easiest solution, that can pretty much be taken care of all in your GoDaddy account, is to create a CNAME record that does this: www.example.com -> www.example.com.herokudns.com.

And then create a permanent 301 redirect from example.com to www.example.com.

This requires only one heroku custom domain name configured in your heroku app settings: www.example.com.herokudns.com. @Jonathan Roy talks about this (above) but provides a bad link.

I think I found what you are looking for since I was also looking for it.

You have to follow Pawel's steps and then go to the key that is "Cookie". This will open a submenu with all the cookies and it specifies their name, value, domain, etc...

Respectively the values are: Key, Value, Expiration Date, Domain, Path.

This shows all the keys for this domain.

So again to get there:

1. Go to Network.
2. Capture Traffic, green triangle.
3. Go to Details.
4. Go to the "Cookie" key that has a gibberish value. (_utmc=xxxxx;something=ajksdhfa) etc...

You will have to annotate your service with @Service since you have said I am using annotations for mapping

string t = DateTime.Now.ToString("h/m/s tt");
string t2 = DateTime.Now.ToString("hh:mm:ss tt");
string d = DateTime.Now.ToString("MM/dd/yy");

A Data Transfer Object is an object that is used to encapsulate data, and send it from one subsystem of an application to another.

DTOs are most commonly used by the Services layer in an N-Tier application to transfer data between itself and the UI layer. The main benefit here is that it reduces the amount of data that needs to be sent across the wire in distributed applications. They also make great models in the MVC pattern.

Another use for DTOs can be to encapsulate parameters for method calls. This can be useful if a method takes more than 4 or 5 parameters.

When using the DTO pattern, you would also make use of DTO assemblers. The assemblers are used to create DTOs from Domain Objects, and vice versa.

The conversion from Domain Object to DTO and back again can be a costly process. If you're not creating a distributed application, you probably won't see any great benefits from the pattern, as Martin Fowler explains here

1. Open the file using vi myfile.csv
2. Press Escape
3. Type :%s/replaceme/withthis/
4. Type :wq and press Enter

Now you will have the new pattern in your file.

Use the %lf format specifier to read a double:

double a;
scanf("%lf",&a);

Wikipedia has a decent reference for available format specifiers.

You'll need to use the %lf format specifier to print out the results as well:

printf("%lf %lf",a,b);

At least for Ubuntu (maybe also others) works this (inspired by a previous post in this thread):

printf "Installed with pip:";
pip list 2>/dev/null | gawk '{print $1;}' | while read; do pip show "${REPLY}" 2>/dev/null | grep 'Location: /usr/local/lib/python2.7/dist-packages' >/dev/null; if (( $? == 0 )); then printf " ${REPLY}"; fi; done; echo

$('#toptitle').html('New world');

or

$('#toptitle').text('New world');

You need to escape the quotes in the string by adding a backslash \ before ".

Like:

"<font color=\"red\">"

Note that sometimes you will want to use the class type name inside its own definition, for example when using Python Typing module, e.g.

class Tree:
    def __init__(self, left: Tree, right: Tree):
        self.left = left
        self.right = right

This will also result in

NameError: name 'Tree' is not defined

That's because the class has not been defined yet at this point. The workaround is using so called Forward Reference, i.e. wrapping a class name in a string, i.e.

class Tree:
    def __init__(self, left: 'Tree', right: 'Tree'):

Try this code :)

Its an fully transparent hexa code - "#00000000"

Using mysql's ego command

From mysql's help command:

ego          (\G) Send command to mysql server, display result vertically.

So by appending a \G to your select, you can get a very clean vertical output:

mysql> SELECT * FROM sometable \G

Using a pager

You can tell MySQL to use the less pager with its -S option that chops wide lines and gives you an output that you can scroll with the arrow keys:

mysql> pager less -S

Thus, next time you run a command with a wide output, MySQL will let you browse the output with the less pager:

mysql> SELECT * FROM sometable;

If you're done with the pager and want to go back to the regular output on stdout, use this:

mysql> nopager

Use ng-value for set value of input box after clicking on a button:

"input type="email"  class="form-control" id="email2" ng-value="myForm.email2" placeholder="Email"

and

Set Value as:

 $scope.myForm.email2 = $scope.names[0].success;

If you're using bash you can just say

if grep -q "$SOURCE" <<< "$LIST" ; then
    ...
fi

You can split that string on , and directly get a list:

mStr = 'A,B,C,D,E'
list1 = mStr.split(',')
print(list1)

Output:

['A', 'B', 'C', 'D', 'E']

You can also convert it to an n-tuple:

print(tuple(list1))

Output:

('A', 'B', 'C', 'D', 'E')

The simplest fix is to make the comparator function be static:

static int comparator (const Bar & first, const Bar & second);
^^^^^^

When invoking it in Count, its name will be Foo::comparator.

The way you have it now, it does not make sense to be a non-static member function because it does not use any member variables of Foo.

Another option is to make it a non-member function, especially if it makes sense that this comparator might be used by other code besides just Foo.

On newer versions of Symfony2 (using a parameters.yml instead of parameters.ini), you can store objects or arrays instead of key-value pairs, so you can manage your globals this way:

config.yml (edited only once):

# app/config/config.yml
twig:
  globals:
    project: %project%

parameters.yml:

# app/config/parameters.yml
project:
  name:       myproject.com
  version:    1.1.42

And then in a twig file, you can use {{ project.version }} or {{ project.name }}.

Note: I personally dislike adding things to app, just because that's the Symfony's variable and I don't know what will be stored there in the future.

Use regular expressions. In this case, you can use gsub:

gsub("^.*?_","_","ATGAS_1121")
[1] "_1121"

This regular expression matches the beginning of the string (^), any character (.) repeated zero or more times (*), and underscore (_). The ? makes the match "lazy" so that it only matches are far as the first underscore. That match is replaced with just an underscore. See ?regex for more details and references

In you want to know the data from de selected row, you can try this snippet code:

DataGridView1.SelectedRows.Item(0).Cells(1).Value

Sub test()
    MsgBox Worksheets("sheet_name").Range("A65536").End(xlUp).Row
End Sub

This is looking for a value in column A because of "A65536".

This answer is for Ubuntu users looking for a solution without writing SQL queries.

The following is the initial screen you'll get after opening it

In the top right, where it says Administration, click in the arrow to the right

This will show Schema (instead of Administration) and it's possible to see a sys database.

Right click in the grey area after functions and click Create Schema...

This will open the following where I'm creating a table named StackOverflow_db

Clicking in the bottom right button that says "Apply",

And in this new view click in "Apply" too. In the end you'll get a database called StackOverflow_db

There is a constructor accepting two pointer parameters, so the code is simply

 std::string cppstr(cstr, cstr + min(max_length, strlen(cstr)));

this is also going to be as efficient as std::string cppstr(cstr) if the length is smaller than max_length.

The String class comes with the format abilities:

System.out.println(String.format("%02d", 5));

for full documentation, here is the doc

There are actually two ways of doing this:

1. st = "Line 1" + vbCrLf + "Line 2"

2. st = "Line 1" + vbNewLine + "Line 2"

These even work for message boxes (and all other places where strings are used).

Another point to keep in mind, be sure the referenced dlls are not installed in the GAC. After testing, I installed my dlls into the GAC to do system level testing. Later, when I had to debug my code again, I couldn't step into the referenced assemblies until I deleted them from the GAC.

the root directory (in PHP) is the directory of the file that is pinged. For example, I go to http://localhost/directory/to/file/index.php, the root directory will be "/dictory/to/file", since it's the one that you've made a web request for.

In my situation, I was comparing table schema column count for 2 identical tables in 2 databases; one is the main database and the other is the archival database. I did this (SQL 2012+):

DECLARE @colCount1 INT;
DECLARE @colCount2 INT;

SELECT @colCount1 = COUNT(COLUMN_NAME) FROM MainDB.INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'SomeTable';
SELECT @colCount2 = COUNT(COLUMN_NAME) FROM ArchiveDB.INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'SomeTable';

IF (@colCount1 != @colCount2) THROW 5000, 'Number of columns in both tables are not equal. The archive schema may need to be updated.', 16;

The important thing to notice here is qualifying the database name before INFORMATION_SCHEMA (which is a schema, like dbo). This will allow the code to break, in case columns were added to the main database and not to the archival database, in which if the procedure were allowed to run, data loss would almost certainly occur.

The other solution is attaching the image as attachment and then referencing it html code using cid.

HTML Code:

<html>
    <head>
    </head>
    <body>
        <img width=100 height=100 id="1" src="cid:Logo.jpg">
    </body>
</html>

C# Code:

EmailMessage email = new EmailMessage(service);
email.Subject = "Email with Image";
email.Body = new MessageBody(BodyType.HTML, html);
email.ToRecipients.Add("[email protected]");
string file = @"C:\Users\acv\Pictures\Logo.jpg";
email.Attachments.AddFileAttachment("Logo.jpg", file);
email.Attachments[0].IsInline = true;
email.Attachments[0].ContentId = "Logo.jpg";
email.SendAndSaveCopy();

There are several tools all built around Xperf. It's rather complex but very powerful -- see the quick start guide. There are other useful resources on the Windows Performance Analysis page

FacebookConnect or OpenID are two great options.

Basically, your users login to other sites they are already members of (Facebook, or Google), and then you get confirmation from that site telling you the user is trustworthy - start a session, and they're logged in. No database needed (unless you want to associate more data to their account).

You can try color-sampler. It's an easy way to pick color in a canvas. See demo.

Natively that is not possible, yet. See also this feature request.

So far you need to do that in your containers CMD to wait until all required services are there.

In the Dockerfiles CMD you could refer to your own start script that wraps starting up your container service. Before you start it, you wait for a depending one like:

Dockerfile

FROM python:2-onbuild
RUN ["pip", "install", "pika"]
ADD start.sh /start.sh
CMD ["/start.sh"]

start.sh

#!/bin/bash
while ! nc -z rabbitmq 5672; do sleep 3; done
python rabbit.py

Probably you need to install netcat in your Dockerfile as well. I do not know what is pre-installed on the python image.

There are a few tools out there that provide easy to use waiting logic, for simple tcp port checks:

• wait-for-it
• dockerize

For more complex waits:

• goss - Explanation blog

you can use this command

pg_dump --table=yourTable --data-only --column-inserts yourDataBase > file.sql

you should change yourTable, yourDataBase to your case

You were nearly there, need to use std::fixed as well, refer http://www.cplusplus.com/reference/iostream/manipulators/fixed/

#include <iostream>
#include <iomanip>

int main(int argc, char** argv)
{
    float testme[] = { 0.12345, 1.2345, 12.345, 123.45, 1234.5, 12345 };

    std::cout << std::setprecision(2) << std::fixed;

    for(int i = 0; i < 6; ++i)
    {
        std::cout << testme[i] << std::endl;
    }

    return 0;
}

outputs:

0.12
1.23
12.35
123.45
1234.50
12345.00

Use the awesome interactive rebase:

git rebase -i @~9   # Show the last 9 commits in a text editor

Find the commit you want, change pick to e (edit), and save and close the file. Git will rewind to that commit, allowing you to either:

• use git commit --amend to make changes, or
• use git reset @~ to discard the last commit, but not the changes to the files (i.e. take you to the point you were at when you'd edited the files, but hadn't committed yet).

The latter is useful for doing more complex stuff like splitting into multiple commits.

Then, run git rebase --continue, and Git will replay the subsequent changes on top of your modified commit. You may be asked to fix some merge conflicts.

Note: @ is shorthand for HEAD, and ~ is the commit before the specified commit.

Read more about rewriting history in the Git docs.

Don't be afraid to rebase

ProTip™:   Don't be afraid to experiment with "dangerous" commands that rewrite history* — Git doesn't delete your commits for 90 days by default; you can find them in the reflog:

$ git reset @~3   # go back 3 commits
$ git reflog
c4f708b HEAD@{0}: reset: moving to @~3
2c52489 HEAD@{1}: commit: more changes
4a5246d HEAD@{2}: commit: make important changes
e8571e4 HEAD@{3}: commit: make some changes
... earlier commits ...
$ git reset 2c52489
... and you're back where you started

* Watch out for options like --hard and --force though — they can discard data.
* Also, don't rewrite history on any branches you're collaborating on.

On many systems, git rebase -i will open up Vim by default. Vim doesn't work like most modern text editors, so take a look at how to rebase using Vim. If you'd rather use a different editor, change it with git config --global core.editor your-favorite-text-editor.

You're not inheriting from your base class:

public class Ext : Base {
    // constructor

    public override void Draw()
    {
    }
}

if your python version is 3.5, do a pip install mysqlclient, other things didn't work for me

The official list of current iOS Wi-Fi Management APIs

There is no Wi-Fi Direct type of connection available. The primary issue being that Apple does not allow programmatic setting of the Wi-Fi network SSID and password. However, this improves substantially in iOS 11 where you can at least prompt the user to switch to another WiFi network.

QA1942 - iOS Wi-Fi Management APIs

Entitlement option

This technology is useful if you want to provide a list of Wi-Fi networks that a user might want to connect to in a manager type app. It requires that you apply for this entitlement with Apple and the email address is in the documentation.

• NEHotspotHelper

MFi Program options

These technologies allow the accessory connect to the same network as the iPhone and are not for setting up a peer-to-peer connection.

• Wireless Accessory Configuration (WAC)
• HomeKit

Peer-to-peer between Apple devices

These APIs come close to what you want, but they're Apple-to-Apple only.

• NSNetService
• Multipeer Connectivity

WiTap Example Code

iOS 11 NEHotspotConfiguration

Brought up at WWDC 2017 Advances in Networking, Part 1 is NEHotspotConfiguration which allows the app to specify and prompt to connect to a specific network.

whilst sometimes you might have multiple php versions, you might also have a held-back version of php-mysql.. do a sudo dpkg -l | grep mysql | grep php and compare what you get from php -v

If you are serializing your data object, it will not be a proper json object. Take what you have, and just wrap the data object in a JSON.stringify().

$http({
    url: '/user_to_itsr',
    method: "POST",
    data: JSON.stringify({application:app, from:d1, to:d2}),
    headers: {'Content-Type': 'application/json'}
}).success(function (data, status, headers, config) {
    $scope.users = data.users; // assign  $scope.persons here as promise is resolved here 
}).error(function (data, status, headers, config) {
    $scope.status = status + ' ' + headers;
});

If available you can probe the current user account with posix_geteuid and then get the user name with posix_getpwuid.

$username = posix_getpwuid(posix_geteuid())['name'];

If you are running in safe mode however (which is often the case when exec is disabled), then it's unlikely that your PHP process is running under anything but the default www-data or apache account.

You may use fnDrawCallback or fnInfoCallback to detect changes, when next is clicked both of them are fired.

But beware, page changes are not the only source that can fire those callbacks.

In both cases yes it can, and this is the default behaviour for both IE and Edge.

The other answers add valuable insight but chiefly describe the behaviour in Chrome. it's important to note that the behaviour is completely different in IE. CMBuckley's very helpful test script demonstrates that in (say) Chrome, the cookies are not shared between root and subdomains when no domain is specified. However the same test in IE shows that they are shared. This IE case is closer to the take-home description in CMBuckley's www-or-not-www link. I know this to be the case because we have a system that used different servicestack cookies on both the root and subdomain. It all worked fine until someone accessed it in IE and the two systems fought over whose session cookie would win until we blew up the cache.

This depends on a lot of things, such as what is the size of the file, what is its type (text/binary) etc. Some time ago I benchmarked the following function against versions using streambuf iterators - it was about twice as fast:

unsigned int FileRead( std::istream & is, std::vector <char> & buff ) {
    is.read( &buff[0], buff.size() );
    return is.gcount();
}

void FileRead( std::ifstream & ifs, string & s ) {
    const unsigned int BUFSIZE = 64 * 1024; // reasoable sized buffer
    std::vector <char> buffer( BUFSIZE );

    while( unsigned int n = FileRead( ifs, buffer ) ) {
        s.append( &buffer[0], n );
    }
}

The simplest way to display last element in python is

>>> list[-1:] # returns indexed value
    [3]
>>> list[-1]  # returns value
    3

there are many other method to achieve such a goal but these are short and sweet to use.

Procedural style :

echo date_format(date_create('17 Oct 2008'), 'c');
// Output : 2008-10-17T00:00:00+02:00

Object oriented style :

$formatteddate = new DateTime('17 Oct 2008');
echo $datetime->format('c');
// Output : 2008-10-17T00:00:00+02:00

Hybrid 1 :

echo date_format(new DateTime('17 Oct 2008'), 'c');
// Output : 2008-10-17T00:00:00+02:00

Hybrid 2 :

echo date_create('17 Oct 2008')->format('c');
// Output : 2008-10-17T00:00:00+02:00

Notes :

1) You could also use 'Y-m-d\TH:i:sP' as an alternative to 'c' for your format.

2) The default time zone of your input is the time zone of your server. If you want the input to be for a different time zone, you need to set your time zone explicitly. This will also impact your output, however :

echo date_format(date_create('17 Oct 2008 +0800'), 'c');
// Output : 2008-10-17T00:00:00+08:00

3) If you want the output to be for a time zone different from that of your input, you can set your time zone explicitly :

echo date_format(date_create('17 Oct 2008')->setTimezone(new DateTimeZone('America/New_York')), 'c');
// Output : 2008-10-16T18:00:00-04:00

you may try the TO_CHAR function to convert the result

e.g.

SELECT TO_CHAR(92, '99.99') AS RES FROM DUAL

SELECT TO_CHAR(92.258, '99.99') AS RES FROM DUAL

Hope it helps

After review the problem, here is my delphi way, that may help

var
A: Array of Integer;
I,J,C,K, P: Integer;
begin
C:=10;
SetLength(A,10);
A[0]:=1; A[1]:=4; A[2]:=2; A[3]:=6; A[4]:=3; A[5]:=4;
A[6]:=3; A[7]:=4; A[8]:=2; A[9]:=5;

for I := 0 to C-1 do
begin
  for J := I+1 to C-1 do
    if A[I]=A[J] then
    begin
      for K := C-1 Downto J do
        if A[J]<>A[k] then
        begin
          P:=A[K];
          A[K]:=0;
          A[J]:=P;
          C:=K;
          break;
        end
        else
        begin
          A[K]:=0;
          C:=K;
        end;
    end;
end;

//tructate array
setlength(A,C);
end;

Another option, once inside the GDB shell, before running the program, you can do

(gdb) set args file1 file2

and inspect it with:

(gdb) show args

In C++ a class with at least one pure virtual function is called abstract class. You can not create objects of that class, but may only have pointers or references to it.

If you are deriving from an abstract class, then make sure you override and define all pure virtual functions for your class.

From your snippet Your class AliceUniversity seems to be an abstract class. It needs to override and define all the pure virtual functions of the classes Graduate and UniversityGraduate.

Pure virtual functions are the ones with = 0; at the end of declaration.

Example: virtual void doSomething() = 0;

For a specific answer, you will need to post the definition of the class for which you get the error and the classes from which that class is deriving.

You don't need a generate bock if you want all the bits of temp assigned in the same always block.

parameter ROWBITS = 4;
reg [ROWBITS-1:0] temp;
always @(posedge sysclk) begin
    for (integer c=0; c<ROWBITS; c=c+1) begin: test
        temp[c] <= 1'b0;
    end
end

Alternatively, if your simulator supports IEEE 1800 (SytemVerilog), then

parameter ROWBITS = 4;
reg [ROWBITS-1:0] temp;
always @(posedge sysclk) begin
        temp <= '0; // fill with 0
    end
end

Given the following sample

myData <- data.frame(A=rep(1:2, 3), B=rep(1:3, 2), Pulse=20:25)  

then

myData$A <-as.factor(myData$A)
myData$B <-as.factor(myData$B)

or you could select your columns altogether and wrap it up nicely:

# select columns
cols <- c("A", "B")
myData[,cols] <- data.frame(apply(myData[cols], 2, as.factor))

levels(myData$A) <- c("long", "short")
levels(myData$B) <- c("1kg", "2kg", "3kg")

To obtain

> myData
      A   B Pulse
1  long 1kg    20
2 short 2kg    21
3  long 3kg    22
4 short 1kg    23
5  long 2kg    24
6 short 3kg    25

It is true that a java class can implement multiple interfaces at the same time, but there is a catch here. If in a class, you are trying to implement two java interfaces, which contains methods with same signature but diffrent return type, in that case you will get compilation error.

interface One
{
    int m1();
}
interface Two
{
    float m1();
}
public class MyClass implements One, Two{
    int m1() {}
    float m1() {}
    public static void main(String... args) {

    }
}

output :

prog.java:14: error: method m1() is already defined in class MyClass
    public float m1() {}
                 ^
prog.java:11: error: MyClass is not abstract and does not override abstract method m1() in Two
public class MyClass implements One, Two{

I like the top-voted answer by Dan McNevin. I ended up doing the sequence of git commands too many times and decided to make a script. So here it is:

#!/bin/bash

The script only requires a project name. It will generate a git repository in ~/Dropbox/git/ under the specified name and will push the entire contents of the current directory to the newly created origin master branch. If more than one project name is given, the right-most project name argument will be used.

Optionally, the -r command argument specifies the remote branch that will push to the origin master. The location of the project origin master can also be specified with the -m argument. A default .gitignore file is also placed in the remote branch directory. The directory and .gitignore file defaults are specified in the script.

The .browser call has been removed in jquery 1.9 have a look at http://jquery.com/upgrade-guide/1.9/ for more details.

This is the classic "unicode issue". I believe that explaining this is beyond the scope of a StackOverflow answer to completely explain what is happening.

It is well explained here.

In very brief summary, you have passed something that is being interpreted as a string of bytes to something that needs to decode it into Unicode characters, but the default codec (ascii) is failing.

The presentation I pointed you to provides advice for avoiding this. Make your code a "unicode sandwich". In Python 2, the use of from __future__ import unicode_literals helps.

Update: how can the code be fixed:

OK - in your variable "source" you have some bytes. It is not clear from your question how they got in there - maybe you read them from a web form? In any case, they are not encoded with ascii, but python is trying to convert them to unicode assuming that they are. You need to explicitly tell it what the encoding is. This means that you need to know what the encoding is! That is not always easy, and it depends entirely on where this string came from. You could experiment with some common encodings - for example UTF-8. You tell unicode() the encoding as a second parameter:

source = unicode(source, 'utf-8')

Need to Update

Android SDK : SDK Tools -> Support Repository -> Google Repository

After updating the Android SDK need to sync gradle build in Android studio.

TL;DR: sleep infinity actually sleeps the maximum time allowed, which is finite.

Wondering why this is not documented anywhere, I bothered to read the sources from GNU coreutils and I found it executes roughly what follows:

1. Use strtod from C stdlib on the first argument to convert 'infinity' to a double precision value. So, assuming IEEE 754 double precision the 64-bit positive infinity value is stored in the seconds variable.
2. Invoke xnanosleep(seconds) (found in gnulib), this in turn invokes dtotimespec(seconds) (also in gnulib) to convert from double to struct timespec.
3. struct timespec is just a pair of numbers: integer part (in seconds) and fractional part (in nanoseconds). Naïvely converting positive infinity to integer would result in undefined behaviour (see §6.3.1.4 from C standard), so instead it truncates to TYPE_MAXIMUM(time_t).
4. The actual value of TYPE_MAXIMUM(time_t) is not set in the standard (even sizeof(time_t) isn't); so, for the sake of example let's pick x86-64 from a recent Linux kernel.

This is TIME_T_MAX in the Linux kernel, which is defined (time.h) as:

(time_t)((1UL << ((sizeof(time_t) << 3) - 1)) - 1)

Note that time_t is __kernel_time_t and time_t is long; the LP64 data model is used, so sizeof(long) is 8 (64 bits).

Which results in: TIME_T_MAX = 9223372036854775807.

That is: sleep infinite results in an actual sleep time of 9223372036854775807 seconds (10^11 years). And for 32-bit linux systems (sizeof(long) is 4 (32 bits)): 2147483647 seconds (68 years; see also year 2038 problem).

Edit: apparently the nanoseconds function called is not directly the syscall, but an OS-dependent wrapper (also defined in gnulib).

There's an extra step as a result: for some systems where HAVE_BUG_BIG_NANOSLEEP is true the sleep is truncated to 24 days and then called in a loop. This is the case for some (or all?) Linux distros. Note that this wrapper may be not used if a configure-time test succeeds (source).

In particular, that would be 24 * 24 * 60 * 60 = 2073600 seconds (plus 999999999 nanoseconds); but this is called in a loop in order to respect the specified total sleep time. Therefore the previous conclusions remain valid.

In conclusion, the resulting sleep time is not infinite but high enough for all practical purposes, even if the resulting actual time lapse is not portable; that depends on the OS and architecture.

To answer the original question, this is obviously good enough but if for some reason (a very resource-constrained system) you really want to avoid an useless extra countdown timer, I guess the most correct alternative is to use the cat method described in other answers.

Edit: recent GNU coreutils versions will try to use the pause syscall (if available) instead of looping. The previous argument is no longer valid when targeting these newer versions in Linux (and possibly BSD).

Portability

This is an important valid concern:

• sleep infinity is a GNU coreutils extension not contemplated in POSIX. GNU's implementation also supports a "fancy" syntax for time durations, like sleep 1h 5.2s while POSIX only allows a positive integer (e.g. sleep 0.5 is not allowed).
• Some compatible implementations: GNU coreutils, FreeBSD (at least from version 8.2?), Busybox (requires to be compiled with options FANCY_SLEEP and FLOAT_DURATION).
• The strtod behaviour is C and POSIX compatible (i.e. strtod("infinity", 0) is always valid in C99-conformant implementations, see §7.20.1.3).

Hack grep's color function, and count how many color tags it prints out:

echo -e "a\nb  b b\nc\ndef\nb e brb\nr" \
| GREP_COLOR="033" grep --color=always  b \
| perl -e 'undef $/; $_=<>; s/\n//g; s/\x1b\x5b\x30\x33\x33/\n/g; print $_' \
| wc -l

When I first came from Java to Python I hated this. It scared me to death.

Today it might just be the one thing I love most about Python.

I love being on a platform, where people trust each other and don't feel like they need to build impenetrable walls around their code. In strongly encapsulated languages, if an API has a bug, and you have figured out what goes wrong, you may still be unable to work around it because the needed method is private. In Python the attitude is: "sure". If you think you understand the situation, perhaps you have even read it, then all we can say is "good luck!".

Remember, encapsulation is not even weakly related to "security", or keeping the kids off the lawn. It is just another pattern that should be used to make a code base easier to understand.

Can't be sure if this applied to SQL Server Express, but you can still access the "before" data even if your trigger is happening AFTER the update. You need to read the data from either the deleted or inserted table that is created on the fly when the table is changed. This is essentially what @Stamen says, but I still needed to explore further to understand that (helpful!) answer.

The deleted table stores copies of the affected rows during DELETE and UPDATE statements. During the execution of a DELETE or UPDATE statement, rows are deleted from the trigger table and transferred to the deleted table...

The inserted table stores copies of the affected rows during INSERT and UPDATE statements. During an insert or update transaction, new rows are added to both the inserted table and the trigger table...

https://msdn.microsoft.com/en-us/library/ms191300.aspx

So you can create your trigger to read data from one of those tables, e.g.

CREATE TRIGGER <TriggerName> ON <TableName>
AFTER UPDATE
AS
  BEGIN
    INSERT INTO <HistoryTable> ( <columns...>, DateChanged )
    SELECT <columns...>, getdate()
    FROM deleted;
  END;

My example is based on the one here:

You'll need to issue two commands:

1. git fetch origin
2. git status

To activate the installRelease task, you simply need a signingConfig. That is all.

From http://tools.android.com/tech-docs/new-build-system/user-guide#TOC-Android-tasks:

Finally, the plugin creates install/uninstall tasks for all build types (debug, release, test), as long as they can be installed (which requires signing).

Here is what you want:

Install tasks
-------------
installDebug - Installs the Debug build
installDebugTest - Installs the Test build for the Debug build
installRelease - Installs the Release build
uninstallAll - Uninstall all applications.
uninstallDebug - Uninstalls the Debug build
uninstallDebugTest - Uninstalls the Test build for the Debug build
uninstallRelease - Uninstalls the Release build   <--- release

Here is how to obtain the installRelease task:

Example build.gradle:

buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:1.2.3'
    }
}

apply plugin: 'com.android.application'

android {
  compileSdkVersion 22
  buildToolsVersion '22.0.1'

  defaultConfig {
    applicationId 'demo'
    minSdkVersion 15
    targetSdkVersion 22
    versionCode 1
    versionName '1.0'
  }

  signingConfigs {
      release {
          storeFile <file>
          storePassword <password>
          keyAlias <alias>
          keyPassword <password>
      }
  }

  buildTypes {
    release {
        signingConfig signingConfigs.release
    }
  }
}

redis-cli -h XXX.XXX.XXX.XXX -p YYYY

xxx.xxx.xxx.xxx is the IP address and yyyy is the port

EXAMPLE from my dev environment

redis-cli -h 10.144.62.3 -p 30000

REDIS CLI COMMANDS

Host, port, password and database By default redis-cli connects to the server at 127.0.0.1 port 6379. As you can guess, you can easily change this using command line options. To specify a different host name or an IP address, use -h. In order to set a different port, use -p.

redis-cli -h redis15.localnet.org -p 6390 ping

Answer

You have multiple options:

1. background-size: 100% 100%; - image gets stretched (aspect ratio may be preserved, depending on browser)
2. background-size: contain; - image is stretched without cutting it while preserving aspect ratio
3. background-size: cover; - image is completely covering the element while preserving aspect ratio (image can be cut off)

I created a custom class MyButton extended from UIButton. Then added this inside the Identity Inspector:

After this, change the button type to Custom:

Then you can set attributes like textColor and UIFont for your UIButton for the different states:

Then I also created two methods inside MyButton class which I have to call inside my code when I want a UIButton to be displayed as highlighted:

- (void)changeColorAsUnselection{
    [self setTitleColor:[UIColor colorFromHexString:acColorGreyDark] 
               forState:UIControlStateNormal & 
                        UIControlStateSelected & 
                        UIControlStateHighlighted];
}

- (void)changeColorAsSelection{
    [self setTitleColor:[UIColor colorFromHexString:acColorYellow] 
               forState:UIControlStateNormal & 
                        UIControlStateHighlighted & 
                        UIControlStateSelected];
}

You have to set the titleColor for normal, highlight and selected UIControlState because there can be more than one state at a time according to the documentation of UIControlState. If you don't create these methods, the UIButton will display selection or highlighting but they won't stay in the UIColor you setup inside the UIInterface Builder because they are just available for a short display of a selection, not for displaying selection itself.

Try this one, should work:

cast((convert(bigint,b.tax_id)) as varchar(20))

Approach: 1

Given original string format: 2019/03/04 00:08:48

you can use

updated_df = df['timestamp'].astype('datetime64[ns]')

The result will be in this datetime format: 2019-03-04 00:08:48

Approach: 2

updated_df = df.astype({'timestamp':'datetime64[ns]'})

I would try this first

select * from employee where month(current_date)-3 = month(joining_date)

It sounds like you are doing everything exactly as the client credential section of the Subversion book suggests. The only thing I can think of is that the server isn't asking for the username and password because is getting it from somewhere else.

Add the active: false option (documentation)..

$("#accordion").accordion({ header: "h3", collapsible: true, active: false });

Robby Pond's answer can be generalized to use JAVA_HOME environment variable and to also compensate for any blanks that might occur in the path (like Program Files):

"%JAVA_HOME%\bin\keytool" -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64

To find the item that has a name, should I just use a for loop, and when the item is found, return the element position in the ArrayList?

Yes to the loop (either using indexes or an Iterator). On the return value, either return its index, or the item iteself, depending on your needs. ArrayList doesn't have an indexOf(Object target, Comparator compare)` or similar. Now that Java is getting lambda expressions (in Java 8, ~March 2014), I expect we'll see APIs get methods that accept lambdas for things like this.
