Most Android and iPhone apps I have seen use an initial screen or dialog box to ask for credentials. I think it is cumbersome for the user to have to re-enter their name/password often, so storing that info makes sense from a usability perspective.

The advice from the (Android dev guide) is:

In general, we recommend minimizing the frequency of asking for user credentials -- to make phishing attacks more conspicuous, and less likely to be successful. Instead use an authorization token and refresh it.

Where possible, username and password should not be stored on the device. Instead, perform initial authentication using the username and password supplied by the user, and then use a short-lived, service-specific authorization token.

Using the AccountManger is the best option for storing credentials. The SampleSyncAdapter provides an example of how to use it.

If this is not an option to you for some reason, you can fall back to persisting credentials using the Preferences mechanism. Other applications won't be able to access your preferences, so the user's information is not easily exposed.

sys.argv is the list of arguments passed to the Python program. The first argument, sys.argv[0], is actually the name of the program as it was invoked. That's not a Python thing, but how most operating systems work. The reason sys.argv[0] exists is so you can change your program's behaviour depending on how it was invoked. sys.argv[1] is thus the first argument you actually pass to the program.

Because lists (like most sequences) in Python start indexing at 0, and because indexing past the end of the list is an error, you need to check if the list has length 2 or longer before you can access sys.argv[1].

The problem lies in:

$query = $this->db->conn->prepare('SELECT value, param FROM ws_settings WHERE name = ?');
$query->bind_param('s', $setting);

The prepare() method can return false and you should check for that. As for why it returns false, perhaps the table name or column names (in SELECT or WHERE clause) are not correct?

Also, consider use of something like $this->db->conn->error_list to examine errors that occurred parsing the SQL. (I'll occasionally echo the actual SQL statement strings and paste into phpMyAdmin to test, too, but there's definitely something failing there.)

If xamp already installed on your computer user these settings

As the error information said first please try to increase the timeout value in the both the client side and service side as following:

<basicHttpBinding>
    <binding name="basicHttpBinding_ACRMS" maxBufferSize="2147483647"
      maxReceivedMessageSize="2147483647"
      openTimeout="00:20:00" 
      receiveTimeout="00:20:00" closeTimeout="00:20:00"
      sendTimeout="00:20:00">
      <readerQuotas maxDepth="32" maxStringContentLength="2097152"
        maxArrayLength="2097152" maxBytesPerRead="4006" maxNameTableCharCount="16384" />
    </binding>

Then please do not forget to apply this binding configuration to the endpoint by doing the following:

<endpoint address="" binding="basicHttpBinding" 
      bindingConfiguration="basicHttpBinding_ACRMS"
      contract="MonitorRAM.IService1" />

If the above can not help, it will be better if you can try to upload your main project here, then I want to have a test in my side.

In my case, inside a Spring4 Application, i had to use a classic Abstract Factory Pattern(for which i took the idea from - http://java-design-patterns.com/patterns/abstract-factory/) to create instances each and every time there was a operation to be done.So my code was to be designed like:

public abstract class EO {
    @Autowired
    protected SmsNotificationService smsNotificationService;
    @Autowired
    protected SendEmailService sendEmailService;
    ...
    protected abstract void executeOperation(GenericMessage gMessage);
}

public final class OperationsExecutor {
    public enum OperationsType {
        ENROLL, CAMPAIGN
    }

    private OperationsExecutor() {
    }

    public static Object delegateOperation(OperationsType type, Object obj) 
    {
        switch(type) {
            case ENROLL:
                if (obj == null) {
                    return new EnrollOperation();
                }
                return EnrollOperation.validateRequestParams(obj);
            case CAMPAIGN:
                if (obj == null) {
                    return new CampaignOperation();
                }
                return CampaignOperation.validateRequestParams(obj);
            default:
                throw new IllegalArgumentException("OperationsType not supported.");
        }
    }
}

@Configurable(dependencyCheck = true)
public class CampaignOperation extends EO {
    @Override
    public void executeOperation(GenericMessage genericMessage) {
        LOGGER.info("This is CAMPAIGN Operation: " + genericMessage);
    }
}

Initially to inject the dependencies in the abstract class I tried all stereotype annotations like @Component, @Service etc but even though Spring context file had ComponentScanning for the entire package, but somehow while creating instances of Subclasses like CampaignOperation, the Super Abstract class EO was having null for its properties as spring was unable to recognize and inject its dependencies.After much trial and error I used this **@Configurable(dependencyCheck = true)** annotation and finally Spring was able to inject the dependencies and I was able to use the properties in the subclass without cluttering them with too many properties.

<context:annotation-config />
<context:component-scan base-package="com.xyz" />

This way is much simple...

<form [formGroup]="form" (keyup.enter)="yourMethod(form.value)">

</form>

Add store name to template like {% url 'app_name:url_name' %}

App_name = store

In urls.py, path('search', views.searched, name="searched"),

<form action="{% url 'store:searched' %}" method="POST">

You can try this with by adding backticks on whole url

style={{backgroundImage:url(${val.image || 'http://max-themes.net/demos/grandtour/upload/Tokyo_Dollarphotoclub_72848283-copy-700x466.jpg'} ) }}

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

In your controller, render the new action from your create action if validation fails, with an instance variable, @car populated from the user input (i.e., the params hash). Then, in your view, add a logic check (either an if block around the form or a ternary on the helpers, your choice) that automatically sets the value of the form fields to the params values passed in to @car if car exists. That way, the form will be blank on first visit and in theory only be populated on re-render in the case of error. In any case, they will not be populated unless @car is set.

I have same problem. It just the javascript's script loads too fast--before the HTML's element loaded. So the browser returning null, since the browser can't find where is the element you like to manipulate.

But this returns some nonsense value that if I get two timestamps, the second one can be smaller or bigger than the first (second one should always be bigger).

What makes you think that? The value is probably OK. It’s the same situation as with seconds and minutes – when you measure time in minutes and seconds, the number of seconds rolls over to zero when it gets to sixty.

To convert the returned value into a “linear” number you could multiply the number of seconds and add the microseconds. But if I count correctly, one year is about 1e6*60*60*24*360 µsec and that means you’ll need more than 32 bits to store the result:

$ perl -E '$_=1e6*60*60*24*360; say int log($_)/log(2)'
44

That’s probably one of the reasons to split the original returned value into two pieces.

You have here available an example of DNS Caching in Debian using dnsmasq.

Configuration summary:

/etc/default/dnsmasq

# Ensure you add this line
DNSMASQ_OPTS="-r /etc/resolv.dnsmasq"

/etc/resolv.dnsmasq

# Your preferred servers
nameserver 1.1.1.1
nameserver 8.8.8.8
nameserver 2001:4860:4860::8888

/etc/resolv.conf

nameserver 127.0.0.1

Then just restart dnsmasq.

Benchmark test using DNS 1.1.1.1:

for i in {1..100}; do time dig slashdot.org @1.1.1.1; done 2>&1 | grep ^real | sed -e s/.*m// | awk '{sum += $1} END {print sum / NR}'

Benchmark test using you local cached DNS:

for i in {1..100}; do time dig slashdot.org; done 2>&1 | grep ^real | sed -e s/.*m// | awk '{sum += $1} END {print sum / NR}'

I had the same issue but none of the above worked for mine. either there was a backstack problem (after loading when user pressed back it would to go the same fragment again) or it didnt call the onCreaetView

finally i did this:

public void transactFragment(Fragment fragment, boolean reload) {
    FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
    transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
    if (reload) {
        getSupportFragmentManager().popBackStack();
    }
    transaction.replace(R.id.main_activity_frame_layout, fragment);
    transaction.addToBackStack(null);
    transaction.commit();
}

good point is you dont need the tag or id of the fragment either. if you want to reload

To do this, I had to come up with an intermediate data structure:

class KeyDataPoint {
    String key;
    DateTime timestamp;
    Number data;
    // obvious constructor and getters
}

With this in place, the approach is to "flatten" each MultiDataPoint into a list of (timestamp, key, data) triples and stream together all such triples from the list of MultiDataPoint.

Then, we apply a groupingBy operation on the string key in order to gather the data for each key together. Note that a simple groupingBy would result in a map from each string key to a list of the corresponding KeyDataPoint triples. We don't want the triples; we want DataPoint instances, which are (timestamp, data) pairs. To do this we apply a "downstream" collector of the groupingBy which is a mapping operation that constructs a new DataPoint by getting the right values from the KeyDataPoint triple. The downstream collector of the mapping operation is simply toList which collects the DataPoint objects of the same group into a list.

Now we have a Map<String, List<DataPoint>> and we want to convert it to a collection of DataSet objects. We simply stream out the map entries and construct DataSet objects, collect them into a list, and return it.

The code ends up looking like this:

Collection<DataSet> convertMultiDataPointToDataSet(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .flatMap(mdp -> mdp.getData().entrySet().stream()
                           .map(e -> new KeyDataPoint(e.getKey(), mdp.getTimestamp(), e.getValue())))
        .collect(groupingBy(KeyDataPoint::getKey,
                    mapping(kdp -> new DataPoint(kdp.getTimestamp(), kdp.getData()), toList())))
        .entrySet().stream()
        .map(e -> new DataSet(e.getKey(), e.getValue()))
        .collect(toList());
}

I took some liberties with constructors and getters, but I think they should be obvious.

I am breaking the news to you. You CAN'T send an email with JavaScript per se.

Based on the context of the OP's question, my answer above does not hold true anymore as pointed out by @KennyEvitt in the comments. Looks like you can use JavaScript as an SMTP client.

However, I have not digged deeper to find out if it's secure & cross-browser compatible enough. So, I can neither encourage nor discourage you to use it. Use at your own risk.

f=open('list1.txt')  
f1=open('output.txt','a')
for x in f.readlines():
    f1.write(x)
f.close()
f1.close()

this will work 100% try this once

This one works in iOS and Safari.

You need to use Stoive's ArrayBuffer solution but you can't use BlobBuilder, as vava720 indicates, so here's the mashup of both.

function dataURItoBlob(dataURI) {
    var byteString = atob(dataURI.split(',')[1]);
    var ab = new ArrayBuffer(byteString.length);
    var ia = new Uint8Array(ab);
    for (var i = 0; i < byteString.length; i++) {
        ia[i] = byteString.charCodeAt(i);
    }
    return new Blob([ab], { type: 'image/jpeg' });
}

You need to do this:

var scope = {
     splitterStyle: {
         height: 100
     }
};

And then apply this styling to the required elements:

<div id="horizontal" style={splitterStyle}>

In your code you are doing this (which is incorrect):

<div id="horizontal" style={height}>

Where height = 100.

To complement the other answers: if you want to reset all background properties to their initial value (which includes background-color: transparent and background-image: none) without explicitly specifying any value such as transparent or none, you can do so by writing:

background: initial;

Have a look at Styled Button it will surely help you. There are lots examples please search on INTERNET.

eg:style

<style name="Widget.Button" parent="android:Widget">
    <item name="android:background">@drawable/red_dot</item>
</style>

you can use your selector instead of red_dot

red_dot:

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval"  >

    <solid android:color="#f00"/>
    <size android:width="55dip"
        android:height="55dip"/>
</shape>

Button:

<Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="49dp"
        style="@style/Widget.Button"
        android:text="Button" />

Change your || to && so it will only exit if the answer is NEITHER "AM" nor "PM".

Maybe you're in the wrong perspective?

Eclipse has a construct called a "perspective"; it's a task-oriented arrangement of windows, toolbar buttons, and menus. There's a Java perspective, a Debug perspective, there's probably a PHP perspective, etc. If you're not in the Java perspective, you won't see some of the buttons you expect (like New Class).

To switch perspectives, see the long-ish buttons on the right side of the toolbar, or use the Window menu.

$mail = new PHPMailer();

$mail->AddAddress($email); 
$mail->From     = $from;
$mail->Subject  = $subject; 
$mail->Body     = $body;

if($mail->Send()){
    echo 'Email Successfully Sent!';
}else{
    echo 'Email Sending Failed!';
}

the simplest way to handle email sending successful or failed...

Possibly the easiest way to make PHP perform a POST request is to use cURL, either as an extension or simply shelling out to another process. Here's a post sample:

// where are we posting to?
$url = 'http://foo.com/script.php';

// what post fields?
$fields = array(
   'field1' => $field1,
   'field2' => $field2,
);

// build the urlencoded data
$postvars = http_build_query($fields);

// open connection
$ch = curl_init();

// set the url, number of POST vars, POST data
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, count($fields));
curl_setopt($ch, CURLOPT_POSTFIELDS, $postvars);

// execute post
$result = curl_exec($ch);

// close connection
curl_close($ch);

Also check out Zend_Http set of classes in the Zend framework, which provides a pretty capable HTTP client written directly in PHP (no extensions required).

2014 EDIT - well, it's been a while since I wrote that. These days it's worth checking Guzzle which again can work with or without the curl extension.

If you want to use the new android.support.v7.app.AlertDialog and have different colors for the buttons and also have a custom layout then have a look at my https://gist.github.com/JoachimR/6bfbc175d5c8116d411e

@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

    View v = inflater.inflate(R.layout.custom_layout, null);

    initDialogUi(v);

    final AlertDialog d = new AlertDialog.Builder(activity, R.style.AppCompatAlertDialogStyle)
            .setTitle(getString(R.string.some_dialog_title))
            .setCancelable(true)
            .setPositiveButton(activity.getString(R.string.some_dialog_title_btn_positive),
                    new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            doSomething();
                            dismiss();
                        }
                    })
            .setNegativeButton(activity.getString(R.string.some_dialog_title_btn_negative),
                    new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            dismiss();
                        }
                    })
            .setView(v)
            .create();

    // change color of positive button         
    d.setOnShowListener(new DialogInterface.OnShowListener() {
        @Override
        public void onShow(DialogInterface dialog) {
            Button b = d.getButton(DialogInterface.BUTTON_POSITIVE);
            b.setTextColor(getResources().getColor(R.color.colorPrimary));
        }
    });

    return d;
}

You could use the PEAR Mail classes and methods, which allows you to check for errors via:

if (PEAR::isError($mail)) {
    echo("<p>" . $mail->getMessage() . "</p>");
} else {
    echo("<p>Message successfully sent!</p>");
}

You can find an example here.

I just ran into this problem. When I ran npm start, I got a bunch of duplicate identifier errors.

SOLUTION:

From the project root folder run:

rm -r typings
typings install
npm start

and everything works fine.

1. You can iterate using the index access,

2. To avoid O(n^2) complexity you can use two indices, i - current testing index, j - index to store next item and at the end of the cycle new size of the vector.

code:

void erase(std::vector<int>& v, int num)
{
  size_t j = 0;
  for (size_t i = 0; i < v.size(); ++i) {
    if (v[i] != num) v[j++] = v[i];
  }
  // trim vector to new size
  v.resize(j);
}

In such case you have no invalidating of iterators, complexity is O(n), and code is very concise and you don't need to write some helper classes, although in some case using helper classes can benefit in more flexible code.

This code does not use erase method, but solves your task.

Using pure stl you can do this in the following way (this is similar to the Motti's answer):

#include <algorithm>

void erase(std::vector<int>& v, int num) {
    vector<int>::iterator it = remove(v.begin(), v.end(), num);
    v.erase(it, v.end());
}

The reason why this is happening is because you have a folder that is already being tracked by Git inside another folder that is also tracked by Git. For example, I had a project and I added a subfolder to it. Both of them were being tracked by Git before I put one inside the other. In order to stop tracking the one inside, find it and remove the Git file with:

rm -rf .git

In my case I had a WordPress application and the folder I added inside was a theme. So I had to go to the theme root, and remove the Git file, so that the whole project would now be tracked by the parent, the WordPress application.

Operations on integers are exact. double is a floating point data type, and floating point operations are approximate whenever there's a fraction.

double also takes up twice as much space as int in many implementations (e.g. most 32-bit systems) .

I had to delete all the provisioning profiles by following this article.

I'm not amazing at PHP, but I think this is what you do:

$password = md5($password)

and $password would be the $_POST['password'] or whatever

Backbone was created by Jeremy Ashkenas who also wrote CoffeeScript. As a JavaScript-heavy application, what we now know as Backbone was responsible for structuring the application into a coherent code base. Underscore.js, backbone's only dependency, was also part of the DocumentCloud application.

Backbone helps developers manage a data model in their client-side web app with as much discipline and structure as you would get in traditional server-side application logic.

Additional benefits of using Backbone.js

1. See Backbone as a library, not as a framework
2. Javascript is now getting organized in a structured way, the (MVVM) Model
3. Large user community

While astype is probably the "best" option there are several other ways to convert it to an integer array. I'm using this arr in the following examples:

>>> import numpy as np
>>> arr = np.array([1,2,3,4], dtype=float)
>>> arr
array([ 1.,  2.,  3.,  4.])

The int* functions from NumPy

>>> np.int64(arr)
array([1, 2, 3, 4])

>>> np.int_(arr)
array([1, 2, 3, 4])

The NumPy *array functions themselves:

>>> np.array(arr, dtype=int)
array([1, 2, 3, 4])

>>> np.asarray(arr, dtype=int)
array([1, 2, 3, 4])

>>> np.asanyarray(arr, dtype=int)
array([1, 2, 3, 4])

The astype method (that was already mentioned but for completeness sake):

>>> arr.astype(int)
array([1, 2, 3, 4])

Note that passing int as dtype to astype or array will default to a default integer type that depends on your platform. For example on Windows it will be int32, on 64bit Linux with 64bit Python it's int64. If you need a specific integer type and want to avoid the platform "ambiguity" you should use the corresponding NumPy types like np.int32 or np.int64.

Spring Boot v2 Gradle plugin docs provide an answer:

6.1. Passing arguments to your application

Like all JavaExec tasks, arguments can be passed into bootRun from the command line using --args='<arguments>' when using Gradle 4.9 or later.

To run server with active profile set to dev:

$ ./gradlew bootRun --args='--spring.profiles.active=dev'

Base URL in JavaScript

You can access the current url quite easily in JavaScript with window.location

You have access to the segments of that URL via this locations object. For example:

// This article:
// https://stackoverflow.com/questions/21246818/how-to-get-the-base-url-in-javascript

var base_url = window.location.origin;
// "http://stackoverflow.com"

var host = window.location.host;
// stackoverflow.com

var pathArray = window.location.pathname.split( '/' );
// ["", "questions", "21246818", "how-to-get-the-base-url-in-javascript"]

In Chrome Dev Tools, you can simply enter window.location in your console and it will return all of the available properties.

Matplotlib uses a dictionary from its colors.py module.

To print the names use:

# python2:

import matplotlib
for name, hex in matplotlib.colors.cnames.iteritems():
    print(name, hex)

# python3:

import matplotlib
for name, hex in matplotlib.colors.cnames.items():
    print(name, hex)

This is the complete dictionary:

cnames = {
'aliceblue':            '#F0F8FF',
'antiquewhite':         '#FAEBD7',
'aqua':                 '#00FFFF',
'aquamarine':           '#7FFFD4',
'azure':                '#F0FFFF',

You could plot them like this:

import matplotlib.pyplot as plt
import matplotlib.patches as patches
import matplotlib.colors as colors
import math


fig = plt.figure()
ax = fig.add_subplot(111)

ratio = 1.0 / 3.0
count = math.ceil(math.sqrt(len(colors.cnames)))
x_count = count * ratio
y_count = count / ratio
x = 0
y = 0
w = 1 / x_count
h = 1 / y_count

for c in colors.cnames:
    pos = (x / x_count, y / y_count)
    ax.add_patch(patches.Rectangle(pos, w, h, color=c))
    ax.annotate(c, xy=pos)
    if y >= y_count-1:
        x += 1
        y = 0
    else:
        y += 1

plt.show()

You could try something like grep -R search . | grep -v '^node_modules/.*'

Do this:

$checksum = "my value"; 
header("Location: recordupdated.php?checksum=$checksum");

I was having trouble with mobile touchscreen button styling. This will fix your hover-stick / active button problems.

body, html {
  width: 600px;
}
p {
  font-size: 20px;
}

button {
  border: none;
  width: 200px;
  height: 60px;
  border-radius: 30px;
  background: #00aeff;
  font-size: 20px;
}

button:active {
  background: black;
  color: white;
}

.delayed {
  transition: all 0.2s;
  transition-delay: 300ms;
}

.delayed:active {
  transition: none;
}

<h1>Sticky styles for better touch screen buttons!</h1>

<button>Normal button</button>

<button class="delayed"><a href="https://www.google.com"/>Delayed style</a></button>

<p>The CSS :active psuedo style is displayed between the time when a user touches down (when finger contacts screen) on a element to the time when the touch up (when finger leaves the screen) occures.   With a typical touch-screen tap interaction, the time of which the :active psuedo style is displayed can be very small resulting in the :active state not showing or being missed by the user entirely.  This can cause issues with users not undertanding if their button presses have actually reigstered or not.</p>

<p>Having the the :active styling stick around for a few hundred more milliseconds after touch up would would improve user understanding when they have interacted with a button.</p>

$post_data = [
  "item" => [
    'item_type_id' => $item_type,
    'string_key' => $string_key,
    'string_value' => $string_value,
    'string_extra' => $string_extra,
    'is_public' => $public,
    'is_public_for_contacts' => $public_contacts
  ]
];

$post_data = json_encode(post_data);
$post_data = json_decode(post_data);
return $post_data;

If you want it outside of loop then use the below code.

<?php
$author_id = get_post_field ('post_author', $cause_id);
$display_name = get_the_author_meta( 'display_name' , $author_id ); 
echo $display_name;
?>

Finally I have found the solution by using the following code:

$('body').on('click', '#upload', function(e){
        e.preventDefault();
        var formData = new FormData($(this).parents('form')[0]);

        $.ajax({
            url: 'upload.php',
            type: 'POST',
            xhr: function() {
                var myXhr = $.ajaxSettings.xhr();
                return myXhr;
            },
            success: function (data) {
                alert("Data Uploaded: "+data);
            },
            data: formData,
            cache: false,
            contentType: false,
            processData: false
        });
        return false;
});

In psql that would be

\dx

See the manual for details: http://www.postgresql.org/docs/current/static/app-psql.html

Doing it in plain SQL it would be a select on pg_extension:

SELECT * 
FROM pg_extension

http://www.postgresql.org/docs/current/static/catalog-pg-extension.html

Here's my solution using TimeUnit.

UPDATE: I should point out that this is written in groovy, but Java is almost identical.

def remainingStr = ""

/* Days */
int days = MILLISECONDS.toDays(remainingTime) as int
remainingStr += (days == 1) ? '1 Day : ' : "${days} Days : "
remainingTime -= DAYS.toMillis(days)

/* Hours */
int hours = MILLISECONDS.toHours(remainingTime) as int
remainingStr += (hours == 1) ? '1 Hour : ' : "${hours} Hours : "
remainingTime -= HOURS.toMillis(hours)

/* Minutes */
int minutes = MILLISECONDS.toMinutes(remainingTime) as int
remainingStr += (minutes == 1) ? '1 Minute : ' : "${minutes} Minutes : "
remainingTime -= MINUTES.toMillis(minutes)

/* Seconds */
int seconds = MILLISECONDS.toSeconds(remainingTime) as int
remainingStr += (seconds == 1) ? '1 Second' : "${seconds} Seconds"

cat file2 >> file1

The >> operator appends the output to the named file or creates the named file if it does not exist.

cat file1 file2 > file3

This concatenates two or more files to one. You can have as many source files as you need. For example,

cat *.txt >> newfile.txt

Update 20130902
In the comments eumiro suggests "don't try cat file1 file2 > file1." The reason this might not result in the expected outcome is that the file receiving the redirect is prepared before the command to the left of the > is executed. In this case, first file1 is truncated to zero length and opened for output, then the cat command attempts to concatenate the now zero-length file plus the contents of file2 into file1. The result is that the original contents of file1 are lost and in its place is a copy of file2 which probably isn't what was expected.

Update 20160919
In the comments tpartee suggests linking to backing information/sources. For an authoritative reference, I direct the kind reader to the sh man page at linuxcommand.org which states:

Before a command is executed, its input and output may be redirected using a special notation interpreted by the shell.

While that does tell the reader what they need to know it is easy to miss if you aren't looking for it and parsing the statement word by word. The most important word here being 'before'. The redirection is completed (or fails) before the command is executed.

In the example case of cat file1 file2 > file1 the shell performs the redirection first so that the I/O handles are in place in the environment in which the command will be executed before it is executed.

A friendlier version in which the redirection precedence is covered at length can be found at Ian Allen's web site in the form of Linux courseware. His I/O Redirection Notes page has much to say on the topic, including the observation that redirection works even without a command. Passing this to the shell:

$ >out

...creates an empty file named out. The shell first sets up the I/O redirection, then looks for a command, finds none, and completes the operation.

This my solution for POST and GET.

About the Post method:

If the body is a JSON object, so it's important to deserialize it with JSON.stringify and possibly set the Content-Lenght header accordingly:

      var bodyString=JSON.stringify(body)
      var _headers = {
        'Content-Length': Buffer.byteLength(bodyString)
      };

before writing it to the request:

request.write( bodyString );

About both Get and Post methods:

The timeout can occur as a socket disconnect, so you must register its handler like:

request.on('socket', function (socket) {
        socket.setTimeout( self.timeout );
        socket.on('timeout', function() {
            request.abort();
            if(timeout) return timeout( new Error('request timed out') );
        });
    });

while the request handler is

       request.on('timeout', function () {
          // Timeout happend. Server received request, but not handled it
          // (i.e. doesn't send any response or it took to long).
          // You don't know what happend.
          // It will emit 'error' message as well (with ECONNRESET code).
          req.abort();
          if(timeout) return timeout( new Error('request timed out') );
        });

I strongly suggest to register both the handlers.

The response body is chunked, so you must concat chunks at the data handler:

      var body = '';
      response.on('data', function(d) {
          body += d;
      });

At the end the body will contain the whole response body:

      response.on('end', function() {
        try {
            var jsonResponse=JSON.parse(body);
            if(success) return success( jsonResponse );
        } catch(ex) { // bad json
          if(error) return error(ex.toString());
        }
      });

It is safe to wrap with a try...catchtheJSON.parse` since you cannot be sure that it is a well-formatted json actually and there is no way to be sure of it at the time you do the request.

Not only is there a way to do this, there is more than one way to do this (which I concede is not very Pythonic, but then SQL*Developer is written in Java ).

I have a procedure with this signature: get_maxsal_by_dept( dno number, maxsal out number).

I highlight it in the SQL*Developer Object Navigator, invoke the right-click menu and chose Run. (I could use ctrl+F11.) This spawns a pop-up window with a test harness. (Note: If the stored procedure lives in a package, you'll need to right-click the package, not the icon below the package containing the procedure's name; you will then select the sproc from the package's "Target" list when the test harness appears.) In this example, the test harness will display the following:

DECLARE
  DNO NUMBER;
  MAXSAL NUMBER;
BEGIN
  DNO := NULL;

  GET_MAXSAL_BY_DEPT(
    DNO => DNO,
    MAXSAL => MAXSAL
  );
  DBMS_OUTPUT.PUT_LINE('MAXSAL = ' || MAXSAL);
END;

I set the variable DNO to 50 and press okay. In the Running - Log pane (bottom right-hand corner unless you've closed/moved/hidden it) I can see the following output:

Connecting to the database apc.
MAXSAL = 4500
Process exited.
Disconnecting from the database apc. 

To be fair the runner is less friendly for functions which return a Ref Cursor, like this one: get_emps_by_dept (dno number) return sys_refcursor.

DECLARE
  DNO NUMBER;
  v_Return sys_refcursor;
BEGIN
  DNO := 50;

  v_Return := GET_EMPS_BY_DEPT(
    DNO => DNO
  );
  -- Modify the code to output the variable
  -- DBMS_OUTPUT.PUT_LINE('v_Return = ' || v_Return);
END;

However, at least it offers the chance to save any changes to file, so we can retain our investment in tweaking the harness...

DECLARE
  DNO NUMBER;
  v_Return sys_refcursor;
  v_rec emp%rowtype;
BEGIN
  DNO := 50;

  v_Return := GET_EMPS_BY_DEPT(
    DNO => DNO
  );

  loop
    fetch v_Return into v_rec;
    exit when v_Return%notfound;
    DBMS_OUTPUT.PUT_LINE('name = ' || v_rec.ename);
  end loop;
END;

The output from the same location:

Connecting to the database apc.
name = TRICHLER
name = VERREYNNE
name = FEUERSTEIN
name = PODER
Process exited.
Disconnecting from the database apc. 

Alternatively we can use the old SQLPLus commands in the SQLDeveloper worksheet:

var rc refcursor 
exec :rc := get_emps_by_dept(30) 
print rc

In that case the output appears in Script Output pane (default location is the tab to the right of the Results tab).

The very earliest versions of the IDE did not support much in the way of SQL*Plus. However, all of the above commands have been supported since 1.2.1. Refer to the matrix in the online documentation for more info.

"When I type just var rc refcursor; and select it and run it, I get this error (GUI):"

There is a feature - or a bug - in the way the worksheet interprets SQLPlus commands. It presumes SQLPlus commands are part of a script. So, if we enter a line of SQL*Plus, say var rc refcursor and click Execute Statement (or F9 ) the worksheet hurls ORA-900 because that is not an executable statement i.e. it's not SQL . What we need to do is click Run Script (or F5 ), even for a single line of SQL*Plus.

"I am so close ... please help."

You program is a procedure with a signature of five mandatory parameters. You are getting an error because you are calling it as a function, and with just the one parameter:

exec :rc := get_account(1)

What you need is something like the following. I have used the named notation for clarity.

var ret1 number
var tran_cnt number
var msg_cnt number
var rc refcursor

exec :tran_cnt := 0
exec :msg_cnt := 123

exec get_account (Vret_val => :ret1, 
                  Vtran_count => :tran_cnt, 
                  Vmessage_count => :msg_cnt, 
                  Vaccount_id   => 1,
                  rc1 => :rc )

print tran_count 
print rc

That is, you need a variable for each OUT or IN OUT parameter. IN parameters can be passed as literals. The first two EXEC statements assign values to a couple of the IN OUT parameters. The third EXEC calls the procedure. Procedures don't return a value (unlike functions) so we don't use an assignment syntax. Lastly this script displays the value of a couple of the variables mapped to OUT parameters.

You probably need to reference it from the Rowsrather than as a cell:

var cellValue = dt.Rows[i][j];

with opencv 4.0;

• add -DOPENCV_GENERATE_PKGCONFIG=ON to build arguments
• pkg-config --cflags --libs opencv4 instead of opencv

You can also install simplejson.

If you have pip (see https://pypi.python.org/pypi/pip) as your Python package manager you can install simplejson with:

 pip install simplejson

This is similar to the comment of installing with easy_install, but I prefer pip to easy_install as you can easily uninstall in pip with "pip uninstall package".

Edited: Fixed mistake in code that stopped it working if there were no YourModel entries in the db.

There's a lot of mention of how you should use an AutoField, and of course, where possible you should use that.

However there are legitimate reasons for implementing auto-incrementing fields yourself (such as if you need an id to start from 500 or increment by tens for whatever reason).

In your models.py

from django.db import models

def from_500():
    '''
    Returns the next default value for the `ones` field,
    starts from 500
    '''
    # Retrieve a list of `YourModel` instances, sort them by
    # the `ones` field and get the largest entry
    largest = YourModel.objects.all().order_by('ones').last()
    if not largest:
        # largest is `None` if `YourModel` has no instances
        # in which case we return the start value of 500
        return 500
    # If an instance of `YourModel` is returned, we get it's
    # `ones` attribute and increment it by 1
    return largest.ones + 1

def add_ten():
    ''' Returns the next default value for the `tens` field'''
    # Retrieve a list of `YourModel` instances, sort them by
    # the `tens` field and get the largest entry
    largest = YourModel.objects.all().order_by('tens').last()
    if not largest:
        # largest is `None` if `YourModel` has no instances
        # in which case we return the start value of 10
        return 10
    # If an instance of `YourModel` is returned, we get it's
    # `tens` attribute and increment it by 10
    return largest.tens + 10


class YourModel(model.Model):
    ones = models.IntegerField(primary_key=True,
                               default=from_500)
    tens = models.IntegerField(default=add_ten)

Given that what you want is to determine the full id of the element based upon just the prefix, you're going to have to do a search of the entire DOM (or at least, a search of an entire subtree if you know of some element that is always guaranteed to contain your target element). You can do this with something like:

function findChildWithIdLike(node, prefix) {
    if (node && node.id && node.id.indexOf(prefix) == 0) {
        //match found
        return node;
    }

    //no match, check child nodes
    for (var index = 0; index < node.childNodes.length; index++) {
        var child = node.childNodes[index];
        var childResult = findChildWithIdLike(child, prefix);
        if (childResult) {
            return childResult;
        }
    }
};

Here is an example: http://jsfiddle.net/xwqKh/

Be aware that dynamic element ids like the ones you are working with are typically used to guarantee uniqueness of element ids on a single page. Meaning that it is likely that there are multiple elements that share the same prefix. Probably you want to find them all.

If you want to find all of the elements that have a given prefix, instead of just the first one, you can use something like what is demonstrated here: http://jsfiddle.net/xwqKh/1/

simple way to prevent the whole app from getting effected by system font size is to updateConfiguration using a base activity.

//in base activity add this code.
public  void adjustFontScale( Configuration configuration) {

    configuration.fontScale = (float) 1.0;
    DisplayMetrics metrics = getResources().getDisplayMetrics();
    WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
    wm.getDefaultDisplay().getMetrics(metrics);
    metrics.scaledDensity = configuration.fontScale * metrics.density;
    getBaseContext().getResources().updateConfiguration(configuration, metrics);

}

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    adjustFontScale( getResources().getConfiguration());
}

If you are on Windows, you can use the CreateThreadpoolTimer function to schedule a callback without needing to worry about thread management and without blocking the current thread.

template<typename T>
static void __stdcall timer_fired(PTP_CALLBACK_INSTANCE, PVOID context, PTP_TIMER timer)
{
    CloseThreadpoolTimer(timer);
    std::unique_ptr<T> callable(reinterpret_cast<T*>(context));
    (*callable)();
}

template <typename T>
void call_after(T callable, long long delayInMs)
{
    auto state = std::make_unique<T>(std::move(callable));
    auto timer = CreateThreadpoolTimer(timer_fired<T>, state.get(), nullptr);
    if (!timer)
    {
        throw std::runtime_error("Timer");
    }

    ULARGE_INTEGER due;
    due.QuadPart = static_cast<ULONGLONG>(-(delayInMs * 10000LL));

    FILETIME ft;
    ft.dwHighDateTime = due.HighPart;
    ft.dwLowDateTime = due.LowPart;

    SetThreadpoolTimer(timer, &ft, 0 /*msPeriod*/, 0 /*msWindowLength*/);
    state.release();
}

int main()
{
    auto callback = []
    {
        std::cout << "in callback\n";
    };

    call_after(callback, 1000);
    std::cin.get();
}

Jenkins has a link to their REST API in the bottom right of each page. This link appears on every page of Jenkins and points you to an API output for the exact page you are browsing. That should provide some understanding into how to build the API URls.

You can additionally use some wrapper, like I do, in Python, using http://jenkinsapi.readthedocs.io/en/latest/

Here is their website: https://wiki.jenkins-ci.org/display/JENKINS/Remote+access+API

TimeSpan span = end-start;
double totalMinutes = span.TotalMinutes;

I think there is MID() and maybe LEFT() and RIGHT() in Access.

I preferred search last blank cell:

Il you want last empty cell of column you can do that

Dim sh as Worksheet, r as range
set sh = ActiveWorksheet 'if you want an other it's possible

'find a value 
'Columns("A:D") 'to check on multiple columns 
Set r = sh.Columns("A").Find(What:="*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious)
'no value return first row
If r Is Nothing Then Set r = sh.Cells(1, "A") Else Set r = sh1.Cells(r.Row + 1, "A")

If this is to insert new row, find on multiple columns is a good choice because first column can contains less rows than next columns

Since PHP 5.4 you can use:

htmlspecialchars($string, ENT_XML1);

You should specify the encoding, such as:

htmlspecialchars($string, ENT_XML1, 'UTF-8');

Update

Note that the above will only convert:

• & to &
• < to <
• > to >

If you want to escape text for use in an attribute enclosed in double quotes:

htmlspecialchars($string, ENT_XML1 | ENT_COMPAT, 'UTF-8');

will convert " to " in addition to &, < and >.

And if your attributes are enclosed in single quotes:

htmlspecialchars($string, ENT_XML1 | ENT_QUOTES, 'UTF-8');

will convert ' to ' in addition to &, <, > and ".

(Of course you can use this even outside of attributes).

See the manual entry for htmlspecialchars.

You could try:

import pyodbc
# Using a DSN
cnxn = pyodbc.connect('DSN=odbc_datasource_name;UID=db_user_id;PWD=db_password')

Note: You will need to know the "odbc_datasource_name". In Windows you can search for ODBC Data Sources. The name will look something like this:

Data Source Name Example

It is worth noting that the accepted answer will round small floats down to zero.

>>> import numpy as np 
>>> arr = np.asarray([2.92290007e+00, -1.57376965e-03, 4.82011728e-08, 1.92896977e-12])
>>> print(arr)
[ 2.92290007e+00 -1.57376965e-03  4.82011728e-08  1.92896977e-12]
>>> np.round(arr, 2)
array([ 2.92, -0.  ,  0.  ,  0.  ]) 

You can use set_printoptions and a custom formatter to fix this and get a more numpy-esque printout with fewer decimal places:

>>> np.set_printoptions(formatter={'float': "{0:0.2e}".format})
>>> print(arr)
[2.92e+00 -1.57e-03 4.82e-08 1.93e-12]  

This way, you get the full versatility of format and maintain the full precision of numpy's datatypes.

Also note that this only affects printing, not the actual precision of the stored values used for computation.

I know this is a very old question, but this worked for me:

UPDATE TABLE SET FIELD1 =
CASE 
WHEN FIELD1 = Condition1 THEN 'Result1'
WHEN FIELD1 = Condition2 THEN 'Result2'
WHEN FIELD1 = Condition3 THEN 'Result3'
END;

The command has to be entered in the directory of the repository. The error is complaining that your current directory isn't a git repo

1. Are you in the right directory? Does typing ls show the right files?
2. Have you initialized the repository yet? Typed git init? (git-init documentation)

Either of those would cause your error.

public static void WriteLog(string strLog)
    {
        StreamWriter log;
        FileStream fileStream = null;
        DirectoryInfo logDirInfo = null;
        FileInfo logFileInfo;

        string logFilePath = "C:\\Logs\\";
        logFilePath = logFilePath + "Log-" + System.DateTime.Today.ToString("MM-dd-yyyy") + "." + "txt";           
        logFileInfo = new FileInfo(logFilePath);
        logDirInfo = new DirectoryInfo(logFileInfo.DirectoryName);
        if (!logDirInfo.Exists) logDirInfo.Create();
        if (!logFileInfo.Exists)
        {
            fileStream = logFileInfo.Create();
        }
        else
        {
            fileStream = new FileStream(logFilePath, FileMode.Append);
        }
        log = new StreamWriter(fileStream);
        log.WriteLine(strLog);
        log.Close();
    }

You can pass all similar type values in the function while calling it. In the function definition put a array so that all the passed values can be collected in that array. e.g. .

static void demo (String ... stringArray) {
  your code goes here where read the array stringArray
}

Try this:

SELECT Count(Student_ID) as 'StudentCount' 
FROM CourseSemOne
where Student_ID=3 
Having Count(Student_ID) < 6 and Count(Student_ID) > 0;

You can use console.log() in Firebug or Chrome to get a good object view here, like this:

$.getJSON('my.json', function(data) {
  console.log(data);
});

If you just want to view the string, look at the Resource view in Chrome or the Net view in Firebug to see the actual string response from the server (no need to convert it...you received it this way).

If you want to take that string and break it down for easy viewing, there's an excellent tool here: http://json.parser.online.fr/

You may also used sed print and quit:

sed -n '10{p;q;}' file   # print line 10

You want to do:

git reset HEAD~

If you don't want the changes and blow everything away:

git reset --hard HEAD~

Indeed, it would be nice if git-add had a --mode flag

git 2.9.x/2.10 (Q3 2016) actually will allow that (thanks to Edward Thomson):

git add --chmod=+x -- afile
git commit -m"Executable!"

That makes the all process quicker, and works even if core.filemode is set to false.

See commit 4e55ed3 (31 May 2016) by Edward Thomson (ethomson).
Helped-by: Johannes Schindelin (dscho).
^{(Merged by Junio C Hamano -- gitster -- in commit c8b080a, 06 Jul 2016)}

add: add --chmod=+x / --chmod=-x options

The executable bit will not be detected (and therefore will not be set) for paths in a repository with core.filemode set to false, though the users may still wish to add files as executable for compatibility with other users who do have core.filemode functionality.
For example, Windows users adding shell scripts may wish to add them as executable for compatibility with users on non-Windows.

Although this can be done with a plumbing command (git update-index --add --chmod=+x foo), teaching the git-add command allows users to set a file executable with a command that they're already familiar with.

I would use:

if (Stream.of("a","b","c").anyMatch("a"::equals)) {
    //Code to execute
};

or:

Stream.of("a","b","c")
    .filter("a"::equals)
    .findAny()
    .ifPresent(ignore -> /*Code to execute*/);

There is no OOTB feature at this moment which allows this. One way to achieve that could be to write a custom InputFormat and/or SerDe that will do this for you. You might this JIRA useful : https://issues.apache.org/jira/browse/HIVE-3751. (not related directly to your problem though).

Peeskillet's lame tutorial for working with JTables in Netbeans GUI Builder

• Set the table column headers
  1. Highglight the table in the design view then go to properties pane on the very right. Should be a tab that says "Properties". Make sure to highlight the table and not the scroll pane surrounding it, or the next step wont work
  2. Click on the ... button to the right of the property model. A dialog should appear.
  3. Set rows to 0, set the number of columns you want, and their names.

• Add a button to the frame somwhere,. This button will be clicked when the user is ready to submit a row

  1. Right-click on the button and select Events -> Action -> actionPerformed

  2. You should see code like the following auto-generated

     private void jButton1ActionPerformed(java.awt.event.ActionEvent) {}
     

• The jTable1 will have a DefaultTableModel. You can add rows to the model with your data

  private void jButton1ActionPerformed(java.awt.event.ActionEvent) {
      String data1 = something1.getSomething();
      String data2 = something2.getSomething();
      String data3 = something3.getSomething();
      String data4 = something4.getSomething();
  
      Object[] row = { data1, data2, data3, data4 };
  
      DefaultTableModel model = (DefaultTableModel) jTable1.getModel();
  
      model.addRow(row);
  
      // clear the entries.
  }
  

So for every set of data like from a couple text fields, a combo box, and a check box, you can gather that data each time the button is pressed and add it as a row to the model.

The following code will compare each item with other list of items using contains() method.Length of for loop must be bigger size() of bigger list then only it will compare all the values of both list.

List<String> str = new ArrayList<String>();
str.add("first");
str.add("second");
str.add("third");
List<String> str1 = new ArrayList<String>();
str1.add("first");
str1.add("second");
str1.add("third1");
for (int i = 0; i<str1.size(); i++)
{
System.out.println(str.contains(str1.get(i)));
}

Output is true true false

You will have to change some of your data types but the basics of what you just posted could be converted to something similar to this given the data types I used may not be accurate.

Dim DateToday As String: DateToday = Format(Date, "yyyy/MM/dd")
Dim Computers As New Collection
Dim disabledList As New Collection
Dim compArray(1 To 1) As String

'Assign data to first item in array
compArray(1) = "asdf"

'Format = Item, Key
Computers.Add "ErrorState", "Computer Name"

'Prints "ErrorState"
Debug.Print Computers("Computer Name")

Collections cannot be sorted so if you need to sort data you will probably want to use an array.

Moving everything over to VBA from VB.Net is not going to be simple since not all the data types are the same and you do not have the .Net framework. If you get stuck just post the code you're stuck converting and you will surely get some help!

Edit:

Sub ArrayExample()
    Dim subject As String
    Dim TestArray() As String
    Dim counter As Long

    subject = "Example"
    counter = Len(subject)

    ReDim TestArray(1 To counter) As String

    For counter = 1 To Len(subject)
        TestArray(counter) = Right(Left(subject, counter), 1)
    Next
End Sub

I know that the topic is old, but in case anyone still needs correct answer here what you need:

1. Override standard flow layout.

2. Add implementation like that:

   - (NSArray *) layoutAttributesForElementsInRect:(CGRect)rect {
       NSArray *answer = [super layoutAttributesForElementsInRect:rect];
   
       for(int i = 1; i < [answer count]; ++i) {
           UICollectionViewLayoutAttributes *currentLayoutAttributes = answer[i];
           UICollectionViewLayoutAttributes *prevLayoutAttributes = answer[i - 1];
           NSInteger maximumSpacing = 4;
           NSInteger origin = CGRectGetMaxX(prevLayoutAttributes.frame);
   
           if(origin + maximumSpacing + currentLayoutAttributes.frame.size.width < self.collectionViewContentSize.width) {
               CGRect frame = currentLayoutAttributes.frame;
               frame.origin.x = origin + maximumSpacing;
               currentLayoutAttributes.frame = frame;
           }
       }
       return answer;
   }
   

where maximumSpacing could be set to any value you prefer. This trick guarantees that the space between cells would be EXACTLY equal to maximumSpacing!!

Why I can't initialize static data members in class?

The C++ standard allows only static constant integral or enumeration types to be initialized inside the class. This is the reason a is allowed to be initialized while others are not.

Reference:
C++03 9.4.2 Static data members
§4

If a static data member is of const integral or const enumeration type, its declaration in the class definition can specify a constant-initializer which shall be an integral constant expression (5.19). In that case, the member can appear in integral constant expressions. The member shall still be defined in a namespace scope if it is used in the program and the namespace scope definition shall not contain an initializer.

What are integral types?

C++03 3.9.1 Fundamental types
§7

Types bool, char, wchar_t, and the signed and unsigned integer types are collectively called integral types.43) A synonym for integral type is integer type.

Footnote:

⁴³⁾ Therefore, enumerations (7.2) are not integral; however, enumerations can be promoted to int, unsigned int, long, or unsigned long, as specified in 4.5.

Workaround:

You could use the enum trick to initialize an array inside your class definition.

class A 
{
    static const int a = 3;
    enum { arrsize = 2 };

    static const int c[arrsize] = { 1, 2 };

};

Why does the Standard does not allow this?

Bjarne explains this aptly here:

A class is typically declared in a header file and a header file is typically included into many translation units. However, to avoid complicated linker rules, C++ requires that every object has a unique definition. That rule would be broken if C++ allowed in-class definition of entities that needed to be stored in memory as objects.

Why are only static const integral types & enums allowed In-class Initialization?

The answer is hidden in Bjarne's quote read it closely,
"C++ requires that every object has a unique definition. That rule would be broken if C++ allowed in-class definition of entities that needed to be stored in memory as objects."

Note that only static const integers can be treated as compile time constants. The compiler knows that the integer value will not change anytime and hence it can apply its own magic and apply optimizations, the compiler simply inlines such class members i.e, they are not stored in memory anymore, As the need of being stored in memory is removed, it gives such variables the exception to rule mentioned by Bjarne.

It is noteworthy to note here that even if static const integral values can have In-Class Initialization, taking address of such variables is not allowed. One can take the address of a static member if (and only if) it has an out-of-class definition.This further validates the reasoning above.

enums are allowed this because values of an enumerated type can be used where ints are expected.^{see citation above}

How does this change in C++11?

C++11 relaxes the restriction to certain extent.

C++11 9.4.2 Static data members
§3

If a static data member is of const literal type, its declaration in the class definition can specify a brace-or-equal-initializer in which every initializer-clause that is an assignment-expression is a constant expression. A static data member of literal type can be declared in the class definition with the constexpr specifier; if so, its declaration shall specify a brace-or-equal-initializer in which every initializer-clause that is an assignment-expression is a constant expression. [ Note: In both these cases, the member may appear in constant expressions. —end note ] The member shall still be defined in a namespace scope if it is used in the program and the namespace scope definition shall not contain an initializer.

Also, C++11 will allow(§12.6.2.8) a non-static data member to be initialized where it is declared(in its class). This will mean much easy user semantics.

Note that these features have not yet been implemented in latest gcc 4.7, So you might still get compilation errors.

An API is the interface through which you access someone elses code or through which someone else's code accesses yours. In effect the public methods and properties.

In order to use word-wrap: break-word, you need to set a width (in px). For example:

div {
    width: 250px;
    word-wrap: break-word;
}

word-wrap is a CSS3 property, but it should work in all browsers, including IE 5.5-9.

Enter the submodule directory:

cd projB/projA

Pull the repo from you project A (will not update the git status of your parent, project B):

git pull origin master

Go back to the root directory & check update:

cd ..
git status

If the submodule updated before, it will show something like below:

# Not currently on any branch.
# Changed but not updated:
#   (use "git add ..." to update what will be committed)
#   (use "git checkout -- ..." to discard changes in working directory)
#
#       modified:   projB/projA (new commits)
#

Then, commit the update:

git add projB/projA
git commit -m "projA submodule updated"

UPDATE

As @paul pointed out, since git 1.8, we can use

git submodule update --remote --merge

to update the submodule to the latest remote commit. It'll be convenient in most cases.

(Update: a few years later Google and Qwant "airlines" still send me here when searching for "git non-default ssh port") A probably better way in newer git versions is to use the GIT_SSH_COMMAND ENV.VAR like:

GIT_SSH_COMMAND="ssh -oPort=1234 -i ~/.ssh/myPrivate_rsa.key" \ git clone myuser@myGitRemoteServer:/my/remote/git_repo/path

This has the added advantage of allowing any other ssh suitable option (port, priv.key, IPv6, PKCS#11 device, ...).

This can be scripted in PL/SQL pretty simply based on the DBA/ALL/USER_CONSTRAINTS system view, but various details make not as trivial as it sounds. You have to be careful about the order in which it is done and you also have to take account of the presence of unique indexes.

The order is important because you cannot drop a unique or primary key that is referenced by a foreign key, and there could be foreign keys on tables in other schemas that reference primary keys in your own, so unless you have ALTER ANY TABLE privilege then you cannot drop those PKs and UKs. Also you cannot switch a unique index to being a non-unique index so you have to drop it in order to drop the constraint (for this reason it's almost always better to implement unique constraints as a "real" constraint that is supported by a non-unique index).

My version of a ping function:

• Works on Python 3.5 and later, on Windows and Linux (should work on Mac, but can't test it).
• On Windows, returns False if the ping command fails with "Destination Host Unreachable".
• And does not show any output, either as a pop-up window or in command line.

import platform, subprocess

def ping(host_or_ip, packets=1, timeout=1000):
    ''' Calls system "ping" command, returns True if ping succeeds.
    Required parameter: host_or_ip (str, address of host to ping)
    Optional parameters: packets (int, number of retries), timeout (int, ms to wait for response)
    Does not show any output, either as popup window or in command line.
    Python 3.5+, Windows and Linux compatible (Mac not tested, should work)
    '''
    # The ping command is the same for Windows and Linux, except for the "number of packets" flag.
    if platform.system().lower() == 'windows':
        command = ['ping', '-n', str(packets), '-w', str(timeout), host_or_ip]
        # run parameters: capture output, discard error messages, do not show window
        result = subprocess.run(command, stdin=subprocess.DEVNULL, stdout=subprocess.PIPE, stderr=subprocess.DEVNULL, creationflags=0x08000000)
        # 0x0800000 is a windows-only Popen flag to specify that a new process will not create a window.
        # On Python 3.7+, you can use a subprocess constant:
        #   result = subprocess.run(command, capture_output=True, creationflags=subprocess.CREATE_NO_WINDOW)
        # On windows 7+, ping returns 0 (ok) when host is not reachable; to be sure host is responding,

Extend WebViewClient and call onPageFinished() as follows:

mWebView.setWebViewClient(new WebViewClient() {

   public void onPageFinished(WebView view, String url) {
        // do your stuff here
    }
});

Two-way binding just means that:

1. When properties in the model get updated, so does the UI.
2. When UI elements get updated, the changes get propagated back to the model.

Backbone doesn't have a "baked-in" implementation of #2 (although you can certainly do it using event listeners). Other frameworks like Knockout do wire up two-way binding automagically.

In Backbone, you can easily achieve #1 by binding a view's "render" method to its model's "change" event. To achieve #2, you need to also add a change listener to the input element, and call model.set in the handler.

Here's a Fiddle with two-way binding set up in Backbone.

Just some additions to previous answers. There are aliases defined for Get-Content, for example if you are used to UNIX you might like cat, and there are also type and gc. So instead of

Get-Content -Path <Path> -Wait -Tail 10

you can write

# Print whole file and wait for appended lines and print them
cat <Path> -Wait
# Print last 10 lines and wait for appended lines and print them
cat <Path> -Tail 10 -Wait

What do you think of this?

if (isset($_SERVER['HTTPS']) && !empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off')

    $scheme = 'http';

The "no version information available" means that the library version number is lower on the shared object. For example, if your major.minor.patch number is 7.15.5 on the machine where you build the binary, and the major.minor.patch number is 7.12.1 on the installation machine, ld will print the warning.

You can fix this by compiling with a library (headers and shared objects) that matches the shared object version shipped with your target OS. E.g., if you are going to install to RedHat 3.4.6-9 you don't want to compile on Debian 4.1.1-21. This is one of the reasons that most distributions ship for specific linux distro numbers.

Otherwise, you can statically link. However, you don't want to do this with something like PAM, so you want to actually install a development environment that matches your client's production environment (or at least install and link against the correct library versions.)

Advice you get to rename the .so files (padding them with version numbers,) stems from a time when shared object libraries did not use versioned symbols. So don't expect that playing with the .so.n.n.n naming scheme is going to help (much - it might help if you system has been trashed.)

You last option will be compiling with a library with a different minor version number, using a custom linking script: http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/gnu-linker/scripts.html

To do this, you'll need to write a custom script, and you'll need a custom installer that runs ld against your client's shared objects, using the custom script. This requires that your client have gcc or ld on their production system.

Just to complete the answer, If you are using the LINQ syntax, you can just wrap it since it returns an IEnumerable:

(from int x in intList
 where x > 5
 select x * 2).FirstOrDefault()

"matt b" has it right, but to be specific, the "install" goal copies your built target to the local repository on your file system; useful for small changes across projects not currently meant for the full group.

The "deploy" goal uploads it to your shared repository for when your work is finished, and then can be shared by other people who require it for their project.

In your case, it seems that "install" is used to make the management of the deployment easier since CI's local repo is the shared repo. If CI was on another box, it would have to use the "deploy" goal.

You can try out my library CollectionsQuery. It allows to run LINQ like queries over collections of objects. You have to pass predicate, just like in LINQ. If you are using java6/7 than you have to use old syntax with Interfaces:

List<String> names = Queryable.from(people)
                                    .filter(new Predicate<Person>() {
                                                public boolean filter(Person p) {
                                                    return p.age>20;
                                                }
                                            })
                                    .map   (new Converter<Person,String>() {
                                                public Integer convert(Person p) {
                                                    return p.name;
                                                }
                                            })
                                    .toList();

You can also use it in Java8, or in old java with RetroLambda and it's gradle plugin, then you will have new fancy syntax:

List<String> names = Queryable.from(people)
                                    .filter(p->p.age>20)
                                    .map   (p->p.name)
                                    .toList();

If you need to run DB queryes, than you can look on JINQ, as mentioned above, but it can't be back-ported by RetroLambda, doe to use of serialized lambdas.

If you want to use something similar to the JavaScript, you just need to convert to strings first:

Console.WriteLine(mon.ToString() + "." + da.ToString() + "." + yer.ToString());

But a (much) better way would be to use the format option:

Console.WriteLine("{0}.{1}.{2}", mon, da, yer);

Based on bryanmac's answer. I'm just saving all logs into one file and then reading it with tail. Simple, but effective way to do this.

forever -o common.log -e common.log index.js && tail -f common.log

You can find these method usefull in reading and writing data in android.

 public void saveData(View view) {
    String text = "This is the text in the file, this is the part of the issue of the name and also called the name od the college ";
    FileOutputStream fos = null;

        fos = openFileOutput("FILE_NAME", MODE_PRIVATE);
        fos.write(text.getBytes());
        Toast.makeText(this, "Data is saved "+ getFilesDir(), Toast.LENGTH_SHORT).show();
    } catch (FileNotFoundException e) {
        e.printStackTrace();

        if (fos!= null){
            try {
                fos.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }


}

public void logData(View view) {
    FileInputStream fis = null;

    try {
        fis = openFileInput("FILE_NAME");
        InputStreamReader isr = new InputStreamReader(fis);
        BufferedReader br = new BufferedReader(isr);
        StringBuilder sb=  new StringBuilder();
        String text;
        while((text = br.readLine()) != null){
            sb.append(text).append("\n");
            Log.e("TAG", text
            );
        }

    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }finally {
        if(fis != null){
            try {
                fis.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

}

You may use scanf for this purpose with a little trick. Actually, you should allow user input until user hits Enter (\n). This will consider every character, including space. Here is example:

int main()
{
  char string[100], c;
  int i;
  printf("Enter the string: ");
  scanf("%s", string);
  i = strlen(string);      // length of user input till first space
  do
  {
    scanf("%c", &c);
    string[i++] = c;       // reading characters after first space (including it)
  } while (c != '\n');     // until user hits Enter
  string[i - 1] = 0;       // string terminating
return 0;
}

How this works? When user inputs characters from standard input, they will be stored in string variable until first blank space. After that, rest of entry will remain in input stream, and wait for next scanf. Next, we have a for loop that takes char by char from input stream (till \n) and apends them to end of string variable, thus forming a complete string same as user input from keyboard.

Hope this will help someone!

There are now official instructions from joyent (primary nodejs backer). For Ubuntu:

sudo apt-get purge nodejs npm
curl -sL https://deb.nodesource.com/setup | sudo bash -
sudo apt-get install -y nodejs

For other unix distributions, osx and windows see the link. Note this will install both node and npm.

My preferred option is very fast, I sampled a tab-delimited data file with 13 columns, 23.1M rows, 2.0GB uncompressed.

# randomly sample select 5% of lines in file
# including header row, exclude blank lines, new seed

time \
awk 'BEGIN  {srand()} 
     !/^$/  { if (rand() <= .05 || FNR==1) print > "data-sample.txt"}' data.txt

# awk  tsv004  3.76s user 1.46s system 91% cpu 5.716 total

Maven repositories do provide simple way to download sources jar.

I will explain it using a demonstration for "spring-boot-actuator-autoconfigure".

1. Go to maven repository - https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-actuator-autoconfigure
2. The page lists various versions. Click-on to desired one, let's say, 2.1.6.RELEASE - https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-actuator-autoconfigure/2.1.6.RELEASE
3. The page have link "View All" next to "Files". Click it - https://repo1.maven.org/maven2/org/springframework/boot/spring-boot-actuator-autoconfigure/2.1.6.RELEASE/
4. The page lists various files including the one for sources - https://repo1.maven.org/maven2/org/springframework/boot/spring-boot-actuator-autoconfigure/2.1.6.RELEASE/spring-boot-actuator-autoconfigure-2.1.6.RELEASE-sources.jar

Otherwise, you can always "git clone" the repo from github, if its there and get the specific code.

As explained by others, you can use "mvn dependency:sources" command the get and generate sources jar for the dependency you are using.

Note: Some dependencies will not have sources.jar, as those contains no source code but a pom file. e.g. spring-boot-starter-actuator. As in this case:

Starter POMs are a set of convenient dependency descriptors that you can include in your application. You get a one-stop-shop for all the Spring and related technology that you need, without having to hunt through sample code and copy paste loads of dependency descriptors.

Reference: Intro to Spring Boot Starters

For me this worked in WPF

    private void Window_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.Key == Key.Enter)
        {
            RoutedEventArgs routedEventArgs = new RoutedEventArgs(ButtonBase.ClickEvent, Button_OK);
            Button_OK.RaiseEvent(routedEventArgs);
        }
    }

If you are using debug configuration for maven, use the command

clean install

And skip all the tests.

Edit:

Sorry i forgot about pluck() as many have commented : Easiest way is :

return DB::table('users')->where('username', $username)->pluck('groupName');

Which will directly return the only the first result for the requested row as a string.

Using the fluent query builder you will obtain an array anyway. I mean The Query Builder has no idea how many rows will come back from that query. Here is what you can do to do it a bit cleaner

$result = DB::table('users')->select('groupName')->where('username', $username)->first();

The first() tells the queryBuilder to return only one row so no array, so you can do :

return $result->groupName;

Hope it helps

You'll probably want to try textContent instead of innerHTML.

Given innerHTML will return DOM content as a String and not exclusively the "text" in the div. It's fine if you know that your div contains only text but not suitable if every use case. For those cases, you'll probably have to use textContent instead of innerHTML

For example, considering the following markup:

<div id="test">
  Some <span class="foo">sample</span> text.
</div>

You'll get the following result:

var node = document.getElementById('test'),

htmlContent = node.innerHTML,
// htmlContent = "Some <span class="foo">sample</span> text."

textContent = node.textContent;
// textContent = "Some sample text."

See MDN for more details:

• textContent
• innerHTML

In addition to the above configurations, I had to set deployment target to "Open Select Deployment Target Dialog", run once (choosing my device from the options listed), and from then on Android Studio was able to see my device even after changing the deployment setting back to "USB Device". My SWAG is that since Android Studio uses its own internal cache to find your device, it has to be initialized first.

When user click on the logout button then write the following code:

Intent intent = new Intent(this, LoginActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);

And also when after login if you call new activity do not use finish();

Set the CheckBox as focusable="false" in your XML layout. Otherwise it will steal click events from the list view.

Of course, if you do this, you need to manually handle marking the CheckBox as checked/unchecked if the list item is clicked instead of the CheckBox, but you probably want that anyway.

You can simplify this with linq:

var item = ChunkList.SingleOrDefault(x => x.UniqueId == ChunkID);
if (item != null)
    ChunkList.Remove(item);

You can also do the following, which will also work if there is more than one match:

ChunkList.RemoveAll(x => x.UniqueId == ChunkID);

Here is a slightly different answer. Your column names & lengths may all match, but perhaps you are specifying the columns in the wrong order in your SELECT statement. Say tableX and tableY have columns with the same name, but in different order

 $('input[type="radio"]').change(function(){
      if($("input[name='group']:checked")){
      $(div).show();
    }
  });

i know its a little late but i think all these answers do have some problems while i did it like below and that works perfect.

create a activity life cycle callback like this:

 class ActivityLifeCycle implements ActivityLifecycleCallbacks{

    @Override
    public void onActivityCreated(Activity activity, Bundle savedInstanceState) {

    }

    @Override
    public void onActivityStarted(Activity activity) {

    }

    Activity lastActivity;
    @Override
    public void onActivityResumed(Activity activity) {
        //if (null == lastActivity || (activity != null && activity == lastActivity)) //use this condition instead if you want to be informed also when  app has been killed or started for the first time
        if (activity != null && activity == lastActivity) 
        {
            Toast.makeText(MyApp.this, "NOW!", Toast.LENGTH_LONG).show();
        }

        lastActivity = activity;
    }

    @Override
    public void onActivityPaused(Activity activity) {

    }

    @Override
    public void onActivityStopped(Activity activity) {

    }

    @Override
    public void onActivitySaveInstanceState(Activity activity, Bundle outState) {

    }

    @Override
    public void onActivityDestroyed(Activity activity) {

    }
}

and just register it on your application class like below:

public class MyApp extends Application {

@Override
public void onCreate() {
    super.onCreate();
    registerActivityLifecycleCallbacks(new ActivityLifeCycle());
}

This is what you are looking for. A complete TTS solution for the Mac. You can use this standalone or as a co-location Mac server for web apps:

http://wolfpaulus.com/jounal/mac/ttsserver/

An alternative way if you need something more (besides using the keys method):

hash = {"apple" => "fruit", "carrot" => "vegetable"}
array = hash.collect {|key,value| key }

obviously you would only do that if you want to manipulate the array while retrieving it..

Axios

An example (axios_example.js) using Axios in Node.js:

const axios = require('axios');
const express = require('express');
const app = express();
const port = process.env.PORT || 5000;

app.get('/search', function(req, res) {
    let query = req.query.queryStr;
    let url = `https://your.service.org?query=${query}`;

    axios({
        method:'get',
        url,
        auth: {
            username: 'the_username',
            password: 'the_password'
        }
    })
    .then(function (response) {
        res.send(JSON.stringify(response.data));
    })
    .catch(function (error) {
        console.log(error);
    });
});

var server = app.listen(port);

Be sure in your project directory you do:

npm init
npm install express
npm install axios
node axios_example.js

You can then test the Node.js REST API using your browser at: http://localhost:5000/search?queryStr=xxxxxxxxx

Similarly you can do post, such as:

axios({
  method: 'post',
  url: 'https://your.service.org/user/12345',
  data: {
    firstName: 'Fred',
    lastName: 'Flintstone'
  }
});

SuperAgent

Similarly you can use SuperAgent.

superagent.get('https://your.service.org?query=xxxx')
.end((err, response) => {
    if (err) { return console.log(err); }
    res.send(JSON.stringify(response.body));
});

And if you want to do basic authentication:

superagent.get('https://your.service.org?query=xxxx')
.auth('the_username', 'the_password')
.end((err, response) => {
    if (err) { return console.log(err); }
    res.send(JSON.stringify(response.body));
});

You need to call self.a() to invoke a from b. a is not a global function, it is a method on the class.

You may want to read through the Python tutorial on classes some more to get the finer details down.

You've probably miss-typed something above that bit of code or created your own class called IPAddress. If you're using the .net one, that function should be available.

Have you tried using System.Net.IPAddress just in case?

System.Net.IPAddress ipaddress = System.Net.IPAddress.Parse("127.0.0.1");  //127.0.0.1 as an example

The docs on Microsoft's site have a complete example which works fine on my machine.

Your code should work just as you expect it to if you add @classmethod decorators.

@classmethod 
def setup_class(cls):
    "Runs once per class"

@classmethod 
def teardown_class(cls):
    "Runs at end of class"

Write bytes and Create the file if not exists:

f = open('./put/your/path/here.png', 'wb')
f.write(data)
f.close()

wb means open the file in write binary mode.

If you are using PHP >= 7.2 consider using inbuilt sodium core extension for encrption.

It is modern and more secure. You can find more information here - http://php.net/manual/en/intro.sodium.php. and here - https://paragonie.com/book/pecl-libsodium/read/00-intro.md

Example PHP 7.2 sodium encryption class -

<?php

/**
 * Simple sodium crypto class for PHP >= 7.2
 * @author MRK
 */
class crypto {

    /**
     * 
     * @return type
     */
    static public function create_encryption_key() {
        return base64_encode(sodium_crypto_secretbox_keygen());
    }

    /**
     * Encrypt a message
     * 
     * @param string $message - message to encrypt
     * @param string $key - encryption key created using create_encryption_key()
     * @return string
     */
    static function encrypt($message, $key) {
        $key_decoded = base64_decode($key);
        $nonce = random_bytes(
                SODIUM_CRYPTO_SECRETBOX_NONCEBYTES
        );

        $cipher = base64_encode(
                $nonce .
                sodium_crypto_secretbox(
                        $message, $nonce, $key_decoded
                )
        );
        sodium_memzero($message);
        sodium_memzero($key_decoded);
        return $cipher;
    }

    /**
     * Decrypt a message
     * @param string $encrypted - message encrypted with safeEncrypt()
     * @param string $key - key used for encryption
     * @return string
     */
    static function decrypt($encrypted, $key) {
        $decoded = base64_decode($encrypted);
        $key_decoded = base64_decode($key);
        if ($decoded === false) {
            throw new Exception('Decryption error : the encoding failed');
        }
        if (mb_strlen($decoded, '8bit') < (SODIUM_CRYPTO_SECRETBOX_NONCEBYTES + SODIUM_CRYPTO_SECRETBOX_MACBYTES)) {
            throw new Exception('Decryption error : the message was truncated');
        }
        $nonce = mb_substr($decoded, 0, SODIUM_CRYPTO_SECRETBOX_NONCEBYTES, '8bit');
        $ciphertext = mb_substr($decoded, SODIUM_CRYPTO_SECRETBOX_NONCEBYTES, null, '8bit');

        $plain = sodium_crypto_secretbox_open(
                $ciphertext, $nonce, $key_decoded
        );
        if ($plain === false) {
            throw new Exception('Decryption error : the message was tampered with in transit');
        }
        sodium_memzero($ciphertext);
        sodium_memzero($key_decoded);
        return $plain;
    }

}

Sample Usage -

<?php 

$key = crypto::create_encryption_key();

$string = 'Sri Lanka is a beautiful country !';

echo $enc = crypto::encrypt($string, $key); 
echo crypto::decrypt($enc, $key);

Yup. :) You can use Hipify to convert CUDA code very easily to HIP code which can be compiled run on both AMD and nVidia hardware pretty good. Here are some links

GPUOpen very cool site by AMD that has tons of tools and software libraries to help with different aspects of GPU computing many of which work on both platforms

HIP Github Repository that shows the process to hipify

Java also does not use line numbers, which is a necessity for a GOTO function. Unlike C/C++, Java does not have goto statement, but java supports label. The only place where a label is useful in Java is right before nested loop statements. We can specify label name with break to break out a specific outer loop.

Late answer but I think this library will help a lot with caching images : https://github.com/crypticminds/ColdStorage.

Simply annotate the ImageView with @LoadCache(R.id.id_of_my_image_view, "URL_to_downlaod_image_from) and it will take care of downloading the image and loading it into the image view. You can also specify a placeholder image and loading animation.

Detailed documentation of the annotation is present here :- https://github.com/crypticminds/ColdStorage/wiki/@LoadImage-annotation

Pandas >= 0.25.0, named aggregations

Since pandas version 0.25.0 or higher, we are moving away from the dictionary based aggregation and renaming, and moving towards named aggregations which accepts a tuple. Now we can simultaneously aggregate + rename to a more informative column name:

Example:

df = pd.DataFrame(np.random.rand(4,4), columns=list('abcd'))
df['group'] = [0, 0, 1, 1]

          a         b         c         d  group
0  0.521279  0.914988  0.054057  0.125668      0
1  0.426058  0.828890  0.784093  0.446211      0
2  0.363136  0.843751  0.184967  0.467351      1
3  0.241012  0.470053  0.358018  0.525032      1

Apply GroupBy.agg with named aggregation:

df.groupby('group').agg(
             a_sum=('a', 'sum'),
             a_mean=('a', 'mean'),
             b_mean=('b', 'mean'),
             c_sum=('c', 'sum'),
             d_range=('d', lambda x: x.max() - x.min())
)

          a_sum    a_mean    b_mean     c_sum   d_range
group                                                  
0      0.947337  0.473668  0.871939  0.838150  0.320543
1      0.604149  0.302074  0.656902  0.542985  0.057681

Alternatively you could use a loop, keep the row number (counter should be the row number) and stop the loop when you find the first "ProjTemp".
Then it should look something like this:

Sub find()
    Dim i As Integer
    Dim firstTime As Integer
    Dim bNotFound As Boolean

    i = 1
    bNotFound = True

      Do While bNotFound
        If Cells(i, 2).Value = "ProjTemp" Then
            firstTime = i
            bNotFound = false
        End If
        i = i + 1
    Loop
End Sub

You can do this as follows:

for (Direction direction : EnumSet.allOf(Direction.class)) {
  // do stuff
}

TL;DR

A lot of effort to find a marginally more efficient solution. Difficult to justify the added complexity while sacrificing the simplicity of df.drop(dlst, 1, errors='ignore')

df.reindex_axis(np.setdiff1d(df.columns.values, dlst), 1)

Preamble
Deleting a column is semantically the same as selecting the other columns. I'll show a few additional methods to consider.

I'll also focus on the general solution of deleting multiple columns at once and allowing for the attempt to delete columns not present.

Using these solutions are general and will work for the simple case as well.

Setup
Consider the pd.DataFrame df and list to delete dlst

df = pd.DataFrame(dict(zip('ABCDEFGHIJ', range(1, 11))), range(3))
dlst = list('HIJKLM')

df

   A  B  C  D  E  F  G  H  I   J
0  1  2  3  4  5  6  7  8  9  10
1  1  2  3  4  5  6  7  8  9  10
2  1  2  3  4  5  6  7  8  9  10

dlst

['H', 'I', 'J', 'K', 'L', 'M']

The result should look like:

df.drop(dlst, 1, errors='ignore')

   A  B  C  D  E  F  G
0  1  2  3  4  5  6  7
1  1  2  3  4  5  6  7
2  1  2  3  4  5  6  7

Since I'm equating deleting a column to selecting the other columns, I'll break it into two types:

1. Label selection
2. Boolean selection

Label Selection

We start by manufacturing the list/array of labels that represent the columns we want to keep and without the columns we want to delete.

1. df.columns.difference(dlst)

   Index(['A', 'B', 'C', 'D', 'E', 'F', 'G'], dtype='object')
   

2. np.setdiff1d(df.columns.values, dlst)

   array(['A', 'B', 'C', 'D', 'E', 'F', 'G'], dtype=object)
   

3. df.columns.drop(dlst, errors='ignore')

   Index(['A', 'B', 'C', 'D', 'E', 'F', 'G'], dtype='object')
   

4. list(set(df.columns.values.tolist()).difference(dlst))

   # does not preserve order
   ['E', 'D', 'B', 'F', 'G', 'A', 'C']
   

5. [x for x in df.columns.values.tolist() if x not in dlst]

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

   ---

Columns from Labels
For the sake of comparing the selection process, assume:

 cols = [x for x in df.columns.values.tolist() if x not in dlst]

Then we can evaluate

1. df.loc[:, cols]
2. df[cols]
3. df.reindex(columns=cols)
4. df.reindex_axis(cols, 1)

Which all evaluate to:

   A  B  C  D  E  F  G
0  1  2  3  4  5  6  7
1  1  2  3  4  5  6  7
2  1  2  3  4  5  6  7

Boolean Slice

We can construct an array/list of booleans for slicing

1. ~df.columns.isin(dlst)
2. ~np.in1d(df.columns.values, dlst)
3. [x not in dlst for x in df.columns.values.tolist()]
4. (df.columns.values[:, None] != dlst).all(1)

Columns from Boolean
For the sake of comparison

bools = [x not in dlst for x in df.columns.values.tolist()]

1. df.loc[: bools]

Which all evaluate to:

   A  B  C  D  E  F  G
0  1  2  3  4  5  6  7
1  1  2  3  4  5  6  7
2  1  2  3  4  5  6  7

Robust Timing

Functions

setdiff1d = lambda df, dlst: np.setdiff1d(df.columns.values, dlst)
difference = lambda df, dlst: df.columns.difference(dlst)
columndrop = lambda df, dlst: df.columns.drop(dlst, errors='ignore')
setdifflst = lambda df, dlst: list(set(df.columns.values.tolist()).difference(dlst))
comprehension = lambda df, dlst: [x for x in df.columns.values.tolist() if x not in dlst]

loc = lambda df, cols: df.loc[:, cols]

comp = lambda df, dlst: [x not in dlst for x in df.columns.values.tolist()]
brod = lambda df, dlst: (df.columns.values[:, None] != dlst).all(1)

This is relative to the time it takes to run df.drop(dlst, 1, errors='ignore'). It seems like after all that effort, we only improve performance modestly.

If fact the best solutions use reindex or reindex_axis on the hack list(set(df.columns.values.tolist()).difference(dlst)). A close second and still very marginally better than drop is np.setdiff1d.

You can remove classes and add classes dynamically

$(document).ready(function(){
    $('#div').removeClass('left').addClass('right');
});

You can do it with the options

echo   $form->field($model, 'hidden1', 
      ['options' => ['value'=> 'your value'] ])->hiddenInput()->label(false);

You should learn about EAFP vs LBYL.

from sys import stdin, stdout
def main(infile=stdin, outfile=stdout):
    if isinstance(infile, basestring):
        infile=open(infile,'r')
    if isinstance(outfile, basestring):
        outfile=open(outfile,'w')
    for lineno, line in enumerate(infile, 1):
        line = line.strip()
         try:
             print >>outfile, int(line,16)
         except ValueError:
             return "Bad value at line %i: %r" % (lineno, line)

if __name__ == "__main__":
    from sys import argv, exit
    exit(main(*argv[1:]))

I do not think document fires the click event. Try using the body element to capture the click event. Might need to check on that...

You are trying to assign a value to a function, which is not possible in C. Try the comparison operator instead:

if (strcmp("hello", "hello") == 0)

As I'm using a laravel/php backend I tend to go with something like this:

/resource?filters[status_id]=1&filters[city]=Sydney&page=2&include=relatedResource

PHP automatically turns [] params into an array, so in this example I'll end up with a $filter variable that holds an array/object of filters, along with a page and any related resources I want eager loaded.

If you use another language, this might still be a good convention and you can create a parser to convert [] to an array.

To really fine-tune things, I recommend placing the appropriate selections in browser-targeting wrappers. This was the only thing that worked for me when I could not get IE7 and IE8 to "play nicely with others" (as I am currently working for a software company who continues to support them).

/* color or background image for all browsers, of course */            
#myBackground {
    background-color:#666; 
}
/* target chrome & safari without disrupting IE7-8 */
@media screen and (-webkit-min-device-pixel-ratio:0) {
    #myBackground {
        -khtml-opacity:.50; 
        opacity:.50;
    }
}
/* target firefox without disrupting IE */
@-moz-document url-prefix() {
    #myBackground {
        -moz-opacity:.50;
        opacity:0.5;
    }
}
/* and IE last so it doesn't blow up */
#myBackground {
    opacity:.50;
    filter:alpha(opacity=50);
    filter: progid:DXImageTransform.Microsoft.Alpha(opacity=0.5);
}

I may have redundancies in the above code -- if anyone wishes to clean it up further, feel free!

The question is rather vague. If you meant “how do I write a program so that a thread stops running when I want it to”, then various other responses should be helpful. But if you meant “I have an emergency with a server I cannot restart right now and I just need a particular thread to die, come what may”, then you need an intervention tool to match monitoring tools like jstack.

For this purpose I created jkillthread. See its instructions for usage.

With the modal open in the browser window, use the browser's console to try

$('#myModal').modal('hide');

If it works (and the modal closes) then you know that your close Javascript is not being sent from the server to the browser correctly.

If it doesn't work then you need to investigate further on the client what is happening. Eg make sure that there aren't two elements with the same id. Eg does it work the first time after page load but not the second time?

Browser's console: firebug for firefox, the debugging console for Chrome or Safari, etc.

This example pipes the complete contents of the repository to a file, which you can then quickly search for filenames within an editor:

svn list -R svn://svn > filelist.txt

This is useful if the repository is relatively static and you want to do rapid searches without having to repeatedly load everything from the SVN server.

You can use the following:

    /// <summary>
    /// Serializes an object.
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="serializableObject"></param>
    /// <param name="fileName"></param>
    public void SerializeObject<T>(T serializableObject, string fileName)
    {
        if (serializableObject == null) { return; }

        try
        {
            XmlDocument xmlDocument = new XmlDocument();
            XmlSerializer serializer = new XmlSerializer(serializableObject.GetType());
            using (MemoryStream stream = new MemoryStream())
            {
                serializer.Serialize(stream, serializableObject);
                stream.Position = 0;
                xmlDocument.Load(stream);
                xmlDocument.Save(fileName);
            }
        }
        catch (Exception ex)
        {
            //Log exception here
        }
    }


    /// <summary>
    /// Deserializes an xml file into an object list
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="fileName"></param>
    /// <returns></returns>
    public T DeSerializeObject<T>(string fileName)
    {
        if (string.IsNullOrEmpty(fileName)) { return default(T); }

        T objectOut = default(T);

        try
        {
            XmlDocument xmlDocument = new XmlDocument();
            xmlDocument.Load(fileName);
            string xmlString = xmlDocument.OuterXml;

            using (StringReader read = new StringReader(xmlString))
            {
                Type outType = typeof(T);

                XmlSerializer serializer = new XmlSerializer(outType);
                using (XmlReader reader = new XmlTextReader(read))
                {
                    objectOut = (T)serializer.Deserialize(reader);
                }
            }
        }
        catch (Exception ex)
        {
            //Log exception here
        }

        return objectOut;
    }

Select Window->Show View, if it is not shown there then select other. Under General you can see Project Explorer.

I had a similar issue, but I needed to be sure that the order of the ID is aligning to the order in the source file. My solution is using a VIEW for the BULK INSERT:

Keep your table as it is and create this VIEW (select everything except the ID column)

CREATE VIEW [dbo].[VW_Employee]
AS
SELECT [Name], [Address]
FROM [dbo].[Employee];

Your BULK INSERT should then look like:

BULK INSERT [dbo].[VW_Employee] FROM 'path\tempFile.csv ' 
WITH (FIRSTROW = 2,FIELDTERMINATOR = ',' , ROWTERMINATOR = '\n');

This code works for me:

Sub test()
    Dim myRange As Range
    Dim NumRows As Integer

    Set myRange = Range("A:A")
    NumRows = Application.WorksheetFunction.CountA(myRange)

    MsgBox NumRows
End Sub

git remote set-url {name} {url}

ex) git remote set-url origin https://github.com/myName/GitTest.git

For those who use this command and doesn't work or the file is not there and are using Ruby on Rails

rm /usr/local/var/postgres/postmaster.pid

Or any other command and just keep on failing.

I solved this problem uninstalling with Brew. I had to uninstall with brew 2 times, because at the first uninstall there will remain another version of postgresql, with the second uninstall the process will be completed.

Install postgresql with Brew

Then drop, create and migrate the data bases of the project

(Don't forget to start the postgresql server)

Python 3.6+ (2017)

In the recent versions of Python one would use f-strings (see also PEP498).

With f-strings one should use double {{ or }}

n = 42  
print(f" {{Hello}} {n} ")

produces the desired

 {Hello} 42

If you need to resolve an expression in the brackets instead of using literal text you'll need three sets of brackets:

hello = "HELLO"
print(f"{{{hello.lower()}}}")

produces

{hello}

Here is my solution using list comprehension to search for multiple file extensions recursively in a directory and all subdirectories:

import os, glob

def _globrec(path, *exts):
""" Glob recursively a directory and all subdirectories for multiple file extensions 
    Note: Glob is case-insensitive, i. e. for '\*.jpg' you will get files ending
    with .jpg and .JPG

    Parameters
    ----------
    path : str
        A directory name
    exts : tuple
        File extensions to glob for

    Returns
    -------
    files : list
        list of files matching extensions in exts in path and subfolders

    """
    dirs = [a[0] for a in os.walk(path)]
    f_filter = [d+e for d in dirs for e in exts]    
    return [f for files in [glob.iglob(files) for files in f_filter] for f in files]

my_pictures = _globrec(r'C:\Temp', '\*.jpg','\*.bmp','\*.png','\*.gif')
for f in my_pictures:
    print f

You can use Apache POI for creating native binary xls files.

Or you can use JExcelApi which is another, and somewhat light-weight as far as I can remember, Java library for Excel.

I needed to get the last id way after inserting it, so

$lastid = $wpdb->insert_id;

Was not an option.

Did the follow:

global $wpdb;
$id = $wpdb->get_var( 'SELECT id FROM ' . $wpdb->prefix . 'table' . ' ORDER BY id DESC LIMIT 1');

Here's another way to do it in VBA.

Function ConvertToArray(ByVal value As String)
    value = StrConv(value, vbUnicode)
    ConvertToArray = Split(Left(value, Len(value) - 1), vbNullChar)
End Function
Sub example()
    Dim originalString As String
    originalString = "hi there"
    Dim myArray() As String
    myArray = ConvertToArray(originalString)
End Sub

As some mentioned in the comments, you can put the images in the public folder. This is also explained in the docs of Create-React-App: https://create-react-app.dev/docs/using-the-public-folder/

I had the same problem with Firefox 30 + Selenium 2.49 + Ubuntu 15.04.

It worked fine with Ubuntu 14 but after upgrade to 15.04 I got same RANDR warning and problem at starting Firefox using Xfvb.

After adding +extension RANDR it worked again.

$ vim /etc/init/xvfb.conf

#!upstart
description "Xvfb Server as a daemon"

start on filesystem and started networking
stop on shutdown

respawn

env XVFB=/usr/bin/Xvfb
env XVFBARGS=":10 -screen 1 1024x768x24 -ac +extension GLX +extension RANDR +render -noreset"
env PIDFILE=/var/run/xvfb.pid

exec start-stop-daemon --start --quiet --make-pidfile --pidfile $PIDFILE --exec $XVFB -- $XVFBARGS >> /var/log/xvfb.log 2>&1

Your logic is correct but you have 2 mistakes apparently everyone missed:

just change if(Number(i) = 'NaN') to if(Number(i) == NaN)

NaN is a constant and you should use double equality signs to compare, a single one is used to assign values to variables.

Try getppid() if you want your C program to print your shell's PID.

For collapse, you can try CTRL + M + O and expand using CTRL + M + P. This works in VS2008.

Thanks to dimo414's answer, this shows how his great solution works, and shows that you can have quotes and variables in the text easily as well:

example output

$ ./test.sh

The text from the example function is:
  Welcome dev: Would you "like" to know how many 'files' there are in /tmp?

  There are "      38" files in /tmp, according to the "wc" command

test.sh

#!/bin/bash

function text1()
{
  COUNT=$(\ls /tmp | wc -l)
cat <<EOF

  $1 Would you "like" to know how many 'files' there are in /tmp?

  There are "$COUNT" files in /tmp, according to the "wc" command

EOF
}

function main()
{
  OUT=$(text1 "Welcome dev:")
  echo "The text from the example function is: $OUT"
}

main

Thanks All, I found how to do it, which is the same as Dave and Sergey:

I am using QT Creator:

In the main GUI window create using the drag drop GUI and create label (e.g. "myLabel")

In the callback of the button (clicked) do the following using the (*ui) pointer to the user interface window:

void MainWindow::on_pushButton_clicked()
{
     QImage imageObject;
     imageObject.load(imagePath);
     ui->myLabel->setPixmap(QPixmap::fromImage(imageObject));

     //OR use the other way by setting the Pixmap directly

     QPixmap pixmapObject(imagePath");
     ui->myLabel2->setPixmap(pixmapObject);
}

The difference between compile time and run time is an example of what pointy-headed theorists call the phase distinction. It is one of the hardest concepts to learn, especially for people without much background in programming languages. To approach this problem, I find it helpful to ask

1. What invariants does the program satisfy?
2. What can go wrong in this phase?
3. If the phase succeeds, what are the postconditions (what do we know)?
4. What are the inputs and outputs, if any?

Compile time

1. The program need not satisfy any invariants. In fact, it needn't be a well-formed program at all. You could feed this HTML to the compiler and watch it barf...
2. What can go wrong at compile time:
   • Syntax errors
   • Typechecking errors
   • (Rarely) compiler crashes
3. If the compiler succeeds, what do we know?
   • The program was well formed---a meaningful program in whatever language.
   • It's possible to start running the program. (The program might fail immediately, but at least we can try.)
4. What are the inputs and outputs?
   • Input was the program being compiled, plus any header files, interfaces, libraries, or other voodoo that it needed to import in order to get compiled.
   • Output is hopefully assembly code or relocatable object code or even an executable program. Or if something goes wrong, output is a bunch of error messages.

Run time

1. We know nothing about the program's invariants---they are whatever the programmer put in. Run-time invariants are rarely enforced by the compiler alone; it needs help from the programmer.

2. What can go wrong are run-time errors:

   • Division by zero
   • Dereferencing a null pointer
   • Running out of memory

   Also there can be errors that are detected by the program itself:

   • Trying to open a file that isn't there
   • Trying find a web page and discovering that an alleged URL is not well formed
3. If run-time succeeds, the program finishes (or keeps going) without crashing.
4. Inputs and outputs are entirely up to the programmer. Files, windows on the screen, network packets, jobs sent to the printer, you name it. If the program launches missiles, that's an output, and it happens only at run time :-)

readonly="true" is invalid HTML5, readonly="readonly" is valid.

HTML5 spec:

http://www.w3.org/TR/html5/forms.html#attr-input-readonly :

The readonly attribute is a boolean attribute

http://www.w3.org/TR/html5/infrastructure.html#boolean-attributes :

The presence of a boolean attribute on an element represents the true value, and the absence of the attribute represents the false value.

If the attribute is present, its value must either be the empty string or a value that is an ASCII case-insensitive match for the attribute's canonical name, with no leading or trailing whitespace.

Conclusion:

The following are valid, equivalent and true:

<input type="text" readonly />
<input type="text" readonly="" />
<input type="text" readonly="readonly" />
<input type="text" readonly="ReAdOnLy" />

The following are invalid:

<input type="text" readonly="0" />
<input type="text" readonly="1" />
<input type="text" readonly="false" />
<input type="text" readonly="true" />

The absence of the attribute is the only valid syntax for false:

<input type="text"/>

Recommendation

If you care about writing valid XHTML, use readonly="readonly", since <input readonly> is invalid and other alternatives are less readable. Else, just use <input readonly> as it is shorter.

it is very easy:

add \documentclass[oneside]{book} and youre fine ;)

For the postgrersql10

I have solved it with

yum install postgresql10-contrib

Don't forget to activate extensions in postgresql.conf

shared_preload_libraries = 'pg_stat_statements'
pg_stat_statements.track = all

then of course restart

systemctl restart postgresql-10.service 

all of the needed extensions you can find here

/usr/pgsql-10/share/extension/

Very simple way just put:

if [ "$(whoami)" == "root" ] ; then
    # you are root
else
    # you are not root
fi

The benefit of using this instead of id is that you can check whether a certain non-root user is running the command, too; eg.

if [ "$(whoami)" == "john" ] ; then
    # you are john
else
    # you are not john
fi

Old question but I had to address MrFox's comment in the accepted answer. Rotating an image when the size changes cuts off the edges of the image. One solution is to redraw the original on a larger image, centered, where the larger image's dimensions compensate for the need of not clipping the edges. For example, I wanted to be able to design a game's tiles at a normal angle but re-draw them at a 45-degree angle for an isometric view.

Here are example images (yellow borders are to make it easier to see here).

The original image:

The centered tile in a larger image:

The rotated image (where you rotate the larger image, not the original):

The code (based in part on this answer in another question):

private Bitmap RotateImage(Bitmap rotateMe, float angle)
{
    //First, re-center the image in a larger image that has a margin/frame
    //to compensate for the rotated image's increased size

    var bmp = new Bitmap(rotateMe.Width + (rotateMe.Width / 2), rotateMe.Height + (rotateMe.Height / 2));

    using (Graphics g = Graphics.FromImage(bmp))
        g.DrawImageUnscaled(rotateMe, (rotateMe.Width / 4), (rotateMe.Height / 4), bmp.Width, bmp.Height);

    bmp.Save("moved.png");
    rotateMe = bmp;

    //Now, actually rotate the image
    Bitmap rotatedImage = new Bitmap(rotateMe.Width, rotateMe.Height);

    using (Graphics g = Graphics.FromImage(rotatedImage))
    {
        g.TranslateTransform(rotateMe.Width / 2, rotateMe.Height / 2);   //set the rotation point as the center into the matrix
        g.RotateTransform(angle);                                        //rotate
        g.TranslateTransform(-rotateMe.Width / 2, -rotateMe.Height / 2); //restore rotation point into the matrix
        g.DrawImage(rotateMe, new Point(0, 0));                          //draw the image on the new bitmap
    }

    rotatedImage.Save("rotated.png");
    return rotatedImage;
}

You need to create an XmlReaderSettings instance and pass that to your XmlReader when you create it. Then you can subscribe to the ValidationEventHandler in the settings to receive validation errors. Your code will end up looking like this:

using System.Xml;
using System.Xml.Schema;
using System.IO;

public class ValidXSD
{
    public static void Main()
    {

        // Set the validation settings.
        XmlReaderSettings settings = new XmlReaderSettings();
        settings.ValidationType = ValidationType.Schema;
        settings.ValidationFlags |= XmlSchemaValidationFlags.ProcessInlineSchema;
        settings.ValidationFlags |= XmlSchemaValidationFlags.ProcessSchemaLocation;
        settings.ValidationFlags |= XmlSchemaValidationFlags.ReportValidationWarnings;
        settings.ValidationEventHandler += new ValidationEventHandler(ValidationCallBack);

        // Create the XmlReader object.
        XmlReader reader = XmlReader.Create("inlineSchema.xml", settings);

        // Parse the file. 
        while (reader.Read()) ;

    }

You can simply convert it in a comment..

Or you can do this:

br {
display: none;
}

But if you do not want it why are you puting that there?

you can use send instead of sendFile so you wont face with error! this works will help you!

fs.readFile('public/index1.html',(err,data)=>{
if(err){
  consol.log(err);
}else {
res.setHeader('Content-Type', 'application/pdf');

for telling browser that your response is type of PDF

res.setHeader('Content-Disposition', 'attachment; filename='your_file_name_for_client.pdf');

if you want that file open immediately on the same page after user download it.write 'inline' instead attachment in above code.

res.send(data)

Be careful when exporting from and importing to different MySQL versions as the mysql tables may have different columns. Grant privileges may fail to work if you're out of luck. I created this script (mysql_export_grants.sql ) to dump the grants for importing into the new database, just in case:

#!/bin/sh
stty -echo
printf 'Password: ' >&2
read PASSWORD
stty echo
printf "\n"
if [ -z "$PASSWORD" ]; then
        echo 'No password given!'
        exit 1
fi
MYSQL_CONN="-uroot -p$PASSWORD"
mysql ${MYSQL_CONN} --skip-column-names -A -e"SELECT CONCAT('SHOW GRANTS FOR ''',user,'''@''',host,''';') FROM mysql.user WHERE user<>''" | mysql ${MYSQL_CONN} --skip-column-names -A | sed 's/$/;/g'

const clone = (obj) => Object.assign({}, obj);

const renameKey = (object, key, newKey) => {

    const clonedObj = clone(object);
  
    const targetKey = clonedObj[key];
  
  
  
    delete clonedObj[key];
  
    clonedObj[newKey] = targetKey;
  
    return clonedObj;
     };

  let contact = {radiant: 11, dire: 22};





contact = renameKey(contact, 'radiant', 'aplha');

contact = renameKey(contact, 'dire', 'omega');



console.log(contact); // { aplha: 11, omega: 22 };

This problem occur due to wrong spell or undefined database name. Make sure your database name, table name and all column name is same as from phpmyadmin.

Thank You

Yes, you can use the File API for this.

Here's a complete example (see comments):

document.getElementById("btnLoad").addEventListener("click", function showFileSize() {
    // (Can't use `typeof FileReader === "function"` because apparently it
    // comes back as "object" on some browsers. So just see if it's there
    // at all.)
    if (!window.FileReader) { // This is VERY unlikely, browser support is near-universal
        console.log("The file API isn't supported on this browser yet.");
        return;
    }

    var input = document.getElementById('fileinput');
    if (!input.files) { // This is VERY unlikely, browser support is near-universal
        console.error("This browser doesn't seem to support the `files` property of file inputs.");
    } else if (!input.files[0]) {
        addPara("Please select a file before clicking 'Load'");
    } else {
        var file = input.files[0];
        addPara("File " + file.name + " is " + file.size + " bytes in size");
    }
});

function addPara(text) {
    var p = document.createElement("p");
    p.textContent = text;
    document.body.appendChild(p);
}

body {
    font-family: sans-serif;
}

<form action='#' onsubmit="return false;">
<input type='file' id='fileinput'>
<input type='button' id='btnLoad' value='Load'>
</form>

Slightly off-topic, but: Note that client-side validation is no substitute for server-side validation. Client-side validation is purely to make it possible to provide a nicer user experience. For instance, if you don't allow uploading a file more than 5MB, you could use client-side validation to check that the file the user has chosen isn't more than 5MB in size and give them a nice friendly message if it is (so they don't spend all that time uploading only to get the result thrown away at the server), but you must also enforce that limit at the server, as all client-side limits (and other validations) can be circumvented.

For the record, jQuery has an is() function for this:

a.is(b)

Note that a is already a jQuery instance.

Here's another alternative if, for any reason, you can't or don't want to use HttpUtility.ParseQueryString().

This is built to be somewhat tolerant to "malformed" query strings, i.e. http://test/test.html?empty= becomes a parameter with an empty value. The caller can verify the parameters if needed.

public static class UriHelper
{
    public static Dictionary<string, string> DecodeQueryParameters(this Uri uri)
    {
        if (uri == null)
            throw new ArgumentNullException("uri");

        if (uri.Query.Length == 0)
            return new Dictionary<string, string>();

        return uri.Query.TrimStart('?')
                        .Split(new[] { '&', ';' }, StringSplitOptions.RemoveEmptyEntries)
                        .Select(parameter => parameter.Split(new[] { '=' }, StringSplitOptions.RemoveEmptyEntries))
                        .GroupBy(parts => parts[0],
                                 parts => parts.Length > 2 ? string.Join("=", parts, 1, parts.Length - 1) : (parts.Length > 1 ? parts[1] : ""))
                        .ToDictionary(grouping => grouping.Key,
                                      grouping => string.Join(",", grouping));
    }
}

Make sure you have closed your MSAccess file before running the java program.

The second is pretty standard. You often prefer to return a reference from an assignment operator so that statements like a = b = c; resolve as expected. I can't think of any cases where I would want to return a copy from assignment.

One thing to note is that if you aren't needing a deep copy it's sometimes considered best to use the implicit copy constructor and assignment operator generated by the compiler than roll your own. Really up to you though ...

Edit:

Here's some basic calls:

SimpleCircle x; // default constructor
SimpleCircle y(x); // copy constructor
x = y; // assignment operator

Now say we had the first version of your assignment operator:

SimpleCircle SimpleCircle::operator=(const SimpleCircle & rhs)
{
     if(this == &rhs)
        return *this; // calls copy constructor SimpleCircle(*this)
     itsRadius = rhs.getRadius(); // copy member
     return *this; // calls copy constructor
}

It calls the copy constructor and passes a reference to this in order to construct the copy to be returned. Now in the second example we avoid the copy by just returning a reference to this

SimpleCircle & SimpleCircle::operator=(const SimpleCircle & rhs)
{
    if(this == &rhs)
       return *this; // return reference to this (no copy)
    itsRadius = rhs.getRadius(); // copy member
    return *this; // return reference to this (no copy)
}

If I understand you correctly, you have a utf-8 encoded byte-string in your code.

Converting a byte-string to a unicode string is known as decoding (unicode -> byte-string is encoding).

You do that by using the unicode function or the decode method. Either:

unicodestr = unicode(bytestr, encoding)
unicodestr = unicode(bytestr, "utf-8")

Or:

unicodestr = bytestr.decode(encoding)
unicodestr = bytestr.decode("utf-8")

No, according to Apple here:

Note: You cannot install apps from the App Store in simulation environments.

To check if o is an instance of str or any subclass of str, use isinstance (this would be the "canonical" way):

if isinstance(o, str):

To check if the type of o is exactly str (exclude subclasses):

if type(o) is str:

The following also works, and can be useful in some cases:

if issubclass(type(o), str):

See Built-in Functions in the Python Library Reference for relevant information.

One more note: in this case, if you're using Python 2, you may actually want to use:

if isinstance(o, basestring):

because this will also catch Unicode strings (unicode is not a subclass of str; both str and unicode are subclasses of basestring). Note that basestring no longer exists in Python 3, where there's a strict separation of strings (str) and binary data (bytes).

Alternatively, isinstance accepts a tuple of classes. This will return True if o is an instance of any subclass of any of (str, unicode):

if isinstance(o, (str, unicode)):

Did you remember setting the height of the html and body tags in your CSS? This is generally how I've gotten DIVs to extend to full height:

<html>
  <head>
    <style type="text/css">

      html,body { height: 100%; margin: 0px; padding: 0px; }
      #full { background: #0f0; height: 100% }

    </style>
  </head>
  <body>
    <div id="full">
    </div>
  </body>
</html>

The relevant part of the error message is

...when a column list is used...

You are not using a column list, you are using SELECT *. Use a column list instead:

SET IDENTITY_INSERT [MyDB].[dbo].[Equipment] ON 

INSERT INTO [MyDB].[dbo].[Equipment] (Col1, Col2, ...)
SELECT Col1, Col2, ... FROM [MyDBQA].[dbo].[Equipment] 

SET IDENTITY_INSERT [MyDB].[dbo].[Equipment] OFF 

for some reason I couldn't get it to work with the outer join.

So I used:

SELECT * from t1 where not Id in (SELECT DISTINCT t2.id from t2)

Just drop the option v.

-v is for verbose. If you don't use it then it won't display:

tar -zxf tmp.tar.gz -C ~/tmp1

For me the filename involved was appended with a querystring, which this function didn't like.

$path = 'path/to/my/file.js?v=2'

Solution was to chop that off first:

$path = preg_replace('/\?v=[\d]+$/', '', $path);
$fileTime = filemtime($path);

SELECT product FROM Your_table_name WHERE Product LIKE '%XYZ%';

The above statement will show result from a single table. If you want to add more tables then simply use the UNION statement.

SELECT product FROM Table_name_1 
WHERE Product LIKE '%XYZ%'  
UNION  
SELECT product FROM Table_name_2 
WHERE Product LIKE '%XYZ%'  
UNION  
SELECT product FROM Table_name_3 
WHERE Product LIKE '%XYZ%' 

... and so on

An empty border is transparent. You need to specify a Line Border or some other visible border when you set the border in order to see it.

Based on Edit to question:

The painting does not honor the border. Add this line of code to your test and you will see the border:

    jboard.setBorder(BorderFactory.createEmptyBorder(0,10,10,10)); 
    jboard.add(new JButton("Test"));  //Add this line
    frame.add(jboard);

I think onRestart() works better for this.

@Override
public void onRestart() { 
    super.onRestart();
    //When BACK BUTTON is pressed, the activity on the stack is restarted
    //Do what you want on the refresh procedure here
}

You could code what you want to do when the Activity is restarted (called again from the event 'back button pressed') inside onRestart().

For example, if you want to do the same thing you do in onCreate(), paste the code in onRestart() (eg. reconstructing the UI with the updated values).

A static method can be called without an instance of the class. In your example you can call foo.bar2(), but not foo.bar(), because for bar you need an instance. Following code would work:

foo var = new ImplementsFoo();
var.bar();

If you call a static method, it will be executed always the same code. In the above example, even if you redefine bar2 in ImplementsFoo, a call to var.bar2() would execute foo.bar2().

If bar2 now has no implementation (that's what abstract means), you can call a method without implementation. That's very harmful.
