QString data;
   data.toStdString().c_str();

could even throw exception on VS2017 compiler in xstring

 ~basic_string() _NOEXCEPT
        {   // destroy the string
        _Tidy_deallocate();
        }

the right way ( secure - no exception) is how is explained above from Artyom

 QString qs;

    // Either this if you use UTF-8 anywhere
    std::string utf8_text = qs.toUtf8().constData();

    // or this if you're on Windows :-)
    std::string current_locale_text = qs.toLocal8Bit().constData();

If compiled with STL compatibility, QString has a static method to convert a std::string to a QString:

std::string str = "abc";
QString qstr = QString::fromStdString(str);

Use the left function:

QString yourString = "This is a string";
QString leftSide = yourString.left(5);
qDebug() << leftSide; // output "This "

Also have a look at mid() if you want more control.

If your string contains non-ASCII characters - it's better to do it this way: s.toUtf8().data() (or s->toUtf8().data())

As a suggestion, you also can use the QChar::digitValue() to obtain the numeric value of the digit. For example:

for (int var = 0; var < myString.length(); ++var) {
    bool ok;
    if (myString.at(var).isDigit()){
        int digit = myString.at(var).digitValue();
        //DO SOMETHING HERE WITH THE DIGIT
    }
}

Source: Converting one element from a QString to int

you can use QString::fromAscii()

QByteArray data = entity->getData();
QString s_data = QString::fromAscii(data.data());

with data() returning a char*

for QT5, you should use fromCString() instead, as fromAscii() is deprecated, see https://bugreports.qt-project.org/browse/QTBUG-21872 https://bugreports.qt.io/browse/QTBUG-21872

There's a caveat with the general 39 character IPv6 structure. For IPv4 mapped IPv6 addresses, the string can be longer (than 39 characters). An example to show this:

IPv6 (39 characters) :

ABCD:ABCD:ABCD:ABCD:ABCD:ABCD:ABCD:ABCD

IPv4-mapped IPv6 (45 characters) :

ABCD:ABCD:ABCD:ABCD:ABCD:ABCD:192.168.158.190

Note: the last 32-bits (that correspond to IPv4 address) can need up to 15 characters (as IPv4 uses 4 groups of 1 byte and is formatted as 4 decimal numbers in the range 0-255 separated by dots (the . character), so the maximum is DDD.DDD.DDD.DDD).

The correct maximum IPv6 string length, therefore, is 45.

This was actually a quiz question in an IPv6 training I attended. (We all answered 39!)

Swift 3.1

import UIKit

extension UILabel {
    var fontSize: CGFloat {
        get {
            return self.font.pointSize
        }
        set {
            self.font =  UIFont(name: self.font.fontName, size: newValue)!
            self.sizeToFit()
        }
    }
}

Browser security settings prevent people from modifying the displayed url directly. You could imagine the phishing vulnerabilities that would cause.

Only reliable way to change the url without changing pages is to use an internal link or hash. e.g.: http://site.com/page.html becomes http://site.com/page.html#item1 . This technique is often used in hijax(AJAX + preserve history).

When doing this I'll often just use links for the actions with the hash as the href, then add click events with jquery that use the requested hash to determine and delegate the action.

I hope that sets you on the right path.

You should add overflow property like following:

.itemconfiguration
    {   
        height: 300px; 
        overflow-y:auto;

        float:left;
        position:relative;
        margin-left:-5px;
    }

insert into MyTable(field1, field2, id_backup)
    select field1, field2, uniqueId from MyTable where uniqueId = @Id;

In python 3 this is easy

myVariable = 5
for v in locals():
  if id(v) == id("myVariable"):
    print(v, locals()[v])

this will print:

myVariable 5

The first problem is that your query string is wrong:

I think this: "INSERT INTO employee(hans,germany) values(?,?)" should be like this: "INSERT INTO employee(name,country) values(?,?)"

The other problem is that you have a parameterized PreparedStatement and you don't set the parameters before running it.

You should add these to your code:

String inserting = "INSERT INTO employee(name,country) values(?,?)";
System.out.println("insert " + inserting);//
PreparedStatement ps = con.prepareStatement(inserting); 
ps.setString(1,"hans"); // <----- this
ps.setString(2,"germany");// <---- and this
ps.executeUpdate();

In addition to all the answers above:

If you are on Android 6.0+ (API Level 23+) you have to explicitly ask for permission to access external storage. Simply having

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

in your manifest won't be enough. You also have actively request the permission in your activity:

//check for permission
if(ContextCompat.checkSelfPermission(this,
            Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_DENIED){
    //ask for permission
    requestPermissions(new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, READ_EXTERNAL_STORAGE_PERMISSION_CODE);
}

I recommend reading this: http://developer.android.com/training/permissions/requesting.html#perm-request

// wrap it in jQuery, now it's a collection
var $elements = $(someHTML);

// append to the DOM
$("#myDiv").append($elements);

// do stuff, using the initial reference
$elements.effects("highlight", {}, 2000);

I wrote a set of scripts that provides a uniform interface for both BSD and GNU version of date.

Follow command will output the Epoch seconds for the date 2010-10-02, and it works with both BSD and GNU version of date.

$ xsh /date/convert "2010-10-02" "+%s"
1286020263

It's an equivalent of the command with GNU version of date:

date -d "2010-10-02" "+%s"

and also the command with BSD version of date:

date -j -f "%F" 2010-10-02 "+%s"

The scripts can be found at:

• https://github.com/xsh-lib/core/tree/master/functions/date

It's a part of a library called xsh-lib/core. To use them you need both repos xsh and xsh-lib/core, I list them below:

Just verified this today, but if you are trying to open a Facebook page, you can use "fb://page/{Page ID}"

Page ID can be found under your page in the about section near the bottom.

Specific to my use case, in Xamarin.Forms, you can use this snippet to open in the app if available, otherwise in the browser.

Device.OpenUri(new Uri("fb://page/{id}"));

I have come up with a slightly modified version of @SebastianRittau's wonderful answer (for Python > 3.4 I think), which will allow you to load a file with any extension as a module using spec_from_loader instead of spec_from_file_location:

from importlib.util import spec_from_loader, module_from_spec
from importlib.machinery import SourceFileLoader 

spec = spec_from_loader("module.name", SourceFileLoader("module.name", "/path/to/file.py"))
mod = module_from_spec(spec)
spec.loader.exec_module(mod)

The advantage of encoding the path in an explicit SourceFileLoader is that the machinery will not try to figure out the type of the file from the extension. This means that you can load something like a .txt file using this method, but you could not do it with spec_from_file_location without specifying the loader because .txt is not in importlib.machinery.SOURCE_SUFFIXES.

Very easy no need create class extends LocationListener 1- Variable

private LocationManager mLocationManager;
private LocationListener mLocationListener;
private static double currentLat =0;
private static double currentLon =0;

2- onStartService()

@Override public void onStartService() {
    addListenerLocation();
}

3- Method addListenerLocation()

 private void addListenerLocation() {
    mLocationManager = (LocationManager)
            getSystemService(Context.LOCATION_SERVICE);
    mLocationListener = new LocationListener() {
        @Override
        public void onLocationChanged(Location location) {
            currentLat = location.getLatitude();
            currentLon = location.getLongitude();

            Toast.makeText(getBaseContext(),currentLat+"-"+currentLon, Toast.LENGTH_SHORT).show();

        }

        @Override
        public void onStatusChanged(String provider, int status, Bundle extras) {
        }

        @Override
        public void onProviderEnabled(String provider) {
            Location lastKnownLocation = mLocationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
            if(lastKnownLocation!=null){
                currentLat = lastKnownLocation.getLatitude();
                currentLon = lastKnownLocation.getLongitude();
            }

        }

        @Override
        public void onProviderDisabled(String provider) {
        }
    };
    mLocationManager.requestLocationUpdates(
            LocationManager.GPS_PROVIDER, 500, 10, mLocationListener);
}

4- onDestroy()

@Override
public void onDestroy() {
    super.onDestroy();
    mLocationManager.removeUpdates(mLocationListener);
}

Kent Beck suggests:

• One test fixture per 'unit' (class of your program). Test fixtures are classes themselves. The test fixture name should be:

  [name of your 'unit']Tests
  

• Test cases (the test fixture methods) have names like:

  test[feature being tested]
  

For example, having the following class:

class Person {
    int calculateAge() { ... }

    // other methods and properties
}

A test fixture would be:

class PersonTests {

    testAgeCalculationWithNoBirthDate() { ... }

    // or

    testCalculateAge() { ... }
}

aM Charts are also making WPF Chart controls. Currently they only show off a pie chart, but they are set to provide new ones in short term.

To complement Michael's answer, and according to this answer, a safe way to deal with the problem is to use the following arguments:

-XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled -XX:+UseConcMarkSweepGC

Personally, I just use JSON to convert things to strings and back. Strings I understand.

import json
s = [('yellow', 1), ('blue', 2), ('yellow', 3), ('blue', 4), ('red', 1)]
mydict = {}
hash = json.dumps(s)
mydict[hash] = "whatever"
print mydict
#{'[["yellow", 1], ["blue", 2], ["yellow", 3], ["blue", 4], ["red", 1]]': 'whatever'}

I had a similar situation where I wanted to replace a URL query parameter. However, I only had one param, and I could simply replace it:

window.location.search = '?filter=' + my_filter_value

The location.search property allows you to get or set the query portion of a URL.

In classic sh, you have to do something like:

s=test1
s="${s}test2"

(there are lots of variations on that theme, like s="$s""test2")

In bash, you can use +=:

s=test1
s+=test2

I think you want this:

foreach ($myarray as $key => $value) {
    echo "$key = $value\n";
}

UINavigationBar *nbar = self.navigationController.navigationBar;

if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
   //iOS 7
   nbar.barTintColor = [UIColor blueColor]; // bar color
   //or custom color 
   //[UIColor colorWithRed:19.0/255.0 green:86.0/255.0 blue:138.0/255.0 alpha:1];

   nbar.navigationBar.translucent = NO;

   nbar.tintColor = [UIColor blueColor]; //bar button item color

} else {
   //ios 4,5,6
   nbar.tintColor = [UIColor whiteColor];
   //or custom color
   //[UIColor colorWithRed:19.0/255.0 green:86.0/255.0 blue:138.0/255.0 alpha:1];

}

Use this:

bucket = [None] * 100
for i in range(100):
    bucket[i] = [None] * 100

OR

w, h = 100, 100
bucket = [[None] * w for i in range(h)]

Both of them will output proper empty multidimensional bucket list 100x100

Imagine that we want to apply a series of functions to x if and only if x is non-null:

if (x !== null) x = a(x);
if (x !== null) x = b(x);
if (x !== null) x = c(x);

Now let's say that we need to do the same to y:

if (y !== null) y = a(y);
if (y !== null) y = b(y);
if (y !== null) y = c(y);

And the same to z:

if (z !== null) z = a(z);
if (z !== null) z = b(z);
if (z !== null) z = c(z);

As you can see without a proper abstraction, we'll end up duplicating code over and over again. Such an abstraction already exists: the Maybe monad.

The Maybe monad holds both a value and a computational context:

1. The monad keeps the value safe and applies functions to it.
2. The computational context is a null check before applying a function.

A naive implementation would look like this:

?? This implementation is for illustration purpose only! This is not how it should be done and is wrong at many levels. However this should give you a better idea of what I am talking about.

As you can see nothing can break:

1. We apply a series of functions to our value
2. If at any point, the value becomes null (or undefined) we just don't apply any function anymore.

const abc = obj =>_x000D_
  Maybe_x000D_
    .of(obj)_x000D_
    .map(o => o.a)_x000D_
    .map(o => o.b)_x000D_
    .map(o => o.c)_x000D_
    .value;_x000D_

_x000D_
console.log(_x000D_
_x000D_
  values.map(abc)_x000D_
_x000D_
);

<script>_x000D_
function Maybe(x) {_x000D_
  this.value = x; //-> container for our value_x000D_
}_x000D_
_x000D_
Maybe.of = x => new Maybe(x);_x000D_
_x000D_
Maybe.prototype.map = function (fn) {_x000D_
  if (this.value == null) { //-> computational context_x000D_
    return this;_x000D_
  }_x000D_
  return Maybe.of(fn(this.value));_x000D_
};_x000D_
</script>

Appendix 1

I cannot explain what monads are as this is not the purpose of this post and there are people out there better at this than I am. However as Eric Elliot said in hist blog post JavaScript Monads Made Simple:

Regardless of your skill level or understanding of category theory, using monads makes your code easier to work with. Failing to take advantage of monads may make your code harder to work with (e.g., callback hell, nested conditional branches, more verbosity).

Appendix 2

Here's how I'd solve your issue using the Maybe monad from monetjs

const prop = key => obj => Maybe.fromNull(obj[key]);_x000D_
_x000D_
const abc = obj =>_x000D_
  Maybe_x000D_
    .fromNull(obj)_x000D_
    .flatMap(prop('a'))_x000D_
    .flatMap(prop('b'))_x000D_
    .flatMap(prop('c'))_x000D_
    .orSome('')_x000D_
    _x000D_
const values = [_x000D_
  {},_x000D_
  {a: {}},_x000D_
  {a: {b: {}}},_x000D_
  {a: {b: {c: 42}}}_x000D_
];_x000D_
_x000D_
console.log(_x000D_
_x000D_
  values.map(abc)_x000D_
_x000D_
);

Use separate handler, say:

function myOnClickHandler(th){
//say let t=$(th)
}

and in html do this:

<...onclick="myOnClickHandler(this); event.stopPropagation();"...>

Or even :

function myOnClickHandler(e){
  e.stopPropagation();
}

for:

<...onclick="myOnClickHandler(event)"...>

I know this question posted long time ago.

I had similar problem few days ago, passing value from web service in json format and place it in table cell contentText.

Because value is passed in format, for example, "text row1\r\ntext row2" and so on.

For new line in textContent You have to use \r\n and, finally, I had to use css white-space: pre-line; (Text will wrap when necessary, and on line breaks) and everything goes fine.

Or, You can use only white-space: pre; and then text will wrap only on line breaks (in this case \r\n).

So, there is example how to solve it with wrapping text only on line breaks :

var h1 = document.createElement("h1");_x000D_
_x000D_
//setting this css style solving problem with new line in textContent_x000D_
h1.setAttribute('style', 'white-space: pre;');_x000D_
_x000D_
//add \r\n in text everywhere You want for line-break (new line)_x000D_
h1.textContent = "This is a very long string and I would like to insert a carriage return \r\n...";_x000D_
h1.textContent += "moreover, I would like to insert another carriage return \r\n...";_x000D_
h1.textContent += "so this text will display in a new line";_x000D_
_x000D_
document.body.appendChild(h1);

Just add the CSS rule (and the slightly improved mark-up) posted below and you should get the result that you're after.

CSS

.blank_row
{
    height: 10px !important; /* overwrites any other rules */
    background-color: #FFFFFF;
}

HTML

<tr class="blank_row">
    <td colspan="3"></td>
</tr>

Since I have no idea what your current stylesheet looks like I added the !important property just in case. If possible, though, you should remove it as one rarely wants to rely on !important declarations in a stylesheet considering the big possibility that they will mess it up later on.

Just add some headers before sending mail:

<?php 
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
$from = 'From: yoursite.com'; 
$to = '[email protected]'; 
$subject = 'Customer Inquiry';
$body = "From: $name\n E-Mail: $email\n Message:\n $message";

$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html\r\n";
$headers .= 'From: [email protected]' . "\r\n" .
'Reply-To: [email protected]' . "\r\n" .
'X-Mailer: PHP/' . phpversion();

mail($to, $subject, $message, $headers);

And one more thing. The mail() function is not working in localhost. Upload your code to a server and try.

Generally if the installation went smoothly, it will create the desktop icons/folders. Maybe check the installation summary log to see if there's any underlying errors.

I am installing pyfuzzybut is is not in PyPI; it returns the message: No matching distribution found for pyfuzzy.

I tried the accepted answer

pip install  --no-index --find-links=file:///Users/victor/Downloads/pyfuzzy-0.1.0 pyfuzzy

But it does not work either and returns the following error:

Ignoring indexes: https://pypi.python.org/simple Collecting pyfuzzy Could not find a version that satisfies the requirement pyfuzzy (from versions: ) No matching distribution found for pyfuzzy

At last , I have found a simple good way there: https://pip.pypa.io/en/latest/reference/pip_install.html

Install a particular source archive file.
$ pip install ./downloads/SomePackage-1.0.4.tar.gz
$ pip install http://my.package.repo/SomePackage-1.0.4.zip

So the following command worked for me:

pip install ../pyfuzzy-0.1.0.tar.gz.

Hope it can help you.

An INNER JOIN can return data from the columns from both tables, and can duplicate values of records on either side have more than one match. A LEFT SEMI JOIN can only return columns from the left-hand table, and yields one of each record from the left-hand table where there is one or more matches in the right-hand table (regardless of the number of matches). It's equivalent to (in standard SQL):

SELECT name
FROM table_1 a
WHERE EXISTS(
    SELECT * FROM table_2 b WHERE (a.name=b.name))

If there are multiple matching rows in the right-hand column, an INNER JOIN will return one row for each match on the right table, while a LEFT SEMI JOIN only returns the rows from the left table, regardless of the number of matching rows on the right side. That's why you're seeing a different number of rows in your result.

I am trying to get the names within table_1 that only appear in table_2.

Then a LEFT SEMI JOIN is the appropriate query to use.

That is invalid syntax. You are mixing relational expressions with scalar operators (OR). Specifically you cannot combine expr IN (select ...) OR (select ...). You probably want expr IN (select ...) OR expr IN (select ...). Using union would also work: expr IN (select... UNION select...)

Open Advanced Mode in the Groupings pane. (Click the arrow to the right of the Column Groups and select Advanced Mode.)

In the Row Groups area (not Column Groups), click on a Static group, which highlights the corresponding textbox in the tablix.

Click through each Static group until it highlights the leftmost column header. This is generally the first Static group listed.

In the properties grid:

• set KeepWithGroup to After
• set RepeatOnNewPage to True for repeating headers
• set FixedData to True for keeping headers visible

You can write the where clause as:

where (case when (:stateCode = '') then (1)
            when (:stateCode != '') and (vw.state_cd in (:stateCode)) then 1
            else 0)
       end) = 1;

Alternatively, remove the case entirely:

where (:stateCode = '') or
      ((:stateCode != '') and vw.state_cd in (:stateCode));

Or, even better:

where (:stateCode = '') or vw.state_cd in (:stateCode)

In case the container is already running:

docker exec -it container_id_or_name ash

The limitation relates to the simplified CommonJS syntax vs. the normal callback syntax:

• http://requirejs.org/docs/whyamd.html#commonjscompat
• https://github.com/jrburke/requirejs/wiki/Differences-between-the-simplified-CommonJS-wrapper-and-standard-AMD-define

Loading a module is inherently an asynchronous process due to the unknown timing of downloading it. However, RequireJS in emulation of the server-side CommonJS spec tries to give you a simplified syntax. When you do something like this:

var foomodule = require('foo');
// do something with fooModule

What's happening behind the scenes is that RequireJS is looking at the body of your function code and parsing out that you need 'foo' and loading it prior to your function execution. However, when a variable or anything other than a simple string, such as your example...

var module = require(path); // Call RequireJS require

...then Require is unable to parse this out and automatically convert it. The solution is to convert to the callback syntax;

var moduleName = 'foo';
require([moduleName], function(fooModule){
    // do something with fooModule
})

Given the above, here is one possible rewrite of your 2nd example to use the standard syntax:

define(['dyn_modules'], function (dynModules) {
    require(dynModules, function(){
        // use arguments since you don't know how many modules you're getting in the callback
        for (var i = 0; i < arguments.length; i++){
            var mymodule = arguments[i];
            // do something with mymodule...
        }
    });

});

EDIT: From your own answer, I see you're using underscore/lodash, so using _.values and _.object can simplify the looping through arguments array as above.

Try something like below

 <a href="#" onclick="this.forms['formName'].submit()">Submit</a> 

<table>
<tr><td><img ...><td><img ...>
<tr><td>caption1<td>caption2
</table>

Style as desired.

SqlBulkCopy class is best for SQL server,

Doing Bulk Upload/Insert of DataTable to a Table in SQL server in C#

You could do something like this:

my $data = <<END;
1) Scheme ID: abc-456-hu5t10 (High priority) *
2) Scheme ID: frt-78f-hj542w (Balanced)
3) Scheme ID: 23f-f974-nm54w (super formula run) *

  my ($id,$word,$star) = ($1,$2,$3);
  print "$id $word $star\n";
}

The key thing is the Regular expression:

Scheme ID: ([a-z0-9-]+)\s+\(([^)]+)\)\s*(\*)?

Which breaks up as follows.

The fixed String "Scheme ID: ":

Followed by one or more whitespace characters:

\s+

Followed by an opening bracket (which we escape) followed by any number of characters which aren't a close bracket, and then a closing bracket (escaped). We use unescaped brackets to capture the words as $2:

\(([^)]+)\)

Followed by some spaces any maybe a *, captured as $3:

\s*(\*)?

There is a very simple solution using dense_rank()

dense_rank() over (partition by [Mth] order by [UserAccountKey]) 
+ dense_rank() over (partition by [Mth] order by [UserAccountKey] desc) 
- 1

This will give you exactly what you were asking for: The number of distinct UserAccountKeys within each month.

If for whatever reason you'd like to catch the output of Console.WriteLine, you CAN do this:

protected void Application_Start(object sender, EventArgs e)
{
    var writer = new LogWriter();
    Console.SetOut(writer);
}

public class LogWriter : TextWriter
{
    public override void WriteLine(string value)
    {
        //do whatever with value
    }

    public override Encoding Encoding
    {
        get { return Encoding.Default; }
    }
}

Python has a built in min function to help you with finding the smallest.

However, you need to convert your list items to numbers before you can find the lowest integer( what, isn't that float? )

min(float(i) for i in l)

my tabs were in panels, so i added a class='disabled' to the tabs anchor

in javascript i added:

$(selector + ' a[data-toggle="tab"]').on('show.bs.tab', function (e) {
    if ($(this).hasClass('disabled')){
        e.preventDefault();
        return false;
    }
})

and for presentation in less i added:

.panel-heading{
    display:table;
    width:100%;
    padding-bottom:10px;
    ul.nav-tabs{
        display:table-cell;
        vertical-align:bottom;
        a.disabled{
            .text-muted;
            cursor:default;
            &:hover{
                background-color:transparent;
                border:none;
            }
        }
    }
}

Change the active scheme Device from Simulator to Generic iOS Device

None of the answers address the point of this design choice. I think docker works this way to prevent these 2 errors:

• Repeated restart
• Partial error

You can also do this without cat, though honestly cat is more readable:

>> file1 < file2

The >> appends STDIN to file1 and the < dumps file2 to STDIN.

Yes, you can use numpy for that.

import numpy as np
a = arange(3,dtype=float)

a[0] = np.nan
a[1] = np.inf
a[2] = -np.inf

a # is now [nan,inf,-inf]

np.isnan(a[0]) # True
np.isinf(a[1]) # True
np.isinf(a[2]) # True

I faced same issue few days back, I followed the link mentioned below and I could able to overcome the problem

http://www.baeldung.com/spring-data-jpa-multiple-databases

void ExplodeString( const std::string& string, const char separator, std::list<int>& result ) {
    if( string.size() ) {
        std::string::const_iterator last = string.begin();
        for( std::string::const_iterator i=string.begin(); i!=string.end(); ++i ) {
            if( *i == separator ) {
                const std::string str(last,i);
                int id = atoi(str.c_str());
                result.push_back(id);
                last = i;
                ++ last;
            }
        }
        if( last != string.end() ) result.push_back( atoi(&*last) );
    }
}

Mutations expect two arguments: state and payload, where the current state of the store is passed by Vuex itself as the first argument and the second argument holds any parameters you need to pass.

The easiest way to pass a number of parameters is to destruct them:

mutations: {
    authenticate(state, { token, expiration }) {
        localStorage.setItem('token', token);
        localStorage.setItem('expiration', expiration);
    }
}

Then later on in your actions you can simply

store.commit('authenticate', {
    token,
    expiration,
});

In my case, the solution was to make every directory in the directory path readable and accessible by mysql (chmod a+rx). The directory was still specified by its relative path in the command line.

chmod a+rx /tmp
chmod a+rx /tmp/migration
etc.

var src = $('img.conversation_img[alt="example"]').attr('src');

If you have multiple matching elements only the src of the first one will be returned.

You can use a User-defined function or a view instead of a procedure.

A procedure can return multiple result sets, each with its own schema. It's not suitable for using in a SELECT statement.

how about hidden span tags with linkable IDs that provide the height of the navbar:

#head1 {
  padding-top: 60px;
  height: 0px;
  visibility: hidden;
}


<span class="head1">somecontent</span>
<h5 id="headline1">This Headline is not obscured</h5>

heres the fiddle: http://jsfiddle.net/N6f2f/7

I've written a library that helps do precisely this. It allows search by object simply by initializing only the fields you want to filter by: https://github.com/kg6zvp/GenericEntityEJB

As per documentation:

MySQL Docs

• The SELECT statement cannot contain a subquery in the FROM clause.

Your workaround would be to create a view for each of your subqueries.

Then access those views from within your view view_credit_status

Building on Roland's answer, using tidyr to reshape the data from wide to long:

library(tidyr)
library(ggplot2)

df <- read.table(text="Rank F1     F2     F3
1    500    250    50
2    400    100    30
3    300    155    100
4    200    90     10", header=TRUE)

df %>% 
  gather(variable, value, F1:F3) %>% 
  ggplot(aes(x = Rank, y = value, fill = variable)) + 
  geom_bar(stat = "identity")

You need to use JSONObject like below:

String mJsonString = downloadFileFromInternet(urls[0]);

JSONObject jObject = null;
try {
    jObject = new JSONObject(mJsonString);
} 
catch (JSONException e) {
    e.printStackTrace();
    return false;
}

...

private String downloadFileFromInternet(String url)
{
    if(url == null /*|| url.isEmpty() == true*/)
        new IllegalArgumentException("url is empty/null");
    StringBuilder sb = new StringBuilder();
    InputStream inStream = null;
    try
    {
        url = urlEncode(url);
        URL link = new URL(url);
        inStream = link.openStream();
        int i;
        int total = 0;
        byte[] buffer = new byte[8 * 1024];
        while((i=inStream.read(buffer)) != -1)
        {
            if(total >= (1024 * 1024))
            {
                return "";
            }
            total += i;
            sb.append(new String(buffer,0,i));
        }
    }
    catch(Exception e )
    {
        e.printStackTrace();
        return null;
    }catch(OutOfMemoryError e)
    {
        e.printStackTrace();
        return null;
    }
    return sb.toString();
}

private String urlEncode(String url)
{
    if(url == null /*|| url.isEmpty() == true*/)
        return null;
    url = url.replace("[","");
    url = url.replace("]","");
    url = url.replaceAll(" ","%20");
    return url;
}

Hope this helps you..

This should do it for you:

Declare @DatePeriod datetime

Set @DatePeriod = '2011-05-30'

Select  ProductName,
        IsNull([1],0) as 'Week 1',
        IsNull([2],0) as 'Week 2',
        IsNull([3],0) as 'Week 3',
        IsNull([4],0) as 'Week 4',
        IsNull([5], 0) as 'Week 5'

From 
(
Select  ProductName,
        DATEDIFF(week, DATEADD(MONTH, DATEDIFF(MONTH, 0, InputDate), 0), InputDate) +1 as [Weeks],
        Sale as 'Sale'

From dbo.YourTable
-- Only get rows where the date is the same as the DatePeriod
-- i.e DatePeriod is 30th May 2011 then only the weeks of May will be calculated
Where DatePart(Month, InputDate)= DatePart(Month, @DatePeriod)
)p 
Pivot (Sum(Sale) for Weeks in ([1],[2],[3],[4],[5])) as pv

It will calculate the week number relative to the month. So instead of week 20 for the year it will be week 2. The @DatePeriod variable is used to fetch only rows relative to the month (in this example only for the month of May)

Output using my sample data:

whenever you deal with spaces in filenames, use quotes

net use "m:\Server01\my folder" /USER:mynetwork\Administrator "Mypassword" /persistent:yes

If you ever end up with the same problem with Scala and SBT:

• Go to Project Structure. The shortcut is (CTRL + ALT + SHIFT + S)

• On the far left list, choose Project Settings > Modules

• On the module list right of that, select the module of your project name (without the build) and choose the sources tab

• In middle, expand the folder that the root of your project for me that's /home/<username>/IdeaProjects/<projectName>

• Look at the Content Root section on the right side, the red paths are directories that you haven't made. You'll want to put the properties file in a Resources directory. So I created src/main/resources and put log4j.properties in it. I believe you can also modify the Content Root to put it wherever you want (I didn't do this).

• I ran my code with a SBT configuration and it found my log4j.properties file.

              ", " + 
              MouseInfo.getPointerInfo().getLocation().y + ")");
    }
  }
}

If your aim is to redirect all pages to a single maintenance page (as the title could suggest also this), then use:

RewriteEngine on
RewriteCond %{REQUEST_URI} !/maintenance.php$ 
RewriteCond %{REMOTE_HOST} !^000\.000\.000\.000
RewriteRule $ /maintenance.php [R=302,L] 

Where 000 000 000 000 should be replaced by your ip adress.

To find them, you can use this

;WITH cte AS
(
   SELECT 0 AS CharCode
   UNION ALL
   SELECT CharCode + 1 FROM cte WHERE CharCode <31
)
SELECT
   *
FROM
   mytable T
     cross join cte
WHERE
   EXISTS (SELECT *
        FROM mytable Tx
        WHERE Tx.PKCol = T.PKCol
             AND
              Tx.MyField LIKE '%' + CHAR(cte.CharCode) + '%'
         )

Replacing the EXISTS with a JOIN will allow you to REPLACE them, but you'll get multiple rows... I can't think of a way around that...

None of the answers here worked for me. Using FormDataCollection in the post method seems like the right answer but something about my post request was causing webapi to choke. eventually I made it work by including no parameters in the method call and just manually parsing out the form parameters like this.

public HttpResponseMessage FileUpload() {
    System.Web.HttpRequest httpRequest = System.Web.HttpContext.Current.Request;
    System.Collections.Specialized.NameValueCollection formData = httpRequest.Form;
    int ID = Convert.ToInt32(formData["ID"]);
    etc

Lets address the two use cases

**Rename a package name or Trim a package **

com.mycompany.mystupidapplicationname to com.mycompany.brandname

or

com.someothercompany.mystupidapplicationname to com.someothercompany.mystupidapplicationname

or

com.someothercompany.mystupidapplicationname to someothercompany.brandname

1. Select Package in the drop down in Android Studio

2. Right click on the package which contains your MainActivity and refractor it

3. Select Rename Package and everything will work like a charm

But this will only rename the last part of package name

4. To rename the first or second part of package name . Create a new dummy file in the part of package which you want to rename. the file will be created inside mycompany.com.myapplicationame. Then move the file inside mycompany(right click => move) to make mycompany appear in tree view. This will make that part part of the tree view and will you help you to do a right click and rename that part.

5. Delete the dummy file

6. To Trim a package , simply right click and move the package part inside its grand parent

In my case these two options worked.

1. in //@ComponentScan ({"myapp", "myapp.resources","myapp.services"}) include also the package which holds the Application.class in the list, or

2. Simply add @EnableAutoConfiguration; it automatically recognizes all the spring beans.

It is possible to query this information from WMI. The following command will output a table with a row for every user along with the SID for each user.

wmic useraccount get name,sid

You can also export this information to CSV:

wmic useraccount get name,sid /format:csv > output.csv

I have used this on Vista and 7. For more information see WMIC - Take Command-line Control over WMI.

Pitfall:

1. Using your own html element like <my-directive></my-directive> wont work on IE8 without workaround (https://docs.angularjs.org/guide/ie)
2. Using your own html elements will make html validation fail.
3. Directives with equal one parameter can done like this:

<div data-my-directive="ValueOfTheFirstParameter"></div>

Instead of this:

<my-directive my-param="ValueOfTheFirstParameter"></my-directive>

We dont use custom html elements, because if this 2 facts.

Every directive by third party framework can be written in two ways:

<my-directive></my-directive>

or

<div data-my-directive></div>

does the same.

As another clue, that indeed fixed this issue in my case.

I'm migrating some WCF services from a console application (that configures in code few WCF services) to an Azure WebRole to publish them in Azure. Every time I add a new service VS edits my web.config and adds this line:

<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true">

Well, with all the advices and answers above I couldn't make it work until I removed all the attributes in the serviceHostingEnvironment element. As you can see I'm not a WCF rockstar but I made it to work with the first Service just by configuring it as:

<service name="FirstService" behaviorConfiguration="metadataBehavior">
                <endpoint address=""
                 binding="wsHttpBinding"
                 bindingConfiguration="WSHttpBinding_WcfServicesBinding"
                 contract="IFirstService" />

            </service>

but when I added the second Service it stoped working and I realized that those attributes where there again.

I hope it saves you time.

SET IDENTITY_INSERT tableA ON

INSERT Into tableA ([id], [c2], [c3], [c4], [c5] ) 
SELECT [id], [c2], [c3], [c4], [c5] FROM tableB

Not like this

INSERT INTO tableA
SELECT * FROM tableB

SET IDENTITY_INSERT tableA OFF

This is a server side issue. You don't need to add any headers in angular for cors. You need to add header on the server side:

Access-Control-Allow-Headers: Content-Type
Access-Control-Allow-Methods: GET, POST, OPTIONS
Access-Control-Allow-Origin: *

window.onload=function() { // or window.addEventListener("load",function() {

When using fixed-format dates you need to set the date formatter locale to "en_US_POSIX".

Taken from the Data Formatting Guide

If you're working with fixed-format dates, you should first set the locale of the date formatter to something appropriate for your fixed format. In most cases the best locale to choose is en_US_POSIX, a locale that's specifically designed to yield US English results regardless of both user and system preferences. en_US_POSIX is also invariant in time (if the US, at some point in the future, changes the way it formats dates, en_US will change to reflect the new behavior, but en_US_POSIX will not), and between platforms (en_US_POSIX works the same on iPhone OS as it does on OS X, and as it does on other platforms).

Swift 3 or later

extension Formatter {
    static let customDate: DateFormatter = {
        let formatter = DateFormatter()
        formatter.locale = Locale(identifier: "en_US_POSIX")
        formatter.dateFormat = "dd/MM/yy"
        return formatter
    }()
    static let time: DateFormatter = {
        let formatter = DateFormatter()
        formatter.locale = Locale(identifier: "en_US_POSIX")
        formatter.dateFormat = "HH:mm"
        return formatter
    }()
    static let weekdayName: DateFormatter = {
        let formatter = DateFormatter()
        formatter.dateFormat = "cccc"
        return formatter
    }()
    static let month: DateFormatter = {
        let formatter = DateFormatter()
        formatter.dateFormat = "LLLL"
        return formatter
    }()
}

extension Date {
    var customDate: String {
        return Formatter.customDate.string(from: self)
    }
    var customTime: String {
        return Formatter.time.string(from: self)
    }
    var weekdayName: String {
        return Formatter.weekdayName.string(from: self)
    }
    var monthName: String {
        return Formatter.month.string(from: self)
    }
}

extension String {
    var customDate: Date? {
        return Formatter.customDate.date(from: self)
    }
}

usage:

// this will be displayed like this regardless of the user and system preferences
Date().customTime          //  "16:50"
Date().customDate          //  "06/05/17"
// this will be displayed according to user and system preferences
Date().weekdayName         //  "Saturday"
Date().monthName           //  "May"

Parsing the custom date and converting the date back to the same string format:

let dateString = "01/02/10"

if let date = dateString.customDate {
    print(date.customDate)   // "01/02/10\n"
    print(date.monthName)    // customDate
}

Here it is all elements you can use to customize it as necessary:

There's a couple ways of doing this. As long as the WAR file is expanded (a set of files instead of one .war file), you can use this API:

ServletContext context = getContext();
String fullPath = context.getRealPath("/WEB-INF/test/foo.txt");

http://tomcat.apache.org/tomcat-5.5-doc/servletapi/javax/servlet/ServletContext.html#getRealPath(java.lang.String)

That will get you the full system path to the resource you are looking for. However, that won't work if the Servlet Container never expands the WAR file (like Tomcat). What will work is using the ServletContext's getResource methods.

ServletContext context = getContext();
URL resourceUrl = context.getResource("/WEB-INF/test/foo.txt");

or alternatively if you just want the input stream:

InputStream resourceContent = context.getResourceAsStream("/WEB-INF/test/foo.txt");

http://tomcat.apache.org/tomcat-5.5-doc/servletapi/javax/servlet/ServletContext.html#getResource(java.lang.String)

The latter approach will work no matter what Servlet Container you use and where the application is installed. The former approach will only work if the WAR file is unzipped before deployment.

EDIT: The getContext() method is obviously something you would have to implement. JSP pages make it available as the context field. In a servlet you get it from your ServletConfig which is passed into the servlet's init() method. If you store it at that time, you can get your ServletContext any time you want after that.

Thank you so much for that class, Cristian.

I made a minor tweak to it so that the custom loading view is optional, like so:

  @Override
    public View getVideoLoadingProgressView() // Video will start loading, only called in the case of VideoView (typically API level 10-)
    {
        if (loadingView == null)
        {
            return super.getVideoLoadingProgressView();
        }
        else
        {
            loadingView.setVisibility(View.VISIBLE);
            return loadingView;
        }
    }

I also added a new constructor that just takes two parameters. Anyway, just a minor simplification if you don't need the loading view. Thanks again for providing this.

This should do it:

try {
    driver.findElement(By.id(id));
} catch (NoSuchElementException e) {
    //do what you need here if you were expecting
    //the element wouldn't exist
}

Add a double quotes outside the brackets and replace double quotes inside the {} with \"

So: "{\"data\":{..... }"

As stated before, SQL Server doesn't implement the ANSI standard when it comes to UNIQUE CONSTRAINT. There is a ticket on Microsoft Connect for this since 2007. As suggested there and here the best options as of today are to use a filtered index as stated in another answer or a computed column, e.g.:

CREATE TABLE [Orders] (
  [OrderId] INT IDENTITY(1,1) NOT NULL,
  [TrackingId] varchar(11) NULL,
  ...
  [ComputedUniqueTrackingId] AS (
      CASE WHEN [TrackingId] IS NULL
      THEN '#' + cast([OrderId] as varchar(12))
      ELSE [TrackingId_Unique] END
  ),
  CONSTRAINT [UQ_TrackingId] UNIQUE ([ComputedUniqueTrackingId])
)

I unable to comment on the top answer, but Excel actually lets you do this without adding the ugly conditional logic.

Conditional formatting is automatically applied to any input that isn't an error, so you can achieve the same effect as:

=NOT(ISERROR(MATCH(A1,$B$1:$B$1000,0)))

With this:

= MATCH(A1,$B$1:$B$1000,0)))

If the above is applied to your data, A1 will be formatted if it matches any cell in $B$1:$B$1000, as any non-match will return an error.

        try(FileSystem fs = FileSystems.newFileSystem(
                uri, Collections.<String,Object>emptyMap())) {
            Path p = fs.provider().getPath(uri);
            action.accept(p);
        }
    }
}

The main obstacle is to deal with the two possibilities, either, having an existing filesystem that we should use, but not close (like with file URIs or the Java 9’s module storage), or having to open and thus safely close the filesystem ourselves (like zip/jar files).

Therefore, the solution above encapsulates the actual action in an interface, handles both cases, safely closing afterwards in the second case, and works from Java 7 to Java 10. It probes whether there is already an open filesystem before opening a new one, so it also works in the case that another component of your application has already opened a filesystem for the same zip/jar file.

It can be used in all Java versions named above, e.g. to listing the contents of a package (java.lang in the example) as Paths, like this:

processRessource(Object.class.getResource("Object.class").toURI(), new IOConsumer<Path>() {
    public void accept(Path path) throws IOException {
        try(DirectoryStream<Path> ds = Files.newDirectoryStream(path.getParent())) {
            for(Path p: ds)
                System.out.println(p);
        }
    }
});

With Java 8 or newer, you can use lambda expressions or method references to represent the actual action, e.g.

processRessource(Object.class.getResource("Object.class").toURI(), path -> {
    try(Stream<Path> stream = Files.list(path.getParent())) {
        stream.forEach(System.out::println);
    }
});

to do the same.

The final release of Java 9’s module system has broken the above code example. The JRE inconsistently returns the path /java.base/java/lang/Object.class for Object.class.getResource("Object.class") whereas it should be /modules/java.base/java/lang/Object.class. This can be fixed by prepending the missing /modules/ when the parent path is reported as non-existent:

processRessource(Object.class.getResource("Object.class").toURI(), path -> {
    Path p = path.getParent();
    if(!Files.exists(p))
        p = p.resolve("/modules").resolve(p.getRoot().relativize(p));
    try(Stream<Path> stream = Files.list(p)) {
        stream.forEach(System.out::println);
    }
});

Then, it will again work with all versions and storage methods.

You usually don't want to do this. With Docker Compose you define services that compose your app. npm and manage.py are just management commands. You don't need a container for them. If you need to, say create your database tables with manage.py, all you have to do is:

docker-compose run client python manage.py create_db

Think of it as the one-off dynos Heroku uses.

If you really need to treat these management commands as separate containers (and also use Docker Compose for these), you could create a separate .yml file and start Docker Compose with the following command:

docker-compose up -f my_custom_docker_compose.yml

As I did not see the correct implementation, I recoded mine this way...

    def age_in_years(from_date, to_date=datetime.date.today()):
  if (DEBUG):
    logger.debug("def age_in_years(from_date='%s', to_date='%s')" % (from_date, to_date))

  if (from_date>to_date): # swap when the lower bound is not the lower bound
    logger.debug('Swapping dates ...')
    tmp = from_date
    from_date = to_date
    to_date = tmp

  age_delta = to_date.year - from_date.year
  month_delta = to_date.month - from_date.month
  day_delta = to_date.day - from_date.day

  if (DEBUG):
    logger.debug("Delta's are : %i  / %i / %i " % (age_delta, month_delta, day_delta))

  if (month_delta>0  or (month_delta==0 and day_delta>=0)): 
    return age_delta 

  return (age_delta-1)

Assumption of being "18" on the 28th of Feb when born on the 29th is just wrong. Swapping the bounds can be left out ... it is just a personal convenience for my code :)

Are you just trying to derive from Area<int>? In which case you do this:

class Rectangle : public Area<int>
{
    // ...
};

EDIT: Following the clarification, it seems you're actually trying to make Rectangle a template as well, in which case the following should work:

template <typename T>
class Rectangle : public Area<T>
{
    // ...
};

In 3 words: inline-block is better.

Inline Block

The only drawback to the display: inline-block approach is that in IE7 and below an element can only be displayed inline-block if it was already inline by default. What this means is that instead of using a <div> element you have to use a <span> element. It's not really a huge drawback at all because semantically a <div> is for dividing the page while a <span> is just for covering a span of a page, so there's not a huge semantic difference. A huge benefit of display:inline-block is that when other developers are maintaining your code at a later point, it is much more obvious what display:inline-block and text-align:right is trying to accomplish than a float:left or float:right statement. My favorite benefit of the inline-block approach is that it's easy to use vertical-align: middle, line-height and text-align: center to perfectly center the elements, in a way that is intuitive. I found a great blog post on how to implement cross-browser inline-block, on the Mozilla blog. Here is the browser compatibility.

Float

The reason that using the float method is not suited for layout of your page is because the float CSS property was originally intended only to have text wrap around an image (magazine style) and is, by design, not best suited for general page layout purposes. When changing floated elements later, sometimes you will have positioning issues because they are not in the page flow. Another disadvantage is that it generally requires a clearfix otherwise it may break aspects of the page. The clearfix requires adding an element after the floated elements to stop their parent from collapsing around them which crosses the semantic line between separating style from content and is thus an anti-pattern in web development.

Any white space problems mentioned in the link above could easily be fixed with the white-space CSS property.

Edit:

SitePoint is a very credible source for web design advice and they seem to have the same opinion that I do:

If you’re new to CSS layouts, you’d be forgiven for thinking that using CSS floats in imaginative ways is the height of skill. If you have consumed as many CSS layout tutorials as you can find, you might suppose that mastering floats is a rite of passage. You’ll be dazzled by the ingenuity, astounded by the complexity, and you’ll gain a sense of achievement when you finally understand how floats work.

Don’t be fooled. You’re being brainwashed.

2015 Update - Flexbox is a good alternative for modern browsers:

.container {
  display: flex; /* or inline-flex */
}

.item {
  flex: none | [ <'flex-grow'> <'flex-shrink'>? || <'flex-basis'> ]
}

Dec 21, 2016 Update

Bootstrap 4 is removing support for IE9, and thus is getting rid of floats from rows and going full Flexbox.

if you want to save workbook with no macros and no pop-up use this

Sub save()
    Application.DisplayAlerts = False
    ActiveWorkbook.SaveAs Filename:="C:\Users\" & Environ$("username") & _
    "\Desktop\" & Range("C5").Text & Chr(32) & Range("C8").Text & ".xls", _
    FileFormat:=xlOpenXMLWorkbook, CreateBackup:=False

Use command substitution like this:

line=$(sed -n '2p' myfile)
echo "$line"

Also note that there is no space around the = sign.

Steps to install curl in windows

Install cURL on Windows

There are 4 steps to follow to get cURL installed on Windows.

Step 1 and Step 2 is to install SSL library. Step 3 is to install cURL. Step 4 is to install a recent certificate

Step One: Install Visual C++ 2008 Redistributables

From https://www.microsoft.com/en-za/download/details.aspx?id=29 For 64bit systems Visual C++ 2008 Redistributables (x64) For 32bit systems Visual C++ 2008 Redistributables (x32)

Step Two: Install Win(32/64) OpenSSL v1.0.0k Light

From http://www.shininglightpro.com/products/Win32OpenSSL.html For 64bit systems Win64 OpenSSL v1.0.0k Light For 32bit systems Win32 OpenSSL v1.0.0k Light

Step Three: Install cURL

Depending on if your system is 32 or 64 bit, download the corresponding** curl.exe.** For example, go to the Win64 - Generic section and download the Win64 binary with SSL support (the one where SSL is not crossed out). Visit http://curl.haxx.se/download.html

Copy curl.exe to C:\Windows\System32

Step Four: Install Recent Certificates

Do not skip this step. Download a recent copy of valid CERT files from https://curl.haxx.se/ca/cacert.pem Copy it to the same folder as you placed curl.exe (C:\Windows\System32) and rename it as curl-ca-bundle.crt

If you have already installed curl or after doing the above steps, add the directory where it's installed to the windows path:

1 - From the Desktop, right-click My Computer and click Properties.
2 - Click Advanced System Settings .
3 - In the System Properties window click the Environment Variables button.
4 - Select Path and click Edit.
5 - Append ;c:\path to curl directory at the end.
5 - Click OK.
6 - Close and re-open the command prompt

There's something overly verbose to me about the if ((x & y) == y)... construct, especially if x AND y are both compound sets of flags and you only want to know if there's any overlap.

In this case, all you really need to know is if there's a non-zero value[1] after you've bitmasked.

[1] See Jaime's comment. If we were authentically bitmasking, we'd only need to check that the result was positive. But since enums can be negative, even, strangely, when combined with the [Flags] attribute, it's defensive to code for != 0 rather than > 0.

Building off of @andnil's setup...

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace BitFlagPlay
{
    class Program
    {
        [Flags]
        public enum MyColor
        {
            Yellow = 0x01,
            Green = 0x02,
            Red = 0x04,
            Blue = 0x08
        }

        static void Main(string[] args)
        {
            var myColor = MyColor.Yellow | MyColor.Blue;
            var acceptableColors = MyColor.Yellow | MyColor.Red;

            Console.WriteLine((myColor & MyColor.Blue) != 0);     // True
            Console.WriteLine((myColor & MyColor.Red) != 0);      // False                
            Console.WriteLine((myColor & acceptableColors) != 0); // True
            // ... though only Yellow is shared.

            Console.WriteLine((myColor & MyColor.Green) != 0);    // Wait a minute... ;^D

            Console.Read();
        }
    }
}

You can open your command prompt as the intended user:

• Shift + Right Click on Command Prompt icon on task bar.
• Select (Run as differnt user)

• You will be prompted with login and password

• Once CommandP Prompt starts you can double check which user you are running as by the command whoami.

• Now you can change directory to your project and run

dotnet run

• In Visual Studio hit Ctrl+Alt+P (Attach to Process - can also be found from Debug menu)

• Make sure "Show Processes from All users" is checked.
• Find the running process and attach debugger.

You will need to kill the port by trying to use the following command on the terminal

$ sudo killall -9 nodejs

Below works fine.

//a[@id='oldcontent']

If you've tried certain ones and they haven't worked, then let us know, otherwise something simple like this should work.

This is a bit of an open ended question since screen sizes are changing all the time and what might have been correct two years ago would likely be out of date now.

I use Twitter Bootstrap 3 at present and it uses a fluid grid system designed to work at sizes ranging from mobile/very small all the way up to the huge wide screen monitors that are now available.

Currently the upper default in BS3 is 1200px which translates to a container width of 1144px after taking account of margins and padding of the grids elements.

In my experience, modern designers are working to a width of around 1366px for desktop. All recent designs I've been given to implement have been 1366px.

Note also that you can customise the BS3 grid quite heavily. For example we will use a 32 column grid with 4px gutter in our sites/designs going forwards.

Ultimately the decision on page width needs to be made based on your website analytics and the screen sizes that your visitors typically use.

I just built a few TimeSpan Extension methods. Thought I could share:

public static string ToReadableAgeString(this TimeSpan span)
{
    return string.Format("{0:0}", span.Days / 365.25);
}

public static string ToReadableString(this TimeSpan span)
{
    string formatted = string.Format("{0}{1}{2}{3}",
        span.Duration().Days > 0 ? string.Format("{0:0} day{1}, ", span.Days, span.Days == 1 ? string.Empty : "s") : string.Empty,
        span.Duration().Hours > 0 ? string.Format("{0:0} hour{1}, ", span.Hours, span.Hours == 1 ? string.Empty : "s") : string.Empty,
        span.Duration().Minutes > 0 ? string.Format("{0:0} minute{1}, ", span.Minutes, span.Minutes == 1 ? string.Empty : "s") : string.Empty,
        span.Duration().Seconds > 0 ? string.Format("{0:0} second{1}", span.Seconds, span.Seconds == 1 ? string.Empty : "s") : string.Empty);

    if (formatted.EndsWith(", ")) formatted = formatted.Substring(0, formatted.Length - 2);

    if (string.IsNullOrEmpty(formatted)) formatted = "0 seconds";

    return formatted;
}

If you are using Python 3 it might be because you are typing Tkinter not tkinter

IntelliJ IDEA and Android Studio were installed on my machine. I deleted IntelliJ IDEA because i have installed Dart and Flutter plugins on Android Studio. Then flutter doctor command works perfectly, maybe it is useful someone.

You can use viewtype to solve this problem, here is my demo: https://github.com/yefengfreedom/RecyclerViewWithHeaderFooterLoadingEmptyViewErrorView

1. you can define some recycler view display mode:

   public static final int MODE_DATA = 0, MODE_LOADING = 1, MODE_ERROR = 2, MODE_EMPTY = 3, MODE_HEADER_VIEW = 4, MODE_FOOTER_VIEW = 5;

2.override the getItemViewType mothod

 @Override
public int getItemViewType(int position) {
    if (mMode == RecyclerViewMode.MODE_LOADING) {
        return RecyclerViewMode.MODE_LOADING;
    }
    if (mMode == RecyclerViewMode.MODE_ERROR) {
        return RecyclerViewMode.MODE_ERROR;
    }
    if (mMode == RecyclerViewMode.MODE_EMPTY) {
        return RecyclerViewMode.MODE_EMPTY;
    }
    //check what type our position is, based on the assumption that the order is headers > items > footers
    if (position < mHeaders.size()) {
        return RecyclerViewMode.MODE_HEADER_VIEW;
    } else if (position >= mHeaders.size() + mData.size()) {
        return RecyclerViewMode.MODE_FOOTER_VIEW;
    }
    return RecyclerViewMode.MODE_DATA;
}

3.override the getItemCount method

@Override
public int getItemCount() {
    if (mMode == RecyclerViewMode.MODE_DATA) {
        return mData.size() + mHeaders.size() + mFooters.size();
    } else {
        return 1;
    }
}

4.override the onCreateViewHolder method. create view holder by viewType

@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    if (viewType == RecyclerViewMode.MODE_LOADING) {
        RecyclerView.ViewHolder loadingViewHolder = onCreateLoadingViewHolder(parent);
        loadingViewHolder.itemView.setLayoutParams(
                new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, parent.getHeight() - mToolBarHeight)
        );
        return loadingViewHolder;
    }
    if (viewType == RecyclerViewMode.MODE_ERROR) {
        RecyclerView.ViewHolder errorViewHolder = onCreateErrorViewHolder(parent);
        errorViewHolder.itemView.setLayoutParams(
                new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, parent.getHeight() - mToolBarHeight)
        );
        errorViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(final View v) {
                if (null != mOnErrorViewClickListener) {
                    new Handler().postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            mOnErrorViewClickListener.onErrorViewClick(v);
                        }
                    }, 200);
                }
            }
        });
        return errorViewHolder;
    }
    if (viewType == RecyclerViewMode.MODE_EMPTY) {
        RecyclerView.ViewHolder emptyViewHolder = onCreateEmptyViewHolder(parent);
        emptyViewHolder.itemView.setLayoutParams(
                new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, parent.getHeight() - mToolBarHeight)
        );
        emptyViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(final View v) {
                if (null != mOnEmptyViewClickListener) {
                    new Handler().postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            mOnEmptyViewClickListener.onEmptyViewClick(v);
                        }
                    }, 200);
                }
            }
        });
        return emptyViewHolder;
    }
    if (viewType == RecyclerViewMode.MODE_HEADER_VIEW) {
        RecyclerView.ViewHolder headerViewHolder = onCreateHeaderViewHolder(parent);
        headerViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(final View v) {
                if (null != mOnHeaderViewClickListener) {
                    new Handler().postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            mOnHeaderViewClickListener.onHeaderViewClick(v, v.getTag());
                        }
                    }, 200);
                }
            }
        });
        return headerViewHolder;
    }
    if (viewType == RecyclerViewMode.MODE_FOOTER_VIEW) {
        RecyclerView.ViewHolder footerViewHolder = onCreateFooterViewHolder(parent);
        footerViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(final View v) {
                if (null != mOnFooterViewClickListener) {
                    new Handler().postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            mOnFooterViewClickListener.onFooterViewClick(v, v.getTag());
                        }
                    }, 200);
                }
            }
        });
        return footerViewHolder;
    }
    RecyclerView.ViewHolder dataViewHolder = onCreateDataViewHolder(parent);
    dataViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(final View v) {
            if (null != mOnItemClickListener) {
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        mOnItemClickListener.onItemClick(v, v.getTag());
                    }
                }, 200);
            }
        }
    });
    dataViewHolder.itemView.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(final View v) {
            if (null != mOnItemLongClickListener) {
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        mOnItemLongClickListener.onItemLongClick(v, v.getTag());
                    }
                }, 200);
                return true;
            }
            return false;
        }
    });
    return dataViewHolder;
}

5.Override the onBindViewHolder method. bind data by viewType

@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
    if (mMode == RecyclerViewMode.MODE_LOADING) {
        onBindLoadingViewHolder(holder, position);
    } else if (mMode == RecyclerViewMode.MODE_ERROR) {
        onBindErrorViewHolder(holder, position);
    } else if (mMode == RecyclerViewMode.MODE_EMPTY) {
        onBindEmptyViewHolder(holder, position);
    } else {
        if (position < mHeaders.size()) {
            if (mHeaders.size() > 0) {
                onBindHeaderViewHolder(holder, position);
            }
        } else if (position >= mHeaders.size() + mData.size()) {
            if (mFooters.size() > 0) {
                onBindFooterViewHolder(holder, position - mHeaders.size() - mData.size());
            }
        } else {
            onBindDataViewHolder(holder, position - mHeaders.size());
        }
    }
}

I just tried all of these, and for IE11, the only thing that seems to work is disabled="true". Values of disabled or no value given didnt work. As a matter of fact, the jsp got an error that equal is required for all fields, so I had to specify disabled="true" for this to work.

Yes, you can merge them using HTML. When I create tables in .md files from Github, I always like to use HTML code instead of markdown.

Github Flavored Markdown supports basic HTML in .md file. So this would be the answer:

Markdown mixed with HTML:

| Tables        | Are           | Cool  |
| ------------- |:-------------:| -----:|
| col 3 is      | right-aligned | $1600 |
| col 2 is      | centered      |   $12 |
| zebra stripes | are neat      |    $1 |
| <ul><li>item1</li><li>item2</li></ul>| See the list | from the first column|

Or pure HTML:

<table>
  <tbody>
    <tr>
      <th>Tables</th>
      <th align="center">Are</th>
      <th align="right">Cool</th>
    </tr>
    <tr>
      <td>col 3 is</td>
      <td align="center">right-aligned</td>
      <td align="right">$1600</td>
    </tr>

This is how it looks on Github:

Assuming df has a unique index, this gives the row with the maximum value:

In [34]: df.loc[df['Value'].idxmax()]
Out[34]: 
Country        US
Place      Kansas
Value         894
Name: 7

Note that idxmax returns index labels. So if the DataFrame has duplicates in the index, the label may not uniquely identify the row, so df.loc may return more than one row.

Therefore, if df does not have a unique index, you must make the index unique before proceeding as above. Depending on the DataFrame, sometimes you can use stack or set_index to make the index unique. Or, you can simply reset the index (so the rows become renumbered, starting at 0):

df = df.reset_index()

Use try with resources. this will automatically close the resources.

try (BufferedReader br = new BufferedReader(new FileReader("C:/test.txt"))) {
    String line;
    while ((line = br.readLine()) != null) {
        System.out.println(line);
    }
} catch (Exception e) {

}

Python3:

import importlib.machinery

loader = importlib.machinery.SourceFileLoader('report', '/full/path/report/other_py_file.py')
handle = loader.load_module('report')

handle.mainFunction(parameter)

This method can be used to import whichever way you want in a folder structure (backwards, forwards doesn't really matter, i use absolute paths just to be sure).

There's also the more normal way of importing a python module in Python3,

import importlib
module = importlib.load_module('folder.filename')
module.function()

Kudos to Sebastian for spplying a similar answer for Python2:

import imp

foo = imp.load_source('module.name', '/path/to/file.py')
foo.MyClass()

For everyone with the problem

Error: Command '['/Users/me/Sites/site/venv3/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.

You have to install python3.6-venv

 sudo apt-get install python3.6-venv

All these suggestions work unless you put the anchors inside an UL list.

<ul>
    <li>
        <a>click me</a>>
    </li>
</ul>

Then any cascade style sheet rules are overridden in the Chrome browser. The width becomes auto. Then you must use inline CSS rules directly on the anchor itself.

I had this issue on resx files in my solution. I'm using Onedrive. However none of the above solutions fixed it.

The problem was the icon I used was in the MyWindow.resx files for the windows.

I removed that then grabbed the icon from the App Local Resources resource folder.

 private ResourceManager rm = App_LocalResources.LocalResources.ResourceManager;
 
 ..
 
InitializeComponent();
this.Icon = (Icon)rm.GetObject("IconName");

This happened after an update to VS2019.

This is a function that outputs one line per item, with indentation according to depth level. It is probably much more readable.

function GetDirs($path = $pwd, [Byte]$ToDepth = 255, [Byte]$CurrentDepth = 0)
{
    $CurrentDepth++
    If ($CurrentDepth -le $ToDepth) {
        foreach ($item in Get-ChildItem $path)
        {
            if (Test-Path $item.FullName -PathType Container)
            {
                "." * $CurrentDepth + $item.FullName
                GetDirs $item.FullName -ToDepth $ToDepth -CurrentDepth $CurrentDepth
            }
        }
    }
}

It is based on a blog post, Practical PowerShell: Pruning File Trees and Extending Cmdlets.

Since you are asking for space between , I would add an override to the last item to get rid of the extra margin there:

li {_x000D_
  background: red;_x000D_
  margin-bottom: 40px;_x000D_
}_x000D_
_x000D_
li:last-child {_x000D_
 margin-bottom: 0px;_x000D_
}_x000D_
_x000D_
ul {_x000D_
  background: silver;_x000D_
  padding: 1px;  _x000D_
  padding-left: 40px;_x000D_
}

<ul>_x000D_
<li>Item 1</li>_x000D_
<li>Item 1</li>_x000D_
<li>Item 1</li>_x000D_
<li>Item 1</li>_x000D_
<li>Item 1</li>_x000D_
</ul>

The result of it might not be visual at all times, because of margin-collapsing and stuff... in the example snippets I've included, I've added a small 1px padding to the ul-element to prevent the collapsing. Try removing the li:last-child-rule, and you'll see that the last item now extends the size of the ul-element.

Try this, loading data via ajax and displaying through return statement.

<script type="text/javascript">
function closeWindow(){

    var Data = $.ajax({
        type : "POST",
        url : "file.txt",  //loading a simple text file for sample.
        cache : false,
        global : false,
        async : false,
        success : function(data) {
            return data;
        }

    }).responseText;


    return "Are you sure you want to leave the page? You still have "+Data+" items in your shopping cart";
}

window.onbeforeunload = closeWindow;
</script>

Use -regex:

From the man page:

-regex pattern
       File name matches regular expression pattern.  This is a match on the whole path, not a search.  For example, to match a file named './fubar3',  you  can  use  the
       regular expression '.*bar.' or '.*b.*3', but not 'b.*r3'.

Also, I don't believe find supports regex extensions such as \d. You need to use [0-9].

find . -regex '.*test\.log\.[0-9][0-9][0-9][0-9]-[0-9][0-9]-[0-9][0-9]\.zip'

For anyone looking for a VB version of Adam's C# code written as an extension of the Control class:

''' <summary>Collects child controls of the specified type or base type within the passed control.</summary>
''' <typeparam name="T">The type of child controls to include. Restricted to objects of type Control.</typeparam>
''' <param name="Parent">Required. The parent form control.</param>
''' <returns>An object of type IEnumerable(Of T) containing the control collection.</returns>
''' <remarks>This method recursively calls itself passing child controls as the parent control.</remarks>
<Extension()>
Public Function [GetControls](Of T As Control)(
    ByVal Parent As Control) As IEnumerable(Of T)

    Dim oControls As IEnumerable(Of Control) = Parent.Controls.Cast(Of Control)()
    Return oControls.SelectMany(Function(c) GetControls(Of T)(c)).Concat(oControls.Where(Function(c) c.GetType() Is GetType(T) Or c.GetType().BaseType Is GetType(T))
End Function

NOTE: I've added BaseType matching for any derived custom controls. You can remove this or even make it an optional parameter if you wish.

Usage

Dim oButtons As IEnumerable(Of Button) = Me.GetControls(Of Button)()

Try:

SELECT strftime("%Y-%d-%m", col_name, 'unixepoch') AS col_name

It will format timestamp in milliseconds to yyyy-mm-dd string.

AFAIK GrantedAuthority and roles are same in spring security. GrantedAuthority's getAuthority() string is the role (as per default implementation SimpleGrantedAuthority).

For your case may be you can use Hierarchical Roles

<bean id="roleVoter" class="org.springframework.security.access.vote.RoleHierarchyVoter">
    <constructor-arg ref="roleHierarchy" />
</bean>
<bean id="roleHierarchy"
        class="org.springframework.security.access.hierarchicalroles.RoleHierarchyImpl">
    <property name="hierarchy">
        <value>
            ROLE_ADMIN > ROLE_createSubUsers
            ROLE_ADMIN > ROLE_deleteAccounts 
            ROLE_USER > ROLE_viewAccounts
        </value>
    </property>
</bean>

Not the exact sol you looking for, but hope it helps

Edit: Reply to your comment

Role is like a permission in spring-security. using intercept-url with hasRole provides a very fine grained control of what operation is allowed for which role/permission.

The way we handle in our application is, we define permission (i.e. role) for each operation (or rest url) for e.g. view_account, delete_account, add_account etc. Then we create logical profiles for each user like admin, guest_user, normal_user. The profiles are just logical grouping of permissions, independent of spring-security. When a new user is added, a profile is assigned to it (having all permissible permissions). Now when ever user try to perform some action, permission/role for that action is checked against user grantedAuthorities.

Also the defaultn RoleVoter uses prefix ROLE_, so any authority starting with ROLE_ is considered as role, you can change this default behavior by using a custom RolePrefix in role voter and using it in spring security.

"More NIO features" has file watch functionality, with implementation dependent upon the underlying OS. Should be in JDK7.

Update: Was added to Java SE 7. Chris Janicki offers a link to the relevant Java tutorial.

For every field that has choices set, the object will have a get_FOO_display() method, where FOO is the name of the field. This method returns the “human-readable” value of the field.

In Views

person = Person.objects.filter(to_be_listed=True)
context['gender'] = person.get_gender_display()

In Template

{{ person.get_gender_display }}

Documentation of get_FOO_display()

Just to give a short, working example to see an effect of their difference

new Thread(foo).Start();

private void foo()
{
  this.Dispatcher.BeginInvoke(DispatcherPriority.Normal,
    (ThreadStart)delegate()
    {
        myTextBox.Text = "bing";
        Thread.Sleep(TimeSpan.FromSeconds(3));
    });
  MessageBox.Show("done");
}

If use BeginInvoke, MessageBox pops simultaneous to the text update. If use Invoke, MessageBox pops after the 3 second sleep. Hence, showing the effect of an asynchronous (BeginInvoke) and a synchronous (Invoke) call.

Android has all the tools you need to parse json built-in. Example follows, no need for GSON or anything like that.

Get your JSON:

Assume you have a json string

String result = "{\"someKey\":\"someValue\"}";

Create a JSONObject:

JSONObject jObject = new JSONObject(result);

If your json string is an array, e.g.:

String result = "[{\"someKey\":\"someValue\"}]"

then you should use JSONArray as demonstrated below and not JSONObject

To get a specific string

String aJsonString = jObject.getString("STRINGNAME");

To get a specific boolean

boolean aJsonBoolean = jObject.getBoolean("BOOLEANNAME");

To get a specific integer

int aJsonInteger = jObject.getInt("INTEGERNAME");

To get a specific long

long aJsonLong = jObject.getLong("LONGNAME");

To get a specific double

double aJsonDouble = jObject.getDouble("DOUBLENAME");

To get a specific JSONArray:

JSONArray jArray = jObject.getJSONArray("ARRAYNAME");

To get the items from the array

for (int i=0; i < jArray.length(); i++)
{
    try {
        JSONObject oneObject = jArray.getJSONObject(i);
        // Pulling items from the array
        String oneObjectsItem = oneObject.getString("STRINGNAMEinTHEarray");
        String oneObjectsItem2 = oneObject.getString("anotherSTRINGNAMEINtheARRAY");
    } catch (JSONException e) {
        // Oops
    }
}

I've experienced the same problem and now I just found my solution to this issue.

#!/usr/bin/python

import sys
import os

os.system('meld "%s" "%s"' % (sys.argv[2], sys.argv[5]))

This is the code[1] for my case. When I tried this script I received error message like :

import: command not found

I found people talks about the shebang. As you see there is the shebang in my python code above. I tried these and those trials but didn't find a good solution.

I finally tried to type the shebang my self.

#!/usr/bin/python

and removed the copied one.

And my problem solved!!!

I copied the code from the internet[1].

And I guess there had been some unseeable(?) unseen special characters in the original copied shebang statement.

I use vim, sometimes I experience similar problems.. Especially when I copied some code snippet from the internet this kind of problems happen.. Web pages have some virus special characters!! I doubt. :-)

Journeyer

PS) I copied the code in Windows 7 - host OS - into the Windows clipboard and pasted it into my vim in Ubuntu - guest OS. VM is Oracle Virtual Machine.

You should define source code encoding, add this to the top of your script:

# -*- coding: utf-8 -*-

The reason why it works differently in console and in the IDE is, likely, because of different default encodings set. You can check it by running:

import sys
print sys.getdefaultencoding()

Also see:

• Why declare unicode by string in python?
• Changing default encoding of Python?

While creating the object for the progressbar check the following.

This fails:

dialog = new ProgressDialog(getApplicationContext());

While adding the activities context works..

dialog = new ProgressDialog(MainActivity.this);

Main()  {
    float rmvivek,arni,csc;
    char *c="1234.00";
    csc=atof(c);
    csc+=55;
    printf("the value is %f",csc);
}

Here is another example that return's a boolean value using try/catch.

private boolean doSomeThing(int index){
    try {
        if(index%2==0) 
            return true; 
    } catch (Exception e) {
        System.out.println(e.getMessage()); 
    }finally {
        System.out.println("Finally!!! ;) ");
    }
    return false; 
}

Since the question was asking how to do this with JS I'm providing a vanilla JS implementation.

var element = document.querySelector(".your-element-class-goes-here");
// it's a good idea to check whether the element exists
if (element != null && element != undefined) {
  element.disabled = "disabled";
}

Instead of invoking the sp_helptext locally with a remote argument, invoke it remotely with a local argument:

EXEC  [ServerName].[DatabaseName].dbo.sp_HelpText 'storedProcName'

I will try to explain you what this error is about.
Starting from MySQL 5.7.5, option ONLY_FULL_GROUP_BY is enabled by default.
Thus, according to standart SQL92 and earlier:

does not permit queries for which the select list, HAVING condition, or ORDER BY list refer to nonaggregated columns that are neither named in the GROUP BY clause nor are functionally dependent on (uniquely determined by) GROUP BY columns

(read more in docs)

So, for example:

SELECT * FROM `users` GROUP BY `name`;

You will get error message after executing query above.

#1055 - Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'testsite.user.id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

Why?
Because MySQL dont exactly understand, what certain values from grouped records to retrieve, and this is the point.

I.E. lets say you have this records in your users table:

And you will execute invalid query showen above.
And you will get error shown above, because, there is 3 records with name John, and it is nice, but, all of them have different email field values.
So, MySQL simply don't understand which of them to return in resulting grouped record.

You can fix this issue, by simply changing your query like this:

SELECT `name` FROM `users` GROUP BY `name`

Also, you may want to add more fields to SELECT section, but you cant do that, if they are not aggregated, but there is crutch you could use (but highly not reccomended):

SELECT ANY_VALUE(`id`), ANY_VALUE(`email`), `name` FROM `users` GROUP BY `name`

Now, you may ask, why using ANY_VALUE is highly not recommended?
Because MySQL don't exactly know what value of grouped records to retrieve, and by using this function, you asking it to fetch any of them (in this case, email of first record with name = John was fetched).
Exactly I cant come up with any ideas on why you would want this behaviour to exist.

Please, if you dont understand me, read more about how grouping in MySQL works, it is very simple.

And by the end, here is one more simple, yet valid query.
If you want to query total users count according to available ages, you may want to write down this query

SELECT `age`, COUNT(`age`) FROM `users` GROUP BY `age`;

Which is fully valid, according to MySQL rules.
And so on.

It is important to understand what exactly the problem is and only then write down the solution.

I've made a Python function where you enter the table and column to remove as arguments:

def removeColumn(table, column):
    columns = []
    for row in c.execute('PRAGMA table_info(' + table + ')'):
        columns.append(row[1])
    columns.remove(column)
    columns = str(columns)
    columns = columns.replace("[", "(")
    columns = columns.replace("]", ")")
    for i in ["\'", "(", ")"]:
        columns = columns.replace(i, "")
    c.execute('CREATE TABLE temptable AS SELECT ' + columns + ' FROM ' + table)
    c.execute('DROP TABLE ' + table)
    c.execute('ALTER TABLE temptable RENAME TO ' + table)
    conn.commit()

As per the info on Duda's and MeBigFatGuy's answers this won't work if there is a foreign key on the table, but this can be fixed with 2 lines of code (creating a new table and not just renaming the temporary table)

The problem is not that you can't forward-declare a template class. Yes, you do need to know all of the template parameters and their defaults to be able to forward-declare it correctly:

namespace std {
  template<class T, class Allocator = std::allocator<T>>
  class list;
}

But to make even such a forward declaration in namespace std is explicitly prohibited by the standard: the only thing you're allowed to put in std is a template specialisation, commonly std::less on a user-defined type. Someone else can cite the relevant text if necessary.

Just #include <list> and don't worry about it.

Oh, incidentally, any name containing double-underscores is reserved for use by the implementation, so you should use something like TEST_H instead of __TEST__. It's not going to generate a warning or an error, but if your program has a clash with an implementation-defined identifier, then it's not guaranteed to compile or run correctly: it's ill-formed. Also prohibited are names beginning with an underscore followed by a capital letter, among others. In general, don't start things with underscores unless you know what magic you're dealing with.

I encountered the same thing lately. it was just due to spaces when copying a script from a document to sql developer. I had to remove the spaces and the script ran.

Register your java class on Android manifest file

After that write this code on button click

startActivity(new intent(MainActivity.this,NextActivity.class));

That's an old thread, but in case you want to upload the image having same extension-

    $image = $request->image;
    $imageInfo = explode(";base64,", $image);
    $imgExt = str_replace('data:image/', '', $imageInfo[0]);      
    $image = str_replace(' ', '+', $imageInfo[1]);
    $imageName = "post-".time().".".$imgExt;
    Storage::disk('public_feeds')->put($imageName, base64_decode($image));

You can create 'public_feeds' in laravel's filesystem.php-

   'public_feeds' => [
        'driver' => 'local',
        'root'   => public_path() . '/uploads/feeds',
    ],

Edit

After getting feedback, It seems the original solution didn't work. That's why updated the answer as one of the suggestions.

def float_of_2_decimal(float_n) 
  float_n.to_d.round(2, :truncate).to_f
end

Other answers may work, if you want to have rounded numbers of 2 decimal places. But, If you want to have floating point numbers with first two decimal places without rounding, Those answers won't help.

So, to get a floating point number with first two decimal places, I used this technique. Doesn't work in some cases

def float_of_2_decimal(float_n)
  float_n.round(3).to_s[0..3].to_f
end

with 5.666666666666666666666666, it will return 5.66 instead of rounded 5.67. Hope it will help someone

It is probably of little help to you, but I enter that URL into Subclipse and the repository adds fine and I can browse and Show History on it.

Do you perhaps need to configure a proxy? You have to configure that in the Subversion runtime configuration area as Subclipse uses the Subversion libraries to connect to the server.

No. An object literal, as defined by MDC is:

a list of zero or more pairs of property names and associated values of an object, enclosed in curly braces ({}).

Therefore an object literal is not an array, and you can only access the properties using their explicit name or a for loop using the in keyword.

Text printed to stderr will show up in httpd's error log when running under mod_wsgi. You can either use print directly, or use logging instead.

Here is a one-liner that can be extended with grep to filter by name.

kubectl get pods -o jsonpath="{.items[*].metadata.name}" | \

I like to iterate backward using a for loop, but this can get tedious compared to foreach. One solution I like is to create an enumerator that traverses the list backward. You can implement this as an extension method on ArrayList or List<T>. The implementation for ArrayList is below.

    public static IEnumerable GetRemoveSafeEnumerator(this ArrayList list)
    {
        for (int i = list.Count - 1; i >= 0; i--)
        {
            // Reset the value of i if it is invalid.
            // This occurs when more than one item
            // is removed from the list during the enumeration.
            if (i >= list.Count)
            {
                if (list.Count == 0)
                    yield break;

                i = list.Count - 1;
            }

            yield return list[i];
        }
    }

The implementation for List<T> is similar.

    public static IEnumerable<T> GetRemoveSafeEnumerator<T>(this List<T> list)
    {
        for (int i = list.Count - 1; i >= 0; i--)
        {
            // Reset the value of i if it is invalid.
            // This occurs when more than one item
            // is removed from the list during the enumeration.
            if (i >= list.Count)
            {
                if (list.Count == 0)
                    yield break;

                i = list.Count - 1;
            }

            yield return list[i];
        }
    }

The example below uses the enumerator to remove all even integers from an ArrayList.

    ArrayList list = new ArrayList() {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};

    foreach (int item in list.GetRemoveSafeEnumerator())
    {
        if (item % 2 == 0)
            list.Remove(item);
    }

Use printf("%ld",a);

Have a look at format specifiers for printf

That's your jQuery API problem, not your script. There is not much to worry about.

Above answers are correct. This version is easy to follow:

Because "Schema export directory is not provided to the annotation processor", So we need to provide the directory for schema export:

Step [1] In your file which extends the RoomDatabase, change the line to:

`@Database(entities = ???.class,version = 1, exportSchema = true)`

Or

`@Database(entities = ???.class,version = 1)` 

(because the default value is always true)

Step [2] In your build.gradle(project:????) file, inside the defaultConfig{ } (which is inside android{ } big section), add the javaCompileOptions{ } section, it will be like:

         android{
                defaultConfig{
                      //javaComplieOptions SECTION
                      javaCompileOptions {
                            annotationProcessorOptions {
                                     arguments = ["room.schemaLocation":"$projectDir/schemas".toString()]
                            }
                       }
                      //Other SECTION
                      ...
                }
         }

$projectDir:is a variable name, you cannot change it. it will get your own project directory

schemas:is a string, you can change it to any you like. For example: "$projectDir/MyOwnSchemas".toString()

My problem solved with these :

1- Add this to your head :

<base href="/" />

2- Use this in app.config

$locationProvider.html5Mode(true);

As was already pointed out in the comment, the MAC address can be received via the WifiManager.

WifiManager manager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiInfo info = manager.getConnectionInfo();
String address = info.getMacAddress();

Also do not forget to add the appropriate permissions into your AndroidManifest.xml

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

Please refer to Android 6.0 Changes.

To provide users with greater data protection, starting in this release, Android removes programmatic access to the device’s local hardware identifier for apps using the Wi-Fi and Bluetooth APIs. The WifiInfo.getMacAddress() and the BluetoothAdapter.getAddress() methods now return a constant value of 02:00:00:00:00:00.

To access the hardware identifiers of nearby external devices via Bluetooth and Wi-Fi scans, your app must now have the ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION permissions.

If the HTTP Connection doesn't timeout, You can implement the timeout checker in the background thread itself (AsyncTask, Service, etc), the following class is an example for Customize AsyncTask which timeout after certain period

One can access the "Find in Files" window via the drop-down menu selection and search all files in the Entire Solution: Edit > Find and Replace > Find in Files

Other, alternative is to open the "Find in Files" window via the "Standard Toolbars" button as highlighted in the below screen-short:

Raising ActionController::RoutingError('not found') has always felt a little bit strange to me - in the case of an unauthenticated user, this error does not reflect reality - the route was found, the user is just not authenticated.

I happened across config.action_dispatch.rescue_responses and I think in some cases this is a more elegant solution to the stated problem:

# application.rb
config.action_dispatch.rescue_responses = {
  'UnauthenticatedError' => :not_found
}

# my_controller.rb
before_action :verify_user_authentication

def verify_user_authentication
  raise UnauthenticatedError if !user_authenticated?
end

What's nice about this approach is:

1. It hooks into the existing error handling middleware like a normal ActionController::RoutingError, but you get a more meaningful error message in dev environments
2. It will correctly set the status to whatever you specify in the rescue_responses hash (in this case 404 - not_found)
3. You don't have to write a not_found method that needs to be available everywhere.

I am using CDN for my project and as part of fallback handling, i was using below code,

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
    <script type="text/javascript">
                if ((typeof jQuery == 'undefined')) {
                    document.write(unescape("%3Cscript src='/Responsive/Scripts/jquery-1.9.1.min.js' type='text/javascript'%3E%3C/script%3E"));   
                }
</script>

Just to verify, i removed CDN reference and execute the code. Its broken and it's never entered into if loop as typeof jQuery is coming as function instead of undefined .

This is because of cached older version of jquery 1.6.1 which return function and break my code because i am using jquery 1.9.1. As i need exact version of jquery, i modified code as below,

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type="text/javascript">
            if ((typeof jQuery == 'undefined') || (jQuery.fn.jquery != "1.9.1")) {
                document.write(unescape("%3Cscript src='/Responsive/Scripts/jquery-1.9.1.min.js' type='text/javascript'%3E%3C/script%3E"));   
            }
</script>

Create the hash:

hash = {:item1 => 1}

Add a new item to it:

hash[:item2] = 2

Here is another choice: Chaosreader

So I need to debug an application which posts xml to a 3rd party application. I found a brilliant little perl script which does all the hard work – you just chuck it a tcpdump output file, and it does all the manipulation and outputs everything you need...

The script is called chaosreader0.94. See http://www.darknet.org.uk/2007/11/chaosreader-trace-tcpudp-sessions-from-tcpdump/

It worked like a treat, I did the following:

tcpdump host www.blah.com -s 9000 -w outputfile; perl chaosreader0.94 outputfile

Make sure that you are building your web app as "Any CPU". Right click your web project --> Properties --> Build --> and look for the "Platform Target". Choose "Any CPU" or play around with it.

Hope this helps!

Codecs proper:

ffmpeg -codecs

Formats:

ffmpeg -formats

You have to import the font in your stylesheet like this:

@font-face{
    font-family: "Thonburi-Bold";
    src: url('Thonburi-Bold.ttf'),
    url('Thonburi-Bold.eot'); /* IE */
}

Lets say your HTML looks something like this:

<div class="box">
    <!-- stuff -->
    <p class="bet_time">Bet 5 days ago</p>
</div>

Then, with CSS, you can make that text appear in the bottom right like so:

.box {
    position:relative;
}
.bet_time {
    position:absolute;
    bottom:0;
    right:0;
}

The way this works is that absolutely positioned elements are always positioned with respect to the first relatively positioned parent element, or the window. Because we set the box's position to relative, .bet_time positions its right edge to the right edge of .box and its bottom edge to the bottom edge of .box

Use conda init

As pointed out in a different answer, manually adding Conda on $PATH is no longer recommended as of v4.4.0 (see Release Notes). Furthermore, since Conda v4.6 new functionality to manage shell initialization via the conda init command was introduced. Hence, the updated recommendation is to run

Linux/UNIX (OS X < 10.15)

./anaconda3/bin/conda init

Mac OS X >= 10.15

./anaconda3/bin/conda init zsh

Windows

./anaconda3/Scripts/conda.exe init

You must launch a new shell or source your init file (e.g., source .bashrc) for the changes to take effect.

Alternative shells

You may need to explicitly identify your shell to Conda. For example, if you run zsh (Mac OS X 10.15+ default) instead of bash then you would run

./anaconda3/bin/conda init zsh

Please see ./anaconda3/bin/conda init --help for a comprehensive list of supported shells.

Word of Caution

I'd recommend running the above command with a --dry-run|-d flag and a verbosity (-vv) flag, in order to see exactly what it would do. If you don't already have a Conda-managed section in your shell run commands file (e.g., .bashrc), then this should appear like a straight-forward insertion of some new lines. If it isn't such a straightforward insertion, I'd recommend clearing any previous Conda sections from $PATH and the relevant shell initialization files (e.g., bashrc) first.

Potential Automated Cleanup

Conda v4.6.9 introduced a --reverse flag that automates removing the changes that are inserted by conda init.

You can use the ThenBy and ThenByDescending extension methods:

foobarList.OrderBy(x => x.Foo).ThenBy( x => x.Bar)

I'd recommend the following solution.

It prints the env vars you didn't include, which lets you add them all at once. If you go for the for loop, you're going to have to rerun the program to see each missing var.

from os import environ

REQUIRED_ENV_VARS = {"A", "B", "C", "D"}
diff = REQUIRED_ENV_VARS.difference(environ)
if len(diff) > 0:
    raise EnvironmentError(f'Failed because {diff} are not set')

I have only tested with EditText but you can use the method

public void setBackgroundResource (int resid)

to apply a style defined in an XML file.

Sine this method belongs to View I believe it will work with any UI element.

regards.

Use find. Seriously, it is the best way because then you can really see what files it's operating on:

find . -name "*.sql" -exec grep -H "slow" {} \;

Note, the -H is mac-specific, it shows the filename in the results.

INADDR_ANY is used when you don't need to bind a socket to a specific IP. When you use this value as the address when calling bind(), the socket accepts connections to all the IPs of the machine.

I found the easy way

--- right click the webconfig or app config file and click EDIT WCF CONFIGURATION and got to bingdigs ans select yore service and right side show maxReciveMessageSize give a large number ---

Use BigDecimal:

new BigDecimal(theInputString);

It retains all decimal digits. And you are sure of the exact representation since it uses decimal base, not binary base, to store the precision/scale/etc.

And it is not subject to precision loss like float or double are, unless you explicitly ask it to.

How do I create a new column with Groupby().Sum()?

There are two ways - one straightforward and the other slightly more interesting.

Everybody's Favorite: GroupBy.transform() with 'sum'

@Ed Chum's answer can be simplified, a bit. Call DataFrame.groupby rather than Series.groupby. This results in simpler syntax.

# The setup.
df[['Date', 'Data3']]

         Date  Data3
0  2015-05-08      5
1  2015-05-07      8
2  2015-05-06      6
3  2015-05-05      1
4  2015-05-08     50
5  2015-05-07    100
6  2015-05-06     60
7  2015-05-05    120

df.groupby('Date')['Data3'].transform('sum')

0     55
1    108
2     66
3    121
4     55
5    108
6     66
7    121
Name: Data3, dtype: int64 

It's a tad faster,

df2 = pd.concat([df] * 12345)

%timeit df2['Data3'].groupby(df['Date']).transform('sum')
%timeit df2.groupby('Date')['Data3'].transform('sum')

10.4 ms ± 367 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
8.58 ms ± 559 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

Unconventional, but Worth your Consideration: GroupBy.sum() + Series.map()

I stumbled upon an interesting idiosyncrasy in the API. From what I tell, you can reproduce this on any major version over 0.20 (I tested this on 0.23 and 0.24). It seems like you consistently can shave off a few milliseconds of the time taken by transform if you instead use a direct function of GroupBy and broadcast it using map:

df.Date.map(df.groupby('Date')['Data3'].sum())

0     55
1    108
2     66
3    121
4     55
5    108
6     66
7    121
Name: Date, dtype: int64

Compare with

df.groupby('Date')['Data3'].transform('sum')

0     55
1    108
2     66
3    121
4     55
5    108
6     66
7    121
Name: Data3, dtype: int64

My tests show that map is a bit faster if you can afford to use the direct GroupBy function (such as mean, min, max, first, etc). It is more or less faster for most general situations upto around ~200 thousand records. After that, the performance really depends on the data.

(Left: v0.23, Right: v0.24)

Nice alternative to know, and better if you have smaller frames with smaller numbers of groups. . . but I would recommend transform as a first choice. Thought this was worth sharing anyway.

Benchmarking code, for reference:

import perfplot

perfplot.show(
    setup=lambda n: pd.DataFrame({'A': np.random.choice(n//10, n), 'B': np.ones(n)}),
    kernels=[
        lambda df: df.groupby('A')['B'].transform('sum'),
        lambda df:  df.A.map(df.groupby('A')['B'].sum()),
    ],
    labels=['GroupBy.transform', 'GroupBy.sum + map'],
    n_range=[2**k for k in range(5, 20)],
    xlabel='N',
    logy=True,
    logx=True
)

To write it with a while loop you can do:

ls -f /var | while read -r file; do cmd $file; done

The primary disadvantage of this is that cmd is run in a subshell, which causes some difficulty if you are trying to set variables. The main advantages are that the shell does not need to load all of the filenames into memory, and there is no globbing. When you have a lot of files in the directory, those advantages are important (that's why I use -f on ls; in a large directory ls itself can take several tens of seconds to run and -f speeds that up appreciably. In such cases 'for file in /var/*' will likely fail with a glob error.)

intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

This will get you to a previous activity keeping its stack and clearing all activities after it from the stack.

For example, if stack was A->B->C->D and you start B with this flag, stack will be A->B

try:

[checked]="item.checked"

For Angular 8 or posterior @ViewChild have an additional parameter called opts, which have two properties: read and static, read is optional. You can use it like so:

// ...
@ViewChild('mydiv', { static: false }) public mydiv: ElementRef;

constructor() {
// ...

<div #mydiv></div>

NOTE: Static: false is not required anymore in Angular 9. (just { static: true } when you are going to use that variable inside ngOnInit)

Use GET method if you want to retrieve the resources from URL. You could always see the last page if you hit the back button of your browser, and it could be bookmarked, so it is not as secure as POST method.

Use POST method if you want to 'submit' something to the URL. For example you want to create a google account and you may need to fill in all the detailed information, then you hit 'submit' button (POST method is called here), once you submit successfully, and try to hit back button of your browser, you will get error or a new blank form, instead of last page with filled form.

Additionally, if you want to use the filter in your controller the same way you do it here:

<div ng-repeat="item in items | filter:criteriaMatch(criteria)">
  {{ item }}
</div>

You could do something like:

var filteredItems =  $scope.$eval('items | filter:filter:criteriaMatch(criteria)');

If you want to move the position of the legend please use the following code:

library(reshape2) # for melt
df <- melt(outer(1:4, 1:4), varnames = c("X1", "X2"))
p1 <- ggplot(df, aes(X1, X2)) + geom_tile(aes(fill = value))
p1 + scale_fill_continuous(guide = guide_legend()) +
    theme(legend.position="bottom")

This should give you the desired result.

http://fiji.sc/Uber-JAR provides an excellent explanation of the alternatives:

There are three common methods for constructing an uber-JAR:

1. Unshaded. Unpack all JAR files, then repack them into a single JAR.
   • Pro: Works with Java's default class loader.
   • Con: Files present in multiple JAR files with the same path (e.g., META-INF/services/javax.script.ScriptEngineFactory) will overwrite one another, resulting in faulty behavior.
   • Tools: Maven Assembly Plugin, Classworlds Uberjar
2. Shaded. Same as unshaded, but rename (i.e., "shade") all packages of all dependencies.
   • Pro: Works with Java's default class loader. Avoids some (not all) dependency version clashes.
   • Con: Files present in multiple JAR files with the same path (e.g., META-INF/services/javax.script.ScriptEngineFactory) will overwrite one another, resulting in faulty behavior.
   • Tools: Maven Shade Plugin
3. JAR of JARs. The final JAR file contains the other JAR files embedded within.
   • Pro: Avoids dependency version clashes. All resource files are preserved.
   • Con: Needs to bundle a special "bootstrap" classloader to enable Java to load classes from the wrapped JAR files. Debugging class loader issues becomes more complex.
   • Tools: Eclipse JAR File Exporter, One-JAR.

Here is a simple program that displays the camera feed in a cv2.namedWindow and will take a snapshot when you hit SPACE. It will also quit if you hit ESC.

import cv2

cam = cv2.VideoCapture(0)

cv2.namedWindow("test")

img_counter = 0

while True:
    ret, frame = cam.read()
    if not ret:
        print("failed to grab frame")
        break
    cv2.imshow("test", frame)

    k = cv2.waitKey(1)
    if k%256 == 27:
        # ESC pressed
        print("Escape hit, closing...")
        break
    elif k%256 == 32:
        # SPACE pressed
        img_name = "opencv_frame_{}.png".format(img_counter)
        cv2.imwrite(img_name, frame)
        print("{} written!".format(img_name))
        img_counter += 1

cam.release()

cv2.destroyAllWindows()

I think this should answer your question for the most part. If there is any line of it that you don't understand let me know and I'll add comments.

If you need to grab multiple images per press of the SPACE key, you will need an inner loop or perhaps just make a function that grabs a certain number of images.

Note that the key events are from the cv2.namedWindow so it has to have focus.

I use ruamel.yaml. Details & debate here.

from ruamel import yaml

with open(filename, 'r') as fp:
    read_data = yaml.load(fp)

Usage of ruamel.yaml is compatible (with some simple solvable problems) with old usages of PyYAML and as it is stated in link I provided, use

from ruamel import yaml

instead of

import yaml

and it will fix most of your problems.

EDIT: PyYAML is not dead as it turns out, it's just maintained in a different place.

Just to add on awesomo's answer, you can also add that line into your ~/.bash_profile or ~/.profile

You can try this:

select
  count(distinct tag) as tag_count,
  count(distinct (case when entryId > 0 then tag end)) as positive_tag_count
from
  your_table_name;

The first count(distinct...) is easy. The second one, looks somewhat complex, is actually the same as the first one, except that you use case...when clause. In the case...when clause, you filter only positive values. Zeros or negative values would be evaluated as null and won't be included in count.

One thing to note here is that this can be done by reading the table once. When it seems that you have to read the same table twice or more, it can actually be done by reading once, in most of the time. As a result, it will finish the task a lot faster with less I/O.

ran across this page and several like it all talking about the GIT_DISCOVERY_ACROSS_FILESYSTEM not set message. In my case our sys admin had decided that the apache2 directory needed to be on a mounted filesystem in case the disk for the server stopped working and had to get rebuilt. I found this with a simple df command:

-->  UBIk  <--:root@ns1:[/etc]
--PRODUCTION--(16:48:43)--> df -h
Filesystem                           Size  Used Avail Use% Mounted on
<snip>
/dev/mapper/vgraid-lvapache           63G   54M   60G   1% /etc/apache2
<snip>

To fix this I just put the following in the root user's shell (as they are the only ones who need to be looking at etckeeper revisions:

export GIT_DISCOVERY_ACROSS_FILESYSTEM=1

and all was well and good...much joy.

As an update to the OP's question, I can confirm that the timepicker found at http://jdewit.github.io/bootstrap-timepicker/ does in fact work with Bootstrap 3 now with no problems at all.

CSS Only:

Thinking about it on my way to the supermarket, you could of course also skip the entire image map idea, and make use of :hover on the elements on top of the image (changed the divs to a-blocks). Which makes things hell of a lot simpler, no jQuery needed...

Short explanation:

• Image is in the bottom
• 2 x a with display:block and absolute positioning + opacity:0
• Set opacity to 0.2 on hover

Example:

.area {_x000D_
    background:#fff;_x000D_
    display:block;_x000D_
    height:475px;_x000D_
    opacity:0;_x000D_
    position:absolute;_x000D_
    width:320px;_x000D_
}_x000D_
#area2 {_x000D_
    left:320px;_x000D_
}_x000D_
#area1:hover, #area2:hover {_x000D_
    opacity:0.2;_x000D_
}

<a id="area1" class="area" href="#"></a>_x000D_
<a id="area2" class="area" href="#"></a>_x000D_

Original Answer using jQuery

I just created something similar with jQuery, I don't think it can be done with CSS only.

Short explanation:

• Image is in the bottom
• Divs with rollover (image or color) with absolute positioning + display:none
• Transparent gif with the actual #map is on top (absolute position) (to prevent call to mouseout when the rollovers appear)
• jQuery is used to show/hide the divs

    $(document).ready(function() {_x000D_
        if($('#location-map')) {_x000D_
            $('#location-map area').each(function() {_x000D_
                var id = $(this).attr('id');_x000D_
                $(this).mouseover(function() {_x000D_
                    $('#overlay'+id).show();_x000D_
                    _x000D_
                });_x000D_
                _x000D_
                $(this).mouseout(function() {_x000D_
                    var id = $(this).attr('id');_x000D_
                    $('#overlay'+id).hide();_x000D_
                });_x000D_

Hope it helps..

You have to manually copy each key/value pair to a new map. This is a loop that people have to reprogram any time they want a deep copy of a map.

You can automatically generate the function for this by installing mapper from the maps package using

go get -u github.com/drgrib/maps/cmd/mapper

and running

mapper -types string:aStruct

which will generate the file map_float_astruct.go containing not only a (deep) Copy for your map but also other "missing" map functions ContainsKey, ContainsValue, GetKeys, and GetValues:

func ContainsKeyStringAStruct(m map[string]aStruct, k string) bool {
    _, ok := m[k]
    return ok
}

func ContainsValueStringAStruct(m map[string]aStruct, v aStruct) bool {
    for _, mValue := range m {
        if mValue == v {
            return true
        }
    }

    return false
}

func GetKeysStringAStruct(m map[string]aStruct) []string {
    keys := []string{}

    for k, _ := range m {
        keys = append(keys, k)
    }

    return keys
}

func GetValuesStringAStruct(m map[string]aStruct) []aStruct {
    values := []aStruct{}

    for _, v := range m {
        values = append(values, v)
    }

    return values
}

func CopyStringAStruct(m map[string]aStruct) map[string]aStruct {
    copyMap := map[string]aStruct{}

    for k, v := range m {
        copyMap[k] = v
    }

    return copyMap
}

Full disclosure: I am the creator of this tool. I created it and its containing package because I found myself constantly rewriting these algorithms for the Go map for different type combinations.

The best way I can think of to accomplish this is via sp_addlinkedserver. You need to make sure that whatever account you use to add the link (via sp_addlinkedsrvlogin) has permissions to the table you're joining, but then once the link is established, you can call the server by name, i.e.:

SELECT *
FROM server1table
    INNER JOIN server2.database.dbo.server2table ON .....

The data-* attributes is used to store custom data private to the page or application

So Bootstrap uses these attributes for saving states of objects

W3School data-* description

To grant a permission:

grant select on schema_name.sequence_name to user_or_role_name;

To check which permissions have been granted

select * from all_tab_privs where TABLE_NAME = 'sequence_name'

Okay if you've created the core dump with gcore or gdb then you'll need to convert it to something called a HPROF file. These can be used by VisualVM, Netbeans or Eclipse's Memory Analyzer Tool (formerly SAP Memory Analyzer). I'd recommend Eclipse MAT.

To convert the file use the commandline tool jmap.

# jmap -dump:format=b,file=dump.hprof /usr/bin/java core.1234

where:

dump.hprof is the name of the hprof file you wish to create

/usr/bin/java is the path to the version of the java binary that generated the core dump

core.1234 is your regular core file.

I don't know why but animating only the visibility property is not working on any browser.

What you can do is animate the opacity property in such a way that the browser doesn't have enough frames to fade in or out the text.

Example:

span {_x000D_
  opacity: 0;_x000D_
  animation: blinking 1s linear infinite;_x000D_
}_x000D_
_x000D_
@keyframes blinking {_x000D_
  from,_x000D_
  49.9% {_x000D_
    opacity: 0;_x000D_
  }_x000D_
  50%,_x000D_
  to {_x000D_
    opacity: 1;_x000D_
  }_x000D_
}

<span>I'm blinking text</span>

See jQuery.scroll(). You can bind this to the window element to get your desired event hook.

On scroll, then simply check your scroll position:

$(window).scroll(function() {
  var scrollTop = $(window).scrollTop();
  if ( scrollTop > $(headerElem).offset().top ) { 
    // display add
  }
});

I tried sudo apt install nginx-full. You will get all the required packages.

SQL Server Express editions are limited in some ways - one way is that they don't have the SQL Agent that allows you to schedule jobs.

There are a few third-party extensions that provide that capability - check out e.g.:

• Express Agent for SQL Server Express: Jobs, Jobs, Jobs and Mail (latest update is from 2005, it isn't maintained anymore).
• SQL Scheduler

Try this:

.circle {
    height: 20px;
    width: 20px;
    padding: 5px;
    text-align: center; 
    border-radius: 50%;
    display: inline-block;
    color:#fff;
    font-size:1.1em;
    font-weight:600;
    background-color: rgba(0,0,0,0.1);
    border: 1px solid rgba(0,0,0,0.2);
}

New in Django 1.5, now you can create your own Custom User Model (which seems to be good thing to do in above case). Refer to 'Customizing authentication in Django'

Probably the coolest new feature on 1.5 release.

Parameters in the URL are GET parameters, a request body, if present, is POST data. So your basic premise is by definition not achievable.

You should choose whether to use POST or GET based on the action. Any destructive action, i.e. something that permanently changes the state of the server (deleting, adding, editing) should always be invoked by POST requests. Any pure "information retrieval" should be accessible via an unchanging URL (i.e. GET requests).

To make a POST request, you need to create a <form>. You could use Javascript to create a POST request instead, but I wouldn't recommend using Javascript for something so basic. If you want your submit button to look like a link, I'd suggest you create a normal form with a normal submit button, then use CSS to restyle the button and/or use Javascript to replace the button with a link that submits the form using Javascript (depending on what reproduces the desired behavior better). That'd be a good example of progressive enhancement.

Yes, mysql_fetch_array() only returns one result. If you want to retrieve more than one row, you need to put the function call in a while loop.

Two examples:

This will only return the first row

$row = mysql_fetch_array($result);

This will return one row on each loop, until no more rows are available from the result set

while($row = mysql_fetch_array($result))
{
    //Do stuff with contents of $row
}

printf("%.*s\n",n,(char *) memset(buffer,c,n));

n <= sizeof(buffer) [ maybe also n < 2^16]

However the optimizer may change it to puts(buffer) and then the lack of EoS will .....

And the assumption is that memset is an assembler instruction (but still a loop be it on chip).

Strictly seen there is no solution given you precondition 'No loop'.

I don't think you can do it in a single statement. Better do:

if (!obj.isPresent()) {
    logger.fatal(...);   
} else {
    obj.get().setAvailable(true);
}
return obj;
