Write it like this:

String CmbTitle = (cmb.SelectedItem as ComboBoxItem).Content.ToString()

Use path.join(__dirname, '/start.html');

var fs = require('fs'),
    path = require('path'),    
    filePath = path.join(__dirname, 'start.html');

fs.readFile(filePath, {encoding: 'utf-8'}, function(err,data){
    if (!err) {
        console.log('received data: ' + data);
        response.writeHead(200, {'Content-Type': 'text/html'});
        response.write(data);
        response.end();
    } else {
        console.log(err);
    }
});

If you want it casted to a specific type you can use this method. Most non primitive types won't by default support direct casting so you will have to handle those accordingly.

  public T GetValue<T>(string registryKeyPath, string value, T defaultValue = default(T))
  {
    T retVal = default(T);

      retVal = (T)Registry.GetValue(registryKeyPath, value, defaultValue);

      return retVal;
  }

@CMS's answer is just fine, but I want to note that you can use this package: https://github.com/sindresorhus/slugify, which does it for you and covers many edge cases (i.e., German umlauts, Vietnamese, Arabic, Russian, Romanian, Turkish, etc.).

Python 3.9 adds the zoneinfo module so now only the the standard library is needed!

>>> from zoneinfo import ZoneInfo
>>> from datetime import datetime

>>> d = datetime(2020, 10, 31, 12, tzinfo=ZoneInfo('America/Los_Angeles'))
>>> d.astimezone(ZoneInfo('Europe/Berlin'))  # 12:00 in Cali will be 20:00 in Berlin
datetime.datetime(2020, 10, 31, 20, 0, tzinfo=zoneinfo.ZoneInfo(key='Europe/Berlin'))

Wikipedia list of available time zones

Some functions such as now() and utcnow() return timezone-unaware datetimes, meaning they contain no timezone information. I recommend only requesting timezone-aware values from them using the keyword tz=ZoneInfo('localtime').

If astimezone gets a timezone-unaware input, it will assume it is local time, which can lead to errors:

>>> datetime.utcnow()  # UTC -- NOT timezone-aware!!
datetime.datetime(2020, 6, 1, 22, 39, 57, 376479)
>>> datetime.now()     # Local time -- NOT timezone-aware!!
datetime.datetime(2020, 6, 2, 0, 39, 57, 376675)

>>> datetime.now(tz=ZoneInfo('localtime'))  # timezone-aware
datetime.datetime(2020, 6, 2, 0, 39, 57, 376806, tzinfo=zoneinfo.ZoneInfo(key='localtime'))
>>> datetime.now(tz=ZoneInfo('Europe/Berlin'))  # timezone-aware
datetime.datetime(2020, 6, 2, 0, 39, 57, 376937, tzinfo=zoneinfo.ZoneInfo(key='Europe/Berlin'))
>>> datetime.utcnow().astimezone(ZoneInfo('Europe/Berlin'))  # WRONG!!
datetime.datetime(2020, 6, 1, 22, 39, 57, 377562, tzinfo=zoneinfo.ZoneInfo(key='Europe/Berlin'))

Windows has no system time zone database, so here an extra package is needed:

pip install tzdata  

There is a backport to allow use in Python 3.6 to 3.8:

sudo pip install backports.zoneinfo

Then:

from backports.zoneinfo import ZoneInfo

Right click on the breakpoint works fine for me (though mostly I am using it for conditional breakpoints on specific variable values. Even breaking on expressions involving a thread name works which is very useful if you're trying to spot threading issues).

datetime.datetime.fromtimestamp() is correct, except you are probably having timestamp in miliseconds (like in JavaScript), but fromtimestamp() expects Unix timestamp, in seconds.

Do it like that:

>>> import datetime
>>> your_timestamp = 1331856000000
>>> date = datetime.datetime.fromtimestamp(your_timestamp / 1e3)

and the result is:

>>> date
datetime.datetime(2012, 3, 16, 1, 0)

Does it answer your question?

EDIT: J.F. Sebastian correctly suggested to use true division by 1e3 (float 1000). The difference is significant, if you would like to get precise results, thus I changed my answer. The difference results from the default behaviour of Python 2.x, which always returns int when dividing (using / operator) int by int (this is called floor division). By replacing the divisor 1000 (being an int) with the 1e3 divisor (being representation of 1000 as float) or with float(1000) (or 1000. etc.), the division becomes true division. Python 2.x returns float when dividing int by float, float by int, float by float etc. And when there is some fractional part in the timestamp passed to fromtimestamp() method, this method's result also contains information about that fractional part (as the number of microseconds).

If you want everyone to be able to access the Node app, then try using

res.header('Access-Control-Allow-Origin', "*")

That will allow requests from any origin. The CORS enable site has a lot of information on the different Access-Control-Allow headers and how to use them.

I you are using Chrome, please look at this bug bug regarding localhost and Access-Control-Allow-Origin. There is another StackOverflow question here that details the issue.

You can use LINQ to XML,

XDocument doc = XDocument.Load(file);

var result = (from ele in doc.Descendants("section")
              select ele).ToList();

foreach (var t in result)
{
    if (t.Attributes("split").Count() != 0)
    {
        // Exist
    }

    // Suggestion from @UrbanEsc
    if(t.Attributes("split").Any())
    {

    }
}

OR

 XDocument doc = XDocument.Load(file);

 var result = (from ele in doc.Descendants("section").Attributes("split")
               select ele).ToList();

 foreach (var t in result)
 {
     // Response.Write("<br/>" +  t.Value);
 }

There are a number of properties on the StringComparer static class that return comparers for any type of case-sensitivity you might want:

StringComparer Properties

For instance, you can call

StringComparer.CurrentCultureIgnoreCase.Equals(string1, string2)

or

StringComparer.CurrentCultureIgnoreCase.Compare(string1, string2)

It's a bit cleaner than the string.Equals or string.Compare overloads that take a StringComparison argument.

You can also use it

export function diffDateAndToString(small: Date, big: Date) {


    // To calculate the time difference of two dates 
    const Difference_In_Time = big.getTime() - small.getTime()

    // To calculate the no. of days between two dates 
    const Days = Difference_In_Time / (1000 * 3600 * 24)
    const Mins = Difference_In_Time / (60 * 1000)
    const Hours = Mins / 60

    const diffDate = new Date(Difference_In_Time)

    console.log({ date: small, now: big, diffDate, Difference_In_Days: Days, Difference_In_Mins: Mins, Difference_In_Hours: Hours })

    var result = ''

    if (Mins < 60) {
        result = Mins + 'm'
    } else if (Hours < 24) result = diffDate.getMinutes() + 'h'
    else result = Days + 'd'
    return { result, Days, Mins, Hours }
}

results in { result: '30d', Days: 30, Mins: 43200, Hours: 720 }

I had the "No module named PyQt4.QtCore" error and installing the python-qt4 package fixed it only partially: I could run

from PyQt4.QtCore import SIGNAL

from a python interpreter but only without activating my virtualenv.

The only solution I've found till now to use a virtualenv is to copy the PyQt4 folder and the sip.so file into my virtualenv as explained here: Is it possible to add PyQt4/PySide packages on a Virtualenv sandbox?

Works fine for me with this

    Calendar cal = Calendar.getInstance(TimeZone.getTimeZone());
    cal.set(Calendar.MONTH, month-1);  
    cal.set(Calendar.YEAR, year);  
    cal.add(Calendar.DATE, -1);  
    cal.set(Calendar.DAY_OF_MONTH, 
    cal.getActualMaximum(Calendar.DAY_OF_MONTH));
    cal.set(Calendar.HOUR_OF_DAY, 0);
    cal.set(Calendar.MINUTE, 0);
    cal.set(Calendar.SECOND, 0);
    cal.set(Calendar.MILLISECOND, 0);
    return cal.getTimeInMillis();

I ended up doing something like this for AngularJS in case someone stumbles across this question:

const imageElem = angular.element('#awardImg');

if (imageElem[0].files[0])
    vm.award.imageElem = imageElem;
    vm.award.image = imageElem[0].files[0];

And then:

if (vm.award.imageElem)
    $('#awardImg').replaceWith(vm.award.imageElem);
    delete vm.award.imageElem;

RGB values fall nicely on bit boundaries; decimal digits don't. I don't think there's an easy way to do this using bitwise operators at all. You'd need to use decimal operators like modulo 10 (% 10).

Creating a .bashrc file in your home directory also works. That way you don't have to copy your .bash_profile every time you install a new version of git bash.

1. To get an encoding parameter in Python 2:

If you only need to support Python 2.6 and 2.7 you can use io.open instead of open. io is the new io subsystem for Python 3, and it exists in Python 2,6 ans 2.7 as well. Please be aware that in Python 2.6 (as well as 3.0) it's implemented purely in python and very slow, so if you need speed in reading files, it's not a good option.

If you need speed, and you need to support Python 2.6 or earlier, you can use codecs.open instead. It also has an encoding parameter, and is quite similar to io.open except it handles line-endings differently.

2. To get a Python 3 open() style file handler which streams bytestrings:

open(filename, 'rb')

Note the 'b', meaning 'binary'.

Most guides I've seen suggest that you should use

if A:

unless you have a reason to be more specific.

There are some slight differences. There are values other than None that return False, for example empty lists, or 0, so have a think about what it is you're really testing for.

Use the Pandas library to create a dataframe of the csv data.
Name the fields either by including them in the csv file's first line or in code by using the dataframe's columns method.
Then create a list of model instances.
Finally use the django method .bulk_create() to send your list of model instances to the database table.

The read_csv function in pandas is great for reading csv files and gives you lots of parameters to skip lines, omit fields, etc.

import pandas as pd

tmp_data=pd.read_csv('file.csv',sep=';')
#ensure fields are named~ID,Product_ID,Name,Ratio,Description
#concatenate name and Product_id to make a new field a la Dr.Dee's answer
products = [
    Product(
        name = tmp_data.ix[row]['Name'] 
        description = tmp_data.ix[row]['Description'],
        price = tmp_data.ix[row]['price'],
    )
    for row in tmp_data['ID']
]
Product.objects.bulk_create(products)

I was using the answer by mmrs151 but saving each row (instance) was very slow and any fields containing the delimiting character (even inside of quotes) were not handled by the open() -- line.split(';') method.

Pandas has so many useful caveats, it is worth getting to know

On top of what @wisekiddo said, you can also modify your build settings in the project.pbxproj file by setting the Swift 3 @obj Inference to default like SWIFT_SWIFT3_OBJC_INFERENCE = Default; for your build flavors (i.e. debug and release), especially if you're coming from some other environment besides Xcode

You can either choose to set the headers manually, or make an HTTP interceptor that automatically sets header(s) every time a request is being made.

Manually

Setting a header:

http
  .post('/api/items/add', body, {
    headers: new HttpHeaders().set('Authorization', 'my-auth-token'),
  })
  .subscribe();

Setting headers:

this.http
.post('api/items/add', body, {
  headers: new HttpHeaders({
    'Authorization': 'my-auth-token',
    'x-header': 'x-value'
  })
}).subscribe()

Local variable (immutable instantiate again)

let headers = new HttpHeaders().set('header-name', 'header-value');
headers = headers.set('header-name-2', 'header-value-2');

this.http
  .post('api/items/add', body, { headers: headers })
  .subscribe()

The HttpHeaders class is immutable, so every set() returns a new instance and applies the changes.

From the Angular docs.

HTTP interceptor

A major feature of @angular/common/http is interception, the ability to declare interceptors which sit in between your application and the backend. When your application makes a request, interceptors transform it before sending it to the server, and the interceptors can transform the response on its way back before your application sees it. This is useful for everything from authentication to logging.

From the Angular docs.

Make sure you use @angular/common/http throughout your application. That way your requests will be catched by the interceptor.

Step 1, create the service:

import * as lskeys from './../localstorage.items';
import { Observable } from 'rxjs/Observable';
import { Injectable } from '@angular/core';
import { HttpEvent, HttpInterceptor, HttpHandler, HttpRequest, HttpHeaders } from '@angular/common/http';

@Injectable()
export class HeaderInterceptor implements HttpInterceptor {

    intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
        if (true) { // e.g. if token exists, otherwise use incomming request.
            return next.handle(req.clone({
                setHeaders: {
                    'AuthenticationToken': localStorage.getItem('TOKEN'),
                    'Tenant': localStorage.getItem('TENANT')
                }
            }));
        }
        else {
            return next.handle(req);
        }
    }
}

Step 2, add it to your module:

providers: [
    {
      provide: HTTP_INTERCEPTORS,
      useClass: HeaderInterceptor,
      multi: true // Add this line when using multiple interceptors.
    },
    // ...
  ]

First check if you have configured JDK correctly:

• Go to File->Project Structure -> SDKs
• your JDK home path should be something like this: /Library/Java/JavaVirtualMachine/jdk.1.7.0_79.jdk/Contents/Home
• Hit Apply and then OK

Secondly check if you have provided in path in Library's section

• Go to File->Project Structure -> Libraries
• Hit the + button
• Add the path to your src folder
• Hit Apply and then OK

This should fix the problem

In your view:

{% if user.is_authenticated %}
<p>{{ user }}</p>
{% endif %}

In you controller functions add decorator:

from django.contrib.auth.decorators import login_required
@login_required
def privateFunction(request):

You can either use

<h:outputText value="#{param['id']}" /> or

<h:outputText value="#{request.getParameter('id')}" />

However if you want to pass the parameters to your backing beans, using f:viewParam is probably what you want. "A view parameter is a mapping between a query string parameter and a model value."

<f:viewParam name="id" value="#{blog.entryId}"/>

This will set the id param of the GET parameter to the blog bean's entryId field. See http://java.dzone.com/articles/bookmarkability-jsf-2 for the details.

I hope this answer helps:

SELECT (CAST(id AS NVARCHAR)+','+name) AS COMBINED_COLUMN FROM TABLENAME;

Some examples:

Round(1.5) = 2
Round(2.5) = 2
Round(1.5, MidpointRounding.AwayFromZero) = 2
Round(2.5, MidpointRounding.AwayFromZero) = 3
Round(1.55, 1) = 1.6
Round(1.65, 1) = 1.6
Round(1.55, 1, MidpointRounding.AwayFromZero) = 1.6
Round(1.65, 1, MidpointRounding.AwayFromZero) = 1.7

Truncate(2.10) = 2
Truncate(2.00) = 2
Truncate(1.90) = 1
Truncate(1.80) = 1

I don't think so. The API's will provide access to delayed quotes, there is no way that real time data or tick data, will be provided for free.

Depending on the schema/account you are using to connect to the database, I would suspect you are missing a grant to the account you are using to connect to the database.

Connect as PCT account in the database, then grant the account you are using select access for the table.

grant select on pi_int to Account_used_to_connect

I had same issue. No need to re install.

Any chance your IIS is configured to require SSL on connections to your site/application?

The default data directory for MongoDB is /data/db.

This can be overridden by a dbpath option specified on the command line or in a configuration file.

If you install MongoDB via a package manager such as Homebrew or MacPorts these installs typically create a default data directory other than /data/db and set the dbpath in a configuration file.

If a dbpath was provided to mongod on startup you can check the value in the mongo shell:

db.serverCmdLineOpts()

You would see a value like:

"parsed" : {
    "dbpath" : "/usr/local/data"
},

Simple use of _.each

_.each(['Hello', 'World!'], function(word){_x000D_
    console.log(word);_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.3/underscore-min.js"></script>

Here's simple example that could use _.each:

function basket() {_x000D_
    this.items = [];_x000D_
    this.addItem = function(item) {_x000D_
        this.items.push(item);_x000D_
    };_x000D_
    this.show = function() {_x000D_
        console.log('items: ', this.items);_x000D_
    }_x000D_
}_x000D_
_x000D_
var x = new basket();_x000D_
x.addItem('banana');_x000D_
x.addItem('apple');_x000D_
x.addItem('kiwi');_x000D_
x.show();

Output:

items:  [ 'banana', 'apple', 'kiwi' ]

Instead of calling addItem multiple times you could use underscore this way:

_.each(['banana', 'apple', 'kiwi'], function(item) { x.addItem(item); });

which is identical to calling addItem three times sequentially with these items. Basically it iterates your array and for each item calls your anonymous callback function that calls x.addItem(item). The anonymous callback function is similar to addItem member function (e.g. it takes an item) and is kind of pointless. So, instead of going through anonymous function it's better that _.each avoids this indirection and calls addItem directly:

_.each(['banana', 'apple', 'kiwi'], x.addItem);

but this won't work, as inside basket's addItem member function this won't refer to your x basket that you created. That's why you have an option to pass your basket x to be used as [context]:

_.each(['banana', 'apple', 'kiwi'], x.addItem, x);

Full example that uses _.each and context:

function basket() {_x000D_
    this.items = [];_x000D_
    this.addItem = function(item) {_x000D_
        this.items.push(item);_x000D_
    };_x000D_
    this.show = function() {_x000D_
        console.log('items: ', this.items);_x000D_
    }_x000D_
}_x000D_
var x = new basket();_x000D_
_.each(['banana', 'apple', 'kiwi'], x.addItem, x);_x000D_
x.show();

<script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.3/underscore-min.js"></script>

In short, if callback function that you pass to _.each in any way uses this then you need to specify what this should be referring to inside your callback function. It may seem like x is redundant in my example, but x.addItem is just a function and could be totally unrelated to x or basket or any other object, for example:

function basket() {_x000D_
    this.items = [];_x000D_
    this.show = function() {_x000D_
        console.log('items: ', this.items);_x000D_
    }_x000D_
}_x000D_
function addItem(item) {_x000D_
    this.items.push(item);_x000D_
};_x000D_
_x000D_
var x = new basket();_x000D_
_.each(['banana', 'apple', 'kiwi'], addItem, x);_x000D_
x.show();

<script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.3/underscore-min.js"></script>

In other words, you bind some value to this inside your callback, or you may as well use bind directly like this:

_.each(['banana', 'apple', 'kiwi'], addItem.bind(x));

how this feature can be useful with some different underscore methods?

In general, if some underscorejs method takes a callback function and if you want that callback be called on some member function of some object (e.g. a function that uses this) then you may bind that function to some object or pass that object as the [context] parameter and that's the primary intention. And at the top of underscorejs documentation, that's exactly what they state: The iteratee is bound to the context object, if one is passed

You can do that by using this simple code:

Object.keys(myObject).length

Do as follow,

• Click on commit
• Select all by pressing CMD+A that you want to delete or discard
• Right click on the selected uncommitted files that you want to delete
• Select Remove from the drop-down list

you have a lot of answers in the post

Notification in depth

CODE

Intent intent = new Intent(this, SecondActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this,0,intent,0);

NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(context)
                        .setSmallIcon(R.drawable.your_notification_icon)
                        .setContentTitle("Notification Title")
                        .setContentText("Notification ")
                        .setContentIntent(pendingIntent );

NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, mBuilder.build());

Depth knowledge

Notification can be build using Notification. Builder or NotificationCompat.Builder classes.
But if you want backward compatibility you should use NotificationCompat.Builder class as it is part of v4 Support library as it takes care of heavy lifting for providing consistent look and functionalities of Notification for API 4 and above.

Core Notification Properties

A notification has 4 core properties (3 Basic display properties + 1 click action property)

• Small icon
• Title
• Text
• Button click event (Click event when you tap the notification )

Button click event is made optional on Android 3.0 and above. It means that you can build your notification using only display properties if your minSdk targets Android 3.0 or above. But if you want your notification to run on older devices than Android 3.0 then you must provide Click event otherwise you will see IllegalArgumentException.

Notification Display

Notification are displayed by calling notify() method of NotificationManger class

notify() parameters

There are two variants available for notify method

notify(String tag, int id, Notification notification)

or

notify(int id, Notification notification)

notify method takes an integer id to uniquely identify your notification. However, you can also provide an optional String tag for further identification of your notification in case of conflict.

This type of conflict is rare but say, you have created some library and other developers are using your library. Now they create their own notification and somehow your notification and other dev's notification id is same then you will face conflict.

Notification after API 11 (More control)

API 11 provides additional control on Notification behavior

• Notification Dismissal
  By default, if a user taps on notification then it performs the assigned click event but it does not clear away the notification. If you want your notification to get cleared when then you should add this

  mBuilder.setAutoClear(true);

• Prevent user from dismissing notification
  A user may also dismiss the notification by swiping it. You can disable this default behavior by adding this while building your notification

  mBuilder.setOngoing(true);

• Positioning of notification
  You can set the relative priority to your notification by

  mBuilder.setOngoing(int pri);

If your app runs on lower API than 11 then your notification will work without above mentioned additional features. This is the advantage to choosing NotificationCompat.Builder over Notification.Builder

Notification after API 16 (More informative)

With the introduction of API 16, notifications were given so many new features
Notification can be so much more informative.
You can add a bigPicture to your logo. Say you get a message from a person now with the mBuilder.setLargeIcon(Bitmap bitmap) you can show that person's photo. So in the statusbar you will see the icon when you scroll you will see the person photo in place of the icon. There are other features too

• Add a counter in the notification
• Ticker message when you see the notification for the first time
• Expandable notification
• Multiline notification and so on

I tried the following three methods, my file size is 1M, and I got results:

I run the program several times it looks that BufferedReader is faster.

    try (Scanner fileScanner = new Scanner(inputStream, StandardCharsets.UTF_8.name())) {
        while (fileScanner.hasNextLine()) {
            String line = fileScanner.nextLine();
            //System.out.println(line);
        }
    }

In Java 8, they introduced forEach. Using it List, Maps can be looped.

Loop a List using for each

List<String> someList = new ArrayList<String>();
someList.add("A");
someList.add("B");
someList.add("C");

someList.forEach(listItem -> System.out.println(listItem))

or

someList.forEach(listItem-> {
     System.out.println(listItem); 
});

Loop a Map using for each

Map<String, String> mapList = new HashMap<>();
    mapList.put("Key1", "Value1");
    mapList.put("Key2", "Value2");
    mapList.put("Key3", "Value3");

mapList.forEach((key,value)->System.out.println("Key: " + key + " Value : " + value));

or

mapList.forEach((key,value)->{
    System.out.println("Key : " + key + " Value : " + value);
});

unsigned mod(int a, unsigned b) {
    return (a >= 0 ? a % b : b - (-a) % b);
}

If the array is a global, static, or automatic variable (int array[10];), then sizeof(array)/sizeof(array[0]) works.

If it is a dynamically allocated array (int* array = malloc(sizeof(int)*10);) or passed as a function argument (void f(int array[])), then you cannot find its size at run-time. You will have to store the size somewhere.
Note that sizeof(array)/sizeof(array[0]) compiles just fine even for the second case, but it will silently produce the wrong result.

you can saperate string using the below code

   String thisString="Hello world";

   String[] parts = theString.split(" ");

   String first = parts[0];//"hello"

    String second = parts[1];//"World"

To answer your main question: “How do I simulate a hover with a touch in touch enabled browsers?”

Simply allow ‘clicking’ the element (by tapping the screen), and then trigger the hover event using JavaScript.

var p = document.getElementsByTagName('p')[0];
p.onclick = function() {
 // Trigger the `hover` event on the paragraph
 p.onhover.call(p);
};

This should work, as long as there’s a hover event on your device (even though it normally isn’t used).

Update: I just tested this technique on my iPhone and it seems to work fine. Try it out here: http://jsfiddle.net/mathias/YS7ft/show/light/

If you want to use a ‘long touch’ to trigger hover instead, you can use the above code snippet as a starting point and have fun with timers and stuff ;)

I actually disagree with SLaks. That solution did not work for me. Exception did not happen as expected. But this code worked for me:

if(System.IO.Directory.Exists(path))
{
    ...
}

if anyone needs this for NGINX configuration file here is the snippet:

location ~* \.(js|css|xml|gz)$ {
    add_header Vary "Accept-Encoding";
    (... other headers or rules ...)
}

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

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

No need to get too complicated. If all you need is ² then use the unicode representation.

http://en.wikipedia.org/wiki/Unicode_subscripts_and_superscripts

(which is how I assume you got the ² to appear in your question. )

An alternative to whoami is id -u -n.

id -u will return the user id (e.g. 0 for root).

An unmodifiable map may still change. It is only a view on a modifiable map, and changes in the backing map will be visible through the unmodifiable map. The unmodifiable map only prevents modifications for those who only have the reference to the unmodifiable view:

Map<String, String> realMap = new HashMap<String, String>();
realMap.put("A", "B");

Map<String, String> unmodifiableMap = Collections.unmodifiableMap(realMap);

// This is not possible: It would throw an 
// UnsupportedOperationException
//unmodifiableMap.put("C", "D");

// This is still possible:
realMap.put("E", "F");

// The change in the "realMap" is now also visible
// in the "unmodifiableMap". So the unmodifiableMap
// has changed after it has been created.
unmodifiableMap.get("E"); // Will return "F". 

In contrast to that, the ImmutableMap of Guava is really immutable: It is a true copy of a given map, and nobody may modify this ImmutableMap in any way.

Update:

As pointed out in a comment, an immutable map can also be created with the standard API using

Map<String, String> immutableMap = 
    Collections.unmodifiableMap(new LinkedHashMap<String, String>(realMap)); 

This will create an unmodifiable view on a true copy of the given map, and thus nicely emulates the characteristics of the ImmutableMap without having to add the dependency to Guava.

I wanted to filter out dfbc rows that had a BUSINESS_ID that was also in the BUSINESS_ID of dfProfilesBusIds

dfbc = dfbc[~dfbc['BUSINESS_ID'].isin(dfProfilesBusIds['BUSINESS_ID'])]

What about re === str (case compare)?

Since it evaluates to true or false and has no need for storing matches, returning match index and that stuff, I wonder if it would be an even faster way of matching than =~.

Ok, I tested this. =~ is still faster, even if you have multiple capture groups, however it is faster than the other options.

BTW, what good is freeze? I couldn't measure any performance boost from it.

As stated in High Performance Django Book and Go through this Cal Henderson

See further details as mentioned below:

It’s not uncommon to hear people say “Django doesn’t scale”. Depending on how you look at it, the statement is either completely true or patently false. Django, on its own, doesn’t scale.

The same can be said of Ruby on Rails, Flask, PHP, or any other language used by a database-driven dynamic website.

The good news, however, is that Django interacts beautifully with a suite of caching and load balancing tools that will allow it to scale to as much traffic as you can throw at it.

Contrary to what you may have read online, it can do so without replacing core components often labeled as “too slow” such as the database ORM or the template layer.

Disqus serves over 8 billion page views per month. Those are some huge numbers.

These teams have proven Django most certainly does scale. Our experience here at Lincoln Loop backs it up.

We’ve built big Django sites capable of spending the day on the Reddit homepage without breaking a sweat.

Django’s scaling success stories are almost too numerous to list at this point.

It backs Disqus, Instagram, and Pinterest. Want some more proof? Instagram was able to sustain over 30 million users on Django with only 3 engineers (2 of which had no back-end development

I've faced with the same problem, have struggled a couple of day with it and should say that the most easiest way to overcome I found this is to use fragment.hide() / fragment.show() when tab is selected/unselected().

public void onTabUnselected(ActionBar.Tab tab, FragmentTransaction ft)
{
    if (mFragment != null)
        ft.hide(mFragment);
}

When screen rotation occurs all parent and child fragments get correctly destroyed.

This approach has also one additional advantage - using hide()/show() does not cause fragment views to loose their state, so there is no need to restore the previous scroll position for ScrollViews for example.

The problem is that I don't know whether it is correct to not detach fragments when they are not visible. I think the official example of TabListener is designed with a thought in mind that fragments are reusable and you should not pollute with them memory, however, I think if you have just a few tabs and you know that users will be switching between them frequently it will be appropriate to keep them attached to the current activity.

I would like to hear comments from more experienced developers.

• nesting SUBSTITUTE() in a string can be nasty, however, it's always possible to arrange it:

For debugging purposes in case you want to look up a raw Mat::type in a debugger:

+--------+----+----+----+----+------+------+------+------+
|        | C1 | C2 | C3 | C4 | C(5) | C(6) | C(7) | C(8) |
+--------+----+----+----+----+------+------+------+------+
| CV_8U  |  0 |  8 | 16 | 24 |   32 |   40 |   48 |   56 |
| CV_8S  |  1 |  9 | 17 | 25 |   33 |   41 |   49 |   57 |
| CV_16U |  2 | 10 | 18 | 26 |   34 |   42 |   50 |   58 |
| CV_16S |  3 | 11 | 19 | 27 |   35 |   43 |   51 |   59 |
| CV_32S |  4 | 12 | 20 | 28 |   36 |   44 |   52 |   60 |

+--------+----+----+----+----+------+------+------+------+

So for example, if type = 30 then OpenCV data type is CV_64FC4. If type = 50 then the OpenCV data type is CV_16UC(7).

If you have SQL Server Management Studio, you can just Copy from Excel and Paste into the table in Management Studio, using your mouse. Just

1. Go to the table you want to paste into.
2. Select "Edit Top 200 Rows".
3. Right-click anywhere and select Paste.

Before you do this, you must match the columns between Excel and Management Studio. Also, you must place any non-editable columns last (right-most) using the Table Designer in Management Studio.

The whole procedure takes seconds (to set-up and start - not necessarily to execute) and doesn't require any SQL statements.

Install PIL(Python Image Library) :

then:

from PIL import Image
myImage = Image.open("your_image_here");
myImage.show();

If you are using web api then you should make a http POST call to URL : https://www.googleapis.com/oauth2/v4/token with following request body

client_id: <YOUR_CLIENT_ID>
client_secret: <YOUR_CLIENT_SECRET>
refresh_token: <REFRESH_TOKEN_FOR_THE_USER>
grant_type: refresh_token

refresh token never expires so you can use it any number of times. The response will be a JSON like this:

{
  "access_token": "your refreshed access token",
  "expires_in": 3599,
  "scope": "Set of scope which you have given",
  "token_type": "Bearer"
}

Put the stuff you need on a page in a div and use page-break-inside:avoid on that div. Your div will stay on one page and go onto a second or third page if needed, but the next div, should it have to do a page break, should start on the next page.

If you choose to use "cv2.waitKey(0)", be sure that you have written "cv2.waitKey(0)" instead of "cv2.waitkey(0)", because that lowercase "k" might freeze your program too.

Yes, you have to copy all 387 constructors. You can do some reuse by redirecting them:

  public Bar(int i): base(i) {}
  public Bar(int i, int j) : base(i, j) {}

but that's the best you can do.

Just try this code this code work with me

Tested in Xcode 9.4, Swift 4 Another way to solve this issue is , You can add

override func layoutSubviews() {
        self.frame = (self.superview?.bounds)!
    }

in subview class.

There are two options for cross thread operations.

Control.InvokeRequired Property 

and second one is to use

SynchronizationContext Post Method

Control.InvokeRequired is only useful when working controls inherited from Control class while SynchronizationContext can be used anywhere. Some useful information is as following links

Did you check also the following site And check the introduction article of Opera

on mac, using uk english keyboard layout to reach quickcomment in android studio the key combination is:

Do you need the cursor to be a "wait" cursor only when it's over that particular page/usercontrol? If not, I'd suggest using Mouse.OverrideCursor:

Mouse.OverrideCursor = Cursors.Wait;
try
{
    // do stuff
}
finally
{
    Mouse.OverrideCursor = null;
}

This overrides the cursor for your application rather than just for a part of its UI, so the problem you're describing goes away.

I think what you're asking about is how to create responsive spacing between rows or col-xx-xx classes.

You can definitely do this with the col-xx-offset-xx class:

<div class="col-xs-4">
</div>

<div class="col-xs-7 col-xs-offset-1">
</div>

As for adding margin or padding directly to elements, there are some simple ways to do this depending on your element. You can use btn-lg or label-lg or well-lg. If you're ever wondering, how can i give this alittle padding. Try adding the primary class name + lg or sm or md depending on your size needs:

<button class="btn btn-success btn-lg btn-block">Big Button w/ Display: Block</button>

Apparently you don't need to specify height at all! Which is great if it changes for some reason (you resize components or change font sizes).

I just followed this tutorial and everything worked: http://natashatherobot.com/ios-autolayout-scrollview/

(Side note: There is no need to implement viewDidLayoutSubviews unless you want to center the view, so the list of steps is even shorter).

Hope that helps!

On the off chance anyone else ever runs into this extremely specific issue.. Something inside PyTorch breaks DLL loading. Once you run import torch, any further DLL loads will fail. So if you're using PyTorch and loading your own DLLs you'll have to rearrange your code to import all DLLs first. Confirmed w/ PyTorch 1.5.0 on Python 3.7

Is canny your own function? Do you use Canny from OpenCV inside it? If yes check if you feed suitable argument for Canny - first Canny argument should meet following criteria:

• type: <type 'numpy.ndarray'>
• dtype: dtype('uint8')
• being single channel or simplyfing: grayscale, that is 2D array, i.e. its shape should be 2-tuple of ints (tuple containing exactly 2 integers)

You can check it by printing respectively

type(variable_name)
variable_name.dtype
variable_name.shape

Replace variable_name with name of variable you feed as first argument to Canny.

account.withdraw(balance, 2500);
account.deposit(balance, 3000);

you might want to make withdraw and deposit non-static and let it modify the balance

public void withdraw(double withdrawAmount) {
    balance = balance - withdrawAmount;
}

public void deposit(double depositAmount) {
    balance = balance + depositAmount;
}   

and remove the balance parameter from the call

If attribute routing is being used, you can use the [FromUri] and [FromBody] attributes.

Example:

[HttpPost()]
[Route("api/products/{id:int}")]
public HttpResponseMessage AddProduct([FromUri()] int id,  [FromBody()] Product product)
{
  // Add product
}

If you want to delete for example the last 3 commits, run the following command to remove the changes from the file system (working tree) and commit history (index) on your local branch:

git reset --hard HEAD~3

Then run the following command (on your local machine) to force the remote branch to rewrite its history:

git push --force

Congratulations! All DONE!

Some notes:

You can retrieve the desired commit id by running

git log

Then you can replace HEAD~N with <desired-commit-id> like this:

git reset --hard <desired-commit-id>

If you want to keep changes on file system and just modify index (commit history), use --soft flag like git reset --soft HEAD~3. Then you have chance to check your latest changes and keep or drop all or parts of them. In the latter case runnig git status shows the files changed since <desired-commit-id>. If you use --hard option, git status will tell you that your local branch is exactly the same as the remote one. If you don't use --hard nor --soft, the default mode is used that is --mixed. In this mode, git help reset says:

Resets the index but not the working tree (i.e., the changed files are preserved but not marked for commit) and reports what has not been updated.

You can refer to this link.

Unlike Amagrammer said, it's possible. You have to subclass your navigationController. I explained everything here (including example code).

1. To properly purge the queue of waiting tasks you have to stop all the workers (http://celery.readthedocs.io/en/latest/faq.html#i-ve-purged-messages-but-there-are-still-messages-left-in-the-queue):

$ sudo rabbitmqctl stop

or (in case RabbitMQ/message broker is managed by Supervisor):

$ sudo supervisorctl stop all

2. ...and then purge the tasks from a specific queue:

$ cd <source_dir>
$ celery amqp queue.purge <queue name>

3. Start RabbitMQ:

$ sudo rabbitmqctl start

or (in case RabbitMQ is managed by Supervisor):

$ sudo supervisorctl start all

I find that there are 3 package-based solutions to solve the problem. They are pyenchant, wordnet and corpus(self-defined or from ntlk). Pyenchant couldn't installed easily in win64 with py3. Wordnet doesn't work very well because it's corpus isn't complete. So for me, I choose the solution answered by @Sadik, and use 'set(words.words())' to speed up.

First:

pip3 install nltk
python3

import nltk
nltk.download('words')

Then:

from nltk.corpus import words
setofwords = set(words.words())

print("hello" in setofwords)
>>True

The relevant part of C11 standard draft n1570 6.7.9 initialization says:

14 An array of character type may be initialized by a character string literal or UTF-8 string literal, optionally enclosed in braces. Successive bytes of the string literal (including the terminating null character if there is room or if the array is of unknown size) initialize the elements of the array.

and

21 If there are fewer initializers in a brace-enclosed list than there are elements or members of an aggregate, or fewer characters in a string literal used to initialize an array of known size than there are elements in the array, the remainder of the aggregate shall be initialized implicitly the same as objects that have static storage duration.

Thus, the '\0' is appended, if there is enough space, and the remaining characters are initialized with the value that a static char c; would be initialized within a function.

Finally,

10 If an object that has automatic storage duration is not initialized explicitly, its value is indeterminate. If an object that has static or thread storage duration is not initialized explicitly, then:

[--]

• if it has arithmetic type, it is initialized to (positive or unsigned) zero;

[--]

Thus, char being an arithmetic type the remainder of the array is also guaranteed to be initialized with zeroes.

• window.open will open a new browser with the specified URL.

• window.location.href will open the URL in the window in which the code is called.

Note also that window.open() is a function on the window object itself whereas window.location is an object that exposes a variety of other methods and properties.

I have done following and it resolve an issue with recyclerview same you may use for other widget as well if it's not working in eclipse project.

• Go to sdk\extras\android\m2repository\com\android\support\recyclerview-v7\21.0.0-rc1 directory

• Copy recyclerview-v7-21.0.0-rc1.aar file and rename it as .zip

• Unzip the file, you will get classes.jar (rename the jar file more meaningful name)

• Use the following jar in your project build path or lib directory.

and it resolve your error.

happy coding :)

You may also use:

request.POST.get('section','') # => [39]
request.POST.get('MAINS','') # => [137] 
request.GET.get('section','') # => [39]
request.GET.get('MAINS','') # => [137]

Using this ensures that you don't get an error. If the POST/GET data with any key is not defined then instead of raising an exception the fallback value (second argument of .get() will be used).

Chiming in with another example: This can be useful if "default" is an unexpected case, and you want to log the error but also do something sensible. Example from some of my own code:

  switch (style)
  {
  default:
    MSPUB_DEBUG_MSG(("Couldn't match dash style, using solid line.\n"));
  case SOLID:
    return Dash(0, RECT_DOT);
  case DASH_SYS:
  {
    Dash ret(shapeLineWidth, dotStyle);
    ret.m_dots.push_back(Dot(1, 3 * shapeLineWidth));
    return ret;
  }
  // more cases follow
  }

You may try with below query :

INSERT INTO errortable (dateupdated,table1id)
VALUES (to_date(to_char(sysdate,'dd/mon/yyyy hh24:mi:ss'), 'dd/mm/yyyy hh24:mi:ss' ),1083 );

To view the result of it:

SELECT to_char(hire_dateupdated, 'dd/mm/yyyy hh24:mi:ss') 
FROM errortable 
    WHERE table1id = 1083;

Try Ctrl + K + D (don't lift the Ctrl key in between).

This one works for me.

`Post.find().sort({postedon: -1}).find(function (err, sortedposts){
    if (err) 
        return res.status(500).send({ message: "No Posts." });
    res.status(200).send({sortedposts : sortedposts});
 });`

Don't forget the padding and margins...

jQuery.fn.slideLeftHide = function(speed, callback) { 
  this.animate({ 
    width: "hide", 
    paddingLeft: "hide", 
    paddingRight: "hide", 
    marginLeft: "hide", 
    marginRight: "hide" 
  }, speed, callback);
}

jQuery.fn.slideLeftShow = function(speed, callback) { 
  this.animate({ 
    width: "show", 
    paddingLeft: "show", 
    paddingRight: "show", 
    marginLeft: "show", 
    marginRight: "show" 
  }, speed, callback);
}

With the speed/callback arguments added, it's a complete drop-in replacement for slideUp() and slideDown().

Just use DROP TABLE IF EXISTS:

DROP TABLE IF EXISTS `foo`;
CREATE TABLE `foo` ( ... );

Try searching the MySQL documentation first if you have any other problems.

CABForum Baseline Requirements

I see no one has mentioned the section in the Baseline Requirements yet. I feel they are important.

Q: SSL - How do Common Names (CN) and Subject Alternative Names (SAN) work together?
A: Not at all. If there are SANs, then CN can be ignored. -- At least if the software that does the checking adheres very strictly to the CABForum's Baseline Requirements.

(So this means I can't answer the "Edit" to your question. Only the original question.)

CABForum Baseline Requirements, v. 1.2.5 (as of 2 April 2015), page 9-10:

9.2.2 Subject Distinguished Name Fields
a. Subject Common Name Field
Certificate Field: subject:commonName (OID 2.5.4.3)
Required/Optional: Deprecated (Discouraged, but not prohibited)
Contents: If present, this field MUST contain a single IP address or Fully-Qualified Domain Name that is one of the values contained in the Certificate’s subjectAltName extension (see Section 9.2.1).

EDIT: Links from @Bruno's comment

RFC 2818: HTTP Over TLS, 2000, Section 3.1: Server Identity:

If a subjectAltName extension of type dNSName is present, that MUST be used as the identity. Otherwise, the (most specific) Common Name field in the Subject field of the certificate MUST be used. Although the use of the Common Name is existing practice, it is deprecated and Certification Authorities are encouraged to use the dNSName instead.

RFC 6125: Representation and Verification of Domain-Based Application Service Identity within Internet Public Key Infrastructure Using X.509 (PKIX) Certificates in the Context of Transport Layer Security (TLS), 2011, Section 6.4.4: Checking of Common Names:

[...] if and only if the presented identifiers do not include a DNS-ID, SRV-ID, URI-ID, or any application-specific identifier types supported by the client, then the client MAY as a last resort check for a string whose form matches that of a fully qualified DNS domain name in a Common Name field of the subject field (i.e., a CN-ID).

You need to unicode each element of the list individually

[x.encode('utf-8') for x in tmp]

Going forward, for graphical elements that are purely decorative, the best solution is to use:

android:importantForAccessibility="no"

This makes sense if your min SDK version is at least 16, since devices running lower versions will ignore this attribute.

If you're stuck supporting older versions, you should use (like others pointed out already):

android:contentDescription="@null"

Source: https://developer.android.com/guide/topics/ui/accessibility/apps#label-elements

I tried out most options mentioned previously but found this small and intuitive package to be the best: pympler

It's quite straight forward to trace objects that were not garbage-collected, check this small example:

install package via pip install pympler

from pympler.tracker import SummaryTracker
tracker = SummaryTracker()

# ... some code you want to investigate ...

tracker.print_diff()

The output shows you all the objects that have been added, plus the memory they consumed.

Sample output:

                                 types |   # objects |   total size
====================================== | =========== | ============
                                  list |        1095 |    160.78 KB
                                   str |        1093 |     66.33 KB
                                   int |         120 |      2.81 KB
                                  dict |           3 |       840 B
      frame (codename: create_summary) |           1 |       560 B
          frame (codename: print_diff) |           1 |       480 B

This package provides a number of more features. Check pympler's documentation, in particular the section Identifying memory leaks.

Set the local branch one revision back (HEAD^ means one revision back):

git reset --hard HEAD^

Push the changes to origin:

git push --force

You will have to force pushing because otherwise git would recognize that you're behind origin by one commit and nothing will change.

Doing it with --force tells git to overwrite HEAD in the remote repo without respecting any advances there.

If someone is interested in the similar problem, but is not working with XAML, here's my solution:

var B1 = new Border();
B1.BorderBrush = Brushes.Black;
B1.BorderThickness = new Thickness(0, 1, 0, 0); // You can specify here which borders do you want
YourPanel.Children.Add(B1);

You need to instantiate the other classes inside the main class;

Date d = new Date(params);
TemperatureRange t = new TemperatureRange(params);

You can then call their methods with:

object.methodname(params);
d.method();

You currently have constructors in your other classes. You should not return anything in these.

public Date(params){
    set variables for date object
}

Next you need a method to reference.

public returnType methodName(params){
  return something;
}

I've taken your code and adapted it with library react-form-with-constraints: https://codepen.io/tkrotoff/pen/LLraZp

const {
  FormWithConstraints,
  FieldFeedbacks,
  FieldFeedback
} = ReactFormWithConstraints;

class Form extends React.Component {
  handleChange = e => {
    this.form.validateFields(e.target);
  }

  contactSubmit = e => {
    e.preventDefault();

    this.form.validateFields();

    if (!this.form.isValid()) {
      console.log('form is invalid: do not submit');
    } else {
      console.log('form is valid: submit');
    }
  }

  render() {
    return (
      <FormWithConstraints
        ref={form => this.form = form}
        onSubmit={this.contactSubmit}
        noValidate>

        <div className="col-md-6">
          <input name="name" size="30" placeholder="Name"
                 required onChange={this.handleChange}
                 className="form-control" />

          </FieldFeedbacks>

          <FieldFeedbacks for="phone">
            <FieldFeedback when="*" />
          </FieldFeedbacks>

          <input name="address" size="30" placeholder="Address"
                 required onChange={this.handleChange}

          <FieldFeedbacks for="address">
            <FieldFeedback when="*" />
          </FieldFeedbacks>
        </div>

        <div className="col-md-6">
          <textarea name="comments" cols="40" rows="20" placeholder="Message"
                    required minLength={5} maxLength={50}
                    onChange={this.handleChange}
                    className="form-control" />
          <FieldFeedbacks for="comments">
            <FieldFeedback when="*" />
          </FieldFeedbacks>
        </div>

        <div className="col-md-12">
          <button className="btn btn-lg btn-primary">Send Message</button>
        </div>
      </FormWithConstraints>
    );
  }
}

At any channel page with "user" url for example http://www.youtube.com/user/klauskkpm, without API call, from YouTube UI, click a video of the channel (in its "VIDEOS" tab) and click the channel name on the video. Then you can get to the page with its "channel" url for example https://www.youtube.com/channel/UCfjTOrCPnAblTngWAzpnlMA.

if (file_exists('http://www.mydomain.com/images/'.$filename)) {}

This didn't work for me. The way I did it was using getimagesize.

$src = 'http://www.mydomain.com/images/'.$filename;

if (@getimagesize($src)) {

Note that the '@' will mean that if the image does not exist (in which case the function would usually throw an error: getimagesize(http://www.mydomain.com/images/filename.png) [function.getimagesize]: failed) it will return false.

dotnet is the official home of .NET on GitHub. It's a great starting point to find many .NET OSS projects from Microsoft and the community, including many that are part of the .NET Foundation.

This may be a great start to support Linux.

A moving average can also be calculated and visualized directly in a line chart by using the following code:

Example using stock price data:

import pandas_datareader.data as web
import matplotlib.pyplot as plt
import datetime
plt.style.use('ggplot')

# Input variables
start = datetime.datetime(2016, 1, 01)
end = datetime.datetime(2018, 3, 29)
stock = 'WFC'

# Extrating data
df = web.DataReader(stock,'morningstar', start, end)
df = df['Close']

print df 

plt.plot(df['WFC'],label= 'Close')
plt.plot(df['WFC'].rolling(9).mean(),label= 'MA 9 days')
plt.plot(df['WFC'].rolling(21).mean(),label= 'MA 21 days')
plt.legend(loc='best')
plt.title('Wells Fargo\nClose and Moving Averages')
plt.show()

Here is the Kotlin solution:

override fun onKeyUp(keyCode: Int, event: KeyEvent?): Boolean {
    if (event?.action != ACTION_UP || event.keyCode != KEYCODE_BACK) {
        return super.onKeyUp(keyCode, event)
    }

    if (mWebView.canGoBack()) {
        mWebView.goBack()
    } else {
        finish()
    }
    return true

The location of the $_SESSION variable storage is determined by PHP's session.save_path configuration. Usually this is /tmp on a Linux/Unix system. Use the phpinfo() function to view your particular settings if not 100% sure by creating a file with this content in the DocumentRoot of your domain:

<?php
    phpinfo();
?>

Here is the link to the PHP documentation on this configuration setting:

http://php.net/manual/en/session.configuration.php#ini.session.save-path

Go to MySQL installer and click Reconfigure (don't change any existing settings). This should start the server and you'll be off.

Run the installer from command line with argument /CustomInstallPath InstallationDirectory

See more command-line parameters and other installation information.

Note: this won't change location of all files, but only of those which can be (by design) installed onto different location. Be warned that there is many shared components which will be installed into shared repositories on drive C: without any possibility to change their path (unless you do some hacking using mklink /j (directory junction, i.e."hard link for folder"), but it is questionable whether it is worth it, because any Visual Studio updates will break those hard links. This is confirmed by people who tried that, although on Visual Studio 2012.)

Update: per recent comment, uninstallation of Visual Studio might be required before the above applies. Uninstallation command is like this: vs_community_ENU.exe /uninstall /force

Make sure they're really tabs! In bash, you can insert a tab using C-v TAB

$ echo "LOAD_SETTLED    LOAD_INIT       2011-01-13 03:50:01" | awk -F$'\t' '{print $1}'

For Bootstrap 2 Auto adjust model height dynamically

  //Auto adjust modal height on open 
  $('#modal').on('shown',function(){
     var offset = 0;
     $(this).find('.modal-body').attr('style','max-height:'+($(window).height()-offset)+'px !important;');
  });

No, this is, as you say "rubbish code". If it works as should, it is because browsers try to "read the writer's mind" - in other words, they have algorithms to try to make sense of "rubbish code", guess at the probable intent and internally change it into something that actually makes sense.

In other words, your code only works by accident, and probably not in all browsers.

Is this what you're trying to do?

<a href="#" onClick="alert('Hello World!')"><img title="The Link" /></a>

I would echo what Wyzard wrote but add that:

• for query parameters, HTML encoding is often exactly what the server is expecting; outside these, it is correct that URLEncoder should not be used
• the most recent URI spec is RFC 3986, so you should refer to that as a primary source

I wrote a blog post a while back about this subject: Java: safe character handling and URL building

By default you use curl without explicitly saying which request method to use. If you just pass in a HTTP URL like curl http://example.com it will use GET. If you use -d or -F curl will use POST, -I will cause a HEAD and -T will make it a PUT.

If for whatever reason you're not happy with these default choices that curl does for you, you can override those request methods by specifying -X [WHATEVER]. This way you can for example send a DELETE by doing curl -X DELETE [URL].

It is thus pointless to do curl -X GET [URL] as GET would be used anyway. In the same vein it is pointless to do curl -X POST -d data [URL]... But you can make a fun and somewhat rare request that sends a request-body in a GET request with something like curl -X GET -d data [URL].

Digging deeper

curl -GET (using a single dash) is just wrong for this purpose. That's the equivalent of specifying the -G, -E and -T options and that will do something completely different.

There's also a curl option called --get to not confuse matters with either. It is the long form of -G, which is used to convert data specified with -d into a GET request instead of a POST.

(I subsequently used my own answer here to populate the curl FAQ to cover this.)

Warnings

Modern versions of curl will inform users about this unnecessary and potentially harmful use of -X when verbose mode is enabled (-v) - to make users aware. Further explained and motivated in this blog post.

-G converts a POST + body to a GET + query

You can ask curl to convert a set of -d options and instead of sending them in the request body with POST, put them at the end of the URL's query string and issue a GET, with the use of `-G. Like this:

curl -d name=daniel -d grumpy=yes -G https://example.com/

Well it does this because you are converting a 64 bits pointer to an 32 bits integer so you loose information.

You can use a 64 bits integer instead howerver I usually use a function with the right prototype and I cast the function type : eg.

void thread_func(int arg){
...
}

and I create the thread like this :

pthread_create(&tid, NULL, (void*(*)(void*))thread_func, (void*)arg);

The closest thing is likely Dav Glass's experimental work using node.js, express and YUI3. Basically, he explains how YUI3 is used to render markup on the server side, then sent to the client where binding to event and data occurs. The beauty is YUI3 is used as-is on both the client and the server. Makes a lot of sense. The one big issue is there is not yet a production ready server-side DOM library.

screencast

Assuming you are referring to Django's Auth User, in your view:

def game(request):
  user = request.user

  gta = Game.objects.create(name="gta", owner=user)

You can return multiple value inside a xml data type in "case" expression, then extract them, also "else" block is available

SELECT 
xmlcol.value('(value1)[1]', 'NVARCHAR(MAX)') AS value1,
xmlcol.value('(value2)[1]', 'NVARCHAR(MAX)') AS value2
FROM
(SELECT CASE
WHEN <condition 1> THEN
CAST((SELECT a1 AS value1, b1 AS value2 FOR XML PATH('')) AS XML)
WHEN <condition 2> THEN
CAST((SELECT a2 AS value1, b2 AS value2 FOR XML PATH('')) AS XML)
ELSE
CAST((SELECT a3 AS value1, b3 AS value2 FOR XML PATH('')) AS XML)
END AS xmlcol
FROM <table>) AS tmp

In general for AnInterface and anInstance of any class:

AnInterface.class.isAssignableFrom(anInstance.getClass());

html, body {
    min-height: 100%;
}

Will do the trick.

By default, even html and body are only as big as the content they hold, but never more than the width/height of the windows. This can often lead to quite strange results.

There are some great ways do achieve a very good and scalable full background image.

I know this is quite an old question, but with Java 8's Streams you can get a range of ints like this:

// gives an IntStream of integers from 0 through Integer.MAX_VALUE
IntStream.rangeClosed(0, Integer.MAX_VALUE); 

Then you can do something like this:

if (IntStream.rangeClosed(0, Integer.MAX_VALUE).matchAny(n -> n == A)) {
    // do something
} else {
    // do something else 
}

You can also use the AddRange method

listBox1.Items.AddRange(myList.ToArray());

You probably need to do a git stash before you git pull, this is because it is reading your old config file. So do:

git stash
git pull
git commit -am <"say first commit">
git push

Also see git-stash(1) Manual Page.

Use find:

find . -maxdepth 1 -name "*string*" -print

It will find all files in the current directory (delete maxdepth 1 if you want it recursive) containing "string" and will print it on the screen.

If you want to avoid file containing ':', you can type:

find . -maxdepth 1 -name "*string*" ! -name "*:*" -print

If you want to use grep (but I think it's not necessary as far as you don't want to check file content) you can use:

ls | grep touch

But, I repeat, find is a better and cleaner solution for your task.

sudo apt-get remove nodejs
sudo apt-get remove npm

Then go to /etc/apt/sources.list.d and remove any node list if you have. Then do a

sudo apt-get update

Check for any .npm or .node folder in your home folder and delete those.

If you type

which node

you can see the location of the node. Try which nodejs and which npm too.

I would recommend installing node using Node Version Manager(NVM). That saved a lot of headache for me. You can install nodejs and npm without sudo using nvm.

Typically, you pass the goroutine a (possibly separate) signal channel. That signal channel is used to push a value into when you want the goroutine to stop. The goroutine polls that channel regularly. As soon as it detects a signal, it quits.

quit := make(chan bool)
go func() {
    for {
        select {
        case <- quit:
            return
        default:
            // Do other stuff
        }
    }
}()

// Do stuff

// Quit goroutine
quit <- true

Use this code very simple solution

 @Override
    public void onBackPressed() {
      super.onBackPressed(); // this line close the  app on backpress
 }

I know this is a bit old but the answer in short would be <load-on-startup> both occurrences have given the same id which is 1 twice. This may confuse loading sequence.

Inside OnCreate, add:

 webview.getSettings().setSupportZoom(true);
 webview.getSettings().setBuiltInZoomControls(true);
 webview.getSettings().setDisplayZoomControls(false);

Inside the html document, add:

<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=2, user-scalable=yes">
</head>
</html>

Inside javascript, omit:

//event.preventDefault ? event.preventDefault() : (event.returnValue = false);

In my case, the program was running fine, but after one day, I just ran into this problem without doing anything...

The solution was to manually add 'Main' as the Entry Point (before editing, the area was empty):

I have not used Selenium 2. Selenium 1.x has selenium.getTable("tablename".columnNumber.rowNumber) to reach the required cell. May be you can use webdriverbackedselenium and do this.

And you can get the total rows and columns by using

int numOfRows = selenium.getXpathCount("//table[@id='tableid']//tr")

int numOfCols=selenium.getXpathCount("//table[@id='tableid']//tr//td")

Put your parameters in a hash table and pass them like this:

$postParams = @{username='me';moredata='qwerty'}
Invoke-WebRequest -Uri http://example.com/foobar -Method POST -Body $postParams

What I did

Html

    <div>
      <div class="register">
         /* your content*/    
      </div>
      <div class="footer" />
  <div/>

css

.register {
          min-height : calc(100vh - 10rem);
  }

.footer {
         height: 10rem;
 }

Dont need to use position fixed and absolute. Just write the html in proper way.

My issue was with multiple targets. I solved it with below links: configure pod file right way and fix build settings

Hope some one will find it helpful.

[ Solution ]

$ git push origin

^ this solved it for me. What it did, it synchronized my master (on laptop) with "origin" that's on the remote server.

Also this happens when I was installing mysqlclient,

$ pip install mysqlclient

As user3429036 said,

$ brew install mysql

List last updated on December 1, 2020:

As of November 30, 2020, AWS now has EC2 Mac instances:

• https://aws.amazon.com/ec2/instance-types/mac/

We previously used and had good experiences with:

• https://MacStadium.com/

Here are some other sites that I am aware of:

• https://flow.swiss/
• https://hostmyapple.com/ (We used them a long time ago, before MacStadium)
• https://macincloud.com/
• https://macminivault.com/
• https://macweb.com/
• https://virtualmacosx.com/
• https://xcloud.me/
• https://zeromac.com/
• http://www.cloud4mac.com/ 404 as of July, 2014
• https://www.macminicloud.net/ (Redirects to macweb.com)
• https://xcloud.me/ (Redirects to flow.swiss)

When we were with MacStadium, we loved them. We had great connectivity/uptime. When I've needed hands-on support to plug in a Time Machine backup, they've been great. They performed a seamless upgrade to better hardware for us over one weekend (when we could afford a bit of downtime), and that went off without a hitch. Highly recommended. (Not affiliated - just happy).

In April of 2020, we stopped using MacStadium, simply because we no longer needed a Mac server. If I need another Mac host, I would be happy to go back to them.

Initial setup:

var once = function( once_fn ) {
    var ret, is_called;
    // return new function which is our control function 
    // to make sure once_fn is only called once:
    return function(arg1, arg2, arg3) {
        if ( is_called ) return ret;
        is_called = true;
        // return the result from once_fn and store to so we can return it multiply times:
        // you might wanna look at Function.prototype.apply:
        ret = once_fn(arg1, arg2, arg3);
        return ret;
    };
}

refer the above link for more details on Cross domain resource sharing.

you can try using JSONP . If the API is not supporting jsonp, you have to create a service which acts as a middleman between the API and your client. In my case, i have created a asmx service.

sample below:

ajax call:

$(document).ready(function () {
        $.ajax({
            crossDomain: true,
            type:"GET",
            contentType: "application/json; charset=utf-8",
            async:false,
            url: "<your middle man service url here>/GetQuote?callback=?",
            data: { symbol: 'ctsh' },
            dataType: "jsonp",                
            jsonpCallback: 'fnsuccesscallback'
        });
    });

service (asmx) which will return jsonp:

[WebMethod]
    [ScriptMethod(UseHttpGet = true, ResponseFormat = ResponseFormat.Json)]
    public void GetQuote(String symbol,string callback)
    {          

        WebProxy myProxy = new WebProxy("<proxy url here>", true);

        myProxy.Credentials = new System.Net.NetworkCredential("username", "password", "domain");
        StockQuoteProxy.StockQuote SQ = new StockQuoteProxy.StockQuote();
        SQ.Proxy = myProxy;
        String result = SQ.GetQuote(symbol);
        StringBuilder sb = new StringBuilder();
        JavaScriptSerializer js = new JavaScriptSerializer();
        sb.Append(callback + "(");
        sb.Append(js.Serialize(result));
        sb.Append(");");
        Context.Response.Clear();
        Context.Response.ContentType = "application/json";
        Context.Response.Write(sb.ToString());
        Context.Response.End();         
    }

I have used text/comma-separated-values for CSV mime-type in accept attribute and it works fine in Opera. Tried text/csv without luck.

Some others MIME-Types for CSV if the suggested do not work:

• text/comma-separated-values
• text/csv
• application/csv
• application/excel
• application/vnd.ms-excel
• application/vnd.msexcel
• text/anytext

Because the URL isn't on the same domain as your website, you need to use JSONP.

For example: (In jQuery):

$.getJSON(
    'http://soundcloud.com/oembed?url=http%3A//soundcloud.com/forss/flickermood&format=js&callback=?', 
    function(data) { ... }
);

This works by creating a <script> tag like this one:

<script src="http://soundcloud.com/oembed?url=http%3A//soundcloud.com/forss/flickermood&format=js&callback=someFunction" type="text/javascript"></script>

Their server then emits Javascript that calls someFunction with the data to retrieve.
`someFunction is an internal callback generated by jQuery that then calls your callback.

in my case the fix was replacing

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>

with

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>

You should have a 'skeleton' somewhere in /etc, probably /etc/skeleton, or check the default settings, probably /etc/default or something. Those are scripts that define standard environment variables getting set during a login.

If it is just for your own account: check the (hidden) file ~/.profile and ~/.login. Or generate them, if they don't exist. These are also evaluated by the login process.

This would be easier to do with flexbox. Using flexbox will let you not to specify the height of your content and can adjust automatically on the height it contains.

DEMO

here's the gist of the demo

.container{

  display: flex;
  height: 100%;
  justify-content: center;
  align-items: center;

}

html

<div class="container">
  <div class='content'> //you can size this anyway you want
    put anything you want here,

Try this in your model:

function order_summary_insert()
    $OrderLines=$this->input->post('orderlines');
    $CustomerName=$this->input->post('customer');
    $data = array(
        'OrderLines'=>$OrderLines,
        'CustomerName'=>$CustomerName
    );

    $this->db->insert('Customer_Orders',$data);
}

Try to use controller just to control the view and models always post your values in model. it makes easy to understand. Your controller will be:

function new_blank_order_summary() {
    $this->sales_model->order_summary_insert($data);
    $this->load->view('sales/new_blank_order_summary');
}

The one thing to keep in mind about unit testing is that it's a comfort for the developer.

In contrast, functional tests are for the users: whenever you add a functional test, you are testing something that the user will see. When you add a unit test, you are just making your life easier as a developer. It's a little bit of a luxury in that respect.

Keep this dichotomy in mind when you have to make a choice between writing a unit or a functional test.

The question, is the provided example just an "example" or exact what you looking for? There are many mixed answers here, and I dont understand the complexibility of the accepted one.

To find out if ANY content of the array of needles exists in the string, and quickly return true or false:

$string = 'abcdefg';

if(str_replace(array('a', 'c', 'd'), '', $string) != $string){
    echo 'at least one of the needles where found';
};

If, so, please give @Leon credit for that.

To find out if ALL values of the array of needles exists in the string, as in this case, all three 'a', 'b' and 'c' MUST be present, like you mention as your "for example"

echo 'All the letters are found in the string!';

Many answers here is out of that context, but I doubt that the intension of the question as you marked as resolved. E.g. The accepted answer is a needle of

$array  = array('burger', 'melon', 'cheese', 'milk');

What if all those words MUST be found in the string?

Then you try out some "not accepted answers" on this page.

This hasn't solved my problem too, so I changed the parameters slightly.
This code worked for me:

var dataValue = "{ name: 'person', isGoing: 'true', returnAddress: 'returnEmail' }";

$.ajax({
    type: "POST",
    url: "Default.aspx/OnSubmit",
    data: dataValue,
    contentType: 'application/json; charset=utf-8',
    dataType: 'json',
    error: function (XMLHttpRequest, textStatus, errorThrown) {
        alert("Request: " + XMLHttpRequest.toString() + "\n\nStatus: " + textStatus + "\n\nError: " + errorThrown);
    },
    success: function (result) {
        alert("We returned: " + result.d);
    }
});

I tested running a bare-bone, Swift-based app on an iPod Touch (3rd gen) device. It appears Swift-based apps don't work with iOS 5.x but do work with iOS 6.x.

Here's what shows up in the debug log when I tried to launch the test app with iOS 5.0.1:

For iOS 6.1.6, the app runs fine without displaying those error messages.

You get this error because you let a .NET exception happen on your server side, and you didn't catch and handle it, and didn't convert it to a SOAP fault, either.

Now since the server side "bombed" out, the WCF runtime has "faulted" the channel - e.g. the communication link between the client and the server is unusable - after all, it looks like your server just blew up, so you cannot communicate with it any more.

So what you need to do is:

• always catch and handle your server-side errors - do not let .NET exceptions travel from the server to the client - always wrap those into interoperable SOAP faults. Check out the WCF IErrorHandler interface and implement it on the server side

• if you're about to send a second message onto your channel from the client, make sure the channel is not in the faulted state:

  if(client.InnerChannel.State != System.ServiceModel.CommunicationState.Faulted)
  {
     // call service - everything's fine
  }
  else
  {
     // channel faulted - re-create your client and then try again
  }
  

  If it is, all you can do is dispose of it and re-create the client side proxy again and then try again

Does this get the correct answer?

Static cast

char c = 10;       // 1 byte
int *p = (int*)&c; // 4 bytes

Since this results in a 4-byte pointer pointing to 1 byte of allocated memory, writing to this pointer will either cause a run-time error or will overwrite some adjacent memory.

*p = 5; // run-time error: stack corruption

In contrast to the C-style cast, the static cast will allow the compiler to check that the pointer and pointee data types are compatible, which allows the programmer to catch this incorrect pointer assignment during compilation.

int *q = static_cast<int*>(&c); // compile-time error

Reinterpret cast

To force the pointer conversion, in the same way as the C-style cast does in the background, the reinterpret cast would be used instead.

int *r = reinterpret_cast<int*>(&c); // forced conversion

This cast handles conversions between certain unrelated types, such as from one pointer type to another incompatible pointer type. It will simply perform a binary copy of the data without altering the underlying bit pattern. Note that the result of such a low-level operation is system-specific and therefore not portable. It should be used with caution if it cannot be avoided altogether.

Dynamic cast

This one is only used to convert object pointers and object references into other pointer or reference types in the inheritance hierarchy. It is the only cast that makes sure that the object pointed to can be converted, by performing a run-time check that the pointer refers to a complete object of the destination type. For this run-time check to be possible the object must be polymorphic. That is, the class must define or inherit at least one virtual function. This is because the compiler will only generate the needed run-time type information for such objects.

Dynamic cast examples

In the example below, a MyChild pointer is converted into a MyBase pointer using a dynamic cast. This derived-to-base conversion succeeds, because the Child object includes a complete Base object.

class MyBase 
{ 
  public:
  virtual void test() {}
};
class MyChild : public MyBase {};



int main()
{
  MyChild *child = new MyChild();
  MyBase  *base = dynamic_cast<MyBase*>(child); // ok
}

The next example attempts to convert a MyBase pointer to a MyChild pointer. Since the Base object does not contain a complete Child object this pointer conversion will fail. To indicate this, the dynamic cast returns a null pointer. This gives a convenient way to check whether or not a conversion has succeeded during run-time.

MyBase  *base = new MyBase();
MyChild *child = dynamic_cast<MyChild*>(base);

 
if (child == 0) 
std::cout << "Null pointer returned";

If a reference is converted instead of a pointer, the dynamic cast will then fail by throwing a bad_cast exception. This needs to be handled using a try-catch statement.

#include <exception>
// …  
try
{ 
  MyChild &child = dynamic_cast<MyChild&>(*base);
}
catch(std::bad_cast &e) 
{ 
  std::cout << e.what(); // bad dynamic_cast
}

Dynamic or static cast

The advantage of using a dynamic cast is that it allows the programmer to check whether or not a conversion has succeeded during run-time. The disadvantage is that there is a performance overhead associated with doing this check. For this reason using a static cast would have been preferable in the first example, because a derived-to-base conversion will never fail.

MyBase *base = static_cast<MyBase*>(child); // ok

However, in the second example the conversion may either succeed or fail. It will fail if the MyBase object contains a MyBase instance and it will succeed if it contains a MyChild instance. In some situations this may not be known until run-time. When this is the case dynamic cast is a better choice than static cast.

// Succeeds for a MyChild object
MyChild *child = dynamic_cast<MyChild*>(base);

If the base-to-derived conversion had been performed using a static cast instead of a dynamic cast the conversion would not have failed. It would have returned a pointer that referred to an incomplete object. Dereferencing such a pointer can lead to run-time errors.

// Allowed, but invalid
MyChild *child = static_cast<MyChild*>(base);
 
// Incomplete MyChild object dereferenced
(*child);

Const cast

This one is primarily used to add or remove the const modifier of a variable.

const int myConst = 5;
int *nonConst = const_cast<int*>(&myConst); // removes const

Although const cast allows the value of a constant to be changed, doing so is still invalid code that may cause a run-time error. This could occur for example if the constant was located in a section of read-only memory.

*nonConst = 10; // potential run-time error

Const cast is instead used mainly when there is a function that takes a non-constant pointer argument, even though it does not modify the pointee.

void print(int *p) 
{
   std::cout << *p;
}

The function can then be passed a constant variable by using a const cast.

print(&myConst); // error: cannot convert 
                 // const int* to int*
 
print(nonConst); // allowed

Source and More Explanations

Another question elligeable for a 'code-challenge': here are some source code executables to answer the problem, but they are not complete.
Will you find a vb script that anyone can execute on his/her computer, with the expected result ?

systeminfo|find /i "original" 

would give you the actual date... not the number of seconds ;)
As Sammy comments, find /i "install" gives more than you need.
And this only works if the locale is English: It needs to match the language.
For Swedish this would be "ursprungligt" and "ursprüngliches" for German.

In Windows PowerShell script, you could just type:

PS > $os = get-wmiobject win32_operatingsystem
PS > $os.ConvertToDateTime($os.InstallDate) -f "MM/dd/yyyy" 

By using WMI (Windows Management Instrumentation)

If you do not use WMI, you must read then convert the registry value:

PS > $path = 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion'
PS > $id = get-itemproperty -path $path -name InstallDate
PS > $d = get-date -year 1970 -month 1 -day 1 -hour 0 -minute 0 -second 0
## add to hours (GMT offset)
## to get the timezone offset programatically:
## get-date -f zz
PS > ($d.AddSeconds($id.InstallDate)).ToLocalTime().AddHours((get-date -f zz)) -f "MM/dd/yyyy"

The rest of this post gives you other ways to access that same information. Pick your poison ;)

In VB.Net that would give something like:

Dim dtmInstallDate As DateTime
Dim oSearcher As New ManagementObjectSearcher("SELECT * FROM Win32_OperatingSystem")
For Each oMgmtObj As ManagementObject In oSearcher.Get
    dtmInstallDate =
        ManagementDateTimeConverter.ToDateTime(CStr(oMgmtO bj("InstallDate")))
Next

In Autoit (a Windows scripting language), that would be:

;Windows Install Date
;
$readreg = RegRead("HKLM\SOFTWARE\MICROSOFT\WINDOWS NT\CURRENTVERSION\", "InstallDate")
$sNewDate = _DateAdd( 's',$readreg, "1970/01/01 00:00:00")
MsgBox( 4096, "", "Date: " & $sNewDate )
Exit

In Delphy 7, that would go as:

Function GetInstallDate: String;
Var
  di: longint;
  buf: Array [ 0..3 ] Of byte;
Begin
  Result := 'Unknown';
  With TRegistry.Create Do
  Begin
    RootKey := HKEY_LOCAL_MACHINE;
    LazyWrite := True;
    OpenKey ( '\SOFTWARE\Microsoft\Windows NT\CurrentVersion', False );
    di := readbinarydata ( 'InstallDate', buf, sizeof ( buf ) );
//    Result := DateTimeToStr ( FileDateToDateTime ( buf [ 0 ] + buf [ 1 ] * 256 + buf [ 2 ] * 65535 + buf [ 3 ] * 16777216 ) );
showMessage(inttostr(di));
    Free;
  End;
End;

As an alternative, CoastN proposes in the comments:

As the system.ini-file stays untouched in a typical windows deployment, you can actually get the install-date by using the following oneliner:

(PowerShell): (Get-Item "C:\Windows\system.ini").CreationTime

I found the following algorithm provides a very good statistical distribution. Each input bit affects each output bit with about 50% probability. There are no collisions (each input results in a different output). The algorithm is fast except if the CPU doesn't have a built-in integer multiplication unit. C code, assuming int is 32 bit (for Java, replace >> with >>> and remove unsigned):

unsigned int hash(unsigned int x) {
    x = ((x >> 16) ^ x) * 0x45d9f3b;
    x = ((x >> 16) ^ x) * 0x45d9f3b;
    x = (x >> 16) ^ x;
    return x;
}

The magic number was calculated using a special multi-threaded test program that ran for many hours, which calculates the avalanche effect (the number of output bits that change if a single input bit is changed; should be nearly 16 on average), independence of output bit changes (output bits should not depend on each other), and the probability of a change in each output bit if any input bit is changed. The calculated values are better than the 32-bit finalizer used by MurmurHash, and nearly as good (not quite) as when using AES. A slight advantage is that the same constant is used twice (it did make it slightly faster the last time I tested, not sure if it's still the case).

You can reverse the process (get the input value from the hash) if you replace the 0x45d9f3b with 0x119de1f3 (the multiplicative inverse):

unsigned int unhash(unsigned int x) {
    x = ((x >> 16) ^ x) * 0x119de1f3;
    x = ((x >> 16) ^ x) * 0x119de1f3;
    x = (x >> 16) ^ x;
    return x;
}

For 64-bit numbers, I suggest to use the following, even thought it might not be the fastest. This one is based on splitmix64, which seems to be based on the blog article Better Bit Mixing (mix 13).

uint64_t hash(uint64_t x) {
    x = (x ^ (x >> 30)) * UINT64_C(0xbf58476d1ce4e5b9);
    x = (x ^ (x >> 27)) * UINT64_C(0x94d049bb133111eb);
    x = x ^ (x >> 31);
    return x;
}

For Java, use long, add L to the constant, replace >> with >>> and remove unsigned. In this case, reversing is more complicated:

uint64_t unhash(uint64_t x) {
    x = (x ^ (x >> 31) ^ (x >> 62)) * UINT64_C(0x319642b2d24d8ec3);
    x = (x ^ (x >> 27) ^ (x >> 54)) * UINT64_C(0x96de1b173f119089);
    x = x ^ (x >> 30) ^ (x >> 60);
    return x;
}

Update: You may also want to look at the Hash Function Prospector project, where other (possibly better) constants are listed.

Check that your remote host (i.e. the web hosting server you're trying to connect FROM) allows OUTGOING traffic on port 3306.

I saw the (100) error in this situation. I could connect from my PC/Mac, but not from my website. The MySQL instance was accessible via the internet, but my hosting company wasn't allowing my website to connect to the database on port 3306.

Once I asked my hosting company to open my web hosting account up to outgoing traffic on port 3306, my website could connect to my remote database.

Does this mean that you want to add a class to the first button?

$('.o-links').click(function(e) {   // ... }).first().addClass('O_Nav_Current'); 

instead of using IDs for the slider's items and resetting html contents you can use classes and indexes:

CSS:

.image-area {     width: 100%;     height: auto;     display: none; }  .image-area:first-of-type {     display: block; } 

JavaScript:

var $slides = $('.image-area'),     $btns = $('a.o-links');  $btns.on('click', function (e) {     var i = $btns.removeClass('O_Nav_Current').index(this);     $(this).addClass('O_Nav_Current');      $slides.filter(':visible').fadeOut(1000, function () {         $slides.eq(i).fadeIn(1000);     });      e.preventDefault();  }).first().addClass('O_Nav_Current');

You can leverage the java_home helper binary on OS X for what you're looking for.

To list all versions of installed JDK:

$ /usr/libexec/java_home -V
Matching Java Virtual Machines (2):
    1.8.0_51, x86_64:   "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_51.jdk/Contents/Home
    1.7.0_79, x86_64:   "Java SE 7" /Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home

To request the JAVA_HOME path of a specific JDK version, you can do:

$ /usr/libexec/java_home -v 1.7
/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home

$ /usr/libexec/java_home -v 1.8
/Library/Java/JavaVirtualMachines/jdk1.8.0_51.jdk/Contents/Home

You could take advantage of the above commands in your script like this:

REQUESTED_JAVA_VERSION="1.7"
if POSSIBLE_JAVA_HOME="$(/usr/libexec/java_home -v $REQUESTED_JAVA_VERSION 2>/dev/null)"; then
    # Do this if you want to export JAVA_HOME
    export JAVA_HOME="$POSSIBLE_JAVA_HOME"
    echo "Java SDK is installed"
else
    echo "Did not find any installed JDK for version $REQUESTED_JAVA_VERSION"
fi

You might be able to do if-else and check for multiple different versions of java as well.

If you prefer XML output, java_home also has a -X option to output in XML.

This answer concerns developers for Windows. You want to pick an XML parsing module that does NOT depend on node-expat. Node-expat requires node-gyp and node-gyp requires you to install Visual Studio on your machine. If your machine is a Windows Server, you definitely don't want to install Visual Studio on it.

So, which XML parsing module to pick?

Save yourself a lot of trouble and use either xml2js or xmldoc. They depend on sax.js which is a pure Javascript solution that doesn't require node-gyp.

Both libxmljs and xml-stream require node-gyp. Don't pick these unless you already have Visual Studio on your machine installed or you don't mind going down that road.

Update 2015-10-24: it seems somebody found a solution to use node-gyp on Windows without installing VS: https://github.com/nodejs/node-gyp/issues/629#issuecomment-138276692

You will have to define the functions inside your header file.
You cannot separate definition of template functions in to the source file and declarations in to header file.

When a template is used in a way that triggers its intstantation, a compiler needs to see that particular templates definition. This is the reason templates are often defined in the header file in which they are declared.

Reference:
C++03 standard, § 14.7.2.4:

The definition of a non-exported function template, a non-exported member function template, or a non-exported member function or static data member of a class template shall be present in every translation unit in which it is explicitly instantiated.

EDIT:
To clarify the discussion on the comments:
Technically, there are three ways to get around this linking problem:

• To move the definition to the .h file
• Add explicit instantiations in the .cpp file.
• #include the .cpp file defining the template at the .cpp file using the template.

Each of them have their pros and cons,

Moving the defintions to header files may increase the code size(modern day compilers can avoid this) but will increase the compilation time for sure.

Using the explicit instantiation approach is moving back on to traditional macro like approach.Another disadvantage is that it is necessary to know which template types are needed by the program. For a simple program this is easy but for complicated program this becomes difficult to determine in advance.

While including cpp files is confusing at the same time shares the problems of both above approaches.

I find first method the easiest to follow and implement and hence advocte using it.

Using the CLI, to create a functioning NUnit project is really easy. The template does everything for you.

dotnet new -i NUnit3.DotNetNew.Template
dotnet new nunit

On .NET Core, this is definitely my preferred way to go.

It can be very useful a few times, but in general, no fall-through is the desired behavior. Fall-through should be allowed, but not implicit.

An example, to update old versions of some data:

switch (version) {
    case 1:
        // Update some stuff
    case 2:
        // Update more stuff
    case 3:
        // Update even more stuff
    case 4:
        // And so on
}

I added Anaconda3/Library/Bin to the environment path and PyCharm no longer complained with the error.

Yes there is using the following code will allow you to apply a blurring effect to the specified image and also it will allow you to choose the amount of blurring.

img {
  -webkit-filter: blur(10px);
    filter: blur(10px);
}

import java.util.Scanner;

public class LargestSmallestNum {

    public void findLargestSmallestNo() {

        int smallest = Integer.MAX_VALUE;
        int large = 0;
        int num;

        System.out.println("enter the number");

        Scanner input = new Scanner(System.in);

        int n = input.nextInt();

        for (int i = 0; i < n; i++) {

            num = input.nextInt();

            if (num > large)
                large = num;

            if (num < smallest)
                smallest = num;

            System.out.println("the largest is:" + large);
            System.out.println("Smallest no is : "  + smallest);
        }
    }

    public static void main(String...strings){
        LargestSmallestNum largestSmallestNum = new LargestSmallestNum();
        largestSmallestNum.findLargestSmalestNo();
    }
}

This will ensure you get a two-digit day and month.

function formattedDate(d = new Date) {
  let month = String(d.getMonth() + 1);
  let day = String(d.getDate());
  const year = String(d.getFullYear());

  if (month.length < 2) month = '0' + month;
  if (day.length < 2) day = '0' + day;

  return `${day}/${month}/${year}`;
}

Or terser:

function formattedDate(d = new Date) {
  return [d.getDate(), d.getMonth()+1, d.getFullYear()]
      .map(n => n < 10 ? `0${n}` : `${n}`).join('/');
}

I finally discover the error. The problem is that the primary key constraint name is equal the table name. I don know how postgres represents constraints, but I think the error "Relation already exists" was being triggered during the creation of the primary key constraint because the table was already declared. But because of this error, the table wasnt created at the end.

I have added a helper da() to Laravel which in fact works as an alias for dd($object->toArray())

Here is the Gist: https://gist.github.com/TommyZG/0505eb331f240a6324b0527bc588769c

When you "call" a function you are basically just telling the program to execute that function. So if you had a function that added two numbers such as:

def add(a,b):
    return a + b

you would call the function like this:

add(3,5)

which would return 8. You can put any two numbers in the parentheses in this case. You can also call a function like this:

answer = add(4,7)

Which would set the variable answer equal to 11 in this case.

Connection Timeout=30 means that the database server has 30 seconds to establish a connection.

Connection Timeout specifies the time limit (in seconds), within which the connection to the specified server must be made, otherwise an exception is thrown i.e. It specifies how long you will allow your program to be held up while it establishes a database connection.

DataSource=server;
InitialCatalog=database;
UserId=username;
Password=password;
Connection Timeout=30

SqlConnection.ConnectionTimeout. specifies how many seconds the SQL Server service has to respond to a connection attempt. This is always set as part of the connection string.

Notes:

• The value is expressed in seconds, not milliseconds.

• The default value is 30 seconds.

• A value of 0 means to wait indefinitely and never time out.

In addition, SqlCommand.CommandTimeout specifies the timeout value of a specific query running on SQL Server, however this is set via the SqlConnection object/setting (depending on your programming language), and not in the connection string i.e. It specifies how long you will allow your program to be held up while the command is run.

BinaryReader b = new BinaryReader(file.InputStream);
byte[] binData = b.ReadBytes(file.InputStream.Length);

line 2 should be replaced with

byte[] binData = b.ReadBytes(file.ContentLength);

# Title      :  urlencode - encode URL data
# Author     :  Heiner Steven ([email protected])
# Date       :  2000-03-15
# Requires   :  awk
# Categories :  File Conversion, WWW, CGI
# SCCS-Id.   :  @(#) urlencode  1.4 06/10/29
##########################################################################
# Description
#   Encode data according to
#       RFC 1738: "Uniform Resource Locators (URL)" and
#       RFC 1866: "Hypertext Markup Language - 2.0" (HTML)
#
#   This encoding is used i.e. for the MIME type
#   "application/x-www-form-urlencoded"
#
# Notes
#    o  The default behaviour is not to encode the line endings. This
#   may not be what was intended, because the result will be
#   multiple lines of output (which cannot be used in an URL or a
#   HTTP "POST" request). If the desired output should be one
#   line, use the "-l" option.
#
#    o  The "-l" option assumes, that the end-of-line is denoted by
#   the character LF (ASCII 10). This is not true for Windows or
#   Mac systems, where the end of a line is denoted by the two
#   characters CR LF (ASCII 13 10).
#   We use this for symmetry; data processed in the following way:
#       cat | urlencode -l | urldecode -l
#   should (and will) result in the original data
#
#    o  Large lines (or binary files) will break many AWK
#       implementations. If you get the message
#       awk: record `...' too long
#        record number xxx
#   consider using GNU AWK (gawk).
#
#    o  urlencode will always terminate it's output with an EOL
#       character
#
# Thanks to Stefan Brozinski for pointing out a bug related to non-standard
# locales.

OpenSSL provides a passwd command that can encrypt but doesn't decrypt as it only does hashes. You could also download something like aesutil so you can use a capable and well-known symmetric encryption routine.

For example:

#!/bin/sh    
# using aesutil
SALT=$(mkrand 15) # mkrand generates a 15-character random passwd
MYENCPASS="i/b9pkcpQAPy7BzH2JlqHVoJc2mNTBM=" # echo "passwd" | aes -e -b -B -p $SALT 
MYPASS=$(echo "$MYENCPASS" | aes -d -b -p $SALT)

# and usage
serverControl.sh -u admin -p $MYPASS -c shutdown

For completing the answers, Spring MVC uses viewResolver(for example, as axtavt metionned, InternalResourceViewResolver) to get the specific view. Therefore the first step is making sure that a viewResolver is configured.

Secondly, you should pay attention to the url of redirection(redirect or forward). A url starting with "/" means that it's a url absolute in the application. As Jigar says,

return "redirect:/index.html";  

should work. If your view locates in the root of the application, Spring can find it. If a url without a "/", such as that in your question, it means a url relative. It explains why it worked before and don't work now. If your page calling "redirect" locates in the root by chance, it works. If not, Spring can't find the view and it doesn't work.

Here is the source code of the method of RedirectView of Spring

protected void renderMergedOutputModel(  
Map<String, Object> model, HttpServletRequest request, HttpServletResponse response)  
throws IOException {  
  // Prepare target URL.  
  StringBuilder targetUrl = new StringBuilder();  
  if (this.contextRelative && getUrl().startsWith("/")) {  
    // Do not apply context path to relative URLs.  
    targetUrl.append(request.getContextPath());  
  }  
  targetUrl.append(getUrl());  

  // ...  

  sendRedirect(request, response, targetUrl.toString(), this.http10Compatible);  
}  

There are several ways this can be accomplished.

• You can make use of the builtin string function .replace() to replace all occurrences of quotes in a given string:

  >>> s = '"abcd" efgh'
  >>> s.replace('"', '')
  'abcd efgh'
  >>> 
  

• You can use the string function .join() and a generator expression to remove all quotes from a given string:

  >>> s = '"abcd" efgh'
  >>> ''.join(c for c in s if c not in '"')
  'abcd efgh'
  >>> 
  

• You can use a regular expression to remove all quotes from given string. This has the added advantage of letting you have control over when and where a quote should be deleted:

  >>> s = '"abcd" efgh'
  >>> import re
  >>> re.sub('"', '', s)
  'abcd efgh'
  >>> 
  

The XML configuration of Spring is composed of Beans and Beans are basically classes. They're just POJOs that we use inside of our ApplicationContext. Defining Beans can be thought of as replacing the keyword new. So wherever you are using the keyword new in your application something like:

MyRepository myRepository =new MyRepository ();

Where you're using that keyword new that's somewhere you can look at removing that configuration and placing it into an XML file. So we will code like this:

<bean name="myRepository " 
      class="com.demo.repository.MyRepository " />

Now we can simply use Setter Injection/ Constructor Injection. I'm using Setter Injection.

public class MyServiceImpl implements MyService {
    private MyRepository myRepository;
    public void setMyRepository(MyRepository myRepository)
        {
    this.myRepository = myRepository ;
        }
public List<Customer> findAll() {
        return myRepository.findAll();
    }
}

Like a lot of functions, this one can be used in many different ways to solve many different problems, I think of it as yet another tool in our toolbelts.

So far, the discussion has focused heavily on simply hiding an ID, but that is only one value, why not use it for lots of values! That is what I am doing, I use it to load up the values in a class only one view at a time, because html.beginform creates a new object and if your model object for that view already had some values passed to it, those values will be lost unless you provide a reference to those values in the beginform.

To see a great motivation for the html.hiddenfor, I recommend you see Passing data from a View to a Controller in .NET MVC - "@model" not highlighting

You can just display both the text and image as inline-blocks so that they dont stack. using floats like pull-left/pull-right can cause undesired issues so they should be used sparingly

<a class="navbar-brand" href="#">
  <img src="mylogo.png" style="display: inline-block;">
  <span style="display: inline-block;">My Company</span>
</a>

.git/HEAD contains the path of the current ref, the working directory is using as HEAD.

Try setting the charset on your Content-Type:

httpCon.setRequestProperty( "Content-Type", "multipart/form-data; charset=UTF-8; boundary=" + boundary );

Create two animation xml under res/anim folder

slide_down.xml

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

<translate
    android:duration="1000"
    android:fromYDelta="0"
    android:toYDelta="100%" />
</set>

slide_up.xml

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

<translate
    android:duration="1000"
    android:fromYDelta="100%"
    android:toYDelta="0" />
</set>

Load animation Like bellow Code and start animation when you want According to your Requirement

//Load animation 
Animation slide_down = AnimationUtils.loadAnimation(getApplicationContext(),
            R.anim.slide_down);

Animation slide_up = AnimationUtils.loadAnimation(getApplicationContext(),
            R.anim.slide_up);

// Start animation
linear_layout.startAnimation(slide_down); 

If you are using WordPress (as is the case with the OP), you can use the selected function.

<form method="get" action="">
  <select name="name">
    <option value="a" <?php selected( isset($_POST['name']) ? $_POST['name'] : '', 'a' ); ?>>a</option>
    <option value="b" <?php selected( isset($_POST['name']) ? $_POST['name'] : '', 'b' ); ?>>b</option>
  </select>
  <select name="location">
    <option value="x" <?php selected( isset($_POST['location']) ? $_POST['location'] : '', 'x' ); ?>>x</option>
    <option value="y" <?php selected( isset($_POST['location']) ? $_POST['location'] : '', 'y' ); ?>>y</option>
  </select>
  <input type="submit" value="Submit" class="submit" />
</form>

The underscore usually means a C module (i.e. DLL), and Python can't find it. Did you build python yourself? If so, you need to include SSL support.
