We can also use RxJava (very powerful reactive extension library)

Observable.from(persons).distinct(Person::getName)

or

Observable.from(persons).distinct(p -> p.getName())

There's another thread elsewhere on Stack with a similar topic and the best solution I've come across is to use the free version of Helicon Ape

Once you've got that installed, follow the steps at the page Titled "HTTP Authentication and Authorization"

Easy to read? Below is an alternative. It ignores symlinks

#!/bin/bash
currentDir=$(
  cd $(dirname "$0")
  pwd
)

echo -n "current "
pwd
echo script $currentDir

Since I posted the above answer a couple years ago, I've evolved my practice to using this linux specific paradigm, which properly handles symlinks:

ORIGIN=$(dirname $(readlink -f $0))

If after"git push origin master" command u see the error "could not read from remote repository" then try this out

1.ssh-keygen -t rsa -b 4096 -C "youremail"
2.eval $(ssh-agent -s)
3.ssh-add ~/.ssh/id_rsa
4.clip < ~/.ssh/id_rsa.pub(it copies the ssh key that has got generated)
5.then go to your remote repository on github and goto settings-> SSH and GPG keys ->new SSH key ->enter any title and paste the copied SSH key and save it
6. now give git push origin master

I think, from your description, the following would suffice:

DELETE FROM guide_category 
WHERE id_guide NOT IN (SELECT id_guide FROM guide)

I assume, that there are no referential integrity constraints on the tables involved, are there?

I found this blog post which cleared up a few things. To quote the most relevant bit:

Mixed Active Content is now blocked by default in Firefox 23!

What is Mixed Content?
When a user visits a page served over HTTP, their connection is open for eavesdropping and man-in-the-middle (MITM) attacks. When a user visits a page served over HTTPS, their connection with the web server is authenticated and encrypted with SSL and hence safeguarded from eavesdroppers and MITM attacks.

However, if an HTTPS page includes HTTP content, the HTTP portion can be read or modified by attackers, even though the main page is served over HTTPS. When an HTTPS page has HTTP content, we call that content “mixed”. The webpage that the user is visiting is only partially encrypted, since some of the content is retrieved unencrypted over HTTP. The Mixed Content Blocker blocks certain HTTP requests on HTTPS pages.

The resolution, in my case, was to simply ensure the jquery includes were as follows (note the removal of the protocol):

<link rel="stylesheet" href="//code.jquery.com/ui/1.8.10/themes/smoothness/jquery-ui.css" type="text/css">
<script type="text/javascript" src="//ajax.aspnetcdn.com/ajax/jquery.ui/1.8.10/jquery-ui.min.js"></script>

Note that the temporary 'fix' is to click on the 'shield' icon in the top-left corner of the address bar and select 'Disable Protection on This Page', although this is not recommended for obvious reasons.

UPDATE: This link from the Firefox (Mozilla) support pages is also useful in explaining what constitutes mixed content and, as given in the above paragraph, does actually provide details of how to display the page regardless:

Most websites will continue to work normally without any action on your part.

If you need to allow the mixed content to be displayed, you can do that easily:

Click the shield icon Mixed Content Shield in the address bar and choose Disable Protection on This Page from the dropdown menu.

The icon in the address bar will change to an orange warning triangle Warning Identity Icon to remind you that insecure content is being displayed.

To revert the previous action (re-block mixed content), just reload the page.

Adding additional information to emboss's answer.

To put it simply, there is an incorrect cert in your certificate chain.

For example, your certificate authority will have most likely given you 3 files.

• your_domain_name.crt
• DigiCertCA.crt # (Or whatever the name of your certificate authority is)
• TrustedRoot.crt

You most likely combined all of these files into one bundle.

-----BEGIN CERTIFICATE----- 
(Your Primary SSL certificate: your_domain_name.crt) 
-----END CERTIFICATE----- 
-----BEGIN CERTIFICATE----- 
(Your Intermediate certificate: DigiCertCA.crt) 
-----END CERTIFICATE----- 
-----BEGIN CERTIFICATE----- 
(Your Root certificate: TrustedRoot.crt) 
-----END CERTIFICATE-----

If you create the bundle, but use an old, or an incorrect version of your Intermediate Cert (DigiCertCA.crt in my example), you will get the exact symptoms you are describing.

• SSL connections appear to work from browser
• SSL connections fail from other clients
• Curl fails with error: "curl: (60) SSL certificate : unable to get local issuer certificate"
• openssl s_client -connect gives error "verify error:num=20:unable to get local issuer certificate"

Redownload all certs from your certificate authority and make a fresh bundle.

I suggest you to use LinkedHashSet most of the time, because it has better performance overall):

1. Predictable iteration order LinkedHashSet (Oracle)
2. LinkedHashSet is more expensive for insertions than HashSet;
3. In general slightly better performance than HashMap, because the most of the time we use Set structures for iterating.

Performance tests:

------------- TreeSet -------------
 size       add  contains   iterate
   10       746       173        89
  100       501       264        68
 1000       714       410        69

It has happened to me that it stayed stuck in "Waiting for Debugger" when accidentally I tried to Debug a Release build, sometimes it warns that it is not a debug build and others it silently stucks in "Waiting for Debugger".

The solution is obviously to switch to Debug build

this website shows several formatting options.

Example:

SELECT CONVERT(VARCHAR(10), GETDATE(), 105) 

I don't believe there is one.

bool is just an alias for System.Boolean

Here you can find some public REST services for encryption and security related things: http://security.jelastic.servint.net

In case, you added a box and started downloading it but interrupted that download, go to ~/.vagrant.d/tmp/ and delete the partial download file, then try again.

You could use an extension method to get notified about changed property of an item in a collection in a generic way.

public static class ObservableCollectionExtension
{
    public static void NotifyPropertyChanged<T>(this ObservableCollection<T> observableCollection, Action<T, PropertyChangedEventArgs> callBackAction)
        where T : INotifyPropertyChanged
    {
        observableCollection.CollectionChanged += (sender, args) =>
        {
            //Does not prevent garbage collection says: http://stackoverflow.com/questions/298261/do-event-handlers-stop-garbage-collection-from-occuring
            //publisher.SomeEvent += target.SomeHandler;
            //then "publisher" will keep "target" alive, but "target" will not keep "publisher" alive.
            if (args.NewItems == null) return;
            foreach (T item in args.NewItems)
            {
                item.PropertyChanged += (obj, eventArgs) =>
                {
                    callBackAction((T)obj, eventArgs);
                };
            }
        };
    }
}

public void ExampleUsage()
{
    var myObservableCollection = new ObservableCollection<MyTypeWithNotifyPropertyChanged>();
    myObservableCollection.NotifyPropertyChanged((obj, notifyPropertyChangedEventArgs) =>
    {
        //DO here what you want when a property of an item in the collection has changed.
    });
}

This works for me

var dataTable = $('#HelpdeskOverview').dataTable();

var oSettings = dataTable.fnSettings();
dataTable.fnClearTable(this);
for (var i=0; i<json.aaData.length; i++)
{
   dataTable.oApi._fnAddData(oSettings, json.aaData[i]);
}
oSettings.aiDisplay = oSettings.aiDisplayMaster.slice();
dataTable.fnDraw();

If you use Python 3.6 (possibly 3.5 or later), it doesn't give that error to me anymore. I had a similar issue, because I was using v3.4, but it went away after I uninstalled and reinstalled.

If rendering performance is critical, you might also want to look at yajl-ruby, which is a binding to the C yajl library. The serialization API for that one looks like:

require 'yajl'
Yajl::Encoder.encode({"foo" => "bar"}) #=> "{\"foo\":\"bar\"}"

For the 5.7 version, I had the same problem and a simple fix did the trick. As Installed the workbench 5.7 there was another "software" of sorts called the "MySQL Installer Community". I ran this and ran the "Reconfigure" for the MySQL server. It took about a minute and the problem was no longer there.

Hope it works!.(Keep in mind i was using the 5.7 version)

I use this little PowerShell snippet:

function Get-SystemUptime {
    $operatingSystem = Get-WmiObject Win32_OperatingSystem
    "$((Get-Date) - ([Management.ManagementDateTimeConverter]::ToDateTime($operatingSystem.LastBootUpTime)))"
}

which then yields something like the following:

PS> Get-SystemUptime
6.20:40:40.2625526

If the DC is Win2k3 SP2 or above, you can use something like:

(&(objectCategory=user)(memberOf:1.2.840.113556.1.4.1941:=CN=GroupOne,OU=Security Groups,OU=Groups,DC=example,DC=com))

to get the nested group membership.

You can use np.concatenate() specifying which axis to append, using np.newaxis:

import numpy as np
movie = np.concatenate((img1[:,np.newaxis], img2[:,np.newaxis]), axis=3)

If you are reading from many files:

import glob
movie = np.concatenate([cv2.imread(p)[:,np.newaxis] for p in glob.glob('*.jpg')], axis=3)

UPDATE: This does not directly answer the question in its entirety, but others may find this useful.

This is the HTML for your responsive footer

<footer class="footer navbar-fixed-bottom">
     <div class="container">
     </div>
</footer>

For the CSS

footer{
    width:100%;
    min-height:100px;    
    background-color: #222; /* This color gets inverted color or you can add navbar inverse class in html */
}

NOTE: At the time of the posting for this question the above lines of code does not push the footer below the page content; but it will keep your footer from crawling midway up the page when there is little content on the page. For an example that does push the footer below the page content take a look here http://getbootstrap.com/examples/sticky-footer/

goto command prompt

netstat -aon

check which process has binded your port. here in above example its 248 now if you are sure that you need to kill that process fire

Linux:

kill -9 248

Windows:

taskkill /f /pid 248

it will kill that process

In conf directory of apache tomcat you can find context.xml file. In that edit tag as <Context reloadable="true">. this should solve the issue and you need not restart the server

1. Go to File -> Source Control -> Advanced -> Change Source Control (if change source control doesn't appear, click on solution in the solution explorer then try again)
2. Unbind solution and all projects

Now right click on solution and you will see "Add Project To Source Control". if you want to add project to source control again you might be get some errors that ask you to change the solution folder on TFS. it happens because your solution has some mapping in a workspace yet. remove mapping or delete workspace. now your solution is completely unbind and unmapped from TFS or workspaces.

Updated answer, from Peter in comments :

This is de "old terminology", use directally the WSDL2 "endepoint" definition (WSDL2 translated "port" to "endpoint").

Maybe you find an answer in this document : http://www.w3.org/TR/wsdl.html

A WSDL document defines services as collections of network endpoints, or ports. In WSDL, the abstract definition of endpoints and messages is separated from their concrete network deployment or data format bindings. This allows the reuse of abstract definitions: messages, which are abstract descriptions of the data being exchanged, and port types which are abstract collections of operations. The concrete protocol and data format specifications for a particular port type constitutes a reusable binding. A port is defined by associating a network address with a reusable binding, and a collection of ports define a service. Hence, a WSDL document uses the following elements in the definition of network services:

• Types– a container for data type definitions using some type system (such as XSD).
• Message– an abstract, typed definition of the data being communicated.
• Operation– an abstract description of an action supported by the service.
• Port Type–an abstract set of operations supported by one or more endpoints.
• Binding– a concrete protocol and data format specification for a particular port type.
• Port– a single endpoint defined as a combination of a binding and a network address.
• Service– a collection of related endpoints.

http://www.ehow.com/info_12212371_definition-service-endpoint.html

The endpoint is a connection point where HTML files or active server pages are exposed. Endpoints provide information needed to address a Web service endpoint. The endpoint provides a reference or specification that is used to define a group or family of message addressing properties and give end-to-end message characteristics, such as references for the source and destination of endpoints, and the identity of messages to allow for uniform addressing of "independent" messages. The endpoint can be a PC, PDA, or point-of-sale terminal.

Your Ubuntu definitely has a sufficiently recent version of g++. The flag to use is -std=c++0x.

Use the built in functions:

SELECT URLX, COUNT(URLx) AS Count
FROM ExternalHits
WHERE datex BETWEEN DATE_SUB(NOW(), INTERVAL 7 DAY) AND NOW()
GROUP BY URLx
ORDER BY Count DESC; 

I ended up using this handy macro:

#define STRING(value)               [@(value) stringValue]

Stopping the container didn't work for me either. I changed the port in docker-compose.yml.

Surely you just need:

double seconds = milliseconds / 1000.0;

There's no need to manually do the two parts separately - you just need floating point arithmetic, which the use of 1000.0 (as a double literal) forces. (I'm assuming your milliseconds value is an integer of some form.)

Note that as usual with double, you may not be able to represent the result exactly. Consider using BigDecimal if you want to represent 100ms as 0.1 seconds exactly. (Given that it's a physical quantity, and the 100ms wouldn't be exact in the first place, a double is probably appropriate, but...)

Getting the second largest number from an array is pretty easy in python, I have done with simple steps and put various ways of test cases and it gave the right answer every time. PS. I know it's for c but I just gave a simple solution to the question if done in python

n = int(input()) #taking number of elements in array
arr = map(int, input().split()) #taking differet elements
l=[]
s=set()
for i in arr: #putting all the elemnents in set to remove any duplicate number
    s.add(i)
for j in s:  #putting all element from the set in the list to sort and get the second largest number
    l.append(j)
l.sort()
c=len(l)
print(l[c-2]) #printing second largest number

(In addition of the official "GitHub Help 'Using pull requests' page",
see also "Forking vs. Branching in GitHub", "What is the difference between origin and upstream in GitHub")

Couple tips on pull-requests:

Assuming that you have first forked a repo, here is what you should do in that fork that you own:

• create a branch: isolate your modifications in a branch. Don't create a pull request from master, where you could be tempted to accumulate and mix several modifications at once.
• rebase that branch: even if you already did a pull request from that branch, rebasing it on top of origin/master (making sure your patch is still working) will update the pull request automagically (no need to click on anything)
• update that branch: if your pull request is rejected, you simply can add new commits, and/or redo your history completely: it will activate your existing pull request again.
• "focus" that branch: i.e., make its topic "tight", don't modify thousands of class and the all app, only add or fix a well-defined feature, keeping the changes small.
• delete that branch: once accepted, you can safely delete that branch on your fork (and git remote prune origin). The GitHub GUI will propose for you to delete your branch in your pull-request page.

Note: to write the Pull-Request itself, see "How to write the perfect pull request" (January 2015, GitHub)

March 2016: New PR merge button option: see "Github squash commits from web interface on pull request after review comments?".

The maintainer of the repo can chose to merge --squash those PR commits.

After a Pull Request

Regarding the last point, since April, 10th 2013, "Redesigned merge button", the branch is deleted for you:

Deleting branches after you merge has also been simplified.
Instead of confirming the delete with an extra step, we immediately remove the branch when you delete it and provide a convenient link to restore the branch in the event you need it again.

That confirms the best practice of deleting the branch after merging a pull request.

pull-request vs. request-pull

• pull request isn't an official "git" term.
  Git uses the request-pull(!) command to build a request for merging:
  It "summarizes the changes between two commits to the standard output, and includes the given URL in the generated summary."
  Github launches its own version since day one (February 2008), but redesigned that feature in May 2010, stating that:

  Pull Request = Compare View + Issues + Commit comments
  

e-notes for "reposotory" (sic)

<humour>

That (pull request) isn't even defined properly by GitHub!

Fortunately, a true business news organization would know, and there is an e-note in order to replace pull-replace by 'e-note':

So if your reposotory needs a e-note... ask Fox Business. They are in the know.

</humour>

Yes. The casts are redundant. In your expression:

true == 1

Integral promotion applies and the bool value will be promoted to an int and this promotion must yield 1.

Reference: 4.7 [conv.integral] / 4: If the source type is bool... true is converted to one.

Here you can see what (mobile) browsers support css position fixed + there version.

How about:

find . -name '*.h' -o -name '*.cpp' -exec grep "CP_Image" {} \; -print

Pretty much. One small difference though: if the Task fails, GetResult() will just throw the exception caused directly, while Task.Result will throw an AggregateException. However, what's the point of using either of those when it's async? The 100x better option is to use await.

Also, you're not meant to use GetResult(). It's meant to be for compiler use only, not for you. But if you don't want the annoying AggregateException, use it.

I have always taken it to mean absent. Here are four cases in the C language that matches to this use of absent

• R f(void) - Function parameters are absent
• void f(P) - Return value is absent
• void *p - Type of what is pointed to is absent
• (void) p - Usage of value is absent

Other C descendants use it for other things. The D programming language uses it for cases where an initializer is absent

• T t = void; - initializing value is absent

This is very late, but I thought it could be useful to someone should they reference this question. I beleive the below JS will do what is asked.

<script>     
         $(document).ready(function()
           {
          document.getElementById('select').size=3;
           });
    </script> 

A POJO is a Plain Old Java Object.

From the wikipedia article I linked to:

In computing software, POJO is an acronym for Plain Old Java Object. The name is used to emphasize that a given object is an ordinary Java Object, not a special object, and in particular not an Enterprise JavaBean

Your class appears to already be a POJO.

You have just created an empty integer array. The array guess does not contain anything to my knowledge. The rest you should work out to get better.

Join the table with itself and give it two different aliases (A and B in the following example). This allows to compare different rows of the same table.

SELECT DISTINCT A.Id
FROM
    Address A
    INNER JOIN Address B
        ON A.Id = B.Id AND A.[Adress Code] < B.[Adress Code]
WHERE
    A.Address <> B.Address

The "less than" comparison < ensures that you get 2 different addresses and you don't get the same 2 address codes twice. Using "not equal" <> instead, would yield the codes as (1, 2) and (2, 1); each one of them for the A alias and the B alias in turn.

The join clause is responsible for the pairing of the rows where as the where-clause tests additional conditions.

The query above works with any address codes. If you want to compare addresses with specific address codes, you can change the query to

SELECT A.Id
FROM
    Address A
    INNER JOIN Address B
        ON A.Id = B.Id
WHERE                     
    A.[Adress Code] = 1 AND
    B.[Adress Code] = 2 AND
    A.Address <> B.Address

I imagine that this might be useful to find customers having a billing address (Adress Code = 1 as an example) differing from the delivery address (Adress Code = 2) .

Since nobody mentioned it yet, you can compare arrays with the std::equal algorithm:

int iar1[] = {1,2,3,4,5};
int iar2[] = {1,2,3,4,5};

if (std::equal(std::begin(iar1), std::end(iar1), std::begin(iar2)))
    cout << "Arrays are equal.";
else
    cout << "Arrays are not equal.";

You need to include <algorithm> and <iterator>. If you don't use C++11 yet, you can write:

if (std::equal(iar1, iar1 + sizeof iar1 / sizeof *iar1, iar2))

If you don't want to create a new primary key you can use the TOP command in SQL Server:

declare @ID int
while EXISTS(select count(*) from Employee group by EmpId having count(*)> 1)
begin
    select top 1 @ID = EmpId
    from Employee 
    group by EmpId
    having count(*) > 1

    DELETE TOP(1) FROM Employee WHERE EmpId = @ID
end

Implement onFocusChange of setOnFocusChangeListener and there's a boolean parameter for hasFocus. When this is false, you've lost focus to another control.

 EditText txtEdit = (EditText) findViewById(R.id.edittxt);

 txtEdit.setOnFocusChangeListener(new OnFocusChangeListener() {          
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (!hasFocus) {
               // code to execute when EditText loses focus
            }
        }
    });

How about mkString ?

theStrings.mkString(",")

A variant exists in which you can specify a prefix and suffix too.

See here for an implementation using foldLeft, which is much more verbose, but perhaps worth looking at for education's sake.

Adding on to the top answer you can also use views with a dark gray background color in a Linear Layout like so.

<View
    android:layout_width="match_parent"
    android:layout_height="1dip"
    android:layout_marginBottom="4dip"
    android:layout_marginLeft="4dip"
    android:layout_marginRight="4dip"
    android:layout_marginTop="4dip"
    android:background="@android:color/darker_gray"/>

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginBottom="4dip"
    android:orientation="horizontal"
    android:weightSum="1">

    <Button
        android:id="@+id/button_decline"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dp"
        android:layout_weight="0.50"
        android:background="?android:attr/selectableItemBackground"
        android:padding="10dip"
        android:text="@string/decline"/>

    <View
        android:layout_width="1dip"
        android:layout_height="match_parent"
        android:layout_marginLeft="4dip"
        android:layout_marginRight="4dip"
        android:background="@android:color/darker_gray"/>

    <Button
        android:id="@+id/button_accept"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginRight="10dp"
        android:layout_weight="0.50"
        android:background="?android:attr/selectableItemBackground"
        android:padding="10dip"
        android:text="@string/accept"/>
</LinearLayout>

If your line is horizontal you'll want to set the height to 1dip and the width to match the parent and vice-versa if your line is vertical.

You can add your own static resource handler (it overwrites the default), e.g.

@Configuration
public class StaticResourceConfiguration extends WebMvcConfigurerAdapter {
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/**").addResourceLocations("file:/path/to/my/dropbox/");
    }
}

There is some documentation about this in Spring Boot, but it's really just a vanilla Spring MVC feature.

Also since spring boot 1.2 (I think) you can simply set spring.resources.staticLocations.

From Android P, defining the READ_PHONE_STATE permission in AndroidManifest only, will not work. We have to actually request for the permission. Below code works for me:

@RequiresApi(api = Build.VERSION_CODES.P)
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_PHONE_STATE}, 101);
    }
}

@RequiresApi(api = Build.VERSION_CODES.O)
@Override
protected void onResume() {
    super.onResume();
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
        return;
    }
    Log.d(TAG,Build.getSerial());
}
@RequiresApi(api = Build.VERSION_CODES.O)
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    switch (requestCode) {
        case 101:
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
                return;
            }
        } else {
            //not granted
        }
        break;
        default:
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }
}

Add this permissions in AndroidManifest.xml

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

Hope this helps.

Thank You, MJ

It is enough to use color property alongside with -webkit-text-fill-color this way:

    input {_x000D_
        color: red; /* color of caret */_x000D_
        -webkit-text-fill-color: black; /* color of text */_x000D_
    }

<input type="text"/>

Works in WebKit browsers (but not in iOS Safari, where is still used system color for caret) and also in Firefox.

The -webkit-text-fill-color CSS property specifies the fill color of characters of text. If this property is not set, the value of the color property is used. MDN

So this means we set text color with text-fill-color and caret color with standard color property. In unsupported browser, caret and text will have same color – color of the caret.

https://www.php.net/manual/en/function.array-merge.php

<?php
$array1 = array("color" => "red", 2, 4);
$array2 = array("a", "b", "color" => "green", "shape" => "trapezoid", 4);
$result = array_merge($array1, $array2);
print_r($result);
?>

A node is defined as:

the smallest unit of a valid, complete structure in a document.

or as:

An object in the tree view that serves as a container to hold related objects.

Now their are many different kinds of nodes as an elements node, an attribute node etc.

Figured this out with the help of a friend. The -m PuTTY option will end your session immediately after it executes the shell file. What I've done instead is I've created a batch script called putty.bat with these contents on my Windows machine:

@echo off
putty -load "host" -l username -pw password

This logs me in remotely to the Linux host. On the host side, I created a shell file called sql with these contents:

#!/bin/tcsh

add oracle10g
sqlplus username password

My host's Linux build used tcsh. Other Linux builds might use bash, so simply replace tcsh with bash and you should be fine.

To summarize, automating these steps are now done in two easy steps:

1. Double-click putty.bat. This opens PuTTY and logs me into the host.
2. Run command tcsh sql. This adds the oracle tool to my host, and logs me into the sql database.

Below Test Init will also do the job.

[TestInitialize]
public void TestInit()
{
  HttpContext.Current = new HttpContext(new HttpRequest(null, "http://tempuri.org", null), new HttpResponse(null));
  YourControllerToBeTestedController = GetYourToBeTestedController();
}

None of the screen commands were killing or reattaching the screen for me. Any screen command would just hang. I found another approach.

Each running screen has a file associated with it in:

/var/run/screen/S-{user_name}

The files in that folder will match the names of the screens when running the screen -list. If you delete the file, it kills the associated running screen (detached or attached).

As seen in Install crontab on CentOS, the crontab package in CentOS is vixie-cron. Hence, do install it with:

yum install vixie-cron

And then start it with:

service crond start

To make it persistent, so that it starts on boot, use:

chkconfig crond on

On CentOS 7 you need to use cronie:

yum install cronie

On CentOS 6 you can install vixie-cron, but the real package is cronie:

yum install vixie-cron

and

yum install cronie

In both cases you get the same output:

No, how you are doing it is correct.

http://www.w3.org/MarkUp/html-spec/html-spec_8.html#SEC8.2.2

Because % is only defined for integer types. That's the modulus operator.

5.6.2 of the standard:

The operands of * and / shall have arithmetic or enumeration type; the operands of % shall have integral or enumeration type. [...]

As Oli pointed out, you can use fmod(). Don't forget to include math.h.

Off the top of my head:

1. Styles - Obj-C is dynamic, C++ is typically static
2. Although they are both OOP, I'm certain the solutions would be different.
3. Different object model (C++ is restricted by its compile-time type system).

To me, the biggest difference is the model system. Obj-C lets you do messaging and introspection, but C++ has the ever-so-powerful templates.

Each have their strengths.

   @Html.TextBoxFor(model => model.IdUsuario, new { @Value = "" + User.Identity.GetUserId() + "", @disabled = "true" })

@disabled = "true"

Work very well

Now you can publish ASP.NET 5 app to Docker on Linux with Visual Studio. See the below post from Scott Haselman

Use onclick="return location.reload();" within the button tag.

<button id="refersh-page" name="refersh-page" type="button" onclick="return location.reload();">Refesh Page</button>

Renee's answer is well explained. Addition to the answer with an example:

Node does a lot of things to your file and one of the important is WRAPPING your file. Inside nodejs source code "module.exports" is returned. Lets take a step back and understand the wrapper. Suppose you have

greet.js

var greet = function () {
   console.log('Hello World');
};

module.exports = greet;

the above code is wrapped as IIFE(Immediately Invoked Function Expression) inside nodejs source code as follows:

(function (exports, require, module, __filename, __dirname) { //add by node

      var greet = function () {
         console.log('Hello World');
      };

      module.exports = greet;

}).apply();                                                  //add by node

return module.exports;                                      //add by node

and the above function is invoked (.apply()) and returned module.exports. At this time module.exports and exports pointing to the same reference.

Now, imagine you re-write greet.js as

exports = function () {
   console.log('Hello World');
};
console.log(exports);
console.log(module.exports);

the output will be

[Function]
{}

the reason is : module.exports is an empty object. We did not set anything to module.exports rather we set exports = function()..... in new greet.js. So, module.exports is empty.

Technically exports and module.exports should point to same reference(thats correct!!). But we use "=" when assigning function().... to exports, which creates another object in the memory. So, module.exports and exports produce different results. When it comes to exports we can't override it.

Now, imagine you re-write (this is called Mutation) greet.js (referring to Renee answer) as

exports.a = function() {
    console.log("Hello");
}

console.log(exports);
console.log(module.exports);

the output will be

{ a: [Function] }
{ a: [Function] }

As you can see module.exports and exports are pointing to same reference which is a function. If you set a property on exports then it will be set on module.exports because in JS, objects are pass by reference.

Conclusion is always use module.exports to avoid confusion. Hope this helps. Happy coding :)

Since at least Spring 3, instead of using UriComponentsBuilder to build the URL (which is a bit verbose), many of the RestTemplate methods accept placeholders in the path for parameters (not just exchange).

From the documentation:

Many of the RestTemplate methods accepts a URI template and URI template variables, either as a String vararg, or as Map<String,String>.

For example with a String vararg:

restTemplate.getForObject(
   "http://example.com/hotels/{hotel}/rooms/{room}", String.class, "42", "21");

Or with a Map<String, String>:

Map<String, String> vars = new HashMap<>();
vars.put("hotel", "42");
vars.put("room", "21");

restTemplate.getForObject("http://example.com/hotels/{hotel}/rooms/{room}", 
    String.class, vars);

Reference: https://docs.spring.io/spring/docs/current/spring-framework-reference/integration.html#rest-resttemplate-uri

If you look at the JavaDoc for RestTemplate and search for "URI Template", you can see which methods you can use placeholders with.

You can use the below code to change the button to Left side.

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:map="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"
    android:layout_height="match_parent"

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        android:text="Send"
        android:padding="10dp"
        android:layout_marginTop="20dp"
        android:paddingRight="10dp"/>

$("**:**input[type=text], :input[type='textarea']").css({width: '90%'});

Here's a gitHub project that does just that.

It records audio from the browser in mp3 format, and it automatically saves it to the webserver. https://github.com/Audior/Recordmp3js

You can also view a detailed explanation of the implementation: http://audior.ec/blog/recording-mp3-using-only-html5-and-javascript-recordmp3-js/

Regarding the first question: What are the scenarios where a process gets a SIGABRT in C++?

I can think of two special cases where a C++ program is aborted automatically -- not by directly calling std::abort() or std::terminate():

One: Throw an exception while an exception is being handled.

try {
    throw "abc";
}
catch (...) {
    throw "def";  // abort here
}

Two: An uncaught exception that attempts to propagates outside main().

int main(int argc, char** argv)
{
    throw "abc";  // abort here
}

C++ experts could probably name more special cases.

There is also a lot of good info on these reference pages:

• https://en.cppreference.com/w/cpp/utility/program/abort
• https://en.cppreference.com/w/cpp/error/terminate

I try a late, but from far sight answer:

If you want to know if values in a (any) hash are set, all above answers a true, depending of their point of view.

If you want to test your (GET/POST..) params, you should use something more special to what you expect to be the value of params[:one], something like

if params[:one]~=/   / and  params[:two]~=/[a-z]xy/

ignoring parameter (GET/POST) as if they where not set, if they dont fit like expected

just a if params[:one] with or without nil/true detection is one step to open your page for hacking, because, it is typically the next step to use something like select ... where params[:one] ..., if this is intended or not, active or within or after a framework.

This acronym might help you to remember the ASP.NET life cycle stages which I wrote about in the below blog post.

R-SIL-VP-RU

1. Request
2. Start
3. Initialization
4. Load
5. Validation
6. Post back handling
7. Rendering
8. Unload

check this as well This gives an overview of associated constraints across a database. Please also include facilitating where condition with table name of interest so gives information faster.

   select 
a.TABLE_CATALOG as DB_name,a.TABLE_SCHEMA as tbl_schema, a.TABLE_NAME as tbl_name,a. CONSTRAINT_NAME as constraint_name,b.CONSTRAINT_TYPE
 from INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE a
join INFORMATION_SCHEMA.TABLE_CONSTRAINTS b on
 a.CONSTRAINT_NAME=b.CONSTRAINT_NAME

In Java, single quotes can only take one character, with escape if necessary. You need to use full quotation marks as follows for strings:

y = "hello";

You also used

System.out.println(g);

which I assume should be

System.out.println(y);

Note: When making char values (you'll likely use them later) you need single quotes. For example:

char foo='m';

Please note that as of 2016, ReCaptcha doesn't naively support localhost anymore. From the FAQ:

localhost domains are no longer supported by default. If you wish to continue supporting them for development you can add them to the list of supported domains for your site key. Go to the admin console to update your list of supported domains. We advise to use a separate key for development and production and to not allow localhost on your production site key.

So just add localhost to your list of domains for your site and you'll be good.

You don't need to escape the ' character in a String (wrapped in "), and you don't have to escape a " character in a char (wrapped in ').

In Storyboard, select your ViewController and go to Atribute Inspector. At the very top, under Simulated Metrics you have Size and Orientation properties which are set to Inferred. Change them to desired values.

In order for an application to display properly on another screen size, you also have to setup constraints, as described by Can Poyrazoglu in the first post.

In general, android:gravity="right" is different from android:layout_gravity="right".

The first one affects the position of the text itself within the View, so if you want it to be right-aligned, then layout_width= should be either "fill_parent" or "match_parent".

The second one affects the View's position inside its parent, in other words - aligning the object itself (edit box or text view) inside the parent view.

You can use the static method Enum.GetNames which returns an array representing the names of all the items in the enum. The length property of this array equals the number of items defined in the enum

var myEnumMemberCount = Enum.GetNames(typeof(MyEnum)).Length;

First of all you missed ScriptService attribute to add in webservice.

[ScriptService]

After then try following method to call webservice via JSON.

        var webAddr = "http://Domain/VBRService.asmx/callJson";
        var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr);
        httpWebRequest.ContentType = "application/json; charset=utf-8";
        httpWebRequest.Method = "POST";            

        using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
        {
            string json = "{\"x\":\"true\"}";

            streamWriter.Write(json);
            streamWriter.Flush();
        }

        var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
        using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
        {
            var result = streamReader.ReadToEnd();
            return result;
        }

Since Express 4.0, there's a dedicated sendStatus function:

res.sendStatus(404);

If you're using an earlier version of Express, use the status function instead.

res.status(404).send('Not found');

The easiest way that I found to recover a lost commit (that only exists on github and not locally) is to create a new branch that includes this commit.

1. Have the commit open (url like: github.com/org/repo/commit/long-commit-sha)
2. Click "Browse Files" on the top right
3. Click the dropdown "Tree: short-sha..." on the top left
4. Type in a new branch name
5. git pull the new branch down to local

Try this:

DateTime Date = DateTime.Now.AddHours(-DateTime.Now.Hour).AddMinutes(-DateTime.Now.Minute)
   .AddSeconds(-DateTime.Now.Second);

Output will be like:

07/29/2015 00:00:00

Use Content Resolver ("content://sms/inbox") to read SMS which are in inbox.

// public static final String INBOX = "content://sms/inbox";
// public static final String SENT = "content://sms/sent";
// public static final String DRAFT = "content://sms/draft";
Cursor cursor = getContentResolver().query(Uri.parse("content://sms/inbox"), null, null, null, null);

if (cursor.moveToFirst()) { // must check the result to prevent exception
    do {
       String msgData = "";
       for(int idx=0;idx<cursor.getColumnCount();idx++)
       {
           msgData += " " + cursor.getColumnName(idx) + ":" + cursor.getString(idx);
       }
       // use msgData
    } while (cursor.moveToNext());
} else {
   // empty box, no SMS
}

Please add READ_SMS permission.

I Hope it helps :)

Note: this no longer works due to https://github.com/Homebrew/brew/pull/612

I had the same problem today. I uninstalled (unbrewed??) openssl 1.0.2 and installed 1.0.1 also with homebrew. Dotnet new/restore/run then worked fine.

It should probably be noted that the for loop is faster than the foreach. So for the original post, if you are worried about performance on a critical component like a renderer, use a for loop.

Reference: In .NET, which loop runs faster, 'for' or 'foreach'?

use below.

from tkinter import *
root=Tk()
.....
root.mainloop()

Ah, the following works and does what I want:

configurations {
  runtime.exclude group: "org.slf4j", module: "slf4j-log4j12"
}

It seems that an Exclude Rule only has two attributes - group and module. However, the above syntax doesn't prevent you from specifying any arbitrary property as a predicate. When trying to exclude from an individual dependency you cannot specify arbitrary properties. For example, this fails:

dependencies {
  compile ('org.springframework.data:spring-data-hadoop-core:2.0.0.M4-hadoop22') {
    exclude group: "org.slf4j", name: "slf4j-log4j12"
  }
}

with

No such property: name for class: org.gradle.api.internal.artifacts.DefaultExcludeRule

So even though you can specify a dependency with a group: and name: you can't specify an exclusion with a name:!?!

Perhaps a separate question, but what exactly is a module then? I can understand the Maven notion of groupId:artifactId:version, which I understand translates to group:name:version in Gradle. But then, how do I know what module (in gradle-speak) a particular Maven artifact belongs to?

You can use this solution. (Use nuget package) The source code is available on : Github: https://github.com/michelcedric/UserImpersonation

More detail https://michelcedric.wordpress.com/2015/09/03/usurpation-didentite-dun-user-c-user-impersonation/

I learned that depth and height are properties of a node:

• The depth of a node is the number of edges from the node to the tree's root node.
  A root node will have a depth of 0.

• The height of a node is the number of edges on the longest path from the node to a leaf.
  A leaf node will have a height of 0.

Properties of a tree:

• The height of a tree would be the height of its root node,
  or equivalently, the depth of its deepest node.

• The diameter (or width) of a tree is the number of nodes on the longest path between any two leaf nodes. The tree below has a diameter of 6 nodes.

Refer django docs on static files.

In settings.py:

import os
CURRENT_PATH = os.path.abspath(os.path.dirname(__file__).decode('utf-8'))

MEDIA_ROOT = os.path.join(CURRENT_PATH, 'media')

MEDIA_URL = '/media/'

STATIC_ROOT = 'static/'

STATIC_URL = '/static/'

STATICFILES_DIRS = (
                    os.path.join(CURRENT_PATH, 'static'),
)

Then place your js and css files static folder in your project. Not in media folder.

In views.py:

from django.shortcuts import render_to_response, RequestContext

def view_name(request):
    #your stuff goes here
    return render_to_response('template.html', locals(), context_instance = RequestContext(request))

In template.html:

<link rel="stylesheet" type="text/css" href="{{ STATIC_URL }}css/style.css" />
<script type="text/javascript" src="{{ STATIC_URL }}js/jquery-1.8.3.min.js"></script>

In urls.py:

from django.conf import settings
urlpatterns += patterns('',
    url(r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT, 'show_indexes': True}),
)

Project file structure can be found here in imgbin.

Edit: I totally misunderstood the question. In the browser, I would use setTimeout. If it was important that it ran in another thread, I would use Web Workers.

add this to your css:

.carousel-inner > .item > img, .carousel-inner > .item > a > img {
    width: 100%;
}

There is no: nono and no: yesyes. The truth is in the middle And no reasons to be scared because of the next version of Angular.

From a logical point of view, if You have a Component and You want to inform other components that something happens, an event should be fired and this can be done in whatever way You (developer) think it should be done. I don't see the reason why to not use it and i don't see the reason why to use it at all costs. Also the EventEmitter name suggests to me an event happening. I usually use it for important events happening in the Component. I create the Service but create the Service file inside the Component Folder. So my Service file becomes a sort of Event Manager or an Event Interface, so I can figure out at glance to which event I can subscribe on the current component.

I know..Maybe I'm a bit an old fashioned developer. But this is not a part of Event Driven development pattern, this is part of the software architecture decisions of Your particular project.

Some other guys may think that use Observables directly is cool. In that case go ahead with Observables directly. You're not a serial killer doing this. Unless you're a psychopath developer, So far the Program works, do it.

Try using getTime (mdn doc) :

var diff = Math.abs(date1.getTime() - date2.getTime()) / 3600000;
if (diff < 18) { /* do something */ }

Using Math.abs() we don't know which date is the smallest. This code is probably more relevant :

var diff = (date1 - date2) / 3600000;
if (diff < 18) { array.push(date1); }

As pointed by @RSK IE8 doesn't support background-size. To figure out a way to deal with this, I used some IE specific hacks as showed here:

//IE8.0 Hack!
@media \0screen {
    .brand {
        background-image: url("./images/logo1.png");
        margin-top: 8px;
    }

    .navbar .brand {
        margin-left: -2px;
        padding-bottom: 2px;
    }
}

//IE7.0 Hack!
*+html .brand {
    background-image: url("./images/logo1.png");
    margin-top: 8px;
}

*+html .navbar .brand {
    margin-left: -2px;
    padding-bottom: 2px;
}

Using this I was able to change my logo image to a ugly resided picture. But the final result is fine. I suggest u try something like this.

I think that you'll find interesting stuff in the following answer of mine that I did for a previous similar question:

https://stackoverflow.com/q/5929469/551449

In this answer, I proposed a pattern that allows a regex to catch any kind of number and since I have nothing else to add to it, I think it is fairly complete

The following should prefix 'www' to any request that doesn't have one, and redirect the edited request to the new URI.

When I make a new project using React, to install the React modules I have to run "npm install" (PowerShell) from within the new projects ClientApp folder (e.g. "C:\Users\Chris\source\repos\HelloWorld2\HelloWorld2\ClientApp"). The .NET core WebApp with React needs to have the React files installed in the correct location for React commands to work properly.

As @Agam said,

You need this statement in your driver file: from AthleteList import AtheleteList

TO get pretty timing differences, then

// d1, d2 are dates
long diff = d2.getTime() - d1.getTime();

long diffSeconds = diff / 1000 % 60;
long diffMinutes = diff / (60 * 1000) % 60;
long diffHours = diff / (60 * 60 * 1000) % 24;
long diffDays = diff / (24 * 60 * 60 * 1000);

System.out.print(diffDays + " days, ");
System.out.print(diffHours + " hours, ");
System.out.print(diffMinutes + " minutes, ");
System.out.print(diffSeconds + " seconds.");

To remove leading and trailing whitespaces:

let trimmedString = string.stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceCharacterSet())

Swift 3 / Swift 4:

let trimmedString = string.trimmingCharacters(in: .whitespaces)

escape()

Don't use it! escape() is defined in section B.2.1.2 escape and the introduction text of Annex B says:

... All of the language features and behaviours specified in this annex have one or more undesirable characteristics and in the absence of legacy usage would be removed from this specification. ...
... Programmers should not use or assume the existence of these features and behaviours when writing new ECMAScript code....

Behaviour:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/escape

Special characters are encoded with the exception of: @*_+-./

The hexadecimal form for characters, whose code unit value is 0xFF or less, is a two-digit escape sequence: %xx.

For characters with a greater code unit, the four-digit format %uxxxx is used. This is not allowed within a query string (as defined in RFC3986):

query       = *( pchar / "/" / "?" )
pchar         = unreserved / pct-encoded / sub-delims / ":" / "@"
unreserved    = ALPHA / DIGIT / "-" / "." / "_" / "~"
pct-encoded   = "%" HEXDIG HEXDIG
sub-delims    = "!" / "$" / "&" / "'" / "(" / ")"
              / "*" / "+" / "," / ";" / "="

A percent sign is only allowed if it is directly followed by two hexdigits, percent followed by u is not allowed.

encodeURI()

Use encodeURI when you want a working URL. Make this call:

encodeURI("http://www.example.org/a file with spaces.html")

to get:

http://www.example.org/a%20file%20with%20spaces.html

Don't call encodeURIComponent since it would destroy the URL and return

http%3A%2F%2Fwww.example.org%2Fa%20file%20with%20spaces.html

Note that encodeURI, like encodeURIComponent, does not escape the ' character.

encodeURIComponent()

Use encodeURIComponent when you want to encode the value of a URL parameter.

var p1 = encodeURIComponent("http://example.org/?a=12&b=55")

Then you may create the URL you need:

var url = "http://example.net/?param1=" + p1 + "&param2=99";

And you will get this complete URL:

http://example.net/?param1=http%3A%2F%2Fexample.org%2F%Ffa%3D12%26b%3D55&param2=99

Note that encodeURIComponent does not escape the ' character. A common bug is to use it to create html attributes such as href='MyUrl', which could suffer an injection bug. If you are constructing html from strings, either use " instead of ' for attribute quotes, or add an extra layer of encoding (' can be encoded as %27).

For more information on this type of encoding you can check: http://en.wikipedia.org/wiki/Percent-encoding

Check $ git log, copy the SHA-1 ID of the two different commits, and run the git diff command with those IDs. for example:

$ git diff (sha-id-one) (sha-id-two)

Well, here is a solution if you want the background to be other than a solid black color. We only need to invert the mask and apply it in a background image of the same size and then combine both background and foreground. A pro of this solution is that the background could be anything (even other image).

This example is modified from Hough Circle Transform. First image is the OpenCV logo, second the original mask, third the background + foreground combined.

# http://opencv-python-tutroals.readthedocs.io/en/latest/py_tutorials/py_imgproc/py_houghcircles/py_houghcircles.html
import cv2
import numpy as np

# load the image
img = cv2.imread('E:\\FOTOS\\opencv\\opencv_logo.png')
img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)

# detect circles
gray = cv2.medianBlur(cv2.cvtColor(img, cv2.COLOR_RGB2GRAY), 5)
circles = cv2.HoughCircles(gray, cv2.HOUGH_GRADIENT, 1, 20, param1=50, param2=50, minRadius=0, maxRadius=0)
circles = np.uint16(np.around(circles))

# draw mask
mask = np.full((img.shape[0], img.shape[1]), 0, dtype=np.uint8)  # mask is only 
for i in circles[0, :]:
    cv2.circle(mask, (i[0], i[1]), i[2], (255, 255, 255), -1)

# get first masked value (foreground)
fg = cv2.bitwise_or(img, img, mask=mask)

# get second masked value (background) mask must be inverted
mask = cv2.bitwise_not(mask)
background = np.full(img.shape, 255, dtype=np.uint8)
bk = cv2.bitwise_or(background, background, mask=mask)

# combine foreground+background
final = cv2.bitwise_or(fg, bk)

Note: It is better to use the opencv methods because they are optimized.

This worked for me fine:

File 1:

    <html>
    <head></head>
    <body>
        <a href="#" onclick="window.open('file:///D:/Examples/file2.html'); return false">CLICK ME</a>
    </body>
    <footer></footer>
    </html>

File 2:

    <html>
        ...
    </html>

This method works regardless of whether or not the 2 files are in the same directory, BUT both files must be local.

For obvious security reasons, if File 1 is located on a remote server you absolutely cannot open a file on some client's host computer and trying to do so will open a blank target.

You can explicitly have a join like this:

$qb->innerJoin('c.phones', 'p', Join::ON, 'c.id = p.customerId');

But you need to use the namespace of the class Join from doctrine:

use Doctrine\ORM\Query\Expr\Join;

Or if you prefere like that:

$qb->innerJoin('c.phones', 'p', Doctrine\ORM\Query\Expr\Join::ON, 'c.id = p.customerId');

Otherwise, Join class won't be detected and your script will crash...

Here the constructor of the innerJoin method:

public function innerJoin($join, $alias, $conditionType = null, $condition = null);

You can find other possibilities (not just join "ON", but also "WITH", etc...) here: http://docs.doctrine-project.org/en/2.0.x/reference/query-builder.html#the-expr-class

EDIT

Think it should be:

$qb->select('c')
    ->innerJoin('c.phones', 'p', Join::ON, 'c.id = p.customerId')
    ->where('c.username = :username')
    ->andWhere('p.phone = :phone');

    $qb->setParameters(array(
        'username' => $username,
        'phone' => $phone->getPhone(),
    ));

Otherwise I think you are performing a mix of ON and WITH, perhaps the problem.

As has been mentioned, as of PHP 5.6+ you can (should!) use the ... token (aka "splat operator", part of the variadic functions functionality) to easily call a function with an array of arguments:

<?php
function variadic($arg1, $arg2)
{
    // Do stuff
    echo $arg1.' '.$arg2;
}

$array = ['Hello', 'World'];

// 'Splat' the $array in the function call
variadic(...$array);

// 'Hello World'

Note: array items are mapped to arguments by their position in the array, not their keys.

As per CarlosCarucce's comment, this form of argument unpacking is the fastest method by far in all cases. In some comparisons, it's over 5x faster than call_user_func_array.

Aside

Because I think this is really useful (though not directly related to the question): you can type-hint the splat operator parameter in your function definition to make sure all of the passed values match a specific type.

(Just remember that doing this it MUST be the last parameter you define and that it bundles all parameters passed to the function into the array.)

This is great for making sure an array contains items of a specific type:

<?php

// Define the function...

function variadic($var, SomeClass ...$items)
{
    // $items will be an array of objects of type `SomeClass`
}

// Then you can call...

variadic('Hello', new SomeClass, new SomeClass);

// or even splat both ways

$items = [
    new SomeClass,
    new SomeClass,
];

variadic('Hello', ...$items);

A somewhat common use case for creating an empty file is to trigger something else happening in a different process in the absence of more sophisticated in process communication. In this case, it can help to have the file creation be atomic from the outside world's point of view (particularly if the thing being triggered is going to delete the file to "consume" the trigger).

So it can help to create a junk name (Guid.NewGuid.ToString()) in the same directory as the file you want to create, and then do a File.Move from the temporary name to your desired name. Otherwise triggered code which checks for file existence and then deletes the trigger may run into race conditions where the file is deleted before it is fully closed out.

Having the temp file in the same directory (and file system) gives you the atomicity you may want. This gives something like.

public void CreateEmptyFile(string path)
{
    string tempFilePath = Path.Combine(Path.GetDirectoryName(path),
        Guid.NewGuid.ToString());
    using (File.Create(tempFilePath)) {}
    File.Move(tempFilePath, path);
}

So ah, this is the real answer now.

import Combine

    }
}

I had a similar problem on Internet Explorer, and got the same error number. The culprit was an HTML comment. I know it sounds unbelievable, so here is the story.

I saw a series of 6 articles on the Internet. I liked them, so I decided to download the 6 Web-Pages and store them on my Hard Drive. At the top of each page, was a couple of HTML <a> Tags, that would allow you to go to the next article or the previous article. So I changed the href attribute to point to the next folder on my Hard Drive, instead of the next URL on the Internet.

After all of the links had been re-directed, the Browser refused to display any of the Web-Pages when I clicked on the Links. The message in the Console was the Error Number that was mentioned at the top of this page.

However, the real problem was a Comment. Whenever you download a Web-Page using Google Chrome, the Chrome Browser inserts a Comment at the very top of the page that includes the URL of the location that you got the Web-Page from. After I removed the Comment at the top of each one of the 6 Pages, all of the Links worked fine ( although I continued to get the same Error Message in the Console. )

Your command should include the url parameter as stated in the script usage comments. The main function has 2 parameters, url and out (which is set to a default value) C:\python23\python "C:\PathToYourScript\SCRIPT.py" http://yoururl.com "C:\OptionalOutput\"

You might need to build an inverted index for your database. It is assured to be pretty fast.

Imports :

org.apache.commons.io.comparator.LastModifiedFileComparator

Apache Commons

Code :

public static void main(String[] args) throws IOException {
        File directory = new File(".");
        // get just files, not directories
        File[] files = directory.listFiles((FileFilter) FileFileFilter.FILE);

        System.out.println("Default order");
        displayFiles(files);

        Arrays.sort(files, LastModifiedFileComparator.LASTMODIFIED_COMPARATOR);
        System.out.println("\nLast Modified Ascending Order (LASTMODIFIED_COMPARATOR)");
        displayFiles(files);

        Arrays.sort(files, LastModifiedFileComparator.LASTMODIFIED_REVERSE);
        System.out.println("\nLast Modified Descending Order (LASTMODIFIED_REVERSE)");
        displayFiles(files);

    }

You can use the * selector to change the child styles back to the default

example

#parent {
    white-space: pre-wrap;
}

#parent * {
    white-space: initial;
}

I have a far more simple solution, it is working for me; it is also a workaround but might be usable and you dont have to change your settings. I assume you can use value that will never be there, then you use it on your WHERE clause

DELETE FROM MyTable WHERE MyField IS_NOT_EQUAL AnyValueNoItemOnMyFieldWillEverHave

I don't like that solution either too much, that's why I am here, but it works and it seems better than what it has been answered

I had the same issue. He is what I found:

1) make sure all projects are using the same Framework (this is crucial!)

2) in Tools/Options>Debugging>General make sure "Enable Just My Code (Managed Only) is NOT ticked

3) in Tools/Options>Debugging>Symbols clear any cached symbols, untick and delete all folder locations under the "Symbols file (.pdb) locations" listbox except the default "Microsoft Symbol Servers" but still untick it too. Also delete any static paths in the "Cache symbols in this directory" textbox. Click the "Empty Symbols Cache" button. Finally make sure the "Only specified modules" radio button is ticked.

4) in the Build/Configuration Manager menu for all projects make sure the configuration is in Debug mode.

How to reproduce this error in PHP:

Create an empty array and ask for the value given a key like this:

php> $foobar = array();

php> echo gettype($foobar);
array

php> echo $foobar[0];

PHP Notice:  Undefined offset: 0 in 
/usr/local/lib/python2.7/dist-packages/phpsh/phpsh.php(578) : 
eval()'d code on line 1

What happened?

You asked an array to give you the value given a key that it does not contain. It will give you the value NULL then put the above error in the errorlog.

It looked for your key in the array, and found undefined.

How to make the error not happen?

Ask if the key exists first before you go asking for its value.

php> echo array_key_exists(0, $foobar) == false;
1

If the key exists, then get the value, if it doesn't exist, no need to query for its value.

You've got two common situations. The first is that you want random numbers and aren't too fussed about the quality or execution speed. In that case, use the following macro

#define uniform() (rand()/(RAND_MAX + 1.0))

that gives you p in the range 0 to 1 - epsilon (unless RAND_MAX is bigger than the precision of a double, but worry about that when you come to it).

int x = (int) (uniform() * N);

Now gives a random integer on 0 to N -1.

If you need other distributions, you have to transform p. Or sometimes it's easier to call uniform() several times.

If you want repeatable behaviour, seed with a constant, otherwise seed with a call to time().

Now if you are bothered about quality or run time performance, rewrite uniform(). But otherwise don't touch the code. Always keep uniform() on 0 to 1 minus epsilon. Now you can wrap the C++ random number library to create a better uniform(), but that's a sort of medium-level option. If you are bothered about the characteristics of the RNG, then it's also worth investing a bit of time to understand how the underlying methods work, then provide one. So you've got complete control of the code, and you can guarantee that with the same seed, the sequence will always be exactly the same, regardless of platform or which version of C++ you are linking to.

you can use one of the following:

(falseVal, trueVal)[TEST]

TEST and trueVal or falseVal

You're missing a reference to System.Linq.

Add

using System.Linq

to get access to the ToList() function on the current code file.

To give a little bit of information over why this is necessary, Enumerable.ToList<TSource> is an extension method. Extension methods are defined outside the original class that it targets. In this case, the extension method is defined on System.Linq namespace.

For a dynamic approach, if your labels are always in front of your text areas:

$(object).prev("label").text(charsleft);

Use compiler's flag, e.g. flag for GCC: -Wno-unused-variable

RTSP (actually RTP) can be used for streaming video, but also many other types of media including live presentations. Rtsp is just the protocol used to setup the RTP session.

For all the details you can check out my open source RTSP Server implementation on the following address: https://net7mma.codeplex.com/

Or my article @ http://www.codeproject.com/Articles/507218/Managed-Media-Aggregation-using-Rtsp-and-Rtp

It supports re-sourcing streams as well as the dynamic creation of streams, various RFC's are implemented and the library achieves better performance and less memory then FFMPEG and just about any other solutions in the transport layer and thus makes it a good candidate to use as a centralized point of access for most scenarios.

So let's say after getMasterData servlet will response.sendRedirect to to test.jsp.

In test.jsp

Create a javascript

<script type="text/javascript">
function alertName(){
alert("Form has been submitted");
} 
</script> 

and than at the bottom

<script type="text/javascript"> window.onload = alertName; </script>

Note:im not sure how to type the code in stackoverflow!. Edit: I just learned how to

Edit 2: TO the question:This works perfectly. Another question. How would I get rid of the initial alert when I first start up the JSP? "Form has been submitted" is present the second I execute. It shows up after the load is done to which is perfect.

To do that i would highly recommendation to use session!

So what you want to do is in your servlet:

session.setAttribute("getAlert", "Yes");//Just initialize a random variable.
response.sendRedirect(test.jsp);

than in the test.jsp

<%
session.setMaxInactiveInterval(2);
%>

 <script type="text/javascript">
var Msg ='<%=session.getAttribute("getAlert")%>';
    if (Msg != "null") {
 function alertName(){
 alert("Form has been submitted");
 } 
 }
 </script> 

and than at the bottom

<script type="text/javascript"> window.onload = alertName; </script>

So everytime you submit that form a session will be pass on! If session is not null the function will run!

For any CSS3-enabled browser you can use an adjacent sibling selector for styling your labels

input:checked + label {
    color: white;
}  

MDN's browser compatibility table says essentially all of the current, popular browsers (Chrome, IE, Firefox, Safari), on both desktop and mobile, are compatible.

Here are the steps solved for me:

1. Remove Class name reference from View(storyboard/xib) and save;
2. Add Class name again and save;
3. Clean and Build;

Done !

As of git v1.7.2 cherry pick can accept a range of commits:

git cherry-pick learned to pick a range of commits (e.g. cherry-pick A..B and cherry-pick --stdin), so did git revert; these do not support the nicer sequencing control rebase [-i] has, though.

So my solution was to also set localStorage when setting my state and then get the value from localStorage again inside of the getInitialState callback like so:

getInitialState: function() {
    var selectedOption = localStorage.getItem( 'SelectedOption' ) || 1;

    return {
        selectedOption: selectedOption
    };
},

setSelectedOption: function( option ) {
    localStorage.setItem( 'SelectedOption', option );
    this.setState( { selectedOption: option } );
}

I'm not sure if this can be considered an Anti-Pattern but it works unless there is a better solution.

The following complete example will read an existing server.xml file from the current directory, append a new Server and re-write the file to server.xml. It does not work without an existing .xml file, so you will need to modify the code to handle that case.

import java.util.*;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;
import javax.xml.transform.dom.*;
import org.w3c.dom.*;
import javax.xml.parsers.*;

public class AddXmlNode {
    public static void main(String[] args) throws Exception {

        DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
        Document document = documentBuilder.parse("server.xml");
        Element root = document.getDocumentElement();

        Collection<Server> servers = new ArrayList<Server>();
        servers.add(new Server());

        for (Server server : servers) {
            // server elements
            Element newServer = document.createElement("server");

            Element name = document.createElement("name");
            name.appendChild(document.createTextNode(server.getName()));
            newServer.appendChild(name);

            Element port = document.createElement("port");
            port.appendChild(document.createTextNode(Integer.toString(server.getPort())));
            newServer.appendChild(port);

            root.appendChild(newServer);
        }

        DOMSource source = new DOMSource(document);

        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        Transformer transformer = transformerFactory.newTransformer();
        StreamResult result = new StreamResult("server.xml");
        transformer.transform(source, result);
    }

    public static class Server {
        public String getName() { return "foo"; }
        public Integer getPort() { return 12345; }
    }
}

Example server.xml file:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Servers>
  <server>
    <name>something</name>
    <port>port</port>
  </server>
</Servers>

The main change to your code is not creating a new "root" element. The above example just uses the current root node from the existing server.xml and then just appends a new Server element and re-writes the file.

Just using this will add "mynewclass" to the element with the id myElement and revert it on the next call.

<div id="showhide" class="meta-info" onclick="changeclass(this);">

function changeclass(element) {
    $(element).toggleClass('mynewclass');
}

Or for a slighly more jQuery way (you would run this after the DOM is loaded)

<div id="showhide" class="meta-info">

$('#showhide').click(function() {
    $(this).toggleClass('mynewclass');
});

See a working example of this here: http://jsfiddle.net/S76WN/

Ok, Denizens. So I have accepted the command line length limits as gospel for quite some time. So, what to do with one's assumptions? Naturally- check them.

I have a Fedora 22 machine at my disposal (meaning: Linux with bash4). I have created a directory with 500,000 inodes (files) in it each of 18 characters long. The command line length is 9,500,000 characters. Created thus:

seq 1 500000 | while read digit; do
    touch $(printf "abigfilename%06d\n" $digit);
done

And we note:

$ getconf ARG_MAX
2097152

Note however I can do this:

$ echo * > /dev/null

But this fails:

$ /bin/echo * > /dev/null
bash: /bin/echo: Argument list too long

I can run a for loop:

$ for f in *; do :; done

which is another shell builtin.

Careful reading of the documentation for ARG_MAX states, Maximum length of argument to the exec functions. This means: Without calling exec, there is no ARG_MAX limitation. So it would explain why shell builtins are not restricted by ARG_MAX.

And indeed, I can ls my directory if my argument list is 109948 files long, or about 2,089,000 characters (give or take). Once I add one more 18-character filename file, though, then I get an Argument list too long error. So ARG_MAX is working as advertised: the exec is failing with more than ARG_MAX characters on the argument list- including, it should be noted, the environment data.

Nowadays people are just using CSS3 transitions because it's a lot easier than messing with JS, browser support is reasonably good and it's merely cosmetic so it doesn't matter if it doesn't work.

Something like this gets the job done:

a {
  color:blue;
  /* First we need to help some browsers along for this to work.
     Just because a vendor prefix is there, doesn't mean it will
     work in a browser made by that vendor either, it's just for
     future-proofing purposes I guess. */
  -o-transition:.5s;
  -ms-transition:.5s;
  -moz-transition:.5s;
  -webkit-transition:.5s;
  /* ...and now for the proper property */
  transition:.5s;
}
a:hover { color:red; }

You can also transition specific CSS properties with different timings and easing functions by separating each declaration with a comma, like so:

a {
  color:blue; background:white;
  -o-transition:color .2s ease-out, background 1s ease-in;
  -ms-transition:color .2s ease-out, background 1s ease-in;
  -moz-transition:color .2s ease-out, background 1s ease-in;
  -webkit-transition:color .2s ease-out, background 1s ease-in;
  /* ...and now override with proper CSS property */
  transition:color .2s ease-out, background 1s ease-in;
}
a:hover { color:red; background:yellow; }

Demo here

we can access/pass arguments/variables from one class to another class using object reference.

#Class1
class Test:
    def __init__(self):
        self.a = 10
        self.b = 20
        self.add = 0

    def calc(self):
        self.add = self.a+self.b

#Class 2
class Test2:
    def display(self):
        print('adding of two numbers: ',self.add)
#creating object for Class1
obj = Test()
#invoking calc method()
obj.calc()
#passing class1 object to class2
Test2.display(obj)

You disable the strict mode using following code:

This is not recommended: use the AsyncTask interface.

Full code for both the methods

I use this.

public static byte[] toByteArray(InputStream is) throws IOException {
        ByteArrayOutputStream output = new ByteArrayOutputStream();
        try {
            byte[] b = new byte[4096];
            int n = 0;
            while ((n = is.read(b)) != -1) {
                output.write(b, 0, n);
            }
            return output.toByteArray();
        } finally {
            output.close();
        }
    }

I think, this is you exactly needed.

Here drawable(xml) file that creates rounded rectangle. round_rect_shape.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >

    <solid android:color="#ffffff" />

    <corners
        android:bottomLeftRadius="8dp"
        android:bottomRightRadius="8dp"
        android:topLeftRadius="8dp"
        android:topRightRadius="8dp" />

</shape>

Here layout file: my_layout.xml

<LinearLayout
    android:id="@+id/linearLayout1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/round_rect_shape"
    android:orientation="vertical"
    android:padding="5dp" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Something text"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:textColor="#ff0000" />

    <EditText

        android:layout_width="match_parent"
        android:layout_height="wrap_content" >

        <requestFocus />
    </EditText>
</LinearLayout>

-> In the above code, LinearLayout having the background(That is the key role to place to create rounded rectangle). So you can place any view like TextView, EditText... in that LinearLayout to see background as round rectangle for all.

When a script is loaded, any parameters that are passed are automatically loaded into a special variables $args. You can reference that in your script without first declaring it.

As an example, create a file called test.ps1 and simply have the variable $args on a line by itself. Invoking the script like this, generates the following output:

PowerShell.exe -File test.ps1 a b c "Easy as one, two, three"
a
b
c
Easy as one, two, three

As a general recommendation, when invoking a script by calling PowerShell directly I would suggest using the -File option rather than implicitly invoking it with the & - it can make the command line a bit cleaner, particularly if you need to deal with nested quotes.

When you need to accept a function as argument which takes no arguments and returns no result (void), in my opinion it is still best to have something like

  public interface Thunk { void apply(); }

somewhere in your code. In my functional programming courses the word 'thunk' was used to describe such functions. Why it isn't in java.util.function is beyond my comprehension.

In other cases I find that even when java.util.function does have something that matches the signature I want - it still doesn't always feel right when the naming of the interface doesn't match the use of the function in my code. I guess it's a similar point that is made elsewhere here regarding 'Runnable' - which is a term associated with the Thread class - so while it may have he signature I need, it is still likely to confuse the reader.

I recommend Vorlon, works like weinre. I like the UI of Vorlon, and it support SSL, my application is in HTTPS, I tried weinre with ngrok, ghostlab and vorlon, only vorlon works fine.

tl;dr

java.time.Instant                    // Represent a moment as seen in UTC. Internally, a count of nanoseconds since 1970-01-01T00:00Z.
.ofEpochSecond( 1_220_227_200L )     // Pass a count of whole seconds since the same epoch reference of 1970-01-01T00:00Z.

Know Your Data

People use various precisions in tracking time as a number since an epoch. So when you obtain some numbers to be interpreted as a count since an epoch, you must determine:

• What epoch?
  Many epochs dates have been used in various systems. Commonly used is POSIX/Unix time, where the epoch is the first moment of 1970 in UTC. But you should not assume this epoch.
• What precision?
  Are we talking seconds, milliseconds, microseconds, or nanoseconds since the epoch?
• What time zone?
  Usually a count since epoch is in UTC/GMT time zone, that is, has no time zone offset at all. But sometimes, when involving inexperienced or date-time ignorant programmers, there may be an implied time zone.

In your case, as others noted, you seem to have been given seconds since the Unix epoch. But you are passing those seconds to a constructor that expects milliseconds. So the solution is to multiply by 1,000.

Lessons learned:

• Determine, don't assume, the meaning of received data.
• Read the doc.

Your Data

Your data seems to be in whole seconds. If we assume an epoch of the beginning of 1970, and if we assume UTC time zone, then 1,220,227,200 is the first moment of the first day of September 2008.

Joda-Time

The java.util.Date and .Calendar classes bundled with Java are notoriously troublesome. Avoid them. Use instead either the Joda-Time library or the new java.time package bundled in Java 8 (and inspired by Joda-Time).

Note that unlike j.u.Date, a DateTime in Joda-Time truly knows its own assigned time zone. So in the example Joda-Time 2.4 code seen below, note that we first parse the milliseconds using the default assumption of UTC. Then, secondly, we assign a time zone of Paris to adjust. Same moment in the timeline of the Universe, but different wall-clock time. For demonstration, we adjust again, to UTC. Almost always better to explicitly specify your desired/expected time zone rather than rely on an implicit default (often the cause of trouble in date-time work).

We need milliseconds to construct a DateTime. So take your input of seconds, and multiply by a thousand. Note that the result must be a 64-bit long as we would overflow a 32-bit int.

long input = 1_220_227_200L;  // Note the "L" appended to long integer literals.
long milliseconds = ( input * 1_000L ); // Use a "long", not the usual "int". Note the appended "L".

Feed that count of milliseconds to constructor. That particular constructor assumes the count is from the Unix epoch of 1970. So adjust time zone as desired, after construction.

Use proper time zone names, a combination of continent and city/region. Never use 3 or 4 letter codes such as EST as they are neither standardized not unique.

DateTime dateTimeParis = new DateTime( milliseconds ).withZone( DateTimeZone.forID( "Europe/Paris" ) );

For demonstration, adjust the time zone again.

DateTime dateTimeUtc = dateTimeParis.withZone( DateTimeZone.UTC );
DateTime dateTimeMontréal = dateTimeParis.withZone( DateTimeZone.forID( "America/Montreal" ) );

Dump to console. Note how the date is different in Montréal, as the new day has begun in Europe but not yet in America.

System.out.println( "dateTimeParis: " + dateTimeParis );
System.out.println( "dateTimeUTC: " + dateTimeUtc );
System.out.println( "dateTimeMontréal: " + dateTimeMontréal );

When run.

dateTimeParis: 2008-09-01T02:00:00.000+02:00
dateTimeUTC: 2008-09-01T00:00:00.000Z
dateTimeMontréal: 2008-08-31T20:00:00.000-04:00

java.time

The makers of Joda-Time have asked us to migrate to its replacement, the java.time framework as soon as is convenient. While Joda-Time continues to be actively supported, all future development will be done on the java.time classes and their extensions in the ThreeTen-Extra project.

The java-time framework is defined by JSR 310 and built into Java 8 and later. The java.time classes have been back-ported to Java 6 & 7 on the ThreeTen-Backport project and to Android in the ThreeTenABP project.

An Instant is a moment on the timeline in UTC with a resolution of nanoseconds. Its epoch is the first moment of 1970 in UTC.

Instant instant = Instant.ofEpochSecond( 1_220_227_200L );

Apply an offset-from-UTC ZoneOffset to get an OffsetDateTime.

Better yet, if known, apply a time zone ZoneId to get a ZonedDateTime.

ZoneId zoneId = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = ZonedDateTime.ofInstant( instant , zoneId );

You can pass arbitrary parameters through the query string, but you can also set up custom routes to handle it in a RESTful way:

http://ws.audioscrobbler.com/2.0/?method=artist.getimages&artist=cher&
                                  api_key=b25b959554ed76058ac220b7b2e0a026

That could be:

routes.MapRoute(
    "ArtistsImages",
    "{ws}/artists/{artist}/{action}/{*apikey}",
    new { ws = "2.0", controller="artists" artist = "", action="", apikey="" }
    );

So if someone used the following route:

ws.audioscrobbler.com/2.0/artists/cher/images/b25b959554ed76058ac220b7b2e0a026/

It would take them to the same place your example querystring did.

The above is just an example, and doesn't apply the business rules and constraints you'd have to set up to make sure people didn't 'hack' the URL.

There are two ways of getting query params:

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

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

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

Notepad++ will only auto-insert subsequent indents if you manually indent the first line in a block; otherwise you can re-indent your code after the fact using TextFX > TextFX Edit > Reindent C++ code.

Don't run it though addslashes(); if you're in the context of the HTML page, the HTML parser can still see the </script> tag, even mid-string, and assume it's the end of the JavaScript:

<?php
    $value = 'XXX</script><script>alert(document.cookie);</script>';
?>

<script type="text/javascript">
    var foo = <?= json_encode($value) ?>; // Use this
    var foo = '<?= addslashes($value) ?>'; // Avoid, allows XSS!
</script>

kdo

// reload page hack methode

push(uri: string) {
    this.location.replaceState(uri) // force replace and no show change
    await this.router.navigate([uri, { "refresh": (new Date).getTime() }]);
    this.location.replaceState(uri) // replace
  }

Distinct and the aggregation framework are not inter-operable.

Instead you just want:

db.zips.aggregate([ 
    {$group:{_id:{city:'$city', state:'$state'}, numberOfzipcodes:{$sum:1}}}, 
    {$sort:{numberOfzipcodes:-1}},
    {$group:{_id:'$_id.state', city:{$first:'$_id.city'}, 
              numberOfzipcode:{$first:'$numberOfzipcodes'}}}
]);

pgBadger is another option - also listed here: https://github.com/dhamaniasad/awesome-postgres#utilities

Requires some additional setup in advance to capture the necessary data in the postgres logs though, see the official website.

Like that

var purchCount = (from purchase in myBlaContext.purchases select purchase).Count();

or even easier

var purchCount = myBlaContext.purchases.Count()

Just you need to use 

//for bold
android:textStyle="bold"

//for italic
android:textStyle="italic"

//for normal
android:textStyle="normal"

<TextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textStyle="bold"
    android:text="@string/userName"
    android:layout_gravity="left"
    android:textSize="16sp"
/>

Please note for Windows 8 users you need to add/remove windows components and remove the version of .net reboot then re-install in order to register it with IIS. I presume this happens if you get .net 4.5 from visual studio and install IIS afterwards.

3 things you have to do, if you are doing it locally:

in php.ini or php.cfg of your php installation

post_max_size=500M

upload_max_filesize=500M

memory_limit=900M

or set other values. Restart Apache.

OR

Use php big dump tool its best ever i have seen. its free and opensource

Just add the keychain, as referenced in Ubuntu Quick Tips https://help.ubuntu.com/community/QuickTips

What

Instead of constantly starting up ssh-agent and ssh-add, it is possible to use keychain to manage your ssh keys. To install keychain, you can just click here, or use Synaptic to do the job or apt-get from the command line.

Command line

Another way to install the file is to open the terminal (Application->Accessories->Terminal) and type:

sudo apt-get install keychain

Edit File

You then should add the following lines to your ${HOME}/.bashrc or /etc/bash.bashrc:

keychain id_rsa id_dsa
. ~/.keychain/`uname -n`-sh

You need to encode Unicode explicitly before writing to a file, otherwise Python does it for you with the default ASCII codec.

Pick an encoding and stick with it:

f.write(printinfo.encode('utf8') + '\n')

or use io.open() to create a file object that'll encode for you as you write to the file:

import io

f = io.open(filename, 'w', encoding='utf8')

You may want to read:

• The Python Unicode HOWTO

• Pragmatic Unicode by Ned Batchelder

• The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!) by Joel Spolsky

before continuing.

You can use mouse events to control like hover. For example, the following code is making visible when you hover that element.

var foo = document.getElementById("foo");
foo.addEventListener('mouseover',function(){
   foo.style.display="block";
})
foo.addEventListener('mouseleave',function(){
   foo.style.display="none";
})

import * as utils from './utils.js'; 

If you do the above, you will be able to use functions in utils.js as

utils.someFunction()

You don't. The C++ standard has no concept of directories. It is up to the implementation to turn a string into a file handle. The contents of that string and what it maps to is OS dependent. Keep in mind that C++ can be used to write that OS, so it gets used at a level where asking how to iterate through a directory is not yet defined (because you are writing the directory management code).

Look at your OS API documentation for how to do this. If you need to be portable, you will have to have a bunch of #ifdefs for various OSes.

I was trying to animate Constraints and was not really easy to found a good explanation.

What other answers are saying is totally true: you need to call [self.view layoutIfNeeded]; inside animateWithDuration: animations:. However, the other important point is to have pointers for every NSLayoutConstraint you want to animate.

I created an example in GitHub.

First you need to input the two numbers say num_rows and num_columns perhaps using argc and argv then do a for loop to print the dots.

int j=0;
int k=0;
for (k=0;k<num_columns;k++){
   for (j=0;j<num_rows;j++){
       printf(".");
   }
 printf("\n");
 }

you'd have to replace the dot with something else later.

select{
    filter: progid:DXImageTransform.Microsoft.dropshadow(OffX=-1, OffY=-1,color=#FF0000) progid:DXImageTransform.Microsoft.dropshadow(OffX=1, OffY=1,color=#FF0000);
}

Works for me.

When You are sending a single quote in a query

empid = " T'via"
empid =escape(empid)

When You get the value including a single quote

var xxx  = request.QueryString("empid")
xxx= unscape(xxx)

If you want to search/ insert the value which includes a single quote in a query xxx=Replace(empid,"'","''")

Use immediate children selector >:

$('#tblOne > tbody  > tr')

Description: Selects all direct child elements specified by "child" of elements specified by "parent".

On Windows in general, running command prompt with administrator works. But if you don't want to do that every time, specify Full control permissions of your user (or simply all users) on Anaconda3 directory. Be aware that specifying it for all users allows other users to install their own packages and modify the content.

append: Appends object at the end.

x = [1, 2, 3]
x.append([4, 5])
print (x)

gives you: [1, 2, 3, [4, 5]]

extend: Extends list by appending elements from the iterable.

x = [1, 2, 3]
x.extend([4, 5])
print (x)

gives you: [1, 2, 3, 4, 5]

If you're like me and you don't like the idea of deleting things that were part of the standard system installation (which others have suggested) then you might like the solution I ended up using:

1. Get Homebrew - it's a one-line shell script to install!
2. Edit your .profile, or whatever is appropriate, and put /usr/local/bin at the start of your PATH so that Homebrew binaries are found before system binaries
3. brew install python - this installs a newer version of python in /usr/local
4. pip install pandas

This worked for me in OS X 10.8.2, and I can't see any reason it shouldn't work in 10.6.8.

When a parameter has [FromBody], Web API uses the Content-Type header to select a formatter. In this example, the content type is "application/json" and the request body is a raw JSON string (not a JSON object).

At most one parameter is allowed to read from the message body. So this will not work:

// Caution: Will not work!    
public HttpResponseMessage Post([FromBody] int id, [FromBody] string name) { ... }

The reason for this rule is that the request body might be stored in a non-buffered stream that can only be read once.

setTimeout(func, 5000);

-- it will call the function named func() after the time specified. here, 5000 milli seconds , i.e) after 5 seconds

EDIT: This code was used to show notes on top of a HTML5 video. It changes the font-size on the fly when the video is resized (when the browser window is resized.) The notes was connected to the video (just like notes on YouTube), which is why the code uses instances instead of a DOM handle directly.

As per request I'll throw in some code that I used to achieve this. (Text boxes over an HTML5 video.) The code was written a long time ago, and I quite frankly think it's pretty messy. Since the question is already answered and an answer is already accepted a long time ago I don't bother rewriting this. But if anyone wants to simplify this a bit, you're more than welcome!

// Figure out the text size:
var text = val['text'];
var letters = text.length;
var findMultiplier = function(x) { // g(x)
    /* By analysing some functions with regression, the resulting function that
     gives the best font size with respect to the number of letters and the size
     of the note is:
     g(x) = 8.3 - 2.75x^0.15 [1 < x < 255]
     f(x) = g(letters) * (x / 1000)^0.5
     Font size = f(size)
     */
    return 8.3 - 2.75 * Math.pow(x, 0.15);
};

var findFontSize = function(x) { // f(x)
    return findMultiplier(letters) * Math.pow(x / 1000, 0.5);
};

val.setFontSizeListener = function() {
    p.style.fontSize = '1px'; // So the text should not overflow the box when measuring.
    var noteStyle = window.getComputedStyle(table);
    var width = noteStyle.getPropertyValue('width');
    var height = noteStyle.getPropertyValue('height');
    var size = width.substring(0, width.length - 2) * height.substring(0, height.length - 2);
    p.style.fontSize = findFontSize(size) + 'px';
};
window.addEventListener('resize', val.setFontSizeListener);

You'll probably need to tweak these numbers from font-family to font-family. A good way to do this is download a free graph visualizer called GeoGebra. Change the length of the text and the size of the box. Then you manually set the size. Plot the manual results into the coordinate system. Then you enter the two equations I've posted here and you tweak the numbers until "my" graph fits your own manually plotted points.

You could use a pre tag instead of a div. This would automatically display your \n's in the correct way.

<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
<script>
$(document).ready(function(){
         var display_txt = "1st line text" +"\n" + "2nd line text";
         $('#somediv').html(display_txt).css("color", "green");
});
</script>
</head>
<body>

<pre>
<p id="somediv"></p>
</pre>

</body>
</html>

\p{L} matches a single code point in the category "letter".
\p{N} matches any kind of numeric character in any script.

If you're going to work with regular expressions a lot, I'd suggest bookmarking that site, it's very useful.

This would become a bit more clear if you add a line to both examples:

var result = database.query("SELECT * FROM hugetable");
console.log(result.length);
console.log("Hello World");

The second one:

database.query("SELECT * FROM hugetable", function(rows) {
   var result = rows;
   console.log(result.length);
});
console.log("Hello World");

Try running these, and you’ll notice that the first (synchronous) example, the result.length will be printed out BEFORE the 'Hello World' line. In the second (the asynchronous) example, the result.length will (most likely) be printed AFTER the "Hello World" line.

That's because in the second example, the database.query is run asynchronously in the background, and the script continues straightaway with the "Hello World". The console.log(result.length) is only executed when the database query has completed.

In Linux Ubuntu(maybe also another - it's not tested) distribution with PHP 5 on board, you can use:

sudo php5dismod xdebug

And with PHP 7

sudo phpdismod xdebug

And after that, please restart the server:

sudo service apache2 restart

Mario Gleichman describes how to use Java 1.5 generic functions to simulate Scala List literals, though sadly you wind up with immutable Lists.

He defines this class:

package literal;

public class collection {
    public static <T> List<T> List(T...elems){
        return Arrays.asList( elems );
    }
}

and uses it thusly:

import static literal.collection.List;
import static system.io.*;

public class CollectionDemo {
    public void demoList(){
        List<String> slist = List( "a", "b", "c" );
        List<Integer> iList = List( 1, 2, 3 );
        for( String elem : List( "a", "java", "list" ) )
            System.out.println( elem );
    }
}

Google Collections, now part of Guava supports a similar idea for list construction. In this interview, Jared Levy says:

[...] the most heavily-used features, which appear in almost every Java class I write, are static methods that reduce the number of repetitive keystrokes in your Java code. It's so convenient being able to enter commands like the following:

Map<OneClassWithALongName, AnotherClassWithALongName> = Maps.newHashMap();

List<String> animals = Lists.immutableList("cat", "dog", "horse");

7/10/2014: If only it could be as simple as Python's:

animals = ['cat', 'dog', 'horse']

2/21/2020: In Java 11 you can now say:

animals = List.of(“cat”, “dog”, “horse”)

Because you wanted to install specific package "I need to install only 1 package for my SF2 distribution (DoctrineFixtures)."

php composer.phar require package/package-name:package-version would be enough

var myArray = [
  {name: 'deepak', place: 'bangalore'}, 
  {name: 'chirag', place: 'bangalore'}, 
  {name: 'alok', place: 'berhampur'}, 
  {name: 'chandan', place: 'mumbai'}
];
var toRemove = [
  {name: 'deepak', place: 'bangalore'},
  {name: 'alok', place: 'berhampur'}
];



myArray = myArray.filter(ar => !toRemove.find(rm => (rm.name === ar.name && ar.place === rm.place) ))

Kind of, use the XmlAttribute instead of XmlElement, but it won't look like what you want. It will look like the following:

<SomeModel SomeStringElementName="testData"> 
</SomeModel> 

The only way I can think of to achieve what you want (natively) would be to have properties pointing to objects named SomeStringElementName and SomeInfoElementName where the class contained a single getter named "value". You could take this one step further and use DataContractSerializer so that the wrapper classes can be private. XmlSerializer won't read private properties.

// TODO: make the class generic so that an int or string can be used.
[Serializable]  
public class SerializationClass
{
    public SerializationClass(string value)
    {
        this.Value = value;
    }

    [XmlAttribute("value")]
    public string Value { get; }
}


[Serializable]                     
public class SomeModel                     
{                     
    [XmlIgnore]                     
    public string SomeString { get; set; }                     

    [XmlIgnore]                      
    public int SomeInfo { get; set; }  

    [XmlElement]
    public SerializationClass SomeStringElementName
    {
        get { return new SerializationClass(this.SomeString); }
    }               
}

You should always include all relevant code when asking a question. In this case, the print statement that is the center of your question. The print statement is probably the most crucial piece of information. The second most crucial piece of information is the error, which you also did not include. Next time, include both of those.

print $ids should be a fairly hard statement to mess up, but it is possible. Possible reasons:

1. $ids is undefined. Gives the warning undefined value in print
2. $ids is out of scope. With use strict, gives fatal warning Global variable $ids needs explicit package name, and otherwise the undefined warning from above.
3. You forgot a semi-colon at the end of the line.
4. You tried to do print $ids $nIds, in which case perl thinks that $ids is supposed to be a filehandle, and you get an error such as print to unopened filehandle.

Explanations

1: Should not happen. It might happen if you do something like this (assuming you are not using strict):

my $var;
while (<>) {
    $Var .= $_;
}
print $var;

Gives the warning for undefined value, because $Var and $var are two different variables.

2: Might happen, if you do something like this:

if ($something) {
    my $var = "something happened!";
}
print $var;

my declares the variable inside the current block. Outside the block, it is out of scope.

3: Simple enough, common mistake, easily fixed. Easier to spot with use warnings.

4: Also a common mistake. There are a number of ways to correctly print two variables in the same print statement:

print "$var1 $var2";  # concatenation inside a double quoted string
print $var1 . $var2;  # concatenation
print $var1, $var2;   # supplying print with a list of args

Lastly, some perl magic tips for you:

use strict;
use warnings;

# open with explicit direction '<', check the return value
# to make sure open succeeded. Using a lexical filehandle.
open my $fh, '<', 'file.txt' or die $!;

# read the whole file into an array and
# chomp all the lines at once
chomp(my @file = <$fh>);
close $fh;

my $ids  = join(' ', @file);
my $nIds = scalar @file;
print "Number of lines: $nIds\n";
print "Text:\n$ids\n";

Reading the whole file into an array is suitable for small files only, otherwise it uses a lot of memory. Usually, line-by-line is preferred.

Variations:

• print "@file" is equivalent to $ids = join(' ',@file); print $ids;
• $#file will return the last index in @file. Since arrays usually start at 0, $#file + 1 is equivalent to scalar @file.

You can also do:

my $ids;
do {
    local $/;
    $ids = <$fh>;
}

By temporarily "turning off" $/, the input record separator, i.e. newline, you will make <$fh> return the entire file. What <$fh> really does is read until it finds $/, then return that string. Note that this will preserve the newlines in $ids.

Line-by-line solution:

open my $fh, '<', 'file.txt' or die $!; # btw, $! contains the most recent error
my $ids;
while (<$fh>) {
    chomp;
    $ids .= "$_ "; # concatenate with string
}
my $nIds = $.; # $. is Current line number for the last filehandle accessed.

Athough it is framework specific, Django 1.4 has this functionailty which works in a similar fashion to the link to the 'greenfelt' site in the above answer

Once I'd discovered all the information of how my client was handling the encryption/decryption at their end it was straight forward using the AesManaged example suggested by dtb.

The finally implemented code started like this:

    try
    {
        // Create a new instance of the AesManaged class.  This generates a new key and initialization vector (IV).
        AesManaged myAes = new AesManaged();

        // Override the cipher mode, key and IV
        myAes.Mode = CipherMode.ECB;
        myAes.IV = new byte[16] { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 }; // CRB mode uses an empty IV
        myAes.Key = CipherKey;  // Byte array representing the key
        myAes.Padding = PaddingMode.None;

        // Create a encryption object to perform the stream transform.
        ICryptoTransform encryptor = myAes.CreateEncryptor();

        // TODO: perform the encryption / decryption as required...

    }
    catch (Exception ex)
    {
        // TODO: Log the error 
        throw ex;
    }

As for your update, I was confused for the reasoning behind in. Dug a little deeper and found this gem:

• yoursite.com becomes yoursite.com/
• yoursite.com/ is a directory, so the welcome-file-list is scanned
• yoursite.com/CMS is the first welcome-file ("CMS" in the welcome-file-list), and there is a mapping of /CMS to the MyCMS servlet, so that servlet is accessed.

Source: http://wiki.metawerx.net/wiki/HowToUseAServletAsYourMainWebPage

So, the mapping then does make sense.

And one can now freely use ${pageContext.request.contextPath}/path/ as src/href for relative links!

Try this

Select 'ALTER TABLE ' + Table_Name  +'  drop constraint ' + Constraint_Name  from Information_Schema.CONSTRAINT_TABLE_USAGE

Select 'drop Procedure ' + specific_name  from Information_Schema.Routines where specific_name not like 'sp%' AND specific_name not like 'fn_%'

Select 'drop View ' + table_name  from Information_Schema.tables where Table_Type = 'VIEW'

SELECT 'DROP TRIGGER ' + name FROM sysobjects WHERE type = 'tr'

Select 'drop table ' + table_name  from Information_Schema.tables where Table_Type = 'BASE TABLE'

Firebase is a suite of features .

• Realtime Database
• Hosting
• Authentication
• Storage
• Cloud Messaging
• Remote Config
• Test Lab
• Crash Reporting
• Notifications
• App Indexing
• Dynamic Links
• Invites
• AdWords
• AdMob

I believe you are trying to compare Firebase Realtime Database with Mongo DB . Firebase Realtime Database stores data as JSON format and syncs to all updates of the data to all clients listening to the data . It abstracts you from all complexity that is needed to setup and scale any database . I will not recommend firebase where you have lot of complex scenarios where aggregation of data is needed .(Queries that need SUM/AVERAGE kind of stuff ) . Though this is recently achievable using Firebase functions . Modeling data in Firebase is tricky . But it is the best way to get you started instantaneously . MongoDB is a database. This give you lot of powerful features. But MongoDB when installed in any platform you need to manage it by yourself .

When i try to choose between Firebase or MongoDB(or any DB ) . I try to answer the following .

1. Are there many aggregation queries that gets executed .(Like in case of reporting tool or BI tool ) . If Yes dont go for Firebase
2. Do i need to perform lot of transaction . (If yes then i would not like to go with firebase) (Tranactions are somewhat easy though after introduction of functions but that is also a overhead if lot of transactions needs to be maintained)
3. What timeline do i have to get things up and running .(Firebase is very easy to setup and integrate ).
4. Do i have expertise to scale up the DB and trouble shoot DB related stuffs . (Firebase is more like SAAS so no need to worry about scaleability)

If you want to get the count of records then you have to apply the group by on some field or apply the below query.

Like

db.rawQuery("select count(field) as count_record from tablename where field =" + condition, null);

Using sed:

sed -n -e '/^abc$/,/^mno$/{ /^abc$/d; /^mno$/d; p; }'

The -n option means do not print by default.

The pattern looks for lines containing just abc to just mno, and then executes the actions in the { ... }. The first action deletes the abc line; the second the mno line; and the p prints the remaining lines. You can relax the regexes as required. Any lines outside the range of abc..mno are simply not printed.

For Rails 4

The generator accepts column type as references (also available as belongs_to).

This migration will create a user_id column and appropriate index:

$ rails g migration AddUserRefToProducts user:references 

generates:

class AddUserRefToProducts < ActiveRecord::Migration
  def change
    add_reference :products, :user, index: true
  end
end

http://guides.rubyonrails.org/active_record_migrations.html#creating-a-standalone-migration

For Rails 3

Helper is called references (also available as belongs_to).

This migration will create a category_id column of the appropriate type. Note that you pass the model name, not the column name. Active Record adds the _id for you.

change_table :products do |t|
  t.references :category
end

If you have polymorphic belongs_to associations then references will add both of the columns required:

change_table :products do |t|
  t.references :attachment, :polymorphic => {:default => 'Photo'}
end

Will add an attachment_id column and a string attachment_type column with a default value of Photo.

SELECT *, CONVERT( UNCOMPRESS(column) USING "utf8" ) AS column FROM table_name

This is a clear answer to your question: How do I force my .NET application to run as administrator?

Summary:

Right Click on project -> Add new item -> Application Manifest File

Then in that file change a line like this:

<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />

Compile and run!

I use this JS snippet code :

First of all, I reach all the classes then according to index of my target class, I set className = "".

Target = document.getElementsByClassName("yourClass")[1];
Target.className="";

List<string> l = new List<string> { "@bob.com", "@tom.com" };
List<string> l2 = new List<string> { "[email protected]", "[email protected]" };
List<string> myboblist= (l2.Where (i=>i.Contains("bob")).ToList<string>());
foreach (var bob in myboblist)
    Console.WriteLine(bob.ToString());

I had accidentally enabled a different mode for the tab key. Fixed it by pressing Ctrl+Shift(for Mac only)+M.

From the Visual Studio Code Keybinding docs:

| Key      | Command                                 | Command id                       |
| Ctrl + M | Toggle Use of Tab Key for Setting Focus | editor.action.toggleTabFocusMode |

The current tab control mode should also show up in the status bar:

If there is only ever one line then do something like this:

using System;
using System.IO;

class Program
{
    static void Main()
    {
        String[] values = File.ReadAllText(@"d:\test.csv").Split(',');
    }
}

If you want to sort by something like creation date you probably need to use DirectoryInfo.GetFiles and then sort the resulting array using a suitable Predicate.

this should work, haven't tried though. this will exclude zero. NULL is excluded by default

AVG (CASE WHEN SecurityW <> 0 THEN SecurityW ELSE NULL END)
