The static code block can be used to instantiate or initialize class variables (as opposed to object variables). So declaring "a" static means that is only one shared by all Test objects, and the static code block initializes "a" only once, when the Test class is first loaded, no matter how many Test objects are created.

If you really want something simple and know how to write/run Python, take a look at the script Bas Bosschert: sources

#!/usr/bin/env python

import sys
from Crypto.Cipher import AES

try:
    wafile=sys.argv[1]
except:
    print "Usage: %s <msgstore.db.crypt>" % __file__
    sys.exit(1)

key = "346a23652a46392b4d73257c67317e352e3372482177652c".decode('hex')
cipher = AES.new(key,1)
open('msgstore.db',"wb").write(cipher.decrypt(open(wafile,"rb").read()))

Sending email programmatically with Kotlin.

• simple email sending, not all the other features (like attachments).
• TLS is always on
• Only 1 gradle email dependency needed also.

I also found this list of email POP services really helpful:

https://support.office.com/en-gb/article/pop-and-imap-email-settings-for-outlook-8361e398-8af4-4e97-b147-6c6c4ac95353

How to use:

    val auth = EmailService.UserPassAuthenticator("yourUser", "yourPass")
    val to = listOf(InternetAddress("[email protected]"))
    val from = InternetAddress("[email protected]")
    val email = EmailService.Email(auth, to, from, "Test Subject", "Hello Body World")
    val emailService = EmailService("yourSmtpServer", 587)

    GlobalScope.launch { // or however you do background threads
        emailService.send(email)
    }

The code:

import java.util.*
import javax.mail.*
import javax.mail.internet.InternetAddress
import javax.mail.internet.MimeBodyPart
import javax.mail.internet.MimeMessage
import javax.mail.internet.MimeMultipart

class EmailService(private var server: String, private var port: Int) {

    data class Email(
        val auth: Authenticator,
        val toList: List<InternetAddress>,
        val from: Address,
        val subject: String,
        val body: String
    )

    class UserPassAuthenticator(private val username: String, private val password: String) : Authenticator() {
        override fun getPasswordAuthentication(): PasswordAuthentication {
            return PasswordAuthentication(username, password)
        }
    }

    fun send(email: Email) {
        val props = Properties()
        props["mail.smtp.auth"] = "true"
        props["mail.user"] = email.from
        props["mail.smtp.host"] = server
        props["mail.smtp.port"] = port
        props["mail.smtp.starttls.enable"] = "true"
        props["mail.smtp.ssl.trust"] = server
        props["mail.mime.charset"] = "UTF-8"
        val msg: Message = MimeMessage(Session.getDefaultInstance(props, email.auth))
        msg.setFrom(email.from)
        msg.sentDate = Calendar.getInstance().time
        msg.setRecipients(Message.RecipientType.TO, email.toList.toTypedArray())
//      msg.setRecipients(Message.RecipientType.CC, email.ccList.toTypedArray())
//      msg.setRecipients(Message.RecipientType.BCC, email.bccList.toTypedArray())
        msg.replyTo = arrayOf(email.from)

        msg.addHeader("X-Mailer", CLIENT_NAME)
        msg.addHeader("Precedence", "bulk")
        msg.subject = email.subject

        msg.setContent(MimeMultipart().apply {
            addBodyPart(MimeBodyPart().apply {
                setText(email.body, "iso-8859-1")
                //setContent(email.htmlBody, "text/html; charset=UTF-8")
            })
        })
        Transport.send(msg)
    }

    companion object {
        const val CLIENT_NAME = "Android StackOverflow programmatic email"
    }
}

Gradle:

dependencies {
    implementation 'com.sun.mail:android-mail:1.6.4'
    implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core:1.3.3"
}

AndroidManifest:

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

This works for me. Has a nice delayed action going on.

var $mouseX = 0, $mouseY = 0;
var $xp = 0, $yp =0;

$(document).mousemove(function(e){
    $mouseX = e.pageX;
    $mouseY = e.pageY;    
});

var $loop = setInterval(function(){
// change 12 to alter damping higher is slower
$xp += (($mouseX - $xp)/12);
$yp += (($mouseY - $yp)/12);
$("#moving_div").css({left:$xp +'px', top:$yp +'px'});  
}, 30);

Nice and simples

Is JavaScript object-oriented?

Answer : Yes

It has objects which can contain data and methods that act upon that data. Objects can contain other objects.

• It does not have classes, but it does have constructors which do what classes do, including acting as containers for class variables and methods.
• It does not have class-oriented inheritance, but it does have prototype-oriented inheritance.

The two main ways of building up object systems are by inheritance (is-a) and by aggregation (has-a). JavaScript does both, but its dynamic nature allows it to excel at aggregation.

Some argue that JavaScript is not truly object oriented because it does not provide information hiding. That is, objects cannot have private variables and private methods: All members are public.

But it turns out that JavaScript objects can have private variables and private methods. (Click here now to find out how.) Of course, few understand this because JavaScript is the world's most misunderstood programming language.

Some argue that JavaScript is not truly object oriented because it does not provide inheritance. But it turns out that JavaScript supports not only classical inheritance, but other code reuse patterns as well.

You can also use v-model for the rescue

<template>
    <select name="LeaveType" v-model="leaveType" @change="onChange()" class="form-control">
         <option value="1">Annual Leave/ Off-Day</option>
         <option value="2">On Demand Leave</option>
    </select>
</template>

<script>
export default {
    data() {
        return {
            leaveType: '',
        }
    },

    methods: {
        onChange() {
            console.log('The new value is: ', this.leaveType)
        }
    }
}
</script>

There is corner case with some utf-8 characters

Example:

>>> from django.template.defaultfilters import slugify
>>> slugify(u"test aescóln")
u'test-aescon' # there is no "l"

This can be solved with Unidecode

>>> from unidecode import unidecode
>>> from django.template.defaultfilters import slugify
>>> slugify(unidecode(u"test aescóln"))
u'test-aescoln'

I have to find distinct rows with the following details class : Scountry
columns: countryID, countryName,isactive
There is no primary key in this. I have succeeded with the followin queries

public DbSet<SCountry> country { get; set; }
    public List<SCountry> DoDistinct()
    {
        var query = (from m in country group m by new { m.CountryID, m.CountryName, m.isactive } into mygroup select mygroup.FirstOrDefault()).Distinct();
        var Countries = query.ToList().Select(m => new SCountry { CountryID = m.CountryID, CountryName = m.CountryName, isactive = m.isactive }).ToList();
        return Countries;
    }

This is my solution(There is a nested LinearLayout):

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

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <TextView
            android:id="@+id/item"
            android:layout_width="match_parent"
            android:layout_height="47dp"
            android:background="@drawable/box_arrow_top_bg"
            android:gravity="center"
            android:text="????"
            android:textColor="#666"
            android:textSize="16sp" />
    </LinearLayout>

</LinearLayout>

The second parameter of the callback function passed to each() will contain the actual DOM element and not a jQuery wrapper object. You can call the getAttribute() method of the element:

$('#category_sorting_form_save').click(function() {
    var elements = $("#category_sorting_elements > div");
    $.each(elements, function(key, value) {
        console.info(key, ": ", value);
        console.info("cat_id: ", value.getAttribute('cat_id'));
    });
});

Or wrap the element in a jQuery object yourself:

$('#category_sorting_form_save').click(function() {
    var elements = $("#category_sorting_elements > div");
    $.each(elements, function(key, value) {
        console.info(key, ": ", value);
        console.info("cat_id: ", $(value).attr('cat_id'));
    });
});

Or simply use $(this):

$('#category_sorting_form_save').click(function() {
    var elements = $("#category_sorting_elements > div");
    $.each(elements, function() {
        console.info("cat_id: ", $(this).attr('cat_id'));
    });
});

Use the os.EOL constant instead.

var os = require("os");

function processInput ( text ) 
{     
  fs.open('H://log.txt', 'a', 666, function( e, id ) {
   fs.write( id, text + os.EOL, null, 'utf8', function(){
    fs.close(id, function(){
     console.log('file is updated');
    });
   });
  });
 }

You can also use the index for the sheet:

xls = pd.ExcelFile('path_to_file.xls')
sheet1 = xls.parse(0)

will give the first worksheet. for the second worksheet:

sheet2 = xls.parse(1)

1 : if you are interested only in the static block of the class , the loading the class only would do , and would execute static blocks then all you need is:

Class.forName("Somthing");

2 : if you are interested in loading the class , execute its static blocks and also want to access its its non static part , then you need an instance and then you need:

Class.forName("Somthing").newInstance();

In my case, there was something wrong with the .NET Core Windows Hosting Bundle installation.

I had that installed and had restarted IIS using ("net stop was /y" and "net start w3svc") after installation, but I would get that 500.19 error with Error Code 0x8007000d and Config Source -1: 0:.

I managed to resolve the issue by repairing the .NET Core Windows Hosting Bundle installation and restarting IIS using the commands I mentioned above.

Hope this helps someone!

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

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

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

And then:

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

It looks like your Spring component scan Base is missing UserServiceImpl

If you don't want to use a module you have to install like requests, and your use case is very basic, then you can use urllib2

urllib2.urlopen(url, body)

See the documentation for urllib2 here: https://docs.python.org/2/library/urllib2.html.

Try the below code

HttpRequest req = System.Web.HttpContext.Current.Request
string browserName = req.Browser.Browser;

Color.parseHexColor("17ee27") did not work for me, instead Color.parseColor("17ee27") worked perfectly.

When you use a function ...

<p onclick="update_url('/en/step2');">Link</p>

<script>
function update_url(url) {
    history.pushState(null, null, url);
}
</script>

Another possibility with Guava:

dependency: compile 'com.google.guava:guava:11.0.2'

import com.google.common.io.ByteStreams;
...

String total = new String(ByteStreams.toByteArray(inputStream ));

Iterable is a generic interface. A problem you might be having (you haven't actually said what problem you're having, if any) is that if you use a generic interface/class without specifying the type argument(s) you can erase the types of unrelated generic types within the class. An example of this is in Non-generic reference to generic class results in non-generic return types.

So I would at least change it to:

public class ProfileCollection implements Iterable<Profile> { 
    private ArrayList<Profile> m_Profiles;

    public Iterator<Profile> iterator() {        
        Iterator<Profile> iprof = m_Profiles.iterator();
        return iprof; 
    }

    ...

    public Profile GetActiveProfile() {
        return (Profile)m_Profiles.get(m_ActiveProfile);
    }
}

and this should work:

for (Profile profile : m_PC) {
    // do stuff
}

Without the type argument on Iterable, the iterator may be reduced to being type Object so only this will work:

for (Object profile : m_PC) {
    // do stuff
}

This is a pretty obscure corner case of Java generics.

If not, please provide some more info about what's going on.

Why use freopen()? The C89 specification has the answer in one of the endnotes for the section on <stdio.h>:

116. The primary use of the freopen function is to change the file associated with a standard text stream (stderr, stdin, or stdout), as those identifiers need not be modifiable lvalues to which the value returned by the fopen function may be assigned.

freopen is commonly misused, e.g. stdin = freopen("newin", "r", stdin);. This is no more portable than fclose(stdin); stdin = fopen("newin", "r");. Both expressions attempt to assign to stdin, which is not guaranteed to be assignable.

The right way to use freopen is to omit the assignment: freopen("newin", "r", stdin);

Since Laravel 5.2 you can use File Responses
Basically you can call it like this:

return response()->file($pathToFile);

and it will display files as PDF and images inline in the browser.

I have had the same problem. There is an answer:

• 1.CTRL + ALT + SHIFT + S;
  2. Then go to "Modules";
  3. "Dependencies;
  4. Change "Module SDK".

Got it! Now u have Java 9!

Nothing wrong with that implementation. You might give the yield keyword a shot, see how you like it:

private IEnumerable<TankReading> ConvertToTankReadings(DataTable dataTable)
    {
        foreach (DataRow row in dataTable.Rows)
        {
            yield return new TankReading
                                  {
                                      TankReadingsID = Convert.ToInt32(row["TRReadingsID"]),
                                      TankID = Convert.ToInt32(row["TankID"]),
                                      ReadingDateTime = Convert.ToDateTime(row["ReadingDateTime"]),
                                      ReadingFeet = Convert.ToInt32(row["ReadingFeet"]),
                                      ReadingInches = Convert.ToInt32(row["ReadingInches"]),
                                      MaterialNumber = row["MaterialNumber"].ToString(),
                                      EnteredBy = row["EnteredBy"].ToString(),
                                      ReadingPounds = Convert.ToDecimal(row["ReadingPounds"]),
                                      MaterialID = Convert.ToInt32(row["MaterialID"]),
                                      Submitted = Convert.ToBoolean(row["Submitted"]),
                                  };
        }

    }

Also the AsEnumerable isn't necessary, as List<T> is already an IEnumerable<T>

In iOS 6, tintColor tinted the background of navigation bars, tab bars, toolbars, search bars, and scope bars. To tint a bar background in iOS 7, use the barTintColor property instead.

CAST both fields to datatype DATE and you can use a minus:

(CAST(MAX(joindate) AS date) - CAST(MIN(joindate) AS date)) as DateDifference

Test case:

SELECT  (CAST(MAX(joindate) AS date) - CAST(MIN(joindate) AS date)) as DateDifference
FROM 
    generate_series('2014-01-01'::timestamp, '2014-02-01'::timestamp, interval '1 hour') g(joindate);

Result: 31

Or create a function datediff():

CREATE OR REPLACE FUNCTION datediff(timestamp, timestamp) 
RETURNS int 
LANGUAGE sql 
AS
$$
    SELECT CAST($1 AS date) - CAST($2 AS date) as DateDifference
$$;

Just simply use this Style of DataGridRow:

<DataGrid.RowStyle>
        <Style TargetType="DataGridRow">
            <Setter Property="IsEnabled" Value="{Binding RelativeSource={RelativeSource Self},Path=IsNewItem,Mode=OneWay}" />
        </Style>
</DataGrid.RowStyle>

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

Instead of using Input class you can also use old() helper to make this even shorter.

<option {{ old('name') == $key ? "selected" : "" }} value="{{ $value }}">

Ernesto is right. According to the link he posted [1]:

Updated Client JVM heap configuration

In the Client JVM...

• The default maximum heap size is half of the physical memory up to a physical memory size of 192 megabytes and otherwise one fourth of the physical memory up to a physical memory size of 1 gigabyte.

  For example, if your machine has 128 megabytes of physical memory, then the maximum heap size is 64 megabytes, and greater than or equal to 1 gigabyte of physical memory results in a maximum heap size of 256 megabytes.

• The maximum heap size is not actually used by the JVM unless your program creates enough objects to require it. A much smaller amount, termed the initial heap size, is allocated during JVM initialization. ...

• ...
• Server JVM heap configuration ergonomics are now the same as the Client, except that the default maximum heap size for 32-bit JVMs is 1 gigabyte, corresponding to a physical memory size of 4 gigabytes, and for 64-bit JVMs is 32 gigabytes, corresponding to a physical memory size of 128 gigabytes.

You just need to create a deleter class:

struct BarDeleter {
  void operator()(Bar* b) { destroy(b); }
};

and provide it as the template argument of unique_ptr. You'll still have to initialize the unique_ptr in your constructors:

class Foo {
  public:
    Foo() : bar(create()), ... { ... }

  private:
    std::unique_ptr<Bar, BarDeleter> bar;
    ...
};

As far as I know, all the popular c++ libraries implement this correctly; since BarDeleter doesn't actually have any state, it does not need to occupy any space in the unique_ptr.

You can't get around this restriction directly, no. But there may be some reasonable things you can do in your particular case.

For example, you could just "new up" an instance of your class in the static method, then call the non-static method.

But you might get even better suggestions if you post your class(es) -- or a slimmed-down version of them.

I use the following method to grab embedded resources:

    protected static Stream GetResourceStream(string resourcePath)
    {
        Assembly assembly = Assembly.GetExecutingAssembly();
        List<string> resourceNames = new List<string>(assembly.GetManifestResourceNames());

        resourcePath = resourcePath.Replace(@"/", ".");
        resourcePath = resourceNames.FirstOrDefault(r => r.Contains(resourcePath));

        if (resourcePath == null)
            throw new FileNotFoundException("Resource not found");

        return assembly.GetManifestResourceStream(resourcePath);
    }

I then call this with the path in the project:

GetResourceStream(@"DirectoryPathInLibrary/Filename")

Our version of Oracle is running on Red Hat Enterprise Linux. We experimented with several different types of group permissions to no avail. The /defaultdir directory had a group that was a secondary group for the oracle user. When we updated the /defaultdir directory to have a group of "oinstall" (oracle's primary group), I was able to select from the external tables underneath that directory with no problem.

So, for others that come along and might have this issue, make the directory have oracle's primary group as the group and it might resolve it for you as it did us. We were able to set the permissions to 770 on the directory and files and selecting on the external tables works fine now.

IMHO, a very nice solution is to use c++11 emplace_back function:

revenue.emplace_back("string", map[i].second);

It just creates a new element in place.

Summary

There are various interpretation and strong opinions of the exact layer that define an ABI (application binary interface).

In my view an ABI is a subjective convention of what is considered a given/platform for a specific API. The ABI is the "rest" of conventions that "will not change" for a specific API or that will be addressed by the runtime environment: executors, tools, linkers, compilers, jvm, and OS.

Defining an Interface: ABI, API

If you want to use a library like joda-time you must declare a dependency on joda-time-<major>.<minor>.<patch>.jar. The library follows best practices and use Semantic Versioning. This defines the API compatibility at three levels:

1. Patch - You don't need to change at all your code. The library just fixes some bugs.
2. Minor - You don't need to change your code since the additions
3. Major - The interface (API) is changed and you might need to change your code.

In order for you to use a new major release of the same library a lot of other conventions are still to be respected:

• The binary language used for the libraries (in Java cases the JVM target version that defines the Java bytecode)
• Calling conventions
• JVM conventions
• Linking conventions
• Runtime conventions All these are defined and managed by the tools we use.

Examples

Java case study

For example, Java standardized all these conventions, not in a tool, but in a formal JVM specification. The specification allowed other vendors to provide a different set of tools that can output compatible libraries.

Java provides two other interesting case studies for ABI: Scala versions and Dalvik virtual machine.

Dalvik virtual machine broke the ABI

The Dalvik VM needs a different type of bytecode than the Java bytecode. The Dalvik libraries are obtained by converting the Java bytecode (with same API) for Dalvik. In this way you can get two versions of the same API: defined by the original joda-time-1.7.2.jar. We could call it joda-time-1.7.2.jar and joda-time-1.7.2-dalvik.jar. They use a different ABI one is for the stack-oriented standard Java vms: Oracle's one, IBM's one, open Java or any other; and the second ABI is the one around Dalvik.

Scala successive releases are incompatible

Scala doesn't have binary compatibility between minor Scala versions: 2.X . For this reason the same API "io.reactivex" %% "rxscala" % "0.26.5" has three versions (in the future more): for Scala 2.10, 2.11 and 2.12. What is changed? I don't know for now, but the binaries are not compatible. Probably the latest versions adds things that make the libraries unusable on the old virtual machines, probably things related to linking/naming/parameter conventions.

Java successive releases are incompatible

Java has problems with the major releases of the JVM too: 4,5,6,7,8,9. They offer only backward compatibility. Jvm9 knows how to run code compiled/targeted (javac's -target option) for all other versions, while JVM 4 doesn't know how to run code targeted for JVM 5. All these while you have one joda-library. This incompatibility flies bellow the radar thanks to different solutions:

1. Semantic versioning: when libraries target higher JVM they usually change the major version.
2. Use JVM 4 as the ABI, and you're safe.
3. Java 9 adds a specification on how you can include bytecode for specific targeted JVM in the same library.

Why did I start with the API definition?

API and ABI are just conventions on how you define compatibility. The lower layers are generic in respect of a plethora of high level semantics. That's why it's easy to make some conventions. The first kind of conventions are about memory alignment, byte encoding, calling conventions, big and little endian encodings, etc. On top of them you get the executable conventions like others described, linking conventions, intermediate byte code like the one used by Java or LLVM IR used by GCC. Third you get conventions on how to find libraries, how to load them (see Java classloaders). As you go higher and higher in concepts you have new conventions that you consider as a given. That's why they didn't made it to the semantic versioning. They are implicit or collapsed in the major version. We could amend semantic versioning with <major>-<minor>-<patch>-<platform/ABI>. This is what is actually happening already: platform is already a rpm, dll, jar (JVM bytecode), war(jvm+web server), apk, 2.11 (specific Scala version) and so on. When you say APK you already talk about a specific ABI part of your API.

API can be ported to different ABI

The top level of an abstraction (the sources written against the highest API can be recompiled/ported to any other lower level abstraction.

Let's say I have some sources for rxscala. If the Scala tools are changed I can recompile them to that. If the JVM changes I could have automatic conversions from the old machine to the new one without bothering with the high level concepts. While porting might be difficult will help any other client. If a new operating system is created using a totally different assembler code a translator can be created.

APIs ported across languages

There are APIs that are ported in multiple languages like reactive streams. In general they define mappings to specific languages/platforms. I would argue that the API is the master specification formally defined in human language or even a specific programming language. All the other "mappings" are ABI in a sense, else more API than the usual ABI. The same is happening with the REST interfaces.

You can use the ScriptManager.RegisterStartupScript(); to call any of your javascript event/Client Event from the server. For example, to display a message using javascript's alert();, you can do this:

protected void ddl_SelectedIndexChanged(object sender, EventArgs e)
{
Response.write("<script>alert('This is my message');</script>");
 //----or alternatively and to be more proper
 ScriptManager.RegisterStartupScript(this, this.GetType(), "callJSFunction", "alert('This is my message')", true);
}

To be exact for you, do this...

protected void ddl_SelectedIndexChanged(object sender, EventArgs e)
{
 ScriptManager.RegisterStartupScript(this, this.GetType(), "callJSFunction", "CalcTotalAmt();", true);
}

Suggest you have a look at the USPS Address Information APIs. You can validate a zip and obtain standard formatted addresses. https://www.usps.com/business/web-tools-apis/address-information.htm

You can use axe selectors for this.

There are two approaches:

1. Immediate Parent axe Selector (<)

#a:hover < #content + #b

This axe style rule will select #b, which is the immediate sibling of #content, which is the immediate parent of #a which has a :hover state.

div {
display: inline-block;
margin: 30px;
font-weight: bold;
}

#content {
width: 160px;
height: 160px;
background-color: rgb(255, 0, 0);
}

#a, #b {
width: 100px;
height: 100px;
line-height: 100px;
text-align: center;
}

#a {
color: rgb(255, 0, 0);
background-color: rgb(255, 255, 0);
cursor: pointer;
}

#b {
display: none;
color: rgb(255, 255, 255);
background-color: rgb(0, 0, 255);
}

#a:hover < #content + #b {
display: inline-block;
}

<div id="content">
<div id="a">Hover me</div>
</div>

<div id="b">Show me</div>

<script src="https://rouninmedia.github.io/axe/axe.js"></script>

2. Remote Element axe Selector (\)

#a:hover \ #b

This axe style rule will select #b, which is present in the same document as #a which has a :hover state.

div {
display: inline-block;
margin: 30px;
font-weight: bold;
}

#content {
width: 160px;
height: 160px;
background-color: rgb(255, 0, 0);
}

#a, #b {
width: 100px;
height: 100px;
line-height: 100px;
text-align: center;
}

#a {
color: rgb(255, 0, 0);
background-color: rgb(255, 255, 0);
cursor: pointer;
}

#b {
display: none;
color: rgb(255, 255, 255);
background-color: rgb(0, 0, 255);
}

#a:hover \ #b {
display: inline-block;
}

<div id="content">
<div id="a">Hover me</div>
</div>

<div id="b">Show me</div>

<script src="https://rouninmedia.github.io/axe/axe.js"></script>

You can use a .Net environment Visual studio, Take a look at the differences with the PC version.

A lighter editor would be Visual Code

Alternatives :

1. Installing the Mono Project runtime . It allows you to re-compile the code and run it on a Mac, but this requires various alterations to the codebase, as the fuller .Net Framework is not available. (Also, WPF applications aren't supported here either.)

2. Virtual machine (VMWare Fusion perhaps)

3. Update your codebase to .Net Core, (before choosing this option take a look at this migration process)

   • .Net Core 3.1 is an open-source, free and available on Window, MacOs and Linux

   • As of September 14, a release candidate ¹ of .Net Core 5.0 has been deployed on Window, MacOs and Linux.

[1] : Release candidate (RC) : releases providing early access to complete features. These releases are supported for production use when they have a go-live license

$('input[type=file]').change(function(e){
    $(this).parents('.parent-selector').find('.element-to-paste-filename').text(e.target.files[0].name);
});

This code will not show C:\fakepath\ before file name in Google Chrome in case of using .val().

Note that if your canvas is statically declared you should use the width and height attributes, not the style, eg. this will work:

<canvas id="c" height="100" width="100" style="border:1px"></canvas>
<script>
    document.getElementById('c').width = 200;
</script>

But this will not work:

<canvas id="c" style="width: 100px; height: 100px; border:1px"></canvas>
<script>
    document.getElementById('c').width = 200;
</script>

I built on sabithpocker's idea and made a more generalized version that lets you control more than one selectbox from a given trigger.

I assigned the selectboxes I wanted to be controlled the classname "switchable," and cloned them all like this:

$j(this).data('options',$j('select.switchable option').clone());

and used a specific naming convention for the switchable selects, which could also translate into classes. In my case, "category" and "issuer" were the select names, and "category_2" and "issuer_1" the class names.

Then I ran an $.each on the select.switchable groups, after making a copy of $(this) for use inside the function:

var that = this;
$j("select.switchable").each(function() { 
    var thisname = $j(this).attr('name');
    var theseoptions = $j(that).data('options').filter( '.' + thisname + '_' + id );
    $j(this).html(theseoptions);
});     

By using a classname on the ones you want to control, the function will safely ignore other selects elsewhere on the page (such as the last one in the example on Fiddle).

Here's a Fiddle with the complete code:

You can change the JDK or JRE location using the following steps:

1. open the terminal or cmd.
   
2. go to the [tomcat-home]\bin directory.
   ex: c:\tomcat8\bin
3. write the following command: Tomcat8W //ES//Tomcat8
4. will open dialog, select the java tab(top pane).
5. change the Java virtual Machine value.
6. click OK.

note: in Apache TomEE same steps, but step (3) the command must be: TomEE //ES

# file? will only return true for files
File.file?(filename)

and

# Will also return true for directories - watch out!
File.exist?(filename)

Here's another method if you can safely use CSS3's transform property:

.fixed-horizontal-center
{
    position: fixed;
    top: 100px; /* or whatever top you need */
    left: 50%;
    width: auto;
    -webkit-transform: translateX(-50%);
    -moz-transform: translateX(-50%);
    -ms-transform: translateX(-50%);
    -o-transform: translateX(-50%);
    transform: translateX(-50%);
}

...or if you want both horizontal AND vertical centering:

.fixed-center
{
    position: fixed;
    top: 50%;
    left: 50%;
    width: auto;
    height: auto;
    -webkit-transform: translate(-50%,-50%);
    -moz-transform: translate(-50%,-50%);
    -ms-transform: translate(-50%,-50%);
    -o-transform: translate(-50%,-50%);
    transform: translate(-50%,-50%);
}

@Ciwan. You're right. The table goes to full width (much too wide). Not a good solution. Better to do this:

css:

.scrollme {
    overflow-x: auto;
}

html:

<div class="scrollme">                        
  <table class="table table-responsive"> ...
  </table>
</div>

Edit: changing scroll-y to scroll-x

For some git-commands you can specify --verbose,

git 'command' --verbose

or

git 'command' -v.

Make sure the switch is after the actual git command. Otherwise - it won't work!

Also useful:

git 'command' --dry-run 

The const keyword used with the function declaration specifies that it is a const member function and it will not be able to change the data members of the object.

Are you running on Localhost? and have you edit the php.ini ?

If not yet, try this:
1. Open xampp->php->php.ini
2. Search for extension=php_openssl.dll
3. The initial will look like this ;extension=php_openssl.dll
4. Remove the ';' and it will look like this extension=php_openssl.dll
5. If you can't find the extension=php_openssl.dll, add this line extension=php_openssl.dll.
6. Then restart your Xampp.

Goodluck ;)

You can do it using simple jQuery loop.

Use tuple unpacking:

>>> pairs = [("a", 1), ("b", 2), ("c", 3)]
>>> for a, b in pairs:
...    print a, b
... 
a 1
b 2
c 3

See also: Tuple unpacking in for loops.

With the dplyr package, you can use summarise_all, summarise_at or summarise_if functions to aggregate multiple variables simultaneously. For the example dataset you can do this as follows:

library(dplyr)
# summarising all non-grouping variables
df2 <- df1 %>% group_by(year, month) %>% summarise_all(sum)

# summarising a specific set of non-grouping variables
df2 <- df1 %>% group_by(year, month) %>% summarise_at(vars(x1, x2), sum)
df2 <- df1 %>% group_by(year, month) %>% summarise_at(vars(-date), sum)

# summarising a specific set of non-grouping variables using select_helpers
# see ?select_helpers for more options
df2 <- df1 %>% group_by(year, month) %>% summarise_at(vars(starts_with('x')), sum)
df2 <- df1 %>% group_by(year, month) %>% summarise_at(vars(matches('.*[0-9]')), sum)

# summarising a specific set of non-grouping variables based on condition (class)
df2 <- df1 %>% group_by(year, month) %>% summarise_if(is.numeric, sum)

The result of the latter two options:

    year month        x1         x2
   <dbl> <dbl>     <dbl>      <dbl>
1   2000     1 -73.58134  -92.78595
2   2000     2 -57.81334 -152.36983
3   2000     3 122.68758  153.55243
4   2000     4 450.24980  285.56374
5   2000     5 678.37867  384.42888
6   2000     6 792.68696  530.28694
7   2000     7 908.58795  452.31222
8   2000     8 710.69928  719.35225
9   2000     9 725.06079  914.93687
10  2000    10 770.60304  863.39337
# ... with 14 more rows

Note: summarise_each is deprecated in favor of summarise_all, summarise_at and summarise_if.

As mentioned in my comment above, you can also use the recast function from the reshape2-package:

library(reshape2)
recast(df1, year + month ~ variable, sum, id.var = c("date", "year", "month"))

which will give you the same result.

I think if you are looking for fullscreen only, no need to set geometry or maxsize etc.

You just need to do this:

-If you are working on ubuntu:

root=tk.Tk()
root.attributes('-zoomed', True)

-and if you are working on windows:

root.state('zoomed')

Now for toggling between fullscreen, for minimising it to taskbar you can use:

Root.iconify()

directly use

paragraph.add("\n");

to add an empty line.

I find that I do need the IP in order to configure /etc/hosts on the host system to point at services on the fresh VM.

Here's a rough version of what I use to fetch the IP. Let Vagrant do its SSH magic and ask the VM for its address; tweak for your needs.

new_ip=$(vagrant ssh -c "ip address show eth0 | grep 'inet ' | sed -e 's/^.*inet //' -e 's/\/.*$//'")

I just found this in the Vagrant Docs. Looks like they consider it a valid approach:

This will automatically assign an IP address from the reserved address space. The IP address can be determined by using vagrant ssh to SSH into the machine and using the appropriate command line tool to find the IP, such as ifconfig.

If you have downloaded Github Desktop Client 1.0.9 then the path for git.exe will be

C:\Users\Username\AppData\Local\GitHubDesktop\app-1.0.9\resources\app\git\cmd\git.exe

My version of user113716's answer. His removes a value if no match is found, which is not good.

var y = [1, 2, 3]
var removeItem = 2;

var i = $.inArray(removeItem,y)

if (i >= 0){
    y.splice(i, 1);
}

alert(y);

This now removes 1 item if a match is found, 0 if no matches are found.

How it works:

• $.inArray(value, array) is a jQuery function which finds the first index of a value in an array
• The above returns -1 if the value is not found, so check that i is a valid index before we do the removal. Removing index -1 means removing the last, which isn't helpful here.
• .splice(index, count) removes count number of values starting at index, so we just want a count of 1

Yet another trick (as of v1.6)

A=np.arange(1,10).reshape(3,3)
b=np.arange(3)

np.einsum('ij,i->ij',A,b)

I'm proficient with the numpy broadcasting (newaxis), but I'm still finding my way around this new einsum tool. So I had play around a bit to find this solution.

Timings (using Ipython timeit):

einsum: 4.9 micro
transpose: 8.1 micro
newaxis: 8.35 micro
dot-diag: 10.5 micro

Incidentally, changing a i to j, np.einsum('ij,j->ij',A,b), produces the matrix that Alex does not want. And np.einsum('ji,j->ji',A,b) does, in effect, the double transpose.

You can use the pluck method:

Word_relation::where('word_one', $word_id)->pluck('word_two')->toArray();

For more info on what methods are available for using with collection, you can you can check out the Laravel Documentation.

For modern browsers, the best solution is to use Promises.

The T doesn't really stand for anything. It is just the separator that the ISO 8601 combined date-time format requires. You can read it as an abbreviation for Time.

The Z stands for the Zero timezone, as it is offset by 0 from the Coordinated Universal Time (UTC).

Both characters are just static letters in the format, which is why they are not documented by the datetime.strftime() method. You could have used Q or M or Monty Python and the method would have returned them unchanged as well; the method only looks for patterns starting with % to replace those with information from the datetime object.

I've found that Spring's repeat annotation is useful for that kind of thing:

@Repeat(value = 10)

Latest (Spring Framework 4.3.11.RELEASE API) doc:

• org.springframework.test.annotation
• Unit Testing in Spring

  select t1.id, t1.count, SUM(t2.count) cumulative_sum
    from table t1 
        join table t2 on t1.id >= t2.id
    group by t1.id, t1.count

Step by step:

1- Given the following table:

select *
from table t1 
order by t1.id;

id  | count
 1  |  11
 2  |  12   
 3  |  13

2 - Get information by groups

select *
from table t1 
    join table t2 on t1.id >= t2.id
order by t1.id, t2.id;

id  | count | id | count
 1  | 11    | 1  |  11

 2  | 12    | 1  |  11
 2  | 12    | 2  |  12

 3  | 13    | 1  |  11
 3  | 13    | 2  |  12
 3  | 13    | 3  |  13

3- Step 3: Sum all count by t1.id group

select t1.id, t1.count, SUM(t2.count) cumulative_sum
from table t1 
    join table t2 on t1.id >= t2.id
group by t1.id, t1.count;


id  | count | cumulative_sum
 1  |  11   |    11
 2  |  12   |    23
 3  |  13   |    36

The envdir utility provides an easy way to do this. envdir uses files to represent environment variables, with file names mapping to env var names, and file contents mapping to env var values. If the file contents contain newlines, so will the env var.

See https://pypi.python.org/pypi/envdir

I used this command and it worked fine with me:

>git push -f origin master

But notice, that may delete some files you already have on the remote repo. That came in handy with me as the scenario was different; I was pushing my local project to the remote repo which was empty but the READ.ME

Just to give some examples. Let's say you modify the password for an user called 'alex'. You can modify this password in several ways. For instance:

mysql> update* user set password=PASSWORD('test!23') where user='alex'; 
mysql> flush privileges;

Here you used UPDATE. If you use INSERT, UPDATE or DELETE on grant tables directly you need use FLUSH PRIVILEGES in order to reload the grant tables.

Or you can modify the password like this:

mysql> set password for 'alex'@'localhost'= password('test!24');

Here it's not necesary to use "FLUSH PRIVILEGES;" If you modify the grant tables indirectly using account-management statements such as GRANT, REVOKE, SET PASSWORD, or RENAME USER, the server notices these changes and loads the grant tables into memory again immediately.

Nano is 10^-9 and milli 10^-3. Hence, we can use the three first characters of nanoseconds to get the milliseconds:

date +%s%3N

From man date:

%N nanoseconds (000000000..999999999)

%s seconds since 1970-01-01 00:00:00 UTC

Source: Server Fault's How do I get the current Unix time in milliseconds in Bash?.

Try: 

SELECT EXTRACT(EPOCH FROM (timestamp_B - timestamp_A))
FROM TableA

Details here: EXTRACT.

I have provided two approaches to solve the same issue,

Solution 1: This approach includes 2 steps, first create a temporary table with specified data type, next insert the value from the existing data table.

CREATE TABLE #TempStudent(tempID  int, tempName  varchar(MAX) )
INSERT INTO #TempStudent(tempID, tempName) SELECT id, studName FROM students where id =1

SELECT * FROM #TempStudent

Solution 2: This approach is simple, where you can directly insert the values to temporary table, where automatically the system take care of creating the temp table with the same data type of original table.

SELECT id, studName  INTO #TempStudent FROM students where id =1

SELECT * FROM #TempStudent

I found that you can do it like this:

.submit .btn input_x000D_
{_x000D_
   padding:11px 28px 12px 14px;_x000D_
   background:#004990;_x000D_
   border:none;_x000D_
    color:#fff;_x000D_
}_x000D_
_x000D_
 .submit .btn_x000D_
 {_x000D_
     border:none;_x000D_
     color:#fff;_x000D_
     font-family: 'Open Sans', sans-serif;_x000D_
     font-size:1em;_x000D_
     min-width:96px;_x000D_
     display:inline-block;_x000D_
     position:relative;_x000D_
 }_x000D_
_x000D_
.submit .btn:after_x000D_
{_x000D_
    content:">";_x000D_
    width:6px;_x000D_
    height:17px;_x000D_
    position:absolute;_x000D_
    right:36px;_x000D_
    color:#fff;_x000D_
    top:7px;_x000D_
}

<div class="submit">_x000D_
  <div class="btn">_x000D_
     <input value="Send" type="submit" />_x000D_
  </div>_x000D_
</div>

You need to have a div parent that takes the padding and the :after. The first parent needs to be relative and the second div should be absolute so you can set the position of the after.

This is an easy way to get a successful response from the server like PHP echo otherwise an error message.

BufferedReader br = null;
if (conn.getResponseCode() == 200) {
    br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
    String strCurrentLine;
        while ((strCurrentLine = br.readLine()) != null) {
               System.out.println(strCurrentLine);
        }
} else {
    br = new BufferedReader(new InputStreamReader(conn.getErrorStream()));
    String strCurrentLine;
        while ((strCurrentLine = br.readLine()) != null) {
               System.out.println(strCurrentLine);
        }
}

I alluded to some python code in a comment to the answer from @alex lehmann's , so am posting it here.

form.reset() is a DOM element method (not one on the jQuery object), so you need:

$("#client.frm")[0].reset();
//faster version:
$("#client")[0].reset();

Or without jQuery:

document.getElementById("client").reset();

telnet ServerName 80

GET /index.html?
?

? means 'return', you need to hit return twice

Try:

select distinct T1.id
  from TABLE1 T1
 where not exists (select distinct T2.id
                     from TABLE2 T2
                    where T2.id = T1.id)

You can use the Window object and access it everwhere. example window.defaultTitle = "my title"; then you can access window.defaultTitle without importing anything.

While Ralphs Answer provides an elegant solution, with Spring Security 3.2 you no longer need to implement your own ArgumentResolver.

If you have a UserDetails implementation CustomUser, you can just do this:

@RequestMapping("/messages/inbox")
public ModelAndView findMessagesForUser(@AuthenticationPrincipal CustomUser customUser) {

    // .. find messages for this User and return them...
}

See Spring Security Documentation: @AuthenticationPrincipal

I was facing similar kind of problem.There is image of error attached.Error is highlighted in red. Turning off the Instant run removed error for Android Studio 2.3 and 3.1.4.

I am assuming that active events in a time period means at least one day of the event falls inside the time period. This is a simple "find overlapping dates" problem and there is a generic solution:

-- [@d1, @d2] is the date range to check against
SELECT * FROM events WHERE @d2 >= start AND end >= @d1

Some tests:

-- list of events
SELECT * FROM events;
+------+------------+------------+
| id   | start      | end        |
+------+------------+------------+
|    1 | 2013-06-14 | 2013-06-14 |
|    2 | 2013-06-15 | 2013-08-21 |

|    4 | 2013-07-01 | 2013-07-10 |
|    5 | 2013-07-30 | 2013-07-31 |
+------+------------+------------+

-- events between [2013-06-01, 2013-06-15]
SELECT * FROM events WHERE '2013-06-15' >= start AND end >= '2013-06-01';
+------+------------+------------+
| id   | start      | end        |
+------+------------+------------+
|    1 | 2013-06-14 | 2013-06-14 |
|    2 | 2013-06-15 | 2013-08-21 |
+------+------------+------------+

-- events between [2013-06-16, 2013-06-30]
SELECT * FROM events WHERE '2013-06-30' >= start AND end >= '2013-06-16';

it should. Typically that's how you do multiple selectors. Otherwise it may not like you trying to assign the return values of three uploads to the same var.

I would suggest using .each or maybe push the returns to an array rather than assigning them to that value.

The query you are after will be

SELECT word FROM table WHERE word NOT LIKE '%a%' AND word NOT LIKE '%b%'

Note that, in Java 8, 'ia' above must be Integer[] and not int[]. Arrays.asList() of an int array returns a list with a single element. When using OP's code snippet, the compiler will catch the issue, but some methods (e.g. Collections.shuffle()) will silently fail to do what you expect.

Using as reference this page and the documentation (which seems to have greatly improved since the last time I looked), I put together the following real(-ish) world demo which uses 4 of the 5 flavours of provider; Value, Constant, Factory and full blown Provider.

HTML:

<div ng-controller="mainCtrl as main">
    <h1>{{main.title}}*</h1>
    <h2>{{main.strapline}}</h2>
    <p>Earn {{main.earn}} per click</p>
    <p>You've earned {{main.earned}} by clicking!</p>
    <button ng-click="main.handleClick()">Click me to earn</button>
    <small>* Not actual money</small>
</div>

app

var app = angular.module('angularProviders', []);

// A CONSTANT is not going to change
app.constant('range', 100);

// A VALUE could change, but probably / typically doesn't
app.value('title', 'Earn money by clicking');
app.value('strapline', 'Adventures in ng Providers');

// A simple FACTORY allows us to compute a value @ runtime.
// Furthermore, it can have other dependencies injected into it such
// as our range constant.
app.factory('random', function randomFactory(range) {
    // Get a random number within the range defined in our CONSTANT
    return Math.random() * range;
});

// A PROVIDER, must return a custom type which implements the functionality 
// provided by our service (see what I did there?).
// Here we define the constructor for the custom type the PROVIDER below will 
// instantiate and return.
var Money = function(locale) {

    // Depending on locale string set during config phase, we'll
    // use different symbols and positioning for any values we 
    // need to display as currency
    this.settings = {
        uk: {
            front: true,
            currency: '£',
            thousand: ',',
            decimal: '.'
        },
        eu: {
            front: false,
            currency: '€',
            thousand: '.',
            decimal: ','
        }
    };

    this.locale = locale;
};

// Return a monetary value with currency symbol and placement, and decimal 
// and thousand delimiters according to the locale set in the config phase.
Money.prototype.convertValue = function(value) {

    var settings = this.settings[this.locale],
        decimalIndex, converted;

    converted = this.addThousandSeparator(value.toFixed(2), settings.thousand);

    decimalIndex = converted.length - 3;

    converted = converted.substr(0, decimalIndex) +
        settings.decimal +
        converted.substr(decimalIndex + 1);    

    converted = settings.front ?
            settings.currency + converted : 
            converted + settings.currency; 

    return converted;   
};

// Add supplied thousand separator to supplied value
Money.prototype.addThousandSeparator = function(value, symbol) {
   return value.toString().replace(/\B(?=(\d{3})+(?!\d))/g, symbol);
};

// PROVIDER is the core recipe type - VALUE, CONSTANT, SERVICE & FACTORY
// are all effectively syntactic sugar built on top of the PROVIDER construct
// One of the advantages of the PROVIDER is that we can configure it before the
// application starts (see config below).
app.provider('money', function MoneyProvider() {

    var locale;

    // Function called by the config to set up the provider
    this.setLocale = function(value) {
        locale = value;   
    };

    // All providers need to implement a $get method which returns
    // an instance of the custom class which constitutes the service
    this.$get = function moneyFactory() {
        return new Money(locale);
    };
});

// We can configure a PROVIDER on application initialisation.
app.config(['moneyProvider', function(moneyProvider) {
    moneyProvider.setLocale('uk');
    //moneyProvider.setLocale('eu'); 
}]);

// The ubiquitous controller
app.controller('mainCtrl', function($scope, title, strapline, random, money) {

    // Plain old VALUE(s)
    this.title = title;
    this.strapline = strapline;

    this.count = 0;

    // Compute values using our money provider    
    this.earn = money.convertValue(random); // random is computed @ runtime
    this.earned = money.convertValue(0);

    this.handleClick = function() { 
        this.count ++;
        this.earned = money.convertValue(random * this.count);
    };
});

Working demo.

What you're doing is appending a "1" (the string) to your URL. If you want page 1.html link to page 2.html you need to take the 1 out of the string, add one to it, then reassemble the string.

Why not do something like this:

var url = 'http://mywebsite.com/1.html';
var pageNum = parseInt( url.split("/").pop(),10 );
var nextPage = 'http://mywebsite.com/'+(pageNum+1)+'.html';

nextPage will contain the url http://mywebsite.com/2.html in this case. Should be easy to put in a function if needed.

Java does not have the exact syntax but as of JDK-8, we have the Optional API with various methods at our disposal. So, the C# version with the use of null conditional operator:

return person?.getName()?.getGivenName(); 

can be written as follows in Java with the Optional API:

 return Optional.ofNullable(person)
                .map(e -> e.getName())
                .map(e -> e.getGivenName())
                .orElse(null);

if any of person, getName or getGivenName is null then null is returned.

coalesce is supported in both Oracle and SQL Server and serves essentially the same function as nvl and isnull. (There are some important differences, coalesce can take an arbitrary number of arguments, and returns the first non-null one. The return type for isnull matches the type of the first argument, that is not true for coalesce, at least on SQL Server.)

The jquery ajax method returns a XMLHttpRequest object. You can use this object to cancel the request.

The XMLHttpRequest has a abort method, which cancels the request, but if the request has already been sent to the server then the server will process the request even if we abort the request but the client will not wait for/handle the response.

The xhr object also contains a readyState which contains the state of the request(UNSENT-0, OPENED-1, HEADERS_RECEIVED-2, LOADING-3 and DONE-4). we can use this to check whether the previous request was completed.

$(document).ready(
    var xhr;

    var fn = function(){
        if(xhr && xhr.readyState != 4){
            xhr.abort();
        }
        xhr = $.ajax({
            url: 'ajax/progress.ftl',
            success: function(data) {
                //do something
            }
        });
    };

    var interval = setInterval(fn, 500);
);

I recently had to build something similar. You can check it out in the snippet below.

The version I had to build uses the same button to start and stop the spinner, but you can manipulate to code if you have a button to start the spin and a different button to stop the spin

Basically, my code looks like this...

I use the following way to handle the many-to-many relationship where only foreign keys are involved.

So for inserting:

public void InsertStudentClass (long studentId, long classId)
{
    using (var context = new DatabaseContext())
    {
        Student student = new Student { StudentID = studentId };
        context.Students.Add(student);
        context.Students.Attach(student);

        Class class = new Class { ClassID = classId };
        context.Classes.Add(class);
        context.Classes.Attach(class);

        student.Classes = new List<Class>();
        student.Classes.Add(class);

        context.SaveChanges();
    }
}

For deleting,

public void DeleteStudentClass(long studentId, long classId)
{
    Student student = context.Students.Include(x => x.Classes).Single(x => x.StudentID == studentId);

    using (var context = new DatabaseContext())
    {
        context.Students.Attach(student);
        Class classToDelete = student.Classes.Find(x => x.ClassID == classId);
        if (classToDelete != null)
        {
            student.Classes.Remove(classToDelete);
            context.SaveChanges();
        }
    }
}

If obj Is Nothing Then
    ' need to initialize obj: '
    Set obj = ...
Else
    ' obj already set / initialized. '
End If

Or, if you prefer it the other way around:

If Not obj Is Nothing Then
    ' obj already set / initialized. '
Else
    ' need to initialize obj: '
    Set obj = ...
End If

you need declare resources in dispatcher servelet file.below is two declarations

<mvc:annotation-driven />
<mvc:resources location="/resources/" mapping="/resources/**" />

I ended here, because I googled for "python first and last element of array", and found everything else but this. So here's the answer to the title question:

a = [1,2,3]
a[0] # first element (returns 1)
a[-1] # last element (returns 3)

Try this

var store = dtpDateTimePicker.Value.Date;

store can be anything entity object etc.

The runas command does not allow a password on its command line. This is by design (and also the reason you cannot pipe a password to it as input). Raymond Chen says it nicely:

The RunAs program demands that you type the password manually. Why doesn't it accept a password on the command line?

This was a conscious decision. If it were possible to pass the password on the command line, people would start embedding passwords into batch files and logon scripts, which is laughably insecure.

In other words, the feature is missing to remove the temptation to use the feature insecurely.

If you apply utf8_encode() to an already UTF8 string it will return a garbled UTF8 output.

I made a function that addresses all this issues. It´s called Encoding::toUTF8().

You dont need to know what the encoding of your strings is. It can be Latin1 (ISO8859-1), Windows-1252 or UTF8, or the string can have a mix of them. Encoding::toUTF8() will convert everything to UTF8.

I did it because a service was giving me a feed of data all messed up, mixing those encodings in the same string.

Usage:

require_once('Encoding.php'); 
use \ForceUTF8\Encoding;  // It's namespaced now.

$utf8_string = Encoding::toUTF8($mixed_string);

$latin1_string = Encoding::toLatin1($mixed_string);

I've included another function, Encoding::fixUTF8(), which will fix every UTF8 string that looks garbled product of having been encoded into UTF8 multiple times.

Usage:

require_once('Encoding.php'); 
use \ForceUTF8\Encoding;  // It's namespaced now.

$utf8_string = Encoding::fixUTF8($garbled_utf8_string);

Examples:

echo Encoding::fixUTF8("Fédération Camerounaise de Football");
echo Encoding::fixUTF8("Fédération Camerounaise de Football");
echo Encoding::fixUTF8("FÃÂédÃÂération Camerounaise de Football");
echo Encoding::fixUTF8("Fédération Camerounaise de Football");

will output:

Fédération Camerounaise de Football
Fédération Camerounaise de Football
Fédération Camerounaise de Football
Fédération Camerounaise de Football

Like @Sunkas wrote, performSelector:withObject:afterDelay: is the pendant to the dispatch_after just that it is shorter and you have the normal objective-c syntax. If you need to pass arguments to the block you want to delay, you can just pass them through the parameter withObject and you will receive it in the selector you call:

[self performSelector:@selector(testStringMethod:) 
           withObject:@"Test Test" 
           afterDelay:0.5];

- (void)testStringMethod:(NSString *)string{
    NSLog(@"string  >>> %@", string);
}

If you still want to choose yourself if you execute it on the main thread or on the current thread, there are specific methods which allow you to specify this. Apples Documentation tells this:

If you want the message to be dequeued when the run loop is in a mode other than the default mode, use the performSelector:withObject:afterDelay:inModes: method instead. If you are not sure whether the current thread is the main thread, you can use the performSelectorOnMainThread:withObject:waitUntilDone: or performSelectorOnMainThread:withObject:waitUntilDone:modes: method to guarantee that your selector executes on the main thread. To cancel a queued message, use the cancelPreviousPerformRequestsWithTarget: or cancelPreviousPerformRequestsWithTarget:selector:object: method.

If you're on OSX you can also find it your keychain. Your developer and distribution certificates have your Team ID in them.

Applications -> Utilities -> Keychain Access.

Under the 'login' Keychain, go into the 'Certificates' category.

Scroll to find your development or distribution certificate. They will read:

iPhone Distribution: Team Name (certificate id)

or

iPhone Developer: Team Name (certificate id)

Simply double-click on the item, and the

"Organizational Unit"

is the "Team ID"

Note that this is the only way to find your

"Personal team" ID

You can not find the "Personal team" ID on the Apple web interface.

For example, if you are automating a build from say Unity, during development you'll want it to appear in Xcode as your "Personal team" - this is the only way to get that value.

I have given different ways to create DataFrame from text file

You should change your parenthesis to

while((c = getchar()) != EOF)

Because the "=" operator has a lower precedence than the "!=" operator. Then you will get the expected results. Your expression is equal to

while (c = (getchar()!= EOF))

You are getting the two 1's as output, because you are making the comparison "c!=EOF". This will always become one for the character you entered and then the "\n" that follows by hitting return. Except for the last comparison where c really is EOF it will give you a 0.

EDIT about EOF: EOF is typically -1, but this is not guaranteed by the standard. The standard only defines about EOF in section 7.19.1:

EOF which expands to an integer constant expression, with type int and a negative value, that is returned by several functions to indicate end-of-file, that is, no more input from a stream;

It is reasonable to assume that EOF equals -1, but when using EOF you should not test against the specific value, but rather use the macro.

ID % 2 is checking what the remainder is if you divide ID by 2. If you divide an even number by 2 it will always have a remainder of 0. Any other number (odd) will result in a non-zero value. Which is what is checking for.

Obj-C has much more dynamic capabilities in the language itself, whereas C++ is more focused on compile-time capabilities with some dynamic capabilities.

In, C++ parametric polymorphism is checked at compile-time, whereas in Obj-C, parametric polymorphism is achieved through dynamic dispatch and is not checked at compile-time.

Obj-C is very dynamic in nature. You can add methods to a class during run-time. Also, it has introspection at run-time to look at classes. In C++, the definition of class can't change, and all introspection must be done at compile-time. Although, the dynamic nature of Obj-C could be achieved in C++ using a map of functions(or something like that), it is still more verbose than in Obj-C.

In C++, there is a lot more checks that can be done at compile time. For example, using a variant type(like a union) the compiler can enforce that all cases are written or handled. So you don't forget about handling the edge cases of a problem. However, all these checks come at a price when compiling. Obj-C is much faster at compiling than C++.

Full Chrome remote debugging of Android native browser on a Galaxy S6 on Android 5.1.1:

1. Enable USB Debugging on phone (Settings, about, rapidly tap build number, developer settings, USB debugging)
2. Open "Internet"
3. Navigate to 'about:debug' (you will see an error)
4. MORE menu > Settings > Debug > Remote Debugging
5. Attach phone to computer with USB cable
6. On the phone, in the Internet web browser, open the site you want to debug
7. Open Chrome on computer
8. Navigate to 'chrome://inspect'
9. Click inspect on the browser tab you want to inspect

The Galaxy S5 devices shows in Chrome but the tabs only show after you restart. After restarting and attempting to attach, the mobile browser crashes.

Since I am sorting alphabetically on a string field and NOT by ID, the Count(*) and DCOUNT() approaches didn't work for me. My solution was to write a function that returns the Row Number:

Option Compare Database
Option Explicit
Private Rst As Recordset

Public Function GetRowNum(ID As Long) As Long
  If Rst Is Nothing Then
    Set Rst = CurrentDb.OpenRecordset("SELECT ID FROM FileList ORDER BY RealName")
  End If
  Rst.FindFirst "ID=" & ID
  GetRowNum = Rst.AbsolutePosition + 1
' Release the Rst 1 sec after it's last use
'------------------------------------------
  SetTimer Application.hWndAccessApp, 1, 1000, AddressOf ReleaseRst  
End Function


Private Sub ReleaseRst(ByVal hWnd As LongPtr, ByVal uMsg As Long, ByVal nIDEEvent As Long, ByVal dwTime As Long)
  KillTimer Application.hWndAccessApp, 1 
  Set Rst = Nothing
End Sub

int[] arr = {111, 111, 110, 101, 101, 102, 115, 112};

/* for ascending order */

System.out.println(Arrays.toString(getSortedArray(arr)));
/*for descending order */
System.out.println(Arrays.toString(getSortedArray(arr)));

private int[] getSortedArray(int[] k){  

        int localIndex =0;
        for(int l=1;l<k.length;l++){
            if(l>1){
                localIndex = l;
                while(true){
                    k = swapelement(k,l);
                    if(l-- == 1)
                        break;
                }
                l = localIndex;
            }else
                k = swapelement(k,l);   
        }
        return k;
    }

    private int[] swapelement(int[] ar,int in){
        int temp =0;
        if(ar[in]<ar[in-1]){
            temp = ar[in];
            ar[in]=ar[in-1];
            ar[in-1] = temp;
        }

        return ar;
    }

private int[] getDescOrder(int[] byt){
        int s =-1;
        for(int i = byt.length-1;i>=0;--i){
              int k = i-1;
              while(k >= 0){
                  if(byt[i]>byt[k]){
                      s = byt[k];
                      byt[k] = byt[i];
                      byt[i] = s;
                  }
                  k--;
              }
           }
        return byt;
    }

output:-
ascending order:- 101, 101, 102, 110, 111, 111, 112, 115

descending order:- 115, 112, 111, 111, 110, 102, 101, 101

Using the principle of the idea user2620505 got result with implementation of addClass:

...
open: function(){
    $('.ui-dialog-titlebar-close').addClass('ui-button ui-widget ui-state-default ui-corner-all ui-button-icon-only');
    $('.ui-dialog-titlebar-close').append('<span class="ui-button-icon-primary ui-icon ui-icon-closethick"></span><span class="ui-button-text">close</span>');
}, 
...

If English is bad forgive me, I am using Google Translate.

I have created a simple MySQL procedure as given below:

DELIMITER //
CREATE PROCEDURE GetAllListings()
 BEGIN
 SELECT nid, type, title  FROM node where type = 'lms_listing' order by nid desc;
END //
DELIMITER;

Kindly follow this. After the procedure created, you can see the same and execute it.

When FIND returns #VALUE!, it is an error, not a string, so you can't compare FIND(...) with "#VALUE!", you need to check if FIND returns an error with ISERROR. Also FIND can work on multiple characters.

So a simplified and working version of your formula would be:

=IF(ISERROR(FIND("abc",A1))=FALSE, "Green", IF(ISERROR(FIND("xyz",A1))=FALSE, "Yellow", "Red"))

Or, to remove the double negations:

=IF(ISERROR(FIND("abc",A1)), IF(ISERROR(FIND("xyz",A1)), "Red", "Yellow"),"Green")

Your svn merge syntax is wrong.

You want to checkout a working copy of trunk and then use the svn merge --reintegrate option:

$ pwd
/home/user/project-trunk

$ svn update  # (make sure the working copy is up to date)
At revision <N>.

$ svn merge --reintegrate ^/project/branches/branch_1
--- Merging differences between repository URLs into '.':
U    foo.c
U    bar.c
 U   .

$ # build, test, verify, ...

$ svn commit -m "Merge branch_1 back into trunk!"
Sending        .
Sending        foo.c
Sending        bar.c
Transmitting file data ..
Committed revision <N+1>.

See the SVN book chapter on merging for more details.

Note that at the time it was written, this was the right answer (and was accepted), but things have moved on. See the answer of topek, and http://subversion.apache.org/docs/release-notes/1.8.html#auto-reintegrate

I thinks it is vary helpful way.

models.py

from django.db import models
class User(models.Model):
    user_name = models.CharField(max_length=100)
    password = models.CharField(max_length=32)

forms.py

from django import forms
from Admin.models import *
class User_forms(forms.ModelForm):
    class Meta:
        model= User
        fields=[
           'user_name',
           'password'
            ]
       widgets = {
      'password': forms.PasswordInput()
         }

If you specify CSS attributes for your body element it should apply to anything within <body></body> so long as you don't override them later in the stylesheet.

you can use :

$('#timePicker').datetimepicker({
        format:'d.m.Y H:i',
        minDate: ge_today_date(new Date())
});

 function ge_today_date(date) {
     var day = date.getDate();
     var month = date.getMonth() + 1;
     var year = date.getFullYear().toString().slice(2);
     return day + '-' + month + '-' + year;
 }

I found a very simple solution to the problem. I simply created two GridViews. The first GridView called a DataSource with a query that was designed to return no rows. It simply contained the following:

    <Columns>
        <asp:TemplateField HeaderStyle-HorizontalAlign="Left">
            <HeaderTemplate>

               <asp:Label ID="lbl0" etc.>  </asp:Label>
               <asp:Label ID="lbl1" etc.>  </asp:Label>

            </HeaderTemplate>
        </asp:TemplateField>
    </Columns>

Then I created a div with the following characteristics and I place a GridView inside of it with ShowHeader="false" so that the top row is the same size as all the other rows.

<div style="overflow: auto; height: 29.5em; width: 100%">
    <asp:GridView ID="Rollup" runat="server" ShowHeader="false" DataSourceID="ObjectDataSource">
        <Columns>
            <asp:TemplateField HeaderStyle-HorizontalAlign="Left">
                <ItemTemplate>

               <asp:Label ID="lbl0" etc.>  </asp:Label>
               <asp:Label ID="lbl1" etc.>  </asp:Label>

                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>
</div>

Why don't you try converting its type from a tuple to a list and vice versa.

level1 = (
     (1,1,1,1,1,1)
     (1,0,0,0,0,1)
     (1,0,0,0,0,1)
     (1,0,0,0,0,1)
     (1,0,0,0,0,1)
     (1,1,1,1,1,1))

print(level1)

level1 = list(level1)

print(level1)

level1 = tuple(level1)

print(level1)

Personally I like the proposal of the bind operator :: and would then combine it with the solution @d13 mentioned but for now stick with @d13 's answer where you use the export keyword for your class and put the private functions in the module.

there is one more solution tough which hasn't been mentioned here that follows are more functional approach and would allow it to have all the private props/methods within the class.

Private.js

export const get = state => key => state[key];
export const set = state => (key,value) => { state[key] = value; }

Test.js

import { get, set } from './utils/Private'
export default class Test {
  constructor(initialState = {}) {
    const _set = this.set = set(initialState);
    const _get = this.get = get(initialState);

    this.set('privateMethod', () => _get('propValue'));
  }

  showProp() {
    return this.get('privateMethod')();
  }
}

let one = new Test({ propValue: 5});
let two = new Test({ propValue: 8});
two.showProp(); // 8
one.showProp(); // 5

comments on it would be appreciated.

If you need generate numbers with intervals, it can be just like that:

Integer[] arr = new Integer[((int) (Math.random() * (16 - 30) + 30))];
for (int i = 0; i < arr.length; i++) {
arr[i] = i;
}
Collections.shuffle(Arrays.asList(arr));
System.out.println(Arrays.toString(arr));`

The result:

[1, 10, 2, 4, 9, 8, 7, 13, 18, 17, 5, 21, 12, 16, 23, 20, 6, 0, 22, 14, 24, 15, 3, 11, 19]

Note:

If you need that the zero does not leave you could put an "if"

It can also be done with an IsoDateTimeConverter instance, without changing global formatting settings:

string json = JsonConvert.SerializeObject(yourObject,
    new IsoDateTimeConverter() { DateTimeFormat = "yyyy-MM-dd HH:mm:ss" });

This uses the JsonConvert.SerializeObject overload that takes a params JsonConverter[] argument.

I see that this post is old. But in version CI v3 here is the answer:

echo $this->uri->uri_string();

Thanks

1. Create the empty database manually.
2. Change the "Integrated Security" in connection string from "true" to "false".
3. Be sure your user is sysadmin in your new database

Now I hope you can execute update-database successfully.

In a more general way you can use "INTERVAL". Here some examples:

1) add a day

select sysdate + INTERVAL '1' DAY from dual;

2) add 20 days

select sysdate + INTERVAL '20' DAY from dual;

2) add some minutes

select sysdate + INTERVAL '15' MINUTE from dual;

If you are using Express, the cleanest complete answer is this

const express = require('express')
const app     = express()

app.get('*', (req, res) => {
  // REDIRECT goes here
  res.redirect('https://www.YOUR_URL.com/')
})

app.set('port', (process.env.PORT || 3000))
const server = app.listen(app.get('port'), () => {})

This error

Failure [INSTALL_FAILED_OLDER_SDK]

Means that you're trying to install an app that has a higher minSdkVersion specified in its manifest than the device's API level. Change that number to 8 and it should work. I'm not sure about the other error, but it may be related to this one.

tl;dr

LocalDate.now()       // Capture the date-only value current in the JVM’s current default time zone.
         .getYear()   // Extract the year number from that date.

2018

java.time

Both the java.util.Date and java.util.Calendar classes are legacy, now supplanted by the java.time framework built into Java 8 and later.

A time zone is crucial in determining a date. For any given moment, the date varies around the globe by zone. For example, a few minutes after midnight in Paris France is a new day while still “yesterday” in Montréal Québec.

If no time zone is specified, the JVM implicitly applies its current default time zone. That default may change at any moment, so your results may vary. Better to specify your desired/expected time zone explicitly as an argument.

Specify a proper time zone name in the format of continent/region, such as America/Montreal, Africa/Casablanca, or Pacific/Auckland. Never use the 3-4 letter abbreviation such as EST or IST as they are not true time zones, not standardized, and not even unique(!).

ZoneId z = ZoneId.of( "Africa/Tunis" ) ;  

If you want only the date without time-of-day, use LocalDate. This class lacks time zone info but you can specify a time zone to determine the current date.

ZoneId zoneId = ZoneId.of( "America/Montreal" );
LocalDate localDate = LocalDate.now( zoneId );

You can get the various pieces of information with getYear, getMonth, and getDayOfMonth. You will actually get the year number with java.time!

int year = localDate.getYear();

2016

If you want a date-time instead of just a date, use ZonedDateTime class.

ZonedDateTime zdt = ZonedDateTime.now( zoneId ) ;

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old date-time classes such as java.util.Date, .Calendar, & java.text.SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations.

Much of the java.time functionality is back-ported to Java 6 & Java 7 in ThreeTen-Backport and further adapted to Android in ThreeTenABP (see How to use…).

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

USCOUNTER=$(grep -c "^US " "$FILE")

You'll have to include/require the class anyway, otherwise PHP won't know about the namespace.
You don't necessary have to do it in the same file though. You can do it in a bootstrap file for example. (or use an autoloader, but that's not the topic actually)

For the instance:

if (obj is IMyInterface) {}

For the class:

Check if typeof(MyClass).GetInterfaces() contains the interface.

Getting into a non-password protected Java keystore and changing the password can be done with a help of Java programming language itself.

That article contains the code for that:

thetechawesomeness.ideasmatter.info

You can use InitialCatalog Property or builder["Database"] works as well. I tested it with different case and it still works.

Whenever you want to extend the properties of User.Identity with any additional properties like the question above, add these properties to the ApplicationUser class first like so:

public class ApplicationUser : IdentityUser
{
    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
    {
        // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
        var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
        // Add custom user claims here
        return userIdentity;
    }

    // Your Extended Properties
    public long? OrganizationId { get; set; }
}

Then what you need is to create an extension method like so (I create mine in an new Extensions folder):

namespace App.Extensions
{
    public static class IdentityExtensions
    {
        public static string GetOrganizationId(this IIdentity identity)
        {
            var claim = ((ClaimsIdentity)identity).FindFirst("OrganizationId");
            // Test for null to avoid issues during local testing
            return (claim != null) ? claim.Value : string.Empty;
        }
    }
}

When you create the Identity in the ApplicationUser class, just add the Claim -> OrganizationId like so:

    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
    {
        // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
        var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
        // Add custom user claims here => this.OrganizationId is a value stored in database against the user
        userIdentity.AddClaim(new Claim("OrganizationId", this.OrganizationId.ToString()));

        return userIdentity;
    }

Once you added the claim and have your extension method in place, to make it available as a property on your User.Identity, add a using statement on the page/file you want to access it:

in my case: using App.Extensions; within a Controller and @using. App.Extensions withing a .cshtml View file.

EDIT:

What you can also do to avoid adding a using statement in every View is to go to the Views folder, and locate the Web.config file in there. Now look for the <namespaces> tag and add your extension namespace there like so:

<add namespace="App.Extensions" />

Save your file and you're done. Now every View will know of your extensions.

You can access the Extension Method:

var orgId = User.Identity.GetOrganizationId();

Actually this one solved my problem:

-(void) tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {

NSSet *visibleSections = [NSSet setWithArray:[[tableView indexPathsForVisibleRows] valueForKey:@"section"]];
if (visibleSections) {
    // hide the activityIndicator/Loader
}}

You can easily delete the duplicate records from this code..

$qry = mysql_query("SELECT * from cities");
while($qry_row = mysql_fetch_array($qry))
{
$qry2 = mysql_query("SELECT * from cities2 where city = '".$qry_row['city']."'");

if(mysql_num_rows($qry2) > 1){
    while($row = mysql_fetch_array($qry2)){
        $city_arry[] = $row;

        }

    $total = sizeof($city_arry) - 1;
        for($i=1; $i<=$total; $i++){


            mysql_query( "delete from cities2 where town_id = '".$city_arry[$i][0]."'");

            }
    }
    //exit;
}

You should use thenReturn or doReturn when you know the return value at the time you mock a method call. This defined value is returned when you invoke the mocked method.

thenReturn(T value) Sets a return value to be returned when the method is called.

@Test
public void test_return() throws Exception {
    Dummy dummy = mock(Dummy.class);
    int returnValue = 5;

    // choose your preferred way
    when(dummy.stringLength("dummy")).thenReturn(returnValue);
    doReturn(returnValue).when(dummy).stringLength("dummy");
}

Answer is used when you need to do additional actions when a mocked method is invoked, e.g. when you need to compute the return value based on the parameters of this method call.

Use doAnswer() when you want to stub a void method with generic Answer.

Answer specifies an action that is executed and a return value that is returned when you interact with the mock.

@Test
public void test_answer() throws Exception {
    Dummy dummy = mock(Dummy.class);
    Answer<Integer> answer = new Answer<Integer>() {
        public Integer answer(InvocationOnMock invocation) throws Throwable {
            String string = invocation.getArgumentAt(0, String.class);
            return string.length() * 2;
        }
    };

    // choose your preferred way
    when(dummy.stringLength("dummy")).thenAnswer(answer);
    doAnswer(answer).when(dummy).stringLength("dummy");
}

As the others mentioned you can change the SubSystem to Console and the error will go away.

Or if you want to keep the Windows subsystem you can just hint at what your entry point is, because you haven't defined ___tmainCRTStartup. You can do this by adding the following to Properties -> Linker -> Command line:

/ENTRY:"mainCRTStartup"

This way you get rid of the console window.

>>> r = re.compile("([a-zA-Z]+)([0-9]+)")
>>> m = r.match("foobar12345")
>>> m.group(1)
'foobar'
>>> m.group(2)
'12345'

So, if you have a list of strings with that format:

import re
r = re.compile("([a-zA-Z]+)([0-9]+)")
strings = ['foofo21', 'bar432', 'foobar12345']
print [r.match(string).groups() for string in strings]

Output:

[('foofo', '21'), ('bar', '432'), ('foobar', '12345')]

1. Click Ctrl + h or Search -> Replace on the top menu
2. Under the Search Mode group, select Regular expression

4. In the Replace with text field, type ],\n
5. Click Replace All

Please be careful about time/zone if you set it to save dates in database, as I got an issue when I compared dates from mysql that converted to timestamp using strtotime. you must use exactly same time/zone before converting date to timestamp otherwise, strtotime() will use default server timezone.

Please see this example: https://3v4l.org/BRlmV

function getthistime($type, $modify = null) {
    $now = new DateTime(null, new DateTimeZone('Asia/Baghdad'));
    if($modify) {
        $now->modify($modify);
    }
    if(!isset($type) || $type == 'datetime') {
        return $now->format('Y-m-d H:i:s');
    }
    if($type == 'time') {
        return $now->format('H:i:s');
    }
    if($type == 'timestamp') {
        return $now->getTimestamp();
    }
}
function timestampfromdate($date) {
    return DateTime::createFromFormat('Y-m-d H:i:s', $date, new DateTimeZone('Asia/Baghdad'))->getTimestamp();
}

echo getthistime('timestamp')."--".
    timestampfromdate(getthistime('datetime'))."--".
    strtotime(getthistime('datetime'));

//getthistime('timestamp') == timestampfromdate(getthistime('datetime')) (true)
//getthistime('timestamp') == strtotime(getthistime('datetime')) (false)

It works for me.

public class Program
{
    public static void main(String[] args) {
        String str = "This is a string.\nThis is a long string.";
        str = str.replaceAll("(\r\n|\n)", "<br />");
        System.out.println(str);
    }
}

Result:

This is a string.<br />This is a long string.

Your problem is somewhere else.

p{
line-height: 20px;
width: 157px;
white-space: nowrap; 
overflow: hidden;
text-overflow: ellipsis;
}

or we can restrict the lines by using and height and overflow.

If you want to extract from a tag then

$('.dep_buttons').text().substr(0,25)

With the mouseover event,

$(this).text($(this).text().substr(0, 25));

The above will extract the text of a tag, then extract again assign it back.

For Windows user:

After installing Ruby 2.2.3 (+ rubygems 2.5.1) successfully on a test machine with access to the internet, I had this SSL error when I installed bundler on a production machine, within the network.

As I had network access limitations, and there was no way to change the settings for SSL access, and based on the error messages, I performed the steps below to be able to finish the installation of the bundler (this may sound crazy, but it worked...).

Through a machine with unrestricted access to the internet, downloaded the following files:

• spec.4.8.gz (http://rubygems.global.ssl.fastly.net/spec.4.8.gz)
• latest_specs.4.8.gz (http://rubygems.global.ssl.fastly.net/latest_specs.4.8.gz)
• bundler-1.11.2.gemspec.rz (http://rubygems.global.ssl.fastly.net/quick/Marshal.4.8/bundler-1.11.2.gemspec.rz)
• bundler-1.11.2.gem (http://rubygems.global.ssl.fastly.net/gems/bundler-1.11.2.gem)

I added these files on an intranet server, keeping the folder structure of the links above:

• $INTRANET_HOME

spec.4.8.gz e latest_specs.4.8.gz

• $INTRANET_HOME\quick\Marshal.4.8

bundler-1.11.2.gemspec.rz

• $INTRANET_HOME\gems

bundler-1.11.2.gem

Then I added my intranet to access gem source:

gem sources -a http://mydomain.com.br

I have run with the success the "gem install bundler" after installation, all it took was remove my intranet of the gem:

gem sources -r http://mydomain.com.br

I hope that is useful in any similar situation....

Open Windows PowerShell, and use the below command:

Get-FileHash C:\Users\Deepak\Downloads\ubuntu-20.10-desktop-amd64.iso

To those still having problems, I solved it this way:

List<Item> newItems = databaseHandler.getItems();
ListArrayAdapter.clear();
ListArrayAdapter.addAll(newItems);
ListArrayAdapter.notifyDataSetChanged();
databaseHandler.close();

I first cleared the data from the adapter, then added the new collection of items, and only then set notifyDataSetChanged(); This was not clear for me at first, so I wanted to point this out. Take note that without calling notifyDataSetChanged() the view won't be updated.

Submit is null because it is not part of activity_main.xml

When you call findViewById inside an Activity, it is going to look for a View inside your Activity's layout.

try this instead :

Submit = (Button)loginDialog.findViewById(R.id.Submit);

Another thing : you use

android:layout_below="@+id/LoginTitle"

but what you want is probably

android:layout_below="@id/LoginTitle"

See this question about the difference between @id and @+id.

In Java-8 you can use IntStream to produce a stream of numbers that you want to repeat, and then convert it to array. This approach produces an expression suitable for use in an initializer:

int[] data = IntStream.generate(() -> value).limit(size).toArray();

Above, size and value are expressions that produce the number of items that you want tot repeat and the value being repeated.

Demo.

If you include the following code at the top of your script, matplotlib will run inline when in an IPython environment (like jupyter, hydrogen atom plugin...), and it will still work if you launch the script directly via command line (matplotlib won't run inline, and the charts will open in a pop-ups as usual).

from IPython import get_ipython
ipy = get_ipython()
if ipy is not None:
    ipy.run_line_magic('matplotlib', 'inline')

I have build such kind of application using approximatively the same approach except :

• I cache the generated image on the disk and always generate two to three images in advance in a separate thread.
• I don't overlay with a UIImage but instead draw the image in the layer when zooming is 1. Those tiles will be released automatically when memory warnings are issued.

Whenever the user start zooming, I acquire the CGPDFPage and render it using the appropriate CTM. The code in - (void)drawLayer: (CALayer*)layer inContext: (CGContextRef) context is like :

CGAffineTransform currentCTM = CGContextGetCTM(context);    
if (currentCTM.a == 1.0 && baseImage) {
    //Calculate ideal scale
    CGFloat scaleForWidth = baseImage.size.width/self.bounds.size.width;
    CGFloat scaleForHeight = baseImage.size.height/self.bounds.size.height; 
    CGFloat imageScaleFactor = MAX(scaleForWidth, scaleForHeight);

    CGSize imageSize = CGSizeMake(baseImage.size.width/imageScaleFactor, baseImage.size.height/imageScaleFactor);
    CGRect imageRect = CGRectMake((self.bounds.size.width-imageSize.width)/2, (self.bounds.size.height-imageSize.height)/2, imageSize.width, imageSize.height);
    CGContextDrawImage(context, imageRect, [baseImage CGImage]);
} else {
    @synchronized(issue) { 
        CGPDFPageRef pdfPage = CGPDFDocumentGetPage(issue.pdfDoc, pageIndex+1);
        pdfToPageTransform = CGPDFPageGetDrawingTransform(pdfPage, kCGPDFMediaBox, layer.bounds, 0, true);
        CGContextConcatCTM(context, pdfToPageTransform);    
        CGContextDrawPDFPage(context, pdfPage);
    }
}

issue is the object containg the CGPDFDocumentRef. I synchronize the part where I access the pdfDoc property because I release it and recreate it when receiving memoryWarnings. It seems that the CGPDFDocumentRef object do some internal caching that I did not find how to get rid of.

You can increase the performance of excel export by following these steps:

1) When you fetch data from database, avoid casting the result set to the list of entity classes. Instead assign it directly to List

List<Object[]> resultList =session.createSQLQuery("SELECT t1.employee_name, t1.employee_id ... from t_employee t1 ").list();

instead of

List<Employee> employeeList =session.createSQLQuery("SELECT t1.employee_name, t1.employee_id ... from t_employee t1 ").list();

2) Create excel workbook object using SXSSFWorkbook instead of XSSFWorkbook and create new row using SXSSFRow when the data is not empty.

3) Use java.util.Iterator to iterate the data list.

Iterator itr = resultList.iterator();

4) Write data into excel using column++.

int rowCount = 0;
int column = 0;
while(itr.hasNext()){
 SXSSFRow row = xssfSheet.createRow(rowCount++);

 Object[] object = (Object[]) itr.next();
 //column 1     
 row.setCellValue(object[column++]); // write logic to create cell with required style in setCellValue method
 //column 2
 row.setCellValue(object[column++]);
 itr.remove();
}

5) While iterating the list, write the data into excel sheet and remove the row from list using remove method. This is to avoid holding unwanted data from the list and clear the java heap size.

itr.remove();

Just use ansible_ssh_host variable

playbook_example.yml

- hosts: host1
  tasks:
  - name: Show host's ip
    debug:
      msg: "{{ ansible_ssh_host }}"

hosts.yml

[hosts]
host1   ansible_host=1.2.3.4

Result

TASK [Show host's ip] *********************************************************************************************************************************************************************************************
ok: [host1] => {
     "msg": "1.2.3.4"
}

The solution mentioned by icyerasor and provided by Pedro at http://pedroassuncao.com/blog/2009/11/12/android-location-provider-mock/ worked very well for me. However, it does not offer support for properly starting, stopping and restarting the mock GPS provider.

I have changed his code a bit and rewritten the class to be an AsyncTask instead of a Thread. This allows us to communicate with the UI Thread, so we can restart the provider at the point where we were when we stopped it. This comes in handy when the screen orientation changes.

The code, along with a sample project for Eclipse, can be found on GitHub: https://github.com/paulhoux/Android-MockProviderGPS

All credit should go to Pedro for doing most of the hard work.

I referenced to Zsolt in level 2, I input:

:w !sudo tee % > /dev/null

and then in my situation, I still can't modify the file, so it prompted that add "!". so I input

:q! 

then it works

Both John Conde's and ryeballar's answers are correct and will work.

If you want to get too geeky:

• John's has the downside that it has to make two decisions per $digest loop (it has to decide whether to add/remove center and it has to decide whether to add/remove left), when clearly only one is needed.

• Ryeballar's relies on the ternary operator which is probably going to be removed at some point (because the view should not contain any logic). (We can't be sure it will indeed be removed and it probably won't be any time soon, but if there is a more "safe" solution, why not ?)

So, you can do the following as an alternative:

ng-class="{true:'center',false:'left'}[page.isSelected(1)]"

Here is the code that worked for me:

<script src="/SiteAssets/jquery.SPServices-2013.02a.js" type="text/javascript"></script>
<script src="/SiteAssets/jquery.js" type="text/javascript"></script>

<script type="text/javascript">
  var userid= _spPageContextInfo.userId;
  var requestUri = _spPageContextInfo.webAbsoluteUrl + "/_api/web/getuserbyid(" + userid + ")";
  var requestHeaders = { "accept" : "application/json;odata=verbose" };
  $.ajax({
    url : requestUri,
    contentType : "application/json;odata=verbose",
    headers : requestHeaders,
    success : onSuccess,
    error : onError
  });

  function onSuccess(data, request){
    var loginName = data.d.Title;
    alert(loginName);
  }

  function onError(error) {
    alert("error");
  }
</script>

Use $(this) for get the desire element.

function openAll()
{
     $("tr.b_row").each(function(){
        var a_href = $(this).find('.cpt h2 a').attr('href');
        alert ("Href is: "+a_href);
     });
}

The code by "tvanfosson" was giving me "Error executing Child Request".. I have changed the OnAuthorization like this:

public override void OnAuthorization(AuthorizationContext filterContext)
    {
        base.OnAuthorization(filterContext);

        if (!_isAuthorized)
        {
            filterContext.Result = new HttpUnauthorizedResult();
        }
        else if (filterContext.HttpContext.User.IsInRole("Administrator") || filterContext.HttpContext.User.IsInRole("User") ||  filterContext.HttpContext.User.IsInRole("Manager"))
        {
            // is authenticated and is in one of the roles 
            SetCachePolicy(filterContext);
        }
        else
        {
            filterContext.Controller.TempData.Add("RedirectReason", "You are not authorized to access this page.");
            filterContext.Result = new RedirectResult("~/Error");
        }
    }

This works well and I show the TempData on error page. Thanks to "tvanfosson" for the code snippet. I am using windows authentication and _isAuthorized is nothing but HttpContext.User.Identity.IsAuthenticated...

The ScriptIgnoreAttribute class is in the System.Web.Extensions.dll assembly (Located under Assemblies > Framework in the VS Reference Manager). You have to add a reference to that assembly in your class library project.

You can find this information at top of the MSDN page for the ScriptIgnoreAttribute class.

As per Bug https://bugs.openjdk.java.net/browse/JDK-6202721

Java will not consder -Djava.security.egd=file:/dev/urandom

It should be -Djava.security.egd=file:/dev/./urandom

Key input is a predefined event. You can catch events by attaching event_sequence(s) to event_handle(s) by using one or multiple of the existing binding methods(bind, bind_class, tag_bind, bind_all). In order to do that:

1. define an event_handle method
2. pick an event(event_sequence) that fits your case from an events list

When an event happens, all of those binding methods implicitly calls the event_handle method while passing an Event object, which includes information about specifics of the event that happened, as the argument.

In order to detect the key input, one could first catch all the '<KeyPress>' or '<KeyRelease>' events and then find out the particular key used by making use of event.keysym attribute.

Below is an example using bind to catch both '<KeyPress>' and '<KeyRelease>' events on a particular widget(root):

try:                        # In order to be able to import tkinter for
    import tkinter as tk    # either in python 2 or in python 3
except ImportError:
    import Tkinter as tk


def event_handle(event):
    # Replace the window's title with event.type: input key
    root.title("{}: {}".format(str(event.type), event.keysym))


if __name__ == '__main__':
    root = tk.Tk()
    event_sequence = '<KeyPress>'
    root.bind(event_sequence, event_handle)
    root.bind('<KeyRelease>', event_handle)
    root.mainloop()

my way is this

subjcts is

[{"id":"1","title":"GFATM"},{"id":"2","title":"Court Case"},{"id":"3","title":"Renewal\/Validity"},{"id":"4","title":"Change of Details"},{"id":"5","title":"Student Query"},{"id":"6","title":"Complains"}]

sub is a Input field or whatever you like

Displaying like this

<div ng-if="x.id === sub" ng-repeat=" x in subjcts">{{x.title}}</div>

If you are creating custom buttons, e.g. see change look of checkbox tutorial

Then simply increase the width of btn_check_label_background.9.png by adding one or two more columns of transparent pixels in the center of the image; leave the 9-patch markers as they are.

USE THIS

I have had this exact issue for almost 2 weeks, extremely frustrating but I FINALLY found this site and it was a clear walk-through of what to do.

http://blog.summitcloud.com/2010/01/multivalue-parameters-with-stored-procedures-in-ssrs-sql/

I hope this helps people because it was exactly what I was looking for

Yes, you must open php.ini and remove the semicolon to:

;extension=php_openssl.dll

If you don't have that line, check that you have the file (In my PC is on D:\xampp\php\ext) and add this to php.ini in the "Dynamic Extensions" section:

extension=php_openssl.dll

Things have changed for PHP > 7. This is what i had to do for PHP 7.2.

Step: 1: Uncomment extension=openssl

Step: 2: Uncomment extension_dir = "ext"

Step: 3: Restart xampp.

Done.

Explanation: ( From php.ini )

If you wish to have an extension loaded automatically, use the following syntax:

extension=modulename

Note : The syntax used in previous PHP versions (extension=<ext>.so and extension='php_<ext>.dll) is supported for legacy reasons and may be deprecated in a future PHP major version. So, when it is possible, please move to the new (extension=<ext>) syntax.

Special Note: Be sure to appropriately set the extension_dir directive.

What about this for a catch all...

if (string.IsNullOrEmpty(x.Trim())
{
}

This will trim all the spaces if they are there avoiding the performance penalty of IsWhiteSpace, which will enable the string to meet the "empty" condition if its not null.

I also think this is clearer and its generally good practise to trim strings anyway especially if you are putting them into a database or something.

I met such problem. Visual Studio 2008 clearly said: problem was caused by libtiff.dll. It cannot be loaded for some reasom, caused by its manifest (as a matter of fact, this dll has no manifest at all). I fixed it, when I had removed libtiff.dll from my project (but simultaneously I lost ability to open compressed TIFFs!). I recompiled aforementioned dll, but problem still remains. Interesting, that at my own machine I have no such error. Three others comps refused to load my prog. Attention!!! Here http://www.error-repair-tools.com/ppc/error.php?t=0xc0150002 one wise boy wrote, that this error was caused by problem with registry and offers repair tool. I have a solid guess, that this "repair tool" will install some malicious soft at your comp.

On Windows environment, you can execute py file on Python3 shell command line with the following syntax:

exec(open('absolute path to file_name').read())

Below explains how to execute a simple helloworld.py file from python shell command line

File Location: C:/Users/testuser/testfolder/helloworld.py

File Content: print("hello world")

We can execute this file on Python3.7 Shell as below:

>>> import os
>>> abs_path = 'C://Users/testuser/testfolder'
>>> os.chdir(abs_path)
>>> os.getcwd()
'C:\\Users\\testuser\\testfolder'

>>> exec(open("helloworld.py").read())
hello world

>>> exec(open("C:\\Users\\testuser\\testfolder\\helloworld.py").read())
hello world

>>> os.path.abspath("helloworld.py")
'C:\\Users\\testuser\\testfolder\\helloworld.py'
>>> import helloworld
hello world

At a guess, you used Code::Blocks to create a Console Application project. Such a project does not link in the GDI stuff, because console applications are generally not intended to do graphics, and TextOut is a graphics function. If you want to use the features of the GDI, you should create a Win32 Gui Project, which will be set up to link in the GDI for you.

Change the loading order of your scripts so that function1 was defined before using it in ready callback.

Plus I always found it better to define ready callback as an anonymous method then named one.

Well, my solution is sort of hack, but it works and I am using it.

1vw = 1% of viewport width

1vh = 1% of viewport height

1vmin = 1vw or 1vh, whichever is smaller

1vmax = 1vw or 1vh, whichever is larger

h1 {
  font-size: 5.9vw;
}
h2 {
  font-size: 3.0vh;
}
p {
  font-size: 2vmin;
}

For instance an application has two user called ap and auc. I am passing an extra property to each route and handling the routing based on the data i get in $routeChangeStart.

Try this:

angular.module("app").config(['$routeProvider',
function ($routeProvider) {

    $routeProvider.
            when('/ap', {
                templateUrl: 'template1.html',
                controller: 'template1',
                isAp: 'ap',
            }).
            when('/auc', {
                templateUrl: 'template2.html',
                controller: 'template2',
                isAp: 'common',
            }).
            when('/ic', {
                templateUrl: 'template3.html',
                controller: 'template3',
                isAp: 'auc',
            }).
            when('/mup', {
                templateUrl: 'template4.html',
                controller: 'template4',
                isAp: 'ap',
            }).

            when('/mnu', {
                templateUrl: 'template5.html',
                controller: 'template5',
                isAp: 'common',
            }).                               
            otherwise({
                redirectTo: '/ap',
            });
   }]);

app.js:

.run(['$rootScope', '$location', function ($rootScope, $location) {                
    $rootScope.$on("$routeChangeStart", function (event, next, current) {
        if (next.$$route.isAp != 'common') {
            if ($rootScope.userTypeGlobal == 1) {
                if (next.$$route.isAp != 'ap') {
                    $location.path("/ap");
                }
            }
            else {
                if (next.$$route.isAp != 'auc') {
                    $location.path("/auc");
                }                        
            }
        }

    });
}]);

I used the TryParse that @fjdumont mentioned but in the validating event instead.

private void Number_Validating(object sender, CancelEventArgs e) {
    int val;
    TextBox tb = sender as TextBox;
    if (!int.TryParse(tb.Text, out val)) {
        MessageBox.Show(tb.Tag +  " must be numeric.");
        tb.Undo();
        e.Cancel = true;
    }
}

I attached this to two different text boxes with in my form initializing code.

    public Form1() {
        InitializeComponent();
        textBox1.Validating+=new CancelEventHandler(Number_Validating);
        textBox2.Validating+=new CancelEventHandler(Number_Validating);
    }

I also added the tb.Undo() to back out invalid changes.

Keep in mind that a cookie is actually defined by the tuple of it's name, path, and domain. If any one of those three is different, or there is more than one cookie of the same name, but defined with paths/domains that may still be visible for the URL in question, you'll still see that cookie passed on the request. E.g. if the url is "http://foo.bar.com/baz/index.html", you'll see any cookies defined on bar.com or foo.bar.com, or with a path of "/" or "/baz".

Thus, what you have looks like it should work, as long as there's only one cookie defined in the client, with the name "SSO_COOKIE_NAME", domain "SSO_DOMAIN", and path "/". If there are any cookies with different path or domain, you'll still see the cookie sent to the client.

To debug this, go into Firefox's preferences -> Security tab, and search for all cookies with the SSO_COOKIE_NAME. Click on each to see the domain and path. I'm betting you'll find one in there that's not quite what you're expecting.

The thing on the right of <- is a formula object. It is often used to denote a statistical model, where the thing on the left of the ~ is the response and the things on the right of the ~ are the explanatory variables. So in English you'd say something like "Species depends on Sepal Length, Sepal Width, Petal Length and Petal Width".

The myFormula <- part of that line stores the formula in an object called myFormula so you can use it in other parts of your R code.

Other common uses of formula objects in R

The lattice package uses them to specify the variables to plot.
The ggplot2 package uses them to specify panels for plotting.
The dplyr package uses them for non-standard evaulation.

The examples above work fine when there is only one delimiter, but it doesn't scale well for multiple delimiters. Note that this will only work for SQL Server 2016 and above.

/*Some Sample Data*/
DECLARE @mytable TABLE ([id] VARCHAR(10), [name] VARCHAR(1000));
INSERT INTO @mytable
VALUES ('1','John/Smith'),('2','Jane/Doe'), ('3','Steve'), ('4','Bob/Johnson')


/*Split based on delimeter*/
SELECT P.id, [1] 'FirstName', [2] 'LastName', [3] 'Col3', [4] 'Col4'
FROM(
    SELECT A.id, X1.VALUE, ROW_NUMBER() OVER (PARTITION BY A.id ORDER BY A.id) RN
    FROM @mytable A
    CROSS APPLY STRING_SPLIT(A.name, '/') X1
    ) A
PIVOT (MAX(A.[VALUE]) FOR A.RN IN ([1],[2],[3],[4],[5])) P

This will do your job!

The most direct solution is this:

s = set(filelist)

The issue in your original code is that the values weren't being assigned to the set. Here's the fixed-up version of your code:

s = set()
for filename in filelist:
    s.add(filename)
print(s)

In Workbench 6.3 go to Server menu and then Choose Data Export. The dialog that comes up allows you to do all three things you want.

How do I use Python's itertools.groupby()?

You can use groupby to group things to iterate over. You give groupby an iterable, and a optional key function/callable by which to check the items as they come out of the iterable, and it returns an iterator that gives a two-tuple of the result of the key callable and the actual items in another iterable. From the help:

groupby(iterable[, keyfunc]) -> create an iterator which returns
(key, sub-iterator) grouped by each value of key(value).

Here's an example of groupby using a coroutine to group by a count, it uses a key callable (in this case, coroutine.send) to just spit out the count for however many iterations and a grouped sub-iterator of elements:

import itertools


def grouper(iterable, n):
    def coroutine(n):
        yield # queue up coroutine
        for i in itertools.count():
            for j in range(n):
                yield i
    groups = coroutine(n)
    next(groups) # queue up coroutine

    for c, objs in itertools.groupby(iterable, groups.send):
        yield c, list(objs)
    # or instead of materializing a list of objs, just:
    # return itertools.groupby(iterable, groups.send)

list(grouper(range(10), 3))

prints

[(0, [0, 1, 2]), (1, [3, 4, 5]), (2, [6, 7, 8]), (3, [9])]

The keys into the stash are actually the stash@{n} items on the left. So try:

git stash apply stash@{0}

(note that in some shells you need to quote "stash@{0}", like zsh, fish and powershell).

Since version 2.11, it's pretty easy, you can use the N stack number instead of using stash@{n}. So now instead of using:

git stash apply "stash@{n}"

You can type:

git stash apply n

To get list of stashes:

git stash list

In fact stash@{0} is a revision in git that you can switch to... but git stash apply ... should figure out how to DTRT to apply it to your current location.

My understanding is that the SQL standard calls for case-insensitivity. I don't believe any databases follow the standard completely, though.

MySQL has a configuration setting as part of its "strict mode" (a grab bag of several settings that make MySQL more standards-compliant) for case sensitive or insensitive table names. Regardless of this setting, column names are still case-insensitive, although I think it affects how the column-names are displayed. I believe this setting is instance-wide, across all databases within the RDBMS instance, although I'm researching today to confirm this (and hoping the answer is no).

I like how Oracle handles this far better. In straight SQL, identifiers like table and column names are case insensitive. However, if for some reason you really desire to get explicit casing, you can enclose the identifier in double-quotes (which are quite different in Oracle SQL from the single-quotes used to enclose string data). So:

SELECT fieldName
FROM tableName;

will query fieldname from tablename, but

SELECT "fieldName"
FROM "tableName";

will query fieldName from tableName.

I'm pretty sure you could even use this mechanism to insert spaces or other non-standard characters into an identifier.

In this situation if for some reason you found explicitly-cased table and column names desirable it was available to you, but it was still something I would highly caution against.

My convention when I used Oracle on a daily basis was that in code I would put all Oracle SQL keywords in uppercase and all identifiers in lowercase. In documentation I would put all table and column names in uppercase. It was very convenient and readable to be able to do this (although sometimes a pain to type so many capitals in code -- I'm sure I could've found an editor feature to help, here).

In my opinion MySQL is particularly bad for differing about this on different platforms. We need to be able to dump databases on Windows and load them into UNIX, and doing so is a disaster if the installer on Windows forgot to put the RDBMS into case-sensitive mode. (To be fair, part of the reason this is a disaster is our coders made the bad decision, long ago, to rely on the case-sensitivity of MySQL on UNIX.) The people who wrote the Windows MySQL installer made it really convenient and Windows-like, and it was great to move toward giving people a checkbox to say "Would you like to turn on strict mode and make MySQL more standards-compliant?" But it is very convenient for MySQL to differ so signficantly from the standard, and then make matters worse by turning around and differing from its own de facto standard on different platforms. I'm sure that on differing Linux distributions this may be further compounded, as packagers for different distros probably have at times incorporated their own preferred MySQL configuration settings.

Here's another SO question that gets into discussing if case-sensitivity is desirable in an RDBMS.

all you need to do is just add $mail->IsHTML(true); to the code it works fine..

Here's what I've been doing to cope with the situation.

I use global imports on a new test class.

import static org.junit.Assert.*;
import static org.mockito.Mockito.*;
import static org.mockito.Matchers.*;

When you are finished writing your test and need to commit, you just CTRL+SHIFT+O to organize the packages. For example, you may just be left with:

import static org.mockito.Mockito.doThrow;
import static org.mockito.Mockito.mock;
import static org.mockito.Mockito.verify;
import static org.mockito.Mockito.when;
import static org.mockito.Matchers.anyString;

This allows you to code away without getting 'stuck' trying to find the correct package to import.

def rolling_window(list, degree):
    for i in range(len(list)-degree+1):
        yield [list[i+o] for o in range(degree)]

Made this for a rolling average function

MySQL can index the first x characters of a column,but a TEXT type is of variable length so mysql cant assure the uniqueness of the column.If you still want text column,use VARCHAR.

In the accepted answer the ConcurrentBag is not required. Here's an implementation without it:

var tasks = myCollection.Select(GetData).ToList();
await Task.WhenAll(tasks);
var results = tasks.Select(t => t.Result);

Any of the "// some pre stuff" and "// some post stuff" can go into the GetData implementation (or another method that calls GetData)

Aside from being shorter, there's no use of an "async void" lambda, which is an anti pattern.

You are mixing mysqli and mysql extensions, which will not work.

You need to use

$myConnection= mysqli_connect("$db_host","$db_username","$db_pass") or die ("could not connect to mysql"); 

mysqli_select_db($myConnection, "mrmagicadam") or die ("no database");   

mysqli has many improvements over the original mysql extension, so it is recommended that you use mysqli.

What do you mean by delete? In Python, removing a reference (or a name) can be done with the del keyword, but if there are other names to the same object that object will not be deleted.

--> test = 3
--> print(test)
3
--> del test
--> print(test)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'test' is not defined

compared to:

--> test = 5
--> other is test  # check that both name refer to the exact same object
True
--> del test       # gets rid of test, but the object is still referenced by other
--> print(other)
5

Even you don't need to measure the length of string. A ! operator can solve everything for you. Remember always: !(empty string) = true !(some string) = false

So you could write:

<input ng-model="somefield">
<span ng-show="!somefield">Sorry, the field is empty!</span>
<span ng-hide="!somefield">Thanks. Successfully validated!</span>

check this if it works it works fine for me

<script>
  var windowObjectReference;
  var strWindowFeatures = "menubar=no,location=no,resizable=no,scrollbars=no,status=yes,width=400,height=350";

     function openRequestedPopup() {
      windowObjectReference = window.open("http://www.flyingedge.in/", "CNN_WindowName", strWindowFeatures);
     }
</script>

To clarify. What is important to know is that:

• Yes, you have to pass a Javascript Date object.
• Yes, it has to be ISODate friendly
• Yes, from my experience getting this to work, you need to manipulate the date to ISO
• Yes, working with dates is generally always a tedious process, and mongo is no exception

Here is a working snippet of code, where we do a little bit of date manipulation to ensure Mongo (here i am using mongoose module and want results for rows whose date attribute is less than (before) the date given as myDate param) can handle it correctly:

var inputDate = new Date(myDate.toISOString());
MyModel.find({
    'date': { $lte: inputDate }
})

The reason I used a + instead of a '*' is because a plus is defined as one or more of the preceding element, where an asterisk is zero or more. In this case we want a delimiter that's a little more concrete, so "one or more" spaces.

word[Aa]\s+word[Bb]\s+word[Cc]

will match:

wordA wordB     wordC
worda wordb wordc
wordA   wordb   wordC

The words, in this expression, will have to be specific, and also in order (a, b, then c)

I am posting an answer here, since I had the same error message for a different reason.

This error message can happen, for example, if you are using apache httpd to proxy requests from a source on protocol A to target on protocol B.

Here is the example of my situation:

AH01144: No protocol handler was valid for the URL /sockjs-node/info (scheme 'ws').

In the case above, what was happening was simply the following. I had enabled mod proxy to proxy websocket requests to nodejs based on path /sockjs-node.

The problem is that node does not use the path /sockjs-node for websocket requests exclusively. It also uses this path for hosting REST entrypoints that deliver information about websockets.

In this manner, when the application would try to open http://localhost:7001/sockjs-node/info, apache httpd would be trying to route the rest call from HTTP protocol to to a Webscoket endpoint call. Node did not accept this.

This lead to the exception above.

So be mindful that even if you enable the right modules, if you try to do the wrong forwarding, this will end with apache httpd informing you that the protocol you tried to use on the target server is not valid.

This solution worked for me. I needed to create urls for a REST client dynamically so I created this method, so you just have to pass the restURL like this

/customer/{0}/user/{1}/order

and add as many params as you need:

public String createURL (String restURL, Object ... params) {       
    return new MessageFormat(restURL).format(params);
}

You just have to call this method like this:

createURL("/customer/{0}/user/{1}/order", 123, 321);

The output

"/customer/123/user/321/order"

**403 Forbidden **

You don't have permission to access /Folder-Name/ on this server**

The solution for this problem is:

1.go to etc/apache2/apache2.conf

2.find the below code and change AllowOverride all to AllowOverride none

 <Directory /var/www/>
    Options Indexes FollowSymLinks
    AllowOverride all      Change this to--->  AllowOverride none
    Require all granted
 </Directory>

It will work fine on your Ubuntu server

To convert UTC time to Local you have to use moment.local().

For more info see docs

Example:

var date = moment.utc().format('YYYY-MM-DD HH:mm:ss');

console.log(date); // 2015-09-13 03:39:27

var stillUtc = moment.utc(date).toDate();
var local = moment(stillUtc).local().format('YYYY-MM-DD HH:mm:ss');

console.log(local); // 2015-09-13 09:39:27

Demo:

var date = moment.utc().format();_x000D_
console.log(date, "- now in UTC"); _x000D_
_x000D_
var local = moment.utc(date).local().format();_x000D_
console.log(local, "- UTC now to local");

The use case that lead me to search for this is the following

def setfrom(self,f):
    """Set from iterable f"""
    fi = iter(f)
    for i in range(self.n):
        try:
            x = next(fi)
        except StopIteration:
            fi = iter(f)
            x = next(fi)
        self.a[i] = x 

where hasnext() is available, one could do

def setfrom(self,f):
    """Set from iterable f"""
    fi = iter(f)
    for i in range(self.n):
        if not hasnext(fi):
            fi = iter(f) # restart
        self.a[i] = next(fi)

which to me is cleaner. Obviously you can work around issues by defining utility classes, but what then happens is you have a proliferation of twenty-odd different almost-equivalent workarounds each with their quirks, and if you wish to reuse code that uses different workarounds, you have to either have multiple near-equivalent in your single application, or go around picking through and rewriting code to use the same approach. The 'do it once and do it well' maxim fails badly.

Furthermore, the iterator itself needs to have an internal 'hasnext' check to run to see if it needs to raise an exception. This internal check is then hidden so that it needs to be tested by trying to get an item, catching the exception and running the handler if thrown. This is unnecessary hiding IMO.
