The /P switch allows you to set the value of a variable to a line of input entered by the user. Displays the specified promptString before reading the line of input. The promptString can be empty.

Two ways I've used it... first:

SET /P variable=

When batch file reaches this point (when left blank) it will halt and wait for user input. Input then becomes variable.

And second:

SET /P variable=<%temp%\filename.txt

Will set variable to contents (the first line) of the txt file. This method won't work unless the /P is included. Both tested on Windows 8.1 Pro, but it's the same on 7 and 10.

You could use my service: https://SmartIP.io , which provides full country names and city names of any IP address. We also expose timezones, currency, proxy detection, TOR nodes detection and Crypto detection.

You just need to signup and get a free API key which allows for 250,000 requests per month.

Using the official PHP library, the API call becomes:

$apiKey = "your API key";
$smartIp = new SmartIP($apiKey);
$response = $smartIp->requestIPData("8.8.8.8");

echo "\nstatus code: " . $response->{"status-code"};
echo "\ncountry name: " . $response->country->{"country-name"};

Show them that the base-10 system suffers from exactly the same problem.

Try to represent 1/3 as a decimal representation in base 10. You won't be able to do it exactly.

So if you write "0.3333", you will have a reasonably exact representation for many use cases.

But if you move that back to a fraction, you will get "3333/10000", which is not the same as "1/3".

Other fractions, such as 1/2 can easily be represented by a finite decimal representation in base-10: "0.5"

Now base-2 and base-10 suffer from essentially the same problem: both have some numbers that they can't represent exactly.

While base-10 has no problem representing 1/10 as "0.1" in base-2 you'd need an infinite representation starting with "0.000110011..".

The simplest ways for me are these ones:

array = [1, 2, 2, 3]

Array#to_set

array.to_set.to_a

# [1, 2, 3]

Array#uniq

array.uniq

# [1, 2, 3]

Use

cursor: pointer;
cursor: hand;

if you want to have a crossbrowser result!

I've just replied to the related question given by Vanuan (Eclipse CDT: Unresolved inclusion of stl header), and this is my answer :

You could also try use "CDT GCC Built-in Compiler Settings". Go to the project properties > C/C++ General > Preprocessor Include Path > Providers tab then check "CDT GCC Built-in Compiler Settings" if it is not.

None of the other solutions (play with include path, etc) worked for me for the type 'string', but this one fixed it.

All of them are concentrating on the for loop but if we use a normal loop then we had to use of the cursor record variable. The following is the modified code

 CREATE OR REPLACE PROCEDURE PRINT_ACTOR_QUOTES (id_actor char)
    AS
    CURSOR quote_recs IS
    SELECT a.firstName,a.lastName, m.title, m.year, r.roleName ,q.quotechar from quote q, role r,   
    rolequote rq, actor a, movie m
    where
    rq.quoteID = q.quoteID
    AND
    rq.roleID = r.roleID
     AND
    r.actorID = a.actorID
    AND
    r.movieID = m.movieID
    AND
     a.actorID = id_actor;
    recd quote_recs%rowtype;
    BEGIN
    open quote_recs;
    LOOP
    fetch quote_recs into recs;
    exit when quote_recs%notfound;
    DBMS_OUTPUT.PUT_LINE(recd.firstName||recd.lastName);
    end loop;
    close quote_recs;
    END PRINT_ACTOR_QUOTES;
    / 

If you don't know how many columns you are going to have, the declaration

table-layout: fixed

along with not setting any column widths, would imply that browsers divide the total width evenly - no matter what.

That can also be the problem with this approach, if you use this, you should also consider how overflow is to be handled.

In current version of Jekyll, it defaults to http://127.0.0.1:4000/.
This is good, if you are connected to a network but do not want anyone else to access your application.

However it may happen that you want to see how your application runs on a mobile or from some other laptop/computer.

In that case, you can use

jekyll serve --host 0.0.0.0

This binds your application to the host & next use following to connect to it from some other host

http://host's IP adress/4000 

Something like this

 string find = "item_manuf_id = 'some value'";
 DataRow[] foundRows = table.Select(find);

Solution native Javascript :

document.getElementById("theSelectId").insertBefore(new Option('', ''), document.getElementById("theSelectId").firstChild);

example : http://codepen.io/anon/pen/GprybL

I'd say export your server config in IIS manager:

1. In IIS manager, click the Server node
2. Go to Shared Configuration under "Management"
3. Click “Export Configuration”. (You can use a password if you are sending them across the internet, if you are just gonna move them via a USB key then don't sweat it.)

4. Move these files to your new server

   administration.config
   applicationHost.config
   configEncKey.key 
   

5. On the new server, go back to the “Shared Configuration” section and check “Enable shared configuration.” Enter the location in physical path to these files and apply them.

6. It should prompt for the encryption password(if you set it) and reset IIS.

BAM! Go have a beer!

This is based on the assumption that you're getting an error about the date format, such as an invalid month value or non-numeric character when numeric expected.

Dates stored in the database do not have formats. When you query the date your client is formatting the date for display, as 4/16/2011. Normally the same date format is used for selecting and updating dates, but in this case they appear to be different - so your client is apparently doing something more complicated that SQL*Plus, for example.

When you try to update it it's using a default date format model. Because of how it's displayed you're assuming that is MM/DD/YYYY, but it seems not to be. You could find out what it is, but it's better not to rely on the default or any implicit format models at all.

Whether that is the problem or not, you should always specify the date model:

UPDATE PASOFDATE SET ASOFDATE = TO_DATE('11/21/2012', 'MM/DD/YYYY');

Since you aren't specifying a time component - all Oracle DATE columns include a time, even if it's midnight - you could also use a date literal:

UPDATE PASOFDATE SET ASOFDATE = DATE '2012-11-21';

You should maybe check that the current value doesn't include a time, though the column name suggests it doesn't.

1. The legend is part of the default options of the ChartJs library. So you do not need to explicitly add it as an option.

2. The library generates the HTML. It is merely a matter of adding that to the your page. For example, add it to the innerHTML of a given DIV. (Edit the default options if you are editing the colors, etc)

<div>
    <canvas id="chartDiv" height="400" width="600"></canvas>
    <div id="legendDiv"></div>

tl;dr What to do in modern (2018) times? Assume tel: is supported, use it and forget about anything else.

The tel: URI scheme RFC5431 (as well as sms: but also feed:, maps:, youtube: and others) is handled by protocol handlers (as mailto: and http: are).

They're unrelated to HTML5 specification (it has been out there from 90s and documented first time back in 2k with RFC2806) then you can't check for their support using tools as modernizr. A protocol handler may be installed by an application (for example Skype installs a callto: protocol handler with same meaning and behaviour of tel: but it's not a standard), natively supported by browser or installed (with some limitations) by website itself.

What HTML5 added is support for installing custom web based protocol handlers (with registerProtocolHandler() and related functions) simplifying also the check for their support through isProtocolHandlerRegistered() function.

There is some easy ways to determine if there is an handler or not:" How to detect browser's protocol handlers?).

In general what I suggest is:

1. If you're running on a mobile device then you can safely assume tel: is supported (yes, it's not true for very old devices but IMO you can ignore them).
2. If JS isn't active then do nothing.
3. If you're running on desktop browsers then you can use one of the techniques in the linked post to determine if it's supported.
4. If tel: isn't supported then change links to use callto: and repeat check desctibed in 3.
5. If tel: and callto: aren't supported (or - in a desktop browser - you can't detect their support) then simply remove that link replacing URL in href with javascript:void(0) and (if number isn't repeated in text span) putting, telephone number in title. Here HTML5 microdata won't help users (just search engines). Note that newer versions of Skype handle both callto: and tel:.

Please note that (at least on latest Windows versions) there is always a - fake - registered protocol handler called App Picker (that annoying window that let you choose with which application you want to open an unknown file). This may vanish your tests so if you don't want to handle Windows environment as a special case you can simplify this process as:

1. If you're running on a mobile device then assume tel: is supported.
2. If you're running on desktop then replace tel: with callto:. then drop tel: or leave it as is (assuming there are good chances Skype is installed).

Pseudo code from Wikipedia translated into the most compact Java

(year % 400 == 0) || ((year % 4 == 0) && (year % 100 != 0))

this will provide exact output

import csv

import collections

with open('file.csv', 'rb') as f:

  data = list(csv.reader(f))

counter = collections.defaultdict(int)

for row in data:

    counter[row[0]] += 1

writer = csv.writer(open("file1.csv", 'w'))

for row in data:

    if counter[row[0]] >= 1:

        writer.writerow(row)

I suggest the following change

let propertyName =  {} as any;

Here's a potential solution that will set the width of the bookType column (i.e. format of the bookTypes value) based on the longest bookTypes value.

public class Test {
    public static void main(String[] args) {
        String[] bookTypes = { "Newspaper", "Paper Back", "Hardcover book", "Electronic book", "Magazine" };
        double[] costs = { 1.0, 7.5, 10.0, 2.0, 3.0 };

        // Find length of longest bookTypes value.
        int maxLengthItem = 0;
        boolean firstValue = true;
        for (String bookType : bookTypes) {
            maxLengthItem = (firstValue) ? bookType.length() : Math.max(maxLengthItem, bookType.length());
            firstValue = false;
        }

        // Display rows of data
        for (int i = 0; i < bookTypes.length; i++) {
            // Use %6.2 instead of %.2 so that decimals line up, assuming max
            // book cost of $999.99. Change 6 to a different number if max cost
            // is different
            String format = "%d. %-" + Integer.toString(maxLengthItem) + "s \t\t $%9.2f\n";
            System.out.printf(format, i + 1, bookTypes[i], costs[i]);
        }
    }
}

Valid timeZone values are based on the tz (timezone) database used by Linux and other Unix systems. The values are strings (xsd:string) in the form “Area/Location,” in which:

Area is a continent or ocean name. Area currently includes:

• Africa
• America (both North America and South America)
• Antarctica
• Arctic
• Asia
• Atlantic
• Australia
• Europe
• Etc (administrative zone. For example, “Etc/UTC” represents Coordinated Universal Time.)
• Indian
• Pacific

Location is the city, island, or other regional name.

The zone names and output abbreviations adhere to POSIX (portable operating system interface) UNIX conventions, which uses positive (+) signs west of Greenwich and negative (-) signs east of Greenwich, which is the opposite of what is generally expected. For example, “Etc/GMT+4” corresponds to 4 hours behind UTC (that is, west of Greenwich) rather than 4 hours ahead of UTC (Coordinated Universal Time) (east of Greenwich).

Here is a list all valid timezones

You can change time zone in your settings.py as follows

LANGUAGE_CODE = 'en-us'

TIME_ZONE = 'Asia/Kolkata'

USE_I18N = True

USE_L10N = True

USE_TZ = True

In Scripting languages like (JavaScript and old PHP versions) we use existing fundamental functions and method for performing our job. Lets take an example in JavaScript we can use ajax or web-sockets only if they are supported by browser or methods exist or them in browser. But in languages like C or C++ , Java we can write that feature from scratch even if any library for that feature is not available but we can't do so in JavaScript.

can you support web-sockets in Internet Explorer 8 or prior with the help of JavaScript But you can write a plugin in C or C++ or Java which may add a feature of web-socket to Internet Explorer 8.

Basically in Scripting languages we write a code in a sequence which execute existing methods in a sequence to complete our job. Entering numbers and formula in a digital calculator to do a operation is also a very example of scripting language.We should note that the compiler/run-time-environment of every scripting language is always written in programming language in which we can add more features and methods and can write new libraries.

PHP This is language which is somewhat b/w programming and scripting. We can add new methods by adding compiled extensions written in another High Level Language. We can't add high level features of networking or creating image processing libraries directly in PHP.

P.S. I am really sorry for revolving my answer around PHP JavaScript only but I use these two because I have a considerable experience in these two.

If you want to use numpy only:

x = [-1, 2, 1, 3, 3]
vals,counts = np.unique(x, return_counts=True)

gives

(array([-1,  1,  2,  3]), array([1, 1, 1, 2]))

And extract it:

index = np.argmax(counts)
return vals[index]

Use [ngClass] and conditionally apply class based on the id.

In your HTML file:

<li>
    <img [ngClass]="{'this-is-a-class': id === 1 }" id="1"  
         src="../../assets/images/1.jpg" (click)="addClass(id=1)"/>
</li>
<li>
    <img [ngClass]="{'this-is-a-class': id === 2 }" id="2"  
         src="../../assets/images/2.png" (click)="addClass(id=2)"/>
</li>

In your TypeScript file:

addClass(id: any) {
    this.id = id;
}

Following query can be used to get all privileges of one user .. Just provide user name in first query and you will get all privileges to that

I came across this question, and the answers here didn't work for me; i couldn't figure out why i can't login and got the above error.

It turns out that postgresql saves usernames lowercase, but during authentication it uses both upper- and lowercase.

CREATE USER myNewUser WITH PASSWORD 'passWord';

will create a user with the username 'mynewuser' and password 'passWord'.

This means you have to authenticate with 'mynewuser', and not with 'myNewUser'. For a newbie in pgsql like me, this was confusing. I hope it helps others who run into this problem.

str.strip() returns a string with leading+trailing whitespace removed, .lstrip and .rstrip for only leading and trailing respectively.

grades.append(lists[i].rstrip('\n').split(','))

If your context is an activity you can call overridePendingTransition:

Call immediately after one of the flavors of startActivity(Intent) or finish to specify an explicit transition animation to perform next.

So, programmatically:

this.startActivity(new Intent(v.getContext(), newactivity.class));
this.overridePendingTransition(0, 0);

From the article:

XPathDocument myXPathDoc = new XPathDocument(myXmlFile) ;
XslTransform myXslTrans = new XslTransform() ;
myXslTrans.Load(myStyleSheet);
XmlTextWriter myWriter = new XmlTextWriter("result.html",null) ;
myXslTrans.Transform(myXPathDoc,null,myWriter) ;

Edit:

But my trusty compiler says, XslTransform is obsolete: Use XslCompiledTransform instead:

XPathDocument myXPathDoc = new XPathDocument(myXmlFile) ;
XslCompiledTransform myXslTrans = new XslCompiledTransform();
myXslTrans.Load(myStyleSheet);
XmlTextWriter myWriter = new XmlTextWriter("result.html",null);
myXslTrans.Transform(myXPathDoc,null,myWriter);

function makeEditable(elem){
    elem.setAttribute('contenteditable', 'true');
    elem.addEventListener('blur', function (evt) {
        elem.removeAttribute('contenteditable');
        elem.removeEventListener('blur', evt.target);
    });
    elem.focus();
}

To use it, call on (say) a header element with id="myHeader"

makeEditable(document.getElementById('myHeader'))

That element will now be editable by the user until it loses focus.

using :<line number> you can navigate to any line, thus :1 takes you to the first line.

When you want to treat lambda expressions as expression trees and look inside them instead of executing them. For example, LINQ to SQL gets the expression and converts it to the equivalent SQL statement and submits it to server (rather than executing the lambda).

Conceptually, Expression<Func<T>> is completely different from Func<T>. Func<T> denotes a delegate which is pretty much a pointer to a method and Expression<Func<T>> denotes a tree data structure for a lambda expression. This tree structure describes what a lambda expression does rather than doing the actual thing. It basically holds data about the composition of expressions, variables, method calls, ... (for example it holds information such as this lambda is some constant + some parameter). You can use this description to convert it to an actual method (with Expression.Compile) or do other stuff (like the LINQ to SQL example) with it. The act of treating lambdas as anonymous methods and expression trees is purely a compile time thing.

Func<int> myFunc = () => 10; // similar to: int myAnonMethod() { return 10; }

will effectively compile to an IL method that gets nothing and returns 10.

Expression<Func<int>> myExpression = () => 10;

will be converted to a data structure that describes an expression that gets no parameters and returns the value 10:

larger image

While they both look the same at compile time, what the compiler generates is totally different.

Given the following sample

myData <- data.frame(A=rep(1:2, 3), B=rep(1:3, 2), Pulse=20:25)  

then

myData$A <-as.factor(myData$A)
myData$B <-as.factor(myData$B)

or you could select your columns altogether and wrap it up nicely:

# select columns
cols <- c("A", "B")
myData[,cols] <- data.frame(apply(myData[cols], 2, as.factor))

levels(myData$A) <- c("long", "short")
levels(myData$B) <- c("1kg", "2kg", "3kg")

To obtain

> myData
      A   B Pulse
1  long 1kg    20
2 short 2kg    21
3  long 3kg    22
4 short 1kg    23
5  long 2kg    24
6 short 3kg    25

There is one way to implement multiple interface.

Just extend one interface from another or create interface that extends predefined interface Ex:

public interface PlnRow_CallBack extends OnDateSetListener {
    public void Plan_Removed();
    public BaseDB getDB();
}

now we have interface that extends another interface to use in out class just use this new interface who implements two or more interfaces

public class Calculator extends FragmentActivity implements PlnRow_CallBack {

    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {

    }

    @Override
    public void Plan_Removed() {

    }

    @Override
    public BaseDB getDB() {

    }
}

hope this helps

pipdeptree is a command line utility for displaying the python packages installed in an virtualenv in form of a dependency tree. Just use it: https://github.com/naiquevin/pipdeptree

psql --pset=format=FORMAT

Great for executing queries from command line, e.g.

psql --pset=format=unaligned -c "select bandanavalue from bandana where bandanakey = 'atlassian.confluence.settings';"

Another example, more simple than some others with simple return of incremented value:

function testIncrement1(x) {
    return x++;
}

function testIncrement2(x) {
    return ++x;
}

function testIncrement3(x) {
    return x += 1;
}

console.log(testIncrement1(0)); // 0
console.log(testIncrement2(0)); // 1
console.log(testIncrement3(0)); // 1

As you can see, no post-increment/decrement should be used at return statement, if you want this operator to influence the result. But return doesn't "catch" post-increment/decrement operators:

function closureIncrementTest() {
    var x = 0;

    function postIncrementX() {
        return x++;
    }

    var y = postIncrementX();

    console.log(x); // 1
}

There are just two minor things here.

The first is in the following carousel indicator list items:

<li data-target="carousel" data-slide-to="0"></li>

You need to pass the data-target attribute a selector which means the ID must be prefixed with #. So change them to the following:

<li data-target="#carousel" data-slide-to="0"></li>

Secondly, you need to give the carousel a starting point so both the carousel indicator items and the carousel inner items must have one active class. Like this:

<ol class="carousel-indicators">
    <li data-target="#carousel" data-slide-to="0" class="active"></li>
    <!-- Other Items -->
</ol>
<div class="carousel-inner">
    <div class="item active">
        <img src="https://picsum.photos/1500/600?image=1" alt="Slide 1" />
    </div>
    <!-- Other Items -->
</div>

Well you are trying to compare Date with Nvarchar which is wrong. Should be

Where dates between date1 And date2
-- both date1 & date2 should be date/datetime

If date1,date2 strings; server will convert them to date type before filtering.

did you try this ?

$("#yourdiv").load(url, function(){ 

         your functions goes here !!!

}); 

If all you want is XSD, LiquidXML has a free version that does XSDs, and its got a GUI to it so you can tweak the XSD if you like. Anyways nowadays I write my own XSDs by hand, but its all thanks to this app.

A minor update to this: a sender should never set the Return-Path: header. There's no such thing as a Return-Path: header for a message in transit. That header is set by the MTA that makes final delivery, and is generally set to the value of the 5321.From unless the local system needs some kind of quirky routing.

It's a common misunderstanding because users rarely see an email without a Return-Path: header in their mailboxes. This is because they always see delivered messages, but an MTA should never see a Return-Path: header on a message in transit. See http://tools.ietf.org/html/rfc5321#section-4.4

string.containsString is only available in 10.10 Yosemite (and probably iOS8). Also bridging it to ObjectiveC crashes in 10.9. You're trying to pass a NSString to NSCFString. I don't know the difference, but I can say 10.9 barfs when it executes this code in a OS X 10.9 app.

Here are the differences in Swift with 10.9 and 10.10: https://developer.apple.com/library/prerelease/mac/documentation/General/Reference/APIDiffsMacOSX10_10SeedDiff/index.html containsString is only available in 10.10

Range of String above works great on 10.9. I am finding developing on 10.9 is super stable with Xcode beta2. I don't use playgrounds through or the command line version of playgrounds. I'm finding if the proper frameworks are imported the autocomplete is very helpful.

Here you go, just tweaked readsquare's answer to return an array of all classes:

function classList(elem){
   var classList = elem.attr('class').split(/\s+/);
    var classes = new Array(classList.length);
    $.each( classList, function(index, item){
        classes[index] = item;
    });

    return classes;
}

Pass a jQuery element to the function, so that a sample call will be:

var myClasses = classList($('#myElement'));

Here you can Find some other way to do the same.

Read file.

File file1 = new File("C:\Build\myfolder\myTestfile.txt");
def String yourData = file1.readLines();

Read Full file.

File file1 = new File("C:\Build\myfolder\myfile.txt");
def String yourData= file1.getText();

Read file Line Bye Line.

File file1 = new File("C:\Build\myfolder\myTestfile.txt");
for (def i=0;i<=30;i++) // specify how many line need to read eg.. 30
{
 log.info file1.readLines().get(i)

}

Create a new file.

new File("C:\Temp\FileName.txt").createNewFile();

How to change commits deeper in history

Since history in Git is immutable, fixing anything but the most recent commit (commit which is not branch head) requires that the history is rewritten from the changed commit and forward.

You can use StGIT for that, initialize branch if necessary, uncommitting up to the commit you want to change, pop to it if necessary, make a change then refresh patch (with -e option if you want to correct commit message), then push everything and stg commit.

Or you can use rebase to do that. Create new temporary branch, rewind it to the commit you want to change using git reset --hard, change that commit (it would be top of current head), then rebase branch on top of changed commit, using git rebase --onto .

Or you can use git rebase --interactive, which allows various modifications like patch re-ordering, collapsing, ...

I think that should answer your question. However, note that if you have pushed code to a remote repository and people have pulled from it, then this is going to mess up their code histories, as well as the work they've done. So do it carefully.

The git checkout master of the answer by Woland isn't needed. Instead use the "Checkout to specific local branch" in the "Additional Behaviors" section to set the "Branch name" to master.

The git commit -am "blah" is still needed.

Now you can use the "Git Publisher" under "Post-build Actions" to push the changes. Be sure to specify the "Branches" to push ("Branch to push" = master, "Target remote name" = origin).

"Merge Results" isn't needed.

You can use the expression pipeline to achieve this:

 public static Func<object, object> Caster(Type type)
 {
    var inputObject = Expression.Parameter(typeof(object));
    return Expression.Lambda<Func<object,object>>(Expression.Convert(inputObject, type), inputPara).Compile();
 }

which you can invoke like:

object objAsDesiredType = Caster(desiredType)(obj);

Drawbacks: The compilation of this lambda is slower than nearly all other methods mentioned already

Advantages: You can cache the lambda, then this should be actually the fastest method, it is identical to handwritten code at compile time

I suppose you could use a solution such as this one :

select name, length(name)
from users
where id = (
    select id
    from users
    order by length(name) desc
    limit 1
);

Might not be the optimal solution, though... But seems to work.

You can make a method just like new Date(year,month,date) in your code by using Calendar class.

private Date getDate(int year,int month,int date){
    Calendar cal = Calendar.getInstance();
    cal.set(Calendar.YEAR, year);
    cal.set(Calendar.MONTH, month-1);
    cal.set(Calendar.DAY_OF_MONTH, day);
    return cal.getTime();
}

It will work just like the deprecated constructor of Date

Use is_same:

#include <type_traits>

template <typename T>
void foo()
{
    if (std::is_same<T, animal>::value) { /* ... */ }  // optimizable...
}

Usually, that's a totally unworkable design, though, and you really want to specialize:

template <typename T> void foo() { /* generic implementation  */ }

template <> void foo<animal>()   { /* specific for T = animal */ }

Note also that it's unusual to have function templates with explicit (non-deduced) arguments. It's not unheard of, but often there are better approaches.

Here is just another option you couold apply for ASP NET MVC.

Normally you shoud use BaseController class for each Controller class.

So inside of it's constructor method do following.

public class BaseController : Controller
{
        public BaseController()
        {
            // get the previous url and store it with view model
            ViewBag.PreviousUrl = System.Web.HttpContext.Current.Request.UrlReferrer;
        }
}

And now in ANY view you can do like

<button class="btn btn-success mr-auto" onclick="  window.location.href = '@ViewBag.PreviousUrl'; " style="width:2.5em;"><i class="fa fa-angle-left"></i></button>

Enjoy!

This is what worked for me. Issue is earlier I didn't set Content Type(header) when I used exchange method.

MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
map.add("param1", "123");
map.add("param2", "456");
map.add("param3", "789");
map.add("param4", "123");
map.add("param5", "456");

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

final HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<MultiValueMap<String, String>>(map ,
        headers);
JSONObject jsonObject = null;

try {
    RestTemplate restTemplate = new RestTemplate();
    ResponseEntity<String> responseEntity = restTemplate.exchange(
            "https://url", HttpMethod.POST, entity,
            String.class);

    if (responseEntity.getStatusCode() == HttpStatus.CREATED) {
        try {
            jsonObject = new JSONObject(responseEntity.getBody());
        } catch (JSONException e) {
            throw new RuntimeException("JSONException occurred");
        }
    }
  } catch (final HttpClientErrorException httpClientErrorException) {
        throw new ExternalCallBadRequestException();
  } catch (HttpServerErrorException httpServerErrorException) {
        throw new ExternalCallServerErrorException(httpServerErrorException);
  } catch (Exception exception) {
        throw new ExternalCallServerErrorException(exception);
    } 

ExternalCallBadRequestException and ExternalCallServerErrorException are the custom exceptions here.

Note: Remember HttpClientErrorException is thrown when a 4xx error is received. So if the request you send is wrong either setting header or sending wrong data, you could receive this exception.

How about asking the UIApplication singleton for its keyWindow, and from that UIWindow ask for the root view controller (its rootViewController property):

UIViewController root = [[[UIApplication sharedApplication] keyWindow] rootViewController];

You are getting the error because range() only takes int values as parameters.

Try using int() to convert your inputs.

As per Android official Blogs : https://android-developers.googleblog.com/2011/06/things-that-cannot-change.html

We can say that:

• If the manifest package name has changed, the new application will be installed alongside the old application, so they both co-exist on the user’s device at the same time.

• If the signing certificate changes, trying to install the new application on to the device will fail until the old version is uninstalled.

As per Google App Update check list : https://support.google.com/googleplay/android-developer/answer/113476?hl=en

Update your apps

Prepare your APK

When you're ready to make changes to your APK, make sure to update your app’s version code as well so that existing users will receive your update.

Use the following checklist to make sure your new APK is ready to update your existing users:

• The package name of the updated APK needs to be the same as the current version.
• The version code needs to be greater than that current version. Learn more about versioning your applications.
• The updated APK needs to be signed with the same signature as the current version.

To verify that your APK is using the same certification as the previous version, you can run the following command on both APKs and compare the results:

$ jarsigner -verify -verbose -certs my_application.apk

If the results are identical, you’re using the same key and are ready to continue. If the results are different, you will need to re-sign the APK with the correct key.

Learn more about signing your applications

Upload your APK Once your APK is ready, you can create a new release.

I found a solution by myself after doing some research:

• Go to Eclipse home folder.
• Search for 'android' => In Windows 7 you can use search bar.
• Delete all the file related to android, which is shown in the results.
• Restart Eclipse.
• Install the ADT plugin again and Restart plugin.

Now everything works fine.

Instead of using a submit button, try using a <button type="button">Submit</button>

You can then call a javascript function in the button, and after the alert popup is confirmed, you can manually submit the form with document.getElementById("form").submit(); ... so you'll need to name and id your form for that to work.

There is no functions in c#. There is methods (typical method:public void UpdateLeaveStatus(EmployeeLeave objUpdateLeaveStatus)) link to msdn and functors - variable of type Func<>

SET @sql = 
CONCAT( 'INSERT INTO <table_name> (', 
    (
        SELECT GROUP_CONCAT( CONCAT('`',COLUMN_NAME,'`') ) 
            FROM information_schema.columns 
            WHERE table_schema = <database_name>
                AND table_name = <table_name>
                AND column_name NOT IN ('id')
    ), ') SELECT ', 
    ( 
        SELECT GROUP_CONCAT(CONCAT('`',COLUMN_NAME,'`')) 
        FROM information_schema.columns 
        WHERE table_schema = <database_name>
            AND table_name = <table_source_name>
            AND column_name NOT IN ('id')  
    ),' from <table_source_name> WHERE <testcolumn> = <testvalue>' );  

PREPARE stmt1 FROM @sql;

Of course replace <> values with real values, and watch your quotes.

Maybe the method document.createElement(); is what you're looking for.

Line numbers are OK if you can guarantee the position of what you want. Over the years, my favorite flavor of this has been something like this:

sed "/First Line of Text/,/Last Line of Text/d" filename

which deletes all lines from the first matched line to the last match, including those lines.

Use sed -n with "p" instead of "d" to print those lines instead. Way more useful for me, as I usually don't know where those lines are.

I've been frustrated by this problem as well. Find/Replace can be helpful though, because if you don't put anything in the "replace" field it will replace with an -actual- NULL. So the steps would be something along the lines of:

1: Place some unique string in your formula in place of the NULL output (i like to use a password-like string)

2: Run your formula

3: Open Find/Replace, and fill in the unique string as the search value. Leave "replace with" blank

4: Replace All

Obviously, this has limitations. It only works when the context allows you to do a find/replace, so for more dynamic formulas this won't help much. But, I figured I'd put it up here anyway.

Check out the aq branch, and rebase from master.

git checkout aq
git rebase master

SimpleDateFormat simpleDateFormatArrivals = new SimpleDateFormat("hh:mm", Locale.UK);

for 24-hours format:

SimpleDateFormat simpleDateFormatArrivals = new SimpleDateFormat("HH:mm", Locale.UK);

Rather than browse the ouput of the :ls command and delete (unload, wipe..) a buffer by specifying its number, I find that using file names is often more effective.

For instance, after I opened a couple of .txt file to refresh my memories of some fine point.. copy and paste a few lines of text to use as a template of sorts.. etc. I would type the following:

:bd txt <Tab>

Note that the matching string does not have to be at the start of the file name.

The above displays the list of file names that match 'txt' at the bottom of the screen and keeps the :bd command I initially typed untouched, ready to be completed.

Here's an example:

doc1.txt doc2.txt
:bd txt 

I could backspace over the 'txt' bit and type in the file name I wish to delete, but where this becomes really convenient is that I don't have to: if I hit the Tab key a second time, Vim automatically completes my command with the first match:

:bd doc1.txt

If I want to get rid of this particular buffer I just need to hit Enter.

And if the buffer I want to delete happens to be the second (third.. etc.) match, I only need to keep hitting the Tab key to make my :bd command cycle through the list of matches.

Naturally, this method can also be used to switch to a given buffer via such commands as :b.. :sb.. etc.

This approach is particularly useful when the 'hidden' Vim option is set, because the buffer list can quickly become quite large, covering several screens, and making it difficult to spot the particular buffer I am looking for.

To make the most of this feature, it's probably best to read the following Vim help file and tweak the behavior of Tab command-line completion accordingly so that it best suits your workflow:

:help wildmode

The behavior I described above results from the following setting, which I chose for consistency's sake in order to emulate bash completion:

:set wildmode=list:longest,full

As opposed to using buffer numbers, the merit of this approach is that I usually remember at least part of a given file name letting me target the buffer directly rather than having to first look up its number via the :ls command.

An alternative to theme_classic() is the theme that comes with the cowplot package, theme_cowplot() (loaded automatically with the package). It looks similar to theme_classic(), with a few subtle differences. Most importantly, the default label sizes are larger, so the resulting figures can be used in publications without further modifications needed (in particular if you save them with save_plot() instead of ggsave()). Also, the background is transparent, not white, which may be useful if you want to edit the figure in illustrator. Finally, faceted plots look better, in my opinion.

Example:

library(cowplot)
a <- seq(1,20)
b <- a^0.25
df <- as.data.frame(cbind(a,b))

p <- ggplot(df, aes(x = a, y = b)) + geom_point()
save_plot('plot.png', p) # alternative to ggsave, with default settings that work well with the theme

This is what the file plot.png produced by this code looks like:

        DWORD bufCharCount = 150;
        memset(Name, 0, 150);
        if( GetComputerName( infoBuf, &bufCharCount ) )
        {
            for(i=0; i<150; i++)
            {
                Name[i] = infoBuf[i];
            }

            strcpy(Name, "Unknown_Host_Name");
        }

Here is the function for to check is String is Integer or not ?

public static boolean isStringInteger(String number ){

    }
    return true;
}

git checkout has the --ours option to check out the version of the file that you had locally (as opposed to --theirs, which is the version that you pulled in). You can pass . to git checkout to tell it to check out everything in the tree. Then you need to mark the conflicts as resolved, which you can do with git add, and commit your work once done:

git checkout --ours .  # checkout our local version of all files
git add -u             # mark all conflicted files as merged
git commit             # commit the merge

Note the . in the git checkout command. That's very important, and easy to miss. git checkout has two modes; one in which it switches branches, and one in which it checks files out of the index into the working copy (sometimes pulling them into the index from another revision first). The way it distinguishes is by whether you've passed a filename in; if you haven't passed in a filename, it tries switching branches (though if you don't pass in a branch either, it will just try checking out the current branch again), but it refuses to do so if there are modified files that that would effect. So, if you want a behavior that will overwrite existing files, you need to pass in . or a filename in order to get the second behavior from git checkout.

It's also a good habit to have, when passing in a filename, to offset it with --, such as git checkout --ours -- <filename>. If you don't do this, and the filename happens to match the name of a branch or tag, Git will think that you want to check that revision out, instead of checking that filename out, and so use the first form of the checkout command.

I'll expand a bit on how conflicts and merging work in Git. When you merge in someone else's code (which also happens during a pull; a pull is essentially a fetch followed by a merge), there are few possible situations.

The simplest is that you're on the same revision. In this case, you're "already up to date", and nothing happens.

Another possibility is that their revision is simply a descendent of yours, in which case you will by default have a "fast-forward merge", in which your HEAD is just updated to their commit, with no merging happening (this can be disabled if you really want to record a merge, using --no-ff).

Then you get into the situations in which you actually need to merge two revisions. In this case, there are two possible outcomes. One is that the merge happens cleanly; all of the changes are in different files, or are in the same files but far enough apart that both sets of changes can be applied without problems. By default, when a clean merge happens, it is automatically committed, though you can disable this with --no-commit if you need to edit it beforehand (for instance, if you rename function foo to bar, and someone else adds new code that calls foo, it will merge cleanly, but produce a broken tree, so you may want to clean that up as part of the merge commit in order to avoid having any broken commits).

The final possibility is that there's a real merge, and there are conflicts. In this case, Git will do as much of the merge as it can, and produce files with conflict markers (<<<<<<<, =======, and >>>>>>>) in your working copy. In the index (also known as the "staging area"; the place where files are stored by git add before committing them), you will have 3 versions of each file with conflicts; there is the original version of the file from the ancestor of the two branches you are merging, the version from HEAD (your side of the merge), and the version from the remote branch.

In order to resolve the conflict, you can either edit the file that is in your working copy, removing the conflict markers and fixing the code up so that it works. Or, you can check out the version from one or the other sides of the merge, using git checkout --ours or git checkout --theirs. Once you have put the file into the state you want it, you indicate that you are done merging the file and it is ready to commit using git add, and then you can commit the merge with git commit.

Actually there are 3 places where gradle.properties can be placed:

1. Under gradle user home directory defined by the GRADLE_USER_HOME environment variable, which if not set defaults to USER_HOME/.gradle
2. The sub-project directory (myProject2 in your case)
3. The root project directory (under myProject)

Gradle looks for gradle.properties in all these places while giving precedence to properties definition based on the order above. So for example, for a property defined in gradle user home directory (#1) and the sub-project (#2) its value will be taken from gradle user home directory (#1).

You can find more details about it in gradle documentation here.

NAs also appear if there are attributes with zero variance (with all elements equal); see for instance:

cor(cbind(a=runif(10),b=rep(1,10)))

which returns:

   a  b
a  1 NA
b NA  1
Warning message:
In cor(cbind(a = runif(10), b = rep(1, 10))) :
  the standard deviation is zero

See TimeSpan.TotalMinutes:

Gets the value of the current TimeSpan structure expressed in whole and fractional minutes.

You can use new Date().getTime() for getting timestamps. Then you can calculate the difference between end and start and finally transform the timestamp which is ms into s.

const start = new Date().getTime();
const end = new Date().getTime();

const diff = end - start;
const seconds = Math.floor(diff / 1000 % 60);

I believe there's a simple historical reason why you can't enumerate over methods of built-in objects like Array for instance. Here's why:

Methods are properties of the prototype-object, say Object.prototype. That means that all Object-instances will inherit those methods. That's why you can use those methods on any object. Say .toString() for instance.

So IF methods were enumerable, and I would iterate over say {a:123} with: "for (key in {a:123}) {...}" what would happen? How many times would that loop be executed?

It would be iterated once for the single key 'a' in our example. BUT ALSO once for every enumerable property of Object.prototype. So if methods were enumerable (by default), then any loop over any object would loop over all its inherited methods as well.

This web.config setup works to remove all unnecessary headers from the ASP.NET response (at least starting from IIS 10):

<system.web>
    <!-- Removes version headers from response -->
    <httpRuntime enableVersionHeader="false" />
</system.web>

<system.webServer>
    <httpProtocol>
        <customHeaders>
            <!--Removes X-Powered-By header from response -->
            <clear />
        </customHeaders>
    </httpProtocol>

    <security>
        <!--Removes Server header from response-->
        <requestFiltering removeServerHeader ="true" />
    </security>
</system.webServer>

Please note that this hides all the headers for the "application", as do all the other approaches. If you e.g. reach some default page or an error page generated by the IIS itself or ASP.NET outside your application these rules won't apply. So ideally they should be on the root level in IIS and that sill may leave some error responses to the IIS itself.

P.S. There is a bug in IIS 10 that makes it sometimes show the server header even with correct config. It should be fixed by now, but IIS/Windows has to be updated.

taking @rijul's answer forward, it doesn't work in marshmallow and above versions:

Just as a addition. You can find the Catalina Paths in

In the VM Arguments the Paths are listed and changeable

You should never look to override certificate validation in code! If you need to do testing, use an internal/test CA and install the CA root certificate on the device or emulator. You can use BurpSuite or Charles Proxy if you don't know how to setup a CA.

There is already an ISO standard for this; no need to invent your own scheme:

http://en.wikipedia.org/wiki/ISO_5218

Per the standard, the column should be called "Sex" and the 'closest' data type would be tinyint with a CHECK constraint or lookup table as appropriate.

You can do the same for method parameters as well:

Method method = someClass.getDeclaredMethod("someMethod");
Type[] types = method.getGenericParameterTypes();
//Now assuming that the first parameter to the method is of type List<Integer>
ParameterizedType pType = (ParameterizedType) types[0];
Class<?> clazz = (Class<?>) pType.getActualTypeArguments()[0];
System.out.println(clazz); //prints out java.lang.Integer

here is simple solution for that problem, no needs for that 'cat walk' on keyboard, i mean regex :)) enjoy ^-^

user = input('Input: ') # user = 'foobar12345'
int_list, str_list = [], []

for item in user:
 try:
    item = int(item)  # searching for integers in your string
  except:
    str_list.append(item)
    string = ''.join(str_list)
  else:  # if there are integers i will add it to int_list but as str, because join function only can work with str
    int_list.append(str(item))
    integer = int(''.join(int_list))  # if you want it to be string just do z = ''.join(int_list)

final = [string, integer]  # you can also add it to dictionary d = {string: integer}
print(final)

The 1st element as in no hard returns. A hard return I guess = an empty node/element in the DOM which becomes the 1st element disabling the doc compatability meta tag.

Apple released code at WWDC as a category on UIImage that includes this functionality, if you have a developer account you can grab the UIImage category (and the rest of the sample code) by going to this link: https://developer.apple.com/wwdc/schedule/ and browsing for section 226 and clicking on details. I haven't played around with it yet but I think the effect will be a lot slower on iOS 6, there are some enhancements to iOS 7 that make grabbing the initial screen shot that is used as input to the blur a lot faster.

As per machineAddict's comment, as of version 2 and later, year, month and day have been replaced by defaultDate, which is a Moment, supporting constructors such as an ISO 8601 date string or a Unix Epoch.

So e.g. to initialize the calendar with a given date:

$('#calendar').fullCalendar({
    defaultDate: moment('2014-09-01'),
    ...
});

The custom style sheets that we have are static pages in our local file system. In order for server to serve static files, we have to use,

app.use(express.static("public"));

where,

public is a folder we have to create inside our root directory and it must have other folders like css, images.. etc

The directory structure would look like :

Then in your html file, refer to the style.css as

<link type="text/css" href="css/styles.css" rel="stylesheet">

You could just define a new xml background in the drawables folder

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="enter_your_desired_color_here" />
<corners android:radius="enter_your_desired_radius_the_corners" />
</shape>  

After this just include it in your TextView or EditText by defining it in the background.

<TextView
 android:id="@+id/textView"
 android:layout_width="0dp"
 android:layout_height="80dp"
 android:background="YOUR_FILE_HERE"
 Android:layout_weight="1"
 android:gravity="center"
 android:text="TEXT_HERE"
 android:textSize="40sp" />

Try this:

package example.spin.spinnerexample;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity implements AdapterView.OnItemSelectedListener{

    String[] bankNames={"BOI","SBI","HDFC","PNB","OBC"};
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //Getting the instance of Spinner and applying OnItemSelectedListener on it
        Spinner spin = (Spinner) findViewById(R.id.simpleSpinner);
        spin.setOnItemSelectedListener(this);

        //Creating the ArrayAdapter instance having the bank name list
        ArrayAdapter aa = new ArrayAdapter(this,android.R.layout.simple_spinner_item,bankNames);
        aa.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        //Setting the ArrayAdapter data on the Spinner
        spin.setAdapter(aa);
    }


    //Performing action onItemSelected and onNothing selected
    @Override
    public void onItemSelected(AdapterView<?> arg0, View arg1, int position,long id) {
        Toast.makeText(getApplicationContext(), bankNames[position], Toast.LENGTH_LONG).show();
    }

    @Override
    public void onNothingSelected(AdapterView<?> arg0) {
        // TODO Auto-generated method stub

    }
}

activity_main.xml:-

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity">

    <Spinner
        android:id="@+id/simpleSpinner"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="100dp" />

</RelativeLayout>

Best practice is to open the source file (with a false visible status if you don't want to be bother) read your data and then we close it.

A working and clean code is avalaible on the link below :

Use the exact layout numbers described here and a nice blogpost here.

so:

layout := "2006-01-02T15:04:05.000Z"
str := "2014-11-12T11:45:26.371Z"
t, err := time.Parse(layout, str)

if err != nil {
    fmt.Println(err)
}
fmt.Println(t)

gives:

>> 2014-11-12 11:45:26.371 +0000 UTC

I know. Mind boggling. Also caught me first time. Go just doesn't use an abstract syntax for datetime components (YYYY-MM-DD), but these exact numbers (I think the time of the first commit of go Nope, according to this. Does anyone know?).

pyspark.sql.Column.contains() is only available in pyspark version 2.2 and above.

Just for the sake of completeness, here is a link to the golang documentation which describes all types. In your case it is numeric types:

uint8       the set of all unsigned  8-bit integers (0 to 255)
uint16      the set of all unsigned 16-bit integers (0 to 65535)
uint32      the set of all unsigned 32-bit integers (0 to 4294967295)
uint64      the set of all unsigned 64-bit integers (0 to 18446744073709551615)

int8        the set of all signed  8-bit integers (-128 to 127)
int16       the set of all signed 16-bit integers (-32768 to 32767)
int32       the set of all signed 32-bit integers (-2147483648 to 2147483647)
int64       the set of all signed 64-bit integers (-9223372036854775808 to 9223372036854775807)

float32     the set of all IEEE-754 32-bit floating-point numbers
float64     the set of all IEEE-754 64-bit floating-point numbers

complex64   the set of all complex numbers with float32 real and imaginary parts
complex128  the set of all complex numbers with float64 real and imaginary parts

byte        alias for uint8
rune        alias for int32

Which means that you need to use float64(integer_value).

I don't have experience with Django but the concepts from front-end to back-end and front-end framework to framework are the same.

1. React will consume your Django REST API. Front-ends and back-ends aren't connected in any way. React will make HTTP requests to your REST API in order to fetch and set data.
2. React, with the help of Webpack (module bundler) & Babel (transpiler), will bundle and transpile your Javascript into single or multiple files that will be placed in the entry HTML page. Learn Webpack, Babel, Javascript and React and Redux (a state container). I believe you won't use Django templating but instead allow React to render the front-end.
3. As this page is rendered, React will consume the API to fetch data so React can render it. Your understanding of HTTP requests, Javascript (ES6), Promises, Middleware and React is essential here.

Here are a few things I've found on the web that should help (based on a quick Google search):

• Django and React API Youtube tutorial
• Setting up Django with React (replaced broken link with archive.org link)
• Search for other resources using the bolded terms above. Try "Django React Webpack" first.

Hope this steers you in the right direction! Good luck! Hopefully others who specialize in Django can add to my response.

Summary

• Use test -n "${var-}" to check if the variable is not empty (and hence must be defined/set too). Usage:

  if test -n "${name-}"; then
    echo "name is set to $name"
  else
    echo "name is not set or empty"
  fi
  

• Use test ! -z "${var+}" to check if the variable is defined/set (even if it's empty). Usage:

  if test ! -z "${var+}"; then
    echo "name is set to $name"
  else
    echo "name is not set"
  fi
  
  

Note that the first use case is much more common in shell scripts and this is what you will usually want to use.

Notes

• This solution should work in all POSIX shells (sh, bash, zsh, ksh, dash)
• Some of the other answers for this question are correct but may be confusing for people unexperienced in shell scripting, so I wanted to provide a TLDR answer that will be least confusing for such people.

Explanation

To understand how this solution works, you need to understand the POSIX test command and POSIX shell parameter expansion (spec), so let's cover the absolute basics needed to understand the answer.

The test command evaluates an expression and returns true or false (via its exit status). The operator -n returns true if the operand is a non-empty string. So for example, test -n "a" returns true, while test -n "" returns false. Now, to check if a variable is not empty (which means it must be defined), you could use test -n "$var". However, some shell scripts have an option set (set -u) that causes any reference to undefined variables to emit an error, so if the variable var is not defined, the expression $a will cause an error. To handle this case correctly, you must use variable expansion, which will tell the shell to replace the variable with an alternative string if it's not defined, avoiding the aforementioned error.

The variable expansion ${var-} means: if the variable var is undefined (also called "unset"), replace it with an empty string. So test -n "${var-}" will return true if $var is not empty, which is almost always what you want to check in shell scripts. The reverse check, if $var is undefined or not empty, would be test -z "${var-}".

Now to the second use case: checking if the variable var is defined, whether empty or not. This is a less common use case and slightly more complex, and I would advise you to read Lionels's great answer to better understand it.

I use __dict__

Example:

class MyObj(object):
  def __init__(self):
    self.name = 'Chuck Norris'
    self.phone = '+6661'

obj = MyObj()
print(obj.__dict__)

# Output:  
# {'phone': '+6661', 'name': 'Chuck Norris'}

there is such a plugin as UniversalIndentGUI, it can be installed right from the plugin manager and has possibilities to reindent the most used programming languages.

rsubmit;
options missing=0;
ods listing close;
ods csv file='\\FILE_PATH_and_Name_of_report.csv';

proc sql;
SELECT *
FROM `YOUR_FINAL_TABLE_NAME';
quit;
ods csv close;

endrsubmit;

If it supports standard regex...

find:
^.*#RedirectMatch Permanent.*$

replace:

Replace with nothing.

Addressing cases that some of the other answers don't handle well:

• Responsive: direct execution of keypress handling code; avoids the vagaries of polling or blocking delays
• Optionality: global keypress is opt-in; otherwise the app should exit normally
• Separation of concerns: less invasive listening code; operates independently of normal console app code.

Many of the solutions on this page involve polling Console.KeyAvailable or blocking on Console.ReadKey. While it's true that the .NET Console is not very cooperative here, you can use Task.Run to move towards a more modern Async mode of listening.

The main issue to be aware of is that, by default, your console thread isn't set up for Async operation--meaning that, when you fall out of the bottom of your main function, instead of awaiting Async completions, your AppDoman and process will end. A proper way to address this would be to use Stephen Cleary's AsyncContext to establish full Async support in your single-threaded console program. But for simpler cases, like waiting for a keypress, installing a full trampoline may be overkill.

The example below would be for a console program used in some kind of iterative batch file. In this case, when the program is done with its work, normally it should exit without requiring a keypress, and then we allow an optional key press to prevent the app from exiting. We can pause the cycle to examine things, possibly resuming, or use the pause as a known 'control point' at which to cleanly break out of the batch file.

static void Main(String[] args)
{
    Console.WriteLine("Press any key to prevent exit...");
    var tHold = Task.Run(() => Console.ReadKey(true));

    // ... do your console app activity ...

    if (tHold.IsCompleted)
    {
#if false   // For the 'hold' state, you can simply halt forever...
        Console.WriteLine("Holding.");
        Thread.Sleep(Timeout.Infinite);
#else                            // ...or allow continuing to exit
        while (Console.KeyAvailable)
            Console.ReadKey(true);     // flush/consume any extras
        Console.WriteLine("Holding. Press 'Esc' to exit.");
        while (Console.ReadKey(true).Key != ConsoleKey.Escape)
            ;
#endif
    }
}

Mainly If you are using Linux Based system Like 'Ubuntu' and this is only suggested for localhost user not for the server.

Follow all the steps mentioned in the previous answers. +

Check in Apache configuration for it. (AllowOverride All) If AllowOverride value is none then change it to All and restart apache again.

This article can provide a lot of insight here: http://redis.io/topics/memory-optimization

There are many ways to store an array of Objects in Redis (spoiler: I like option 1 for most use cases):

1. Store the entire object as JSON-encoded string in a single key and keep track of all Objects using a set (or list, if more appropriate). For example:

   INCR id:users
   SET user:{id} '{"name":"Fred","age":25}'
   SADD users {id}
   

   Generally speaking, this is probably the best method in most cases. If there are a lot of fields in the Object, your Objects are not nested with other Objects, and you tend to only access a small subset of fields at a time, it might be better to go with option 2.

   Advantages: considered a "good practice." Each Object is a full-blown Redis key. JSON parsing is fast, especially when you need to access many fields for this Object at once. Disadvantages: slower when you only need to access a single field.

2. Store each Object's properties in a Redis hash.

   INCR id:users
   HMSET user:{id} name "Fred" age 25
   SADD users {id}
   

   Advantages: considered a "good practice." Each Object is a full-blown Redis key. No need to parse JSON strings. Disadvantages: possibly slower when you need to access all/most of the fields in an Object. Also, nested Objects (Objects within Objects) cannot be easily stored.

3. Store each Object as a JSON string in a Redis hash.

   INCR id:users
   HMSET users {id} '{"name":"Fred","age":25}'
   

   This allows you to consolidate a bit and only use two keys instead of lots of keys. The obvious disadvantage is that you can't set the TTL (and other stuff) on each user Object, since it is merely a field in the Redis hash and not a full-blown Redis key.

   Advantages: JSON parsing is fast, especially when you need to access many fields for this Object at once. Less "polluting" of the main key namespace. Disadvantages: About same memory usage as #1 when you have a lot of Objects. Slower than #2 when you only need to access a single field. Probably not considered a "good practice."

4. Store each property of each Object in a dedicated key.

   INCR id:users
   SET user:{id}:name "Fred"
   SET user:{id}:age 25
   SADD users {id}
   

   According to the article above, this option is almost never preferred (unless the property of the Object needs to have specific TTL or something).

   Advantages: Object properties are full-blown Redis keys, which might not be overkill for your app. Disadvantages: slow, uses more memory, and not considered "best practice." Lots of polluting of the main key namespace.

Overall Summary

Option 4 is generally not preferred. Options 1 and 2 are very similar, and they are both pretty common. I prefer option 1 (generally speaking) because it allows you to store more complicated Objects (with multiple layers of nesting, etc.) Option 3 is used when you really care about not polluting the main key namespace (i.e. you don't want there to be a lot of keys in your database and you don't care about things like TTL, key sharding, or whatever).

Inspired from @Hamed, I added the following and it worked for me:

display: inline-block; overflow: hidden; 

I was trying to format the date string received from a JSON response e.g. 2016-03-09T04:50:00-0800 to yyyy-MM-dd. So here's what I tried and it worked and helped me assign the formatted date string a calendar widget.

String DATE_FORMAT_I = "yyyy-MM-dd'T'HH:mm:ss";
String DATE_FORMAT_O = "yyyy-MM-dd";


SimpleDateFormat formatInput = new SimpleDateFormat(DATE_FORMAT_I);
SimpleDateFormat formatOutput = new SimpleDateFormat(DATE_FORMAT_O);

Date date = formatInput.parse(member.getString("date"));
String dateString = formatOutput.format(date);

This worked. Thanks.

The solution above won't work if the original string has no spaces.

Try this:

var title = "This is your title";
var shortText = jQuery.trim(title).substring(0, 10)
                          .trim(this) + "...";

What are they?

Nothing special. Just as same as common Java Class Instance.

But those class are Synthetic proxy classes created by java.lang.reflect.Proxy#newProxyInstance

What is there relationship to the JVM? Are they JVM implementation specific?

Introduced in 1.3

http://docs.oracle.com/javase/1.3/docs/relnotes/features.html#reflection

It is a part of Java. so each JVM should support it.

How are they created (Openjdk7 source)?

In short : they are created using JVM ASM tech ( defining javabyte code at runtime )

something using same tech:

• asm( http://asm.ow2.org/ )
• cglib( http://cglib.sourceforge.net/ )

What happens after calling java.lang.reflect.Proxy#newProxyInstance

1. reading the source you can see newProxyInstance call getProxyClass0 to obtain a `Class

   `

2. after lots of cache or sth it calls the magic ProxyGenerator.generateProxyClass which return a byte[]
3. call ClassLoader define class to load the generated $Proxy Class (the classname you have seen)
4. just instance it and ready for use

What happens in magic sun.misc.ProxyGenerator

1. draw a class(bytecode) combining all methods in the interfaces into one

2. each method is build with same bytecode like

   1. get calling Method meth info (stored while generating)
   2. pass info into invocation handler's invoke()
   3. get return value from invocation handler's invoke()
   4. just return it

3. the class(bytecode) represent in form of byte[]

How to draw a class

Thinking your java codes are compiled into bytecodes, just do this at runtime

Talk is cheap show you the code

The -S switch makes sudo read the password from STDIN. This means you can do

echo mypassword | sudo -S command

to pass the password to sudo

However, the suggestions by others that do not involve passing the password as part of a command such as checking if the user is root are probably much better ideas for security reasons

console.log('Hello, \n' + 
            'Text under your Header\n' + 
            '-------------------------\n' + 
            'More Text\n' +
            'Moree Text\n' +
            'Moooooer Text\n' );

This works great for me for text only, and easy on the eye.

You may want to take a look here, this tool saves a BAK file from a remote SQL Server to your local harddrive: FIDA BAK to local

You should also look at new triggers.

MySQL doesn't show the table name in the error, so you're really left in a lurch. Here's a working example:

use test;
create table blah (id int primary key AUTO_INCREMENT, data varchar(100));
create table audit_blah (audit_id int primary key AUTO_INCREMENT, action enum('INSERT','UPDATE','DELETE'), id int, data varchar(100) null);
insert into audit_blah(action, id, data) values ('INSERT', 1, 'a');
select * from blah;
select * from audit_blah;
truncate table audit_blah;

delimiter //
/* I've commented out "id" below, so the insert fails with an ambiguous error: */
create trigger ai_blah after insert on blah for each row 
begin 
  insert into audit_blah (action, /*id,*/ data) values ('INSERT', /*NEW.id,*/ NEW.data);
end;//

/* This insert is valid, but you'll get an exception from the trigger: */
insert into blah (data) values ('data1');

For powershell in Windows, you can add relative path + filename to --output flag:

curl -L  http://github.com/GorvGoyl/Notion-Boost-browser-extension/archive/master.zip --output build_firefox/master-repo.zip

here build_firefox is relative folder.

To replace a specific position:

s = s[:pos] + s[(pos+1):]

To replace a specific character:

s = s.replace('M','')

Your compiler just tried to compile the file named foo.cc. Upon hitting line number line, the compiler finds:

#include "bar"

or

#include <bar>

The compiler then tries to find that file. For this, it uses a set of directories to look into, but within this set, there is no file bar. For an explanation of the difference between the versions of the include statement look here.

How to tell the compiler where to find it

g++ has an option -I. It lets you add include search paths to the command line. Imagine that your file bar is in a folder named frobnicate, relative to foo.cc (assume you are compiling from the directory where foo.cc is located):

g++ -Ifrobnicate foo.cc

You can add more include-paths; each you give is relative to the current directory. Microsoft's compiler has a correlating option /I that works in the same way, or in Visual Studio, the folders can be set in the Property Pages of the Project, under Configuration Properties->C/C++->General->Additional Include Directories.

Now imagine you have multiple version of bar in different folders, given:

// A/bar
#include<string>
std::string which() { return "A/bar"; }

// B/bar
#include<string>
std::string which() { return "B/bar"; }

// C/bar
#include<string>
std::string which() { return "C/bar"; }

// foo.cc
#include "bar"
#include <iostream>

int main () {
    std::cout << which() << std::endl;
}

The priority with #include "bar" is leftmost:

$ g++ -IA -IB -IC foo.cc
$ ./a.out
A/bar

As you see, when the compiler started looking through A/, B/ and C/, it stopped at the first or leftmost hit.

This is true of both forms, include <> and incude "".

Difference between #include <bar> and #include "bar"

Usually, the #include <xxx> makes it look into system folders first, the #include "xxx" makes it look into the current or custom folders first.

E.g.:

Imagine you have the following files in your project folder:

list
main.cc

with main.cc:

#include "list"
....

For this, your compiler will #include the file list in your project folder, because it currently compiles main.cc and there is that file list in the current folder.

But with main.cc:

#include <list>
....

and then g++ main.cc, your compiler will look into the system folders first, and because <list> is a standard header, it will #include the file named list that comes with your C++ platform as part of the standard library.

This is all a bit simplified, but should give you the basic idea.

Details on <>/""-priorities and -I

According to the gcc-documentation, the priority for include <> is, on a "normal Unix system", as follows:

 /usr/local/include
 libdir/gcc/target/version/include
 /usr/target/include
 /usr/include

For C++ programs, it will also look in /usr/include/c++/version, first. In the above, target is the canonical name of the system GCC was configured to compile code for; [...].

The documentation also states:

You can add to this list with the -Idir command line option. All the directories named by -I are searched, in left-to-right order, before the default directories. The only exception is when dir is already searched by default. In this case, the option is ignored and the search order for system directories remains unchanged.

To continue our #include<list> / #include"list" example (same code):

g++ -I. main.cc

and

#include<list>
int main () { std::list<int> l; }

and indeed, the -I. prioritizes the folder . over the system includes and we get a compiler error.

You can use lodash. If lodash library is too heavy for your application consider chunking out unnecessary function not used.

let newArray = filter(_this.props.ArrayOne, function(item) {
                    return find(_this.props.ArrayTwo, {"speciesId": item.speciesId});
                });

This is just one way to do this. Another one can be:

var newArray=  [];
     _.filter(ArrayOne, function(item) {
                        return AllSpecies.forEach(function(cItem){
                            if (cItem.speciesId == item.speciesId){
                            newArray.push(item);
                          }
                        }) 
                    });

console.log(arr);

The above example can also be rewritten without using any libraries like:

var newArray=  [];
ArrayOne.filter(function(item) {
                return ArrayTwo.forEach(function(cItem){
                    if (cItem.speciesId == item.speciesId){
                    newArray.push(item);
                  }
                }) 
            });
console.log(arr);

Hope my answer helps.

same issue...resolved by dong the following

1.) close pm manager 2.) close Visual Studio 3.) Open Visual Studio 4.) Open pm manager

seems the trick is to close PM Manager before closing VS

Cookies are only sent at the time of the request, and therefore cannot be retrieved as soon as it is assigned (only available after reloading).

Once the cookies have been set, they can be accessed on the next page load with the $_COOKIE or $HTTP_COOKIE_VARS arrays.

If output exists prior to calling this function, setcookie() will fail and return FALSE. If setcookie() successfully runs, it will return TRUE. This does not indicate whether the user accepted the cookie.

Cookies will not become visible until the next loading of a page that the cookie should be visible for. To test if a cookie was successfully set, check for the cookie on a next loading page before the cookie expires. Expire time is set via the expire parameter. A nice way to debug the existence of cookies is by simply calling print_r($_COOKIE);.

If you want to extract a single file use:

gunzip file.gz

It will extract the file and remove .gz file.

You could use the substr function to return a substring starting from the 5th character:

$str = "The quick brown fox jumps over the lazy dog."
$str2 = substr($str, 4); // "quick brown fox jumps over the lazy dog."

The following answer is to merge data into same table

MERGE INTO YOUR_TABLE d
USING (SELECT 1 FROM DUAL) m
    ON ( d.USER_ID = '123' AND d.USER_NAME= 'itszaif') 
WHEN NOT MATCHED THEN
        INSERT ( d.USERS_ID, d.USER_NAME)
        VALUES ('123','itszaif');

This command checks if USER_ID and USER_NAME are matched, if not matched then it will insert.

The official answer from Facebook (http://developers.facebook.com/bugs/282710765082535):

Mikhail,

The facebook android sdk no longer supports android 1.5 and 1.6. Please upgrade to the next api version.

Good luck with your implementation.

if you need to close your application from main() you can use this code

int main(int argc, char *argv[]){
QApplication app(argc, argv);
...
if(!QSslSocket::supportsSsl()) return app.exit(0);
...
return app.exec();
}

The program will terminated if OpenSSL is not installed

A Popen object has a .wait() method exactly defined for this: to wait for the completion of a given subprocess (and, besides, for retuning its exit status).

If you use this method, you'll prevent that the process zombies are lying around for too long.

(Alternatively, you can use subprocess.call() or subprocess.check_call() for calling and waiting. If you don't need IO with the process, that might be enough. But probably this is not an option, because your if the two subprocesses seem to be supposed to run in parallel, which they won't with (check_)call().)

If you have several subprocesses to wait for, you can do

exit_codes = [p.wait() for p in p1, p2]

which returns as soon as all subprocesses have finished. You then have a list of return codes which you maybe can evaluate.

Push only work for array .

Make your arrayText object to Array Object.

Try Like this

JS

this.arrayText = [{
  text1: 'Hello',
  text2: 'world',
}];

this.addText = function(text) {
  this.arrayText.push(text);
}
this.form = {
  text1: '',
  text2: ''
};

HTML

<div ng-controller="TestController as testCtrl">
  <form ng-submit="addText(form)">
    <input type="text" ng-model="form.text1" value="Lets go">
    <input type="text" ng-model="form.text2" value="Lets go again">
    <input type="submit" value="add">
  </form>
</div>

The sendevent utility sends touch or keyboard events, as well as other events for simulating the hardware events. Refer to this article for details: Android, low level shell click on screen.

Using sessionStorage for this is not possible.

From the MDN Docs

Opening a page in a new tab or window will cause a new session to be initiated.

That means that you can't share between tabs, for this you should use localStorage

The "import" keyword is for attaching python definitions that are created external to the current python program. So in your case, where you just want to read a file with some text in it, use:

text = open("words.txt", "rb").read()

I found that use onclick='this.checked = false;' worked to a certain extent. A radio button that was clicked would not be selected. However, if there was a radio button that was already selected (e.g., a default value), that radio button would become unselected.

<!-- didn't completely work -->
<input type="radio" name="r1" id="r1" value="N" checked="checked" onclick='this.checked = false;'>N</input>
<input type="radio" name="r1" id="r1" value="Y" onclick='this.checked = false;'>Y</input>

For this scenario, leaving the default value alone and disabling the other radio button(s) preserves the already selected radio button and prevents it from being unselected.

<!-- preserves pre-selected value -->
<input type="radio" name="r1" id="r1" value="N" checked="checked">N</input>
<input type="radio" name="r1" id="r1" value="Y" disabled>Y</input>

This solution is not the most elegant way of preventing the default value from being changed, but it will work whether or not javascript is enabled.

No, I don't think you can append key/value pairs. The only thing closest that I am aware of is using the store method:

h = {}
h.store("key", "value")

From my understanding, the currently accepted answer only changes the order of the factor levels, not the actual labels (i.e., how the levels of the factor are called). To illustrate the difference between levels and labels, consider the following example:

Turn cyl into factor (specifying levels would not be necessary as they are coded in alphanumeric order):

    mtcars2 <- mtcars %>% mutate(cyl = factor(cyl, levels = c(4, 6, 8))) 
    mtcars2$cyl[1:5]
    #[1] 6 6 4 6 8
    #Levels: 4 6 8

Change the order of levels (but not the labels itself: cyl is still the same column)

    mtcars3 <- mtcars2 %>% mutate(cyl = factor(cyl, levels = c(8, 6, 4))) 
    mtcars3$cyl[1:5]
    #[1] 6 6 4 6 8
    #Levels: 8 6 4
    all(mtcars3$cyl==mtcars2$cyl)
    #[1] TRUE

Assign new labels to cyl The order of the labels was: c(8, 6, 4), hence we specify new labels as follows:

    mtcars4 <- mtcars3 %>% mutate(cyl = factor(cyl, labels = c("new_value_for_8", 
                                                               "new_value_for_6", 
                                                               "new_value_for_4" )))
    mtcars4$cyl[1:5]
    #[1] new_value_for_6 new_value_for_6 new_value_for_4 new_value_for_6 new_value_for_8
    #Levels: new_value_for_8 new_value_for_6 new_value_for_4

Note how this column differs from our first columns:

    all(as.character(mtcars4$cyl)!=mtcars3$cyl) 
    #[1] TRUE 
    #Note: TRUE here indicates that all values are unequal because I used != instead of ==
    #as.character() was required as the levels were numeric and thus not comparable to a character vector

More details:

If we were to change the levels of cyl using mtcars2 instead of mtcars3, we would need to specify the labels differently to get the same result. The order of labels for mtcars2 was: c(4, 6, 8), hence we specify new labels as follows

    #change labels of mtcars2 (order used to be: c(4, 6, 8)
    mtcars5 <- mtcars2 %>% mutate(cyl = factor(cyl, labels = c("new_value_for_4", 
                                                               "new_value_for_6", 
                                                               "new_value_for_8" )))

Unlike mtcars3$cyl and mtcars4$cyl, the labels of mtcars4$cyl and mtcars5$cyl are thus identical, even though their levels have a different order.

    mtcars4$cyl[1:5]
    #[1] new_value_for_6 new_value_for_6 new_value_for_4 new_value_for_6 new_value_for_8
    #Levels: new_value_for_8 new_value_for_6 new_value_for_4

    mtcars5$cyl[1:5]
    #[1] new_value_for_6 new_value_for_6 new_value_for_4 new_value_for_6 new_value_for_8
    #Levels: new_value_for_4 new_value_for_6 new_value_for_8

    all(mtcars4$cyl==mtcars5$cyl)
    #[1] TRUE

    levels(mtcars4$cyl) == levels(mtcars5$cyl)
    #1] FALSE  TRUE FALSE

It's a "pointer to member" - the following code illustrates its use:

#include <iostream>
using namespace std;

class Car
{
    public:
    int speed;
};

int main()
{
    int Car::*pSpeed = &Car::speed;

    Car c1;
    c1.speed = 1;       // direct access
    cout << "speed is " << c1.speed << endl;
    c1.*pSpeed = 2;     // access via pointer to member
    cout << "speed is " << c1.speed << endl;
    return 0;
}

As to why you would want to do that, well it gives you another level of indirection that can solve some tricky problems. But to be honest, I've never had to use them in my own code.

Edit: I can't think off-hand of a convincing use for pointers to member data. Pointer to member functions can be used in pluggable architectures, but once again producing an example in a small space defeats me. The following is my best (untested) try - an Apply function that would do some pre &post processing before applying a user-selected member function to an object:

void Apply( SomeClass * c, void (SomeClass::*func)() ) {
    // do hefty pre-call processing
    (c->*func)();  // call user specified function
    // do hefty post-call processing
}

The parentheses around c->*func are necessary because the ->* operator has lower precedence than the function call operator.

My own solution to solve this kind of Enum JPA mapping is the following.

Step 1 - Write the following interface that we will use for all enums that we want to map to a db column:

public interface IDbValue<T extends java.io.Serializable> {

    T getDbVal();

}

Step 2 - Implement a custom generic JPA converter as follows:

import javax.persistence.AttributeConverter;

public abstract class EnumDbValueConverter<T extends java.io.Serializable, E extends Enum<E> & IDbValue<T>>
        implements AttributeConverter<E, T> {

    private final Class<E> clazz;

    public EnumDbValueConverter(Class<E> clazz){
        this.clazz = clazz;
    }

    @Override
    public T convertToDatabaseColumn(E attribute) {
        if (attribute == null) {
            return null;
        }
        return attribute.getDbVal();
    }

    @Override
    public E convertToEntityAttribute(T dbData) {
        if (dbData == null) {
            return null;
        }
        for (E e : clazz.getEnumConstants()) {
            if (dbData.equals(e.getDbVal())) {
                return e;
            }
        }
        // handle error as you prefer, for example, using slf4j:
        // log.error("Unable to convert {} to enum {}.", dbData, clazz.getCanonicalName());
        return null;
    }

}

This class will convert the enum value E to a database field of type T (e.g. String) by using the getDbVal() on enum E, and vice versa.

Step 3 - Let the original enum implement the interface we defined in step 1:

public enum Right implements IDbValue<Integer> {
    READ(100), WRITE(200), EDITOR (300);

    private final Integer dbVal;

    private Right(Integer dbVal) {
        this.dbVal = dbVal;
    }

    @Override
    public Integer getDbVal() {
        return dbVal;
    }
}

Step 4 - Extend the converter of step 2 for the Right enum of step 3:

public class RightConverter extends EnumDbValueConverter<Integer, Right> {
    public RightConverter() {
        super(Right.class);
    }
}

Step 5 - The final step is to annotate the field in the entity as follows:

@Column(name = "RIGHT")
@Convert(converter = RightConverter.class)
private Right right;

Conclusion

IMHO this is the cleanest and most elegant solution if you have many enums to map and you want to use a particular field of the enum itself as mapping value.

For all others enums in your project that need similar mapping logic, you only have to repeat steps 3 to 5, that is:

• implement the interface IDbValue on your enum;
• extend the EnumDbValueConverter with only 3 lines of code (you may also do this within your entity to avoid creating a separated class);
• annotate the enum attribute with @Convert from javax.persistence package.

Hope this helps.

Try that:

if(WIN32)
    set(ADDITIONAL_LIBRARIES wsock32)
else()
    set(ADDITIONAL_LIBRARIES "")
endif()

target_link_libraries(${PROJECT_NAME} bioutils ${ADDITIONAL_LIBRARIES})

You can find other useful variables here.

color and fill are separate aesthetics. Since you want to modify the color you need to use the corresponding scale:

d + scale_color_manual(values=c("#CC6666", "#9999CC"))

is what you want.

I found this to be a little more accurate:

SELECT
   owner, table_name, TRUNC(sum(bytes)/1024/1024/1024) GB
FROM
(SELECT segment_name table_name, owner, bytes
FROM dba_segments
WHERE segment_type in  ('TABLE','TABLE PARTITION')
UNION ALL
SELECT i.table_name, i.owner, s.bytes
FROM dba_indexes i, dba_segments s
WHERE s.segment_name = i.index_name
AND   s.owner = i.owner
AND   s.segment_type in ('INDEX','INDEX PARTITION')
UNION ALL
SELECT l.table_name, l.owner, s.bytes
FROM dba_lobs l, dba_segments s
WHERE s.segment_name = l.segment_name
AND   s.owner = l.owner
AND   s.segment_type IN ('LOBSEGMENT','LOB PARTITION')
UNION ALL
SELECT l.table_name, l.owner, s.bytes
FROM dba_lobs l, dba_segments s
WHERE s.segment_name = l.index_name
AND   s.owner = l.owner
AND   s.segment_type = 'LOBINDEX')
---WHERE owner in UPPER('&owner')
GROUP BY table_name, owner
HAVING SUM(bytes)/1024/1024 > 10  /* Ignore really small tables */
ORDER BY SUM(bytes) desc

That delay you're talking about is actually a filter to prevent false (unwanted) orientation change notifications.

For instant recognition of device orientation change you're just gonna have to monitor the accelerometer yourself.

Accelerometer measures acceleration (gravity included) in all 3 axes so you shouldn't have any problems in figuring out the actual orientation.

Some code to start working with accelerometer can be found here:

How to make an iPhone App – Part 5: The Accelerometer

And this nice blog covers the math part:

old question, but posting this for fellow googlers:

Spin.js DOES WORK for this use case: http://fgnass.github.com/spin.js/

For me that solved it: https://coderwall.com/p/-ckobg

1. Open Project.xcodeproj > project.pbxproj
2. Remove all lines like these:
   1. PROVISIONING_PROFILE = ...
   2. "PROVISIONING_PROFILE[sdk=iphoneos*]" = ...
   3. CODE_SIGN_IDENTITY = ...
   4. "CODE_SIGN_IDENTITY[sdk=iphoneos*]" = ...
3. Set provisioning profiles & code signings for the target again

When you say "debug", do you mean actually launching the application from Visual Studio's built-in webserver for debugging, or do you mean attaching to the process in IIS? If it's the former, you should hit Application_Start, but if it's the latter, it can be difficult to be on the process early enough to catch it.

For me the query that is working, if I want to compare with DrawDate for example is:

CAST(DrawDate AS DATE) = CAST (GETDATE() as DATE)

This is comparing results with today's date.

or the whole query:

SELECT TOP (1000) *
FROM test
where DrawName != 'NULL' and CAST(DrawDate AS DATE) = CAST (GETDATE() as DATE)
order by id desc

The simplest way is to use the following pattern:

http://[server]/[site]/[ListName]/[Folder]/[SubFolder]

To place a shortcut to a document library:

1. Upload it as *.url file. However, by default, this file type is not allowed.
2. Go to you Document Library settings > Advanced Settings > Allow management of content types. Add the "Link to document" content type to a document library and paste the link

As a careful programmer will often throw an exception for a special occurrence, it worth mentioning some general purpose exceptions like IllegalArgumentException and IllegalStateException and UnsupportedOperationException. IllegalArgumentException is my favorite:

throw new IllegalArgumentException("Word contains blank: " + word);

In bash, we use

declare -A name_of_dictonary_variable

so that Bash understands it is a dictionary.

For e.g. you want to create sounds dictionary then,

declare -A sounds

sounds[dog]="Bark"

sounds[wolf]="Howl"

where dog and wolf are "keys", and Bark and Howl are "values".

You can access all values using : echo ${sounds[@]} OR echo ${sounds[*]}

You can access all keys only using: echo ${!sounds[@]}

And if you want any value for a particular key, you can use:

${sounds[dog]}

this will give you value (Bark) for key (Dog).

This is my implementation of RotatableImageView. Usage is very easy: just copy attrs.xml and RotatableImageView.java into your project and add RotatableImageView to your layout. Set desired rotation angle using example:angle parameter.

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:example="http://schemas.android.com/apk/res/com.example"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <com.example.views.RotatableImageView
        android:id="@+id/layout_example_image"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:adjustViewBounds="true"
        android:scaleType="fitCenter"
        android:src="@drawable/ic_layout_arrow"
        example:angle="180" />
</FrameLayout>

If you have some problems with displaying image, try change code in RotatableImageView.onDraw() method or use draw() method instead.

I have used this code which worked

                if (element.HasAttributes) {

                    foreach(var attr in element.Attributes().Reverse())
                    {

                        if (depth > 1)
                        {
                            elements_upper_hierarchy_text = "";
                            foreach (var ancest  in element.Ancestors().Reverse())
                            {
                                elements_upper_hierarchy_text += ancest.Name + "_";
                            }// foreach(var ancest  in element.Ancestors())

                        }//if (depth > 1)
                        xml_taglist_report += " " + depth  + " " + elements_upper_hierarchy_text+ element.Name + "_" + attr.Name +"(" + attr.Name +")" + "   =   " + attr.Value + "\r\n";
                    }// foreach(var attr in element.Attributes().Reverse())

                }// if (element.HasAttributes) {

OnRequestPermissionResult-free and shouldShowRequestPermissionRationale-free method:

public static void requestDangerousPermission(AppCompatActivity activity, String permission) {
        if (hasPermission(activity, permission)) return;
        requestPermission();

        new Handler().postDelayed(() -> {
            if (activity.getLifecycle().getCurrentState() == Lifecycle.State.RESUMED) {
                Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
                intent.setData(Uri.parse("package:" + context.getPackageName()));
                context.startActivity(intent);
            }
        }, 250);
    }

Opens device settings after 250ms if no permission popup happened (which is the case if 'Never ask again' was selected.

Addendum to @sjngm's answer:

They both also ignore whitespace:

var foo = " 3 "; console.log(parseInt(foo)); // 3 console.log(Number(foo)); // 3

It is not exactly correct. As sjngm wrote parseInt parses string to first number. It is true. But the problem is when you want to parse number separated with whitespace ie. "12 345". In that case
parseInt("12 345") will return 12 instead of 12345. So to avoid that situation you must trim whitespaces before parsing to number. My solution would be:

     var number=parseInt("12 345".replace(/\s+/g, ''),10);

Notice one extra thing I used in parseInt() function. parseInt("string",10) will set the number to decimal format. If you would parse string like "08" you would get 0 because 8 is not a octal number.Explanation is here

I think this solution is handy if you can test the value of the error field later. This is also applicable by creating a temporary table and returning a list of errors.

DROP PROCEDURE IF EXISTS $procName;
DELIMITER //
CREATE PROCEDURE $procName($params)
BEGIN
    DECLARE error INT DEFAULT 0;
    DECLARE CONTINUE HANDLER FOR NOT FOUND SET error = 1;
    SELECT
       $fields
    FROM $tables
    WHERE $where
    ORDER BY $sorting LIMIT 1
    INTO $vars;
    IF error = 0 THEN
       SELECT $vars;
    ELSE
       SELECT 1 AS error;
       SET @error = 0;
    END IF;
END//
CALL $procName($effp);

For more generalised cases (including numbers with decimal point), you can try the following method:

def number?(obj)
  obj = obj.to_s unless obj.is_a? String
  /\A[+-]?\d+(\.[\d]+)?\z/.match(obj)
end

You can test this method in an irb session:

(irb)
>> number?(7)
=> #<MatchData "7" 1:nil>
>> !!number?(7)
=> true
>> number?(-Math::PI)
=> #<MatchData "-3.141592653589793" 1:".141592653589793">
>> !!number?(-Math::PI)
=> true
>> number?('hello world')
=> nil
>> !!number?('hello world')
=> false

This looks a little ugly. Is it possible to cast an entire stream to a different type? Like cast Stream<Object> to a Stream<Client>?

No that wouldn't be possible. This is not new in Java 8. This is specific to generics. A List<Object> is not a super type of List<String>, so you can't just cast a List<Object> to a List<String>.

Similar is the issue here. You can't cast Stream<Object> to Stream<Client>. Of course you can cast it indirectly like this:

Stream<Client> intStream = (Stream<Client>) (Stream<?>)stream;

but that is not safe, and might fail at runtime. The underlying reason for this is, generics in Java are implemented using erasure. So, there is no type information available about which type of Stream it is at runtime. Everything is just Stream.

BTW, what's wrong with your approach? Looks fine to me.

Try the following steps:
1. Make sure you have the latest npm (npm install -g npm).
2. Add an exception to your antivirus to ignore the node_modules folder in your project.
3. $ rm -rf node_modules package-lock.json .
4. $ npm install

More efficient and easy way to print the 2D array in a formatted way:

Try this:

public static void print(int[][] puzzle) {
        for (int[] row : puzzle) {
            for (int elem : row) {
                System.out.printf("%4d", elem);
            }
            System.out.println();
        }
        System.out.println();
    }

Sample Output:

   0   1   2   3
   4   5   6   7
   8   9  10  11
  12  13  14  15

Use varchar instead of VAR_CHAR and omit the comma in the last line i.e.phone INT NOT NULL );. The last line during creating table is kept "comma free". Ex:- CREATE TABLE COMPUTER ( Model varchar(50) ); Here, since we have only one column ,that's why there is no comma used during entire code.

3. A center tag is not the same as a div with text-align:center;
4. The fact that you have another way to do something doesn't make it invalid.

Let me explain because there are notorious downvoters here who will think I'm defending oldschool HTML4 or something. No I'm not. But the debate around center is simply a trend war, there is no real reason to ditch a tag that serves a valid purpose well.

So let's see the major arguments against it.

• "It describes presentation, not semantics!"
  No. It describes a logical arrangement - and yes, it has a default appearance, just as other tags like <p> or <ul> do. But the point is the enclosed part's relation to its surroundings. Center says "this is something we separate by visually different positioning".

• "It's not valid"
  Yes it is. It's just deprecated, as in, could be removed later. For 15+ years now. And it's not going anywhere, apparently. There are major sites (including google.com) that use this tag because it's very readable and to the point - and those are the same reasons we like HTML5 tags for.

• "It's not supported in HTML5"
  It's one of the most widely supported tags, actually. MDN says "its use is discouraged since it could be removed at any time" - good point, but that day may never come, to quote a classic. Center was already deprecated in like 2004 or so - it's still here and still useful.

• "It's oldschool"
  Shoelaces are oldschool too. New methods don't invalidate the old. You want to feel progressive and modern: fine. But don't make it the law.

• "It's stupid / awkward / lame / tells a story about you"
  None of these. It's like a hammer: one tool for a specific job. There are other tools for the same job and other jobs for the same tool; but it was created to solve a certain problem and that problem is still around so we might as well just use a dedicated solution.

• "You shouldn't do this, because, CSS"
  Centering can absolutely be achieved by CSS but that's just one way, not the only one, let alone the only appropriate one. Anything that's supported, working and readable should be ok to use. Also, the same argument happened before flexboxes and CSS grids, which is funny because back then there was no CSS way to achieve what center did. No, text-align:center is not the same. No, margin:auto is not the same. Anyone who argued against center tags before flexbox simply didn't know enough about CSS.

TL;DR:

The only reason not to use <center> is because people will hate you.

Based on the answers above, but adding a Func-parameter to let the caller handle the duplicates:

public static Dictionary<TKey, TValue> Merge<TKey, TValue>(this IEnumerable<Dictionary<TKey, TValue>> dicts, 
                                                           Func<IGrouping<TKey, TValue>, TValue> resolveDuplicates)
{
    if (resolveDuplicates == null)
        resolveDuplicates = new Func<IGrouping<TKey, TValue>, TValue>(group => group.First());

    return dicts.SelectMany<Dictionary<TKey, TValue>, KeyValuePair<TKey, TValue>>(dict => dict)
                .ToLookup(pair => pair.Key, pair => pair.Value)
                .ToDictionary(group => group.Key, group => resolveDuplicates(group));
}

I too had this problem on SQL Server 2014 while logging with windows Authentication, to resolve the issue i have Restarted my server once and then try to login, it worked for me.

I see the many types of uses, but I find this layout more useful as a reference tool:

SELECT DATE_FORMAT('2004-01-20' ,'%Y-%m-01');

I'm not sure if this is the simplest or best way, or if there are any pitfalls, but it works:

static public LocalDateTime toLdt(Date date) {
    GregorianCalendar cal = new GregorianCalendar();
    cal.setTime(date);
    ZonedDateTime zdt = cal.toZonedDateTime();
    return zdt.toLocalDateTime();
}

static public Date fromLdt(LocalDateTime ldt) {
    ZonedDateTime zdt = ZonedDateTime.of(ldt, ZoneId.systemDefault());
    GregorianCalendar cal = GregorianCalendar.from(zdt);
    return cal.getTime();
}

Use ngInit: https://docs.angularjs.org/api/ng/directive/ngInit

<div ng-repeat="day in forecast_days" ng-init="f = forecast[day.iso]">
  {{$index}} - {{day.iso}} - {{day.name}}
  Temperature: {{f.temperature}}<br>
  Humidity: {{f.humidity}}<br>
  ...
</div>

This sets the scrollbar width:

::-webkit-scrollbar {
  width: 8px;   // for vertical scroll bar
  height: 8px;  // for horizontal scroll bar
}

// for Firefox add this class as well
.thin_scroll{
  scrollbar-width: thin; // auto | thin | none | <length>;
}

Why not use document.documentMode only available under IE:

var doc = $window.document;
if (!!doc.documentMode)
{
  if (doc.documentMode === 10)
  {
    doc.documentElement.className += ' isIE isIE10';
  }
  else if (doc.documentMode === 11)
  {
    doc.documentElement.className += ' isIE isIE11';
  }
  // etc.
}

Though there have been considerable advancements in Java's GC technology, you still need to be mindful of your references. Numerous cases of seemingly trivial reference patterns that are actually rats nests under the hood come to mind.

From your post it doesn't sound like you're trying to implement a reset method for the purpose of object reuse (true?). Are your objects holding any other type of resources that need to be cleaned up (i.e., streams that must be closed, any pooled or borrowed objects that must be returned)? If the only thing you're worried about is memory dealloc then I would reconsider my object structure and attempt to verify that my objects are self contained structures that will be cleaned up at GC time.

If you're using a Storyboard and you're coming from a push segue, you could also just override shouldPerformSegueWithIdentifier:sender:.

If the true intent of the question is the comparison between dicts (rather than printing differences), the answer is

dict1 == dict2

This has been mentioned before, but I felt it was slightly drowning in other bits of information. It might appear superficial, but the value comparison of dicts has actually powerful semantics. It covers

• number of keys (if they don't match, the dicts are not equal)
• names of keys (if they don't match, they're not equal)
• value of each key (they have to be '==', too)

The last point again appears trivial, but is acutally interesting as it means that all of this applies recursively to nested dicts as well. E.g.

 m1 = {'f':True}
 m2 = {'f':True}
 m3 = {'a':1, 2:2, 3:m1}
 m4 = {'a':1, 2:2, 3:m2}
 m3 == m4  # True

Similar semantics exist for the comparison of lists. All of this makes it a no-brainer to e.g. compare deep Json structures, alone with a simple "==".

You can use request-ip, to retrieve a user's ip address. It handles quite a few of the different edge cases, some of which are mentioned in the other answers.

Disclosure: I created this module

Install:

npm install request-ip

In your app:

var requestIp = require('request-ip');

// inside middleware handler
var ipMiddleware = function(req, res, next) {
    var clientIp = requestIp.getClientIp(req); // on localhost > 127.0.0.1
    next();
};

Hope this helps

In my case I only need to add to project's build.gradle file:

android {
  packagingOptions {
    exclude 'META-INF/notice.txt'
    exclude 'META-INF/license.txt'
  }

   ...
}

You will need to create a virtual device that runs on ARM. Virtual devices running on X86 require an Intel processor. AMD support as specified by Android is only available for Linux systems. If you want a better experience when creating your Virtual Device, use "Store a snapshot for faster startup" instead of the default "Use Host GPU".

hashMaps can't have duplicate keys. That said, you can create a map with list values:

Map<Integer, List<String>>

However, using this approach will have performance implications.

For SwiftUI

If you are making your own TextView using UIViewRepresentable and want to control the padding, in your makeUIView function, simply do:

uiTextView.textContainerInset = UIEdgeInsets(top: 10, left: 18, bottom: 0, right: 18)

or whatever you want.

Consider using subtree instead of submodules, it will make your repo users life much easier. You may find more detailed guide in Pro Git book.

You need to use entryComponents under @NgModule.

This is for dynamically added components that are added using ViewContainerRef.createComponent(). Adding them to entryComponents tells the offline template compiler to compile them and create factories for them.

The components registered in route configurations are added automatically to entryComponents as well because router-outlet also uses ViewContainerRef.createComponent() to add routed components to the DOM.

So your code will be like

@NgModule({
  declarations: [
    AppComponent,
    LoginComponent,
    DashboardComponent,
    HomeComponent,
    DialogResultExampleDialog        
  ],
  entryComponents: [DialogResultExampleDialog]

This situation happens when the IDE looks for src folder, and it cannot find it in the path. Select the project root (F4 in windows) > Go to Modules on Side Tab > Select Sources > Select appropriate folder with source files in it> Click on the blue sources folder icon (for adding sources) > Click on Green Test Sources folder ( to add Unit test folders).

(long dead question, but for future searchers)

Closer to the original poster's code/intent, this works for me under python 2.6

#!/usr/bin/python
import logging

logger = logging.getLogger() # this gets the root logger

lhStdout = logger.handlers[0]  # stdout is the only handler initially

# ... here I add my own handlers 
f = open("/tmp/debug","w")          # example handler
lh = logging.StreamHandler(f)
logger.addHandler(lh)

logger.removeHandler(lhStdout)

logger.debug("bla bla")

The gotcha I had to work out was to remove the stdout handler after adding a new one; the logger code appears to automatically re-add the stdout if no handlers are present.

Use this query:

UPDATE `table` SET date_date=now();

Sample code can be:

<?php
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("my_db", $con);

mysql_query("UPDATE `table` SET date_date=now()");

mysql_close($con);
?>

This has nothing to do with a malformed upload. The HTTP error clearly specifies 401 unauthorized, and tells you the CSRF token is invalid. Try sending a valid CSRF token with the upload.

The documentation says:

class (Optional) String
One or more CSS classes to remove from the elements, these are separated by spaces.

Example:

Remove the class 'blue' and 'under' from the matched elements.

$("p:odd").removeClass("blue under");

const foo = 'bar';
console.log(!!foo); // Boolean: true

! negates (inverts) a value AND always returns/ produces a boolean. So !'bar' would yield false (because 'bar' is truthy => negated + boolean = false). With the additional ! operator, the value is negated again, so false becomes true.

Brighams answer uses literal regexp.

Solution with a Regex object.

var regex = new RegExp('\n', 'g');
text = text.replace(regex, '<br />');

I was facing the same issue in windows7, as i just recoverd my computer with the help of recovery point and after that notebook just stopped working. I tried to change the path setting but nothing was working so I just simply uninstalled the python with the application from which it was installed and after that I installed it again. After that I installed jupyter notebook again and then it worked fine. Thanks

Whenever you change the email field, the link is updated automatically. This requires a small amount of jQuery. So now your form will work as needed, but your link will be updated dynamically so that when someone clicks on it, it contains what they entered in the email field. You should validate the input on the receiving page.

$('input[name="email"]').change(function(){
  $('#regLink').attr('href')+$('input[name="email"]').val();
});

None of the existing answers worked for me.

I was using worktrees, so there is no .git folder.

You'll need to go back to your main repo. Inside that, delete .git/worktrees/<name_of_tree>/index

Then run git reset as per other answers.

<?php
$start = strtotime("12:00");
$end = // Run query to get datetime value from db
$elapsed = $end - $start;
echo date("H:i", $elapsed);
?>
