In my case it was simply that I had a variable named the same as a function.

Example:

def cleanCache = functionReturningABoolean()

if( cleanCache ){
    echo "Clean cache option is true, do not uninstall previous features / urls"
    uninstallCmd = ""
    
    // and we call the cleanCache method
    cleanCache(userId, serverName)
}
...

and later in my code I have the function:

def cleanCache(user, server){

 //some operations to the server

}

Apparently the Groovy language does not support this (but other languages like Java does). I just renamed my function to executeCleanCache and it works perfectly (or you can also rename your variable whatever option you prefer).

I got this exception while testing out some code a coworker had written. Here is a summary of the exception info.:

Method not found: "System.Threading.Tasks.Task1<Microsoft.EntityFrameworkCore.ChangeTracking.EntityEntry1<System_Canon>> Microsoft.EntityFrameworkCore.DbSet`1.AddAsync...

This was in Visual Studio 2019 in a class library targeting .NET Core 3.1. The fix was to use the Add method instead of AddAsync on the DbSet.

While this may be obvious to some, the culprit of this error for me was my MVC method was binding to a model that contained a property of type Tuple<>. Tuple<> has no parameterless constructor.

const getFirstWord = string => {
    const firstWord = [];
    for (let i = 0; i < string.length; i += 1) {
        if (string[i] === ' ') break;
        firstWord.push(string[i]);
    }
    return firstWord.join('');
};
console.log(getFirstWord('Hello World'));

or simplify it:

const getFirstWord = string => {
    const words = string.split(' ');
    return words[0];
};
console.log(getFirstWord('Hello World'));

2019 Laravel Update, Never thought i will post this but for those developers like me using the browser fetch api on Laravel 5.8 and above. You have to pass your token via the headers parameter.

var _token = "{{ csrf_token }}";
fetch("{{url('add/new/comment')}}", {
                method: 'POST',
                headers: {

                body: JSON.stringify(name, email, message, article_id)
            }).then(r => {
                return r.json();

I think the answer by jpmc26, while by no means wrong, comes down too heavily on circular imports. They can work just fine, if you set them up correctly.

The easiest way to do so is to use import my_module syntax, rather than from my_module import some_object. The former will almost always work, even if my_module included imports us back. The latter only works if my_object is already defined in my_module, which in a circular import may not be the case.

To be specific to your case: Try changing entities/post.py to do import physics and then refer to physics.PostBody rather than just PostBody directly. Similarly, change physics.py to do import entities.post and then use entities.post.Post rather than just Post.

Another option, if you're using temporary tables instead of staging tables, could be to create the temporary table as your import expects, then add the identity column after the import.

So your sql does something like this:

1. If temp table exists, drop
2. Create temp table
3. Bulk Import to temp table
4. Alter temp table add identity
5. < whatever you want to do with the data >
6. Drop temp table

Still not very clean, but it's another option... might have to get locks to be safe, too.

This will give you a list.

List<Card> cardsList = Arrays.asList(hand);

If you want an arraylist, you can do

ArrayList<Card> cardsList = new ArrayList<Card>(Arrays.asList(hand));

The error you're getting appears to be the result of the fact that there is no underscore between "chartered" and "flight" in the table name. I assume you want something like this where the name of the table is chartered_flight.

CREATE TABLE chartered_flight(flight_no NUMBER(4) PRIMARY KEY
, customer_id NUMBER(6) REFERENCES customer(customer_id)
, aircraft_no NUMBER(4) REFERENCES aircraft(aircraft_no)
, flight_type VARCHAR2 (12)
, flight_date DATE NOT NULL
, flight_time INTERVAL DAY TO SECOND NOT NULL
, takeoff_at CHAR (3) NOT NULL
, destination CHAR (3) NOT NULL)

Generally, there is no benefit to declaring a column as CHAR(3) rather than VARCHAR2(3). Declaring a column as CHAR(3) doesn't force there to be three characters of (useful) data. It just tells Oracle to space-pad data with fewer than three characters to three characters. That is unlikely to be helpful if someone inadvertently enters an incorrect code. Potentially, you could declare the column as VARCHAR2(3) and then add a CHECK constraint that LENGTH(takeoff_at) = 3.

CREATE TABLE chartered_flight(flight_no NUMBER(4) PRIMARY KEY
, customer_id NUMBER(6) REFERENCES customer(customer_id)
, aircraft_no NUMBER(4) REFERENCES aircraft(aircraft_no)
, flight_type VARCHAR2 (12)
, flight_date DATE NOT NULL
, flight_time INTERVAL DAY TO SECOND NOT NULL
, takeoff_at CHAR (3) NOT NULL CHECK( length( takeoff_at ) = 3 )
, destination CHAR (3) NOT NULL CHECK( length( destination ) = 3 )
)

Since both takeoff_at and destination are airport codes, you really ought to have a separate table of valid airport codes and define foreign key constraints between the chartered_flight table and this new airport_code table. That ensures that only valid airport codes are added and makes it much easier in the future if an airport code changes.

And from a naming convention standpoint, since both takeoff_at and destination are airport codes, I would suggest that the names be complementary and indicate that fact. Something like departure_airport_code and arrival_airport_code, for example, would be much more meaningful.

You can get raw data using below method. BTW, this pattern is for Java 6. If you are using Java 7 or newer, please consider try-with-resources pattern.

public String getJSON(String url, int timeout) {
    HttpURLConnection c = null;
    try {
        URL u = new URL(url);
        c = (HttpURLConnection) u.openConnection();
        c.setRequestMethod("GET");
        c.setRequestProperty("Content-length", "0");
        c.setUseCaches(false);
        c.setAllowUserInteraction(false);
        c.setConnectTimeout(timeout);
        c.setReadTimeout(timeout);
        c.connect();
        int status = c.getResponseCode();

        switch (status) {
            case 200:
            case 201:
                BufferedReader br = new BufferedReader(new InputStreamReader(c.getInputStream()));
                StringBuilder sb = new StringBuilder();
                String line;
                while ((line = br.readLine()) != null) {
                    sb.append(line+"\n");
                }
                br.close();
                return sb.toString();
        }

    } catch (MalformedURLException ex) {
        Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
    } catch (IOException ex) {
        Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
    } finally {
       if (c != null) {
          try {
              c.disconnect();
          } catch (Exception ex) {
             Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
          }
       }
    }
    return null;
}

And then you can use returned string with Google Gson to map JSON to object of specified class, like this:

String data = getJSON("http://localhost/authmanager.php");
AuthMsg msg = new Gson().fromJson(data, AuthMsg.class);
System.out.println(msg);

There is a sample of AuthMsg class:

public class AuthMsg {
    private int code;
    private String message;

    public int getCode() {
        return code;
    }
    public void setCode(int code) {
        this.code = code;
    }

    public String getMessage() {
        return message;
    }
    public void setMessage(String message) {
        this.message = message;
    }
}

JSON returned by http://localhost/authmanager.php must look like this:

{"code":1,"message":"Logged in"}

Today 2020.12.04 I perform tests on MacOs HighSierra 10.13.6 on Chrome v86, Safari v13.1.2 and Firefox v83 for chosen solutions.

Results

For all browsers

• in-place solution based on length (B) is fastest for small arrays, and in Firefox for big too and for Chrome and Safari is fast
• in-place solution based on push (A) is fastest for big arrays on Chrome and Safari, and fast for Firefox and small arrays
• in-place solution C is slow for big arrays and medium fast for small
• non-in-place solutions D and E are slow for big arrays
• non-in-place solutions E,F and D(on Firefox) are slow for small arrays

Details

I perform 2 tests cases:

• for small array with 10 elements - you can run it HERE
• for big array with 1M elements - you can run it HERE

For restarting the animation of a gif image, you can use the code:

$('#img_gif').attr('src','file.gif?' + Math.random());

You could try the same address with HTTP instead of HTTPS. Be aware that this does use HTTP instead of HTTPS and only some sites might support this method.

Example address: https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-10.3.0-amd64-netinst.iso

wget http://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-10.3.0-amd64-netinst.iso

*notice the http:// instead of https://.

This is probably not recommended though :)

If you can, try use curl.

EDIT:

FYI an example with username (and prompt for password) would be:

curl --user $USERNAME -O http://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-10.3.0-amd64-netinst.iso

Where -O is

 -O, --remote-name
              Write output to a local file named like the remote file we get. (Only the file part of the remote file is used, the path is cut off.)

A var cannot be set to null since it needs to be statically typed.

var foo = null;
// compiler goes: "Huh, what's that type of foo?"

However, you can use this construct to work around the issue:

var foo = (string)null;
// compiler goes: "Ah, it's a string. Nice."

I don't know for sure, but from what I heard you can also use dynamic instead of var. This does not require static typing.

dynamic foo = null;
foo = "hi";

Also, since it was not clear to me from the question if you meant the varkeyword or variables in general: Only references (to classes) and nullable types can be set to null. For instance, you can do this:

string s = null; // reference
SomeClass c = null; // reference
int? i = null; // nullable

But you cannot do this:

int i = null; // integers cannot contain null

The following should do the trick - Only SqlServer

You might want to check out Remy Sharp's recent article on fixed floating elements at jQuery for Designers, which has a nice video and writeup on how to apply this effect in client script

Use Cheerio. It isn't as strict as jsdom and is optimized for scraping. As a bonus, uses the jQuery selectors you already know.

? Familiar syntax: Cheerio implements a subset of core jQuery. Cheerio removes all the DOM inconsistencies and browser cruft from the jQuery library, revealing its truly gorgeous API.

? Blazingly fast: Cheerio works with a very simple, consistent DOM model. As a result parsing, manipulating, and rendering are incredibly efficient. Preliminary end-to-end benchmarks suggest that cheerio is about 8x faster than JSDOM.

? Insanely flexible: Cheerio wraps around @FB55's forgiving htmlparser. Cheerio can parse nearly any HTML or XML document.

You don't need quotes around the variable, so simply change this:

Get-ADComputer -Filter {name -like '$nameregex' -and Enabled -eq "true"}

into this:

Get-ADComputer -Filter {name -like $nameregex -and Enabled -eq "true"}

Note, however, that the scriptblock notation for filter statements is misleading, because the statement is actually a string, so it's better to write it as such:

Get-ADComputer -Filter "name -like '$nameregex' -and Enabled -eq 'true'"

Related. Also related.

And FTR: you're using wildcard matching here (operator -like), not regular expressions (operator -match).

You can improve the speed of your code if you restrict the items jQuery will look at.

Use the selector :input instead of * to achieve it.

$('#divId :input').serialize()

This will make your code faster because the list of items is shorter.

I added this to Espuz and JCC's answer. It uses the y position of the subviews and doesn't include the scroll bars. Edit Uses the bottom of the lowest sub view that is visible.

Surprised that no one suggested it:

System.DateTime.UtcNow.ToString("u").Replace(' ','T')

# Using PowerShell Core to demo

# Lowercase "u" format
[System.DateTime]::UtcNow.ToString("u")

# Lowercase "u" format with replacement
[System.DateTime]::UtcNow.ToString("u").Replace(' ','T')
> 2020-02-06T01:00:32Z

The UniversalSortableDateTimePattern gets you almost all the way to what you want (which is more an RFC 3339 representation).

If we are using apache commons logging wrapper on top of log4j, then we need to have both the jars available in classpath. Also, commons-logging.properties and log4j.properties/xml should be available in classpath.

We can also pass implementation class and log4j.properties name as JAVA_OPTS either using -Dorg.apache.commons.logging.Log=<logging implementation class name> -Dlog4j.configuration=<file:location of log4j.properties/xml file>. Same can be done via setting JAVA_OPTS in case of app/web server.

It will help to externalize properties which can be changed in deployment.

If you're using a scanner, in your scanner try to have it return the least number of qualifiers as possible. In fact, the qualifier(s) that you do return should be the smallest (in byte-size) as you have available. This will speed up your scan tremendously.

Unfortuneately this will only scale so far (millions-billions?). To take it further, you can do this in real time but you will first need to run a mapreduce job to count all rows.

Store the Mapreduce output in a cell in HBase. Every time you add a row, increment the counter by 1. Every time you delete a row, decrement the counter.

When you need to access the number of rows in real time, you read that field in HBase.

There is no fast way to count the rows otherwise in a way that scales. You can only count so fast.

This error is happening because you are just opening html documents directly from the browser. To fix this you will need to serve your code from a webserver and access it on localhost. If you have Apache setup, use it to serve your files. Some IDE's have built in web servers, like JetBrains IDE's, Eclipse...

If you have Node.Js setup then you can use http-server. Just run npm install http-server -g and you will be able to use it in terminal like http-server C:\location\to\app. Kirill Fuchs

Install this plugin for jquery and use it

http://plugins.jquery.com/project/jqueryenabledisable

It allows you to disable/enable pretty much any field in the page.

If you want to open a page on some condition write a java script function and call it from href. If the condition satisfied you open page otherwise just do nothing.

code looks like this:

<a href="javascript: openPage()" >Click here</a>

and function:
function openPage()
{
if(some conditon)
opener.document.location = "http://www.google.com";
}
}

You can also put the link in a div and set the display property of the Style attribute to none. this will hide the div. For eg.,

<div id="divid" style="display:none">
<a href="Hiding Link" />
</div>

This will hide the link. Use a button or an image to make this div visible now by calling this function in onclick as:

<a href="Visible Link" onclick="showDiv()">

and write the js code as:

function showDiv(){
document.getElememtById("divid").style.display="block";
}

You can also put an id tag to the html tag, so it would be

<a id="myATag" href="whatever"></a>

And get this id on your javascript by using

document.getElementById("myATag").value="#"; 

One of this must work for sure haha

Use the preprocessor:

#define VISIT_ERROR(FIRST, MIDDLE, LAST) \
    FIRST(ErrorA) MIDDLE(ErrorB) /* MIDDLE(ErrorB2) */ LAST(ErrorC)

enum Errors
{
    #define ENUMFIRST_ERROR(E)  E=0,
    #define ENUMMIDDLE_ERROR(E) E,
    #define ENUMLAST_ERROR(E)   E
    VISIT_ERROR(ENUMFIRST_ERROR, ENUMMIDDLE_ERROR, ENUMLAST_ERROR)
    // you might undefine the 3 macros defined above
};

std::string toString(Error e)
{
    switch(e)
    {
    #define CASERETURN_ERROR(E)  case E: return #E;
    VISIT_ERROR(CASERETURN_ERROR, CASERETURN_ERROR, CASERETURN_ERROR)
    // you might undefine the above macro.
    // note that this will produce compile-time error for synonyms in enum;
    // handle those, if you have any, in a distinct macro

    default:
        throw my_favourite_exception();
    }
}

The advantage of this approach is that: - it's still simple to understand, yet - it allows for various visitations (not just string)

If you're willing to drop the first, craft yourself a FOREACH() macro, then #define ERROR_VALUES() (ErrorA, ErrorB, ErrorC) and write your visitors in terms of FOREACH(). Then try to pass a code review :).

The typical way to send binary in json is to base64 encode it.

Java provides different ways to Base64 encode and decode a byte[]. One of these is DatatypeConverter.

Very simply

byte[] originalBytes = new byte[] { 1, 2, 3, 4, 5};
String base64Encoded = DatatypeConverter.printBase64Binary(originalBytes);
byte[] base64Decoded = DatatypeConverter.parseBase64Binary(base64Encoded);

You'll have to make this conversion depending on the json parser/generator library you use.

Simply style your Submit button like you would style any other html element. you can target different type of input elements using CSS attribute selector

As an example you could write

input[type=text] {
   /*your styles here.....*/
}
input[type=submit] {
   /*your styles here.....*/
}
textarea{
   /*your styles here.....*/
}

Combine with other selectors

input[type=text]:hover {
   /*your styles here.....*/
}
input[type=submit] > p {
   /*your styles here.....*/
}
....

Here is a working Example

pass in Python basically does nothing, but unlike a comment it is not ignored by interpreter. So you can take advantage of it in a lot of places by making it a place holder:

1: Can be used in class

class TestClass: 
    pass

2: Can be use in loop and conditional statements:

if (something == true):  # used in conditional statement
    pass
   
while (some condition is true):  # user is not sure about the body of the loop
    pass

3: Can be used in function :

def testFunction(args): # programmer wants to implement the body of the function later
    pass

pass is mostly used when programmer does not want to give implementation at the moment but still wants to create a certain class/function/conditional statement which can be used later on. Since the Python interpreter does not allow for blank or unimplemented class/function/conditional statement it gives an error:

IndentationError: expected an indented block

pass can be used in such scenarios.

Use sudo instead

EDIT: As Douglas pointed out, you can not use cd in sudo since it is not an external command. You have to run the commands in a subshell to make the cd work.

sudo -u $USERNAME -H sh -c "cd ~/$PROJECT; svn update"

sudo -u $USERNAME -H cd ~/$PROJECT
sudo -u $USERNAME svn update

You may be asked to input that user's password, but only once.

Using the Excel Text import wizard to import it if it is a text file, like a CSV file, is another option and can be done based on which row number to which row numbers you specify. See: This link

If it makes sense in your context, you can simply add an empty 12-column div after each break, which acts as a divider that hugs the bottom of the tallest cell in your row.

<div class="row">_x000D_
   <div class="col-xs-6">Some content</div>_x000D_
   <div class="col-xs-6">_x000D_
      Lots of content! Lots of content! Lots of content! Lots of content! Lots of content! _x000D_
   </div>_x000D_
   <div id="spacer-div" class="col-xs-12"></div>_x000D_
   <div class="col-xs-6">More content...</div>_x000D_
</div><!--this You forgot to close -->

Hope this helps!

I tend to use  

It's not pretty but it's the least confusing way to add whitespace I've found and it gives me absolute control over how much whitespace I add.

If I want to add 5 spaces:

Hello&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<span className="second-word-formatting">World!</span>

It's easy to identify exactly what I'm trying to do here when I come back to the code weeks later.

Googled "Permission denied (publickey). fatal: The remote end hung up unexpectedly", first result an exact SO dupe:

GitHub: Permission denied (publickey). fatal: The remote end hung up unexpectedly which links here in the accepted answer (from the original poster, no less): http://help.github.com/linux-set-up-git/

Here is a alternative solution that should survive if the client pc goes into sleep mode.

If you have a huge amount of logged in users then use this cautiously as this could eat a lot of server memory.

After you login (i do this in the LoggedIn event of the login control)

Dim loggedOutAfterInactivity As Integer = 999 'Minutes

'Keep the session alive as long as the authentication cookie.
Session.Timeout = loggedOutAfterInactivity

'Get the authenticationTicket, decrypt and change timeout and create a new one.
Dim formsAuthenticationTicketCookie As HttpCookie = _
        Response.Cookies(FormsAuthentication.FormsCookieName)

Dim ticket As FormsAuthenticationTicket = _
        FormsAuthentication.Decrypt(formsAuthenticationTicketCookie.Value)
Dim newTicket As New FormsAuthenticationTicket(
        ticket.Version, ticket.Name, ticket.IssueDate, 
        ticket.IssueDate.AddMinutes(loggedOutAfterInactivity), 
        ticket.IsPersistent, ticket.UserData)
formsAuthenticationTicketCookie.Value = FormsAuthentication.Encrypt(newTicket)

You can use the isNaN function to determine if a value does not convert to a number. Example as below:

function checkInp()
{
  var x=document.forms["myForm"]["age"].value;
  if (isNaN(x)) 
  {
    alert("Must input numbers");
    return false;
  }
}

You need to open chrome in developper mode : select more tools then extensions and select developper mode

I know this is old, but I recently faced the same issue and I managed to pick the element by accessing only the attribute like this: document.querySelector('[name="your-selector-name-here"]');

Just in case anyone would ever need this :)

or is not exclusive (e.g. xor) so or is the same thing as and/or.

You could use $ extraction:

class(aframe$a1)
[1] "numeric"

or the double square bracket:

class(aframe[["a1"]])
[1] "numeric"

I'm using a custom view that I layout on top of the other ones and that just draws the 4 small corners in the same color as the background. This works whatever the view contents are and does not allocate much memory.

            setColor(a.getColor(R.styleable.RoundedCornersView_cornersColor, Color.WHITE));
        } finally {

        mPaint.setAntiAlias(true);

        invalidate();
    }

    private void setRadius(float radius) {
        mRadius = radius;
        RectF r = new RectF(0, 0, 2 * mRadius, 2 * mRadius);

        mPath.lineTo(0,0);
        invalidate();
    }

I just Improved ProllyGeek`s answer

Someone may find it useful. you can access displayChanged(event, state) event when .show(), .hide() or .toggle() is called on element

(function() {
  var eventDisplay = new $.Event('displayChanged'),
    origShow = $.fn.show,
    origHide = $.fn.hide;
  //
  $.fn.show = function() {
    origShow.apply(this, arguments);
    $(this).trigger(eventDisplay,['show']);
  };
  //
  $.fn.hide = function() {
    origHide.apply(this, arguments);
    $(this).trigger(eventDisplay,['hide']);
  };
  //
})();

$('#header').on('displayChanged', function(e,state) {
      console.log(state);
});

$('#header').toggle(); // .show() .hide() supported

You can achieve this with Collections framework. Put all your options in a Collection say something like Collection<String> options ;

Then loop throgh this to compare your string with the list elements and if it is you can return a boolean value true and otherwise false.

You want to use %p to print a pointer. From the spec:

p The argument shall be a pointer to void. The value of the pointer is converted to a sequence of printing characters, in an implementation-defined manner.

And don't forget the cast, e.g.

printf("%p\n",(void*)&a);

You can use RTRIM or cast your value to VARCHAR:

SELECT RIGHT(RTRIM(Field),3), LEFT(Field,LEN(Field)-3)

Or

SELECT RIGHT(CAST(Field AS VARCHAR(15)),3), LEFT(Field,LEN(Field)-3)

All answers above are awesome

Also add this otherwise your app will crash like mine without any reason

Use this code, but you need to be the admin on the server

public bool CheckMimeMapExtension(string fileExtension)
        {
            try
            {

                using (
                ServerManager serverManager = new ServerManager())
                {   
                    // connects to default app.config
                    var config = serverManager.GetApplicationHostConfiguration();
                    var staticContent = config.GetSection("system.webServer/staticContent");
                    var mimeMap = staticContent.GetCollection();

                    foreach (var mimeType in mimeMap)
                    {

                        if (((String)mimeType["fileExtension"]).Equals(fileExtension, StringComparison.OrdinalIgnoreCase))
                            return true;

                    }

                }
                return false;
            }
            catch (Exception ex)
            { 
                Console.WriteLine("An exception has occurred: \n{0}", ex.Message);
                Console.Read();
            }

            return false;

        }

I would use printf instead of echo because it's more reliable and processes formatting such as new line \n properly.

This example produces an output similar to echo in previous examples:

printf "hello world"  >> read.txt   
cat read.txt
hello world

However if you were to replace printf with echo in this example, echo would treat \n as a string, thus ignoring the intent

printf "hello\nworld"  >> read.txt   
cat read.txt
hello
world

This option is fine for me :

ChromeOptions options = new ChromeOptions();
options.addArguments("start-fullscreen");

This option works on all OS.

This is what I do for Jupyter/Anaconda on Windows. This method also passes jupyter a python configuration script. I use this to add a path to my project parent folder:

1 Create jnote.bat somewhere:

@echo off
call activate %1
call jupyter notebook "%CD%" %2 %3
pause

In the same folder create a windows shortcut jupyter-notebook

        TARGET: D:\util\jnote.bat py3-jupyter --config=jupyter_notebook_config.py
        START IN: %CD%

Add the jupyter icon to the shortcut.

2 In your jupyter projects folders(s) do the following:

Create jupyter_notebook_config.py, put what you like in here:

import os
import sys
import inspect

# Add parent folder to sys path

currentdir = os.path.dirname(os.path.abspath(
    inspect.getfile(inspect.currentframe())))

parentdir = os.path.dirname(currentdir)

os.environ['PYTHONPATH'] = parentdir

Then paste the jupyter-notebook shortcut. Double-click the shortcut and your jupyter should light up and the packages in the parent folder will be available.

1. stop mysql

My guess is that byteArrayIn doesn't contain valid image data.

Please give more information though:

• Which line of code is throwing an exception?
• What's the message?
• Where did you get byteArrayIn from, and are you sure it should contain a valid image?

One of the goals of compilers is to rule out classes of errors. Some unreachable code is there by accident, it's nice that javac rules out that class of error at compile time.

For every rule that catches erroneous code, someone will want the compiler to accept it because they know what they're doing. That's the penalty of compiler checking, and getting the balance right is one of the tricker points of language design. Even with the strictest checking there's still an infinite number of programs that can be written, so things can't be that bad.

Do it like this:

Parentdivimage should have specified width and height, and its position should be:

position: relative;

Just inside the parentdivimage, next to other divs that parent contains you should put:

<a href="linkt.to.smthn.com"><span class="clickable"></span></a>

Then in css file:

.clickable {
  height: 100%;
  width: 100%;
  left: 0;
  top: 0;
  position: absolute;     
  z-index: 1;
}

The span tag will fill out its parent block which is parentdiv, because of height and width set to 100%. Span will be on the top of all of surrounding elements because of setting z-index higher than other elements. Finally span will be clickable, because it's inside of an 'a' tag.

printStackTrace() helps the programmer to understand where the actual problem occurred. printStacktrace() is a method of the class Throwable of java.lang package. It prints several lines in the output console. The first line consists of several strings. It contains the name of the Throwable sub-class & the package information. From second line onwards, it describes the error position/line number beginning with at.

The last line always describes the destination affected by the error/exception. The second last line informs us about the next line in the stack where the control goes after getting transfer from the line number described in the last line. The errors/exceptions represents the output in the form a stack, which were fed into the stack by fillInStackTrace() method of Throwable class, which itself fills in the program control transfer details into the execution stack. The lines starting with at, are nothing but the values of the execution stack. In this way the programmer can understand where in code the actual problem is.

Along with the printStackTrace() method, it's a good idea to use e.getmessage().

you should make a css class .my_style then use .addClass('.mystyle')

First, you declared $db outside the function. If you want to use it inside the function, you should put this at the begining of your function code:

global $db;

And I guess, when you wrote:

if($result->num_rows){
        return (mysqli_result($query, 0) == 1) ? true : false;

what you really wanted was:

if ($result->num_rows==1) { return true; } else { return false; }

There is collection of Func<...> classes - Func that is probably what you are looking for:

 void MyMethod(Func<int> param1 = null) 

This defines method that have parameter param1 with default value null (similar to AS), and a function that returns int. Unlike AS in C# you need to specify type of the function's arguments.

So if you AS usage was

MyMethod(function(intArg, stringArg) { return true; }) 

Than in C# it would require param1 to be of type Func<int, siring, bool> and usage like

MyMethod( (intArg, stringArg) => { return true;} ); 

I'd try something like this.

    try:
            f = open(filePath)
    except IOError:
            print "No such file: %s" % filePath
            raw_input("Press Enter to close window")
    try:
            lines = f.readlines()
            while True:
                    line = f.readline()
                    try:
                            if not line:
                                    time.sleep(1)
                            else:
                                    functionThatAnalisesTheLine(line)
                    except Exception, e:
                            # handle the exception somehow (for example, log the trace) and raise the same exception again
                            raw_input("Press Enter to close window")
                            raise e
    finally:
            f.close()

The loop checks if there is a new line(s) since last time file was read - if there is, it's read and passed to the functionThatAnalisesTheLine function. If not, script waits 1 second and retries the process.

I think somewhere in your codebase are you @Autowiring the concrete class ServiceImpl where you should be autowiring it's interface (presumably MyService).

I had this same problem and it turns out it was because I had the Chrome extension "HTTPS Everywhere" running. Disabling the extension solved my problem.

The ubuntu package name is qt5-default, not qt.

After some testing in Python 3.8+ I noticed that those options give the exact same result, at least in Windows 10.

import time

# Option 1
unix_time_ms_1 = int(time.time_ns() / 1000000)
# Option 2
unix_time_ms_2 = int(time.time() * 1000)

Feel free to use the one you like better and I do not see any need for a more complicated solution then this.

You set DockPanel.Dock="Top" to the StackPanel, but the StackPanel is not a child of the DockPanel... the Border is. Your docking property is being ignored.

If you move DockPanel.Dock="Top" to the Border instead, both of your problems will be fixed :)

You could use a package like org.json http://www.json.org/java/

Because you will need to use JSONObjects more often.

There you can easily create JSONObjects and put some values in it:

 JSONObject json = new JSONObject();
 JSONArray array=new JSONArray();
    array.put("1");
    array.put("2");
    json.put("friends", array);

    System.out.println(json.toString(2));


    {"friends": [
      "1",
      "2"
    ]}

edit This has the advantage that you can build your responses in different layers and return them as an object

Further to @pmg's answer, note that you can do both operations in one statement:

char mystr[] = "Nmy stringP";
char *p = mystr;
p++[strlen(p)-1] = 0;

This will likely work as expected but behavior is undefined in C standard.

Those algorithms are both incorrect because of the comparison:

for( int i = 0; i < elements.length - 1; i++)

or

for(int i = 0; i + 1 < elements.length; i++) {

It's true that the array elements range from 0 to length - 1, but the comparison in that case should be less than or equal to. Those should be:

for(int i = 0; i < elements.length; i++) {

or

for(int i = 0; i <= elements.length - 1; i++) {

or

for(int i = 0; i + 1 <= elements.length; i++) {

The array ["a", "b"] would iterate as:

i = 0 is < 2: elements[0] yields "a"

i = 1 is < 2: elements[1] yields "b"

then exit the loop because 2 is not < 2.

The incorrect examples both exit the loop prematurely and only execute with the first element in this simple case of two elements.

random functions like borland complier

using namespace std;

int sys_random(int min, int max) {
   return (rand() % (max - min+1) + min);
}

void sys_randomize() {
    srand(time(0));
}

You can also check like struct_var == (struct{}). This does not allow you to compare to nil but it does check if it is initialized or not. Be careful while using this method. If your struct can have zero values for all of its fields you won't have great time.

package main

import "fmt"

type A struct {
    Name string
}

func main() {
    a := A{"Hello"}
    var b A

    if a == (A{}) {
        fmt.Println("A is empty") // Does not print
    } 

    if b == (A{}) {
        fmt.Println("B is empty") // Prints
    } 
}

        for (int i = 1; i < numColumns + 1; i++) {
            String column_name = rsmd.getColumnName(i);

            if (rsmd.getColumnType(i) == java.sql.Types.ARRAY) {

                obj.put(column_name, rs.getDouble(column_name));

I would prefer to shelve changes instead of stashing them if I am not sharing my changes elsewhere.

Stashing is a git feature and doesn't give you the option to select specific files or changes inside a file. Shelving can do that but this is an IDE-specific feature, not a git feature:

As you can see I am able to choose to specify which files/lines to include on my shelve. Note that I can't do that with stashing.

Beware using shelves in the IDE may limit the portability of your patches because those changes are not stored in a .git folder.

Some helpful links:

• https://www.jetbrains.com/help/idea/shelving-and-unshelving-changes.html
• https://www.jetbrains.com/help/idea/work-on-several-features-simultaneously.html

Use either a simple blank * or [:blank:]* to remove all possible spaces at the end of the line:

sed 's/ *$//' file

Using the [:blank:] class you are removing spaces and tabs:

sed 's/[[:blank:]]*$//' file

Note this is POSIX, hence compatible in both GNU sed and BSD.

For just GNU sed you can use the GNU extension \s* to match spaces and tabs, as described in BaBL86's answer. See POSIX specifications on Basic Regular Expressions.

Let's test it with a simple file consisting on just lines, two with just spaces and the last one also with tabs:

$ cat -vet file
hello   $
bye   $
ha^I  $     # there is a tab here

Remove just spaces:

$ sed 's/ *$//' file | cat -vet -
hello$
bye$
ha^I$       # tab is still here!

Remove spaces and tabs:

$ sed 's/[[:blank:]]*$//' file | cat -vet -
hello$
bye$
ha$         # tab was removed!

I'm not sure why you'd want to validate an optional email address, but I'd suggest you use

^$|^[^@\s]+@[^@\s]+$

meaning

^$        empty string
|         or
^         beginning of string
[^@\s]+   any character but @ or whitespace
@         
[^@\s]+
$         end of string

You won't stop fake emails anyway, and this way you won't stop valid addresses.

If you are sending HTML email then use <BR> (or <BR />, or </BR>) as stated.
If you are sending a plain text email then use %0D%0A
\r = %0D (Ctrl+M = carriage return)
\n = %0A (Ctrl+A = line feed)

If you have an email link in your email,
EG

<A HREF="mailto?To=...&Body=Line 1%250D%250ALine 2">Send email</A>

Then use %250D%250A

%25 = %

for this simply follow below query

select a.Id,a.type,b.Name,b.City from DatabaseName.dbo.TableName a left join DatabaseName.dbo.TableName b on a.Id=b.Id

Where I wrote databasename, you have to define the name of the database. If you are in same database so you don't need to define the database name but if you are in other database you have to mention database name as path or it will show you error. Hope I made your work easy

(copy-paste/adapted from https://stackoverflow.com/a/24048772/1733117).

First you can subclass urllib2.BaseHandler or urllib2.HTTPBasicAuthHandler, and implement http_request so that each request has the appropriate Authorization header.

import urllib2
import base64

class PreemptiveBasicAuthHandler(urllib2.HTTPBasicAuthHandler):
    '''Preemptive basic auth.

    Instead of waiting for a 403 to then retry with the credentials,
    send the credentials if the url is handled by the password manager.
    Note: please use realm=None when calling add_password.'''
    def http_request(self, req):
        url = req.get_full_url()
        realm = None
        # this is very similar to the code from retry_http_basic_auth()
        # but returns a request object.
        user, pw = self.passwd.find_user_password(realm, url)
        if pw:
            raw = "%s:%s" % (user, pw)
            auth = 'Basic %s' % base64.b64encode(raw).strip()
            req.add_unredirected_header(self.auth_header, auth)
        return req

    https_request = http_request

Then if you are lazy like me, install the handler globally

api_url = "http://api.foursquare.com/"
api_username = "johndoe"
api_password = "some-cryptic-value"

auth_handler = PreemptiveBasicAuthHandler()
auth_handler.add_password(
    realm=None, # default realm.
    uri=api_url,
    user=api_username,
    passwd=api_password)
opener = urllib2.build_opener(auth_handler)
urllib2.install_opener(opener)

In C++11, lambda functions can not be templated, but in the next version of the ISO C++ Standard (often called C++14), this feature will be introduced. [Source]

Usage example:

auto get_container_size = [] (auto container) { return container.size(); };

Note that though the syntax uses the keyword auto, the type deduction will not use the rules of auto type deduction, but instead use the rules of template argument deduction. Also see the proposal for generic lambda expressions(and the update to this).

Try putting the search condition in a bracket, as shown below. This returns the result of the conditional query inside the bracket. Then test its result to determine if it is negative (i.e. it does not belong to any of the options in the vector), by setting it to FALSE.

SE_CSVLinelist_filtered <- filter(SE_CSVLinelist_clean, 
(where_case_travelled_1 %in% c('Outside Canada','Outside province/territory of residence but within Canada')) == FALSE)

there are some mistakes in your code - the first: you havn't closed you p-tag:

<a href="http//www.google.com"><p style="text-align:center">Search</p></a>

next: p stands for 'paragraph' and is a block-element (so it's causing a line-break). what you wanted to use there is a span, wich is just an inline-element for formatting:

<a href="http//www.google.com"><span style="text-align:center">Search</span></a>

but if you just want to add a style to your link, why don't you set the style for that link directly:

<a href="http//www.google.com" style="text-align:center">Search</a>

in the end, this would at least be correct html, but still not exactly what you want, because text-align:center centers the text in that element, so you would have to set that for the element that contains this links (this piece of html isn't posted, so i can't correct you, but i hope you understand) - to show this, i'll use a simple div:

<div style="text-align:center">    
  <a href="http//www.google.com">Search</a>
  <!-- more links here -->
</div>

EDIT: some more additions to your question:

• p is not a 'function', but you're right, this is causing the problem (because it's a block-element)
• what you're trying to use is css - it's just inline instead of being placed in a seperate file, but you aren't doing 'just HTML' here

Your client should hire someone that knows what they are doing, who can make the right decisions and can mentor you.

Talk above about you having some ability to change the transaction processing system on the backend is absurd - you shouldn't be allowed to make such architectural changes, so don't expect to be able to.

My rationale on this:

Since your domain is payment processing, its safe to assume that PCI DSS and/or PA DSS (and potential state/federal law) will be significant to your business - to be compliant you must show you are secure. To be insecure then find out (via testing) that you aren't secure, then fixing, retesting, etcetera until security can be verified at a suitable level = expensive, slow, high-risk way to success. To do the right thing, think hard up front, commit experienced talent to the job, develop in a secure manner, then test, fix (less), etcetera (less) until security can be verified at a suitable level = inexpensive, fast, low-risk way to success.

Or use box-shadow if table have collapse

Since no-one has yet wrote a function to do this with two integers, here's one way:

private long CalculatePower(int number, int powerOf)
{
    for (int i = powerOf; i > 1; i--)
        number *= number;
    return number;
}
CalculatePower(5, 3); // 125
CalculatePower(8, 4); // 4096
CalculatePower(6, 2); // 36

Alternatively in VB.NET:

Private Function CalculatePower(number As Integer, powerOf As Integer) As Long
    For i As Integer = powerOf To 2 Step -1
        number *= number
    Next
    Return number
End Function
CalculatePower(5, 3) ' 125
CalculatePower(8, 4) ' 4096
CalculatePower(6, 2) ' 36

To install Python package from github, you need to clone that repository.

git clone https://github.com/jkbr/httpie.git

Then just run the setup.py file from that directory,

sudo python setup.py install

There are only two syntaxes at play here.

1. Plain old array initialisation:

   int x[] = {0, 0}; // x[0] = 0, x[1] = 0
   

2. A designated initialiser. See the accepted answer to this question: How to initialize a struct in accordance with C programming language standards

   The syntax is pretty self-explanatory though. You can initialise like this:

   struct X {
       int a;
       int b;
   }
   struct X foo = { 0, 1 }; // a = 0, b = 1
   

   or to use any ordering,

   struct X foo = { .b = 0, .a = 1 }; // a = 1, b = 0
   

My experience with larger files sizes has been that java.nio is faster than java.io. Solidly faster. Like in the >250% range. That said, I am eliminating obvious bottlenecks, which I suggest your micro-benchmark might suffer from. Potential areas for investigating:

The buffer size. The algorithm you basically have is

• copy from disk to buffer
• copy from buffer to disk

My own experience has been that this buffer size is ripe for tuning. I've settled on 4KB for one part of my application, 256KB for another. I suspect your code is suffering with such a large buffer. Run some benchmarks with buffers of 1KB, 2KB, 4KB, 8KB, 16KB, 32KB and 64KB to prove it to yourself.

Don't perform java benchmarks that read and write to the same disk.

If you do, then you are really benchmarking the disk, and not Java. I would also suggest that if your CPU is not busy, then you are probably experiencing some other bottleneck.

Don't use a buffer if you don't need to.

Why copy to memory if your target is another disk or a NIC? With larger files, the latency incured is non-trivial.

Like other have said, use FileChannel.transferTo() or FileChannel.transferFrom(). The key advantage here is that the JVM uses the OS's access to DMA (Direct Memory Access), if present. (This is implementation dependent, but modern Sun and IBM versions on general purpose CPUs are good to go.) What happens is the data goes straight to/from disc, to the bus, and then to the destination... bypassing any circuit through RAM or the CPU.

The web app I spent my days and night working on is very IO heavy. I've done micro benchmarks and real-world benchmarks too. And the results are up on my blog, have a look-see:

• Real world performance metrics: java.io vs. java.nio
• Real world performance metrics: java.io vs. java.nio (The Sequel)

Use production data and environments

Micro-benchmarks are prone to distortion. If you can, make the effort to gather data from exactly what you plan to do, with the load you expect, on the hardware you expect.

My benchmarks are solid and reliable because they took place on a production system, a beefy system, a system under load, gathered in logs. Not my notebook's 7200 RPM 2.5" SATA drive while I watched intensely as the JVM work my hard disc.

What are you running on? It matters.

@Html.TextArea("txtNotes", "", 4, 0, new { @class = "k-textbox", style = "width: 100%; height: 100%;" })

In kotlin just use activity instead of getActivity()

Except first answer form Bathsheba, except MSDN information for:

.Value
.Value2
.Text

you could analyse these tables for better understanding of differences between analysed properties.

Make resource controller with Model.

php artisan make:controller PostController --model=Post

I think you should use git pull --rebase when collaborating with others on the same branch. You are in your work ? commit ? work ? commit cycle, and when you decide to push your work your push is rejected, because there's been parallel work on the same branch. At this point I always do a pull --rebase. I do not use squash (to flatten commits), but I rebase to avoid the extra merge commits.

As your Git knowledge increases you find yourself looking a lot more at history than with any other version control systems I've used. If you have a ton of small merge commits, it's easy to lose focus of the bigger picture that's happening in your history.

This is actually the only time I do rebasing(*), and the rest of my workflow is merge based. But as long as your most frequent committers do this, history looks a whole lot better in the end.

(*) While teaching a Git course, I had a student arrest me on this, since I also advocated rebasing feature branches in certain circumstances. And he had read this answer ;) Such rebasing is also possible, but it always has to be according to a pre-arranged/agreed system, and as such should not "always" be applied. And at that time I usually don't do pull --rebase either, which is what the question is about ;)

I think this is exactly what you were looking for

http://today.java.net/pub/a/today/2007/06/26/generating-pdfs-with-flying-saucer-and-itext.html

http://code.google.com/p/flying-saucer

Flying Saucer's primary purpose is to render spec-compliant XHTML and CSS 2.1 to the screen as a Swing component. Though it was originally intended for embedding markup into desktop applications (things like the iTunes Music Store), Flying Saucer has been extended work with iText as well. This makes it very easy to render XHTML to PDFs, as well as to images and to the screen. Flying Saucer requires Java 1.4 or higher.

Try putting

Display:inline;

In the CSS.

Old string, but maybe my answer will help somebody.

First get your SqlDataSource as a DataView:

Private Sub DataGrid1_SortCommand(ByVal source As Object, ByVal e As DataGridSortCommandEventArgs) Handles grid1.SortCommand
    Dim dataView As DataView = CType(SqlDataSource1.Select(DataSourceSelectArguments.Empty), DataView)
    dataView.Sort = e.SortExpression + dataView.FieldSortDirection(Session, e.SortExpression)

    grid1.DataSourceID = Nothing
    grid1.DataSource = dataView
    grid1.DataBind()

End Sub

Then use an extension method for the sort (kind of a cheep shot, but a good start):

public static class DataViewExtensions
{
    public static string FieldSortDirection(this DataView dataView, HttpSessionState session, string sortExpression)
    {
        const string SORT_DIRECTION = "SortDirection";
        var identifier = SORT_DIRECTION + sortExpression;

        if (session[identifier] != null)
        {
            if ((string) session[identifier] == " ASC")
                session[identifier] = " DESC";
            else if ((string) session[identifier] == " DESC")
                session[identifier] = " ASC";
        }
        else
            session[identifier] = " ASC";

        return (string) session[identifier];
    }
}

Simple easy solution for beginners. I have tried many ways and stopped with Genymotion in combination with Eclipse. Genymotion simply adds a virtual device to Eclipse.

Step by step:

1. Download Genymotion with VirtualBox included from here.
2. Install this package included build in VirtualBox.
3. Install the plugin into Eclipse from here.
4. Start GenyMotion and create a virtual device you want use, and start it.
5. In Eclipse, go to Window -> Preferences -> GenyMobile -> GenyMotion, and set the path to GenyMotion (in my case, C:/ProgramFiles/GenyMobile/Genymotion).
6. Click on a project name in Eclipse that you want to start. Start the application using "Run as". In the list of devices, you should see the emulated device.
7. You cam emulate what you want.

In my case, this solution is the one and only fast solution. No emulators in Eclipse have never worked so fast, and every setting was very slow. Only this solution works almost in realtime. I can recommend (notebook i3, 2.6 GHz).

Both are DBMS's Product Sql server is an commercial application while MySql is an opensouces application.Both the product include similar feature,however sql server should be used for an enterprise solution ,while mysql might suit a smaller implementation.if you need feature like recovery,replication,granalar security and significant,you need sql server

MySql takes up less spaces on disk, and uses less memory and cpu than does sql server

Motivation: User would like to Retrieve aws instance metadata.

Solution: The IP address 169.254.169.254 is a link-local address (and is valid only from the instance) aws gives us link with dedicated Restful API for Retrieving metadata of our running instance (Note that you are not billed for HTTP requests used to retrieve instance metadata and user data) . for Additional Documentation

Example:

//Request:
curl http://169.254.169.254/latest/meta-data/instance-id

//Response
ami-123abc

You able to get additional metadata labels of your instance using this link http://169.254.169.254/latest/meta-data/<metadata-field> just choose the right tags:

1. ami-id
2. ami-launch-index
3. ami-manifest-path
4. block-device
5. mapping
6. events
7. hibernation
8. hostname
9. iam
10. identity-credentials
11. instance-action
12. instance-id
13. instance-type
14. local-hostname
15. local-ipv4
16. mac
17. metrics
18. network
19. placement
20. profile
21. reservation-id
22. security-groups
23. services

None of the above mentioned solution worked for me due to some reason. Here is my solution. It's pretty basic.

curl -X GET API_ENDPOINT -H 'Content-Type: application/json' -d 'JSON_DATA'

API_ENDPOINT is your api endpoint e.g: http://127.0.0.1:80/api

-H has been used to added header content.

JSON_DATA is your request body it can be something like :: {"data_key": "value"} . ' ' surrounding JSON_DATA are important.

Anything after -d is the data which you need to send in the GET request

Add tomcat in Eclipse

In Eclipse, as tomcat server, double click "Tomcat v7.0 Server at Localhost", Change the properties as shown in time out settings 45 to whatever sec you like

create a divider class as follows:

.divider{
    width:5px;
    height:auto;
    display:inline-block;
}

Then attach this to a div between the two buttons

<div style="text-align: center"> 
    <asp:Button ID="btnSubmit" runat="server" Text="Submit" Width="89px" OnClick="btnSubmit_Click" />
    <div class="divider"/>
    <asp:Button ID="btnClear" runat="server" Text="Clear" Width="89px" OnClick="btnClear_Click" />
</div>

This is the best way as it avoids the box model, which can be a pain on older browsers, and doesn't add any extra characters that would be picked up by a screen reader, so it is better for readability.

It's good to have a number of these types of divs for certain scenarios (my most used one is vert5spacer, similar to this but puts a block div with height 5 and width auto for spacing out items in a form etc.

Assuming the column is set to support NULL as a value:

UPDATE YOUR_TABLE
   SET column = NULL

Be aware of the database NULL handling - by default in SQL Server, NULL is an INT. So if the column is a different data type you need to CAST/CONVERT NULL to the proper data type:

UPDATE YOUR_TABLE
   SET column = CAST(NULL AS DATETIME)

...assuming column is a DATETIME data type in the example above.

I know this is really old post but here is a simple solution to work with dynamic type in c#.

1. can use simple reflection to enumerate direct properties
2. or can use the object extention method
3. or use GetAsOrDefault<int> method to get a new strongly typed object with value if exists or default if not exists.

public static class DynamicHelper
{
    private static void Test( )
    {

                        {
                            myInt = 1,
                            myArray = new[ ]
                                      {
                                          1, 2.3
                                      },
                            myDict = new
                                     {
                                         myInt = 1
                                     }

I think the best way to reach your div:

var your_element=$('iframe#uploads').children('iframe').children('div#element');

It should work well.

if anybody unable to update windows online, I suggest you go to http://download.wsusoffline.net/ and download Most recent version.

Then install update generator -> select your operating system. and hit START, just wait few minutes let him download updates and complete all it's process. hope this help.

The hacky, practical answer for people trying to evaluate which Heroku plan they need and can't wait for heroku's slow row counter to refresh:

Basically you want to run \dt in psql, copy the results to your favorite text editor (it will look like this:

 public | auth_group                     | table | axrsosvelhutvw
 public | auth_group_permissions         | table | axrsosvelhutvw
 public | auth_permission                | table | axrsosvelhutvw
 public | auth_user                      | table | axrsosvelhutvw
 public | auth_user_groups               | table | axrsosvelhutvw
 public | auth_user_user_permissions     | table | axrsosvelhutvw
 public | background_task                | table | axrsosvelhutvw
 public | django_admin_log               | table | axrsosvelhutvw
 public | django_content_type            | table | axrsosvelhutvw
 public | django_migrations              | table | axrsosvelhutvw
 public | django_session                 | table | axrsosvelhutvw
 public | exercises_assignment           | table | axrsosvelhutvw

), then run a regex search and replace like this:

^[^|]*\|\s+([^|]*?)\s+\| table \|.*$

to:

select '\1', count(*) from \1 union/g

which will yield you something very similar to this:

select 'auth_group', count(*) from auth_group union
select 'auth_group_permissions', count(*) from auth_group_permissions union
select 'auth_permission', count(*) from auth_permission union
select 'auth_user', count(*) from auth_user union
select 'auth_user_groups', count(*) from auth_user_groups union
select 'auth_user_user_permissions', count(*) from auth_user_user_permissions union
select 'background_task', count(*) from background_task union
select 'django_admin_log', count(*) from django_admin_log union
select 'django_content_type', count(*) from django_content_type union
select 'django_migrations', count(*) from django_migrations union
select 'django_session', count(*) from django_session
;

(You'll need to remove the last union and add the semicolon at the end manually)

Run it in psql and you're done.

            ?column?            | count
--------------------------------+-------
 auth_group_permissions         |     0
 auth_user_user_permissions     |     0
 django_session                 |  1306
 django_content_type            |    17
 auth_user_groups               |   162
 django_admin_log               |  9106
 django_migrations              |    19

$('#select-meal-type').change(function(){

No need to use a macro. Supposing your first string is in A1.

=RIGHT(A1, 4)

Drag this down and you will get your four last characters.

Edit: To be sure, if you ever have sequences like 'ABC DEF' and want the last four LETTERS and not CHARACTERS you might want to use trimspaces()

=RIGHT(TRIMSPACES(A1), 4)

Edit: As per brettdj's suggestion, you may want to check that your string is actually 4-character long or more:

=IF(TRIMSPACES(A1)>=4, RIGHT(TRIMSPACES(A1), 4), TRIMSPACES(A1))

Your code would be like this:

int *p = (int *)0x28ff44;

int needs to be the type of the object that you are referencing or it can be void.

But be careful so that you don't try to access something that doesn't belong to your program.

I've tried all the previous answers and found the answer on MSDN after none of these worked for me. See 'UserName4' for the correct one for me.

I'm after the Logged in User, as displayed by:

<asp:LoginName ID="LoginName1" runat="server" />

Here's a little function I wrote to try them all. My result is in the comments after each row.

protected string GetLoggedInUsername()
{
    string UserName = System.Security.Principal.WindowsIdentity.GetCurrent().Name; // Gives NT AUTHORITY\SYSTEM
    String UserName2 = Request.LogonUserIdentity.Name; // Gives NT AUTHORITY\SYSTEM
    String UserName3 = Environment.UserName; // Gives SYSTEM
    string UserName4 = HttpContext.Current.User.Identity.Name; // Gives actual user logged on (as seen in <ASP:Login />)
    string UserName5 = System.Windows.Forms.SystemInformation.UserName; // Gives SYSTEM
    return UserName4;
}

Calling this function returns the logged in username by return.

Update: I would like to point out that running this code on my Local server instance shows me that Username4 returns "" (an empty string), but UserName3 and UserName5 return the logged in User. Just something to beware of.

Swift 3/4/5 Solution

Select Row

let indexPath = IndexPath(row: 0, section: 0)
tblView.selectRow(at: indexPath, animated: true, scrollPosition: .bottom)
myTableView.delegate?.tableView!(myTableView, didSelectRowAt: indexPath)

DeSelect Row

let deselectIndexPath = IndexPath(row: 7, section: 0)
tblView.deselectRow(at: deselectIndexPath, animated: true)
tblView.delegate?.tableView!(tblView, didDeselectRowAt: indexPath)

Here my solution (Spring 2.0.x)

Add the maven dependency:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

Edit the application.properties and add the following line:

management.endpoints.web.exposure.include=* 

Once your spring boot application is started you can track the latest 100 http requests by calling this url: http://localhost:8070/actuator/httptrace

Here is the an other way. if you don't like exceptions.

def strnumber = "100"
def intValue = strnumber.isInteger() ?  (strnumber as int) : null

Simple Steps, follow them and i guess it will solve your problem

Include these Css in your page,

.progress {
      position: relative;
      height: 2px;
      display: block;
      width: 100%;
      background-color: white;
      border-radius: 2px;
      background-clip: padding-box;
      /*margin: 0.5rem 0 1rem 0;*/
      overflow: hidden;

    }
    .progress .indeterminate {
background-color:black; }
    .progress .indeterminate:before {
      content: '';
      position: absolute;
      background-color: #2C67B1;
      top: 0;
      left: 0;
      bottom: 0;
      will-change: left, right;
      -webkit-animation: indeterminate 2.1s cubic-bezier(0.65, 0.815, 0.735, 0.395) infinite;
              animation: indeterminate 2.1s cubic-bezier(0.65, 0.815, 0.735, 0.395) infinite; }
    .progress .indeterminate:after {
      content: '';
      position: absolute;
      background-color: #2C67B1;
      top: 0;
      left: 0;
      bottom: 0;
      will-change: left, right;
      -webkit-animation: indeterminate-short 2.1s cubic-bezier(0.165, 0.84, 0.44, 1) infinite;
              animation: indeterminate-short 2.1s cubic-bezier(0.165, 0.84, 0.44, 1) infinite;
      -webkit-animation-delay: 1.15s;
              animation-delay: 1.15s; }

    @-webkit-keyframes indeterminate {
      0% {
        left: -35%;
        right: 100%; }
      60% {
        left: 100%;
        right: -90%; }
      100% {
        left: 100%;
        right: -90%; } }
    @keyframes indeterminate {
      0% {
        left: -35%;
        right: 100%; }
      60% {
        left: 100%;
        right: -90%; }
      100% {
        left: 100%;
        right: -90%; } }
    @-webkit-keyframes indeterminate-short {
      0% {
        left: -200%;
        right: 100%; }
      60% {
        left: 107%;
        right: -8%; }
      100% {
        left: 107%;
        right: -8%; } }
    @keyframes indeterminate-short {
      0% {
        left: -200%;
        right: 100%; }
      60% {
        left: 107%;
        right: -8%; }
      100% {
        left: 107%;
        right: -8%; } }

Then include the progress bar your body tag,

<div class="progress" id="PreLoaderBar">
        <div class="indeterminate"></div>
    </div>

then it will start as your page loads, and now what you have to do is just hide this when the page loads,or set the visibility to none, or hidden, using javascript,

document.onreadystatechange = function () {
            if (document.readyState === "complete") {
                console.log(document.readyState);
                document.getElementById("PreLoaderBar").style.display = "none";
            }
        }

Let me Know if you face any problems and also, you can add any type of progress bar you can easily find them, for this example i have used a indeterminate progress bar.

I tried to implement the result of Nick which is:

$('.selectorUsedToCreateTheDialog').dialog('option', 'title', 'My New title');

But that didn't work for me because i had multiple dialogs on 1 page. In such a situation it will only set the title correct the first time. Trying to staple commands did not work:

    $("#modal_popup").html(data);
    $("#modal_popup").dialog('option', 'title', 'My New Title');
    $("#modal_popup").dialog({ width: 950, height: 550);

I fixed this by adding the title to the javascript function arguments of each dialog on the page:

function show_popup1() {
    $("#modal_popup").html(data);
    $("#modal_popup").dialog({ width: 950, height: 550, title: 'Popup Title of my First Dialog'});
}

function show_popup2() {
    $("#modal_popup").html(data);
    $("#modal_popup").dialog({ width: 950, height: 550, title: 'Popup Title of my Other Dialog'});
}

You can also use ddms for logcat logs where just giving search of the app name you will all info but you have to select Info instead of verbose or other options. check this below image.

You will not able to test the app using the Google-Play-Service library in emulator. In order to test that app in emulator you need to install some system framework in your emulator to make it work.

https://stackoverflow.com/a/11213598/1405008

Refer the above answer to install Google play service on your emulator.

You can now (as of Webpack v5.0.0) specify a unique output path for each entry using the new "descriptor" syntax (https://webpack.js.org/configuration/entry-context/#entry-descriptor) –

module.exports = {
  entry: {
    home: { import: './home.js', filename: 'unique/path/1/[name][ext]' },
    about: { import: './about.js', filename: 'unique/path/2/[name][ext]' }
  }
};

I had successfully used the following on Arch Linux (where the -a flag is used for attachments) for several years:

mailx -s "The Subject $( echo -e "\nContent-Type: text/html" [email protected] < email.html

This appended the Content-Type header to the subject header, which worked great until a recent update. Now the new line is filtered out of the -s subject. Presumably, this was done to improve security.

Instead of relying on hacking the subject line, I now use a bash subshell:

(
    echo -e "Content-Type: text/html\n"
    cat mail.html
 ) | mail -s "The Subject" -t [email protected]

And since we are really only using mailx's subject flag, it seems there is no reason not to switch to sendmail as suggested by @dogbane:

(
    echo "To: [email protected]"
    echo "Subject: The Subject"
    echo "Content-Type: text/html"
    echo
    cat mail.html
) | sendmail -t

The use of bash subshells avoids having to create a temporary file.

table { 
    table-layout:fixed; width:200px;
}
table tr {
    height: 20px;
}

10x10

Although I am very late to answer this, please have a look at the code.

let floatValue = 3.267848;
let decimalDigits = floatValue.toString().split('.')[1];
let decimalPlaces = decimalDigits.length;
let decimalDivider = Math.pow(10, decimalPlaces);
let fractionValue = decimalDigits/decimalDivider;
let integerValue = floatValue - fractionValue;

console.log("Float value: "+floatValue);
console.log("Integer value: "+integerValue);
console.log("Fraction value: "+fractionValue)

None of the existing solutions worked, so I quickly hacked together a script that would do the job. Also converts empty strings into nulls and and separates the header row for JSON. May need to be tuned depending on the CSV dialect and charset you have.

#!/usr/bin/python
import csv, json
csvreader = csv.reader(open('data.csv', 'rb'), delimiter='\t', quotechar='"')
data = []
for row in csvreader:
    r = []
    for field in row:
        if field == '': field = None
        else: field = unicode(field, 'ISO-8859-1')
        r.append(field)
    data.append(r)
jsonStruct = {
    'header': data[0],
    'data': data[1:]
}
open('data.json', 'wb').write(json.dumps(jsonStruct))

You can execute any shell command using the shelljs module

 const shell = require('shelljs')

 shell.exec('./path_to_your_file')

localStorage.clear();

or

window.localStorage.clear();

to clear particular item

window.localStorage.removeItem("item_name");

To remove particular value by id :

var item_detail = JSON.parse(localStorage.getItem("key_name")) || [];           
            $.each(item_detail, function(index, obj){
                if (key_id == data('key')) {
                    item_detail.splice(index,1);
                    localStorage["key_name"] = JSON.stringify(item_detail);
                    return false;
                }
            });

Since the string is not complex, no need to add RegEx strings. A simple match will do the trick

$line = "----start----Hello World----end----"
$line -match "Hello World"
$matches[0]
Hello World

$result = $matches[0]
$result
Hello World

Have you tried?

var isoDateTimeFormat = CultureInfo.InvariantCulture.DateTimeFormat;

// "2013-10-10T22:10:00"
 dateValue.ToString(isoDateTimeFormat.SortableDateTimePattern); 

// "2013-10-10 22:10:00Z"    
dateValue.ToString(isoDateTimeFormat.UniversalSortableDateTimePattern)

Also try using parameters when you store the c# datetime value in the mySql database, this might help.

Well, it's this my DRY installation:

1. Look into a computer with already installed gems needed in the cache directory (by default: [Ruby Installation version]/lib/ruby/gems/[Ruby version]/cache)
2. Copy all "*.gems files" to a computer without gems in own gem cache place (by default the same patron path of first step: [Ruby Installation version]/lib/ruby/gems/[Ruby version]/cache)
3. In the console be located in the gems cache (cd [Ruby Installation version]/lib/ruby/gems/[Ruby version]/cache) and fire the gem install anygemwithdependencieshere (by example cucumber-2.99.0)

It's DRY because after install any gem, by default rubygems put the gem file in the cache gem directory and not make sense duplicate thats files, it's more easy if you want both computer has the same versions (or bloqued by paranoic security rules :v)

Edit: In some versions of ruby or rubygems, it don't work and fire alerts or error, you can put gems in other place but not get DRY, other alternative is using launch integrated command gem server and add the localhost url in gem sources, more information in: https://guides.rubygems.org/run-your-own-gem-server/

I was trying to solve my issue with some of the answers above and for some reason it didn't work. I did switch to use the git extensions and this are the steps I did follow.

1. I went to Tools -> Settings -> SSH -> Other ssh client
2. Set this value to C:\Program Files\Git\usr\bin\ssh.exe
3. Apply

I guess that this steps are just the same explained above. The only difference is that I used the Git Extensions User Interface instead of the terminal. Hope this help.

One could also consider:

def foo():
    try:
        foo.counter += 1
    except AttributeError:
        foo.counter = 1

Reasoning:

• much pythonic ("ask for forgiveness not permission")
• use exception (thrown only once) instead of if branch (think StopIteration exception)

remove partition by and add group by clause,

SELECT BrandId
      ,SUM(ICount) totalSum
  FROM Table 
WHERE DateId  = 20130618
GROUP BY BrandId

Assume the new file is "/home/satya/app/app_specific_env" and the file contents are as follows

#!bin/bash

export FAV_NUMBER="2211"

Append this file reference to ~/.bashrc file

source /home/satya/app/app_specific_env

When ever you restart the machine or relogin, try echo $FAV_NUMBER in the terminal. It will output the value.

Just in case if you want to see the effect right away, source ~/.bashrc in the command line.

I liked Peter Mortenson's answer, but I would like to expand.

'cd ~' in the .bashrc file causes the "Git Bash Here" feature of Git Bash to stop working. Instead, add this if statement to the .bashrc file:

if [ "$PWD" == '/' ]
then
        cd ~
fi

This will change to the home directory when Git Bash is run on its own, but when "Git Bash Here" is run, the current working directory will not be changed.

Open the VBA Editor of Excel and type this in the Immediate Window (See Screenshot)

Application.AskToUpdateLinks = False 

Close Excel and then open your File. It will not prompt you again. Remember to reset it when you close the workbook else it will not work for other workbooks as well.

ScreenShot:

EDIT

So applying it to your code, your code will look like this

Function getWorkbook(bkPath As String) As Workbook
    Application.AskToUpdateLinks = False
    Set getWorkbook = Workbooks.Open(bkPath, False)
    Application.AskToUpdateLinks = True
End Function

FOLLOWUP

Sigil, The code below works on files with broken links as well. Here is my test code.

Test Conditions

1. Create 2 new files. Name them Sample1.xlsx and Sample2.xlsx and save them on C:\
2. In cell A1 of Sample1.xlsx, type this formula ='C:\[Sample2.xlsx]Sheet1'!$A$1
3. Save and close both the files
4. Delete Sample2.xlsx!!!
5. Open a New workbook and it's module paste this code and run Sample. You will notice that you will not get a prompt.

Code

Option Explicit

Sub Sample()
    getWorkbook "c:\Sample1.xlsx"
End Sub

Function getWorkbook(bkPath As String) As Workbook
    Application.AskToUpdateLinks = False
    Set getWorkbook = Workbooks.Open(bkPath, False)
    Application.AskToUpdateLinks = True
End Function

You can choose:

if [[ $? -ne 0 ]]; then       # -ne: not equal

if ! [[ $? -eq 0 ]]; then     # -eq: equal

if [[ ! $? -eq 0 ]]; then

! inverts the return of the following expression, respectively.

Simple way to initiate the message on startup:

bot.on('ready', () => {
    bot.user.setStatus('available')
    bot.user.setPresence({
        game: {
            name: 'with depression',
            type: "STREAMING",
            url: "https://www.twitch.tv/monstercat"
        }
    });
});

You can also just declare it elsewhere after startup, to change the message as needed:

bot.user.setPresence({ game: { name: 'with depression', type: "streaming", url: "https://www.twitch.tv/monstercat"}}); 

In my case (the same problem) helped to add -NoProfile in task action command arguments and check checkbox "Run with highest privileges", because on my server UAC is on (active).

More info about it enter link description here

I assume you know how to get the DOM object for the <a> element (use document.getElementById or some other method).

To add any attribute, just use the setAttribute method on the DOM object:

a = document.getElementById(...);
a.setAttribute("href", "somelink url");

clients.get will return a ClientThread and not a String, and it will bomb with an IndexOutOfBoundsException if it would compile as Java is zero based for indexing.

Similarly I think you should call remove on the clients list.

ClientThread hey = clients.get(clients.size()-1);
clients.remove(hey);
System.out.println(hey + " has logged out.");
System.out.println("CONNECTED PLAYERS: " + clients.size());

I would use the stack functions of a LinkedList in this case though.

ClientThread hey = clients.removeLast()

 import java.util.Date;
 import java.text.SimpleDateFormat;

Above is the import method, below is the simple code for Date

 SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
 Date date = new Date();

 system.out.println((dateFormat.format(date))); 

I just want to add what worked for me, I added height and width to both divs and used bootstrap to make it responsive

   <div class="col-lg-1 mapContainer">
       <div id="map"></div>
   </div>

   #map{
        height: 100%;
        width:100%;
   }
   .mapContainer{
        height:200px;
        width:100%
   }

in order for col-lg-1 to work add bootstrap reference located Here

"Update-Package –reinstall Microsoft.AspNet.WebPages"

Reinstall Microsoft.AspNet.WebPages nuget packages using this command in the package manager console. 100% work!!

So you are asking for ArgMin or ArgMax. C# doesn't have a built-in API for those.

I've been looking for a clean and efficient (O(n) in time) way to do this. And I think I found one:

The general form of this pattern is:

var min = data.Select(x => (key(x), x)).Min().Item2;
                            ^           ^       ^
              the sorting key           |       take the associated original item
                                Min by key(.)

Specially, using the example in original question:

For C# 7.0 and above that supports value tuple:

var youngest = people.Select(p => (p.DateOfBirth, p)).Min().Item2;

For C# version before 7.0, anonymous type can be used instead:

var youngest = people.Select(p => new {age = p.DateOfBirth, ppl = p}).Min().ppl;

They work because both value tuple and anonymous type have sensible default comparers: for (x1, y1) and (x2, y2), it first compares x1 vs x2, then y1 vs y2. That's why the built-in .Min can be used on those types.

And since both anonymous type and value tuple are value types, they should be both very efficient.

NOTE

In my above ArgMin implementations I assumed DateOfBirth to take type DateTime for simplicity and clarity. The original question asks to exclude those entries with null DateOfBirth field:

Null DateOfBirth values are set to DateTime.MaxValue in order to rule them out of the Min consideration (assuming at least one has a specified DOB).

It can be achieved with a pre-filtering

people.Where(p => p.DateOfBirth.HasValue)

So it's immaterial to the question of implementing ArgMin or ArgMax.

NOTE 2

The above approach has a caveat that when there are two instances that have the same min value, then the Min() implementation will try to compare the instances as a tie-breaker. However, if the class of the instances does not implement IComparable, then a runtime error will be thrown:

At least one object must implement IComparable

Luckily, this can still be fixed rather cleanly. The idea is to associate a distanct "ID" with each entry that serves as the unambiguous tie-breaker. We can use an incremental ID for each entry. Still using the people age as example:

var youngest = Enumerable.Range(0, int.MaxValue)
               .Zip(people, (idx, ppl) => (ppl.DateOfBirth, idx, ppl)).Min().Item3;

Nope, you have to open a browser atleast once to create your username on GitHub, once created, you can leverage GitHub API to create repositories from command line, following below command:

curl -u 'github-username' https://api.github.com/user/repos -d '{"name":"repo-name"}'

For example:

curl -u 'arpitaggarwal' https://api.github.com/user/repos -d '{"name":"command-line-repo"}'

Please remove /bin and even semi colon ; from JAVA_HOME to resolve.

1. Why is this happening?

   The entire ext/mysql PHP extension, which provides all functions named with the prefix mysql_, was officially deprecated in PHP v5.5.0 and removed in PHP v7.

   It was originally introduced in PHP v2.0 (November 1997) for MySQL v3.20, and no new features have been added since 2006. Coupled with the lack of new features are difficulties in maintaining such old code amidst complex security vulnerabilities.

   The manual has contained warnings against its use in new code since June 2011.

2. How can I fix it?

   As the error message suggests, there are two other MySQL extensions that you can consider: MySQLi and PDO_MySQL, either of which can be used instead of ext/mysql. Both have been in PHP core since v5.0, so if you're using a version that is throwing these deprecation errors then you can almost certainly just start using them right away—i.e. without any installation effort.

   They differ slightly, but offer a number of advantages over the old extension including API support for transactions, stored procedures and prepared statements (thereby providing the best way to defeat SQL injection attacks). PHP developer Ulf Wendel has written a thorough comparison of the features.

   Hashphp.org has an excellent tutorial on migrating from ext/mysql to PDO.

3. I understand that it's possible to suppress deprecation errors by setting error_reporting in php.ini to exclude E_DEPRECATED:

   error_reporting = E_ALL ^ E_DEPRECATED
   

   What will happen if I do that?

   Yes, it is possible to suppress such error messages and continue using the old ext/mysql extension for the time being. But you really shouldn't do this—this is a final warning from the developers that the extension may not be bundled with future versions of PHP (indeed, as already mentioned, it has been removed from PHP v7). Instead, you should take this opportunity to migrate your application now, before it's too late.

   Note also that this technique will suppress all E_DEPRECATED messages, not just those to do with the ext/mysql extension: therefore you may be unaware of other upcoming changes to PHP that would affect your application code. It is, of course, possible to only suppress errors that arise on the expression at issue by using PHP's error control operator—i.e. prepending the relevant line with @—however this will suppress all errors raised by that expression, not just E_DEPRECATED ones.

What should you do?

• You are starting a new project.

  There is absolutely no reason to use ext/mysql—choose one of the other, more modern, extensions instead and reap the rewards of the benefits they offer.

• You have (your own) legacy codebase that currently depends upon ext/mysql.

  It would be wise to perform regression testing: you really shouldn't be changing anything (especially upgrading PHP) until you have identified all of the potential areas of impact, planned around each of them and then thoroughly tested your solution in a staging environment.

  • Following good coding practice, your application was developed in a loosely integrated/modular fashion and the database access methods are all self-contained in one place that can easily be swapped out for one of the new extensions.

    Spend half an hour rewriting this module to use one of the other, more modern, extensions; test thoroughly. You can later introduce further refinements to reap the rewards of the benefits they offer.

  • The database access methods are scattered all over the place and cannot easily be swapped out for one of the new extensions.

    Consider whether you really need to upgrade to PHP v5.5 at this time.

    You should begin planning to replace ext/mysql with one of the other, more modern, extensions in order that you can reap the rewards of the benefits they offer; you might also use it as an opportunity to refactor your database access methods into a more modular structure.

    However, if you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

• You are using a third party project that depends upon ext/mysql.

  Consider whether you really need to upgrade to PHP v5.5 at this time.

  Check whether the developer has released any fixes, workarounds or guidance in relation to this specific issue; or, if not, pressure them to do so by bringing this matter to their attention. If you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

  It is absolutely essential to perform regression testing.

Cast the dtype of the col to str and you can perform vectorised slicing calling str:

In [29]:
df['new_col'] = df['First'].astype(str).str[0]
df

Out[29]:
   First  Second new_col
0    123     234       1
1     22    4353       2
2     32     355       3
3    453     453       4
4     45     345       4
5    453     453       4
6     56      56       5

if you need to you can cast the dtype back again calling astype(int) on the column

You can’t run arbitrary Python code in jinja; it doesn’t work like JSP in that regard (it just looks similar). All the things in jinja are custom syntax.

For your purpose, it would make most sense to define a custom filter, so you could for example do the following:

The grass is {{ variable1 | splitpart(0, ',') }} and the boat is {{  splitpart(1, ',') }}
Or just:
The grass is {{ variable1 | splitpart(0) }} and the boat is {{  splitpart(1) }}

The filter function could then look like this:

def splitpart (value, index, char = ','):
    return value.split(char)[index]

An alternative, which might make even more sense, would be to split it in the controller and pass the splitted list to the view.

Those are two different things, as others have mentioned.

When you specify # -*- coding: utf-8 -*-, you're telling Python the source file you've saved is utf-8. The default for Python 2 is ASCII (for Python 3 it's utf-8). This just affects how the interpreter reads the characters in the file.

In general, it's probably not the best idea to embed high unicode characters into your file no matter what the encoding is; you can use string unicode escapes, which work in either encoding.

When you declare a string with a u in front, like u'This is a string', it tells the Python compiler that the string is Unicode, not bytes. This is handled mostly transparently by the interpreter; the most obvious difference is that you can now embed unicode characters in the string (that is, u'\u2665' is now legal). You can use from __future__ import unicode_literals to make it the default.

This only applies to Python 2; in Python 3 the default is Unicode, and you need to specify a b in front (like b'These are bytes', to declare a sequence of bytes).

This is from a php script which solves the problem perfectly with every browser I've tested (FF since 3.5, IE8+, Chrome)

header("Content-Disposition: attachment; filename=\"".$fname_local."\"");
header("Content-Type: application/force-download");
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($fname));

So as far as I can see, you're doing everything correctly. Have you checked your browser settings?

If ant-contrib isn't an option, here's a portable solution for Java 1.6 and later:

<property name="before" value="This is a value"/>
<script language="javascript">
    var before = project.getProperty("before");
    project.setProperty("after", before.replaceAll(" ", "_"));
</script>
<echo>after=${after}</echo>

No library, using URL() WebAPI (https://developer.mozilla.org/en-US/docs/Web/API/URL)

function setURLParameter(url, parameter, value) {
    let url = new URL(url);
    if (url.searchParams.get(parameter) === value) {
        return url;
    }
    url.searchParams.set(parameter, value);
    return url.href;
}

This doesn't work on IE: https://developer.mozilla.org/en-US/docs/Web/API/URL#Browser_compatibility

Did a quick google. Seems that to find the file size you do this,

long size = f.length();

The differences between the three methods you posted can be found here

getFreeSpace() and getTotalSpace() are pretty self explanatory, getUsableSpace() seems to be the space that the JVM can use, which in most cases will be the same as the amount of free space.

I use below function to animate UiKit gear icon using Just JavaScript

document.getElementById("spin_it").onmouseover=function(e){_x000D_
var el = document.getElementById("spin_it");_x000D_
var Classes = el.className;_x000D_
var NewClass = Classes+" uk-icon-spin";_x000D_
el.className = NewClass;_x000D_
console.log(e);_x000D_
}

<span class="uk-icon uk-icon-small uk-icon-gear" id="spin_it"></span>

This code not work here...you must add UIKit Style to it

Alternatively for those using Maven build tool, there is a plugin called Surefire Report.

The report looks like this : Sample

str.match(/regex/g)

returns all matches as an array.

If, for some mysterious reason, you need the additional information comes with exec, as an alternative to previous answers, you could do it with a recursive function instead of a loop as follows (which also looks cooler :).

function findMatches(regex, str, matches = []) {
   const res = regex.exec(str)
   res && matches.push(res) && findMatches(regex, str, matches)
   return matches
}

// Usage
const matches = findMatches(/regex/g, str)

as stated in the comments before, it's important to have g at the end of regex definition to move the pointer forward in each execution.

Another possibility is to use the textwrap module. This also avoids the problem of "string just sitting in the middle of nowhere" as mentioned in the question.

import textwrap
mystr = """\
        Why, hello there
        wonderful stackoverfow people"""
print (textwrap.fill(textwrap.dedent(mystr)))

I liked qiao's first answer very much! The only thing missing here is to mark the vertexes as visited.

Why we need to do it?
Lets imagine that there is another node number 13 connected from node 11. Now our goal is to find node 13.
After a little bit of a run the queue will look like this:

[[1, 2, 6], [1, 3, 10], [1, 4, 7], [1, 4, 8], [1, 2, 5, 9], [1, 2, 5, 10]]

Note that there are TWO paths with node number 10 at the end.
Which means that the paths from node number 10 will be checked twice. In this case it doesn't look so bad because node number 10 doesn't have any children.. But it could be really bad (even here we will check that node twice for no reason..)
Node number 13 isn't in those paths so the program won't return before reaching to the second path with node number 10 at the end..And we will recheck it..

All we are missing is a set to mark the visited nodes and not to check them again..
This is qiao's code after the modification:

graph = {
    1: [2, 3, 4],
    2: [5, 6],
    3: [10],
    4: [7, 8],
    5: [9, 10],
    7: [11, 12],
    11: [13]
}


def bfs(graph_to_search, start, end):
    queue = [[start]]
    visited = set()

    while queue:
        # Gets the first path in the queue
        path = queue.pop(0)

        # Gets the last node in the path
        vertex = path[-1]

        # Checks if we got to the end
        if vertex == end:
            return path
        # We check if the current node is already in the visited nodes set in order not to recheck it
        elif vertex not in visited:
            # enumerate all adjacent nodes, construct a new path and push it into the queue
            for current_neighbour in graph_to_search.get(vertex, []):
                new_path = list(path)
                new_path.append(current_neighbour)
                queue.append(new_path)

            # Mark the vertex as visited
            visited.add(vertex)


print bfs(graph, 1, 13)

The output of the program will be:

[1, 4, 7, 11, 13]

Without the unneccecery rechecks..

I too encountered this issue while auto inserting a sysdate to a column.

What I did is I changed my system date format to match with SQL server's date format. e.g. my SQL format was mm/dd/yyyy and my system format was set to dd/mm/yyyy. I changed my system format to mm/dd/yyyy and error gone

-kb

In my case, I wanted to check out a new branch that has cut recently but it's it big in size and I want to save time and internet bandwidth, as I'm in a slow metered network

so I copped the previous branch that I already checked in

I went to the working directory, and from svn info, I can see it's on the previous branch I did the following command (you can find this command from svn switch --help)

svn switch ^/branches/newBranchName

go check svn info again you can see it is becoming the newBranchName go ahead and svn up

and this how I got the new branch easily, quickly with minimum data transmitting over the internet

hope sharing my case helps and speeds up your work

Install Flysystem:

composer require league/flysystem-sftp

Then:

use League\Flysystem\Filesystem;
use League\Flysystem\Sftp\SftpAdapter;

$filesystem = new Filesystem(new SftpAdapter([

    'port' => 22,
    'username' => 'username',
    'password' => 'password',
    'privateKey' => 'path/to/or/contents/of/privatekey',
    'root' => '/path/to/root',
    'timeout' => 10,
]));
$filesystem->listFiles($path); // get file lists
$filesystem->read($path_to_file); // grab file
$filesystem->put($path); // upload file

For a function type prop you can use the following code:

AddAddressComponent.defaultProps = {
    callBackHandler: () => {}
};

AddAddressComponent.propTypes = {
    callBackHandler: PropTypes.func,
};

With modern Python Exceptions, you don't need to abuse .message, or override .__str__() or .__repr__() or any of it. If all you want is an informative message when your exception is raised, do this:

class MyException(Exception):
    pass

raise MyException("My hovercraft is full of eels")

That will give a traceback ending with MyException: My hovercraft is full of eels.

If you want more flexibility from the exception, you could pass a dictionary as the argument:

raise MyException({"message":"My hovercraft is full of animals", "animal":"eels"})

However, to get at those details in an except block is a bit more complicated. The details are stored in the args attribute, which is a list. You would need to do something like this:

try:
    raise MyException({"message":"My hovercraft is full of animals", "animal":"eels"})
except MyException as e:
    details = e.args[0]
    print(details["animal"])

It is still possible to pass in multiple items to the exception and access them via tuple indexes, but this is highly discouraged (and was even intended for deprecation a while back). If you do need more than a single piece of information and the above method is not sufficient for you, then you should subclass Exception as described in the tutorial.

class MyError(Exception):
    def __init__(self, message, animal):
        self.message = message
        self.animal = animal
    def __str__(self):
        return self.message

You can use Regular Expressions with a dynamic pattern.

var text = "something";
var output = "                    ";
var pattern = new RegExp("^\\s{"+text.length+"}");
var output.replace(pattern,text);

outputs:

"something      "

This replaces text.length of whitespace characters at the beginning of the string output. The RegExp means ^\ - beginning of a line \s any white space character, repeated {n} times, in this case text.length. Use \\ to \ escape backslashes when building this kind of patterns out of strings.

Yeah, this is a platform dependent question.

If you are writing a console program on POSIX, use the signal API (#include <signal.h>).

In a WIN32 GUI application you should handle the WM_KEYDOWN message.

In Clean Code: A Handbook of Agile Software Craftsmanship there is an explicit recommendation against the usage of this prefix:

You also don't need to prefix member variables with m_ anymore. Your classes and functions should be small enough that you don't need them.

There is also an example (C# code) of this:

Bad practice:

public class Part
{
    private String m_dsc; // The textual description

    void SetName(string name)
    {
        m_dsc = name;
    }
}

Good practice:

public class Part
{
    private String description;

    void SetDescription(string description)
    {
        this.description = description;
    }
}

We count with language constructs to refer to member variables in the case of explicitly ambiguity (i.e., description member and description parameter): this.

As per source code

function ReactComponent(props, context) {
  this.props = props;
  this.context = context;
}

you must pass props every time you have props and you don't put them into this.props manually.

A continue statement without a label will re-execute from the condition the innermost while or do loop, and from the update expression of the innermost for loop. It is often used to early-terminate a loop's processing and thereby avoid deeply-nested if statements. In the following example continue will get the next line, without processing the following statement in the loop.

while (getNext(line)) {
  if (line.isEmpty() || line.isComment())
    continue;
  // More code here
}

With a label, continue will re-execute from the loop with the corresponding label, rather than the innermost loop. This can be used to escape deeply-nested loops, or simply for clarity.

Sometimes continue is also used as a placeholder in order to make an empty loop body more clear.

for (count = 0; foo.moreData(); count++)
  continue;

The same statement without a label also exists in C and C++. The equivalent in Perl is next.

This type of control flow is not recommended, but if you so choose you can also use continue to simulate a limited form of goto. In the following example the continue will re-execute the empty for (;;) loop.

aLoopName: for (;;) {
  // ...
  while (someCondition)
  // ...
    if (otherCondition)
      continue aLoopName;

No need to use sub query, just Try this,Its working fine:

  DB::table('orders')->orderBy('id', 'desc')->first();

I opened XCode -> Preferences -> Accounts and clicked on Download certificate. That fixed my problem

Found another solution for the same. It will be more helpful.

START C:\"Program Files (x86)"\Test\"Test Automation"\finger.exe ConfigFile="C:\Users\PCName\Desktop\Automation\Documents\Validation_ZoneWise_Default.finger.Config"

finger.exe is a parent program that is calling config solution. Note: if your path folder name consists of spaces, then do not forget to add "".

If you don't want to duplicate code, and like me you just want to show stats, in your view model, you could just pass in the models you want to get data from like so:

public class GameViewModel
{
    public virtual Ship Ship { get; set; }
    public virtual GamePlayer GamePlayer { get; set; }     
}

Then, in your controller just run your queries on the respective models, pass them to the view model and return it, example:

GameViewModel PlayerStats = new GameViewModel();

GamePlayer currentPlayer = (from c in db.GamePlayer [more queries]).FirstOrDefault();

[code to check if results]

//pass current player into custom view model
PlayerStats.GamePlayer = currentPlayer;

Like I said, you should only really do this if you want to display stats from the relevant tables, and there's no other part of the CRUD process happening, for security reasons other people have mentioned above.

I ended up setting my own drop shadow for the toolbar, thought it might helpful for anyone looking for it:

I found this post while looking at this other SO post. Below is a copy of the answer I gave there.

I know this is an old thread, but React has become popular and, perhaps, someone using React will come here looking for an answer to the same problem.

So, if you are using React, you can do something like the below, which was an answer original provided by Ben Alpert of the React team here

getInitialState: function(event) {
    return {image: "http://example.com/primary_image.jpg"};
},
handleError: function(event) {
    this.setState({image: "http://example.com/failover_image.jpg"});
},
render: function() {
    return (
        <img onError={this.handleError} src={src} />;
    );
}

Usually it happen in TochableHighlight. Anyway error mean that you must used single element inside the whatever component.

Solution : You can use single view inside parent and anything can be used inside that View. See the attached picture

File Path Seems to be an issue here please make sure that file exists in the correct directory or give the absolute path to make sure that you are pointing to a correct file. Please log the file.getAbsolutePath() to verify that file is correct.

A way for easy reading is...

//Remove milliseconds
DateTime date = DateTime.Now;
date = DateTime.ParseExact(date.ToString("yyyy-MM-dd HH:mm:ss"), "yyyy-MM-dd HH:mm:ss", null);

And more...

//Remove seconds
DateTime date = DateTime.Now;
date = DateTime.ParseExact(date.ToString("yyyy-MM-dd HH:mm"), "yyyy-MM-dd HH:mm", null);

//Remove minutes
DateTime date = DateTime.Now;
date = DateTime.ParseExact(date.ToString("yyyy-MM-dd HH"), "yyyy-MM-dd HH", null);

//and go on...

The important point is that the list comprehension creates a new list. The generator creates a an iterable object that will "filter" the source material on-the-fly as you consume the bits.

Imagine you have a 2TB log file called "hugefile.txt", and you want the content and length for all the lines that start with the word "ENTRY".

So you try starting out by writing a list comprehension:

logfile = open("hugefile.txt","r")
entry_lines = [(line,len(line)) for line in logfile if line.startswith("ENTRY")]

This slurps up the whole file, processes each line, and stores the matching lines in your array. This array could therefore contain up to 2TB of content. That's a lot of RAM, and probably not practical for your purposes.

So instead we can use a generator to apply a "filter" to our content. No data is actually read until we start iterating over the result.

logfile = open("hugefile.txt","r")
entry_lines = ((line,len(line)) for line in logfile if line.startswith("ENTRY"))

Not even a single line has been read from our file yet. In fact, say we want to filter our result even further:

long_entries = ((line,length) for (line,length) in entry_lines if length > 80)

Still nothing has been read, but we've specified now two generators that will act on our data as we wish.

Lets write out our filtered lines to another file:

outfile = open("filtered.txt","a")
for entry,length in long_entries:
    outfile.write(entry)

Now we read the input file. As our for loop continues to request additional lines, the long_entries generator demands lines from the entry_lines generator, returning only those whose length is greater than 80 characters. And in turn, the entry_lines generator requests lines (filtered as indicated) from the logfile iterator, which in turn reads the file.

So instead of "pushing" data to your output function in the form of a fully-populated list, you're giving the output function a way to "pull" data only when its needed. This is in our case much more efficient, but not quite as flexible. Generators are one way, one pass; the data from the log file we've read gets immediately discarded, so we can't go back to a previous line. On the other hand, we don't have to worry about keeping data around once we're done with it.

I think you have to write some extra code. For example:

if 'MICHAEL89' in map(lambda name: name.upper(), USERNAMES):
   ...

In this case we are forming a new list with all entries in USERNAMES converted to upper case and then comparing against this new list.

Update

As @viraptor says, it is even better to use a generator instead of map. See @Nathon's answer.

Alternatively, you could use tensorflow for the cropping and openCV for making an array from the image.

import cv2
img = cv2.imread('YOURIMAGE.png')

Now img is a (imageheight, imagewidth, 3) shape array. Crop the array with tensorflow:

import tensorflow as tf
offset_height=0
offset_width=0
target_height=500
target_width=500
x = tf.image.crop_to_bounding_box(
    img, offset_height, offset_width, target_height, target_width
)

Reassemble the image with tf.keras, so we can look at it if it worked:

tf.keras.preprocessing.image.array_to_img(
    x, data_format=None, scale=True, dtype=None
)

This prints out the pic in a notebook (tested in Google Colab).

The whole code together:

import cv2
img = cv2.imread('YOURIMAGE.png')

import tensorflow as tf
offset_height=0
offset_width=0
target_height=500
target_width=500
x = tf.image.crop_to_bounding_box(
    img, offset_height, offset_width, target_height, target_width
)

tf.keras.preprocessing.image.array_to_img(
    x, data_format=None, scale=True, dtype=None
)

What size this image should be depends on where it is to be used.

It is up to applications, eg WhatsApp, Facebook Messenger, Reddit, etc etc to decide what to do with the image. Some use it as a square image, some as a 1:19.1 rectangle, and some use different sizes when the display environment is of different sizes even for the same application. There are no rules, and there is no way to control what applications do with the image.

So you should test out the image on your intended target application(s) and find a compromise. That applications tend to cache the image makes it a pain on the trial and error approach.

this is the correct answer

$('#theid').css('display') == 'none'

You can also use following line to find if it is display block or none

$('.deal_details').is(':visible')

"Segmentation fault" means that you tried to access memory that you do not have access to.

The first problem is with your arguments of main. The main function should be int main(int argc, char *argv[]), and you should check that argc is at least 2 before accessing argv[1].

Also, since you're passing in a float to printf (which, by the way, gets converted to a double when passing to printf), you should use the %f format specifier. The %s format specifier is for strings ('\0'-terminated character arrays).

The good way to draw a Drawable on a canvas is not decoding it yourself but leaving it to the system to do so:

Drawable d = getResources().getDrawable(R.drawable.foobar, null);
d.setBounds(left, top, right, bottom);
d.draw(canvas);

This will work with all kinds of drawables, not only bitmaps. And it also means that you can re-use that same drawable again if only the size changes.

If you are using JQuery 1.9+ then above answers will not work in Firefox.

So here is a code for latest jquery which will work in all browsers.

See live demo

Here is the code

var select_ids = [];
$(document).ready(function(e) {
    $('select#myselect option').each(function(index, element) {
        select_ids.push($(this).val());
    })
});

function selectAll()
{
    $('select#myselect').val(select_ids);
}

function deSelectAll()
{
    $('select#myselect').val('');
}

Hope this will help you... :)

Instead of using log4net which is an external library I have created my own simple class, highly customizable and easy to use (edit YOURNAMESPACEHERE with the namespace that you need).

CONSOLE APP

using System;
using System.IO;

namespace YOURNAMESPACEHERE
{
    enum LogEvent
    {
        Info = 0,
        Success = 1,
        Warning = 2,
        Error = 3
    }

    internal static class Log
    {
        private static readonly string LogSession = DateTime.Now.ToLocalTime().ToString("ddMMyyyy_HHmmss");
        private static readonly string LogPath = AppDomain.CurrentDomain.BaseDirectory + "logs";

        internal static void Write(LogEvent Level, string Message, bool ShowConsole = true, bool WritelogFile = true)
        {
            string Event = string.Empty;
            ConsoleColor ColorEvent = Console.ForegroundColor;

            switch (Level)
            {
                case LogEvent.Info:
                    Event = "INFO";
                    ColorEvent = ConsoleColor.White;
                    break;
                case LogEvent.Success:
                    Event = "SUCCESS";
                    ColorEvent = ConsoleColor.Green;
                    break;
                case LogEvent.Warning:
                    Event = "WARNING";
                    ColorEvent = ConsoleColor.Yellow;
                    break;
                case LogEvent.Error:
                    Event = "ERROR";
                    ColorEvent = ConsoleColor.Red;
                    break;
            }

            if (ShowConsole)
            {
                Console.ForegroundColor = ColorEvent;
                Console.WriteLine(" [{0}] => {1}", DateTime.Now.ToString("HH:mm:ss"), Message);
                Console.ResetColor();
            }

            if (WritelogFile)
            {
                if (!Directory.Exists(LogPath))
                    Directory.CreateDirectory(LogPath);

                File.AppendAllText(LogPath + @"\" + LogSession + ".log", string.Format("[{0}] => {1}: {2}\n", DateTime.Now.ToString("HH:mm:ss"), Event, Message));
            }
        }
    }
}

NO CONSOLE APP (ONLY LOG)

using System;
using System.IO;

namespace YOURNAMESPACEHERE
{
    enum LogEvent
    {
        Info = 0,
        Success = 1,

        Error = 3
    }

internal static class Log
{

    private static readonly string LogPath = AppDomain.CurrentDomain.BaseDirectory + "logs";

    internal static void Write(LogEvent Level, string Message)
    {
        string Event = string.Empty;

        switch (Level)
        {
            case LogEvent.Info:

            case LogEvent.Error:
                Event = "ERROR";
                break;
        }

        if (!Directory.Exists(LogPath))
            Directory.CreateDirectory(LogPath);

        File.AppendAllText(LogPath + @"\" + LogSession + ".log", string.Format("[{0}] => {1}: {2}\n", DateTime.Now.ToString("HH:mm:ss"), Event, Message));
    }
}

Usage:

CONSOLE APP

Log.Write(LogEvent.Info, "Test message"); // It will print an info in your console, also will save a copy of this print in a .log file.
Log.Write(LogEvent.Warning, "Test message", false); // It will save the print as warning only in your .log file.
Log.Write(LogEvent.Error, "Test message", true, false); // It will print an error only in your console.

NO CONSOLE APP (ONLY LOG)

Log.Write(LogEvent.Info, "Test message"); // It will print an info in your .log file.

Try to give max-contentfor parent's height.

I had no luck until I installed the 2010 version link here: https://www.microsoft.com/en-us/download/details.aspx?id=13255

I tried installing the 32 bit version, it still errored, so I uninstalled it and installed the 64 bit version and it started working.

This is an ugly but fast solution: use JDK 6 instead of 7.

After read Chloe's answer, I uninstalled my JDK 7 (don't need it currently anyways) and installed JDK 6. That fixed it. A better solution would make ant uses JDK 6 (without uninstalling 7). Maybe possible changing / setting this property:

java.library.path

in local.properties file. It's in the project directory (root).

Android doesn't work with JDK 7 anyways (only 6 or 5), so make that the ant script also uses JDK 6 or 5 is probably a good solution.

The comp.lang.c FAQ deals with the question

"What's the correct declaration of main()?"
