I'm assume you cannot get css working for your button using anchor tag. So you need to override the css styles which are being overwritten by other elements using !important property.

HTML

<a href="#" class="selected_btn" data-role="button">Button name</a>

CSS

.selected_btn
{
    border:1px solid red;
    text-decoration:none;
    font-family:helvetica;
    color:red !important;            
    background:url('http://www.lessardstephens.com/layout/images/slideshow_big.png') repeat-x;
}

Here is the demo

The column names which are mixed case or uppercase have to be double quoted in PostgresQL. So best convention will be to follow all small case with underscore.

This can be done in WebKit-based browsers (such as Chrome and Safari) with only CSS:

::-webkit-scrollbar {
    width: 2em;
    height: 2em
}
::-webkit-scrollbar-button {
    background: #ccc
}
::-webkit-scrollbar-track-piece {
    background: #888
}
::-webkit-scrollbar-thumb {
    background: #eee
}?

You can memcpy structs, or you can just assign them like any other value.

struct {int a, b;} c, d;
c.a = c.b = 10;
d = c;

First Talk About

Normal Class - that's mean any class define that's a normally in java it's means you create different type of method properties etc.
Bean - Bean is nothing it's only a object of that particular class using this bean you can access your java class same as object..

and after that talk about last one POJO

POJO - POJO is that class which have no any services it's have only a default constructor and private property and those property for setting a value corresponding setter and getter methods. It's short form of Plain Java Object.

Use @SessionAttributes

See the docs: Using @SessionAttributes to store model attributes in the HTTP session between requests

"Understanding Spring MVC Model And Session Attributes" also gives a very good overview of Spring MVC sessions and explains how/when @ModelAttributes are transferred into the session (if the controller is @SessionAttributes annotated).

That article also explains that it is better to use @SessionAttributes on the model instead of setting attributes directly on the HttpSession because that helps Spring MVC to be view-agnostic.

You may use display:table/table-cell;

.a{_x000D_
   position: absolute; _x000D_
  left: 50px; _x000D_
  top: 50px;_x000D_
  display:table;_x000D_
}_x000D_
.b{_x000D_
  text-align: left; _x000D_
  display:table-cell;_x000D_
  height: 56px;_x000D_
  vertical-align: middle;_x000D_
  background-color: pink;_x000D_
}_x000D_
.c {_x000D_
  background-color: lightblue;_x000D_
}

<div class="a">_x000D_
  <div  class="b">_x000D_
    <div class="c" >test</div>_x000D_
  </div>_x000D_
</div>

It's go to newline then add spaces to start second line at end of first line

Output

Hello
     Goodbye

It's worth noting CSS3 substring attribute selectors

[attribute^=value] { /* starts with selector */
/* Styles */
}

[attribute$=value] { /* ends with selector */
/* Styles */
}

[attribute*=value] { /* contains selector */
/* Styles */
}

Inspecting and mocking request body

When you first read the body, you have to store it so once you're done with it, you can set a new io.ReadCloser as the request body constructed from the original data. So when you advance in the chain, the next handler can read the same body.

One option is to read the whole body using ioutil.ReadAll(), which gives you the body as a byte slice.

You may use bytes.NewBuffer() to obtain an io.Reader from a byte slice.

The last missing piece is to make the io.Reader an io.ReadCloser, because bytes.Buffer does not have a Close() method. For this you may use ioutil.NopCloser() which wraps an io.Reader, and returns an io.ReadCloser, whose added Close() method will be a no-op (does nothing).

Note that you may even modify the contents of the byte slice you use to create the "new" body. You have full control over it.

^{Care must be taken though, as there might be other HTTP fields like content-length and checksums which may become invalid if you modify only the data. If subsequent handlers check those, you would also need to modify those too!}

Inspecting / modifying response body

If you also want to read the response body, then you have to wrap the http.ResponseWriter you get, and pass the wrapper on the chain. This wrapper may cache the data sent out, which you can inspect either after, on on-the-fly (as the subsequent handlers write to it).

Here's a simple ResponseWriter wrapper, which just caches the data, so it'll be available after the subsequent handler returns:

type MyResponseWriter struct {
    http.ResponseWriter
    buf *bytes.Buffer
}

func (mrw *MyResponseWriter) Write(p []byte) (int, error) {
    return mrw.buf.Write(p)
}

Note that MyResponseWriter.Write() just writes the data to a buffer. You may also choose to inspect it on-the-fly (in the Write() method) and write the data immediately to the wrapped / embedded ResponseWriter. You may even modify the data. You have full control.

^{Care must be taken again though, as the subsequent handlers may also send HTTP response headers related to the response data –such as length or checksums– which may also become invalid if you alter the response data.}

Full example

Putting the pieces together, here's a full working example:

func loginmw(handler http.Handler) http.Handler {
    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
        body, err := ioutil.ReadAll(r.Body)
        if err != nil {
            log.Printf("Error reading body: %v", err)
            http.Error(w, "can't read body", http.StatusBadRequest)
            return
        }

        // Work / inspect body. You may even modify it!

        // And now set a new body, which will simulate the same data we read:
        r.Body = ioutil.NopCloser(bytes.NewBuffer(body))

        // Create a response wrapper:
        mrw := &MyResponseWriter{
            ResponseWriter: w,
            buf:            &bytes.Buffer{},
        }

        // Call next handler, passing the response wrapper:
        handler.ServeHTTP(mrw, r)

        // Now inspect response, and finally send it out:
        // (You can also modify it before sending it out!)
        if _, err := io.Copy(w, mrw.buf); err != nil {
            log.Printf("Failed to send out response: %v", err)
        }
    })
}

def get_dict_from_pd(df, key_col, row_col):
    result = dict()
    for i in set(df[key_col].values):
        is_i = df[key_col] == i
        result[i] = list(df[is_i][row_col].values)
    return result

this is my sloution, a basic loop

I think it also worth to mention that in case the SSH protocol can not be used for some reason and modifying a private repository http(s) URL to provide basic authentication credentials is not an option either, there's an alternative as well.

The basic authentication header can be configured using http.extraHeader git-config option:

git config --global --unset-all "http.https://github.com/.extraheader"
git config --global --add "http.https://github.com/.extraheader" \
          "AUTHORIZATION: Basic $(base64 <<< [access-token-string]:x-oauth-basic)"

Where [access-token-string] placeholder should be replaced (including square braces) with a generated real token value. You can read more about access tokens here and here.

If the configuration has been applied properly then the configured AUTHORIZATION header will be included in each HTTPS request to the github.com IP address accessed by git command.

You could set content as data attribute and then use attribute selectors, as shown here:

/* Select every cell containing word "male" */
td[data-content="male"] {
  color: red;
}

/* Select every cell starting on "p" case insensitive */
td[data-content^="p" i] {
  color: blue;
}

/* Select every cell containing "4" */
td[data-content*="4"] {
  color: green;
}

<table>
  <tr>
    <td data-content="Peter">Peter</td>
    <td data-content="male">male</td>
    <td data-content="34">34</td>
  </tr>
  <tr>
    <td data-content="Susanne">Susanne</td>
    <td data-content="female">female</td>
    <td data-content="14">14</td>
  </tr>
</table>

You can also use jQuery to easily set the data-content attributes:

$(function(){
  $("td").each(function(){
    var $this = $(this);
    $this.attr("data-content", $this.text());
  });
});

CURLOPT_USERPWD basically sends the base64 of the user:password string with http header like below:

Authorization: Basic dXNlcjpwYXNzd29yZA==

So apart from the CURLOPT_USERPWD you can also use the HTTP-Request header option as well like below with other headers:

$headers = array(
    'Content-Type:application/json',
    'Authorization: Basic '. base64_encode("user:password") // <---
);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

New location for mysql config file is

/etc/mysql/mysql.conf.d/mysqld.cnf

After checking the default locations on Win7 with mysql --help and unable to find any config file, I manually searched for my.ini and found it at C:\ProgramData\MySQL\MySQL Server x.y (yep, ProgramData, not Program Files).

Though I used an own my.ini at Program Files, the other configuration overwrote my settings.

The security's authorization check part gets the authenticated object from SecurityContext, which will be set when a request gets through the spring security filter. My assumption here is that soon after the login this is not being set. You probably can use a hack as given below to set the value.

try {
    SecurityContext ctx = SecurityContextHolder.createEmptyContext();
    SecurityContextHolder.setContext(ctx);
    ctx.setAuthentication(event.getAuthentication());

    //Do what ever you want to do

} finally {
    SecurityContextHolder.clearContext();
}

Update:

Also you can have a look at the InteractiveAuthenticationSuccessEvent which will be called once the SecurityContext is set.

It is permission issue in my case the task scheduler has a user which doesn't have permission on the server in which the database is present.

Change your append calls to say

...append(iter->first)

and

... append(iter->second)

Additionally, the line

std::string* strToReturn = new std::string("");

allocates a string on the heap. If you intend to actually return a pointer to this dynamically allocated string, the return should be changed to std::string*.

Alternatively, if you don't want to worry about managing that object on the heap, change the local declaration to

std::string strToReturn("");

and change the 'append' calls to use reference syntax...

strToReturn.append(...)

instead of

strToReturn->append(...)

Be aware that this will construct the string on the stack, then copy it into the return variable. This has performance implications.

Keeping your commands short will make them easier to remember:

git log --graph --oneline

Try the following:

sudo rm /var/lib/mongodb/mongod.lock
sudo service mongodb restart

if you do not want to create a custom class loader. You can read the jar file stream. And transfer it to a File object. Then you can get the url of the File. Send it to the URLClassLoader, you can load the jar file as you want. sample:

InputStream resourceAsStream = this.getClass().getClassLoader().getResourceAsStream("example"+ ".jar");
final File tempFile = File.createTempFile("temp", ".jar");
tempFile.deleteOnExit();  // you can delete the temp file or not
try (FileOutputStream out = new FileOutputStream(tempFile)) {
    IOUtils.copy(resourceAsStream, out);
}
IOUtils.closeQuietly(resourceAsStream);
URL url = tempFile.toURI().toURL();
URLClassLoader urlClassLoader = new URLClassLoader(new URL[]{url});
urlClassLoader.loadClass()
...

use:

<div class="row form-group"></div>

list.groupBy(i=>i).mapValues(_.size)

gives

Map[Int, Int] = Map(1 -> 1, 2 -> 3, 7 -> 1, 3 -> 1, 4 -> 3)

Note that you can replace (i=>i) with built in identity function:

list.groupBy(identity).mapValues(_.size)

So after doing more investigating I ended up going with a slightly revised version of Method 3 (mgechev/angular2-seed).

I basically moved components to be a main level directory and then each feature will be inside of it.

Remove the content of the folder \.m2\repository\org\apache\maven\plugins\maven-resource-plugin\2.7. The cached info turned out to be the issue.

This might not suit everyone since it does not preserve the original file permissions but in my case it was not important and it solved the problem for me. rsync has an option --chmod:

--chmod This option tells rsync to apply one or more comma-separated lqchmodrq strings to the permission of the files in the transfer. The resulting value is treated as though it was the permissions that the sending side supplied for the file, which means that this option can seem to have no effect on existing files if --perms is not enabled.

This forces the permissions to be what you want on all files/directories. For example:

rsync -av --chmod=Du+rwx SRC DST

would add Read, Write and Execute for the user to all transferred directories.

$('.submit').filter(':checked').each(function() {
    //This is same as 'continue'
    if(something){
        return true;
    }
    //This is same as 'break'
    if(something){
        return false;
    }
});

Web API works very nicely if you accept the fact that you are using HTTP. It's when you start trying to pretend that you are sending objects over the wire that it starts to get messy.

 public class TextController : ApiController
    {
        public HttpResponseMessage Post(HttpRequestMessage request) {

            var someText = request.Content.ReadAsStringAsync().Result;
            return new HttpResponseMessage() {Content = new StringContent(someText)};

        }

    }

This controller will handle a HTTP request, read a string out of the payload and return that string back.

You can use HttpClient to call it by passing an instance of StringContent. StringContent will be default use text/plain as the media type. Which is exactly what you are trying to pass.

    [Fact]
    public void PostAString()
    {

        var client = new HttpClient();

        var content = new StringContent("Some text");
        var response = client.PostAsync("http://oak:9999/api/text", content).Result;

        Assert.Equal("Some text",response.Content.ReadAsStringAsync().Result);

    }

It has 2 purposes.

yentup has given the first one.

It's used for raising your own errors.

if something:
    raise Exception('My error!')

The second is to reraise the current exception in an exception handler, so that it can be handled further up the call stack.

try:
  generate_exception()
except SomeException as e:
  if not can_handle(e):
    raise
  handle_exception(e)

one more approach to use.

first, define the following somewhere on the page:

<div id="valueHolderId">${someValue}</div>

then in JS, just do something similar to

var someValue = $('#valueHolderId').html();

it works great for the cases when all scripts are inside .js files and obviously there is no jstl available

You know that Maven is based on the Convention over Configuration pardigm? so you shouldn't configure things which are the defaults.

All that stuff represents the default in Maven. So best practice is don't define it it's already done.

    <directory>target</directory>
    <outputDirectory>target/classes</outputDirectory>
    <testOutputDirectory>target/test-classes</testOutputDirectory>
    <sourceDirectory>src/main/java</sourceDirectory>
    <testSourceDirectory>src/test/java</testSourceDirectory>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
        </resource>
    </resources>
    <testResources>
        <testResource>
            <directory>src/test/resources</directory>
        </testResource>
    </testResources>

Try

System.getProperty("user.dir")

It returns the current working directory.

This can happen if you accidentally are not dragging the element that does have an id assigned (for example you are dragging the surrounding element). In that case the ID is empty and the function drag() is assigning an empty value which is then passed to drop() and fails there.

Try assigning the ids to all of your elements, including the tds, divs, or whatever is around your draggable element.

If you are willing to use custom table header as table header, try the followings....

Updated for swift 3.0

Step 1

Create UITableViewHeaderFooterView for custom header..

import UIKit

class MapTableHeaderView: UITableViewHeaderFooterView {

    @IBOutlet weak var testView: UIView!

}

Step 2

Add custom header to UITableView

    override func viewDidLoad() {
            super.viewDidLoad()

            tableView.delegate = self
            tableView.dataSource = self

            //register the header view

            let nibName = UINib(nibName: "CustomHeaderView", bundle: nil)
            self.tableView.register(nibName, forHeaderFooterViewReuseIdentifier: "CustomHeaderView")


    }

    extension BranchViewController : UITableViewDelegate{

    }

    extension BranchViewController : UITableViewDataSource{

        func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
            return 200
        }

        func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
            let headerView = self.tableView.dequeueReusableHeaderFooterView(withIdentifier: "CustomHeaderView" ) as! MapTableHeaderView

            return headerView
        }

        func tableView(_ tableView: UITableView, numberOfRowsInSection section: 

    Int) -> Int {
            // retuen no of rows in sections
        }

        func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { 
            // retuen your custom cells    
        }

        func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

        }

        func numberOfSections(in tableView: UITableView) -> Int {
            // retuen no of sections
        }

        func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
            // retuen height of row
        }


    }

Try moving the order by clause outside sub select and add the order by field in sub select

SELECT * FROM 

(SELECT COUNT(1) ,refKlinik_id FROM Seanslar WHERE MONTH(tarihi) = 4 GROUP BY refKlinik_id)
as dorduncuay 

ORDER BY refKlinik_id 

http://api.jquery.com/on/ states:

When jQuery calls a handler, the this keyword is a reference to the element where the event is being delivered; for directly bound events this is the element where the event was attached and for delegated events this is an element matching selector. (Note that this may not be equal to event.target if the event has bubbled from a descendant element.)

To create a jQuery object from the element so that it can be used with jQuery methods, use $( this ).

If we have

<input type="button" class="btn" value ="btn1">
<input type="button" class="btn" value ="btn2">
<input type="button" class="btn" value ="btn3">

<div id="outer">
    <input type="button"  value ="OuterB" id ="OuterB">
    <div id="inner">
        <input type="button" class="btn" value ="InnerB" id ="InnerB">
    </div>
</div>

Check the below output:

<script>
    $(function(){
        $(".btn").on("click",function(event){
            console.log($(this));
            console.log($(event.currentTarget));
            console.log($(event.target));
        });


        $("#outer").on("click",function(event){
            console.log($(this));
            console.log($(event.currentTarget));
            console.log($(event.target));
        })
    })
</script>

Note that I use $ to wrap the dom element in order to create a jQuery object, which is how we always do.

You would find that for the first case, this ,event.currentTarget,event.target are all referenced to the same element.

While in the second case, when the event delegate to some wrapped element are triggered, event.target would be referenced to the triggered element, while this and event.currentTarget are referenced to where the event is delivered.

For this and event.currentTarget, they are exactly the same thing according to http://api.jquery.com/event.currenttarget/

You can convert JSON Date to normal date format in JavaScript.

var date = new Date(parseInt(jsonDate.substr(6)));

While later versions of Windows have a where command, you can also do this with Windows XP by using the environment variable modifiers, as follows:

c:\> for %i in (cmd.exe) do @echo.   %~$PATH:i
   C:\WINDOWS\system32\cmd.exe

c:\> for %i in (python.exe) do @echo.   %~$PATH:i
   C:\Python25\python.exe

You don't need any extra tools and it's not limited to PATH since you can substitute any environment variable (in the path format, of course) that you wish to use.

And, if you want one that can handle all the extensions in PATHEXT (as Windows itself does), this one does the trick:

@echo off
setlocal enableextensions enabledelayedexpansion

:: Needs an argument.

if "x%1"=="x" (
    echo Usage: which ^<progName^>
    goto :end
)

:: First try the unadorned filenmame.

set fullspec=
call :find_it %1

:: Then try all adorned filenames in order.

set mypathext=!pathext!
:loop1
    :: Stop if found or out of extensions.

    if "x!mypathext!"=="x" goto :loop1end

    :: Get the next extension and try it.

    for /f "delims=;" %%j in ("!mypathext!") do set myext=%%j
    call :find_it %1!myext!

:: Remove the extension (not overly efficient but it works).

:loop2
    if not "x!myext!"=="x" (
        set myext=!myext:~1!
        set mypathext=!mypathext:~1!
        goto :loop2
    )
    if not "x!mypathext!"=="x" set mypathext=!mypathext:~1!

    goto :loop1
:loop1end

:end
endlocal
goto :eof

:: Function to find and print a file in the path.

:find_it
    for %%i in (%1) do set fullspec=%%~$PATH:i
    if not "x!fullspec!"=="x" @echo.   !fullspec!
    goto :eof

It actually returns all possibilities but you can tweak it quite easily for specific search rules.

A quick string "GOTCHA" with JSON Unmarshall which will add wrapping quotes to strings.

(example: the string value of {"first_name":" I have whitespace "} will convert to "\" I have whitespace \"")

Before you can trim anything, you'll need to remove the extra quotes first:

playground example

// ScrubString is a string that might contain whitespace that needs scrubbing.
type ScrubString string

// UnmarshalJSON scrubs out whitespace from a valid json string, if any.
func (s *ScrubString) UnmarshalJSON(data []byte) error {
    ns := string(data)
    // Make sure we don't have a blank string of "\"\"".
    if len(ns) > 2 && ns[0] != '"' && ns[len(ns)] != '"' {
        *s = ""
        return nil
    }
    // Remove the added wrapping quotes.
    ns, err := strconv.Unquote(ns)
    if err != nil {
        return err
    }
    // We can now trim the whitespace.
    *s = ScrubString(strings.TrimSpace(ns))

    return nil
}

To add to @Sam_D's answer, I had to do this to make it work:

this.setTitle("my title!");
((TextView)v.findViewById(R.id.title)).setText(this.getTitle());
TextView title = ((TextView)v.findViewById(R.id.title));
title.setEllipsize(TextUtils.TruncateAt.MARQUEE);
title.setMarqueeRepeatLimit(1);
// in order to start strolling, it has to be focusable and focused
title.setFocusable(true);
title.setSingleLine(true);
title.setFocusableInTouchMode(true);
title.requestFocus();

It seems like overkill - referencing v.findViewById(R.id.title)) twice - but that's the only way it would let me do it.

If you are working on a project which does not require the use of IIS, then a workaround to open the project with this error is to simply right click on the unloaded project and click edit, search for:

<ProjectExtensions>
    <VisualStudio>
      <FlavorProperties GUID="">

In XAML, add and define a RowStyle Property for the DataGrid with a goal to set the Background of the Row, to the Color defined in my Employee Object.

<DataGrid AutoGenerateColumns="False" ItemsSource="EmployeeList">
   <DataGrid.RowStyle>
        <Style TargetType="DataGridRow">
             <Setter Property="Background" Value="{Binding ColorSet}"/>
        </Style>
   </DataGrid.RowStyle>

And in my Employee Class

public class Employee {

    public int Id { get; set; }
    public string Name { get; set; }
    public int Age { get; set; }

    public string ColorSet { get; set; }

    public Employee() { }

    public Employee(int id, string name, int age)
    {
        Id = id;
        Name = name;
        Age = age;
        if (Age > 50)
        {
            ColorSet = "Green";
        }
        else if (Age > 100)
        {
            ColorSet = "Red";
        }
        else
        {
            ColorSet = "White";
        }
    }
}

This way every Row of the DataGrid has the BackGround Color of the ColorSet Property of my Object.

That would just be:

 Console.WriteLine(Variables.name);

and it needs to be public also:

public class Variables
{
   public static string name = "";
}

I think the best way to do this is:

t = (1,2,3)

print "This is a tuple: %s" % str(t)

If you're familiar with printf style formatting, then Python supports its own version. In Python, this is done using the "%" operator applied to strings (an overload of the modulo operator), which takes any string and applies printf-style formatting to it.

In our case, we are telling it to print "This is a tuple: ", and then adding a string "%s", and for the actual string, we're passing in a string representation of the tuple (by calling str(t)).

If you're not familiar with printf style formatting, I highly suggest learning, since it's very standard. Most languages support it in one way or another.

This gives you the root folder:

System.AppDomain.CurrentDomain.BaseDirectory

You can navigate from here using .. or ./ etc.. , Appending .. takes you to folder where .sln file can be found

For .NET framework (thanks to Adiono comment)

Path.GetFullPath(Path.Combine(AppDomain.CurrentDomain.BaseDirectory,"..\\..\\"))

For .NET core here is a way to do it (thanks to nopara73 comment)

Path.GetFullPath(Path.Combine(AppContext.BaseDirectory, "..\\..\\..\\")) ;

Toni's answer is very useful, but I thought a quick start for total beginners to test coverage assessment (like I am).

As already mentioned, Visual Studio Professional and Community Editions do not have built-in test coverage support. However, it can be obtained quite easily. I will write step-by-step configuration for use with NUnit tests within Visual Studion 2015 Professional.

1. Install OpenCover NUGet component using NuGet interface

2. Get OpenCoverUI extension. This can be installed directly from Visual Studio by using Tools -> Extensions and Updates

3. Configure OpenCoverUI to use the appropriate executables, by accessing Tools -> Options -> OpenCover.UI Options -> General

NUnit Path: must point to the `nunit-console.exe file. This can be found only within NUnit 2.xx version, which can be downloaded from here.

OpenCover Path: this should point to the installed package, usually <solution path>\packages\OpenCover.4.6.519\tools\OpenCover.Console.exe

4. Install ReportGenerator NUGet package

5. Access OpenCover Test Explorer from OpenCover menu. Try discovering tests from there. If it fails, check Output windows for more details.

6. Check OpenCover Results (within OpenCover menu) for more details. It will output details such as Code Coverage in a tree based view. You can also highlight code that is or is not covered (small icon in the top-left).

NOTE: as mentioned, OpenCoverUI does not support latest major version of NUnit (3.xx). However, if nothing specific to this version is used within tests, it will work with no problems, regardless of having installed NUnit 3.xx version.

This covers the quick start. As already mentioned in the comments, for more advanced configuration and automation check this article.

You need to take extra precautions when using user supplied data in HTML attributes. Because attributes has many more attack vectors than output inside HTML tags.

The only way to avoid XSS attacks is to encode everything except alphanumeric characters. Escape all characters with ASCII values less than 256 with the &#xHH; format. Which unfortunately may cause problems in your scenario, if you are using CSS classes and javascript to fetch those elements.

OWASP has a good description of how to mitigate HTML attribute XSS:

http://www.owasp.org/index.php/XSS_(Cross_Site_Scripting)_Prevention_Cheat_Sheet#RULE_.233_-_JavaScript_Escape_Before_Inserting_Untrusted_Data_into_HTML_JavaScript_Data_Values

Some linux distributions have a php_mysql and php_mysqli package to install.

when curl is used to download a large file then CURLOPT_TIMEOUT is the main option you have to set for.

CURLOPT_RETURNTRANSFER has to be true in case you are getting file like pdf/csv/image etc.

You may find the further detail over here(correct url) Curl Doc

From that page:

curl_setopt($request, CURLOPT_TIMEOUT, 300); //set timeout to 5 mins

curl_setopt($request, CURLOPT_RETURNTRANSFER, true); // true to get the output as string otherwise false

As other answers stated , 'Order by' after LAST Union should apply to both datasets joined by union.

I was having two data sets but using different tables but same columns. 'Order by' after LAST Union didn't still worked. Using ALIAS for column used in 'order by' did the trick.

Select Name, Address for Employee 
Union
Select Customer_Name, Address from Customer
order by customer_name;   --Won't work

So solution is use Alias 'User_Name' :

Select Name as User_Name, Address for Employee 
Union
Select Customer_Name as User_Name, Address from Customer
order by User_Name; 

We are using Response.SetCookie() for update the old one cookies and Response.Cookies.Add() are use to add the new cookies. Here below code CompanyId is update in old cookie[OldCookieName].

HttpCookie cookie = Request.Cookies["OldCookieName"];//Get the existing cookie by cookie name.
cookie.Values["CompanyID"] = Convert.ToString(CompanyId);
Response.SetCookie(cookie); //SetCookie() is used for update the cookie.
Response.Cookies.Add(cookie); //The Cookie.Add() used for Add the cookie.

declare @MyNumber float 
set @MyNumber = 123.45 
select 'My number is ' + CAST(@MyNumber as nvarchar(max))

You will need to configure your Win7 PC as a Time Server, and then configure the RasPi to connect to it for NTP services.

Configure Win7 as authoritative time server. Configure RasPi time server lookup.

FYI: from a book and some lines adjusted because its stil valid:

Invoking SaveChanges() method begins a transaction which automatically rolls back all changes persisted to the database if an exception occurs before iteration completes; otherwise the transaction commits. You might be tempted to apply the method after each entity update or deletion rather than after iteration completes, especially when you're updating or deleting massive numbers of entities.

If you try to invoke SaveChanges() before all data has been processed, you incur a "New transaction is not allowed because there are other threads running in the session" exception. The exception occurs because SQL Server doesn't permit starting a new transaction on a connection that has a SqlDataReader open, even with Multiple Active Record Sets (MARS) enabled by the connection string (EF's default connection string enables MARS)

Sometimes its better to understand why things are happening ;-)

#include "header.h"

int estimatedPopulation (int currentPopulation, float growthRate)

    return currentPopulation + currentPopulation * growthRate  / 100;
}

SELECT * FROM people WHERE email NOT LIKE '%_@__%.__%'

Anything more complex will likely return false negatives and run slower.

Validating e-mail addresses in code is virtually impossible.

You can use functools.partial for this (as you suspected):

from functools import partial

def target(lock, iterable_item):
    for item in iterable_item:
        # Do cool stuff
        if (... some condition here ...):
            lock.acquire()
            # Write to stdout or logfile, etc.
            lock.release()

def main():
    iterable = [1, 2, 3, 4, 5]
    pool = multiprocessing.Pool()
    l = multiprocessing.Lock()
    func = partial(target, l)
    pool.map(func, iterable)
    pool.close()
    pool.join()

Example:

def f(a, b, c):
    print("{} {} {}".format(a, b, c))

def main():
    iterable = [1, 2, 3, 4, 5]
    pool = multiprocessing.Pool()
    a = "hi"
    b = "there"
    func = partial(f, a, b)
    pool.map(func, iterable)
    pool.close()
    pool.join()

if __name__ == "__main__":
    main()

Output:

hi there 1
hi there 2
hi there 3
hi there 4
hi there 5

try this:

String json = "{'phonetype':'N95','cat':'WP'}";

With MSSQL you can do something like this:

declare @result varchar(500)
set @result = ''
select @result = @result + ModuleValue + ', ' 
from TableX where ModuleId = @ModuleId

if you do it from unix command (apart from PGAdmin) dont forget to pass the DB as a parameter. otherwise this extension will not be enabled when executing requests on this DB

From the npm docs:

git://github.com/<user>/<project>.git#<branch>

git://github.com/<user>/<project>.git#feature\/<branch>

As of NPM version 1.1.65, you can do this:

<user>/<project>#<branch>

There are two ways to tackle this based on what you want:

Solution 1: Remove purple commits, preserving history (incase you want to roll back)

git revert -m 1 <SHA of merge>

-m 1 specifies which parent line to choose

Purple commits will still be there in history but since you have reverted, you will not see code from those commits.

Solution 2: Completely remove purple commits (disruptive change if repo is shared)

git rebase -i <SHA before branching out>

and delete (remove lines) corresponding to purple commits.

This would be less tricky if commits were not made after merge. Additional commits increase the chance of conflicts during revert/rebase.

A wait() only makes sense when there is also a notify(), so it's always about communication between threads, and that needs synchronization to work correctly. One could argue that this should be implicit, but that would not really help, for the following reason:

Semantically, you never just wait(). You need some condition to be satsified, and if it is not, you wait until it is. So what you really do is

if(!condition){
    wait();
}

But the condition is being set by a separate thread, so in order to have this work correctly you need synchronization.

A couple more things wrong with it, where just because your thread quit waiting doesn't mean the condition you are looking for is true:

• You can get spurious wakeups (meaning that a thread can wake up from waiting without ever having received a notification), or

• The condition can get set, but a third thread makes the condition false again by the time the waiting thread wakes up (and reacquires the monitor).

To deal with these cases what you really need is always some variation of this:

synchronized(lock){
    while(!condition){
        lock.wait();
    }
}

Better yet, don't mess with the synchronization primitives at all and work with the abstractions offered in the java.util.concurrent packages.

Typing 'my IP' in google search I got my public IP address and pasted it in IP address (the third option). It works for me.

Asus Nexus 7 on my Windows 7 64 bits computer for development purposes :

I tried to install the driver for the nexus 7 manually like explained in the official tutorial of Asus

Unfortunately, I had an error, Windows couldn't recognize the driver.

I tried to change the USB connection mode to PTP or MTP by going in the storage menu and clicking on the top right menu . In both cases, windows recognize the devices but it still didn't work in debugging mode.

The only way it worked for me is by installing : adb universal installer . I scanned it before clicking on the executable, it seems to be fine.

Using a Service Account might work for you.

Also you can try to use

@JsonSerialize(include=JsonSerialize.Inclusion.NON_NULL)

if you are dealing with jackson with version below 2+ (1.9.5) i tested it, you can easily use this annotation above the class. Not for specified for the attributes, just for class decleration.

Break out the LIKE clauses into 2 separate statements, i.e.:

(fieldname1 LIKE '%this%' or fieldname1 LIKE '%that%' ) and something=else

If none of the above answers worked for you, You can try the following solution which worked for me.

Go to Services manager(services.msc) and enable the below services and try again.

1. WLAN AutoConfig
2. Wi-Fi Direct Services Connection Manager Service

Hope this solved your problem.

CSS Triangles: A Tragedy in Five Acts

As alex said, borders of equal width butt up against each other at 45 degree angles:

When you have no top border, it looks like this:

Then you give it a width of 0...

...and a height of 0...

...and finally, you make the two side borders transparent:

That results in a triangle.

This could work but I don't know if it's convenient for your case:

@ViewChildren('contentPlaceholder', {read: ViewContainerRef}) viewContainerRefs: QueryList;

ngAfterViewInit() {
 this.viewContainerRefs.changes.subscribe(item => {
   if(this.viewContainerRefs.toArray().length) {
     // shown
   }
 })
}

The easiest way I've tackled this is with CSS:

<style>
.redUnderline {
    color: #ff0000;
    border-bottom: 1px solid #000000;
}
</style>
<span class="redUnderline">$username</span>

Also, for an actual underline, if your item is a link, this works:

<style>
a.blackUnderline {
   color: #000000;
   text-decoration: underline;
}
.red {
    color: #ff0000;
}
</style>
<a href="" class="blackUnderline"><span class="red">$username</span></a>

For your first method change ws.Range("A") to ws.Range("A:A") which will search the entirety of column a, like so:

Sub Find_Bingo()

        Dim wb As Workbook
        Dim ws As Worksheet
        Dim FoundCell As Range
        Set wb = ActiveWorkbook
        Set ws = ActiveSheet

            Const WHAT_TO_FIND As String = "Bingo"

            Set FoundCell = ws.Range("A:A").Find(What:=WHAT_TO_FIND)
            If Not FoundCell Is Nothing Then
                MsgBox (WHAT_TO_FIND & " found in row: " & FoundCell.Row)
            Else
                MsgBox (WHAT_TO_FIND & " not found")
            End If
End Sub

For your second method, you are using Bingo as a variable instead of a string literal. This is a good example of why I add Option Explicit to the top of all of my code modules, as when you try to run the code it will direct you to this "variable" which is undefined and not intended to be a variable at all.

Additionally, when you are using With...End With you need a period . before you reference Cells, so Cells should be .Cells. This mimics the normal qualifying behavior (i.e. Sheet1.Cells.Find..)

Change Bingo to "Bingo" and change Cells to .Cells

With Sheet1
        Set FoundCell = .Cells.Find(What:="Bingo", After:=.Cells(1, 1), _
        LookIn:=xlValues, lookat:=xlPart, SearchOrder:=xlByRows, _
        SearchDirection:=xlNext, MatchCase:=False, SearchFormat:=False)
    End With

If Not FoundCell Is Nothing Then
        MsgBox ("""Bingo"" found in row " & FoundCell.Row)
Else
        MsgBox ("Bingo not found")
End If

Update

In my

With Sheet1
    .....
End With

The Sheet1 refers to a worksheet's code name, not the name of the worksheet itself. For example, say I open a new blank Excel workbook. The default worksheet is just Sheet1. I can refer to that in code either with the code name of Sheet1 or I can refer to it with the index of Sheets("Sheet1"). The advantage to using a codename is that it does not change if you change the name of the worksheet.

Continuing this example, let's say I renamed Sheet1 to Data. Using Sheet1 would continue to work, as the code name doesn't change, but now using Sheets("Sheet1") would return an error and that syntax must be updated to the new name of the sheet, so it would need to be Sheets("Data").

In the VB Editor you would see something like this:

Notice how, even though I changed the name to Data, there is still a Sheet1 to the left. That is what I mean by codename.

The Data worksheet can be referenced in two ways:

Debug.Print Sheet1.Name
Debug.Print Sheets("Data").Name

Both should return Data

More discussion on worksheet code names can be found here.

The following program calculates nCr in an efficient manner (compared to calculating factorials etc.)

import operator as op
from functools import reduce

def ncr(n, r):
    r = min(r, n-r)
    numer = reduce(op.mul, range(n, n-r, -1), 1)
    denom = reduce(op.mul, range(1, r+1), 1)
    return numer // denom  # or / in Python 2

As of Python 3.8, binomial coefficients are available in the standard library as math.comb:

>>> from math import comb
>>> comb(10,3)
120

UPDATE table_name 
SET field = replace(field, 'string-to-find', 'string-that-will-replace-it');

Here's a simple little utility class that you can use to convert local date times from zone to zone, including a utility method directly to convert a local date time from the current zone to UTC (with main method so you can run it and see the results of a simple test):

import java.time.LocalDateTime;
import java.time.ZoneId;
import java.time.ZoneOffset;
import java.time.ZonedDateTime;

public final class DateTimeUtil {
    private DateTimeUtil() {
        super();
    }

    public static void main(final String... args) {
        final LocalDateTime now = LocalDateTime.now();
        final LocalDateTime utc = DateTimeUtil.toUtc(now);

        System.out.println("Now: " + now);
        System.out.println("UTC: " + utc);
    }

    public static LocalDateTime toZone(final LocalDateTime time, final ZoneId fromZone, final ZoneId toZone) {
        final ZonedDateTime zonedtime = time.atZone(fromZone);
        final ZonedDateTime converted = zonedtime.withZoneSameInstant(toZone);
        return converted.toLocalDateTime();
    }

    public static LocalDateTime toZone(final LocalDateTime time, final ZoneId toZone) {
        return DateTimeUtil.toZone(time, ZoneId.systemDefault(), toZone);
    }

    public static LocalDateTime toUtc(final LocalDateTime time, final ZoneId fromZone) {
        return DateTimeUtil.toZone(time, fromZone, ZoneOffset.UTC);
    }

    public static LocalDateTime toUtc(final LocalDateTime time) {
        return DateTimeUtil.toUtc(time, ZoneId.systemDefault());
    }
}

Try this in Swift :

var urlString = myUrl.absoluteString

Objective-C:

NSString *urlString = [myURL absoluteString];

rbind() needs the two object names to be the same. For example, the first object names: ID Age, the next object names: ID Gender,if you want to use rbind(), it will print out:

names do not match previous names

Press delete key in insert mode to remove blank lines.

For users of SQL 2000, the actual command that will provide this information is:

select c.text
from sysobjects     o
join syscomments    c on c.id = o.id
where o.name = '<view_name_here>'
  and o.type      = 'V'

From the Oracle docs:

As implied by its name, this interface models the mathematical set abstraction.

In Set Theory, "a "set" is a collection of distinct objects, considered as an object in its own right." - [Wikipedia - Set].

Mathematically, elements in sets are not individualised. Their only identity is derived from their presence in the set. Therefore, there is no point in getting the "first" element in a set, as conceptually such a task is illogical.

There may be no point to getting the "first" element from a set, but if all you need is to get one single object from a set (with no guarantees as to which object that is) you can do the following:

for(String aSiteId: siteIdSet) {
    siteId = aSiteId;
    break;
}

This is a slightly shorter way (than the method you posted) to get the "first" object of a Set, however since an Iterator is still being created (under the hood) it does not grant any performance benefit.

You can turn the color picker into an application by following the guide here:

Looks to me as MySQL 3.6 gives the following error while MySQL 3.7 no longer errors out. I am yet to find anything in the documentation regarding this fix.

While I'd generally agree that inspect is a good answer, I'd disagree that you can't get the source code of objects defined in the interpreter. If you use dill.source.getsource from dill, you can get the source of functions and lambdas, even if they are defined interactively. It also can get the code for from bound or unbound class methods and functions defined in curries... however, you might not be able to compile that code without the enclosing object's code.

>>> from dill.source import getsource
>>> 
>>> def add(x,y):
...   return x+y
... 
>>> squared = lambda x:x**2
>>> 
>>> print getsource(add)
def add(x,y):
  return x+y

If you use JAVA it's as simple as this:

Polymorphism is using inherited methods but "Overriding" them to do something different (or the same if you call super so wouldn't technically be polymorphic).

Correct me if I'm wrong.

This also works:

I just changed with this.state.color==='white'?'black':'white'.

You can also pick the color from drop-down values and update in place of 'black';

May be You are not registering the Controllers. Try below code:

Step 1. Write your own controller factory class ControllerFactory :DefaultControllerFactory by implementing defaultcontrollerfactory in models folder

  public class ControllerFactory :DefaultControllerFactory
    {
    protected override IController GetControllerInstance(RequestContext         requestContext, Type controllerType)
        {
            try
            {
                if (controllerType == null)
                    throw new ArgumentNullException("controllerType");

                if (!typeof(IController).IsAssignableFrom(controllerType))
                    throw new ArgumentException(string.Format(
                        "Type requested is not a controller: {0}",
                        controllerType.Name),
                        "controllerType");

                return MvcUnityContainer.Container.Resolve(controllerType) as IController;
            }
            catch
            {
                return null;
            }

        }
        public static class MvcUnityContainer
        {
            public static UnityContainer Container { get; set; }
        }
    }

Step 2:Regigster it in BootStrap: inBuildUnityContainer method

private static IUnityContainer BuildUnityContainer()
    {
      var container = new UnityContainer();

      // register all your components with the container here
      // it is NOT necessary to register your controllers

      // e.g. container.RegisterType<ITestService, TestService>();    
      //RegisterTypes(container);
      container = new UnityContainer();
      container.RegisterType<IProductRepository, ProductRepository>();


      MvcUnityContainer.Container = container;
      return container;
    }

Step 3: In Global Asax.

protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();

            WebApiConfig.Register(GlobalConfiguration.Configuration);
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles);
            AuthConfig.RegisterAuth();
            Bootstrapper.Initialise();
            ControllerBuilder.Current.SetControllerFactory(typeof(ControllerFactory));

        }

And you are done

Apache collections supports collate method since version 4; you can do this using the collate method in:

org.apache.commons.collections4.CollectionUtils

Here quote from javadoc:

collate(Iterable<? extends O> a, Iterable<? extends O> b, Comparator<? super O> c)

Merges two sorted Collections, a and b, into a single, sorted List such that the ordering of the elements according to Comparator c is retained.

Do not re-invent the wheel! Document reference: http://commons.apache.org/proper/commons-collections/apidocs/org/apache/commons/collections4/CollectionUtils.html

This will work:

let item = tableView.cellForRowAtIndexPath(indexPath)!.textLabel!.text!

Sharing my solution here, based on Chris' answer. Hope it can help others.

I needed to dynamically append child elements into my JSX, but in a simpler way than conditional checks in my return statement. I want to show a loader in the case that the child elements aren't ready yet. Here it is:

export class Settings extends React.PureComponent {
  render() {
    const loading = (<div>I'm Loading</div>);
    let content = [];
    let pushMessages = null;
    let emailMessages = null;

    if (this.props.pushPreferences) {
       pushMessages = (<div>Push Content Here</div>);
    }
    if (this.props.emailPreferences) {
      emailMessages = (<div>Email Content Here</div>);
    }

    // Push the components in the order I want
    if (emailMessages) content.push(emailMessages);
    if (pushMessages) content.push(pushMessages);

    return (
      <div>
        {content.length ? content : loading}
      </div>
    )
}

Now, I do realize I could also just put {pushMessages} and {emailMessages} directly in my return() below, but assuming I had even more conditional content, my return() would just look cluttered.

Sending a POST request is easy in vanilla Java. Starting with a URL, we need t convert it to a URLConnection using url.openConnection();. After that, we need to cast it to a HttpURLConnection, so we can access its setRequestMethod() method to set our method. We finally say that we are going to send data over the connection.

URL url = new URL("https://www.example.com/login");
URLConnection con = url.openConnection();
HttpURLConnection http = (HttpURLConnection)con;
http.setRequestMethod("POST"); // PUT is another valid option
http.setDoOutput(true);

We then need to state what we are going to send:

Sending a simple form

A normal POST coming from a http form has a well defined format. We need to convert our input to this format:

Map<String,String> arguments = new HashMap<>();
arguments.put("username", "root");
arguments.put("password", "sjh76HSn!"); // This is a fake password obviously
StringJoiner sj = new StringJoiner("&");
for(Map.Entry<String,String> entry : arguments.entrySet())
    sj.add(URLEncoder.encode(entry.getKey(), "UTF-8") + "=" 
         + URLEncoder.encode(entry.getValue(), "UTF-8"));
byte[] out = sj.toString().getBytes(StandardCharsets.UTF_8);
int length = out.length;

We can then attach our form contents to the http request with proper headers and send it.

http.setFixedLengthStreamingMode(length);
http.setRequestProperty("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");
http.connect();
try(OutputStream os = http.getOutputStream()) {
    os.write(out);
}
// Do something with http.getInputStream()

Sending JSON

We can also send json using java, this is also easy:

byte[] out = "{\"username\":\"root\",\"password\":\"password\"}" .getBytes(StandardCharsets.UTF_8);
int length = out.length;

http.setFixedLengthStreamingMode(length);
http.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
http.connect();
try(OutputStream os = http.getOutputStream()) {
    os.write(out);
}
// Do something with http.getInputStream()

Remember that different servers accept different content-types for json, see this question.

Sending files with java post

Sending files can be considered more challenging to handle as the format is more complex. We are also going to add support for sending the files as a string, since we don't want to buffer the file fully into the memory.

For this, we define some helper methods:

private void sendFile(OutputStream out, String name, InputStream in, String fileName) {
    String o = "Content-Disposition: form-data; name=\"" + URLEncoder.encode(name,"UTF-8") 
             + "\"; filename=\"" + URLEncoder.encode(filename,"UTF-8") + "\"\r\n\r\n";
    out.write(o.getBytes(StandardCharsets.UTF_8));
    byte[] buffer = new byte[2048];
    for (int n = 0; n >= 0; n = in.read(buffer))
        out.write(buffer, 0, n);
    out.write("\r\n".getBytes(StandardCharsets.UTF_8));
}

private void sendField(OutputStream out, String name, String field) {
    String o = "Content-Disposition: form-data; name=\"" 
             + URLEncoder.encode(name,"UTF-8") + "\"\r\n\r\n";
    out.write(o.getBytes(StandardCharsets.UTF_8));
    out.write(URLEncoder.encode(field,"UTF-8").getBytes(StandardCharsets.UTF_8));
    out.write("\r\n".getBytes(StandardCharsets.UTF_8));
}

We can then use these methods to create a multipart post request as follows:

String boundary = UUID.randomUUID().toString();
byte[] boundaryBytes = 
           ("--" + boundary + "\r\n").getBytes(StandardCharsets.UTF_8);
byte[] finishBoundaryBytes = 
           ("--" + boundary + "--").getBytes(StandardCharsets.UTF_8);
http.setRequestProperty("Content-Type", 
           "multipart/form-data; charset=UTF-8; boundary=" + boundary);

// Enable streaming mode with default settings
http.setChunkedStreamingMode(0); 

// Send our fields:
try(OutputStream out = http.getOutputStream()) {
    // Send our header (thx Algoman)
    out.write(boundaryBytes);

    // Send our first field
    sendField(out, "username", "root");

    // Send a seperator
    out.write(boundaryBytes);

    // Send our second field
    sendField(out, "password", "toor");

    // Send another seperator
    out.write(boundaryBytes);

    // Send our file
    try(InputStream file = new FileInputStream("test.txt")) {
        sendFile(out, "identification", file, "text.txt");
    }

    // Finish the request
    out.write(finishBoundaryBytes);
}


// Do something with http.getInputStream()

You might want also to have a look at jmx4perl. It provides java-less access to a remote Java EE Server's MBeans. However, a small agent servlet needs to be installed on the target platform, which provides a restful JMX Access via HTTP with a JSON payload. (Version 0.50 will add an agentless mode by implementing a JSR-160 proxy).

Advantages are quick startup times compared to launching a local java JVM and ease of use. jmx4perl comes with a full set of Perl modules which can be easily used in your own scripts:

use JMX::Jmx4Perl;
use JMX::Jmx4Perl::Alias;   # Import certains aliases for MBeans

print "Memory Used: ",
      JMX::Jmx4Perl
          ->new(url => "http://localhost:8080/j4p")
          ->get_attribute(MEMORY_HEAP_USED);

You can also use alias for common MBean/Attribute/Operation combos (e.g. for most MXBeans). For additional features (Nagios-Plugin, XPath-like access to complex attribute types, ...), please refer to the documentation of jmx4perl.

This answer is by no means exhaustive but it may explain it enough to make things click.

In virtual memory systems, there is a disconnect between logical and physical addresses.

An application can be given a virtual address space of (let's say) 4G. This is its usable memory and it's free to use it as it sees fit. It's a nice contiguous block of memory (from the point of view of the application).

However, it is not the only application running, and the OS has to mediate between them all. Underneath that nice contiguous model, there is a lot of mapping going on to convert logical to physical addresses.

With this mapping, the OS and hardware (I'll just call these the lower layers from here on in) is free to put the application pages anywhere it wants (either in physical memory or swapped out to secondary storage).

When the application tries to access memory at logical address 50, the lower levels can translate that to a physical address using translation tables. And, if it tries to access logical memory that's been swapped out to disk, a page fault is raised and the lower levels can bring the relevant data back into memory, at whatever physical address it wants.

In the bad old days when physical addresses were all you had, code had to be relocatable (or fixed up on load) since it could load anywhere. With virtual memory, that code (and data) can be at logical memory location 50 in a dozen different processes at the same time - it's actual physical address will be different however.

It can even be shared so that one physical copy exists in the address space of many processes at once. This is the crux of shared code (so we don't use more physical memory than we need) and shared memory to allow easy inter-process communication).

It is, of course, less efficient than a pure physical-address environment but the CPU manufacturers try to make it as insanely efficient as possible, since it's used heavily. The advantages far outweigh the disadvantages.

the Correct Solution Would be like this

   QString k;
   k = "CRAZYYYQT";
   char ab[16];
   sprintf(ab,"%s",(const char *)((QByteArray)(k.toLatin1()).data()) );
   sprintf(ab,"%s",(const char *)((QByteArray)(k.toStdString()).data()));  
   sprintf(ab,"%s",(const char *)k.toStdString().c_str()  );
   qDebug()<<"--->"<<ab<<"<---";

To solve a similar problem i used iTextSharp like this:

//Create the document which will contain the combined PDF's
Document document = new Document();

//Create a writer for de document
PdfCopy writer = new PdfCopy(document, new FileStream(OutPutFilePath, FileMode.Create));
if (writer == null)
{
     return;
}

//Open the document
document.Open();

//Get the files you want to combine
string[] filePaths = Directory.GetFiles(DirectoryPathWhereYouHaveYourFiles);
foreach (string filePath in filePaths)
{
     //Read the PDF file
     using (PdfReader reader = new PdfReader(vls_FilePath))
     {
         //Add the file to the combined one
         writer.AddDocument(reader);
     }
}

//Finally close the document and writer
writer.Close();
document.Close();

Resolved answer: To copy a directory's content to another directory I use the next:

- name: copy consul_ui files
  command: cp -r /home/{{ user }}/dist/{{ item }} /usr/share/nginx/html
  with_items:
   - "index.html"
   - "static/"

It copies both items to the other directory. In the example, one of the items is a directory and the other is not. It works perfectly.

If s is your string:

s.replace(/^[^(]*\(/, "") // trim everything before first parenthesis
 .replace(/\)[^(]*$/, "") // trim everything after last parenthesis
 .split(/\)[^(]*\(/);      // split between parenthesis

One of the nice things about lambda that's in my opinion understated is that it's way of deferring an evaluation for simple forms till the value is needed. Let me explain.

Many library routines are implemented so that they allow certain parameters to be callables (of whom lambda is one). The idea is that the actual value will be computed only at the time when it's going to be used (rather that when it's called). An (contrived) example might help to illustrate the point. Suppose you have a routine which which was going to do log a given timestamp. You want the routine to use the current time minus 30 minutes. You'd call it like so

log_timestamp(datetime.datetime.now() - datetime.timedelta(minutes = 30))

Now suppose the actual function is going to be called only when a certain event occurs and you want the timestamp to be computed only at that time. You can do this like so

log_timestamp(lambda : datetime.datetime.now() - datetime.timedelta(minutes = 30))

Assuming the log_timestamp can handle callables like this, it will evaluate this when it needs it and you'll get the timestamp at that time.

There are of course alternate ways to do this (using the operator module for example) but I hope I've conveyed the point.

Update: Here is a slightly more concrete real world example.

Update 2: I think this is an example of what is called a thunk.

Installation of multiple versions of Python and respective Packages.

Python version on the same windows machine : 2.7 , 3.4 and 3.6

Installation of all 3 versions of Python :

• Installed the Python 2.7 , 3.4 and 3.6 with the below paths

PATH for all 3 versions of Python :

• Made sure the PATH variable ( in System Variables ) has below paths included - C:\Python27\;C:\Python27\Scripts;C:\Python34\;C:\Python34\Scripts;C:\Python36\;C:\Python36\Scripts\;

Renaming the executables for versions :

• Changed the python executable name in C:\Python36 and C:\Python34 to python36 and python34 respectively.

Checked for the command prompt with all versions :

Installing the packages separately for each version

We have open-sourced our lightweight async REST client library for Android, you might find it useful if you have minimal requirements and don't want to handle the multithreading yourself - it is very OK for basic communications but not a full-blown REST client library.

It's called libRESTfulClient and can be found on GitHub.

Amazon S3 does not have folders/directories. It is a flat file structure.

To maintain the appearance of directories, path names are stored as part of the object Key (filename). For example:

• images/foo.jpg

In this case, the whole Key is images/foo.jpg, rather than just foo.jpg.

I suspect that your problem is that boto is returning a file called my_folder/.8Df54234 and is attempting to save it to the local filesystem. However, your local filesystem interprets the my_folder/ portion as a directory name, and that directory does not exist on your local filesystem.

You could either truncate the filename to only save the .8Df54234 portion, or you would have to create the necessary directories before writing files. Note that it could be multi-level nested directories.

An easier way would be to use the AWS Command-Line Interface (CLI), which will do all this work for you, eg:

aws s3 cp --recursive s3://my_bucket_name local_folder

There's also a sync option that will only copy new and modified files.

If you want to print the array like you print a 2D list in Python:

#include <stdio.h>

int main()
{
  int i, j;
  int my_array[3][3] = {{10, 23, 42}, {1, 654, 0}, {40652, 22, 0}};
  for(i = 0; i < 3; i++)
  {
      if (i == 0) {
          printf("[");
      }
      printf("[");
      for(j = 0; j < 3; j++)
      {
         printf("%d", my_array[i][j]);
         if (j < 2) {
             printf(", ");
         }
      }
    printf("]");
    if (i == 2) {
        printf("]");
    }

    if (i < 2) {
        printf(", ");
    }
  }
  return 0;
}

Output will be:

[[10, 23, 42], [1, 654, 0], [40652, 22, 0]]

You can use <i [className]="'fa fa-' + data?.icon"> </i>

Somewhat OT: If you're using Rails, the standard formatting of webpages may be different. For data entry forms text boxes are scrollable, but character varying (Rails string) boxes are one-line. Show views are as long as needed.

Simple steps to get this done:

1. Start from keychain (which contains your dev key already) on your computer and create a request for certificate. Upload the request to dev site and create the certificate.
2. Create a profile using the certificate.
3. Download the profile and drop it on Xcode.

Now all the dots are connected and it should work. This works for both dev and distribution.

If your application uses async stuff and you're fiddling with Mouse's cursor, you probably want to do it only in main UI thread. You can use app's Dispatcher thread for that:

Application.Current.Dispatcher.Invoke(() =>
{
    // The check is required to prevent cursor flickering
    if (Mouse.OverrideCursor != cursor)
        Mouse.OverrideCursor = cursor;
});

Well, to start with List<T> does have the FindAll and ConvertAll methods - but the more idiomatic, modern approach is to use LINQ:

// Find all the people older than 30
var query1 = list.Where(person => person.Age > 30);

// Find each person's name
var query2 = list.Select(person => person.Name);

You'll need a using directive in your file to make this work:

using System.Linq;

Note that these don't use strings to express predicates and projects - they use delegates, usually created from lambda expressions as above.

If lambda expressions and LINQ are new to you, I would suggest you get a book covering LINQ first, such as LINQ in Action, Pro LINQ, C# 4 in a Nutshell or my own C# in Depth. You certainly can learn LINQ just from web tutorials, but I think it's such an important technology, it's worth taking the time to learn it thoroughly.

Using ArrayUtils.removeElement(Object[],Object) from org.apache.commons.lang is by far the easiest way to do this.

int[] numbers = {1,2,3,4,5,6,7};
//removing number 1
numbers =(int[])ArrayUtils.removeElement(numbers, 1);

GetType() exists on every single framework type, because it is defined on the base object type. So, regardless of the type itself, you can use it to return the underlying Type

So, all you need to do is:

u.GetType() == t

I would use $_POST, and $_GET because differently from $_REQUEST their content is not influenced by variables_order.
When to use $_POST and $_GET depends on what kind of operation is being executed. An operation that changes the data handled from the server should be done through a POST request, while the other operations should be done through a GET request. To make an example, an operation that deletes a user account should not be directly executed after the user click on a link, while viewing an image can be done through a link.

Your class doesn't have a __init__(), so by the time it's instantiated, the attribute atoms is not present. You'd have to do C.setdata('something') so C.atoms becomes available.

>>> C = Residues()
>>> C.atoms.append('thing')

Traceback (most recent call last):
  File "<pyshell#84>", line 1, in <module>
    B.atoms.append('thing')
AttributeError: Residues instance has no attribute 'atoms'

>>> C.setdata('something')
>>> C.atoms.append('thing')   # now it works
>>> 

Unlike in languages like Java, where you know at compile time what attributes/member variables an object will have, in Python you can dynamically add attributes at runtime. This also implies instances of the same class can have different attributes.

To ensure you'll always have (unless you mess with it down the line, then it's your own fault) an atoms list you could add a constructor:

def __init__(self):
    self.atoms = []

If you are popping it in the DOM then try wrapping it in

<pre>
    <code>{JSON.stringify(REPLACE_WITH_OBJECT, null, 4)}</code>
</pre>

makes a little easier to visually parse.

There is no :unchecked pseudo class however if you use the :checked pseudo class and the sibling selector you can differentiate between both states. I believe all of the latest browsers support the :checked pseudo class, you can find more info from this resource: http://www.whatstyle.net/articles/18/pretty_form_controls_with_css

Your going to get better browser support with jquery... you can use a click function to detect when the click happens and if its checked or not, then you can add a class or remove a class as necessary...

yourEnumList.Select(s => (int)s).ToList()

A variable used in lambda expression should be a final or effectively final, but you can assign a value to a final one element array.

private TimeZone extractCalendarTimeZoneComponent(Calendar cal, TimeZone calTz) {
    try {
        TimeZone calTzLocal[] = new TimeZone[1];
        calTzLocal[0] = calTz;
        cal.getComponents().get("VTIMEZONE").forEach(component -> {
            TimeZone v = component;
            v.getTimeZoneId();
            if (calTzLocal[0] == null) {
                calTzLocal[0] = TimeZone.getTimeZone(v.getTimeZoneId().getValue());
            }
        });
    } catch (Exception e) {
        log.warn("Unable to determine ical timezone", e);
    }
    return null;
}

Python 2:

• raw_input() takes exactly what the user typed and passes it back as a string.

• input() first takes the raw_input() and then performs an eval() on it as well.

The main difference is that input() expects a syntactically correct python statement where raw_input() does not.

Python 3:

• raw_input() was renamed to input() so now input() returns the exact string.
• Old input() was removed.

If you want to use the old input(), meaning you need to evaluate a user input as a python statement, you have to do it manually by using eval(input()).

You can use this

string.strip().split(":")

I wanted to add a concrete example to accompany the other answers

You need to specify the name of the class that you want to test, so if you have the following project (this is a Play project):

You can test just the Login tests by running the following command from the SBT console:

test:testOnly *LoginServiceSpec

If you are running the command from outside the SBT console, you would do the following:

sbt "test:testOnly *LoginServiceSpec"

In my case, the error "BeanFactory not initialized or already closed - call 'refresh' before" was a consequence of a previous error that I didn't noticed in the server startup. I think that it is not always the real cause of the problem.

I had the same issue and did all the tips including Gmail setting (e.g. less secure apps access) with no luck. But finally when I changed password to something different, for some reason it worked! FYI, the initial password did not have any special characters.

If you are using archlinux or Ubuntu just type the commands below:

cd /opt/lampp/phpmyadmin

then

sudo gedit config.inc.php

Then when you access the file look for the scripts below,

//$cfg['Servers'][$i]['host'] ='localhost'

remove '//' so that it remains as shown below:

$cfg['Servers'][$i]['host'] ='localhost'

Then change the 'localhost' to '127.0.0.1' and the script should turn as shown below:

$cfg['Servers'][$i]['host'] ='127.0.0.1'

Get back to your browser and type http://127.0.0.1/phpmyadmin/

If it is still refusing

You should check the host, username and password in your configuration and make sure that they correspond to the information given by the administrator of the MySQL server.

so then get back to the same file config.inc.php you were editing and do as follows:

cd /opt/lampp/phpmyadmin

then

sudo gedit config.inc.php

search for the script below

$cfg['Servers'][$i]['password'] =''

Fill the password with your root password

$cfg['Servers'][$i]['password'] ='your_password'

And it should work.

You're correct that this is really painful to hand out to others, but if you have to, this is how you do it.

1. Just extract the .ocx file from the .cab file (it is similar to a zip)
2. Copy to the system folder (c:\windows\sysWOW64 for 64 bit systems and c:\windows\system32 for 32 bit)
3. Use regsvr32 through the command prompt to register the file (e.g. "regsvr32 c:\windows\sysWOW64\mscomct2.ocx")

<li><a href="#">[^\n]+

And replace with:

$0</a>

Where $0 is the whole match. The exact semantics will depend on the language are you using though.

WARNING: You should avoid parsing HTML with regex. Here's why.

If you are looking to break through the 2^32 barrier then try this method:

/// <summary>
/// Generate a BigInteger given a Guid. Returns a number from 0 to 2^128
/// 0 to 340,282,366,920,938,463,463,374,607,431,768,211,456
/// </summary>
    public BigInteger GuidToBigInteger(Guid guid)
    {
        BigInteger l_retval = 0;
        byte[] ba = guid.ToByteArray();
        int i = ba.Count();
        foreach (byte b in ba)
        {
            l_retval += b * BigInteger.Pow(256, --i);
        }
        return l_retval;
    }

The universe will decay to a cold and dark expanse before you experience a collision.

I have the same problem.... I change my project name and i have this problem...my solution was the checking project refences and use / in my web.xml (instead of /*)

In the page file:

<script type="text/javascript">
    var a = eval('[<% =string.Join(", ", numbers) %>]');
</script>

while in code behind:

public int[] numbers = WhatEverGetTheArray();

Funny enough, while the following code will correct the WIDTH scroll bar:

.gm-style-iw
{
    overflow: hidden !important;
    line-height: 1.35;

}

It took this to correct the HEIGHT scroll bar:

    .gm-style-iw div
    {
        overflow: hidden !important;
    }

EDIT: Adding white-space: nowrap; to either style might correct the spacing issue that seems to linger when the scroll bars are removed. Great point Nathan.

try this.. i had the same issue, below implementation worked for me

Reader reader = Files.newBufferedReader(Paths.get(<yourfilewithpath>), StandardCharsets.ISO_8859_1);

then use Reader where ever you want.

foreg:

CsvToBean<anyPojo> csvToBean = null;
    try {
        Reader reader = Files.newBufferedReader(Paths.get(csvFilePath), 
                        StandardCharsets.ISO_8859_1);
        csvToBean = new CsvToBeanBuilder(reader)
                .withType(anyPojo.class)
                .withIgnoreLeadingWhiteSpace(true)
                .withSkipLines(1)
                .build();

    } catch (IOException e) {
        e.printStackTrace();
    }

You may also try the Default encoding, which uses the current system's ANSI codepage.

StreamReader reader = new StreamReader(inputFilePath, Encoding.Default, true)

When you try using the Notepad "Save As" menu with the original file, look at the encoding combo box. It will tell you which encoding notepad guessed is used by the file.

Also, if it is an ANSI file, the detectEncodingFromByteOrderMarks parameter will probably not help much.

You should use something like this:

<div style="text-align:center">  
    <input type="submit" />  
</div>  

Or you could use something like this. By giving the element a width and specifying auto for the left and right margins the element will center itself in its parent.

<input type="submit" style="width: 300px; margin: 0 auto;" />

Based on the above answer I've written a small extension class to work with CSS and JS files:

public static class TimestampedContentExtensions
{
    public static string VersionedContent(this UrlHelper helper, string contentPath)
    {
        var context = helper.RequestContext.HttpContext;

        if (context.Cache[contentPath] == null)
        {
            var physicalPath = context.Server.MapPath(contentPath);
            var version = @"v=" + new FileInfo(physicalPath).LastWriteTime.ToString(@"yyyyMMddHHmmss");

            var translatedContentPath = helper.Content(contentPath);

            var versionedContentPath =
                contentPath.Contains(@"?")
                    ? translatedContentPath + @"&" + version
                    : translatedContentPath + @"?" + version;

            context.Cache.Add(physicalPath, version, null, DateTime.Now.AddMinutes(1), TimeSpan.Zero,
                CacheItemPriority.Normal, null);

            context.Cache[contentPath] = versionedContentPath;
            return versionedContentPath;
        }
        else
        {
            return context.Cache[contentPath] as string;
        }
    }
}

Instead of writing something like:

<link href="@Url.Content(@"~/Content/bootstrap.min.css")" rel="stylesheet" type="text/css" />
<script src="@Url.Content(@"~/Scripts/bootstrap.min.js")"></script>

You can now write:

<link href="@Url.VersionedContent(@"~/Content/bootstrap.min.css")" rel="stylesheet" type="text/css" />
<script src="@Url.VersionedContent(@"~/Scripts/bootstrap.min.js")"></script>

I.e. simply replace Url.Content with Url.VersionedContent.

Generated URLs look something like:

<link href="/Content/bootstrap.min.css?v=20151104105858" rel="stylesheet" type="text/css" />
<script src="/Scripts/bootstrap.min.js?v=20151029213517"></script>

If you use the extension class you might want to add error handling in case the MapPath call doesn't work, since contentPath isn't a physical file.

File mode, write and binary. Since you are writing a .jpg file, it looks fine.

But if you supposed to read that jpg file you need to use 'rb'

More info

On Windows, 'b' appended to the mode opens the file in binary mode, so there are also modes like 'rb', 'wb', and 'r+b'. Python on Windows makes a distinction between text and binary files; the end-of-line characters in text files are automatically altered slightly when data is read or written. This behind-the-scenes modification to file data is fine for ASCII text files, but it’ll corrupt binary data like that in JPEG or EXE files.

Well, it's fairly easy to do this with simple arithmetic and string operations:

public static List<String> splitEqually(String text, int size) {
    // Give the list the right capacity to start with. You could use an array
    // instead if you wanted.
    List<String> ret = new ArrayList<String>((text.length() + size - 1) / size);

    for (int start = 0; start < text.length(); start += size) {
        ret.add(text.substring(start, Math.min(text.length(), start + size)));
    }
    return ret;
}

I don't think it's really worth using a regex for this.

EDIT: My reasoning for not using a regex:

• This doesn't use any of the real pattern matching of regexes. It's just counting.
• I suspect the above will be more efficient, although in most cases it won't matter
• If you need to use variable sizes in different places, you've either got repetition or a helper function to build the regex itself based on a parameter - ick.
• The regex provided in another answer firstly didn't compile (invalid escaping), and then didn't work. My code worked first time. That's more a testament to the usability of regexes vs plain code, IMO.

GitHub recently introduced a new feature called Projects. This provides a visual board that is typical of many Project Management tools:

A Repository as documented on GitHub:

A repository is the most basic element of GitHub. They're easiest to imagine as a project's folder. A repository contains all of the project files (including documentation), and stores each file's revision history. Repositories can have multiple collaborators and can be either public or private.

A Project as documented on GitHub:

Project boards on GitHub help you organize and prioritize your work. You can create project boards for specific feature work, comprehensive roadmaps, or even release checklists. With project boards, you have the flexibility to create customized workflows that suit your needs.

Part of the confusion is that the new feature, Projects, conflicts with the overloaded usage of the term project in the documentation above.

You can do it via ODBC. The steps to do it:

1. Install IBM SPSS Statistics Data File Driver. Standalone Driver is enough.
2. Create DNS via ODBC manager.
3. Use the data importer in Excel via ODBC by selecting created DNS.

1.You don't need the @ prefix for attribute names any more:

http://api.jquery.com/category/selectors/attribute-selectors/:

Note: In jQuery 1.3 [@attr] style selectors were removed (they were previously deprecated in jQuery 1.2). Simply remove the ‘@’ symbol from your selectors in order to make them work again.

2.Your selector queries radio buttons by name, but that attribute is not defined in your HTML structure.

As I discovered having followed the advice in the answers given so far, you can get exceptions occuring without error messages being set, so to catch all problems you really need to get both the ErrorMessage and the Exception.

String messages = String.Join(Environment.NewLine, ModelState.Values.SelectMany(v => v.Errors)
                                                           .Select( v => v.ErrorMessage + " " + v.Exception));

or as an extension method

public static IEnumerable<String> GetErrors(this ModelStateDictionary modelState)
{
      return modelState.Values.SelectMany(v => v.Errors)
                              .Select( v => v.ErrorMessage + " " + v.Exception).ToList();

}

"start" is a name of a script, in npm you run scripts like this npm run scriptName, npm start is also a short for npm run start

As for "react-scripts" this is a script related specifically to create-react-app

Client side code: I had a requirement where my nodejs webserver should work as both server as well as client, so i added below code when i need it as client, It should work fine, i am using it and working fine for me!!!

const socket = require('socket.io-client')('http://192.168.0.8:5000', {
            reconnection: true,
            reconnectionDelay: 10000
          });
    
        socket.on('connect', (data) => {
            console.log('Connected to Socket');
        });
        
        socket.on('event_name', (data) => {
            console.log("-----------------received event data from the socket io server");
        });
    
        //either 'io server disconnect' or 'io client disconnect'
        socket.on('disconnect', (reason) => {
            console.log("client disconnected");
            if (reason === 'io server disconnect') {
              // the disconnection was initiated by the server, you need to reconnect manually
              console.log("server disconnected the client, trying to reconnect");
              socket.connect();
            }else{
                console.log("trying to reconnect again with server");
            }
            // else the socket will automatically try to reconnect
          });
    
        socket.on('error', (error) => {
            console.log(error);
        });

Here is the complete method for converting InputStream into String without using any third party library. Use StringBuilder for single threaded environment otherwise use StringBuffer.

public static String getString( InputStream is) throws IOException {
    int ch;
    StringBuilder sb = new StringBuilder();
    while((ch = is.read()) != -1)
        sb.append((char)ch);
    return sb.toString();
}

Simple & Best way:

onclick="parentNode.remove()"

Deletes the complete parent from html

System.ArgumentNullException: Value cannot be null. Parameter name: value

This error message is not very helpful!

You can get this error in many different ways. The error may not always be with the parameter name: value. It could be whatever parameter name is being passed into a function.

As a generic way to solve this, look at the stack trace or call stack:

Test method GetApiModel threw exception: 
System.ArgumentNullException: Value cannot be null.
Parameter name: value
    at Newtonsoft.Json.JsonConvert.DeserializeObject(String value, Type type, JsonSerializerSettings settings)

You can see that the parameter name value is the first parameter for DeserializeObject. This lead me to check my AutoMapper mapping where we are deserializing a JSON string. That string is null in my database.

You can change the code to check for null.

It's best practice only to escape the quotes when you need to - if you can get away without escaping it, then do!

The only times you should need to escape are when trying to put " inside a string, or ' in a character:

String quotes = "He said \"Hello, World!\"";
char quote = '\'';

Nornally the tag is used for that, with a change in style.

Like <p>This is my text <span class="highlight"> and these words are different</span></p>,

You set the css in the header (or rather, in a separate css file) to make your "highlight" text assume the color you wish.

(e.g.: with

<style type="text/css">
  .highlight {color: orange}

</style>

in the header. Avoid using the tag <font /> for that at all costs. :-)

You can delete all the documents from a collection in MongoDB, you can use the following:

db.users.remove({})

Alternatively, you could use the following method as well:

db.users.deleteMany({})

Follow the following MongoDB documentation, for further details.

To remove all documents from a collection, pass an empty filter document {} to either the db.collection.deleteMany() or the db.collection.remove() method.

If I'm understanding the type of window you're talking about, wouldn't $(window).unload() (for the dialog window) give you the hook you need?

(And if I misunderstood, and you're talking about a dialog box made via CSS rather than a pop-up browser window, then all the ways of closing that window are elements you could register click handers for.)

Edit: Ah, I see now you're talking about jquery-ui dialogs, which are made via CSS. You can hook the X which closes the window by registering a click handler for the element with the class ui-dialog-titlebar-close.

More useful, perhaps, is you tell you how to figure that out quickly. While displaying the dialog, just pop open FireBug and Inspect the elements that can close the window. You'll instantly see how they are defined and that gives you what you need to register the click handlers.

So to directly answer your question, I believe the answer is really "no" -- there's isn't a close event you can hook, but "yes" -- you can hook all the ways to close the dialog box fairly easily and get what you want.

The accepted solution (from @charles bailey) is highly dangerous if you are working in a shared repo.

As a best practice, all commits pushed to a remote repo that is shared should be considered 'immutable'. Use 'git revert' instead: http://www.kernel.org/pub/software/scm/git/docs/user-manual.html#fixing-mistakes

https://git-scm.com/book/be/v2/Git-Basics-Undoing-Things

TL;DR version: remote-tracking branch origin/master used to exist, but does not now, so local branch source is tracking something that does not exist, which is suspicious at best—it means a different Git feature is unable to do anything for you—and Git is warning you about it. You have been getting along just fine without having the "upstream tracking" feature work as intended, so it's up to you whether to change anything.

For another take on upstream settings, see Why do I have to "git push --set-upstream origin <branch>"?

This warning is a new thing in Git, appearing first in Git 1.8.5. The release notes contain just one short bullet-item about it:

• "git branch -v -v" (and "git status") did not distinguish among a branch that is not based on any other branch, a branch that is in sync with its upstream branch, and a branch that is configured with an upstream branch that no longer exists.

To describe what it means, you first need to know about "remotes", "remote-tracking branches", and how Git handles "tracking an upstream". (Remote-tracking branches is a terribly flawed term—I've started using remote-tracking names instead, which I think is a slight improvement. Below, though, I'll use "remote-tracking branch" for consistency with Git documentation.)

Each "remote" is simply a name, like origin or octopress in this case. Their purpose is to record things like the full URL of the places from which you git fetch or git pull updates. When you use git fetch remote,¹ Git goes to that remote (using the saved URL) and brings over the appropriate set of updates. It also records the updates, using "remote-tracking branches".

A "remote-tracking branch" (or remote-tracking name) is simply a recording of a branch name as-last-seen on some "remote". Each remote is itself a Git repository, so it has branches. The branches on remote "origin" are recorded in your local repository under remotes/origin/. The text you showed says that there's a branch named source on origin, and branches named 2.1, linklog, and so on on octopress.

(A "normal" or "local" branch, of course, is just a branch-name that you have created in your own repository.)

Last, you can set up a (local) branch to "track" a "remote-tracking branch". Once local branch L is set to track remote-tracking branch R, Git will call R its "upstream" and tell you whether you're "ahead" and/or "behind" the upstream (in terms of commits). It's normal (even recommend-able) for the local branch and remote-tracking branches to use the same name (except for the remote prefix part), like source and origin/source, but that's not actually necessary.

And in this case, that's not happening. You have a local branch source tracking a remote-tracking branch origin/master.

You're not supposed to need to know the exact mechanics of how Git sets up a local branch to track a remote one, but they are relevant below, so I'll show how this works. We start with your local branch name, source. There are two configuration entries using this name, spelled branch.source.remote and branch.source.merge. From the output you showed, it's clear that these are both set, so that you'd see the following if you ran the given commands:

$ git config --get branch.source.remote
origin
$ git config --get branch.source.merge
refs/heads/master

Putting these together,² this tells Git that your branch source tracks your "remote-tracking branch", origin/master.

But now look at the output of git branch -a, which shows all the local and remote-tracking branch names in your repository. The remote-tracking names are listed under remotes/ ... and there is no remotes/origin/master. Presumably there was, at one time, but it's gone now.

Git is telling you that you can remove the tracking information with --unset-upstream. This will clear out both branch.source.origin and branch.source.merge, and stop the warning.

It seems fairly likely that what you want, though, is to switch from tracking origin/master, to tracking something else: probably origin/source, but maybe one of the octopress/ names.

You can do this with git branch --set-upstream-to,³ e.g.:

$ git branch --set-upstream-to=origin/source

(assuming you're still on branch "source", and that origin/source is the upstream you want—there is no way for me to tell which one, if any, you actually want, though).

(See also How do you make an existing Git branch track a remote branch?)

I think the way you got here is that when you first did a git clone, the thing you cloned-from had a branch master. You also had a branch master, which was set to track origin/master (this is a normal, standard setup for git). This meant you had branch.master.remote and branch.master.merge set, to origin and refs/heads/master. But then your origin remote changed its name from master to source. To match, I believe you also changed your local name from master to source. This changed the names of your settings, from branch.master.remote to branch.source.remote and from branch.master.merge to branch.source.merge ... but it left the old values, so branch.source.merge was now wrong.

It was at this point that the "upstream" linkage broke, but in Git versions older than 1.8.5, Git never noticed the broken setting. Now that you have 1.8.5, it's pointing this out.

That covers most of the questions, but not the "do I need to fix it" one. It's likely that you have been working around the broken-ness for years now, by doing git pull remote branch (e.g., git pull origin source). If you keep doing that, it will keep working around the problem—so, no, you don't need to fix it. If you like, you can use --unset-upstream to remove the upstream and stop the complaints, and not have local branch source marked as having any upstream at all.

The point of having an upstream is to make various operations more convenient. For instance, git fetch followed by git merge will generally "do the right thing" if the upstream is set correctly, and git status after git fetch will tell you whether your repo matches the upstream one, for that branch.

If you want the convenience, re-set the upstream.

¹git pull uses git fetch, and as of Git 1.8.4, this (finally!) also updates the "remote-tracking branch" information. In older versions of Git, the updates did not get recorded in remote-tracking branches with git pull, only with git fetch. Since your Git must be at least version 1.8.5 this is not an issue for you.

²Well, this plus a configuration line I'm deliberately ignoring that is found under remote.origin.fetch. Git has to map the "merge" name to figure out that the full local name for the remote-branch is refs/remotes/origin/master. The mapping almost always works just like this, though, so it's predictable that master goes to origin/master.

³Or, with git config. If you just want to set the upstream to origin/source the only part that has to change is branch.source.merge, and git config branch.source.merge refs/heads/source would do it. But --set-upstream-to says what you want done, rather than making you go do it yourself manually, so that's a "better way".

GET CURRENT UTC TIME IN REQUIRED FORMAT

// Current UTC time
        OffsetDateTime utc = OffsetDateTime.now(ZoneOffset.UTC);

        // GET LocalDateTime 
        LocalDateTime localDateTime = utc.toLocalDateTime();
        System.out.println("*************" + localDateTime);

        // formated UTC time
        DateTimeFormatter dTF = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm");
        System.out.println(" formats as " + dTF.format(localDateTime));

        //GET UTC time for current date
        Date now= new Date();
        LocalDateTime utcDateTimeForCurrentDateTime = Instant.ofEpochMilli(now.getTime()).atZone(ZoneId.of("UTC")).toLocalDateTime();
        DateTimeFormatter dTF2 = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm");
        System.out.println(" formats as " + dTF2.format(utcDateTimeForCurrentDateTime));

If you know the format use strptime because strtotime does a guess for the format, which might not always be correct. Since strptime is not implemented in Windows there is a custom function

• http://nl3.php.net/manual/en/function.strptime.php#86572

Remember that the returnvalue tm_year is from 1900! and tm_month is 0-11

Example:

$a = strptime('22-09-2008', '%d-%m-%Y');
$timestamp = mktime(0, 0, 0, $a['tm_mon']+1, $a['tm_mday'], $a['tm_year']+1900)

Create a simple hash function and some linked lists of structures , depending on the hash , assign which linked list to insert the value in . Use the hash for retrieving it as well .

I did a simple implementation some time back :

...
#define K 16 // chaining coefficient

struct dict
{
    char *name; /* name of key */
    int val;   /*  value */
    struct dict *next; /* link field */
};

typedef struct dict dict;
dict *table[K];
int initialized = 0;


void  putval ( char *,int);

void init_dict()
{   
    initialized = 1;
    int i;  
    for(i=0;iname = (char *) malloc (strlen(key_name)+1);
    ptr->val = sval;
    strcpy (ptr->name,key_name);


    ptr->next = (struct dict *)table[hsh];
    table[hsh] = ptr;

}


int getval ( char *key_name )
{   
    int hsh = hash(key_name);   
    dict *ptr;
    for (ptr = table[hsh]; ptr != (dict *) 0;
        ptr = (dict *)ptr->next)
    if (strcmp (ptr->name,key_name) == 0)
        return ptr->val;
    return -1;
}

Do you mean that, in browsers that support it, word-wrap: break-word does not work ?

If included in the body definition of the stylesheet, it should works throughout the entire document.

If overflow is not a good solution, only a custom javascript could artificially break up long word.

Note: there is also this <wbr> Word Break tag. This gives the browser a spot where it can split the line up. Unfortunately, the <wbr> tag doesn't work in all browsers, only Firefox and Internet Explorer (and Opera with a CSS trick).

This is the Kotlin way:

In fragment_map.xml you should have:

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

In your MapFragment.kt you should have:

    private fun setupMap() {
        (childFragmentManager.findFragmentById(R.id.map) as SupportMapFragment?)!!.getMapAsync(this)
    }

Call setupMap() in onCreateView.

If you only need to add one path per configuration (debug/release), you could set the debug command working directory:

Project | Properties | Select Configuration | Configuration Properties | Debugging | Working directory

Repeat for each project configuration.

You could do this but it is hacky

.application-title {
   background:url("/path/to/image.png");
   /* set these dims according to your image size */
   width:500px;
   height:500px;
}

.application-title img {
   display:none;
}

Here is a working example:

I tried ScottF VB solution and got it to work. However I wanted to convert a multi-tab(workbook) excel file into a single .csv file.

This did not work, only one tab(the one that is highlighted when I open it via excel) got copied.

Is any one aware of a script that can convert a multi-tab excel file into a single .csv file?

Not to necro but I made this which can determine pixels based on a variety of values:

$.fn.extend({

    var original = value;
    var outer = property.indexOf('left') != -1 || property.indexOf('right') != -1 
      ? $(this).parent().outerWidth()
      : $(this).parent().outerHeight();

    // EM Conversion Factor
    base = base || 16;

    if (value == 'auto' || value == 'inherit') 
        return outer || 0;

    value = value.replace('rem', '');
    value = value.replace('em', '');

    if (value !== original) {
       value = parseFloat(value);
       return value ? base * value : 0;
    }

    value = value.replace('pt', '');

    if (value !== original) {
       value = parseFloat(value);
       return value ? value * 1.333333 : 0; // 1pt = 1.333px
    }

    value = value.replace('%', '');

    if (value !== original) {
      value = parseFloat(value);
      return value ? (outer * value / 100) : 0;
    }

    value = value.replace('px', '');
    return parseFloat(value) || 0;
  }
});

This way, we take into account for sizing, and auto / inherit.

Mind you that this is a highly opinion based question, so I stopped making fjords and made a quick table

Now library comparison is hard because on many parameters, all the four pretty much do the same thing, except possibly for Fresco because there is a whole bunch of new memory level optimizations in it.So let me know if certain parameters you'd like to see a comparison for based on my experience.

Having used Fresco the least, the answer might evolve as I continue to use and understand it for current exploits. The used personally is having used the library atleast once in a completed app.

*Note - Fresco now supports GIF as well as WebP animations

Go to that directory/folder and then click on the setting. In the section of "Repository name" simply rename it.

It's probably worth mentioning that for http/https some people proxy their browser traffic through Burp/ZAP or another intercepting "attack proxy". A thread that covers options for this on Android devices can be found here: https://android.stackexchange.com/questions/32366/which-browser-does-support-proxies

total count the documents where the value of the field is not equal to the specified value.

async function getRegisterUser() {
    return Login.count({"role": { $ne: 'Super Admin' }}, (err, totResUser) => {
        if (err) {
            return err;
        }
        return totResUser;
    })
}

To overcome this issue try the following. Worked for me.

Add following dependency in the pom.xml

<dependency>
  <groupId>org.glassfish.jersey.media</groupId>
  <artifactId>jersey-media-json-jackson</artifactId>
  <version>2.25</version>
</dependency>

And make sure Model class contains no arg constructor

 public Student()
    {
    }

If you are using Eclipse,

1. Open "Git Repositories"
2. Find your Repository.
3. Open up "Branches" then "Remote Tracking".

They should all be in there. Right click and "checkout."

The following assumes that your hours and minutes are stored as ints in variables named hh and mm respectively.

if ((hh > START_HOUR || (hh == START_HOUR && mm >= START_MINUTE)) &&
        (hh < END_HOUR || (hh == END_HOUR && mm <= END_MINUTE))) {
    ...
}

A CRLF is two characters, of course, the CR and the LF. However, `n consists of both. For example:

PS C:\> $x = "Hello
>> World"

PS C:\> $x
Hello
World
PS C:\> $x.contains("`n")
True
PS C:\> $x.contains("`r")
False
PS C:\> $x.replace("o`nW","o There`nThe W")
Hello There
The World
PS C:\>

I think you're running into problems with the `r. I was able to remove the `r from your example, use only `n, and it worked. Of course, I don't know exactly how you generated the original string so I don't know what's in there.

Something close to:

@Html.DropDownListFor(m => m.UserRole, 
   new SelectList(Model.Roles, "UserRoleId", "UserRole", Model.Roles.First().UserRoleId), 
   new { /* any html  attributes here */ }) 

You need a SelectList to populate the DropDownListFor. For any HTML attributes you need, you can add:

new { @class = "DropDown", @id = "dropdownUserRole" }

I want to point a different view on this general naming convention, e.g.:

see java.util.Set: boolean add?(E e)

where the rationale is:

do some processing then report whether it succeeded or not.

While the return is indeed a boolean the method's name should point the processing to complete instead of the result type (boolean for this example).

Your createFreshSnapshot example seems for me more related to this point of view because seems to mean this: create a fresh-snapshot then report whether the create-operation succeeded. Considering this reasoning the name createFreshSnapshot seems to be the best one for your situation.

This code will remove your whole cache of the application, You can check on app setting and open the app info and check the size of cache. Once you will use this code your cache size will be 0KB . So it and enjoy the clean cache.

 if (Build.VERSION_CODES.KITKAT <= Build.VERSION.SDK_INT) {
            ((ActivityManager) context.getSystemService(ACTIVITY_SERVICE))
                    .clearApplicationUserData();
            return;
        }

<input type="text" value="Your value">

Use the value attribute for the pre filled in values.

Please have a look at the below code sample;

Swift 4:

@IBDesignable class DesignableUITextField: UITextField {

    let border = CALayer()

    @IBInspectable var borderColor: UIColor? {
        didSet {
            setup()
        }
    }

    @IBInspectable var borderWidth: CGFloat = 0.5 {
        didSet {
            setup()
        }
    }

    func setup() {
        border.borderColor = self.borderColor?.cgColor

        border.borderWidth = borderWidth
        self.layer.addSublayer(border)
        self.layer.masksToBounds = true
    }

    override func layoutSubviews() {
        super.layoutSubviews()
        border.frame = CGRect(x: 0, y: self.frame.size.height - borderWidth, width:  self.frame.size.width, height: self.frame.size.height)
    }
 }

A note on the difference in speed. Attach the following snipet to an onclick call:

function myfunc()
{
    var timer = new Date();
    
        for(var i = 0; i < 10000; i++)
        {
            //document.getElementById('myID');
            $('#myID')[0];
        }
    

    console.log('timer: ' + (new Date() - timer));
}

Alternate commenting one out and then comment the other out. In my tests,

document.getElementbyId averaged about 35ms (fluctuating from 25ms up to 52ms on about 15 runs)

On the other hand, the

jQuery averaged about 200ms (ranging from 181ms to 222ms on about 15 runs).

From this simple test you can see that the jQuery took about 6 times as long.

Of course, that is over 10000 iterations so in a simpler situation I would probably use the jQuery for ease of use and all of the other cool things like .animate and .fadeTo. But yes, technically getElementById is quite a bit faster.

This is how it works in Swift 3:

@IBOutlet var myView: UIView!
override func viewDidLoad() {
    super.viewDidLoad()

    let tap = UITapGestureRecognizer(target: self, action:#selector(handleTap))

    myView.addGestureRecognizer(tap)
}

func handleTap() {
    print("tapped")
}

You can also just "not" add a url inside the <a> tag, i do this for menus that are <a> tag driven with drop downs as well. If there is not drop down then i add the url but if there are drop downs with a <ul> <li> list i just remove it.

Refer Below code which give the date in String form.

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



public class Test{

    public static void main(String[] args) {
        long val = 1346524199000l;
        Date date=new Date(val);
        SimpleDateFormat df2 = new SimpleDateFormat("dd/MM/yy");
        String dateText = df2.format(date);
        System.out.println(dateText);
    }
}

From book :

Choose a Random Row Using an Offset

Still another technique that avoids problems found in the preceding alternatives is to count the rows in the data set and return a random number between 0 and the count. Then use this number as an offset when querying the data set

$rand = "SELECT ROUND(RAND() * (SELECT COUNT(*) FROM Bugs))";
$offset = $pdo->query($rand)->fetch(PDO::FETCH_ASSOC);
$sql = "SELECT * FROM Bugs LIMIT 1 OFFSET :offset";
$stmt = $pdo->prepare($sql);
$stmt->execute( $offset );
$rand_bug = $stmt->fetch();

Use this solution when you can’t assume contiguous key values and you need to make sure each row has an even chance of being selected.

[Update]

More recently, there is Amazon AWS ECR (Elastic Container Registry), which provides a Docker image registry to which you can control access by means of the AWS IAM access management service. ECR can also run a CVE (vulnerabilities) check on your image when you push it.

Once you create your ECR, and obtain the "URL" you can push and pull as required, subject to the permissions you create: hence making it private or public as you wish.

Pricing is by amount of data stored, and data transfer costs.

[Original answer]

If you do not want to use the Docker Hub itself, you can host your own Docker repository under Artifactory by JFrog:

https://www.jfrog.com/confluence/display/RTF/Docker+Repositories

which will then run on your own server(s).

Other hosting suppliers are available, eg CoreOS:

which bought quay.io

Might not work you for, but a technique I've used a couple times in the past for similar circumstances.

created updated_{table_name}, then select insert into this table in batches. Once finished, and this hinges on Oracle ( which I don't know or use ) supporting the ability to rename tables in an atomic fashion. updated_{table_name} becomes {table_name} while {table_name} becomes original_{table_name}.

Last time I had to do this was for a heavily indexed table with several million rows that absolutely positively could not be locked for the duration needed to make some serious changes to it.

If you are having 112 columns in one single table and you would like to insert data from source table, you could do as

create table employees as select * from source_employees where employee_id=100;

Or from sqlplus do as

copy from source_schema/password insert employees using select * from 
source_employees where employee_id=100;

This generic method works too !

func didTapAttributedTextInLabel(gesture: UITapGestureRecognizer, inRange targetRange: NSRange) -> Bool {

        let layoutManager = NSLayoutManager()
        let textContainer = NSTextContainer(size: CGSize.zero)
        guard let strAttributedText = self.attributedText else {
            return false
        }

        let textStorage = NSTextStorage(attributedString: strAttributedText)

        // Configure layoutManager and textStorage
        layoutManager.addTextContainer(textContainer)
        textStorage.addLayoutManager(layoutManager)

        // Configure textContainer
        textContainer.lineFragmentPadding = Constants.lineFragmentPadding
        textContainer.lineBreakMode = self.lineBreakMode
        textContainer.maximumNumberOfLines = self.numberOfLines
        let labelSize = self.bounds.size
        textContainer.size = CGSize(width: labelSize.width, height: CGFloat.greatestFiniteMagnitude)

        // Find the tapped character location and compare it to the specified range
        let locationOfTouchInLabel = gesture.location(in: self)

        let xCordLocationOfTouchInTextContainer = locationOfTouchInLabel.x
        let yCordLocationOfTouchInTextContainer = locationOfTouchInLabel.y
        let locOfTouch = CGPoint(x: xCordLocationOfTouchInTextContainer ,
                                 y: yCordLocationOfTouchInTextContainer)

        let indexOfCharacter = layoutManager.characterIndex(for: locOfTouch, in: textContainer, fractionOfDistanceBetweenInsertionPoints: nil)

        guard let strLabel = text else {
            return false
        }

        let charCountOfLabel = strLabel.count

        if indexOfCharacter < (charCountOfLabel - 1) {
            return NSLocationInRange(indexOfCharacter, targetRange)
        } else {
            return false
        }
    }

And you can call the method with

let text = yourLabel.text
let termsRange = (text as NSString).range(of: fullString)
if yourLabel.didTapAttributedTextInLabel(gesture: UITapGestureRecognizer, inRange: termsRange) {
            showCorrespondingViewController()
        }

The most voted answer doesn't work. Here is mine and hope it helps.

function toUTF8($raw) {
    try{
        return mb_convert_encoding($raw, "UTF-8", "auto"); 
    }catch(\Exception $e){

}

Lot's of great answer. I just want to add a small note about decoupling the stream.

cin.tie(NULL);

I have faced an issue while decoupling the stream with CodeChef platform. When I submitted my code, the platform response was "Wrong Answer" but after tying the stream and testing the submission. It worked.

So, If anyone wants to untie the stream, the output stream must be flushed.

Edit: I am not familiar with all the platform but this is what I have experienced.

I don't believe you can do this with an accordion since it's specifically designed preserve the property that at most one item will be opened. However, even though you say you don't want to re-implement accordion, you might be over estimating the complexity involved.

Consider the following scenario where you have a vertical stack of elements,

++++++++++++++++++++
+     Header 1     +
++++++++++++++++++++
+                  +
+      Item 1      +
+                  +
++++++++++++++++++++
+     Header 2     +
++++++++++++++++++++
+                  +
+      Item 2      +
+                  +
++++++++++++++++++++

If you're lazy you could build this using a table, otherwise, suitably styled DIVs will also work.

Each of the item blocks can have a class of itemBlock. Clicking on a header will cause all elements of class itemBlock to be hidden ($(".itemBlock").hide()). You can then use the jquery slideDown() function to expand the item below the header. Now you've pretty much implemented accordion.

To expand all items, just use $(".itemBlock").show() or if you want it animated, $(".itemBlock").slideDown(500). To hide all items, just use $(".itemBlock").hide().

When the use logs in, put its username in the session:

`session.setAttribute("USER", username);`

At the beginning of each page you can do this:

<%
String username = (String)session.getAttribute("USER");
if(username==null) 
// if session is expired, forward it to login page
%>
<jsp:forward page="Login.jsp" />
<% { } %>

I've just get now the same issue with my video

<video preload="none" autoplay="autoplay" loop="loop">
  <source src="Home_Teaser.mp4" type="video/mp4">
  <source src="Home_Teaser" type="video/webm">
  <source src="Home_Teaser.ogv" type="video/ogg">
</video>

After search, I've found a solution:

If I set "preload" attributes to "true" the video start normally

As everyone has mentioned http.server module is equivalent to python -m SimpleHTTPServer.
But as a warning from https://docs.python.org/3/library/http.server.html#module-http.server

Warning: http.server is not recommended for production. It only implements basic security checks.

Usage

http.server can also be invoked directly using the -m switch of the interpreter.

python -m http.server

The above command will run a server by default on port number 8000. You can also give the port number explicitly while running the server

python -m http.server 9000

The above command will run an HTTP server on port 9000 instead of 8000.

By default, server binds itself to all interfaces. The option -b/--bind specifies a specific address to which it should bind. Both IPv4 and IPv6 addresses are supported. For example, the following command causes the server to bind to localhost only:

python -m http.server 8000 --bind 127.0.0.1

or

python -m http.server 8000 -b 127.0.0.1

Python 3.8 version also supports IPv6 in the bind argument.

Directory Binding

By default, server uses the current directory. The option -d/--directory specifies a directory to which it should serve the files. For example, the following command uses a specific directory:

python -m http.server --directory /tmp/

Directory binding is introduced in python 3.7

in Windows, you can use the runas command. For linux users, there are some alternatives for sudo in windows, you can check this out

http://helpdeskgeek.com/free-tools-review/5-windows-alternatives-linux-sudo-command/

just use rollback

Example code

try:
    cur.execute("CREATE TABLE IF NOT EXISTS test2 (id serial, qa text);")
except:
    cur.execute("rollback")
    cur.execute("CREATE TABLE IF NOT EXISTS test2 (id serial, qa text);")
