But, this code never stops (because of integer overflow) !?! Yves Daoust

For many numbers it will not overflow.

If it will overflow - for one of those unlucky initial seeds, the overflown number will very likely converge toward 1 without another overflow.

Still this poses interesting question, is there some overflow-cyclic seed number?

Any simple final converging series starts with power of two value (obvious enough?).

2^64 will overflow to zero, which is undefined infinite loop according to algorithm (ends only with 1), but the most optimal solution in answer will finish due to shr rax producing ZF=1.

Can we produce 2^64? If the starting number is 0x5555555555555555, it's odd number, next number is then 3n+1, which is 0xFFFFFFFFFFFFFFFF + 1 = 0. Theoretically in undefined state of algorithm, but the optimized answer of johnfound will recover by exiting on ZF=1. The cmp rax,1 of Peter Cordes will end in infinite loop (QED variant 1, "cheapo" through undefined 0 number).

How about some more complex number, which will create cycle without 0? Frankly, I'm not sure, my Math theory is too hazy to get any serious idea, how to deal with it in serious way. But intuitively I would say the series will converge to 1 for every number : 0 < number, as the 3n+1 formula will slowly turn every non-2 prime factor of original number (or intermediate) into some power of 2, sooner or later. So we don't need to worry about infinite loop for original series, only overflow can hamper us.

So I just put few numbers into sheet and took a look on 8 bit truncated numbers.

There are three values overflowing to 0: 227, 170 and 85 (85 going directly to 0, other two progressing toward 85).

But there's no value creating cyclic overflow seed.

Funnily enough I did a check, which is the first number to suffer from 8 bit truncation, and already 27 is affected! It does reach value 9232 in proper non-truncated series (first truncated value is 322 in 12th step), and the maximum value reached for any of the 2-255 input numbers in non-truncated way is 13120 (for the 255 itself), maximum number of steps to converge to 1 is about 128 (+-2, not sure if "1" is to count, etc...).

Interestingly enough (for me) the number 9232 is maximum for many other source numbers, what's so special about it? :-O 9232 = 0x2410 ... hmmm.. no idea.

Unfortunately I can't get any deep grasp of this series, why does it converge and what are the implications of truncating them to k bits, but with cmp number,1 terminating condition it's certainly possible to put the algorithm into infinite loop with particular input value ending as 0 after truncation.

But the value 27 overflowing for 8 bit case is sort of alerting, this looks like if you count the number of steps to reach value 1, you will get wrong result for majority of numbers from the total k-bit set of integers. For the 8 bit integers the 146 numbers out of 256 have affected series by truncation (some of them may still hit the correct number of steps by accident maybe, I'm too lazy to check).

Update:

Example from Microsoft:

Original

This is how I got client certification working and checking that a specific Root CA had issued it as well as it being a specific certificate.

First I edited <src>\.vs\config\applicationhost.config and made this change: <section name="access" overrideModeDefault="Allow" />

This allows me to edit <system.webServer> in web.config and add the following lines which will require a client certification in IIS Express. Note: I edited this for development purposes, do not allow overrides in production.

For production follow a guide like this to set up the IIS:

https://medium.com/@hafizmohammedg/configuring-client-certificates-on-iis-95aef4174ddb

web.config:

<security>
  <access sslFlags="Ssl,SslNegotiateCert,SslRequireCert" />
</security>

API Controller:

[RequireSpecificCert]
public class ValuesController : ApiController
{
    // GET api/values
    public IHttpActionResult Get()
    {
        return Ok("It works!");
    }
}

Attribute:

public class RequireSpecificCertAttribute : AuthorizationFilterAttribute
{
    public override void OnAuthorization(HttpActionContext actionContext)
    {
        if (actionContext.Request.RequestUri.Scheme != Uri.UriSchemeHttps)
        {
            actionContext.Response = new HttpResponseMessage(System.Net.HttpStatusCode.Forbidden)
            {
                ReasonPhrase = "HTTPS Required"
            };
        }
        else
        {
            X509Certificate2 cert = actionContext.Request.GetClientCertificate();
            if (cert == null)
            {
                actionContext.Response = new HttpResponseMessage(System.Net.HttpStatusCode.Forbidden)
                {
                    ReasonPhrase = "Client Certificate Required"
                };

            }
            else
            {
                X509Chain chain = new X509Chain();

                //Needed because the error "The revocation function was unable to check revocation for the certificate" happened to me otherwise
                chain.ChainPolicy = new X509ChainPolicy()
                {
                    RevocationMode = X509RevocationMode.NoCheck,
                };
                try
                {
                    var chainBuilt = chain.Build(cert);
                    Debug.WriteLine(string.Format("Chain building status: {0}", chainBuilt));

                    var validCert = CheckCertificate(chain, cert);

                    if (chainBuilt == false || validCert == false)
                    {
                        actionContext.Response = new HttpResponseMessage(System.Net.HttpStatusCode.Forbidden)
                        {
                            ReasonPhrase = "Client Certificate not valid"
                        };
                        foreach (X509ChainStatus chainStatus in chain.ChainStatus)
                        {
                            Debug.WriteLine(string.Format("Chain error: {0} {1}", chainStatus.Status, chainStatus.StatusInformation));
                        }
                    }
                }
                catch (Exception ex)
                {
                    Debug.WriteLine(ex.ToString());
                }
            }

            base.OnAuthorization(actionContext);
        }
    }

    private bool CheckCertificate(X509Chain chain, X509Certificate2 cert)
    {
        var rootThumbprint = WebConfigurationManager.AppSettings["rootThumbprint"].ToUpper().Replace(" ", string.Empty);

        var clientThumbprint = WebConfigurationManager.AppSettings["clientThumbprint"].ToUpper().Replace(" ", string.Empty);

        //Check that the certificate have been issued by a specific Root Certificate
        var validRoot = chain.ChainElements.Cast<X509ChainElement>().Any(x => x.Certificate.Thumbprint.Equals(rootThumbprint, StringComparison.InvariantCultureIgnoreCase));

        //Check that the certificate thumbprint matches our expected thumbprint
        var validCert = cert.Thumbprint.Equals(clientThumbprint, StringComparison.InvariantCultureIgnoreCase);

        return validRoot && validCert;
    }
}

Can then call the API with client certification like this, tested from another web project.

[RoutePrefix("api/certificatetest")]
public class CertificateTestController : ApiController
{

    public IHttpActionResult Get()
    {
        var handler = new WebRequestHandler();
        handler.ClientCertificateOptions = ClientCertificateOption.Manual;
        handler.ClientCertificates.Add(GetClientCert());
        handler.UseProxy = false;
        var client = new HttpClient(handler);
        var result = client.GetAsync("https://localhost:44331/api/values").GetAwaiter().GetResult();
        var resultString = result.Content.ReadAsStringAsync().GetAwaiter().GetResult();
        return Ok(resultString);
    }

    private static X509Certificate GetClientCert()
    {
        X509Store store = null;
        try
        {
            store = new X509Store(StoreName.My, StoreLocation.CurrentUser);
            store.Open(OpenFlags.OpenExistingOnly | OpenFlags.ReadOnly);

            var certificateSerialNumber= "?81 c6 62 0a 73 c7 b1 aa 41 06 a3 ce 62 83 ae 25".ToUpper().Replace(" ", string.Empty);

            //Does not work for some reason, could be culture related
            //var certs = store.Certificates.Find(X509FindType.FindBySerialNumber, certificateSerialNumber, true);

            //if (certs.Count == 1)
            //{
            //    var cert = certs[0];
            //    return cert;
            //}

            var cert = store.Certificates.Cast<X509Certificate>().FirstOrDefault(x => x.GetSerialNumberString().Equals(certificateSerialNumber, StringComparison.InvariantCultureIgnoreCase));

            return cert;
        }
        finally
        {
            store?.Close();
        }
    }
}

please see the above code.

The Problem is the "as string" in your function. Replace it with "as double" or "as long" to make it work. This way it even works if the last row is bigger than the "large number" proposed in the accepted answer.

So this should work

Function ultimaFilaBlanco(col As double) As Long        
    Dim lastRow As Long
    With ActiveSheet
        lastRow = ActiveSheet.Cells(ActiveSheet.Rows.Count, col).End(xlUp).row
    End With            
    ultimaFilaBlanco = lastRow          
End Function

You should be able to attach an event handler to the onchange event of the input and have that call a function to set the text in your span.

<script type="text/javascript">
  $(function() {
     $("input:file").change(function (){
       var fileName = $(this).val();
       $(".filename").html(fileName);
     });
  });
</script>

You may want to add IDs to your input and span so you can select based on those to be specific to the elements you are concerned with and not other file inputs or spans in the DOM.

Adding to the answers already given, here is a version that first checks whether the new branch already exists (so you can safely use it in a script)

if git ls-remote --heads "$remote" \
    | cut -f2 \
    | sed 's:refs/heads/::' \
    | grep -q ^"$newname"$; then
    echo "Error: $newname already exists"
    exit 1
fi
git push "$oldname" "$remote/$oldname:refs/heads/$newname" ":$oldname"

(the check is from this answer)

<div id="load" style="display:none"><img src="ajax-loader.gif"/></div>

function getData(p){
        var page=p;
        document.getElementById("load").style.display = "block";  // show the loading message.
        $.ajax({
            url: "loadData.php?id=<? echo $id; ?>",
            type: "POST",
            cache: false,
            data: "&page="+ page,
            success : function(html){
                $(".content").html(html);
        document.getElementById("load").style.display = "none";
            }
        });

addEventListener and removeEventListener,the Callback must not be Anonymous inner class,and they should have the same params

which(df==my.val, arr.ind=TRUE)

Fast, simple, but maybe not always right:

>>> [x for x in mylist if x.isdigit()]
['1', '2', '3', '4']

More traditional if you need to get numbers:

new_list = []
for value in mylist:
    try:
        new_list.append(int(value))
    except ValueError:
        continue

Note: The result has integers. Convert them back to strings if needed, replacing the lines above with:

try:
    new_list.append(str(int(value)))

Since version 5.6.3 Gradle documentation provides simple rules of thumb to identify whether an old compile dependency (or a new one) should be replaced with an implementation or an api dependency:

• Prefer the implementation configuration over api when possible

This keeps the dependencies off of the consumer’s compilation classpath. In addition, the consumers will immediately fail to compile if any implementation types accidentally leak into the public API.

So when should you use the api configuration? An API dependency is one that contains at least one type that is exposed in the library binary interface, often referred to as its ABI (Application Binary Interface). This includes, but is not limited to:

• types used in super classes or interfaces
• types used in public method parameters, including generic parameter types (where public is something that is visible to compilers. I.e. , public, protected and package private members in the Java world)
• types used in public fields
• public annotation types

By contrast, any type that is used in the following list is irrelevant to the ABI, and therefore should be declared as an implementation dependency:

• types exclusively used in method bodies
• types exclusively used in private members
• types exclusively found in internal classes (future versions of Gradle will let you declare which packages belong to the public API)

From what you have in Jason's comments try:

$('a').click(function() //this will apply to all anchor tags
{ 
   $('#area').val('foobar'); //this puts the textarea for the id labeled 'area'
})

Edit- To append to text look at below

$('a').click(function() //this will apply to all anchor tags
{ 
   $('#area').val($('#area').val()+'foobar'); 
})

Not sure if this is correct in any sense but this seems to work for me.

someHeader.h
inline int someVar;

I don't have linking/multiple definition issues and it "just works"... ;- )

It's quite handy for "quick" tests... Try to avoid global vars tho, because every says so... ;- )

Since C90, you can simply use:

dest_struct = source_struct;

as long as the string is memorized inside an array:

struct xxx {
    char theString[100];
};

Otherwise, if it's a pointer, you'll need to copy it by hand.

struct xxx {
    char* theString;
};

dest_struct = source_struct;
dest_struct.theString = malloc(strlen(source_struct.theString) + 1);
strcpy(dest_struct.theString, source_struct.theString);

try this

List<String> list = new ArrayList<String>();
list.add("List1");
list.add("List2");

String[] listArr = new String[list.size()];
listArr = list.toArray(listArr );

for(String s : listArr )
    System.out.println(s);

I would definitely suggest using element.getBoundingClientRect().

https://developer.mozilla.org/en-US/docs/Web/API/element.getBoundingClientRect

Summary

Returns a text rectangle object that encloses a group of text rectangles.

Syntax

var rectObject = object.getBoundingClientRect();

Returns

The returned value is a TextRectangle object which is the union of the rectangles returned by getClientRects() for the element, i.e., the CSS border-boxes associated with the element.

The returned value is a TextRectangle object, which contains read-only left, top, right and bottom properties describing the border-box, in pixels, with the top-left relative to the top-left of the viewport.

Here's a browser compatibility table taken from the linked MDN site:

+---------------+--------+-----------------+-------------------+-------+--------+
|    Feature    | Chrome | Firefox (Gecko) | Internet Explorer | Opera | Safari |
+---------------+--------+-----------------+-------------------+-------+--------+
| Basic support | 1.0    | 3.0 (1.9)       | 4.0               | (Yes) | 4.0    |
+---------------+--------+-----------------+-------------------+-------+--------+

It's widely supported, and is really easy to use, not to mention that it's really fast. Here's a related article from John Resig: http://ejohn.org/blog/getboundingclientrect-is-awesome/

You can use it like this:

var logo = document.getElementById('hlogo');
var logoTextRectangle = logo.getBoundingClientRect();

console.log("logo's left pos.:", logoTextRectangle.left);
console.log("logo's right pos.:", logoTextRectangle.right);

Here's a really simple example: http://jsbin.com/awisom/2 (you can view and edit the code by clicking "Edit in JS Bin" in the upper right corner).

Or here's another one using Chrome's console:

Note:

I have to mention that the width and height attributes of the getBoundingClientRect() method's return value are undefined in Internet Explorer 8. It works in Chrome 26.x, Firefox 20.x and Opera 12.x though. Workaround in IE8: for width, you could subtract the return value's right and left attributes, and for height, you could subtract bottom and top attributes (like this).

If you have more than one view in the layout file android.R.layout.simple_list_item_1 then you'll have to pass the third argument android.R.id.text1 to specify the view that should be filled with the array elements (values). But if you have just one view in your layout file, there is no need to specify the third argument.

Options A, B and D seem to be in the same category since they only influence the initial start time, they do warmup of the website like compilation and loading of libraries in memory.

Using C, setting the idle timeout, should be enough so that subsequent requests to the server are served fast (restarting the app pool takes quite some time - in the order of seconds).

As far as I know, the timeout exists to save memory that other websites running in parallel on that machine might need. The price being that one time slow load time.

Besides the fact that the app pool gets shutdown in case of user inactivity, the app pool will also recycle by default every 1740 minutes (29 hours).

From technet:

Internet Information Services (IIS) application pools can be periodically recycled to avoid unstable states that can lead to application crashes, hangs, or memory leaks.

As long as app pool recycling is left on, it should be enough. But if you really want top notch performance for most components, you should also use something like the Application Initialization Module you mentioned.

BufferedImage is a subclass of Image. You don't need to do any conversion.

<shape xmlns:android="http://schemas.android.com/apk/res/android"
  android:padding="10dp"
  android:shape="rectangle">
    <solid android:color="@color/colorAccent" /> 
    <corners
      android:bottomLeftRadius="500dp"
      android:bottomRightRadius="500dp"
      android:topLeftRadius="500dp"
      android:topRightRadius="500dp" />
</shape>

Now, in which element you want to use this shape just add: android:background="@drawable/custom_round_ui_shape"

Create a new XML in drawable named "custom_round_ui_shape"

When the iFrame points to your site like this:

<html>
  <head>
    <script type="text/javascript" src="/jquery.js"></script>
  </head>
  <body>
    <iframe id="my_frame" src="/wherev"></iframe>
  </body>
</html>

You can access iFrame DOM through this kind of thing.

var iframeBody = $(window.my_frame.document.getElementsByTagName("body")[0]);
iframeBody.append($("<h1/>").html("Hello world!"));

The $ solution didn't work for me. However, By actually putting the tab character itself in the command did: sort -t'' -k2

This old question has a new answer. There are a few "async" solutions for PHP this days (which are equivalent to Python's multiprocess in the sense that they spawn new independent PHP processes rather than manage it at the framework level)

The two solutions I have seen are

• Quick and easy: https://github.com/spatie/async
• Big tank with concurrency management: https://github.com/amphp/amp

Give them a try!

<tr height="70" onclick="location.href='<%=site_adres2 & urun_adres%>'"
    style="cursor:pointer;">

>>> x = "2342.34"
>>> float(x)
2342.3400000000001

There you go. Use float (which behaves like and has the same precision as a C,C++, or Java double).

That code is invalid as you can only pass variables into language constructs. empty() is a language construct.

You have to do this in two lines:

$result = array_intersect($people, $criminals);
$result = !empty($result);

Most generic and simple way:

findObject(listOfObjects, objectToSearch) {
    let found = false, matchingKeys = 0;
    for(let object of listOfObjects) {
        found = false;
        matchingKeys = 0;
        for(let key of Object.keys(object)) {
            if(object[key]==objectToSearch[key]) matchingKeys++;
        }
        if(matchingKeys==Object.keys(object).length) {
            found = true;
            break;
        }
    }
    return found;
}

get_removed_list_of_objects(old_array, new_array) {
    // console.log('old:',old_array);
    // console.log('new:',new_array);
    let foundList = [];
    for(let object of old_array) {
        if(!this.findObject(new_array, object)) foundList.push(object);
    }
    return foundList;
}

get_added_list_of_objects(old_array, new_array) {
    let foundList = [];
    for(let object of new_array) {
        if(!this.findObject(old_array, object)) foundList.push(object);
    }
    return foundList;
}

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...

nginx "fails fast" when the client informs it that it's going to send a body larger than the client_max_body_size by sending a 413 response and closing the connection.

Most clients don't read responses until the entire request body is sent. Because nginx closes the connection, the client sends data to the closed socket, causing a TCP RST.

If your HTTP client supports it, the best way to handle this is to send an Expect: 100-Continue header. Nginx supports this correctly as of 1.2.7, and will reply with a 413 Request Entity Too Large response rather than 100 Continue if Content-Length exceeds the maximum body size.

All answers on this page are really great for a complex object. But for those containing builtin iterable types as attributes, like str, list, set or dict, or any implementation of collections.Iterable, you can omit certain things in your class.

class Test(object):
    def __init__(self, string):
        self.string = string

    def __iter__(self):
        # since your string is already iterable
        return (ch for ch in self.string)
        # or simply
        return self.string.__iter__()
        # also
        return iter(self.string)

It can be used like:

for x in Test("abcde"):
    print(x)

# prints
# a
# b
# c
# d
# e

I was able to bypass this error by invoking PowerShell like this:

powershell -executionpolicy bypass -File .\MYSCRIPT.ps1

That is, I added the -executionpolicy bypass to the way I invoked the script.

This worked on Windows 7 Service Pack 1. I am new to PowerShell, so there could be caveats to doing that that I am not aware of.

[Edit 2017-06-26] I have continued to use this technique on other systems including Windows 10 and Windows 2012 R2 without issue.

Here is what I am using now. This keeps me from accidentally running the script by clicking on it. When I run it in the scheduler I add one argument: "scheduler" and that bypasses the prompt.

This also pauses the window at the end so I can see the output of PowerShell.

if NOT "%1" == "scheduler" (
   @echo looks like you started the script by clicking on it.
   @echo press space to continue or control C to exit.
   pause
)

C:
cd \Scripts

powershell -executionpolicy bypass -File .\rundps.ps1

set psexitcode=%errorlevel%

if NOT "%1" == "scheduler" (
   @echo Powershell finished.  Press space to exit.
   pause
)

exit /b %psexitcode%

If I understand your question right:

To add a .net 2.0 Web Service Reference instead of a WCF Service Reference, right-click on your project and click 'Add Service Reference.'

Then click "Advanced.." at the bottom left of the dialog.

Then click "Add Web Reference.." on the bottom left of the next dialog.

Now you can add a regular SOAP web reference like you are looking for.

Works with over 100 lines, if you specify the size of the file in the headers simple call the get() method in your own class

You can add a wrapper around promise functionality to return an Observable to observer.

• Creating a Lazy Observable using defer() operator which allows you to create the Observable only when the Observer subscribes.

import { of, Observable, defer } from 'rxjs'; 
import { map } from 'rxjs/operators';


function getTodos$(): Observable<any> {
  return defer(()=>{
    return fetch('https://jsonplaceholder.typicode.com/todos/1')
      .then(response => response.json())
      .then(json => {
        return json;
      })
  });
}

getTodos$().
 subscribe(
   (next)=>{
     console.log('Data is:', next);
   }
)

It's the remainder operator and is used to get the remainder after integer division. Lots of languages have it. For example:

10 % 3 // = 1 ; because 3 * 3 gets you 9, and 10 - 9 is 1.

Apparently it is not the same as the modulo operator entirely.

Try Case

SELECT   stock.name,
      CASE 
         WHEN stock.quantity <20 THEN 'Buy urgent'
         ELSE 'There is enough'
      END
FROM stock

There is a difference between the navigation bar and the status bar. The confusing part is that it looks like one solid feature at the top of the screen, but the areas can actually be separated into two distinct views; a status bar and a navigation bar. The status bar spans from y=0 to y=20 points and the navigation bar spans from y=20 to y=64 points. So the navigation bar (which is where the page title and navigation buttons go) has a height of 44 points, but the status bar and navigation bar together have a total height of 64 points.

Don't pass the result of swapImages to setInterval by invoking it. Just pass the function, like this:

Is it possible to select an element if it contains a specific child element?

Unfortunately not yet.

The CSS2 and CSS3 selector specifications do not allow for any sort of parent selection.

A Note About Specification Changes

This is a disclaimer about the accuracy of this post from this point onward. Parent selectors in CSS have been discussed for many years. As no consensus has been found, changes keep happening. I will attempt to keep this answer up-to-date, however be aware that there may be inaccuracies due to changes in the specifications.

An older "Selectors Level 4 Working Draft" described a feature which was the ability to specify the "subject" of a selector. This feature has been dropped and will not be available for CSS implementations.

The subject was going to be the element in the selector chain that would have styles applied to it.

<p><span>lorem</span> ipsum dolor sit amet</p>
<p>consecteture edipsing elit</p>

This selector would style the span element

p span {
    color: red;
}

This selector would style the p element

!p span {
    color: red;
}

A more recent "Selectors Level 4 Editor’s Draft" includes "The Relational Pseudo-class: :has()"

:has() would allow an author to select an element based on its contents. My understanding is it was chosen to provide compatibility with jQuery's custom :has() pseudo-selector*.

In any event, continuing the example from above, to select the p element that contains a span one could use:

p:has(span) {
    color: red;
}

_{* This makes me wonder if jQuery had implemented selector subjects whether subjects would have remained in the specification.}

CA's don't ask for your private keys! They only asks for CSR to issue a certificate for you.

If they have your private key, it's possible that your SSL certificate will be compromised and end up being revoked.

Your .key file is generated during CSR generation and, most probably, it's somewhere on your PC where you generated the CSR.

That's why private key is called "Private" - because nobody can have that file except you.

No, Bootstrap does not introduce special considerations for disabling a drop-down.

<select id="xxx" name="xxx" class="input-medium" disabled>

or

<select id="xxx" name="xxx" class="input-medium" disabled="disabled">

will work. I prefer to give attributes values (as in the second form; in XHTML, attributes must have a value), but the HTML spec says:

The presence of a boolean attribute on an element represents the true value, and the absence of the attribute represents the false value.

(from http://www.whatwg.org/specs/web-apps/current-work/multipage/common-microsyntaxes.html#boolean-attribute)

The key differences between read-only and disabled:*

The Disabled attribute

• Values for disabled form elements are not passed to the processor method. The W3C calls this a successful element.(This works similar to form check boxes that are not checked.)
• Some browsers may override or provide default styling for disabled form elements. (Gray out or emboss text) Internet Explorer 5.5 is particularly nasty about this.
• Disabled form elements do not receive focus.
• Disabled form elements are skipped in tabbing navigation.

The Read Only Attribute

• Not all form elements have a readonly attribute. Most notable, the <SELECT>, <OPTION>, and <BUTTON> elements do not have readonly attributes (although thy both have disabled attributes)
• Browsers provide no default overridden visual feedback that the form element is read only
• Form elements with the readonly attribute set will get passed to the form processor.
• Read only form elements can receive the focus
• Read only form elements are included in tabbed navigation.

You can't use Template expression operators(pipe, save navigator) within template statement:

(ngModelChange)="Template statements"

(ngModelChange)="item.value | useMyPipeToFormatThatValue=$event"

https://angular.io/guide/template-syntax#template-statements

Like template expressions, template statements use a language that looks like JavaScript. The template statement parser differs from the template expression parser and specifically supports both basic assignment (=) and chaining expressions (with ; or ,).

However, certain JavaScript syntax is not allowed:

• new
• increment and decrement operators, ++ and --
• operator assignment, such as += and -=
• the bitwise operators | and &
• the template expression operators

So you should write it as follows:

<input [ngModel]="item.value | useMyPipeToFormatThatValue" 
      (ngModelChange)="item.value=$event" name="inputField" type="text" />

Plunker Example

We had the same problem. We have a big VS 2015 solution with multiple C# projects in it and even more test projects.

Resharper's test discovery worked just fine, but VS Test Explorer failed miserably.

Turns out that the projects didn't have the same version of MsTest TestFramework and TestAdapter, and that sometimes they used NuGets and other times good old references, and that is not supported apparently (so much for such an expensive IDE).

Removing all Microsoft.VisualStudio.Test* references and then adding / updating the two MSTest NuGets fixed the problem.

This works for me (no Azure), SQL 2008 R2 on dev server or localdb\mssqllocaldb on local workstation. Note: entity adds Create, CreateBy, Modified, ModifiedBy and Version columns.

public class Carrier : Entity
{
    public Guid Id { get; set; }
    public string Code { get; set; }
    public string Name { get; set; }
}

then create a mapping configuration class

public class CarrierMap : EntityTypeConfiguration<Carrier>
{
    public CarrierMap()
    {
        HasKey(p => p.Id);

        Property(p => p.Id).HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity);

        Property(p => p.Code)
            .HasMaxLength(4)
            .IsRequired()
            .HasColumnAnnotation("Index", new IndexAnnotation(new IndexAttribute { IsClustered = true, IsUnique = true }));

        Property(p => p.Name).HasMaxLength(255).IsRequired();
        Property(p => p.Created).HasPrecision(7).IsRequired();
        Property(p => p.Modified)
            .HasColumnAnnotation("IX_Modified", new IndexAnnotation(new IndexAttribute()))
            .HasPrecision(7)
            .IsRequired();
        Property(p => p.CreatedBy).HasMaxLength(50).IsRequired();
        Property(p => p.ModifiedBy).HasMaxLength(50).IsRequired();
        Property(p => p.Version).IsRowVersion();
    }
}

This creates an Up method in the initial DbMigration when you execute add-migration like this

        CreateTable(
            "scoFreightRate.Carrier",
            c => new
                {
                    Id = c.Guid(nullable: false, identity: true),
                    Code = c.String(nullable: false, maxLength: 4),
                    Name = c.String(nullable: false, maxLength: 255),
                    Created = c.DateTimeOffset(nullable: false, precision: 7),
                    CreatedBy = c.String(nullable: false, maxLength: 50),
                    Modified = c.DateTimeOffset(nullable: false, precision: 7,
                        annotations: new Dictionary<string, AnnotationValues>
                        {
                            { 
                                "IX_Modified",
                                new AnnotationValues(oldValue: null, newValue: "IndexAnnotation: { }")
                            },
                        }),
                    ModifiedBy = c.String(nullable: false, maxLength: 50),
                    Version = c.Binary(nullable: false, fixedLength: true, timestamp: true, storeType: "rowversion"),
                })
            .PrimaryKey(t => t.Id)
            .Index(t => t.Code, unique: true, clustered: true);

Note: that the Id columns does not get a default value, don't worry

Now execute Update-Database, and you should end up with a table definition in your database like this:

CREATE TABLE [scoFreightRate].[Carrier] (
    [Id]         UNIQUEIDENTIFIER   DEFAULT (newsequentialid()) NOT NULL,
    [Code]       NVARCHAR (4)       NOT NULL,
    [Name]       NVARCHAR (255)     NOT NULL,
    [Created]    DATETIMEOFFSET (7) NOT NULL,
    [CreatedBy]  NVARCHAR (50)      NOT NULL,
    [Modified]   DATETIMEOFFSET (7) NOT NULL,
    [ModifiedBy] NVARCHAR (50)      NOT NULL,
    [Version]    ROWVERSION         NOT NULL,
    CONSTRAINT [PK_scoFreightRate.Carrier] PRIMARY KEY NONCLUSTERED ([Id] ASC)
);


GO
CREATE UNIQUE CLUSTERED INDEX [IX_Code]
    ON [scoFreightRate].[Carrier]([Code] ASC);

Note: we have a overridden the SqlServerMigrationSqlGenerator to ensure it does NOT make the Primary Key a Clustered index as we encourage our developers to set a better clustered index on tables

public class OurMigrationSqlGenerator : SqlServerMigrationSqlGenerator
{
    protected override void Generate(AddPrimaryKeyOperation addPrimaryKeyOperation)
    {
        if (addPrimaryKeyOperation == null) throw new ArgumentNullException("addPrimaryKeyOperation");
        if (!addPrimaryKeyOperation.Table.Contains("__MigrationHistory"))
            addPrimaryKeyOperation.IsClustered = false;
        base.Generate(addPrimaryKeyOperation);
    }

    protected override void Generate(CreateTableOperation createTableOperation)
    {
        if (createTableOperation == null) throw new ArgumentNullException("createTableOperation");
        if (!createTableOperation.Name.Contains("__MigrationHistory"))
            createTableOperation.PrimaryKey.IsClustered = false;
        base.Generate(createTableOperation);
    }

    protected override void Generate(MoveTableOperation moveTableOperation)
    {
        if (moveTableOperation == null) throw new ArgumentNullException("moveTableOperation");
        if (!moveTableOperation.CreateTableOperation.Name.Contains("__MigrationHistory")) moveTableOperation.CreateTableOperation.PrimaryKey.IsClustered = false;
        base.Generate(moveTableOperation);
    }
}

The official MS line is "because it's not a functional operation" (ie it's a stateful operation).

Couldn't you do something like:

list.Select( x => x+1 )

or if you really need it in a List:

var someValues = new List<int>( list.Select( x => x+1 ) );

If you need to have production application.yml completely replaced then put its test version to the same path but in test environment (usually it is src/test/resources/)

But if you need to override or add some properties then you have few options.

Option 1: put test application.yml in src/test/resources/config/ directory as @TheKojuEffect suggests in his answer.

Option 2: use profile-specific properties: create say application-test.yml in your src/test/resources/ folder and:

• add @ActiveProfiles annotation to your test classes:

  @SpringBootTest(classes = Application.class)
  @ActiveProfiles("test")
  public class MyIntTest {
  

• or alternatively set spring.profiles.active property value in @SpringBootTest annotation:

  @SpringBootTest(
          properties = ["spring.profiles.active=test"],
          classes = Application.class,
  )
  public class MyIntTest {
  

This works not only with @SpringBootTest but with @JsonTest, @JdbcTests, @DataJpaTest and other slice test annotations as well.

And you can set as many profiles as you want (spring.profiles.active=dev,hsqldb) - see farther details in documentation on Profiles.

The answer is due to the fact that Google Chrome uses an SQLite file to save cookies. It resides under:

C:\Users\<your_username>\AppData\Local\Google\Chrome\User Data\Default\

inside Cookies file. (which is an SQLite database file)

So it's not a file stored on hard drive but a row in an SQLite database file which can be read by a third party program such as: SQLite Database Browser

EDIT: Thanks to @Chexpir, it is also good to know that the values are stored encrypted.

Cloning the objects before adding them. For example, instead of newList.addAll(oldList);

for(Person p : oldList) {
    newList.add(p.clone());
}

Assuming clone is correctly overriden inPerson.

No you might need to trigger it manually after setting the value:

$('#mytext').change();

or:

$('#mytext').trigger('change');

This issue happening while implementing Mockito with spring boot api. Below add below dependency in in gradle file

compile group: 'org.mockito', name: 'mockito-core', version: '2.22.0'

Note: Spring boot version 2.2.0

This question has already been answered accurately by Richard210363.

However, I would like to point out that there is another way to do this, and to warn that this alternate approach should be avoided, as it causes problems.

As R0MANARMY stated in a comment to the original question, it is possible to create a repo from the existing solution folder using the git command line or even Git Gui. However, when you do this it adds all the files below that folder to the repo, including build output (bin/ obj/ folders) user options files (.suo, .csproj.user) and numerous other files that may be in your solution folder but that you don't want to include in your repo. One unwanted side effect of this is that after building locally, the build output will show up in your "changes" list.

When you add using "Select File | Add to Source Control" in Visual Studio, it intelligently includes the correct project and solution files, and leaves the other ones out. Also it automatically creates a .gitignore file that helps prevent these unwanted files from being added to the repo in the future.

If you have already created a repo that includes these unwanted files and then add the .gitignore file at a later time, the unwanted files will still remain part of the repo and will need to be removed manually... it's probably easier to delete the repo and start over again by creating the repo the correct way.

I've already answered this question, but I'll do it again since in the meanwhile I've learnt that there are special cases if you're running in CLI (redirects cannot happen and thus shouldn't exit()) or if your webserver is running PHP as a (F)CGI (it needs a previously set Status header to properly redirect).

function Redirect($url, $code = 302)
{
    if (strncmp('cli', PHP_SAPI, 3) !== 0)
    {
        if (headers_sent() !== true)
        {
            if (strlen(session_id()) > 0) // If using sessions
            {
                session_regenerate_id(true); // Avoids session fixation attacks
                session_write_close(); // Avoids having sessions lock other requests
            }

            if (strncmp('cgi', PHP_SAPI, 3) === 0)
            {
                header(sprintf('Status: %03u', $code), true, $code);
            }

            header('Location: ' . $url, true, (preg_match('~^30[1237]$~', $code) > 0) ? $code : 302);
        }

        exit();
    }
}

I've also handled the issue of supporting the different HTTP redirection codes (301, 302, 303 and 307), as it was addressed in the comments of my previous answer. Here are the descriptions:

• 301 - Moved Permanently
• 302 - Found
• 303 - See Other
• 307 - Temporary Redirect (HTTP/1.1)

The quickest fix for me was doing the following:

cd /usr/local
git reset --hard FETCH_HEAD

Then I retried brew install imagemagick and it correctly pulled the package from the new mirror, instead of adamv.

If that does not work, ensure that /Library/Caches/Homebrew does not contain any imagemagick files or folders. Delete them if it does.

Yes, as long as no one is looking over your shoulder at the monitor.

in fact the Is is really good, since to the developpers, you may want to override the operator ==, to compare with the value. say you have a class A, operator == of A is to compare some of the field of A to the parameter. then you will be in trouble in c# to verify whether the object of A is null with following code,

    A a = new A();
...
    if (a != null)
it will totally wrong, you always need to use if((object)a != null)
but in vb.net you cannot write in this way, you always need to write
    if not a is nothing then
or
    if a isnot nothing then

which just as Christian said, vb.net does not 'expected' anything.

If you try appending the number like, say listName.append(4) , this will append 4 at last. But if you are trying to take <int> and then append it as, num = 4 followed by listName.append(num), this will give you an error as 'num' is of <int> type and listName is of type <list>. So do type cast int(num) before appending it.

Yes, according to RFC 3696 apostrophes are valid as long as they come before the @ symbol.

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

 void MyMethod(Func<int> param1 = null) 

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

So if you AS usage was

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

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

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

Easy way to parse the xml is to use the LINQ to XML

for example you have the following xml file

<library>
    <track id="1" genre="Rap" time="3:24">
        <name>Who We Be RMX (feat. 2Pac)</name>
        <artist>DMX</artist>
        <album>The Dogz Mixtape: Who's Next?!</album>
    </track>
    <track id="2" genre="Rap" time="5:06">
        <name>Angel (ft. Regina Bell)</name>
        <artist>DMX</artist>
        <album>...And Then There Was X</album>
    </track>
    <track id="3" genre="Break Beat" time="6:16">
        <name>Dreaming Your Dreams</name>
        <artist>Hybrid</artist>
        <album>Wide Angle</album>
    </track>
    <track id="4" genre="Break Beat" time="9:38">
        <name>Finished Symphony</name>
        <artist>Hybrid</artist>
        <album>Wide Angle</album>
    </track>
<library>

For reading this file, you can use the following code:

public void Read(string  fileName)
{
    XDocument doc = XDocument.Load(fileName);

    foreach (XElement el in doc.Root.Elements())
    {
        Console.WriteLine("{0} {1}", el.Name, el.Attribute("id").Value);
        Console.WriteLine("  Attributes:");
        foreach (XAttribute attr in el.Attributes())
            Console.WriteLine("    {0}", attr);
        Console.WriteLine("  Elements:");

        foreach (XElement element in el.Elements())
            Console.WriteLine("    {0}: {1}", element.Name, element.Value);
    }
}

You should use parameters in your query to prevent attacks, like if someone entered '); drop table ArticlesTBL;--' as one of the values.

string query = "INSERT INTO ArticlesTBL (ArticleTitle, ArticleContent, ArticleType, ArticleImg, ArticleBrief,  ArticleDateTime, ArticleAuthor, ArticlePublished, ArticleHomeDisplay, ArticleViews)";
query += " VALUES (@ArticleTitle, @ArticleContent, @ArticleType, @ArticleImg, @ArticleBrief, @ArticleDateTime, @ArticleAuthor, @ArticlePublished, @ArticleHomeDisplay, @ArticleViews)";

SqlCommand myCommand = new SqlCommand(query, myConnection);
myCommand.Parameters.AddWithValue("@ArticleTitle", ArticleTitleTextBox.Text);
myCommand.Parameters.AddWithValue("@ArticleContent", ArticleContentTextBox.Text);
// ... other parameters
myCommand.ExecuteNonQuery();

(xkcd)

The getActiveNetworkInfo() method of ConnectivityManager returns a NetworkInfo instance representing the first connected network interface it can find or null if none of the interfaces are connected. Checking if this method returns null should be enough to tell if an internet connection is available or not.

private boolean isNetworkAvailable() {
    ConnectivityManager connectivityManager 
          = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
    return activeNetworkInfo != null && activeNetworkInfo.isConnected();
}

You will also need:

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

in your android manifest.

Edit:

Note that having an active network interface doesn't guarantee that a particular networked service is available. Network issues, server downtime, low signal, captive portals, content filters and the like can all prevent your app from reaching a server. For instance you can't tell for sure if your app can reach Twitter until you receive a valid response from the Twitter service.

I know that this question is pretty old, but I stumbled upon it recently, found a solution that I liked better, and figured I'd share it.

Now that Bootstrap 5 is available, there's a new approach that works similarly to using input-groups, but looks more like an ordinary form, without any CSS tweaks:

<div class="row g-3 align-items-center">
    <div class="col-auto">
        <label>Label:</label>
    </div>
    <div class="col">
        <input class="form-control">
    </div>
    <div class="col-auto">
        <button type="button" class="btn btn-primary">Button</button>
    </div>
</div>

The col-auto class makes those columns fit themselves to their contents (the label and the button in this case), and anything with a col class should be evenly distributed to take up the remaining space.

the algorithm : ((x1 - x2) ^ 2 + (y1 - y2) ^ 2) < 25

The main difference between logging in with a postgres user or any other user created by us, is that when using the postgres user it is NOT necessary to specify the host with -h and instead for another user if.

Login with postgres user

$ psql -U postgres 

Creation and login with another user

# CREATE ROLE usertest LOGIN PASSWORD 'pwtest';
# CREATE DATABASE dbtest WITH OWNER = usertest;
# SHOW port;
# \q

$ psql -h localhost -d dbtest -U usertest -p 5432

Okay, so if you don't have LINQ, you could hard-code it:

public int FindMaxAge(List<MyType> list)
{
    if (list.Count == 0)
    {
        throw new InvalidOperationException("Empty list");
    }
    int maxAge = int.MinValue;
    foreach (MyType type in list)
    {
        if (type.Age > maxAge)
        {
            maxAge = type.Age;
        }
    }
    return maxAge;
}

Or you could write a more general version, reusable across lots of list types:

public int FindMaxValue<T>(List<T> list, Converter<T, int> projection)
{
    if (list.Count == 0)
    {
        throw new InvalidOperationException("Empty list");
    }
    int maxValue = int.MinValue;
    foreach (T item in list)
    {
        int value = projection(item);
        if (value > maxValue)
        {
            maxValue = value;
        }
    }
    return maxValue;
}

You can use this with:

// C# 2
int maxAge = FindMaxValue(list, delegate(MyType x) { return x.Age; });

// C# 3
int maxAge = FindMaxValue(list, x => x.Age);

Or you could use LINQBridge :)

In each case, you can return the if block with a simple call to Math.Max if you want. For example:

foreach (T item in list)
{
    maxValue = Math.Max(maxValue, projection(item));
}

seeing it in digital circuit domain

1. A Wire will create a wire output which can only be assigned any input by using assign statement as assign statement creates a port/pin connection and wire can be joined to the port/pin
2. A reg will create a register(D FLIP FLOP ) which gets or recieve inputs on basis of sensitivity list either it can be clock (rising or falling ) or combinational edge .

so it completely depends on your use whether you need to create a register and tick it according to sensitivity list or you want to create a port/pin assignment

You should be able to compare them directly.

var date = moment("2013-03-24")
var now = moment();

if (now > date) {
   // date is past
} else {
   // date is future
}

    var now = moment();_x000D_
    var then = moment(date);_x000D_

I'm using Laravel Lumen to build a small application.
For me it was because I didn't had the DB_USERNAME defined in my .env file.

DB_USERNAME=root

Setting this solved my problem.

If you're looking a way to convert autogenerated comment from Add Documentation action (available under cmd-shift-/) you might find it useful too:

function run(input, parameters) {
  var lines = input[0].split('\n');
  var line1 = lines[0];
  var prefixRe = /^( *)\/\/\/?(.*)/gm;
  var prefix = prefixRe.test(line1) ? line1.replace(prefixRe, "$1") : ""

  var result = prefix + "/*\n";  
  lines.forEach(function(line) {
    result += prefix + line.replace(prefixRe, "$2") + '\n';
  });
  result += '\n' + prefix + ' */';
  return result;
}

Rest the same as in @Charles Robertson answer:

Updated @Hussein solution with preview height that will adapt to the paragraph number of lines.

So with this bit of code : - You can choose the number of lines you want to show in preview, it will works for all screen sizes, even if font-size is responsive. - There is no need to add classes or back-end editing to separate preview from whole content.

http://jsfiddle.net/7Vv8u/5816/

var h = $('div')[0].scrollHeight;

divLineHeight = parseInt($('div').css('line-height'));
divPaddingTop = parseInt($('div').css('padding-top'));
lineToShow = 2;
divPreviewHeight = divLineHeight*lineToShow - divPaddingTop;
$('div').css('height', divPreviewHeight );

$('#more').click(function(e) {
  e.stopPropagation();
  $('div').animate({
    'height': h
  })
});

$(document).click(function() {
  $('div').animate({
    'height': divPreviewHeight
  })
})

You can iterate through the array or you can convert it to a String and use indexOf.

if (new String(charArray).indexOf('q') < 0) {
    break;
}

Creating a new String is a bit wasteful, but it's probably the tersest code. You can also write a method to imitate the effect without incurring the overhead.

Arrays

• Set, Check element at a particular index: O(1)
• Searching: O(n) if array is unsorted and O(log n) if array is sorted and something like a binary search is used,
• As pointed out by Aivean, there is no Delete operation available on Arrays. We can symbolically delete an element by setting it to some specific value, e.g. -1, 0, etc. depending on our requirements
• Similarly, Insert for arrays is basically Set as mentioned in the beginning

ArrayList:

• Add: Amortized O(1)
• Remove: O(n)
• Contains: O(n)
• Size: O(1)

Linked List:

• Inserting: O(1), if done at the head, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Deleting: O(1), if done at the head, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Searching: O(n)

Doubly-Linked List:

• Inserting: O(1), if done at the head or tail, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Deleting: O(1), if done at the head or tail, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Searching: O(n)

Stack:

• Push: O(1)
• Pop: O(1)
• Top: O(1)
• Search (Something like lookup, as a special operation): O(n) (I guess so)

Queue/Deque/Circular Queue:

• Insert: O(1)
• Remove: O(1)
• Size: O(1)

Binary Search Tree:

• Insert, delete and search: Average case: O(log n), Worst Case: O(n)

Red-Black Tree:

• Insert, delete and search: Average case: O(log n), Worst Case: O(log n)

Heap/PriorityQueue (min/max):

• Find Min/Find Max: O(1)
• Insert: O(log n)
• Delete Min/Delete Max: O(log n)
• Extract Min/Extract Max: O(log n)
• Lookup, Delete (if at all provided): O(n), we will have to scan all the elements as they are not ordered like BST

HashMap/Hashtable/HashSet:

• Insert/Delete: O(1) amortized
• Re-size/hash: O(n)
• Contains: O(1)

If you want to overwrite only one file:

git fetch
git checkout origin/master <filepath>

If you want to overwrite all changed files:

git fetch
git reset --hard origin/master

(This assumes that you're working on master locally and you want the changes on the origin's master - if you're on a branch, substitute that in instead.)

Try

SELECT li.clientid, group_concat(li.views ORDER BY li.views) AS views,
       group_concat(li.percentage ORDER BY li.percentage) 
FROM table_views li 
GROUP BY client_id

Old question, but I just had this same issue and found a way to get the iframe. It's simply a matter of iterating through the parent window's frames[] array and testing each frame's contentWindow against the window in which your code is running. Example:

var arrFrames = parent.document.getElementsByTagName("IFRAME");
for (var i = 0; i < arrFrames.length; i++) {
  if (arrFrames[i].contentWindow === window) alert("yay!");
}

Or, using jQuery:

parent.$("iframe").each(function(iel, el) {
  if(el.contentWindow === window) alert("got it");
});

This method saves assigning an ID to each iframe, which is good in your case as they are dynamically created. I couldn't find a more direct way, since you can't get the iframe element using window.parent - it goes straight to the parent window element (skipping the iframe). So looping through them seems the only way, unless you want to use IDs.

If this is regarding a class you created, be sure that the class is not nested.

F.e

A.swift

class A {

   class ARelated {

   }
}

calling var b = ARelated() will give 'Use of unresolved identifier: ARelated'.

You can either:

1) separate the classes if wanted on the same file:

A.swift

class A {

}

class ARelated {

}

2) Maintain your same structure and use the enclosing class to get to the subclass:

var b = A.ARelated

There are now multiple ways to mimic this same effect but further tailor the properties based on the use case. As stated above, this works:

.product__specfield_8_arrow { display: inline-block } 

but also

.product__specfield_8_arrow { display: inline-flex } // flex container will be inline
.product__specfield_8_arrow { display: inline-grid } // grid container will be inline
.product__specfield_8_arrow { display: inline-table } // table will be inline-level table

This JSFiddle shows how similar these display properties are in this case.

For a relevant discussion please see this SO post.

If you just want to print a decimal number with 2 digits after decimal point in specific format no matter of locals use something like this

dim d as double = 1.23456789
dim s as string = d.Tostring("0.##", New System.Globalization.CultureInfo("en-US"))

React-Redux connect is used to update store for every actions.

import { connect } from 'react-redux';

const AppContainer = connect(  
  mapStateToProps,
  mapDispatchToProps
)(App);

export default AppContainer;

It's very simply and clearly explained in this blog.

You can clone github project or copy paste the code from that blog to understand the Redux connect.

This worked for me by calling eval on each script content from ajax .done :

$.ajax({}).done(function (data) {      
    $('div#content script').each(function (index, element) { eval(element.innerHTML); 
})  

Note: I didn't write parameters to $.ajax which you have to adjust according to your ajax.

I have changed the code of serge_gubenko and it works better

for (int i = 0; i < dataGrid.Items.Count; i++)
{
    string txt = searchTxt.Text;
    dataGrid.ScrollIntoView(dataGrid.Items[i]);
    DataGridRow row = (DataGridRow)dataGrid.ItemContainerGenerator.ContainerFromIndex(i);
    TextBlock cellContent = dataGrid.Columns[1].GetCellContent(row) as TextBlock;
    if (cellContent != null && cellContent.Text.ToLower().Equals(txt.ToLower()))
    {
        object item = dataGrid.Items[i];
        dataGrid.SelectedItem = item;
        dataGrid.ScrollIntoView(item);
        row.MoveFocus(new TraversalRequest(FocusNavigationDirection.Next));
        break;
    }
}

Have you tried the GNU make documentation? It has a whole section about conditionals with examples.

It looks like it is an extension method (in System.Net.Http.Formatting):

HttpContentExtensions Class

Update:

PM> install-package Microsoft.AspNet.WebApi.Client

According to the System.Net.Http.Formatting NuGet package page, the System.Net.Http.Formatting package is now legacy and can instead be found in the Microsoft.AspNet.WebApi.Client package available on NuGet here.

I don't know if setLogLevel() will return in the final 2.0 version of Retrofit but for now you can use an interceptor for logging.

A good example can found in OkHttp wiki: https://github.com/square/okhttp/wiki/Interceptors

OkHttpClient client = new OkHttpClient();
client.interceptors().add(new LoggingInterceptor());

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("http://www.yourjsonapi.com")
        .addConverterFactory(GsonConverterFactory.create())
        .client(client)
        .build();

Figuring out what path to take requires answering not only CommonsWare's key question of "why" but also the question of "to what?" are you passing it.

The reality is that the only thing that can go through bundles is plain data - everything else is based on interpretations of what that data means or points to. You can't literally pass an object, but what you can do is one of three things:

1) You can break the object down to its constitute data, and if what's on the other end has knowledge of the same sort of object, it can assemble a clone from the serialized data. That's how most of the common types pass through bundles.

2) You can pass an opaque handle. If you are passing it within the same context (though one might ask why bother) that will be a handle you can invoke or dereference. But if you pass it through Binder to a different context it's literal value will be an arbitrary number (in fact, these arbitrary numbers count sequentially from startup). You can't do anything but keep track of it, until you pass it back to the original context which will cause Binder to transform it back into the original handle, making it useful again.

3) You can pass a magic handle, such as a file descriptor or reference to certain os/platform objects, and if you set the right flags Binder will create a clone pointing to the same resource for the recipient, which can actually be used on the other end. But this only works for a very few types of objects.

Most likely, you are either passing your class just so the other end can keep track of it and give it back to you later, or you are passing it to a context where a clone can be created from serialized constituent data... or else you are trying to do something that just isn't going to work and you need to rethink the whole approach.

You can pass the container by reference in order to modify it in the function. What other answers haven’t addressed is that std::vector does not have a push_front member function. You can use the insert() member function on vector for O(n) insertion:

void do_something(int el, std::vector<int> &arr){
    arr.insert(arr.begin(), el);
}

Or use std::deque instead for amortised O(1) insertion:

void do_something(int el, std::deque<int> &arr){
    arr.push_front(el);
}

You could just return an Object as all types are descended from Object.

public Object GetAnything()
{
     Hello hello = new Hello();
     Computer computer = new Computer();
     Radio radio = new Radio();

     return radio; or return computer; or return hello //should be possible?!      
}

You could then cast to its relevant type:

Hello hello = (Hello)GetAnything();

If you didn't know what the type was going to be then you could use the is keyword.

Object obj = GetAnything();
if (obj is Hello) {
    // Do something
}

This being said I would be reluctant to write code like that. It would be much better to have an interface which is implemented by each of your classes.

public ISpeak GetAnything()
{
     Hello hello = new Hello();
     Computer computer = new Computer();
     Radio radio = new Radio();

     return radio; or return computer; or return hello //should be possible?!      
}

interface ISpeak 
{
   void Speak();
}

and have each of your classes implement the interface:

public class Hello : ISpeak
{
    void Speak() {
        Console.WriteLine("Hello");
    }
}

You could then do something like:

GetAnything().Speak();

I separate it, and then use an identity comparison to dictate what is does next.

$("#selectField").change(function(){
  if(this.value === 'textValue1'){ $(".contentClass1").fadeIn(); }
  if(this.value === 'textValue2'){ $(".contentclass2").fadeIn(); }
});

Direct Closure serialisation is not allowed by PHP. But you can use powefull class like PHP Super Closure : https://github.com/jeremeamia/super_closure

This class is really simple to use and is bundled into the laravel framework for the queue manager.

From the github documentation :

$helloWorld = new SerializableClosure(function ($name = 'World') use ($greeting) {
    echo "{$greeting}, {$name}!\n";
});

$serialized = serialize($helloWorld);

The first thing to do is to determine your definition of "line of code" (LOC). In both your question

It counts a line with just one } as a line and he doesn't want that to count as "its not a line, its a style choice"

and in the answers, e.g.,

You can adjust the Lines of Code metrics by ignoring blank and comment-only lines or exclude Javadoc if you want

you can tell that people have different opinions as to what constitutes a line of code. In particular, people are often imprecise about whether they really want the number of lines of code or the number of statements. For example, if you have the following really long line filled with statements, what do you want to report, 1 LOC or hundreds of statements?

{ a = 1; b = 2; if (a==c) b++; /* etc. for another 1000 characters */ }

And when somebody asks you what you are calling a LOC, make sure you can answer, even if it is just "my definition of a LOC is Metrics2's definition". In general, for most commonly formatted code (unlike my example), the popular tools will give numbers fairly similar, so Metrics2, SonarQube, etc. should all be fine, as long as you use them consistently. In other words, don't count the LOC of some code using one tool and compare that value to a later version of that code that was measured with a different tool.

If it gets into the selinux arena you've got a much more complicated issue. It's not a good idea to remove the selinux protection but to embrace it and use the tools that were designed to manage it.

If you are serving content out of /var/www/abc, you can verify the selinux permissions with a Z appended to the normal ls -l command. i.e. ls -laZ will give the selinux context.

To add a directory to be served by selinux you can use the semanage command like this. This will change the label on /var/www/abc to httpd_sys_content_t

semanage fcontext -a -t httpd_sys_content_t /var/www/abc

this will update the label for /var/www/abc

restorecon /var/www/abc 

This answer was taken from unixmen and modified to fit this question. I had been searching for this answer for a while and finally found it so felt like I needed to share somewhere. Hope it helps someone.

Just pass it in like any other parameter:

def a(x):
    return "a(%s)" % (x,)

def b(f,x):
    return f(x)

print b(a,10)

In JQuery:

  $("#id option:selected").prop("selected", false);
  $("#id").multiselect('refresh');

In case you don't have access to functools.partial, you could use a wrapper function for this, as well.

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

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

This makes target() into a function that accepts a lock (or whatever parameters you want to give), and it will return a function that only takes in an iterable as input, but can still use all your other parameters. That's what is ultimately passed in to pool.map(), which then should execute with no problems.

I guess the main question tries to figure out: "when should I use one or the other", or "which should I use", or "Am I using the right one"?

I guess the important point is atan only was intended to feed positive values in a right-upwards direction curve like for time-distance vectors. Cero is always at the bottom left, and thigs can only go up and right, just slower or faster. atan doesn't return negative numbers, so you can't trace things in the 4 directions on a screen just by adding/subtracting its result.

atan2 is intended for the origin to be in the middle, and things can go backwards or down. That's what you'd use in a screen representation, because it DOES matter what direction you want the curve to go. So atan2 can give you negative numbers, because its cero is in the center, and its result is something you can use to trace things in 4 directions.

Short answer:

• EXPOSE is a way of documenting
• --publish (or -p) is a way of mapping a host port to a running container port

Notice below that:

• EXPOSE is related to Dockerfiles ( documenting )
• --publish is related to docker run ... ( execution / run-time )

Exposing and publishing ports

In Docker networking, there are two different mechanisms that directly involve network ports: exposing and publishing ports. This applies to the default bridge network and user-defined bridge networks.

• You expose ports using the EXPOSE keyword in the Dockerfile or the --expose flag to docker run. Exposing ports is a way of documenting which ports are used, but does not actually map or open any ports. Exposing ports is optional.

• You publish ports using the --publish or --publish-all flag to docker run. This tells Docker which ports to open on the container’s network interface. When a port is published, it is mapped to an available high-order port (higher than 30000) on the host machine, unless you specify the port to map to on the host machine at runtime. You cannot specify the port to map to on the host machine when you build the image (in the Dockerfile), because there is no way to guarantee that the port will be available on the host machine where you run the image.

Update October 2019: the above piece of text is no longer in the docs but an archived version is here: docs.docker.com/v17.09/engine/userguide/networking/#exposing-and-publishing-ports

Maybe the current documentation is the below:

Published ports

By default, when you create a container, it does not publish any of its ports to the outside world. To make a port available to services outside of Docker, or to Docker containers which are not connected to the container's network, use the --publish or -p flag. This creates a firewall rule which maps a container port to a port on the Docker host.

and can be found here: docs.docker.com/config/containers/container-networking/#published-ports

Also,

EXPOSE

...The EXPOSE instruction does not actually publish the port. It functions as a type of documentation between the person who builds the image and the person who runs the container, about which ports are intended to be published.

from: Dockerfile reference

Service access when EXPOSE / --publish are not defined:

At @Golo Roden's answer it is stated that::

"If you do not specify any of those, the service in the container will not be accessible from anywhere except from inside the container itself."

Maybe that was the case at the time the answer was being written, but now it seems that even if you do not use EXPOSE or --publish, the host and other containers of the same network will be able to access a service you may start inside that container.

How to test this:

I've used the following Dockerfile. Basically, I start with ubuntu and install a tiny web-server:

FROM ubuntu
RUN apt-get update && apt-get install -y mini-httpd

I build the image as "testexpose" and run a new container with:

docker run --rm -it testexpose bash

Inside the container, I launch a few instances of mini-httpd:

root@fb8f7dd1322d:/# mini_httpd -p 80
root@fb8f7dd1322d:/# mini_httpd -p 8080
root@fb8f7dd1322d:/# mini_httpd -p 8090

I am then able to use curl from the host or other containers to fetch the home page of mini-httpd.

Create a Java Model using Axis wsdl2java (which can take in .xsd files).

Use a database generation tool for Java that takes in a Java Model. Surely something like Hibernate can do this? I wrote my own tool (takes a couple of days, also generates CRUD code in Java too) to save myself time at work, maybe this would be a nice personal project?

Or just do it manually so that you can check everything is correct and good! Database tools are good enough now that you can zip through creating tables for a model without too many problems.

I'm not sure why you'd be getting subscript out of range unless your sheets weren't actually called Sheet1 or Sheet2. When I rename my Sheet2 to Sheet_2, I get that same problem.

In addition, some of your code seems the wrong way about (you paste before selecting the second sheet). This code works fine for me.

Sub OneCell()
    Sheets("Sheet1").Select
    Range("A1:A3").Copy
    Sheets("Sheet2").Select
    Range("b1:b3").Select
    ActiveSheet.Paste
End Sub

If you don't want to know about what the sheets are called, you can use integer indexes as follows:

Sub OneCell()
    Sheets(1).Select
    Range("A1:A3").Copy
    Sheets(2).Select
    Range("b1:b3").Select
    ActiveSheet.Paste
End Sub

In my case, a script was running command while redirecting both stdout and stderr to a file, something like:

cmd > log 2>&1

I needed to update it such that when there is a failure, take some actions based on the error messages. I could of course remove the dup 2>&1 and capture the stderr from the script, but then the error messages won't go into the log file for reference. While the accepted answer from @lhunath is supposed to do the same, it redirects stdout and stderr to different files, which is not what I want, but it helped me to come up with the exact solution that I need:

(cmd 2> >(tee /dev/stderr)) > log

With the above, log will have a copy of both stdout and stderr and I can capture stderr from my script without having to worry about stdout.

Maybe because its 2013-01-29 so +1 month would be 2013-02-29 which doesn't exist so it would be 2013-03-01

You could try

date('m/d/y h:i a',(strtotime('next month',strtotime(date('m/01/y')))));

from the comments on http://php.net/manual/en/function.strtotime.php

To synchronize all of the answers here and elsewhere:

buildscript {
  repositories {
    google() 
    jcenter()
  }
  dependencies {
    classpath 'com.android.tools.build:gradle:3.0.0'

  } }

Make your buildscript in build.gradle look like this. It finds all of them between google and jcenter. Only one of them will not find all of the dependencies as of this answer.

Since socket.io 1.1.0, I use :

io.on('connection', function (socket) {
  console.log('connection :', socket.request.connection._peername);
  // connection : { address: '192.168.1.86', family: 'IPv4', port: 52837 }
}

Edit : Note that this is not part of the official API, and therefore not guaranteed to work in future releases of socket.io.

run this on your master database

You can use library l2i (https://github.com/seriyvolk83/logs2indexeddb) to save all you put into console.log and then invoke

l2i.download();

to download a file with logs.

Using node I have a collection of stuff @stuff and access it like this:

- each stuff in stuffs
  p
    = stuff.sentence

Instead of using this as the accepted answer suggests, use $parent instead. So in your partial1.htmlyou'll have:

<form ng-submit="$parent.addLine()">
    <input type="text" ng-model="$parent.lineText" size="30" placeholder="Type your message here">
</form>

If you want to learn more about the scope in ng-include or other directives, check this out: https://github.com/angular/angular.js/wiki/Understanding-Scopes#ng-include

You should have to look at StringBuilder/StringBuffer which allow you to delete, insert, replace char(s) at specified offset.

Inside file strings.xml define a String resource like this:

<string name="string_to_format">Amount: %1$f  for %2$d days%3$s</string>

Inside your code (assume it inherits from Context) simply do the following:

 String formattedString = getString(R.string.string_to_format, floatVar, decimalVar, stringVar);

(In comparison to the answer from LocalPCGuy or Giovanny Farto M. the String.format method is not needed.)

\includegraphics<1>{A}%
\includegraphics<2>{B}%
\includegraphics<3>{C}%

The % is important. This will keep all the images fixed.

You need:

#include <string.h> /* memset */
#include <unistd.h> /* close */

in your code.

References: POSIX for close, the C standard for memset.

To address the --rebase vs. --merge option:

Let's say you have super repository A and submodule B and want to do some work in submodule B. You've done your homework and know that after calling

git submodule update

you are in a HEAD-less state, so any commits you do at this point are hard to get back to. So, you've started work on a new branch in submodule B

cd B
git checkout -b bestIdeaForBEver
<do work>

Meanwhile, someone else in project A has decided that the latest and greatest version of B is really what A deserves. You, out of habit, merge the most recent changes down and update your submodules.

<in A>
git merge develop
git submodule update

Oh noes! You're back in a headless state again, probably because B is now pointing to the SHA associated with B's new tip, or some other commit. If only you had:

git merge develop
git submodule update --rebase

Fast-forwarded bestIdeaForBEver to b798edfdsf1191f8b140ea325685c4da19a9d437.
Submodule path 'B': rebased into 'b798ecsdf71191f8b140ea325685c4da19a9d437'

Now that best idea ever for B has been rebased onto the new commit, and more importantly, you are still on your development branch for B, not in a headless state!

(The --merge will merge changes from beforeUpdateSHA to afterUpdateSHA into your working branch, as opposed to rebasing your changes onto afterUpdateSHA.)

It's probably a typo. Look for the places in your code where you call [schema].[TableName] (basically anywhere you reference a field) and make sure everything is spelled correctly.

Personally, I try to avoid this by using aliases for all my tables. It helps tremendously when you can shorten a long table name to an acronym of it's description (i.e. WorkOrderParts -> WOP), and also makes your query more readable.

Edit: As an added bonus, you'll save TONS of keystrokes when all you have to type is a three or four-letter alias vs. the schema, table, and field names all together.

The following should work. The lambda function filter out the duplicated words.

inputs=[]
input = raw_input("Word: ").strip()
while input:
    inputs.append(input)
    input = raw_input("Word: ").strip()
uniques=reduce(lambda x,y: ((y in x) and x) or x+[y], inputs, [])
print 'There are', len(uniques), 'unique words'

Maybe not that good but I've figured this:

def order_dic(dic):
    ordered_dic={}
    key_ls=sorted(dic.keys())
    for key in key_ls:
        ordered_dic[key]=dic[key]
    return ordered_dic

Total online memory

Calculate the total online memory using the sys-fs.

totalmem=0;
for mem in /sys/devices/system/memory/memory*; do
  [[ "$(cat ${mem}/online)" == "1" ]] \
    && totalmem=$((totalmem+$((0x$(cat /sys/devices/system/memory/block_size_bytes)))));
done

#one-line code
totalmem=0; for mem in /sys/devices/system/memory/memory*; do [[ "$(cat ${mem}/online)" == "1" ]] && totalmem=$((totalmem+$((0x$(cat /sys/devices/system/memory/block_size_bytes))))); done

echo ${totalmem} bytes
echo $((totalmem/1024**3)) GB

Example output for 4 GB system:

4294967296 bytes
4 GB

Explanation

/sys/devices/system/memory/block_size_bytes

Number of bytes in a memory block (hex value). Using 0x in front of the value makes sure it's properly handled during the calculation.

/sys/devices/system/memory/memory*

Iterating over all available memory blocks to verify they are online and add the calculated block size to totalmem if they are.

[[ "$(cat ${mem}/online)" == "1" ]] &&

You can change or remove this if you prefer another memory state.

If the instance variables are same as the variables that are declared in the constructor then we use "this" to assign data.

class Example{
     int assign;// instance variable

     Example(int assign){ // variable inside constructor
          this.assign=assign;
     }
}

Hope this helps.

My answer is little late but simple; but may help someone in future; I did experiment with angular versions such as 4.4.3, 5.1+, 6.x, 7.x, 8.x, 9.x and 10.x using $event (latest at the moment)

Template:

<select (change)="onChange($event)">
    <option *ngFor="let v of values" [value]="v.id">{{v.name}}</option>
</select>

TS

export class MyComponent {
  public onChange(event): void {  // event will give you full breif of action
    const newVal = event.target.value;
    console.log(newVal);
  }
}

the method i Use for creating roles is below, assigning them to users in code is also listed. the below code does be in "configuration.cs" in the migrations folder.

string [] roleNames = { "role1", "role2", "role3" };
var RoleManager = new RoleManager<IdentityRole>(new RoleStore<IdentityRole>(context));

                IdentityResult roleResult;
                foreach(var roleName in roleNames)
                {
                    if(!RoleManager.RoleExists(roleName))
                    {
                        roleResult = RoleManager.Create(new IdentityRole(roleName));
                    }
                }
                var UserManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(context));
                UserManager.AddToRole("user", "role1");
                UserManager.AddToRole("user", "role2");
                context.SaveChanges();

import java.io.RandomAccessFile;

try this

@media handheld{
    #title_message { display: none; }

Adding the following two lines in the script solved the issue for me.

# !/usr/bin/python
# coding=utf-8

Hope it helps !

The two structs are different. When you initialize the first struct, about 40 bytes of memory are allocated. When you initialize the second struct, about 10 bytesof memory are allocated. (Actual amount is architecture dependent)

You can use the string literals (string constants) to initalize character arrays. This is why

person p = {"John", "Doe",30};

works in the first example.

You cannot assign (in the conventional sense) a string in C.

The string literals you have ("John") are loaded into memory when your code executes. When you initialize an array with one of these literals, then the string is copied into a new memory location. In your second example, you are merely copying the pointer to (location of) the string literal. Doing something like:

char* string = "Hello";
*string = 'C'

might cause compile or runtime errors (I am not sure.) It is a bad idea because you are modifying the literal string "Hello" which, for example on a microcontroler, could be located in read-only memory.

If the select is show results one have to use this:

$('#yourSelect2ControlId').select2("close").parent().hide();

it closes the search results box and then set control unvisible

You can use Linq in case you are using .NET 3.5 or later:

 test = test.Where(x => !string.IsNullOrEmpty(x)).ToArray();

If you can't use Linq then you can do it like this:

var temp = new List<string>();
foreach (var s in test)
{
    if (!string.IsNullOrEmpty(s))
        temp.Add(s);
}
test = temp.ToArray();

When people say don't put logic in views, they're usually referring to business logic, not rendering logic. In my humble opinion, I think using @foreach in views is perfectly fine.

Here is a check list for you:

1) Is your app published? (Production APK is not required for publishing)

2) Did your alpha/beta testers "Accept invitation" to Google+ community or Google group?

3) Are your alpha/beta testers logged in their Google+ account?

4) Are your alpha/beta testers using your link from Google Play developer console? It has format like this: https://play.google.com/apps/testing/com.yourdomain.package

I know executing from sp and insert into temp table or table variable would be an option but I don't think that's your requirement. As per your requirement this below query statement should work:

Declare @sql nvarchar(max)
Set @sql='SELECT   col1, col2 FROM OPENROWSET(''SQLNCLI'', ''Server=(local);uid=test;pwd=test'',
     ''EXEC MyStoredProc ''''param1'''', ''''param2'''''')'
 Exec(@sql)

if you have trusted connection then use this below query statement :

Declare @sql nvarchar(max)
Set @sql='SELECT   col1, col2 FROM OPENROWSET(''SQLNCLI'', ''Server=(local);Trusted_Connection=yes;'',
     ''EXEC MyStoredProc ''''param1'''', ''''param2'''''')'
 Exec(@sql)

if you are getting error to run the above statement then just run this statement below:

sp_configure 'Show Advanced Options', 1
GO
RECONFIGURE
GO
sp_configure 'Ad Hoc Distributed Queries', 1
GO
RECONFIGURE
GO

I hope this will help someone who will have faced this kind of similar problem. If someone would to try with temp table or table variable that should be like this below but in this scenario you should to know how many columns your sp is returning then you should create that much columns in temp table or table variable:

--for table variable 
Declare @t table(col1 col1Type, col2 col2Type)
insert into @t exec MyStoredProc 'param1', 'param2'
SELECT col1, col2 FROM @t

--for temp table
create table #t(col1 col1Type, col2 col2Type)
insert into #t exec MyStoredProc 'param1', 'param2'
SELECT col1, col2 FROM #t

I know you said you didn't want to read the file in by hand, but this is pretty easy

public class FooTest
{
    private BufferedReader in = null;

    @Before
    public void setup()
        throws IOException
    {
        in = new BufferedReader(
            new InputStreamReader(getClass().getResourceAsStream("/data.txt")));
    }

    @After
    public void teardown()
        throws IOException
    {
        if (in != null)
        {
            in.close();
        }

        in = null;
    }

    @Test
    public void testFoo()
        throws IOException
    {
        String line = in.readLine();

        assertThat(line, notNullValue());
    }
}

All you have to do is ensure the file in question is in the classpath. If you're using Maven, just put the file in src/test/resources and Maven will include it in the classpath when running your tests. If you need to do this sort of thing a lot, you could put the code that opens the file in a superclass and have your tests inherit from that.

As duplicate comment keys are removed running package.json tools (npm, yarn, etc.), I came to using a hashed version which allows for better reading as multiple lines and keys like:

"//": {
  "alpaca": "we use the bootstrap version",
  "eonasdan-bootstrap-datetimepicker": "instead of bootstrap-datetimepicker",
  "moment-with-locales": "is part of moment"
},

which is 'valid' according to my IDE as a root key, but within dependencies it complains expecting a string value.

First convert it into bytes using getBytes() function and then convert it into hex usign this :

private static String hex(byte[] bytes) {
    StringBuilder sb = new StringBuilder();
    for (int i=0; i<bytes.length; i++) {
        sb.append(String.format("%02X ",bytes[i]));
    }
    return sb.toString();
}

You've already discovered the simplest way to specify a shallow clone in Git-SVN, by specifying the SVN revision number that you want to start your clone at ( -r$REV:HEAD).

For example: git svn clone -s -r1450:HEAD some/svn/repo

Git's data structure is based on pointers in a directed acyclic graph (DAG), which makes it trivial to walk back n commits. But in SVN ( and therefore in Git-SVN) you will have to find the revision number yourself.

You can't. You have to have a separate div that is just that background, so that you can only apply the opacity to that.

I tried doing this recently, and since I was already using jQuery, I found the following to be the least hassle:

1. Create the two different divs. They'll be siblings, not contained in each other or anything.
2. Give the text div a solid background color, because that will be the JavaScript-less default.
3. Use jQuery to get the text div's height, and apply it to the background div.

I'm sure there's some kind of CSS ninja way to do all this with only floats or something, but I didn't have the patience to figure it out.

jQuery's Sizzle selector engine can use querySelectorAll if it's available. It also smooths out inconsistencies between browsers to achieve uniform results. If you don't want to use all of jQuery, you could just use Sizzle separately. This is a pretty fundamental wheel to invent.

Here's some cherry-pickings from the source that show the kind of things jQuery(w/ Sizzle) sorts out for you:

Safari quirks mode:

if ( document.querySelectorAll ) {
  (function(){
    var oldSizzle = Sizzle,
      div = document.createElement("div"),
      id = "__sizzle__";

    div.innerHTML = "<p class='TEST'></p>";

    // Safari can't handle uppercase or unicode characters when
    // in quirks mode.
    if ( div.querySelectorAll && div.querySelectorAll(".TEST").length === 0 ) {
      return;
    }

If that guard fails it uses it's a version of Sizzle that isn't enhanced with querySelectorAll. Further down there are specific handles for inconsistencies in IE, Opera, and the Blackberry browser.

  // Check parentNode to catch when Blackberry 4.6 returns
  // nodes that are no longer in the document #6963
  if ( elem && elem.parentNode ) {
    // Handle the case where IE and Opera return items
    // by name instead of ID
    if ( elem.id === match[3] ) {
      return makeArray( [ elem ], extra );
    }

  } else {
    return makeArray( [], extra );
  }

And if all else fails it will return the result of oldSizzle(query, context, extra, seed).

This should do it:

#!/usr/local/cpython-2.7/bin/python  # offer users choice for how large of a song list they want to create # in order to determine (roughly) how many songs to copy print "\nHow much space should the random song list occupy?\n" print "1. 100Mb" print "2. 250Mb\n"  tSizeAns = int(raw_input())  if tSizeAns == 1:     tSize = "100Mb" elif tSizeAns == 2:     tSize = "250Mb" else:     tSize = "100Mb"    # in case user fails to enter either a 1 or 2  print "\nYou  want to create a random song list that is {}.".format(tSize) 

BTW, in case you're open to moving to Python 3.x, the differences are slight:

#!/usr/local/cpython-3.3/bin/python  # offer users choice for how large of a song list they want to create # in order to determine (roughly) how many songs to copy print("\nHow much space should the random song list occupy?\n") print("1. 100Mb") print("2. 250Mb\n")  tSizeAns = int(input())  if tSizeAns == 1:     tSize = "100Mb" elif tSizeAns == 2:     tSize = "250Mb" else:     tSize = "100Mb"    # in case user fails to enter either a 1 or 2  print("\nYou want to create a random song list that is {}.".format(tSize)) 

HTH

If you are willing to change your uri, you could also use PathVariable.

@RequestMapping(value="/mapping/foo/{foo}/{bar}", method=RequestMethod.GET)
public String process(@PathVariable String foo,@PathVariable String bar) {
    //Perform logic with foo and bar
}

NB: The first foo is part of the path, the second one is the PathVariable

Now NgForm supports two methods: .reset() vs .resetForm() the latter also changes the submit state of the form to false reverting form and its controls to initial states.

One recursive for the fun.

Not the most elegant answer, but should work everywhere:

import os

def split_path(path):
    head = os.path.dirname(path)
    tail = os.path.basename(path)
    if head == os.path.dirname(head):
        return [tail]
    return split_path(head) + [tail]

Maybe your changes are not lost. Check "git reflog"

I quote the article below:

"Basically every action you perform inside of Git where data is stored, you can find it inside of the reflog. Git tries really hard not to lose your data, so if for some reason you think it has, chances are you can dig it out using git reflog"

See details:

http://gitready.com/intermediate/2009/02/09/reflog-your-safety-net.html

I would expect either:

// Makes sure item is at newIndex after the operation
T item = list[oldIndex];
list.RemoveAt(oldIndex);
list.Insert(newIndex, item);

... or:

// Makes sure relative ordering of newIndex is preserved after the operation, 
// meaning that the item may actually be inserted at newIndex - 1 
T item = list[oldIndex];
list.RemoveAt(oldIndex);
newIndex = (newIndex > oldIndex ? newIndex - 1, newIndex)
list.Insert(newIndex, item);

... would do the trick, but I don't have VS on this machine to check.

There is apparently a lot of misunderstanding about this!

The only practical difference between KeyDown and KeyPress is that KeyPress relays the character resulting from a keypress, and is only called if there is one.

In other words, if you press A on your keyboard, you'll get this sequence of events:

1. KeyDown: KeyCode=Keys.A, KeyData=Keys.A, Modifiers=Keys.None
2. KeyPress: KeyChar='a'
3. KeyUp: KeyCode=Keys.A

But if you press Shift+A, you'll get:

1. KeyDown: KeyCode=Keys.ShiftKey, KeyData=Keys.ShiftKey, Shift, Modifiers=Keys.Shift
2. KeyDown: KeyCode=Keys.A, KeyData=Keys.A | Keys.Shift, Modifiers=Keys.Shift
3. KeyPress: KeyChar='A'
4. KeyUp: KeyCode=Keys.A
5. KeyUp: KeyCode=Keys.ShiftKey

If you hold down the keys for a while, you'll get something like:

1. KeyDown: KeyCode=Keys.ShiftKey, KeyData=Keys.ShiftKey, Shift, Modifiers=Keys.Shift
2. KeyDown: KeyCode=Keys.ShiftKey, KeyData=Keys.ShiftKey, Shift, Modifiers=Keys.Shift
3. KeyDown: KeyCode=Keys.ShiftKey, KeyData=Keys.ShiftKey, Shift, Modifiers=Keys.Shift
4. KeyDown: KeyCode=Keys.ShiftKey, KeyData=Keys.ShiftKey, Shift, Modifiers=Keys.Shift
5. KeyDown: KeyCode=Keys.ShiftKey, KeyData=Keys.ShiftKey, Shift, Modifiers=Keys.Shift
6. KeyDown: KeyCode=Keys.A, KeyData=Keys.A | Keys.Shift, Modifiers=Keys.Shift
7. KeyPress: KeyChar='A'
8. KeyDown: KeyCode=Keys.A, KeyData=Keys.A | Keys.Shift, Modifiers=Keys.Shift
9. KeyPress: KeyChar='A'
10. KeyDown: KeyCode=Keys.A, KeyData=Keys.A | Keys.Shift, Modifiers=Keys.Shift
11. KeyPress: KeyChar='A'
12. KeyDown: KeyCode=Keys.A, KeyData=Keys.A | Keys.Shift, Modifiers=Keys.Shift
13. KeyPress: KeyChar='A'
14. KeyDown: KeyCode=Keys.A, KeyData=Keys.A | Keys.Shift, Modifiers=Keys.Shift
15. KeyPress: KeyChar='A'
16. KeyUp: KeyCode=Keys.A
17. KeyUp: KeyCode=Keys.ShiftKey

Notice that KeyPress occurs in between KeyDown and KeyUp, not after KeyUp, as many of the other answers have stated, that KeyPress is not called when a character isn't generated, and that KeyDown is repeated while the key is held down, also contrary to many of the other answers.

Examples of keys that do not directly result in calls to KeyPress:

• Shift, Ctrl, Alt
• F1 through F12
• Arrow keys

Examples of keys that do result in calls to KeyPress:

• A through Z, 0 through 9, etc.
• Spacebar
• Tab (KeyChar='\t', ASCII 9)
• Enter (KeyChar='\r', ASCII 13)
• Esc (KeyChar='\x1b', ASCII 27)
• Backspace (KeyChar='\b', ASCII 8)

For the curious, KeyDown roughly correlates to WM_KEYDOWN, KeyPress to WM_CHAR, and KeyUp to WM_KEYUP. WM_KEYDOWN can be called fewer than the the number of key repeats, but it sends a repeat count, which, IIRC, WinForms uses to generate exactly one KeyDown per repeat.

Spaces in the Commend Prompt (in a VBA Shell command code line)

I had a very similar problem which ended up being a space in the command prompt when automating via VBA to get the contents from the command window into a text file. This Thread was one of many I caught along the way that didn’t quite get me the solution.

So this may help others with a similar problem: Since the syntax with quotes is always difficult to get right , I think showing some specific examples is always useful. The additional problem you get using the command prompt in VBA via the Shell thing, is that the code line often won’t error when something goes wrong: in fact a blink of the black commend window misleads into thinking something was done.

As example… say I have a Folder, with a text file in it like at

C:\Alans Folder\test1.txt ( https://imgur.com/FELSdB6 )

The space there in the folder name gives the problem.

Something like this would work, assuming the Folder, AlansFolder, exists

Sub ShellBlackCommandPromptWindowAutomatingCopyingWindowContent()
 Shell "cmd.exe /c ""ipconfig /all > C:\AlansFolder\test1.txt"""
End Sub

This won’t work. (It won’t error).

Sub ShellBlackCommandPromptWindowAutomatingCopyingWindowContent()
 Shell "cmd.exe /c ""ipconfig /all > C:\Alans Folder\test1.txt"""
End Sub

Including quote pairs around the path will make it work

Sub ShellBlackCommandPromptWindowAutomatingCopyingWindowContent()
 Shell "cmd.exe /c ""ipconfig /all > ""C:\Alans Folder\test1.txt"""""
End Sub

( By the way, if the text file does not exist, then it will be made).

With the benefit of hindsight, we can see that my solution does tie up approximately with some already given..

Converting that code line to a manual given command we would have

ipconfig /all > "C:\Alans Folder\test1.txt"

That seems to work

This works also

ipconfig /all > C:\AlansFolder\test1.txt

This doesn’t

ipconfig /all > C:\Alans Folder\test1.txt

This final form also works and ties up with the solution from sacra ….” You have to add quotation marks around each path and also enclose the whole command in quotation marks “ …..

cmd.exe /c "ipconfig /all > "C:\Alans Folder\test1.txt""

The result is truncated to the maximum length that is given by the group_concat_max_len system variable, which has a default value of 1024 characters, so we first do:

SET group_concat_max_len=100000000;

and then, for example:

SELECT pub_id,GROUP_CONCAT(cate_id SEPARATOR ' ') FROM book_mast GROUP BY pub_id

Maybe combining some javascript and PHP could achieve the trick

<?php
$string = '<script>';
$string .= 'if ( /Opera|OPR\/|Puffin|Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent)) { ';
$string .= '        alert("CELL")';
$string .= '    } else {';
$string .= '        alert("NON CELL")';
$string .= '    }       ';  
$string .= '</script>'; 
echo $string;
?>

I used that with plain javascript also instead

First, stop your Tomcat, then double click your server, click Server Locations and check Use Tomcat Installation (takes control of Tomcat installation).

Before changing your react native package name! please make a backup of MainActivity.java and MainApplication.java file. Because this lib remove your MainActivity.java and MainApplication.java.

after doing this you can simply use react-native-rename npm package.

Install

npm install react-native-rename -g

Then from the root of your React Native project execute the following

react-native-rename "new_project_name" -b com.mycompany.newprojectname

finally you can check it out your new package name in your AndroidManifest.xml. Don't forgot to rename the package name in your MainActivity.java and MainApplication.java .

Thank you.

So you have "a list of tuples", let me assume that you are manipulating some 2-dimension matrix, and, in this case, one convenient interface to accomplish what you need is the one numpy provides.

Say you have an array arr = numpy.array([[1, 2], [3, 4], [5, 6]]), you can use arr[:, 0] to get a new array of all the first elements in each "tuple".

In our case it turned out that the error happened because we have a custom filter in our application which does HttpServletResponse sendRedirect() to other url.

For some reason, the redirection is not closing the keep-alive status of the connection, hence the timeout exception.

We checked with Tomcat Docs and when we disabled the maxKeepAliveRequests by setting it's value to 1 and the error stopped showing up.

For now we do not have the actual solution to the error.

Try to remove multidex from default config and check the build error log. If that log is some relatable with INotification class. Use this in android{}

mod_log_forensic is what you want, but it may not be included/available with your Apache install by default.

Here is how to use it.

LoadModule log_forensic_module /usr/lib64/httpd/modules/mod_log_forensic.so 
<IfModule log_forensic_module> 
ForensicLog /var/log/httpd/forensic_log 
</IfModule> 

This is handy for alpha sorts of all sizes. Pass it the indexes you want to sort by, in order, as arguments.

Array.prototype.deepSortAlpha= function(){
    var itm, L=arguments.length, order=arguments;

    var alphaSort= function(a, b){
        a= a.toLowerCase();
        b= b.toLowerCase();
        if(a== b) return 0;
        return a> b? 1:-1;
    }
    if(!L) return this.sort(alphaSort);

    this.sort(function(a, b){
        var tem= 0,  indx=0;
        while(tem==0 && indx<L){
            itm=order[indx];
            tem= alphaSort(a[itm], b[itm]); 
            indx+=1;        
        }
        return tem;
    });
    return this;
}

var arr= [[ "Nilesh","Karmshil"], ["Pranjal","Deka"], ["Susants","Ghosh"],
["Shiv","Shankar"], ["Javid","Ghosh"], ["Shaher","Banu"], ["Javid","Rashid"]];

arr.deepSortAlpha(1,0);

As you've noticed, you have no selectivity to your update statement so it is updating your entire table. If you want to update specific rows (ie where the IDs match) you probably want to do a coordinated subquery.

However, since you are using Oracle, it might be easier to create a materialized view for your query table and let Oracle's transaction mechanism handle the details. MVs work exactly like a table for querying semantics, are quite easy to set up, and allow you to specify the refresh interval.

I used the CSS in the accepted answer here for my responsive YouTube videos - worked great right up until YouTube updated their system around the start of August 2015. The videos on YouTube are the same dimensions but for whatever reason the CSS in the accepted answer now letterboxes all our videos. Black bands across top and bottom.

I've tickered around with the sizes and settled on getting rid of the top padding and changing the bottom padding to 56.45%. Seems to look good.

.videowrapper {
    position: relative;
    padding-bottom: 56.45%;
    height: 0;
}

From WWDC 2015 there is a session on Implementing UI Designs in Interface Builder. Around the 32min mark he says that you always want to make your @IBOutlet strong.

Just add the following code:

You can look into Windows installed folder from here of your pc path:

     slide: function(e,ui){
                 $('.user-text').css('transform', 'scale(' + ui.value + ')')

            }                
  });

Update 2019 - Bootstrap 4

I'm revisiting this Bootstrap customization question for 4.x, which now utilizes SASS instead of LESS. In general, there are 2 ways to customize Bootstrap...

1. Simple CSS Overrides

One way to customize is simply using CSS to override Bootstrap CSS. For maintainability, CSS customizations are put in a separate custom.css file, so that the bootstrap.css remains unmodified. The reference to the custom.css follows after the bootstrap.css for the overrides to work...

<link rel="stylesheet" type="text/css" href="css/bootstrap.min.css">
<link rel="stylesheet" type="text/css" href="css/custom.css">

Just add whatever changes are needed in the custom CSS. For example...

    /* remove rounding from cards, buttons and inputs */
    .card, .btn, .form-control {
        border-radius: 0;
    }

Before (bootstrap.css)

After (with custom.css)

When making customizations, you should understand CSS Specificity. Overrides in the custom.css need to use selectors that are the same specificity as (or more specific) the bootstrap.css.

Note there is no need to use !important in the custom CSS, unless you're overriding one of the Bootstrap Utility classes. CSS specificity always works for one CSS class to override another.

2. Customize using SASS

If you're familiar with SASS (and you should be to use this method), you can customize Bootstrap with your own custom.scss. There is a section in the Bootstrap docs that explains this, however the docs don't explain how to utilize existing variables in your custom.scss. For example, let's change the body background-color to #eeeeee, and change/override the blue primary contextual color to Bootstrap's $purple variable...

/* custom.scss */    

/* import the necessary Bootstrap files */
@import "bootstrap/functions";
@import "bootstrap/variables";

/* -------begin customization-------- */   

/* simply assign the value */ 
$body-bg: #eeeeee;

/* use a variable to override primary */
$theme-colors: (
  primary: $purple
);
/* -------end customization-------- */  

/* finally, import Bootstrap to set the changes! */
@import "bootstrap";

This also works to create new custom classes. For example, here I add purple to the theme colors which creates all the CSS for btn-purple, text-purple, bg-purple, alert-purple, etc...

/* add a new purple custom color */
$theme-colors: (
  purple: $purple
);

https://www.codeply.com/go/7XonykXFvP

With SASS you must @import bootstrap after the customizations to make them work! Once the SASS is compiled to CSS (this must be done using a SASS compiler node-sass, gulp-sass, npm webpack, etc..), the resulting CSS is the customized Bootstrap. If you're not familiar with SASS, you can customize Bootstrap using a tool like this theme builder I created.

Custom Bootstrap Demo (SASS)

Note: Unlike 3.x, Bootstrap 4.x doesn't offer an official customizer tool. You can however, download the grid only CSS or use another 4.x custom build tool to re-build the Bootstrap 4 CSS as desired.

Basically you cannot but you can bypass the situation.

The correct way to add the foreign key constraint to an existing table is the following command.

db.execSQL("alter table child add column newCol integer REFERENCES parent(parent_Id)");

Then copy the parent_Id data to the newCol and then delete the Parent_Id column. Hence, no need for temporary table.

Here is something that i have been trying.(Insertion sort- not the best way to sort but does the work)

def sort(list):
    for index in range(1,len(list)):
        value = list[index]
        i = index-1
        while i>=0:
            if value < list[i]:
                list[i+1] = list[i]
                list[i] = value
                i -= 1
            else:
                break

If by "empty" you mean undefined, it is the way ng-expressions are interpreted. Then, you could use :

<a ng-if="!item.photo" href="#/details/{{item.id}}"><img src="/img.jpg" class="img-responsive"></a>

It is also possible to review changes between two commits for a specific file.

git diff <commit_Id_1> <commit_Id_2> some_dir/file.txt

In a Spring project you can use

UriComponentsBuilder.fromHttpRequest(new ServletServerHttpRequest(request)).build().toUriString()

In C, this is done using arguments passed to your main() function:

int main(int argc, char *argv[])
{
    int i = 0;
    for (i = 0; i < argc; i++) {
        printf("argv[%d] = %s\n", i, argv[i]);
    }
    return 0;
}

More information can be found online such as this Arguments to main article.

The solution provided by ebeneditos works perfectly.

But if you have cv2.imwrite() in several sections of a large code snippet and you want to change the path where the images get saved, you will have to change the path at every occurrence of cv2.imwrite() individually.

As Soltius stated, here is a better way. Declare a path and pass it as a string into cv2.imwrite()

import cv2
import os
img = cv2.imread('1.jpg', 1)
path = 'D:/OpenCV/Scripts/Images'
cv2.imwrite(os.path.join(path , 'waka.jpg'), img)
cv2.waitKey(0)

Now if you want to modify the path, you just have to change the path variable.

According to Extensible Messaging and Presence Protocol (Wikipedia), the standard TCP port for the server is 5222.

The client would presumably use the same ports as the messaging protocol, but can also use http (port 80) and https (port 443) for message delivery. These have the advantage of working for users behind firewalls, so your network admin should not need to get involved.

For Kotlin devs: To allow Hibernate to inherit from the @Entity types that you want to be lazy-loadable they have to be inheritable/open, which they in Kotlin by default are not. To work around this issue we can make use of the all-open compiler plugin and instruct it to also handle the JPA annotations by adding this to our build.gradle:

allOpen {
   annotation("javax.persistence.Entity")
   annotation("javax.persistence.MappedSuperclass")
   annotation("javax.persistence.Embeddable")
}

If you are using Kotlin and Spring like me, you are most probably also using the kotlin-jpa/no-args and kotlin-spring/all-open compiler plugins already. However, you will still need to add the above lines, as that combination of plugins neither makes such classes open.

Instead of bar use self.bar or Foo.bar. Assigning to Foo.bar will create a static variable, and assigning to self.bar will create an instance variable.

Every programming language has its own set of rules and conventions for the kinds of names that you're allowed to use, and the Java programming language is no different. The rules and conventions for naming your variables can be summarized as follows:

• Variable names are case-sensitive. A variable's name can be any legal identifier — an unlimited-length sequence of Unicode letters and digits, beginning with a letter, the dollar sign "$", or the underscore character "_". The convention, however, is to always begin your variable names with a letter, not "$" or "_". Additionally, the dollar sign character, by convention, is never used at all. You may find some situations where auto-generated names will contain the dollar sign, but your variable names should always avoid using it. A similar convention exists for the underscore character; while it's technically legal to begin your variable's name with "_", this practice is discouraged. White space is not permitted.

• Subsequent characters may be letters, digits, dollar signs, or underscore characters. Conventions (and common sense) apply to this rule as well. When choosing a name for your variables, use full words instead of cryptic abbreviations. Doing so will make your code easier to read and understand. In many cases it will also make your code self-documenting; fields named cadence, speed, and gear, for example, are much more intuitive than abbreviated versions, such as s, c, and g. Also keep in mind that the name you choose must not be a keyword or reserved word.

• If the name you choose consists of only one word, spell that word in all lowercase letters. If it consists of more than one word, capitalize the first letter of each subsequent word. The names gearRatio and currentGear are prime examples of this convention. If your variable stores a constant value, such as static final int NUM_GEARS = 6, the convention changes slightly, capitalizing every letter and separating subsequent words with the underscore character. By convention, the underscore character is never used elsewhere.

select GROUP_CONCAT(stat SEPARATOR ' ') from (select concat('KILL ',id,';') as stat from information_schema.processlist) as stats;

Then copy and paste the result back into the terminal. Something like:

KILL 2871; KILL 2879; KILL 2874; KILL 2872; KILL 2866;

Just a side note for anyone that stumbles onto this same inquiry... My Operating System is 64 bit - so of course I downloaded the 64 bit MySQL driver... however, my Office applications are 32 bit... Once I downloaded the 32 bit version, the error went away and I could move forward.

If I understand correctly, you need a regex statement that checks for at least 6 characters (letters & numbers)?

/[0-9a-zA-Z]{6,}/

I was using Angular 8 and was .NET core API. I add the following in my service web.config file. That resolve my error.

<system.webServer>
  <modules runAllManagedModulesForAllRequests="false">
    <remove name="WebDAVModule" />
  </modules>
</system.webServer>

I had a similar problem, and being the newbie that I am it took me a while to figure out but I learned the user must have a login in SSMS. I created the logins with the following parameters:

• Under Server Roles - check sysadmin
• Under User Mapping - I selected the database and the report server. For each I checked datareader and datawriter
• Under Securables - I checked anything that would allow the user to connect to the database and view anything
• I also found that one of the existing logins had denydatareader and denydatawriter checked. Once I removed these it worked.

I'm not saying this is the best way to do it, just what worked for me. Hope this helps

A version of John's answer above that removes the pesky NA's:

stderr <- function(x, na.rm=FALSE) {
  if (na.rm) x <- na.omit(x)
  sqrt(var(x)/length(x))
}

1. File -> Import -> Existing Project into Workspace
2. Browse for that directory.

Alternative: Check out the code in SVN to some folder

1. Create a new folder in windows
2. In eclipse File -> switchWorkspace -> newFolderName
3. close the welcome window in eclipse
4. In eclipse File -> Import -> Existing project into workspce-> select root dir -> browse and show the svn checkout folder

Use git reflog to find the hashes of previously checked out commits.

A shortcut command to get to your last checked out branch (not sure if this work correctly with detached HEAD and intermediate commits though) is git checkout -
