Edit: I just realized the warning is referencing a component called TextLayerInternal. That's likely where your bug is. The rest of this is still relevant, but it might not fix your problem.

1) Getting the instance of a component for this warning is tough. It looks like there is some discussion to improve this in React but there currently is no easy way to do it. The reason it hasn't been built yet, I suspect, is likely because components are expected to be written in such a way that setState after unmount isn't possible no matter what the state of the component is. The problem, as far as the React team is concerned, is always in the Component code and not the Component instance, which is why you get the Component Type name.

That answer might be unsatisfactory, but I think I can fix your problem.

2) Lodashes throttled function has a cancel method. Call cancel in componentWillUnmount and ditch the isComponentMounted. Canceling is more "idiomatically" React than introducing a new property.

Although it's a long time after this question is being asked since I was searching so much for the same problem and couldn't find the extant solutions helpful, I write what fixed my trouble for anyone with the same issue: The point is, Jupyter should be installed in your virtual environment, meaning, after activating the tensorflow environment, run the following in the command prompt (in tensorflow virtual environment):

conda install jupyter
jupyter notebook

and then the jupyter will pop up.

use this URL : "https://twitter.com/(userName)/profile_image?size=original"

If you are using TWitter SDK you can get the user name when logged in, with TWTRAPIClient, using TWTRAuthSession.

This is the code snipe for iOS:

if let twitterId = session.userID{
   let twitterClient = TWTRAPIClient(userID: twitterId)
   twitterClient.loadUser(withID: twitterId) {(user, error) in
       if let userName = user?.screenName{
          let url = "https://twitter.com/\(userName)/profile_image?size=original")
       }
   }
}

I had all kinds of problems figuring this out as well. I don't know if it will provide exactly what you need, but I downloaded my notebook as an HTML file, then pulled it up in my Chrome browser, and then printed it as a PDF file, which I saved. It captured all my code, text and graphs. It was good enough for what I needed.

For more configurations, I strongly advise the excellent GitLab Markdown Guide.
You can also check the less detailed GitHub basic formatting syntax.
You can compare Markdown implementations using Babelmark.

Useful hints :

• to force a newline, put two spaces at the end of the line;

• to escape special characters, use \.

Let me share what worked for me:

1. When we do "mvn clean" - we are cleaning old compiled classes please lgo to ocation "your project directroy -> target " you will find this folder is getting cleaned because that's where MVN places it's compiled artifacts

2. Since it's already a MAVEN project then go to your project folder and open in command prompt. And issue "mvn clean" and then "mvn test" -> "mvn test" command will place all the compiled files under proper folders and then you can run your tests through TestNG or MAVEN itself.

3. Make sure you set up "M2_HOME" or "MAVEN_HOME" to your env path , sometime "MAVEN_HOME" doesn't work so add "M2_HOME" as well (google it for this set up)

Above suggestions worked for me so I wanted to share, good luck

You can use python-docx2txt which is adapted from python-docx but can also extract text from links, headers and footers. It can also extract images.

You are missing spring-security-web-3.1.X.RELEASE.jar from your classpath

When you generate a JAXB model from an XML Schema, global elements that correspond to named complex types will have that metadata captured as an @XmlElementDecl annotation on a create method in the ObjectFactory class. Since you are creating the JAXBContext on just the DocumentType class this metadata isn't being processed. If you generated your JAXB model from an XML Schema then you should create the JAXBContext on the generated package name or ObjectFactory class to ensure all the necessary metadata is processed.

Example solution:

JAXBContext jaxbContext = JAXBContext.newInstance(my.generatedschema.dir.ObjectFactory.class);
DocumentType documentType = ((JAXBElement<DocumentType>) jaxbContext.createUnmarshaller().unmarshal(inputStream)).getValue();

You have indented part of your code in settings.py:

# Uncomment the next line to enable the admin:
     'django.contrib.admin',
    # Uncomment the next line to enable admin documentation:
    #'django.contrib.admindocs',
     'tinymce',
     'sorl.thumbnail',
     'south',
     'django_facebook',
     'djcelery',
     'devserver',
     'main',

Therefore, it is giving you an error.

I had the same error with python manage.py runserver.

For me, it turned out that it was because of a stale compiled binary (.pyc) file. After deleting all such files in my project, server started running again. :)

So if you get this error, out of nowhere, i.e without making any change seemingly-related to django-settings, this could be a good first measure.

I too struggled a lot with phonegap steps.

The correct documentation is at the following link. http://docs.phonegap.com/en/edge/guide_cli_index.md.html

There is no more cordova command, It is replaced with phonegap.

I think that is a frequently asked question about the behavior of figures in beamer slides produced from Pandoc and markdown. The real problem is, R Markdown produces PNG images by default (from knitr), and it is hard to get the size of PNG images correct in LaTeX by default (I do not know why). It is fairly easy, however, to get the size of PDF images correct. One solution is to reset the default graphical device to PDF in your first chunk:

```{r setup, include=FALSE}
knitr::opts_chunk$set(dev = 'pdf')
```

Then all the images will be written as PDF files, and LaTeX will be happy.

Your second problem is you are mixing up the HTML units with LaTeX units in out.width / out.height. LaTeX and HTML are very different technologies. You should not expect \maxwidth to work in HTML, or 200px in LaTeX. Especially when you want to convert Markdown to LaTeX, you'd better not set out.width / out.height (use fig.width / fig.height and let LaTeX use the original size).

From what I understand, you have your data on a table and you want to create the CSV from that data. However, you have problem creating the CSV.

My thoughts would be to iterate and parse the contents of the table and generate a string from the parsed data. You can check How to convert JSON to CSV format and store in a variable for an example. You are using jQuery in your example so that would not count as an external plugin. Then, you just have to serve the resulting string using window.open and use application/octetstream as suggested.

You're declaring everything in the parent page. So the references to window and document are to the parent page's. If you want to do stuff to the iframe's, use iframe || iframe.contentWindow to access its window, and iframe.contentDocument || iframe.contentWindow.document to access its document.

There's a word for what's happening, possibly "lexical scope": What is lexical scope?

The only context of a scope is this. And in your example, the owner of the method is doc, which is the iframe's document. Other than that, anything that's accessed in this function that uses known objects are the parent's (if not declared in the function). It would be a different story if the function were declared in a different place, but it's declared in the parent page.

This is how I would write it:

(function () {
  var dom, win, doc, where, iframe;

  iframe = document.createElement('iframe');
  iframe.src = "javascript:false";

  where = document.getElementsByTagName('script')[0];
  where.parentNode.insertBefore(iframe, where);

  win = iframe.contentWindow || iframe;
  doc = iframe.contentDocument || iframe.contentWindow.document;

  doc.open();
  doc._l = (function (w, d) {
    return function () {
      w.vanishing_global = new Date().getTime();

      var js = d.createElement("script");
      js.src = 'test-vanishing-global.js?' + w.vanishing_global;

      w.name = "foobar";
      d.foobar = "foobar:" + Math.random();
      d.foobar = "barfoo:" + Math.random();
      d.body.appendChild(js);
    };
  })(win, doc);
  doc.write('<body onload="document._l();"></body>');
  doc.close();
})();

The aliasing of win and doc as w and d aren't necessary, it just might make it less confusing because of the misunderstanding of scopes. This way, they are parameters and you have to reference them to access the iframe's stuff. If you want to access the parent's, you still use window and document.

I'm not sure what the implications are of adding methods to a document (doc in this case), but it might make more sense to set the _l method on win. That way, things can be run without a prefix...such as <body onload="_l();"></body>

The question is old, but still receives a lot of attention. As the existing answers are outdated, here a more up-to-date solution:

Resizing local images

As of knitr 1.12, there is the function include_graphics. From ?include_graphics (emphasis mine):

The major advantage of using this function is that it is portable in the sense that it works for all document formats that knitr supports, so you do not need to think if you have to use, for example, LaTeX or Markdown syntax, to embed an external image. Chunk options related to graphics output that work for normal R plots also work for these images, such as out.width and out.height.

Example:

```{r, out.width = "400px"}
knitr::include_graphics("path/to/image.png")
```

Advantages:

• Over agastudy's answer: No need for external libraries or for re-rastering the image.
• Over Shruti Kapoor's answer: No need to manually write HTML. Besides, the image is included in the self-contained version of the file.

Including generated images

To compose the path to a plot that is generated in a chunk (but not included), the chunk options opts_current$get("fig.path") (path to figure directory) as well as opts_current$get("label") (label of current chunk) may be useful. The following example uses fig.path to include the second of two images which were generated (but not displayed) in the first chunk:

```{r generate_figures, fig.show = "hide"}
library(knitr)
plot(1:10, col = "green")
plot(1:10, col = "red")
```

```{r}
include_graphics(sprintf("%sgenerate_figures-2.png", opts_current$get("fig.path")))
```

The general pattern of figure paths is [fig.path]/[chunklabel]-[i].[ext], where chunklabel is the label of the chunk where the plot has been generated, i is the plot index (within this chunk) and ext is the file extension (by default png in RMarkdown documents).

First, create staticfiles folder. Inside that folder create css, js, and img folder.

main urls.py

I started to get the 500 for debug=False in the form of

django.urls.exceptions.NoReverseMatch: Reverse for 'home' not found.
or...
django.urls.exceptions.NoReverseMatch: Reverse for 'about' not found.

when raising django.core.exceptions.ValidationError instead of raising rest_framework.serializers.ValidationError

To be fair, it was already raising a 500 before, but as a ValidationError, with debug=False, this changed into the NoReverseMatch.

For me the problem was my file encoding...I used powershell to write the xml file and this was not UTF-8 ... It seems that spring requires UTF8 because as soon as I changed the encoding (using notepad++) it works again without any errors

Now i Use in my powershellscript the following line to output the xml file in UTF-8: [IO.File]::WriteAllLines($fname_dataloader_xml_config_file, $dataloader_configfile)

instead of using the redirection operator > to create my file

Note: I didn't put any xml parameters in my beans tag and it works

Follow these simple steps :

1: In the Rmarkdown script run Knit(Ctrl+Shift+K) 2: Then after the html markdown is opened click Open in Browser(top left side) and the html is opened in your web browser 3: Then use Ctrl+P and save as PDF .

I had the same problem. I solved it by removing the line break from the xml file. I did

<operationBindings>
    <OperationBinding>
        <operationType>update</operationType>
        <operationId>makePdf</operationId>
        <serverObject>
            <className>com.myclass</className>
            <lookupStyle>new</lookupStyle>
        </serverObject>
        <serverMethod>makePdf</serverMethod>
    </OperationBinding>
</operationBindings>

instead of ...

<serverObject>
            <className>com.myclass
</className>
            <lookupStyle>new</lookupStyle>
</serverObject>

Shouldn't you be providing the credentials for your site, instead of passing the DefaultCredentials?

Something like request.Credentials = new NetworkCredential("UserName", "PassWord");

Also, remove request.UseDefaultCredentials = true; request.PreAuthenticate = true;

/D tip for multiple directories: put your directory list before the search string. These all work:

findstr /D:dir1;dir2 "searchString" *.*
findstr /D:"dir1;dir2" "searchString" *.*
findstr /D:"\path\dir1\;\path\dir2\" "searchString" *.*

As expected, the path is relative to location if you don't start the directories with \. Surrounding the path with " is optional if there are no spaces in the directory names. The ending \ is optional. The output of location will include whatever path you give it. It will work with or without surrounding the directory list with ".

When you read the string from the GUI control, it is already a "raw" string. If you print out the string you might see the backslashes doubled up, but that's an artifact of how Python displays strings; internally there's still only a single backslash.

>>> a='\nu + \lambda + \theta'
>>> a
'\nu + \\lambda + \theta'
>>> len(a)
20
>>> b=r'\nu + \lambda + \theta'
>>> b
'\\nu + \\lambda + \\theta'
>>> len(b)
22
>>> b[0]
'\\'
>>> print b
\nu + \lambda + \theta

I use the following method in my project

                //kCFURLErrorDataLengthExceedsMaximum,     //-1103
            };
            int size = sizeof(codes)/sizeof(int);
            NSMutableArray *array = [[NSMutableArray alloc] init];
            for (int i=0;i<size;++i){
                [array addObject:[NSNumber numberWithInt:codes[i]]];
            }
            codesArray = [array copy];
        }
    }
    return codesArray;
}

Then I just check the error code and show alert if it is in the list

if ([[self networkErrorCodes] containsObject:[NSNumber
numberWithInt:[error code]]]){ 
// Fire Alert View Here
}

But as you can see I commented out codes that I think does not fit to my definition of NO INTERNET. E.g the code of -1012 (Authentication fail.) You may edit the list as you like.

In my project I use it at username/password entering from user. And in my view (physical) network connection errors could be the only reason to show alert view in your network based app. In any other case (e.g. incorrect username/password pair) I prefer to do some custom user friendly animation, OR just repeat the failed attempt again without any attention of the user. Especially if the user didn't explicitly initiated a network call.

Regards to martinezdelariva for a link to documentation.

List<String> arrayList = new ArrayList<String>();
for (String s : arrayList) {
    if(s.equals(value)){
        //do something
    }
}

or

for (int i = 0; i < arrayList.size(); i++) {
    if(arrayList.get(i).equals(value)){
        //do something
    }
}

But be carefull ArrayList can hold null values. So comparation should be

value.equals(arrayList.get(i))

when you are sure that value is not null or you should check if given element is null.

Try changing your Content Type (media type) to application/x-download and your Content-Disposition to: attachment;filename=" + fileName;

response.setContentType("application/x-download");
response.setHeader("Content-disposition", "attachment; filename=" + fileName);

Sometimes it's the code, not the XML

The following code,

Document doc = dBuilder.parse(new InputSource(new StringReader("file.xml")));

will also result in this error,

[Fatal Error] :1:1: Content is not allowed in prolog.org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 1; Content is not allowed in prolog.

because it's attempting to parse the string literal, "file.xml" (not the contents of the file.xml file) and failing because "file.xml" as a string is not well-formed XML.

Fix: Remove StringReader():

Document doc = dBuilder.parse(new InputSource("file.xml"));

Similarly, dirty buffer problems can leave residual junk ahead of the actual XML. If you've carefully checked your XML and are still getting this error, log the exact contents being passed to the parser; sometimes what's actually being (tried to be) parsed is surprising.

Instead of importing the logout_view function, you should provide a string in your urls.py file:

So not (r'^login/', login_view),

but (r'^login/', 'login.views.login_view'),

That is the standard way of doing things. Then you can access the URL in your templates using:

{% url login.views.login_view %}

Check the XML. It is not a valid xml.

Prolog is the first line with xml version info. It ok not to include it in your xml.

This error is thrown when the parser reads an invalid tag at the start of the document. Normally where the prolog resides.

e.g.

1. Root/><document>
2. Root<document>

it's simple, set canvas width and height to screen.width and screen.height. then press F11! think F11 should make full screen in most browsers does in FFox and IE.

Have you looked into using a HorizontalScrollView to wrap your list items? That will allow each of your list items to be horizontally scrollable (what you put in there is up to you, and can make them dynamic items similar to ListView). This will work well if you are only after a single row of items.

use this extension

extension UIImage {
    public func resize(size:CGSize, completionHandler:(resizedImage:UIImage, data:NSData?)->()) {
        dispatch_async(dispatch_get_global_queue(QOS_CLASS_USER_INITIATED, 0), { () -> Void in
            let newSize:CGSize = size
            let rect = CGRectMake(0, 0, newSize.width, newSize.height)
            UIGraphicsBeginImageContextWithOptions(newSize, false, 1.0)
            self.drawInRect(rect)
            let newImage = UIGraphicsGetImageFromCurrentImageContext()
            UIGraphicsEndImageContext()
            let imageData = UIImageJPEGRepresentation(newImage, 0.5)
            dispatch_async(dispatch_get_main_queue(), { () -> Void in
                completionHandler(resizedImage: newImage, data:imageData)
            })
        })
    }
}

If there is no internet connection in your platform and you use Eclipse, follow these steps (it solves my problem)

1. Find the exact xsd files (You can unzip these files from their jars. For example, spring-beans-x.y.xsd in spring-beans-x.y.z.RELEASE.jar)
2. Add these xsd files to Eclipse XML Catalog. (Preferences->XML->XML Catalog, Add files)
3. Add these files location to configuration file. (Be careful, write the exact version of file)

Example:

xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-x.y.xsd "

Using listAbbreviations() makes no sense as for every area it returns all the different offsets that were historically used there, not just current ones. The right base source of the list is definitely listIdentifiers().

I would generate the list just once and save it to avoid generating it for every request. I could refresh it once a month.

Also, I could put all the timezones info into a separate js-script and generate the select list itself on the client side. The js-script could be cached as well, timezones don't change often.

Also, using javascript on the client side, you can know the current local time, and hence you can find the zones that have the same time now (minutes may differ, so comparison should be approximate), and display them on the top of the list, so the user does not have to scroll through all the 400 items. You can also display adjacent zones (+/-1 hour) following.

You can view in Notepad++ no problem now (maybe older versions were bugged?)

for win64: You can find the latest plugin here: https://github.com/kapilratnani/JSON-Viewer/releases . The latest zip file contains a .dll file.

And then follow the github priject README instructions:

1. Paste the file "NPPJSONViewer.dll" to Notepad++ plugin folder
2. open a document containing a JSON string
3. Select JSON fragment and navigate to plugins/JSON Viewer/show JSON Viewer or press "Ctrl+Alt+Shift+J"
4. Voila!! if the JSON is valid, it will be shown in a Treeview

It should be the same process for win32 but I cannot personally verify it.

Make sure that the table you are returning has a schema. If not, then create a default schema (i.e. add a column in that table).

After a bit of research we came up with the following list of headers that seemed to cover most browsers:

• Expires: Sat, 26 Jul 1997 05:00:00 GMT
• Cache-Control: no-cache, private, must-revalidate, max-stale=0, post-check=0, pre-check=0 no-store
• Pragma: no-cache

In ASP.NET we added these using the following snippet:

Response.ClearHeaders(); 
Response.AppendHeader("Cache-Control", "no-cache"); //HTTP 1.1
Response.AppendHeader("Cache-Control", "private"); // HTTP 1.1
Response.AppendHeader("Cache-Control", "no-store"); // HTTP 1.1
Response.AppendHeader("Cache-Control", "must-revalidate"); // HTTP 1.1
Response.AppendHeader("Cache-Control", "max-stale=0"); // HTTP 1.1 
Response.AppendHeader("Cache-Control", "post-check=0"); // HTTP 1.1 
Response.AppendHeader("Cache-Control", "pre-check=0"); // HTTP 1.1 
Response.AppendHeader("Pragma", "no-cache"); // HTTP 1.0 
Response.AppendHeader("Expires", "Sat, 26 Jul 1997 05:00:00 GMT"); // HTTP 1.0

Use the time.Now() function and the time.Format() method.

t := time.Now()
fmt.Println(t.Format("20060102150405"))

prints out 20110504111515, or at least it did a few minutes ago. (I'm on Eastern Daylight Time.) There are several pre-defined time formats in the constants defined in the time package.

You can use time.Now().UTC() if you'd rather have UTC than your local time zone.

JAVACMD is an Ant specific environment variable. Ant doc says:

JAVACMD—full path of the Java executable. Use this to invoke a different JVM than JAVA_HOME/bin/java(.exe).

So, if your java.exe full path is: C:\Program Files\Java\jdk1.8.0_211\bin\java.exe, create a new environment variable called JAVACMD and set its value to the mentioned path (including \java.exe). Note that you need to close and reopen your terminal (cmd, Powershell, etc) so the new environment variable takes effect.

As rcar says, you can't without losing some quality, the best you can do in c# is:

Bitmap newImage = new Bitmap(newWidth, newHeight);
using (Graphics gr = Graphics.FromImage(newImage))
{
    gr.SmoothingMode = SmoothingMode.HighQuality;
    gr.InterpolationMode = InterpolationMode.HighQualityBicubic;
    gr.PixelOffsetMode = PixelOffsetMode.HighQuality;
    gr.DrawImage(srcImage, new Rectangle(0, 0, newWidth, newHeight));
}

Here is what I ended up doing to work around the error.

First, I set up the database recovery model as SIMPLE. More information here.

Then, by deleting some old files I was able to make 5GB of free space which gave the log file more space to grow.

I reran the DELETE statement sucessfully without any warning.

I thought that by running the DELETE statement the database would inmediately become smaller thus freeing space in my hard drive. But that was not true. The space freed after a DELETE statement is not returned to the operating system inmediatedly unless you run the following command:

DBCC SHRINKDATABASE (MyDb, 0);
GO

More information about that command here.

A quick googling on "perl high resolution timers" gave a reference to Time::HiRes. Maybe that it what you want.

Here's the raw reference of PDF 1.7, and here's an article describing the structure of a PDF file. If you use Vim, the pdftk plugin is a good way to explore the document in an ever-so-slightly less raw form, and the pdftk utility itself (and its GPL source) is a great way to tease documents apart.

I have found a way to resize the buffer size without influencing the window size. It works thanks to a flaw in how batch works but it gets the job done.

mode 648 78 >nul 2>nul

How does it work? There is a syntax error in this command, it should be "mode 648, 78". Because of how batch works, the buffer size will first be resized to 648 and then the window resize will come but it will never finish, because of the syntax error. Voila, buffer size is adjusted and the window size stays the same. This produces an ugly error so to get rid of it just add the ">nul 2>nul" and you're done.

In my case, I changed the android section in build.gradle and the problem faded away:

android {
compileSdkVersion 28

lintOptions {
    disable 'InvalidPackage'
}

defaultConfig {
    // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
    applicationId "app.ozel"
    minSdkVersion 16
    targetSdkVersion 28
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}

buildTypes {
    release {
        // TODO: Add your own signing config for the release build.
        // Signing with the debug keys for now, so `flutter run --release` works.
        signingConfig signingConfigs.debug
    }
}

}

this should work

the question is why would you want to do that...you may want to rethink the data model. you can replace null with whatever you want.

I created a custom class MyButton extended from UIButton. Then added this inside the Identity Inspector:

After this, change the button type to Custom:

Then you can set attributes like textColor and UIFont for your UIButton for the different states:

Then I also created two methods inside MyButton class which I have to call inside my code when I want a UIButton to be displayed as highlighted:

- (void)changeColorAsUnselection{
    [self setTitleColor:[UIColor colorFromHexString:acColorGreyDark] 
               forState:UIControlStateNormal & 
                        UIControlStateSelected & 
                        UIControlStateHighlighted];
}

- (void)changeColorAsSelection{
    [self setTitleColor:[UIColor colorFromHexString:acColorYellow] 
               forState:UIControlStateNormal & 
                        UIControlStateHighlighted & 
                        UIControlStateSelected];
}

You have to set the titleColor for normal, highlight and selected UIControlState because there can be more than one state at a time according to the documentation of UIControlState. If you don't create these methods, the UIButton will display selection or highlighting but they won't stay in the UIColor you setup inside the UIInterface Builder because they are just available for a short display of a selection, not for displaying selection itself.

This example will help you to understand the React Life Cycle Hooks.

You can setState in getDerivedStateFromProps method i.e. static and trigger the method after props change in componentDidUpdate.

In componentDidUpdate you will get 3rd param which returns from getSnapshotBeforeUpdate.

The for each syntax is supported as an extension to native c++ in Visual Studio.

The example provided in msdn

#include <vector>
#include <iostream>

using namespace std;

int main() 
{
  int total = 0;

  vector<int> v(6);
  v[0] = 10; v[1] = 20; v[2] = 30;
  v[3] = 40; v[4] = 50; v[5] = 60;

  for each(int i in v) {
    total += i;
  }

  cout << total << endl;
}

(works in VS2013) is not portable/cross platform but gives you an idea of how to use for each.

The standard alternatives (provided in the rest of the answers) apply everywhere. And it would be best to use those.

System.out.println("I\nam\na\nboy");

System.out.println("I am a boy".replaceAll("\\s+","\n"));

System.out.println("I am a boy".replaceAll("\\s+",System.getProperty("line.separator"))); // portable way

If this SQL is being used in any peoplesoft specific code (Application Engine, SQLEXEC, SQLfetch, etc..) you could use %Datein metaSQL. Peopletools automatically converts the date to a format which would be accepted by the database platform the application is running on.

In case this SQL is being used to perform a backend update from a query analyzer (like SQLDeveloper, SQLTools), the date format that is being used is wrong. Oracle expects the date format to be DD-MMM-YYYY, where MMM could be JAN, FEB, MAR, etc..

.toString() is available, or just add "" to the end of the int

var x = 3,
    toString = x.toString(),
    toConcat = x + "";

Angular is simply JavaScript at the core.

The best way is:

  $ docker cp CONTAINER:FILEPATH LOCALFILEPATH
  $ vi LOCALFILEPATH
  $ docker cp LOCALFILEPATH CONTAINER:FILEPATH

Limitations with $ docker exec: it can only attach to a running container.

Limitations with $ docker run: it will create a new container.

It sounds like you want an image button:

<input type="image" src="logg.png" name="saveForm" class="btTxt submit" id="saveForm" />

Alternatively, you can use CSS to make the existing submit button use your image as its background.

In any case, you don't want a separate <img /> element on the page.

The second (assuming you means CONTAINS, and actually put it in a valid query) should be faster, because it can use some form of index (in this case, a full text index). Of course, this form of query is only available if the column is in a full text index. If it isn't, then only the first form is available.

The first query, using LIKE, will be unable to use an index, since it starts with a wildcard, so will always require a full table scan.

The CONTAINS query should be:

SELECT * FROM table WHERE CONTAINS(Column, 'test');

Cross-site cookies are allowed if:

1. the Set-Cookie response header includes SameSite=None; Secure as seen here and here
2. and your browser hasn't disabled 3rd-party cookies.*

Let's clarify a "domain" vs a "site"; I always find a quick reminder of "anatomy of a URL" helps me. In this URL https://example.com:8888/examples/index.html, remember these main parts (got from this paper):

• the "protocol": https://
• the "hostname/host": example.com
• the "port": 8888
• the "path":/examples/index.html.

Notice the difference between "path" and "site" for Cookie purposes. "path" is not security-related; "site" is security-related:

path

Servers can set a Path attribute in the Set-Cookie, but it doesn't seem security related:

Note that path was intended for performance, not security. Web pages having the same origin still can access cookie via document.cookie even though the paths are mismatched.

site

The SameSite attribute, according to web.dev article, can restrict or allow cross-site cookies; but what is a "site"?

It's helpful to understand exactly what 'site' means here. The site is the combination of the domain suffix and the part of the domain just before it. For example, the www.web.dev domain is part of the web.dev site.

This means what's to the left of web.dev is a subdomain; yep, www is the subdomain (but the subdomain is a part of the host; see the BONUS reply in this answer)

In this URL https://www.example.com:8888/examples/index.html, remember these parts:

• the "protocol": https://
• the "hostname" aka "host": example.com
• (in cases like "en.wikipedia.org", the entire "en.example.com" is also a hostname)
• the "port": 8888
• the "site": www.example.com
• the "domain": example.com
• the "subdomain": www
• the "path": /examples/index.html

(Be careful; I was testing my feature in Chrome Incognito tab; according to my chrome://settings/cookies; my settings were "Block third party cookies in Incognito", so I can't test Cross-site cookies in Incognito.)

Since we are talking about having every element exactly once, a "set" makes more sense to me.

Example with classes and IEqualityComparer implemented:

 public class Product
    {
        public int Id { get; set; }
        public string Name { get; set; }

        public Product(int x, string y)
        {
            Id = x;
            Name = y;
        }
    }

    public class ProductCompare : IEqualityComparer<Product>
    {
        public bool Equals(Product x, Product y)
        {  //Check whether the compared objects reference the same data.
            if (Object.ReferenceEquals(x, y)) return true;

            //Check whether any of the compared objects is null.
            if (Object.ReferenceEquals(x, null) || Object.ReferenceEquals(y, null))
                return false;

            //Check whether the products' properties are equal.
            return x.Id == y.Id && x.Name == y.Name;
        }
        public int GetHashCode(Product product)
        {
            //Check whether the object is null
            if (Object.ReferenceEquals(product, null)) return 0;

            //Get hash code for the Name field if it is not null.
            int hashProductName = product.Name == null ? 0 : product.Name.GetHashCode();

            //Get hash code for the Code field.
            int hashProductCode = product.Id.GetHashCode();

            //Calculate the hash code for the product.
            return hashProductName ^ hashProductCode;
        }
    }

Now

List<Product> originalList = new List<Product> {new Product(1, "ad"), new Product(1, "ad")};
var setList = new HashSet<Product>(originalList, new ProductCompare()).ToList();

setList will have unique elements

I thought of this while dealing with .Except() which returns a set-difference

1 and 2 are SAML 1.1 because those URIs were part of the OASIS SAML 1.1 standard. Section 8.3 of the linked PDF for the OASIS SAML 2.0 standard explains this:

Where possible an existing URN is used to specify a protocol. In the case of IETF protocols, the URN of the most current RFC that specifies the protocol is used. URI references created specifically for SAML have one of the following stems, according to the specification set version in which they were first introduced:

One way to solve this error is to put the ForeignKey attribute on top of the property you want as a foreign key and add the navigation property.

Note: In the ForeignKey attribute, between parentheses and double quotes, place the name of the class referred to in this way.

Assuming you want to access folder named xzy two folders up your python file. This works for me and platform independent.

".././xyz"

There is no runtime performance cost to using var. Though, I would suspect there to be a compiling performance cost as the compiler needs to infer the type, though this will most likely be negligable.

Here is some documentation that helps.

sys.dm_tran_locks contains the locking information of the sessions

If you want to know a specific table is locked or not, you can use the following query

SELECT 
 * 
from 
 sys.dm_tran_locks 
where 
  resource_associated_entity_id = object_id('schemaname.tablename')

if you are interested in finding both login name of the user and the query being run

SELECT
 DB_NAME(resource_database_id)
 , s.original_login_name
 , s.status
 , s.program_name
 , s.host_name
 , (select text from sys.dm_exec_sql_text(exrequests.sql_handle))
 ,*
from
  sys.dm_tran_locks dbl
     JOIN sys.dm_exec_sessions s ON dbl.request_session_id = s.session_id
  INNER JOIN  sys.dm_exec_requests exrequests on dbl.request_session_id = exrequests.session_id
where
 DB_NAME(dbl.resource_database_id) = 'dbname'

This answer should work for Windows users that have had trouble getting this working with Visual Studio with any of the other answers.

1. Download the dirent.h file from the github page. But is better to just use the Raw dirent.h file and follow my steps below (it is how I got it to work).

   Github page for dirent.h for Windows: Github page for dirent.h

   Raw Dirent File: Raw dirent.h File

2. Go to your project and Add a new Item (Ctrl+Shift+A). Add a header file (.h) and name it dirent.h.

3. Paste the Raw dirent.h File code into your header.

4. Include "dirent.h" in your code.

5. Put the below void filefinder() method in your code and call it from your main function or edit the function how you want to use it.

   #include <stdio.h>
   #include <string.h>
   #include "dirent.h"
   
   string path = "C:/folder"; //Put a valid path here for folder
   
   void filefinder()
   {
       DIR *directory = opendir(path.c_str());
       struct dirent *direntStruct;
   
       if (directory != NULL) {
           while (direntStruct = readdir(directory)) {
               printf("File Name: %s\n", direntStruct->d_name); //If you are using <stdio.h>
               //std::cout << direntStruct->d_name << std::endl; //If you are using <iostream>
           }
       }
       closedir(directory);
   }

I have a files only website. Added MVC 5 to webforms application (targeting net45). I had to modify the packages.config

package id="Microsoft.AspNet.Mvc" version="5.2.3" targetFramework="net45"

to

package id="Microsoft.AspNet.Mvc" version="5.2.3" targetFramework="net45" developmentDependency="true"

in order for it to startup on local box in debug mode (previously had the top described error). Running VS 2017 on Windows 7...opened through File > Open > Web Site > File (chose root directory outside of IIS).

The solution seems to be to add multiple @font-face rules, for example:

@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans.ttf");
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-Bold.ttf");
    font-weight: bold;
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-Oblique.ttf");
    font-style: italic, oblique;
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-BoldOblique.ttf");
    font-weight: bold;
    font-style: italic, oblique;
}

By the way, it would seem Google Chrome doesn't know about the format("ttf") argument, so you might want to skip that.

(This answer was correct for the CSS 2 specification. CSS3 only allows for one font-style rather than a comma-separated list.)

I find Core Graphics to be pretty simple for Swift 3:

if let cgcontext = UIGraphicsGetCurrentContext() {
    cgcontext.strokeEllipse(in: CGRect(x: center.x-diameter/2, y: center.y-diameter/2, width: diameter, height: diameter))
}

If your IDE is in power save mode, then the run button etc. are also disabled.

You can verify this via the file -> power save mode, make sure it is disabled.

I think you need to use for example:

aws ecs list-container-instances --cluster default --region us-east-1

This depends of your region of course.

No you don't need to check if you're in the main thread. Here is how you can do this in Swift:

runThisInMainThread { () -> Void in
    runThisInMainThread { () -> Void in
        // No problem
    }
}

func runThisInMainThread(block: dispatch_block_t) {
    dispatch_async(dispatch_get_main_queue(), block)
}

Its included as a standard function in my repo, check it out: https://github.com/goktugyil/EZSwiftExtensions

Here all solutions are based on Class Component, but i guess most of the people who learned React recently (like me), at this time using functional Component. So here is the solution based on functional component.

Using useRef hooks of ReactJs and inputRef property of TextField.

    import React, { useRef, Component } from 'react'
    import { TextField, Button } from '@material-ui/core'
    import SendIcon from '@material-ui/icons/Send'

    export default function MultilineTextFields() {
    const valueRef = useRef('') //creating a refernce for TextField Component

    const sendValue = () => {
        return console.log(valueRef.current.value) //on clicking button accesing current value of TextField and outputing it to console 
    }

    return (
        <form noValidate autoComplete='off'>
        <div>
            <TextField
            id='outlined-textarea'
            label='Content'
            placeholder='Write your thoughts'
            multiline
            variant='outlined'
            rows={20}
            inputRef={valueRef}   //connecting inputRef property of TextField to the valueRef
            />
            <Button
            variant='contained'
            color='primary'
            size='small'
            endIcon={<SendIcon />}
            onClick={sendValue}
            >
            Send
            </Button>
        </div>
        </form>
    )
    }

As mentioned above @NotNull does nothing on its own. A good way of using @NotNull would be using it with Objects.requireNonNull

public class Foo {
    private final Bar bar;

    public Foo(@NotNull Bar bar) {
        this.bar = Objects.requireNonNull(bar, "bar must not be null");
    }
}

I was able to resolve this issue (as others mentioned in comments) by disabling "Enable Promotion of Distributed Transactions for RPC" (i.e. setting it to False):

As requested by @WonderWorker, you can do this via SQL script:

EXEC master.dbo.sp_serveroption
     @server = N'[mylinkedserver]',
     @optname = N'remote proc transaction promotion',
     @optvalue = N'false'

Answer is as follows:

super.Mymethod();
super();                // calls base class Superclass constructor.
super(parameter list);          // calls base class parameterized constructor.
super.method();         // calls base class method.

it's the same as think the next:

"starting with i = 0, while i is less than 8, and adding one to i at the end of the parenthesis, do the instructions between brackets"

It's also the same as:

while( i < 8 )
{
    // instrucctions like:
    Console.WriteLine(i);
    i++;
}

the For sentences is a basis of coding, and it's as useful as necessary its understanding.

It's the way to repeat n-times the same instrucction, or browse ( or do something with each element) an array

Simply use :

mapA.equals(mapB);

Compares the specified object with this map for equality. Returns true if the given object is also a map and the two maps represent the same mappings

Replacing image: ${DOCKER_REGISTRY}notificationsapi with image:notificationsapi or image: ${docker_registry}notificationsapi in docker-compose.yml did solves the issue

file with error

  version: '3.4'

services:
  notifications.api:
    image: ${DOCKER_REGISTRY}notificationsapi
    build:
      context: .
      dockerfile: ../Notifications.Api/Dockerfile

file without error

version: '3.4'

services:
 notifications.api:
    image: ${docker_registry}notificationsapi
    build:
      context: .
      dockerfile: ../Notifications.Api/Dockerfile

So i think error was due to non lower case letters it had

CREATE PROCEDURE [dbo].[sp_Myforeach_Date]
    -- Add the parameters for the stored procedure here
    @SatrtDate as DateTime,
    @EndDate as dateTime,
    @DatePart as varchar(2),
    @OutPutFormat as int 
AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    Declare @DateList Table
    (Date varchar(50))

    WHILE @SatrtDate<= @EndDate
    BEGIN
    INSERT @DateList (Date) values(Convert(varchar,@SatrtDate,@OutPutFormat))
    IF Upper(@DatePart)='DD'
    SET @SatrtDate= DateAdd(dd,1,@SatrtDate)
    IF Upper(@DatePart)='MM'
    SET @SatrtDate= DateAdd(mm,1,@SatrtDate)
    IF Upper(@DatePart)='YY'
    SET @SatrtDate= DateAdd(yy,1,@SatrtDate)
    END 
    SELECT * FROM @DateList
END

Just put this Code and call the SP in This way

exec sp_Myforeach_Date @SatrtDate='03 Jan 2010',@EndDate='03 Mar 2010',@DatePart='dd',@OutPutFormat=106

I also had the same issue. Tried all ways and it didn't work out until I added the following in app.module.ts

import { Ng4LoadingSpinnerModule } from 'ng4-loading-spinner';

And add the following in your imports in app.module.ts

Ng4LoadingSpinnerModule.forRoot()

This case might be rare but I hope this helps someone out there

Try =Year(Now()) and format the cell as General.

The best option is create a directive and wrap the slider features there. The secret is use $timeout, the jquery code will be called only when DOM is ready.

angular.module('app')
.directive('my-slider', 
    ['$timeout', function($timeout) {
        return {
            restrict:'E',
            scope: true,
            template: '<div id="{{ id }}"></div>',
            link: function($scope) {
                $scope.id = String(Math.random()).substr(2, 8);

                $timeout(function() {
                    angular.element('#'+$scope.id).slider();                    
                });
            }
        };
    }]
);

What's wrong with

var arr2 = new Array(10,20);
    arr2[0,0] = 5;
    arr2[0,1] = 2
    console.log("sum is   " + (arr2[0,0] +  arr2[0,1]))

should read out "sum is 7"

Float elements will be rendered at the line they are normally in the layout. To fix this, you have two choices:

Move the header and the p after the login box:

<div class='container'>
    <div class='hero-unit'>

        <div id='login-box' class='pull-right control-group'>
            <div class='clearfix'>
                <input type='text' placeholder='Username' />
            </div>
            <div class='clearfix'>
                <input type='password' placeholder='Password' />
            </div>
            <button type='button' class='btn btn-primary'>Log in</button>
        </div>

        <h2>Welcome</h2>

        <p>Please log in</p>

    </div>
</div>

Or enclose the left block in a pull-left div, and add a clearfix at the bottom

<div class='container'>
    <div class='hero-unit'>

        <div class="pull-left">

          <h2>Welcome</h2>

          <p>Please log in</p>

        </div>

        <div id='login-box' class='pull-right control-group'>
            <div class='clearfix'>
                <input type='text' placeholder='Username' />
            </div>
            <div class='clearfix'>
                <input type='password' placeholder='Password' />
            </div>
            <button type='button' class='btn btn-primary'>Log in</button>
        </div>

        <div class="clearfix"></div>

    </div>
</div>

This parameter is is working for me:

--enable-easy-off-store-extension-install

Do the following:

1. Right click on your "Chrome" icon.
2. Choose properties
3. At the end of your target line, place these parameters: --enable-easy-off-store-extension-install
4. It should look like: chrome.exe --enable-easy-off-store-extension-install
5. Start Chrome by double-clicking on the icon

when use header.php for every page for the navbar code, the jquery does not work, the active is applied and then removed, a simple solution, is as follows

on every page set variable <?php $pageName = "index"; ?> on Index page and similarly <?php $pageName = "contact"; ?> on Contact us page

then call the header.php (ie the nav code is in header.php) <?php include('header.php'); >

in the header.php ensure that each nav-link is as follows

<a class="nav-link <?php if ($page_name == 'index') {echo "active";} ?> href="index.php">Home</a>

<a class="nav-link <?php if ($page_name == 'contact') {echo "active";} ?> href="contact.php">Contact Us</a>

hope this helps cause i have spent days to get the jquery to work but failed,

if someone would kindly explain what exactly is the issue when the header.php is included and then page loads... why the jquery fails to add the active class to the nav-link..??

Here is one line command to get the volume information for running containers:

for contId in `docker ps -q`; do echo "Container Name: "   `docker ps -f "id=$contId" | awk '{print $NF}' | grep -v NAMES`; echo "Container Volume: " `docker inspect -f '{{.Config.Volumes}}' $contId`; docker inspect -f '{{ json .Mounts }}' $contId  | jq '.[]';   printf "\n"; done

Output is:

I have noticed that when intellisence doesn't work for an object there is usually an error somewhere in the class above line you are working on.

The other option is that you didn't instantiated the FileUpload object as an instance variable. make sure the code:

FileUpload fileUpload = new FileUpload();

is not inside a function in your code behind.

I use the following .gitignore for C# projects. Additional patterns are added as and when they are needed.

[Oo]bj
[Bb]in
*.user
*.suo
*.[Cc]ache
*.bak
*.ncb
*.log 
*.DS_Store
[Tt]humbs.db 
_ReSharper.*

Ankh.NoLoad

file_get_contents('php://input') will not always work.

I have a request with in the headers "content-length=735" and "php://input" is empty string. So depends on how good/valid the HTTP request is.

If you are using hash or browser history then you can do

hashHistory.push('/login');
browserHistory.push('/login');

I've encountered this error too.

My problem was that I've changed a method's signature, something like

void invest(Currency money){...}

into

void invest(Euro money){...}

This method was invoked from a context similar to

public static void main(String args[]) {
    Bank myBank = new Bank();

    Euro capital = new Euro();
    myBank.invest(capital);
}

The compiler was silent with regard to warnings/ errors, as capital is both Currency as well as Euro.

The problem appeared due to the fact that I only compiled the class in which the method was defined - Bank, but not the class from which the method is being called from, which contains the main() method.

This issue is not something you might encounter too often, as most frequently the project is rebuilt mannually or a Build action is triggered automatically, instead of just compiling the one modified class.

My usecase was that I generated a .jar file which was to be used as a hotfix, that did not contain the App.class as this was not modified. It made sense to me not to include it as I kept the initial argument's base class trough inheritance.

The thing is, when you compile a class, the resulting bytecode is kind of static, in other words, it's a hard-reference.

The original disassembled bytecode (generated with the javap tool) looks like this:

 #7 = Methodref          #2.#22         // Bank.invest:(LCurrency;)V

After the ClassLoader loads the new compiled Bank.class, it will not find such a method, it appears as if it was removed and not changed, thus the named error.

Hope this helps.

You can use:

if ($(selector).is('*')) {
  // Do something
}

A little more elegant, perhaps.

This happens when the pointer passed to free() is not valid or has been modified somehow. I don't really know the details here. The bottom line is that the pointer passed to free() must be the same as returned by malloc(), realloc() and their friends. It's not always easy to spot what the problem is for a novice in their own code or even deeper in a library. In my case, it was a simple case of an undefined (uninitialized) pointer related to branching.

The free() function frees the memory space pointed to by ptr, which must have been returned by a previous call to malloc(), calloc() or realloc(). Otherwise, or if free(ptr) has already been called before, undefined behavior occurs. If ptr is NULL, no operation is performed. GNU 2012-05-10 MALLOC(3)

char *words; // setting this to NULL would have prevented the issue

if (condition) {
    words = malloc( 512 );

    /* calling free sometime later works here */

    free(words)
} else {

    /* do not allocate words in this branch */
}

/* free(words);  -- error here --
*** glibc detected *** ./bin: munmap_chunk(): invalid pointer: 0xb________ ***/

There are many similar questions here about the related free() and rellocate() functions. Some notable answers providing more details:

*** glibc detected *** free(): invalid next size (normal): 0x0a03c978 ***
*** glibc detected *** sendip: free(): invalid next size (normal): 0x09da25e8 ***
glibc detected, realloc(): invalid pointer

IMHO running everything in a debugger (Valgrind) is not the best option because errors like this are often caused by inept or novice programmers. It's more productive to figure out the issue manually and learn how to avoid it in the future.

I'm not an expert in JQuery but I have the same scenario and I able to accomplis like this:

$("#data tr").click(function(){
   $(this).addClass("selected").siblings().removeClass("selected"); 
});

Style:

<style type="text/css">

.selected {
    background: red;
}

</style> 

As specified here You can update the index:

git update-index --assume-unchanged /path/to/file

By doing this, the files will not show up in git status or git diff.

To begin tracking the files again you can run:

git update-index --no-assume-unchanged /path/to/file

The problem is you haven't declared your interface state replace any with your suitable variable type of the 'value'

Here is a good reference

interface AppProps {
   //code related to your props goes here
}

interface AppState {
   value: any
}

class App extends React.Component<AppProps, AppState> {
  // ...
}

If you are producing the DataTable from an SQL query, have you considered simply using Dapper instead?

Then, instead of making a SqlCommand with SqlParameters and a DataTable and a DataAdapter and on and on, which you then have to laboriously convert to a class, you just define the class, make the query column names match the field names, and the parameters are bound easily by name. You already have the TankReading class defined, so it will be really simple!

using Dapper;

// Below can be SqlConnection cast to DatabaseConnection, too.
DatabaseConnection connection = // whatever
IEnumerable<TankReading> tankReadings = connection.Query<TankReading>(
   "SELECT * from TankReading WHERE Value = @value",
   new { value = "tank1" } // note how `value` maps to `@value`
);
return tankReadings;

Now isn't that awesome? Dapper is very optimized and will give you darn near equivalent performance as reading directly with a DataAdapter.

If your class has any logic in it at all or is immutable or has no parameterless constructor, then you probably do need to have a DbTankReading class (as a pure POCO/Plain Old Class Object):

// internal because it should only be used in the data source project and not elsewhere
internal sealed class DbTankReading {
   int TankReadingsID { get; set; }
   DateTime? ReadingDateTime { get; set; }
   int ReadingFeet { get; set; }
   int ReadingInches { get; set; }
   string MaterialNumber { get; set; }
   string EnteredBy { get; set; }
   decimal ReadingPounds { get; set; }
   int MaterialID { get; set; }
   bool Submitted { get; set; }
}

You'd use that like this:

IEnumerable<TankReading> tankReadings = connection
   .Query<DbTankReading>(
      "SELECT * from TankReading WHERE Value = @value",
      new { value = "tank1" } // note how `value` maps to `@value`
   )
   .Select(tr => new TankReading(
      tr.TankReadingsID,
      tr.ReadingDateTime,
      tr.ReadingFeet,
      tr.ReadingInches,
      tr.MaterialNumber,
      tr.EnteredBy,
      tr.ReadingPounds,
      tr.MaterialID,
      tr.Submitted
   });

Despite the mapping work, this is still less painful than the data table method. This also lets you perform some kind of logic, though if the logic is any more than very simple straight-across mapping, I'd put the logic into a separate TankReadingMapper class.

cursor.execute("INSERT INTO table VALUES (%s, %s, %s)", (var1, var2, var3))

Note that the parameters are passed as a tuple.

The database API does proper escaping and quoting of variables. Be careful not to use the string formatting operator (%), because

1. it does not do any escaping or quoting.
2. it is prone to Uncontrolled string format attacks e.g. SQL injection.

I use GateOne from the synocommunity.

Go into settings in Package Center and add http://packages.synocommunity.com/ as a package source. Then you should be able to add it easily via Package Center.

While I agree with everyone else, if you are dead set on using frames anyway, you can just do index.html in XHTML and then do the contents of the frames in HTML5.

With Enzyme 3, if you need to change an input value but don't need to fire the onChange function you can just do this (node property has been removed):

wrapper.find('input').instance().value = "foo";

You can use wrapper.find('input').simulate("change", { target: { value: "foo" }}) to invoke onChange if you have a prop for that (ie, for controlled components).

You partial looks much like an editor template so you could include it as such (assuming of course that your partial is placed in the ~/views/controllername/EditorTemplates subfolder):

@Html.EditorFor(model => model.SomePropertyOfTypeLocaleBaseModel)

Or if this is not the case simply:

@Html.Partial("nameOfPartial", Model)

The pop method of dicts (like self.data, i.e. {'a':'aaa','b':'bbb','c':'ccc'}, here) takes two arguments -- see the docs

The second argument, default, is what pop returns if the first argument, key, is absent. (If you call pop with just one argument, key, it raises an exception if that key's absent).

In your example, print b.pop('a',{'b':'bbb'}), this is irrelevant because 'a' is a key in b.data. But if you repeat that line...:

b=a()
print b.pop('a',{'b':'bbb'})
print b.pop('a',{'b':'bbb'})
print b.data

you'll see it makes a difference: the first pop removes the 'a' key, so in the second pop the default argument is actually returned (since 'a' is now absent from b.data).

You're trying to use a dict as a key to another dict or in a set. That does not work because the keys have to be hashable. As a general rule, only immutable objects (strings, integers, floats, frozensets, tuples of immutables) are hashable (though exceptions are possible). So this does not work:

>>> dict_key = {"a": "b"}
>>> some_dict[dict_key] = True
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'dict'

To use a dict as a key you need to turn it into something that may be hashed first. If the dict you wish to use as key consists of only immutable values, you can create a hashable representation of it like this:

>>> key = frozenset(dict_key.items())

Now you may use key as a key in a dict or set:

>>> some_dict[key] = True
>>> some_dict
{frozenset([('a', 'b')]): True}

Of course you need to repeat the exercise whenever you want to look up something using a dict:

>>> some_dict[dict_key]                     # Doesn't work
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'dict'
>>> some_dict[frozenset(dict_key.items())]  # Works
True

If the dict you wish to use as key has values that are themselves dicts and/or lists, you need to recursively "freeze" the prospective key. Here's a starting point:

def freeze(d):
    if isinstance(d, dict):
        return frozenset((key, freeze(value)) for key, value in d.items())
    elif isinstance(d, list):
        return tuple(freeze(value) for value in d)
    return d

If you want the result plus the number of rows returned do something like this. Using PHP.

$query = "SELECT * FROM Employee";
$result = mysql_query($query);
echo "There are ".mysql_num_rows($result)." Employee(s).";

querySelector is of w3c Selector API

getElementBy is of w3c DOM API

IMO the most notable difference is that the return type of querySelectorAll is a static node list and for getElementsBy it's a live node list. Therefore the looping in demo 2 never ends because lis is live and updates itself during each iteration.

// Demo 1 correct
var ul = document.querySelectorAll('ul')[0],
    lis = ul.querySelectorAll("li");
for(var i = 0; i < lis.length ; i++){
    ul.appendChild(document.createElement("li"));
}

// Demo 2 wrong
var ul = document.getElementsByTagName('ul')[0], 
    lis = ul.getElementsByTagName("li"); 
for(var i = 0; i < lis.length ; i++){
    ul.appendChild(document.createElement("li")); 
}

The default value of end is \n meaning that after the print statement it will print a new line. So simply stated end is what you want to be printed after the print statement has been executed

Eg: - print ("hello",end=" +") will print hello +

I work in PHP and use a function to decode the binary data sent back from the server. I extract the information an input to a simple file.php and view the file through my server and all browser display the pdf artefact.

<?php
   $data = 'dfjhdfjhdfjhdfjhjhdfjhdfjhdfjhdfdfjhdf==blah...blah...blah..'

   $data = base64_decode($data);
    header("Content-type: application/pdf");
    header("Content-Length:" . strlen($data ));
    header("Content-Disposition: inline; filename=label.pdf");
    print $data;
    exit(1);

?>

Just use the plain ol' class selector.

$('#my_id .my_class')

It doesn't matter if the element also has other classes. It has the .my_class class, and it's somewhere inside #my_id, so it will match that selector.

Regarding performance

According to the jQuery selector performance documentation, it's faster to use the two selectors separately, like this:

$('#my_id').find('.my_class')

Here's the relevant part of the documentation:

ID-Based Selectors

// Fast:
$( "#container div.robotarm" );

// Super-fast:
$( "#container" ).find( "div.robotarm" );

The .find() approach is faster because the first selection is handled without going through the Sizzle selector engine – ID-only selections are handled using document.getElementById(), which is extremely fast because it is native to the browser.

Selecting by ID or by class alone (among other things) invokes browser-supplied functions like document.getElementById() which are quite rapid, whereas using a descendent selector invokes the Sizzle engine as mentioned which, although fast, is slower than the suggested alternative.

Sometimes you want to store data, like global variables which need to be accessed from multiple Activities - sometimes everywhere within the application. In this case, the Application object will help you.

For example, if you want to get the basic authentication data for each http request, you can implement the methods for authentication data in the application object.

After this,you can get the username and password in any of the activities like this:

MyApplication mApplication = (MyApplication)getApplicationContext();
String username = mApplication.getUsername();
String password = mApplication.getPassword();

And finally, do remember to use the Application object as a singleton object:

 public class MyApplication extends Application {
    private static MyApplication singleton;

    public MyApplication getInstance(){
        return singleton;
    }
    @Override
    public void onCreate() {
        super.onCreate();
        singleton = this;
    }
}

You should do the following on the CLI : 1. aws configure'
2. input the access key 3. input secret key 4. and then the region i.e : eu-west-1 (leave the a or b after the 1)

I used GENEGC's script, but I found it quite slow.

It is slow because it scans whole sheet on every edit.

So I wrote way faster and cleaner method for myself and I wanted to share it.

function onEdit(e) {
    if (e) { 
        var ss = e.source.getActiveSheet();
        var r = e.source.getActiveRange(); 

        // If you want to be specific
        // do not work in first row
        // do not work in other sheets except "MySheet"
        if (r.getRow() != 1 && ss.getName() == "MySheet") {

            // E.g. status column is 2nd (B)
            status = ss.getRange(r.getRow(), 2).getValue();

            // Specify the range with which You want to highlight
            // with some reading of API you can easily modify the range selection properties
            // (e.g. to automatically select all columns)
            rowRange = ss.getRange(r.getRow(),1,1,19);

            // This changes font color
            if (status == 'YES') {
                rowRange.setFontColor("#999999");
            } else if (status == 'N/A') {
                rowRange.setFontColor("#999999");
            // DEFAULT
            } else if (status == '') { 
                rowRange.setFontColor("#000000");
            }   
        }
    }
}

Use kafka-consumer-groups.sh

For example

bin/kafka-consumer-groups.sh  --list --bootstrap-server localhost:9092

bin/kafka-consumer-groups.sh --describe --group mygroup --bootstrap-server localhost:9092

When there is data already in HDFS, an external Hive table can be created to describe the data. It is called EXTERNAL because the data in the external table is specified in the LOCATION properties instead of the default warehouse directory.

When keeping data in the internal tables, Hive fully manages the life cycle of the table and data. This means the data is removed once the internal table is dropped. If the external table is dropped, the table metadata is deleted but the data is kept. Most of the time, an external table is preferred to avoid deleting data along with tables by mistake.

Some compilers support compound literals as an extention, allowing this construct:

Customer customerRecords[2];
customerRecords[0] = (Customer){25, "Bob Jones"};
customerRecords[1] = (Customer){26, "Jim Smith"};

But it's rather unportable.

When you return cell's contentView you will have a 2 problems:

1. crash related to gestures
2. you don't reusing contentView (every time on viewForHeaderInSection call, you creating new cell)

Solution:

Wrapper class for table header\footer. It is just container, inherited from UITableViewHeaderFooterView, which holds cell inside

https://github.com/Magnat12/MGTableViewHeaderWrapperView.git

Register class in your UITableView (for example, in viewDidLoad)

- (void)viewDidLoad {
    [super viewDidLoad];
    [self.tableView registerClass:[MGTableViewHeaderWrapperView class] forHeaderFooterViewReuseIdentifier:@"ProfileEditSectionHeader"];
}

In your UITableViewDelegate:

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
    MGTableViewHeaderWrapperView *view = [tableView dequeueReusableHeaderFooterViewWithIdentifier:@"ProfileEditSectionHeader"];

    // init your custom cell
    ProfileEditSectionTitleTableCell *cell = (ProfileEditSectionTitleTableCell * ) view.cell;
    if (!cell) {
        cell = [tableView dequeueReusableCellWithIdentifier:@"ProfileEditSectionTitleTableCell"];
        view.cell = cell;
    }

    // Do something with your cell

    return view;
}

Try using the SO_REUSEADDR socket option before binding the socket.

comSocket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

Edit: I see you're still having trouble with this. There is a case where SO_REUSEADDR won't work. If you try to bind a socket and reconnect to the same destination (with SO_REUSEADDR enabled), then TIME_WAIT will still be in effect. It will however allow you to connect to a different host:port.

A couple of solutions come to mind. You can either continue retrying until you can gain a connection again. Or if the client initiates the closing of the socket (not the server), then it should magically work.

Say you have defined your class like this:

    @Data
    @AllArgsConstructor(staticName = "of")
    private class Pair<P,Q> {

        public P first;
        public Q second;
    }

So when you will need to create a new instance, it will need to take the parameters and you will provide it like this as defined in the annotation.

Pair<Integer, String> pair = Pair.of(menuItemId, category);

If you define it like this, you will get the error asked for.

Pair<Integer, String> pair = new Pair(menuItemId, category);

The environment variable PYTHONPATH is actually only added to the list of locations Python searches for modules. You can print out the full list in the terminal like this:

python -c "import sys; print(sys.path)"

Or if want the output in the UNIX directory list style (separated by :) you can do this:

python -c "import sys; print(':'.join(x for x in sys.path if x))"

Which will output something like this:

/usr/local/lib/python2.7/dist-packages/feedparser-5.1.3-py2.7.egg:/usr/local/lib/
python2.7/dist-packages/stripogram-1.5-py2.7.egg:/home/qiime/lib:/home/debian:/us

The command to just stream it to a new container (mp4) needed by some applications like Adobe Premiere Pro without encoding (fast) is:

ffmpeg -i input.mov -qscale 0 output.mp4

Alternative as mentioned in the comments, which re-encodes with best quaility (-qscale 0):

ffmpeg -i input.mov -q:v 0 output.mp4

These days, if you use two different video formats (WebM and HEVC), you can have a transparent video that works in all of the major browsers except Internet Explorer with a simple <video> tag:

<video>
  <source src="video.webm" type="video/webm">
  <source src="video.mov" type="video/quicktime">
</video>

Here's a demo you can test with

I just want to add that there is another Lifecycle hook called DoCheck that is useful if the @Input value is not a primitive value.

I have an Array as an Input so this does not fire the OnChanges event when the content changes (because the checking that Angular does is 'simple' and not deep so the Array is still an Array, even though the content on the Array has changed).

I then implement some custom checking code to decide if I want to update my view with the changed Array.

You have to use the SelectMany extension method or its equivalent syntax in pure LINQ.

(from model in list
 where model.application == "applicationname"
 from user in model.users
 where user.surname == "surname"
 select new { user, model }).ToList();

This happened to me when an web request endpoint was switched to another server that accepted TLS1.2 requests only. Tried so many attempts mostly found on Stackoverflow like

1. Registry Keys ,
2. Added :
   System.Net.ServicePointManager.SecurityProtocol |= System.Net.SecurityProtocolType.Tls12; to Global.ASX OnStart,
3. Added in Web.config.
4. Updated .Net framework to 4.7.2 Still getting same Exception.

The exception received did no make justice to the actual problem I was facing and found no help from the service operator.

To solve this I have to add a new Cipher Suite TLS_DHE_RSA_WITH_AES_256_GCM_SHA384 I have used IIS Crypto 2.0 Tool from here as shown below.

Yet another solution (Monday is the first day):

I encountered the same error and after the investigation, I found that library selenium-api 2.41.0 requires guava 15.0 but it was overridden by an older version so I declared guava 15.0 as a direct dependency by adding following configuration in pom.xml:

<dependency>
        <artifactId>guava</artifactId>
        <groupId>com.google.guava</groupId>
        <type>jar</type>
        <version>15.0</version>
</dependency>

String string = "abcde"; // The String which Need To Be Converted
JsonObject convertedObject = new Gson().fromJson(string, JsonObject.class);

I do this, and it worked.

It really depends on what functions you're using to plot the lines, but try see if the on you're using takes an alpha value and set it to something like 0.5. If that doesn't work, try get the line objects and set their alpha values directly.

Another simple way :)

public IQueryable<Product> GetProducts(int categoryID)
{
    var productList = db.Products
        .Where(p => p.CategoryID == categoryID)
        .Select(item => 
            new Product
            {
                Name = item.Name
            })
        .ToList()
        .AsQueryable(); // actually it's not useful after "ToList()" :D

    return productList;
}

When you correct the measurements - as mentioned above: Any and Exists, and adding average - we'll get following output:

Executing search Exists() 1000 times ... 
Average Exists(): 35566,023
Fastest Exists() execution: 32226 

Executing search Any() 1000 times ... 
Average Any(): 58852,435
Fastest Any() execution: 52269 ticks

Benchmark finished. Press any key.

This was my solution, works as a charm!

    $(document).on('mouseover', 'input, span', function() {
      var needEllipsis = $(this).css('text-overflow') && (this.offsetWidth < this.scrollWidth);
      var hasNotTitleAttr = typeof $(this).attr('title') === 'undefined';
      if (needEllipsis === true) {
          if(hasNotTitleAttr === true){
            $(this).attr('title', $(this).val());
          }
      }
      if(needEllipsis === false && hasNotTitleAttr == false){
        $(this).removeAttr('title');
      }
  });

There are several ways to accomplish that in Vim. I don't know which are most similar to Sublime Text's though.

The first one would be via multiline insert mode. Put your cursor to the second "a" in the first line, press Ctrl-V, select all lines, then press I, and put in a doublequote. Pressing <esc> will repeat the operation on every line.

The second one is via macros. Put the cursor on the first character, and start recording a macro with qa. Go the your right with llll, enter insert mode with a, put down a doublequote, exit insert mode, and go back to the beginning of your row with <home> (or equivalent). Press j to move down one row. Stop recording with q. And then replay the macro with @a. Several times.

Does any of the above approaches work for you?

In cases where the private method is not void and the return value is used as a parameter to an external dependency's method, you can mock the dependency and use an ArgumentCaptor to capture the return value. For example:

ArgumentCaptor<ByteArrayOutputStream> csvOutputCaptor = ArgumentCaptor.forClass(ByteArrayOutputStream.class);
//Do your thing..
verify(this.awsService).uploadFile(csvOutputCaptor.capture());
....
assertEquals(csvOutputCaptor.getValue().toString(), "blabla");

Send your data with SESSION rather than post.

session_start();
$_SESSION['foo'] = "bar";

On the page where you recieve the request, if you absolutely need POST data (some weird logic), you can do this somwhere at the beginning:

$_POST['foo'] = $_SESSION['foo'];

The post data will be valid just the same as if it was sent with POST.

Then destroy the session (or just unset the fields if you need the session for other purposes).

It is important to destroy a session or unset the fields, because unlike POST, SESSION will remain valid until you explicitely destroy it or until the end of browser session. If you don't do it, you can observe some strange results. For example: you use sesson for filtering some data. The user switches the filter on and gets filtered data. After a while, he returns to the page and expects the filter to be reset, but it's not: he still sees filtered data.

Today NodeJS supports new async/await syntax. This is an easy syntax and makes the life much easier

async function process(promises) { // must be an async function
    let x = await Promise.all(promises);  // now x will be an array
    x = x.map( tmp => tmp * 10);              // proccessing the data.
}

const promises = [
   new Promise(resolve => setTimeout(resolve, 0, 1)),
   new Promise(resolve => setTimeout(resolve, 0, 2))
];

process(promises)

Yes you can, just pass the integer param to the split method

In Python everything is an object. When an object is said to be iterable, it means that you can step through (i.e. iterate) the object as a collection.

Arrays for example are iterable. You can step through them with a for loop, and go from index 0 to index n, n being the length of the array object minus 1.

Dictionaries (pairs of key/value, also called associative arrays) are also iterable. You can step through their keys.

Obviously the objects which are not collections are not iterable. A bool object for example only have one value, True or False. It is not iterable (it wouldn't make sense that it's an iterable object).

Update

Based on Manipulating the browser history, passing the empty string as second parameter of pushState method (aka title) should be safe against future changes to the method, so it's better to use pushState like this:

history.pushState(null, '', '/en/step2');    

You can read more about that in mentioned article

Original Answer

Use history.pushState like this:

history.pushState(null, null, '/en/step2');

• More info (MDN article): Manipulating the browser history
• Can I use
• Maybe you should take a look @ Does Internet Explorer support pushState and replaceState?

Update 2 to answer Idan Dagan's comment:

Why not using history.replaceState()?

From MDN

history.replaceState() operates exactly like history.pushState() except that replaceState() modifies the current history entry instead of creating a new one

That means if you use replaceState, yes the url will be changed but user can not use Browser's Back button to back to prev. state(s) anymore (because replaceState doesn't add new entry to history) and it's not recommended and provide bad UX.

Update 3 to add window.onpopstate

So, as this answer got your attention, here is additional info about manipulating the browser history, after using pushState, you can detect the back/forward button navigation by using window.onpopstate like this:

window.onpopstate = function(e) {
    // ... 
};

As the first argument of pushState is an object, if you passed an object instead of null, you can access that object in onpopstate which is very handy, here is how:

window.onpopstate = function(e) {
    if(e.state) {
        console.log(e.state);
    }
};

Update 4 to add Reading the current state:

When your page loads, it might have a non-null state object, you can read the state of the current history entry without waiting for a popstate event using the history.state property like this:

console.log(history.state);

Bonus: Use following to check history.pushState support:

if (history.pushState) {
  // \o/
}

Check out the opensource Forge project. It provides a JavaScript TLS implementation, along with some Flash to handle the actual cross-domain requests:

http://github.com/digitalbazaar/forge/blob/master/README

In short, Forge will enable you to make XmlHttpRequests from a web page loaded over http to an https site. You will need to provide a Flash cross-domain policy file via your server to enable the cross-domain requests. Check out the blog posts at the end of the README to get a more in-depth explanation for how it works.

However, I should mention that Forge is better suited for requests between two different https-domains. The reason is that there's a potential MiTM attack. If you load the JavaScript and Flash from a non-secure site it could be compromised. The most secure use is to load it from a secure site and then use it to access other sites (secure or otherwise).

Thowable catches really everything even ThreadDeath which gets thrown by default to stop a thread from the now deprecated Thread.stop() method. So by catching Throwable you can be sure that you'll never leave the try block without at least going through your catch block, but you should be prepared to also handle OutOfMemoryError and InternalError or StackOverflowError.

Catching Throwable is most useful for outer server loops that delegate all sorts of requests to outside code but may itself never terminate to keep the service alive.

All have given a very good explanation. I am still posting my answer just to give an example if that can help.

// break statement
for (int i = 0; i < 5; i++) {
    if (i == 3) {
        break; // It will force to come out from the loop
    }

    lblDisplay.Text = lblDisplay.Text + i + "[Printed] ";
}

Here is the output:

0[Printed] 1[Printed] 2[Printed]

So 3[Printed] & 4[Printed] will not be displayed as there is break when i == 3

//continue statement
for (int i = 0; i < 5; i++) {
    if (i == 3) {
        continue; // It will take the control to start point of loop
    }

    lblDisplay.Text = lblDisplay.Text + i + "[Printed] ";
}

Here is the output:

0[Printed] 1[Printed] 2[Printed] 4[Printed]

So 3[Printed] will not be displayed as there is continue when i == 3

I suggest you to use URL rewrite mod is enough for your problem,I have the same problem but using URL rewrite mod and getting good SEO response. I can give you a small example. Example is that you consider WordPress , here the data is stored in database but using URL rewrite mod many WordPress websites getting good responses from Google and got rank also.

Example: wordpress url with out url rewrite mod -- domain.com/?p=123 after url rewrite mode -- domain.com/{title of article} like domain.com/seo-url-rewrite-mod

i think you have understood what i want to say you

Host Manager is a web application inside of Tomcat that creates/removes Virtual Hosts within Tomcat.

A Virtual Host allows you to define multiple hostnames on a single server, so you can use the same server to handles requests to, for example, ren.myserver.com and stimpy.myserver.com.

Unfortunately documentation on the GUI side of the Host Manager doesn't appear to exist, but documentation on configuring the virtual hosts manually in context.xml is here:

http://tomcat.apache.org/tomcat-7.0-doc/virtual-hosting-howto.html.

The full explanation of the Host parameters you can find here:

http://tomcat.apache.org/tomcat-7.0-doc/config/host.html.

Adding a virtual host

Once you have access to the host-manager (see other answers on setting up the permissions, the GUI will let you add a (temporary - see edit at the end of this post) virtual host.

At a minimum you need the Name and App Base fields defined. Tomcat will then create the following directories:

{CATALINA_HOME}\conf\Catalina\{Name}
{CATALINA_HOME}\{App Base}

• App Base will be where web applications will be deployed to the virtual host. Can be relative or absolute.
• Name is usually the fully-qualified domain name (e.g. ren.myserver.com)
• Alias can be used to extend the Name also where two addresses should resolve to the same host (e.g. www.ren.myserver.com). Note that this needs to be reflected in DNS records.

The checkboxes are as follows:

• Auto Deploy: Automatically redeploy applications placed into App Base. Dangerous for Production environments!
• Deploy On Startup: Automatically boot up applications under App Base when Tomcat starts
• Deploy XML: Determines whether to parse the application's /META-INF/context.xml
• Unpack WARs: Unpack WAR files placed or uploaded to the App Base, as opposed to running them directly from the WAR.
• Tomcat 8 Copy XML: Copy an application's META-INF/context.xml to the App Base/XML Base on deployment, and use that exclusively, regardless of whether the application is updated. Irrelevant if Deploy XML is false.
• Manager App: Add the manager application to the Virtual Host (Useful for controlling the applications you might have underneath ren.myserver.com)

Update: After playing around with this same process on Tomcat8, the behaviour I'm seeing is that adding a virtual host via the GUI isn't persistent - it doesn't get written to server.xml, even on shutdown. Therefore (unless I'm doing something terribly wrong), you can create it in the GUI, but you'll need to edit server.xml anyway, as per the first link above, to make it stick.

You can call either string's compareTo method (java.lang.String.compareTo). This feature is well documented on the java documentation site.

Here is a short program that demonstrates it:

class StringCompareExample {
    public static void main(String args[]){
        String s1 = "Project"; String s2 = "Sunject";
        verboseCompare(s1, s2);
        verboseCompare(s2, s1);
        verboseCompare(s1, s1);
    }

    public static void verboseCompare(String s1, String s2){
        System.out.println("Comparing \"" + s1 + "\" to \"" + s2 + "\"...");

        int comparisonResult = s1.compareTo(s2);
        System.out.println("The result of the comparison was " + comparisonResult);

        System.out.print("This means that \"" + s1 + "\" ");
        if(comparisonResult < 0){
            System.out.println("lexicographically precedes \"" + s2 + "\".");
        }else if(comparisonResult > 0){
            System.out.println("lexicographically follows \"" + s2 + "\".");
        }else{
            System.out.println("equals \"" + s2 + "\".");
        }
        System.out.println();
    }
}

Here is a live demonstration that shows it works: http://ideone.com/Drikp3

You did everything except copying the new pixel value back to the image.

This line takes a copy of the pixel into a local variable:

Vec3b color = image.at<Vec3b>(Point(x,y));

So, after changing color as you require, just set it back like this:

image.at<Vec3b>(Point(x,y)) = color;

So, in full, something like this:

Mat image = img;
for(int y=0;y<img.rows;y++)
{
    for(int x=0;x<img.cols;x++)
    {
        // get pixel
        Vec3b & color = image.at<Vec3b>(y,x);

        // ... do something to the color ....
        color[0] = 13;
        color[1] = 13;
        color[2] = 13;

        // set pixel
        //image.at<Vec3b>(Point(x,y)) = color;
        //if you copy value
    }
}

let rateUrl = "itms-apps://itunes.apple.com/app/idYOUR_APP_ID?action=write-review"
if UIApplication.shared.canOpenURL(rateUrl) {
    UIApplication.shared.openURL(rateUrl)
}

window.location is just what you need. Other thing you can do is to create anchor element and simulate click on it

$("<a href='your url'></a>").click(); 

If you are using the AUFS storage driver, you can use my docker-layer script to find any container's filesystem root (mnt) and readwrite layer :

# docker-layer musing_wiles
rw layer : /var/lib/docker/aufs/diff/c83338693ff190945b2374dea210974b7213bc0916163cc30e16f6ccf1e4b03f

Edit 2018-03-28 :
docker-layer has been replaced by docker-backup

There's the more general but perhaps not as helpful to you Wireshark.

One of the SO server sites might be better suited for your question. In fact, it's already been asked on SuperUser.

The instance of the inner class is created when instance of the outer class is created. Therefore the members and methods of the inner class have access to the members and methods of the instance (object) of the outer class. When the instance of the outer class goes out of scope, also the inner class instances cease to exist.

The static nested class doesn't have a concrete instance. It's just loaded when it's used for the first time (just like the static methods). It's a completely independent entity, whose methods and variables doesn't have any access to the instances of the outer class.

The static nested classes are not coupled with the outer object, they are faster, and they don't take heap/stack memory, because its not necessary to create instance of such class. Therefore the rule of thumb is to try to define static nested class, with as limited scope as possible (private >= class >= protected >= public), and then convert it to inner class (by removing "static" identifier) and loosen the scope, if it's really necessary.

The accepted solution from Dallas was working for us if we use Load Balancer on the Citrix Netscaler (without WAF policy).

The download of the file doesn't work through the LB of the Netscaler when it is associated with WAF as the current scenario (Content-length not being correct) is a RFC violation and AppFW resets the connection, which doesn't happen when WAF policy is not associated.

So what was missing was:

Response.End();

you can use 'capture.output' like below. This allows you to use the data later:

log <- capture.output({
  test <- CensReg.SMN(cc=cc,x=x,y=y, nu=NULL, type="Normal")
})

class App():
    def __init__(self):
        self.root = Tkinter.Tk()
        button = Tkinter.Button(self.root, text = 'root quit', command=self.quit)
        button.pack()
        self.root.mainloop()

    def quit(self):
        self.root.destroy()

app = App()

In my case, The syntax was correct, yet I had that error when a class calls a second class within the same DLL. the CPP file of the second class had the wrong Properties->Item Type inside visual studio, in my case it was set to C/C++ Header instead of the correct one C/C++ compiler so the compiler didn't compile the CPP file while building it and cause the Error LNK2019

here's an example, Assuming the syntax is correct you should get the error by changing the item type in properties

//class A header file 
class ClassB; // FORWARD DECLERATION
class ClassA
{
public:
ClassB* bObj;
ClassA(HINSTANCE hDLL) ;
//  member functions
}
--------------------------------
//class A cpp file   
ClassA::ClassA(HINSTANCE hDLL) 
{
    bObj = new ClassB();// LNK2019 occures here 
    bObj ->somefunction();// LNK2019 occures here
}
/*************************/

//classB Header file
struct mystruct{}
class ClassB{
public:
ClassB();
mystruct somefunction();
}

------------------------------
//classB cpp file  
/* This is the file with the wrong property item type in visual studio --C/C++ Header-*/
ClassB::somefunction(){}
ClassB::ClassB(){}

You can use "translateX(-100%)" and "text-align: right" if your absolute element is "display: inline-block"

<div class="box">
<div class="absolute-right"></div>
</div>

<style type="text/css">
.box{
    text-align: right;
}
.absolute-right{
    display: inline-block;
    position: absolute;
}

/*The magic:*/
.absolute-right{
-moz-transform: translateX(-100%);
-ms-transform: translateX(-100%);
-webkit-transform: translateX(-100%);
-o-transform: translateX(-100%);
transform: translateX(-100%);
}
</style>

You will get absolute-element aligned to the right relative its parent

Basically I use Fiddler or Postman for testing API's.

In fiddler, in request header you need to specify instead of xml, html you need to change it to json. Eg: Accept: application/json. That should do the job.

mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);

I am not sure if there is a mysql version of this but adding this line of code allows throwing mysqli_sql_exception.
I know, passed a lot of time and the question is already checked answered but I got a different answer and it may be helpful.

All good, but for styleNode.cssText to work in IE6 with node created by javascipt, you need to append the node to the document before you set the cssText;

[ |\t]+$ with an empty replace works. \s+($) with a $1 replace also works. At least in Visual Studio Code...

You should use the TryParse method for the int

string text1 = "x";
    int num1;
    bool res = int.TryParse(text1, out num1);
    if (res == false)
    {
        // String is not a number.
    }

When you go to a stream url, you get offered a file. feed this file to a parser to extract the contents out of it. the file is (usually) plain text and contains the url to play.

I imagine that you're calling your download in a background thread such as provided by a SwingWorker. If so, then simply call your next code sequentially in the same SwingWorker's doInBackground method.

Do this: List<Class> myArray= new ArrayList<Class>();

If you're inside an iframe that don't have cross domain src, or src is empty:

Then:

function getOriginUrl() {
    var href = document.location.href;
    var referrer = document.referrer;
    // Check if window.frameElement not null
    if(window.frameElement) {
        href = window.frameElement.ownerDocument.location.href;
        // This one will be origin
        if(window.frameElement.ownerDocument.referrer != "") {
            referrer = window.frameElement.ownerDocument.referrer;
        }
    }
    // Compare if href not equal to referrer
    if(href != referrer) {
        // Take referrer as origin
        return referrer;
    } else {
        // Take href
        return href
    }
}

If you're inside an iframe with cross domain src:

Then:

function getOriginUrl() {
    var href = document.location.href;
    var referrer = document.referrer;
    // Detect if you're inside an iframe
    if(window.parent != window) {
        // Take referrer as origin
        return referrer;
    } else {
        // Take href
        return href;
    }
}

Hard Real-Time

The hard real-time definition considers any missed deadline to be a system failure. This scheduling is used extensively in mission critical systems where failure to conform to timing constraints results in a loss of life or property.

Examples:

• Air France Flight 447 crashed into the ocean after a sensor malfunction caused a series of system errors. The pilots stalled the aircraft while responding to outdated instrument readings. All 12 crew and 216 passengers were killed.

• Mars Pathfinder spacecraft was nearly lost when a priority inversion caused system restarts. A higher priority task was not completed on time due to being blocked by a lower priority task. The problem was corrected and the spacecraft landed successfully.

• An Inkjet printer has a print head with control software for depositing the correct amount of ink onto a specific part of the paper. If a deadline is missed then the print job is ruined.

Firm Real-Time

The firm real-time definition allows for infrequently missed deadlines. In these applications the system can survive task failures so long as they are adequately spaced, however the value of the task's completion drops to zero or becomes impossible.

Examples:

• Manufacturing systems with robot assembly lines where missing a deadline results in improperly assembling a part. As long as ruined parts are infrequent enough to be caught by quality control and not too costly, then production continues.

• A digital cable set-top box decodes time stamps for when frames must appear on the screen. Since the frames are time order sensitive a missed deadline causes jitter, diminishing quality of service. If the missed frame later becomes available it will only cause more jitter to display it, so it's useless. The viewer can still enjoy the program if jitter doesn't occur too often.

Soft Real-Time

The soft real-time definition allows for frequently missed deadlines, and as long as tasks are timely executed their results continue to have value. Completed tasks may have increasing value up to the deadline and decreasing value past it.

Examples:

• Weather stations have many sensors for reading temperature, humidity, wind speed, etc. The readings should be taken and transmitted at regular intervals, however the sensors are not synchronized. Even though a sensor reading may be early or late compared with the others it can still be relevant as long as it is close enough.

• A video game console runs software for a game engine. There are many resources that must be shared between its tasks. At the same time tasks need to be completed according to the schedule for the game to play correctly. As long as tasks are being completely relatively on time the game will be enjoyable, and if not it may only lag a little.

When do you choose functional programming over object oriented?

When you anticipate a different kind of software evolution:

• Object-oriented languages are good when you have a fixed set of operations on things, and as your code evolves, you primarily add new things. This can be accomplished by adding new classes which implement existing methods, and the existing classes are left alone.

• Functional languages are good when you have a fixed set of things, and as your code evolves, you primarily add new operations on existing things. This can be accomplished by adding new functions which compute with existing data types, and the existing functions are left alone.

When evolution goes the wrong way, you have problems:

• Adding a new operation to an object-oriented program may require editing many class definitions to add a new method.

• Adding a new kind of thing to a functional program may require editing many function definitions to add a new case.

This problem has been well known for many years; in 1998, Phil Wadler dubbed it the "expression problem". Although some researchers think that the expression problem can be addressed with such language features as mixins, a widely accepted solution has yet to hit the mainstream.

What are the typical problem definitions where functional programming is a better choice?

Functional languages excel at manipulating symbolic data in tree form. A favorite example is compilers, where source and intermediate languages change seldom (mostly the same things), but compiler writers are always adding new translations and code improvements or optimizations (new operations on things). Compilation and translation more generally are "killer apps" for functional languages.

To extract number :

var arrNumber = new Array();
$('input[type=number]').each(function(){
    arrNumber.push($(this).val());
})

To extract text:

var arrText= new Array();
$('input[type=text]').each(function(){
    arrText.push($(this).val());
})

Edit : .map implementation

var arrText= $('input[type=text]').map(function(){
    return this.value;
}).get();

Now Junit5 provides a way to assert the exceptions

You can test both general exceptions and customized exceptions

A general exception scenario:

ExpectGeneralException.java

public void validateParameters(Integer param ) {
    if (param == null) {
        throw new NullPointerException("Null parameters are not allowed");
    }
}

ExpectGeneralExceptionTest.java

@Test
@DisplayName("Test assert NullPointerException")
void testGeneralException(TestInfo testInfo) {
    final ExpectGeneralException generalEx = new ExpectGeneralException();

     NullPointerException exception = assertThrows(NullPointerException.class, () -> {
            generalEx.validateParameters(null);
        });
    assertEquals("Null parameters are not allowed", exception.getMessage());
}

You can find a sample to test CustomException here : assert exception code sample

ExpectCustomException.java

public String constructErrorMessage(String... args) throws InvalidParameterCountException {
    if(args.length!=3) {
        throw new InvalidParameterCountException("Invalid parametercount: expected=3, passed="+args.length);
    }else {
        String message = "";
        for(String arg: args) {
            message += arg;
        }
        return message;
    }
}

ExpectCustomExceptionTest.java

@Test
@DisplayName("Test assert exception")
void testCustomException(TestInfo testInfo) {
    final ExpectCustomException expectEx = new ExpectCustomException();

     InvalidParameterCountException exception = assertThrows(InvalidParameterCountException.class, () -> {
            expectEx.constructErrorMessage("sample ","error");
        });
    assertEquals("Invalid parametercount: expected=3, passed=2", exception.getMessage());
}

After making changes to .profile, you need to execute the file, in order for the changes to take effect.

root@masternode# . ~/.profile

Once this is done, the echo command will work.

You are indeed passing the first data item to the each function.

Pass data.programs to the each function instead. Change the code to as below:

<script>     
    $(document).ready(function() {         
        var data = { "programs": [ { "name":"zonealarm", "price":"500" }, { "name":"kaspersky", "price":"200" } ] };         
        $.each(data.programs, function(key,val) {             
            alert(key+val);         
        });     
    }); 
</script> 

Here's an example to get ASM-7 using Maven 3.6:

mvn dependency:get -DremoteRepositories=maven.apache.org -Dartifact=org.ow2.asm:7.0:sources:jar

Or you can download the jar from here: https://search.maven.org/search?q=g:org.ow2.asm%20AND%20a:asm and then

mvn install:install-file -DgroupId=org.ow2.asm -DartifactId=asm -Dversion=7.0 -Dclassifier=sources -Dpackaging=jar -Dfile=/path/to/asm-7.0.jar

Here's a simple function I wrote to display tabular data without having to input each column name: (Also, be aware: Nested looping)

function display_data($data) {
    $output = '<table>';
    foreach($data as $key => $var) {
        $output .= '<tr>';
        foreach($var as $k => $v) {
            if ($key === 0) {
                $output .= '<td><strong>' . $k . '</strong></td>';
            } else {
                $output .= '<td>' . $v . '</td>';
            }
        }
        $output .= '</tr>';
    }
    $output .= '</table>';
    echo $output;
}

UPDATED FUNCTION BELOW

Hi Jack,

your function design is fine, but this function always misses the first dataset in the array. I tested that.

Your function is so fine, that many people will use it, but they will always miss the first dataset. That is why I wrote this amendment.

The missing dataset results from the condition if key === 0. If key = 0 only the columnheaders are written, but not the data which contains $key 0 too. So there is always missing the first dataset of the array.

You can avoid that by moving the if condition above the second foreach loop like this:

function display_data($data) {
    $output = "<table>";
    foreach($data as $key => $var) {
        //$output .= '<tr>';
        if($key===0) {
            $output .= '<tr>';
            foreach($var as $col => $val) {
                $output .= "<td>" . $col . '</td>';
            }
            $output .= '</tr>';
            foreach($var as $col => $val) {
                $output .= '<td>' . $val . '</td>';
            }
            $output .= '</tr>';
        }
        else {
            $output .= '<tr>';
            foreach($var as $col => $val) {
                $output .= '<td>' . $val . '</td>';
            }
            $output .= '</tr>';
        }
    }
    $output .= '</table>';
    echo $output;
}

Best regards and thanks - Axel Arnold Bangert - Herzogenrath 2016

and another update that removes redundant code blocks that hurt maintainability of the code.

function display_data($data) {
$output = '<table>';
foreach($data as $key => $var) {
    $output .= '<tr>';
    foreach($var as $k => $v) {

            $output .= '<td><strong>' . $k . '</strong></td>';
        } else {

Convert the image to a byte[] and store that in the database.

Add this column to your model:

public byte[] Content { get; set; }

Then convert your image to a byte array and store that like you would any other data:

public byte[] ImageToByteArray(System.Drawing.Image imageIn)
{
    using(var ms = new MemoryStream())
    {
        imageIn.Save(ms, System.Drawing.Imaging.ImageFormat.Gif);

        return ms.ToArray();
    }

Source: Fastest way to convert Image to Byte array

var image = new ImageEntity()
{
   Content = ImageToByteArray(image)
};

_context.Images.Add(image);
_context.SaveChanges();

When you want to get the image back, get the byte array from the database and use the ByteArrayToImage and do what you wish with the Image

This stops working when the byte[] gets to big. It will work for files under 100Mb

Cannot comment anymore but voted it up and wanted to let folks know that " works very well for the xml config files when forming regex expressions for RegexTransformer in Solr like so: regex=".*img src="(.*)".*" using the escaped version instead of double-quotes.

When using FragmentPagerAdapter or FragmentStatePagerAdapter, it is best to deal solely with getItem() and not touch instantiateItem() at all. The instantiateItem()-destroyItem()-isViewFromObject() interface on PagerAdapter is a lower-level interface that FragmentPagerAdapter uses to implement the much simpler getItem() interface.

Before getting into this, I should clarify that

if you want to switch out the actual fragments that are being displayed, you need to avoid FragmentPagerAdapter and use FragmentStatePagerAdapter.

An earlier version of this answer made the mistake of using FragmentPagerAdapter for its example - that won't work because FragmentPagerAdapter never destroys a fragment after it's been displayed the first time.

I don't recommend the setTag() and findViewWithTag() workaround provided in the post you linked. As you've discovered, using setTag() and findViewWithTag() doesn't work with fragments, so it's not a good match.

The right solution is to override getItemPosition(). When notifyDataSetChanged() is called, ViewPager calls getItemPosition() on all the items in its adapter to see whether they need to be moved to a different position or removed.

By default, getItemPosition() returns POSITION_UNCHANGED, which means, "This object is fine where it is, don't destroy or remove it." Returning POSITION_NONE fixes the problem by instead saying, "This object is no longer an item I'm displaying, remove it." So it has the effect of removing and recreating every single item in your adapter.

This is a completely legitimate fix! This fix makes notifyDataSetChanged behave like a regular Adapter without view recycling. If you implement this fix and performance is satisfactory, you're off to the races. Job done.

If you need better performance, you can use a fancier getItemPosition() implementation. Here's an example for a pager creating fragments off of a list of strings:

ViewPager pager = /* get my ViewPager */;
// assume this actually has stuff in it
final ArrayList<String> titles = new ArrayList<String>();

FragmentManager fm = getSupportFragmentManager();
pager.setAdapter(new FragmentStatePagerAdapter(fm) {
    public int getCount() {
        return titles.size();
    }

    public Fragment getItem(int position) {
        MyFragment fragment = new MyFragment();
        fragment.setTitle(titles.get(position));
        return fragment;
    }

    public int getItemPosition(Object item) {
        MyFragment fragment = (MyFragment)item;
        String title = fragment.getTitle();
        int position = titles.indexOf(title);

        if (position >= 0) {
            return position;
        } else {
            return POSITION_NONE;
        }
    }
});

With this implementation, only fragments displaying new titles will get displayed. Any fragments displaying titles that are still in the list will instead be moved around to their new position in the list, and fragments with titles that are no longer in the list at all will be destroyed.

What if the fragment has not been recreated, but needs to be updated anyway? Updates to a living fragment are best handled by the fragment itself. That's the advantage of having a fragment, after all - it is its own controller. A fragment can add a listener or an observer to another object in onCreate(), and then remove it in onDestroy(), thus managing the updates itself. You don't have to put all the update code inside getItem() like you do in an adapter for a ListView or other AdapterView types.

One last thing - just because FragmentPagerAdapter doesn't destroy a fragment doesn't mean that getItemPosition is completely useless in a FragmentPagerAdapter. You can still use this callback to reorder your fragments in the ViewPager. It will never remove them completely from the FragmentManager, though.

Another date format

select datediff(day,'20110101','20110301')

Change the content type to 'application/x-www-form-urlencoded'

This is what you need:

 =NOT(ISERROR(MATCH(<cell in col A>,<column B>, 0)))  ## pseudo code

For the first cell of A, this would be:

 =NOT(ISERROR(MATCH(A2,$B$2:$B$5, 0)))

Enter formula (and drag down) as follows:

For Fiddler to capture traffic from localhost on local IIS, there are 3 steps (It worked on my computer):

1. Click Tools > Fiddler Options. Ensure Allow remote clients to connect is checked. Close Fiddler.

2. Create a new DWORD named ReverseProxyForPort inside KEY_CURRENT_USER\SOFTWARE\Microsoft\Fiddler2. Set the DWORD to port 80 (choose decimal here). Restart Fiddler.

3. Add port 8888 to the addresses defined in your client. For example localhost:8888/MyService/WebAPI/v1/

My bible for JPA work is the Java Persistence wikibook. It has a section on unidirectional OneToMany which explains how to do this with a @JoinColumn annotation. In your case, i think you would want:

@OneToMany
@JoinColumn(name="TXTHEAD_CODE")
private Set<Text> text;

I've used a Set rather than a List, because the data itself is not ordered.

The above is using a defaulted referencedColumnName, unlike the example in the wikibook. If that doesn't work, try an explicit one:

@OneToMany
@JoinColumn(name="TXTHEAD_CODE", referencedColumnName="DATREG_META_CODE")
private Set<Text> text;

In a Object Relational Mapping context, every object needs to have a unique identifier. You use the @Id annotation to specify the primary key of an entity.

The @GeneratedValue annotation is used to specify how the primary key should be generated. In your example you are using an Identity strategy which

Indicates that the persistence provider must assign primary keys for the entity using a database identity column.

There are other strategies, you can see more here.

For practically all date and time matters I prefer to simplify things, very, very simple... Down to seconds stored in integers.

Integers will always be supported as integers in databases, flat files, etc. You do a little math and cast it into another type and you can format the date anyway you want.

Doing it this way, you don't have to worry when [insert current favorite database here] is replaced with [future favorite database] which coincidentally didn't use the date format you chose today.

It's just a little math overhead (eg. methods--takes two seconds, I'll post a gist if necessary) and simplifies things for a lot of operations regarding date/time later.

To store actual Unicode codepoints, you have to first decode the String's UTF-16 codeunits to UTF-32 codeunits (which are currently the same as the Unicode codepoints). Use System.Text.Encoding.UTF32.GetBytes() for that, and then write the resulting bytes to the StringBuilder as needed,i.e.

static void Main(string[] args) 
{ 
    String originalString = "This string contains the unicode character Pi(p)"; 
    Byte[] bytes = Encoding.UTF32.GetBytes(originalString);
    StringBuilder asAscii = new StringBuilder();
    for (int idx = 0; idx < bytes.Length; idx += 4)
    { 
        uint codepoint = BitConverter.ToUInt32(bytes, idx);
        if (codepoint <= 127) 
            asAscii.Append(Convert.ToChar(codepoint)); 
        else 
            asAscii.AppendFormat("\\u{0:x4}", codepoint); 
    } 
    Console.WriteLine("Final string: {0}", asAscii); 
    Console.ReadKey(); 
}

Very good answer using inheritance, just remember to override the initializer

public class Utf8StringWriter : StringWriter
{
    public Utf8StringWriter(StringBuilder sb) : base (sb)
    {
    }
    public override Encoding Encoding { get { return Encoding.UTF8; } }
}

You can also try adding the Motumedia PPA to your apt sources and update your ffmpeg packages.

I faced the same issue and was not able to find it out where git.exe is located. After spending so much time I fount that in my windows 8, it is located at

C:\Program Files (x86)\Git\bin

And for command line :

C:\Program Files (x86)\Git\cmd

Hope this helps someone facing the same issue.

Use the isSelected method.

You can also use an ItemListener so you'll be notified when it's checked or unchecked.

I would do this as

if isnumeric(ubound(a)) = False then msgbox "a is empty!"

In IDP Init SSO (Unsolicited Web SSO) the Federation process is initiated by the IDP sending an unsolicited SAML Response to the SP. In SP-Init, the SP generates an AuthnRequest that is sent to the IDP as the first step in the Federation process and the IDP then responds with a SAML Response. IMHO ADFSv2 support for SAML2.0 Web SSO SP-Init is stronger than its IDP-Init support re: integration with 3rd Party Fed products (mostly revolving around support for RelayState) so if you have a choice you'll want to use SP-Init as it'll probably make life easier with ADFSv2.

Here are some simple SSO descriptions from the PingFederate 8.0 Getting Started Guide that you can poke through that may help as well -- https://documentation.pingidentity.com/pingfederate/pf80/index.shtml#gettingStartedGuide/task/idpInitiatedSsoPOST.html

I found the following command to run from command line:

vlc.exe --extraintf=http:logger --verbose=2 --file-logging --logfile=vlc-log.txt

I caught this error a few days ago.

IN my case it was because I was using a Transaction on a Singleton.

.Net does not work well with Singleton as stated above.

My solution was this:

public class DbHelper : DbHelperCore
{
    public DbHelper()
    {
        Connection = null;
        Transaction = null;
    }

    public static DbHelper instance
    {
        get
        {
            if (HttpContext.Current is null)
                return new DbHelper();
            else if (HttpContext.Current.Items["dbh"] == null)
                HttpContext.Current.Items["dbh"] = new DbHelper();

            return (DbHelper)HttpContext.Current.Items["dbh"];
        }
    }

    public override void BeginTransaction()
    {
        Connection = new SqlConnection(Entity.Connection.getCon);
        if (Connection.State == System.Data.ConnectionState.Closed)
            Connection.Open();
        Transaction = Connection.BeginTransaction();
    }
}

I used HttpContext.Current.Items for my instance. This class DbHelper and DbHelperCore is my own class

Here is the right way to do imports in Java.

import Dan.Vik;
class Kab
{
public static void main(String args[])
{
    Vik Sam = new Vik();
    Sam.disp();
}
}

You don't import methods in java. There is an advanced usage of static imports but basically you just import packages and classes. If the function you are importing is a static function you can do a static import, but I don't think you are looking for static imports here.

In case of float values with characters 'e' '+' it errors out if we try to convert in decimal. ('2.81104e+006'). It still pass ISNUMERIC test.

SELECT ISNUMERIC('2.81104e+006') 

returns 1.

SELECT convert(decimal(15,2), '2.81104e+006') 

returns

error: Error converting data type varchar to numeric.

And

SELECT try_convert(decimal(15,2), '2.81104e+006') 

returns NULL.

SELECT convert(float, '2.81104e+006') 

returns the correct value 2811040.

This answer is based on an article that no longer exists:

Summary of article:

"Basically, WCF is a service layer that allows you to build applications that can communicate using a variety of communication mechanisms. With it, you can communicate using Peer to Peer, Named Pipes, Web Services and so on.

You can’t compare them because WCF is a framework for building interoperable applications. If you like, you can think of it as a SOA enabler. What does this mean?

Well, WCF conforms to something known as ABC, where A is the address of the service that you want to communicate with, B stands for the binding and C stands for the contract. This is important because it is possible to change the binding without necessarily changing the code. The contract is much more powerful because it forces the separation of the contract from the implementation. This means that the contract is defined in an interface, and there is a concrete implementation which is bound to by the consumer using the same idea of the contract. The datamodel is abstracted out."

... later ...

"should use WCF when we need to communicate with other communication technologies (e,.g. Peer to Peer, Named Pipes) rather than Web Service"

You could also use plain Javascript window.innerWidth to compare width.

But use jQuery's .resize() fired automatically for you:

$( window ).resize(function() {
  // your code...
});

//Recursive solution
class SLL
{
   int data;
   SLL next;
}

SLL reverse(SLL head)
{
  //base case - 0 or 1 elements
  if(head == null || head.next == null) return head;

  SLL temp = reverse(head.next);
  head.next.next = head;
  head.next = null;
  return temp;
}

Below I sum up Prateek Joshi's awesome explanation.

The theory:

• URI (uniform resource identifier) identifies a resource (text document, image file, etc)
• URL (uniform resource locator) is a subset of the URIs that include a network location
• URN (uniform resource name) is a subset of URIs that include a name within a given space, but no location

That is:

And for an example:

Also, if you haven't already, I suggest reading Roger Pate's answer.

Try the following I found Here's a link

If your app targets M and above and declares as using the CAMERA permission which is not granted, then attempting to use this action will result in a SecurityException.

EasyImage.openCamera(Activity activity, int type);

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    EasyImage.handleActivityResult(requestCode, resultCode, data, this, new DefaultCallback() {
        @Override
        public void onImagePickerError(Exception e, EasyImage.ImageSource source, int type) {
            //Some error handling
        }

        @Override
        public void onImagesPicked(List<File> imagesFiles, EasyImage.ImageSource source, int type) {
            //Handle the images
            onPhotosReturned(imagesFiles);
        }
    });
}

You cannot compare date-strings. It is good habit to use PHP's DateTime object instead:

$paymentDate = new DateTime(); // Today
echo $paymentDate->format('d/m/Y'); // echos today! 
$contractDateBegin = new DateTime('2001-01-01');
$contractDateEnd  = new DateTime('2015-01-01');

if (
  $paymentDate->getTimestamp() > $contractDateBegin->getTimestamp() && 
  $paymentDate->getTimestamp() < $contractDateEnd->getTimestamp()){
  echo "is between";
}else{
   echo "NO GO!";  
}

I put this question to the IETF HTTP WG. The comment from Roy Fielding (author of http/1.1 document in 1998) was that

"... an implementation would be broken to do anything other than to parse and discard that body if received"

RFC 7213 (HTTPbis) states:

"A payload within a GET request message has no defined semantics;"

It seems clear now that the intention was that semantic meaning on GET request bodies is prohibited, which means that the request body can't be used to affect the result.

There are proxies out there that will definitely break your request in various ways if you include a body on GET.

So in summary, don't do it.

ByteBuffer has this capability, and is able to work with both little and big endian integers.

Consider this example:

//  read the file into a byte array
File file = new File("file.bin");
FileInputStream fis = new FileInputStream(file);
byte [] arr = new byte[(int)file.length()];
fis.read(arr);

//  create a byte buffer and wrap the array
ByteBuffer bb = ByteBuffer.wrap(arr);

//  if the file uses little endian as apposed to network
//  (big endian, Java's native) format,
//  then set the byte order of the ByteBuffer
if(use_little_endian)
    bb.order(ByteOrder.LITTLE_ENDIAN);

//  read your integers using ByteBuffer's getInt().
//  four bytes converted into an integer!
System.out.println(bb.getInt());

Hope this helps.

It provides:

1. a constant reference, eg const x = [] - the array can be modified, but x can't point to another array; and

2. block scoping.

const and let will together replace var in ecma6/2015. See discussion at https://strongloop.com/strongblog/es6-variable-declarations/

If you define a class without any constructor, the compiler will synthesize a constructor for you (and that will be a default constructor -- i.e., one that doesn't require any arguments). If, however, you do define a constructor, (even if it does take one or more arguments) the compiler will not synthesize a constructor for you -- at that point, you've taken responsibility for constructing objects of that class, so the compiler "steps back", so to speak, and leaves that job to you.

You have two choices. You need to either provide a default constructor, or you need to supply the correct parameter when you define an object. For example, you could change your constructor to look something like:

Blowfish(BlowfishAlgorithm algorithm = CBC);

...so the ctor could be invoked without (explicitly) specifying an algorithm (in which case it would use CBC as the algorithm).

The other alternative would be to explicitly specify the algorithm when you define a Blowfish object:

class GameCryptography { 
    Blowfish blowfish_;
public:
    GameCryptography() : blowfish_(ECB) {}
    // ...
};

In C++ 11 (or later) you have one more option available. You can define your constructor that takes an argument, but then tell the compiler to generate the constructor it would have if you didn't define one:

class GameCryptography { 
public:

    // define our ctor that takes an argument
    GameCryptography(BlofishAlgorithm); 

    // Tell the compiler to do what it would have if we didn't define a ctor:
    GameCryptography() = default;
};

As a final note, I think it's worth mentioning that ECB, CBC, CFB, etc., are modes of operation, not really encryption algorithms themselves. Calling them algorithms won't bother the compiler, but is unreasonably likely to cause a problem for others reading the code.

Here is directive from the official examples angular docs v1.5 that shows how to compile html:

.directive('compileHtml', function ($compile) {
  return function (scope, element, attrs) {
    scope.$watch(
      function(scope) {
        return scope.$eval(attrs.compileHtml);
      },
      function(value) {
        element.html(value);
        $compile(element.contents())(scope);
      }
    );
  };
});

Usage:

<div compile-html="item.htmlString"></div>

It will insert item.htmlString property as html any place, like

<li ng-repeat="item in itemList">
    <div compile-html="item.htmlString"></div>

Calling flush() can potentially add lots of new entities, so there isnt really the notion of "lastInsertId". However Doctrine will populate the identity fields whenever one is generated, so accessing the id field after calling flush will always contain the ID of a newly "persisted" entity.

Here is another approach using jQuery,

function uniqueArray(array){
  if ($.isArray(array)){
    var dupes = {}; var len, i;
    for (i=0,len=array.length;i<len;i++){
      var test = array[i].toString();
      if (dupes[test]) { array.splice(i,1); len--; i--; } else { dupes[test] = true; }
    }
  } 
  else {
    if (window.console) console.log('Not passing an array to uniqueArray, returning whatever you sent it - not filtered!');
      return(array);
  }
  return(array);
}
