If you pass an Exception class to assertRaises(), a context manager is provided. This can improve the readability of your tests:

# raise exception if Application created with bad data
with self.assertRaises(pySourceAidExceptions.PathIsNotAValidOne):
    application = Application("abcdef", "")

This allows you to test error cases in your code.

In this case, you are testing the PathIsNotAValidOne is raised when you pass invalid parameters to the Application constructor.

I'm going to say right off the bat that you will not be able to achieve the look they have with radio buttons with strictly CSS.

You could, however, stick to the list style in the example you posted and replace the anchors with clickable spans that would trigger a javascript event that would in turn save that rating to your database via ajax.

If you went that route you would probably also want to save a cookie to the users machine so that they could not submit over and over again to your database. That would prevent them from submitting more than once at least until they deleted their cookies.

But of course there are many ways to address this problem. This is just one of them. Hope that helps.

Use a JSON parser, like JSON.NET

string json = "{ \"Atlantic/Canary\": \"GMT Standard Time\", \"Europe/Lisbon\": \"GMT Standard Time\", \"Antarctica/Mawson\": \"West Asia Standard Time\", \"Etc/GMT+3\": \"SA Eastern Standard Time\", \"Etc/GMT+2\": \"UTC-02\", \"Etc/GMT+1\": \"Cape Verde Standard Time\", \"Etc/GMT+7\": \"US Mountain Standard Time\", \"Etc/GMT+6\": \"Central America Standard Time\", \"Etc/GMT+5\": \"SA Pacific Standard Time\", \"Etc/GMT+4\": \"SA Western Standard Time\", \"Pacific/Wallis\": \"UTC+12\", \"Europe/Skopje\": \"Central European Standard Time\", \"America/Coral_Harbour\": \"SA Pacific Standard Time\", \"Asia/Dhaka\": \"Bangladesh Standard Time\", \"America/St_Lucia\": \"SA Western Standard Time\", \"Asia/Kashgar\": \"China Standard Time\", \"America/Phoenix\": \"US Mountain Standard Time\", \"Asia/Kuwait\": \"Arab Standard Time\" }";
var data = (JObject)JsonConvert.DeserializeObject(json);
string timeZone = data["Atlantic/Canary"].Value<string>();

If you don't want to pass the parameter when you don't want to search, then you should make the parameter optional instead of assuming that '' and NULL are the same thing.

ALTER PROCEDURE [dbo].[psProducts] 
(
  @SearchType varchar(50) = NULL
)
AS
BEGIN
  SET NOCOUNT ON;

  SELECT P.[ProductId]
  ,P.[ProductName]
  ,P.[ProductPrice]
  ,P.[Type]
  FROM dbo.[Product] AS P
  WHERE p.[Type] = COALESCE(NULLIF(@SearchType, ''), p.[Type]);
END
GO

Now if you pass NULL, an empty string (''), or leave out the parameter, the where clause will essentially be ignored.

Dynamic creation of a dialog box. You can customize to your taste.

Note there is no external dependency here except winform

private static DialogResult ShowInputDialog(ref string input)
    {
        System.Drawing.Size size = new System.Drawing.Size(200, 70);
        Form inputBox = new Form();

        inputBox.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedDialog;
        inputBox.ClientSize = size;
        inputBox.Text = "Name";

        System.Windows.Forms.TextBox textBox = new TextBox();
        textBox.Size = new System.Drawing.Size(size.Width - 10, 23);
        textBox.Location = new System.Drawing.Point(5, 5);
        textBox.Text = input;
        inputBox.Controls.Add(textBox);

        Button okButton = new Button();
        okButton.DialogResult = System.Windows.Forms.DialogResult.OK;
        okButton.Name = "okButton";
        okButton.Size = new System.Drawing.Size(75, 23);
        okButton.Text = "&OK";
        okButton.Location = new System.Drawing.Point(size.Width - 80 - 80, 39);
        inputBox.Controls.Add(okButton);

        Button cancelButton = new Button();
        cancelButton.DialogResult = System.Windows.Forms.DialogResult.Cancel;
        cancelButton.Name = "cancelButton";
        cancelButton.Size = new System.Drawing.Size(75, 23);
        cancelButton.Text = "&Cancel";
        cancelButton.Location = new System.Drawing.Point(size.Width - 80, 39);
        inputBox.Controls.Add(cancelButton);

        inputBox.AcceptButton = okButton;
        inputBox.CancelButton = cancelButton; 

        DialogResult result = inputBox.ShowDialog();
        input = textBox.Text;
        return result;
    }

usage

string input="hede";
ShowInputDialog(ref input);

This is how you can achieve your desired setup with Bootstrap 3:

<div class="container-fluid">
    <div class="row"> <!-- Give this div your desired background color -->
        <div class="container">
            <div class="row">
                <div class="col-md-12">
                    ... your content here ...
                </div>
            </div>
        </div>
    </div>
</div>

The container-fluid part makes sure that you can change the background over the full width. The container part makes sure that your content is still wrapped in a fixed width.

This approach works, but personally I don't like all the nesting. However, I haven't found a better solution so far.

I had some what similar requirement - to find first day of the month but based on year end month selected by user in their profile page.

Problem statement - find all the txns done by the user in his/her financial year. Financial year is determined using year end month value where month can be any valid month - 1 for Jan, 2 for Feb, 3 for Mar,....12 for Dec.

For some clients financial year ends on March and some observe it on December.

Scenarios - (Today is `08 Aug, 2018`)
   1. If `financial year` ends on `July` then query should return `01 Aug 2018`.
   2. If `financial year` ends on `December` then query should return `01 January 2018`.
   3. If `financial year` ends on `March` then query should return `01 April 2018`.
   4. If `financial year` ends on `September` then query should return `01 October 2017`.

And, finally below is the query. -

select @date := (case when ? >= month(now()) 
then date_format((subdate(subdate(now(), interval (12 - ? + month(now()) - 1) month), interval day(now()) - 2 day)) ,'%Y-%m-01')
else date_format((subdate(now(), interval month(now()) - ? - 1 month)), '%Y-%m-01') end)

where ? is year end month (values from 1 to 12).

As other users have pointed out, we use expression(). I'd like to answer the original question which involves a comma in the subscript:

How can I write v 1,2 with 1,2 as subscripts?

plot(1:10, 11:20 , main=expression(v["1,2"]))

Also, I'd like to add the reference for those looking to find the full expression syntax in R plotting: For more information see the ?plotmath help page. Running demo(plotmath) will showcase many expressions and relevant syntax.

Remember to use * to join different types of text within an expression.

Here is some of the sample output from demo(plotmath):

Sometimes, you really don't care about the collection itself. For instance, creating a simple model fit line to compare an "approximation" with the raw data:

fib_raw = [1, 1, 2, 3, 5, 8, 13, 21] # Fibonacci numbers

phi = (1 + sqrt(5)) / 2
phi2 = (1 - sqrt(5)) / 2

def fib_approx(n): return (phi**n - phi2**n) / sqrt(5)

x = range(len(data))
y = [fib_approx(n) for n in x]

# Now plot to compare fib_raw and y
# Compare error, etc

In this case, the values of the Fibonacci sequence itself were irrelevant. All we needed here was the size of the input sequence we were comparing with.

ghostdog74's example provided the core of what I needed, since I've never written any vbs before and needed to do that. It's not perfect, but I fleshed out the example into a full script in case anyone finds it useful.

'ReplaceText.vbs

Option Explicit

Const ForAppending = 8
Const TristateFalse = 0 ' the value for ASCII
Const Overwrite = True

Const WindowsFolder = 0
Const SystemFolder = 1
Const TemporaryFolder = 2

Dim FileSystem
Dim Filename, OldText, NewText
Dim OriginalFile, TempFile, Line
Dim TempFilename

If WScript.Arguments.Count = 3 Then
    Filename = WScript.Arguments.Item(0)
    OldText = WScript.Arguments.Item(1)
    NewText = WScript.Arguments.Item(2)
Else
    Wscript.Echo "Usage: ReplaceText.vbs <Filename> <OldText> <NewText>"
    Wscript.Quit
End If

Set FileSystem = CreateObject("Scripting.FileSystemObject")
Dim tempFolder: tempFolder = FileSystem.GetSpecialFolder(TemporaryFolder)
TempFilename = FileSystem.GetTempName

If FileSystem.FileExists(TempFilename) Then
    FileSystem.DeleteFile TempFilename
End If

Set TempFile = FileSystem.CreateTextFile(TempFilename, Overwrite, TristateFalse)
Set OriginalFile = FileSystem.OpenTextFile(Filename)

Do Until OriginalFile.AtEndOfStream
    Line = OriginalFile.ReadLine

    If InStr(Line, OldText) > 0 Then
        Line = Replace(Line, OldText, NewText)
    End If 

    TempFile.WriteLine(Line)
Loop

OriginalFile.Close
TempFile.Close

FileSystem.DeleteFile Filename
FileSystem.MoveFile TempFilename, Filename

Wscript.Quit

Run this following command inside the project

npm install --save @bootsrap@4

and if you get a confirmation like this

+ [email protected]
updated 1 package in 8.245s

It means boostrap 4 is successfully installed. However, in order to use it, you need to update the "styles" array under the angular.json file.

Update it the following way so that bootstrap will be able to override the existing styles

"styles": [
          "node_modules/bootstrap/dist/css/bootstrap.min.css",
           "src/styles.css"
          ],

To make sure everything is set up correctly, run ng serve > open browser at http://localhost:4200/ or a port you run the angular app > right click > inspect > under the head check the styles if you have bootsrap like shown below, then you are good to use boostrap.

The first one using str.charAt should be faster.

If you dig inside the source code of String class, we can see that charAt is implemented as follows:

public char charAt(int index) {
    if ((index < 0) || (index >= count)) {
        throw new StringIndexOutOfBoundsException(index);
    }
    return value[index + offset];
}

Here, all it does is index an array and return the value.

Now, if we see the implementation of toCharArray, we will find the below:

public char[] toCharArray() {
    char result[] = new char[count];
    getChars(0, count, result, 0);
    return result;
}

public void getChars(int srcBegin, int srcEnd, char dst[], int dstBegin) {
    if (srcBegin < 0) {
        throw new StringIndexOutOfBoundsException(srcBegin);
    }
    if (srcEnd > count) {
        throw new StringIndexOutOfBoundsException(srcEnd);
    }
    if (srcBegin > srcEnd) {
        throw new StringIndexOutOfBoundsException(srcEnd - srcBegin);
    }
    System.arraycopy(value, offset + srcBegin, dst, dstBegin,
         srcEnd - srcBegin);
}

As you see, it is doing a System.arraycopy which is definitely going to be a tad slower than not doing it.

Go to your project's properties and set the start page property.

1. Go to the project's Properties
2. Go to the Web tab
3. Select the Specific Page radio button
4. Type in the desired url in the Specific Page text box

Set your css in the table cell to

white-space:pre-wrap;

document.body.innerHTML = 'First line\nSecond line\nThird line';

body{ white-space:pre-wrap; }

This is simple way to Display Div using:-

$("#musicinfo").show();  //or
$("#musicinfo").css({'display':'block'});  //or
$("#musicinfo").toggle("slow");   //or
$("#musicinfo").fadeToggle();    //or

I have a SimpleCursorAdapter so I have to duplicate the data for use the respose in this post. So, I recommend you try this way:

for (int i = 0; i < spinnerRegion.getAdapter().getCount(); i++) {
    if (spinnerRegion.getItemIdAtPosition(i) == Integer
        .valueOf(signal.getInt(signal
            .getColumnIndexOrThrow("id_region")))) {
        spinnerRegion.setSelection(i);
        break;
    }
}

I think that is a real way

$("a:lt(n)")

JQuery Documentation

add or remove fragment in viewpager dynamically.
Call setupViewPager(viewPager) on activity start. To load different fragment call setupViewPagerCustom(viewPager). e.g. on button click call: setupViewPagerCustom(viewPager);

    private void setupViewPager(ViewPager viewPager)
{
    ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
    adapter.addFrag(new fragmnet1(), "HOME");
    adapter.addFrag(new fragmnet2(), "SERVICES");

    viewPager.setAdapter(adapter);
}

private void setupViewPagerCustom(ViewPager viewPager)
{

    ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());

    adapter.addFrag(new fragmnet3(), "Contact us");
    adapter.addFrag(new fragmnet4(), "ABOUT US");


    viewPager.setAdapter(adapter);
}

//Viewpageradapter, handles the views

static class ViewPagerAdapter extends FragmentStatePagerAdapter
{
    private final List<Fragment> mFragmentList = new ArrayList<>();
    private final List<String> mFragmentTitleList = new ArrayList<>();

    public ViewPagerAdapter(FragmentManager manager){
        super(manager);
    }

    @Override
    public Fragment getItem(int position) {
        return mFragmentList.get(position);
    }

    @Override
    public int getCount() {
        return mFragmentList.size();
    }

    @Override
    public int getItemPosition(Object object){
        return PagerAdapter.POSITION_NONE;
    }

    public void addFrag(Fragment fragment, String title){
        mFragmentList.add(fragment);
        mFragmentTitleList.add(title);
    }

    @Override
    public CharSequence getPageTitle(int position){
        return mFragmentTitleList.get(position);
    }
}

funny, that in the most answer you create a box with the text (or object), instead of it create the text (or object) div and under that a box with 100% width (or at least what it should) and with height what equal with your "border" px... So, i think this is the most simple and perfect answer:

<h3>Your Text</h3><div class="border-shadow"></div>

and the css:

    .shadow {
        width:100%;
        height:1px; // = "border height (without the shadow)!"
        background:#000; // = "border color!"
        -webkit-box-shadow: 0px 1px 8px 1px rgba(0,0,0,1); // rbg = "border shadow color!"
        -moz-box-shadow: 0px 1px 8px 1px rgba(0,0,0,1); // rbg = "border shadow color!"
        box-shadow: 0px 1px 8px 1px rgba(0,0,0,1); // rbg = "border shadow color!"

}

Here you can experiment with the radius, etc. easy: https://www.cssmatic.com/box-shadow

You could use git remote like:

git fetch origin

and then setup a local branch to track the remote branch like below:

git branch --track [local-branch-name] origin/remote-branch-name

You would now have the contents of the remote github branch in local-branch-name.

You could switch to that local-branch-name and start work:

git checkout [local-branch-name]

<?php
$Words = array("hello","there","world");
$c = 0;

    $message = 'Hi hello';
     foreach ($Words as $word):
        $trial = stripos($message,$word);
        
        if($trial != true){
            $c++;
            echo 'Word '.$c.' didnt match <br> <br>';
        }else{
            $c++;
            echo 'Word '.$c.' matched <br> <br>';
        }
     endforeach;
     ?>

I used this kind of code to check for hello, It also Has a numbering feature. You can use this if you want to do content moderation practices in websites that need the user to type

Note : If you are using iTunes 12.7.0 or above then use Solution 2 else use Solution 1. Solution 1 cannot be used with iTunes 12.7.0 or above since Apps section has been removed from iTunes by Apple

Solution 1 : Using iTunes 12.7 below

Tested on iTunes 12 with Mac OS X (Yosemite) 10.10.3

Also, tested on iTunes 12.3.2.35 with Mac OX X (El Capitan) 10.11.3

This process also applicable for iTunes 12.5.5 with Mac OS X (macOS Sierra) 10.12.3.

You can install IPA file using iTunes 12.x onto device using below steps :

1. Drag-and-drop IPA file into 'Apps' tab of iTunes BEFORE you connect the device.
2. Connect your device
3. Select your device on iTunes
4. Select 'Apps' tab

5. Search app that you want to install

6. Click on 'Install' button. This will change to 'Will Install'

7. Click on 'Apply' button on right corner. This will initiate process of app installation. You can see status on top of iTunes as well as app on device.

8. You can allow new apps to install automatically by enabling checkmark present at bottom.

Solution 2 : Using iTunes 12.7 and above

You can use diawi for this purpose.

1. Open https://www.diawi.com/ in desktop/system browser

2. Drag-and-drop IPA file in empty window. Make sure that last check mark are unselected (recommended due to security concern)

3. Once the upload is completed then press Send button

4. This will generate a link and QR code as well. (You can share this link and QR code with Client)

5. Now open Safari browser in iPhone device and enter this link (Note that link is case-sensitive) OR You can scan the QR using Bakodo iOS app

6. Once link is loaded you can see app details

7. Now select ‘Install application’

8. This will prompt an alert asking permission for installation. Press on Install.

9. Now you can see the app installation begins on screen.

I had a similar issue when trying to access a service (old ASMX service). The call would work when accessing via an IP however when calling with an alias I would get the remote name could not be resolved.

Added the following to the config and it resolved the issue:

<system.net>
    <defaultProxy enabled="true">
    </defaultProxy>
</system.net>

Actually Java supports 4 methods to parse XML out of the box:

DOM Parser/Builder: The whole XML structure is loaded into memory and you can use the well known DOM methods to work with it. DOM also allows you to write to the document with Xslt transformations. Example:

public static void parse() throws ParserConfigurationException, IOException, SAXException {
    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    factory.setValidating(true);
    factory.setIgnoringElementContentWhitespace(true);
    DocumentBuilder builder = factory.newDocumentBuilder();
    File file = new File("test.xml");
    Document doc = builder.parse(file);
    // Do something with the document here.
}

SAX Parser: Solely to read a XML document. The Sax parser runs through the document and calls callback methods of the user. There are methods for start/end of a document, element and so on. They're defined in org.xml.sax.ContentHandler and there's an empty helper class DefaultHandler.

public static void parse() throws ParserConfigurationException, SAXException {
    SAXParserFactory factory = SAXParserFactory.newInstance();
    factory.setValidating(true);
    SAXParser saxParser = factory.newSAXParser();
    File file = new File("test.xml");
    saxParser.parse(file, new ElementHandler());    // specify handler
}

StAx Reader/Writer: This works with a datastream oriented interface. The program asks for the next element when it's ready just like a cursor/iterator. You can also create documents with it. Read document:

public static void parse() throws XMLStreamException, IOException {
    try (FileInputStream fis = new FileInputStream("test.xml")) {
        XMLInputFactory xmlInFact = XMLInputFactory.newInstance();
        XMLStreamReader reader = xmlInFact.createXMLStreamReader(fis);
        while(reader.hasNext()) {
            reader.next(); // do something here
        }
    }
}

Write document:

public static void parse() throws XMLStreamException, IOException {
    try (FileOutputStream fos = new FileOutputStream("test.xml")){
        XMLOutputFactory xmlOutFact = XMLOutputFactory.newInstance();
        XMLStreamWriter writer = xmlOutFact.createXMLStreamWriter(fos);
        writer.writeStartDocument();
        writer.writeStartElement("test");
        // write stuff
        writer.writeEndElement();
    }
}

JAXB: The newest implementation to read XML documents: Is part of Java 6 in v2. This allows us to serialize java objects from a document. You read the document with a class that implements a interface to javax.xml.bind.Unmarshaller (you get a class for this from JAXBContext.newInstance). The context has to be initialized with the used classes, but you just have to specify the root classes and don't have to worry about static referenced classes. You use annotations to specify which classes should be elements (@XmlRootElement) and which fields are elements(@XmlElement) or attributes (@XmlAttribute, what a surprise!)

public static void parse() throws JAXBException, IOException {
    try (FileInputStream adrFile = new FileInputStream("test")) {
        JAXBContext ctx = JAXBContext.newInstance(RootElementClass.class);
        Unmarshaller um = ctx.createUnmarshaller();
        RootElementClass rootElement = (RootElementClass) um.unmarshal(adrFile);
    }
}

Write document:

public static void parse(RootElementClass out) throws IOException, JAXBException {
    try (FileOutputStream adrFile = new FileOutputStream("test.xml")) {
        JAXBContext ctx = JAXBContext.newInstance(RootElementClass.class);
        Marshaller ma = ctx.createMarshaller();
        ma.marshal(out, adrFile);
    }
}

Examples shamelessly copied from some old lecture slides ;-)

Edit: About "which API should I use?". Well it depends - not all APIs have the same capabilities as you see, but if you have control over the classes you use to map the XML document JAXB is my personal favorite, really elegant and simple solution (though I haven't used it for really large documents, it could get a bit complex). SAX is pretty easy to use too and just stay away from DOM if you don't have a really good reason to use it - old, clunky API in my opinion. I don't think there are any modern 3rd party libraries that feature anything especially useful that's missing from the STL and the standard libraries have the usual advantages of being extremely well tested, documented and stable.

Verify current version of python by:

$ python --version

then check python is symbolic link to which file.

  $ ll /usr/bin/python

Output Ex:

 lrwxrwxrwx 1 root root 9 Jun 16  2014 /usr/bin/python -> python2.7*

Check other available versions of python:

$ ls /usr/bin/python*

Output Ex:

/usr/bin/python     /usr/bin/python2.7-config  /usr/bin/python3.4         /usr/bin/python3.4m-config  /usr/bin/python3.6m         /usr/bin/python3m
/usr/bin/python2    /usr/bin/python2-config    /usr/bin/python3.4-config  /usr/bin/python3.6          /usr/bin/python3.6m-config  /usr/bin/python3m-config
/usr/bin/python2.7  /usr/bin/python3           /usr/bin/python3.4m        /usr/bin/python3.6-config   /usr/bin/python3-config     /usr/bin/python-config

If want to change current version of python to 3.6 version edit file ~/.bashrc:

vim ~/.bashrc

add below line in the end of file and save:

alias python=/usr/local/bin/python3.6

To install pip for python 3.6

$ sudo apt-get install python3.6 python3.6-dev
$ sudo curl https://bootstrap.pypa.io/ez_setup.py -o - | sudo python3.6
$ sudo easy_install pip

On Success, check current version of pip:

$ pip3 -V

Output Ex:

pip 1.5.4 from /usr/lib/python3/dist-packages (python 3.6)

Given (almost) everything on unix is a file, and lsof lists open files...

Linux : netstat -putan or lsof | grep TCP

OSX : lsof | grep TCP

Other Unixen : lsof way...

{
  "editor.insertSpaces": true
}

True works for me.

There can be one more reason for such behavior - you delete current working directory.

For example:

# in terminal #1
cd /home/user/myJavaApp

# in terminal #2
rm -rf /home/user/myJavaApp

# in terminal #1
java -jar myJar.jar

Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

You can make two applications listen for the same port on the same network interface.

There can only be one listening socket for the specified network interface and port, but that socket can be shared between several applications.

If you have a listening socket in an application process and you fork that process, the socket will be inherited, so technically there will be now two processes listening the same port.

For a SmoothScroll with Scroll duration:

getListView().smoothScrollToPositionFromTop(position,offset,duration);

Parameters
position -> Position to scroll to
offset ---->Desired distance in pixels of position from the top of the view when scrolling is finished
duration-> Number of milliseconds to use for the scroll

Note: From API 11.

HandlerExploit's answer was what I was looking for, but My listview is quite lengthy and also with alphabet scroller. Then I found that the same function can take other parameters as well :)

Edit:(From AFDs suggestion)

To position the current selection:

int h1 = mListView.getHeight();
int h2 = listViewRow.getHeight();

mListView.smoothScrollToPositionFromTop(position, h1/2 - h2/2, duration);  

If you're sharing code between C and C++, remember to add the following to the shared.hfile:

#ifdef __cplusplus
extern "C" {
#endif

extern int my_global;
/* other extern declarations ... */

#ifdef __cplusplus
}
#endif

ObervableCollection have constructor in which you can pass your list. Quoting MSDN:

 public ObservableCollection(
      List<T> list
 )

Easiest way to set permissions to 777 is to connect to Your server through FTP Application like FileZilla, right click on folder, module_installation, and click Change Permissions - then write 777 or check all permissions.

After some googling I found this:

curl -c cookie.txt -d "LoginName=someuser" -d "password=somepass" https://oursite/a
curl -b cookie.txt https://oursite/b

No idea if it works, but it might lead you in the right direction.

Use the following script tag in your jsp/js file:

<script src="http://code.jquery.com/jquery-1.9.0.js"></script>
<script src="http://code.jquery.com/jquery-migrate-1.2.1.js"></script>

this will work for sure.

I have created this function, or class. Im kinda new but my friend needed this also so I created this:

public String[] name(int index, String[] z ){
    if(index > z.length){
        return z;
    } else {
        String[] returnThis = new String[z.length - 1];
        int newIndex = 0;
        for(int i = 0; i < z.length; i++){
            if(i != index){
                returnThis[newIndex] = z[i];
                newIndex++;
            }
        }
        return returnThis; 
    }
}

Since its pretty revelant, I thought I would post it here.

There are several ways to intercept the initialization process in Spring. If you have to initialize all beans and autowire/inject them there are at least two ways that I know of that will ensure this. I have only testet the second one but I belive both work the same.

If you are using @Bean you can reference by initMethod, like this.

@Configuration
public class BeanConfiguration {

  @Bean(initMethod="init")
  public BeanA beanA() {
    return new BeanA();
  }
}

public class BeanA {

  // method to be initialized after context is ready
  public void init() {
  }

} 

If you are using @Component you can annotate with @EventListener like this.

@Component
public class BeanB {

  @EventListener
  public void onApplicationEvent(ContextRefreshedEvent event) {
  }
}

In my case I have a legacy system where I am now taking use of IoC/DI where Spring Boot is the choosen framework. The old system brings many circular dependencies to the table and I therefore must use setter-dependency a lot. That gave me some headaches since I could not trust @PostConstruct since autowiring/injection by setter was not yet done. The order is constructor, @PostConstruct then autowired setters. I solved it with @EventListener annotation which wil run last and at the "same" time for all beans. The example shows implementation of InitializingBean aswell.

I have two classes (@Component) with dependency to each other. The classes looks the same for the purpose of this example displaying only one of them.

@Component
public class BeanA implements InitializingBean {
  private BeanB beanB;

  public BeanA() {
    log.debug("Created...");
  }

  @PostConstruct
  private void postConstruct() {
    log.debug("@PostConstruct");
  }

  @Autowired
  public void setBeanB(BeanB beanB) {
    log.debug("@Autowired beanB");
    this.beanB = beanB;
  }

  @Override
  public void afterPropertiesSet() throws Exception {
    log.debug("afterPropertiesSet()");
  }

  @EventListener
  public void onApplicationEvent(ContextRefreshedEvent event) {
    log.debug("@EventListener");
  } 
}

This is the log output showing the order of the calls when the container starts.

As you can see @EventListener is run last after everything is ready and configured.

Yes, there is a difference. Html.ActionLink generates an <a href=".."></a> tag whereas Url.Action returns only an url.

For example:

@Html.ActionLink("link text", "someaction", "somecontroller", new { id = "123" }, null)

generates:

<a href="/somecontroller/someaction/123">link text</a>

and Url.Action("someaction", "somecontroller", new { id = "123" }) generates:

/somecontroller/someaction/123

There is also Html.Action which executes a child controller action.

If you want some extra flexibility, you can also set the weights manually.

Say you have input of all ones:

import torch
import torch.nn as nn

input = torch.ones((8, 8))
print(input)

tensor([[1., 1., 1., 1., 1., 1., 1., 1.],
        [1., 1., 1., 1., 1., 1., 1., 1.],
        [1., 1., 1., 1., 1., 1., 1., 1.],
        [1., 1., 1., 1., 1., 1., 1., 1.],
        [1., 1., 1., 1., 1., 1., 1., 1.],
        [1., 1., 1., 1., 1., 1., 1., 1.],
        [1., 1., 1., 1., 1., 1., 1., 1.],
        [1., 1., 1., 1., 1., 1., 1., 1.]])

And you want to make a dense layer with no bias (so we can visualize):

d = nn.Linear(8, 8, bias=False)

Set all the weights to 0.5 (or anything else):

d.weight.data = torch.full((8, 8), 0.5)
print(d.weight.data)

The weights:

Out[14]: 
tensor([[0.5000, 0.5000, 0.5000, 0.5000, 0.5000, 0.5000, 0.5000, 0.5000],
        [0.5000, 0.5000, 0.5000, 0.5000, 0.5000, 0.5000, 0.5000, 0.5000],
        [0.5000, 0.5000, 0.5000, 0.5000, 0.5000, 0.5000, 0.5000, 0.5000],
        [0.5000, 0.5000, 0.5000, 0.5000, 0.5000, 0.5000, 0.5000, 0.5000],
        [0.5000, 0.5000, 0.5000, 0.5000, 0.5000, 0.5000, 0.5000, 0.5000],
        [0.5000, 0.5000, 0.5000, 0.5000, 0.5000, 0.5000, 0.5000, 0.5000],
        [0.5000, 0.5000, 0.5000, 0.5000, 0.5000, 0.5000, 0.5000, 0.5000],
        [0.5000, 0.5000, 0.5000, 0.5000, 0.5000, 0.5000, 0.5000, 0.5000]])

All your weights are now 0.5. Pass the data through:

d(input)

Out[13]: 
tensor([[4., 4., 4., 4., 4., 4., 4., 4.],
        [4., 4., 4., 4., 4., 4., 4., 4.],
        [4., 4., 4., 4., 4., 4., 4., 4.],
        [4., 4., 4., 4., 4., 4., 4., 4.],
        [4., 4., 4., 4., 4., 4., 4., 4.],
        [4., 4., 4., 4., 4., 4., 4., 4.],
        [4., 4., 4., 4., 4., 4., 4., 4.],
        [4., 4., 4., 4., 4., 4., 4., 4.]], grad_fn=<MmBackward>)

Remember that each neuron receives 8 inputs, all of which have weight 0.5 and value of 1 (and no bias), so it sums up to 4 for each.

If you are certain that you only need column A, then you can use an End function in VBA to get that result.

If all the cells A1:A100 are filled, then to select the next empty cell use:

Range("A1").End(xlDown).Offset(1, 0).Select

Here, End(xlDown) is the equivalent of selecting A1 and pressing Ctrl + Down Arrow.

If there are blank cells in A1:A100, then you need to start at the bottom and work your way up. You can do this by combining the use of Rows.Count and End(xlUp), like so:

Cells(Rows.Count, 1).End(xlUp).Offset(1, 0).Select

Going on even further, this can be generalized to selecting a range of cells, starting at a point of your choice (not just in column A). In the following code, assume you have values in cells C10:C100, with blank cells interspersed in between. You wish to select all the cells C10:C100, not knowing that the column ends at row 100, starting by manually selecting C10.

Range(Selection, Cells(Rows.Count, Selection.Column).End(xlUp)).Select

The above line is perhaps one of the more important lines to know as a VBA programmer, as it allows you to dynamically select ranges based on very few criteria, and not be bothered with blank cells in the middle.

The issue is fixed by adding repository url under distributionManagement tab in main pom.xml.

Jenkin maven goal : clean deploy -U -Dmaven.test.skip=true

<distributionManagement>
    <repository>
        <id>releases</id>
        <url>http://domain:port/content/repositories/releases</url>
    </repository>
    <snapshotRepository>

        <url>http://domain:port/content/repositories/snapshots</url>
    </snapshotRepository>
</distributionManagement>

Latest version of SpringBoot makes uploading multiple files very easy also. On the browser side you just need the standard HTML upload form, but with multiple input elements (one per file to upload, which is very important), all having the same element name (name="files" for the example below)

Then in your Spring @Controller class on the server all you need is something like this:

@RequestMapping(value = "/upload", method = RequestMethod.POST)
    public @ResponseBody ResponseEntity<?> upload(
        @RequestParam("files") MultipartFile[] uploadFiles) throws Exception     
{
    ...now loop over all uploadFiles in the array and do what you want
  return new ResponseEntity<>(HttpStatus.OK);
}

Those are the tricky parts. That is, knowing to create multiple input elements each named "files", and knowing to use a MultipartFile[] (array) as the request parameter are the tricky things to know, but it's just that simple. I won't get into how to process a MultipartFile entry, because there's plenty of docs on that already.

The EOF flag is only set after a read operation attempts to read past the end of the file. get() is returning the symbolic constant traits::eof() (which just happens to equal -1) because it reached the end of the file and could not read any more data, and only at that point will eof() be true. If you want to check for this condition, you can do something like the following:

int ch;
while ((ch = inf.get()) != EOF) {
    std::cout << static_cast<char>(ch) << "\n";
}

Try this it might solve your problem.

Css:

.item{padding-top:1px;}

.jobs .item:hover {
    background: #e1e1e1;
    border-top: 1px solid #d0d0d0;
    padding-top:0;
}

HTML:

<div class="jobs">
    <div class="item">
        content goes here
    </div>
</div>

See fiddle for output: http://jsfiddle.net/dLDNA/

Try this:

<div id="mainTable" style="width:100px; height:200px;"></div> 

$(document).ready(function() {
  $("#mainTable").width(100).height(200);
}) ;

easy way to do it: To get the actual user count:

$ADInfo = Get-ADGroup -Identity '<groupname>' -Properties Members
$AdInfo.Members.Count

and you get the count easily, it is pretty fast as well for 20k+ users too

Taken from: http://www.w3.org/Style/Examples/007/units:

The em is simply the font size. In an element with a 2in font, 1em thus means 2in. Expressing sizes, such as margins and paddings, in em means they are related to the font size, and if the user has a big font (e.g., on a big screen) or a small font (e.g., on a handheld device), the sizes will be in proportion. Declarations such as 'text-indent: 1.5em' and 'margin: 1em' are extremely common in CSS.

em is basically CSS property for font sizes.

Yeah.ios supports RGB valur to range between 0 and 1 only..its close Range [0,1]

I resolved this problem by navigating to C:\Python27\Scripts folder and then run file.py file instead of C:\Python27 folder

This is the solution that I came up with trying to solve this problem for myself in order to systematically produce \n's as separators. It writes using a list of strings where each string is one line of the file, however it seems that it may work for you as well. (Python 3.+)

#Takes a list of strings and prints it to a file.
def writeFile(file, strList):
    line = 0
    lines = []
    while line < len(strList):
        lines.append(cheekyNew(line) + strList[line])
        line += 1
    file = open(file, "w")
    file.writelines(lines)
    file.close()

#Returns "\n" if the int entered isn't zero, otherwise "".
def cheekyNew(line):
    if line != 0:
        return "\n"
    return ""

I let Eclipse do it for me when they are being used in an anonymous class, which is increasing due to my use of Google Collection API.

there is another way, if you are using a container like Tomcat :

String textPath = "http://localhost:8080/NameOfWebapp/resources/images/file.txt";

Try trimming the string to make sure there is no extra white space:

Cursor c = db.rawQuery("SELECT * FROM tbl1 WHERE TRIM(name) = '"+name.trim()+"'", null);

Also use c.moveToFirst() like @thinksteep mentioned.

This is a complete code for select statements.

SQLiteDatabase db = this.getReadableDatabase();
Cursor c = db.rawQuery("SELECT column1,column2,column3 FROM table ", null);
if (c.moveToFirst()){
    do {
        // Passing values 
        String column1 = c.getString(0);
        String column2 = c.getString(1);
        String column3 = c.getString(2); 
        // Do something Here with values
    } while(c.moveToNext());
}
c.close();
db.close();

You need to put the last() indexing on the nodelist result, rather than as part of the selection criteria. Try:

(//element[@name='D'])[last()]

<View 
   style={{
        flexDirection: 'row',
        padding: 10,
    }}
>
  <Text numberOfLines={5} style={{flex:1}}>
       This is a very long text that will overflow on a small device This is a very 
       long text that will overflow on a small deviceThis is a very long text that 
       will overflow on a small deviceThis is a very long text that will overflow 
       on a small device
  </Text>
</View>

How to Easily access LocalHost in Actual Android Device -> Connect your pc with the android device via USB

1. Go to Chrome inspection click 'f12' or Control+Shift+C

Chrome Inspection tool

2. Check the bottom of the chrome inspection tool.

3. Now go to settings in Remote Device Tab.

Remote Devices Tab

4. check on "Discover USB Device" option as well as check on "Port Forwarding" option.

5. Now Click on Add Rules, Enter Any Device Port e.g(4880) and in Local Address Enter the Actual Address of the local host in my case e.g (127.0.0.1:480)

6. After Adding the Rule go to your android studio -> inside your code URL(http://127.0.0.1:4880). Remember to change the port from 480 -> 4880.

7. Go to Remote Device Tab in Chrome and Click on your connected Device. Add New URL(127.0.0.1:4880) Inspect the Android Device Chrome Browser

Check your Actual Device Chrome Browser and start Debugging the code on Actual Android device.

You can use this code

ArrayList<TypeA> a = new ArrayList<TypeA>();
Object[] o = a.toArray();

Then if you want that to get that object back into TypeA just check it with instanceOf method.

Create a new Table With Different name and same columns, Primary Key and Foreign Key association and link this in your Insert statement of code. For E.g : For EMPLOYEE, replace with EMPLOYEES.

CREATE TABLE EMPLOYEES(

    EmpId        INT NOT NULL IDENTITY(1,1), 
    F_Name       VARCHAR(20) ,
    L_Name       VARCHAR(20) ,
    DOB          DATE ,
    DOJ          DATE ,
    PRIMARY KEY (EmpId),
    DeptId int FOREIGN KEY REFERENCES DEPARTMENT(DeptId),
    DesgId int FOREIGN KEY REFERENCES DESIGNATION(DesgId),
    AddId int FOREIGN KEY REFERENCES ADDRESS(AddId)   
) 

However, you have to either delete the existing EMPLOYEE Table or do some adjustment according to your requirement.

UPDATE dummy SET myfield=1 WHERE id>1;

From the session_destroy() page in the PHP manual:

<?php
// Initialize the session.
// If you are using session_name("something"), don't forget it now!
session_start();

// Unset all of the session variables.
$_SESSION = array();

// If it's desired to kill the session, also delete the session cookie.
// Note: This will destroy the session, and not just the session data!
if (ini_get("session.use_cookies")) {
    $params = session_get_cookie_params();
    setcookie(session_name(), '', time() - 42000,
        $params["path"], $params["domain"],
        $params["secure"], $params["httponly"]
    );
}

// Finally, destroy the session.
session_destroy();
?>

After some research, I have the following code which works very well for me. It basically prints both stdout and stderr in real time.

stdout_result = 1
stderr_result = 1


def stdout_thread(pipe):
    global stdout_result
    while True:
        out = pipe.stdout.read(1)
        stdout_result = pipe.poll()
        if out == '' and stdout_result is not None:
            break

        if out != '':
            sys.stdout.write(out)
            sys.stdout.flush()


def stderr_thread(pipe):
    global stderr_result
    while True:
        err = pipe.stderr.read(1)
        stderr_result = pipe.poll()
        if err == '' and stderr_result is not None:
            break

        if err != '':
            sys.stdout.write(err)
            sys.stdout.flush()


def exec_command(command, cwd=None):
    if cwd is not None:
        print '[' + ' '.join(command) + '] in ' + cwd
    else:
        print '[' + ' '.join(command) + ']'

    p = subprocess.Popen(
        command, stdout=subprocess.PIPE, stderr=subprocess.PIPE, cwd=cwd
    )

    out_thread = threading.Thread(name='stdout_thread', target=stdout_thread, args=(p,))
    err_thread = threading.Thread(name='stderr_thread', target=stderr_thread, args=(p,))

    err_thread.start()
    out_thread.start()

    out_thread.join()
    err_thread.join()

    return stdout_result + stderr_result

The "if" expression tests for truthiness, while the double-equal tests for type-independent equivalency. A string is always truthy, as others here have pointed out. If the double-equal were testing both of its operands for truthiness and then comparing the results, then you'd get the outcome you were intuitively assuming, i.e. ("0" == true) === true. As Doug Crockford says in his excellent JavaScript: the Good Parts, "the rules by which [== coerces the types of its operands] are complicated and unmemorable.... The lack of transitivity is alarming." It suffices to say that one of the operands is type-coerced to match the other, and that "0" ends up being interpreted as a numeric zero, which is in turn equivalent to false when coerced to boolean (or false is equivalent to zero when coerced to a number).

You can use ThrowIfCancellationRequested without handling the exception!

The use of ThrowIfCancellationRequested is meant to be used from within a Task (not a Thread). When used within a Task, you do not have to handle the exception yourself (and get the Unhandled Exception error). It will result in leaving the Task, and the Task.IsCancelled property will be True. No exception handling needed.

In your specific case, change the Thread to a Task.

Task t = null;
try
{
    t = Task.Run(() => Work(cancelSource.Token), cancelSource.Token);
}

if (t.IsCancelled)
{
    Console.WriteLine("Canceled!");
}

Try this:

jQuery('.delbtn').on('click', function() {
    var $row = jQuery(this).closest('tr');
    var $columns = $row.find('td');

    $columns.addClass('row-highlight');
    var values = "";

    jQuery.each($columns, function(i, item) {
        values = values + 'td' + (i + 1) + ':' + item.innerHTML + '<br/>';
        alert(values);
    });
    console.log(values);
});

Yes, of course there exists Math.max.apply(null,[23,45,67,-45]) and the result is to return 67.

Using Classes in Node -

Here we are requiring the ReadWrite module and calling a makeObject(), which returns the object of the ReadWrite class. Which we are using to call the methods. index.js

const ReadWrite = require('./ReadWrite').makeObject();
const express = require('express');
const app = express();

class Start {
  constructor() {
    const server = app.listen(8081),
     host = server.address().address,
     port = server.address().port
    console.log("Example app listening at http://%s:%s", host, port);
    console.log('Running');

  }

  async route(req, res, next) {
    const result = await ReadWrite.readWrite();
    res.send(result);
  }
}

const obj1 = new Start();
app.get('/', obj1.route);
module.exports = Start;

ReadWrite.js

Here we making a makeObject method, which makes sure that a object is returned, only if a object is not available.

class ReadWrite {
    constructor() {
        console.log('Read Write'); 
        this.x;   
    }
    static makeObject() {        
        if (!this.x) {
            this.x = new ReadWrite();
        }
        return this.x;
    }
    read(){
    return "read"
    }

    write(){
        return "write"
    }


    async readWrite() {
        try {
            const obj = ReadWrite.makeObject();
            const result = await Promise.all([ obj.read(), obj.write()])
            console.log(result);
            check();
            return result
        }
        catch(err) {
            console.log(err);

        }
    }
}
module.exports = ReadWrite;

Bootstrap 3

Yes, it's possible. This "off-canvas" example should help to get you started.

https://codeply.com/p/esYgHWB2zJ

Basically you need to wrap the layout in an outer div, and use media queries to toggle the layout on smaller screens.

/* collapsed sidebar styles */
@media screen and (max-width: 767px) {

Create a responsive navbar sidebar "drawer" in Bootstrap 4?

I found the same situation and the approach which I took was as follows:

1. Execute SHOW CREATE TABLE <table name to clone> : This will give you the Create Table syntax for the table which you want to clone
2. Run the CREATE TABLE query by changing the table name to clone the table.

This will create exact replica of the table which you want to clone along with indexes. The only thing which you then need is to rename the indexes (if required).

Assuming I understand what you mean:

1. If your UserControl is in a library you can add this to you Toolbox using

   Toolbox -> right click -> Choose Items -> Browse

   Select your assembly with the UserControl.

2. If the UserControl is part of your project you only need to build the entire solution. After that, your UserControl should appear in the toolbox.

In general, it is not possible to add a Control from Solution Explorer, only from the Toolbox.

The problem

I literally quote Saeed Neamati (https://stackoverflow.com/a/6587434/760777):

In your request header, you have sent Content-Type: text/html which means that you'd like to interpret the response as HTML. Now if even server send you PDF files, your browser tries to understand it as HTML.

The solution

Send the bloody correct header. Send the correct mime type of the file. Period!

How?

Aaah. That totally depends on what you are doing (OS, language).

My problem was with a dynamically created download link in javascript. The link is for downloading an mp3 file. An mp3 file is not a document, neither is a pdf, a zip file, a flac file and the list goes on.

So I created the link like this:

<form method="get" action="test.mp3"> 
  <a href="#" onclick="this.closest(form).submit();return false;" target="_blank">
    <span class="material-icons">
      download
    </span>
  </a>
</form>

and I changed it to this:

<form method="get" action="test.mp3" enctype="multipart/form-data"> 
  <a href="#" onclick="this.closest(form).submit();return false;" target="_blank">
    <span class="material-icons">
      download
    </span>
  </a>
</form>

Problem solved. Adding an extra attribute to the form tag solved it. But there is no generic solution. There are many different scenario's. When you send a file from the server (you created it dynamically with a language like CX#, Java, PHP), you have to send the correct header(s) with it.

Side note: And be careful not to send anything (text!) before you send your header(s).

I was already adding something to the background so , This thing worked for me:

   android:backgroundTint="@android:color/transparent"

(Android Studio 3.4.1)

EDIT: only works on android api level 21 and above. for compatibility, use this instead

   android:background="@android:color/transparent"

Fix for iPhone X/XS screen rotation issue

On iPhone X/XS, a screen rotation will cause the header bar height to use an incorrect value, because the calculation of safe-area-inset-* was not reflecting the new values in time for UI refresh. This bug exists in UIWebView even in the latest iOS 12. A workaround is inserting a 1px top margin and then quickly reversing it, which will trigger safe-area-inset-* to be re-calculated immediately. A somewhat ugly fix but it works if you have to stay with UIWebView for one reason or another.

window.addEventListener("orientationchange", function() {_x000D_
    var originalMarginTop = document.body.style.marginTop;_x000D_
    document.body.style.marginTop = "1px";_x000D_
    setTimeout(function () {_x000D_
        document.body.style.marginTop = originalMarginTop;_x000D_
    }, 100);_x000D_
}, false);

The purpose of the code is to cause the document.body.style.marginTop to change slightly and then reverse it. It doesn't necessarily have to be "1px". You can pick a value that doesn't cause your UI to flicker but achieves its purpose.

alt and title are for different things, as already mentioned. While the title attribute will provide a tooltip, alt is also an important attribute, since it specifies text to be displayed if the image can't be displayed. (And in some browsers, such as firefox, you'll also see this text while the image loads)

Another point that I feel should be made is that the alt attribute is required to validate as an XHTML document, whereas the title attribute is just an "extra option," as it were.

I do not think a Git commit can record an intention like “stop tracking this file, but do not delete it”.

Enacting such an intention will require intervention outside Git in any repositories that merge (or rebase onto) a commit that deletes the file.

Save a Copy, Apply Deletion, Restore

Probably the easiest thing to do is to tell your downstream users to save a copy of the file, pull your deletion, then restore the file. If they are pulling via rebase and are ‘carrying’ modifications to the file, they will get conflicts. To resolve such conflicts, use git rm foo.conf && git rebase --continue (if the conflicting commit has changes besides those to the removed file) or git rebase --skip (if the conflicting commit has only changed to the removed file).

Restore File as Untracked After Pulling a Commit That Deletes It

If they have already pulled your deletion commit, they can still recover the previous version of the file with git show:

git show @{1}:foo.conf >foo.conf

Or with git checkout (per comment by William Pursell; but remember to re-remove it from the index!):

git checkout @{1} -- foo.conf && git rm --cached foo.conf

If they have taken other actions since pulling your deletion (or they are pulling with rebase into a detached HEAD), they may need something other than @{1}. They could use git log -g to find the commit just before they pulled your deletion.

In a comment, you mention that the file you want to “untrack, but keep” is some kind of configuration file that is required for running the software (directly out of a repository).

Keep File as a ‘Default’ and Manually/Automatically Activate It

If it is not completely unacceptable to continue to maintain the configuration file's content in the repository, you might be able to rename the tracked file from (e.g.) foo.conf to foo.conf.default and then instruct your users to cp foo.conf.default foo.conf after applying the rename commit. Or, if the users already use some existing part of the repository (e.g. a script or some other program configured by content in the repository (e.g. Makefile or similar)) to launch/deploy your software, you could incorporate a defaulting mechanism into the launch/deploy process:

test -f foo.conf || test -f foo.conf.default &&
    cp foo.conf.default foo.conf

With such a defaulting mechanism in place, users should be able to pull a commit that renames foo.conf to foo.conf.default without having to do any extra work. Also, you avoid having to manually copy a configuration file if you make additional installations/repositories in the future.

Rewriting History Requires Manual Intervention Anyway…

If it is unacceptable to maintain the content in the repository then you will likely want to completely eradicate it from history with something like git filter-branch --index-filter …. This amounts to rewriting history, which will require manual intervention for each branch/repository (see “Recovering From Upstream Rebase” section in the git rebase manpage). The special treatment required for your configuration file would be just another step that one must perform while recovering from the rewrite:

1. Save a copy of the configuration file.
2. Recover from the rewrite.
3. Restore the configuration file.

Ignore It to Prevent Recurrence

Whatever method you use, you will probably want to include the configuration filename in a .gitignore file in the repository so that no one can inadvertently git add foo.conf again (it is possible, but requires -f/--force). If you have more than one configuration file, you might consider ‘moving’ them all into a single directory and ignoring the whole thing (by ‘moving’ I mean changing where the program expects to find its configuration files, and getting the users (or the launch/deploy mechanism) to copy/move the files to to their new location; you obviously would not want to git mv a file into a directory that you will be ignoring).

If you've tried modifying etc/hosts and adding java.rmi.server.hostname property as well but still registry is being bind to 127.0.0.1

the issue for me was resolved after explicitly setting System property through code though the same property wasn't picked from jvm args

SELECT DATE('2012-11-12 00:00:00');

returns

2012-11-12

In Toad I use this works:

declare 
    num number;
begin 
    ---- use 'select into' works 
    --select 123 into num from dual;

    ---- also can use :=
    num := 123;
    dbms_output.Put_line(num);
end;

Then the value will be print to DBMS Output Window.

You need to add two new file one is index.html, copy and paste the below code and other is imageup.php which will upload your image

 <form action="imageup.php" method="post" enctype="multipart/form-data">
 <input type="file" name="banner" >
 <input type="submit" value="submit">
 </form>

 imageup.php
 <?php
 $banner=$_FILES['banner']['name']; 
 $expbanner=explode('.',$banner);
 $bannerexptype=$expbanner[1];
 date_default_timezone_set('Australia/Melbourne');
 $date = date('m/d/Yh:i:sa', time());
 $rand=rand(10000,99999);
 $encname=$date.$rand;
 $bannername=md5($encname).'.'.$bannerexptype;
 $bannerpath="uploads/banners/".$bannername;
 move_uploaded_file($_FILES["banner"]["tmp_name"],$bannerpath);
 ?>

The above code will upload your image with encrypted name

Use

getActivity().getApplicationContext()

to obtain the context in any fragment

$('.input').on('focus', function(){
    $(this).val('');
});

$('[type="submit"]').on('click', function(){
    $('.input').val('');
});

There are definitely different ways to do this depending on your needs.

One way I use a UI-updating thread (that's not the main UI thread) is to have the thread start a loop where the entire logical processing loop is invoked onto the UI thread.

Example:

public SomeFunction()
{
    bool working = true;
    Thread t = new Thread(() =>
    {
        // Don't put the working bool in here, otherwise it will 
        // belong to the new thread and not the main UI thread.
        while (working)
        {
            Application.Current.Dispatcher.Invoke(() =>
            {
                // Put your entire logic code in here.
                // All of this code will process on the main UI thread because
                //  of the Invoke.
                // By doing it this way, you don't have to worry about Invoking individual
                //  elements as they are needed.
            });
        }
    });
}

With this, code executes entirely on main UI thread. This can be a pro for amateur programmers that have difficulty wrapping their heads around cross-threaded operations. However, it can easily become a con with more complex UIs (especially if performing animations). Really, this is only to fake a system of updating the UI and then returning to handle any events that have fired in lieu of efficient cross-threading operations.

Answer os Crisalin is almost perfect. Just improved the performance to avoid create new RegExp on each run.

var normalizeConversions = [
    { regex: new RegExp('ä|æ|?', 'g'), clean: 'ae' },

Usage:

function(str){
    normalizeConversions.forEach(function(normalizeEntry){
        str = str.replace(normalizeEntry.regex, normalizeEntry.clean);
    });
    return str;
};

Unless you're trying to upload the file using ajax, just submit the form to /upload/image.

<form enctype="multipart/form-data" action="/upload/image" method="post">
    <input id="image-file" type="file" />
</form>

If you do want to upload the image in the background (e.g. without submitting the whole form), you can use ajax:

• Asynchronous file upload (AJAX file upload) using jsp and javascript
• jQuery Ajax File Upload
• Ajax using file upload

I have patched the behaviour of my eclipse startup shortcut in the properties dialogue

from

"E:\Program Files\eclipse\eclipse.exe"

to

"E:\Program Files\eclipse\eclipse.exe" -vm "E:\Program Files\Java\jdk1.6.0_30\bin"

as described in the Eclipse documentation

It is a patch only, as it depends on the shortcut to fix things...

The alternative is to set the parameter permanently in the eclipse initialisation file.

If you're using org.codehaus.jackson, this has been possible since 1.6. You can convert a JsonNode to a POJO with ObjectMapper#readValue: http://jackson.codehaus.org/1.9.4/javadoc/org/codehaus/jackson/map/ObjectMapper.html#readValue(org.codehaus.jackson.JsonNode, java.lang.Class)

    ObjectMapper mapper = new ObjectMapper();
    JsonParser jsonParser = mapper.getJsonFactory().createJsonParser("{\"foo\":\"bar\"}");
    JsonNode tree = jsonParser.readValueAsTree();
    // Do stuff to the tree
    mapper.readValue(tree, Foo.class);

I had the same issue using Windows, got if fixed by opening it in Notepad++ and changing the encoding from "UCS-2 LE BOM" to "UTF-8".

I believe you're looking for the @filename syntax, e.g.:

strip new lines

curl --data "@/path/to/filename" http://...

keep new lines

curl --data-binary "@/path/to/filename" http://...

curl will strip all newlines from the file. If you want to send the file with newlines intact, use --data-binary in place of --data

JObject implements IDictionary<string, JToken>, so you can use:

IDictionary<string, JToken> dictionary = x;
if (dictionary.ContainsKey("error_msg"))

... or you could use TryGetValue. It implements both methods using explicit interface implementation, so you can't use them without first converting to IDictionary<string, JToken> though.

you can use ESCAPE like given example below

The '_' wild card character is used to match exactly one character, while '%' is used to match zero or more occurrences of any characters. These characters can be escaped in SQL.

SELECT name FROM emp WHERE id LIKE '%/_%' ESCAPE '/';

The same works inside PL/SQL:

 if( id like '%/_%' ESCAPE '/' )

This applies only to like patterns, for example in an insert there is no need to escape _ or %, they are used as plain characters anyhow. In arbitrary strings only ' needs to be escaped by ''.

Use the object syntax.

v-bind:class="{'fa-checkbox-marked': content['cravings'],  'fa-checkbox-blank-outline': !content['cravings']}"

When the object gets more complicated, extract it into a method.

v-bind:class="getClass()"

methods:{
    getClass(){
        return {
            'fa-checkbox-marked': this.content['cravings'],  
            'fa-checkbox-blank-outline': !this.content['cravings']}
    }
}

Finally, you could make this work for any content property like this.

v-bind:class="getClass('cravings')"

methods:{
  getClass(property){
    return {
      'fa-checkbox-marked': this.content[property],
      'fa-checkbox-blank-outline': !this.content[property]
    }
  }
}

Yep,there is a way you could do it

1. Right click->Inspect->sources(tab)

2. Towards Your right there will be a "pause script execution button"

I hope it helps!Peace

You have your storyboard set up to expect an outlet called tableView but the actual outlet name is myTableView.

If you delete the connection in the storyboard and reconnect to the right variable name, it should fix the problem.

sp_spaceused gives you the size of all the indexes combined.

If you want the size of each index for a table, use one of these two queries:

SELECT
    i.name                  AS IndexName,
    SUM(s.used_page_count) * 8   AS IndexSizeKB
FROM sys.dm_db_partition_stats  AS s 
JOIN sys.indexes                AS i
ON s.[object_id] = i.[object_id] AND s.index_id = i.index_id
WHERE s.[object_id] = object_id('dbo.TableName')
GROUP BY i.name
ORDER BY i.name

SELECT
    i.name              AS IndexName,
    SUM(page_count * 8) AS IndexSizeKB
FROM sys.dm_db_index_physical_stats(
    db_id(), object_id('dbo.TableName'), NULL, NULL, 'DETAILED') AS s
JOIN sys.indexes AS i
ON s.[object_id] = i.[object_id] AND s.index_id = i.index_id
GROUP BY i.name
ORDER BY i.name

The results are usually slightly different but within 1%.

While the above answers are valid, and I agree with readability being important, there are 2 further points to consider:

1. In C#6, you can have expression-bodied methods.

This makes it particularly concise to use the ternary:

string GetDrink(DayOfWeek day) 
   => day == DayOfWeek.Friday
      ? "Beer" : "Tea";

2. Behaviour differs when it comes to implicit type conversion.

If you have types T1 and T2 that can both be implicitly converted to T, then the below does not work:

T GetT() => true ? new T1() : new T2();

(because the compiler tries to determine the type of the ternary expression, and there is no conversion between T1 and T2.)

On the other hand, the if/else version below does work:

T GetT()
{
   if (true) return new T1();
   return new T2();
}

because T1 is converted to T and so is T2

You can use

First, brightness(0) makes all image black, except transparent parts, which remain transparent.

Then, invert(1) makes the black parts white.

ffmpeg logs to stderr, and can log to a file with a different log-level from stderr. The -report command-line option doesn't give you control of the log file name or the log level, so setting the environment variable is preferable.

(-v is a synonym for -loglevel. Run ffmpeg -v help to see the levels. Run ffmpeg -h full | less to see EVERYTHING. Or consult the online docs, or their wiki pages like the h.264 encode guide).

of=out.mkv
FFREPORT="level=32:file=$of.log" ffmpeg -v verbose   -i src.mp4 -c:a copy -preset slower -c:v libx264 -crf 21 "$of"

That will trancode src.mp4 with x264, and set the log level for stderr to "verbose", and the log level for out.mkv.log to "status".

(AV_LOG_WARNING=24, AV_LOG_INFO=32, AV_LOG_VERBOSE=40, etc.). Support for this was added 2 years ago, so you need a non-ancient version of ffmpeg. (Always a good idea anyway, for security / bugfixes and speedups)

A few codecs, like -c:v libx265, write directly to stderr instead of using ffmpeg's logging infrastructure. So their log messages don't end up in the report file. I assume this is a bug / TODO-list item.

To log stderr, while still seeing it in a terminal, you can use tee(1).

If you use a log level that includes status line updates (the default -v info, or higher), they will be included in the log file, separated with ^M (carriage return aka \r). There's no log level that includes encoder stats (like SSIM) but not status-line updates, so the best option is probably to filter that stream.

If don't want to filter (e.g. so the fps / bitrate at each status-update interval is there in the file), you can use less -r to pass them through directly to your terminal so you can view the files cleanly. If you have .enc logs from several encodes that you want to flip through, less -r ++G *.enc works great. (++G means start at the end of the file, for all files). With single-key key bindings like . and , for next file and previous file, you can flip through some log files very nicely. (the default bindings are :n and :p).

If you do want to filter, sed 's/.*\r//' works perfectly for ffmpeg output. (In the general case, you need something like vt100.py, but not for just carriage returns). There are (at least) two ways to do this with tee + sed: tee to /dev/tty and pipe tee's output into sed, or use a process substitution to tee into a pipe to sed.

# pass stdout and stderr through to the terminal, 
## and log a filtered version to a file (with only the last status-line update).

of="$1-x265.mkv"
ffmpeg -v info -i "$1" -c:a copy -c:v libx265 ... "$of" |&    # pipe stdout and stderr
   tee /dev/tty | sed 's/.*\r//' >> "$of.enc"

## or with process substitution where tee's arg will be something like /dev/fd/123

ffmpeg -v info -i "$1" -c:a copy -c:v libx265 ... "$of" |&
  tee >(sed 's/.*\r//' >> "$of.enc")

For testing a few different encode parameters, you can make a function like this one that I used recently to test some stuff. I had it all on one line so I could easily up-arrow and edit it, but I'll un-obfuscate it here. (That's why there are ;s at the end of each line)

ffenc-testclip(){
  # v should be set by the caller, to a vertical resolution.  We scale to WxH, where W is a multiple of 8 (-vf scale=-8:$v)
  db=0;   # convenient to use shell vars to encode settings that you want to include in the filename and the ffmpeg cmdline
  [email protected].${v}p.x265$pre.mkv; 
  [[ -e "$of.enc" ]]&&echo "$of.enc exists"&&return;   # early-out if the file exists

  # encode 25 seconds starting at 21m15s (or the keyframe before that)
  nice -14 ffmpeg -ss $((21*60+15))  -i src.mp4 -t 25  -map 0 -metadata title= -color_primaries bt709 -color_trc bt709 -colorspace bt709 -sws_flags lanczos+print_info -c:a copy -c:v libx265 -b:v 1500k -vf scale=-8:$v  -preset $pre -ssim 1 -x265-params ssim=1:cu-stats=1:deblock=$db:aq-mode=1:lookahead-slices=0 "$of" |&
   tee /dev/tty | sed 's/.*\r//' >> "$of.enc";
}

# and use it with nested loops like this.
for pre in fast slow;  do for v in  360 480 648 792;do  ffenc-testclip ;done;done

less -r ++G *.enc       # -r is useful if you didn't use sed

Note that it tests for existence of the output video file to avoid spewing extra garbage into the log file if it already exists. Even so, I used and append (>>) redirect.

It would be "cleaner" to write a shell function that took args instead of looking at shell variables, but this was convenient and easy to write for my own use. That's also why I saved space by not properly quoting all my variable expansions. ($v instead of "$v")

First day of week (Monday):

SELECT TO_DATE(to_char(sysdate,'YYYY')||'0101','YYYYMMDD') + 7 * to_number(to_char(sysdate,'WW')-1)-1 first_day_week FROM dual;

Last day of week (Sunday):

SELECT TO_DATE(to_char(sysdate,'YYYY')||'0101','YYYYMMDD') + 7 * to_number(to_char(sysdate,'WW')-1)+5 last_day_week FROM dual;

Substituting your date or date field in these formulas will work for you!

Have a look at CSS and HTML in depth you will figure this out. It just floating the boxes left and right and those boxes need to be inside a same div. http://www.w3schools.com/html/html_layout.asp might be a good resource.

If using RamdaJS is an option, this can be achieved in one line: R.transpose(myArray)

This works for me, even when run inside an included PHP file, and you want the filename of the current php file running:

$currentPage= $_SERVER["SCRIPT_NAME"];
$currentPage = substr($currentPage, 1);
echo $currentPage;

Result:

Another possible cause of this error is that you have forgotten to add the libraries that are already in the /WEBINF/lib folder to the build path (e.g. when importing a .war-file and not checking the libraries when asked in the wizard). Just happened to me.

var pattern = /[0-9!"£$%^&*()_+-=]/;

This tries to avoid some scenarios, just in case:

Overflowing any buffers the original string might get passed to. Slowness or oddities caused by denormal numbers like 1E-323. Passing Infinity when a finite number is expected (try 1E309 or -1E309).

Easiest method: Alt+Enter on

private static final long serialVersionUID = ;

IntelliJ will underline the space after the =. put your cursor on it and hit alt+Enter (Option+Enter on Mac). You'll get a popover that says "Randomly Change serialVersionUID Initializer". Just hit enter, and it'll populate that space with a random long.

The easiest would be using a foreach:

foreach(GridViewRow row in GridView2.Rows)
{
    // here you'll get all rows with RowType=DataRow
    // others like Header are omitted in a foreach
}

Edit: According to your edits, you are accessing the column incorrectly, you should start with 0:

foreach(GridViewRow row in GridView2.Rows)
{
    for(int i = 0; i < GridView2.Columns.Count; i++)
    {
        String header = GridView2.Columns[i].HeaderText;
        String cellText = row.Cells[i].Text;
    }
}

You don't need a library to do this. You can do it with Java itself.

Chris Campbell has an excellent and detailed write-up on scaling images - see this article.

Chet Haase and Romain Guy also have a detailed and very informative write-up of image scaling in their book, Filthy Rich Clients.

Get the position of the first space:

int space1 = theString.IndexOf(' ');

The the position of the next space after that:

int space2 = theString.IndexOf(' ', space1 + 1);

Get the part of the string up to the second space:

string firstPart = theString.Substring(0, space2);

The above code put togehter into a one-liner:

string firstPart = theString.Substring(0, theString.IndexOf(' ', theString.IndexOf(' ') + 1));

Updating the ulimit worked for my Kosaraju's SCC implementation by fixing the segfault on both Python (Python segfault.. who knew!) and C++ implementations.

There are a lot of very nice answers on this page and I googled for some more, but none of the answers ticked all the checkboxes on my wish list:

• CSS only, no Javascript
• Stick to Tom Kenny's Best Design Practices
• Layout like the other answers
• Each step has a name and a number
• Responsive layout: font size independent
• Fluid layout: the list and its items scale with the available width
• The names and numbers are centered in their block
• The "done" color goes up to and including the active item, but not past it.
• The active item should stand out graphically

So I mixed the code of several examples, fixed the things that I needed and here is the result:

I used the following CSS and HTML:

        <span class="step"><span>4</span></span>_x000D_
    </li>_x000D_
</ol>

As can be seen in the example above, there are now two list item classes to take note of: active and done. Use class="active" for the current step, use class="done" for all steps before it.

Also note the data-steps="4" in the ol tag; set this to the total number of steps to apply the correct size to all list items.

Feel free to play around with the JSFiddle. Enjoy!

You'd need to override the negative margins from the .row in large screens either directly or with a custom class

@media (min-width: 768px){
    .row {
        margin-right: 0;
        margin-left: 0;
    }
}

Updated fiddle

I use this approach:

var myNamespace = {}
myNamespace._construct = function()
{
    var staticVariable = "This is available to all functions created here"

    function MyClass()
    {
       // Depending on the class, we may build all the classes here
       this.publicMethod = function()
       {
          //Do stuff
       }
    }

    // Alternatively, we may use a prototype.
    MyClass.prototype.altPublicMethod = function()
    {
        //Do stuff
    }

    function privateStuff()
    {
    }

    function publicStuff()
    {
       // Code that may call other public and private functions
    }

    // List of things to place publically
    this.publicStuff = publicStuff
    this.MyClass = MyClass
}
myNamespace._construct()

// The following may or may not be in another file
myNamespace.subName = {}
myNamespace.subName._construct = function()
{
   // Build namespace
}
myNamespace.subName._construct()

External code can then be:

var myClass = new myNamespace.MyClass();
var myOtherClass = new myNamepace.subName.SomeOtherClass();
myNamespace.subName.publicOtherStuff(someParameter);

function Animal(type) {
    if (type == "cat") {
        this.__proto__ = Cat.prototype;
    } else if (type == "dog") {
        this.__proto__ = Dog.prototype;
    } else if (type == "fish") {
        this.__proto__ = Fish.prototype;
    }
}
Animal.prototype.say = function() {
    alert("This animal can't speak!");
}

function Cat() {
    // init cat
}
Cat.prototype = new Animal();
Cat.prototype.say = function() {
    alert("Meow!");
}

function Dog() {
    // init dog
}
Dog.prototype = new Animal();
Dog.prototype.say = function() {
    alert("Bark!");
}

function Fish() {
    // init fish
}
Fish.prototype = new Animal();

var newAnimal = new Animal("dog");
newAnimal.say();

This isn't guaranteed to work as __proto__ isn't a standard variable, but it works at least in Firefox and Safari.

If you don't understand how it works, read about the prototype chain.

I had also found this error but I have solved this problem by easy steps. If you want to solve this problem follow these steps:

Step 1: First start code block

Step 2: Go to menu bar and click on the Setting menu

Step 3: After that click on the Compiler option

Step 4: Now, a pop up window will be opened. In this window, select "GNU GCC COMPILER"

Step 5: Now go to the toolchain executables tab and select the compiler installation directory like (C:\Program Files (x86)\CodeBlocks\MinGW\bin)

Step 6: Click on the Ok.

Now you can remove this error by follow these steps. Sometimes you don't need to select bin folder. You need to select only (C:\Program Files (x86)\CodeBlocks\MinGW) this path but some system doesn't work this path. That's why you have to select path from C:/ to bin folder.

Thank you.

For me when that usually starts happening, I have to remote desktop into the service and at the minimum restart IIS. It usually starts popping up right after I deploy code. On a few rare occasions I have had to restart the SQL services and IIS. I wrote a batch script to take a param (1 or 2) and have it setup to either do a restart of IIS ( i.e. 1), or go full nuclear (i.e. 2).

RegexBuddy is telling me if you want to include it at the beginning, this is the correct syntax:

"(?i)\\b(\\w+)\\b(\\s+\\1)+\\b"

To capitalize first word only:

foo='one two three'
foo="${foo^}"
echo $foo

One two three

To capitalize every word in the variable:

foo="one two three"
foo=( $foo ) # without quotes
foo="${foo[@]^}"
echo $foo

One Two Three

(works in bash 4+)

You could use list comprehension:

with open("names", "r") as f:
    names_list = [line.strip() for line in f if line.strip()]

Updated: Removed unnecessary readlines().

To avoid calling line.strip() twice, you can use a generator:

names_list = [l for l in (line.strip() for line in f) if l]

OK, I've worked it out! It involves changing the CSS slightly and adding some JS.

Using jQuery to make it easy:

$(document).ready(function() {
    $('.hover').on('touchstart touchend', function(e) {
        e.preventDefault();
        $(this).toggleClass('hover_effect');
    });
});

In english: when you start or end a touch, turn the class hover_effect on or off.

Then, in your HTML, add a class hover to anything you want this to work with. In your CSS, replace any instance of:

element:hover {
    rule:properties;
}

with

element:hover, element.hover_effect {
    rule:properties;
}

And just for added usefulness, add this to your CSS as well:

.hover {
-webkit-user-select: none;
-webkit-touch-callout: none;        
}

To stop the browser asking you to copy/save/select the image or whatever.

Easy!

You answered this in the way you wrote the question - use 'define'. but once set, you can't change a define.

Alternatively, there are tricks with a constant in a class, such as class::constant that you can use. You can also make them variable by declaring static properties to the class, with functions to set the static property if you want to change it.

Find your config.inc.php file under the phpMyAdmin installation directory and update the line that looks like
this:

... to this:

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

Some practical uses for the [Serializable] attribute:

• Saving object state using binary serialisation; you can very easily 'save' entire object instances in your application to a file or network stream and then recreate them by deserialising - check out the BinaryFormatter class in System.Runtime.Serialization.Formatters.Binary
• Writing classes whose object instances can be stored on the clipboard using Clipboard.SetData() - nonserialisable classes cannot be placed on the clipboard.
• Writing classes which are compatible with .NET Remoting; generally, any class instance you pass between application domains (except those which extend from MarshalByRefObject) must be serialisable.

These are the most common usage cases that I have come across.

js> s = "http://www.example.com/string with + and ? and & and spaces";
http://www.example.com/string with + and ? and & and spaces
js> encodeURI(s)
http://www.example.com/string%20with%20+%20and%20?%20and%20&%20and%20spaces
js> encodeURIComponent(s)
http%3A%2F%2Fwww.example.com%2Fstring%20with%20%2B%20and%20%3F%20and%20%26%20and%20spaces

Looks like encodeURI produces a "safe" URI by encoding spaces and some other (e.g. nonprintable) characters, whereas encodeURIComponent additionally encodes the colon and slash and plus characters, and is meant to be used in query strings. The encoding of + and ? and & is of particular importance here, as these are special chars in query strings.

The following can be used to retrieve JSESSIONID:

function getJSessionId(){
    var jsId = document.cookie.match(/JSESSIONID=[^;]+/);
    if(jsId != null) {
        if (jsId instanceof Array)
            jsId = jsId[0].substring(11);
        else
            jsId = jsId.substring(11);
    }
    return jsId;
}

There are three levels at which a newline could be inserted in a variable.
Well ..., technically four, but the first two are just two ways to write the newline in code.

1.1. At creation.

The most basic is to create the variable with the newlines already.
We write the variable value in code with the newlines already inserted.

$ var="a
> b
> c"
$ echo "$var"
a
b
c

Or, inside an script code:

var="a
b
c"

Yes, that means writing Enter where needed in the code.

1.2. Create using shell quoting.

The sequence $' is an special shell expansion in bash and zsh.

var=$'a\nb\nc'

The line is parsed by the shell and expanded to « var="anewlinebnewlinec" », which is exactly what we want the variable var to be.
That will not work on older shells.

2. Using shell expansions.

It is basically a command expansion with several commands:

1. echo -e

   var="$( echo -e "a\nb\nc" )"
   

2. The bash and zsh printf '%b'

   var="$( printf '%b' "a\nb\nc" )"
   

3. The bash printf -v

   printf -v var '%b' "a\nb\nc"
   

4. Plain simple printf (works on most shells):

   var="$( printf 'a\nb\nc' )"
   

3. Using shell execution.

All the commands listed in the second option could be used to expand the value of a var, if that var contains special characters.
So, all we need to do is get those values inside the var and execute some command to show:

var="a\nb\nc"                 # var will contain the characters \n not a newline.

echo -e "$var"                # use echo.
printf "%b" "$var"            # use bash %b in printf.
printf "$var"                 # use plain printf.

Note that printf is somewhat unsafe if var value is controlled by an attacker.

Ok, at that time got it done with the help of a friend and the code looks like this.

Sub Saving()

Dim part1 As String

Dim part2 As String


part1 = Range("C5").Value

part2 = Range("C8").Value


ActiveWorkbook.SaveAs Filename:= _

"C:\-docs\cmat\Desktop\pieteikumi\" & part1 & " " & part2 & ".xlsm", FileFormat:= _
xlOpenXMLWorkbookMacroEnabled, CreateBackup:=False

End Sub

How do I edit this part (FileFormat:= _ xlOpenXMLWorkbookMacroEnabled) for it to save as Excel 97-2013 Workbook, have tried several variations with no success. Thankyou

Seems, that I found the solution, but my idea is flawed. By doing this FileFormat:= _ xlOpenXMLWorkbook, it drops out a popup saying, the you cannot save this workbook as a file without Macro enabled. So, is this impossible?

Java does not support multiple inheritance because of two reasons:

1. In java, every class is a child of Object class. When it inherits from more than one super class, sub class gets the ambiguity to acquire the property of Object class..
2. In java every class has a constructor, if we write it explicitly or not at all. The first statement is calling super() to invoke the supper class constructor. If the class has more than one super class, it gets confused.

So when one class extends from more than one super class, we get compile time error.

A better and optimised solution to display multiple validation messages for a single element would be like this.

<div ng-messages="myForm.file.$error" ng-show="myForm.file.$touched">
 <span class="error" ng-message="required"> <your message> </span>
 <span class="error" ng-message="size"> <your message> </span>
 <span class="error" ng-message="filetype"> <your message> </span>
</div>

Controller Code should be the one suggested by @ Ben Lesh

How about something like this ...

var l1 = new List<int>() { 1,2,3,4,5,2,2,2,4,4,4,1 };

var g = l1.GroupBy( i => i );

foreach( var grp in g )
{
  Console.WriteLine( "{0} {1}", grp.Key, grp.Count() );
}

Edit per comment: I will try and do this justice. :)

In my example, it's a Func<int, TKey> because my list is ints. So, I'm telling GroupBy how to group my items. The Func takes a int and returns the the key for my grouping. In this case, I will get an IGrouping<int,int> (a grouping of ints keyed by an int). If I changed it to (i => i.ToString() ) for example, I would be keying my grouping by a string. You can imagine a less trivial example than keying by "1", "2", "3" ... maybe I make a function that returns "one", "two", "three" to be my keys ...

private string SampleMethod( int i )
{
  // magically return "One" if i == 1, "Two" if i == 2, etc.
}

So, that's a Func that would take an int and return a string, just like ...

i =>  // magically return "One" if i == 1, "Two" if i == 2, etc. 

But, since the original question called for knowing the original list value and it's count, I just used an integer to key my integer grouping to make my example simpler.

No comma after the last property.

Semicolon after alert(date);

Case on datepicker (not datePicker)

Check your other uppercase / lowercase for the properties.

$(function() {
    $('.date-pick').datepicker( {
        onSelect: function(date) {
            alert(date);
        },
        selectWeek: true,
        inline: true,
        startDate: '01/01/2000',
        firstDay: 1
    });
});

You can't do it with "anonymous" type parameters (ie, wildcards that use ?), but you can do it with "named" type parameters. Simply declare the type parameter at method or class level.

import java.util.List;
interface A{}
interface B{}
public class Test<E extends B & A, T extends List<E>> {
    T t;
}

Type in:

man lsof

Then look for -w, -n, and -i

-i: internet stuff -n: makes it faster -w: toggles warnings

There are WAY more details on the man pages

You simply need to add that line legend: { display: false }

Try to log the stack trace like below:

logger.error("Exception :: " , e);

If you want to get an array of ints, with values from 1 to 10, from a Stream<Integer>, there is IntStream at your disposal.

Here we create a Stream with a Stream.of method and convert a Stream<Integer> to an IntStream using a mapToInt. Then we can call IntStream's toArray method.

Stream<Integer> stream = Stream.of(1,2,3,4,5,6,7,8,9,10);
//or use this to create our stream 
//Stream<Integer> stream = IntStream.rangeClosed(1, 10).boxed();
int[] array =  stream.mapToInt(x -> x).toArray();

Here is the same thing, without the Stream<Integer>, using only the IntStream:

int[]array2 =  IntStream.rangeClosed(1, 10).toArray();

AsyncTask<CognitoCachingCredentialsProvider, Integer, Void> task = new 
AsyncTask<CognitoCachingCredentialsProvider, Integer, Void>() {

@Override
protected Void doInBackground(CognitoCachingCredentialsProvider... params) {
    AWSSessionCredentials creds = credentialsProvider.getCredentials();
    String id = credentialsProvider.getCachedIdentityId();
    credentialsProvider.refresh();
    Log.d("wooohoo", String.format("id=%s, token=%s", id, creds.getSessionToken()));
    return null;
    }
};

task.execute(credentialsProvider);

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

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

is what you want.

This solves my problem.

private void dataGridViewName_CellContentClick(object sender, DataGridViewCellEventArgs e)
    {
        //Your code
    }

I know the answers are relating to changing grouped table cells, but in case someone is wanting to also change the tableview's background color:

Not only do you need to set:

tableview.backgroundColor = color;

You also need to change or get rid of the background view:

tableview.backgroundView = nil;

You can use:

Insert into Event(Description,Date) values('teste', GETDATE());

Also, you can change your table so that 'Date' has a default, "GETDATE()"

You want to set its 'Format' property to be time and add a spin button control to it:

The static keyword modifies the lifecycle of a method or variable within a class. A static method or variable is created at the time a class is loaded. A method or variable that is not declared as static is created only when the class is instantiated as an object for example by using the new operator.

The lifecycle of a class, in broad terms, is:

1. the source code for the class is written creating a template or pattern or stamp which can then be used to
2. create an object with the new operator using the class to make an instance of the class as an actual object and then when done with the object
3. destroy the object reclaiming the resources it is holding such as memory during garbage collection.

In order to have an initial entry point for an application, Java has adopted the convention that the Java program must have a class that contains a method with an agreed upon or special name. This special method is called main(). Since the method must exist whether the class containing the main method has been instantiated or not, the main() method must be declared with the static modifier so that as soon as the class is loaded, the main() method is available.

The result is that when you start your Java application by a command line such as java helloworld a series of actions happen. First of all a Java Virtual Machine is started up and initialized. Next the helloworld.class file containing the compiled Java code is loaded into the Java Virtual Machine. Then the Java Virtual Machine looks for a method in the helloworld class that is called main(String [] args). this method must be static so that it will exist even though the class has not actually been instantiated as an object. The Java Virtual Machine does not create an instance of the class by creating an object from the class. It just loads the class and starts execution at the main() method.

So you need to create an instance of your class as an object and then you can access the methods and variables of the class that have not been declared with the static modifier. Once your Java program has started with the main() function you can then use any variables or methods that have the modifier of static since they exist as part of the class being loaded.

However, those variables and methods of the class which are outside of the main() method which do not have the static modifier can not be used until an instance of the class has been created as an object within the main() method. After creating the object you can then use the variables and methods of the object. An attempt to use the variables and methods of the class which do not have the static modifier without going through an object of the class is caught by the Java compiler at compile time and flagged as an error.

import java.io.*;

class HelloWorld {
    int myInt;      // this is a class variable that is unique to each object
    static int myInt2;  // this is a class variable shared by all objects of this class

    static void main (String [] args) {
        // this is the main entry point for this Java application
        System.out.println ("Hello, World\n");
        myInt2 = 14;    // able to access the static int
        HelloWorld myWorld = new HelloWorld();
        myWorld.myInt = 32;   // able to access non-static through an object
    }
}

If the file name is used as a parameter to the batch file, all you need is %~z1 (1 means first parameter)

If the file name is not a parameter, you can do something like:

@echo off
setlocal
set file="test.cmd"
set maxbytesize=1000

FOR /F "usebackq" %%A IN ('%file%') DO set size=%%~zA

if %size% LSS %maxbytesize% (
    echo.File is ^< %maxbytesize% bytes
) ELSE (
    echo.File is ^>= %maxbytesize% bytes
)

listOfSomething.Clear();
listOfSomething.Add("first");
collection.Add(listOfSomething);

You are clearing the list here and adding one element ("first"), the 1st reference of listOfSomething is updated as well sonce both reference the same object, so when you access the second element myList.get(1) (which does not exist anymore) you get the null.

Notice both collection.Add(listOfSomething); save two references to the same arraylist object.

You need to create two different instances for two elements:

ArrayList<ArrayList<String>> collection = new ArrayList<ArrayList<String>>();

ArrayList<String> listOfSomething1 = new ArrayList<String>();
listOfSomething1.Add("first");
listOfSomething1.Add("second");

ArrayList<String> listOfSomething2 = new ArrayList<String>();
listOfSomething2.Add("first");

collection.Add(listOfSomething1);    
collection.Add(listOfSomething2);

I found myself asking the same question and came up with a generic C++11 based solution, similar to soru's:

template <typename TENUM>
class FlagSet {

private:
    using TUNDER = typename std::underlying_type<TENUM>::type;
    std::bitset<std::numeric_limits<TUNDER>::max()> m_flags;

public:
    FlagSet() = default;

    template <typename... ARGS>
    FlagSet(TENUM f, ARGS... args) : FlagSet(args...)
    {   
        set(f);
    }   
    FlagSet& set(TENUM f)
    {   
        m_flags.set(static_cast<TUNDER>(f));
        return *this;
    }   
    bool test(TENUM f)
    {   
        return m_flags.test(static_cast<TUNDER>(f));
    }   
    FlagSet& operator|=(TENUM f)
    {   
        return set(f);
    }   
};

The interface can be improved to taste. Then it can be used like so:

FlagSet<Flags> flags{Flags::FLAG_A, Flags::FLAG_C};
flags |= Flags::FLAG_D;

For me it worked like that in Kotlin:

my string.xml

 <string name="price" formatted="false">Price:U$ %.2f%n</string>

my class.kt

 var formatPrice: CharSequence? = null
 var unitPrice = 9990
 formatPrice = String.format(context.getString(R.string.price), unitPrice/100.0)
 Log.d("Double_CharSequence", "$formatPrice")

D/Double_CharSequence: Price :U$ 99,90

For an even better result, we can do so

 <string name="price_to_string">Price:U$ %1$s</string>

 var formatPrice: CharSequence? = null
 var unitPrice = 199990
 val numberFormat = (unitPrice/100.0).toString()
 formatPrice = String.format(context.getString(R.string.price_to_string), formatValue(numberFormat))

  fun formatValue(value: String) :String{
    val mDecimalFormat = DecimalFormat("###,###,##0.00")
    val s1 = value.toDouble()
    return mDecimalFormat.format(s1)
 }

 Log.d("Double_CharSequence", "$formatPrice")

D/Double_CharSequence: Price :U$ 1.999,90

    NSDate *todaysDate = [NSDate new];
NSDateFormatter *formatter = [NSDateFormatter new];
[formatter setDateFormat:@"MM-dd-yyyy HH:mm:ss"];
NSString *strDateTime = [formatter stringFromDate:todaysDate];

NSString *strFileName = [NSString stringWithFormat:@"/Users/Shared/Recording_%@.mov",strDateTime];
NSLog(@"filename:%@",strFileName);

Log will be : filename:/Users/Shared/Recording_06-28-2016 12:53:26.mov

There is no standard Unix command, AFAIK. I haven't used Sun OS, but on Linux, you can use this:

cat /proc/cpuinfo

Sorry that it is Linux, not Sun OS. There is probably something similar though for Sun OS.

Abstraction- Abstraction in simple words can be said as a way out in which the user is kept away from the complex details or detailed working of some system. You can also assume it as a simple way to solve any problem at the design and interface level.

You can say the only purpose of abstraction is to hide the details that can confuse a user. So for simplification purposes, we can use abstraction. Abstraction is also a concept of object-oriented programming. It hides the actual data and only shows the necessary information. For example, in an ATM machine, you are not aware that how it works internally. Only you are concerned to use the ATM interface. So that can be considered as a type of abstraction process.

Encapsulation- Encapsulation is also part of object-oriented programming. In this, all you have to do is to wrap up the data and code together so that they can work as a single unit. it works at the implementation level. it also improves the application Maintainance.

Encapsulation focuses on the process which will save information. Here you have to protect your data from external use.

Here is a good starting point.

HTML:

<div class="containing-table">
    <div class="centre-align">
        <div class="content"></div>
    </div>
</div>

CSS:

.containing-table {
    display: table;
    width: 100%;
    height: 400px; /* for demo only */
    border: 1px dotted blue;
}
.centre-align {
    padding: 10px;
    border: 1px dashed gray;
    display: table-cell;
    text-align: center;
    vertical-align: middle;
}
.content {
    width: 50px;
    height: 50px;
    background-color: red;
    display: inline-block;
    vertical-align: top; /* Removes the extra white space below the baseline */
}

See demo at: http://jsfiddle.net/audetwebdesign/jSVyY/

.containing-table establishes the width and height context for .centre-align (the table-cell).

You can apply text-align and vertical-align to alter .centre-align as needed.

Note that .content needs to use display: inline-block if it is to be centered horizontally using the text-align property.

There is a difference between early performance optimization and using a best practice type of rule. If you are creating new tables where you will always have a fixed length field, it makes sense to use CHAR, you should be using it in that case. This isn't early optimization, but rather implementing a rule of thumb (or best practice).

i.e. - If you have a 2 letter state field, use CHAR(2). If you have a field with the actual state names, use VARCHAR.

@Override
public void onDraw(Canvas canvas){
    canvas.drawCircle(xPos, yPos,radius, paint);
}

Above is the code to render a circle. Tweak the parameters to your suiting.

You can't, Doctrine 2 doesn't allow for raw queries. It may seem like you can but if you try something like this:

$sql = "SELECT DATE_FORMAT(whatever.createdAt, '%Y-%m-%d') FORM whatever...";
$em = $this->getDoctrine()->getManager();
$em->getConnection()->exec($sql);

Doctrine will spit an error saying that DATE_FORMAT is an unknown function.

But my database (mysql) does know that function, so basically what is hapening is Doctrine is parsing that query behind the scenes (and behind your back) and finding an expression that it doesn't understand, considering the query to be invalid.

So if like me you want to be able to simply send a string to the database and let it deal with it (and let the developer take full responsibility for security), forget it.

Of course you could code an extension to allow that in some way or another, but you just as well off using mysqli to do it and leave Doctrine to it's ORM buisness.

You need to use the new android.animation framework (object animators) with FragmentTransaction.setCustomAnimations as well as FragmentTransaction.setTransition.

Here's an example on using setCustomAnimations from ApiDemos' FragmentHideShow.java:

ft.setCustomAnimations(android.R.animator.fade_in, android.R.animator.fade_out);

and here's the relevant animator XML from res/animator/fade_in.xml:

<objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:interpolator/accelerate_quad"
    android:valueFrom="0"
    android:valueTo="1"
    android:propertyName="alpha"
    android:duration="@android:integer/config_mediumAnimTime" />

Note that you can combine multiple animators using <set>, just as you could with the older animation framework.

EDIT: Since folks are asking about slide-in/slide-out, I'll comment on that here.

Slide-in and slide-out

You can of course animate the translationX, translationY, x, and y properties, but generally slides involve animating content to and from off-screen. As far as I know there aren't any transition properties that use relative values. However, this doesn't prevent you from writing them yourself. Remember that property animations simply require getter and setter methods on the objects you're animating (in this case views), so you can just create your own getXFraction and setXFraction methods on your view subclass, like this:

public class MyFrameLayout extends FrameLayout {
    ...
    public float getXFraction() {
        return getX() / getWidth(); // TODO: guard divide-by-zero
    }

    public void setXFraction(float xFraction) {
        // TODO: cache width
        final int width = getWidth();
        setX((width > 0) ? (xFraction * width) : -9999);
    }
    ...
}

Now you can animate the 'xFraction' property, like this:

res/animator/slide_in.xml:

<objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/linear_interpolator"
    android:valueFrom="-1.0"
    android:valueTo="0"
    android:propertyName="xFraction"
    android:duration="@android:integer/config_mediumAnimTime" />

Note that if the object you're animating in isn't the same width as its parent, things won't look quite right, so you may need to tweak your property implementation to suit your use case.

\w\- is probably the best but here just another alternative
Use [:alnum:]

I was running on the same problem, wampmysqld64 did not start, so I checked the Mysql log which you should find it inside the main wamp64 folder, and I found all the details on why is not working. on my computer I found another mysql instance is running so it prevents the wampmysqld64 to start. I stopped the other instance, and everything works fine after.

The developer advocate for YouTube gave a talk about scaling Python at PyCon 2012, which is also relevant to scaling Django.

YouTube has more than a billion users, and YouTube is built on Python.

Ran into this on CentOs 5.4. Noticed that lib64 contained the crt*.o files, but lib did not. Installed glibc-devel through yum which installed the i386 bits and this resolved my issue.

You can use System.IO.Directory.GetParent() to retrieve the parent directory of a given directory.

While there is probably an agnostic way to describe these, it does seem to be conflicting with various statements from answers to websites.

Let's be very clear and direct here. If you are a .NET developer working with Web API, the facts are (from the Microsoft API documentation), http://www.asp.net/web-api/overview/creating-web-apis/creating-a-web-api-that-supports-crud-operations:

1. PUT = UPDATE (/api/products/id)
2. MCSD Exams 2014 -  UPDATE = PUT, there are **NO** multiple answers for that question period.

Sure you "can" use "POST" to update, but just follow the conventions laid out for you with your given framework. In my case it is .NET / Web API, so PUT is for UPDATE there is no debate.

I hope this helps any Microsoft developers that read all comments with Amazon and Sun/Java website links.

As others said, libreoffice can convert xls files to csv. The problem for me was the sheet selection.

This libreoffice Python script does a fine job at converting a single sheet to CSV.

Usage is:

./libreconverter.py File.xls:"Sheet Name" output.csv

The only downside (on my end) is that --headless doesn't seem to work. I have a LO window that shows up for a second and then quits.
That's OK with me, it's the only tool that does the job rapidly.

all: program1 program2

program1:
    gcc -Wall -ansi -pedantic -o prog1 program1.c

program2:
    gcc -Wall -ansi -pedantic -o prog2 program2.c

I rather the ansi and pedantic, a better control for your program. It wont let you compile while you still have warnings !!

Try this:

string decodedUrl = HttpUtility.UrlDecode("my.aspx?val=%2Fxyz2F");

Not mouse position, but, if you're looking for current cursor postion (for use cases like getting last typed character etc) then, below snippet works fine.
This will give you the cursor index related to text content.

window.getSelection().getRangeAt(0).startOffset

Setter: public void setCurrent(boolean val)
Getter: public boolean getCurrent()

For booleans you can also use

public boolean isCurrent()

If you are writing a DLL that encapsulates a ton of complex functionality into a simple public API, then “internal” is used on the class members which are not to be exposed publicly.

Hiding complexity (a.k.a. encapsulation) is the chief concept of quality software engineering.

The user "geoand" is right in pointing out the reasons here and giving a solution. But a better approach is to encapsulate your configuration into a separate class, say SystemContiguration java class and then inject this class into what ever services you want to use those fields.

Your current way(@grahamrb) of reading config values directly into services is error prone and would cause refactoring headaches if config setting name is changed.

What I need is to use Docker with MariaDb on different port /3301/ on my Ubuntu machine because I already had MySql installed and running on 3306.

To do this after half day searching did it using:

docker run -it -d -p 3301:3306 -v ~/mdbdata/mariaDb:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=root --name mariaDb mariadb

This pulls the image with latest MariaDb, creates container called mariaDb, and run mysql on port 3301. All data of which is located in home directory in /mdbdata/mariaDb.

To login in mysql after that can use:

mysql -u root -proot -h 127.0.0.1 -P3301

I had the exact same situation. It was caused by not having a PropertySourcesPlaceholderConfigurer in the Spring context, which resolves values against the @Value annotation inside of classes.

Include a property placeholder to solve the problem, no need to use Spring expressions for integers (the property file does not have to exist if you use ignore-resource-not-found="true"):

<context:property-placeholder location="/path/to/my/app.properties"
    ignore-resource-not-found="true" />

Since you claim to be used to JavaScript:

The Python in operator is similar to the JavaScript in operator.

Here's some JavaScript:

var d = {1: 2, 3: 4};
if (1 in d) {
    alert('true!');
}

And the equivalent Python:

d = {1: 2, 3: 4}
if 1 in d:
    print('true!')

With objects/dicts, they're nearly identical, both checking whether 1 is a key of the object/dict. The big difference, of course, is that JavaScript is sloppily-typed, so '1' in d would be just as true.

With arrays/lists, they're very different. A JS array is an object, and its indexes are the keys, so 1 in [3, 4, 5] will be true. A Python list is completely different from a dict, and its in operator checks the values, not the indexes, which tends to be more useful. And Python extends this behavior to all iterables.

With strings, they're even more different. A JS string isn't an object, so you will get a TypeError. But a Python str or unicode will check whether the other operand is a substring. (This means 1 in '123' is illegal, because 1 can't be a substring of anything, but '1' in '123' is true.)

With objects as objects, in JS there is of course no distinction, but in Python, objects are instances of classes, not dicts. So, in JS, 1 in d will be true for an object if it has a member or method named '1', but in Python, it's up to your class what it means—Python will call d.__contains__(1), then, if that fails, it tries to use your object as an utterable (by calling its __iter__, and, if that fails, by trying to index it with integers starting from 0).

Also, note that JS's in, because it's actually checking for object membership, does the usual JS method-resolution-order search, while Python's in, because it's checking for keys of a dict, members of a sequence, etc., does no such thing. So, technically, it's probably a bit closer to the hasOwnProperty method than the in operator.

Although this question is old, it is still relevant for my more or less up-to-date system. After enabling debug mode of sudo (Debug sudo /var/log/sudo_debug all@info in /etc/sudo.conf) I was pointed to /dev: "/dev is world writable". So you might need to check the tty file permissions, especially those of the directory where the tty/pts node resides in.

<input type="text" name="myinput" id="myinput" onkeypress="return isNumber(event);" />

and in the js:

function isNumber(e){
    e = e || window.event;
    var charCode = e.which ? e.which : e.keyCode;
    return /\d/.test(String.fromCharCode(charCode));
}

or you can write it in a complicated bu useful way:

<input onkeypress="return /\d/.test(String.fromCharCode(((event||window.event).which||(event||window.event).which)));" type="text" name="myinput" id="myinput" />

Note:cross-browser and regex in literal.

The pickle Python library implements binary protocols for serializing and de-serializing a Python object.

When you import torch (or when you use PyTorch) it will import pickle for you and you don't need to call pickle.dump() and pickle.load() directly, which are the methods to save and to load the object.

In fact, torch.save() and torch.load() will wrap pickle.dump() and pickle.load() for you.

A state_dict the other answer mentioned deserves just few more notes.

What state_dict do we have inside PyTorch? There are actually two state_dicts.

The PyTorch model is torch.nn.Module has model.parameters() call to get learnable parameters (w and b). These learnable parameters, once randomly set, will update over time as we learn. Learnable parameters are the first state_dict.

The second state_dict is the optimizer state dict. You recall that the optimizer is used to improve our learnable parameters. But the optimizer state_dict is fixed. Nothing to learn in there.

Because state_dict objects are Python dictionaries, they can be easily saved, updated, altered, and restored, adding a great deal of modularity to PyTorch models and optimizers.

Let's create a super simple model to explain this:

import torch
import torch.optim as optim

model = torch.nn.Linear(5, 2)

# Initialize optimizer
optimizer = optim.SGD(model.parameters(), lr=0.001, momentum=0.9)

print("Model's state_dict:")
for param_tensor in model.state_dict():
    print(param_tensor, "\t", model.state_dict()[param_tensor].size())

print("Model weight:")    
print(model.weight)

print("Model bias:")    
print(model.bias)

print("---")
print("Optimizer's state_dict:")
for var_name in optimizer.state_dict():
    print(var_name, "\t", optimizer.state_dict()[var_name])

This code will output the following:

Model's state_dict:
weight   torch.Size([2, 5])
bias     torch.Size([2])
Model weight:
Parameter containing:
tensor([[ 0.1328,  0.1360,  0.1553, -0.1838, -0.0316],
        [ 0.0479,  0.1760,  0.1712,  0.2244,  0.1408]], requires_grad=True)
Model bias:
Parameter containing:
tensor([ 0.4112, -0.0733], requires_grad=True)
---
Optimizer's state_dict:
state    {}
param_groups     [{'lr': 0.001, 'momentum': 0.9, 'dampening': 0, 'weight_decay': 0, 'nesterov': False, 'params': [140695321443856, 140695321443928]}]

Note this is a minimal model. You may try to add stack of sequential

model = torch.nn.Sequential(
          torch.nn.Linear(D_in, H),
          torch.nn.Conv2d(A, B, C)
          torch.nn.Linear(H, D_out),
        )

Note that only layers with learnable parameters (convolutional layers, linear layers, etc.) and registered buffers (batchnorm layers) have entries in the model's state_dict.

Non learnable things, belong to the optimizer object state_dict, which contains information about the optimizer's state, as well as the hyperparameters used.

The rest of the story is the same; in the inference phase (this is a phase when we use the model after training) for predicting; we do predict based on the parameters we learned. So for the inference, we just need to save the parameters model.state_dict().

torch.save(model.state_dict(), filepath)

And to use later model.load_state_dict(torch.load(filepath)) model.eval()

Note: Don't forget the last line model.eval() this is crucial after loading the model.

Also don't try to save torch.save(model.parameters(), filepath). The model.parameters() is just the generator object.

On the other side, torch.save(model, filepath) saves the model object itself, but keep in mind the model doesn't have the optimizer's state_dict. Check the other excellent answer by @Jadiel de Armas to save the optimizer's state dict.

If you're looking for currency formatting (which you didn't specify, but it seems that is what you're looking for) try the NumberFormat class. It's very simple:

double d = 2.3d;
NumberFormat formatter = NumberFormat.getCurrencyInstance();
String output = formatter.format(d);

Which will output (depending on locale):

$2.30

Also, if currency isn't required (just the exact two decimal places) you can use this instead:

NumberFormat formatter = NumberFormat.getNumberInstance();
formatter.setMinimumFractionDigits(2);
formatter.setMaximumFractionDigits(2);
String output = formatter.format(d);

Which will output 2.30

Not surprisingly, this error can arise when another process is listening on the desired port. This happened today when I started an instance of the Apache Web server, listening on its default port (80), having forgotten that I already had IIS 7 running, and listening on that port. This is well explained in Port 80 is being used by SYSTEM (PID 4), what is that? Better yet, that article points to Stop http.sys from listening on port 80 in Windows, which explains a very simple way to resolve it, with just a tad of help from an elevated command prompt and a one-line edit of my hosts file.

URLs are not resolved based on the file structure in the server side. URLs are resolved based on the real public web addresses of the resources in question. It's namely the webbrowser who has got to invoke them, not the webserver.

There are several ways to soften the pain:

JSF EL offers a shorthand to ${pageContext.request} in flavor of #{request}:

<li><a href="#{request.contextPath}/index.xhtml">Home</a></li>
<li><a href="#{request.contextPath}/about_us.xhtml">About us</a></li>

You can if necessary use <c:set> tag to make it yet shorter. Put it somewhere in the master template, it'll be available to all pages:

<c:set var="root" value="#{request.contextPath}/" />
...
<li><a href="#{root}index.xhtml">Home</a></li>
<li><a href="#{root}about_us.xhtml">About us</a></li>

JSF 2.x offers the <h:link> which can take a view ID relative to the context root in outcome and it will append the context path and FacesServlet mapping automatically:

<li><h:link value="Home" outcome="index" /></li>
<li><h:link value="About us" outcome="about_us" /></li>

HTML offers the <base> tag which makes all relative URLs in the document relative to this base. You could make use of it. Put it in the <h:head>.

<base href="#{request.requestURL.substring(0, request.requestURL.length() - request.requestURI.length())}#{request.contextPath}/" />
...
<li><a href="index.xhtml">Home</a></li>
<li><a href="about_us.xhtml">About us</a></li>

(note: this requires EL 2.2, otherwise you'd better use JSTL fn:substring(), see also this answer)

This should end up in the generated HTML something like as

<base href="http://example.com/webname/" />

Note that the <base> tag has a caveat: it makes all jump anchors in the page like <a href="#top"> relative to it as well! See also Is it recommended to use the <base> html tag? In JSF you could solve it like <a href="#{request.requestURI}#top">top</a> or <h:link value="top" fragment="top" />.

Try either

• sudo apt-get install php-zip or
• sudo apt-get install php5.6-zip

Then, you might have to restart your web server.

• sudo service apache2 restart or
• sudo service nginx restart

If you are installing on centos or fedora OS then use yum in place of apt-get. example:-

sudo yum install php-zip or sudo yum install php5.6-zip and sudo service httpd restart

You can put below property in listview tag

android:divider="@null"

(or) programmatically listview.Divider(null); here listview is ListView reference.

To clear all the webview caches while you signOUT form your APP:

CookieSyncManager.createInstance(this);         
CookieManager cookieManager = CookieManager.getInstance();        
cookieManager.removeAllCookie();

For Lollipop and above:

CookieSyncManager.createInstance(this);         
CookieManager cookieManager = CookieManager.getInstance();        
cookieManager.removeAllCookies(ValueCallback);

Since Entity Framework 5.0 you can use following code in order to solve your issue:

public abstract class YourContext : DbContext
{
  public YourContext()
  {
    (this as IObjectContextAdapter).ObjectContext.ContextOptions.UseCSharpNullComparisonBehavior = true;
  }
}

This should solve your problems as Entity Framerwork will use 'C# like' null comparison.
