You can control the behavior in a headerfile or C-file:

#pragma warning(error:4003) //not enough actual parameters for macro

yet tested with Visual studio 2015. I have a common headerfile 'compl_adaption.h' for such things, included in all files, to set this behavior for all my projects compiled on visual studio.

For me, the only thing that worked in Java 7 on OS X 10.9 was this:

// driver = new RemoteWebDriver(new URL(grid), capability);
driver.manage().window().setPosition(new Point(0,0));
driver.manage().window().setSize(new Dimension(1024,768));

Where 1024 is the width, and 768 is the height.

int is a primitive type. Variables of type int store the actual binary value for the integer you want to represent. int.parseInt("1") doesn't make sense because int is not a class and therefore doesn't have any methods.

Integer is a class, no different from any other in the Java language. Variables of type Integer store references to Integer objects, just as with any other reference (object) type. Integer.parseInt("1") is a call to the static method parseInt from class Integer (note that this method actually returns an int and not an Integer).

To be more specific, Integer is a class with a single field of type int. This class is used where you need an int to be treated like any other object, such as in generic types or situations where you need nullability.

Note that every primitive type in Java has an equivalent wrapper class:

• byte has Byte
• short has Short
• int has Integer
• long has Long
• boolean has Boolean
• char has Character
• float has Float
• double has Double

Wrapper classes inherit from Object class, and primitive don't. So it can be used in collections with Object reference or with Generics.

Since java 5 we have autoboxing, and the conversion between primitive and wrapper class is done automatically. Beware, however, as this can introduce subtle bugs and performance problems; being explicit about conversions never hurts.

Shorter:

   Split(stringval,":")(0)

Yes you can. By changing the android:label field in your application node in AndroidManifest.xml.

Note: If you have added a Splash Screen and added

<intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

to your Splash Screen, then the Launcher Icon name will be changed to the name of your Splash Screen Class name.

Please make sure that you change label:

android:label="@string/title_activity_splash_screen"

in your Splash Screen activity in your strings.xml file. It can be found in Res -> Values -> strings.xml

git status is your friend, use it often. Good for answering questions like:

• What did that command just do?
• What branch am I on?
• What changes am I about to commit, and have I forgotten anything?
• Was I in the middle of something last time I worked on this project (days, weeks, or perhaps months ago)?

Unlike, say svn status, git status runs nigh-instantly even on large projects. I often found it reassuring while learning git to use it frequently, to make sure my mental model of what was going on was accurate. Now I mostly just use it to remind myself what I've changed since my last commit.

Obviously, it's much more useful if your .gitignore is sanely configured.

Use git rebase --abort. From the official Linux kernel documentation for git rebase:

git rebase --continue | --skip | --abort | --edit-todo

Here is an ES6 version of Stoive's answer:

export class ImageDataConverter {
  constructor(dataURI) {
    this.dataURI = dataURI;
  }

  getByteString() {
    let byteString;
    if (this.dataURI.split(',')[0].indexOf('base64') >= 0) {
      byteString = atob(this.dataURI.split(',')[1]);
    } else {
      byteString = decodeURI(this.dataURI.split(',')[1]);
    }
    return byteString;
  }

  getMimeString() {
    return this.dataURI.split(',')[0].split(':')[1].split(';')[0];
  }

  convertToTypedArray() {
    let byteString = this.getByteString();
    let ia = new Uint8Array(byteString.length);
    for (let i = 0; i < byteString.length; i++) {
      ia[i] = byteString.charCodeAt(i);
    }
    return ia;
  }

  dataURItoBlob() {
    let mimeString = this.getMimeString();
    let intArray = this.convertToTypedArray();
    return new Blob([intArray], {type: mimeString});
  }
}

Usage:

const dataURL = canvas.toDataURL('image/jpeg', 0.5);
const blob = new ImageDataConverter(dataURL).dataURItoBlob();
let fd = new FormData(document.forms[0]);
fd.append("canvasImage", blob);

If your application needs to handle money values up to a trillion then this should work: 13,2 If you need to comply with GAAP (Generally Accepted Accounting Principles) then use: 13,4

Usually you should sum your money values at 13,4 before rounding of the output to 13,2.

As an alternative option, could you use the "accept" attribute of HTML File Input which defines which MIME types are acceptable.

Definition here

In PostreSQL you can use SIMILAR TO operator (more):

-- only digits
select * from books where title similar to '^[0-9]*$';
-- start with digit
select * from books where title similar to '^[0-9]%$';

Putting a <br clear="all" /> after the last floated div worked the best for me. Thanks to Brent Fiare & Paul Waite for the info that floated divs will not expand the height of the parent div! This has been driving me nuts! ;-}

I faced the same problem. Updating bash_profile with the following lines, solved the problem for me:

export JAVA_HOME='/usr/'

export PATH=${JAVA_HOME}/bin:$PATH

You can use an HTML to PDF tool like wkhtmltopdf. And then you can use a PDF to image tool like imagemagick. Admittedly this is server side and a very convoluted process...

This almost worked for me.

<input type='radio' name='radioBtn'>
<input type='radio' name='radioBtn'>
<input type='radio' name='radioBtn'>

$(document).on("click", "input[name='radioBtn']", function(){
    thisRadio = $(this);
    if (thisRadio.hasClass("imChecked")) {
        thisRadio.removeClass("imChecked");
        thisRadio.prop('checked', false);
    } else { 
        thisRadio.prop('checked', true);
        thisRadio.addClass("imChecked");
    };
})

But If I check a radio button, then check another and try to check the first one again I must do two clicks. This is because it has the class imChecked. I just needed to uncheck the other radio buttons before the verification.

Add this line makes it work:

$("input[name='radioBtn']").not(thisRadio).removeClass("imChecked");

<input type='radio' name='radioBtn'>
<input type='radio' name='radioBtn'>
<input type='radio' name='radioBtn'>

$(document).on("click", "input[name='radioBtn']", function(){
    thisRadio = $(this);
    $("input[name='radioBtn']").not(thisRadio).removeClass("imChecked");
    if (thisRadio.hasClass("imChecked")) {
        thisRadio.removeClass("imChecked");
        thisRadio.prop('checked', false);
    } else { 
        thisRadio.prop('checked', true);
        thisRadio.addClass("imChecked");
    };
})

What even is ‘children’?

The React docs say that you can use props.children on components that represent ‘generic boxes’ and that don’t know their children ahead of time. For me, that didn’t really clear things up. I’m sure for some, that definition makes perfect sense but it didn’t for me.

My simple explanation of what this.props.children does is that it is used to display whatever you include between the opening and closing tags when invoking a component.

A simple example:

Here’s an example of a stateless function that is used to create a component. Again, since this is a function, there is no this keyword so just use props.children

const Picture = (props) => {
  return (
    <div>
      <img src={props.src}/>
      {props.children}
    </div>
  )
}

This component contains an <img> that is receiving some props and then it is displaying {props.children}.

Whenever this component is invoked {props.children} will also be displayed and this is just a reference to what is between the opening and closing tags of the component.

//App.js
render () {
  return (
    <div className='container'>
      <Picture key={picture.id} src={picture.src}>
          //what is placed here is passed as props.children  
      </Picture>
    </div>
  )
}

Instead of invoking the component with a self-closing tag <Picture /> if you invoke it will full opening and closing tags <Picture> </Picture> you can then place more code between it.

This de-couples the <Picture> component from its content and makes it more reusable.

Reference: A quick intro to React’s props.children

This question is really old, but I came across this page when I was looking for the easiest and quickest way to do this. Using Webpack is much simpler:

install webpack-dev-server

npm i -g webpack-dev-server

start webpack-dev-server with https

webpack-dev-server --https

The ALTER TABLE MySQL command should do the trick. The following command will change the default character set of your table and the character set of all its columns to UTF8.

ALTER TABLE etape_prospection CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;

This command will convert all text-like columns in the table to the new character set. Character sets use different amounts of data per character, so MySQL will convert the type of some columns to ensure there's enough room to fit the same number of characters as the old column type.

I recommend you read the ALTER TABLE MySQL documentation before modifying any live data.

If this is the offending line:

db.Responses.Where(y => y.ResponseId.Equals(item.ResponseId)).First();

Then it's because there is no object in Responses for which the ResponseId == item.ResponseId, and you can't get the First() record if there are no matches.

Try this instead:

var response
  = db.Responses.Where(y => y.ResponseId.Equals(item.ResponseId)).FirstOrDefault();

if (response != null)
{
    // take some alternative action
}
else
    temp.Response = response;

The FirstOrDefault() extension returns an objects default value if no match is found. For most objects (other than primitive types), this is null.

Try...

$("#captureAudio").prop('checked', false); 

One option is to pass in Bar.class (or whatever type you're interested in - any way of specifying the appropriate Class<T> reference) and keep that value as a field:

public class Test {
    public static void main(String[] args) throws IllegalAccessException,
            InstantiationException {
        Generic<Bar> x = new Generic<>(Bar.class);
        Bar y = x.buildOne();
    }
}

public class Generic<T> {
    private Class<T> clazz;

    public Generic(Class<T> clazz) {
        this.clazz = clazz;
    }

    public T buildOne() throws InstantiationException, IllegalAccessException {
        return clazz.newInstance();
    }
}

public class Bar {
    public Bar() {
        System.out.println("Constructing");
    }
}

Another option is to have a "factory" interface, and you pass a factory to the constructor of the generic class. That's more flexible, and you don't need to worry about the reflection exceptions.

If u want to add Hello world at the end of each line:

:%s/$/HelloWorld/

If you want to do this for specific number of line say, from 20 to 30 use:

:20,30s/$/HelloWorld/

If u want to do this at start of each line then use:

:20,30s/^/HelloWorld/

The accepted answer doesn't work for me, I did it as below.

$( function() {
  $( "#datepicker" ).datepicker();
  $('#getLastDateOfMon').on('click', function(){
    var date = $('#datepicker').val();

    // Format 'mm/dd/yy' eg: 12/31/2018
    var parts = date.split("/");

    var lastDateOfMonth = new Date();
                lastDateOfMonth.setFullYear(parts[2]);
                lastDateOfMonth.setMonth(parts[0]);
                lastDateOfMonth.setDate(0);

     alert(lastDateOfMonth.toLocaleDateString());
  });
});

We can access super class elements by using super keyword

Consider we have two classes, Parent class and Child class, with different implementations of method foo. Now in child class if we want to call the method foo of parent class, we can do so by super.foo(); we can also access parent elements by super keyword.

    class parent {
    String str="I am parent";
    //method of parent Class
    public void foo() {
        System.out.println("Hello World " + str);
    }
}

class child extends parent {
    String str="I am child";
    // different foo implementation in child Class
    public void foo() {
        System.out.println("Hello World "+str);
    }

    // calling the foo method of parent class
    public void parentClassFoo(){
        super.foo();
    }

    // changing the value of str in parent class and calling the foo method of parent class
    public void parentClassFooStr(){
        super.str="parent string changed";
        super.foo();
    }
}


public class Main{
        public static void main(String args[]) {
            child obj = new child();
            obj.foo();
            obj.parentClassFoo();
            obj.parentClassFooStr();
        }
    }

Without any configuration, you can simply issue the following command (modifying myusername and mydomain with your own information):

cntlm -u myusername -d mydomain -H

or

cntlm -u myusername@mydomain -H

It will ask you the password of myusername and will give you the following output:

PassLM          1AD35398BE6565DDB5C4EF70C0593492
PassNT          77B9081511704EE852F94227CF48A793
PassNTLMv2      A8FC9092D566461E6BEA971931EF1AEC    # Only for user 'myusername', domain 'mydomain'

Then create the file cntlm.ini (or cntlm.conf on Linux using default path) with the following content (replacing your myusername, mydomain and A8FC9092D566461E6BEA971931EF1AEC with your information and the result of the previous command):

Username    myusername
Domain      mydomain

Proxy       my_proxy_server.com:80
NoProxy     127.0.0.*, 192.168.*

Listen      127.0.0.1:5865
Gateway     yes

SOCKS5Proxy 5866

Auth        NTLMv2
PassNTLMv2  A8FC9092D566461E6BEA971931EF1AEC

Then you will have a local open proxy on local port 5865 and another one understanding SOCKS5 protocol at local port 5866.

Shorter version:

dependencies {
    implementation fileTree('lib')
}

const destroy = container => {
  document.getElementById(container).innerHTML = '';
};

Faster previous

const destroyFast = container => {
  const el = document.getElementById(container);
  while (el.firstChild) el.removeChild(el.firstChild);
};

I had the same problem. I changed the Version of Assembly in AssemblyInfo.cs in the Properties Folder. But, I don't have any idea why this problem happened. Maybe the compiler doesn't understand that this dll is newer, just changing the version of Assembly.

Basically, you have three options:

1. Neither specify EXPOSE nor -p
2. Only specify EXPOSE
3. Specify EXPOSE and -p

1) If you specify neither EXPOSE nor -p, the service in the container will only be accessible from inside the container itself.

2) If you EXPOSE a port, the service in the container is not accessible from outside Docker, but from inside other Docker containers. So this is good for inter-container communication.

3) If you EXPOSE and -p a port, the service in the container is accessible from anywhere, even outside Docker.

The reason why both are separated is IMHO because:

• choosing a host port depends on the host and hence does not belong to the Dockerfile (otherwise it would be depending on the host),
• and often it's enough if a service in a container is accessible from other containers.

The documentation explicitly states:

The EXPOSE instruction exposes ports for use within links.

It also points you to how to link containers, which basically is the inter-container communication I talked about.

PS: If you do -p, but do not EXPOSE, Docker does an implicit EXPOSE. This is because if a port is open to the public, it is automatically also open to other Docker containers. Hence -p includes EXPOSE. That's why I didn't list it above as a fourth case.

I recommend using python-dateutil. Its parser has been able to parse every date format I've thrown at it so far.

>>> from dateutil import parser
>>> parser.parse("Tue Jun 22 07:46:22 EST 2010")
datetime.datetime(2010, 6, 22, 7, 46, 22, tzinfo=tzlocal())
>>> parser.parse("Fri, 11 Nov 2011 03:18:09 -0400")
datetime.datetime(2011, 11, 11, 3, 18, 9, tzinfo=tzoffset(None, -14400))
>>> parser.parse("Sun")
datetime.datetime(2011, 12, 18, 0, 0)
>>> parser.parse("10-11-08")
datetime.datetime(2008, 10, 11, 0, 0)

and so on. No dealing with strptime() format nonsense... just throw a date at it and it Does The Right Thing.

Update: Oops. I missed in your original question that you mentioned that you used dateutil, sorry about that. But I hope this answer is still useful to other people who stumble across this question when they have date parsing questions and see the utility of that module.

This one would also work:

google.maps.event.addListener(marker, 'click', function() {
                if(!marker.open){
                    infowindow.open(map,marker);
                    marker.open = true;
                }
                else{
                    infowindow.close();
                    marker.open = false;
                }
            });

Which will open an infoWindow when clicked on it, close it when clicked on it if it was opened.

Also having seen Logan's solution, these 2 can be combined into this:

google.maps.event.addListener(marker, 'click', function() {
                if(!marker.open){
                    infowindow.open(map,marker);
                    marker.open = true;
                }
                else{
                    infowindow.close();
                    marker.open = false;
                }
                google.maps.event.addListener(map, 'click', function() {
                    infowindow.close();
                    marker.open = false;
                });
            });

Which will open an infoWindow when clicked on it, close it when clicked on it and it was opened, and close it if it's clicked anywhere on the map and the infoWindows was opened.

I assume that what you want is a tooltip. The easiest way to do this is to append an svg:title element to each circle, as the browser will take care of showing the tooltip and you don't need the mousehandler. The code would be something like

vis.selectAll("circle")
   .data(datafiltered).enter().append("svg:circle")
   ...
   .append("svg:title")
   .text(function(d) { return d.x; });

If you want fancier tooltips, you could use tipsy for example. See here for an example.

Your syntax isn't quite right: you need to list the fields in order before the INTO, and the corresponding target variables after:

SELECT Id, dateCreated
INTO iId, dCreate
FROM products
WHERE pName = iName

How dumb is this solution?

def is_number?(i)
  begin
    i+0 == i
  rescue TypeError
    false
  end
end

If your date column is a string of the format '2017-01-01' you can use pandas astype to convert it to datetime.

df['date'] = df['date'].astype('datetime64[ns]')

or use datetime64[D] if you want Day precision and not nanoseconds

print(type(df_launath['date'].iloc[0]))

yields

<class 'pandas._libs.tslib.Timestamp'> the same as when you use pandas.to_datetime

You can try it with other formats then '%Y-%m-%d' but at least this works.

Typing in $(this) will return the jQuery element instead of the HTML Element. Then it just depends on what you want to do in the click event.

alert($(this));

document.querySelector("label[for=" + vHtmlInputElement.id + "]");

This answers the question in the simplest and leanest manner. This uses vanilla javascript and works on all main-stream proper browsers.

You just need to perform a selector with a delay - (0 seconds works).

override func viewDidLoad() {
    super.viewDidLoad()
    perform(#selector(presentExampleController), with: nil, afterDelay: 0)
}

@objc private func presentExampleController() {
    let exampleStoryboard = UIStoryboard(named: "example", bundle: nil)
    let exampleVC = storyboard.instantiateViewController(withIdentifier: "ExampleVC") as! ExampleVC
    present(exampleVC, animated: true) 
}

<script type="text/javascript">
jQuery(function () {
    var container = jQuery("\#content");
    jQuery(container)
     .kendoGrid({
         selectable: "single row",
         dataSource: new kendo.data.DataSource({
             transport: {
                 read: {
                     url: "@Url.Action("GetMsgDetails", "OutMessage")" + "?msgId=" + msgId,
                     dataType: "json",
                 },
             },
             batch: true,
         }),
         editable: "popup",
         columns: [
            { field: "Id", title: "Id", width: 250, hidden: true },
            { field: "Data", title: "Message Body", width: 100 },
           { field: "mobile", title: "Mobile Number", width: 100 },
         ]
     });
});

Try wrapping the spans in an anchor tag and apply the background image to that.

HTML:

<div class="header">
    <a href="/">
        <span class="header-title">My gray sea design</span><br />
        <span class="header-title-two">A beautiful design</span>
    </a>
</div>

CSS:

.header {
    border-bottom:1px solid #eaeaea;
}

.header a {
    display: block;
    background-image: url("./images/embouchure.jpg");
    background-repeat: no-repeat;
    height:160px;
    padding-left:280px;
    padding-top:50px;
    width:470px;
    color: #eaeaea;

In my case i had a findViewById reference to a view i had deleted in xml

if you are running AS 3.1 and above:

1. go to Settings > Build, Execution and Deployment > compiler
2. add --stacktrace to the command line options, click apply and ok
3. At the bottom of AS click on Console/Build(If you use the stable version 3.1.2 and above) expand the panel and run your app again.

you should see the full stacktrace in the expanded view and the specific error.

Use FormulaR1C1:

Cells((1,3),(10,3)).FormulaR1C1 = "=RC[-2]+RC[-1]"

Unlike Formula, FormulaR1C1 has relative referencing.

Wrong syntax. Here you are:

insert into user_by_category (game_category,customer_id) VALUES ('Goku','12');

or:

insert into user_by_category ("game_category","customer_id") VALUES ('Kakarot','12');

The second one is normally used for case-sensitive column names.

This should get your sorted:

• Highlight from the end of the first line, to the very beginning of the third line.
• Use the Ctrl + H to bring up the 'Find and Replace' window.
• The highlighed region will already be plased in the 'Find' textbox.
• Replace with: \r\n
• 'Replace All' will then remove all the additional line spaces not required.

Here's how it should look:

in bootstrap 3 here are the classes to change the text color:

<p class="text-warning">...</p> //orangish,yellow

For anyone that wants to download jdk 8 without an oracle account: https://download.oracle.com/otn-pub/java/jdk/8u271-b09/61ae65e088624f5aaa0b1d2d801acb16/jdk-8u271-windows-x64.exe copy and paste the link. Jdk 15 didn't work for me so i tried using jdk 8 and it worked.

The original answer the author gave works pretty well. Just to extend this idea, you can do something like

group by datediff(minute, 0, [Date])/10

which will allow you to group by a longer period then 60 minutes, say 720, which is half a day etc.

A simple way to do it using python :

Python
import numpy as np
import imageio

image = imageio.imread(r'[image-path]', as_gray=True)

# getting the threshold value
thresholdValue = np.mean(image)

# getting the dimensions of the image
xDim, yDim = image.shape

# turn the image into a black and white image
for i in range(xDim):
    for j in range(yDim):
        if (image[i][j] > thresholdValue):
            image[i][j] = 255
        else:
            image[i][j] = 0

for refresh my table I do this:

In my ControllerA who named RequisicionesController I do this

@FXML public TableView<Requisiciones>  reqtable;

public TableView<Requisiciones> getReqtable() {
    return reqtable;
}

public void setReqtable(TableView<Requisiciones> reqtable) {
    this.reqtable = reqtable;
}

in the FXML loader I get ControllerB who also named RevisionReqController

RevisionReqController updateReq = cargarevisionreq.<RevisionReqController>getController();

RequisicionesController.this.setReqtable(selecciondedatosreq());                  
updateReq.setGetmodeltable(RequisicionesController.this.getReqtable());

in my ControllerB I do this:

public TableView<Requisiciones>  getmodeltable;     

public TableView<Requisiciones> getGetmodeltable() {
    return getmodeltable;
}

public void setGetmodeltable(TableView<Requisiciones> getmodeltable) {
    this.getmodeltable = getmodeltable;
}

then:

public void refresh () {
    mybutton.setonMouseClicked(e -> {
    ObservableList<Requisiciones> datostabla = FXCollections.observableArrayList();
    try {
        // rest of code

        String Query= " select..";

        PreparedStatement pss =Conexion.prepareStatement(Query);
        ResultSet rs = pss.executeQuery();
        while(rs.next()) {
            datostabla.add(new Requisiciones(
                // al requisiciones data
            ));
        }
        RevisionReqController.this.getGetmodeltable().getItems().clear();
        RevisionReqController.this.getGetmodeltable().setItems(datostabla);
    } catch(Exception ee) {
         //my message here
    }
}

so in my controllerA I just load the table with setCellValueFactory , that's its all.

use Illuminate\Support\Facades\Hash;
if(Hash::check($plain-text,$hashed-text))
    {
       return true;
    }
    else
    {
        return false;
    }

eg- $plain-text = 'text'; $hashed-text=Hash::make('text');

If your backgrounds are in the drawable folder right now try moving the images from drawable to drawable-nodpi folder in your project. This worked for me, seems that else the images are rescaled by them self..

Looking for EventHandling, ActionListener?

or code?

JButton b = new JButton("Clear");
b.addActionListener(new ActionListener(){
    public void actionPerformed(ActionEvent e){
        textfield.setText("");
        //textfield.setText(null); //or use this
    }
});

Upgrading from Kepler to Luna worked for me.

I had just added some components for Java 1.8 support. It seems that they where not as compatible as I would like or that I mixed the wrong ones. It really caused a lot of problems. Trying to update the system reported errors as they couldn't fulfill some dependencies. Maven upgrades didn't work. Tried a lot of things.

So, if there is no reason to avoid the upgrade just add the luna repository to avalilable software sites (Luna http://download.eclipse.org/releases/luna/ ) and "check for updates". It is better to have all the components with the same version and there are some nice new features.

First, it usually does not matter that much in practice. Most hash functions are "good enough".

But if you really care, you should know that it is a research subject by itself. There are thousand of papers about that. You can still get a PhD today by studying & designing hashing algorithms.

Your second hash function might be slightly better, because it probably should separate the string "ab" from the string "ba". On the other hand, it is probably less quick than the first hash function. It may, or may not, be relevant for your application.

I'll guess that hash functions used for genome strings are quite different than those used to hash family names in telephone databases. Perhaps even some string hash functions are better suited for German, than for English or French words.

Many software libraries give you good enough hash functions, e.g. Qt has qhash, and C++11 has std::hash in <functional>, Glib has several hash functions in C, and POCO has some hash function.

I quite often have hashing functions involving primes (see Bézout's identity) and xor, like e.g.

#define A 54059 /* a prime */
#define B 76963 /* another prime */
#define C 86969 /* yet another prime */
#define FIRSTH 37 /* also prime */
unsigned hash_str(const char* s)
{
   unsigned h = FIRSTH;
   while (*s) {
     h = (h * A) ^ (s[0] * B);
     s++;
   }
   return h; // or return h % C;
}

But I don't claim to be an hash expert. Of course, the values of A, B, C, FIRSTH should preferably be primes, but you could have chosen other prime numbers.

Look at some MD5 implementation to get a feeling of what hash functions can be.

Most good books on algorithmics have at least a whole chapter dedicated to hashing. Start with wikipages on hash function & hash table.

If you know the height, you can use absolute positioning with a negative margin-top like so:

#Login {
    width:400px;
    height:400px;
    position:absolute;
    top:50%;
    left:50%;
    margin-left:-200px; /* width / -2 */
    margin-top:-200px; /* height / -2 */
}

Otherwise, there's no real way to vertically center a div with just CSS

You also need to check Action_Down or Action_UP event. If you will not check then onKey() Method will call 2 times.

getView().setFocusableInTouchMode(true);
getView().requestFocus();

getView().setOnKeyListener(new OnKeyListener() {
        @Override
        public boolean onKey(View v, int keyCode, KeyEvent event) {
                if (event.getAction() == KeyEvent.ACTION_DOWN) {
                    if (keyCode == KeyEvent.KEYCODE_BACK) {
                        Toast.makeText(getActivity(), "Back Pressed", Toast.LENGTH_SHORT).show();
                    return true;
                    }
                }
                return false;
            }
        });

Working very well for me.

The above answers really helped, but only delivered part of the solution. The major issue is that as soon as you remove the Default value attribute, the constraint on the column in database won't be removed. So previous default value will still stay in the database.

Here is a full solution to the problem, including removal of SQL constraints on attribute removal. I am also re-using .NET Framework's native DefaultValue attribute.

Usage

[DatabaseGenerated(DatabaseGeneratedOption.Computed)]
[DefaultValue("getutcdate()")]
public DateTime CreatedOn { get; set; }

For this to work you need to update IdentityModels.cs and Configuration.cs files

IdentityModels.cs file

Add/update this method in your ApplicationDbContext class

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
            base.OnModelCreating(modelBuilder);
            var convention = new AttributeToColumnAnnotationConvention<DefaultValueAttribute, string>("SqlDefaultValue", (p, attributes) => attributes.SingleOrDefault().Value.ToString());
            modelBuilder.Conventions.Add(convention);
}

Configuration.cs file

Update your Configuration class constructor by registering custom Sql generator, like this:

internal sealed class Configuration : DbMigrationsConfiguration<ApplicationDbContext>
{
    public Configuration()
    {
        // DefaultValue Sql Generator
        SetSqlGenerator("System.Data.SqlClient", new DefaultValueSqlServerMigrationSqlGenerator());
    }
}

Next, add custom Sql generator class (you can add it to the Configuration.cs file or a separate file)

internal class DefaultValueSqlServerMigrationSqlGenerator : SqlServerMigrationSqlGenerator
{
    private int dropConstraintCount;

    protected override void Generate(AddColumnOperation addColumnOperation)
    {
        SetAnnotatedColumn(addColumnOperation.Column, addColumnOperation.Table);
        base.Generate(addColumnOperation);
    }

    protected override void Generate(AlterColumnOperation alterColumnOperation)
    {
        SetAnnotatedColumn(alterColumnOperation.Column, alterColumnOperation.Table);
        base.Generate(alterColumnOperation);
    }

    protected override void Generate(CreateTableOperation createTableOperation)
    {
        SetAnnotatedColumns(createTableOperation.Columns, createTableOperation.Name);
        base.Generate(createTableOperation);
    }

    protected override void Generate(AlterTableOperation alterTableOperation)
    {
        SetAnnotatedColumns(alterTableOperation.Columns, alterTableOperation.Name);
        base.Generate(alterTableOperation);
    }

    private void SetAnnotatedColumn(ColumnModel column, string tableName)
    {
        if (column.Annotations.TryGetValue("SqlDefaultValue", out var values))
        {
            if (values.NewValue == null)
            {
                column.DefaultValueSql = null;
                using var writer = Writer();

                // Drop Constraint
                writer.WriteLine(GetSqlDropConstraintQuery(tableName, column.Name));
                Statement(writer);
            }
            else
            {
                column.DefaultValueSql = (string)values.NewValue;
            }
        }
    }

    private void SetAnnotatedColumns(IEnumerable<ColumnModel> columns, string tableName)
    {
        foreach (var column in columns)
        {
            SetAnnotatedColumn(column, tableName);
        }
    }

    private string GetSqlDropConstraintQuery(string tableName, string columnName)
    {
        var tableNameSplitByDot = tableName.Split('.');
        var tableSchema = tableNameSplitByDot[0];
        var tablePureName = tableNameSplitByDot[1];

        var str = $@"DECLARE @var{dropConstraintCount} nvarchar(128)
SELECT @var{dropConstraintCount} = name
FROM sys.default_constraints
WHERE parent_object_id = object_id(N'{tableSchema}.[{tablePureName}]')
AND col_name(parent_object_id, parent_column_id) = '{columnName}';
IF @var{dropConstraintCount} IS NOT NULL
EXECUTE('ALTER TABLE {tableSchema}.[{tablePureName}] DROP CONSTRAINT [' + @var{dropConstraintCount} + ']')";

        dropConstraintCount++;
        return str;
    }
}

I was able to achieve this using an immediately-invoked function and require statement.

const something = (() => (
  condition ? require('something') : null
))();

if(something) {
  something.doStuff();
}

There newer ways to connect Node.js and C++. Please, loot at Nan.

EDIT The fastest and easiest way is nbind. If you want to write asynchronous add-on you can combine Asyncworker class from nan.

You can also use shorthand for describe as desc for table description.

desc [db_name.]table_name;

or

use db_name;
desc table_name;

You can also use explain for table description.

explain [db_name.]table_name;

See official doc

Your web form shouldn't have all of that markup (like the <html> tag). Since it has a master page, you just start with the content tag. Your aspx page should look like this:

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Default.aspx.vb" Inherits="WebUI._Default" MasterPageFile="~/Site1.Master" %>

<asp:content id="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
   This is the body!
</asp:content>

When you're adding a new aspx page make sure to check "select master page" in the "add new item" dialog.

To check for assignability, you can use the Type.IsAssignableFrom method:

typeof(SomeType).IsAssignableFrom(typeof(Derived))

This will work as you expect for type-equality, inheritance-relationships and interface-implementations but not when you are looking for 'assignability' across explicit / implicit conversion operators.

To check for strict inheritance, you can use Type.IsSubclassOf:

typeof(Derived).IsSubclassOf(typeof(SomeType))

In Java 9+ you can do:

var x = List.of("xyz", "abc");
// 'var' works only for local variables

Java 8 using Stream:

Stream.of("xyz", "abc").collect(Collectors.toList());

And of course, you can create a new object using the constructor that accepts a Collection:

List<String> x = new ArrayList<>(Arrays.asList("xyz", "abc"));

Tip: The docs contains very useful information that usually contains the answer you're looking for. For example, here are the constructors of the ArrayList class:

• ArrayList()

  Constructs an empty list with an initial capacity of ten.

• ArrayList(Collection<? extends E> c) (*)

  Constructs a list containing the elements of the specified collection, in the order they are returned by the collection's iterator.

• ArrayList(int initialCapacity)

  Constructs an empty list with the specified initial capacity.

Something like:

File file = new File("C:\\user\\Desktop\\dir1\\dir2\\filename.txt");
file.getParentFile().mkdirs();
FileWriter writer = new FileWriter(file);

I had the same problem i solved it by only adding remote catalog in eclipse go to Window -> Preferences ->Maven ->Archetypes ->click on add remote Catalog then a window will open in that paste
http://repo.maven.apache.org/maven2/archetype-catalog.xml in that catalog file then hit ok restart eclipse now all working fine

Here's one possible method.

function isMouseInBox(e) {
  var textbox = document.getElementById('textbox');

  // Box position & sizes
  var boxX = textbox.offsetLeft;
  var boxY = textbox.offsetTop;
  var boxWidth = textbox.offsetWidth;
  var boxHeight = textbox.offsetHeight;

  // Mouse position comes from the 'mousemove' event
  var mouseX = e.pageX;
  var mouseY = e.pageY;
  if(mouseX>=boxX && mouseX<=boxX+boxWidth) {
    if(mouseY>=boxY && mouseY<=boxY+boxHeight){
       // Mouse is in the box
       return true;
    }
  }
}

document.addEventListener('mousemove', function(e){
    isMouseInBox(e);
})

You could also try the dateparser module, which may be slower than datefinder on free text but which should cover more potential cases and date formats, as well as a significant number of languages.

Magic commands such as

%matplotlib qt  

work in the iPython console and Notebook, but do not work within a script.

In that case, after importing:

from IPython import get_ipython

use:

get_ipython().run_line_magic('matplotlib', 'inline')

for inline plotting of the following code, and

get_ipython().run_line_magic('matplotlib', 'qt')

for plotting in an external window.

Edit: solution above does not always work, depending on your OS/Spyder version Anaconda issue on GitHub. Setting the Graphics Backend to Automatic (as indicated in another answer: Tools >> Preferences >> IPython console >> Graphics --> Automatic) solves the problem for me.

Then, after a Console restart, one can switch between Inline and External plot windows using the get_ipython() command, without having to restart the console.

you have the print_r function DOC

For me this error occurred because i didn't have UIWindow declared in the upper level of my class when setting a root view controller

            rootViewController?.showTimeoutAlert = showTimeOut
            let navigationController = SwipeNavigationController(rootViewController: rootViewController!)
            self.window = UIWindow(frame: UIScreen.main.bounds)
            self.window?.rootViewController = navigationController
            self.window?.makeKeyAndVisible()

Ex if I tried declaring window in that block of code instead of referencing self then I would receive the error

This is so late, but for the sake of future researchers, I'll post my answer. I believe most of you looking for height : 0 is for the sake of td or tr toggle transition animation or something similar. But it is not possible to make it using just height, max-height, line-height on td or tr, but you can use the following tricks to make it:

• Wrapping all td contents into div and use height: 0 + overflow: hidden + white-space: nowrap on divs , and the animation/transition of your choice
• Use transform: scaleY ( ?° ?? ?°)

I managed to fix this by adding:

android:layout_marginTop="?android:attr/actionBarSize"

to the FrameLayout like so:

 <FrameLayout
        android:id="@+id/content"
        android:layout_marginTop="?android:attr/actionBarSize"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
       />

try execution the following command

vim .bashrc
:set ff=unix
:wq!

Probably, a better and more functional way is to wrap exceptions and propagate them further in the stream. Take a look at the Try type of Vavr for example.

Example:

interface CheckedFunction<I, O> {
    O apply(I i) throws Exception; }

static <I, O> Function<I, O> unchecked(CheckedFunction<I, O> f) {
    return i -> {
        try {
            return f.apply(i);
        } catch(Exception ex) {

            throw new RuntimeException(ex);
        }
    } }

fileNamesToRead.map(unchecked(file -> Files.readAllLines(file)))

OR

@SuppressWarnings("unchecked")
private static <T, E extends Exception> T throwUnchecked(Exception e) throws E {
    throw (E) e;
}

static <I, O> Function<I, O> unchecked(CheckedFunction<I, O> f) {
    return arg -> {
        try {
            return f.apply(arg);
        } catch(Exception ex) {
            return throwUnchecked(ex);
        }
    };
}

2nd implementation avoids wrapping the exception in a RuntimeException. throwUnchecked works because almost always all generic exceptions are treated as unchecked in java.

The most common valid reason for wanting an integer constant associated with each enum value is to interoperate with some other component which still expects those integers (e.g. a serialization protocol which you can't change, or the enums represent columns in a table, etc).

In almost all cases I suggest using an EnumMap instead. It decouples the components more completely, if that was the concern, or if the enums represent column indices or something similar, you can easily make changes later on (or even at runtime if need be).

 private final EnumMap<Page, Integer> pageIndexes = new EnumMap<Page, Integer>(Page.class);
 pageIndexes.put(Page.SIGN_CREATE, 1);
 //etc., ...

 int createIndex = pageIndexes.get(Page.SIGN_CREATE);

It's typically incredibly efficient, too.

Adding data like this to the enum instance itself can be very powerful, but is more often than not abused.

Edit: Just realized Bloch addressed this in Effective Java / 2nd edition, in Item 33: Use EnumMap instead of ordinal indexing.

Use the below code:

import base64

#Taking input through the terminal.
welcomeInput= raw_input("Enter 1 to convert String to Base64, 2 to convert Base64 to String: ") 

if(int(welcomeInput)==1 or int(welcomeInput)==2):
    #Code to Convert String to Base 64.
    if int(welcomeInput)==1:
        inputString= raw_input("Enter the String to be converted to Base64:") 
        base64Value = base64.b64encode(inputString.encode())
        print "Base64 Value = " + base64Value
    #Code to Convert Base 64 to String.
    elif int(welcomeInput)==2:
        inputString= raw_input("Enter the Base64 value to be converted to String:") 
        stringValue = base64.b64decode(inputString).decode('utf-8')
        print "Base64 Value = " + stringValue

else:
    print "Please enter a valid value."

I read all the clunky solutions on the net about how to mask passwords in a batch file, the ones from using a hide.com solution and even the ones that make the text and the background the same color. The hide.com solution works decent, it isn't very secure, and it doesn't work in 64-bit Windows. So anyway, using 100% Microsoft utilities, there is a way!

First, let me explain my use. I have about 20 workstations that auto logon to Windows. They have one shortcut on their desktop - to a clinical application. The machines are locked down, they can't right click, they can't do anything but access the one shortcut on their desktop. Sometimes it is necessary for a technician to kick up some debug applications, browse windows explorer and look at log files without logging the autolog user account off.

So here is what I have done.

Do it however you wish, but I put my two batch files on a network share that the locked down computer has access to.

My solution utilizes 1 main component of Windows - runas. Put a shortcut on the clients to the runas.bat you are about to create. FYI, on my clients I renamed the shortcut for better viewing purposes and changed the icon.

You will need to create two batch files.

I named the batch files runas.bat and Debug Support.bat

runas.bat contains the following code:

You can add as many if "%un%" and if not "%un%" for all the users you want to give access to. The @ping is my coonass way of making a seconds timer.

So that takes care of the first batch file - pretty simple eh?

Here is the code for Debug Support.bat:

cls
@echo off
TITLE SUPPORT UTILITIES
goto menu

:menu
cls
@echo %username%
echo.
echo           .....................................
echo            ~Written by Cajun Wonder 4/1/2010~
echo           .....................................
echo.
echo What do you want to do? 
echo.
echo [1]  Launch notepad
echo.

:choice
set /P C=[Option]? 
if "%C%"=="1" goto notepad
goto choice

:notepad
echo.
@echo starting notepad....
@ping -n 3 127.0.0.1 > NUL
start notepad
cls
goto menu

I'm not a coder and really just started getting into batch scripting about a year ago, and this round about way that I discovered of masking a password in a batch file is pretty awesome!

I hope to hear that someone other than me is able to get some use out of it!

I managed to regenerate R: File->Settings->Compiler

then UNCHECK "Use in-process build"

Rebuild Project

just use javascript:---- exemplale

javascript:var JFL_81371678974472 = new JotformFeedback({ formId: '81371678974472', base: 'https://form.jotform.me/', windowTitle: 'Photobook Series', background: '#e44c2a', fontColor: '#FFFFFF', type: 'false', height: 700, width: 500, openOnLoad: true })

You should always write command after a Tab and not white space.

This applies to gcc line (line #4) in your case. You need to insert tab before gcc.

Also replace \rm -fr ll with rm -fr ll. Insert tabs before this command too.

Generally speaking:

F5 may give you the same page even if the content is changed, because it may load the page from cache. But Ctrl-F5 forces a cache refresh, and will guarantee that if the content is changed, you will get the new content.

You sure the timer isn't outliving the 'dbiSchedule' somehow and firing after the 'dbiSchedule' has been been disposed of?

If that is the case you might be able to recreate it more consistently if the timer fires more quickly thus increasing the chances of you closing the Form just as the timer is firing.

This is probably what you're looking for in terms of thread safety & "prettyness" when trying to consume everything in the queue:

for (YourObject obj = queue.poll(); obj != null; obj = queue.poll()) {
}

This will guarantee that you quit when the queue is empty, and that you continue to pop objects off of it as long as it's not empty.

You need to use backtick instead of single quotes:

Single quote - 'Business Name' - Wrong

Backtick - `Business Name` - Correct

This may help you!

$latlng='{"lat":29.5345741,"lng":75.0342196}';

The best approach for you to communicate between the two controllers is to use events.

Scope Documentation

In this check out $on, $broadcast and $emit.

In general use case the usage of angular.element(catapp).scope() was designed for use outside the angular controllers, like within jquery events.

Ideally in your usage you would write an event in controller 1 as:

$scope.$on("myEvent", function (event, args) {
   $scope.rest_id = args.username;
   $scope.getMainCategories();
});

And in the second controller you'd just do

$scope.initRestId = function(){
   $scope.$broadcast("myEvent", {username: $scope.user.username });
};

Edit: Realised it was communication between two modules

Can you try including the firstApp module as a dependency to the secondApp where you declare the angular.module. That way you can communicate to the other app.

document.getElementById('one').innerText;
alert(content);

It does not print the value; But, if done this way

document.getElementById('one').value;
alert(content);

User-specific settings should be written to HKCU\Software, machine-specific settings to HKLM\Software. Under these keys, structure [software vendor name]\[application name] (e.g. HKLM\Software\Microsoft\Internet Explorer) may be the most common, but that's just a convention, not a law of nature.

Many (most?) applications also add their uninstall entries to HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\[app name], but again, not all applications do this.

These are the most important keys; however, contents of the registry do not have to represent the installed software exactly - maybe the application was installed once, but then was manually deleted, or maybe the uninstaller didn't remove all traces of it. If you want to be sure, check the filesystem to see if the application still exists where its registry entries say it is.

Edit:

If you're a member of the group Administrators, you can check the HKEY_USERS hive - each user's HKCU actually resides there (you'll need to know the user SID, or go through all of them).

Note: As @Brian Ensink says, "installed" is a bit of a vague concept - are we trying to find what the user could run? Some software doesn't even write to the Registry at all: search for "portable apps" to see apps that have been specifically modified to run directly from media (CD/USB) and not to leave any traces on the computer. We may also have to scan the disks, and network disks, and anything the user downloads, and world-accessible Windows shares in the Internet (yes, such things exist legitimately - \\live.sysinternals.com\tools comes to mind). In this direction, there's no real limit of what the user can run, unless prevented by system policies.

You might want to take a look at the excellent HTTP Python library called Requests. It makes every task involving HTTP a bit easier than urllib2. From Cookies section of quickstart guide:

To send your own cookies to the server, you can use the cookies parameter:

>>> cookies = dict(cookies_are='working')

>>> r = requests.get('http://httpbin.org/cookies', cookies=cookies)
>>> r.text
'{"cookies": {"cookies_are": "working"}}'

Stacks for threads are often smaller. You can change the default at link time, or change at run time also. For reference, some defaults are:

• glibc i386, x86_64: 7.4 MB
• Tru64 5.1: 5.2 MB
• Cygwin: 1.8 MB
• Solaris 7..10: 1 MB
• MacOS X 10.5: 460 KB
• AIX 5: 98 KB
• OpenBSD 4.0: 64 KB
• HP-UX 11: 16 KB

Open the Console view, locate the console for your running app and hit the Big Red Button.

Alternatively if you open the Debug perspective you will see all running apps in (by default) the top left. You can select the one that's causing you grief and once again hit the Big Red Button.

• Just for another example of Scanner.next() and nextLine() is that like below : nextLine() does not let user type while next() makes Scanner wait and read the input.

   Scanner sc = new Scanner(System.in);
  
   do {
      System.out.println("The values on dice are :");
      for(int i = 0; i < n; i++) {
          System.out.println(ran.nextInt(6) + 1);
      }
      System.out.println("Continue : yes or no");
   } while(sc.next().equals("yes"));
  // while(sc.nextLine().equals("yes"));
  

To do this for a specific target, you can do the following:

target_compile_definitions(my_target PRIVATE FOO=1 BAR=1)

You should do this if you have more than one target that you're building and you don't want them all to use the same flags. Also see the official documentation on target_compile_definitions.

To convert a string to json and the sting is like json. {"phonetype":"N95","cat":"WP"}

String Data=response.getEntity().getText().toString(); // reading the string value 
JSONObject json = (JSONObject) new JSONParser().parse(Data);
String x=(String) json.get("phonetype");
System.out.println("Check Data"+x);
String y=(String) json.get("cat");
System.out.println("Check Data"+y);

For match_parent you can use

SizedBox(
  width: double.infinity, // match_parent
  child: RaisedButton(...)
)

For any particular value you can use

SizedBox(
  width: 100, // specific value
  child: RaisedButton(...)
)

$('.abc[checked!=true]').length == 0

Had this problem when setting up a new slave server. Found it was the slave server IP address was missing from the master server /etc/hosts.allow file. Added the IP address and it let me connect to the master server.

Note that I use hosts.allow and hosts.deny to control access.

I know I'm coming at this years later, but I can't believe no one suggested usermod.

usermod --password `perl -e "print crypt('password','sa');"` root

Hell, just in case someone wants to do this on an older HPUX you can use usermod.sam.

/usr/sam/lbin/usermod.sam -F -p `perl -e "print crypt('password','sa');"` username

The -F is only needed if the person executing the script is the current user. Of course you don't need to use Perl to create the hash. You could use openssl or many other commands in its place.

This can also be due to the build check box not being ticked for the current platform project in the build configuration. Click Build | Configuration manager, then make sure the test projects have a tick in the build column for the platform that you're using (for example 'x86').

This was definitely the solution that worked for me.

I'm quite sure you won't get this 32Bit DLL working in Office 64Bit. The DLL needs to be updated by the author to be compatible with 64Bit versions of Office.

The code changes you have found and supplied in the question are used to convert calls to APIs that have already been rewritten for Office 64Bit. (Most Windows APIs have been updated.)

From: http://technet.microsoft.com/en-us/library/ee681792.aspx:

"ActiveX controls and add-in (COM) DLLs (dynamic link libraries) that were written for 32-bit Office will not work in a 64-bit process."

Edit: Further to your comment, I've tried the 64Bit DLL version on Win 8 64Bit with Office 2010 64Bit. Since you are using User Defined Functions called from the Excel worksheet you are not able to see the error thrown by Excel and just end up with the #VALUE returned.

If we create a custom procedure within VBA and try one of the DLL functions we see the exact error thrown. I tried a simple function of swe_day_of_week which just has a time as an input and I get the error Run-time error '48' File not found: swedll32.dll.

Now I have the 64Bit DLL you supplied in the correct locations so it should be found which suggests it has dependencies which cannot be located as per https://stackoverflow.com/a/8607250/1733206

I've got all the .NET frameworks installed which would be my first guess, so without further information from the author it might be difficult to find the problem.

Edit2: And after a bit more investigating it appears the 64Bit version you have supplied is actually a 32Bit version. Hence the error message on the 64Bit Office. You can check this by trying to access the '64Bit' version in Office 32Bit.

You will eventually be able to use

background-image: attr(data-image-src url);

but that is not implemented anywhere yet to my knowledge. In the above, url is an optional "type-or-unit" parameter to attr(). See https://drafts.csswg.org/css-values/#attr-notation.

This should do:

Assembly assem = Assembly.GetExecutingAssembly();
AssemblyName aName = assem.GetName();
return aName.Version.ToString();

@Amber gave correct answer! Just one more addition, if you do not know the exact path of the file you can use wildcards! This worked for me.

git log --all -- **/thefile.*

import java.util.Random;

public class passGen{
    // Version 1.0
    private static final String dCase = "abcdefghijklmnopqrstuvwxyz";
    private static final String uCase = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
    private static final String sChar = "!@#$%^&*";
    private static final String intChar = "0123456789";
    private static Random r = new Random();
    private static StringBuilder pass = new StringBuilder();

    public static void main (String[] args) {
        System.out.println ("Generating pass...");
        while (pass.length () != 16){
            int rPick = r.nextInt(4);
            if (rPick == 0){
                int spot = r.nextInt(26);
                pass.append(dCase.charAt(spot));
            } else if (rPick == 1) {
                int spot = r.nextInt(26);
                pass.append(uCase.charAt(spot));
            } else if (rPick == 2) {
                int spot = r.nextInt(8);
                pass.append(sChar.charAt(spot));
            } else {
                int spot = r.nextInt(10);
                pass.append(intChar.charAt(spot));
            }
        }
        System.out.println ("Generated Pass: " + pass.toString());
    }
}

This just adds the password into the string and... yeah, it works well. Check it out... It is very simple; I wrote it.

You can use class(x) to check the variable type. If requirement is to check all variables type of a data frame then sapply(x, class) can be used.

Also, if you have a variable,

CabRes::where('m_Id', 46)
      ->where('t_Id', 2)
      ->where(function($q) use ($variable){
          $q->where('Cab', 2)
            ->orWhere('Cab', $variable);
      })
      ->get();

You can take a look at this article. This is a well-documented example for calculating correlation based on historical forex currency pairs data from multiple files using pandas library (for Python), and then generating a heatmap plot using seaborn library.

In a PRE tag -and in most other HTML tags- plain text for a batch file that uses the output redirection characters (< and >) will break the HTML, but here is my tip: anything goes in a TEXTAREA element -it will not break the HTML, mainly because we are inside a control instanced and handled by the OS, and therefore its content are not being parsed by the HTML engine.

As an example, say I want to highlight the syntax of my batch file using javascript. I simply paste the code in a textarea without worrying about the HTML reserved characters, and have the script process the innerHTML property of the textarea, which evaluates to the text with the HTML reserved characters replaced by their corresponding ISO-8859-1 entities.

Browsers will escape special characters automatically when you retrieve the innerHTML (and outerHTML) property of an element. Using a textarea (and who knows, maybe an input of type text) just saves you from doing the conversion (manually or through code).

I use this trick to test my syntax highlighter, and when I'm done authoring and testing, I simply hide the textarea from view.

You can also get the last command from history and subtract its EndExecutionTime from its StartExecutionTime.

.\do_something.ps1  
$command = Get-History -Count 1  
$command.EndExecutionTime - $command.StartExecutionTime

you can also just change your delete to a select *

and test your selection

the records selected will be the same as the ones deleted

you can also wrap your statement in a begin / rollback if you are not sure - test the statement then if all is good remove rollback

for example

SELECT * FROM table WHERE id BETWEEN 79 AND 296

will show all the records matching the where if they are the wants you 'really' want to delete then use

DELETE FROM table WHERE id BETWEEN 79 AND 296

You can also create a trigger / which catches deletes and puts them into a history table

so if you delete something by mistake you can always get it back

(keep your history table records no older than say 6 months or whatever business rules say)

If you are using ATL/MFC CString, simply call CString::MakeReverse().

With current version of Angular Material (6.4.7) you can use a custom class:

let dialogRef = dialog.open(UserProfileComponent, {
  panelClass: 'my-class'
});

Now put your class somewhere global (haven't been able to make this work elsewhere), e.g. in styles.css:

.my-class .mat-dialog-container{
  height: 400px;
  width: 600px;
  border-radius: 10px;
  background: lightcyan;
  color: #039be5;
}

Done!

You are propably pasting them directly into a query. Istead you should "escape" them, using appriopriate function - mysql_real_escape_string, mysqli_real_escape_string or PDO::quote depending on extension you are using.

we can use data.table library

  library(data.table)
  expr <- data.table(expr)
  expr[cell_type == "hesc"]
  expr[cell_type %in% c("hesc","fibroblast")]

or filter using %like% operator for pattern matching

 expr[cell_type %like% "hesc"|cell_type %like% "fibroblast"]

                    ((RichTextBox)sender).AppendText("Place Holder");
                }
            }
        }
}

Both C++ and C# are missing easy ways to create a new type which is semantically identical to an exisiting type. I find such 'typedefs' totally essential for type-safe programming and its a real shame c# doesn't have them built-in. The difference between void f(string connectionID, string username) to void f(ConID connectionID, UserName username) is obvious ...

(You can achieve something similar in C++ with boost in BOOST_STRONG_TYPEDEF)

It may be tempting to use inheritance but that has some major limitations:

• it will not work for primitive types
• the derived type can still be casted to the original type, ie we can send it to a function receiving our original type, this defeats the whole purpose
• we cannot derive from sealed classes (and ie many .NET classes are sealed)

The only way to achieve a similar thing in C# is by composing our type in a new class:

Class SomeType { 
  public void Method() { .. }
}

sealed Class SomeTypeTypeDef {
  public SomeTypeTypeDef(SomeType composed) { this.Composed = composed; }

  private SomeType Composed { get; }

  public override string ToString() => Composed.ToString();
  public override int GetHashCode() => HashCode.Combine(Composed);
  public override bool Equals(object obj) => obj is TDerived o && Composed.Equals(o.Composed); 
  public bool Equals(SomeTypeTypeDefo) => object.Equals(this, o);

  // proxy the methods we want
  public void Method() => Composed.Method();
}

While this will work it is very verbose for just a typedef. In addition we have a problem with serializing (ie to Json) as we want to serialize the class through its Composed property.

Below is a helper class that uses the "Curiously Recurring Template Pattern" to make this much simpler:

namespace Typedef {

  [JsonConverter(typeof(JsonCompositionConverter))]
  public abstract class Composer<TDerived, T> : IEquatable<TDerived> where TDerived : Composer<TDerived, T> {
    protected Composer(T composed) { this.Composed = composed; }
    protected Composer(TDerived d) { this.Composed = d.Composed; }

    protected T Composed { get; }

    public override string ToString() => Composed.ToString();
    public override int GetHashCode() => HashCode.Combine(Composed);
    public override bool Equals(object obj) => obj is Composer<TDerived, T> o && Composed.Equals(o.Composed); 
    public bool Equals(TDerived o) => object.Equals(this, o);
  }

  class JsonCompositionConverter : JsonConverter {
    static FieldInfo GetCompositorField(Type t) {
      var fields = t.BaseType.GetFields(BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.FlattenHierarchy);
      if (fields.Length!=1) throw new JsonSerializationException();
      return fields[0];
    }

    public override bool CanConvert(Type t) {
      var fields = t.GetFields(BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.FlattenHierarchy);
      return fields.Length == 1;
    }

    // assumes Compositor<T> has either a constructor accepting T or an empty constructor
    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer) {
      while (reader.TokenType == JsonToken.Comment && reader.Read()) { };
      if (reader.TokenType == JsonToken.Null) return null; 
      var compositorField = GetCompositorField(objectType);
      var compositorType = compositorField.FieldType;
      var compositorValue = serializer.Deserialize(reader, compositorType);
      var ctorT = objectType.GetConstructor(new Type[] { compositorType });
      if (!(ctorT is null)) return Activator.CreateInstance(objectType, compositorValue);
      var ctorEmpty = objectType.GetConstructor(new Type[] { });
      if (ctorEmpty is null) throw new JsonSerializationException();
      var res = Activator.CreateInstance(objectType);
      compositorField.SetValue(res, compositorValue);
      return res;
    }

    public override void WriteJson(JsonWriter writer, object o, JsonSerializer serializer) {
      var compositorField = GetCompositorField(o.GetType());
      var value = compositorField.GetValue(o);
      serializer.Serialize(writer, value);
    }
  }

}

With Composer the above class becomes simply:

sealed Class SomeTypeTypeDef : Composer<SomeTypeTypeDef, SomeType> {
   public SomeTypeTypeDef(SomeType composed) : base(composed) {}

   // proxy the methods we want
   public void Method() => Composed.Method();
}

And in addition the SomeTypeTypeDef will serialize to Json in the same way that SomeType does.

Hope this helps !

For this your android application must have uploaded into the android market. when you upload it on the android market then use the following code to open the market with your android application.

    Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("market://details?id=<packagename>"));
startActivity(intent);

If you want it to download and install from your own server then use the following code

Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("http://www.example.com/sample/test.apk"));
    startActivity(intent);

Servlets are the server side java programs which execute inside the web container. The main goal of the servlet is to process the requests received from the client.

Java Server Pages is used to create dynamic web pages. Jsp's were introduced to write java plus html code in a single file which was not easy to do in servlets program. And a jsp file is converted to a java servlet when it is translated.

Java Server Faces is a MVC web framework which simplifies the development of UI.

cout << text << i;

The << operator for ostream returns a reference to the ostream, so you can just keep chaining the << operations. That is, the above is basically the same as:

cout << text;
cout << i;

In addition to what eugene and stevenl posted, you might encounter problems with using both <> and <STDIN> in one script: <> iterates through (=concatenating) all files given as command line arguments.

However, should a user ever forget to specify a file on the command line, it will read from STDIN, and your code will wait forever on input

GRANT SELECT ON *.* TO 'user'@'localhost' IDENTIFIED BY 'password';

This will create a user with SELECT privilege for all database including Views.

This is absolutely possible. Although you shouldn't do it unless you know what you are dealing with. Took me about 2 days to figure it out. Here is a stored procedure where i enter: ---database name (schema name is "_" for readability) ---table name ---column ---column data type (column added is always null, otherwise you won't be able to insert) ---the position of the new column.

Since I'm working with tables from SAM toolkit (and some of them have > 80 columns) , the typical variable won't be able to contain the query. That forces the need of external file. Now be careful where you store that file and who has access on NTFS and network level.

Cheers!

Erm, can you not just use Settings.Default.Reset() to restore your default settings?

The code above works perfectly with one minor flaw; the resulting file is not saved with a .csv extension. – Tensigh 2 days ago

I added the following to code and it saved my file as a csv. Thanks for this bit of code.It all worked as expected.

ActiveWorkbook.SaveAs Filename:=SaveToDirectory & ThisWorkbook.Name & "-" & WS.Name & ".csv", FileFormat:=xlCSV

we can use MutationObserver to solve the problem in efficient way adding a sample code below

<!DOCTYPE html>
<html>
<head>
    <title></title>
    <style>
        #second{
            position: absolute;
            width: 100px;
            height: 100px;
            background-color: #a1a1a1;
        }
    </style>
</head>
<body>
<div id="first"></div>
<script>
    var callthis = function(element){
           element.setAttribute("tabIndex",0);
        element.focus();
        element.onkeydown = handler;
        function handler(){
                alert("called")
        }
    }


    var observer = new WebKitMutationObserver(function(mutations) {
        mutations.forEach(function(mutation) {
            for (var i = 0; i < mutation.addedNodes.length; i++)
            if(mutation.addedNodes[i].id === "second"){
                callthis(mutation.addedNodes[i]);
            }

        })
    });
    observer.observe(document.getElementById("first"), { childList: true });


    var ele = document.createElement('div');
    ele.id = "second"

    document.getElementById("first").appendChild(ele);

</script>

</body>
</html>

I try like this with function then calling if needed a this function. Has been worked for me.

function modal_fix() {
var a = $(".modal"),
    b = $("body");
a.on("shown.bs.modal", function () {
    b.hasClass("modal-open") || b.addClass("modal-open");
});
}

Here is my solution:

<!-- jquery smooth scroll to id's -->   
<script>
$(function() {
  $('a[href*=\\#]:not([href=\\#])').click(function() {
    if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
      var target = $(this.hash);
      target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
      if (target.length) {
        $('html,body').animate({
          scrollTop: target.offset().top
        }, 500);
        return false;
      }
    }
  });
});
</script>

With just this snippet you can use an unlimited number of hash-links and corresponding ids without having to execute a new script for each.

I already explained how it works in another thread here: https://stackoverflow.com/a/28631803/4566435 (or here's a direct link to my blog post)

Try Using DateTime::createFromFormat

$date = DateTime::createFromFormat('d/m/Y', "24/04/2012");
echo $date->format('Y-m-d');

Output

2012-04-24

EDIT:

If the date is 5/4/2010 (both D/M/YYYY or DD/MM/YYYY), this below method is used to convert 5/4/2010 to 2010-4-5 (both YYYY-MM-DD or YYYY-M-D) format.

$old_date = explode('/', '5/4/2010'); 
$new_data = $old_date[2].'-'.$old_date[1].'-'.$old_date[0];

OUTPUT:

2010-4-5

CCS only

@media (max-width: 1024px) and (orientation: portrait){ /* tablet and smaller */
  body:after{
    position: absolute;
    z-index: 9999;
    width: 100%;
    top: 0;
    bottom: 0;
    content: "";
    background: #212121 url(http://i.stack.imgur.com/sValK.png) 0 0 no-repeat; /* replace with an image that tells the visitor to rotate the device to landscape mode */
    background-size: 100% auto;
    opacity: 0.95;
  }
}

In some cases you may want to add a small piece of code to reload to page after the visitor rotated the device, so that the CSS is rendered properly:

window.onorientationchange = function() { 
    var orientation = window.orientation; 
        switch(orientation) { 
            case 0:
            case 90:
            case -90: window.location.reload(); 
            break; } 
};

In atan2, the output is: -pi < atan2(y,x) <pi
and in atan, the output is: -pi/2 < atan(y/x) < pi/2 //it dose NOT consider the quarter.
If you want to get the orientation between 0 and 2*pi (like the high-school math), we need to use the atan2 and for negative values add the 2*pi to get the final result between 0 and 2*pi.
Here is the Java source code to explain it clearly:

System.out.println(Math.atan2(1,1)); //pi/4 in the 1st quarter
System.out.println(Math.atan2(1,-1)); //(pi/4)+(pi/2)=3*(pi/4) in the 2nd quarter

System.out.println(Math.atan2(-1,-1 ));//-3*(pi/4) and it is less than 0.
System.out.println(Math.atan2(-1,-1)+2*Math.PI); //5(pi/4) in the 3rd quarter

System.out.println(Math.atan2(-1,1 ));//-pi/4 and it is less than 0.
System.out.println(Math.atan2(-1,1)+2*Math.PI); //7*(pi/4) in the 4th quarter

System.out.println(Math.atan(1 ));//pi/4
System.out.println(Math.atan(-1 ));//-pi/4

this.HttpContext.Response.StatusCode = 418; // I'm a teapot

How to end the request?

Try other solution, just:

return StatusCode(418);

You could use StatusCode(???) to return any HTTP status code.

Also, you can use dedicated results:

Success:

• return Ok() ? Http status code 200
• return Created() ? Http status code 201
• return NoContent(); ? Http status code 204

Client Error:

• return BadRequest(); ? Http status code 400
• return Unauthorized(); ? Http status code 401
• return NotFound(); ? Http status code 404

import pandas as pd
import numpy as np

df = pd.DataFrame({'ItemQty': {0: 3, 1: 25}, 
                   'Seatblocks': {0: '2:218:10:4,6', 1: '1:13:36:1,12 1:13:37:1,13'}, 
                   'ItemExt': {0: 60, 1: 300}, 
                   'CustomerName': {0: 'McCartney, Paul', 1: 'Lennon, John'}, 
                   'CustNum': {0: 32363, 1: 31316}, 
                   'Item': {0: 'F04', 1: 'F01'}}, 
                    columns=['CustNum','CustomerName','ItemQty','Item','Seatblocks','ItemExt'])

print (df)
   CustNum     CustomerName  ItemQty Item                 Seatblocks  ItemExt
0    32363  McCartney, Paul        3  F04               2:218:10:4,6       60

Another similar solution with chaining is use reset_index and rename:

print (df.drop('Seatblocks', axis=1)
             .join
             (
             df.Seatblocks
             .str
             .split(expand=True)
             .stack()
             .reset_index(drop=True, level=1)
             .rename('Seatblocks')           
             ))

   CustNum     CustomerName  ItemQty Item  ItemExt    Seatblocks
0    32363  McCartney, Paul        3  F04       60  2:218:10:4,6
1    31316     Lennon, John       25  F01      300  1:13:36:1,12
1    31316     Lennon, John       25  F01      300  1:13:37:1,13

If in column are NOT NaN values, the fastest solution is use list comprehension with DataFrame constructor:

df = pd.DataFrame(['a b c']*100000, columns=['col'])

In [141]: %timeit (pd.DataFrame(dict(zip(range(3), [df['col'].apply(lambda x : x.split(' ')[i]) for i in range(3)]))))
1 loop, best of 3: 211 ms per loop

In [142]: %timeit (pd.DataFrame(df.col.str.split().tolist()))
10 loops, best of 3: 87.8 ms per loop

In [143]: %timeit (pd.DataFrame(list(df.col.str.split())))
10 loops, best of 3: 86.1 ms per loop

In [144]: %timeit (df.col.str.split(expand=True))
10 loops, best of 3: 156 ms per loop

In [145]: %timeit (pd.DataFrame([ x.split() for x in df['col'].tolist()]))
10 loops, best of 3: 54.1 ms per loop

But if column contains NaN only works str.split with parameter expand=True which return DataFrame (documentation), and it explain why it is slowier:

df = pd.DataFrame(['a b c']*10, columns=['col'])
df.loc[0] = np.nan
print (df.head())
     col
0    NaN
1  a b c
2  a b c
3  a b c
4  a b c

print (df.col.str.split(expand=True))
     0     1     2
0  NaN  None  None
1    a     b     c
2    a     b     c
3    a     b     c
4    a     b     c
5    a     b     c
6    a     b     c
7    a     b     c
8    a     b     c
9    a     b     c

if you just want to save and load a list try Pickle

Pickle saving:

with open("yourFile","wb")as file:
 pickle.dump(YourList,file)

and loading:

with open("yourFile","rb")as file:
 YourList=pickle.load(file)

Just use ojdb6.jar and will fix all such issues.

For maven based applications:

1. Download and copy ojdbc6.jar to a directory in your local machine

2. From the location where you have copied your jar install the ojdbc6.jar in your local .M2 Repo by issuing below command C:\SRK\Softwares\Libraries>mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0.3 -Dpackaging=jar -Dfile=ojdbc6.jar -DgeneratePom=true

3. Add the below in your project pom.xml as ojdbc6.jar dependency

   <dependency>
       <groupId>com.oracle</groupId>
       <artifactId>ojdbc6</artifactId>
       <version>11.2.0.3</version>
   </dependency>
   

PS: The issue might be due to uses of @Lob annotation in JPA for storing large objects specifically in oracle db columns. Upgrading to 11.2.0.3 (ojdbc6.jar) can resolve the issue.

html, body {
    min-height: 100%;
}

Will do the trick.

By default, even html and body are only as big as the content they hold, but never more than the width/height of the windows. This can often lead to quite strange results.

if (theDialog.ShowDialog() == DialogResult.OK)
{
    try
    {
        if ((myStream = theDialog.OpenFile()) != null)
        {
            using (myStream)
            {
                // Insert code to read the stream here.
            }
        }
    }
    catch (Exception ex)

The term "clone" is ambiguous (though the Java class library includes a Cloneable interface) and can refer to a deep copy or a shallow copy. Deep/shallow copies are not specifically tied to Java but are a general concept relating to making a copy of an object, and refers to how members of an object are also copied.

As an example, let's say you have a person class:

class Person {
    String name;
    List<String> emailAddresses
}

How do you clone objects of this class? If you are performing a shallow copy, you might copy name and put a reference to emailAddresses in the new object. But if you modified the contents of the emailAddresses list, you would be modifying the list in both copies (since that's how object references work).

A deep copy would mean that you recursively copy every member, so you would need to create a new List for the new Person, and then copy the contents from the old to the new object.

Although the above example is trivial, the differences between deep and shallow copies are significant and have a major impact on any application, especially if you are trying to devise a generic clone method in advance, without knowing how someone might use it later. There are times when you need deep or shallow semantics, or some hybrid where you deep copy some members but not others.

I used to have this problem sometimes, the solution was to change the USB cable to a new one

Here's another way to plot the data, involves turning the date_time into an index, this might help you for future slicing

#convert column to datetime
trip_data['lpep_pickup_datetime'] = pd.to_datetime(trip_data['lpep_pickup_datetime'])
#turn the datetime to an index
trip_data.index = trip_data['lpep_pickup_datetime']
#Plot
trip_data['Trip_distance'].plot(kind='hist')
plt.show()

I'm looking for a solution for some time but I can not solve my problem. I tried several solutions in stackoverflow.com but no this helping me.

i had pandas installed ('conda list|grep pandas') and python could find it ('python; import imp; imp.find_module("pandas");'

However still was getting this error inside spyder. I had accidentally been using 'spyder3' instead of 'spyder' command, the former using a different python (3.5) rather than one conda is using (3.8). Running spyder and things worked as expected.

I found this approach relatively easy.

Checkout to the branch and than

1. Run

   git rev-list --simplify-by-decoration -2 HEAD
   

This will provide just two SHAs:

1) last commit of the branch [C1]

2) and commit parent to the first commit of the branch [C2]

2. Now run

   git log --decorate --pretty=oneline --reverse --name-status <C2>..<C1>
   

Here C1 and C2 are two strings you will get when you run first command. Put these values without <> in second command.

This will give list of history of file changing within the branch.

Providing an actual answer.

What is the difference between .Net Core and Mono?

.NET Core now officially is the future of .NET. It started for most part with a re-write of the ASP.NET MVC framework and console applications, which of course includes server applications. (Since it's Turing-complete and supports interop with C dlls, you could, if you absolutely wanted to, also write your own desktop applications with it, for example through 3rd-party libraries like Avalonia, which were a bit very basic at the time I first wrote this, which meant you were pretty much limited to web or server stuff.) Over time, many APIs have been added to .NET Core, so much so that after version 3.1, .NET Core will jump to version 5.0, be known as .NET 5.0 without the "Core", and that then will be the future of the .NET Framework. What used to be the full .NET Framework will linger around in maintenance mode as Full .NET Framework 4.8.x for a few decades, until it will die (maybe there are still going to be some upgrades, but I doubt it). In other words, .NET Core is the future of .NET, and Full .NET Framework will go the way of the Dodo/Silverlight/WindowsPhone.

The main point of .NET Core, apart from multi-platform support, is to improve performance, and to enable "native compilation"/self-contained-deployment (so you don't need .NET framework/VM installed on the target machine.
On the one hand, this means docker.io support on Linux, and on the other, self-contained deployment is useful in "cloud-computing", since then you can just use whatever version of the dotnet-CORE framework you like, and you don't have to worry about which version(s) of the .NET framework the sysadmin has actually installed.

While the .NET Core runtime supports multiple operating systems and processors, the SDK is a different story. And while the SDK supports multiple OS, ARM support for the SDK is/was still work in progress. .NET Core is supported by Microsoft. Dotnet-Core did not come with WinForms or WPF or anything like that.

• As of version 3.0, WinForms and WPF is also supported by .NET Core, but only on Windows, and only by C#. Not by VB.NET (VB.NET support planned for v5 in 2020). And there is no Forms Designer in .NET Core: it's being shipped with a Visual Studio update later, at an unspecified time.
• WebForms are still not supported by .NET Core, and there are no plans to support them, ever (Blazor is the new kid in town for that).
• .NET Core also comes with System.Runtime, which replaces mscorelib.
• Oftentimes, .NET Core is mixed up with NetStandard, which is a bit of a wrapper around System.Runtime/mscorelib (and some others), that allows you to write libraries that target .NET Core, Full .NET Framework and Xamarin (iOS/Android), all at the same time.
• the .NET Core SDK does not/did not work on ARM, at least not last time I checked.

"The Mono Project" is much older than .NET Core.
Mono is Spanish and means Monkey, and as a side-remark, the name has nothing to do with mononucleosis (hint: you could get a list of staff under http://primates.ximian.com/).
Mono was started in 2005 by Miguel de Icaza (the guy that started GNOME - and a few others) as an implementation of the .NET Framework for Linux (Ximian/SuSe/Novell). Mono includes Web-Forms, Winforms, MVC, Olive, and an IDE called MonoDevelop (also knows as Xamarin Studio or Visual Studio Mac). Basically the equivalent of (OpenJDK) JVM and (OpenJDK) JDK/JRE (as opposed to SUN/Oracle JDK). You can use it to get ASP.NET-WebForms + WinForms + ASP.NET-MVC applications to work on Linux.

Mono is supported by Xamarin (the new company name of what used to be Ximian, when they focused on the Mobile market, instead of the Linux market), and not by Microsoft.
(since Xamarin was bought by Microsoft, that's technically [but not culturally] Microsoft.)
You will usually get your C# stuff to compile on mono, but not the VB.NET stuff.
Mono misses some advanced features, like WSE/WCF and WebParts.
Many of the Mono implementations are incomplete (e.g. throw NotImplementedException in ECDSA encryption), buggy (e.g. ODBC/ADO.NET with Firebird), behave differently than on .NET (for example XML-serialization) or otherwise unstable (ASP.NET MVC) and unacceptably slow (Regex). On the upside, the Mono toolchain also works on ARM.

As far as .NET Core is concerned, when they say cross-platform, don't expect that cross-platform means that you could actually just apt-get install .NET Core on ARM-Linux, like you can with ElasticSearch. You'll have to compile the entire framework from source.
That is, if you have that space (e.g. on a Chromebook, which has a 16 to 32 GB total HD).
It also used to have issues of incompatibility with OpenSSL 1.1 and libcurl.
Those have been rectified in the latest version of .NET Core Version 2.2.
So much for cross-platform.

I found a statement on the official site that said, "Code written for it is also portable across application stacks, such as Mono".

As long as that code doesn't rely on WinAPI-calls, Windows-dll-pinvokes, COM-Components, a case-insensitive file system, the default-system-encoding (codepage) and doesn't have directory separator issues, that's correct. However, .NET Core code runs on .NET Core, and not on Mono. So mixing the two will be difficult. And since Mono is quite unstable and slow (for web applications), I wouldn't recommend it anyway. Try image-processing on .NET core, e.g. WebP or moving GIF or multipage-tiff or writing text on an image, you'll be nastily surprised.

Note:
As of .NET Core 2.0, there is System.Drawing.Common (NuGet), which contains most of the functionality of System.Drawing. It should be more or less feature-complete in .NET-Core 2.1. However, System.Drawing.Common uses GDI+, and therefore won't work on Azure (System.Drawing libraries are available in Azure Cloud Service [basically just a VM], but not in Azure Web App [basically shared hosting?])
So far, System.Drawing.Common works fine on Linux/Mac, but has issues on iOS/Android - if it works at all, there.
Prior to .NET Core 2.0, that is to say sometime mid-February 2017, you could use SkiaSharp for imaging (example) (you still can).
Post .net-core 2.0, you'll notice that SixLabors ImageSharp is the way to go, since System.Drawing is not necessarely secure, and has a lot of potential or real memory leaks, which is why you shouldn't use GDI in web-applications; Note that SkiaSharp is a lot faster than ImageSharp, because it uses native-libraries (which can also be a drawback). Also, note that while GDI+ works on Linux & Mac, that doesn't mean it works on iOS/Android.

Code not written for .NET (non-Core) is not portable to .NET Core.
Meaning, if you want a non-GPL C# library like PDFSharp to create PDF-documents (very commonplace), you're out of luck (at the moment) (not anymore). Never mind ReportViewer control, which uses Windows-pInvokes (to encrypt, create mcdf documents via COM, and to get font, character, kerning, font embedding information, measure strings and do line-breaking, and for actually drawing tiffs of acceptable quality), and doesn't even run on Mono on Linux
(I'm working on that).

Also, code written in .NET Core is not portable to Mono, because Mono lacks the .NET Core runtime libraries (so far).

My goal is to use C#, LINQ, EF7, visual studio to create a website that can be ran/hosted in linux.

EF in any version that I tried so far was so goddamn slow (even on such simple things like one table with one left-join), I wouldn't recommend it ever - not on Windows either.
I would particularly not recommend EF if you have a database with unique-constrains, or varbinary/filestream/hierarchyid columns. (Not for schema-update either.)
And also not in a situation where DB-performance is critical (say 10+ to 100+ concurrent users).
Also, running a website/web-application on Linux will sooner or later mean you'll have to debug it.
There is no debugging support for .NET Core on Linux. (Not anymore, but requires JetBrains Rider.)
MonoDevelop does not (yet) support debugging .NET Core projects.
If you have problems, you're on your own. You'll have to use extensive logging.
Be careful, be advised extensive logging will fill your disk in no time, particularly if your program enters an infinite loop or recursion.
This is especially dangerous if your web-app runs as root, because log-in requires logfile-space - if there's no free space left, you won't be able to login anymore.
(Normally, about 5% of diskspace is reserved for user root [aka administrator on Windows], so at least the administrator can still log in if the disk is almost full. But if your applications run as root, that restriction does not apply for their disk usage, and so their logfiles can use 100% of the remaining free space, so not even the administrator can log in any more.)
It's therefore better not to encrypt that disk, that is, if you value your data/system.

Someone told me that he wanted it to be "in Mono", but I don't know what that means.

It either means he doesn't want to use .NET Core, or he just wants to use C# on Linux/Mac. My guess is he just wants to use C# for a Web-App on Linux. .NET Core is the way to go for that, if you absolutely want to do it in C#. Don't go with "Mono proper"; on the surface, it would seem to work at first - but believe me you will regret it because Mono's ASP.NET MVC isn't stable when your server runs long-term (longer than 1 day) - you have now been warned. See also the "did not complete" references when measuring Mono performance on the techempower benchmarks.

I know I want to use the .Net Core 1.0 framework with the technologies I listed above. He also said he wanted to use "fast cgi". I don't know what that means either.

It means he wants to use a high-performance full-featured WebServer like nginx (Engine-X), possibly Apache.
Then he can run mono/dotnetCore with virtual name based hosting (multiple domain names on the same IP) and/or load-balancing. He can also run other websites with other technologies, without requiring a different port-number on the web-server. It means your website runs on a fastcgi-server, and nginx forwards all web-requests for a certain domain via the fastcgi-protocol to that server. It also means your website runs in a fastcgi-pipeline, and you have to be careful what you do, e.g. you can't use HTTP 1.1 when transmitting files.
Otherwise, files will be garbled at the destination.
See also here and here.

To conclude:
.NET Core at present (2016-09-28) is not really portable, nor is is really cross-platform (in particular the debug-tools).
Nor is native-compilation easy, especially for ARM.
And to me, it also does not look like its development is "really finished", yet.
For example, System.Data.DataTable/DataAdaper.Update is missing... (not anymore with .NET Core 2.0)
Together with the System.Data.Common.IDB* interfaces. (not anymore with .NET Core 1.1)
if there ever was one class that is often used, DataTable/DataAdapter would be it...
Also, the Linux-installer (.deb) fails, at least on my machine, and I'm sure I'm not the only one that has that problem.
Debug, maybe with Visual Studio Code, if you can build it on ARM (I managed to do that - do NOT follow Scott Hanselman's blog-post if you do that - there's a howto in the wiki of VS-Code on github), because they don't offer the executable.
Yeoman also fails. (I guess it has something to do with the nodejs version you installed - VS Code requires one version, Yeoman another... but it should run on the same computer. pretty lame
Never mind that it should run on the node version shipped by default on the OS.
Never mind that there should be no dependency on NodeJS in the first place.
The kestell server is also work in progress.
And judging by my experience with the mono-project, I highly doubt they ever tested .NET Core on FastCGI, or that they have any idea what FastCGI-support means for their framework, let alone that they tested it to make sure "everything works". In fact, I just tried making a fastcgi-application with .NET Core and just realized there is no FastCGI library for .NET Core "RTM"...

So when you're going to run .NET Core "RTM" behind nginx, you can only do it by proxying requests to kestrell (that semi-finished nodeJS-derived web-server) - there's no fastcgi support at present in .NET Core "RTM", AFAIK. Since there is no .net core fastcgi library, and no samples, it's also highly unlikely that anybody did any testing on the framework to make sure fastcgi works as expected.

I also question the performance.
In the (preliminary) techempower-benchmark (round 13), aspnetcore-linux ranks on 25% relative to the best performance, while comparable frameworks like Go (golang) rank at 96.9% of peak performance (and that is when returning plaintext without file-system access only). .NET Core does a little better on JSON-serialization, but it does not look compelling either (go reaches 98.5% of peak, .NET core 65%). That said, it can't possibly be worse than "mono proper".

Also, since it's still relatively new, not all of the major libraries have been ported (yet), and I doubt that some of them will ever be ported.
Imaging support is also questionable at best.
For anything encryption, use BouncyCastle instead.

Can you help me make sense of all these terms and if my expectations are realistic?

I hope i helped you making more sense with all these terms.
As far as your expecations go:
Developing a Linux application without knowing anything about Linux is a really stupid idea in the first place, and it's also bound to fail in some horrible way one way or the other. That said, because Linux comes at no licensing costs, it's a good idea in principle, BUT ONLY IF YOU KNOW WHAT YOU DO.
Developing an application for a platform where you can't debug your application on is another really bad idea.
Developing for fastcgi without knowing what consequences there are is yet another really bad idea.

Doing all these things on a "experimental" platform without any knowledge of that platform's specifics and without debugging support is suicide, if your project is more than just a personal homepage. On the other hand, I guess doing it with your personal homepage for learning purposes would probably be a very good experience - then you get to know what the framework and what the non-framework problems are.
You can for example (programmatically) loop-mount a case-insensitive fat32, hfs or JFS for your application, to get around the case-sensitivity issues (loop-mount not recommended in production).

To summarize
At present (2016-09-28), I would stay away from .NET Core (for production usage). Maybe in one to two years, you can take another look, but probably not before.
If you have a new web-project that you develop, start it in .NET Core, not mono.

If you want a framework that works on Linux (x86/AMD64/ARMhf) and Windows and Mac, that has no dependencies, i.e. only static linking and no dependency on .NET, Java or Windows, use Golang instead. It's more mature, and its performance is proven (Baidu uses it with 1 million concurrent users), and golang has a significantly lower memory footprint. Also golang is in the repositories, the .deb installs without problems, the sourcecode compiles - without requiring changes - and golang (in the meantime) has debugging support with delve and JetBrains Gogland on Linux (and Windows and Mac). Golang's build process (and runtime) also doesn't depend on NodeJS, which is yet another plus.

As far as mono goes, stay away from it.
It is nothing short of amazing how far mono has come, but unfortunately that's no substitute for its performance/scalability and stability issues for production applications.
Also, mono-development is quite dead, they largely only develop the parts relevant to Android and iOS anymore, because that's where Xamarin makes their money.
Don't expect Web-Development to be a first-class Xamarin/mono citizen.
.NET Core might be worth it, if you start a new project, but for existing large web-forms projects, porting over is largely out of the question, the changes required are huge. If you have a MVC-project, the amount of changes might be manageable, if your original application design was sane, which is mostly not the case for most existing so-called "historically grown" applications.

December 2016 Update:
Native compilation has been removed from .NET Core preview, as it is not yet ready...

Seems like they have improved pretty heavily on the raw text-file benchmark, but on the other hand, it's gotten pretty buggy. Also, it further deteriorated in the JSON benchmarks. Curious also that entity framework shall be faster for updates than Dapper - although both at record slowness. This is very unlikely to be true. Looks like there still are more than just a few bugs to hunt.

Also, there seems to be relief coming on the Linux IDE front.
JetBrains released "Project Rider", an early access preview of a C#/.NET Core IDE for Linux (and Mac and Windows), that can handle Visual Studio Project files. Finally a C# IDE that is usable & that isn't slow as hell.

Conclusion: .NET Core still is pre-release quality software as we march into 2017. Port your libraries, but stay away from it for production usage, until framework quality stabilizes.
And keep an eye on Project Rider.

2017 Update
Have migrated my (brother's) homepage to .NET Core for now.
So far, the runtime on Linux seems to be stable enough (at least for small projects) - it survived a load test with ease - mono never did.
Also, it looks like I mixed up .NET-Core-native and .NET-Core-self-contained-deployment. Self-contained deployment works, but it is a bit underdocumented, although it's super easy (the build/publish tools are a bit unstable, yet - if you encounter "Positive number required. - Build FAILED." - run the same command again, and it works).

You can run

dotnet restore -r win81-x64
dotnet build -r win81-x64
dotnet publish -f netcoreapp1.1 -c Release -r win81-x64

Note: As per .NET Core 3, you can publish everything minified as a single file:

dotnet publish -r win-x64 -c Release /p:PublishSingleFile=true
dotnet publish -r linux-x64 -c Release /p:PublishSingleFile=true

However, unlike go, it's not a statically linked executable, but a self-extracting zip file, so when deploying, you might run into problems, especially if the temp directory is locked down by group policy, or some other issues. Works fine for a hello-world program, though. And if you don't minify, the executable size will clock in at something around 100 MB.

And you get a self-contained .exe-file (in the publish directory), which you can move to a Windows 8.1 machine without .NET framework installed and let it run. Nice. It's here that dotNET-Core just starts to get interesting. (mind the gaps, SkiaSharp doesn't work on Windows 8.1 / Windows Server 2012 R2, [yet] - the ecosystem has to catch up first - but interestingly, the Skia-dll-load-fail doesn't crash the entire server/application - so everything else works)

(Note: SkiaSharp on Windows 8.1 is missing the appropriate VC runtime files - msvcp140.dll and vcruntime140.dll. Copy them into the publish-directory, and Skia will work on Windows 8.1.)

August 2017 Update
.NET Core 2.0 released.
Be careful - comes with (huge breaking) changes in authentication...
On the upside, it brought the DataTable/DataAdaper/DataSet classes back, and many more.
Realized .NET Core is still missing support for Apache SparkSQL, because Mobius isn't yet ported. That's bad, because that means no SparkSQL support for my IoT Cassandra Cluster, so no joins...
Experimental ARM support (runtime only, not SDK - too bad for devwork on my Chromebook - looking forward to 2.1 or 3.0).
PdfSharp is now experimentally ported to .NET Core.
JetBrains Rider left EAP. You can now use it to develop & debug .NET Core on Linux - though so far only .NET Core 1.1 until the update for .NET Core 2.0 support goes live.

May 2018 Update
.NET Core 2.1 release imminent. Maybe this will fix NTLM-authentication on Linux (NTLM authentication doesn't work on Linux {and possibly Mac} in .NET-Core 2.0 with multiple authenticate headers, such as negotiate, commonly sent with ms-exchange, and they're apparently only fixing it in v2.1, no bugfix release for 2.0).
But I'm not installing preview releases on my machine. So waiting.
v2.1 is also said to greatly reduce compile times. That would be good.

Also, note that on Linux, .NET Core is 64-Bit only !
There is no, and there will be no, x86-32 version of .NET Core on Linux.
And the ARM port is ARM-32 only. No ARM-64, yet.
And on ARM, you (at present) only have the runtime, not the dotnet-SDK.

And one more thing:
Because .NET-Core uses OpenSSL 1.0, .NET Core on Linux doesn't run on Arch Linux, and by derivation not on Manjaro (the most popular Linux distro by far at this point in time), because Arch Linux uses OpenSSL 1.1. So if you're using Arch Linux, you're out of luck (with Gentoo, too).

Edit:

Latest version of .NET Core 2.2+ supports OpenSSL 1.1. So you can use it on Arch or (k)Ubuntu 19.04+. You might have to use the .NET-Core install script though, because there are no packages, yet.

On the upside, performance has definitely improved:

.NET Core 3:
.NET-Core v 3.0 is said to bring WinForms and WPF to .NET-Core.
However, while WinForms and WPF will be .NET Core, WinForms and WPF in .NET-Core will run on Windows only, because WinForms/WPF will use the Windows-API.

Note:
.NET Core 3.0 is now out (RTM), and there is WinForms and WPF support, but only for C# (on Windows). There is no WinForms-Core-Designer. The designer will, eventually, come with a Visual Studio update, somewhen. WinForms support for VB.NET is not supported, but is planned for .NET 5.0 somewhen in 2020.

PS:

echo "DOTNET_CLI_TELEMETRY_OPTOUT=1" >> /etc/environment
export DOTNET_CLI_TELEMETRY_OPTOUT=1 

If you've used it on windows, you probably never saw this:

The .NET Core tools collect usage data in order to improve your experience.
The data is anonymous and does not include command-line arguments.
The data is collected by Microsoft and shared with the community.
You can opt out of telemetry by setting a DOTNET_CLI_TELEMETRY_OPTOUT environment variable to 1 using your favorite shell.
You can read more about .NET Core tools telemetry @ https://aka.ms/dotnet-cli-telemetry.

I thought I'd mention that I think monodevelop (aka Xamarin Studio, the Mono IDE, or Visual Studio Mac as it is now called on Mac) has evolved quite nicely, and is - in the meantime - largely usable.
However, JetBrains Rider (2018 EAP at this point in time) is definitely a lot nicer and more reliable (and the included decompiler is a life-safer), that is to say, if you develop .NET-Core on Linux or Mac. MonoDevelop does not support Debug-StepThrough on Linux in .NET Core, though, since MS does not license their debugging API dll (except for VisualStudio Mac ... ). However, you can use the Samsung debugger for .NET Core through the .NET Core debugger extension for Samsung Debugger for MonoDevelop

Disclaimer:
I don't use Mac, so I can't say if what I wrote here applies to FreeBSD-Unix based Mac as well. I am refering to the Linux (Debian/Ubuntu/Mint) version of JetBrains Rider, mono, MonoDevelop/VisualStudioMac/XamarinStudio and .NET-Core. Also, Apple is contemplating a move from Intel-processors to self-manufactured ARM(ARM-64?)-based processors, so much of what applies to Mac right now might not apply to Mac in the future (2020+).

Also, when I write "mono is quite unstable and slow", the unstable relates to WinFroms & WebForms applications, specifically executing web-applications via fastcgi or with XSP (on the 4.x version of mono), as well as XML-serialization-handling peculiarities, and the quite-slow relates to WinForms, and regular expressions in particular (ASP.NET-MVC uses regular expressions for routing as well).

When I write about my experience about mono 2.x, 3.x and 4.x, that also does not necessarely mean these issues haven't been resolved by now, or by the time you are reading this, nor that if they are fixed now, that there can't be a regression later that reintroduces any of these bugs/features. Nor does that mean that if you embed the mono-runtime, you'll get the same results as when you use the (dev) system's mono runtime. It also doesn't mean that embedding the mono-runtime (anywhere) is necessarely free.

All that doesn't necessarely mean mono is ill-suited for iOS or Android, or that it has the same issues there. I don't use mono on Android or IOS, so I'm in no positon to say anything about stability, usability, costs and performance on these platforms. Obviously, if you use .NET on Android, you have some other costs considerations to do as well, such as weighting xamarin-costs vs. costs and time for porting existing code to Java. One hears mono on Android and IOS shall be quite good. Take it with a grain of salt. For one, don't expect the default-system-encoding to be the same on android/ios vs. Windows, and don't expect the android filesystem to be case-insensitive, and don't expect any windows fonts to be present.

One example more :)

double a = 1.00

if(floor(a) == a) {
   // a is an integer
} else {
   //a is not an integer.
}

In this example, ceil can be used and have the exact same effect.

$st = $data->prepare("SELECT * FROM exampleWHERE example LIKE :search LIMIT 10"); 

You can use the JDOM library in Java. Define your tags as Element objects, document your elements with Document Class, and build your xml file with SAXBuilder. Try this example:

//Root Element
Element root=new Element("CONFIGURATION");
Document doc=new Document();
//Element 1
Element child1=new Element("BROWSER");
//Element 1 Content
child1.addContent("chrome");
//Element 2
Element child2=new Element("BASE");
//Element 2 Content
child2.addContent("http:fut");
//Element 3
Element child3=new Element("EMPLOYEE");
//Element 3 --> In this case this element has another element with Content
child3.addContent(new Element("EMP_NAME").addContent("Anhorn, Irene"));

//Add it in the root Element
root.addContent(child1);
root.addContent(child2);
root.addContent(child3);
//Define root element like root
doc.setRootElement(root);
//Create the XML
XMLOutputter outter=new XMLOutputter();
outter.setFormat(Format.getPrettyFormat());
outter.output(doc, new FileWriter(new File("myxml.xml")));

Beware of the use of push method, if you don't use indexes, it won't work!

var main2dArray: Things[][] = []

main2dArray.push(someTmp1dArray)
main2dArray.push(someOtherTmp1dArray)

gives only a 1 line array!

use

main2dArray[0] = someTmp1dArray
main2dArray[1] = someOtherTmp1dArray

to get your 2d array working!!!

Other beware! foreach doesn't seem to work with 2d arrays!

On a Mac, credentials are stored in Keychain Access. Look for Github and remove that credential. More info: https://help.github.com/articles/updating-credentials-from-the-osx-keychain/

I get consistent behaviour for both instances:

>>> ls[0:10]
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> ls[10:-1]
[10, 11, 12, 13, 14, 15, 16, 17, 18]

Note, though, that tenth element of the list is at index 9, since the list is 0-indexed. That might be where your hang-up is.

In other words, [0:10] doesn't go from index 0-10, it effectively goes from 0 to the tenth element (which gets you indexes 0-9, since the 10 is not inclusive at the end of the slice).

If you are presenting a ViewController modally, and want to go back to the root ViewController, take care to dismiss this modally presented ViewController before you go back to the root ViewController otherwise this ViewController will not be removed from Memory and cause Memory leaks.

Works in a fragment with Android 10 (API 29)

val activityView = activity?.window?.decorView?.rootView
activityView?.let {
    val imm = activity?.getSystemService(Context.INPUT_METHOD_SERVICE) as? InputMethodManager
    imm?.hideSoftInputFromWindow(it.windowToken, 0)
}

you can also use

Here are a few ways to create a list with N of continuous natural numbers starting from 1.

1 range:

def numbers(n): 
    return range(1, n+1);

2 List Comprehensions:

def numbers(n):
    return [i for i in range(1, n+1)]

You may want to look into the method xrange and the concepts of generators, those are fun in python. Good luck with your Learning!

An IEnumerator is a thing that can enumerate: it has the Current property and the MoveNext and Reset methods (which in .NET code you probably won't call explicitly, though you could).

An IEnumerable is a thing that can be enumerated...which simply means that it has a GetEnumerator method that returns an IEnumerator.

Which do you use? The only reason to use IEnumerator is if you have something that has a nonstandard way of enumerating (that is, of returning its various elements one-by-one), and you need to define how that works. You'd create a new class implementing IEnumerator. But you'd still need to return that IEnumerator in an IEnumerable class.

For a look at what an enumerator (implementing IEnumerator<T>) looks like, see any Enumerator<T> class, such as the ones contained in List<T>, Queue<T>, or Stack<T>. For a look at a class implementing IEnumerable, see any standard collection class.

In the codebase I'm working with (1 million + lines of code) we had a problem with long startup times, around 60 seconds. We were getting 12000+ FactoryBeanNotInitializedException.

What I did was set a conditional breakpoint in AbstractBeanFactory#doGetBean

catch (BeansException ex) {
   // Explicitly remove instance from singleton cache: It might have been put there
   // eagerly by the creation process, to allow for circular reference resolution.
   // Also remove any beans that received a temporary reference to the bean.
   destroySingleton(beanName);
   throw ex;
}

where it does destroySingleton(beanName) I printed the exception with conditional breakpoint code:

   System.out.println(ex);
   return false;

Apparently this happens when FactoryBeans are involved in a cyclic dependency graph. We solved it by implementing ApplicationContextAware and InitializingBean and manually injecting the beans.

import org.springframework.beans.BeansException;
import org.springframework.beans.factory.InitializingBean;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;

public class A implements ApplicationContextAware, InitializingBean{

    private B cyclicDepenency;
    private ApplicationContext ctx;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext)
            throws BeansException {
        ctx = applicationContext;
    }
    @Override
    public void afterPropertiesSet() throws Exception {
        cyclicDepenency = ctx.getBean(B.class);
    }

    public void useCyclicDependency()
    {
        cyclicDepenency.doSomething();
    }
}

This cut down the startup time to around 15 secs.

So don't always assume that spring can be good at solving these references for you.

For this reason I'd recommend disabling cyclic dependency resolution with AbstractRefreshableApplicationContext#setAllowCircularReferences(false) to prevent many future problems.

In case anyone was a tired and silly as I was the other night whereupon I came across many threads espousing the different methods to get a javascript redirect, all of which were failing...

You can't use window.location.replace or document.location.href or any of your favourite vanilla javascript methods to redirect a page to itself.

So if you're dynamically adding in the redirect path from the back end, or pulling it from a data tag, make sure you do check at some stage for redirects to the current page. It could be as simple as:

if(window.location.href == linkout)
{
    location.reload();
}
else
{
    window.location.href = linkout;
}

Data-Binding

You go around making your webpage, and keep on putting {{data bindings}} whenever you feel you would have dynamic data. Angular will then provide you a $scope handler, which you can populate (statically or through calls to the web server).

This is a good understanding of data-binding. I think you've got that down.

DOM Manipulation

For simple DOM manipulation, which doesnot involve data manipulation (eg: color changes on mousehover, hiding/showing elements on click), jQuery or old-school js is sufficient and cleaner. This assumes that the model in angular's mvc is anything that reflects data on the page, and hence, css properties like color, display/hide, etc changes dont affect the model.

I can see your point here about "simple" DOM manipulation being cleaner, but only rarely and it would have to be really "simple". I think DOM manipulation is one the areas, just like data-binding, where Angular really shines. Understanding this will also help you see how Angular considers its views.

I'll start by comparing the Angular way with a vanilla js approach to DOM manipulation. Traditionally, we think of HTML as not "doing" anything and write it as such. So, inline js, like "onclick", etc are bad practice because they put the "doing" in the context of HTML, which doesn't "do". Angular flips that concept on its head. As you're writing your view, you think of HTML as being able to "do" lots of things. This capability is abstracted away in angular directives, but if they already exist or you have written them, you don't have to consider "how" it is done, you just use the power made available to you in this "augmented" HTML that angular allows you to use. This also means that ALL of your view logic is truly contained in the view, not in your javascript files. Again, the reasoning is that the directives written in your javascript files could be considered to be increasing the capability of HTML, so you let the DOM worry about manipulating itself (so to speak). I'll demonstrate with a simple example.

This is the markup we want to use. I gave it an intuitive name.

<div rotate-on-click="45"></div>

First, I'd just like to comment that if we've given our HTML this functionality via a custom Angular Directive, we're already done. That's a breath of fresh air. More on that in a moment.

Implementation with jQuery

live demo here (click).

function rotate(deg, elem) {
  $(elem).css({
    webkitTransform: 'rotate('+deg+'deg)', 
    mozTransform: 'rotate('+deg+'deg)', 
    msTransform: 'rotate('+deg+'deg)', 
    oTransform: 'rotate('+deg+'deg)', 
    transform: 'rotate('+deg+'deg)'    
  });
}

function addRotateOnClick($elems) {
  $elems.each(function(i, elem) {
    var deg = 0;
    $(elem).click(function() {
      deg+= parseInt($(this).attr('rotate-on-click'), 10);
      rotate(deg, this);
    });
  });
}

addRotateOnClick($('[rotate-on-click]'));

Implementation with Angular

live demo here (click).

app.directive('rotateOnClick', function() {
  return {
    restrict: 'A',
    link: function(scope, element, attrs) {
      var deg = 0;
      element.bind('click', function() {
        deg+= parseInt(attrs.rotateOnClick, 10);
        element.css({
          webkitTransform: 'rotate('+deg+'deg)', 
          mozTransform: 'rotate('+deg+'deg)', 
          msTransform: 'rotate('+deg+'deg)', 
          oTransform: 'rotate('+deg+'deg)', 
          transform: 'rotate('+deg+'deg)'    
        });
      });
    }
  };
});

Pretty light, VERY clean and that's just a simple manipulation! In my opinion, the angular approach wins in all regards, especially how the functionality is abstracted away and the dom manipulation is declared in the DOM. The functionality is hooked onto the element via an html attribute, so there is no need to query the DOM via a selector, and we've got two nice closures - one closure for the directive factory where variables are shared across all usages of the directive, and one closure for each usage of the directive in the link function (or compile function).

Two-way data binding and directives for DOM manipulation are only the start of what makes Angular awesome. Angular promotes all code being modular, reusable, and easily testable and also includes a single-page app routing system. It is important to note that jQuery is a library of commonly needed convenience/cross-browser methods, but Angular is a full featured framework for creating single page apps. The angular script actually includes its own "lite" version of jQuery so that some of the most essential methods are available. Therefore, you could argue that using Angular IS using jQuery (lightly), but Angular provides much more "magic" to help you in the process of creating apps.

This is a great post for more related information: How do I “think in AngularJS” if I have a jQuery background?

General differences.

The above points are aimed at the OP's specific concerns. I'll also give an overview of the other important differences. I suggest doing additional reading about each topic as well.

Angular and jQuery can't reasonably be compared.

Angular is a framework, jQuery is a library. Frameworks have their place and libraries have their place. However, there is no question that a good framework has more power in writing an application than a library. That's exactly the point of a framework. You're welcome to write your code in plain JS, or you can add in a library of common functions, or you can add a framework to drastically reduce the code you need to accomplish most things. Therefore, a more appropriate question is:

Why use a framework?

Good frameworks can help architect your code so that it is modular (therefore reusable), DRY, readable, performant and secure. jQuery is not a framework, so it doesn't help in these regards. We've all seen the typical walls of jQuery spaghetti code. This isn't jQuery's fault - it's the fault of developers that don't know how to architect code. However, if the devs did know how to architect code, they would end up writing some kind of minimal "framework" to provide the foundation (achitecture, etc) I discussed a moment ago, or they would add something in. For example, you might add RequireJS to act as part of your framework for writing good code.

Here are some things that modern frameworks are providing:

• Templating
• Data-binding
• routing (single page app)
• clean, modular, reusable architecture
• security
• additional functions/features for convenience

Before I further discuss Angular, I'd like to point out that Angular isn't the only one of its kind. Durandal, for example, is a framework built on top of jQuery, Knockout, and RequireJS. Again, jQuery cannot, by itself, provide what Knockout, RequireJS, and the whole framework built on top them can. It's just not comparable.

If you need to destroy a planet and you have a Death Star, use the Death star.

Angular (revisited).

Building on my previous points about what frameworks provide, I'd like to commend the way that Angular provides them and try to clarify why this is matter of factually superior to jQuery alone.

DOM reference.

In my above example, it is just absolutely unavoidable that jQuery has to hook onto the DOM in order to provide functionality. That means that the view (html) is concerned about functionality (because it is labeled with some kind of identifier - like "image slider") and JavaScript is concerned about providing that functionality. Angular eliminates that concept via abstraction. Properly written code with Angular means that the view is able to declare its own behavior. If I want to display a clock:

<clock></clock>

Done.

Yes, we need to go to JavaScript to make that mean something, but we're doing this in the opposite way of the jQuery approach. Our Angular directive (which is in it's own little world) has "augumented" the html and the html hooks the functionality into itself.

MVW Architecure / Modules / Dependency Injection

Angular gives you a straightforward way to structure your code. View things belong in the view (html), augmented view functionality belongs in directives, other logic (like ajax calls) and functions belong in services, and the connection of services and logic to the view belongs in controllers. There are some other angular components as well that help deal with configuration and modification of services, etc. Any functionality you create is automatically available anywhere you need it via the Injector subsystem which takes care of Dependency Injection throughout the application. When writing an application (module), I break it up into other reusable modules, each with their own reusable components, and then include them in the bigger project. Once you solve a problem with Angular, you've automatically solved it in a way that is useful and structured for reuse in the future and easily included in the next project. A HUGE bonus to all of this is that your code will be much easier to test.

It isn't easy to make things "work" in Angular.

THANK GOODNESS. The aforementioned jQuery spaghetti code resulted from a dev that made something "work" and then moved on. You can write bad Angular code, but it's much more difficult to do so, because Angular will fight you about it. This means that you have to take advantage (at least somewhat) to the clean architecture it provides. In other words, it's harder to write bad code with Angular, but more convenient to write clean code.

Angular is far from perfect. The web development world is always growing and changing and there are new and better ways being put forth to solve problems. Facebook's React and Flux, for example, have some great advantages over Angular, but come with their own drawbacks. Nothing's perfect, but Angular has been and is still awesome for now. Just as jQuery once helped the web world move forward, so has Angular, and so will many to come.

If someone is having trouble with installing php-mbstring package in ubuntu do following sudo apt-get install libapache2-mod-php5

In a similar situation I got away with this:

someUtils.validateURL = function(url) {
    var parser = document.createElement('a');
    try {
        parser.href = url;
        return !!parser.hostname;
    } catch (e) {
        return false;
    }
};

i.e. why invent the wheel if browsers can do it for you? But, of course, this will only work in the browser.

there are various parts of parsed URL exactly how browser would interpret it:

parser.protocol; // => "http:"
parser.hostname; // => "example.com"
parser.port;     // => "8080"
parser.pathname; // => "/path/"
parser.search;   // => "?search=test"
parser.hash;     // => "#hash"
parser.host;     // => "example.com:3000"

Using these you can improve your validating function depending on the requirements. The only drawback is that it will accept relative URLs and use current page server's host and port. But you can use it for your advantage, by re-assembling the URL from parts and always passing it in full to your AJAX service.

What validateURL won't accept is invalid URL, e.g. http:\:8883 will return false, but :1234 is valid and is interpreted as http://pagehost.example.com/:1234 i.e. as a relative path.

UPDATE

This approach is no longer working with Chrome and other WebKit browsers. Even when URL is invalid, hostname is filled with some value, e.g. taken from base. It still helps to parse parts of URL, but will not allow to validate one.

Possible better no-own-parser approach is to use var parsedURL = new URL(url) and catch exceptions. See e.g. URL API. Supported by all major browsers and NodeJS, although still marked experimental.

I had a similar problem and solved it by combining the answers above

class FeedPost extends React.Component {
  constructor(props) {
    ...
    this.handleLayoutChange = this.handleLayoutChange.bind(this);
  }


handleLayoutChange() {
    this.feedPost.measure( (fx, fy, width, height, px, py) => {
      console.log('Component width is: ' + width)
      console.log('Component height is: ' + height)
      console.log('X offset to page: ' + px)
      console.log('Y offset to page: ' + py)
    })
  }

  render {
    return(
      <View onLayout={(event) => {this.handleLayoutChange(event) }} 
      ref={view => { this.feedPost = view; }} >
...

Now I can see the position of my feedPost element in the logs:

08-24 11:15:36.838  3727 27838 I ReactNativeJS: Component width is: 156
08-24 11:15:36.838  3727 27838 I ReactNativeJS: Component height is: 206
08-24 11:15:36.838  3727 27838 I ReactNativeJS: X offset to page: 188
08-24 11:15:36.838  3727 27838 I ReactNativeJS: Y offset to page: 870

I always considered the .hpp header to be a sort of portmanteau of .h and .cpp files...a header which contains implementation details as well.

Typically when I've seen (and use) .hpp as an extension, there is no corresponding .cpp file. As others have said, this isn't a hard and fast rule, just how I tend to use .hpp files.

This is often caused by an attempt to process a null object. An example, trying to empty a Bindable list that is null will trigger the exception:

public class MyViewModel {
    [BindableProperty]
    public virtual IList<Products> ProductsList{ get; set; }

    public MyViewModel ()
    {
        ProductsList.Clear(); // here is the problem
    }
}

This could easily be fixed by checking for null:

if (ProductsList!= null) ProductsList.Clear();

To keep the accordion nature intact when wanting to also use 'hide' and 'show' functions like .collapse( 'hide' ), you must initialize the collapsible panels with the parent property set in the object with toggle: false before making any calls to 'hide' or 'show'

// initialize collapsible panels
$('#accordion .collapse').collapse({
  toggle: false,
  parent: '#accordion'
});

// show panel one (will collapse others in accordion)
$( '#collapseOne' ).collapse( 'show' );

// show panel two (will collapse others in accordion)
$( '#collapseTwo' ).collapse( 'show' );

// hide panel two (will not collapse/expand others in accordion)
$( '#collapseTwo' ).collapse( 'hide' );

I use AWS Data Wrangler. For example:

import awswrangler as wr
import pandas as pd

# read a local dataframe
df = pd.read_parquet('my_local_file.gz')

# upload to S3 bucket
wr.s3.to_parquet(df=df, path='s3://mys3bucket/file_name.gz')

The same applies to csv files. Instead of read_parquet and to_parquet, use read_csv and to_csv with the proper file extension.

Try: if(parseInt(order)>0){....

You can try this, it works for me.

       var a = /^(?:\d{1,3}(?:,\d{3})*|\d+)(?:\.\d+)?$/;
       if(amount.match(a)){
           alert("matches");
       }else{
        alert("does not match"); 
       }
    }
</script>

If you are using openssl to convert the PKCS#12 certificate to public/private PEM keys, there is no need to rename the file. Assuming the file is called cert.pfx, the following three commands will create a public pem key and an encrypted private pem key:

openssl pkcs12 -in cert.pfx     -out cert.pem     -nodes -nokeys
openssl pkcs12 -in cert.pfx     -out cert_key.pem -nodes -nocerts
openssl rsa    -in cert_key.pem -out cert_key.pem -des3

The first two commands may prompt for an import password. This will be a password that was provided with the PKCS#12 file.

The third command will let you specify the encryption passphrase for the certificate. This is what you will enter when using the certificate.

You'd use a self-join on a table that "refers" to itself - e.g. a table of employees where managerid is a foreign-key to employeeid on that same table.

Example:

SELECT E.name, ME.name AS manager
FROM dbo.Employees E
LEFT JOIN dbo.Employees ME
ON ME.employeeid = E.managerid

You could use the TimeSpan constructor which takes a long for Ticks:

   String first = parts[0];//"hello"

    String second = parts[1];//"World"

You can use your IP address to get your 'country', 'city', 'isp' etc...
Just use one of the web-services that provide you with a simple api like http://ip-api.com which provide you a JSON service at http://ip-api.com/json. Simple send a Ajax (or Xhr) request and then parse the JSON to get whatever data you need.

var requestUrl = "http://ip-api.com/json";

$.ajax({
  url: requestUrl,
  type: 'GET',
  success: function(json)
  {
    console.log("My country is: " + json.country);
  },
  error: function(err)
  {
    console.log("Request failed, error= " + err);
  }
});

These values vary from person to person, especially for people who are colorblind.

I got it resolved by doing Repir on .NET framework Extended, in Add/Remove program ;

Using win2008R2, .NET framework 4.0

Do configure --help and see what other options are available.

It is very common to provide different options to override different locations. By standard, --prefix overrides all of them, so you need to override config location after specifying the prefix. This course of actions usually works for every automake-based project.

The worse case scenario is when you need to modify the configure script, or even worse, generated makefiles and config.h headers. But yeah, for Xfce you can try something like this:

./configure --prefix=/home/me/somefolder/mybuild/output/target --sysconfdir=/etc 

I believe that should do it.

Well, how about this !!

This code calculates both row and column count in a csv file. Try this out !!

    static int[] getRowsColsNo() {
    Scanner scanIn = null;
    int rows = 0;
    int cols = 0;
    String InputLine = "";
    try {
        scanIn = new Scanner(new BufferedReader(
                new FileReader("filename.csv")));
        scanIn.useDelimiter(",");
        while (scanIn.hasNextLine()) {
            InputLine = scanIn.nextLine();
            String[] InArray = InputLine.split(",");
            rows++;
            cols = InArray.length;
        }

    } catch (Exception e) {
        System.out.println(e);
    }
    return new int[] { rows, cols };
}

Yeah, I'm using tf 2.0-beta and want to enable/disable the default logging. The environment variable and methods in tf1.X don't seem to exist anymore.

I stepped around in PDB and found this to work:

# close the TF2 logger
tf2logger = tf.get_logger()
tf2logger.error('Close TF2 logger handlers')
tf2logger.root.removeHandler(tf2logger.root.handlers[0])

I then add my own logger API (in this case file-based)

logtf = logging.getLogger('DST')
logtf.setLevel(logging.DEBUG)

# file handler
logfile='/tmp/tf_s.log'
fh = logging.FileHandler(logfile)
fh.setFormatter( logging.Formatter('fh %(asctime)s %(name)s %(filename)s:%(lineno)d :%(message)s') )
logtf.addHandler(fh)
logtf.info('writing to %s', logfile)

Looks like the path you gave doesn't have any bootstrap files in them.

href="~/lib/bootstrap/dist/css/bootstrap.min.css"

Make sure the files exist over there , else point the files to the correct path, which should be in your case

href="~/node_modules/bootstrap/dist/css/bootstrap.min.css"
