First, download installer at: https://cygwin.com/setup-x86_64.exe (Windows 64bit), then:

# move installer to cygwin folder
mv C:/Users/<you>/Downloads/setup-x86_64.exe C:/cygwin64/

# add alias to bash_aliases
echo "alias cygwin='C:/cygwin64/setup-x86_64.exe -q -P'" >> ~/.bash_aliases
source ~/.bash_aliases

# add bash_aliases to bashrc if missing
echo "source ~/.bash_aliases" >> ~/.profile

e.g.

# install vim
cygwin vim

# see other options
cygwin --help

The correlation matrix is the standard way to express correlations between an arbitrary finite number of variables. The correlation matrix of N data vectors is a symmetric N × N matrix with unity diagonal. Only in the case N = 2 does this matrix have one free parameter.

You need to remove the static from your accessor methods - these methods need to be instance methods and access the instance variables

public class IDCard {
    public String name, fileName;
    public int id;

    public IDCard(final String name, final String fileName, final int id) {
        this.name = name;
        this.fileName = fileName
        this.id = id;
    }

    public String getName() {
        return name;
    }
}

You can the create an IDCard and use the accessor like this:

final IDCard card = new IDCard();
card.getName();

Each time you call new a new instance of the IDCard will be created and it will have it's own copies of the 3 variables.

If you use the static keyword then those variables are common across every instance of IDCard.

A couple of things to bear in mind:

1. don't add useless comments - they add code clutter and nothing else.
2. conform to naming conventions, use lower case of variable names - name not Name.

in order to make nginx recommended method with return 301 $scheme://example.com$request_uri; work with Ghost you will need to add in your main server block:

proxy_set_header    X-Real-IP           $remote_addr;
proxy_set_header    X-Forwarded-For     $proxy_add_x_forwarded_for;

I have a solution for Java/JPA/eclipselink/oracle when insert a long xml string (>4000) into a XMLTYPE column at Insert XML with more than 4000 characters into a Oracle XMLTYPE column. For clarity, include the same contents here in case the link not working

You need to convert xml string for more than 4000 charcaters into SQLXML type first.

Environment: jpa 2.1.0, eclipselink 2.5.2, oracle db 11gr2

SQL:

CREATE TABLE "XMLTEST"
( "ID" NUMBER(10,0) NOT NULL ENABLE, 
  "DESCRIPTION" VARCHAR2(50 CHAR) NOT NULL ENABLE, 
  "XML_TXT" "XMLTYPE" NOT NULL ENABLE
);

INSERT INTO XMLTEST (ID, DESCRIPTION, XML_TXT) VALUES (101, 'XML DATA', '<data>TEST</data>');
COMMIT;

DROP TABLE "XMLTEST";

Java Code

String sql = "INSERT INTO XMLTEST (ID, DESCRIPTION, XML_TXT) VALUES (?, ?, ?)";
String xmlDataStr = "<data>test...</data>"; // a long xml string with length > 4000 characters
Connection con = getEntityManager().unwrap(Connection.class);
SQLXML sqlXml = con.createSQLXML();
sqlXml.setString(xmlDataStr);

Java code - use PreparedStatement

PreparedStatement pstmt = con.prepareStatement(sql);
pstmt.setLong(1, 201);
pstmt.setLong(2, "Long XML Data");
pstmt.setSQLXML(3, sqlXml);
pstmt.execute();

Java code - use native query instead of PreparedStatement

Query query = getEntityManager().createNativeQuery(sql);
query.setParameter(1, 301);
query.setParameter(2, "Long XML Data");
query.setParameter(3, sqlXml);
query.executeUpdate();

If the column data type is datetime then you can do this following to eliminate time from datetime and compare between date range only.

where cast(getdate() as date) between cast(loginTime as date) and cast(logoutTime as date)

As most people have pointed out that subclassing UITableViewCell solves this issue. But the reason this not allowed because the prototype cell(UITableViewCell) is defined by Apple and you cannot add any of your own outlets to it.

ulimit -s unlimited lets the stack grow unlimited.

This may prevent your program from crashing if you write programs by recursion, especially if your programs are not tail recursive (compilers can "optimize" those), and the depth of recursion is large.

Just an answer for future me (maybe it helps someone else too!). If you try to run something like this in the query editor:

USE [Dbo]
GO

DECLARE @RC int

EXECUTE @RC = [dbo].[SomeStoredProcedure] 
   2018
  ,0
  ,'arg3'
GO

SELECT month, SUM(weight) AS weight, SUM(amount) AS amount 
FROM SomeTable AS e 
WHERE year = @year AND type = 'M'

And you get the error:

Must declare the scalar variable "@year"

That's because you are trying to run a bunch of code that includes BOTH the stored procedure execution AND the query below it (!). Just highlight the one you want to run or delete/comment out the one you are not interested in.

Use a DecimalFormat object with a format string of "0.#".

This works as you wish:

At least in PostgreSQL you can use the column number in the resultset in your GROUP BY clause:

SELECT 
 itemName as ItemName,
 substring(itemName, 1,1) as FirstLetter,
 Count(itemName)
FROM table1
GROUP BY 1, 2

Of course this starts to be a pain if you are doing this interactively and you edit the query to change the number or order of columns in the result. But still.

Just want to reiterate this will work in pandas >= 0.9.1:

In [2]: read_csv('sample.csv', dtype={'ID': object})
Out[2]: 
                           ID
0  00013007854817840016671868
1  00013007854817840016749251
2  00013007854817840016754630
3  00013007854817840016781876
4  00013007854817840017028824
5  00013007854817840017963235
6  00013007854817840018860166

I'm creating an issue about detecting integer overflows also.

EDIT: See resolution here: https://github.com/pydata/pandas/issues/2247

Update as it helps others:

To have all columns as str, one can do this (from the comment):

pd.read_csv('sample.csv', dtype = str)

To have most or selective columns as str, one can do this:

# lst of column names which needs to be string
lst_str_cols = ['prefix', 'serial']
# use dictionary comprehension to make dict of dtypes
dict_dtypes = {x : 'str'  for x in lst_str_cols}
# use dict on dtypes
pd.read_csv('sample.csv', dtype=dict_dtypes)

If your code doesn't require the file to be truncated first, you can use the FileMode.OpenOrCreate to open the filestream, which will create the file if it doesn't exist or open it if it does. You can use the stream to point at the front and start overwriting the existing file?

I'm assuming your using a streams here, there are other ways to write a file.

Edit I just finished a nice four part tutorial building an app to write, save, edit, & delete notes using jQuery mobile (only), it was very practical & useful, but it was also only for jQM. So, I looked to see what else they had on DZone.

I'm now going to start sorting through these search results. At a glance, it looks really promising. I remembered this post; so I thought I'd steer people to it. ?

Scenario 1 - you don't have a data-source for the items
You can just populate the ComboBox with static values as follows -
From XAML:

<ComboBox Height="23" Name="comboBox1" Width="120">
        <ComboBoxItem Content="X"/>
        <ComboBoxItem Content="Y"/>
        <ComboBoxItem Content="Z"/>
</ComboBox>  

Or, from CodeBehind:

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    comboBox1.Items.Add("X");
    comboBox1.Items.Add("Y");
    comboBox1.Items.Add("Z");
}  

Scenario 2.a - you have a data-source, and the items never get changed
You can use the data-source to populate the ComboBox. Any IEnumerable type can be used as the data-source. You need to assign it to the ItemsSource property of the ComboBox and that'll do just fine (it's up to you how you populate the IEnumerable).

Scenario 2.b - you have a data-source, and the items might get changed
You should use an ObservableCollection<T> as the data-source and assign it to the ItemsSource property of the ComboBox (it's up to you how you populate the ObservableCollection<T>). Using an ObservableCollection<T> ensures that whenever an item is added to or removed from the data-source, the change will reflect immediately on the UI.

df.tail(1).index 

seems the most readable

$sql = "select column_name from information_schema.columns where table_name = 'myTable'";

PHP function credits : http://www.sitepoint.com/forums/php-application-design-147/get-pdo-column-name-easy-way-559336.html

    function getColumnNames(){ 

    $sql = "select column_name from information_schema.columns where table_name = 'myTable'";
    #$sql = 'SHOW COLUMNS FROM ' . $this->table; 

    $stmt = $this->connection->prepare($sql); 

    try {     
        if($stmt->execute()){ 
            $raw_column_data = $stmt->fetchAll(PDO::FETCH_ASSOC); 

            foreach($raw_column_data as $outer_key => $array){ 
                foreach($array as $inner_key => $value){ 
                            if (!(int)$inner_key){ 
                                $this->column_names[] = $value; 
                            } 
                } 
            } 
            } 
            return $this->column_names; 
        } catch (Exception $e){ 
                return $e->getMessage(); //return exception 
        }         
    }  

The 'more than 100% width' on the table really made it work for me.

.table-wrap {_x000D_
    width: 100%;_x000D_
    overflow: auto;_x000D_
}_x000D_
_x000D_
table {_x000D_
    table-layout: fixed;_x000D_
    width: 200%;_x000D_
}

Here you can Find some other way to do the same.

Read file.

File file1 = new File("C:\Build\myfolder\myTestfile.txt");
def String yourData = file1.readLines();

Read Full file.

File file1 = new File("C:\Build\myfolder\myfile.txt");
def String yourData= file1.getText();

Read file Line Bye Line.

File file1 = new File("C:\Build\myfolder\myTestfile.txt");
for (def i=0;i<=30;i++) // specify how many line need to read eg.. 30
{
 log.info file1.readLines().get(i)

}

Create a new file.

new File("C:\Temp\FileName.txt").createNewFile();

RegQueryValueEx

This gives the value if it exists, and returns an error code ERROR_FILE_NOT_FOUND if the key doesn't exist.

(I can't tell if my link is working or not, but if you just google for "RegQueryValueEx" the first hit is the msdn documentation.)

You could make use of Prepared Stements like this.

set @query = concat( "select name from " );
set @query = concat( "table_name"," [where condition] " );

prepare stmt from @like_q;
execute stmt;

Another trick to get the link color working correctly inside the <button> markup

<button type="button" class="btn btn-outline-success and-all-other-classes"> 
  <a href="#" style="color:inherit"> Button text with correct colors </a>
</button>

Please keep in mind that in bs4 beta e.g. btn-primary-outline changed to btn-outline-primary

MATLAB's FOR loop is static in nature; you cannot modify the loop variable between iterations, unlike the for(initialization;condition;increment) loop structure in other languages. This means that the following code always prints 1, 2, 3, 4, 5 regardless of the value of B.

A = 1:5;

for i = A
    A = B;
    disp(i);
end

If you want to be able to respond to changes in the data structure during iterations, a WHILE loop may be more appropriate --- you'll be able to test the loop condition at every iteration, and set the value of the loop variable(s) as you wish:

n = 10;
f = n;
while n > 1
    n = n-1;
    f = f*n;
end
disp(['n! = ' num2str(f)])

Btw, the for-each loop in Java (and possibly other languages) produces unspecified behavior when the data structure is modified during iteration. If you need to modify the data structure, you should use an appropriate Iterator instance which allows the addition and removal of elements in the collection you are iterating. The good news is that MATLAB supports Java objects, so you can do something like this:

A = java.util.ArrayList();
A.add(1);
A.add(2);
A.add(3);
A.add(4);
A.add(5);

itr = A.listIterator();

while itr.hasNext()

    k = itr.next();
    disp(k);

    % modify data structure while iterating
    itr.remove();
    itr.add(k);

end

Ok guys, I found a solution, . It's not great but does the trick with no side effects.

The HTML:

<span id="chromeFix"></span> 

(put this below the body tags)

The CSS:

#chromeFix { display: block; position: absolute; width: 1px; height: 100%; top: 0px; left: 0px; }

What this does to solve the issue:

It forces Chrome to think the page's content is 100% when it's not - this stops the body 'appearing' the size of the content and resolves the missing background bug. This is basically doing what height: 100% does when applied to the body or html but you don't get the side effect of having your backgrounds cut off when scrolling (past 100% page height) like you do with a 100% height on those elements.

I recommend GitHub: Array sortBy - a best implementation of sortBy method which uses the Schwartzian transform

But for now we are going to try this approach Gist: sortBy-old.js.
Let's create a method to sort arrays being able to arrange objects by some property.

Creating the sorting function

var sortBy = (function () {
  var toString = Object.prototype.toString,
      // default parser function
      parse = function (x) { return x; },
      // gets the item to be sorted
      getItem = function (x) {
        var isObject = x != null && typeof x === "object";
        var isProp = isObject && this.prop in x;
        return this.parser(isProp ? x[this.prop] : x);
      };
      
  /**
   * Sorts an array of elements.
   *
   * @param {Array} array: the collection to sort
   * @param {Object} cfg: the configuration options
   * @property {String}   cfg.prop: property name (if it is an Array of objects)
   * @property {Boolean}  cfg.desc: determines whether the sort is descending
   * @property {Function} cfg.parser: function to parse the items to expected type
   * @return {Array}
   */
  return function sortby (array, cfg) {
    if (!(array instanceof Array && array.length)) return [];
    if (toString.call(cfg) !== "[object Object]") cfg = {};
    if (typeof cfg.parser !== "function") cfg.parser = parse;
    cfg.desc = !!cfg.desc ? -1 : 1;
    return array.sort(function (a, b) {
      a = getItem.call(cfg, a);
      b = getItem.call(cfg, b);
      return cfg.desc * (a < b ? -1 : +(a > b));
    });
  };
  
}());

Setting unsorted data

var data = [
  {date: "2011-11-14T17:25:45Z", quantity: 2, total: 200, tip: 0,   type: "cash"},
  {date: "2011-11-14T16:28:54Z", quantity: 1, total: 300, tip: 200, type: "visa"},
  {date: "2011-11-14T16:30:43Z", quantity: 2, total: 90,  tip: 0,   type: "tab"},
  {date: "2011-11-14T17:22:59Z", quantity: 2, total: 90,  tip: 0,   type: "tab"},
  {date: "2011-11-14T16:53:41Z", quantity: 2, total: 90,  tip: 0,   type: "tab"},
  {date: "2011-11-14T16:48:46Z", quantity: 2, total: 90,  tip: 0,   type: "tab"},
  {date: "2011-11-31T17:29:52Z", quantity: 1, total: 200, tip: 100, type: "visa"},
  {date: "2011-11-01T16:17:54Z", quantity: 2, total: 190, tip: 100, type: "tab"},
  {date: "2011-11-14T16:58:03Z", quantity: 2, total: 90,  tip: 0,   type: "tab"},
  {date: "2011-11-14T16:20:19Z", quantity: 2, total: 190, tip: 100, type: "tab"},
  {date: "2011-11-14T17:07:21Z", quantity: 2, total: 90,  tip: 0,   type: "tab"},
  {date: "2011-11-14T16:54:06Z", quantity: 1, total: 100, tip: 0,   type: "cash"}
];

Using it

Finally, we arrange the array, by "date" property as string

//sort the object by a property (ascending)
//sorting takes into account uppercase and lowercase
sortBy(data, { prop: "date" });

If you want to ignore letter case, set the "parser" callback:

//sort the object by a property (descending)
//sorting ignores uppercase and lowercase
sortBy(data, {
    prop: "date",
    desc: true,
    parser: function (item) {
        //ignore case sensitive
        return item.toUpperCase();
    }
});

If you want to treat the "date" field as Date type:

//sort the object by a property (ascending)
//sorting parses each item to Date type
sortBy(data, {
    prop: "date",
    parser: function (item) {
        return new Date(item);
    }
});

Here you can play with the above example:

I would rather make it like this

<video  id="v1" width="320" height="240" controls="controls">

</video>

and then use

$("#v1").html('<source src="test1.mp4" type="video/mp4"></source>' );

I had the same issue. Fistly, thats what i have :

1. win 10
2. xampp
3. git bash

and i have done this to fix my problem :

1. go to search box(PC)
2. tape this environnement variable
3. go to 'path' click 'edit'
4. add this "%systemDrive%\xampp\mysql\bin\" C:\xampp\mysql\bin\
5. click ok
6. go to Git Bash and right click it and open it and run as administrator
7. right this on your Git Bash winpty mysql -u root if your password is empty or winpty mysql -u root -p if you do have a password

I'm not sure if PyQt does have a script like this, but after you install PySide there is a script in pythons script directory "uic.py". You can use this script to convert a .ui file to a .py file:

python uic.py input.ui -o output.py -x

Load an image with characters as texture and draw the part of that texture depending on what character you want. You can create that texture using a paint program, hardcode it or use a window component to draw to an image and retrieve that image for an exact copy of system fonts.

No need to use Glut or any other extension, just basic OpenGL operability. It gets the job done, not to mention that its been done like this for decades by professional programmers in very succesfull games and other applications.

DataTable.NewRow will initialize each field to:

• the default value for each DataColumn (DataColumn.DefaultValue)

• except for auto-increment columns (DataColumn.AutoIncrement == true), which will be initialized to the next auto-increment value.

• and expression columns (DataColumn.Expression.Length > 0) are also a special case; the default value will depend on the default values of columns on which the expression is calculated.

So you should probably be checking something like:

bool isDirty = false;
for (int i=0; i<table.Columns.Count; i++)
{
    if (table.Columns[i].Expression.Length > 0) continue;
    if (table.Columns[i].AutoIncrement) continue;
    if (row[i] != table.Columns[i].DefaultValue) isDirty = true;
}

I'll leave the LINQ version as an exercise :)

UPDATE: As of compose file version 3.5:

This now works:

version: "3.5"
services:
  proxy:
    image: hello-world
    ports:
      - "80:80"
    networks:
      - proxynet

networks:
  proxynet:
    name: custom_network

docker-compose up -d will join a network called 'custom_network'. If it doesn't exist, it will be created!

root@ubuntu-s-1vcpu-1gb-tor1-01:~# docker-compose up -d
Creating network "custom_network" with the default driver
Creating root_proxy_1 ... done

Now, you can do this:

version: "2"
services:
  web:
    image: hello-world
    networks:
      - my-proxy-net
networks:
  my-proxy-net:
    external:
      name: custom_network

This will create a container that will be on the external network.

I can't find any reference in the docs yet but it works!

>>> a =numpy.array([[1,2],[3,4],[5,6]])
>>> for (x,y), value in numpy.ndenumerate(a):
...  print x,y
... 
0 0
0 1
1 0
1 1
2 0
2 1

Regarding the performance. It is a bit slower than a list comprehension.

X = np.zeros((100, 100, 100))

%timeit list([((i,j,k), X[i,j,k]) for i in range(X.shape[0]) for j in range(X.shape[1]) for k in range(X.shape[2])])
1 loop, best of 3: 376 ms per loop

%timeit list(np.ndenumerate(X))
1 loop, best of 3: 570 ms per loop

If you are worried about the performance you could optimise a bit further by looking at the implementation of ndenumerate, which does 2 things, converting to an array and looping. If you know you have an array, you can call the .coords attribute of the flat iterator.

a = X.flat
%timeit list([(a.coords, x) for x in a.flat])
1 loop, best of 3: 305 ms per loop

ONE-LINER

const b2s=t=>{let e=Math.log2(t)/10|0;return(t/1024**(e=e<=0?0:e)).toFixed(3)+"BKMGP"[e]};

console.log(b2s(0));
console.log(b2s(123));
console.log(b2s(123123));
console.log(b2s(123123123));
console.log(b2s(123123123123));
console.log(b2s(123123123123123));

I use always:

• quality in 85
• progressive (comprobed compression)
• a very tiny gausssian blur to optimize the size (0.05 or 0.5 of radius) depends on the quality and size of the picture, this notably optimizes the size of the jpeg.
• Strip any comment or EXIF metadata

in imagemagick should be

convert -strip -interlace Plane -gaussian-blur 0.05 -quality 85% source.jpg result.jpg

or in the newer version:

magick source.jpg -strip -interlace Plane -gaussian-blur 0.05 -quality 85% result.jpg

Source.

From @Fordi in the comments (Don't forget to upvote him if you like this): If you dislike blurring, use -sampling-factor 4:2:0 instead. What this does is reduce the chroma channel's resolution to half, without messing with the luminance resolution that your eyes latch onto. If you want better fidelity in the conversion, you can get a slight improvement without an increase in filesize by specifying -define jpeg:dct-method=float - that is, use the more accurate floating point discrete cosine transform, rather than the default fast integer version.

The best solution (for python >= 3.4) when executing from any directory is:

from pathlib import Path
two_up = Path(__file__).resolve().parents[1]

I had the same issue because my file was called email.py. I renamed the file and the issue disappeared.

Most of the time you don't need conversion:

>>>array([True,True,False,False]) + array([1,2,3,4])
array([2, 3, 3, 4])

The right way to do it is:

yourArray.astype(int)

or

yourArray.astype(float)

This an example from my code how to address a widget(button) in popupwindow

View v=LayoutInflater.from(getContext()).inflate(R.layout.popupwindow, null, false);
    final PopupWindow pw = new PopupWindow(v,500,500, true);
    final Button button = rootView.findViewById(R.id.button);
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            pw.showAtLocation(rootView.findViewById(R.id.constraintLayout), Gravity.CENTER, 0, 0);


        }
    });
    final Button popup_btn=v.findViewById(R.id.popupbutton);

    popup_btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            popup_btn.setBackgroundColor(Color.RED);
        }
    });

Hope this help you

Try below steps:

1. Go to your project's run configuration. In Classpath tab add JUnit library.
2. Retry the same steps.

It worked for me.

There are multiple ways to achieve this.

1. In case of just for existence. It could be file or a directory.

   new File("/path/to/file").exists();
   

2. Check for file

   File f = new File("/path/to/file"); 
     if(f.exists() && f.isFile()) {}
   

3. Check for Directory.

   File f = new File("/path/to/file"); 
     if(f.exists() && f.isDirectory()) {}
   

4. Java 7 way.

   Path path = Paths.get("/path/to/file");
   Files.exists(path)  // Existence 
   Files.isDirectory(path)  // is Directory
   Files.isRegularFile(path)  // Regular file 
   Files.isSymbolicLink(path)  // Symbolic Link
   

If you would like to insert multiple values lets say from multiple inputs that have different post values but the same table to insert into then simply use:

mysql_query("INSERT INTO `table` (a,b,c,d,e,f,g) VALUES 
('$a','$b','$c','$d','$e','$f','$g'),
('$a','$b','$c','$d','$e','$f','$g'),
('$a','$b','$c','$d','$e','$f','$g')")
or die (mysql_error()); // Inserts 3 times in 3 different rows

Though is answered in another stack overflow question Bind a function to Twitter Bootstrap Modal Close but for visual feel here is more detailed answer.

The reason for this error is that in Python 3, strings are Unicode, but when transmitting on the network, the data needs to be bytes instead. So... a couple of suggestions:

1. Suggest using c.sendall() instead of c.send() to prevent possible issues where you may not have sent the entire msg with one call (see docs).
2. For literals, add a 'b' for bytes string: c.sendall(b'Thank you for connecting')
3. For variables, you need to encode Unicode strings to byte strings (see below)

Best solution (should work w/both 2.x & 3.x):

output = 'Thank you for connecting'
c.sendall(output.encode('utf-8'))

Epilogue/background: this isn't an issue in Python 2 because strings are bytes strings already -- your OP code would work perfectly in that environment. Unicode strings were added to Python in releases 1.6 & 2.0 but took a back seat until 3.0 when they became the default string type. Also see this similar question as well as this one.

Personally, I use that:

    final Spinner spinner = (Spinner) (view.findViewById(R.id.userList));
    spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {                

            userSelectedIndex = position;
        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {
        }
    });  

New way to check the system version using the swift Forget [[UIDevice currentDevice] systemVersion] and NSFoundationVersionNumber.

We can use NSProcessInfo -isOperatingSystemAtLeastVersion

     import Foundation

     let yosemite = NSOperatingSystemVersion(majorVersion: 10, minorVersion: 10, patchVersion: 0)
     NSProcessInfo().isOperatingSystemAtLeastVersion(yosemite) // false

There is a surprisingly effective way that consists of using the easter eggs.

They differ from version to version.

I use a hidden textbox to edit all the listview items/subitems. The only problem is that the textbox needs to disappear as soon as any event takes place outside the textbox and the listview doesn't trigger the scroll event so if you scroll the listview the textbox will still be visible. To bypass this problem I created the Scroll event with this overrided listview.

Here is my code, I constantly reuse it so it might be help for someone:

ListViewItem.ListViewSubItem SelectedLSI;
private void listView2_MouseUp(object sender, MouseEventArgs e)
{
    ListViewHitTestInfo i = listView2.HitTest(e.X, e.Y);
    SelectedLSI = i.SubItem;
    if (SelectedLSI == null)
        return;

    int border = 0;
    switch (listView2.BorderStyle)
    {
        case BorderStyle.FixedSingle:
            border = 1;
            break;
        case BorderStyle.Fixed3D:
            border = 2;
            break;
    }

    int CellWidth = SelectedLSI.Bounds.Width;
    int CellHeight = SelectedLSI.Bounds.Height;
    int CellLeft = border + listView2.Left + i.SubItem.Bounds.Left;
    int CellTop =listView2.Top + i.SubItem.Bounds.Top;
    // First Column
    if (i.SubItem == i.Item.SubItems[0])
        CellWidth = listView2.Columns[0].Width;

    TxtEdit.Location = new Point(CellLeft, CellTop);
    TxtEdit.Size = new Size(CellWidth, CellHeight);
    TxtEdit.Visible = true;
    TxtEdit.BringToFront();
    TxtEdit.Text = i.SubItem.Text;
    TxtEdit.Select();
    TxtEdit.SelectAll();
}
private void listView2_MouseDown(object sender, MouseEventArgs e)
{
    HideTextEditor();
}
private void listView2_Scroll(object sender, EventArgs e)
{
    HideTextEditor();
}
private void TxtEdit_Leave(object sender, EventArgs e)
{
    HideTextEditor();
}
private void TxtEdit_KeyUp(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Enter || e.KeyCode == Keys.Return)
        HideTextEditor();
}
private void HideTextEditor()
{
    TxtEdit.Visible = false;
    if (SelectedLSI != null)
        SelectedLSI.Text = TxtEdit.Text;
    SelectedLSI = null;
    TxtEdit.Text = "";
}

I agree with both previous answers. Basically, you want to use what is known as a "lightbox" - http://en.wikipedia.org/wiki/Lightbox_(JavaScript)

It is essentially a div than is created within the DOM of your current window/tab. In addition to the div that contains your dialog, a transparent overlay blocks the user from engaging all underlying elements. This can effectively create a modal dialog (i.e. user MUST make some kind of decision before moving on).

Try:

git log --stat | grep file

Use this:

window.onresize = function(event) {
    ...
}

If you are only looking to point to a different location for you identity file, the you can modify your ~/.ssh/config file with the following entry:

IdentityFile ~/.foo/identity

man ssh_config to find other config options.

It must be at least 64 bits. Other than that it's implementation defined.

Strictly speaking, unsigned long long isn't standard in C++ until the C++0x standard. unsigned long long is a 'simple-type-specifier' for the type unsigned long long int (so they're synonyms).

The long long set of types is also in C99 and was a common extension to C++ compilers even before being standardized.

I was getting this warning when I wanted to show a popup (bootstrap modal) on success/failure callback of Ajax request. Additionally setState was not working and my popup modal was not being shown.

Below was my situation-

<Component /> (Containing my Ajax function)
    <ChildComponent />
        <GrandChildComponent /> (Containing my PopupModal, onSuccess callback)

I was calling ajax function of component from grandchild component passing a onSuccess Callback (defined in grandchild component) which was setting state to show popup modal.

I changed it to -

<Component /> (Containing my Ajax function, PopupModal)
    <ChildComponent />
        <GrandChildComponent /> 

Instead I called setState (onSuccess Callback) to show popup modal in component (ajax callback) itself and problem solved.

In 2nd case: component was being rendered twice (I had included bundle.js two times in html).

Fix of above function for play and pause

  public void playBeep ( String word )
{
    try
    {
        if ( ( m == null ) )
        {

            m = new MediaPlayer ();
        }
        else if( m != null&&lastPlayed.equalsIgnoreCase (word)){
            m.stop();
            m.release ();
            m=null;
            lastPlayed="";
            return;
        }else if(m != null){
            m.release ();
            m = new MediaPlayer ();
        }
        lastPlayed=word;

        AssetFileDescriptor descriptor = context.getAssets ().openFd ( "rings/" + word + ".mp3" );
        long                start      = descriptor.getStartOffset ();
        long                end        = descriptor.getLength ();

        // get title
        // songTitle=songsList.get(songIndex).get("songTitle");
        // set the data source
        try
        {
            m.setDataSource ( descriptor.getFileDescriptor (), start, end );
        }
        catch ( Exception e )
        {
            Log.e ( "MUSIC SERVICE", "Error setting data source", e );
        }

        m.prepare ();
        m.setVolume ( 1f, 1f );
        // m.setLooping(true);
        m.start ();
    }
    catch ( Exception e )
    {
        e.printStackTrace ();
    }
}

In this case you use -1.

Here's a quick method that worked for me. Simply fork the repo and install it from your own GitHub account with

pip install git+https://github.com/yourName/repoName

It's usually describes as for optional add-on software packagessource, or anything that isn't part of the base system. Only some distributions use it, others simply use /usr/local.

You need the following line:

<script src="../jquery/development-bundle/ui/i18n/jquery.ui.datepicker-sv.js"></script>

Adjust the path depending on where you put the jquery-files.

I followed @LachlanB approach and indeed the session was available when the session cookie was present on the request. The missing part is how the Session cookie is sent to the client the first time?

I created a HttpModule which not only enabling the HttpSessionState availability but also sends the cookie to the client when a new session is created.

public class WebApiSessionModule : IHttpModule
{
    private static readonly string SessionStateCookieName = "ASP.NET_SessionId";

    public void Init(HttpApplication context)
    {
        context.PostAuthorizeRequest += this.OnPostAuthorizeRequest;
        context.PostRequestHandlerExecute += this.PostRequestHandlerExecute;
    }

    public void Dispose()
    {
    }

    protected virtual void OnPostAuthorizeRequest(object sender, EventArgs e)
    {
        HttpContext context = HttpContext.Current;

        if (this.IsWebApiRequest(context))
        {
            context.SetSessionStateBehavior(SessionStateBehavior.Required);
        }
    }

    protected virtual void PostRequestHandlerExecute(object sender, EventArgs e)
    {
        HttpContext context = HttpContext.Current;

        if (this.IsWebApiRequest(context))
        {
            this.AddSessionCookieToResponseIfNeeded(context);
        }
    }

    protected virtual void AddSessionCookieToResponseIfNeeded(HttpContext context)
    {
        HttpSessionState session = context.Session;

        if (session == null)
        {
            // session not available
            return;
        }

        if (!session.IsNewSession)
        {
            // it's safe to assume that the cookie was
            // received as part of the request so there is
            // no need to set it
            return;
        }

        string cookieName = GetSessionCookieName();
        HttpCookie cookie = context.Response.Cookies[cookieName];
        if (cookie == null || cookie.Value != session.SessionID)
        {
            context.Response.Cookies.Remove(cookieName);
            context.Response.Cookies.Add(new HttpCookie(cookieName, session.SessionID));
        }
    }

    protected virtual string GetSessionCookieName()
    {
        var sessionStateSection = (SessionStateSection)ConfigurationManager.GetSection("system.web/sessionState");

        return sessionStateSection != null && !string.IsNullOrWhiteSpace(sessionStateSection.CookieName) ? sessionStateSection.CookieName : SessionStateCookieName;
    }

    protected virtual bool IsWebApiRequest(HttpContext context)
    {
        string requestPath = context.Request.AppRelativeCurrentExecutionFilePath;

        if (requestPath == null)
        {
            return false;
        }

        return requestPath.StartsWith(WebApiConfig.UrlPrefixRelative, StringComparison.InvariantCultureIgnoreCase);
    }
}

In a Spring project you can use

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

replace:

$name = $_POST['name']; 
$email_address = $_POST['email']; 
$message = $_POST['tel']; 

with:

$name = $_POST['name']; 
$email_address = $_POST['email']; 
$message = $_POST['tel'];
if (isset($_POST['newsletter'])) {
  $checkBoxValue = "yes";
} else {
  $checkBoxValue = "no";
}

then replace this line of code:

$email_body = "You have received a new message. ".
    " Here are the details:\n Name: $name \n Email: $email_address \n Tel \n $message\n Newsletter \n $newsletter"

with:

$email_body = "You have received a new message. ".
    " Here are the details:\n Name: $name \n Email: $email_address \n Tel \n $message\n Newsletter \n $newsletter";

If you are interested to detect simple IR light blob through haar cascade, it will be very odd to do. Because simple IR blob does not have enough features to be trained through opencv like other objects (face, eyes,nose etc). Because IR is just a simple light having only one feature of brightness in my point of view. But if you want to learn how to train a classifier following link will help you alot.

http://note.sonots.com/SciSoftware/haartraining.html

And if you just want to detect IR blob, then you have two more possibilities, one is you go for DIP algorithms to detect bright region and the other one which I recommend you is you can use an IR cam which just pass the IR blob and you can detect easily the IR blob by using opencv blob functiuons. If you think an IR cam is expansive, you can make simple webcam to an IR cam by removing IR blocker (if any) and add visible light blocker i.e negative film, floppy material or any other. You can check the following link to convert simple webcam to IR cam.

Reportlab. There is an open source version, and a paid version which adds the Report Markup Language (an alternative method of defining your document).

If there are no performance gains using a join, then I prefer Common Table Expressions (CTEs) for readability:

WITH subquery AS (
    SELECT address_id, customer, address, partn
    FROM  /* big hairy SQL */ ...
)
UPDATE dummy
SET customer = subquery.customer,
    address  = subquery.address,
    partn    = subquery.partn
FROM subquery
WHERE dummy.address_id = subquery.address_id;

IMHO a bit more modern.

No you can not but you may want to use input type number as a workaround. Look at the following example:

<input type="number" min="1900" max="2099" step="1" value="2016" />

Java 5+ has all the tools you need for this kind of thing. You will want to:

1. Put all your Producers in one ExecutorService;
2. Put all your Consumers in another ExecutorService;
3. If necessary, communicate between the two using a BlockingQueue.

I say "if necessary" for (3) because from my experience it's an unnecessary step. All you do is submit new tasks to the consumer executor service. So:

final ExecutorService producers = Executors.newFixedThreadPool(100);
final ExecutorService consumers = Executors.newFixedThreadPool(100);
while (/* has more work */) {
  producers.submit(...);
}
producers.shutdown();
producers.awaitTermination(Long.MAX_VALUE, TimeUnit.NANOSECONDS);
consumers.shutdown();
consumers.awaitTermination(Long.MAX_VALUE, TimeUnit.NANOSECONDS);

So the producers submit directly to consumers.

I was having trouble getting intl to run using PHP 7.1.7 and PhpStorm on Windows 10. Based on other answers here I could tell it was a PATH/DLL dependency problem but I couldn't seem to find all of the required files even after (re-)installing the Visual C++ Redistributable.

I eventually went searching my C: drive for vcr*.dll and found a copy of vcruntime140.dll in my C:\Program Files\Mozilla Firefox directory. So, in addition to making these changes to php.ini:

extension_dir = "ext"
extension=php_intl.dll

I also set my runtime PATH to ONLY the PHP directory (in my case, C:\Program Files\PHP\7.1.7) and the Firefox directory (above) and it FINALLY worked! I know it needs more than just the vcruntime140.dll but the other required DLLs must be in the FF directory too (there are a few dozen but I didn't bother to figure out which ones are essential).

I started a process from a Windows Service over the Win32 API in the session from the user which is actually logged in (in Task Manager session 1 not 0). In this was we can get to know, which variable is the best.

For all 7 cases from the question above, the following are the results:

Path1: C:\Program Files (x86)\MyProgram
Path2: C:\Program Files (x86)\MyProgram
Path3: C:\Program Files (x86)\MyProgram\
Path4: C:\Windows\system32
Path5: C:\Windows\system32
Path6: file:\C:\Program Files (x86)\MyProgram
Path7: C:\Program Files (x86)\MyProgram

Perhaps it's helpful for some of you, doing the same stuff, when you search the best variable for your case.

Assuming you are using Windows forms, you could allow the user to select a row and in the delete key click event. It is recommended that you allow the user to select 1 row only and not a group of rows (myDataGridView.MultiSelect = false)

Private Sub pbtnDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelete.Click

        If myDataGridView.SelectedRows.Count > 0 Then
            'you may want to add a confirmation message, and if the user confirms delete
            myDataGridView.Rows.Remove(myDataGridView.SelectedRows(0))
        Else
            MessageBox.Show("Select 1 row before you hit Delete")
        End If

    End Sub

Note that this will not delete the row form the database until you perform the delete in the database.

Try setting the charset on your Content-Type:

httpCon.setRequestProperty( "Content-Type", "multipart/form-data; charset=UTF-8; boundary=" + boundary );

Extract characters from a string:

var str = "Hello world!";
var res = str.substring(1,4);

The result of res will be:

ell

http://www.w3schools.com/jsref/jsref_substring.asp

$('.dep_buttons').mouseover(function(){
    $(this).text().substring(0,25);
    if($(this).text().length > 30) {
        $(this).stop().animate({height:"150px"},150);
    }
    $(".dep_buttons").mouseout(function(){
        $(this).stop().animate({height:"40px"},150);
    });
});

You can also, using jQuery, attach an animation to html,body of the document via:

$("html,body").animate({scrollTop:$("#div-id")[0].offsetTop}, 1000);

which will result in a smooth scroll to the top of the div with id "div-id".

create a filter.js and you can make this as reusable

angular.module('yourmodule').filter('date', function($filter)
{
    return function(input)
    {
        if(input == null){ return ""; }
        var _date = $filter('date')(new Date(input), 'dd/MM/yyyy');
        return _date.toUpperCase();
    };
});

view

<span>{{ d.time | date }}</span>

or in controller

var filterdatetime = $filter('date')( yourdate );

Starting with VB.NET 10, implicit line continuation is supported for a number of syntax elements (see Statements in Visual Basic: Continuing a Statement over Multiple Lines). The concatenation operator (&) is in the list of syntax elements, that support implicit line continuation. Interspersed comments are supported as well, so your second example could be rewritten as:

dim createArticle as string = 
    "Create table article " &
    "    (articleID int " &           ' Comment for articleID
    "    ,articleName varchar(50) " & ' Comment for articleName
    "    )"

Implicit line continuation also works for query operators, with a few restrictions:

Before and after query operators (Aggregate, Distinct, From, Group By, Group Join, Join, Let, Order By, Select, Skip, Skip While, Take, Take While, Where, In, Into, On, Ascending, and Descending). You cannot break a line between the keywords of query operators that are made up of multiple keywords (Order By, Group Join, Take While, and Skip While).

Again, interspersed comments are allowed, so your first example can be rewritten as:

dim results = from a in articles
              where a.articleID = 4  ' articleID - now perfectly legal
              select a.articleName

I want to expand on my readability comment above.

Again, I completely agree with readability overriding other (performance-insignificant) concerns.

What I would like to point out is the brain interprets "positive" faster than it does "negative". E.g., "stop" vs. "do not go" (a rather lousy example due to the difference in number of words).

So given a choice:

if a == b
    (do this)
else
    (do that)

is preferable to the functionally-equivalent:

if a != b
    (do that)
else
    (do this)

Less readability/understandability leads to more bugs. Perhaps not in initial coding, but the (not as smart as you!) maintenance changes...

$date = strtotime('2016-2-3');
$date = date('l', $date);
var_dump($date)

(i added format 'l' so it will return full name of day)

You have not used float:left command for your text.

use this

<div ng-class="{states}[condition]"></div>

for example if the condition is [2 == 2], states are {true: '...', false: '...'}

<div ng-class="{true: 'ClassA', false: 'ClassB'}[condition]"></div>

For those looking a more modern approach, you can use the fetch API. The following example shows how to download a spreadsheet file. It is easily done with the following code.

fetch(url, {
    body: JSON.stringify(data),
    method: 'POST',
    headers: {
        'Content-Type': 'application/json; charset=utf-8'
    },
})
.then(response => response.blob())
.then(response => {
    const blob = new Blob([response], {type: 'application/application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'});
    const downloadUrl = URL.createObjectURL(blob);
    const a = document.createElement("a");
    a.href = downloadUrl;
    a.download = "file.xlsx";
    document.body.appendChild(a);
    a.click();
})

I believe this approach to be much easier to understand than other XMLHttpRequest solutions. Also, it has a similar syntax to the jQuery approach, without the need to add any additional libraries.

Of course, I would advise checking to which browser you are developing, since this new approach won't work on IE. You can find the full browser compatibility list on the following link.

Important: In this example I am sending a JSON request to a server listening on the given url. This url must be set, on my example I am assuming you know this part. Also, consider the headers needed for your request to work. Since I am sending a JSON, I must add the Content-Type header and set it to application/json; charset=utf-8, as to let the server know the type of request it will receive.

Using equals() LocalDate does override equals:

int compareTo0(LocalDate otherDate) {
    int cmp = (year - otherDate.year);
    if (cmp == 0) {
        cmp = (month - otherDate.month);
        if (cmp == 0) {
            cmp = (day - otherDate.day);
        }
    }
    return cmp;
}

If you are not happy with the result of equals(), you are good using the predefined methods of LocalDate.

• isAfter()
• isBefore()
• isEqual()

Notice that all of those method are using the compareTo0() method and just check the cmp value. if you are still getting weird result (which you shouldn't), please attach an example of input and output

Subplot Colorbar

For subplots with scatter, you can trick a colorbar onto your axes by building the "mappable" with the help of a secondary figure and then adding it to your original plot.

As a continuation of the above example:

import numpy as np
import matplotlib.pyplot as plt

x = np.arange(10)
y = x
t = x
fig, (ax1, ax2) = plt.subplots(1, 2)
ax1.scatter(x, y, c=t, cmap='viridis')
ax2.scatter(x, y, c=t, cmap='viridis_r')


# Build your secondary mirror axes:
fig2, (ax3, ax4) = plt.subplots(1, 2)

# Build maps that parallel the color-coded data
# NOTE 1: imshow requires a 2-D array as input
# NOTE 2: You must use the same cmap tag as above for it match
map1 = ax3.imshow(np.stack([t, t]),cmap='viridis')
map2 = ax4.imshow(np.stack([t, t]),cmap='viridis_r')

# Add your maps onto your original figure/axes
fig.colorbar(map1, ax=ax1)
fig.colorbar(map2, ax=ax2)
plt.show()

Note that you will also output a secondary figure that you can ignore.

The most simple way is to use find_element_by_class_name('class_name')

locale command with no arguments will print the values of all of the relevant environment variables except for LANGUAGE.

For current encoding:

locale charmap

For available locales:

locale -a

For available encodings:

locale -m

There is no Javascript API to send ping frames or receive pong frames. This is either supported by your browser, or not. There is also no API to enable, configure or detect whether the browser supports and is using ping/pong frames. There was discussion about creating a Javascript ping/pong API for this. There is a possibility that pings may be configurable/detectable in the future, but it is unlikely that Javascript will be able to directly send and receive ping/pong frames.

However, if you control both the client and server code, then you can easily add ping/pong support at a higher level. You will need some sort of message type header/metadata in your message if you don't have that already, but that's pretty simple. Unless you are planning on sending pings hundreds of times per second or have thousands of simultaneous clients, the overhead is going to be pretty minimal to do it yourself.

I came up with this too... then I solve it by putting the database information directly in " database.php " In your case, I would change the information like this

mysql' => [
        'driver'    => 'mysql',
        'host'      => 'localhost',
        'database'  => 'wdcollect',
        'username'  => 'root',
        'password'  => '',
        'charset'   => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix'    => '',
        'strict'    => false,
    ],

and don't forget to change your setting in XAMPP's config.inc

['auth_type'] = 'config';
['Servers'][$i]['user'] = 'root';
['Servers'][$i]['password'] = '';
['AllowNoPassword'] = true;

in 1.x there used to be things DataTables couldn't do which DataSets could (don't remember exactly what). All that was changed in 2.x. My guess is that's why a lot of examples still use DataSets. DataTables should be quicker as they are more lightweight. If you're only pulling a single resultset, its your best choice between the two.

No, this is not possible. In documents that make use of CSS, an inline style attribute can only contain property declarations; the same set of statements that appears in each ruleset in a stylesheet. From the Style Attributes spec:

The value of the style attribute must match the syntax of the contents of a CSS declaration block (excluding the delimiting braces), whose formal grammar is given below in the terms and conventions of the CSS core grammar:

declaration-list
  : S* declaration? [ ';' S* declaration? ]*
  ;

Neither selectors (including pseudo-elements), nor at-rules, nor any other CSS construct are allowed.

Think of inline styles as the styles applied to some anonymous super-specific ID selector: those styles only apply to that one very element with the style attribute. (They take precedence over an ID selector in a stylesheet too, if that element has that ID.) Technically it doesn't work like that; this is just to help you understand why the attribute doesn't support pseudo-class or pseudo-element styles (it has more to do with how pseudo-classes and pseudo-elements provide abstractions of the document tree that can't be expressed in the document language).

Note that inline styles participate in the same cascade as selectors in rule sets, and take highest precedence in the cascade (!important notwithstanding). So they take precedence even over pseudo-class states. Allowing pseudo-classes or any other selectors in inline styles would possibly introduce a new cascade level, and with it a new set of complications.

Note also that very old revisions of the Style Attributes spec did originally propose allowing this, however it was scrapped, presumably for the reason given above, or because implementing it was not a viable option.

I was trying to find the meaning of GRANT USAGE on *.* TO and found here. I can clarify that GRANT USAGE on *.* TO user IDENTIFIED BY PASSWORD password will be granted when you create the user with the following command (CREATE):

CREATE USER 'user'@'localhost' IDENTIFIED BY 'password'; 

When you grant privilege with GRANT, new privilege s will be added on top of it.

Following is the code snippet which shows better way to handle the response body as a String whether it's a valid response or error response for the HTTP POST request:

BufferedReader reader = null;
OutputStream os = null;
String payload = "";
try {
    URL url1 = new URL("YOUR_URL");
    HttpURLConnection postConnection = (HttpURLConnection) url1.openConnection();
    postConnection.setRequestMethod("POST");
    postConnection.setRequestProperty("Content-Type", "application/json");
    postConnection.setDoOutput(true);
    os = postConnection.getOutputStream();
    os.write(eventContext.getMessage().getPayloadAsString().getBytes());
    os.flush();

    String line;
    try{
        reader = new BufferedReader(new InputStreamReader(postConnection.getInputStream()));
    }
    catch(IOException e){
        if(reader == null)
            reader = new BufferedReader(new InputStreamReader(postConnection.getErrorStream()));
    }
    while ((line = reader.readLine()) != null)
        payload += line.toString();
}       
catch (Exception ex) {
            log.error("Post request Failed with message: " + ex.getMessage(), ex);
} finally {
    try {
        reader.close();
        os.close();
    } catch (IOException e) {
        log.error(e.getMessage(), e);
        return null;
    }
}

It looks like there's something else called Afisho_rankimin in your DB so the function is not being created. Try calling your function something else. E.g.

CREATE FUNCTION dbo.Afisho_rankimin1(@emri_rest int)
RETURNS int
AS
   BEGIN
       Declare @rankimi int
       Select @rankimi=dbo.RESTORANTET.Rankimi
       From RESTORANTET
       Where  dbo.RESTORANTET.ID_Rest=@emri_rest
       RETURN @rankimi
  END
  GO

Note that you need to call this only once, not every time you call the function. After that try calling

SELECT dbo.Afisho_rankimin1(5) AS Rankimi 

@Override
public Map<String, String> getHeaders() throws AuthFailureError {
    HashMap<String, String> headers = new HashMap<String, String>();
    headers.put("Content-Type", "application/json; charset=utf-8");
    return headers;
}

You need to add Content-Type to the header.

Try this solution:

Oz<-subset(data, data$Month==5,select=Ozone) # select ozone  value in the month of                 
                                             #May (i.e. Month = 5)
summary(T)                                   #gives caracteristics of table( contains 1 column of Ozone) including max, min ...

In command line it's better to use REG tool rather than REGEDIT:

REG IMPORT yourfile.reg

REG is designed for console mode, while REGEDIT is for graphical mode. This is why running regedit.exe /S yourfile.reg is a bad idea, since you will not be notified if the there's an error, whereas REG Tool will prompt:

>  REG IMPORT missing_file.reg

ERROR: Error opening the file. There may be a disk or file system error.

>  %windir%\System32\reg.exe /?

Just store the index generated in a variable, and then access the array using this varaible:

int idx = new Random().nextInt(fruits.length);
String random = (fruits[idx]);

P.S. I usually don't like generating new Random object per randoization - I prefer using a single Random in the program - and re-use it. It allows me to easily reproduce a problematic sequence if I later find any bug in the program.

According to this approach, I will have some variable Random r somewhere, and I will just use:

int idx = r.nextInt(fruits.length)

However, your approach is OK as well, but you might have hard time reproducing a specific sequence if you need to later on.

For global use, you may use:

$val = $_REQUEST['subject'];

and to add yo your session, simply

session_start();
$_SESSION['subject'] =  $val;

And you dont need jQuery in this case.

The error MethodNotAllowedHttpException means the route exists, but the HTTP method (GET) is wrong. You have to change it to POST:

Route::post('test/register', array('uses'=>'TestController@create'));

Also, you need to hash your passwords:

public function create()
{
    $user = new User;

    $user->username = Input::get('username');
    $user->email = Input::get('email');
    $user->password = Hash::make(Input::get('password'));
    $user->save();

    return Redirect::back();
}

And I removed the line:

$user= Input::all();

Because in the next command you replace its contents with

$user = new User;

To debug your Input, you can, in the first line of your controller:

dd( Input::all() );

It will display all fields in the input.

You can try

member.substr(member.length-2);

I think you are looking for this function:

http://doc.qt.io/qt-5/qdatetime.html#toTime_t

uint QDateTime::toTime_t () const

Returns the datetime as the number of seconds that have passed since 1970-01-01T00:00:00, > Coordinated Universal Time (Qt::UTC).

On systems that do not support time zones, this function will behave as if local time were Qt::UTC.

See also setTime_t().

Brad Oyler's answer is correct. But you will only receive one event. If you need to get constant updates of the scroll position, you should set the scrollEventThrottle prop, like so:

<ScrollView onScroll={this.handleScroll} scrollEventThrottle={16} >
  <Text>
    Be like water my friend …
  </Text>
</ScrollView>

And the event handler:

handleScroll: function(event: Object) {
  console.log(event.nativeEvent.contentOffset.y);
},

Be aware that you might run into performance issues. Adjust the throttle accordingly. 16 gives you the most updates. 0 only one.

LOAD DATA INFILE '/home/userlap/data2/worldcitiespop.txt' INTO TABLE cc FIELDS TERMINATED BY ','LINES TERMINATED BY '\r \n' IGNORE 1 LINES;

• IGNORE 1 LINES to skip over an initial header line containing column names
• FIELDS TERMINATED BY ',' is to read the comma-delimited file
• If you have generated the text file on a Windows system, you might have to use LINES TERMINATED BY '\r\n' to read the file properly, because Windows programs typically use two characters as a line terminator. Some programs, such as WordPad, might use \r as a line terminator when writing files. To read such files, use LINES TERMINATED BY '\r'.

Highly recommend you check out PDF.js which is able to render PDF documents in a standard a WebView component.

Also see https://github.com/loosemoose/androidpdf for a sample implementation of this.

You forgot the .class:

if (value.getClass() == Integer.class) {
    System.out.println("This is an Integer");
} 
else if (value.getClass() == String.class) {
    System.out.println("This is a String");
}
else if (value.getClass() == Float.class) {
    System.out.println("This is a Float");
}

Note that this kind of code is usually the sign of a poor OO design.

Also note that comparing the class of an object with a class and using instanceof is not the same thing. For example:

"foo".getClass() == Object.class

is false, whereas

"foo" instanceof Object

is true.

Whether one or the other must be used depends on your requirements.

I've avoided using setTimeout by using a global function:

EDIT NOTE: I've updated the following helper scripts and created a class that easier/simpler to use; check it out here ::: https://github.com/tjmehta/fbExec.js

window.fbAsyncInit = function() {
    FB.init({
        //...
    });
    window.fbApiInit = true; //init flag
    if(window.thisFunctionIsCalledAfterFbInit)
        window.thisFunctionIsCalledAfterFbInit();
};

fbEnsureInit will call it's callback after FB.init

function fbEnsureInit(callback){
  if(!window.fbApiInit) {
    window.thisFunctionIsCalledAfterFbInit = callback; //find this in index.html
  }
  else{
    callback();
  }
}

fbEnsureInitAndLoginStatus will call it's callback after FB.init and after FB.getLoginStatus

function fbEnsureInitAndLoginStatus(callback){
  runAfterFbInit(function(){
    FB.getLoginStatus(function(response){
      if (response.status === 'connected') {
        // the user is logged in and has authenticated your
        // app, and response.authResponse supplies
        // the user's ID, a valid access token, a signed
        // request, and the time the access token
        // and signed request each expire
        callback();

      } else if (response.status === 'not_authorized') {
        // the user is logged in to Facebook,
        // but has not authenticated your app

      } else {
        // the user isn't logged in to Facebook.

      }
    });
  });
}

fbEnsureInit example usage:

(FB.login needs to be run after FB has been initialized)

fbEnsureInit(function(){
    FB.login(
       //..enter code here
    );
});

fbEnsureInitAndLogin example usage:

(FB.api needs to be run after FB.init and FB user must be logged in.)

fbEnsureInitAndLoginStatus(function(){
    FB.api(
       //..enter code here
    );
});

You can also try:

INSERT IGNORE
  INTO table_1 
SELECT *
  FROM table_2
     ;

which allows those rows in table_1 to supersede those in table_2 that have a matching primary key, while still inserting rows with new primary keys.

Alternatively,

REPLACE
   INTO table_1
 SELECT *
   FROM table_2
      ;

will update those rows already in table_1 with the corresponding row from table_2, while inserting rows with new primary keys.

If you're using Python 3 then you must install as follows:

sudo apt-get update
sudo apt-get install python3-tk

Tkinter for Python 2 (python-tk) is different from Python 3's (python3-tk).

You have two options to get this done. (As far as i know)

1. Option A: Make your text field read only. It can be done as follows.

2. Option B: Change the curser onfocus. Set ti to blur. it can be done by setting up the attribute onfocus="this.blur()" to your date picker text field.

Ex: <input type="text" name="currentDate" id="currentDate" onfocus="this.blur()" readonly/>

At a minimum you are going to need to know the column delimiter.

If issue remains even after updating dependency version, then delete everything present under

OpenJDK is a reference model and open source, while Oracle JDK is an implementation of the OpenJDK and is not open source. Oracle JDK is more stable than OpenJDK.

OpenJDK is released under GPL v2 license whereas Oracle JDK is licensed under Oracle Binary Code License Agreement.

OpenJDK and Oracle JDK have almost the same code, but Oracle JDK has more classes and some bugs fixed.

So if you want to develop enterprise/commercial software I would suggest to go for Oracle JDK, as it is thoroughly tested and stable.

I have faced lot of problems with application crashes using OpenJDK, which are fixed just by switching to Oracle JDK

I recommend using the following snippet as it works in all python versions (requires six):

from six.moves import reload_module
reload_module(module)

You really can't*:

Example is taken from this Java tutorial

Assume there are two types A and B such that B extends A. Then the following code is correct:

    B b = new B();
    A a = b;

The previous code is valid because B is a subclass of A. Now, what happens with List<A> and List<B>?

It turns out that List<B> is not a subclass of List<A> therefore we cannot write

    List<B> b = new ArrayList<>();
    List<A> a = b; // error, List<B> is not of type List<A>

Furthermore, we can't even write

    List<B> b = new ArrayList<>();
    List<A> a = (List<A>)b; // error, List<B> is not of type List<A>

*: To make the casting possible we need a common parent for both List<A> and List<B>: List<?> for example. The following is valid:

    List<B> b = new ArrayList<>();
    List<?> t = (List<B>)b;
    List<A> a = (List<A>)t;

You will, however, get a warning. You can suppress it by adding @SuppressWarnings("unchecked") to your method.

All I needed was this :

SimpleDateFormat sdf = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss");
sdf.setTimeZone(TimeZone.getTimeZone("GMT"));

SimpleDateFormat sdfLocal = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss");

try {
    String d = sdf.format(new Date());
    System.out.println(d);
    System.out.println(sdfLocal.parse(d));
} catch (Exception e) {
    e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
}

Output : slightly dubious, but I want only the date to be consistent

I ran into the issue where the class of 'selected' wasn't being added to my menu item. Turns out that you can't have a NavigateUrl on it for whatever reason.

Once I removed the NavigateUrl it applied the 'selected' css class to the a tag and I was able to apply the background style with:

div.menu ul li a.static.selected
{
    background-color: #bfcbd6 !important;
    color: #465c71 !important;
    text-decoration: none !important;
}

select email, count(*) as c FROM orders GROUP BY email

Repeat:

UIImage *img = [UIImage imageNamed:@"bg.png"];
view.backgroundColor = [UIColor colorWithPatternImage:img];

Stretched

UIImage *img = [UIImage imageNamed:@"bg.png"];
view.layer.contents = img.CGImage;

for a in soup("p",{'id':'pagination'})[0]("a",{'href': True}):
        if createunicode(a.text) in ['<','<']:
            links.append(a.attrMap['href'])
        else:
            continue

It works for me.

You must create a select element object from the drop down list.

 using OpenQA.Selenium.Support.UI;

 // select the drop down list
 var education = driver.FindElement(By.Name("education"));
 //create select element object 
 var selectElement = new SelectElement(education);

 //select by value
 selectElement.SelectByValue("Jr.High"); 
 // select by text
 selectElement.SelectByText("HighSchool");

More info here

This works for me (Excel 2013):

Public Sub StartExeWithArgument()
    Dim strProgramName As String
    Dim strArgument As String

    strProgramName = "C:\Program Files\Test\foobar.exe"
    strArgument = "/G"

    Call Shell("""" & strProgramName & """ """ & strArgument & """", vbNormalFocus)
End Sub

GitHub now has an import option that lets you choose whatever you want your new imported repository public or private

The package is not fully compatible with dotnetcore 2.0 for now.

eg, for 'Microsoft.AspNet.WebApi.Client' it maybe supported in version (5.2.4). See Consume new Microsoft.AspNet.WebApi.Client.5.2.4 package for details.

You could try the standard Client package as Federico mentioned.

If that still not work, then as a workaround you can only create a Console App (.Net Framework) instead of the .net core 2.0 console app.

Reference this thread: Microsoft.AspNet.WebApi.Client supported in .NET Core or not?

As has, to some extent, been mentioned before, an enum is a java class with the special condition that its definition must start with at least one "enum constant".

Apart from that, and that enums cant can't be extended or used to extend other classes, an enum is a class like any class and you use it by adding methods below the constant definitions:

public enum MySingleton {
    INSTANCE;

    public void doSomething() { ... }

    public synchronized String getSomething() { return something; }

    private String something;
}

You access the singleton's methods along these lines:

MySingleton.INSTANCE.doSomething();
String something = MySingleton.INSTANCE.getSomething();

The use of an enum, instead of a class, is, as has been mentioned in other answers, mostly about a thread-safe instantiation of the singleton and a guarantee that it will always only be one copy.

And, perhaps, most importantly, that this behavior is guaranteed by the JVM itself and the Java specification.

Here's a section from the Java specification on how multiple instances of an enum instance is prevented:

An enum type has no instances other than those defined by its enum constants. It is a compile-time error to attempt to explicitly instantiate an enum type. The final clone method in Enum ensures that enum constants can never be cloned, and the special treatment by the serialization mechanism ensures that duplicate instances are never created as a result of deserialization. Reflective instantiation of enum types is prohibited. Together, these four things ensure that no instances of an enum type exist beyond those defined by the enum constants.

Worth noting is that after the instantiation any thread-safety concerns must be handled like in any other class with the synchronized keyword etc.

From the git-branch manual page:

 git branch --contains <commit>

Only list branches which contain the specified commit (HEAD if not specified). Implies --list.

 git branch -r --contains <commit>

Lists remote tracking branches as well (as mentioned in user3941992's answer below) that is "local branches that have a direct relationship to a remote branch".

As noted by Carl Walsh, this applies only to the default refspec

fetch = +refs/heads/*:refs/remotes/origin/*

If you need to include other ref namespace (pull request, Gerrit, ...), you need to add that new refspec, and fetch again:

git config --add remote.origin.fetch "+refs/pull/*/head:refs/remotes/origin/pr/*"
git fetch
git branch -r --contains <commit>

See also this git ready article.

The --contains tag will figure out if a certain commit has been brought in yet into your branch. Perhaps you’ve got a commit SHA from a patch you thought you had applied, or you just want to check if commit for your favorite open source project that reduces memory usage by 75% is in yet.

$ git log -1 tests

    Green all around, finally.

$ git branch --contains d590f2
  tests
* master

Note: if the commit is on a remote tracking branch, add the -a option.
(as MichielB comments below)

git branch -a --contains <commit>

MatrixFrog comments that it only shows which branches contain that exact commit.
If you want to know which branches contain an "equivalent" commit (i.e. which branches have cherry-picked that commit) that's git cherry:

Because git cherry compares the changeset rather than the commit id (sha1), you can use git cherry to find out if a commit you made locally has been applied <upstream> under a different commit id.
For example, this will happen if you’re feeding patches <upstream> via email rather than pushing or pulling commits directly.

           __*__*__*__*__> <upstream>
          /
fork-point
          \__+__+__-__+__+__-__+__> <head>

(Here, the commits marked '-' wouldn't show up with git cherry, meaning they are already present in <upstream>.)

@Valid in itself has nothing to do with Spring. It's part of Bean Validation specification(there are several of them, the latest one being JSR 380 as of second half of 2017), but @Valid is very old and derives all the way from JSR 303.

As we all know, Spring is very good at providing integration with all different JSRs and java libraries in general(think of JPA, JTA, Caching, etc.) and of course those guys took care of validation as well. One of the key components that facilitates this is MethodValidationPostProcessor.

Trying to answer your question - @Valid is very handy for so called validation cascading when you want to validate a complex graph and not just a top-level elements of an object. Every time you want to go deeper, you have to use @Valid. That's what JSR dictates. Spring will comply with that with some minor deviations(for example I tried putting @Validated instead of @Valid on RestController method and validation works, but the same will not apply for a regular "service" beans).

Python dictionaries are unordered. If you want an ordered dictionary, use collections.OrderedDict

In your case, sort the dict by key before plotting,

import matplotlib.pylab as plt

lists = sorted(d.items()) # sorted by key, return a list of tuples

x, y = zip(*lists) # unpack a list of pairs into two tuples

plt.plot(x, y)
plt.show()

Here is the result.

Integer.valueOf(s)

is similar to

new Integer(Integer.parseInt(s))

The difference is valueOf() returns an Integer, and parseInt() returns an int (a primitive type). Also note that valueOf() can return a cached Integer instance, which can cause confusing results where the result of == tests seem intermittently correct. Before autoboxing there could be a difference in convenience, after java 1.5 it doesn't really matter.

Moreover, Integer.parseInt(s) can take primitive datatype as well.

All your problems are that you are mixing content type negotiation with parameter passing. They are things at different levels. More specific, for your question 2, you constructed the response header with the media type your want to return. The actual content negotiation is based on the accept media type in your request header, not response header. At the point the execution reaches the implementation of the method getPersonFormat, I am not sure whether the content negotiation has been done or not. Depends on the implementation. If not and you want to make the thing work, you can overwrite the request header accept type with what you want to return.

return new ResponseEntity<>(PersonFactory.createPerson(), httpHeaders, HttpStatus.OK);

I am working MacOS 10.10. I have updated gcc to version 4.9 to make it work.

I understand this question might have a React-specific cause, but it shows up first in search results for "Typeerror: Failed to fetch" and I wanted to lay out all possible causes here.

The Fetch spec lists times when you throw a TypeError from the Fetch API: https://fetch.spec.whatwg.org/#fetch-api

Relevant passages as of January 2021 are below. These are excerpts from the text.

4.6 HTTP-network fetch

To perform an HTTP-network fetch using request with an optional credentials flag, run these steps:
...
16. Run these steps in parallel:
...
2. If aborted, then:
...
3. Otherwise, if stream is readable, error stream with a TypeError.

To append a name/value name/value pair to a Headers object (headers), run these steps:

1. Normalize value.
2. If name is not a name or value is not a value, then throw a TypeError.
3. If headers’s guard is "immutable", then throw a TypeError.

Filling Headers object headers with a given object object:

To fill a Headers object headers with a given object object, run these steps:

1. If object is a sequence, then for each header in object:
   1. If header does not contain exactly two items, then throw a TypeError.

Method steps sometimes throw TypeError:

The delete(name) method steps are:

1. If name is not a name, then throw a TypeError.
2. If this’s guard is "immutable", then throw a TypeError.

The get(name) method steps are:

1. If name is not a name, then throw a TypeError.
2. Return the result of getting name from this’s header list.

The has(name) method steps are:

1. If name is not a name, then throw a TypeError.

The set(name, value) method steps are:

1. Normalize value.
2. If name is not a name or value is not a value, then throw a TypeError.
3. If this’s guard is "immutable", then throw a TypeError.

To extract a body and a Content-Type value from object, with an optional boolean keepalive (default false), run these steps:
...
5. Switch on object:
...
ReadableStream
If keepalive is true, then throw a TypeError.
If object is disturbed or locked, then throw a TypeError.

In the section "Body mixin" if you are using FormData there are several ways to throw a TypeError. I haven't listed them here because it would make this answer very long. Relevant passages: https://fetch.spec.whatwg.org/#body-mixin

In the section "Request Class" the new Request(input, init) constructor is a minefield of potential TypeErrors:

The new Request(input, init) constructor steps are:
...
6. If input is a string, then:
...
2. If parsedURL is a failure, then throw a TypeError.
3. IF parsedURL includes credentials, then throw a TypeError.
...
11. If init["window"] exists and is non-null, then throw a TypeError.
...
15. If init["referrer" exists, then:
...
1. Let referrer be init["referrer"].
2. If referrer is the empty string, then set request’s referrer to "no-referrer".
3. Otherwise:
1. Let parsedReferrer be the result of parsing referrer with baseURL.
2. If parsedReferrer is failure, then throw a TypeError.
...
18. If mode is "navigate", then throw a TypeError.
...
23. If request's cache mode is "only-if-cached" and request's mode is not "same-origin" then throw a TypeError.
...
27. If init["method"] exists, then:
...
2. If method is not a method or method is a forbidden method, then throw a TypeError.
...
32. If this’s request’s mode is "no-cors", then:
1. If this’s request’s method is not a CORS-safelisted method, then throw a TypeError.
...
35. If either init["body"] exists and is non-null or inputBody is non-null, and request’s method is GET or HEAD, then throw a TypeError.
...
38. If body is non-null and body's source is null, then:
1. If this’s request’s mode is neither "same-origin" nor "cors", then throw a TypeError.
...
39. If inputBody is body and input is disturbed or locked, then throw a TypeError.

The clone() method steps are:

1. If this is disturbed or locked, then throw a TypeError.

In the Response class:

The new Response(body, init) constructor steps are:
...
2. If init["statusText"] does not match the reason-phrase token production, then throw a TypeError.
...
8. If body is non-null, then:
1. If init["status"] is a null body status, then throw a TypeError.
...

The static redirect(url, status) method steps are:
...
2. If parsedURL is failure, then throw a TypeError.

The clone() method steps are:

1. If this is disturbed or locked, then throw a TypeError.

In section "The Fetch method"

The fetch(input, init) method steps are:
...
9. Run the following in parallel:
To process response for response, run these substeps:
...
3. If response is a network error, then reject p with a TypeError and terminate these substeps.

In addition to these potential problems, there are some browser-specific behaviors which can throw a TypeError. For instance, if you set keepalive to true and have a payload > 64 KB you'll get a TypeError on Chrome, but the same request can work in Firefox. These behaviors aren't documented in the spec, but you can find information about them by Googling for limitations for each option you're setting in fetch.

I actually built a Chrome extension that does exactly this, and for all web pages. The source code is on GitHub.

I find three bugs with Trello's approach, which I know because I've faced them myself :)

The copy doesn't work in these scenarios:

1. If you already have Ctrl pressed and then hover a link and hit C, the copy doesn't work.
2. If your cursor is in some other text field in the page, the copy doesn't work.
3. If your cursor is in the address bar, the copy doesn't work.

I solved #1 by always having a hidden span, rather than creating one when user hits Ctrl/Cmd.

I solved #2 by temporarily clearing the zero-length selection, saving the caret position, doing the copy and restoring the caret position.

I haven't found a fix for #3 yet :) (For information, check the open issue in my GitHub project).

I have been having the same problem. I followed Bruno's advice to you and found that adding a KeyListener just to the "first" button in the JFrame (ie, on the top left) did the trick. But I agree with you it is kind of an unsettling solution. So I fiddled around and discovered a neater way to fix it. Just add the line

myChildOfJFrame.requestFocusInWindow();

to your main method, after you've created your instance of your subclass of JFrame and set it visible.

For simple example,
http://www.helloandroid.com/tutorials/how-download-fileimage-url-your-device

You will have to use httpClient and download the image (cache it if required) ,

solution offered for displaying images in listview, essentially same code(check the code where imageview is set from url) for displaying.

Lazy load of images in ListView

I understand this is an old thread. I have faced the same issue and wanted to convert the .pynb file to .py file via command line.

My search took me to ipynb-py-convert

By following below steps I was able to get .py file

1. Install "pip install ipynb-py-convert"
2. Go to the directory where the ipynb file is saved via command prompt
3. Enter the command

> ipynb-py-convert YourFileName.ipynb YourFilename.py

Eg:. ipynb-py-convert getting-started-with-kaggle-titanic-problem.ipynb getting-started-with-kaggle-titanic-problem.py

Above command will create a python script with the name "YourFileName.py" and as per our example it will create getting-started-with-kaggle-titanic-problem.py file

Normal answer for this question if you really want to get something like content//media/external/video/media/18576 (e.g. for your video mp4 absolute path) and not just file///storage/emulated/0/DCIM/Camera/20141219_133139.mp4:

MediaScannerConnection.scanFile(this,
          new String[] { file.getAbsolutePath() }, null,
          new MediaScannerConnection.OnScanCompletedListener() {
      public void onScanCompleted(String path, Uri uri) {
          Log.i("onScanCompleted", uri.getPath());
      }
 });

Accepted answer is wrong (cause it will not return content//media/external/video/media/*)

Uri.fromFile(file).toString() only returns something like file///storage/emulated/0/* which is a simple absolute path of a file on the sdcard but with file// prefix (scheme)

You can also get content uri using MediaStore database of Android

TEST (what returns Uri.fromFile and what returns MediaScannerConnection):

File videoFile = new File("/storage/emulated/0/video.mp4");

Log.i(TAG, Uri.fromFile(videoFile).toString());

MediaScannerConnection.scanFile(this, new String[] { videoFile.getAbsolutePath() }, null,
        (path, uri) -> Log.i(TAG, uri.toString()));

Output:

I/Test: file:///storage/emulated/0/video.mp4

I/Test: content://media/external/video/media/268927

Use the rawurlencode function instead.

range() can only work with integers, but dividing with the / operator always results in a float value:

>>> 450 / 10
45.0
>>> range(450 / 10)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'float' object cannot be interpreted as an integer

Make the value an integer again:

for i in range(int(c / 10)):

or use the // floor division operator:

for i in range(c // 10):

Depending on what you want to achieve with the removed scroll you could just fix the element that you want to remove scroll from (on click, or whatever other trigger you'd like to temporarily deactivate scroll)

I was searching around for a "temp no scroll" solution and for my needs, this solved it

make a class

.fixed{
    position: fixed;
}

then with Jquery

var someTrigger = $('#trigger'); //a trigger button
var contentContainer = $('#content'); //element I want to temporarily remove scroll from

contentContainer.addClass('notfixed'); //make sure that the element has the "notfixed" class

//Something to trigger the fixed positioning. In this case we chose a button.
someTrigger.on('click', function(){

    if(contentContainer.hasClass('notfixed')){
        contentContainer.removeClass('notfixed').addClass('fixed');

    }else if(contentContainer.hasClass('fixed')){
        contentContainer.removeClass('fixed').addClass('notfixed');
    };
});

I found that this was a simple enough solution that works well on all browsers, and also makes for simple use on portable devices (i.e. iPhones, tablets etc). Since the element is temporarily fixed, there is no scroll :)

NOTE! Depending on the placement of your "contentContainer" element you might need to adjust it from the left. Which can easily be done by adding a css left value to that element when the fixed class is active

contentContainer.css({
    'left': $(window).width() - contentContainer.width()/2 //This would result in a value that is the windows entire width minus the element we want to "center" divided by two (since it's only pushed from one side)
});

To name a few we can use redux-react-session which is having good API for session management like, initSessionService, refreshFromLocalStorage, checkAuth and many other. It also provide some advanced functionality like Immutable JS.

Alternatively we can leverage react-web-session which provides options like callback and timeout.

It is called the conditional operator.

You can replace it with:

int qempty(){ 
    if (f == r) return 1;
    else return 0;
}

The Decision between Member and Non-member

The binary operators = (assignment), [] (array subscription), -> (member access), as well as the n-ary () (function call) operator, must always be implemented as member functions, because the syntax of the language requires them to.

Other operators can be implemented either as members or as non-members. Some of them, however, usually have to be implemented as non-member functions, because their left operand cannot be modified by you. The most prominent of these are the input and output operators << and >>, whose left operands are stream classes from the standard library which you cannot change.

For all operators where you have to choose to either implement them as a member function or a non-member function, use the following rules of thumb to decide:

1. If it is a unary operator, implement it as a member function.
2. If a binary operator treats both operands equally (it leaves them unchanged), implement this operator as a non-member function.
3. If a binary operator does not treat both of its operands equally (usually it will change its left operand), it might be useful to make it a member function of its left operand’s type, if it has to access the operand's private parts.

Of course, as with all rules of thumb, there are exceptions. If you have a type

enum Month {Jan, Feb, ..., Nov, Dec}

and you want to overload the increment and decrement operators for it, you cannot do this as a member functions, since in C++, enum types cannot have member functions. So you have to overload it as a free function. And operator<() for a class template nested within a class template is much easier to write and read when done as a member function inline in the class definition. But these are indeed rare exceptions.

(However, if you make an exception, do not forget the issue of const-ness for the operand that, for member functions, becomes the implicit this argument. If the operator as a non-member function would take its left-most argument as a const reference, the same operator as a member function needs to have a const at the end to make *this a const reference.)

Continue to Common operators to overload.

You need to specify the minimum width of the field.

String.format("%" + numberOfSpaces + "s", ""); 

Why do you want to generate a String of spaces of a certain length.

If you want a column of this length with values then you can do:

String.format("%" + numberOfSpaces + "s", "Hello"); 

which gives you numberOfSpaces-5 spaces followed by Hello. If you want Hello to appear on the left then add a minus sign in before numberOfSpaces.

You have to allocate the buffer with mallock, and give the read write the pointer to it.

#include <unistd.h>
#include <stdlib.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
int main(){
    ssize_t nrd;
    int fd; 
    int fd1;

    char* buffer = malloc(100*sizeof(char));
    fd = open("bli.txt", O_RDONLY);
    fd1 = open("bla.txt", O_CREAT | O_WRONLY, S_IRUSR | S_IWUSR);
    while (nrd = read(fd,buffer,sizeof(buffer))) {
        write(fd1,buffer,nrd);
    }   

    close(fd);
    close(fd1);
    free(buffer);
    return 0;
}

Make sure that the rad file exists and contains something. It's not perfect but it works.

In your IntelliJ idea find tools.jar replace it with tools.jar from yout JDK8

    public String encrypt(String str) {
        try {
            // Encode the string into bytes using utf-8
            byte[] utf8 = str.getBytes("UTF8");

            // Encrypt
            byte[] enc = ecipher.doFinal(utf8);

            // Encode bytes to base64 to get a string
            return new sun.misc.BASE64Encoder().encode(enc);
        } catch (javax.crypto.BadPaddingException e) {
        } catch (IllegalBlockSizeException e) {
        } catch (UnsupportedEncodingException e) {
        } catch (java.io.IOException e) {
        }
        return null;
    }

    public String decrypt(String str) {
        try {
            // Decode base64 to get bytes
            byte[] dec = new sun.misc.BASE64Decoder().decodeBuffer(str);

            // Decrypt
            byte[] utf8 = dcipher.doFinal(dec);

            // Decode using utf-8
            return new String(utf8, "UTF8");
        } catch (javax.crypto.BadPaddingException e) {
        } catch (IllegalBlockSizeException e) {
        } catch (UnsupportedEncodingException e) {
        } catch (java.io.IOException e) {
        }
        return null;
    }
}

Here's an example that uses the class:

try {
    // Generate a temporary key. In practice, you would save this key.
    // See also Encrypting with DES Using a Pass Phrase.
    SecretKey key = KeyGenerator.getInstance("DES").generateKey();

    // Create encrypter/decrypter class
    DesEncrypter encrypter = new DesEncrypter(key);

    // Encrypt
    String encrypted = encrypter.encrypt("Don't tell anybody!");

    // Decrypt
    String decrypted = encrypter.decrypt(encrypted);
} catch (Exception e) {
}

Use TextView inside a ScrollView to display messages with any no.of lines. User can't edit the text in this view as in EditText.

I think this is good for your requirement. Try it once.

You can change the default color and text size in XML file only if you want to fix them as below:

<TextView 
    android:id="@+id/tv"
    android:layout_width="fill_parent"
    android:layout_height="100px"
    android:textColor="#f00"
    android:textSize="25px"
    android:typeface="serif"
    android:textStyle="italic"/>

or if you want to change dynamically whenever you want use as below:

TextView textarea = (TextView)findViewById(R.id.tv);  // tv is id in XML file for TextView
textarea.setTextSize(20);
textarea.setTextColor(Color.rgb(0xff, 0, 0));
textarea.setTypeface(Typeface.SERIF, Typeface.ITALIC);

I have fast solution. Just create a file ArrayUtil.java

import java.util.ArrayList;
import java.util.Collection;
import org.json.JSONArray;
import org.json.JSONException;

public class ArrayUtil
{
    public static ArrayList<Object> convert(JSONArray jArr)
    {
        ArrayList<Object> list = new ArrayList<Object>();
        try {
            for (int i=0, l=jArr.length(); i<l; i++){
                 list.add(jArr.get(i));
            }
        } catch (JSONException e) {}

        return list;
    }

    public static JSONArray convert(Collection<Object> list)
    {
        return new JSONArray(list);
    }

}

Usage:

ArrayList<Object> list = ArrayUtil.convert(jArray);

or

JSONArray jArr = ArrayUtil.convert(list);

The existing answers are good and correct, however what if you need to undo the push but:

1. You want to keep the commits locally or you want to keep uncommitted changes
2. You don't know how many commits you just pushed

Use this command to revert the change to the ref:

git push -f origin refs/remotes/origin/<branch>@{1}:<branch>

Googling gives many sites... Debugging with the Eclipse platform for one.

The solution seems to be long accepted, but the solution could be improved, so if someone has a similar problem:

This is a classical application for multi-pattern-search-algorithms.

Java Pattern Search (with Matcher.find) is not qualified for doing that. Searching for exactly one keyword is optimized in java, searching for an or-expression uses the regex non deterministic automaton which is backtracking on mismatches. In worse case each character of the text will be processed l times (where l is the sum of the pattern lengths).

Single pattern search is better, but not qualified, too. One will have to start the whole search for every keyword pattern. In worse case each character of the text will be processed p times where p is the number of patterns.

Multi pattern search will process each character of the text exactly once. Algorithms suitable for such a search would be Aho-Corasick, Wu-Manber, or Set Backwards Oracle Matching. These could be found in libraries like Stringsearchalgorithms or byteseek.

// example with StringSearchAlgorithms

AhoCorasick stringSearch = new AhoCorasick(asList("123woods", "woods"));

CharProvider text = new StringCharProvider("I will come and meet you at the woods 123woods and all the woods", 0);

StringFinder finder = stringSearch.createFinder(text);

List<StringMatch> all = finder.findAll();

use this https://www.npmjs.com/package/json-stringify-safe

var stringify = require('json-stringify-safe');
var circularObj = {};
circularObj.circularRef = circularObj;
circularObj.list = [ circularObj, circularObj ];
console.log(stringify(circularObj, null, 2));


stringify(obj, serializer, indent, decycler)

parseInt($(this).css('marginBottom'), 10);

parseInt will automatically ignore the units.

For example:

var marginBottom = "10px";
marginBottom = parseInt(marginBottom, 10);
alert(marginBottom); // alerts: 10

That div.cell solution didn't actually work on my IPython, however luckily someone suggested a working solution for new IPythons:

Create a file ~/.ipython/profile_default/static/custom/custom.css (iPython) or ~/.jupyter/custom/custom.css (Jupyter) with content

.container { width:100% !important; }

Then restart iPython/Jupyter notebooks. Note that this will affect all notebooks.

Use calander and try this code.

Calendar calendar = Calendar.getInstance();         
calendar.add(Calendar.MONTH, 1);
calendar.set(Calendar.DATE, calendar.getActualMinimum(Calendar.DAY_OF_MONTH));
Date nextMonthFirstDay = calendar.getTime();
calendar.set(Calendar.DATE, calendar.getActualMaximum(Calendar.DAY_OF_MONTH));
Date nextMonthLastDay = calendar.getTime();

A question mark is a signifier for 'any type'. ? alone means

Any type extending Object (including Object)

while your example above means

Any type extending or implementing HasWord (including HasWord if HasWord is a non-abstract class)

I know this is an old one but it comes up top of Google and all the links provided now seem out of date.

This is the latest list of types Facebook accepts: https://developers.facebook.com/docs/reference/opengraph

If you don't use one of these then the type will default to 'website' which is best used for home pages/summarising a web site.

In answer to the OP you would now want to use a place which will allow you to add lat/long location details.

Let's say you have a class Person.

class Person
end

person = Person.new
person.name # => no method error

Obviously we never defined method name. Let's do that.

class Person
  def name
    @name # simply returning an instance variable @name
  end
end

person = Person.new
person.name # => nil
person.name = "Dennis" # => no method error

Aha, we can read the name, but that doesn't mean we can assign the name. Those are two different methods. The former is called reader and latter is called writer. We didn't create the writer yet so let's do that.

class Person
  def name
    @name
  end

  def name=(str)
    @name = str
  end
end

person = Person.new
person.name = 'Dennis'
person.name # => "Dennis"

Awesome. Now we can write and read instance variable @name using reader and writer methods. Except, this is done so frequently, why waste time writing these methods every time? We can do it easier.

class Person
  attr_reader :name
  attr_writer :name
end

Even this can get repetitive. When you want both reader and writer just use accessor!

class Person
  attr_accessor :name
end

person = Person.new
person.name = "Dennis"
person.name # => "Dennis"

Works the same way! And guess what: the instance variable @name in our person object will be set just like when we did it manually, so you can use it in other methods.

class Person
  attr_accessor :name

  def greeting
    "Hello #{@name}"
  end
end

person = Person.new
person.name = "Dennis"
person.greeting # => "Hello Dennis"

That's it. In order to understand how attr_reader, attr_writer, and attr_accessor methods actually generate methods for you, read other answers, books, ruby docs.

I converted the 'fast quick sort' algorithm to VBA, if anyone else wants it.

I have it optimized to run on an array of Int/Longs but it should be simple to convert it to one that works on arbitrary comparable elements.

Private Sub QuickSort(ByRef a() As Long, ByVal l As Long, ByVal r As Long)
    Dim M As Long, i As Long, j As Long, v As Long
    M = 4

    If ((r - l) > M) Then
        i = (r + l) / 2
        If (a(l) > a(i)) Then swap a, l, i '// Tri-Median Methode!'
        If (a(l) > a(r)) Then swap a, l, r
        If (a(i) > a(r)) Then swap a, i, r

        j = r - 1
        swap a, i, j
        i = l
        v = a(j)
        Do
            Do: i = i + 1: Loop While (a(i) < v)
            Do: j = j - 1: Loop While (a(j) > v)
            If (j < i) Then Exit Do
            swap a, i, j
        Loop
        swap a, i, r - 1
        QuickSort a, l, j
        QuickSort a, i + 1, r
    End If
End Sub

Private Sub swap(ByRef a() As Long, ByVal i As Long, ByVal j As Long)
    Dim T As Long
    T = a(i)
    a(i) = a(j)
    a(j) = T
End Sub

Private Sub InsertionSort(ByRef a(), ByVal lo0 As Long, ByVal hi0 As Long)
    Dim i As Long, j As Long, v As Long

    For i = lo0 + 1 To hi0
        v = a(i)
        j = i
        Do While j > lo0
            If Not a(j - 1) > v Then Exit Do
            a(j) = a(j - 1)
            j = j - 1
        Loop
        a(j) = v
    Next i
End Sub

Public Sub sort(ByRef a() As Long)
    QuickSort a, LBound(a), UBound(a)
    InsertionSort a, LBound(a), UBound(a)
End Sub

If the two controller is nested in One controller.
Then you can simply call:

$scope.parentmethod();  

Angular will search for parentmethod function starting with current scope and up until it will reach the rootScope.

There are several ways to do it, through settings or by deleting the cache.

Deleting the cache is the most versatile method. First, locate it:

On XP, it was located here:

C:\Documents and Settings\%USER%\Application Data\Subversion\auth\svn.simple\

On Vista, it was located here:

C:\Users\%USER%\AppData\Roaming\Subversion\auth\svn.simple\

Then look in those files with Notepad, and delete the one with your credentials.

Run the Gradle build with a command line argument --warning-mode=all to see what exactly the deprecated features are.

It will give you a detailed description of found issues with links to the Gradle docs for instructions how to fix your build.

Adding --stacktrace to that, you will also be able to pinpoint where the warning comes from, if it's triggered by outdated code in one of the plugins and not your build script.

G++ does support C++14 both via -std=c++14 and -std=c++1y. The latter was the common name for the standard before it was known in which year it would be released. In older versions (including yours) only the latter is accepted as the release year wasn't known yet when those versions were released.

I used "sudo apt-get install g++" which should automatically retrieve the latest version, is that correct?

It installs the latest version available in the Ubuntu repositories, not the latest version that exists.

The latest GCC version is 5.2.

The answer depends on what do you need a loop for.

of course you can have a loop similar to Java:

for i in xrange(len(my_list)):

but I never actually used loops like this,

because usually you want to iterate

for obj in my_list

or if you need an index as well

for index, obj in enumerate(my_list)

or you want to produce another collection from a list

map(some_func, my_list)

[somefunc[x] for x in my_list]

also there are itertools module that covers most of iteration related cases

also please take a look at the builtins like any, max, min, all, enumerate

I would say - do not try to write Java-like code in python. There is always a pythonic way to do it.

I'm usually facing this problem when dealing with events from an input field, like key up. But remember that the event could stem from anywhere, e.g. from a keyup listener on document, where there is no associated value. So in order to correctly provide the information I'd provide an additional type:

interface KeyboardEventOnInputField extends KeyboardEvent {
  target: HTMLInputElement;
}
...

  onKeyUp(e: KeyboardEventOnInputField) {
    const inputValue = e.target.value;
    ...
  }

If the input to the function has a type of Event, you might need to tell typescript what it actually is:

  onKeyUp(e: Event) {
    const evt = e as KeyboardEventOnInputField;
    const inputValue = evt.target.value;
    this.inputValue.next(inputValue);
  }

This is for example required in Angular.

    jQuery(function ($) {
        $('li#linkss').find('a').on('click', function (e) {
            var
                link_href = $(this).attr('href')
                , $linkElem = $(link_href)
                , $linkElem_scroll = $linkElem.get(0) && $linkElem.position().top - 115;
            $('html, body')
                .animate({
                    scrollTop: $linkElem_scroll
                }, 'slow');
            e.preventDefault();
        });
    });

If you are using npm you can use the shelljs package

To install: npm install [-g] shelljs

var shell = require('shelljs');
shell.ls('*.js').forEach(function (file) {
// do something
});

Extension to ollyc recipe :

CREATE VIEW foreign_keys_view AS
SELECT
    tc.table_name, kcu.column_name,
    ccu.table_name AS foreign_table_name,
    ccu.column_name AS foreign_column_name
FROM
    information_schema.table_constraints AS tc
    JOIN information_schema.key_column_usage 
        AS kcu ON tc.constraint_name = kcu.constraint_name
    JOIN information_schema.constraint_column_usage 
        AS ccu ON ccu.constraint_name = tc.constraint_name
WHERE constraint_type = 'FOREIGN KEY';

Then:

SELECT * FROM foreign_keys_view WHERE table_name='YourTableNameHere';

try with screen -d -r or screen -D -RR

"\n" = new line
'\n' = \n
"\t" = tab
'\t' = \t

show variables where Variable_name='hostname'; 

That could help you !!

Try this:

private void NewNumber()
  {
     Random a = new Random(Guid.newGuid().GetHashCode());
     MyNumber = a.Next(0, 10);
  }

Some Explnations:

Guid : base on here : Represents a globally unique identifier (GUID)

Guid.newGuid() produces a unique identifier like "936DA01F-9ABD-4d9d-80C7-02AF85C822A8"

and it will be unique in all over the universe base on here

Hash code here produce a unique integer from our unique identifier

so Guid.newGuid().GetHashCode() gives us a unique number and the random class will produce real random numbers throw this

Sample: https://rextester.com/ODOXS63244

generated ten random numbers with this approach with result of:

-1541116401
7
-1936409663
3
-804754459
8
1403945863

1287118327

9
-752742620
4
-175247185

1666734552
7

we got two 1s next to each other, but the hash codes do not same.

I know the question is asking about your "csv" package implementation, but for your information, there are options that are much simpler — numpy, for instance.

import numpy as np
np.savetxt('data.csv', (col1_array, col2_array, col3_array), delimiter=',')

(This answer posted 6 years later, for posterity's sake.)

In a different case similar to what you're asking about, say you have two columns like this:

names = ['Player Name', 'Foo', 'Bar']
scores = ['Score', 250, 500]

You could save it like this:

np.savetxt('scores.csv', [p for p in zip(names, scores)], delimiter=',', fmt='%s')

scores.csv would look like this:

Player Name,Score
Foo,250
Bar,500

YES, I think it is important to version your database. Not the data, but the schema for certain.

In Ruby On Rails, this is handled by the framework with "migrations". Any time you alter the db, you make a script that applies the changes and check it into source control.

My shop liked that idea so much that we added the functionality to our Java-based build using shell scripts and Ant. We integrated the process into our deployment routine. It would be fairly easy to write scripts to do the same thing in other frameworks that don't support DB versioning out-of-the-box.

Using sed

If one would like to do this systematically for all external links, CSS is no option. However, one could run the following sed command once the (X)HTML has been created from Markdown:

sed -i 's|href="http|target="_blank" href="http|g' index.html

This can be further automated in a single workflow when a Makefile with build instructions is employed.

PS: This answer was written at a time when extension link_attributes was not yet available in Pandoc.

As others already pointed out you can use SharedPreferences generally but if you would like to store data encrypted it's a bit inconvenient. Fortunately, there is an easier and quicker way to encrypt data now since there is an implementation of SharedPreferences that encrypts keys and values. You can use EncryptedSharedPreferences in Android JetPack Security.

Just add AndroidX Security into your build.gradle:

implementation 'androidx.security:security-crypto:1.0.0-rc01'

And you can use it like this:

String masterKeyAlias = MasterKeys.getOrCreate(MasterKeys.AES256_GCM_SPEC);

SharedPreferences sharedPreferences = EncryptedSharedPreferences.create(
    "secret_shared_prefs",
    masterKeyAlias,
    context,
    EncryptedSharedPreferences.PrefKeyEncryptionScheme.AES256_SIV,
    EncryptedSharedPreferences.PrefValueEncryptionScheme.AES256_GCM
);

// use the shared preferences and editor as you normally would
SharedPreferences.Editor editor = sharedPreferences.edit();

See more details: https://android-developers.googleblog.com/2020/02/data-encryption-on-android-with-jetpack.html

I got this issue while installing transformers library from HuggingFace. It was due to the fact package enum34 was installed in my environment which was overriding built-in enum in Python. This package was probably installed by something as for forward compatibility which is no longer needed with Python 3.6+. So the solution is simply,

pip uninstall -y enum34

No need to use a macro. Supposing your first string is in A1.

=RIGHT(A1, 4)

Drag this down and you will get your four last characters.

Edit: To be sure, if you ever have sequences like 'ABC DEF' and want the last four LETTERS and not CHARACTERS you might want to use trimspaces()

=RIGHT(TRIMSPACES(A1), 4)

Edit: As per brettdj's suggestion, you may want to check that your string is actually 4-character long or more:

=IF(TRIMSPACES(A1)>=4, RIGHT(TRIMSPACES(A1), 4), TRIMSPACES(A1))

Frontend refers to the client-side, whereas backend refers to the server-side of the application. Both are crucial to web development, but their roles, responsibilities and the environments they work in are totally different. Frontend is basically what users see whereas backend is how everything works

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

If this is an HTML file where you are using file://FileName then using a CDN like src="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.2.1/angular.min.js" will not work.

You will have to include the .js file in your code.

This may also be achieved using matplotlib.pyplot.quiver, as noted in the linked answer;

plt.quiver([0, 0, 0], [0, 0, 0], [1, -2, 4], [1, 2, -7], angles='xy', scale_units='xy', scale=1)
plt.xlim(-10, 10)
plt.ylim(-10, 10)
plt.show()

you can try using this

    System.Web.HttpContext.Current.Server.MapPath(path);

or use HostingEnvironment.MapPath

    System.Web.Hosting.HostingEnvironment.MapPath(path);

read.table wants to return a data.frame, which must have an element in each column. Therefore R expects each row to have the same number of elements and it doesn't fill in empty spaces by default. Try read.table("/PathTo/file.csv" , fill = TRUE ) to fill in the blanks.

e.g.

read.table( text= "Element1 Element2
Element5 Element6 Element7" , fill = TRUE , header = FALSE )
#        V1       V2       V3
#1 Element1 Element2         
#2 Element5 Element6 Element7

A note on whether or not to set header = FALSE... read.table tries to automatically determine if you have a header row thus:

header is set to TRUE if and only if the first row contains one fewer field than the number of columns

You can get the first of the month, by calculating the last_day of the month before and add one day. It is awkward, but I think it is better than formatting a date as string and use that for calculation.

select 
  *
from
  yourtable t
where
  /* Greater or equal to the start of last month */
  t.date >= DATE_ADD(LAST_DAY(DATE_SUB(NOW(), INTERVAL 2 MONTH)), INTERVAL 1 DAY) and
  /* Smaller or equal than one month ago */
  t.date <= DATE_SUB(NOW(), INTERVAL 1 MONTH)

You can do it by combining tr and wc commands. For example, to count e in the string referee

echo "referee" | tr -cd 'e' | wc -c

output

4

Explanations: Command tr -cd 'e' removes all characters other than 'e', and Command wc -c counts the remaining characters.

Multiple lines of input are also good for this solution, like command cat mytext.txt | tr -cd 'e' | wc -c can counts e in the file mytext.txt, even thought the file may contain many lines.

*** Update ***

To solve the multiple spaces in from of the number (@tom10271), simply append a piped tr command:

 tr -d ' '

For example:

echo "referee" | tr -cd 'e' | wc -c | tr -d ' '
