Generally when I want to create a JSON or YAML string, I start out by building the Perl data structure, and then running a simple conversion on it. You could put a UI in front of the Perl data structure generation, e.g. a web form.

Converting a structure to JSON is very straightforward:

use strict;
use warnings;
use JSON::Any;

my $data = { arbitrary structure in here };
my $json_handler = JSON::Any->new(utf8=>1);
my $json_string = $json_handler->objToJson($data);

If all the cases have the same length you can use
switch (mystring.SubString(0,Math.Min(len, mystring.Length))).
Another option is to have a function that will return categoryId based on the string and switch on the id.

the major difference between greedy method and dynamic programming is in greedy method only one optimal decision sequence is ever generated and in dynamic programming more than one optimal decision sequence may be generated.

you can append the file with >> sign. It insert the contents at the last of the file which we are using.e.g if file let its name is myfile contains xyz then cat >> myfile abc ctrl d

after the above process the myfile contains xyzabc.

the IP adress is 0.0.0.0, state = LISTENING: means that port 80 is listening to all interfaces (not used)

How to read NETSTAT -AN results:

Try doing it in viewDidLoad. Generally you should defer anything you can until that point anyway, when a UIViewController is inited it still might be quite a while before it displays, no point in doing work early and tying up memory.

- (void)viewDidLoad {
  [super viewDidLoad];

  UIBarButtonItem *anotherButton = [[UIBarButtonItem alloc] initWithTitle:@"Show" style:UIBarButtonItemStylePlain target:self action:@selector(refreshPropertyList:)];          
  self.navigationItem.rightBarButtonItem = anotherButton;
  // exclude the following in ARC projects...
  [anotherButton release];
}

As to why it isn't working currently, I can't say with 100% certainty without seeing more code, but a lot of stuff happens between init and the view loading, and you may be doing something that causes the navigationItem to reset in between.

Calling -sizeToFit on UILabel instance will automatically resize it to fit text it displays, no calculating required. If you need the size, you can get it from label's frame property after that.

label.numberOfLines = 0; // allows label to have as many lines as needed
label.text = @"some long text";
[label sizeToFit];
NSLog(@"Label's frame is: %@", NSStringFromCGRect(label.frame));

I created this method, it is ideal because it aborts the connection without downloading it in its entirety, ideal for checking if videos or large images exist, decreasing the response time and the need to download the entire file

// if-url-exist.js v1
function ifUrlExist(url, callback) {
    let request = new XMLHttpRequest;
    request.open('GET', url, true);
    request.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded; charset=UTF-8');
    request.setRequestHeader('Accept', '*/*');
    request.onprogress = function(event) {
        let status = event.target.status;
        let statusFirstNumber = (status).toString()[0];
        switch (statusFirstNumber) {
            case '2':
                request.abort();
                return callback(true);
            default:
                request.abort();
                return callback(false);
        };
    };
    request.send('');
};

Example of use:

ifUrlExist(url, function(exists) {
    console.log(exists);
});

Yes, it will be encrypted.

You'll understand it if you simply check what happens behind the scenes.

1. The browser or application will first break down the URL and try to get the IP of the host using a DNS Query. ie: A DNS request will be made to find the IP address of the domain (www.example.com). Please note that no other information will be sent via this request.
2. The browser or application will initiate a SSL connection with the IP address received from the DNS request. Certificates will be exchanged and this happens at the transport level. No application level information will be transferred at this point. Remember that the Basic authentication is part of HTTP and HTTP is an application level protocol. Not a transport layer task.
3. After establishing the SSL connection, now the necessary data will be passed to the server. ie: The path or the URL, the parameters and basic authentication username and password.

From the bash manpage:

When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. The --noprofile option may be used when the shell is started to inhibit this behavior.

When a login shell exits, bash reads and executes commands from the file ~/.bash_logout, if it exists.

When an interactive shell that is not a login shell is started, bash reads and executes commands from ~/.bashrc, if that file exists. This may be inhibited by using the --norc option. The --rcfile file option will force bash to read and execute commands from file instead of ~/.bashrc.

Thus, if you want to get the same behavior for both login shells and interactive non-login shells, you should put all of your commands in either .bashrc or .bash_profile, and then have the other file source the first one.

To say it differently: When you insert a key-value-pair into a HashMap where the key already exists (in a sense hashvalue() gives the same value und equal() is true, but the two objects can still differ in several ways), the key isn't replaced but the value is overwritten. The key is just used to get the hashvalue() and find the value in the table with it. Since HashSet uses the keys of a HashMap and sets arbitrary values which don't really matter (to the user) as a result the Elements of the Set aren't replaced either.

This issue was resolved thanks to this guide: https://help.ubuntu.com/community/ApacheMySQLPHP#Troubleshooting_Phpmyadmin_.26_mysql-workbench by adding

Include /etc/phpmyadmin/apache.conf

...to the /etc/apache2/apache2.conf file and restarting the service.

Delete your package-lock.json file and node_modules folder. Then do npm cache clean

npm cache clean --force

do npm install

again and run

use this method:

private ArrayList<myClass> sortList(ArrayList<myClass> list) {
    if (list != null && list.size() > 1) {
        Collections.sort(list, new Comparator<myClass>() {
            public int compare(myClass o1, myClass o2) {
                if (o1.getsortnumber() == o2.getsortnumber()) return 0;
                return o1.getsortnumber() < o2.getsortnumber() ? 1 : -1;
            }
        });
    }
    return list;
}

`

and use: mySortedlist = sortList(myList); No need to implement comparator in your class. If you want inverse order swap 1 and -1

You aren't actually sending JSON. You are passing an object as the data, but you need to stringify the object and pass the string instead.

Your dataType: "json" only tells jQuery that you want it to parse the returned JSON, it does not mean that jQuery will automatically stringify your request data.

Change to:

$.ajax({
        type: "POST",
        url: hb_base_url + "consumer",
        contentType: "application/json",
        dataType: "json",
        data: JSON.stringify({
            first_name: $("#namec").val(),
            last_name: $("#surnamec").val(),
            email: $("#emailc").val(),
            mobile: $("#numberc").val(),
            password: $("#passwordc").val()
        }),
        success: function(response) {
            console.log(response);
        },
        error: function(response) {
            console.log(response);
        }
});

I would change the SQL statement above to be more generic. Using wildcards is never a bad idea when it comes to mass population to avoid nulls.

Try this:

Update Table Set * = 0 Where * Is Null; 

The lmplot function returns a FacetGrid instance. This object has a method called set, to which you can pass key=value pairs and they will be set on each Axes object in the grid.

Secondly, you can set only one side of an Axes limit in matplotlib by passing None for the value you want to remain as the default.

Putting these together, we have:

g = sns.lmplot('X', 'Y', df, col='Z', sharex=False, sharey=False)
g.set(ylim=(0, None))

Table or record locking is available in Access during data writes. You can control the Default record locking through Tools | Options | Advanced tab:

1. No Locks
2. All Records
3. Edited Record

You can set this on a form's Record Locks or in your DAO/ADO code for specific needs.

Transactions shouldn't be a problem if you use them correctly.

Best practice: Separate your tables from All your other code. Give each user their own copy of the code file and then share the data file on a network server. Work on a 'test' copy of the code (and a link to a test data file) and then update user's individual code files separately. If you need to make data file changes (add tables, columns, etc), you will have to have all users get out of the application to make the changes.

See other answers for Oracle comparison.

"12345".each_char.map(&:to_i)

each_char does basically the same as split(''): It splits a string into an array of its characters.

hmmm, I just realize now that in the original question the string contains commas, so my answer is not really helpful ;-(..

I am not 100% sure where all of the other suggestions are trying to go, but the issue is basically related to the extension that you have on the file. If you save the file as a Excel 97/2003 workbook it will not allow you to see all million rows. Create a new sheet and save it as a workbook and you will see all million. Note: the extension will be .xlsx

Assuming having a template DataFrame, which one would like to copy with zero values filled here...

If you have no NaNs in your data set, multiplying by zero can be significantly faster:

In [19]: columns = ["col{}".format(i) for i in xrange(3000)]                                                                                       

In [20]: indices = xrange(2000)

In [21]: orig_df = pd.DataFrame(42.0, index=indices, columns=columns)

In [22]: %timeit d = pd.DataFrame(np.zeros_like(orig_df), index=orig_df.index, columns=orig_df.columns)
100 loops, best of 3: 12.6 ms per loop

In [23]: %timeit d = orig_df * 0.0
100 loops, best of 3: 7.17 ms per loop

Improvement depends on DataFrame size, but never found it slower.

And just for the heck of it:

In [24]: %timeit d = orig_df * 0.0 + 1.0
100 loops, best of 3: 13.6 ms per loop

In [25]: %timeit d = pd.eval('orig_df * 0.0 + 1.0')
100 loops, best of 3: 8.36 ms per loop

But:

In [24]: %timeit d = orig_df.copy()
10 loops, best of 3: 24 ms per loop

EDIT!!!

Assuming you have a frame using float64, this will be the fastest by a huge margin! It is also able to generate any value by replacing 0.0 to the desired fill number.

In [23]: %timeit d = pd.eval('orig_df > 1.7976931348623157e+308 + 0.0')
100 loops, best of 3: 3.68 ms per loop

Depending on taste, one can externally define nan, and do a general solution, irrespective of the particular float type:

In [39]: nan = np.nan
In [40]: %timeit d = pd.eval('orig_df > nan + 0.0')
100 loops, best of 3: 4.39 ms per loop

This is not mentioned in you post but I suspect you are initiating an SSL connection from the browser to Apache, where VirtualHosts are configured, and Apache does a revese proxy to your Tomcat.

There is a serious bug in (some versions ?) of IE that sends the 'wrong' host information in an SSL connection (see EDIT below) and confuses the Apache VirtualHosts. In short the server name presented is the one of the reverse DNS resolution of the IP, not the one in the URL.

The workaround is to have one IP address per SSL virtual hosts/server name. Is short, you must end up with something like

1 server name == 1 IP address == 1 certificate == 1 Apache Virtual Host

EDIT

Though the conclusion is correct, the identification of the problem is better described here http://en.wikipedia.org/wiki/Server_Name_Indication

I use the VFS API from Apache Commons, here is an example of how to monitor a file without much impact in performance:

DefaultFileMonitor

Here is the example:

SQL> set define off;
SQL> select * from dual where dummy='&var';

no rows selected

SQL> set define on
SQL> /
Enter value for var: X
old   1: select * from dual where dummy='&var'
new   1: select * from dual where dummy='X'

D
-
X

With set define off, it took a row with &var value, prompted a user to enter a value for it and replaced &var with the entered value (in this case, X).

You can use DataTable.Select:

var strExpr = "CostumerID = 1 AND OrderCount > 2";
var strSort = "OrderCount DESC";

// Use the Select method to find all rows matching the filter.
foundRows = ds.Table[0].Select(strExpr, strSort);  

Or you can use DataView:

ds.Tables[0].DefaultView.RowFilter = strExpr;  

UPDATE I'm not sure why you want to have a DataSet returned. But I'd go with the following solution:

var dv = ds.Tables[0].DefaultView;
dv.RowFilter = strExpr;
var newDS = new DataSet();
var newDT = dv.ToTable();
newDS.Tables.Add(newDT);

In Bash:

if [[ ( $g == 1 && $c == 123 ) || ( $g == 2 && $c == 456 ) ]]

make you service like this in your Mainifest

 <service
            android:name=".sys.service.youservice"
            android:exported="true"
        android:process=":ServiceProcess" />

then your service will run on other process named ServiceProcess

if you want make your service never die :

1. onStartCommand() return START_STICKY

2. onDestroy() -> startself

3. create a Deamon service

4. jin -> create a Native Deamon process, you can find some open-source projects on github

5. startForeground() , there is a way to startForeground without Notification ,google it

You should be able to adjust the width using the .modal-dialog class selector (in conjunction with media queries or whatever strategy you're using for responsive design):

.modal-dialog {
    width: 400px;
}

Of course.

Declaring a class abstract only means that you don't allow it to be instantiated on its own.

Declaring a method abstract means that subclasses have to provide an implementation for that method.

The two are separate concepts, though obviously you can't have an abstract method in a non-abstract class. You can even have abstract classes with final methods but never the other way around.

simply add a border: 2px solid #e60000; to your 2nd div tag CSS.

Definitely it works

#Div2Id {
    border: 2px solid #e60000; --> color is your preference
}

I ran into this after calling UIImagePickerController presentViewController: from the callback to a UIAlertView delegate. I solved the issue by pushing the presentViewController: call off the current execution trace using dispatch_async.

- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
{
    dispatch_async(dispatch_get_main_queue(), ^{
        UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
        imagePickerController.delegate = self;

        if (buttonIndex == 1)
            imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        else
            imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;

        [self presentViewController: imagePickerController
                           animated: YES
                         completion: nil];
    });
}

If you want to delete database programatically you can use deleteDatabase from Context class:

deleteDatabase(String name)
Delete an existing private SQLiteDatabase associated with this Context's application package.

Sorry its late, but I guess it would be of help to those who land here finding a solution to similar problem. The set clause should come right after the update clause. So rearranging your query with a bit change does the work.

UPDATE DHE.dbo.tblAccounts 
SET DHE.dbo.tblAccounts.ControllingSalesRep
    = DHE_Import.dbo.tblSalesRepsAccountsLink.SalesRepCode
from DHE.dbo.tblAccounts 
INNER JOIN DHE_Import.dbo.tblSalesRepsAccountsLink 
    ON DHE.dbo.tblAccounts.AccountCode
        = DHE_Import.tblSalesRepsAccountsLink.AccountCode 

You will have to set environmental variables properly for each compiler. There are commands on your Program menu for each compiler that does that, while opening a command prompt.

Another option is of course to use the IDE for building your application.

You can compile Kotlin to bytecode, then use a Java disassembler.

The decompiling may be done inside IntelliJ Idea, or using FernFlower https://github.com/fesh0r/fernflower (thanks @Jire)

There was no automated tool as I checked a couple months ago (and no plans for one AFAIK)

You might have done something like this:

>>> tuple = 45, 34  # You used `tuple` as a variable here
>>> tuple
(45, 34)
>>> l = [4, 5, 6]
>>> tuple(l)   # Will try to invoke the variable `tuple` rather than tuple type.

Traceback (most recent call last):
  File "<pyshell#10>", line 1, in <module>
    tuple(l)
TypeError: 'tuple' object is not callable
>>>
>>> del tuple  # You can delete the object tuple created earlier to make it work
>>> tuple(l)
(4, 5, 6)

Here's the problem... Since you have used a tuple variable to hold a tuple (45, 34) earlier... So, now tuple is an object of type tuple now...

It is no more a type and hence, it is no more Callable.

Never use any built-in types as your variable name... You do have any other name to use. Use any arbitrary name for your variable instead...

To get the value of my drop down box on page load, I use

document.addEventListener('DOMContentLoaded',fnName);

Hope this helps some one.

The answers you got assumed static text to compare against. If you want to compare against another column (say, you're joining two tables, and want to find ones where a column from one table is part of a column from another table), you can do this

WHERE NOT (someColumn LIKE '%' || someOtherColumn || '%')

my simple JavaScript library called FuncJS has a function called "strip_tags()" which does the task for you — without requiring you to enter any regular expressions.

For example, say that you want to remove tags from a sentence - with this function, you can do it simply like this:

strip_tags("This string <em>contains</em> <strong>a lot</strong> of tags!");

This will produce "This string contains a lot of tags!".

For a better understanding, please do read the documentation at GitHub FuncJS.

Additionally, if you'd like, please provide some feedback through the form. It would be very helpful to me!

You can use the return statement inside a stored procedure to return an integer status code (and only of integer type). By convention a return value of zero is used for success.

If no return is explicitly set, then the stored procedure returns zero.

   CREATE PROCEDURE GetImmediateManager
      @employeeID INT,
      @managerID INT OUTPUT
   AS
   BEGIN
     SELECT @managerID = ManagerID 
     FROM HumanResources.Employee 
     WHERE EmployeeID = @employeeID

     if @@rowcount = 0 -- manager not found?
       return 1;
   END

And you call it this way:

DECLARE @return_status int;
DECLARE @managerID int;

EXEC @return_status = GetImmediateManager 2, @managerID output;
if @return_status = 1
  print N'Immediate manager not found!';
else 
  print N'ManagerID is ' + @managerID;
go

You should use the return value for status codes only. To return data, you should use output parameters.

If you want to return a dataset, then use an output parameter of type cursor.

more on RETURN statement

This should work

 <a href="#" onclick="function hi(){alert('Hi!')};hi()">click</a>

You may inline any javascript inside the onclick as if you were assigning the method through javascript. I think is just a matter of making code cleaner keeping your js inside a script block

You have to first escape the backslash because it's a literal (yielding \\), and then escape it again because of the regular expression (yielding \\\\). So, Try:

 s.replaceAll("'", "\\\\'");

output:

You\'ll be totally awesome, I\'m really terrible

A simple formula to use is

=COUNTIF($B:$B,A1)

Formula specified is for cell A1. Simply copy and paste special - format to the whole of column A

ElektroStudios answer is a bit misleading.

"when you launch a bat file the working dir is the dir where it was launched" This is true if the user clicks on the batch file in the explorer.

However, if the script is called from another script using the CALL command, the current working directory does not change.

Thus, inside your script, it is better to use %~dp0subfolder\file1.txt

Please also note that %~dp0 will end with a backslash when the current script is not in the current working directory. Thus, if you need the directory name without a trailing backslash, you could use something like

call :GET_THIS_DIR
echo I am here: %THIS_DIR%
goto :EOF

:GET_THIS_DIR
pushd %~dp0
set THIS_DIR=%CD%
popd
goto :EOF

If you're only getting these to manually pass into df.set_index(), that's unnecessary. Just directly do df.set_index['your_col_name', drop=False], already.

It's very rare in pandas that you need to get an index as a Python list (unless you're doing something pretty funky, or else passing them back to NumPy), so if you're doing this a lot, it's a code smell that you're doing something wrong.

Maybe this can help you

Use filter (short version without doing a function with lambda, using __le__):

j2 = filter((5).__le__, j)

Example (python 3):

>>> j=[4,5,6,7,1,3,7,5]
>>> j2 = filter((5).__le__, j)
>>> j2
<filter object at 0x000000955D16DC18>
>>> list(j2)
[5, 6, 7, 7, 5]
>>> 

Example (python 2):

>>> j=[4,5,6,7,1,3,7,5]
>>> j2 = filter((5).__le__, j)
>>> j2
[5, 6, 7, 7, 5]
>>>

Use __le__ i recommend this, it's very easy, __le__ is your friend

If want to sort it to desired output (both versions):

>>> j=[4,5,6,7,1,3,7,5]
>>> j2 = filter((5).__le__, j)
>>> sorted(j2)
[5, 5, 6, 7, 7]
>>> 

Use sorted

I'd just drop the database and then re-create it. On a UNIX or Linux system, that should do it:

$ dropdb development_db_name
$ createdb developmnent_db_name

That's how I do it, actually.

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...

Set the Delegate of the UITextField to your ViewController, add a referencing outlet between the File's Owner and the UITextField, then implement this method:

-(BOOL)textFieldShouldReturn:(UITextField *)textField 
{
   if (textField == yourTextField) 
   {
      [textField resignFirstResponder]; 
   }
   return NO;
}

Response.write() don't give formatted output. The latter one allows you to write formatted output.

Response.write - it writes the text stream Response.output.write - it writes the HTTP Output Stream.

Another simple solution using Regex You should need to use this

using System.Text.RegularExpressions;

and the code is

string var = "Hello3453232wor705Ld";
string mystr = Regex.Replace(var, @"\d", "");
string mynumber = Regex.Replace(var, @"\D", "");
Console.WriteLine(mystr);

document.referrer serves your purpose, but it doesn't work for Internet Explorer versions earlier than IE9.

It will work for other popular browsers, like Chrome, Mozilla, Opera, Safari etc.

Generates query to update each table and column of each table.

I have used this to some of my projects before and was able to solved most of my COLLATION problems. (especially on JOINS XD) Hope some of you find it useful.

To use, just export results to delimited text (probably new line '\n')

-- EACH TABLE
SELECT CONCAT('ALTER TABLE ', TABLE_NAME,' CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;') AS 'USE DATABASE_NAME;' FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = 'DATABASE_NAME' AND TABLE_TYPE LIKE 'BASE TABLE'

-- EACH COLUMN
SELECT CONCAT('ALTER TABLE ', TABLE_NAME,' MODIFY COLUMN ', COLUMN_NAME,' ', DATA_TYPE, IF(CHARACTER_MAXIMUM_LENGTH IS NULL OR DATA_TYPE LIKE 'longtext', '', CONCAT('(',CHARACTER_MAXIMUM_LENGTH,')')),' COLLATE utf8mb4_unicode_ci;') AS 'USE DATABASE_NAME;' FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA = 'DATABASE_NAME' AND (SELECT INFORMATION_SCHEMA.TABLES.TABLE_TYPE FROM INFORMATION_SCHEMA.TABLES WHERE INFORMATION_SCHEMA.TABLES.TABLE_SCHEMA = INFORMATION_SCHEMA.COLUMNS.TABLE_SCHEMA AND INFORMATION_SCHEMA.TABLES.TABLE_NAME = INFORMATION_SCHEMA.COLUMNS.TABLE_NAME LIMIT 1) LIKE 'BASE TABLE' AND DATA_TYPE IN ('char','varchar') /* include other types if necessary */

For me it was trigger issue. By default it should On a Schedule in trigger tab. I had selected At log on and then I was waiting to run task. As it's name says at log on, means you have to logout and log on.

Try putting it on a Schedule and fire it every minute.

I want to mention something that caught me first when I was trying to adapt a SpriteKit-based app to avoid the round edges and "notch" of the new iPhone X, as suggested by the latest Human Interface Guidelines: The new property safeAreaLayoutGuide of UIView needs to be queried after the view has been added to the hierarchy (for example, on -viewDidAppear:) in order to report a meaningful layout frame (otherwise, it just returns the full screen size).

From the property's documentation:

The layout guide representing the portion of your view that is unobscured by bars and other content. When the view is visible onscreen, this guide reflects the portion of the view that is not covered by navigation bars, tab bars, toolbars, and other ancestor views. (In tvOS, the safe area reflects the area not covered the screen's bezel.) If the view is not currently installed in a view hierarchy, or is not yet visible onscreen, the layout guide edges are equal to the edges of the view.

(emphasis mine)

If you read it as early as -viewDidLoad:, the layoutFrame of the guide will be {{0, 0}, {375, 812}} instead of the expected {{0, 44}, {375, 734}}

Try this

> dt.columns.Add("ColumnName", typeof(Give the type you want));
> dt.Rows[give the row no like  or  or any no]["Column name in which you want to add data"] = Value;

 <asp:TextBox runat="server" ID="txtPassword" placeholder="Password">

This will work you might some time feel that it is not working due to Intellisence not showing placeholder

Try if this works:

Panel2.Style.Add("display", "none");

Outside of your loop create an int:

int numberOfItemIds = 0;
for (int i = 0; i < key.length; i++) {

Then in the loop, increment it:

itemId = p.getItemId();
numberOfItemIds++;

It seems to me like you could just check for !stream.paused.

You can redirect in jQuery like this:

$(location).attr('href', 'http://yourPage.com/');

In Java all the variables you declare are actually "references" to the objects (or primitives) and not the objects themselves.

When you attempt to execute one object method, the reference asks the living object to execute that method. But if the reference is referencing NULL (nothing, zero, void, nada) then there is no way the method gets executed. Then the runtime let you know this by throwing a NullPointerException.

Your reference is "pointing" to null, thus "Null -> Pointer".

The object lives in the VM memory space and the only way to access it is using this references. Take this example:

public class Some {
    private int id;
    public int getId(){
        return this.id;
    }
    public setId( int newId ) {
        this.id = newId;
    }
}

And on another place in your code:

Some reference = new Some();    // Point to a new object of type Some()
Some otherReference = null;     // Initiallly this points to NULL

reference.setId( 1 );           // Execute setId method, now private var id is 1

System.out.println( reference.getId() ); // Prints 1 to the console

otherReference = reference      // Now they both point to the only object.

reference = null;               // "reference" now point to null.

// But "otherReference" still point to the "real" object so this print 1 too...
System.out.println( otherReference.getId() );

// Guess what will happen
System.out.println( reference.getId() ); // :S Throws NullPointerException because "reference" is pointing to NULL remember...

This an important thing to know - when there are no more references to an object (in the example above when reference and otherReference both point to null) then the object is "unreachable". There is no way we can work with it, so this object is ready to be garbage collected, and at some point, the VM will free the memory used by this object and will allocate another.

Both classes Rectangle and Ellipse need to override both of the abstract methods.

To work around this, you have 3 options:

• Add the two methods
• Make each class that extends Shape abstract

• Have a single method that does the function of the classes that will extend Shape, and override that method in Rectangle and Ellipse, for example:

  abstract class Shape {
      // ...
      void draw(Graphics g);
  }
  

And

    class Rectangle extends Shape {
        void draw(Graphics g) {
            // ...
        }
    }

Finally

    class Ellipse extends Shape {
        void draw(Graphics g) {
            // ...
        }
    }

And you can switch in between them, like so:

    Shape shape = new Ellipse();
    shape.draw(/* ... */);

    shape = new Rectangle();
    shape.draw(/* ... */);

Again, just an example.

There is now a HDF5 based clone of pickle called hickle!

https://github.com/telegraphic/hickle

import hickle as hkl 

data = { 'name' : 'test', 'data_arr' : [1, 2, 3, 4] }

# Dump data to file
hkl.dump( data, 'new_data_file.hkl' )

# Load data from file
data2 = hkl.load( 'new_data_file.hkl' )

print( data == data2 )

EDIT:

There also is the possibility to "pickle" directly into a compressed archive by doing:

import pickle, gzip, lzma, bz2

pickle.dump( data, gzip.open( 'data.pkl.gz',   'wb' ) )
pickle.dump( data, lzma.open( 'data.pkl.lzma', 'wb' ) )
pickle.dump( data,  bz2.open( 'data.pkl.bz2',  'wb' ) )

As this is specifically tagged for jQuery -

$("#myElement")[0].getBoundingClientRect();

or

$("#myElement").get(0).getBoundingClientRect();

(These are functionally identical, in some older browsers .get() was slightly faster)

Note that if you try to get the values via jQuery calls then it will not take into account any css transform values, which can give unexpected results...

Note 2: In jQuery 3.0 it has changed to using the proper getBoundingClientRect() calls for its own dimension calls (see the jQuery Core 3.0 Upgrade Guide) - which means that the other jQuery answers will finally always be correct - but only when using the new jQuery version - hence why it's called a breaking change...

Google play finds you as developer via your keystore.

and maybe your country IP is banned on Google when you generate your new keystore.

change your IP Address and generate new keystore, the problem will be fixed.

if you didn't succeed, use another Gmail in Android Studio and generate new keystore.

You need to add:

#include <string>

In your header file.

before starting your actions, use

 sleep(5);

Another Alternative for those who are probing around and/or in interactive mode:

$Error[0].Exception.LoaderExceptions

From the documentation of the HttpWebRequest.Timeout property:

A Domain Name System (DNS) query may take up to 15 seconds to return or time out. If your request contains a host name that requires resolution and you set Timeout to a value less than 15 seconds, it may take 15 seconds or more before a WebException is thrown to indicate a timeout on your request.

Is it possible that your DNS query is the cause of the timeout?

Use getpass for this purpose.

Two years old, but for completeness...

Standard, inline approach: (i.e. behaviour you'd get when using & in Linux)

START /B CMD /C CALL "foo.bat" [args [...]]

Notes: 1. CALL is paired with the .bat file because that where it usually goes.. (i.e. This is just an extension to the CMD /C CALL "foo.bat" form to make it asynchronous. Usually, it's required to correctly get exit codes, but that's a non-issue here.); 2. Double quotes around the .bat file is only needed if the name contains spaces. (The name could be a path in which case there's more likelihood of that.).

If you don't want the output:

START /B CMD /C CALL "foo.bat" [args [...]] >NUL 2>&1

If you want the bat to be run on an independent console: (i.e. another window)

START CMD /C CALL "foo.bat" [args [...]]

If you want the other window to hang around afterwards:

START CMD /K CALL "foo.bat" [args [...]]

Note: This is actually poor form unless you have users that specifically want to use the opened window as a normal console. If you just want the window to stick around in order to see the output, it's better off putting a PAUSE at the end of the bat file. Or even yet, add ^& PAUSE after the command line:

START CMD /C CALL "foo.bat" [args [...]] ^& PAUSE

You should hook onto the change event of the <select> element instead of on the individual options.

var select = document.getElementById('test'),
onChange = function(event) {
    var shown = this.options[this.selectedIndex].value == 1;

    document.getElementById('hidden_div').style.display = shown ? 'block' : 'none';
};

// attach event handler
if (window.addEventListener) {
    select.addEventListener('change', onChange, false);
} else {
    // of course, IE < 9 needs special treatment
    select.attachEvent('onchange', function() {
        onChange.apply(select, arguments);
    });
}

Demo

What solved my issue was creating a file startmongo.conf that sets the bind_ip to 127.0.0.1 . After that, I just created a *.bat to start the mongo using something like:

mongod --config c:\mongodb\bin\startmongo.conf

.shadow {
    -moz-box-shadow:    3px 3px 5px 6px #ccc;
    -webkit-box-shadow: 3px 3px 5px 6px #ccc;
    box-shadow:         3px 3px 5px 6px #ccc;
}

Download Spring STS (SpringSource Tool Suite) and choose Spring Template Project from the Dashboard. This is the easiest way to get a preconfigured spring mvc project, ready to go.

This is the solution I came up with if anyone is interested.

https://kellyschronicles.wordpress.com/2017/12/16/dynamic-predicate-for-a-linq-query/

First we identify the single element type we need to use ( Of TRow As DataRow) and then identify the “source” we are using and tie the identifier to that source ((source As TypedTableBase(Of TRow)). Then we must specify the predicate, or the WHERE clause that is going to be passed (predicate As Func(Of TRow, Boolean)) which will either be returned as true or false. Then we identify how we want the returned information ordered (OrderByField As String). Our function will then return a EnumerableRowCollection(Of TRow), our collection of datarows that have met the conditions of our predicate(EnumerableRowCollection(Of TRow)). This is a basic example. Of course you must make sure your order field doesn’t contain nulls, or have handled that situation properly and make sure your column names (if you are using a strongly typed datasource never mind this, it will rename the columns for you) are standard.

To display dialog box, you can use the following code. This is to display a simple AlertDialog box with multiple check boxes:

AlertDialog.Builder alertDialog= new AlertDialog.Builder(MainActivity.this); .
            alertDialog.setTitle("this is a dialog box ");
            alertDialog.setPositiveButton("ok", new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    // TODO Auto-generated method stub
                    Toast.makeText(getBaseContext(),"ok ive wrote this 'ok' here" ,Toast.LENGTH_SHORT).show();

                }
            });
            alertDialog.setNegativeButton("cancel", new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    // TODO Auto-generated method stub
                        Toast.makeText(getBaseContext(), "cancel ' comment same as ok'", Toast.LENGTH_SHORT).show();


                }
            });
            alertDialog.setMultiChoiceItems(items, checkedItems, new DialogInterface.OnMultiChoiceClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which, boolean isChecked) {
                    // TODO Auto-generated method stub
                    Toast.makeText(getBaseContext(), items[which] +(isChecked?"clicked'again i've wrrten this click'":"unchecked"),Toast.LENGTH_SHORT).show();

                }
            });
            alertDialog.show();

Heading

Whereas if you are using the showDialog function to display different dialog box or anything as per the arguments passed, you can create a self function and can call it under the onClickListener() function. Something like:

 public CharSequence[] items={"google","Apple","Kaye"};
public boolean[] checkedItems=new boolean[items.length];
Button bt;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    bt=(Button) findViewById(R.id.bt);
    bt.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            display(0);             
        }       
    });
}

and add the code of dialog box given above in the function definition.

This works for my Debian:

$ /usr/sbin/apache2 -v

If you are using ubutu and you have the path like this /opt/lampp then type the following command in terminal.

Okay adding to @null's awesome post about using the Asset Catalog.

You may need to do the following to get the App's Icon linked and working for Ad-Hoc distributions / production to be seen in Organiser, Test flight and possibly unknown AppStore locations.

After creating the Asset Catalog, take note of the name of the Launch Images and App Icon names listed in the .xassets in Xcode.

By Default this should be

• AppIcon
• LaunchImage

[To see this click on your .xassets folder/icon in Xcode.] (this can be changed, so just take note of this variable for later)

What is created now each build is the following data structures in your .app:

For App Icons:

iPhone

• AppIcon57x57.png (iPhone non retina) [Notice the Icon name prefix]
• [email protected] (iPhone retina)

And the same format for each of the other icon resolutions.

iPad

• AppIcon72x72~ipad.png (iPad non retina)
• AppIcon72x72@2x~ipad.png (iPad retina)

(For iPad it is slightly different postfix)

Main Problem

Now I noticed that in my Info.plist in Xcode 5.0.1 it automatically attempted and failed to create a key for "Icon files (iOS 5)" after completing the creation of the Asset Catalog.

If it did create a reference successfully / this may have been patched by Apple or just worked, then all you have to do is review the image names to validate the format listed above.

Final Solution:

Add the following key to you main .plist

I suggest you open your main .plist with a external text editor such as TextWrangler rather than in Xcode to copy and paste the following key in.

<key>CFBundleIcons</key>
<dict>
    <key>CFBundlePrimaryIcon</key>
    <dict>
        <key>CFBundleIconFiles</key>
        <array>
            <string>AppIcon57x57.png</string>
            <string>[email protected]</string>
            <string>AppIcon72x72~ipad.png</string>
            <string>AppIcon72x72@2x~ipad.png</string>
        </array>
    </dict>
</dict>

Please Note I have only included my example resolutions, you will need to add them all.

If you want to add this Key in Xcode without an external editor, Use the following:

• Icon files (iOS 5) - Dictionary
• Primary Icon - Dictionary
• Icon files - Array
• Item 0 - String = AppIcon57x57.png And for each other item / app icon.

Now when you finally archive your project the final .xcarchive payload .plist will now include the above stated icon locations to build and use.

Do not add the following to any .plist: Just an example of what Xcode will now generate for your final payload

<key>IconPaths</key>
<array>
    <string>Applications/Example.app/AppIcon57x57.png</string>
    <string>Applications/Example.app/[email protected]</string>
    <string>Applications/Example.app/AppIcon72x72~ipad.png</string>
    <string>Applications/Example.app/AppIcon72x72@2x~ipad.png</string>
</array>

I've recently done it slightly different to some of the examples above so thought I'd share, albeit very late!

Firstly the HTML, note there is only one class within the header:

<body>

<header class="GreyHeader">
</header>


</body>

And the CSS:

body {
height: 3000px;
}

.GreyHeader{
height: 200px; 
background-color: rgba(107,107,107,0.66);
position: fixed;
top:200;
width: 100%;

}

.FireBrickRed {
height: 100px;
background-color: #b22222;
position: fixed;
top:200;
width: 100%;
}

.transition {
  -webkit-transition: height 2s; /* For Safari 3.1 to 6.0 */
  transition: height 2s;
}

The html uses only the class .greyHeader but within the CSS I have created another class to call once the scroll has reached a certain point from the top:

$(function() {
    var header = $(".GreyHeader");
    $(window).scroll(function() {    
        var scroll = $(window).scrollTop();

        if (scroll >= 500) {
            header.removeClass('GreyHeader').addClass("FireBrickRed ");
            header.addClass("transition");
        } else {
            header.removeClass("FireBrickRed ").addClass('GreyHeader');
            header.addClass("transition");
        }
    });
});

I'm using !important to change the style of an element on a SharePoint web part. The JavaScript code that builds the elements on the web part is buried many levels deep in the SharePoint inner-workings.

Attempting to find where the style is applied, and then attempting to modify it seems like a lot of wasted effort to me. Using the !important tag in a custom CSS file is much, much easier.

Depending on your project, you might want to consider using EditorConfig (https://editorconfig.org/). There's a Notepad++ plugin which will load an .editorconfig where you can specify "lf" as the mandatory line ending.

I've only started using it, but it's nice so far, and open source projects I've worked on have included .editorconfig files for years. The "EOL Conversion" setting isn't changed, so it can be a bit confusing, but if you "View > Show Symbol > Show End of Line", you can see that it's adding LF instead of CRLF, even when "EOL Conversion" and the lower bottom corner shows something else (e.g. Windows (CR LF)).

To Access the element you need to get an iterator . But Iterator does not guarantee in a particular order unless it is some Exceptional case. so it is not sure to get the first Element.

You can wrap all tasks which can fail in block, and use ignore_errors: yes with that block.

tasks:
  - name: ls
    command: ls -la
  - name: pwd
    command: pwd

  - block:
    - name: ls non-existing txt file
      command: ls -la no_file.txt
    - name: ls non-existing pic
      command: ls -la no_pic.jpg
    ignore_errors: yes 

Read more about error handling in blocks here.

I believe what he was looking for was mime code carrier return type code such as %0D%0A (for a Return or line break) and \u00A0 (for spacing) or alternatively $#032

The easiest way is:

File.WriteAllText(path, string.Empty)

However, I recommend you use FileStream because the first solution can throw UnauthorizedAccessException

using(FileStream fs = File.Open(path,FileMode.OpenOrCreate, FileAccess.ReadWrite))
{
     lock(fs)
     {
          fs.SetLength(0);
     }
}

You cannot add a column with a default value in Hive. You have the right syntax for adding the column ALTER TABLE test1 ADD COLUMNS (access_count1 int);, you just need to get rid of default sum(max_count). No changes to that files backing your table will happen as a result of adding the column. Hive handles the "missing" data by interpreting NULL as the value for every cell in that column.

So now your have the problem of needing to populate the column. Unfortunately in Hive you essentially need to rewrite the whole table, this time with the column populated. It may be easier to rerun your original query with the new column. Or you could add the column to the table you have now, then select all of its columns plus value for the new column.

You also have the option to always COALESCE the column to your desired default and leave it NULL for now. This option fails when you want NULL to have a meaning distinct from your desired default. It also requires you to depend on always remembering to COALESCE.

If you are very confident in your abilities to deal with the files backing Hive, you could also directly alter them to add your default. In general I would recommend against this because most of the time it will be slower and more dangerous. There might be some case where it makes sense though, so I've included this option for completeness.

If you are using Developer Edition of SQL Server change ".\SQLEXPRESS" to your computer name in connection string.

Before:

Data Source=.\SQLEXPRESS;Initial Catalog=SchoolDB-EF6CodeFirst;Integrated Security=True;MultipleActiveResultSets=True

After:

        assert(x1 < x2);
        assert(y1 < y2);
    }

    int x1, x2, y1, y2;
};

    bool noOverlap = r1.x1 > r2.x2 ||
                     r2.x1 > r1.x2 ||

This refers to the object you’re “in” right now. In other words,this refers to the receiving object. You use this to clarify which variable you’re referring to.Java_whitepaper page :37

class Point extends Object
{
    public double x;
    public double y;

    Point()
    {
        x = 0.0;
        y = 0.0;
    }

    Point(double x, double y)
    {
        this.x = x;
        this.y = y;
    }
}

In the above example code this.x/this.y refers to current class that is Point class x and y variables where (double x,double y) are double values passed from different class to assign values to current class .

There are also many other media types based around XML, for example application/rss+xml or image/svg+xml. It's a safe bet that any unrecognised but registered ending in +xml is XML-based. See the IANA list for registered media types ending in +xml.

Usually, we want to divide our vector into a number of intervals. In this case, you can use a function where (a) is a vector and (b) is the number of intervals. (Let's suppose you want 4 intervals)

a <- 1:10
b <- 4

FunctionIntervalM <- function(a,b) {
  seq(from=min(a), to = max(a), by = (max(a)-min(a))/b)
}

FunctionIntervalM(a,b)
# 1.00  3.25  5.50  7.75 10.00

Therefore you have 4 intervals:

1.00 - 3.25 
3.25 - 5.50
5.50 - 7.75
7.75 - 10.00

You can also use a cut function

  cut(a, 4)

# (0.991,3.25] (0.991,3.25] (0.991,3.25] (3.25,5.5]   (3.25,5.5]   (5.5,7.75]  
# (5.5,7.75]   (7.75,10]    (7.75,10]    (7.75,10]   
#Levels: (0.991,3.25] (3.25,5.5] (5.5,7.75] (7.75,10]

The issue here is your version of AngularJS; ng-attr is not working due to the fact that it was introduced in version 1.1.4. I am unsure as to why title="{{product.shortDesc}}" isn't working for you, but I imagine it is for similar reasons (old Angular version). I tested this on 1.2.9 and it is working for me.

As for the other answers here, this is NOT among the few use cases for ng-attr! This is a simple double-curly-bracket situation:

<a title="{{product.shortDesc}}" ng-bind="product.shortDesc" />

This method worked in my case.

video=getElementsByTagName('video');
function removeControls(video){
  video.removeAttribute('controls');
}
window.onload=removeControls(video);

%* seems to hold all of the arguments passed to the script.

= is a padding character. If the input stream has length that is not a multiple of 3, the padding character will be added. This is required by decoder: if no padding present, the last byte would have an incorrect number of zero bits.

Better and deeper explanation here: https://base64tool.com/detect-whether-provided-string-is-base64-or-not/

As other have mentioned, you will probably end up using a vector of pointers instead.

However, you may want to consider using a ptr_vector instead!

You can use HTML5 autofocus for this. You don't need jQuery or other JavaScript.

<input type="text" name="some_field" autofocus>

Note this will not work on IE9 and lower.

Or when you deal with text in Python if it is a Unicode text, make a note it is Unicode.

Set text=u'unicode text' instead just text='unicode text'.

This worked in my case.

I usually use the -p flag with a git checkout from the other branch which I find easier and more granular than most other methods I have come across.

In principle:

git checkout <other_branch_name> <files/to/grab in/list/separated/by/spaces> -p

example:

git checkout mybranch config/important.yml app/models/important.rb -p

You then get a dialog asking you which changes you want in "blobs" this pretty much works out to every chunk of continuous code change which you can then signal y (Yes) n (No) etc for each chunk of code.

The -p or patch option works for a variety of commands in git including git stash save -p which allows you to choose what you want to stash from your current work

I sometimes use this technique when I have done a lot of work and would like to separate it out and commit in more topic based commits using git add -p and choosing what I want for each commit :)

Setattr: We use setattr to add an attribute to our class instance. We pass the class instance, the attribute name, and the value. and with getattr we retrive these values

For example

Employee = type("Employee", (object,), dict())

employee = Employee()

# Set salary to 1000
setattr(employee,"salary", 1000 )

# Get the Salary
value = getattr(employee, "salary")

print(value)

Just to add to the responses above. I had this same issue when i first started using ASP.Net MVC and i was doing a Response.Redirect during a controller action:

Response.Redirect("/blah", true);

Instead of returning a Response.Redirect action i should have been returning a RedirectAction:

return Redirect("/blah");

You ignore case when you treat the data, not when you retrieve/store it. If you want to store everything in lowercase use String#toLowerCase, in uppercase use String#toUpperCase.

Then when you have to actually treat it, you may use out of the bow methods, like String#equalsIgnoreCase(java.lang.String). If nothing exists in the Java API that fulfill your needs, then you'll have to write your own logic.

Try This

$nextyear  = date("M d,Y",mktime(0, 0, 0, date("m",strtotime($startDate)),   date("d",strtotime($startDate)),   date("Y",strtotime($startDate))+1));

If you want your div to keep it's circular shape even if you change its width/height (using js for instance) set the radius to 50%. Example: css:

.circle {
    border-radius: 50%/50%; 
    width: 50px;
    height: 50px;
    background: black;
}

html:

<div class="circle"></div>

Found in the JUnit API:

/**
 * ...as the moon sets over the early morning Merlin, Oregon
 * mountains, our intrepid adventurers type...
 */
public Test createTest(Class theClass, String name) {
    ...
}

For python datasets you can use an index.

tmpColumnsSQL = ("show columns in dim.date_dim")
hiveCursor.execute(tmpColumnsSQL)
columnlist = hiveCursor.fetchall()

for columns in jayscolumnlist:
    print columns[0]

for i in range(len(jayscolumnlist)):    
    print columns[i][0])

There's also Array.find() in ES6 which returns the first matching element it finds.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/find

const myArray = [1, 2, 3]

const myElement = myArray.find((element) => element === 2)

console.log(myElement)
// => 2

Array.Equals() appears to only test for the same instance.

There doesn't appear to be a method that compares the values but it would be very easy to write.

Just compare the lengths, if not equal, return false. Otherwise, loop through each value in the array and determine if they match.

Using straight Linq, with the Distinct() extension:

var idList = (from x in yourList select x.ID).Distinct();

List user's procedures and functions for all databases:

SELECT 
    `ROUTINE_SCHEMA` AS `database`
    ,`ROUTINE_TYPE` AS `type`
    ,`SPECIFIC_NAME` AS `name`
    ,`DTD_IDENTIFIER` AS `data_type`
FROM 
    `INFORMATION_SCHEMA`.`ROUTINES`
WHERE
  `definer` LIKE
  CONCAT('%', CONCAT((SUBSTRING_INDEX((SELECT user()), '@', 1)), '%'))
ORDER BY
    `database`
    ,`type`
    ,`name`
;

List user's procedures and functions for the database in use:

SELECT 
    `ROUTINE_SCHEMA` AS `database`
    ,`ROUTINE_TYPE` AS `type`
    ,`SPECIFIC_NAME` AS `name`
    ,`DTD_IDENTIFIER` AS `data_type`
FROM 
    `INFORMATION_SCHEMA`.`ROUTINES`
WHERE
  `definer` LIKE
  CONCAT('%', CONCAT((SUBSTRING_INDEX((SELECT user()), '@', 1)), '%'))
AND
   `ROUTINE_SCHEMA` = DATABASE()
ORDER BY
    `type`
    ,`name`
;

You get the value of the textarea, use it :

$('.type').keyup(function() {
    var v = $('.type').val(); // you'd better use this.value here
    if (v.indexOf('> <')!=-1) {
       console.log('contains > <');        
    }
});

public static FileDetail getFileDetailFromUri(final Context context, final Uri uri) {
    FileDetail fileDetail = null;
    if (uri != null) {
        fileDetail = new FileDetail();
        // File Scheme.
        if (ContentResolver.SCHEME_FILE.equals(uri.getScheme())) {
            File file = new File(uri.getPath());
            fileDetail.fileName = file.getName();

I had the same problem. I resolved, uninstalling all de the versions in my pc and then reinstall dotnet.

You can make use of java.util.Date with direct date string format:

String timeStamp = new SimpleDateFormat("yyyy.MM.dd.HH.mm.ss").format(new Date());

Based on the answer from @savindra , if you RHM on your application and try and run as an administrator then it should resolve your problem.

Mine seemed to be a permission issue.

unfortunately we can't use in MySQL after INSERT or UPDATE description, like in Oracle

In python there are no arrays, lists are used instead. There are various ways to delete an object from a list:

my_list = [1,2,4,6,7]

del my_list[1] # Removes index 1 from the list
print my_list # [1,4,6,7]
my_list.remove(4) # Removes the integer 4 from the list, not the index 4
print my_list # [1,6,7]
my_list.pop(2) # Removes index 2 from the list

In your case the appropriate method to use is pop, because it takes the index to be removed:

x = object()
y = object()
array = [x, y]
array.pop(0)
# Using the del statement
del array[0]

It's difficult to figure out what you're trying to do with this sample but you're actually on the right track thinking about using classes. I've created a JSFiddle to help demonstrate a slightly better way (I hope) of doing this.

Here's the fiddle: link.

What you do is, instead of working with IDs, you work with classes. In your code sample, there are Oranges and Apples. I treat them as product categories (as I don't really know what your purpose is), with their own ids. So, I mark the product <tr>s with class="cat1" or class="cat2".

I also mark the links with a simple .toggler class. It's not good practice to have onclick attributes on elements themselves. You should 'bind' the events on page load using JavaScript. I do this using jQuery.

$(".toggler").click(function(e){
    // you handle the event here
});

With this format, you are binding an event handler to the click event of links with class toggler. In my code, I add a data-prod-cat attribute to the toggler links to specify which product rows they should control. (The reason for my using a data-* attribute is explained here. You can Google 'html5 data attributes' for more information.)

In the event handler, I do this:

$('.cat'+$(this).attr('data-prod-cat')).toggle();

With this code, I'm actually trying to create a selector like $('.cat1') so I can select rows for a specific product category, and change their visibility. I use $(this).attr('data-prod-cat') this to access the data-prod-cat attribute of the link the user clicks. I use the jQuery toggle function, so that I don't have to write logic like if visible, then hide element, else make it visible like you do in your JS code. jQuery deals with that. The toggle function does what it says and toggles the visibility of the specified element(s).

I hope this was explanatory enough.

string[] lines = File.ReadAllLines(txtProxyListPath.Text);
List<string> list_lines = new List<string>(lines);
Parallel.ForEach(list_lines, line =>
{
    //Your stuff
});

A different approach using concat and drop_duplicates:

import sys
if sys.version_info[0] < 3:
    from StringIO import StringIO
else:
    from io import StringIO
import pandas as pd

DF1 = StringIO("""id   Name   score                    isEnrolled           Comment
111  Jack   2.17                     True                 "He was late to class"
112  Nick   1.11                     False                "Graduated"
113  Zoe    NaN                     True                  " "
""")
DF2 = StringIO("""id   Name   score                    isEnrolled           Comment
111  Jack   2.17                     True                 "He was late to class"
112  Nick   1.21                     False                "Graduated"
113  Zoe    NaN                     False                "On vacation" """)

df1 = pd.read_table(DF1, sep='\s+', index_col='id')
df2 = pd.read_table(DF2, sep='\s+', index_col='id')
#%%
dictionary = {1:df1,2:df2}
df=pd.concat(dictionary)
df.drop_duplicates(keep=False)

Output:

       Name  score isEnrolled      Comment
  id                                      
1 112  Nick   1.11      False    Graduated
  113   Zoe    NaN       True             
2 112  Nick   1.21      False    Graduated
  113   Zoe    NaN      False  On vacation

The Keep It Simple And Stupid(KISS) principle might be useful on this one. Its more faster and easier to check if both passwords match by doing the following:

<div ng-app="app" ng-controller="passwordCheck">
  <form name="signUp" ng-submit="submitForm()" novalidate>
     <input type="password" name="password" ng-model="password" required>
     <input type="password" name="ConfirmPassword" ng-model="passwordconfirm"   required>
     <button type="submit"> Submit</button>
  </form>

  <hr>
  <span>Do they match?</span> {{signUp.password.$viewValue == signUp.confirmPassword.$viewValue}}
    </div>

And Before submitting the form, you can do this in your js

var app = angular.module("app", []);
app.controller("passwordCheck", function($scope) {
   $scope.submitForm = function() {
      if ($scope.signUp.$valid && $scope.signUp.password.$viewValue == $scope.signUp.confirmPassword.$viewValue) {
            alert('Its a match!');
        };
};
});

You can test it in JSfiddle as well.

You should use the $location service

Angular docs:

• Guide to using $location
• $location API

You can use as many joins as you want, however, the more you use the more it will impact performance

Don't try to get them inside its constructor. Try Call them in onDraw() method.

You should initialize yours recordings. You are passing to adapter null

ArrayList<String> recordings = null; //You are passing this null

well looking for a simpler variation I found this:

If @Cybernate's solution doesn't work, try breaking the trigger off in to it's own function so you can reference it.

clickHandler = function(event){
  if (click++ == 49)
    canvas.removeEventListener('click',clickHandler);
}
canvas.addEventListener('click',clickHandler);

Here's my contribution if looking for

h:mm:ss

instead like I was:

function msConversion(millis) {
  let sec = Math.floor(millis / 1000);
  let hrs = Math.floor(sec / 3600);
  sec -= hrs * 3600;
  let min = Math.floor(sec / 60);
  sec -= min * 60;

  sec = '' + sec;
  sec = ('00' + sec).substring(sec.length);

  if (hrs > 0) {
    min = '' + min;
    min = ('00' + min).substring(min.length);
    return hrs + ":" + min + ":" + sec;
  }
  else {
    return min + ":" + sec;
  }
}

In place of the Memory storage engine, one can consider MySQL Cluster. It is said to give similar performance but to support disk-backed operation for durability. I've not tried it, but it looks promising (and been in development for a number of years).

You can find the official MySQL Cluster documentation here.

This displays the name of the current user:

Function Username() As String
    Username = Application.Username
End Function

The property Application.Username holds the name entered with the installation of MS Office.

I've added upon the code submitted by jSnake04 and Dasun herein. I've added code to create lists of objects from JArray instances. It has two-way recursion but as it is functioning on a fixed, finite tree model, there is no risk of stack overflow unless the data is massive.

/// <summary>
/// Deserialize the given JSON string data (<paramref name="data"/>) into a
///   dictionary.
/// </summary>
/// <param name="data">JSON string.</param>
/// <returns>Deserialized dictionary.</returns>
private IDictionary<string, object> DeserializeData(string data)
{
    var values = JsonConvert.DeserializeObject<Dictionary<string, object>>(data);

    return DeserializeData(values);
}

/// <summary>
/// Deserialize the given JSON object (<paramref name="data"/>) into a dictionary.
/// </summary>
/// <param name="data">JSON object.</param>
/// <returns>Deserialized dictionary.</returns>
private IDictionary<string, object> DeserializeData(JObject data)
{
    var dict = data.ToObject<Dictionary<String, Object>>();

    return DeserializeData(dict);
}

/// <summary>
/// Deserialize any elements of the given data dictionary (<paramref name="data"/>) 
///   that are JSON object or JSON arrays into dictionaries or lists respectively.
/// </summary>

private IDictionary<string, object> DeserializeData(IDictionary<string, object> data)
{
    foreach (var key in data.Keys.ToArray()) 
    {
        var value = data[key];

        if (value is JObject)
            data[key] = DeserializeData(value as JObject);

        if (value is JArray)
            data[key] = DeserializeData(value as JArray);
    }

    return data;
}

/// <summary>
/// Deserialize the given JSON array (<paramref name="data"/>) into a list.
/// </summary>
/// <param name="data">Data dictionary.</param>
/// <returns>Deserialized list.</returns>
private IList<Object> DeserializeData(JArray data)
{
    var list = data.ToObject<List<Object>>();

    for (int i = 0; i < list.Count; i++)
    {
        var value = list[i];

        if (value is JObject)
            list[i] = DeserializeData(value as JObject);

        if (value is JArray)
            list[i] = DeserializeData(value as JArray);
    }

    return list;
}

Could do it with :contains() selector as well:

$('#toptitle:contains("Profil")').text("New word");

example: http://jsfiddle.net/niklasvh/xPRzr/

Here is my SQL Server version

DECLARE @ProfileId table(Id bigint)

DELETE FROM AspNetUsers
OUTPUT deleted.ProfileId INTO @ProfileId
WHERE Email = @email

DELETE FROM UserProfiles    
WHERE Id = (Select Id FROM @ProfileId)

one line solution: basic idea:

$('sth').click(function () {
    let COND = $(this).propery == 'cond1' ? 'cond2' : 'cond1';
    doSomeThing(COND);
})

examples on jsfiddle

example 1, changing innerHTML of an element in a toggle-mode:

$('#clickTest1').click(function () {
    $(this).html($(this).html() == 'click Me' ? 'clicked' : 'click Me');
});

example 2, toggling displays between "none" and "inline-block":

$('#clickTest2, #clickTest2 > span').click(function () {
    $(this).children().css('display', $(this).children().css('display') == 'inline-block' ? 'none' : 'inline-block');
});

This happens because your click handler fires before the value of the radio button changes. You need to listen to the change event instead:

<input 
  type="radio" 
  name="optionsRadios" 
  id="optionsRadios2" 
  value=""
  v-model="srStatus" 
  v-on:change="foo"> //here

Also, make sure you really want to call foo() on ready... seems like maybe you don't actually want to do that.

ready:function(){
    foo();
},

You map your dispatcher on *.do:

<servlet-mapping>
   <servlet-name>Dispatcher</servlet-name>
   <url-pattern>*.do</url-pattern>
</servlet-mapping>

but your controller is mapped on an url without .do:

@RequestMapping("/editPresPage")

Try changing this to:

@RequestMapping("/editPresPage.do")

With Swift 5, according to your needs, you can choose one of the 9 following styles in order to have a rounded result from a Double.

#1. Using FloatingPoint rounded() method

In the simplest case, you may use the Double rounded() method.

let roundedValue1 = (0.6844 * 1000).rounded() / 1000
let roundedValue2 = (0.6849 * 1000).rounded() / 1000
print(roundedValue1) // returns 0.684
print(roundedValue2) // returns 0.685

#2. Using FloatingPoint rounded(_:) method

let roundedValue1 = (0.6844 * 1000).rounded(.toNearestOrEven) / 1000
let roundedValue2 = (0.6849 * 1000).rounded(.toNearestOrEven) / 1000
print(roundedValue1) // returns 0.684
print(roundedValue2) // returns 0.685

#3. Using Darwin round function

Foundation offers a round function via Darwin.

import Foundation

let roundedValue1 = round(0.6844 * 1000) / 1000
let roundedValue2 = round(0.6849 * 1000) / 1000
print(roundedValue1) // returns 0.684
print(roundedValue2) // returns 0.685

#4. Using a Double extension custom method built with Darwin round and pow functions

If you want to repeat the previous operation many times, refactoring your code can be a good idea.

import Foundation

extension Double {
    func roundToDecimal(_ fractionDigits: Int) -> Double {
        let multiplier = pow(10, Double(fractionDigits))
        return Darwin.round(self * multiplier) / multiplier
    }
}

let roundedValue1 = 0.6844.roundToDecimal(3)
let roundedValue2 = 0.6849.roundToDecimal(3)
print(roundedValue1) // returns 0.684
print(roundedValue2) // returns 0.685

#5. Using NSDecimalNumber rounding(accordingToBehavior:) method

If needed, NSDecimalNumber offers a verbose but powerful solution for rounding decimal numbers.

import Foundation

let scale: Int16 = 3

let behavior = NSDecimalNumberHandler(roundingMode: .plain, scale: scale, raiseOnExactness: false, raiseOnOverflow: false, raiseOnUnderflow: false, raiseOnDivideByZero: true)

let roundedValue1 = NSDecimalNumber(value: 0.6844).rounding(accordingToBehavior: behavior)
let roundedValue2 = NSDecimalNumber(value: 0.6849).rounding(accordingToBehavior: behavior)

print(roundedValue1) // returns 0.684
print(roundedValue2) // returns 0.685

#6. Using NSDecimalRound(_:_:_:_:) function

import Foundation

let scale = 3

var value1 = Decimal(0.6844)
var value2 = Decimal(0.6849)

var roundedValue1 = Decimal()
var roundedValue2 = Decimal()

NSDecimalRound(&roundedValue1, &value1, scale, NSDecimalNumber.RoundingMode.plain)
NSDecimalRound(&roundedValue2, &value2, scale, NSDecimalNumber.RoundingMode.plain)

print(roundedValue1) // returns 0.684
print(roundedValue2) // returns 0.685

#7. Using NSString init(format:arguments:) initializer

If you want to return a NSString from your rounding operation, using NSString initializer is a simple but efficient solution.

import Foundation

let roundedValue1 = NSString(format: "%.3f", 0.6844)
let roundedValue2 = NSString(format: "%.3f", 0.6849)
print(roundedValue1) // prints 0.684
print(roundedValue2) // prints 0.685

#8. Using String init(format:_:) initializer

Swift’s String type is bridged with Foundation’s NSString class. Therefore, you can use the following code in order to return a String from your rounding operation:

import Foundation

let roundedValue1 = String(format: "%.3f", 0.6844)
let roundedValue2 = String(format: "%.3f", 0.6849)
print(roundedValue1) // prints 0.684
print(roundedValue2) // prints 0.685

#9. Using NumberFormatter

If you expect to get a String? from your rounding operation, NumberFormatter offers a highly customizable solution.

import Foundation

let formatter = NumberFormatter()
formatter.numberStyle = NumberFormatter.Style.decimal
formatter.roundingMode = NumberFormatter.RoundingMode.halfUp
formatter.maximumFractionDigits = 3

let roundedValue1 = formatter.string(from: 0.6844)
let roundedValue2 = formatter.string(from: 0.6849)
print(String(describing: roundedValue1)) // prints Optional("0.684")
print(String(describing: roundedValue2)) // prints Optional("0.685")

Instead, you could try the following. You don't have to go to master; you can directly force push the changes from your branch itself.

As explained above, when you do a rebase, you are changing the history on your branch. As a result, if you try to do a normal git push after a rebase, Git will reject it because there isn't a direct path from the commit on the server to the commit on your branch. Instead, you'll need to use the -f or --force flag to tell Git that yes, you really know what you're doing. When doing force pushes, it is highly recommended that you set your push.default config setting to simple, which is the default in Git 2.0. To make sure that your configuration is correct, run:

$ git config --global push.default simple

Once it's correct, you can just run:

$ git push -f

And check your pull request. It should be updated!

Go to bottom of How to Rebase a Pull Request for more details.

You can add parameter columns or use dict with key which is converted to column name:

np.random.seed(123)
e = np.random.normal(size=10)  
dataframe=pd.DataFrame(e, columns=['a']) 
print (dataframe)
          a
0 -1.085631
1  0.997345
2  0.282978
3 -1.506295
4 -0.578600
5  1.651437
6 -2.426679
7 -0.428913
8  1.265936
9 -0.866740

e_dataframe=pd.DataFrame({'a':e}) 
print (e_dataframe)
          a
0 -1.085631
1  0.997345
2  0.282978
3 -1.506295
4 -0.578600
5  1.651437
6 -2.426679
7 -0.428913
8  1.265936
9 -0.866740

Short story: The 0 tells the parser it's dealing with a constant (and not an identifier/reserved word). Something is still needed to specify the number base: the x is an arbitrary choice.

Long story: In the 60's, the prevalent programming number systems were decimal and octal — mainframes had 12, 24 or 36 bits per byte, which is nicely divisible by 3 = log2(8).

The BCPL language used the syntax 8 1234 for octal numbers. When Ken Thompson created B from BCPL, he used the 0 prefix instead. This is great because

1. an integer constant now always consists of a single token,
2. the parser can still tell right away it's got a constant,
3. the parser can immediately tell the base (0 is the same in both bases),
4. it's mathematically sane (00005 == 05), and
5. no precious special characters are needed (as in #123).

When C was created from B, the need for hexadecimal numbers arose (the PDP-11 had 16-bit words) and all of the points above were still valid. Since octals were still needed for other machines, 0x was arbitrarily chosen (00 was probably ruled out as awkward).

C# is a descendant of C, so it inherits the syntax.

Combined Solutions in Extensions class:

public static class Extensions {

    public static byte[] ToByteArray(this object obj) {
        var size = Marshal.SizeOf(data);
        var bytes = new byte[size];
        var ptr = Marshal.AllocHGlobal(size);
        Marshal.StructureToPtr(data, ptr, false);
        Marshal.Copy(ptr, bytes, 0, size);
        Marshal.FreeHGlobal(ptr);
        return bytes;
   }

    public static string Serialize(this object obj) {
        return JsonConvert.SerializeObject(obj);
   }

}

In your appDelegate.m inside your didFinishLaunchingWithOptions

//authenticatedUser: check from NSUserDefaults User credential if its present then set your navigation flow accordingly

if (authenticatedUser) 
{
    self.window.rootViewController = [[UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]] instantiateInitialViewController];        
}
else
{
    UIViewController* rootController = [[UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]] instantiateViewControllerWithIdentifier:@"LoginViewController"];
    UINavigationController* navigation = [[UINavigationController alloc] initWithRootViewController:rootController];

    self.window.rootViewController = navigation;
}

In SignUpViewController.m file

- (IBAction)actionSignup:(id)sender
{
    AppDelegate *appDelegateTemp = [[UIApplication sharedApplication]delegate];

    appDelegateTemp.window.rootViewController = [[UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]] instantiateInitialViewController];
}

In file MyTabThreeViewController.m

- (IBAction)actionLogout:(id)sender {

    // Delete User credential from NSUserDefaults and other data related to user

    AppDelegate *appDelegateTemp = [[UIApplication sharedApplication]delegate];

    UIViewController* rootController = [[UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]] instantiateViewControllerWithIdentifier:@"LoginViewController"];

    UINavigationController* navigation = [[UINavigationController alloc] initWithRootViewController:rootController];
    appDelegateTemp.window.rootViewController = navigation;

}

Swift 4 Version

didFinishLaunchingWithOptions in app delegate assuming your initial view controller is the signed in TabbarController.

if Auth.auth().currentUser == nil {
        let rootController = UIStoryboard(name: "Main", bundle: Bundle.main).instantiateViewController(withIdentifier: "WelcomeNavigation")
        self.window?.rootViewController = rootController
    }

    return true

In Sign up view controller:

@IBAction func actionSignup(_ sender: Any) {
let appDelegateTemp = UIApplication.shared.delegate as? AppDelegate
appDelegateTemp?.window?.rootViewController = UIStoryboard(name: "Main", bundle: Bundle.main).instantiateInitialViewController()
}

MyTabThreeViewController

 //Remove user credentials
guard let appDel = UIApplication.shared.delegate as? AppDelegate else { return }
        let rootController = UIStoryboard(name: "Main", bundle: Bundle.main).instantiateViewController(withIdentifier: "WelcomeNavigation")
        appDel.window?.rootViewController = rootController

Yes, this is an old post. Regardless, someone may find it useful. Here is another way to send parameters to event handlers.

//click handler
function add_event(event, paramA, paramB)
{
    //do something with your parameters
    alert(paramA ? 'paramA:' + paramA : '' + paramB ? '  paramB:' + paramB : '');
}

//bind handler to click event
$('.leadtoscore').click(add_event);
...
//once you've processed some data and know your parameters, trigger a click event.
//In this case, we will send 'myfirst' and 'mysecond' as parameters
$('.leadtoscore').trigger('click', {'myfirst', 'mysecond'});

//or use variables
var a = 'first',
    b = 'second';

$('.leadtoscore').trigger('click', {a, b});
$('.leadtoscore').trigger('click', {a});

I have on several projects.

The biggest difference in my opinion

• jQuery UI is fallback safe, it works correctly and looks good in old browsers, where Bootstrap is based on CSS3 which basically means GREAT in new browsers, not so great in old

• Update frequency: Bootstrap is getting some great big updates with awesome new features, but sadly they might break previous code, so you can't just install bootstrap and update when there is a new major release, it basically requires a lot of new coding

• jQuery UI is based on good html structure with transformations from JavaScript, while Bootstrap is based on visually and customizable inline structure. (calling a widget in JQUERY UI, defining it in Bootstrap)

So what to choose?

That always depends on the type of project you are working on. Is cool and fast looking widgets better, or are your users often using old browsers?

I always end up using both, so I can use the best of both worlds.

Here are the links to both frameworks, if you decide to use them.

1. jQuery UI
2. Bootstrap

From the Oracle Reference:

The default locale of your application is determined in three ways. First, unless you have explicitly changed the default, the Locale.getDefault() method returns the locale that was initially determined by the Java Virtual Machine (JVM) when it first loaded. That is, the JVM determines the default locale from the host environment. The host environment's locale is determined by the host operating system and the user preferences established on that system.

Second, on some Java runtime implementations, the application user can override the host's default locale by providing this information on the command line by setting the user.language, user.country, and user.variant system properties.

Third, your application can call the Locale.setDefault(Locale) method. The setDefault(Locale aLocale) method lets your application set a systemwide (actually VM-wide) resource. After you set the default locale with this method, subsequent calls to Locale.getDefault() will return the newly set locale.

Short answer - no.

You will only be charged for the time that your instance is up and running, in hour increments. If you are using other services in conjunction you may be charged for those but it would be separate from your server instance.

Same-origin policy

You can't access an <iframe> with different origin using JavaScript, it would be a huge security flaw if you could do it. For the same-origin policy browsers block scripts trying to access a frame with a different origin.

Origin is considered different if at least one of the following parts of the address isn't maintained:

protocol://hostname:port/...

Protocol, hostname and port must be the same of your domain if you want to access a frame.

^{NOTE: Internet Explorer is known to not strictly follow this rule, see here for details.}

Examples

Here's what would happen trying to access the following URLs from http://www.example.com/home/index.html

URL                                             RESULT 
http://www.example.com/home/other.html       -> Success 
http://www.example.com/dir/inner/another.php -> Success 
http://www.example.com:80                    -> Success (default port for HTTP) 
http://www.example.com:2251                  -> Failure: different port 
http://data.example.com/dir/other.html       -> Failure: different hostname 
https://www.example.com/home/index.html:80   -> Failure: different protocol
ftp://www.example.com:21                     -> Failure: different protocol & port 
https://google.com/search?q=james+bond       -> Failure: different protocol, port & hostname 

Workaround

Even though same-origin policy blocks scripts from accessing the content of sites with a different origin, if you own both the pages, you can work around this problem using window.postMessage and its relative message event to send messages between the two pages, like this:

• In your main page:

  const frame = document.getElementById('your-frame-id');
  frame.contentWindow.postMessage(/*any variable or object here*/, 'http://your-second-site.com');
  

  The second argument to postMessage() can be '*' to indicate no preference about the origin of the destination. A target origin should always be provided when possible, to avoid disclosing the data you send to any other site.

• In your <iframe> (contained in the main page):

  window.addEventListener('message', event => {
      // IMPORTANT: check the origin of the data! 
      if (event.origin.startsWith('http://your-first-site.com')) { 
          // The data was sent from your site.
          // Data sent with postMessage is stored in event.data:
          console.log(event.data); 
      } else {
          // The data was NOT sent from your site! 
          // Be careful! Do not use it. This else branch is
          // here just for clarity, you usually shouldn't need it.
          return; 
      } 
  }); 
  

This method can be applied in both directions, creating a listener in the main page too, and receiving responses from the frame. The same logic can also be implemented in pop-ups and basically any new window generated by the main page (e.g. using window.open()) as well, without any difference.

Disabling same-origin policy in your browser

There already are some good answers about this topic (I just found them googling), so, for the browsers where this is possible, I'll link the relative answer. However, please remember that disabling the same-origin policy will only affect your browser. Also, running a browser with same-origin security settings disabled grants any website access to cross-origin resources, so it's very unsafe and should NEVER be done if you do not know exactly what you are doing (e.g. development purposes).

• Google Chrome
• Mozilla Firefox
• Safari
• Opera
• Microsoft Edge: not possible
• Microsoft Internet Explorer

The simplest answer!

P.S. the one who wrote the document of argparse is foolish

python code:

import argparse
parser = argparse.ArgumentParser(description='')
parser.add_argument('--o_dct_fname',type=str)
parser.add_argument('--tp',type=str)
parser.add_argument('--new_res_set',type=int)
args = parser.parse_args()
o_dct_fname = args.o_dct_fname
tp = args.tp
new_res_set = args.new_res_set

running code

python produce_result.py --o_dct_fname o_dct --tp father_child --new_res_set 1

I've actually used your first approach with quite some success, but in a slightly different ways that I think would solve some of your problems:

1. Keep the entire schema and scripts for creating it in source control so that anyone can create the current database schema after a check out. In addition, keep sample data in data files that get loaded by part of the build process. As you discover data that causes errors, add it to your sample data to check that errors don't re-emerge.

2. Use a continuous integration server to build the database schema, load the sample data, and run tests. This is how we keep our test database in sync (rebuilding it at every test run). Though this requires that the CI server have access and ownership of its own dedicated database instance, I say that having our db schema built 3 times a day has dramatically helped find errors that probably would not have been found till just before delivery (if not later). I can't say that I rebuild the schema before every commit. Does anybody? With this approach you won't have to (well maybe we should, but its not a big deal if someone forgets).

3. For my group, user input is done at the application level (not db) so this is tested via standard unit tests.

Loading Production Database Copy:
This was the approach that was used at my last job. It was a huge pain cause of a couple of issues:

1. The copy would get out of date from the production version
2. Changes would be made to the copy's schema and wouldn't get propagated to the production systems. At this point we'd have diverging schemas. Not fun.

Mocking Database Server:
We also do this at my current job. After every commit we execute unit tests against the application code that have mock db accessors injected. Then three times a day we execute the full db build described above. I definitely recommend both approaches.

This is the best way.

1. First put your cursor on the member and click F2.

2. Then type the new name and hit the Enter key. This will rename all of the occurrences in every file in your project.

This is ideal for when you want to rename across multiple files. For example, you may want to rename a publicly accessible function on an Angular service and have everywhere that uses it get updated.

For more great tools I highly recommend: https://johnpapa.net/refactoring-with-visual-studio-code/

var isDate_ = function(input) {
        var status = false;
        if (!input || input.length <= 0) {
          status = false;
        } else {
          var result = new Date(input);
          if (result == 'Invalid Date') {
            status = false;
          } else {
            status = true;
          }
        }
        return status;
      }

this function returns bool value of whether the input given is a valid date or not. ex:

if(isDate_(var_date)) {
  // statements if the date is valid
} else {
  // statements if not valid
}

arrayList.set(location,newValue); location= where u wnna insert, newValue= new element you are inserting.

notify is optional, depends on conditions.

This is a very old question, but I do not feel that the benefits of ASMX have been fairly portrayed. While not terribly flexible, ASMX web services are very simple to use and understand. While WCF is more flexible, it is also more complex to stand up and configure.

ASMX web services are ready to stand up and add as a webservice reference as soon as you add the file. (assuming your project builds)

For the simple development workflow of create webservice -> run webservice -> add webservice reference, an ASMX webservice has very little that can go wrong, not much that you can misconfigure, and that is it's strength.

In response to those that assert that WCF replaces ASMX, I would reply that WCF would need to add a streamlined K.I.S.S. configuration mode in order to completely replace ASMX.

Example web.config for an ASMX webservice:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <appSettings />
  <system.web>
    <compilation targetFramework="4.5" />
    <httpRuntime targetFramework="4.5" />
  </system.web>
</configuration>

http://www.eclipse.org/cdt/ ^Give that a try

I have not used the CDT for eclipse but I do use Eclipse Java for Ubuntu 12.04 and it works wonders.

The suggested solutions could be optimized using commons.io, handling the error stream, and using Exceptions. I would suggest to wrap like this for use in Java 8 or later:

public static List<String> execute(final String command) throws ExecutionFailedException, InterruptedException, IOException {
    try {
        return execute(command, 0, null, false);
    } catch (ExecutionTimeoutException e) { return null; } /* Impossible case! */
}

public static List<String> execute(final String command, final long timeout, final TimeUnit timeUnit) throws ExecutionFailedException, ExecutionTimeoutException, InterruptedException, IOException {
    return execute(command, 0, null, true);
}

public static List<String> execute(final String command, final long timeout, final TimeUnit timeUnit, boolean destroyOnTimeout) throws ExecutionFailedException, ExecutionTimeoutException, InterruptedException, IOException {
    Process process = new ProcessBuilder().command("bash", "-c", command).start();
    if(timeUnit != null) {
        if(process.waitFor(timeout, timeUnit)) {
            if(process.exitValue() == 0) {
                return IOUtils.readLines(process.getInputStream(), StandardCharsets.UTF_8);
            } else {
                throw new ExecutionFailedException("Execution failed: " + command, process.exitValue(), IOUtils.readLines(process.getInputStream(), StandardCharsets.UTF_8));
            }
        } else {
            if(destroyOnTimeout) process.destroy();
            throw new ExecutionTimeoutException("Execution timed out: " + command);
        }
    } else {
        if(process.waitFor() == 0) {
            return IOUtils.readLines(process.getInputStream(), StandardCharsets.UTF_8);
        } else {
            throw new ExecutionFailedException("Execution failed: " + command, process.exitValue(), IOUtils.readLines(process.getInputStream(), StandardCharsets.UTF_8));
        }
    }
}

public static class ExecutionFailedException extends Exception {

    private static final long serialVersionUID = 1951044996696304510L;

    private final int exitCode;
    private final List<String> errorOutput;

    public ExecutionFailedException(final String message, final int exitCode, final List<String> errorOutput) {
        super(message);
        this.exitCode = exitCode;
        this.errorOutput = errorOutput;
    }

    public int getExitCode() {
        return this.exitCode;
    }

    public List<String> getErrorOutput() {
        return this.errorOutput;
    }

}

public static class ExecutionTimeoutException extends Exception {

    private static final long serialVersionUID = 4428595769718054862L;

    public ExecutionTimeoutException(final String message) {
        super(message);
    }

}

Here are the three web pages on which we found the answer. The most difficult part was setting up static ports for SQLEXPRESS.

Provisioning a SQL Server Virtual Machine on Windows Azure. These initial instructions provided 25% of the answer.

How to Troubleshoot Connecting to the SQL Server Database Engine. Reading this carefully provided another 50% of the answer.

How to configure SQL server to listen on different ports on different IP addresses?. This enabled setting up static ports for named instances (eg SQLEXPRESS.) It took us the final 25% of the way to the answer.

At this time, I did it by using:

yarn test TestFileName.spec.js

You shouldn't put the complete path. That works for me on a Windows 10 machine.

It is very important that AJAX requests retain session. The easiest example is when you try to do an AJAX request for the admin panel, let's say. Of course that you will protect the page that you make the request to, not to accessible by others who don't have the session you get after administrator login. Makes sense?

You can use this function:

function mapMap(map, fn) {
  return new Map(Array.from(map, ([key, value]) => [key, fn(value, key, map)]));
}

usage:

var map1 = new Map([["A", 2], ["B", 3], ["C", 4]]);

var map2 = mapMap(map1, v => v * v);

console.log(map1, map2);
/*
Map { A ? 2, B ? 3, C ? 4 }
Map { A ? 4, B ? 9, C ? 16 }
*/

It's worth noting that an OS has one queue for both System.err and System.out. Consider the following code:

public class PrintQueue {
    public static void main(String[] args) {
        for(int i = 0; i < 100; i++) {
            System.out.println("out");
            System.err.println("err");
        }
    }
}

If you compile and run the program, you will see that the order of outputs in console is mixed up.

An OS will remain right order if you work either with System.out or System.err only. But it can randomly choose what to print next to console, if you use both of these.

Even in this code snippet you can see that the order is mixed up sometimes:

public class PrintQueue {
    public static void main(String[] args) {
        System.out.println("out");
        System.err.println("err");
    }
}

Call the std::exit function.   

Starting with CMake 3.15, the correct way of achieving this would be using:

cmake --install <dir> --prefix "/usr"

After converting your varchar2 date to a true date datatype, then convert back to varchar2 with the desired mask:

to_char(to_date('01/02/2012','MM/DD/YYYY'),'WW')

If you want the week number in a number datatype, you can wrap the statement in to_number():

to_number(to_char(to_date('01/02/2012','MM/DD/YYYY'),'WW'))

However, you have several week number options to consider:

WW  Week of year (1-53) where week 1 starts on the first day of the year and continues to the seventh day of the year.
W   Week of month (1-5) where week 1 starts on the first day of the month and ends on the seventh.
IW  Week of year (1-52 or 1-53) based on the ISO standard.

If you want to do it in multiple, easy-to-remember commands:

1. list stopped containers:

docker ps -a

2. copy the name or the container id of the container you want to attach to, and start the container with:

docker start -i <name/id>

The -i flag tells docker to attach to the container's stdin.

If the container wasn't started with an interactive shell to connect to, you need to do this to run a shell:

docker start <name/id>
docker exec -it <name/id> /bin/sh

The /bin/sh is the shell usually available with alpine-based images.

If your platform matrix supports Java 7 then you can use like below

List<List<String>> myList = new ArrayList<>();

Okay, per http://www.oracle.com/technology/tech/globalization/htdocs/nls_lang%20faq.htm:

NLS_LANG cannot be changed by ALTER SESSION, NLS_LANGUAGE and NLS_TERRITORY can. However NLS_LANGUAGE and /or NLS_TERRITORY cannot be set as "standalone" parameters in the environment or registry on the client.

Evidently the "right" solution is, before logging into Oracle at all, setting the following environment variable:

export NLS_LANG=AMERICAN_AMERICA.UTF8

Oracle gets a big fat F for usability.

Whatever advice path you go down, make a copy of your project folder, and rename the external most one to reflect what XCode version it is being opened in.

To enable GZIP compression, you need to modify the configuration of the embedded Tomcat instance. To do so, you declare a EmbeddedServletContainerCustomizer bean in your Java configuration and then register a TomcatConnectorCustomizer with it.

For example:

@Bean
public EmbeddedServletContainerCustomizer servletContainerCustomizer() {
    return new EmbeddedServletContainerCustomizer() {
        @Override
        public void customize(ConfigurableEmbeddedServletContainerFactory factory) {
            ((TomcatEmbeddedServletContainerFactory) factory).addConnectorCustomizers(new TomcatConnectorCustomizer() {
                @Override
                public void customize(Connector connector) {
                    AbstractHttp11Protocol httpProtocol = (AbstractHttp11Protocol) connector.getProtocolHandler();
                    httpProtocol.setCompression("on");
                    httpProtocol.setCompressionMinSize(64);
                }
            });
        }
    };
}

See the Tomcat documentation for more details on the various compression configuration options that are available.

You say that you want to selectively enable compression. Depending on your selection criteria, then the above approach may be sufficient. It enables you to control compression by the request's user-agent, the response's size, and the response's mime type.

If this doesn't meet your needs then I believe you will have to perform the compression in your controller and return a byte[] response with a gzip content-encoding header.

As of iOS 5 Apple provides a private api method to create labels with soft shadows. The labels are very fast: I'm using dozens at the same time in a series of transparent views and there is no slowdown in scrolling animation.

This is only useful for non-App Store apps (obviously) and you need the header file.

$SBBulletinBlurredShadowLabel = NSClassFromString("SBBulletinBlurredShadowLabel");

CGRect frame = CGRectZero;

SBBulletinBlurredShadowLabel *label = [[[$SBBulletinBlurredShadowLabel alloc] initWithFrame:frame] autorelease];
label.backgroundColor = [UIColor clearColor];
label.textColor = [UIColor whiteColor];
label.font = [UIFont boldSystemFontOfSize:12];
label.text = @"I am a label with a soft shadow!";
[label sizeToFit];

There are some really good answers given already, but I wanted to throw in my two cents. Here is a very simple way to convert a view object into a entity. The simple idea is that only the properties that exist in the view model get written to the entity. This is similar to @Anik Islam Abhi's answer, but has null propagation.

public static T MapVMUpdate<T>(object updatedVM, T original)
{
    PropertyInfo[] originalProps = original.GetType().GetProperties();
    PropertyInfo[] vmProps = updatedVM.GetType().GetProperties();
    foreach (PropertyInfo prop in vmProps)
    {
        PropertyInfo projectProp = originalProps.FirstOrDefault(x => x.Name == prop.Name);
        if (projectProp != null)
        {
            projectProp.SetValue(original, prop.GetValue(updatedVM));
        }
    }
    return original;
}

Pros

• Views don't need to have all the properties of the entity.
• You never have to update code when you add remove a property to a view.
• Completely generic

Cons

• 2 hits on the database, one to load the original entity, and one to save it.

To me the simplicity and low maintenance requirements of this approach outweigh the added database call.

Since the tags only say iOS i will post the answer for Swift 1.2 and iOs 8.4, add these in your view controller swift class:

// MARK: - Close keyboard when touching somewhere else
override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {

    self.view.endEditing(true)

}

// MARK: - Close keyboard when return pressed
func textFieldShouldReturn(textField: UITextField!) -> Bool {

    textField.resignFirstResponder()

    return true
}
// MARK: -

Also do not forget to add UITextFieldDelegate in the class declaration and set your text fields delegate to self (the view).

If this helps, you can also use FileSystemObject to retrieve all subfolders of a folder. You need to check the reference "Microsot Scripting Runtime" to get Intellisense and use the "new" keyword.

Sub GetSubFolders()

    Dim fso As New FileSystemObject
    Dim f As Folder, sf As Folder

    Set f = fso.GetFolder("D:\Proj\")
    For Each sf In f.SubFolders
        'Code inside
    Next

End Sub

var y_axis_name=[];

 for(var point in jsonData[0].data)
              { 
                y_axis_name.push(point);

              }

y_axis_name is having all the key name

It's not immediately obvious from the documentation why the following does not work:

<span style={font-size: 1.7} class="glyphicon glyphicon-remove-sign"></span>

But when doing it entirely inline:

• You need double curly brackets
• You don't need to put your values in quotes
• React will add some default if you omit "em"
• Remember to camelCase style names that have dashes in CSS - e.g. font-size becomes fontSize:
• class is className

The correct way looks like this:

<span style={{fontSize: 1.7 + "em"}} className="glyphicon glyphicon-remove-sign"></span>

Use -

new Select(driver.findElement(By.id("gender"))).selectByVisibleText("Germany");

Of course, you need to import org.openqa.selenium.support.ui.Select;

Just use: (easy as pie)

double number = 651.5176515121351;

number = Math.round(number * 100);
number = number/100;

The output will be 651.52

Since Java 8 you can use the Math.floorMod() method:

Math.floorMod(-1, 2); //== 1

Note: If the modulo-value (here 2) is negative, all output values will be negative too. :)

1. Right click on properties of Console Application.
2. Check Target framework
3. If it is .Net framework 4.0 Client Profile then change it to .Net Framework 4.0

It works now

Please use the below code and let me know

try{

            Class.forName("com.mysql.jdbc.Driver").newInstance();
            con = DriverManager.getConnection(c, "root", "MyNewPass");
            System.out.println("connection done");


            PreparedStatement ps=con.prepareStatement(q);
            System.out.println(q);
            rs=ps.executeQuery();
            System.out.println("done2");
            while (rs.next()) {
               System.out.println(rs.getString(1));
               System.out.println(rs.getString(2));

            }

         response.sendRedirect("myfolder/welcome.jsp"); // wherever you wanna redirect this page.

        }
            catch (Exception e) {
                // TODO: handle exception
                System.out.println("Failed");
            }

myfolder/welcome.jsp is the relative path of your jsp page. So, change it as per your jsp page path.

 Color red = Color.FromName("Red");   

The MSDN doesn't say one way or another, so there's a good chance that it is case-sensitive. (UPDATE: Apparently, it is not.)

As far as I can tell, ColorTranslator.FromHtml is also.

If Color.FromName cannot find a match, it returns new Color(0,0,0);

If ColorTranslator.FromHtml cannot find a match, it throws an exception.

UPDATE:

Since you're using Microsoft.Xna.Framework.Graphics.Color, this gets a bit tricky:

using XColor = Microsoft.Xna.Framework.Graphics.Color;
using CColor = System.Drawing.Color;

 CColor clrColor = CColor.FromName("Red"); 
 XColor xColor = new XColor(clrColor.R, clrColor.G, clrColor.B, clrColor.A);

git diff <a-commit> <another-commit> path

Example:

git diff commit1 commit2 config/routes.rb

It shows the difference on that file between those commits.

I've come up with next method:

function isSequential(array $list): bool
{
    $i = 0;
    $count = count($list);
    while (array_key_exists($i, $list)) {
        $i += 1;
        if ($i === $count) {
            return true;
        }
    }

    return false;
}


var_dump(isSequential(array())); // false
var_dump(isSequential(array('a', 'b', 'c'))); // true
var_dump(isSequential(array("0" => 'a', "1" => 'b', "2" => 'c'))); // true
var_dump(isSequential(array("1" => 'a', "0" => 'b', "2" => 'c'))); // true
var_dump(isSequential(array("1a" => 'a', "0b" => 'b', "2c" => 'c'))); // false
var_dump(isSequential(array("a" => 'a', "b" => 'b', "c" => 'c'))); // false

*Note empty array is not considered a sequential array, but I think it's fine since empty arrays is like 0 - doesn't matter it's plus or minus, it's empty.

Here are the advantages of this method compared to some listed above:

• It does not involve copying of arrays (someone mentioned in this gist https://gist.github.com/Thinkscape/1965669 that array_values does not involve copying - what!?? It certainly does - as will be seen below)
• It's faster for bigger arrays and more memory friendly at the same time

I've used benchmark kindly provided by Artur Bodera, where I changed one of the arrays to 1M elements (array_fill(0, 1000000, uniqid()), // big numeric array).

Here are the results for 100 iterations:

PHP 7.1.16 (cli) (built: Mar 31 2018 02:59:59) ( NTS )

Initial memory: 32.42 MB
Testing my_method (isset check) - 100 iterations
  Total time: 2.57942 s
  Total memory: 32.48 MB

Testing method3 (array_filter of keys) - 100 iterations
  Total time: 5.10964 s
  Total memory: 64.42 MB

Testing method1 (array_values check) - 100 iterations
  Total time: 3.07591 s
  Total memory: 64.42 MB

Testing method2 (array_keys comparison) - 100 iterations
  Total time: 5.62937 s
  Total memory: 96.43 MB

*Methods are ordered based on their memory consumption

**I used echo " Total memory: " . number_format(memory_get_peak_usage()/1024/1024, 2) . " MB\n"; to display memory usage

Let's say you have an Employee class that has a method greet. When the greet method is called it simply prints Hello everyone!. So that is the expected behavior of greet method

public class Employee {

    void greet() {
        System.out.println("Hello everyone!");
    }
}

Now, let GrumpyEmployee subclass Employee and override greet method as shown below.

public class GrumpyEmployee extends Employee {

    @Override
    void greet() {
        System.out.println("Get lost!");
    }
}

Now in the below code have a look at the sayHello method. It takes Employee instance as a parameter and calls the greet method hoping that it would say Hello everyone! But what we get is Get lost!. This change in behavior is because of Employee grumpyEmployee = new GrumpyEmployee();

public class TestFinal {
    static Employee grumpyEmployee = new GrumpyEmployee();

    public static void main(String[] args) {
        TestFinal testFinal = new TestFinal();
        testFinal.sayHello(grumpyEmployee);
    }

    private void sayHello(Employee employee) {
        employee.greet(); //Here you would expect a warm greeting, but what you get is "Get lost!"
    }
}

This situation can be avoided if the Employee class was made final. Just imagine the amount of chaos a cheeky programmer could cause if String Class was not declared as final.

You can use map :

List<String> names = 
    personList.stream()
              .map(Person::getName)
              .collect(Collectors.toList());

EDIT :

In order to combine the Lists of friend names, you need to use flatMap :

List<String> friendNames = 
    personList.stream()
              .flatMap(e->e.getFriends().stream())
              .collect(Collectors.toList());
