In my case I was trying to pass a shell command to a container. In which case only the first word was interpreted. Ensure that you're not running:

mysql

as opposed to:

mysql -uroot -ppassword schemaname

perhaps try quoting:

'mysql -uroot -ppassword schemaname'

Use a JSON parser, like JSON.NET

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

Even better approach using array's join method

var countries = ['United States', 'Canada', 'Argentina', 'Armenia'];
var list = '<ul class="myList"><li class="ui-menu-item" role="menuitem"><a class="ui-all" tabindex="-1">' + countries.join('</a></li><li>') + '</li></ul>';

For those using CodeIgniter, there's a built-in Date Helper function called timezone_menu. These:

$this->load->helper('date');
echo timezone_menu('GMT', 'form-control', 'dropdown-name', ['id' => 'ci-timezone']);

Produce the following output:

Auto-correlation comes in two versions: statistical and convolution. They both do the same, except for a little detail: The statistical version is normalized to be on the interval [-1,1]. Here is an example of how you do the statistical one:

def acf(x, length=20):
    return numpy.array([1]+[numpy.corrcoef(x[:-i], x[i:])[0,1]  \
        for i in range(1, length)])

This comes down to browser image support; it looks like the only mainstream browser that supports tiff is Safari:

http://en.wikipedia.org/wiki/Comparison_of_web_browsers#Image_format_support

Where are you getting the tiff images from? Is it possible for them to be generated in a different format?

If you have a static set of images then I'd recommend using something like PaintShop Pro to batch convert them, changing the format.

If this isn't an option then there might be some mileage in looking for a pre-written Java applet (or another browser plugin) that can display the images in the browser.

Assuming that your profile in ~/aws/config is using the region (instead of AZ as per your original question); the other cause is your client's inability to connect to s3.us-east-1.amazonaws.com. In my case, I was unable to resolve that DNS name due to an error in my network configuration. Fixing the DNS issue solved my problem.

I faced the same issue with a Foundation menu. align-self: center; didn't work for me.

My solution was to wrap the image with a <div style="display: inline-table;">...</div>

Another solution is to register a default namespace with ControllerBuilder. Since we had lots of routes in our main application and only a single generic route in our areas (where we were already specifying a namespace), we found this to be the easiest solution:

ControllerBuilder.Current
     .DefaultNamespaces.Add("YourApp.Controllers");

It's easier than you wonder.

If you are working with a separated by semicolon file and header too:

$ (head -n1 file.csv && sort file.csv | grep -v <header>) | column -s";" -t

If you are working with array (using tab as separator):

for((i=0;i<array_size;i++));
do

   echo stringarray[$i] $'\t' numberarray[$i] $'\t' anotherfieldarray[$i] >> tmp_file.csv

done;

cat file.csv | column -t

Something like this could be used, and still maintaining meanings of return (to return control signals) and echo (to return information) and logging statements (to print debug/info messages).

                v_verbose_f=$(tempfile)
                tail -f $v_verbose_f &
                FLAG_BGPID="$!"
        fi
}

d_verbose() {
        if [[ x"$FLAG_BGPID" != "x" ]]; then
                kill $FLAG_BGPID > /dev/null
                FLAG_BGPID=""
                rm -f $v_verbose_f > /dev/null
        fi
}

init() {
        e_verbose

        trap cleanup SIGINT SIGQUIT SIGKILL SIGSTOP SIGTERM SIGHUP SIGTSTP
}

cleanup() {
        d_verbose
}

init

fun1() {
    echo "got $1" >> $v_verbose_f
    echo "got $2" >> $v_verbose_f
    echo "$(( $1 + $2 ))"
    return 0
}

a=$(fun1 10 20)
if [[ $? -eq 0 ]]; then
    echo ">>sum: $a"
else
    echo "error: $?"
fi
cleanup

In here, I'm redirecting debug messages to separate file, that is watched by tail, and if there is any changes then printing the change, trap is used to make sure that background process always ends.

This behavior can also be achieved using redirection to /dev/stderr, But difference can be seen at the time of piping output of one command to input of other command.

Just an update.

Now if it's a github repository then using just a github shorthand is enough if you do not mind the version of course.

@Michael Durrant's answer ably covers the shell itself, but the shell environment also includes the various commands you use in the shell and these are going to be similar -- but not identical -- between OS X and linux. In general, both will have the same core commands and features (especially those defined in the Posix standard), but a lot of extensions will be different.

For example, linux systems generally have a useradd command to create new users, but OS X doesn't. On OS X, you generally use the GUI to create users; if you need to create them from the command line, you use dscl (which linux doesn't have) to edit the user database (see here). (Update: starting in macOS High Sierra v10.13, you can use sysadminctl -addUser instead.)

Also, some commands they have in common will have different features and options. For example, linuxes generally include GNU sed, which uses the -r option to invoke extended regular expressions; on OS X, you'd use the -E option to get the same effect. Similarly, in linux you might use ls --color=auto to get colorized output; on macOS, the closest equivalent is ls -G.

EDIT: Another difference is that many linux commands allow options to be specified after their arguments (e.g. ls file1 file2 -l), while most OS X commands require options to come strictly first (ls -l file1 file2).

Finally, since the OS itself is different, some commands wind up behaving differently between the OSes. For example, on linux you'd probably use ifconfig to change your network configuration. On OS X, ifconfig will work (probably with slightly different syntax), but your changes are likely to be overwritten randomly by the system configuration daemon; instead you should edit the network preferences with networksetup, and then let the config daemon apply them to the live network state.

Setting Up the database

public class DatabaseHelper extends SQLiteOpenHelper {
    // Database Version
    private static final int DATABASE_VERSION = 1;

    // Database Name
    private static final String DATABASE_NAME = "database_name";

    // Table Names
    private static final String DB_TABLE = "table_image";

    // column names
    private static final String KEY_NAME = "image_name";
    private static final String KEY_IMAGE = "image_data";

    // Table create statement
    private static final String CREATE_TABLE_IMAGE = "CREATE TABLE " + DB_TABLE + "("+ 
                       KEY_NAME + " TEXT," + 
                       KEY_IMAGE + " BLOB);";

    public DatabaseHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {

        // creating table
        db.execSQL(CREATE_TABLE_IMAGE);
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // on upgrade drop older tables
        db.execSQL("DROP TABLE IF EXISTS " + DB_TABLE);

        // create new table
        onCreate(db);
    }
}

Insert in the Database:

public void addEntry( String name, byte[] image) throws SQLiteException{
    SQLiteDatabase database = this.getWritableDatabase();
    ContentValues cv = new  ContentValues();
    cv.put(KEY_NAME,    name);
    cv.put(KEY_IMAGE,   image);
    database.insert( DB_TABLE, null, cv );
}

Retrieving data:

 byte[] image = cursor.getBlob(1);

Note:

1. Before inserting into database, you need to convert your Bitmap image into byte array first then apply it using database query.
2. When retrieving from database, you certainly have a byte array of image, what you need to do is to convert byte array back to original image. So, you have to make use of BitmapFactory to decode.

Below is an Utility class which I hope could help you:

public class DbBitmapUtility {

    // convert from bitmap to byte array
    public static byte[] getBytes(Bitmap bitmap) {
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        bitmap.compress(CompressFormat.PNG, 0, stream);
        return stream.toByteArray();
    }

    // convert from byte array to bitmap
    public static Bitmap getImage(byte[] image) {
        return BitmapFactory.decodeByteArray(image, 0, image.length);
    }
}

So this may not be the issue for you, but I was struggling with this error. I discovered what was causing my problem, though I can't really explain as to why.

For me, mysqli_connect was working fine where the connection was made on pages in any various sub-directory. For some reason though, the same code referenced on pages in the root directory was returning this error. The strange thing is that it was working fine on my localhost environment in MAMP in the root directory, however on my shared host it was not.

After struggling to figure out what was giving me "Error 500" white screen from this "PHP Fatal Error," I went through the code and stumbled upon this code in the error handling that was suggested by the PHP Manual (https://www.php.net/manual/en/mysqli.error.php).

if (!mysqli_query($link, "SET a=1")) {
    printf("Error message: %s\n", mysqli_error($link));
}

I randomly decided to remove it and, voila, connection to the database working in root directories. Maybe someone smarter than me can explain this, for anyone struggling with a similar issue.

No, don't do it that way.

From your Eclipse workspace, right click your project on the left pane -> Properties -> Java Build Path -> Add Jars -> add your jars here.

Tadaa!! :)

I had the same problem. The only thing that solved it was merge the content of META-INF/spring.handler and META-INF/spring.schemas of each spring jar file into same file names under my META-INF project.

This two threads explain it better:

• Thread: unable to locate Spring NamespaceHandler for XML schema namespace

"I'd like to paste yanked text into Vim command line."

While the top voted answer is very complete, I prefer editing the command history.

In normal mode, type: q:. This will give you a list of recent commands, editable and searchable with normal vim commands. You'll start on a blank command line at the bottom.

For the exact thing that the article asks, pasting a yanked line (or yanked anything) into a command line, yank your text and then: q:p (get into command history edit mode, and then (p)ut your yanked text into a new command line. Edit at will, enter to execute.

To get out of command history mode, it's the opposite. In normal mode in command history, type: :q + enter

You can use QString.arg like this

QString my_formatted_string = QString("%1/%2-%3.txt").arg("~", "Tom", "Jane");
// You get "~/Tom-Jane.txt"

This method is preferred over sprintf because:

Changing the position of the string without having to change the ordering of substitution, e.g.

// To get "~/Jane-Tom.txt"
QString my_formatted_string = QString("%1/%3-%2.txt").arg("~", "Tom", "Jane");

Or, changing the type of the arguments doesn't require changing the format string, e.g.

// To get "~/Tom-1.txt"
QString my_formatted_string = QString("%1/%2-%3.txt").arg("~", "Tom", QString::number(1));

As you can see, the change is minimal. Of course, you generally do not need to care about the type that is passed into QString::arg() since most types are correctly overloaded.

One drawback though: QString::arg() doesn't handle std::string. You will need to call: QString::fromStdString() on your std::string to make it into a QString before passing it to QString::arg(). Try to separate the classes that use QString from the classes that use std::string. Or if you can, switch to QString altogether.

UPDATE: Examples are updated thanks to alexisdm.

Using a custom url attribute makes the HTML invalid. Although that may not be a huge problem, the given examples are neither accessible. Not for keyboard navigation and not in cases when JavaScript is turned off (or blocked by some other script). Even Google will not find the page located at the specified url, not via this route at least.

It's quite easy to make this accessible though. Just make sure there's a regular link inside the div that points to the url. Using JavaScript/jQuery you add an onclick to the div that redirects to the location specified by the link's href attribute. Now, when JavaScript doesn't work, the link still does and it can even catch the focus when using the keyboard to navigate (and you don't need custom attributes, so your HTML can be valid).

I wrote a jQuery plugin some time ago that does this. It also adds classNames to the div (or any other element you want to make clickable) and the link so you can alter their looks with CSS when the div is indeed clickable. It even adds classNames that you can use to specify hover and focus styles.

All you need to do is specify the element(s) you want to make clickable and call their clickable() method: in your case that would be $("div.clickable).clickable();

For downloading + documentation see the plugin's page: jQuery: clickable — jLix

In regards Jared's response, having Windows 2000 or better will not necessarily fix the issue at hand. Rob's response does work, however it is possible that this fix introduces security issues, as Windows updates will not be able to patch applications built as such.

In another post, Nick Guerrera suggests packaging the Visual C++ Runtime Redistributable with your applications, which installs quickly, and is independent of Visual Studio.

Concrete example

mosquitto.org is very active (at the time of this posting). This is a nice smoke test for a MQTT subscriber linux device:

mosquitto_sub -h test.mosquitto.org -t "#" -v

The "#" is a wildcard for topics and returns all messages (topics): the server had a lot of traffic, so it returned a 'firehose' of messages.

If your MQTT device publishes a topic of irisys/V4D-19230005/ to the test MQTT broker , then you could filter the messages:

mosquitto_sub -h test.mosquitto.org -t "irisys/V4D-19230005/#" -v

Options:

• -h the hostname (default MQTT port = 1883)
• -t precedes the topic

How about :

SQL> select * from all_users;

it will return list of all users/schemas, their ID's and date created in DB :

USERNAME                          USER_ID CREATED
------------------------------ ---------- ---------
SCHEMA1                         120 09-SEP-15
SCHEMA2                         119 09-SEP-15
SCHEMA3                         118 09-SEP-15

System.getProperty("java.class.path")

If you want to delete all files whose names match a particular form, a wildcard (glob pattern) is the most straightforward solution. Some examples:

$ rm -f abc.log.*             # Remove them all
$ rm -f abc.log.2012*         # Remove all logs from 2012
$ rm -f abc.log.2012-0[123]*  # Remove all files from the first quarter of 2012

Regular expressions are more powerful than wildcards; you can feed the output of grep to rm -f. For example, if some of the file names start with "abc.log" and some with "ABC.log", grep lets you do a case-insensitive match:

$ rm -f $(ls | grep -i '^abc\.log\.')

This will cause problems if any of the file names contain funny characters, including spaces. Be careful.

When I do this, I run the ls | grep ... command first and check that it produces the output I want -- especially if I'm using rm -f:

$ ls | grep -i '^abc\.log\.'
(check that the list is correct)
$ rm -f $(!!)

where !! expands to the previous command. Or I can type up-arrow or Ctrl-P and edit the previous line to add the rm -f command.

This assumes you're using the bash shell. Some other shells, particularly csh and tcsh and some older sh-derived shells, may not support the $(...) syntax. You can use the equivalent backtick syntax:

$ rm -f `ls | grep -i '^abc\.log\.'`

The $(...) syntax is easier to read, and if you're really ambitious it can be nested.

Finally, if the subset of files you want to delete can't be easily expressed with a regular expression, a trick I often use is to list the files to a temporary text file, then edit it:

$ ls > list
$ vi list   # Use your favorite text editor

I can then edit the list file manually, leaving only the files I want to remove, and then:

$ rm -f $(<list)

or

$ rm -f `cat list`

(Again, this assumes none of the file names contain funny characters, particularly spaces.)

Or, when editing the list file, I can add rm -f to the beginning of each line and then:

$ . ./list

or

$ source ./list

Editing the file is also an opportunity to add quotes where necessary, for example changing rm -f foo bar to rm -f 'foo bar' .

This problem can occur if you have altogether too much stuff being started when the server is started -- or if you are in debug mode and stepping through the initialization sequence. In eclipse, changing the start-timeout by 'opening' the tomcat server entry 'Servers view' tab of the Debug Perspective is convenient. In some situations it is useful to know where this setting is 'really' stored.

Tomcat reads this setting from the element in the element in the servers.xml file. This file is stored in the .metatdata/.plugins/org.eclipse.wst.server.core directory of your eclipse workspace, ie:

//.metadata/.plugins/org.eclipse.wst.server.core/servers.xml

There are other juicy configuration files for Eclipse plugins in other directories under .metadata/.plugins as well.

Here's an example of the servers.xml file, which is what is changed when you edit the tomcat server configuration through the Eclipse GUI:

Note the 'start-timeout' property that is set to a good long 1200 seconds above.

You can call native methods trough trigger in jQuery. Just do this:

$('.play').trigger("play");

And the same for pause: $('.play').trigger("pause");

EDIT: as F... pointed out in the comments, you can do something similar to access properties: $('.play').prop("paused");

Complementing YvesgereY's great answer, I found this visualization extremely helpful:

Padding 'valid' is the first figure. The filter window stays inside the image.

Padding 'same' is the third figure. The output is the same size.

It's easy, you should set server http response header first. The problem is not with your front-end javascript code. You need to return this header:

Access-Control-Allow-Origin:*

or

Access-Control-Allow-Origin:your domain

In Apache config files, the code is like this:

Header set Access-Control-Allow-Origin "*"

In nodejs,the code is like this:

res.setHeader('Access-Control-Allow-Origin','*');

1. I had to specify a port in the SQL Configuration manager > TCP/IP
2. Open the port on your firewall
3. Then connect remotely using: "server name\other database instance,(port number)"
4. Connected!

Please

1. locate the file [XAMPP Installation Directory]\php\php.ini (e.g. C:\xampp\php\php.ini)
2. open php.ini in Notepad or any Text editor
3. locate the line containing max_execution_time and
4. increase the value from 30 to some larger number (e.g. set: max_execution_time = 90)
5. then restart Apache web server from the XAMPP control panel

If there will still be the same error after that, try to increase the value for the max_execution_time further more.

I don't think the issue is really about Django scaling.

I really suggest you look into your architecture that's what will help you with your scaling needs.If you get that wrong there is no point on how well Django performs. Performance != Scale. You can have a system that has amazing performance but does not scale and vice versa.

Is your application database bound? If it is then your scale issues lay there as well. How are you planning on interacting with the database from Django? What happens when you database cannot process requests as fast as Django accepts them? What happens when your data outgrows one physical machine. You need to account for how you plan on dealing with those circumstances.

Moreover, What happens when your traffic outgrows one app server? how you handle sessions in this case can be tricky, more often than not you would probably require a shared nothing architecture. Again that depends on your application.

In short languages is not what determines scale, a language is responsible for performance(again depending on your applications, different languages perform differently). It is your design and architecture that makes scaling a reality.

I hope it helps, would be glad to help further if you have questions.

remember versions 5.7.23 and up - the user table doesn't has column password instead authentication string so below works while resetting password for a user.

update user set authentication_string=password('root') where user='root';

This is a highly inefficient way of doing it. You can use the merge statement and then there's no need for cursors, looping or (if you can do without) PL/SQL.

MERGE INTO studLoad l
USING ( SELECT studId, studName FROM student ) s
ON (l.studId = s.studId)
WHEN MATCHED THEN
  UPDATE SET l.studName = s.studName
   WHERE l.studName != s.studName
WHEN NOT MATCHED THEN 
INSERT (l.studID, l.studName)
VALUES (s.studId, s.studName)

Make sure you commit, once completed, in order to be able to see this in the database.

To actually answer your question I would do it something like as follows. This has the benefit of doing most of the work in SQL and only updating based on the rowid, a unique address in the table.

It declares a type, which you place the data within in bulk, 10,000 rows at a time. Then processes these rows individually.

However, as I say this will not be as efficient as merge.

declare

   cursor c_data is
    select b.rowid as rid, a.studId, a.studName
      from student a
      left outer join studLoad b
        on a.studId = b.studId
       and a.studName <> b.studName
           ;

   type t__data is table of c_data%rowtype index by binary_integer;
   t_data t__data;

begin

   open c_data;
   loop
      fetch c_data bulk collect into t_data limit 10000;

      exit when t_data.count = 0;

      for idx in t_data.first .. t_data.last loop
         if t_data(idx).rid is null then
            insert into studLoad (studId, studName)
            values (t_data(idx).studId, t_data(idx).studName);
         else
            update studLoad
               set studName = t_data(idx).studName
             where rowid = t_data(idx).rid
                   ;
         end if;
      end loop;

   end loop;
   close c_data;

end;
/

If you want to open it for a range and for a protocol

ufw allow 11200:11299/tcp
ufw allow 11200:11299/udp

You can just do a cast

int val1 = 1;
float val2 = (float)val1;

or

decimal val3 = 3;
float val4 = (float)val3;

You can raise a notice in Postgres as follows:

raise notice 'Value: %', deletedContactId;

You can write in a file by the following code example:

var data = [{ 'test': '123', 'test2': 'Lorem Ipsem ' }];
fs.open(datapath + '/data/topplayers.json', 'wx', function (error, fileDescriptor) {
  if (!error && fileDescriptor) {
    var stringData = JSON.stringify(data);
    fs.writeFile(fileDescriptor, stringData, function (error) {
      if (!error) {
        fs.close(fileDescriptor, function (error) {
          if (!error) {
            callback(false);
          } else {
            callback('Error in close file');
          }
        });
      } else {
        callback('Error in writing file.');
      }
    });
  }
});

In Python 2:

>>> "7061756c".decode("hex")
'paul'

In Python 3:

>>> bytes.fromhex('7061756c').decode('utf-8')
'paul'

I ran into the same issue, but then did the following, and my issue was resolved:

• updated Gradle
• installed the latest version of Android studio (mine was out of date)

And that solved my problem.

Note: It also helped me to click on the event log, because it has more detailed info about errors. https://developer.android.com/studio/releases/gradle-plugin#updating-plugin also has great info.

The only standard mandated implementation dependent way is to use the system() function from stdlib.h.

Also if you know how to make user become the super-user that would be nice also.

Do you want the script to run as super-user or do you want to elevate the privileges of the C executable? The former can be done with sudo but there are a few things you need to know before you can go off using sudo.

  kw=(EditText)findViewById(R.id.kw);
    btn=(Button)findViewById(R.id.btn);
    cost=(TextView )findViewById(R.id.cost);


            btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) { cst =  Double.valueOf(kw.getText().toString());
            cst = cst*0.551;
            cost.setText(cst.toString());
        }
    });

This one deserves an update - nowadays we have the wheel event :

$(function() {_x000D_
_x000D_
$(window).on('wheel', function(e) {_x000D_
_x000D_
 var delta = e.originalEvent.deltaY;_x000D_
_x000D_
 if (delta > 0) $('body').text('down');_x000D_
 else $('body').text('up');_x000D_
_x000D_
 return false; // this line is only added so the whole page won't scroll in the demo_x000D_
});_x000D_
});

body {_x000D_
  font-size: 22px;_x000D_
  text-align: center;_x000D_

  background: grey;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Support has been pretty good on modern browsers for quite a while already :

• Chrome 31+
• Firefox 17+
• IE9+
• Opera 18+
• Safari 7+

https://developer.mozilla.org/en-US/docs/Web/Events/wheel

If deeper browser support is required, probably best to use mousewheel.js instead of messing about :

https://plugins.jquery.com/mousewheel/

$(function() {_x000D_
_x000D_
$(window).mousewheel(function(turn, delta) {_x000D_
_x000D_
 if (delta > 0) $('body').text('up');_x000D_
 else $('body').text('down');_x000D_

I am on Xcode 8.3.2. For me the issue was the AppleWWDRCA certificate was in both system and login keychain. Removed both and then added to just login keychain, now it runs fine again. 2 days lost

Other languages such as PHP accept a parameter for break (i.e. break 2;) to specify the amount of nested loop levels you want to break out of, C++ however doesn't. You will have to work it out by using a boolean that you set to false prior to the loop, set to true in the loop if you want to break, plus a conditional break after the nested loop, checking if the boolean was set to true and break if yes.

You could copy and paste an answer here, or you could go read what our host Joel has to say about strcat.

All these answers are correct, but I had to also check if the string contains other characters and Hebrew letters so I simply used:

if (!str.match(/^[\d]+$/)) {
    //contains other characters as well
}

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.Table;

@Entity
@Table(name="empTable")
public class Employee implements Serializable{
private static final long serialVersionUID = 1L;
private int id;
private String empName;

List<Address> addList=new ArrayList<Address>();


@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name="emp_id")
public int getId() {
    return id;
}
public void setId(int id) {
    this.id = id;
}
public String getEmpName() {
    return empName;
}
public void setEmpName(String empName) {
    this.empName = empName;
}

@OneToMany(mappedBy="employee",cascade=CascadeType.ALL)
public List<Address> getAddList() {
    return addList;
}

public void setAddList(List<Address> addList) {
    this.addList = addList;
}
}

We have two entities Employee and Address with One to Many relationship.

import java.io.Serializable;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.Table;

@Entity
@Table(name="address")
public class Address implements Serializable{

private static final long serialVersionUID = 1L;

private int address_id;
private String address;
Employee employee;

@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
public int getAddress_id() {
    return address_id;
}
public void setAddress_id(int address_id) {
    this.address_id = address_id;
}
public String getAddress() {
    return address;
}
public void setAddress(String address) {
    this.address = address;
}

@ManyToOne
@JoinColumn(name="emp_id")
public Employee getEmployee() {
    return employee;
}
public void setEmployee(Employee employee) {
    this.employee = employee;
}
}

By this way we can implement inner join between two tables

import java.util.List;
import org.hibernate.Query;
import org.hibernate.Session;

public class Main {

public static void main(String[] args) {
    saveEmployee();

    retrieveEmployee();

}

private static void saveEmployee() {
    Employee employee=new Employee();
    Employee employee1=new Employee();
    Employee employee2=new Employee();
    Employee employee3=new Employee();

    Address address=new Address();
    Address address1=new Address();
    Address address2=new Address();
    Address address3=new Address();

    address.setAddress("1485,Sector 42 b");
    address1.setAddress("1485,Sector 42 c");
    address2.setAddress("1485,Sector 42 d");
    address3.setAddress("1485,Sector 42 a");

    employee.setEmpName("Varun");
    employee1.setEmpName("Krishan");
    employee2.setEmpName("Aasif");
    employee3.setEmpName("Dut");

    address.setEmployee(employee);
    address1.setEmployee(employee1);
    address2.setEmployee(employee2);
    address3.setEmployee(employee3);

    employee.getAddList().add(address);
    employee1.getAddList().add(address1);
    employee2.getAddList().add(address2);
    employee3.getAddList().add(address3);

    Session session=HibernateUtil.getSessionFactory().openSession();

    session.beginTransaction();

    session.save(employee);
    session.save(employee1);
    session.save(employee2);
    session.save(employee3);
    session.getTransaction().commit();
    session.close();
}

private static void retrieveEmployee() {
    try{

    String sqlQuery="select e from Employee e inner join e.addList";

    Session session=HibernateUtil.getSessionFactory().openSession();

    Query query=session.createQuery(sqlQuery);

    List<Employee> list=query.list();

     list.stream().forEach((p)->{System.out.println(p.getEmpName());});     
    session.close();
    }catch(Exception e){
        e.printStackTrace();
    }
}
}

I have used Java 8 for loop for priting the names. Make sure you have jdk 1.8 with tomcat 8. Also add some more records for better understanding.

 public class HibernateUtil {
 private static SessionFactory sessionFactory ;
 static {
    Configuration configuration = new Configuration();

    configuration.addAnnotatedClass(Employee.class);
    configuration.addAnnotatedClass(Address.class);
                  configuration.setProperty("connection.driver_class","com.mysql.jdbc.Driver");
    configuration.setProperty("hibernate.connection.url", "jdbc:mysql://localhost:3306/hibernate");                                
    configuration.setProperty("hibernate.connection.username", "root");     
    configuration.setProperty("hibernate.connection.password", "root");
    configuration.setProperty("dialect", "org.hibernate.dialect.MySQLDialect");
    configuration.setProperty("hibernate.hbm2ddl.auto", "update");
    configuration.setProperty("hibernate.show_sql", "true");
    configuration.setProperty(" hibernate.connection.pool_size", "10");


   // configuration
    StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
    sessionFactory = configuration.buildSessionFactory(builder.build());
 }
public static SessionFactory getSessionFactory() {
    return sessionFactory;
}
} 

var path = window.location.pathname;
var page = path.split("/").pop();
console.log( page );

Use implementation androidx.appcompat:appcompat:1.0.2 in gradle and then

change import android.support.annotation.Nullable; to import androidx.annotation.NonNull; in the classes imports

You can also use the new HTML5 custom data- attributes.

<script type="text/javascript">
$(document).ready(function() {
    $('.my_button').click(function() {
        alert($(this).attr('data-value'));
    });
});
</script>

<button class="my_button" name="buttonName" data-value="buttonValue">Button Label</button>

This counts the rows of the inner query:

select count(*) from (
    select count(SID) 
    from Test 
    where Date = '2012-12-10' 
    group by SID
) t

However, in this case the effect of that is the same as this:

select count(distinct SID) from Test where Date = '2012-12-10'

1) @RequestParam is used to extract query parameters

http://localhost:3000/api/group/test?id=4

@GetMapping("/group/test")
public ResponseEntity<?> test(@RequestParam Long id) {
    System.out.println("This is test");
    return ResponseEntity.ok().body(id);
}

while @PathVariable is used to extract data right from the URI:

http://localhost:3000/api/group/test/4

@GetMapping("/group/test/{id}")
public ResponseEntity<?> test(@PathVariable Long id) {
    System.out.println("This is test");
    return ResponseEntity.ok().body(id);
}

2) @RequestParam is more useful on a traditional web application where data is mostly passed in the query parameters while @PathVariable is more suitable for RESTful web services where URL contains values.

3) @RequestParam annotation can specify default values if a query parameter is not present or empty by using a defaultValue attribute, provided the required attribute is false:

@RestController
@RequestMapping("/home")
public class IndexController {

    @RequestMapping(value = "/name")
    String getName(@RequestParam(value = "person", defaultValue = "John") String personName) {
        return "Required element of request param";
    }

}

With the WebClient class:

using System.Net;
//...
WebClient Client = new WebClient ();
Client.DownloadFile("http://i.stackoverflow.com/Content/Img/stackoverflow-logo-250.png", @"C:\folder\stackoverflowlogo.png");

While the basic difference is that & is used for bitwise operations mostly on long, int or byte where it can be used for kind of a mask, the results can differ even if you use it instead of logical &&.

The difference is more noticeable in some scenarios:

1. Evaluating some of the expressions is time consuming
2. Evaluating one of the expression can be done only if the previous one was true
3. The expressions have some side-effect (intended or not)

First point is quite straightforward, it causes no bugs, but it takes more time. If you have several different checks in one conditional statements, put those that are either cheaper or more likely to fail to the left.

For second point, see this example:

if ((a != null) & (a.isEmpty()))

This fails for null, as evaluating the second expression produces a NullPointerException. Logical operator && is lazy, if left operand is false, the result is false no matter what right operand is.

Example for the third point -- let's say we have an app that uses DB without any triggers or cascades. Before we remove a Building object, we must change a Department object's building to another one. Let's also say the operation status is returned as a boolean (true = success). Then:

if (departmentDao.update(department, newBuilding) & buildingDao.remove(building))

This evaluates both expressions and thus performs building removal even if the department update failed for some reason. With &&, it works as intended and it stops after first failure.

As for a || b, it is equivalent of !(!a && !b), it stops if a is true, no more explanation needed.

I would recommend doing it like this to keep things in line with HTML5.

<meta charset="UTF-8">

EG:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
</head>
<body>
</body>
</html>

I had the same issue I have resolved by adding a media query for @screen-xs-min in less version under Modals.less

@media (max-width: @screen-xs-min) {
  .modal-xs { width: @modal-sm; }
}

Use the title attribute while alt is important for SEO stuff.

Spring JPA DAO

For example we have some entity Group.

For this entity we create the repository GroupRepository.

public interface GroupRepository extends JpaRepository<Group, Long> {   
}

Then we need to create a service layer with which we will use this repository.

public interface Service<T, ID> {

    T save(T entity);

    void deleteById(ID id);

    List<T> findAll();

    T getOne(ID id);

    T editEntity(T entity);

    Optional<T> findById(ID id);
}

public abstract class AbstractService<T, ID, R extends JpaRepository<T, ID>> implements Service<T, ID> {

    private final R repository;

    protected AbstractService(R repository) {
        this.repository = repository;
    }

    @Override
    public T save(T entity) {
        return repository.save(entity);
    }

    @Override
    public void deleteById(ID id) {
        repository.deleteById(id);
    }

    @Override
    public List<T> findAll() {
        return repository.findAll();
    }

    @Override
    public T getOne(ID id) {
        return repository.getOne(id);
    }

    @Override
    public Optional<T> findById(ID id) {
        return repository.findById(id);
    }

    @Override
    public T editEntity(T entity) {
        return repository.saveAndFlush(entity);
    }
}

@org.springframework.stereotype.Service
public class GroupServiceImpl extends AbstractService<Group, Long, GroupRepository> {

    private final GroupRepository groupRepository;

    @Autowired
    protected GroupServiceImpl(GroupRepository repository) {
        super(repository);
        this.groupRepository = repository;
    }
}

And in the controller we use this service.

@RestController
@RequestMapping("/api")
class GroupController {

    private final Logger log = LoggerFactory.getLogger(GroupController.class);

    private final GroupServiceImpl groupService;

    @Autowired
    public GroupController(GroupServiceImpl groupService) {
        this.groupService = groupService;
    }

    @GetMapping("/groups")
    Collection<Group> groups() {
        return groupService.findAll();
    }

    @GetMapping("/group/{id}")
    ResponseEntity<?> getGroup(@PathVariable Long id) {
        Optional<Group> group = groupService.findById(id);
        return group.map(response -> ResponseEntity.ok().body(response))
                .orElse(new ResponseEntity<>(HttpStatus.NOT_FOUND));
    }

    @PostMapping("/group")
    ResponseEntity<Group> createGroup(@Valid @RequestBody Group group) throws URISyntaxException {
        log.info("Request to create group: {}", group);
        Group result = groupService.save(group);
        return ResponseEntity.created(new URI("/api/group/" + result.getId()))
                .body(result);
    }

    @PutMapping("/group")
    ResponseEntity<Group> updateGroup(@Valid @RequestBody Group group) {
        log.info("Request to update group: {}", group);
        Group result = groupService.save(group);
        return ResponseEntity.ok().body(result);
    }

    @DeleteMapping("/group/{id}")
    public ResponseEntity<?> deleteGroup(@PathVariable Long id) {
        log.info("Request to delete group: {}", id);
        groupService.deleteById(id);
        return ResponseEntity.ok().build();
    }    
}

Referencing means taking the address of an existing variable (using &) to set a pointer variable. In order to be valid, a pointer has to be set to the address of a variable of the same type as the pointer, without the asterisk:

int  c1;
int* p1;
c1 = 5;
p1 = &c1;
//p1 references c1

Dereferencing a pointer means using the * operator (asterisk character) to retrieve the value from the memory address that is pointed by the pointer: NOTE: The value stored at the address of the pointer must be a value OF THE SAME TYPE as the type of variable the pointer "points" to, but there is no guarantee this is the case unless the pointer was set correctly. The type of variable the pointer points to is the type less the outermost asterisk.

int n1;
n1 = *p1;

Invalid dereferencing may or may not cause crashes:

• Dereferencing an uninitialized pointer can cause a crash
• Dereferencing with an invalid type cast will have the potential to cause a crash.
• Dereferencing a pointer to a variable that was dynamically allocated and was subsequently de-allocated can cause a crash
• Dereferencing a pointer to a variable that has since gone out of scope can also cause a crash.

Invalid referencing is more likely to cause compiler errors than crashes, but it's not a good idea to rely on the compiler for this.

The following will update all rows in one table

Update Table Set
Column1 = 'New Value'

The next one will update all rows where the value of Column2 is more than 5

Update Table Set
Column1 = 'New Value'
Where
Column2 > 5

There is all Unkwntech's example of updating more than one table

UPDATE table1, table2 SET
table1.col1 = 'value',
table2.col1 = 'value'
WHERE
table1.col3 = '567'
AND table2.col6='567'

Well you could either initialize the xib using a view controller and use viewController.view. or do it the way you did it. Only making a UIView subclass as the controller for UIView is a bad idea.

If you don't have any outlets from your custom view then you can directly use a UIViewController class to initialize it.

Update: In your case:

UIViewController *genericViewCon = [[UIViewController alloc] initWithNibName:@"CustomView"];
//Assuming you have a reference for the activity indicator in your custom view class
CustomView *myView = (CustomView *)genericViewCon.view;
[parentView addSubview:myView];
//And when necessary
[myView.activityIndicator startAnimating]; //or stop

Otherwise you have to make a custom UIViewController(to make it as the file's owner so that the outlets are properly wired up).

YourCustomController *yCustCon = [[YourCustomController alloc] initWithNibName:@"YourXibName"].

Wherever you want to add the view you can use.

[parentView addSubview:yCustCon.view];

However passing the another view controller(already being used for another view) as the owner while loading the xib is not a good idea as the view property of the controller will be changed and when you want to access the original view, you won't have a reference to it.

EDIT: You will face this problem if you have setup your new xib with file's owner as the same main UIViewController class and tied the view property to the new xib view.

i.e;

• YourMainViewController -- manages -- mainView
• CustomView -- needs to load from xib as and when required.

The below code will cause confusion later on, if you write it inside view did load of YourMainViewController. That is because self.view from this point on will refer to your customview

-(void)viewDidLoad:(){
  UIView *childView= [[[NSBundle mainBundle] loadNibNamed:@"YourXibName" owner:self options:nil] objectAtIndex:0];
}

If you have context data along with css and js in your html template. Than you have good option to use pdfjs.

In your code you can use like this.

from django.template.loader import get_template
import pdfkit
from django.conf import settings

context={....}
template = get_template('reports/products.html')
html_string = template.render(context)
pdfkit.from_string(html_string, os.path.join(settings.BASE_DIR, "media", 'products_report-%s.pdf'%(id)))

In your HTML you can link extranal or internal css and js, it will generate best quality of pdf.

That code gets you the IP address of your server not the address of the client who is accessing your website. Use the HttpContext.Current.Request.UserHostAddress property to the client's IP address.

Each row has an ID. All you have to do is to send this ID to the function setSelected(), store it (in $scope.idSelectedVote for instance), and then check for each row if the selected ID is the same as the current one. Here is a solution (see the documentation for ngClass, if needed):

$scope.idSelectedVote = null;
$scope.setSelected = function (idSelectedVote) {
   $scope.idSelectedVote = idSelectedVote;
};

<ul ng-repeat="vote in votes" ng-click="setSelected(vote.id)" ng-class="{selected: vote.id === idSelectedVote}">
    ...
</ul>

If you're using profilers like AQ Time, these may also be locking the file. The solution in this case would be to restart the profiler or simply unload/load the assembly in question from the profiler. For AQ Time I noticed that it's releasing the file after some time, but I can't for the life of me tell what that timeout is. Seems to be random

1. It is recommend to use List to deal with small scale size.

2. If you have a huge number of numbers, NEVER use List and autoboxing,

   List< Integer> list

For every single int, a new Integer is auto created. You will find it getting slow when the size of the list increase. These Integers are unnecessary objects. In this case, to use a estimated size would be better,

int[] array = new int[ESTIMATED_SIZE];

If you have a rogue loop, pause the code in Google Chrome debugger (the small "||" button while in Sources tab).

Switch back to Chrome itself, open "Task Manager" (Shift+ESC), select your tab, click the "End Process" button.

You will get the Aww Snap message and then you can reload (F5).

As others have noted, reloading the page at the point of pausing is the same as restarting the rogue loop and can cause nasty lockups if the debugger also then locks (in some cases leading to restarting chrome or even the PC). The debugger needs a "Stop" button. Nb: The accepted answer is out of date in that some aspects of it are now apparently wrong. If you vote me down, pls explain :).

I faced the same problem.

Just removed the server from configuration and added it back after restarting eclipse by adding it to the server runtime environment.

There is package modeest which provide estimators of the mode of univariate unimodal (and sometimes multimodal) data and values of the modes of usual probability distributions.

mySamples <- c(19, 4, 5, 7, 29, 19, 29, 13, 25, 19)

library(modeest)
mlv(mySamples, method = "mfv")

Mode (most likely value): 19 
Bickel's modal skewness: -0.1 
Call: mlv.default(x = mySamples, method = "mfv")

If you don't find the proper SDK path then, 1. Open Android Stidio 2. Go to Tools 3. Go to SDK Manager 4. You will find the "Android SDK Location"

Copy the path and edit the "Environment Variable" After it, restart and run the cmd. Then, run "flutter doctor" Hope, it will Work!

Your query translates to:

SELECT name FROM users WHERE id IN ('Array');

Or something to that affect.

Try using prepared queries instead, something like:

$numbers = explode(',', $string);
$prepare = array_map(function(){ return '?'; }, $numbers);
$statement = mysqli_prepare($link , "SELECT name FROM users WHERE id IN ('".implode(',', $prepare)."')");
if($statement) {
   $ints = array_map(function(){ return 'i'; }, $numbers);
   call_user_func_array("mysqli_stmt_bind_param", array_merge(
      array($statement, implode('', $ints)), $numbers
   ));
   $results = mysqli_stmt_execute($statement);
   // do something with results 
   // ...
}

When I downloaded chromedriver.exe I just move it in PATH folder C:\Windows\System32\chromedriver.exe and had exact same problem.

For me solution was to just change folder in PATH, so I just moved it at Pycharm Community bin folder that was also in PATH. ex:

• C:\Windows\System32\chromedriver.exe --> Gave me exception
• C:\Program Files\JetBrains\PyCharm Community Edition 2019.1.3\bin\chromedriver.exe --> worked fine

Generally you cannot translate from a time zone like Asia/Kolkata to a GMT offset like +05:30 or +07:00. A time zone, as the name says, is a place on earth and comprises the historic, present and known future UTC offsets used by the people in that place (for now we can regard GMT and UTC as synonyms, strictly speaking they are not). For example, Asia/Kolkata has been at offset +05:30 since 1945. During periods between 1941 and 1945 it was at +06:30 and before that time at +05:53:20 (yes, with seconds precision). Many other time zones have summer time (daylight saving time, DST) and change their offset twice a year.

Given a point in time, we can make the translation for that particular point in time, though. I should like to provide the modern way of doing that.

java.time and ThreeTenABP

    ZoneId zone = ZoneId.of("Asia/Kolkata");

    ZoneOffset offsetIn1944 = LocalDateTime.of(1944, Month.JANUARY, 1, 0, 0)
            .atZone(zone)
            .getOffset();
    System.out.println("Offset in 1944: " + offsetIn1944);

    ZoneOffset offsetToday = OffsetDateTime.now(zone)
            .getOffset();
    System.out.println("Offset now: " + offsetToday);

Output when running just now was:

Offset in 1944: +06:30
Offset now: +05:30

For the default time zone set zone to ZoneId.systemDefault().

To format the offset with the text GMT use a formatter with OOOO (four uppercase letter O) in the pattern:

    DateTimeFormatter offsetFormatter = DateTimeFormatter.ofPattern("OOOO");
    System.out.println(offsetFormatter.format(offsetToday));

GMT+05:30

I am recommending and in my code I am using java.time, the modern Java date and time API. The TimeZone, Calendar, Date, SimpleDateFormat and DateFormat classes used in many of the other answers are poorly designed and now long outdated, so my suggestion is to avoid all of them.

Question: Can I use java.time on Android?

Yes, java.time works nicely on older and newer Android devices. It just requires at least Java 6.

• In Java 8 and later and on newer Android devices (from API level 26) the modern API comes built-in.
• In Java 6 and 7 get the ThreeTen Backport, the backport of the modern classes (ThreeTen for JSR 310; see the links at the bottom).
• On (older) Android use the Android edition of ThreeTen Backport. It’s called ThreeTenABP. And make sure you import the date and time classes from org.threeten.bp with subpackages.

Add the library from File->Right click->New->Module->Import Eclipse ADT project->brows your library->finish Now add in the app gradle setting following code:

implementation project(':library')

Finally add in the setting gradle following code:

include ':app', ':library'

As found on the mailing list archive,

• http://osdir.com/ml/gnu.make.windows/2004-03/msg00063.html
• http://osdir.com/ml/gnu.make.general/2005-10/msg00064.html

one can use the filter function.

For example

ifeq ($(GCC_MINOR),$(filter $(GCC_MINOR),4 5))

filter X, A B will return those of A,B that are equal to X. Note, while this is not relevant in the above example, this is a XOR operation. I.e. if you instead have something like:

ifeq (4, $(filter 4, $(VAR1) $(VAR2)))

And then do e.g. make VAR1=4 VAR2=4, the filter will return 4 4, which is not equal to 4.

A variation that performs an OR operation instead is:

ifneq (,$(filter $(GCC_MINOR),4 5))

where a negative comparison against an empty string is used instead (filter will return en empty string if GCC_MINOR doesn't match the arguments). Using the VAR1/VAR2 example it would look like this:

ifneq (, $(filter 4, $(VAR1) $(VAR2)))

The downside to those methods is that you have to be sure that these arguments will always be single words. For example, if VAR1 is 4 foo, the filter result is still 4, and the ifneq expression is still true. If VAR1 is 4 5, the filter result is 4 5 and the ifneq expression is true.

One easy alternative is to just put the same operation in both the ifeq and else ifeq branch, e.g. like this:

ifeq ($(GCC_MINOR),4)
    @echo Supported version
else ifeq ($(GCC_MINOR),5)
    @echo Supported version
else
    @echo Unsupported version
endif

Great Answer by Jon.

I'm lazy though and I hate typing, so I created a simple cut and paste example for all the other people who are like me. Enjoy!

import java.util.ArrayList;
import java.util.List;

public class Main {

    public static void main(String[] args) {

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

        animals.add("Lion");
        animals.add("Tiger");
        animals.add("Cat");
        animals.add("Dog");

        System.out.println(animals); // [Lion, Tiger, Cat, Dog]

        // add() -> push(): Add items to the end of an array
        animals.add("Elephant");
        System.out.println(animals);  // [Lion, Tiger, Cat, Dog, Elephant]

        // remove() -> pop(): Remove an item from the end of an array
        animals.remove(animals.size() - 1);
        System.out.println(animals); // [Lion, Tiger, Cat, Dog]

        // add(0,"xyz") -> unshift(): Add items to the beginning of an array
        animals.add(0, "Penguin");
        System.out.println(animals); // [Penguin, Lion, Tiger, Cat, Dog]

        // remove(0) -> shift(): Remove an item from the beginning of an array
        animals.remove(0);
        System.out.println(animals); // [Lion, Tiger, Cat, Dog]

    }

}

One other significant point if you're using C# 6:

'=>' can be used instead of 'get' and is only for 'get only' methods - it can't be used with a 'set'.

For C# 7, see the comment from @avenmore below - it can now be used in more places. Here's a good reference - https://csharp.christiannagel.com/2017/01/25/expressionbodiedmembers/

If you need to log an error to Apache error log you can try this:

error_log( print_r($multidimensionalarray, TRUE) );

Output the images in a lossless format such as PNG:

ffmpeg.exe -i 10fps.h264 -r 10 -f image2 10fps.h264_%03d.png

Edit/Update: Not quite sure why I originally gave a strange filename example (with a possibly made-up extension).

I have since found that -vsync 0 is simpler than -r 10 because it avoids needing to know the frame rate.

This is something like what I currently use:

mkdir stills
ffmpeg -i my-film.mp4 -vsync 0 -f image2 stills/my-film-%06d.png

To extract only the key frames (which are likely to be of higher quality post-edit):

ffmpeg -skip_frame nokey -i my-film.mp4 -vsync 0 -f image2 stills/my-film-%06d.png

Then use another program (where you can more precisely specify quality, subsampling and DCT method – e.g. GIMP) to convert the PNGs you want to JPEG.

It is possible to obtain slightly sharper images in JPEG format this way than is possible with -qmin 1 -q:v 1 and outputting as JPEG directly from ffmpeg.

Yes:

git rev-parse --show-toplevel

If you want to replicate the Git command more directly, you can create an alias:

git config --global alias.root 'rev-parse --show-toplevel'

and now git root will function just as hg root.

Note: In a submodule this will display the root directory of the submodule and not the parent repository. If you are using Git >=2.13 or above, there is a way that submodules can show the superproject's root directory. If your git is older than that, see this other answer.

You can use this option provided by dataTable itself using buttons.

dom: 'Bfrtip',
 buttons: [
      'selectAll',
      'selectNone'
 ]'

Here is a sample code

var tableFaculty = $('#tableFaculty').DataTable({
    "columns": [
        {
            data: function (row, type, set) {
                return '';
            }
        },
        {data: "NAME"}
    ],
    "columnDefs": [
        {
            orderable: false,
            className: 'select-checkbox',
            targets: 0
        }
    ],
    select: {
        style: 'multi',
        selector: 'td:first-child'
    },
    dom: 'Bfrtip',
    buttons: [
        'selectAll',
        'selectNone'
    ],
    "order": [[0, 'desc']]
});

package-lock.json is re-generated whenever you run npm i.

A couple of additional points re use of vector here.

Unlike ArrayList and Array in Java, you don't need to do anything special to treat a vector as an array - the underlying storage in C++ is guaranteed to be contiguous and efficiently indexable.

Unlike ArrayList, a vector can efficiently hold primitive types without encapsulation as a full-fledged object.

When removing items from a vector, be aware that the items above the removed item have to be moved down to preserve contiguous storage. This can get expensive for large containers.

Make sure if you store complex objects in the vector that their copy constructor and assignment operators are efficient. Under the covers, C++ STL uses these during container housekeeping.

Advice about reserve()ing storage upfront (ie. at vector construction or initialilzation time) to minimize memory reallocation on later extension carries over from Java to C++.

I have a simple Location class that I use to handle all of my marker-related things. I'll paste my code below for you to take a gander at.

The last line(s) is what actually creates the marker objects. It loops through some JSON of my locations, which look something like this:

{"locationID":"98","name":"Bergqvist Järn","note":null,"type":"retail","address":"Smidesvägen 3","zipcode":"69633","city":"Askersund","country":"Sverige","phone":"0583-120 35","fax":null,"email":null,"url":"www.bergqvist-jb.com","lat":"58.891079","lng":"14.917371","contact":null,"rating":"0","distance":"45.666885421019"}

Here is the code:

If you look at the target() method in my Location class, you'll see that I keep references to the infowindow's and can simply open() and close() them because of a reference.

See a live demo: http://ww1.arbesko.com/en/locator/ (type in a Swedish city, like stockholm, and hit enter)

var Location = function() {
    var self = this,
        args = arguments;

    self.init.apply(self, args);
};

Location.prototype = {
    init: function(location, map) {
        var self = this;

        for (f in location) { self[f] = location[f]; }

        self.map = map;

        // this is the marker point
        self.point = new google.maps.LatLng(parseFloat(self.lat), parseFloat(self.lng));
        locator.bounds.extend(self.point);

        // Create the marker for placement on the map
        self.marker = new google.maps.Marker({

The :: are used to dereference scopes.

const int x = 5;

namespace foo {
  const int x = 0;
}

int bar() {
  int x = 1;
  return x;
}

struct Meh {
  static const int x = 2;
}

int main() {
  std::cout << x; // => 5
  {
    int x = 4;
    std::cout << x; // => 4
    std::cout << ::x; // => 5, this one looks for x outside the current scope
  }
  std::cout << Meh::x; // => 2, use the definition of x inside the scope of Meh
  std::cout << foo::x; // => 0, use the definition of x inside foo
  std::cout << bar(); // => 1, use the definition of x inside bar (returned by bar)
}

unrelated: cout and cin are not functions, but instances of stream objects.

EDIT fixed as Keine Lust suggested

Here is my solution:

chrome.runtime.onMessage.addListener(function(request, sender) {
        if (request.action == "getSource") {
            this.pageSource = request.source;
            var title = this.pageSource.match(/<title[^>]*>([^<]+)<\/title>/)[1];
            alert(title)
        }
    });

    chrome.tabs.query({ active: true, currentWindow: true }, tabs => {
        chrome.tabs.executeScript(
            tabs[0].id,
            { code: 'var s = document.documentElement.outerHTML; chrome.runtime.sendMessage({action: "getSource", source: s});' }
        );
    });

Ensure you have an index on your firstname and lastname columns and go with 1. This really won't have much of a performance impact at all.

EDIT: After @Dems comment regarding spamming the plan cache ,a better solution might be to create a computed column on the existing table (or a separate view) which contained a concatenated Firstname + Lastname value, thus allowing you to execute a query such as

SELECT City 
FROM User 
WHERE Fullname in (@fullnames)

where @fullnames looks a bit like "'JonDoe', 'JaneDoe'" etc

This worked for me..

div.className {
display: inline-block;
margin: auto;
}

In WinForms and WebForms you can do:

txtName.BackColor = Color.Aqua;

If you want a really light weight (no dependencies, simple API, 15 kb jar file) and very fast solution, take a look at annotation-detector found at https://github.com/rmuller/infomas-asl

Disclaimer: I am the author.

We usually declare the constant as static. The reason for that is because Java creates copies of non static variables every time you instantiate an object of the class.

So if we make the constants static it would not do so and would save memory.

With final we can make the variable constant.

Hence the best practice to define a constant variable is the following:

private static final String YOUR_CONSTANT = "Some Value"; 

The access modifier can be private/public depending on the business logic.

The default display property for a table is display:table;. The only other useful value is inline-table. All other display values are invalid for table elements.

There isn't an auto option to reset it to default, although if you're working in Javascript, you can set it to an empty string, which will do the trick.

width:auto; is valid, but isn't the default. The default width for a table is 100%, whereas width:auto; will make the element only take up as much width as it needs to.

min-width:auto; isn't allowed. If you set min-width, it must have a value, but setting it to zero is probably as good as resetting it to default.

Try std::find

vector<int>::iterator it = std::find(v.begin(), v.end(), 123);

if(it==v.end()){

    std::cout<<"Element not found";
}

If your tiles are not in your bundle, either copied from the bundle or downloaded from the internet you can get the directory like this

NSString *documentdir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *tileDirectory = [documentdir stringByAppendingPathComponent:@"xxxx/Tiles"];
NSLog(@"Tile Directory: %@", tileDirectory);

[root]# cat time.c

#include <time.h>

int main(int argc, char** argv)
{
        time_t test;
        return 0;
}

[root]# gcc -E time.c | grep __time_t

typedef long int __time_t;

It's defined in $INCDIR/bits/types.h through:

# 131 "/usr/include/bits/types.h" 3 4
# 1 "/usr/include/bits/typesizes.h" 1 3 4
# 132 "/usr/include/bits/types.h" 2 3 4

Why you would want to do this is beyond me, since id is supposed to be unique in a document. However, browsers tend to be quite lax on this, so if you really must use getElementById for this purpose, you can do it like this:

function whywouldyoudothis() {
    var n = document.getElementById("non-unique-id");
    var a = [];
    var i;
    while(n) {
        a.push(n);
        n.id = "a-different-id";
        n = document.getElementById("non-unique-id");
    }

    for(i = 0;i < a.length; ++i) {
        a[i].id = "non-unique-id";      
    }
    return a;
}

However, this is silly, and I wouldn't trust this to work on all browsers forever. Although the HTML DOM spec defines id as readwrite, a validating browser will complain if faced with more than one element with the same id.

EDIT: Given a valid document, the same effect could be achieved thus:

function getElementsById(id) {
  return [document.getElementById(id)];
}

i used to do like this

inside view

<script type="text/javascript">

//will replace the '_transactionIds_' and '_payeeId_' 
var _addInvoiceUrl = '@(Html.Raw( Url.Action("PayableInvoiceMainEditor", "Payables", new { warehouseTransactionIds ="_transactionIds_",payeeId = "_payeeId_", payeeType="Vendor" })))';

on javascript file

var url = _addInvoiceUrl.replace('_transactionIds_', warehouseTransactionIds).replace('_payeeId_', payeeId);
        window.location.href = url;

in this way i can able to pass the parameter values on demand..

by using @Html.Raw, url will not get amp; for parameters

I used to add the Ruby Racer to the Gem file to fix it. But hey, Node.js works!

There are 4 versions of the CRT link libraries present in vc\lib:

• libcmt.lib: static CRT link library for a release build (/MT)
• libcmtd.lib: static CRT link library for a debug build (/MTd)
• msvcrt.lib: import library for the release DLL version of the CRT (/MD)
• msvcrtd.lib: import library for the debug DLL version of the CRT (/MDd)

Look at the linker options, Project + Properties, Linker, Command Line. Note how these libraries are not mentioned here. The linker automatically figures out what /M switch was used by the compiler and which .lib should be linked through a #pragma comment directive. Kinda important, you'd get horrible link errors and hard to diagnose runtime errors if there was a mismatch between the /M option and the .lib you link with.

You'll see the error message you quoted when the linker is told both to link to msvcrt.lib and libcmt.lib. Which will happen if you link code that was compiled with /MT with code that was linked with /MD. There can be only one version of the CRT.

/NODEFAULTLIB tells the linker to ignore the #pragma comment directive that was generated from the /MT compiled code. This might work, although a slew of other linker errors is not uncommon. Things like errno, which is a extern int in the static CRT version but macro-ed to a function in the DLL version. Many others like that.

Well, fix this problem the Right Way, find the .obj or .lib file that you are linking that was compiled with the wrong /M option. If you have no clue then you could find it by grepping the .obj/.lib files for "/MT"

Btw: the Windows executables (like version.dll) have their own CRT version to get their job done. It is located in c:\windows\system32, you cannot reliably use it for your own programs, its CRT headers are not available anywhere. The CRT DLL used by your program has a different name (like msvcrt90.dll).

Gradle Build Tools 2.2.0+ - The closest the NDK has ever come to being called 'magic'

In trying to avoid experimental and frankly fed up with the NDK and all its hackery I am happy that 2.2.x of the Gradle Build Tools came out and now it just works. The key is the externalNativeBuild and pointing ndkBuild path argument at an Android.mk or change ndkBuild to cmake and point the path argument at a CMakeLists.txt build script.

android {
    compileSdkVersion 19
    buildToolsVersion "25.0.2"

    defaultConfig {
        minSdkVersion 19
        targetSdkVersion 19

        ndk {
            abiFilters 'armeabi', 'armeabi-v7a', 'x86'
        }

        externalNativeBuild {
            cmake {
                cppFlags '-std=c++11'
                arguments '-DANDROID_TOOLCHAIN=clang',
                        '-DANDROID_PLATFORM=android-19',
                        '-DANDROID_STL=gnustl_static',
                        '-DANDROID_ARM_NEON=TRUE',
                        '-DANDROID_CPP_FEATURES=exceptions rtti'
            }
        }
    }

    externalNativeBuild {
        cmake {
             path 'src/main/jni/CMakeLists.txt'
        }
        //ndkBuild {
        //   path 'src/main/jni/Android.mk'
        //}
    }
}

For much more detail check Google's page on adding native code.

After this is setup correctly you can ./gradlew installDebug and off you go. You will also need to be aware that the NDK is moving to clang since gcc is now deprecated in the Android NDK.

Android Studio Clean and Build Integration - DEPRECATED

The other answers do point out the correct way to prevent the automatic creation of Android.mk files, but they fail to go the extra step of integrating better with Android Studio. I have added the ability to actually clean and build from source without needing to go to the command-line. Your local.properties file will need to have ndk.dir=/path/to/ndk

apply plugin: 'com.android.application'

android {
    compileSdkVersion 14
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "com.example.application"
        minSdkVersion 14
        targetSdkVersion 14

        ndk {
            moduleName "YourModuleName"
        }
    }

    sourceSets.main {
        jni.srcDirs = [] // This prevents the auto generation of Android.mk
        jniLibs.srcDir 'src/main/libs' // This is not necessary unless you have precompiled libraries in your project.
    }

    task buildNative(type: Exec, description: 'Compile JNI source via NDK') {
        def ndkDir = android.ndkDirectory
        commandLine "$ndkDir/ndk-build",
                '-C', file('src/main/jni').absolutePath, // Change src/main/jni the relative path to your jni source
                '-j', Runtime.runtime.availableProcessors(),
                'all',
                'NDK_DEBUG=1'
    }

    task cleanNative(type: Exec, description: 'Clean JNI object files') {
        def ndkDir = android.ndkDirectory
        commandLine "$ndkDir/ndk-build",
                '-C', file('src/main/jni').absolutePath, // Change src/main/jni the relative path to your jni source
                'clean'
    }

    clean.dependsOn 'cleanNative'

    tasks.withType(JavaCompile) {
        compileTask -> compileTask.dependsOn buildNative
    }
}

dependencies {
    compile 'com.android.support:support-v4:20.0.0'
}

The src/main/jni directory assumes a standard layout of the project. It should be the relative from this build.gradle file location to the jni directory.

Gradle - for those having issues

Also check this Stack Overflow answer.

It is really important that your gradle version and general setup are correct. If you have an older project I highly recommend creating a new one with the latest Android Studio and see what Google considers the standard project. Also, use gradlew. This protects the developer from a gradle version mismatch. Finally, the gradle plugin must be configured correctly.

And you ask what is the latest version of the gradle plugin? Check the tools page and edit the version accordingly.

Final product - /build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

// Running 'gradle wrapper' will generate gradlew - Getting gradle wrapper working and using it will save you a lot of pain.
task wrapper(type: Wrapper) {
    gradleVersion = '2.2'
}

// Look Google doesn't use Maven Central, they use jcenter now.
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.2.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

Make sure gradle wrapper generates the gradlew file and gradle/wrapper subdirectory. This is a big gotcha.

ndkDirectory

This has come up a number of times, but android.ndkDirectory is the correct way to get the folder after 1.1. Migrating Gradle Projects to version 1.0.0. If you're using an experimental or ancient version of the plugin your mileage may vary.

Update 2020...

Bootstrap 5 Beta

The Navbar is still flexbox based in Bootstrap 5 and centering content works the same as it did with Bootstrap 4. Examples

Bootstrap 4

Centering Navbar content is easier is Bootstrap 4, and you can see many centering scenarios explained here: https://stackoverflow.com/a/20362024/171456

Bootstrap 3

Another scenario that doesn't seem to have been answered yet is centering both the brand and navbar links. Here's a solution..

.navbar .navbar-header,
.navbar-collapse {
    float:none;
    display:inline-block;
    vertical-align: top;
}

@media (max-width: 768px) {
    .navbar-collapse  {
        display: block;
    }
}

If you're in an async function you can simply do it in one line:

console.log(1);
await new Promise(resolve => setTimeout(resolve, 3000)); // 3 sec
console.log(2);

FYI, if target is NodeJS you can use this if you want (it's a predefined promisified setTimeout function):

await setTimeout[Object.getOwnPropertySymbols(setTimeout)[0]](3000) // 3 sec

You can't make window.open modal and I strongly recommend you not to go that way. Instead you can use something like jQuery UI's dialog widget.

UPDATE:

You can use load() method:

$("#dialog").load("resource.php").dialog({options});

This way it would be faster but the markup will merge into your main document so any submit will be applied on the main window.

And you can use an IFRAME:

$("#dialog").append($("<iframe></iframe>").attr("src", "resource.php")).dialog({options});

This is slower, but will submit independently.

<?php
 $query = "select username from users";
 $res = mysqli_query($connection, $query);   
?>


<form>
  <select>
     <?php
       while ($row = $res->fetch_assoc()) 
       {
         echo '<option value=" '.$row['id'].' "> '.$row['name'].' </option>';
       }
    ?>
  </select>
</form>

Here's another variation of the solution that returns true if the string can be converted to a DateTime type, and false otherwise.

public static bool IsDateTime(string txtDate)
{
    DateTime tempDate;
    return DateTime.TryParse(txtDate, out tempDate);
}

This Quick Reference looks pretty good if you're looking for a language reference. It's especially geared towards the user interface portion of the API.

For the complete API, however, I always use the Javadoc. I reference it constantly.

Hitting ctrl + c once(wait for traceback), then hitting ctrl+c again did the trick for me :)

WinPython is an open-source distribution that has 64-bit NumPy and SciPy.

I have no idea why the other answers didn't work for me (error 500) but this works

@GetMapping("")
public String getAll() {
    List<Entity> entityList = entityManager.findAll();
    List<JSONObject> entities = new ArrayList<JSONObject>();
    for (Entity n : entityList) {
        JSONObject Entity = new JSONObject();
        entity.put("id", n.getId());
        entity.put("address", n.getAddress());
        entities.add(entity);
    }
    return entities.toString();
}

It's not really a bug, just a difference in implantation by the browser vendors.

As a rule avoid browser sniffing. There is a nifty jQuery fix which is hinted at in the answers.

This is what works for me: $('html:not(:animated),body:not(:animated)').scrollTop()

They both track your changes to the collection, just call the SaveChanges() method that should update the DB.

This will replace all the characters except alphanumeric

replaceAll("[^A-Za-z0-9]","");

Try something like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    Write-Host $_.Exception.ToString()
}

The exception is in the $_ variable. You might explore $_ like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    $_ | fl * -Force
}

I think it will give you all the info you need.

My rule: if there is some data that is not displayed, try to use -force.

Direct quote from MSDN: <xsd:import> Element, Remarks section

The difference between the include element and the import element is that import element allows references to schema components from schema documents with different target namespaces and the include element adds the schema components from other schema documents that have the same target namespace (or no specified target namespace) to the containing schema. In short, the import element allows you to use schema components from any schema; the include element allows you to add all the components of an included schema to the containing schema.

Typically, git commit brings up an interactive editor (on Linux, and possibly Cygwin, determined by the contents of your $EDITOR environment variable) for you to edit your commit message in. When you save and exit, the commit completes.

You should make sure that the changes you are trying to commit have been added to the Git index; this determines what is committed. See http://gitref.org/basic/ for details on this.

You can access it by the class' private attributes:

cls_name = self.__class__.__name__

EDIT:

As said by Ned Batcheler, this wouldn't work in the class body, but it would in a method.

You can also do (Get-Service -Name "what ever" - ComputerName RemoteHost).Status = "Stopped"

I recognize that the answer works and has been accepted but there is a much cleaner way to write that query. Tested on mysql and postgres.

We can do it by simple means:

In FirstActivity:

Intent intent = new Intent(FirstActivity.this, SecondActivity.class);
intent.putExtra("uid", uid.toString());
intent.putExtra("pwd", pwd.toString());
startActivity(intent);

In SecondActivity:

    try {
        Intent intent = getIntent();

        String uid = intent.getStringExtra("uid");
        String pwd = intent.getStringExtra("pwd");

    } catch (Exception e) {
        e.printStackTrace();
        Log.e("getStringExtra_EX", e + "");
    }

I think you want to set

Also there is a jQuery plugin that adds some methods on an array:

Implementing Prototype’s Array Methods in jQuery

This plugin implements Prototype's library array methods such as:

var arr = [1,2,3,4,5,6];
$.protify(arr, true);
arr.all();  // true

var arr = $.protify([1, 2, 3, 4, 5, 6]);
arr.any(); // true

And more.

It's impossible to instantiate an abstract class. What you really can do, has implement some common methods in an abstract class and let others unimplemented (declaring them abstract) and let the concrete descender implement them depending on their needs. Then you can make a factory, which returns an instance of this abstract class (actually his implementer). In the factory you then decide, which implementer to choose. This is known as a factory design pattern:

   public abstract class AbstractGridManager {
        private LifecicleAlgorithmIntrface lifecicleAlgorithm;
        // ... more private fields

        //Method implemented in concrete Manager implementors 
        abstract public Grid initGrid();

        //Methods common to all implementors
        public Grid calculateNextLifecicle(Grid grid){
            return this.getLifecicleAlgorithm().calculateNextLifecicle(grid);
        }

        public LifecicleAlgorithmIntrface getLifecicleAlgorithm() {
            return lifecicleAlgorithm;
        }
        public void setLifecicleAlgorithm(LifecicleAlgorithmIntrface lifecicleAlgorithm) {
            this.lifecicleAlgorithm = lifecicleAlgorithm;
        }
        // ... more common logic and getters-setters pairs
    }

The concrete implementer only needs to implement the methods declared as abstract, but will have access to the logic implemented in those classes in an abstract class, which are not declared abstract:

public class FileInputGridManager extends AbstractGridManager {

private String filePath;

//Method implemented in concrete Manager implementors 
abstract public Grid initGrid();

public class FileInputGridManager extends AbstractGridManager {

    private String filePath;

    //Method implemented in concrete Manager implementors 
    abstract public Grid initGrid();

    public Grid initGrid(String filePath) {
        List<Cell> cells = new ArrayList<>();
        char[] chars;
        File file = new File(filePath); // for example foo.txt
        // ... more logic
        return grid;
    }
}

Then finally the factory looks something like this:

public class GridManagerFactory {
    public static AbstractGridManager getGridManager(LifecicleAlgorithmIntrface lifecicleAlgorithm, String... args){
        AbstractGridManager manager = null;

        // input from the command line
        if(args.length == 2){
            CommandLineGridManager clManager = new CommandLineGridManager();
            clManager.setWidth(Integer.parseInt(args[0]));
            clManager.setHeight(Integer.parseInt(args[1]));
            // possibly more configuration logic
            ...
            manager = clManager;
        } 
        // input from the file
        else if(args.length == 1){
            FileInputGridManager fiManager = new FileInputGridManager();
            fiManager.setFilePath(args[0]);
            // possibly more method calls from abstract class
            ...
            manager = fiManager ;
        }
        //... more possible concrete implementors
        else{
            manager = new CommandLineGridManager();
        }
        manager.setLifecicleAlgorithm(lifecicleAlgorithm);
        return manager;
    }
}

The receiver of AbstractGridManager would call the methods on him and get the logic, implemented in the concrete descender (and partially in the abstract class methods) without knowing what is the concrete implementation he got. This is also known as inversion of control or dependency injection.

            Statement st = con.createStatement();

            ResultSet rs = st.executeQuery("select * from tablename ");
            ResultSetMetaData rsmd = rs.getMetaData();

            while (rs.next()) {

                result += rsmd.getColumnName(1) + ": " + rs.getString(1) + "\n";

            }
            tv.setText(result);
        } catch (Exception e) {
            e.printStackTrace();
            tv.setText(e.toString());
        }

    }

In Win10 it might be helpful to download VirtualBox latest version.

It was the only thing that solved it for me. Hope it will save someone some time and trouble.

Officially google provide an Android API for this.

The API is currently being tested with a handful of partners, and will become available to all developers soon.

Update API is available now - https://developer.android.com/guide/app-bundle/in-app-updates

What about something like this.

<div id="movie_item">
    <div class="movie_item_poster">
        <img src="..." style="max-width: 100%; max-height: 100%;">
    </div>

     <div id="movie_item_content">
        <div class="movie_item_content_year">year</div>
        <div class="movie_item_content_title">title</div>
        <div class="movie_item_content_plot">plot</div>
    </div>

    <div class="movie_item_toolbar">
        Lorem Ipsum...
    </div>
</div>

You don't have to float both movie_item_poster AND movie_item_content. Just float one of them...

#movie_item {
    position: relative;
    margin-top: 10px;
    height: 175px;
}

.movie_item_poster {
    float: left;
    height: 150px;
    width: 100px;
}

.movie_item_content {
    position: relative;
}

.movie_item_content_title {
}

.movie_item_content_year {
    float: right;
}

.movie_item_content_plot {
}

.movie_item_toolbar {
    clear: both;
    vertical-align: bottom;
    width: 100%;
    height: 25px;
}

Here it is as a JSFiddle.

https://stackoverflow.com/a/17637937/3174065 it is answered here though this method does use some JS. if used, be sure to put the js in the footer, the body has to be fully loaded for this to fire properly, when placed in the head it errors because it fires before the body is loaded.

it then adds a .safari class to the body, but only in safari, making targeting the css very easy.

Create Learning Table:

CREATE TABLE "public"."learning" (
    "api_id" int4 DEFAULT nextval('share_api_api_id_seq'::regclass) NOT NULL,
    "title" varchar(255) COLLATE "default"
);

Insert Data Learning Table:

INSERT INTO "public"."learning" VALUES ('1', 'Google AI-01');
INSERT INTO "public"."learning" VALUES ('2', 'Google AI-02');
INSERT INTO "public"."learning" VALUES ('3', 'Google AI-01');

Step: 01

CREATE OR REPLACE FUNCTION get_all (pattern VARCHAR) RETURNS TABLE (
        learn_id INT,
        learn_title VARCHAR
) AS $$
BEGIN
    RETURN QUERY SELECT
        api_id,
        title
    FROM
        learning
    WHERE
        title = pattern ;
END ; $$ LANGUAGE 'plpgsql';

Step: 02

SELECT * FROM get_all('Google AI-01');

Step: 03

DROP FUNCTION get_all();

Demo:

Make sure their GroupName properties are set to the same name:

<asp:RadioButton GroupName="MeasurementSystem" runat="server" Text="US" />
<asp:RadioButton GroupName="MeasurementSystem" runat="server" Text="Metric" />

You can use regular expressions like this:

SELECT * FROM pet WHERE name REGEXP 'Bob|Smith'; 

Very compact, kotlin version:

tvTitle.apply { 
    text = "foobar"
    paint?.isUnderlineText = true
}

Thank you @Razvan who pointed me in the right direction. I was able to get it in one line and I successfully hunted down the imports for Hamcrest 1.3.

the imports:

import static org.hamcrest.CoreMatchers.is;
import static org.hamcrest.Matchers.contains;
import static org.hamcrest.MatcherAssert.assertThat;
import static org.hamcrest.beans.HasPropertyWithValue.hasProperty;

the code:

assertThat( myClass.getMyItems(), contains(
    hasProperty("name", is("foo")), 
    hasProperty("name", is("bar"))
));

• <% %> : Executes the ruby code
• <%= %> : Prints into Erb file. Or browser
• <% -%> : Avoids line break after expression.

Since not all of my clients use authenticated SMTP accounts, I resorted to using the SMTP account only if app key values are supplied in web.config file.

Here is the VB code:

sSMTPUser = ConfigurationManager.AppSettings("SMTPUser")
sSMTPPassword = ConfigurationManager.AppSettings("SMTPPassword")

If sSMTPUser.Trim.Length > 0 AndAlso sSMTPPassword.Trim.Length > 0 Then
    NetClient.Credentials = New System.Net.NetworkCredential(sSMTPUser, sSMTPPassword)

    sUsingCredentialMesg = "(Using Authenticated Account) " 'used for logging purposes
End If

NetClient.Send(Message)

Let's assume you want to overwrite the same file:

import json

with open('data.json', 'r') as data_file:
    data = json.load(data_file)

for element in data:
    element.pop('hours', None)

with open('data.json', 'w') as data_file:
    data = json.dump(data, data_file)

dict.pop(<key>, not_found=None) is probably what you where looking for, if I understood your requirements. Because it will remove the hours key if present and will not fail if not present.

However I am not sure I understand why it makes a difference to you whether the hours key contains some days or not, because you just want to get rid of the whole key / value pair, right?

Now, if you really want to use del instead of pop, here is how you could make your code work:

import json

with open('data.json') as data_file:
    data = json.load(data_file)

for element in data:
    if 'hours' in element:
        del element['hours']

with open('data.json', 'w') as data_file:
    data = json.dump(data, data_file)

EDIT So, as you can see, I added the code to write the data back to the file. If you want to write it to another file, just change the filename in the second open statement.

I had to change the indentation, as you might have noticed, so that the file has been closed during the data cleanup phase and can be overwritten at the end.

with is what is called a context manager, whatever it provides (here the data_file file descriptor) is available ONLY within that context. It means that as soon as the indentation of the with block ends, the file gets closed and the context ends, along with the file descriptor which becomes invalid / obsolete.

Without doing this, you wouldn't be able to open the file in write mode and get a new file descriptor to write into.

I hope it's clear enough...

SECOND EDIT

This time, it seems clear that you need to do this:

with open('dest_file.json', 'w') as dest_file:
    with open('source_file.json', 'r') as source_file:
        for line in source_file:
            element = json.loads(line.strip())
            if 'hours' in element:
                del element['hours']
            dest_file.write(json.dumps(element))

The dat file has some lines of extra information before the actual data. Skip them with the skip argument:

read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
           header=TRUE, skip=3)

An easy way to check this if you are unfamiliar with the dataset is to first use readLines to check a few lines, as below:

readLines("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
          n=10)
# [1] "Ozone data from CZ03 2009"   "Local time: GMT + 0"        
# [3] ""                            "Date        Hour      Value"
# [5] "01.01.2009 00:00       34.3" "01.01.2009 01:00       31.9"
# [7] "01.01.2009 02:00       29.9" "01.01.2009 03:00       28.5"
# [9] "01.01.2009 04:00       32.9" "01.01.2009 05:00       20.5"

Here, we can see that the actual data starts at [4], so we know to skip the first three lines.

Update

If you really only wanted the Value column, you could do that by:

as.vector(
    read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
               header=TRUE, skip=3)$Value)

Again, readLines is useful for helping us figure out the actual name of the columns we will be importing.

But I don't see much advantage to doing that over reading the whole dataset in and extracting later.

Custom domain SSL certs were just added today for $600/cert/month. Sign up for your invite below: http://aws.amazon.com/cloudfront/custom-ssl-domains/

Update: SNI customer provided certs are now available for no additional charge. Much cheaper than $600/mo, and with XP nearly killed off, it should work well for most use cases.

@skalee AWS has a mechanism for achieving what the poster asks for, "implement SSL for an Amazon s3 bucket", it's called CloudFront. I'm reading "implement" as "use my SSL certs," not "just put an S on the HTTP URL which I'm sure the OP could have surmised.

Since CloudFront costs exactly the same as S3 ($0.12/GB), but has a ton of additional features around SSL AND allows you to add your own SNI cert at no additional cost, it's the obvious fix for "implementing SSL" on your domain.

it is simple just use .qsize() example:

a=Queue()
a.put("abcdef")
print a.qsize() #prints 1 which is the size of queue

The above snippet applies for Queue() class of python. Thanks @rayryeng for the update.

for deque from collections we can use len() as stated here by K Z.

Ok, I had the same problem.I came up with this solution.It worked for me the best.I did try atoi() but didn't work well for me.So here is my solution:

void splitInput(int arr[], int sizeArr, char num[])
{
    for(int i = 0; i < sizeArr; i++)
        // We are subtracting 48 because the numbers in ASCII starts at 48.
        arr[i] = (int)num[i] - 48;
}

curr = head;
prev = NULL;

while (curr != NULL) {
    next = curr->next; // store current's next, since it will be overwritten
    curr->next = prev;
    prev = curr;
    curr = next;
}

head = prev; // update head

Quotes!

if [ "$1" != -v ]; then

Otherwise, when $1 is completely empty, your test becomes:

[ != -v ]

instead of

[ "" != -v ]

...and != is not a unary operator (that is, one capable of taking only a single argument).

You derive B from A<B>, so the first thing the compiler does, once it sees the definition of class B is to try to instantiate A<B>. To do this it needs to known B::mytype for the parameter of action. But since the compiler is just in the process of figuring out the actual definition of B, it doesn't know this type yet and you get an error.

One way around this is would be to declare the parameter type as another template parameter, instead of inside the derived class:

template<typename Subclass, typename Param>
class A {
    public:
        void action(Param var) {
                (static_cast<Subclass*>(this))->do_action(var);
        }
};

class B : public A<B, int> { ... };

For a single keyword on VARCHAR fields you can use LIKE:

SELECT id, category, location
FROM table
WHERE
(
    category LIKE '%keyword%'
    OR location LIKE '%keyword%'
)

For a description you're usually better adding a full text index and doing a Full-Text Search (MyISAM only):

SELECT id, description
FROM table
WHERE MATCH (description) AGAINST('keyword1 keyword2')

https://www.postgresql.org/docs/8.4/functions-formatting.html

SELECT to_char(date_field, 'DD/MM/YYYY')
FROM table

One example is when you write a parser function and pass it a source pointer to read from, if the function is supposed to push that pointer forward behind the last character which has been correctly recognized by the parser. Using a reference to a pointer makes it clear then that the function will move the original pointer to update its position.

In general, you use references to pointers if you want to pass a pointer to a function and let it move that original pointer to some other position instead of just moving a copy of it without affecting the original.

If you don't have the .PBO file:

C#

public int GetLineNumber(Exception ex)
{
    var lineNumber = 0;
    const string lineSearch = ":line ";
    var index = ex.StackTrace.LastIndexOf(lineSearch);
    if (index != -1)
    {
        var lineNumberText = ex.StackTrace.Substring(index + lineSearch.Length);
        if (int.TryParse(lineNumberText, out lineNumber))
        {
        }
    }
    return lineNumber;
}

Vb.net

Public Function GetLineNumber(ByVal ex As Exception)
    Dim lineNumber As Int32 = 0
    Const lineSearch As String = ":line "
    Dim index = ex.StackTrace.LastIndexOf(lineSearch)
    If index <> -1 Then
        Dim lineNumberText = ex.StackTrace.Substring(index + lineSearch.Length)
        If Int32.TryParse(lineNumberText, lineNumber) Then
        End If
    End If
    Return lineNumber
End Function

Or as an extentions on the Exception class

public static class MyExtensions
{
    public static int LineNumber(this Exception ex)
    {
        var lineNumber = 0;
        const string lineSearch = ":line ";
        var index = ex.StackTrace.LastIndexOf(lineSearch);
        if (index != -1)
        {
            var lineNumberText = ex.StackTrace.Substring(index + lineSearch.Length);
            if (int.TryParse(lineNumberText, out lineNumber))
            {
            }
        }
        return lineNumber;
    }
}   

Even if you don't control the server, you can still see the error messages by adding the following line to the Web.config file in your project (bewlow <system.web>):

<customErrors mode="off" />

Another approach is to wrap your table in a scrollable element and set the header cells to stick to the top.

The advantage of this approach is that you don't have to change the display on tbody and you can leave it to the browser to calculate column width while keeping the header cell widths in line with the data cell column widths.

This one worked for me

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_NOTHING);

Avoid loops. What you want to do is:

import numpy as np
data=np.loadtxt(fname="data.txt")## to load the above two column
print data
print data.sum(axis=1)

I am using OSX -v 10.10.4. The solution above is a quick & easy.

Happening OSX does not have the connection library by default.

First you should install the connector:

brew install mysql-connector-c

Then install with pip mysql

pip install mysql-python

You could use shallow clones (git > 1.9):

git clone --depth depth remote-url

This annotation is commonly used to eliminate NullPointerExceptions. @Nullable says that this parameter might be null. A good example of such behaviour can be found in Google Guice. In this lightweight dependency injection framework you can tell that this dependency might be null. If you would try to pass null without an annotation the framework would refuse to do it's job.

What is more @Nullable might be used with @NotNull annotation. Here you can find some tips on how to use them properly. Code inspection in IntelliJ checks the annotations and helps to debug the code.

New introduction 2

In the previous version of macro "SaveEmailDetails" I used this statement to find Inbox:

Set FolderTgt = CreateObject("Outlook.Application"). _
              GetNamespace("MAPI").GetDefaultFolder(olFolderInbox)

I have since installed a newer version of Outlook and I have discovered that it does not use the default Inbox. For each of my email accounts, it created a separate store (named for the email address) each with its own Inbox. None of those Inboxes is the default.

This macro, outputs the name of the store holding the default Inbox to the Immediate Window:

Sub DsplUsernameOfDefaultStore()

  Dim NS As Outlook.NameSpace
  Dim DefaultInboxFldr As MAPIFolder

  Set NS = CreateObject("Outlook.Application").GetNamespace("MAPI")
  Set DefaultInboxFldr = NS.GetDefaultFolder(olFolderInbox)

  Debug.Print DefaultInboxFldr.Parent.Name

End Sub

On my installation, this outputs: "Outlook Data File".

I have added an extra statement to macro "SaveEmailDetails" that shows how to access the Inbox of any store.

New introduction 1

A number of people have picked up the macro below, found it useful and have contacted me directly for further advice. Following these contacts I have made a few improvements to the macro so I have posted the revised version below. I have also added a pair of macros which together will return the MAPIFolder object for any folder with the Outlook hierarchy. These are useful if you wish to access other than a default folder.

The original text referenced one question by date which linked to an earlier question. The first question has been deleted so the link has been lost. That link was to Update excel sheet based on outlook mail (closed)

Original text

There are a surprising number of variations of the question: "How do I extract data from Outlook emails to Excel workbooks?" For example, two questions up on [outlook-vba] the same question was asked on 13 August. That question references a variation from December that I attempted to answer.

For the December question, I went overboard with a two part answer. The first part was a series of teaching macros that explored the Outlook folder structure and wrote data to text files or Excel workbooks. The second part discussed how to design the extraction process. For this question Siddarth has provided an excellent, succinct answer and then a follow-up to help with the next stage.

What the questioner of every variation appears unable to understand is that showing us what the data looks like on the screen does not tell us what the text or html body looks like. This answer is an attempt to get past that problem.

The macro below is more complicated than Siddarth’s but a lot simpler that those I included in my December answer. There is more that could be added but I think this is enough to start with.

The macro creates a new Excel workbook and outputs selected properties of every email in Inbox to create this worksheet:

Near the top of the macro there is a comment containing eight hashes (#). The statement below that comment must be changed because it identifies the folder in which the Excel workbook will be created.

All other comments containing hashes suggest amendments to adapt the macro to your requirements.

How are the emails from which data is to be extracted identified? Is it the sender, the subject, a string within the body or all of these? The comments provide some help in eliminating uninteresting emails. If I understand the question correctly, an interesting email will have Subject = "Task Completed".

The comments provide no help in extracting data from interesting emails but the worksheet shows both the text and html versions of the email body if they are present. My idea is that you can see what the macro will see and start designing the extraction process.

This is not shown in the screen image above but the macro outputs two versions on the text body. The first version is unchanged which means tab, carriage return, line feed are obeyed and any non-break spaces look like spaces. In the second version, I have replaced these codes with the strings [TB], [CR], [LF] and [NBSP] so they are visible. If my understanding is correct, I would expect to see the following within the second text body:

Activity[TAB]Count[CR][LF]Open[TAB]35[CR][LF]HCQA[TAB]42[CR][LF]HCQC[TAB]60[CR][LF]HAbst[TAB]50 45 5 2 2 1[CR][LF] and so on

Extracting the values from the original of this string should not be difficult.

I would try amending my macro to output the extracted values in addition to the email’s properties. Only when I have successfully achieved this change would I attempt to write the extracted data to an existing workbook. I would also move processed emails to a different folder. I have shown where these changes must be made but give no further help. I will respond to a supplementary question if you get to the point where you need this information.

Good luck.

JUnit 5 (Jupiter) provides three functions to check exception absence/presence:

? assertAll?()

  Asserts that all supplied executables
  do not throw exceptions.

? assertDoesNotThrow?()

  Asserts that execution of the
  supplied executable/supplier
  does not throw any kind of exception.

  This function is available
  since JUnit 5.2.0 (29 April 2018).

? assertThrows?()

  Asserts that execution of the supplied executable
  throws an exception of the expectedType
  and returns the exception.

export PATH=/usr/pgsql-9.2/bin:$PATH

The program executable psql is in the directory /usr/pgsql-9.2/bin, and that directory is not included in the path by default, so we have to tell our shell (terminal) program where to find psql. When most packages are installed, they are added to an existing path, such as /usr/local/bin, but not this program.

So we have to add the program's path to the shell PATH variable if we do not want to have to type the complete path to the program every time we execute it.

This line should typically be added to theshell startup script, which for the bash shell will be in the file ~/.bashrc.

In my case i am setting security mode to "TransportCredentialOnly" instead of "Transport" in binding. Changing it resolved the issue

<bindings>
  <webHttpBinding>
    <binding name="webHttpSecure">
      <security mode="Transport">
        <transport clientCredentialType="Windows" ></transport>
      </security>
      </binding>
  </webHttpBinding>
</bindings>

You may go with Plotly library. It can render interactive 3D plots directly in Jupyter Notebooks.

To do so you first need to install Plotly by running:

pip install plotly

You might also want to upgrade the library by running:

pip install plotly --upgrade

After that in you Jupyter Notebook you may write something like:

# Import dependencies
import plotly
import plotly.graph_objs as go

# Configure Plotly to be rendered inline in the notebook.
plotly.offline.init_notebook_mode()

# Configure the trace.
trace = go.Scatter3d(
    x=[1, 2, 3],  # <-- Put your data instead
    y=[4, 5, 6],  # <-- Put your data instead
    z=[7, 8, 9],  # <-- Put your data instead
    mode='markers',
    marker={
        'size': 10,
        'opacity': 0.8,
    }
)

# Configure the layout.
layout = go.Layout(
    margin={'l': 0, 'r': 0, 'b': 0, 't': 0}
)

data = [trace]

plot_figure = go.Figure(data=data, layout=layout)

# Render the plot.
plotly.offline.iplot(plot_figure)

As a result the following chart will be plotted for you in Jupyter Notebook and you'll be able to interact with it. Of course you will need to provide your specific data instead of suggeseted one.

It just so happens that I wrote a BigFraction class not too long ago, for Project Euler problems. It keeps a BigInteger numerator and denominator, so it'll never overflow. But it'll be a tad slow for a lot of operations that you know will never overflow.. anyway, use it if you want it. I've been dying to show this off somehow. :)

Edit: Latest and greatest version of this code, including unit tests is now hosted on GitHub and also available via Maven Central. I'm leaving my original code here so that this answer isn't just a link...

I've used Anna-Karenina's answer, and it works almost great with a very serious bug.

If you're using sections, long-pressing the section title will give you a wrong result of pressing the first row on that section, I've added a fixed version below (including the filtering of dummy calls based on the gesture state, per Anna-Karenina suggestion).

Guava has a "toString" method for reading a file into a String:

import com.google.common.base.Charsets;
import com.google.common.io.Files;

String content = Files.toString(new File("/home/x1/text.log"), Charsets.UTF_8);

This method does not require the file to be in the classpath (as in Jon Skeet previous answer).

It's almost always advisable to not use scriptlets in your JSP. They're considered bad form. Instead, try using JSTL (JSP Standard Tag Library) combined with EL (Expression Language) to run the conditional logic you're trying to do. As an added benefit, JSTL also includes other important features like looping.

Instead of:

<%String user=request.getParameter("user"); %>
<%if(user == null || user.length() == 0){
    out.print("I see! You don't have a name.. well.. Hello no name");   
}
else {%>
    <%@ include file="response.jsp" %>
<% } %>

Use:

<c:choose>
    <c:when test="${empty user}">
        I see!  You don't have a name.. well.. Hello no name
    </c:when>
    <c:otherwise>
        <%@ include file="response.jsp" %>
    </c:otherwise>
</c:choose>

Also, unless you plan on using response.jsp somewhere else in your code, it might be easier to just include the html in your otherwise statement:

<c:otherwise>
    <h1>Hello</h1>
    ${user}
</c:otherwise>

Also of note. To use the core tag, you must import it as follows:

 <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

You want to make it so the user will receive a message when the user submits a username. The easiest way to do this is to not print a message at all when the "user" param is null. You can do some validation to give an error message when the user submits null. This is a more standard approach to your problem. To accomplish this:

In scriptlet:

<% String user = request.getParameter("user");
   if( user != null && user.length() > 0 ) {
       <%@ include file="response.jsp" %>
   }
%>

In jstl:

<c:if test="${not empty user}">
    <%@ include file="response.jsp" %>
</c:if>

This is what I ended up using to take the value from an input, expanding numbers less than 17digits and converting Exponential numbers to x10^y

// e.g.
//  niceNumber("1.24e+4")   becomes 
// 1.24x10 to the power of 4 [displayed in Superscript]

function niceNumber(num) {
  try{
        var sOut = num.toString();
      if ( sOut.length >=17 || sOut.indexOf("e") > 0){
      sOut=parseFloat(num).toPrecision(5)+"";
      sOut = sOut.replace("e","x10<sup>")+"</sup>";
      }
      return sOut;

  }
  catch ( e) {
      return num;
  }
}

If you just want to compare only one row with $lactureName then use following

function checkLectureStatus($lectureName)
{
 $con = connectvar();
 mysql_select_db("mydatabase", $con);
 $result = mysql_query("SELECT * FROM preditors_assigned WHERE lecture_name='$lectureName'");
  if(mysql_num_rows($result) > 0)
  {
         mysql_close($con);
         return "Assigned";
  }
  else
  {
        mysql_close($con);
        return "Available";
  }
}

Why does everyone like to list out source files? A simple find command can take care of that easily.

Here's an example of a dirt simple C++ Makefile. Just drop it in a directory containing .C files and then type make...

appname := myapp

CXX := clang++
CXXFLAGS := -std=c++11

srcfiles := $(shell find . -name "*.C")
objects  := $(patsubst %.C, %.o, $(srcfiles))

all: $(appname)

$(appname): $(objects)
    $(CXX) $(CXXFLAGS) $(LDFLAGS) -o $(appname) $(objects) $(LDLIBS)

depend: .depend

.depend: $(srcfiles)
    rm -f ./.depend
    $(CXX) $(CXXFLAGS) -MM $^>>./.depend;

clean:
    rm -f $(objects)

dist-clean: clean
    rm -f *~ .depend

include .depend

If some item(s) exist in both lists you may use

var all = list1.Concat(list2).Concat(list3) ... Concat(listN).Distinct().ToList();

This is from the Docker documentation itself, might be of help, simple and plain:

"The host directory is, by its nature, host-dependent. For this reason, you can’t mount a host directory from Dockerfile, the VOLUME instruction does not support passing a host-dir, because built images should be portable. A host directory wouldn’t be available on all potential hosts.".

Lazy notes in comments.

#include <stdio.h>

#include <stdlib.h>

// you need the prototype
char *substring(int i,int j,char *ch);


int main(void /* std compliance */)
{
  int i=0,j=2;
  char s[]="String";
  char *test;
  // s points to the first char, S
  // *s "is" the first char, S
  test=substring(i,j,s); // so s only is ok
  // if test == NULL, failed, give up
  printf("%s",test);
  free(test); // you should free it
  return 0;
}


char *substring(int i,int j,char *ch)
{
  int k=0;
  // avoid calc same things several time
  int n = j-i+1; 
  char *ch1;
  // you can omit casting - and sizeof(char) := 1
  ch1=malloc(n*sizeof(char));
  // if (!ch1) error...; return NULL;

  // any kind of check missing:
  // are i, j ok? 
  // is n > 0... ch[i] is "inside" the string?...
  while(k<n)
    {   
      ch1[k]=ch[i];
      i++;k++;
    }   

  return ch1;
}

I think the problem is given in the error message, although it is not very easy to spot:

IndexError: too many indices for array
xs  = data[:, col["l1"     ]]

'Too many indices' means you've given too many index values. You've given 2 values as you're expecting data to be a 2D array. Numpy is complaining because data is not 2D (it's either 1D or None).

This is a bit of a guess - I wonder if one of the filenames you pass to loadfile() points to an empty file, or a badly formatted one? If so, you might get an array returned that is either 1D, or even empty (np.array(None) does not throw an Error, so you would never know...). If you want to guard against this failure, you can insert some error checking into your loadfile function.

I highly recommend in your for loop inserting:

print(data)

This will work in Python 2.x or 3.x and might reveal the source of the issue. You might well find it is only one value of your outputs_l1 list (i.e. one file) that is giving the issue.

For texts in angular template (userType is property of $scope, like $scope.userType):

<span>
  {{userType=='admin' ? 'Edit' : 'Show'}}
</span>

On Vue 2.3 and above you can do this:

<div v-on:click="firstFunction(); secondFunction();"></div>
// or
<div @click="firstFunction(); secondFunction();"></div>

If you are using React, make sure autoplay is set to,

autoPlay

React wants it to be camelcase!

To filter a list of dicts you can use the selectattr filter together with the equalto test:

network.addresses.private_man | selectattr("type", "equalto", "fixed")

The above requires Jinja2 v2.8 or later (regardless of Ansible version).

Ansible also has the tests match and search, which take regular expressions:

match will require a complete match in the string, while search will require a match inside of the string.

network.addresses.private_man | selectattr("type", "match", "^fixed$")

To reduce the list of dicts to a list of strings, so you only get a list of the addr fields, you can use the map filter:

... | map(attribute='addr') | list

Or if you want a comma separated string:

... | map(attribute='addr') | join(',')

Combined, it would look like this.

- debug: msg={{ network.addresses.private_man | selectattr("type", "equalto", "fixed") | map(attribute='addr') | join(',') }}

If you're trying to open a scala/sbt project, the sbt version set in /project/build.properties must match the sbt version installed on your system or intellij won't detect your project's modules properly.

Once that's done, you can just delete the idea folder and restart as the other answers suggest.

function Update(key, value)
{    
    for (var i = 0; i < array.length; i++) {
        if (array[i].Key == key) {
            array[i].Value = value; 
            break;
        }
    }
}

That's a difficult problem to solve since visually similar PDFs may have a wildly differing structure depending on how they were produced. In the worst case the library would need to basically act like an OCR. On the other hand, the PDF may contain sufficient structure and metadata for easy removal of tables and figures, which the library can be tailored to take advantage of.

I'm pretty sure there are no open source tools which solve your problem for a wide variety of PDFs, but I remember having heard of commercial software claiming to do exactly what you ask for. I'm sure you'll run into them while googling.

Most likely the TinyMce editor is adding its own formatting to the post. You'll need to see how you can escape TinyMce's editing abilities. The code works fine for me. Is it a wordpress blog?

If using a StackTraceElement, use:

String fullClassName = stackTraceElement.getClassName();
String simpleClassName = fullClassName.substring(fullClassName.lastIndexOf('.') + 1);

System.out.println(simpleClassName);

You should use npm run-script build or npm build <project_folder>. More info here: https://docs.npmjs.com/cli/build.

You need to use the DataGridViewColumn.AutoSizeMode property.

You can use one of these values for column 0 and 1:

AllCells: The column width adjusts to fit the contents of all cells in the column, including the header cell.
AllCellsExceptHeader: The column width adjusts to fit the contents of all cells in the column, excluding the header cell.
DisplayedCells: The column width adjusts to fit the contents of all cells in the column that are in rows currently displayed onscreen, including the header cell.
DisplayedCellsExceptHeader: The column width adjusts to fit the contents of all cells in the column that are in rows currently displayed onscreen, excluding the header cell.

Then you use the Fill value for column 2

The column width adjusts so that the widths of all columns exactly fills the display area of the control...

this.DataGridView1.Columns[0].AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells;
this.DataGridView1.Columns[1].AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells;
this.DataGridView1.Columns[2].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;

As pointed out by other users, the default value can be set at datagridview level with DataGridView.AutoSizeColumnsMode property.

this.DataGridView1.Columns[0].AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells;
this.DataGridView1.Columns[1].AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells;

could be:

this.DataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.DisplayedCells;

Important note:

If your grid is bound to a datasource and columns are auto-generated (AutoGenerateColumns property set to True), you need to use the DataBindingComplete event to apply style AFTER columns have been created.

In some scenarios (change cells value by code for example), I had to call DataGridView1.AutoResizeColumns(); to refresh the grid.
