Have you added this gem to your gemfile?

# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'

move that gem out of assets group and then run bundle again, I hope that would help!

Can you invert your regex so split by the non operation characters?

String ops[] = string.split("[a-z]")
// ops == [+, -, *, /, <, >, >=, <=, == ]   

This obviously doesn't return the variables in the array. Maybe you can interleave two splits (one by the operators, one by the variables)

As has been suggested, using the string.format method is nice and simple and very readable.

In vb.net the " + " is used for addition and the " & " is used for string concatenation.

In your example:

MsgBox("Variable = " + variable)

becomes:

MsgBox("Variable = " & variable)

I may have been a bit quick answering this as it appears these operators can both be used for concatenation, but recommended use is the "&", source http://msdn.microsoft.com/en-us/library/te2585xw(v=VS.100).aspx

maybe call

variable.ToString()

update:

Use string interpolation (vs2015 onwards I believe):

MsgBox($"Variable = {variable}")

for finding out that user is new or old , Get user IP .

create a table for IPs and their visits timestamp .

check IF IP does not exists OR time()-saved_timestamp > 60*60*24 (for 1 day) ,edit the IP's timestamp to time() (means now) and increase your view one .

else , do nothing .

FYI : user IP is stored in $_SERVER['REMOTE_ADDR'] variable

what are Access Specifiers?

There are 3 access specifiers for a class/struct/Union in C++. These access specifiers define how the members of the class can be accessed. Of course, any member of a class is accessible within that class(Inside any member function of that same class). Moving ahead to type of access specifiers, they are:

Public - The members declared as Public are accessible from outside the Class through an object of the class.

Protected - The members declared as Protected are accessible from outside the class BUT only in a class derived from it.

Private - These members are only accessible from within the class. No outside Access is allowed.

An Source Code Example:

class MyClass
{
    public:
        int a;
    protected:
        int b;
    private:
        int c;
};

int main()
{
    MyClass obj;
    obj.a = 10;     //Allowed
    obj.b = 20;     //Not Allowed, gives compiler error
    obj.c = 30;     //Not Allowed, gives compiler error
}

Inheritance and Access Specifiers

Inheritance in C++ can be one of the following types:

• Private Inheritance
• Public Inheritance
• Protected inheritance

Here are the member access rules with respect to each of these:

First and most important rule Private members of a class are never accessible from anywhere except the members of the same class.

Public Inheritance:

All Public members of the Base Class become Public Members of the derived class &
All Protected members of the Base Class become Protected Members of the Derived Class.

i.e. No change in the Access of the members. The access rules we discussed before are further then applied to these members.

Code Example:

Class Base
{
    public:
        int a;
    protected:
        int b;
    private:
        int c;
};

class Derived:public Base
{
    void doSomething()
    {
        a = 10;  //Allowed 
        b = 20;  //Allowed
        c = 30;  //Not Allowed, Compiler Error
    }
};

int main()
{
    Derived obj;
    obj.a = 10;  //Allowed
    obj.b = 20;  //Not Allowed, Compiler Error
    obj.c = 30;  //Not Allowed, Compiler Error

}

Private Inheritance:

All Public members of the Base Class become Private Members of the Derived class &
All Protected members of the Base Class become Private Members of the Derived Class.

An code Example:

Class Base
{
    public:
      int a;
    protected:
      int b;
    private:
      int c;
};

class Derived:private Base   //Not mentioning private is OK because for classes it  defaults to private 
{
    void doSomething()
    {
        a = 10;  //Allowed 
        b = 20;  //Allowed
        c = 30;  //Not Allowed, Compiler Error
    }
};

class Derived2:public Derived
{
    void doSomethingMore()
    {
        a = 10;  //Not Allowed, Compiler Error, a is private member of Derived now
        b = 20;  //Not Allowed, Compiler Error, b is private member of Derived now
        c = 30;  //Not Allowed, Compiler Error
    }
};

int main()
{
    Derived obj;
    obj.a = 10;  //Not Allowed, Compiler Error
    obj.b = 20;  //Not Allowed, Compiler Error
    obj.c = 30;  //Not Allowed, Compiler Error

}

Protected Inheritance:

All Public members of the Base Class become Protected Members of the derived class &
All Protected members of the Base Class become Protected Members of the Derived Class.

A Code Example:

Class Base
{
    public:
        int a;
    protected:
        int b;
    private:
        int c;
};

class Derived:protected Base  
{
    void doSomething()
    {
        a = 10;  //Allowed 
        b = 20;  //Allowed
        c = 30;  //Not Allowed, Compiler Error
    }
};

class Derived2:public Derived
{
    void doSomethingMore()
    {
        a = 10;  //Allowed, a is protected member inside Derived & Derived2 is public derivation from Derived, a is now protected member of Derived2
        b = 20;  //Allowed, b is protected member inside Derived & Derived2 is public derivation from Derived, b is now protected member of Derived2
        c = 30;  //Not Allowed, Compiler Error
    }
};

int main()
{
    Derived obj;
    obj.a = 10;  //Not Allowed, Compiler Error
    obj.b = 20;  //Not Allowed, Compiler Error
    obj.c = 30;  //Not Allowed, Compiler Error
}

Remember the same access rules apply to the classes and members down the inheritance hierarchy.

Important points to note:

- Access Specification is per-Class not per-Object

Note that the access specification C++ work on per-Class basis and not per-object basis.
A good example of this is that in a copy constructor or Copy Assignment operator function, all the members of the object being passed can be accessed.

- A Derived class can only access members of its own Base class

Consider the following code example:

class Myclass
{ 
    protected: 
       int x; 
}; 

class derived : public Myclass
{
    public: 
        void f( Myclass& obj ) 
        { 
            obj.x = 5; 
        } 
};

int main()
{
    return 0;
}

It gives an compilation error:

prog.cpp:4: error: ‘int Myclass::x’ is protected

Because the derived class can only access members of its own Base Class. Note that the object obj being passed here is no way related to the derived class function in which it is being accessed, it is an altogether different object and hence derived member function cannot access its members.

What is a friend? How does friend affect access specification rules?

You can declare a function or class as friend of another class. When you do so the access specification rules do not apply to the friended class/function. The class or function can access all the members of that particular class.

So do friends break Encapsulation?

No they don't, On the contrary they enhance Encapsulation!

friendship is used to indicate a intentional strong coupling between two entities.
If there exists a special relationship between two entities such that one needs access to others private or protected members but You do not want everyone to have access by using the public access specifier then you should use friendship.

just a note: CPLUS_INCLUDE_PATH and C_INCLUDE_PATH are not the equivalent of LD_LIBRARY_PATH. LD_LIBRARY_PATH serves the ld (the dynamic linker at runtime) whereas the equivalent of the former two that serves your C/C++ compiler with the location of libraries is LIBRARY_PATH.

If ad hoc updates to system catalog is "not supported", or if you get a "Msg 5808" then you will need to configure with override like this:

EXEC sp_configure 'show advanced options', 1
RECONFIGURE with override
GO
EXEC sp_configure 'ad hoc distributed queries', 1
RECONFIGURE with override
GO

Scala:

Leaddetails.join(
    Utm_Master, 
    Leaddetails("LeadSource") <=> Utm_Master("LeadSource")
        && Leaddetails("Utm_Source") <=> Utm_Master("Utm_Source")
        && Leaddetails("Utm_Medium") <=> Utm_Master("Utm_Medium")
        && Leaddetails("Utm_Campaign") <=> Utm_Master("Utm_Campaign"),
    "left"
)

To make it case insensitive,

import org.apache.spark.sql.functions.{lower, upper}

then just use lower(value) in the condition of the join method.

Eg: dataFrame.filter(lower(dataFrame.col("vendor")).equalTo("fortinet"))

I had to get rid of the NULL values before using the command recommended by Andy above. An example:

df = pd.DataFrame(index = [0, 1, 2], columns=['first', 'second', 'third'])
df.ix[:, 'first'] = 'myword'
df.ix[0, 'second'] = 'myword'
df.ix[2, 'second'] = 'myword'
df.ix[1, 'third'] = 'myword'
df

    first   second  third
0   myword  myword   NaN
1   myword  NaN      myword 
2   myword  myword   NaN

Now running the command:

~df["second"].str.contains(word)

I get the following error:

TypeError: bad operand type for unary ~: 'float'

I got rid of the NULL values using dropna() or fillna() first and retried the command with no problem.

Use "javascript.validate.enable": false in your VS Code settings, It doesn't disable ESLINT. I use both ESLINT & Flow. Simply follow the instructions Flow For Vs Code Setup

Adding this line in settings.json. Helps "javascript.validate.enable": false

Another (!) issue to worry about is the possible change of implementation between early/late versions of Java. I don't believe the implementation details are set in stone, and so potentially an upgrade to a future Java version could cause problems.

Bottom line is, I wouldn't rely on the implementation of hashCode().

Perhaps you can highlight what problem you're actually trying to solve by using this mechanism, and that will highlight a more suitable approach.

The variable arguments must be the last of the parameters specified in your function declaration. If you try to specify another parameter after the variable arguments, the compiler will complain since there is no way to determine how many of the parameters actually belong to the variable argument.

void print(final String format, final String... arguments) {
    System.out.format( format, arguments );
}

I think, you are missing the @Bean annotation in your RequestController

Add the Bean in your file, this solved my issue
I got this solution while I was learning Spring Boot from tutorialspoint

private Applicant applicant;

@Bean 
public Applicant applicant() { 
    return new Applicant(); 
}

new calls the ctor of the object, delete call the dtor.

malloc & free just allocate and release raw memory.

Here is an easy way to fetch data from a MySQL database using PDO.

define("DB_HOST", "localhost");    // Using Constants
define("DB_USER", "YourUsername");
define("DB_PASS", "YourPassword");
define("DB_NAME", "Yourdbname");

$dbc = new PDO("mysql:host=".DB_HOST.";dbname=".DB_NAME.";charset-utf8mb4", DB_USER, DB_PASS);

$print = ""; // assign an empty string

$stmt = $dbc->query("SELECT * FROM tableName"); // fetch data
$stmt->setFetchMode(PDO::FETCH_OBJ);

$print .= '<table border="1px">';
$print .= '<tr><th>First name</th>';
$print .= '<th>Last name</th></tr>';

while ($names = $stmt->fetch()) { // loop and display data
    $print .= '<tr>';
    $print .= "<td>{$names->firstname}</td>";
    $print .= "<td>{$names->lastname}</td>";
    $print .= '</tr>';
}

$print .= "</table>";
echo $print;

I'll post my memo here, because I have to come back here again and again.

SCENARIO 1. Normal developer: You are developer who can't merge to master and have to play with feature branches only.

Case 1: master is a king. You want to refresh your feature branch (= rebase to master), because master contains new updates of dependencies and you want to overwrite your modest changes.

git checkout master
git pull

git checkout feature
git rebase -X ours master

Case 2: you are a king. You want to rebase your feature branch to master changes. But you did more than your colleagues had and want to use your own changes in a priority.

git checkout master
git pull

git checkout feature
git rebase -X theirs master

IMPORTANT: As you can see normal developers should prefer rebase and repeat it every morning like exercises/coffee.

SCENARIO 2. Merging-sensei: You are a team-lead and want to merge other branches and push a merged result directly to a master. master is a branch you will change.

Case 1: master is a king You want to merge third-party branch, but master is a priority. feature is a branch that your senior did.

git checkout feature
git pull

git checkout master
git merge -X ours feature

Case 2: new changes is a king When your senior developer released a cool feature and you want to overwrite the old s**t in the master branch.

git checkout feature
git pull

git checkout master
git merge -X theirs feature

REMEMBER: To remember in a midnight which one to choose: master is ours ALWAYS. And theirs is a feature that theirs have done.

In case you have ufw enabled, remember add ftp:

> sudo ufw allow ftp

It took me 2 days to realise that I enabled ufw.

You need to call p.Start() to actually run the process after you set the StartInfo. As it is, your function is probably hanging on the WaitForExit() call because the process was never actually started.

I tested below code with SQL Server 2008 R2 Express and I believe we should have solution for all 6 steps you outlined. Let's take on them one-by-one:

1 - Enable TCP/IP

We can enable TCP/IP protocol with WMI:

set wmiComputer = GetObject( _
    "winmgmts:" _
    & "\\.\root\Microsoft\SqlServer\ComputerManagement10")
set tcpProtocols = wmiComputer.ExecQuery( _
    "select * from ServerNetworkProtocol " _
    & "where InstanceName = 'SQLEXPRESS' and ProtocolName = 'Tcp'")

if tcpProtocols.Count = 1 then
    ' set tcpProtocol = tcpProtocols(0)
    ' I wish this worked, but unfortunately 
    ' there's no int-indexed Item property in this type

    ' Doing this instead
    for each tcpProtocol in tcpProtocols
        dim setEnableResult
            setEnableResult = tcpProtocol.SetEnable()
            if setEnableResult <> 0 then 
                Wscript.Echo "Failed!"
            end if
    next
end if

2 - Open the right ports in the firewall

I believe your solution will work, just make sure you specify the right port. I suggest we pick a different port than 1433 and make it a static port SQL Server Express will be listening on. I will be using 3456 in this post, but please pick a different number in the real implementation (I feel that we will see a lot of applications using 3456 soon :-)

3 - Modify TCP/IP properties enable a IP address

We can use WMI again. Since we are using static port 3456, we just need to update two properties in IPAll section: disable dynamic ports and set the listening port to 3456:

set wmiComputer = GetObject( _
    "winmgmts:" _
    & "\\.\root\Microsoft\SqlServer\ComputerManagement10")
set tcpProperties = wmiComputer.ExecQuery( _
    "select * from ServerNetworkProtocolProperty " _
    & "where InstanceName='SQLEXPRESS' and " _
    & "ProtocolName='Tcp' and IPAddressName='IPAll'")

for each tcpProperty in tcpProperties
    dim setValueResult, requestedValue

    if tcpProperty.PropertyName = "TcpPort" then
        requestedValue = "3456"
    elseif tcpProperty.PropertyName ="TcpDynamicPorts" then
        requestedValue = ""
    end if

    setValueResult = tcpProperty.SetStringValue(requestedValue)
    if setValueResult = 0 then 
        Wscript.Echo "" & tcpProperty.PropertyName & " set."
    else
        Wscript.Echo "" & tcpProperty.PropertyName & " failed!"
    end if
next

Note that I didn't have to enable any of the individual addresses to make it work, but if it is required in your case, you should be able to extend this script easily to do so.

Just a reminder that when working with WMI, WBEMTest.exe is your best friend!

4 - Enable mixed mode authentication in sql server

I wish we could use WMI again, but unfortunately this setting is not exposed through WMI. There are two other options:

1. Use LoginMode property of Microsoft.SqlServer.Management.Smo.Server class, as described here.

2. Use LoginMode value in SQL Server registry, as described in this post. Note that by default the SQL Server Express instance is named SQLEXPRESS, so for my SQL Server 2008 R2 Express instance the right registry key was HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS\MSSQLServer.

5 - Change user (sa) default password

You got this one covered.

6 - Finally (connect to the instance)

Since we are using a static port assigned to our SQL Server Express instance, there's no need to use instance name in the server address anymore.

SQLCMD -U sa -P newPassword -S 192.168.0.120,3456

Please let me know if this works for you (fingers crossed!).

Here are a few things you need to do:

1-Download the library if you haven't already done that.

2- Import into Eclipse.

3- Set you project to use the library: Project-> Properties -> Android -> Scroll down to Library section, click Add... and select viewpagerindicator.

4- Now you should be able to import com.viewpagerindicator.TitlePageIndicator.

Now about implementing this without using fragments:

In the sample that comes with viewpagerindicatior, you can see that the library is being used with a ViewPager which has a FragmentPagerAdapter.

But in fact the library itself is Fragment independant. It just needs a ViewPager. So just use a PagerAdapter instead of a FragmentPagerAdapter and you're good to go.

Even though it's not supposedly the correct way, setting the content type to text/html made IE deal with this correctly for me:

return Json(result, "text/html");

Works in all the version that F12 tools gives you in IE9.

According to other answers I am adding the parallel stages scenario:

pipeline {
    agent any
    stages {
        stage('some parallel stage') {
            parallel {
                stage('parallel stage 1') {
                    when {
                      expression { ENV == "something" }
                    }
                    steps {
                        echo 'something'
                    }
                }
                stage('parallel stage 2') {
                    steps {
                        echo 'something'
                    }
                }
            }
        }
    }
}

You could use: Time.now.to_i.

I'd draw the limit for public functions at 5 parameters myself.

IMHO, long parameter lists are only acceptable in private/local helper functions that are only meant to be called from a few specific places in the code. In those cases, you may need to pass a lot of state information along, but readability isn't as big of a concern since only you (or someone who will maintain your code and should understand the fundamentals of your module) have to care about calling that function.

I think that it is so easy to do that. You can just loop over the string from the start and removing zeros until you found a not zero char.

int lastLeadZeroIndex = 0;
for (int i = 0; i < str.length(); i++) {
  char c = str.charAt(i);
  if (c == '0') {
    lastLeadZeroIndex = i;
  } else {
    break;
  }
}

str = str.subString(lastLeadZeroIndex+1, str.length());

If you want to keep the GNU compiler extensions, use -std=gnu++0x rather than -std=c++0x. Here's a quote from the man page:

The compiler can accept several base standards, such as c89 or c++98, and GNU dialects of those standards, such as gnu89 or gnu++98. By specifying a base standard, the compiler will accept all programs following that standard and those using GNU extensions that do not contradict it. For example, -std=c89 turns off certain features of GCC that are incompatible with ISO C90, such as the "asm" and "typeof" keywords, but not other GNU extensions that do not have a meaning in ISO C90, such as omitting the middle term of a "?:" expression. On the other hand, by specifying a GNU dialect of a standard, all features the compiler support are enabled, even when those features change the meaning of the base standard and some strict-conforming programs may be rejected. The particular standard is used by -pedantic to identify which features are GNU extensions given that version of the standard. For example-std=gnu89 -pedantic would warn about C++ style // comments, while -std=gnu99 -pedantic would not.

The issue turned out to be certificate-related. The WCF service called by the console app uses an X509 cert for authentication, which is installed on the servers that this script is hosted and run from.

On other servers, where the same services are consumed, the certificates were configured as follows:

winhttpcertcfg.exe -g -c LOCAL_MACHINE\My -s "certificate-name" -a "NETWORK SERVICE"

As they ran within the context of IIS. However, when the script was being run as it would in production, it's under the context of the user themselves. So, the script needed to be modified to the following:

winhttpcertcfg.exe -g -c LOCAL_MACHINE\My -s "certificate-name" -a "USERS"

Once that change was made, all was well. Thanks to everyone who offered assistance.

Firstly, you should use randrange(0,1000) or randint(0,999), not randint(0,1000). The upper limit of randint is inclusive.

For efficiently, randint is simply a wrapper of randrange which calls random, so you should just use random. Also, use xrange as the argument to sample, not range.

You could use

[a for a in sample(xrange(1000),1000) for _ in range(10000/1000)]

to generate 10,000 numbers in the range using sample 10 times.

(Of course this won't beat NumPy.)

$ python2.7 -m timeit -s 'from random import randrange' '[randrange(1000) for _ in xrange(10000)]'
10 loops, best of 3: 26.1 msec per loop

$ python2.7 -m timeit -s 'from random import sample' '[a%1000 for a in sample(xrange(10000),10000)]'
100 loops, best of 3: 18.4 msec per loop

$ python2.7 -m timeit -s 'from random import random' '[int(1000*random()) for _ in xrange(10000)]' 
100 loops, best of 3: 9.24 msec per loop

$ python2.7 -m timeit -s 'from random import sample' '[a for a in sample(xrange(1000),1000) for _ in range(10000/1000)]'
100 loops, best of 3: 3.79 msec per loop

$ python2.7 -m timeit -s 'from random import shuffle
> def samplefull(x):
>   a = range(x)
>   shuffle(a)
>   return a' '[a for a in samplefull(1000) for _ in xrange(10000/1000)]'
100 loops, best of 3: 3.16 msec per loop

$ python2.7 -m timeit -s 'from numpy.random import randint' 'randint(1000, size=10000)'
1000 loops, best of 3: 363 usec per loop

But since you don't care about the distribution of numbers, why not just use:

range(1000)*(10000/1000)

?

This Perl code edits your original file:

perl -i -ne 's/^\s+//;print' file

The next one makes a backup copy before editing the original file:

perl -i.bak -ne 's/^\s+//;print' file

Notice that Perl borrows heavily from sed (and AWK).

Tested in Android 22.

You can use REINDEX to do that.

Reindex does not attempt to set up the destination index. It does not copy the settings of the source index. You should set up the destination index prior to running a _reindex action, including setting up mappings, shard counts, replicas, etc.

1. First copy the index to a new name

POST /_reindex
{
  "source": {
    "index": "twitter"
  },
  "dest": {
    "index": "new_twitter"
  }
}

2. Now delete the Index

DELETE /twitter

Since it looks like that you only need this structure for the update() function, don't use a structure for this at all, it will only obfuscate your intention behind that construct. You should maybe rethink why you are changing and updating those fields and define separate functions or macros for this "little" changes.

e.g.

#define set_current_route(id, route) update(id, dont_care, dont_care, route)
#define set_route(id, route) update(id, dont_care, route, dont_care)
#define set_backup_route(id, route) update(id, route, dont_care, dont_care)

Or even better write a function for every change case. As you already noticed you don't change every property at the same time, so make it possible to change only one property at a time. This doesn't only improve the readability, but also helps you handling the different cases, e.g. you don't have to check for all the "dont_care" because you know that only the current route is changed.

You can use date filter to convert in date and display in specific format.

In .ts file (typescript):

let dateString = '1968-11-16T00:00:00' 
let newDate = new Date(dateString);

In HTML:

{{dateString |  date:'MM/dd/yyyy'}}

Below are some formats which you can implement :

Backend:

public todayDate = new Date();

HTML :

<select>
<option value=""></option>
<option value="MM/dd/yyyy">[{{todayDate | date:'MM/dd/yyyy'}}]</option>
<option value="EEEE, MMMM d, yyyy">[{{todayDate | date:'EEEE, MMMM d, yyyy'}}]</option>
<option value="EEEE, MMMM d, yyyy h:mm a">[{{todayDate | date:'EEEE, MMMM d, yyyy h:mm a'}}]</option>
<option value="EEEE, MMMM d, yyyy h:mm:ss a">[{{todayDate | date:'EEEE, MMMM d, yyyy h:mm:ss a'}}]</option>
<option value="MM/dd/yyyy h:mm a">[{{todayDate | date:'MM/dd/yyyy h:mm a'}}]</option>
<option value="MM/dd/yyyy h:mm:ss a">[{{todayDate | date:'MM/dd/yyyy h:mm:ss a'}}]</option>
<option value="MMMM d">[{{todayDate | date:'MMMM d'}}]</option>   
<option value="yyyy-MM-ddTHH:mm:ss">[{{todayDate | date:'yyyy-MM-ddTHH:mm:ss'}}]</option>
<option value="h:mm a">[{{todayDate | date:'h:mm a'}}]</option>
<option value="h:mm:ss a">[{{todayDate | date:'h:mm:ss a'}}]</option>      
<option value="EEEE, MMMM d, yyyy hh:mm:ss a">[{{todayDate | date:'EEEE, MMMM d, yyyy hh:mm:ss a'}}]</option>
<option value="MMMM yyyy">[{{todayDate | date:'MMMM yyyy'}}]</option> 
</select>

1. Need to declare a Notification channel with Notification_Channel_ID
2. Build notification with that channel ID. For example,

...
 public static final String NOTIFICATION_CHANNEL_ID = MyLocationService.class.getSimpleName();
...
...
NotificationChannel channel = new NotificationChannel(NOTIFICATION_CHANNEL_ID,
                NOTIFICATION_CHANNEL_ID+"_name",
                NotificationManager.IMPORTANCE_HIGH);

NotificationManager notifManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

notifManager.createNotificationChannel(channel);


NotificationCompat.Builder builder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID)
                .setContentTitle(getString(R.string.app_name))
                .setContentText(getString(R.string.notification_text))
                .setOngoing(true)
                .setContentIntent(broadcastIntent)
                .setSmallIcon(R.drawable.ic_tracker)
                .setPriority(PRIORITY_HIGH)
                .setCategory(Notification.CATEGORY_SERVICE);

        startForeground(1, builder.build());
...

Is something like this what you want to do?

$return_arr = array();

$fetch = mysql_query("SELECT * FROM table"); 

while ($row = mysql_fetch_array($fetch, MYSQL_ASSOC)) {
    $row_array['id'] = $row['id'];
    $row_array['col1'] = $row['col1'];
    $row_array['col2'] = $row['col2'];

    array_push($return_arr,$row_array);
}

echo json_encode($return_arr);

It returns a json string in this format:

[{"id":"1","col1":"col1_value","col2":"col2_value"},{"id":"2","col1":"col1_value","col2":"col2_value"}]

OR something like this:

$year = date('Y');
$month = date('m');

$json_array = array(

//Each array below must be pulled from database
    //1st record
    array(
    'id' => 111,
    'title' => "Event1",
    'start' => "$year-$month-10",
    'url' => "http://yahoo.com/"
),

     //2nd record
     array(
    'id' => 222,
    'title' => "Event2",
    'start' => "$year-$month-20",
    'end' => "$year-$month-22",
    'url' => "http://yahoo.com/"
)

);

echo json_encode($json_array);

Answer by @Calvin Froedge is the shortest answer but have an issue also mentioned by @kizu. Due to inconsistent width of the div the div will flick on hover. To solve this issue add minus margin to the right on hover

#div { 
     overflow:hidden;
     height:whatever px; 
}
#div:hover { 
     overflow-y:scroll; 
     margin-right: -15px; // adjust according to scrollbar width  
}

I think, as always, it depends ...

REST has the huge advantage of widespread public support and this means lots of tools and books. If you need to make an API that is used by a large number of consumers from different organisations then it is the way to go for only one reason: it is popular. As a protocol it is of course a total failure since there are too many completely different ways to map a command to a URL/verb/response.

Therefore, when you write a single page web app that needs to talk to a backend then I think REST is way too complex. In this situation you do not have to worry about long term compatibility since the app and API can evolved together.

I once started with REST for a single page web app but the fine grained commands between the web app and the server quickly drove me crazy. Should I encode it as a path parameter? In the body? A query parameter? A header? After the URL/Verb/Response design I then had to code this mess in Javascript, the decoder in Java and then call the actual method. Although there are lots of tools for it, it is really tricky to not get any HTTP semantics in your domain code, which is really bad practice. (Cohesion)

Try making a Swagger/OpenAPI file for a medium complex site and compare that to a single Java interface that describes the remote procedures in that file. The complexity increase is staggering.

I therefore switched from REST to JSON-RPC for the single page webapp. aI developed a tiny library that encoded a Java interface on the server and shipped it to the browser. In the browser this created a proxy for the application code that returned a promise for each function.

Again, REST has its place just because it is famous and therefore well supported. It is also important to recognise the underlying stateless resources philosophy and the hierarchical model. However, these principles can just as easy be used in an RPC model. JSON RPC works over HTTP so it has the same advantages of REST in this area. The difference is that when you inevitably run into these functions that do not map well to these principles you're not forced to do a lot of unnecessary work.

Came across this one today, while studying https://www.coursera.org/course/bioinformatics

DPCHANGE(money, coins)
 MinNumCoins(0) ? 0
 for m ? 1 to money
        MinNumCoins(m) ? 8
        for i ? 1 to |coins|
            if m = coini
                if MinNumCoins(m - coini) + 1 < MinNumCoins(m)
                    MinNumCoins(m) ? MinNumCoins(m - coini) + 1
    output MinNumCoins(money)

Takes a comma-separated string of denominations available, and the target amount.

C# implementation:

    public static void DPCHANGE(int val, string denoms)
    {
        int[] idenoms = Array.ConvertAll(denoms.Split(','), int.Parse);
        Array.Sort(idenoms);
        int[] minNumCoins = new int[val + 1];

        minNumCoins[0] = 0;
        for (int m = 1; m <= val; m++)
        {
            minNumCoins[m] = Int32.MaxValue - 1;
            for (int i = 1; i <= idenoms.Count() - 1; i++)
            {
                if (m >= idenoms[i])
                {
                    if (minNumCoins[m - idenoms[i]] + 1 < minNumCoins[m])
                    {
                        minNumCoins[m] = minNumCoins[m - idenoms[i]] + 1;
                    }
                }
            }
        }
    }

gradlew is a wrapper(w - character) that uses gradle.

Under the hood gradlew performs three main things:

• Download and install the correct gradle version
• Parse the arguments
• Call a gradle task

Using Gradle Wrapper we can distribute/share a project to everybody to use the same version and Gradle's functionality(compile, build, install...) even if it has not been installed.

To create a wrapper run:

gradle wrapper

This command generate:

gradle-wrapper.properties will contain the information about the Gradle distribution

*./ Is used on Unix to specify the current directory

For naming template parameters, typename and class are equivalent. §14.1.2:

There is no semantic difference between class and typename in a template-parameter.

typename however is possible in another context when using templates - to hint at the compiler that you are referring to a dependent type. §14.6.2:

A name used in a template declaration or definition and that is dependent on a template-parameter is assumed not to name a type unless the applicable name lookup finds a type name or the name is qualified by the keyword typename.

Example:

typename some_template<T>::some_type

Without typename the compiler can't tell in general whether you are referring to a type or not.

Sounds like you need to install the devel package for zlib, probably want to do something like sudo apt-get install zlib1g-dev (I don't use ubuntu so you'll want to double-check the package). Instead of using python-brew you might want to consider just compiling by hand, it's not very hard. Just download the source, and configure, make, make install. You'll want to at least set --prefix to somewhere, so it'll get installed where you want.

./configure --prefix=/opt/python2.7 + other options
make
make install

You can check what configuration options are available with ./configure --help and see what your system python was compiled with by doing:

python -c "import sysconfig; print sysconfig.get_config_var('CONFIG_ARGS')"

The key is to make sure you have the development packages installed for your system, so that Python will be able to build the zlib, sqlite3, etc modules. The python docs cover the build process in more detail: http://docs.python.org/using/unix.html#building-python.

Please take note before down voting, this solution is for Gimp using a graphical interface, and not for ImageMagick using a command line, but it worked perfectly fine for me as an alternative, and that is why I found it needful to share here.

Follow these simple steps to extract images in any format from PDF documents

1. Download GIMP Image Manipulation Program
2. Open the Program after installation
3. Open the PDF document that you want to extract Images
4. Select only the pages of the PDF document that you would want to extract images from. N/B: If you need only the cover images, select only the first page.
5. Click open after selecting the pages that you want to extract images from
6. Click on File menu when GIMP when the pages open
7. Select Export as in the File menu
8. Select your preferred file type by extension (say png) below the dialog box that pops up.
9. Click on Export to export your image to your desired location.
10. You can then check your file explorer for the exported image.

That's all.

I hope this helps

If the stashed files need to merge with the current version so use the previous ways using diff. Otherwise you might use git pop for unstashing them, git add fileWantToKeep for staging your file, and do a git stash save --keep-index, for stashing everything except what is on stage. Remember that the difference of this way with the previous ones is that it "pops" the file from stash. The previous answers keep it git checkout stash@{0} -- <filename> so it goes according to your needs.

you can use:

$window.open(url, windowName, attributes);

In this line ...

if (*message == "\0") {

... as you can see in the warning ...

warning: comparison between pointer and integer
      ('int' and 'char *')

... you are actually comparing an int with a char *, or more specifically, an int with an address to a char.

To fix this, use one of the following:

if(*message == '\0') ...
if(message[0] == '\0') ...
if(!*message) ...

On a side note, if you'd like to compare strings you should use strcmp or strncmp, found in string.h.

I was able to fix this with the following:

First, exit Eclipse. Then temporarily move the following .projects folder to a safe location:

mv .metadata\.plugins\org.eclipse.core.resources\.projects projects

Start and exit Eclipse, then move the .projects folder back to where it was originally:

mv projects .metadata\.plugins\org.eclipse.core.resources\.projects

Use at your own risk, of course.

In addition, Win10 gives you an option to open git bash from your working directory by right-clicking on your folder and selecting GitBash here.

I could never get the Windows 7 SDK to install either, and it suggested I remove the latest SDK and Visual Studio 2012 Express. That didn't work.

There was also something about .NET 3.5. I installed the Server 2008 SDK with .NET 3.5, uninstalled Visual Studio 2010 redistributables and made sure redistributables were unchecked in the installation options.

Also, you need the .NET 4 framework already installed, which you can download from Microsoft's site. Then it worked.

Looks like you might want the ISO format so that you can retain the timezone.

var dateTime = new Date(1370001284000);
dateTime.toISOString(); // Returns "2013-05-31T11:54:44.000Z"

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString

If you run npm config edit, you'll get an editor showing the current configuration, and also a list of options and their default values.

But I don't think there's a 'reset' command.

I used a BoxLayout and set its second parameter as BoxLayout.Y_AXIS and it worked for me:

panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));

@tennisgent's solution is great. However, I think is a little limited.

Modularity and Encapsulation in Angular goes beyond routes. Based on the way the web is moving towards component-based development, it is important to apply this in directives as well.

As you already know, in Angular we can include templates (structure) and controllers (behavior) in pages and components. AngularCSS enables the last missing piece: attaching stylesheets (presentation).

For a full solution I suggest using AngularCSS.

1. Supports Angular's ngRoute, UI Router, directives, controllers and services.
2. Doesn't required to have ng-app in the <html> tag. This is important when you have multiple apps running on the same page
3. You can customize where the stylesheets are injected: head, body, custom selector, etc...
4. Supports preloading, persisting and cache busting
5. Supports media queries and optimizes page load via matchMedia API

https://github.com/door3/angular-css

Here are some examples:

Routes

  $routeProvider
    .when('/page1', {
      templateUrl: 'page1/page1.html',
      controller: 'page1Ctrl',
      /* Now you can bind css to routes */
      css: 'page1/page1.css'
    })
    .when('/page2', {
      templateUrl: 'page2/page2.html',
      controller: 'page2Ctrl',
      /* You can also enable features like bust cache, persist and preload */
      css: {
        href: 'page2/page2.css',
        bustCache: true
      }
    })
    .when('/page3', {
      templateUrl: 'page3/page3.html',
      controller: 'page3Ctrl',
      /* This is how you can include multiple stylesheets */
      css: ['page3/page3.css','page3/page3-2.css']
    })
    .when('/page4', {
      templateUrl: 'page4/page4.html',
      controller: 'page4Ctrl',
      css: [
        {
          href: 'page4/page4.css',
          persist: true
        }, {
          href: 'page4/page4.mobile.css',
          /* Media Query support via window.matchMedia API
           * This will only add the stylesheet if the breakpoint matches */
          media: 'screen and (max-width : 768px)'
        }, {
          href: 'page4/page4.print.css',
          media: 'print'
        }
      ]
    });

Directives

myApp.directive('myDirective', function () {
  return {
    restrict: 'E',
    templateUrl: 'my-directive/my-directive.html',
    css: 'my-directive/my-directive.css'
  }
});

Additionally, you can use the $css service for edge cases:

myApp.controller('pageCtrl', function ($scope, $css) {

  // Binds stylesheet(s) to scope create/destroy events (recommended over add/remove)
  $css.bind({ 
    href: 'my-page/my-page.css'
  }, $scope);

  // Simply add stylesheet(s)
  $css.add('my-page/my-page.css');

  // Simply remove stylesheet(s)
  $css.remove(['my-page/my-page.css','my-page/my-page2.css']);

  // Remove all stylesheets
  $css.removeAll();

});

Quicksort is the fastest sorting algorithm in practice but has a number of pathological cases that can make it perform as badly as O(n2).

Heapsort is guaranteed to run in O(n*ln(n)) and requires only finite additional storage. But there are many citations of real world tests which show that heapsort is significantly slower than quicksort on average.

If you want to add wsdl reference in .Net Core project, there is no "Add web reference" option.

To add the wsdl reference go to Solution Explorer, right-click on the References project item and then click on the Add Connected Service option.

Then click 'Microsoft WCF Web Service Reference':

Enter the file path into URI text box and import the WSDL:

It will generate a simple, very basic WCF client and you to use it something like this:

YourServiceClient client = new YourServiceClient();
client.DoSomething();

As I was researching this I thought it would be nice to modify the BETWEEN solution to show an example for a particular non-static/string date, but rather a variable date, or today's such as CURRENT_DATE(). This WILL use the index on the log_timestamp column.

SELECT *
FROM some_table
WHERE
    log_timestamp
    BETWEEN 
        timestamp(CURRENT_DATE()) 
    AND # Adds 23.9999999 HRS of seconds to the current date
        timestamp(DATE_ADD(CURRENT_DATE(), INTERVAL '86399.999999' SECOND_MICROSECOND));

I did the seconds/microseconds to avoid the 12AM case on the next day. However, you could also do `INTERVAL '1 DAY' via comparison operators for a more reader-friendly non-BETWEEN approach:

SELECT *
FROM some_table
WHERE
    log_timestamp >= timestamp(CURRENT_DATE()) AND
    log_timestamp < timestamp(DATE_ADD(CURRENT_DATE(), INTERVAL 1 DAY));

Both of these approaches will use the index and should perform MUCH faster. Both seem to be equally as fast.

I wrote a custom hook that will run a function once before first render.

useBeforeFirstRender.js

import { useState, useEffect } from 'react'

export default (fun) => {
  const [hasRendered, setHasRendered] = useState(false)

  useEffect(() => setHasRendered(true), [hasRendered])

  if (!hasRendered) {
    fun()
  }
}

Usage:

import React, { useEffect } from 'react'
import useBeforeFirstRender from '../hooks/useBeforeFirstRender'


export default () => { 
  useBeforeFirstRender(() => {
    console.log('Do stuff here')
  })

  return (
    <div>
      My component
    </div>
  )
}

From here:

ArrayList is internally backed by Array in Java, any resize operation in ArrayList will slow down performance as it involves creating new Array and copying content from old array to new array.

In terms of performance Array and ArrayList provides similar performance in terms of constant time for adding or getting element if you know index. Though automatic resize of ArrayList may slow down insertion a bit Both Array and ArrayList is core concept of Java and any serious Java programmer must be familiar with these differences between Array and ArrayList or in more general Array vs List.

404 is just the HTTP response code. On top of that, you can provide a response body and/or other headers with a more meaningful error message that developers will see.

Using Roslyn, you can dynamically create a class which inherits from an interface (or abstract class).

I use the following to create concrete classes from abstract classes.

In this example, AAnimal is an abstract class.

var personClass = typeof(AAnimal).CreateSubclass("Person");

Then you can instantiate some objects:

var person1 = Activator.CreateInstance(personClass);
var person2 = Activator.CreateInstance(personClass);

Without a doubt this won't work for every case, but it should be enough to get you started:

using Microsoft.CodeAnalysis;
using Microsoft.CodeAnalysis.CSharp;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Reflection;

namespace Publisher
{
    public static class Extensions
    {
        public static Type CreateSubclass(this Type baseType, string newClassName, string newNamespace = "Magic")
        {

Save function:

already do what you want...

Laravel code:

    // If the model already exists in the database we can just update our record
    // that is already in this database using the current IDs in this "where"
    // clause to only update this model. Otherwise, we'll just insert them.
    if ($this->exists)
    {
        $saved = $this->performUpdate($query);
    }

    // If the model is brand new, we'll insert it into our database and set the
    // ID attribute on the model to the value of the newly inserted row's ID
    // which is typically an auto-increment value managed by the database.
    else
    {
        $saved = $this->performInsert($query);
    }

You can use the method match() to extract a substring between two strings. Try the following code:

var str = "My cow always gives milk";
var subStr = str.match("cow(.*)milk");
console.log(subStr[1]);

Output:

always gives

See a complete example here : How to find sub-string between two strings.

1. = 0 means that a function is pure virtual and you cannot instantiate an object from this class. You need to derive from it and implement this method
2. = delete means that the compiler will not generate those constructors for you. AFAIK this is only allowed on copy constructor and assignment operator. But I am not too good at the upcoming standard.

For POI 3.17 this worked for me

switch (cellh.getCellTypeEnum()) {
    case FORMULA: 
        if (cellh.getCellFormula().indexOf("LINEST") >= 0) {
            value = Double.toString(cellh.getNumericCellValue());
        } else {
            value = XLS_getDataFromCellValue(evaluator.evaluate(cellh));
        }
        break;
    case NUMERIC:
        value = Double.toString(cellh.getNumericCellValue());
        break;
    case STRING:
        value = cellh.getStringCellValue();
        break;
    case BOOLEAN:
        if(cellh.getBooleanCellValue()){
            value = "true";
        } else {
            value = "false";
        }
        break;
    default:
        value = "";
        break;
}

i found i had to do something akin to

=(countifs (A1:A196,"yes", j1:j196, "agree") + (countifs (A1:A196,"no", j1:j196, "agree"))

You can set it on the command line via JVM parameters:

java -Duser.country=CA -Duser.language=fr ... com.x.Main

You cannot directly use a SQL statement in a PL/SQL expression:

SQL> begin
  2     if (select count(*) from dual) >= 1 then
  3        null;
  4     end if;
  5  end;
  6  /
        if (select count(*) from dual) >= 1 then
            *
ERROR at line 2:
ORA-06550: line 2, column 6:
PLS-00103: Encountered the symbol "SELECT" when expecting one of the following:
...
...

You must use a variable instead:

SQL> set serveroutput on
SQL>
SQL> declare
  2     v_count number;
  3  begin
  4     select count(*) into v_count from dual;
  5
  6     if v_count >= 1 then
  7             dbms_output.put_line('Pass');
  8     end if;
  9  end;
 10  /
Pass

PL/SQL procedure successfully completed.

Of course, you may be able to do the whole thing in SQL:

update my_table
set x = y
where (select count(*) from other_table) >= 1;

It's difficult to prove that something is not possible. Other than the simple test case above, you can look at the syntax diagram for the IF statement; you won't see a SELECT statement in any of the branches.

Run the following immediately after the dialog is called in the Ajax:

    $(".ui-dialog-titlebar").hide();
    $(".ui-dialog").addClass("customclass");

This applies just to the dialog that is opened, so it can be changed for each one used.

(This quick answer is based on another response on Stack Overflow.)

According to the book PHP and MySQL for Dynamic Web Sites (4th edition)

Example:

$r = mysqli_query($dbc, $q);

For simple queries like INSERT, UPDATE, DELETE, etc. (which do not return records), the $r variable—short for result—will be either TRUE or FALSE, depending upon whether the query executed successfully.

Keep in mind that “executed successfully” means that it ran without error; it doesn’t mean that the query’s execution necessarily had the desired result; you’ll need to test for that.

Then how to test?

While the mysqli_num_rows() function will return the number of rows generated by a SELECT query, mysqli_affected_rows() returns the number of rows affected by an INSERT, UPDATE, or DELETE query. It’s used like so:

$num = mysqli_affected_rows($dbc);

Unlike mysqli_num_rows(), the one argument the function takes is the database connection ($dbc), not the results of the previous query ($r).

Here is a simple AppCompatActivity extension function, which closes opened Dialog Fragment:

fun AppCompatActivity.whenDialogOpenDismiss(
    tag: String
) {
    supportFragmentManager.findFragmentByTag(tag)?.let { 
        if(it is DialogFragment) it.dismiss() }
}

Of course you can call it from any activity directly. If you need to call it from a Fragment just make the same extension function about Fragment class

Basically you need following things to make location detector android app

• Location Listener, which detect current location
• Marker to add and animate when person moves
• Polyline to add path on person's movement
• Services for sending and receiving location
• Rest API / Firebase Realtime Database to store and fetch locations

Now if you write each of these module yourself then it needs much time and efforts. So it would be better to use ready resources that are being maintained already.

Using all these resources, you will be able to create an flawless android location detection app.

1. Location Listening

You will first need to listen for current location of user. You can use any of below libraries to quick start.

Google Play Location Samples

This library provide last known location, location updates

Location Manager

With this library you just need to provide a Configuration object with your requirements, and you will receive a location or a fail reason with all the stuff are described above handled.

Live Location Sharing

Use this open source repo of the Hypertrack Live app to build live location sharing experience within your app within a few hours. HyperTrack Live app helps you share your Live Location with friends and family through your favorite messaging app when you are on the way to meet up. HyperTrack Live uses HyperTrack APIs and SDKs.

2. Markers Library

Google Maps Android API utility library

• Marker clustering — handles the display of a large number of points
• Heat maps — display a large number of points as a heat map
• IconGenerator — display text on your Markers
• Poly decoding and encoding — compact encoding for paths, interoperability with Maps API web services
• Spherical geometry — for example: computeDistance, computeHeading, computeArea
• KML — displays KML data
• GeoJSON — displays and styles GeoJSON data

3. Polyline Libraries

DrawRouteMaps

If you want to add route maps feature in your apps you can use DrawRouteMaps to make you work more easier. This is lib will help you to draw route maps between two point LatLng.

trail-android

Simple, smooth animation for route / polylines on google maps using projections. (WIP)

Google-Directions-Android

This project allows you to calculate the direction between two locations and display the route on a Google Map using the Google Directions API.

A map demo app for quick start with maps

@arad good point. In fact I just found this extension method (.NET 5.0):

PostAsJsonAsync<TValue>(HttpClient, String, TValue, CancellationToken)

from https://docs.microsoft.com/en-us/dotnet/api/system.net.http.json.httpclientjsonextensions.postasjsonasync?view=net-5.0

So one can now:

var data = new { foo = "Hello"; bar = 42; };
var response = await _Client.PostAsJsonAsync(_Uri, data, cancellationToken);

I thought I'd share a situation where my team decided to include .c files. Our archicture largely consists of modules that are decoupled through a message system. These message handlers are public, and call many local static worker functions to do their work. The problem came about when trying to get coverage for our unit test cases, as the only way to exercise this private implementation code was indirectly through the public message interface. With some worker functions knee-deep in the stack, this turned out to be a nightmare to achieve proper coverage.

Including the .c files gave us a way to reach the cog in the machine we were interesting in testing.

An other example would be on the "created_on" column where you want to let the database handle the date creation

Do it in this format:

classmehodisin.methodname();

For example:

MyClass1.clearscreen();

I hope this helped.` Note:The method must be static.

# Make sure only root can run our script
if [ "$(id -u)" != "0" ]; then
   echo "This script must be run as root" 1>&2
   exit 1

JAR File Manifest Attributes for Security

The JAR file manifest contains information about the contents of the JAR file, including security and configuration information.

Add the attributes to the manifest before the JAR file is signed.
See Modifying a Manifest File in the Java Tutorial for information on adding attributes to the JAR manifest file.

Permissions Attribute

The Permissions attribute is used to verify that the permissions level requested by the RIA when it runs matches the permissions level that was set when the JAR file was created.

Use this attribute to help prevent someone from re-deploying an application that is signed with your certificate and running it at a different privilege level. Set this attribute to one of the following values:

• sandbox - runs in the security sandbox and does not require additional permissions.

• all-permissions - requires access to the user's system resources.

Changes to Security Slider:

The following changes to Security Slider were included in this release(7u51):

• Block Self-Signed and Unsigned applets on High Security Setting
• Require Permissions Attribute for High Security Setting
• Warn users of missing Permissions Attributes for Medium Security Setting

For more information, see Java Control Panel documentation.

I got the same error and i fixed it by looking at the solution from this site:

http://trac.macports.org/ticket/40476.

SO did you got any error after running './configure' ? Maybe something about lacking tclConfig.sh. If so, instead of running './configure', you have to search for the tclConfigure.sh first and then put it in the command, in my case, its located in /usr/lib/. And then run: './configure ----with-tcl=/usr/lib --with-tclinclude=/usr/include'

if by .add you mean .append, then the result is the same if #myDiv is empty.

is the performance the same? dont know.

.html(x) ends up doing the same thing as .empty().append(x)

You can use $lookup ( multiple ) to get the records from multiple collections:

Example:

If you have more collections ( I have 3 collections for demo here, you can have more than 3 ). and I want to get the data from 3 collections in single object:

The collection are as:

db.doc1.find().pretty();

{
    "_id" : ObjectId("5901a4c63541b7d5d3293766"),
    "firstName" : "shubham",
    "lastName" : "verma"
}

db.doc2.find().pretty();

{
    "_id" : ObjectId("5901a5f83541b7d5d3293768"),
    "userId" : ObjectId("5901a4c63541b7d5d3293766"),
    "address" : "Gurgaon",
    "mob" : "9876543211"
}

db.doc3.find().pretty();

{
    "_id" : ObjectId("5901b0f6d318b072ceea44fb"),
    "userId" : ObjectId("5901a4c63541b7d5d3293766"),
    "fbURLs" : "http://www.facebook.com",
    "twitterURLs" : "http://www.twitter.com"
}

Now your query will be as below:

db.doc1.aggregate([
    { $match: { _id: ObjectId("5901a4c63541b7d5d3293766") } },
    {
        $lookup:
        {
            from: "doc2",
            localField: "_id",
            foreignField: "userId",
            as: "address"
        }
    },
    {
        $unwind: "$address"
    },
    {
        $project: {
            __v: 0,
            "address.__v": 0,
            "address._id": 0,
            "address.userId": 0,
            "address.mob": 0
        }
    },
    {
        $lookup:
        {
            from: "doc3",
            localField: "_id",
            foreignField: "userId",
            as: "social"
        }
    },
    {
        $unwind: "$social"
    },

  {   
    $project: {      
           __v: 0,      
           "social.__v": 0,      
           "social._id": 0,      
           "social.userId": 0
       }
 }

]).pretty();

Then Your result will be:

{
    "_id" : ObjectId("5901a4c63541b7d5d3293766"),
    "firstName" : "shubham",
    "lastName" : "verma",

    "address" : {
        "address" : "Gurgaon"
    },
    "social" : {
        "fbURLs" : "http://www.facebook.com",
        "twitterURLs" : "http://www.twitter.com"
    }
}

If you want all records from each collections then you should remove below line from query:

{
            $project: {
                __v: 0,
                "address.__v": 0,
                "address._id": 0,
                "address.userId": 0,
                "address.mob": 0
            }
        }

{   
        $project: {      
               "social.__v": 0,      
               "social._id": 0,      
               "social.userId": 0
           }
     }

After removing above code you will get total record as:

{
    "_id" : ObjectId("5901a4c63541b7d5d3293766"),
    "firstName" : "shubham",
    "lastName" : "verma",
    "address" : {
        "_id" : ObjectId("5901a5f83541b7d5d3293768"),
        "userId" : ObjectId("5901a4c63541b7d5d3293766"),
        "address" : "Gurgaon",
        "mob" : "9876543211"
    },
    "social" : {
        "_id" : ObjectId("5901b0f6d318b072ceea44fb"),
        "userId" : ObjectId("5901a4c63541b7d5d3293766"),
        "fbURLs" : "http://www.facebook.com",
        "twitterURLs" : "http://www.twitter.com"
    }
}

var listTrue = ['a', 'a', 'a', 'a'];
var listFalse = ['a', 'a', 'a', 'ab'];

function areWeTheSame(list) { 
    var sample = list[0];
    return !(list.some(function(item) {
        return !(item == sample);
    }));
}

There are a number of steps you have to go through to create an installer and it varies for each Operating System. For Example:

• on Mac OS X you need to create a .pkg, there are instructions on how to do that here: https://coolaj86.com/articles/how-to-create-an-osx-pkg-installer.html
• on Ubuntu Linux you need to create a .deb, there are instruction on how to do that here: https://coolaj86.com/articles/how-to-create-a-debian-installer.html
• on Microsoft Windows you need to create a .exe or .msi, there are instruction on how do that using the innosetup installer here: https://coolaj86.com/articles/how-to-create-an-innosetup-installer.html

By default mesh will color surface values based on the (default) jet colormap (i.e. hot is higher). You can additionally use surf for filled surface patches and set the 'EdgeColor' property to 'None' (so the patch edges are non-visible).

[X,Y] = meshgrid(-8:.5:8);
R = sqrt(X.^2 + Y.^2) + eps;
Z = sin(R)./R;

% surface in 3D
figure;
surf(Z,'EdgeColor','None');

2D map: You can get a 2D map by switching the view property of the figure

% 2D map using view
figure;
surf(Z,'EdgeColor','None');
view(2);    

... or treating the values in Z as a matrix, viewing it as a scaled image using imagesc and selecting an appropriate colormap.

% using imagesc to view just Z
figure;
imagesc(Z); 
colormap jet; 

The color pallet of the map is controlled by colormap(map), where map can be custom or any of the built-in colormaps provided by MATLAB:

Update/Refining the map: Several design options on the map (resolution, smoothing, axis etc.) can be controlled by the regular MATLAB options. As @Floris points out, here is a smoothed, equal-axis, no-axis labels maps, adapted to this example:

figure;
surf(X, Y, Z,'EdgeColor', 'None', 'facecolor', 'interp');
view(2);
axis equal; 
axis off;

First convert your image to Base64 (encode to Base64). You can do it online or with a PHP script.

After converting you will get the result as

As Jim Garrison said in the comment, no obvious reason why you'd make a one-element list out of drug.upper() (which implies drug is a string).

But that's not your error, as your function medications_minimum3() doesn't even use the second argument (something you should fix).

TypeError: unhashable type: 'list' usually means that you are trying to use a list as a hash argument (like for accessing a dictionary). I'd look for the error in counter[row[11]]+=1 -- are you sure that row[11] is of the right type? Sounds to me it might be a list.

Change your code to.

<?php
$sqlupdate1 = "UPDATE table SET commodity_quantity=".$qty."WHERE user=".$rows['user'];
?>

There was syntax error in your query.

Microsoft SQL Date Formats

CONVERT(DateTime, DateField, 104)

In Version 4.0.2 slightly different Just in processResults and in result :

    processResults: function (data) {
        return {
            results: $.map(data.items, function (item) {
                return {
                    text: item.tag_value,
                    id: item.tag_id
                }
            })
        };
    }

You must add data.items in result. items is Json name :

{
  "items": [
    {"id": 1,"name": "Tetris","full_name": "s9xie/hed"},
    {"id": 2,"name": "Tetrisf","full_name": "s9xie/hed"}
  ]
}

My answer seems like less code and it works for me:

    class Nose {
      constructor() {
        this.booger = 'ready'; 
      }
      
      pick() {
        console.log('pick your nose')
      } 
    }
    
    class Ear {
      constructor() {
        this.wax = 'ready'; 
      }
      
      dig() {
        console.log('dig in your ear')
      } 
    }
    
    class Gross extends Classes([Nose,Ear]) {
      constructor() {
        super();
        this.gross = true;
      }
    }
    
    function Classes(bases) {
      class Bases {
        constructor() {
          bases.forEach(base => Object.assign(this, new base()));
        }
      }
      bases.forEach(base => {
        Object.getOwnPropertyNames(base.prototype)
        .filter(prop => prop != 'constructor')
        .forEach(prop => Bases.prototype[prop] = base.prototype[prop])
      })
      return Bases;
    }

    
    // test it
    
    var grossMan = new Gross();
    grossMan.pick(); // eww
    grossMan.dig();  // yuck!

Solution September 2020

Using Kotlin

fun File.getMimeType(context: Context): String? {
    if (this.isDirectory) {
        return null
    }

    fun fallbackMimeType(uri: Uri): String? {
        return if (uri.scheme == ContentResolver.SCHEME_CONTENT) {
            context.contentResolver.getType(uri)
        } else {
            val extension = MimeTypeMap.getFileExtensionFromUrl(uri.toString())
            MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension.toLowerCase(Locale.getDefault()))
        }
    }

    fun catchUrlMimeType(): String? {
        val uri = Uri.fromFile(this)

        return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            val path = Paths.get(uri.toString())
            try {
                Files.probeContentType(path) ?: fallbackMimeType(uri)
            } catch (ignored: IOException) {
                fallbackMimeType(uri)
            }
        } else {
            fallbackMimeType(uri)
        }
    }

    return try {
        URLConnection.guessContentTypeFromStream(this.inputStream()) ?: catchUrlMimeType()
    } catch (ignored: IOException) {
        catchUrlMimeType()
    }
}

That seems like the best option as it combines the previous answers.

First it tries to get the type using URLConnection.guessContentTypeFromStream but if this fails or returns null it tries to get the mimetype on Android O and above using

java.nio.file.Files
java.nio.file.Paths

Otherwise if the Android Version is below O or the method fails it returns the type using ContentResolver and MimeTypeMap

Some of the previously mentioned solutions did not work for me, even though they are of more general usage. Alternatively I've found this one that did the job on window resize:

$(window).bind('resize', function(e){
    window.resizeEvt;
    $(window).resize(function(){
        clearTimeout(window.resizeEvt);
        window.resizeEvt = setTimeout(function(){
        //code to do after window is resized
        }, 250);
    });
});

If you know the package name, then this works without using a try-catch block or iterating through a bunch of packages:

public static boolean isPackageInstalled(Context context, String packageName) {
    final PackageManager packageManager = context.getPackageManager();
    Intent intent = packageManager.getLaunchIntentForPackage(packageName);
    if (intent == null) {
        return false;
    }
    List<ResolveInfo> list = packageManager.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
    return !list.isEmpty();
}

One technique is to create a copy of the collection you want to modify, change the copy as needed, then replace the original collection with the copy at the end.

var vals = new Array( 2, 3, 5, 8 );
select_disable_options('add_reklamaciq_reason',vals);
select_disable_options('add_reklamaciq_reason');

function select_disable_options(selectid,vals){
  var selected = false ;
  $('#'+selectid+' option').removeAttr('selected');
  $('#'+selectid+' option').each(function(i,elem){
       var elid = parseInt($(elem).attr('value'));
       if(vals){
           if(vals.indexOf(elid) != -1){
               $(elem).removeAttr('disabled');
               if(selected == false){
                   $(elem).attr('selected','selected');
                   selected = true ; 
               }
           }else{
               $(elem).attr('disabled','disabled'); 
           }
       }else{
            $(elem).removeAttr('disabled');
       }
  });   
}

Here with JQ .. if anybody search it

can you check your config file under ~/.aws/config- you might have an invalid section called [myname], something like this (this is an example)

[default]
region=us-west-2
output=json

[myname]
region=us-east-1
output=text

Just remove the [myname] section (including all content for this profile) and you will be fine to run aws cli again

I think you need to do is to transform your data from object not to JSON string, but to url params.

From Ben Nadel's blog.

By default, the $http service will transform the outgoing request by serializing the data as JSON and then posting it with the content- type, "application/json". When we want to post the value as a FORM post, we need to change the serialization algorithm and post the data with the content-type, "application/x-www-form-urlencoded".

Example from here.

$http({
    method: 'POST',
    url: url,
    headers: {'Content-Type': 'application/x-www-form-urlencoded'},
    transformRequest: function(obj) {
        var str = [];
        for(var p in obj)
        str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));
        return str.join("&");
    },
    data: {username: $scope.userName, password: $scope.password}
}).then(function () {});

UPDATE

To use new services added with AngularJS V1.4, see

• URL-encoding variables using only AngularJS services

var newDate = new Date(this.oldDate); I was passing oldDate to function and generating newDate from this.oldDate, but it was changing this.oldDate also.So i used that solution and it worked.

        printf("Enter the dirctory name: ");

You are importing from package "sub". start.py is not itself in a package even if there is a __init__.py present.

You would need to start your program from one directory over parent.py:

./start.py

./pkg/__init__.py
./pkg/parent.py
./pkg/sub/__init__.py
./pkg/sub/relative.py

With start.py:

import pkg.sub.relative

Now pkg is the top level package and your relative import should work.

If you want to stick with your current layout you can just use import parent. Because you use start.py to launch your interpreter, the directory where start.py is located is in your python path. parent.py lives there as a separate module.

You can also safely delete the top level __init__.py, if you don't import anything into a script further up the directory tree.

You need to test the character set on input since responses can come coded with different encodings.

I force all content been sent into UTF-8 by doing detection and translation using the following function:

function fixRequestCharset()
{
  $ref = array(&$_GET, &$_POST, &$_REQUEST);
  foreach ($ref as &$var)
  {
    foreach ($var as $key => $val)
    {
      $encoding = mb_detect_encoding($var[$key], mb_detect_order(), true);
      if (!$encoding)
        continue;
      if (strcasecmp($encoding, 'UTF-8') != 0)
      {
        $encoding = iconv($encoding, 'UTF-8', $var[$key]);
        if ($encoding === false)
          continue;
        $var[$key] = $encoding;
      }
    }
  }
}

That routine will turn all PHP variables that come from the remote host into UTF-8.

Or ignore the value if the encoding could not be detected or converted.

You can customize it to your needs.

Just invoke it before using the variables.

1. Proxies are classes that are created and loaded at runtime. There is no source code for these classes. I know that you are wondering how you can make them do something if there is no code for them. The answer is that when you create them, you specify an object that implements InvocationHandler, which defines a method that is invoked when a proxy method is invoked.

2. You create them by using the call

   Proxy.newProxyInstance(classLoader, interfaces, invocationHandler)
   

   The arguments are:

   1. classLoader. Once the class is generated, it is loaded with this class loader.
   2. interfaces. An array of class objects that must all be interfaces. The resulting proxy implements all of these interfaces.
   3. invocationHandler. This is how your proxy knows what to do when a method is invoked. It is an object that implements InvocationHandler. When a method from any of the supported interfaces, or hashCode, equals, or toString, is invoked, the method invoke is invoked on the handler, passing the Method object for the method to be invoked and the arguments passed.

   For more on this, see the documentation for the Proxy class.

3. Every implementation of a JVM after version 1.3 must support these. They are loaded into the internal data structures of the JVM in an implementation-specific way, but it is guaranteed to work.

You may change the pg_hba.conf and then reload the postgresql. something in the pg_hba.conf may be like below:

# "local" is for Unix domain socket connections only
local   all             all                                     trust
# IPv4 local connections:
host    all             all             127.0.0.1/32            trust

then you change your user to postgresql, you may login successfully.

su postgresql

There is no function overloading in Python, meaning that you can't have multiple functions with the same name but different arguments.

In your code example, you're not overloading __init__(). What happens is that the second definition rebinds the name __init__ to the new method, rendering the first method inaccessible.

As to your general question about constructors, Wikipedia is a good starting point. For Python-specific stuff, I highly recommend the Python docs.

Simply in one line:

var result = table.First(x => x.Status == table.Max(y => y.Status));

Notice that there are two action. the inner action is for finding the max value, the outer action is for get the desired object.

100% Solved. While Installing make sure you are connected to Internet. If already installed anaconda, open the anaconda command prompt and type following command:

conda install -c anaconda anaconda-navigator
(internet connection is required)

Note: In some cases restarting may solve the issue of navigator.

To extend the previous answer even more, like Ankit was saying, for complex objects you need to implement Serializable. For example, for the simple object:

public class MyClass implements Serializable {
    private static final long serialVersionUID = -2163051469151804394L;
    private int id;
    private String created;
}

In you FromFragment:

Bundle args = new Bundle();
args.putSerializable(TAG_MY_CLASS, myClass);
Fragment toFragment = new ToFragment();
toFragment.setArguments(args);
getFragmentManager()
    .beginTransaction()
    .replace(R.id.body, toFragment, TAG_TO_FRAGMENT)
    .addToBackStack(TAG_TO_FRAGMENT).commit();

in your ToFragment:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

    Bundle args = getArguments();
    MyClass myClass = (MyClass) args
        .getSerializable(TAG_MY_CLASS);

This is a long post, but I was tired of all these examples that weren't working for me because they used Promise objects or an errant this that has a different meaning when you are using Reactjs. My implementation was using a DropZone with reactjs, and I got the bytes using a framework similar to what is posted at this following site, when nothing else above would work: https://www.mokuji.me/article/drop-upload-tutorial-1 . There were 2 keys, for me:

1. You have to get the bytes from the event object, using and during a FileReader's onload function.

2. I tried various combinations, but in the end, what worked was:

   const bytes = e.target.result.split('base64,')[1];

Where e is the event. React requires const, you could use var in plain Javascript. But that gave me the base64 encoded byte string.

So I'm just going to include the applicable lines for integrating this as if you were using React, because that's how I was building it, but try to also generalize this, and add comments where necessary, to make it applicable to a vanilla Javascript implementation - caveated that I did not use it like that in such a construct to test it.

These would be your bindings at the top, in your constructor, in a React framework (not relevant to a vanilla Javascript implementation):

this.uploadFile = this.uploadFile.bind(this);
this.processFile = this.processFile.bind(this);
this.errorHandler = this.errorHandler.bind(this);
this.progressHandler = this.progressHandler.bind(this);

And you'd have onDrop={this.uploadFile} in your DropZone element. If you were doing this without React, this is the equivalent of adding the onclick event handler you want to run when you click the "Upload File" button.

<button onclick="uploadFile(event);" value="Upload File" />

Then the function (applicable lines... I'll leave out my resetting my upload progress indicator, etc.):

uploadFile(event){
    // This is for React, only
    this.setState({
      files: event,
    });
    console.log('File count: ' + this.state.files.length);

    // You might check that the "event" has a file & assign it like this 
    // in vanilla Javascript:
    // var files = event.target.files;
    // if (!files && files.length > 0)
    //     files = (event.dataTransfer ? event.dataTransfer.files : 
    //            event.originalEvent.dataTransfer.files);

    // You cannot use "files" as a variable in React, however:
    const in_files = this.state.files;

    // iterate, if files length > 0
    if (in_files.length > 0) {
      for (let i = 0; i < in_files.length; i++) {
      // use this, instead, for vanilla JS:
      // for (var i = 0; i < files.length; i++) {
        const a = i + 1;
        console.log('in loop, pass: ' + a);
        const f = in_files[i];  // or just files[i] in vanilla JS

        const reader = new FileReader();
        reader.onerror = this.errorHandler;
        reader.onprogress = this.progressHandler;
        reader.onload = this.processFile(f);
        reader.readAsDataURL(f);
      }      
   }
}

There was this question on that syntax, for vanilla JS, on how to get that file object:

JavaScript/HTML5/jQuery Drag-And-Drop Upload - "Uncaught TypeError: Cannot read property 'files' of undefined"

Note that React's DropZone will already put the File object into this.state.files for you, as long as you add files: [], to your this.state = { .... } in your constructor. I added syntax from an answer on that post on how to get your File object. It should work, or there are other posts there that can help. But all that Q/A told me was how to get the File object, not the blob data, itself. And even if I did fileData = new Blob([files[0]]); like in sebu's answer, which didn't include var with it for some reason, it didn't tell me how to read that blob's contents, and how to do it without a Promise object. So that's where the FileReader came in, though I actually tried and found I couldn't use their readAsArrayBuffer to any avail.

You will have to have the other functions that go along with this construct - one to handle onerror, one for onprogress (both shown farther below), and then the main one, onload, that actually does the work once a method on reader is invoked in that last line. Basically you are passing your event.dataTransfer.files[0] straight into that onload function, from what I can tell.

So the onload method calls my processFile() function (applicable lines, only):

processFile(theFile) {
  return function(e) {
    const bytes = e.target.result.split('base64,')[1];
  }
}

And bytes should have the base64 bytes.

Additional functions:

errorHandler(e){
    switch (e.target.error.code) {
      case e.target.error.NOT_FOUND_ERR:
        alert('File not found.');
        break;
      case e.target.error.NOT_READABLE_ERR:
        alert('File is not readable.');
        break;
      case e.target.error.ABORT_ERR:
        break;    // no operation
      default:
        alert('An error occurred reading this file.');
        break;
    }
  }

progressHandler(e) {
    if (e.lengthComputable){
      const loaded = Math.round((e.loaded / e.total) * 100);
      let zeros = '';

      // Percent loaded in string
      if (loaded >= 0 && loaded < 10) {
        zeros = '00';
      }
      else if (loaded < 100) {
        zeros = '0';
      }

      // Display progress in 3-digits and increase bar length
      document.getElementById("progress").textContent = zeros + loaded.toString();
      document.getElementById("progressBar").style.width = loaded + '%';
    }
  }

And applicable progress indicator markup:

<table id="tblProgress">
  <tbody>
    <tr>
      <td><b><span id="progress">000</span>%</b> <span className="progressBar"><span id="progressBar" /></span></td>
    </tr>                    
  </tbody>
</table>

And CSS:

.progressBar {
  background-color: rgba(255, 255, 255, .1);
  width: 100%;
  height: 26px;
}
#progressBar {
  background-color: rgba(87, 184, 208, .5);
  content: '';
  width: 0;
  height: 26px;
}

EPILOGUE:

Inside processFile(), for some reason, I couldn't add bytes to a variable I carved out in this.state. So, instead, I set it directly to the variable, attachments, that was in my JSON object, RequestForm - the same object as my this.state was using. attachments is an array so I could push multiple files. It went like this:

  const fileArray = [];
  // Collect any existing attachments
  if (RequestForm.state.attachments.length > 0) {
    for (let i=0; i < RequestForm.state.attachments.length; i++) {
      fileArray.push(RequestForm.state.attachments[i]);
    }
  }
  // Add the new one to this.state
  fileArray.push(bytes);
  // Update the state
  RequestForm.setState({
    attachments: fileArray,
  });

Then, because this.state already contained RequestForm:

this.stores = [
  RequestForm,    
]

I could reference it as this.state.attachments from there on out. React feature that isn't applicable in vanilla JS. You could build a similar construct in plain JavaScript with a global variable, and push, accordingly, however, much easier:

var fileArray = new Array();  // place at the top, before any functions

// Within your processFile():
var newFileArray = [];
if (fileArray.length > 0) {
  for (var i=0; i < fileArray.length; i++) {
    newFileArray.push(fileArray[i]);
  }
}
// Add the new one
newFileArray.push(bytes);
// Now update the global variable
fileArray = newFileArray;

Then you always just reference fileArray, enumerate it for any file byte strings, e.g. var myBytes = fileArray[0]; for the first file.

This is not possible, it will give you a compile time error,

You can use array for this type of requirement .

The Python 3 range() object doesn't produce numbers immediately; it is a smart sequence object that produces numbers on demand. All it contains is your start, stop and step values, then as you iterate over the object the next integer is calculated each iteration.

The object also implements the object.__contains__ hook, and calculates if your number is part of its range. Calculating is a (near) constant time operation ^*. There is never a need to scan through all possible integers in the range.

From the range() object documentation:

The advantage of the range type over a regular list or tuple is that a range object will always take the same (small) amount of memory, no matter the size of the range it represents (as it only stores the start, stop and step values, calculating individual items and subranges as needed).

So at a minimum, your range() object would do:

class my_range:
    def __init__(self, start, stop=None, step=1, /):
        if stop is None:
            start, stop = 0, start
        self.start, self.stop, self.step = start, stop, step
        if step < 0:
            lo, hi, step = stop, start, -step
        else:
            lo, hi = start, stop
        self.length = 0 if lo > hi else ((hi - lo - 1) // step) + 1

    def __iter__(self):
        current = self.start
        if self.step < 0:
            while current > self.stop:
                yield current
                current += self.step
        else:
            while current < self.stop:
                yield current
                current += self.step

    def __len__(self):
        return self.length

    def __getitem__(self, i):
        if i < 0:
            i += self.length
        if 0 <= i < self.length:
            return self.start + i * self.step
        raise IndexError('my_range object index out of range')

    def __contains__(self, num):
        if self.step < 0:
            if not (self.stop < num <= self.start):
                return False
        else:
            if not (self.start <= num < self.stop):
                return False
        return (num - self.start) % self.step == 0

This is still missing several things that a real range() supports (such as the .index() or .count() methods, hashing, equality testing, or slicing), but should give you an idea.

I also simplified the __contains__ implementation to only focus on integer tests; if you give a real range() object a non-integer value (including subclasses of int), a slow scan is initiated to see if there is a match, just as if you use a containment test against a list of all the contained values. This was done to continue to support other numeric types that just happen to support equality testing with integers but are not expected to support integer arithmetic as well. See the original Python issue that implemented the containment test.

* Near constant time because Python integers are unbounded and so math operations also grow in time as N grows, making this a O(log N) operation. Since it’s all executed in optimised C code and Python stores integer values in 30-bit chunks, you’d run out of memory before you saw any performance impact due to the size of the integers involved here.

PHP provides two types of array.

• normal array
• SplFixedArray

normal array : This array is dynamic.

SplFixedArray : this is a standard php library which provides the ability to create array of fix size.

Not related to question but in case if someone is passing the string as an argument to bash script this might help.

Use:

./bash_script.sh "path\to\file"

Instead of:

./bash_script.sh path\to\file

Completing the solution of Ranadheer, using Server.MapPath to locate the file

System.Net.Mail.Attachment attachment;
attachment = New System.Net.Mail.Attachment(Server.MapPath("~/App_Data/hello.pdf"));
mail.Attachments.Add(attachment);

I don't see any answers yet that mention performance. Passing Func<>s into Where() or Count() is bad. Real bad. If you use a Func<> then it calls the IEnumerable LINQ stuff instead of IQueryable, which means that whole tables get pulled in and then filtered. Expression<Func<>> is significantly faster, especially if you are querying a database that lives another server.

If you want to stick with the way you're populating the values array, you can then assign this array like so:

BODY.values = values;

after the loop.

It should look like this:

var BODY = {
    "recipients": {
      "values": [
     ]
    },
   "subject": title,
   "body": message
}

var values = [];
for (var ln = 0; ln < names.length; ln++) {
var item1 = {
    "person": {
            "_path": "/people/"+names[ln],
            },
};
values.push(item1);
}
BODY.values = values;
alert(BODY);

JSON.stringify() will be useful once you pass it as parameter for an AJAX call. Remember: the values array in your BODY object is different from the var values = []. You must assign that outer values[] to BODY.values. This is one of the good things about OOP.

"Baker"

That's because the first one changes your string-reference to point to "Baker". Changing the reference is possible because you passed it via the ref keyword (=> a reference to a reference to a string). The Second call gets a copy of the reference to the string.

string looks some kind of special at first. But string is just a reference class and if you define

string s = "Able";

then s is a reference to a string class that contains the text "Able"! Another assignment to the same variable via

s = "Baker";

does not change the original string but just creates a new instance and let s point to that instance!

You can try it with the following little code example:

string s = "Able";
string s2 = s;
s = "Baker";
Console.WriteLine(s2);

What do you expect? What you will get is still "Able" because you just set the reference in s to another instance while s2 points to the original instance.

EDIT: string is also immutable which means there is simply no method or property that modifies an existing string instance (you can try to find one in the docs but you won't fins any :-) ). All string manipulation methods return a new string instance! (That's why you often get a better performance when using the StringBuilder class)

Try this

String[] array = values.split("\\|",-1); 

Directed graph:

Question: What's the maximum number of edges in a directed graph with n vertices?

• Assume there are no self-loops.
• Assume there there is at most one edge from a given start vertex to a given end vertex.

Each edge is specified by its start vertex and end vertex. There are n choices for the start vertex. Since there are no self-loops, there are n-1 choices for the end vertex. Multiplying these together counts all possible choices.

Answer: n(n-1)

Undirected graph

Question: What's the maximum number of edges in an undirected graph with n vertices?

• Assume there are no self-loops.
• Assume there there is at most one edge from a given start vertex to a given end vertex.

In an undirected graph, each edge is specified by its two endpoints and order doesn't matter. The number of edges is therefore the number of subsets of size 2 chosen from the set of vertices. Since the set of vertices has size n, the number of such subsets is given by the binomial coefficient C(n,2) (also known as "n choose 2"). Using the formula for binomial coefficients, C(n,2) = n(n-1)/2.

Answer: (n*(n-1))/2

I've captured the communication of Outlook plugin for Facebook and here is the POST request

https://api.facebook.com/method/fql.multiquery
access_token=TOKEN&queries={"USER0":"select '0', uid, name, birthday_date, profile_url, pic, website from user where uid in (select uid from email where email in ('EMAIL_HASH'))","PENDING_OUT":"select uid_to from friend_request where uid_from = MY_ID and (uid_to IN (select uid from #USER0))"}

where
TOKEN - valid access token
EMAIL_HASH - combination of CRC32 and MD5 hash of searched email address in format crc32_md5
MY_ID - ID of facebook profile of access token owner

But when I run this query with different access token (generated for my own application) the server response is: "The table you requested does not exist" I also haven't found the table email in Facebook API documentation. Does Microsoft have some extra rights at Facebook?

Check out pyftpdlib from Giampaolo Rodola. It is one of the very best ftp servers out there for python. It's used in google's chromium (their browser) and bazaar (a version control system). It is the most complete implementation on Python for RFC-959 (aka: FTP server implementation spec).

To install:

pip3 install pyftpdlib

From the commandline:

python3 -m pyftpdlib

Alternatively 'my_server.py':

#!/usr/bin/env python3

from pyftpdlib import servers
from pyftpdlib.handlers import FTPHandler
address = ("0.0.0.0", 21)  # listen on every IP on my machine on port 21
server = servers.FTPServer(address, FTPHandler)
server.serve_forever()

There's more examples on the website if you want something more complicated.

To get a list of command line options:

python3 -m pyftpdlib --help

Note, if you want to override or use a standard ftp port, you'll need admin privileges (e.g. sudo).

Those other variables would have to be declared public (use extern, public is for C++), and you would have to include that .c file. However, I recommend creating appropriate .h files to define all of your variables.

For example, for hello.c, you would have a hello.h, and hello.h would store your variable definitions. Then another .c file, such as world.c would have this piece of code at the top:

#include "hello.h"

That will allow world.c to use variables that are defined in hello.h

It's slightly more complicated than that though. You may use < > to include library files found on your OS's path. As a beginner I would stick all of your files in the same folder and use the " " syntax.

you can try this indside findall for loop:

item_price = item.find('span', attrs={'class':'s-item__price'}).text

it extracts only text and assigs it to "item_pice"

The simplest solution would be to use Pillow lib:

from PIL import Image

image = Image.fromarray(<your_numpy_array>.astype(np.uint8))

And you can use it as an image.

This worked for me may times:

ssh -x remoteServer "cd yourRemoteDir; ./yourRemoteScript.sh </dev/null >/dev/null 2>&1 & " 

Seems you forgot the '' of your string.

In [43]: df['Value'] = df.apply(lambda row: my_test(row['a'], row['c']), axis=1)

In [44]: df
Out[44]:
                    a    b         c     Value
          0 -1.674308  foo  0.343801  0.044698
          1 -2.163236  bar -2.046438 -0.116798
          2 -0.199115  foo -0.458050 -0.199115
          3  0.918646  bar -0.007185 -0.001006
          4  1.336830  foo  0.534292  0.268245
          5  0.976844  bar -0.773630 -0.570417

BTW, in my opinion, following way is more elegant:

In [53]: def my_test2(row):
....:     return row['a'] % row['c']
....:     

In [54]: df['Value'] = df.apply(my_test2, axis=1)

It is not a good idea to return iterators. Iterators become invalid when modifications to the vector (inversion\deletion ) happens. Also, the iterator is a local object created on stack and hence returning the address of the same is not at all safe. I'd suggest you to work with myObject rather than vector iterators.

EDIT: If the object is lightweight then its better you return the object itself. Otheriwise return pointers to myObject stored in the vector.

HTML5 spec:

http://www.w3.org/TR/html5/forms.html#enabling-and-disabling-form-controls:-the-disabled-attribute :

The checked content attribute is a boolean attribute

http://www.w3.org/TR/html5/infrastructure.html#boolean-attributes :

The presence of a boolean attribute on an element represents the true value, and the absence of the attribute represents the false value.

If the attribute is present, its value must either be the empty string or a value that is an ASCII case-insensitive match for the attribute's canonical name, with no leading or trailing whitespace.

Conclusion:

The following are valid, equivalent and true:

<input type="text" disabled />
<input type="text" disabled="" />
<input type="text" disabled="disabled" />
<input type="text" disabled="DiSaBlEd" />

The following are invalid:

<input type="text" disabled="0" />
<input type="text" disabled="1" />
<input type="text" disabled="false" />
<input type="text" disabled="true" />

The absence of the attribute is the only valid syntax for false:

<input type="text" />

Recommendation

If you care about writing valid XHTML, use disabled="disabled", since <input disabled> is invalid and other alternatives are less readable. Else, just use <input disabled> as it is shorter.

I don't think the solution presented here is 100% correct because window.onbeforeunload event is called not only when browser/Tab is closed(WHICH IS REQUIRED), but also on all other several events. (WHICH MIGHT NOT BE REQUIRED)

Guava provides this: Lists.reverse(List)

List<String> letters = ImmutableList.of("a", "b", "c");
List<String> reverseView = Lists.reverse(letters); 
System.out.println(reverseView); // [c, b, a]

Unlike Collections.reverse, this is purely a view... it doesn't alter the ordering of elements in the original list. Additionally, with an original list that is modifiable, changes to both the original list and the view are reflected in the other.

Python lists have the index() method, which you can use to find the position of the first occurrence of an item in a list. Note that list.index() raises ValueError when the item is not present in the list, so you may need to wrap it in try/except:

try:
    idx = lst.index(value)
except ValueError:
    idx = None

To find the position of the last occurrence of an item in a list efficiently (i.e. without creating a reversed intermediate list) you can use this function:

def rindex(lst, value):
    for i, v in enumerate(reversed(lst)):
        if v == value:
            return len(lst) - i - 1  # return the index in the original list
    return None    

print(rindex([1, 2, 3], 3))     # 2
print(rindex([3, 2, 1, 3], 3))  # 3
print(rindex([3, 2, 1, 3], 4))  # None

jQuery CROSS BROWSER CUSTOM PLUGIN - $.footerBottom()

Or use jQuery like I do, and set your footer height to auto or to fix, whatever you like, it will work anyway. this plugin uses jQuery selectors so to make it work, you will have to include the jQuery library to your file.

Here is how you run the plugin. Import jQuery, copy the code of this custom jQuery plugin and import it after importing jQuery! It is very simple and basic, but important.

When you do it, all you have to do is run this code:

$.footerBottom({target:"footer"}); //as html5 tag <footer>.
// You can change it to your preferred "div" with for example class "footer" 
// by setting target to {target:"div.footer"}

there is no need to place it inside the document ready event. It will run well as it is. It will recalculate the position of your footer when the page is loaded and when the window get resized.

Here is the code of the plugin which you do not have to understand. Just know how to implement it. It does the job for you. However, if you like to know how it works, just look through the code. I left comments for you.

You should also not use CAST for getting the text of a hash algorithm. CAST(HASHBYTES('...') AS VARCHAR(32)) is not the same as CONVERT(VARCHAR(32), HASHBYTES('...'), 2). Without the last parameter, the result would be the same, but not a readable text. As far as I know, You cannot specify that last parameter in CAST.

In case you need to apply a dynamic delay with the lodash's debounce function:

props: {
  delay: String
},

data: () => ({
  search: null
}),

created () {
     this.valueChanged = debounce(function (event) {
      // Here you have access to `this`
      this.makeAPIrequest(event.target.value)
    }.bind(this), this.delay)

},

methods: {
  makeAPIrequest (newVal) {
    // ...
  }
}

And the template:

<template>
  //...

   <input type="text" v-model="search" @input="valueChanged" />

  //...
</template>

NOTE: in the example above I made an example of search input which can call the API with a custom delay which is provided in props

I just experienced a further permutation of this issue.

I had a branch named feat/XYZ-1234-some-description because I was working on Jira issue 1234. During the work I created a new Jira issue to track a smaller piece of work, and when I came to push I decided to push to a branch name with this new issue number in:

git push -u origin feat/XYZ-5678-a-different-description # failed

This gave me the error being discussed in this SO thread. But since I was trying to push to a different branch name from my current branch, my problem was different to the one described here. I ended up renaming my local branch before I could push it:

git branch -m feat/XYZ-1234-some-description feat/XYZ-5678-a-different-description
git push -u origin feat/XYZ-5678-a-different-description # now works

After a bit more reading around I realised that I could have set a src on the git push, either to the current branch name, or just HEAD if appropriate:

git push -u origin feat/XYZ-1234-some-description:feat/XYZ-5678-a-different-description # also works

What I did was to create a canvas element that I then position in front of the image map. Then, whenever an area is moused-over, I call a func that gets the coord string for that shape and the shape-type. If it's a poly I use the coords to draw an outline on the canvas. If it's a rect I draw a rect outline. You could easily add code to deal with circles.

You could also set the opacity of the canvas to less than 100% before filling the poly/rect/circle. You could also change the reliance on a global for the canvas's context - this would mean you could deal with more than 1 image-map on the same page.

// draws a line from each co-ord pair to the next - assumes starting point needs to be repeated as ending point.

Solution that preserves unhandled arguments. Demos Included.

Here is my solution. It is VERY flexible and unlike others, shouldn't require external packages and handles leftover arguments cleanly.

Usage is: ./myscript -flag flagvariable -otherflag flagvar2

All you have to do is edit the validflags line. It prepends a hyphen and searches all arguments. It then defines the next argument as the flag name e.g.

./myscript -flag flagvariable -otherflag flagvar2
echo $flag $otherflag
flagvariable flagvar2

The main code (short version, verbose with examples further down, also a version with erroring out):

#!/usr/bin/env bash
#shebang.io
validflags="rate time number"
count=1
for arg in $@
do
    match=0
    argval=$1
    for flag in $validflags
    do
        sflag="-"$flag
        if [ "$argval" == "$sflag" ]
        then
            declare $flag=$2
            match=1
        fi
    done
        if [ "$match" == "1" ]
    then
        shift 2
    else
        leftovers=$(echo $leftovers $argval)
        shift
    fi
    count=$(($count+1))
done
#Cleanup then restore the leftovers
shift $#
set -- $leftovers

The verbose version with built in echo demos:

#!/usr/bin/env bash
#shebang.io
rate=30
time=30
number=30
echo "all args
$@"
validflags="rate time number"
count=1
for arg in $@
do
    match=0
    argval=$1
#   argval=$(echo $@ | cut -d ' ' -f$count)
    for flag in $validflags
    do
            sflag="-"$flag
        if [ "$argval" == "$sflag" ]
        then
            declare $flag=$2
            match=1
        fi
    done
        if [ "$match" == "1" ]
    then
        shift 2
    else
        leftovers=$(echo $leftovers $argval)
        shift
    fi
    count=$(($count+1))
done

#Cleanup then restore the leftovers
echo "pre final clear args:
$@"
shift $#
echo "post final clear args:
$@"
set -- $leftovers
echo "all post set args:
$@"
echo arg1: $1 arg2: $2

echo leftovers: $leftovers
echo rate $rate time $time number $number

Final one, this one errors out if an invalid -argument is passed through.

#!/usr/bin/env bash
#shebang.io
rate=30
time=30
number=30
validflags="rate time number"
count=1
for arg in $@
do
    argval=$1
    match=0
        if [ "${argval:0:1}" == "-" ]
    then
        for flag in $validflags
        do
                sflag="-"$flag
            if [ "$argval" == "$sflag" ]
            then
                declare $flag=$2
                match=1
            fi
        done
        if [ "$match" == "0" ]
        then
            echo "Bad argument: $argval"
            exit 1
        fi
        shift 2
    else
        leftovers=$(echo $leftovers $argval)
        shift
    fi
    count=$(($count+1))
done
#Cleanup then restore the leftovers
shift $#
set -- $leftovers
echo rate $rate time $time number $number
echo leftovers: $leftovers

Pros: What it does, it handles very well. It preserves unused arguments which a lot of the other solutions here don't. It also allows for variables to be called without being defined by hand in the script. It also allows prepopulation of variables if no corresponding argument is given. (See verbose example).

Cons: Can't parse a single complex arg string e.g. -xcvf would process as a single argument. You could somewhat easily write additional code into mine that adds this functionality though.

I was getting similar problem for other reason (url pattern test-response not added in csrf token) I resolved it by allowing my URL pattern in following property in config/local.properties:

csrf.allowed.url.patterns = /[^/]+(/[^?])+(sop-response)$,/[^/]+(/[^?])+(merchant_callback)$,/[^/]+(/[^?])+(hop-response)$

modified to

csrf.allowed.url.patterns = /[^/]+(/[^?])+(sop-response)$,/[^/]+(/[^?])+(merchant_callback)$,/[^/]+(/[^?])+(hop-response)$,/[^/]+(/[^?])+(test-response)$

Once id of iframe is set, you can access iframe from inner document as shown below.

var iframe = parent.document.getElementById(frameElement.id);

Works well in IE, Chrome and FF.

I'd say:

 <a href="#"id="buttonOne">
            <div id="linkedinB">
                <img src="img/linkedinB.png" width="40" height="40">
            </div>
      </div> 

However, it will still be a link. If you want to change your link into a button, you should rename the #buttonone to #buttonone a { your css here }.

View-Page

<h:selectOneMenu id="selectOneCB" value="#{page.selectedName}">
     <f:selectItems value="#{page.names}"/>
</h:selectOneMenu>

Backing-Bean

   List<SelectItem> names = new ArrayList<SelectItem>();

   //-- Populate list from database

   names.add(new SelectItem(valueObject,"label"));

   //-- setter/getter accessor methods for list

To display particular selected record, it must be one of the values in the list.

what i find is that:

in bootstrap 3.3.0 it's not right,but when in bootstrap 3.3.5 it's right.let's see the code. 3.3.0:

this.$backdrop = $('<div class="modal-backdrop ' + animate + '" />')
    .prependTo(this.$element)

3.3.5

  this.$backdrop = $(document.createElement('div'))
        .addClass('modal-backdrop ' + animate)
        .appendTo(this.$body)

I solve this problem by always using the [h] option on floats (such as figures) so that they (mostly) go where I place them. Then when I look at the final draft, I adjust the location of the float by moving it in the LaTeX source. Usually that means moving it around the paragraph where it is referenced. Sometimes I need to add a page break at an appropriate spot.

I've found that the default placement of floats is reasonable in LaTeX, but manual adjustments are almost always needed to get things like this just right. (And sometimes it isn't possible for everything to be perfect when there are lots of floats and footnotes.)

The manual for the memoir class has some good information about how LaTeX places floats and some advice for manipulating the algorithm.

For chat applications or any other application that is in constant conversation with the server, WebSockets are the best option. However, you can only use WebSockets with a server that supports them, so that may limit your ability to use them if you cannot install the required libraries. In which case, you would need to use Long Polling to obtain similar functionality.

If you would like to modify file names in an editor (such as vim), the click library comes with the command click.edit(), which can be used to receive user input from an editor. Here is an example of how it can be used to refactor files in a directory.

import click
from pathlib import Path

# current directory
direc_to_refactor = Path(".")

# list of old file paths
old_paths = list(direc_to_refactor.iterdir())

# list of old file names
old_names = [str(p.name) for p in old_paths]

# modify old file names in an editor,
# and store them in a list of new file names
new_names = click.edit("\n".join(old_names)).split("\n")

# refactor the old file names
for i in range(len(old_paths)):
    old_paths[i].replace(direc_to_refactor / new_names[i])

I wrote a command line application that uses the same technique, but that reduces the volatility of this script, and comes with more options, such as recursive refactoring. Here is the link to the github page. This is useful if you like command line applications, and are interested in making some quick edits to file names. (My application is similar to the "bulkrename" command found in ranger).

Another approach is using Object.defineProperty to set valueas a getter setter property in the controller scope, then each change on the value property will trigger a function specified in the setter:

The HTML file:

<input type="radio" ng-model="value" value="one"/>
<input type="radio" ng-model="value" value="two"/>
<input type="radio" ng-model="value" value="three"/>

The javascript file:

var _value = null;
Object.defineProperty($scope, 'value', {
  get: function () {
    return _value;
  },         
  set: function (value) {
    _value = value;
    someFunction();
  }
});

see this plunker for the implementation

Needed a break, so I cobbled the following together. Not sure it would be worth creating a plugin from though.

$("a.save, #country") 

will select both "a.save" class and "country" id.

I just described very popular library clint. Which has more features apart of coloring the output on terminal.

By the way it support MAC, Linux and Windows terminals.

Here is the example of using it:

Installing (in Ubuntu)

pip install clint

To add color to some string

colored.red('red string')

Example: Using for color output (django command style)

from django.core.management.base import BaseCommand
from clint.textui import colored


class Command(BaseCommand):
    args = ''
    help = 'Starting my own django long process. Use ' + colored.red('<Ctrl>+c') + ' to break.'

    def handle(self, *args, **options):
        self.stdout.write('Starting the process (Use ' + colored.red('<Ctrl>+c') + ' to break)..')
        # ... Rest of my command code ...

Also answering this question:

Where can I get pre-built JavaFX libraries for OpenJDK (Windows)

On Linux its not really a problem, but on Windows its not that easy, especially if you want to distribute the JRE.

You can actually use OpenJFX with OpenJDK 8 on windows, you just have to assemble it yourself:

Download the OpenJDK from here: https://github.com/AdoptOpenJDK/openjdk8-releases/releases/tag/jdk8u172-b11

Download OpenJFX from here: https://github.com/SkyLandTW/OpenJFX-binary-windows/releases/tag/v8u172-b11

copy all the files from the OpenFX zip on top of the JDK, voila, you have an OpenJDK with JavaFX.

Update:

Fortunately from Azul there is now a OpenJDK+OpenJFX build which can be downloaded at their community page: https://www.azul.com/downloads/zulu-community/?&version=java-8-lts&os=windows&package=jdk-fx

There's also one another silly reason which you should check with patience... as it occurred to me after wasting 4hours searching for answers:

The story to me was that I accidentally changed a small line of code among thousands of c# class files and then trying to rebuild the solution. As you could imagine, I ended up with 40+ meta data file missing errors and with 1 compilation error among them -- which I didn't check carefully, purely thinking all errors were the same!

after 4 hours searching and then accidentally double checking my error list, I found that silly code error, fixed it, compiled, and then error disappeared.

Not a good answer to your problem, but do hope my case wasn't same to yours.

folks, I got this Bootstrap dropdown working. I modified the click event slightly in order to keep the currently-selected image. And as you see, the USD currency is the default selected :

<div class="btn-group" style="margin:10px;">    <!-- CURRENCY, BOOTSTRAP DROPDOWN -->
                <!--<a class="btn btn-primary" href="javascript:void(0);">Currency</a>-->                    
                <a class="btn btn-primary dropdown-toggle" data-toggle="dropdown" href="#"><img src="../../Images/flag-usd-small.png"> USD <span class="caret"></span></a>
                <ul class="dropdown-menu">
                    <li><a href="javascript:void(0);">
                        <img src="../../Images/flag-aud-small.png" /> AUD</a>
                    </li>
                    <li><a href="javascript:void(0);">
                        <img src="../../Images/flag-cad-small.png" /> CAD</a>
                    </li>
                    <li><a href="javascript:void(0);">
                        <img src="../../Images/flag-cny-small.png" /> CNY</a>
                    </li>
                    <li><a href="javascript:void(0);">
                        <img src="../../Images/flag-gbp-small.png" /> GBP</a>
                    </li>
                    <li><a href="javascript:void(0);">
                        <img src="../../Images/flag-usd-small.png" /> USD</a>
                    </li>
                </ul>
            </div>


/* BOOTSTRAP DROPDOWN MENU - Update selected item text and image */
$(".dropdown-menu li a").click(function () {
    var selText = $(this).text();
    var imgSource = $(this).find('img').attr('src');
    var img = '<img src="' + imgSource + '"/>';        
    $(this).parents('.btn-group').find('.dropdown-toggle').html(img + ' ' + selText + ' <span class="caret"></span>');
});

You could convert your values into a 'Decimal' datetime and convert it then to a real datetime column:

select cast(rtrim(year *10000+ month *100+ day) as datetime) as Date from DateTable

See here as well for more info.

The basic syntax for using ternary operator is like this:

(condition) ? (if_true) : (if_false)

For you case it is like this:

number < 0 ? bigInt.sign = 0 : bigInt.sign = 1;

One way to sync your database to your django models is to delete your database file and run makemigrations and migrate commands again. This will reflect your django models structure to your database from scratch. Although, make sure to backup your database file before deleting in case you need your records.

This solution worked for me since I wasn't much bothered about the data and just wanted my db and models structure to sync up.

Use UIAppearance protocol. Do more hacks with appearanceFont to change font for UIAlertAction.

Create a category for UILabel

UILabel+FontAppearance.h

@interface UILabel (FontAppearance)

@property (nonatomic, copy) UIFont * appearanceFont UI_APPEARANCE_SELECTOR;

@end

UILabel+FontAppearance.m

@implementation UILabel (FontAppearance)

- (void)setAppearanceFont:(UIFont *)font
{
    if (self.tag == 1001) {
        return;
    }

    BOOL isBold = (self.font.fontDescriptor.symbolicTraits & UIFontDescriptorTraitBold);
    const CGFloat* colors = CGColorGetComponents(self.textColor.CGColor);

    if (self.font.pointSize == 14) {
        // set font for UIAlertController title
        self.font = [UIFont systemFontOfSize:11];
    } else if (self.font.pointSize == 13) {
        // set font for UIAlertController message
        self.font = [UIFont systemFontOfSize:11];
    } else if (isBold) {
        // set font for UIAlertAction with UIAlertActionStyleCancel
        self.font = [UIFont systemFontOfSize:12];
    } else if ((*colors) == 1) {
        // set font for UIAlertAction with UIAlertActionStyleDestructive
        self.font = [UIFont systemFontOfSize:13];
    } else {
        // set font for UIAlertAction with UIAlertActionStyleDefault
        self.font = [UIFont systemFontOfSize:14];
    }
    self.tag = 1001;
}

- (UIFont *)appearanceFont
{
    return self.font;
}

@end

Usage:

add

[[UILabel appearanceWhenContainedIn:UIAlertController.class, nil] setAppearanceFont:nil];

in AppDelegate.m to make it work for all UIAlertController.

You can also use SugarJS in NodeJS.

http://sugarjs.com/

They have a very clean clone feature: http://sugarjs.com/api/Object/clone

What I've found useful is to know which copy/paste buffer (register) is currently active: %{v:register}. Otherwise, my complete status line looks almost exactly like the standard line.

:set statusline=%<%f\ %h%m%r\ %y%=%{v:register}\ %-14.(%l,%c%V%)\ %P

The OP had the best answer for me and it appears that others have figured out the -All addition as well. I set up two batch files, then shortcuts to those so you can set the Run As Admin permissions on them, easy-peasy.

Batch Off

Call dism.exe /Online /Disable-Feature:Microsoft-Hyper-V-All

Batch On

Call dism.exe /Online /Enable-Feature:Microsoft-Hyper-V /All

Right-click -> create desktop shortcut. Right-click the shortcut -> properties -> under the shortcut tab -> Advanced -> Run as admin

Add /B, as documented in the command-line help for start:

C:\>start /?
Starts a separate window to run a specified program or command.

START ["title"] [/D path] [/I] [/MIN] [/MAX] [/SEPARATE | /SHARED]
  [/LOW | /NORMAL | /HIGH | /REALTIME | /ABOVENORMAL | /BELOWNORMAL]
  [/NODE <NUMA node>] [/AFFINITY <hex affinity mask>] [/WAIT] [/B]
  [command/program] [parameters]

"title"     Title to display in window title bar.
path        Starting directory.
B           Start application without creating a new window. The
            application has ^C handling ignored. Unless the application
            enables ^C processing, ^Break is the only way to interrupt
            the application.

It can be used to use features which will appear in newer versions while having an older release of Python.

For example

>>> from __future__ import print_function

will allow you to use print as a function:

>>> print('# of entries', len(dictionary), file=sys.stderr)

You might take advantage of ruby's "splat" or flattening syntax.

This makes overgrown when clauses — you have about 10 values to test per branch if I understand correctly — a little more readable in my opinion. Additionally, you can modify the values to test at runtime. For example:

honda  = ['honda', 'acura', 'civic', 'element', 'fit', ...]
toyota = ['toyota', 'lexus', 'tercel', 'rx', 'yaris', ...]
...

if include_concept_cars
  honda += ['ev-ster', 'concept c', 'concept s', ...]
  ...
end

case car
when *toyota
  # Do something for Toyota cars
when *honda
  # Do something for Honda cars
...
end

Another common approach would be to use a hash as a dispatch table, with keys for each value of car and values that are some callable object encapsulating the code you wish to execute.

To view the files just browse them from the command prompt (cmd), eg.:

c:\>cd \Windows\assembly\GAC_32
c:\Windows\assembly\GAC_32> dir

To add and remove files from the GAC use the tool gacutil

for china GFW:

sudo iptables -I INPUT -s 173.194.0.0/16 -p tcp --tcp-flags RST RST -j DROP
sudo iptables -I INPUT -s 173.194.0.0/16 -p tcp --tcp-flags RST RST -j LOG --log-prefix "drop rst"

sudo iptables -I INPUT -s 64.233.0.0/16 -p tcp --tcp-flags RST RST -j DROP
sudo iptables -I INPUT -s 64.233.0.0/16 -p tcp --tcp-flags RST RST -j LOG --log-prefix "drop rst"

sudo iptables -I INPUT -s 74.125.0.0/16 -p tcp --tcp-flags RST RST -j DROP
sudo iptables -I INPUT -s 74.125.0.0/16 -p tcp --tcp-flags RST RST -j LOG --log-prefix "drop rst"

select @DateCreated, DATEDIFF(WEEK, @DateCreated, GETDATE())

Below batch "program" should do what you want. Please note that it outputs the data in centiseconds instead of milliseconds. The precision of the used commands is only centiseconds.

Here is an example output:

STARTTIME: 13:42:52,25
ENDTIME: 13:42:56,51
STARTTIME: 4937225 centiseconds
ENDTIME: 4937651 centiseconds
DURATION: 426 in centiseconds
00:00:04,26

Here is the batch script:

@echo off
setlocal

rem The format of %TIME% is HH:MM:SS,CS for example 23:59:59,99
set STARTTIME=%TIME%

rem here begins the command you want to measure
dir /s > nul
rem here ends the command you want to measure

set ENDTIME=%TIME%

rem output as time
echo STARTTIME: %STARTTIME%
echo ENDTIME: %ENDTIME%

rem convert STARTTIME and ENDTIME to centiseconds
set /A STARTTIME=(1%STARTTIME:~0,2%-100)*360000 + (1%STARTTIME:~3,2%-100)*6000 + (1%STARTTIME:~6,2%-100)*100 + (1%STARTTIME:~9,2%-100)
set /A ENDTIME=(1%ENDTIME:~0,2%-100)*360000 + (1%ENDTIME:~3,2%-100)*6000 + (1%ENDTIME:~6,2%-100)*100 + (1%ENDTIME:~9,2%-100)

rem calculating the duratyion is easy
set /A DURATION=%ENDTIME%-%STARTTIME%

rem we might have measured the time inbetween days
if %ENDTIME% LSS %STARTTIME% set set /A DURATION=%STARTTIME%-%ENDTIME%

rem now break the centiseconds down to hors, minutes, seconds and the remaining centiseconds
set /A DURATIONH=%DURATION% / 360000
set /A DURATIONM=(%DURATION% - %DURATIONH%*360000) / 6000
set /A DURATIONS=(%DURATION% - %DURATIONH%*360000 - %DURATIONM%*6000) / 100
set /A DURATIONHS=(%DURATION% - %DURATIONH%*360000 - %DURATIONM%*6000 - %DURATIONS%*100)

rem some formatting
if %DURATIONH% LSS 10 set DURATIONH=0%DURATIONH%
if %DURATIONM% LSS 10 set DURATIONM=0%DURATIONM%
if %DURATIONS% LSS 10 set DURATIONS=0%DURATIONS%
if %DURATIONHS% LSS 10 set DURATIONHS=0%DURATIONHS%

rem outputing
echo STARTTIME: %STARTTIME% centiseconds
echo ENDTIME: %ENDTIME% centiseconds
echo DURATION: %DURATION% in centiseconds
echo %DURATIONH%:%DURATIONM%:%DURATIONS%,%DURATIONHS%

endlocal
goto :EOF

Just try this. It always works.

I'm very thoroughly investigating the matter of accuracy/rssi/proximity with iBeacons and I really really think that all the resources in the Internet (blogs, posts in StackOverflow) get it wrong.

davidgyoung (accepted answer, > 100 upvotes) says:

Note that the term "accuracy" here is iOS speak for distance in meters.

Actually, most people say this but I have no idea why! Documentation makes it very very clear that CLBeacon.proximity:

Indicates the one sigma horizontal accuracy in meters. Use this property to differentiate between beacons with the same proximity value. Do not use it to identify a precise location for the beacon. Accuracy values may fluctuate due to RF interference.

Let me repeat: one sigma accuracy in meters. All 10 top pages in google on the subject has term "one sigma" only in quotation from docs, but none of them analyses the term, which is core to understand this.

Very important is to explain what is actually one sigma accuracy. Following URLs to start with: http://en.wikipedia.org/wiki/Standard_error, http://en.wikipedia.org/wiki/Uncertainty

In physical world, when you make some measurement, you always get different results (because of noise, distortion, etc) and very often results form Gaussian distribution. There are two main parameters describing Gaussian curve:

1. mean (which is easy to understand, it's value for which peak of the curve occurs).
2. standard deviation, which says how wide or narrow the curve is. The narrower curve, the better accuracy, because all results are close to each other. If curve is wide and not steep, then it means that measurements of the same phenomenon differ very much from each other, so measurement has a bad quality.

one sigma is another way to describe how narrow/wide is gaussian curve.
It simply says that if mean of measurement is X, and one sigma is s, then 68% of all measurements will be between X - s and X + s.

Example. We measure distance and get a gaussian distribution as a result. The mean is 10m. If s is 4m, then it means that 68% of measurements were between 6m and 14m.

When we measure distance with beacons, we get RSSI and 1-meter calibration value, which allow us to measure distance in meters. But every measurement gives different values, which form gaussian curve. And one sigma (and accuracy) is accuracy of the measurement, not distance!

It may be misleading, because when we move beacon further away, one sigma actually increases because signal is worse. But with different beacon power-levels we can get totally different accuracy values without actually changing distance. The higher power, the less error.

There is a blog post which thoroughly analyses the matter: http://blog.shinetech.com/2014/02/17/the-beacon-experiments-low-energy-bluetooth-devices-in-action/

Author has a hypothesis that accuracy is actually distance. He claims that beacons from Kontakt.io are faulty beacuse when he increased power to the max value, accuracy value was very small for 1, 5 and even 15 meters. Before increasing power, accuracy was quite close to the distance values. I personally think that it's correct, because the higher power level, the less impact of interference. And it's strange why Estimote beacons don't behave this way.

I'm not saying I'm 100% right, but apart from being iOS developer I have degree in wireless electronics and I think that we shouldn't ignore "one sigma" term from docs and I would like to start discussion about it.

It may be possible that Apple's algorithm for accuracy just collects recent measurements and analyses the gaussian distribution of them. And that's how it sets accuracy. I wouldn't exclude possibility that they use info form accelerometer to detect whether user is moving (and how fast) in order to reset the previous distribution distance values because they have certainly changed.

I did it like this

CSS

html {
    -webkit-transition: background-color 1s;
    transition: background-color 1s;
}
html, body {
    /* For the loading indicator to be vertically centered ensure */
    /* the html and body elements take up the full viewport */
    min-height: 100%;
}
html.loading {
    /* Replace #333 with the background-color of your choice */
    /* Replace loading.gif with the loading image of your choice */
    background: #333 url('/Images/loading.gif') no-repeat 50% 50%;

    /* Ensures that the transition only runs in one direction */
    -webkit-transition: background-color 0;
    transition: background-color 0;
}
body {
    -webkit-transition: opacity 1s ease-in;
    transition: opacity 1s ease-in;
}
html.loading body {
    /* Make the contents of the body opaque during loading */
    opacity: 0;

    /* Ensures that the transition only runs in one direction */
    -webkit-transition: opacity 0;
    transition: opacity 0;
}

JS

$(document).ready(function () {
   $(document).ajaxStart(function () {     
       $("html").addClass("loading");
    });
    $(document).ajaxStop(function () {        
        $("html").removeClass("loading");
    });
    $(document).ajaxError(function () {       
        $("html").removeClass("loading");
    }); 
});

Just another way to do this:

=MID(A1, LEN(A1), 1)

You can create a RegExp object to make it a bit more readable

str.replace(new RegExp('/'), 'foobar');

If you want to replace all of them add the "g" flag

str.replace(new RegExp('/', 'g'), 'foobar');

This explains the whole thing:

The HTTP Content-Security-Policy (CSP) upgrade-insecure-requests directive instructs user agents to treat all of a site's insecure URLs (those served over HTTP) as though they have been replaced with secure URLs (those served over HTTPS). This directive is intended for web sites with large numbers of insecure legacy URLs that need to be rewritten.

The upgrade-insecure-requests directive is evaluated before block-all-mixed-content and if it is set, the latter is effectively a no-op. It is recommended to set one directive or the other, but not both.

The upgrade-insecure-requests directive will not ensure that users visiting your site via links on third-party sites will be upgraded to HTTPS for the top-level navigation and thus does not replace the Strict-Transport-Security (HSTS) header, which should still be set with an appropriate max-age to ensure that users are not subject to SSL stripping attacks.

Source: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy/upgrade-insecure-requests

let task = URLSession.shared.dataTask(with: request as URLRequest, completionHandler: { data,response,error in
        if error != nil{
            print(error!.localizedDescription)
            return
        }
        if let responseJSON = (try? JSONSerialization.jsonObject(with: data!, options: [])) as? [String:AnyObject]{
            if let response_token:String = responseJSON["token"] as? String {
                print("Singleton Firebase Token : \(response_token)")
                completion(response_token)
            }
        }
    })
    task.resume()

Thing I like to do is to wrap addition columns in aggregate function, like max(). It works very good when you don't expect duplicate values.

Select MAX(cpe.createdon) As MaxDate, cpe.fmgcms_cpeclaimid, MAX(cpe.fmgcms_claimid) As fmgcms_claimid 
from Filteredfmgcms_claimpaymentestimate cpe
where cpe.createdon < 'reportstartdate'
group by cpe.fmgcms_cpeclaimid

With my current reputation I have no ability to comment, so I choose answer referencing comments for sample code in reply by Prashant Gaur (thanks, Gaur - this was helpful!) - his sample is for python2, since python3 has no

unicode

The replacement below for function

get_prep_value(self, value):

encoding='utf-8', errors='ignore'

decode()

unicode() methods

errors='ignore'

import sys

...

    def get_prep_value(self, value):
        if value is None:
            return value
        if sys.version_info[0] >= 3:
            if isinstance(out_data, type(b'')):
                return value.decode(encoding='utf-8', errors='ignore')
        else:
            if isinstance(out_data, type(b'')):
                return unicode(value, encoding='utf-8', errors='ignore')
        return str(value)
...

Looks like the invisible character -

ALT+255

Try this

select REPLACE(ProductAlternateKey, ' ', '@')
--type ALT+255 instead of space for the second expression in REPLACE 
from DimProducts
where ProductAlternateKey  like '46783815%'

Raj

Edit: Based on ASCII() results, try ALT+10 - use numeric keypad

hi you can try doing this

link_to image_tag("Search.png", border: 0), {action: 'search', controller: 'pages'}, {class: 'dock-item'}

or even

link_to image_tag("Search.png", border: 0), {action: 'search', controller: 'pages'}, class: 'dock-item'

note that the position of the curly braces is very important, because if you miss them out, rails will assume they form a single hash parameters (read more about this here)

and according to the api for link_to:

link_to(name, options = {}, html_options = nil)

1. the first parameter is the string to be shown (or it can be an image_tag as well)
2. the second is the parameter for the url of the link
3. the last item is the optional parameter for declaring the html tag, e.g. class, onchange, etc.

hope it helps! =)

Well, the way to do it with simple parsing would be: get everything starting after the first = sign to the first & sign.

I think they had a similiar answer here:

Parsing a Vimeo ID using JavaScript?

Today we use Bearer token more often that Basic Authentication but if you want to have Basic Authentication first to get Bearer token then there is a couple ways:

const request = new XMLHttpRequest();
request.open('GET', url, false, username,password)
request.onreadystatechange = function() {
        // D some business logics here if you receive return
   if(request.readyState === 4 && request.status === 200) {
       console.log(request.responseText);
   }
}
request.send()

Full syntax is here

Second Approach using Ajax:

$.ajax
({
  type: "GET",
  url: "abc.xyz",
  dataType: 'json',
  async: false,
  username: "username",
  password: "password",
  data: '{ "key":"sample" }',
  success: function (){
    alert('Thanks for your up vote!');
  }
});

Hopefully, this provides you a hint where to start API calls with JS. In Frameworks like Angular, React, etc there are more powerful ways to make API call with Basic Authentication or Oauth Authentication. Just explore it.

Try

dexOptions {
    javaMaxHeapSize "4g"
    preDexLibraries = false
}

I don't know the reason. Something about preDexLibraries : https://sites.google.com/a/android.com/tools/tech-docs/new-build-system/tips

According to @lgdroid57 :

The following resource should help explain what this code does: link(http://google.github.io/android-gradle-dsl/current/com.android.build.gradle.internal.dsl.DexOptions.html) Property | Description javaMaxHeapSize | Sets the -JXmx* value when calling dx. Format should follow the 1024M pattern. preDexLibraries | Whether to pre-dex libraries. This can improve incremental builds, but clean builds may be slower.

If you want the basics, you can access the keys via:

string myKey = System.Configuration.ConfigurationManager.AppSettings["myKey"].ToString();
string imageFolder = System.Configuration.ConfigurationManager.AppSettings["imageFolder"].ToString();

To access my web config keys I always make a static class in my application. It means I can access them wherever I require and I'm not using the strings all over my application (if it changes in the web config I'd have to go through all the occurrences changing them). Here's a sample:

using System.Configuration;

public static class AppSettingsGet
{    
    public static string myKey
    {
        get { return ConfigurationManager.AppSettings["myKey"].ToString(); }
    }

    public static string imageFolder
    {
        get { return ConfigurationManager.AppSettings["imageFolder"].ToString(); }
    }

    // I also get my connection string from here
    public static string ConnectionString
    {
       get { return ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString; }
    }
}

This is how I come up with the IP

func ReadUserIP(r *http.Request) string {
    IPAddress := r.Header.Get("X-Real-Ip")
    if IPAddress == "" {
        IPAddress = r.Header.Get("X-Forwarded-For")
    }
    if IPAddress == "" {
        IPAddress = r.RemoteAddr
    }
    return IPAddress
}

• X-Real-Ip - fetches first true IP (if the requests sits behind multiple NAT sources/load balancer)

• X-Forwarded-For - if for some reason X-Real-Ip is blank and does not return response, get from X-Forwarded-For

• Remote Address - last resort (usually won't be reliable as this might be the last ip or if it is a naked http request to server ie no load balancer)

You can either post HTML form to URL, which is mapped to servlet or insert your data in HttpServletRequest object you pass to jsp page.

#!/usr/bin/perl -w
use strict;

my $url = $ARGV[0];
if($url =~ /([^:]*:\/\/)?([^\/]*\.)*([^\/\.]+)\.[^\/]+/g) {
  print $3;
}

You need to change it to a float BEFORE you do the division. That is:

float(20 - 10) / (100 - 10)

Given

    volumes:
      - /dir/on/host:/var/www/html

if /dir/on/host doesn't exist, it is created on the host and the empty content is mounted in the container at /var/www/html. Whatever content you had before in /var/www/html inside the container is inaccessible, until you unmount the volume; the new mount is hiding the old content.

public class StrongAES

    public void run() 
    {
        try 
        {
            String text = "Hello World";
            String key = "Bar12345Bar12345"; // 128 bit key
            // Create key and cipher
            Key aesKey = new SecretKeySpec(key.getBytes(), "AES");
            Cipher cipher = Cipher.getInstance("AES");
            // encrypt the text
            cipher.init(Cipher.ENCRYPT_MODE, aesKey);
            byte[] encrypted = cipher.doFinal(text.getBytes());
            System.err.println(new String(encrypted));
            // decrypt the text
            cipher.init(Cipher.DECRYPT_MODE, aesKey);
            String decrypted = new String(cipher.doFinal(encrypted));
            System.err.println(decrypted);
        }
        catch(Exception e) 
        {
            e.printStackTrace();
        }
    }
    public static void main(String[] args) 
    {
        StrongAES app = new StrongAES();
        app.run();
    }
}

I am using an older Data Structure and Algs book that comes with Java Applets for practice. So I needed to store and run some applets locally. I am currently running Windows 10 OS with Edge, Chrome, and IE 11.

Running applets seem to only be allowed in IE11, and as other have mentioned you have to add the applet to the exception list. My issue was since I am storing these locally, and opening them in IE, it opened with path starting with "C:\..." Adding the full path using, "file///..." like mentioned in one of the other answers didn't work for me.

The fix: So, I just added(without the quotes), "file:///" to the exception site list and finally got it working. This also allows me to run any applet stored locally, and I do not have to explicitly add an exception for each applet path.

I plan to remove the exception from the list once I am done using the programs, and only add it back as necessary.

In the specific case of a Rails action (as opposed to the general case of getting the current method name) you can use params[:action]

Alternatively you might want to look into customising the Rails log format so that the action/method name is included by the format rather than it being in your log message.

i just wrote a very fast solution by combining all knowledge gain above

    function pinger($address){
        if(strtolower(PHP_OS)=='winnt'){
            $command = "ping -n 1 $address";
            exec($command, $output, $status);
        }else{
            $command = "ping -c 1 $address";
            exec($command, $output, $status);
        }
        if($status === 0){
            return true;
        }else{
            return false;
        }
    }

Adding to the answer from E_8.
This does not work if you have empty strings.

You can get around this by modifying your select statement in SQL or modifying your query in the SSRS dataset.

 Select distinct phonenumber
from YourTable
where phonenumber <> ''
Order by Phonenumber

you use the scrollTop attribute

var position = document.getElementById('id').scrollTop;

Just by this (in your method in "methods"):

element = this.$el;

I have faced this issue and it fixed with following way:

1. first remove ng-app from:

   <html ng-app>
   

2. add name of ng-app to myApp:

   <div ng-app="myApp">
   

3. add this line of code before function:

   angular.module('myApp', []).controller('FirstCtrl',FirstCtrl);
   

final look of script:

angular.module('myApp', []).controller('FirstCtrl',FirstCtrl);

function FirstCtrl($scope){
    $scope.data = {message: "Hello"};
} 

After spending too much time on this issue and trying out all different answers, here is what found:

• The accepted answer by @thewaywewere is no longer applicable. I think this was applicable when opencv-python module still wasn't available.

• This is indeed a bug in Anaconda 4.2 because they forgot to ship python3.dll. They have fixed this in next releases but unfortunately 4.2 is the last release with Python 3.5 as default. If you are stuck with Python 3.5 (for example VS2015 is only aware of versions up to 3.5) then you must manually download python3.dll as described in answer by @Ramesh-X.

• If you can move on to Python 3.6 (which at present bit difficult if you are using OpenCV and VS2015) then just install latest Anaconda version and you don't have to deal with any of these.

Three steps needed:

1. Explicitly mark SSL2.0, TLS1.0, TLS1.1 as forbidden on your server machine, by adding Enabled=0 and DisabledByDefault=1 to your registry (the full path is HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols). See screen for details

2. Explicitly enable TLS1.2 by following the steps from 1. Just use Enabled=1 and DisabledByDefault=0 respectively.

NOTE: verify server version: Windows Server 2003 does not support the TLS 1.2 protocol

3. Enable TLS1.2 only on app level, like @John Wu suggested above.

   System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

Hope this guide helps.
