The problem is that they're all the same exact list in memory. When you use the [x]*n syntax, what you get is a list of n many x objects, but they're all references to the same object. They're not distinct instances, rather, just n references to the same instance.

To make a list of 3 different lists, do this:

x = [[] for i in range(3)]

This gives you 3 separate instances of [], which is what you want

[[]]*n is similar to

l = []
x = []
for i in range(n):
    x.append(l)

While [[] for i in range(3)] is similar to:

x = []
for i in range(n):
    x.append([])   # appending a new list!

In [20]: x = [[]] * 4

In [21]: [id(i) for i in x]
Out[21]: [164363948, 164363948, 164363948, 164363948] # same id()'s for each list,i.e same object


In [22]: x=[[] for i in range(4)]

In [23]: [id(i) for i in x]
Out[23]: [164382060, 164364140, 164363628, 164381292] #different id(), i.e unique objects this time

There are no cases where, given an array arr, that the value of sizeof(arr) / sizeof(arr[0]) is not the count of elements, by the definition of array and sizeof.

In fact, it's even directly mentioned (§5.3.3/2):

.... When applied to an array, the result is the total number of bytes in the array. This implies that the size of an array of n elements is n times the size of an element.

Emphasis mine. Divide by the size of an element, sizeof(arr[0]), to obtain n.

They're still types, so I always use the same naming conventions I use for classes.

I definitely would frown on putting "Class" or "Enum" in a name. If you have both a FruitClass and a FruitEnum then something else is wrong and you need more descriptive names. I'm trying to think about the kind of code that would lead to needing both, and it seems like there should be a Fruit base class with subtypes instead of an enum. (That's just my own speculation though, you may have a different situation than what I'm imagining.)

The best reference that I can find for naming constants comes from the Variables tutorial:

If the name you choose consists of only one word, spell that word in all lowercase letters. If it consists of more than one word, capitalize the first letter of each subsequent word. The names gearRatio and currentGear are prime examples of this convention. If your variable stores a constant value, such as static final int NUM_GEARS = 6, the convention changes slightly, capitalizing every letter and separating subsequent words with the underscore character. By convention, the underscore character is never used elsewhere.

There is not official api support which means that it is not documented for the public and the libraries may change at any time. I realize you don't want to leave the application but here's how you do it with an intent for anyone else wondering.

public void sendData(int num){
    String fileString = "..."; //put the location of the file here
    Intent mmsIntent = new Intent(Intent.ACTION_SEND);
    mmsIntent.putExtra("sms_body", "text");
    mmsIntent.putExtra("address", num);
    mmsIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(new File(fileString)));
    mmsIntent.setType("image/jpeg");
    startActivity(Intent.createChooser(mmsIntent, "Send"));

}

I haven't completely figured out how to do things like track the delivery of the message but this should get it sent.

You can be alerted to the receipt of mms the same way as sms. The intent filter on the receiver should look like this.

<intent-filter>
    <action android:name="android.provider.Telephony.WAP_PUSH_RECEIVED" />
    <data android:mimeType="application/vnd.wap.mms-message" />
</intent-filter>

I am going to answer my own question.

I added the following lines of code to my Makefile and it fixed the "clock skew" problem:

clean:  
    find . -type f | xargs touch
    rm -rf $(OBJS)

In addition to being able to add a number of days to a date, you can use interval data types assuming you are on Oracle 9i or later, which can be somewhat easier to read,

Here is the Complete solution

#First Datasource (DB1)
db1.datasource.url: url
db1.datasource.username:user
db1.datasource.password:password

#Second Datasource (DB2)
db2.datasource.url:url
db2.datasource.username:user
db2.datasource.password:password

Since we are going to get access two different databases (db1, db2), we need to configure each data source configuration separately like:

public class DB1_DataSource {
@Autowired
private Environment env;
@Bean
@Primary
public LocalContainerEntityManagerFactoryBean db1EntityManager() {
    LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
    em.setDataSource(db1Datasource());
    em.setPersistenceUnitName("db1EntityManager");
    HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
    em.setJpaVendorAdapter(vendorAdapter);
    HashMap<string, object=""> properties = new HashMap<>();
    properties.put("hibernate.dialect",
            env.getProperty("hibernate.dialect"));
    properties.put("hibernate.show-sql",
            env.getProperty("jdbc.show-sql"));
    em.setJpaPropertyMap(properties);
    return em;
}

@Primary
@Bean
public DataSource db1Datasource() {

    DriverManagerDataSource dataSource
            = new DriverManagerDataSource();
    dataSource.setDriverClassName(
            env.getProperty("jdbc.driver-class-name"));
    dataSource.setUrl(env.getProperty("db1.datasource.url"));
    dataSource.setUsername(env.getProperty("db1.datasource.username"));
    dataSource.setPassword(env.getProperty("db1.datasource.password"));

    return dataSource;
}

@Primary
@Bean
public PlatformTransactionManager db1TransactionManager() {

    JpaTransactionManager transactionManager
            = new JpaTransactionManager();
    transactionManager.setEntityManagerFactory(
            db1EntityManager().getObject());
    return transactionManager;
}
}

Second Datasource :

public class DB2_DataSource {

@Autowired
private Environment env;

@Bean
public LocalContainerEntityManagerFactoryBean db2EntityManager() {
    LocalContainerEntityManagerFactoryBean em
            = new LocalContainerEntityManagerFactoryBean();
    em.setDataSource(db2Datasource());
    em.setPersistenceUnitName("db2EntityManager");
    HibernateJpaVendorAdapter vendorAdapter
            = new HibernateJpaVendorAdapter();
    em.setJpaVendorAdapter(vendorAdapter);
    HashMap<string, object=""> properties = new HashMap<>();
    properties.put("hibernate.dialect",
            env.getProperty("hibernate.dialect"));
    properties.put("hibernate.show-sql",
            env.getProperty("jdbc.show-sql"));
    em.setJpaPropertyMap(properties);
    return em;
}

@Bean
public DataSource db2Datasource() {
    DriverManagerDataSource dataSource
            = new DriverManagerDataSource();
    dataSource.setDriverClassName(
            env.getProperty("jdbc.driver-class-name"));
    dataSource.setUrl(env.getProperty("db2.datasource.url"));
    dataSource.setUsername(env.getProperty("db2.datasource.username"));
    dataSource.setPassword(env.getProperty("db2.datasource.password"));

    return dataSource;
}

@Bean
public PlatformTransactionManager db2TransactionManager() {
    JpaTransactionManager transactionManager
            = new JpaTransactionManager();
    transactionManager.setEntityManagerFactory(
            db2EntityManager().getObject());
    return transactionManager;
}
}

A workaround is to get the fileId with Google Drive SDK API and then using this Url:

https://drive.google.com/uc?export=view&id={fileId}

That will be a permanent link to your file in Google Drive (image or anything else).

Note: this link seems to be subject to quotas. So not ideal for public/massive sharing.

Sounds like you need to add the formatting to the WHERE:

SELECT users.id, DATE_FORMAT(users.signup_date, '%Y-%m-%d') 
FROM users 
WHERE DATE_FORMAT(users.signup_date, '%Y-%m-%d') = CURDATE()

See SQL Fiddle with Demo

I use

file_age() {
    local filename=$1
    echo $(( $(date +%s) - $(date -r $filename +%s) ))
}

is_stale() {
    local filename=$1
    local max_minutes=20
    [ $(file_age $filename) -gt $(( $max_minutes*60 )) ]
}

if is_stale /my/file; then
    ...
fi

Use command substitution instead of quotes to execute find instead of passing the command as a string:

for line in $(find . -iname '*.txt'); do 
     echo $line
     ls -l $line; 
done

Primitives vs. References

First :-

Primitive types are the basic types of data: byte, short, int, long, float, double, boolean, char. Primitive variables store primitive values. Reference types are any instantiable class as well as arrays: String, Scanner, Random, Die, int[], String[], etc. Reference variables store addresses to locations in memory for where the data is stored.

Second:-

Primitive types store values but Reference type store handles to objects in heap space. Remember, reference variables are not pointers like you might have seen in C and C++, they are just handles to objects, so that you can access them and make some change on object's state.

        relativeUrl = VirtualPathUtility.ToAbsolute(relativeUrl);

I suppose you are using a LinearLayoutManager to show the list. It has a nice method called findViewByPosition that

Finds the view which represents the given adapter position.

All you need is the adapter position of the item you are interested in.

edit: as noted by Paul Woitaschek in the comments, findViewByPosition is a method of LayoutManager so it would work with all LayoutManagers (i.e. StaggeredGridLayoutManager, etc.)

Absolutely position divs over the text area with a z-index higher and give these divs a transparent GIF background graphic.

Note after a bit more thought - You'd need to have these 'covers' be linked so clicking on them would take you to where the tab was supposed to, which means you could/should do this with the anchor element set to display:box, width and height set as well as the transparent background image.

First of all, for initializing a container you cannot use a primitive type (i.e. int; you can use int[] but as you want just an array of integers, I see no use in that). Instead, you should use Integer, as follows:

ArrayList<Integer> arl = new ArrayList<Integer>();

For adding elements, just use the add function:

arl.add(1);  
arl.add(22);
arl.add(-2);

Last, but not least, for printing the ArrayList you may use the build-in functionality of toString():

System.out.println("Arraylist contains: " + arl.toString());  

If you want to access the i element, where i is an index from 0 to the length of the array-1, you can do a :

int i = 0; // Index 0 is of the first element
System.out.println("The first element is: " + arl.get(i));

I suggest reading first on Java Containers, before starting to work with them.

You can simply use setInterval utility and use arrow function as callback so that this will point to the component instance.

For ex:

this.interval = setInterval( () => { 
    // call your functions like 
    this.getList();
    this.updateInfo();
});

Inside your ngOnDestroy lifecycle hook, clear the interval.

ngOnDestroy(){
    clearInterval(this.interval);
}

One option is to directly input the character you're interested in using hex or octal notation:

printf "\x41\n"
printf "\101\n"

Your choofdlog holds a FileName and FileNames (for multi-selection) containing the file paths, after the ShowDialog() returns.

Third solution: I would set ws to a sheet of workbook wb as the use of Sheet("name") always refers to the active workbook, which might change as your code develops.

sub kl() 

    Dim wb As Workbook
    Dim ws As Worksheet

    Set wb = ActiveWorkbook
    'be aware as this might produce an error, if Shet "name" does not exist
    Set ws = wb.Sheets("name")
    ' if wb is other than the active workbook
    wb.activate
    ws.Select

End Sub

• To run https functionality or SSL authentication in flask application you first install "pyOpenSSL" python package using:

   pip install pyopenssl
  

• Next step is to create 'cert.pem' and 'key.pem' using following command on terminal :

   openssl req -x509 -newkey rsa:4096 -nodes -out cert.pem -keyout key.pem -days 365
  

• Copy generated 'cert.pem' and 'kem.pem' in you flask application project

• Add ssl_context=('cert.pem', 'key.pem') in app.run()

For example:

    from flask import Flask, jsonify

    app = Flask(__name__)

    @app.route('/')

    def index():

        return 'Flask is running!'


    @app.route('/data')

    def names():

        data = {"names": ["John", "Jacob", "Julie", "Jennifer"]}

        return jsonify(data)

  if __name__ == '__main__':

        app.run(ssl_context=('cert.pem', 'key.pem'))

The problem you're having stems from the fact that you're missing android:dividerHeight, which you need, and the fact that you're trying to specify a line weight in your drawable, which you can't do with dividers for some odd reason. Essentially to get your example to work you could do something like the following:

Create your drawable as either a rectangle or a line, either works you just can't try to set any dimensions on it, so either:

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="line">
     <stroke android:color="#8F8F8F" android:dashWidth="1dp" android:dashGap="1dp" />
</shape>

OR:

<shape xmlns:android="http://schemas.android.com/apk/res/android"  android:shape="rectangle">
     <solid android:color="#8F8F8F"/>
</shape>

Then create a custom style (just a preference but I like to be able to reuse stuff)

<style name="dividedListStyle" parent="@android:style/Widget.ListView">
    <item name="android:cacheColorHint">@android:color/transparent</item>
    <item name="android:divider">@drawable/list_divider</item>
    <item name="android:dividerHeight">1dp</item>
</style>

Finally declare your list view using the custom style:

<ListView
     style="@style/dividedListStyle"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:id="@+id/cashItemsList">
</ListView>

I'm assuming you know how to use these snippets, if not let me know. Basically the answer to your question is that you can't set the divider thickness in the drawable, you have to leave the width undefined there and use android:dividerHeight to set it instead.

Also make sure the value is not too large or too small for int like in my case.

You have not defined a method around your code.

import java.io.*;

public class details
{
    public static void main( String[] args )
    {
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("What is your name?");
        String name = in.readLine(); ;
        System.out.println("Hello " + name);
    }
}

In this case, I have assumed that you want your code to be executed in the main method of the class. It is, of course, possible that this code goes in any other method.

adb backup will write an Android-specific archive:

adb backup  -f myAndroidBackup.ab  com.corp.appName

This archive can be converted to tar format using:

dd if=myAndroidBackup.ab bs=4K iflag=skip_bytes skip=24 | openssl zlib -d > myAndroidBackup.tar

Reference:

Search for "Update" at that link.

Alternatively, use Android backup extractor to extract files from the Android backup (.ab) file.

    $(this).unbind('click');
});

but it would cause a lot of overhead

Considering that you already have a full backup I’d just restore that backup into separate database and migrate the data from there.

If your data has changed after the latest backup then what you recover all data that way but you can try to recover that by reading transaction log.

If your database was in full recovery mode than transaction log has enough details to recover updates to your data after the latest backup.

You might want to try with DBCC LOG, fn_log functions or with third party log reader such as ApexSQL Log

Unfortunately there is no easy way to read transaction log because MS doesn’t provide documentation for this and stores the data in its proprietary format.

Position the div relatively, and position the ribbon absolutely inside it. Something like:

#content {
  position:relative;
}

.ribbon {
  position:absolute;
  top:0;
  right:0;
}

Using only base, I wrote the following function.

Note:

1. Assumes Mon is day number 1 in the week
2. First week is week 1
3. Returns 0 if week is 52 from last year

Fine-tune to suit your needs.

findWeekNo <- function(myDate){
  # Find out the start day of week 1; that is the date of first Mon in the year
  weekday <- switch(weekdays(as.Date(paste(format(as.Date(myDate),"%Y"),"01-01", sep = "-"))),
                    "Monday"={1},
                    "Tuesday"={2},
                    "Wednesday"={3},
                    "Thursday"={4},
                    "Friday"={5},
                    "Saturday"={6},
                    "Sunday"={7}
  )

  firstMon <- ifelse(weekday==1,1, 9 - weekday )

  weekNo <- floor((as.POSIXlt(myDate)$yday - (firstMon-1))/7)+1
  return(weekNo)
}


findWeekNo("2017-01-15") # 2

Perhaps you could try passing location into the component as a prop. Below I use ...otherProps. This is the spread operator, and is valid but unneccessary if you passed in your props explicitly it's just there as a place holder for demonstration purposes. Also, research destructuring to understand where ({ location }) came from.

import React from 'react';
import withRouter from 'react-router-dom';

const MyComponent = ({ location, ...otherProps }) => (whatever you want to render)


export withRouter(MyComponent);

If it is just about the color and there is no specific need for JavaScript, you could also convert them to a font. This link gives you an opportunity to create a font based on the SVG. However, it is not possible to use img attributes afterwards - like "alt". This also limits the accessibility of your website for blind people and so on.

What is the difference between NULL, ‘\0’ and 0

"null character (NUL)" is easiest to rule out. '\0' is a character literal. In C, it is implemented as int, so, it's the same as 0, which is of INT_TYPE_SIZE. In C++, character literal is implemented as char, which is 1 byte. This is normally different from NULL or 0.

Next, NULL is a pointer value that specifies that a variable does not point to any address space. Set aside the fact that it is usually implemented as zeros, it must be able to express the full address space of the architecture. Thus, on a 32-bit architecture NULL (likely) is 4-byte and on 64-bit architecture 8-byte. This is up to the implementation of C.

Finally, the literal 0 is of type int, which is of size INT_TYPE_SIZE. The default value of INT_TYPE_SIZE could be different depending on architecture.

The 64-bit data model used by Mac OS X is known as "LP64". This is the common data model used by other 64-bit UNIX systems from Sun and SGI as well as 64-bit Linux. The LP64 data model defines the primitive types as follows:

• ints are 32-bit
• longs are 64-bit
• long-longs are also 64-bit
• pointers are 64-bit

There's little wrong with using array_intersect() and count() (instead of empty).

For example:

$bFound = (count(array_intersect($criminals, $people))) ? true : false;

If you install MySQL via homebrew on MacOS, you might need to delete your old data directory /usr/local/var/mysql. Otherwise, it will fail during the initialization process with the following error:

All standard implementations of java.util.List already implement java.io.Serializable.

So even though java.util.List itself is not a subtype of java.io.Serializable, it should be safe to cast the list to Serializable, as long as you know it's one of the standard implementations like ArrayList or LinkedList.

If you're not sure, then copy the list first (using something like new ArrayList(myList)), then you know it's serializable.

This is much easier:

<textarea onKeyPress="return ( this.value.length < 1000 );"></textarea>

You can use bellow code example for date string like mdate and Now() like toDay, you can also calculate deference between both date like Aging

Public Sub test(mdate As String)
    Dim toDay As String
    mdate = Round(CDbl(CDate(mdate)), 0)
    toDay = Round(CDbl(Now()), 0)
    Dim Aging as String
    Aging = toDay - mdate
    MsgBox ("So aging is -" & Aging & vbCr & "from the date - " & _
    Format(mdate, "dd-mm-yyyy")) & " to " & Format(toDay, "dd-mm-yyyy"))
End Sub

NB: Used CDate for convert Date String to Valid Date

I am using this in Office 2007 :)

Whenever you do a basic web search for random number generation in the C++ programming language this question is usually the first to pop up! I want to throw my hat into the ring to hopefully better clarify the concept of pseudo-random number generation in C++ for future coders that will inevitably search this same question on the web!

The Basics

Pseudo-random number generation involves the process of utilizing a deterministic algorithm that produces a sequence of numbers whose properties approximately resemble random numbers. I say approximately resemble, because true randomness is a rather elusive mystery in mathematics and computer science. Hence, why the term pseudo-random is utilized to be more pedantically correct!

Before you can actually use a PRNG, i.e., pseudo-random number generator, you must provide the algorithm with an initial value often referred too as the seed. However, the seed must only be set once before using the algorithm itself!

/// Proper way!
seed( 1234 ) /// Seed set only once...
for( x in range( 0, 10) ):
  PRNG( seed ) /// Will work as expected

/// Wrong way!
for( x in rang( 0, 10 ) ):
  seed( 1234 ) /// Seed reset for ten iterations!
  PRNG( seed ) /// Output will be the same...

Thus, if you want a good sequence of numbers, then you must provide an ample seed to the PRNG!

The Old C Way

The backwards compatible standard library of C that C++ has, uses what is called a linear congruential generator found in the cstdlib header file! This PRNG functions through a discontinuous piecewise function that utilizes modular arithmetic, i.e., a quick algorithm that likes to use the modulo operator '%'. The following is common usage of this PRNG, with regards to the original question asked by @Predictability:

#include <iostream>
#include <cstdlib>
#include <ctime>

int main( void )
{
  int low_dist  = 1;
  int high_dist = 6;
  std::srand( ( unsigned int )std::time( nullptr ) );
  for( int repetition = 0; repetition < 10; ++repetition )
    std::cout << low_dist + std::rand() % ( high_dist - low_dist ) << std::endl;
  return 0;
}

The common usage of C's PRNG houses a whole host of issues such as:

1. The overall interface of std::rand() isn't very intuitive for the proper generation of pseudo-random numbers between a given range, e.g., producing numbers between [1, 6] the way @Predictability wanted.
2. The common usage of std::rand() eliminates the possibility of a uniform distribution of pseudo-random numbers, because of the Pigeonhole Principle.
3. The common way std::rand() gets seeded through std::srand( ( unsigned int )std::time( nullptr ) ) technically isn't correct, because time_t is considered to be a restricted type. Therefore, the conversion from time_t to unsigned int is not guaranteed!

For more detailed information about the overall issues of using C's PRNG, and how to possibly circumvent them, please refer to Using rand() (C/C++): Advice for the C standard library’s rand() function!

The Standard C++ Way

Since the ISO/IEC 14882:2011 standard was published, i.e., C++11, the random library has been apart of the C++ programming language for a while now. This library comes equipped with multiple PRNGs, and different distribution types such as: uniform distribution, normal distribution, binomial distribution, etc. The following source code example demonstrates a very basic usage of the random library, with regards to @Predictability's original question:

#include <iostream>
#include <cctype>
#include <random>

using u32    = uint_least32_t; 
using engine = std::mt19937;

int main( void )
{
  std::random_device os_seed;
  const u32 seed = os_seed();

  engine generator( seed );
  std::uniform_int_distribution< u32 > distribute( 1, 6 );

  for( int repetition = 0; repetition < 10; ++repetition )
    std::cout << distribute( generator ) << std::endl;
  return 0;
}

The 32-bit Mersenne Twister engine, with a uniform distribution of integer values was utilized in the above example. (The name of the engine in source code sounds weird, because its name comes from its period of 2^19937-1 ). The example also uses std::random_device to seed the engine, which obtains its value from the operating system (If you are using a Linux system, then std::random_device returns a value from /dev/urandom).

Take note, that you do not have to use std::random_device to seed any engine. You can use constants or even the chrono library! You also don't have to use the 32-bit version of the std::mt19937 engine, there are other options! For more information about the capabilities of the random library, please refer to cplusplus.com

All in all, C++ programmers should not use std::rand() anymore, not because its bad, but because the current standard provides better alternatives that are more straight forward and reliable. Hopefully, many of you find this helpful, especially those of you who recently web searched generating random numbers in c++!

Am I missing something? You can just convert offer_date in the comparison:

SELECT *
FROM offers
WHERE to_char(offer_date, 'YYYYMM') = (SELECT to_date(create_date, 'YYYYMM') FROM customers where id = '12345678') AND
      offer_rate > 0 

I have tried both of online jsbeautifier(jsbeautifier, jsnice), these tools gave me beautiful js code,

but couldn't copy for very large js (must be bug, when i copy, copied buffer contains only one character '-').

I found that only working solution was prettyjs:

I believe this should work fine for any DataFrame columns list.

def column_list(x):
    column_list_df = []
    for col_name in x.columns:
        y = col_name, len(x[col_name].unique())
        column_list_df.append(y)
return pd.DataFrame(column_list_df)

column_list_df.rename(columns={0: "Feature", 1: "Value_count"})

The function "column_list" checks the columns names and then checks the uniqueness of each column values.

$pdf->Output() takes a second parameter $dest, which accepts a single character. The default, $dest='I' opens the PDF in the browser.

Use F to save to file

$pdf->Output('/path/to/file.pdf', 'F')

If you need to do this on the backend you can use the following URL structure:

https://maps.googleapis.com/maps/api/geocode/json?address=[STREET_ADDRESS]&key=[YOUR_API_KEY]

Sample PHP code using curl:

$curl = curl_init();

curl_setopt($curl, CURLOPT_URL, 'https://maps.googleapis.com/maps/api/geocode/json?address=' . rawurlencode($address) . '&key=' . $api_key);

curl_setopt ($curl, CURLOPT_RETURNTRANSFER, 1);

$json = curl_exec($curl);

curl_close ($curl);

$obj = json_decode($json);

See additional documentation for more details and expected json response.

The docs provide sample output and will assist you in getting your own API key in order to be able to make requests to the Google Maps Geocoding API.

If your close button is going to be text, this works very well for me:

#close {
  position: fixed;
  width: 70%; /* the width of the parent */
  text-align: right;
}
#close span {
  cursor: pointer;
}

Then your HTML can just be:

<div id="close"><span id="x">X</span></div>

Use Jquery functions

<Button id="myPselector" data-id="1234">HI</Button> 
console.log($("#myPselector").attr('data-id'));

SonarQube documentation recommends adding static keyword to the class declaration.

That is, change public class FilePathHelper to public static class FilePathHelper.

Alternatively you can add a private or protected constructor.

public class FilePathHelper
{
    // private or protected constructor
    // because all public fields and methods are static
    private FilePathHelper() {
    }
}

I was searching for a solution to get the last foldername where the file is located, I just used split two times, to get the right part. It's not the question but google transfered me here.

pathname = "/folderA/folderB/folderC/folderD/filename.py"
head, tail = os.path.split(os.path.split(pathname)[0])
print(head + "   "  + tail)

Another method for creating a JavaScript associative array

First create an array of objects,

 var arr = {'name': []};

Next, push the value to the object.

  var val = 2;
  arr['name'].push(val);

To read from it:

var val = arr.name[0];

In the ListBox DoubleClick event get the selecteditem(s) member of the listbox, and there you are.

void ListBox1DoubleClick(object sender, EventArgs e)
    {
        MessageBox.Show(string.Format("SelectedItem:\n{0}",listBox1.SelectedItem.ToString()));
    }

Implement custom adapter for your class:

public class MyClassAdapter extends ArrayAdapter<MyClass> {

    private static class ViewHolder {
        private TextView itemView;
    }

    public MyClassAdapter(Context context, int textViewResourceId, ArrayList<MyClass> items) {
        super(context, textViewResourceId, items);
    }

    public View getView(int position, View convertView, ViewGroup parent) {

        if (convertView == null) {
            convertView = LayoutInflater.from(this.getContext())
            .inflate(R.layout.listview_association, parent, false);

            viewHolder = new ViewHolder();
            viewHolder.itemView = (TextView) convertView.findViewById(R.id.ItemView);

            convertView.setTag(viewHolder);
        } else {
            viewHolder = (ViewHolder) convertView.getTag();
        }

        MyClass item = getItem(position);
        if (item!= null) {
            // My layout has only one TextView
                // do whatever you want with your string and long
            viewHolder.itemView.setText(String.format("%s %d", item.reason, item.long_val));
        }

        return convertView;
    }
}

For those not very familiar with the Android framework, this is explained in better detail here: https://github.com/codepath/android_guides/wiki/Using-an-ArrayAdapter-with-ListView.

Precision and scale are often misunderstood. In numeric(3,2) you want 3 digits overall, but 2 to the right of the decimal. If you want 15 => 15.00 so the leading 1 causes the overflow (since if you want 2 digits to the right of the decimal, there is only room on the left for one more digit). With 4,2 there is no problem because all 4 digits fit.

Well, I was trying to obtain the same effect without resorting to fixed size columns or having a fixed height for the entire table.

The solution I came up with is a hack. It consists of duplicating the entire table then hiding everything but the header, and making that have a fixed position.

HTML

<div id="table-container">
<table id="maintable">
    <thead>
        <tr>
            <th>Col1</th>
            <th>Col2</th>
            <th>Col3</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>info</td>
            <td>info</td>
            <td>info</td>
        </tr>
        <tr>
            <td>info</td>
            <td>info</td>
            <td>info</td>
        </tr>
        <tr>
            <td>info</td>
            <td>some really long line here instead</td>
            <td>info</td>
        </tr>
        <tr>
            <td>info</td>
            <td>info</td>
            <td>info</td>
        </tr>
                <tr>
            <td>info</td>
            <td>info</td>
            <td>info</td>
        </tr>
                <tr>
            <td>info</td>
            <td>info</td>
            <td>info</td>
        </tr>
        <tr>
            <td>info</td>
            <td>info</td>
            <td>info</td>
        </tr>
    </tbody>
</table>
<div id="bottom_anchor"></div>

CSS

body { height: 1000px; }

javascript

function moveScroll(){
    var scroll = $(window).scrollTop();
    var anchor_top = $("#maintable").offset().top;
    var anchor_bottom = $("#bottom_anchor").offset().top;
    if (scroll>anchor_top && scroll<anchor_bottom) {
    clone_table = $("#clone");
    if(clone_table.length == 0){
        clone_table = $("#maintable").clone();
        clone_table.attr('id', 'clone');
        clone_table.css({position:'fixed',
                 'pointer-events': 'none',
                 top:0});
        clone_table.width($("#maintable").width());
        $("#table-container").append(clone_table);
        $("#clone").css({visibility:'hidden'});
        $("#clone thead").css({'visibility':'visible','pointer-events':'auto'});
    }
    } else {
    $("#clone").remove();
    }
}
$(window).scroll(moveScroll); 

See here: http://jsfiddle.net/QHQGF/7/

Edit: updated the code so that the thead can receive pointer events(so buttons and links in the header still work). This fixes the problem reported by luhfluh and Joe M.

New jsfiddle here: http://jsfiddle.net/cjKEx/

A reproducible example:

the_plot <- function()
{
  x <- seq(0, 1, length.out = 100)
  y <- pbeta(x, 1, 10)
  plot(
    x,
    y,
    xlab = "False Positive Rate",
    ylab = "Average true positive rate",
    type = "l"
  )
}

James's suggestion of using pointsize, in combination with the various cex parameters, can produce reasonable results.

png(
  "test.png",
  width     = 3.25,
  height    = 3.25,
  units     = "in",
  res       = 1200,
  pointsize = 4
)
par(
  mar      = c(5, 5, 2, 2),
  xaxs     = "i",
  yaxs     = "i",
  cex.axis = 2,
  cex.lab  = 2
)
the_plot()
dev.off()

Of course the better solution is to abandon this fiddling with base graphics and use a system that will handle the resolution scaling for you. For example,

library(ggplot2)

ggplot_alternative <- function()
{
  the_data <- data.frame(
    x <- seq(0, 1, length.out = 100),
    y = pbeta(x, 1, 10)
  )

ggplot(the_data, aes(x, y)) +
    geom_line() +
    xlab("False Positive Rate") +
    ylab("Average true positive rate") +
    coord_cartesian(0:1, 0:1)
}

ggsave(
  "ggtest.png",
  ggplot_alternative(),
  width = 3.25,
  height = 3.25,
  dpi = 1200
)

None of the above solutions worked for me what did work however is

function validDate (d) {
    var date = new Date(d);
    var day = "" + date.getDate();
    if ( day.length == 1 ) day = "0" + day;
    var month = "" + (date.getMonth() + 1);
    if ( month.length == 1 ) month = "0" + month;
    var year = "" + date.getFullYear();
    return (( month + "/" + day + "/" + year ) == d );
}

the code above will see when JS makes 02/31/2012 into 03/02/2012 that it's not valid

What we do, is to create two tables for each multilingual object.

E.g. the first table contains only language-neutral data (primary key, etc.) and the second table contains one record per language, containing the localized data plus the ISO code of the language.

In some cases we add a DefaultLanguage field, so that we can fall-back to that language if no localized data is available for a specified language.

Example:

Table "Product":
----------------
ID                 : int
<any other language-neutral fields>


Table "ProductTranslations"
---------------------------
ID                 : int      (foreign key referencing the Product)
Language           : varchar  (e.g. "en-US", "de-CH")
IsDefault          : bit
ProductDescription : nvarchar
<any other localized data>

With this approach, you can handle as many languages as needed (without having to add additional fields for each new language).

Update (2014-12-14): please have a look at this answer, for some additional information about the implementation used to load multilingual data into an application.

Simplest solution

Use numpy.dot or a.dot(b). See the documentation here.

>>> a = np.array([[ 5, 1 ,3], 
                  [ 1, 1 ,1], 
                  [ 1, 2 ,1]])
>>> b = np.array([1, 2, 3])
>>> print a.dot(b)
array([16, 6, 8])

This occurs because numpy arrays are not matrices, and the standard operations *, +, -, / work element-wise on arrays. Instead, you could try using numpy.matrix, and * will be treated like matrix multiplication.

Other Solutions

Also know there are other options:

• As noted below, if using python3.5+ the @ operator works as you'd expect:

  >>> print(a @ b)
  array([16, 6, 8])
  

• If you want overkill, you can use numpy.einsum. The documentation will give you a flavor for how it works, but honestly, I didn't fully understand how to use it until reading this answer and just playing around with it on my own.

  >>> np.einsum('ji,i->j', a, b)
  array([16, 6, 8])
  

• As of mid 2016 (numpy 1.10.1), you can try the experimental numpy.matmul, which works like numpy.dot with two major exceptions: no scalar multiplication but it works with stacks of matrices.

  >>> np.matmul(a, b)
  array([16, 6, 8])
  

• numpy.inner functions the same way as numpy.dot for matrix-vector multiplication but behaves differently for matrix-matrix and tensor multiplication (see Wikipedia regarding the differences between the inner product and dot product in general or see this SO answer regarding numpy's implementations).

  >>> np.inner(a, b)
  array([16, 6, 8])
  
  # Beware using for matrix-matrix multiplication though!
  >>> b = a.T
  >>> np.dot(a, b)
  array([[35,  9, 10],
         [ 9,  3,  4],
         [10,  4,  6]])
  >>> np.inner(a, b) 
  array([[29, 12, 19],
         [ 7,  4,  5],
         [ 8,  5,  6]])
  

Rarer options for edge cases

• If you have tensors (arrays of dimension greater than or equal to one), you can use numpy.tensordot with the optional argument axes=1:

  >>> np.tensordot(a, b, axes=1)
  array([16,  6,  8])
  

• Don't use numpy.vdot if you have a matrix of complex numbers, as the matrix will be flattened to a 1D array, then it will try to find the complex conjugate dot product between your flattened matrix and vector (which will fail due to a size mismatch n*m vs n).

There are multiple syntaxes for multi-line strings as you've already read. My favorite is Perl-style:

conn.exec %q{select attr1, attr2, attr3, attr4, attr5, attr6, attr7
      from table1, table2, table3, etc, etc, etc, etc, etc,
      where etc etc etc etc etc etc etc etc etc etc etc etc etc}

The multi-line string starts with %q, followed by a {, [ or (, and then terminated by the corresponding reversed character. %q does not allow interpolation; %Q does so you can write things like this:

conn.exec %Q{select attr1, attr2, attr3, attr4, attr5, attr6, attr7
      from #{table_names},
      where etc etc etc etc etc etc etc etc etc etc etc etc etc}

I actually have no idea how these kinds of multi-line strings are called so let's just call them Perl multilines.

Note however that whether you use Perl multilines or heredocs as Mark and Peter have suggested, you'll end up with potentially unnecessary whitespaces. Both in my examples and their examples, the "from" and "where" lines contain leading whitespaces because of their indentation in the code. If this whitespace is not desired then you must use concatenated strings as you are doing now.

You can use

timestamp=`date --rfc-3339=seconds`

This delivers in the format 2014-02-01 15:12:35-05:00

The back-tick (`) characters will cause what is between them to be evaluated and have the result included in the line. date --help has other options.

I am getting the error (...) javax.naming.NameNotFoundException: greetJndi not bound

This means that nothing is bound to the jndi name greetJndi, very likely because of a deployment problem given the incredibly low quality of this tutorial (check the server logs). I'll come back on this.

Is there any specific directory structure to deploy in JBoss?

The internal structure of the ejb-jar is supposed to be like this (using the poor naming conventions and the default package as in the mentioned link):

.
+-- greetBean.java
+-- greetHome.java
+-- greetRemote.java
+-- META-INF
    +-- ejb-jar.xml
    +-- jboss.xml

But as already mentioned, this tutorial is full of mistakes:

• there is an extra character (<enterprise-beans>] <-- HERE) in the ejb-jar.xml (!)
• a space is missing after PUBLIC in the ejb-jar.xml and jboss.xml (!!)
• the jboss.xml is incorrect, it should contain a session element instead of entity (!!!)

Here is a "fixed" version of the ejb-jar.xml:

After doing these changes and repackaging the ejb-jar, I was able to successfully deploy it:

That tutorial needs significant improvement; I'd advise from staying away from roseindia.net.

Well Curl could be a better option for json representation but in that case it would be difficult to understand the structure of json because its in command line. if you want to get your json on browser you simply remove all the XML Annotations like -

@XmlRootElement(name="person")
@XmlAccessorType(XmlAccessType.NONE)
@XmlAttribute
@XmlElement

from your model class and than run the same url, you have used for xml representation.

Make sure that you have jacson-databind dependency in your pom.xml

<dependency>
  <groupId>com.fasterxml.jackson.core</groupId>
  <artifactId>jackson-databind</artifactId>
  <version>2.4.1</version>
</dependency>

Maybe this will help.

var inputVal = $(this).closest('tr').find("td:eq(x) input").val();

Protect by:

$ip=$_SERVER['REMOTE_ADDER'];
$_SESSEION['ip']=$ip;

It looks like you're using python 3.x. In python3, filter, map, zip, etc return an object which is iterable, but not a list. In other words,

filter(func,data) #python 2.x

is equivalent to:

list(filter(func,data)) #python 3.x

I think it was changed because you (often) want to do the filtering in a lazy sense -- You don't need to consume all of the memory to create a list up front, as long as the iterator returns the same thing a list would during iteration.

If you're familiar with list comprehensions and generator expressions, the above filter is now (almost) equivalent to the following in python3.x:

( x for x in data if func(x) ) 

As opposed to:

[ x for x in data if func(x) ]

in python 2.x

from learnyounode:

var http = require('http')
var bl = require('bl')

http.get(process.argv[2], function (response) {
    response.pipe(bl(function (err, data) {
        if (err)
            return console.error(err)
        data = data.toString()
        console.log(data)
    }))
})

WCF = Windows COMMUNICATION Foundation

WPF = Windows PRESENTATION Foundation.

WCF deals with communication (in simple terms - sending and receiving data as well as formatting and serialization involved), WPF deals with presentation (UI)

The above-mentioned responses work well but if you want to pass data between 2 sibling components, then the event bus can also be used. Check out this blog which would help you understand better.

supppose for 2 components : CompA & CompB having same parent and main.js for setting up main vue app. For passing data from CompA to CompB without involving parent component you can do the following.

in main.js file, declare a separate global Vue instance, that will be event bus.

export const bus = new Vue();

In CompA, where the event is generated : you have to emit the event to bus.

methods: {
      somethingHappened (){
          bus.$emit('changedSomething', 'new data');
      }
  }

Now the task is to listen the emitted event, so, in CompB, you can listen like.

created (){
    bus.$on('changedSomething', (newData) => {
      console.log(newData);
    })
  }

Advantages:

• Less & Clean code.
• Parent should not involve in passing down data from 1 child comp to another ( as the number of children grows, it will become hard to maintain )
• Follows pub-sub approach.

Well I did not think this was possible until I went and checked. In some previous version of Excel I could not do this. I am currently using Excel 2013.

This is what you want to do in a scatter plot:

1. right click on your data point

2. select "Format Data Labels" (note you may have to add data labels first)

3. put a check mark in "Values from Cells"
4. click on "select range" and select your range of labels you want on the points

UPDATE: Colouring Individual Labels

In order to colour the labels individually use the following steps:

1. select a label. When you first select, all labels for the series should get a box around them like the graph above.
2. Select the individual label you are interested in editing. Only the label you have selected should have a box around it like the graph below.
3. On the right hand side, as shown below, Select "TEXT OPTIONS".
4. Expand the "TEXT FILL" category if required.
5. Second from the bottom of the category list is "COLOR", select the colour you want from the pallet.

If you have the entire series selected instead of the individual label, text formatting changes should apply to all labels instead of just one.

Just remove the .val(). Like:

if ( $('html').attr('lang') == 'fr-FR' ) {
    // do this
} else {
    // do that
}

There is already the nl2br() function that inserts <br> tags before new line characters:

Example (codepad):

<?php
// Won't work
$desc = 'Line one\nline two';
// Should work
$desc2 = "Line one\nline two";

echo nl2br($desc);
echo '<br/>';
echo nl2br($desc2);
?>

But if it is still not working make sure the text $desciption is double-quoted.

That's because single quotes do not 'expand' escape sequences such as \n comparing to double quoted strings. Quote from PHP documentation:

Note: Unlike the double-quoted and heredoc syntaxes, variables and escape sequences for special characters will not be expanded when they occur in single quoted strings.

You need to specify it on the methods that can throw the exceptions. You just seperate them with a ',' if it can throw more than 1 type of exception. e.g.

public interface MyInterface {
  public MyObject find(int x) throws MyExceptionA,MyExceptionB;
}

If you do not have float exceptions enabled (which you shouldn't imho), you can simply say:

double neg_inf = -1/0.0;

This yields negative infinity. If you need a float, you can either cast the result

float neg_inf = (float)-1/0.0;

or use single precision arithmetic

float neg_inf = -1.0f/0.0f;

The result is always the same, there is exactly one representation of negative infinity in both single and double precision, and they convert to each other as you would expect.

 <div *ngFor="let item of list;trackBy: trackByFunc" >
   {{item.value}}
 </div>

In your ts file

 trackByFunc(index, item){
    return item ? item.id : undefined;
  }

Time#localtime will give you the time in the current time zone of the machine running the code:

> moment = Time.now.utc
  => 2011-03-14 15:15:58 UTC 
> moment.localtime
  => 2011-03-14 08:15:58 -0700 

Update: If you want to conver to specific time zones rather than your own timezone, you're on the right track. However, instead of worrying about EST vs EDT, just pass in the general Eastern Time zone -- it will know based on the day whether it is EDT or EST:

> Time.now.utc.in_time_zone("Eastern Time (US & Canada)")
  => Mon, 14 Mar 2011 11:21:05 EDT -04:00 
> (Time.now.utc + 10.months).in_time_zone("Eastern Time (US & Canada)")
  => Sat, 14 Jan 2012 10:21:18 EST -05:00 

You want to use the UITabBarController's selectedViewController property. All view controllers attached to a tab bar controller have a tabBarController property set, so you can, from within any of the view controllers' code:

if([[[self tabBarController] selectedViewController] isEqual:self]){
     //we're in the active controller
}else{
     //we are not
}

• .py - Regular script
• .py3 - (rarely used) Python3 script. Python3 scripts usually end with ".py" not ".py3", but I have seen that a few times

In C, there's not much difference when used in the startup function of the program (which can be main(), wmain(), _tmain() or the default name used by your compiler).

If you return in main(), control goes back to the _start() function in the C library which originally started your program, which then calls exit() anyways. So it really doesn't matter which one you use.

Had same problem, to resolve it, create a shortcut of the launcher, right click > properties > compatibility > tick on 'Override high DPI scaling behaviour' and select System Enhanced from the dropdown as shown on pic below. Relaunch eclipse after changes.

You can also just clone the repo, after cloning is done, just pick the folder or vile that you want. To clone:

git clone https://github.com/somegithubuser/somgithubrepo.git

then go to the cloned DIR and find your file or DIR you want to copy.

rtrim ($string , ","); is the easiest way.

var a = {"apples": 3, "oranges": 4, "bananas": 42};    

var array_keys = new Array();
var array_values = new Array();

for (var key in a) {
    array_keys.push(key);
    array_values.push(a[key]);
}

alert(array_keys);
alert(array_values);

There is no hostname verification in standard Java SSL sockets or indeed SSL, so that's why you can't set it at that level. Hostname verification is part of HTTPS (RFC 2818): that's why it manifests itself as javax.net.ssl.HostnameVerifier, which is applied to an HttpsURLConnection.

When you start SSMS, it allows you to choose a Server Type and Server Name. In the server type dropdown, choose "Integration Services" and connect to the server.

Then you'll be able to see what packages are in the db.

For the form, use:

<form name="form1" action="<?=$_SERVER['PHP_SELF'];?>" method="get">

and for getting the value, use the get method as follows:

$value = $_GET['name_to_send_using_get'];

If you are using JDK7 or 8, you can use try-catch with resources.This will automatically close the scanner.

try ( Scanner scanner = new Scanner(System.in); )
  {
    System.out.println("Enter the width of the Rectangle: ");
    width = scanner.nextDouble();
    System.out.println("Enter the height of the Rectangle: ");
    height = scanner.nextDouble();
  }
catch(Exception ex)
{
    //exception handling...do something (e.g., print the error message)
    ex.printStackTrace();
}

Here's an example using jquery and your html.

    $('#checkBtn').click(function() {
      checked = $("input[type=checkbox]:checked").length;

      if(!checked) {
        alert("You must check at least one checkbox.");
        return false;
      }

    });
});

</script>

For a FAB looking button this style on a MaterialButton:

<com.google.android.material.button.MaterialButton
    style="@style/Widget.MaterialComponents.ExtendedFloatingActionButton"
    app:cornerRadius="28dp"
    android:layout_width="56dp"
    android:layout_height="56dp"
    android:text="1" />

Result:

If you change the size be careful to use half of the button size as app:cornerRadius.

int random(int min, int max) //range : [min, max]
{
   static bool first = true;
   if (first) 
   {  
      srand( time(NULL) ); //seeding for the first time only!
      first = false;
   }
   return min + rand() % (( max + 1 ) - min);
}

Its simple :)

<link rel="icon" href="{{ asset('favicon.ico')}}" type="image/x-icon" />

You can create a list of lists

   public class MultiDimList: List<List<string>> {  }

or a Dictionary of key-accessible Lists

   public class MultiDimDictList: Dictionary<string, List<int>>  { }
   MultiDimDictList myDicList = new MultiDimDictList ();
   myDicList.Add("ages", new List<int>()); 
   myDicList.Add("Salaries", new List<int>()); 
   myDicList.Add("AccountIds", new List<int>()); 

Generic versions, to implement suggestion in comment from @user420667

  public class MultiDimList<T>: List<List<T>> {  }

and for the dictionary,

   public class MultiDimDictList<K, T>: Dictionary<K, List<T>>  { }

  // to use it, in client code
   var myDicList = new MultiDimDictList<string, int> ();
   myDicList.Add("ages", new List<T>()); 
   myDicList["ages"].Add(23);
   myDicList["ages"].Add(32);
   myDicList["ages"].Add(18);

   myDicList.Add("salaries", new List<T>());
   myDicList["salaries"].Add(80000);
   myDicList["salaries"].Add(100000);

   myDicList.Add("accountIds", new List<T>()); 
   myDicList["accountIds"].Add(321123);
   myDicList["accountIds"].Add(342653);

or, even better, ...

   public class MultiDimDictList<K, T>: Dictionary<K, List<T>>  
   {
       public void Add(K key, T addObject)
       {
           if(!ContainsKey(key)) Add(key, new List<T>());
           if (!base[key].Contains(addObject)) base[key].Add(addObject);
       }           
   }


  // and to use it, in client code
    var myDicList = new MultiDimDictList<string, int> ();
    myDicList.Add("ages", 23);
    myDicList.Add("ages", 32);
    myDicList.Add("ages", 18);
    myDicList.Add("salaries", 80000);
    myDicList.Add("salaries", 110000);
    myDicList.Add("accountIds", 321123);
    myDicList.Add("accountIds", 342653);

EDIT: to include an Add() method for nested instance:

public class NestedMultiDimDictList<K, K2, T>: 
           MultiDimDictList<K, MultiDimDictList<K2, T>>: 
{
       public void Add(K key, K2 key2, T addObject)
       {
           if(!ContainsKey(key)) Add(key, 
                  new MultiDimDictList<K2, T>());
           if (!base[key].Contains(key2)) 
               base[key].Add(key2, addObject);
       }    
}

You missed the * in front of NgIf (like we all have, dozens of times):

<div *ngIf="answer.accepted">&#10004;</div>

Without the *, Angular sees that the ngIf directive is being applied to the div element, but since there is no * or <template> tag, it is unable to locate a template, hence the error.

If you get this error with Angular v5:

Error: StaticInjectorError[TemplateRef]:
  StaticInjectorError[TemplateRef]:
    NullInjectorError: No provider for TemplateRef!

You may have <template>...</template> in one or more of your component templates. Change/update the tag to <ng-template>...</ng-template>.

UPDATE: This is no longer valid for newer Keras versions. Please use argmax() as in the answer from Emilia Apostolova.

The functional API models have just the predict() function which for classification would return the class probabilities. You can then select the most probable classes using the probas_to_classes() utility function. Example:

y_proba = model.predict(x)
y_classes = keras.np_utils.probas_to_classes(y_proba)

This is equivalent to model.predict_classes(x) on the Sequential model.

The reason for this is that the functional API support more general class of tasks where predict_classes() would not make sense.

add this code to your project

  public static class Extension {
        public static string TextAfter(this string value ,string search) {
            return  value.Substring(value.IndexOf(search) + search.Length);
        }
  }

then use

"code : string text ".TextAfter(":")

This is just Microsoft being cheeky. "Deprecated" implies a language feature that may not be provided in future versions of the standard language / standard libraries, as decreed by the standards committee. It does not, or should not mean, "we, unilaterally, don't think you should use it", no matter how well-founded that advice is.

You can learn some tutorials for JSP page direct access database (mysql) here

Notes:

• import sql tag library in jsp page

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

• then set datasource on page

  <sql:setDataSource var="ds" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://<yourhost>/<yourdb>" user="<user>" password="<password>"/>
  

• Now query what you want on page

  <sql:query dataSource="${ds}" var="result"> //ref  defined 'ds'
      SELECT * from <your-table>;
  </sql:query>
  

• Finally you can populate dropdowns on page using c:forEach tag to iterate result rows in select element

  <c:forEach var="row" items="${result.rows}"> //ref set var 'result' <option value='<c:out value="${row.key}"/>'><c:out value="${row.value}"/</option> </c:forEach>

answer suggested by rakesh is great but still with some discription Singleton in Android is the same as Singleton in Java: The Singleton design pattern addresses all of these concerns. With the Singleton design pattern you can:

1) Ensure that only one instance of a class is created

2) Provide a global point of access to the object

3) Allow multiple instances in the future without affecting a singleton class's clients

A basic Singleton class example:

public class MySingleton
{
    private static MySingleton _instance;

    private MySingleton()
    {

    }

    public static MySingleton getInstance()
    {
        if (_instance == null)
        {
            _instance = new MySingleton();
        }
        return _instance;
    }
}

I faced this issue too. I was using jquery.poptrox.min.js for image popping and zooming and I received an error which said:

“Uncaught TypeError: a.indexOf is not a function” error.

This is because indexOf was not supported in 3.3.1/jquery.min.js so a simple fix to this is to change it to an old version 2.1.0/jquery.min.js.

This fixed it for me.

Besides calling omp_get_num_threads() outside of the parallel region in your case, calling omp_set_num_threads() still doesn't guarantee that the OpenMP runtime will use exactly the specified number of threads. omp_set_num_threads() is used to override the value of the environment variable OMP_NUM_THREADS and they both control the upper limit of the size of the thread team that OpenMP would spawn for all parallel regions (in the case of OMP_NUM_THREADS) or for any consequent parallel region (after a call to omp_set_num_threads()). There is something called dynamic teams that could still pick smaller number of threads if the run-time system deems it more appropriate. You can disable dynamic teams by calling omp_set_dynamic(0) or by setting the environment variable OMP_DYNAMIC to false.

To enforce a given number of threads you should disable dynamic teams and specify the desired number of threads with either omp_set_num_threads():

omp_set_dynamic(0);     // Explicitly disable dynamic teams
omp_set_num_threads(4); // Use 4 threads for all consecutive parallel regions
#pragma omp parallel ...
{
    ... 4 threads used here ...
}

or with the num_threads OpenMP clause:

omp_set_dynamic(0);     // Explicitly disable dynamic teams
// Spawn 4 threads for this parallel region only
#pragma omp parallel ... num_threads(4)
{
    ... 4 threads used here ...
}

The best and the easiest ways to create a copy of a dict in both Python 2.7 and 3 are...

To create a copy of simple(single-level) dictionary:

1. Using dict() method, instead of generating a reference that points to the existing dict.

my_dict1 = dict()
my_dict1["message"] = "Hello Python"
print(my_dict1)  # {'message':'Hello Python'}

my_dict2 = dict(my_dict1)
print(my_dict2)  # {'message':'Hello Python'}

# Made changes in my_dict1 
my_dict1["name"] = "Emrit"
print(my_dict1)  # {'message':'Hello Python', 'name' : 'Emrit'}
print(my_dict2)  # {'message':'Hello Python'}

2. Using the built-in update() method of python dictionary.

my_dict2 = dict()
my_dict2.update(my_dict1)
print(my_dict2)  # {'message':'Hello Python'}

# Made changes in my_dict1 
my_dict1["name"] = "Emrit"
print(my_dict1)  # {'message':'Hello Python', 'name' : 'Emrit'}
print(my_dict2)  # {'message':'Hello Python'}

To create a copy of nested or complex dictionary:

Use the built-in copy module, which provides a generic shallow and deep copy operations. This module is present in both Python 2.7 and 3.*

import copy

my_dict2 = copy.deepcopy(my_dict1)

SELECT q'[Alex's Tea Factory]' FROM DUAL

Try this:

CREATE FUNCTION dbo.FnDAYSADDNOWK(
          @addDate AS DATE, 
          @numDays AS INT
       ) RETURNS DATETIME AS

    BEGIN
    WHILE @numDays > 0 BEGIN
        SET @addDate = DATEADD(day, 1, @addDate)    
        IF DATENAME(DW, @addDate) <> 'sunday' BEGIN
            SET @numDays = @numDays - 1 
        END
    END

    RETURN CAST(@addDate AS DATETIME)
END

This might work for you (GNU sed):

sed -si '/#include/{s//& "newfile.h\n&/;:a;$!{n;ba}}' file1 file2 file....

or if memory is not a problem:

sed -si ':a;$!{N;ba};s/#include/& "newfile.h\n&/' file1 file2 file...

Try this code.You can replace any character with another given character. Here I tried to replace the letter 'a' with "-" character for the give string "abcdeaa"

OutPut -->_bcdef__

    public class Replace {

    public static void replaceChar(String str,String target){
        String result = str.replaceAll(target, "_");
        System.out.println(result);
    }

    public static void main(String[] args) {
        replaceChar("abcdefaa","a");
    }

}

The solution in a more elegant way.

var myData=['237','124','255','124','366','255'];

console.log(Array.from(new Set(myData)).sort());

I know the question is very old, but maybe someone will come in handy

When the above solution doesn’t work try this:

<IfModule mod_security.c>
  SecRuleEngine Off
  SecFilterInheritance Off
  SecFilterEngine Off
  SecFilterScanPOST Off
  SecRuleRemoveById 300015 3000016 3000017
</IfModule>

Basically I was trying to get my code to have a middle section on a 'row' to auto-adjust to the content on both sides (in my case, a dotted line separator). Like @Michael_B suggested, the key is using display:flex on the row container and at least making sure your middle container on the row has a flex-grow value of at least 1 higher than the outer containers (if outer containers don't have any flex-grow properties applied, middle container only needs 1 for flex-grow).

Here's a pic of what I was trying to do and sample code for how I solved it.

.row {
  background: lightgray;
  height: 30px;
  width: 100%;
  display: flex;
  align-items:flex-end;
  margin-top:5px;
}
.left {
  background:lightblue;
}
.separator{
  flex-grow:1;
  border-bottom:dotted 2px black;
}
.right {
  background:coral;
}

<div class="row">
  <div class="left">Left</div>
  <div class="separator"></div>
  <div class="right">Right With Text</div>
</div>
<div class="row">
  <div class="left">Left With More Text</div>
  <div class="separator"></div>
  <div class="right">Right</div>
</div>
<div class="row">
  <div class="left">Left With Text</div>
  <div class="separator"></div>
  <div class="right">Right With More Text</div>
</div>

you can use

console.clear();

if you are working with javascript coding.

else you can use CTR+L to clear cosole editor.

foreach(preg_split('~[\r\n]+~', $text) as $line){
    if(empty($line) or ctype_space($line)) continue; // skip only spaces
    // if(!strlen($line = trim($line))) continue; // or trim by force and skip empty
    // $line is trimmed and nice here so use it
}

^ this is how you break lines properly, cross-platform compatible with Regexp :)

I looked into this a bit more and the actual problem seems to be with assigning initial to page width under the print media rule. It seems like in Chrome width: initial on the .page element results in scaling of the page content if no specific length value is defined for width on any of the parent elements (width: initial in this case resolves to width: auto ... but actually any value smaller than the size defined under the @page rule causes the same issue).

So not only the content is now too long for the page (by about 2cm), but also the page padding will be slightly more than the initial 2cm and so on (it seems to render the contents under width: auto to the width of ~196mm and then scale the whole content up to the width of 210mm ~ but strangely exactly the same scaling factor is applied to contents with any width smaller than 210mm).

To fix this problem you can simply in the print media rule assign the A4 paper width and hight to html, body or directly to .page and in this case avoid the initial keyword.

DEMO

@page {
  size: A4;
  margin: 0;
}
@media print {
  html, body {
    width: 210mm;
    height: 297mm;
  }
  /* ... the rest of the rules ... */
}

^{This seems to keep everything else the way it is in your original CSS and fix the problem in Chrome (tested in different versions of Chrome under Windows, OS X and Ubuntu).}

JSONP is a simple way to overcome browser restrictions when sending JSON responses from different domains from the client.

But the practical implementation of the approach involves subtle differences that are often not explained clearly.

Here is a simple tutorial that shows JSON and JSONP side by side.

All the code is freely available at Github and a live version can be found at http://json-jsonp-tutorial.craic.com

UPDATE: Somebody just won't take no as the answer, and I like it, very much, especially to this particular question.

GOOD NEWS, There is a way now --

The solution is Rocker: https://github.com/grammarly/rocker

John Yani said, "IMO, it solves all the weak points of Dockerfile, making it suitable for development."

Rocker

https://github.com/grammarly/rocker

By introducing new commands, Rocker aims to solve the following use cases, which are painful with plain Docker:

1. Mount reusable volumes on build stage, so dependency management tools may use cache between builds.
2. Share ssh keys with build (for pulling private repos, etc.), while not leaving them in the resulting image.
3. Build and run application in different images, be able to easily pass an artifact from one image to another, ideally have this logic in a single Dockerfile.
4. Tag/Push images right from Dockerfiles.
5. Pass variables from shell build command so they can be substituted to a Dockerfile.

And more. These are the most critical issues that were blocking our adoption of Docker at Grammarly.

Update: Rocker has been discontinued, per the official project repo on Github

As of early 2018, the container ecosystem is much more mature than it was three years ago when this project was initiated. Now, some of the critical and outstanding features of rocker can be easily covered by docker build or other well-supported tools, though some features do remain unique to rocker. See https://github.com/grammarly/rocker/issues/199 for more details.

There is no best way, it depends on your use case.

• Use way 1 if you want to create several similar objects. In your example, Person (you should start the name with a capital letter) is called the constructor function. This is similar to classes in other OO languages.
• Use way 2 if you only need one object of a kind (like a singleton). If you want this object to inherit from another one, then you have to use a constructor function though.
• Use way 3 if you want to initialize properties of the object depending on other properties of it or if you have dynamic property names.

Update: As requested examples for the third way.

Dependent properties:

The following does not work as this does not refer to book. There is no way to initialize a property with values of other properties in a object literal:

var book = {
    price: somePrice * discount,
    pages: 500,
    pricePerPage: this.price / this.pages
};

instead, you could do:

var book = {
    price: somePrice * discount,
    pages: 500
};
book.pricePerPage = book.price / book.pages;
// or book['pricePerPage'] = book.price / book.pages;

Dynamic property names:

If the property name is stored in some variable or created through some expression, then you have to use bracket notation:

var name = 'propertyName';

// the property will be `name`, not `propertyName`
var obj = {
    name: 42
}; 

// same here
obj.name = 42;

// this works, it will set `propertyName`
obj[name] = 42;

When you pass a string to the filter function, the string is interpreted as SQL. Count is a SQL keyword and using count as a variable confuses the parser. This is a small bug (you can file a JIRA ticket if you want to).

You can easily avoid this by using a column expression instead of a String:

df.groupBy("x").count()
  .filter($"count" >= 2)
  .show()

.htaccess Solution

To brute force all CSV files on your server to download, add in your .htaccess file:

AddType application/octet-stream csv

PHP Solution

header('Content-Type: application/csv');
header('Content-Disposition: attachment; filename=example.csv');
header('Pragma: no-cache');
readfile("/path/to/yourfile.csv");

After doing some research, it seems that this problem may be due to a google bug. For me, I was able to leave this line in my Activities onCreate method:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

AND I changed my targetSdkVersion to 26. Having that line in my onCreate still resulted in a crash while my targetSdkVersion was still set at 27. Since no one else's solution has worked for me thus far, I found that this works as a temporary fix for now.

self::staticMethod();

More information about the Static keyword.

In PostgreSQL this is typically simpler and faster (more performance optimization below):

SELECT DISTINCT ON (customer)
       id, customer, total
FROM   purchases
ORDER  BY customer, total DESC, id;

Or shorter (if not as clear) with ordinal numbers of output columns:

SELECT DISTINCT ON (2)
       id, customer, total
FROM   purchases
ORDER  BY 2, 3 DESC, 1;

If total can be NULL (won't hurt either way, but you'll want to match existing indexes):

...
ORDER  BY customer, total DESC NULLS LAST, id;

Major points

DISTINCT ON is a PostgreSQL extension of the standard (where only DISTINCT on the whole SELECT list is defined).

List any number of expressions in the DISTINCT ON clause, the combined row value defines duplicates. The manual:

Obviously, two rows are considered distinct if they differ in at least one column value. Null values are considered equal in this comparison.

Bold emphasis mine.

DISTINCT ON can be combined with ORDER BY. Leading expressions in ORDER BY must be in the set of expressions in DISTINCT ON, but you can rearrange order among those freely. Example.
You can add additional expressions to ORDER BY to pick a particular row from each group of peers. Or, as the manual puts it:

The DISTINCT ON expression(s) must match the leftmost ORDER BY expression(s). The ORDER BY clause will normally contain additional expression(s) that determine the desired precedence of rows within each DISTINCT ON group.

I added id as last item to break ties:
"Pick the row with the smallest id from each group sharing the highest total."

To order results in a way that disagrees with the sort order determining the first per group, you can nest above query in an outer query with another ORDER BY. Example.

If total can be NULL, you most probably want the row with the greatest non-null value. Add NULLS LAST like demonstrated. See:

• Sort by column ASC, but NULL values first?

The SELECT list is not constrained by expressions in DISTINCT ON or ORDER BY in any way. (Not needed in the simple case above):

• You don't have to include any of the expressions in DISTINCT ON or ORDER BY.

• You can include any other expression in the SELECT list. This is instrumental for replacing much more complex queries with subqueries and aggregate / window functions.

I tested with Postgres versions 8.3 – 13. But the feature has been there at least since version 7.1, so basically always.

Index

The perfect index for the above query would be a multi-column index spanning all three columns in matching sequence and with matching sort order:

CREATE INDEX purchases_3c_idx ON purchases (customer, total DESC, id);

May be too specialized. But use it if read performance for the particular query is crucial. If you have DESC NULLS LAST in the query, use the same in the index so that sort order matches and the index is applicable.

Effectiveness / Performance optimization

Weigh cost and benefit before creating tailored indexes for each query. The potential of above index largely depends on data distribution.

The index is used because it delivers pre-sorted data. In Postgres 9.2 or later the query can also benefit from an index only scan if the index is smaller than the underlying table. The index has to be scanned in its entirety, though.

For few rows per customer (high cardinality in column customer), this is very efficient. Even more so if you need sorted output anyway. The benefit shrinks with a growing number of rows per customer.
Ideally, you have enough work_mem to process the involved sort step in RAM and not spill to disk. But generally setting work_mem too high can have adverse effects. Consider SET LOCAL for exceptionally big queries. Find how much you need with EXPLAIN ANALYZE. Mention of "Disk:" in the sort step indicates the need for more:

• Configuration parameter work_mem in PostgreSQL on Linux
• Optimize simple query using ORDER BY date and text

For many rows per customer (low cardinality in column customer), a loose index scan (a.k.a. "skip scan") would be (much) more efficient, but that's not implemented up to Postgres 13. (An implementation for index-only scans is in development for Postgres 14. See here and here.)
For now, there are faster query techniques to substitute for this. In particular if you have a separate table holding unique customers, which is the typical use case. But also if you don't:

• Optimize GROUP BY query to retrieve latest row per user
• Optimize groupwise maximum query
• Query last N related rows per row

Benchmark

I had a simple benchmark here which is outdated by now. I replaced it with a detailed benchmark in this separate answer.

It has to be a constant - the value has to be computable at the time that the procedure is created, and that one computation has to provide the value that will always be used.

Look at the definition of sys.all_parameters:

default_value sql_variant If has_default_value is 1, the value of this column is the value of the default for the parameter; otherwise, NULL.

That is, whatever the default for a parameter is, it has to fit in that column.

As Alex K pointed out in the comments, you can just do:

CREATE PROCEDURE [dbo].[problemParam] 
    @StartDate INT = NULL,
    @EndDate INT = NULL
AS  
BEGIN
   SET @StartDate = COALESCE(@StartDate,CONVERT(INT,(CONVERT(CHAR(8),GETDATE()-130,112))))

provided that NULL isn't intended to be a valid value for @StartDate.

As to the blog post you linked to in the comments - that's talking about a very specific context - that, the result of evaluating GETDATE() within the context of a single query is often considered to be constant. I don't know of many people (unlike the blog author) who would consider a separate expression inside a UDF to be part of the same query as the query that calls the UDF.

The best that I've been able to do is

$(this).closest('.modal').modal('toggle');

This gets the modal holding the DOM object you triggered the event on (guessing you're clicking a button). Gets the closest parent '.modal' and toggles it. Obviously only works because it's inside the modal you clicked.

You can however do this:

$(".modal:visible").modal('toggle');

This gets the modal that is displaying (since you can only have one open at a time), and triggers the 'toggle' This would not work without ":visible"

I have discovered that you cannot have conditionals outside of the stored procedure in mysql. This is why the syntax error. As soon as I put the code that I needed between

   BEGIN
   SELECT MONTH(CURDATE()) INTO @curmonth;
   SELECT MONTHNAME(CURDATE()) INTO @curmonthname;
   SELECT DAY(LAST_DAY(CURDATE())) INTO @totaldays;
   SELECT FIRST_DAY(CURDATE()) INTO @checkweekday;
   SELECT DAY(@checkweekday) INTO @checkday;
   SET @daycount = 0;
   SET @workdays = 0;

     WHILE(@daycount < @totaldays) DO
       IF (WEEKDAY(@checkweekday) < 5) THEN
         SET @workdays = @workdays+1;
       END IF;
       SET @daycount = @daycount+1;
       SELECT ADDDATE(@checkweekday, INTERVAL 1 DAY) INTO @checkweekday;
     END WHILE;
   END

Just for others:

If you are not sure how to create a routine in phpmyadmin you can put this in the SQL query

    delimiter ;;
    drop procedure if exists test2;;
    create procedure test2()
    begin
    select ‘Hello World’;
    end
    ;;

Run the query. This will create a stored procedure or stored routine named test2. Now go to the routines tab and edit the stored procedure to be what you want. I also suggest reading http://net.tutsplus.com/tutorials/an-introduction-to-stored-procedures/ if you are beginning with stored procedures.

The first_day function you need is: How to get first day of every corresponding month in mysql?

Showing the Procedure is working Simply add the following line below END WHILE and above END

    SELECT @curmonth,@curmonthname,@totaldays,@daycount,@workdays,@checkweekday,@checkday;

Then use the following code in the SQL Query Window.

    call test2 /* or whatever you changed the name of the stored procedure to */

NOTE: If you use this please keep in mind that this code does not take in to account nationally observed holidays (or any holidays for that matter).

Poor man's configuration file:

Add to your index.html as first líne in the body tag:

<script lang="javascript" src="assets/config.js"></script>

Add assets/config.js:

var config = {
    apiBaseUrl: "http://localhost:8080"
}

Add config.ts:

export const config: AppConfig = window['config']

export interface AppConfig {
    apiBaseUrl: string
}

This is an old post however, one alternative is to use the command options:

ftp -n -s:ftpcmd.txt

the -n will suppress the initial login and then the file contents would be: (replace the 127.0.0.1 with your FTP site url)

open 127.0.0.1
user myFTPuser myftppassword
other commands here...

This avoids the user/password on separate lines

Quick answer: the FROM address must exactly match the account you are sending from, or you will get a error 5.7.1 Client does not have permissions to send as this sender.

My guess is that prevents email spoofing with your Office 365 account, otherwise you might be able to send as [email protected].

Another thing to try is in the authentication, fill in the third field with the domain, like

Dim smtpAuth = New System.Net.NetworkCredential(
    "TheDude", "hunter2password", "MicrosoftOffice365Domain.com")

If that doesn't work, double check that you can log into the account at: https://portal.microsoftonline.com

Yet another thing to note is your Antivirus solution may be blocking programmatic access to ports 25 and 587 as a anti-spamming solution. Norton and McAfee may silently block access to these ports. Only enabling Mail and Socket debugging will allow you to notice it (see below).

One last thing to note, the Send method is Asynchronous. If you call

Dispose

Detailed Answer: With Visual Studio (VB.NET or C# doesn't matter), I made a simple form with a button that created the Mail Message, similar to that above. Then I added this to the application.exe.config (in the bin/debug directory of my project). This enables the Output tab to have detailed debug info.

1. Click on Window > Show view > Server or right click on the server in "Servers" view, select "Properties".
2. In the "General" panel, click on the "Switch Location" button.
3. The "Location: [workspace metadata]" should replace by something else.
4. Open the Overview screen for the server by double clicking it.
5. In the Server locations tab , select "Use Tomcat location".
6. Save the configurations and restart the Server.

You may want to follow the steps above before starting the server. Because server location section goes grayed-unreachable.

It looks like you just hard-coded the row and column; otherwise, a couple of small tweaks, and I think you're there:

1. Iterate over the ResultSet
2. Create a new Object for each row, to store the fields you need
3. Add this new object to ArrayList or Hashmap or whatever you fancy
4. Close the ResultSet, Statement and the DB connection

Done

EDIT: now that you have posted code, I have made a few changes to it.

public List resultSetToArrayList(ResultSet rs) throws SQLException{
  ResultSetMetaData md = rs.getMetaData();
  int columns = md.getColumnCount();
  ArrayList list = new ArrayList(50);
  while (rs.next()){
     HashMap row = new HashMap(columns);
     for(int i=1; i<=columns; ++i){           
      row.put(md.getColumnName(i),rs.getObject(i));
     }
      list.add(row);
  }

 return list;
}

For me, ctrl + m is used to save the webpage as png, so it does not work properly. But I find another way.

On the toolbar, there is a bottom named open the command paletee, you can click it and type in the line, and you can see the toggle cell line number here.

To execute a method you need to add parentheses, even if the method does not take arguments.

So it should be:

string t = obj.getTitle();

I recommend @Jens Gustedt hexadecimal solution: use %a.

OP wants “print with maximum precision (or at least to the most significant decimal)”.

A simple example would be to print one seventh as in:

#include <float.h>
int Digs = DECIMAL_DIG;
double OneSeventh = 1.0/7.0;
printf("%.*e\n", Digs, OneSeventh);
// 1.428571428571428492127e-01

But let's dig deeper ...

Mathematically, the answer is "0.142857 142857 142857 ...", but we are using finite precision floating point numbers. Let's assume IEEE 754 double-precision binary. So the OneSeventh = 1.0/7.0 results in the value below. Also shown are the preceding and following representable double floating point numbers.

OneSeventh before = 0.1428571428571428 214571170656199683435261249542236328125
OneSeventh        = 0.1428571428571428 49212692681248881854116916656494140625
OneSeventh after  = 0.1428571428571428 769682682968777953647077083587646484375

Printing the exact decimal representation of a double has limited uses.

C has 2 families of macros in <float.h> to help us.
The first set is the number of significant digits to print in a string in decimal so when scanning the string back, we get the original floating point. There are shown with the C spec's minimum value and a sample C11 compiler.

FLT_DECIMAL_DIG   6,  9 (float)                           (C11)
DBL_DECIMAL_DIG  10, 17 (double)                          (C11)
LDBL_DECIMAL_DIG 10, 21 (long double)                     (C11)
DECIMAL_DIG      10, 21 (widest supported floating type)  (C99)

The second set is the number of significant digits a string may be scanned into a floating point and then the FP printed, still retaining the same string presentation. There are shown with the C spec's minimum value and a sample C11 compiler. I believe available pre-C99.

FLT_DIG   6, 6 (float)
DBL_DIG  10, 15 (double)
LDBL_DIG 10, 18 (long double)

The first set of macros seems to meet OP's goal of significant digits. But that macro is not always available.

#ifdef DBL_DECIMAL_DIG
  #define OP_DBL_Digs (DBL_DECIMAL_DIG)
#else  
  #ifdef DECIMAL_DIG
    #define OP_DBL_Digs (DECIMAL_DIG)
  #else  
    #define OP_DBL_Digs (DBL_DIG + 3)
  #endif
#endif

The "+ 3" was the crux of my previous answer. Its centered on if knowing the round-trip conversion string-FP-string (set #2 macros available C89), how would one determine the digits for FP-string-FP (set #1 macros available post C89)? In general, add 3 was the result.

Now how many significant digits to print is known and driven via <float.h>.

To print N significant decimal digits one may use various formats.

With "%e", the precision field is the number of digits after the lead digit and decimal point. So - 1 is in order. Note: This -1 is not in the initial int Digs = DECIMAL_DIG;

printf("%.*e\n", OP_DBL_Digs - 1, OneSeventh);
// 1.4285714285714285e-01

With "%f", the precision field is the number of digits after the decimal point. For a number like OneSeventh/1000000.0, one would need OP_DBL_Digs + 6 to see all the significant digits.

printf("%.*f\n", OP_DBL_Digs    , OneSeventh);
// 0.14285714285714285
printf("%.*f\n", OP_DBL_Digs + 6, OneSeventh/1000000.0);
// 0.00000014285714285714285

Note: Many are use to "%f". That displays 6 digits after the decimal point; 6 is the display default, not the precision of the number.

If you don't want to go down the VBA path, there is this trick from a previous question.

Excel 2010: how to use autocomplete in validation list

It does add some annoying bulk to the top of your sheets, and potential maintenance (should you need more options, adding names of people from a staff list, new projects etc.) but works all the same.

Yes, you can definitely do this. Just use something like

.parent:hover .child {
   /* ... */
}

According to this page it's supported by all major browsers.

EntityManager interface is similar to sessionFactory in hibernate. EntityManager under javax.persistance package but session and sessionFactory under org.hibernate.Session/sessionFactory package.

Entity manager is JPA specific and session/sessionFactory are hibernate specific.

Because it's an object, the way to assign value to its properties is using :.

Change the = to : to fix the error.

var options = {
  host: 'localhost',
  port: 8080,
  path: '/',
  method: 'POST'
 }

Sometimes we need a code block where we need to perform some operation right after setState where we are sure the state is being updated. That is where setState callback comes into play

For example, there was a scenario where I needed to enable a modal for 2 customers out of 20 customers, for the customers where we enabled it, there was a set of time taking API calls, so it looked like this

async componentDidMount() {
  const appConfig = getCustomerConfig();
  this.setState({enableModal: appConfig?.enableFeatures?.paymentModal }, async 
   ()=>{
     if(this.state.enableModal){
       //make some API call for data needed in poput
     }
  });
}

enableModal boolean was required in UI blocks in the render function as well, that's why I did setState here, otherwise, could've just checked condition once and either called API set or not.

The fact that the sort values in the OP are integers isn't relevant to the question per se. In other words, the accepted answer would work if the sort value was text. I bring this up to also point out that the sort can be modified during the sort (for example, to account for upper and lower case).

>>> sorted([(121, 'abc'), (231, 'def'), (148, 'ABC'), (221, 'DEF')], key=lambda x: x[1])
[(148, 'ABC'), (221, 'DEF'), (121, 'abc'), (231, 'def')]
>>> sorted([(121, 'abc'), (231, 'def'), (148, 'ABC'), (221, 'DEF')], key=lambda x: str.lower(x[1]))
[(121, 'abc'), (148, 'ABC'), (231, 'def'), (221, 'DEF')]

Try this:

<?php
//This function prints a text array as an html list.
function alist ($array) {  
  $alist = "<ul>";
  for ($i = 0; $i < sizeof($array); $i++) {
    $alist .= "<li>$array[$i]";
  }
  $alist .= "</ul>";
  return $alist;
}
//Try to get ImageMagick "convert" program version number.
exec("convert -version", $out, $rcode);
//Print the return code: 0 if OK, nonzero if error. 
echo "Version return code is $rcode <br>"; 
//Print the output of "convert -version"    
echo alist($out); 
?>

Expanding on Abdul's answer, you can obtain a KeyedTuple instead of a discrete collection of rows by joining the columns:

q = Session.query(*User.__table__.columns + Document.__table__.columns).\
        select_from(User).\
        join(Document, User.email == Document.author).\
        filter(User.email == 'someemail').all()

• Your formatting pattern fails to match the input string, as noted by other Answers.
• Your input format is terrible.
• You are using troublesome old date-time classes that were supplanted years ago by the java.time classes.

ISO 8601

Instead a format such as yours, use ISO 8601 standard formats for exchanging date-time values as text.

The java.time classes use the standard ISO 8601 formats by default when parsing/generating strings.

Proper time zone name

Specify a proper time zone name in the format of continent/region, such as America/Montreal, Africa/Casablanca, or Pacific/Auckland. Never use the 3-4 letter abbreviation such as EST or IST as they are not true time zones, not standardized, and not even unique(!).

Your IST could mean Iceland Standard Time, India Standard Time, Ireland Standard Time, or others. The java.time classes are left to merely guessing, as there is no logical solution to this ambiguity.

java.time

The modern approach uses the java.time classes.

Define a formatting pattern to match your input strings.

String input = "Sat Jun 01 12:53:10 IST 2013";
DateTimeFormatter f = DateTimeFormatter.ofPattern( "EEE MMM dd HH:mm:ss z uuuu" , Locale.US );
ZonedDateTime zdt = ZonedDateTime.parse( input , f );

zdt.toString(): 2013-06-01T12:53:10Z[Atlantic/Reykjavik]

If your input was not intended for Iceland, you should pre-parse the string to adjust to a proper time zone name. For example, if you are certain the input was intended for India, change IST to Asia/Kolkata.

String input = "Sat Jun 01 12:53:10 IST 2013".replace( "IST" , "Asia/Kolkata" );
DateTimeFormatter f = DateTimeFormatter.ofPattern( "EEE MMM dd HH:mm:ss z uuuu" , Locale.US );
ZonedDateTime zdt = ZonedDateTime.parse( input , f );

zdt.toString(): 2013-06-01T12:53:10+05:30[Asia/Kolkata]

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Just small change need in test.ts file inside src folder:

const context = require.context('./', true, /test-example\.spec\.ts$/);

Here, test-example is the exact file name which we need to run

In the same way, if you need to test the service file only you can replace the filename like "/test-example.service"

struct A {};
struct B : A {};
struct C {}; 

int main()
{
    A* a = new A;    

    int i = 10;

    a = (A*) (&i); // NO ERROR! FAIL!

    //a = static_cast<A*>(&i); ERROR! SMART!

    A* b = new B;

    B* b2 = static_cast<B*>(b); // NO ERROR! SMART!

    C* c = (C*)(b); // NO ERROR! FAIL!

    //C* c = static_cast<C*>(b); ERROR! SMART!
}

if( isset( $_POST['login'] ) &&  strlen( $_POST['login'] ))
{
  // valid $_POST['login'] is set and its value is greater than zero
}
else
{
  //error either $_POST['login'] is not set or $_POST['login'] is empty form field
}

Posting this because unlike the previous answers this one is generic, no external libraries, O(n), actually filters out the duplicate and keeps the order the OP is asking for (by placing the last matching element in place of first appearance):

function unique(array, keyfunc) {
    return array.reduce((result, entry) => {
        const key = keyfunc(entry)
        if(key in result.seen) {
            result.array[result.seen[key]] = entry
        } else {
            result.seen[key] = result.array.length
            result.array.push(entry)
        }
        return result
    }, { array: [], seen: {}}).array
}

Usage:

var arr1 = new Array({name: "lang", value: "English"}, {name: "age", value: "18"})
var arr2 = new Array({name : "childs", value: '5'}, {name: "lang", value: "German"})

var arr3 = unique([...arr1, ...arr2], x => x.name)
/* arr3 == [ 
    {name: "lang", value: "German"}, 
    {name: "age", value: "18"},
    {name: "childs", value: "5"}
]*/

pushing a value (not necessarily stored in a register) means writing it to the stack.

popping means restoring whatever is on top of the stack into a register. Those are basic instructions:

push 0xdeadbeef      ; push a value to the stack
pop eax              ; eax is now 0xdeadbeef

; swap contents of registers
push eax
mov eax, ebx
pop ebx

I have just discovered and used FETCH_HEAD. I wanted a local copy of some software from a server and I did

git fetch gitserver release_1

gitserver is the name of my machine that stores git repositories. release_1 is a tag for a version of the software. To my surprise, release_1 was then nowhere to be found on my local machine. I had to type

 git tag release_1 FETCH_HEAD 

to complete the copy of the tagged chain of commits (release_1) from the remote repository to the local one. Fetch had found the remote tag, copied the commit to my local machine, had not created a local tag, but had set FETCH_HEAD to the value of the commit, so that I could find and use it. I then used FETCH_HEAD to create a local tag which matched the tag on the remote. That is a practical illustration of what FETCH_HEAD is and how it can be used, and might be useful to someone else wondering why git fetch doesn't do what you would naively expect.

In my opinion it is best avoided for that purpose and a better way to achieve what I was trying to do is

git fetch gitserver release_1:release_1

i.e. to fetch release_1 and call it release_1 locally. (It is source:dest, see https://git-scm.com/book/en/v2/Git-Internals-The-Refspec; just in case you'd like to give it a different name!)

You might want to use FETCH_HEAD at times though:-

git fetch gitserver bugfix1234
git cherry-pick FETCH_HEAD

might be a nice way of using bug fix number 1234 from your Git server, and leaving Git's garbage collection to dispose of the copy from the server once the fix has been cherry-picked onto your current branch. (I am assuming that there is a nice clean tagged commit containing the whole of the bug fix on the server!)

• "Final" denotes that something cannot be changed. You usually want to use this on static variables that will hold the same value throughout the life of your program.
• "Finally" is used in conjunction with a try/catch block. Anything inside of the "finally" clause will be executed regardless of if the code in the 'try' block throws an exception or not.
• "Finalize" is called by the JVM before an object is about to be garbage collected.

You can filter all characters from the string that are not printable using string.printable, like this:

>>> s = "some\x00string. with\x15 funny characters"
>>> import string
>>> printable = set(string.printable)
>>> filter(lambda x: x in printable, s)
'somestring. with funny characters'

string.printable on my machine contains:

0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
!"#$%&\'()*+,-./:;<=>?@[\\]^_`{|}~ \t\n\r\x0b\x0c

EDIT: On Python 3, filter will return an iterable. The correct way to obtain a string back would be:

''.join(filter(lambda x: x in printable, s))

You can get the coordinate of the target element and set the scroll position to it. But this is so complicated.

Here is a lazier way to do that:

function jump(h){
    var url = location.href;               //Save down the URL without hash.
    location.href = "#"+h;                 //Go to the target element.
    history.replaceState(null,null,url);   //Don't like hashes. Changing it back.
}

This uses replaceState to manipulate the url. If you also want support for IE, then you will have to do it the complicated way:

function jump(h){
    var top = document.getElementById(h).offsetTop; //Getting Y of target element
    window.scrollTo(0, top);                        //Go there directly or some transition
}?

Demo: http://jsfiddle.net/DerekL/rEpPA/
Another one w/ transition: http://jsfiddle.net/DerekL/x3edvp4t/

You can also use .scrollIntoView:

document.getElementById(h).scrollIntoView();   //Even IE6 supports this

_{(Well I lied. It's not complicated at all.)}

Solved it by setting workspace on a local folder, and set data from import project, from existing resources.

String s = "1";

try {
   long l = Long.parseLong(s);       
} catch (NumberFormatException e) {
   System.out.println("NumberFormatException: " + e.getMessage());
}

I think you must firstly add a .wav file to Resources. For example you have sound file named Sound.wav. After you added the Sound.wav file to Resources, you can use this code:

System.Media.SoundPlayer player = new System.Media.SoundPlayer(Properties.Resources.Sound);
player.Play();

This is another way to play sound.

You need to have better understanding of the python language and its standard library to translate the expression

cat "$filename": Reads the file cat "$filename" and dumps the content to stdout

|: pipe redirects the stdout from previous command and feeds it to the stdin of the next command

grep "something": Searches the regular expressionsomething plain text data file (if specified) or in the stdin and returns the matching lines.

cut -d'"' -f2: Splits the string with the specific delimiter and indexes/splices particular fields from the resultant list

Python Equivalent

cat "$filename"  | with open("$filename",'r') as fin:        | Read the file Sequentially
                 |     for line in fin:                      |   
-----------------------------------------------------------------------------------
grep 'something' | import re                                 | The python version returns
                 | line = re.findall(r'something', line)[0]  | a list of matches. We are only
                 |                                           | interested in the zero group
-----------------------------------------------------------------------------------
cut -d'"' -f2    | line = line.split('"')[1]                 | Splits the string and selects
                 |                                           | the second field (which is
                 |                                           | index 1 in python)

Combining

import re
with open("filename") as origin_file:
    for line in origin_file:
        line = re.findall(r'something', line)
        if line:
           line = line[0].split('"')[1]
        print line

Think that JavaScriptDevelopmentTools might do it. Although, I have eclipse indigo, and I'm pretty sure it does that kind of thing automatically.

Looks like you don't have the development libraries installed. Install them using:

sudo apt-get install libqt4-dev

As you said int the comments that you have them installed, just re-install it. Now. to update the locate's database, issue this command $sudo updatedb

Then $locate QApplication to check that you now have the header file installed.

Now, goto the the folder where you have the code & type these commands

qmake -project
qmake
make

Then you can find the binary created.

Alternatively, you can use Qt Creator if you want the GUI.

I was experiencing the same problem on OS X. I've solved it now. I post my solution here for anyone who has the similar issue.

Firstly, I set the password for root in mysql client:

shell> mysql -u root
mysql> FLUSH PRIVILEGES;
mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('MY_PASSWORD');

Then, I checked the version info:

shell> /usr/local/mysql/bin/mysqladmin -u root -p version
...
Server version    5.6.26
Protocol version  10
Connection        Localhost via UNIX socket
UNIX socket       /tmp/mysql.sock
Uptime:           11 min 0 sec
...

Finally, I changed the connect_type parameter from tcp to socket and added the parameter socket in config.inc.php:

$cfg['Servers'][$i]['host'] = 'localhost';
$cfg['Servers'][$i]['connect_type'] = 'socket';
$cfg['Servers'][$i]['socket'] = '/tmp/mysql.sock';

Use my example...

 public void createNotification() {
        NotificationManager notificationManager = (NotificationManager) 
              getSystemService(NOTIFICATION_SERVICE);
        Notification notification = new Notification(R.drawable.icon,
            "message", System.currentTimeMillis());
        // Hide the notification after its selected
        notification.flags |= Notification.FLAG_AUTO_CANCEL;
        Vibrator vibrator = (Vibrator)getSystemService(Context.VIBRATOR_SERVICE);
        long[] pattern = { 0, 100, 600, 100, 700};
        vibrator.vibrate(pattern, -1);
     Intent intent = new Intent(this, Main.class);
     PendingIntent activity = PendingIntent.getActivity(this, 0, intent, 0);
     String sms = getSharedPreferences("SMSPREF", MODE_PRIVATE).getString("incoming", "EMPTY");
        notification.setLatestEventInfo(this, "message" ,
            sms, activity);
        notification.number += 1;
        notificationManager.notify(0, notification);

      }

@laryx-decidua: I think you are only seeing the 18.x instant client releases that are in the ol7_oci_included repo. The 19.x instant client RPMs, at the moment, are only in the ol7_oracle_instantclient repo. Easiest way to access that repo is:

yum install oracle-release-el7

For WAMP 3.0 : Click Structure Below Add 1 Column you will see '- Indexes' Click -Indexes and drop whichever index you want.

I had a similar error while I was creating a custom modal.

const CustomModal = (visible, modalText, modalHeader) => {}

Problem was that I didn't wrap my values to curly brackets like this.

const CustomModal = ({visible, modalText, modalHeader}) => {}

If you have multiple values to pass to the component, you should use curly brackets around it.

The JLabel background is transparent by default. Set the opacity at true like that:

label.setOpaque(true);

Have you tried running npm config list? And, if you want to see the defaults, run npm config ls -l.

I listened to that podcast, and it was amusing, but the security argument made no sense to me. If you've compromised server A, and that server can access data on server B, then you instantly have access to the data on server B.

The tags include 'sendmail' so here's a solution using that:

(
echo "From: [email protected] "
echo "To: [email protected] "
echo "MIME-Version: 1.0"
echo "Content-Type: multipart/alternative; " 
echo ' boundary="some.unique.value.ABC123/server.xyz.com"' 
echo "Subject: Test HTML e-mail." 
echo "" 
echo "This is a MIME-encapsulated message" 
echo "" 
echo "--some.unique.value.ABC123/server.xyz.com" 
echo "Content-Type: text/html" 
echo "" 
echo "<html> 
<head>
<title>HTML E-mail</title>
</head>
<body>
<a href='http://www.google.com'>Click Here</a>
</body>
</html>"
echo "------some.unique.value.ABC123/server.xyz.com--"
) | sendmail -t

A wrapper for sendmail can make this job easier, for example, mutt:

mutt -e 'set content_type="text/html"' [email protected] -s "subject" <  message.html

If you are using Dot.Net then the code you need is

Environment.GetFolderPath(Environment.SpecialFolder.InternetCache)

Firebase Notifications doesn't have an API to send messages. Luckily it is built on top of Firebase Cloud Messaging, which has precisely such an API.

With Firebase Notifications and Cloud Messaging, you can send so-called downstream messages to devices in three ways:

1. to specific devices, if you know their device IDs
2. to groups of devices, if you know the registration IDs of the groups
3. to topics, which are just keys that devices can subscribe to

You'll note that there is no way to send to all devices explicitly. You can build such functionality with each of these though, for example: by subscribing the app to a topic when it starts (e.g. /topics/all) or by keeping a list of all device IDs, and then sending the message to all of those.

For sending to a topic you have a syntax error in your command. Topics are identified by starting with /topics/. Since you don't have that in your code, the server interprets allDevices as a device id. Since it is an invalid format for a device registration token, it raises an error.

From the documentation on sending messages to topics:

https://fcm.googleapis.com/fcm/send
Content-Type:application/json
Authorization:key=AIzaSyZ-1u...0GBYzPu7Udno5aA

{
  "to": "/topics/foo-bar",
  "data": {
    "message": "This is a Firebase Cloud Messaging Topic Message!",
   }
}

If anyone gets scrollHeight as undefined, then select elements' 1st subelement: mob_top_menu[0].scrollHeight

You could also use the iframe method, although this is not cross browser compatible (eg. not working in chromium or android and probably others -> instead prompts to download). It works with dataURL's and normal URLS, not sure if the other examples work with dataURLS (please let me know if the other examples work with dataURLS?)

 <iframe class="page-icon preview-pane" frameborder="0" height="352" width="396" src="data:application/pdf;base64, ..DATAURLHERE!... "></iframe>

We tried several things before arriving at an acceptable solution:

xxd -u /usr/bin/xxd | grep 'DF'
00017b0: 4010 8D05 0DFF FF0A 0300 53E3 0610 A003  @.........S.....


root# grep -ibH "df" /usr/bin/xxd
Binary file /usr/bin/xxd matches
xxd -u /usr/bin/xxd | grep -H 'DF'
(standard input):00017b0: 4010 8D05 0DFF FF0A 0300 53E3 0610 A003  @.........S.....

Then found we could get usable results with

xxd -u /usr/bin/xxd > /tmp/xxd.hex ; grep -H 'DF' /tmp/xxd

Note that using a simple search target like 'DF' will incorrectly match characters that span across byte boundaries, i.e.

xxd -u /usr/bin/xxd | grep 'DF'
00017b0: 4010 8D05 0DFF FF0A 0300 53E3 0610 A003  @.........S.....
--------------------^^

So we use an ORed regexp to search for ' DF' OR 'DF ' (the searchTarget preceded or followed by a space char).

The final result seems to be

xxd -u -ps -c 10000000000 DumpFile > DumpFile.hex
egrep ' DF|DF ' Dumpfile.hex

0001020: 0089 0424 8D95 D8F5 FFFF 89F0 E8DF F6FF  ...$............
-----------------------------------------^^
0001220: 0C24 E871 0B00 0083 F8FF 89C3 0F84 DF03  .$.q............

If you are "Rebasing", "Already started rebase" which you want to cancel, just comment (#) all commits listed in rebase editor.

As a result you will get a command line message

Nothing to do

df <- data.frame(x=rnorm(10), y=rnorm(10))
rownames(df) <-  letters[1:10]
df[c('a','b'),]

git fetch
git branch --track branch-name origin/branch-name

First command makes sure you have remote branch in local repository. Second command creates local branch which tracks remote branch. It assumes that your remote name is origin and branch name is branch-name.

--track option is enabled by default for remote branches and you can omit it.

With:

global index_add_counter

You are not defining, just declaring so it's like saying there is a global index_add_counter variable elsewhere, and not create a global called index_add_counter. As you name don't exists, Python is telling you it can not import that name. So you need to simply remove the global keyword and initialize your variable:

index_add_counter = 0

Now you can import it with:

from app import index_add_counter

The construction:

global index_add_counter

is used inside modules' definitions to force the interpreter to look for that name in the modules' scope, not in the definition one:

index_add_counter = 0
def test():
  global index_add_counter # means: in this scope, use the global name
  print(index_add_counter)

The only thing you have to do is adding this line to your sketch

#include <SPI.h>

before #include <Adafruit_MAX31855.h>.

• Do you really write exception safe code? [There's no such thing. Exceptions are a paper shield to errors unless you have a managed environment. This applies to first three questions.]

• Do you know and/or actually use alternatives that work? [Alternative to what? The problem here is people don't separate actual errors from normal program operation. If it's normal program operation (ie a file not found), it's not really error handling. If it's an actual error, there is no way to 'handle' it or it's not an actual error. Your goal here is to find out what went wrong and either stop the spreadsheet and log an error, restart the driver to your toaster, or just pray that the jetfighter can continue flying even when it's software is buggy and hope for the best.]

$("#chk0") is refering to an element with the id chk0. You might try adding id's to the elements. Ids are unique even though the names are the same so that in jQuery you can access a single element by it's id.

Simply skip the error using .values at the end.

affinity_matrix.loc['sums'] = affinity_matrix.sum(axis=0).values

library(plyr)
ddply(data, .(MONTH-YEAR), nrow)

This will give you the answer, if "MONTH-YEAR" is a variable. First, try unique(data$MONTH-YEAR) and see if it returns unique values (no duplicates).

Then above simple split-apply-combine will return what you are looking for.

Had this issue after installing Divio: it had changed my PATH or environment in some way, as it launches a terminal.

The solution in this case was just to do source ~/.bash_profile which should already be setup to get you back to your original pyenv/pyenv-virtualenv state.

To bring more prominence to the useful comment by @johanvdw:

If you want to ensure your your javac file path is always know when cygwin starts, you may edit your .bash_profile file. In this example you would add export PATH=$PATH:"/cygdrive/C/Program Files/Java/jdk1.6.0_23/bin/" somewhere in the file.

When Cygwin starts, it'll search directories in PATH and this one for executable files to run.

Use convert from http://www.imagemagick.org. (Readily supplied as a package in most Linux distributions.)

Yes, you need to have the header Access-Control-Allow-Origin: http://domain.com:3000 or Access-Control-Allow-Origin: * on both the OPTIONS response and the POST response. You should include the header Access-Control-Allow-Credentials: true on the POST response as well.

Your OPTIONS response should also include the header Access-Control-Allow-Headers: origin, content-type, accept to match the requested header.

You have not referenced a jQuery library.

You'll need to include a line similar to this in your HTML:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
