You can Implement this also:- setPage(1, n); where, n = any number.

$products = Mage::getResourceModel('catalog/product_collection')
                ->addAttributeToSelect('*')
                ->addAttributeToSelect(array('name', 'price', 'small_image'))
                ->addFieldToFilter('visibility', Mage_Catalog_Model_Product_Visibility::VISIBILITY_BOTH) //visible only catalog & searchable product
                ->addAttributeToFilter('status', 1) // enabled
                ->setStoreId($storeId)
                ->setOrder('created_at', 'desc')
                ->setPage(1, 6);

HI Jasper,

you can do this:

<?
sprintf("<a href=\"http://www.whatever.com/%s\">Click Here</a>", $param);
?>

Just a shot in the dark(since you did not share the compiler initialization code with us): the way you retrieve the compiler causes the issue. Point your JRE to be inside the JDK as unlike jdk, jre does not provide any tools hence, results in NPE.

If you want to specifically animate the background color of an element, I believe you need to include jQueryUI framework. Then you can do:

$('#myElement').animate({backgroundColor: '#FF0000'}, 'slow');

jQueryUI has some built-in effects that may be useful to you as well.

In this an arrow on compass shows the direction from your location to Kaaba(destination Location)

you can simple use bearingTo in this way.bearing to will give you the direct angle from your location to destination location

  Location userLoc=new Location("service Provider");
    //get longitudeM Latitude and altitude of current location with gps class and  set in userLoc
    userLoc.setLongitude(longitude); 
    userLoc.setLatitude(latitude);
    userLoc.setAltitude(altitude);

   Location destinationLoc = new Location("service Provider");
  destinationLoc.setLatitude(21.422487); //kaaba latitude setting
  destinationLoc.setLongitude(39.826206); //kaaba longitude setting
  float bearTo=userLoc.bearingTo(destinationLoc);

bearingTo will give you a range from -180 to 180, which will confuse things a bit. We will need to convert this value into a range from 0 to 360 to get the correct rotation.

This is a table of what we really want, comparing to what bearingTo gives us

+-----------+--------------+
| bearingTo | Real bearing |
+-----------+--------------+
| 0         | 0            |
+-----------+--------------+
| 90        | 90           |
+-----------+--------------+
| 180       | 180          |
+-----------+--------------+
| -90       | 270          |
+-----------+--------------+
| -135      | 225          |
+-----------+--------------+
| -180      | 180          |
+-----------+--------------+

so we have to add this code after bearTo

// If the bearTo is smaller than 0, add 360 to get the rotation clockwise.

  if (bearTo < 0) {
    bearTo = bearTo + 360;
    //bearTo = -100 + 360  = 260;
}

you need to implements the SensorEventListener and its functions(onSensorChanged,onAcurracyChabge) and write all the code inside onSensorChanged

Complete code is here for Direction of Qibla compass

if (bearTo < 0) {
    bearTo = bearTo + 360;
    //bearTo = -100 + 360  = 260;
}

//This is where we choose to point it
float direction = bearTo - head;

// If the direction is smaller than 0, add 360 to get the rotation clockwise.
if (direction < 0) {
    direction = direction + 360;
}
 tvHeading.setText("Heading: " + Float.toString(degree) + " degrees" );

RotateAnimation raQibla = new RotateAnimation(currentDegreeNeedle, direction, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);

echo "obase=16; 34" | bc

If you want to filter a whole file of integers, one per line:

( echo "obase=16" ; cat file_of_integers ) | bc

Using inputStream.available()

It is always acceptable for System.in.available() to return 0.

I've found the opposite - it always returns the best value for the number of bytes available. Javadoc for InputStream.available():

Returns an estimate of the number of bytes that can be read (or skipped over) 
from this input stream without blocking by the next invocation of a method for 
this input stream.

An estimate is unavoidable due to timing/staleness. The figure can be a one-off underestimate because new data are constantly arriving. However it always "catches up" on the next call - it should account for all arrived data, bar that arriving just at the moment of the new call. Permanently returning 0 when there are data fails the condition above.

First Caveat: Concrete subclasses of InputStream are responsible for available()

InputStream is an abstract class. It has no data source. It's meaningless for it to have available data. Hence, javadoc for available() also states:

The available method for class InputStream always returns 0.

This method should be overridden by subclasses.

And indeed, the concrete input stream classes do override available(), providing meaningful values, not constant 0s.

Second Caveat: Ensure you use carriage-return when typing input in Windows.

If using System.in, your program only receives input when your command shell hands it over. If you're using file redirection/pipes (e.g. somefile > java myJavaApp or somecommand | java myJavaApp ), then input data are usually handed over immediately. However, if you manually type input, then data handover can be delayed. E.g. With windows cmd.exe shell, the data are buffered within cmd.exe shell. Data are only passed to the executing java program following carriage-return (control-m or <enter>). That's a limitation of the execution environment. Of course, InputStream.available() will return 0 for as long as the shell buffers the data - that's correct behaviour; there are no available data at that point. As soon as the data are available from the shell, the method returns a value > 0. NB: Cygwin uses cmd.exe too.

Simplest solution (no blocking, so no timeout required)

Just use this:

    byte[] inputData = new byte[1024];
    int result = is.read(inputData, 0, is.available());  
    // result will indicate number of bytes read; -1 for EOF with no data read.

OR equivalently,

    BufferedReader br = new BufferedReader(new InputStreamReader(System.in, Charset.forName("ISO-8859-1")),1024);
    // ...
         // inside some iteration / processing logic:
         if (br.ready()) {
             int readCount = br.read(inputData, bufferOffset, inputData.length-bufferOffset);
         }

Richer Solution (maximally fills buffer within timeout period)

Declare this:

public static int readInputStreamWithTimeout(InputStream is, byte[] b, int timeoutMillis)
     throws IOException  {
     int bufferOffset = 0;
     long maxTimeMillis = System.currentTimeMillis() + timeoutMillis;
     while (System.currentTimeMillis() < maxTimeMillis && bufferOffset < b.length) {
         int readLength = java.lang.Math.min(is.available(),b.length-bufferOffset);
         // can alternatively use bufferedReader, guarded by isReady():
         int readResult = is.read(b, bufferOffset, readLength);
         if (readResult == -1) break;
         bufferOffset += readResult;
     }
     return bufferOffset;
 }

Then use this:

    byte[] inputData = new byte[1024];
    int readCount = readInputStreamWithTimeout(System.in, inputData, 6000);  // 6 second timeout
    // readCount will indicate number of bytes read; -1 for EOF with no data read.

Other answers describe the purposes. Here are the characters each function will actually convert:

control = '\x00\x01\x02\x03\x04\x05\x06\x07\x08\x09\x0A\x0B\x0C\x0D\x0E\x0F'
        + '\x10\x11\x12\x13\x14\X15\x16\x17\x18\x19\x1A\x1B\x1C\x1D\x1E\x1F'
                                                                    + '\x7F'
encodeURI         (control + ' "%<>[\\]^`{|}'                             )
encodeURIComponent(control + ' "%<>[\\]^`{|}' + '#$&,:;=?' + '+/@'        )
escape            (control + ' "%<>[\\]^`{|}' + '#$&,:;=?' +       "!'()~")

All characters above are converted to percent-hexadecimal codes. Space to %20, percent to %25, etc. The characters below pass through unchanged.

Here are the characters the functions will NOT convert:

pass_thru = '*-._0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'

encodeURI         (pass_thru + '#$&,:;=?' + '+/@' + "!'()~")
encodeURIComponent(pass_thru +                      "!'()~")
escape            (pass_thru +              '+/@'          )

For your current structure, you could also try the following:

select cash.Country, cash.Value, cheque.Value, cash.Value + cheque.Value as [Total]
from Cash
join Cheque
on cash.Country = cheque.Country

I think I prefer a union between the two tables, and a group by on the country name as mentioned above.

But I would also recommend normalising your tables. Ideally you'd have a country table, with Id and Name, and a payments table with: CountryId (FK to countries), Total, Type (cash/cheque)

If you'd rather transform your array, then the iterator parameter of underscore's map function is also passed the index as a second argument. So:

_.map([1, 4, 2, 66, 444, 9], function(value, index){ return index + ':' + value; });

... returns:

["0:1", "1:4", "2:2", "3:66", "4:444", "5:9"]

You can't... an array's size is always fixed in Java. Typically instead of using an array, you'd use an implementation of List<T> here - usually ArrayList<T>, but with plenty of other alternatives available.

You can create an array from the list as a final step, of course - or just change the signature of the method to return a List<T> to start with.

Try like this.

<div style="overflow-y: scroll; height:400px;">

Just add quotes around the size in your code. Using this you can use percentage in width, height

input: {
    width: '80%'
}

You probably looking for something like this.

FileInputStream in = new FileInputStream("inputFile.txt");
BufferedReader br = new BufferedReader(new InputStreamReader(in));

You can try this instead


var myu = document.getElementById('myu').value;
var myp = document.getElementById('myp').value;
window.opener.location.href='myurl.php?myu='+ myu +'&myp='+ myp;

Note: Do not use this method to pass sensitive information like username, password.

the secure way is encrypt your sensitive data by AES and the encryption key is derivation by password-based key derivation function (PBE), the master password used to encrypt/decrypt the encrypt key for AES.

master password -> secure key-> encrypt data by the key

You can use pbkdf2

from PBKDF2 import PBKDF2
from Crypto.Cipher import AES
import os
salt = os.urandom(8)    # 64-bit salt
key = PBKDF2("This passphrase is a secret.", salt).read(32) # 256-bit key
iv = os.urandom(16)     # 128-bit IV
cipher = AES.new(key, AES.MODE_CBC, iv)

make sure to store the salt/iv/passphrase , and decrypt using same salt/iv/passphase

Weblogic used similar approach to protect passwords in config files

According to Java Persistence with Hibernate

mapping collections of value types with annotations [...]. At the time of writing it isn't part of the Java Persistence standard

If you were using Hibernate, you could do something like:

@org.hibernate.annotations.CollectionOfElements(
    targetElement = java.lang.String.class
)
@JoinTable(
    name = "foo",
    joinColumns = @JoinColumn(name = "foo_id")
)
@org.hibernate.annotations.IndexColumn(
    name = "POSITION", base = 1
)
@Column(name = "baz", nullable = false)
private List<String> arguments = new ArrayList<String>();

Update: Note, this is now available in JPA2.

sizes=( $(cat files.txt | xargs ls -l | cut -c 23-30) )
total=$(( $(IFS="+"; echo "${sizes[*]}") ))

Or you could just sum them as you read the sizes

declare -i total=0
while read x; total+=x; done < <( cat files.txt | xargs ls -l | cut -c 23-30 )

If you don't care about bite sizes and blocks is OK, then just

declare -i total=0
while read s junk; total+=s; done < <( cat files.txt | xargs ls -s )

instead of using:

Application.Wait(Now + #0:00:01#)

i prefer:

Application.Wait(Now + TimeValue("00:00:01"))

because it is a lot easier to read afterwards.

def player(game_over):
    do something here
    game_over = check_winner() #Here we tell check_winner to run and tell us what game_over should be, either true or false
    if not game_over: 
        computer(game_over)  #We are only going to do this if check_winner comes back as False

def check_winner(): 
    check something
    #here needs to be an if / then statement deciding if the game is over, return True if over, false if not
    if score == 100:
        return True
    else:
        return False

def computer(game_over):
    do something here
    game_over = check_winner() #Here we tell check_winner to run and tell us what game_over should be, either true or false
    if not game_over:
        player(game_over) #We are only going to do this if check_winner comes back as False

game_over = False   #We need a variable to hold wether the game is over or not, we'll start it out being false.
player(game_over)   #Start your loops, sending in the status of game_over

Above is a pretty simple example... I made up a statement for check_winner using score = 100 to denote the game being over.

You will want to use similar method of passing score into check_winner, using game_over = check_winner(score). Then you can create a score at the beginning of your program and pass it through to computer and player just like game_over is being handled.

If i say without loop, i can use GOTO statement for delete large amount of records using sql server. exa.

 IsRepeat:
    DELETE TOP (10000)
    FROM <TableName>
    IF @@ROWCOUNT > 0
         GOTO IsRepeat

like this way you can delete large amount of data with smaller size of delete.

let me know if requires more information.

If you have a SSHClient, you can also use open_sftp():

import paramiko


# lets say you have SSH client...
client = paramiko.SSHClient()

sftp = client.open_sftp()

# then you can use upload & download as shown above
...

You could really, really, really optimize your code a lot by paying the price of creating the delegate only once (there's also no need to instantiate the class to call an static method). I've done something very similar, and I just cache a delegate to the "Run" method with the help of a helper class :-). It looks like this:

static class Indent{    
     public static void Run(){
         // implementation
     }
     // other helper methods
}

static class MacroRunner {

    static MacroRunner() {
        BuildMacroRunnerList();
    }

    static void BuildMacroRunnerList() {
        macroRunners = System.Reflection.Assembly.GetExecutingAssembly()
            .GetTypes()
            .Where(x => x.Namespace.ToUpper().Contains("MACRO"))
            .Select(t => (Action)Delegate.CreateDelegate(
                typeof(Action), 
                null, 
                t.GetMethod("Run", System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.Public)))
            .ToList();
    }

    static List<Action> macroRunners;

    public static void Run() {
        foreach(var run in macroRunners)
            run();
    }
}

It is MUCH faster this way.

If your method signature is different from Action you could replace the type-casts and typeof from Action to any of the needed Action and Func generic types, or declare your Delegate and use it. My own implementation uses Func to pretty print objects:

static class PrettyPrinter {

    static PrettyPrinter() {
        BuildPrettyPrinterList();
    }

    static void BuildPrettyPrinterList() {
        printers = System.Reflection.Assembly.GetExecutingAssembly()
            .GetTypes()
            .Where(x => x.Name.EndsWith("PrettyPrinter"))
            .Select(t => (Func<object, string>)Delegate.CreateDelegate(
                typeof(Func<object, string>), 
                null, 
                t.GetMethod("Print", System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.Public)))
            .ToList();
    }

    static List<Func<object, string>> printers;

    public static void Print(object obj) {
        foreach(var printer in printers)
            print(obj);
    }
}

You can use dialog.setCanceledOnTouchOutside(true); which will close the dialog if you touch outside of the dialog.

Something like,

  Dialog dialog = new Dialog(context)
  dialog.setCanceledOnTouchOutside(true);

Or if your Dialog in non-model then,

1 - Set the flag-FLAG_NOT_TOUCH_MODAL for your dialog's window attribute

Window window = this.getWindow();
window.setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL,
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);

2 - Add another flag to windows properties,, FLAG_WATCH_OUTSIDE_TOUCH - this one is for dialog to receive touch event outside its visible region.

3 - Override onTouchEvent() of dialog and check for action type. if the action type is 'MotionEvent.ACTION_OUTSIDE' means, user is interacting outside the dialog region. So in this case, you can dimiss your dialog or decide what you wanted to perform. view plainprint?

public boolean onTouchEvent(MotionEvent event)  
{  

       if(event.getAction() == MotionEvent.ACTION_OUTSIDE){  
        System.out.println("TOuch outside the dialog ******************** ");  
               this.dismiss();  
       }  
       return false;  
}  

For more info look at How to dismiss a custom dialog based on touch points? and How to dismiss your non-modal dialog, when touched outside dialog region

Note that I don't recommend a fixed IP for containers in Docker unless you're doing something that allows routing from outside to the inside of your container network (e.g. macvlan). DNS is already there for service discovery inside of the container network and supports container scaling. And outside the container network, you should use exposed ports on the host. With that disclaimer, here's the compose file you want:

version: '2'

services:
  mysql:
    container_name: mysql
    image: mysql:latest
    restart: always
    environment:
      - MYSQL_ROOT_PASSWORD=root

There may be different reason for reported issue, few days back also face this issue 'duplicate jar', after upgrading studio. From all stackoverflow I tried all the suggestion but nothing worked for me.

But this is for sure some duplicate jar is there, For me it was present in one library libs folder as well as project libs folder. So I removed from project libs folder as it was not required here. So be careful while updating the studio, and try to understand all the gradle error.

and I have a sensor table that has lots of mostly static stuff about the sensor but the relevant fields are these:

Sensors->(idSensor,Description,tvLastUpdate,tvLastValue,...)

The tvLastupdate and tvLastValue are set in a trigger on inserts to the SensorReadings table. I always have direct access to these values without needing to do any expensive queries. This does denormalize slightly. The query is trivial:

SELECT idSensor,Description,tvLastUpdate,tvLastValue 
FROM Sensors

I use this method for data that is queried often. In my case I have a sensor table, and a large event table, that have data coming in at the minute level AND dozens of machines are updating dashboards and graphs with that data. With my data scenario the trigger-and-cache method works well.

Ehm. I had moved my site/files to a different folder. Without changing the path in the IIS website.

You may all laugh now.

urllib is a standard library, you do not have to install it. Simply import urllib

An undirected graph without cycle has |E| < |V|-1.

public boolean hasCycle(Graph g) {

   int totalEdges = 0;
   for(Vertex v : g.getVertices()) {
     totalEdges += v.getNeighbors().size();
   }
   return totalEdges/2 > g.getVertices().size - 1;

}

New functionality in the framework and support libs allow exactly this. There are three 'pieces of the puzzle':

1. Using Toolbar so that you can embed your action bar into your view hierarchy.
2. Making DrawerLayout fitsSystemWindows so that it is layed out behind the system bars.
3. Disabling Theme.Material's normal status bar coloring so that DrawerLayout can draw there instead.

I'll assume that you will use the new appcompat.

First, your layout should look like this:

<!-- The important thing to note here is the added fitSystemWindows -->
<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/my_drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">

    <!-- Your normal content view -->
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <!-- We use a Toolbar so that our drawer can be displayed
             in front of the action bar -->
        <android.support.v7.widget.Toolbar  
            android:id="@+id/my_awesome_toolbar"
            android:layout_height="wrap_content"
            android:layout_width="match_parent"
            android:minHeight="?attr/actionBarSize"
            android:background="?attr/colorPrimary" />

        <!-- The rest of your content view -->

    </LinearLayout>

    <!-- Your drawer view. This can be any view, LinearLayout
         is just an example. As we have set fitSystemWindows=true
         this will be displayed under the status bar. -->
    <LinearLayout
        android:layout_width="304dp"
        android:layout_height="match_parent"
        android:layout_gravity="left|start"
        android:fitsSystemWindows="true">

        <!-- Your drawer content -->

    </LinearLayout>

</android.support.v4.widget.DrawerLayout>

Then in your Activity/Fragment:

public void onCreate(Bundled savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Your normal setup. Blah blah ...

    // As we're using a Toolbar, we should retrieve it and set it
    // to be our ActionBar
    Toolbar toolbar = (...) findViewById(R.id.my_awesome_toolbar);
    setSupportActionBar(toolbar);

    // Now retrieve the DrawerLayout so that we can set the status bar color.
    // This only takes effect on Lollipop, or when using translucentStatusBar
    // on KitKat.
    DrawerLayout drawerLayout = (...) findViewById(R.id.my_drawer_layout);
    drawerLayout.setStatusBarBackgroundColor(yourChosenColor);
}

Then you need to make sure that the DrawerLayout is visible behind the status bar. You do that by changing your values-v21 theme:

values-v21/themes.xml

<style name="Theme.MyApp" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowDrawsSystemBarBackgrounds">true</item>
    <item name="android:statusBarColor">@android:color/transparent</item>
    <item name="android:windowTranslucentStatus">true</item>
</style>

Note: If a <fragment android:name="fragments.NavigationDrawerFragment"> is used instead of

<LinearLayout
    android:layout_width="304dp"
    android:layout_height="match_parent"
    android:layout_gravity="left|start"
    android:fitsSystemWindows="true">

    <!-- Your drawer content -->

</LinearLayout>

the actual layout, the desired effect will be achieved if you call fitsSystemWindows(boolean) on a view that you return from onCreateView method.

@Override
public View onCreateView(LayoutInflater inflater, 
                         ViewGroup container,
                         Bundle savedInstanceState) {
    View mDrawerListView = inflater.inflate(
        R.layout.fragment_navigation_drawer, container, false);
    mDrawerListView.setFitsSystemWindows(true);
    return mDrawerListView;
}

As mentioned in Takahiko Kawasaki's answer, java represents Unicode strings in the form of modified UTF-8 and in JVM-Spec CONSTANT_UTF8_info Structure, 2 bytes are allocated to length (and not the no. of characters of String).
To extend the answer, the ASM jvm bytecode library's putUTF8 method, contains this:

public ByteVector putUTF8(final String stringValue) {
    int charLength = stringValue.length();
    if (charLength > 65535) {   
   // If no. of characters> 65535, than however UTF-8 encoded length, wont fit in 2 bytes.
      throw new IllegalArgumentException("UTF8 string too large");
    }
    for (int i = 0; i < charLength; ++i) {
      char charValue = stringValue.charAt(i);
      if (charValue >= '\u0001' && charValue <= '\u007F') {
        // Unicode code-point encoding in utf-8 fits in 1 byte.
        currentData[currentLength++] = (byte) charValue;
      } else {
        // doesnt fit in 1 byte.
        length = currentLength;
        return encodeUtf8(stringValue, i, 65535);
      }
    }
    ...
}

But when code-point mapping > 1byte, it calls encodeUTF8 method:

final ByteVector encodeUtf8(final String stringValue, final int offset, final int maxByteLength /*= 65535 */) {
    int charLength = stringValue.length();
    int byteLength = offset;
    for (int i = offset; i < charLength; ++i) {
      char charValue = stringValue.charAt(i);
      if (charValue >= 0x0001 && charValue <= 0x007F) {
        byteLength++;
      } else if (charValue <= 0x07FF) {
        byteLength += 2;
      } else {
        byteLength += 3;
      }
    }
   ...
}

In this sense, the max string length is 65535 bytes, i.e the utf-8 encoding length. and not char count
You can find the modified-Unicode code-point range of JVM, from the above utf8 struct link.

The top answer here seems to be an OS dependent answer; for a more portable solution you can write up a quick sleep function using the ctime header file (although this may be a poor implementation on my part).

#include <iostream>
#include <ctime>

using namespace std;

void sleep(float seconds){
    clock_t startClock = clock();
    float secondsAhead = seconds * CLOCKS_PER_SEC;
    // do nothing until the elapsed time has passed.
    while(clock() < startClock+secondsAhead);
    return;
}
int main(){

    cout << "Next string coming up in one second!" << endl;
    sleep(1.0);
    cout << "Hey, what did I miss?" << endl;

    return 0;
}

For Windows users: You can do as RTA said or through command line do this: Navigate to the locaiton of the eclipse executable then run:

 eclipse.lnk -clean

First check the name of your executable using the command 'dir' on its path

From the C++0x draft Standard.

$5.3.5/2 - "[...]In either alternative, the value of the operand of delete may be a null pointer value.[...'"

Of course, no one would ever do 'delete' of a pointer with NULL value, but it is safe to do. Ideally one should not have code that does deletion of a NULL pointer. But it is sometimes useful when deletion of pointers (e.g. in a container) happens in a loop. Since delete of a NULL pointer value is safe, one can really write the deletion logic without explicit checks for NULL operand to delete.

As an aside, C Standard $7.20.3.2 also says that 'free' on a NULL pointer does no action.

The free function causes the space pointed to by ptr to be deallocated, that is, made available for further allocation. If ptr is a null pointer, no action occurs.

your can query woocommerce programatically you can even add a product to your shopping cart. I'm sure you can figure out how to interact with woocommerce cart once you read the code. how to interact with woocommerce cart programatically

====================================

<?php

add_action('wp_loaded', 'add_product_to_cart');
function add_product_to_cart()
{
    global $wpdb;

    if (!is_admin()) {


        $product_id = wc_get_product_id_by_sku('L3-670115');

        $found = false;

        if (is_user_logged_in()) {

You can use max(value, run)

The function max takes any number of arguments, or (alternatively) an iterable, and returns the maximum value.

future.utils allows for python 2 and 3 compatibility.

# Python 2 and 3: option 3
from future.utils import iteritems
heights = {'man': 185,'lady': 165}
for (key, value) in iteritems(heights):
    print(key,value)

>>> ('lady', 165)
>>> ('man', 185)

See this link: https://python-future.org/compatible_idioms.html

I like to use:

(strlen(string) + 1 ) * sizeof(char)

This will give you the buffer size in bytes. You can use this with snprintf() may help:

const char* message = "%s, World!";
char* string = (char*)malloc((strlen(message)+1))*sizeof(char));
snprintf(string, (strlen(message)+1))*sizeof(char), message, "Hello");

Cheers! Function: size_t strlen (const char *s)

I've recently found even more interesting way to create any ValueNode or ContainerNode (Jackson v2.3).

ObjectNode node = JsonNodeFactory.instance.objectNode();

They have the same effect on normal web browser rendering engines, but there is a fundamental difference between them.

As the author writes in a discussion list post:

Think of three different situations:

• web browsers
• blind people
• mobile phones

"Bold" is a style - when you say "bold a word", people basically know that it means to add more, let's say "ink", around the letters until they stand out more amongst the rest of the letters.

That, unfortunately, means nothing to a blind person. On mobile phones and other PDAs, text is already bold because screen resolution is very small. You can't bold a bold without screwing something up.

<b> is a style - we know what "bold" is supposed to look like.

<strong> however is an indication of how something should be understood. "Strong" could (and often does) mean "bold" in a browser, but it could also mean a lower tone for a speaking program like Jaws (for blind people) or be represented by an underline (since you can't bold a bold) on a Palm Pilot.

HTML was never meant to be about styles. Do some searches for "Tim Berners-Lee" and "the semantic web." <strong> is semantic—it describes the text it surrounds (e.g., "this text should be stronger than the rest of the text you've displayed") as opposed to describing how the text it surrounds should be displayed (e.g., "this text should be bold").

One solution would be to flash two variables into the session:

1. The message itself
2. The "class" of your alert

for example:

Session::flash('message', 'This is a message!'); 
Session::flash('alert-class', 'alert-danger'); 

Then in your view:

@if(Session::has('message'))
<p class="alert {{ Session::get('alert-class', 'alert-info') }}">{{ Session::get('message') }}</p>
@endif

Note I've put a default value into the Session::get(). that way you only need to override it if the warning should be something other than the alert-info class.

(that is a quick example, and untested :) )

Parameters take input before arguments. What you should do instead is add a parameter that accepts an array, and make it the first position parameter. ex:

param(
    [Parameter(Position = 0)]
    [string[]]$Hosts,
    [string]$VLAN
    )

foreach ($i in $Hosts)  
{ 
    Do-Stuff $i
}

Then call it like:

.\script.ps1 host1, host2, host3 -VLAN 2

Notice the comma between the values. This collects them in an array

On Windows also check whether the file is not encrypted using EFS. I had the same problem untill I decrypted the file manualy.

In respect of claviska answer - if you want to show uploaded file name in a basic file upload you can do it in inputs' onchange event. Just use this code:

 <label class="btn btn-default">
                    Browse...
                    <span id="uploaded-file-name" style="font-style: italic"></span>
                    <input id="file-upload" type="file" name="file"
                           onchange="$('#uploaded-file-name').text($('#file-upload')[0].value);" hidden>
 </label>

This jquery JS code is responsible will retrieving uploaded file name:

$('#file-upload')[0].value

Or with vanilla JS:

document.getElementById("file-upload").value

mm is minutes. You want MM for months:

SimpleDateFormat sdf1 = new SimpleDateFormat("dd-MM-yyyy");

Don't feel bad - this exact mistake comes up a lot.

Deletion of a topic has been supported since 0.8.2.x version. You have to enable topic deletion (setting delete.topic.enable to true) on all brokers first.

Note: Ever since 1.0.x, the functionality being stable, delete.topic.enable is by default true.

Follow this step by step process for manual deletion of topics

1. Stop Kafka server
2. Delete the topic directory, on each broker (as defined in the logs.dirs and log.dir properties) with rm -rf command
3. Connect to Zookeeper instance: zookeeper-shell.sh host:port
4. From within the Zookeeper instance:
   1. List the topics using: ls /brokers/topics
   2. Remove the topic folder from ZooKeeper using: rmr /brokers/topics/yourtopic
   3. Exit the Zookeeper instance (Ctrl+C)
5. Restart Kafka server
6. Confirm if it was deleted or not by using this command kafka-topics.sh --list --zookeeper host:port

In general, one doesn't expand out log(a + b); you just deal with it as is. That said, there are occasionally circumstances where it makes sense to use the following identity:

log(a + b) = log(a * (1 + b/a)) = log a + log(1 + b/a)

(In fact, this identity is often used when implementing log in math libraries).

Although other answers prove the requirement, they don't explain why the requirement exists.

The JLS mentions why in §15.27.2:

The restriction to effectively final variables prohibits access to dynamically-changing local variables, whose capture would likely introduce concurrency problems.

To lower risk of bugs, they decided to ensure captured variables are never mutated.

For .NET 4.0 and higher, you can compare elements in array or tuples using the StructuralComparisons type:

object[] a1 = { "string", 123, true };
object[] a2 = { "string", 123, true };
        
Console.WriteLine (a1 == a2);        // False (because arrays is reference types)
Console.WriteLine (a1.Equals (a2));  // False (because arrays is reference types)
        
IStructuralEquatable se1 = a1;
//Next returns True
Console.WriteLine (se1.Equals (a2, StructuralComparisons.StructuralEqualityComparer)); 

Knuth has written a paper "Structured programming with GOTO statements", you can get it e.g. from here. You'll find many examples there.

I resolved this kind of issue like this: I went into my XML layout file, cut the line of code that was generating the error. Then I saved the file, and pasted the code back in. The error was gone.

There are more than a few ways. I'll list them in order of inverted preference (i.e., best first, worst last):

1. Treat it like a module: import file. This is good because it's secure, fast, and maintainable. Code gets reused as it's supposed to be done. Most Python libraries run using multiple methods stretched over lots of files. Highly recommended. Note that if your file is called file.py, your import should not include the .py extension at the end.
2. The infamous (and unsafe) exec command: Insecure, hacky, usually the wrong answer. Avoid where possible.
   • execfile('file.py') in Python 2
   • exec(open('file.py').read()) in Python 3
3. Spawn a shell process: os.system('python file.py'). Use when desperate.

$('.close').click(function() {
  //Code to be executed when close is clicked
  $('#result').html('yes,result');
});

If your iframe is from another domain, (cross domain), the other answers are not going to help you... you will simply need to use this:

Java compiler imports 3 packages by default. 1. The package without name 2. The java.lang package(That's why you can declare String, Integer, System classes without import) 3. The current package (current file's package)

That's why you don't need to declare import statement for the java.lang package.

I also wanted to do this, but with a method that receives a BOOL parameter. Wrapping the bool value with NSNumber, FAILED TO PASS THE VALUE. I have no idea why.

So I ended up doing a simple hack. I put the required parameter in another dummy function and call that function using the performSelector, where withObject = nil;

[self performSelector:@selector(dummyCaller:) withObject:nil afterDelay:5.0];

-(void)dummyCaller {

[self myFunction:YES];

Design a spinner for common use, just data input and get user's choosen, advantages :

1. Keep spinner style the same for app.
2. Start spinner anywhere.
3. Easy to handle linked spinner(start ReuseSpinner again with different data).

My demo example : ReuseSpinner
pass data to ReuseSpinner :

Intent intent = new Intent(MainActivity.this, SpinnerActivity.class);
intent.putExtra(SpinnerActivity.Extra_Resource, arrayList);
startActivityForResult(intent, mRequestCode_select_country_prompt);

get user's choosen :

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);

        if(requestCode == mRequestCode_select_country && resultCode == RESULT_OK){
            if(data != null){
                Map.Entry<String,String> entry = (Map.Entry<String,String>) data.getSerializableExtra(SpinnerActivity.Result_Data);
                if(entry != null){
                    Log.i(TAG, String.format("get result -> key:%s , value:%s", entry.getKey(), entry.getValue()));

                }
            }
        }
    }

You can use bytes(list).decode() to do this - and list(string.encode()) to get the values back.

In layman terms it's strongly structured vs unstructured, which implies that you have different degrees of adaptability for your DB. Differences arise in indexation particularly as you need to ensure that a certain reference index can link to a another item -> this a relation. The more strict structure of relational DB comes from this requirement.

To note that NosDB apaprently provides both relational and non relational DBs and a way to query both http://www.alachisoft.com/nosdb/sql-cheat-sheet.html

Shortest way to get all dictionary/object values:

Object.keys(dict).map(k => dict[k]);

To make things clear, you need to know two facts:

1. The instanceof operator tests whether the prototype property of a constructor appears anywhere in the prototypes chain of an object. In most cases this mean that the object was created by using this constructor or on of its descendant. But also prototype may be set explicitly by Object.setPrototypeOf() method (ECMAScript 2015) or by the __proto__ property (old browsers, deprecated). Changing the prototype of an object is not recommended though, because of performance issues.

Thus instanceof is applicable only to objects. In most cases you aren't using constructors to create strings or numbers. You can. But you almost never do.

Also instanceof can't check, exactly which constructor was used to create the object, but will return true, even if object is derived from class which being checked. In most cases this is the desired behavior, but sometimes it's not. So you need to keep that mind.

Another problem is that different scopes have different execution environments. This means that they have different built-ins (different global object, different constructors, etc.). This may result in unexpected results.

For example, [] instanceof window.frames[0].Array will return false, because Array.prototype !== window.frames[0].Array and arrays inherit from the former.
Also, it cannot be used on undefined value, because it don't have a prototype.

2. The typeof operator tests whether value belong to one of six basic types: "number", "string", "boolean", "object", "function" or "undefined". Where the string "object" belong all objects (except functions, which are objects, but have its own value in typeof operator), and also "null" value and arrays (for "null" it's a bug, but this bug is so old, so it's become a standard). It doesn't rely on constructors and can be used even if value is undefined. But it's doesn't give any details about objects. So if you needed it, go to instanceof.

Now let's talk about one tricky thing. What if you use constructor to create a primitive type?

let num = new Number(5);
console.log(num instanceof Number); // print true
console.log(typeof num); // print object
num++; //num is object right now but still can be handled as number
//and after that:
console.log(num instanceof Number); // print false
console.log(typeof num); // print number

Seems like magic. But it is not. It's so-called boxing (wrapping primitive value by object) and unboxing (extracting wrapped primitive value from object). Such kind of code seems to be "a bit" fragile. Of course you can just avoid creating primitive type with constructors. But there is another possible situation, when boxing may hit you. When you use Function.call() or Function.apply() on a primitive type.

function test(){
  console.log(typeof this);
} 
test.apply(5);

To avoiding this you can use strict mode:

function test(){
  'use strict';
  console.log(typeof this);
} 
test.apply(5);

upd: Since ECMAScript 2015, there is one more type called Symbol, which has its own typeof == "symbol".

console.log(typeof Symbol());
// expected output: "symbol"

You can read about it on MDN: (Symbol, typeof).

$('#inputfield').change(function() { 
    dosomething();
});

In my case I had the following by mistake in my connection string:

Encrypt=True

Changing to

Encrypt=False

Solved the problem

"Server=***;Initial Catalog=***;Persist Security Info=False;User  ID=***;Password=***;MultipleActiveResultSets=False;Encrypt=False;TrustServerCertificate=False;Connection Timeout=30;"

If you'd like to initialize the array to values other than 0, with gcc you can do:

int array[1024] = { [ 0 ... 1023 ] = -1 };

This is a GNU extension of C99 Designated Initializers. In older GCC, you may need to use -std=gnu99 to compile your code.

You're asking it to parse the JSON text something (not "something"). That's invalid JSON, strings must be in double quotes.

If you want an equivalent to your first example:

var s = '"something"';
var result = JSON.parse(s);

Linq (for s&g's):

var test = "This is the string I'm looking for";
var found = strArray.Any(x=>x == test);

or, depending on requirements

var found = strArray.Any(
    x=>x.Equals(test, StringComparison.OrdinalIgnoreCase));

Hiding on the Client Side with javascript

Using plain old javascript, you can easily hide the same element in this manner:

var myDivElem = document.getElementById("myDiv");
myDivElem.style.display = "none";

Then to show again:

myDivElem.style.display = "";

jQuery makes hiding elements a little simpler if you prefer to use jQuery:

var myDiv = $("#<%=myDiv.ClientID%>");
myDiv.hide();

... and to show:

myDiv.show();

Imagine you are developing a web-application and you decide to decouple the functionality from the presentation of the application, because it affords greater freedom.

You create an API and let others implement their own front-ends over it as well. What you just did here is implement an SOA methodology, i.e. using web-services.

Web services make functional building-blocks accessible over standard Internet protocols independent of platforms and programming languages.

So, you design an interchange mechanism between the back-end (web-service) that does the processing and generation of something useful, and the front-end (which consumes the data), which could be anything. (A web, mobile, or desktop application, or another web-service). The only limitation here is that the front-end and back-end must "speak" the same "language".

That's where SOAP and REST come in. They are standard ways you'd pick communicate with the web-service.

SOAP:

SOAP internally uses XML to send data back and forth. SOAP messages have rigid structure and the response XML then needs to be parsed. WSDL is a specification of what requests can be made, with which parameters, and what they will return. It is a complete specification of your API.

REST:

REST is a design concept.

The World Wide Web represents the largest implementation of a system conforming to the REST architectural style.

It isn't as rigid as SOAP. RESTful web-services use standard URIs and methods to make calls to the webservice. When you request a URI, it returns the representation of an object, that you can then perform operations upon (e.g. GET, PUT, POST, DELETE). You are not limited to picking XML to represent data, you could pick anything really (JSON included)

Flickr's REST API goes further and lets you return images as well.

JSON and XML, are functionally equivalent, and common choices. There are also RPC-based frameworks like GRPC based on Protobufs, and Apache Thrift that can be used for communication between the API producers and consumers. The most common format used by web APIs is JSON because of it is easy to use and parse in every language.

Just in case, to check variables you can use

$> mysqladmin variables -u user -p 

This will display the current variables, in this case max_allowed_packet, and as someone said in another answer you can set it temporarily with

mysql> SET GLOBAL max_allowed_packet=1072731894

In my case the cnf file was not taken into account and I don't know why, so the SET GLOBAL code really helped.

Don't use keyworks like "ad", "ads", "advertise", etc. in image url or image class. Adblock block them automatically.

Since you declare sample inside the anonymous function you pass to ready, it is scoped to that function.

You then pass a string to setTimeout which is evaled after 2 seconds. This takes place outside the current scope, so it can't find the function.

Only pass functions to setTimeout, using eval is inefficient and hard to debug.

setTimeout(sample,2000)

A standard http GET request should do it. Then you can use JSON.parse() to make it into a json object.

function Get(yourUrl){
    var Httpreq = new XMLHttpRequest(); // a new request
    Httpreq.open("GET",yourUrl,false);
    Httpreq.send(null);
    return Httpreq.responseText;          
}

then

var json_obj = JSON.parse(Get(yourUrl));
console.log("this is the author name: "+json_obj.author_name);

that's basically it

Yes, rightly said. Hive does not support UPDATE option. But the following alternative could be used to achieve the result:

Update records in a partitioned Hive table:

1. The main table is assumed to be partitioned by some key.
2. Load the incremental data (the data to be updated) to a staging table partitioned with the same keys as the main table.

3. Join the two tables (main & staging tables) using a LEFT OUTER JOIN operation as below:

   insert overwrite table main_table partition (c,d) select t2.a, t2.b, t2.c,t2.d from staging_table t2 left outer join main_table t1 on t1.a=t2.a;

In the above example, the main_table & the staging_table are partitioned using the (c,d) keys. The tables are joined via a LEFT OUTER JOIN and the result is used to OVERWRITE the partitions in the main_table.

A similar approach could be used in the case of un-partitioned Hive table UPDATE operations too.

To elaborate on Sami's answer:

From the docs:

class Payload(object):
    def __init__(self, action, method, data):
        self.action = action
        self.method = method
        self.data = data

import json

def as_payload(dct):
    return Payload(dct['action'], dct['method'], dct['data'])

payload = json.loads(message, object_hook = as_payload)

My objection to the

.__dict__ 

solution is that while it does the job and is concise, the Payload class becomes totally generic - it doesn't document its fields.

For example, if the Payload message had an unexpected format, instead of throwing a key not found error when the Payload was created, no error would be generated until the payload was used.

I think the best practice is to have single primary constructor to which the overloaded constructors refer to by calling this() with the relevant parameter defaults. The reason for this is that it makes it much clearer what is the constructed state of the object is - really you can think of the primary constructor as the only real constructor, the others just delegate to it

One example of this might be JTable - the primary constructor takes a TableModel (plus column and selection models) and the other constructors call this primary constructor.

For subclasses where the superclass already has overloaded constructors, I would tend to assume that it is reasonable to treat any of the parent class's constructors as primary and think it is perfectly legitimate not to have a single primary constructor. For example,when extending Exception, I often provide 3 constructors, one taking just a String message, one taking a Throwable cause and the other taking both. Each of these constructors calls super directly.

I struggled a lot to find the answer.

You don't really need to do anything with body size. All you need to remove the inline style from the map code:

<iframe width="425" height="350" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="https://maps.google.co.uk/maps?f=q&amp;source=s_q&amp;hl=en&amp;geocode=&amp;q=new+york&amp;aq=&amp;sll=53.546224,-2.106543&amp;sspn=0.02453,0.084543&amp;ie=UTF8&amp;hq=&amp;hnear=New+York,+United+States&amp;t=m&amp;z=10&amp;iwloc=A&amp;output=embed"></iframe><br /><small><a href="https://maps.google.co.uk/maps?f=q&amp;source=embed&amp;hl=en&amp;geocode=&amp;q=new+york&amp;aq=&amp;sll=53.546224,-2.106543&amp;sspn=0.02453,0.084543&amp;ie=UTF8&amp;hq=&amp;hnear=New+York,+United+States&amp;t=m&amp;z=10&amp;iwloc=A" style="color:#0000FF;text-align:left">View Larger Map</a></small>

remove all the inline style and add class or ID and then style it the way you like.

Since v-ref is no longer a directive, but a special attribute, it can also be dynamically defined. This is especially useful in combination with v-for.

For example:

<ul>
    <li v-for="(item, key) in items" v-on:click="play(item,$event)">
        <a v-bind:ref="'key' + item.id" v-bind:href="item.url">
            <!-- content -->
        </a>
    </li>
</ul>

and in Vue component you can use

var recordingModel = new Vue({
  el:'#rec-container',
  data:{
    items:[]
  },

  methods:{
    play:function(key,e){
      // it contains the bound reference
      console.log(this.$refs['item'+key]);
    }
  }
});

Calendar cal = Calendar.getInstance(desired date);
cal.setTimeInMillis(System.currentTimeMillis());
int dayOfWeek = cal.get(Calendar.DAY_OF_WEEK);

Get the day value by providing the current time stamp.

This was my solution, it returns true when the values don't overlap:

X START 1 Y END 1

A START 2 B END 2

TEST1: (X <= A || X >= B)
        &&
TEST2: (Y >= B || Y <= A) 
        && 
TEST3: (X >= B || Y <= A)


X-------------Y
    A-----B

TEST1:  TRUE
TEST2:  TRUE
TEST3:  FALSE
RESULT: FALSE

---------------------------------------

X---Y
      A---B

TEST1:  TRUE
TEST2:  TRUE
TEST3:  TRUE
RESULT: TRUE

---------------------------------------

      X---Y
A---B

TEST1:  TRUE
TEST2:  TRUE
TEST3:  TRUE
RESULT: TRUE

---------------------------------------

     X----Y
A---------------B

TEST1:  FALSE
TEST2:  FALSE
TEST3:  FALSE
RESULT: FALSE

I just used:

$('#source').prependTo('#destination');

Which I grabbed from here.

You could git fetch origin to update the remote branch in your repository to point to the latest version. For a diff against the remote:

git diff origin/master

Yes, you can use caret notation as well.

If you want to accept the remote changes:

git merge origin/master

CSS Grid layout

Like tables, grid layout enables an author to align elements into columns and rows.
https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Grid_Layout

To change the column sizes, take a look at the grid-template-columns property.

dl {_x000D_
  display: grid;_x000D_
  grid-template-columns: max-content auto;_x000D_
}_x000D_
_x000D_
dt {_x000D_
  grid-column-start: 1;_x000D_
}_x000D_
_x000D_
dd {_x000D_
  grid-column-start: 2;_x000D_
}

<dl>_x000D_
  <dt>Mercury</dt>_x000D_
  <dd>Mercury (0.4 AU from the Sun) is the closest planet to the Sun and the smallest planet.</dd>_x000D_
  <dt>Venus</dt>_x000D_
  <dd>Venus (0.7 AU) is close in size to Earth, (0.815 Earth masses) and like Earth, has a thick silicate mantle around an iron core.</dd>_x000D_

No, you are getting into the realm of Context Free Grammars at that point.

Below is the link which guide in parsing JSON string in android.

http://www.ibm.com/developerworks/xml/library/x-andbene1/?S_TACT=105AGY82&S_CMP=MAVE

Also according to your json string code snippet must be something like this:-

JSONObject mainObject = new JSONObject(yourstring);

JSONObject universityObject = mainObject.getJSONObject("university");
JSONString name = universityObject.getString("name");  
JSONString url = universityObject.getString("url");

Following is the API reference for JSOnObject: https://developer.android.com/reference/org/json/JSONObject.html#getString(java.lang.String)

Same for other object.

check it

const mq = window.matchMedia( "(min-width: 500px)" );

if (mq.matches) {
  // window width is at least 500px
} else {
  // window width is less than 500px
}

https://developer.mozilla.org/en-US/docs/Web/API/Window/matchMedia

Those settings (core.whitespace and apply.whitespace) are not there to remove trailing whitespace but to:

• core.whitespace: detect them, and raise errors
• apply.whitespace: and strip them, but only during patch, not "always automatically"

I believe the git hook pre-commit would do a better job for that (includes removing trailing whitespace)

Note that at any given time you can choose to not run the pre-commit hook:

• temporarily: git commit --no-verify .
• permanently: cd .git/hooks/ ; chmod -x pre-commit

Warning: by default, a pre-commit script (like this one), has not a "remove trailing" feature", but a "warning" feature like:

if (/\s$/) {
    bad_line("trailing whitespace", $_);
}

You could however build a better pre-commit hook, especially when you consider that:

Committing in Git with only some changes added to the staging area still results in an “atomic” revision that may never have existed as a working copy and may not work.

For instance, oldman proposes in another answer a pre-commit hook which detects and remove whitespace.
Since that hook get the file name of each file, I would recommend to be careful for certain type of files: you don't want to remove trailing whitespace in .md (markdown) files!

Methods suggest something has to happen to return the value, properties suggest that the value is already there. This is a rule of thumb, sometimes you might want a property that does a little work (i.e. Count), but generally it's a useful way to decide.

If you have python version 3.6 or higher you can use f strings

>>> string = "John"
>>> f"{string:<15}"
'John           '

Or if you'd like it to the left

>>> f"{string:>15}"
'          John'

Centered

>>> f"{string:^15}"
'     John      '

First, you'll need to add session_start() at the top of any page that you wish to use SESSION variables on.

Also, you should check to make sure the variable is set first before using it:

if(isset($_SESSION['SESS_fname'])){
    echo $_SESSION['SESS_fname'];
}

Or, simply:

echo (isset($_SESSION['SESS_fname']) ? $_SESSION['SESS_fname'] : "Visitor");

It's probably because you are directly or indirectly through a library call accessing a NULL pointer. In this particular case, it looks like you've jumped to a NULL address, which is a b bit hairier.

In my experience, the easiest way to track these down are to run it with a debugger, and dump a stack trace.

Alternatively, you can do it "by hand" and add lots of logging until you can track down exactly which function (and possibly LOC) this violation occurred in.

Take a look at Stack Tracer, which might help you improve your debugging.

It's as easy as:

delete object.keyname;

or

delete object["keyname"];

I got the answer.

Here is the code:

SELECT * FROM table
WHERE STR_TO_DATE(column, '%d/%m/%Y')
  BETWEEN STR_TO_DATE('29/01/15', '%d/%m/%Y')
    AND STR_TO_DATE('07/10/15', '%d/%m/%Y')

To distinguish them intuitively

l1 = ['a', 'b', 'c']
l2 = ['d', 'e', 'f']
l1.append(l2)
l1
['a', 'b', 'c', ['d', 'e', 'f']]

It's like l1 reproduce a body inside her body(nested).

# Reset l1 = ['a', 'b', 'c']
l1.extend(l2)
l1
['a', 'b', 'c', 'd', 'e', 'f']

It's like that two separated individuals get married and construct an united family.

Besides I make an exhaustive cheatsheet of all list's methods for your reference.

                'Sort': {'reverse', 'sort'},
                'Search': {'count', 'index'},
                'Copy': {'copy'},
                }

As far as I know, you can't ask apt for what their current sources are. However, you can do what you want using shell tools.

Getting a list of repositories:

grep -h ^deb /etc/apt/sources.list /etc/apt/sources.list.d/* >> current.repos.list

Applying the list:

apt-add-repository << current.repos.list

Regarding getting the repository from a package (installed or available), this will do the trick:

apt-cache policy package_name | grep -m1 http | awk '{ print $2 " " $3 }'

However, that will show you the repository of the latest version available of that package, and you may have more repositories for the same package with older versions. Remove all the grep/awk stuff if you want to see the full list.

If you wanna go the modern way, you can do this:

const selectedOpts = [...field.options].filter((x) => x.selected);

The ... operator maps iterable (HTMLOptionsCollection) to the array.

If you're just interested in the values, you can add a map() call:

const selectedValues = [...field.options]
                     .filter((x) => x.selected)
                     .map((x)=>x.value);

Introduction

The ServletContext#getRealPath() is intented to convert a web content path (the path in the expanded WAR folder structure on the server's disk file system) to an absolute disk file system path.

The "/" represents the web content root. I.e. it represents the web folder as in the below project structure:

YourWebProject
 |-- src
 |    :
 |
 |-- web
 |    |-- META-INF
 |    |    `-- MANIFEST.MF
 |    |-- WEB-INF
 |    |    `-- web.xml
 |    |-- index.jsp
 |    `-- login.jsp
 :    

So, passing the "/" to getRealPath() would return you the absolute disk file system path of the /web folder of the expanded WAR file of the project. Something like /path/to/server/work/folder/some.war/ which you should be able to further use in File or FileInputStream.

Note that most starters don't seem to see/realize that you can actually pass the whole web content path to it and that they often use

String absolutePathToIndexJSP = servletContext.getRealPath("/") + "index.jsp"; // Wrong!

or even

String absolutePathToIndexJSP = servletContext.getRealPath("") + "index.jsp"; // Wronger!

instead of

String absolutePathToIndexJSP = servletContext.getRealPath("/index.jsp"); // Right!

Don't ever write files in there

Also note that even though you can write new files into it using FileOutputStream, all changes (e.g. new files or edited files) will get lost whenever the WAR is redeployed; with the simple reason that all those changes are not contained in the original WAR file. So all starters who are attempting to save uploaded files in there are doing it wrong.

Moreover, getRealPath() will always return null or a completely unexpected path when the server isn't configured to expand the WAR file into the disk file system, but instead into e.g. memory as a virtual file system.

getRealPath() is unportable; you'd better never use it

Use getRealPath() carefully. There are actually no sensible real world use cases for it. Based on my 20 years of Java EE experience, there has always been another way which is much better and more portable than getRealPath().

If all you actually need is to get an InputStream of the web resource, better use ServletContext#getResourceAsStream() instead, this will work regardless of the way how the WAR is expanded. So, if you for example want an InputStream of index.jsp, then do not do:

InputStream input = new FileInputStream(servletContext.getRealPath("/index.jsp")); // Wrong!

But instead do:

InputStream input = servletContext.getResourceAsStream("/index.jsp"); // Right!

Or if you intend to obtain a list of all available web resource paths, use ServletContext#getResourcePaths() instead.

Set<String> resourcePaths = servletContext.getResourcePaths("/");

You can obtain an individual resource as URL via ServletContext#getResource(). This will return null when the resource does not exist.

URL resource = servletContext.getResource(path);

Or if you intend to save an uploaded file, or create a temporary file, then see the below "See also" links.

See also:

• getResourceAsStream() vs FileInputStream
• Recommended way to save uploaded files in a servlet application

It says

In all browsers, the load, scroll, and error events (e.g., on an <img> element) do not bubble. In Internet Explorer 8 and lower, the paste and reset events do not bubble. Such events are not supported for use with delegation, but they can be used when the event handler is directly attached to the element generating the event.

If you want to do something when a new input box is added then you can simply write the code after appending it.

$('#add').click(function(){
        $('body').append(x);
        // Your code can be here
    });

And if you want the same code execute when the first input box within the document is loaded then you can write a function and call it in both places i.e. $('#add').click and document's ready event

{ "date" : "1000000" } in your Mongo doc seems suspect. Since it's a number, it should be { date : 1000000 }

It's probably a type mismatch. Try post.findOne({date: "1000000"}, callback) and if that works, you have a typing issue.

You need to do this:

OleDbConnection connection = new OleDbConnection(
    "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Inventar.accdb");
DataSet DS = new DataSet();
connection.Open();

string query = 
    @"SELECT tbl_Computer.*,  tbl_Besitzer.*
    FROM tbl_Computer 
    INNER JOIN tbl_Besitzer ON tbl_Computer.FK_Benutzer = tbl_Besitzer.ID 
    WHERE (((tbl_Besitzer.Vorname)='ma'))";
OleDbDataAdapter DBAdapter = new OleDbDataAdapter();
DBAdapter.SelectCommand = new OleDbCommand(query, connection); 
DBAdapter.Fill(DS);

By the way, what is this DataSet1? This should be "DataSet".

Based on post by toster-cx and other interesting posts on this page, I got insight on how to configure and solve my problem.

ArrayList get(int index) method is used for fetching an element from the list. We need to specify the index while calling get method and it returns the value present at the specified index.

public Element get(int index)

Example : In below example we are getting few elements of an arraylist by using get method.

package beginnersbook.com;
import java.util.ArrayList;
public class GetMethodExample {
   public static void main(String[] args) {
       ArrayList<String> al = new ArrayList<String>();
       al.add("pen");
       al.add("pencil");
       al.add("ink");
       al.add("notebook");
       al.add("book");
       al.add("books");
       al.add("paper");
       al.add("white board");

       System.out.println("First element of the ArrayList: "+al.get(0));
       System.out.println("Third element of the ArrayList: "+al.get(2));
       System.out.println("Sixth element of the ArrayList: "+al.get(5));
       System.out.println("Fourth element of the ArrayList: "+al.get(3));
   }
}

Output:

First element of the ArrayList: pen
Third element of the ArrayList: ink
Sixth element of the ArrayList: books
Fourth element of the ArrayList: notebook

Looks file you use the .mkdirs() method on a File object: http://www.roseindia.net/java/beginners/java-create-directory.shtml

// Create a directory; all non-existent ancestor directories are
// automatically created
success = (new File("../potentially/long/pathname/without/all/dirs")).mkdirs();
if (!success) {
    // Directory creation failed
}

LINQ Generic Way:

    public static Dictionary<int, string> ToList<T>() where T : struct =>
        ((IEnumerable<T>)Enum.GetValues(typeof(T))).ToDictionary(value => Convert.ToInt32(value), value => value.ToString());

Usage:

        var enums = ToList<Enum>();

==> MyGcmListenerService.java Use BadgeUtils class when notification comes.

public class MyGcmListenerService extends GcmListenerService { 

    private static final String TAG = "MyGcmListenerService"; 
    @Override
    public void onMessageReceived(String from, Bundle data) {

            String message = data.getString("Msg");
            String Type = data.getString("Type");

            intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
                    PendingIntent.FLAG_ONE_SHOT);

            Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

            NotificationCompat.BigTextStyle bigTextStyle= new NotificationCompat.BigTextStyle();

            bigTextStyle .setBigContentTitle(getString(R.string.app_name))
                    .bigText(message);
            NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                    .setSmallIcon(getNotificationIcon())

                    .setContentText(message)
                    .setStyle(bigTextStyle) 
                    .setAutoCancel(true)

                    .setContentIntent(pendingIntent);

            int color = getResources().getColor(R.color.appColor);
            notificationBuilder.setColor(color);
            NotificationManager notificationManager =
                    (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);


            int unOpenCount=AppUtill.getPreferenceInt("NOTICOUNT",this);
            unOpenCount=unOpenCount+1;

            AppUtill.savePreferenceLong("NOTICOUNT",unOpenCount,this);  
            notificationManager.notify(unOpenCount /* ID of notification */, notificationBuilder.build()); 

// This is for bladge on home icon          
        BadgeUtils.setBadge(MyGcmListenerService.this,(int)unOpenCount);

    }


    private int getNotificationIcon() {
        boolean useWhiteIcon = (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP);
        return useWhiteIcon ? R.drawable.notification_small_icon : R.drawable.icon_launcher;
    }
}

And clear notification from preference and also with badge count

 public class SplashActivity extends AppCompatActivity {

                    AppUtill.savePreferenceLong("NOTICOUNT",0,this);
                    BadgeUtils.clearBadge(this);
            }
    }

Use fabs() instead of abs(), it's the same but for floats instead of integers.

First of all, make 'E' in enum, 'e' as a lower case.

Second, drop type name 'Days' in 'Days.Saturday'.

Third ...buy yourself a good C++ book.

In my case I am using jQuery .load() to update DIVs in a SPA (single page [web] app) .

Being new to working with $(window).on('hashchange', ..) event listener , this one proved challenging and took a bit to hack on. Thanks to reading a lot of answers and trying different variations, finally figured out how to make it work in the following manner. Far as I can tell, it is looking stable so far.

In summary - there is the variable globalCurrentHash that should be set each time you load a view.

Then when $(window).on('hashchange', ..) event listener runs, it checks the following:

• If location.hash has the same value, it means Going Forward
• If location.hash has different value, it means Going Back

I realize using global vars isn't the most elegant solution, but doing things OO in JS seems tricky to me so far. Suggestions for improvement/refinement certainly appreciated

Set Up:

1. Define a global var :

    var globalCurrentHash = null;

2. When calling .load() to update the DIV, update the global var as well :

   function loadMenuSelection(hrefVal) {
     $('#layout_main').load(nextView);
     globalCurrentHash = hrefVal;
   }
   

3. On page ready, set up the listener to check the global var to see if Back Button is being pressed:

   $(document).ready(function(){
     $(window).on('hashchange', function(){
         console.log( 'location.hash: ' + location.hash );
         console.log( 'globalCurrentHash: ' + globalCurrentHash );
   
         if (location.hash == globalCurrentHash) {
             console.log( 'Going fwd' );
         }
         else {
   
             console.log( 'Going Back' );
             loadMenuSelection(location.hash);
         }
       });
   
   });
   

The problem with SQL injection is, that a user input is used as part of the SQL statement. By using prepared statements you can force the user input to be handled as the content of a parameter (and not as a part of the SQL command).

But if you don't use the user input as a parameter for your prepared statement but instead build your SQL command by joining strings together, you are still vulnerable to SQL injections even when using prepared statements.

In addition:

Following the L I N K of the A N S W E R here.

Here is a little example addressing the following point:

x[i, j] vs x[[i, j]]

df1   <- data.frame(a = 1:3)
df1$b <- list(4:5, 6:7, 8:9)

df1[[1,2]]
df1[1,2]

str(df1[[1,2]])
str(df1[1,2])

You have to initialise the object (create the object itself) in order to be able to call its methods otherwise you would get a NullPointerException.

WordList words = new WordList();

One reason: the literal 0 has a bad tendency to acquire the type int, e.g. in perfect argument forwarding or more in general as argument with templated type.

Another reason: readability and clarity of code.

I am always used DateDiff(day,date1,date2) to compare two date.

Checkout following example. Just copy that and run in Ms sql server. Also, try with change date by 31 dec to 30 dec and check result

BEGIN

declare @firstDate datetime
declare @secondDate datetime


declare @chkDay int

set @firstDate ='2010-12-31 15:13:48.593'
set @secondDate ='2010-12-31 00:00:00.000'

set @chkDay=Datediff(day,@firstDate ,@secondDate )

if @chkDay=0
    Begin
        Print 'Date is Same'
    end
else
    Begin
        Print 'Date is not Same'
    end
End

There's are ambiguities in the question.

What is your input string? Is it the entire file? Or is it 1 line at a time? Some of the answers are assuming the latter. I want to answer the former.

What would you like to return from your regular expression? The fact that you want a true / false on whether a match was made? Or do you want to extract the entire line whose start begins with CTR? I'll answer you only want a true / false match.

To do this, we just need to determine if the CTR occurs at either the start of a file, or immediately following a new line.

/(?:^|\n)CTR/

It is not an import problem. You simply call .dropDuplicates() on a wrong object. While class of sqlContext.createDataFrame(rdd1, ...) is pyspark.sql.dataframe.DataFrame, after you apply .collect() it is a plain Python list, and lists don't provide dropDuplicates method. What you want is something like this:

 (df1 = sqlContext
     .createDataFrame(rdd1, ['column1', 'column2', 'column3', 'column4'])
     .dropDuplicates())

 df1.collect()

Unfortunately it seems to be a issue with MySql usage of "NOT IN" clause, the screen-shoot below shows the sub-query option returning wrong results:

Try

//*[text()='qwerty'] because . is your current element

git checkout -b your-new-branch

git add <files>

git commit -m <message>

First, checkout your new branch. Then add all the files you want to commit to staging. Lastly, commit all the files you just added. You might want to do a git push origin your-new-branch afterward so your changes show up on the remote.

MySQL 5.x specification for decimal datatype is: DECIMAL[(M[,D])] [UNSIGNED] [ZEROFILL]. The answer above is wrong (now corrected) in saying that unsigned decimals are not possible.

To define a field allowing only unsigned decimals, with a total length of 6 digits, 4 of which are decimals, you would use: DECIMAL (6,4) UNSIGNED.

You can likewise create unsigned (ie. not negative) FLOAT and DOUBLE datatypes.

Update on MySQL 8.0.17+, as in MySQL 8 Manual: 11.1.1 Numeric Data Type Syntax:

"Numeric data types that permit the UNSIGNED attribute also permit SIGNED. However, these data types are signed by default, so the SIGNED attribute has no effect.*

As of MySQL 8.0.17, the UNSIGNED attribute is deprecated for columns of type FLOAT, DOUBLE, and DECIMAL (and any synonyms); you should expect support for it to be removed in a future version of MySQL. Consider using a simple CHECK constraint instead for such columns.

You need to set the thumbnail class to position relative then the post-content to absolute.

Check this fiddle

.post-content {
    top:0;
    left:0;
    position: absolute;
}

.thumbnail{
    position:relative;

}

Giving it top and left 0 will make it appear in the top left corner.

To expand on @Bobby's asnwer above. You can edit your .csproj to use IL-Repack to automatically package all files into a single assembly when you build.

1. Install the nuget ILRepack.MSBuild.Task package with Install-Package ILRepack.MSBuild.Task
2. Edit the AfterBuild section of your .csproj

Here is a simple sample that merges ExampleAssemblyToMerge.dll into your project output.

<!-- ILRepack -->
<Target Name="AfterBuild" Condition="'$(Configuration)' == 'Release'">

   <ItemGroup>
    <InputAssemblies Include="$(OutputPath)\$(AssemblyName).exe" />
    <InputAssemblies Include="$(OutputPath)\ExampleAssemblyToMerge.dll" />
   </ItemGroup>

   <ILRepack 
    Parallel="true"
    Internalize="true"
    InputAssemblies="@(InputAssemblies)"
    TargetKind="Exe"
    OutputFile="$(OutputPath)\$(AssemblyName).exe"
   />
</Target>

Beware: There are also cells which are seemingly blank, but are not truly empty but containg "" or something that is called NULL in other languages. As an example, when a formula results in "" or such result is copied to a cell, the formula

ISBLANK(A1) 

returns FALSE. That means the cell is not truly empty.

The way to go there is to use enter code here

COUNTBLANK(A1)

Which finds both truly empty cells and those containing "". See also this very good answer here

I couldn't figure out how to pass args and also the :environment until I worked this out:

namespace :db do
  desc 'Export product data'
  task :export, [:file_token, :file_path] => :environment do |t, args|
    args.with_defaults(:file_token => "products", :file_path => "./lib/data/")

       #do stuff [...]

  end
end

And then I call like this:

rake db:export['foo, /tmp/']

To search the whole computer:

gdr -PSProvider 'FileSystem' | %{ ls -r $_.root} 2>$null | where { $_.name -eq "httpd.exe" }

Here's something which might be useful. Selecting the entire column based on a row containing data, in this case i am using 5th row:

Dim lColumn As Long

lColumn = ActiveSheet.Cells(5, Columns.Count).End(xlToLeft).Column
MsgBox ("The last used column is: " & lColumn)

If you are not root user then, use following commands:

There are two ways to do it -

1.

sudo vi path_to_file/file_name

Press Esc and then type below respectively

:wq //save and exit
:q! //exit without saving

2. sudo nano path_to_file/file_name

When using nano: after you finish editing press ctrl+x then it will ask save Y/N.
If you want to save press Y, if not press N. And press enter to exit the editor.

Based on Laravel docs for raw queries I was able to get count for a select field to work with this code in the product model.

public function scopeShowProductCount($query)
{
    $query->select(DB::raw('DISTINCT pid, COUNT(*) AS count_pid'))
          ->groupBy('pid')
          ->orderBy('count_pid', 'desc');
}

This facade worked to get the same result in the controller:

$products = DB::table('products')->select(DB::raw('DISTINCT pid, COUNT(*) AS count_pid'))->groupBy('pid')->orderBy('count_pid', 'desc')->get();

The resulting dump for both queries was as follows:

#attributes: array:2 [
  "pid" => "1271"
  "count_pid" => 19
],
#attributes: array:2 [
  "pid" => "1273"
  "count_pid" => 12
],
#attributes: array:2 [
  "pid" => "1275"
  "count_pid" => 7
]

If your class is non-activity class, and creating an instance of it from the activiy, you can pass an instance of context via constructor of the later as follows:

class YourNonActivityClass{

// variable to hold context
private Context context;

//save the context recievied via constructor in a local variable

public YourNonActivityClass(Context context){
    this.context=context;
}

}

You can create instance of this class from the activity as follows:

new YourNonActivityClass(this);

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'
 }

If there is any chance that you will need to search for empty strings,

    a['Names'].str.contains('') 

will NOT work, as it will always return True.

Instead, use

    if '' in a["Names"].values

to accurately reflect whether or not a string is in a Series, including the edge case of searching for an empty string.

Kotlin for XML

app:cardBackgroundColor="@android:color/red"

code

cardName.setCardBackgroundColor(ContextCompat.getColor(this, R.color.colorGray));

add KexAlgorithms diffie-hellman-group1-sha1,diffie-hellman-group-exchange-sha??1 to your sshd_config on the server.

This worked, but make sure you restart sshd: sudo service sshd restart

I'd say use <em> to emphasize inline elements. Use a class for block elements like blocks of text. CSS or not, the text still has to be tagged. Whether its for semantics or for visual aid, I'm assuming you'd be using it for something meaningful...

If you're emphasizing text for ANY reason, you could use <em>, or a class that italicizes your text.

It's OK to break the rules sometimes!

Window.Show will show the window, and continue execution -- it's a non-blocking call.

Window.ShowDialog will block the calling thread (kinda ^[1]), and show the dialog. It will also block interaction with the parent/owning window. When the dialog is dismissed (for whatever reason), ShowDialog will return to the caller, and will allow you to access DialogResult (if you want it).

^[1] It will keep the dispatcher pumping by pushing a dispatcher frame onto the WPF dispatcher. This will cause the message pump to keep pumping.

You can code like two input box inside one div

<div class="input-group">
            <span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span>
            <input style="width:50% " class="form-control " placeholder="first name"  name="firstname" type="text" />
            <input style="width:50% " class="form-control " placeholder="lastname"  name="lastname" type="text" />
        </div>

Here multiple columns need to be converted. So, one approach i used is ..

for col_name in df.columns:
    if(df[col_name].dtype == 'object'):
        df[col_name]= df[col_name].astype('category')
        df[col_name] = df[col_name].cat.codes

This converts all string / object type columns to categorical. Then applies codes to each type of category.

Give a try to return bootstrap alert message, this worked for me

return Content("<div class='alert alert-success'><a class='close' data-dismiss='alert'>
&times;</a><strong style='width:12px'>Thanks!</strong> updated successfully</div>");

Note: Don't forget to add bootstrap css and js in your view page

hope helps someone.

just like in C and C++, the boolean or operator is ||

if (ActionsLogWriter.Close || ErrorDumpWriter.Close == true)
{
    // Do stuff here
}

Inspired by Nelson's comment I made this.

Workaround for javascript Same-origin policy with regards to using.ScrollTo( ) on document originating on an external domain.

Very simple workaround for this involves creating a dummy HTML page that hosts the external website within it, then calling .ScrollTo(x,y) on that page once it's loaded. Then the only thing you need to do is have a frame or an iframe bring up this website.

There are a lot of other ways to do it, this is by far the most simplified way to do it.

*note the height must be large to accommodate the scroll bars maximum value.

--home.html

<html>
<head>
<title>Home</title>
</head>

<frameset rows="*,170">
<frame src=body.htm noresize=yes frameborder=0 marginheight=0 marginwidth=0 scrolling="no">
<frame src="weather.htm" noresize=yes frameborder=0 marginheight=0 marginwidth=0 scrolling="no">
</frameset>
</html>

--weather.html

<html>
<head>
<title>Weather</title>
</head>

<body onLoad="window.scrollTo(0,170)">

<iframe id="iframe" src="http://forecast.weather.gov/MapClick.php?CityName=Las+Vegas&state=NV&site=VEF&textField1=36.175&textField2=-115.136&e=0" height=1000 width=100% frameborder=0 marginheight=0 marginwidth=0 scrolling=no>

That functionality is already built into Notepad++. From the "Edit" menu, select "EOL Conversion" -> "UNIX/OSX Format".

You can also set the default EOL in notepad++ via "Settings" -> "Preferences" -> "New Document/Default Directory" then select "Unix/OSX" under the Format box.

$var = $f->filter($_GET['params']);

There are two common approaches for this: either reserve a specific color as being "transparent," in which case you cannot use that color in images without it appearing transparent, or define a fourth channel alongside red, green, and blue called "alpha" which indicates translucency/transparency.

I had the same problem when working in Angular 5. In order to make it work directly without writing a polyfill yourself, just add the following line to polyfills.ts file:

import "core-js/es7/array"

Also, tsconfig.json lib section might be relevant:

"lib": [
  "es2017",
  "dom"
],

tryCatch has a slightly complex syntax structure. However, once we understand the 4 parts which constitute a complete tryCatch call as shown below, it becomes easy to remember:

expr: [Required] R code(s) to be evaluated

error : [Optional] What should run if an error occured while evaluating the codes in expr

warning : [Optional] What should run if a warning occured while evaluating the codes in expr

finally : [Optional] What should run just before quitting the tryCatch call, irrespective of if expr ran successfully, with an error, or with a warning

tryCatch(
    expr = {
        # Your code...
        # goes here...
        # ...
    },
    error = function(e){ 
        # (Optional)
        # Do this if an error is caught...
    },
    warning = function(w){
        # (Optional)
        # Do this if an warning is caught...
    },
    finally = {
        # (Optional)
        # Do this at the end before quitting the tryCatch structure...
    }
)

Thus, a toy example, to calculate the log of a value might look like:

log_calculator <- function(x){
    tryCatch(
        expr = {
            message(log(x))
            message("Successfully executed the log(x) call.")
        },
        error = function(e){
            message('Caught an error!')
            print(e)
        },
        warning = function(w){
            message('Caught an warning!')
            print(w)
        },
        finally = {
            message('All done, quitting.')
        }
    )    
}

Now, running three cases:

A valid case

log_calculator(10)
# 2.30258509299405
# Successfully executed the log(x) call.
# All done, quitting.

A "warning" case

log_calculator(-10)
# Caught an warning!
# <simpleWarning in log(x): NaNs produced>
# All done, quitting.

An "error" case

log_calculator("log_me")
# Caught an error!
# <simpleError in log(x): non-numeric argument to mathematical function>
# All done, quitting.

I've written about some useful use-cases which I use regularly. Find more details here: https://rsangole.netlify.com/post/try-catch/

Hope this is helpful.

As I see it, there are three ways to go with this,

1) The easy way.

double rand_easy(void)
{       return (double) rand() / (RAND_MAX + 1.0);
}

2) The safe way (standard conforming).

double rand_safe(void)
{
        double limit = pow(2.0, DBL_MANT_DIG);
        double denom = RAND_MAX + 1.0;
        double denom_to_k = 1.0;
        double numer = 0.0;

        for ( ; denom_to_k < limit; denom_to_k *= denom )
           numer += rand() * denom_to_k;

        double result = numer / denom_to_k;
        if (result == 1.0)
           result -= DBL_EPSILON/2;
        assert(result != 1.0);
        return result;
}

3) The custom way.

By eliminating rand() we no longer have to worry about the idiosyncrasies of any particular version, which gives us more leeway in our own implementation.

Note: Period of the generator used here is ≅ 1.8e+19.

#define RANDMAX (-1ULL)
uint64_t custom_lcg(uint_fast64_t* next)
{       return *next = *next * 2862933555777941757ULL + 3037000493ULL;
}

uint_fast64_t internal_next;
void seed_fast(uint64_t seed)
{       internal_next = seed;
}

double rand_fast(void)
{
#define SHR_BIT (64 - (DBL_MANT_DIG-1))
        union {
            double f; uint64_t i;
        } u;
        u.f = 1.0;
        u.i = u.i | (custom_lcg(&internal_next) >> SHR_BIT);
        return u.f - 1.0;
}

Whatever the choice, functionality may be extended as follows,

double rand_dist(double min, double max)
{       return rand_fast() * (max - min) + min;
}

double rand_open(void)
{       return rand_dist(DBL_EPSILON, 1.0);
}

double rand_closed(void)
{       return rand_dist(0.0, 1.0 + DBL_EPSILON);
}

Final notes: The fast version - while written in C - may be adapted for use in C++ to be used as a replacement for std::generate_canonical, and will work for any generator emitting values with sufficient significant bits.

Most 64 bit generators take advantage of their full width, so this can likely be used without modification (shift adjustment). e.g. this works as-is with the std::mt19937_64 engine.

Does the column allow null?

Seems to work. Just tested with phpMyAdmin, the column is of type int that allows nulls:

INSERT INTO `database`.`table` (`column`) VALUES (NULL);

This will help....

function get_time($date,$nosuffix=''){
    $datetime = new DateTime($date);
    $interval = date_create('now')->diff( $datetime );
    if(empty($nosuffix))$suffix = ( $interval->invert ? ' ago' : '' );
    else $suffix='';
    //return $interval->y;
    if($interval->y >=1)        {$count = date(VDATE, strtotime($date)); $text = '';}
    elseif($interval->m >=1)    {$count = date('M d', strtotime($date)); $text = '';}
    elseif($interval->d >=1)    {$count = $interval->d; $text = 'day';} 
    elseif($interval->h >=1)    {$count = $interval->h; $text = 'hour';}
    elseif($interval->i >=1)    {$count = $interval->i; $text = 'minute';}
    elseif($interval->s ==0)    {$count = 'Just Now'; $text = '';}
    else                        {$count = $interval->s; $text = 'second';}
    if(empty($text)) return '<i class="fa fa-clock-o"></i> '.$count;
    return '<i class="fa fa-clock-o"></i> '.$count.(($count ==1)?(" $text"):(" ${text}s")).' '.$suffix;     
}

You can declare a function to enable/disable all of the form control:

  toggleDisableFormControl(value: Boolean, exclude = []) {
    const state = value ? 'disable' : 'enable';
    Object.keys(this.profileForm.controls).forEach((controlName) => {
      if (!exclude.includes(controlName))
        this.profileForm.controls[controlName][state]();
    });
  }

and use it like this

this.toggleDisableFormControl(true, ['email']);
// disbale all field but email

Set sh1 = Worksheets(filenum(lngPosition)).Activate

You are getting Subscript out of range error error becuase it cannot find that Worksheet.

Also please... please... please do not use .Select/.Activate/Selection/ActiveCell You might want to see How to Avoid using Select in Excel VBA Macros.

Although the terms URI and URL are strictly defined, many use the terms for other things than they are defined for.

Let’s take Apache for example. If http://example.com/foo is requested from an Apache server, you’ll have the following environment variables set:

• REDIRECT_URL: /foo
• REQUEST_URI: /foo

With mod_rewrite enabled, you will also have these variables:

• REDIRECT_SCRIPT_URL: /foo
• REDIRECT_SCRIPT_URI: http://example.com/foo
• SCRIPT_URL: /foo
• SCRIPT_URI: http://example.com/foo

This might be the reason for some of the confusion.

Answer provided by @Prashanth is correct, but there is even easier way of doing the same. Basically instead of injecting the $filter dependency and using awkward syntax of invoking it ($filter('filtername')(arg1,arg2);) one can inject dependency being: filter name plus the Filter suffix.

Taking example from the question one could write:

function myCtrl($scope, filter1Filter) { 
  filter1Filter(input, arg1);
}

It should be noted that you must append Filter to the filter name, no matter what naming convention you're using: foo is referenced by calling fooFilter
fooFilter is referenced by calling fooFilterFilter

HostListener should be the proper way to bind event into your component:

@Component({
  selector: 'your-element'
})

export class YourElement {
  @HostListener('click', ['$event']) onClick(event) {
     console.log('component is clicked');
     console.log(event);
  }
}

When your browser redirects the user to Google's oAuth page, are you passing as a parameter the redirect URI you want Google's server to return to with the token response? Setting a redirect URI in the console is not a way of telling Google where to go when a login attempt comes in, but rather it's a way of telling Google what the allowed redirect URIs are (so if someone else writes a web app with your client ID but a different redirect URI it will be disallowed); your web app should, when someone clicks the "login" button, send the browser to:

https://accounts.google.com/o/oauth2/auth?client_id=XXXXX&redirect_uri=http://localhost:8080/WEBAPP/youtube-callback.html&response_type=code&scope=https://www.googleapis.com/auth/youtube.upload

(the callback URI passed as a parameter must be url-encoded, btw).

When Google's server gets authorization from the user, then, it'll redirect the browser to whatever you sent in as the redirect_uri. It'll include in that request the token as a parameter, so your callback page can then validate the token, get an access token, and move on to the other parts of your app.

If you visit:

http://code.google.com/p/google-api-java-client/wiki/OAuth2#Authorization_Code_Flow

You can see better samples of the java client there, demonstrating that you have to override the getRedirectUri method to specify your callback path so the default isn't used.

The redirect URIs are in the client_secrets.json file for multiple reasons ... one big one is so that the oAuth flow can verify that the redirect your app specifies matches what your app allows.

If you visit https://developers.google.com/api-client-library/java/apis/youtube/v3 You can generate a sample application for yourself that's based directly off your app in the console, in which (again) the getRedirectUri method is overwritten to use your specific callbacks.

I was having the same problem. Don't know if you've solved this or not, but what I was really trying to do was access a network share with AD credentials. WNetAddConnection2() is what you need to use in that case.

Here's a script to do this automatically

# Only allow key based logins
sed -n 'H;${x;s/\#PasswordAuthentication yes/PasswordAuthentication no/;p;}' /etc/ssh/sshd_config > tmp_sshd_config
cat tmp_sshd_config > /etc/ssh/sshd_config
rm tmp_sshd_config

Many of the answerers spotted the issue and already gave the solution.

I just want to suggest another solution, which is changing the Glogal variable value from within the tool Mysql Workbench. That is ofcourse IF you use Workbench running locally on server (or via SSH connection)

You just connect to your instance and go on menu:

Server -> Options File -> Networking -> max_allowed_packed

You set the desired value and then you need to restart MySql Service.

You might be using the enums incorrectly in the switch cases. In comparison with the above example by CoolBeans.. you might be doing the following:

switch(day) {
    case Day.MONDAY:
        // Something..
        break;
    case Day.FRIDAY:
        // Something friday
        break;
}

Make sure that you use the actual enum values instead of EnumType.EnumValue

Eclipse points out this mistake though..

working like a charm here for bootstrap 4>4.1.1

var myGroup = $('your-list');

myGroup.on('show.bs.collapse','.collapse', function() {
   myGroup.find('.collapse.show').collapse('hide');
});

In Angular use 'extends' to define the interface for an 'Array' of objects.

Using an indexer will give you an error as its not an Array interface so doesn't contain the properties and methods.

e.g

error TS2339: Property 'find' does not exist on type 'ISelectOptions2'.

// good    
export interface ISelectOptions1 extends Array<ISelectOption> {}

// bad
export interface ISelectOptions2 {
    [index: number]: ISelectOption;
}

interface ISelectOption {
    prop1: string;
    prop2?: boolean;
}

The accepted answer from Paul is great. I've made a small extension to this which is very useful if you have an multidimensional array like this (which is quite common):

Array
(
    [0] => Array
        (
            [a] => "a"
            [b] => "b"
        )

    [1] => Array
        (
            [a] => "a2"
            [b] => "b2"
        )

    [2] => Array
        (
            [a] => "a3"
            [b] => "b3"
        )

    [3] => Array
        (
            [a] => "a4"
            [b] => "b4"
        )

    [4] => Array
        (
            [a] => "a5"
            [b] => "b5"
        )

)

So I just took Paul's function from above:

/**
  * Formats a line (passed as a fields  array) as CSV and returns the CSV as a string.
  * Adapted from http://us3.php.net/manual/en/function.fputcsv.php#87120
  */
function arrayToCsv( array &$fields, $delimiter = ';', $enclosure = '"', $encloseAll = false, $nullToMysqlNull = false ) {
    $delimiter_esc = preg_quote($delimiter, '/');
    $enclosure_esc = preg_quote($enclosure, '/');

    $output = array();
    foreach ( $fields as $field ) {
        if ($field === null && $nullToMysqlNull) {
            $output[] = 'NULL';
            continue;
        }

        // Enclose fields containing $delimiter, $enclosure or whitespace
        if ( $encloseAll || preg_match( "/(?:${delimiter_esc}|${enclosure_esc}|\s)/", $field ) ) {
            $output[] = $enclosure . str_replace($enclosure, $enclosure . $enclosure, $field) . $enclosure;
        }
        else {
            $output[] = $field;
        }
    }

    return implode( $delimiter, $output );
}

And added this:

function a2c($array, $glue = "\n")
{
    $ret = [];
    foreach ($array as $item) {
        $ret[] = arrayToCsv($item);
    }
    return implode($glue, $ret);
}

So you can just call:

$csv = a2c($array);

If you want a special line ending you can use the optional parameter "glue" for this.

Algorithms in the Divide and Conquer paradigm are of complexity O(logn). One example here, calculate your own power function,

int power(int x, unsigned int y)
{
    int temp;
    if( y == 0)
        return 1;
    temp = power(x, y/2);
    if (y%2 == 0)
        return temp*temp;
    else
        return x*temp*temp;
}

from http://www.geeksforgeeks.org/write-a-c-program-to-calculate-powxn/

I have written a piece of code that puts the command line arguments in the format that gradle expects.

// this method creates a command line arguments
def setCommandLineArguments(commandLineArgs) {
    // remove spaces 
    def arguments = commandLineArgs.tokenize()

            // create a string that can be used by Eval 
            def cla = "["
            // go through the list to get each argument
            arguments.each {
                    cla += "'" + "${it}" + "',"
            }

    // remove last "," add "]" and set the args 
    return cla.substring(0, cla.lastIndexOf(',')) + "]"
}

my task looks like this:

task runProgram(type: JavaExec) {
    if ( project.hasProperty("commandLineArgs") ) {
            args Eval.me( setCommandLineArguments(commandLineArgs) )
    }
}

To pass the arguments from the command line you run this:

gradle runProgram -PcommandLineArgs="arg1 arg2 arg3 arg4"    

res/drawable/day_selector.xml

    <?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android" >
        <item android:drawable="@drawable/dayselectionunselected"
              android:state_checked="false"/>
        <item android:drawable="@drawable/daysselectionselected"
              android:state_checked="true"/>
        <item android:drawable="@drawable/dayselectionunselected"/>
    </selector>

res/layout/my_layout.xml

<CheckBox
    android:id="@+id/check"
    android:layout_width="39dp"
    android:layout_height="39dp"
    android:background="@drawable/day_selector"
    android:button="@null"
    android:gravity="center"
    android:text="S"
    android:textColor="@color/black"
    android:textSize="12sp" />

If I use Firefox then screen.width and screen.height works fine but in IE and Chrome they don't work properly instead it opens with the minimum size.

And yes I tried giving too large numbers too like 10000 for both height and width but not exactly the maximized effect.

$arrayDecoded = json_decode($arrayEncoded, true);

gives you an array.

It turns out setting these configuration properties is pretty straight forward, but the official documentation is more general so it might be hard to find when searching specifically for connection pool configuration information.

To set the maximum pool size for tomcat-jdbc, set this property in your .properties or .yml file:

spring.datasource.maxActive=5

You can also use the following if you prefer:

spring.datasource.max-active=5

You can set any connection pool property you want this way. Here is a complete list of properties supported by tomcat-jdbc.

To understand how this works more generally you need to dig into the Spring-Boot code a bit.

Spring-Boot constructs the DataSource like this (see here, line 102):

@ConfigurationProperties(prefix = DataSourceAutoConfiguration.CONFIGURATION_PREFIX)
@Bean
public DataSource dataSource() {
    DataSourceBuilder factory = DataSourceBuilder
            .create(this.properties.getClassLoader())
            .driverClassName(this.properties.getDriverClassName())
            .url(this.properties.getUrl())
            .username(this.properties.getUsername())
            .password(this.properties.getPassword());
    return factory.build();
}

The DataSourceBuilder is responsible for figuring out which pooling library to use, by checking for each of a series of know classes on the classpath. It then constructs the DataSource and returns it to the dataSource() function.

At this point, magic kicks in using @ConfigurationProperties. This annotation tells Spring to look for properties with prefix CONFIGURATION_PREFIX (which is spring.datasource). For each property that starts with that prefix, Spring will try to call the setter on the DataSource with that property.

The Tomcat DataSource is an extension of DataSourceProxy, which has the method setMaxActive().

And that's how your spring.datasource.maxActive=5 gets applied correctly!

What about other connection pools

I haven't tried, but if you are using one of the other Spring-Boot supported connection pools (currently HikariCP or Commons DBCP) you should be able to set the properties the same way, but you'll need to look at the project documentation to know what is available.

This code is in the wrong place:

var image : UIImage = UIImage(named:"afternoon")!
bgImage = UIImageView(image: image)
bgImage.frame = CGRect(x: 0, y: 0, width: 100, height: 200)
view.addSubview(bgImage)

You must place it inside a function. I recommend moving it inside the viewDidLoad function.

In general, the only code you can add within the class that's not inside of a function are variable declarations like:

@IBOutlet weak var bgImage: UIImageView!

The question title says "How can I simulate an anchor click in jQuery?". Well, you can use the "trigger" or "triggerHandler" methods, like so:

<script type="text/javascript" src="path/to/jquery.js"></script>
<script type="text/javascript" src="path/to/thickbox.js"></script>
<script type="text/javascript">
$(function() {
    $('#btn').click(function() {
        $('#thickboxId').triggerHandler('click');
    })
})
</script>
...
<input id="btn" type="button" value="Click me">
<a id="thickboxId" href="myScript.php" class="thickbox" title="">Link</a>

Not tested, this actual script, but I've used trigger et al before, and they worked a'ight.

UPDATE
triggerHandler doesn't actually do what the OP wants. I think 1421968 provides the best answer to this question.

To create a "drop down menu" you can use OptionMenu in tkinter

Example of a basic OptionMenu:

from Tkinter import *

master = Tk()

variable = StringVar(master)
variable.set("one") # default value

w = OptionMenu(master, variable, "one", "two", "three")
w.pack()

mainloop()

More information (including the script above) can be found here.

Creating an OptionMenu of the months from a list would be as simple as:

from tkinter import *

OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc

master = Tk()

variable = StringVar(master)
variable.set(OPTIONS[0]) # default value

w = OptionMenu(master, variable, *OPTIONS)
w.pack()

mainloop()

In order to retrieve the value the user has selected you can simply use a .get() on the variable that we assigned to the widget, in the below case this is variable:

from tkinter import *

OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc

master = Tk()

variable = StringVar(master)
variable.set(OPTIONS[0]) # default value

w = OptionMenu(master, variable, *OPTIONS)
w.pack()

def ok():
    print ("value is:" + variable.get())

button = Button(master, text="OK", command=ok)
button.pack()

mainloop()

I would highly recommend reading through this site for further basic tkinter information as the above examples are modified from that site.

I simply declared as below in web.xml file and Its working for me :

 <welcome-file-list>
    <welcome-file>/WEB-INF/jsps/index.jsp</welcome-file>
</welcome-file-list>

And NO html/jsp pages present in public directory except static resources(css, js, images). Now I can access my index page with URL like : http://localhost:8080/app/ Its calling /WEB-INF/jsps/index.jsp page. When hosted live in production the final URL looks like https://eisdigital.com/

SQL Server database engine service account must have permissions to read/write in the new folder.

Check out this

To fix, I did the following:

Added the Administrators Group to the file security permissions with full control for the Data file (S:) and the Log File (T:).

Attached the database and it works fine.

In regards to testing if a module you are utilizing is secure or not there are several routes you can take. I will touch on the pros/cons of each so you can make a more informed decision.

Currently, there aren't any vulnerabilities for the module you are utilizing, however, this can often lead to a false sense of security as there very well could be a vulnerability currently exploiting the module/software package you are using and you wouldn't be alerted to a problem until the vendor applies a fix/patch.

1. To keep abreast of vulnerabilities you will need to follow mailing lists, forums, IRC & other hacking related discussions. PRO: You can often times you will become aware of potential problems within a library before a vendor has been alerted or has issued a fix/patch to remedy the potential avenue of attack on their software. CON: This can be very time consuming and resource intensive. If you do go this route a bot using RSS feeds, log parsing (IRC chat logs) and or a web scrapper using key phrases (in this case node-mysql-native) and notifications can help reduce time spent trolling these resources.

2. Create a fuzzer, use a fuzzer or other vulnerability framework such as metasploit, sqlMap etc. to help test for problems that the vendor may not have looked for. PRO: This can prove to be a sure fire method of ensuring to an acceptable level whether or not the module/software you are implementing is safe for public access. CON: This also becomes time consuming and costly. The other problem will stem from false positives as well as uneducated review of the results where a problem resides but is not noticed.

Really security, and application security in general can be very time consuming and resource intensive. One thing managers will always use is a formula to determine the cost effectiveness (manpower, resources, time, pay etc) of performing the above two options.

Anyways, I realize this is not a 'yes' or 'no' answer that may have been hoping for but I don't think anyone can give that to you until they perform an analysis of the software in question.

According to http://www.techotopia.com/index.php/Ruby_String_Concatenation_and_Comparison

Doing either

mystring == yourstring

or

mystring.eql? yourstring

Are equivalent.

This fiddle has both each and direct json. http://jsfiddle.net/streethawk707/a9ssja22/.

Below are the two ways of iterating over array. One is with direct json passing and another is naming the json array while passing to content holder.

Eg1: The below example is directly calling json key (data) inside small_data variable.

In html use the below code:

<div id="small-content-placeholder"></div>

The below can be placed in header or body of html:

<script id="small-template" type="text/x-handlebars-template">
    <table>
        <thead>
            <th>Username</th>
            <th>email</th>
        </thead>
        <tbody>
            {{#data}}
                <tr>
                    <td>{{username}}
                    </td>
                    <td>{{email}}</td>
                </tr>
            {{/data}}
        </tbody>
    </table>
</script>

The below one is on document ready:

var small_source   = $("#small-template").html();
var small_template = Handlebars.compile(small_source);

The below is the json:

var small_data = {
            data: [
                {username: "alan1", firstName: "Alan", lastName: "Johnson", email: "[email protected]" },
                {username: "alan2", firstName: "Alan", lastName: "Johnson", email: "[email protected]" }
            ]
        };

Finally attach the json to content holder:

$("#small-content-placeholder").html(small_template(small_data));

Eg2: Iteration using each.

Consider the below json.

var big_data = [
            {
                name: "users1",
                details: [
                    {username: "alan1", firstName: "Alan", lastName: "Johnson", email: "[email protected]" },
                    {username: "allison1", firstName: "Allison", lastName: "House", email: "[email protected]" },
                    {username: "ryan1", firstName: "Ryan", lastName: "Carson", email: "[email protected]" }
                  ]
            },
            {

While passing the json to content holder just name it in this way:

$("#big-content-placeholder").html(big_template({big_data:big_data}));

And the template looks like :

<script id="big-template" type="text/x-handlebars-template">
    <table>
        <thead>
            <th>Username</th>
            <th>email</th>
        </thead>
        <tbody>
            {{#each big_data}}
                <tr>
                    <td>{{name}}
                            <ul>
                                {{#details}}
                                    <li>{{username}}</li>
                                    <li>{{email}}</li>
                                {{/details}}
                            </ul>
                    </td>
                    <td>{{email}}</td>
                </tr>
            {{/each}}
        </tbody>
    </table>
</script>

In terminal type the command:

xattr -d com.apple.quarantine [file path here]

Once you click enter it will no longer have that problem. Its annoying that apple adds a quarantine to files automatically. I do not know how to turn this off but there probably is a way...

I tried 600 level of permission for my private key and it worked for me. chmod 600 privateKey [dev]$ ssh -i privateKey user@ip worked

chmod 755 privateKey [dev]$ ssh -i privateKey user@ip it was giving below issue: Permissions 0755 for 'privateKey' are too open. It is required that your private key files are NOT accessible by others. This private key will be ignored. Load key "privateKey": bad permissions

First off:

public class ProfileCollection implements Iterable<Profile> {

Second:

return m_Profiles.get(m_ActiveProfile);

Regarding the 64-bit system wanting 32-bit support. I don't find it so bizarre:

Although deployed to a 64-bit system, this doesn't mean all the referenced assemblies are necessarily 64-bit Crystal Reports assemblies. Further to that, the Crystal Reports assemblies are largely just wrappers to a collection of legacy DLLs upon which they are based. Many 32-bit DLLs are required by the primarily referenced assembly. The error message "can not load the assembly" involves these DLLs as well. To see visually what those are, go to www.dependencywalker.com and run 'Depends' on the assembly in question, directly on that IIS server.

Because the Method2 is static, all you have to do is call like this:

public class AllMethods
{
    public static void Method2()
    {
        // code here
    }
}

class Caller
{
    public static void Main(string[] args)
    {
        AllMethods.Method2();
    }
}

If they are in different namespaces you will also need to add the namespace of AllMethods to caller.cs in a using statement.

If you wanted to call an instance method (non-static), you'd need an instance of the class to call the method on. For example:

public class MyClass
{
    public void InstanceMethod() 
    { 
        // ...
    }
}

public static void Main(string[] args)
{
    var instance = new MyClass();
    instance.InstanceMethod();
}

Update

As of C# 6, you can now also achieve this with using static directive to call static methods somewhat more gracefully, for example:

// AllMethods.cs
namespace Some.Namespace
{
    public class AllMethods
    {
        public static void Method2()
        {
            // code here
        }
    }
}

// Caller.cs
using static Some.Namespace.AllMethods;

namespace Other.Namespace
{
    class Caller
    {
        public static void Main(string[] args)
        {
            Method2(); // No need to mention AllMethods here
        }
    }
}
