One thing a lot of people don't know is that multi-line configuration-values are allowed. For example:

;test.ini
[hello]
barlist = 
    item1
    item2

The value of config.get('hello','barlist') will now be:

"\nitem1\nitem2"

Which you easily can split with the splitlines method (don't forget to filter empty items).

If we look to a big framework like Pyramid they are using this technique:

def aslist_cronly(value):
    if isinstance(value, string_types):
        value = filter(None, [x.strip() for x in value.splitlines()])
    return list(value)

def aslist(value, flatten=True):
    """ Return a list of strings, separating the input based on newlines
    and, if flatten=True (the default), also split on spaces within
    each line."""
    values = aslist_cronly(value)
    if not flatten:
        return values
    result = []
    for value in values:
        subvalues = value.split()
        result.extend(subvalues)
    return result

Source

Myself, I would maybe extend the ConfigParser if this is a common thing for you:

class MyConfigParser(ConfigParser):
    def getlist(self,section,option):
        value = self.get(section,option)
        return list(filter(None, (x.strip() for x in value.splitlines())))

    def getlistint(self,section,option):
        return [int(x) for x in self.getlist(section,option)]

Note that there are a few things to look out for when using this technique

1. New lines that are items should start with whitespace (e.g. a space or a tab)
2. All following lines that start with whitespace are considered to be part of the previous item. Also if it has an = sign or if it starts with a ; following the whitespace.

Another python3 implementation that involves the use of Abstract classes with super(). You should remember that

super().__init__(name, 10)

has the same effect as

Person.__init__(self, name, 10)

Remember there's a hidden 'self' in super(), So the same object passes on to the superclass init method and the attributes are added to the object that called it. Hence super()gets translated to Person and then if you include the hidden self, you get the above code frag.

from abc import ABCMeta, abstractmethod
class Person(metaclass=ABCMeta):
    name = ""
    age = 0

    def __init__(self, personName, personAge):
        self.name = personName
        self.age = personAge

    @abstractmethod
    def showName(self):
        pass

    @abstractmethod
    def showAge(self):
        pass


class Man(Person):

    def __init__(self, name, height):
        self.height = height
        # Person.__init__(self, name, 10)
        super().__init__(name, 10)  # same as Person.__init__(self, name, 10)
        # basically used to call the superclass init . This is used incase you want to call subclass init
        # and then also call superclass's init.
        # Since there's a hidden self in the super's parameters, when it's is called,
        # the superclasses attributes are a part of the same object that was sent out in the super() method

    def showIdentity(self):
        return self.name, self.age, self.height

    def showName(self):
        pass

    def showAge(self):
        pass


a = Man("piyush", "179")
print(a.showIdentity())

put the below code in attrs.xml in resource>>values

  <declare-styleable name="ShadowLayout">

EDIT If you are interested in removing the white borders at the edges, use a width and height of 110% and a left and top of -5%. This will enlarge your backgrounds a tad - but there should be no solid colour bleeding in from the edges. Thanks Chad Fawcett for the suggestion.

window.location.href = 'URL';

is the standard implementation for changing the current window's location.

you can retrieve value like this

string str = (string)(range.Cells[row, col] as Excel.Range).Value2 ;

select entire used range

Excel.Range range = xlWorkSheet.UsedRange;

You use flatMap when you have an Observable whose results are more Observables.

If you have an observable which is produced by an another observable you can not filter, reduce, or map it directly because you have an Observable not the data. If you produce an observable choose flatMap over map; then you are okay.

As in second snippet, if you are doing async operation you need to use flatMap.

var source = Rx.Observable.interval(100).take(10).map(function(num){_x000D_
    return num+1_x000D_
});_x000D_
source.subscribe(function(e){_x000D_
    console.log(e)_x000D_
})

var source = Rx.Observable.interval(100).take(10).flatMap(function(num){_x000D_
    return Rx.Observable.timer(100).map(() => num)_x000D_

As per latest updates, caskroom packages have moved to homebrew. So try following commands:

brew tap homebrew/cask
brew cask install sublime-text

These 2 terminal commands will be enough for installing sublime.

How about ioreg? The output's much more detailed than the profiler, but it's a bit dense.

The simplest external tool that I found that is also portable is jisql - https://www.xigole.com/software/jisql/jisql.jsp . You would run it as:

java -classpath lib/jisql.jar:\
          lib/jopt-simple-3.2.jar:\
          lib/javacsv.jar:\
           /home/scott/postgresql/postgresql-8.4-701.jdbc4.jar 
    com.xigole.util.sql.Jisql -user scott -password blah     \
    -driver postgresql                                       \
    -cstring jdbc:postgresql://localhost:5432/scott -c \;    \
    -query "select * from test;"

This code can also compare floats. It is using awk (it is not pure bash), however this shouldn't be a problem, as awk is a standard POSIX command that is most likely shipped by default with your operating system.

$ awk 'BEGIN {return_code=(-1.2345 == -1.2345) ? 0 : 1; exit} END {exit return_code}'
$ echo $?
0
$ awk 'BEGIN {return_code=(-1.2345 >= -1.2345) ? 0 : 1; exit} END {exit return_code}'
$ echo $?
0
$ awk 'BEGIN {return_code=(-1.2345 < -1.2345) ? 0 : 1; exit} END {exit return_code}'
$ echo $?
1
$ awk 'BEGIN {return_code=(-1.2345 < 2) ? 0 : 1; exit} END {exit return_code}'
$ echo $?
0
$ awk 'BEGIN {return_code=(-1.2345 > 2) ? 0 : 1; exit} END {exit return_code}'
$ echo $?

To make it shorter for use, use this function:

compare_nums()
{
   # Function to compare two numbers (float or integers) by using awk.
   # The function will not print anything, but it will return 0 (if the comparison is true) or 1
   # (if the comparison is false) exit codes, so it can be used directly in shell one liners.
   #############
   ### Usage ###
   ### Note that you have to enclose the comparison operator in quotes.
   #############
   # compare_nums 1 ">" 2 # returns false
   # compare_nums 1.23 "<=" 2 # returns true
   # compare_nums -1.238 "<=" -2 # returns false
   #############################################
   num1=$1
   op=$2
   num2=$3
   E_BADARGS=65

   # Make sure that the provided numbers are actually numbers.
   if ! [[ $num1 =~ ^-?[0-9]+([.][0-9]+)?$ ]]; then >&2 echo "$num1 is not a number"; return $E_BADARGS; fi
   if ! [[ $num2 =~ ^-?[0-9]+([.][0-9]+)?$ ]]; then >&2 echo "$num2 is not a number"; return $E_BADARGS; fi

   # If you want to print the exit code as well (instead of only returning it), uncomment
   # the awk line below and comment the uncommented one which is two lines below.
   #awk 'BEGIN {print return_code=('$num1' '$op' '$num2') ? 0 : 1; exit} END {exit return_code}'
   awk 'BEGIN {return_code=('$num1' '$op' '$num2') ? 0 : 1; exit} END {exit return_code}'
   return_code=$?
   return $return_code
}

$ compare_nums -1.2345 ">=" -1.2345 && echo true || echo false
true
$ compare_nums -1.2345 ">=" 23 && echo true || echo false
false

First, is 40 collisions for 130 words hashed to 0..99 bad? You can't expect perfect hashing if you are not taking steps specifically for it to happen. An ordinary hash function won't have fewer collisions than a random generator most of the time.

A hash function with a good reputation is MurmurHash3.

Finally, regarding the size of the hash table, it really depends what kind of hash table you have in mind, especially, whether buckets are extensible or one-slot. If buckets are extensible, again there is a choice: you choose the average bucket length for the memory/speed constraints that you have.

You can use std::to_string in C++11

long val = 12345;
std::string my_val = std::to_string(val);

also, you can fetch all data and count in the blade file. for example:

your code in the controller

$posts = Post::all();
return view('post', compact('posts'));

your code in the blade file.

{{ $posts->count() }}

finally, you can see the total of your posts.

Remove the public keyword from int[] locations={1,2,3};. An access modifier isn't allowed inside a method, as its accessbility is defined by its method scope.

If your goal is to use this reference in many a method, you might want to move the declaration outside the method.

Recently I was helping a friend to find why their carousel was not working. Controls would not work and images were not transitioning. I had a working sample on a page I had used and we went through all the code including checking the items above in this post. We pasted the "good" carousel into the same page and it still worked. Now, all css and bootstrap files were the same for both. The code was now identical, so all we could try was the images.

So, we replaced the images with two that were working in my sample. It worked. We replaced the two images with the first two that were originally not working, and it worked. We added back each image (all jpegs) one-by-one, and when we got to the seventh image (of 18) and the carousel failed. Weird. We removed this one image and continued to add the remaining images until they were all added and the carousel worked.

for reference, we were using jquery-3.3.1.slim.min.js and bootstrap/4.3.1/js/bootstrap.min.js on this site.

I do not know why an image would or could cause a carousel to malfunction, but it did. I couldn't find a reference to this cause elsewhere either, so I'm posting here for posterity in the hope that it might help someone else when other solutions fail.

Test carousel with limited set of "known-to-be-good" images.

Here's an answer to a 2-year old question in case it helps anyone else with the same problem.

Based upon the information you've provided, a permissions issue on the file (or files) would be one cause of the same 500 Internal Server Error.

To check whether this is the problem (if you can't get more detailed information on the error), navigate to the directory in Terminal and run the following command:

ls -la

If you see limited permissions - e.g. -rw-------@ against your file, then that's your problem.

The solution then is to run chmod 644 on the problem file(s) or chmod 755 on the directories. See this answer - How do I set chmod for a folder and all of its subfolders and files? - for a detailed explanation of how to change permissions.

By way of background, I had precisely the same problem as you did on some files that I had copied over from another Mac via Google Drive, which transfer had stripped most of the permissions from the files.

The screenshot below illustrates. The index.php file with the -rw-------@ permissions generates a 500 Internal Server Error, while the index_finstuff.php (precisely the same content!) with -rw-r--r--@ permissions is fine. Changing the permissions on the index.php immediately resolves the problem.

In other words, your PHP code and the server may both be fine. However, the limited read permissions on the file may be forbidding the server from displaying the content, causing the 500 Internal Server Error message to be displayed instead.

-(void)buttonTouched:(id)sender
{
    UIButton *btn = (UIButton *)sender;

    if( [[btn imageForState:UIControlStateNormal] isEqual:[UIImage imageNamed:@"icon-Locked.png"]])
    {
        [btn setImage:[UIImage imageNamed:@"icon-Unlocked.png"] forState:UIControlStateNormal];
        // other statements....
    }
    else
    {
        [btn setImage:[UIImage imageNamed:@"icon-Locked.png"] forState:UIControlStateNormal];
        // other statements....
    }
}

I think the best way to secure your credential is to first think of storing the Password with encryption in the account.db file which couldn't be easily available in non rooted devices and in case of rooted device the hacker must need the key to decrypt it.

Other option is do all your authentication like the way Gmail is doing. after the first authentication with the Gmail server . you got the Auth Token that would be use in case of your password . that token would be store in plain text.this token could be false in case you change the password from Server.

the last option I'd recommend you to enable 2-Factor Authentication & create Device Specific Password for your device. After losing device, all you need is to disable that device.

Steps I used to resolve it:

1. Double click on Tomcat Server in the Servers tab.
2. In a dropdown next to Runtime Environment:, select Apache Tomcat your version
3. Click on save.

Now, you should be able to add to server on right click "Add and Remove".

Note: Additionally, when on clear/run, you get an error for multiple instances, open server.xml and ensure that it contains a single instance of each application and not multiple.

Function pointers are a great way to do this, e.g.

result = switchFunction(someStringKey); //result is an optional return value

...this calls a function that you have set by string key (one function per case):

setSwitchFunction("foo", fooFunc);
setSwitchFunction("bar", barFunc);

Use a pre-existing hashmap/table/dictionary implementation such as khash, return that pointer to a function inside of switchFunction(), and execute it (or just return it from switchFunction() and execute it yourself). If the map implementation doesn't store that, just use a uint64_t instead that you cast accordingly to a pointer.

Above you'll find all differents ways to iterate over a LIST.

    System.out.println("//******* Exercise 2");
    List<Integer> list2 = Arrays.asList(1, 2, 3, 4, 5, 6, 7);
    
    // iteration type 1 : using FOR loop

One of the approaches may be like this:

1) Create a CSS file with name "style.css" and define an id selector in it:

#pane{
    -fx-background-image: url("background_image.jpg");
    -fx-background-repeat: stretch;   
    -fx-background-size: 900 506;
    -fx-background-position: center center;
    -fx-effect: dropshadow(three-pass-box, black, 30, 0.5, 0, 0); 
}

2) Set the id of the most top control (or any control) in the scene with value defined in CSS and load this CSS file into the scene:

  public class Test extends Application {

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

    @Override
    public void start(Stage primaryStage) {
        StackPane root = new StackPane();
        root.setId("pane");
        Scene scene = new Scene(root, 300, 250);
        scene.getStylesheets().addAll(this.getClass().getResource("style.css").toExternalForm());
        primaryStage.setScene(scene);
        primaryStage.show();
    }
}

You can also give an id to the control in a FXML file:

<StackPane id="pane" prefHeight="200" prefWidth="320" xmlns:fx="http://javafx.com/fxml" fx:controller="demo.Sample">
    <children>
    </children>
</StackPane>

For more info about JavaFX CSS Styling refer to this guide.

You can't use Template expression operators(pipe, save navigator) within template statement:

(ngModelChange)="Template statements"

(ngModelChange)="item.value | useMyPipeToFormatThatValue=$event"

https://angular.io/guide/template-syntax#template-statements

Like template expressions, template statements use a language that looks like JavaScript. The template statement parser differs from the template expression parser and specifically supports both basic assignment (=) and chaining expressions (with ; or ,).

However, certain JavaScript syntax is not allowed:

• new
• increment and decrement operators, ++ and --
• operator assignment, such as += and -=
• the bitwise operators | and &
• the template expression operators

So you should write it as follows:

<input [ngModel]="item.value | useMyPipeToFormatThatValue" 
      (ngModelChange)="item.value=$event" name="inputField" type="text" />

Plunker Example

Google's solution:

Creating the Table

When you create the MySQL table, you want to pay particular attention to the lat and lng attributes. With the current zoom capabilities of Google Maps, you should only need 6 digits of precision after the decimal. To keep the storage space required for your table at a minimum, you can specify that the lat and lng attributes are floats of size (10,6). That will let the fields store 6 digits after the decimal, plus up to 4 digits before the decimal, e.g. -123.456789 degrees. Your table should also have an id attribute to serve as the primary key.

CREATE TABLE `markers` (
  `id` INT NOT NULL AUTO_INCREMENT PRIMARY KEY ,
  `name` VARCHAR( 60 ) NOT NULL ,
  `address` VARCHAR( 80 ) NOT NULL ,
  `lat` FLOAT( 10, 6 ) NOT NULL ,
  `lng` FLOAT( 10, 6 ) NOT NULL
) ENGINE = MYISAM ;

Populating the Table

After creating the table, it's time to populate it with data. The sample data provided below is for about 180 pizzarias scattered across the United States. In phpMyAdmin, you can use the IMPORT tab to import various file formats, including CSV (comma-separated values). Microsoft Excel and Google Spreadsheets both export to CSV format, so you can easily transfer data from spreadsheets to MySQL tables through exporting/importing CSV files.

INSERT INTO `markers` (`name`, `address`, `lat`, `lng`) VALUES ('Frankie Johnnie & Luigo Too','939 W El Camino Real, Mountain View, CA','37.386339','-122.085823');
INSERT INTO `markers` (`name`, `address`, `lat`, `lng`) VALUES ('Amici\'s East Coast Pizzeria','790 Castro St, Mountain View, CA','37.38714','-122.083235');
INSERT INTO `markers` (`name`, `address`, `lat`, `lng`) VALUES ('Kapp\'s Pizza Bar & Grill','191 Castro St, Mountain View, CA','37.393885','-122.078916');
INSERT INTO `markers` (`name`, `address`, `lat`, `lng`) VALUES ('Round Table Pizza: Mountain View','570 N Shoreline Blvd, Mountain View, CA','37.402653','-122.079354');
INSERT INTO `markers` (`name`, `address`, `lat`, `lng`) VALUES ('Tony & Alba\'s Pizza & Pasta','619 Escuela Ave, Mountain View, CA','37.394011','-122.095528');
INSERT INTO `markers` (`name`, `address`, `lat`, `lng`) VALUES ('Oregano\'s Wood-Fired Pizza','4546 El Camino Real, Los Altos, CA','37.401724','-122.114646');

Finding Locations with MySQL

To find locations in your markers table that are within a certain radius distance of a given latitude/longitude, you can use a SELECT statement based on the Haversine formula. The Haversine formula is used generally for computing great-circle distances between two pairs of coordinates on a sphere. An in-depth mathemetical explanation is given by Wikipedia and a good discussion of the formula as it relates to programming is on Movable Type's site.

Here's the SQL statement that will find the closest 20 locations that are within a radius of 25 miles to the 37, -122 coordinate. It calculates the distance based on the latitude/longitude of that row and the target latitude/longitude, and then asks for only rows where the distance value is less than 25, orders the whole query by distance, and limits it to 20 results. To search by kilometers instead of miles, replace 3959 with 6371.

SELECT 
id, 
(
   3959 *
   acos(cos(radians(37)) * 
   cos(radians(lat)) * 
   cos(radians(lng) - 
   radians(-122)) + 
   sin(radians(37)) * 
   sin(radians(lat )))
) AS distance 
FROM markers 
HAVING distance < 28 
ORDER BY distance LIMIT 0, 20;

This one is to find latitudes and longitudes in a distance less than 28 miles.

Another one is to find them in a distance between 28 and 29 miles:

SELECT 
id, 
(
   3959 *
   acos(cos(radians(37)) * 
   cos(radians(lat)) * 
   cos(radians(lng) - 
   radians(-122)) + 
   sin(radians(37)) * 
   sin(radians(lat )))
) AS distance 
FROM markers 
HAVING distance < 29 and distance > 28 
ORDER BY distance LIMIT 0, 20;

https://developers.google.com/maps/articles/phpsqlsearch_v3#creating-the-map

Here is another approach using getter and setter functions for the model.

@Component({
  selector: 'input-language',
  template: `
  …
  <input 
    type="text" 
    placeholder="Language" 
    [(ngModel)]="query" 
  />
  `,
})
export class InputLanguageComponent {

  set query(value) {
    this._query = value;
    console.log('query set to :', value)
  }

  get query() {
    return this._query;
  }
}

In case if you are using node js, then this could be the possible solution

const express = require("express");
const app = express();
const server = app.listen(8080);
server.keepAliveTimeout = 61 * 1000;

The second one is a classic example of the Arrow Anti-pattern So I'd avoid it...

If your conditions are too long extract them into methods/properties.

One thing that happened for me is that the version of R provided by my linux distribution (R version 3.0.2 provided by Ubuntu 14.04) was too old for the latest version of the package available on CRAN (in my case, plyr version 1.8.3 as of today). The solution was to use the packaging system of my distribution instead of trying to install from R (apt-get install r-cran-plyr got me version 1.8.1 of plyr). Maybe I could have tried to update R using updateR(), but I'm afraid that doing so would interfere with my distribution's package manager.

Edit (04/08/2020): I recently had an issue with a package (XML) reportedly not available for my R version (3.6.3, latest supported on Debian stretch), after an update of the package in CRAN. It was very unexpected because I already had installed it with success before (on the same version of R and same OS).

For some reason, the package was still there, but install.packages was only looking at the updated (and incompatible) version. The solution was to find the URL of the compatible version and force install.packages to use it, as follows:

install.packages("https://cran.r-project.org/src/contrib/Archive/XML/XML_3.99-0.3.tar.gz", repos=NULL, type="source", ask=FALSE)

You want to assign something like this to onfocus:

if (this.value == this.defaultValue)
    this.value = ''
this.className = ''

and this to onblur:

if (this.value == '')
    this.value = this.defaultValue
this.className = 'placeholder'

(You can use something a bit cleverer, like a framework function, to do the classname switching if you want.)

With some CSS like this:

input.placeholder{
    color: gray;
    font-style: italic;
}

I had to go look for ojdbc compatible with version on oracle that was installed this fixed my problem, my bad was thinking one ojdbc would work for all

For those using anaconda Python:

conda update anaconda

The answer by @felix almost brought me there. I had two issues:

1. With Gradle 1.5, the manifest tag was not recognised inside the fatJar task, so the Main-Class attribute could not directly be set
2. the jar had conflicting external META-INF files.

The following setup resolves this

jar {
  manifest {
    attributes(
      'Main-Class': 'my.project.main',
    )
  }
}

task fatJar(type: Jar) {
  manifest.from jar.manifest
  classifier = 'all'
  from {
    configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
  } {
    exclude "META-INF/*.SF"
    exclude "META-INF/*.DSA"
    exclude "META-INF/*.RSA"
  }
  with jar
}

To add this to the standard assemble or build task, add:

artifacts {
    archives fatJar
}

Edit: thanks to @mjaggard: in recent versions of Gradle, change configurations.runtime to configurations.runtimeClasspath

#include <experimental/filesystem> // or #include <filesystem> for C++17 and up
    
namespace fs = std::experimental::filesystem;


if (!fs::is_directory("src") || !fs::exists("src")) { // Check if src folder exists
    fs::create_directory("src"); // create src folder
}

Running these commands solved my problem (credit to this answer):

import django
django.setup()

However I'm not sure why I need this. Comments would be appreciated.

import re
pattern = re.compile("<(\d{4,5})>")

for i, line in enumerate(open('test.txt')):
    for match in re.finditer(pattern, line):
        print 'Found on line %s: %s' % (i+1, match.group())

A couple of notes about the regex:

• You don't need the ? at the end and the outer (...) if you don't want to match the number with the angle brackets, but only want the number itself
• It matches either 4 or 5 digits between the angle brackets

Update: It's important to understand that the match and capture in a regex can be quite different. The regex in my snippet above matches the pattern with angle brackets, but I ask to capture only the internal number, without the angle brackets.

More about regex in python can be found here : Regular Expression HOWTO

You should not extend the JFrame class unnecessarily (only if you are adding extra functionality to the JFrame class)

JFrame:

JFrame extends Component and Container.

It is a top level container used to represent the minimum requirements for a window. This includes Borders, resizability (is the JFrame resizeable?), title bar, controls (minimize/maximize allowed?), and event handlers for various Events like windowClose, windowOpened etc.

JPanel:

JPanel extends Component, Container and JComponent

It is a generic class used to group other Components together.

• It is useful when working with LayoutManagers e.g. GridLayout f.i adding components to different JPanels which will then be added to the JFrame to create the gui. It will be more manageable in terms of Layout and re-usability.

• It is also useful for when painting/drawing in Swing, you would override paintComponent(..) and of course have the full joys of double buffering.

A Swing GUI cannot exist without a top level container like (JWindow, Window, JFrame Frame or Applet), while it may exist without JPanels.

No, according to Apple here:

Note: You cannot install apps from the App Store in simulation environments.

The Pythonic way to create a static class is simply to declare those methods outside of a class (Java uses classes both for objects and for grouping related functions, but Python modules are sufficient for grouping related functions that do not require any object instance). However, if you insist on making a method at the class level that doesn't require an instance (rather than simply making it a free-standing function in your module), you can do so by using the "@staticmethod" decorator.

That is, the Pythonic way would be:

# My module
elements = []

def add_element(x):
  elements.append(x)

But if you want to mirror the structure of Java, you can do:

# My module
class World(object):
  elements = []

  @staticmethod
  def add_element(x):
    World.elements.append(x)

You can also do this with @classmethod if you care to know the specific class (which can be handy if you want to allow the static method to be inherited by a class inheriting from this class):

# My module
class World(object):
  elements = []

  @classmethod
  def add_element(cls, x):
    cls.elements.append(x)

sizeof returns the size of the type of the variable in bytes. So in your case it's returning the size of your char[7] which is 7 * sizeof(char). Since sizeof(char) = 1, the result is 7.

Expanding this to another example:

int intArr[5];
printf("sizeof(intArr)=%u", sizeof(intArr));

would yield 5 * sizeof(int), so you'd get the result "20" (At least on a regular 32bit platform. On others sizeof(int) might differ)

To return to your problem:

It seems like, that what you want to know is the length of the string which is contained inside your array and not the total array size.

By definition C-Strings have to be terminated with a trailing '\0' (0-Byte). So to get the appropriate length of the string contained within your array, you have to first terminate the string, so that you can tell when it's finished. Otherwise there would be now way to know.

All standard functions build upon this definition, so if you call strlen to retrieve the str ing len gth, it will iterate through the given array until it finds the first 0-byte, which in your case would be the very first element.

Another thing you might need to know that only because you don't fill the remaining elements of your char[7] with a value, they actually do contain random undefined values.

Hope that helped.

I like to use the program Artistic Style. According to their website:

Artistic Style is a source code indenter, formatter, and beautifier for the C, C++, C# and Java programming languages.

It runs in Window, Linux and Mac. It will do things like indenting, replacing tabs with spaces or vice-versa, putting spaces around operations however you like (converting if(x<2) to if ( x<2 ) if that's how you like it), putting braces on the same line as function definitions, or moving them to the line below, etc. All the options are controlled by command line parameters.

In order to use it in vim, just set the formatprg option to it, and then use the gq command. So, for example, I have in my .vimrc:

autocmd BufNewFile,BufRead *.cpp set formatprg=astyle\ -T4pb

so that whenever I open a .cpp file, formatprg is set with the options I like. Then, I can type gg to go to the top of the file, and gqG to format the entire file according to my standards. If I only need to reformat a single function, I can go to the top of the function, then type gq][ and it will reformat just that function.

The options I have for astyle, -T4pb, are just my preferences. You can look through their docs, and change the options to have it format the code however you like.

Here's a demo. Before astyle:

int main(){if(x<2){x=3;}}

float test()
{
if(x<2)
x=3;
}

After astyle (gggqG):

int main()
{
    if (x < 2)
    {
        x = 3;
    }
}

float test()
{
    if (x < 2)
        x = 3;
}

Hope that helps.

I think what you are asking is the difference between RPC Literal, Document Literal and Document Wrapped SOAP web services.

Note that Document web services are delineated into literal and wrapped as well and they are different - one of the primary difference is that the latter is BP 1.1 compliant and the former is not.

Also, in Document Literal the operation to be invoked is not specified in terms of its name whereas in Wrapped, it is. This, I think, is a significant difference in terms of easily figuring out the operation name that the request is for.

In terms of RPC literal versus Document Wrapped, the Document Wrapped request can be easily vetted / validated against the schema in the WSDL - one big advantage.

I would suggest using Document Wrapped as the web service type of choice due to its advantages.

SOAP on HTTP is the SOAP protocol bound to HTTP as the carrier. SOAP could be over SMTP or XXX as well. SOAP provides a way of interaction between entities (client and servers, for example) and both entities can marshal operation arguments / return values as per the semantics of the protocol.

If you were using XML over HTTP (and you can), it is simply understood to be XML payload on HTTP request / response. You would need to provide the framework to marshal / unmarshal, error handling and so on.

A detailed tutorial with examples of WSDL and code with emphasis on Java: SOAP and JAX-WS, RPC versus Document Web Services

Your compiler may have a warning that it can generate if a base class function becomes hidden. If it does, enable it. That will catch const clashes and differences in parameter lists. Unfortunately this won't uncover a spelling error.

For example, this is warning C4263 in Microsoft Visual C++.

Try adding these after <Playlist>

<AutoLoad>false</AutoLoad>
<AutoPlay>false</AutoPlay>

Microsoft has a special note on this (https://msdn.microsoft.com/en-us/library/bb531344.aspx#BK_CRT):

The printf and scanf family of functions are now defined inline.

The definitions of all of the printf and scanf functions have been moved inline into stdio.h, conio.h, and other CRT headers. This is a breaking change that leads to a linker error (LNK2019, unresolved external symbol) for any programs that declared these functions locally without including the appropriate CRT headers. If possible, you should update the code to include the CRT headers (that is, add #include ) and the inline functions, but if you do not want to modify your code to include these header files, an alternative solution is to add an additional library to your linker input, legacy_stdio_definitions.lib.

To add this library to your linker input in the IDE, open the context menu for the project node, choose Properties, then in the Project Properties dialog box, choose Linker, and edit the Linker Input to add legacy_stdio_definitions.lib to the semi-colon-separated list.

If your project links with static libraries that were compiled with a release of Visual C++ earlier than 2015, the linker might report an unresolved external symbol. These errors might reference internal stdio definitions for _iob, _iob_func, or related imports for certain stdio functions in the form of __imp_*. Microsoft recommends that you recompile all static libraries with the latest version of the Visual C++ compiler and libraries when you upgrade a project. If the library is a third-party library for which source is not available, you should either request an updated binary from the third party or encapsulate your usage of that library into a separate DLL that you compile with the older version of the Visual C++ compiler and libraries.

$this->where('email', $email)->where('password', $password) 

is returning a Builder object which you could use to append more where filters etc.

To get the result you need:

$userRecord = $this->where('email', $email)->where('password', $password)->first();

Using setOnItemClickListener is the correct answer, but if you have a keyboard you can change selection even with arrows (no click is performed), so, you need to implement also setOnItemSelectedListener :

myListView.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> adapterView, View view, int position, long l) {
     MyObject tmp=(MyObject) adapterView.getItemAtPosition(position);
         }
            @Override
            public void onNothingSelected(AdapterView<?> adapterView) {
                // your stuff
            }
        });

You can also use ng-template, I think that would be more efficient while run time :)

<div ng-if="!test.view; else somethingElse">1</div>
<ng-template #somethingElse>
    <div>2</div>
</ng-template>

Here's a quick, admittedly butchered response, but in a sentence:

1NF : Your table is organized as an unordered set of data, and there are no repeating columns.

2NF: You don't repeat data in one column of your table because of another column.

3NF: Every column in your table relates only to your table's key -- you wouldn't have a column in a table that describes another column in your table which isn't the key.

For more detail, see wikipedia...

You must use OverridePendingTransition method to achieve it, which is in the Activity class. Sample Animations in the apidemos example's res/anim folder. Check it. More than check the demo in ApiDemos/App/Activity/animation.

Example:

@Override
public void onResume(){
    // TODO LC: preliminary support for views transitions
    this.overridePendingTransition(R.anim.in_from_right, R.anim.out_to_left);
}

import pandas as pd
import numpy as np

print(pd.Series(name_of_array).value_counts())

I use these defines:

/** Use to init the clock */
#define TIMER_INIT \
    LARGE_INTEGER frequency; \
    LARGE_INTEGER t1,t2; \
    double elapsedTime; \
    QueryPerformanceFrequency(&frequency);


/** Use to start the performance timer */
#define TIMER_START QueryPerformanceCounter(&t1);

/** Use to stop the performance timer and output the result to the standard stream. Less verbose than \c TIMER_STOP_VERBOSE */
#define TIMER_STOP \
    QueryPerformanceCounter(&t2); \
    elapsedTime=(float)(t2.QuadPart-t1.QuadPart)/frequency.QuadPart; \
    std::wcout<<elapsedTime<<L" sec"<<endl;

Usage (brackets to prevent redefines):

TIMER_INIT

{
   TIMER_START
   Sleep(1000);
   TIMER_STOP
}

{
   TIMER_START
   Sleep(1234);
   TIMER_STOP
}

Output from usage example:

1.00003 sec
1.23407 sec

If you are working on windows, you can use pywin32 (old link: see update below).

I found an example here:

import win32com.client

wmi = win32com.client.GetObject ("winmgmts:")
for usb in wmi.InstancesOf ("Win32_USBHub"):
    print usb.DeviceID

Update Apr 2020:

'pywin32' release versions from 218 and up can be found here at github. Current version 227.

Your code looks good, did you forget to install PostFix on your server?

sudo apt-get install postfix

It worked for me ;)

Cheers

Use @Deprecated on method. Don't forget about clarifying javadoc field:

/**
 * Does some thing in old style.
 *
 * @deprecated use {@link #new()} instead.  
 */
@Deprecated
public void old() {
// ...
}

You have to put your main queue dispatching in the block that runs the computation. For example (here I create a dispatch queue and don't use a global one):

dispatch_queue_t queue = dispatch_queue_create("com.example.MyQueue", NULL);
dispatch_async(queue, ^{
  // Do some computation here.

  // Update UI after computation.
  dispatch_async(dispatch_get_main_queue(), ^{
    // Update the UI on the main thread.
  });
});

Of course, if you create a queue don't forget to dispatch_release if you're targeting an iOS version before 6.0.

<?php 
 $current = strtotime(date("Y-m-d"));
 $date    = strtotime("2014-09-05");

 $datediff = $date - $current;
 $difference = floor($datediff/(60*60*24));
 if($difference==0)
 {
    echo 'today';
 }
 else if($difference > 1)
 {
    echo 'Future Date';
 }
 else if($difference > 0)
 {
    echo 'tomorrow';
 }
 else if($difference < -1)
 {
    echo 'Long Back';
 }
 else
 {
    echo 'yesterday';
 }  
?>

The function you're looking for is 'Insert'. It takes as its parameters the index you want to insert at, and an array of values to use for the new row values. Typical usage might include:

myDataGridView.Rows.Insert(4,new object[]{value1,value2,value3});

or something to that effect.

@SchizoDuckie's answer is very elegant and lightweight, but due to Webkit's lack of implementation for scrollHeight (see here), does not work on Webkit-based browsers (Safari, Chrome, various and sundry mobile platforms).

For this basic idea to work on Webkit along with Gecko and Trident browsers, one need only replace

<body onload='parent.resizeIframe(document.body.scrollHeight)'>

with

<body onload='parent.resizeIframe(document.body.offsetHeight)'>

So long as everything is on the same domain, this works quite well.

Try with <button type="submit"> you can perform the functionality of submitform() by doing <form ....... onsubmit="submitform()">

JSONObject site = (JSONObject)jsonSites.get(i); // Exception happens here.

The return type of jsonSites.get(i) is JSONArray not JSONObject. Because sites have two '[', two means there are two arrays here.

Use mathematics first find square root of number then start loop till the number ends which you get after square rooting. check for each value whether the given number is divisible by the iterating value .if any value divides the given number then it is not a prime number otherwise prime. Here is the code

 bool is_Prime(int n)
 {

   int square_root = sqrt(n); // use math.h
   int toggle = 1;
   for(int i = 2; i <= square_root; i++)
   {
     if(n%i==0)
     { 
        toggle = 0;
        break;
     }
   }

   if(toggle)
     return true;
   else
     return false;

 } 

You can also try

  Calendar calendar = Calendar.getInstance();
  System.out.println(calendar.getTimeInMillis());

getTimeInMillis() - the current time as UTC milliseconds from the epoch

$('div[id ^= "player_"]');

This worked for me..select all Div starts with "players_" keyword and display it.

Find the location of the .bash_profile file and enter the following into the file:

setterm -blength 0

Which will set the amount of time the beep happens to 0 and thus no beep.

    UIBarButtonItem *rightBarButtonItem = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(add:)];
self.navigationItem.rightBarButtonItem = rightBarButtonItem;

Are you sure you can't alter the HTML in the popup window?

If you can, add a <script> tag at the end of the popup's HTML, and call window.print() inside it. Then it won't be called until the HTML has loaded.

yes Fragment.class does not implement finish()

When working with fragments, instead of using this or refering to the context, always use getActivity(). You should call

$query="SELECT * FROM contacts";
$result=mysql_query($query);

function user() { 

       parent::Model(); 

} 

=> class name is User, construct name is User.

function User() { 

       parent::Model(); 

} 

You mean like:

String names[] = {"Ankit","Bohra","Xyz"};

But you can only do this in the same statement when you declare it

db.example.updateMany({},{"$unset":{"tags.words":1}})

We can also use this to update multiple documents.

I've deleted java files at windows/system32 and I also have removed c:\ProgramData\Oracle\Java\javapath from the PATH variable, because there was 3 symlinks to java 1.8 files.

I had JDK 1.7 in the %JAVA_HOME% variable and java1.7/bin in the PATH.

PS1: My problem was between Java 1.7 and Java 1.8.

PS2: I can't add this as a comment to Victor's answer because I haven't enough points.

While the solution of moving the contact_email to parameters.yml is easy, as proposed in other answers, that can easily clutter your parameters file if you deal with many bundles or if you deal with nested blocks of configuration.

• First, I'll answer strictly the question.
• Later, I'll give an approach for getting those configs from services without ever passing via a common space as parameters.

FIRST APPROACH: Separated config block, getting it as a parameter

With an extension (more on extensions here) you can keep this easily "separated" into different blocks in the config.yml and then inject that as a parameter gettable from the controller.

Inside your Extension class inside the DependencyInjection directory write this:

class MyNiceProjectExtension extends Extension
{
    public function load( array $configs, ContainerBuilder $container )
    {
        // The next 2 lines are pretty common to all Extension templates.
        $configuration = new Configuration();
        $processedConfig = $this->processConfiguration( $configuration, $configs );

        // This is the KEY TO YOUR ANSWER
        $container->setParameter( 'my_nice_project.contact_email', $processedConfig[ 'contact_email' ] );

        // Other stuff like loading services.yml
    }

Then in your config.yml, config_dev.yml and so you can set

my_nice_project:
    contact_email: [email protected]

To be able to process that config.yml inside your MyNiceBundleExtension you'll also need a Configuration class in the same namespace:

class Configuration implements ConfigurationInterface
{
    public function getConfigTreeBuilder()
    {
        $treeBuilder = new TreeBuilder();
        $rootNode = $treeBuilder->root( 'my_nice_project' );

        $rootNode->children()->scalarNode( 'contact_email' )->end();

        return $treeBuilder;
    }
}

Then you can get the config from your controller, as you desired in your original question, but keeping the parameters.yml clean, and setting it in the config.yml in separated sections:

$recipient = $this->container->getParameter( 'my_nice_project.contact_email' );

SECOND APPROACH: Separated config block, injecting the config into a service

For readers looking for something similar but for getting the config from a service, there is even a nicer way that never clutters the "paramaters" common space and does even not need the container to be passed to the service (passing the whole container is practice to avoid).

This trick above still "injects" into the parameters space your config.

Nevertheless, after loading your definition of the service, you could add a method-call like for example setConfig() that injects that block only to the service.

For example, in the Extension class:

class MyNiceProjectExtension extends Extension
{
    public function load( array $configs, ContainerBuilder $container )
    {
        $configuration = new Configuration();
        $processedConfig = $this->processConfiguration( $configuration, $configs );

        // Do not add a paramater now, just continue reading the services.
        $loader = new YamlFileLoader( $container, new FileLocator( __DIR__ . '/../Resources/config' ) );
        $loader->load( 'services.yml' );

        // Once the services definition are read, get your service and add a method call to setConfig()
        $sillyServiceDefintion = $container->getDefinition( 'my.niceproject.sillymanager' );
        $sillyServiceDefintion->addMethodCall( 'setConfig', array( $processedConfig[ 'contact_email' ] ) );
    }
}

Then in your services.yml you define your service as usual, without any absolute change:

services:
    my.niceproject.sillymanager:
        class: My\NiceProjectBundle\Model\SillyManager
        arguments: []

And then in your SillyManager class, just add the method:

class SillyManager
{
    private $contact_email;

    public function setConfig( $newConfigContactEmail )
    {
        $this->contact_email = $newConfigContactEmail;
    }
}

Note that this also works for arrays instead of scalar values! Imagine that you configure a rabbit queue and need host, user and password:

my_nice_project:
    amqp:
        host: 192.168.33.55
        user: guest
        password: guest

Of course you need to change your Tree, but then you can do:

$sillyServiceDefintion->addMethodCall( 'setConfig', array( $processedConfig[ 'amqp' ] ) );

and then in the service do:

class SillyManager
{
    private $host;
    private $user;
    private $password;

    public function setConfig( $config )
    {
        $this->host = $config[ 'host' ];
        $this->user = $config[ 'user' ];
        $this->password = $config[ 'password' ];
    }
}

Hope this helps!

Here are couple ways of doing it:

>>> t = ((1, 'a'), (2, 'b'))

>>> # using reversed function
>>> dict(reversed(i) for i in t)
{'a': 1, 'b': 2}

>>> # using slice operator
>>> dict(i[::-1] for i in t)
{'a': 1, 'b': 2}

You can combine conditional logic in a comprehension:

 ps = PorterStemmer()
 stop_words_english = stopwords.words('english')
 best = sorted(word_scores.items(), key=lambda x: x[1], reverse=True)[:10000]
 bestwords = set([w for w, s in best])


 def best_word_feats(words):
   return dict([(word, True) for word in words if word in bestwords])

 # with stemmer
 def best_word_feats_stem(words):
   return dict([(ps.stem(word), True) for word in words if word in bestwords])

 # with stemmer and not stopwords
 def best_word_feats_stem_stop(words):
   return dict([(ps.stem(word), True) for word in words if word in bestwords and word not in stop_words_english])

I had the same issue. Most of the times, the problem is the fact that there's a leftover file

/usr/local/var/postgres/postmaster.pid

which works for most people, but my case was different - I tried googling this issue for last 3 hours, uninstalled postresql on OSX through brew, purged the database, nothing worked.

Finally, I noticed that I had an issue with brew that whenever I tried to install anything, it popped:

Error: Permission denied @ rb_sysopen - /private/tmp/github_api_....

or something like it at the end of an install.

I simply did sudo chmod -R 777 /private/tmp and it finally works!

I'm writing this down because this might be a solution for someone else

Team->Share project is exactly what you need to do. Select SVN from the list, then click "Next". Subclipse will notice the presence of .svn directories that will ask you to confirm that the information is correct, and associate the project with subclipse.

A browser request "127.0.0.1/somefile.html" arrives unchanged to the local webserver, while "localhost/somefile.html" may arrive as "0:0:0:0:0:0:0:1/somefile.html" if IPv6 is supported. So the latter can be processed as going from a domain to another.

Regexp solution:

ref = ref.replace(/^F0/, "");

plain solution:

if (ref.substr(0, 2) == "F0")
     ref = ref.substr(2);

Your index.php code is correct. I am including the updated code for common.php below then I will explain the differences.

<?php 
     $class = ($page == 'one') ? 'class="active"' : '';
     $nav = <<<EOD
        <div id="nav">
            <ul>
               <li><a $class href="index.php">Tab1</a>/</li>
               <li><a href="two.php">Tab2</a></li>
               <li><a href="three.php">Tab3</a></li>
           </ul>
        </div>
 EOD;
 ?>

The first issue is that you need to make sure that the end declaration for your heredoc -- EOD; -- is not indented at all. If it is indented, then you will get errors.

As for your issue with the PHP code not running within the heredoc statement, that is because you are looking at it wrong. Using a heredoc statement is not the same as closing the PHP tags. As such, you do not need to try reopening them. That will do nothing for you. The way the heredoc syntax works is that everything between the opening and closing is displayed exactly as written with the exception of variables. Those are replaced with the associated value. I removed your logic from the heredoc and used a tertiary function to determine the class to make this easier to see (though I don't believe any logical statements will work within the heredoc anyway)

To understand the heredoc syntax, it is the same as including it within double quotes ("), but without the need for escaping. So your code could also be written like this:

<?php 
     $class = ($page == 'one') ? 'class="active"' : '';
     $nav = "<div id=\"nav\">
            <ul>
               <li><a $class href=\"index.php\">Tab1</a>/</li>
               <li><a href=\"two.php\">Tab2</a></li>
               <li><a href=\"three.php\">Tab3</a></li>
           </ul>
        </div>";
 ?>

It will do exactly the same thing, just is written somewhat differently. Another difference between heredoc and the string is that you can escape out of the string in the middle where you can't in the heredoc. Using this logic, you can produce the following code:

<?php 
     $nav = "<div id=\"nav\">
            <ul>
               <li><a ".(($page == 'one') ? 'class="active"' : '')." href=\"index.php\">Tab1</a>/</li>
               <li><a href=\"two.php\">Tab2</a></li>
               <li><a href=\"three.php\">Tab3</a></li>
           </ul>
        </div>";
 ?>

Then you can include the logic directly in the string like you originally intended.

Whichever method you choose makes very little (if any) difference in the performance of the script. It mostly boils down to preference. Either way, you need to make sure you understand how each works.

You should pass the object to get method of the field, so

  Field field = object.getClass().getDeclaredField(fieldName);    
  field.setAccessible(true);
  Object value = field.get(object);

I threw together a small library for this since I do think there are valid use cases for manipulating stylesheets in JS. Reasons being:

• Setting styles that must be calculated or retrieved - for example setting the user's preferred font-size from a cookie.
• Setting behavioural (not aesthetic) styles, especially for UI widget/plugin developers. Tabs, carousels, etc, often require some basic CSS simply to function - shouldn't demand a stylesheet for the core function.
• Better than inline styles since CSS rules apply to all current and future elements, and don't clutter the HTML when viewing in Firebug / Developer Tools.

In .NET you don't find only C#. You can find Visual Basic for example. If a job requires .NET knowledge, probably it need a programmer who knows the entire set of languages provided by the .NET framework.

The easiest way is to use LINQ's Union method:

var aUb = A.Union(B).ToList();

(base) C:\WINDOWS\system32>conda install C:\Users\Todd\Downloads\opencv3-3.1.0-py35_0.tar.bz2

I ran this command from anaconda terminal after I downloaded the version from https://anaconda.org/menpo/opencv3/files

This is the only way I could get cv2 to work and I tried everything for two days.

I resolved in This Way (it's a little bit laboriouse, but it's surely the faster in runtime).

In VB (sorry, but I think it's not hard translate it in C#), I make this substitution with RE:

(?<Attr><(.*ComponentModel\.)Bindable\(True\)>)( |\r\n)*(?<Def>(Public|Private|Friend|Protected) .*Property )(?<Name>[^ ]*) As (?<Type>.*?)[ |\r\n](?![ |\r\n]*Get)

with:

Private _${Name} As ${Type}\r\n${Attr}\r\n${Def}${Name} As ${Type}\r\nGet\r\nReturn _${Name}\r\nEnd Get\r\nSet (Value As ${Type})\r\nIf _${Name} <> Value Then \r\n_${Name} = Value\r\nRaiseEvent PropertyChanged(Me, New ComponentModel.PropertyChangedEventArgs("${Name}"))\r\nEnd If\r\nEnd Set\r\nEnd Property\r\n

This transofrm all code like this:

<Bindable(True)>
Protected Friend Property StartDate As DateTime?

In

Private _StartDate As DateTime?
<Bindable(True)>
Protected Friend Property StartDate As DateTime?
    Get
        Return _StartDate
    End Get
    Set(Value As DateTime?)
        If _StartDate <> Value Then
            _StartDate = Value
            RaiseEvent PropertyChange(Me, New ComponentModel.PropertyChangedEventArgs("StartDate"))
        End If
    End Set
End Property

And If I want to have a more readable code, I can be the opposite just making the following substitution:

Private _(?<Name>.*) As (?<Type>.*)[\r\n ]*(?<Attr><(.*ComponentModel\.)Bindable\(True\)>)[\r\n ]*(?<Def>(Public|Private|Friend|Protected) .*Property )\k<Name> As \k<Type>[\r\n ]*Get[\r\n ]*Return _\k<Name>[\r\n ]*End Get[\r\n ]*Set\(Value As \k<Type>\)[\r\n ]*If _\k<Name> <> Value Then[\r\n ]*_\k<Name> = Value[\r\n ]*RaiseEvent PropertyChanged\(Me, New (.*ComponentModel\.)PropertyChangedEventArgs\("\k<Name>"\)\)[\r\n ]*End If[\r\n ]*End Set[\r\n ]*End Property

With

${Attr} ${Def} ${Name} As ${Type}

I throw to replace the IL code of the set method, but I can't write a lot of compiled code in IL... If a day I write it, I'll say you!

I'm not quite sure if you mean 'can i use sqlite (websql) in chrome' or 'can i use sqlite (websql) in firefox', so I'll answer both:

• You cannot use WebSQL in Firefox. (sql.js is an option, but really, 1.5 mb of js for a database?)
• You can definitely use WebSQL in a chrome extension. See for instance the webkit window.openDatabase docs for an introduction

Note that WebSQL is not a full-access pipe into an .sqlite database. It's WebSQL. You will not be able to run some specific queries like VACUUM

It's awesome for Create / Read / Update / Delete though. I made a little library that helps with all the annoying nitty gritty like creating tables and querying and a provides a little ORM/ActiveRecord pattern with relations and all and a huge stack of examples that should get you started in no-time, you can check that here

Also, be aware that if you want to build a FireFox extension: Their extension format is about to change. Make sure you want to invest the time twice.

While the WebSQL spec has been deprecated for years, even now in 2017 still does not look like it will be be removed from Chrome for the foreseeable time. They are tracking usage statistics and there are still a large number of chrome extensions and websites out there in the real world implementing the spec.

Lists themselves are thread-safe. In CPython the GIL protects against concurrent accesses to them, and other implementations take care to use a fine-grained lock or a synchronized datatype for their list implementations. However, while lists themselves can't go corrupt by attempts to concurrently access, the lists's data is not protected. For example:

L[0] += 1

is not guaranteed to actually increase L[0] by one if another thread does the same thing, because += is not an atomic operation. (Very, very few operations in Python are actually atomic, because most of them can cause arbitrary Python code to be called.) You should use Queues because if you just use an unprotected list, you may get or delete the wrong item because of race conditions.

Keyguard basically refers to the code that handles the unlocking of the phone. it's like the keypad lock on your nokia phone a few years back just with the utility on a touchscreen.

you can find more info it you look in android/app or com\android\internal\policy\impl

Good Luck !

Do not forget that you also can pass these use variables by reference.

The use cases are when you need to change the use'd variable from inside of your callback (e.g. produce the new array of different objects from some source array of objects).

$sourcearray = [ (object) ['a' => 1], (object) ['a' => 2]];
$newarray = [];
array_walk($sourcearray, function ($item) use (&$newarray) {
    $newarray[] = (object) ['times2' => $item->a * 2];
});
var_dump($newarray);

Now $newarray will comprise (pseudocode here for brevity) [{times2:2},{times2:4}].

On the contrary, using $newarray with no & modifier would make outer $newarray variable be read-only accessible from within the closure scope. But $newarray within closure scope would be a completelly different newly created variable living only within the closure scope.

Despite both variables' names are the same these would be two different variables. The outer $newarray variable would comprise [] in this case after the code has finishes.

You have configured the auth.php and used members table for authentication but there is no user_email field in the members table so, Laravel says

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'user_email' in 'where clause' (SQL: select * from members where user_email = ? limit 1) (Bindings: array ( 0 => '[email protected]', ))

Because, it tries to match the user_email in the members table and it's not there. According to your auth configuration, laravel is using members table for authentication not users table.

INSERT syntax cannot have WHERE clause. The only time you will find INSERT has WHERE clause is when you are using INSERT INTO...SELECT statement.

The first syntax is already correct.

Some firewalls do that if a connection is idle for x number of minutes. Some ISPs set their routers to do that for various reasons as well.

In this day and age, you'll need to gracefully handle (re-establish as needed) that condition.

Here's the link you're looking for:

link list by using node class and linked list class

this is just an example not the complete functionality of linklist, append function and printing a linklist is explained in the code

code :

#include<iostream>
using namespace std;

Node class

class Node{
    public:
    int data;
    Node* next=NULL;
    Node(int data)
        {
            this->data=data;


        }   
    };

link list class named as ll

class ll{
    public:
        Node* head;

ll(Node* node)
    {
        this->head=node;
    }

void append(int data)
    {
        Node* temp=this->head;
        while(temp->next!=NULL)
            {
                temp=temp->next;
            }
        Node* newnode= new Node(data);
        // newnode->data=data;
        temp->next=newnode;
    }
void print_list()
    {   cout<<endl<<"printing entire link list"<<endl;
        Node* temp= this->head;
        while(temp->next!=NULL)
            {
                cout<<temp->data<<endl;
                temp=temp->next;
            }
        cout<<temp->data<<endl;;

    }
};

main function

int main()
{
  cout<<"hello this is an example of link list in cpp using classes"<<endl;
  ll list1(new Node(1));
  list1.append(2);
  list1.append(3);
  list1.print_list();
  }

thanks ???

If you want the current month you can use DateTime.Now.ToString("MMMM") to get the full month or DateTime.Now.ToString("MMM") to get an abbreviated month.

If you have some other date that you want to get the month string for, after it is loaded into a DateTime object, you can use the same functions off of that object:
dt.ToString("MMMM") to get the full month or dt.ToString("MMM") to get an abbreviated month.

Reference: Custom Date and Time Format Strings

Alternatively, if you need culture specific month names, then you could try these: DateTimeFormatInfo.GetAbbreviatedMonthName Method
DateTimeFormatInfo.GetMonthName Method

Better to use procedure like that:

CREATE OR REPLACE FUNCTION timestamp_diff
(
start_time_in TIMESTAMP
, end_time_in TIMESTAMP
)
RETURN NUMBER
AS
l_days NUMBER;
l_hours NUMBER;
l_minutes NUMBER;
l_seconds NUMBER;
l_milliseconds NUMBER;
BEGIN
SELECT extract(DAY FROM end_time_in-start_time_in)
, extract(HOUR FROM end_time_in-start_time_in)
, extract(MINUTE FROM end_time_in-start_time_in)
, extract(SECOND FROM end_time_in-start_time_in)
INTO l_days, l_hours, l_minutes, l_seconds
FROM dual;

l_milliseconds := l_seconds*1000 + l_minutes*60*1000 + l_hours*60*60*1000 + l_days*24*60*60*1000;
RETURN l_milliseconds;

END;

You can check it by calling:

SELECT timestamp_diff (TO_TIMESTAMP('12.04.2017 12:00:00.00', 'DD.MM.YYYY HH24:MI:SS.FF'), 
                      TO_TIMESTAMP('12.04.2017 12:00:01.111', 'DD.MM.YYYY HH24:MI:SS.FF')) 
            as milliseconds
    FROM DUAL;

This is what I did: Call JSON.stringify twice and compare the two strings...

Drawbacks:

• You can only know whether the whole object changes
• You have to detect changes manually
• You better have only primitive fields in the object(no properties, no functions...)

I had the same issue, I just have to remove the HTTP protocol from the URL. That's it.

I hope it works for you.

Ravi, for 4.0.1-rc.1:

1. Add all <option> elements inside <select>.
2. call $element.val(yourarray).trigger("change"); after select2 init function.

HTML:

<select name="Tags" id="Tags" class="form-control input-lg select2" multiple="multiple">
       <option value="1">tag 1</option>
       <option value="2">tag 2</option>
       <option value="3">tag 3</option>
 </select>

JS:

var $tagsControl = $("#Tags").select2({
        ajax: {
            url: '/Tags/Search',
            dataType: 'json',
            delay: 250,
            results: function (data) {
                return {
                    results: $.map(data, function (item) {
                        return {
                            text: item.text,
                            id: item.id
                        }
                    })
                };
            },
            cache: false
        },
        minimumInputLength: 2,
        maximumSelectionLength: 6
    });

    var data = [];
    var tags = $("#Tags option").each(function () {
        data.push($(this).val());
    });
    $tagsControl.val(data).trigger("change");

This issue was reported but it still opened. https://github.com/select2/select2/issues/3116#issuecomment-146568753

To my knowledge, you cannot disable the browser window.

What you can do is create a jQuery (or a similar kind of ) popup and when this popup appears your parent browser will be disabled.

Open your child page in popup.

I use this code ...

 function rmDirectory($dir) {
        foreach(glob($dir . '/*') as $file) {
            if(is_dir($file))
                rrmdir($file);
            else
                unlink($file);
        }
        rmdir($dir);
    }

or this one...

<?php 
public static function delTree($dir) { 
   $files = array_diff(scandir($dir), array('.','..')); 
    foreach ($files as $file) { 
      (is_dir("$dir/$file")) ? delTree("$dir/$file") : unlink("$dir/$file"); 
    } 
    return rmdir($dir); 
  } 
?>

Visibility : Hidden Vs Collapsed

Consider following code which only shows three Labels and has second Label visibility as Collapsed:

 <StackPanel Orientation="Horizontal" VerticalAlignment="Top" HorizontalAlignment="Center">
    <StackPanel.Resources>
        <Style TargetType="Label">
            <Setter Property="Height" Value="30" />
            <Setter Property="Margin" Value="0"/>
            <Setter Property="BorderBrush" Value="Black"/>
            <Setter Property="BorderThickness" Value="1" />
        </Style>
    </StackPanel.Resources>
    <Label Width="50" Content="First"/>
    <Label Width="50" Content="Second" Visibility="Collapsed"/>
    <Label Width="50" Content="Third"/>
</StackPanel>

Output Collapsed:

Now change the second Label visibility to Hiddden.

<Label Width="50" Content="Second" Visibility="Hidden"/>

Output Hidden:

As simple as that.

You are exceeding the length of int datatype. You can use UNSIGNED attribute to support that value.

SIGNED INT can support till 2147483647 and with UNSIGNED INT allows double than this. After this you still want to save data than use CHAR or VARCHAR with length 10

Late to the party, but this may help anyone looking for a quick solution:

you can use bin(ord('b')).replace('b', '')bin() it gives you the binary representation with a 'b' after the last bit, you have to remove it. Also ord() gives you the ASCII number to the char or 8-bit/1 Byte coded character.

The Stream API was designed to make it easy to write computations in a way that was abstracted away from how they would be executed, making switching between sequential and parallel easy.

However, just because its easy, doesn't mean its always a good idea, and in fact, it is a bad idea to just drop .parallel() all over the place simply because you can.

First, note that parallelism offers no benefits other than the possibility of faster execution when more cores are available. A parallel execution will always involve more work than a sequential one, because in addition to solving the problem, it also has to perform dispatching and coordinating of sub-tasks. The hope is that you'll be able to get to the answer faster by breaking up the work across multiple processors; whether this actually happens depends on a lot of things, including the size of your data set, how much computation you are doing on each element, the nature of the computation (specifically, does the processing of one element interact with processing of others?), the number of processors available, and the number of other tasks competing for those processors.

Further, note that parallelism also often exposes nondeterminism in the computation that is often hidden by sequential implementations; sometimes this doesn't matter, or can be mitigated by constraining the operations involved (i.e., reduction operators must be stateless and associative.)

In reality, sometimes parallelism will speed up your computation, sometimes it will not, and sometimes it will even slow it down. It is best to develop first using sequential execution and then apply parallelism where

(A) you know that there's actually benefit to increased performance and

(B) that it will actually deliver increased performance.

(A) is a business problem, not a technical one. If you are a performance expert, you'll usually be able to look at the code and determine (B), but the smart path is to measure. (And, don't even bother until you're convinced of (A); if the code is fast enough, better to apply your brain cycles elsewhere.)

The simplest performance model for parallelism is the "NQ" model, where N is the number of elements, and Q is the computation per element. In general, you need the product NQ to exceed some threshold before you start getting a performance benefit. For a low-Q problem like "add up numbers from 1 to N", you will generally see a breakeven between N=1000 and N=10000. With higher-Q problems, you'll see breakevens at lower thresholds.

But the reality is quite complicated. So until you achieve experthood, first identify when sequential processing is actually costing you something, and then measure if parallelism will help.

Always try to log in using those credentials with SQL Management Studio. This might reveal some more details that you don't get at runtime in your code. I had checked the SQL + Windows authentication, restarted the server but still no luck. After trying to log in using SQL Management, I got this prompt:

Somehow the password had expired although the login was created just minutes before. Anyway, new password set, connection string updated and all's fine.

If you're using Express, then you can use its compress method as part of the configuration:

var express = require('express');
var app = express.createServer();
app.use(express.compress());

And you can find more on compress here: http://expressjs.com/api.html#compress

And if you're not using Express... Why not, man?! :)

NOTE: (thanks to @ankitjaininfo) This middleware should be one of the first you "use" to ensure all responses are compressed. Ensure that this is above your routes and static handler (eg. how I have it above).

NOTE: (thanks to @ciro-costa) Since express 4.0, the express.compress middleware is deprecated. It was inherited from connect 3.0 and express no longer includes connect 3.0. Check Express Compression for getting the middleware.

Try this replaceAll: http://dumpsite.com/forum/index.php?topic=4.msg8#msg8

String.prototype.replaceAll = function(str1, str2, ignore) 
{
    return this.replace(new RegExp(str1.replace(/([\/\,\!\\\^\$\{\}\[\]\(\)\.\*\+\?\|\<\>\-\&])/g,"\\$&"),(ignore?"gi":"g")),(typeof(str2)=="string")?str2.replace(/\$/g,"$$$$"):str2);
} 

It is very fast, and it will work for ALL these conditions that many others fail on:

"x".replaceAll("x", "xyz");
// xyz

"x".replaceAll("", "xyz");
// xyzxxyz

"aA".replaceAll("a", "b", true);
// bb

"Hello???".replaceAll("?", "!");
// Hello!!!

Let me know if you can break it, or you have something better, but make sure it can pass these 4 tests.

Password is a reserved word. Bracket that field name to avoid confusing the db engine.

INSERT into Login (Username, [Password])

Your sub-query is just incomplete, that's all. See the query below with my addictions:

INSERT INTO customers ( customer_id, firstname, surname ) 
VALUES ((SELECT MAX( customer_id ) FROM customers) +1), 'jim', 'sock')

// a wrapper closure around executing a string                                  
// can take either a string or a list of strings (for arguments with spaces)    
// prints all output, complains and halts on error                              
def runCommand = { strList ->
  assert ( strList instanceof String ||
           ( strList instanceof List && strList.each{ it instanceof String } ) \
)
  def proc = strList.execute()
  proc.in.eachLine { line -> println line }
  proc.out.close()
  proc.waitFor()

  print "[INFO] ( "
  if(strList instanceof List) {
    strList.each { print "${it} " }
  } else {
    print strList
  }
  println " )"

  if (proc.exitValue()) {
    println "gave the following error: "
    println "[ERROR] ${proc.getErrorStream()}"
  }
  assert !proc.exitValue()
}

void Fun(int *Pointer)
{
  //if you want to manipulate the content of the pointer:
  *Pointer=10;
  //Here we are changing the contents of Pointer to 10
}

* before the pointer means the content of the pointer (except in declarations!)

& before the pointer (or any variable) means the address

EDIT:

int someint=15;
//to call the function
Fun(&someint);
//or we can also do
int *ptr;
ptr=&someint;
Fun(ptr);

You can achieve fall through like c++ by the goto keyword.

EX:

switch(num)
{
   case 1:
      goto case 3;
   case 2:
      goto case 3;
   case 3:
      //do something
      break;
   case 4:
      //do something else
      break;
   case default:
      break;
}

My approach is to store the PID to a file in /tmp, and to find the right process using the -S option for ssh. That might be a misuse but works for me.

#!/bin/bash

TARGET_REDIS=${1:-redis.someserver.com}
PROXY="proxy.somewhere.com"

LOCAL_PORT=${2:-6379}

if [ "$1" == "stop" ] ; then
    kill `cat /tmp/sshTunel${LOCAL_PORT}-pid`
    exit
fi

set -x

ssh -f -i ~/.ssh/aws.pem centos@$PROXY -L $LOCAL_PORT:$TARGET_REDIS:6379 -N -S /tmp/sshTunel$LOCAL_PORT  ## AWS DocService dev, DNS alias
# SSH_PID=$! ## Only works with &
SSH_PID=`ps aux | grep sshTunel${LOCAL_PORT} | grep -v grep | awk '{print $2}'`
echo $SSH_PID > /tmp/sshTunel${LOCAL_PORT}-pid

Better approach might be to query for the SSH_PID right before killing it, since the file might be stale and it would kill a wrong process.

It seems that this may be the answer you're looking for, I haven't tried this personally yet, but it seems like it may do the trick. With this command GIT will try to apply the changes as they were before, without trying to add all of them for commit.

git stash apply --index

here is the full explanation:

http://git-scm.com/book/en/Git-Tools-Stashing

You control how a row or column aligns its children using the mainAxisAlignment and crossAxisAlignment properties. For a row, the main axis runs horizontally and the cross axis runs vertically. For a column, the main axis runs vertically and the cross axis runs horizontally.

 mainAxisAlignment: MainAxisAlignment.center,
 crossAxisAlignment: CrossAxisAlignment.center,

Another usage of lambda and sorted is like the following:

Given the input array: people = [[7,0],[4,4],[7,1],[5,0],[6,1],[5,2]]

The line: people_sort = sorted(people, key = lambda x: (-x[0], x[1])) will give a people_sort list as [[7,0],[7,1],[6,1],[5,0],[5,2],[4,4]]

In this case, key=lambda x: (-x[0], x[1]) basically tells sorted to firstly sort the array based on the value of the first element of each of the instance(in descending order as the minus sign suggests), and then within the same subgroup, sort based on the second element of each of the instance(in ascending order as it is the default option).

Hope this is some useful information to you!

In Access 2007 you just need to use Application.FileDialog.

Here is the example from the Access documentation:

' Requires reference to Microsoft Office 12.0 Object Library. '
Private Sub cmdFileDialog_Click()
   Dim fDialog As Office.FileDialog
   Dim varFile As Variant

   ' Clear listbox contents. '
   Me.FileList.RowSource = ""

   ' Set up the File Dialog. '
   Set fDialog = Application.FileDialog(msoFileDialogFilePicker)

   With fDialog

      ' Allow user to make multiple selections in dialog box '
      .AllowMultiSelect = True

      ' Set the title of the dialog box. '
      .Title = "Please select one or more files"

      ' Clear out the current filters, and add our own.'
      .Filters.Clear
      .Filters.Add "Access Databases", "*.MDB"
      .Filters.Add "Access Projects", "*.ADP"
      .Filters.Add "All Files", "*.*"

      ' Show the dialog box. If the .Show method returns True, the '
      ' user picked at least one file. If the .Show method returns '
      ' False, the user clicked Cancel. '
      If .Show = True Then

         'Loop through each file selected and add it to our list box. '
         For Each varFile In .SelectedItems
            Me.FileList.AddItem varFile
         Next

      Else
         MsgBox "You clicked Cancel in the file dialog box."
      End If
   End With
End Sub

As the sample says, just make sure you have a reference to the Microsoft Access 12.0 Object Library (under the VBE IDE > Tools > References menu).

You can also do this:

git reset --hard <commit-hash>
git push -f origin master

and have everyone else who got the latest bad commits reset:

git reset --hard origin/master

This seemed to work for me:

LocationManager locMan = (LocationManager) activity.getSystemService(activity.LOCATION_SERVICE);
long networkTS = locMan.getLastKnownLocation(LocationManager.NETWORK_PROVIDER).getTime();

Working on Android 2.2 API (Level 8)

In [329]: %time my_data = genfromtxt('one.csv', delimiter=',')
CPU times: user 19.8 s, sys: 4.58 s, total: 24.4 s
Wall time: 24.4 s

In [330]: %time df = pd.read_csv("one.csv", skiprows=20)
CPU times: user 1.06 s, sys: 312 ms, total: 1.38 s
Wall time: 1.38 s

while(something.hasnext())
do something...
   if(contains something to process){
      do something...
      break;
   }
}

Just use the break statement;

For eg:this just prints "Breaking..."

while (true) {
     if (true) {
         System.out.println("Breaking...");
         break;
     }
     System.out.println("Did this print?");
}

EDIT: Firefox and Google Chrome now have a built-in JSON object, so you can just say alert(JSON.stringify(myArray)) without needing to use a jQuery plugin. This is not part of the Javascript language spec, so you shouldn't rely on the JSON object being present in all browsers, but for debugging purposes it's incredibly useful.

I tend to use the jQuery-json plugin as follows:

alert( $.toJSON(myArray) );

This prints the array in a format like

[5, 6, 7, 11]

However, for debugging your Javascript code, I highly recommend Firebug It actually comes with a Javascript console, so you can type out Javascript code for any page and see the results. Things like arrays are already printed in the human-readable form used above.

Firebug also has a debugger, as well as screens for helping you view and debug your HTML and CSS.

There are 2 popular state machine packages in NuGet.

Appccelerate.StateMachine (13.6K downloads + 3.82K of legacy version (bbv.Common.StateMachine))

StateMachineToolkit (1.56K downloads)

The Appccelerate lib has good documentation, but it does not support .NET 4, so I chose StateMachineToolkit for my project.

I'm taking a cue from the comments in @Dhara's answer, it sounds like you want to set a list of new_tick_locations by a function from the old x-axis to the new x-axis. The tick_function below takes in a numpy array of points, maps them to a new value and formats them:

import numpy as np
import matplotlib.pyplot as plt

fig = plt.figure()
ax1 = fig.add_subplot(111)
ax2 = ax1.twiny()

X = np.linspace(0,1,1000)
Y = np.cos(X*20)

ax1.plot(X,Y)
ax1.set_xlabel(r"Original x-axis: $X$")

new_tick_locations = np.array([.2, .5, .9])

def tick_function(X):
    V = 1/(1+X)
    return ["%.3f" % z for z in V]

ax2.set_xlim(ax1.get_xlim())
ax2.set_xticks(new_tick_locations)
ax2.set_xticklabels(tick_function(new_tick_locations))
ax2.set_xlabel(r"Modified x-axis: $1/(1+X)$")
plt.show()

You should use the key() function.

key($array)

should return the current key.

If you need the position of the current key:

array_search($key, array_keys($array));

Try to use the WEEKDAY() function.

Returns the weekday index for date (0 = Monday, 1 = Tuesday, … 6 = Sunday).

If you are using arrow or if you don't mind using arrow. You can substitute python's time formatting for arrow's one.

import logging

from arrow.arrow import Arrow


class ArrowTimeFormatter(logging.Formatter):

    def formatTime(self, record, datefmt=None):
        arrow_time = Arrow.fromtimestamp(record.created)

        if datefmt:
            arrow_time = arrow_time.format(datefmt)

        return str(arrow_time)


logger = logging.getLogger(__name__)

default_handler = logging.StreamHandler()
default_handler.setFormatter(ArrowTimeFormatter(
    fmt='%(asctime)s',
    datefmt='YYYY-MM-DD HH:mm:ss.SSS'
))

logger.setLevel(logging.DEBUG)
logger.addHandler(default_handler)

Now you can use all of arrow's time formatting in datefmt attribute.

Just for fun, here's another way:

;with counts as (
    select CustomerName, EmailAddress,
      count(*) over (partition by EmailAddress) as num
    from Customers
)
select CustomerName, EmailAddress
from counts
where num > 1

make iframe with align="middle" and put it in paragraph with style="text-aling:center":

Per https://developer.mozilla.org/en-US/docs/Web/API/WindowBase64/Base64_encoding_and_decoding and http://en.wikipedia.org/wiki/Basic_access_authentication , here is how to do Basic auth with a header instead of putting the username and password in the URL. Note that this still doesn't hide the username or password from anyone with access to the network or this JS code (e.g. a user executing it in a browser):

$.ajax({
  type: 'POST',
  url: http://theappurl.com/api/v1/method/,
  data: {},
  crossDomain: true,
  beforeSend: function(xhr) {
    xhr.setRequestHeader('Authorization', 'Basic ' + btoa(unescape(encodeURIComponent(YOUR_USERNAME + ':' + YOUR_PASSWORD))))
  }
});

In Rails 4.1.0, I have faced problem with saving latitude and longitude to MySql database. It can't save large fraction number with float data type. And I change the data type to decimal and working for me.

  def change
    change_column :cities, :latitude, :decimal, :precision => 15, :scale => 13
    change_column :cities, :longitude, :decimal, :precision => 15, :scale => 13
  end

Make sure that you're using the same Servlet API specification that your Web container supports. Refer to this chart if you're using Tomcat: http://tomcat.apache.org/whichversion.html

The Web container that you use will definitely have the API jars you require.

Tomcat 6 for example has it in apache-tomcat-6.0.26/lib/servlet-api.jar

Different Idea:

(1) You save the original file as a variable.

(2) You overwrite the original file with new information.

(3) You append the original file in the data below the new information.

Code:

with open(<filename>,'r') as contents:
      save = contents.read()
with open(<filename>,'w') as contents:
      contents.write(< New Information >)
with open(<filename>,'a') as contents:
      contents.write(save)

Set the display property to inline for the list you want this to apply to. There's a good explanation of displaying lists on A List Apart.

You will get the structure by typing the command:

.schema <tableName>

Work for arrays and lists only, not for set.

$('iframe').load(function(){
      $(".loading").remove();
    alert("iframe is done loading")
}).show();


<iframe src="http://www.google.com" style="display:none;" width="600" height="300"/>
<div class="loading" style="width:600px;height:300px;">iframe loading</div>

Also it's worth knowing that you may need to include .\ in front of the script name. For example:

.\scriptname.ps1

The angular.forEach loop can't break on a condition match.

My personal advice is to use a NATIVE FOR loop instead of angular.forEach.

The NATIVE FOR loop is around 90% faster then other for loops.

USE FOR loop IN ANGULAR:

var numbers = [0, 1, 2, 3, 4, 5];

for (var i = 0, len = numbers.length; i < len; i++) {
  if (numbers[i] === 1) {
    console.log('Loop is going to break.'); 
    break;
  }
  console.log('Loop will continue.');
}

insert into OPT       (email,        campaign_id) 
select 'mom@coxnet' as email, 100 as campaign_id from dual MINUS
select                 email,        campaign_id from OPT;

If there is already a record with [email protected]/100 in OPT, the MINUS will subtract this record from the select 'mom@coxnet' as email, 100 as campaign_id from dual record and nothing will be inserted. On the other hand, if there is no such record, the MINUS does not subract anything and the values mom@coxnet/100 will be inserted.

As p.marino has already pointed out, merge is probably the better (and more correct) solution for your problem as it is specifically designed to solve your task.

Take a look at the facilities provided by the time module

You have several conversion functions there.

Edit: see the datetime module for more OOP-like solutions. The time library linked above is kinda imperative.

Joanna Avalos answer is better, Just note that I replaced .text() to .html(), otherwise, some of the html elements inside that will be destroyed.

I found this worked best for me.

In AndroidManifest.xml <activity> element add android:windowSoftInputMode="stateHidden"

This always hides the keyboard when entering the activity.

I hope mine helps

template <typename t_int>
std::array<uint8_t, sizeof (t_int)> int2array(t_int p_value) {
    static const uint8_t _size_of (static_cast<uint8_t>(sizeof (t_int)));
    typedef std::array<uint8_t, _size_of> buffer;
    static const std::array<uint8_t, 8> _shifters = {8*0, 8*1, 8*2, 8*3, 8*4, 8*5, 8*6, 8*7};

    buffer _res;
    for (uint8_t _i=0; _i < _size_of; ++_i) {
        _res[_i] = static_cast<uint8_t>((p_value >> _shifters[_i]));
    }
    return _res;
}

The memory must be configured in several places.
Set memory_limit to 512M:

sudo vi /etc/php5/cgi/php.ini
sudo vi /etc/php5/cli/php.ini
sudo vi /etc/php5/apache2/php.ini Or /etc/php5/fpm/php.ini

Restart service:

sudo service service php5-fpm restart
sudo service service nginx restart

or

sudo service apache2 restart

Finally it should solve the problem of the memory_limit

ArrayList<File> directories = new ArrayList<File>(
    Arrays.asList(
        new File("your/path/").listFiles(File::isDirectory)
    )
);

If the primary key happens to be an auto_increment value, you have to remove the auto increment, then drop the primary key then re-add the auto-increment

ALTER TABLE `xx`
MODIFY `auto_increment_field` INT, 
DROP PRIMARY KEY, 
ADD PRIMARY KEY (new_primary_key);

then add back the auto increment

ALTER TABLE `xx` ADD INDEX `auto_increment_field` (auto_increment_field),
MODIFY `auto_increment_field` int auto_increment;

then set auto increment back to previous value

ALTER TABLE `xx` AUTO_INCREMENT = 5;

Reflection in C++ is very useful, in cases there you need to run some method for each member(For example: serialization, hashing, compare). I came with generic solution, with very simple syntax:

struct S1
{
    ENUMERATE_MEMBERS(str,i);
    std::string str;
    int i;
};
struct S2
{
    ENUMERATE_MEMBERS(s1,i2);
    S1 s1;
    int i2;
};

Where ENUMERATE_MEMBERS is a macro, which is described later(UPDATE):

Assume we have defined serialization function for int and std::string like this:

void EnumerateWith(BinaryWriter & writer, int val)
{
    //store integer
    writer.WriteBuffer(&val, sizeof(int));
}
void EnumerateWith(BinaryWriter & writer, std::string val)
{
    //store string
    writer.WriteBuffer(val.c_str(), val.size());
}

And we have generic function near the "secret macro" ;)

template<typename TWriter, typename T>
auto EnumerateWith(TWriter && writer, T && val) -> is_enumerable_t<T>
{
    val.EnumerateWith(write); //method generated by ENUMERATE_MEMBERS macro
}

Now you can write

S1 s1;
S2 s2;
//....
BinaryWriter writer("serialized.bin");

EnumerateWith(writer, s1); //this will call EnumerateWith for all members of S1
EnumerateWith(writer, s2); //this will call EnumerateWith for all members of S2 and S2::s1 (recursively)

So having ENUMERATE_MEMBERS macro in struct definition, you can build serialization, compare, hashing, and other stuffs without touching original type, the only requirement is to implement "EnumerateWith" method for each type, which is not enumerable, per enumerator(like BinaryWriter). Usually you will have to implement 10-20 "simple" types to support any type in your project.

This macro should have zero-overhead to struct creation/destruction in run-time, and the code of T.EnumerateWith() should be generated on-demand, which can be achieved by making it template-inline function, so the only overhead in all the story is to add ENUMERATE_MEMBERS(m1,m2,m3...) to each struct, while implementing specific method per member type is a must in any solution, so I do not assume it as overhead.

UPDATE: There is very simple implementation of ENUMERATE_MEMBERS macro(however it could be a little be extended to support inheritance from enumerable struct)

#define ENUMERATE_MEMBERS(...) \
template<typename TEnumerator> inline void EnumerateWith(TEnumerator & enumerator) const { EnumerateWithHelper(enumerator, __VA_ARGS__ ); }\
template<typename TEnumerator> inline void EnumerateWith(TEnumerator & enumerator) { EnumerateWithHelper(enumerator, __VA_ARGS__); }

// EnumerateWithHelper
template<typename TEnumerator, typename ...T> inline void EnumerateWithHelper(TEnumerator & enumerator, T &...v) 
{ 
    int x[] = { (EnumerateWith(enumerator, v), 1)... }; 
}

// Generic EnumerateWith
template<typename TEnumerator, typename T>
auto EnumerateWith(TEnumerator & enumerator, T & val) -> std::void_t<decltype(val.EnumerateWith(enumerator))>
{
    val.EnumerateWith(enumerator);
}

And you do not need any 3rd party library for these 15 lines of code ;)

I won't repeat the usual stuff about Using or freeing un-managed resources, that has all been covered. But I would like to point out what seems a common misconception.
Given the following code

Public Class LargeStuff
  Implements IDisposable
  Private _Large as string()

  'Some strange code that means _Large now contains several million long strings.

  Public Sub Dispose() Implements IDisposable.Dispose
    _Large=Nothing
  End Sub

I realise that the Disposable implementation does not follow current guidelines, but hopefully you all get the idea.
Now, when Dispose is called, how much memory gets freed?

Answer: None.
Calling Dispose can release unmanaged resources, it CANNOT reclaim managed memory, only the GC can do that. Thats not to say that the above isn't a good idea, following the above pattern is still a good idea in fact. Once Dispose has been run, there is nothing stopping the GC re-claiming the memory that was being used by _Large, even though the instance of LargeStuff may still be in scope. The strings in _Large may also be in gen 0 but the instance of LargeStuff might be gen 2, so again, memory would be re-claimed sooner.
There is no point in adding a finaliser to call the Dispose method shown above though. That will just DELAY the re-claiming of memory to allow the finaliser to run.

What worked for me was this-- On Ubuntu

1. Ctrl+F1
2. ps -e
3. kill -9 for process ids of eclipse, java and adb

1. Proper AJAX, e.g. JSONResults no partial page postback nonsense.
2. no viewstate +1
3. No renaming of the HTML IDs.
4. Clean HTML = no bloat and having a decent shot at rendering XHTML or standards compliant pages.
5. No more generated AXD javascript.

Depends on where you want to use the email. If it's on the client side, without sending it to a PHP script, JQuery (or javascript) can do the trick.

I've created a fiddle to explain the same - http://jsfiddle.net/qHcpR/

It has an alert which goes off on load and when you click the textbox itself.

When doing pan_list.append(p.last) you're doing an inplace operation, that is an operation that modifies the object and returns nothing (i.e. None).

You should do something like this :

last_list=[]
if p.last_name==None or p.last_name=="": 
    pass
last_list.append(p.last)  # Here I modify the last_list, no affectation
print last_list

How about this: I used it with a mixin

non-compliant object

@Entity
@Getter
@NoArgsConstructor
public class Telemetry {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long pk;
    private String id;
    private String organizationId;
    private String baseType;
    private String name;
    private Double lat;
    private Double lon;
    private Instant updateTimestamp;
}

Mixin:

@JsonAutoDetect(fieldVisibility = ANY, getterVisibility = NONE, setterVisibility = NONE)
public static class TelemetryMixin {}

Usage:

    ObjectMapper om = objectMapper.addMixIn(Telemetry.class, TelemetryMixin.class);
    Telemetry[] telemetries = om.readValue(someJson, Telemetry[].class);

There is nothing that says you couldn't foreach any number of classes and apply the same mixin.

If you're not familiar with mixins, they are conceptually simply: The structure of the mixin is super imposed on the target class (according to jackson, not as far as the JVM is concerned).

 function createQuestionPanel() {

        var element = document.createElement("Input");
        element.setAttribute("type", "button");
        element.setAttribute("value", "button");
        element.setAttribute("name", "button");


        var div = document.createElement("div"); <------- Create DIv Node
        div.appendChild(element);<--------------------
        document.body.appendChild(div) <------------- Then append it to body

    }

    function formvalidate() {

    }

That is most likely jQuery code (more precisely, JavaScript using the jQuery library).

The $ represents the jQuery Function, and is actually a shorthand alias for jQuery. (Unlike in most languages, the $ symbol is not reserved, and may be used as a variable name.) It is typically used as a selector (i.e. a function that returns a set of elements found in the DOM).

If you want to add a directory and all the files which are located inside it recursively, Go to the directory where the directory you want to add is located.

$ cd directory
$ git add directoryname

For IntelliJ IDEA 2019.3.4 (Ultimate Edition), the following worked for me:

1. Find the Environment variables for your project.
2. Specify, from the dropdowns, the values of "Use class path of module:" and "JRE" as in the attached screenshot.

The magic number comes from UNIX-type systems where the first few bytes of a file held a marker indicating the file type.

This error indicates you are trying to load a non-valid file type into R. For some reason, R no longer recognizes this file as an R workspace file.

Depending on what you are really after you can do something like this:

using System;
using System.Collections.Generic;
using System.Linq;

namespace SO14473321
{
    class Program
    {
        static void Main()
        {
            UniqueRandom u = new UniqueRandom(Enumerable.Range(1,10));
            for (int i = 0; i < 10; i++)
            {
                Console.Write("{0} ",u.Next());
            }
        }
    }

    class UniqueRandom
    {
        private readonly List<int> _currentList;
        private readonly Random _random = new Random();

        public UniqueRandom(IEnumerable<int> seed)
        {
            _currentList = new List<int>(seed);
        }

        public int Next()
        {
            if (_currentList.Count == 0)
            {
                throw new ApplicationException("No more numbers");
            }

            int i = _random.Next(_currentList.Count);
            int result = _currentList[i];
            _currentList.RemoveAt(i);
            return result;
        }
    }
}

You can create one:

class myDict(dict):

    def __init__(self):
        self = dict()

    def add(self, key, value):
        self[key] = value

## example

myd = myDict()
myd.add('apples',6)
myd.add('bananas',3)
print(myd)

Gives:

>>> 
{'apples': 6, 'bananas': 3}

Yes, that should work for Strings, but if you are worried about duplicates use a Set. This collection prevents duplicates without you having to do anything. A HashSet is OK to use, but it is unordered so if you want to preserve insertion order you use a LinkedHashSet.

What you can utilize is some sort of templating engine like pug (formerly jade). To enable it you should do the following:

1. npm install --save pug - to add it to the project and package.json file
2. app.set('view engine', 'pug'); - register it as a view engine in express
3. create a ./views folder and add a simple .pug file like so:

html
  head
    title= title
  body
    h1= message

note that the spacing is very important!

4. create a route that returns the processed html:

app.get('/', function (req, res) {
  res.render('index', { title: 'Hey', message: 'Hello there!'});
});

This will render an index.html page with the variables passed in node.js changed to the values you have provided. This has been taken directly from the expressjs templating engine page: http://expressjs.com/en/guide/using-template-engines.html

For more info on pug you can also check: https://github.com/pugjs/pug

Simply creating a filter will do the trick. (Answered for Angular 1.6)

.filter('trustHtml', [
        '$sce',
        function($sce) {
            return function(value) {
                return $sce.trustAs('html', value);
            }
        }
    ]);

And use this as follow in the html.

<h2 ng-bind-html="someScopeValue | trustHtml"></h2>

What solves my problem: I am using 64 bit Windows 7, so I thought I could install 64 bit Wamp. After I Installed the 32-bit version the error does not appear. So something in the developing process at Wamp went wrong...

I usually combine CSS and JavaScript approaches, so that it works without JavaScript in all browsers but IE6/7, and in IE6/7 with JavaScript on (but not off), since they does not support the :last-child pseudo-class.

$("li:last-child").addClass("last-child");

li:last-child,li.last-child{ /* ... */ }

Here is the simplest thing i could think of. Note that this program uses second command line argument (argv[1]) as a line to delete whitespaces from.

#include <string.h>
#include <stdio.h>
#include <stdlib.h>

/*The function itself with debug printing to help you trace through it.*/

char* trim(const char* str)
{
    char* res = malloc(sizeof(str) + 1);
    char* copy = malloc(sizeof(str) + 1);
    copy = strncpy(copy, str, strlen(str) + 1);
    int index = 0;

    for (int i = 0; i < strlen(copy) + 1; i++) {
        if (copy[i] != ' ')
        {
            res[index] = copy[i];
            index++;
        }
        printf("End of iteration %d\n", i);
        printf("Here is the initial line: %s\n", copy);
        printf("Here is the resulting line: %s\n", res);
        printf("\n");
    }
    return res;
}

int main(int argc, char* argv[])
{
    //trim function test

    const char* line = argv[1];
    printf("Here is the line: %s\n", line);

    char* res = malloc(sizeof(line) + 1);
    res = trim(line);

    printf("\nAnd here is the formatted line: %s\n", res);

    return 0;
}

I would like to present another answer to this as the currently accepted answer doesn't work for me (I use LibreOffice). This solution should work in Excel, LibreOffice and OpenOffice:

First, insert a new row at the beginning of the sheet. Within that row, define the names you need:

Then, in the menu bar, go to View -> Freeze Cells -> Freeze First Row. It'll look like this now:

Now whenever you scroll down in the document, the first row will be "pinned" to the top:

It is cumbersome and difficult to specify locale explicitly. You never know where your app will be used. So I think, it is better to set locale to Calender.current.locale and use DateFormatter's setLocalizedDateFormatFromTemplate method.

setLocalizedDateFormatFromTemplate(_:)

Sets the date format from a template using the specified locale for the receiver. - developer.apple.com

extension Date {
    func convertToLocaleDate(template: String) -> String {
        let dateFormatter = DateFormatter()

        let calender = Calendar.current

        dateFormatter.timeZone = calender.timeZone
        dateFormatter.locale = calender.locale
        dateFormatter.setLocalizedDateFormatFromTemplate(template)

        return dateFormatter.string(from: self)
    }
}



Date().convertToLocaleDate(template: "dd MMMM YYYY")

There is a bunch on here:

http://www.webservicex.net/WS/wscatlist.aspx

Just google for "Free WebService" or "Open WebService" and you'll find tons of open SOAP endpoints.

Remember, you can get a WSDL from any ASMX endpoint by adding ?WSDL to the url.

I'm guessing this is what you want...

When the form is submitted, check if the value is empty and if so, send a value = empty.

If so, you could do the following with jQuery.

$('form').submit(function(){
    var input = $('#test').val();
    if(input == ''){
         $('#test').val('empty');
    }    
});

HTML

<form> 
    <input id="test" type="text" />
</form>

http://jsfiddle.net/jasongennaro/NS6Ca/

Click your cursor in the box and then hit enter to see the form submit the value.

SELECT      T.TABLE_NAME, C.COLUMN_NAME
FROM        INFORMATION_SCHEMA.COLUMNS C
            INNER JOIN INFORMATION_SCHEMA.TABLES T ON T.TABLE_NAME = C.TABLE_NAME
WHERE       TABLE_TYPE = 'BASE TABLE'
            AND COLUMN_NAME = 'ColName'

This returns tables only and ignores views for anyone who is interested!

you can also use the randomizeMatrix function in the R package picante

example:

test <- matrix(c(1,1,0,1,0,1,0,0,1,0,0,1,0,1,0,0),nrow=4,ncol=4)
> test
     [,1] [,2] [,3] [,4]
[1,]    1    0    1    0
[2,]    1    1    0    1
[3,]    0    0    0    0
[4,]    1    0    1    0

randomizeMatrix(test,null.model = "frequency",iterations = 1000)

     [,1] [,2] [,3] [,4]
[1,]    0    1    0    1
[2,]    1    0    0    0
[3,]    1    0    1    0
[4,]    1    0    1    0

randomizeMatrix(test,null.model = "richness",iterations = 1000)

     [,1] [,2] [,3] [,4]
[1,]    1    0    0    1
[2,]    1    1    0    1
[3,]    0    0    0    0
[4,]    1    0    1    0
> 

The option null.model="frequency" maintains column sums and richness maintains row sums. Though mainly used for randomizing species presence absence datasets in community ecology it works well here.

This function has other null model options as well, check out following link for more details (page 36) of the picante documentation

It does seem you would have to use a MessageBodyReader here. Here's an example, using jdom:

import org.jdom.Document;
import javax.ws.rs.ext.MessageBodyReader;
import javax.ws.rs.ext.Provider;
import javax.ws.rs.ext.MediaType;
import javax.ws.rs.ext.MultivaluedMap;
import java.lang.reflect.Type;
import java.lang.annotation.Annotation;
import java.io.InputStream;

@Provider // this annotation is necessary!
@ConsumeMime("application/xml") // this is a hint to the system to only consume xml mime types
public class XMLMessageBodyReader implements MessageBodyReader<Document> {
  private SAXBuilder builder = new SAXBuilder();

  public boolean isReadable(Class type, Type genericType, Annotation[] annotations, MediaType mediaType) {
    // check if we're requesting a jdom Document
    return Document.class.isAssignableFrom(type);
  }

  public Document readFrom(Class type, Type genericType, Annotation[] annotations, MediaType mediaType, MultivaluedMap<String, String> httpHeaders, InputStream entityStream) {
    try {
      return builder.build(entityStream);
    }
    catch (Exception e) {
      // handle error somehow
    }
  } 
}

Add this class to the list of resources your jersey deployment will process (usually configured via web.xml, I think). You can then use this reader in one of your regular resource classes like this:

@Path("/somepath") @POST
public void handleXMLData(Document doc) {
  // do something with the document
}

I haven't verified that this works exactly as typed, but that's the gist of it. More reading here:

Your code will work but you need to flip the 4th and the 5th argument.

I would do it this way

$date_string = "2012-10-18";
$date_int = strtotime($date_string);
$date_date = date($date_int);
$week_number = date('W', $date_date);
echo "Weeknumber: {$week_number}.";

Also, your variable names will be confusing to you after a week of not looking at that code, you should consider reading http://net.tutsplus.com/tutorials/php/why-youre-a-bad-php-programmer/

For litespeed servers with lsphp*.* package.

Use following command to find out default set memory limit for PHP applications.

php -r "echo ini_get('memory_limit').PHP_EOL;"

To locate active php.ini file from CLI

php -i | grep php.ini

Example:

/usr/local/lsws/lsphp73/etc/php/7.3/litespeed/php.ini

To change php.ini default value to custom:

php_memory_limit=1024M #or what ever you want it set to
sed -i 's/memory_limit = .*/memory_limit = '${php_memory_limit}'/' /usr/local/lsws/lsphp73/etc/php/7.3/litespeed/php.ini

Dont forget to restart lsws with: systemctl restart lsws

While you should keep your NuGet packages.config file, you should exclude the packages folder:

#NuGet
packages/

I typically don't store binaries, or anything generated from my source, in source control. There are differing opinions on this however. If it makes things easier for your build system, do it! I would however, argue that you are not versioning these dependencies, so they will just take up space in your repository. Storing the binaries in a central location, then relying on the packages.config file to indicate which version is needed is a better solution, in my opinion.

An alternative would be instead of passing the parameters to the constructor you might have them as getter and setters and then in a @PostConstruct initialize the values as you want. In this case Spring will create the bean using the default constructor. An example is below

@Component
public class MyConstructorClass{

  String var;

  public void setVar(String var){
     this.var = var;
  }

  public void getVar(){
    return var;
  }

  @PostConstruct
  public void init(){
     setVar("var");
  }
...
}


@Service
public class MyBeanService{
  //field autowiring
  @Autowired
  MyConstructorClass myConstructorClass;

  ....
}

this solution worked for me:

var oldURL = "";
var currentURL = window.location.href;
function checkURLchange(currentURL){
    if(currentURL != oldURL){
        alert("url changed!");
        oldURL = currentURL;
    }

    oldURL = window.location.href;
    setTimeout(function() {
        checkURLchange(window.location.href);
    }, 1000);
}

checkURLchange();

Assuming you just want to check if a key exists (instead of quietly over-writing it), do this check first:

import boto3

def key_exists(mykey, mybucket):
  s3_client = boto3.client('s3')
  response = s3_client.list_objects_v2(Bucket=mybucket, Prefix=mykey)
  if response:
      for obj in response['Contents']:
          if mykey == obj['Key']:
              return True
  return False

if key_exists('someprefix/myfile-abc123', 'my-bucket-name'):
    print("key exists")
else:
    print("safe to put new bucket object")
    # try:
    #     resp = s3_client.put_object(Body="Your string or file-like object",
    #                                 Bucket=mybucket,Key=mykey)
    # ...check resp success and ClientError exception for errors...

THE EASIEST SOLUTION --> i've found is to let Material Design (1.0.0-rc4) do the work. The md-input-container will do the work for you. It concats the string and adds elipses plus it has the extra advantage of allowing you to click it to get the full text so it's the whole enchilada. You may need to set the width of the md-input-container.

HTML:

<md-input-container>
   <md-select id="concat-title" placeholder="{{mytext}}" ng-model="mytext" aria-label="label">
      <md-option ng-selected="mytext" >{{mytext}}
      </md-option>
   </md-select>
</md-input-container>

CS:

#concat-title .md-select-value .md-select-icon{
   display: none; //if you want to show chevron remove this
}
#concat-title .md-select-value{
   border-bottom: none; //if you want to show underline remove this
}

@GET does support List of Strings

Setup:
Java : 1.7
Jersey version : 1.9

Resource

@Path("/v1/test")

Subresource:

// receive List of Strings
@GET
@Path("/receiveListOfStrings")
public Response receiveListOfStrings(@QueryParam("list") final List<String> list){
    log.info("receieved list of size="+list.size());
    return Response.ok().build();
}

Jersey testcase

@Test
public void testReceiveListOfStrings() throws Exception {
    WebResource webResource = resource();
    ClientResponse responseMsg = webResource.path("/v1/test/receiveListOfStrings")
            .queryParam("list", "one")
            .queryParam("list", "two")
            .queryParam("list", "three")
            .get(ClientResponse.class);
    Assert.assertEquals(200, responseMsg.getStatus());
}

I think Fresher gave us nice way, but there is a mistake:

    <script type="text/javascript">
        function setCookie(key, value) {
            var expires = new Date();
            expires.setTime(expires.getTime() + (value * 24 * 60 * 60 * 1000));
            document.cookie = key + '=' + value + ';expires=' + expires.toUTCString();
        }

        function getCookie(key) {
            var keyValue = document.cookie.match('(^|;) ?' + key + '=([^;]*)(;|$)');
            return keyValue ? keyValue[2] : null;
        }
   </script>

You should add "value" near getTime(); otherwise the cookie will expire immediately :)

Building on Chad's answer, you also want to add that function to the onload event to ensure it is resized when the page loads as well.

jQuery.event.add(window, "load", resizeFrame);
jQuery.event.add(window, "resize", resizeFrame);

function resizeFrame() 
{
    var h = $(window).height();
    var w = $(window).width();
    $("#elementToResize").css('height',(h < 768 || w < 1024) ? 500 : 400);
}

I am using the following construct, although you might want to avoid shell=True. This gives you the output and error message for any command, and the error code as well:

process = subprocess.Popen(cmd, shell=True,
                           stdout=subprocess.PIPE, 
                           stderr=subprocess.PIPE)

# wait for the process to terminate
out, err = process.communicate()
errcode = process.returncode

You can use varchar for storing phone numbers, so you need not remove the formatting

If sheet contains unused area on the top, UsedRange.Rows.Count is not the maximum row.

This is the correct max row number.

maxrow = Sheets("..name..").UsedRange.Rows(Sheets("..name..").UsedRange.Rows.Count).Row

In some contexts using a ' character beforehand will work, but if you save to CSV and load again this is impossible.

This means that you must declare strict mode by writing "use strict" at the beginning of the file or the function to use block-scope declarations.

EX:

function test(){
    "use strict";
    let a = 1;
} 

After wasting hours on it, I have updated my version of adb and now adb devices shows my device online and I can run the app on it again.
